Description

[0001] Technical solution

[0002] This invention relates to the field of sponge processing, and more specifically to a sponge lifting and stacking system. Background Technology

[0003] Sponge is a porous elastic material. Commonly used sponges are made of foamed plastic polymers. They are relatively soft, have dense internal pores, and have a certain structural strength.

[0004] After foaming, the sponges are typically cut into uniform sizes for easy storage. These sponge blocks are then manually stacked together and sent to a warehouse for later use. This method is labor-intensive and easily contaminates the sponges, and has been gradually phased out.

[0005] Currently, in relatively modern factories, individual sponge blocks are typically transported to multi-story warehouses of equal height via a main conveyor. Each floor has a spare auxiliary conveyor to facilitate the entry and exit of sponges, resulting in high sponge storage costs and difficulty in fully utilizing storage space. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a sponge lifting and stacking system, which is ingeniously designed, easy to operate, and enables automatic stacking or removal of sponge blocks, thereby improving work efficiency.

[0007] The technical solution of the present invention: A sponge-lifting stacking system includes a storage rack, a transfer trolley, and a first stacking device. The transfer trolley is located at the front end of the storage rack, and at least one first stacking device is located at the front side of the storage rack. A gap is provided between the storage rack and the first stacking device to allow the transfer trolley to move. The first stacking device includes a frame, a conveying platform, a lifting part, a clamping part, and a telescopic part. The conveying platform is installed on the frame, and columns are respectively set on both sides of the conveying platform. The columns are installed on both sides of the frame. A lifting part is installed on the inner side of each column. The clamping part is installed on the lifting part through the telescopic part. The clamping parts on both sides clamp each other. When it is necessary to store sponge blocks, the first stacking device stacks the sponge blocks that are sequentially transported to the conveyor platform from top to bottom. After stacking to a set height, the conveyor platform transports the stacked sponge blocks to a transfer cart, which then transports the sponge blocks into the storage rack. When it is necessary to remove the sponge blocks, the above actions are reversed.

[0008] A second stacking device is also provided on one side of the storage rack, and a turnover platform is provided at one end of the second stacking device. The second stacking device has the same structure as the first stacking device.

[0009] A turnover platform is also provided at one end of the first stacking device.

[0010] The turnover platform is used to temporarily place unwanted stacked or removed sponge blocks. Once the required sponge blocks are placed or removed, the sponge blocks on the turnover platform are stacked back or removed.

[0011] The lifting mechanism includes a guide rail, a slider, a drive wheel, a tension wheel, a belt, a housing, and a drive motor. A drive wheel and two tension wheels are installed in the middle of the housing, with the two tension wheels located on either side of the drive wheel near the bottom. The drive motor is installed on the outside of the housing, driving the drive wheel. A guide rail is installed on the inside of the column. A slider is installed at the bottom of the housing, sliding on the guide rail. The belt is installed at both ends on the inside of the column, with the belt located outside the guide rail. The belt passes through the top and bottom of the housing and wraps around the outside of the drive wheel. The two tension wheels press against the outside of the belt from both sides. A telescopic mechanism is installed on the outside of the housing. Two lifting mechanisms, one upper and one lower, are slidably installed on each side of the column. Alternatively, the lifting unit may include a guide rail, a slider, a housing, a first telescopic cylinder, and a second telescopic cylinder. A guide rail is installed on the inner side of the column, and a slider is installed at the bottom of the housing. The slider slides on the guide rail. The first telescopic cylinder is designed to be installed below the housing, with its upper end connected to the lower end of the housing and its lower end fixed to the frame. Alternatively, the lifting unit may be designed with two sets installed on the same column, connected by a second telescopic cylinder. The upper end of the second telescopic cylinder connects to the lower end of the housing of the upper lifting unit, and its lower end connects to the upper end of the housing of the lower lifting unit. Telescopic components are installed on the outer sides of both sets of lifting units. The upper end of the first telescopic cylinder connects to the lower end of the housing of the lower lifting unit.

