DETAILED DESCRIPTION

[0025] The present invention provides a vertical film roll unwinding device and a film roll classification unwinding conveyor line. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0026] In this article, the conveying direction is the sequential connection of the horizontal unwinding device, the turning conveyor line 1 and the horizontal conveyor line 2, that is, Figure 4 The direction indicated by the arrow in the middle: "front" is the same as the conveying direction, and "back" is opposite to "front".

[0027] See also Figure 2-Figure 4The present invention provides a vertical film roll unwinding device, comprising a flip conveyor line 1, a horizontal conveyor line 2 connected to the flip conveyor line 1, a centering mechanism 3 arranged on both sides of the horizontal conveyor line 2, and a stacking mechanism 4 arranged above the horizontal conveyor line 2; the flip conveyor line 1 is used to flip the film roll and convey the film roll forward, so that one end surface of the film roll is pressed against the flip conveyor line 1; a stacking station 5 is provided on the horizontal conveyor line 2; the centering mechanism 3 is used to push the film roll to the stacking station 5; the stacking mechanism 4 is used to grab the film roll at the stacking station 5 and drive the film roll to move up and down to achieve stacking.

[0028] In practical applications, film rolls with larger diameters and shorter lengths will be stacked and unrolled through the film roll vertical unrolling device 7 provided by the present invention, and film rolls with larger diameters and shorter lengths can be understood as film rolls with a film roll diameter: film roll length ≥ 3:1; and film rolls with smaller diameters and longer lengths will be horizontally arranged and unrolled through the film roll horizontal unrolling device 6, and film rolls with smaller diameters and longer lengths can be understood as film rolls with a film roll diameter: film roll length < 3:1. Workers select vertical unrolling or horizontal unrolling for film rolls based on the ratio of the film roll diameter to the length.

[0029] The working method of the vertical unwinding is briefly described as follows: when the first film roll is conveyed to the vertical film roll unwinding device 7, the flip conveyor line 1 first receives the first film roll. At this time, the peripheral wall of the first film roll is pressed against the flip conveyor line 1, and the axis of the first film roll is parallel to the conveying direction. Then the flip conveyor line 1 flips the film roll 90°, so that the end face of the first film roll is pressed against the flip conveyor line 1, and the axis of the first film roll is parallel to the vertical direction. Then the flip conveyor line 1 conveys the first film roll to the horizontal conveyor line 2, and the horizontal conveyor line 2 conveys the first film roll forward to the stacking station 5. Since the first film roll will be displaced after being flipped, it is impossible to determine whether the first film roll is accurately moved to the stacking station 5 at this time, so the position of the first film roll is corrected by the centering mechanism 3, and the first film roll is stacked. It is pushed accurately to the stacking station 5, and the next film roll (hereinafter referred to as the second film roll) is also turned 90 degrees through the turning conveyor line 1 and transported to the horizontal conveyor line 2. Before the second film roll enters the horizontal conveyor line 2, the stacking mechanism 4 grabs the first film roll and lifts the first film roll to a suitable height, and then the horizontal conveyor line 2 transports the second film roll forward to the stacking station 5. Similarly, the position of the second film roll is corrected by the centering mechanism 3, and the second film roll is accurately pushed to the stacking station 5. At this time, the second film roll is located directly below the first film roll. Then the stacking mechanism 4 stacks the first film roll on the second film roll, and finally releases the first film roll. The first film roll and the second film roll are transported forward through the horizontal conveyor line 2, waiting for further handling and shipment. Of course, the number of stacked film rolls can be 3 or more. On the basis of completing the stacking of two film rolls, the stacking is continued according to the above-mentioned stacking method, which will not be repeated here.

[0030] Specifically, the centering mechanism 3 includes two symmetrically arranged jaw assemblies, each of which includes a bracket 31, two arc-shaped jaws 32 symmetrically arranged on the top of the bracket 31, and a jaw driving assembly 33 arranged on the bracket 31 and used to drive the two arc-shaped jaws 32 to close or open each other; one end of the two arc-shaped jaws 32 is rotatably arranged on the bracket 31. In the initial state, the two arc-shaped jaws 32 in each jaw assembly are opened toward the horizontal conveyor line 2 to form a "W" structure. When the horizontal conveyor line 2 transports the film roll to the stacking station 5, the two jaw driving assemblies 33 synchronously drive the four arc-shaped jaws 32 to close toward the stacking station 5, and the free ends of the four arc-shaped jaws 32 form a push correction for the film roll. When the free ends of the four arc-shaped jaws 32 clamp the film roll, it means that the film roll is accurately positioned at the stacking station 5.

