Description

Technical Field

[0001] This invention relates to the field of logistics transportation technology, and in particular to a logistics cargo transfer and transportation device. Background Technology

[0002] Logistics is a core component of supply chain activities. It is the planning, control, and management process for the efficient flow and storage of goods, services, and related information from production sites to consumption sites at the lowest cost to meet customer needs. Centered on warehousing, it promotes the synchronization of production and market through transportation, storage, and distribution, covering the entire process from raw materials and semi-finished products to finished products. To ensure the safe, timely, and cost-effective transfer of goods, transportation relies on vehicles such as trains, trucks, and airplanes; while at warehouse loading points, automated conveyor systems are used to assist in cargo transfer and loading operations to save time and manpower.

[0003] During transportation, the backward and forward tilting forces generated by inertia during the start and stop of conveying can seriously threaten the stability of the conveyor, easily causing cargo tipping accidents and posing significant safety hazards. At the same time, traditional lateral clamping methods, which rely on unidirectional clamping force, often cause excessive compression on the sides of the cargo, which can easily lead to deformation or damage to the packaging. Deformed packaging loses its protective function for the contents, and in subsequent transportation processes, vibration and collisions can easily cause the goods themselves (such as precision components, fragile items, etc.) to be scratched, broken, or malfunction, directly causing economic losses. Summary of the Invention

[0004] The purpose of this invention is to solve the problems raised in the prior art, and to propose a logistics cargo transfer and transportation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a logistics cargo transfer and conveying device, including a conveying vehicle body, an installation frame fixedly installed on the top of the conveying vehicle body, and a movable frame slidably connected to the inner wall of the installation frame, and two positioning and clamping mechanisms provided on the inner wall of the movable frame.

[0006] Both of the aforementioned positioning and gripping mechanisms include gripping plates disposed above the conveyor body. The two gripping plates are controlled to grip the goods first and then tilt, thereby offsetting the forward and backward inertia during the conveying movement by tilting the goods.

[0007] The side wall of the clamping plate has a through groove, and the inner wall of the through groove is provided with an auxiliary support mechanism. The auxiliary support mechanism includes a telescopic support plate provided on the side wall of the clamping plate, which automatically supports the bottom of the goods when the clamping plate tilts while clamping the goods, thereby reducing the clamping force on the goods.

[0008] Furthermore, the positioning and clamping mechanism includes a first movable plate, and a cross rod is fixedly connected through the interior of the first movable plate. A sliding plate is slidably connected to the outer wall of the cross rod, and a fixing ring is fixedly connected to the end of the sliding plate away from the first movable plate. A first spring is fixedly connected to the side of the fixing ring facing the sliding plate. A second movable plate is fixedly connected to the bottom of the first movable plate, and a movable rod is slidably connected through the inner wall of the second movable plate. A locking claw is fixedly connected to the end of the movable rod, and a second spring is fixedly connected to the side of the locking claw facing the movable rod. A fixing block is fixedly connected to the bottom of the locking claw, and a limit link is rotatably connected to the side wall of the fixing block. The outer wall of the sliding plate is rotatably connected to the outer wall of the clamping plate, and a sliding hole is provided through the side wall of the clamping plate. A curved sliding groove is provided on the outer wall of the movable rod.

[0009] Furthermore, the inner wall of the mounting frame is rotatably connected to a bidirectional screw, the interior of the movable frame is rotatably connected to the outer wall of the threaded rod through a thread, the inner wall of the movable frame is rotatably connected to a bidirectional screw, and the interiors of the two first movable plates are rotatably connected to the outer wall of the bidirectional screw through a thread.

[0010] Furthermore, the end of the first spring away from the fixed ring is fixedly connected to the side wall of the sliding plate, a protrusion is fixedly connected inside the second moving plate, the outer wall of the protrusion is slidably connected to the inner wall of the curved groove, the end of the second spring away from the locking claw is fixedly connected to the side wall of the second moving plate, and the inner walls of the two locking claws are locked and correspond to each other.

[0011] Furthermore, the inner walls of the corresponding sliding holes of the two clamping plates are slidably connected to a balance bar, and the end of the limiting link away from the fixed block is slidably connected to the outer wall of the limiting link, with the side walls of the two clamping plates corresponding to each other.

