[Embodiment]
Hereinafter, the picking equipment according to the present embodiment will be described with reference to FIGS.
Briefly describing this picking equipment, a container (an example of a collection container) transported along a predetermined transport path is used to store a large number of types of articles (also products) disposed along the transport path. An operator (also referred to as a picker) picks (collects) an item related to the order of a sorting destination from a storage shelf stored in advance, and a container corresponding to the sorting destination arrives. (Or when it arrives), the article picked on the temporary table is put into the container, and the article is weighed on the temporary table (by gravimetric inspection, the type of the article) Or the number can be checked). Further, in this picking facility, a picking work area by an operator is determined, and according to the picking work area, the range of the article storage unit in the storage shelf, that is, the frontage in charge of the worker and the temporary storage table in charge of the work Is determined in advance.

  That is, as shown in FIG. 1 and FIG. 2, the picking equipment includes a transfer conveyor (specifically, a roller conveyor) that is a transfer means for transferring the containers 1 in order along a predetermined transfer path R. Used, but a belt conveyor may also be used), a storage shelf 3 for storing many types of articles arranged along the conveyor 2, the storage shelf 3 facing the storage shelf 3, and the above transport It is comprised from the temporary placement stand 4 group of the goods arrange | positioned above the conveyor 2, and the control apparatus (shown in FIG. 6) 5 which controls the sorting operation | work in this installation.

  The storage shelf 3 is partitioned into a plurality of picking work areas (hereinafter referred to as work zones) Z1 to Zn (in FIG. 1, 11 (n = 11) are provided) with frontage of a predetermined width. A plurality of article storage units 11 are provided for each work zone Z. Each article storage unit 11 stores articles for each type.

  A predetermined number (for example, five) of the temporary placement tables 4 is arranged for each work zone Z, and the weight (mass) of each temporary placement table 4 is measured to correctly pick an article. A measuring device (a weight inspection device, a so-called scale is used) 12 for checking whether or not it is present is arranged.

  A first display (storage unit side display) 13 is disposed at the opening of each article storage unit 12, and a second display (temporary storage side display) 14 is provided on each temporary storage table 4. Is arranged.

  As shown in FIG. 4, the first indicator 13 can display at least the article storage section 11 to be taken out with a lamp, and displays a work completion button 13a for notifying the completion of the work and the number of articles to be taken out. A number display portion (for example, a digital display screen) 13b and a forced completion button (also referred to as a cancel button) 13c are provided.

  As shown in FIG. 5, the second indicator 14 can display at least the temporary table 4 to be picked with a lamp and can issue an alarm when the measured value is incorrect (in an example of an alarm unit). More specifically, a lamp that can display an alarm color different from the color that displays the temporary table to be picked or that can change the blinking interval is used) and a work completion button 14a that can notify the completion of the picking work (This button has a plurality of functions, but of course, a button may be provided for each function, and an alarm lamp as an alarm unit may be provided separately for alarms) A number display section (for example, a digital display screen) 14b for displaying the number of items, a forced completion button (also referred to as a cancel button) 14c, and an article to be copied after the picking operation is completed. And poured button 14d indicating that turned work has been completed as well as displayed on the lamp is provided that the container 1 can be poured.

  Although not shown, each work zone Z of the storage shelf 3 is provided with a shelf-side work completion lamp indicating that the shelf-side work for one tact has been completed. That is, an overall work completion lamp indicating that the overall work has been completed is provided.

Next, the control device 5 will be described.
As shown in FIG. 6, the control device 5 inputs article data sorted for each customer, that is, for each sorting destination, and creates predetermined various data (for example, work instruction data, control data, etc.). A general control unit (also referred to as a host system) 21, a management control unit 22 that inputs various data from the general control unit 21 and controls each display, measuring instrument, and the like. A display controller 23 for controlling the first and second displays 13 and 14 according to instructions and a measuring instrument controller 24 for controlling the measuring instrument 12 are provided. A computer is used at least for each of the control units 21 and 22.

  From the overall control unit 21, for example, article shipment data for each sorting destination (sorting destination, type of article, number, etc.), article storage position data (that is, work zone, article storage unit), article weight master data. Are output to the management control unit 22.

  From the management control unit 22, for example, a storage instruction (position display, number display) to the first display 13 of the article storage unit 11 to be taken out, a temporary placement instruction (position display, Etc.) are output to the display controller 23, and a measurement instruction to each measuring instrument 12 is output to the measuring instrument controller 24. Further, the weight inspection on the temporary placement table 4 is performed by the management control unit 22, and therefore the measurement value obtained by the measuring instrument 12 is input to the management control unit 22.

  As shown in FIG. 1, the first line measuring instrument 6 and the second line for measuring the empty weight (tare weight) of the container 1 before entering the sorting operation and the total weight after completing the sorting operation. The measuring instrument 7 is arranged in the middle of the conveyor 2 and the weight of all the items sorted into the container 1 is also checked (in some cases, the measuring instruments 6 and 7 are not arranged. Good). For example, as these line measuring instruments 6 and 7, a measuring conveyor is used. Each container 1 on the conveyor 2 is identified by, for example, an identification label such as a barcode attached to the side surface of the container 1 provided on the storage shelf 3, that is, in front of the work zone Z (upper side). This is done by reading with a bar code reader.

