An apparatus, a method, and an automatic ticket gate are provided.

  Automatic ticket gates installed at many ticket gates of various transportation facilities such as railways and airports, and entrances and exits of public facilities, take out or collect the media such as tickets and commuter passes that are inserted by users. A medium conveying device (also referred to as a card handler) that reads data recorded on the medium, writes required data, prints, and other processes. In general, the medium conveying device is a conveying means composed of a belt that sandwiches the front and back surfaces of a loaded medium and a pulley that drives the belt, a detecting means such as a photo sensor that detects the passage of the medium, and reading and writing data to and from the medium.

  Patent Documents 1 and 2 do not mention any means for preventing or suppressing the occurrence of a jam or the like with respect to a technique for dealing with an abnormality such as a jam in a medium transport device of an automatic ticket gate. It is considered that the main cause of the jam or the like in the medium conveying apparatus is deterioration of a belt constituting the medium conveying apparatus or a pulley driving the belt. When the belt or the pulley is deteriorated, the contact pressure between the belts is lowered, the medium conveying speed is greatly reduced, and the medium is not accurately conveyed. As a result, the frequency of occurrence of media clogging in each part of the media transport device and data reading errors or writing errors with respect to the media increases. Further, when the belt progresses and cutting occurs, the medium itself cannot be conveyed.

  In order to prevent such a problem, it is necessary to accurately grasp the state of the medium transport device and perform maintenance at an appropriate time. Conventionally, maintenance workers have determined whether maintenance is necessary by adding experience to the maintenance data statistically obtained from the number of operations of the automatic ticket gate and the number of failures. However, since the maintenance data is posterior data based on past failure occurrence cases, it does not reflect the current state of the automatic ticket gate in operation. In addition, the judgment based on the experience of the maintenance worker may be influenced by various factors such as experience, knowledge and ability. Therefore, in the conventional determination method, there is a possibility that the proper maintenance time of the medium transport device is lost, or on the contrary, unnecessary maintenance work is performed on a sound device.

  An object of the present invention is to provide means capable of quantitatively diagnosing the state of a medium transport device, instead of a conventional determination method based on so-called so-called operator experience and intuition. For this purpose, the automatic ticket gate management device adopted by the present invention is characterized in that the medium conveyance time is determined by using at least two medium detection means arranged along the medium conveyance device of the automatic ticket gate. It has a function to measure, a function to store the obtained time data, a function to calculate using the time data, and a function to output or display the time data or calculation result.

  The management device may have a function of determining whether the maintenance work of the medium transport device is necessary based on the calculation result of the time data, and outputting or displaying the determination result.

  The present invention also provides a method for managing an automatic ticket checker that can achieve the above-mentioned object, characterized in that at least two medium detection units arranged along the medium transfer device of the automatic ticket checker are provided. Measuring the medium transport time using the means, storing the obtained time data, calculating using the time data, and determining whether the maintenance work of the medium transport apparatus is necessary based on the calculation result. .

  If the embodiment of the management device according to the present invention is shown, the medium detection means arranged at the starting end of the feeding portion, the relay portion between the feeding portion and the aligning portion, and the end portion of the aligning portion in the medium conveying device of the automatic ticket gate A function of measuring the feeding time for the medium to pass through the feeding section and the alignment time for the medium to pass through the alignment section based on the detection signal output from the predetermined number of times of conveyance in which the feeding time and the alignment time are set in advance. It is assumed that it has a function for storing the minutes, a function for calculating each average value from the stored feeding times and alignment times for the predetermined number of times of conveyance, and a function for displaying the average values for the calculated feeding times and alignment times on the screen. It is possible.

  In the management device, the function of comparing the average value of the feeding time and the reference value of the feeding time, and / or the function of comparing the average value of the alignment time and the reference value of the alignment time, and the average value When it is determined that the value exceeds the reference value, it is possible to add a function for requesting execution of the maintenance work of the medium transport device.

  In addition, if an embodiment of the management method according to the present invention is shown, the feeding time for the medium to pass through the feeding unit and / or based on the detection signal output from the medium detecting means arranged along the medium conveying device of the automatic ticket gate and / or Alternatively, the alignment time for the medium to pass through the alignment unit is measured, the feeding time and / or the alignment time are stored for a preset number of times of conveyance, and each of the stored feeding time and / or alignment time for the predetermined number of times of conveyance is stored. The average value of the feeding time is compared with the reference value of the feeding time, and / or the calculated average value of the alignment time and the reference value of the alignment time are compared, and the comparison result is Based on this, it is conceivable to adopt a management method for determining whether or not maintenance work for the medium conveying apparatus is necessary.

  Furthermore, the present invention provides an automatic ticket gate equipped with the management device.

