JP 2006-321590 A

  In the process of picking the correct quantity of multiple parts, materials, tools, products, etc., in the correct order, at the right time, in the process of picking the correct quantity, as a system for picking while detecting the picking operation of the worker, a handy barcode scanner, There is a system that performs picking while reading a barcode or an RF tag with a handy RFID reader or the like. In this case, the hand of the picking operator is blocked by a handy barcode scanner or a handy RFID reader, and there is a problem that two different operations of picking and reading cannot be performed simultaneously.

  In addition, there is a system that performs picking while confirming a picking operation when an operator's hand or the like reacts to the sensor with an area sensor. However, in the sensor system, the sensor reacts with any hand, and the worker cannot be specified. Establishing a method to improve the traceability of picking work by identifying the worker, analyzing the past picking work history of the worker, creating an optimal picking program for each worker, and creating a picking work history for each worker could not.

  In non-contact detection technology using a fixed detection device, it is necessary to move and read a detectable element attached to the operator's hand to the set position of the fixed detection device, which makes the picking operation unnatural. There is a problem that the working time becomes long. In addition, it is necessary to install as many fixed detection devices as the number of objects to be picked, and there is a problem that costs increase.

  In addition, in a picking system in which wiring is performed on the work shelf, the picking location is indicated by a lamp, and the completion of the picking work is transmitted to the computer via a button, switch, etc., the object storage to be picked, etc. It is necessary to provide a lamp, a display, a button, and a switch for each object storage of the picking work shelf, and the wiring construction cost is included, resulting in an increase in cost. Moreover, when the layout of the picking work shelf is changed due to increase or decrease of the object storage, rewiring of these lamps and the like is necessary, and there is a problem that there is no operational flexibility.

  In addition, in the case of a system that uses a work shelf that is fixed, there is a problem that the space of the work shelf becomes large and the movement distance of the worker during picking work becomes long.

  Further, in the case of a system that arranges a target object storage unit specific to a work shelf number, there is a problem that it takes time to rearrange the target object storage unit when switching models.

  Also, if you pick too many objects during picking work, the action of returning the extra number to the object storage, or picking again due to loss, etc. will be related to the picking operation and the number of objects in the object storage. There was a problem that it was difficult to put on.

Therefore, the present invention uses a portable detection device that can be attached to a part of the body such as an operator's hand, and devise a method for attaching a detectable element, thereby picking an object to be picked, or In order to solve the above-described conventional problems, a series of picking operations can be detected in the middle of a natural operation without stopping in the middle.
In addition, it eliminates human error of workers, speeds up work, records work history for each worker, and picking work while recognizing workers individually when multiple workers pick on one work shelf. Real-time inventory management is possible. Regardless of the shelf number on the work shelf, the picking program can be automatically converted according to the placement, and the smallest object storage on the work shelf. A picking system that can be placed in a space-saving work shelf, can manage inventory in real time, can share process information with RF tags etc. before and after the picking work, and can establish total traceability It is also intended to provide.

  In order to achieve the above object, a picking system of the present invention is a system for detecting an operator's picking motion in a process of picking a plurality of parts, members, tools, products, etc. The attached portable detection device picks up the object to be picked or the object storage in the state of picking the object to be picked, or in the middle of a natural operation without stopping a series of picking operations. It has a means for detecting a detectable element attached to a picking work shelf to be arranged and wirelessly transmitting the detected information to a computer.

  According to the picking system of the present invention configured as described above, it is confirmed that the portable detection device has reached the target object storage to be picked by detecting the detectable element. Is done. Accordingly, it is possible to detect a state in which the object to be picked is picked or in the middle of a natural operation without stopping a series of picking operations.

  And since the confirmation of picking is transmitted to the computer wirelessly from the portable detection device, there is no need to provide a detection switch or the like in each object storage, and as a result, a detection switch or the like for each object storage Wiring is not required.

  In the present invention, preferably, the laser light source or the LED light that can be collimated is further provided, and the irradiation direction of the laser light source or the LED light that can be collimated is the object storage to be picked and the work place after picking. Are sequentially controlled by the computer.

