Description

  The present invention relates to a contaminated clothing sorting apparatus, and more particularly to a technique for sorting non-contaminated clothing and contaminated clothing before or after washing.

  In radioactive material handling facilities such as nuclear power plants and nuclear fuel treatment facilities, it is necessary to confirm the presence or absence of radioactive contamination on clothing worn by workers (coveralls, underwear, hats, socks, etc.). The confirmation is generally performed using a clothing monitor or a laundry monitor. Such a measurement may be performed after the garment is washed and dried, or may be performed before the garment is washed. A sorting mechanism is provided after the clothing monitor. When radioactive contamination (for example, residual contamination after washing) is found in the clothing monitor, the sorted clothing collects the contaminated clothing separately and sorts it into, for example, a contaminated clothing container. Stored. After sorting, the non-contaminated garment is sent to, for example, a folding device if it is a garment after washing and drying. If it is clothing before washing, it is sent to the washing device.

  A conventional sorting apparatus has, for example, the configuration shown in FIG. The clothing measured by the clothing monitor 10 and discharged by the transport mechanism is transferred to the movable conveyor 14 in the sorting device and transported to the next device 16. However, when the clothes monitor 10 determines that the clothes are contaminated clothes, the conveyor drive mechanism 18 operates, the inclination angle of the conveyor 14 is increased, and at the same time, the reverse conveyance operation of the conveyor 14 is executed. Thereby, the contaminated clothing on the conveyor 14 or the contaminated clothing that is moving to the conveyor 14 is put into the contaminated clothing box 20 installed below. Patent Documents 1 and 2 disclose other sorting mechanisms.

Japanese Patent Laid-Open No. 11-2111835 Japanese Patent Laid-Open No. 10-20041

  In the conventional sorting mechanism shown in FIG. 5, when contaminated clothing is put into the contaminated clothing box, uncontaminated clothing may be entered together with the contaminated clothing. That is, in the configuration shown in FIG. 5, regardless of the type of clothes and the contamination position on the clothes, the conveyor is inclined at the same time as the detection of the contamination, and the reverse operation is performed. Even non-contaminating clothing that flows through tends to fall together. Contaminated clothing must be reliably sorted. As a result, priority is given to the fact that uncollected clothing may be miscollected to some extent, but it is also necessary to reduce the possibility of such miscollection. . The distance between the clothes is, for example, 30 cm. However, if the distance is increased, the processing efficiency is lowered. Therefore, it is not desirable to increase the distance between the clothes too much. Processing efficiency is also lowered when clothes are not thrown in when contamination is detected, or when clothing transportation in the clothing monitor is stopped.

  It can be pointed out that the mechanism described in Patent Document 1 may cause the same problem as described above. The device described in Patent Document 2 uses a hanger to convey clothes and may be sorted in units of hangers, but there are other problems such as the complexity of setting clothes on hangers and contamination of hangers. Is concerned.

  It is an object of the present invention to prevent or reduce the likelihood that uncontaminated clothing will be sorted along with contaminated clothing.

  The present invention relates to a contaminated clothing sorting device provided at a subsequent stage of a clothing measuring device for measuring radioactive contamination of clothing, a first conveyor for transporting the clothing after measurement by the clothing measuring device, and a discharge end of the first conveyor A garment that has fallen from the section is mounted, a second conveyor that conveys the garment that is mounted, and a mechanism that is provided corresponding to a dropping path between the first conveyor and the second conveyor, Non-contaminated clothing determined to be free of contamination by the clothing measuring device is dropped onto the second conveyor, and contaminated clothing is determined to be contaminated by the clothing measuring device without falling onto the second conveyor. And a sorting mechanism having a drop guide member that drops onto a part and a drive mechanism that changes the posture of the drop guide member, the drop guide member having the non-contaminated clothing in front When falling from the discharge end of the first conveyor, the first posture is to drop the non-contaminated clothing onto the second conveyor, and when the contaminated clothing falls from the discharge end of the first conveyor, The second posture is such that the non-contaminated clothing is dropped onto the contaminated clothing storage unit without being dropped onto the second conveyor.

