Description

Cutting machine for gold foil {Cutting device for metal sheet}

The present invention relates to a cutting device for gold foil, and more particularly, to a cutting device for collectively cutting gold foil in a laminated state composed of a sheet.

In the modern industry, many kinds of film materials are used in various fields. In general, these film materials are wound in roll form during production.

In the actual use process, the wound film materials are released and used. At this time, since the film-like material is generally cut and used in a constant length or shape, a material obtained by repeatedly cutting the film-like material in a constant length or shape is used.

For cutting such film materials, film materials wound in a roll form are usually cut to a certain size using a mechanical cutter, and conventional mechanical cutters raise or lower a cutter having a blade corresponding to the overall width of the film materials, It is configured in various ways, such as cutting the film-like material by turning around one end of the cutter, or cutting the film-like material through a laser.

It is preferable that the configuration of the mechanical cutter is selected according to the type of the film material, and in particular, a fixing means for fixing the film material before cutting the film material is essential to cut a plurality of gold foil film materials at once.

In the case of gold foil film materials, since the film is relatively thin and has little friction due to a smooth surface, it is necessary to fix the film materials before cutting them to obtain correct results.

If the film-like material is not properly fixed before cutting the gold-film material, the laminated film-like materials cannot be cut at the correct position due to twisting of each other, and when the film-like material is cut in this state, multiple sheets of film-like material are in different directions. There was a problem in that the cut surface was formed and the productability was deteriorated.

For this reason, the conventional mechanical cutting machine for cutting the laminated gold foil film materials maintains a constant tension in the film materials or cuts the laminated gold foil film materials while controlling the supply speed of the film materials, but this is not suitable for mass production. As a method, productivity decreases, and in particular, it is not easy to handle a gold foil film material in a cut state, and thus it is not appropriate to immediately insert it into an additional processing process or packaging process after cutting the film material material, thus significantly reducing the worker's work efficiency. There was a problem with the rear.

The gold foil cutting device according to the present invention is largely as shown in Figures 1 to 4, each of a plurality of gold foil is wound, and the plurality of pieces of gold foil are combined and discharged, the supply part 100 and the gold part discharged from the supply part 100 It includes a deployment portion 400 for gripping one end to unfold the gold foil, and a cutting portion 200 disposed between the supply portion 100 and the deployment portion 400 and for cutting the gold foil developed by the deployment portion 400 in a batch. It can be defined as

First, the supply unit 100 is provided with a plurality of unit rollers 110 on which roll-shaped gold foil is mounted, and roll-type gold foil mounted on each of the plurality of unit rollers 110 is unwound and gathered in one place so that the lower side is On the lamination roller 120 is provided. When the roll-shaped gold foil is unwound and collected by the lamination roller 120, the gold foil is laminated in the form of a sheet to be discharged forward.

On the other hand, this embodiment describes an example in which a plurality of sheets of gold foil are mounted on the supply unit 100, but one sheet of gold foil may be mounted on the supply unit 100 and discharged toward the cutting unit 200.

Next, the cutting unit 200 is disposed in front of the supply unit 100 and receives the laminated gold foil discharged from the supply unit 100 and serves to cut it.

The cutting part 200 is, for example, a seating plate 210 on which a gold foil is seated, a first pressing member 220 pressing the gold foil seated on the seating plate 210 from the top, and the first pressing member 220 The second pressing member 230 which is disposed on the rear side and presses the gold foil seated on the seating plate 210 from the top and the cutting member 240 which cuts the gold foil in a direction perpendicular to the direction in which the gold foil is deployed, and the Illustrates to include a support plate 250 spaced apart from the top of the seating plate 210.

The first pressing member 220 and the second pressing member 230 provide a pressing force toward the gold foil seated on the seating plate 210 while being supported by the supporting plate 250.

When the gold foil is seated on the seating plate 210, the first pressing member 220 and the second pressing member 230 operate to press the gold foil seated on the seating plate 210 from the top. Since the laminated urgent paper is cut by the cutting member 240 in the state pressed by the first pressing member 220 and the second pressing member 230, cutting can be performed in a state where the lamination state of the gold foil is firmly maintained. have.

That is, since the laminated gold foil is pressed before the cutting occurs, there is no fear that each of the sheets of gold foil is separated from each other or slipped, and thus, the cut surfaces of each of the plurality of cut gold foils are always matched.

If, when cutting a sheet of gold foil, and cutting without sufficiently fixing them, the cutting surface of the gold foil cannot be uniformly formed. For example, as shown in FIG. 11, the cutting surface S of the gold foil M is not horizontal, but the cutting surface S is inclined in an irregular direction, or a specific portion around the cutting surface S is completely damaged, so that the productability is remarkable. Can fall.

