Logistics robots (also known as transfer robots) are important devices in warehouse systems that are capable of transferring target items (e.g., containers) from one location to another in the warehouse system for processing; in addition, the logistics robot can automatically place the target object on the target carrier (such as a goods shelf) to finish the feeding process (such as a box returning process); the target item can also be removed from the target carrier and transported to another designated location.
In some examples, to improve the efficiency of the logistics robot in conveying the target objects, a gantry is generally arranged on a chassis of the logistics robot, a plurality of temporary storage trays are arranged along the height direction of the gantry, and the box taking device of the logistics robot takes the target objects off the target carrier and places the target objects on the temporary storage trays; in this way, the logistics robot can transport a plurality of target objects at a time, so that the conveying efficiency of the target objects can be improved.
However, by arranging the portal on the chassis and arranging the temporary storage tray on the portal along the height direction, the overall height of the logistics robot is higher, that is, the overall gravity center of the logistics robot is higher; in order to ensure the stability of the logistics robot for carrying the target object, the moving speed of the logistics robot is generally reduced, and the conveying efficiency of the logistics robot on the target object is affected.
In some examples, there is also a way to reduce the overall height of the logistics robot, thereby increasing the running speed of the logistics robot and increasing the transport efficiency of the target object.
However, after the height of the logistics robot is reduced, the number of target objects to be transported at a time is limited, so that the transportation efficiency of the logistics robot is reduced.
Therefore, the embodiment of the application provides a box taking device and a logistics robot, which can improve the number of target objects carried by the logistics robot at a time and the carrying efficiency of the logistics robot.
Fig. 1 is a schematic diagram of the overall structure of a box taking device according to an embodiment of the present application.
Referring to fig. 1, an embodiment of the present application provides a box taking device 10, including: a carrier 110 and a pick-up assembly 120; wherein the carrier 110 may be a base of the box-taking device 10, in some examples, the carrier 110 may be used to carry a target item. In some examples, the carrier 110 may also be a scratch pad tray or a scratch pad plate.
In embodiments of the present application, the carrier 110 may be in a plate or disc type structure, and in some examples, the carrier 110 may also be in a box or frame type structure. In some alternative examples, the carrier 110 may be made of a hard nonmetallic material (e.g., a hard plastic or an engineering plastic); in other alternative examples, the carrier 110 may be made of an alloy material such as aluminum alloy or stainless steel.
Referring to fig. 1, in the embodiment of the present application, a plurality of carrying positions 111 are provided on a carrying member 110, and the carrying positions 111 are used for placing a target object. In some examples, each load station 111 may house at least one target item. In a specific setting, the load bearing bits 111 may be set according to standard dimensions of the target article. In the embodiment of the application, the target object may be a container (such as a packing box, an in-line box or an oblique box, etc.).
With continued reference to fig. 1, in an embodiment of the present application, the picking assembly 120 is disposed on the carrier 110, and the picking assembly 120 can be selectively extended to retract the carrier 110, thereby transferring the target object between the target cargo space and the carrying location 111.
It will be appreciated herein that the retrieval assembly 120 may extend or retract the carrier 110 under the drive of the telescoping members. The picking assembly 120 generally has two working processes, namely a picking process and a returning process, which are respectively described in the embodiment of the present application.
The material taking process comprises the following steps:
the fetching assembly 120 may extend from the carrier 110 under the driving of a telescopic member, where the telescopic member may be a telescopic fork, a cylinder, a telescopic rod, a scissor fork, or the like; after the fetching assembly 120 moves towards the target cargo space and contacts with the target cargo space, the fetching assembly 120 can apply a force towards the carrier 110 to the target cargo space, so as to drive the target object to move towards the carrier 110, and after the fetching assembly 120 returns to the carrier 110, the target object is moved onto the carrier 110, so that the fetching process of the target object is completed.
In some examples, the retrieval assembly 120 may be a fork-holding structure; in other examples, the article taking assembly 120 may also be a sucking disc 122 structure, a magnetic attraction structure or a claw structure, etc., and the article taking assembly 120 is shown as a sucking disc 122 structure in the drawings of the present application as a specific example. It can be appreciated that the mode of action of the fork holding structure, the suction cup 122 structure, the magnetic suction structure and the claw structure on the target object can be referred to the detailed description in the related art, and the embodiments of the present application will not be repeated.
