Description

Cutting machine and paper cutting machine for paper cloth {Autocutting machine for a sort of padding}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a paper cutting machine and automatic cutting machine for cutting tough or soft materials such as papers, fabrics, nonwovens, and paddings, or cutting dotted lines.

As a kind of paper cutting machine, there is a "non-woven fabric cutting device" of Patent Registration No. 152075, which consists of a plurality of roller sets, a folding assembly, and a circular knife, and is used to manufacture a non-woven fabric for surgical operation or treatment in a medical center. When the roller set transfers the rectangular nonwoven fabric, the folding assembly is folded in two layers, and the circular knife rotates to form a cut of a predetermined standard. The structure and use of the papermaking machine differ from that of the present invention. Therefore, detailed description thereof will be omitted.

And, the prior art of the present invention, there is a conventionally used cutting machine as shown in Figure 6, which is a roll support (6 ') for mounting a nonwoven fabric roll 71 wound around the nonwoven fabric (7) and the like; And a pair of press rollers 31 and 32 spaced apart from each other by a predetermined distance from the roll support 6 'and installed along the garter 49 at the rear of the press rollers 31 and 32. Rotating blade 41 which is transversely while moving, presser device 47 'which presses the nonwoven fabric 7 while advancing to the cylinder 470 from directly above the garter 49, and the rotary blade 41 reciprocally transverses. It consists of a power train that rotates while being rotated.

Then, the conventional invention configured as described above is mounted on the roll-shaped nonwoven fabric roll 71 wound on the first roll support (6 ') and unwinding one end of the nonwoven fabric (7) a pair of blotting rolls (31, 32) After inserting in between, the power transmission device is operated to transfer the nonwoven fabric 7 and the like by a predetermined distance. When the prescribed distance is conveyed, the holding paper rolls 31 and 32 are stopped, and the cylinder 470 is operated to make the nonwoven fabric by the paper holding device 47 '. While pressing (7), the rotary blade 21 is operated to cut the nonwoven fabric 7 to a predetermined length. At this time, if the cylinder 310 is attached to the upper side of the upper side of the upper side of the upper side of the upper side of the pressing paper rolls 31 and 32 so that the upper side of the pressing paper roll 31 is controlled upward and downward, the holding papers 31 and 32 are made of nonwoven fabric 7. When cutting while giving a feed force to the upper press roll 31 to be in close contact with the lower press roll 32, the nonwoven fabric 7 can be pressed, so that the cutting of the nonwoven fabric 7 can be easily and less error. have. In addition, by adding a control system for operating the paper holding device 470 and the rotary blade 41 after the paper holding rolls (31, 32) by a predetermined number of revolutions, the operator inputs the altar length automatically, and the nonwoven fabric of the predetermined length ( Some automated shredders are also currently in use to allow 7) to be continually altared.

However, the above-described conventional invention has a lot of work even though it is an automated cutting machine, which is operated after inserting the first nonwoven fabric 7 and the like between the blotting rolls 31 and 32 to operate the nonwoven fabric 7 and the like. This is because it is necessary to continuously take the lamination from the rear of the altar and stack it. Since the nonwoven fabric 7 such as cotton has a large sewn section, the altar can be secured or held. For this purpose, the holding papers 31 and 32 are stopped and the paper Since cutting the rotary blade 41 by rotating after cutting so that the cutting time is long during the cutting of a wide material is inefficient, and to increase the cutting efficiency, the rotary blade 41 should be large, although most of the garter Even if it is stored inside the lower surface (49) of the rotary blade 41 protrudes upwards partly threaten the safety of the worker, in particular the material cut to a predetermined length to the consumer For example, if the material is a packaging pattern, this type of consumer is usually a mass consumer and is packed as compressed as possible for the convenience of transportation of the stacked material. Separation is difficult due to the adhesion of the liver and if the separation is forcibly separated by the thicker or thinner than the thickness had at the time of the first laminated there was a problem that use is inconvenient.

The present invention was developed to solve all of the above-mentioned problems with careful observation and research, not only to enable precise cutting of each device, but also to cut the dotted line (part of the cutting line is not cut, so the materials are connected to each other. The whole device can reduce labor because it does not require manpower until the altar is completed.It also improves work efficiency by minimizing cutting time and ensures the safety of the operator. In addition, it is completed to be able to cut the material accurately in the width direction.

Hereinafter, the present invention will be described in detail with reference to the drawings.

It is more preferable if it is characterized by being made.

