Description

[Detailed description of the invention] (Field of industrial application) The present invention is a tire drop lifter device installed in a tire sub-line for automobile assembly, which turns tires conveyed horizontally by a conveyor into vertical shapes and carries them out from the lower end. It is related to.

(Prior art) A tire drop lifter device installed in a tire sub-line for automobile assembly has a tire transport guide member attached to the tire drop lifter that transports tires in a horizontal direction. The lower part of the curved part is vertical along the front vertical column of the frame, and serves as a vertical guide part that guides the tire vertically downward. It has arms.

The distance between the tire receiving frame member and the vertical guide section that guides the downward conveyance of the tire vertically remains unchanged. Therefore, in the case of a large-diameter and thick tire, a horizontal tire will be moved horizontally. The tire is transferred to the tire receiving arm from the bending section following the conveyance section, and as the lifter descends, it rises to a vertical position. However, in the case of small diameter tires, the tire does not rise and the position at the lower end of the lifter is inclined. This may cause problems during removal.

(Problems to be Solved by the Invention) To solve the problem of transferring a tire transported in a horizontal state to a tire drop lifter and ensuring operation to bring the tire into a vertical state while reaching the lowering end.

(Means for solving the problem) The present invention uses a tire lifting guidance mechanism provided on the tire receiving member to reduce the resistance during tire lifting and encourage the lifting, and also to change direction following the horizontal conveyance section. A tire raising member provided at a location corresponding to the lower part of the curved part is used to assist in raising the tire, and its base ends are fixed to both sides of the lower end of a tire receiving member that can be raised and lowered. A guide tube protruding from the tire conveyance guide member side is provided, a tire receiver tube is slidably inserted into the outer periphery of the guide tube, and a tensile force is applied to the tire receiver tube in the direction of the proximal end of the guide tube. The present invention provides a tire drop lifter device equipped with a biasing tire lifting guide mechanism.

(Function) The present invention is such that when the tire is transferred from the deflection bending section following the horizontal conveyance section to the tire receiver tube of the tire raising guide mechanism and received, the tire receiver tube elastically slides toward you by the lower end of the tire. The tire moves forward to reduce the resistance when the tire starts up and to encourage the tire to start up, and the tire reliably assumes a vertical posture along the vertical guide part and reaches the lowering end.

(Example) Embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a tire conveyance guide member 2 attached to a tire drop lifter 1 on a tire subline for automobile assembly consists of a horizontal conveyor section 3 disposed on the ceiling and a tire conveyor guide member 2 attached to a tire drop lifter 1 on a tire subline for automobile assembly. It consists of a vertically curved portion 4 and a vertical guide portion 7 that descends along a vertical column portion 6 of a frame 5 of the tire drop lifter 1.

The tire drop lifter 1 has a frame-shaped tire receiving member 9 that is movable up and down along guide rods 8, 8, and this tire receiving member 9 is connected to the tire transport guide member 2.
Tire raising guide mechanisms 10, 10 are provided at the lower end on the side facing the road and on both sides, and a tire raising guide mechanism 10 is provided at the lower end of the deflection curved portion 4 of the tire conveyance guide member 2. A member 11 is provided.

As shown in FIG. 3, the tire raising guide mechanism 10 includes a guide tube 12 whose base end is fixed to the lower end of the tire receiving member 9, protrudes toward the tire conveyance guide member 2, and whose left end is closed. This guide tube 1
A tire receiver tube 13 with its right end closed is slidably inserted into the outer periphery of the guide tube 12, and the other end of a tension spring 14 whose one end is fixed to the closed end 12a of the guide tube 12 is fixed to the closed end 13a of the tire receiver tube 13. , tension spring 14
The closed end 13 of the tire receiver 13 due to the tensile force of
a is brought into contact with the open end 12b of the guide tube 12.

Further, the tire raising guide mechanism 10 is formed such that the lower part of the forward end of the tire that transitions from the curved deflection section 4 at the rising end of the tire receiving member 9 is located on the tire receiving cylinder 13.

The tire raising member 11 has a direction changing curved portion 4
It is a horizontal roller with both ends pivotally supported at the tip of a branch 15 fixed at the lower end, and the position of this tire raising member 11 is the same as when the tire receiving member 9 is at the rising end. It is located slightly lower facing the right end of the tire receiving tube 13 of the guiding mechanism 10.

A left/right sorting mechanism 16 is provided at the lower end of the tire receiving member 9 in the tire drop lifter 1, and by tilting the platform 17 of this left/right sorting mechanism 16 to the left, the tire passes through the left ramp 18.
The tire is rolled to the left standby section 19 and held there by the tire stopper 20, and the platform 17 is tilted to the right to move to the right ramp 2.
1, the tire rolls to the right standby section 22, and is held stopped by a tire stop 23.

a horizontal conveyance section 3 of the tire conveyance guide member 2;
The direction changing curved section 4 and the vertical guide section 7 are provided with a large number of horizontal rollers that can freely rotate in a row on the conveyance path.

In the figure, 24 is a stopper that receives the tire at the head of the tire row being fed on the horizontal conveyance section 3, and 25 is a stopper that holds the next tire when the first tire is transferred to the tire drop lifter 1. It is a stop for doing.

Since the present invention is configured as described above, when the first tire in the row of tires sequentially fed on the horizontal conveyance section 3 is released from being held stopped by the stopper 24, the tire receiving member waits at the rising end in advance. 9, the lower part of the forward end of the tire is placed on the tire receiver tube 13, and as the tire receiver member 9 starts to descend synchronously, the lower part of the forward end of the tire moves the tire receiver tube 13 toward the direction indicated by the arrow. The tire receiver 13 resists the elasticity of the tension spring 14 in the direction a.
While sliding, the tire rises and becomes vertical, and as the tire receiving member 9 descends, the upper part of the tire hits the tire raising member 11, and as if kicked up, the tire rises and becomes vertical. When the tire receiving member 9 reaches the descending end with the tire receiving member 9, the tire gets on the platform 17, and depending on the inclination of the platform 17, it falls into the left waiting section 19 or the right waiting section 22 and is sorted. .

(Effects of the invention) The present invention provides a tire raising guide mechanism on the tire receiving member to minimize the resistance when the tire becomes vertical, and a tire raising member on the tire conveyance guide member. Since the tire is kicked up when it becomes vertical, the tire is promoted and assisted in raising the tire in this way, so that the tire can be reliably made vertical in the tire drop lifter.

Furthermore, the tire size range of the tire drop lifter can be expanded.
