[0044] This utility model embodiment provides a film-removing machine for removing the film from a roll assembly. The roll assembly includes a roll body and a thin film layer covering the outer surface of the roll body. The thin film layer includes an end-face film covering the end face of the roll body and a circumferential film covering the periphery of the roll body. In this embodiment, the roll body is taken as a cap roll for milk powder caps as an example. The cap roll includes multiple caps used as milk powder caps.

[0045] Figure 1 This is a perspective view of an embodiment of the film-removing machine of this utility model. The film-removing machine includes a conveying mechanism 300, a circumferential cutting mechanism 100, and a longitudinal cutting mechanism 200. The conveying mechanism 300 has a circumferential cutting station and a longitudinal cutting station, and the conveying mechanism 300 can drive the roll assembly R1 to move to the circumferential cutting station or the longitudinal cutting station. The circumferential cutting mechanism 100 is disposed at the circumferential cutting station, and the circumferential cutting mechanism 100 is used to separate the end face film from the roll body. The longitudinal cutting mechanism 200 is disposed at the longitudinal cutting station, and the longitudinal cutting mechanism 200 is used to separate the peripheral face film from the roll body.

[0046] According to an embodiment of the present invention, the film removal machine includes a conveying mechanism 300, a circumferential cutting mechanism 100, and a longitudinal cutting mechanism 200. The conveying mechanism 300 can automatically move the roll assembly R1 to the circumferential cutting station and the longitudinal cutting station. The film layer includes an end face film covering the end face of the roll body and a peripheral film covering the periphery of the roll body. When the roll assembly R1 moves to the circumferential cutting station, the circumferential cutting mechanism 100 performs a circumferential cutting process on the roll assembly R1, separating the end face film from the roll body. When the roll assembly R1 moves to the longitudinal cutting mechanism 200, the longitudinal cutting mechanism 200 performs a longitudinal cutting process on the roll assembly R1, separating the peripheral film from the roll body. After the film removal process by the circumferential cutting mechanism 100 and the longitudinal cutting mechanism 200, the end face film and the peripheral film are automatically removed, realizing the function of automatically removing the film layer on the outer surface of the roll body.

[0047] In some embodiments, the film removal machine further includes a frame 400, and the ring cutting mechanism 100 and the longitudinal cutting mechanism 200 can be mounted on the frame 400.

[0048] Figure 2 , Figure 3 This is a three-dimensional schematic diagram of the ring-cutting mechanism at different angles in one embodiment of the film-removing machine of this utility model. Figure 4 This is a side view of the ring-cutting mechanism in one embodiment of the film-removing machine of this utility model. In some embodiments, the ring-cutting mechanism 100 includes a first rolling drive assembly 110 and two ring-cutting assemblies 120.

[0049] The first rolling drive assembly 110 is capable of contacting the roll assembly R1 located at the circumferential cutting station. The first rolling drive assembly 110 is used to drive the roll assembly R1 to rotate around the central axis of the roll assembly R1. Two circumferential cutting assemblies 120 are respectively disposed at opposite ends of the roll assembly R1 located at the circumferential cutting station. Each circumferential cutting assembly 120 is used to separate the end face film of the corresponding end face of the roll body from the end face.

[0050] In some embodiments, the first rolling drive assembly 110 includes a first support roller 111, a second support roller 112, and a first rolling drive member 113. The first support roller 111 and the second support roller 112 together support the roll assembly R1 located at the circumferential cutting station. The first rolling drive member 113 is driveably connected to the first support roller 111, and the first rolling drive member 113 drives the roll assembly R1 to rotate around its central axis by driving the first support roller 111 to rotate. The first rolling drive member 113 is, for example, a rotary motor.

[0051] In some embodiments, each circumferential cutting assembly 120 includes a puncture assembly 121 and a first cutting blade assembly 122.

[0052] The piercing assembly 121 includes a piercing member 1211 and a first reciprocating drive member 1212 connected to the piercing member 1211. The first reciprocating drive member 1212 is capable of driving the piercing member 1211 to pierce between the end face and the end face film from the outer peripheral side of the end face of the roll body. In some embodiments, the piercing member 1211 is a component with a spiked structure, such as a piercing needle. The first reciprocating drive member 1212 is, for example, a cylinder, or other reciprocating drive members such as a linear module.

