Description

Technical Field

[0001] The utility model belongs to the technical field of bundling devices, and particularly relates to a film roll suspension packaging and bundling device. Background Art

[0002] In order to protect the integrity of the coil during transportation and reduce wear, etc., it is necessary to carry out suspension packaging for the film roll. For example, in the suspension packaging process, the surface of the coil is covered with bubble film, and then the two ends are buckled with a paper cover and a foam pad and fixed by tape winding; then vertical clamping plates are installed at both ends of the coil, and then the two vertical clamping plates are bundled, so that the coil is suspended between the two vertical clamping plates. In some production enterprises, the bundling process still requires manual control of the crane to lift the coil to the packaging machine, and the vertical clamping plates are bundled by the packaging machine. After the bundling is completed, the coil is lifted off the packaging machine. The work efficiency is low and the degree of automation is low. And some automated equipment has the situation of ultra-high design height due to the need for lifting, which has requirements for the height of the factory building design, and the center of gravity is relatively high, resulting in shaking, instability and high energy consumption after the mechanism runs. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a film roll suspension packaging and bundling device to solve the problems of too high height, instability and high energy consumption in the prior art solutions.

[0004] According to the technical solution of the utility model, the utility model provides a film roll suspension packaging and bundling device, which includes a first rack. The first rack has a cross beam arranged in the front-rear direction. A moving frame is connected to the cross beam through a front-rear moving mechanism. Second racks are fixedly arranged at the left and right ends of the moving frame. A longitudinal lifting and moving mechanism is arranged on the second racks. A bundling machine module is arranged between the lifting and moving mechanisms. The bundling machine module includes a tape running frame and a bundling machine head arranged on the tape running frame. The tape running frame is connected to the lifting and moving mechanism.

[0005] Further, the moving frame is of a frame structure with a vertically through middle part; the lifting and moving mechanism longitudinally penetrates through the middle part of the moving frame, and the top of the lifting and moving mechanism is connected to the second rack.

[0006] Further, the lifting and moving mechanism includes a lead screw and a lifting drive motor. The lifting drive motor is arranged at the end of the lead screw. The lead screw is longitudinally arranged and perpendicular to the moving frame, and the lead screw is rotationally connected to the moving frame and / or the second rack.

[0007] Further, the lifting and moving mechanism further includes a bundling connection slider. The bundling connection slider is provided with a longitudinally through threaded hole. The lead screw penetrates into the threaded hole and is threadedly connected in a matching manner. The bundling connection slider is connected to the tape running frame.

[0008] Further, the front-back moving mechanism includes a synchronous pulley rotatably arranged on the cross beam and a front-back moving drive motor arranged on the cross beam; the synchronous pulley is drivingly connected with a transmission belt, the output end of the front-back moving drive motor is drivingly connected with the synchronous pulley, and the moving frame is connected with the transmission belt.

[0009] Further, the bundling head includes a machine shell, a belt pulling assembly, a belt conveying assembly, a belt pressing assembly, a heat sealing assembly, and a cutter for cutting the bundling belt; the belt pulling assembly is located on one side of the belt conveying assembly, and the belt pressing assembly and the heat sealing assembly are located on the other side of the belt conveying assembly and at the break of the belt running frame.

[0010] Further, the cross beam is an I-shaped steel. Two synchronous pulleys are arranged on each cross beam and are respectively located at the front and rear ends of the cross beam. Each synchronous pulley is respectively connected with a front-back moving drive motor, and the two front-back moving drive motors jointly drive the moving frame to move back and forth.

[0011] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0012] 1. The overall height is significantly reduced. The lifting and moving mechanism is driven by a lead screw. The lead screw drives the bundling connection slider to move up and down to realize the movement of the belt running frame within the stroke range of the lead screw, reducing the total height of the mechanism. The height is changed from more than seven meters of the original device to more than five meters now to meet the height requirements of most factories.

