The communication module is preferably a wireless communication module, such as a bluetooth communication module, etc., and performs wireless communication with the second warehouse management system to obtain the commodity information to be picked, including the commodity name, quantity, location, etc., and the automatic picking vehicle 100b picking commodity information. travel route. The driving module includes a plurality of drivers, such as a first driver for driving the vehicle body 10b to travel, a second driver for driving the picking basket 20b to move, and a third driver for driving the mechanical gripper 30b to extend and retract. Each driver is preferably a motor, an air cylinder, etc., which can be directly connected with the vehicle body 10b/picking basket 20b/mechanical gripper 30b, etc., or can be connected through a transmission element, such as a gear mechanism. The control module generates corresponding control signals according to the information received by the communication module, starts the corresponding drivers, and controls the operation of the entire automatic picking vehicle 100b to realize automatic picking.

The vehicle body 10b, as the base of the entire automatic picking vehicle 100b, can travel between the shelves 200b of the store warehouse according to the travel route given by the second warehouse management system. In some embodiments, a track is formed on the ground of the store warehouse to guide the traveling of the vehicle body 10b, and a groove 12b is formed in the center of the bottom of the vehicle body 10b to match the track on the ground. In some embodiments, the automated picking vehicle 100b may also be an autonomously navigated trackless handling robot.

When the first driver is activated, the vehicle body 10b is driven to travel along the planned route to the corresponding position of the shelf 200b where the commodities to be picked are stored. After that, the second drive is activated, and the mechanical gripper 30b is extended, so that the commodity to be picked falls into the picking basket 20b, and the picking of the commodity is completed. When multiple commodities are ordered in a consumer order, after the selection of a certain commodity is completed, the first drive starts again, and drives the vehicle body 10b to the corresponding position of the shelf 200b where the next selected commodity is stored according to the travel route, And repeat the above-mentioned picking process until all the commodities in the consumer's order have been picked.

In the embodiment shown in FIG. 10 , a vertical guide rod 14b is provided on one side of the vehicle body 10b. Taking the traveling direction of the picking cart 100b as the front-rear direction (ie, the X direction shown in the figure), the guide bar 14b is provided on the front side of the vehicle body 10b, and the picking basket 20b is located on the rear side of the guide bar 14b. A sleeve portion 22b is formed on the front side of the picking basket 20b, and the sleeve portion 22b is slidably sleeved with the guide rod 14b. The second drive includes a longitudinal drive, so that the picking basket 20b can slide up and down along the guide bar 14b (ie, the Z direction in the figure) under the driving of the second drive, and the height of the picking basket 20b can be adjusted to match the order to be picked. The heights of the bays where the merchandise is stored on the shelf 200b are matched. As shown in FIG. 13, in another embodiment of the present invention, a guide rod 14b is respectively provided on the front and rear sides of the vehicle body 10b, and a socket 22b and two guide rods are respectively formed on the front and rear sides of the picking basket 20b 14b are slidably connected to each other to form a more stable support for the picking basket 20b, and avoid problems such as unstable center of gravity caused by overweight commodities.

The picking basket 20b includes an outer frame 24b and a basket slidably connected to the outer frame 24b, the basket includes a first basket 26b and a second basket 28b. The outer frame 24b is a vertically arranged frame structure, the socket portion 22b is formed on the side of the outer frame 24b, the first cargo basket 26b and the second cargo basket 28b are arranged up and down and can be relative to the outer frame 24b along the left-right direction (that is, the Y direction shown in the figure) slides and protrudes outward. When the first basket 26b/the second basket 28b slides outward relative to the outer frame 24b and extends toward the shelf 200b, the picking position is reached; when the first basket 26b/the second basket 28b slides in the opposite direction and retracts When returning to the outer frame 24b, it is in the non-picking position. The sliding of the first cargo basket 26b and the second cargo basket 28b can be driven by two cargo basket drivers of the drive module, respectively. For example, the second driver also includes a lateral driver, and the lateral drivers can be two, respectively driving the first cargo basket 26b and Lateral sliding of the second cargo basket 28b. In some embodiments, the first and second baskets 26b and 28b can also be driven by the same basket drive, ie, the first and second baskets 26b and 28b are driven by the same lateral drive; alternatively, the first basket 26 And the second cargo basket 28 can also be driven by the second drive, without the need to configure the drive separately.

