In addition, the technical features described below in the different embodiments of the present application may be combined with each other as long as they do not collide with each other.

Fig. 1 to 15 exemplarily show the structures of the film removing system and the film removing apparatus in the present application.

Referring to fig. 1-15, in the present application, a membrane removal system 100 includes a transport apparatus 20 and a membrane removal apparatus 10. The conveyor apparatus 20 is used to convey stacks 30. Wrapping film 40 is wrapped around stack 30. The film removing apparatus 10 is for removing the packaging film 40 on the stack 30, which is located on one side of the conveying apparatus 20 along a first direction W perpendicular to the up-down direction H, so that the stack 30 on the conveying apparatus 20 is located on one side of the film removing apparatus 10 along the first direction W.

Based on the provided conveying apparatus 20 and film removing apparatus 10, the film removing system 100 can realize automatic conveyance of the stack 30 and automatic removal of the packaging film 40 on the stack 30.

1-3, the packaging film 40 on the stack 30 is a non-integral wrapping type packaging film which is not wrapped around the end surfaces of the upper and lower ends of the stack 30, but is wrapped only between the upper and lower ends of the stack 30.

Because of the complex stack design, the heights of stacks 30 of different sizes are different, and the locations of the packaging films 40 on the stacks 30 are different, and the same product may be produced by multiple production lines, the locations of the packaging films 40 on the stacks 30 are not necessarily the same when the same product is produced by different production lines, and therefore, the locations of the non-integral packaging films are varied.

In the related art, the film removing device 10 generally can only remove the integral packaging film, but for the non-integral packaging film which occurs recently, no special film removing device 10 exists, and the same film removing device 10 cannot be utilized to effectively remove the packaging film with different specifications and different positions.

In view of the above, the present application improves the structure of the membrane removal device 10.

Referring to fig. 1 to 15, in the present application, a film removing apparatus 10 includes a frame 1, a height detecting device 2, and a film breaking device 3. The height detecting device 2 is provided on the rack 1, and detects the height position of the packaging film 40 wound between the upper and lower ends of the stack 30 on the stack 30 located on one side of the rack 1 in the first direction W. The film breaking device 3 is liftably disposed on the frame 1 and includes a film breaking member 31 for breaking the packaging film 40 detected by the height detecting device 2.

Through setting up high detection device 2, detect the high position of non-integral packaging film 40 on the goods buttress 30 for film breaking device 3 can be accurate and high-efficient break off to the packaging film 40 of different high positions, consequently, make things convenient for the removal of the non-whole wound packaging film of many standard, different positions, this is favorable to improving the work flexibility that removes membrane equipment 10 and removes membrane system 100, enlarges the application scope that removes membrane equipment 10 and removes membrane system 100, promotes the removal membrane efficiency that removes membrane equipment 10 and removes membrane system 100.

To enable detection of the height position of the packaging film 40, in some embodiments, referring to fig. 1, the height detection device 2 includes a first detection member 21 and a second detection member 22, the first detection member 21 detecting the height of the stack 30, and the second detection member 22 detecting the height position of the packaging film 40 on the stack 30 after the first detection member 21 detects the height of the stack 30.

In the above-described scheme, the height detecting device 2 does not directly detect the packaging film 40 to obtain the height position of the packaging film 40, but adopts a two-stage detection method to detect the height position of the packaging film. The first detecting piece 21 detects the stack height, which is the first level detection, is equivalent to one coarse positioning, and can be used as the detection base of the second detecting piece 22; the second detecting member 22 detects the height position of the packaging film 40 on the stack 30 based on the detected stack height after the first detecting member 21 detects the stack height, which is the second level detection, and corresponds to the second level fine positioning, so that the height position of the packaging film 40 on the stack 30 can be finally determined. The two-stage detection method of coarse and fine is beneficial to improving the detection precision, and the second detection piece 22 only needs to detect within the stack height range determined by the first detection piece 21, and full-stroke detection is not needed, for example, the second detection piece 22 only needs to detect within a preset height range (which can be preset and corresponds to the maximum height range where the packaging film 40 may be located) below the stack top detected by the first detection piece 21, so that the height position of the packaging film 40 on the stack 30 can be determined, thereby being beneficial to shortening the detection time and improving the detection efficiency.

The packaging film 40 is wound on the stack 30 in a generally high range, for example, a deviation exists between the two uppermost containers, and may be upper or lower, so that a height range of the packaging film covering all conditions may be predetermined, and then the second detecting member 22 may be detected in a corresponding range, so that the second detecting member 22 does not need to detect in the whole stack height range any more, and the detecting efficiency and detecting accuracy may be effectively improved.

Therefore, by arranging the first detecting element 21 and the second detecting element 22, the two-stage detection mode of firstly coarsening and then finely detecting is adopted, so that the detection of the height position of the packaging film 40 can be efficiently and accurately realized, and the removal of non-integral winding packaging films with multiple product gauges and different positions is facilitated.

As an example of the first detecting member 21 described above, referring to fig. 1, the first detecting member 21 includes a first photosensor 211. The first photosensor 211 detects the stack height by sending light to the stack 30. Specifically, whether the stack 30 is detected may be determined by determining whether the light transmitted by the first photoelectric sensor 211 is blocked by the stack 30, so as to further realize the detection of the stack height (i.e., stack height).

In addition, as an example of the second detecting member 22 described above, referring to fig. 1, the second detecting member 22 includes a color patch sensor 221. The color patch sensor 221 detects the height position of the packaging film 40 by projecting laser light to the packaging film 40. Because the reflection degrees of the packaging film 40 and the stack 30 are different, the color code sensor 221 can determine whether the packaging film 40 is film or film-free according to different reflection of light when the packaging film is film-free, so as to realize detection of the height position of the packaging film 40. By using the color scale sensor 221, the detection of the packaging film 40 can be conveniently and accurately realized, and particularly, the difficult problem of detecting the transparent packaging film 40 can be effectively solved. The transparent packaging film 40 allows light to pass therethrough, and thus, detection of the packaging film 40 is generally difficult to achieve with a photoelectric sensor. By using the color code sensor 221, the corresponding problems can be effectively solved by utilizing the difference of the reflection degree of the packaging film 40 and the stack 30, and the detection of the packaging film 40 can be conveniently and accurately realized.

In case the second detecting member 22 comprises a color patch sensor 221, referring to fig. 1, the height detecting device 2 may further comprise an auxiliary light source 23, the auxiliary light source 23 providing auxiliary illumination for the color patch sensor 221. In this way, the influence of the change of the ambient light on the detection result of the color mark sensor 221 can be reduced, and especially, the insufficient ambient light can be prevented, so that the color mark sensor 221 is difficult to effectively detect, and the detection of the height position of the packaging film is more accurate and reliable.

In embodiments where the height detection device 2 includes a second detection member 22, the second detection member 22 may be configured to be extendable or retractable relative to the frame 1 in the first direction W to be adjacent to or away from the wrapping film 40 on the stack 30. Thus, on the one hand, when needed, the second detecting member 22 can be made to be close to the packaging film 40 to accurately detect the height position of the packaging film 40, and on the other hand, before and after detection, the second detecting member 22 can be far away from the packaging film 40 to avoid, so that the detection of the height position of the packaging film is conveniently realized by the second detecting member 22, and the orderly execution of other steps is also convenient. In particular, in the case where the second detecting member 22 includes the color patch sensor 221, the color patch sensor 221 performs a detecting function that requires a certain distance from the packaging film 40, and therefore, the second detecting member 22 is disposed so as to be able to approach or separate from the packaging film 40, which is more convenient for the color patch sensor 221 to accurately perform detection of the packaging film 40 without affecting other operations.

