Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitary material production and manufacturing technology, specifically to a roll material handling device. Background Technology
[0002] In the production of sanitary materials, raw materials such as non-woven fabrics and multi-layer composite materials need to be wound up using a horizontally cantilevered winding shaft to form rolls. After winding, the roll needs to be removed from the winding shaft to complete the unwinding process.
[0003] In addition, the unwound roll material needs to be packaged, and the conventional packaging method requires flipping the roll material from a parallel axis state during winding to a vertical axis state.
[0004] Currently, the aforementioned unwinding and flipping operations are mostly performed manually. To minimize roll changes and reduce downtime for roll replacements, downstream companies often require upstream companies to increase the length of the wound material during production. However, increasing the length of the wound material inevitably leads to a larger diameter or wider width. This increases the difficulty of unwinding, requiring multiple workers to assist in handling, which poses significant safety hazards. Furthermore, during manual unwinding and flipping, workers repeatedly come into contact with the roll material, creating a risk of contamination and rendering the roll material non-compliant with hygiene standards.
[0005] Therefore, there is an urgent need for a device that can assist workers in unwinding and flipping rolls of material. Utility Model Content

[0041] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.
[0043] In one embodiment, this application proposes a roll material handling device, such as... Figure 1-9 As shown, the roll material handling device includes a movable base, a pair of swing frames 301, and a retainer 302. The movable base can be moved by pushing and pulling. The pair of swing frames 301 are spaced apart and kept parallel. Since both ends of the pair of swing frames 301 need to be hinged, parallelism here means that the hinge axes of the pair of swing frames 301 are kept parallel.
[0044] Specifically, such as Figure 3-6 and Figure 8As shown, one end of the swing frame 301 is hinged to the movable base, and the other end of the swing frame 301 is hinged to the retainer 302. The hinge here means that the swing frame 301 can rotate relative to the movable base and the retainer about the hinge axis.
[0045] It should be noted that, taking a plane perpendicular to the rotation axes at both ends of the swing frame 301, the projections of the movable base, the pair of swing frames 301, and the retainer 302 onto this plane are approximately parallelograms. For example... Figure 6 and Figure 8 As shown, the movable base and the retainer 302 are generally parallel. When the pair of swing arms 301 swing relative to the movable base, the vertical position (i.e., height) of the retainer 302 changes. Furthermore, since the movable base, the pair of swing arms 301, and the retainer 302 are generally parallelograms, when the swing arms 301 swing relative to the movable base, not only will the vertical position of the retainer 302 change, but its horizontal position (i.e., lateral position) will also change.
[0046] To drive the swing frame 301 to swing, the roll material handling device proposed in this application also includes a drive mechanism, which is fixedly connected to the swing frame 301 located at the hypotenuse of one side of the parallelogram. Since workers will stand on the opposite side of the roll material during unwinding and handling, the drive mechanism is positioned on one side of the handling device for easy operation by the worker standing on that side. The drive mechanism adjusts the vertical and horizontal positions of the retainer 302 by driving the swing frame 301 to swing relative to the movable base.
[0047] During the winding process, the inner cylinder axis of the roll material is usually horizontal. However, when packaging the roll material, it needs to be adjusted to a vertical inner cylinder axis, thus requiring the roll material to be flipped. In this embodiment, the roll material handling device also includes a flipping frame 401, which is hinged to a retainer 302 located on the opposite hypotenuse of the parallelogram. Figure 7 As shown, the flipping frame 401 can rotate relative to the retainer 302, so the roll material lying flat on the flipping frame 401 can be flipped to a vertical position.
[0048] Before unwinding the roll, the tilting frame 401 is placed flat on the retainer 302. The base is pushed and pulled to position the tilting frame 401 and retainer 302 below the air-expanding take-up roller and aligned with the roll. At this time, the air-expanding take-up roller deflates, and the inner cylinder of the roll is attached to it. The swing frame 301 is driven to swing via a drive mechanism, causing the retainer 302 and tilting frame 401 to rise together. Figure 9-10 As shown, the roll material on the air-expanding take-up roller is lifted into a suspended state, and then the movable base is pulled, causing the roll material to leave the air-expanding take-up shaft. At this time, the roll material is placed on the flipping frame 401. When the roll material 501 is moved to the packaging station, as shown... Figure 11As shown, rotating the flipping frame 401 flips the roll 501, which was placed horizontally with the inner cylinder axis in a horizontal position, to a vertical position with the axis in a vertical position.
[0049] Regarding the structure of the movable base, in one optional implementation, such as Figure 1 As shown, the movable base includes a positioning frame 101 and a support frame 201. The support frame 201 is connected to the positioning frame 101 via a height adjustment mechanism. The height of the support frame 201 relative to the positioning frame 101 can be adjusted via the height adjustment mechanism. By adjusting the height of the support frame 201, the working height of the conveying device can be adjusted to adapt to the usage requirements under different working conditions.
