Description

Technical Field

[0001] This utility model relates to the field of transfer and conveying technology, and in particular to a high-height pallet stacking warehouse transfer vehicle. Background Technology

[0002] Post-processing of engineered wood panels includes processes such as panel screening, cooling, and stacking, which are now automated. The panel stacking process involves using a stacker crane to initially stack the continuously fed panels. The basic principle is that the input momentum of the panels causes them to fall onto a designated stacking platform. The platform descends by the height of one panel after each input panel, until it reaches a specified height, at which point a stack of panels of the designated height is formed. The maximum stack height is determined by the height difference between the panel input mechanism and the lowest point of the stacking platform, typically ranging from 1 to 1.5 meters. The pre-stacked panels are then transferred to a warehouse for storage. To improve warehouse space utilization, these pre-stacked panels are further stacked into larger stacks, such as 6 meters high, during warehouse storage.

[0003] However, the initial stacks of pallets typically weigh around 3 tons each, which is quite heavy. Furthermore, these stacks are collections of freely stacked panels. If high-height stacking were possible at every storage point in the warehouse, considering the equipment investment cost, only freely movable stacking machinery could be considered. Currently, no such stacking machinery can accomplish this task. Therefore, the prevailing approach is to install a fixed high-height stacker downstream of the initial stacker, stacking the initial pallets into a single high-height stack, and then transporting the entire high-height stack to a designated storage point for direct storage. However, the resulting high-height stacks weigh over 10 tons and consist of numerous freely stacked panels. The panels, especially those in the lower and middle sections, are highly susceptible to bending and deformation, and the risk of the stack tipping over is also high. This places higher demands on the load-bearing capacity and stability of the transfer equipment, which existing equipment cannot meet. Therefore, a specially designed and manufactured high-height pallet stack storage and transfer vehicle is needed to accomplish this task, leading to this invention. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tall pallet stacking warehouse transfer vehicle with good support capacity and stable transfer process.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a high-height pallet stacking and transfer vehicle, including a longitudinal base vehicle, the longitudinal base vehicle including a longitudinal body, three transversely arranged longitudinal support platforms fixed on the longitudinal body, the three longitudinal support platforms respectively forming support in the length direction of the pallet, a transverse transport vehicle installed between adjacent longitudinal support platforms, and a longitudinal traveling device installed on the longitudinal body; the transverse transport vehicle including a transverse body, a vertically movable transverse support platform installed on the transverse body, a lifting drive device between the transverse support platform and the transverse body, and a transverse traveling device installed on the transverse body.

[0006] As a preferred technical solution, the lifting drive device includes three lifting components arranged along the transverse direction. The transverse support platform is fixedly installed on the lifting components. Lifting transmission sleeves are rotatably installed on the transverse vehicle body corresponding to the lower part of each lifting component. A lifting transmission screw that cooperates with the lifting transmission sleeve is fixedly provided at the lower part of the lifting component. The three lifting transmission sleeves are connected to a lifting drive unit.

[0007] As a preferred technical solution, the lifting drive includes a lifting transmission worm gear fixedly disposed on each of the lifting transmission sleeves, a lifting transmission worm is respectively installed on the transverse vehicle body corresponding to each of the lifting transmission worm gears, and a universal connecting rod is connected between adjacent lifting transmission worms, wherein a lifting drive motor is provided between one of the lifting transmission worms or the universal connecting rod and the transverse vehicle body.

[0008] As a preferred technical solution, the lateral travel device includes lateral drive wheel sets installed at both ends of the lateral vehicle body, and a lateral drive motor is installed between each lateral drive wheel set and the lateral vehicle body; a lateral support wheel set is installed in the middle of the lateral vehicle body.

[0009] As a preferred technical solution, the longitudinal vehicle body is provided with transverse wheel rails corresponding to the transverse vehicle drive wheel set and the transverse vehicle support wheel set.

[0010] As a preferred technical solution, a lateral speed detector is installed on the lateral vehicle body.

[0011] As a preferred technical solution, the longitudinal walking device includes three longitudinal front wheels installed at the front end of the longitudinal vehicle body and three longitudinal rear wheels installed at the rear end of the longitudinal vehicle body, and the two longitudinal rear wheels located on both sides of the longitudinal section are respectively connected to longitudinal drive motors.

[0012] As a preferred technical solution, protective structures are fixedly provided on the longitudinal vehicle body at the longitudinal front side and longitudinal rear side of the three longitudinal vehicle support platforms, and the tops of the two protective structures are fixedly connected.

[0013] By adopting the above technical solution, a high-height pallet stacking and transfer vehicle includes a longitudinal base vehicle, which comprises a longitudinal body. Three transversely arranged longitudinal support platforms are fixed on the longitudinal body, each supporting the pallet along its length. A transverse transport vehicle is installed between adjacent longitudinal support platforms. A longitudinal traveling device is installed on the longitudinal body.

