Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ticket issuing device used in, for example, an automatic ticket vending machine, which issues a ticket by carrying out, cutting, and printing a rolled paper.
[0002]
[Prior art]
The ticket issuing device corresponds to one ticket by sandwiching the leading end portion of a roll of rolled paper (hereinafter referred to as roll paper) between a pair of rotating feed rollers (feeding rollers) at the time of ticketing. Send out a specified length, cut, and then print on the surface of the ticket. The feed roller has a structure in which one roller is made of metal and rubber is baked on the surface of the roller, and the other roller is made of metal, and a notch is provided on the contact surface to sandwich the sheet.
[0003]
Further, since the ticket has a magnetic part for writing magnetic information on the back surface, necessary magnetic information as a ticket is written in the magnetic part after cutting. Since the roll paper used here takes a large number of issued tickets per roll, the outer diameter of the roll core disposed in the center for use in attaching to the ticket issuing device is made as small as possible. The outer diameter is made as large as possible. For this reason, the difference in outer diameter between the beginning and end of use of the roll paper increases, and the outer diameter increases at the beginning of use and decreases at the end of use.
[0004]
[Problems to be solved by the invention]
If the feed force is increased by increasing the pinching force by the feed roller by the above-described mechanism of the feed roller, the surface of the ticket may be damaged, and the printing on the ticket surface and the magnetic part of the ticket surface may be adversely affected. In addition, the rubber part of the feed roller was also heavily worn, and the surface of the rubber deteriorated and the feed force was not always constant. When the number of issued tickets is small, the stop time of the feed roller is long, and the position pressed against the opponent does not change for a long time. Therefore, there is a problem in life such that the rubber portion of the feed roller is deformed at the contact position.
[0005]
In addition, when the roll paper is loosened, a part of the roll paper roll is shifted laterally (in the direction of the side of the roll paper), and the roll misalignment hits the side guide of the roll paper and the roll paper rotates. Resistance torque is generated. When a roll deviation occurs at a location where the outer diameter of the roll paper is large, even if the resistance force caused by the roll paper hitting the side guide is the same, compared to when a winding deviation occurs at a location where the outer diameter is small, Large rotational load torque.
[0006]
Therefore, the rotational load torque tends to vary depending on the location where the winding deviation occurs. In addition, even if the radius of the roll-off location is the same, if the number of roll paper rolls is different, the resistance will vary due to the difference in how the slipped sheet paper hits the guide. The load torque will also vary.
[0007]
Therefore, a large variation occurs in the rotation of the roll paper obtained by subtracting the load torque from the rotation torque of the motor for driving the feed roller, that is, the rotation torque used for feeding the ticket. Therefore, the roll paper feed speed varies and the amount of ticket paper fed varies, and as a result, there is a case where a ticket with a certain length cannot be issued.
[0008]
Therefore, an object of the present invention is to provide a ticket issuing device that can stabilize the quality of a ticket to be issued, can make the length of the ticket constant, and has a long life of a feed roller.
[0009]
[Means for Solving the Invention]
In order to achieve the above object, as shown in FIGS . 1 , 4 and 5 , a ticket issuing device according to the invention according to claim 1 has a holding portion 3a for holding a roll of ticket paper 2a, b. b; and a transport unit 4 that transports the sheet papers 12a and b fed out from the holding units 3a and b; the transport unit 4 includes a feed roller 6 that applies a transport force to the fed sheet papers 12a and b; Ceramic coating is applied to the outer periphery of the feed roller 6 that comes into contact with the fed ticket 12a, b; the holding portions 3a , b are formed by rolling the ticket 2a , b rolled into a roll. It is configured to hold rotatably about a rotation axis passing through the center of the paper 2a , b ; and the holding portions 3a , b further include a plurality of side rollers 32a , b arranged in series ; rollers 32a, covers b are ticket paper 2a which is wound into a roll, the substantially central portion of the side surface to the side of b to the outer peripheral portion Contact Te, nearly parallel to the plane perpendicular to the rotation axis, characterized in that it is rotatably disposed shaft 34a, around b through the vicinity of the rotary shaft.
