Description

Technical Field

[0001] The utility model relates to the field of sponge production and processing, in particular to a sponge lifting and stacking device. Background Art

[0002] Sponge is a porous elastic material. Commonly used sponges are made of foamed plastic polymers. They have a soft texture, dense internal pores, and a certain structural strength.

[0003] After foaming, the sponge is usually cut into the same size for storage, and then the sponge blocks are manually stacked together and sent to the warehouse for standby use. This method is labor-intensive and easily contaminates the sponge, and has been gradually eliminated.

[0004] At present, in modern factories of a certain scale, single sponge blocks are generally sent to multi-storey warehouses of equal height through main channel conveyors. Each floor has a spare auxiliary conveyor to facilitate the entry and exit of sponges, which makes the sponge storage cost high and the storage space difficult to be fully utilized.

[0024] Referring to the attached Figures 1-6 , a sponge lifting and stacking device, which includes a frame 1, a conveying platform 2, a lifting part 3, a clamping plate part 4 and a telescopic part 5. The conveying platform 2 is installed on the frame 1. Columns 6 are respectively arranged on both sides of the conveying platform 2, and the columns 6 are installed on both sides of the frame 1. One lifting part 3 can be installed in a liftable manner on the inner side of each column 6 on each side. The clamping plate part 4 is installed on the lifting part 3 through the telescopic part 5, and the clamping plate parts 4 on both sides perform opposite clamping actions.

[0025] The lifting part 3 includes a guide rail 31, a slider 32, a driving wheel 33, a tensioning wheel 34, a belt 35, a box body 36 and a driving motor 37. A driving wheel 33 and two tensioning wheels 34 are installed in the middle of the box body 36. The two tensioning wheels 34 are located on both sides of the driving wheel 33 near the bottom side. A driving motor 37 is installed outside the box body 36. The driving motor 37 is drivingly connected to the driving wheel 33. The guide rail 31 is installed inside the column 6. The slider 32 is installed at the bottom of the box body 36. The slider 32 is slidably installed on the guide rail 31. Both ends of the belt 35 are installed at the upper and lower ends inside the column 6 respectively, and the belt 35 is located outside the guide rail 31. The belt 35 passes through the upper and lower sides of the box body 36 and bypasses the outside of the driving wheel 33. The two tensioning wheels 34 press on the outside of the belt 35 from both sides; The telescopic part 5 is installed outside the box body 36. The belt can be designed as a synchronous toothed belt, and the driving wheel is designed as a synchronous pulley. The belt and driving wheel structure can also be designed as a chain and sprocket structure or a gear and rack structure; The driving motor is designed as a servo motor or a stepping motor.

[0026] On each side of the column 6, there are two lifting parts 3, namely an upper and a lower one, which are slidably installed. There are two columns 6 designed on each side. The driving 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, and share a driving motor 37 for driving; The driving 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, and also share a driving motor 37 for driving. This design is for large sponge blocks. The transverse length of the clamping plate part is relatively large. In order to meet the stability of the equipment, two columns are designed on each side for support. Correspondingly, an additional set of upper and lower lifting parts and telescopic parts are added on each side. The two groups support and control simultaneously from the back side of the clamping plate part, which is stable and reliable; And the two upper lifting parts and two lower lifting parts on each side are connected by a synchronous shaft to two driving wheels and driven by the same driving motor, which saves space and has a compact structure.

[0027] Or the lifting part includes a guide rail 31, a slider, a box body 36, a first telescopic oil cylinder 301 and a second telescopic oil cylinder 302. The guide rail 31 is installed inside the column. The slider is installed at the bottom of the box body 36. The slider is slidably installed on the guide rail 31. The first telescopic oil cylinder 301 is designed to be installed below the box body 36. The upper end of the first telescopic oil cylinder 301 is connected to the lower end of the box body 36, and the lower end of the first telescopic oil cylinder 301 is fixed on the frame; The lifting part is designed to have two sets, upper and lower, installed on the same column. The two sets of lifting parts are connected by a second telescopic oil cylinder 302. The upper end of the second telescopic oil cylinder 302 is connected to the lower end of the box body 36 of the upper lifting part, and the lower end of the second telescopic oil cylinder 302 is connected to the upper end of the box body 36 of the lower lifting part. The telescopic part is designed to be installed outside the two sets of upper and lower lifting parts; The upper end of the first telescopic oil cylinder is connected to the lower end of the box body of the lower lifting part.

[0028] 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 on the upper surface of the box body 36 of the lifting part 3, and the inner end of the short arm plate 52 is hinged on the upper surface of the box body 36 of the lower lifting part 3. The outer end of the short arm plate 52 is hinged at a position near the middle of the long arm plate 51. The middle of the inner end of the clamping plate part 4 is hinged at the outer end of the long arm plate 51. The upper end of the clamping plate part 4 is also connected to the upper surface of the box body 36 of the lifting part 3 by at least one connecting rod 41. One end of the connecting rod 41 is hinged on the upper surface of the box body 36 of the lifting part 3, and the other end of the connecting rod 41 is hinged on the upper end of the clamping plate part 4.

[0029] The distance between the two hinge points of the connecting rod 41 is the same as that of the long arm plate. The distance from the connecting rod 41 to the hinge point between the box body and the long arm plate 51 is the same as the distance from the hinge point of the connecting rod and the clamping plate part to the hinge point between the outer end of the long arm plate and the clamping plate part. The same length design forms a parallelogram shape that can rotate at four corners, so that the installation design of the clamping plate part will always maintain vertical clamping without tilting, and the clamping is stable and reliable.

