Description

A continuous cutting apparatus for paper

The present invention relates to a continuous cutting device for paper, and more particularly, to a continuous cutting device for paper that continuously cuts along the paper being conveyed.

      When we leave the laundry to the laundry, the cleaner sees the finished pants hang on a disposable hanger. The disposable hanger used by the laundry bends a long, thin wire into a triangle to The crosspiece is widely used.

      However, if you hang your pants on the rung of a disposable hanger made by bending a wire, the radius of the wire (this radius is often called "R") is small, so that it is bent at a right angle to the wire forming the rung. As a result, households often insert round newspapers into hangers on their hangers and hang their pants on them to prevent them from breaking.

     In laundry shops, etc., when using a wire hanger, so-called anti-wrinkle pads are used to prevent breaks in pants hanging on the rungs of the hanger. Wrinkle protector is a paper product that is very long in length compared to the width by rolling up thick paper such as cardboard or card board so as to withstand the weight of the pants hanging on it. In particular, the anti-wrinkles have both ends fitted to the other two hypotenuses of the triangle to surround the crosspiece. Because of this, both ends of the anti-wrinkle band are formed with cracks.

     In order to manufacture the anti-wrinkle bar, first, the paper is cut long and then the cut paper is subjected to a U-shaped or semi-circular shape.

      Cardboard or cardboard, which is the material for wrinkle protection, is supplied in the form of rolls in paper mills, and the paper handling shops unwind it and cut and sell it to the desired size.

      A method of manufacturing a wrinkle protector using paper cut in the form of a plate is known from Patent Registration No. 10-613216. In Patent Registration No. 10-613216, a sheet of paper cut to a predetermined size and loaded is supplied to the cutter by automatic feeding in sheets, and the cutter firstly cuts the supplied paper in a lengthwise direction to have a constant width. .

      However, the method of Patent Registration No. 10-613216 uses a piece of paper cut in advance to a certain length so that the part cut off when forming the grooves at both ends cannot secure sufficient length to cover the crosspiece of the hanger. There is a disadvantage in that the loss is large, and the paper cut in the form of a plate is supplied in a single sheet, so that the cutting speed is slow.

      A device for cutting and unwinding paper rolls in roll form is known from Patent Registration No. 10-0364324. The apparatus of registration No. 10-0364324 is a primary cutting machine for cutting in the vertical direction with respect to the surface of the raw material by using the main roller and the auxiliary roller having a vertical cutting blade when the raw material wound into the feeder in the roll form horizontally, 1 When the raw material is cut in the vertical direction by the secondary cutting machine, the secondary cutting machine includes a primary roller having a horizontal cutting blade and a secondary roller for cutting in the horizontal direction to separate the raw materials into units.

      The device of registration No. 10-0364324 is the first cutting machine. When the raw material wound in the feeder enters horizontally, the raw material is cut in the width direction with respect to the surface of the raw material. The secondary cutting machine uses the primary cutting machine. When entering the cut state in the direction of the cut again in the longitudinal direction to separate the raw materials of the unit. This primary cutting machine is composed of a main roller and a secondary roller having a vertical cutting blade, the secondary cutting machine is composed of a main roller and a secondary roller having a horizontal cutting blade.

      By the way, in the apparatus of registration No. 10-0364324, the paper is cut first by the roller of the first cutting machine cutting in the width direction, the paper cut is not smoothly transferred to the wrinkle protector molding machine, the work speed is slowed in the next step There is this. In addition, when cutting the paper while the roller rotates, the circumference of the main roller of the primary cutting machine for cutting the wound paper in the width direction needs to be the length required by the wrinkle guard, so that the length of the wrinkle support is changed. At this time, there is a disadvantage that the size of the main roller should also be changed.

The second cutting tool 400 of the material is installed on the reciprocating mechanism 500. The reciprocating mechanism 500 reciprocates the second cutter mechanism between a first cutting position at which the first group of punching mechanisms perform a cutting operation, and a second cutting position at which the second group of punching mechanisms perform a cutting operation.

The structure of the reciprocating mechanism which reciprocates the 2nd cutting tool of a raw material is shown in FIG. Referring to FIG. 9, the reciprocating mechanism 500 includes guide rails 513 installed on the left and right sides of the frame 13, and a pair of guide blocks 515 mounted on each guide rail 513. And a horizontal support plate 501 for supporting the second cutting tool 400 for cutting the material placed on both of the guide blocks 515 in the width direction, and a vertical support member 503 standing on both sides of the horizontal support plate 501. ).

