Description

TECHNICAL FIELD

[0001] The utility model relates to equipment loading and unloading technical field, specifically, it relates to a kind of loading and unloading tool of roll material. BACKGROUND

[0002] In the field of industrial production and material storage, roll material with central shaft cylinder, such as paper roll, stainless steel roll, etc., is a common storage and use object. Due to its large volume and heavy weight, special handling and supporting equipment is required during storage and use. Traditionally, for the storage of such roll material, a support is usually provided on each side. During handling, large auxiliary tools such as a crane or a forklift are used to hoist the roll material onto the supports.

[0003] However, this loading and unloading method is inefficient because the positions of the two supports need to be adjusted constantly during the loading and unloading of the roll material. In addition, due to the large volume and heavy weight of the roll material, personnel are needed to support the roll during hoisting to prevent the material from shaking or tilting during hoisting. This not only increases the safety risk of the operators, but also further increases the safety hazard when the operators are close to the roll material while adjusting the positions of the supports.

[0004] Furthermore, the traditional storage method requires multiple people to operate simultaneously, including hoisting personnel, roll supporting personnel, and support position adjusting personnel. This not only wastes a large amount of human resources, but also easily leads to communication problems and operational errors during multi-person cooperation, further reducing work efficiency.

[0036] This utility model provides a loading and unloading fixture for rolled materials. By improving the structure of the loading and unloading fixture for rolled materials, the loading and unloading efficiency of rolled materials is improved, while the loading and unloading costs and safety risks are reduced.

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0039] Please refer to Figures 1 to 6 As shown, Figure 1 This is a schematic diagram of the loading and unloading fixture for roll materials according to this utility model; Figure 2 for Figure 1 Enlarged view of section A; Figure 3 for Figure 1 Enlarged view of section B; Figure 4 for Figure 1 A cross-sectional view along the CC direction; Figure 5 for Figure 1 Side view; Figure 6 This is a schematic diagram of the base of this utility model.

[0040] To achieve the above objectives, such as Figure 1 , Figure 3 and Figure 6 As shown, this utility model provides a loading and unloading fixture for rolled materials, including a movable base 15, with casters 1 at the lower part of the base 15. The base 15 is used to support other components of the loading and unloading fixture and can drive other components to move in various directions on the horizontal plane through the casters 1.

[0041] The base 15 has a U-shaped structure and includes a first base rod 151. Second base rods 152 are fixed to both ends of the first base rod 151. A vertical rod 6 is provided on the upper side of the first base rod 151, extending along the height direction. The vertical rod 6 can move up and down along the height direction. A support rod 13 extending horizontally is rotatably connected to the vertical rod 6. The support rod 13 is inserted into the central shaft of the rolled material to be loaded or unloaded, so that when the vertical rod 6 moves up and down, the rolled material can be moved along the height direction via the support rod 13.

[0042] In the above technical solution, the vertical rod 6 provided on the upper side of the first seat rod 151 can be directly provided on the first seat rod 151 or indirectly provided. In the example shown in the figure, a support block 2 is also provided on the first seat rod 151. The support block 2 is fixedly connected to the first seat rod 151 and presses against the upper surface of the first seat rod 151. The vertical rod 6 is provided on the upper surface of the support block 2, that is, on the side of the support block 2 away from the first seat rod 151. Similar or identical solutions are all within the protection scope of this patent.

[0043] A plurality of support plates 14 are circumferentially distributed around the support rod 13. The support plates 14 are capable of radially expanding or retracting along the support rod 13 and can be maintained in the set position. The second seat rod 152 extends in the same direction as the support rod 13.

[0044] During use, the loading and unloading fixture is positioned so that the roll of material to be loaded or unloaded faces the roll. Specifically, the extension directions of the second seat rod 152 and the support rod 13 are aligned with the axial direction of the roll. The height of the vertical rod 6 is adjusted so that the height of the support rod 13 matches the height of the roll of material to be loaded or unloaded. The base 15 is pushed, and with the help of the casters 1, the base 15 and its other components move until the support rod 13 and the support plate 14 are inserted into the central shaft of the roll of material to be loaded or unloaded. During insertion, the support plate 14 is retracted to facilitate insertion. After insertion into the central shaft, the support plate 14 is driven to expand radially outward to support the inner wall of the central shaft, thus connecting the roll of material to be loaded or unloaded to the support rod 13. Then, the base 15 is pushed to move the loading and unloading fixture to the set position. After the roll of material is used, the operation is reversed to unload the central shaft to the set position.

