Description

  The present invention relates to a picking system using a picking cart, and more particularly to a picking system having a work analysis function of a picker.

  As an industry that employs this kind of picking system, for example, there is a distribution center for goods by mail order. In mail order distribution centers, products to be delivered are usually stored in a picking zone. The picking zone includes a plurality of picking islands, and each picking island is divided into a plurality of areas. Each area is also divided into a plurality of shelves, and a large number of the same products are stored in each shelf.

  The picking system includes a host device, a cart server, and one or more picking carts. The host device and the cart server are wired or wirelessly connected, and the cart server and the picking cart are wirelessly connected. For this reason, the picking cart includes a wireless terminal device and a barcode reader. In addition to the wireless transmission / reception device, the wireless terminal device includes a data input unit and a display device. The bar code reader is for reading a bar code attached to a product. The picking cart is also loaded with a plurality of product input containers so as to be compatible with a plurality of orders.

  In order to perform picking by order, a picking plan is created in advance in accordance with order information (shipment information) from a large number of customers in the host device. The created picking plan is sent to the cart server as picking information. When an operation start input is input from a picking operator (hereinafter referred to as a picker), the cart server assigns a plurality of orders to a picker from a plurality of picking information. The assigned order is wirelessly transmitted to the picking cart as a picking instruction and displayed on the display device. The display content of the display device includes a place (area, shelf) where picking is to be performed, the number of products to be picked, a container in which the picked products are to be accommodated, and the like (for example, see Patent Document 1).

  The picker picks up a designated number of items from a place (area, shelf) designated for display on the display device while pushing the picking cart in the picking zone, and stores them in the container. Each time a picking operation for one order is completed, the picker inputs the operation completion and notifies the cart server.

  By the way, in order to improve the picking work efficiency, it is desirable to perform work result management. As a system for performing such work performance management, a work performance management system that enables work performance collection for each picker is provided. However, as shown in FIG. 9, the management information provided by the work result management system so far includes the number of product items in units of one order, the number of picking for each product item, the total work time required for it, and the unit time. It is about the number of operations per hit, and is insufficient as management information.

  Therefore, in order to obtain information that is actually effective for improving work efficiency, a work analysis technique in the field of IE (Industrial Engineering) is employed. In this type of work analysis, the work is videotaped for each picker. Then, a specialized analyst obtains the required time for each elemental work (small classification) as shown in FIG. 10 while watching the video image, and finds an improvement in the work.

  However, since such work analysis is difficult unless it is a person with specialized knowledge, it is necessary to send the video taken to a specialist and have it analyzed at an expensive price.

Japanese Patent Laid-Open No. 2003-76753

  An object of the present invention is to provide a picking system capable of collecting and analyzing work time for picking in work subdivided from order units, so-called element work units.

  The picking system according to the present invention is a server that receives picking information from a host device and transmits a picking instruction indicating at least a picking place, article, and number in response to a request from the picker, and moves with the picker between the server and the server. At least one terminal device capable of wireless transmission / reception and having a display unit for displaying the picking instruction, wherein the terminal device performs a work analysis mode determined in advance as needed An execution means, wherein the predetermined work analysis is performed for a plurality of element work set in advance with respect to the work performed by the picker, and the work analysis mode execution means is configured to execute the work analysis mode while executing the work analysis mode. Equipped with measuring means to measure work time individually for multiple element work, And transmits the serial server.

  In the picking system, the measuring means includes input means for inputting start and end timings for one or more of the plurality of element operations.

  In the picking system, as the host device, the picking information is transmitted to the server based on a picking plan created based on a plurality of order information, while the measurement result is received via the server and a work analysis process is performed. The management apparatus which performs is provided.

  In the picking system, the terminal device is preferably mounted on a picking cart that moves together with the picker. In this case, the picking cart can be equipped with one or more containers for loading articles picked up based on the picking instruction, and the terminal device further reads information for reading information attached to the goods. And a control unit also serving as the work analysis mode execution means.

