Description

Technical Field

[0001] The present invention relates to the technical field of logistics equipment, and in particular to a short-distance transfer device for roll materials. Background Art

[0002] In industrial production, large-sized rolls of materials with large aspect ratios, such as plastic film and fiber film, are common. Once these rolls are rolled, they need to be transferred to the next production process or temporarily stored. However, due to the processing, the coils still retain a certain temperature. To ensure product quality is not affected by high temperatures, they often need to be promptly transferred to heat dissipation equipment for cooling.

[0003] More importantly, this type of coil has extremely high requirements for surface cleanliness. During the subsequent transportation and storage process, once it is contaminated by dust or deteriorates due to moisture, its quality will be significantly affected, and may even cause the product to be scrapped, causing huge losses to the company. Therefore, the use of closed transportation and storage equipment has become an important means to ensure the quality of coiled materials. However, traditional closed transportation and storage methods have many disadvantages in actual operation. The closed structure of the equipment makes the loading and unloading process of materials extremely cumbersome, requiring a lot of manpower and time costs. At the same time, the purchase, maintenance and operation costs of closed equipment are also relatively high, which undoubtedly increases the operating burden of the company. In view of this, the research and development of a coiled material transfer device that has multiple functions such as heat dissipation, dust prevention, and moisture prevention is of great practical significance.

DETAILED DESCRIPTION

[0018] Example The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 13As shown, the short-distance transfer equipment for roll materials of this embodiment includes a horizontally arranged support frame 10, a roller 16 arranged below the support frame 10, a plurality of bearing components mounted above the support frame 10, an air supply device 30 arranged on the support frame 10, and a cover body 40 covered on the support frame 10; the plurality of bearing components are all covered in the cover body 40, and one bearing component is used to carry one roll 50; the bearing component includes a horizontally arranged support plate 21, a first support block 22 with a hollow structure arranged in the middle of the upper side of the support plate 21, a plurality of exhaust pipes 23 arranged on both sides of the first support block 22 and connected to the interior of the first support block 22, a plurality of exhaust holes 24 opened on the upper side of the exhaust pipe 23, a pair of second support blocks 25 respectively arranged at both ends of the upper side of the support plate 21, and an air inlet 26 opened in the middle of the support plate 21; the upper sides of the first support block 22 and the second support block 25 are both arc-shaped, and the air inlet 26 is connected to the interior of the first support block 22; the air supply device 30 is connected to the air inlet 26. Specifically, when in use, for a coil 50 that is horizontally arranged and uses a support shaft to pass through the center of the coil 50, a forklift can be used to lift the support plate 21 so that the lower side of the coil 50 rests on the first support block 22 and the second support block 25, and then the support shaft is removed, and the support plate 21 and the coil 50 are transferred to the support frame 10 by a forklift, and the air supply device 30 is connected to the air inlet 26 on the support plate 21. After multiple bearing components (each bearing component supports a coil 50 with a large aspect ratio) are transferred to the support frame 10, the cover body 40 is used to cover all the coils 50 and the support plate 21, and then the air supply device 30 is started. The air supply device 30 sends gas into the air inlet 26, the inside of the first support block 22, and the exhaust pipe 23, and finally through the exhaust The air holes 24 eject gas, which continuously purges the surface of the coil 50 from bottom to top. The support frame 10 can then be towed by a power device (such as a tractor) and transferred to the next production workshop. After being transferred to the destination, the power device is separated from the support frame 10. The air supply device can now continue to supply air (the air flow rate can be reduced). This allows the coil 50 to be stored (for logistics transfer or before entering the next production process) while continuously supplying air. This not only reduces the temperature inside the coil 50 to ambient temperature, but also prevents the surface of the coil 50 from getting damp. Furthermore, since the interior of the cover 40 is always in a positive pressure state, dust can also be prevented from entering and adhering to the surface of the coil 50. This effectively ensures the quality of fiber materials that are sensitive to temperature and humidity and susceptible to moisture. Furthermore, only the air supply device 30 of the entire device requires a small amount of energy, and the remaining structures are reusable, resulting in low costs after long-term use. It should be noted that a pair of insertion holes can be provided on the support plate 21 so that the front fork of a forklift can be inserted into the insertion holes, and then the support plate 21 and the coiled material 50 thereon can be lifted up.

