Description

Technical Field

[0001] The invention belongs to the field of logistics transfer, in particular to a logistics transfer device. Background Art

[0002] Logistics is an industry that involves the entire process from the place of production to the place of consumption of goods, including transportation, warehousing, packaging, distribution, logistics information management and other links. The main purpose of logistics is to ensure that goods can be safely transported from the supply point to the demand point.

[0003] Logistics transshipment refers to the process of transporting goods from a starting point to a destination through different modes of transportation and service providers. It is included in the classification of logistics transportation. For example, in the case of long-distance transportation, large trucks are used for centralized loading and transportation. When arriving at the sorting point, the goods need to be unloaded from the large trucks and distributed to small trucks according to the region for distribution.

[0004] In traditional logistics transportation, all goods need to be taken out of large trucks and received by a conveyor belt or a forklift plus a pallet combination at the end of the truck. However, since large trucks are stacked with a large number of goods of different sizes and shapes, the goods are often taken out one by one by manual transportation, which not only consumes a lot of manpower, but also has low transportation efficiency.

[0005] To this end, the present invention provides a logistics transfer equipment. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a kind of logistics transfer equipment described in the present invention comprises a plurality of material-grabbing arms, which are arranged in parallel and equidistantly, a moving seat is installed on the top of the material-grabbing arm, the material-grabbing arm is composed of an upper force arm and a lower force arm, the upper force arm and the lower force arm are rotatably connected by a door shaft, the upper force arm and the moving seat are also rotatably connected by a door shaft, a steel cable capable of controlling the bending and rotation of the upper force arm and the lower force arm is arranged on the outer side of the moving seat, the plurality of moving seats are connected in series by a sliding rod, and two driving vehicles for driving the sliding rod to move are arranged on the outer side of the sliding rod;

[0008] Through the setting of the picking arm, after the truck stops, two driving vehicles are attached to the inner wall of the truck, so that the slide bar is horizontally propped up, and multiple picking arms are vertically set in the storage space of the truck. The upper force arm and the lower force arm can be controlled to bend by pulling the steel cable. The bent picking arm is located at the top, and then the picking arm is driven to move to the depth of the truck through the movement of the driving vehicle, and then the picking arm is lowered to return to the vertical shape. The bottom of the vertical picking arm is flush with the bottom surface of the truck. At this time, the driving vehicle drives the slide bar and multiple picking arms to move toward the exit, and the goods can be continuously pushed out of the truck. It only needs to use a conveyor belt or The forklift pallet combination can receive the goods. During the assembly stage of the equipment and the truck, the material-retrieving arm is folded, and the two driving carts can be placed at the lower position of the truck storage space. The driving wheels of the driving cart can be rotated at will, so that the driving cart can move arbitrarily on the inner wall of the truck. When the driving cart drives the material-retrieving arm to move upward and to the top, the material-retrieving arm is controlled to move along the direction of the truck. This setting facilitates the assembly and disassembly process of the equipment and the truck; through this setting, the function of mechanized handling of goods is realized, and the vertical material-retrieving arm can push logistics goods of various shapes. At the same time, the efficiency of pushing goods in batches is higher than that of manual handling.

[0009] Preferably, two suction cups are fixedly connected to the bottom of the lower force arm, and the openings of the suction cups face downward. A vacuum pump is fixedly connected to the middle of the lower force arm, and the negative pressure output end of the vacuum pump is connected to the two suction cups. During transportation, large trucks generally stack square goods and fill the entire storage space of the truck in order to increase the cargo volume, which makes it difficult to take the goods out during unloading. Through the setting of the suction cups, when encountering goods stacked too high, the picking arm is bent. At this time, the suction cups at the ends of the picking arm are horizontally set and facing the goods. The suction cups and the picking arm are driven by a driving vehicle to approach the top of the stacked goods, and the vacuum pump is started to generate negative pressure, thereby sucking the goods. After that, the driving vehicle controls the entire picking arm to move horizontally to drag the goods from the top of the stack outward, and then the picking arm is unbent and becomes vertical. , and turn off the negative pressure, which can not only separate some of the goods outward, but also reduce the height of the stacked goods. When the height is reduced to a certain extent, the entire equipment can be moved to the rear of the goods and push the goods to the exit as a whole, thereby effectively realizing the function of transferring the goods in the truck outward, and can deal with the problem of goods stacked too high and having no fulcrum. At the same time, when the picking arm is in a vertical state, start the vacuum pump to generate negative pressure at the bottom of the suction cup, thereby pulling the picking arm to straighten. At the same time, under the action of negative pressure, the lower force arm will be sucked to the bottom of the car box, and the upper force arm above will be restricted and cannot rotate in the opposite direction of the exit. In this way, when the picking arm is moving, the upper force arm above remains vertical, and the lower force arm below will be slightly bent, but due to the existence of negative pressure, the lower force arm fits with the bottom of the car box, thereby effectively pushing the goods to move in the direction of the exit.

