[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0030] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.
[0031] Please refer to the following: Figure 1 , Figure 2 and Figure 4The distribution robot 60 provided by the embodiment of the present application comprises a body 61, a pulley mechanism 63 installed at the bottom of the body 61, and a lifting mechanism 62 movably installed on the body 61. The body 61 is provided with a containing space 611 which penetrates the body 61 in the longitudinal direction, i.e., the top and bottom of the body 61 are both provided in an open manner. The body 61 can move back and forth along the track frame 10 in the transverse plane, i.e., the plane perpendicular to the longitudinal direction, through the pulley mechanism 63. The lifting mechanism 62 can grab the to-be-transported object and drive the to-be-transported object to move up and down relative to the body 61 in the longitudinal direction. In the embodiment, the to-be-transported object is a turnover box 2 loaded with articles. Since the containing space 611 penetrates the body 61 in the longitudinal direction, when the lifting mechanism 62 grabs the turnover box 2 and drives the turnover box 2 to move up, the grabbed turnover box 2 can pass through the containing space 611 and protrude above the top of the body 61, i.e., the top surface of the grabbed turnover box 2 is higher than the top surface of the body 61, so that the grabbed turnover box 2 is not affected by the height of the body 61. Therefore, the distribution robot 60 can grab and transport more turnover boxes 2 at a time, and the distribution efficiency of the distribution robot 60 is greatly improved.
[0032] The shape of the body 61 and the setting position of the containing space 611 are not limited. In the embodiment, the body 61 is basically square, and the containing space 611 is arranged at the middle of the body 61.
[0033] Please refer to Figure 3 The specific structure of the lifting mechanism 62 is not limited, as long as the lifting mechanism 62 can grab the turnover box 2 and drive the turnover box 2 to move up and down relative to the body 61. For example, the lifting mechanism 62 can comprise a lifting part 621 and a grabbing part 622. The grabbing part 622 is fixed at the bottom of the lifting part 621 and is used to grab the turnover box 2. The lifting part 621 is movably connected with the inner wall of the containing space 611 and can move up and down relative to the body 61. In some embodiments, the grabbing part 622 is provided with a claw which can cooperate with the flange on the periphery of the turnover box 2 to lift the turnover box 2. The lifting part 621 can be a rope. A motor is arranged on the body 61. One end of the rope is connected with the rotating shaft of the motor. When the rotating shaft of the motor rotates, the rope can be wound on the rotating shaft, so that the turnover box 2 grabbed by the claw is driven to move up. When the rotating shaft of the motor reversely rotates, the grabbed turnover box 2 is driven to move down. It can be understood that the lifting part 621 can also be a rack. The lifting part 621 can also be driven to move up and down through the cooperation of the rack and a gear.
[0034] In some embodiments, the lifting mechanism 62 is further provided with a weight sensor, which can detect the weight of the totes 2 grabbed and feed the weight information to the control module. When different sorting robots 60 responsible for the same order feed the weight information of the totes 2 grabbed by them to the control module, the control module can control the different sorting robots 60 to move to the predetermined position in a certain order, for example, the sorting robot 60 grabbing the heavier totes 2 is controlled to move to the predetermined position first and place the totes 2 grabbed by it at the designated position, and then the sorting robot 60 grabbing the lighter totes 2 is controlled to move to the predetermined position and stack the lighter totes 2 grabbed by it on the heavier totes 2, so that the totes 2 are stacked in the designated position in the manner of lighter on top and heavier on bottom, which can avoid the problem of the top totes 2 crushing the bottom totes 2 due to excessive weight, and also can lower the overall center of gravity of the totes 2 stacked together, thereby enhancing the stability of the totes 2 in the transportation process.
[0035] Please refer to Figure 2 and Figure 3 , the pulley mechanism 63 can slide on the track frame 10, which includes a first wheel system 631 and a second wheel system 632, both of which include a plurality of pulleys rotatably mounted on the bottom of the body 61. The pulleys of the first wheel system 631 can move in a first direction, and the pulleys of the second wheel system 632 can move in a second direction, and the first and second movement directions are perpendicular to each other, so that the sorting robot 60 can move in two mutually perpendicular directions, enhancing the flexibility of the sorting robot 60. In actual application, the first wheel system 631 and the second wheel system 632 can be constructed to be capable of lifting relative to the body 61. When the sorting robot 60 needs to move in the first direction, the pulleys of the first wheel system 631 are made to slide with the track frame 10, and the second wheel system 632 is lifted so that it does not contact the track frame 10, so that the pulleys of the second wheel system 632 do not affect the movement of the sorting robot 60 in the first direction; and when the sorting robot 60 needs to move in the second direction, the pulleys of the second wheel system 632 are made to slide with the track frame 10, and the first wheel system 631 is lifted so that it does not contact the track frame 10.
[0036] Please refer to Figure 2 and Figure 5 , the present application also provides a method S100 for using the sorting robot 60, comprising the following steps:
[0037] Step S10, the sorting robot 60 moves above the totes 2 to be transported by the pulley mechanism 63;
[0038] Step S20, the lifting mechanism 62 extends downward and grabs at least one tote 2 to be transported;
[0039] Step S30, the lifting mechanism 62 drives the to-be-transported objects to be grabbed to rise, so as to transport the to-be-transported objects to be grabbed into the accommodation space 611 or make the to-be-transported objects to be grabbed protrude above the top surface of the body 61 through the accommodation space 611;
[0040] Step S40, the sorting robot 60 loaded with the to-be-transported objects moves to a predetermined position;
[0041] Step S50, the lifting mechanism 62 extends downward while driving the to-be-transported objects to be grabbed to move downward, so as to transport the to-be-transported objects to be grabbed to a designated position.
[0042] In some embodiments, step S40 comprises:
[0043] The sorting robot 60 weighs the to-be-transported objects to be grabbed and feeds back the weight information to the control module, and the sorting robot 60 moves to the predetermined position according to the sequence indicated by the control module so that the to-be-transported objects to be grabbed are stacked in the designated position in the manner of light on top and heavy on the bottom. Specifically, when different sorting robots 60 responsible for the same order feed back the weight information of the totes 2 grabbed by them to the control module, the control module will control the sorting robot 60 that grabs the heavier totes 2 to move to the predetermined position first, and then place the totes 2 grabbed by it at the designated position, and then control the sorting robot 60 that grabs the lighter totes 2 to move to the predetermined position, and stack the lighter totes 2 grabbed by it on the heavier totes 2.
[0044] In summary, the sorting robot 60 provided by the application can make the totes 2 to be grabbed protrude above the top surface of the body 61 through the accommodation space 611, so that the height of the totes 2 to be grabbed is no longer affected by the height of the body 61, and the sorting robot 60 can grab and transport a larger number of totes 2 at a time, thereby improving the sorting efficiency of the sorting robot 60.
[0045] The above embodiments are only preferred embodiments of the application, and cannot be used to limit the scope of protection of the application, and any non-essential changes and replacements made by those skilled in the art on the basis of the application all belong to the scope of protection claimed by the application.