[0030] The clamping plate part 4 includes an upper clamping plate 42 and a lower clamping plate 43 (the number of clamping plates is not uniquely limited and can be designed with multiple clamping plates according to needs). The upper clamping plate 42 and the lower clamping plate 43 are connected by a connecting brace 44. The middle of the connecting brace 44 is hinged at the outer end of the long arm plate 51. The upper end of the connecting brace 44 is fixedly connected to the back side of the upper clamping plate 42, and the lower end of the connecting brace 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 brace 44 of the clamping plate part 4.

[0031] A number of mounting holes 45 are designed on the working sides of the upper clamping plate 42 and the lower clamping plate 43, and sensors 46 are installed in the mounting holes 45. The design of the sensors ensures that the upper and lower clamping plates clamp the sponge block and transmit signals to the control unit, and the control unit controls the driving motor to continue rotating for a certain number of revolutions to accurately control the clamping depth and ensure the clamping force.

[0032] A number of protrusions 47 are respectively designed on the upper clamping plate 42 and the lower clamping plate 43. The design of the number of protrusions ensures that the clamping plates can effectively clamp the sponge block.

[0033] One end of the described conveying platform 2 is also designed with a turnover platform 8. The turnover platform 8 can be designed as a single conveying platform, or a platform for conveying translation trolleys, or a conveying platform for sponge processing equipment. The main design purpose is that when stacking or taking out sponge blocks 9, there are requirements for the stacking order or taking-out order of sponge blocks 9 with different thicknesses. At this time, the turnover platform 8 is used to temporarily turnover and place the sponge blocks 9 that do not need to be stacked or taken out. After the required sponge blocks are stacked or taken out, the sponge blocks 9 on the turnover platform 8 are then stacked. For example, if a sponge storage cabinet can store three sponge blocks with different thicknesses, when it is necessary to take out the middle or the top sponge block, the lower sponge block needs to be taken away. At this time, the device can hold the middle or the top sponge block, first convey the bottom or the bottom two sponge blocks to the turnover platform, and then place the required sponge block on the conveying platform and convey it out. The sponge blocks on the turnover platform can be operated accordingly according to subsequent needs to meet the requirements for sorting sponge blocks out of the warehouse.

[0034] When the present utility model is in use, the first sponge block is conveyed onto the conveying platform of the device. The device controls the telescopic part and the clamping plate part to lift and lower through the lifting part. When it descends to the positions on both sides of the sponge block, the telescopic part controls the clamping plate part to clamp from both sides of the sponge block. After the clamping is completed, the lifting parts on both sides rise synchronously to lift the first sponge block. At this time, the second sponge block is conveyed onto the conveying platform. The device controls the first sponge block to be stacked on the second sponge block. The device then repeats the above clamping action to clamp on the bottom sponge block, clamps and lifts it. After the third sponge block is conveyed onto the conveying platform, the above stacking action is repeated, and so on, until the set optimal stacking height is reached. Then the stacked sponge blocks are conveyed onto the designated storage shelf. When it is necessary to take out the stacked sponge blocks for machining and cutting shaping, the above stacking process can be reversed. The device can stack sponge blocks higher than the height of the device itself. In the case of small occupied space, it can still stack sponge groups with a relatively high height to meet the temporary storage requirements for sponge blocks in the warehouse.

[0035] The telescopic part in the device can adopt existing telescopic mechanisms such as telescopic cylinders. The clamping plate part adopts clamping plates. One end of the telescopic cylinder is installed outside the box body 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 according to needs. This kind of conventional structure of installing telescopic cylinders on the lifting part requires pulling air circuit components, etc., and one telescopic cylinder cannot meet the clamping requirements for larger sponge blocks, such as sponge blocks weighing more than 200 kilograms. The installation design is relatively cumbersome, and the present utility model will be simply described.

[0036] In the embodiment of the specific clamping action of the present utility model, for the telescopic action of the telescopic part, the telescopic actions of the upper and lower lifting parts on the same column need to control the cross-extension and contraction actions of the long arm plate and the short arm plate which are connected to each other in the up-and-down direction. In this way, the clamping part installed at the outer end of the long arm plate performs the telescopic action; this structure does not require the assistance of other telescopic mechanisms. By relying only on the cooperation of the upper and lower two sets of lifting parts with the cross-action of the long arm plate and the short arm plate, it can be achieved. It is convenient to install, the structure is reasonable and compact, and the clamping force meets the clamping requirements of large sponge blocks.

[0037] When the clamping part of the present utility model performs the specific clamping action, the driving motors of the upper and lower lifting parts on both sides perform synchronous lifting and driving actions to realize the synchronous lifting action of the clamping part; when the telescopic part performs the extension action, the driving motors of the upper and lower lifting parts on each side are independently controlled to drive 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 closer to the middle, and the outer end of the short arm plate rotates and supports relative to the position closer to the middle of the long arm plate, so that the front end of the long arm plate drives the clamping part to push forward, and the clamping parts on both sides move towards each other to clamp the sponge block; The clamping part of the present utility model 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 distances of both ends of the connecting rod from the end lengths of the long arm plate are also the same. In this way, a parallelogram is formed, so that the clamping part can always maintain a vertical clamping direction during the telescopic process, and the sponge block can be clamped stably and reliably.

[0038] The stacking method of the present utility model adopts a special stacking method to realize the stacking of sponge blocks with the same thickness or sponge blocks with different thicknesses. The traditional stacking method is to stack them from bottom to top in sequence, while the present utility model is to stack them from top to bottom in sequence, which is an unconventional method to realize the stacking and taking out of sponge blocks, which is convenient and reliable and meets the needs of sponge warehousing.
