Description

Technical Field

[0001] The utility model relates to the technical field of cargo storage, in particular to a rope-driven cargo storage and retrieval system. Background Art

[0002] The cargo storage and retrieval system is an integral part of logistics and warehouse management, and involves the automated or semi-automated management of cargo storage. This system is designed to improve the efficiency of warehouse operations, reduce manual errors, and optimize the use of storage space. The cargo storage and retrieval system enables fast and accurate slot positioning, taking goods out of the slot or putting goods into the slot, thus meeting the needs of modern logistics for high efficiency and accuracy.

[0003] In the prior art, patent CN 110171660 A discloses a cargo sorting system and cargo sorting method, which includes multi-layer shelves, a sorting device and a temporary storage bin. The sorting device is used to sort target goods from the multi-layer shelves under the control of a control system and transfer the target goods to the temporary storage bin. In this scheme, the sorting device is driven to each temporary storage bin by two horizontally arranged linear modules and a vertically arranged linear module. The stroke of the linear module is fixed and has no scalability. Therefore, when the storage demand increases, only additional linear modules can be customized or added, resulting in high use costs, and the above-mentioned linear modules have slow running speed and low storage and access efficiency. Summary of the invention

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a rope-driven cargo storage and retrieval system that is easy to expand and low in cost.

[0005] Technical solution: To achieve the above-mentioned purpose, the rope-driven cargo storage and retrieval system of the utility model comprises a shelf having multiple storage locations; the storage locations can store boxes or whole boxes of cargo filled with cargo, hereinafter referred to as cargo;

[0006] It also includes a pick-and-place mechanism and a driving system capable of driving the pick-and-place mechanism to reach each of the storage locations; the pick-and-place mechanism can take out goods from the storage locations and can store goods into the storage locations;

[0007] The driving system includes at least three groups of rope pulling devices, each of which has a rope that directly or indirectly acts on the pick-and-place mechanism, and the force application directions of each rope are different; it also includes a maintaining device for maintaining the posture of the pick-and-place mechanism.

[0008] Furthermore, the pick-and-place mechanism includes a suction cup mechanism and a conveyor belt mechanism; the suction cup mechanism can reciprocate and translate in the conveying direction of the conveyor belt mechanism. When picking up goods, the suction cup mechanism sucks the outer side of the goods, and then the suction cup mechanism retracts to pull the goods outward, so that the bottom surface of the goods contacts the conveyor belt mechanism, and the friction force of the conveyor belt mechanism causes the material box to continue to move outward until it is completely taken out. When putting the goods back, the conveyor belt mechanism transports the goods to the storage position, and in the second half of the transportation, the suction cup mechanism assists in pushing the goods completely into place.

[0009] Furthermore, the pick-and-place mechanism is a fork-type pick-and-place mechanism.

[0010] Furthermore, the maintenance device includes a guide unit capable of translating relative to the shelf along a first direction; the extension direction of the guide unit is not parallel to the first direction; and the pick-and-place mechanism can slide along the extension direction of the guide unit. Preferably, there are two guide units, which are disposed on both sides of the pick-and-place mechanism.

[0011] Furthermore, the first direction is a horizontal direction.

[0012] Furthermore, the rope pulling device also includes a reel for reeling in the rope and a drive motor connected to the reel. The drive motor can realize the reeling and releasing of the rope by driving the reel to rotate forward and reversely. The coordinated operation of multiple rope pulling devices can change the height and lateral position of the picking and releasing mechanism.

[0013] Furthermore, there are four groups of rope-pulling devices; relative to the storage area formed by all the storage positions on the shelf, the reeling wheels of the four groups of rope-pulling devices are respectively located at the four corners of the storage area; the ropes of all the rope-pulling devices are connected to the pick-and-place mechanism.

[0014] Furthermore, there are three groups of rope-pulling devices, one group of which is installed at one end of the guide unit and can move with the guide unit; the other two groups of rope-pulling devices are installed on the shelf, and both are located on both sides of the other end of the guide unit; the ropes of the three groups of rope-pulling devices are all connected to the pick-up and placement mechanism.

[0015] Beneficial effects: The rope-driven cargo storage and retrieval system of the utility model has the following beneficial effects:

[0016] (1) Multiple sets of rope pulling devices drive the pick-and-place mechanism to move horizontally and vertically through ropes. The rope pulling device is easy to install. Since it acts on the pick-and-place mechanism through soft ropes, there are few restrictions on its installation position, making the overall scalability of the cargo storage and retrieval system strong. When the length or height of the shelf needs to be increased or decreased, it only needs to reinstall the rope pulling device, which greatly improves the scalability of the system;

[0017] (2) The maintenance device can effectively maintain the posture of the pick-and-place mechanism to prevent the pick-and-place mechanism from shaking significantly when it moves at high speed. The guide unit of the maintenance mechanism is preferably moved laterally, so that when all the pull rope devices drive the pick-and-place mechanism to operate, in addition to the weight of the pick-and-place mechanism and the goods, there is basically no need to overcome additional forces. In the cargo storage and retrieval system, the moving parts are light in weight and flexible in movement, which makes it easy to achieve high-speed operation and improve efficiency.