  According to the above configuration, the contaminated clothing is separated from the non-contaminated clothing in the contaminated clothing sorting device provided at the subsequent stage of the clothing measuring device. The contaminated clothing sorting apparatus includes a first conveyor and a second conveyor, and further includes a sorting mechanism that functions between them. The sorting mechanism has a function of distributing the contaminated clothing to the contaminated clothing accommodating portion instead of the second conveyor in the transfer process using the drop when actually transferring the clothing from the first conveyor to the second conveyor. The sorting mechanism has a drop guide member, which is driven by a drive mechanism. The drop guide member is normally in the first posture, in which case the dropped non-contaminated clothing is placed on the second conveyor. The fall guide member is in the second posture when the contaminated clothing falls, and the dropped contaminated clothing is collected into the contaminated clothing storage unit. The drop guide member desirably exhibits the action of guiding the fallen object in the second posture, but may be one that exhibits the guide action of the fallen object in the first posture or in both postures. The contaminated clothing container may be a member that receives the contaminated clothing, and may be a simple box or a device that transports the received contaminated clothing.

  According to the above configuration, it is not necessary to stop the conveyor or reversely rotate for sorting, so that the problem of collecting non-contaminated clothing can be solved or reduced. Since it is a simple sorting method in which clothing is dropped and the posture of the drop guide member is variable, the configuration of the sorting device can be simplified and the operational reliability can be improved. When contaminated clothing occurs, basically it is not necessary to stop the clothing measuring device or the first and second conveyors, and they can be operated as they are at a constant speed. Can be simplified.

  In order to reliably perform the sorting operation, an identifier (or management number) is assigned to each garment input to the clothing measuring device, and the measurement result of each clothing is managed in association with each identifier. After identifying or identifying the garment that is the object of transportation, it is possible to reliably recognize whether the garment is non-contaminated clothing or contaminated clothing, and then control the posture of the drop guide member. desirable. For example, there is provided a means for giving a serial number to each piece of clothing put into the clothing measuring device and a means for giving a serial number to each piece of clothing to be transported in the sorting device. May be identified and the presence or absence of contamination may be recognized for each piece of clothing. When such a means is mounted, it is desirable to provide a sensor for detecting clothes on the conveyance path in each apparatus.

  Preferably, the first posture is a posture in a state where the drop guide member is retracted from the drop route, and the second posture is a posture in a state where the drop guide member is advanced so as to cross the drop route. is there. According to this configuration, when the drop guide member is in the second posture, it functions as a shooter. In addition, you may comprise so that a fall guide member may contact only contaminated clothing. When rotating the drop guide member, it is desirable to make the center of the rotation axis coincide with the rotation axis on the discharge end side of the first conveyor. In other words, if the drop guide member is rotated along the movement trajectory of the clothing that is going to fall around the discharge end, it is easy to maintain a constant distance from the discharge end, It is easy to move the drop guide member across the drop path.

  Preferably, the drop guide member includes a curved portion having a curved shape surrounding the discharge end portion while forming a gap with the discharge end portion of the first conveyor, and a flap hanging from the curved portion. And a portion. The curved portion functions as a receiving guide portion, and the flap portion functions as a slide or a shooter.

  Preferably, the receiving end of the second conveyor is installed at a position entering the lower side of the discharging end of the first conveyor, and in the second posture, the flap portion obliquely crosses the dropping path. And the leading edge of the flap portion enters a position further entering the lower side of the first conveyor than the receiving end portion of the second conveyor, and the contaminated clothing slides on the surface of the flap portion. Guided to the contaminated clothing container. According to this configuration, in the second posture, since the leading edge of the flap portion is further intruded than the receiving end of the second conveyor, the contaminated clothing can be reliably guided to the contaminated clothing containing portion, and at the same time, the contamination The contact of clothing with the second conveyor can be prevented or the possibility thereof can be reduced.

  Preferably, the drive unit is configured such that before the contaminated clothing falls from the discharge end of the first conveyor and after the non-contaminated clothing before the contaminated clothing falls from the discharge end of the first conveyor. The drop guide member is changed from the first posture to the second posture at the operation timing. That is, the posture change of the drop guide member is executed at the timing between clothes transport. If the contaminated clothing is continuously generated, the second posture may be maintained as it is until the final sorting of the contaminated clothing is completed after the fall guide member is placed in the second posture. Each time the contaminated clothing falls, the posture may be returned to the original shape.