In the foregoing embodiments, the height detecting device 2 may be provided on the frame 1 in a liftable manner. In this way, the height detection device 2 is more convenient to detect the packaging films 40 at different height positions, and the height detection device 2 can descend to a lower detection position only when detection is needed, and is positioned at a higher initial position before detection starts, so that avoidance is performed, and further steps such as transportation of the goods stack 30 are facilitated.

The liftable height detection device 2 can be lifted with the film breaking device 3 successively or synchronously. When the height detection device 2 and the film breaking device 3 synchronously lift, the film breaking device 3 conveniently moves to the height of the packaging film 40 after the height detection device 2 detects the packaging film 40, and breaks the packaging film 40 in time. The film breaking device 3 is lifted when the height detection device 2 is lifted, so that additional occupied time is not needed, and the efficiency is improved.

In the foregoing embodiments, the film breaking device 3 breaks the packaging film 40 by the film breaking member 31. The film breaking member 31 may be used in various ways to break the packaging film 40. For example, in some embodiments, the film breaking member 31 includes a heating wire 311 (see fig. 8), and the heating wire 311 fuses the packaging film 40 to break the packaging film 40, and at this time, the film breaking member 31 fuses the packaging film 40 by heating. For another example, in other embodiments, the film breaking member 31 includes a cutter (not shown) that cuts the packaging film 40 to break the packaging film 40, and at this time, the film breaking member 31 uses a cutter to break the packaging film 40. For another example, in some embodiments, the film breaking member 31 includes both a cutter and a heating wire 311 to break the packaging film 40 in both a cutting and a thermal fusing manner.

As an example of the film breaking device 3 of the foregoing embodiments, referring to fig. 6 and fig. 8 and 9, the film breaking device 3 includes not only the film breaking member 31 but also the film breaking telescopic driving mechanism 32, and the film breaking telescopic driving mechanism 32 is drivingly connected to the film breaking member 31 and drives the film breaking member 31 to extend or retract in the first direction W with respect to the frame 1 so as to bring the film breaking member 31 close to or away from the packaging film 40 on the stack 30. Based on this, the film breaking member 31 can automatically approach or separate from the packaging film 40 on the stack 30 under the driving of the film breaking telescopic driving mechanism 32, so as to flexibly and conveniently meet different requirements when film breaking is needed and when film breaking is not needed, and improve the efficiency.

To further improve efficiency, the film removing apparatus 10 may include not only the frame 1, the height detecting device 2, and the film breaking device 3, but also the film removing device 4, the film removing device 4 being liftably provided on the frame 1, and including a film removing mechanism 41, the film removing mechanism 41 being for engaging the packaging film 40 before and/or after the film breaking device 3 breaks the packaging film 40, and separating the packaging film 40 from the stack 30.

Wherein, the film removing device 4 separates the packaging film 40 from the stack 30 before the packaging film 40 is broken by the film breaking device 3, so that the packaging film 40 is not attached to the stack 30 any more but separated from the stack 30 when the film breaking device 3 breaks the packaging film 40, thus the film breaking device 3 can only act on the packaging film 40 to break the packaging film 40 more time-saving and labor-saving, and is beneficial to preventing the film breaking device 3 from damaging the stack 30.

And the film removing device 4 separates the packaging film 40 from the goods stack 30 after the packaging film 40 is broken by the film breaking device 3, namely, the broken packaging film 40 is taken down from the goods stack 30, so that the packaging film 40 can be automatically removed from the goods stack 30, and compared with the situation that the broken packaging film 40 falls off automatically or the broken packaging film 40 is manually taken down under the action of gravity, the film removing device 4 has higher automation degree and is more beneficial to improving the efficiency, and the film removing device 10 can integrate the functions of detecting, breaking and removing the film into a whole, has higher integration degree and richer functions.

Wherein the film removing device 4 engages with the packaging film 40 and separates the packaging film 40 by the film removing mechanism 41. As an example of the film removing mechanism 41, the film removing mechanism 41 may include a gripping mechanism that grips the packaging film 40 to engage with the packaging film 40; alternatively, the film removing mechanism 41 may include a film sucking device 411, the film sucking device 411 sucking the packaging film 40 to be joined with the packaging film 40; still alternatively, the film removing mechanism 41 may include both a clamping mechanism and a film sucking device 411 to engage the packaging film 40 in both clamping and sucking modes.

In the film removing apparatus 10, the number of the film removing devices 4 is not limited, and may be one, two or more. For example, referring to fig. 1-5, in some embodiments, the film removal apparatus 10 includes at least two film removal devices 4, the at least two film removal devices 4 being spaced apart to engage different portions of the packaging film 40. Based on this, when the packaging film 40 needs to be separated, the film removing device 10 and the packaging film 40 have more joint parts, so the joint between the two is firmer, and the packaging film 40 and the stack 30 are more conveniently and reliably separated by the film removing device 10. Moreover, the film removing apparatus 10 is engaged with different portions of the packaging film 40 by different film removing devices 4, and also enables the different film removing devices 4 to straighten portions between the different engaged portions of the packaging film 40, facilitating other treatments of the removed packaging film 40, such as placing the removed packaging film 40 on a film winding mechanism 5 to be mentioned later.

When the film removing apparatus 10 includes at least two film removing devices 4, the film breaking device 3 may be located between different film removing devices 4, or may be located at one side of all the film removing devices 4. For example, referring to fig. 1-3, in some embodiments, the film breaking device 3 is located on one side of at least two film removing devices 4 along the arrangement direction of the at least two film removing devices 4. Thus, referring to fig. 2, the film breaking device 3 locates the position C where the packaging film 40 breaks away outside the position (e.g., the a and B positions in fig. 2) where the packaging film 40 is joined to the different film removing devices 4, so that after the packaging film 40 breaks away, the portion of the packaging film 40 located between the different film removing devices 4 can be better maintained (e.g., straightened) by the film removing devices 4, thereby facilitating other processing of the removed packaging film 40 by the film removing devices 4, such as placing the removed packaging film 40 on the film winding mechanism 5, which will be mentioned later.

In the foregoing embodiments, referring to fig. 6, the film removing device 4 may further include not only the film removing mechanism 41, but also a film removing telescopic driving mechanism 42, where the film removing telescopic driving mechanism 42 is drivingly connected to the film removing mechanism 41, and drives the film removing mechanism 41 to extend or retract in the first direction W relative to the frame 1, so that the film removing mechanism 41 approaches or separates from the packaging film 40 on the stack 30. Based on this, the film removing mechanism 41 can automatically approach or separate from the packaging film 40 on the stack 30 under the driving of the film removing telescopic driving mechanism 42, so as to flexibly and conveniently meet different requirements when the packaging film 40 is separated from the stack 30, and improve the efficiency. When the film removing apparatus 10 includes at least two film removing mechanisms 41, each film removing mechanism 41 is equipped with a film removing telescopic driving mechanism 42, so that each film removing mechanism 41 is driven by a different film removing telescopic driving mechanism 42, and can be independently extended or retracted, so that different film removing mechanisms 41 can be conveniently retracted before the film breaking device 3 breaks the packaging film 40, the pulling force applied by the packaging film 40 before breaking is reduced, and the falling risk of the unbroken packaging film 40 is reduced.

In addition, in order to improve the operational reliability of the film removing device 4, as a further improvement of the film removing device 4 in the foregoing embodiments, referring to fig. 5 and 10, the film removing device 4 further includes a first in-place detecting device 43, and the first in-place detecting device 43 detects whether the packaging film 40 is located on the film removing mechanism 41. Thus, the packaging film 40 can be prevented from falling off from the film removing mechanism 41, and the operation reliability of the film removing device 4 can be effectively improved.

