Description

  The present invention relates to a core tube and a long material processing apparatus.

  In recent years, medicines prescribed in medical institutions can be automatically packaged one by one on wrapping paper by using a medicine packaging device for the purpose of improving work efficiency. In addition, a medicine bag for containing the packaged medicine is also a prescription in which predetermined information such as the patient's name, the number of medicines to be accommodated, and the dosage method is inputted from the terminal by using a medicine bag printing device. Based on this, printing is automatically started.

  For this reason, a plurality of the wrapping paper and medicine bags wound around a cylindrical core tube in the state of a long material are collectively supplied to a medical institution. The core tube around which the long material is wound is attached to a medicine packaging device or a medicine bag printing device, and the long material is sequentially rewound, and processing such as medicine packaging or printing is performed according to each device. The used core tube is stored in a predetermined position, and is periodically replaced with a core tube not using the long material.

  Regarding the supply time of the core tube and the maintenance time of the long material processing apparatus to which the core tube is attached and detached, the provider side periodically checks the stock status of the core tube and the operation status of the long material processing device, The current situation is dealing with it.

  However, the amount of long material used is affected by hospitals and seasonal differences, and is not necessarily constant. For this reason, it is necessary for the provider side to predict the replacement time of the core tube and to make a plan for the production and supply of the core tube. However, this prediction is difficult, and the more medical institutions to provide, the more the plan Is troublesome. In general, on a long material for a medicine bag, information determined by prescription such as the number of medicines and a medication method is printed by a medicine bag printing device, and a hospital name or the like is printed in advance. Therefore, when an order is received after there is no unused core tube, there is a problem that the supply is delayed and the treatment at the hospital is hindered.

  In addition, the maintenance of the long material processing equipment was performed at the same time as the replacement of the core tube. However, the service is uneven between the place where the core tube is frequently replaced and the place where it is not, and the maintenance takes time. For this reason, there exists a problem that the replacement | exchange operation | work of a core pipe cannot be performed smoothly.

  Furthermore, when a long material processing apparatus breaks down, if it is dealt with after receiving a notification, the packaging of medicines and the printing of medicine bags cannot be performed, and there is also a problem that the work at medical institutions is hindered.

  Furthermore, the conventional core pipe has a cylindrical shape made of plastic or the like, and has a hollow space, so there is a problem that the occupied space is large. Therefore, when the number of core tubes to be stored increases, the storage space for other items is restricted, and in some cases, a reusable core tube is discarded. In particular, in the core tube used in the medicine bag manufacturing and printing apparatus, since the outer diameter cannot be made smaller than a certain size because it is necessary to avoid the wrapping paper from being curved, the problem of the storage space becomes significant. . Moreover, the width dimension of the wrapping paper used for the packaging of the medicine is not necessarily constant, and there is a problem that a core tube is required for each different width dimension.

  Therefore, the present invention predicts the replacement time of the core tube and the maintenance time of the device by observing the usage status of the long material and the operating status of the device, and the core tube and the long length capable of taking appropriate measures. It is an object to provide a material processing apparatus.

  In order to achieve the above object, according to the present invention, a long material is wound on the provider side, mounted on a long material processing apparatus on the user side, and when the long material is used, it is collected on the provider side. A communication unit that transmits and receives a signal carrying information, a storage unit that stores the information, and information that is received by the communication unit is stored in the storage unit, and the information that is stored in the storage unit And a control unit that transmits the information via the communication unit, and the information includes information related to the long material processing apparatus received from the long material processing apparatus.

  The information stored in the storage unit preferably includes a machine number for determining whether or not the long material processing apparatus to be mounted is appropriate.

  Multiple outer diameter members are connected to each other so that they can be rotated sequentially. All of them can be connected to form a cylindrical shape so that a long material can be wound. Is preferable.

  The outer diameter member is composed of a plurality of side members arranged in parallel and facing each other at a predetermined interval, and connecting beams for connecting the side members, and the number of the side members and connecting beams is a long material to be wound. It is preferable that it can be changed according to the width dimension.

