Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a cutting device which is internally configured in an automatic ticket vending machine used in station service, for example, and more specifically, a plurality of cutting devices can be used on a ticket-issuing sheet during transportation. The present invention relates to a cutting device that inserts a cut line at a location and performs ticketing processing.

(B) Conventional technology In recent years, when issuing a perforated ticket such as a perforated number-of-staples ticket, the paper is perforated while the ticket-issuing paper is conveyed to shorten the ticketing time and improve printing performance. Since the perforation processing means for improvement is highly efficient, its adoption is desired. In this case, it is important to rotate the perforation rotary cutter in synchronization with the transportation speed of the ticket-issuing paper.

However, in the case of inserting a large number of perforations at an equal pitch such as a spelled number ticket, the perforations cannot be inserted at a predetermined pitch unless the rotation cycle of the perforation rotary cutter matches this pitch. Therefore, the invention can be applied only to a specific ticket type having a pitch corresponding to the rotation cycle of the perforation rotary cutter, and the ticket issuing process corresponding to multiple ticket types cannot be performed.

(C) Problem to be Solved by the Invention The present invention controls the speed of rotation of a rotary cutter during cutting processing (including perforation processing) for cutting at least a part of the paper while conveying the ticket-issuing paper. It is therefore an object of the present invention to provide a cutting device capable of forming cut lines corresponding to a predetermined cut line pitch on ticket issuing paper.

(D) Means for Solving the Problem The present invention is a rotary cutter provided with a cutter, which is rotated in synchronization with the conveyance speed of a ticket-issuing paper at the time of processing of cut edges and cuts at least a part of the paper, in a part of a rotating body. , A cutting device for inserting a plurality of cuts into a ticket-issuing paper to issue a ticket, wherein a motor for driving the rotary cutter and a motor for transporting the paper are provided independently, and the rotary cutter rotates for cutting In the region, the cut rotation cutter is rotated in synchronization with the transportation speed of the ticket-issuing paper, and in the rotation region in which the cutter after cutting does not contact the ticket-issuing paper, the rotation speed is synchronized with the transportation speed. It is a cutting device provided with a speed control means for controlling to rotate at a different rotation speed.

(E) Effect of the Invention According to the present invention, in the cut processing rotation region, the rotary cutter is rotated by the speed control means in synchronism with the conveyance speed of the ticket-issuing paper, and the cut-cut processing is performed in the course of conveying the ticket-issuing paper. be able to.

In the free rotation range (the rotation range in which the cutter does not contact the paper), the speed control unit causes the rotary cutter to rotate in a non-synchronized manner (a rotation speed different from the rotation speed that rotates in synchronization with the paper conveyance speed). Since the gear shift control can be performed at high and low speeds, it is possible to rotate at a rotation speed corresponding to the next cut processing position and correspond to the cut processing position.

For this reason, it is possible to make cuts at predetermined long and short pitches according to the ticket type, and to make sure that the cuts are made at predetermined positions on the ticket-issuing paper without being restricted by the rotation cycle of the rotary cutter or the ticket type. You can In other words, since the rotary cutter can be rotated at a speed higher or lower than the sheet conveyance speed, there is an effect that the pitch of cuts can be freely changed.

The printed contents corresponding to each ticket are printed with, and the ordinary ticket is discharged to the saucer 17 through the ordinary ticket discharge / conveyance path 16, and the large ticket is perforated by the perforation device 18, and then the large ticket. Discharge transport path 19
The spliced coupons are similarly discharged to the tray 17 through the perforation device 18 and then subjected to perforation processing as an example of the cut processing in which at least a part of the paper is cut by the perforation device 18, and then the coupon ticket is discharged and conveyed. It is discharged to the saucer 17 through the passage 20.

The ordinary ticket discharging / conveying path 16 has a leading end side connected to a feeding section of the roll paper 12 via a cutter device 14 and a printing device 15, and a trailing end side from which a lower ticket discharging port 21 communicating with an external tray 17 is connected.
On the other hand, the slant connection is made in a straight line. By connecting in a straight line, the ticket is discharged at the shortest discharging distance, and the ticketing time is shortened.