  In the picking system, the terminal device may be a portable wireless terminal.

  According to the present invention, since the work time can be measured for each subdivided element work, the work improvement point can be easily found.

  By comparing the work times measured among a plurality of workers, it is possible to accurately perform individual ability evaluation.

  The above-described work improvement points and ability evaluation can be performed without specialized knowledge at a place closer to the work site, and improvement in work efficiency can be realized without paying expensive consideration.

  With reference to FIG. 1, the structure of the picking system by this invention is demonstrated. The picking system includes a host device 10, a cart server 20, a communication antenna 30 installed in the picking zone, and a picking cart 40 that is pushed by the picker and travels (only one is shown for convenience). The host device 10 and the cart server 20 are preferably arranged in the office of the distribution center rather than in the picking zone, but the arrangement location is not particularly limited.

  The host device 10 has a function as a management device that creates a picking plan based on order information received from a plurality of customers, and can be realized by a personal computer or the like. The picking plan is, for example, an operation of dividing a plurality of order information into a plurality of shipping batches. The host device 10 also has a function of analyzing data obtained in a work analysis mode to be described later.

  The cart server 20 is connected to the host device 10 by wire (or may be wireless) and can perform two-way communication. The cart server 20 receives the picking plan created by the host device 10 as picking information in units of shipping batches. The cart server 20 holds the picking information received, performs allocation by order in response to a request from the picker, and transmits the allocated order to the picking cart 40 as a picking instruction. The cart server 20 also has a function of relaying information transmitted from the picking cart 40 to the host device 10 when the work analysis mode is executed.

  Communication between the cart server 20 and the picking cart 40 is performed wirelessly via the communication antenna 30, and bidirectional communication is possible. That is, a terminal device is mounted on the picking cart 40, and an antenna 41 for wireless transmission / reception that forms part of the terminal device is provided. Of course, since there are many cases where a plurality of picking carts exist in the picking zone, identification information for identifying the picking cart is attached to the transmission signals from the cart server 20 and the picking cart 40.

  FIG. 2 shows an example of the picking cart 40, and in the following, an example that can handle up to four pieces of order information will be described.

  The picking cart 40 can be equipped with four containers 50 for loading products picked by order into a hand-drawn cart body. The picking cart 40 also includes a display unit 42 for displaying a picking instruction from the cart server 20 and other information, a data input unit 42-1, and a bar code ( Usually, a barcode reader 43 for reading a JAN code), a label printer 44, a control unit 45, and a battery 46 for supplying electric power to each of the above units are mounted. The picking cart 40 is further equipped with an indicator 47 including a digital display for instructing the picking quantity of the product and a loading push button for informing the completion of the product to the container 50 for each mounting part of the container 50. The display unit 42, the data input unit 42-1 and the control unit 45 can be collectively realized by a laptop personal computer or the like.

  In any case, the control unit 45 is connected to the antenna 41, the display unit 42, the data input unit 42-1, the barcode reader 43, the label printer 44, and the indicator 47, and picking instructions from the cart server 20 and barcode readers. The bar code information read in 43 is displayed on the display unit 42, the picking number is displayed on the indicator 47, and the work analysis information obtained by executing the work analysis mode described later is transmitted to the cart server 20. The control unit 45 also causes the label printer 44 to print a description (for example, product name, product code, number of items, delivery destination, etc.) indicating the contents for each order in response to an instruction from the picker. The work analysis mode is executed based on a program created in advance and stored in a storage device attached to the control unit 45. The data input unit 42-1 also has an input function using a touch panel, a push button, or the like in the display unit 42 in addition to an input unit using a keyboard or the like.

  Here, an example of the layout of the picking zone will be described with reference to FIG. Usually, the picking zone is composed of a plurality of (here, four) islands I1 to I4. Each island is divided into a plurality of (here, five) areas, and each area is further partitioned by a plurality of shelves (not shown). And although different goods are stored for every shelf, depending on the case, each shelf may be further subdivided. The cart server 20 grasps the layout including such product arrangement. When the cart server 20 receives the picking information, the cart server 20 searches for the location of the product indicated there, and then goes around in the picking zone. Determine the route.

