Description

  The present invention relates to a picking product transport system that picks up a product stored in a warehouse or the like using a picking cart and transports the picked product to a shipping destination.

  Conventionally, in places where products such as warehouses are stored, in order to increase the efficiency of picking up stored products, product storage shelves are arranged, and picking carts are placed while workers walk between each storage shelf. An operation is performed in which each product is picked up in accordance with a shipping instruction and stored in a product storage container (such as a container) loaded on a picking cart.

  Then, after storing the product in the product storage container, the operator lifts the product storage container storing the product one by one from the picking cart, loads the product on the conveyor belt, and flows it downstream. Doing work. In addition, the product storage containers that are flowed downstream by the conveyor belt for transporting are loaded by a machine onto a carry cart used for transporting to the supplier, and then transported by truck to the store of the supplier. It will be done.

  Every effort has been made to make the transporting operation of picking products as described above efficient, but for example, Patent Document 1 discloses a product provided along a product collection path. A storage means and a number indicator for designating a destination order product and displaying the order quantity are provided, and the product designated by the indicator is taken out from the product storage means by the order quantity and collected by destination. In the collection system, the order information reading means for reading the order information for each destination from the issued information recording medium by recording the order information such as the order item and the order quantity for each destination in advance, And a control means for displaying on the number display the number of orders for each ordered product related to the destination based on the order information read by the reading means. There has been disclosed.

  Then, according to this collection system, the order quantity for each ordered product related to the destination is displayed on the number display simply by causing the order information reading means to read the order information recorded on the information recording medium for each destination. Therefore, the operator transports the cart loaded with containers on the product collection route, picks the products corresponding to the number display on which the number is displayed, and displays them in the container on the cart. If it is introduced, it is said that the requested product will be collected for each required item in the container loaded on the cart.

  Further, for example, in Patent Document 2, a container having picking information attached to a parent box and a child box that are grouped together is accommodated, the child box is transported continuously to the parent box, and the picking information is stored. And picking articles into each container in the parent box and the child box, and after all the picking is completed, the container in the child box is stored in the parent box, and the parent box is shipped, A picking method for collecting a child box is disclosed.

  According to this method, since the articles are already picked individually at the picking place, there is no need to sort the articles at the delivery destination, and the delivery destination can easily identify and distribute the separately packaged articles. It becomes work. In addition, it is possible to pick items individually using a parent box, a child box, etc. at a picking place, and since the parent box and the child box are associated with each other, it is easy to identify the group, and grouping after individual picking It is considered easy.

  Further, in Patent Document 3, a parent box and a child box each containing a container for storing articles are transported to a picking work unit by a transport means in a group state, and in the picking work part, Based on the picking information for each storage body, a picking operation for picking and storing articles to be stored in each storage body is executed, and after the picking operation is completed, the main box is stored in the child box. A picking method for storing the storage body and shipping a plurality of storage bodies in a grouped state, wherein the storage body is stored in the child box against the picking work unit by the transport means. A label that is issued by a label issuing means and displays management information common to the plurality of storage bodies to be grouped and individual management information for each of the storage bodies is attached to the body, and the picking is performed. After the work is finished, the display label affixed to the container which is accommodated in the parent box, instead attached to the parent box, picking method as shipping the parent box is disclosed.

  In order to improve the overall efficiency of picking goods conveyance work, such as the collection system and picking method disclosed in the above patent document, it is very important to aim for efficiency in the picking work process. It can be seen that there is.

  However, in the collection system disclosed in Patent Document 1, it is possible to accurately pick an ordered product for each destination according to the number of orders and deliver it to the destination. When placing the container on the conveyor belt for conveyance, the operator must work to lift and load the containers one by one, and there is a problem that the burden is large.

  In addition, in order to make the transport on the belt conveyor efficient, when the containers are stacked on the belt conveyor in two layers, a heavy container in which the ordered products are stored in advance on the picking cart is used. Since it is necessary to stack two layers and load them on the belt conveyor as they are, the burden on the operator is still great.