[0045] By adopting the technical solution of this application, a vertical rod 6 that can move in the vertical direction is combined with a base 15 that can move in all directions in the horizontal plane to replace the forklifts and cranes in the traditional loading and unloading methods, which reduces the loading and unloading cost. At the same time, the loading and unloading of rolled materials can be completed by operating the loading and unloading tooling, which improves the integration of the tooling and the loading and unloading efficiency. In addition, during the loading and unloading process, the operator does not need to support the rolled materials. The support rod 13 is extended outward and supported in the central shaft cylinder of the rolled materials, which improves the safety of loading and unloading.

[0046] The following example illustrates the specific structure of the part that enables the vertical rod 6 to move in the height direction.

[0047] In this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the loading and unloading fixture for rolled materials also includes a first driving structure, which is used to drive the vertical rod 6 to move up and down along the height direction.

[0048] In the example shown, the first driving structure includes a first driving member, a first lifting rod 3, and a second lifting rod 17. The top ends of both the first lifting rod 3 and the second lifting rod 17 are hinged to the bottom of the vertical rod 6. The bottom end of the second lifting rod 17 is hinged to the base 15, that is, the second lifting rod 17 is hinged to the support block 2 or to the first seat rod 151. The bottom end of the first lifting rod 3 is connected to the first driving member and moves linearly under the drive of the first driving member to move closer to or away from the second lifting rod 17.

[0049] Driven by the first driving component, the bottom end of the second lifting rod 17 can rotate around a rotation axis, the extension direction of which is perpendicular to the direction of linear movement of the first lifting rod 3. This improves space utilization and reduces the space occupied by loading and unloading fixtures.

[0050] The first driving component can be driven by a mechanical structure or by a motor or cylinder to drive the bottom end of the first lifting rod 3.

[0051] In a more specific embodiment, a slider 18 is hinged to the bottom end of the first lifting rod 3, and the base 15 has a straight groove 8, within which the slider 18 is fitted. The first driving member includes a first screw 19, which is located within the groove 8 and forms a threaded pair with the slider 18. By employing the mechanical structure described in this embodiment to drive the first lifting rod 3, the cost of the loading and unloading fixture is further reduced, and the structural strength of the loading and unloading fixture is improved.

[0052] To facilitate manual operation, the first driving component further includes a first rocker arm 20 connected to the first screw 19. The first rocker arm 20 is located outside the slide groove 8 and on the outer side of the base 15, and is used to drive the first screw 19 to rotate. This facilitates manual operation of loading and unloading fixtures from the outside of the base 15, further ensuring the safety of the operator.

[0053] Specifically, in such Figure 6 In the example shown, the base 15 and the drum support device include the aforementioned support rod 13 and support plate 14. The base 15 is U-shaped, with a support block 2 above one end of the base 15 and a sliding groove 8 above the support block 2. The sliding groove 8 is located on the side where the first seat rod 151 is located, and the extension direction of the rotation axis is parallel to the second seat rod 152. Of course, if the first seat rod 151 is not provided with a support block 2, the sliding groove 8 can be directly provided on the first seat rod 151.

[0054] A screw 19 and a slider 18 are provided within the slide groove 8. The slider 18 is threadedly connected to the screw 19 and slidably connected to the slide groove 8. A first rocker arm 20 is provided at one end of the screw 19. A first lifting rod 3 is hinged above the slider 18, and a second lifting rod 17 is hinged to the other end of the support block 2. A vertical rod 6 is provided above the first and second lifting rods 3 and 17, respectively, and the first and second lifting rods 17 are hinged to the bottom of the vertical rod 6. The first lifting rod 3, the second lifting rod 17, and the slider 18 form a crank-slider 18 mechanism. A drum support device is provided on one side of the vertical rod 6, and one end of the drum support device is rotatably connected to the vertical rod 6 via a bearing. (The specific structure of the drum support device will be further explained later.)

[0055] By adopting the technical solution of this application, the height of the vertical rod 6 can be adjusted by driving the first lifting rod 3. The structure is simple and the operation is convenient.