A common starting end of the large-sized ticket discharging / conveying path 19 and the number-of-times ticket discharging / conveying path 20 is connected to the starting end side of the ordinary ticket discharging / conveying path 16, and the first distribution plate 22 is connected to the connection branch portion. The first distribution plate 22 controls distribution to either the ordinary ticket side 16 or the perforation ticket side 19, 20.

In addition, the large-sized ticket discharging / conveying path 19 corresponds to the position of the above-mentioned first distribution plate 22 on the starting end side, and at the subsequent stage, a comb-tooth-shaped sewing machine that rotates in synchronization with the conveying speed of the roll paper 12 at the same speed. A perforation device 18 having an eye-rotating cutter 23 (see FIG. 4) is provided, and the end side thereof is connected to the intermediate portion of the ordinary ticket discharging and conveying path 16 described above.

Further, the above-described multi-pass ticket discharging / conveying path 20 has a perforation device 18 having a starting end side common to the starting end side of the large-sized ticket discharging / conveying path 19 described above.
Is connected to the rear stage side, and the terminal side is inclinedly connected to the ticket outlet 21 below.

In addition, a second distribution plate 24 is provided at a branch portion between the large-sized ticket discharge / conveyance path 19 and the multiple-number ticket discharge / conveyance path 20 that are commonly connected, and the distribution control is performed on one of the conveyance paths 19 and 20. To do.

In this case, the coupon ticket discharge / conveyance path 20 includes the first and second distribution plates.
It is formed in a relatively long transport path via 22, 24, but this transport length is provided in a sufficiently long transport path suitable for the length of the coupon ticket, and the tip of the coupon is in the middle of discharging the coupon ticket. There is no possibility of causing a conveyance obstacle such as contacting the tray 17 of the ticket outlet 21.

In the figure, S1 is an ordinary ticket detection sensor, S2 is an ordinary large-sized ticket detection sensor, S3 is a splicing number ticket detection sensor, M1 is a discharge motor, M2 is a conveyance motor, M3 is a perforation motor, and 25 is a third collection roller. A distribution plate, 26 is a conveyance roller, and 27 is a conveyance guide member.

By the way, as shown in FIGS. 3 to 6, the above-described perforation device 18 is provided with a comb-tooth-shaped perforation rotary cutter 23 that forms perforations during the conveying process.
It is provided so that the roll paper 12 guided to the perforation device 18 rotates at a rotation speed that is synchronized with the conveyance speed, and perforations are formed while the perforation device 18 is passing.

In this perforated rotary cutter 23, comb-shaped cutters 29 having a roll paper width length are fixed to both side planes of a flat plate-shaped rotary shaft 28 serving as a rotating body in such a manner that each screw 30 is divided into two equal parts in the circumferential direction. Each time the plate-shaped rotary shaft 28 is fixed and half-turned, the tip edge of the comb-tooth cutter 29 abuts the surface of a cylindrical tooth 31 described later, and the roll paper 12 passing between them is perforated. To process.

In this case, since the perforation rotary cutter 23 is rotated in the same direction as the transport direction of the roll paper 12 so as not to overload the bill face, a smooth perforation with good quality and good perforations can be obtained. You can

Then, the perforated rotary cutter 23 is replaced with the gate-shaped frame 32.
A cylindrical cylindrical tooth 31 in a free state, which is supported on the upper part of the frame and receives the comb tooth cutter 29 on the lower part opposite to this,
Support in. Both end portions of these are rotatably supported by a gate-shaped frame 32, and the frame 32 is arranged at a common starting end portion of the large-sized ticket discharging / conveying path 19 and the number-of-times ticket discharging / conveying path 20.

The rotational force of this perforated rotary cutter 23 is
One axis portion of the flat plate-shaped rotary shaft 28 extending to one side is rotated by receiving the driving force of the perforation motor M3 via a rotary drive device (not shown).

Further, a rotating plate 33 for positioning the comb-teeth cutter is attached to one shaft portion of the flat plate-shaped rotating shaft 28 extending to the side,
The rotary plate 33 is provided with two notch detecting portions 34 formed in a fan shape along the outer peripheral edge in two positions in the circumferential direction corresponding to the above-described comb tooth cutters 29, 29. A photoelectric detection type rotational position detection sensor S4 for photoelectrically detecting the rotational position of the notch detection unit 34 with the outer peripheral edge of the U-shaped being sandwiched is disposed,
The rotation position of the comb cutter 29 is detected.