  Then, when the containers are stacked on the downstream side of the belt conveyor, it is necessary for the operator to stack the containers one by one on the transport cart, so that the work load is extremely large. Obviously, when the containers are stacked in two stages, the burden further increases. If this is performed, for example, by robot control, the work load is reduced, but this time the distribution cost increases.

  Furthermore, since the ordered products stored in one container are in a state where products of various categories are mixed, as shown in FIG. 7, when arranging the products on the product shelf at the shipping destination. In addition, it is necessary to move between the target product shelves vertically and horizontally, which is a very complicated task and may interfere with the walking of the product buyer during the work. .

  Further, in the picking methods disclosed in Patent Documents 2 and 3, it is not necessary to sort the articles at the shipping destination, and the shipping destination can be a simple task of simply identifying and distributing the separately packaged articles. However, since the products of various categories are still mixed, as shown in FIG. 7, when arranging the products on the product shelves at the shipping destination, the target product shelves are infinitely wide. It must be moved to a very complicated operation.

  Furthermore, when stacking containers on two levels and loading them on a belt conveyor, as in the collection system of Patent Document 1, a container with a weight in which an ordered product is stored in advance on a picking cart is stacked in two stages. Since it is necessary to load it on the belt conveyor as it is, the burden on the operator becomes large.

  The present invention is for solving the above-mentioned problems, while reducing the burden of the work of transporting the product storage container (container etc.) by the picking operator, increasing the transport efficiency, further suppressing the distribution cost, and It is an object of the present invention to provide a picking product transport system that can improve the efficiency of product arrangement work at a shipping destination.

  In order to cope with the above-described problems, the present invention takes the following technical means. That is, the invention according to claim 1 is a picking product transport system for transporting a picked product to a shipping destination based on a shipping instruction, and a product storage step for storing the product in a product storage shelf in advance for each category. And a picking cart for a product that can travel freely in the front-rear direction, and one of the product storage containers assigned for each category of the products loaded in advance on the picking cart for picking. The product is moved and placed at a predetermined position for picking work on the carriage, and the product corresponding to the category assigned to the product storage container is picked from the product storage shelf and stored in the moved product storage container. On the first product storage step, and on the product storage container in which the product is stored in the first product storage step, The product storage containers are moved and placed one by two in a stacked manner, and the product corresponding to the category assigned to the product storage container is picked from the product storage shelf into the other product storage containers that have been moved and placed, A picking product storage step including a second product storage step of storing, and the product storage container and the other product storage container that are stacked in two stages after storing the product by the picking product storage step And a transfer container group loading step of stacking the transfer container group onto a transfer belt conveyor by pushing the transfer container group from the rear to the front on the picking cart. In the transporting container group loading step, the transporting container group stacked on the transporting belt conveyor is disposed downstream of the transporting belt conveyor. The transporting container group received is sequentially stacked and held in a predetermined number of times on the transporting carriage, and after a predetermined number of stacking and holding, the transporting carriage is left in the state of the loading and holding. A picking product transport system comprising a transport cart loading step for transporting to a shipping destination.

  According to the present invention, on a cart for picking work, product storage containers (containers etc.) storing picked products are stacked in two tiers, and the product storage containers (containers etc.) stacked in two tiers are combined into one container. As a group (conveying container group), it can be stacked on the conveyor belt conveyor by pushing it out from the front of the cart for picking work. The efficiency of transporting storage containers (containers, etc.) can also be improved.

  Also, on the downstream side of the transfer conveyor, a two-tiered product storage container (container, etc.) is received, and a predetermined number of products are sequentially stacked and held on the transfer cart, and in that state, transferred to the shipping destination. Work load is greatly reduced. For example, it is not necessary to use a loading robot or the like that has been conventionally used, and the distribution cost can be greatly reduced.