  It is preferable to provide an outer surface member that is attached to the connection beam and constitutes an outer surface around which the long material is wound, and that reinforces the side members and prevents the connected outer diameter member from falling off.

  In order to achieve the above object, the present invention is a long material processing apparatus in which the core tube is detachably provided and performs a predetermined process on a long material wound around the core tube. The apparatus includes a processing information detection unit that detects information and a transmission unit that transmits processing information detected by the processing information detection unit to the communication unit of the core tube.

  When the processing information detected by the processing information detection unit is transmitted to the core tube by the transmission unit and cannot be stored in the storage unit of the core tube, a storage unit is provided for storing the processing information as accumulated data. Is preferred.

  As is clear from the above description, according to the core tube of the present invention, if processing information such as the usage status of the long material and error data in the long material processing apparatus is generated, this processing information is all It can be stored in the storage unit. Therefore, an appropriate maintenance plan can be made based on the stored data.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows an overall view of a long material distribution management system. This long material distribution management system generally includes a core tube 1 to which a transponder 14 is attached, a core tube collection processing device 32 for exchanging information with the transponder 14 of the core tube 1, and a core tube 1 as described below. It is composed of a medicine packaging device 34 and a long material processing device 33 such as a medicine bag printing device 35 to be supplied.

  The core tube 1 is formed by connecting a plurality of outer diameter members 2 in a cylindrical shape, and a long material 21 serving as a medicine wrapping paper or a medicine bag is wound around the outer periphery thereof. As shown in FIGS. 2 (a) and 2 (b), the core tube 1 can be developed in a planar shape by releasing one connection portion of each outer diameter member 2 when not in use.

  As shown in FIG. 3, each outer diameter member 2 is composed of a plurality of side members 3 arranged in parallel and facing each other at a predetermined interval, and connecting beams 4 that connect the side members 3 to each other. . As shown in FIG. 4, a shaft portion 6 protrudes from one end portion of each side member 3 in a recess 5 formed on one surface, and a rotation restricting convex portion 7 around the shaft portion 6. And the rotation control recessed part 8 is formed, respectively. Further, as shown in FIG. 5, a bearing portion 9 is formed at the other end of each side member 3. The bearing portion 9 is formed by drilling a through hole 10 a in a recess 10 formed on the surface opposite to the shaft portion 6. In the recess 10, an escape recess 11 is formed from the outer edge toward the through hole 10 a, and a rotation restricting receiving portion 12 protrudes at a position facing the escape recess 11. The relief recess 11 is formed so as to gradually increase in width from the bearing portion 9 toward the edge of the side member 3, and can easily guide the shaft portion 6 to the bearing portion 9 during assembly described below. And the rotation control convex part 7 can be welcomed now. On the other hand, the rotation restriction receiving part 12 enters the rotation restriction recessed part 8 in a state where the shaft part 6 is engaged with the through hole 10 a of the bearing part 9. In other words, in a state where the outer diameter member 2 is connected to form a flat shape, the rotation restriction receiving portion 12 and the rotation restriction convex portion 7 are respectively brought into contact with one wall 8a and 11a of the rotation restriction concave portion 8 and the relief concave portion 11, respectively. In contact with the outer diameter member 2 in a cylindrical shape, the rotation restriction receiving portion 12 and the rotation restriction convex portion 7 are in contact with the other walls 8b and 11b of the rotation restriction concave portion 8 and the relief concave portion 11, respectively. Further rotation is prevented. Further, at the edge of each of the side members 3, longitudinal fitting recesses 13 into which reinforcing ribs 28 (see FIG. 7) of the outer member 25 described below are fitted are formed at three locations (see FIG. 3). ).

