The pickup device 203 may be mounted on the fixed bracket 204 and used to place goods on the pallet 205 or to pick up goods on the pallet 205.

It is understood that the transfer robot 200 capable of cooperating with the cargo handling apparatus 100 of the present application includes, but is not limited to, the structure shown in fig. 2, and may also be another structure, but it is required to ensure that each pallet 205 and each storage unit 2 of the cargo handling apparatus 100 are arranged in one-to-one correspondence in the transfer robot 200, and the height of the cargo carrying surface of the pallet 205 is substantially the same as the height of the cargo carrying surface of the storage unit 2, so that the cargo can be smoothly moved between the storage unit 2 and the pallet 205.

The loading and unloading process of the cargo-handling device 100 of the present application is described below with reference to fig. 2.

In the unloading process, the transfer robot 200 moves from the position shown in fig. 2 in the direction approaching the cargo handling apparatus 100, and when the transfer robot 200 reaches the unloading position, that is, when the fixed bracket 204 of the transfer robot 200 reaches the vicinity of the cargo inlet of the cargo handling apparatus 100, the pallet 205 of the transfer robot 200 and the storage unit 2 correspond to each other one by one, and at this time, the robot arm 5 and the movable element 51 move and are located at the front side Q in the conveying direction K of the cargo, and the movable element 51 is stopped at the side of the cargo in the conveying direction K. The robot arm 5 then moves the movable member 51 toward the cargo handling device 100 and the rolling conveyor 22 rotates, at which time the cargo starts moving from the pallet 205 toward the storage unit 2 under the combined action of the traction force generated by the dragging of the movable member 51 and the rotation of the rolling conveyor 22 until the cargo completely enters the storage unit 2, and the unloading process is completed. In this case, the loads on the pallets 205 on the respective floors of the respective transfer robots 200 can be simultaneously transferred to the storage units 2.

Furthermore, in order to move the robot arm 5, the drive assembly may further comprise a second drive means for driving the travelling carriage 6 to move relative to the support 1.

The structure of each part of the cargo-handling device 100 will be described in detail below.

Fig. 3 is a schematic structural diagram of the bracket 1 in the cargo handling apparatus 100 according to an embodiment of the present application.

Referring to fig. 3, the stand 1 includes columns 11 and support frames 12, which may be located in spaces between the columns 11 when the number of the columns 11 is plural. The bottom of the support frame 12 and the upright 11 together support the cargo-handling device 100, and the support frame 12 includes a support portion 120 extending along the ground.

In the above scheme, the support frame 12 is arranged, so that the support frame 12 and the upright post 11 support the cargo handling device 100 together, wherein the upright post 11 plays a main supporting role, and the support frame 12 plays an auxiliary supporting role. Compared with the prior art in which the cargo-handling device 100 is supported only by the upright 11, the number of mechanisms for supporting the cargo-handling device 100 is increased, and further, since the first support portion 120 extends along the ground, the contact area between the support portion 120 and the ground can be increased, so that the cargo-handling device 100 is stably supported.

Referring to fig. 3, a front side Q in the cargo conveying direction K is indicated by an arrow, and a direction opposite to the front side is a rear side H. For example, the pillar 11 in the present application may include a front pillar 121 located on the front side of the rack 1 in the cargo conveying direction and a rear pillar 122 located on the rear side of the rack 1 in the cargo conveying direction. The number of the upright columns 11 can be set according to needs, for example, the application takes two front upright columns 121 and two rear upright columns 122 as an example to explain, and the description is omitted here for the case that the number is other.

The support frame 12 further comprises a center pillar 123; the center pillar 123 is used for supporting the middle portion of the bracket 1, is located between the front pillar 121 and the rear pillar 122, and is used for supporting the portion of the bracket 1 located between the front pillar 121 and the rear pillar 122. In the embodiment of the present invention, when the cargo-handling device 100 and the transfer robot 200 are used in cooperation, the support 1 may further be provided with an avoidance groove 13 for avoiding the moving chassis 202 of the transfer robot 200.

Specifically, referring to fig. 3, the number of the avoidance grooves 13 may be two, and the avoidance grooves 13 are respectively located on one side of the goods outlet 32 and the goods inlet 31 (the goods inlet is an opening on the side of the storage unit away from the goods outlet), and the avoidance groove 13 on the side of the goods inlet 31 is described as an example, when the support 1 includes a plurality of uprights 11, for example, two front uprights 121 and two center uprights 123, and two rear uprights 122, the two front uprights 121 and the two center uprights 123 are spaced apart, and the two center uprights 123 and the two rear uprights 122 are spaced apart, so as to form the avoidance groove 13 for avoiding the moving chassis 202 of the transfer robot 200, it can be understood that the opening of the avoidance groove 13 may face the transfer robot 200, that is, the opening direction of the goods outlet 32 or the goods inlet 31 is the same. It should be understood that the evacuation groove 13 herein refers to an evacuation space, and may be an open space formed by a gap between the pillars as described above, or may be a relatively closed space formed by a continuous evacuation chamber, as long as the evacuation groove can be accessed by the moving chassis 202 of the transfer robot 200, which is not limited in the present application.

