The movable member 330 and the piston rod pair 340 inserted into the cylinder body 310 and coupled to the movable member 330 at one end to move the movable member 330 while moving back and forth by pneumatic pressure. may include

A guide member 331 for guiding the paper material S may be additionally provided at the front end of the feeding unit 300 .

10 is a perspective view showing the configuration of the feeding part of FIG. 1 from which the paper material is removed.

10, the mounting member 320 and the movable member 330 of the feeding unit 300 are provided with first and second passing slits 322 and 332 for passing the paper material S, respectively, and , the movable member 330 includes an arm 334 having an H-shape in plan view, a first transfer plate 336 horizontally coupled to the lower surface, and a second horizontally coupled end of the arm 334 . 2 may include a transfer plate 338 . In this case, the arm 334 may include first and second arm members 334a and 334b formed to be stepped. Here, the first transfer plate 336 and the second transfer plate 338 are not limited in shape, but may be formed in a rectangular shape, for example.

That is, the feeding part 300 includes a first transfer plate 336 coupled to the lower surface of the movable member 330 , and an end of the arm 334 , in particular, a second arm member of the arm 334 . The second transfer plate 338 coupled to the 334b has a structure in which it is transferred together.

The configuration of the arm 334, the first transfer plate 336, and the second transfer plate 338 serves to assist the multi-layered paper material S to be transferred while supporting the weight. have.

In addition, an auxiliary support plate 339 for assisting the transfer of the paper material S may be installed between the feeding unit 300 and the forming unit 400 .

Referring to FIG. 11 , the mount member 320 and the movable member 330 of the feeding part 300 are positioned at the front end of the molding part 400 .

Referring to FIG. 12 , an end of the second arm member 334b among the arms 334 of the movable member 330 spans the end of the mount member 320 . At this time, the movable member 330 is spaced apart from the cylinder body 310 by a predetermined distance by the piston rod pair 340 .

Referring to FIG. 13 , the movable member 330 is brought into contact with the cylinder body 310 by the pair of piston rods 340 , and accordingly, the arm 334 of the movable member 330 is moved together. At this time, the first transfer plate 336 coupled to the lower surface of the movable member 330, and the end of the arm 334, in particular, the second coupled to the second arm member 334b of the arm 334 The transfer plate 338 is transferred together. At this time, of course, the circular cut-out portion 410 of the forming portion 400 is in an elevated state.

As a result, the end of the second arm member 334b of the arms 334 comes close to just the front of the circular cutout 410 of the forming portion 400, and thus the second arm member 334b coupled to the second arm member 334b comes close to the end. 2 The paper material (S) is newly supplied over the lower part of the circular cutting part 410 by the transfer plate 338 so that it can be cut and processed.

Referring to FIG. 14 , the forming unit 400 includes a circular cutting unit 410 that can cut the paper material S in a circular shape, and is disposed below the circular cutting unit 410 and operates in a vertical direction.

The circular cutting unit 410 may be lifted up and down by the cutting unit driving unit 411 , and the paper material S may be supplied while the circular cutting unit 410 is elevated.

In addition, the circular cutting unit 410, when the first and second operation cylinders 210 and 212 of the tension control unit 200 operate, a predetermined time period so as to fix the paper material (S) It is configured to maintain a descending state during the period.

Accordingly, the first and second operating cylinders 210 and 212 can operate in a state in which the paper material S is fixed across the feeding unit 300 and the forming unit 400, and as a result, the paper material S ) has the advantage that tension control becomes easy.

Preferably, the forming part 400 discharges the waste paper S1 in the same direction as the supply direction of the paper material S, and the paper formed in a direction perpendicular to the direction in which the paper material S is supplied. The container may be configured to be evacuated.

15 is a photograph showing the direction in which the waste paper (S1) is discharged. Even without human intervention, the waste paper (S1) is automatically discharged after the processing of the paper container is completed and continuously accumulated in a waste means such as a sack. Therefore, it is easy to dispose of it later.

As shown in Figure 15b, the discharge of the lung paper (S1) is of course made when the circular cutting portion 410 is in the lifting position.

16 is a photograph showing the direction in which the molded paper container is discharged. A conveyor 500 is provided under the molding mold part 420 of the molding part 400 so that the molded paper container can be transported to a desired position. can be

Here, the molded paper container may be a plurality of paper containers. For example, if the paper material S is supplied in the amount of 20 sheets from the supply unit 100 , 30 paper containers may be molded and discharged in the molding unit 400 .
