Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a tire shelf for loading tires stacked in, for example, 6 to 8 stages (hereinafter simply referred to as stacked tires) into a shelf pallet. This relates to a stacking device.

(Problems of the Prior Art to be Solved by the Invention) Conventionally, each stacked tire is loaded into a shelf pallet while being compressed in the stacking direction by hand or by a forklift equipped with a clamp arm. The problem was that the loading work required a great deal of effort, time, and skill.

(Purpose of the Invention) The present invention was devised to solve the above-mentioned conventional problems, and is an automation system that enables mechanical shelving work by simply feeding stacked tires upright onto a roller conveyor. The purpose of this invention is to provide an effective tire rack stacking device.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In the tire racking device of the present invention, the shelf pallet 4 is laid down horizontally, and the stacked tires M are inserted between the parallel longitudinal members 2 of the shelf pallet 4 while being compressed in the stacking direction. It is a device that is interposed and stored between the opposing upper and lower roller conveyors 5,
6 and a pallet inverter 10.
On the entry side of the lower roller conveyor 5, there is a storage conveyor 11 with a stopper perpendicular to the tire conveyance direction, and a lateral conveyor (not shown) for transferring the stacked tires M from the storage conveyor 11 onto the lower roller conveyor 5. A device is provided. Furthermore, a roller conveyor 12 for moving pallets is provided on one side of the rear end of the lower roller conveyor 5 in the tire conveyance direction.

The shelf pallet 4 has parallel longitudinal members 2 made of pipes mounted on a base 1 formed on a frame that can be transported by a forklift so as to form three stacked rectangular tire storage spaces opened on one side. and upper horizontal members 3, and the inner spacing of the parallel longitudinal members 2 is formed to be approximately the same as the height of the stacked tires M.

The pallet reversing machine 10 includes a pair of tilting arms 7 and 8 that are connected in an L shape and are rotatable in a vertical plane about a bent portion 9 by a tilting device 11. and is disposed on the front side of the lower roller conveyor 5 in the tire conveyance direction. One of the tilting arms 7 is capable of supporting the parallel vertical members 2 of the shelf pallet 4 in a sideways state between the rollers of the lower roller conveyor 5, and holds the parallel vertical members retracted from the tire conveyance surface. It is preferably formed into a comb-teeth shape, and is placed between the rollers of the lower roller conveyor 5 during shelving work in which stacked tires M are interposed from one side between the parallel vertical members 2 of the shelf pallet 4. The other tilting arm 8 has a comb-teeth shape that can be inserted between the rollers of the roller conveyor 12 and retracted from the tire conveying surface, and rotates 90 degrees after shelving work to stack pallets on the shelf. 4 is placed between the rollers of the roller conveyor 12.

The upper and lower roller conveyors 5 and 6 are arranged in three rows, facing each other, and can be driven by drive devices 14 and 15 via chain sprocket mechanisms 16 and 17.

A frame 18 and a chain sprocket mechanism 16 on the front side in the pallet conveying direction of the lower roller conveyor 5 move the parallel vertical members 2 of the shelf pallet 4, which are supported sideways on the tilting arm 7 of the pallet reversing machine 10, between the rollers. The frame 19 and the chain sprocket mechanism 17 on the front side of the upper roller conveyor 6 in the tire conveying direction are arranged parallel and vertically in the shelf pallet 4 supported horizontally on the tilting arm 7 of the pallet reversing machine 10. The upper roller conveyor 6 is formed so that the rollers can be moved in and out through the space between the pallet sheets 2 and 2, so that when the upper roller conveyor 6 projects the rollers into the shelf pallet 4 that is supported horizontally on the tilting arm 7 of the pallet reversing machine 10, Stacked tires M cooperate with the lower roller conveyor 5.
It is possible to sandwich and compress the sheets in the stacking direction and transport them into the shelf pallet 4.

