A holding device 21 is attached to the side of the frame 16 for holding down a pallet 28, which will be described later, and for releasing the contact between the free roller 31 and the friction plate 35.

As shown in detail in FIG. 11, the holding device 21 includes a bracket 22, a cylinder 23 pivotally connected to the bracket 22,
It consists of a pin 24 attached to the tip of a cylinder 23 and an arm 25, and the pin 24 is slidably fitted into a guide groove 26 having an appropriate radius of curvature provided on the side of the bracket 22.

On the entry side of the roller conveyor 15, a pallet supply conveyor 2 is provided for feeding pallets 28 onto the roller conveyor 15.
Place 7.

The pallet 28 is shown in detail in FIGS. 5 to 10, and has an appropriate number of free rollers 31 pivotally attached to an appropriate number of brackets 30 erected on a base 29, and each free roller 3
An angle iron guide 32 is disposed on the base 29 at the bottom of the spring 33, and the spring 33 has its lower end supported by the guide 32.
A frame 34 shaped like an angle iron is attached to the upper end of the frame 34, and a friction plate 35 such as a rubber plate is fixed onto the frame 34.

A lattice-shaped holding plate 36 is placed on the friction plate 35 and extends in the front, rear, right and left directions in the gap between the brackets 30, and when the skit 37 is not placed on the pallet 28, the spring 33 is placed on the friction plate 35. acts on the frame 34 and the friction plate 35.
is pushed upward, and the upper surface of the friction plate 35 comes into contact with the downward direction of the free roller 31, preventing the free roller 31 from rotating. In this case, the pressing plate 36 is also pushed up by the spring 33. Although it is
Its upper end is located below the upper surface of the free roller 31.

In addition, 38 in the figure is the skit 3 placed on the pallet 28.

When an appropriate detector (not shown) detects that there is no pallet 28 on the roller conveyor 15 on the lower blade of the stacking machine main body 1, the roller conveyor 15 is driven by the driving device 20, and the pallet 28 is fed into the pallet. conveyor 27
When the pallet 28 is fed onto the roller conveyor 15 and positioned at a predetermined position on the roller conveyor 15, this is detected and the drive device 20 is stopped.

The signal that detects that the pallet 28 is in a predetermined position is
It is sent to the cylinder 23 at the same time as the above-mentioned 1 drive device 20.

When the pallet 28 is sent onto the roller conveyor 15, the cylinder 23 is extended, and the arm 25 is positioned diagonally upward, as shown by the two-dot chain line in FIG. However, when the cylinder 23 receives a signal, the rondo is shortened, the pin 24 is guided by the guide groove 26 and lowered, and the arm 25 stands upright and touches the grid-shaped holding plate. 36 bracket 40 (see solid line state in FIG. 11).

Then, the pressing plate 36 overcomes the force of the spring 33 and causes the friction plate 35 to descend, and the contact between the friction plate 35 and the free roller 31 is released, so that the free roller 31 can freely rotate.

When the arm 25 reaches the lower limit, the signal is sent to the skit pushing conveyor 39, and the skit pushing conveyor 36 is driven seven times.

Then, skit 3 with two-wheeled vehicles such as motorcycles

is pushed to a predetermined position on the free roller 31.

When pushing the skit 31, the pushing arm 14
Although the lower end of the pushing arm 14 interferes with the upper surface of the skit 37, the pushing arm 14 is pushed by the skit 37 and rotates forward, and as soon as the skit 37 passes, it becomes straight as shown by the solid line in FIG.

When the skit 37 is pushed into a predetermined position on the seven-lead roller 31 of the pallet 28, the signal is sent to the drive device 2, and the drive device 2 is activated.

Then, power is transmitted to the chain 9 in the order of sprocket 3, chain 7, sprocket 6, shaft 5, and sprocket 8, and the chain 9 rotates to move the pushing arm 14, and the lower end of the pushing arm 14 moves to the skid 37. , and push the skit 31 from side A to a predetermined position on side B in FIG.

When the skit 37 is pushed to a predetermined position, the drive device 2 rotates in the opposite direction, the pushing arm 14 returns to its original position, and the skit pushing conveyor 39 is driven to push the next skit 37 onto the free roller 31. Then, the pushing arm 14 is driven, and the skit 37 is pushed onto the free roller 31 on the B side by the pushing arm 14.

As described above, the skits 37 are sequentially placed on the free roller 31, but the pushing position of the skits 37 from the entry side to the B side is controlled by storing the rotational speed of the shaft 5 in the shaft encoder, pole memory, etc. Do it sequentially or
Alternatively, a stopper supported from F-L etc. is provided at the end of the pallet 28 on the opposite side to the entry side of the skit 37, and the next operation is started after confirming that the skit 37 has completely interfered with the stopper. Make it.

When the top of the 7-ree roller 31 of the pallet 28 is filled with skits 37, the cylinder 23 is operated to extend the rondo, and the arm 25 and the bracket 40 of the holding plate 36 are moved.
Solve the tomeboai.

Then, the friction plate 35 and the pressing plate 36 are pushed upward by the force of the spring 33, and the friction plate 35 is pushed upward by the force of the spring 33.
The surface of the free roller 31 comes into contact with the lower surface of the free roller 31, so that the free roller 31 does not rotate.The holding plate 36 of the fourth pallet 28 is disengaged from the arm 25, and the free roller 31 becomes non-rotating. When the drive device 20 receives the signal, the drive device 20 is activated again, and the roller conveyor 15 is activated again.
is driven, so pallet 2 on which skit 37 is placed
8 is sent to the next process via the downstream conveyor 38.

Therefore, the pallet 28 can perform both the original function of the pallet and the function of a conveying device.

In the embodiment of the present invention, a case has been described in which skits are pushed onto pallets one by one.
It is also possible to push the skit onto the pallet at once, the arm for pushing the skit can be of the type installed on the conveyor rather than the hanging type, and it is possible to install a free roller. The present invention can be implemented even without a grid-like holding plate by constructing the bracket as a whole and lowering it by an appropriate means;
The free rollers are arranged in four rows of short ones, but it can also be implemented with one row of long ones, and it is also possible to insert the fork of a forklift into the base of the pallet. Items to be placed on the skit It goes without saying that the device is not limited to two-wheeled vehicles such as motorcycles, and that appropriate objects can be placed thereon, and that various other changes can be made without departing from the gist of the invention.