[0012] Furthermore, the auxiliary support mechanism includes a movable plate, and a stop plate is slidably connected to the inner wall of the movable plate. A third spring is fixedly connected to one end of the stop plate located inside the movable plate. An installation groove is provided on the side wall of the clamping plate, and a rotating shaft is rotatably connected to the inside of the installation groove via a torsion spring. An L-shaped plate is fixedly connected to the outer wall of the rotating shaft, and a connecting frame is slidably connected to one end of the outer wall of the L-shaped plate. A fourth spring is fixedly connected to one end of the L-shaped plate located inside the connecting frame. One end of the telescopic support plate is fixedly connected to the outer wall of the connecting frame. An L-shaped rod is fixedly connected to the end of the movable plate away from the stop plate, and a fifth spring is fixedly connected to the side wall of the L-shaped rod.

[0013] Furthermore, the outer wall of the movable plate is slidably connected to the inner wall of the through groove, the end of the third spring away from the abutment is fixedly connected to the inner wall of the movable plate, the end of the movable plate away from the abutment corresponds to the outer wall of the end of the L-shaped plate, the end of the fourth spring away from the L-shaped plate is fixedly connected to the inner wall of the connecting frame, and the end of the fifth spring away from the L-shaped rod is fixedly connected to the side wall of the clamping plate.

[0014] Furthermore, a motor is fixedly installed on the side wall of the movable frame, and one end of the bidirectional screw is fixedly connected to the output shaft of the motor.

[0015] Compared with existing technologies, the above solution has the following advantages:

[0016] 1. By clamping the goods against the side wall of the packaging with two clamping plates, the placement of the goods is corrected. At the same time, the movement of the conveyor body will cause several balance bars to contact and abut against the other side of the goods, thus completing the three-sided positioning and clamping function of the goods. This avoids problems such as skewing and misalignment of the goods on the shelves or in the warehouse. The range of movement between the two clamping plates can accommodate goods of different widths and lengths. Its clamping range covers the specifications of most standard corrugated cardboard boxes in the logistics center, improving the versatility of the device.

[0017] 2. The fixed block drives one end of the limiting linkage to move, causing the balance bar to move away from the fixed block. At the same time, the balance bar drives the connection between the two clamping plates and the sliding hole to rotate, causing the two clamping plates and several balance bars to tilt the goods at an angle. Then the motor stops driving, and the goods are clamped. The conveyor body then moves to transport the goods to the designated position. During the start and stop of the conveyor body, the goods will be subjected to a large forward and backward inertia. By tilting the goods during the transport process, the inertia can be reduced, reducing the possibility of the goods shaking or falling, and improving the stability and safety of the transportation process.

[0018] 3. By pressing the L-shaped plate with the movable plate, the L-shaped plate drives the telescopic pallet to rotate around the pivot point via the connecting frame. Then, the telescopic pallet flips to the bottom of the clamping plate, at which point it extends and retracts. Next, the movable plate pops outward, and its end presses against the end of the L-shaped plate to achieve a limit. At this time, the telescopic pallet is located at the bottom of the clamping plate and contacts the bottom of the goods, thus providing support. This avoids the need for two clamping plates and several balance bars to achieve multi-faceted support, and avoids the excessive pressure on the sides of the goods caused by the traditional unidirectional clamping force, which can lead to packaging deformation.

[0028] Example 1, please refer to Figures 1-4 A logistics cargo transfer and conveying device includes a conveyor body 1, a mounting frame 2 fixedly installed on the top of the conveyor body 1, and a movable frame 4 slidably connected to the inner wall of the mounting frame 2. Two positioning and clamping mechanisms 6 are provided on the inner wall of the movable frame 4. A bidirectional screw 5 is rotatably connected to the inner wall of the mounting frame 2. The interior of the movable frame 4 is rotatably connected to the outer wall of the threaded rotating rod 3 through a thread. The bidirectional screw 5 is rotatably connected to the inner wall of the movable frame 4. A motor 10 is fixedly installed on the side wall of the movable frame 4. One end of the bidirectional screw 5 is fixedly connected to the output shaft of the motor 10.