[0010]
If comprised in this way, since the ceramic coating which has high intensity | strength was given to the outer peripheral part of a feed roller, abrasion and a deformation | transformation decrease compared with a rubber-made feed roller, for example. Also, by applying ceramic, the contact surface becomes finer than when, for example, a metal feed roller is cut, so the friction coefficient increases and the contact portion is less likely to deteriorate. Therefore, the feed force of the feed roller can be increased and the feed force can be maintained without excessively increasing the force of sandwiching the sheet of the feed roller.
Therefore, in the ticket issuing device of the present invention, even if the feed roller comes into contact with the surface of the ticket, the pinching force has little influence on the printing of the ticket and the magnetic information writing part of the ticket, and is stable and stable over the long term. A ticket of length can be issued.
[0011]
Since the side roller is disposed on the side surface of the roll paper (rolled ticket) as described above, the side roller rotates in contact with the side surface along with the rotation of the ticket paper, and rotates with the ticket paper. The side load applied to the paper can be reduced. Further, the side roller functions to suppress the slip of the roll paper from shifting in the lateral direction of the roll. Therefore, since the ticket issuing apparatus of the present invention can keep the load resistance of the roll paper small and constant, a ticket having a certain length can be issued.
[0012]
Since the number of side rollers is plural, the slip on the side rollers can be reduced, and the rotational load torque of the roll-shaped ticket can be reduced.
Furthermore, since the plurality of side rollers arranged in series are arranged as described above, it is possible to prevent winding slippage in the width direction of the ticket and to keep the rotational load resistance of the roll-like ticket small and constant. Therefore, the ticket issuing apparatus of the present invention can issue a ticket having a certain length.
[0013]
The ticket issuing apparatus according to the present invention includes: a holding unit that holds a sheet of paper wound in a roll; and a transport unit that conveys a sheet of paper fed out from the holding unit; The holding portion has a side roller; the side roller is in contact with a side surface of the sheet of paper wound in a roll shape, and the rotation shaft is attached to the rotation shaft. It may be characterized in that it can be rotated around an axis that is parallel to a substantially orthogonal plane and passes in the vicinity of the rotation axis.
[0015]

[0016]
FIG. 1 is a schematic front sectional view showing an embodiment of a ticket issuing apparatus according to the present invention. The ticket issuing apparatus 1 is provided with a ticket sheet formed by winding a strip-shaped ticket sheet in which magnetic information can be written on the back surface, that is, a roll sheet 2a, b (2a for FIG. 3A). The roll papers 2a and 2b are held vertically by the holding portions 3a and b, and are arranged side by side (see FIG. 3A). The roll paper 2b is arranged on the front side in the figure, and the roll paper 2a is arranged on the other side of the roll paper 2b in the figure. The roll papers 2a and 2b pass through the centers thereof, and on the support shafts 21a and b (21a refer to FIG. 3A) as the rotation shafts of the present invention provided in the holding portions 3a and b, the guides 22a and The movement in the horizontal direction is restricted by b and is held rotatably. The roll paper 2b is sandwiched between guides 22a and 22b that are attached to the side surface of the holding portion 3b. Here, the guide 22a is disposed between the roll paper 2a and the roll paper 2b.
[0017]
The guides 22a and 22b have rotating shafts disposed on the shafts 34a and 34b, and cylindrical side rollers 32a and 32b arranged in series, respectively, are attached to the side surfaces of the roll paper 2a and b as follows. Each is in contact with each other. That is, the side roller 32a is in contact with the side surface of the roll paper 2a and the side surface of the roll paper 2b, and the side roller 32b is in contact with the side surface of the roll paper 2b opposite to the side surface in contact with the side roller 32a (FIG. 3). (See (a)). The shafts 34a, b of the side rollers 32a, b are arranged in a substantially radial direction of the roll paper 2a, b (see FIGS. 4 and 5).