With continued reference to fig. 5 and 10, as an example of the first presence detection device 43, the first presence detection device 43 includes at least one of an ultrasonic sensor 431 and a pressure sensor 432. Wherein the ultrasonic sensor 431 detects whether the packaging film 40 is located on the film removing mechanism 41 by emitting ultrasonic waves to the packaging film 40; the pressure sensor 432 detects whether the packaging film 40 is positioned on the peeling mechanism 41 by detecting the pressure of the peeling mechanism 41. When the first in-place detecting device 43 includes both the ultrasonic sensor 431 and the pressure sensor 432, the first in-place detecting device 43 can perform double detection on the packaging film 40, the detection result is more accurate and reliable, and the packaging film 40 can be more effectively prevented from falling off from the film removing mechanism 41.

Since the packaging film 40 is generally soft and is easily carried on the stack 30 during the separation of the packaging film 40 by the film removing device 4, in order to solve the corresponding problem, the film removing apparatus 10 comprises, in some embodiments, a blowing device 72 for blowing the packaging film 40 during the separation of the packaging film 40 from the stack 30 by the film removing device 4, see fig. 1-4. In the process of separating the packaging film 40 by the film removing device 4, the air blowing device 72 is used for blowing air, so that the packaging film 40 can be effectively prevented from being hung on the stack 30, and particularly, the packaging film 40 can be effectively prevented from being hung on the stack 30 in the process of taking the broken packaging film 40 off the stack 30 by the film removing device 4, so that the smooth removal of the packaging film 40 is not affected. Moreover, the stack 30 is not generally completely flat, but may have sharp corners due to local projections and depressions of the container, in which case the packaging film 40 is more easily hung on the stack 30 and is difficult to remove, and thus, the blowing device 72 is provided to blow the packaging film 40, which is more significant.

Wherein the blowing device 72 may include a gas tap 721, and the gas tap 721 blows the packaging film 40. Also, the number of air nozzles 721 in the air blowing device 72 may be one, two or more. When the blowing device 72 includes at least two air nozzles 721, in some embodiments, the at least two air nozzles 721 are spaced along the periphery of the stack 30 to blow the packaging film 40 at different positions, so that the blowing device 72 can blow the periphery of the packaging film 40, and can more reliably prevent the packaging film 40 from being hung on the stack 30, thereby more effectively improving the separation efficiency of the packaging film.

In addition, in order to facilitate blowing by the blowing device 72 during separation of the packaging film 40 by the film removing device 4, referring to fig. 1 to 4, in some embodiments, the film removing apparatus 10 includes a frame 71, the frame 71 is connected to the frame 1 and is lifted and lowered in synchronization with the film removing device 4, the frame 71 allows the stack 30 to pass through, and the blowing device 72 is provided on the frame 71.

In the above arrangement, since the air blowing device 72 is disposed on the frame 71, and the frame 71 and the film removing device 4 are lifted synchronously, the air blowing device 72 and the film removing device 4 can be lifted synchronously, so that the air blowing device 72 and the film removing device 4 can reach the height position of the packaging film 40 synchronously, and then air can be blown timely in the process of separating the packaging film 40 by the film removing device 4, thereby improving the efficiency. Moreover, since the frame 71 allows the stack 30 to pass through, the provided frame 71 and the air blowing device 72 do not interfere with the stack 30, the lifting mechanism of the film removing apparatus 10 can be conveniently lifted, and the air blowing device 72 can conveniently achieve a good air blowing effect, in particular, in this case, all the air nozzles 721 of the air blowing device 72 are only required to be distributed on the frame 71 at intervals, so that the air blowing can be realized at intervals around the periphery of the stack 30, and the packaging film 40 is blown from the periphery, thereby reliably preventing the packaging film 40 from being hung.

In the foregoing embodiments, the film removing device 4 and the film breaking device 3 are both liftable to facilitate breaking and separating the packaging film 40 at different height positions. The lifting of the film removing device 4 and the film breaking device 3 may be synchronous or asynchronous. When the film removing device 4 and the film breaking device 3 are lifted synchronously, the efficiency is higher, and the structure is more beneficial to simplification.

For example, referring to fig. 1-4, in some embodiments, the film removing apparatus 10 includes a lifting frame 13, the lifting frame 13 is liftably disposed on the frame 1, and the film removing device 4 and the film breaking device 3 are both disposed on the lifting frame 13, so that the film removing device 4 and the film breaking device 3 are lifted synchronously. Like this, go membrane device 4 and disconnected membrane device 3 all integrate on crane 13, only need drive crane 13 go up and down, can realize going up and down in step of membrane device 4 and disconnected membrane device 3, and not only the lift synchronism is better, moreover, need not to be equipped with respectively for going membrane device 4 and disconnected membrane device 3 and go up and down actuating mechanism, consequently, still be favorable to simplifying the structure.

In the case where the lifting frame 13 is provided, other mechanisms that are lifted in synchronization with the film breaking device 3 or the film removing device 4, such as the height detecting device 2, the frame 71, the air blowing device 72, and a stopper 73 and a take-up mechanism 6 that will be mentioned later, may also be provided on the lifting frame 13 to achieve more synchronized lifting based on a simpler structure.

The packaging film 40 removed from the stack 30 by the film removal device 4 takes up a relatively large space if not handled, and thus, in order to save space, the film removal apparatus 10 in some embodiments comprises not only the film removal device 4 but also a film winding mechanism 5, which is arranged on the frame 1 and which is used to wind the packaging film 40 removed from the stack 30 by the film removal device 4 into a film roll, see fig. 1-7. Thus, the film removing apparatus 10 integrates not only the packaging film height detecting, film breaking and film removing functions, but also the film rolling function, so that the packaging film 40 separated from the stack 30 can be rolled up to reduce space occupation.

In order to perform the film winding function of the film winding mechanism 5, see fig. 3 and fig. 12 and 13, in some embodiments, the film winding mechanism 5 includes a winding mechanism 51, and the winding mechanism 51 is rotatably disposed on the frame 1, and winds the packaging film 40 removed from the stack 30 by the film removing device 4 into a film roll during rotation. In this way, the removed packaging film 40 can be wound into a film roll by the rotating winding mechanism 51, thereby realizing the corresponding film winding function. The winding mechanism 51 may be driven by the winding driving mechanism 52 to automatically rotate the winding mechanism 51, so as to automatically wind the packaging film 40 into a roll, thereby improving efficiency.

As an example of the winding mechanism 51, referring to fig. 12 and 13, in some embodiments, the winding mechanism 51 includes a first winding lever 511 and a second winding lever 512, the first winding lever 511 and the second winding lever 512 are rotatably provided on the frame 1, and an accommodating space 513 is provided between the first winding lever 511 and the second winding lever 512 so that the packaging film 40 removed from the stack 30 by the peeling device 4 can be placed in the accommodating space 513 between the first winding lever 511 and the second winding lever 512, and wound into a film roll during rotation of the first winding lever 511 and the second winding lever 512. Therefore, the packaging film 40 which is originally unwound can be wound into a roll to form a film roll by only putting the packaging film 40 into the accommodating space 513 between the first roll rod 511 and the second roll rod 512 and driving the first roll rod 511 and the second roll rod 512 to rotate.

The packaging film 40 may be manually placed in the accommodating space 513, or may be automatically placed in the accommodating space 513 by the film removing device 4, so as to further improve efficiency. In the case where the packaging film 40 is placed in the accommodating space 513 by the film removing device 4, referring to fig. 1 to 3, the film winding mechanism 5 may be disposed below the film removing device 4, so that the film removing device 4 only needs to descend all the time, and the two operations of removing the packaging film 40 and placing the removed packaging film 40 in the accommodating space 513 can be sequentially completed, which is more convenient to control and has higher efficiency. Of course, in other embodiments, the film winding mechanism 5 may be disposed above the film removing device 4, so that the film removing device 4 may place the removed packaging film 40 into the accommodating space 513 by moving upward.

