Next, the operation of the pallet with rollers of the present invention will be explained.

The pallet 1 with rollers is supplied in advance onto the pallet supply conveyor 37 and is on standby, and the pallet 1 is loaded onto the main body of the stacking machine.

When it is detected by an appropriate detector (not shown) that there is no pallet with rollers 1 on the roller conveyor 25 located below the roller conveyor 11, the roller conveyor 25 is driven by the driving device 30, and the pallet with rollers 1 is fed. 1
737 onto the roller conveyor 25, and when the pallet with rollers 1 is positioned at a predetermined position on the roller conveyor 25, this is detected and the drive device 30 is stopped.

A signal indicating that the pallet with rollers 1 is in a predetermined position is sent to the cylinder 33 as well as to the drive device 30 described above.

When the pallet with rollers 1 is sent onto the roller conveyor 25, the cylinder 33 is extended, and the arm 35 is positioned diagonally upward as shown by the two-dot chain line in FIG. However, when the cylinder 33 receives a signal, the rond shortens, the pin 34 descends while being guided by the guide groove 36, and the arm 35 stands upright. The bracket 40 of the lattice-shaped holding plate 9 is pressed down (see the solid line state in FIG. 11).

Then, the pressing plate 9 overcomes the force of the spring 6 and causes the friction plate 8 to descend, and the contact between the friction plate 8 and the roller 4 is released, so that the free roller 4 becomes freely rotatable.

When the arm 35 is lowered to its lower limit, the signal is sent to the skit pushing conveyor 39 to drive the skit pushing conveyor 39.

Then, skit 1 with two-wheeled vehicles such as motorcycles
0 is pushed from the skit pushing conveyor 39 to a predetermined position on the 7-ree roller 4 of the pallet with rollers 1.

When pushing the skit 10, the pushing arm 24
Although the lower end of the pushing arm 24 interferes with the upper surface of the skit 10, the pushing arm 24 is pushed by the skit 10 and rotates forward, and as soon as the skit 10 passes, it becomes straight as shown by the solid line in FIG.

When the skit 10 is pushed into a predetermined position on the free roller 4 of the pallet with rollers 1, the signal is transmitted to the drive device 12.
The drive device 12 is activated.

Then, power is transmitted to the chain 19 in the order of sprocket 13, chain 17, sprocket 16, shaft 15, and sprocket 18, and the chain 19 rotates to move the pushing arm 24, and the lower end of the pushing arm 24 moves to the skid 10. , and push the skit 10 from the A side to the predetermined position on the B side in FIG.

When the skit 10 is pushed to a predetermined position, the drive device 12 rotates in the opposite direction and the pushing arm 24 returns to its original position, and the skit pushing conveyor 39 is driven to push the next skit 10 onto the free roller 4 at the A position. Then, the pushing arm 24 is driven, and the skit 10 is pushed onto the free roller 4 on the B side by the pushing arm 24.

The skits 10 are sequentially placed on the free roller 4 as described above, but the pushing position of the skit 10 from the entry side to the B side is controlled by storing the rotational speed of the shaft 15 in a shaft encoder, ball memory, etc. Do it sequentially or
Alternatively, a stopper supported from F, L, etc. is provided at the end of the pallet with rollers 1 on the side opposite to the input side of the skit 10, and after confirming that the skit 10 has completely interfered with the stopper, the next operation can be started. Let it come in.

Skit 10 is on free roller 4 of pallet with rollers 1
When it is full, operate the cylinder 33 to extend the rond, and then move the arm 35 and the bracket 4 of the holding plate 9.
Disengage from 0.

Then, the friction plate 8 and the pressing plate 9 are pushed upward by the force of the spring 6, and the surface of the friction plate 8 comes into contact with the lower surface of the free roller 4, so that the free roller 4 becomes non-rotatable.

The holding plate 9 of the pallet with rollers 1 is disengaged from the arm 35, and the free roller 4 rotates.

When the state is reached, the drive device 3 receives the signal and starts the drive device 3 again.
0 is activated and the roller conveyor 25 is driven 1, so the roller pallet 1 on which the skit 10 is placed is sent to the next process via the downstream conveyor 38.

Therefore, the pallet with rollers can perform both the original function of the pallet and the function of a conveying device.

In the embodiment of the present invention, the case where the skits are pushed one by one onto a pallet with rollers has been described, but on the skit pushing conveyor.

It is also possible to prepare one pallet of skits and push the skits onto a pallet with rollers at a time, and the bracket to which the free rollers are attached can be constructed as one piece, and by appropriate means. It can be carried out without a lattice-like holding plate if it is made to descend, the free rollers are arranged in four rows of short ones, but it can also be carried out with one row of long ones, and the base of the pallet The fork of a forklift can be inserted into the skit, the objects to be carried on the skit are not limited to two-wheeled vehicles such as motorcycles, and other suitable objects can be placed on the skit, and other gist of the present invention. Of course, various changes may be made without departing from the above.

Since the roller-equipped pallet of the present invention has the above-described configuration, (1) it is useful for saving labor and manpower, and the work can be carried out safely and reliably.

■) Since the products are stacked on pallets on a flat surface, the operation is smooth, there is no damage to the products, and furthermore, it saves power.

■) The free rollers on the pallet are braked except when pushing the skit, so the load can always remain stable.

etc., exhibits various excellent effects.
