Description

[Detailed Description of the Invention] Industrial Application Field This invention is for use in word processors, computers, and their peripheral equipment, and relates to a continuous paper edge cutting device that has a large number of feed holes on both side edges.

Conventional technology Conventionally, when converting continuous paper after printing into single sheets, the edges on both sides are cut at perforations perpendicular to the longitudinal direction immediately before cutting. I was going there.

Problems to be Solved by the Invention Based on the above, conventional border cutting of this type of paper has the following problems.

(1) When converting continuous paper after printing into single sheets, even if there is an automated device that separates paper at perforations perpendicular to the longitudinal direction, it is necessary to perform edge cutting operations on both side edge surfaces immediately before it. Since this was done manually, it took a lot of time and effort to convert continuous paper into single sheets, making it impossible to achieve rapid information processing.

(2) Also, on both sides of the device that separates the continuous paper after printing at perforations perpendicular to the longitudinal direction,
Some attempts have been made to automate edge cutting by attaching an edge cutting device, but because it is technically extremely difficult to rotate the upper and lower blades in contact with each other on the same line, continuous edge cutting cannot be achieved due to interruptions. Ta.

Means for Solving the Problems This invention solves the problems of the prior art described above, and instead of rotating the upper and lower blades in contact with each other on the same line, the two sides are made to face each other using a scissors method. To provide a continuous paper edge cutting device which can automatically perform complete continuous edge cutting while preventing occurrence of discontinuity by contacting and rotating the paper, and can smoothly and easily achieve rapid information processing. The feature of this invention is that the upper shaft, which has a paper presser attached to one end of the outer shaft, is rotatably inserted into the upper slide notch groove of the frame, which has a protrusion on one of the inner side surfaces. A movable lever that moves the upper shaft integrally in the vertical direction using the guide shaft at one base end as a fulcrum is fitted onto the outer shaft of the shaft, and a lever on the outer shaft is fitted into the lower shaft hole of the frame. A lower shaft with a pulley attached to one end is rotatably inserted through the shaft, and a gear and a main roller blade are fitted together on the shaft within the frame of this lower shaft,
Further, on the shaft within the frame of the upper shaft, a gear that meshes with the gear of the lower shaft and a slave roller blade that can be separated and come into contact with each other face-to-face while being supported by the main roller blade are separately fitted. be.

Function: When the edge cutting device with the above configuration is installed in the middle of both sides of a device that has a continuous paper separation mechanism to perform edge cutting operations, the lower shaft is rotated via a belt suspended between the drive source and the pulley. However, when the tip of the movable lever swings down using the guide shaft at the base end as a fulcrum, the upper shaft, which was previously located at the top of the slide notch groove, moves integrally with the movable lever into the notch groove. In order to descend to the bottom position, the gear installed on the shaft inside the frame of the upper shaft meshes with the gear on the lower shaft, and the upper shaft starts rotating in conjunction, and at the same time, the movable lever lowers, causing the slave roller blade to move. One side is released from the extrusion press contact made by the convex on the inner surface of the frame, and moves down in the axial direction due to the supporting force from the side, so the slave roller blade is moved down to the fixed position. By using the main roller blade and the scissors method, both sides come into contact with each other in a face-to-face manner.
Therefore, from the time when the edged continuous paper fed from the rear to the front reaches the frame position of the edge cutting device, it is brought into face-to-face contact using the scissors method described above.
The edge cutting operation of continuous paper can be performed stably and automatically in a state in which the occurrence of breaks is prevented and in a state in which the peripheral surface of the edge is pressed by the paper presser on the upper shaft side. In addition, when the edge cutting is completed as described above, move the movable lever that had been lowered until then.
On the other hand, when the guide shaft at the base end is used as a fulcrum to rise in a swinging manner, the gear on the upper shaft side that rises together with this lever interrupts the engagement with the gear on the lower shaft side, so at this point the upper shaft At the same time, the rotation disappears, and at the same time, the slave roller blade is again pressed by the protrusion from the side, and lifts up while releasing the face-to-face contact with the main roller blade due to the support bullet, thereby cutting edges on both sides. The device can then be readied again for a trimming operation.