  In this way, the object storage to be picked and the work place after picking are sequentially irradiated by the parallel light from the LED light or the like, so that the object storage to be picked as in the prior art is displayed. There is no need to provide a lamp or indicator for each object storage in the picking work shelf. For this reason, the wiring for the lamp | ramp and indicator for every target object storage is unnecessary. As a result, the hardware cost of a large number of lamps according to the number of object storages can be reduced, and the wiring construction cost for lighting these lamps becomes unnecessary. Further, when the layout of the picking work shelf is changed due to increase / decrease of the object storage, these lamps and the like need not be rewired, and operational flexibility is ensured.

  Also preferably in the present invention, RFID technology is used for the detection device, the detection device comprises at least one antenna, and the detectable element comprises at least one RF tag.

  Thus, using the wearable RFID reader / writer attached to the operator's hand, the RF tag work shelf or object storage can be detected so that the picking operation can be detected without stopping the operator's natural picking operation. The place and method of mounting are devised.

  Preferably, in the present invention, means for movably attaching the detectable element to an object storage to be picked or an attachment attached to a picking work shelf, and a portable detection device attached to an operator's hand work. Means for detecting the detectable element while pushing the detectable element or attachment with an operator's hand during the picking operation of the operator.

  In this way, in the middle of a series of picking operations, the operator can press the detectable element such as the RF tag and the detection device such as the wearable RFID reader / writer can detect the detectable element on the work shelf. A detectable element is attached. This eliminates useless movement in the picking operation and improves the work speed.

  Preferably, in the present invention, the ID of the detection device is assigned to the detection device by associating the detection device with an ID that is identification information such as an identification code unique to the detection device on the system. And means for grasping the work history for each worker.

  Further, the wireless communication ID of the wearable detection device can be the ID of the worker who is using the detection device. This makes it possible to grasp the work history for each worker. By analyzing the work history for each worker, an optimization program for each worker and a work improvement program for reducing work time can be created. Also, by recording the work history for each worker, it is possible to improve traceability, increase the response speed when a problem occurs, and easily improve the problem location.

That is, if there is an ID unique to the worker, even if a plurality of workers jointly perform a picking work on one picking work shelf, the work history can be grasped for each worker, and the work shelf in which the object storage is arranged. In addition, a specific picking location can be instructed for each worker having a unique ID by attaching a lamp for displaying the location to be picked, and by using a blinking pattern or a different color of the lamp. For this reason, even if a plurality of workers jointly perform a picking work on one work shelf, the work history for each worker can be grasped, and the picking work can be made flexible.

  Preferably, in the present invention, the shelf for arranging the object storage is divided into a picking work shelf, a storage shelf for storing the object storage not to be picked, and a next picking program. When switching the model, there is an unnecessary object storage in the work shelf and means for displaying the location of the object storage to be moved from the storage shelf to the work shelf with a lamp.

  In this way, a space-saving work shelf can be obtained by arranging only the minimum necessary object storage on the work shelf. Further, by managing the movement of the object storage between the storage shelf and the work shelf, the correct object storage can be surely moved. In other words, the shelf where the object storage is placed is divided into a picking work shelf and a storage shelf that stores the object storage that is not picking work, so that when switching the model to the next picking program, By displaying the unnecessary object storage on the shelf and the location of the object storage to be moved from the storage shelf to the work shelf with a lamp, the correct object storage can be surely moved. Only the minimum necessary object storage can be placed on the work shelf. For this reason, a work shelf becomes space-saving, an operator's movement distance can be decreased, and efficient picking work can be performed.

  Preferably, in the present invention, a unique ID is assigned to the object storage to be picked, the object storage storage location of the work shelf, and the object storage storage location of the storage shelf. By associating on the system, there is a means that can always grasp which object is picked up and which object is stored and in which shelf number.

  As a result, the picking operation can be performed with the same program regardless of the work shelf number where the object storage is freely arranged. That is, a unique ID is assigned to the object storage to be picked, the storage location of the target storage of the work shelf, and the storage location of the storage of the target storage of the storage shelf, and these unique IDs are displayed on the system. By associating with the above, it is always possible to know which object storage is the object to be picked and which shelf number is in the object storage. For this reason, the system can automatically recognize the location of the object storage where the object to be picked automatically is stored, regardless of the work shelf number where the object storage is freely placed. The lamp can be automatically displayed without changing the program. Since the shelf number to be placed in the object storage is not fixed, the picking system is flexible.