[0013] 2. The center of gravity position of the existing device is too high, resulting in shaking after the mechanism operates. After improvement, the center of gravity position is well stressed and the stability is improved; and by adopting the lead screw method, the bundling connection slider is provided with a vertically penetrating threaded hole, and the lead screw penetrates into the threaded hole and is threadedly connected in a matching manner, further making the mechanism not shake significantly after operation, and the operation and load-bearing effects are stable and reliable.

[0014] 3. The energy consumption is reduced. When the existing device is lifted, it is necessary to lift a very heavy bundling machine and the frame structure together, which requires a large amount of energy consumption; after improvement, only the bundling connection slider and the bundling machine module need to be lifted, and the rest of the weight is borne by the machine frame, and the energy consumption is greatly reduced.

[0021] The utility model provides a film roll suspension packaging and strapping device, which solves the problems of too high height, instability and high energy consumption in the prior art solutions. This solution mainly sets a first rack and a cross beam arranged in the front and rear directions. A moving frame is connected to the cross beam through a front and rear moving mechanism. Second racks are fixedly arranged at both ends of the moving frame. A set of lifting and moving mechanisms perpendicular to the moving frame are longitudinally arranged on the second racks. A strapping machine module is arranged between the lifting and moving mechanisms. The strapping machine module includes a tape running frame and a strapping head arranged outside the tape running frame. The tape running frame is fixedly connected to the lifting and moving mechanism, thereby realizing suspended automatic strapping.

[0022] Please refer to Figure 1 , Figure 3 , in an embodiment of the utility model, a film roll suspension packaging and strapping device includes a first rack 1. The first rack 1 has two cross beams 11 arranged in the front and rear directions. A moving frame 3 is connected to the cross beam 11 through a front and rear moving mechanism 2. Second racks 4 are fixedly arranged at the left and right ends of the moving frame 3. A longitudinal and downward extending lifting and moving mechanism 5 is arranged on the second racks 4. A strapping machine module 6 is arranged between the lifting and moving mechanisms 5. The lifting and moving mechanism 5 is used to drive the strapping machine module 6 to move up and down within a range not exceeding the height of the second rack 4. The strapping machine module 6 can move up and down along the lifting and moving mechanism 5 and move back and forth along with the moving frame 3. The strapping machine module 6 mainly includes a tape running frame 61 and a strapping head 62 arranged outside the tape running frame 61. The tape running frame 61 is connected to the lifting and moving mechanism 5. The strapping head 62 is used to cooperate with the tape running frame 61 to strap the film roll in the tape running frame 61. The tape running frame 61 is stably connected to the lifting and moving mechanism 5 through the strapping connection sliders 53 arranged on both sides of the tape running frame 61. Due to the setting of the second rack 4 and the lifting and moving mechanism 5 in this solution, it is realized that the overall height of the device remains unchanged during the lifting process of the strapping machine module 6 and can always be maintained at a relatively low level, which can meet the conditions of most factories.

[0023] More specifically, please refer to Figure 2The movable frame 3 is a frame-shaped structure, for example, a rectangular structure spanning across two cross beams 11, and the middle part of the movable frame 3 is vertically penetrated (in other words, it has a through hole / avoidance space). The lifting and moving mechanism 5 longitudinally penetrates the middle part of the movable frame 3, and the top of the lifting and moving mechanism 5 is connected to the second frame 4. The lifting and moving mechanism 5 includes a screw rod 51 and a lifting drive motor 52, and the lifting drive motor 52 is arranged at the end of the screw rod 51. The screw rod 51 is longitudinally arranged and perpendicular to the movable frame 3, and the screw rod 51 is rotatably connected to the movable frame 3 and / or the second frame 4, for example, connected by a bearing, so that the screw rod 51 can rotate in situ under the drive of the lifting drive motor 52. The lifting and moving mechanism 5 also includes a bundling connection slider 53, and the bundling connection slider 53 is provided with a longitudinally through threaded hole, and the screw rod 51 is inserted into the threaded hole and threadedly connected in a matching manner, and the bundling connection slider 53 is connected to the tape walking frame 61. The lifting mechanism 5 has a longitudinal lifting rail 54 on the side, and the bundling connection slider 53 is slidably connected to the lifting rail 54. Thus, the bundling connection slider 53 can drive the bundling machine module 6 to move up and down under the rotation of the screw rod 51. This solution is driven by a screw rod, which can provide sufficient tension in the longitudinal direction, thereby ensuring the connection stability of the relatively heavy bundling machine module.