In the embodiment of the present application, when the transfer robot 200 and the cargo-handling device 100 are opposed to each other, there is a possibility that the transfer robot 200 does not reach a predetermined loading or unloading position, and the cargo-handling device 100 performs a loading and unloading operation, and in this case, a loading and unloading failure is likely to occur, and the loading and unloading reliability is low. In order to avoid this, the control assembly may further include a sensing unit electrically connected to the controller, the sensing unit being disposed on the support frame 1 for emitting a sensing signal when the transfer robot moves to a loading position or a unloading position opposite to the cargo-handling device 100, so that the controller controls the driving assembly to perform the loading or unloading operation according to the sensing signal.

Fig. 4 is a partially enlarged view of a portion a of fig. 3, and fig. 5 is a partially schematic structural view of a bracket of a cargo handling device according to an embodiment of the present invention. Referring to fig. 3 and 4, in the embodiment of the present application, as described above, the bottom of the bracket 1 has the avoidance groove 13. The sensing unit may include a first sensing unit 33, the first sensing unit 33 is disposed in the avoidance groove 13, and the first sensing unit 33 is configured to emit a sensing signal when the moving chassis 202 of the transfer robot 200 is received in the avoidance groove 13. In the embodiment of the present application, the number of the first sensing units 33 is at least one. For example, as shown in fig. 3, the first sensing unit 33 may be located at a position opposite to the moving chassis 202 of the transfer robot 200.

In other examples, in order to make the determination of the sensing units more accurate, the number of the first sensing units 33 is at least two, and different first sensing units 33 are disposed at different positions relative to the avoidance slot 13; the controller is used for controlling the walking frame 6 to carry out loading and unloading operations when at least one first sensing unit 33, for example, all the first sensing units 33 send out sensing signals. This prevents the occurrence of a situation in which the transfer robot 200 cannot be accurately measured due to, for example, a failure in part of the first sensing units 33.

Referring to fig. 3 and 4, for example, the first sensing unit 33 may include an activation switch 331, the activation switch 331 is located in the avoidance slot 13 and may be electrically connected to the controller, and the activation switch 331 is configured to touch the transfer robot 200 when the transfer robot 200 moves into the avoidance slot 13 to send a sensing signal to the controller.

In this embodiment, the start switch 331 includes a switch bracket 332 and a detection rocker arm 333, a first end of the detection rocker arm 333 is rotatably connected to the switch bracket 332, a second end of the detection rocker arm 333 is located in the avoiding groove 13 for touching the transfer robot 200, and the switch bracket 332 may send out a sensing signal when the detection rocker arm 333 rotates. As shown in fig. 4, the on and off positions of the start switch 331 are shown. In the embodiment of the present application, the first sensing unit 33 may include a proximity sensor, and a sensing region of the proximity sensor is located in the avoidance groove 13. Illustratively, the proximity sensor is an infrared proximity sensor or a lidar.

In the following description, the case where the start switch 331 is provided is described, in which the moving chassis 202 of the transfer robot 200 enters the escape groove 13, but when the transfer robot 200 has not reached the predetermined loading/unloading position, the moving chassis 202 does not contact the start switch 331, the start switch 331 is in an off state, and the transfer robot 200 does not perform the loading/unloading operation. When the transfer robot 200 reaches the predetermined loading/unloading position, the movable chassis 202 contacts the start switch 331, and triggers the start switch 331 to operate, the start switch 331 is turned on, and the transfer robot 200 performs the loading/unloading operation.

With continued reference to fig. 3, a top frame 124 is also attached to the top of the columns 11, the top frame 124 being attached between the four columns 11. For a better support of the storage unit 2, the support 1 further comprises an end connection 14, the end connection 14 being connected between two uprights 11 arranged in the goods output direction K, and two opposite ends of the storage unit 2 can be connected between two oppositely arranged end connections 14.

Further, a guide member 141 may be further connected to the end connector 14, the guide member 141 being located inside the end connector 14, and the guide member 141 extending along the conveying direction K of the goods and guiding the goods when the goods are delivered out of the storage unit 2 or the goods enter the storage unit 2. In the case where storage unit 2 is fixed to end connector 14, guide 141 is located at a position above the bottom of storage unit 2.

In the present embodiment, 4 columns, that is, two front columns 121 and two rear columns 122 are arranged in parallel, and the 4 columns are located at approximately four vertices of a rectangle in a plan view. The storage unit 2 may be located between 4 columns and disposed on the 4 columns.

When the storage unit 2 has a plurality of storage units, the storage units 2 are arranged in a vertical direction, for example, at intervals in the height direction of the column 11, so that the goods can be stored at different positions in the height direction. It is understood that since the storage units 2 of each layer are arranged at intervals in the height direction and stacked, the storage units 2 of each layer can be loaded with the goods, and a loading space 23 for loading the goods is formed between each storage unit 2 of each layer and the storage unit 2 of the next adjacent layer.

It should be noted that the set height of each layer of the storage units 2 corresponds to the set height of the pallet 205 on the transfer robot 200 one to one, so that the goods on the storage units 2 can smoothly enter the pallet 205. In addition, the arrangement of the storage units 2 in the present application is not limited to this, and a plurality of storage units 2 may be provided in the width direction of the rack 1. In the embodiment of the present application, the length of the storage unit 2 in the conveying direction K of the goods is greater than or equal to the length of the goods in the direction. So that the goods can be completely accommodated in the storage unit 2.