  Furthermore, since the product is stored in advance in the product shelf for each product category, the efficiency of the picking work can be improved. The product storage containers for storing the picked products are allocated in units of categories, and the picked products are stored in accordance with the allocation. Therefore, the efficiency of the product arrangement work at the shipping destination can be improved.

It is the example schematic which showed the operation | work which displays goods from the goods storage container conveyed by the picking goods conveyance system which concerns on this invention to a goods shelf.

An embodiment of a picking product conveyance system according to the present invention will be described with reference to FIGS.
FIG. 1 is a simplified flow diagram illustrating a picking commodity transport system according to the present invention. In this embodiment, first, in the product storage step, products are stored in advance in a product storage shelf for each category. In this way, the efficiency of picking up products is improved.

  Subsequently, upon receiving an instruction to ship the product, the process proceeds to the first product storage step. In the first product storage step, the picking cart is run, and one of the product storage containers loaded in advance on the cart is removed. The product is placed at a predetermined position on the cart, and a necessary number of products based on the shipping instruction are stored in the product storage container. In addition, the product storage container is allocated for each category of the product to be picked, and the product corresponding to the allocated category is picked.

  Subsequently, after the first product storage step is completed, the process proceeds to the second product storage step. Here, a new product storage container is placed in two layers on the product storage container in which the product is stored in the first product storage step, and a required number of products based on the shipping instruction for another product are stored. It will be stored in the container. The first product storage step and the second product storage step are combined and defined as one picking product storage step.

  In the second product storage step, similarly to the first product storage step, the product storage container is allocated for each category of the product to be picked, and the product corresponding to the allocated category is picked. It will follow. After the picking product storage step is completed, it is determined whether there is another product shipping instruction. If there is a shipping instruction, the process proceeds to the first product storage step again, and the product storage is continued. To go.

  Next, when there is no other product shipping instruction, the product storage container that is two-tiered in the picking product storage step is defined as one transport container group, and this is moved from the rear to the front on the picking cart. By extruding, the process shifts to a transport container group stacking step for stacking onto a transport belt conveyor. Since one conveyance container group consists of two goods storage containers, there exists an outstanding effect that conveyance efficiency improves twice as compared with the case where one goods storage container is stacked.

  Subsequently, in the transport cart loading step, the transport container group stacked by the transport container group stacking step is received on the downstream side of the belt conveyor, and the received transport container group is predetermined on the transport cart. Stack them up and down sequentially. Then, when a predetermined number is loaded, the conveyance carriage is conveyed to the shipping destination in the loaded state.

  Here, the picking product conveyance system according to the present invention will be described in more detail. 2 and 3 show a schematic process of the picking commodity transport system according to the present invention. For reference numerals, 10 is a picking cart, 50 is a product storage shelf, 52 is a product storage container, 54 is a product, 56 is a transport container group, 58 is a belt conveyor, 60 is a loading machine, and 62 is a transport cart. Show.

  In this embodiment, first, as shown in FIG. 2A, one of the product storage containers 52 loaded in advance on the picking cart 10 is assembled and moved to a predetermined position on the picking cart 10. The picking cart 10 is moved toward the commodity storage shelf 50 while being placed. In addition, the product storage shelf 50 stores products for each category, and the product storage container 52 is assigned for each product category.

  Subsequently, as shown in FIG. 2B, the product storage container 52 (category A) in which the product 54 (category A) for which a shipping instruction has been given is picked from the product storage shelf 50 and moved to the predetermined position. The necessary number of items instructed is stored (first product storing step). After storing the product 54 (category A), the product storage container 52 (category A) is closed, and another product storage container 52 (category B) is moved and placed in two layers on top of it. 2 (c), a product 54 (category B) based on another shipping instruction is picked from the product storage shelf 50 and stored in the other product storage container 52 (category B). Second product storage step). The first product storage step and the second product storage step are collectively defined as a picking product storage step.

