Description

Technical Field

[0001] The present invention relates to the field of packaging of thin films, and particularly to a fastening device for clamping plates and plugs. Background Art

[0002] In the field of packaging of thin film rolls, the existing packaging methods mainly include vertical packaging, horizontal packaging, and suspended packaging. In the vertical packaging during the packaging and transportation process of the packaging film material, the end face of the thin film will be pressed to cause the phenomenon of flanging, while in the horizontal packaging, the side of the film roll 62 will directly contact and be pressed, which will cause the thin film to be deformed under pressure and affect the subsequent processing quality.

[0003] Therefore, as Figure 1 shown, for some thin films with higher quality requirements, generally the suspended packaging process that has emerged in recent years needs to be adopted. Suspended packaging is to place the support clamping plates 63 at both ends of the film roll 62. A through hole 61 is opened in the middle of the support clamping plate 63, so that the core of the film roll 62 penetrates into the through hole 61, and a plug 64 is inserted into the core. The support clamping plate 63 is mostly rectangular and can be placed vertically. The clamping plates of the support clamping plate 63 are tied with plastic steel belts. After the packaging is completed, the film roll 62 is suspended between the two clamping plates. As Figure 2 、 Figure 3 shown, after the plug 64 is installed on the film roll, the plug 64 penetrates into the core, and at the same time, the support clamping plate 63 is pressed by the plug 64.

[0004] In addition, in the prior art, generally, when fastening the plug and the clamping plate to the film roll, it is necessary to manually operate the overhead crane to lift the support clamping plate 63, and at the same time, the film roll needs to be placed on a platform, and the width dimension of the platform needs to be slightly smaller than the length of the film roll to avoid interference between the support clamping plate and the platform. During installation, the plug is inserted into the core by knocking. By using such a method, it is easy to damage the film roll, and moreover, the efficiency of manual operation is relatively low. And for film rolls with different length dimensions, platforms with different widths need to be used. If platforms with a smaller width dimension are used for all film rolls of all specifications, for some larger film rolls, the contact surface between them and the platform is likely to have a large stress, resulting in damage to the film roll.

[0036] Refer to Figures 1 to 15, A fastening device for a splint and a plug, comprising a frame, a left-right driving device 16, a film roll supporting device 17, and a fastening device 18; the left-right driving device 16 is arranged on the frame; the film roll supporting device 17 is fixed on the frame, and the film roll supporting device 17 is used to support a horizontally placed film roll; one or two fastening devices 18 are provided, and the fastening devices 18 are arranged on the left side and / or the right side of the film roll supporting device 17. The fastening device 18 is used to fasten the plug and the supporting splint to the film roll on the film roll supporting device 17. The left-right driving device 16 drives the fastening device 18, and the left-right driving device 16 drives the fastening device 18 to reciprocate in the left-right direction.

[0037] As can be seen from the above, the horizontally placed film roll is supported by the film roll supporting device 17. The left-right driving device 16 drives the fastening device 18 to move left and right. The fastening device 18 fastens the supporting splint and the plug to the film roll placed on the film roll supporting device 17, realizing the mechanized fastening and packaging of the film roll.

[0038] In some embodiments, two fastening devices 18 are provided. The two fastening devices 18 are respectively arranged on the left and right sides of the film roll supporting device 17. The left-right driving device 16 drives the two fastening devices 18 to approach or move away from each other synchronously. This structure is simple and convenient to set. The left-right driving device 16 drives the two fastening devices 18 to approach or move away from each other synchronously, which is very convenient to use.

[0039] Optionally, the left-right driving device 16 includes two synchronous belts, and the two synchronous belts are respectively drivingly connected to a corresponding fastening device 18.

[0040] Furthermore, a guide rail 19 is provided on the frame, and the fastening device 18 is slidably engaged with the guide rail.

[0041] In some embodiments, the film roll supporting device 17 includes a first support frame 0, a lifting assembly 1, and a first support plate 2; the first support frame 0 is fixed on the frame, multiple lifting assemblies 1 are provided, and the fixed parts of the lifting assemblies 1 are fixed on the first support frame 0; multiple first support plates 2 are provided, and the multiple first support plates 2 are arranged in the left-right direction. The first support plate 2 is fixed on the movable part of the lifting assembly 1. The lifting assembly 1 drives the first support plate 2 to reciprocate in the up-down direction, and the first support plate 2 is used to support the film roll.

