Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seaweed bundle conveying device for recovering a seaweed bundle of which the posture has been collapsed among the seaweed bundles conveyed from a counter to a folding machine.

[0002]

2. Description of the Related Art Sheet-shaped seaweed produced by a dry seaweed production device is counted by a device called a counter by a predetermined number (usually 10), and the 10 seaweeds are stacked to form a seaweed bundle, This seaweed bundle is sent to a folding machine by a conveyor, folded in two and folded, and the folded seaweed bundle is bundled by a binding machine and shipped to the market.

Nowadays, the counter, the folding machine, and the binding machine have been widely spread, and a series of operations from the production of dry seaweed by the dry seaweed production apparatus to the binding of the seaweed bundle by the binding machine are performed as follows.
A considerable part of it is automated.

[0004]

As described above, nori seaweed is stacked in a predetermined number and carried out from the counter as a seaweed bundle and sent to the folding machine by a conveyor. Some of them are not always neatly stacked, and their posture is broken. As the collapse of this posture, there is a lateral shift or a transport direction shift.

However, conventionally, there is no means for detecting and removing the seaweed bundle whose posture has collapsed, so the seaweed bundle whose posture has collapsed is sent to the folding machine as it is, folded in two, and then bound by the binding machine as it is. It had been. However, since the seaweed bundles thus bundled with their postures broken cannot be shipped to the market, the worker visually inspects them after binding, and if they are defective, they are properly aligned and reassembled. The person was forced to do a great deal of work.

[0006] Therefore, the present invention provides a transport device for laver bundles which can select and remove only non-defective products from the counter from the counter to the folding machine and remove the ones whose posture has been lost. The purpose is to do.

[0007]

To this end, the present invention is directed to a conveyor 11 for conveying a bundle of seaweed, a pair of left and right first sensors 22 for detecting seaweed that is spilled out from the conveyor 11 to both sides. A second sensor 24 for detecting the length of the seaweed bundle M conveyed on the conveyor 11 in the direction of conveyance, and detection signals of the first sensor 22 and the second sensor 24. On the basis of the above, the transport device for the seaweed bundle is constituted by the transport path switching means for switching the transport path for the seaweed bundle M to the collecting section 10 side.

[0008]

According to the above construction, since the first and second sensors 22 and 24 can detect the seaweed bundle M whose posture has collapsed, and remove this, the seaweed bundle M of good quality in which the posture has not collapsed.
Only the folding machine 2 can be sent.

[0009]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a side view of a transport device for a laver bundle, and FIG. 2 is a front view of the same. In FIG. 1, 1 is a counter and 2 is a folding machine. Counter 1 counts the number of non-defective products by selecting and removing defective products such as tears and perforations from the sheet-like seaweed produced by the dry seaweed production equipment.
A sheet of seaweed m is stacked and carried out as a seaweed bundle M. Further, the folding machine 2 folds and folds the seaweed bundle M sent from the counter 1, and sends it to the next binding machine. The counter 1 and the folding machine 2 are well-known devices.

Between the counter 1 and the folding machine 2, a seaweed bundle conveying device described below is provided. Reference numeral 11 is a first conveyor, 12 is a second conveyor, and 13 is a third conveyor. These conveyors 11, 12 and 13 are belt conveyors and convey the seaweed bundle M from the counter 1 to the folding machine 2. The collection box 10 is installed below the second conveyor 12.

FIG. 3 is a plan view of a connecting portion between the second conveyor 12 and the third conveyor 13. The pulley 14 of the second conveyor 12 and the pulley 15 of the third conveyor 13 are mounted on the same rotating shaft 16. A sprocket 17 is attached to the end of the rotary shaft 16. This sprocket 17
A chain 20 is stretched over a sprocket 19 mounted on the rotary shaft of the motor 18. Therefore, the motor 18
Is rotated forward, as shown by the chain line in FIG.
The conveyor 12 rotates upward to open the transport path. When the motor 18 rotates in the reverse direction, the second conveyor 12 rotates in the reverse direction and returns to the original posture. In each figure, a transmission system such as a motor for rotating the conveyors 11, 12, 13 and a frame for supporting the conveyors 11, 12, 13 are omitted.