Here, the conveyance method of the container 1 will be briefly described.
In the present embodiment, as shown in FIG. 2, the description will be made assuming that the container 1 is tact-fed with five segments (so-called groups).

  That is, in each work zone Z, there are a maximum of five containers 1 that are handled by one worker P, that is, the temporary placement tables 4, and naturally, the five temporary placement tables 4 and the five containers 1 are a pair. 1 is associated. In the following description, the five temporary storage tables 4 in the work zone Z are numbered as the first, second, third, fourth, and fifth from the downstream side, and 5 corresponds to one tact. The individual containers 1 are also numbered as first, second, third, fourth, and fifth from the downstream side, and are handled using ordinal numbers (order numbers).

  In the picking facility according to the present embodiment, as described above, the preceding picking is performed, that is, the five containers 1 are associated with the five temporary placement tables 4. Pre-picking can be performed only for the container 1 that arrives at the position of the temporary table 4.

  For example, as shown in FIG. 3, paying attention to the work zone Z1 on the most downstream side, the first container group 1 relating to the first tact shown by # 1 to # 5 has arrived on the transfer conveyor 2. However, in the work zone Z1, in the second container group related to the next tact, the containers 1 of # 6 (first), # 9 (fourth), and # 10 (fifth) are targeted for the preceding picking. Furthermore, the third container 1 group related to the next tact is the container 1 of # 12 (second) and # 13 (third).

Thus, since the container 1 is tact-fed by five, the ordinal numbers of the temporary table 4 and the container 1 group match each other.
Next, picking work in the picking facility will be described.

  First, prior to the sorting operation, various data are output from the overall control unit 21 to the management control unit 22, and from the management control unit 22 to the display controller 23 and the weighing instrument controller 24 according to the sorting destination, respectively. It is assumed that the work display data and weighing data are output.

  When the sorting work is started, the work display data (lamp lighting instruction data, number of pieces) is displayed on the first display 13 of each article storage unit 11 and the second display 14 of the temporary table 4 for each container 1 that is a sorting destination. Data) and weighing data [e.g., single item weight, total weight of articles to be picked] are output to the weighing device 12, respectively.

  Focusing on the work in the first work zone Z1, since there are five temporary storage stands 4, there are five containers that can be picked in advance, but as described above, the container 1 is tact-fed, The first temporary table 4 is subjected to preceding picking with respect to the container 1 with the number (#) of 5N (N = 0, 1, 2,..., The same applies below) +1 (the ordinal number is 1). The second temporary placement table 4 can be pre-picked for the container 1 with the number (#) of 5N + 2 (the ordinal number is 2). That is, it is possible to perform the preceding picking for the container 1 having the number (#) of 5N + n (ordinal number) on the temporary table 4 having the ordinal number n (integer of 1 to 5).

  Here, when the correspondence between the temporary table 4 and the container 1, that is, the allocation method is generally described, a predetermined number n of containers 1 equal to the number of the temporary table 4 are intermittently conveyed for each work zone Z. When the preceding picking table 4 is picked, the ordinal number indicating the position of the temporary placing table 4 in the work zone Z matches the ordinal number assigned to the predetermined number n of the containers 1 that are intermittently conveyed. As described above, the article is picked on the temporary table 4.

  At the time of the preceding picking, the work completion button 14a of the second display 14 of the temporary table 4 blinks (for example, green) and the total number to be picked is displayed on the number display portion 14b. After the work completion button 13a of the first display 13 provided at the frontage portion is lit, the work completion button 13a is removed from the article storage unit 11 in which the work completion button 13a is lit, and the work completion button 13a is pressed. Pick on the table 4. This operation is all performed on the article storage unit 11 in which the operation completion button 13a of the first display 13 is lit. When the work completion button 13a is pressed, the display of the number display portion 13b is maintained and the lamp of the work completion button 13a is turned off.

When the picking of all articles is completed, the work completion button 14a of the second display 14 provided on the temporary table 4 is pressed.
When the work completion button 14a is pressed, the weighing instrument 12 is activated, the total weight of the articles picked on the temporary table 4 is weighed, and the measured value and the weight data input from the overall control unit 21 are obtained. The weight inspection is performed by comparison.

  When there is no error between the two, that is, when the measured value is correct, the lamp of the work completion button 14a is turned off and the whole work completion lamp is turned on, and the apparatus enters a standby state for putting the article into the container 1.

  On the other hand, when the measured value is not correct, that is, when a picking error has occurred, the lamp of the work completion button 14a is in a blinking state (alarm display) in red (in this case, the lamp becomes an alarm unit).

