[0002]

[Prior Art]

 At a distribution center or the like, picking work is performed in which a fixed number of fixed types of products are picked up in accordance with a customer's order. Picking work is done in the original packaging or in individual units. When picking on a pallet in the original packaging unit, it can be automated to a considerable degree, but in the case of individual units, the range that can be automated is limited, and the merit of automation is also poor, so human Picking by is the mainstream.

[0003]

[Problems to be solved by the device]

 It is difficult to automate the picking work itself, which takes products out of shelves and stores them in buckets, but attempts have been made to automate the picking work allocation and inventory management at distribution centers. For example, there is a system that uses a picking cart that exchanges work data with a central control unit that performs allocation and management, and gives a work instruction to a worker on a liquid crystal screen. The worker inputs the picking cart, performs the displayed work, and when the work is completed, the central control unit is informed of the completion. In addition, a system has been put into practical use, in which a bucket equipped with an ID card that can be input / output to / from a central control unit is conveyed by a conveyor, stopped at a required location, and a product is stored from a shelf.

[0004] Such a picking cart and a picking system can automatically perform picking work and inventory management to improve the efficiency of delivery, but the equipment is expensive, and each picking cart and picking cart is provided for each worker. Preparing the units one by one or arranging the conveyors to accommodate a large number of items made the whole system considerably expensive.

Therefore, an object of the present invention is to provide a portable work instruction device capable of allocating picking work and managing inventory, and also enabling inexpensive manual picking.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention displays a storage means for storing the contents of a work input from a separate management means and a content of the work to be performed next from the stored contents of the work. A portable work instruction device having a display means for instructing the work and an input / output means for outputting the progress of the work to the management means and inputting the contents of the work from the management means is configured.

[0007]

[Action]

 Since the present invention has the above-mentioned configuration, it has the following effects.

In the portable work instruction device according to the present invention, a worker carries the portable work instruction device to perform work such as picking. First, the content of work is input from the separate management means to the portable work instruction device through the input / output means, and is stored in the storage means. The display means displays the contents of the work to be performed next from the stored contents of the work and gives an instruction, and the worker advances the work by referring to the display of the display means. The progress status of the work is output to the management means through the input / output means at any time or at an appropriate time (for example, from the storage means that stores the progress status after all the contents of the input work are performed). By exchanging data with the portable work instruction device, the management means can perform work allocation, inventory management, shelf management, etc., and manage the picking system.