  Desirably, at least one of a posture change timing from the first posture to the second posture and a posture return timing from the second posture to the first posture is determined by the conveyance speed of the first conveyor, the clothing type, It has a control part which controls based on at least one of a cloth conveyance interval and a contamination site on clothes. Timings that are the basis for calculating posture change timing and posture return timing include clothing input timing, measurement completion timing, discharge timing, etc. for clothing measuring devices, and clothing receiving timing, transport path for sorting devices. Examples include clothing passage timing at a predetermined position above, clothing arrival timing at the discharge end, and the like. It is desirable to provide a sensor for detecting the passage of clothing at a necessary location.

  The present invention relates to a clothing measuring system including a clothing measuring device for measuring radioactive contamination of clothing and a contaminated clothing sorting device provided at a subsequent stage thereof, wherein the clothing measuring device transports the input clothing. And measuring means for measuring radiation from the clothes being conveyed by the conveying means, the contaminated clothing sorting device comprising: a first conveyor for conveying the clothes after measurement by the clothing measuring device; A garment dropped from the delivery end of one conveyor is mounted, a second conveyor for transporting the mounted garment, and a mechanism provided corresponding to a dropping path between the first conveyor and the second conveyor A non-contaminated garment determined to be free of contamination by the garment measuring unit is dropped on the second conveyor, and a contaminated garment is determined to be contaminated by the clothing measuring device. And a sorting mechanism having a drop guide member that drops into the contaminated clothing container without dropping onto the second conveyor, wherein the drop guide member drops the non-contaminated clothing from the discharge end of the first conveyor. The first posture of dropping the non-contaminated clothing onto the second conveyor, and when the contaminated clothing falls from the discharge end of the first conveyor, the non-contaminated clothing is removed from the second conveyor. It becomes the 2nd attitude | position which makes it fall to a contaminated clothing accommodating part, without dropping on a conveyor, It is characterized by the above-mentioned.

  Preferably, the garment input into the garment measuring apparatus is a garment before or after washing, and the garment includes a plurality of types of cloth products having different sizes, and the sorting mechanism is configured based on the type of the garment. A control unit for controlling the operation timing is provided. Since the length in the transport direction varies depending on the type of clothing, it is desirable to consider the type of clothing in order to appropriately set the operation timing for the drop guide member.

  As described above, according to the present invention, it is possible to prevent or reduce the possibility of non-contaminated clothing being sorted together with contaminated clothing.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

  FIG. 1 shows a preferred embodiment of a laundry system according to this embodiment. In the present embodiment, this laundry system includes a clothing monitor 30 and a sorting device 32. The laundry system shown in FIG. 1 is installed in, for example, a nuclear power plant, a nuclear fuel processing facility, etc., and the target clothing includes work clothes, underwear, hats, socks, Such as gloves. Clothing that has been washed and dried may be targeted, or clothing before washing may be targeted.

  The clothing monitor 30 functions as a laundry monitor, a clothing measuring device, or the like. A sorting device 32 is provided at the rear stage of the clothing monitor 30. The sorting device 32 is a device that sorts non-contaminated clothing and contaminated clothing. For example, a folding device is provided at the subsequent stage of the sorting device 32. Below, each apparatus is explained in full detail.

  The clothing monitor 30 includes a lower transport mechanism 34, an upper transport mechanism 36, a lower detection unit 38, an upper detection unit 40, a controller 42, and an input device 44. The lower conveyance mechanism 34 and the upper conveyance mechanism 36 function as conveyance means in combination, and convey clothes put by an operator at a constant speed. During the conveyance process, the presence or absence of radioactive material contamination is measured on the clothing. The clothing after the measurement appears at the discharge end of the conveyance path. Clothing is transferred from the discharge end to the next sorting device 32.

  The lower transport mechanism 34 includes a transport belt 46 and two rollers 48 and 50. In the present embodiment, the conveyor belt 46 is constituted by a wire mesh. This is for durability and prevention of static electricity. The wire mesh is stretched around two rollers 48 and 50. The upper transport mechanism 36 includes a transport belt 52 and four rollers 54-60. The conveyor belt 52 is also composed of a wire mesh, and is stretched around four rollers 54-60. The driving directions of the conveyor belts 46 and 52 are as shown in the figure.