[0010] Preferably, the bottom of the lower arm is bifurcated. The bottom of the lower arm consists of two bifurcated arms. The suction cup is fixedly connected to the bottom of the bifurcated arm. The length of the lower arm is greater than that of the upper arm. A pressing net is fixedly connected between the two bifurcated arms. If the sum of the widths of multiple lower arms is the same as the inner width of the truck, it will be difficult to observe the state of the goods at the rear during operation, which is not conducive to operation. Moreover, if the mass of the material taking arm is too large, it will also cause too heavy a burden on the two driving vehicles on both sides. By reducing the volume of the material taking arm, making the lower arm bifurcated, and keeping the pressing net in a straightened state, as the material taking arm moves, the goods can be pushed towards the exit, and at the same time, the overall situation of the truck compartment can always be observed, reducing operation errors. At the same time, the bifurcated method at the bottom of the lower arm allows the bifurcated arms of the lower arm to fully fit the inner wall of the compartment, while the parts above do not need to fit the compartment, which can reduce friction and thus use the power to push the goods.

[0011] Preferably, a plurality of moving platforms are fixedly connected to the outer side of the sliding rod. A support arm is fixedly connected between the plurality of moving platforms. The support arm is arranged parallel to the sliding rod. The two ends of the support arm are fixedly connected to the driving vehicle housing. By sleeving the sliding rod and the support arm with the moving platform and connecting the support arm to the driving vehicle, and the driving vehicle abuts against the inner wall of the compartment, the movement of multiple material taking arms can be controlled.

[0012] Preferably, a reduction motor is arranged at the lower part of one end of the sliding rod. The output end of the reduction motor is fixedly connected to a screw rod. The screw rod passes through a plurality of moving seats and is in transmission connection with the moving seats. A connecting platform is installed between the screw rod and the sliding rod. A connecting plate is fixedly connected between the reduction motor and the sliding rod. By driving the screw rod to rotate through the reduction motor, the horizontal movement of multiple material taking arms can be achieved, so that a small number of material taking arms can be used to push a large amount of goods out of the compartment. For example, first push the goods on the left outwards, and then drive the material taking arm to move to the right by driving the reduction motor to push the goods on the right outwards.

[0013] Preferably, a driving motor I is installed inside the moving seat. The output end of the driving motor I is fixedly connected to a winding roller. The top of the steel cable is fixedly connected to the winding roller. The steel cable passes through the middle part of the upper arm and is fixedly connected to the middle part of the lower arm. The steel cable passes through the upper arm and the lower arm. The position where the steel cable passes through the upper arm is at the middle part of the upper arm, and the position where the steel cable is fixed to the lower arm is also at the middle part. As the winding roller winds up the steel cable, the wound steel cable will first rotate and bend the lower arm below upwards, and then the upper arm rotates. The upper arm is restricted to rotate only to the horizontal state. The final state is that the upper arm and the lower arm are stacked on top of each other and remain in the horizontal state. At this time, the fixed position of the steel cable with the lower arm just coincides with the position where the steel cable passes through the upper arm. This is conducive to the horizontal movement of the equipment at the top inside the compartment and will not be blocked by the goods.

