Among them, as shown in Figure 1, the packaging material roll 100 is supported on the packaging material roll transfer trolley 41, and two sets of film tearing mechanisms 421 are respectively arranged at opposite ends of the packaging material roll 100. The two sets of film tearing mechanisms 421 cooperate with each other and move to the two ends of the center hole of the packaging material roll 100 respectively to tear off the protective film on the wall of the center hole of the packaging material roll 100.

After the protective film at the center hole of the packaging material roll 100 is torn off, the rotating shaft module 1 is inserted into the center hole of the packaging material roll 100 by the packaging material roll threading device 43. The rotating shaft module 1 is placed in a fixed storage area, and the transfer robot 431 is arranged between the storage area of the rotating shaft module 1 and the threading station of the packaging material roll 100 to pick up the rotating shaft module 1 and thread the rotating shaft module 1 into the center hole of the packaging material roll 100. Therefore, after the threading of the packaging material roll 100 is completed, the opposite ends of the rotating shaft module 1 can be picked up by the handling tool to transfer the packaging material roll 100 to the next station without contacting the packaging material roll 100, so as to ensure the integrity and aesthetics of the packaging material roll 100.

The utility model provides a packaging material roll threading device 4, comprising: a packaging material roll transfer trolley 41, a packaging material roll film tearing device 42 and a packaging material roll threading device 43, the packaging material roll transfer trolley 41 is used to support a vertically arranged packaging material roll 100, and to transport the packaging material roll 100 to one side of the packaging material roll threading device 43; when the packaging material roll 100 is located at the threading station, two sets of film tearing mechanisms 421 are arranged on opposite sides of the packaging material roll 100 along the axial direction of the packaging material roll 100, so as to tear off the protective film in the area where the central hole of the packaging material roll 100 is located; at the same time When the packaging material roll is being threaded, the transfer robot 431 of the packaging material roll threading device 43 can move to the storage area of the shaft module 1 to pick up the shaft module 1, and can thread the shaft module 1 into the center hole of the packaging material roll 100, so that other handling tools can lift the two ends of the shaft module 1 to transfer the packaging material roll 100 to the next workstation. There is no need to manually transport and thread the packaging material roll 100, which realizes the automation of the transfer of the packaging material roll 100, saves labor costs, and greatly improves the production efficiency of the entire packaging material preparation production line.

2 to 12 , the packaging material roll transfer trolley 41 , the packaging material roll film tearing device 42 , the packaging material roll shaft threading device 43 and the packaging material roll transfer device 44 provided by the present invention are described in detail.

2 and 3 , the packaging material roll transfer vehicle 41 includes a mobile platform 411 , a supporting seat 412 and a clamping mechanism 413 . The supporting seat 412 and the clamping mechanism 413 are respectively arranged on the mobile platform 411 , and the supporting seat 412 is used to support the packaging material roll 100 .

The clamping mechanism 413 includes a first clamping unit 4131 and a second clamping unit 4132. The first clamping unit 4131 and the second clamping unit 4132 are respectively disposed on two sides of the supporting seat 412, and clamp the packaging material roll 100 along the axial direction of the packaging material roll 100.

It is understandable that the packaging material roll 100 flipping device is used to flip the flat packaging material roll 100 to a vertical packaging material roll 100, so as to facilitate the threading of the packaging material roll 100. A packaging material roll transfer trolley 41 is arranged between the packaging material roll 100 flipping device and the packaging material roll threading device 43, so as to transfer the flipped packaging material roll 100 to the packaging material roll threading device 43 through the packaging material roll transfer trolley 41.

Specifically, as shown in FIG1 , the mobile platform 411 is disposed on the body of the packaging material roll transfer vehicle 41 and can reciprocate in the extension direction of the body. The support seat 412 is fixed to the top of the mobile platform 411 and is used to support the packaging material roll 100 so that the vertical packaging material roll 100 can follow the mobile platform 411 to transfer from the packaging material roll 100 turning device to the packaging material roll threading device 43. Among them, the clamping mechanism 413 is disposed on the top of the mobile platform 411. During the movement of the mobile platform 411, the packaging material roll 100 is clamped and fixed by the clamping mechanism 413 to prevent the packaging material roll 100 from falling off.

The utility model provides a packaging material roll transfer trolley 41, wherein a mobile platform 411 is configured to move between a packaging material roll 100 turning device and a packaging material roll shaft threading device 43, and the vertical packaging material roll 100 is transferred from the packaging material roll 100 turning device to the packaging material roll shaft threading device 43 for shaft threading through the mobile platform 411, and a supporting seat 412 and a clamping mechanism 413 are respectively arranged on the mobile platform 411, the supporting seat 412 is used for supporting the vertically arranged packaging material roll 100, and the clamping mechanism 413 is used for clamping and fixing the packaging material roll 100, thereby ensuring the stability of the packaging material roll 100 during movement and preventing the packaging material roll 100 from slipping; the packaging material roll 100 does not need to be manually transported, thereby realizing the automation of transferring the packaging material roll 100, saving labor costs, and improving the production efficiency of the entire packaging material preparation production line.