  As described above, the two detection units 38 and 40 are provided at the center of the clothing monitor 30. Since they basically have the same configuration, the structure of the lower detection unit 38 will be described as a representative. The lower detection unit 38 includes a shielding member 62, a scintillator plate 64 provided therein, four photomultiplier tubes (PMT) 66 for detecting light generated there, and the like. The scintillator plate 64 is divided as necessary, so that it is possible to determine the presence / absence of contamination in the four areas on the left and right sides and the front and rear sides in the conveyance direction. Of course, the distinction may be made only on the left and right or only on the front and back. Unlike the upper detection unit 40, the lower detection unit 38 has a protection member 68. This is a member that protects the surface of the scintillator plate 64 from contamination.

  A sensor 70 is provided on the inlet side in the transport path. The sensor 70 detects the garment that has been thrown in. The sensor 70 determines that the garment has reached the position where the sensor 70 is disposed, and detects the length of the garment in the transport direction. In this embodiment, the sensor 70 includes a light emitter 70a and a light receiver 70b. That is, by forming a light beam between them, clothing can be detected by the light beam. Of course, as the sensing method, a magnetic sensor or a contact sensor can be used in addition to the optical one.

  In this embodiment, the input device 44 is constituted by a liquid crystal panel with a touch sensor. The operator inputs the type of clothes to be thrown in using the input device 44. Usually, since the same type of clothing is continuously input, if the setting is performed at the start time, it is not necessary to input the type every time each clothing is input. Of course, each input of clothing may be input. The controller 42 controls the operation of each component included in the clothing monitor 30. In this embodiment, the controller 42 also has a function as a system controller, that is, the controller 42 also performs operation control of the sorting device 32 described later.

  Next, the sorting device 32 will be described. In this embodiment, the sorting apparatus 32 includes a first conveyor 72, a second conveyor 74, a sorting mechanism 76, and a contaminated clothing storage box 78. As described above, the sorting device 32 sorts contaminated clothing and non-contaminated clothing based on the measurement result of the clothing monitor 30. The configuration will be specifically described below.

  The first conveyor 72 has a transport belt 80 and two rollers 82 and 84. The conveyor belt 80 is stretched between two rollers 82 and 84, and the clothes are conveyed from the receiving end to the discharge end of the conveyor belt 80. In FIG. 1, the clothing passed from the clothing monitor 30 to the sorting device 32 is represented by reference numeral 86, and the clothing being conveyed by the first conveyor 72 is represented by reference numeral 88.

  The sensor 90 is a sensor that detects clothing, and is provided at a predetermined position on the first conveyor 72. That is, clothing passing through the position is detected. In this embodiment, the sensor 90 includes a light emitter 90a and a light receiver 90b, and a light beam is formed between them. As will be described later, a serial number as a management number is given to each garment at a detection timing by a sensor 70 provided on the garment monitor 30. On the other hand, each detection timing of the sensor 90 in the sorting device 32 A similar serial number is given to clothing. Thereby, identification can be performed between the clothing flowing through the clothing monitor 30 and the clothing flowing through the sorting device 32. In the clothing monitor 30, the presence or absence of contamination is managed and recorded in association with each serial number. In the sorting device 32, the serial number is compared with the recorded result, and the clothing of interest is noticed. The presence or absence of contamination can be easily recognized. However, in this embodiment, such authorization and determination are performed by the controller 42.

  The second conveyor 74 has a conveyor belt 104 and a pair of rollers 106 and 108. The conveyor belt 104 is stretched around a pair of rollers 106 and 108, and in the second conveyor 74, the clothes placed on the receiving end are sent out to the discharge end. As described above, a folding device or the like is provided at the subsequent stage of the second conveyor 74.

In more detail, between the first conveyor 72 and the second conveyor 74, a drop guide member 94 is provided at a position corresponding to a drop path (more precisely, a free fall path as shown) 92 described below. Is provided. The drop guide member 94 constitutes a main part of the sorting mechanism 76. Specifically, the sorting mechanism 76 includes a drop guide member 94 and a drive mechanism 96 that drives the drop guide member 94. As will be described later with reference to FIG. 3, the drop guide member 94 performs a rotational motion around the rotation axis of the roller 84. In the drawing, the drop guide member 94 is in the first posture, that is, in the retracted posture. A guide member is shown, and reference numeral 94A shows a drop guide member in a rotating state (forward movement state), that is, in the second posture. In the second posture, the drop guide member crosses the drop path 92.