In the embodiment of the present application, the number of the rolling conveyors 22 in each storage unit 2 is plural, the plural rolling conveyors 22 are arranged side by side along the conveying direction of the goods, and the rotation axes of the plural rolling conveyors 22 are parallel to each other. In addition, the rolling conveyor 22 has an outer contoured surface in rolling contact with the goods for moving the goods into and out of the storage unit 2. Illustratively, the rolling conveyor 22 is a rotating roller or a conveyor belt. When the rolling transfer member 22 is a rotating roller, both ends of the rotating roller are rotatably supported by the end-portion connecting member 14, and the roller surface of the rotating roller is rotatable and forms the outer contour surface capable of rolling. And when the number of the rotating rollers is plural, the rotating shafts of the plural rotating rollers are arranged in parallel with each other.

Further, the rolling conveyors 22 may include a driving rolling conveyor and a driven rolling conveyor, the driving rolling conveyor is connected to the first driving device and driven by the first driving device to rotate around its rotation axis, and the driven rolling conveyor and the driving rolling conveyor are linked to each other and driven by the driving rolling conveyor to rotate. For example, the rolling transfer 22 may be a plurality of cooperating v-ribbed rollers rotatably connected between the two opposing end connections 14. And the adjacent V-ribbed belt rollers realize linkage through V-ribbed belts, so that the V-ribbed belt rollers serving as the active rolling conveying pieces can drive the other V-ribbed belt rollers to rotate together.

In this embodiment, the cargo handling apparatus 100 may further include a lifting mechanism, each storage unit 2 may be connected to the support 1 through the lifting mechanism, and the lifting mechanism is configured to drive the storage unit 2 to ascend or descend, so that the cargo outlets 32 are located at different heights. The lifting mechanism may be, for example, a lifting mechanism driven by an air cylinder.

In some embodiments, referring to fig. 11 described later, the cargo handler 100 further includes a lifting mechanism 93, the lifting mechanism 93 having a carrying platform 931 abutting the cargo outlet 32 of the storage unit 2 and/or the outlet 31 on a side opposite to the cargo outlet 32, and a lifting module 932 for adjusting the height of the carrying platform 931 to convey the cargo to and/or from between the storage unit 2 and the external conveyor line equipment. Thus, when there is a gap between the goods outlet 32 or the goods inlet and the external transportation line equipment, the bearing platform 931 can play a role of auxiliary bearing, preventing the goods from being stuck in the gap.

With continued reference to fig. 3, the cargo handling apparatus 100 further includes a loading/unloading position detecting sensor 90, the loading/unloading position detecting sensor 90 is disposed on the bracket 1, and the loading/unloading position detecting sensor 90 is located at the cargo inlet 31 and/or the cargo outlet 32, and is configured to detect whether the cargo extends to the outside of the storage unit 2. For example, the loading/unloading position detection sensors 90 may be respectively located in the uppermost storage unit and the lowermost storage unit in the vertical direction. Optionally, the loading and unloading position detection sensor may be a reflective photoelectric sensor. Illustratively, when the loading/unloading position detecting sensor 90 detects the passing of the goods, which is described as being in the normal loading/unloading operation, the rolling conveyor 22 can normally rotate to move the goods into and out of the storage unit 2.

In an embodiment of the application, the control assembly comprises, in addition to the controller, a sensor unit, where the sensor unit is adapted to detect the position of the load and/or the speed of movement of the load. The first driving device and the sensor unit are electrically connected with the controller, and the controller is used for controlling the rotating state of the rolling conveying piece 22 according to the motion state of the goods so as to match with the goods carrying mechanism to convey the goods from the outer side of the storage unit 2 into the storage unit 2 and then to the outer side of the goods outlet 32. It should be noted that the motion state of the cargo includes at least one of the following: the position of the goods, the moving speed of the goods and the moving direction of the goods.

In the embodiment of the present application, the sensor unit includes at least one of the speed sensor 8 and the position sensor. For example, the sensor unit includes a speed sensor 8 electrically connected to the controller, and the speed sensor 8 is provided in the storage unit 2. Referring to fig. 5, the speed sensors 8 are two in number and are respectively provided at a position of the end connection 14 close to the cargo outlet 32 and at a position of the end connection 14 away from the cargo outlet 32. In addition, as for the kind of the speed sensor 8, a sensor commonly used in the art may be employed, and the speed sensor 8 is exemplified by a photoelectric sensor.

In the cargo-handling device 100 of the present application, there are two types of cargo access for one of the storage units 2. Goods enter the storage unit 2 through the goods outlet 32, and are conveyed out of the storage unit 2 through the goods outlet 32; alternatively, the goods enter the storage unit 2 from the side of the storage unit 2 opposite to the goods outlet 32, and are output to the outside of the storage unit 2 through the goods outlet 32. Therefore, the detection of the cargo speed is also described in the case where the cargo inlet 31 and the cargo outlet 32 of the storage unit 2 are oppositely disposed.