[0056] The following is an example illustrating the specific structure of the support plate 14 relative to the support rod 13 in terms of radial expansion and retraction.

[0057] like Figures 1 to 5 As shown, the loading and unloading fixture for roll materials also includes a second driving structure. Under the drive of the second driving structure, the support plate 14 can move radially along the support rod 13 and remain in a set position.

[0058] The second driving structure includes a second driving member, a first connecting rod 24 and a third connecting rod 16 forming a two-bar linkage, and a guide rod 4 coaxially arranged with the support rod 13. A sliding cylinder 23 is sleeved on the outer side of the guide rod 4. The sliding cylinder 23 can slide along the extension direction of the guide rod 4 under the drive of the second driving member. The radial dimension of the guide rod 4 is smaller than that of the support rod 13. Thus, after the guide rod 4 is sleeved with the sliding cylinder 23, the sliding cylinder 23 can compensate for the difference in their radial dimensions, so that the outer wall of the sliding cylinder 23 and the outer wall of the support rod 13 are located on the same circumferential surface.

[0059] Furthermore, to ensure that the slide cylinder 23 does not rotate relative to the guide rod 4, while the guide rod 4 and the slide cylinder 23 form a circumferential anti-rotation fit, the slide cylinder 23 can also move linearly along the extension direction of the guide rod 4. Specifically, this can be achieved by using a keyway and key fit, a spline fit, or a spring snap fit, etc.

[0060] The first connecting rod 24 and the third connecting rod 16 have the same structure, both being two-bar linkages. The first connecting rod 24 and the third connecting rod 16 can be evenly distributed around the support rod 13 circumferentially, and their number can be set by those skilled in the art as needed. The middle portions of the first connecting rod 24 and the third connecting rod 16 are hinged to the inner side of the corresponding side of the support plate 14. One end of the first connecting rod 24 and the third connecting rod 16 on the same side is hinged to the slide cylinder 23, and the other end on the same side is hinged to the support rod 13. Here, "middle portion" refers to the midpoint along the length direction of the first connecting rod 24 and the second connecting rod 12.

[0061] This allows the support plate 14 to expand or retract radially, thus ensuring a tight fit against the inner wall of the roll of material. This prevents the roll from shifting position during loading and unloading, and also avoids the safety hazards associated with manually supporting the roll during loading, unloading, and use.

[0062] The second driving component can be driven mechanically or by means of a motor or cylinder. The following describes one possible specific structure of the second driving component using a mechanical structure as an example.

[0063] The second driving component also includes a driving block sleeved on the guide rod 4, the driving block forming a threaded pair with the guide rod 4; the driving block is disposed on the side of the slide cylinder 23 away from the support rod 13, the driving block and the slide cylinder 23 are axially limited and can rotate freely in the circumferential direction. Here, the manner in which the driving block and the slide cylinder 23 are axially limited and can rotate freely in the circumferential direction can be set by those skilled in the art according to the actual situation, and all technical solutions that can achieve the above functions are within the protection scope of this patent.

[0064] By employing the mechanical structure described in this embodiment to drive the support plate 14 to move, the cost of loading and unloading tools can be reduced, and their structural strength and durability can be improved.

[0065] Optionally, the system further includes a plurality of second connecting rods 12, which are distributed circumferentially around the support rod 13. One end of each second connecting rod 12 is hinged to the inner side of the support plate 14, and the other end is hinged to the support rod 13. This further enhances the radial support force of the support plate 14 and improves the fixing strength of the loading and unloading fixture for rolled materials.

[0066] To enable relative rotation between the guide rod 4 and the vertical rod 6, the vertical rod 6 has an insertion hole. The end of the guide rod 4 furthest from the support rod 13 is inserted into the insertion hole and can rotate relative to the insertion hole. Thus, personnel can rotate the rolled material by rotating the guide rod 4, avoiding the need for manual pulling of the rolled material in traditional solutions.

