Description

Technical Field

[0001] The present invention relates to the technical field of film roll packaging, and particularly relates to a film roll handling device for suspended packaging. Background Art

[0002] The coil material is a cylindrical plastic film roll. After the coil material is manufactured, it needs to be transported to various places for sale. In order to protect the integrity of the coil material during transportation, reduce wear, and increase the transportation quantity, it is necessary to perform suspended packaging on the coil material. Suspended packaging can be understood as first independently packaging a single coil material, wrapping the surface of the coil material with bubble film, then buckling the two ends with a paper cover and a foam pad, and fixing them with tape winding; then installing vertical clamping plates and plugs at both ends of the coil material, and then bundling the two vertical clamping plates, so that the coil material is suspended between the two vertical clamping plates. After the suspended packaging is completed, it is necessary to transport the film roll from the bundling station to the palletizing station, and several film rolls are palletized on a pallet for the forklift to carry and ship. Since after bundling, the bundling belts between the two vertical clamping plates are located at the top and bottom of the vertical clamping plates, in order to avoid damage and disconnection of the bundling belts when palletizing, it is necessary to flip the film roll 81 by 90°, so that the bundling belts 83 are located on the left and right sides of the vertical clamping plates 82, as Figure 7 shown; the flipping and handling of the existing coil materials are generally assisted by manually controlling a crane, that is, inserting a supporting rod into the core of the coil material, then the crane lifting the two ends of the coil material, and the staff applying force to push the coil material to flip. Not only is the labor intensity of the staff large, but also safety accidents are prone to occur. Therefore, it is urgent to automate the flipping and handling operations of the coil materials.

Detailed implementation manners

[0026] The present invention provides a film roll handling device for suspended packaging. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of 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 protection scope of the present invention.

[0027] Please refer to Figures 1 - 6, the present invention provides a film roll handling device for suspension packaging, which includes two symmetrically arranged vertical frames 1, a sliding frame 2 that spans the two vertical frames 1 and is slidably arranged on the two vertical frames 1, a front-back driving assembly 3 for driving the sliding frame 2 to move back and forth, a lifting frame 4 that is slidably arranged on the sliding frame 2, a lifting driving assembly 5 for driving the lifting frame 4 to move up and down, two flipping grippers 6 that are slidably arranged at the bottom of the lifting frame 4, and a grasping driving mechanism 7 for driving the two flipping grippers 6 to approach or move away from each other; the two flipping grippers 6 are used to clamp the film roll and flip the film roll. The front-back driving assembly 3, the lifting driving assembly 5, the grasping driving mechanism 7, and the flipping grippers 6 are all controlled to work by a PLC control system.

[0028] After the film roll undergoes suspension packaging, it is transported from the bundling station to the grasping station by a transport cart 84. At this time, the film roll 81 is located between the two flipping grippers 6. Since the upstream equipment has obtained the diameter of the film roll, the two flipping grippers 6 are driven by the lifting driving assembly 5 and the front-back driving assembly 3 to be centered with the film roll. Then, the grasping driving mechanism 7 drives the two flipping grippers 6 to move towards the film roll. After the two flipping grippers 6 clamp the film roll, the lifting driving assembly 5 drives the film roll on the flipping grippers 6 to move up, so that the film roll is separated from the transport cart; then the front-back driving assembly 3 drives the film roll on the flipping grippers 6 to move towards the palletizing station. During the movement, the flipping grippers 6 drive the film roll to automatically complete a 90° flip, so that the bundling straps located between the two vertical clamping plates 82 are flipped from the original positions at the top and bottom of the vertical clamping plates to the left and right sides of the vertical clamping plates, avoiding damage and breakage of the bundling straps due to extrusion during palletizing. Finally, the lifting driving assembly 5 drives the film roll on the flipping grippers 6 to descend to the palletizing station, and the two flipping grippers 6 move away from each other to release the film roll.

[0029] Compared with the prior art, the film roll handling device provided by the present invention can automatically complete the handling and flipping of the film roll. The two flipping grippers 6 are driven by the grasping driving mechanism 7 to grasp the film roll, and the film roll is transferred between workstations under the drive of the front-back driving assembly 3 and the lifting driving assembly 5. The flipping operation of the film roll is synchronously completed during the handling process, which is efficient and fast, without the need for staff to assist in handling, and has a high degree of automation.