[0031] Furthermore, the arc-shaped claw 32 includes an upper arc plate 321, a lower arc plate 322, and a plurality of push rollers 323 vertically and rotatably arranged between the upper arc plate 321 and the lower arc plate 322; these push rollers 323 are arranged on the free end of the arc-shaped claw 32, and the push rollers 323 are used to push the film roll. On the one hand, the friction impact of the arc-shaped claw 32 on the film roll can be reduced, and the contact is more flexible. On the other hand, the film roll is adaptively rotated or moved under the action of the push rollers 323, and is better moved to the stacking station 5. The same end of the upper arc plate 321 and the lower arc plate 322 is fixedly connected by a sleeve 324, and a vertical fixed shaft (not visible in the figure) is provided on the bracket 31. The sleeve 324 is sleeved on the fixed shaft and connected to the fixed shaft through a bearing, so as to ensure that the arc-shaped claw 32 swings smoothly and is better assembled with the clamping jaw drive assembly 33.

[0032] Preferably, the clamp driving assembly 33 includes a cylinder bracket 331, a clamp driving cylinder 332 arranged on the cylinder bracket 331, a U-shaped joint 333 is provided on the end of the piston rod of the clamp driving cylinder 332, a transmission sheet 334 is fixed on each sleeve 324, each transmission sheet is connected to the U-shaped joint 333 through a connecting rod 335, one end of the connecting rod 335 is hinged to the transmission sheet 334, and the other end is hinged to the U-shaped joint 333. The clamp driving cylinder 332 synchronously drives the two arc-shaped claws 32 to open or close under the rotation of the U-shaped joint 333 and the transmission sheet 334 through the extension and contraction of the piston rod, and has an ingenious structure and good action synchronization.

[0033] Specifically, the stacking mechanism 4 includes two upright frames 41, a crossbeam 42 connecting the tops of the two upright frames 41, two first rails 43 vertically arranged between the two upright frames 41, and a roll-holding driving mechanism 44 for driving the two first rails 43 to move closer to or away from each other; each first rail 43 is slidably connected with a roll-holding plate 45, and the roll-holding end face of the roll-holding plate 45 is an arc-shaped surface and extends vertically, so that the roll-holding end face better fits the peripheral wall of the film roll, increases the contact area between the roll-holding plate 45 and the film roll, improves the lifting friction of the film roll, and has the ability to grab several film rolls at a time. The first rail 43 is provided with a lifting driving mechanism 46 for driving the roll-holding plate 45 to move up and down, and the lifting driving mechanism 46 can adopt an electric push rod, a linear module, a screw mechanism, etc., and its main effect is to provide an output end of linear motion. During stacking, the roll-holding drive mechanism 44 drives the two first rails 43 and the roll-holding plate 45 to move synchronously toward the stacking station until the two roll-holding plates 45 clamp the film roll, and then the lifting drive mechanism 46 drives the roll-holding plate 45 to move upward, so that the film roll is lifted to a certain height, so that the next film roll can have space to enter the stacking station, and when the next film roll is accurately placed at the stacking station, the lifting drive mechanism 46 drives the roll-holding plate 45 to descend, and stack the previous film roll on the next film roll. It can be seen that the centering mechanism 3 and the stacking mechanism 4 cooperate with each other to automatically complete the stacking of film rolls, which is efficient and safe, and solves the problems caused by manual stacking.

[0034] Furthermore, a base 47 is provided at the bottom end of the first track 43, a second track 48 extending left and right is provided on the ground, the base 47 and the second track 48 are slidably connected, a third track (not visible in the figure) is provided on the bottom surface of the crossbeam 42, and the top end of each first track 43 is slidably connected to the third track. Through such an arrangement, the first track 43 always maintains vertical extension under the positioning effect of the second track 48 and the third track, and will not tilt during the movement, and the first track 43 has less movement resistance and can move smoothly left and right.

[0035] In this embodiment, the wrapping and rolling driving mechanism 44 includes two wrapping and rolling driving cylinders, the cylinder bodies of the wrapping and rolling driving cylinders are fixed on the stand 41 , and the piston rod ends of the wrapping and rolling driving cylinders are connected to the first rail 43 .

[0036] Specifically, the overturning conveyor line 1 comprises a base frame 11, an overturning frame 12 rotatably arranged on the base frame 11, a horizontal conveying frame 13 arranged downstream of the overturning frame 12, a plurality of first guide roller assemblies 14 arranged on the overturning frame 12, a first guide roller driving mechanism 15 for driving all guide roller assemblies to move synchronously, and an overturning driving mechanism for driving the overturning frame 12 to overturn toward the horizontal conveying frame 13; a plurality of second guide roller assemblies 18 and a second guide roller driving mechanism 17 for driving all second guide roller assemblies 18 to move synchronously are arranged on the horizontal conveying frame 13. Driven by the first guide roller assemblies 14, the film roll completely enters the overturning frame 12 in a horizontal state, and then the overturning driving mechanism drives the overturning frame 12 to overturn 90° toward the horizontal conveying frame 13, so that the film roll overturns and falls on the second guide roller assembly 18, that is, switches from a horizontal state to a vertical state, and then the second guide roller assembly 18 drives the film roll to enter the horizontal conveying line 2.

