Description

Technical Field

[0001] This utility model relates to the field of material transfer tool technology, and in particular to a transfer device for horizontally and vertically switching the placement of multi-layer co-extruded film rolls. Background Technology

[0002] In the production of multilayer co-extruded infusion films, the film rolls blown by the multilayer co-extrusion blown film equipment are approximately 1.2 meters wide. Depending on the pharmaceutical company's needs, they are cut into smaller rolls of different specifications during the slitting process. Before the slitting process, the produced full-width multilayer co-extruded film rolls need to be temporarily placed in the semi-finished product area, and only transferred to the slitting process when needed. To address the limited storage space in the semi-finished product area, the multilayer co-extruded film rolls need to be stored vertically.

[0003] Currently, the production efficiency of multi-layer co-extrusion blown film equipment is far greater than that of the slitting process. Large film rolls can only be stored in cleanrooms, and the storage space in the semi-finished product area is limited. As the production cycle of the multi-layer co-extrusion blown film process becomes longer, the storage pressure in the semi-finished product area is increasing. Multi-layer co-extrusion film rolls are rolled horizontally on the blown film equipment, but in order to save storage space for semi-finished products, the film rolls must be placed vertically. The weight of a multi-layer co-extrusion film roll is about 210kg, and it is very difficult to stand it upright by hand. Utility Model Content

[0004] The purpose of this invention is to provide a transfer device for switching between horizontal and vertical placement of multi-layer co-extruded film rolls. This device can not only transfer multi-layer co-extruded film rolls, but also effortlessly adjust multi-layer co-extruded film rolls from horizontal to vertical placement.

[0005] To achieve the above objectives, this utility model provides a transfer device for horizontally and vertically switching the placement of multilayer co-extruded film rolls, comprising two frames connected as a whole by multiple connecting rods. Each frame includes an upper horizontal bar, a lower inclined bar, an arc-shaped bar, and a longitudinal bar. One end of the upper horizontal bar is connected to one end of the lower inclined bar via the arc-shaped bar, and the other end of the upper horizontal bar is connected to the other end of the lower inclined bar via the longitudinal bar. Casters are installed at the lower end of the longitudinal bar. Wheel assemblies are installed at the ends of the lower inclined bars on both sides near the arc-shaped bar. An upwardly extending stop bar is installed at the end of the upper horizontal bar located on the arc-shaped bar, and a handle is formed at the end of the upper horizontal bar located on the longitudinal bar. A placement area is formed between the two upper horizontal bars.

[0006] At least one support rod is also fixedly connected between the upper horizontal bar and the lower diagonal bar.

[0007] The casters are swivel casters.

[0008] The upper crossbar is also fixedly connected to a push rod at the location of the longitudinal bar.

[0009] The wheel assembly includes an axle, a wheel, and a mounting base. The two mounting bases are respectively fixed to the lower side of the two lower inclined rods. The axle is mounted on the two mounting bases, and the wheels are mounted on both ends of the axle through bearings.

[0010] It also includes a placement seat, which includes a ring and a sleeve. The ring is located between two sleeves, and the sleeves on both sides are fixed to the ring by fixing rods. The sleeves are used to fit onto the stop rod.

[0011] The stop bar is provided with a first limiting hole, and the sleeve is provided with a second limiting hole. The pin can be detachably and obliquely inserted into the second limiting hole and the first limiting hole to limit the placement seat on the stop bar.

[0012] A placement plate is also installed on the upper side of the two upper crossbars. A recessed placement groove is provided in the middle of the placement plate, and the placement groove is arranged along the axial direction of the upper crossbar.

[0013] The upper crossbar is connected to the placement plate via a sliding structure, so that the placement plate can slide guided on the upper crossbar.

[0014] The sliding structure includes a linear guide rail and a slider. The linear guide rail is fixedly installed on the upper side of the upper crossbar. At least two sliders are installed on the lower side of the placement plate at positions corresponding to the two linear guide rails, and the sliders are slidably installed on the linear guide rails.

[0015] Compared with the prior art, this utility model has the following technical effects:

[0016] 1. This utility model features casters and wheel assemblies installed on the underside of the frame, forming a placement area between two upper crossbars. This allows for the placement of multi-layer co-extruded film rolls, which are then transferred using the casters and wheel assemblies. When the multi-layer co-extruded film roll needs to be adjusted from a horizontal to an vertical position, the frame can be easily flipped using the upward-lifting handle and the curved rod, thus adjusting the roll to an upright position. During the flipping process, a stop bar prevents the multi-layer co-extruded film roll from slipping off the frame. Because both ends of the central tube of the multi-layer co-extruded film roll extend a certain distance from the roll, and the central tube is supported on the ground while the roll is spaced from the ground, it will not press against the stop bar, allowing the frame to be removed. This utility model not only facilitates the transfer of multi-layer co-extruded film rolls but also allows for effortless adjustment from a horizontal to an vertical position.

