An outer tube extending horizontally is provided on the casing, and an inner tube slidably connected thereto is inserted into the outer tube. One end of the inner tube is fixedly connected to the pressure plate. A first wire passing hole communicating with the inside of the inner tube is opened at one end of the inner tube close to the pressure plate, and a second wire passing hole communicating with the inside of the inner tube is opened at one end of the outer tube away from the pressure plate.

[0008] As a further improvement of the above technical solution, a connector is provided at one end of the pressure sensor facing the pressure plate, and the connector is pivotally connected to the pressure plate.

[0009] As a further improvement of the above technical solution, at least one set of guiding assemblies is provided on the casing.

Next, the three-axis drive structure drives the tape running frame to move backward, so that the front ends of the two vertical clamping plates pass through the tape running frame. The bundling head is used to pull the bundling tape into the tape running frame. After the bundling tape goes around the tape running frame, the overlapping part of the bundling tape and the bundling tape head is butted, and the bundling tape is pulled back, so that the bundling tape tightly binds the two vertical clamping plates. The bundling head performs heat sealing on the overlapping part of the bundling tape and the bundling tape head, and finally cuts the bundling tape to complete the automatic bundling of the front side of the coil, saving labor and promoting the automatic improvement of the coil suspension packaging industry.

Detailed implementation manners

[0027] The present invention provides a floating film roll strapping device. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following further details the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0028] Please refer to Figure 1 and Figure 2 The present invention provides a floating film roll strapping device, including a transport trolley 1 for carrying film rolls, two vertical frames 2, a three-axis drive structure arranged on the vertical frames 2, a tape running frame 3 arranged on the three-axis drive structure, a strapping head 4 arranged outside the tape running bundle, and a tape storage assembly 9 for providing strapping tapes for the strapping head 4 and the tape running frame 3. A strapping station 6 is provided between the two vertical frames 2. The strapping head 4 is used to cooperate with the tape running frame 3 to strap the items in the tape running frame 3. A centering and clamping mechanism 7 for pushing two vertical clamping plates 12 to clamp the film roll 11 is arranged on the two vertical frames 2.

[0029] The upstream of the suspension bundling device is provided with a device for installing two vertical clamping plates 12 at both ends of the film roll respectively. After the film roll 11 is installed with the vertical clamping plates 12, the film roll 11 is transported to the bundling station 6 by the transport trolley 1 to realize suspension bundling, and then the centering clamping mechanism 7 pushes the film roll to the center position and pushes the two vertical clamping plates 12 to clamp the ends of the film roll 11. At this time, the tape frame 3 is lifted to the highest position (i.e., the initial position) by the three-axis drive structure, and the film roll 11 is located directly below the tape frame 3. Figure 5 As shown in the figure, in order to avoid collision with the film roll, the three-axis driving structure first drives the tape frame 3 to move to the front of the film roll, and then the three-axis driving structure drives the tape frame 3 to drop to an appropriate height according to the diameter of the film roll, and then the three-axis driving structure drives the tape frame 3 to move backward, so that the front end portions of the two vertical clamps 12 pass through the tape frame 3, and the strapping machine head 4 is used to pull the strapping belt into the tape frame 3. After the strapping belt has walked a circle along the tape frame 3, the overlapping part of the strapping belt and the strapping belt head is butted, and the strapping belt is pulled back so that the strapping belt is tightly bound around the two vertical clamps 12, and the overlapping part of the strapping belt and the strapping belt head is butted and heat-sealed by the strapping machine head 4, and finally the strapping belt is cut off to complete the automated strapping of the front side of the film roll.

[0030] In order to further improve the reliability of bundling, the three-axis drive structure will reset to the initial position, and then the three-axis drive structure will drive the tape frame to the rear of the film roll, and then the three-axis drive structure will drive the tape frame 3 to drop to an appropriate height, and then the three-axis drive structure will drive the tape frame 3 forward, so that the rear ends of the two vertical clamps 12 pass through the tape frame 3, and the strapping machine head 4 will automatically strap the rear side of the film roll. After the film roll is strapped on the front and back sides, the vertical clamps 12 are ensured to be close to the film roll 11 to prevent the vertical clamps 12 from detaching from the film roll 11. Finally, the centering clamping mechanism 7 releases the film roll, and the transport trolley 1 moves the strapped film roll away from the strapping station 6, and the transportation process is smooth.

