Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a thin plate transfer device suitable for transferring a fixed length thin plate made of metal or synthetic resin in one direction in a length direction from an arbitrary table and transferring it to a conveyor device. It is a thing.

[0002]

[Prior art]

 As a device for taking out a thin plate made of metal or synthetic resin and having a long length in one direction from an arbitrary thin plate stand, sending it out in the length direction and transferring it to an arbitrary conveyor, from above the thin plate stand. A guide rail extending above the conveyor is installed, and an elevating table of approximately the same length as the thin plate is hung up and down on a horizontal slide table that can slide along the guide rail. Arrange the suction pads face down, move the horizontal slide table just above the thin plate placed on the thin plate stand to stop it, and then lower the elevating stand to move it down with multiple suction pads. It is known that a thin plate is adsorbed, then the elevating table is raised to move the horizontal slide table above the conveyor, and then the elevating table is lowered to release the thin plate from the suction pad.

[0003]

[Problems to be solved by the device]

 Since the above-mentioned conventional device lifts a fixed length thin plate over its entire length, there are two suction pads at the front and rear ends of the thin plate, or a total of three suction pads at the front and rear ends and the middle, depending on the length of the thin plate. I needed a lot of them. Further, at the supply side end of the conveyor, a mounting portion having the same length as the thin plate is required in order to mount the entire length of the thin plate.For example, the conveyor performs processing such as painting, polishing or drying on the thin plate. When passing through the processing chamber for carrying out, it is necessary to project the above-mentioned conveyor to the entrance side of the processing chamber by at least a length equal to the length of the thin plate, which causes a problem that the total length of the conveyor becomes long. In addition, the moving distance of the horizontal slide table also increases according to the length of the thin plate, which causes a problem that the device becomes large.

In this invention, the suction pad may be provided only for adsorbing the front end of the thin plate having a fixed length, and the length of the thin plate mounting portion and the moving distance of the horizontal slide table in the conveyor can be significantly reduced. This allows the installation area to be reduced.

[0005]

[Means for Solving the Problems]

 In this invention, a thin plate stand for placing the thin plate is placed in series on the supply side of a conveyor for carrying a fixed length long plate in one direction and conveying it in the length direction. Two elevating devices are installed side by side on a horizontal slide that moves between the supply side end part and the upper part of the thin plate stand, and the suction pad is attached to the elevating member that is raised and lowered by one elevating device, and the other elevating device is The thin plate transfer device is characterized in that a pressing roller is provided downward on an elevating member that moves up and down.

It is to be noted that a supply roller is provided in contact with the upper surface of the conveyor on the supply side, and the descending positions of the pressing roller and the suction pad on the conveyor are set between the end of the conveyor on the supply side and the supply roller. Is preferred.

[0007]

[Action]

 Position the horizontal slide table above the front part (conveyor side part) of the thin plate, and lower the suction pad by the operation of one of the elevating devices to adsorb the front end side of the thin plate, and then raise the suction pad. When the front part of the thin plate is lifted up, the rear part of the suction part of the thin plate bends and the rear end is supported by the thin plate base or the upper surface of the thin plate. Then, when the horizontal slide is advanced to the conveyor side, the thin plate is conveyed to the conveyor side with its rear end dragged. After the front edge of the thin plate reaches above the conveyor, the suction pad is released from the suction and the other lifting device is activated to lower the pressing roller.The pressing roller presses the front part of the thin plate against the upper surface of the conveyor. Then, the thin plate is conveyed by the conveyor. If more than half of the total length of the thin plate is placed on the conveyor, the thin plate will be conveyed without any problems even if the pressing roller is raised, so raise the pressing roller to move the horizontal slide base to the thin plate. Retreat to the table.

When a supply roller is provided on the supply side of the conveyor, if the front end of the thin plate being conveyed by the pressure contact of the pressing roller enters under the supply roller, even if the pressing roller does not have pressure contact. Transport becomes possible. Therefore, by setting the distance from the supply-side end of the conveyor to the supply roller to be less than 1/2 of the thin plate length, the pressing roller is raised before half of the total length of the thin plate is transferred onto the conveyor, and the horizontal slide is performed. The moving table can be retracted onto the thin plate table.

【Example】

 In FIGS. 1 and 2, 10 is an endless belt conveyor that rotates in the direction of arrow P, 11 is a vertically movable thin plate base, and this thin plate base 11 is the upper surface of a large number of thin plates 12 stacked on it. The height is controlled so that the height is approximately equal to the height of the upper surface of the belt conveyor 10. Further, the thin plate 12 is a rectangular one-way elongated rubber-coated thin iron plate, and is placed in a stack along the extension line of the belt conveyor 10.