  The picking instruction from the cart server 20 is, for example, information for instructing how many items to be picked from which shelf in which picking area. For example, when the products included in the four picking instructions allocated to a certain picking cart 40 exist in the picking areas A3, B1, C2, D4, and F3, the cart server 20 first selects A3-B1-C2-D4-F3. These routes are determined and displayed on the display unit 42 in order. That is, the shelf of the picking area A3 is first designated on the display unit 42, and the display for designating the product and the number is displayed. Upon receiving these picking completion reports, the shelf of the picking area B1 is designated next. At the same time, a display for designating the product and the number is displayed. Of course, in this display, the display unit 42 and the indicator 47 can distinguish between the four picking instructions, that is, which of the four containers 50 the picked goods are put into. This display form will be described later.

  The picker walks while pushing the picking cart 40 along the path between the islands I1 and I2, I2 and I3, I3 and I4, and picks the designated item by looking at the picking information displayed on the display unit 42 and the indicator 47. I do.

  The work analysis mode, which is a feature of the present invention, will be described below. However, this work analysis mode is not always performed, and is performed only when there is an instruction from the picker. In addition, it is assumed that the cart number and the worker code are input in advance.

  For the work analysis, the work performed by the picker is classified and set in advance as shown in FIG. There are five major categories: “preparation”, “movement”, “picking”, “container replacement”, and “post-processing”. Of these, “preparation” is divided into two sub-category elemental operations, “put container” and “set start”. The work content of “loading a container” is to carry the picking cart 40 to a container storage place and load four containers 50. The work content of “set start” is to set work start and work analysis mode execution.

  “Movement” is divided into two sub-category element operations, “movement to picking place” and “movement to unloading site”. The work content of “move to picking place” is to move to the shelf of the designated picking area by looking at the picking information displayed on the display unit 42, and the work content of “move to unloading site” Is to move to the unloading place after the completion of picking work for all commodities.

  “Picking” is an elemental work of five sub-categories: “Walk in the air + take the product”, “take the product”, “read the barcode of the product”, “enter the quantity”, and “put into the container”. Divided. The work content of “walking in the air + picking up the product” is to stop the picking cart 40, walk a little from there to pick up the product on the shelf, and return to the picking cart 40. The reason for setting such work contents is as follows.

  Usually, the picker pushes the picking cart 40 to the nearest to the shelf of the picking area displayed on the display unit 42, that is, the target place, and picks up the commodity simply by reaching out without leaving. This is the work content of the above-mentioned “take a product”. However, for some reason, such as the presence of another picker and picking cart, the picking cart 40 may not be pushed to the destination location. In this case, the picker is forced to stop the picking cart 40 at a location slightly away from the target location, go to the target location empty from there, pick up the goods, and return to the picking cart 40. Such a work content is “walking in the sky + taking a product”.

  The work content of “read barcode of product” is that the barcode reader 43 reads the barcode of the picked product. The work content of “input quantity” is to input the quantity from the keyboard when there are a plurality of picked products, and the work content of “input to container” is to input the picked product into the container 50. It is.

  “Container replacement” is divided into two sub-category elemental operations, “apply label” and “replace container”. The work content of “applying a label” is to cause a label indicating the content of the container 50 to be printed by the label printer 44 and to be attached to the container 50 when the container 50 is full of products. “Replace the container” is to push the filled container 50 into the back of the picking cart 40 and place an empty container. Such empty containers are placed everywhere using the empty space in each picking island without returning to the container place.

  “Post-processing” is only one sub-category elemental work of “unloading a container”, and the work content is to unload a container into which a product has been put into a car at the unloading point.