Unexplained reference numeral 11 is a retracting roll which is installed at the tip of the base 1 as a rotating material so that the material 7 enters each device without resistance, but even if omitted, it does not cause any trouble to the whole function.

As described above, the cutting device 2, the cutting device 4, etc. can be traded separately with a function that is sufficiently independent even in the configuration state, but for convenience of understanding, In the present invention made as described above, a process of performing altar work by using the overall apparatus schematically shown in FIG. 3 will be described in general, and each component will be described in detail.

The automated whole mill is first known as roll support 6 '; It is more preferable if it is replaced by the roll holder 6 of the present invention, and support the raw material roll 71, unwind one end and put it on the side of the cutting device (2) and operate the machine (7) roll support (6) ') To be cut to a predetermined width set by the rotary blade 21 of the cutting device (2), the rotary blade 21 is the upper and lower materials so the rotary blade 21 every predetermined time at the time of cutting As it rises, a dotted line cutting is also possible, and when the feed force from the paper holding device 3 is transferred to the transverse device 4, the transverse device 4 cuts in the width direction of the raw material 7, and the transverse device (4) also a plurality of rotary blades (41) are transported in interlocking, it is possible to cut the broken line, since the broken line is cut so that the material (7) is rolled on the roll mounting base (6) through the feeder (5) continuously after the cutting And the altar is completed, if the altar in the traverse device 4 is broken If it is not a complete cut, the material 7 is cut into a rectangle and descends on the belt 51 of the conveying device 5, so that a separate stock device must be installed at the bottom of the belt 51 to lift the operator's labor. Can be reduced.

One embodiment of the present invention, the truncation device (2) exhibits its function while operating as follows. In this case, the receiving frame (23) surrounds the device and protects the device while supporting each operation unit to operate properly. It is a frame, and a plurality of cutting devices are accommodated in a plurality of sets of rotary blades 21, in which the devices for cutting sidelines are made to fall up and down by a cylinder 22, and they are fixed at any position desired by the operator. For example, for example, a hexagonal frame is formed of metal cubes to form a storage frame 23, and one or more shafts are installed in the storage frame 23 in the horizontal direction to connect the boss to the cylinder 22. By moving the shaft by the cylinder 22 (many is installed, but only one will be described below) will be left and right freely, at this time, Since the rotary blade 21 is attached to the tip of the rod, the cutting width of the raw material 7 is determined according to which position the cylinder is positioned on the left and right sides. In this case, the cutting edge of the rotary blade 21 is kept constant during the operation. A slide panel 25 with slits is mounted on the front of the frame 23, and the handle 24 attached to the cylinder 22 is exposed to the front through the slits of the slide panel 25. That is, the handle 24 is positioned at a predetermined position of the connecting rod 25 (which has a metal ruler attached thereto so that the movement of the handle can be confirmed numerically), and the handle 24 is turned (clockwise). The handle 24 is approached toward the slide panel 24 so that a stopper made of rubber or plastic is pressed between the boss portion of the handle 24 and the slide panel 25 and fixed at the position. (22) is fixed and the rotary blade (21) It is fixed. Then, when the rotary blade 21 is axially supported by the piston rod 221 of the cylinder 22 and the rotational force is transmitted, the rod 221 of the cylinder 22 is elongated (downward in the drawing) while rotating, thereby rotating the blade 21. When the material 7 is in contact with the raw material 7, the raw material is cut, and the drum 12 is provided on the upper surface of the base 1 directly below the shaft center of the rotary blade 21 to increase cutting efficiency. While the opposite material 7 can be supported, the drum 12 may be supported by a bearing so as to be manually rotated, but the circumferential speed is increased by a motor (not shown) installed in the base 1. It is more preferable if the motor is made to match the feed speed of 7) to prevent slippage of the material 7 so as to be suitable for cutting.

The transverse device 4, which is another configuration of the present invention, functions as follows.

