Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a paper feeding device having a cutting mechanism for cutting paper.

2. Description of the Related Art Conventionally, a paper feeding device that feeds paper in one direction and stops it, cuts the paper with a movable blade, and issues the cut pieces as tickets, etc. has a first paper feeding section, a movable blade, and a second paper feeding section. There is one in which two paper feed units are sequentially arranged from the upstream side to the downstream side along the paper conveyance path. In this type of device, only the cut pieces cut by the movable blade are issued in advance, so it is necessary to drive the first paper feeder on the upstream side and the second paper feeder on the downstream side independently. There is.

In order to meet this requirement, the first and second paper feeding sections are connected to separate feed motors, and the first and second paper feeding sections are driven by one feed motor, but the first and second paper feeding sections are driven by one feed motor. Some machines are equipped with an electric clutch in the power transmission path with the paper feeding section.

Problems to be Solved by the Invention However, the former method requires two feed motors, which increases the cost, and when driving the first and second paper feeders at the same time, the circumferential speed and stop of each feed motor are high. It is difficult to match the timing, which affects the paper feeding operation. Furthermore, the latter requires an electric clutch in the power transmission mechanism, which complicates the structure and increases cost.

Means for Solving the Problems The first invention includes a first paper feeding section comprising a feed roller and a pinch roller rotatably supported on an arm, a movable blade connected to a cutter drive section, and a first paper feeding section comprising a feed roller and a pinch roller rotatably supported on an arm; and the second paper feeding unit are sequentially arranged from the upstream side to the downstream side of the paper conveyance path,
The first and second paper feed sections are connected to one feed motor, the arm is connected to an arm drive section, and operation timings of at least the feed motor, the cutter drive section, and the arm drive section are set. The present invention is characterized in that it is provided with an operation timing setting circuit.

The second invention is characterized in that a pinch roller is disposed below the feed roller.

A third aspect of the present invention is characterized in that a cutter solenoid is used as the cutter drive section, and an energizing voltage reducing means is provided for stopping the return operation of the cutter solenoid midway.

Effects: In the first invention, the first and second paper feeding sections are driven by one feed motor, thereby transporting the paper, and when the feed motor is stopped, the cutter driving section is driven and movable. The paper is cut by the blade, and when the feed motor is driven again, the arm is displaced by the arm drive unit, so the pinch roller of the first paper feed unit is separated from the feed roller, so that only the cut pieces are It will be issued as a ticket, etc.

In the second invention, since the pinch roller is disposed below the feed roller, the paper is always supported by the pinch roller by its own weight, and therefore the paper is lifted from the feed roller by its own weight at the moment the pinch roller is separated from the feed roller. It separates and immediately stops from the conveyed state.

In the third invention, the movable blade is driven by the cutter solenoid to cut the paper, and then the voltage applied to the cutter solenoid is lowered, so that the movable blade is temporarily stopped at a position where it interferes with the paper transport path. Therefore, even if the paper comes into contact with the feed roller, it comes into contact with the movable blade that functions as a shutter and is kept in a stopped state.

Example An embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, a paper conveyance path 1 is provided.

The downstream side of this paper conveyance path 1 is branched into an exit 2 connected to a ticket storage section (not shown) and the other exit 3, and at the branch point, a path switching plate 5 connected to a switching solenoid 4 is provided. is provided rotatably around a support shaft 6. Further, along the paper conveyance path 1, a first paper feed section 7, a cutting mechanism 9, and a plurality of second paper feed sections 8 are sequentially arranged from the upstream side to the downstream side. The first paper feeding section 7 consists of a feed roller 11 and a pinch roller 12 connected to a feed motor 10, and the second paper feeding section 8 consists of a feed roller 13 and a pinch roller 14 connected to a feed motor 10. It becomes more. The cutting mechanism 9 includes a movable blade 16 driven by a cutter solenoid 15, which is a cutter drive unit, and a fixed blade 17 facing the edge of the movable blade 16. Reference numeral 18 denotes a ticket, which is a sheet of paper conveyed through the paper conveyance path 1. Although not shown, perforations are formed on the ticket 18 at predetermined intervals.

FIG. 3 shows the structure of the cutting mechanism 9. A lever 21 that rotates around a support shaft 20 is rotatably connected to the plunger 19 of the cutter solenoid 15, and a spring 2
Both ends of a link 24 are rotatably connected to the lever 21 and the movable blade 16, which is biased upward by the lever 2 and pivots about the support shaft 23.

As shown in FIG. 4, the pinch roller 12 of the first paper feed section 7 rotates about a support shaft 25 and is rotatably supported by an arm 26 biased by a torsion spring 27 to feed the paper. It is in resilient contact with the roller 11. This arm 26 is an arm solenoid 2 which is an arm driving section.
It is rotatably connected to the plunger 29 of No. 8. The pinch roller 14 of the second paper feed section 8 is rotatably held by a support shaft 30 and rotatably supported by an arm 32 biased by a torsion spring 31, so that the pinch roller 14 is elasticized by the feed roller 13. have been in contact with.

Next, the feed motor 10 and cutter solenoid 15
FIG. 7 shows an operation timing setting circuit 33 that sets the operation timings of the arm solenoid 28 and the switching solenoid 4.

