These are automated warehouse racks/systems with some sort of “Picking Systems” option, but are served as a separate system.
When using the light selection system (pickby-light), the warehouse is equipped with special shelf racks that are replenished from the back side, and on the front side they are equipped with a special display with buttons for correcting and confirming the set, as well as a light bulb that lights up if it is necessary to select goods from this shelf. The system operates as follows. The compositor scans the barcode of the tray that has arrived along the conveyor, finds the displays on the cells that are lit up, and makes a set of goods from these cells in accordance with the quantity indicated on the display.In this case, the set of goods should be carried out only from cells with a lit display. Then you need to confirm the set of goods at this address by pressing the button to the right of the display. After completing the selection of goods in this section, the compositor places the tray on a moving conveyor, along which it moves to the next desired sections. If the balance of goods in the cell does not correspond to the quantity being dialed, the quantity of goods that is in this cell is selected, and the value on the display is corrected according to the fact of the quantity dialed using the correction buttons. If the product is not in the cell, then it is necessary to correct the value on the display to “0”.
These systems provide a high speed of order picking, as the human eye quickly responds to a light signal.
Pick by Voice
The task of the technology is to free the hands and eyes of warehouse operators from most of the work with the mobile terminal. Instead of text on the terminal screen, the operator receives voice messages from the warehouse management system (WMS).
Reduce order picking time.
Reduce the number of errors in order picking.
Reduce the amount of paper documentation in the warehouse.
Increase the efficiency of warehouse staff.
Track inventory errors promptly.
Increase the productivity and throughput of the warehouse.
Raise the level of service quality.
The principle of operation of shaft-type machines is as follows: they first take piece products into channels, and then “shoot” them in accordance with the requirements of the order onto a conveyor belt, through which they fall directly into a tray or box to collect a specific order. Since these machines can simultaneously dispense products of different types, their productivity can reach up to 12,000 units per hour. In addition, this equipment provides maximum accuracy in the selection of orders with a minimum time for their execution.
AGV robot cart is an automatically controlled carrier with an electric motor that moves goods along a predetermined route, built in advance by the IT system. Due to the fact that the platform is autonomous. It does not require a person to manage it. The AGV is equipped with the sensors and sensors necessary for navigation to ensure safe movement. AGV is used in places where there are many workers, as well as in sites with unsafe environments for humans.
AGV is divided into types and can act as a towing vehicle that hooks auxiliary carts with cargo (parts) and transports them. AGV can lift mobile racks or trolleys on itself by driving under them. Depending on the requirements of the client, different types of AGVs are selected, as well as various behavior patterns are programmed.
Carousel picking systems
In the carousel system of automated selection of orders, the principle of “goods to person” is implemented. All goods are in special multifunctional trays moving along a closed circular path. When selecting an order, the desired tray is removed and placed on a conveyor that delivers the trays to the compositor’s workplace. The ordering principle is as follows. Suitable tray. Above the box where you want to put the goods from this tray, the number of packages for selection lights up. The typesetter takes out the required number of packages from the tray, places them in the appropriate box and confirms the set with a certain button.
Then the tray moves along the conveyor to be placed back on the “carousel”. At the same time, if there is not enough goods in the tray to complete the order, the compositor selects the goods and adjusts the number of positions on the display using the corresponding button.
Carousel systems have a number of advantages compared to other types of equipment:
• save up to 60% of the area required for storage of goods in racking, due to the compact arrangement of trays and
use of the entire height of the building;
• reduce picking time due to the lack of movement of goods from the storage area to the order picking area;
• minimize the time to search for goods, as there is an automatic movement of the tray with the desired goods to the picker’s workplace;
• protect cargo from unauthorized access.
Conveyor systems are effectively used as a link between different order picking areas, significantly reducing order picking time.
Often, the movement of goods from a high-rise warehouse to a retail site becomes a “bottleneck”, due to which stocks of goods in the picking area may not be replenished in a timely manner.
This situation leads to incomplete fulfillment of the customer’s order, despite the availability of goods in the warehouse. Installing a pallet conveyor between the high-rise storage area and the replenishment area of the picking area eliminates the problem. The average capacity of such a conveyor is 200 pallets per hour. This significantly reduces the time required for this operation, and the labor costs of personnel involved in the movement of goods from the main storage to the retail site of the set.
The movement of goods from the replenishment area of the picking zone directly to the cells from which selection is made for orders is also more rational to be carried out using conveyor technology. A warehouse worker transfers goods from a box to a tray corresponding to a specific picking area. In this case, after scanning the barcode of the tray and the box, a specific product name is bound to this tray.
This tray also moves along the conveyor, controlled by the information system, to the desired picking area, where the replenishment of the stock of goods takes place.
