Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The examples in the embodiments are intended to be used for explaining the present application and are not to be construed as limiting the present application.

Reference in the specification to "one embodiment" or "an example" means that a particular feature, structure, or characteristic described in connection with the embodiment itself may be included in at least one embodiment disclosed herein. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

Examples: the present embodiment provides a buffer rack for a storage rack, as shown in fig. 3 and 4, the buffer rack includes a suspension beam 1, a suspension column 2, and a buffer support 3, wherein the suspension beam 1 is fixedly connected with the storage rack 4, the suspension column 2 is fixedly mounted on the suspension beam 1, and the buffer support 3 is fixedly mounted on the suspension column 2. In the embodiment, the suspension upright post 2 is in screw thread fastening connection with the suspension cross beam 1, and the buffer support piece 3 is also in screw thread fastening connection with the suspension upright post 2, so that the buffer support piece is conveniently separated into single parts during transportation, space occupation is reduced, and the buffer support piece is assembled on a use site. Alternatively, in different embodiments, the device can be designed as a detachable clamping and fixing connection mode; or the device is designed into a non-detachable fixed connection mode such as welding and the like, and is directly delivered in an integral mode. The buffer storage rack is fixedly arranged on the storage shelf through the hanging cross beam, and the negative influence on the passing of the ground robot under the storage shelf is avoided. Meanwhile, due to the fact that the hanging cross beam is arranged, the position selection of the hanging cross beam when the hanging cross beam is installed on the storage rack is more, and therefore the suitability of the buffer storage rack is better. When the hanging cross beam is fixedly arranged on the upright post of the storage shelf, the connecting strength is high in the state, and the weight of the bearable material box is larger.

In addition, in this embodiment, a plurality of groups of suspension columns 2 are disposed along the length direction of the suspension beam 1, and a space 30 is provided between the buffer supports 3 on two adjacent groups of suspension columns 2, and the space 30 can be used for passing through a jacking mechanism on a second transfer robot in the warehouse system, so that the transfer efficiency can be improved, and the operation principle of the jacking mechanism is described in a transfer box example mode. Along the length direction of the suspension cross beam 1, the buffer supporting pieces 3 on two adjacent groups of suspension upright posts 2 are matched to form a buffer position for the buffer bin.

The distance 30 is fixed in some alternative embodiments, i.e. the distance 30 is pre-dimensioned, and the distance 30 of corresponding dimensions is obtained after the assembly of the suspension cross member 1, the suspension upright 2 and the buffer support 3. In other alternative embodiments, the size of the space 30 may be adjusted, for example, the suspension upright 2 and the suspension beam 1 are fastened by using bolts, the buffer support 3 and the suspension upright 2 are also fastened by using bolts, a plurality of through holes (for allowing bolts to pass through) may be provided on the suspension beam 1 or the suspension upright 2 or the buffer support 3, and one of the through holes may be selected as a through hole for allowing a bolt to pass through during assembly, so that the size of the space 30 may be adjusted. Thus, when the storage rack is mounted on the storage rack, the distance 30 can be adjusted according to the volume of the target storage bin of the storage rack and the matched carrying robot.

In this embodiment, two suspension cross beams 1 are provided, and two adjacent suspension cross beams 1 are fixedly connected by a first connecting rod 10 disposed therebetween. The overall strength of the buffer storage rack can be further increased through the arrangement, the buffer storage rack can bear larger weight, and meanwhile stability is better. For the same purpose, the suspension columns 2 correspondingly arranged on the two adjacent suspension beams 1 are fixedly connected through the second connecting rods 20 arranged between the two suspension columns. The fixed connection of the first connecting rod 10 and the second connecting rod 20 may be screw connection or welding. In other alternative embodiments, the number of suspension beams may be one or more, and for reasons of increased strength, it is generally recommended to provide more than two. It will be appreciated that in different embodiments the first connecting rod may be provided separately or the second connecting rod may be provided separately.

