Abstract

PURPOSE:To separate continuous sheets with small force by rounding the edge part of a blade to be brought into contact with the continuous sheets. CONSTITUTION:A blade 16 is brought into contact with the scores of continuous forms to separate the continuous form as if tearing it off from the scored part. At this time, contact resistance between the blade 16 and the continuous form becomes less because of the roundness of the edge part 16a of the blade 16, so that the continuous form can be separated with small force. Moreover, as the edge part 16a of the blade 16 is not sharp, the continuous sheet is prevented from being separated from the part other than the scored part even if the blade 16 touches the part other than the scored part.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a continuous paper separating device for separating continuous paper such as tickets.

2. Description of the Related Art Conventionally, there has been a so-called continuous paper separating device that separates continuous paper at perforations using a blade. When such devices are classified from the viewpoint of paper separation method, they are roughly divided into one cutter type and burst type.

The single cutter type uses a cutter with a sharp edge as a blade to separate continuous paper by cutting it at perforations. Among these one-type cutters,
Depending on the cutting operation, there are two types of cutting methods: the rotary cutter, which cuts continuous paper by rotating the cutting edge, and the guillotine, which uses a pair of cutters to cut continuous paper in the same way as scissors.

On the other hand, the burst method uses a burster with a blunt edge as a blade, presses the continuous paper with the burster, and separates the continuous paper by tearing it at the perforations. That is, the principle is that by pressing the burster against the continuous paper, a pulling force is applied to the continuous paper in the left-right direction of the perforation, and the continuous paper is torn at the perforation.

Problems to be Solved by the Invention The single cutter type has the disadvantage that if the perforation of the continuous sheet of paper deviates from the cut position of the cutter, the continuous sheet of paper will be cut at a portion other than the perforation.

The burst method has a structure in which the continuous paper is separated by tearing it, so it has the disadvantage that it requires a large force when separating. Furthermore, if a situation such as the contact portion of the burster against the continuous sheet of paper deviates from the perforation line occurs, the continuous sheet of paper will be drawn in the direction in which the burster enters, resulting in a burst failure.

Means for Solving the Problems The invention described in claim I provides a continuous paper separation method in which a perforation portion of continuous paper and a blade are opposed to each other, and the continuous paper is separated by bringing the blade into contact with the perforation. In the device, the edge of the blade that contacts the continuous paper was rounded. Here, "roundness" means the roundness of the blade when viewed from the perforation direction of continuous paper.

The invention according to claim 2 has the following advantages over the invention according to claim 1:
The cutting edge of the blade was formed in such a shape that it contacted the continuous paper from both sides or from one side before the center. Here, "center" and "side" mean the center and side of the blade when viewed from a direction perpendicular to the perforations of the continuous paper.

In the invention described in claim 1, the continuous paper is separated by bringing the blade into contact with the perforation and tearing it from the perforation. At this time, due to the roundness of the cutting edge of the blade, the contact resistance between the blade and the continuous paper is reduced, and the continuous paper is separated with a small force. Furthermore, since the blade portion of the blade is not a sharp edge, even if the blade comes into contact with a portion of continuous paper other than the perforation, the blade will not be cut from the portion other than the perforation.

In the second aspect of the invention, when separating the continuous paper, the contact position of the blade against the continuous paper shifts from the edge of the perforation opening where separation is easiest to the center. Therefore, continuous paper is separated with less force.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 5. This embodiment is an example in which the separation device 1 is used in a boarding pass issuing machine 3 that issues a boarding pass 2 for an aircraft. That is, two paper cases 5 are provided at the bottom of the main body case 4, and continuous paper 6 is stored in these paper cases 5 folded at the perforations 6a. Also,
Inside the main body case 4, there are a plurality of guide plates 7 for guiding the continuous paper 6 to a predetermined path, and these guide plates 7.
A plurality of conveyance rollers 8 are provided between the two conveyance rollers 8 . Here, these conveyance rollers 8 are a pair of rollers that support the continuous paper 6, and have a structure that conveys the continuous paper 6 by rotating in opposite directions. Next, the separation device 1, the encoder 9, and the printer 10 are provided in this order during the conveyance of such continuous paper 6. This printer 10 is composed of a platen loa, and a thermal head 10b that comes into contact with the platen loa via the ink ribbon lla stored in a ribbon cassette 11 and the continuous paper 6. and,
A ticket issuing port 12 and a stocker 13 are provided as the final points to which the continuous paper 6 is guided after passing through the printer 1O, and a switching plate 14 for switching the conveyance direction of the continuous paper 6 is provided at either of them. Furthermore, the encoder 9 is also provided with a paper feed port 15 for feeding the boarding pass 2 backwards.

Next, the separation device 1 is composed of a blade 16 and a drive section 17 that drives the blade 16.

The blade l6 is formed by bending a flat member at a right angle in the middle thereof, and has a contact portion 18 attached to one end and a blade portion 16a formed at the other end. The blade portion 16a has a rounded shape when viewed from the side, and has a concave shape at the center and slopes toward both ends when viewed from the front. FIG. 3 shows the shape of the blade portion 16a seen from the side, and FIG. 4 shows the shape of the blade portion 16a seen from the front. Then, the blade l6 has its blade portion 16a facing the continuous paper 6, and
It is held so that it can move forward and backward in the direction perpendicular to the . moreover,
A spring 19 is connected to the blade l6 to apply a biasing force in the direction of the continuous paper 6. On the other hand, as the drive section 17, the contact section l of the blade l6
A cam 20 is provided at a position where 8 abuts, and this cam 20
A transmission gear 2l is attached to the camshaft 20a, and a timing belt 24 is connected between the transmission gear 21 and the drive gear 23 attached to the drive shaft 22a of the drive motor 22.
is being passed over. Furthermore, a clutch 25 and a trigger drum 26 are attached to the camshaft 20a, and a trigger 27 is engaged with the trigger drum 26. Here, this trigger 27 is connected to the trigger drum 26.
When engaged, the clutch 25 is disengaged, and when disengaged, the clutch 25 is engaged. The driving force of the drive motor 22 is not transmitted to the cam 20 when the clutch 25 is disengaged, but is transmitted to the cam 20 when the clutch 25 is engaged.

