Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a picking cart for collecting articles on a collection shelf.

[Prior Art] In the process of distributing goods, a necessary number of required goods are collected from among a wide variety of goods and delivered to a destination.

Usually, such collection equipment is equipped with a plurality of collection shelves each having multiple stages of collection shelves, and a worker moves a picking trolley in front of each collection shelf (picking shelf) or between opposing mutually (picking aisles). While moving, the target items are taken out from the collection shelf and placed on a picking trolley to collect the items, and when the items on the collection shelf run out or become low, replenishment items are brought to the collection shelf using a forklift or the like. We are currently working to replenish the shelves.

In addition, the above-mentioned collection work is carried out by the worker moving the picking cart while looking at notes (slips). The lift worker constantly looks around between the collection shelves to find places that need replenishment and replenishes them, or the collection worker gives instructions using replenishment notes or calls out to them each time.

[Problems to be solved by the invention] However, in the above-mentioned conventional method, the worker collects items while looking at the slip, etc., so the small letters are difficult to see and the slip is dirty. There are also problems such as misreading and collecting the wrong items or losing the slip.

In addition, since the work of replenishing the shelves with goods is carried out by forklift workers and others who look around between the collection shelves, the work has to be done all the time, which is extremely difficult and inefficient. In addition, there have been problems such as the possibility of overlooking missing items. In addition, the method by which a collection worker gives instructions to a forkman or the like has the problem that it takes a long time to process the instructions by writing a memo, and even when calling out, it is difficult to follow the instructions or it is easy to make mistakes.

The present invention provides a picking trolley that can reliably convey instructions for picking items to a picking worker, and can also convey information such as replenishment of goods by the picking worker to the commanding party. The purpose is to improve work reliability and work efficiency.

[Means for Solving the Problems] The present invention has a trolley optical transmission device that performs transmission and reception by optical transmission with a fixed optical transmission device installed as appropriate, and the trolley is located within a transmission/reception area by optical transmission. Indicator lamp to notify you of the collection, collection display board to display the collection command, next work display board to display at least the next collection command, pick completion button to notify the completion of collection, replenishment of items, notification of missing items. This invention relates to a picking truck characterized by having a transmitting/receiving panel having a push button integrally mounted on the truck.

[Operation] When transmitting and receiving by optical transmission is performed after confirming whether the trolley is within the transmitting/receiving area using the indicator lamp, the collection command from the commanding side is sent to the transmitting/receiving board via the optical transmission device. The information is displayed on the product display board, and the product collection worker can accurately collect products according to the display.The product collection worker can also press a button to issue commands such as completing the picking task or requesting replenishment of the product. Furthermore, it becomes possible to immediately start preparing for the next collection operation after the current collection operation according to the display on the next operation display board.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 3 shows an example of a collection equipment to which the present invention is applied. In equipment in which a large number of collection shelves 1 are arranged in parallel, a picking trolley 3 The forklift passage 4 between the backs of the collection shelves 1 is used to collect the items on the collection shelves 1 according to a schedule while moving the items. A forklift 5 traveling there receives the articles from a primary storage area (for example, a three-dimensional automatic warehouse) 6 and replenishes them on a collection shelf 1 that is running low or out of stock.

As shown in FIG. 1, fixed optical transmission devices 8 connected to a command control device such as a control room (not shown) are installed at required intervals in the upper part of the picking passage 2, for example, on the ceiling 7, and each of the picking carts 3 is provided with a transmitting/receiving panel 9 capable of transmitting and receiving information to and from the fixed optical transmission device 8 and displaying information, a battery 10, and the like.

FIG. 2 shows an example of the transmitter/receiver board 9, which is equipped with a trolley optical transmission device 11 that performs optical transmission to and from the fixed optical transmission device 8, and a power switch 12 provided on the side. , a power indicator lamp 13, a charging lamp 14, and an OK lamp 15 and a buzzer 23 for indicating whether the picking cart 3 is within the optical transmission area.

Furthermore, the location, quantity, code,
A current collection display board 16 is provided that displays the current collection command such as product name on a liquid crystal display, and a display board 17 that displays the next location and quantity, and the next work display board 17 that displays the next location and quantity. are arranged side by side.

Furthermore, the current collection display board 16 has a return button 18 for displaying a previous command (previous collection command) to the currently displayed collection command so that the previous collection command can be confirmed. , has a pick completion button 19 for notifying that the items have been collected.

In addition, when the collection worker thinks that the required number of items on the collection shelf 1 is present, but there will be insufficient items at the next collection time, the replenishment button 20 is pressed to notify the need for replenishment. It is equipped with an out-of-stock button 21 that is pressed to notify the need for urgent replenishment when the required quantity of the item to be purchased is insufficient, and a help button 22 that is pressed to notify the collection worker when he/she requests help (support). ing.

When collecting items, turn on power switch 12.
By doing so, the power indicator lamp 13 lights up to indicate that the power has been turned on. Charging lamp 14
is normally off, but lights up when the voltage drops to the standard value to indicate that charging is required.

Further, the trolley optical transmission device 11 is connected to the fixed optical transmission device 8.
When the vehicle is within an area where optical space transmission is possible between the vehicle and the vehicle, the OK lamp 15 lights up to notify that it is OK to collect the product.

Normally, when performing optical space transmission, the optical transmission device 8,
The transmission angle range of 11 is relatively narrow, and therefore, in order to ensure reliable transmission, it is necessary to install a large number of fixed optical transmission devices 8 at narrow intervals, and the picking cart 3 must be installed even outside the collection area. Although there is a problem that the equipment cost is large as it needs to be installed in the driving range, the above-mentioned OK lamp 15 and buzzer 2
By being able to check the transmission status using 3, the equipment can be relatively simple and highly reliable transmission can be performed.

Currently, the collection display board 16 displays the collection instructions from the command and control device, so the collection worker moves the picking cart 3 to the displayed location and picks up the items with the displayed code. The displayed number is taken into the picking cart 3. When the above operation is completed, press the pick completion button 19, the pick completion button 19 lights up, and the information is transferred to the optical transmission device 11,
8 to the command control device, and the light is turned off upon completion of the transmission. Then, the next product collection instruction is displayed on the current product collection instruction board 16, and the product collection operation is performed in the same manner.

At this time, the next or next collection command is displayed on the next work display board 7, so the worker can immediately start preparing for the next collection work after the current collection work, and so on. It is possible to improve efficiency by setting up

In addition, if you are unsure whether the previous collection was completed correctly, press the return button 18, and the previous collection command will be displayed on the current collection display board 16 for as long as you press the return button 18. This allows confirmation to be made.
