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 which are piled up in a collection area.

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 disposed in the width direction of the cart, and a conveyor 6 is provided at the bottom for moving the plate-like object in the width direction of the cart.

The fixed guide rail 5 is provided with a hanging member 9 that is run by a guide roller 8, and one end of a movable guide rail 7 having approximately the same length as the fixed guide rail 5 is fixed to the lower end of the hanging member 9. The moving guide rail 7
is suspended in an outward direction of the trolley 1 so as to be movable in and out.

Reference numeral 10 denotes a movable frame, and the movable frame 10 has a guide roller 12 pivotally supported through a bracket 11 at the upper end of the movable frame 10, and the guide roller 12 is engaged with the movable guide rail 7 in the direction of the entire length of the movable guide rail. movably suspended.

A fluid pressure cylinder 13 is held in a vertical position at both ends of the movable frame 10 via a support member 14, and a support bar 16 is suspended between the tips of a piston rod 15 projecting downward. vacuum bat 1
7 will be equipped.

Therefore, the movable guide rail 7 is movable along the fixed guide rail 5, and the movable frame 10 is movable along the movable guide rail 7.
The vacuum pad 17 is configured to be moved up and down by the hydraulic cylinder 13.

Further, as shown in FIGS. 3 and 4, a forward/reverse motor 18 with a brake is mounted on the upper part of the fixed guide rail 5.
A sprocket 19 is fixedly attached to the output shaft of the motor 18, and sprockets 20a and 20b are supported at both ends of the fixed guide rail 5, respectively, and a chino 21 revolves around these sprockets 19, 20a and 2pb. Both ends of the chino 21 are fixed to the hanging member 9.

Furthermore, supporting members 7a, 7 are attached to both ends of the moving guide rail 7.
A total of four sprockets) 22a to 22b are pivotally supported on the top and bottom of b, and sprockets) 23a and 23b are pivotally supported on each bracket 11 of the movable frame 10, respectively.
A chain 24 is wound around the sprockets 22a to 22d on the moving guide rail side, one end of this chain 24 is wound around one sprocket 23a on the movable frame 10 side, and the other end is wound around the other sprocket 23b of the movable frame 10. After being hung and inverted, they are fixed to supporting members 7 a and 7 b, respectively.

As shown in FIG. 5, this chino 24 passes through a stopper member 25 which is vertically disposed on the movable guide rail protruding direction side from the middle part of the fixed guide rail 5, and this penetrating portion is constituted by a rod 26. Hold the stopper member 25 between the flange 27a, 27.
b is fixed, and the stopper member 25 and each collar 27a t
Buffer springs 28a and 28b are interposed between them and 27b, respectively.

With this structure, when the motor 18 is started in normal rotation from a state where the movable guide rail 7 and the movable frame 10 are completely housed within the width space of the trolley 1 as shown in FIG. 21 is driven, the movable guide rail 7 starts moving along the fixed guide rail 5 and starts protruding outward from the trolley 1.

Cheno 2 is wrapped around this moving guide rail I.
4 is fixed to the fixed guide rail 5 at the stopper member 25 by buffer springs 28b and 28b interposed between the stopper member 25 and the flanges 27a and 27b. At the same time as the movement, the chino 24 moves to the sprocket 2 of this moving guide rail 7.
2a to 22d will be relatively moved, and the movable frame 1
0 begins to move along the moving guide rail 7 in response to the running force of the chino 24.

That is, as the movable guide rail 7 is projected outward from the trolley 1 by the chino 21, the movable frame 10 is moved by the sum of the moving force of the movable guide rail T and the traction force by the chino 24.

Furthermore, as the moving guide rail 7 begins to move, the Cheno 24
When a driving force acts on the movable frame 10, immediately after this driving force acts, the load on the movable frame 10 side pulls the chain 24, and the collar 28b moves closer to the stopper member 25 side, causing the buffer spring to close. Since the spring 28b is compressed, the starting shock at the start of movement of the movable frame is absorbed by the buffer spring 28b.

Furthermore, as mentioned above, the movable frame 10 moves by the sum of the moving force of the movable guide rail 7 and the pulling force of the chino 24,
Of these, the moving speed due to the traction force of the chino 24 is 1/2 of the moving speed of the movable guide rail 7, since the chino 24 is wound around the sprocket 23a of the movable frame 10, reversed, and then fixed to the movable guide rail 7. Therefore, the movable frame 10 moves at a speed 1.5 times that of the moving guide rail 7.

As shown in FIG.
7 reaches directly above the plate-like object A, the motor 18 is braked and stopped, and then the hydraulic cylinder 13 lowers the support bar 16 to attract the vacuum pad 17 to the uppermost plate-like object 29. .

