1 is a view for explaining the technical idea of a rollback processing machine according to the present invention.

Referring to FIG. 1, the rollback processing machine 10 according to the present invention includes a processing roller 20, a pedestal 50, and an actuator 70 coupled to a frame 12 constituting a skeleton. At this time, the processing roller 20 and the pedestal 50, as shown in Figure 4, to form the breaking line 2 and the sealing line 3 on the vinyl sheet (1).

The processing roller 20 is positioned above the vinyl sheet 1 to be transported and installed to rotate, and the breaking blade 30 and the sealing blade for forming the breaking line 2 and the sealing line 3 on the outer circumferential surface thereof. 40) are sequentially installed to have the same outer diameter. Such a processing roller 20 is rotated once by an actuator 70 that generates a driving force by an operation signal of the control unit 100 as in the present embodiment (see FIGS. 2 and 3) to be described later. The breaking line 2 and the sealing line 3 are formed on the surface. The processing roller 20 can form a break line 2 and a sealing line 3 of various structures on the vinyl sheet 1 as shown in FIG. 4, which is a broken blade coupled to the work roller 20. This is achieved by changing the shapes of the 30 and sealing blades 40. Therefore, the rollback processing machine 10 according to the present invention is to replace the rollback of various forms by replacing only the processing roller 20 and the pedestal (50, in the embodiment of the present invention to be described later, such as Figure 6b) that is manufactured for each product It can be manufactured. Of course, if it is configured to replace the breaking blade 30 and the sealing blade 40 will be applicable to replace only these.

The pedestal 50 is positioned below the vinyl sheet 1 to be transported to correspond to the processing roller 20 so as to be angularly moved with respect to the conveying direction of the vinyl sheet 1, and when the processing roller 20 is rotated. The angular movement in the conveying direction of the vinyl sheet 1 which is brought into contact with the breaking blade 30 and the sealing blade 40 is returned to the initial position. In the present invention, the pedestal 50 does not use the driving of the actuator 70 unlike the processing roller 20. Such a pedestal 50 has a fracture blade 30 when the fracture blade 30 or the sealing blade 40 contacts the vinyl sheet 1 when the processing roller 20 is operated (rotated) by the actuator 70. Alternatively, the sealing blade 40 is angularly moved in the conveying direction of the vinyl sheet 1 while supporting the vinyl sheet 1 to be compressed. In this state, the pedestal 50 is angularly moved in the conveying direction of the vinyl sheet 1, and then the broken blade 30 or the sealing blade 40 falls back from the vinyl sheet 1 to return to its original position. Accordingly, the pedestal 50 is set to have an outer diameter such that the pedestal 50 has the same contact path as the outer diameters of the breaking blade 30 and the sealing blade 40.

This pedestal 50 is configured to support the fracture blade 30 and the sealing blade 40 by installing the support cover 56 as a whole on the upper surface of the pedestal 50 as shown in Figure 6a or as shown in Figure 6b Likewise, it may be possible to separately configure the breaking blade holder 56 'and the sealing blade bearing 56 "on the pedestal 50. In this case, the breaking blade 30 and the sealing blade 40 are separately installed. The outer diameter may be set so that the 30 and the broken blade holder 56 'and the sealing blade 40 and the sealing blade holder 56 "have the same contact path as described above. And since the broken blade 30 is configured to partially cut the vinyl sheet 200, the structure of the broken blade 30 and the broken blade support 56 'conventionally applied may be applied as it is. For example, as shown in Figure 6a, the fracture blade support 56 'can be installed separately by high frequency heat treatment of the iron sheet is a rubber sheet. Such a configuration is omitted since it is a configuration that can be easily applied from the prior art.

The configuration for returning the pedestal 50 to its original position may be applied to various mechanisms applied in general mechanical technology. For example, in the present embodiment described later, as shown in FIGS. 2 and 3, one end of the spring 60 is fixed to the frame 12 and the other end of the spring 60 is fixed to the spring fixing plate 58 coupled to the bottom of the pedestal 50. By returning to the original position by the elasticity of the spring, but other forms of technology other than the spring structure can be easily applied.

As described above, the rollback processing machine 10 according to the present invention is configured to process a rollback by using one processing roller 20 and a pedestal 50 corresponding to the processing roller 20, unlike the conventional rollback processing machine. Therefore, the rollback processing machine 10 according to the present invention is a relatively simple configuration compared to the conventional rollback processing machine. Therefore, the rollback processing machine 10 according to the present invention is not only easier to manufacture than the conventional rollback processing machine, but also easy to maintain, and, if necessary, the rollback of another form by replacing only the processing roller 20 and the pedestal 50. As a result, the production of small quantities of various varieties becomes more convenient.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, FIGS. 2 to 6B, and like reference numerals denote like elements for performing the same function in FIGS. 1 to 6B. On the other hand, in the drawings, the illustration of the configuration and operation that can be commonly known to those skilled in the art from a general rollback processing machine is briefly omitted or omitted, and shown around the parts related to the present invention. In particular, there are parts where the size ratio between the elements is somewhat different or the sizes between the components coupled to each other are different, but the difference in representation of the drawings is easily understood by those skilled in the art. A separate description is omitted.

2 is a view for explaining a rollback processing machine according to a first embodiment of the present invention, Figure 3 is a view for explaining a rollback processing machine according to a second embodiment of the present invention.

That is, when the feed roller 90 and the processing roller 20 are applied using one actuator, that is, the driving motor 72 as in the former, the manufacturing cost can be lowered. In the case of applying the first drive motor 80 and the second drive motor 82, the manufacturing cost is slightly higher, but there is an advantage that can produce a rollback of a shorter length than the former case. That is, the former has a limit of the minimum machining length due to the rotational parallax of the fracture blade 30 and the sealing blade 40. When the two actuators are applied as in the latter, the limit of the minimum machining length due to such rotational parallax is further limited. You can take less. Of course, the former can also produce a rollback of a shorter length than the conventional method using a roller.

The break length controller 102 is installed in the control unit 100, and the encoder 110, the position sensor 120, the setter 122, and the like are installed in the control element 100 configured as described above.
