The first cell 100 is a preferred part cell, the second cell 200 is a preferred part cell, the first walking mechanism 400 is used for carrying the tray to move the object placed by the first user from the first cell 100 to the storage chamber near the second cell 200 for storage, and the second walking mechanism 500 is used for moving the tray without the object to the storage chamber near the first cell 100. If the first user uses the first grid 100 to dispatch the parts and the second user uses the second grid 200 to fetch the parts according to the suggestion, the walking distance of the first walking mechanism and the second walking mechanism 500 is very short, and the efficiency of dispatching and fetching the parts can be maximized.

In one embodiment, when the first and

second bays

100 and 200 are used simultaneously, the first and

second travel mechanisms

400 and 500 determine a travel plan with the least total travel distance, and dispatch and/or pickup are performed according to the travel plan. Specifically, when a first user sends a piece and a second user takes a piece, the piece sending and the piece taking can be completed according to the positions of the trays needed by the first user and the second user, if the current position of the first walking mechanism 400 is closer to the tray needed by the first user, namely the position of the empty tray, the empty tray is carried by the first walking mechanism 400 from the lattice used by the first user, the article placed by the first user is moved to the storage chamber to be stored so as to complete the piece sending, the tray needed by the second user is carried by the second walking mechanism 500, the article on the tray is moved to the lattice used by the second user, and the article is provided to the second user so as to complete the piece taking. If the current position of the first travel mechanism 400 is closer to the tray desired by the second user. Furthermore, the first walking mechanism or the second walking mechanism 500 can be selected to finish picking or dispatching according to the total walking distance of the first walking mechanism and the second walking mechanism 500, and the scheme with the minimum total walking distance is selected, so that the first user and the second user can finish dispatching and picking quickly.

For example, since the first user sends the item using the second bay 200 and the second user takes the item using the first bay 100, the item previously sent by the first user is placed in the tray of the storage room close to the second bay 200, the item required by the second user is close to the second bay 200, and the empty tray required by the first user is close to the first bay 100, if the first and second traveling mechanisms 500 are located close to the first and

second bays

100 and 200, respectively, and the sending and taking of the item directly by the first and second traveling mechanisms 500 consumes a lot of time and electric power, it is possible to exchange the tray and return the tray to the original position by the tray exchanging mechanism 600, so that a lot of time and electric power can be saved.

In one embodiment, the first traveling mechanism has a traveling range in a region near the first cell 100, and the second traveling mechanism 500 has a traveling range in a region near the second cell 200, which are divided by the tray exchange mechanism 600, and each of the two regions occupies half of the entire storage mechanism 300. At this time, if the first user uses the second bay 200 to dispatch the item, and the empty tray is located close to the first bay 100, the first walking mechanism 400 is required to carry the empty tray to the tray exchanging mechanism 600, so that the second walking mechanism 500 continues to carry the empty tray to the second bay 200, so as to move the item placed by the first user to the storage chamber for storage, thereby completing dispatching the item.

EXAMPLE III

As shown in fig. 4, a third embodiment of the present invention provides a dispatch and dispatch method, where the dispatch and dispatch method provided by the third embodiment of the present invention is applied to the multi-gate smart bin provided by the first embodiment of the present invention, and the dispatch and dispatch method includes:

s110, judging whether the first user and/or the second user use the first lattice and the second lattice simultaneously or not.

And S120, if so, acquiring the position information of the storage chamber required by the first user and/or the second user.

And S130, generating a first walking track of the first walking mechanism and a second walking track of the second walking mechanism according to the position information.

And S140, judging whether the first walking track and the second walking track are overlapped or not.

And S150, if so, executing dispatching and/or picking according to the time sequence used by the first user and/or the second user.

Illustratively, when a first user uses a second cell to dispatch a part, a second user uses the first cell to fetch the part, position information of the storage room required by the first user and the second user is obtained, and a first walking track of the first walking mechanism and a second walking track of the second walking mechanism are generated according to the position information. Because the grids selected by the first user and the second user are not the priority grids, the needed storage chambers are far away from the used grids, the first walking track and the second walking track are easy to coincide, and when the coincidence is judged, the piece dispatching of the first user is executed first, and then the piece taking of the second user is executed. The second walking mechanism starts to walk and the second user takes the part as long as the first walking mechanism walks to the condition that the first walking track and the second walking track are not overlapped, namely the first walking mechanism does not influence each other.

Example four

And S240, judging whether the first walking track and the second walking track are overlapped or not.

And S250, if so, controlling the first walking mechanism or the second walking mechanism to carry the tray of the storage room required by the first user and/or the second user to the tray exchange mechanism so as to execute dispatching and/or picking.

In this embodiment, the multi-cell intelligent bin applied by the method includes the tray exchange mechanism, so that even when it is determined that the first walking track of the first walking mechanism coincides with the second walking track of the second walking mechanism, the dispatching and/or picking up of the packages can still be completed through the tray exchange mechanism, the walking scheme with the minimum total walking distance is executed, and the maximum efficiency of dispatching and picking up the packages is achieved.

Illustratively, when a first user uses a first cell to send a piece, the first user also uses a second cell to send the piece, position information of storage rooms required by two first users is obtained, and a first walking track of a first walking mechanism and a second walking track of a second walking mechanism are generated according to the position information. Because of two first users all need to send the piece, need empty tray, it has the coincidence to take place first walking orbit and second walking orbit very easily, when judging to have the coincidence, if the storing room that empty tray place all is located first check mouth department, then first running gear walks to the storing room and gets two empty trays, second running gear walks to tray exchange mechanism department and waits simultaneously, then first running gear passes through tray exchange mechanism with an empty tray and exchanges for second running gear, then first running gear walks to first check mouth, second running gear walks to second check mouth, accomplish two first users' group piece.