2 and 3 , the clamping mechanism 413 includes a first clamping unit 4131 and a second clamping unit 4132. The first clamping unit 4131 and the second clamping unit 4132 are disposed on both sides of the supporting seat 412 and clamp the packaging material roll 100 along its axial direction.

It is understandable that, as shown in FIG. 2 , the support seat 412 is disposed in the middle area of the top of the mobile platform 411. The first clamping unit 4131 and the second clamping unit 4132 are arranged side by side in a direction perpendicular to the movement of the mobile platform 411, and are disposed on opposite sides of the support seat 412. The bottom of the packaging material roll 100 is supported by the support seat 412. The opposite end surfaces of the packaging material roll 100 are respectively abutted against the first clamping unit 4131 and the second clamping unit 4132, so that the packaging material roll 100 is clamped and fixed along the axial direction of the packaging material roll 100 by the first clamping unit 4131 and the second clamping unit 4132.

3 , at least one of the first clamping unit 4131 and the second clamping unit 4132 includes: a fixed bracket 41311, a movable bracket 41312, a linear drive member 41313 and a clamping plate 41314. The fixed bracket 41311 is disposed on the movable platform 411, the movable bracket 41312 is movably disposed on the fixed bracket 41311 along the axial direction of the packaging material roll 100, at least part of the linear drive member 41313 is disposed on the fixed bracket 41311, and the clamping plate 41314 is disposed on a side of the movable bracket 41312 facing the supporting seat 412.

The linear driving member 41313 is used to drive the movable bracket 41312 to move relative to the fixed bracket 41311 , so that the movable bracket 41312 drives the clamping plate 41314 to contact or separate from the end surface of the packaging material roll 100 .

It is understandable that the specific structures of the first clamping unit 4131 and the second clamping unit 4132 can be the same. Taking the first clamping unit 4131 as an example, the first clamping unit 4131 includes a fixed bracket 41311, a movable bracket 41312 and a clamping plate 41314. As shown in FIG3 , the fixed bracket 41311 is fixed to the movable platform 411. The extension direction of the fixed bracket 41311 is parallel to the moving direction of the movable platform 411. The movable bracket 41312 is movably arranged on the fixed bracket 41311 and can move along the axial direction of the packaging material roll 100, that is, the moving direction of the movable bracket 41312 is perpendicular to the moving direction of the movable platform 411.

Further, as shown in FIG3 , the first clamping unit 4131 further includes a linear drive member 41313. A portion of the linear drive member 41313 is fixed to the fixed bracket 41311. The extension direction of the driving end of the linear drive member 41313 is arranged parallel to the axial direction of the packaging material roll 100. The driving end of the linear drive member 41313 is connected to the mobile bracket 41312 to drive the mobile bracket 41312 to move in a direction close to or away from the packaging material roll 100. The clamping plate 41314 is fixed to a side of the mobile bracket 41312 close to the supporting seat 412, and can move with the mobile bracket 41312 to clamp the end surface of the packaging material roll 100.

During the process of moving and threading the packaging material roll 100, the clamping plates 41314 of the first clamping unit 4131 and the clamping plates 41314 of the second clamping unit 4132 respectively move toward the direction close to the packaging material roll 100 to clamp the opposite end surfaces of the packaging material roll 100. When the packaging material roll 100 is threaded, the clamping plates 41314 of the first clamping unit 4131 and the clamping plates 41314 of the second clamping unit 4132 move away from each other to release the packaging material roll 100, thereby facilitating the transfer of the packaging material roll 100 to the next process.

Alternatively, one of the first clamping unit 4131 and the second clamping unit 4132 is fixed relative to the movable platform 411, and the clamping plate 41314 of the other one moves along the axial direction of the packaging material roll 100, so that the first clamping unit 4131 and the second clamping unit 4132 can also clamp and fix the packaging material roll 100.

In some embodiments, as shown in FIG3 , the linear drive member 41313 is a lead screw drive mechanism 4331. The output end of the lead screw motor is connected to the lead screw of the lead screw drive mechanism 4331, the lead screw nut of the lead screw drive mechanism 4331 is connected to the bottom end of the mobile bracket 41312, and the mobile bracket 41312 is connected to the clamping plate 41314. The lead screw motor drives the lead screw 42113 to rotate, and then the lead screw drives the lead screw nut to perform linear motion. The mobile bracket 41312 moves with the lead screw nut, and the clamping plate 41314 moves with the mobile bracket 41312, thereby driving the clamping plate 41314 to contact or separate from the end surface of the packaging material roll 100.

