[0038] like Figures 1 to 5As shown, the present invention provides a film removal clamp suitable for removing the outer film of various tobacco auxiliary material piles, and completes the cutting operation of the film 100 and the collection operation of the cut film 100 through two major actions of film cutting and film clamping. The film removal clamp includes a base 1, a cutting mechanism 2 and a clamping mechanism 3. The cutting mechanism 2 includes a film hooking member 21 and a cutting member 22. The film hooking member 21 is connected to the base 1, and the film hooking member 21 can extend between the film 100 and the product 200 to make the film 100 cover the top surface of the film hooking member 21; the cutting member 22 is connected to the base 1, and is used to cut the film 100 covered on the film hooking member 21; the clamping mechanism 3 includes a driving member 31, a first clamping member 32 and a second clamping member 33. The driving member 31 is connected to the base 1, the first clamping member 32 is fixed to the base 1, and the second clamping member 33 is connected to the output end of the driving member 31. The driving member 31 is used to drive the second clamping member 33 to move so that the second clamping member 33 is close to or away from the first clamping member 32, so as to clamp or release the film 100. When cutting the film 100, the hook film member 21 extends between the film 100 and the product 200 to separate the film 100 and the product 200, and the cutting member 22 cuts the film 100 covered on the hook film member 21. By providing the hook film member 21, it is prevented that the tobacco auxiliary material, that is, the product 200, is cut by the cutting member 22. When removing the film 100, the film 100 is cut by the cutting member 22. After cutting, the driving member 31 drives the second clamping member 33 to move so that the second clamping member 33 is close to the first clamping member 32, and the film 100 is clamped, which is convenient for the subsequent peeling of the film 100 from the product 200. The cutting mechanism 2 and the clamping mechanism 3 of the present invention have simple and compact structures, occupy a small space, and have low cost. In addition, the cutting mechanism 2 and the clamping mechanism 3 are integrated to improve the degree of integration.
[0039] Optionally, the front end of the hook film member 21 is provided with a sharp corner 211. By providing the sharp corner 211, it is convenient for the hook film member 21 to hook the film 100 from the product 200, and the hook film member 21 is located between the film 100 and the product 200.
[0040] Optionally, the cutting mechanism 2 further includes a buffer assembly, which includes a fixed seat 231, a guide member 232 and an elastic member 233. The fixed seat 231 is fixed to the base 1, and the fixed seat 231 is provided with a guide hole. One end of the guide member 232 is fixed to the film hook member 21, and the other end of the guide member 232 passes through the guide hole and is slidably connected with the guide hole. The elastic member 233 is arranged between the film hook member 21 and the fixed seat 231. Specifically, the fixed seat 231 includes a seat body and a guide sleeve 2311, the guide sleeve 2311 passes through the seat body, and the guide hole is located in the guide sleeve 2311. By providing the buffer assembly, when the film hook member 21 approaches the product 200, the guide member 232 floats up and down in the fixed seat 231 to prevent the film hook member 21 from hitting the product 200, wherein the elastic member 233 provides floating power. In addition, the buffer component can also provide a certain degree of adaptation to upper and lower unevenness. When the film hook member 21 extends between the film 100 and the product 200, it ensures that the bottom of the film hook member 21 is always in contact with the product 200, which plays a role in smoothly hooking the film and enables the film hook member 21 to stably complete the film hooking and extension functions.
[0041] In the present embodiment, the elastic member 233 is a spring, which is sleeved on the guide member 232, and one end of the spring abuts against the hook film member 21, and the other end abuts against the fixed seat 231. Such a configuration makes the structure of the buffer assembly simple, easy to install, and space-saving, and the guide member 232 plays a guiding role in the compression of the spring. Of course, in other embodiments, the spring may not be sleeved on the guide member 232, and one end of the spring is fixedly connected to the hook film member 21, and the other end is fixedly connected to the fixed seat 231. In addition, in the present embodiment, in order to ensure the balance of force, two guide members 232 are spaced apart on the hook film member 21, and two guide holes are arranged one by one with the two guide members 232, and each guide member 232 is sleeved with a spring.