By detecting the rotational position of the comb-tooth cutter 29, the comb-tooth cutter 29 is stopped after rotation of the perforations and is in a standby position P1 where it waits, and the comb-tooth cutter 29 is rotated further forward than the standby position P1 to rotate the comb teeth. The cutter 29 performs position control at a rotation start position P2 that starts rotation corresponding to a predetermined perforation processing position of the roll paper 12.

In this case, the rotational position detection sensor S4 is set to the standby position P1 when the cutout detection portion 34 of the rotating plate 33 is in the light-transmitting state, and is rotated forward from the position to change the light-transmitting state. The rotation start position P2 is set to the position that has changed to the translucent state.

Further, the notch detection unit 34, the notch amount in a fan shape, for example,
The cutout is relatively large at about 30 °, which allows a wide light transmission allowable angle and a wide setting allowable range of the standby position P1. Therefore, even if the perforation rotary cutter 23 is slightly rotated, it is maintained within the set range of the standby position P1.

Furthermore, when the operator sets the initial setting position of the perforation rotary cutter 23, the light transmission allowable area as the standby position P1 may be set so as to be detected by the rotational position detection sensor S4. The setting adjustment of the eye rotation cutter 23 becomes extremely easy.

Figure 1 shows the block diagram of the control circuit of the perforation device, CP
The U61 controls each circuit device according to the program stored in the ROM, and stores the control data in the RAM and reads it.

The print control circuit 62 receives the ticket issuing signal from the CPU 61, outputs it to the printing device 15 to drive the thermal head, and transfers it to the transport motor M2 side in synchronization with the printing sequence (heating, cooling) of thermal printing. Output a drive pulse signal.

The conveyance motor control circuit 63 receives a signal from the print control circuit 62 described above, and also receives a ticket issuing signal from the CPU 61,
The conveyance motor M2 is drive-controlled to start, stop, and a predetermined conveyance speed according to the ticket type.

The timer circuit 64 counts the drive pulse signal of the carry motor M2 to accurately grasp the carry position of the roll paper 12, and when the ticket reaches the perforation processing position corresponding to the rotation start position P2, the perforation Times when processing is completed.

At this time, while the perforation processing position of the roll paper 12 is being conveyed from the position corresponding to the rotation start position P2 to the perforation processing completion position, a synchronization signal is input to the AND circuit 65 as a perforation processing operation. The drive pulse signal of the carry motor M2 is applied to the perforation motor control circuit 66, and the perforation motor M3 is rotated in synchronization with the carry motor M2.

The perforation motor control circuit 66 is directly connected to the timer circuit 64.
The drive pulse signal of the perforation motor M3 is given to position control the perforation rotary cutter 23 to the standby position P1 and the rotation start position P2, and from the perforation processing completion position to the standby position P1 and the rotation start position P2. Performs rotation control.

In this case, in the rotation range in which the perforation rotary cutter 23 performs perforation processing, the perforation motor M3 is driven in synchronization with the pulse signal for driving the transport motor M2, whereby the perforation rotary cutter 23 transports the roll paper 12. It is rotated in synchronization with the speed, but in the rotation range from the perforation processing completion position to the rotation start position P2, the perforation motor M3 is started, stopped, and unsynchronized in accordance with printing or perforation pitch that is different for each ticket type. A desired perforation is formed by controlling the speed to be a high speed or a low speed (a rotation speed different from the rotation speed that rotates in synchronization with the sheet conveyance speed).

In particular, when continuously forming perforations with a short pitch on a splicing coupon, the free rotation area (the rotation area where the cutter 29 does not contact the paper) that rotates after perforation processing is rotated at high speed, The control is performed so as to correspond to the short pitch of the machining position. In the figure, 67 is an OR circuit.

The operating state of the cutting device thus configured will be described with reference to FIG.