The positional relationship of each component will be described in more detail. The edge of the receiving end of the second conveyor 74 enters the lower side of the first conveyor 72 with reference to the edge of the discharge end, that is, the upper end of the first conveyor 72. That is, the clothes that fall freely through the dropping path 92 are surely received by the second conveyor 74. On the other hand, in the drop guide member in the second posture shown by the reference numeral 94A, it rotates until it covers the upper end of the receiving end of the second conveyor 74, and its lower edge, that is, the edge 94B is the second edge. It is set to a position (a position on the left side in FIG. 1) further deeper than the edge of the conveyor 74 on the receiving end side. As a result, as will be described later, a contaminated clothing drop guide path 98 is formed as a path that goes further into the receiving end of the second conveyor 74. According to such a configuration, the drop guide member 94 is in the second posture, whereby the falling clothing is guided by the drop guide member 94 and collected into the contaminated clothing storage box 78 below, and in the process It is possible to prevent contaminated clothing from coming into contact with the second conveyor 74.

  As will be described later with reference to FIG. 3, the drop guide member 94 includes a curved portion 94 a that is curved along the form of the carry-out end portion of the first conveyor 72, and a flap portion 94 b that is a hanging portion connected to the curved portion 94 a. It is configured. The lateral width is set to be at least larger than the lateral width of the conveyor belt 80, and the drop guide member 94 can be easily formed by curving a flat plate-like member. The curved portion 94a is curved while being separated from the transport end portion of the first conveyor 72 by a certain distance, and a passage for clothing is formed between them.

When the drop guide member 94 is in the second posture, the falling contaminated clothing falls along a route (contaminated clothing drop guide route) indicated by reference numeral 98 and finally falls into the contaminated clothing storage box 78. . A sensor 100 is provided in the middle of the drop path 98.

  FIG. 2 shows an example of the sensor 100. The sensor 100 includes a light emitting unit 100a and a light receiving unit 100b that are arranged above the box 78 and spaced apart on the left and right sides. A plurality of parallel light beams 102 are formed between the units 100a and 100b, that is, it is optically detected that a falling object has crossed the light beams 102. According to this configuration, it can be confirmed that the contaminated clothing is contained in the box 78.

  FIG. 3 shows a specific example of the sorting mechanism 76 shown in FIG. The sorting mechanism 76 is constituted by the drive mechanism 96 and the drop guide member 94 as described above. The drop guide member 94 includes a curved portion 94a and a flap portion 94b connected to the curved portion 94a. The drop guide member 94 rotates about the rotation shaft 110, and the rotation shaft 110 coincides with the rotation shaft of one roller in the first conveyor 72. Of course, it is also possible to set the rotation axes separately without matching them. A drop guide member 94 is attached to the rotating shaft 110 via arm members 112 and 114. A motor 116 is connected to the rotating shaft 110 via a gear mechanism 118. They constitute a drive mechanism 96. If the rotating shaft of the roller and the rotating shaft of the drop guide member 94 are made to coincide, the gap path formed between the discharge end portion of the first conveyor 72 and the curved portion 94a is made constant regardless of the rotational motion. It is possible to change the posture smoothly. Moreover, according to such a structure, it is possible to cross the flap part 94b naturally with respect to a fall path | route.

  In the present embodiment, the drop guide member 94 is changed to the first posture or the second posture by rotational movement, but the posture may be changed by linear movement. As an example of the posture change due to the linear motion, the second guide is provided by disposing the member 94 at a position not intersecting with the dropping path 92 when passing the non-contaminated clothing with the dropping guide member 94 in the state shown by the reference numeral 94A. The second posture in which the clothing is dropped onto 74, and when the contaminated clothing passes, the member 94 is slid and moved to a position crossing the dropping path 92 to drop the clothing into the contaminated clothing containing box 78. The method to do is mentioned. Moreover, you may make it change the attitude | position of the fall guide member 94 with the combination of the rotational motion and linear motion which were mentioned above.

