Another of the at least two pick-and-place container devices is configured to pick up and place a second target container at the carrier docking area into a container position thereon, and move with the moving device to the second work area 12 to pick up and place the second target container at the container position into the second work area 12.

Based on the structure, the loading and unloading process of the warehousing system comprises the following steps:

the moving device drives at least two container picking and placing devices to the first working area 11, wherein one container picking and placing device picks up the first target container in the first working area 11 and places the first target container in a container position (a material taking part of a loading process).

The moving device drives at least two container taking and placing devices and the first target container to move to the carrier 2 of the carrier parking area 13, the other container taking and placing device takes out the second target container on the carrier 2 and places the second target container on the container position (material taking part in the blanking process), and the container taking and placing device on which the first target container is placed on the container position takes out the first target container and then places the first target container on the carrier 2 (material placing part in the loading process).

Then, the moving device continuously drives at least two container taking and placing devices and a second target container to move to a second working area 12, and the container taking and placing device on which the second target container is placed places the second target container in the second working area 12 (a material placing part in a material placing process).

Therefore, the container taking and placing mechanism provided by the present disclosure passes through at least two container positions, and when loading and unloading are performed, after the container is brought to the carrier 2 by the moving device, the first target container and the second target container located on the carrier 2 are exchanged by using the at least two container positions, and then the container is directly returned to the second working area 12 for unloading.

Obviously, compare with the unloading process of current warehouse system, the blowing of the warehouse system material loading process of this disclosure and the material of unloading process are all accomplished at same target location of same carrier 2, save to get the step that container mechanism 3 moved between two carriers or the different storage positions of same carrier, have saved the time, have improved unloading efficiency on going up.

In addition, an idle storage position is not required to be reserved on the carrier 2 to accommodate the first target container needing to be fed, and an idle storage space generated after feeding operation does not exist on the carrier 2 after feeding is completed, so that the utilization rate of the storage space of the carrier 2 is improved to a certain extent.

It should be noted that the container taking and placing mechanism 3 of the present disclosure is mainly used for performing a loading and unloading task of a container, that is, taking out a first target container located at a first target position of a loading point, and then transporting the first target container to a carrier, placing the first target container at the target position on the carrier 2, and taking out a second target container on the carrier 2, then transporting the second target container to a unloading point, and then placing the second target container in the target position of the unloading point. Of course, the container taking and placing mechanism is not limited to the task of loading and unloading the container, and those skilled in the art can be used to implement other tasks based on the structure and working principle of the mechanism.

With continued reference to fig. 2 and 3, the motion apparatus of the present disclosure includes a robotic arm 30, which robotic arm 30 is movable between different positions based on received instructions, in turn achieving the purpose of handling containers. It can be understood that the moving device is not limited to the mechanical arm, and may be other mechanisms based on the moving function of the container handling device combined with the mechanical arm to handle the container at different target positions according to the received control instruction, for example, the moving device may be an automatic navigation transport vehicle such as a forklift robot.

The moving device further includes at least two trays disposed on the robot arm 30, and a container taking and placing device is disposed on any one of the at least two trays.

In addition, the trays may be arranged at the same level as shown in fig. 3, or may be arranged at different levels, as long as it is ensured that the containers can be taken out of or put into their container positions by the container pick and place device on the tray.

In order to make the structure of the container taking and placing mechanism more compact, according to one embodiment of the present disclosure, the container taking and placing device and the trays in the present disclosure are arranged in a matching manner, that is, one container taking and placing device is configured on each tray.

The specific structure and operation principle of the container picking and placing device disposed on the first tray 31 will be described in detail below, and the specific structure and operation principle of the container picking and placing device disposed on the second tray 32 are the same, and will not be described again.

In detail, the pick-and-place container apparatus of the present disclosure includes a conveyor belt 33 and a conveying driving element.

Wherein the conveyor belt 33 is movably conveyably provided on the first tray 31, and an upper surface of the conveyor belt 33 forms a container position. In this way, the first target container or the second target container is placed on the container position of the conveyor belt 33, and the conveyor belt 33 moves relative to the first tray 31 to drive the first target container or the second target container to move along the moving direction of the conveyor belt 33 relative to the first tray 31. Also, the assembly of both the second tray 32 and the conveyor belt 33 is the same as that of the first tray 31 and the conveyor belt thereof, and can be fully realized by those skilled in the art based on the above description, and thus, the detailed description thereof is omitted herein.

The transport drive element is configured for driving the transport belt 33 to forward or reverse with respect to the first tray 31 to bring the first or second target container into or out of the corresponding container position.