[0050] like Figure 1-3 and Figure 6 As shown, the height adjustment mechanism includes multiple vertical rods 104 arranged symmetrically. In this embodiment, since the positioning frame 101 is roughly frame-shaped, there are four vertical rods 104, located at the four corners of the positioning frame 101. The vertical rods 104 are fixedly connected to the positioning frame 101, for example, by welding or bolting. Multiple vertically spaced first through holes 105 are provided on the vertical rods 104. The support frame 201 is provided with second through holes 202 corresponding to the first through holes 105. When adjusting the height of the support frame 201, the second through hole 202 is aligned with at least one first through hole 105, and bolts are inserted into the first through holes 105 and second through holes 202 to fix the support frame 201 to the positioning frame 101.
[0051] A pair of casters 103 are mounted on one side of the lower end of the positioning frame 101, and a pair of rollers 102 are mounted on the other side. The device can be steered using the casters 103. The casters 103 are located closer to the drive mechanism. Since the operator stands on this side, having the casters 103 positioned on this side makes it easier for the operator to steer the handling device.
[0052] It should be noted that the movable base and height adjustment mechanism are not limited to the above-described structure. Other structures in the prior art that can achieve the above functions are also applicable to this application, and will not be described in detail here.
[0053] For the drive mechanism, in one alternative implementation, such as Figure 4-9 As shown, the driving mechanism is a push-pull handle 304, one end of which is fixedly connected to the swing frame 301, for example, by welding. The connection point is located at the end of the swing frame 301 near the support frame 201, forming a structure similar to the lever principle. The angle between the push-pull handle 304 and the swing frame 301 is 45° to 115°, preferably 90°. When the operator holds the push-pull handle 304, they can control the swing frame 301 on one side to swing by pressing down or lifting the push-pull handle 304. At the same time, the swing frame 301 on the other side will also swing in response.
[0054] To improve structural strength, a reinforcing rib plate 305 is installed between the push-pull handle 304 and the swing frame 301. The reinforcing rib plate 305 is fixedly connected to the push-pull handle 304 and the swing frame 301 by welding or other methods.
[0055] After the roll 501 is unwound, during the movement of the handling device, the retainer 302 should be kept as stable as possible. When the retainer 302 is stable, the flipping frame 401 also remains stable. Optionally, a limiting mechanism 203 is installed at the upper end of the support frame 201. When the handling device moves, the limiting mechanism 203 is used to fix the retainer 302. The limiting mechanism 203 can be a limiting block, locking bolt, or other mechanism. The limiting mechanism 203 is used to prevent the retainer 302 from changing position during handling. The limiting mechanism 203 can also be other mechanisms in the prior art that can achieve the above functions, which will not be described in detail here.
[0056] Regarding the mounting structure of the swing frame 301, as an optional implementation scheme, such as... Figure 2-6 As shown, two pairs of first hinge mechanisms 204 are installed on the upper end of the support frame 201, and one end of the swing frame 301 is hinged to the support frame 201 through the first hinge mechanism 204. Two pairs of second hinge mechanisms 303 are installed on the lower end of the retainer 302, and the other end of the swing frame 301 is hinged to the retainer 302 through the second hinge mechanism 303. The first hinge mechanism 204 and the second hinge mechanism 303 can be bearings. It should be noted that other structures in the prior art that can realize the rotation of the swing frame 301 relative to the support frame 201 and the retainer 302 are also applicable to this application, and will not be described in detail here.
[0057] Regarding the mounting structure of cage 302, as an optional implementation, such as Figure 6 As shown, the cage 302 is equipped with a pair of third hinge mechanisms 402, and the tilting frame 401 is hinged to the cage 302 through the third hinge mechanisms 402. The third hinge mechanism can be a bearing. Other structures in the prior art that can realize the rotation of the tilting frame 401 relative to the cage 302 are also applicable to this application, and will not be described in detail here.
[0058] Optionally, a flip handle 404 is installed on the flipping frame 401. The flip handle 404 and the push-pull handle 304 are located on the same side. Since the operator stands on the side of the push-pull handle 304, placing the flip handle 404 on this side also makes it convenient for the same operator to flip the roll 501.
[0059] To improve the stability of the roll material placed on the flipping frame 401, a roll material support platform 403 can be installed on the upper surface of the flipping frame 401. The cross-section of the roll material support platform 403 is approximately "V" shaped. When the roll material 501 is placed on the roll material support platform 403, the platform on both sides of the "V" shape can restrict the roll material from rolling, thereby preventing the roll material from rolling to the ground during transportation.
[0060] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