[0042] As can be seen from the above, the lifting assembly 1 is used to drive the first support plate 2 to lift. When in use, the user can select the number of first support plates 2 according to the size of the film roll 62. Thus, it can adapt to various film rolls 62 with different specifications and sizes and support the film roll 62, which is very convenient to use.

[0043] In some embodiments, the film roll support device 17 further includes a central support plate 3, the central support plate 3 is fixedly connected to the first support frame 0, and a plurality of the first support plates 2 are symmetrically arranged on the left and right sides of the central support plate 3. This structure is simple and convenient to set up. Through the setting of this structure, it is convenient to place the film roll that has completed central positioning. In addition, during use, the central support plate 3 can be arranged above the lifter 11, so that the first support plates 2 are respectively arranged on the left and right sides of the central support plate 3, and its structure is compact.

[0044] In addition, in actual use, in order to automatically buckle and support the clamping plates 63 and the plugs 64 at both ends of the film roll 62, it is necessary to position the center of the film roll 62. In the case where the center of the film roll 62 has been positioned, through the setting of the central support plate 3, it is convenient to place the film roll 62.

[0045] In some embodiments, the highest point of the stroke of each of the first support plates 2 is flush with the central support plate 3. This structure is simple and convenient to set up. Through the setting of this structure, it is ensured that the first support plate 2 and the central support plate 3 are flush when supporting the film roll 62, avoiding damage due to excessive stress received by a local part on the side of the film roll 62 caused by the height difference between the first support plate 2 and the central support plate 3.

[0046] In some embodiments, the lifting assembly 1 includes a lifter 11 arranged on the first support frame 0, a guide rod 12 arranged on the first support frame 0, a lifting slider 13 slidably engaged with the guide rod 12, and a connecting frame 14 fixedly connected to the lifting slider 13. The first support plate 2 is fixedly connected to the connecting frame 14. All the lifters 11 are arranged in the front-rear direction, the connecting frame 14 extends to the left and right sides with the lifting slider 13 as the center, and the first support plates 2 are symmetrically arranged on both the left and right sides of each connecting frame 14. This structure is simple and convenient to set up. All the lifters 11 are arranged in the front-rear direction, and each connecting frame 14 extends to the left and right sides with the corresponding lifting slider 13 as the center, which is convenient to be set into a symmetrical structure, making the structure more stable. In addition, the lifters 11 are arranged in the front-rear direction, so that the interval between adjacent connecting frames 14 can be realized, playing a role of avoiding interference between adjacent connecting frames 14.

[0047] In actual use, in each lifting assembly 1, preferably, two guide rods 12 are provided, and the lifter 11 is arranged between the two guide rods 12. In some embodiments, in each lifting assembly 1, the two guide rods 12 are arranged in the left-right direction.

[0048] Since all the first pallets 2 extend in the left - right direction, the length that each connecting plate extends out should be adapted to the positions of the corresponding two first pallets 2. Preferably, the two first pallets 2 of the same connecting frame 14 are symmetrical.

[0049] In some embodiments, the lifter 11 is an electric cylinder or a rodless cylinder. Optionally, a rodless cylinder is adopted in this embodiment.

[0050] In some embodiments, the film roll support device 17 further includes a second support frame and a lifting mechanism 5 arranged on the second support frame. The first support frame 0 is fixed on the lifting mechanism 5, and the lifting mechanism 5 drives the first support frame 0 to reciprocate in the up - down direction.

[0051] In actual use, in order to fasten the plug 64 and the supporting clamp 63 to the film roll 62, it is necessary to fix the position of the center of the film roll 62 to accurately locate the center of the film roll 62, so as to realize the fastening and installation of the plug 64 and the supporting clamp 63. When the film rolls 62 with different diameters are placed flat, the height of the center position of the film roll 62 is different, so it is necessary to adjust the height of the film roll 62.

[0052] Therefore, by driving the first support frame 0 to move in the up - down direction through the lifting mechanism 5, the height of the film roll 62 supported by the first pallet 2 and the center pallet 3 can be adjusted, thereby adjusting the height of the center of the film roll 62.

[0053] In some embodiments, a first recess 20 extending in the left - right direction is formed in the middle of the center pallet 3, and a second recess 30 extending in the left - right direction is formed in the middle of the first pallet 2. The first recess 20 and the second recess 30 are opposite to each other. This structure is simple and convenient to set. Through the setting of these recesses, the film roll 62 arranged in the first recess 20 and the second recess 30 can be limited to prevent the film roll 62 from easily rolling and falling. In addition, through the setting of the first recess 20 and the second recess 30, the contact area between the side surface of the film roll 62 and the first recess 20 and the second recess 30 can be effectively increased, thereby reducing the stress of the part of the film roll 62 under pressure and preventing the film roll 62 from being damaged.

