Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended to attach various plate-like materials such as metal plates, synthetic resin plates, inorganic plates, and wood plates to various base materials. The present invention relates to a device for horizontally lifting a strip and then dropping it onto the upper surface of a substrate, and further pressing the plate against the substrate.

[Prior Art] One of the most common methods for decorating various substrates, rust prevention, corrosion prevention, airtightness, and the like is to stick a plate-like body on the surface of the substrate.

For example, when attaching a metal decorative plate to the surface of a lightweight cellular concrete panel (hereinafter referred to as ALC panel), while applying an adhesive to the upper surface of a horizontally placed ALC panel, a lifting and pressing device is used. The decorative plate is hoisted horizontally, then slowly dropped on the upper surface of the ALC panel, and the decorative body is pressed against the ALC panel.

Conventionally, as a device for performing both lifting and pressing operations of a plate-like body as described above, a suction pad for adsorbing the plate-like body is attached to a base body connected to a lifting mechanism, and a suction source is attached to the suction pad. Those that are connected are common.

[Problems to be Solved by the Invention] Even in the lifting and pressing device of the plate-like body, no particular problem occurs when the plate-like body sucked by the suction pad is lowered onto the upper surface of the base material by operating the elevating mechanism. .

However, when the plate-shaped body is further pressed against the base material, the plate-shaped body is pressed through the suction pad, which may damage the suction pad. There was a problem that I could not.

In particular, the decorative plate of the ALC panel described above has a width of 40 to 90 cm and a length of 60 to 400 cm, and some of them are very large.Therefore, a very large pressing force is required to securely attach the decorative plate. I need. Therefore, it is difficult to sufficiently press such a decorative plate by the conventional lifting and pressing device, and it is necessary to separately press the decorative plate using a pressing device or the like.

The purpose of the present invention is not only to lift the plate-shaped body, but also to press the plate-shaped body against the base material with a large pressing force without damaging the suction pad, and thus the plate-shaped body can be pressed. It is an object of the present invention to provide a novel plate-shaped body lifting and pressing device that can be reliably attached.

[Means for Solving the Problems] In order to achieve the above object, according to the present invention, a plate-shaped body is lifted at a first location to be moved to a second location, and a substrate placed at the second location. In a lifting and pressing device that lowers and presses the plate-shaped body on a material, a base body of the lifting and pressing device that can move up and down and a horizontal movement, and a floating extending in a horizontal direction attached to the base body so as to be vertically movable. Member, a suction pad attached to the lower surface side of the floating member so as to contact the plate-like body only by receiving the weight of the floating member, a suction source for generating a suction action on the suction pad, and the suction pad In order to be able to press the plate-like body adsorbed on the substrate, a horizontally extending pressing member is attached to the lower end portion of the connecting column extending downward from the base member through the floating member. .

[Operation] First, in the first place, the lifting mechanism is operated to lower the lifting and pressing device to the plate-like body. At this time, the floating member is lowered by its own weight, and the suction pad projects downward from the pressing member, so that it comes into contact with the plate-shaped body. When the suction source is operated in this state, the suction pad sucks the plate-shaped body. Then, the plate-like body can be lifted by operating the lifting mechanism to raise the lifting and pressing device.

Next, the lifting and pressing device is horizontally moved to a second location and positioned above the substrate. An adhesive is applied to this base material by a known means.

Then, the elevating mechanism is operated to lower the lifting and pressing device onto the substrate. When the plate member comes into contact with the surface of the base material, the floating member stops descending and only the pressing member continues descending, so that the floating member floats upward relative to the pressing member.

When the lifting and pressing device is further lowered and the pressing member comes into contact with the upper surface of the plate-shaped member, the pressing member presses the plate-shaped member against the base material with a large pressing force. At this time, only the weight of the floating member is applied to the suction pad.

When the lifting and pressing device 1 is subsequently lowered, as shown in FIG. 7, the floating member 7 is further floated relatively upward, and the stop limit switch L ₂ attached to the upper part of the floating member 7 is Working plate attached to the bottom of the base body 2
Since it comes into contact with 22 and turns on, the lowering of the elevating mechanism 1 is once stopped.

After confirming the above completion, the lifting and pressing device 1
And slowly lower it again. Then, as shown in FIG. 8, when the pressing member 4 comes into contact with the upper surface of the decorative plate 33, the pressing member 4 presses the decorative plate 33 against the ALC panel 31 with a large pressing force. It is securely attached to the panel 31.

Then, when the pressing limit switch L ₃ attached to the upper portion of the floating member 7 comes into contact with the action plate 23 attached to the lower portion of the base body 2 and turns on, the lowering of the elevating mechanism is stopped, and the relief valve V _0. Is opened and the suction of the decorative plate 33 by the basic suction pad 11 and the like is released, and the lifting mechanism further rises,
A series of pasting work is completed.

At this time as well, the self-weight of the floating member 7 (if the spring 9 is provided, the force obtained by subtracting the elastic force of the spring 9 from the self-weight) is applied to each of the suction pads 11 to 14, There is no risk of damage to the suction pads 11-14.

The present invention is not limited to the configuration of the above-described embodiment, and may be embodied by being arbitrarily modified within the scope not departing from the spirit of the invention as follows.

(1) The shape and structure of the pressing member is not limited as long as it can press the plate-shaped body substantially entirely, and may be divided into a plurality of plate-shaped, rod-shaped, or block-shaped members, for example.

Further, although the pressing member is connected to the elevating mechanism via the base body in the above embodiment, it may be directly connected to the elevating mechanism.

(2) The shape and structure of the floating member is not limited as long as it can support the suction pad and can float up and down, and may be, for example, an arm-shaped member or a divided member.

(3) Number and arrangement of basic suction pads and auxiliary suction pads
The interval and the like can be changed. It is also possible to omit the auxiliary suction pad and use only the basic suction pad.

(4) It can be embodied as a device for lifting and pressing various plate-shaped bodies other than the decorative plate of the ALC panel.

[Advantages of the Invention] Since the lifting and pressing device of the present invention is configured as described above, not only can the plate be lifted, but the plate can be used as a base material without damaging the suction pad. On the other hand, it is possible to press with a large pressing force, and thus it is possible to exert an excellent effect that the plate-shaped body can be reliably attached.