[0030] Specifically, the flipping gripper 6 includes a suspension bracket 61 slidably connected to the bottom of the lifting frame 4, a positioning rotating shaft 62 rotatably arranged on the suspension bracket 61, a flipping driving device 63 drivingly connected to the positioning rotating shaft 62, and a pressing plate 622 fixedly arranged on the positioning rotating shaft 62; a positioning round head 65 axially movable relative to the positioning rotating shaft 62 is sleeved on the positioning rotating shaft 62, a position sensor 661 is arranged on the pressing plate 622, and a round head position contact piece 662 for triggering the position sensor 661 is arranged on the positioning round head 65; a plurality of elastic limiting mechanisms 67 for limiting the moving stroke of the positioning round head 65 are arranged between the positioning round head 65 and the pressing plate 622; a plurality of flipping anti-slip components 68 are arranged on the pressing plate 622, and the flipping anti-slip components 68 are used to keep the vertical clamping plate and the pressing plate 622 relatively stationary.

[0031] If the film roll is suspended and packaged with a small plug 691 (the diameter of the plug is 3 inches), the positioning rotating shaft 62 is inserted into the center of the small plug 691, and the positioning rotating shaft 62 is in clearance fit with the small plug 691. The positioning rotating shaft 62 supports the film roll, and the clamping end face of the positioning round head 65 abuts against the peripheral edge protrusion of the small plug 691. As the flipping gripper 6 continues to move towards the center of the film roll, the elastic limiting mechanism 67 provides a thrust to the positioning round head 65, so that the clamping end face of the positioning round head 65 always presses against the peripheral edge protrusion of the small plug 691 during the process of the pressing plate 622 gradually approaching the positioning round head 65; at the same time, all the flipping anti-slip components 68 press against the vertical clamping plate, increasing the friction between the film roll and the flipping gripper 6, ensuring that the film roll and the flipping gripper 6 remain relatively stationary during the subsequent flipping process of the film roll and do not slip. When the position sensing mechanism 66 senses that the pressing plate 622 has moved into place, it indicates that the two positioning round heads 65 clamp the two small plugs 691 (i.e., the flipping gripper 6 clamps both ends of the film roll), and the flipping gripper 6 successfully grabs the film roll. Then the film roll is moved away from the transport trolley and towards the palletizing station. During the movement, the flipping driving device 63 drives the positioning rotating shaft 62 and the pressing plate 622 to rotate, thereby driving the film roll to complete a 90° flip, so that the strapping band located between the two vertical clamping plates is flipped from the original top and bottom of the vertical clamping plate to the left and right sides of the vertical clamping plate, avoiding damage and disconnection of the strapping band due to extrusion during palletizing. Finally, the film roll is placed at the palletizing station, and the two flipping grippers 6 move away from each other to release the film roll.

[0032] If the film roll is suspended and packaged with a large plug 692 (the diameter of the plug is 6 inches), the positioning round head 65 is snapped into the center of the large plug 692, and the large plug 692 is sleeved on the positioning round head 65. The positioning round head 65 plays a supporting role for the large plug 692, and the retaining edge 652 of the positioning round head 65 abuts against the peripheral edge protrusion of the large plug 692. As the flipping gripper 6 continues to move towards the center of the film roll, the elastic limiting mechanism 67 provides a thrust to the positioning round head 65, so that the retaining edge 652 of the positioning round head 65 is always pressed against the peripheral edge protrusion of the large plug 692 during the process of the pressing plate 622 gradually approaching the positioning round head 65. At the same time, all the flipping anti-slip components 68 are pressed against the vertical clamping plate, increasing the friction force between the film roll and the flipping gripper 6, ensuring that the film roll and the flipping gripper 6 remain relatively stationary during the subsequent flipping process and do not slip. When the in-place sensing mechanism 66 senses that the positioning round head 65 has moved in place, it means that the two positioning round heads 65 clamp the two large plugs 692 (that is, the flipping gripper 6 clamps both ends of the film roll), and the flipping gripper 6 successfully grabs the film roll. Then, the film roll is moved away from the transport trolley and towards the palletizing station. During the movement, the flipping drive device 63 drives the positioning rotating shaft 62 and the pressing plate 622 to rotate, thereby driving the film roll to complete a 90° flip, so that the strapping band located between the two vertical clamping plates is flipped from the original top and bottom of the vertical clamping plate to the left and right sides of the vertical clamping plate, avoiding damage and disconnection of the strapping band due to extrusion during palletizing. Finally, the film roll is placed at the palletizing station, and the two flipping grippers 6 move away from each other and release the film roll.