  According to the management device and the management method of the present invention, the medium transport time is measured using the medium detection means arranged along the medium transport device of the automatic ticket gate, and the obtained time data or the calculation of the stored time data is calculated. Based on the result, it is determined whether or not maintenance work for the medium transport apparatus is necessary. In other words, the present invention pays attention to the medium conveyance time, and based on this, the state of the medium conveyance device can be quantitatively indicated, so that it is possible to accurately determine whether maintenance such as adjustment work or parts replacement is necessary. It is not influenced by experience, knowledge, ability, etc. Further, since the time data that is the basis of the determination is acquired from the medium conveyance device that is in operation, it accurately reflects the current state of the device, so that an accurate and appropriate determination can be made.

  In addition, the automatic ticket gate provided with the said management apparatus comprised based on this invention can exhibit the said effect.

(Medium transport device)
First, a schematic configuration of a medium conveyance device of an automatic ticket gate to which the present invention is applied will be described. Many automatic ticket gates are installed at ticket gates in various transportation facilities such as railways, airlines, and ships, and entrances and exits in public facilities such as theme parks, amusement parks, zoos, museums, etc. It has a function to limit. In other words, while transporting a boarding pass, boarding pass, admission ticket, commuter pass and other media from the input unit to the take-out unit or the collection unit by the media transport device, necessary processing such as data reading / writing is performed and read. Based on the data, permission or rejection of the passage of the input person is determined, and if it is determined to be rejected, the passage is closed as necessary.

  As shown in FIG. 1, the medium conveyance device X provided in the automatic ticket gate is also called a card handler or simply a handler, and by arranging a pair of endless belts b and b spanned between pulleys p and p facing each other. Conveyance paths R1 to R4 are configured, and the front and back surfaces of a ticket such as a ticket, commuter pass and other media (not shown) are sandwiched between the belts b and b, and the takeout unit 10 (or a collection not shown) is collected. Part). The first transport path R1 following the input section 1 has a feeding section 2, the second transport path R2 has an alignment section 3, and the third transport path R3 has a first reading section 4, a writing section 5, and a fifth. 2 is provided with a reading unit 6, an insertion unit 7 and a printing unit 8, and a bill collection unit 9 and an extraction unit 10 are provided in the fourth transport path R4. A reversing unit 11 and a pool unit 12 are provided between the first reading unit 4 and the writing unit 5 in the middle of the third transport path R3.

  The feeding unit 2 has a function of separating and feeding one by one when a plurality of media are stacked and loaded. The alignment unit 3 adjusts the posture of the medium to a predetermined state so that subsequent processing is appropriately performed. The first reading unit 4 is a part for reading data written on the medium, and is composed of two reading heads H1, H2 arranged so as to sandwich the transport path R3 vertically, and one head H1. Is for reading the data of the loaded medium with the back side up, and the other head H2 is for reading the data of the medium loaded with the top side facing up. The writing unit 5 includes a writing head H3 for recording or rewriting required data on the medium, and the second reading unit 6 includes a verification head H4 for confirming the content of data written on the medium. The reversing unit 11 is a mechanism for reversing the medium loaded with the back side up so that the front side becomes the upper side. As a result, the heads H3 and H4 on the downstream side of the reversing unit 11 are connected to the transport path R3. It only needs to be arranged on the lower side. The pool unit 12 is a mechanism for holding the remaining medium in the apparatus while performing a required process on one of the media separated by the feeding unit 2 when a plurality of media are loaded. . The insertion part 7 is a part for punching holes in the medium as required, and the printing part 8 is a part for printing predetermined characters and sentences on the medium as needed. The bill collection unit 9 is a mechanism for collecting and summing up a plurality of inserted media after sequentially processing them. The take-out unit 10 is for discharging the processed medium from the apparatus and returning it to the user. Although not shown in the figure, a collecting unit that collects a medium that does not need to be returned to the user is formed at the end of the transport path in which another transport path is formed following the end of the third transport path R3. Is provided.

  Usually, the medium transport device X is provided with a medium detection means for detecting the passage position of the transported medium. In FIG. 1, medium detection means S <b> 1 to S <b> 4 are arranged in the medium feeding unit 1, the starting end of the feeding unit 2, the relay unit between the feeding unit 2 and the aligning unit 3, and the terminal unit of the aligning unit 3. The state is illustrated. The medium detection means is preferably a sensor that can accurately detect a medium moving at high speed without contact, and an optical sensor such as a photo sensor or a photoelectric switch is representative. When the medium detecting means is a transmissive photosensor composed of a projector and a light receiver, the medium is detected by the medium blocking the detection light projected by the projector. The medium detecting means S1 of the loading unit 1 is configured by arranging a plurality of photosensors so that the size of the medium can be determined from the range of the photosensors that are blocked when the medium is loaded.