[0067] In the example shown in the figure, the drum support device includes a guide rod 4 and a nut 21. The nut 21 serves as the aforementioned drive block. The guide rod 4 is rotatably connected to the vertical rod 6 via a bearing. A second rocker arm 5 is provided at one end of the guide rod 4, and a support rod 13 is provided at the other end of the guide rod 4. The nut 21 is threadedly connected to the guide rod 4. A handle 22 is provided on the outside of the nut 21. A slide cylinder 23 is fitted on the guide rod 4. Several first connecting rods 24 are hinged to the outside of the slide cylinder 23. Second connecting rods 12 and third connecting rods 16 are hinged to the outside of both ends of the support rod 13 at positions corresponding to the first connecting rods 24. The first connecting rods 24, second connecting rods 12, and third connecting rods 16 are respectively hinged to the bottom of the support plate 14. The first connecting rods 24, second connecting rods 12, and third connecting rods 16, the slide cylinder 23, and the support plate 14 constitute a crank-slider 18 mechanism.

[0068] In other embodiments of this application, the loading and unloading fixture further includes a horizontal bar 7 parallel to the support rod 13. One end of the horizontal bar 7 is fixed to the vertical rod 6, and the other end is connected to a stop bar 10. The stop bar 10 can be connected to the support rod 13 to form a closed structure with the support rod 13, the horizontal bar 7, and part of the vertical rod 6. This further restricts the movement of rolled materials, preventing them from detaching from the loading and unloading fixture during loading, unloading, and use. Furthermore, the stop bar 10 can also hold the end of the rolled material away from the vertical rod 6, allowing the loading and unloading fixture to accommodate heavier rolled materials.

[0069] In a specific example, a horizontal bar 7 is provided on one side of the top of the vertical bar 6, and a sliding groove 8 is provided at the other end of the horizontal bar 7. A sliding rod 9 is provided in the sliding groove 8. A stop rod 10 is hinged to the sliding rod 9. The stop rod 10 can move under the action of the sliding rod 9. The stop rod 10 can be flipped to the top of the horizontal bar 7. When there is no material placed on the rack, the stop rod 10 can be flipped to the top of the horizontal bar 7. A sliding hole 11 is provided at the lower part of the stop rod 10 corresponding to the support rod 13. The support rod 13 and the sliding hole 11 can be rotatably connected.

[0070] The following describes the specific usage of the loading and unloading fixture. During operation, first crank the first rocker arm 20 to rotate the screw 19, thereby moving the slider 18. The slider 18 then moves the first lifting rod 3 and the second lifting rod 17. The vertical rod 6, hinged to the first and second lifting rods 3 and 17, moves up and down. The roll support device connected to the vertical rod 6 also moves up and down, moving the roll support device to the position of the central shaft of the material roll. Then, move the placement frame so that the roll support device is inserted into the central shaft of the material roll. Next, rotate the nut 21 via the handle 22, causing the nut 21 to push the slide cylinder 23 to move. The movement of the slide cylinder 23, through the first connecting rod 24, the second connecting rod 12, and the third connecting rod 16, causes the support plate 14 to move outward, pressing against the inner wall of the central shaft of the material roll. Then, flip the stop rod 10 to below the horizontal rod 7 and move the stop rod 10 so that one end of the support rod 13 is inserted into the sliding hole 11. Finally, crank the first rocker arm 20 to raise the material roll to the appropriate height. In addition, when using the material roll, before pulling the material, the second rocker arm 5 is shaken, which causes the guide rod 4 to rotate under the support of the vertical rod 6 and the stop rod 10, thereby driving the material roll to rotate, making it time-saving, labor-saving, safe, fast and efficient when pulling the material.

[0071] Compared with the prior art, this application has the following advantages:

[0072] First, by using the loading and unloading fixtures for roll materials in this application, loading and unloading roll materials is more labor-saving and easier to operate. A single person can complete the loading and unloading, saving time and effort and significantly improving work efficiency.

[0073] Secondly, the first rocker arm 20 drives the screw 19 to rotate, which in turn causes the slider 18 to move the first lifting rod 3 and the second lifting rod 17, thereby realizing the lifting and lowering of the roll support device, making the loading and unloading of roll materials more convenient. When the staff pulls the material outward, the second rocker arm 5 and the guide rod 4 can also rotate the roll material, so that the material automatically extends or rolls up, which solves the safety hazard that the support may tilt during the process of the staff pulling the material outward, protects the staff or the equipment, avoids the problem of the material not being able to be pulled, and also saves effort.

[0074] Third, the loading and unloading fixture for roll materials in this application has a simple structure, reasonable design, and convenient operation. It is applicable to various roll materials with different diameters and lengths of the central shaft cylinder, making it more convenient for workers to use.

[0075] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