[0014] Preferably, an extension pipe is fixedly connected to the middle of the upper arm. The extension pipe is inclined, and both ends of the extension pipe are exposed on both sides of the upper arm. The steel cable passes through the extension pipe. The edges of the extension pipe are all set with smooth transitions. The steel cable passes through the extension pipe and slides in the extension pipe. At the same time, both ends of the extension pipe extend outwards, reducing the surface contact between the steel cable and the material-taking arm. Because if it directly passes through the material-taking arm, the steel cable will be close to the surface of the material-taking arm, which can reduce the wear of the steel cable and the material-taking arm.

[0015] Preferably, the bottom of the suction cup is made of elastic material. A separation net is fixedly connected to the bottom surface of the suction cup. The separation net is made of magnet material. A blocking block is fixedly connected to the bottom of the upper arm. The blocking block is used to limit the rotation of the lower arm. The suction cup fits with the bottom surface of the carriage. The traditional bottom surface of the carriage cannot be flat. The flexible suction cup can fit well with the carriage. By adjusting the suction force through a vacuum pump, the problem of insufficient power of the driving vehicle can be prevented. The magnet material separation net can prevent external goods from being sucked into the suction cup, and at the same time rely on magnetic adsorption to make the suction cup and the carriage fit, reducing the output power consumption of the vacuum pump.

[0016] Preferably, a plurality of metal balls are rotatably connected to the end faces of the reduction motor and the connecting platform. One end of the driving vehicle is connected with a traction rope, and the end of the traction rope is connected with a winding box for winding and releasing the traction rope. The reduction motor and the connecting platform will contact the carriage. In order to reduce friction, metal balls are used to roll-friction with the inner wall of the carriage. A driving motor II is arranged in the winding box. The rotation of the driving motor II can wind or release the traction rope. Winding the traction rope is used to provide a huge pulling force for the driving vehicle and the equipment. When encountering larger goods, the traction rope can be used to increase the power of the equipment. The winding box can be temporarily fixed outside the carriage.

[0017] Preferably, the support arm is divided into multiple sections. Adjacent sections of the support arm are connected by sleeves. The support arm is fixedly connected to the support arm by bolts. The sizes of the trucks used for materials are generally the same. After the equipment is adjusted, it can be used normally. When encountering a truck with a larger size, the distance that the support arm slides out of the sleeve can be adjusted to ensure that the driving vehicles at both ends fit with the inner wall of the carriage, improving the applicable range of the equipment. At the same time, during daily use, the overall length of the support arm can also be finely adjusted to ensure that the support arm can be firmly suspended in the carriage.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A logistics transfer equipment described in the present invention, through the setting of the material picking arm, after the truck stops, the two driving vehicles are attached to the inner wall of the truck, so that the sliding bar is horizontally propped up, and multiple material picking arms are vertically arranged in the storage space of the truck, and the upper force arm and the lower force arm can be controlled to bend by pulling the steel cable, and the bent material picking arm is located at the top, and then the material picking arm is driven to move to the depth of the truck through the movement of the driving vehicle, and then the material picking arm is lowered to return to the vertical shape, and the bottom of the vertical material picking arm is flush with the bottom surface of the truck. At this time, the driving vehicle can continuously push the goods out of the truck by driving the sliding bar and multiple material picking arms to move toward the exit. It is only necessary to use a conveyor belt or a forklift pallet combination outside the truck to receive the goods. Through this arrangement, the function of mechanized cargo handling is realized, and the vertical material picking arm can push logistics goods of various shapes, and the efficiency of pushing goods in batches is higher than that of manual handling.