[0053] The first cutting assembly 122 includes a first cutter 1221 and a second reciprocating drive 1222 connected to the first cutter 1221. The second reciprocating drive 1222 is capable of driving the first cutter 1221 to be inserted from the outer periphery of the end face of the roll body into the space between the end face and the end face film. The second reciprocating drive 1222 is, for example, a cylinder, or other reciprocating drive such as a linear module.

[0054] In some embodiments, the second reciprocating drive 1222 drives the first cutter 1221 to move radially along the roll body, and the reciprocating movement direction of the piercing member 1211 intersects the reciprocating movement direction of the first cutter 1221.

[0055] When the first reciprocating drive 1212 drives the piercing member 1211 to pierce between the end face and the end face film, the first cutter 1221 can be easily inserted between the end face and the end face film. Therefore, during the film circumferential cutting process, after the first reciprocating drive 1212 drives the piercing member 1211 to pierce between the end face and the end face film, the second reciprocating drive 1222 drives the first cutter 1221 to be inserted between the end face and the end face film. Then, the first reciprocating drive 1212 resets, driving the piercing member 1211 to exit the end face. Afterwards, with the first cutter 1221 inserted between the end face and the end face film, the first rolling drive 113 drives the roll assembly R1 to roll, and the first cutter 1221 cuts the end face film, causing the end face film to separate from the roll body.

[0056] In some embodiments, the first cutter 1221 is a roller with a cutting edge on its outer peripheral edge. The first rolling drive 113 drives the roll assembly R1 to rotate.

[0057] In some embodiments, with the first cutter 1221 inserted between the end face and the end face film, the first rolling drive assembly 110 drives the roll assembly R1 to rotate by a first preset angle, causing the end face film to separate from the roll body. In some embodiments, the first preset angle is 180° to 360°. In one example, the first preset angle is 270°, which is 3 / 4 of a turn of the roll assembly R1. In some embodiments, the first preset angle may also be greater than 360°.

[0058] In some embodiments, each circumferential cutting assembly 120 further includes a first movable frame 123 and a first linear drive 124. The piercing assembly 121 and the first cutter 1221 assembly 122 are mounted on the first movable frame 123. The first linear drive 124 is connected to the first movable frame 123. The first linear drive 124 drives the first movable frame 123 to move axially along the roll assembly R1, thereby driving the piercing assembly 121 and the first cutter 1221 assembly 122 to move closer to or away from the end face of the roll body. The first linear drive 124 may be, for example, an electric push rod, or other linear drive components.

[0059] In some embodiments, each circumferential cutting assembly 120 further includes a positioning sensor 125. The positioning sensor 125 is connected to the first movable frame 123. The positioning sensor 125 is configured to be triggered when the piercing member 1211 and the first cutter 1221 move along the axial direction of the roll assembly R1 to the end face of the roll body, and generate a first positioning signal, which enables the first linear drive member 124 to pause its drive motion based on the first positioning signal.

[0060] In one example, the position sensor 125 is a proximity switch. In other embodiments, the position sensor 125 may be a proximity sensor, distance sensor, or other sensor capable of confirming the position status.

[0061] In some embodiments, each circumferential cutting assembly 120 further includes a third reciprocating drive 126. The third reciprocating drive 126 is disposed on the first movable frame 123, and the positioning sensor 125 is mounted on the third reciprocating drive 126. The third reciprocating drive 126 can move the positioning sensor 125 to a detection position or a avoidance position. In the detection position, at least a portion of the orthographic projection of the positioning sensor 125 onto the plane containing the end face of the coil body is located within the end face; in the avoidance position, the orthographic projection of the positioning sensor 125 onto the plane containing the end face of the coil body is located outside the end face. The third reciprocating drive 126 may be, for example, a cylinder, or other reciprocating drive such as a linear module.