And (3) the following process:
The fetching assembly 120 can push out the target object on the carrying position 111 under the driving of the telescopic piece, namely, push the target object from the carrying position 111 to the target goods space; after the target object moves to the designated position on the target cargo space, the object taking assembly 120 releases the interaction with the target object and returns to the bearing member 110 under the driving of the telescopic member, thereby completing the object returning process of the target object.
It can be understood that in order to reduce the overall weight of the logistics robot, the transportation speed of the logistics robot is increased; in the embodiment of the present application, only one of the picking assemblies 120 may be provided, that is, one of the picking assemblies 120 corresponds to the plurality of carrying positions 111. In particular arrangements, the retrieval assembly 120 may be configured to move or switch positions between the plurality of load positions 111, such as from one load position 111 to another load position 111, to effect a position switch between the plurality of load positions 111 to effect a transfer of items between the plurality of load positions 111 and the target cargo space.
As an alternative example, the fetching assembly 120 may be rotatably disposed between two adjacent carrying positions 111, and in use, the fetching assembly 120 may rotate to one carrying position 111 after the fetching or returning of the object is completed at one carrying position 111, and perform the fetching and returning operation of the object to the other carrying position 111.
Alternatively, the picking assembly 120 may be detachably connected to the carrier 110, for example, each carrying location 111 may be provided with a corresponding mounting location of the picking assembly 120; after the fetching assembly 120 completes the fetching operation of the target object from one of the carrying positions 111, the fetching assembly 120 may be mounted on the other carrying position 111, and the fetching operation of the target object from the other carrying position 111 may be performed.
According to the box taking device 10 provided by the embodiment of the application, the plurality of bearing positions 111 are arranged on the bearing piece 110, and the object taking assembly 120 arranged on the bearing piece 110 is arranged to be capable of switching positions or moving among the plurality of bearing positions 111; in this way, the fetching component 120 can switch to the other carrying locations 111 after completing the transfer of the target object between the target cargo location and one of the carrying locations 111, and complete the transfer of the target object between the other carrying locations 111 and the target cargo location; that is, the box taking device 10 can place a plurality of target objects at a time, so that the logistics robot can transfer and transport a plurality of target objects at a time, the number of target objects carried by the logistics robot at a time is increased, and the carrying efficiency of the logistics robot is improved.
Fig. 2 is a schematic diagram of another overall structure of the box taking device 10 according to the embodiment of the present application, fig. 3 is a schematic diagram of another overall structure of the box taking device 10 according to the embodiment of the present application, and fig. 4 is a schematic diagram of a structure in which the object taking assembly 120, the first driving structure 130 and the carrier 110 of the box taking device 10 according to the embodiment of the present application are matched.
Referring to fig. 2-4, in some alternative examples of embodiments of the application, the case retrieval device 10 further includes a first drive structure 130, the first drive structure 130 being coupled to the retrieval assembly 120. In the embodiment of the present application, the first driving structure 130 can drive the fetching assembly 120 to switch positions or move between the plurality of carrying positions 111.
In some examples, and with reference to the detailed description of the foregoing embodiments of the application, the retrieval assembly 120 may be rotatably mounted between two adjacent carrying locations 111, i.e., the retrieval assembly 120 may be rotated from one carrying location 111 to another carrying location 111 and the retrieval of the target item may be performed at the other carrying location 111. Thus, in the embodiment of the present application, the first driving structure 130 may be a combination of components such as a motor and a gear. For example, a drive motor may be mounted on the carrier 110, with an output shaft of the drive motor mounting a drive gear; in addition, a driven gear is mounted on a rotation shaft of the picking assembly 120, which rotates relative to the carrier 110, and the driving gear is in driving connection with the driven gear.
Here, it is understood that the driving gear and the driven gear may be in driving connection, in which the driving gear is meshed with the driven gear, or in driving connection, in which the driving gear and the driven gear are in belt driving manner, such as a chain, a belt or a timing belt; that is, the driving motor can drive the fetching assembly 120 to rotate, and only need to rotate from one bearing position 111 to the other bearing position 111.
In some examples, an output shaft of the driving motor may be connected to a rotation shaft of the fetching assembly 120 through a speed reducer or a gearbox, so as to drive the fetching assembly 120 to rotate.
In the embodiment of the present application, by providing the first driving structure 130, the first driving structure 130 is connected to the fetching assembly 120, and drives the fetching assembly 120 to switch positions or move among the plurality of carrying positions 111. In this way, the automation degree of the switching position or movement of the fetching assembly 120 among the plurality of bearing positions 111 is improved, so that the fetching efficiency of the logistics robot, that is, the transportation efficiency of the fetching robot for carrying the target object can be improved.