In detail, the moving device drives the first tray 31 to move to a first target position of the feeding point, the conveying driving element on the first tray 31 drives the conveying belt 33 to rotate forwards, the first target container on the first target position is pushed to a part of the first target container to enter the conveying belt 33 by the worker, the first target container is conveyed to the central area of the container position by the conveying belt 33 as the conveying belt 33 continues to rotate, the conveying driving element is closed, and the conveying belt 33 stops rotating.

The moving device drives the second tray 32 to move to a second target position on the carrier, the conveying driving element on the second tray 32 drives the conveyor belt to rotate reversely, a second target container at the second target position on the carrier is pushed to a part of the second target container to enter the conveyor belt by a worker, the first target container is conveyed to the central area of the container position by the conveyor belt along with the continuous rotation of the conveyor belt, the conveying driving element is closed, and the conveyor belt stops rotating.

The moving device drives the first tray 31 with the first target container temporarily stored to move to the second target position of the carrier again, the conveying driving element on the first tray 31 drives the conveyor belt 33 to rotate reversely, the conveyor belt 33 conveys the first target container away from the first tray gradually until the first target container completely enters the second target position on the carrier 2, the conveying driving element is closed, and the conveyor belt 33 stops rotating.

The moving device drives the second tray 32 with the second target container temporarily stored to move to a third target position of the discharging point again, the conveying driving element on the second tray 32 drives the conveying belt 33 to rotate reversely, the conveying belt 33 conveys the first target container away from the second tray 32 gradually until the first target container completely enters the third target position, the conveying driving element is closed, and the conveying belt 33 stops rotating, so that a feeding and discharging task is completed.

That is, the conveyance driving element is configured to drive the conveyance belt 33 to rotate. The conveying drive unit can drive the conveyor belt 33 to rotate, so that the container outside the container position can be brought into the container position by the conveyor belt 33, and the container inside the container position can be taken out of the container position by the conveyor belt 33. In particular, the conveyor drive element can bring the containers into and out of the container position by adjusting the direction of rotation of the conveyor belt.

According to one embodiment of the present disclosure, a transmission drive element of the present disclosure includes a driving timing pulley, a driven timing pulley, and a transmission motor. Wherein, driving synchronous pulley and driven synchronous pulley are all installed on the tray with rotatable mode, and the conveyer belt 33 tensioning is installed on driving synchronous pulley and driven synchronous pulley, and the conveying motor is connected with driving synchronous pulley transmission.

After the transmission motor is started, the driving synchronous pulley drives the driven synchronous pulley to rotate, and then the transmission belt 33 is driven to rotate. Changing the direction of rotation of the conveyor motor changes the direction of rotation of the conveyor belt 33.

Compared with other devices, the process of bringing the container into or out of the container position by using the conveyor belt 33 is more stable, the conveyor belt has a certain buffering and vibration absorbing function, and the whole transmission structure is simpler and is convenient to maintain.

Further, as mentioned above, when the container taking and placing device takes out the first target container from the first target position in the first working area 11, the worker is required to exert an external force on the first target container to push the first target container, so as to ensure that at least a part of the first target container enters the conveyor belt 33 on the corresponding tray. Therefore, the conveyor belt 33 can drive the first target container to move to the center of the container position along with the first target container, and the addition of manpower increases the operation cost of the container taking and placing mechanism.

To this end, according to one embodiment of the present disclosure, the pick-and-place container apparatus of the present disclosure further comprises an auxiliary push-pull assembly disposed on the tray and configured to assist the conveyor belt in pushing or pulling the first target container or the second target container at least partially into or out of the respective container position.

Specifically, when the first tray 31 of the container picking and placing device reaches the first target position of the first working area 11, the auxiliary push-pull assembly at least partially pulls the first target container at the first target position onto the first tray 31, and the first target container is completely brought into the central area of the container position by the friction force generated by the rotation of the conveyor belt 33. Conversely, when the first tray 31 of the container taking and placing device moves to the second target position which is idle on the carrier, the conveyor belt 33 on the first tray 31 conveys the first target container to the second target position, and when the friction force between the second target container and the conveyor belt 33 is not enough to push the second target container into the second target position completely, the auxiliary push-pull assembly works to push the second target container into the second target position completely.

Similarly, when the second tray 32 of the container pick-and-place device reaches the second target position, the auxiliary push-pull assembly pulls the second target container on the second target position of the carrier at least partially into the second tray 32, and the second target container is completely brought into the central area of the container position by the friction force generated by the rotation of the upper conveyor belt.
