Description

[Detailed Description of the Invention] The present invention relates to a material support device for supporting a plate-shaped material.

Conventionally, on a table such as a press brake, a ball caster for smoothly moving a plate-shaped material and an electromagnetic magnet for adsorbing and fixing the plate-shaped material are attached. The upper part of the mold was flush with the upper surface of the lower mold.

Therefore, in the past, slipping occurred between the lower surface of the material and the upper surface of the lower mold and the upper surface of the electromagnetic magnet.

The above-mentioned slippage does not pose much of a problem when moving the material when it is thin and light, but when the material is thick and heavy, the frictional resistance increases and a large amount of power is required to move the material.

The present invention was created in view of the above-mentioned conventional problems, and a preferred embodiment of the present invention will be described in detail below with reference to the drawings.

The material support device 1 according to the present invention is attached to a table 3 of a plate processing machine such as a shearing machine or a press brake via bolts 5 or the like.

The workpiece support table 7 in the workpiece support device 1 has an inverted U-shaped cross-sectional shape including an upper surface 7a and both legs 7be7c.

The workpiece support table 7 is equipped with an appropriate number of workpiece suction and fixing devices 9 that can freely suction and fix the workpieces W.

The workpiece suction and fixing device 9 is made of, for example, a vacuum cup or an electromagnet, and has the function of suctioning and fixing the workpiece W.

The workpiece suction and fixing device 9 is mounted on a support plate 11 supported by both legs 7b and 7c of the workpiece support table 7, and its upper part 9a has a hole bored in the upper surface 7a of the workpiece support table 7. It protrudes slightly upward from 13.

Therefore, the workpiece W on the workpiece support table 7 can be suctioned and fixed by activating the workpiece suction and fixing device 9.

The workpiece suction and fixing device 9 acts after the workpiece W has been appropriately positioned to suction and fix the workpiece W so that it does not move, and is brought into a non-operating state at an appropriate time, such as after the start of machining or the end of machining of the workpiece W. This releases the suction fixation of the workpiece W.

The workpiece support table 7 is further equipped with an appropriate number of anti-friction devices 15.

The antifriction device 15 functions to reduce frictional resistance so that the workpiece W can be transferred smoothly when the workpiece W is transferred. It is.

That is, in this embodiment, a swinging body 19 having a ball caster 17 as an anti-friction device 15 mounted on its upper surface is mounted on the workpiece support table 4 so as to be swingable in the vertical direction.

Therefore, when the rocking body 19 is rocked upward, the antifriction device 15 protrudes from the upper part 9a of the workpiece suction and fixing device 9 to support the workpiece W, as shown by the solid line in FIG.

Therefore, the workpiece W is smoothly transferred without rubbing the upper part 9a of the workpiece suction and fixing device 9.

It should be noted that when the rocking body 19 is rocked downward, the upper part of the anti-friction device 15 is recessed into the upper part 9a of the workpiece suction and fixing device 9, as shown partially in phantom lines in FIG.

Therefore, the workpiece W comes into contact with the upper part 9a of the workpiece suction and fixing device 9, and the workpiece W can be reliably suctioned and fixed by the workpiece suction and fixation device 9.

The rocking body 19 has an inverted U-shaped cross section,
One end of the swinging body 19 is pivotally supported by a pivot 21 supported by both legs 7b and 7e of the workpiece support table 7.

The other end of the rocking body 19 is a free end, and is supported by a support arm 23.

The base of the support arm 23 is supported by a hinge pin 25 supported by both legs 7b and 7c of the workpiece support table 7, and the tip of the support arm 23 has a base near the other end of the swinging body 19. A supporting shaft 29 rotatably supporting a supporting roller 27 is attached.

Therefore, by appropriately swinging the support arm 23, the swinging body 19 swings in the vertical direction.

Note that each support arm 23 is connected to a connecting rod 31 so as to be interlocked with each other.
A swing working device 33 is mounted at an appropriate position to swing the support arm 23 and swing the swing body 19 in the vertical direction.

The swinging working device 33 includes a cylinder 35 and the like, the base of which is supported by the pivot shaft 21, and a piston rod 37.
The tip of the support shaft 29 is threadedly connected to a prismatic portion formed in the center of the support shaft 29.

Therefore, by appropriately operating the cylinder 35, the support arm 23 can be swung appropriately.

In the above configuration, when the anti-friction device 15 is in the state of protruding from the upper part of the workpiece suction and fixing device 9,
When the workpiece W is placed, the workpiece W is supported without coming into contact with the upper part 9a of the workpiece suction and fixing device 9.

Therefore, even if the workpiece W is heavy, it can be easily transported and the workpiece W can be easily positioned.

After appropriately transferring and positioning the workpiece W, when the swinging work device 33 is activated to swing the swinging body 19 downward, the anti-friction device 15 moves the upper part 9a of the workpiece suction and fixing device 9.
More immersive.

Therefore, the workpiece W is attached to the upper part 9a of the workpiece suction and fixing device 9.

Therefore, by operating the workpiece suction and fixing device 9,
The work W will be reliably suctioned and fixed.

As can be understood from the above description of the embodiments, the gist of the present invention is as stated in the claims for utility model registration, and as is clear from the description, the workpiece support table is shaped like an inverted U. It has a cross-sectional shape of
A workpiece suction and fixing device that can freely suction the bottom surface of a plate-shaped workpiece.
The antifriction device that can freely protrude above the top surface of the workpiece suction/fixing device and the rocking body supporting the antifriction device are arranged inside the workpiece support table, and one end of the workpiece support table is connected to the table of the plate processing machine. It is removably fixed to the

Therefore, the workpiece can be reliably fixed by the workpiece suction and fixing device, and even if the workpiece is in close contact with the workpiece suction and fixation device, it can be reliably pushed up due to the support of the anti-friction device, and the workpiece can be moved smoothly. This can be done in the following manner.

Additionally, since each component is housed inside the workpiece support table, the overall configuration can be made more compact and unitized, and can be easily attached to the table of conventional sheet processing machines. It is something.