[0018]
The roll papers 2a and 2b are separated from the highest part of the roll-shaped part and moved in the horizontal direction as strip-shaped ticket sheets 12a and b, and further changed in the vertical downward direction by the guide roller 31 and will be described later. Head to the transport section 4. In the vicinity of the lower portion in the vertical direction of the guide roller 31, sensors 14a and b for detecting the presence or absence of the sheet 12a and b at this place are provided in the holding portions 3a and b. The sensors 14a, b are used to detect that the loaded roll paper 2a, b is in a state immediately before it is used up.
[0019]
The ticket issuing apparatus 1 includes handles 24a, b and detachable push buttons 25a, b. The grips 24a, b are used to slide the holding portions 3a, b in the direction of the arrows in the drawing when replacing the roll papers 2a, b, and the holding portions 3a, b are pushed by pressing the detachable push buttons 25a, b. Can be slidable.
The ticket issuing apparatus 1 further supports rails 26a, b that support the load applied to the holding portions 3a, b and guide the holding portions 3a, b during sliding, and the ticket 12a fed out from the holding portions 3a, b, a transport unit 4 that selectively transports b as described later.
[0020]
The transport unit 4 is arranged at the lower part of the roll paper 2a, b held in the vertical direction, and the strip-shaped ticket sheets 12a, b are horizontally moved by the entrance rollers 58a, b of the transport unit 4 when entering the transport unit 4. The direction is changed to the direction until it passes through the transport unit 4 and is fed out in this direction.
[0021]
The ticket issuing apparatus 1 includes a guide roller 15 that guides the ticket sheets 12a and 12b transported from the transport unit 4 to the next stage, and feed rollers 5 and 6 that transport the ticket sheets 12a and 12b with a feeding force. A cutting unit 7 that cuts the paper sheets 12a and 12b after passing through the feed rollers 5 and 6 into a size to be handed to the customer, and a ticket 10 that is cut by the cutting unit 7 (the paper sheets 12a and b are cut into the ticket 10 by cutting). ) Is provided with a printing section 8 for printing necessary information, and magnetic information writing sections 18 and 19 for writing necessary information on the ticket 10 to enable use by an automatic ticket gate or the like. The feed roller 6 is driven by a drive motor (not shown), and the feed roller 5 is configured to follow the feed roller 6 during operation. The feed roller 5 is urged in the direction of the feed roller 6 via a spring (not shown).
[0022]
The ticket issuing device 1 further includes a carry-out unit 9 for carrying out the ticket 10 at the final stage of the device such as the tray 20, and the carry-out unit 9 includes endless belts 16 and 17 that cover the magnetic information writing units 18 and 19, and each roller. It is comprised including. The ticket sheets 12a and 12b that have passed through the guide roller 15 are configured to be directed substantially vertically upward, and the ticket 10 that has been passed through the magnetic information writing units 18 and 19 is configured to be directed substantially vertically downward. The feed roller 6 is the feed roller of the present invention.
[0023]
FIG. 2 shows the structure of the feed roller 6 disposed below the feed roller 5 (see FIG. 1). The feed roller 6 is configured by attaching a metal disc 6A to both ends of a shaft 6B, and ceramic coating is applied to the vicinity of the outer peripheral surface of the disc 6A and the side surface of the disc 6A. The feed roller 5 has the same shape as the feed roller 6 and is entirely made of rubber, or a structure in which rubber is baked near the outer peripheral surface of the part corresponding to the disc 6A and the outer peripheral part of the side surface of the part. It is good to do.
[0024]
Since the feed roller 6 has a ceramic coating on the contact surface with the paper sheets 12a and 12b, unlike the feed roller having a notch on the contact surface with the paper sheet, the pinching pressure with the feed roller 5 can be reduced. Even if it contacts the magnetic part which writes magnetic information without scratching a ticket, this will not be deteriorated. Further, since the outer peripheral surface of the disc 6A is in contact with the vicinity of both end portions of the ticket papers 12a and 12b, the ticket papers 12a and b are surely protected without contacting the central portion for writing the magnetic information of the ticket papers 12a and b. be able to.
[0025]
As described above, since the ceramic coating is applied to the contact surface with the sheet 12a, b on the feed roller 6, fine particles of ceramic can be formed on the roller surface, and per unit area on the contact surface with the sheet 12a, b. Since the bite increases and the bite is caused by fine particles, the friction coefficient between the surface of the feed roller 6 and the ticket can be increased without adversely affecting the ticket 12a, b. Note that the roll paper 2a, b is rotated by the feed roller 6 receiving the feeding of the end portions of the strip-like ticket sheets 12a, b.