  In the picking system according to the present embodiment, the work time required for the work of each of the above-mentioned small classifications is measured for work analysis. The measuring means for this is realized as follows. The work time is measured by a timer function built in the control unit 45. As will be described in detail later, when any operation is performed through the data input unit 42-1, the control unit 45 measures the time until the next operation is performed. Of course, this operation also includes a touch panel operation on the display unit 42.

  5 and 6 show examples of display contents on the display unit 42, and FIG. 5 shows display contents for work start setting displayed prior to work start. In FIG. 5, “work start”, “end”, “work analysis” and the like are displayed in addition to the display of the cart number and the worker code. In particular, items (icons) such as “work start”, “end”, and “work analysis” can be set and input in a touch panel format. Accordingly, when the picker starts picking work while executing the work analysis mode, the picker performs a setting operation of pressing the “work start” and “work analysis” icons. Then, the display content of the display unit 42 is switched to the display content for the picking instruction shown in FIG. “End” is pressed when the picker finishes all picking designated on the display unit 42 and stops the work. Of course, the display content of FIG. 5 and the display content of FIG. 6 may be displayed together.

  In FIG. 6, in addition to the display of the cart number and the worker code, the location number indicating the picking location, the next location number indicating the next picking location, and the code name of the product (FA131 17 175 in FIG. 6) are displayed. . A display field 61 for displaying the code name of the product code read by the bar code reader is set below the code name display field of the product. In addition, a display field 62 is set in the central portion below it so as to distinguish the number of products to be introduced into the four containers 50. For example, the “number of inputs ½” in the upper left of the display field 62 indicates that one item is currently inserted for the designated number of products.

  By the way, some of the small-class element work described in FIG. 4, that is, the element work marked with * in the right column of FIG. 4, cannot be measured by the control unit 45 unless the picker performs a special operation. . For example, the “move to picking place” operation requires a special operation to be performed when the picker starts moving, and the start timing must be input to the control unit 45. The same applies to “move to unloading place”, “walk in the air + take goods”, “take goods”, “apply labels”, and “replace containers”. For this reason, in the picking instruction display shown in FIG. 6, items (icons) “moving”, “empty moving”, “taking a product”, “attaching a label”, “lowering a container”, and “loading a container” are displayed. ) Can be set and input in touch panel format. In addition to these, there are push buttons such as “Clear work”, “Suspend”, etc., which are not directly related to the characteristic part of the present invention, and will not be described here. This is a button indicating that no work has been performed up to that time before the measurement time data is transmitted to the cart server 20. This is because if there is no stock of a certain product for a certain order, the work of this order must be postponed.

  The control unit 45 measures the work time necessary for work analysis by combining the display form as shown in FIGS. 5 and 6 and the input means in the touch panel form.

  Below, the time measurement of the 13 small classification operations shown in FIG. 4 will be described in order. In the operation of “loading a container”, “loading a container” (FIG. 6) is input when the container of the previous operation is finished, and the display of FIG. 5 is displayed for the next operation. The time until the setting in FIG. 5 is performed is measured by the control unit 45. Similarly, the work of “start setting” is measured as the time from the setting of “work start” (FIG. 5) to the display of FIG. 6 until the setting of “move” (FIG. 6). Is done. This is because when the work is started, the next work to be performed is movement to the picking place.

  “Move to picking location” is measured as the time from the setting of “Movement” to the setting of “Walk in the air + Take the product” or “Take the product” (FIG. 6). The This is because after starting to move to the picking place, the next work is to stop the picking cart slightly before the destination place and walk in the air and pick, or stop the picking cart at the destination place. This is because picking is performed.

  The work “move to unloading site” is measured as the time from the setting of “move” to the setting of “unload container” (FIG. 6).

  The operation of “walking in the air + taking the product” is the time from the setting of “moving in the air” (FIG. 6) until the completion of reading the barcode attached to the product by the barcode reader 43. It is measured. This is because the bar code reader 43 always reads the barcode of the picked product.

  Similarly, the operation of “take a product” is the time from the setting of “take a product” (FIG. 6) to the completion of reading the barcode attached to the product by the barcode reader 43. As measured.