The three longitudinal support platforms on the longitudinal base vehicle support the high-height pallet stacks placed on it, all supporting the pallet along its length, which significantly reduces the deflection of the lower and middle sections of the pallet and improves the stability during longitudinal movement. The three longitudinal support platforms form two spaces for installing transverse transport vehicles, thus enabling two transverse transport vehicles to move tall stacks of plates in and out together. This results in a large support area, good support capacity, and good stability during lateral movement. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0025] like Figure 1 , Figure 2 and Figure 6 As shown, the high-height pallet stacking and storage transfer vehicle includes a longitudinal base vehicle 2, which comprises a longitudinal body 21. Three transversely arranged longitudinal support platforms 22 are fixedly mounted on the longitudinal body 21. Each of the three longitudinal support platforms 22 provides support along the length of the pallet. A longitudinal traveling device 3 is installed on the longitudinal body 21. Conventionally, man-made pallets are mostly rectangular, such as 2.4m × 1.2m. In this embodiment, the three longitudinal support platforms 22 provide three points of support for the high-height pallet stack 9, all along the length of the pallet. Compared to supporting along the width of the pallet, the span between adjacent longitudinal support platforms 22 is smaller, thus significantly reducing the deflection of the lower and middle parts of the pallet and providing better support capacity. The three supports achieve a good support span along the width of the pallet, forming a nearly large area of ​​support at the bottom of the high-height pallet stack 9, resulting in good stability during longitudinal travel.

[0026] In this embodiment, the descriptions of "longitudinal" and "lateral" refer to the corresponding longitudinal and lateral driving directions, which are essentially two mutually perpendicular directions in a plane. This embodiment is only used to explain the structural principle more clearly through the above definitions and is not intended to limit the scope of protection.

[0027] Preferably, protective structures 23 are fixedly installed on the longitudinal vehicle body 21 at the front and rear sides of the three longitudinal vehicle support platforms 22, and the tops of the two protective structures 23 are fixedly connected. This provides further protection for the tall stack of plates 9 and prevents accidents caused by the tall stack of plates 9 tipping over.

[0028] The longitudinal traveling device 3 is used to drive the longitudinal vehicle body 21 to travel longitudinally. In this embodiment, the longitudinal traveling device 3 includes three longitudinal front wheels 31 installed at the front end of the longitudinal vehicle body 21 and three longitudinal rear wheels 32 installed at the rear end of the longitudinal vehicle body 21. Two of the three longitudinal rear wheels 32 located on both sides of the longitudinal direction are respectively connected to longitudinal drive motors 33. In practical applications, three longitudinal wheel rails 34 are arranged corresponding to the longitudinal vehicle body 21, with the corresponding longitudinal front wheels 31 and longitudinal rear wheels 32 on the same longitudinal wheel rail 34 to form wheel rail guided travel. A total of six points of support are formed on the longitudinal vehicle body 21, resulting in good load-bearing capacity and good driving stability. Based on this, the purpose of driving travel is achieved by actively driving two of the longitudinal rear wheels 32. Of course, other means of actively driving two or three traveling wheels on the longitudinal wheel rails 34 are equivalent technical variations and should all be within the protection scope of the longitudinal traveling device 3.

[0029] like Figure 1 , Figure 2 and Figure 6 As shown, a transverse transport vehicle 4 is installed between adjacent longitudinal support platforms 22. Since there are three longitudinal support platforms 22, and they are used to support the plates along their length, each longitudinal support platform 22 can achieve a relatively small width. However, the transverse transport vehicle 4, which is set up in the space between adjacent longitudinal support platforms 22, can easily form a larger support surface. Therefore, when two transverse transport vehicles 4 move a tall stack of plates 9 together, they can still form a large area of ​​support at the bottom of the tall stack of plates 9, which has good support capacity and good stability during lateral movement.

[0030] like Figures 1 to 7 As shown, the transverse transport vehicle 4 in this embodiment includes a transverse vehicle body 41, on which a vertically movable transverse support platform 42 is installed. A lifting drive device is provided between the transverse support platform 42 and the transverse vehicle body 41, and a transverse traveling device 5 is installed on the transverse vehicle body 41. The lifting drive device facilitates the lifting of the tall stack of pallets 9, allowing it to leave the original support mechanism. After traveling to the designated position, the descending drive allows the tall stack of pallets 9 to sit on the designated support structure, completing the transport operation.

[0031] The lifting drive device described in this embodiment includes three lifting members 43 arranged along the transverse direction. A transverse carriage support platform 42 is fixedly mounted on each lifting member 43. Lifting transmission sleeves 44 are rotatably mounted on the transverse carriage body 41 corresponding to the lower part of each lifting member 43. A lifting transmission screw 45, which cooperates with the lifting transmission sleeve 44, is fixedly provided at the lower part of each lifting member 43. All three lifting transmission sleeves 44 are connected to a lifting driver. The lifting driver simultaneously drives the three lifting members 43 to lift and lower. The transverse carriage support platform 42 exhibits good lifting stability, which is beneficial for providing stable support for large-height stacks of plates 9. Furthermore, during support, the self-locking property of the lifting transmission screw 45 and the lifting transmission sleeve 44 ensures reliable support.