  Preferably, in the present invention, means for programming the number of objects to be picked in one picking operation, means for notifying an operator of work after picking by an image, an electronic drawing, sound, etc., and after picking Means for setting the scheduled work time, and when the portable detection device attached to the worker within the set scheduled work time detects a detectable element attached to the object storage or work shelf By ignoring the detection, the detection is recognized as a malfunction of the operator until the work after the picking is completed.

  Preferably, in the present invention, the work instruction means after picking uses a laser light or an LED light that can be collimated, means for instructing the work place, and means for instructing the place of the shelf on which the light source is picked And having.

  Thereby, the number of stocks in the object storage can be displayed in real time on the digital display attached to the work shelf. In other words, when picking work, if you pick up too many objects, move the extra number back to the object storage, or pick again when you miss, picking operation and the number of objects in the object storage The number of subtractions can be corrected. As a result, the correct stock quantity can be grasped by interlocking the picking operation with the target object stock quantity in the target object storage on the system, and the stock quantity can be displayed in real time on the display of the work shelf.

  Preferably, in the present invention, the picked object having an expiration date, expiration date, etc. is time-managed on the system from the time when it is put in the object storage, and means for notifying the operator that the time limit has come. Have

  As a result, picked objects with expiration dates, expiration dates, etc. are time-managed on the system from the time they are put in the object storage, and the deadline comes by notifying the worker that the deadline has come. You can avoid accidentally forgetting and picking.

  Preferably, in the present invention, the pre-process information of the semi-finished product processed in the pre-process of the picking work is written in the RF tag attached to the semi-finished product, and the picking work process currently being worked on the RF tag.

  In this way, the pre-process information of the semi-finished product processed in the pre-process of picking work is written in the RF tag attached to the semi-finished product, and the contents information of the picking work process currently being worked on is added to the RF tag. If the current picking process is completed and the information of the previous process and the information of both processes of the current picking process are sent downstream to other subsequent processes after the current picking process is completed, the traceability of all processes can be unified.

Hereinafter, an embodiment of a picking system of the present invention will be described with reference to the accompanying drawings.
First, the basic configuration of the picking system according to the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram illustrating a basic configuration of the picking system according to the first embodiment. In this embodiment, RFID technology is used.

As shown in FIG. 1, the picking system according to the first embodiment is a system for detecting an operator's picking operation in a process of picking a plurality of parts, members, tools, products, etc. , A picking work shelf 1 in which the object storage 3 is arranged, an RF tag 7 as a detectable element attached to the picking work shelf 1 via an attachment 6, It is composed of a wearable RFID reader / writer 5 as a portable detection device and a computer 10.
Note that the RF tag 7 may be attached to the object storage case 3 via the attachment 6.

  The wearable RFID reader / writer 5 is attached to a part of the worker's body, for example, the wrist, and is in a state where the worker's hand 4 picks the object 2 or without stopping a series of picking operations. During the operation, the ID signal from the RF tag 7 is received and the RF tag 7 is detected. The detection of the RF tag 7 confirms that the operator's picking operation has reached the object storage 3 to be picked. The wearable RFID reader / writer 5 transmits the detection information to the computer 10 wirelessly as a detection signal.

  Furthermore, the design of the wearable RFID reader / writer 5, the attachment position of the RF tag 7, and the method will be described with reference to FIG. FIG. 2A is a side view of the picking work shelf before picking. The picking work shelf 1, the object storage case 3, the RF tag 7, the operator's hand 4, the wearable RFID reader / writer 5, and the digital display. 9 represents the positional relationship of the LED lamp 8 and the like. FIG. 2B shows the object storage 3 where the operator's hand is picked, and the wearable RFID reader / writer 5 attached to the operator's list with the object 2 picked is the RF tag 7. It is a side view showing the state where RF tag 7 is read, pushing down.