  A transponder 14 is attached to the side member 3. As shown in FIG. 6, the transponder 14 includes a communication unit 17 having a coiled antenna wound around a ferrite core 16 in a glass tube 15, a transmission / reception circuit (corresponding to a control unit) 18, an IC memory, and the like. The storage unit 19 is accommodated. In the transponder 14, when the communication unit 17 receives the microwave carrying data, the data received through the transmission / reception circuit 18 is stored in the storage unit 19, or the stored data is transmitted through the transmission / reception circuit 18. It has come to be.

  In addition, a plurality of remaining amount detection sensors 22 for detecting the remaining amount of the long material 21 wound around the core tube 1 are juxtaposed in the radial direction on the side member 3, and a remaining amount detecting unit 38 described below is provided. (See FIG. 10). Each remaining amount detection sensor 22 includes a light emitting element and a light receiving element, and each time the long material 21 is rewound by a predetermined amount, the remaining amount of the long material 21 can be detected.

  The connecting beam 4 is a flat plate connecting the side members 3 on the inner diameter side, and the side members 3 arranged to face each other are positioned at a predetermined interval and fixed by adhesion, welding or the like. A first locking receiving portion 23 and a second locking receiving portion 24 are formed at both ends of the connection beam 4. The first locking receiving portion 23 has a rounded edge, and the second locking receiving portion 24 has a protrusion that bulges upward from the edge of the connection beam 4. An outer surface member 25 constituting an outer peripheral surface around which the long material 21 is wound is attached to the connection beam 4 (see FIG. 7). At both ends of the outer surface member 25, a substantially C-shaped first locking portion 26 and a second engagement that are respectively locked to the first locking receiving portion 23 and the second locking receiving portion 24 of the connection beam 4. The stop part 27 is protrudingly provided. Further, a total of three reinforcing ribs 28 project in the thickness direction at both edge portions of the outer surface member 25. Further, a holding portion 29 is provided on one end side of the outer surface member 25. As shown in FIG. 7, the holding portion 29 is rotatably attached to the outer surface member 25, and can hold the long material 21 between the outer surface member 25. Specifically, the projection 30 provided at the tip of the holding portion 29 is fitted into the fitting recess 31 formed in the outer surface member 25 through the long material 21 so that the long material 21 can be temporarily fixed. It has become.

  The core tube 1 having the above-described configuration is assembled as follows. First, the outer diameter member 2 is formed by connecting and integrating the connecting members 4 so that the side members 3 are juxtaposed at predetermined intervals. The number of the side members 3 and the connecting beams 4 is changed depending on the width of the long material 21 to be wound. When the width of the long material 21 is narrower than this, it is only necessary to connect the two side members 3, and when it is wide, it is sufficient to connect three or more.

  Next, the outer diameter members 2 are sequentially connected by fitting the shaft portion 6 to the bearing portion 9 to form a cylindrical shape. At this time, the outer member 25 is attached to the outer member 2 when the next outer member 2 is connected. Specifically, while the first locking portion 26 of the outer surface member 25 is locked to the first locking receiving portion 23 of the connecting beam 4, the second surface member 25 is rotated with respect to the outer diameter member 2 while rotating the outer surface member 25. The locking part 27 is locked to the second locking receiving part 24. As a result, the opposing side members 3 can be fixed not only by the connecting beam 4 but also by the outer member 25, and the overall rigidity is enhanced. Further, the outer surface member 25 holds the next connected outer diameter member 2 between the outer diameter member 2 and prevents the outer surface member 25 from falling off. When the outer diameter member 2 is connected in a cylindrical shape, the shaft portion 6 escapes and moves through the recessed portion 11 to reach the through hole 10a, so that the operation can be performed smoothly.

  In the core tube 1 assembled in this manner, one end portion of the long material 21 is brought into contact with the holding portion 29 so as to protrude from the outer peripheral surface of the core tube 1, and one end portion of the long material 21 is connected to the outer surface member. After fixing by pinching between 25 and the holding | maintenance part 29, the elongate material 21 is wound.

  The core tube 1 around which the long material 21 is wound is supplied to a long material processing device 33, for example, a medicine packaging device 34 and a medicine bag printing device 35, and the long material 21 is rewound to form a wrapping paper or medicine bag. used.