In FIG. 1, a frame 21 is installed on the first conveyor 11. As shown in FIG. 2, the frame 21 is a gate type installed on the first conveyor 11, and the touch-type first sensor 2 is provided on both sides of the upper surface thereof.
Two left and right pairs are provided. The lever 23 of the first sensor 22 hangs on both sides of the first conveyor 11. The second sensor 24 is provided at the center of the upper portion of the frame 21.
Is provided. The second sensor 24 is an optical sensor and detects the seaweed m transported on the first conveyor 11.

FIG. 4 is a block diagram of the control circuit. The two first sensors 22 and the second sensors 24 are the control unit 2
Connected to 5. The control unit 25 uses these sensors 2
It receives the output signals of 2, 24 and controls the motor 18 and controls the entire apparatus.

The transport device for this seaweed bundle is constructed as described above, and its operation will be described below. In FIG.
The seaweed bundle M carried out from the counter 1 is sequentially conveyed through the first conveyor 11, the second conveyor 12, and the third conveyor 13, and is sent to the folding machine 2. 5, 6 and 7 are the first
The top view of the seaweed bundle M conveyed by the conveyor 11 of FIG. The seaweed bundle M shown in FIG. 5 is parallel to the conveyor 11 and is conveyed in a correct posture. This seaweed bundle M is a good product, and includes the second conveyor 12 and the third conveyor 1.
It is sent to the folding machine 2 through 3.

The nori bundle M shown in FIG. 6 is laterally displaced and largely protrudes to both sides of the first conveyor 11. Therefore, this seaweed bundle M hits the lever 23 of the first sensor 22 and it is detected that the posture is collapsed. Then, the output signal of the first sensor 22 is input to the control unit 25, and the control unit 25 drives the motor 18 to rotate the second conveyor 12 upward as shown by the chain line in FIG. Then, the seaweed bundle M sent from the first conveyor 11 falls into the collection box 10 and is collected. After a lapse of a predetermined fixed time, the motor 18 is driven in reverse and the second conveyor 12 returns to its original position. That is, the second conveyor 12, the motor 18, the control unit 25, and the like are a transport path switching unit that switches the transport path of the seaweed bundle M.

FIG. 7 shows that the laminated seaweed m is Δ in the conveying direction.
The case where L shifts is shown. The second sensor 24 is
The tip a of the seaweed bundle M conveyed on the first conveyor 11
And the end portion b is detected. The transport speed of the first conveyor 11 is known, and therefore the control unit 25 calculates the length L ′ of the seaweed bundle M in the transport direction from the detection timing of the leading end a and the end b and the transport speed. The length L of the seaweed m is known, and if the deviation amount ΔL (L′−L) is equal to or greater than the allowable value, the control unit 25 determines that there is a deviation in the transport direction, and in this case also, the second conveyor. The laver bundle M is dropped into the collection box 10 and collected by rotating 12 upward. The seaweed m collected in the collection box 10 is manually arranged into 10 sheets and sent to the folding machine 2.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the conveying path is switched by rotating the second conveyor 12 upward, and the defective seaweed bundle M is moved downward. Although it is collected in the collection box 10, the point is that the defective seaweed bundle M should not be carried into the folding machine 2. Therefore, it is not limited to the collection box 10 below, and the conveyance path may be located above or below. The defective seaweed bundle M may be collected by switching to the side, and the specific configuration of the transport path switching means for collecting the defective seaweed bundle M is not limited to this embodiment. In the above embodiment, the second sensor 24 detects the seaweed bundle M from above, but it may detect it from below.

[0018]

As described above, according to the present invention, in the seaweed bundle M sent from the counter 1 to the folding machine 2, a defective product whose posture is collapsed can be automatically detected and removed. Only the bundle M can be sent to the folding machine 2 to be folded.