[0019] In this embodiment, the first support block 22 is internally provided with a filter 27. The air supply device 30 includes a hollow air guide plate 31 horizontally mounted on the support frame 10, a plurality of air guide holes 32 formed on the upper side of the air guide plate 31, an air guide pipe 33 communicating with the interior of the air guide plate 31, and an air compressor 34 connected to the air guide pipe 33. The air compressor 34 is mounted on the support frame 10, with each air inlet 26 corresponding to each air guide hole 32. Specifically, the air supply device 30 delivers air into the first support block 22 through the air guide holes 32. After being filtered by the filter 27 within the first support block 22, the air is discharged from the exhaust holes 24 on the upper side of the exhaust pipe 23. The air compressor 34 compresses the air and sends it into the air guide plate 31 through the air guide pipe 33. When the support plate 21 is placed on the support frame 10, the lower side of the support plate 21 abuts against the upper side of the air guide plate 31, and the air inlet hole 26 on the lower side of the support plate 21 coincides with (i.e., is connected to) the air guide hole 32 on the air guide plate 31. At this time, the gas inside the air guide plate 31 can enter the first support block 22 through the air guide hole 32 and the air inlet hole 26.

[0020] In this embodiment, a plurality of top blocks 29 are provided on the lower side of the support plate 21, and the plurality of top blocks 29 are all arranged near the side wall of the air inlet hole 26. A baffle 35 is provided on the lower side of the air guide hole 32, and a spring 36 is provided on the lower side of the baffle 35. The lower end of the spring 36 abuts against the lower side of the inner wall of the air guide plate 31. The diameter of the baffle 35 is larger than the diameter of the air guide hole 32. When the upper side wall of the air guide plate 31 is attached to the lower side wall of the support plate 21, the lower end of the top block 29 abuts against the upper side of the baffle 35, and a gap is formed between the upper side of the baffle 35 and the inner top wall of the air guide plate 31. Specifically, by providing the structure of the top space, baffle 35, and spring 36, the gas in the air guide plate 31 will enter the first support block 22 through the air guide hole 32 and the air inlet hole 26 only when the support plate 21 is pressed against the air guide plate 31. The principle is that when there is no support plate 21 on the air guide plate 31, the baffle 35 is blocked at the air guide hole 32 by the action of the spring 36, and the gas in the air guide plate 31 cannot be discharged through the air guide hole 32. When the support plate 21 is pressed against the air guide plate 31, the top block 29 on the lower side of the support plate 21 pushes the baffle 35 downward, so that the air guide hole 32 can be exposed and connected to the air inlet 26. At this time, the gas in the air guide plate 31 can enter the first support block 22 through the air guide hole 32 and the air inlet 26. The advantage of this is that even when the support frame 10 is not fully loaded with support plates 21 and coils 50, the air supply device 30 can still be started normally.

[0021] In this embodiment, an annular sealing ring 210 is provided on the underside of the support plate 21; the air inlet 26 is provided in the sealing ring 210, which abuts the upper side of the air guide plate 31. Specifically, the sealing ring 210 has a certain thickness, so that even if the gap between the support plate 21 and the air guide plate 31 is within a certain range, the air guide hole 32 and the air inlet 26 can be properly connected.

[0022] The support frame 10 in this embodiment includes a pair of horizontally and parallelly arranged support plates 11, a connecting plate 12 for connecting one end of the pair of support plates 11, a towing hook 13 provided on the connecting plate 12, and a plurality of slots 14 provided on the upper side of the support plates 11, the plurality of slots 14 being distributed along the length of the support plates 11; an air guide plate 31 provided between the pair of support plates 11 and parallel to the support plates 11; and two ends of the support plate 21 being respectively secured in the slots 14. Specifically, rollers 16 are mounted on the lower side of the support plates 11, allowing the support frame 10 formed by the support plates 11 and the connecting plate 12 to move freely in a horizontal plane. The towing hook 13 allows the support frame 10 to be quickly connected and disconnected from the power equipment. The slots 14 provided on the support plates 11 and the two sides of the support plate 21 being secured in the slots 14 can prevent the support plate 21 from slipping on the support plates 11 during transfer.