[0012] The telescopic part includes a long arm plate and a short arm plate. The inner end of the long arm plate is hinged to the housing of the upper lifting part, and the inner end of the short arm plate is hinged to the housing of the lower lifting part. The outer end of the short arm plate is hinged to the long arm plate near the middle. The middle of the inner end of the clamping plate is hinged to the outer end of the long arm plate. The upper end of the clamping plate is also connected to the housing of the upper lifting part through at least one connecting rod. One end of the connecting rod is hinged to the housing of the upper lifting part, and the other end of the connecting rod is hinged to the upper end of the clamping plate.

[0013] The distance between the two hinge points of the connecting rod is the same as that of the long arm plate. The distance between the hinge points of the connecting rod to the box and the long arm plate is the same as the distance between the hinge point of the connecting rod and the clamping plate to the outer end of the long arm plate and the hinge point of the clamping plate.

[0014] The clamping plate includes an upper clamping plate and a lower clamping plate. The upper clamping plate and the lower clamping plate are connected by a connecting brace. The middle of the connecting brace is hinged to the outer end of the long arm plate. The upper end of the connecting brace is fixedly connected to the back side of the upper clamping plate, and the lower end of the connecting brace is fixedly connected to the back side of the lower clamping plate. The other end of the connecting rod is hinged to the upper end of the connecting brace of the clamping plate.

[0015] The upper and lower clamping plates have several mounting holes on their working sides, and sensors are installed in these holes. The upper and lower clamping plates also have several protrusions on their surfaces.

[0016] Each side has two columns. The drive wheels of the upper lifting parts on the two columns on the same side are connected and driven by a synchronous shaft, sharing a single drive motor. The drive wheels of the lower lifting parts on the two columns on the same side are also connected and driven by a synchronous shaft, sharing a single drive motor.

[0017] The advantages of this invention are: 1. This invention is ingeniously designed and easy to operate, enabling automatic stacking or retrieval of sponge blocks, achieving fully automated warehousing and outbound operations, eliminating the need for manual handling, greatly reducing labor intensity, improving storage space utilization, and increasing work efficiency; 2. The stacking device in this invention achieves the clamping and lifting functions of the clamping plate by combining multiple sets of drive motors with a compact mechanical structure. Its stable and reliable power drive ensures the stability of the clamping plate in lifting the sponge block. The clamping plate has multiple protection devices, which can effectively prevent the risk of the sponge block falling due to mechanical failure, and improve the safety and reliability of the entire system operation.

[0026] See attached document Figure 1-8 A sponge-lifting stacking system includes a storage rack 10, a transfer vehicle 11, and a first stacking device 12. The transfer vehicle 11 is located at the front end of the storage rack 10, and at least one first stacking device 12 is also located at the front side of the storage rack 10. A gap is left between the storage rack 10 and the first stacking device 12 to allow the transfer vehicle 11 to move. The first stacking device 12 includes a frame 1, a conveying platform 2, a lifting part 3, a clamping part 4, and a telescopic part 5. The conveying platform 2 is installed on the frame 1. Columns 6 are respectively provided on both sides of the conveying platform 2. The columns 6 are installed on both sides of the frame 1. A lifting part 3 is installed on the inner side of each column 6. The clamping part 4 is installed on the lifting part 3 through the telescopic part 5. The clamping parts 4 on both sides clamp each other. When it is necessary to store sponge blocks 9, the first stacking device 12 stacks the sponge blocks 9 that are sequentially transported to the conveying platform from top to bottom. After stacking to a set height, the conveying platform transports the stacked sponge blocks 9 to the translation cart 11, and the translation cart 11 transports the sponge blocks 9 into the storage rack 10. When it is necessary to take out the sponge blocks 9, the above actions are reversed.