  In the operation of “reading the barcode of the product”, the control unit 45 can know the time required for reading.

  Also for the operation of “input quantity”, the control unit 45 can measure the time from when the barcode reading operation is completed until the quantity is input.

  The operation “inject into the container” is measured as the time from when the reading of the barcode or the input of the quantity is completed until the setting of “move” is performed. This is because, once a picked product is put into a container, it always moves to the next picking place or moves to the unloading place.

  The large classification “container replacement” is an operation performed when the container 50 is filled with products. In this case, as described above, after the picker sets “apply label” (FIG. 6), the specification indicating the contents of the container 50 that is full with respect to the label printer 42 by the data input unit 42-1 is displayed. Printing is performed and this is attached to the container 50. Subsequently, the picker sets “load a container” (FIG. 6), finds an empty container from nearby, and mounts it on the picking cart 40. From this, the operation of “applying a label” is measured as the time from the setting of “applying a label” to the setting of “loading a container”. On the other hand, the operation of “replace container” is measured as the time from the setting of “load container” until the next setting, for example, the setting of “move”. This is because the container 50 is full during picking, and the picker always moves to the next operation when the container replacement is completed.

  The operation of “unloading a container” in “post-processing” is measured as the time from the setting of “unloading a container” (FIG. 6) to the setting of “loading a container” (FIG. 6). Is done.

  As is apparent from the above description, in this embodiment, in order to measure time for a plurality of sub-class elemental operations, the touch panel type input unit is provided, and the control unit 45 performs an input operation by the input unit of the element operation. It is obtained as the start and end timing. Of course, this input means may be realized by a normal push button.

  Next, the work flow of the picker when executing the work analysis mode will be described step by step.

  First, the picker inputs a cart number, an operator code, and the like from the data input unit 42-1 by viewing the display contents of the work start setting in FIG. 5. Next, the container 50 is loaded from the container storage place at the work start point in the picking zone. Hereinafter, this picker is referred to as picker A, and the picking cart is referred to as 40A.

  Picker A sets “work start” and “work analysis” prior to work start. During the above, the work times of “load container” and “set start” are measured. The measured work time may be transmitted sequentially, but may be stored in a storage device attached to the control unit 45 and transmitted all at once after all the work is completed.

  The control unit 44 informs the cart server 20 that the picker A indicated by the inputted worker code starts work on the picking cart 40A having the inputted cart number and the work analysis mode is executed. Inform.

  The cart server 20 transmits the picking instruction allocated to the picking cart 40A. Of course, identification information indicating that the transmission destination is the picking cart 40A is attached to the picking instruction. As a result, the display unit 42 of the picking cart 40A is switched to the display content of the picking instruction as shown in FIG. Picker A who has seen this picking instruction sets “move” and starts moving to the instructed picking location.

  When picker A arrives at the instructed picking place, it sets “take a product”, and the number of products instructed on display section 42 or the number indicated by indicator 47 (total in FIG. 6). Pick 4). As described above, when it is unavoidable to stop in front of the instructed picking place, the setting of “walk with the air and take the product” is performed. During the above, the work time of “move to picking place” is measured.

  Picker A performs a reading operation of a barcode attached to the picked product. During this time, the work time of “taking a product” or “walking in the air + taking a product” is measured.

  Subsequently, when a plurality of products are put into one container, the picker A inputs the quantity from the data input unit 42-1. During this time, the work time of “barcode reading of merchandise” is measured. Subsequently, the picker A sets “inject into containers”, and the picked goods are divided into four containers 50 according to orders. During this time, the work time of “input quantity” is measured.

  When the picker finishes putting the product for each container, the picker pushes the loading push button in the corresponding indicator 47. The number of inputs is counted in the control unit 45. For example, in the upper left in the display column 62 of FIG. 6, the initial display is the input number 0/2, but when the push button is pressed once. The controller 45 sets the input number to 1/2, and when pressed twice, sets the input number to 2/2. In this way, the control unit 45 can confirm the insertion of the products for the four orders designated and displayed in the display column 62, and after confirmation, switches the display of the picking instruction to the picking instruction at the next location. Accordingly, the picker A sets “move” and moves to the next picking place. During this time, the work time of “put into container” is measured.