In other embodiments, only one or more than two cargo baskets may be provided.

In a specific embodiment, as shown in FIG. 10 , the first cargo basket 26b extends outward in a first direction (eg, leftward) relative to the outer frame 24b to reach the picking position, and relative to the outer frame 24bb along an opposite second direction. Slide in two directions (eg to the right) to retract into the outer frame 24b; the second cargo basket 28b slides to the right relative to the outer frame 24b to extend out of the outer frame 24b to the picking position, and slide to the left relative to the outer frame 24b to retract back into the outer frame 24b. In this way, when the automatic picking vehicle 100b of the present invention travels between the two rows of shelves 200b, the commodities on the left shelf 200b are received by the first basket 26b, and the commodities on the right shelf 200b are received by the second basket 28b. That is to say, the automatic picking vehicle 100b of the present invention can pick the commodities on the two rows of shelves 200b during one journey, and relatively, the speed of picking commodities can be nearly doubled.

In some embodiments, the first cargo basket 26b and the second cargo basket 28b can slide in two directions relative to the outer frame 24b to extend outward, that is, they can slide to the left to extend the outer frame 24b, or they can slide to the right to extend out of the outer frame 24b, so that the protruding direction of the first cargo basket 26b and/or the second cargo basket 28b can be selected according to the position of the commodities to be picked, so that the quantity of commodities received in the two cargo baskets 26b and 28b is approximately the same, ensuring that the two cargo baskets The baskets 26b, 28b can be fully utilized. In some embodiments, if the quantity of goods ordered by the same consumer order exceeds the upper limit that the two baskets 26b and 28b can carry at one time, the second warehouse management system may pre-divide the consumer order into multiple orders. Each of the sub-orders is correspondingly allocated to the plurality of automatic picking vehicles 100b to ensure that the commodities to be picked by each automatic picking vehicle 100b are within its carrying range.

The commodity storage information recorded by the second warehouse management system is specific to the subspace 31a of the turnover box 1a, for example, the commodity No. 1 is stored in the No. 1 sub-box 1-3 of the No. 3 turnover box in the A3 column of the A rack. No. 2 sub-space, No. 2 product is stored in No. 1 turnover box No. 1 sub-box No. 1-4 sub-space and No. 3 sub-box No. 1-2 sub-space, No. 3 product It is stored in the No. 1-4 sub-space of the No. 4 sub-box of the No. 1 turnover box in the B-5 column of the B-rack.

The turnover box 1a, the sub-box 30a, and the length of the sub-box 30a that need to be pulled out can be determined according to the type and quantity of the required commodities. For example, when you need to pick two No. 3 products, you need to pull out the No. 4 sub-box of the No. 1 turnover box by two spaces, that is, pull out the No. 1-2 sub-spaces of the No. 4 sub-box. For another example, when you need to pick 5 items of No. 2 product, you can extract all the No. 3 sub-boxes in the No. 1 turnover box and extract the No. 1-3 sub-spaces of the No. 2 sub-box; of course, you can also take the No. 1 turnover box at this time. The No. 2 sub-box of the box is all drawn out and the No. 3 sub-box is drawn out to one grid. The specific method to be adopted can be predetermined by the management system of the second warehouse according to an algorithm.

The invention also provides an automatic picking warehouse, which can automatically pick the commodities ordered by the consumers according to the orders of the consumers. In the embodiment shown in FIG. 14 and FIG. 15 , the automatic picking warehouse is the above-mentioned store warehouse.

As shown in FIG. 14 and FIG. 15 , the automatic picking warehouse includes a storage area I, a racking area II, a shipping area III, a turnover area IV, a recycling area V, and an automatic picking vehicle 100b passing between the areas I to V, The storage area I corresponds to the above-mentioned storage area 20 , the shelf area II and the recycling area V constitute the above-mentioned warehouse-in interaction area 22 , and the outgoing area III and the turnover area IV constitute the above-mentioned warehouse-out interaction area 24 . A large number of shelves 200b are placed in the storage area 1, and several turnover boxes 1a are stacked on each shelf 200b, and the commodities are stored in each turnover box 1a by portions. The ordered merchandise is picked from the corresponding tote 1a. After completing the picking of all the commodities of an order, the automatic picking vehicle 100b travels to the delivery area III, and the delivery staff picks up the ordered commodities from the delivery area III and delivers them to the consumers, and the entire order is completed.

