Description

Technical Field

[0001] This utility model relates to the field of sponge production and processing, and specifically to a sponge foam turnover device. Background Technology

[0002] After foaming, the sponge is typically cut into equal-length foam pieces and left to cure in a well-ventilated area. Due to the properties of the sponge, it cannot be transported using lifting equipment before curing and is usually laid flat in a designated area of ​​the workshop, resulting in low workshop utilization and increased production costs. To provide sufficient space for storing the foam pieces, a sponge storage warehouse was designed. The foam pieces are transported to the warehouse via a left-right movable transfer mechanism. The warehouse is designed with several storage stations, each storing one long sponge block (foam piece).

[0003] To facilitate the removal of foam from the foam storage warehouse, a foam transfer channel is constructed within the warehouse. A foam transfer mechanism moves foam from the storage station to this channel. The output foam then undergoes processing, such as foam cutting, on an external, independent processing production line. However, the foam transfer mechanism moves left and right, occupying a large space. Furthermore, the area where the foam transfer mechanism moves cannot accommodate other foam processing equipment, causing interference. While there is ample space above the working area of ​​the foam transfer mechanism, it is difficult to install the foam processing production line above it, as there is no space available for its installation. Summary of the Invention

[0030] See attached document Figure 1-12 A sponge foam turnover device includes a transfer mechanism 10, a sponge storage tank 8, crossbeams 20, and vertical supports 30. The transfer mechanism 10 is movably mounted on one side of the sponge storage tank 8. Several crossbeams 20 are installed parallel to each other on the ground. The crossbeams 20 are supported on the ground by several vertical supports 30. The lower end of the transfer mechanism 10 is mounted above the corresponding crossbeams 20 by several rolling mechanisms 4. The distance between adjacent vertical supports 30 is greater than or equal to the width of the sponge foam conveyor line 40. The height between the crossbeams 20 and the ground is... The working height of the foam conveyor line 40 is greater than or equal to that of the foam storage warehouse 8. The foam storage warehouse 8 includes several storage stations 81, foam expansion channels 82, and outbound turnover channels 83. Each storage station 81 has a foam expansion channel 82 at its lower end, and an outbound turnover channel 83 is also designed at the lower end of each storage station 81. A foam conveyor line 40 is installed on any side of the foam storage warehouse 8. When the foam conveyor line 40 is installed on the same side as the transfer mechanism 10, it is located below several crossbeams 20. Working channels are formed between adjacent vertical supports, and the foam conveyor lines are installed within the corresponding working channels. The height design of the vertical supports and the distance design between adjacent vertical supports meet the work requirements and can be adjusted according to time needs.

[0031] In this invention, sponge foam is fed into a foaming channel designed on one side of the sponge storage warehouse. The sponge foam is then transported to a transfer mechanism, which places the sponge foam into the corresponding storage station according to instructions. The design of the crossbeams and vertical supports elevates the transfer mechanism to a certain height, allowing the space below it to be reused for a sponge foam conveyor line. The transfer mechanism then transports the sponge foam retrieved from the storage station to the outbound turnover channel, which in turn transports the sponge foam to the sponge foam conveyor line for further processing. The design of the foaming channel is not strictly necessary; it depends on the location of the foaming mechanism. If it is located on the same side as the transfer mechanism, a foaming channel is unnecessary, and the foam can be directly transported to the transfer mechanism. If the foaming mechanism is located on the other side of the sponge storage warehouse, transporting the foam to the transfer mechanism requires crossing the warehouse. To make efficient use of space, a foaming channel is designed on one side below the warehouse to connect the two sides, thus avoiding unnecessary interference. The outbound turnover channel can be designed at the two lower compartments of the sponge storage warehouse, and adjusted according to the actual location of the sponge conveyor line.

[0032] The transfer mechanism 10 includes a horizontal conveying platform 101, a swing conveying platform 102, and a horizontal track 103. The front end of the horizontal conveying platform 101 is rotatably connected to one end of the swing conveying platform 102. The front and rear ends of the horizontal conveying platform 101 are respectively mounted on the corresponding horizontal tracks 103 via roller mechanisms 4. The other end of the swing conveying platform 102 is mounted on a horizontal track 103 via a portal frame 5. A swing platform 21 extends a certain length from the portal frame 5 at its front end. The upper sides of the portal frame 5 are respectively connected by steel wire ropes 51 to the two sides of the horizontal conveying platform 101 near the swing conveying platform 102. A lifting mechanism 6 is installed on each side of the portal frame 5. The lifting mechanism 6 includes a lifting motor 61, a sprocket 62, a chain 63, and a counterweight 64. A sprocket 62 is rotatably mounted on the upper end of the portal frame 5 near both sides. A lifting motor 61 is installed on each side of the upper end of the portal frame 5, driving the corresponding sprocket 62. A chain 63 is wound around the outside of each sprocket 62. One end of each chain 63 is connected to the upper end of a counterweight 64, and the other end of each chain 63 is connected to a corresponding side of a section of the swing platform 21 of the swing conveyor platform 102. The lower ends of the portal frame 5 are mounted on horizontal rails 103 via roller mechanisms 4. The portal frame and swing conveyor platform have an ingenious structural design and a compact overall structure. Steel wire rope traction ensures the portal frame will not tilt forward. The front end of the swing conveyor platform swings stably up and down within the portal frame via the lifting mechanism, forming a stable and balanced structure to ensure stable lifting and lowering. The lifting motors on both sides operate synchronously.