Further, as shown in FIG3 , in the packaging material winding and threading shaft device 4 provided by the present invention, at least one of the first clamping unit 4131 and the second clamping unit 4132 is provided with a driving component 414. The shaft module 1 includes a shaft 11, a driving gear 12 and an opening and closing mechanism 13.

The driving gear 12 is disposed at the end of the rotating shaft 11. The opening and closing mechanism 13 is disposed at the middle of the rotating shaft 11. The driving component 414 and the opening and closing mechanism 13 are connected by power coupling to drive the opening and closing mechanism 13 to switch between the locked state and the separated state.

When the opening and closing mechanism 13 is in a locked state, the opening and closing mechanism 13 abuts against the inner wall of the packaging material roll 100. When the opening and closing mechanism 13 is in a separated state, the opening and closing mechanism 13 is separated from the inner wall of the packaging material roll 100.

It is understandable that the shaft module 1 is used to pass through the center hole of the packaging material roll 100. The packaging material roll 100 is passed through the shaft so that the AGV transport vehicle 200 can clamp both ends of the shaft module 1, thereby realizing the transfer of the packaging material roll 100. The shaft 11 is passed through the center hole of the packaging material roll 100.

As shown in Fig. 3, the driving component 414 is provided on the clamping mechanism 413, and is used to drive the opening and closing mechanism 13 to switch between the locked state and the separated state. When the opening and closing mechanism 13 is in the locked state, the opening and closing mechanism 13 can lock the packaging material roll 100 to firmly fix the shaft module 1 in the center hole of the packaging material roll 100.

Specifically, as shown in Figures 4 and 5, the packaging material winding and threading shaft device 4 provided by the present invention, the driving component 414 includes a power motor 4141 and a control gear 4142. The opening and closing mechanism 13 includes a clutch gear 131, a clutch disk 132, a fixed disk and a plurality of locking members 134.

The output end of the power motor 4141 is connected to the control gear 4142. The clutch gear 131, the clutch disc 132 and the fixed disc are sequentially sleeved on the rotating shaft 11. The control gear 4142 is configured to be meshed with the clutch gear 131, and the clutch gear 131 and the clutch disc 132 are connected to drive the clutch disc 132 to rotate relative to the rotating shaft 11. The fixed disc is connected to the rotating shaft 11. A plurality of locking members 134 are circumferentially arranged on the fixed disc, and the clutch disc 132 is respectively connected to the transmission ends of the plurality of locking members 134. The clutch disc 132 can control the plurality of locking members 134 in linkage when rotating, so that the opening and closing mechanism 13 switches between a locked state and a separated state.

When the opening and closing mechanism 13 is in a locked state, the locking ends of each locking member 134 synchronously move away from the rotating shaft 11 to lock the packaging material roll 100; when the opening and closing mechanism 13 is in a separated state, the locking ends of each locking member 134 synchronously approach the rotating shaft 11 to release the locking restriction on the packaging material roll 100.

It is understandable that the clutch gear 131, the clutch plate 132 and the fixed plate are all provided with a central hole, so that the clutch gear 131, the clutch plate 132 and the fixed plate are coaxially arranged, and are sequentially sleeved on the peripheral wall of the rotating shaft 11. The clutch gear 131 and the clutch plate 132 are coaxially connected, and can be rotatably sleeved on the peripheral wall of the rotating shaft 11, so that when the clutch gear 131 receives a rotational driving force, the clutch gear 131 drives the clutch plate 132 to rotate relative to the rotating shaft 11; the fixed plate can be fixedly connected to the rotating shaft 11 by a key or a locking bolt.

At the same time, since the clutch disk 132 and the fixed disk are coaxially arranged, when the plurality of locking members 134 are arranged along the circumference of the fixed disk, each locking member 134 will also be arranged along the circumference of the clutch disk 132 .

Optionally, each locking member 134 can be movably arranged on the fixed disk, for example, the locking member 134 can be rotatably arranged on the fixed disk, or the locking member 134 can be movably arranged on the fixed disk along a specific linear direction. Optionally, the clutch disk 132 can be connected to the transmission ends of multiple locking members 134 respectively by means of hinged connection or contact connection. In this way, when the clutch disk 132 rotates relative to the rotating shaft 11, the clutch disk 132 can simultaneously apply a force to the transmission ends of each locking member 134, so that the locking ends of each locking member 134 are synchronously abutted or separated from the inner wall of the packaging material roll 100.

In actual application, the opening and closing mechanism 13 is sleeved on the peripheral wall of the rotating shaft 11, and is inserted into the central hole of the packaging material roll 100 together with the rotating shaft 11. The operator can apply driving force to the clutch gear 131 based on the rotation driving device, and the clutch gear 131 drives the clutch disk 132 to rotate, and then the clutch disk 132 controls the locking state between each locking member 134 and the packaging material roll 100.

