[0003]
[Problems to be solved by the invention]
In the method of cutting by applying the conventional ruler, the ruler moves at the time of cutting and often makes a mistake in the cut. Especially, in the case of a film having a long length, the ruler cannot be pressed on average, so the film The problem arises that the four sides cannot be cut accurately, and the cutting surface (thickness 0.1 to 0.5 mm) is rough with a general cutter, and the four sides of the film cannot be skillfully adhered (burr Was a problem. Furthermore, conventionally, when a film is cut using a cutter, a urethane or rubber mat is laid on the lower side of the film, and the film is placed thereon to cut the film. There is a problem that it becomes impossible to cut skillfully, and there is a problem that the cutting edge of the cutter is severely damaged on the mat, and the cutting edge is damaged during cutting, resulting in poor sharpness.
[0004]

[0012]
As the elevating means 15, one having a configuration as shown in FIG. 5 is used. That is, on the outer surface of the upper plate 5 of each side panel 9, the mounting board 22 having a guide tube 21 that guides the shaft rod 20 through the shaft rod 20 and moves the shaft rod 20 up and down is fixed. A lever 24 is pivotably supported on a support plate 23 projecting from 22 and the upper end portion of the shaft rod 20 is pivotally supported on the lower end portion of the lever 24.
[0013]
Then, a fixing member 25 for connecting and fixing the lower end portion of the shaft rod 20 of the lever 24 on the horizontal bottom surface 18b of the both end portions of the guide protrusion 19 projecting on the film holding substrate 16 is provided. The outer side protrudes outward from each side panel 9 and is fixed.
[0014]
As shown in FIG. 5, each fixing member 25 for connecting and fixing the lower end portion of the shaft rod 20 includes each guide rib 19 on the inner side of the bottom plate 27 of the fixed substrate 26 having a concave cross section. In order to be placed and fixed on the horizontal bottom surface 18b of the guide plate 18, a notch portion 28 having the same width as that between the sliding contact surfaces 18a is provided, and a strip 27a divided by the notch portion 28 is provided. Is formed. Then, the inner portions of the respective fixing members 25 are inserted between the respective sliding contact surfaces 18a through the notches 28, and the both strips 27a are respectively placed on the guide protrusions 19 and screwed. Further, the lower end portion of the shaft rod 20 of each lever 24 is connected and fixed to the bottom plate 27 of the fixed substrate 26 that protrudes outward from each side panel 9. Accordingly, by operating the lever 24 to move the shaft rod 20 up and down, the film pressing member 3 moves up and down and is fixed at the respective vertical positions.
[0015]
The lifting / lowering means 15 having the above-described configuration is attached to each side panel 9, and is fixed to the fixing member 25 fixed to both side ends of the guide protrusions 19 protruding on the film pressing substrate 16. Since the lower end of the flange 20 is connected and fixed, when the film pressing member 3 is pushed down or pushed up by the lifting / lowering means 15, it is necessary to operate the lifting / lowering means 15 on both sides simultaneously.
[0016]
Further, by holding the level of the film pressing member 3 at one end and the other side end of the upright piece 18 d constituting the film pressing member 3, A horizontality adjusting means 29 for adjusting the horizontality for pressing the film 1 with an equal force and fixing the film 1 so as not to move is fixed via attachment members 30 and 31. Each of the mounting members 30 and 31 has a different structure because the method of attaching the horizontality adjusting means 29 is different on one side and the other side.
[0017]
The state of the film pressing member 3 when the leveling adjustment means 29 is not present will be described. When the film pressing member 3 is pressed down by the lifting / lowering means 15 on both sides and is pressed onto the film 1 on the film anti-slip plate 14, both ends of the film pressing member 3 are strongly attached to the film 1 by the pressing force of the lifting / lowering means 15. The film is pressed and the vicinity of the center of the film pressing member 3 is lifted. Alternatively, if the pressing force of the lifting / lowering means 15 is weak, the film presser member 3 sinks near the center of the film presser member 3 due to the weight of the film presser member 3 and the both ends of the film presser member 3 are lifted. When the vicinity of the center of the film pressing member 3 is lifted or both ends are lifted, the film pressing member 3 does not receive an equal force, so that the film 1 does not press the film pressing member 3 at that portion. As a result, the film 1 moves and there is a possibility that the film 1 cannot be accurately cut into a straight line.