[0020] 2. The logistics transfer equipment described in the present invention, through the setting of the suction cup, when encountering goods that are stacked too high, by bending the picking arm, the suction cup at the end of the picking arm is set horizontally and faces the goods, and the driving vehicle drives the suction cup and the picking arm to approach the top of the stacked goods, and starts the vacuum pump to generate negative pressure, thereby sucking the goods, and then the driving vehicle controls the entire picking arm to move horizontally, dragging the goods from the top of the stack outward, and then the picking arm is unbent to a vertical state, and the negative pressure is turned off, so that part of the goods can be separated outward and the height of the stacked goods can be reduced. When the height is reduced to a certain extent, the entire equipment can be moved. To the rear of the goods, and push the goods toward the exit as a whole, thereby effectively realizing the function of transferring the goods in the truck outward, and can deal with the problem of goods stacked too high and having no fulcrum. At the same time, when the picking arm is in a vertical state, start the vacuum pump to generate negative pressure at the bottom of the suction cup, thereby pulling the picking arm to straighten. At the same time, under the action of negative pressure, the lower force arm will be sucked to the bottom of the car body, and the upper force arm above will be restricted and cannot rotate in the opposite direction to the exit. In this way, when the picking arm is moving, the upper force arm above remains vertical, and the lower force arm below will be slightly bent, but due to the existence of negative pressure, the lower force arm fits against the bottom of the car body, thereby effectively pushing the goods to move toward the exit.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figures 1 to 5 As shown, a logistics transfer device according to an embodiment of the present invention comprises a plurality of material fetching arms 7, which are arranged in parallel and equidistantly, a movable seat 1 is installed on the top of the material fetching arm 7, the material fetching arm 7 is composed of an upper force arm 8 and a lower force arm 11, the upper force arm 8 and the lower force arm 11 are rotatably connected by a door shaft 10, the upper force arm 8 and the movable seat 1 are also rotatably connected by the door shaft 10, a steel cable 9 capable of controlling the bending and rotation of the upper force arm 8 and the lower force arm 11 is arranged on the outer side of the movable seat 1, the plurality of movable seats 1 are connected in series by a slide bar 4, and two driving vehicles 15 for driving the slide bar 4 to move are arranged on the outer side of the slide bar 4;

[0030] In traditional logistics transfer, all goods need to be taken out of large trucks and received by conveyor belts or forklifts plus pallets at the end of the trucks. However, since large trucks are stacked with a large number of goods of different sizes and shapes, they are often taken out one by one by manual handling, which not only consumes a lot of manpower but also has low handling efficiency. In addition, traditional logistics packages generally include square paper-shell packaging goods and flexible packaging goods of random shapes. For transportation stability, square-shaped goods are generally stacked neatly, while flexible packaging is stacked at the exit of the truck storage space. It is difficult to transfer goods out without manual handling.

[0031] In view of the above technical problems, in the present invention, through the provision of the material taking arm 7, after the truck stops, the two driving vehicles 15 are attached to the inner wall of the carriage, so as to horizontally support the sliding rod 4. A plurality of material taking arms 7 are vertically arranged in the carriage. By pulling the steel cable 9, the upper arm 8 and the lower arm 11 can be controlled to bend. After bending, the material taking arm 7 is located above the goods. Then, by moving the driving vehicle 15, the material taking arm 7 is driven to move deeper into the carriage. After that, the material taking arm 7 is lowered to return to the vertical shape. The bottom of the vertical material taking arm 7 is flush with the bottom surface of the carriage. At this time, the driving vehicle 15 drives the sliding rod 4 and a plurality of material taking arms 7 to move towards the exit, and the goods can be continuously pushed out of the carriage. It only needs to use a conveyor belt or a forklift pallet combination outside the carriage to receive the goods; during the equipment and carriage assembly stage, the material taking arm 7 is in a folded state, and the two driving vehicles 15 can be placed against the lower position of the carriage. The driving wheels of the driving vehicle 15 can rotate freely, so that the driving vehicle 15 can move arbitrarily on the inner wall of the carriage. When the driving vehicle 15 drives the material taking arm 7 to move upward to the top, then control the material taking arm 7 to move along the carriage exit direction. This setting facilitates the assembly and disassembly process of the equipment and the carriage; through this setting, the function of mechanized handling of goods is realized, and the vertical material taking arm 7 can push various shaped logistics goods. At the same time, the efficiency of batch pushing of goods is higher than that of manual handling;

[0032] It should be noted that in order for the equipment to work more smoothly, when stacking goods, it is necessary to ensure that there is a certain gap between the upper part and both sides of the goods and the inner wall of the cargo box, and there is also a certain gap between the goods, so that the equipment can move smoothly to the rear of the goods and thus push the goods to move.