[0027] The storage rack includes several rectangular racks, each equipped with an independently controlled conveyor belt for receiving or outputting stacked sponge blocks. Storage racks are existing technology; for example, racks are disclosed in patent CN202110108919.2. This invention is briefly described below.

[0028] The translation cart moves left and right between storage racks and processing equipment such as sponge cutting machines to receive or transport sponge blocks. It performs corresponding work in accordance with different processing instructions. The translation cart can be equipped with a dedicated floor rail to ensure its smooth left and right movement. The translation cart also has an independent conveyor belt to receive or output sponge blocks. It uses a servo motor to drive the rollers to achieve left and right translation. The translation cart is also existing technology. This invention is briefly described.

[0029] In operation, the long strip of sponge is fed to a sponge cutting machine for cutting into smaller pieces. These smaller pieces are then conveyed to a conveyor platform on a first stacking device. The first stacking device clamps and lifts the first sponge piece, while the conveyor platform receives a second sponge piece. The first stacking device places the first sponge piece on top of the second, and then clamps and lifts both pieces together, awaiting the receipt of a third sponge piece. This process is repeated until three layers of sponge pieces are stacked, reaching the stacking height of a warehouse shelf. The conveyor platform of the first stacking device then conveys the three sponge pieces to a transfer cart, which then transports them to the corresponding shelves on the warehouse shelf. Removing the sponge pieces is simply the reverse process. This invention features an ingenious stacking method, stacking the sponge pieces from bottom to top, and removing them from underneath the stacked pieces.

[0030] A second stacking device 13 is also provided on one side of the storage rack 10. A turnover platform 8 is provided at one end of the second stacking device 13. The second stacking device 13 has the same structure as the first stacking device 12. A turnover platform 8 is also provided at one end of the first stacking device 12. The turnover platform 8 can be designed as a single conveying platform, a platform for a conveying and translating trolley, or a conveying platform for sponge processing equipment. The main purpose of the design is to address the requirement for the stacking or removal order of sponge blocks 9 of different thicknesses during the stacking or removal process. In this case, the turnover platform 8 is used to temporarily place the sponge blocks 9 that do not need to be stacked or removed. After the required sponge blocks are stacked or removed, the sponge blocks 9 on the turnover platform 8 are then stacked. For example, if a sponge storage cabinet stores three sponge blocks of different thicknesses, and it is necessary to remove the middle or top sponge block, the lower sponge blocks need to be removed as well. In this case, this device can clamp the middle or top sponge block, first transporting the bottom one or the two bottom blocks to the turnover platform, and then placing the required sponge block on the conveyor platform and transporting it to the transfer car. The transfer car then transports the sponge blocks to the corresponding processing equipment such as the sponge cutting machine according to the instructions, thus realizing the sponge block outbound sorting requirements.

[0031] The lifting unit 3 includes a guide rail 31, a slider 32, a drive wheel 33, a tension wheel 34, a belt 35, a housing 36, and a drive motor 37. A drive wheel 33 and two tension wheels 34 are installed in the middle of the housing 36, with the two tension wheels 34 located on either side of the drive wheel 33 near its bottom. The drive motor 37 is installed on the outer side of the housing 36, driving and connecting to the drive wheel 33. A guide rail 31 is installed on the inner side of the column 6. A slider 32 is installed at the bottom of the housing 36, sliding on the guide rail 31. The belt 35 is installed at both ends on the inner upper and lower sides of the column 6, with the belt 35 located outside the guide rail 31. The belt 35 passes through the upper and lower sides of the housing 36 and wraps around the outside of the drive wheel 33. The two tension wheels 34 press against the outside of the belt 35 from both sides. The telescopic unit 5 is installed on the outer side of the housing 36. The belt can be designed as a synchronous toothed belt, the drive wheel can be designed as a synchronous pulley, and the belt and synchronous pulley structure can also be designed as a gear and rack structure or a sprocket and chain structure. The drive motor can be designed as a servo motor or a stepper motor. Two lifting parts 3 are slidably installed on each of the columns 6 on each side.