[0033] The lifting mechanism can also be designed as a winch. Two winches are installed on opposite sides of the upper end of the portal frame. The winches control the winding and unwinding of the wire rope via a drive motor, controlling the position of the two sides of the swing platform connected to a certain length. The two winches operate synchronously.

[0034] The horizontal track 103 includes a double-row track 31 and a single-row track 32. The lower end of the horizontal conveying platform 101 is guided by a double-row track 31 near both sides, and the lower end of the gantry frame 5 is guided by a single-row track 32. This invention is not limited to single-row or double-row tracks; it can be switched between single and double rows to meet specific usage requirements.

[0035] The roller mechanism 4 includes a main roller 41, side wheels 42, and a driving motor 43. A cross brace 53 is installed at the lower end of the gantry frame 5. The two ends of the cross brace 53 are respectively connected to the lower ends of the two sides of the gantry frame 5. One main roller 41 is rotatably installed on each side of the lower end of the cross brace 53. One or two side wheels 42 are installed near the two sides of the lower end of the cross brace 53. The two side wheels 42 are located inside the adjacent main rollers 41. The rolling surface of the main roller 41 presses on the upper surface of the single-row track 32, and the rolling surfaces of the two side wheels 42 respectively press on the two side surfaces of the single-row track 32. The driving motor 43 is installed at one lower side of the cross brace 53 and the driving motor 43 is drivingly connected to the adjacent main roller 41. The roller mechanism under the gantry frame is a roller mechanism matching the single-row track. The main roller is used for supporting and rolling, and the side wheels are used to prevent the main roller from deviating from the track path during walking, which is a safety design.

[0036] One rectangular frame 11 is installed on each side of the lower end of the horizontal conveying platform 101. One main roller 41 is installed at each of the four corner positions of the lower end of the rectangular frame 11, and two side wheels 42 are installed near the inner sides of the main rollers 41. The two main rollers 41 on one side of the lower end of the rectangular frame 11 roll on one side track of the double-row track 31 and the side wheels 42 inside the two main rollers 41 roll on the side surface of this side track; the two main rollers 41 on the other side of the lower end of the rectangular frame 11 roll on the other side track of the double-row track 31 and the side wheels 42 inside the two main rollers 41 roll on the side surface of this side track; One driving motor 43 is installed on one side of the rectangular frame 11. The driving motor 43 is drivingly connected to the adjacent main roller 41 and the driving motor 43 is also drivingly connected to the other main roller 41 at the same end through a synchronizing shaft 44. The synchronizing shaft design enables the main rollers on the double-row track to be driven by one driving motor, saving space and reducing costs.

[0037] The vertical frames 52 on the two sides of the gantry frame 5 are designed as frames with a triangular cross-section, and the counterweight 64 is also designed as a triangular block. The counterweight 64 can move up and down inside the vertical frame.

[0038] When this transfer mechanism is in use, the foam is first conveyed to the horizontal conveyor platform, and then to the swing conveyor platform. The end of the swing conveyor platform can be lifted to the required height by the lifting mechanism. A section of the swing conveyor platform is aligned with a workstation in the foam storage warehouse 8. When left and right translation is required, the drive motors of the roller mechanism of the single-row track and the double-row track are driven synchronously to control the horizontal conveyor platform 101 and the swing conveyor platform 102 to translate along the double-row track and the single-row track, respectively. The horizontal conveyor platform moves smoothly and reliably along the double-row track. One end of the swing conveyor platform also moves smoothly along the single-row track through the portal frame. It also meets the stability requirement that the portal frame will not tip over when the swing conveyor platform is raised and lowered. The upper end of the portal frame is pulled by a steel wire rope, and the portal frame pulls the end position of the swing conveyor platform through the lifting mechanism to form a stable force triangle. In this way, when the swing conveyor platform is raised and lowered, the portal frame can still be stably supported on the single-row track and will not tip over. The structure is ingenious and reasonable, simplifying the original complex support structure and reducing costs.