[0054] Preferably, the first recess 20 and the second recess 30 are set as arc surfaces, and the openings of the arc surfaces face upward.

[0055] In some embodiments, the lifting mechanism 5 includes a vertical slide rail 51 fixed to the second support frame, a vertical slider 52 slidably engaged with the vertical slide rail 51, and a vertical electric screw rod 53 disposed on the second support frame. The vertical slider 52 is fixedly connected to the first support frame 0. The vertical electric screw rod 53 drives the vertical slider 52, and the vertical electric screw rod 53 drives the vertical slider 52 to reciprocate in the up and down directions. By driving the vertical slider 52 to reciprocate in the up and down directions through the vertical electric screw rod 53, since the vertical slider 52 is fixedly connected to the first support frame 0, the up and down movement of the first support frame 0 can be realized.

[0056] Preferably, two vertical slide rails 51 are provided. The vertical electric screw rod 53 is disposed between the two vertical slide rails 51, and the vertical slider 52 is slidably engaged with the two vertical slide rails 51 at the same time. Its structure is more stable.

[0057] In some embodiments, the second support frame includes a horizontal plate and two vertical plates. The two vertical plates are respectively fixedly connected to the left and right sides of the horizontal plate, such that the horizontal plate and the two vertical plates form a U-shaped. Two lifting mechanisms 5 are provided, and the lifting mechanisms 5 are disposed on the vertical plates, and the lifting mechanisms 5 are provided in one-to-one correspondence with the vertical plates. This structure is simple and convenient to set. Through the setting of this structure, the lifting of the first support frame 0 is more stable. During use, the two lifting mechanisms 5 move synchronously.

[0058] In certain embodiments, two vertical slide rails 51 are provided on each vertical plate, and a vertical electric screw rod 53 is disposed between the two vertical slide rails 51 on the same vertical plate.

[0059] In some embodiments, the fastening device 18 includes a fastening frame 013, a fixing plate 7, a suction cup 8, a first plug mounting shaft 9, an expansion assembly 10, and a material pushing assembly 011; the fastening frame 013 is arranged on the left-right moving device; the fixing plate 7 is fixed on the fastening frame 013, and the fixing plate 7 is arranged vertically; the suction cup 8 is used to fix the support clamping plate, and the suction cup 8 is on the surface of the fixing plate 7 facing the film roll support device 17; the first plug mounting shaft 9 is arranged on the fastening frame 013, the first plug mounting shaft 9 can slide left and right relative to the fastening frame 013, the first plug mounting shaft 9 extends in the left-right direction, and the first plug mounting shaft 9 is used to place plugs in an inserted manner; the expansion assembly 10 is arranged on the first plug mounting shaft 9, the expansion assembly 10 is used to position the through holes on the support clamping plate, and the expansion assembly 10 is used to position the core of the film roll, so that the through holes on the clamping plate are concentric with the core of the film roll; the material pushing assembly 011 is arranged on the fastening frame 013, the material pushing assembly 011 is drivingly connected to the first plug mounting shaft 9, and the material pushing assembly 011 drives the first plug mounting shaft 9 to reciprocate in the left-right direction.

[0060] During use, the user can first place the plug 64 on the first plug mounting shaft 9, make the first plug mounting shaft 9 pass through the through hole on the support clamping plate, and tighten the through hole by the expansion of the expansion assembly 10, so as to realize the positioning of the through hole. The first mounting plug is driven by the material pushing assembly 011 to move in the left-right direction to adjust the relative position between the suction cup 8 and the first mounting plug. Thus, the support clamping plate is fixed by the suction cup 8. After the support clamping plate is fixed, the expansion assembly 10 loosens the through hole. The user can move the film roll to the left relative to the first plug mounting shaft 9, so that the first plug mounting shaft 9 is inserted into the core. However, the expansion assembly 10 expands again to realize the positioning of the core of the film roll and fine-tune the film roll to achieve centering, ensuring that the through hole on the support clamping plate and the center of the core are concentric, so that the plug on the first plug mounting shaft 9 can be smoothly inserted into the through hole and the core to realize fastening.

[0061] Preferably, a plurality of the suction cups 8 are provided, and all the suction cups 8 are circumferentially and arrayed around the axis of the first plug mounting shaft 9.