As shown in fig. 4, taking a typical storage rack as an example, the storage rack 4 includes support columns 40, support beams 41 fixedly attached to the support columns 40 in multiple layers, and storage supports 42 fixedly attached to the support beams 41. In the embodiment, an individual storage shelf 4 is provided with four support columns 40, and a plurality of support beams 41 are fixedly arranged between two adjacent support columns 40 from top to bottom along the length direction of the storage shelf 4; a storage support 42 is fixedly mounted between every two opposite support beams 41 along the width direction of the storage shelf 4, and a storage position for storing the bin is formed by the storage support 42. For convenience of presentation, the storage shelf 4 in fig. 4 only shows two layers of storage bits, and the storage bits can be set to be more layers according to needs, and in practical situations, more than ten layers or even tens of layers can be achieved. When the warehouse system is built, a plurality of warehouse racks 4 can be arranged to form a plurality of rows of warehouse racks according to the requirement. In this embodiment, the buffer support 3 has a plate-like structure, and the storage support 42 has a frame structure formed by a plurality of rod-like structures, but in other embodiments, the buffer support may have a frame structure, or the storage support may have a plate-like structure; the frame structure may have other shapes such as a mesh shape. The buffer support and the storage support are generally made of metal materials such as aluminum alloy and stainless steel, and of course, the buffer support and the storage support can also be made of materials such as hard plastic, so that the strength of the bearing material box can be guaranteed.

In applying the buffer rack provided in this embodiment, the buffer rack 43 is fixedly mounted on the storage rack 4, specifically in this embodiment, the storage rack 4 further includes a connection beam 5, and the connection beam 5 is fixedly mounted between the two support columns 40, and the suspension cross beam 1 is fixedly connected with the connection beam 5. The mounting position of the buffer frame can be more flexible by fixedly arranging the connecting beam 5 on the supporting upright 40. Further, the suspension cross member 1 in the present embodiment has a connection structure for fixedly connecting with the connection beam 5, as shown in fig. 5, the connection structure has a first side wall section 11 formed by extending the suspension cross member 1 upward, a top wall section 12 formed by extending the first side wall section 11 horizontally, and a second side wall section 13 formed by extending the top wall section 12 downward, the first side wall section 11, the top wall section 12, and the second side wall section 13 form a clamping groove adapted to the connection beam 5, the connection structure is hung on the connection beam 5 through the clamping groove and the connection structure is fixedly connected with the connection beam 5 through a bolt thread. It will be readily appreciated that in other embodiments, the connection structure may be provided without the second side wall section, and the hooking to the connection beam may be achieved. The connecting structure is beneficial in that the assembling operation is convenient, and the stability is good.

In connection with the illustration in fig. 6, in a different embodiment, the connecting beam 5 can also be fixedly connected between two opposite support beams 41, in which case the height dimension of the first side wall section 11 can be adapted to have a set height dimension such that the suspension beam 1 is located below the storage support 42, i.e. the first side wall section 11 objectively plays a role in avoidance.

In addition, in other alternative embodiments, the suspension beam may be directly fixedly mounted to the support upright or the support beam by means of bolts or welding, without providing a connection beam. However, in this way, the buffer rack is required to have a suitable size, for example, when the buffer rack is configured in a double-row structure as shown in fig. 7, the two suspension beams 1 located on the outer sides can be matched in position with the support columns 40 or the support beams 41 on the corresponding sides, so that the aforementioned fixed installation can be achieved. It is easy to understand that the buffer rack may be further designed in the longitudinal direction, as shown in fig. 8, or two layers of buffer supports 3 may be provided on the suspension upright 2 in the vertical direction, and the number of buffer bits may be increased as required. Of course, the number of layers of the buffer support may be three or more, and in general, the number of layers of the buffer support may be selectively designed to be one layer, two layers or three layers, which is limited by the height that the jacking mechanism of the second handling robot can raise and the actual requirement of the warehouse system.

When the storage rack provided with the buffer rack according to the present embodiment is applied to a storage system, the storage system includes the storage rack, a first transfer robot (not shown in the figure) and a second transfer robot (not shown in the figure), wherein the first transfer robot is used for transferring the pick-and-place box between two storage supports 42 or between the buffer support 3 and the storage support 42, and the second transfer robot is used for transferring the pick-and-place box relative to the buffer support 3 (generally, transferring the pick-and-place box between the buffer support 3 and a manual transfer point). The first transfer robot in this embodiment may be a traction type or forklift type robot, which is matched with a lifting device to move up and down relative to the storage rack 4; the second transfer robot adopts a hidden jacking robot, and the hidden jacking robot jacks up a bin on a cache position and moves with the bin to realize transfer by running below the cache position through a jacking mechanism. The benefits of providing the gap on the cache shelf are described in detail below with reference to fig. 4 and 9, taking the actual handling process as an example:

in order to facilitate the passing of the first transfer robot and the second transfer robot, a third channel 44 is arranged between two adjacent rows of storage shelves 4 of the storage system, and both the first transfer robot and the second transfer robot can pass along the third channel 44. However, if both the first transfer robot and the second transfer robot can only pass through the third channel 44, one of them needs to wait for the other in a certain period of time, especially in a larger-scale warehouse system, the number of robots is very large, which can cause congestion and seriously affect the transfer efficiency. Therefore, in this embodiment, a second channel for the second transfer robot to pass along the length direction of the storage racks 4 is formed below each row of storage racks 4, that is, the height and width of the space below the buffer rack are required to be used for the second transfer robot to pass during design. The second channel can provide more passage path selections for the second transfer robot, so that the transfer efficiency is improved. In this embodiment, the storage racks 4 in the storage system are formed by arranging a plurality of storage racks 4 as shown in fig. 4, that is, the width dimension of the buffer rack is approximately half of the width dimension of the storage racks 4, so the second channel has two types: the second channel below the buffer storage rack can be used for the second transfer robot to pass when the transfer box is not transferred, and the second channel below the storage rack 4 of the part where the buffer storage rack is not arranged can be used for the second transfer robot to pass when the transfer box is transferred or not transferred.

The buffer rack provided in this embodiment is provided with the space 30, where the space may form a first channel through which the lifting mechanism of the second handling robot passes, as shown in fig. 4, where the "passing through" in the "first channel through which the lifting mechanism of the second handling robot passes" described herein may be either passing in the D1 direction or passing in the D1 direction in the reverse direction, or passing in the D2 direction in the reverse direction. When the second transfer robot needs to fetch and discharge the material box relative to the buffer position, the second transfer robot can run below the buffer position to control the lifting mechanism to lift, the lifting mechanism can pass through the first channel along the D2 direction in the lifting process, and the lifting mechanism can pass through the first channel along the reverse direction of the D2 direction in the descending process; when the second transfer robot needs to pass through the storage rack 4 along the width direction of the storage rack 4 with the bin, the jacking mechanism on the second transfer robot passes through the first channel along the direction D1 or the reverse direction of the direction D1.

Taking an example of taking a bin on a buffer position out as needed, combining with fig. 4 and fig. 9 (fig. 9 is a top view), wherein one bin 6 is a bin 60 to be fetched, the second transfer robot can enter below the storage shelf 4 from the second channel along the reverse direction of the D3 direction, turn when reaching the buffer position corresponding to the bin 60 to be fetched, move from the first channel to the position right below the buffer position along the D1 direction, lift the bin 60 to be fetched through a lifting mechanism, then move from the first channel to the outside of the storage shelf 4 along the D1 direction, and finally move from the third channel 44 to the next target working position along the D3 direction.

Taking the case that one bin needs to be carried and placed at one of the buffer positions, as shown in fig. 9, one of the buffer positions is the target buffer position 7, the second carrying robot with the bin can enter the lower part of the storage shelf 4 along the direction of D3 from the second channel, turn around when reaching the column where the target buffer position 7 is located, pass through one storage shelf 4 along the direction of D1 from the first channel and run to the lower part of the target buffer position 7, and then descend through the jacking mechanism to store the bin on the target buffer position 7. The second transfer robot can continue to travel from the first aisle along the direction D1 to the outside of the warehouse rack 4 and finally from the second aisle along the direction D3 to the next target working position.

As can be seen from the above carrying example, by forming the first channel by setting the spacing 30, the detour of the second carrying robot can be reduced, and meanwhile, the occupation of the third channel 44 by the second carrying robot can be reduced, thus, the congestion of the carrying robot can be significantly reduced, and the carrying efficiency can be effectively improved. There are also schemes in the related art in which a channel is provided between a row of buffer bits for a robot to pass through, but in the scheme, the position of the channel is fixed, the effect on reducing the detour of the robot is small, and the scheme is to leave out a channel by eliminating a part of buffer boards, so that the number of buffer bits is also reduced. And in this application, through setting up interval 30 and forming first passageway, this interval 30 does not influence the placing of workbin (can not reduce the quantity of buffering position promptly) to arbitrary first passageway is all can supply the second transfer robot (have or not have the state of workbin all can) to pass through under the condition that the workbin was not placed to the buffering position that corresponds. Even if the storage bin is placed in the cache position, the corresponding first channel can still be used for the second transfer robot without the storage bin to pass through.

The foregoing is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto, and it should be apparent to those skilled in the art that the present application includes but is not limited to the accompanying drawings and what is described in the above specific embodiments. Any modifications which do not depart from the functional and structural principles of the present application are intended to be included within the scope of the claims.