A portion 44 is provided.

  As shown in FIG. 10, the tension adjusting unit 37 includes a rotation shaft 45 on which the core tube 1 is mounted, a conveyance roller 46 that conveys the long material 21, and a sensor that detects the slackness of the long material 21 (see FIG. 10). Not shown). Usable sensors include, for example, sensors that are provided at predetermined intervals in the vertical direction and always detect whether or not the long material 21 is located in this range. The tension adjusting unit 37 controls the rotation of the rotary shaft 45 or the conveying roller 46 by the control unit 44 described below based on the slackness of the long material 21 detected by the sensor. It is adjusted so that a certain tension is applied.

  The packaging processing unit 36 folds the elongate material 21 in the longitudinal direction and seals at a predetermined interval in the heat seal unit, thereby sequentially opening only one direction. In this state, powder, tablets, etc. Each medicine is accommodated one by one, and the opening is sealed.

  The remaining amount detection unit 38 is for detecting the remaining amount of the long material 21 wound around the core tube 1 as described above, and as described above, the long material 21 wound around the core tube 1. A plurality of remaining amount detection sensors 22 provided at a predetermined interval in the radial direction of the outer diameter side, and can be sequentially detected from the remaining amount detection sensor 22 on the outer diameter side as the long material 21 is rewound.

  The printing unit 39 is for printing a drug name or the like on the long material 21.

  The error detection unit 40 includes a speed sensor that detects the rotation speed of the rotation shaft on which the core tube 1 is mounted, a temperature sensor that detects the temperature of the heat seal unit of the packaging processing unit 36, and whether or not the medicine has fallen appropriately. This includes a drug detection sensor that detects this. The speed sensor is used to detect an error as to whether or not there is a change that greatly exceeds the speed change assumed when the long material 21 is rewound. Further, the temperature sensor is used for error detection as to whether or not an abnormality has occurred in the heat seal portion with reference to the graph of FIG. 11 based on the detected data. As the drug detection sensor, for example, as shown in FIG. 12, a drug detection sensor 47 such as a photocoupler including a light emitting element 48a and a light receiving element 48b can be used, and the voltage between the emitter and the collector in the light receiving element 48b. It is possible to employ a configuration in which whether or not the value exceeds a preset threshold value is detected by the A / D converter 49 or the operational amplifier 50 (any one may be employed). When the medicine detection sensor 47 detects that the medicine has passed, the next medicine is supplied by driving the drive motor 52 via the drive circuit 51, and the medicine is appropriately used. Is used to detect whether an error has been supplied.

  The transmission unit 41 and the reception unit 42 are detected by the error detection unit 40 and the machine number, the remaining amount information of the long material 21 detected by the remaining amount detection unit 38, and the transponder 14 of the core tube 1. Send and receive data such as error information.

  The memory 43 stores data such as error messages, accumulated operating time, date and time, machine number, and is called out.

  The control unit 44 receives input signals from the remaining amount detection unit 38 and the error detection unit 40, sends control signals to the tension adjustment unit 37, the packaging processing unit 36, and the like, and from the transponder 14 via the reception unit 42. The machine number where the pipe 1 is mounted is read, and the corresponding data in the memory 43 is written into the transponder 14 of the core pipe 1 via the transmitter 41.

  As shown in FIG. 13, the medicine bag printing device 35 includes a tension adjustment unit 37, a remaining amount detection unit 38, a printing unit 39, an error detection unit 40, a transmission unit 41, a reception unit 42, and a memory 43, similar to the drug packaging device 34. And a control unit 44 and a medicine bag manufacturing unit 53 instead of the packaging processing unit 36. The medicine bag manufacturing unit 53 manufactures a medicine bag from the long material 21. The medicine bag is printed on the printing unit 39 by printing predetermined items such as a hospital name and a frame. Information determined based on prescriptions such as prescription days and precautionary notes is printed.