  Thus, if it is not correct, the total number display remains on the number display unit 14b (the display is maintained), and the number display unit 13b of the first display 13 of the article storage unit 11 also has the previous display. Since the number display state is maintained (held), the picking of the article by the worker P can be performed again. That is, even when a picking mistake occurs, the picking operation can be easily and reliably re-executed.

When this re-picking operation is completed and the forced completion button 14c is pressed, the lamp of the operation completion button 14a is turned off and the entire work completion lamp is turned on.
Thus, when the picking work for the # 1 container 1 is completed, the next picking work for the # 9 container 1 is performed, and when this is completed, the picking work for the # 10 container 1 is performed.

  When the picking work for the temporary storage table 4 corresponding to the # 10 container 1 is completed, the preceding picking work for the container # 12 (ordinal number is 2) 1 in the second container 1 group related to the next tact is performed. Done. When the preceding picking operation is completed, the preceding picking operation is similarly performed on the container 1 of # 13 (the ordinal number is 3). In this case, the second and third temporary placement tables 4 with ordinal numbers are used.

  Of course, the picking work is similarly performed in the other work zones Z on the upper side, and when the picking work in all the work zones Z is completed, the container 1 is automatically transported by one tact and the next The container group related to the tact is moved. That is, # 6 container 1, # 9 container 1 and # 10 container 1 arrive, and when these containers 1 arrive at the temporary table 4 in the first work zone Z1, the input button 14d of the second display 14 is displayed. The lamp is turned on, and an article picked on the temporary table 4 is put into the container 1 that arrives corresponding to the temporary table 4 by the worker P. When the loading is completed, the loading button 14d is pressed to notify the completion of the loading operation (to the management control unit and the general control unit). The input button 14d lamp and the overall work completion lamp are turned off.

  However, when the articles on the temporary table 4 corresponding to the container 1 related to the next tact are not put in and the third group of containers 1 related to the next tact arrives, the second and third The lamp of the loading button 14d of the temporary placing table 4 is turned on, and the worker P loads the article into the container 1 of # 12 and the container 1 of # 13.

  In this way, the same number of temporary placement stands as the number of containers related to tact transfer are arranged in each work zone so that the preceding picking can be performed for the number of containers, so that the efficiency of picking work is improved. Furthermore, in each temporary placing table, since the number of picked items is checked based on the weight of a single item, that is, weight inspection is performed, for example, weighing is performed at a position before the picking operation is started. Compared with the case where inspection is performed based on the actual weight of all picked articles obtained from the empty weight of the container and the total weight including the container after the completion of the picking operation, the inspection accuracy can be significantly improved.

  In other words, in order to perform inspection for each work zone, that is, in each work zone, usually, most of the articles to be taken out are one type and at most only a few types, so the number and type by weight are accurately checked. be able to.

  On the other hand, when weight inspection is performed on a container in which all articles are charged, if there is a mistake in loading for a plurality of types and a situation in which the mutual error is offset occurs, the inspection is normal. However, according to the configuration of the present embodiment, it is possible to prevent such an erroneous determination from being made.

  In the above description, the description has been given assuming that the temporary placement table that the worker is in charge of alone is five. However, the number is not limited to five, and may be four or less, or six or more, for example. . In addition, a lamp is provided on each display button to provide a display function such as a work position, an alarm function, etc., but each can be provided independently, that is, the lamp and the button can be provided separately. .

  By the way, in the above embodiment, it has been described that the next picking operation is performed when the measurement value by the measuring instrument is correct. However, even if the measurement value is not correct, that is, regardless of whether the measurement value is correct, It can be configured such that a picking operation can be started. In this case, after the next picking operation is completed, the picking operation is performed again on the temporary placement table whose measurement value is not correct.

By configuring in this way, it is not necessary to wait for the weighing time, and it is possible to immediately move to the next picking work, so that the working time can be shortened.
Further, in the above-described embodiment, it has been described that the worker inputs the article from the temporary table to the container. However, for example, it may be performed automatically.

Furthermore, although the case where the container is tact-transported has been described in the above embodiment, the present invention can also be applied to the case where the container is continuously transported.
In the case of tact transport, the number of temporary storage bases is provided according to the number of containers transported in relation to tact.However, in the case of continuous transport, there is no such restriction, and the order of occurrence of preceding picking is not required. It is only necessary to pick an article on the temporary table and put it in when the container corresponding to the temporary table arrives (moves). In this case, the temporary placement table is automatically loaded into the container.

A general description of such picking equipment will be given below, focusing on the part that is continuously conveyed.
That is, this picking equipment is the same as the picking equipment described in the above embodiment.
Any of the collection containers located on the upper side from the collection container moved to the lowermost picking work area in the picking work area on the upper side than the picking work area to which a certain temporary storage base belongs. When picking ahead of time,
The temporary placement table to be temporarily placed is made to correspond in order from the lower temporary placement table to the upper temporary placement table in the picking work area to which the temporary placement table belongs,
The article is automatically loaded when the collection container corresponding to the temporary table comes to the position corresponding to the temporary table.
