Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin sheet handling device for supplying a resin sheet to a molding machine such as a vacuum molding machine.

[0002]

2. Description of the Related Art Conventionally, in a device for sucking and handling a resin sheet by a suction force, a mechanism for using a plurality of suction pads and providing a pipe for each suction pad and moving and adjusting the installation position of the suction pad has been proposed. Things are known. However, in this device, since the suction pad has to be moved when the size of the resin sheet changes, a considerable working time is required for the movement. The present invention has been made in view of the above problems, and an object thereof is to provide an apparatus capable of handling a resin sheet with a short adjustment time even when the size of the resin sheet changes. .

[0003]

In order to achieve the above object, a resin sheet handling apparatus according to the present invention forms a lower surface having a size corresponding to the maximum area of a resin sheet used in a molding machine main body. A suction head that defines a hollow chamber that communicates with the suction means, a plurality of suction ports that are arranged in a grid pattern on the lower surface of the suction head, and that are formed in communication with the hollow chamber, and a plurality of the suction ports. A plurality of manual slide valves provided in each of them, and a sheet-like seal attached to the lower surface of the suction head by opening a portion corresponding to the suction port. .

Embodiment 1 An embodiment of the present invention will be described in detail below with reference to the drawings. In FIG. 1 which is a schematic view showing a plan view of the present embodiment and FIG. 2 which is a schematic side view, an elevating table in which a resin sheet 2 is placed next to the molding machine main body 1 in an overlapping manner.
Bull 3 is provided. A frame 4 is provided so as to surround the elevating table 3, and rails 1a, 1a and a rail are provided on the upper portion of the molding machine body 1 and the frame 4, respectively.
4a, 4a are provided. Furthermore, the above-mentioned rail 4
A suction head 5 equipped with rollers 5a and 5a is placed on a and 4a, and the suction head 5 is provided between the molding machine main body 1 and the frame 4 surrounding the lifting table 3 by a conventional method. Actuator
It can be moved back and forth by the M. The lower surface of the suction head 5 has a size corresponding to the maximum area of the resin sheet 2 used.

FIG. 3 is an enlarged cross-sectional view of the portion A of FIG. 1, that is, the periphery of the suction port 5b, and FIG. 4 is a BB arrow view of FIG. In FIGS. 3 and 4, the suction head 5 defines a hollow chamber 5d therein and is provided with a plurality of suction ports 5b arranged on a lower surface in a grid pattern. The suction port 5
A manual slide valve 6 provided with a disc-shaped sluice valve 6a is provided on the upper side of b, and the opening 6b and the sluice valve opening 6c of the manual slide valve 6 are made to communicate with each other by turning a knob 7 or closed. be able to. The hollow chamber 5d inside the suction head 5 is connected to a suction blower (not shown) as suction means so that suction can be performed. Further, the disc-shaped sluice valve 6a of the manual slide valve 6 of the suction head 5 is
It can be opened and closed separately according to the size of the resin sheet 2 used for the molded product. On the lower surface of the suction head 5, a sheet-shaped seal 5c having an opening corresponding to the suction port 5b is attached. Furthermore, a clamp frame 1b corresponding to the size of the molded product is detachably provided in the molding machine body 1.

In the structure as described above, in FIG. 1, the manual slide valve 6 located in the central portion is opened due to the size of the resin sheet 2, and the manual slide valve located in the outer peripheral portion is opened. The valve 6 is set so as to be closed.
Next, the elevating table 3 rises to the point where the resin sheet 2 contacts the sheet-shaped seal 5c on the lower surface of the suction head 5. Then, the inner hollow chamber 5d of the suction head 5 is sucked by a suction blower (not shown), and the suction port 5b of the suction port 5b is opened through a manual slide valve 6 which is located at the central portion and opened depending on the size of the resin sheet 2. The lower air is sucked, and these suction ports 5b
The uppermost one of the resin sheets 2 stacked due to the pressure difference between the lower air and the outside air is pressed against the sheet-shaped seal 5c. After this, the elevating table 3 is lowered, and the suction head 5
The molding machine body 1 along the rails 1a, 1a, 4a, 4a.
Move to. After the suction head 5 is moved onto the clamp frame 1b, the inside of the suction head 5 is returned to the atmospheric pressure, and the resin sheet 2 is placed on the clamp frame 1b by its own weight. After the suction head 5 has returned to above the lifting table 3, the resin sheet 2
Is molded.

When the size of the resin sheet 2 is changed, the manual slide valve 6 located at the center is opened according to the size of the resin sheet 2, and the resin sheet 2 is opened. The manual slide valve 6 located on the outer peripheral portion of 2 is set so as to be in a closed state.

[0008]

As is apparent from the above description, the present invention forms a lower surface having a size corresponding to the maximum area of the resin sheet used in the main body of the molding machine, and internally forms a hollow chamber communicating with the suction means. A defined suction head, a plurality of suction ports arranged in a checkerboard pattern on the lower surface of the suction head and opened in communication with the hollow chamber 5d, and a plurality of manual slide valves for each of the plurality of suction ports, By having a sheet-like seal attached to the lower surface of the suction head by opening a portion corresponding to the suction port, there is no need for time-consuming work for moving the suction pad The effect is great.