  The core tube 1 that has been used after the long material 21 has been rewound by the long material processing device 33 is stretched flat and laminated at a predetermined location as shown in FIG. And it collect | recovers regularly and the new elongate material 21 is wound in a paper winding factory. At this time, data is collected by the core tube collection processing device 32.

  As shown in FIG. 14, the core tube collection processing device 32 includes a data processing unit 54, a production plan processing unit 55, a control unit 57 having a maintenance processing unit 56, a transmission unit 58, a reception unit 59, and a memory 60. ing.

  The data processing unit 54, the production plan processing unit 55, and the maintenance processing unit 56 perform processing described later based on data read from the transponder 14 attached to the core tube 1. In the memory 60, error analysis data and date / time data can be written and recalled. The transmitting unit 58 and the receiving unit 59 are the same as those of the long material processing apparatus 33 described above.

  Next, the distribution process of the core tube 1 will be described with reference to the flowcharts of FIGS.

  The operations before and after supplying the core tube 1 around which the long material 21 is wound to the user side and the processing contents will be described with reference to the flowcharts of FIGS. 15 and 16. First, the long material 21 is wound around the core tube 1 (step S1), and the storage unit 19 of the transponder 14 stores the machine number to which the core tube 1 is attached and the shipping date and time of the core tube 1 (step S1). S2), supplied to the user (medical institution) and stored (step S3). If the core tube 1 is attached to the long material processing device 33 (step S4), the long material processing device 33 reads the machine number and the shipping date from the transponder 14 of the attached core tube 1, and conversely, The serial number and the use start date and time of the scale material processing device 33 are written (step S5).

  Here, whether or not an error has been detected (step S6), whether or not an emergency operation has been performed (step S7), whether or not the measurement set time has elapsed (step S8), and the remaining paper tension rank Are determined until the remaining amount of paper runs out (step S10).

  The error corresponds to a case where a signal is issued to the control unit 44 due to a mismatch of the machine numbers, a paper jam of the long material 21, a medicine drop failure, or the like by the error detection unit 40. Here, the error includes a case where the sensor malfunctions due to light from a fluorescent lamp or the like. If such an error occurs, the corresponding data and the date and time are stored in the storage unit 19 of the transponder 14 as described below (step S11).

  The emergency operation refers to an operation for making an emergency stop of the long material processing apparatus 33 when an incorrect prescription is made. This emergency stop is performed by pressing an emergency stop button provided on the long material processing apparatus 33. In this case, if there is an input of a signal indicating an emergency operation, the corresponding data and the date and time are stored in the storage unit 19 of the transponder 14 as in the case of the error detection described above (step S12).

  The measurement set time means a time period for reading the temperature of the packaging processing unit 36 detected by the temperature detection sensor and the rotation speed of the transport roller 46 detected by the speed detection sensor. In the present embodiment, the measurement setting time is set to 1 hour, for example, and every time 1 hour elapses, detection data from the remaining amount detection unit 38, the error detection unit 40, etc. is read (step S13). ) And the detected date and time are stored in the transponder 14 (step S14).

  The tension rank of the remaining amount of paper indicates the degree to which the tension acting on the long material 21 is maintained within a certain range, and the rotational speed of the core tube 1 and the length of the long material 21 wound around the core tube 1. It is determined by the relationship between the amount and the rotational speed of the first conveying roller 46 to which the long material 21 is supplied from the core tube 1. Therefore, in step S9, it is determined whether or not the tension ranks coincide with each other based on whether or not the long material 21 is located in this range by both sensors of the tension adjusting unit 37. If the tension ranks do not match, the tension rank is adjusted (step S15). The tension rank is adjusted by decreasing the rotational speed of the rotating shaft 45 on the core tube 1 side when the amount of bending of the long material 21 is large, and increasing the rotational speed of the core tube 1 when it is small (conveyance). This may be dealt with by adjusting the rotation speed of the roller 46 or adjusting the rotation speeds of both the rotation shaft 45 and the conveyance roller 46 on the core tube 1 side. When the tension rank is adjusted, the date and time of the adjustment is stored in the storage unit 19 of the transponder 14 (step S16).