[0033] Two suction cups 14 are fixedly connected to the bottom of the lower arm 11. The suction cups 14 open downward. A vacuum pump 12 is fixedly connected to the middle of the lower arm 11. The negative pressure output end of the vacuum pump 12 is communicated with the two suction cups 14;

[0034] During operation, in order to increase the cargo volume during transportation, large trucks generally stack square cargo and fill the entire truck box, which makes it difficult to take the cargo out during unloading. Through the setting of the suction cup 14, when encountering cargo that is stacked too high, the picking arm 7 is bent. At this time, the suction cup 14 at the end of the picking arm 7 is horizontally set and faces the cargo. The driving vehicle 15 drives the suction cup 14 and the picking arm 7 to approach the top of the stacked cargo, and the vacuum pump 12 is started to generate negative pressure, thereby sucking the cargo. Then the driving vehicle 15 controls the entire picking arm 7 to move horizontally, and the cargo is dragged out from the top of the stack. Then the steel cable 9 releases the picking arm 7. Under the action of gravity, the picking arm 7 is unbent and becomes vertical, and the negative pressure is turned off. In this way, part of the cargo can be separated outward and the height of the stacked cargo can be reduced. After moving a certain distance, the equipment is moved to the rear of the towed goods and the goods are pushed outward. When the height is lowered to a certain extent, the space above the goods is vacated, and the entire equipment can be moved to the rear of the goods and the goods are pushed toward the exit as a whole, thereby effectively realizing the function of transferring the goods in the car box outward, and can deal with the problem of goods stacked too high and having no fulcrum. At the same time, when the picking arm 7 is in a vertical state, the vacuum pump 12 is started to generate negative pressure at the bottom of the suction cup 14. Under the action of negative pressure, the lower force arm 11 will be sucked by the bottom surface of the car box, and the upper force arm 8 above will be restricted and cannot rotate in the opposite direction to the exit. In this way, during the movement of the picking arm 7, the upper upper force arm 8 remains vertical and the lower lower force arm 11 will be slightly bent. However, due to the existence of negative pressure, the lower force arm 11 fits with the bottom surface of the car box, thereby effectively pushing the goods to move toward the exit. It should be noted that, although the lower force arm 11 is sucked by the suction cup 14 and the bottom surface of the vehicle box, the driving force of the driving vehicle 15 when moving is much greater than the adsorption force of the suction cup 14, thereby smoothly pushing the movement of the goods.

[0035] The bottom of the lower force arm 11 is bifurcated, and the bottom of the lower force arm 11 is composed of two bifurcated arms 13. The suction cup 14 is fixedly connected to the bottom of the bifurcated arm 13. The length of the lower force arm 11 is greater than that of the upper force arm 8. An extrusion net 22 is fixedly connected between the two bifurcated arms 13.

[0036] During operation, if the combined width of multiple lower force arms 11 is the same as the inner width of the carriage, it will be difficult to observe the status of the goods at the rear during operation, which is not conducive to operation. Moreover, the mass of the material fetching arm 7 is too large, which will also cause too heavy a burden on the two driving vehicles 15. By reducing the volume of the material fetching arm 7, making the lower force arm 11 bifurcated, and simultaneously squeezing the mesh 22 into a straightened state, as the material fetching arm 7 moves, the goods can be pushed towards the exit, and the overall situation of the carriage can always be observed, reducing operation errors. At the same time, the bifurcated method at the bottom of the lower force arm 11 allows the bifurcated arms 13 of the lower force arm 11 to fully fit the inner wall of the carriage, while the upper components do not need to fit the carriage, which can reduce friction and thus facilitate the pushing of the goods. The length of the lower force arm 11 is greater than that of the upper force arm 8 so that after the lower force arm 11 is bent, the suction cup 14 at the bottom can protrude outwards, smoothly contact the goods and adsorb and drag them.

[0037] A plurality of moving platforms 20 are fixedly connected to the outer side of the sliding rod 4. A support arm 2 is fixedly connected between the plurality of moving platforms 20. The support arm 2 is arranged parallel to the sliding rod 4, and both ends of the support arm 2 are fixedly connected to the shell of the driving vehicle 15.

[0038] During operation, the moving platform 20 sleeved on the sliding rod 4 and the support arm 2, and at the same time, the support arm 2 is connected to the driving vehicle 15, and the driving vehicle 15 abuts against the inner wall of the carriage, so as to control the movement of the plurality of material fetching arms 7.