In some examples, referring to fig. 2-4, the first driving structure 130 includes: a first transmission member 131 and a first driving member 132. The first transmission member 131 extends along the arrangement direction of the plurality of bearing positions 111, and the object taking assembly 120 is disposed on the first transmission member 131.
Referring to fig. 1 and 4, in an embodiment of the present application, the arrangement direction of the plurality of bearing bits 111 may be arranged along the direction shown by the y-axis in the figure. Generally, the fetching assembly 120 extends out of the carrier 110 and retrieves the target object from the target cargo space onto the carrier 110, and the fetching assembly 120 has a telescopic direction (which may also be referred to as a fetching direction) on the carrier 110; in the embodiment of the present application, referring to fig. 1 and fig. 4, the object taking direction may be a direction shown by an x-axis in the drawing, and in order to avoid interference between target objects on different carrying positions 111, in the embodiment of the present application, the arrangement direction of the plurality of carrying positions 111 may intersect with the object taking direction, for example, the arrangement direction of the plurality of carrying positions 111 is perpendicular or approximately perpendicular to the object taking direction. In the embodiment of the present application, the first transmission member 131 is configured to extend along the arrangement direction of the plurality of bearing positions 111, so that when the first transmission member 131 moves, the first transmission member 131 can drive the object taking assembly 120 disposed on the first transmission member 131 to switch positions or move between the plurality of bearing positions 111.
In some examples, the first driving member 132 is connected to the first transmission member 131, and the first driving member 132 is configured to drive the first transmission member 131 to move, so as to switch the position or move the fetching assembly 120 between the plurality of carrying positions 111.
It can be appreciated that in the embodiment of the present application, the first driving member 132 may be a linear driving member such as a telescopic cylinder, a piston cylinder or a linear motor; for example, the telescopic cylinder may be disposed on the carrier 110, and the free end of the telescopic cylinder is connected with the first transmission member 131, at this time, the first transmission member 131 may be a slider slidably disposed on the carrier 110, and when the free end of the telescopic cylinder stretches, the slider is driven to move along the arrangement direction of the plurality of carrying positions 111, so as to drive the fetching assembly 120 to move.
In some examples, when the first driving member 132 is a linear driving member such as a telescopic cylinder, a piston cylinder or a linear motor, the output shaft of the first driving member 132 may be directly connected to the fetching assembly 120, that is, the first driving member 132 directly outputs power to the fetching assembly 120, and in this case, the output shaft of the first driving member 132 may be understood as the first transmission member 131.
In other examples of the embodiment of the present application, referring to fig. 4, the first transmission member 131 may also be a screw extending along the arrangement direction of the plurality of bearing positions 111. That is, the circumference of the lead screw may be parallel or approximately parallel to the direction shown by the y-axis in FIG. 4; correspondingly, a perforation can be arranged on the object taking component 120, an internal thread can be arranged in the perforation, and a lead screw is connected with the object taking component 120 through the thread; thus, when the first driving member 132 drives the screw to rotate, the pickup assembly 120 can move along the axial direction of the screw, thereby switching positions or moving among the plurality of bearing positions 111, since the screw is connected with the pickup assembly 120 through threads.
In some examples, a screw nut may be disposed on the fetching assembly 120, and the screw nut is matched with the screw thread, so as to drive the fetching assembly 120 to move.
For example, when the first transmission member 131 is a screw, the first driving member 132 may be a motor that can be rotated forward and backward, for example, in some examples, the first driving member 132 may be a synchronous motor, a stepping motor, a servo motor, or the like.
In some alternative examples, the first transmission member 131 may also be a transmission belt, where the transmission belt may be a chain, a belt, a timing belt, or the like; of course, in some examples, the belt may also be steel wire.

In the embodiment of the present application, the first driving member 131 is disposed along the arrangement direction of the plurality of bearing positions 111, the fetching assembly 120 is disposed on the first driving member 131, and the first driving member 132 drives the fetching assembly 120 to switch positions or move between the plurality of bearing positions 111 through the first driving member 131, so that the first driving member 132 can conveniently control the positions of the fetching assembly 120, and can accurately control the fetching assembly 120 to reach each bearing position 111, thereby facilitating the fetching operation of the target object at each bearing position 111.
In other examples of embodiments of the application, the first drive 132 has a motor encoder (not shown); the motor encoder is configured to determine the distance that the retrieval assembly 120 moves between the plurality of load positions 111 to determine the retrieval location of the retrieval assembly 120 on each load position 111.
