BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a picking trolley for taking out articles stored in storage shelves by a required (shipping) number, placing them in a collection case (bucket), and moving in a collection area. The present invention relates to a picking cart that prevents sorting errors at the sorting frontage during picking work.

[0002]

2. Description of the Related Art Various types of articles are stored in a collection area, and taking out an article from a storage shelf is called picking. For example, the worker puts a collection bucket for each customer, such as a store, on a picking trolley, and removes the required (shipping) number of articles from the storage shelf based on the article order (shipping instruction) while moving the picking trolley. Perform picking work. Normally, after the work, there are a packing and packaging operation in which transport packaging (packing in containers) is performed for each order (shipping) destination, and a sorting operation in which the destinations are sorted into shipping destinations so that they can be easily loaded into transport vehicles. Accompanied.

In recent years, in picking work, shipping information for each customer, such as a store, is transmitted wirelessly from a host computer provided at a distribution center or the like, received by a terminal mounted on a picking trolley, and transmitted to a terminal. There is a method in which shipping information is displayed, and an operator picks up an article from a storage shelf and stores it in a collection bucket while moving a picking cart based on the shipping information displayed on the terminal.
Further, shipping information is displayed on a terminal of a picking cart, and it is displayed that which item and how many items should be picked for each customer, and a picking method of picking according to the instruction is performed. For example, 5 items for store A
When it is displayed that three items should be picked for the B store and two items should be picked for the C store, the operator picks 10 items in total as instructed, inspects them through a bar code scanner, etc., and picks up the picking cart. Put it on the temporary table above. Five are displayed in the collection bucket of store A, and after five are inserted and the completion button is pressed, three are displayed next in the collection bucket of store B. After performing the same operation, finally, two items are displayed in the collection bucket of the store C. As described above, the picking operation is performed by the picking cart. At the time of the picking operation, three mistakes, namely, an article error, a quantity error, and a sorting error occur. An article error and a quantity error are eliminated by passing through a barcode scanner, and a quantity error is eliminated by passing a barcode scanner one by one when products are put into each sorting frontage.

FIG. 6 is a perspective view of a conventional picking cart. In the figure, a is a picking cart. Reference numeral b denotes a caster provided on the lower surface of the bottom of the picking cart a. c
Are two portal frames erected on the picking cart a. Reference numeral d denotes a horizontal frame connecting the middle portions of the two portal frames c in the height direction, and constitutes a storage shelf on which the article storage bucket h is placed.