[0032] Alternatively, the lifting unit may include a guide rail 31, a slider, a housing 36, a first telescopic cylinder 301, and a second telescopic cylinder 302. The guide rail 31 is installed on the inner side of the column, and a slider is installed on the bottom of the housing 36. The slider is slidably mounted on the guide rail 31. The first telescopic cylinder 301 is designed to be installed below the housing 36, with its upper end connected to the lower end of the housing 36 and its lower end fixed to the frame. The lifting unit is designed to have two sets installed on the same column, connected by the second telescopic cylinder 302. The upper end of the second telescopic cylinder 302 is connected to the lower end of the housing 36 of the upper lifting unit, and its lower end is connected to the upper end of the housing 36 of the lower lifting unit. Telescopic parts are designed to be installed on the outer sides of the two sets of lifting units. The upper end of the first telescopic cylinder is connected to the lower end of the housing of the lower lifting unit.

[0033] The telescopic part 5 includes a long arm plate 51 and a short arm plate 52. The inner end of the long arm plate 51 is hinged to the housing 36 of the upper lifting part 3, and the inner end of the short arm plate 52 is hinged to the housing 36 of the lower lifting part 3. The outer end of the short arm plate 52 is hinged to the long arm plate 51 near the middle. The inner end of the clamping plate part 4 is hinged to the outer end of the long arm plate 51 in the middle. The upper end of the clamping plate part 4 is also connected to the housing 36 of the upper lifting part 3 by at least one connecting rod 41. One end of the connecting rod 41 is hinged to the housing 36 of the upper lifting part 3, and the other end of the connecting rod 41 is hinged to the upper end of the clamping plate part 4.

[0034] The distance between the two hinge points of the connecting rod 41 is the same as that of the long arm plate 51. The distance between the hinge points of the connecting rod 41 and the housing and the long arm plate 51 is the same as the distance between the hinge point of the connecting rod and the clamping plate and the outer end of the long arm plate and the hinge point of the clamping plate. This consistent length design forms a parallelogram shape that can rotate at all four corners. This ensures that the clamping plate installation design always maintains vertical clamping, preventing tilting and ensuring stable and reliable clamping.

[0035] The clamping plate part 4 includes an upper clamping plate 42 and a lower clamping plate 43. The number of clamping plates can be designed in multiple sets as needed. The upper clamping plate 42 and the lower clamping plate 43 are connected by a connecting support 44. The middle of the connecting support 44 is hinged to the outer end of the long arm plate 51. The upper end of the connecting support 44 is fixedly connected to the back side of the upper clamping plate 42, and the lower end of the connecting support 44 is fixedly connected to the back side of the lower clamping plate 43. The other end of the connecting rod 41 is hinged to the upper end of the connecting support 44 of the clamping plate part 4.

[0036] The working sides of the upper clamping plate 42 and the lower clamping plate 43 are designed with several mounting holes 45, and sensors 46 are installed in the mounting holes 45. The sensor design ensures that the upper and lower clamping plates clamp the sponge block and transmits signals to the control unit. The control unit controls the drive motor to continue rotating for a certain number of revolutions, accurately controlling the clamping depth and ensuring the clamping force.

[0037] Two columns 6 are designed on each side. The drive wheels 33 of the upper lifting parts 3 on the two columns 6 on the same side are connected and driven by a synchronous shaft 7, sharing a single drive motor 37. Similarly, the drive wheels 33 of the lower lifting parts 3 on the two columns 6 on the same side are also connected and driven by a synchronous shaft 7, sharing a single drive motor 37. This design is for large sponge blocks with a large lateral length of the clamping plate. To ensure equipment stability, two columns are designed on each side for support. Correspondingly, an additional set of upper and lower lifting parts and telescopic parts is added to each side. Both sets are simultaneously supported and controlled from the back of the clamping plate, ensuring stability and reliability. Furthermore, the two upper lifting parts and two lower lifting parts on each side are connected to two drive wheels via a synchronous shaft and driven by the same drive motor, saving space and resulting in a compact structure.