Next, the cutting member 240 is characterized in that the gold foil is cut in the width direction (left and right directions). To this end, the cutting member 240 includes a cylinder body 241 mounted on the support plate 250, a guide block 242 reciprocating in the left and right directions from the cylinder body 241, and the guide block 242. It may be defined as including a cutting blade 243 extending downwardly installed.

The cutting member 240 is driven in a state where the first pressing member 220 and the second pressing member 230 press the gold foil. At this time, the cylinder body 241 may be embodied as a structure of an oil or pneumatic cylinder, and the guide block 242 is reciprocated in the left and right directions depending on whether the working fluid is operated. Accordingly, the cutting blade 243 is moved together to cut the gold foil seated on the seating plate 210.

Although not shown, a guide rail for smooth driving of the guide block 242 may be formed at a connection point between the cylinder body 241 and the guide block 242. In addition, the cutting blade 243 is preferably mounted on the guide block 242 via the blade holder 244, and the cutting blade 243 is formed on the blade holder 244 to form a detachable structure. ).

Next, the first pressing member 220 provides reciprocating driving force to the first pressing plate 221 and the first pressing plate 221 that are reciprocated in the up and down direction between the support plate 250 and the seating plate 210. It may be defined as including a first pressurized actuator (not shown).

The first pressure plate 221 is moved up and down by the driving of the first pressure actuator to selectively press the gold foil seated on the seat plate 210.

As shown in FIG. 6, the blade movement spaces 211 and 221a through which the cutting blade 243 passes are formed through the seating plate 210 and the first pressing plate 221, respectively. The blade movement spaces 211 and 221a are provided in the form of a long groove extending in the left and right directions to ensure reciprocating movement of the cutting blade 243 left and right.

When the guide block 242 reciprocates in the left and right directions, the cutting blade 243 is reciprocated in the left and right directions along the blade movement spaces 211 and 221a accordingly, and the seating plate 210 and the first pressing plate ( 221) The interposed gold foil is cut.

The receiving plate 210 and the first pressing plate 221 may be formed with tip receiving portions 212 and 221b which are cut out from the central portion of each blade moving space 211 and 221a forward. The gripping jaws 410 of the deployment portion 400, which will be described later, approach the tip receiving portions 212 and 221b to grip one end of the gold foil.

Next, the second pressing member 230 is made of a similar to the first pressing member 220, in particular, is disposed behind the first pressing member 220 and is operated by placing a time difference from the first pressing member 220 There are features.

The second pressing member 230 is reciprocated in the up and down direction as shown in FIG. 4 to provide a reciprocating driving force to the second pressing plate 231 and the second pressing plate 231 to selectively press the gold foil. It may be defined as including a pressure actuator (232).

The second pressing plate 231 is moved up and down by the driving of the second pressing actuator 232 to selectively press the gold foil seated on the seating plate 210.

That is, since the first pressing member 220 and the second pressing member 230 press the gold foil at the same time, the fixing force of the gold foil is generated at two points, so that the cutting can be performed in a state where the pieces of gold foil are tightly adhered to each other.

Examples of the time difference operation of the first pressing member 220 and the second pressing member 230 will be described later.

The seating plate 210, the first pressing plate 221, the second pressing plate 231, etc. are preferably embodied in a plate shape so as to press the gold foil with a uniform area and do not form wrinkles on the gold foil.

On the other hand, the gold foil cutting device according to the present invention is disposed between the cutting part 200 and the deployment part 400 so that the cut gold foil is discharged and settled, and further includes a discharge part 300 having a moving passage 310 in the center. can do.

The gold foil discharged from the supply unit 100 is expanded to the upper surface of the discharge unit 300, and a part of the gold foil is cut by the cutting unit 200 to be seated on the upper surface of the discharge unit 300.

When the gold foil in the cut state is settled on the upper surface of the discharge unit 300, the user removes the gold foil from the upper surface of the discharge unit 300 to insert the gold foil into a separate packaging unit, and is usually thicker than the gold foil to maintain the shape of the gold foil. The high hardness base paper (BP) is put together in the packaging unit.

At this time, in the process of removing the gold foil from the upper surface of the discharge unit 300, there is a fear that the positions of the gold foils of the sheets are shifted to each other.

To prevent this, a guide surface 320 for guiding the access of the base paper BP is provided on one side of the upper end of the discharge unit 300 to guide the state of the cut sheet gold foil to the upper surface of the base paper BP. Is formed.