[0033] Specifically, the elastic limiting mechanism 67 includes a first guide sleeve 671 fixedly arranged on the pressing plate 622, a first guide rod 672 slidably connected with the first guide sleeve 671, and a first spring 673 sleeved on the first guide rod 672. The first guide sleeve 671 is arranged on the end face of the pressing plate 622 facing the positioning round head 65. One end of the first spring 673 abuts against the first guide sleeve 671, and the other end abuts against the positioning round head 65. The first guide rod 672 passes through the pressing plate 622. One end of the first guide rod 672 is fixedly connected with the positioning round head 65, and the other end limits the first guide rod 672 to break away from the pressing plate 622. In the normal state, the first spring 673 is expanded, keeping the maximum distance between the positioning round head 65 and the pressing plate 622. The limiting circular plate restricts the first guide rod 672 from breaking away from the pressing plate 622. When the positioning round head 65 is squeezed by the plug, the positioning round head 65 moves towards the pressing plate 622, and the first spring 673 is gradually compressed, applying an elastic thrust to the positioning round head 65 to ensure that the two positioning round heads 65 can clamp the film roll.

[0034] In this embodiment, a plurality of elastic limiting mechanisms 67 are provided and are reasonably arranged between the positioning round head 65 and the pressing plate 622. On the one hand, it ensures that the forces on each part of the positioning round head 65 are evenly distributed, and on the other hand, it ensures that the clamping force of the positioning round head 65 on the wound film is sufficient, ensuring that the film roll will not shift or become loose during the movement and flipping processes.

[0035] Furthermore, the flipping anti-slip assembly 68 includes a second guide sleeve 681 fixedly arranged on the pressing plate 622, a second guide rod 682 slidably connected to the second guide sleeve 681, and a second spring 683 sleeved on the second guide rod 682. The second guide rod 682 passes through the pressing plate 622. One end of the second guide rod 682 is provided with a pressing head 684, and the other end limits the second guide rod 682 from detaching from the pressing plate 622. Dense spikes 685 are arranged on the pressing head 684. One end of the second spring 683 abuts against the second guide sleeve 681, and the other end abuts against the pressing head 684. Under the elastic force of the second spring 683, the spikes 685 on the pressing head 684 penetrate into the wooden vertical clamping plate, forming a good gripping force. Compared with setting an anti-slip gasket on the pressing head 684, it can better improve the anti-slip performance of the film roll during flipping; in addition, the second guide rod 682, the pressing head 684, and the spikes 685 can be integrally formed by casting, which is strong and durable and not easily deformed.

[0036] Preferably, the end of the positioning rotating shaft 62 away from the flipping driving device 63 is of a truncated cone structure; by such a setting, a guiding conical surface 621 can be formed on the positioning rotating shaft 62, and the guiding conical surface 621 guides the positioning rotating shaft 62 to insert into the small plug 691, reducing the assembly difficulty and ensuring that the positioning rotating shaft 62 can be smoothly inserted into the small plug 691. The positioning round head 65 includes a round head main body 651 with a hollow structure and a retaining edge 652 arranged on the peripheral wall of the round head main body 651. The middle part of the round head main body 651 is slidably connected to the positioning rotating shaft 62, the peripheral wall of the round head main body 651 cooperates with the inner wall of the large plug 692, and the retaining edge 652 fits with the peripheral edge protrusion of the large plug 692 to form an axial positioning for the large plug 692.

[0037] Preferably, a plug anti-detachment structure 64 is provided on the pressure plate 622, and the plug anti-detachment structure 64 includes a third guide sleeve 641 fixed on the pressure plate 622, a third guide rod 642 slidably connected to the third guide sleeve 641, and a third spring 644 sleeved on the third guide rod 642, the third guide rod 642 passes through the pressure plate 622, one end of the third guide rod 642 is provided with a head 643 for supporting the large plug 692, and the other end limits the third guide rod 642 from detaching from the pressure plate 622, one end of the third spring 644 presses on the third guide sleeve 641, and the other end presses on the head 643. When the flip gripper 6 grabs the film roll, the positioning shaft 62 is tightly connected to the small plug 691. Similarly, the positioning round head 65 is tightly connected to the large plug 692. The positioning shaft 62 and the positioning round head 65 can easily bring the plug away from the roll core when the plug is pulled out. Under the elastic force of the third spring 644, the top head 643 always pushes the edge protrusion of the plug to the end of the film roll, thereby fixing the plug to prevent the positioning shaft 62 and the positioning round head 65 from bringing the plug away from the roll core under the action of friction during the process of pulling out the film roll.

