Background technique

Shredded tobacco is formed after tobacco leaves are processed. Depending on the place of origin, the taste of tobacco is also very different. The shredded tobacco of finished cigarettes is mainly composed of shredded leaves, shredded stems and thin slices of shredded tobacco.

Cigarettes of different varieties and brands use different types of shredded tobacco. In the field of cigarette production and processing, the shredded tobacco needs to be stored.

The Chinese invention whose application publication number is CN102715651A discloses a method for storing tobacco leaves and shredded tobacco in a container-type storage cabinet. A track is laid between the silk-making line and the elevated warehouse, and a logistics vehicle is set on the track. The container-type storage cabinet is placed on the logistics vehicle. In the container-type storage cabinet, it is sealed, and then the container-type storage cabinet is transported to the elevated warehouse by the logistics vehicle for storage.

Using the shredded tobacco box to store shredded tobacco is more flexible, and it can be replaced quickly when the type of cigarette needs to be replaced. In order to prevent foreign matter from falling into the shredded tobacco box, it is necessary to add a cover to the shredded tobacco box, and when shredded tobacco is used, it is necessary to remove the cover from the shredded tobacco box.

The shredded tobacco boxes and stacks of box covers are stored in the elevated warehouse, and the stored shredded tobacco boxes are all equipped with box covers. When the shredded tobacco boxes need to be put into storage, they are first transferred to the transfer rail by the transfer vehicle, and the first sensor senses the shredded tobacco that needs to be put into the warehouse. Whether the box has a box cover, if there is a box cover, the control system instructs the stacker to transfer the shredded tobacco box into the high-rack warehouse; if there is no box cover, the control system instructs the manipulator to pick up the box cover from the buffer area, and the shredded tobacco box Cap operation.

If the first sensor senses that the shredded tobacco box that will enter the elevated warehouse does not have a lid, and the manipulator has just carried out the lid removal operation to another shredded tobacco box, then the manipulator can also directly add the picked up shredded tobacco box to the shredded tobacco box, and Case lids do not have to be picked up from the cache.

The second sensor is used to sense the number of lids in the buffer area. If the number of lids in the buffer area is less than the set value, the control system instructs the stacker to take out the lids from the elevated warehouse; if the number of lids in the buffer area is greater than If the set value is set, the control system instructs the stacker to put the cover of the buffer area into the high-bay warehouse.

When the control system instructs the manipulator to add and remove the lids, for the shredded tobacco boxes entering and leaving the elevated warehouse, the shredded tobacco boxes that arrive at the designated position first will be operated first, and the operation of removing the lids will be given priority.

In the busy state, ignore the lid near-full signal, and instruct the manipulator to fill up the lid stack in the lid buffer area if it is in the idle state; When the top sensor detects that the box cover is full, the control system instructs the stacker to move the box cover stack in the buffer area to the high-bay warehouse, and instructs the high-bay warehouse to allocate an empty pallet to the buffer area; When the second bottom sensor detects that the box cover will be used up, it will send a signal to the control system that the box cover will be used up, and the control system will determine whether the elevated warehouse is busy or idle according to the number of shredded tobacco boxes out of the warehouse within the current set time period , if it is in a busy state, ignore the signal that the lid will be exhausted, and if it is in an idle state, instruct the manipulator to clear the stack of lids in the lid buffer area; When the bottom sensor detects that the lid is empty, the control system instructs the stacker to store the empty pallets in the high-bay warehouse, and instructs the high-bay warehouse to allocate a pallet full of lids to the buffer area. 4. The shredded tobacco box when going in and out of the elevated warehouse as claimed in claim 3 adds and removes the cover method, it is characterized in that each manipulator corresponds to a fixed buffer area, and its maximum buffer capacity is 40 box covers, two dynamic buffer areas , respectively the first dynamic buffer area and the second dynamic buffer area, the maximum buffer capacity of each dynamic buffer area is 13 box covers; the control system controls the manipulator in the corresponding dynamic buffer area or fixed The buffer area picks and places the box cover. When the manipulator places the box cover to the buffer area, the specific process is as follows: If the number of box covers in the fixed buffer area is ≤25, place the box covers in the fixed buffer area; If the number of box covers in the fixed buffer area is > 25, the box covers are placed in the first dynamic buffer area. After the first dynamic buffer area is full, the box covers are placed in the second dynamic buffer area until the second dynamic buffer area. The box cover in the buffer area is full; If the number of lids in the fixed buffer area>25, and both the first dynamic buffer area and the second dynamic buffer area are full of lids, place the lids in the fixed buffer area; When the manipulator takes the box cover from the buffer area to cover the shredded tobacco box, the specific process is as follows: If the number of box covers in the fixed buffer area is ≥ 15, pick up the box covers from the fixed buffer area; If the number of lids in the fixed buffer area is <15, and the number of lids in the first dynamic buffer area is ≥ 4, pick up the lids from the first dynamic buffer area; when the number of lids in the first dynamic buffer area is <4 Pick up the box cover from the second dynamic buffer area; until the number of box covers in the second dynamic buffer area<4; If the number of lids in the fixed buffer area is <15, and the number of lids in the first dynamic buffer area and the second dynamic buffer area are both <4, the manipulator picks up the lid from the nearest dynamic buffer area that still has a lid; If both the first dynamic buffer area and the second dynamic buffer area are exhausted, pick up the case lid from the fixed buffer area.