The storage area I is located in the center of the warehouse, and the shelves 200b are arranged in rows in the storage area I. A passage is formed between two adjacent rows of the shelves 200b and at the side ends of each row of the shelves 200b for the automatic picking vehicle 100b to pass through to pick commodities. Preferably, a track is formed on the ground of the storage area I to guide the traveling of the automatic picking vehicle 100b. In the illustrated embodiment, each row of racks 200b is composed of two groups of racks 200b arranged back-to-back. The turnover boxes 1a on the two groups of racks 200b in the same row of racks 200b are oriented in opposite directions, and the turnover boxes 1a on each group of racks 200b are opened. The directions are all towards the adjacent channel. The above-mentioned arrangement of the shelves 200b can effectively reduce the floor space, optimize the picking path, and improve the picking efficiency.

The put-away area II is used for replenishment of the storage area I, and the delivery area III is used for the delivery of the picked goods. Preferably, the shelving area II and the shipping area III are located on opposite sides of the warehouse, so as to avoid interference between shipping and replenishment as much as possible. Preferably, there is an automatic loading truck in the racking area II, the supplemented goods are carried in the turnover box 1a and distributed to the warehouse by the central warehouse, and the automatic loading truck transports the supplemented turnover box 1a to the storage area I and is placed on the shelf. On the vacancy of 200b, automatic loading is realized. In the embodiment shown, the automatic pick-up truck of the put-away area II is implemented as an automatic pick-up truck 100b, that is to say, the automatic pick-up truck 100b has the functions of replenishing and picking order goods at the same time. The recycling area V and the shelf area II are located on the same side of the warehouse, and are used to store the empty turnover boxes 1a after shipment. The empty turnover box 1a is taken away and returned to the central warehouse. The empty turnover box 1a can be loaded with commodities again in the central warehouse to achieve the effect of recycling.

The shipping area III is preferably set up with multiple shipping windows, all commodities of the same order are sent to the same shipping window, and multiple shipping windows can realize the simultaneous shipment of multiple orders, and the delivery staff will deliver the goods according to the order. Pick up the ordered items at the window. In the present invention, the picked commodities are received in the cargo basket of the automatic picking vehicle 100b, and after the picking of an order of commodities is completed, the picked commodities and the cargo basket carrying the commodities are sent to the corresponding delivery window together. Turnover area IV and shipping area III are located on the same side of the warehouse. After the delivery staff takes the ordered goods in the basket at the corresponding shipping window, the basket is vacant and transferred to the turnover area IV for temporary storage, which can then be assembled again. The next picking operation is performed on the automatic picking truck 100, so that the basket can be recycled.

The management system of the warehouse receives the user's order and controls the operation of the automatic picking truck 100b according to the order to realize automatic picking. The relevant information of the commodities stored in the storage area I, including the name, quantity, stored shelf number and turnover box number of the commodities, etc., are recorded in the management system. When the consumer places an order for commodities, the management system compares the consumer's order information with the recorded commodity storage information, obtains the specific location of each commodity ordered by the consumer in the storage area 1, and plans the automatic picking vehicle 100b accordingly. travel route.

When the automatic picking warehouse receives an order from a consumer, the management system first determines the storage location of the ordered goods according to the order and plans the travel route of the automatic picking vehicle 100b; after that, the automatic picking vehicle 100b is on the ground of the warehouse according to the traveling route. Move and sequentially arrive at the corresponding position of the turnover box 1a where various commodities are stored. Please refer to FIG. 11 at the same time, after reaching the corresponding position of the turnover box 1a where the commodities to be picked are stored, first the picking basket 20b moves up and down as a whole to adjust the heights of the baskets 26b and 28b, and then the baskets 26b or 28b face the commodities to be picked. The side where the stored turnover box 1a is located extends outward. Finally, the mechanical gripper 30b pulls the sub-box 30a containing the commodities to be picked in the turnover box 1a to the top of the basket 26b or 28b, and the sub-box 30a is pulled. The items in the drawn one or more sub-spaces 31a are automatically dropped to the basket 26b or 28b.

