Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for suspending and transporting plate-shaped bodies one by one.

[Conventional technology]

Conventionally, when transporting a smooth-surfaced plate-shaped object, such as a glass plate, by suction, an appropriate number of suction pads are adsorbed in close proximity to the glass plate, and each sheet is lifted and transported. On the other hand, if the plate surface has an uneven surface, there is a risk of it falling due to the suction limit of the suction pad.
Suspension with hooks and suction pads that hold the end of the plate-like object and prevent it from falling, using multiple claws facing each other that swing horizontally and vertically with the action of a link whose tip is fixed. A conveyance vacuum hoist is known from Japanese Utility Model Publication No. 56-29308.

[Problem that the invention attempts to solve]

The above-mentioned vacuum hoist is sufficient for suspending and transporting mass-produced products whose plate sizes are specified, but vacuum hoists of various sizes, such as spacer frames made of two sheets of glass Double-glazed glass, which is glued on both sides and filled with sealant around all four sides, is heavy and comes in a relatively wide variety of sizes, and in the manufacturing process, the bonded parts are not yet cured. Vacuum hoists that use suction methods or have fixed claws have the disadvantage of being difficult to deal with, such as misalignment of the upper and lower glass sheets due to inclination during suction transportation, or separation of the lower glass sheet from the adhesive surface. Ta.

[Means for solving problems]

In order to eliminate the drawbacks of the above-mentioned prior art, the present invention
In a suspension conveyance device for a plate-shaped object, the device includes a plurality of sub-beams perpendicular to both sides of a main beam suspended on a hoist crane, and pads and opposing claws are arranged at the bottom of each end of the sub-beams. A plate-shaped plate having a configuration in which a claw portion is disposed on a base that is movable along the sub-beam, and a drive mechanism is provided on the claw portion to reciprocate and slide the claw portion in the axial direction of the sub-beam. Consists of a suspended body transport device.

[Function] The present invention uses the above-mentioned configuration to set the position of the pad and the sliding range of the claw portion in advance, and attaches the opposing claw portions to the plate-shaped body that may impede the suction action, for example. Lowering the device suspended over the double glazing where the adhesive is in an uncured state, the pad rests on the edge of the glazing near the spacer frame, while sliding each pawl. It penetrates the lower edge of the double-glazed glass and is then lifted up by a hoist crane and transported to a predetermined position.

This will be explained below with reference to the drawings.

The drawings show an embodiment of the device according to the present invention; FIG. 1 shows a perspective view of the entire assembly, and FIG. 2 shows a partially omitted perspective view showing the relationship between the double-glazed glass and the hanging device. FIG. 3 is a perspective view of partially omitted structural members fixed to the back surface of the pedestal.

The device of the present invention, which is suspended from the upper suspension ring 2 of the power supply box 1 by the hook of a hoist crane (not shown), has a main beam 3 made of a square pipe welded to the lower surface of the power supply box 1, and slide frames 4 at both ends of the beam. A square pipe sub-beam 5 is installed perpendicular to the main beam 3 through the main beam 3, and the slide frame 4 is a hollow square pipe that connects the main beam 3
A screw hole is provided in the center of the upper surface, and the main beam 3 is fixed at a predetermined position using a washer 5' and a fixing screw 6. On both sides of each sub-beam 5, pedestals 7 having the same structure as the slide pedestal 4 are provided.
is inserted into the beam, and the movable pedestal 7 is fixed by a washer 5' and a fixing screw 6'. The pedestal 7 has a mounting seat 8 on one side thereof.
A linear motor 10 with a built-in pinion and a linear motion mechanism of the rack 9 as shown in FIG. and rail 11 below it.
The pad 12 is screwed onto the mounting seat 8' near the pad 12. The rail 11 superimposed on the mounting seat 8' is fitted with a sliding seat 13 that can freely slide along the rail. , so that the claws at both ends of the beam are facing each other. Furthermore, align the hole on the side of the claw part 14 with the hole on the connecting plate 15, screw it in with a bolt and nut, insert the screw provided at the tip of the rack 9 into the hole provided on the upper part of the connecting plate 15, and tighten the nut 9'. When tightened, the sliding seat 13 and the connecting plate 15 become integrated, and the claw portion 14 becomes slidable along the rail 11 by the operation of the rack 9. Further, the pedestal 7 is movable as described above, and the pedestal 7 has a mounting seat 8',
Claw portion 1 fixed via rail 11 and sliding seat 13
4 and the pad 12 can be integrally changed in position along the sub-beam 5.

In addition, a cushioning material 16 such as silicone rubber or Teflon is attached to the claw portion 14 that comes into direct contact with the glass, and a rubber material or the like is used for the pad 12 that comes into contact with the top surface of the glass to prevent scratches. However, if the pad 12 is replaced with a suction pad and connected to a separate vacuum source, it is also possible to switch to a vacuum hoist.

The operation of the present invention will be explained below.

A plate-shaped object suspension and conveyance device suspended from a hoist crane adjusts the position of pads 12 on both sides of each sub-beam 5 to double-glazed glass 17 on a table (not shown).
The width of each sub-beam 5 is adjusted in advance so that each claw part 14 at both ends of the sub-beam 5 can be attached to the double-glazed glass 17, and the pad is brought into contact with the glass.

Next, when the linear motors 10 are driven simultaneously, the racks 9 whose sliding distances have been set in advance by a limit switch (not shown) are activated all at once, and the claws 14 connected to the racks are connected to each other via the connecting plate 15.
slides along the rail 11 with the sliding seat 13 and enters the lower part of the edge of the double-glazed glass 17, but before the edge of the plate glass and the side surface of the claw part 14 come into contact, the sliding distance is automatically set. After that, the hoist crane is used to lift the suspension device and transport it to a predetermined position.

[Effect of idea]

In this invention, the pads and claws are placed adjacent to each other on a positionable pedestal at each end of the sub-beam.
It can be applied to plate-shaped objects of various sizes,
The claw part that can slide freely along the sub-beam ensures horizontal hanging, so the product can be transferred without deforming it, and the installation position of the pad and the claw part, as well as the sliding distance of the claw part, are constant, so the plate-shaped object can be easily suspended. It is easy to position the pad that comes into contact with the pad, and furthermore, the suction type of suspension can be easily switched, which brings about significant practical effects.