An elevating frame 20 is disposed above the rear side of the lower roller conveyor 5 in the tire conveyance direction so as to be movable up and down by an elevating device 22 via an elevating guide 21 . Frame 1 of upper roller conveyor 6
9 is engaged with and supported by this elevating frame 20, and is configured to be able to retreat rearward in the tire transport direction to a position where it does not interfere with the tilting arm 7 rotated by the drive device 24 via the rack and pinion mechanism 23. There is.

(Function) The upper roller conveyor 6 is raised to the upper limit position by the lifting device 22 via the lifting frame 20. In this state, storage conveyor 1
Among the six stacked tires M placed on the lower roller conveyor 5, the three stacked tires M placed at fixed positions corresponding to each lower roller conveyor 5 by the stopper 25 are transferred to the lower roller conveyor 5 by a traversing device. Transferred above,
Next, the remaining three stacked tires M are transported and placed in a fixed position by the stopper 25, and then the above-mentioned transfer operation is repeated, and the lower roller conveyor 5 is driven so that they are placed on the lower roller conveyor 5. The stacked tires M are arranged in three rows of two each.

Next, the upper roller conveyor 6 is lowered, and the stacked tires M are sandwiched between the upper and lower roller conveyors 5 and 6, and in a compressed state in the stacking direction, the upper and lower roller conveyors 5 and 6 are driven to move the stacked tires M to the front side in the tire transport direction. When conveying, since the tire conveying surfaces of the upper and lower roller conveyors 5 and 6 are located inside the upper and lower parallel vertical members 2 of the shelf pallet 4 supported by the pallet reversing machine 10 in the opposing direction, the stacked tires M
are inserted between the parallel vertical members 2 of the shelf pallet 4 by upper and lower roller conveyors 5 and 6.

Thereafter, when the upper roller conveyor 6 is raised to the upper limit position, the compressive force of the stacked tires M is released, and the stacked tires M are interposed between the parallel vertical members 2 of the shelf pallet 4.

Next, the upper roller conveyor 6 is retreated to the rear side in the tire conveyance direction and removed from a position above the front side of the lower roller conveyor 5 in the tire conveyance direction, and then the pallet reversing machine 10 is rotated by 90 degrees, so that the shelf pallet 4 is It is erected on the pallet reversing machine 10 while being supported via the tilting arms 7 and 8, and is supported on the roller conveyor 12 via the base 1. It becomes possible to transport the stacked shelf pallet 4 to a predetermined position and then transport it to a multi-level warehouse using a forklift.

On the other hand, the empty shelf pallet 4 is transferred to the roller conveyor 12.
The pallet is taken into a predetermined position above the tilting arm 8 of the pallet inverting machine 10, and then tilted at 90 degrees by the pallet inverting machine 10, and supported in a sideways state on the tilting arm 7 of the pallet inverting machine 10. Further, the upper roller conveyor 6 is moved forward in the tire conveyance direction and returned to its original position. In this state, the above-mentioned shelf stacking operation is repeated.

Although the present invention is a tire racking device, it is of course applicable to a tire-like racking device such as a disk-shaped or donut-shaped device.

(Effects of the Invention) As described above, the present invention compresses the stacked tires in the stacking direction using the upper and lower roller conveyors, inserts them between the upper and lower parallel longitudinal members of the shelf pallet, and inserts them into the shelf pallet, Since this shelf pallet can be raised by rotating the pallet reversing machine 90 degrees when the upper roller conveyor is in the retracted state, stacked tires can be mechanically and reliably stacked on the shelf, and the shelves can be Sequence control is fully possible from the stacking procedure. Tire item (diameter and thickness)
Since it is only necessary to prepare a corresponding shelf pallet and adjust the amount of compression of the stacked tires by the upper roller conveyor, the present invention can be applied to stacked tires of various items. In addition, since the structure is simple and movement is easy, there are fewer failures.
With simple movements, the cycle time of shelf stacking work can be shortened and the efficiency of shelf stacking work can be greatly improved.
