Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for grasping, taking out and transporting plate-shaped objects such as iron plates and glass plates one by one that are piled up in a collection site.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In Figs. A fixed guide rail 5 is provided which is arranged in the width direction of the trolley, and a hanging member 7 that runs by a guide roller 6 is provided on this fixed guide rail 5.
An intermediate portion of a movable guide rail 8 having approximately the same length as the fixed guide rail 5 is fixed to the lower end of the hanging member 7, so that the movable guide rail 8 can selectively move in and out of both outward directions of the trolley 1. It is suspended.

Reference numeral 9 denotes a movable frame, and the movable frame 9 has a guide roller 11 pivotally supported at its upper ends through brackets 10, and the guide roller 11 is engaged with the movable guide rail 8 and moved in the entire length direction of the movable guide rail. possible to be suspended.

A fluid pressure cylinder 12 is held in a rigid position at both ends of the movable frame 9 via a support member 13, and a support bar 15 is suspended between the tips of a piston rod 14 projecting downward. Vacuum pad 16
will be equipped.

Therefore, the movable guide rail 8 is movable along the fixed guide rail 5, and the vacuum pad 16 is configured to be raised and lowered by the hydraulic cylinder 12.

Further, as shown in FIGS. 4 and 5, a forward/reverse motor 17 with a brake is mounted on the upper part of the fixed guide rail 5.
A sprocket 18 is fixedly attached to the output shaft of this motor 17, and sprockets 19a and 19b are pivotally supported at both ends of a fixed guide rail 50, respectively.
A chain 20 is wound around B, 19a, and 19b, and both ends of the chain 200 are fixed to the hanging member 7.

Furthermore, supporting members 8a, 8 are attached to both ends of the moving guide rail 80.
A total of four sprockets 21a to 21d are pivotally supported on the upper and lower sides of b, and sprockets 22a and 22b are each pivotally supported on each bracket 10 of the movable frame 9, and sprockets 21a to 21d on the movable guide rail side. The chain 23 is wound around, one end of the chain 23 is wound around one sprocket } 22 d on the movable frame 9 side, and the other end is wound around the other sprocket } 22 b of the movable frame 9 , and after being reversed, each of them is attached to a support member. It is fixed to 8a and 8b.

As shown in FIG. 6, this chain 23 passes through a stopper member 24 hanging vertically from the fixed guide rail 5, and this penetrating portion is made up of a rod 25, with the stopper member 24 sandwiched between the rod 25. Tsuba 2 at the required interval
6a and 26b are fixed, and the stopper member 2
A buffer spring 2 is provided between each collar 26a and 26b.
7a and 27b are fitted with an intervening mantle.

With this structure, when the motor 17 is started to rotate in the normal direction from a state where the movable guide rail 8 and the movable frame 9 are completely housed within the width space of the trolley 1 as shown in FIG. 20 is driven, the movable guide rail 7 starts moving leftward in the drawing along the fixed guide rail 5 and starts protruding outward from the cart 1.

Chain 23 wound around this moving guide rail 8
is fixed to the fixed guide rail 5 at the stopper member 240 portion by buffer springs 27a and 27b interposed between the stopper member 24 and the flanges 26a and 26b, so that the movable guide rail 8 moves simultaneously. The chain 23 is the sprocket of this moving guide rail 8}2
1a to 21d will be relatively moved, and the movable frame 9
receives the running force of this chain 23 and moves the moving guide rail 8.
Start moving along.

That is, as the movable guide rail 8 is projected outward from the carriage 1 by the chain 23, the movable frame 9 is moved by the sum of the moving force of the movable guide rail 8 and the traction force by the chain 23.

Incidentally, as the moving guide rail 8 starts moving, the chain 23
When a driving force is applied to the movable frame 9 by , immediately after this driving force is applied, the chain 2 is reversely
3 is pulled, the collar 26b moves closer to the stopper member 24 and the buffer spring 27b is compressed, so that the starting impact after the movable frame starts moving is absorbed by the buffer spring 27b.

In addition, the movable frame 9 is connected to the moving force of the moving guide rail 8 and the chain 2.
As mentioned above, the movement speed of the chain 23 due to the traction force, that is, the movement speed of the movable frame 9 with respect to the moving guide rail 8, is such that the chain 23 is moved by the sum of the traction forces of the chain 23 and the sprockets of the movable frame 9. After wrapping around 22b and inverting it, it is fixed to the moving guide rail 8, so the moving speed is V2 of the moving guide rail 8, and the movable frame 9 moves at a speed 1.5 times the moving guide rail 80.