For example, referring to fig. 4, when the first driving member 132 is powered on, the first driving member 132 may drive the pickup assembly 120 to move in the negative y-axis direction and move to the initial position (a position where the pickup assembly cannot move continuously), at this time, the motor encoder may be in a zero position, when the pickup or the return is required, position information may be sent to the motor encoder, for example, the motor encoder may send position information to the motor encoder, the motor encoder determines a distance between the target position and the initial position according to the position information, then the first driving member 132 drives the pickup assembly 120 through the first transmission member 131, so that the pickup assembly 120 moves in the positive y-axis direction in fig. 4, at this time, the motor encoder determines a moving distance of the pickup assembly 120 according to a rotation angle of the motor, and when the pickup assembly 120 moves to the target position (the moving distance of the pickup assembly 120 determined by the motor encoder is the same as or equal to a distance between the initial position and the target position), the first driving member 132 stops working, so as to accurately position the pickup assembly 120 when the pickup assembly 120 moves between the plurality of carrying positions 111. In this way, it is ensured that the picking assembly 120 can be accurately aligned with the target item, and the transfer efficiency of the target item is improved.

That is, in the embodiment of the present application, both ends of the first driving structure 130 are slidably connected to the second sliding rail 160. In this way, by arranging two second sliding rails 160, the two second sliding rails 160 are relatively arranged at two ends of the first driving structure 130, so that the stability of the first driving structure 130 and the fetching assembly 120 moving along the fetching direction can be improved.
In further alternative examples of embodiments of the present application, referring to FIG. 5, the box handling apparatus 10 further includes a mounting block 170; the mounting seat 170 is slidably disposed on the second sliding rail 160; the first driving structure 130 is disposed on the mounting base 170.

In some alternative examples of embodiments of the present application, with continued reference to FIG. 5, a relief 171 is provided on the mount 170, the relief 171 being configured to relieve the second drive member 152.
In some examples, referring to fig. 5, the relief 171 may be a notch formed in a side of the mount 170 facing the second driving member 152. It is understood that the relief portion 171 may extend in the arrangement direction of the plurality of bearing locations 111. In some alternative examples, the avoidance portion 171 may be a notch formed in the mounting seat 170.
In some examples, referring to fig. 5, when the second driving member 152 drives the mounting base 170 through the second transmission member 151 to move along the negative x direction in fig. 5, that is, the fetching assembly 120 returns to the carrying position, because the second driving member 152 remains stationary, when the mounting base 170 moves to the rear end of the carrying position 111, the second driving member 152 may be embedded in the avoiding portion 171, so that the mounting base 170 and the fetching assembly 120 disposed on the mounting base 170 may move backward as much as possible, and the target object may enter into the carrying position 111 as much as possible, thereby improving the safety of conveying the target object.
In the embodiment of the present application, the avoiding portion 171 is disposed on the mounting seat 170, so that when the second driving member 152 drives the object taking assembly 120 to retract into the bearing position 111, the second driving member 152 can enter into the passing avoiding portion 171, thereby reducing the occupied space of the second driving member 152 and the mounting seat 170 along the object taking direction (for example, the direction shown by the x axis in fig. 5), so that the target object can completely enter into the bearing position 111, and improving the effectiveness of the bearing position 111 for supporting the target object.

For example, in some examples, the second transmission member 151 may be connected to the picking assembly 120, where the second driving member 152 is disposed on the first driving structure 130, for example, the second driving member 152, the second transmission member 151, and the picking assembly 120 are disposed on the mounting base 170, and the first driving structure 130 drives the mounting base 170 to move along the arrangement direction of the plurality of bearing positions 111; the second driving member 152 drives the second driving member 151 to drive the fetching assembly 120 to move along the fetching direction.
In further alternative examples of embodiments of the present application, and as shown with reference to FIG. 1, the carrier 110 has a bottom wall 112 and a top wall 113, wherein a receiving space is defined between the bottom wall 112 and the top wall 113 for receiving a target item, and the retrieval assembly 120 is positioned within the receiving space. In some alternative examples, access assembly 120 is provided on top wall 113.
That is, in embodiments of the present application, the carrier 110 may be configured as a box-type structure, or in some examples, the carrier 110 may be configured as a frame-type structure, wherein the picker assembly 120 is disposed on the top wall 113 of the box-type or frame-type structure and extends downward.