[0026]
In addition, since the ceramic coating is applied to the contact surface of the feed roller 6 as described above, the pressing force of the feed roller 5 to the feed roller 6 can be reduced, so the stop time of the feed roller is long when the number of issued tickets is small, Even if the pressed position does not change for a long time, problems such as deformation of the contact portion of the rubber portion of the feed roller 5 with the feed roller 6 are less likely to occur.
[0027]
Next, the configuration of the transport unit 4 will be described with reference to FIGS. 6, 7, 8, and 9. 6 is a schematic plan view of the transport unit 4 according to the embodiment of the present invention, FIG. 7 is a cross-sectional view taken along the line AA in FIG. 6, FIG. 8 is a partially enlarged view of the second transport mechanism 51b in FIG. FIG. 7 is a schematic side cross-sectional view seen from the direction B of FIG. 6.
[0028]
As shown in FIG. 6, the transport section 4 includes a first transport mechanism 51a, a second transport mechanism 51b, and a drive mechanism section 60 that selectively drives one of the two. Both transport mechanisms 51a, b have transport inlets 80a, b and transport outlets 81a, b, and the transport inlet 80a of the first transport mechanism 51a is disposed at a slightly higher position than the transport inlet 80b of the second transport mechanism 51b. (Refer to FIG. 7), and are arranged in a state of being substantially side by side. The transport outlet 81a of the first transport mechanism 51a is disposed at a position slightly higher than the transport outlet 81b of the second transport mechanism 51b (see FIG. 8) and directly above the transport outlet 81b.
[0029]
The drive mechanism unit 60 includes a drive motor 63, and the rotation of the drive motor 63 is caused by the feed roller 64a that is a component of the loading mechanism unit 55a of the first transport mechanism 51a and the component of the loading mechanism unit 55b of the second transport mechanism 51b. It is selectively transmitted to a certain feed roller 64b according to the rotation direction of the drive motor 63.
[0030]
The second transport mechanism 51b operates at the time of loading the sheet 12b, an entrance roller 58b that assists the insertion of the sheet 12b from the holding unit 3b, a transport path 53b composed of a bottom plate 56b, an upper plate 57b, and a side plate. A loading mechanism section 55b, an inlet detection sensor 67b for detecting the presence or absence of the sheet 12b in the vicinity of the conveyance inlet 80b on the conveyance path 53b, and an outlet detection sensor 68b for detecting the presence or absence of the sheet 12b in the vicinity of the conveyance outlet 81b. Consists of.
[0031]
The loading mechanism portion 55b includes a pressing roller 70b, and the pressing roller 70b is biased in the direction of the feed roller 64b by a spring 71b disposed at the tip of the roller bracket 69b, and is driven to the feed roller 64b during operation.
The sheet 12b is bent from a substantially vertical direction to a horizontal direction by an entrance roller 58b, and is sandwiched between the feed roller 64b and the pressing roller 70b along the conveyance path 53b between the bottom plate 56b and the upper plate 57b. It is fed with a feed force. At this time, the roll paper 2b rotates with the aforementioned conveyance.
[0032]
Note that the configuration of the first transport mechanism 51a is substantially the same as that of the second transport mechanism 51b described above, and therefore only different parts will be described below. As a different configuration, first, the first transport mechanism 51a has a point that the tilt of the transport path 53a with respect to the horizontal plane in the width direction is opposite to that of the transport path 53a of the second transport mechanism 51b (see FIG. 7).
[0033]
Next, the rotation direction of the loading mechanism 55a is opposite to the rotation direction of the loading mechanism 55b. Also, a feed roller 64a for loading and exchanging the ticket sheets, and a pressing roller 70a that is urged by a spring 71a (not shown) at the tip of a roller bracket 69a (not shown) and that is driven by the feed roller 64a during operation. Is arranged symmetrically with the feed roller 64b and the pressure roller 70b of the second transport mechanism 51b with respect to the surface of the transport path 53a (the roller bracket 69a and the spring 71a are also similar to the roller bracket 69b and the spring 71a). 71b). The feed rollers 64a and b may be made of metal, and a ceramic coating may be applied to the outer peripheral portion that comes into contact with the ticket sheets 12a and 12b.