[0029] Both positioning and clamping mechanisms 6 include clamping plates 612 mounted above the conveyor body 1. The two clamping plates 612 are controlled to first clamp the goods and then tilt, using the tilting of the goods to counteract the forward and backward tilting inertia during conveying. Each positioning and clamping mechanism 6 includes a first moving plate 601, with a crossbar 602 fixedly connected through its interior. A sliding plate 603 is slidably connected to the outer wall of the crossbar 602, and a fixing ring 604 is fixedly connected to the end of the sliding plate 603 away from the first moving plate 601. A first spring 605 is fixedly connected to the side of the fixing ring 604 facing the sliding plate 603. The bottom of 01 is fixedly connected to a second movable plate 606, and the inner wall of the second movable plate 606 is slidably connected to a movable rod 607. The end of the movable rod 607 is fixedly connected to a locking claw 609, and the side of the locking claw 609 facing the movable rod 607 is fixedly connected to a second spring 608. The bottom of the locking claw 609 is fixedly connected to a fixing block 610, and the side wall of the fixing block 610 is rotatably connected to a limit link 611. The outer wall of the sliding plate 603 is rotatably connected to the outer wall of the clamping plate 612, and the side wall of the clamping plate 612 is provided with a sliding hole 613. The outer wall of the movable rod 607 is provided with a curved sliding groove 614.

[0030] Furthermore, the interiors of the two first moving plates 601 are rotatably connected to the outer wall of the bidirectional screw 5 via threads. The end of the first spring 605 away from the fixed ring 604 is fixedly connected to the side wall of the sliding plate 603. The interior of the second moving plate 606 is fixedly connected to a protrusion, and the outer wall of the protrusion is slidably connected to the inner wall of the curved slide groove 614. The end of the second spring 608 away from the locking claw 609 is fixedly connected to the side wall of the second moving plate 606. The inner walls of the two locking claws 609 are locked to each other. The inner walls of the two clamping plates 612 and the corresponding sliding holes 613 are slidably connected to a balance bar 9. The end of the limiting link 611 away from the fixed block 610 is slidably connected to the outer wall of the limiting link 611. The side walls of the two clamping plates 612 are corresponding.

[0031] More specifically, in nodes of the logistics network such as warehouses and distribution centers, receiving goods from the previous link such as trucks, airplanes, or the previous sorting machine, and automatically transporting them to the corresponding next exit or loading area according to preset destination and location information, requires the use of logistics cargo transfer and conveying devices. That is, a driving vehicle driven by electric power can be controlled to move along a designated route. The positioning and clamping mechanism 6 is used to clamp and move the goods. First, the driving conveyor body 1 is moved to the goods working area. Since the drive component for controlling the rotation of the threaded rotating rod 3 is installed inside the mounting frame 2 (not shown in the figure), the control threaded rotating rod 3 rotates and drives the moving frame 4 to slide up and down along the inner wall of the mounting frame 2 so that the clamping plate 612 moves to a position equal to the height of the goods. At the same time, the conveyor body 1 moves so that the two clamping plates 612 move to the sides of the goods.

[0032] Next, the output is transmitted through the drive motor 10. As the output shaft drives the bidirectional screw 5 to rotate, the bidirectional screw 5, due to its bidirectional thread design, causes the two first moving plates 601 to move relative to each other. The first moving plates 601 then drive the cross bar 602 to move synchronously. At this time, the sliding plate 603 clamps the plate 612, which moves synchronously with the cross bar 602. During the relative displacement, the two clamping plates 612 slide along the outer wall of several balance bars 9. The balance bars 9 passing through the two clamping plates 612 ensure that they are always in completely corresponding positions. After the two clamping plates 612 approach each other and move to a specified distance, their opposite sides will contact the goods. The outer wall of the goods is squeezed to achieve a clamping state. The goods in the logistics warehouse are all packaged with corrugated cardboard. During the clamping process of the two clamping plates 612, their side walls will completely fit against the side walls of the goods packaging to correct the placement of the goods. At the same time, the movement of the conveyor body 1 will cause several balance bars 9 to contact and abut against the other side of the goods, thereby completing the three-sided positioning and clamping function of the goods, avoiding problems such as skewing and misalignment of the goods on the shelves or in the warehouse. Through the range of movement between the two clamping plates 612, it can meet the needs of goods with different widths and lengths. Its clamping range covers the specifications of most standard corrugated cardboard boxes in the logistics center, improving the versatility of the device.

