Description

Technical Field

[0001] This application relates to the technical field of roll film processing, and in particular to an automatic loading and unloading device for roll film. Background Technology

[0002] Roll film mainly refers to packaging materials that are made by winding packaging film along a reel into a cylindrical shape. It is widely used in agriculture, packaging, construction, electronics, medical and health care and many other fields.

[0003] In some fields, long, heavy-duty roll films are required. Because of their width and weight, heavy-duty roll films are difficult to handle. Therefore, they are typically stored on low-level shelving. Low-level shelving generally consists of two sets of opposing vertical bars, each with horizontal bars. The ends of the roll film are placed on these horizontal bars for storage.

[0004] Regarding the aforementioned technologies, the existing storage methods for roll film occupy a large amount of space and do not make sufficient use of vertical space. However, if the shelves are raised, there will be difficulties in handling the roll film. Utility Model Content

The second guide seat slides up and down in the first guide groove.

[0014] By adopting the above technical solution, the cooperation between the guide shaft and the second guide seat makes the lifting platform more stable and reliable during movement.

[0015] Optionally, a first guide rod is provided on the lifting platform, and a first guide block is provided on the sliding platform. The first guide rod slides through the first guide block. The sliding drive assembly is a cylinder, which is located on the lifting platform. The telescopic shaft of the cylinder is connected to the sliding platform, and the length direction of the telescopic shaft is parallel to the length direction of the first guide rod.

When the roll is below, it can first abut against the side wall of the guide wheel and fall into the mounting groove between the two guide wheels.

[0018] By adopting the above technical solution, the mounting base is designed with a mounting plate and guide wheels, which facilitates the quick positioning and installation of the reel.

[0019] Optionally, it also includes a linkage component that, when the sliding table slides toward the shelf, drives the mounting base to move relative to the sliding table toward the shelf.

[0020] By adopting the above technical solution and adding the linkage component, when the sliding table slides towards the shelf, it can drive the mounting base to move relative to the sliding table towards the shelf. This design improves the efficiency of loading and unloading.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] Example 1:

[0037] This application discloses an automatic loading and unloading device for roll film. (Refer to...) Figure 1 The automatic loading and unloading device is mainly used to transport heavy roll film 102 up and down to the shelf 101, so that the roll film 102 can be stored on the high-level shelf 101. Therefore, the entire automatic loading and unloading device is placed on the feeding side of the shelf 101. The automatic loading and unloading device includes a support frame 1, a lifting platform 2, a lifting drive assembly 3, a sliding table 4, a sliding drive assembly 5, and a mounting base 6. The support frame 1 is fixed to the ground and is respectively set on the left and right sides of the shelf 101. The lifting platform 2 is set between the two. The lifting drive assembly 3 can drive the lifting platform 2 to move up and down along the support frame 1 to transport the roll film 102 to different heights on the shelf 101 for storage. The sliding table 4 is set on the lifting platform 2 and can be set at the left and right ends of the lifting platform 2. The sliding drive assembly 5 can drive the sliding table 4 to slide towards or away from the shelf 101. The mounting base 6 is set on the sliding table 4, and the upper surface of the mounting base 6 is provided with a mounting groove for the end of the roll to be engaged.

[0038] In this embodiment, sliding platforms 4 are respectively set at the left and right ends of the lifting platform 2, and two mounting bases 6 are also set for the two sliding platforms 4. In use, the rolls at both ends of the film roll 102 are respectively inserted into the mounting slots on the two mounting bases 6; then, the lifting platform 2 is driven upwards to the height of the corresponding shelf 101 by the lifting drive assembly 3; then, the sliding platforms 4 and mounting bases 6 are slid closer to the shelf 101 by the sliding drive assembly 5. When the rolls move onto the shelf 101, the lifting platform 2 is moved downwards by the lifting drive assembly 3, causing the rolls to fall onto the shelf 101, thus completing the loading process. Unloading is simply a matter of reversing the operation.

[0039] Reference Figure 1 and Figure 2 In this embodiment, specifically, the support frame 1 includes a support base 11 fixed to the ground by bolts or other means, and support rods 12 welded to the support base 11. Two support rods 12 are spaced apart on each support base 11 along the width direction of the lifting platform 2. The lifting platform 2 includes a platform base plate 21 and side baffles. The platform base plate 21 is a rectangular metal plate, and the side baffles are fixed to both ends of the platform base plate 21 respectively. A loading space 7 for placing the roll film 102 is formed between the two side baffles.