[0038] Specifically, the flip driving device 63 includes a first motor bracket 631 fixedly connected to the suspension bracket 61 and a flip driving motor 632 disposed on the first motor bracket 631, and the output end of the flip driving motor 632 is connected to the positioning shaft 62 through a coupling. That is, the driving motor 632 drives the positioning shaft 62 and the pressing plate 622 to rotate through the coupling, so that the suspension packaging film roll sandwiched between the two pressing plates 622 is flipped 90 degrees. In order to ensure the accuracy of the flipping angle, the coupling is provided with four flip-in-place contacts 633 arranged in a circular array, and the motor bracket 631 is provided with a flip sensor 634. The flip sensor 634 is electrically connected to the control system. Every time the driving motor 632 drives the positioning shaft 62 to rotate 90°, a flip-in-place contact 633 will trigger the flip sensor 634. The driving motor 632 drives the positioning shaft 62 to rotate unidirectionally. In the initial state, the pressure plate 622 is in a horizontal state. When the pressure plate 622 flips 90° and becomes vertical, the pressure plate 622 can be reset to the initial state by flipping another 90°, which is convenient for control.

[0039] Further, the lifting frame 4 includes a door-shaped frame body and a support beam fixedly connected to the bottom end of the door-shaped frame body, the support beam extends in the left-right direction, each of the grabbing drive mechanisms 7 corresponds to a flip gripper 6, and the grabbing drive mechanism 7 includes a grabbing drive motor arranged on the support beam, a first screw rod extending in the left-right direction and connected to the grabbing drive motor in a transmission manner, and a first screw rod nut sleeved on the first screw rod; the first screw rod nut is fixed on the suspension bracket 61. The grabbing drive motor drives the first screw rod nut on the first screw rod to move through forward and reverse motion, thereby driving the flip gripper 6 to approach or move away from the film roll, with high movement accuracy and good grabbing reliability.

[0040] Since the flipping gripper 6 is applicable to gripping film rolls of all models, and film rolls of different models have different lengths, by arranging a ranging probe 664 on the suspension bracket 61, the flipping gripper 6 can quickly move towards the end of the film roll, shortening the gripping time. When the ranging probe 664 detects that the distance between it and the film roll conforms to the set distance, it indicates that the flipping gripper 6 is very close to the film roll, and then the flipping gripper 6 moves slowly to ensure that the flipping gripper 6 can successfully grip the film roll.

[0041] In this embodiment, the carriage 2 is a U-shaped frame with an avoidance opening, the lifting frame 4 is a portal structure, and the lifting frame 4 passes through the avoidance opening on the carriage 2. At least two first guide rails 41 extending vertically are arranged on the front end face and / or the rear end face of the lifting frame 4, and a support 42 is arranged on the carriage 2, and a first slider 43 slidably connected to the first guide rail 41 is fixedly arranged on the support; through the connection of the first guide rail and the first slider, it is ensured that the lifting frame 4 can only move smoothly in the vertical direction to avoid tilting. The first guide rail, the first slider, and the support are preferably arranged in two groups to improve the reliability of the sliding of the lifting frame 4.

[0042] Preferably, the lifting drive assembly 5 includes a fixed frame, a lifting drive motor 51 arranged on the top of the fixed frame, a second lead screw 52 that is vertical and is in transmission connection with the lifting drive motor 51, and a second lead screw nut sleeved on the second lead screw; the second lead screw nut is fixed on the lifting frame 4. The lifting drive motor 51 drives the lifting frame 4 to move up and down through the transmission of the second lead screw 52 and the second lead screw nut. Due to the high transmission stability of the lead screw structure, the lifting frame 4 and the flipping gripper 6 can move smoothly and accurately move to the predetermined position.

[0043] Specifically, the vertical frame 1 includes a pillar and a cross beam arranged on the top of the pillar. The cross beam extends in the front-rear direction, and a second guide rail extending in the front-rear direction is arranged on the cross beam. The bottom of the carriage 2 is slidably connected to the second guide rail through a second slider, and the bottom of the carriage 2 is slidably connected to the second guide rail through a second slider, so that the carriage 2 can move smoothly in the front-rear direction.

[0044] Furthermore, the front-rear drive assembly 3 includes a first synchronous pulley and a second synchronous pulley rotatably arranged on the cross beam, a second motor bracket arranged on the cross beam, and a moving drive motor arranged on the second motor bracket. The first synchronous pulley and the second synchronous pulley are in transmission connection through a synchronous belt. The output end of the moving drive motor is in drive connection with the first synchronous pulley, and the carriage 2 is fixedly connected to the synchronous belt through a chuck. The moving drive motor drives the first synchronous pulley to rotate, drives the synchronous belt and the second synchronous pulley to move, and enables the synchronous belt to pull the carriage 2 to move back and forth.