[0037] Furthermore, the first guide roller assembly 14 includes two first conveying rollers that are symmetrically arranged on the left and right, and the two first conveying rollers are inclined to form a V-shaped positioning groove; a driven gear is provided at one end of each first conveying roller. The center of gravity of the coil is positioned on the V-shaped positioning groove, which plays a central positioning role to prevent the coil from shaking or rolling during movement.

[0038] In this embodiment, the first guide roller driving mechanism 15 includes a first guide roller driving motor, a driving gear arranged at the output end of the first guide roller driving motor, and the driving gear is connected to all driven gears through a chain. The second guide roller assembly 18 is a second conveying roller extending in the left-right direction, and the second guide roller driving mechanism 17 drives all second conveying rollers to move synchronously through a chain transmission method.

[0039] In this embodiment, the flip driving mechanism includes a plurality of flip pneumatic push rods 16, the guide sleeve end of the pneumatic push rod is hinged to the base frame 11, and the push rod end of the pneumatic push rod is hinged to the flip frame 12. When the push rod of the pneumatic push rod is extended, the flip frame 12 swings toward the horizontal conveying frame 13, so that the film roll is flipped 90 degrees, that is, the film roll is converted from a horizontal state to a vertical state.

[0040] The present invention also provides a film roll classification unwinding conveyor line, comprising a vertical film roll unwinding device 7 of any of the above-mentioned embodiments or any combination of the above-mentioned embodiments and a horizontal film roll unwinding device 6 arranged upstream of the vertical film roll unwinding device 7, the horizontal film roll unwinding device 6 comprising a horizontal base frame 61 and a swing frame 62 swingably arranged on the horizontal base frame 61, the swing frame 62 being connected to the horizontal base frame 61 via a hinge 67, a plurality of third guide roller assemblies 63 and a third guide roller driving mechanism 64 for driving all the third guide roller assemblies 63 to move synchronously are arranged on the swing frame 62, a roll unwinding storage rack 65 is arranged on one side of the horizontal base frame 61, and a side push driving mechanism for driving the swing frame 62 to swing toward the roll unwinding storage rack 65 is arranged on the horizontal base frame 61.

[0041] After all the film rolls are packaged, their axes will be parallel to the conveying direction. At this time, the staff can flexibly select the vertical or horizontal unwinding method for the film rolls according to the ratio of the diameter to the length of the film rolls. It is highly applicable and highly automated, and can effectively improve the handling efficiency and delivery rate. If the horizontal unwinding method is adopted, when the film roll completely enters the swing frame 62, the forward conveying of the film roll is stopped. At this time, the side push drive mechanism drives the swing frame 62 to swing toward the unwinding storage rack 65, so that the swing frame 62 tilts, so that the film roll rolls autonomously roll onto the unwinding storage rack 65 for caching, waiting for further transportation by the forklift. When the vertical unwinding method is adopted, the film roll enters the vertical unwinding device 7 of the film roll through the swing frame 62, and the vertical unwinding device 7 of the film roll begins to stack the film rolls. Since the above description has been made for the vertical unwinding device 7 of the film roll, the technicians in this field should be able to understand it in conjunction with the accompanying drawings, so the vertical unwinding device 7 of the film roll will not be described here.

[0042] Preferably, the side-push driving mechanism includes a plurality of side-push driving cylinders 66, the cylinder body of each side-push driving cylinder 66 is hinged to the horizontal base frame 61, and the piston rod end of each side-push driving cylinder 66 is hinged to the swing frame 62; the swing frame 62 is initially placed horizontally, and the piston rod of the side-push driving cylinder 66 extends upward, driving the swing plate to tilt toward the unwinding storage rack 65, thereby providing power and guidance for the film roll to roll down.

[0043] In this embodiment, the roll-out storage rack 65 includes two support plates 651 which are parallel to each other and extend in the left-right direction. A stopper 652 is provided at one end of the support plate 651 away from the horizontal base frame 61, and the film roll will be blocked by the stopper 652 to prevent the film roll from rolling off the support plate 651; a support column 653 is provided at the bottom of one end of the support plate 651 close to the horizontal base frame 61 and is rotatably connected thereto; and a slope adjustment mechanism is provided at one end of the support plate 651 away from the horizontal base frame 61. The slope adjustment mechanism is a screw lifter 654, the top end of the screw of the screw lifter 654 supports the support plate 651, and a hand wheel is provided on the screw lifter 654. The main body of the screw lifter 654 is fixed on the ground. The hand wheel is manually driven to rotate, so as to control the screw lift and drive the support plate 651 to swing, thereby swinging the tilt angle of the support plate 651, and then making the film roll generate suitable rolling potential energy.