Specifically, as shown in FIG. 11 , when the automatic picking truck 100b picks goods, first the vehicle body 10b is driven by the first driver to travel along the passage between the racks 200b, so that the picking basket 20b moves to the place to be picked. At the position corresponding to the turnover box 1a, the second driver drives the picking basket 20b to move to an appropriate position in the up-down direction according to the height of the turnover box 1a. When the turnover box 1a storing the commodities to be picked is on its left side, the first basket 26b is driven to extend leftward to the picking position; when the turnover box 1a storing the commodities to be picked is on its right side, the second cargo basket 26b is driven to the left to extend to the picking position; Basket 28b is driven to extend rightward to the picking position. Preferably, the protruding first cargo basket 26b/second cargo basket 28b is close to or in contact with the turnover box 1a to be picked, and the first cargo basket 26b/second cargo basket 28b and the The tote 1a of the goods is intended to be close to and below the tote 1a to be picked. The drawn length of the sub-box 30a depends on the position of the commodity to be picked in the sub-box 30a and the number of copies required for the commodity to be picked, which can be determined by the management system in advance. In addition, when the number of commodity parts to be picked exceeds the number of commodity parts stored in one sub-box 30a, a plurality of sub-boxes 30a can be drawn at the same time.

During picking, the mechanical gripper 30b extends outward under the action of the third drive, grabs the handle 70a on the sub-box 30a of the turnover box 1a to be picked, pulls out the sub-box 30a to a predetermined length, and is pulled out. The subspace 31a of the sub-box 30a is located just above the protruding first cargo basket 26b/second cargo basket 28b, so that the commodities just fall to the protruding first cargo basket 26b/second cargo basket 26b under the action of their own gravity in the cargo basket 28b. Preferably, the number of the mechanical grippers 30b is the same as that of the sub-boxes 30a of the turnover box 1a, and all the sub-boxes 30a of a turnover box 1a can be pulled simultaneously. Since the picking basket 20b is close to the turnover box 1a to be picked through the height adjustment, the distance that the goods fall is approximately the depth of the first basket 26b/the second basket 28b, so as to prevent the goods from falling to the picking basket 20b is damaged during the process to ensure the integrity of the product. In one embodiment, the mechanical gripper 30b can be extended in both directions to pull and pull the sub-boxes 30a of the turnover box 1a on the left and right sides, respectively. In this way, during the process of picking goods, the first basket 26b extends to the left while the second basket 28b extends to the right, and each mechanical gripper 30b simultaneously picks the two baskets 26b and 28b, which further improves the cost. The picking efficiency of the automatic picking cart 100b is invented.

Figure 11 shows that three sub-spaces 31a are drawn out, which means that the management system of the warehouse determines that it is necessary to pick 3 pieces of the commodity from the sub-box 30a. After the picking of the three shown commodities is completed, the mechanical gripper 30b pushes the extracted sub-box 30a back into the turnover box space 40a, and the automatic picking truck 100a travels to another turnover box 1a to continue picking or picking at a customer order. After completion, proceed to the outbound interactive area to unload the basket with the ordered goods for the deliveryman to pick up and deliver the goods. Similarly, in other embodiments, the number of sub-spaces to be drawn out of the sub-box 30a may also be other numbers according to the picking order and the state of the sub-box 30a.

After the automatic picking vehicle 100b completes the picking of all commodities in an order or a sub-order, the first drive is activated again, so that the automatic picking vehicle 100b travels to the outbound interaction area 24b of the warehouse outbound area III, where the outbound interaction area 24b The baskets 26b, 28 loaded with commodities are transferred to a predetermined shipping window, and automatic picking of commodities is completed. According to the order, the delivery person takes the corresponding product to the predetermined delivery window and delivers it to the consumer, and the entire order is completed. After the goods are taken away, the baskets 26b, 28b are returned to the empty state and transferred to the turnover area IV for temporary storage, and then reassembled on the automatic picking truck 100b for automatic picking of the next order.