[0018]
In the present invention, as described above, in order to prevent the film pressing member 3 from being moved near the center portion or both end portions of the film pressing member 3 and moving the film 1 in that portion, the horizontal direction of the film pressing member 3 is prevented. When the film holding member 3 is pressure-bonded onto the film 1 on the film anti-slip plate 14, the film 1 is pressed with an equal force so that the film 1 does not move. The adjusting means 29 is attached to the upper part of the film pressing member 3 with a gap from the film pressing member 3.
[0019]
The horizontality adjusting means 29 is mounted on the upright pieces 18d of the guide plates 18 constituting the guide ridges 19 with an interval 29a from the upright pieces 18d. The horizontality adjusting means 29 fixes the one end of the strip-shaped steel plate 32, which is substantially the same length as the film pressing substrate 16 and is thin, to the mounting member 30 on one side with screws or the like, The other end of the strip steel plate 32 is fixed to the other mounting member 31 so that the tensile force of the strip steel plate 32 can be adjusted.
[0020]
That is, as shown in FIG. 3, the mounting member 30 on one side constitutes the horizontality adjusting means 29 with a space on the upright pieces 18d of the guide plates 18 constituting the guide protrusions 19. The holding plates 33a and 33b are extended and fixed above the standing pieces 18d on the outer wall surface of the one end portion of the upright pieces 18d so that one end portions of the strip-shaped steel plates 32 can be fixed, and One end of the belt-shaped steel plate 32 is inserted into the gap 34 between the sandwiching plates 33a and 33b, and fixed with screws or the like.
[0021]
As shown in FIGS. 4 and 5, the other side mounting member 31 has an interval on each standing piece 18 d of each guide plate 18 that constitutes the guide protrusion 19, and adjusts the horizontality. The other end of the strip-shaped steel plate 32 constituting the means 29 is attached to the upright piece 18d so that its tensile force can be adjusted. That is, on the outer wall surface at the other end of each upright piece 18d, the sliding contact plates 35a and 35b are extended and fixed upward from the upright piece 18d, and a gap 36 is formed between the sliding contact plates 35a and 35b. The cut-out portion 37 is formed by cutting out the outer side of the upper portion of the sliding contact plate 35a on the front side, and the outer side of the upper portion of the sliding contact plate 35b on the back side is perpendicular to the cut-out portion 37 direction. A bent piece 38 is provided to be bent.
[0022]
And while extending the extension plate 39 to the other end part side of the said strip | belt-shaped steel plate 32, the other end part side of this extension plate 39 is bent at right angle to the front side, and the bending piece 40 is further formed, The extension plate 39 is inserted into the gap 36, and the adjustment bolt 41 is screwed between the bent piece 38 of the sliding contact plate 35 b on the back side and the bent piece 40 of the extension plate 39. The other end side of the film is connected and fixed to the attachment member 31 on the other side, and the adjustment bolt 41 is tightened or loosened to adjust the tensile force of the strip steel plate 32 to thereby adjust the level of the film pressing member 3. It is formed so that it can be adjusted.
[0023]
That is, the film 1 is laid over the film mounting plate 12a, the film anti-slip plate 14 and the film mounting plate 12b, or between the film mounting plates 12a and 12b and the film anti-slip plate 14. When the film 1 is press-contacted between the film pressing member 3 and the film anti-slip plate 14, as shown in an exaggerated manner in FIG. 6, the central portion of the film pressing member 3 is lowered by its own weight, When both side ends of the film pressing member 3 are lifted, when the adjusting bolt 41 is tightened, the tensile force of the belt-shaped steel plate 32 is increased, and the fact that the tensile force is increased acts on the film pressing member 3, Both side ends of the film presser member 3 are lowered to be in a horizontal state, and a force is uniformly applied to the entire film presser member 3. Film 1 with a uniform force by 3, is crimped onto the film slip prevention plate 14.
[0024]
The leveling adjustment means 29 is preferably adjusted before the film pressing member 3 is lowered and pressure-bonded onto the film 1 via the lifting / lowering means 15.
[0025]
Further, the cutter member 4 inserts the cutting edge 42a of the rotary cutter 42 into the gap 13 from above the film 1 after the film 1 fixed without moving between the film pressing member 3 and the film anti-slip plate 14, The rotary cutter 42 is rotated along the gap 13 for cutting.
