Description

Technical Field

[0001] The utility model relates to the technical field of film roll handling equipment, in particular to a film winding and lifting device. Background Art

[0002] In the automated production line of film production, the wound film rolls are often transported by lifting. Common automated lifting devices use gripper-type mechanical arms to take and place the film rolls, but the grippers need to apply a certain clamping force to ensure the stability of the clamping to avoid the film roll from falling during transportation. However, due to the thin thickness of the film itself, applying clamping force on the surface of the film roll can easily form clamping marks on the film surface, and even cause damage to the film, affecting the quality of the film roll. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a film winding and lifting device to solve the problem that the film roll is prone to clamping marks or damage due to clamping and lifting the film roll.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a film winding and lifting device, including a transverse movement mechanism, a lifting mechanism is movably arranged on the transverse movement mechanism, and a claw module is fixedly connected to the lifting end of the lifting mechanism; an arc limiting surface is arranged at the lower end of the claw module, and the arc limiting surface is respectively connected to a feed guide surface and a discharge limit surface on both sides of the transverse movement direction, a clamping block is popped out on the feed guide surface, and a gear rod is telescopically arranged on the discharge limit surface, and a clamping space adapted to the film roll is formed between the arc limiting surface, the clamping block and the gear rod.

[0005] Furthermore, the lever is arranged to be telescopically arranged vertically, and a downwardly opening clamping space is formed between the lever and the arc limiting surface. When the film roll is clamped into the clamping space, the clamping block abuts against the bottom cylindrical surface of the film roll.

[0006] Furthermore, a mounting groove is provided on the feed guide slide surface, the clamping block is swingably arranged in the mounting groove, one corner of the clamping block extends out of the feed guide slide surface, and the side of the clamping block away from its extended corner is in contact with the elastic sheet.

[0007] Furthermore, the clamping block is provided with a swing limiting groove, the swing limiting groove is slidably matched with a swing limiting column, and the swing limiting column is fixedly arranged on the inner wall of the installation groove.

[0008] Furthermore, the feed guide sliding surface is inclined toward a side away from the gear rod.

[0009] Furthermore, the discharging limit surface is arranged horizontally.

[0010] Beneficial effects: A film winding and lifting device of the present utility model uses a clamping jaw module of the snap-in type to pick up and place the film roll. During the process, the external force acting on the film roll is small. The binding force after clamping is light but the relative limit is firm. It not only ensures the stability during transportation, but also avoids the occurrence of clamping marks or clamping damage caused by applying excessive external force to the film roll during the picking-up, placing, and lifting processes, effectively ensuring the quality of the film roll after lifting.

[0013] The following further describes the present utility model with reference to the drawings.

[0014] As shown in the attached Figure 1-2 A film winding and lifting device as described above includes a transverse movement mechanism 1. A lifting mechanism 2 is movably arranged on the transverse movement mechanism 1. The lifting end of the lifting mechanism 2 is fixedly connected with a clamping jaw module 3. An arc-shaped limiting surface 31 is arranged at the lower end of the clamping jaw module 3. The arc-shaped limiting surface 31 is respectively connected with a feeding guiding sliding surface 32 and a discharging limiting surface 33 on both sides in the transverse movement direction. A clamping block 4 is elastically arranged on the feeding guiding sliding surface 32, and a blocking rod 5 is telescopically arranged on the discharging limiting surface 33. A clamping space adapted to the film roll is formed between the arc-shaped limiting surface 31, the clamping block 4, and the blocking rod 5.

[0015] In this solution, the transverse movement mechanism is used to make the clamping jaw module correspond to the film roll to be grabbed, and then the lifting mechanism is used to make the clamping jaw module approach and cooperate with the film roll. The film roll slides into the clamping space along the feeding guiding sliding surface. During the sliding process, the clamping block is pressed into the feeding guiding sliding surface, so that the film roll can enter the clamping space. When the film roll contacts the arc-shaped limiting surface and the blocking rod at the same time, the clamping block just pops out and abuts against the bottom cylindrical surface of the film roll, thus realizing the relative clamping and fixing of the film roll relative to the clamping jaw module. Subsequently, the lifting and transportation of the film roll can be completed through the cooperation of the transverse movement mechanism and the lifting mechanism. During the whole process, no excessive clamping force is applied to the surface of the film roll. After entering the clamping space, only the relative fixing relationship between the film roll and the clamping jaw module is maintained by the abutting and limiting of each part module. On the basis of ensuring the stability of the film roll during lifting, the occurrence of clamping marks on the film surface and clamping damage to the film is avoided.

