[Detailed Description of the Invention] [Field of the Invention] The present invention relates to an apparatus for discharging paper pieces by cutting and discharging a tape formed in a roll, such as a roll of stamps.

[Prior art and its problems]

(Prior Art) As shown in FIG. 1, a conventional paper piece discharging device that discharges a roll-shaped tape as a paper piece, such as a stamp discharging device, is capable of discharging paper strips from a roll stamp 1, which is a roll-shaped tape, along the path of the stamp. A guide roller 2, a micro switch 3 are provided, and a motor 4 is provided.
A feeding roller 5 and a spring 6 driven by
A pressure roller 7 is provided which is pressed against the delivery roller 5 by a pressure roller 7 . Also provided along the route of the stamps are a perforation detector 8 consisting of a photoelectric switch for detecting perforations in the stamps that are marks to be separated, and a cutter 9 for cutting the rolled stamps. As shown in Fig. 2, a rolled stamp has a leader tape portion, which is painted black, for example, at the front end S _A and the end end S _C , and the official stamp is printed only on the middle part S _B. The leading edge S _A is to prevent dirt from being soiled during storage or handling, and the trailing edge S _C is to prevent printed genuine stamps from remaining in the ejecting device when the entire volume has been ejected. It is something. In addition, in order to ensure that the stamps just before the end S _C are ejected when the roll of stamps is finished being ejected, a detection hole S _H is provided at the end S _C to detect the border with the stamp section S _B , as shown in Figure 2. is provided. A microswitch 3 shown in FIG. 1 detects this detection hole _SH .

In such a conventional paper ejection device, when the number of stamps to be ejected is given to a control circuit (not shown), the motor 4 is driven, the perforation detector 8 counts the number of stamps to be ejected, and when the required number is reached, the paper is cut. 9 is driven to eject the stamps. When the microswitch 3 detects the detection hole S _H of the stamp roll 1, it stops discharging stamps after discharging a predetermined number of stamps.

(Problem that the invention attempts to solve) Now, in such a conventional paper ejection device,
When loading a new roll of tape, the operator pulls out its front end S _A and presses the feed roller 5.
and the pressure roller 7, and the cutter 9 is operated to visually cut off the front end S _A. In this case, it is necessary to cut the tape at the position of the mark of the regular paper piece to be ejected, and the loading operation is complicated and time-consuming. Furthermore, in the past, it was necessary to provide a detection hole at the end of the rolled tape, which had the disadvantage of increasing the number of tape manufacturing steps.

[Technical issues]

The present invention was developed to solve the problems of conventional paper ejecting devices, and it is easy to initially load a tape formed in a roll shape such as a roll of stamps, and is also capable of detecting the end of the tape. The technical challenge is to eliminate the need for holes.

[Structure and effect of the idea]

(Means for Solving the Problems) The present invention provides a tape that is formed in a roll shape and has marks for separating paper pieces at predetermined intervals, and has a leader tape section at the front end and end of the tape that does not release as paper pieces. This is a paper strip discharging device that separates and discharges paper strips, as shown in FIGS. 3 and 4,
A feeding roller that sequentially feeds out the tape from the front end, a mark sensor that detects the leader tape part of the tape, a mark detection means that is provided in the tape feeding path and detects the mark on the tape, and a mark sensor that detects the predetermined position of the paper piece of the tape. A cutter that cuts the tape is placed at a distance equal to the number of pieces of paper, and when loading the tape, after the signal from the mark sensor is no longer given, the feed roller is moved until the mark detection means gives pulses equal to the number of pieces of paper between the mark sensor and the cutter. A control means that operates the cutter by driving the cutter, and stops ejecting the paper pieces when a signal from the mark sensor is given at the end of the tape and a pulse corresponding to the number of paper pieces between the mark sensor and the cutter is given from the mark detection means. It is characterized by including the following.

(Function) According to the present invention having such characteristics, after the mark sensor no longer detects the leader tape portion of the tape when loading the tape, the mark detection means outputs pulses corresponding to the number of pieces of paper between the mark sensor and the cutter. When given, the cutter is operated to cut the tape. Then, the front end of the leader tape portion can be cut off and the tape can be attached to the paper strip ejecting device. Also, at the end of the tape, when a leader tape detection signal is obtained from the mark sensor, a pulse corresponding to the number of paper strips between the mark sensor and the cutter is detected, and when that many paper strips have been released, the release of paper strips is stopped. ing.

(Effects) Therefore, according to the present invention, the tape can be loaded into the paper strip discharging device extremely easily without the hassle of loading the tape as in the conventional method. Further, since the leader tape portion at the end of the tape is also detected by the mark sensor and the end of the tape can be detected, there is no need for a detection hole in the tape itself, and the number of tape manufacturing steps can be reduced.

