The present invention relates to systems, devices, and methods for eCommerce and warehouse management that include sorting and shipping orders to customers.
It is known in the field of supply chains that running a distribution operation comes with several well-known challenges. There is technology available that can help address all these challenges.
In a simple pick and pack operation or in a highly automated distribution center, a Picking Wall or Put Wall can be used in eCommerce or retail operations and can be fairly economical. As a brief overview of the system, a Put Wall is basically a shelving system (dynamic or static) outfitted with put lights. Each shelf slot, box, or tote represents an order for an eCommerce customer or part of a store order in a retail operation. Totes are picked upstream, mainly batch picked, at active locations (pick modules or racks) and conveyed to the put wall area. Typically, products are picked off the shelf in bulk to fulfill orders, as a wave pick, then brought to the put wall for sortation
Ideally, using totes involves a conveyor, but if there is no automation, pick totes may be transported to the Put Wall. Goods are then scanned using a put-to-light system and sorted into the slots/totes/boxes assigned to the orders in the picklist assigned to the Put Wall. An order may include multiple items. Once an order is complete, as in most typical put-to-light systems, the light associated with the order lights up on the back side of the shelf where a packer retrieves the goods and packs it at a station. The packer then scans/acknowledges the light and ships the order. After the order has been shipped the light may blink and/or turn off.
Barcode scanners and lights are used to ensure accuracy as scanning the product identifies the order corresponding to the item and lights up an appropriate slot for placement. Shelving can be very easily reconfigured, even if the conveyor cannot, so that zones are adjusted to changing demand/number of employees. Put zones can also be turned off/on and multiple lights can be used so that multiple operators can operate in the same zone, e.g. each operator or sorter having an associated color of light. Shelf spacings can be adjusted to allow for larger/smaller product to be handled. This goes for hazardous, high value or other product that for other reasons needs to be segregated. Also, the system may assign a slot to a location near the employee to prevent multiple operators from bumping into each other.
A Put Wall area can be set up in several spots or in a large area which may be scalable for future growth and peak demand. Cycle times with put walls may be improved because of the ability to have multiple put walls operating simultaneously as it takes less time to get a large number of orders completed. Lastly, a Put Wall does not necessarily need conveyor or any type of specialized material handling equipment.
However, there may be a need for a customizable, simplified sorting and optimized fulfillment approach with streamlined picking, sorting, and shipping including scalable efficiency for eCommerce and warehouse management.

Referring specifically to
A plurality of shipper light boxes 14 (e.g. Shipper Box 1 through Shipper Box 50) are each configured to be coupled to a respective sorter light box 12 and positioned at the respective shelf. Each of the shipper light boxes 14 is configured to provide a light indication to the shipper indicating that an order is ready to be shipped. A respective sorter light box 12 and associated shipper light box 14 may define a sorting/shipping light box pair 15 as illustrated in
A concentrator or hub 16 is coupled to a first sorter light box 12 (e.g. Sorter 1) and operates as a concentrator of control signals and power for the plurality of sorter light boxes 12 in the chain. A first power supply 18 is configured to be coupled to the hub 16 and supply power to the sorter light boxes 12 and shipper light boxes 14. Additional power supplies, e.g. a second power supply 19 may be included within the chain and a repeater 22 is coupled within the chain to push power (e.g. from the second power supply 19) along the chain of sorter light boxes 12 and shipper light boxes 14.
A controller 20 is configured to be coupled to the hub 16 and generate the control signals for the sorter light boxes 12 in the chain, and the shipper light boxes 14, based upon commands received via an externally coupled network. The controller 20 may be configured to generate the control signals for the sorter light boxes 12 based upon commands received via the externally coupled network and sorter scans from a handheld or mobile device MD coupled thereto. The controller preferably includes a wireless communication interface to communicate with the externally coupled network. However, wired communication is also contemplated.
There are software components in the system 10 that may include: the hub software (e.g. web application) that is run on the controller 20 or a local computing device (e.g. a laptop or PC); a mobile application software that is run on a handheld or mobile device MD; and the firmware that resides on the four hardware devices (sorter light box 12, shipper light box 14, hub 16 and controller 20) described above and keeps everything communicating together.
Some additional features of the mobile sorter application may include, for example, providing suggestions as to what to sort next to complete slots that are in process, filtering the orders by a picklist so that the system assigns an order limited to the orders of the picklist, and/or a feature to accept a replacement item for an order.
The sorter light boxes 12 and shipper light boxes 14 may have the same design, for example, as illustrated in
Referring additionally to the schematic illustration in
Power over Ethernet, or PoE, is any of several standards or ad hoc systems that pass electric power along with data on twisted pair Ethernet cabling. This allows a single cable to provide both data connection and electric power to devices such as Wireless Access Points (WAPs), Internet Protocol (IP) cameras, and Voice over Internet Protocol (VoIP) phones.
There are several common techniques for transmitting PoE cabling. Three of them have been standardized by Institute of Electrical and Electronics Engineers (IEEE) standard IEEE 802.3 since 2003. These standards are known as Alternative A, alternative B, and 4PPoE. For 10BASE-T and 100BASE-TX, only two of the four signal pairs in typical Cat 5 cable are used, Alternative B separates the data and the power conductors, making troubleshooting easier. It also makes full use of all four twisted pairs in a typical Cat 5 cable. The positive voltage runs along pins 4 and 5, and the negative along pins 7 and 8.
Alternative A transports power on the same wires as data for 10 and 100 Mbit/s Ethernet variants. This is similar to the phantom power technique commonly used for powering condenser microphones. Power is transmitted on the data conductors by applying a common voltage to each pair. Because twisted-pair Ethernet uses differential signaling, this does not interfere with data transmission. The common-mode voltage is easily extracted using the center tap of the standard Ethernet pulse transformer. For Gigabit Ethernet and faster, both alternatives A and B transport power on wire pairs also used for data since all four pairs are used for data transmission at these speeds.
In addition to standardizing existing practice for spare-pair (Alternative B), common-mode data pair power (Alternative A) and 4-pair transmission (4PPoE), the IEEE PoE standards provide for signaling between the power sourcing equipment (PSE) and powered device (PD). This signaling allows the presence of a conformant device to be detected by the power source, and allows the device and source to negotiate the amount of power required or available.
As illustrated in the example embodiment of
After approximately sixteen to twenty-six sorter light boxes 12/14 in series (e.g. preferably twenty), for example, the repeater 22 may be added to the chain to push the power further along in the chain, for example, as it may be expanded to over one hundred light boxes. The hubs 16 and repeaters 22 may have the same design, as illustrated in
Thus, with the above described systems, devices and methods, a shipper may set, customize, and simply rearrange any style or design of a Picking Wall or Put Wall arrangement as needed. The present customizable item sorting system 10 (or light box system) may be thought of as a DIY system as far as how a user may set up the shelves, since the light boxes 12/14 may be mounted in any area, and the light boxes are not fixed or bunt into any shelving.
Some of the illustrative aspects of the present invention may be advantageous in solving the problems herein described and other problems not discussed which are discoverable by a skilled artisan.