It will be appreciated that typically the target item is stored on a target cargo space (e.g. a shelf), that is, the target item has a certain height difference from the ground; in order to increase the moving speed of the logistics robot, a mode of reducing the gravity center of the logistics robot is adopted, that is, the overall height of the logistics robot is smaller; when the object is to be picked up, after the logistics robot moves to the object cargo space, the height of the box picking device 10 needs to be lifted by a lifting mechanism (which may also be referred to as a lifting mechanism 30 in some examples); in the embodiment of the application, the object taking assembly 120 is arranged on the top wall 113 of the bearing member 110, so that the object taking assembly 120 has a certain height existing at the top of the bearing member 110, and therefore, the height of the lifting mechanism for the whole object taking assembly 120 to be lifted can be reduced, namely, the work of the lifting mechanism for the box taking device 10 in the height direction can be reduced, and the energy consumption can be effectively saved.
In some examples, the first drive structure 130 and the second drive structure 150 that drive the retrieval assembly 120 may also be disposed on the top wall 113 of the carrier 110. In this way, the bottom wall 112 of the carrier 110 is ensured to be flat, so that the object picking assembly 120 can conveniently move the target object.
In further alternative examples of embodiments of the present application, with continued reference to FIG. 1, a divider 114 is provided on the bottom wall 112, the divider 114 being configured to divide the bottom wall 112 into a plurality of load-bearing locations 111 arranged side-by-side.

It is also understood that the direction of extension of the divider 114 may extend in a direction that is generally parallel to the direction of extension of the retrieval assembly 120 (which may also be understood as the retrieval direction or the direction shown by the x-axis in fig. 1).
In the embodiment of the present application, the partition member 114 is disposed on the bottom wall 112, so that the bottom wall 112 is divided into a plurality of bearing positions 111 arranged side by the partition member 114; in this way, after the object taking assembly 120 transfers the object to one of the bearing positions 111, the partition 114 can limit the object to the corresponding bearing position 111, so that the object taking assembly 120 can conveniently take the object to the other bearing positions 111, and interference caused by the object on one bearing position 111 entering the other bearing positions 111 to the movement of the object taking assembly 120 or interference caused by the object on the other bearing positions 111 moving can be avoided; facilitating retrieval of the target item by the retrieval assembly 120.
In some alternative examples, the front end of the divider 114 has a lead-in chamfer 1141, the lead-in chamfer 1141 forming a necked-in configuration with the side wall of the carrier 110. In an embodiment of the present application, the front end of the partition 114 may be the end of the box-taking device 10 facing the target cargo space, where the partition 114 faces the target cargo space.
In the embodiment of the present application, the guide slope 1141 is provided at the front end of the partition 114; in this way, when the fetching assembly 120 transfers the target object from the target cargo space to the carrying position 111, the guiding inclined plane 1141 can correct a partial deflection of the target object, which is beneficial to the target object to smoothly enter the corresponding carrying position 111, so as to facilitate the transfer efficiency of the target object.
Illustratively, in the embodiment of the present application, the distance by which the partition 114 protrudes from the bottom wall 112 is less than or equal to the distance between the picker assembly 120 and the bottom wall 112. That is, there is a gap between the top of the divider 114 and the top wall 113 of the carrier 110; in this way, the picker assembly 120 is facilitated to be moved from one load location 111 to another load location 111.
It will be appreciated that in some examples, an avoidance gap may be provided on the partition 114, and two adjacent bearing positions 111 may be communicated through the avoidance gap; in this way, the retrieval assembly 120 may be moved from the evasion gap between adjacent ones of the load positions 111, thereby switching the position of the retrieval assembly 120 between the two load positions 111.
In other alternative examples of embodiments of the present application, as shown with reference to fig. 1 and 2, the pick up assembly 120 includes a mounting plate 121 and a suction cup 122, the mounting plate 121 is disposed on the carrier 110, the suction cup 122 is disposed on the mounting plate 121, and the suction cup 122 is configured to attract a target item.
In some examples, a vacuum pump may be provided on the logistics robot, a vacuum channel may be provided on the mounting plate 121, and the vacuum pump is in communication with the inner cavity of the suction cup 122 through the vacuum channel; when the vacuum pump vacuumizes the inner cavity of the sucker 122, the sucker 122 is adsorbed on the target object, so that the target object is driven to move.
It will be appreciated that in the embodiment of the present application, the mounting plate 121 may be disposed on the carrier 110 through the first driving structure 130, that is, the mounting plate 121 may be indirectly connected to the carrier 110.