[0033] After the two gripping plates 612 have finished gripping the goods, the rotation of the bidirectional screw 5 will cause the two first moving plates 601 to continue to move relative to each other. At this time, the position of the gripping plates 612 will not change. Then the first moving plate 601 will drive the cross bar 602 to slide along the inside of the sliding plate 603. Then the first spring 605 will be compressed. At the same time, the first moving plate 601 will drive the second moving plate 606 to move. Then the second moving plate 606 will drive the locking claw 609 to move synchronously through the movable rod 607. Then the two opposing locking claws 609 will press against each other and lock together. Then the locking claws 609 can no longer move. Then the first moving plate 601 will drive the cross bar 602 to slide along the outer wall of the movable rod 607. Since the inner wall of the second moving plate 606 is fixedly connected to the protrusion that is slidably connected to the inner wall of the curved slide groove 614, the movable rod 607 will be squeezed by the protrusion through the curved slide groove 614 and rotate. Then it will drive the locking claw 609 to rotate synchronously.

[0034] Next, when the clamping claw 609 rotates, it will drive one end of the limiting link 611 to move through the fixed block 610. At this time, the other end of the limiting link 611 will squeeze the balance bar 9, causing the balance bar 9 to move away from the fixed block 610. At the same time, the balance bar 9 will drive the connection between the two clamping plates 612 and the sliding hole 613 to rotate, so that the two clamping plates 612 and several balance bars 9 will cause the goods to tilt at an angle. Then the motor 10 stops driving, and the clamping state of the goods is completed. Then the movement of the conveyor 1 will transport the goods to the designated position. During the process of the conveyor 1 starting to transport and stopping after transport, the goods will be subjected to a large forward and backward inertia. By tilting the goods during the transport process, the inertia can be reduced, reducing the possibility of the goods shaking or falling automatically, and improving the stability and safety of the transportation process.

[0035] Example 2, please refer to Figures 1-6 Based on Embodiment 1, in this embodiment, the side wall of the clamping plate 612 is provided with a through groove 7, and the inner wall of the through groove 7 is provided with an auxiliary support mechanism 8. The auxiliary support mechanism 8 includes a telescopic support plate 808 provided on the side wall of the clamping plate 612, which automatically supports the bottom of the goods when the clamping plate 612 tilts while clamping the goods, thereby reducing the clamping force on the goods.

[0036] Furthermore, the auxiliary support mechanism 8 includes a movable plate 801, and a stop plate 802 is slidably connected to the inner wall of the movable plate 801. A third spring 803 is fixedly connected to one end of the stop plate 802 located inside the movable plate 801. An installation groove 11 is provided on the side wall of the clamping plate 612, and a rotating shaft 804 is rotatably connected to the inside of the installation groove 11 via a torsion spring. An L-shaped plate 805 is fixedly connected to the outer wall of the rotating shaft 804, and a connecting frame 806 is slidably connected to one end of the outer wall of the L-shaped plate 805. A fourth spring 807 is fixedly connected to one end of the L-shaped plate 805 located inside the connecting frame 806. One end of the telescopic support plate 808 is fixedly connected to the connecting frame. The outer wall of 806 has an L-shaped rod 809 fixedly connected to the end of the movable plate 801 away from the abutment plate 802, and a fifth spring 810 fixedly connected to the side wall of the L-shaped rod 809. The outer wall of the movable plate 801 is slidably connected to the inner wall of the through groove 7. The end of the third spring 803 away from the abutment plate 802 is fixedly connected to the inner wall of the movable plate 801. The end of the movable plate 801 away from the abutment plate 802 corresponds to the end of the outer wall of the L-shaped plate 805. The end of the fourth spring 807 away from the L-shaped plate 805 is fixedly connected to the inner wall of the connecting frame 806. The end of the fifth spring 810 away from the L-shaped rod 809 is fixedly connected to the side wall of the clamping plate 612.

[0037] More specifically, during the process of the two clamping plates 612 clamping the goods, the bottom of the clamping plate 612 is in contact with the surface of the shelf. At this time, the telescopic pallet 808 is squeezed and retracted. Then, the goods will first contact the end of the abutment plate 802, and then squeeze the abutment plates 802 on both sides, causing the abutment plates 802 to slide towards the inner wall of the movable plate 801. Then the third spring 803 will be compressed. Next, the movable plate 801 will stretch the fifth spring 810 through the L-shaped rod 809, and at the same time, its end will press against the end of the L-shaped plate 805. After the clamping plate 612 completes clamping the goods and tilts, the abutment plate 802 will slide into the inside of the through groove 7. At this time, there is a gap between the bottom of the clamping plate 612 and the shelf.