  Picker A performs the above-described picking operation at a plurality of instructed picking locations, and after all the picking operations are completed, sets “move” and heads to the unloading site. When you arrive at the unloading site, you can set the “unload container” setting to measure the element work time of “move to unloading site” in the “Moving” large category. When the container is transferred to the car at the unloading site, the picker sets “load container” when going to the container storage area. The time from the setting of “unload container” to the setting of “load container” is measured as the element work time for “unloading container” in “post-processing”. If there is no instruction for the next picking location from the cart server 20 and the setting of “drop container” is made, the control unit 45 displays that all the picking operations for the four orders have been completed. The display of the unit 42 is switched to the display of FIG.

  The major classification “container replacement” during picking is as described above.

  The element work time measured as described above is sent to the host device 10 via the cart server 20. The host device 10 performs work analysis processing on the work time sent. In the example of FIG. 6, the work analysis process is not a work analysis process for each four orders but a work analysis process including all four orders.

  FIG. 7 shows an example of the result of work analysis processing performed by the higher-level device 10. Here, an example of work analysis results performed on four pickers of models A, B, C, and D is shown. The number of times indicates the number of times the work analysis has been performed, and the area indicates in which area the work analysis has been performed. The number of rows indicates the item (type) of the product, and the number indicates the number of picking. The time measured for the small classification (element work) from “put container” to “drop container” is shown, and a simple average of the total number of times is calculated for each element work. In addition, for each of the major classifications of “Preparation”, “Movement”, “Picking”, “Container Replacement”, and “Post-processing”, the sum of the times of included element work is calculated as a subtotal, and the total of the subtotal The ratio to is calculated. In addition, the percentage of the total time for each elemental work is shown as a pie chart.

  According to the result of such work analysis, for example, if there is an element work that requires a large work time, it can be easily found that there is room for improvement for the element work.

  The effects of the picking system according to the present embodiment are listed as follows.

  Since the work time can be measured for each subdivided element work, it is easy to find work improvement points.

  By comparing the work times measured among a plurality of workers, it is possible to accurately perform individual ability evaluation.

  Work improvement points and ability evaluation can be performed without specialized knowledge at a place closer to the work site, and work efficiency can be improved without paying expensive consideration.

  It is possible to estimate and evaluate the effect of improvement.

  The host device can grasp the weight, size, and category (types such as bottles, cans, paper packs, foods, and daily necessities) for each product. Thus, it is possible to accurately calculate and set the standard work time corresponding to the work conditions for each type of element work.

  Based on the work analysis results, work planning can be performed accurately under different daily work conditions.

  FIG. 8 shows another example of the terminal device, which shows a portable terminal device that is not fixedly installed in the picking cart 40.

  The portable terminal device 100 includes a control unit having the same function as the control unit 45 described in FIG. 2 and a transmission / reception antenna, and includes a display unit 101, a barcode reading unit 102, and data by key input. An input unit 103 is provided. The function of the display unit 101 is the same as that of the display unit 42 described with reference to FIG. 2 except for an input function using a touch panel type icon. For this reason, in place of the touch panel type icons described in FIG. 2, push buttons for performing inputs such as “work start”, “work analysis”, “movement”, “movement of the sky”, and the like are provided in the data input unit 103. . The operation format by the picker is the same as that of the terminal device described with reference to FIGS.

  The preferred embodiments of the present invention have been described above. However, the picking system according to the present invention can be variously modified. For example, a terminal device is provided with a barcode reader so as to read a barcode attached to a product, but when information holding means such as an IC tag is attached to the product, Information reading means may be provided. Also, the major classification and minor classification element work shown in FIG. 4 are only preferable examples, and how the major classification and minor classification are classified is determined according to the content of the required work analysis.