As one embodiment, referring to fig. 10 described later, the goods enter the storage unit 2 from the goods exit 32, and the two sets of speed sensor 8 units include a first speed sensor 81 and a second speed sensor 82, the first speed sensor 81 being located between the second speed sensor 82 and the goods exit 32; at this time, the moving speed of the goods detected by the first speed sensor 81 is greater than, less than or equal to the moving speed of the goods detected by the second speed sensor 82, and the controller is configured to control the rotation state of the rolling conveyor 22 according to the speed of the goods. It will be appreciated, among other things, that the second speed sensor 82 is located on the opposite side of the storage unit 2 from the cargo outlet 32. The arrangement is that the speed of the goods near the goods outlet 32 is higher than that of the goods far from the goods outlet 32, or the goods are kept at a stable speed, so that when the goods are unloaded, the speed of the goods at the goods outlet 32 is higher than that of the goods far from the goods outlet 32, or the goods are kept at a stable speed value or interval, or the moving speed is increased when the speed of the goods is slow, and the goods can smoothly enter the storage unit 2 from the freight robot 200; during loading, the speed of the cargo away from the cargo outlet 32 is lower than that of the cargo outlet 32, and the cargo speed is faster and faster during loading, or the cargo speed is kept at a stable speed value or interval, or the moving speed is increased when the cargo speed is lower, so that the cargo can smoothly enter the transfer robot 200 from the storage unit 2. Here, the rotation state of the rolling conveyor 22 includes at least one of: the rotational speed of the rolling conveyor 22, the rotational direction of the rolling conveyor 22, and the start-stop status of the rolling conveyor 22.

As another embodiment, referring to fig. 11 described later, the goods enter the storage unit 2 through the goods inlet 31, and the sensor unit may include a third speed sensor 83 and a fourth speed sensor 84, and the third speed sensor 83 and the fourth speed sensor 84 are sequentially disposed between the goods inlet 31 and the goods outlet 32 at intervals.

With continued reference to fig. 5, in the present embodiment, the cargo-handling device 100 further includes a first position sensor 91, and the first position sensor 91 is disposed on the storage unit 2 and is configured to detect the position of the cargo in the storage unit 2. Specifically, the first position sensor 91 is located at a position close to the rear side H of the end connector 14 in each storage unit 2, and both the second driving device and the first position sensor 91, which will be described later, are electrically connected to the controller, and the controller is configured to control the rotation state of the rolling conveyor 22 according to the position of the cargo, so as to cooperate with the cargo handling mechanism to convey the cargo from the outside of the storage unit 2 into the storage unit 2 and to the outside of the cargo outlet 32. In the above scheme, according to the position system rolling conveying piece 22's of goods in storage unit 2 rotation state, for example in the material loading process, can be, when the goods just started to move, the rear end of goods on the direction of delivery K of goods is longer apart from the distance of goods export 32, can control rolling conveying piece 22's slew velocity is slower, treat that the goods will shift out storage unit 2, the rear end of goods on the direction of delivery K of goods is nearer apart from the distance of goods export 32, can control rolling conveying piece 22 rising speed, so that the goods more smoothly shifts out storage unit 2.

The structure of the robot arm 5 and the traveling frame 6 will be described with reference to fig. 1. Referring to fig. 1, as mentioned above, the robot arm 5 is movable relative to the storage unit 2, and the robot arm 5 is configured to move the goods by its own movement. That is, the robot arm 5 is used to transport the goods from the outside of the storage unit 2 into the storage unit 2 and to the outside of the goods outlet 32 via the storage unit 2 when the robot arm 5 moves relative to the storage unit 2.

In addition, the robot 5 is disposed corresponding to the storage unit 2, and illustratively, two robots 5 may be disposed corresponding to each storage unit 2, and the two robots 5 are symmetrically disposed on both sides of the storage unit 2 in the horizontal direction. The present application is not limited thereto, and the number of robot arms 5 may be other and may be located at other positions. The robot arm 5 may extend in the conveying direction of the goods, and in general, the moving direction of the robot arm 5 may be in the horizontal direction.

Specifically, the movable element 51 on the mechanical arm 5 can move to different positions relative to the mechanical arm 5, and when the movable element 51 is arranged on the conveying path of the goods in a blocking manner, the movable element 51 can push the goods to move. When the movable element 51 is not positioned on the conveying path of the goods, that is, the movable element 51 is positioned outside the conveying path of the goods, the movement of the mechanical arm 5 does not interfere with the goods.

In the embodiment of the present application, the movable member 51 is disposed at an end of the robot arm 5 away from the traveling frame 6. For example, when the robot arm 5 moves relative to the storage unit 2, the end of the robot arm 5 provided with the movable member 51 moves from the end of the storage unit 2 away from the cargo outlet 32 to the cargo outlet 32.

In addition to the movable push rod 52, the movable element 51 may be extended or shortened while rotating, for example, to be positioned on the conveying path of the goods or not. Further, the movable push rods 52 are provided in an even number and are respectively disposed at both sides of the storage unit 2. This allows for uniform application of force to the cargo.

Fig. 7 is an exploded view of a partial structure of a connection between a traveling rack and a slide rail in a cargo handling device according to an embodiment of the present disclosure. Referring to fig. 7, the fixing of the walking frame 6, for example, the support frame body 61 and the support frame 1, may be achieved by providing a slide rail 63 on the support frame 1, for example. In this embodiment, the support 1 includes the slide rail 63, and the extending direction of the slide rail 63 is parallel with the conveying direction K of the goods, and the support frame body 61 is disposed on the slide rail 63 and can move relative to the support 1 along the slide rail 63. The slide rail 63 may be installed on an outer side portion of the storage unit located lowermost.