[0042] Optionally, the buffer assembly further includes an anti-collision sensor 234 and a trigger 235. The anti-collision sensor 234 is fixed to the base 1, and the anti-collision sensor 234 is configured to communicate with the moving mechanism. The trigger 235 is fixed to the guide member 232 and is used to trigger the anti-collision sensor 234. The moving mechanism is connected to the base 1 of the film removal clamp, and drives the film removal clamp to move so that the hook film member 21 contacts the product 200. In this process, due to the action of the elastic member 233, the guide member 232 will slide up and down along the guide hole, thereby causing the trigger 235 to move up and down. When the trigger 235 moves to trigger the anti-collision sensor 234, the moving mechanism stops moving the film removal clamp. By setting the trigger 235 and the anti-collision sensor 234, a safety protection function is played to avoid the collision of the hook film member 21 with the product 200. In this embodiment, the trigger 235 is an L-shaped plate, one end of the L-shaped plate is fixedly connected to the guide member 232, and the other end of the L-shaped plate is used to trigger the anti-collision sensor 234.
[0043] Optionally, in this embodiment, if Figure 3 and Figure 5 As shown, the cutting member 22 is a high-frequency vibration knife, and a knife avoidance groove 212 is provided on the top of the film hooking member 21. Specifically, the high-frequency vibration knife is fixed to the base 1 through the vibration knife fixing seat 221, and the high-frequency vibration knife cuts the film 100 through the blade 222, and a cutting space 24 is formed between the blade 222 and the film hooking member 21. The cutting member 22 is a high-frequency vibration knife, which not only improves the cutting accuracy, speed and quality of the film 100, but also greatly prolongs the service life of the knife, reduces the maintenance cost, and avoids frequent knife changes. By setting the knife avoidance groove 212, when the high-frequency vibration knife is vibrating, the blade 222 of the high-frequency vibration knife vibrates up and down at a high frequency, and the knife avoidance groove 212 can avoid the vibration space of the blade 222, so as to avoid the collision between the blade 222 and the film hooking member 21. In addition, when the high-frequency vibration knife cuts the film 100, it can pass through the film 100 and be located in the knife avoidance groove 212, so that the film 100 can be effectively cut, and the continuity and integrity of the cutting can be ensured. In addition, the high-frequency vibration knife in this embodiment is driven pneumatically, and the size of the airflow is adjusted by the airflow adjustment member 223.
[0044] Optionally, the first clamping member 32 includes a fixing portion 321 and a clamping portion 322, the fixing portion 321 is fixed to the base 1, and the clamping portion 322 is arranged obliquely relative to the base 1. With such an arrangement, when the moving mechanism moves the film removal clamp, the surface of the clamping portion 322 close to the second clamping member 33 first contacts the film 100, and the film 100 can be smoothly hooked up, making it convenient for the second clamping member 33 to approach the first clamping member 32 and clamp the film 100. In addition, the clamping mechanism 3 can be arranged at different spatial positions as needed. In this embodiment, the clamping mechanism 3 and the cutting mechanism 2 are arranged back to back, so that the cutting and clamping operations do not affect each other.
[0045] Optionally, in this embodiment, the second clamping member 33 is rotatably connected to the base 1, and the output end of the driving member 31 is connected to the second clamping member 33, which is used to drive the second clamping member 33 to swing. When the second clamping member 33 rotates to approach the first clamping member 32, the film 100 is clamped, and when the second clamping member 33 rotates to be away from the first clamping member 32, the film 100 is released. Such a configuration saves space and can achieve reliable clamping of the film 100. Further, the driving member 31 is a cylinder, which is rotatably connected to the base 1, and the push rod of the cylinder is rotatably connected to the second clamping member 33. Such a configuration can ensure smooth and flexible swinging of the second clamping member 33, and the cost is low. In addition, a solenoid valve island module 34 is installed on the base 1, and the solenoid valve island module 34 is used to control the on and off of the airflow in the cylinder. Of course, the driving member 31 can also be an electric push rod or a hydraulic cylinder.