When the locking ends of the multiple locking pieces 134 are separated from the inner wall of the packaging material roll 100, the distance between the locking ends of the multiple locking pieces 134 and the center of the fixed disk is less than or equal to the diameter of the fixed disk; when the locking ends of the multiple locking pieces 134 are abutted against the inner wall of the packaging material roll 100, the distance between the locking ends of the multiple locking pieces 134 and the center of the fixed disk is greater than the diameter of the fixed disk.

The diameter of the fixing disk is smaller than or equal to the inner diameter of the central hole of the packaging material roll 100 .

For the rotating shaft module 1 shown in this embodiment, by configuring the rotating shaft module 1 with a rotating shaft 11, a driving gear 12 and an opening and closing mechanism 13, after the entire rotating shaft module 1 is inserted into the central hole of the packaging material roll 100, the opening and closing mechanism 13 is controlled to switch between a locked state and a separated state to control the locking state of the packaging material roll 100 by the opening and closing mechanism 13, so as to conveniently control the rotating shaft 11 and the packaging material roll 100 to be combined into one or separated based on the opening and closing mechanism 13. This design facilitates supporting the rotating shaft 11 of the rotating shaft module 1 on a transfer device to transport the packaging material roll 100, thereby preventing the packaging material roll 100 from shaking relative to the rotating shaft 11 during transportation.

As can be seen from the above, the rotating shaft module 1 shown in the utility model is not only convenient for reliable transportation of the packaging material roll 100, but also convenient for driving the packaging material roll 100 to rotate, which facilitates the film tearing and label removal operations of the packaging material roll 100, and is beneficial to improving the production efficiency of the packaging material preparation production line.

In some embodiments, as shown in FIG. 5 , the clutch disc 132 is provided with a plurality of arc-shaped guide portions 1321 along the circumferential direction, and the plurality of arc-shaped guide portions 1321 and the plurality of locking members 134 are arranged opposite to each other.

At least part of the locking member 134 is movably arranged on the fixed disk, and the transmission end of the locking member 134 contacts the side wall of the arc-shaped guide portion 1321, and the locking end of the locking member 134 extends toward the inner wall of the packaging material roll 100; along the extension direction from the head end to the end of the arc-shaped guide portion 1321, the distance between the side wall of the arc-shaped guide portion 1321 and the rotating shaft 11 gradually increases, so that in the process of the transmission end of the locking member 134 moving from the head end to the end of the arc-shaped guide portion 1321 relative to the arc-shaped guide portion 1321, the transmission end of the locking member 134 gradually moves away from the position where the rotating shaft 11 is located.

Specifically, the clutch disk 132 can rotate between a first position and a second position relative to the rotating shaft 11 . The rotation state of the clutch disk 132 will be described below in conjunction with the moving state of the locking member 134 .

As shown in Figure 5, when the clutch disk 132 is in the first position, the transmission end of the locking member 134 contacts the side wall corresponding to the head end of the arc-shaped guide portion 1321; at this time, the side wall corresponding to the head end of the arc-shaped guide portion 1321 reaches the minimum distance relative to the rotating shaft 11, so that the distance between the locking end of the locking member 134 and the center of the fixed disk is less than or equal to the diameter of the fixed disk, so that the opening and closing mechanism 13 is in a separated state, and the locking ends of each locking member 134 are separated from the inner wall of the packaging material roll 100.

As shown in Figure 5, when the clutch disk 132 is in the second position, the transmission end of the locking member 134 contacts the side wall corresponding to the end of the arc-shaped guide portion 1321; at this time, the side wall corresponding to the head end of the arc-shaped guide portion 1321 reaches the maximum distance relative to the rotating shaft 11, so that the distance between the locking end of the locking member 134 and the center of the fixed disk is greater than the diameter of the fixed disk, so that the opening and closing mechanism 13 is in a locked state, and the locking ends of each locking member 134 abut against the inner wall of the packaging material roll 100.

In some embodiments, as shown in FIG. 1 and FIG. 3 , the rotating shaft module 1 further includes a positioning plate 14 ; the positioning plate 14 is connected to the rotating shaft 11 and is spaced apart from the opening and closing mechanism 13 .

When the opening and closing mechanism 13 is in a locked state, the locking ends of each locking member 134 on the opening and closing mechanism 13 abut against the first end of the packaging material roll 100; when the opening and closing mechanism 13 is in a separated state, the locking ends of each locking member 134 on the opening and closing mechanism 13 are separated from the first end of the packaging material roll 100; the positioning plate 14 is used to abut against the second end of the packaging material roll 100.

The opening and closing mechanism 13 and at least part of the positioning plate 14 are configured to penetrate the packaging material roll 100 , the opening and closing mechanism 13 abuts against or separates from the inner wall of the packaging material roll 100 , and the positioning plate 14 abuts against the end of the packaging material roll 100 along the axial direction.