The transverse device 4 has a garter 49 which is recessed a predetermined depth perpendicular to the direction of travel of the workpiece 7 on the upper surface of the base 1 as a frame for supporting it, which penetrates the workpiece 7 during operation. The rotary blades (41, 41, ...) are to be inserted so that the material can be easily cut. In addition, between the ball star (45, 45) is inserted into both sides of the housing frame 42, and is moved up and down by the cylinder (46, 46) installed in the lower portion, the connection between the ball star (45, 45) The cylinders 46 and 46 respectively installed on both sides of the receiving frame 42 are configured to connect the ball rods 45 and 45 on the box and the connecting rods 44 up and down, wherein The cylinders 46 and 46 are also controlled to be stretched / contracted to the same length}, a bearing bar 43 left and right retracted by a piston (not shown) mounted to the ball star 45, and the bearing bar 43 It is composed of a plurality of rotary blades (41, 41, ...) that the shaft is supported, each ball star 45 to move up and down, the piston mounted to the ball star 45 is left and right the bearing bar (43) Since the rotary blades 41, 41,... Which are rotatably supported by the bearing bar 43 during cutting, are simultaneously transported and cut. Therefore, the plurality of rotary blades 41, 41, ... can be controlled at the same time while being transported simultaneously. Of course, at this time it is also possible to cut the dashed line so that a portion of the raw material (7) is connected without being cut by making the transfer distance of the axis bar shorter than the interaxial distance between the rotary blades (41, 41). In addition, the material 7 is composed of a pusher 47 which is integrally installed before and after the rotary blades 41, 41,... Through the springs 48 at both sides of the housing frame 42. When the rotary blade 41 is lowered in the state passing through, the tacker 47 is also lowered together, although the lower surface of the tacker is vertically inserted into the lower surface of the storage frame 42 even though the rotary blade 41 is at the same height as the rotary blade 41. Since the rotary blade 41 is accommodated in the garter 49 by the garter 49, the rotary blade 41 does not interfere with the moment when the tack 47 is in contact with the periphery of the garter 49 of the base 1. No, since the bearing bar 43 is further lowered, the spring 48 is compressed, and the shaft inserted into the paper holder 47 enters the paper holder 47, so the paper holder 47 does not come down anymore. At this time, the material 7 is firmly supported by the holding force of the spring 48. In this state, when the rotary bar 41 rotates left or right while the rotary blade 41 rotates with power transmitted from the outside, a predetermined cut (complete cut or dotted cut) is made.

The function of each part of the automatic cutting machine which consists of the whole structure which is another structure of this invention is concretely described as follows.

The roll support 6 ′ of the present invention is a known one configured to support a material roll 71 wound on a material 7 in roll form, for example, a roll bar that is a circular rod fitted in the center of the material roll 71. Both ends of (61) are loosely inserted (more preferably, if a bearing is placed) and the material roll 71 is held in the air so that the material 7 can be released without resistance from the material roll 71. It is more preferable to replace it with the roll holder 6 of the present invention. In addition, the cutting device 2 of the present invention is the length of the material (7) by a plurality of rotary blades 21 is controlled up and down while the material (7) is introduced and spaced apart from the roll support (6 ') a predetermined distance It is provided so as to cut in the direction, and then the paper holding device (3) to be mounted is composed of one or more pairs of upper and lower pressure paper rolls 31, 32, 31, 32, ... that presses the material therebetween and imparts a feed force ( In FIG. 4, the material 7 is firmly gripped and conveyed by the pressing rolls 31 and 32, which is too flexible such as a nonwoven fabric or a cotton, and thus is not easy to cut. Altar can be done easily and accurately. However, the holding device 3 is not only a secondary function of imparting a conveying force, but also firmly grips for the transversal of the traverse device 4 described later rather than the traverse device 2 as a main function, which is the traverse device. Since (2) cuts the raw material 7 conveyed in the longitudinal direction in the longitudinal direction, the tension applied to the raw material 7 naturally helps the cutting of the raw material, but the transverse device 4 moves in the advancing direction of the raw material 7. Since cutting in the direction perpendicular to the raw material (7) is transported during transversal rather than hinders the altar, during the transverse the paper holding rolls (31, 32) of the paper holding device (3) by stopping the rotation It is to be firmly supported. To this end, in the present invention, two or more pairs of press paper rolls 31 and 32 are to be disposed. For example, when two pairs of paper rolls 31 and 32 are slightly spaced apart, the material 7 of a predetermined area is pressed and supported. You can be sure. In addition, the transverse cutting device 4 is installed so that the plurality of rotary blades 41 are interlocked and rotated in the width direction of the material 7 to be conveyed. Therefore, even if you want to make a complete cutting, if you transfer only to the position of the rotary blade 41 located next to it, the transversal is completed, and the working time can be drastically reduced. Made easy In addition, since the conveying device 5 is formed by winding the belt 51 between the support roll 53 and the pressure-rolling roll 54 so as to transport the cut material 7, the cut material 7 moves the belt 51. Ride smoothly to the next device, and at this time, the support roll 53 is a manual roll that rotates without power, and the feed roll 54 is a motorized roll directly connected to the motor or connected to the chain or belt to more properly exhibit the function. It is possible to, but the reverse or even if both the rolls (53, 54) are driven at the same circumferential speed, there is no problem in the operation. In addition, the roll holders 6 are placed in a pair opposite each other, so that both ends of the roll bar 61 having the material 7 rolled up in a roll form are mounted with the up and down material along the guide slits 62, so that the roll holder 61 is mounted on the first roll bar 61. If only slightly wound around the tip of the material (7) it is then automatically rolled into a roll, which is the roll bar 61 is located in the guide sleet 62, which is the lower portion of the holder (6), but the material (7) When the thickness of the rolled material (7) is thick while winding, the roll bar (61) is smoothly climbed on the guide slits (62), and the winding roll (65) is rotated by electric power at the rear of the roll holder (6). (7) is wound around the roll bar 61 by the interaction between the belt 51 and the winding roll 65 is rolled into a roll without difficulty. In particular, the base 1 has the truncation device 2, the paper holding device 3, the transverse device 4, and the transfer device 5 sequentially attached to transfer power to the devices 2, 3, 4, and 5, respectively. The motor and chain are installed so that the distance between each device can be made straight and it is convenient.