In order to successfully and efficiently complete the film winding process, referring to fig. 1-4, in some embodiments, the film removing apparatus 10 includes a stopper 73, where the stopper 73 stops the packaging film 40 during the winding of the packaging film 40 by the film winding mechanism 5 to prevent the packaging film 40 from being separated from the film winding mechanism 5 during the winding process. In this way, the packaging film 40 is not easily separated from the film winding mechanism 5 during winding by the stopper 73, but can be reliably held on the film winding mechanism 5, so that the film winding mechanism 5 is more convenient to wind the packaging film into a film roll, and the efficiency is higher.

The stopper 73 may stop the packaging film 40 from the top to the bottom, from the bottom to the top, or from both the top and the bottom.

As an example, referring to fig. 1 to 4, the stopper 73 stops the packaging film 40 at the upper side during the winding of the packaging film 40 by the film winding mechanism 5 to prevent the packaging film 40 from being separated from the film winding mechanism 5 from the upper side during the winding. In this way, the wrapping film 40 does not separate from the film winding mechanism 5 from above by the stopper 73, and the film winding mechanism 5 can wind the wrapping film 40 into a film roll more efficiently.

In the embodiment where the stopper 73 stops the packaging film 40 from above, referring to fig. 1 to 3, the stopper 73 may be disposed on the frame 1 in a liftable manner, so that the stopper 73 is conveniently lowered to a stop position when stopping is required, pressed on the film roll to achieve a stop effect from top to bottom, and when stopping is not required, the stopper 73 may be kept at a higher position to avoid other structural components, so that other structural components are conveniently moved.

The lifting of the stopping piece 73 can be synchronous with the film removing device 4, so that when the film removing device 4 puts the packaging film 40 on the film winding mechanism 5, the stopping piece 73 synchronously reaches the stopping position to stop, the efficiency is improved, and a good stopping effect is achieved.

In addition, referring to fig. 3, in the case where the film winding mechanism 5 includes the winding driving mechanism 52, the film winding mechanism 5 may further include a shielding member 53, the shielding member 53 being located above the winding driving mechanism 52, and at least part of the winding mechanism 51 being located above the shielding member 53. Based on this, the protector 53 can support and stop the packaging film 40 from below during the winding process, preventing the packaging film 40 from entering the winding drive mechanism 52 so as not to affect the smooth completion of the winding process.

Therein, referring to fig. 3, in some embodiments, the guard 53 is provided with a downwardly concave groove 531. The grooves 531 are provided to facilitate insertion of a hand or tool (for example, a second gripper 62 of the take-up mechanism 6 to be mentioned later), and thus, to facilitate removal of the wound film roll from the winding mechanism 51 after the winding mechanism 51 winds the packaging film 40 into a film roll.

The roll-off action may be accomplished manually by a worker or automatically by the film removal apparatus 10.

Wherein, for facilitating the completion of the roll-off action, referring to fig. 12 and 13, in some embodiments, the film removing apparatus 10 includes a second in-place detecting device 54, and the second in-place detecting device 54 detects whether the film roll is located on the film winding mechanism 5. In this way, the take-up operation can be performed only when the second in-place detecting device 54 detects that the film roll is located on the film winding mechanism 5, so that the film roll cannot be taken out smoothly due to the unexpected detachment of the film roll from the film winding mechanism 5. The second in-situ detecting device 54 may take a variety of configurations. Illustratively, referring to FIGS. 12 and 13, the second in-situ detection device 54 includes a second photosensor 541. Since the packaging film 40 is not transparent after being wound into a film roll, the second photoelectric sensor 541 can smoothly detect whether the film roll is in place, and the packaging film has a simple structure, low cost and high accuracy.

In addition, to achieve an automatic take-up and roll action, referring to fig. 1-7, in some embodiments, the film removal apparatus 10 includes a take-up mechanism 6, the take-up mechanism 6 being disposed on the frame 1 and configured to take the film roll off the film take-up mechanism 5. Like this, remove membrane equipment 10 not only integrate packaging film height detection, broken film, remove membrane and roll up membrane function, but also integrate and get a roll the function, can realize the automation of film roll and take off, the function is richer, and efficiency is higher.

The winding mechanism 6 may take various structural forms.

For example, in some embodiments, the take-up mechanism 6 includes a robotic arm that removes a film roll from the film roll mechanism 5 by grasping the film roll.

For another example, referring to fig. 14 and 15, in some embodiments, the film take-up mechanism 6 includes a first nip member 61, a second nip member 62, and a swing driving mechanism 63, the first nip member 61 and the second nip member 62 being disposed in sequence in a top-to-bottom direction and opposing each other, the swing driving mechanism 63 being drivingly connected to the first nip member 61 and the second nip member 62 and driving the first nip member 61 and the second nip member 62 to swing relatively in a top-to-bottom direction H to nip or release the film roll, the take-up mechanism 6 being liftably provided on the frame 1 to drive the film roll sandwiched between the first nip member 61 and the second nip member 62 off the film unwinding mechanism 5. In this way, the first clamping roller 61 and the second clamping roller 62 swing in opposite directions in the up-down direction H to clamp the film roll and drive the film roll to rise, so that the film roll can be taken down from the film winding mechanism 5, and the film winding mechanism is simple and efficient. In addition, the first and second winding members 61 and 62 swing reversely in the up-down direction H, and the film roll can be released, so that the removed film roll can be conveniently subjected to subsequent processing such as collection. Wherein, first clamp roll piece 61 and second clamp roll piece 62 centre gripping membrane roll, also be difficult to damage the membrane roll, conveniently follow-up to the membrane roll reuse.

The first and second crimp members 61 and 62 may take various forms such as a plate or a rod. For example, referring to fig. 14 and 15, in some embodiments, the first crimp 61 and/or the second crimp 62 include at least two crimp bars 611, the at least two crimp bars 611 being spaced apart. In this way, the first and second clamping members 61 and 62 can clamp the film roll between the first and second roll rods 511 and 512 more conveniently, and the first and/or second clamping members 61 and 62 can be engaged with the film roll at different positions by different clamping rods 611 to apply force to the film roll at least at two positions, so that the film roll can be firmly engaged with the film roll by the more convenient take-up mechanism 6, and the film can be taken up smoothly and reliably. In addition, the first rolling piece 61 is configured to comprise a rolling rod 611, so that the first rolling piece 61 is particularly convenient to be matched with the groove 531 on the protective piece 53 of the film rolling mechanism 5, and the rolling and taking operation is smoothly realized.

To facilitate driving the first and second nip members 61, 62 to oscillate relatively in the up-down direction H, the film roll is clamped or released, see fig. 14, and in some embodiments, the oscillation drive mechanism 63 includes a first oscillation drive mechanism 631 and a second oscillation drive mechanism 632. The first swing driving mechanism 631 is drivingly connected to the first roll clamping member 61 to drive the first roll clamping member 61 to swing downward so that the first roll clamping member 61 and the second roll clamping member 62 clamp the film roll on the film rolling mechanism 5. The second swing driving mechanism 632 is drivingly connected to the second reel holder 62 to drive the second reel holder 62 to swing downward, so that the first reel holder 61 and the second reel holder 62 release the film roll separated from the film unwinding mechanism 5. In this way, in the working process, the coil taking mechanism 6 can be controlled to reach the coil taking height position firstly, so that the second coil clamping piece 62 is positioned below the film coil, then the first swing driving mechanism 631 is controlled to act, the first coil clamping piece 61 is driven to swing downwards to clamp the film coil, then the first coil clamping piece 61 and the second coil clamping piece 62 are controlled to drive the film coil to rise together, so that the film coil leaves the coil mechanism 5, then after the first coil clamping piece 61 and the second coil clamping piece 62 roll the film to a position suitable for releasing the film coil, the second swing driving mechanism 632 is controlled to act, the second coil clamping piece 62 is driven to swing downwards, and the clamping of the film coil is released, so that the film coil can be released.

