Description

  The present invention relates to a system for instructing an operator to load and unload items on a truck landing on a berth in a distribution center.

  At various distribution centers, for example, distribution centers that handle cased items such as canned beverages and bottled beverages, and distribution centers that handle various other items, trucks are landed on each berth attached to the warehouse and shipped. And loading / unloading goods to and from the truck at the time of arrival. This loading and unloading work is also being automated, but requires an operator to operate forklifts, other various logistics equipment and transport equipment, and other work. In a large-scale distribution center, a large number of berths are arranged in one warehouse and the arrangement width ranges from 200 to 300 m. A plurality of workers, for example, several to several tens of workers are loaded and unloaded on these berths. For example, each worker has a wireless terminal, and is performed according to an instruction from the server. In this case, generally, an unoccupied worker is allowed to perform work on a berth that is in a work waiting state.

As a support system for rationalizing work in distribution centers, a system that simulates the work time of each worker based on past performance data and sets the number of workers and the number of persons in charge of each work category has been proposed. (For example, patent document 1).
JP 2002-109003 A

  In a conventional work instruction system, each worker performs work on a berth that is waiting for work, but if the position of the work-waiting berth is far from the worker's current position, the work will move to the berth. take time. In a large-scale distribution center as described above, there are berths with a width ranging from 200 to 300 m, and an operator moves over such a long distance. The work efficiency is reduced. For this reason, many workers are required. In the support system of the above proposal example, the number of workers and the number of persons in charge of each work category is set, work is allocated, and efficiency is improved. No consideration is given to shortening the travel time.

  An object of the present invention is to reduce the waste of time required for the worker to move to the berth, the skill level of the worker, the waste due to the difference in work occurrence frequency due to the berth, the bias of work waiting, etc. It is to provide a berth work instruction system that can be used.

The configuration of the present invention will be described with reference to FIG. 1 corresponding to the embodiment. This berth operation instruction system (1) is a system for instructing workers to load and unload articles on a truck (4) landing on a berth (3). The responsible berth registration means (25) for registering the assigned berth (3) and the person in charge of the berth (3) registered in the responsible berth registration means (25) with respect to the work generated by the arbitrary berth (3) Work instruction means (26) for instructing the worker (8) to perform work.
According to this configuration, the work instruction means (26) allows the worker in charge (8) whose berth (3) is registered in the responsible berth registration means (25) to work generated in any berth (3). Work is instructed. The worker (8) loads and unloads according to this instruction. In this case, the assigned berth registration means (25) includes a plurality of assigned berths (3) for each worker (8) in consideration of, for example, the position, the skill level of the worker (8), the work occurrence frequency, and the like. ). The plurality of assigned berths (3) can be determined at positions close to each other. For this reason, the work instructing means (26), for example, selects the work of the berth (3) at a close position according to the registered contents, and the skill level of the worker (8) and the occurrence of work at each berth (3). Work according to the frequency, etc. will be instructed, and the movement time of the worker (8) to the berth (3), the skill level of the worker (8), and the difference in work occurrence frequency due to the berth (3) It is possible to reduce waste and bias due to the above, and to perform efficient work. As a result, the operator (8) can be minimized.

In the present invention, a work priority setting means (27) for setting work priorities is provided, and the work instruction means (26) works on a plurality of berths (3) simultaneously to one worker (8). In the event of a failure, the work of the berth (3) may be instructed according to the priority set in the work priority setting means (27). The work priority order setting means (27) sets, for example, which berth (3) among the plurality of berths (3) registered for each worker (8) to be given priority, or the worker (8). Regardless of, the setting of which berth (3) work is prioritized or the order of arrival of the truck is set.
As described above, the priority can be set between the berths (3) or for each berth (3), and the work is executed according to the priority order, so that the work efficiency can be further improved.

The berth work instruction system according to the present invention includes a responsible berth registering means for registering a plurality of responsible berths for each worker, and a responsible person whose berth is registered in the responsible berth registering means for any berth generation work. Work instruction means for instructing the worker to perform work eliminates waste of time required for the worker to move to the berth, waste due to differences in worker skill, the frequency of work occurrence due to the berth, bias in work waiting, etc. It can be reduced and efficient work can be performed.
If work priority setting means is provided, and the work instruction means instructs a single worker to perform berth work according to priority when a plurality of berth works are performed simultaneously, The efficiency of work can be improved.