In addition, the bracket 1 further comprises a sliding block 64 matched with the sliding rail 63, and the sliding block 64 can slide in the sliding rail 63 in a reciprocating mode. The bottom end of the support frame body 61 is provided with a connecting plate 611, the connecting plate 611 is connected to one side of the sliding block 64 departing from the sliding rail 63, and the sliding block 64 can drive the support frame body 61, namely the walking frame 6, to move along the sliding rail 63. The slider 64 can be driven by the second driving device to linearly move along the slide rail 63.

In the embodiment of the present application, as mentioned above, the second driving device of the driving assembly is disposed on the support 1, and the second driving device is electrically connected to the controller to drive the robot arm 5 to move relative to the storage unit 2 under the control of the controller.

The second driving means may comprise, for example, a motor, a reducer, a driving shaft, a sprocket, a chain, and the like. Wherein, the output shaft of the motor is connected with the driving shaft through the reducer, the chain wheel is connected with the driving shaft, the chain is tensioned on the chain wheel, and the sliding block 64 is connected with the chain. Thus, the motor drives the driving shaft to rotate through the speed reducer, the driving shaft drives the chain wheels to rotate, the chain tensioned between the chain wheels generates linear reciprocating displacement, and the sliding block 64 is driven to move on the sliding rail 63.

Referring to fig. 7, in order to prevent the walking frame 6 from colliding with the structure on the bracket 1, which may cause the bracket 1 to shake, the control assembly of the present application is further provided with a second position sensor 92, and the second position sensor 92 is electrically connected with the controller. The second position sensor 92 is used for detecting the position of the walking frame 6 relative to the support 1, and the controller is used for controlling the moving state of the walking frame 6 relative to the support 1 according to the position detected by the second position sensor 92.

In the above-mentioned solution, the second position sensor 92 is provided to detect the position of the walking frame 6 relative to the support 1, and when the walking frame 6 moves to the position corresponding to the second position sensor 92, the controller may adjust the moving state of the walking frame 6 in time according to the information of the second position sensor 92, for example, control the walking frame 6 to stop moving, that is, the speed of the walking frame 6 relative to the support 1 is zero, avoid the occurrence of collision event, and prevent the support frame body 61 of the walking frame 6 from moving out of the support 1. Thereby making the cargo-handling device 100 highly stable and safe.

In the embodiment of the present application, referring to fig. 7, in order to cooperate with the second position sensor 92, the walking frame 6 is further provided with a detecting member 65, and two end portions of the detecting member 65 may respectively extend toward the front upright 121 and the rear upright 122 on two sides of the walking frame 6. The second position sensor 92 is located at a position corresponding to the detecting member 65. And the controller is configured to control the traveling frame 6 to stop moving when the traveling frame 6 moves to a position where the detecting member 65 faces the second position sensor 92.

The detecting member 65 may be disposed on a connecting plate 611 at the bottom end of the support frame 61, and fixed relative to the slider 64, for example. In addition, as an alternative, the second position sensor 92 is a photoelectric sensor, and the detecting member 65 includes a light blocking member that can block the light blocking member disposed in front of the position sensor.

Taking the situation shown in fig. 7 as an example, when the supporting frame body 61 moves towards the cargo inlet 31 of the front side Q, the mechanical arm 5 and the cargo are driven to extend towards the cargo inlet 31, and the detecting member is driven to move towards the direction close to the second position sensor 92, when the detecting member is located at the side of the second position sensor 92, it is considered that the traveling frame 6 has reached the limit position, and then the detecting member continues to move leftwards, so that there is a risk of collision with the front upright 121, and at this time, the controller controls the traveling frame 6 to stop moving. Similarly, when the support frame 61 is moved in the direction of the rear side H of the cargo outlet 32, the description thereof is omitted.

In the embodiment of the present application, as described above, in order to further improve the loading success rate of the cargo handling apparatus 100, it is also necessary to monitor the moving state of the movable member 51 relative to the robot arm 5.

Referring to fig. 1 and 6, at least one of the robot arms 5 is provided with a detection component 3, and the detection component 3 is used for detecting a position state of the movable element 51, where the position state of the movable element 51 includes at least one of a position of the movable element 51 relative to the robot arm 5 and a position of the movable element 51 relative to the cargo. As described above, the second driving device is used for driving the traveling frame 6 to move relative to the bracket 1, and the detection assembly 3 and the second driving unit are electrically connected to the controller, and the controller is used for controlling the moving state of the traveling frame 6 according to the position state of the movable member 51.

In the embodiment of the present application, in the case where a plurality of robot arms 5 are provided in the cargo-handling device 100, the detection unit 3 may be provided to correspond to at least some of the movable members 51 of the robot arms 5. In other words, as shown in fig. 1, the detecting unit 3 may be provided for each robot arm 5, or the detecting unit 3 may be provided for some of the robot arms 5.

By providing the detection device 3, the position of the movable member 51 with respect to the robot arm 5 and the position of the movable member 51 with respect to the cargo can be monitored. For example, if the detection component 3 detects that the movable element 51 is located on the output path of the cargo, a control operation, such as controlling the moving state of the traveling frame 6, may be performed as required. Or, if the detecting component 3 detects that the end of the mechanical arm 5 has not reached the rear side of the cargo, the movable member 51 may be controlled to be in the folded position as required, so as to avoid interference with the cargo.