[Explanation of Examples]

(Configuration of Embodiment) The configuration of the present invention will be described below with reference to the drawings. FIG. 3 is a block diagram showing a roll stamp discharging device according to an embodiment of the present invention;
Parts that are the same as those in the figure are given the same reference numerals. In this embodiment as well, a guide roller 2 is provided along the path of the rolled stamp 1, which is a tape, and a feeding roller 5 driven by a motor 4 and a pressure roller 7 that presses the rolled stamp 1 against the feeding roller 5 are provided. provided. The roll stamp 1 is formed in a roll shape similar to the conventional example described above, and has perforations that serve as marks for separating each stamp at predetermined intervals, and has a front end S _A and a terminal end S as shown in FIG. _C has a black leader tape section that will not be released as a regular stamp. The official stamp is printed on the middle part S _B. The rolled stamp 1 used in this embodiment is one that is not provided with a detection hole S _H for detecting the boundary between the stamp portion S _B and the terminal end S _C. A perforation detector 8, which is a mark detection means for detecting a mark (perforation) that separates the paper pieces of the tape, is further provided along the path of the roll stamp 1. A cutter 9 is provided at the position. Katsuta solenoid 1
0 is for attracting the cutter drive lever 11 when the cutter 9 is operated. The cutter drive lever 11 is an L-shaped lever with the right side of the cutter 9 attached to its end, and is rotatably held around a shaft 11a. disconnected. Now, in the present invention, a mark sensor 12 is provided behind the guide roller 2. The mark sensor 12 is composed of, for example, a reflective photoelectric switch or a color detector, and is a sensor for detecting the leader tape portion colored black at the front end S _A and the end end S _C of the roll stamp. It is assumed that the mark sensor 12 and the cutter 9 are spaced apart by a predetermined number of stamps to be ejected, for example, 10 stamps. Further, the micro switch 13 is different from the micro switch 3 shown in FIG. 1 in that it detects breakage of the stamp roll.

Next, the electrical configuration of the roll stamp discharging device according to this embodiment will be explained with reference to the block diagram of FIG. The output of the perforation detector 8 is the sensor amplifier 14
The outputs of the mark sensor 12 and the micro switch 13 are also supplied to the control circuit 15 via the control circuit 1.
given to 5. Furthermore, a conveyance switch 16 (not shown in FIG. 3) conveys the roll stamp along the route.
Also connected to the control circuit 15 is an operation circuit 17 for inputting various data such as the number of stamps to be released. The output of the control circuit 15 is applied to the motor 4 and cutter solenoid 10 via drive circuits 18 and 19, respectively.
The control rotation 15 drives the motor 4 via the drive circuit 18 to convey the rolled stamp 1, and also counts the output of the perforation detector 8 based on the output of the mark sensor 12 as described later and controls the cutter solenoid. 10 constitutes a control means for controlling the cutting of the stamp. The display 20 is for notifying various states of the paper ejection device.

(Operation of the Embodiment) Next, the operation of this roll stamp discharging device when loading a roll stamp will be described with reference to the waveform diagram of FIG. 5. When loading, first pull out the front end S _A of the roll stamp 1, and then move the guide roller 2 and micro switch 1.

In this way, the roll of stamps 1 will be continuously fed out by the feeding roller 5, and as shown in FIG. can get. In Figure 5a, the time
At t ₂ , the mark sensor 12 detects the front end S of the roll stamp 1.
This is the time when the passage of _A is detected, and from this time the control circuit 15 starts counting the detection signal of the perforation detector 8 as shown in FIG. 5b. and corresponds to the number of stamps between the mark sensor 12 and the cutter 9.
The motor 4 is stopped at time _t3 when the 10th pulse is obtained, and the cutter solenoid 10 is then operated. Then, since the distance between the mark sensor 12 and the cutter 9 is set to 10 stamps, the cutter 9
Accordingly, only the front end S _A of the roll stamp 1 can be cut off.

Thereafter, the required number of stamps are fed out, cut, and released based on the data provided by the operating circuit 17, as in the conventional example described above. When the roll stamp 1 approaches its end and the mark sensor 12 detects the leader tape section of the end S _C of the roll stamp 1, the perforation detector 8 starts counting the number of output pulses again. After that, when 10 stamps are released, the number of stamps to be released in the roll of stamps 1 ends, so the display 20 indicates that the stamps are out. If the rolled stamp breaks midway, it will be detected by the micro switch 13, and the display 20 will display this fact.

Although this embodiment has been described with respect to a device for discharging rolled stamps, the present invention can be applied not only to rolled stamps but also to discharging devices for various pieces of paper such as revenue stamps and tickets.
