Abstract

PURPOSE:To improve positioning accuracy and assure smooth operation in a stopping device for a truck travelling on rails by projecting stoppers beyond the rails to hold front-to-back the truck therebetween at a stopping position and supporting the truck by supporting members under the truck. CONSTITUTION:When a truck 10 reaches a predetermined position, a detector is operated to actuate a cylinder 111, so that a front stopper 114 is erected to come in abutment against a front bracket 10a of the truck 10 and thereby to stop the same. At the same time, a cylinder 111' is actuated to erect a rear stopper 114', which comes in abutment against a rear bracket 10b of the truck 10, so that the truck 10 is held front-to-back therebetween and fixed. Then, cylinders 115, 115' are moved up to support the brackets 10a, 10b of the truck 10 by lower stoppers 116, 116' under the truck 10 so as to prevent rattling due to diametrical difference between wheels 10c, 10d. Thus, positioning accuracy is improved and smooth loading operation is assured.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a stopping device that automatically stops a bogie running on a rail at a predetermined position.

<Prior art> As an example of the above-mentioned cart, a large number of shelves are stacked vertically, each column is rotatably supported on one side on a stand, and is biased by a spring or the like to tilt upward. There is a storage book trolley. This storage book cart is used to store temporary materials such as tire treads (A category). To store plate materials, the storage book cart is stopped at the loading position on the rail, and each column is rotated one by one from the bottom. This is done by lowering the tire to a horizontal position, and then sequentially loading multiple tire treads onto the rack using a chain conveyor or the like.

Conventionally, the storage book cart has been driven on rails by being pulled by a chain conveyor driven by a motor, and is stopped at the loading position by stopping the motor.

<Problems to be Solved by the Invention> However, since the above-mentioned conventional method of stopping the storage book cart merely stops the drive motor of the chain conveyor, the inertia of the motor and the storage book cart itself may cause problems. The problem arises that it is difficult to stop the storage book cart at the loading position accurately. In addition, if the rails are poorly laid or the axle is centered, the storage book stand IE will wobble and become unstable during loading, which will hinder smooth loading.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a truck stopping device that can accurately stop a truck at a predetermined position 1ξ, reliably position and hold the truck, and facilitate and accurately load +A materials onto the truck. be.

Means for Solving the Problems] In order to achieve the above object (1), the bogie stopping device δ of the present invention includes a rail, a bogie running on the rail, and a bogie that moves in and out of the rail to stop the storage bogie. It is characterized by comprising a stop F mechanism that clamps from the rear end of the mower and positions and stops it at a predetermined position, and a support mechanism that stops the positioned cart from below.

<When the action truck approaches a predetermined stopping position and starts to stop at a steady speed, the front stop mechanism protrudes and comes into contact with the front end of the truck to stop this truck, and the rear stop mechanism then protrudes one after another. The above-mentioned cart is clamped and accurately positioned and stopped at a predetermined position. Next, the supporting mechanism rises from below and stops against the lower part of the truck, supporting the truck without wobbling, and materials, etc. are loaded onto the truck. When the loading is finished, the carrier mechanism is lowered and the stop mechanism is retracted, the truck travels again and moves away from the stop position.

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

FIG. 1 is a plan view of a tire tread transfer device equipped with a truck stop device according to the present invention, where 9 is a loading chain conveyor which is the final part of this transfer device, and 30 is a chain conveyor 9 orthogonal to the loading chain conveyor 9. 10 is a storage book truck that runs on this rail 3o and stores the tire tread, 31.31' is a truck stopping device according to the present invention, and this device stops the storage book truck IO in a predetermined position. A stop mechanism 114 is positioned and stopped at the intersection position of the loading conveyor 9 and the rail 30, that is, the loading position A.
114' (see Fig. 3) and a supporting mechanism 116, which holds the storage book trolley lO positioned from below.
(See Figure 3).

In addition, 1 is an artificial roller conveyor that receives tire treads cut into a fixed length that are carried in at a constant speed and at regular time intervals on the carry-in conveyor line C, and 2 is a roller conveyor that changes the transport direction of the tire treads at right angles. 1-branch chain conveyor; 3 is an auxiliary alignment chain conveyor for aligning the tire treads; 4 is an auxiliary alignment chain conveyor for aligning a predetermined number (11) of tire treads as one set in conjunction with the auxiliary alignment chain conveyor 3; (Aligning and second branch chain conveyor that changes the multi-feed direction at right angles, 5 is a tire whose direction has been changed) - Roller conveyor that can transport red toward the third branch conveyor and keep it there for a certain period of time; 6 is this roller conveyor 5 Directly change the direction of transport of the tire trend above.
The third branch chain conveyor 7.8, which is changed to f1, is connected to the 1111 side of this first branch chain conveyor G, and is stopped for a certain time while transferring the tire tread to the loading chain conveyor 9. Get the stock on the chain conveyor.

The branch chain conveyor 1, the roller conveyor 5, and the third branch chain conveyor 6 are installed in series on the upper surface of a pedestal 11 at the same height. The loading chain conveyor 9 is a moving frame that is driven forward and backward toward the storage book cart 10 on a fixed frame 14 fixed to a base 13 that is driven up and down by a table lifter 12 with a pantograph structure provided at the bottom of the pit B. It is attached to 15. A loading chain conveyor 9 is mounted on the base 13.
A gate-shaped base frame 16 is constructed so as to straddle the pit B.
A guide post 17.17 is installed vertically on the bottom base B°, so that as the base I3 moves up and down, the base frame 16 is guided through four guide rollers 1B provided on both sides of the base frame 16. I have to.

A sprocket 19 is pivotally supported at the four corners of the upper protrusion +6a on one side of the base frame, a chain 20 is stretched over the sprocket 19, and a shelf unloading device 21 is fixed to the chain 20 toward the storage book cart 10 side, Chain protrusion 20 on the opposite side
The rod end of the drive cylinder 23 attached to the base frame 16 is fixed to a, and the shelf unloading device 21 is raised and lowered. The above-mentioned chain conveyor 7.8 is housed in a common frame 24 with both ends of its sprocket shaft pivotably supported, and this frame 24 has one end pivoted on the pedestal 11 (P
) Then, the wheel 25 attached to the lower part of the other end is placed on the frame support stand 16b''2 protruding from the base frame 16, and as the base frame 16 is raised and lowered, it moves around the fulcrum P as shown by the two-dot chain line. It rotates like this. Rotation f6 is, for example, ±lθ with respect to the horizontal line.

It is. The storage book cart 10 has a main wheel 26 at the center of the lower part and auxiliary wheels 27, 27 on both sides, and is driven by a chain conveyor 29, 29 installed on a pedestal 28 in the bit B, and laid in the center of the pedestal. It travels on the rail 30 and is moved to the loading position A by the stop device 31.31' (see Fig. 1).
It is designed to be positioned. On the other hand, on the upper part of the storage book cart IO, there are a large number of shelves 32, 32. ...are provided overlapping each other.