Specifically, the controller may send a control command to the movable element 51, so that the movable element 51 is changed from being not blocked on the conveying path of the goods (corresponding to the folded state of the movable push rod 52) to being blocked on the conveying path of the goods (corresponding to the unfolded state of the movable push rod 52), or the loading operation of the cargo handling device 100 is stopped, and the like, thereby effectively avoiding the situation of failure of the loading operation and improving the loading efficiency of the cargo handling device 100. Alternatively, the controller may send a control command to the movable element 51 to enable the movable element 51 to continue to maintain the state of not being placed on the cargo conveying path K.

Referring to fig. 1 and 6, in the embodiment of the present application, the detecting assembly 3 includes a first position detecting sensor 34, in order to better detect the position of the movable element 51, the first position detecting sensor 34 is disposed at an end portion of the robot arm 5, and the first position detecting sensor 34 corresponds to the unfolding position or the folding position of the movable push rod 52. In the drawings of the present application, the first position detection sensor 34 is described as corresponding to the folded position of the movable push rod 52, but the present application is not limited thereto, and the first position detection sensor 34 may be corresponding to the unfolded position of the movable push rod 52. In fig. 6, the first position detection sensor 34 is provided at an end portion of the robot arm 5, and when the movable element 51 is in the folded position, that is, when the movable push rod 52 is rotated to the vertical position, the first position detection sensor 34 can detect the position, that is, when the movable element 51 is in the position where the attachment/detachment operation is not possible, the first position detection sensor 34 can detect the position. The controller can perform corresponding control according to the detected information. Illustratively, the first position detection sensor 34 is a photosensor or a touch switch.

In addition, in the embodiment of the present application, the number of the moving members 51 may be multiple, the multiple moving members 51 are respectively and symmetrically disposed on two horizontal sides of the storage unit 2, and each of the moving members 51 is correspondingly provided with one first position detection sensor 34. Corresponding to the case where two robot arms 5 are provided in fig. 1 and 6, each robot arm 5 is provided with a movable member 51, and the end of each robot arm 5 is provided with a first position detecting sensor 34.

In the state shown in fig. 6, the end of the mechanical arm 5 on the left side of the drawing and the end of the mechanical arm 5 on the right side of the drawing are both provided with the first position detection sensor 34, and the movable element 51 on the left side is in the folded state, so that the first position detection sensor 34 on the left side sends the detected information that the movable element 51 is in the folded state to the controller; the movable element 51 on the right side is in the expanded state, and the first position detection sensor 34 on the right side transmits information that the movable element 51 on the right side is in the expanded state to the controller.

It should be noted that, the state of the movable member 51 in the extended state mentioned in the present application means that the movable push rod 52 is in the horizontal state; the condition that the movable piece 51 is in the folded state means that the movable push rod 52 is in the vertical state and the cargo cannot be loaded and unloaded.

It should be understood that, in the above control process, when the movable push rod 52 is in the folded state, it can be detected by the first position detecting sensor 34 and sent to the controller, and the controller controls the moving state of the walking frame 6 as required. When the movable pushing rod 52 is in the unfolded state, for example, when the movable pushing rod 52 is horizontal or rotated to a position between the folded and unfolded state, it is considered that the movable pushing rod 52 can still perform the loading operation, and therefore, the controller will not adjust the moving state of the walking frame 6.

In the present embodiment, in order to prevent the movable piece 51 from interfering with the cargo when the movable piece does not reach the rear side of the cargo, the position of the end of the robot arm 5 with respect to the cargo needs to be detected. Referring to fig. 6, the detecting assembly 3 may further include a second position detecting sensor 35, the second position detecting sensor 35 is disposed on the arm 5, and a position of the second position detecting sensor 35 corresponds to a position of the movable member 51, and the second position detecting sensor 35 is configured to detect whether the movable member 51 is located outside an end portion of the cargo.

The second position detection sensor 35 and the movable element 51 are located at the same position of the robot arm 5 in the conveyance direction of the cargo. For example, the second position detection sensor 35 may be located at an end portion of the robot arm 5 on a side of the robot arm 5 near the cargo so as to detect a relative position of the movable member 51 at the end portion of the robot arm 5 and the cargo. It is to be understood that the second position detection sensor 35 may be located at the bottom or top of the robot arm 5, or the like, as long as it can detect whether the movable piece 51 at the end of the robot arm 5 is located at the rear side of the cargo. The second position detection sensor 35 is also a photosensor or a contact switch, similar to the first position detection sensor 34.

Fig. 8 is a schematic view of another structure of the cargo handling device according to the first embodiment of the present application. Fig. 9 is a schematic structural diagram of a walking frame and a mechanical arm of another structure of the cargo handling device according to an embodiment of the present application. The cargo handling device 500 shown in fig. 8 and 9 is obtained by modifying the structure of the robot arm, the moving part, and the detecting element on the basis of the cargo handling device 100 shown in fig. 1, and the rest is the same as the cargo handling device 100 shown in fig. 1, and only the modified part will be described in detail below, and the rest will not be described again since the detailed description is given above.

In the embodiment of the present application, the movable members may also be multiple, that is, the movable members 505 may be disposed on the traveling frame in both directions along the cargo conveying direction K. Referring to fig. 8 and 9, unlike the structure shown in fig. 1, the robot 501 has a long length, and the support frame 61 is connected to an intermediate position of the robot 501, so that the robot 501 has two ends facing the goods outlet 503 and the goods inlet 502, respectively, a first end and a second end, and a movable member 505 is correspondingly connected to each of the two ends of the robot 501.

