Description

[Detailed Description of the Invention] The present invention relates to a gripping tool for roof tile blanks that sucks and takes out roof tiles pressed by a molding machine.

Conventionally, as a gripping tool for roof tile base material, a large number of suction holes are bored in the bottom plate of an air chamber sealed by a bottom plate and a side plate of a hollow substrate having a shape whose bottom surface conforms to the curved surface of the surface of the tile base material. There are gripping tools that fit each suction cup into each suction hole so that they are almost perpendicular to the curved surface shape of the surface of the tile base that grips each suction cup. At the same time, the bottom plate constituting the air chamber must be formed, and gripping tools for the bottom plate must be manufactured in various shapes to match the surface shapes of the roof tiles, resulting in high costs.

In view of the above-mentioned drawbacks, the present invention has been developed by drilling a communication port on the top surface of the hollow substrate attached to the gripper mounting bracket of the Japanese tile molding machine, connecting it to the suction device with a flexible tube, and connecting it to the bottom plate and side plate of the hollow substrate. A sealed air chamber is formed, the bottom plate is made flat, a number of holes are drilled therein, a pipe body is vertically fixed to the holes, a suction cup is attached to the lower end of the pipe body, and the pipe body is The bending was adjusted so that the suction cup was approximately perpendicular to the surface of the roof tile to be sucked, and the suction cup was formed into an elongated shape via a long plate-shaped mounting plate extending in the longitudinal direction of the upper surface of the roof tile. In an attempt to solve the above-mentioned drawbacks by providing a gripping tool for roof tile material, one embodiment of the present invention will be described below based on the drawings. The substrate 3 is fixed, and a sealed air chamber 6 is formed by the side plates 4, 4' and the bottom plate 5 of the hollow substrate 3. A fitting 8 for the flexible tube 7 is fixed to the upper central surface of the plate 2. A communication port 9 communicating with the air chamber 6 is provided through the fixture 8.

The bottom plate 5 of the hollow substrate 3 is made flat and has a large number of holes 10, 10'...
The upper ends of the pipe bodies 11, 11'... are fixed vertically to the pipe bodies 11, 11'..., and the lower ends of the pipe bodies 11, 11'... are provided with long plates extending in opposite directions in the longitudinal direction of the upper surface of the roof tile 12. shaped mounting plates 13, 13'... are fixed, and corresponding elongated suction cups 14, 14'... are attached to the lower surfaces of the mounting plates 13, 13'... with bolts 15, 15'... It is installed at

As shown in FIG. 1, the pipe bodies 11, 11'... are bent so that they are approximately perpendicular to the curvature of the upper surface in the transverse direction of the roof tile 12 to be adsorbed,
In addition, as shown in FIG. 2, the mounting plates 13, 13' are slightly bent to fit along the upper surface of the roof tile 12 in the longitudinal direction, so as to achieve an adsorption effect on the roof tile 12. There is.

In the figure, 16, 16'... are mounting bolts for attaching the gripper main body 1 to the gripper mounting bracket of a Japanese tile molding machine (not shown), 17 is a hole punching needle for penetrating a nail hole into the roof tile, 18 Limit switch for checking objects, 19
is a mark for stamping.

In the gripper according to the present invention, the gripper body 1 is positioned at right angles to the roof tile 12 press-molded by a Japanese tile molding machine, and the gripper main body 1 is positioned at right angles to the roof tile 12 press-molded by a Japanese tile molding machine. If the gripping tool main body 1 is operated so that it comes to the roof tile position, the flexible tube 7
are connected to a suction device (not shown), so that the suction cups 14, 14' attached to the lower ends of the pipe bodies 11, 11' of the gripping tool body 1 are approximately perpendicular to the surface of the roof tile 12 to be suctioned. When the roof tile 12 is located at the position, the roof tile 12 is vacuumed by a suction device and taken out from the Japanese tile molding machine.

In short, the present invention has a communication port 9 drilled in the upper surface of the hollow substrate 3 attached to the gripper mounting bracket of the Japanese tile molding machine, and connected to the suction device with the flexible tube 7. , 4' form a sealed air chamber 6, and the bottom plate 5 is made flat and has a large number of holes 1.
Pipe bodies 11, 11'... are fixed vertically into the holes 10, 10'..., and suction cups 14 are attached to the lower ends of the pipe bodies 11, 11'... 1
4'..., and the pipe bodies 11, 11'...
The pipe body 11, 11' is bent so that it is approximately perpendicular to the surface of the roof tile 12 to be adsorbed, so that the pipe body 11, 11' can be bent to fit the diversifying surface shapes of the roof tile 12.
Various types of roof tiles 12 can be assembled by simply bending the roof tiles 10 so that they are approximately perpendicular to the roof tiles 10 to be adsorbed.
We can provide a gripper main body 1 that matches the surface shape of the
Also, the pipe body 1 can be used to change the roof tiles 12 to be adsorbed.
This can be easily dealt with by simply adjusting the bending angles 1, 11', . . . .

In addition, a mounting plate 13 in the form of a long plate with suction cups 14, 14'... extended in the longitudinal direction of the upper surface of the roof tile 12,
Since it is formed into an elongated shape through the suction cups 13', the number of suction cups 14, 14', etc. can be reduced, and the number of pipe bodies 11, 11', which support the suction cups 14, 14', can be reduced. It is possible to reduce the volume of the hollow substrate 3, thereby making it possible to reduce the weight of the gripper body 1, and also to reduce the weight of the roof tile 1.
This has great practical effects, such as being able to significantly reduce the effort required to adjust the fit to the top surface.