An embodiment of the present invention will be described with reference to the drawings. This berth work instruction system 1 is a computer system that instructs each worker 8 on the loading and unloading work of goods on the truck 4 landing on the berth 3 in the distribution center 2 such as a warehouse facility.
The distribution center 2 includes a warehouse 5 on its site, a plurality of berths 3 for receiving and shipping goods by landing a truck 4 on the warehouse 5, and a truck waiting place (not shown). Yes. The warehouse 3 may be a flat place, a three-dimensional automatic warehouse, a refrigerated warehouse, or the like, but in the illustrated example, a flat place 6 and a picking place 7 are provided. The article stored in the warehouse 3 is not particularly limited, but is a cased article in which canned beverages, bottled beverages, and other various articles are accommodated in cases such as plastic cases and cardboard boxes. These articles are stacked on a pallet (not shown) and handled such as receipt / shipment in units of pallets, or handled in units of cases. Articles handled with each pallet are stored in the flat storage 6. Articles handled in case units are stored in the picking place 7, picked at the time of shipment, and palletized. The goods are transported in the warehouse 5 by, for example, a manually operated or automatically operated forklift or an in-facility transport device that travels on a track provided in the warehouse.

  FIG. 4 shows a specific arrangement example of the distribution center 2. The distribution center 2 is provided adjacent to the factory building 10 and has a plurality of warehouses 5. A plurality of berths 3 are provided along the warehouses 5 between the warehouses 5 and 5 on both sides. In the figure, a berth number is given in a rectangular figure showing the berth 3. The factory building 10 is a building that produces the above canned beverages, bottled beverages, and the like. Among the plurality of warehouses 5 and 5, the warehouse 5 on the factory building 10 side includes a flat storage 7 and a cold storage 9. The other warehouse 5 has a flat place 6 and a picking place 7.

  In the warehouse 5, an in-facility transport device 12 that travels along a predetermined route is provided, and the in-facility transport device 12 can be transported between the warehouses 5, 5 of both buildings. The in-facility transport device 12 is capable of loading and unloading articles at a specific loading / unloading section 12a. Using the in-facility transport device 12 and a forklift (not shown), the articles are transported in the warehouse 5. A palletizer (not shown) for automatically palletizing articles is provided at several locations in the warehouse 5.

  FIG. 2 shows the concept of work using this berth work instruction system 1. The berth work instruction system 1 is provided, for example, as a part of an in-center management system 20 that manages the entire distribution center 2. The in-center management system 20 issues, for example, a picking list 34 as one of the management contents. The in-center management system 20 includes, for example, a host machine 21 and a wireless terminal server 22, and the wireless terminal server 22 manages transmission / reception with the portable wireless terminal 23 held by each worker.

  As shown in FIG. 1, the berth work instruction system 1 includes a responsible berth registration means 25 and a work instruction means 26. The assigned berth registering means 25 is a means for instructing the assigned worker 8 whose berth 3 is registered in the assigned berth registering means 25 for the work generated in any berth 3. Further, the berth work instruction system 1 includes work priority order setting means 27 for setting work priorities, and the work instruction means 26 allows one worker 8 to work on a plurality of berths 3 at the same time. When this occurs, the work of the berth 3 is instructed according to the priority set in the work priority setting means 27.

In addition to this, the berth work instruction system 1 includes a worker master file 24, work status management means 28, and communication means 30.
The work master file 24 has worker-specific registration units 24a that store registration information about individual workers 8 for the number of workers. In each worker-specific registration section 24a, information on worker codes, worker names, skill levels, work in charge, berths in charge, and palletizers in charge is registered. The registration about the skill level is, for example, two types of classification information such as high and low. In the registration of the work in charge, the classification information of the work type that the worker 8 is in charge of is registered. The types of work include loading and unloading and receiving inspection etc. as work performed at the berth 3, and picking and manufacturing warehousing etc. as work performed at places other than the berth 3. As for loading and unloading, it may be divided into warehousing and delivery, and may be further classified as appropriate. In the registration for the work in charge, in addition to the work type category information, priority level information of each category in charge is registered. The registration of the palletizer in charge registers the number of the palletizer in charge.

  In the worker master file 24, the registered berth is registered for the berth number of the berth 3 for which the worker 8 is responsible. For example, if the first worker 8 is in charge of the berths 3 to 4 and the second worker 8 is in charge of the berths 3 to 4-6, the first worker 8 is 1 The fourth berth number is registered as the assigned berth 3 for the second worker 8. The berth number of the assigned berth may be duplicated among the workers 8. It is free to register which berth 3 is to be registered in the worker master file 24. However, the berth 3 in charge is considered in consideration of, for example, the position of the berth 3, the skill level of the worker 8, the frequency of work occurrence of each berth 3, and the like. It is preferable to select and register.

  The assigned berth registration means 25 is a means for collecting information on the assigned berth of each worker 8 registered in the worker master file 24 in this way. The assigned berth registration unit 25 may be a unit physically provided separately from the worker master file 24 or may be a part of the worker master file 24. FIG. 3 shows an example of registration contents of the assigned berth registration means 25.