Preferably, as shown in FIG. 12 , the top of the outer frame 24b of the picking basket 20b is provided with a turnover box bearing position 29b, and the turnover box bearing position 29b is located above the cargo baskets 26b and 28b. When all the commodities in a certain turnover box 1a are selected and empty, the automatic picking truck 100b can grab the empty turnover box 1a to the turnover box carrying position 29b, and the automatic picking truck 100b of the present invention can transport it to the warehouse of the warehouse. Recycling area V is stored for re-loading the goods to replenish the warehouse. Grabbing and recycling of the controlled turnover box 1a can be completed by the mechanical gripper 30b that pulls the sub-box 30a, or a turnover box gripper for grasping the turnover box 1a can be additionally configured on the automatic picking truck 100b.

According to the above description of the logistics warehousing system based on a turnover box, the present application also discloses an order execution method based on a turnover box. Regarding the structure and function of the logistics warehousing system, please refer to the detailed description of the foregoing embodiment.

As shown in Figure 16, the order execution method includes:

S910: According to the first order placed by each second warehouse to the first warehouse, allocate a plurality of turnover boxes in the first warehouse to accommodate the ordered commodities correspondingly to each second warehouse, and each turnover box only has accommodating the first order of goods in a single second warehouse;

S920: Establish second warehouse storage data for the turnover boxes from the first warehouse that are stored in the second warehouse and contain the ordered commodities; and

S930: According to the second order received by the second warehouse and the storage data of the second warehouse, select the commodity corresponding to the second order from the turnover box stored in the corresponding second warehouse.

As mentioned above, in the actual application scenario of the urban commodity logistics system, the first order may be an order placed by each store warehouse to the central warehouse, and the city central warehouse distributes goods for the corresponding store warehouse according to each first order; The order may be an order placed by an end consumer in the community to the store warehouse, and the ordered goods are delivered to the consumer from each store warehouse via, for example, a delivery man called a "rider".

Wherein each turnover box includes a turnover box space and one or more sub-boxes located in the turnover box space, each sub-box includes one or more sub-spaces, and the commodities corresponding to each second warehouse order are packaged by portions in a In or multiple subspaces of the turnover box, each subspace accommodates a commodity, and the commodity constitutes the minimum order unit of the commodity of the second order, and each subspace has a storage state and a picking state, Wherein, picking the commodity corresponding to the second order includes making one or more subspaces accommodating the commodity corresponding to the second order in a picking state.

In one embodiment, in the storage state, the bottom of each sub-space is in a blocking state; in the picking state, the bottom of one or more sub-spaces accommodating commodities ordered by consumers is in an open state to allow storage in the picking state. Items of a subspace drop from the bottom of the subspace.

In one embodiment, picking the commodity corresponding to the second order includes: according to the information of the commodity in the second order, moving one or more sub-boxes accommodating the commodity in the second order, so that the moved one or more sub-boxes are The one or more subspaces are located in a picking position where items within the one or more subspaces are dropped from their bottoms.

Referring to FIG. 11 at the same time, in one embodiment, picking the commodity corresponding to the second order includes:

The one or more sub-boxes 30a are extracted from the turnover box 1a by the automatic picking cart 100b, wherein the extraction distance of the one or more sub-boxes 30a is determined according to the number of items of the second order; and

The commodities in the one or more subspaces 31a are dropped from their bottoms into a picking basket 20b carried by the automatic picking vehicle 100b.

For example, if the quantity of a commodity in a consumer order is 3, as shown in FIG. 11 , three subspaces 31a are drawn out, and the 3 commodities are dropped into the picking basket 20b to complete the selection of the 3 ordered commodities .

For example, if the number of copies of a commodity in a consumer order is 7, as shown in FIG. 11, after or before three sub-spaces 31a are extracted, other sub-boxes 30a need to be extracted to select another four commodities.

In one embodiment, picking the commodity corresponding to the second order includes:

From the tote, the first sub-box 30a is withdrawn by a first predetermined distance such that one or more sub-spaces 40 of the first sub-box 30a are located at the picking position, the first predetermined distance according to the second The number of copies of the first item in the order's items is determined; and

From the tote 1a, the second sub-box 30a is withdrawn by a second predetermined distance such that one or more sub-spaces 31a of the second sub-box 30a are located at the picking position, the second predetermined distance according to the first The number of copies of the second product in the products of the second order is determined.