[0062] In some embodiments, the ring-cutting mechanism 100 further includes a first pressing assembly 130. The first pressing assembly 130 includes a first pressing roller 131 and a fourth reciprocating drive member 132. The fourth reciprocating drive member 132 is connected to the first pressing roller 131. The fourth reciprocating drive member 132 is used to drive the first pressing roller 131 to a first separation position or a first pressing position, wherein, in the first separation position, the first pressing roller 131 is spaced apart from the material roll assembly R1, and in the first pressing position, the first pressing roller 131 contacts the circumferential surface of the material roll assembly R1 and presses the material roll assembly R1 against the first rolling drive assembly 110. The fourth reciprocating drive member 132 is, for example, a cylinder, or other reciprocating drive members such as a linear module.

[0063] The following describes the process of the circumferential cutting mechanism 100 of the above embodiment performing film circumferential cutting on the roll assembly R1: The transmission mechanism 300 transmits the roll assembly R1 to the circumferential cutting station. The first linear drive 124 drives the first movable frame 123 to move closer to the end face of the roll body, causing the piercing assembly 121 and the first cutter assembly 1221 to move closer to the end face of the roll body. When the positioning sensor 125 triggers and generates the first positioning signal, the first linear drive 124 stops driving. At this time, the piercing member 1211 and the first cutter 1221 have moved along the axial direction of the roll assembly R1 to the end face of the roll body. Then, the first reciprocating drive 1212 drives the piercing member 1211 to pierce between the end face and the end face film. Next, the second reciprocating drive 1222 drives the first cutter 1221 to insert between the end face and the end face film. Then, the first reciprocating drive 1212 resets, driving the piercing member 1211 to withdraw from the end face. Subsequently, the fourth reciprocating drive 132 drives the first pressing roller 131 to move to the first pressing position. The first pressing roller 131 contacts the circumferential surface of the roll assembly R1 and presses the roll assembly R1 against the first rolling drive assembly 110. Then, the first rolling drive 113 drives the first support roller 111 to rotate, causing the roll assembly R1 to rotate around the central axis of the roll assembly R1. That is, the first rolling drive assembly 110 drives the roll assembly R1 to roll, while the first cutter 1221 cuts the end face film, causing the end face film to separate from the roll body. In one example, with the first cutter 1221 inserted between the end face and the end face film, the first rolling drive assembly 110 drives the roll assembly R1 to rotate 270°. Then, the first rolling drive assembly 110 stops driving, the second reciprocating drive 1222 resets to make the first cutter 1221 exit the end face, and the fourth reciprocating drive 132 resets to make the first pressure roller 131 move to the first separation position. After that, the first rolling drive assembly 110 continues to drive the roll assembly R1 to rotate 225° and then stops driving. After that, the first linear drive 124 drives the first movable frame 123 to move away from the end face of the roll body to complete the film ring cutting process. The transmission mechanism 300 can transfer the roll assembly R1 to the next station.

[0065] The second rolling drive assembly 210 can contact the roll assembly R1 located at the longitudinal cutting station and drive the roll assembly R1 to rotate around the central axis of the roll assembly R1.

The film-tearing assembly 220 is used to penetrate between a portion of the peripheral film and the peripheral surface of the roll body and to pick up a portion of the peripheral film from the peripheral surface.

[0067] The second cutter assembly 230 is located on the outer periphery of the roll assembly R1. The second cutter assembly 230 is used to cut the peripheral film that is picked up from the peripheral surface in a direction parallel to the axial direction of the roll assembly R1.

A second linear drive 224 is connected to the second movable frame 221 and can drive the pin array 222 and the gripper 223 to move closer to or further away from the coil assembly R1. The second linear drive 224 can be, for example, a linear drive motor, or other linear drive components. A lifting drive 225 is connected to the pin array 222 and can drive the pin array 222 to move up and down. The lifting drive 225 can be, for example, a cylinder, or other reciprocating drive components.

[0070] In this embodiment, the second linear drive 224 can drive the needle row 222 to be inserted between a portion of the peripheral film and the peripheral surface of the roll body. The lifting drive 225 can drive the needle row 222 to move upward, so that the needle row 222 picks a portion of the peripheral film away from the peripheral surface, and the needle row 222 and the gripper 223 jointly hold the peripheral film.