Specifically, the plurality of movable members 505 may include a first movable member 53 and a second movable member 54, where the first movable member 53 and the second movable member 54 are respectively disposed at two opposite ends of the same mechanical arm 501 along the extending direction, that is, at a first end and a second end of one mechanical arm. The first movable member 53 is disposed at a second end of the robot arm 501, and is configured to push the goods from the outside of the storage unit 504 into the storage unit 504 when the robot arm 501 moves relative to the storage unit 504; the second movable member 54 is disposed at a first end of the robot arm 501, and is configured to push the goods from the inside of the storage unit 504 to the outside of the goods outlet 503 when the robot arm 501 moves relative to the storage unit 504.

At least one of the first movable member 53 and the second movable member 54 is provided with the detection element 3. Illustratively, the first movable member 53 and the second movable member 54 are respectively provided with the detection component 3. In the above-described cargo handler 500, the cargo enters the storage unit 504 through the cargo outlet 503, and one end of the robot arm 501 may protrude outside the cargo outlet 503. And one end of the mechanical arm 501, which can extend out of the goods outlet 503, is provided with a first movable member 53.

It should be noted that, when the first movable member 53 is in the extended position, the second movable member 54 is in the extended position or the folded position, specifically, the first movable member 53 may push the goods outside the storage unit into the storage unit, and the second movable member 54 is located at the other end of the mechanical arm 501, and the state of the second movable member 54 does not affect the first movable member 53. When the second movable member 54 is in the extended position, the first movable member 53 is in the folded position, specifically, the second movable member 54 may push the goods in the storage unit 504 to the outside of the storage unit 504, and at this time, the first movable member 53 is in the folded position, so as to avoid affecting the output operation of the goods.

As another possible way, the goods enter the storage unit 504 from the side of the storage unit 504 opposite to the goods outlet 503, and the storage unit 504 has the goods inlet 502 disposed opposite to the goods outlet 503. In this case, the movable member 505 may be disposed at an end of the robot arm 501, and the end of the robot arm 501 where the movable member 505 is disposed has a movable range from the outside of the cargo inlet 502 to the cargo outlet 503. It is understood that the movable member 505 may be disposed at one end of the robot arm 501, or may be disposed at both ends of the robot arm 501 as shown in fig. 8.

The moving stroke of the robot arm 501 in the conveying direction K of the goods is greater than or equal to the length of the storage unit 504 in the direction, and the movable member 505 is used to push the goods from the outside of the goods inlet 502 to the outside of the goods outlet 503 via the storage unit 504 when the robot arm 501 moves relative to the storage unit 504.

In the embodiment of the present application, the movable range of the movable member 505 relative to the storage unit 504 is from the outer side of the cargo inlet 502 to the cargo outlet 503; and when the movable piece 505 is positioned outside the cargo inlet 502, the distance between the movable piece 505 and the cargo inlet 502 is greater than or equal to the length of the cargo in the cargo conveying direction K.

It is understood that, in the case that the movable member 505 includes the first movable member 53 and the second movable member 54, the connection manner of the first movable member 53 and the second movable member 54 with the mechanical arm 501 is similar to the connection manner of the movable member 51 in the cargo handling device 100 of fig. 1, for example, the movable member 505 may also be a movable push rod, a first end of the movable push rod is connected to the mechanical arm 501, a second end of the movable push rod can rotate around the rotating shaft, and when the movable push rod is located at the unfolding position, the movable push rod can abut against a side end of the cargo and push the cargo with the movement of the mechanical arm 501. The respective rotation axes of the first movable member 53 and the second movable member 54 are parallel to the conveying direction of the goods, and the like.

Next, several processes of loading and unloading the cargo with the cargo-handling device 100, 500 of the present application will be described, for example, the cargo-handling device 100 is taken as an example for description, and the loading and unloading manner of the cargo-handling device 500 is similar to that, and will not be described again here. In the present application, it should be noted that, no matter from which port of the storage unit the goods enter the storage unit, the goods are conveyed from the goods outlet to the outside of the storage unit.

In the above-described scheme, the case where the goods enter from the goods outlet 32 or the case where the goods enter from the side opposite to the goods can be classified into one storage unit according to the difference of the goods entrance ports. It is understood that one storage unit 2 here may be any one of the storage units 2 in the cargo handling apparatus 100. In the following, possible loading and unloading schemes in a memory unit 2 are described for two cases.

Fig. 10 is a schematic view of a cargo handling manner of one storage unit in the cargo handling apparatus according to the first embodiment of the present application, and fig. 11 is a schematic view of another cargo handling manner of one storage unit in the cargo handling apparatus according to the first embodiment of the present application. It should be noted that, in these figures, the goods in the storage unit 2 are shown by dotted lines, and the situation before the goods enter the storage unit 2 is shown by solid lines, wherein, the solid arrow indicates the direction of the goods entering the storage unit 2; the case where the goods are sent out from the storage unit 2 is indicated by a single-dot chain line, where a single-dot chain line arrow indicates a direction in which the goods are sent out from the storage unit 2, and reference numeral "J" indicates that the goods enter the storage unit, and reference numeral "C" indicates that the goods are sent out from the storage unit.