Next, when the fluid pressure cylinder 13 raises the support bar 16 and lifts up the plate-shaped object 29 that has been attracted by the vacuum pad 17, the motor 18 is reversed, and the movable guide rail 7 and movable frame 10 return to the original storage position 1. Begin to.

At this time, for the same reason as above, the moving guide rail 7
is moved back by the chino 21, whereas the movable frame 10 is moved back by the sum of the moving force of the moving guide rail 7 and the traction force by the chino 24.

Also, the starting impact of the movable frame 10 during the return movement with the buffer spring 2
Absorbed by 8a.

When the moving guide rail T and the movable frame 10 are pulled into the trolley 1 as shown in FIG. Transfer the object 29 to the conveyor 6,
This plate-like object 29 is sent out by the conveyor 6.

The transfer device of the present invention as described above can be used in the following ways.

That is, as shown in FIG. 6, a plurality of plate-like material accumulation areas A0 to A3 are placed on one side of the traveling rail 3 of the trolley 1, and a work machine B□ is placed on the other side.
~ With the transport conveyor C to B3 and other lines arranged, the trolley 1 is run to take out a plate-shaped object from an arbitrary collection area, and after transporting it by the desired work machine or transport conveyor 1. It can be used like sending it in.

In the present invention, a fixed guide rail is provided at the upper part of the transfer device main body, and a conveyor means is provided directly below the fixed guide rail. Since the movable frame movably suspended from the guide rail is equipped with a plate-shaped object gripping means via an elevating means, the first element is driven by a motor to move the movable guide rail to the fixed guide rail. At the same time as the movable frame is projected in the extension direction, the movable frame is moved in the projecting direction along the moving guide rail, and the plate-shaped object gripping means is moved onto the plate-shaped object accumulation area on the outside of the transfer device main body, and the movable frame is moved by the means. Although it is capable of gripping a plate-shaped object, the moving guide rail and movable frame can be housed within the main body of the transfer device by pulling the moving guide rail and movable frame into the main body of the transfer device.

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

In addition, in the present invention, the second element is wound around and wrapped between the groove wheels at both ends of the movable guide rail, and both ends of this cable are wound around the respective groove wheels pivotally supported on the movable frame, so that the direction can be determined. Since it is fixed to the end of the movable guide rail after turning, when the movable guide rail is moved along the fixed guide rail by the first element, not only this movable guide rail but also the movable frame is attached to the movable guide rail. Therefore, there is an advantage that the movable guide rail and movable frame can be moved at different speeds by a single motor, and the movable frame has a moving speed 1.5 times that of the movable guide rail. 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.

Furthermore, in relation to the structure of the element, for example, a method such as a jib extension/retraction device in a jib crane having a plurality of moving jibs, in which one element is passed around each moving jib and rotated. For this reason, if the element is a chain, the cost of the element becomes very high and the weight of the element increases considerably, which increases the cost of the entire device. Although there are inconveniences such as the cost burden and weight burden that the elemental body occupies is excessive, and the elongation that occurs in the elemental body becomes large, as in the present invention, the elemental body is If the movable guide rail and movable frame can be moved in and out of the fixed guide rail by being divided into two element bodies and rotated independently, the first element body and the second element body The total length of the element body including the body is much shorter than the rotating system of the element body in the above-mentioned jib extension and retraction device, and the length of the element body is divided into the first and second element bodies. Since the length is shorter, the elongation that occurs in each element is much smaller than the elongation that occurs in a single element in the jib extension device, and therefore the movable frame and movable frame can perform accurate expansion and contraction movements. This allows the plate material to be reliably transferred to a predetermined position.

Moreover, the second blank is inserted through a stopper member protruding from the fixed guide rail, and the flange is fixed to the blank by sandwiching this stopper member, 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, and the plate-like objects can be transported stably and without danger.

Furthermore, since the main body of the transfer device is movable in the longitudinal and widthwise direction of the main body, that is, in the direction orthogonal to the direction in which the plate-like objects are transferred, the plate-like objects can be simply taken out from a certain accumulation area and moved laterally from the trench. Not only can it be transported and sent to a fixed location, but the plate-like object taken out from a fixed plate-shaped volume field can be moved to any desired location by holding the main body of the transfer device and then moving the main body of the device in the vertical direction. It is possible to send plate-shaped bodies, and the accumulation site for plate-shaped bodies is not limited to a fixed location as mentioned above, but can be provided at any position along the running rail of the transfer device main body, so that one The transfer device allows the transfer of plates over a wide range.

Furthermore, in the present invention, the plate-shaped object gripping means is installed on the movable frame via a vertical hydraulic cylinder, so that it can move up and down freely, so that the plate to be transferred is not at a fixed level position. It can also be lowered and grasped at the level position where the board is placed.