Embodiments Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

Part of it is shown in Figures 1 and 2 (the left side when viewed from the upstream side of the left and right pair installed on both sides of the paper path)
As shown in the figure, this edge cutting device is constructed as follows. That is, the frame 1, which is the base of this edge cutting device, is formed into a vertically hollow box shape by bending a metal plate. The surface and a part of the rear vertical surface adjacent to this side are cut out to have a belt-like height and width as a paper running notch 6. A vertical slide notch groove 2 is provided in each intermediate band on both vertical surfaces of the upper side of the paper running notch 6 for vertical movement by inserting an upper shaft 3 (to be described later) therethrough. has been done. In addition, in the outer vertical surface of the frame 1 according to this aspect, on the vertical surface corresponding to the rear part of the slide notch groove 2 on this side, there is a guide groove (not shown) for a guide shaft 11 that becomes a fulcrum shaft of a movable lever 10 to be described later. ) is provided. Further, on the vertical surface on the opposite side, on the inner surface directly above the slide notch groove 2 on this side, there is a follower roller blade 21 to be described later.
is pushed out in the axial direction and pressed into contact with the main roller blade 18 directly below.
A convex element 4 is provided for separating from the base.
Furthermore, at the front position near the bottom of the frame 1, a part of the front side matches the guide piece 13 of the movable lever 10 during descent, and the main roller blade 18 at that point matches.
A chute 24 is provided for guiding the edge surface of the continuous paper E, which has been edge-trimmed by the roller blade 21 and the follower roller blade 21, downwardly. (See Fig. 1) Inside both notched grooves 2 of the frame 1 described above, there is an upper shaft 3 on each side of which a paper presser 7 made of a disc is attached to one end of the external shaft by screwing a key screw 8. It is rotatably inserted through a shaft-fitted bearing 9. A movable lever 10 shown below is attached to both bearings 9, which support the outer shaft portion of the support shaft 3 protruding to the outside of both sides of the frame 1, through a shaft hole 1 penetrating through the opposing surface.
It is pivotally fitted with two fittings so that it can swing. This movable lever 10 is formed as follows.
In other words, this movable lever 10 is constructed by bending a band-shaped plate into a substantially U-shape, screwing the guide shaft 11 inward into the protruding part of the base end located on the outer vertical surface side of the frame 1, Inside is chute 2 which will be described later.
A guide piece 13 that coincides with 4 is projected in a diagonally downward manner. In addition, when the tip of the guide shaft 11 is inserted into the guide groove (not shown) of the frame 1, the movable lever 10 has a movable angle B (approximately 15 degrees) on the tip side with the guide shaft 11 serving as a fulcrum. The upper shaft 3 is configured to be able to swing, and thereby the upper shaft 3 can also be moved up and down within the slide notch groove 2 integrally with the movable lever 10.

In the lower shaft hole 5 of the frame 1 described above, there is a lower shaft 14 having a pulley 15 mounted on one end of the external shaft with a key screw 8 screwed into it, and a bearing 1 fitted on each side thereof.
6, and is rotatably inserted therethrough. A gear 17 is mounted on one side of the inner shaft of the lower shaft 14.
In addition, on the other side, there is a main roller blade 18 with a cylindrical portion having a diameter that matches the running path height of continuous paper E, which will be described later.
Both are rotatably fitted to the lower shaft 14 with radial screws 19 inserted into the contact positions of both.

Similarly, on one side of the shaft within the frame of the upper shaft 3, a gear 20 of the same diameter that meshes with the gear 17 of the lower shaft 14 is connected to the upper shaft 3 with a radial screw 19 inserted therein. It is shaft-fitted so that it can rotate integrally. Further, on the other coaxial side, a follower roller blade 21 shown below is fitted so as to be movable in the axial direction. This follower roller blade 21 is formed as follows. In other words, when the upper shaft 3 descends, this follower roller blade 21
It has a diameter that allows face-to-face contact with the inner cutting surface of the main roller blade 18 located below the running path of the continuous paper E, and has an outer cutting surface on the inner cutting surface side of the main roller blade 18. Attach the mounting surface to the gear 20 above.
A push spring 2 disposed between and this follower roller blade 21
With a supporting force of 2, it is possible to detach using scissors method,
They are shaft-fitted so that their sides come into face-to-face contact with each other, thereby making it possible to trim the edges of the continuous paper E on each side, which will be described later.

In the follower roller blade 21 according to the above embodiment, when the movable lever 10 is in the upper position shown by the imaginary line in FIG. Since it is located at the inner vertical surface of the frame body 1, it is pushed out and pressed from the side by the protrusion 4 protruding from the inner vertical surface of the frame body 1, and moves toward the coaxial gear 20 by resisting the supporting force of the push spring 22. .
Therefore, when the movable lever 10 initially descends, the position of the cutting edge is axially distant from the lower main roller blade 18, so that both cutting edges are separated from each other until the subordinate roller blade 21 is completely lowered. It is constructed to eliminate any damage or injury due to contact in the radial direction. Furthermore, when the movable lever 10 is completely lowered, the outer surface of the follower roller blade 21 separates from the protrusion 4 and is released from the extrusion pressure contact that has been made up to that point. 21 is a push spring 22
Due to the supporting force of the roller, it moves in a direction away from the coaxial gear 20, so that when it is completely lowered, the upper slave roller blade 21 and the lower main roller blade 18,
It is constructed so that the edge cutting operation can be performed in a state where both sides are in face-to-face contact and there is no clearance, and two pieces of the same type according to this aspect are constituted as a set of edge cutting devices. Reference numeral 23 denotes an E-ring that prevents the bearings 9, 16 of the upper shaft 3 and lower shaft 14 and the movable lever 10 from falling off the shaft at each position.