It is understandable that the positioning plate 14 is located in the middle of the rotating shaft 11 , and the distance between the positioning plate 14 and the opening and closing mechanism 13 is adapted to the axial width of the packaging material roll 100 .

When the shaft module 1 is inserted into the central hole of the packaging material roll 100, one end of the shaft 11 provided with the opening and closing mechanism 13 is first inserted into the central hole of the packaging material roll 100. When the opening and closing mechanism 13 reaches the first end of the packaging material roll 100, the positioning plate 14 is at the second end of the packaging material roll 100. At this time, the opening and closing mechanism 13 is controlled to be in a locked state, so that the locking ends of the locking members 134 on the opening and closing mechanism 13 can abut against the first end of the packaging material roll 100. Since the positioning plate 14 abuts against the second end of the packaging material roll 100, while the axial insertion position of the shaft module 1 relative to the packaging material roll 100 is limited by the positioning plate 14, the packaging material roll 100 is also limited between the opening and closing mechanism 13 and the positioning plate 14, ensuring that the shaft module 1 and the packaging material roll 100 are combined into one.

Correspondingly, when the opening and closing mechanism 13 is controlled to be in a separated state, the locking ends of the locking members 134 on the opening and closing mechanism 13 no longer abut against the first end of the packaging material roll 100, and the shaft module 1 can be easily pulled out from the center hole of the packaging material roll 100.

It should be noted here that since the packaging material roll 100 usually includes a paper roll and a paper tube, the paper roll is sleeved on the outside of the paper tube, so that when the opening and closing mechanism 13 is in a locked state, the locking end of each locking member 134 abuts against one end of the paper tube axially, and the positioning plate 14 abuts against the other end of the paper tube axially.

In some embodiments, as shown in Figures 4 and 5, in order to ensure that a rotational driving force can be applied to the rotating shaft 11 on both sides of the packaging material roll 100, two driving gears 12 are provided. The two driving gears 12 are respectively arranged at both ends of the rotating shaft 11, and the opening and closing mechanism 13 and the positioning plate 14 are located between the two driving gears 12.

2 and 3 , the clamping mechanism 413 is further provided with a lifting mechanism 415. The lifting mechanism 415 and the driving component 414 are arranged opposite to each other, and the lifting mechanism 415 is used to control the lifting of the driving component 414 so as to make the control gear 4142 mesh with or separate from the clutch gear 131.

It is understandable that the driving component 414 includes a power motor 4141 and a control gear 4142. The output end of the power motor 4141 is connected to the control gear 4142 to drive the control gear 4142 to rotate. The lifting mechanism 415 is arranged on the first clamping unit 4131 or the second clamping unit 4132. Among them, the lifting mechanism 415 can be an electric push rod. The electric push rod is extended in the vertical direction. One end of the electric push rod is fixed on the clamping mechanism 413, and the other end is provided with a mounting plate. The power motor 4141 is fixed to the mounting plate.

The electric push rod drives the mounting plate to rise, so that the driving component 414 rises to a position close to the clutch gear 131, thereby realizing the meshing connection between the control gear 4142 and the clutch gear 131. At this time, when the clutch gear 131 receives the rotational driving force input by the control gear 4142, the control opening and closing mechanism 13 is switched from the separation state to the locking state, ensuring that the opening and closing mechanism 13 is in contact with the inner wall of the packaging material roll 100, thereby combining the rotating shaft module 1 and the packaging material roll 100 into one.

The electric push rod drives the mounting plate to descend so that the control gear 4142 is separated from the clutch gear 131. At this time, the packaging material assembly formed by the rotating shaft module 1 and the packaging material roll 100 can be transferred, and then the packaging material assembly can be transferred to the next workstation through the AGV transport vehicle 200 to perform film tearing and label removal operations on the packaging material roll 100.

In the case where both the first clamping unit 4131 and the second clamping unit 4132 include: a fixed bracket 41311 , a movable bracket 41312 , a linear drive member 41313 and a clamping plate 41314 , the lifting mechanism 415 may be disposed on the movable bracket 41312 .

As shown in FIG2 , the supporting seat 412 includes a first supporting plate 4121 and a second supporting plate 4122. The first supporting plate 4121 and the second supporting plate 4122 are respectively disposed on the movable platform 411. The first supporting plate 4121 and the second supporting plate 4122 form a "V"-shaped structure to support the bottom end of the packaging material roll 100.

It is understandable that the first supporting plate 4121 and the second supporting plate 4122 are both fixed on the top of the mobile platform 411. The first supporting plate 4121 and the second supporting plate 4122 can be configured to be set at an obtuse angle to form a "V"-shaped structure, which can adapt to the curvature of the bottom end of the packaging material roll 100 and prevent the packaging material roll 100 from rolling down; at the same time, the first supporting plate 4121 and the second supporting plate 4122 are set in a "V" shape so that the supporting seat 412 can support a variety of packaging material rolls 100 of different diameters and specifications, and has good versatility.