[0039] A speed reduction motor 6 is arranged at the lower part of one end of the sliding rod 4. The output end of the speed reduction motor 6 is fixedly connected to a screw rod 5. The screw rod 5 passes through a plurality of moving seats 1 and is threadedly connected to the moving seats 1. A connecting platform 3 is installed between the screw rod 5 and the sliding rod 4. The connecting platform 3 is fixedly connected to the support arm 2. A connecting plate is fixedly connected between the speed reduction motor 6 and the sliding rod 4.

[0040] During operation, the speed reduction motor 6 drives the screw rod 5 to rotate, so that the plurality of material fetching arms 7 can be horizontally moved. In this way, a small number of material fetching arms 7 can be used to push a large amount of goods out of the carriage. A small number of material fetching arms 7 also need to be arranged at equal intervals. By moving the material fetching arms 7 left and right, the goods in the cargo box are pushed outwards in multiple times.

[0041] A driving motor one is installed inside the moving seat 1. The output end of the driving motor one is fixedly connected to a winding roller. The top of the steel cable 9 is fixedly connected to the winding roller. The steel cable 9 passes through the middle of the upper force arm 8 and is fixedly connected to the middle of the lower force arm 11.

[0042] During operation, the steel cable 9 passes through the upper arm 8 and the lower arm 11. The position where the steel cable 9 passes through the upper arm 8 is in the middle of the upper arm 8, and the position where the steel cable 9 is fixed to the lower arm 11 is also in the middle. As the winding roller winds up the steel cable 9, the wound steel cable 9 will first rotate the lower arm 11 below upward and bend it. Then the upper arm 8 rotates. The upper arm 8 is restricted to rotate only to the horizontal state. The final form is that the upper arm 8 and the lower arm 11 are stacked on top of each other and remain in the horizontal state. At this time, the fixed position of the steel cable 9 on the lower arm 11 just coincides with the position where the steel cable 9 passes through the upper arm 8; this is beneficial for the equipment to move horizontally on the inner top of the carriage and will not be blocked by goods.

[0043] An extension pipe 18 is fixedly connected to the middle of the upper arm 8. The extension pipe 18 is inclined. Both ends of the extension pipe 18 are exposed on both sides of the upper arm 8. The steel cable 9 passes through the extension pipe 18;

[0044] During operation, the edges of the extension pipe 18 are all set with smooth transitions. The steel cable 9 passes through the extension pipe 18 and slides in the extension pipe 18. At the same time, both ends of the extension pipe 18 extend outwards, reducing the surface contact between the steel cable 9 and the material taking arm 7. Because if it directly passes through the material taking arm 7, it will cause the steel cable 9 to closely adhere to the surface of the material taking arm 7. This can reduce the wear of the steel cable 9 and the material taking arm 7.

[0045] The bottom of the suction cup 14 is made of an elastic material. A separation net is fixedly connected to the bottom surface of the suction cup 14. The separation net is made of a magnet material. A blocking block 21 is fixedly connected to the bottom of the upper arm 8. The blocking block 21 is used to limit the rotation of the lower arm 11;

[0046] During operation, the suction cup 14 fits with the bottom surface of the carriage. The traditional bottom surface of the carriage cannot be made flat. The suction cup 14 made of a flexible material can fit well with the carriage. The size of the suction force is adjusted through the vacuum pump 12 to prevent the problem of insufficient power of the driving vehicle 15. The separation net made of a magnet material can prevent external goods from being sucked into the suction cup 14. At the same time, it relies on magnetic adsorption to make the suction cup 14 fit with the carriage, reducing the output power consumption of the vacuum pump 12.

[0047] A plurality of metal balls are rotatably connected to the end faces of the reduction motor 6 and the connection table 3. One end of the driving vehicle 15 is connected to a traction rope 23. The end of the traction rope 23 is connected to a winding box 24 for winding and releasing the traction rope 23;

[0048] During operation, the reduction motor 6 and the connection table 3 will contact the carriage. In order to reduce friction, metal balls are used to roll and friction with the inner wall of the carriage. A driving motor two is arranged in the winding box 24. The rotation of the driving motor two can wind up or release the traction rope 23. Winding up the traction rope 23 is used to provide a huge pulling force for the driving vehicle 15 and the equipment. When encountering larger goods, the traction rope 23 can be used to increase the power of the equipment. The winding box 24 can be temporarily fixed outside the carriage.

