Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is based on an engaging movement action of at least two hooks provided on one side of a bogie and at least two hook receivers pivotally attached so that an unbalanced load is not applied to the chain. The present invention relates to a trolley moving device that can accurately move a trolley toward one side by keeping the distance between the trolley and the chain always constant by simply rotating the chain unidirectionally without using a rail.

[0002]

2. Description of the Related Art Conventionally, it is well known that a chain conveyor type moving device has been used to move a carriage to a position for storing goods or to move a carriage containing goods to one side. Has been.

In the chain conveyor type moving device, a pair of rails for accurately moving and moving the carriage toward one side and a chain conveyor are arranged side by side, and a plurality of hook receivers mounted on the chain conveyor are provided. One of them is engaged with a hook provided on the dolly side, and the dolly is moved toward one side along the rail by the rotation operation of the chain conveyor.

[0004]

By the way, when the trolley is moved to one side by the above-mentioned chain conveyor type moving device, an unbalanced load due to the weight load of the trolley being directly applied to the chain conveyor itself. for,
The chain conveyor will be distorted, resulting in disengagement of the hook receiver and hook, or the chain conveyor will extend more than necessary and slip off from the sprocket, ensuring accurate long-term movement of the bogie. Perhaps it could not be achieved, but there was a problem that the equipment cost was high due to the use of rails.

The present invention relates to at least two hooks provided on one side of the bogie and at least two hook receivers pivotally attached so that an unbalanced load due to the weight load of the bogie is not directly applied to the chain. It is an object of the present invention to provide a moving device for a bogie that can be accurately moved toward one side while keeping a constant distance between the bogie and the chain by mere one-way rotation of the chain by joint movement, without using a rail. I am trying.

[0006]

In order to achieve the above object, in a moving device for a dolly according to the present invention, a dolly having at least two hooks mounted on one side at intervals, and the dolly on one side. The moving conveyor casings to be moved are arranged side by side, and the chain that is suspended and housed in the moving conveyor casing has a hook receiver that symmetrically has a pair of guide rollers that roll along the left and right inner walls of the moving conveyor casing. The two hooks are pivotally attached to each other at the same intervals so as to be rotatable, and each hook receiving part extending from the moving conveyor housing to the trolley side has an engaging portion engaging with the hook. It is provided.

[0007]

At the time of starting the movement of the carriage, first, the carriage is moved to one side of the moving conveyor housing at a distance such that at least two hooks and at least two hook receivers can be engaged with each other by manual operation. Let me set it.

[0008] Then, if the chain accommodated in the movable conveyer housing in a suspended manner is rotated in the direction of the arrow, the at least two hook holders and the at least two hooks that rotate rotate with each other through the engaging portion. Engaged to orient the carriage in the direction parallel to the moving conveyor housing and allow it to move accurately without rails.

By the way, when the carriage is moved as described above, a pair of guides that roll along the left and right inner walls of the moving conveyor housing are attached to the plurality of hook receivers pivotally attached to the chain so as to be rotatable left and right. Since the rollers are provided symmetrically, the weight load of the carriage generated when the carriage is moved by the engagement between the hook receiving member and the hook is not directly added to the chain, and all of them are transferred through the rolling rollers. Since the chain is leaned by the left and right side walls of the moving conveyor housing, the chain is distorted by an eccentric load, the hook and hook receiver are disengaged, and the chain is extended without causing an accident that the chain derails from the sprocket It is possible to move in parallel with the conveyor housing to one side at a fixed interval.

[0010]

An embodiment will be described with reference to the drawings.

In FIG. 1 to FIG. 6, reference numeral 1 denotes a horizontally long moving conveyor housing installed on a floor surface 2. In the moving conveyor housing 1, a driving sprocket 3 and a driven sprocket 4 are suspended. The endless belt-shaped chain 5 is housed so that it can be rotated by the motor M in the arrow direction.

A plurality of mounting seats 6 ... Are attached to the circumferential surface of the chain 5 at equal intervals, and the plurality of mounting seats 6 ... A pair of guide rollers 7, which roll along the left and right inner walls 1a, 1b.
8 is symmetrically mounted on the hook support 9 ...
It is pivotally attached so that it can freely rotate in the left-right direction about 0. In addition, the distance L1 between the axes of the pair of guide rollers 7 and 8
Is formed to be larger than the width L2 of the left and right inner walls 1a and 1b of the moving conveyor housing 1.

A window 1 opened on one side of the moving conveyor housing 1
Hook receivers 9 extending outward from 9
An engaging portion 11 with which a hook 13 to be described later is engaged is concavely provided on one side on the inner side of.

Reference numeral 12 is a trolley capable of accommodating a large number of articles conveyed in a direction orthogonal to the moving conveyor casing 1 through a suitable conveying means in a plurality of rows and in a plurality of stages. On the lower side of the one side, at least two hooks 13, 13 that engage with the engaging portions 11 of the above-mentioned at least two hook receivers 9, 9 are arranged at the same intervals as the hook receivers 9, 9. It is installed.

As shown in FIGS. 5 and 6, the hook 13 described above is formed in a vertical shape, and the upper side thereof is mounted on a mounting bracket 14 mounted on one side lower side of the bogie 12 and is pivotally mounted on the mounting bracket 14. In addition, the vertical surface 16 provided on one front side of the hook 13 is formed so as to be received by the stopper wall 17 projecting on the surface side of the mounting bracket 14, so that the hook 13 can support the shaft portion 15 as a shaft. Is configured so that it can be rotated only in the counterclockwise direction, and when the handle 13 of the carriage 12 is held and moved parallel to one side of the moving conveyor housing 1 at a predetermined interval, the hook 13 is set. When the carriage 12 is moved, it can be pivoted counterclockwise so that the carriage 12 can be easily set, and when the carriage 12 is moved, the vertical surface 16 of the hook 13 is a stopper wall 17. Received and moved in rotation It is configured to be moved toward the one of the carriage 12 by being pressed by the moving direction by the hook receiving fixture 9 that.

[0016]

Since the present invention is configured as described above, it has the following effects.

According to the first aspect of the present invention, at least two hooks are mounted on the carriage side of the carriage and the moving conveyor housing at the same interval, and at least two hooks pivotally mounted on the chain side. Since it is securely connected by engaging with the hook receiver, the relative position between the carriage and the moving conveyor housing can be accurately determined without the rail, and while the mere one-way rotation operation of the chain causes the carriage to move in parallel with the moving conveyor housing, Can be moved accurately toward.

In addition, since the hook receiver pivotally attached to the chain so as to be rotatable left and right is provided with a pair of guide rollers symmetrically rolling along the left and right inner walls of the moving conveyor housing, the carriage that is generated during movement is generated. The left and right inner walls receive the weight load of the chain through a pair of guide rollers to prevent an unbalanced load from being applied to the chain, which causes the chain to be distorted due to the unbalanced load, and the hooks and hook receivers to disengage from each other. It is possible to prevent the occurrence of an accident in which the movement of the vehicle is stopped or the vehicle is derailed from the sprocket due to the extension of the chain, and it is possible to efficiently achieve a smooth trolley movement operation for a long period of time with a simple and inexpensive device.
