Description

[Detailed Description of the Invention] This invention relates to an apparatus for sequentially stacking tires placed in a horizontal state.

Recently, after wheels are attached to Yuchiya, they are transported to an automobile assembly plant, and in this case, the tires with wheels attached are transported to a predetermined position by a conveyor, and then these tires are moved to a predetermined location. They are piled up one by one and loaded onto a transport vehicle.

In addition, it is desired that this type of stacking device not only be able to stack tires accurately, but also that the configuration be as simple as possible and that it can be used with less failure.
No device has been found that can fully satisfy these demands.

This idea was made to improve the above situation.
The purpose is to be able to easily and efficiently stack tires that are placed horizontally, to be able to stack them up reliably, and to be able to build them up relatively simply and easily and inexpensively. It is an object of the present invention to provide a tire stacking device as described above.

This invention will be explained below with reference to embodiments shown in the drawings.

In the figure, reference numeral 1 denotes a roller conveyor, and this conveyor 1 sequentially conveys tires a to which wheels are attached in the direction of arrow A.

A gate-shaped pedestal 2 is provided at the end of the conveyor 1 so as to straddle this conveyor 1, and this pedestal 2
0. Attach the guide frame 3 along the vertical direction at the center of both sides.

Guide rollers 5, which are pivotally supported on the sides of both support members 40 disposed on both sides of the conveyor 1, are rotatably connected to the guide frame 3 so as to be movable in the vertical direction, and are attached to the center of the upper part of the trunk support member 4. An air cylinder 80 and a rod 9 attached to the upper center of the pedestal 2 are fixed to the connector 6, and the cylinder 8 is actuated to move the trunk support member 4.
is configured to reciprocate vertically with a constant stroke.

Both song plates 10 are fixed to the inner side of the lower end of the trunk support member 4, and pins 11 are protruded from both song plates 10.
The horizontal elongated holes 13 of both support claws 12 are engaged with the elongated holes 13.
The supporting claws 12 move in the front-rear direction as they move relative to the bin 11, and the bin 11 moves in the elongated hole 1.
3 (the state shown in FIG. 2), the front side of the support claw 12 tends to swing downward; stopper 14
When the pin 11 moves toward the front side of the elongated hole 13, the center of gravity of the claw 12 moves toward the rear side.

A cam 15 is fixed to the lower end of the guide frame 3, and a claw 1 is attached to an inclined surface 16 formed inside the cam 15.
When the rear end surfaces of 2 come into sliding contact, this claw 12 is pushed forward and returns to its original position.

In addition, 17 and 18 in the figure are both stoppers that protrude and sink from the upper surface of the conveyor 1 to stop the tires a.

The operation of the tire stacking device configured as described above will be explained.

After the stopper 11 at the end portion is made to protrude from the upper surface of the conveyor 1, the tires a to which the wheels are attached are sequentially conveyed by the conveyor 1 in the direction of arrow A.

When the first tire a' comes into contact with the stopper 1T, the cylinder 8 is actuated to raise both support members 4 in the direction of arrow B.

Then, as shown in FIG. 3, the supporting claws 12, which project inwardly from the support member 4 and are supported in a horizontal state, rise in the direction of arrow B and are placed on the conveyor 1 in a horizontal state. Support the lower surface of the first tire a' and lift it up.

When the first tire a' is lifted, as shown in Figure 4,
The next tire a' is conveyed on the conveyor 1, comes into contact with the stopper 11, and is positioned directly below the lifted first tire a'.

In this state, when both support members 4 are lowered in the direction of arrow C by cylinder 8, the first tire a' supported by both support claws 12 is also lowered and placed on the next tire a.

Further, when both support members 4 are lowered, as shown in FIG. 11 as a fulcrum and rotates in the direction of the arrow.

When both claws 12 are rotated by a predetermined angle or more, the long holes 13 of both claws 12 slide downward while being guided by the bottle 11, and both claws 12 move in the direction of arrow E. Therefore, both claws 12 Since it descends while moving backwards, these claws 12 will not get caught on the next tire a'', and even if the vertical stroke is relatively small, both claws 12 will be able to catch the next tire a'' below. reach.

When the claws 12 reach below the tire l, the rear ends of the claws 12 come into sliding contact with the inclined surface 16 of the cam 15, as shown in FIG. pushed forward.

Then, the bottle 11 reaches the rear end of the elongated hole 13 of both claws 12, and the front side of both claws 12 with the bottle 11 as a fulcrum becomes heavy, so the front side of both claws 12 rotates in the direction of arrow G. , the rear upper surfaces of both claws 12 abut against the stopper 14, and both claws 12
protrudes forward and returns to the horizontal state (the state shown in Figure 3).

In this state, when both claws 12 are raised in the same manner as above, the two tires al and all are lifted, and then the third tire a is conveyed by the conveyor 1, and the two lifted tires l and l are transported. ' , the two tires a/y reached just below a/y, and then both claws 12 were lowered and lifted up.

A'' is placed on the third tire a, and this operation is repeated until a predetermined number of tires a are stacked at the end of the conveyor 1.

As explained in detail above, in this invention, when both support claws reach the bottom of the tire, the two support claw cams push each other forward and return to their original positions, so that the lower surface of the tire's largest peak is reliably supported. In addition, when the above-mentioned support claws move downward, the center of gravity of both support claws moves rearward, so it moves downward smoothly without getting caught on the tire. In addition to being able to reliably and quickly stack tires that are placed horizontally, the movement of the gravity of the support claws is restored by a cam, and no power is used, so there are fewer failures, and the support By moving the claws back and forth, the vertical stroke can be reduced, making tire stacking very efficient.

In addition, the support claw itself moves back and forth and returns to its original position using a cam, and the support member only reciprocates in the up and down direction, reducing its stroke.
The structure is relatively simple and can be manufactured easily and inexpensively, and the entire device can be made compact.