[0016] The lever 5 is arranged to be telescopic vertically, and the lever 5 and the arc limit surface 31 form the clamping space with the opening downward. When the film roll is clamped into the clamping space, the clamping block 4 abuts against the bottom cylindrical surface of the film roll. When extracting the film roll through the clamping claw module, it is only necessary to drive the clamping claw module to align with the upper and lower positions of the film roll through the transverse movement mechanism, and then the lifting mechanism drives the clamping claw mechanism to vertically approach the film roll. As the clamping claw module moves downward, the film roll naturally abuts against the feed guide surface and gradually completes the above-mentioned clamping action. The structure is simple, the clamping is easy and quick, and the clamping is firmly fixed, which ensures the quality of the film roll after lifting and also ensures the efficiency of lifting.

[0017] The feed guide surface 32 is provided with a mounting groove, and the clamping block 4 is swingably arranged in the mounting groove, and one corner of the clamping block 4 extends out of the feed guide surface 32, and the side of the clamping block 4 away from its extended corner is in contact with the elastic sheet 6. The clamping block is roughly a triangular structure, and one corner is installed to rotate relative to the mounting groove through a rotating shaft; the corner extending from the feed guide surface, its upper side inclined surface is in contact with the cylindrical surface on the lower side of the film roll, to achieve a supporting and limiting effect, and its lower side inclined surface is used to fit and slide relatively with the film roll in the process of being inserted, so as to push the clamping block into the mounting groove, so that the film roll can pass over the clamping block and enter the clamping space, and complete the clamping and fixing of the film roll. When the clamping block is pushed to rotate in the mounting groove, the clamping block applies pressure on the elastic sheet, so that the elastic sheet is bent under force and stores elastic potential energy. After the film roll is inserted into place, the thrust on the clamping block disappears, and under the action of the elastic reset force of the elastic sheet, the clamping block is reset, and the extended corner part is high and buckled against the bottom side of the film roll. The clamping process is gentle with little resistance, and after clamping, it is stable without over-pressure or over-clamping.

[0018] The clamping block 4 is provided with a swing limiting groove 41, and the swing limiting groove 41 is slidably matched with a swing limiting column 42, and the swing limiting column 42 is fixedly arranged on the inner wall of the installation groove. The swing angle range of the clamping block can be constrained by the cooperation between the swing limiting groove and the swing limiting column. Under the thrust of the elastic sheet, when the clamping block is not subjected to other external forces, the swing limiting column always fits and limits with the end of the swing limiting groove away from the feed guide surface, so that the clamping effect of the clamping block is more stable, the clamping block will not swing at will, and will only shrink into the installation groove when the clamping block is pushed by external force from the bottom.

[0019] Preferably, a detection sensor 7 is provided at one end of the swing limit groove 41 close to the feed guide slide surface 32, which is used to sense the swing limit column, and the in-position signal output end of the detection sensor 7 is electrically connected to the control signal receiving end of the telescopic driving cylinder 8 of the gear lever 5. The feed guide slide surface 32 is tilted toward the side away from the gear lever 5. The discharge limit surface 33 is horizontally arranged.

[0020] After transporting the film roll to the target position, to ensure the integrity of the film roll and prevent it from unrolling, the clamping jaw module can be lowered so that the material table receiving the film roll contacts the clamping block and pushes the clamping block to retract, thereby making the film roll contact the material table. At the same time, due to the retraction of the clamping block, the swing limit post relatively moves to one end of the swing limit groove close to the inlet guiding sliding surface. After the detection sensor senses the swing limit post, a contraction control signal is sent to the telescopic driving cylinder 8, causing the blocking rod to contract upward and enter the inside of the outlet limiting surface, thereby creating a lateral opening in the clamping space. Subsequently, through the transverse movement mechanism moving in the opposite direction of this lateral opening, the clamping jaw module is separated from the film roll. During the separation process, the outlet limiting surface contacts the upper cylindrical surface of the film roll, and the clamping jaw module is lifted when leaving, ensuring that the film roll is stably located on the material table and preventing it from unrolling. This further ensures the quality of the thin film roll after hoisting.

[0021] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as within the protection scope of the present utility model.