  Based on the medium detection signals output from the medium detection units S1 to S4, the control device C operates the motors (not shown) that drive the belts b and the pulleys p constituting the transport paths R1 to R4, and the data for the media The operations of the heads H1 to H4 that read and write are controlled, and the operations of the insertion unit 7 and the printing unit 8 are controlled. Further, the control device C determines whether or not the medium thrower can pass based on the data read by the first reading unit 4, and when it determines that the control is not possible, the control device C closes the passage with a door or the like provided in the automatic ticket gate or It also has a function of outputting a command for operating an alarm.

  Next, the operation when the medium transport device X is applied to an automatic ticket gate installed at a ticket gate of a railway will be described. The series of operations of the medium transport device X is controlled by the control device C in principle. When a user inserts a medium such as a ticket or a commuter pass into the input unit 1, the first medium detection means S1 detects the input of the medium and the dimensions of the medium and outputs a detection signal. Based on this detection signal, the feeding unit 2 takes in the medium and sends it to the alignment unit 3. Also, the medium type is determined based on the medium dimension data. When a plurality of media are loaded in an overlapping manner, the feeding unit 2 separates them one by one. In order to improve the smoothness of the medium conveyance and improve the read / write efficiency by the subsequent heads H1 to H4, the medium is corrected to a predetermined posture by the alignment unit 3 and then sent to the first reading unit 4 in the conveyance path R3. . During this time, passage of the medium is detected by the medium detection means S2 to S4. The detection signal is output to the control device C, and the position is confirmed.

  For the medium sent to the transport path R3, the recorded data is read by the first reading unit 4, subsequently the ticket checking information is written by the writing unit 5, and the written data is verified by the second reading unit 6. Then, if necessary, punch holes are formed in the medium by the insertion portion 7, and necessary characters / words are printed by the printing portion 8. When the medium is inserted face down, after passing through the first reading unit 4, it is reversed by the reversing unit 11 so that the surface is directed upward. When a plurality of media are input, the subsequent media are temporarily held in the pool unit 12 while the processing of the preceding media among the media separated by the feeding unit 2 is executed. 9 is summarized. Thereafter, the medium is returned from the take-out unit 10 to the user via the transport path R4. Alternatively, the medium that is determined not to be returned is sent to the collection unit from another conveyance path connected to the aggregation unit.

(Management device and management method)
By the way, in the medium conveyance device X of the automatic ticket gate, a jam occurs when the contact pressure between the belts b and b is not appropriate due to deterioration of the belt b or the pulley p constituting the conveyance path or poor adjustment thereof. It becomes easy. It is known that the occurrence frequency of jam is high in the feeding unit 2 and the alignment unit 3. Therefore, in this embodiment, the medium passing time of the feeding unit 2 and the aligning unit 3 is measured by the management device K provided at an appropriate position of the automatic ticket gate, and the state of the medium transport device X is determined based on the obtained time data. It was decided to monitor.

  The management device K includes a storage device such as a memory and a calculation device such as a CPU inside a box-shaped housing 20 as shown in FIG. 2A, and a display unit 21 including a liquid crystal display or the like on the outer surface. An operation unit 22, data input / output units 30, 31 and the like are provided. As shown in FIG. 2B, the operation unit 22 is provided with buttons 23 to 28 for selecting items to be displayed on the display unit 21. The button 23 is for switching to the data display of the feeding unit 2, and the button 24 is for switching to the data display of the alignment unit 3. Buttons 25 to 28 are used to select display items. The data input / output units 30 and 31 are connected to the control device C and an external central management center. Normally, the medium detection signals output from the medium detection means S2 to S4 are set so as to be input to the control device C in a collective manner. The medium detection signal is transferred from the control device C to the management device K. However, according to the situation, it is not prohibited to connect the management device K directly to each medium detection means S2 to S4 without mediating the control device C.

  The management device K configured as described above sequentially stores the detection signals output from the medium detection units S2 to S4 in the storage device when the medium is transported. Then, according to the procedure shown in FIG. 3, the time required for the medium to pass through the transport path R <b> 1 (feeding time) from the difference between the medium detection times in the medium detection means S <b> 2 and S <b> 3 arranged at both ends of the feeding unit 2 by the arithmetic device. T1) is calculated. On the other hand, the time required for the medium to pass through the transport path R3 (alignment time T2) is calculated from the difference between the medium detection times of the medium detection means S3 and S4 arranged at both ends of the alignment unit 3. The feeding time T1 and the alignment time T2 are stored in the storage device for a predetermined number of times of media conveyance (for example, 2000). In addition, since the medium (for example, a commuter pass and a regular ticket) from which a dimension differs has a difference in the passage speed of the delivery part 2 and the alignment part 3, the delivery time T1 and alignment time T2 of a medium (for example, a commuter pass) of a specific dimension are produced. It may be set to select and store only. Alternatively, for each type of medium, it may be set so that the average value of the feeding time T1 and the alignment time T2 can be displayed. The medium type can be determined by the medium detection unit S1 of the input unit 1. Alternatively, the data read by the first reading unit 4 after passing through the alignment unit 3 may be fed back to the management device K through the control device C and used to determine the medium type.