As shown in Figures 2 and 3, the mobile platform 411 is movably arranged on the support track 416. The support track 416 is extended between the packaging material turning device and the packaging material winding shaft device 43. The mobile platform 411 is equipped with a travel drive mechanism 4111. The travel drive mechanism 4111 is used to drive the mobile platform 411 to move along the extension direction of the support track 416.

It is understandable that there are two support rails 416. Correspondingly, two sliders are provided at opposite ends of the bottom of the mobile platform 411, and the two sliders are slidably provided on the two support rails 416 in a one-to-one correspondence. As shown in FIG. 2 , a travel drive mechanism 4111 is provided in the area between the two support rails 416, and the two sliders are driven by the travel drive mechanism 4111 to move along the two support rails 416 respectively.

Optionally, the walking drive mechanism 4111 can be a gear rack drive mechanism, which includes a gear portion and a rack portion, the gear portion and the rack portion are meshingly arranged, the gear portion is arranged on the mobile platform 411, and the rack portion is arranged on the ground and extends along the extension direction of the support rail 416.

As shown in Fig. 6 and Fig. 7, the packaging material winding and threading shaft device 4 provided by the present invention, the film tearing mechanism 421 includes a driving platform 4211, a first mechanical arm 4212 and a second mechanical arm 4213. The first mechanical arm 4212 and the second mechanical arm 4213 are respectively arranged on the driving platform 4211, and the driving platform 4211 is used to drive the first mechanical arm 4212 and the second mechanical arm 4213 to move toward or away from each other in a straight line direction.

When the film-tearing mechanism 421 is in the first film-tearing state, the execution ends 42121 of the first robot arm 4212 and the second robot arm 4213 are close to each other and connected to the protective film in the area where the central hole of the packaging material roll 100 is located.

When the film-tearing mechanism 421 is in the second film-tearing state, the execution ends 42121 of the first robot arm 4212 and the second robot arm 4213 move away from each other to tear off the protective film in the area where the central hole of the packaging material roll 100 is located.

It is understandable that before piercing the central hole of the packaging material roll 100, a manual or automatic piercing device can be used to tear off the protective film corresponding to the central hole of the packaging material roll 100. As shown in FIG6, the packaging material roll 100 is supported on the supporting seat 412, and two sets of film tearing mechanisms 421 are respectively arranged at opposite ends of the packaging material roll 100.

The extension direction of the driving platform 4211 is arranged parallel to the moving direction of the mobile platform 411. The first mechanical arm 4212 and the second mechanical arm 4213 are movably arranged on the driving platform 4211, and the driving platform 4211 drives the first mechanical arm 4212 and the second mechanical arm 4213 to move closer to or away from each other along the moving direction of the mobile platform 411.

When the film-tearing mechanism 421 is in the film-tearing state, the driving platform 4211 drives the first mechanical arm 4212 and the second mechanical arm 4213 to approach each other, so that the execution ends 42121 of the first mechanical arm 4212 and the second mechanical arm 4213 are moved to the center hole of the packaging material roll 100, so that the execution ends 42121 of the first mechanical arm 4212 and the second mechanical arm 4213 can hook the protective film; then, the driving platform 4211 drives the first mechanical arm 4212 and the second mechanical arm 4213 away from each other, so that the execution ends 42121 of the first mechanical arm 4212 and the second mechanical arm 4213 are connected to the protective film and separated from each other, so as to complete the film-tearing operation of the protective film in the area where the center hole is located. In this way, the film-tearing mechanism 421 automatically simulates the manual film-tearing operation, thereby improving the efficiency of film-tearing.

The utility model provides a packaging material roll film tearing device 42, two sets of film tearing mechanisms 421 are arranged on opposite sides of the packaging material roll 100 along the axial direction of the packaging material roll 100, a first mechanical arm 4212 and a second mechanical arm 4213 are respectively arranged on a driving platform 4211, and when the film tearing mechanism 421 is in a first film tearing state, the driving platform 4211 drives the first mechanical arm 4212 and the second mechanical arm 4213 to approach each other, so that the execution ends 42121 of the first mechanical arm 4212 and the second mechanical arm 4213 move to the position where the center hole of the packaging material roll 100 is located. area, and is connected to the protective film in the area where the center hole of the packaging material roll 100 is located; when the film tearing mechanism 421 is in the second film tearing state, the driving platform 4211 drives the execution ends 42121 of the first robot arm 4212 and the second robot arm 4213 to move away from each other, so as to tear off the protective film in the area where the center hole of the packaging material roll 100 is located. The two sets of film tearing mechanisms 421 cooperate with each other, and there is no need to rely on manual film tearing, thereby realizing automatic film tearing of the protective film in the area where the center hole of the packaging material roll 100 is located, which is convenient for the subsequent threading operation of the packaging material roll 100.