As illustrated in FIG. 7, when a part of the edge of the gold foil is exposed by the guide surface 320 and the edge of the base paper BP is approached along the guide surface 320, the user may directly cut the sheet of gold foil by hand. The gold foil is naturally merged with the base paper BP without having to be removed from the upper surface of the discharge part 300, so that it can be put into a packaging unit. The guide surface 320 is preferably formed by round processing.

The movement passage 310 is utilized as a passage for the gripping jaw 410 of the deployment part 400 to be described later to reciprocate.

Next, the deployment unit 400 expands the gold foil discharged from the supply unit 100 to the upper surface of the discharge unit 300, and also contributes to the formation of the tension section S1 of the gold foil.

To this end, the deployment unit 400 includes a gripping jaw 410 for gripping the upper and lower sides of the gold foil, and a deployment actuator for reciprocating the gripping jaw 410 forward and backward within the movement passage 310 ( 420).

When the deployment actuator 420 is driven, the gripping jaw 410 is reciprocated in the front and rear directions to grasp the gold foil and deploy it to the upper surface of the discharge unit 300.

On the other hand, when the gold foil is cut by the cutting part 200, the unfolding part 400 works in conjunction with the cutting part 200 to form an accurate cut surface to impart tension to the gold foil.

As shown in Figure 9, the deployment unit 400 operates in connection with this when the first pressing member 220 or the second pressing member 230 presses the gold foil, and pulls the gold foil backward to tension the tension section of the gold foil (S1) ). A portion of the gold foil is pressed by the first pressing member 220 or the second pressing member 230 and is pulled backward by the deployment unit 400 in this state, so that the first pressing plate 221 or the second pressing plate 231 Between the gripping jaw 410 is a tension section (S1) is formed.

The above-described first pressurized actuator, second pressurized actuator 232, deployment actuator 420, etc. may utilize known reciprocating power generating means such as oil, pneumatic cylinders, LM guides, and the like.

Hereinafter, the operation of the gold foil cutting device will be described with reference to the accompanying drawings. In this operation, the process of cutting the gold foil using a gold foil cutting device will be described as an example.

First, a plurality of gold foils are laminated in the supply unit 100 and discharged to the seating plate 210 of the cutting unit 200. At this time, the gold foil is discharged to the front portion of the seating plate 210 so that the gripping jaw 410 can grip one end of the gold foil.

Next, the gripping jaw 410 moves along the movement passage 310 to the tip receiving portions 212 and 221b, and then grips both sides of the gold foil. Then, as shown in FIG. 8, while the gripping jaw 410 is returned to the original position, the gold foil is developed on the upper surface of the discharge unit 300. Until the gold foil is cut, the gripping jaw 410 maintains the gripping state of the gold foil.

Next, as illustrated in FIG. 9, the first pressing member 220 and the second pressing member 230 are sequentially operated such that the first pressing plate 221 and the first pressing plate 221 are attached to the seating plate 210. A part of the seated gold foil is pressed. At this time, a tension section S1 is generated between the first pressure plate 221 or the second pressure plate 231 and the gripping jaw 410.

When the cutting of the gold foil is completed by the cutting member 240, the gripping jaw 410 releases the gripping state of the held gold foil, and the cut gold foil is placed on the upper surface of the discharge unit 300.

The user merges the gold foil seated on the upper surface of the discharge unit 300 together with the base paper BP and puts it into a separately provided packaging unit.

This process is repeatedly performed for repeated cutting of the gold foil. At this time, as shown in FIG. 10, when the gold foil is cut, the first pressing member 220 releases the pressing state of the gold foil and the second pressing member ( 230), even if the gold foil is cut, the first pressing member 220 and the second pressing member 230 are individually driven while having a time difference to maintain the pressurized state of the gold foil until immediately before the deployment portion 400 grips one end of the gold foil. do.

That is, the first pressing member 220 when the gold foil is cut by the cutting member 240 immediately releases the pressing state of the gold foil seated on the seating plate 210, and the second pressing member 230 is held ( 410) to maintain the pressurized state of the gold foil seated on the seating plate 210 until just before gripping one end of the gold foil for the deployment of the gold foil, it is possible to continuously maintain the lamination state of the gold foil.

As a result, it is possible to maintain the correct alignment of the sheet of gold foil in the entire process of cutting the gold foil.

The embodiments of the present invention described above are merely exemplary, and those skilled in the art to which the present invention pertains will appreciate that various modifications and other equivalent embodiments are possible. Therefore, it will be understood that the present invention is not limited to the forms mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