[0034]
Next, when one ticket 12b (or ticket 12a) is issued, the other ticket 12a (or ticket 12b) is loaded into the first transport mechanism 51a (or second transport mechanism 51b). The operation of each of the transport mechanisms 51a and b when doing so will be described.
When the sheet 12a is inserted into the first transport mechanism 51a and the sheet 12a is detected by the entrance detection sensor 67a, the drive motor 63 starts to rotate in the J direction (forward direction) in FIG. This rotation causes the feed roller 64a to rotate (in the J1 direction), and loading starts when the leading edge of the ticket 12a is sandwiched between the pressing roller 70a. At this time, in the second transport mechanism 51b, the feed roller 64b is configured to transmit power effectively only in the rotation in the direction opposite to the J direction, that is, in the K direction. Driving is not transmitted to the feed roller 64b and the pressing roller 70b.
[0035]
When the conveyance of the ticket 12a progresses in the conveyance path 53a and the loading of the ticket 12a up to the outlet detection sensor 68a is confirmed by the outlet detection sensor 68a, the drive motor 63 finishes driving and operates by the loading mechanism unit 55a. Ends.
[0036]
The loading operation when the sheet 12b is detected by the entrance detection sensor 67b of the conveyance path 53b and the insertion of the roll paper 2b is confirmed is as follows. The drive motor 63 rotates in the K direction (reverse direction) in FIG. 9 and only the feed roller 64b rotates (K1 direction), so that the sheet is loaded. The other components are the same as in the case of the conveyance path 53a. Operate.
[0037]
Roll paper 2a, b is fed by feeding rollers 64a, b when the paper sheets 12a, b are loaded, and feed rollers 5, 6 at the time of ticket issuance, respectively. Rotates. When the roll paper 2a, b rotates, the side roller 32a of the guide 22a rotates on one side surface of the roll paper 2a, the side roller 32b of the guide 22b rotates on one side surface of the roll paper 2b, and the side roller Since 32a rotates on the other side surface of the roll paper 2b, the rotational load of the roll paper 2a, b can be reduced.
Even when the roll papers 2a and b are loosely wound, the side rollers 32a and b suppress the occurrence of winding misalignment in the width direction, thereby preventing an increase in rotational load torque. Since the side wall (not shown) of the apparatus body faces the other side surface of the roll paper 2a with a slight gap, the roll paper 2a is prevented from being unwound in this direction.
[0038]
The side rollers 32a and 32b of the guides 22a and 22b have the same diameter and length. Since the number of guides 22a and 22b is six, the length of each side roller 32a and 32b is short. Therefore, the speed difference from end to end of one side roller 32a, b is small, the slip generated on the side rollers 32a, b is small, and the rotational load torque can be reduced accordingly. In general, if the number of side rollers 32a, b is increased, the slip on the side rollers 32a, b can be reduced, and the rotational load torque can be reduced.
[0039]
The side rollers 32a and b cover the roll paper 2a and b from approximately the center to the outer periphery. Can be prevented. Instead of the side rollers 32a and b being cylindrical, one truncated cone having an imaginary vertex at the center of the roll may be divided into six at regular intervals, for example.
[0040]
【The invention's effect】
As described above, since the ceramic coating is applied to the outer periphery of the feed roller that contacts the ticket, the coefficient of friction between the feed roller and the ticket increases, so that the feed force is stably supplied via the feed roller. Therefore, the quality of the issued ticket can be stabilized, the length of the ticket can be made constant, and the life of the feed roller can be extended.
[0041]
Since the roller which contacts the side surface of the roll-shaped ticket as described above is provided, so-called winding deviation of the ticket can be prevented, and the rotational resistance of the roll-shaped ticket can be lowered and made constant. Therefore, the length of the issued ticket can be made constant.