[0032] In this embodiment, where two transverse transport vehicles 4 jointly support a large stack of pallets 9, the lifting drive can be activated synchronously after both vehicles reach the designated position, achieving the synchronous lifting and lowering of the transverse support platform 42 on both vehicles. Reaching the designated position can be achieved by installing a positioning detector on the transverse vehicle body 41, which is easily obtained by those skilled in the art using existing technology and will not be elaborated further here.

[0033] Preferably, a lateral speed detector 55 is installed on the lateral vehicle body 41. By detecting the speed, the synchronicity of the lateral movement of the two lateral transport vehicles 4 is ensured, thereby further improving the stability of the transport process when the two vehicles jointly support a large stack of pallets 9. The lateral speed detector 55 can be implemented using an encoder or the like.

[0034] Preferably, the lifting drive includes lifting transmission worm gears 46 fixedly mounted on each of the lifting transmission sleeves 44, and lifting transmission worms 47 respectively mounted on the transverse car body 41 corresponding to each of the lifting transmission worm gears 46. Universal connecting rods 48 connect adjacent lifting transmission worms 47, and a lifting drive motor 49 is provided between one of the lifting transmission worms 47 or the universal connecting rod 48 and the transverse car body 41. Thus, the lifting drive can be arranged within the narrow space of the transverse car body 41, and the worm gear transmission also has self-locking properties, which can further improve the reliability of the transverse car support platform 42 in supporting the high-height stack of plates 9. Of course, conventionally, when the lifting drive motor 49 drives forward rotation, it drives the transverse car support platform 42 to rise; when it drives reverse rotation, it drives the transverse car support platform 42 to fall.

[0035] The lateral travel device 5 includes lateral drive wheel sets 51 installed at both ends of the lateral vehicle body 41, and a lateral drive motor 53 is installed between each lateral drive wheel set 51 and the lateral vehicle body 41; a lateral support wheel set 52 is installed in the middle of the lateral vehicle body 41. Both the lateral drive wheel set 51 and the lateral support wheel set 52 are preferably wheel sets composed of at least one pair of coaxial traveling wheels, and the traveling wheels on the same side are preferably on the same wheel rail. Therefore, the longitudinal vehicle body 21 is provided with lateral wheel rails 54 corresponding to the lateral drive wheel sets 51 and the lateral support wheel sets 52. Of course, in actual application scenarios, lateral wheel rails 54 are also correspondingly set in the direction of the high-height stacker 1 and the warehouse storage point, so that the lateral transport vehicle 4 maintains wheel rail guidance after entering and exiting the longitudinal base vehicle 2. This embodiment uses three sets of wheel sets in the lateral direction to form support, which also provides good load-bearing capacity and good driving stability.

[0036] like Figure 8 As shown, in practical application, the longitudinal wheel rails 34 for the longitudinal base carrier 2 are laid in the middle or at the edge of the warehouse, and these longitudinal wheel rails 34 extend to the vicinity of the high-height stacker 1. The output end of the high-height stacker 1 uses three chain conveyor devices 11 to form the final output and temporary support. The longitudinal base carrier 2 first stops in front of the chain conveyor device 11, where the transverse wheel rails 54 on it are aligned with the transverse wheel rails 54 set in the direction of the chain conveyor device 11. The two transverse transport vehicles 4 travel toward the chain conveyor device 11 until they are located in two spaces of the three chain conveyor devices 11. Then the transverse support platforms 42 on the two transverse transport vehicles 4 are simultaneously driven to rise, lifting the high-height stack 9 on the three chain conveyor devices 11 and making it leave the chain conveyor device 11. Then the two transverse transport vehicles 4 travel synchronously toward the longitudinal base carrier 2 until they are completely back on the longitudinal base carrier 2. The horizontal support platforms 42 on the two transverse transport vehicles 4 are simultaneously driven down, and the high-height stack 9 finally rests on the three horizontal support platforms 42. The longitudinal base vehicle 2 travels longitudinally to the corresponding position of the storage point, and the horizontal support platforms 42 on the two transverse transport vehicles 4 are driven up synchronously to lift the high-height stack 9 again. Then, the two transverse transport vehicles 4 travel synchronously towards the storage point until they reach the designated position. After that, the horizontal support platforms 42 on the two transverse transport vehicles 4 are driven down synchronously, and the high-height stack 9 sits on the support structure at the designated storage point. The two transverse transport vehicles 4 return to the longitudinal base vehicle 2 to carry out the transfer of the next high-height stack 9.

[0037] This embodiment employs a combination of longitudinal base carrier 2 and transverse transport vehicle 4 for transporting tall stacks of plates 9. The longitudinal base carrier 2 utilizes three longitudinal support platforms 22 to support the tall stacks of plates 9, all supporting them along the length of the plates. This significantly reduces deflection of the lower and middle sections of the plates and improves stability during longitudinal movement. The three longitudinal support platforms 22 form two spaces for mounting the transverse transport vehicles 4, allowing two transverse transport vehicles 4 to simultaneously move the tall stacks of plates 9 in and out. This provides a large support area, good support capacity, and good stability during lateral movement.