  FIG. 2A shows an operator's hand 4 approaching the picking work shelf 1. A wearable RFID reader / writer 5 is attached to the wrist of the operator's hand 4. As shown in FIGS. 2A and 2B, the wearable RFID reader / writer 5 is attached to the outside of the operator's wrist, that is, on the back side of the hand by a wristband. The wearable RFID reader / writer 5 is provided with an antenna (not shown) at the top, and can detect the RF tag 7 at a distance up to about 30 mm.

  On the picking work shelf 1, a target object storage 3 storing a target object 2 to be picked is placed. An RF tag 7 is attached to the attachment 6 attached to the ceiling of the work shelf 1. The RF tag 7 is placed in a flexible plastic case. Then, when the operator's hand 4 is in a state of picking an object to be picked or during a natural operation without stopping a series of picking operations, the operator's hand 4 or the wearable RFID reader / writer 5 The RF tag 7 is disposed at a position where it is pushed like a warming.

  FIG. 2B is a side view showing a state in which the operator's hand 4 reaches to the object storage 3 and grasps the object 2 to be picked. The RF tag 7 is pushed and bent upward by the operator's hand 4 or wearable RFID reader / writer 5 in a state where the operator's picking operation reaches the object storage to be picked. As a result, the wearable RFID reader / writer 5 adjacent to the RF tag 7 detects the RF tag 7.

  As described above, in the picking system of the present embodiment, the RFID tag or its attachment is used by the operator's hand in a state where the operator picks or in the middle of a series of picking operations using the RFID non-contact detection technology. The RF tag is attached so that the wearable RFID reader / writer can detect the RF tag while pushing. Accordingly, it is possible to perform a picking operation with high reliability with high reliability at the correct number of times and at the correct speed in the correct order.

  As described above, by reading the RF tag with a natural picking operation, the work can be performed efficiently in a hands-free manner. In addition, since the wearable RFID reader / writer can read a large number of picked-up object RF tags, the cost of the RFID reader / writer can be reduced.

  In addition, an LED lamp 8 for displaying a picking place for a worker and a digital display 9 for informing the picking number and the stock quantity are attached to the front surface of the picking work shelf 1 in which the object storage 3 is arranged. .

  An operator takes out an object from the object storage 3 of the place displayed by LED8 which lights up in order of the program of the computer 10. FIG. The LED 8 of the picked object storage 3 is turned off by the picking detection signal. In this way, the work procedure is instructed from the computer 10, and the LED 8 is turned on and off in a fully automatic manner according to the program.

  In addition, a specific picking location is instructed for each worker having a unique ID by displaying the lamp in a different blinking pattern or a different color.

  Furthermore, by automatically recognizing the worker-specific ID, even if a plurality of workers perform a picking operation jointly on one picking work shelf, the work history is grasped for each worker. For this reason, even if a plurality of workers jointly perform a picking work on one work shelf, the work history for each worker can be grasped, and the picking work can be made flexible.

  Further, when the worker performs an operation different from the work procedure or when the work speed is slower than the set work speed, the worker is warned by the color of the LED 8, the blinking speed, the blinking pattern, the buzzer, the vibration, or the like. The next work instruction on how to process the picked object is displayed on the computer monitor. The work instructions can use not only documents but also illustrations, electronic drawings, photographs, etc., and can be systemized so that an operator can definitely process the picked items.

  Although not shown, the storage places where the object storages are arranged are in both the picking work shelf 1 and a storage shelf (not shown) for storing the object storages that are not picked. Then, by arranging only the object storage 3 necessary for the picking work on the work shelf 1, the work shelf 1 is saved in space. As a result, the movement distance of the worker is reduced and the work efficiency is increased.

  Further, when the model is switched to the next picking program, an LED lamp 8 displays the object storage 3 that does not require a work shelf and the location of the object storage 3 that should be moved from the storage shelf to the work shelf 1. Is done.

  In addition, as a unique ID, the target object bag to be picked, the target object storage, the target storage object storage location (work shelf number) of the work shelf, and the target storage object storage location (storage shelf number) of the storage shelf Serial number, barcode, RF tag, etc. are attached. By reading these unique IDs and associating them on the system, it is always possible to know which object is stored in which object storage, and what number on which shelf, where the object is stored. Is done. Thereby, the installation place of a target object storage becomes free. Further, as described above, real-time inventory management, operator malfunction correction, and work instructions after picking are systemized.