  Then, it is determined whether there is any other shipping instruction. If there is a shipping instruction, as shown in FIG. 2D, the product 54 (category A, category B) has been stored so far. Slide the stacked product storage containers 52 (Category A, Category B) from the rear to the front, and assemble one of the product storage containers 52 (Category C) loaded in advance on the picking cart 10, It is moved and placed at a predetermined position on the picking cart 10.

  Thereafter, the product 54 (Category C) for which the shipping instruction has been given is picked from the product storage shelf 50, and the required number of items for which the instruction has been placed is stored in the product storage container 52 (Category C) that has been moved to the predetermined position. (Corresponding to the second first product storage step), the second second product storage step is performed again, and the second picking product storage step is completed. In the present embodiment, the case where there is another shipping instruction is shown, but the present invention is not limited to this. Further, the present invention is not limited to categories.

  Next, as shown in FIG. 2E, the two-tiered product storage containers 52 that have been stored in the picking product storage step are defined as one transport container group 56, and the transport container group 56 is picked. By pushing out (sliding) forward from the rear on the carriage 10, it is loaded onto the conveyor belt conveyor 58 as shown in FIG. 2F (conveying container group loading step). In this way, since the two-stage stacked product storage containers 52 are stacked as one transport container group 56, it is usually possible to obtain twice the loading efficiency as compared with the case where one product storage container 52 is stacked. It is connected.

  The transport container group 56 stacked on the transport belt conveyor 58 is processed on the downstream side of the belt conveyor 58 as shown in FIG. 3 (transport cart loading step). Specifically, first, as shown in (a) and (b), the transporting container group 56 is caught by the stacking machine 60 arranged on the downstream side of the transporting belt conveyor 58, and inserted into the machine in advance. It is loaded on the placed transport carriage 62.

  Subsequently, as shown in (c), the transport carriage 62 is lowered to a predetermined height, and another transport container caught by the loading machine 60 in the subsequent process is placed on the transport container group 56 loaded. The group 56 is stacked and stacked. Then, again, as shown in (d), the transport carriage 62 is lowered to a predetermined height, and another transport container group 56 caught by the loading machine 60 in the subsequent process is further stacked on the transport container group 56. To load. After the predetermined number of transport container groups 56 are stacked up and down, as shown in (e) and (f), these transport container groups 56 are released from the stacking machine 60 to the outside together with the transport carriage 62, Thereafter, it is transported to the shipping destination.

  In addition, the product storage shelf 50 in this embodiment is set as a layout corresponding to the product category arrangement of the product shelf in a standard store (shipping destination) as a reference (for example, adjacent category, category arrangement, etc.). It is desirable to store in stock each product that arrives in units.

  In addition, in order to avoid inconsistencies in product category judgments between the delivery source and the delivery destination, the product category code is shared between the two, and the product master's It is desirable to establish a sharing system (EDI).

  By adopting such a process, even in a store having a narrow passage width between product shelves such as a drug store, it is possible to convey the product as it is without sorting or transshipment. In addition, since the product can be transported in the category unit, as shown in FIG. 7, it is not necessary to walk around the product display shelves allocated for each category in the product display work. The product can be efficiently extracted. As a result, it does not interfere with the purchaser's traffic. Furthermore, the process of unloading once in the backyard of the store and transferring it to the cart or the like to carry it in the store can be omitted.

  Here, the details of the picking operation (product storage step) will be described with reference to the drawings. 4A and 4B are views showing an example of a picking cart used in the picking commodity transport system according to the present invention. FIG. 4A is a plan view and FIG. 4B is a right side view.

  Further, 10 is a picking cart, 12 is a frame, 14 is a traveling caster, 16 is a product storage container stacking unit, 20 is a roller member, 21 is a rail member, 22 is a slide member, 23 is a lock piece, and 24 is a slide lever. , 26 is a stopper, 28 is a stopper lever, 30 is an anti-back stopper, 32 is a tip stopper, 34 is a console mounting portion, and 36 is a weight measuring instrument.