First is the case of cargo entering from the cargo outlet 32. As shown in fig. 10, the goods can enter the storage unit 2 from the goods outlet 32 of the storage unit 2, and the goods are conveyed to the outside of the storage unit 2 through the goods outlet 32 of the same storage unit 2. Wherein the rolling transfer element 22 is bidirectionally rotatable about its own axis of rotation. The goods enter the storage unit 2 through the goods outlet 32, and the goods output through the goods outlet 32 specifically means: when the rolling conveyor 22 is rotated in a direction away from the goods outlet 32, goods are conveyed into the storage unit 2 via the goods outlet 32; for the goods output, the goods are transported from the storage unit 2 to the outside of the goods outlet 32 when the rolling conveyor 22 is rotated in the direction toward the goods outlet 32.

Of course, for such cargo handling as described above, the end of the storage unit 2 opposite the cargo outlet 32 may be a closed end; alternatively, the end of the storage unit 2 opposite the goods outlet 32 may also be provided with a stop structure 36, the stop structure 36 being adapted to abut the goods. This prevents the cargo from falling from the side opposite to the cargo outlet 32.

Secondly, it is the case that the cargo enters from the side opposite to the cargo outlet 32.

In the above scheme, the cargo loading and unloading device is adopted for automatic loading or unloading, the rolling conveying member rotates to generate traction force on the cargo, so that the cargo can be conveyed into the storage unit from the outer side of the storage unit for automatic unloading by controlling the rotating state of the rolling conveying member 22, and the cargo in the storage unit is conveyed to the outer side of the cargo outlet 32 for automatic loading. In the process, the goods are not required to be loaded and unloaded manually, so that the automation degree is higher, and the operation efficiency is higher.

Specifically, taking the example of loading the transfer robot 200, the transfer robot 200 approaches the cargo handling device and reaches a predetermined loading position. The rolling transfer member 22 may be controlled to rotate toward the goods outlet 32, so as to generate a traction force on the goods toward the goods outlet 32, and the goods may move toward the pallet 205 of the transfer robot 200 under the traction force, thereby performing the loading operation.

In the embodiment of the present application, before controlling the rolling transfer element 22 to rotate in the direction toward the goods outlet 32 according to the goods loading and unloading control command to convey the goods from the storage unit 2 to the outside of the goods outlet 32, the method further includes: the rolling conveyor 22 is controlled to rotate in a direction away from the cargo outlet 32 to transport cargo from the cargo outlet 32 into the storage unit.

Specifically, the example of unloading the cargo robot will be described. The transfer robot 200 approaches the cargo handler and reaches a preset unloading position. The rolling conveyor 22 can be controlled to rotate in a direction away from the goods outlet 32 to generate a traction force on the goods toward the side away from the goods outlet 32, and the goods are moved by the pallet 205 of the transfer robot 200 into the goods outlet 32 and into the storage unit 2 under the traction force to discharge the transfer robot 200.

In other examples, controlling the rotation state of the rolling conveyor according to the cargo handling instruction to cooperate with the cargo handling mechanism to transport the cargo outside the storage unit 2 to the outside of the cargo outlet 32 via the inside of the storage unit 2 includes:

the rotating state of the rolling transmission member 22 is controlled according to at least one of the position of the goods in the storage unit and the moving speed of the goods, so as to cooperate with the goods carrying mechanism to convey the goods outside the storage unit to the outside of the goods outlet 32 through the storage unit.

In the above-mentioned solution, the rotation state of the rolling conveyor 22 is controlled according to the position of the goods in the storage unit, for example, the loading of the material robot is taken as an example for explanation. When the goods just start to move, the distance from the rear end part of the goods to the goods outlet 32 is long, the rotating speed of the rolling conveying member 22 can be controlled to be slow, when the goods are to be moved out of the storage unit, the distance from the rear end part of the goods to the goods outlet 32 is close to 0, and the rolling conveying member 22 can be controlled to be fast, so that the goods can be moved out of the storage unit and smoothly enter the goods plate 205 of the transfer robot 200. The position of the goods in the storage unit can here be detected by a first position sensor 91 according to the first embodiment.

The rolling state of the rolling conveyor 22 is controlled according to the moving speed of the goods, for example, the moving speed of the goods can be controlled within a proper range, so as to avoid the situation that the goods cannot be completely moved out of the storage unit or the speed is too high when the goods are moved out of the storage unit. It should be understood that the rotation state of the rolling conveyor 22 may be controlled according to the position of the goods in the storage unit; or the rotation state of the rolling conveyor 22 according to the control of the moving speed of the goods; or simultaneously controls the rotation state of the rolling conveyor 22 according to both the position of the goods in the storage unit and the moving speed of the goods.

The speed of movement of the robot arm, similarly to the speed of rotation of the roller conveyor 22, directly positively affects the speed of movement of the load. The position of the robotic arm relative to the storage unit also affects the position of the cargo relative to the storage unit.

In addition, as mentioned above, the movable member can rotate to different positions relative to the mechanical arm to unfold or fold, and when the movable member is in the unfolded state, the mechanical arm can drive the goods to move, so that the moving state of the mechanical arm is controlled, so that the mechanical arm and the rolling transfer member 22 together transport the goods outside the storage unit to the outside of the goods outlet 32 via the inside of the storage unit, further comprising:
