(Example) Hereinafter, illustrated embodiments of the present invention will be described.

As shown in Figures 1 to 4, the pallet main body 1 forms a box-shaped frame, and on the upper surface side of the box-shaped frame, two narrow plates are provided on both sides to form the upper plate 2. . A rubber sheet 2a is attached to the upper surface of the upper plate 2 to protect the gauge plate 3.

A gauge plate guide member 4 made of a hard elastic material such as hard rubber is attached to the outer edge of the upper plate 2 to roughly position the gauge plate 3 when it is placed on the upper plate 2. The opening formed between each upper plate 2 is
It has a function to release attached parts of the gauge plate 3 such as nails.

The height of the pallet body 1 is such that the height of the side plate 6 provided between the top plate 2 and the bottom plate 5 is higher than the nails, bands, accessories, back mechanism parts, etc. attached to the gauge plate 3. This ensures the height necessary to prevent parts attached to the gauge plate 3 from hitting the bottom plate 5 when the gauge plate 3 is placed. The side plate 6 is fixed slightly inside the edges of the top plate 2 and the bottom plate 5 to make it easier to grip the edge of the gauge plate 3 placed on the top plate 2. A contact member 7 made of a hard elastic material such as hard rubber is fixed to the surface of both ends of the side plate 6 located in the front-rear direction with respect to the traveling direction of the pallet body 1 from the inside. A shock absorber 8 is projected from the lower center of the front side plate 6, and an absorber abutting member 9 is provided at the shock absorber contact position below the center of the rear side plate 6. Contact member 7

Below the position where the shock absorber 8 and the shock absorber abutting member 9 are provided, a stopper (not shown) provided on the conveying device side is in contact with a stopper (not shown).
A notch 10 for operating the stopper is provided on the bottom plate 5.
to form. Pallet position detection holes 12 are provided in at least two diagonal positions among the four corners of the bottom plate 5.
to be drilled.

At the end of the pallet upper plate 2, holes are provided at least at two diagonal positions in the four corners of the pallet body 1, to allow the gauge plate positioning shaft 13 to pass through, avoiding the positions where the pallet position detection holes 12 are drilled. 14 is drilled. 15 is a support member attached to the upper plate 2;
The support member 15 is provided with a sliding hole through which the gauge plate positioning shaft 13 is slidably inserted, and this sliding hole is arranged coaxially with the hole 14. As shown in FIG. 5, the gauge plate positioning shaft 13 is provided with a groove 16 on its circumferential surface in the center and a collar 17 on its lower end to prevent it from falling off. In normal operation, the gauge plate positioning shaft 13 is held in the sliding hole so that its upper end does not protrude from the hole 14, and its lower end faces directly above the through hole 26. Further, a spring means, which will be described later, is brought into contact with the outer periphery of the gauge plate positioning shaft 13. This spring means mainly consists of a coil spring 19 and a sphere 20. A hole 18 is formed in the side surface of the support member 15, and a coil spring 19 and a coil spring 1 are inserted into the hole 18.
Insert the ball 20 which is biased by the spring toward the gauge plate positioning shaft 13 through the hole 18 by screwing the blind cover 21 together.
Put a lid on it. The position of the groove 16 of the gauge plate positioning shaft 13 is such that the tip of the gauge plate positioning shaft 13 protrudes above the pallet upper plate 2 when the sphere 20 is pushed into the groove 16 and fixed in position. . The spring force of the coil spring 19 is such that when an axial force is applied to the gauge plate positioning shaft 13, the sphere 20 retracts, and when the gauge plate positioning shaft 13 slides and the groove 16 comes to the position of the hole 18. sphere 2
0 into the groove 16.

The spring means may have another embodiment as shown in FIG. A collar 22 is provided approximately at the center of the gauge plate positioning shaft 13, and a spring storage hole 23 is provided in the axial direction in the support member 15 to accommodate the coil spring 2.
4 and 25 are installed around the outer periphery of the gauge plate positioning shaft 13 with the collar 22 in between, and a blind cover is screwed onto the open side of the spring storage hole 23, so that the gauge plate positioning shaft 13 is always connected to the coil springs 24 and 25. Position it so that the spring forces are balanced.

A through hole 26 is bored in the bottom plate 5 at the lower part of the mounting position of the gauge plate positioning shaft 13, and the gauge plate positioning shaft 13 is passed through a projecting member (not shown) that pushes up a rod or the like from below the pallet body 1. It can be so.