  In this way, the predetermined processing is continued in the long material processing device 33 while writing each data to the transponder 14, but when the remaining amount of paper in the core tube 1 is exhausted (step S10), the core tube The end date and time is stored in one transponder 14 (step S17), and the core tube 1 is removed from the long material processing device 33, so that the core tube 1 is flattened and stored in a predetermined place (step S18). ). Then, the stored core tube 1 is recovered (step S19), and the stored data is read by the core tube recovery processing device 32 (step S20). Subsequently, the read data is classified by type (step S21), and the winding work time of the core tube 1 is reviewed as described below (step S22), or the maintenance time plan of the long material processing apparatus 33 is planned. Information processing such as standing up (step S23) is performed.

  Data is written from the long material processing device 33 to the transponder 14 in the distribution process of the core tube 1 according to the flowchart of FIG. However, if the data writing to the storage unit 19 fails due to a failure of the transponder 14 in the previous core tube 1, the long material processing apparatus 33 keeps the data accumulated.

  In this data writing process, it is first determined whether or not there is accumulated data (step S31). If there is no accumulated data, it is determined whether or not there is write data (step S32), and if there is accumulated data, the desired data cannot be collected depending on the previous core tube 1; The transponder 14 is awakened by emitting a microwave so that the accumulated data can be transmitted by the core tube 1 without determining whether or not there is (step S33). Here, the write data corresponds to a case where an error occurs in the long material processing apparatus 33 or an emergency operation is performed.

  Then, it is determined whether or not there is a response by emitting the microwave (step S34), and if there is a response, write information is transmitted (step S35). Here, in order to determine whether or not the information has been correctly written, by receiving the microwave from the transponder 14 (step S35), it is determined whether or not it matches the write data (step S38). . If they match, the process ends. If they do not match, the writing process is performed again, and the process is repeated until writing fails three times (step S37). When there is no response from the transponder 14 or when writing has failed three times in succession, it is determined that a problem such as a failure of the transponder 14 has occurred, and the data remains stored (step S39). ) As described above, the stored data is written in the next core tube 1.

  Next, a case where the core tube 1 is collected on the side of providing the core tube, a predetermined analysis is performed, the production plan of the long material 21 is planned, and the maintenance time of the long material processing apparatus 33 is planned will be described.

  (Production plan of long material) In general, the order quantity of the long material 21 has a significant change on a monthly basis as shown in the graph of FIG. The cause is also influenced by various factors such as the order period (the number of days from when an order is placed until the next order is placed) and the order quantity differ between medical institutions. Therefore, as shown in the graph of FIG. 19, it is expected that the order quantity will exceed the production quantity. In order to cope with this, the manufacturer must have extra inventory. In this case, problems such as occupied space occur. Therefore, in the present invention, the data collected from the core tube 1 and written in the transponder 14 is accumulated, and based on the accumulated data, the future usage amount in each medical institution is predicted as follows to produce the data. I plan to make a plan.

  That is, the production amount of the long material 21 is predicted according to the flowcharts of FIGS. 20 to 24 and used for production planning.

  First, it is determined whether or not there is accumulated data relating to a medical institution for which production is to be predicted (step S41). If there is no accumulated data relating to the medical institution for which the production amount is to be predicted, delivery data such as order results so far is read (step S44), and the usage amount per month is estimated (step S45). Next, it is determined whether there is accumulated data in another medical institution corresponding to the estimated month (step S46). If there is corresponding stored data, it is determined whether or not it is applicable in order from the closest usage amount (the predicted usage amount has been calculated or can be calculated) (step S47). Then, if applicable, the predicted usage amount that has already been calculated or newly calculated is read (step S48) and corrected based on the difference in the usage amount compared in step S46 until after three months. (Step S49). If there is no accumulated data, or if it is unsuitable for predicting usage, it is assumed that the monthly usage calculated based on delivery data will not change over the next three months. The amount of use up to three months later is predicted (step S50). At the same time, based on the collection data based on the other core tube 1, if the predicted usage is newly calculated as described below, this is also used. This is performed in all the processes described below.

