Description

  The present invention relates to a supply conveyor for supplying articles toward a film in a horizontal bag making and filling machine.

  The horizontal bag making and filling machine includes a supply conveyor that conveys articles at predetermined intervals toward a cylindrical film formed into a cylindrical shape by bag making means. This supply conveyor is provided with a transport body in which push members for pushing articles are arranged at predetermined intervals on an endless chain wound around a sprocket that is separated in the front and rear directions in the transport direction. When packaging articles with different length dimensions due to changes in packaging varieties, etc., when it is necessary to change the arrangement interval of the pusher member with respect to the endless chain in the conveyance body, the conveyance body has the desired arrangement interval. It is exchanged with the carrier. In addition, since the supply conveyor is in direct contact with the article, especially for packaging of food, etc., the supply conveyor with which food is in direct contact is required to maintain a sanitary condition from the viewpoint of hygiene. The entire conveyor, including the frame of the conveyor and other structures, is removed from the conveyor as necessary, and the entire conveyor is cleaned and cleaned with alcohol, water, or the like.

  In the maintenance work such as the replacement and cleaning of the transport body described above, when the transport body is removed from the supply conveyor, it is generally performed by dividing the endless chain of the transport body wound around the sprocket. However, since the work of attaching and detaching the endless chain takes time, an apparatus disclosed in, for example, Patent Document 1 has been proposed to deal with these problems. In this device, one sprocket around which an endless chain is wound is moved closer to the other sprocket by the operation of the air cylinder to loosen the endless chain, and the chain rail that supports the endless chain from below is lowered. By being separated from the endless chain, the endless chain can be removed from the apparatus laterally without being divided.

Synchronous phase matching control such as an end seal mechanism can be made appropriate.

(Effects of Example)
Next, the operation of the supply conveyor of the horizontal bag making and filling machine according to the above-described embodiment will be described.

When the transport body 14 is removed from the main body 10, as shown by a two-dot chain line in FIG. 6, the end cover 72 is lifted and rotated upward about the hinge 74 to the open position on the back side. By making it face, the open portions T ₃ , T ₁ , T ₄ on the upper side, the near side, and the upstream side of the first driven sprocket 28 that becomes the upstream turning portion of the transport body 14 are opened at a time. Further, the article guide 46 and the supply bed 12 are rotated toward the back side or the near side around the hinges 64 and 20, respectively, so that the article guide 46 and the supply bed 12 face the open position. all of the upper opening portion T ₃ is opened. Further, the front side cover 68 on the front side is rotated upward so that the lower end portion is lifted toward the front side with the hinge 70 as the center, and is brought into the open position, so that the lower side open portion T on the lower side of the front side wall 18 is reached. ₂ is opened (see FIG. 4).

Next, by rotating the operation handle 44 and operating the adjusting means 26, the first driven sprocket 28 is moved downstream to sufficiently loosen the endless chain 22 until it can be removed. Then, the endless chain 22 is removed from the tooth portions of the sprockets 28, 30, 32 of the upstream turning portion and the downstream turning portion and moved to the front side, and the upper opening portion T ₃ in the opened state of the main body portion 10 is left as it is. It can be removed from the main body 10 to the near side through the lower opening T ₂ and the side opening T ₁ .

  Note that the front side cover 68 on the front side can be kept stationary at an arbitrary opening angle position, so that the operator needs to work while holding the front side cover 68 in the open position when the transport body 14 is detached. No, the workload can be reduced.

As described above, the endless chain 22 is loosened by the adjusting means 26, and the supply bed 12, the article guide 46, the front side cover 68, and the end cover 72 are rotated to open the open portions T ₃ , T ₂ ,. it is possible to desorb the carrier 14 by opening the T _1, without employing a complicated configuration, such as providing the power source, the working of the desorption cleaning or carrier 14 of the feed conveyor of a tool It can be set as the simple structure which can be performed by an operator's manual operation without doing all. Further, the conveyor covers for opening and closing each of the open portions T ₃ , T ₂ , T ₁ , the supply bed 12 for the article guide, the article guide 46, the front side cover 68, and the end cover 72 can be rotated to the main body. Therefore, there is no need to remove or attach the supply bed 12, the article guide 46, the front side cover 68, and the end cover 72 from the main body or the like when the transport body 14 is detached or the inner surface of the covers is cleaned. The workload can be reduced.

  The adjusting means 26 can operate the handle 44 at a position protruding outward from the upstream end of the main body 10, so that the operation handle 44 has good operability, and the endless chain 22 is wound around the first driven sprocket 28. Since it is located on the back side from the upstream turning portion to be hung, it becomes a hindrance when detaching the transport body 14 from the front side, so that it does not take time for the detachment work.

  When the transport body 14 is detached, the front supply bed 12, the front article guide 46 and the front side cover 68 located on the front side of the transport body 14 are endless chains in which any surface is detached at an open position rotated 90 degrees or more from the closed position. The posture does not face 22. That is, in the front supply bed 12 and the front article guide 46 positioned on the upper side of the front side wall 18 in the closed position, each surface faces downward in the open position, so that the inner surface faces the chain when the endless chain 22 is detached and closed. In the front side cover 68 positioned below the front side wall 18 in the formation position, the inner surface faces the chain when the endless chain 22 is attached / detached because the surface faces upward in the open position, and the front supply bed 12 and the front article guide. Even when the endless chain 22 moving in the vertical space of the front and rear side covers 68 and the front side cover 68 comes into contact, the oil content of the chain 22 adheres to the front supply bed 12, the front article guide 46, and the front side cover 68. Can be prevented. Further, since the inner side which is the inner surface in the closed position can be set to the front side when opened, the main body portion 10 of the supply conveyor in the cleaning operation of the inner surfaces of the supply bed 12, the article guide 46 and the front side cover 68. There is no need to remove it from the machine, reducing the workload and speeding up the maintenance work.

  After the transport body 14 that has undergone maintenance such as cleaning is wound around the sprocket group, the endless chain 22 is stretched by rotating the operation handle 44, and the supply bed 12 and the article guide 46 are reversed. Then, the front side cover 68 and the end cover 72 are turned to the closed position to enable operation.

  By running the transport body 14 in the operable state, a signal obtained by detecting the pushing member 34 by the detecting means 76 is stored as an origin position signal of the transport body 14, and the origin signal is used in the packaging machine. Synchronous phase matching control between each operation mechanism such as a film feed mechanism and an end seal mechanism and the supply conveyor is performed. That is, every time the carrier 14 is detached or attached, synchronization phase alignment is performed, so that operations such as positioning the pushing member 34 at a predetermined position and performing synchronization phase alignment are unnecessary. It is possible to easily deal with operations up to restarting operation.