For example, if a consumer order contains 3 sets of the first product and 2 sets of the second product, the automatic picking truck 100b needs to extract the sub-box 30a containing the first product by a distance of 3 sub-spaces 31a, so that the products can be dropped Pick 3 first-type commodities by the way to the picking basket 20b, and the automatic picking vehicle 100b needs to extract the sub-box 30a containing the second-type commodity by a distance of 2 sub-spaces 31a, so that the commodities drop to the picking basket 20b Pick 2 of the second item. In this example, the first predetermined distance is the distance of 3 subspaces 31a, which corresponds to 3 copies of the first commodity in the order, and the second predetermined distance is the distance of 2 subspaces 31a, which corresponds to the 2nd item in the order. Two kinds of products correspond. In other embodiments, the number of subspaces 31a of the moving distance is not necessarily equal to the number of copies of the corresponding commodity, because the number of copies of one commodity in the order is large, and it may be necessary to pick from multiple sub-boxes 30a, or the selected sub-boxes 30a may need to be selected. The merchandise in the front one or more subspaces 31a of the box 30a has been picked in a previous picking operation. Therefore, a possible situation is that although a sub-box 30a is pulled out a distance of 3 sub-spaces 31a in one picking activity, only 1 item falls because the items in the previous two sub-spaces have been picked out before. .

Although the embodiment disclosed herein takes the commodity logistics system of the city as an example to introduce the present application, it should be understood that the logistics warehousing system of the present application can also be applied to other scenarios where one warehouse is required to distribute goods for multiple other warehouses .

In addition, although in the above-mentioned embodiment, the picking of the ordered goods is realized by the way that the goods are dropped from one or more subspaces, in other embodiments, the order goods can also be picked from the subspaces by the automatic picking cart. The top open grab is achieved. For example, the bottom of each subspace is in a closed state, so when the subspace is pulled out so that one or more subspaces are located in a picking position outside the turnover box space, the goods in the subspace will not fall, and the goods in the subspace will not drop. The gripper grabs the order item from the top opening of the subspace.

To sum up, this paper discloses a logistics warehousing system based on a turnover box, which uses the same turnover box in the first warehouse and a plurality of second warehouses for the turnover and picking of goods. Moreover, the turnover box has one or more sub-boxes, each sub-box includes one or more sub-spaces, the commodities corresponding to each order are packaged in one or more sub-spaces of the turnover box by portions, and each sub-space accommodates one or more sub-spaces of the turnover box. an item that constitutes the minimum order unit of an order item, each subspace has a storage state and a pick state in which items in one or more subspaces of the selected subbox are allowed to be pick. In some embodiments, in the picking state, the bottoms of one or more subspaces of the selected subbox are open to allow items contained in the subspaces to be dropped from the bottoms of the subspaces. By dividing the goods into the sub-spaces of the sub-boxes of the turnover box, and then realizing the order-goods picking by dropping the order goods from the bottom of the sub-space, the order-picking operation of the second warehouse will become more convenient and simplified. System algorithms to reduce hardware and software costs. In the above-mentioned first warehouse and second warehouse, commodities are stored and circulated in turnover boxes; in the distribution from the first warehouse to the second warehouse, they are also accommodated in weekly boxes for distribution; picking trucks pick When a consumer orders a product, the corresponding product is also picked from the turnover box in the second warehouse. Therefore, the first warehouse can complete the sorting of goods ordered by the second warehouse, and no goods sorting operation is required in the second warehouse, so that the second warehouse can be implemented as an unmanned warehouse, which reduces the probability of errors and improves the efficiency of background processing.

The concepts described herein may be embodied in other forms without departing from the spirit and characteristics thereof. The specific embodiments disclosed are to be regarded as illustrative and not restrictive. Accordingly, the scope of the invention is to be determined by the appended claims, rather than by the foregoing description. Any changes that come within the literal meaning and equivalency range of the claims are intended to fall within the scope of these claims.