[0062] In some embodiments, an avoidance hole 70 is formed in the fixing plate 7, and the avoidance hole 70 is used for the first plug mounting shaft 9 to pass through. Through the setting of this structure, it is convenient for the expansion assembly 10 on the first plug mounting shaft 9 to tighten the through hole on the support clamping plate to realize positioning and centering.

[0063] In some embodiments, a cavity is formed in the first plug mounting shaft 9, the expansion assembly 10 is disposed in the cavity, a plurality of openings 90 are formed in the side surface of the first plug mounting shaft 9, the expansion assembly 10 includes a pusher 101 fixedly connected to the first plug mounting shaft 9, an inner push shaft 103 disposed in the cavity, and a plurality of jaw blocks 102 disposed on the push shaft 103. The movable part of the pusher 101 is fixedly connected to the push shaft 103. The jaw blocks 102 are disposed in the openings 90, and the jaw blocks 102 are slidably engaged with the openings 90. The openings 90 and the jaw blocks 102 are arranged in one-to-one correspondence. A plurality of card slots 1031 are formed in the push shaft 103. The depth of the card slots 1031 gradually increases in the direction close to the film roll support device 17. A convex rib 1032 is provided on the inner wall of the card slot 1031. The extending direction of the convex rib 1032 is arranged along the extending direction of the depth of the card slot 1031. The convex rib 1032 and the card slot 1031 are respectively in concave-convex fit with the jaw block 102. The jaw block 102 is slidably engaged with the card slot 1031, and the jaw block 102 is slidably engaged with the convex rib 1032. This structure is simple and convenient to set. The expansion assembly 10 is disposed in the cavity, and its structure is compact, which can reduce the weight of the plug mounting shaft.

[0064] When the pusher 101 drives the push shaft 103 to move in the direction close to the film roll support device 17, the jaw block 102 is pushed out in the depth direction of the opening 90 away from the axis of the first plug mounting shaft 9 as the depth of the card slot 1031 decreases under the limiting action of the convex rib 1032, realizing the tightening action.

[0065] When the pusher 101 drives the push shaft 103 to move in the direction away from the film roll support device 17, the clamping block retracts into the cavity in the depth direction of the opening 90 close to the axis of the first plug mounting shaft 9 as the depth of the card slot 1031 increases under the limiting action of the convex rib 1032, realizing the loosening action.

[0066] In some embodiments, the end surface of the jaw block 102 away from the axis of the first plug mounting shaft 9 is provided as an inclined surface, and the height of the inclined surface gradually increases from right to left. Through the setting of this structure, it is convenient to guide during the process of inserting into the through hole or the core.

[0067] In some embodiments, a flange 91 is provided on the first plug mounting shaft 9, and the flange 91 is used to abut against the plug provided on the first plug mounting shaft 9. The opening 90 is provided between the flange 91 and the film roll support device 17. Through the arrangement of the flange 91, it is convenient to abut against the end face of the plug facing away from the film roll support device 17, so that under the action of the left and right driving device 16 driving the fastening device 18 to move, after the first plug mounting shaft 9 is inserted into the through hole on the support clamping plate and the core, the plug is inserted into the through hole and the core.

[0068] In some embodiments, a second plug mounting shaft 012 is provided on the end face of the first plug mounting shaft 9 close to the film roll support device 17. The outer diameter of the second plug mounting shaft 012 is smaller than the outer diameter of the first plug mounting shaft 9, and the second plug mounting shaft 012 is used for mounting the plug.

[0069] Preferably, the opening 90 is provided between the second plug mounting shaft 012 and the flange 91.

[0070] In the case of some smaller apertures, such as Figure 3 As shown, for example, when a plug about three inches in size is fastened, the corresponding sized plug can be directly inserted through the second mounting shaft and directly fastened and installed into the through hole and the core adapted to the size of the plug. Since the size of the plug is small, the interference area caused by the deviation is small, and the damage to the film roll caused by forced insertion is small. Moreover, when forcedly inserted into the core and the through hole, the through hole and the core can also be centered under the guiding action of the plug itself. Therefore, the expansion assembly 10 can be not used. As in Figure 2 As shown, when a plug about six inches in size is required, the expansion assembly 10 is needed.

[0071] In some embodiments, the fastening frame 013 includes a main body frame 0131 and a sleeve 0132 fixed on the main body frame 0131. The fixing plate 7 is fixedly connected to the sleeve 0132 through a transition frame 0133, and the first plug mounting shaft 9 is slidably fitted with the sleeve 0132 in the left and right directions through a bearing.