[0024] Preferably, if Figure 2 As shown, the lifting and moving mechanism 5 includes two vertical frames, the screw rod 51 is located between the two vertical frames, the lifting slide rail 54 is located on the opposite sides of the two lifting and moving mechanisms 5 on the two cross beams 11, and there are two side-by-side lifting slide rails 54 in one lifting and moving mechanism 5; this preferred solution has a compact structure and stable lifting. More preferably, the second frame 4 is arranged above the moving frame 3, so that the space between the second frame 4 and the moving frame 3 can be used, so that the strapping machine module 6 can reach the required height and is not limited by the height of the first frame 1, which is easy to match with the overall frame structure of the suspension packaging system, and also helps to improve space utilization.

[0025] See also Figure 4, In a preferred embodiment, the front and rear movement mechanism 2 includes synchronous belt pulleys 21 rotatably arranged on the cross beam 11, for example, there are two synchronous belt pulleys 21 arranged at the front and rear ends of the cross beam 11; it further includes a front and rear movement driving motor 22 arranged on the cross beam 11. The synchronous belt pulleys 21 are drivingly connected with a transmission belt 23, the output end of the front and rear movement driving motor 22 is drivingly connected with the synchronous belt pulley 21, and the length direction of the transmission belt 23 is consistent with the length direction of the cross beam 11. The left and right ends of the moving frame 3 are respectively fixedly connected to a horizontal section of the transmission belts 23 on the left and right sides through, for example, clamping heads; thus, the front and rear movement driving motor 22 drives the transmission belt 23 to move, and the part of the transmission belt 23 between the front and rear synchronous belt pulleys 21 generates a translational movement, providing driving control for the front and rear movement of the moving frame 3. In addition, a front and rear slide rail 24 is arranged above the cross beam 11 along the length direction, and the lower parts of the left and right ends of the moving frame 3 are provided with front and rear sliders so as to be slidably connected with the front and rear slide rails 24 in a matching manner. It can be understood that according to other embodiments, the driving for the front and rear movement of the moving frame 3 can also be selected as other methods such as a gear rack or a lead screw, etc.

[0026] Further preferably, the cross beam 11 is an I-shaped steel, and the synchronous belt pulleys 21 can be installed in the I-shaped steel grooves, making the structure more compact. Two synchronous belt pulleys 21 are arranged on each cross beam 11 and are respectively located at the front and rear ends of the cross beam 11, and each synchronous belt pulley 21 is respectively connected with a front and rear movement driving motor 22. The two front and rear movement driving motors 22 jointly drive the moving frame 3 to move back and forth, ensuring sufficient traction force and improving the movement efficiency and reliability of the front and rear movement mechanism 2. In addition, preferably, a drag chain structure is also provided, which can neatly store the wires in the drag chain, effectively preventing the wires from being broken or loosened, and avoiding interference with other components.