  Returning to FIG. 1, in the present embodiment, the lower transport mechanism 34 and the upper transport mechanism 36 in the clothing monitor 30 are driven at a constant speed, that is, the conveyed product moves on the transport path at a constant speed. On the other hand, the first conveyor 72 and the second conveyor 74 in the sorting device 32 are also driven at a constant speed. Even if it is determined that the clothing monitor 30 is contaminated clothing and the sorting mechanism 76 operates in response to this, the operations of the conveyors 72 and 74 are not stopped and the conveying operation is continued as it is. However, the contaminated clothing to be dropped is sorted from the non-contaminated clothing by the posture change of the drop guide member 94.

  FIG. 4 shows an operation example of the system shown in FIG. S100 represents a size input process using the input device 44 shown in FIG. Of course, if the size has already been set, there is no need to perform an input operation again. S101 in FIG. 4 represents the detection of clothing by the sensor 70 shown in FIG. 1 and the assignment of a management number at the time of detection. The management number is a serial number that is counted up as described above. Of course, as long as a unique ID is assigned to each garment, various methods can be adopted.

  S102 shows the length confirmation process based on the detection signal of the sensor 70 shown in FIG. That is, the light shielding time varies depending on the length of the clothes in the conveying direction, that is, the passage time there is equivalent to the length of each piece of clothing. Can be confirmed. If the calculated length does not match the input size, error processing is executed in S102, for example, the operation of the system is stopped, or a notification to that effect is given to the user.

  S103 in FIG. 4 shows the radiation measurement process in the clothing monitor 30 shown in FIG. That is, the presence or absence of contamination is determined for each garment. In this case, it is desirable to make a determination up to the site of contamination. The determination result is recorded. In this case, the determination result is recorded in association with the management number assigned to each garment.

  S104 in FIG. 4 represents detection of clothing by the sensor 90 shown in FIG. A new management number is given by the detection. However, the management number is a serial number as described above. That is, in both the clothing monitor 30 and the sorting device 32, it is possible to attach each clothing to each other by numbering sequentially from the top clothing.

  In S105 in FIG. 4, the presence or absence of contamination of the clothing is recognized by referring to the measurement result database based on the management number of the clothing detected in S104.

  In S106 in FIG. 4, the attitude of the drop guide member is determined. Specifically, when the clothing detected by the sensor 90 shown in FIG. 1 is recognized as contaminated clothing, the posture of the drop guide member 94 is calculated with the operation timing calculated based on the detection timing by the sensor 90. Is changed, that is, the rotational motion from the first posture to the second posture is executed. In determining the operation timing, the conveyance speed of the first conveyor 72 and the interval between clothes are taken into consideration, and the arrangement position of the sensor 90 is further taken into consideration. In addition, the length of the clothing recognized as described above, the location of the contaminated site, and the like may be considered as necessary. In any case, the drop guide member 94 is driven to rotate after the previous drop of clothes has been completed and before the contaminated clothes have dropped, that is, at the timing between clothes.

  In S107 in FIG. 4, the contaminated clothing is confirmed to be dropped by the sensor 100 shown in FIG. 1, that is, the collection is confirmed. Immediately thereafter, the posture of the drop guide member 94 is returned to its original shape. However, when contaminated clothing continues, the second posture may be maintained without returning the drop guide member to the first posture.

  In FIG. 4, the process for uncontaminated garments is indicated by reference numeral 120 and the process for contaminated garments is indicated by reference numeral 122. In the case of non-contaminated clothing, the process of S100 to S105 described above is performed as indicated by reference numeral 120, and then the non-contaminated clothing is transferred onto the second conveyor without undergoing a special operation by the sorting mechanism. On the other hand, as indicated by reference numeral 122, in the case of contaminated clothing, after S100 to S105 are executed, sorting by the drop guide member is executed in S106, and further, the collection of contaminated clothing is confirmed in S107. The posture of the drop guide member is returned to the original shape. In any case, it is possible to continue the operation of the entire system as it is, thereby increasing the processing amount per unit time, or solving the inefficiency problem associated with the system stop in the past. There is an advantage.