A rodless cylinder 13 is horizontally provided above the belt conveyor 10 and the thin plate base 11 so as to straddle them, and is driven by the rodless cylinder 13 to slide in parallel with the belt conveyor 10. A horizontal slide base 15 is fixed to the slide block 14, and a first air cylinder (one elevating device) 16 and a second air cylinder (the other elevating device) 17 are attached to the horizontal sliding base 15 in front of the latter. They are arranged side by side so as to be positioned on the (belt conveyor 10 side), and the piston rods (elevating members) 16a and 17a face downward. Then, the suction pad 18 is attached to the tip of the piston rod 16a of the first air cylinder 16, and the pressing roller 20 is attached to the tip of the piston rod 17a of the second air cylinder 17 via the bracket 19. On the other hand, the supply roller 21 is provided so as to come into pressure contact with the upper surface of the belt conveyor 10 at a position slightly advanced from the supply side end 10a in the transport direction.

In the above structure, as shown by the solid line in FIG. 1, when the horizontal slide base 15 is located above the front part of the thin plate base 11, the piston rod 16a of the first air cylinder 16 is lowered and suction is performed. The uppermost thin plate 12 on the thin plate base 11 is adsorbed by the pad 18. Next, the suction pad 18 is raised, and the rodless cylinder 13 is driven to move the horizontal slide base 15 to the front end of the reciprocating stroke (see the chain line in FIG. 1). While dragging the uppermost thin plate 12, the front end thereof is pulled. Is conveyed to the vicinity of the end of the belt conveyor 10 on the supply side.

After that, the suction of the suction pad 18 is released, and at the same time, the second air cylinder 17 is actuated, and the pressing roller 20 is lowered through the piston rod 17a, so that the thin plate 12 is transferred to the belt conveyor 10. When it falls, the front portion of the thin plate 12 is pressed onto the belt conveyor 10 by the pressing roller 20, and the thin plate 12 is conveyed by the belt conveyor 10. Then, when the front end of the thin plate 12 reaches the supply roller 21 and enters below the supply roller 21, the front end of the thin plate 12 is pressed by the supply roller 21 onto the belt conveyor 10 and conveyed. Therefore, the horizontal slide base 15 is returned to the thin plate base 12 after the pressing roller 20 is pulled up.

In the above embodiment, the rodless cylinder 13 that reciprocates the horizontal slide base 15 can be replaced by any device such as a normal air cylinder, a feed screw, or a chain transmission device. Further, the air cylinders 16 and 17 as the one and the other lifting devices can be replaced with electromagnets. Further, in the above embodiment, the suction pad 18 is arranged on the rear side and the pressing roller 20 is arranged on the front side with respect to the conveying direction of the thin plate 12, but the suction pad 18 is arranged on the front side and the pressing roller 20 is arranged on the rear side. Alternatively, the suction pad 18 and the pressing roller 20 may be arranged side by side in the width direction when the width of the thin plate 12 is wide. Further, the belt conveyor 10 may be another conveyor such as a roller conveyor. It is also possible to install another conveyor that moves intermittently at the position of the thin plate table 11 to transfer the thin plate 12 from one of the two conveyors to the other, and in this case, the other conveyor at rest is It becomes a thin plate stand.

[0014]

[Effect of device]

 As described above, in the invention described in claim 1, the thin plate base is arranged in series on the supply side of the thin plate conveyor, and the horizontal direction is provided between the supply side end of the conveyor and the upper part of the thin plate base. Since two lifting devices are installed side by side on the slide table, one lifting device lifts the suction pad, and the other lifting device lifts the pressing roller. It is possible to suck the front part of the upper thin plate, convey the thin plate to the conveyor side by dragging, and then press the front part of the thin plate onto the conveyor with a pressing roller to convey the thin plate. Therefore, it is only necessary to provide one suction pad for adsorbing the front portion of a thin plate that is long in one direction. Also, the suction pad can be moved so long as the front part of the thin plate is placed on the supply side of the conveyor.Therefore, the length of the mounting part of the thin plate and the moving distance of the horizontal slide table in the conveyor can be greatly increased. The installation area can be reduced.

According to a second aspect of the present invention, in the first aspect of the present invention, the supply side of the conveyor is provided with a supply roller in contact with the upper surface, and the lower position of the pressing roller and the suction pad on the conveyor is set to the supply side of the conveyor. Since it is set between the end and the supply roller, if the front end of the thin plate being conveyed by pressure contact of the pressing roller enters under the supply roller, pressure contact of the pressing roller becomes unnecessary. Before the half of the entire length of the thin plate is transferred to the upper position, the pressing roller is raised and the horizontal slide table is retracted onto the thin plate table, so that the number of transferred thin plates per unit time increases.