[0038] The L-shaped plate 805 is pressed by the movable plate 801, causing the L-shaped plate 805 to rotate around the pivot 804 via the connecting frame 806. The telescopic pallet 808 then flips to the bottom of the clamping plate 612, at which point it extends and retracts. The movable plate 801 then pops outwards, its end pressing against the end of the L-shaped plate 805 for positioning. At this point, the telescopic pallet 808, located at the bottom of the clamping plate 612, contacts the bottom of the goods, thus achieving positioning. It provides support to prevent the goods from falling off during transport. It also avoids the need for two clamping plates 612 and several balance bars 9 to provide multi-faceted support, thus preventing the traditional unidirectional clamping force from excessively squeezing the sides of the goods and causing packaging deformation. After the goods are released after transport, the telescopic pallet 808 is squeezed by the shelf and slides into the bottom groove of the clamping plate 612. At the same time, the fourth spring 807 is squeezed, so as not to affect the release of the goods.

[0039] The working principle of this invention is as follows: First, the conveyor body 1 is moved to the cargo working area. Since the drive assembly for controlling the rotation of the threaded rod 3 is installed inside the mounting frame 2 (not shown in the figure), the threaded rod 3 is rotated to drive the moving frame 4 to slide up and down along the inner wall of the mounting frame 2, so that the clamping plate 612 moves to a position at the same height as the cargo. At the same time, the conveyor body 1 moves so that the two clamping plates 612 move to the positions on both sides of the cargo.

[0040] Then, as the drive motor 10 outputs power to rotate the bidirectional screw 5, the two first moving plates 601 undergo relative displacement. The first moving plates 601 then drive the cross bar 602 to move synchronously. At this time, the sliding plate 603 clamps the plate 612, which moves synchronously with the cross bar 602. During the relative displacement, the two clamping plates 612 simultaneously slide along the outer wall of several balance bars 9. The balance bars 9 passing through the two clamping plates 612 ensure that they are always in a completely corresponding position. When the two clamping plates 612 approach each other, they contact and compress the goods, achieving a clamping state for the goods in the logistics warehouse. The goods in the system are all packaged with corrugated cardboard. During the process of clamping the goods with two clamping plates 612, their side walls will completely fit against the side walls of the goods packaging, thereby correcting the placement of the goods. At the same time, the movement of the conveyor body 1 will cause several balance bars 9 to contact and abut against the other side of the goods, thus completing the three-sided positioning and clamping function of the goods, avoiding problems such as skewing and misalignment of the goods on the shelves or in the warehouse. Through the range of movement between the two clamping plates 612, it can meet the needs of goods of different widths and lengths. Its clamping range covers the specifications of most standard corrugated cardboard boxes in the logistics center, improving the versatility of the device.

[0041] After the two gripping plates 612 have finished gripping the goods, the rotation of the bidirectional screw 5 will cause the two first moving plates 601 to continue to move relative to each other. At this time, the position of the gripping plates 612 will not change. Then the first moving plates 601 will drive the cross bar 602 to slide along the inside of the sliding plate 603. Then the first spring 605 will be compressed. Then the second moving plate 606 will drive the locking claw 609 to move synchronously through the movable rod 607. Then the two opposing locking claws 609 will press against each other and lock together. Then the first moving plate 601 will drive the cross bar 602 to slide along the outer wall of the movable rod 607. Since the inner wall of the second moving plate 606 is fixedly connected with a protrusion that is slidably connected to the inner wall of the curved slide groove 614, the movable rod 607 will be squeezed by the protrusion through the curved slide groove 614 and rotate. Then it will drive the locking claw 609 to rotate synchronously.

[0042] Next, when the clamping claw 609 rotates, it will drive one end of the limiting link 611 to move through the fixed block 610. At this time, the other end of the limiting link 611 will squeeze the balance bar 9, causing the balance bar 9 to move away from the fixed block 610. At the same time, the balance bar 9 will drive the connection between the two clamping plates 612 and the sliding hole 613 to rotate, so that the two clamping plates 612 and several balance bars 9 will cause the goods to tilt at an angle. Then the motor 10 stops driving, and the clamping state of the goods is completed. Then the movement of the conveyor 1 will transport the goods to the designated position. During the process of the conveyor 1 starting to transport and stopping after transport, the goods will be subjected to a large forward and backward inertia. By tilting the goods during the transport process, the inertia can be reduced, reducing the possibility of the goods shaking or falling automatically, and improving the stability and safety of the transportation process.

[0043] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0044] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
