Abstract

PURPOSE:To facilitate the suction control by installing an opening/closing tool which is tilted by the approach and contact of a base box part with a work and can open the air passage of a suction device, in the state where a flat shaped work such as outer decoration plate and floor plate is sucked by the vacuum suction device and transported. CONSTITUTION:When a base box part 3 is approached to a work W on a table lifter by lowering the supporting plate 17 of a supporting frame which is shiftable in the vertical and horizontal directions, the height of a buffer member 7 for seal which contacts the upper surface of the work W is reduced (compressed) by the shock, and the undersurface of a roller 42 as one edge part of an opening/closing tool 5 contacts the work, and then an opening/closing plate 44 separates the opening/closing tool 5 from an opened port edge A, and then an air passage 9 is shifted to an opened state. In this opened/closed state, the air in the base box part 3 is vacuum-sucked from the opened port edge A by a sucking device 4, and the work W is sucked on the undersurface of the buffer 7 for seal. The sucked work W is lifted by the rise of the supporting plate 17, and transferred to a prescribed place.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work adsorbing device capable of opening an air path formed by a suction device by contacting a work with an opening / closing tool, thereby reducing costs and simplifying maintenance.

[0002]

2. Description of the Related Art For example, in order to convey a flat plate-like work such as an exterior plate or a floor plate attached to a frame of a panel body to a predetermined position in a factory, the work is adsorbed by a suction device connected to a vacuum pump. It often goes up and moves horizontally.

Conventionally, the open end of the suction device for vacuuming has been opened / closed by detecting the presence or absence of a work by using a sensor.

[0004]

However, in the conventional device in which the opening end of the suction device is opened and closed by using the sensor, a highly accurate sensor type detection device is used, which causes an increase in cost and a failure. The maintenance at the time of such became complicated, and the maintenance was made difficult.

The present invention is based on the fact that the air passage formed by the suction device is opened by the tilting of the opening / closing tool caused by the contact between the one end of the opening / closing tool and the work, and the cost and the maintenance can be simplified. The purpose is to provide an adsorption device.

[0006]

DISCLOSURE OF THE INVENTION The present invention is a work suction device which is arranged on a support frame which can be raised and lowered and horizontally moved and which sucks a plate-like work. The work suction device has a lower opening and a lower edge attached to the support frame. A base box part in which a cushioning material for sealing is continuously provided on the lower surface of the surrounding flange, and an opening end that opens in the base box part are provided, and an air path for drawing a vacuum from the opening end by connecting to a vacuum source is provided. An eggplant suction device and a lever-like member pivotally supported by the base box part, and one end of which is located below the lower edge of the base box part so that the other end closes the air passage and the work has a base box part. When approaching, the work and one end contact each other and tilt, and the other end opens and closes the air passage and an opening / closing tool for adsorbing the work.

[0007]

In the work suction device, one end of the opening / closing tool comes into contact with the work and tilts when the base box is lowered, thereby opening the air passage formed by the suction device. Therefore, by lowering the base box part and bringing it closer to the work, the inside of the base box part is evacuated from the opening end of the suction device, and the work can be adsorbed through the cushioning material provided on the lower surface of the flange of the base box part.

As described above, as compared with the opening / closing operation of the suction device by the sensor type detection signal, the structure thereof can be simplified, the cost can be reduced, and the maintenance in the case of a failure can be facilitated.

A rectangular support plate 17 is horizontally attached to the lower end of the rod of the cylinder 29, and the support plate 1
A pair of guide shafts 30, 30 for holding the cylinder 29 between them to prevent rotation are erected on the base plate 7 through the substrate 27.

The support frame 2 includes side plates 26 of the traveling table 16,
The wheels 25 are driven by the operation of the reduction motors M mounted on the wheel 26.
It is possible to horizontally move along the vertical frame members 22 and 22 by rotating, and to raise and lower the support plate 17 by the operation of the cylinder 29.

In the present embodiment, the base box portion 3 of the work suction device 1 is mounted side by side on the support plate 17 of the support frame 2, and as shown in FIG. It is in the shape of a box that is open at the bottom with 32 ... A horizontal flange 6 is continuously extended from the lower edge of the side plate 32, and a cushioning material 7 for sealing is continuously provided on the lower surface of the flange 6.

Vertical shafts 33 ... Having screw shafts 33A at their upper ends are raised from the four corners of the flange 6 of the base box 3, and the four shafts 33 ... The base box portion 3 is attached to the support plate 17 of the support frame 2 so as to be lifted up by screwing the nut 34 onto the screw shaft 33A that penetrates the hole provided in the support plate 17 and projects from the upper surface of the support plate 17. A spring 35 is wound around the shaft body 33 to prevent the base box portion 3 from being excessively lifted, while the support plate 17 is lowered and the lower surface of the sealing cushioning material 7 comes into contact with the upper surface of the work W. Alleviates the impact of.

On one side plate 32 of the base box part 3, a suction device 4 is provided.

Further, the support plate 17 of the support frame 2 is lowered,
When the base box part 3 is brought close to the work W on the table lifter 23, the height of the cushioning material 7 for sealing which abuts on the upper surface of the work W is reduced by the impact, and the roller 42 which is one end of the opening / closing tool 5 is reduced. The lower surface comes into contact with the work W to move the opening / closing tool 5 to the state shown in FIG. 4, that is, the open state Y in which the air passage 9 is opened by separating the opening / closing plate 44 from the opening end A.

In the open state Y, the suction device 4 evacuates the air in the base box portion 3 from the opening end A to suck the work W on the lower surface of the cushioning material 7 for sealing.

The adsorbed work W is lifted by the lifting of the support plate 17, and the traveling table 16 horizontally moves to transfer the work W to the belt conveyor 24.

The cushioning material 7 for sealing is further reduced in height in addition to the reduction in height due to the impact at the time of adsorption.