[0046] In other embodiments, the output end of the driving member 31 is connected to the second clamping member 33 for driving the second clamping member 33 to translate so that the second clamping member 33 approaches or moves away from the first clamping member 32 .
[0047] Optionally, the clamping mechanism 3 further includes a detection sensor 35 for detecting the extended position of the push rod of the cylinder, and the detection sensor 35 is configured to be in communication connection with the moving mechanism. The detection sensor 35 detects the extended position of the push rod of the cylinder to detect whether the second clamping member 33 and the first clamping member 32 clamp the film 100. When the detection sensor 35 detects that the push rod reaches the specified extended position, that is, the second clamping member 33 can clamp the film 100 with the first clamping member 32, the detection sensor 35 transmits the information to the moving mechanism, and the moving mechanism starts to move the film removal clamp to pull the film 100, so that the film 100 is separated from the product 200, and the film 100 is collected.
[0048] Optionally, both the first clamping member 32 and the second clamping member 33 are provided with a soft rubber pad 37 for increasing the friction force, enlarging the effective area of the clamping film, and improving the stability of the clamping film.
[0049] Optionally, the clamping mechanism 3 further includes a film in-position sensor 36, which is fixed to the first clamping member 32 and is used to detect whether the film 100 between the first clamping member 32 and the second clamping member 33 falls off when the film removal clamp is in different positions and postures.
[0050] Alternatively, if Figure 5 As shown, the film removal fixture further includes a distance sensor 4, which is fixed to the base 1 and used to detect the distance between the base 1 and the product 200, and the distance sensor 4 is configured to communicate with the moving mechanism. When the moving mechanism carries the film removal fixture close to the product 200, the distance detection sensor 35 will detect the distance between the base 1 and the product 200, and guide the moving mechanism to approach the product 200 at different speeds to avoid the film removal fixture colliding with the product 200 due to excessive speed.
[0051] Optionally, the film removal fixture further includes a protective cover 5, which covers the cutting mechanism 2 and the clamping mechanism 3 and is fixed on the base 1. By providing the protective cover 5, a protective effect is played to prevent dust from entering the cutting mechanism 2 and the clamping mechanism 3 and affecting their normal operation. In addition, the film removal fixture further includes a wire extension board 6, a transfer junction box 7 and a mounting flange 8. The wire extension board 6 and the transfer junction box 7 are used to fix and comb the lines, and the mounting flange 8 is used to connect to the output end of the mobile mechanism.
[0052] The present invention also provides a film removal device, including a moving mechanism and a film removal clamp, wherein the output end of the moving mechanism is connected to the base 1. The film removal device can prevent tobacco auxiliary materials from being cut, and the film removal clamp in the film removal device has a simple and compact structure, low cost, and a high degree of integration. When removing the film 100, the moving mechanism drives the film removal clamp to move, so that the hook film member 21 contacts the product 200, and then continues to move the film removal clamp so that the hook film member 21 extends between the film 100 and the product 200 to separate the film 100 and the product 200. Then, the film removal clamp continues to move so that the cutting member 22 cuts the film 100 covered on the hook film member 21. After cutting, the moving mechanism moves the film removal clamp to a position where it is easy to clamp and peel the film 100. After reaching the position, the driving member 31 drives the second clamping member 33 to move so that the second clamping member 33 is close to the first clamping member 32 to clamp the film 100. After clamping, the moving mechanism drives the film removal clamp to move, and the film 100 is peeled off from the product 200. Optionally, the moving mechanism is a mechanical arm.