[0031] For details, please refer to Figures 3 - 5The centering clamping mechanism 7 includes two clamping assemblies 71 symmetrically arranged on the corresponding stand 2, each clamping assembly 71 includes a housing 711 fixedly connected to the stand 2, an electric push rod 712 arranged on the housing 711, and a pressure plate 713 vertically arranged on one side of the housing 711; a pressure sensor 714 is arranged at the output end of the electric push rod 712, and the pressure sensor 714 is transmission-connected with the pressure plate 713, and the electric push rod 712 is used to drive the pressure sensor 714 and the pressure plate 713 to reciprocate laterally. When the two ends of the film roll are installed with the vertical clamping plates 713, the film roll is transported to the bundling station 6. At this time, the two clamping assemblies 71 work synchronously and automatically. Each of the electric push rods 712 drives the pressure plate 713 to move in the direction of the vertical clamping plates 12. The two pressure plates 713 jointly push the film roll 11 to move, so that the film roll is centered. During the pushing process, the vertical clamping plates generate a reaction force on the pressure plates 713. At this time, the pressure sensor 714 can feedback the value of the reaction force to the control system. Since the reaction force value preset by the control system is large (such as 50N), after the film roll is centered, the two pressure plates 713 continue to press the vertical clamping plates on the film roll, and then the reaction force gradually increases until the reaction force value fed back by the pressure sensor 714 is equal to the preset value, which means that the pressure plate 713 firmly presses the vertical clamping plates on the end of the film roll. The control system controls the electric push rod 712 to stop moving, and the two vertical clamping plates clamp the film roll together to ensure that the strapping belt is tighter and more secure when tying the two vertical clamping plates.

[0032] Further, a wiring assembly 72 for routing wires of the pressure sensor 714 is provided on the housing 711. An outer tube 721 extending horizontally is provided on the housing 711. An inner tube 722 slidably connected thereto is inserted into the outer tube 721. One end of the inner tube 722 is fixedly connected to the pressing plate 713. A first wire passing hole 723 communicating with the inside of the inner tube 722 is formed at one end of the inner tube 722 close to the pressing plate 713. A second wire passing hole 724 communicating with the inside of the inner tube 722 is formed at one end of the outer tube 721 away from the pressing plate 713. A surrounding cover is provided on the housing 711, and a third wire passing hole 725 is formed in the housing 711. The power supply wire and the signal transmission wire of the pressure sensor 714 enter the inner tube 722 through the first wire passing hole 723, then enter the inner cavity of the outer tube 721 through the second wire passing hole 724, and finally are electrically connected to an external control system through the third wire passing hole 725. The inner tube 722 and the outer tube 721 standardize the moving area of the power supply wire and the signal transmission wire, avoiding interference with other components. Since the inner tube 722 moves with the pressing plate 713, the distance between the first wire passing hole 723 and the pressure sensor 714 is always equal, and the power supply wire and the signal transmission wire located between the first wire passing hole 723 and the pressure sensor 714 do not change, preventing the connection between the power supply wire and the signal transmission wire and the pressure sensor 714 from being torn off. The power supply wire and the signal transmission wire located in the inner tube 722 and the outer tube 721 stretch or contract as the inner tube 722 slides, ensuring the neat routing of the wires of the pressure sensor 714.

[0033] Furthermore, a joint 73 is provided at one end of the pressure sensor 714 facing the pressing plate 713, and the joint 73 is pivotally connected to the pressing plate 713. During actual assembly, it is required that the electric push rod 712 be installed horizontally to provide a horizontal thrust. However, if the electric push rod 712 is slightly inclined during the assembly process, the pressing plate 713 can still automatically adjust to a vertical state without interference, greatly reducing the assembly difficulty.

[0034] Preferably, at least one set of guiding assemblies 74 is provided on the housing 711. Each guiding assembly 74 includes a horizontally extending sleeve 741 fixedly provided and a guide rod 742 slidably inserted into the sleeve 741. One end of the guide rod 742 is fixedly connected to the pressing plate 713. The guide rod 742 can not only guide the movement of the pressing plate 713 to ensure that the pressing plate 713 always remains in a vertical state, but also limit the pressing plate 713 to avoid the joint 73 from being deformed by tangential force. In this embodiment, two sets of guiding assemblies 74 are provided, and the two sets of guiding assemblies 74 are respectively located on the upper and lower sides of the electric push rod 712.

[0035] Preferably, a plurality of rubber blocks 75 are provided on the end surface of the pressing plate 713 facing away from the electric push rod 712, and the plurality of rubber blocks 75 are arranged at intervals in the vertical direction and evenly arranged on the pressing plate 713. The rubber blocks 75 are deformed and pressed on the pressing plate 713. Compared with the direct rigid contact between the pressing plate 713 and the vertical clamping plate 12, the rubber blocks 75 have better wear resistance and deformability, which can protect the vertical clamping plate on the one hand, and can make the vertical clamping plate more evenly stressed on the other hand, thereby improving the clamping effect.