[0017] 2. In this invention, when the multi-layer co-extruded film roll is erected, the placement seat is fitted onto the stop bar, and the ring body is aligned with the central tube, allowing the central tube to pass through the ring body. In this way, when the multi-layer co-extruded film roll is erected, the placement seat is supported at the lower end of the multi-layer co-extruded film roll, thereby improving the stability of the multi-layer co-extruded film roll when erected.

[0018] 3. This utility model increases the base area of ​​the multilayer co-extruded film roll by setting a placement plate, preventing the multilayer co-extruded film roll from being scratched by the vehicle frame. Furthermore, a recessed placement groove is provided in the middle of the placement plate to prevent the multilayer co-extruded film roll from rolling off the placement plate during transport.

[0019] 4. The upper crossbar of this utility model is connected to the placement plate through a sliding structure so that the placement plate slides on the upper crossbar to prevent damage to the multi-layer co-extruded film roll when it slides. Attached Figure Description

[0037] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0038] Example 1:

[0039] See Figure 1 , 2 A transfer device for horizontal and vertical switching of multilayer co-extruded film rolls includes two frames 10 connected together by multiple connecting rods 16. Each frame 10 includes an upper horizontal bar 11, a lower inclined bar 12, an arc-shaped bar 13, and a longitudinal bar 14. One end of the upper horizontal bar 11 is connected to one end of the lower inclined bar 12 via the arc-shaped bar 13, and the other end of the upper horizontal bar 11 is connected to the other end of the lower inclined bar 12 via the longitudinal bar 14. Casters 20 are installed at the lower end of the longitudinal bar 14. Wheel assemblies 30 are installed at the ends of the lower inclined bars 12 near the arc-shaped bar 13. An upwardly extending stop bar 19 is installed at the end of the upper horizontal bar 11 located on the arc-shaped bar 13. The end of the upper horizontal bar 11 located on the longitudinal bar 14 extends outward to form a handle 15. A placement area is formed between the two upper horizontal bars 11.

[0040] By mounting casters 20 and wheel assemblies 30 on the underside of the frame 10, and forming a placement area between the two upper crossbars 11, the multilayer co-extruded film roll 70 is placed into the placement area, and the multilayer co-extruded film roll 70 is transferred via the casters 20 and wheel assemblies 30. Figure 5 As shown. When it is necessary to adjust the multilayer co-extruded film roll 70 from horizontal to vertical placement, lift handle 15, see... Figure 6 The frame 10 can be easily flipped via the arc-shaped rod 13, thereby adjusting the multi-layer co-extruded film roll 70 into an upright position, such as... Figure 7 As shown. During the flipping process, the stop bar 19 blocks the multilayer co-extruded film roll 70, preventing it from slipping off the frame 10. Since both ends of the central tube 71 of the multilayer co-extruded film roll 70 extend a certain distance from the roll, and the central tube 71 is supported on the ground, while the multilayer co-extruded film roll 70 has a gap with the ground, it will not press against the stop bar 19, allowing the frame 10 to be removed. Figure 8 As shown.

[0041] Through the above structure and method, this transfer device can not only transfer the multilayer co-extruded film roll 70, but also effortlessly adjust the multilayer co-extruded film roll 70 from horizontal to vertical placement.

[0042] The connections between the upper horizontal bar 11 and the arc-shaped bar 13, the arc-shaped bar 13 and the lower diagonal bar 12, the upper horizontal bar 11 and the longitudinal bar 14, and the longitudinal bar 14 and the lower diagonal bar 12 are all fixed by welding. The connection between the stop bar 19 and the upper horizontal bar 11 is also fixed by welding.

[0043] Further, see Figure 2 At least one support rod 17 is also fixed between the upper crossbar 11 and the lower diagonal bar 12 to improve the structural strength of the frame 10.

[0044] In this embodiment, the caster 20 is a swivel caster, which facilitates direction adjustment during transport. During installation, the mounting plate on top of the swivel caster can be welded to the lower end of the longitudinal rod 14. Alternatively, the mounting plate can be welded to the lower end of the longitudinal rod 14, and the swivel caster can be bolted to the underside of the mounting plate.

[0045] See Figure 1 , 2 To facilitate pushing the transfer device, a push rod 18 is fixedly connected to the upper crossbar 11 at the longitudinal bar 14. With the push rod 18 installed, the operator can push the transfer device while standing.

[0046] Specifically, see Figure 2 The wheel assembly 30 includes an axle 31, a wheel 32, and a mounting base 33. The two mounting bases 33 are respectively welded to the lower side of the two lower inclined bars 12. The axle 31 is welded to the two mounting bases 33, and the wheels 32 are respectively mounted on both ends of the axle 31 through bearings. The wheel assembly 30 can adopt the wheel assembly structure of a wheel wagon.

[0047] Example 2:

[0048] See Figure 5 Since both ends of the central tube 71 of the multilayer co-extruded film roll 70 extend a certain distance from the multilayer co-extruded film roll 70, the multilayer co-extruded film roll 70 is only supported by the central tube 71 after it is erected, which makes its stability slightly insufficient and poses a risk of tipping over.