  If there is accumulated data relating to a medical institution whose production volume is to be predicted, it is determined whether or not the accumulated data exceeds three months (step S42). Here, the reason for selecting March as a guideline for judgment is that it corresponds to the fact that orders from medical institutions are generally made in the cycle of March, and the season (in Japan, there are four seasons and changes in the cycle of March. This is to take into account the difference.

  If the accumulated data does not exceed March, first, the accumulated data is read (step S51), and the usage amount per month is determined (step S52). In this case, if the accumulated data is less than one month, the usage amount per month is calculated from the average usage amount per day. If the usage amount per month is determined in this way, the usage amount up to three months later is predicted in the same manner as in steps S46 to S49 (steps S53 to S56). The collected data indicates the actual usage amount of the long material 21 in each medical institution. Therefore, the prediction accuracy is high as compared with the case of predicting based on the delivery data described above. Further, when there is no accumulated data regarding other medical institutions, it is estimated that the determined usage amount per month does not change until March, and the usage amount until March is predicted (step S57). In this case, it is preferable to correct the usage amount based on a change trend of the usage amount on a daily or weekly basis. In other words, since it is possible to grasp the change trend of the actual usage amount in each medical institution, it is easy to predict the future usage trend.

  When the accumulated data regarding the medical institution for which the production amount is to be predicted exceeds March, it is further determined whether or not it exceeds one year (step S43).

  If the accumulated data exceeds March but is within one year, it is determined that it is possible to read the change in the usage amount of the long material 21 over at least two seasons. Therefore, this accumulated data is read (step S58), and the usage amount until after three months is predicted as follows. That is, it is determined whether or not there is comparable accumulated data in which the difference in usage amount of each month is within a certain range among accumulated data related to other medical institutions (step S59). If there is such other accumulated data, it is determined whether or not the accumulated data is applicable (predicted usage has been calculated or can be calculated) (step S60). Reading (step S61), for example, applying a correction according to the average value of the difference in usage amount (step S62). In this case, accumulated data having the same usage tendency may be used in which the change rate of the usage amount in each month is within a certain range. Further, when there is no such other accumulated data or when it is not applicable, the usage amount is predicted based only on the accumulated data (step S63). As described above, the accumulated data extends over at least two seasons. Therefore, the increase or decrease in the number of patients due to the influence can be taken into consideration. For example, if the usage amount tends to increase at the beginning of a certain season, it may be predicted that the usage amount is increasing during that season.

  When the accumulated data regarding the medical institution for which the production amount is to be predicted exceeds one year, it is determined that the data indicating the usage amount of the long material 21 is accumulated at the same time at least one year ago. Therefore, based on the usage in the same month one year ago, the usage up to three months later is predicted as follows. That is, the stored data is read (step S64), and it is determined whether or not the change in the amount of use compared to the corresponding month of the previous year exceeds a certain range (step S65). The amount of use up to three months later is applied (step S66). If the change in the usage amount is large, the data stored in another medical institution is read (step S67), and the usage amount is corrected with reference to the change in the usage amount (step S68). That is, if the same tendency is seen in other medical institutions, it is determined that there is a special situation. For example, when a cold is prevalent, the usage amount of the long material 21 is estimated to increase during the winter, and the predicted usage amount is corrected upward. However, if the trend is specific to the medical institution, it will be ignored in this forecast. Of course, if this trend continues next time, the predicted usage is corrected. When there is accumulated data for two years or more, the usage amount is predicted by grasping the change trend of the usage amount in the same month of each year. Thereby, prediction with higher accuracy is possible.