[0071] like Figures 5 to 7 In some embodiments, the second rolling drive assembly 210 includes a third support roller 211, a fourth support roller 212, a second rolling drive member 213, and a brake member 214. The third support roller 211 and the fourth support roller 212 jointly support the roll assembly R1 located at the slitting station. The second rolling drive member 213 is driveably connected to the third support roller 211, and drives the roll assembly R1 to rotate around its central axis by driving the third support roller 211 to rotate. The second rolling drive member 213 is, for example, a rotary motor. The brake member 214 is disposed on the fourth support roller 212, and the brake member 214 is used to restrict the rolling of the fourth support roller 212 in a braking state.

[0072] In some embodiments, the slitting mechanism 200 further includes a first limiting component 240. In some embodiments, the slitting mechanism 200 further includes a second limiting component 250. In some embodiments, the slitting mechanism 200 further includes a second clamping component 260.

[0073] Figure 9 , Figure 10 This is a perspective view of the second cutting blade assembly, the first limiting assembly, the second limiting assembly, and the second pressing assembly at different angles in one embodiment of the film-removing machine of this utility model. In some embodiments, the second cutting blade assembly 230 includes a second cutting blade 231 and a fifth reciprocating drive member 232. The second cutting blade 231 is used to cut the peripheral film that has been lifted off the peripheral surface. In this embodiment, the second cutting blade 231 is a hot cutting blade, which cuts the peripheral film by heat melting. In some embodiments, the second cutting blade 231 is configured to cut the peripheral film at a cutting temperature of 110°C to 150°C. In one example, the cutting temperature of the second cutting blade 231 is configured to be 110°C; in another example, the cutting temperature of the second cutting blade 231 is configured to be 150°C; and in yet another example, the cutting temperature of the second cutting blade 231 is configured to be 120°C. By controlling the cutting temperature of the second cutting blade 231 within the aforementioned lower temperature range, the volatilization of harmful gases during the hot cutting process of the peripheral film can be reduced, and the odor generated during the hot cutting process of the peripheral film can be reduced. The fifth reciprocating drive 232 is connected to the second cutter 231, and the fifth reciprocating drive 232 is used to drive the second cutter 231 to reciprocate. The fifth reciprocating drive 232 can be, for example, a cylinder, or a linear module or other reciprocating drive.

[0074] In some embodiments, the slitting mechanism 200 further includes a first limiting component 240 disposed on the outer periphery of the roll assembly R1 located at the slitting station. The first limiting component 240 includes an extruder 241 and a third linear drive 242. The third linear drive 242 is used to drive the extruder 241 to a pressing position or a non-pressing position. In the pressing position, the extruder 241 presses against the roll assembly R1 to limit the rolling of the roll assembly R1. In the non-pressing position, the extruder 241 is spaced apart from the roll assembly R1. The third linear drive 242 is, for example, a cylinder, or a linear module, and in some other embodiments, it may be other linear drives.

[0075] In some embodiments, the slitting mechanism 200 further includes a second limiting component 250. The second limiting component 250 includes two blocking members 251 and a fourth linear drive member 252. The fourth linear drive member 252 is used to drive the two blocking members 251 to a blocked position or a non-blocked position. In the blocked position, the two blocking members 251 respectively contact the two end faces of the roll body. In the non-blocked position, the two blocking members 251 are spaced apart from the roll assembly R1. The fourth linear drive member 252 is, for example, a cylinder, or a linear module, and in some other embodiments, it may be other linear drive members.

[0076] In some embodiments, the longitudinal cutting mechanism 200 includes a first limiting component 240 and a second limiting component 250, and the first limiting component 240 and the second limiting component 250 share a linear drive member, that is, the third linear drive member 242 of the first limiting component 240 is reused as the fourth linear drive member 252 of the second limiting component 250. The third linear drive member 242 (that is, the fourth linear drive member 252) can drive the extruder 241 to move to the extrusion position or the non-extrusion position, and can also drive the two blocking members 251 to move to the blocking position or the non-blocking position.

[0077] In some embodiments, the slitting mechanism 200 further includes a second pressing assembly 260. The second pressing assembly 260 includes a second pressing roller 261 and a sixth reciprocating drive member 262. The sixth reciprocating drive member 262 is connected to the second pressing roller 261. The sixth reciprocating drive member 262 is used to drive the second pressing roller 261 to a second separation position or a second pressing position. In the second separation position, the second pressing roller 261 is spaced apart from the roll assembly R1. In the second pressing position, the second pressing roller 261 contacts the circumferential surface of the roll assembly R1 and presses the roll assembly R1 against the second rolling drive assembly 210. The sixth reciprocating drive member 262 is, for example, a cylinder, and in some other embodiments, it may be other reciprocating drive members.