In the foregoing embodiments, the film roll is released from the film roll mechanism 5 by the roll take-up mechanism 6 being lifted. The lifting and lowering of the winding mechanism 6 may be synchronized or unsynchronized with the film breaking device 3. When the winding mechanism 6 and the film breaking device 3 are lifted synchronously, the winding mechanism 6 and the film breaking device 3 can be lifted by the same lifting driving mechanism, so that the structure is simplified. When the film taking-out mechanism 6 and the film breaking device 3 are not synchronous to lift, the film breaking device 3 and the film taking-out mechanism 6 can be relatively independent, and film breaking and film taking-out actions can be simultaneously carried out, so that the film breaking device 3 can break the next packaging film 40 in the process of taking down the previous film roll by the film taking-out mechanism 6, and further, the running beat is effectively accelerated, and the efficiency is improved.

To facilitate the take-up mechanism 6 to perform the take-up scroll operation, referring to fig. 14 and 15, in some embodiments, the film removing apparatus 10 includes a take-up scroll extension driving mechanism 64, the take-up scroll extension driving mechanism 64 being drivingly connected to the take-up mechanism 6 and driving the take-up scroll mechanism 6 to extend or retract in the first direction W with respect to the frame 1 to bring the take-up scroll mechanism 6 closer to and farther from the film winding mechanism 5. Therefore, the coil taking mechanism 6 can automatically approach or depart from the film rolling mechanism 5 under the driving of the coil taking telescopic driving mechanism 64, so that different requirements in the coil taking process and before and after coil taking can be flexibly and conveniently met, and the efficiency is improved.

The film roll taken down by the roll taking-up mechanism 6 can be collected by the collecting piece 9, so that the space occupation is further reduced, and the film roll can be conveniently and uniformly processed later.

In the case of collecting a film roll with the collecting member 9, the film roll may be manually or automatically put into the collecting member 9. For example, in some embodiments, the take-up mechanism 6 is configured not only to remove a film roll from the film roll mechanism 5, but also to put the film roll removed from the film roll mechanism 5 in the collecting member 9 to collect the film roll by the collecting member 9. Under the condition, the film roll taking mechanism 6 integrates the roll taking and unreeling functions, can automatically take down the film roll from the film roll taking mechanism 5, and can automatically put the taken film roll into the collecting piece 9, so that the functions are richer, and the efficiency is higher.

To facilitate the placement of the film roll into the collecting member 9 by the take-up mechanism 6, referring to fig. 7 and 14 and 15, in some embodiments, the film removal apparatus 10 includes a rotational drive mechanism 65, the rotational drive mechanism 65 being drivingly connected to the take-up mechanism 6 and driving the take-up mechanism 6 to rotate so as to rotate the take-up mechanism 6 to a position to place the film roll into the collecting member 9. Based on this, the film take-up mechanism 6 can be rotated from a position directly above the film unwinding mechanism 5 to an orientation that facilitates the placement of the film roll into the collecting member 9 by the rotation driving mechanism 65.

As described above, the film roll may need to be lifted and rotated by the roll-taking mechanism 6. In order to prevent the film roll from accidentally falling off the roll-taking mechanism 6 during the operation of the roll-taking mechanism 6, and to affect the smooth implementation of the function, referring to fig. 14, in some embodiments, the film removing apparatus 10 includes a third in-place detecting device 66, where the third in-place detecting device 66 detects whether the film roll is located on the roll-taking mechanism 6. Therefore, whether the film roll accidentally breaks away from the roll taking mechanism 6 can be timely found, the film roll is effectively ensured to be kept on the roll taking mechanism 6 in the whole action process after the roll taking mechanism 6 is jointed with the film roll, and further the roll taking mechanism 6 is convenient to drive the film roll to lift, rotate and the like, and the roll taking and unreeling functions are smoothly realized.

Here, as an example of the third in-place detecting device 66, referring to fig. 14, the third in-place detecting device 66 includes a third photosensor 661. After the packaging film 40 is wound into a film roll, the film roll is no longer transparent, so that the third photoelectric sensor 661 can smoothly detect whether the film roll is in place or not, and the packaging film roll is simple in structure, low in cost and high in accuracy.

The membrane removal system 100 and membrane removal apparatus 10 of the present application will be further described with reference to the embodiments shown in fig. 1-15.

As shown in fig. 1 to 3, in this embodiment, the film removal system 100 includes a conveying apparatus 20 and a film removal apparatus 10 that are arranged opposite in a first direction W (specifically, a left-right direction in fig. 1). The conveyor apparatus 20 is used to convey stacks 30 with non-integral packaging film 40. The film removal apparatus 10 is used to remove and collect non-integral packaging film 40 from the stack 30 on the conveyor apparatus 20. In this embodiment, the first direction W is perpendicular to the up-down direction H and the conveying direction of the conveying apparatus 20.

The conveying device 20 may employ various conveying mechanisms such as a conveying chain and a conveying belt, as long as the stack 30 can be conveyed. Accordingly, the structure of the conveying apparatus 20 will not be described again here, and the structure of the film removing apparatus 10 will be described with emphasis.

As shown in fig. 1 to 15, in this embodiment, the film removing apparatus 10 includes a frame 1, a lift frame 13, a guide rail 14, a lift driving mechanism 15, a lift limit 16, a height detecting device 2, a film breaking device 3, a film removing device 4, a film winding mechanism 5, a take-up mechanism 6, a frame 71, an air blowing device 72, a stopper 73, and a collecting member 9.

Wherein the frame 1 is used for supporting other components and providing a mounting foundation for the other components. As shown in fig. 1 and 2, in this embodiment, the rack 1 is located on one side (specifically, the left side in fig. 1) of the conveying apparatus 20 in the first direction W. Also, as shown in fig. 2, in this embodiment, the bottom of the frame 1 is provided with a footcup 11 and a press block 12. The height of the foot cup 11 is adjustable, so that the height of the stand 1 is adjustable. The pressing block 12 is arranged above the foot cup 11 to limit the foot cup 11.

The lifting frame 13 is arranged on the frame 1 and is used for supporting the height detection device 2, the film breaking device 3, the film removing device 4, the winding mechanism 6, the frame 71, the air blowing device 72 and the stop piece 73, and realizing synchronous lifting of the height detection device 2, the film breaking device 3, the film removing device 4, the winding mechanism 6, the frame 71, the air blowing device 72 and the stop piece 73. As shown in fig. 1 and 2, in this embodiment, the lifting frame 13 is connected to the frame 1 through a vertically extending guide rail 14, so that the lifting frame 13 can lift relative to the frame 1, so as to realize lifting arrangement of the lifting frame 13 on the frame 1, and further facilitate the lifting frame 13 to drive the height detecting device 2, the film breaking device 3, the film removing device 4, the winding mechanism 6, the frame 71, the air blowing device 72 and the stop member 73 to lift synchronously. Also, as shown in fig. 1, in this embodiment, the hoist 13 is provided with a wire drag chain 85 and a wire clip 84. The wiring drag chain 85 is used to drag the cables of the film removing apparatus 10 (e.g., the wires required by the motor, the signal wires required by the sensor, and the pipes required by the drive cylinder) to accommodate the expansion and contraction of the cables during the operation of the respective mechanisms. The wire clamping block 84 is used for being clamped with the cable of the film removing device 10 so as to limit the cable of the film removing device 10 and prevent wire disorder.