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 The rope-driven cargo storage and retrieval system shown comprises a shelf 1 having multiple layers of storage positions 11; the storage positions 11 can store boxes or whole boxes of cargo filled with cargo, hereinafter referred to as cargo; it also comprises a pick-up and place mechanism 2 and a driving system capable of driving the pick-up and place mechanism 2 to reach each of the storage positions 11; the pick-up and place mechanism 2 can take out cargo from the storage positions 11 and can store cargo into the storage positions 11, and after taking out cargo from the storage positions 11, the pick-up and place mechanism 2 can transport the cargo to a preset position for handing over to other conveying devices, and the pick-up and place mechanism 2 can also obtain cargo from a cargo supply device arranged at a fixed position and move the cargo to the storage position 11 for storage; the driving system comprises at least three groups of rope pulling devices 3, each of the rope pulling devices 3 has a rope 31 that directly or indirectly acts on the pick-up and place mechanism 2, and the force direction of each rope 31 is different; the cargo storage and retrieval system also comprises a maintaining device 4 for maintaining the posture of the pick-up and place mechanism 2.

[0026] In the above storage and retrieval system, multiple groups of rope pulling devices 3 drive the pick-up and placement mechanism 2 to move horizontally and vertically through ropes 31. The rope pulling device 3 is easy to install. Since it acts on the pick-up and placement mechanism 2 through soft ropes 31, there are few restrictions on its installation position, which makes the overall expandability of the cargo storage and retrieval system strong. When the length or height of the shelf 1 needs to be increased or decreased, it is only necessary to reinstall the rope pulling device 3, which greatly improves the expandability of the system. The maintenance device 4 assists the pick-up and placement mechanism 2 to maintain its posture, prevents the pick-up and placement mechanism 2 from shaking, and maintains the stability of the system operation.

[0027] In one embodiment, if Figure 3 As shown, the pick-and-place mechanism 2 includes a suction cup mechanism 21 and a conveyor belt mechanism 22; the suction cup mechanism 21 can reciprocate and translate in the conveying direction of the conveyor belt mechanism 22. When picking up goods, the suction cup mechanism 21 sucks the outer side of the goods, and then the suction cup mechanism 21 retracts to pull the goods outward, so that the bottom surface of the goods contacts the conveyor belt mechanism 22, and the friction force of the conveyor belt mechanism 22 causes the material box to continue to move outward until it is completely taken out. When putting the goods back, the conveyor belt mechanism 22 transports the goods to the storage position 11. In the second half of the transportation, the suction cup mechanism 21 assists in pushing the goods completely into place.

[0028] In another embodiment, the pick-and-place mechanism 2 is a fork-type pick-and-place mechanism. The specific structure of the fork-type pick-and-place mechanism is shown in the prior art such as patent CN219173279U, and is not further introduced here.

[0029] The maintaining device 4 includes a guide unit 41 capable of translating along a first direction relative to the shelf 1; the extending direction of the guide unit 41 is not parallel to the first direction; the pick-and-place mechanism 2 can slide along the extending direction of the guide unit 41. Preferably, there are two guide units 41, which are disposed on both sides of the pick-and-place mechanism 2. By adopting such a maintaining device 4, the posture of the pick-and-place mechanism 2 can be effectively maintained, and the pick-and-place mechanism 2 can be prevented from shaking significantly when moving at high speed.

[0030] Preferably, the first direction is a horizontal direction. A transverse guide rail 42 is installed on the shelf 1 to guide the guide unit 41. In this way, when all the pull rope devices 3 drive the pick-up and placement mechanism 2 to operate, except for the weight of the pick-up and placement mechanism 2 and the goods, there is basically no need to overcome additional forces. In the cargo storage and retrieval system, the moving parts are light in weight and flexible in movement, and high-speed operation is easy to achieve, thereby improving efficiency.

[0031] like Figure 4As shown, the rope pulling device 3 also includes a reel 32 for reeling in the rope 31 and a driving motor 33 drivingly connected to the reel 32. The driving motor 33 can realize the reeling and releasing of the rope 31 by driving the reel 32 to rotate forward and reversely. The coordinated operation of multiple rope pulling devices 3 can change the height and lateral position of the picking and placing mechanism 2.

[0032] In the first embodiment, if Figure 1-2 As shown, there are four groups of the rope-pulling devices 3; relative to the storage area formed by all the storage positions 11 on the shelf 1, the winding wheels 32 of the four groups of the rope-pulling devices 3 are respectively located at the four corners of the storage area; the ropes 31 of all the rope-pulling devices 3 are connected to the picking and placing mechanism 2.

[0033] In the second embodiment, if Figure 5 As shown, there are three groups of the rope pulling devices 3, one of which is installed at one end of the guide unit 41 and can move with the guide unit 41; the other two groups of the rope pulling devices 3 are installed on the shelf 1, and both are located on both sides of the other end of the guide unit 41; the ropes 31 of the three groups of rope pulling devices 3 are all connected to the pick-and-place mechanism 2. With this structure, by installing one group of rope pulling devices 3 on the guide unit 41, the three groups of rope pulling devices 3 can be used to drive the pick-and-place mechanism 2 to rise and fall and move horizontally, which is more cost-effective.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