[0023] In this embodiment, the upper side of the support plate 11 is provided with a plurality of upwardly-facing spotlights 15; one spotlight 15 is provided near a slot 14; an indicator block 211 is provided at each end of the support plate 21, and the indicator block 211 has a vertically-set through hole, in which a light-transmitting film 212 is provided; when both ends of the support plate 21 are engaged in the slot 14, the light-transmitting film 212 is located directly above the spotlight 15. Specifically, when transferring the support plate 21 and the coil 50 to the support plate 11, manual transfer using a forklift or other equipment is required. Due to the large volume of the coil 50 with a large aspect ratio, manual inspection to determine whether it is in place is difficult. Therefore, the spotlights 15 are provided on the support plate 11. When both ends of the support plate 21 are located directly above the slot 14 on the support plate 11, the spotlights 15 fully illuminate the light-transmitting film 212, causing the light-transmitting film 212 to change shape. By observing the light-transmitting film 212, workers can determine whether the position is appropriate.

[0024] The cover body 40 in this embodiment includes a storage plate 41 vertically arranged on the upper side of a pair of bracket plates 11 close to one end of the connecting plate 12, a partition plate 42 vertically arranged on the upper edge of the bracket plate 11, a slide groove 43 horizontally arranged on the upper side of the partition plate 42, and a hook 44 arranged on the end of the support plate 21 away from the connecting plate 12; the storage plate 41 is a hollow structure with an open upper end, and the storage plate 41 and the pair of partition plates 42 are enclosed to form a U-shaped structure; the cover body 40 also includes a dustproof cloth 45 arranged in the storage plate 41, the lower end of the dustproof cloth 45 is fixedly connected to the bottom of the storage plate 41, and the end of the dustproof cloth 45 away from the storage plate 41 is provided with a connecting rod 46; the two sides of the dustproof cloth 45 can be slidably arranged in the slide groove 43, and the connecting rod 46 can be hung on a pair of hooks 44; when the connecting rod 46 is hung on a pair of hooks 44, the dustproof cloth 45 is an inverted U-shaped structure (as shown in the attached figure). Figure 1As shown). Specifically, the dustproof cloth 45 itself is a non-sealed structure, and gas can pass through the dustproof cloth 45 and overflow outward, and when the dustproof cloth 45 is covered on the roll material 50, since the air supply device 30 continuously outputs air, the inside of the dustproof cloth 45 is always in a positive pressure state (the air flow will overflow in all directions such as up, down, left, right, front and back), and the air flow will push the dustproof cloth 45 upward to make the dustproof cloth 45 slightly arched, so that the dustproof cloth 45 will not contact the roll material 50, and the dustproof cloth 45 itself is a fiber material, which has a certain moisture absorption effect, so it can dehumidify the roll material 50 well and prevent the roll material 50 from getting damp. When there is no roll material 50 on the support frame 10, the dustproof cloth 45 is all located in the storage plate 41 (as shown in the attached figure). Figure 5 As shown, or the connecting plate 12 is at one end of the partition 42 close to the storage plate 41), when the coil 50 is fully placed on the bracket plate 11 (as shown in the attached Figure 3-4 As shown), by pulling the connecting rod 46, the dustproof cloth 45 can be pulled to fully cover the coil 50, and then the connecting rod 46 can be hung on a pair of hooks 44 to fix it. At this time, the coil 50 can be dustproofed by the dustproof cloth 45, the storage board 41 and the pair of partitions 42.

[0025] In this embodiment, a plurality of sliders 47 are provided on both sides of the middle portion of the dustproof sheet 45. The sliders 47 are slidably disposed in the chute 43. Specifically, by engaging the sliders 47 in the chute 43 so that they can slide in the chute 43 but not fall out of the chute 43 (e.g., a T-shaped chute 43 and sliders 47), both sides of the dustproof sheet 45 can be stably engaged in the chute 43.