[0049] The support arm 2 is divided into multiple segments, and adjacent segments of the support arm 2 are connected by a sleeve 16. The support arm 2 is fixedly connected to the support arm 2 by bolts;

[0050] During operation, the sizes of the carriages used for transportation are generally the same. After the equipment is adjusted, it can be used normally. When encountering a carriage with a larger size, the distance that the support arm 2 slides out of the sleeve 16 can be adjusted to ensure that the driving vehicles 15 at both ends are in contact with the inner wall of the carriage, improving the applicable range of the equipment. At the same time, during daily use, the overall length of the support arm 2 can also be finely adjusted to ensure that the support arm 2 can be firmly suspended in the carriage.

[0051] During operation, through the setting of the material taking arm 7, after the truck stops, the two driving vehicles 15 are attached to the inner wall of the truck, thereby horizontally supporting the sliding rod 4. Multiple material taking arms 7 are vertically arranged in the storage space of the truck. By pulling the steel cable 9, the upper force arm 8 and the lower force arm 11 can be controlled to bend. After bending, the material taking arm 7 is located at the top. Then, through the movement of the driving vehicle 15, the material taking arm 7 is driven to move deeper into the truck. After that, the material taking arm 7 is lowered to return to the vertical shape. The bottom of the vertical material taking arm 7 is flush with the bottom surface of the truck. At this time, the driving vehicle 15 drives the sliding rod 4 and multiple material taking arms 7 to move towards the exit, and the goods can be continuously pushed out of the truck. It only needs to use a conveyor belt or a forklift pallet combination outside the truck to receive the goods. During the assembly stage of the equipment and the truck, the material taking arm 7 is in a folded state, and the two driving vehicles 15 can be placed against the lower position of the storage space of the truck. The driving wheels of the driving vehicle 15 can rotate freely, so that the driving vehicle 15 can move arbitrarily on the inner wall of the truck. When the driving vehicle 15 drives the material taking arm 7 to move upward to the top, then control the material taking arm 7 to move along the direction of the truck. This setting facilitates the assembly and disassembly process of the equipment and the truck; through this setting, the function of mechanized cargo handling is realized, and the vertical material taking arm 7 can push various shaped logistics goods, and the efficiency of pushing goods in batches is higher than that of manual handling;

[0052] Through the setting of the suction cup 14, when encountering goods that are stacked too high, the picking arm 7 is bent. At this time, the suction cup 14 at the end of the picking arm 7 is set horizontally and faces the goods. The driving vehicle 15 drives the suction cup 14 and the picking arm 7 to approach the top of the stacked goods, and the vacuum pump 12 is started to generate negative pressure, so that the goods are sucked. Then the driving vehicle 15 controls the entire picking arm 7 to move horizontally, and the goods are dragged outward from the top of the stack. After that, the picking arm 7 is unbent and becomes vertical, and the negative pressure is turned off. In this way, part of the goods can be separated outward and the height of the stacked goods can be reduced. When the height is reduced to a certain extent, the entire device can be moved to the rear of the goods. The cargo is pushed toward the exit as a whole, thereby effectively realizing the function of transferring the cargo in the truck outward, and can deal with the problem of cargo being stacked too high and having no fulcrum. At the same time, when the picking arm 7 is in a vertical state, the vacuum pump 12 is started to generate negative pressure at the bottom of the suction cup 14, thereby pulling the picking arm 7 to become straight. At the same time, under the action of the negative pressure, the lower force arm 11 will be sucked with the bottom surface of the vehicle box, and the upper force arm 8 above will be restricted and cannot rotate in the opposite direction to the exit. In this way, during the movement of the picking arm 7, the upper force arm 8 above remains vertical, and the lower force arm 11 below will be slightly bent. However, due to the existence of negative pressure, the lower force arm 11 fits with the bottom surface of the vehicle box, thereby effectively pushing the cargo to move toward the exit.