Now, there are many short-pitch perforations 71 as shown in FIG.
In the case of issuing the number-of-staples ticket 72 containing ..., the conveyance motor M2 is driven based on the ticket generation signal of the number-of-staples ticket 72 being input in the first step 81, and the roll paper 12
Is fed for a predetermined length, and the printing content corresponding to the required number-of-bindings ticket 72 is printed on the rolled-out roll paper 12 by the printing device 15, and the roll paper 12 is guided to the transport path on the perforation device 18 side.
With this carrying operation, in the second step 82, the rotation position detection sensor S4 confirms whether or not the position of the comb tooth cutter 29 is at the standby position P1, and if it is not set at the standby position P1, an error occurs. If it is determined that the staff processing is performed and the waiting position P1 is set, in the third step 83, the perforation motor M3 is driven to position the comb tooth cutter 29 at the rotation start position P2 in the rotation direction front side. Rotate to. Then, in the fourth step 84, the rotation position detection sensor S4 is shielded from the light transmitting state, and the position of the comb tooth cutter 29 is changed to the rotation start position P2.
When it is detected that the roll paper 12 has been set to, in the fifth step 85, the drive of the perforation motor M3 is stopped and the rotation start position P2 is waited, and in the sixth step 86, the perforation of the roll paper 12 conveyed is perforated. When the processing position comes to a position corresponding to the comb tooth cutter 29 to be perforated, the perforation motor M3 is changed to the transport motor M2 in the seventh step 87.
The paper is rotated in synchronism with the conveyance speed to form perforations on the roll paper 12.

In this case, for the roll paper 12 guided to the perforation device 18, the perforation rotary cutter 23 starts to rotate at a timing corresponding to the perforation cutting position, as shown in FIG. As shown in the drawing, the comb tooth cutter 29 makes circumferential contact with the surface of the cylindrical tooth receiving tooth 31 to make a perforation on the bill surface. Predetermined number of pulse signals during this period (120 pulses) Perforation rotary cutter 23
When is rotated, the perforation processing is completed, and in the eighth step 88, it is determined whether or not the perforation processing is the total number of processing times of 10 times set in the splicing coupon, and the final 10 If it is not perforation processing, in step 9 89, the perforation motor M3 is rotated at a high speed for a predetermined number of pulse signals (240 pulses), and the perforation rotation cutter 2
3 is positioned at the rotation start position P2 that skips the standby position P1.

This is because the perforation pitch is short, and this pitch is shorter than the half cycle of the perforation rotary cutter 23.

Then, from the rotation start position P2, the perforation rotary cutter is again used.
23 is rotated in synchronization with the transport speed of the roll paper 12 to perform perforation processing, and if this perforation processing is the final tenth time, it is determined that all processing of perforations is completed, and in the tenth step 90, The perforation rotary cutter 23 is rotated by a predetermined number of pulse signals (200 pulses), and position control is performed so that the detection light is transmitted to the fan-shaped notch central portion of the notch detection unit 34, and the next perforation is performed. Prepare for processing.

Then, the perforated number-of-stamps ticket 72 is cut into a predetermined number of stapled-number tickets by the cutter device 14, and then receives the sorting action to receive the lower tray through the number-of-times ticket discharge / conveyance path 20. Released to 17.

In this case, without pausing the roll paper 12,
Since it is perforated while being conveyed, it has a good print finish, and is particularly suitable for continuous printing of long-number spliced tickets.

As described above, in the perforation processing rotation range, the perforation rotation cutter rotates in synchronization with the transport speed of the roll paper, and in the free rotation range, the perforation rotation cutter corresponds to the next perforation processing position. Since it can be rotated at a high speed of non-synchronization, perforations can be formed at a predetermined short pitch.

In the above-described embodiment, the perforation pitch shorter than the rotation cycle in which the perforation rotation cutter 23 makes a half rotation has been described as an example, but the present invention is not limited to this, and the perforation pitch is longer than the rotation cycle. However, the perforation can be formed by the position control operation of the standby position P1 and the rotation start position P2.

In the correspondence between the configuration of the present invention and the above-described embodiment, the cutting device of the present invention corresponds to the perforation 71 of the embodiment. Similarly, the ticket issuing paper corresponds to the roll paper 12, and the cutter is the comb. Corresponding to the tooth cutter 29, the rotary cutter corresponds to the perforated rotary cutter 23, the speed control means corresponds to the control circuit such as the timer circuit 64 and the perforated motor control circuit 66, and the motor for driving the rotary cutter is Corresponding to the perforation motor M3, the paper conveying motor corresponds to the conveying motor M2, and the rotating body corresponds to the flat plate type rotary shaft 28. However, the present invention is limited to the configuration of the above-described embodiment. It is not something that will be done.