  Based on the data of the feeding time T1 and the alignment time T2 stored in the management device K in this way, the state diagnosis of the medium transport device X and the necessity of maintenance are determined. When a medium (for example, a large-sized ticket such as a commuter pass) is inserted in a medium transport device X of an automatic ticket gate, the normal average value of the feeding time T1 is about 180 ms (milliseconds), and the alignment time T2 Is a normal average value of about 215 ms (milliseconds). When the values of T1 and T2 calculated by the management apparatus K are larger than the average value by an allowable value (for example, 5 ms), that is, when T1 ≧ 185 ms and T2 ≧ 220 ms, the medium conveying device X detects a jam or a medium. The frequency of failures such as errors increases. Therefore, the necessity of maintenance work is determined by checking the state of the medium transport device X by a diagnostic procedure as shown in FIG. 4 at the time of periodic inspection or emergency repair. That is, the display unit 21 of the management device K displays the average value of the feeding time T1 and the alignment time T2 for each predetermined number of times of medium conveyance (for example, 100 conveyances) (display switching between the feeding time T1 and the alignment time T2 is performed by the operation unit). 22 buttons 23 and 24), the operator confirms this. When the average value of the feeding time T1 and the alignment time T2 is smaller than the reference value (normal average value + allowable value) (T1 <185 ms, T2 <220 ms), it is determined that no maintenance is necessary, and inspection of each part is performed. After the inspection, the inspection / repair is completed. If the average value of the feeding time T1 or the alignment time T2 is equal to or greater than the reference value, it is determined that there is an abnormality such as belt or pulley deterioration, and necessary maintenance work such as belt or pulley replacement or contact pressure adjustment is performed. Good.

  Each numerical value shown above is an example, and may be appropriately changed according to the model, installation status, usage mode, and the like of the medium transport device X. In particular, it is necessary to set the normal average value of the feeding time T1 or the alignment time T2 and the reference value for determining the necessity of maintenance based on the measurement of the actual machine. In addition, the size of the population for calculating the average value can be changed as appropriate (for example, every 50 times, every 200 times, etc.). Furthermore, if necessary, the maximum value / minimum value of the feeding time T1 or the alignment time T2 may be stored and used as a judgment material.

(Maintenance mode)
By the way, the management device K may be used in the following manner. The management device K displays the feeding time T1 and the alignment time T2 for each medium conveyance, or the medium conveyance 2 in addition to the normal mode for displaying the average value of the feeding time T1 and the alignment time T2 for every 100 medium conveyances. A maintenance mode that displays the average value / maximum value / minimum value of the feeding time T1 and the alignment time T2 at an arbitrarily designated number of times up to 99 times can be adopted. The maintenance mode can be used for checking the state of the apparatus after carrying out periodic inspection, emergency repair, overhaul, etc. of the medium transport apparatus X. That is, the recovery state of the medium transport device X can be quantitatively evaluated by comparing the feeding time T1 and the alignment time T2 with the reference values with the minimum number of times of transporting the medium. Conventionally, confirmation after maintenance is left to the operator's sense of observing the presence or absence of jams and errors, so the degree of recovery of the state of the device cannot be determined quantitatively. There was a risk of recurrence soon. On the other hand, since the present invention quantitatively evaluates the recovery state of the medium transport device X, it is possible to suppress the recurrence of a jam error.

[Other Embodiments]
The management device K not only displays the average value of the feeding time T1 and the alignment time T2, but also compares this average value with a preset reference value, resulting in a defective state where the average value is greater than or equal to the reference value. In some cases, this may be displayed on the display unit 21 and notified by optical means (LED, pilot lamp, etc.) or acoustic means (buzzer, chime, voice, etc.). Alternatively, it is also possible to provide a central management center or the like outside and notify the above-mentioned defective state by appropriate communication means.

  Moreover, the management device K can be applied to an existing automatic ticket gate because it is possible to exert the effects of the present invention only by being mounted on a conventional automatic ticket gate and connected to the control device. is there. Alternatively, when a new automatic ticket gate is manufactured, the management apparatus according to the present invention can be integrated.

  In the above-described embodiment, the feeding time T1 and the alignment time T2 are used as materials for determining the necessity of maintenance in the medium transport device X. However, the medium detection is also performed in the transport paths R3 and R4, the reversing unit 11, and the pool unit 12. It is not impeded that a means is provided and the medium conveyance time of each part is measured and used as a judgment material.

(A) is a perspective view showing an example of the management apparatus according to the present invention, and FIG. (B) is a front view showing a display unit and an operation unit of the management apparatus.