The lifting driving mechanism 15 is arranged on the frame 1 and is in driving connection with the lifting frame 13 so as to drive the height detecting device 2, the film breaking device 3, the film removing device 4, the coil taking mechanism 6, the frame 71, the blowing device 72 and the stop member 73 which are positioned on the lifting frame 13 to synchronously lift by driving the lifting frame 13 to lift. As shown in fig. 1 to 3, in this embodiment, the elevation drive mechanism 15 includes an elevation motor 152 and a chain transmission mechanism 151. The lifting motor 152 is in driving connection with the lifting frame 13 through the chain transmission mechanism 151 to drive the lifting frame 13 to lift.

The lifting limit 16 (see fig. 2) is disposed on the frame 1, and is used for limiting the lifting displacement of the lifting frame 13, so as to limit the lifting displacement of the height detection device 2, the film breaking device 3, the film removing device 4, the winding mechanism 6, the frame 71, the blowing device 72 and the stop member 73.

The height detecting device 2, the film breaking device 3, the film removing device 4, the winding mechanism 6, the frame 71, the blowing device 72 and the stop member 73 are all arranged on the lifting frame 13, and form a lifting assembly together with the lifting frame 13, and are lifted and lowered together under the driving of the lifting driving mechanism 15.

Wherein, the height detecting device 2 is used for detecting the height position of the packaging film 40, so that the film breaking device 3 and the film removing device 4 can break and remove the packaging film 40 at different height positions conveniently. As shown in fig. 1, in this embodiment, the height detecting device 2 includes a first detecting member 21, a second detecting member 22, and an auxiliary light source 23. The first detecting element 21 is configured to detect the height of the stack 30, and is disposed on the frame 71 and includes a first photoelectric sensor 211, where the first photoelectric sensor 211 is an opposite-type photoelectric sensor, and the emitting portion and the receiving portion of the first photoelectric sensor are disposed on opposite sides of the frame 71, so that when the stack 30 passes through the frame 71, light emitted by the first photoelectric sensor 211 can be blocked, thereby detecting the stack 30 and determining the height of the stack 30. The second detecting member 22 is used for detecting the height position of the packaging film 40 after the first photosensor 211 detects the height of the stack 30. As shown in fig. 1, in this embodiment, the second detecting member 22 is a color scale sensor 221, which detects in a preset height range (corresponding to a preset packaging film range) below the top surface of the stack 30, and detects the packaging film 40 according to the difference of the reflection degree of the packaging film 40 and the stack 30, so as to accurately determine the height position of the packaging film 40. As can be seen from fig. 1, in this embodiment, the color mark sensor 221 is disposed on the film breaking device 3, so that the color mark sensor 221 can be lifted together with the film breaking device 3, and can also move along the first direction W together with the film breaking device 3, and approach and separate from the packaging film 40, so that the color mark sensor 221 can conveniently move to a position suitable for detection along the first direction W before detection. The auxiliary light source 23 is used to provide auxiliary illumination for the color scale sensor 221 so that the color scale sensor 221 can reliably detect even in the case of insufficient natural illumination.

Perpendicular to the second direction L, both the first direction W and the up-down direction H, in particular the front-back direction in fig. 1, is parallel to the conveying direction of the conveying apparatus 20.

The film breaking device 3 is used for breaking the packaging film 40 on the stack 30 so as to facilitate the separation of the packaging film 40 from the stack 30. As shown in fig. 10 and 11, in this embodiment, the film breaking device 3 includes a mount 33, a heating wire 311, and a film breaking expansion driving cylinder 321.

The heating wire 311 is provided on the mounting base 33 and serves as the film breaking member 31 for heating and fusing the packaging film 40 to break the packaging film 40. The film breaking telescopic driving cylinder 321 is also arranged on the mounting seat 33 and is used as the film breaking telescopic driving mechanism 32, and is in driving connection with the electric heating wire 311, so that the electric heating wire 311 is driven to extend or retract along the first direction W, and the electric heating wire 311 can be close to and far away from the packaging film 40, so that the packaging film 40 can be fused by the electric heating wire 311 when needed.

The film removing device 4 is used for separating the packaging film 40 from the stack 30 before and after the packaging film 40 is broken by the film breaking device 3, so that the packaging film 40 is conveniently fused by the film breaking device 3, and the broken packaging film 40 is removed. As shown in fig. 1-6, in this embodiment, the film removing apparatus 10 includes two film removing devices 4, which are spaced apart along the second direction L and are located on the same side of the film breaking device 3 along the second direction L, so that, as shown in fig. 2, the two film removing devices 4 can be engaged with the packaging film 40 at two positions a and B, and the film breaking device 3 can break the packaging film 40 at a position C on the side of the position a remote from the position B outside the two film removing devices 4, so that a portion of the packaging film 40 located intermediate the position a and the position B can remain in a straightened state after breaking the packaging film 40, facilitating the subsequent placement of the packaging film 40 between the first roll bar 511 and the second roll bar 512 of the film rolling mechanism 5 by the two film removing devices 4.

Further, as shown in fig. 10 and 11, in this embodiment, the two film removing devices 4 are identical in structure, and each includes a film removing mechanism 41, a film removing expansion and contraction driving mechanism 42, and a first in-place detecting device 43. Wherein, the film removing mechanism 41 comprises a film sucking device 411, a vacuum generator 414 and an adsorption limit 415, and the film sucking device 411 comprises a sucker seat 412 and a sucker 413. The suction cup seat 412 is disposed on the lifting frame 13 to realize connection of the film removing device 4 and the lifting frame 13, so that the film removing device 4 can lift along with the lifting frame 13. The suction cup 413, the vacuum generator 414 and the suction limit 415 are all arranged on the suction cup seat 412. The suction cup 413 is used to suck the packaging film 40. In this embodiment, the suction cup holder 412 is provided with a plurality of suction cups 413 so that the same film removing device 4 can suction the packaging film 40 at a plurality of positions. The vacuum generator 414 is in gas communication with the suction cup 413, and vacuums the suction cup 413 so that the suction cup 413 can suction the packaging film 40 under negative pressure. The suction cup 413 is limited by the suction limit 415. The film removing telescopic driving mechanism 42 is arranged on the sucker seat 412 and comprises a film removing telescopic driving cylinder 421, the film removing telescopic driving cylinder 421 is in driving connection with the film removing mechanism 41, and the film removing mechanism 41 can be driven to move along the first direction W to approach or separate from the packaging film 40 so as to conveniently adsorb the packaging film 40 after approaching and pull the packaging film 40 from the stack 30 when separating. The first in-place detecting device 43 is disposed on the suction cup base 412, and includes an ultrasonic sensor 431 and a pressure sensor 432. After the suction cup 413 sucks the packaging film 40, the ultrasonic sensor 431 transmits ultrasonic waves to the packaging film 40, and the pressure sensor 432 detects the pressure of the suction cup 413, so that double detection of the packaging film 40 is realized, whether the packaging film 40 is kept on the film suction device 411 is judged, and the packaging film 40 is prevented from falling accidentally in the action process of the film suction device 411.

In this embodiment, the film removing device 4 not only pulls up the packaging film 40 from the stack 30 before the packaging film 40 is broken, facilitates the film breaking device 3 to break the packaging film 40, and removes the packaging film 40 from the stack 30 after the packaging film 40 is broken, but also feeds the removed packaging film 40 to the film winding mechanism 5, and winds the packaging film 40 into a film roll by the film winding mechanism 5. The corresponding removal of the packaging film 40 from the stack 30 and feeding it onto the film winding mechanism 5 is effected by the lowering action of the film removing device 4.