[0027] Please refer to Figure 3, preferably, the strapping head 62 includes a housing, a strap pulling assembly, a belt conveying assembly, a belt pressing assembly, a heat sealing assembly, and a cutter for cutting the strapping tape; the strap pulling assembly is located on one side of the belt conveying assembly, and the belt pressing assembly and the heat sealing assembly are located on the other side of the belt conveying assembly and at the break of the tape running frame 61; the belt conveying assembly is used to convey the packing tape into the tape running frame 61. After the head of the strapping tape goes around the tape running frame 61, the belt conveying assembly takes in the tape and then the strap pulling assembly tightens the packing tape; the belt pressing assembly is used to press the strapping tape and the head of the strapping tape before heat sealing, and the heat sealing assembly is used to heat seal the strapping tape and the head of the strapping tape. The strapping tape first passes through the strap pulling assembly and then enters the belt conveying assembly. The strapping tape is conveyed by the belt conveying assembly and enters the tape running frame 61, and then goes around the tape running channel of the tape running frame 61. When the head of the strapping tape is transmitted to the heat sealing assembly, the belt conveying assembly stops feeding the tape. The belt pressing assembly presses the strapping tape onto the head of the strapping tape, and then the belt conveying assembly takes in the tape backward, and then the strap pulling assembly tightens the strapping tape to tightly bind the splints. Then, the heat sealing assembly heat-seals the strapping tape and the head of the strapping tape, so that the strapping tape and the head are firmly bonded. It should be noted that the specific structures of the strap pulling assembly, the belt conveying assembly, the belt pressing assembly, the heat sealing assembly, and the cutter can adopt the existing technologies, which will not be elaborated here.

[0028] According to some embodiments, the strapping device of the present solution has the following working process. Upstream of the suspended packaging strapping device, there is a device for respectively installing two splints at both ends of the coil. After the upper splints are installed on both sides of the coil, the coil is transported to the strapping station by a transfer trolley to achieve suspended strapping. At this time, the tape running frame is lifted to the highest position (i.e., the initial position) by the lifting and moving mechanism, and the coil is located directly below the tape running frame to avoid collision with the coil. Then, the front and rear moving mechanism drives the moving frame and the components on the moving frame to move in front of the coil. Subsequently, the lifting and moving mechanism drives the tape running frame to descend to an appropriate height according to the diameter of the coil. Then, the front and rear moving mechanism drives the tape running frame to move backward, so that the front ends of the two splints pass through the tape running frame. The strapping head is used to draw the strapping tape into the tape running frame. After the strapping tape goes around the tape running frame, the overlapping part of the strapping tape and the head of the strapping tape is butted, and the strapping tape is pulled back, so that the strapping tape tightly binds the two splints. Then, the strapping head heat-seals the overlapping part of the strapping tape and the head of the strapping tape, and finally cuts the strapping tape to complete the automatic strapping on the front side of the coil. To further improve the reliability of strapping, the lifting and moving mechanism drives the tape running frame to reset to the initial position. Then, the front and rear moving mechanism drives the moving frame and the components on the moving frame to the rear of the coil. Subsequently, the lifting and moving mechanism drives the tape running frame to descend to an appropriate height according to the diameter of the coil. Then, the front and rear moving mechanism drives the tape running frame to move forward, so that the rear ends of the two splints pass through the tape running frame, and the strapping head performs automatic strapping on the rear side of the coil. After the coil is strapped on the front and rear sides, it is ensured that the splints are closely attached to the coil, avoiding the splints from detaching from the coil, and keeping the splints in a vertical state during subsequent handling to ensure the stability of palletizing.

[0029] In summary, compared with the existing structure, the utility model has the characteristics of high automation degree, as well as the advantages of high adaptability to the height of the factory building, low center of gravity, good stability and high economy, which are specifically as follows:

[0030] 1. The overall height is significantly reduced: the height of the device is changed from more than seven meters to more than five meters, so as to meet the height requirements of most factory buildings.

[0031] 2. The stability is significantly improved: previously, the center of gravity of the mechanism was too high, which caused the mechanism to shake after operation. After improvement, the center of gravity position is lowered, the force is well distributed, and the stability is improved.

[0032] 3. The energy consumption is significantly reduced: previously, when the mechanism was lifted, a very heavy bundling machine and the frame (or called the arm) structure needed to be lifted together, which required a large amount of energy consumption. After improvement, only the bundling connection slider and the bundling machine module need to be lifted, and the remaining weight is borne by the machine frame, so the energy consumption is greatly reduced.