[0026]
The cutter member 4 is rotatably supported on one side surface of the tip portion of the cutter holder 43 so that the blade edge 42a of the rotary cutter 42 is partially exposed from the cutter holder 43. On the inner surface of the cutter 42, when the rotary cutter 42 is not used, the blade 42 a protrudes outward from the blade edge 42 a to protect the blade edge 42 a, and for the safety of the operator. The tip of the operation piece 46 is inserted into the recess 45 of the cutter holder 43 so that the disk-shaped protective plate 44 having a diameter larger than that of the rotary cutter 42 that exposes the cutting edge 42a of the rotary cutter 42 is moved to It is fixed to.
[0027]
That is, when the rotary cutter 42 is not used, the operation piece 46 is pressed downward, the tip portion of the protection plate 44 protrudes from the blade edge 42a of the rotary cutter 42, and the blade edge 42a of the rotary cutter 42 is exposed to the outside. I try not to. Conversely, when the rotary cutter 42 is used, the operation piece 46 is moved upward so that the blade edge 42a of the rotary cutter 42 can be exposed.
[0028]
Further, on the rotary cutter 42 side of the cutter holder 43, the rotary cutter 42 is brought into sliding contact with the sliding contact surface 18 a of each guide plate 18 constituting the guide protrusion 19 projecting on the film pressing plate 16. A guide member 47 that rotates and moves is fixed together. The guide member 47 is formed so as to be placed on the crotch from the upper part of the guide protrusion 19 so as to be able to slide on the sliding contact surface 18a.
[0029]
That is, the guide member 47 is provided with two attachment pieces that are suspended from the lower portion of the fixed piece 48 fixed to the cutter holder 43 with a gap that can be crotched by the guide protrusion 19. On the lower surface of 49, the sliding contact surface 50 slidably contacting the outer surface of each sliding contact surface 18a of each guide plate 18 constituting the guide protrusion 19, and the sliding bottom surface 51 sliding on the horizontal bottom surface 18b are slid. A sliding contact plate 52 provided on the lower surface of the contact surface 50 is formed to project. It is recommended that the slidable contact plate 52 be formed of a synthetic resin plate having a small friction coefficient, so that the slidable contact plate 52 can smoothly move along each slidable contact surface 18a and the horizontal bottom surface 18b. It can be done. In the figure, reference numeral 53 denotes a protrusion to which a finger is applied when the operation piece 46 is moved up and down, 54 is a guide hole of the mounting bolt 55 when the operation piece 46 is moved up and down, and 56 is a protrusion formed in the fixed piece 48. 53 operation windows.
[0030]
The cutting edge 42a of the rotary cutter 42 of the cutter member 4 is inserted from above the film 1 into the gap 13 between the film mounting plates 12a and 12b and the film slip prevention plate 14, and the rotary cutter 42 is rotated to rotate the film 1. Although it cuts, it is necessary to adjust beforehand so that the clearance 53 of about 1 mm may be produced at least between the blade edge 42a of the rotary cutter 42 and the base plate 10. Therefore, the film mounting plates 12a and 12b and the film anti-slip plate 14 in the embodiment of the present invention have the same plate thickness of about 3 mm, and by setting each plate thickness to about 3 mm, A gap 57 of about 1 mm can be easily formed between the blade edge 42 a of the rotary cutter 42 and the base plate 10. By forming the gap 57 of about 1 mm, the cutting edge 42a of the rotary cutter 42 contacts only the film 1 and does not contact the base plate 10 at all, so there is no possibility of damaging the cutting edge 42a. The cut surface can be cut vertically and flatly. Further, since a mat is not used as in the prior art, the film can be cut easily and smoothly.
[0031]
When one side of the film 1 is cut by the cutter member 4, the lever 24 of the lifting / lowering means 15 is pushed up to move the shaft rod 20 upward, the film pressing member 3 is lifted, and then the other film 1 is cut. The position is adjusted so that the sides can be cut, and the above operation is repeated to cut each side.
[0032]
【The invention's effect】
Since the present invention is as described above, the entire cut portion of the film placed on the film placing table is uniformly pressed by the film pressing member with an equal force, so that there is a gap between the film pressing member and the film. Is fixed without moving, and after that, the cutting edge of the rotary cutter of the cutter member is inserted into the gap between the film mounting plate and the film anti-slip plate on the film mounting table, and the guide member is inserted into the film. By sliding along the guide plate constituting the pressing member, a gap is formed between the blade edge of the rotary cutter and the film mounting table, so that the blade edge of the rotary cutter is not damaged by the film mounting table, The cut surface of the film can be cut vertically and flatly, and the occurrence of burrs can be prevented. In addition, since it is not necessary to lay a mat under the film as in the prior art, the film can be easily cut without requiring skill.