  The computer 10 is programmed with the number of objects to be picked in one picking operation. Then, the LED lamp 8 and the digital display 9 on the front surface of the picking work shelf 1 notify the operator of an instruction for the work after picking by an image, an electronic drawing, a voice, or the like. The computer 10 also sets the scheduled work time after picking.

  If the wearable RFID reader / writer 5 attached to the worker detects the RF tag 7 attached to the object storage 3 or the picking work shelf 1 within the set scheduled work time, the detection is ignored. Until the computer 10 finishes the work after picking, the detection is recognized as a malfunction of the operator.

  Further, the computer 10 automatically subtracts the inventory number of the picked object 2 stored in the figurine storage 3 in conjunction with the picking operation, and adds the replenishment number when replenishing the object storage. Good.

  Furthermore, the computer 10 manages the time for the target object 2 to be picked, such as the expiration date and the expiration date, on the system from the time when the target object 2 is put into the target object storage 3, and confirms that the time limit has come. The operator should be informed by the digital display 9.

  And since the picking system of this embodiment is a closed loop picking system, the work situation for every worker and the stock situation of the target object to be picked in the target object storage are grasped in real time. Further, by analyzing the work history for each worker, an optimized picking program or work improvement program for each worker can be created, which can be used for improving work efficiency and preventing erroneous work. In addition, traceability for each worker can be established.

  Further, not only reading information from the RF tag 7 but also using the function of writing information to the RF tag 7 which is one of the characteristics of the RFID, the RF tag information is shared not only with the picking process but also with the previous and subsequent processes. It becomes possible. As a result, traceability of the entire process is established.

  That is, in accordance with an instruction from the computer 10, the wearable RFID reader / writer 5 writes the pre-process information of the semi-finished product processed in the pre-picking process to the RF tag 5 attached to the semi-finished product. The contents information of the picking work process currently being worked on is added and overwritten, and after the current picking process is completed, the information of the previous process and the information of both processes of the current picking process can be flowed downstream to other subsequent processes.

  Next, with reference to Fig.3 (a) and FIG.3 (b), the picking system of 2nd Embodiment of this invention is demonstrated. The picking system of the second embodiment has the same configuration as that of the first embodiment except that the method of attaching the RF tag 7 to the picking work shelf 1 is different.

  Also in the second embodiment, as in the first embodiment, the RF tag 7 is suspended from the picking work shelf 1 by the attachment 6. However, in the second embodiment, the RF tag 7 itself does not have flexibility, and the attachment 6 is formed of a flexible material such as a leaf spring or rubber. Therefore, as shown in FIG. 3B, when the RF tag 7 is pushed by the operator's hand 4 or the wearable RFID reader / writer 5, the attachment 6 is broken. As a result, the RF tag 7 comes close to the wearable RFID reader / writer 5 and the RF tag 7 is detected. In the second embodiment, the RF tag 7 may also have flexibility.

  Next, with reference to Fig.4 (a) and FIG.4 (b), the picking system of 3rd Embodiment of this invention is demonstrated. The picking system of the third embodiment has the same configuration as that of the first embodiment except that the manner of attaching the RF tag 7 to the picking work shelf 1 is different.

  Also in the third embodiment, as in the first embodiment, the RF tag 7 is suspended from the picking work shelf 1 by the attachment 6. However, in the third embodiment, the attachment 6 is formed of a flexible material including fibers such as a string or a thread. Therefore, as shown in FIG. 4B, when the RF tag 7 is pushed by the operator's hand 4 or wearable RFID reader / writer 5, the attachment 6 is deformed. As a result, the RF tag 7 comes close to the wearable RFID reader / writer 5 and the RF tag 7 is detected.

  Next, with reference to Fig.5 (a) and FIG.5 (b), the picking system of 4th Embodiment of this invention is demonstrated. The picking system of the fourth embodiment has the same configuration as that of the first embodiment except that the method of attaching the RF tag 7 to the picking work shelf 1 is different.

  Also in the fourth embodiment, the RF tag 7 is suspended from the picking work shelf 1 by the attachment 6 as in the first embodiment. However, in the fourth embodiment, the attachment 6 has a hinge 60. For this reason, as shown in FIG. 5B, when the RF tag 7 is pushed by the operator's hand 4 or the wearable RFID reader / writer 5, the attachment 6 is folded at the hinge 60. As a result, the RF tag 7 comes close to the wearable RFID reader / writer 5 and the RF tag 7 is detected.