[0040] Reference Figure 1 and Figure 3 Furthermore, the lifting platform 2 also includes a guide shaft 23 and a second guide seat 24. The guide shaft 23 is cylindrical and extends along the width direction of the lifting platform 2. The guide shaft 23 is located on the side of the side baffle away from the loading space 7. The guide shaft 23 can be connected to the side baffle by welding metal rods. The second guide seat 24 is fixed to both ends of the guide shaft 23. The two support rods 12 located on the same support base 11 are provided with first guide grooves 121 on the side wall of the two support rods 12 that are close to each other. The second guide seat 24 can slide up and down in the first guide grooves 121, so that the lifting platform 2 can slide stably along the support rods 12.

[0041] Reference Figure 2 and Figure 4In this embodiment, the lifting drive assembly 3 includes a hydraulic cylinder 31, a lifting block 32, and a lifting rope 33. The hydraulic cylinder 31 is fixed to the support base 11 by bolts or other means. Preferably, the hydraulic cylinder 31 is positioned between two support columns. The main body of the hydraulic cylinder 31 can also be fixed to the support columns by steel wire or other means to improve the stability of the hydraulic cylinder 31. The telescopic shaft of the hydraulic cylinder 31 is vertically upward, and the lifting block 32 is fixed to the end of the telescopic shaft. The lifting rope 33 is fixedly connected to the end of the lifting block 32 facing the loading space 7. The lifting rope 33 extends downward and is fixed to the side baffle of the lifting platform 2, thereby enabling the hydraulic cylinder 31 to drive the lifting platform 2 to move up and down. Preferably, multiple lifting ropes 33 can be spaced along the width direction of the lifting platform 2 on each lifting block to improve stability. The lifting rope 33 can be a steel wire rope or a high-strength rope such as a metal chain.

[0042] Reference Figure 1 and Figure 4 Furthermore, the lifting drive assembly 3 may also include a guide plate 34 and a first guide seat 35. The guide plate 34 is fixed to the side wall of the lifting block 32 away from the loading space 7 by welding or bolts. Along the width direction of the lifting platform 2, the first guide seats 35 are respectively provided on both sides of the guide plate 34, and the first guide seats 35 on both sides can move up and down in the first guide groove 121, thereby improving the stability of the lifting block 32 when it moves up and down.

[0043] The first guide seat 35 and the second guide seat 24 can be configured as rectangular blocks. In this embodiment, the first guide block 41 and the second guide block 46 are configured as cylinders, and their axes are parallel to the width direction of the lifting platform 2. Rubber rings can also be provided on the outer walls of the first guide seat 35 and the second guide seat 24 to form a buffer between them and the support column, thereby improving the stability of the entire equipment operation and reducing noise.

[0044] Reference Figure 1 and Figure 2 In this embodiment, the sliding table 4 is composed of several metal plates welded together. Specifically, the sliding table 4 includes a first plate 42 arranged horizontally, the length direction of the first plate 42 being parallel to the width direction of the lifting platform 2; the sliding table 4 also includes a second plate 43 fixedly welded to the upper surface of the first plate 42, the second plate 43 being vertically arranged on the first plate 42, and the length direction of the second plate 43 being parallel to the length direction of the first plate 42. A first guide rod 25 is fixedly fixed on the platform base plate 21 of the lifting platform 2, and a first guide block 41 is fixedly welded to the lower surface of the first plate 42. Multiple first guide blocks 41 can be arranged at intervals along their length direction, and the first guide rod 25 can slide through the first guide block 41 to guide the sliding table 4.

[0045] The sliding drive assembly 5 is a cylinder 51, which is fixed to the platform base plate 21. The telescopic shaft of the cylinder 51 preferably extends towards the shelf 101. The end of the telescopic shaft can be connected to the sliding table 4 via a metal rod, thereby driving the sliding table 4 to slide towards or away from the shelf 101. The mounting base 6 can be fixed to the second plate 43. The mounting base 6 mainly consists of a mounting plate 61 and guide wheels 62. Specifically, the mounting plate 61 is a rectangular plate with mounting grooves on its upper surface. The guide wheels 62 are rotatably mounted at both ends of the mounting plate 61. The rotation axis of the guide wheels 62 is parallel to the length direction of the lifting platform 2. It should be noted that the height above the guide wheels 62 is higher than the height of the upper surface of the mounting base 6. When the film roll 102 is placed on the mounting base 6 in the feeding space 7, the roll can be manually lifted or lifted by equipment and inserted into the mounting groove from top to bottom. At this time, when there is a deviation between the position of the roll and the mounting groove, the side wall of the roll can first abut against the side wall of the guide wheel 62, and then the roll slides into the mounting groove along the guide wheel 62.