In this embodiment, when the product is placed on a conveyor (not shown) with the shock absorber 8 side facing forward and conveyed, the product is transported in a fixed direction until the stopper 5 provided on the conveyor side comes into contact with the notch 10 of the bottom plate 5. is,
When the pallet body 1 is close enough to contact the pallet body 1 located in front, the shock absorber 8 hits an absorber abutting member 9 provided on the pallet body 1 in the front to reduce the impact. At this time, the distance between the two pallet bodies 1 is regulated by the abutting member 7 so that the distance does not become narrower than necessary, thereby preventing accidents such as the operator's hands being caught. Palette body 1
When the pallet comes into contact with the stopper and stops, a pallet positioning member (not shown) installed on the conveyor side rises and is inserted into the pallet position detection hole 12, fixing the pallet body 1 at a predetermined position on the conveyor side. . If the pallet is in the working position, after fixing the position of the pallet main body 1, immediately attach the accessories or back mechanism parts, if the pallet is in the gauge plate mounting position, place the gauge plate 3 on the pallet, and if the gauge plate is in the reverse position, then attach it immediately. Then, the gauge plate 3 is turned over, and if it is at the gauge plate take-out position, the gauge plate 3 is taken out from above the pallet. When placing the gauge plate 3 at the gauge plate mounting position, place it so that the gauge plate positioning shaft 13 is inserted into the positioning hole drilled in the gauge plate 3, and adjust the mutual position of the pallet body 1 and the gauge plate 3. Confirm. At this time, if necessary, the raised member provided on the conveyor side is raised, and the lower end surface of the gauge plate positioning shaft 13 is pushed by the raised member passing through the through hole 26, so that when the gauge plate 3 is placed. Either the gauge plate positioning shaft 13 is prevented from descending due to the load, or the gauge plate positioning shaft 13 is more actively pushed up and inserted into the gauge plate side positioning hole (not shown). Such positioning is possible because the lower end of the gauge plate positioning shaft 13 faces the through hole 26, so that the protruding member can be aligned with the pallet body 1.
When the gauge plate positioning shaft 13 is inserted into the through hole 26 from below and the gauge plate positioning shaft 13 is pushed up, the upper end portion of the gauge plate positioning shaft 13 protrudes from the upper plate 2 . By engaging the upper end of the protruding gauge plate positioning shaft 13 with the gauge plate 3, the gauge plate 3 and the pallet body 1 can be easily positioned. That is, since there is no need to provide a large-scale device to push up the gauge plate positioning shaft 13, the overall configuration can be simplified.

Further, during the above positioning, the coil spring 19 pushes the sphere 20 into the groove 16 and engages it,
The upper end of the gauge plate positioning shaft 13 is held in a state in which it protrudes from the upper plate 2. Thereby, the spring means maintains the positioning state of the pallet body 1 and the gauge plate 3, so that the production work of the gauge plate 3 can be performed satisfactorily. Since there is no need to provide any special device other than the spring means to maintain the positioning, the overall configuration can be simplified. Furthermore, during the production work of the gauge plate 3, the opening allows the attached parts of the gauge plate 3 to escape, thereby preventing damage to the attached parts.

In this way, in the above embodiment, the relative position between the gauge plate 3 and the pallet body 1 is determined, and then the conveyor is fixed at a specified position, so the working position is determined and the work content of the operator is adjusted to the gauge plate. The work can be limited to attaching accessories and functional parts to the surface. This reduces the chance of damage to both the gauge plate and the operator.

Furthermore, automatic conveyance of the pallet body 1 becomes possible, and the positioning of the gauge plate placed on the pallet body 1 can be performed mechanically, making automation of work easier. Furthermore, the pallet body 1 is automatically conveyed, increasing the work efficiency of assembly line work.
It is possible to improve productivity and allow workers to concentrate on installing accessories, etc.

(Effects of the invention) As described above, the present invention positions the gauge plate on the pallet using the gauge plate positioning shaft, and locks the pallet positioning member on the conveyor side by drilling holes for pallet position detection in the pallet bottom plate. The pallet can be positioned on the conveyor easily and inexpensively using a device with a simple structure, and the openings at the top of the pallet body prevent damage to the parts already attached to the gauge plate. , it becomes possible to change the conveyance work from manual work to automatic conveyance, and direct conveyance of gauge plates can be replaced by conveyance of pallets. Therefore, there is no need to directly handle gauge plates having various protrusions during transportation, and by handling pallets, the same effect as when handling gauge plates can be obtained, and both the gauge plates and the operator can be protected. Furthermore, there is no need for transport work, and the worker can concentrate on attaching accessories or back mechanism parts, increasing work efficiency and productivity.