Further, the drive motor 28 that drives the conveyance roller 8 is
The drive motors 28 on both sides of the blade 16 are electrically connected to a control unit 29 that controls the operation thereof, and the drive motors 28 on both sides of the blade 16 are electrically connected to the paper fixing means 30 in the control unit 29. It is connected. This paper fixing means 30 fixes the rotors (not shown) of the drive motors 28 by sending a signal to the drive motors 28, and stops the free rotation of the conveyance rollers 8 on both sides of the blade l6. .

Furthermore, as shown in FIG. 5, the continuous paper 6 becomes the boarding pass 2 by being separated at the perforation 6a. This boarding pass 2 has finer perforations 2a, with the center part being the boarding pass body 3l, one end being the boarding pass 32, and the other end being the stub 3.
It is said to be 3. Note that the perforations 6a have large cuts at both ends.

In such a structure, the continuous paper 6 held in the paper case 5 is guided along a predetermined path along the guide plate 7 by the conveyance roller 8. In the process, it is separated from the perforation 6a by the separating device 1, magnetically recorded by the encoder 9, and printed by the printer 10, thereby forming the boarding pass 2. Then, by switching the switching plate 14, the boarding pass 2 is issued from the ticket issuing slot 12 or stored in the stocker 13.

Next, in the separating device l, the perforation 6a of the continuous paper 6 and the blade portion 16a of the blade l6 are made to face each other, and the blade l6 is driven by the drive portion l7 to press the blade portion 16a against the perforation 6a. The continuous paper 6 is separated from the perforation 6a. More specifically, at a position where the blade portion 16a and the perforation 6a face each other, a stop signal is sent from the control unit 29 to the drive motor 28, the conveyance roller 8 is stopped, and the conveyance operation of the continuous paper 6 is stopped. . Then, a signal is sent from the paper fixing means 30 to the drive motor 28, and the rotors of the swing motors 28 on both sides of the blade 16 are fixed. As a result, the conveyor rollers 8 on both sides of the blade 16
The continuous paper 6 held between these transport rollers 8 is fixed. In this state, the trigger 27 is disengaged from the trigger drum 26. Then, the clutch 25 is engaged, the driving force of the drive motor 22 is transmitted to the cam 20, and the cam 20 rotates. As a result, the contact portion l8 of the blade 16 is displaced downward, and therefore the blade portion 16a is also moved downward, thereby pressing the perforation 6a of the continuous paper 6, and removing the continuous paper 6 from the perforation 6a. To separate.

When cutting the continuous paper 6, first, both ends of the blade portion 16a of the blade l6 enter into both ends of the cut perforation 6a. Then, as the blade l6 moves downward, the perforations 6a are separated from the weakest end portions toward the center portion. Therefore, the continuous paper 6 is separated with a small force. Moreover, the fact that the continuous paper 6 can be separated with a small force means that the blade portion 16 of the blade l6
The fact that a is rounded also contributes. This is because the roundness of the blade portion 16a reduces the contact resistance between the blade portion 16a and the continuous paper 6.

Additionally, perforations 6a are provided for the blade portion 16a of the blade l6.
If the blade portion 16a is displaced, the blade portion 16a will come into contact with a portion other than the perforation 6a. In such a case, the blade part 1
Since the cutter 6a is not sharp, the continuous paper 6 will not be cut from a portion other than the perforation 6a. Moreover, since the blade portion 16a is rounded, the contact resistance with the continuous paper 6 is small, and the continuous paper 6 is held fixedly by the conveyance rollers 8 on both sides of the blade l6. Even if the perforation 6a is slightly misaligned with respect to the blade portion 16a, the continuous paper 6 will still have the weakest perforation 6.
It is reliably separated from part a.

Next, a modification of the blade 16 is shown in FIG.

That is, the blade portion 16a of the blade I6 is formed in a shape that is inclined from one end toward the other end when viewed from the front. As a result, when cutting the continuous paper 6, the blade portion 16a of the blade 16 enters the perforation 6a from one end thereof, and the perforation 6a is separated from the other end.

Effects of the Invention The invention according to claim 1 provides a continuous paper separation device in which a perforation portion of continuous paper and a blade are opposed to each other, and the continuous paper is separated by making the blade contact the perforation. The edge of the blade that comes into contact with the paper is rounded, making it possible to separate continuous paper with a small amount of force.
Therefore, it is possible to separate continuous paper with a small driving force and without causing burst failure, and the continuous paper is not cut at any part other than the perforation, and the continuous paper is reliably separated from the perforation. It has the effect of being able to be separated.

The invention according to claim 2 has the following advantages over the invention according to claim 1:
Since the cutting edge of the blade is shaped to contact the continuous paper from both sides or one side before the center, the continuous paper will begin to separate from the edge of the perforation where it is most likely to separate, and therefore the smaller It has the effect of being able to reliably separate the continuous paper from the perforated portion by force.