In the process that the film removing device 4 descends to send the packaging film 40 to the film rolling mechanism 5, the blowing device 72 is used for blowing to prevent the packaging film 40 from being hung on the stack 30, so that the film removing device 4 can conveniently and smoothly take down the packaging film 40 from the stack 30 and send the packaging film to the film rolling mechanism 5. As shown in fig. 1 to 3, in this embodiment, the blowing device 72 includes a plurality of blowing modules each provided on the frame 71 connected to the elevation frame 13 and arranged at intervals along the circumference of the frame 71. The frame 71 is square and hollowed out in the middle so that the stack 30 can pass through. Each blowing component has the same structure and comprises an air tap 721 and a connector 722, the air tap 721 is connected with an air source through the connector 722 so as to blow air to the packaging film 40, and the packaging film 40 is conveniently and smoothly taken down from the stack 30 by the film removing device 4 and is sent to the film rolling mechanism 5.

The film winding mechanism 5 is disposed on the frame 1 and below the film removing device 4, and is configured to wind the broken packaging film 40 into a film roll. Referring to fig. 12 and 13, and in combination with fig. 1 and 2, in this embodiment, the film winding mechanism 5 includes a winding mechanism 51, a winding driving mechanism 52, and a guard 53. The winding mechanism 51 includes a first winding lever 511 and a second winding lever 512. The first winding rod 511 and the second winding rod 512 are arranged at intervals along the first direction W, so that an accommodating space 513 is formed between the first winding rod 511 and the second winding rod 512, and the first winding rod 511 and the second winding rod 512 are located between the two film removing devices 4 along the second direction L, so that after the two film removing devices 4 that adsorb the broken packaging film 40 are directly lowered, the part of the packaging film 40 located between the two film removing devices 4 can be placed in the accommodating space 513. The first winding lever 511 and the second winding lever 512 are rotatably provided and are drivingly connected to the winding drive mechanism 52 to rotate under the drive of the winding drive mechanism 52, and wind the packaging film 40 interposed therebetween into a film roll. Wherein, the winding driving mechanism 52 is disposed below the winding mechanism 51 and includes a winding motor 521 to drive the first winding lever 511 and the second winding lever 512 to rotate when the winding motor 521 rotates. The guard 53 is configured as a hood, which covers the winding drive 52 with its opening facing downwards. The first winding rod 511 and the second winding rod 512 pass through the guard 53 from bottom to top, so that the lower ends of the first winding rod 511 and the second winding rod 512 are located below the guard 53 and are in driving connection with the winding motor 521, and the upper ends of the first winding rod 511 and the second winding rod 512 extend above the guard 53 and are exposed. Thus, the protection piece 53 can play a certain protection role on the winding driving mechanism 52 and play a certain supporting role on the packaging film 40 in the film winding process, in addition, in the winding process, the protection piece 53 can stop the packaging film 40 from the lower part, so that the packaging film 40 is prevented from winding into the winding driving mechanism 52, the winding process is convenient and smooth, the efficiency is improved, the damage of the winding driving mechanism 52 due to the winding into the packaging film 40 is avoided, and the structural reliability is improved.

In order to further prevent the packaging film 40 from falling off the winding mechanism 51 during the winding process, as shown in fig. 1-4, in this embodiment, the frame 71 is further provided with a stopper 73, the stopper 73 is initially located directly above the winding mechanism 51, and the middle of the stopper 73 is hollowed out to form a through hole 731, so that when the stopper 73 is lowered to the height position of the winding mechanism 51 along with the frame 71, the first winding rod 511 and the second winding rod 512 of the winding mechanism 51 can pass through the through hole 731 of the stopper 73, so that the stopper 73 can be pressed above the packaging film 40 placed between the first winding rod 511 and the second winding rod 512, and the packaging film 40 is stopped from above, so that the stopper 73 can prevent the packaging film 40 from falling off the first winding rod 511 and the second winding rod 512 from above, and the winding process can be conveniently and smoothly performed.

Since the shielding member 53 and the stopper 73 can stop the packaging film 40 from both upper and lower sides, the packaging film 40 can be more reliably prevented from coming off the winding mechanism 51 during winding.

As can be seen from fig. 12 and 13, in this embodiment, the protection member 53 is provided with a second in-place detecting device 54, the second in-place detecting device 54 includes a second photoelectric sensor 541, the emitting portion and the receiving portion of the second photoelectric sensor 541 are located on both sides of the first winding rod 511 and the second winding rod 512 along the second direction L, and the emitted light can pass through the accommodating space 513 between the first winding rod 511 and the second winding rod 512. Thus, when the film roll is located in the accommodating space 513, the light of the second photoelectric sensor 541 is blocked, the receiving portion of the second photoelectric sensor 541 cannot receive the light, and when the film roll is not located in the accommodating space 513, the light of the second photoelectric sensor 541 is not blocked, so that the receiving portion of the second photoelectric sensor 541 can receive the light, and the second photoelectric sensor 541 can determine whether the film roll is located on the winding mechanism 51 according to whether the receiving portion of the second photoelectric sensor 541 receives the light, so as to determine whether the film roll is separated from the winding mechanism 51, so that the winding mechanism 6 can conveniently perform the winding operation when the film roll is not separated.

The film roll taking-off mechanism 6 is used for taking off the film roll from the film roll-off mechanism 5 and placing the film roll into the collecting piece 9 for collection. As shown in fig. 1 to 7, in this embodiment, the coil taking mechanism 6 is disposed on the lifting frame 13, so that the coil taking mechanism 6 can be lifted and lowered together with the height detecting device 2, the film breaking device 3 and the film removing device 4 synchronously, and the coil taking mechanism 6 can be conveniently lowered to the coil taking height position to take coils when the coils are required to be taken. In addition, in the second direction L, the winding mechanism 6 is located between the two film removing devices 4, and corresponds to the position of the film winding mechanism 5 in the second direction L, so that after the winding mechanism 6 descends, the winding mechanism 6 can be aligned with the film winding mechanism 5 in the second direction L, and winding is convenient.

Fig. 14 and 15 further show the structure of the reel-up mechanism 6. As shown in fig. 14 and 15, in this embodiment, the reel-up mechanism 6 includes a base 69, a first reel holder 61, a second reel holder 62, and a swing drive mechanism 63. The swing drive mechanism 63 includes a first swing drive mechanism 631 and a second swing drive mechanism 632. The base 69 is connected with the lifting frame 13 to realize the arrangement of the coil taking mechanism 6 on the lifting frame 13, so that the coil taking mechanism 6 can be lifted together with the lifting frame 13. The first and second winding members 61 and 62 are respectively disposed at upper and lower ends of the base 69, and are vertically opposite to each other, and are each swingable up and down with respect to the base 69. The first swing driving mechanism 631 and the second swing driving mechanism 632 are driving cylinders, and are respectively in driving connection with the first curl member 61 and the second curl member 62 to respectively drive the first curl member 61 and the second curl member 62 to swing between a horizontal position and a swing position below the respective horizontal positions. Thus, the film roll can be clamped or released by controlling the swing of the first and second clamping members 61 and 62. Specifically, when the roll is required to be taken out, the second roll clamping member 62 is positioned below the film roll, the first roll clamping member 61 is positioned above the film roll, and the first roll clamping member 61 swings downward, so that the film roll can be clamped together with the second roll clamping member 62. When the film roll needs to be unreeled, the first roll clamping piece 61 is kept at the swinging position, the second roll clamping piece 62 swings downwards, the clamping action on the film roll is released, and the film roll can drop downwards and separate from the roll-taking mechanism 6.

