In the drawing, the unexplained symbol 1 represents an example of an adsorption object, and more specifically, is a bag having an open inlet.

The operation of the vacuum pressure cylinder for material adsorption according to the present invention configured as described above is described as follows.

The vacuum pressure cylinder 100 according to the present invention is installed on both sides of the target device (omitted from the drawing).

The vacuum pressure cylinder 100 is a fixed installation of a fixing bracket 70 on the cylinder body 10, between the fixing groove 71 of the fixing bracket 70 and the axial support groove 13 of the cylinder body 10. A fixed support shaft 60 is installed on the target device side.

In addition, the role of the support shaft 60 is to block the fourth air passage (A4) formed in the shaft support groove 13 and the fifth air passage (A5) communicating with the cylinder inner diameter portion 11, thereby allowing the fourth air to flow when pneumatic pressure is generated. Vacuum pressure can be induced to the cylinder inner diameter 11 through the flow path A4 and the fifth air flow path A5.

As described above, the vacuum pressure cylinder 100 installed in the form of hanging on the support shaft 60 through the fixing bracket 70 is transported by the forward and backward movements of the cylinder shaft 20 by the given vacuum pressure or release of the vacuum pressure. It is applied to the operation of equally adsorbing and opening the two sides of the entrance of the bag (1), which is an adsorption object, on each side, or to adsorb and move the object through the uniform operation of a plurality of vacuum pressure cylinders arranged in a row. It can be performed in various ways, such as an operation to move to the next process while maintaining the state.

Looking at the operation of the vacuum pressure cylinder 100 as described above, in the cylinder body 10, the cylinder body 10 is supplied with a suction force given through the hose connector 2 connected to the pneumatic hose in the first air passage A1. ) When negative pressure is formed inside, the negative pressure generated at this time is connected to the fourth air passage (A4), the fifth air passage (A5) and the cylinder cover (30) connected to the first air passage (A1) of the cylinder body (10). Pressure is applied to the cylinder inner diameter (11) through the ) side guide groove (32b).

At this time, the negative pressure generated in the cylinder inner diameter portion 11 pulls the cylinder shaft 20, which is guided to the cylinder inner diameter portion 11 of the cylinder body 10, into the negative pressure and moves forward as shown in Figure 7 attached.

The cylinder shaft 20 moves forward while the first shaft portion 21 is guided to the cylinder inner diameter portion 11, and at this time, the space between the second shaft portion 22 of the cylinder shaft 20 and the cylinder inner diameter portion 11 This is gradually reduced, and from this point on, more suction force is generated on the suction cup (20-1) through the rear end hollow of the cylinder shaft (20) advanced through the pneumatic adjustment inner diameter portion (12) through the first air passage (A1). This makes it possible to adsorb the bag (1) through the suction cup (20-1).

The cylinder shaft 20 advanced as described above is advanced along the guide hole 32a formed in the coupling shaft portion 32 of the cylinder cover 30, and the cylinder shaft 20 in the fully advanced state is the cylinder cover. When it touches the coupling shaft portion 32 of (30), no further forward movement is achieved.

As described above, the pneumatic adjustment bolt 40 screwed to the second air passage A2 of the cylinder body 10 by the forward motion of the cylinder shaft 20 and the third shaft portion 23 of the cylinder shaft 20 It is operated by tensioning a tension spring 50 connected at both ends as a support member 52.

The vacuum pressure generated during the above operation is stronger than the tensile force of the tension spring 50, and the forward movement of the cylinder shaft 20 is performed as described above.

In addition to the forward motion of the cylinder shaft 20, the cylinder inner diameter portion 11 and the extended pneumatic pressure adjustment inner diameter portion 12 are generated through the third air passage A3 connected to the first air passage A1. The negative pressure generates a suction force at the tip of the suction cup 20-1 coupled to the third shaft portion 23 through the hollow portion of the cylinder shaft 20, so that the suction cup on the cylinder shaft side advanced as described above is connected to the object. The object is adsorbed and pulled with a degree of suction force given by the backward motion of the cylinder shaft.

The above operation adsorbs an object through one or more vacuum pressure cylinders 100 installed on an automated process line, and restores the cylinder shaft 20 by restoring the tension spring 50, which has a higher elasticity than the suction force of the adsorbed object. While moving backwards, it is possible to repeatedly perform a vacuum pressure release operation in which the suction cup (20-1) falls from the bag (1) adsorbed on the suction cup (20-1).

For example, in the case of vacuum pressure cylinders 100 arranged on both sides or a plurality of vacuum pressure cylinders arranged in a row as described above, if one of them has poor adsorption power or, conversely, too strong adsorption occurs, the cylinder body (10 By adjusting the vacuum pressure as described above to the degree of screwing of the pneumatic pressure adjustment bolt 40 on the ) side, the normal operation of the vacuum pressure cylinder 100 can be realized by finely adjusting the uniform adsorption force, adsorption and retraction of the object, etc. You can.

As shown in FIG. 8, the pneumatic control bolt 40 has a conical and sharp end, so that its tip is in contact with the third air passage A3 connected to the first air passage A1. Accordingly, the vacuum pressure can be finely adjusted, and as a result, the cylinder shaft 20 moves forward as described above, and the volume within the cylinder inner diameter portion 11 decreases, and the cylinder through the pneumatic adjustment inner diameter portion 12 The degree to which an object can be adsorbed and released can be adjusted by adjusting the suction force generated through the internal hollow of the shaft 20.

The above adjustment can precisely adjust the vacuum adsorption force, the adsorption time, and the backward movement following release of the cylinder shaft from the object.

Ultimately, in the vacuum pressure cylinder according to the present invention, when vacuum pressure is formed through one pneumatic hose from one cylinder body in which each air flow path is formed in various ways, the volume change of the cylinder inner diameter portion 11 due to the forward motion of the cylinder shaft and At the same time, the vacuum pressure on the first air passage (A1) side adsorbs the object through the suction cup (20-1) on the cylinder shaft (20) side through the pneumatic pressure adjustment inner diameter portion (12), and releases the vacuum in the state of adsorbing the object. is a repetitive motion that is naturally released by the elastic force of the tension spring 50, and its structure is simple compared to the adsorption device of the existing vacuum pressure cylinder.

These vacuum pressure cylinders have a simple structure, so they are excellent in manufacturability, and offer the advantage of controlling the adsorption force through maintenance and fine pneumatic adjustment during use.