[0078] The following describes the process of the slitting mechanism 200 performing film slitting on the roll assembly R1 in the above embodiment: The conveying mechanism 300 conveys the roll assembly R1 to the slitting station. The third linear drive 242 drives the extruder 241 to the extrusion position, and the extruder 241 presses against the roll assembly R1 to limit its rolling. The brake 214 enters the braking state, restricting the rolling of the fourth support roller 212. At this time, both the extruder 241 and the fourth support roller 212 prevent the roll assembly R1 from rolling. Then, the second linear drive 224 drives the needle array 222 to be inserted between a portion of the peripheral film and the peripheral surface of the roll body. Then, the third linear drive 242 drives the extruder 241 to the non-extrusion position, and the extruder 241 and the roll assembly R1 are spaced apart. The brake 214 exits the braking state. Next, the lifting drive 225 drives the needle array 222 upward, causing the needle array 222 to lift part of the peripheral film away from the peripheral surface, and the needle array 222 and the gripper 223 jointly hold the peripheral film. Then, the fifth reciprocating drive 232 drives the second cutter 231 closer to the peripheral film. The second cutter 231 cuts the lifted peripheral film along a direction parallel to the axial direction of the roll assembly R1. After cutting, the fifth reciprocating drive 232 resets, driving the second cutter 231 away from the peripheral film. Then, the second linear drive 224 drives the needle array 222 and the gripper 223 to move a first preset distance away from the roll assembly R1. In one example, the first preset distance is 100mm. Then, the fourth linear drive 252 drives the two blocking members 251 to move to the blocking position. The two blocking members 251 respectively contact the two end faces of the roll body to prevent the covers on both end faces of the roll body from falling off. Subsequently, the second rolling drive assembly 210 drives the roll assembly R1 to roll in the first rolling direction, causing the peripheral film to disengage from the needle array 222 and the gripper 223. Then, the second rolling drive assembly 210 drives the roll assembly R1 to roll in the second rolling direction, causing the peripheral film to separate from the roll body and guide the film layer into a preset position, such as into a waste bin. At this point, the film longitudinal cutting process is completed, all film layers have been removed, and the roll body is obtained at the longitudinal cutting station. The conveying mechanism 300 can transport the roll body away from the longitudinal cutting station.

[0079] Figure 11 This is a perspective view of the transmission mechanism in one embodiment of the film-removing machine of this utility model. In some embodiments, the transmission mechanism 300 includes a transfer component 310 and a fifth linear drive component 320. The transfer component 310 is used to carry the roll assembly R1 or the roll body. The transfer component 310 is connected to the fifth linear drive component 320. The fifth linear drive component 320 can drive the transfer component 310 to move linearly and move the transfer component 310 to the ring cutting station or the longitudinal cutting station. The fifth linear drive component 320 is, for example, a linear drive motor, and in some other embodiments, it may be other linear drive components.

[0080] In one example, the transfer assembly 310 includes a movable table 311, a lifting assembly 312, a clamping member 313, and a clamping drive 314. The movable table 311 can move under the drive of the fifth linear drive 320. The clamping member 313 is mounted on the movable table 311 through the lifting assembly 312. The lifting assembly 312 can drive the clamping member 313 to move up and down relative to the movable table 311. The clamping drive 314 is connected to the clamping member 313 and can drive the clamping member 313 to clamp and release the roll assembly R1 or the roll body.

[0081] In one example, after the conveying mechanism 300 carries the roll assembly R1 to be de-filmed, it first moves the roll assembly R1 to the ring-cutting station, where the ring-cutting mechanism 100 performs ring-cutting on the roll assembly R1. Then, the conveying mechanism 300 moves the roll assembly R1 to the longitudinal cutting station, where the longitudinal cutting mechanism 200 performs longitudinal cutting on the roll assembly R1, resulting in a roll body with the film layer removed. The conveying mechanism 300 then transports the roll body to the discharge station.

All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