  The amount of use obtained as described above is predicted based on accumulated data indicating the actual usage status of the long material 21 in each medical institution, unlike the method performed only by conventional delivery data. Is. Therefore, the difference between the predicted usage amount and the actual usage amount increases as the accumulated data increases, and the prediction accuracy increases.

  Next, a production plan is made by performing production aggregation based on the predicted usage until March.

  That is, it is determined whether or not the predicted usage amount for each month until March is greater than the normal production amount for each month (step S69). If there is no month in which the predicted usage exceeds the normal production, the production up to one month later is determined as the predicted usage (step S70). If there is a month when the predicted usage exceeds the normal production, production is advanced (step S71). As a result, it is possible to prevent a problem that production is not in time, and to perform stable production by eliminating variations in the production amount of each month.

  Here, when the predicted usage amount after one month exceeds the normal production amount, the production amount is adjusted as follows. For example, since the stock quantity is known for each medical institution, the production of the medical institution that is not used up for at least one month from the predicted usage is postponed and turned to the next month. If it is not possible to cope with the adjustment of the production amount in this way, the production amount up to one month later is corrected to be larger than usual so that the delivery can be made in time.

  In this way, production is performed based on the production plan up to one month later. This production plan is reviewed every month. The reason for reviewing the production plan every month is that the accumulated data of each medical institution surely increases after one month, so that the long material 21 in each medical institution is more accurately taken in. This is to predict the amount of usage and plan production.

  Further, if the accumulated data increases and the error with the actual usage amount decreases, the prediction period may be further extended from March. As a result, it is possible to eliminate a variation in production volume every month and to establish a stable production system.

  In addition, if the number of deliveries is entrusted by a medical institution, the quantity and timing of the next delivery can be easily predicted, so if an order exceeding the production volume is predicted, the quantity delivered on the immediate delivery date It is also possible to cope with this by reducing.

  (Maintenance Time Plan) On the other hand, the maintenance time of the long material processing device 33 is planned as follows by the core tube recovery processing device 32 according to the flowchart of FIG.

  That is, first, it is determined whether or not the error information corresponds to an urgent item (step S81). More specifically, if the detected temperature in the packaging processing unit 36 is abnormally high, such as an item requiring urgency, it is determined whether or not the risk is high (step S82). If the risk information is high, such as the possibility of a fire, the user is notified of the use stop by telephone or the like, and a worker is dispatched immediately to perform maintenance work (step S83). On the other hand, if the risk information is low, a worker is dispatched on the same day before the user's work is disturbed (step S84).

  On the other hand, if the item does not correspond to an urgent item, it is determined whether or not the error information has increased by 20% from the previous time (step S85). If the error information has increased by more than 20%, it is determined whether or not the influence on the performance of the long material processing apparatus 33 is large (step S86). If the error information is large, the same processing as in step S44 is performed. If it is smaller, a worker will be dispatched in the near future (step S87).

  If the increase amount of the error information is less than 20% than the previous time, it is determined whether or not the error information has decreased (step S88). If the error information increases, it is determined that the increase amount is 0 to 20%. Therefore, it is determined whether or not the increased error has an effect on workability (step S99). For example, the same processing as in step S44 is performed, and if there is no influence, a worker is dispatched during the week (step S90).

  If there is no error information or if the error information has decreased, it is determined whether or not maintenance has been performed for a long time (step S91). If the maintenance is not performed for a long period of time, the same processing as the step S87 is performed.

  Further, it is determined whether or not maintenance has been performed recently (step S92). If the maintenance has just been performed, the state is observed until the next collection of the core tube 1 (step S93). On the other hand, if the maintenance time is not recent, it is determined whether the error information includes an element of interest (step S94). Here, the element to be worried about refers to a phenomenon such as when the collected data such as the heater temperature and the packaging speed, which is monitoring information, is measured higher or lower than the standard. If there is an element to be worried about, the same processing as step S90 is carried out.

  In the above embodiment, the remaining amount of the long material 21 is detected by the remaining amount detection sensor 22, but a rotation roller with an encoder is provided on the conveying line of the long material 21 for detection.