[0038] The upper clamping plate 42 and the lower clamping plate 43 are each designed with several protrusions 47. The design of several protrusions ensures that the clamping plates can effectively hold the sponge block.

[0039] In use, the first sponge block is conveyed onto the conveying platform of this device. The device controls the lifting and lowering of the telescopic and clamping parts via a lifting mechanism, lowering the sponge block to both sides. The telescopic part then controls the clamping parts to clamp the sponge block from both sides. After clamping, the lifting parts on both sides rise synchronously, lifting the first sponge block. At this point, the second sponge block is conveyed onto the conveying platform. The device controls the first sponge block to stack on top of the second sponge block. The device then repeats the clamping action, clamping and lifting the bottom sponge block. Once the third sponge block is conveyed onto the conveying platform, the stacking action is repeated. This process is repeated until the optimal stacking height is reached. The stacked sponge blocks are then conveyed to a designated storage rack. When the stacked sponge blocks need to be removed for machining and cutting, the stacking process is reversed. This stacking device can stack sponge blocks higher than the device itself, occupying minimal space while still creating relatively high stacks for temporary storage needs.

[0040] The telescopic part of this device can adopt existing telescopic mechanisms such as telescopic cylinders, and the clamping part adopts clamping plates. One end of the telescopic cylinder is installed on the outside of the box of the lifting part, and the other end of the telescopic cylinder is connected to the back side of the clamping plate. The front side of the clamping plate is used to clamp the sponge block. Multiple telescopic cylinders can be designed as needed. This conventional structure of installing telescopic cylinders on the lifting part requires the installation of telescopic cylinders and other components such as the air circuit. Moreover, one telescopic cylinder cannot meet the clamping needs of a large sponge block, such as a sponge block weighing more than 200 kilograms. The installation design is also relatively complicated. This invention is described simply.

[0041] In the specific implementation of the clamping action provided by this invention, the telescopic action of the telescopic part requires the upper and lower lifting parts on the same column to control the cross extension and retraction of the long arm plate and the short arm plate, so that the clamping plate installed at the outer end of the long arm plate will perform the telescopic action. This structure does not require other telescopic mechanisms to assist the action. It can be achieved simply by the upper and lower lifting parts cooperating with the cross action of the long arm plate and the short arm plate. It is easy to install, has a reasonable and compact structure, and the clamping force meets the clamping requirements of large sponge blocks.

[0042] In this invention, during the clamping action of the clamping plate, the drive motors of the upper and lower lifting parts on both sides move synchronously to achieve synchronous lifting of the clamping plate. When the telescopic part extends, the drive motors of the upper and lower lifting parts on each side are independently controlled, driving the upper and lower lifting parts to move towards each other. In this way, the inner ends of the long arm plate and the short arm plate move towards the middle, and the outer end of the short arm plate rotates and supports relative to the middle position of the long arm plate, so that the front end of the long arm plate pushes the clamping plate forward. The two clamping plates move towards each other to clamp the sponge block. The clamping plate of this invention is also designed with a connecting rod. The length of the connecting rod is the same as the length of the long arm plate, and the installation distance between the two ends of the connecting rod and the end length of the long arm plate is also the same, thus forming a parallelogram. In this way, the clamping plate can always maintain a vertical clamping direction during the extension and retraction process, and the sponge block is clamped stably and reliably.

[0043] The stacking method of this invention adopts a special stacking method to stack sponge blocks of the same thickness or different thicknesses. The traditional stacking method uses a bottom-up stacking method, while this invention uses a top-down stacking method, which is an unconventional method to realize the stacking and removal of sponge blocks, which is convenient, reliable and meets the needs of sponge storage.