[0053] If the width of multiple lower force arms 11 is the same as the inner width of the truck, it will be difficult to observe the state of the goods at the rear during operation, which is not conducive to operation. In addition, the mass of the material-grabbing arm 7 is too large, which will also cause the burden of the driving vehicles 15 on both sides to be too heavy. By reducing the volume of the material-grabbing arm 7, the lower force arm 11 is made into a forked shape, and the squeezing net 22 is in a straight state. In this way, as the material-grabbing arm 7 moves, the goods can be pushed to the exit, and the situation of the entire truck box can be observed all the time, reducing operational errors. At the same time, the forked bottom of the lower force arm 11 allows the forked arm 13 of the lower force arm 11 to fully fit with the inner wall of the box, and the upper parts are not used for fitting with the box, which can reduce friction, so that the power is used to push the goods.

[0054] The slide bar 4 and the support arm 2 are sleeved by the moving platform 20, and the support arm 2 is connected to the driving vehicle 15, and the driving vehicle 15 is against the inner wall of the vehicle box, so as to control the movement of the multiple material taking arms 7;

[0055] The screw rod 5 is driven to rotate by the reduction motor 6, so that the multiple material taking arms 7 can be moved horizontally, so that a large amount of goods can be pushed out of the vehicle box by controlling a small number of material taking arms 7. For example, the goods on the left side are pushed out first, and then the material taking arms 7 are controlled to move to the right by the reduction motor 6 to push the goods on the right side out;

[0056] The steel cable 9 passes through the upper arm 8 and the lower arm 11. The position where the steel cable 9 passes through the upper arm 8 is in the middle of the upper arm 8, and the position where the steel cable 9 is fixed to the lower arm 11 is also in the middle. As the winding roller winds up the steel cable 9, the wound steel cable 9 will first rotate and bend the lower arm 11 below upward, and then the upper arm 8 rotates. The upper arm 8 is restricted to rotate only to the horizontal state. The final form is that the upper arm 8 and the lower arm 11 overlap each other and remain in the horizontal state. At this time, the fixed position of the steel cable 9 on the lower arm 11 just coincides with the position where the steel cable 9 passes through the upper arm 8. This is beneficial for the equipment to move horizontally at the top inside the carriage and will not be blocked by goods.

[0057] The edges of the extension tube 18 are all set with smooth transitions to ensure that the insertion position of the steel cable 9 does not change. At the same time, both ends of the extension tube 18 extend outwards to reduce the surface contact between the steel cable 9 and the material taking arm 7. Because if it directly passes through the material taking arm 7, it will cause the steel cable 9 to closely adhere to the surface of the material taking arm 7. This can reduce the wear of the steel cable 9 and the material taking arm 7.

[0058] The suction cup 14 fits with the bottom surface of the carriage. The traditional bottom surface of the carriage cannot be flat. The suction cup 14 made of flexible material can fit well with the carriage. The size of the suction force is adjusted by the vacuum pump 12 to prevent the problem of insufficient power of the driving vehicle 15. The isolation net made of magnetic material can prevent external goods from being sucked into the suction cup 14. At the same time, it relies on magnetic adsorption to make the suction cup 14 fit with the carriage, reducing the output power consumption of the vacuum pump 12.

[0059] The reduction motor 6 and the connecting platform 3 will contact the carriage. In order to reduce friction, metal balls are used to roll and friction with the inner wall of the carriage. A driving motor two is arranged in the winding box 24. The rotation of the driving motor two can wind up or release the traction rope 23. Winding up the traction rope 23 is used to provide a huge pulling force for the driving vehicle 15 and the equipment. When encountering larger goods, the traction rope 23 can be used to increase the power of the equipment. The winding box 24 can be temporarily fixed outside the carriage.

[0060] The sizes of the trucks used for materials are generally the same. After the equipment is adjusted, it can be used normally. When encountering trucks with larger sizes, the distance that the support arm 2 slides out of the sleeve 16 can be adjusted to ensure that the driving vehicles 15 at both ends fit with the inner wall of the carriage, improving the applicable range of the equipment. At the same time, during daily use, the overall length of the support arm 2 can also be finely adjusted to ensure that the support arm 2 can be firmly suspended in the carriage.