  The work priority order setting means 27 is not related to, for example, the setting of which berth among the plurality of berths 3 registered in the assigned berth registration means 25 for each worker 8 is prioritized, This is a means for setting a priority order such as setting which berth 3 work is given priority or giving priority to the order of arrival of the truck. In the worker master file 24, for each worker 8, it is possible to register not only the assigned berth but also the priority order of which assigned berth is prioritized by the worker. In that case, the priority order information about the assigned berth registered in the worker master file 24 may be the registered contents of the berth priority order setting means 27.

  The work status management unit 28 is a unit that manages the status of whether or not the work performed by the worker 8 is occurring in each berth 3 or each part in the warehouse 5. The work status management means 28 has a work wait status notification means 29 and notifies the terminal 23 via the communication means 30 of what work wait is present. The notification of the presence of work waiting by the work waiting status notifying means 29 is performed only for the work for which the worker 8 is in charge, in accordance with the registered contents of the worker master file 24 or the assigned berth registration means 25.

The communication means 30 is means for controlling communication between the host machine section of the berth work instruction system 1 and the plurality of terminals 23 possessed by each worker 8, and is configured by the wireless terminal server 22 of the example of FIG. Is done.
The terminal 23 has a screen display means 31 such as a liquid crystal screen and a keyboard or other input means (not shown). The input means and the means for processing the input are used for the work instruction means 26. Work request means 32 for making a work instruction request is configured. The work request means 32 outputs a work instruction request signal by turning on a predetermined key, for example. The terminal 23 is, for example, a mobile phone type. For example, the terminal 23 inputs the worker code on the initial screen after the power is turned on, and causes the work instruction means 26 and the like to recognize which terminal 23 the worker 8 has.

The work instruction means 26 is a means for outputting a work instruction to the terminal 23 of the worker 8 in charge, and outputs a work instruction in response to work instruction request information from the terminal 23. When there is a work instruction request, the work instruction means 26 searches for the work in charge of the worker 8 who should have the terminal 23, and outputs the work instruction if there is a work in charge. If there is no work, information indicating no work is output. In the work instruction means 26, the presence / absence of work handled by the worker 8 and what kind of work is performed are recognized by collating with the work status management means 28.
The work instruction by the work instruction means 26 is performed according to the set work allocation rule 26a. As the work allocation rule 26 a, a rule that instructs work on the assigned berth registered in the assigned berth registering means 25, a rule that prioritizes selection of berths according to the priority set in the work priority setting means 27, and work Rules for selecting the work in charge registered in the person master file 24 and in accordance with the priority order are set. The work allocation rule 26a also defines which of the plurality of rules has priority.

  Next, the work instruction request by the berth work instruction system 1 and the form of the work instruction will be described with reference to FIG. Each worker 8 in the warehouse 5 displays what kind of work he / she is currently in charge of on his / her terminal 23. In the example of FIG. 2, presence / absence is displayed by the presence / absence display unit 33 arranged in the display of each work item on the screen. In the presence / absence display portion 33, a black portion in the drawing indicates that there is work. In the figure, as the work items in charge, manufacturing warehousing, in-house moving warehousing, picking, etc. are displayed in text, and it can be seen that there are manufacturing warehousing and picking work. The worker 8 makes a work instruction request from the terminal 23 while seeing this display. In response to this work instruction request, the work instruction means 26 returns a work instruction in accordance with the work allocation rule 26a as described above.

  In this case, the work instruction is selected according to the contents registered in advance in the assigned berth registration means 25, for example, the work of the berth 3 at a close position. In the registration example of FIG. 3, worker 8 with worker code 001 is instructed to work on berths with berth numbers 1-4, and worker 8 with worker code 002 is instructed to work on berths 3 with berth numbers 3-6. . Therefore, each worker 8 needs to move within a limited range, and it does not take time to move from the current position to the berth 3 where the work is instructed. Therefore, the waste time of movement is shortened. In addition, when registering the berth 3 in charge, by registering according to the skill level of the worker 8 and the frequency of work occurrence by the berth 3, the difference in skill level among the workers 8, Efficient work can be performed by reducing waste due to differences in work occurrence frequency and uneven work waiting status. As a result, the operator 8 can be minimized.

In addition, when the work instruction request is made when there are work waiting in a plurality of berths 3, the work instruction unit 26 transmits the work instruction according to the priority set in the work priority setting unit 27. . Therefore, by setting an appropriate priority in the work priority setting means 27, the berth 3 to be worked on earlier or the berth 3 suitable for the worker 8 to work is designated. Thus, the work efficiency can be further improved.
Furthermore, when there is a plurality of works for which the worker 8 is in charge when the work instruction request is made, the work instruction means 26 instructs the assigned work in the registered priority order. Therefore, work instructions suitable for each worker 8 can be performed, and work efficiency can be further improved.