As can be seen from fig. 14 and 15, in this embodiment, the first clamping member 61 and the second clamping member 62 each include a plurality of clamping bars 611 arranged at intervals along the second direction L, and the clamping bars 611 of the first clamping member 61 and the second clamping member 62 are opposite to each other vertically in one-to-one correspondence, so that after the first clamping member 61 swings downward, each clamping bar 611 of the first clamping member 61 and each clamping bar 611 of the second clamping member 62 clamp a film roll in one-to-one correspondence, thereby realizing reliable engagement with the film roll, facilitating the film roll taking-away by the take-up mechanism 6, and effectively preventing the film roll from falling during the transfer process. Moreover, as shown in fig. 13, corresponding to the plurality of winding rods 611 of the second winding member 62, the protecting member 53 of the film winding mechanism 5 is provided with a plurality of grooves 531, and the grooves 531 on the protecting member 53 correspond to the winding rods 611 of the second winding member 62 one by one, so that when the winding is required, each winding rod 611 of the second winding member 62 can extend into the corresponding groove 531 to hold the film roll. The groove 531 is recessed downward, the top is open, and two ends along the first direction W are open, so that after the second roll clamping member 62 is lowered in place, the roll clamping rod 611 of the second roll clamping member 62 can move along the first direction W to enter and exit the groove 531, and the first roll clamping member 61 and the second roll clamping member 62 move upward, so that the clamped film roll can be separated from the roll film mechanism 5, and the roll taking purpose is realized.

In order to automatically approach or separate the film taking-up mechanism 6 from the film taking-up mechanism 5 in the first direction W, as shown in fig. 14 and 15, in this embodiment, the film removing apparatus 10 includes a take-up expansion driving mechanism 64, the take-up expansion driving mechanism 64 is provided on a base 69, and includes a take-up expansion driving cylinder 641, the take-up expansion driving cylinder 641 extends in the first direction W and is drivingly connected to the first and second film clamps 61 and 62 through the base 69, so that the first and second film clamps 61 and 62 can be driven to move in the first direction W when the take-up expansion driving cylinder 641 expands and contracts, and thereby approach and separate from the film taking-up mechanism 5 in the first direction W.

In operation, after the first roll rod 511 and the second roll rod 512 wind the packaging film 40 into a film roll, the roll taking mechanism 6 descends to a roll taking height suitable for roll taking, the roll taking telescopic driving cylinder 641 stretches out, the roll taking rod 611 of the second roll clamping member 62 stretches into the groove 531, the film roll is supported from below, at this time, the first roll clamping member 61 is located above the film roll, in this case, the first swing driving mechanism 631 drives the first roll clamping member 61 to swing downwards, so that the first roll clamping member 61 clamps the film roll together with the second roll clamping member 62, then the roll taking mechanism 6 moves upwards, moves the film roll to above the first roll rod 511 and the second roll rod 512, separates the film roll from the film roll mechanism 5, and then the roll taking telescopic driving cylinder 641 retracts, so that the roll taking mechanism and the film roll clamped by the roll taking mechanism are not located right above the film roll mechanism 5 any more, but are staggered with the film roll mechanism 5 in the first direction W, and the roll taking mechanism 6 is convenient to move to an unreeling position suitable for releasing the film roll.

In this embodiment the unreeling position, suitable for releasing the film roll, is located directly above the collecting member 9. In this embodiment, the collecting member 9 is located on the side of the frame 1 remote from the conveying device 20, which is open at the top, as shown in fig. 1-3, to facilitate the falling-in of the film roll for the purpose of collecting the film roll.

When the take-up stretch driving cylinder 641 is retracted in the first direction W, the first and second pinching members 61 and 62 of the take-up mechanism 6 are still facing the side of the transporting apparatus 20, and in order to change the first and second pinching members 61 and 62 to the side of the collecting member 9, the first and second pinching members 61 and 62 are facilitated to throw the film roll into the collecting member 9, as shown in fig. 14 and 15, and in this embodiment, the film removing apparatus 10 further includes a rotation driving mechanism 65. The rotation driving mechanism 65 is provided on the base 69, and includes a rotation driving cylinder 651, a rotation shaft 652, and a swivel bearing 653. The rotation shaft 652 extends vertically and is rotatably connected to the base 69 through a swivel bearing 653. The rotation driving cylinder 651 extends in the first direction W and is in driving connection with the reel-up mechanism 6 to drive the reel-up mechanism 6 to rotate about the rotation shaft 652, so that the reel-up mechanism 6 can rotate in the horizontal plane and thus from a position toward the conveying apparatus 20 side to a position toward the collecting member 9 side.

After the roll taking mechanism 6 rotates to a position where the first roll clamping member 61 and the second roll clamping member 62 face the collecting member 9, the roll taking telescopic driving cylinder 641 can be extended again, so that the first roll clamping member 61 and the second roll clamping member 62 move to a position where the film roll is located right above the collecting member 9 along the first direction W, then the second swing driving mechanism 632 acts, the second roll clamping member 62 is driven to swing downwards, the film roll is released, and then the film roll can fall into the collecting member 9 under the action of gravity and is collected by the collecting member 9.

It can be seen that in this embodiment, the unreeling mechanism 6 can smoothly complete the unreeling and unreeling processes by performing the movement in the first direction W, the movement in the up-down direction H, and the rotational movement about the vertical axis.

In order to prevent the film roll from falling off during the operation of the roll-taking-up mechanism 6, as shown in fig. 14, in this embodiment, a third in-place detecting device 66 is further provided on the base 69, and the third in-place detecting device 66 includes a third photoelectric sensor 661, specifically a diffuse reflection photoelectric sensor, which detects whether the film roll is located on the roll-taking-up mechanism 6 by emitting light to the film roll, so as to prevent the film roll from falling off during the operation of the roll-taking-up mechanism 6.

Meanwhile, as shown in fig. 14 and 15, in this embodiment, a wire pipe 67 and a take-up drag chain 68 are further provided on the base 69 for the wire to pass through and drag the wire to move, respectively.

In this embodiment, each of the driving cylinders (for example, the film breaking stretch driving cylinder 321, the film removing stretch driving cylinder 421, the first swing driving mechanism 631, the second swing driving mechanism 632, the roll taking stretch driving cylinder 641, and the rotation driving cylinder 651) is an air cylinder. As shown in fig. 1, to control the orderly action of these cylinders, in this embodiment the membrane removal apparatus 10 further comprises a pneumatic valve island 82 and a pneumatic triplet 81. All the cylinders are connected with a gas source through a pneumatic valve island 82 and a pneumatic triplet 81 which are arranged on the frame 1. Solenoid valves are provided on the pneumatic valve islands 82 to control the opening and closing of the respective air paths. The pneumatic triple piece 81 is connected with the pneumatic valve island 82 and the air source, and plays roles in pressure regulation, filtration and lubrication. Also, in this embodiment, a pressure regulating gauge 83 is further provided on the frame 1 to perform air pressure regulation.

With the structural form of the embodiment, the film removing device 10 can adapt to the removal of the packaging film 40 with multiple specifications and different positions, and the packaging film 40 is wound and collected, so that the space is saved.

Before the stack 30 moves in place on the conveying device 20, the lifting assembly is at a high position, after the stack 30 is in place, the lifting assembly descends, in the descending process, the first detecting piece 21 detects the stack height, and after the stack height is detected, the second detecting piece 22 detects the position of the packaging film according to the preset packaging film range, and the accurate packaging film position is determined; after the position of the packaging film 40 is determined, firstly, the film sucking device 411 stretches out to suck the packaging film 40, then the heating wire 311 stretches out, the film is ready to be fused, the film sucking device 411 pulls back, the packaging film 40 is pulled up from the stack 30, and the packaging film 40 is fused by the heating wire 311; after that, the film suction device 411 continues to suck the broken packaging film 40 and descends onto the film winding mechanism 5, places the broken packaging film 40 on the film winding mechanism 5, and winds the film roll by the film winding mechanism 5; after the winding is completed, the winding mechanism 6 performs winding and puts it into the collecting member 9.