Specifically, as shown in FIG. 7 , the driving platform 4211 includes: a guide platform 42111 , a rotating motor 42112 , a driving screw 42113 , a first transfer seat 42114 and a second transfer seat 42115 .

The rotating motor 42112 is disposed on the guide platform 42111, and the driving screw 42113 is rotatably disposed on the guide platform 42111 and is power-coupled with the rotating motor 42112. The driving screw 42113 includes a first screw segment 42100 and a second screw segment 42200, and the threads of the first screw segment 42100 and the second screw segment 42200 have opposite rotation directions.

The first transfer seat 42114 and the second transfer seat 42115 are movably disposed on the guide platform 42111 along the axial direction of the driving screw 42113. The first transfer seat 42114 is threadedly connected to the first screw segment 42100, and the second transfer seat 42115 is threadedly connected to the second screw segment 42200.

The first mechanical arm 4212 is disposed on the first transfer seat 42114 , the second mechanical arm 4213 is disposed on the second transfer seat 42115 , and the axial direction of the driving screw 42113 is parallel to the end surface of the packaging material roll 100 .

It is understandable that, as shown in FIG. 6 and FIG. 7 , the guide stand 42111 is fixed on a stand on one side of the packaging material roll transfer trolley 41 .

In some embodiments, the rotating motor 42112 is fixed on the guide platform 42111, and the driving screw 42113 is rotatably arranged on the guide platform 42111. The screw has a first screw segment 42100 and a second screw segment 42200 with opposite thread directions. The first transfer seat 42114 is sleeved on the first screw segment 42100 and is threadedly connected to the first screw segment 42100; the second transfer seat 42115 is sleeved on the second screw segment 42200 and is threadedly connected to the second screw segment 42200.

In some embodiments, as shown in FIG. 6 , the guide frame 42111 is in a rectangular frame structure, and the driving screw 42113 is disposed on the inner side of the guide frame 42111 and extends along the length direction of the guide frame 42111 .

The first transfer seat 42114 and the second transfer seat 42115 are respectively movably arranged on the guide frame 42111 along the length direction of the guide frame 42111. At least part of the first transfer seat 42114 and at least part of the second transfer seat 42115 are located on the inner side of the guide frame 42111 and are threadedly connected to the driving screw 42113.

It is understandable that, as shown in FIG6 , the driving screw 42113 is arranged on the inner side of the guide platform 42111 along the length direction of the guide platform 42111. The guide platform 42111 is provided with a slide rail along the outer edge of its length direction. Correspondingly, the outer edges of the bottoms of the first transfer seat 42114 and the second transfer seat 42115 are both provided with a slider. Among them, the part of the first transfer seat 42114 located on the inner side of the guide platform 42111 is sleeved on the first screw segment 42100, and the part of the second transfer seat 42115 located on the inner side of the guide platform 42111 is sleeved on the second screw segment 42200. Therefore, when the rotating motor 42112 drives the driving screw 42113 to rotate, the first transfer seat 42114 and the second transfer seat 42115 are guided to make linear motion along the length direction of the guide platform 42111 through the cooperation between the slide rail and the slider, thereby increasing the reliability of the connection between the first transfer seat 42114 and the second transfer seat 42115 and the driving screw 42113, improving the stability of the movement of the first robotic arm 4212 and the second robotic arm 4213, and this design ensures the structural compactness of the entire driving platform 4211.

In some embodiments, specifically, as shown in FIG. 7 , in the packaging material rolling shaft device 4 provided by the present invention, at least one of the first robotic arm 4212 and the second robotic arm 4213 includes a linear lifting module 42122 and a linear translation module 42123 .

The linear lifting module 42122 is disposed on the driving platform 4211 , the slide of the linear lifting module 42122 is connected to the linear translation module 42123 , and the slide of the linear translation module 42123 is provided with an execution terminal 42121 .

Among them, the slide of the linear lifting module 42122 is used to control the linear translation module 42123 to rise and fall in the vertical direction, and the slide of the linear translation module 42123 is used to control the axial translation of the execution terminal 42121 along the packaging material roll 100.

It is understandable that the specific structures of the first robot arm 4212 and the second robot arm 4213 can be the same. Taking the first robot arm 4212 as an example, as shown in FIG7 , the first robot arm 4212 includes a linear lifting module 42122 and a linear translation module 42123. The linear lifting module 42122 is disposed on the first transfer seat 42114 and is arranged vertically. Along the extension direction of the linear lifting module 42122, the linear lifting module 42122 is provided with a slide. The linear translation module 42123 is movably disposed on the slide and extends in the horizontal direction.