[0046] The implementation principle of an automatic loading and unloading device for roll film according to an embodiment of this application is as follows: When loading, the rolls at both ends of the roll film 102 are first inserted into the mounting slots on the two mounting seats 6 respectively; then the hydraulic cylinder 31 is activated to drive the lifting platform 2 to move upward to the height of the corresponding shelf 101; then the cylinder 51 is activated to drive the sliding table 4 and the mounting seat 6 to slide close to the shelf 101; when the roll moves to the shelf 101, the hydraulic cylinder 31 is used again to lift and move the lifting platform 2 downward, so that the roll falls onto the shelf 101, thereby completing the loading.

[0047] Example 2:

[0048] Reference Figure 1 and Figure 2 The difference between this embodiment and Embodiment 1 is that a linkage component 8 is added. When the sliding table 4 slides toward the shelf 101, the linkage component 8 can drive the mounting base 6 to move relative to the sliding table 4 toward the shelf 101, which further facilitates loading and also shortens the stroke of the cylinder 51 when loading.

[0049] Reference Figure 2 and Figure 3Specifically, the linkage assembly 8 includes a drive sprocket 81, a driven sprocket 82, a chain 83, a linkage shaft, a gear 84, and a linkage seat 85. The drive sprocket 81 and driven sprocket 82 are rotatably mounted on the side wall of the second plate 43, preferably on the side wall of the second plate 43 facing the loading space 7. The chain 83 passes around the drive sprocket 81 and driven sprocket 82. The mounting seat 6 is mounted on the upper surface of the chain 83. When the drive sprocket 81 rotates, the chain 83 rotates, causing the mounting seat 6 to move. The linkage shaft is rotatably mounted on the side wall of the second plate 43 via bearings or similar means. Both ends of the linkage shaft extend through the second plate 43. The end facing the loading space 7 is coaxially connected to the drive sprocket 81, and the end away from the loading space 7 is coaxially connected to the gear 84. Preferably, the drive sprocket 81 and gear 84 are located at the end of the second plate 43 furthest from the shelf 101.

[0050] The linkage seat 85 is welded and fixed to the platform base plate 21, and the linkage seat 85 is located on the side of the second plate 43 away from the loading space 7. The upper surface of the linkage seat 85 has a horizontal surface, and its upper surface is evenly provided with teeth along the width direction of the lifting platform 2. The gear 84 meshes with the teeth. When the sliding table 4 moves towards the shelf 101 under the drive of the cylinder 51, the gear 84 can rotate under the meshing with the teeth, thereby driving the drive sprocket 81 to rotate, and driving the chain 83 to rotate, thereby driving the mounting seat 6 located on the chain 83 to rotate.

[0051] Reference Figure 2 In this embodiment, a locking strip 431 is fixed to the side of the second plate 43 facing the feeding space 7. A locking groove is formed on the side of the locking strip 431 opposite to the second plate 43, allowing the upper part of the chain 83 to pass through the locking groove, thus providing support for the chain 83. A mounting block is fixed to the side of the chain 83 opposite to the second plate 43. Multiple mounting blocks can be spaced apart along the length of the chain 83, allowing the mounting base 6 to be fixed to the mounting blocks. Preferably, a tension sprocket 86 can also be provided on the second plate 43 to ensure stable rotation of the chain 83.

[0052] Reference Figure 2 In an optional embodiment, a horizontally arranged third plate 44 can be fixedly welded to the upper end of the second plate 43. A limiting seat 47 can be provided on the third plate 44. The limiting seat 47 is composed of three metal plates. The metal plate on the side away from the shelf 101 is a limiting baffle 471. A limiting wheel 472 can also be rotatably provided on the limiting baffle 471. When the sliding table 4 slides to the end away from the shelf 101, it is the loading and unloading position of the sliding table 4. At this time, after the roll is placed into the mounting groove, the side of the roll away from the shelf 101 can abut against the limiting wheel 472 or the limiting baffle 471, thereby preventing the roll film 102 from sliding away from the shelf 101.

[0053] Reference Figure 2 and Figure 3 In an optional embodiment, a vertical fourth plate 45 can also be welded onto the third plate 44. A second guide block 46 can also be welded onto the side wall of the fourth plate 45 facing the side baffle. A second guide rod 26 is fixed on the side baffle and slides through the second guide block 46, thereby further improving the stability of the equipment.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