  Next, with reference to FIG. 6A and FIG. 6B, a picking system according to a fifth embodiment of the present invention will be described. The picking system of the fifth embodiment has the same configuration as that of the first embodiment except that the method of attaching the RF tag 7 to the picking work shelf 1 is different.

  Also in the fifth embodiment, as in the first embodiment, the RF tag 7 is suspended from the picking work shelf 1 by the attachment 6. However, in the fifth embodiment, the attachment 6 includes the first piece 61 and the second piece 62 that form a certain angle with respect to the hinge 60. The RF tag 7 is attached to the second piece 62. As shown in FIG. 6A, the two pieces 61 and 62 are configured such that the first piece 61 extends substantially downward from the hinge 60 and the second piece 62 enters the operator's hand 4 from the hinge 60. It is biased by a spring (not shown) so as to extend obliquely upward in the coming direction.

  Therefore, as shown in FIG. 6B, when the first piece 61 of the attachment 6 is pushed by the operator's hand 4 or the wearable RFID reader / writer 5, the first piece 61 and the second piece 62 are hinged 60. And the second piece 62 is lowered. As a result, the RF tag 7 comes close to the wearable RFID reader / writer 5 and the RF tag 7 is detected.

Next, a sixth embodiment of the present invention will be described with reference to FIG.
FIG. 7 is a perspective view of a work table employing the picking system according to the sixth embodiment of the present invention. The picking system of the sixth embodiment is basically the same as that of the first embodiment, and the configuration of the attachment 6 for attaching the RF tag 7 to the picking work shelf 1 is the same as that of the first to sixth embodiments. Any one may be adopted.

  In this embodiment, instead of the LED lamp 8 attached to the picking work shelf 1, a light source unit 13 that stores laser light or LED light that can be collimated is provided. The light source unit 13 is supported above the work table 11 by the support member 12. The light source unit 13 can freely swing the neck by a stepping motor controlled by the computer 10. Thereby, the irradiation direction of the LED light which can be made into a laser light source or parallel light is controlled. Then, as indicated by a dotted line I in FIG. 7, the object storage 3 to be picked is instructed by beam light irradiation from the light source 13.

  Furthermore, after the target object 2 such as an electronic component is picked from the target object storage 3, the work place after the picking, for example, as shown by the dotted line II in FIG. 7, should be attached. The printed circuit board 14 is instructed by the light beam irradiation from the light source 13. The parallel light from the LED light illuminates the work place as a spotlight having a diameter of about 2 to 3 cm, for example. For this reason, irradiation light is useful also as illumination of the assembly place of a printed circuit board.

  Thus, in 6th Embodiment, instead of the LED lamp 8 and the digital display 9 which were attached to the picking work shelf 1 in the above-mentioned 1st-5th embodiment, the LED light which can be made into a laser beam or parallel light is used. . As a result, it is possible to easily instruct the object storage 3 to be picked in the picking work shelf 1 without constructing wiring for lighting the LED lamps 8 and the like on the picking work shelf 1.

  And in this embodiment, since it is not necessary to attach an LED lamp and a digital display for every object storage 3 of the picking work shelf 1, wiring for the LED lamp and the digital display for every target storage 3 is provided. It is unnecessary. For this reason, hardware costs such as LED lamps and digital displays can be reduced, and wiring construction costs are also unnecessary. Furthermore, when the layout of the picking work shelf 1 is changed due to the increase or decrease of the object storage 3 or the like, there is no need to rewire these LED lamps and the like, and operational flexibility is ensured.

  In each embodiment mentioned above, although the example which constituted the present invention on specific conditions was explained, the present invention can perform various change and combination, and is not limited to this. For example, in the above-described embodiment, an example has been described in which RFID technology is used, the portable detection device is a wearable RFID reader / writer, and the detectable element is an RF tag. However, the present invention is not limited to this. For example, the same effect can be expected when a wearable barcode scanner is used as a detection device and a barcode is used as a detectable element.