[0036] For details, please refer to Figures 6 - 9 The three-axis driving structure includes a slide 81 that spans across the two upright frames 2 and is slidably arranged on the two upright frames 2, a front-rear driving component 82 for driving the slide 81 to move forward and backward, a lifting frame 83 that is slidably arranged on the slide 81, and a lifting driving component 84 for driving the lifting frame 83 to move up and down. The strapping process is briefly described as follows: after the coil is conveyed to the strapping station 6, the front and rear drive components 82 drive the slide 81 and the components on the slide 81 to move to the front of the coil, and then the lifting drive component 84 drives the tape frame 3 to descend to an appropriate height according to the diameter of the coil. Then the front and rear drive components 82 drive the tape frame 3 to move backward, so that the front ends of the two vertical clamps pass through the tape frame 3, and the strapping machine head 4 is used to pull the strapping belt into the tape frame 3. After the strapping belt travels along the tape frame 3 for a circle, the overlapping part of the strapping belt and the strapping belt head is docked, and the strapping belt is pulled back so that the strapping belt tightly binds the two vertical clamps, and the overlapping part of the strapping belt and the strapping belt head is docked and heat-sealed by the strapping machine head 4, and finally the strapping belt is cut to complete the automated strapping of the front side of the coil. Then the lifting drive assembly 84 will reset to the initial position, and then the front and rear drive assembly 82 will drive the slide 81 and the components on the slide 81 to the rear of the coil, and then the lifting drive assembly 84 will drive the tape frame 3 to descend to a suitable height according to the diameter of the coil, and then the front and rear drive assembly 82 will drive the tape frame 3 to move forward, so that the rear ends of the two vertical clamps 12 pass through the tape frame 3, and the strapping machine head 4 will then automatically strap the rear side of the coil. After the coil is strapped on the front and rear sides, the vertical clamps are ensured to be close to the coil to prevent the vertical clamps from detaching from the coil, and the vertical clamps are kept in a vertical state at all times during subsequent transportation to ensure the stability of stacking.

[0037] In this embodiment, the slide 81 is a circular frame with an escape opening 811, the lifting frame 83 is a door-shaped structure, the tape transport frame 3 is fixedly connected to the root of the lifting frame 83, and the lifting frame 83 passes through the escape opening 811 on the slide 81. In order to install the lifting frame 83 on the slide 81, at least two vertically extending first guide rails (not visible in the figure) are arranged on the front end face and / or the rear end face of the lifting frame 83, and the slide 81 is provided with a support 831, and the support 831 is fixedly provided with a first slider 832 slidably connected to the first guide rail. Through the connection between the first guide rail and the first slider 832, it is ensured that the lifting frame 83 can only move smoothly in the vertical direction to avoid tilting. The first guide rail, the first slider 832 and the support 831 are preferably arranged in two groups to improve the reliability of the sliding of the lifting frame 83.

[0038] Preferably, the lifting drive assembly 84 includes a rack 841 vertically arranged on any side of the lifting frame 83, a first motor bracket 842 arranged on the slide 81, and a lifting drive motor 843 arranged on the first motor bracket 842; a gear 844 is arranged on the output end of the lifting drive motor 843, and the gear 844 is meshed with the rack 841 for transmission. The lifting drive motor 843 drives the lifting frame 83 and the tape transport frame 3 to move up and down through the transmission of the rack 841 and the gear 844. Since the transmission stability of the gear 844 and the rack 841 is relatively high, the tape transport frame 3 can move smoothly and accurately to a predetermined position.

[0039] Specifically, the stand 2 includes a pillar 21 and a crossbeam 22 arranged on the top of the pillar 21, the crossbeam 22 extends in the front-to-back direction, and a second guide rail 23 extending in the front-to-back direction is arranged on the crossbeam 22.

The strapping belt first passes through the belt pulling assembly and then enters the belt conveying assembly. The strapping belt is conveyed by the belt conveying assembly and enters the belt running frame 3, and then winds around the belt running channel of the belt running frame 3. When the head of the strapping belt is transmitted to the heat sealing assembly, the belt conveying assembly stops feeding the belt. The belt pressing assembly presses the strapping belt onto the head of the strapping belt, and then the belt conveying assembly takes in the belt backward, and then the belt pulling assembly tightens the strapping belt to tightly bind the vertical clamping plate. Then, the heat sealing assembly heats and bonds the strapping belt and the head of the strapping belt, so that the strapping belt and the head are firmly bonded. It should be noted that the structures of the belt pulling assembly, the belt conveying assembly, the belt pressing assembly, the heat sealing assembly, and the cutter are prior arts and will not be elaborated here.