  As shown in FIG. 4, the picking cart 10 is first provided with a traveling caster 14 on the lower surface of the frame 12 so that the picking cart 10 can travel freely from the rear to the front and rear. It has become. A product storage container stacking unit 16 is provided on the upper surface of the frame 12 so that a plurality of product storage containers 52 for storing picked products and the like can be stacked.

  Note that the picking cart 10 has a console mounting portion 34 for providing a picking console (not shown) on the rear side of the frame 12, and a product storage container at the lower rear side of the product storage container stacking portion 16. The weight measuring device 36 for measuring the weight of 52 is provided, and the picking console and the weight measuring device 36 prevent erroneous insertion and shipping of the product to be picked and improve the efficiency of picking work. It can be done.

  Subsequently, in the product storage container stacking portion 16 provided in the picking cart 10, the roller member 20 is provided with a pair of left and right along the front-rear direction of the stacking surface of the product storage container 52 as shown in FIG. It is equipped. The roller member 20 can move the product storage container 52 or the transport container group 56 in the front-rear direction of the picking cart 10 in a state of being loaded. For example, when the transport container group 56 that has been picked is moved in the forward direction, it is only necessary to slide on the roller member 20, so that an operation of lifting the transport container group 56 is not necessary, and the burden on the operator is greatly increased. Will be reduced.

  As shown in FIG. 4A, the commodity storage container stacking unit 16 is provided with a slide member 22 attached between a pair of left and right roller members 20. The slide member 22 is slidable in the front-rear direction of the product storage container stacking portion 16 so that the range of the product storage container stacking portion 16 in the front-rear direction can be expanded. That is, for example, when six product storage containers 52 (that is, three transport container groups 56) are loaded, it is necessary to expand the space for picking work. The space can be expanded by sliding the member 22 in the forward direction of the commodity storage container stacking portion 16.

  Further, since the tip stopper 32 can be tilted forward of the product storage container stacking unit 16, it is necessary to lift the transport container group 56 one by one when the transport container group 56 is transferred to equipment such as a belt conveyor. This eliminates the burden on the operator.

Subsequently, a process of picking work (product storage step) using the picking cart 10 in the present embodiment will be described with reference to FIGS. 5 and 6.
Note that the drawing is simplified to some extent. In the following description, the reference numerals in parentheses correspond to the reference numerals in FIGS. 2 and 4, but are not attached to FIGS. 5 and 6. Further, “Oricon” in the drawing is an abbreviation for a folding container, and means the commodity storage container 52 in this specification and the like.

  Furthermore, in the figure, a total of 6 boxes of Oricons are used, each of which is stacked in two stages. This is intended to improve the efficiency of delivery work to the shipping destination and product arrangement work at the shipping destination. If the Oricons are stacked vertically on the product storage container stacking section (16), the conveyor capacity for loading on the belt conveyor can be substantially doubled (Oricon). The bottom surface of 1 is equivalent to one oricon, so that two oricons can be loaded at the same time). However, the present invention is not limited to using 6 boxes of oricons.

  First, inventory allocation and shipping instructions in the order of the location of the merchandise storage shelf are transmitted to the picking console. Then, an instruction for changing the allocation of the product storage container in a category unit (for example, health care product, beauty care product, miscellaneous goods, food, etc.) is transmitted. Further, the allocation of the product storage container by weight × volume and the exchange instruction are also transmitted, and the picking work is performed by folding the product storage container 52 on the product storage container stacking portion 16 of the picking work table 10 so as to correspond to them. Stack 6 in a state.

  Subsequently, as shown in FIG. 5A, the picking cart (10) has the product storage container (52) folded on the product storage container stacking portion (16) (on the roller member). In the assembled state, one is loaded. The assembled first product storage container (52) is locked by a stopper and cannot move forward. From here, picking work is started.