The execution end 42121 of the first robot arm 4212 is arranged on the slide of the linear translation module 42123. The slide of the linear lifting module 42122 can drive the linear translation module 42123 to rise in the vertical direction, so that the execution end 42121 of the first robot arm 4212 located on the linear translation module 42123 can rise to the height where the center hole of the packaging material roll 100 is located. Further, the slide of the linear translation module 42123 can drive the execution end 42121 of the first robot arm 4212 to move along the axial direction of the packaging material roll 100, so that the execution end 42121 of the first robot arm 4212 reaches the location of the center hole of the packaging material roll 100 and is connected to the protective film.

After the execution end 42121 of the first mechanical arm 4212 is connected to the protective film, the slide of the linear translation module 42123 drives the execution end 42121 of the first mechanical arm 4212 to move in the radial direction of the packaging material roll 100 in the direction away from the center hole of the packaging material roll 100, thereby tearing off the protective film in the area where the center hole of the packaging material roll 100 is located. Then, the slide of the linear lifting module 42122 drives the linear translation module 42123 to descend, so that the execution end 42121 of the first mechanical arm 4212 returns to the initial position to provide an operable space for the packaging material roll threading device 43. Thus, the execution ends 42121 of the first mechanical arm 4212 and the second mechanical arm 4213 successively complete the actions of the first film tearing state and the second film tearing state.

Optionally, the linear lifting module 42122 and the linear translation module 42123 are both linear motor modules, which belong to the prior art and will not be described in detail here.

Specifically, as shown in FIG. 7 , the packaging material rolling and threading shaft device 4 provided by the present invention, the execution end 42121 includes a mechanical claw 4210 and a negative pressure adsorption head 42103 .

The mechanical claw 4210 is used to be hung on the protective film, and the negative pressure adsorption head 42103 is used to be adsorbed on the surface of the protective film.

It is understandable that, as shown in Fig. 7, the mechanical claw 4210 includes a connecting arm 42101 and a hook head 42102. One end of the connecting arm 42101 is connected to the slide of the linear translation module 42123, and the other end is connected to the hook head 42102. The hook head 42102 is used to hang on the protective film.

The execution end 42121 of the first robot arm 4212 and the second robot arm 4213 tears off the protective film by configuring the mechanical claw 4210. Specifically, one end of the connecting arm 42101 is movably arranged on the slide of the linear translation module 42123, and the other end is fixedly connected to the hook head 42102. On the one hand, the connecting arm 42101 can provide support for the hook head 42102; on the other hand, the connecting arm 42101 can guide the hook head 42102 to move along the axial direction of the packaging material roll 100. The slide of the linear translation module 42123 drives the connecting arm 42101 to move in the direction close to the packaging material roll 100 to the area where the central hole of the packaging material roll 100 is located, so that the hook head 42102 hooks the protective film.

As shown in FIG7 , the connecting arm 42101 and the hook head 42102 are arranged vertically, and the connecting arm 42101 is arranged to extend along the axial direction of the packaging material roll 100. One end of the connecting arm 42101 crosses the slide of the linear translation module 42123 along the axial direction of the packaging material roll 100 to ensure the stability of the connection between the connecting arm 42101 and the linear translation module 42123; the other end is exposed from the linear translation module 42123. The hook head 42102 is arranged at the portion of the connecting arm 42101 exposed from the linear translation module 42123, and is arranged vertically with the hook head 42102, so that the hook head 42102 can adapt to the structural layout of the first mechanical arm 4212 and the second mechanical arm 4213, align with the central hole of the packaging material roll 100, and then hook the protective film.

Furthermore, the execution terminal 42121 includes a negative pressure adsorption head 42103. The negative pressure adsorption head 42103 is extended along the axial direction of the packaging material roll 100, and the adsorption end of the negative pressure adsorption head 42103 is used to be adsorbed on the surface of the protective film.

It is understandable that the negative pressure adsorption head 42103 is arranged at the part of the connecting arm 42101 exposed to the linear translation module 42123, and is arranged side by side with the hook head 42102. The negative pressure adsorption head 42103 can move with the hook head 42102 to the area where the central hole of the packaging material roll 100 is located. The negative pressure adsorption head 42103 can adsorb the protective film while the mechanical claw 4210 tears off the protective film. The two cooperate with each other to ensure the reliability of the film tearing operation.

In some embodiments, as shown in FIG. 7 , a plurality of negative pressure adsorption heads 42103 are provided, and the plurality of negative pressure adsorption heads 42103 are arranged side by side to simultaneously adsorb the protective film, thereby increasing the adsorption force on the protective film. The plurality of negative pressure adsorption heads 42103 adsorb the protective film together, which is more conducive to the hook head 42102 successfully hooking the protective film, thereby ensuring the accuracy and efficiency of film tearing of the packaging material roll film tearing device 42. Optionally, the number of negative pressure adsorption heads 42103 can be three, four, or six.