[0039] The foam conveyor line 40 includes a swing bridge 402, and the outbound turnover channel 83 includes an upper conveyor platform 831 and a lower conveyor platform 832, with the upper conveyor platform 831 mounted on the lower conveyor platform 832. The input end of the swing bridge 402 is connected to either the upper conveyor platform 831 or the lower conveyor platform 832 of the outbound turnover channel 83. The swing bridge 402 includes a conveyor belt 421, a rotating bracket 422, a lifting cylinder 423, a support arm 424, a guide rail 425, and guide wheels 426. The rotating bracket 422 is configured as a rectangular frame, with the conveyor belt 421 installed in the middle of the rotating bracket 422. The rotating bracket 422 is hinged to the ground at both ends on the side closest to the conveyor line 403. A guide rail 425 is installed on the lower sides of the rotating bracket 422. A lifting cylinder 423 is installed below the guide rails 425, with its lower end hinged to the ground. A support arm 424 is installed on the side of the lifting cylinder 423 closest to the conveyor line 403, with its lower end hinged to the ground. The upper end of the lifting cylinder 423 is rotatably connected to the support arm 424 near its center. A guide wheel 426 is installed on the upper end of the support arm 424, rolling and pressing against the guide rail 425. The ends of the rotating bracket 422 are hinged to the ground on both sides via isosceles trapezoidal supports 428, which are fixed to the ground. The ends of the rotating bracket 422 are rotatably connected to the isosceles trapezoidal supports 428.

[0040] The guide rail 425 is designed as a V-shaped raised track, and the rolling surface of the guide wheel 426 has a V-shaped annular groove in the middle. The guide wheel 426 is engaged with the V-shaped raised track through the V-shaped annular groove. This design ensures that the guide wheel travels safely and stably on the guide rail.

[0041] The lower end of the support arm 424 is hinged to one end of a horizontal base plate 427, and the lower end of the lifting cylinder 423 is hinged to the other end of a horizontal base plate 427; the horizontal base plate 427 is fixed to the ground. The design of the horizontal base plate ensures quick and accurate installation of the support arm and the lifting cylinder.

[0042] The support arm 424 includes an upper support arm 4241 and a lower support arm 4242, which are connected at an obtuse angle. A guide wheel 426 is mounted on the upper end of the upper support arm 4241, and the lower end of the lower support arm 4242 is hinged to the ground. The connection between the upper and lower support arms 4241 and 4242 is rotatably connected to the upper end of the lifting cylinder 423. The length of the upper support arm 4241 is longer than the length of the lower support arm 4242. The length of the upper support arm 4241 is twice the length of the lower support arm 4242. This support arm design ensures that even a short-stroke lifting cylinder can lift to a relatively high height, meeting lifting requirements. The support arm design includes two sets, left and right, which can be connected by two transverse shafts to achieve synchronous lifting movements.

[0043] The lifting cylinder 423 is designed to be any one of a hydraulic cylinder, a pneumatic cylinder, or a linear electric cylinder.

[0044] The feeding end of the rotating bracket 422 has a certain safety gap with the discharging end of the upper conveyor platform 831 or the lower conveyor platform 22. The safety gap ensures that the swinging end of the rotating bracket will not interfere with the end of the outbound turnover channel 83. A first proximity switch 48 and a second proximity switch 49 are installed on one side of the guide wheel 426. The first proximity switch 48 and the second proximity switch 49 are installed on one side of the rotating bracket 422, and there is a certain distance between the first proximity switch 48 and the second proximity switch 49.

[0045] When this sponge conveyor line is in use, during the operation of the outbound turnover channel 83, one conveyor platform transports the sponge bubble 7 onto the conveyor belt of the swing bridge, while the other conveyor platform receives the sponge bubble 7 transported from the sponge warehouse for temporary storage. The conveyor belt transports the first sponge bubble 7 onto the conveyor line. Sensors on the conveyor line detect the entry of the sponge bubble 7, and simultaneously, the conveyor line transports the sponge bubble 7 to the guide table for alignment as it passes through. After being aligned by the guide table, the sponge bubble 7 is transported to the bubble-cutting machine 5, where it is cut to the required length. After cutting, it is sent to the next process for cutting and shaping operations. Once the sensor detects that the first sponge bubble has completely passed through... Then the swing bridge starts to move, and the lifting cylinder controls the rotation of the support arm by pushing up or pulling down. The upper end of the support arm moves along the guide rail through the guide wheel, causing the rotating bracket to be lifted or lowered. The feeding end of the rotating bracket moves from the discharge end of one conveyor platform to the discharge end of another conveyor platform. In this way, the other conveyor platform performs the same operation on the temporarily stored sponge bubbles. At this time, the empty conveyor platform can receive sponge bubbles transported from the sponge silo. In this way, the time for cutting a sponge bubble is used to take out one sponge bubble from the sponge silo and place it on the outbound turnover channel 83. Time is used reasonably and the time wasted due to the sponge silo being taken out to the outbound turnover channel 83 is avoided, thus improving work efficiency.