On the vertical support member 503 which is erected on both sides of the horizontal support plate 501, the lower mold 410 of the widthwise cutting cutter tool 400 of the material is placed thereon.

In front of the right and left sides of the horizontal support plate 501, a rod mounting member 507 for supporting the rod 509 to which the spring 511 can be inserted is provided. The rod 509 installed in each rod mounting member 507 further extends beyond the hole 515h formed in the rod support member 515 attached to the inside of the left and right frames 101. A spring 511 is fitted between the rod mounting member 507 and the rod supporting member 515. The cam follower 521 is attached below the horizontal support plate 501.

On the other hand, the motor support plate 561 is provided in the middle part of the frame 101, and the motor 531 is provided on the motor support plate 561. As shown in FIG. The rotary shaft 533 of the motor 531 extends upward, and the cam 523 is fitted to the rotary shaft 533 of the extended motor. The cam 523 has a cam surface B farthest from the cam surface A at the closest distance from the rotational axis 533 of the motor, and the cam follower 521 is farthest from the cam surface A at the closest distance from the rotation shaft 533 of the motor. It moves between cam surface B of distance.

As the cam follower 521 moves between the cam surface A at the closest distance from the rotational axis 533 of the motor and the cam surface B at the farthest distance, the horizontal support plate 501 also has a cam surface closest to the rotation axis 533 of the motor. Move between A and the farthest cam surface B. Until the motor rotates and the cam follower 521 passes the closest cam surface A from the rotational axis 533 of the cam 523 and contacts the cam surface B at the farthest distance, the horizontal support plate 501 is the same as the flow of material. Direction, the horizontal support plate 521 is formed until the cam follower 521 contacts the cam surface A at the closest distance past the cam surface B at the farthest distance from the rotational axis 533 of the motor of the cam 523. Move in the opposite direction to the flow.

At this time, the spring 511 is inserted between the rod mounting member 507 and the rod support member 515 is gradually compressed when the horizontal support plate 501 moves in the same direction as the flow of the material, cam cam 521 is most Maximum compression is achieved when the cam face B is reached at a distance. The elastic force of the spring 511 is a force that pushes the horizontal support plate 501 in the direction opposite to the flow of the material when it is restored. When the cam follower 521 passes the cam surface B of the longest distance, the elastic force of the spring causes the horizontal support plate 501 to move in the opposite direction to the conveying direction of the material until the cam follower 521 touches the cam surface A of the nearest distance. do. When the cam follower 521 passes the cam surface A of the closest distance, the cam follower 521 compresses the spring 511 again until it reaches the cam surface B of the longest distance.

When the cam follower 521 contacts the cam surface A of the closest distance from the rotation shaft 533 of the motor, it corresponds to the first cutting position, and the second cutting position when it contacts the cam surface B of the farthest distance. When the motor rotates and the cam 523 pushes the cam follower in the conveying direction of the material until it reaches the cam face B at the longest distance from the rotation axis of the cam, the guide block 515 attached to the lower side of the horizontal support plate 511 is also a guide rail. Along the conveying direction of the workpiece downstream. The raw material continuously exits from the upstream side to the downstream side while the motor is rotated and the cam 523 is pushed in the advancing direction of the raw material until the cam follower 521 reaches the cam surface B farthest from the rotation axis of the cam. When the cam follower 521 touches the cam surface B farthest from the rotation axis of the cam, air enters the air inlet 433 of the cylinder 431 to lower the piston (not shown) inside the cylinder. When the piston is lowered down, the cylinder rod cuts the material passing through the material progress passage 401 by pushing the punch attached below.

When the material is cut, air enters the air inlet 435 of the cylinder to raise the piston inside the cylinder and pull up the cylinder rod to lift the punch 439 up.

As the motor rotates as described above, the cam 523 follows the second cutting tool in the advancing direction of the material until the cam follower reaches the cam surface B farthest from the rotation axis of the cam, and continuously exits from the upstream side to the downstream side. Have the material cut. In addition, the second cutting tool is moved in the direction opposite to the traveling direction of the raw material until the cam 523 reaches the cam surface A at the closest distance from the rotational axis of the cam, and continuously exits from the upstream side to the downstream side. Have them cut the outgoing material.

Since the material continuously exiting from the upstream side to the downstream side is cut by the second cutting tool without stopping, it is possible to cut a large amount of material to a constant length in a short time, thereby reducing the production cost.