  After the picking product has been stored in the first product storage container (52), as shown in FIG. 5 (b), the stopper lever (28) (denoted as black lever in the description) is moved downward. By pushing, the stopper (26) is released, and the first commodity storage container (52) is slightly moved on the roller member toward the front of the commodity storage container stacking section (16). This is because when the lid of the first commodity storage container (52) is closed, the lid hits the rear of the picking cart at the original position. By doing in this way, packing operation of the product storage container (52) becomes easy.

  After the lid is closed, the first product storage container (52) is again moved to the rear of the product storage container stacking section (16) (on the picking work section side) and locked by a stopper. Subsequently, one of the folded product storage containers (52) is assembled and placed on the first product storage container (52). Then, the picked products are stored in the newly assembled second product storage container (52).

  Next, after storing the product in the second product storage container (52), the lid is first closed as shown in FIG. And the lock | rock by a stopper is cancelled | released and the goods storage container (52) loaded in two steps | paragraphs is moved to the front of the goods storage container loading part (16) in the state. Here, the product storage containers (52) stacked in two stages cannot be moved to the rear of the container stacking portion by passing through the anti-back stopper (30).

  And the product storage container (52) of the folded state is assembled in the state locked by the stopper again, and is loaded behind the product storage container (52). Further, as shown in FIG. 5D, the rest of the folded product storage container (52) is placed on the product storage container (52) stacked in two stages, and the product storage container stacking unit (16 ) And the picked product is stored in the third product storage container (52). Here, if an anti-back stopper is provided separately, it is possible to prevent the product storage container (52) loaded in the forefront of the product storage container stacking portion (16) from moving backward.

  Next, after the product is stored in the third product storage container (52), as shown in FIG. 6 (e), the stopper is unlocked as in the first product, and the third product is stored. The storage container (52) is slightly moved on the roller member toward the front of the product storage container stacking section (16).

  After closing the lid, the third commodity storage container (52) is moved to the rear of the commodity storage container stacking section (16) again and locked by a stopper. Subsequently, one of the folded product storage containers (52) is assembled and placed on the third product storage container (52). Then, the picked products are stored in the newly assembled fourth product storage container (52).

  Next, after storing the product in the fourth product storage container (52), the lid is first closed as shown in FIG. 6 (f). And the lock | rock by a stopper is cancelled | released and the goods storage container (52) loaded in two steps | paragraphs is moved to the front of the goods storage container loading part (16) in the state. Here, the product storage containers (52) loaded in two stages cannot be moved to the rear of the product storage container stacking section (16) by passing through the anti-back stopper (30).

  And the product storage container (52) of the folded state currently loaded on the 2nd product storage container (52) is assembled in the state locked by the stopper (26) again, and the product storage container loading part ( 16) The products picked up in the fifth product storage container (52) are stored in the rear of 16).

  After the product is stored in the fifth product storage container (52), the lock by the stopper is released as in the first, and the fifth product storage container (52) is placed on the roller member on the product storage container. Although it is necessary to move a little toward the front of the loading unit (16), in this state, the product storage container (52) is already loaded on the stacking unit (40) of the product storage container. I can't let you.

  Therefore, as shown in FIG. 6G, first, the slide member (22) is slid toward the front of the product storage container stacking portion (16). By doing so, the range in the front-rear direction of the product storage container stacking portion (16) can be expanded. After sliding the slide member (22), the respective product storage container stacking sections (16) stacked in two stages are moved in the forward direction of the product storage container stacking section (16).

  Subsequently, the lock by the stopper (26) is released, and the fifth product storage container (52) is moved slightly toward the front of the product storage container stacking section (16) on the roller member (20), Close the lid.

  After closing the lid, the fifth product storage container (52) is again moved to the rear of the product storage container stacking section (16), locked by the stopper (26), and the slide member (22) is moved back to the original position.