As shown in FIG.
When the motor 17 reaches directly above the plate-like object A, a brake is applied to the motor 17 to stop the motor 17, and then the hydraulic cylinder 12 lowers the support bar 15 to attract the vacuum pad 16 to the uppermost plate-like object 28.

Next, when the fluid pressure cylinder 12 raises the support bar 15 and lifts up the plate-shaped object 28 that has been attracted by the vacuum pad 16, the motor 17 is reversed, and the movable guide rail 8 and movable frame 9 move back to the original storage position. start.

At this time as well, for the same reason as above, the moving guide rail 8
is moved back by the chain 20, whereas the movable frame 9 is moved back by the sum of the moving force of the moving guide rail 8 and the traction force by the chain 23.

Also, the starting impact of the movable frame 9 during this return movement is applied to the buffer spring 27.
absorbed by a.

When the motor 17 is further driven in the reverse direction from the state where the movable guide rail 8 and the movable frame 9 are pulled into the trolley 1 as shown in FIG. Then, the movable frame 9 also moves in the same direction along the movable guide rail 8, so that the movable guide rail 8 and the movable frame 9 protrude outward from the truck 1 as shown in FIG.

When the movable frame 9 reaches directly above the working machine (or conveyor) B due to this protrusion, the motor 17 is stopped, and the fluid pressure cylinder 12 lowers the support bar 15 to remove the plate-like object 28 that is being sucked by the vacuum pad 16. Transfer to work machine B.

Thereafter, the movable guide rail 8 and the movable frame 9 move backward as the motor 17 is driven to rotate normally, and are housed in the carriage 1 as shown in FIG.

The present invention is as described above, and a moving guide rail is movably suspended from a fixed guide rail provided on the upper part of a moving device main body, and a movable frame movably suspended from this moving guide rail is raised and lowered. Since the device is equipped with a plate-like object gripping means, the movable frame can be moved along the moving guide rail at the same time as the driving guide rail is projected in any direction outside the transfer device main body. direction, move the plate-like object gripping means onto the plate-like object accumulation area on the outside of the transfer device main body, and grip the plate-like object by the means, and then move the moving guide rail and the movable frame in the reverse direction. The moving guide rail and movable frame pass through the transfer device main body and protrude to the outside of the transfer device main body in the opposite direction, allowing the gripped plate-shaped object to be sent to the work machine, and even when not in use. By pulling the movable guide rail and movable frame into the transfer device main body, the movable guide rail and movable frame can be housed within the transfer device main body.

Therefore, the width of the transfer device main body can be kept within the entire length of the fixed guide rail, and the width of the transfer device main body can be made compact.

In other words, in the conventional transfer device, the guide rail was provided over the entire length of the movement range of the plate-shaped object gripping means and was movably suspended from the guide rail, without providing an expansion/contraction mechanism for the fixed guide rail and the movable guide rail. The overall length of the guide rail, that is, the width of the main body of the transfer device has become large, resulting in inferior functionality.

Furthermore, in the present invention, the movable guide rail and the movable frame can be made to protrude to either side of both outer sides of the main body of the transfer device, so that the plate-like objects can be freely transferred from right to left and from left to right. , it is possible to improve work efficiency.

Further, in the present invention, a second elemental body is wound around and wound between the guiding wheels at both ends of the moving guide rail, and both ends of this elemental body are wound around each guiding wheel pivotally supported on a movable frame, so that the direction , and then fixed to the end of the moving guide rail, so when the moving guide rail is moved along the fixed guide rail by the first element, not only this moving guide rail but also the movable frame is attached to the moving guide rail. Therefore, there is an advantage that the movable guide rail and the movable frame can be moved all at once by a single motor at different speeds, and the movable frame has a moving speed 1.5 times that of the movable guide rail. Therefore, the moving speed of the moving guide rail can be suppressed to a relatively low speed, and the motor can be easily controlled and used stably.

In addition, the second cable member is inserted through a stopper member protruding from the fixed guide rail, and the flange is fixed to the element body with this stopper member in between, so that a buffer is created between the stopper member and each flange. Since the springs are interposed, the shock of starting the movable frame is absorbed by the buffer springs, so that the plate-like objects can be transported stably and without danger.