[0049] Therefore, based on Example 1, see Figure 1 , 4 The transfer device also includes a placement seat 60, which includes a ring 61 and a sleeve 62. The ring 61 is located between two sleeves 62. The sleeves 62 on both sides are welded and fixed to the ring 61 by fixing rods 63. The sleeves 62 are used to be fitted onto the stop rod 19.

[0050] When erecting the multilayer co-extruded film roll 70, the placement seat 60 is fitted onto the stop bar 19, see [reference]. Figure 5 The ring 61 is aligned with the central tube 71, allowing the central tube 71 to pass through the ring 61. This ensures that when the multilayer co-extruded film roll 70 is erected, the support 60 rests on the lower end of the roll. (See [reference]). Figure 8 This improves the stability of the multilayer co-extruded film roll when it is erected.

[0051] Furthermore, the stop bar 19 is provided with a first limiting hole 191, and the sleeve 62 is provided with a second limiting hole 621. The pin 64 can be detachably and obliquely inserted into the second limiting hole 621 and the first limiting hole 191 to limit the placement seat 60 on the stop bar 19, so that the ring body 61 is aligned with the central tube 71.

[0052] Example 3:

[0053] Based on Example 1 or Example 2, see Figure 1 A placement plate 40 is also installed on the upper side of the two upper crossbars 11. A recessed placement groove 41 is provided in the middle of the placement plate 40, and the placement groove 41 is arranged along the axial direction of the upper crossbars 11. By setting the placement plate 40, the base area with the multilayer co-extruded film roll 70 is increased, preventing the multilayer co-extruded film roll 70 from rubbing against the frame 10. Furthermore, the recessed placement groove 41 in the middle of the placement plate 40 prevents the multilayer co-extruded film roll 70 from rolling off the placement plate 40 during transport.

[0054] Example 4:

[0055] See Figure 5 When it is necessary to adjust the multilayer co-extruded film roll 70 from horizontal to vertical placement, lift the handle 15, see [reference]. Figure 6 The frame 10 can be easily flipped via the arc-shaped rod 13, thereby adjusting the multi-layer co-extruded film roll 70 into an upright position, such as... Figure 7 As shown. During the flipping process, the multilayer co-extruded film roll 70 will slide towards the stop bar 19. During the sliding process, the placement plate 40 will rub against the multilayer co-extruded film roll 70, thereby causing damage to the multilayer co-extruded film roll 70.

[0056] Therefore, based on embodiment 3, the upper crossbar 11 is connected to the placement plate 40 through the sliding structure 50 so that the placement plate 40 slides on the upper crossbar 11 to prevent damage to the multilayer co-extruded film roll 70 when it slides.

[0057] In this embodiment, the sliding structure 50 includes linear guide rails 51 and sliders 52. The two linear guide rails 51 are respectively fixedly installed on the upper side of the upper crossbars 11 on both sides. Two or three sliders 52 are installed on the lower side of the placement plate 40 at positions corresponding to the two linear guide rails 51 respectively. The sliders 52 are slidably installed on the linear guide rails 51.

[0058] Specifically, the linear guide 51 is bolted to the upper side of the upper crossbar 11, or welded to the upper side of the upper crossbar 11. The slider 52 is bolted to the lower side of the placement plate 40. Both the linear guide 51 and the slider 52 utilize existing technology.

[0059] The method of use or principle of this utility model:

[0060] See Figure 5 The multilayer co-extruded film roll 70 is placed on the placement slot 41 of the placement plate 40, and the multilayer co-extruded film roll 70 is transferred to the corresponding warehouse by pushing the handle 15 and / or the push rod 18.

[0061] See Figure 6 When the multilayer co-extruded film roll 70 needs to be adjusted from horizontal to vertical placement, lift the handle 15. At this time, the caster 20 is suspended in the air, and the arc-shaped rod 13 touches the ground. Then, the multilayer co-extruded film roll 70 moves downward with the placement plate 40. Since the ring body 61 is aligned with the central tube 71, the central tube 7 passes through the ring body 61. At this time, the pin 64 can be pulled outward. The pin 64 can be a light shaft structure.

[0062] By further lifting the handle 15, the frame 10 can be easily flipped via the arc-shaped rod 13, thereby adjusting the multi-layer co-extruded film roll 70 into an upright position, such as... Figure 7 As shown.

[0063] During the flipping process, the placement seat 60 blocks the multilayer co-extruded film roll 70 through the stop bar 19 to prevent the multilayer co-extruded film roll 70 from slipping off the frame 10.

[0064] When the multilayer co-extruded film roll 70 is erected, the placement seat 60 supports the lower end of the multilayer co-extruded film roll 70, improving the stability of the multilayer co-extruded film roll 70 when erected. Then, the outward moving device transfer device removes the frame 10 from the placement seat 60, as... Figure 8 As shown.

[0065] When the film needs to be retrieved, insert the stop bar 19 into the sleeve 62 of the placement seat 60, pull down the handle 15, and use the lever principle to lift the multilayer co-extruded film roll 70, then slowly return the transfer device to its original position. Figure 5 The status is being transferred.