When the edge cutting device with the above configuration is installed on both sides of the paper running path, the main parts of the device located on the left side of one of them when viewed from the upstream side of the running path are arranged in the second direction.
As shown in the figure, the arrangement of the main parts of the device, which is disposed on the other right side (not shown), is symmetrical from side to side with that of FIG. 2. In addition, the two upper and lower feed rollers 25 and 26 shown at the front position of the apparatus in FIG. In order to do
It is installed to convey the paper E to this separating device (not shown). Therefore, when edge cutting is performed by this edge cutting device, the paper E is pulled in the upstream direction.

When performing an edge cutting operation by installing a pair of edge cutting devices configured as described above at both sides of a machine (not shown) having a separating mechanism for continuous paper E,
First, before starting to feed the paper, adjust the width of either the left or right frame 1 of the above device to match the edge cutting position of the paper size, and then
Drive source (not shown) and lower shaft 1 common to the cutting device
Belt suspended between pulleys 15 of 4 (not shown)
While rotating the lower shaft 14 through The upper shaft 3, which had been held there, is lowered to the bottom position of the notched groove 2 together with the movable lever 10. Therefore, since the gear 20 mounted on the shaft within the frame of the upper shaft 3 meshes with the gear 17 of the lower shaft 14, the upper shaft 3 also starts to rotate continuously, and at the same time the movable lever 10 described above starts rotating. When descending, the bladed side surface of the follower roller blade 21 is released from the pressure contact in the inward direction by the protrusion 4 on the inner surface of the frame body 1, and the supporting force of the pressing spring 22 from the opposite side causes the shaft Since the slave roller blade 21 descends while moving in the direction, when the slave roller blade 21 descends to the fixed position, both rotate under the force supported by the main roller blade 18 of the lower shaft 14 and the scissor system. However, the sides come into contact with each other in a face-to-face manner. (See Fig. 2) Therefore, from the time when the edged continuous paper E that has been fed from the rear to the front side of the device reaches the paper running notch 6 of the frame 1,
This paper E is placed on a conveyor table (not shown) in a state in which the two roller blades 18 and 21 are brought into face-to-face contact using the scissors method described above to prevent the occurrence of breaks, and by a paper presser 7 (not shown) on the upper shaft 3 side. It is possible to stably and automatically trim the edges of continuous paper while the edge circumferential surface is pressed.

When the edge cutting of the continuous paper E is completed as described above, the movable lever 10, which had been lowered until then, is raised in a swinging manner using the guide shaft 11 at the base end as a fulcrum. The shaft 3 also rises, but at this time the gear 20 mounted on the shaft within the frame of the upper shaft 3 interrupts meshing with the gear 17 on the lower shaft 14 side, so at this point the rotation of the upper shaft 3 stops. It will disappear. At the same time, the follower roller blade 21 of the upper shaft 3 is again subjected to the extrusion pressure contact of the protrusion 4 on the frame body 1 side. Therefore, this slave roller blade 21
moves in the axial direction closer to the gear 20 while resisting the supporting force of the push spring 22, so at this point it rises while releasing the face-to-face contact with the main roller blade 18 on the lower shaft 14 side. As a result, the left and right edge cutting devices can recover their readiness for another edge cutting operation at their original positions on the paper travel path.

Effects of the invention In this invention, an upper shaft with a paper presser attached to one end of the outer shaft is rotatably inserted into the upper slide notch groove of the frame body, which has a convex portion on one side of the inner side. A movable lever is fitted onto the outer shaft of the frame to integrally move the upper shaft vertically using the guide shaft at one base end as a fulcrum, and one end of the outer shaft is fitted into the lower shaft hole of the frame. A lower shaft equipped with a pulley is rotatably inserted into the lower shaft, and a gear and a main roller blade are fitted together on the shaft inside the frame of the lower shaft, and a lower shaft is mounted on the shaft inside the frame of the upper shaft. It is characterized in that the gear that meshes with the gear on the shaft and the slave roller blade that can be detached from the main roller blade and come into face-to-face contact while being supported by the main roller blade are separately shaft-fitted. Therefore, when cutting the edges of continuous paper, instead of rotating the upper and lower blades in contact with each other on the same line, the edges of both sides are rotated in a scissors style, with the sides facing each other, thereby preventing the occurrence of breaks and cutting the edges completely. This method has the advantage that continuous edge cutting can be performed automatically, and rapid information processing can be achieved smoothly and easily.