In a further configuration of the present invention, the paper holding device 3 has a more convenient and improved function. For this purpose, the paper holding device 3 of the plurality of paper holding devices 3 includes a pair of posts 315 and 315; Posts may be installed separately, but using the storage frame (23, 42) of the truncation device (2) and the transverse device 4, the cylinders (310, 310) attached to each of the separate posts}, The shafts 311 and 312 attached to the rods of the respective cylinders 310, the shafts 311 connecting the two shaft guides 312 and 312 and having pinions 314 and 314 formed at both ends thereof, and Each of the pinions 314 and 314 meshed with the racks 313 and 313 attached to the respective posts 315 and the upper press rolls 31 connected to the shaft guides 312 and 312 and rotated, respectively. Since the upper pressing roll 31 is vertically moved up and down by the shaft guides 312 and 312 which are vertically advanced by receiving the retraction force of the cylinders 310 and 310, the shaft guides 312 and 312 are the shafts 311. And the shaft 311 is vertically up and down by the racks 313 and 313 and pinions 314 and 314 attached to both sides, so that the upper press roll 31 is always the same at both ends. Even if the length of the rolls (31, 32) is long enough to maintain the same distance from the lower squeezing rolls 32 to be described later, even if the material (7) having a variety of thickness is adapted to this constant transfer Force and holding power. In addition, the lower pressing roll 32 is axially supported on the base 1 to be rotated and fixed to a predetermined height, and either a manual roll or a rolling roll may be used, but a rolling roll and the upper pressing roll 31 are used. It should be rotated in the same manner as there is no slip (Slip) is preferable.

In a further additional configuration of the present invention, the conveying device 5 is to have a more convenient and improved function, for this purpose, the conveying device 5 is between the rotating support roll 53 and the conveying roll 54 Is enclosed with a belt 51, and a plurality of plate-shaped belt bars 52 are attached to the outer circumference of the belt 51, and the belt bars 52 are plate-shaped, for example, plate wood, with a predetermined width. When the paste is configured, the material 7 can be effectively transported without slip, and the material 7 can be rolled well together with the winding roll 65 to be described later, and the roll holder 6 is a guide slitting ( 62, the hinge 63 is attached to the middle of the roll holder 6 divided into two, and the attachment hole 64 is formed at the upper end thereof so that the material 7 is completely wound and rolled. When taking out from the holder (6), remove the white paper (63) of the roll holder (6) Come open, while the mounting opening (64) are separated so one end of a roll cradle (6) is open the material roll 71 is required lift height of the rollbar 61 wound around it is convenient to be able to take out. At this time, the attachment hole may use a combination of the ferrous metal and the magnet, or may be formed to face the concave concave portion like a snap button, the force applied to the roll bar 61 is a problem even if the coupling force is small because most of the force in the vertical direction There is no.

The present invention not only allows the precision cutting of each device, but also allows the cutting of the dotted line (a part of the cutting line is not cut so that the materials are connected to each other), and the whole device is operated until the altar is completed. It does not require manpower, so it can reduce labor, minimize cutting time, improve work efficiency, ensure the safety of the workers as much as possible, and also make it possible to accurately cut the material in the width direction.