That is, the CPU 34 and the R in which the program is written.
OM35 and R where various data to be changed are written.
The AM 36 and an input port 39 to which a sensor 37 for detecting the ticket 1 and a control switch 38 for inputting an operation mode and the like are connected are connected to each other by an address bus and a data bus. Furthermore, a switching solenoid control circuit 40 that drives the switching solenoid 4, a motor control circuit 41 that drives the feed motor 10, a cutter solenoid control circuit 42 that drives the cutter solenoid 15, and an arm solenoid that drives the arm solenoid 28. A control circuit 43 is connected to the CPU 34 via a data bus. Furthermore, an interface transmission circuit 4 for connection with a host computer 44
5 is connected to the CPU 34 by a data bus.

In such a configuration, the operation of each part will be explained with reference to the timing chart shown in FIG. 2 and the flow chart shown in FIG. 8. First, the feed motor 1o is driven and the ticket 18 is conveyed.

This state is the state shown in FIG. When the tip of the ticket 18 reaches the sensor 37, the sensor 37 is turned on. This is the position where the perforation of the ticket 18 faces the edge of the movable blade 16, and the feed motor 10 is stopped by the detection signal of this sensor 37, and the ticket 18 is stopped (time A in FIG. 2). Cutter solenoid 15 according to this period
is energized. The energizing voltage at this time is 24 V, and the movable blade 16 descends below the paper path 1 by the suction action of the plunger 19 of the cutter solenoid 15 and cuts the ticket 18 on the perforation. Next, arm solenoid 2
8 is energized, the arm 26 is pulled by the plunger 29 and rotates clockwise, and the pinch roller 12 is separated from the feed roller 11. Then, at time C in FIG. 2, the energizing voltage of the cutter solenoid 15 is lowered to 5V, and the movable blade 16 is stopped at a position that blocks the paper conveyance path 1, and functions as a shutter. This step (2) in the flowchart of FIG. 8 is the energizing voltage reducing means according to claim 3, and the circuit that performs this operation is a chopper circuit (not shown) of the cutter solenoid control circuit 42. Next, the feed motor 1o rotates,
Feed rollers 11.1 of the first and second paper feed sections 7, 8
3 is driven. However, in the first paper feeding section 7, the pinch roller 12 is separated from the feed roller 11, so there is no conveying force for the ticket 18, and the second paper feeding section 8
Only the first half of the cut stub of the ticket 18 is transported. In this state as shown in FIG. 5, the switching solenoid 4 is energized at the timing shown in FIG. As a result, the first half of the ticket 18 is stored in the ticket storage section from the exit 2. At this time, the feed roller 11 of the first paper feeding section 7 is rotating, but the pinch roller 12
is located on the lower side, the second half of the ticket 18 separates from the feed roller 11 due to its own weight and is supported by the pinch roller 12, and even if the ticket 18 floats for some reason and comes into contact with the feed roller 11. Even if this happens, since the movable blade 16 functions as a shutter, it is possible to reliably prevent a mistake in which the second half of the ticket 18 is conveyed following the first half. In addition, the movable blade 16
The circuit is energized in order to function as a shutter, but since the energizing voltage is as low as about 5 volts, no unreasonable load is applied to the circuit. Subsequently, at time E shown in FIG. 2, the cutter solenoid 15 is de-energized, so the movable blade 16 returns upward by the biasing force of the spring 22. At this time, the cutter solenoid 15
Since the voltage applied to the movable blade 16 was low, the influence of residual magnetism was small, and the movable blade 16 returned quickly. Then, at time F in FIG. 2, the arm solenoid 28
The energization is stopped, and the arm 26 is rotated counterclockwise by the biasing force of the torsion spring 27, as shown in FIG.
The pinch roller 12 contacts the feed roller 11 elastically. As a result, the second half of the ticket 18 is transported, but the switching solenoid 4 is de-energized until time G in FIG. The second half of the ticket 18 is ejected from the exit 3. After this discharge operation, the feed roller 10 is stopped.

As described above, the first and second paper feeding sections 7 and 8 can be driven by one feed motor 10.

Further, the feed motor 10 is connected to the first and second paper feeding sections 7.
, 8, there is no need to provide an electric clutch in the power transmission path leading to them, thereby simplifying the structure.

Note that the present invention is also applicable to cutting sheets and transporting them intermittently along the same route.

That is, the route switching plate 5 and the switching solenoid 4 that drives it are not essential.

Effects of the Invention Since the present invention is constructed as described above, it is possible to eliminate the need for the feed motor that drives the first and second paper feeding sections, and it is also possible to cut the paper using the movable blade and then restart the feed motor. When driving, the arm drive section can displace the arm to separate the pinch roller of the first paper feeding section from the feed roller, and thereby an electric clutch is connected between the feed motor and the first paper feeding section. It is possible to stop the paper conveyance function of the first paper feeding section without providing a paper feeding section, and to reliably separate only the cut pieces of paper and issue them with the second paper feeding section. By arranging the pinch roller of the paper feeding section below the feed roller, the paper can be separated from the feed roller and quickly stopped from the conveyed state at the moment the pinch roller is separated from the feed roller, and further, By using a cutter solenoid as the cutter drive unit and providing an energizing voltage reducing means to stop the return operation of the cutter solenoid midway through, it is possible to temporarily maintain the movable blade in a stopped state in the paper transport path after cutting the paper. Therefore, even if the paper comes into contact with the feed roller, the paper can come into contact with the movable blade that functions as a shutter and be reliably maintained in a stopped state. Therefore, the effect of separating the cut pieces of paper is further improved. It has the effect of ensuring that