[0026] In this embodiment, a driving device 37 is also included to drive the air guide plate 31 to rise and fall; a section of the air guide plate 31 close to the connecting rod 46 is a solid structure, and a pair of horizontally arranged limit plates 38 are provided at one end of the air guide plate 31 close to the connecting plate 12, and a vertically arranged limit rod 39 is provided on the lower side of the limit plate 38, and a limit sheet 310 is provided at the lower end of the limit rod 39, and a pair of limit holes are opened at one end of the air guide plate 31 close to the connecting plate 12; the length direction of the limit plate 38 is perpendicular to the length direction of the air guide plate 31, and the pair of limit plates 38 are distributed along the length direction of the air guide plate 31, and the two ends of the limit plate 38 are respectively fixedly connected to a pair of bracket plates 11, and a limit rod 39 is slidably set in a limit hole. Specifically, the reason for designing a drive device 37 to drive the air guide plate 31 to rise and fall is that: since multiple coils 50 need to be placed on the support frame 10, the length of the support plate 11 is relatively long. Therefore, when using a forklift to deliver the coils 50 and the support plate 21 to the support frame 10, the forklift may need to enter between the pair of support plates 11. At this time, considering that the air guide plate 31 may conflict with the forklift, the drive device 37 is used to move the air guide plate 31 down to the lowest position, at which time the forklift can normally enter between the support plates 11. And after all the coils 50 and the support plate 21 are installed on the support plate 11, the drive device 37 is used to drive the air guide plate 31 up so that the upper side of the air guide plate 31 abuts against the lower side of the support plate 21, thereby connecting the air path. The structure of the limit plate 38, the limit rod 39, and the limit hole can keep the air guide plate 31 in a horizontal state, so that it can be fully connected with the multiple support plates 21.

[0027] The drive device 37 in this embodiment includes a vertically mounted electric telescopic cylinder 371 and a mounting plate 372 for connecting the cylinder body of the electric telescopic cylinder 371 to the stop plate 38. The movable end of the electric telescopic cylinder 371 is fixedly connected to the air guide plate 31. Specifically, the electric telescopic cylinder 371 can be used to drive the air guide plate 31 in the vertical direction. Other drive mechanisms, such as an air cylinder, a hydraulic cylinder (a jack), or even manual operation, can also be used.

[0028] In summary, the short-distance transfer equipment for roll materials of this embodiment, when in use, for a roll 50 that is horizontally arranged and uses a support shaft to pass through the center of the roll 50, a forklift can be used to lift the support plate 21 so that the lower side of the roll 50 rests on the first support block 22 and the second support block 25, and then the support shaft is removed, and the support plate 21 and the roll 50 are transferred to the support frame 10 by a forklift, and the air supply device 30 is connected to the air inlet 26 on the support plate 21. After multiple bearing components (each bearing component supports a roll 50 with a large aspect ratio) are transferred to the support frame 10, the cover body 40 is used to cover all the rolls 50 and the support plate 21, and then the air supply device 30 is started. The air supply device 30 sends gas into the air inlet 26, the inside of the first support block 22, and the exhaust pipe. 23, and finally ejected through the exhaust hole 24, the ejected gas continuously purges the surface of the coil 50 from bottom to top. Then, the support frame 10 can be towed by a power device (such as a tractor) and transferred to the next production workshop. After being transferred to the destination, the power device and the support frame 10 are separated. At this time, the air supply device can continue to supply air (the air flow rate can be reduced). In this way, during the storage period of the coil 50 (for logistics transfer or before entering the next production process), the continuous air supply not only reduces the temperature inside the coil 50 to the ambient temperature, but also prevents the surface of the coil 50 from getting damp. Moreover, because the interior of the cover body 40 is always in a positive pressure state, it can also prevent dust from entering and adhering to the surface of the coil 50. For fiber materials that are sensitive to temperature and humidity and easily affected by moisture, their quality can be effectively guaranteed. In addition, only the air supply device 30 of the entire device requires a small amount of energy, and the remaining structures are all reusable, with low costs after long-term use.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
