Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a wrapping machine and a production line equipped with the wrapping machine. Background Technology

[0002] Currently, goods typically require packaging before leaving the factory to achieve protection, fixation, or facilitate storage and transportation. Taking common forms such as cuboid boxes, cuboid block structures, or combinations of cuboid blocks as examples, to ensure structural stability after packaging, at least one perimeter of the cuboid structure (such as the front, back, left, and right sides surrounding the outer surface of the cuboid) is usually wrapped with packing film or tape. The binding effect of the film or tape effectively prevents the goods from shifting, falling apart, or being damaged during subsequent warehousing, handling, or transportation, thereby ensuring the quality of the goods upon leaving the factory and the safety of storage and transportation.

[0003] like Figure 1 As shown, a conventional wrapping machine 9 includes a feeding mechanism 91, a support mechanism 92, and a wrapping mechanism 93. The feeding mechanism 91 includes multiple parallel rotating rollers 91, which easily move the goods to be packaged to the support mechanism 92, allowing the support mechanism 92 to support the goods. The wrapping mechanism 93 includes a rotating ring 931, a drive unit, and a roll storage unit 932. The drive unit drives the rotating ring 931 to rotate, and the roll storage unit 932 is mounted on the rotating ring 931 to follow its rotation. When the goods are fed to the support mechanism 92, they pass through the rotating ring 931. The drive unit drives the rotating ring 931 to rotate, and the tape stored in the roll storage unit 932 follows the rotating ring 931 to rotate around the circumference of the goods, thereby wrapping the tape around the circumference of the goods to achieve packaging. However, the shortcomings of this wrapping machine 9 are: First, the degree of automation in wrapping is limited. It can only wrap and package one side of the goods (such as the front, left, back, and right sides). When it is necessary to wrap and package another side of the goods (such as the front, top, back, and bottom sides), the goods need to be returned to the feeding mechanism 91, and then the position of the goods needs to be adjusted manually or by another device. The goods are then sent back to the support mechanism 92 so that the wrapping mechanism 93 can wrap and package the other side of the goods again. Secondly, the production efficiency is low. After wrapping one side of the goods, the tape wrapped around the goods and the tape roll need to be cut and separated. Then, the position of the goods can be adjusted before wrapping another side of the goods. In other words, the tape needs to be cut after one side of the goods is installed before the position of the goods can be adjusted. It is impossible to continuously wrap multiple sides of the goods without interruption. Utility Model Content

[0004] To address the aforementioned problems, the primary objective of this invention is to provide a wrapping machine that can continuously and uninterruptedly wrap multiple circumferential surfaces of goods, achieving a high degree of automation and high production efficiency.

[0005] The second objective of this invention is to provide a production line equipped with the aforementioned winding machine.

[0006] To achieve the first objective of this utility model, this utility model provides a winding machine, including a winding mechanism. The winding mechanism includes a rotating ring, a first driving unit, and a material roll storage unit. The first driving unit can drive the rotating ring to rotate. The material roll storage unit is installed on the rotating ring. The winding machine also includes a feeding mechanism, which has a receiving station and a winding station distributed along the first rotation axis of the rotating ring. The winding mechanism is located at the winding station. The feeding mechanism includes a platform, a second driving unit, and a third driving unit. The second driving unit can drive the platform to rotate. The second rotation axis of the platform is perpendicular to or intersects the first rotation axis. The third driving unit can drive the second driving unit to move between the receiving station and the winding station.

[0007] As can be seen from the above, the design of the feeding mechanism allows the feeding mechanism to transfer the goods to be packaged to the wrapping station. First, the wrapping mechanism wraps the first side of the goods with a material strip (such as packing film, tape, etc.). Then, through the cooperation of the second and third drive units, the goods are rotated at a preset angle at the wrapping station. In this way, the wrapping mechanism can directly wrap the second, third, and fourth side of the goods. At the same time, it eliminates the need to cut the material strip during the rotation and adjustment of the goods' position. This allows the wrapping mechanism to continuously and uninterruptedly wrap the material strip on each side of the goods, ensuring packaging continuity and reliability, while also improving the wrapping efficiency of the wrapping machine.

[0008] A further embodiment is that the winding mechanism also includes a cutting unit, which includes a cutting module and a first drive module, the first drive module being able to drive the cutting module to move parallel to the first rotation axis.

[0009] As can be seen from the above, the cutting unit is used to cut the material strip after the goods have been wrapped and packaged. The first drive module drives the cutting unit to move, which can effectively prevent the cutting unit from interfering with the wrapping of the material strip during the wrapping and packaging process, thus ensuring the safety and quality of the packaging.

[0010] In a preferred embodiment, the winding machine further includes a positioning mechanism located at the material receiving station. The positioning mechanism includes two positioning units distributed along a first direction, with a platform located between the two positioning units. The first direction is perpendicular to the first rotation axis. Each positioning unit includes a positioning push plate and a second drive module, which can drive the positioning push plate to move in the first direction.

[0011] As can be seen from the above, the positioning mechanism can ensure the alignment of the goods with the first rotation axis of the swivel, thereby enabling the material strip to be wound more evenly and tightly around the goods.

[0012] A further embodiment is that the feeding mechanism also includes a clamping unit, which is mounted on the second drive unit. The clamping unit includes a clamping end and a third drive module, which can drive the clamping end to move relative to the platform along the second rotation axis.

[0013] As can be seen from the above, by setting up a clamping unit, the position of the goods can be prevented from shifting during the process from being positioned to moving to the winding station, and during the winding process, while ensuring that the material strip can be reliably and tightly wound around the perimeter of the goods.

[0014] A further embodiment is that the clamping end includes a first connecting frame and a clamping member. The first connecting frame is connected to the drive end of the third drive module, and the clamping member is located between the first connecting frame and the platform. The clamping member is rotatably connected to the first connecting frame around a second rotation axis.

[0015] As can be seen from the above, this design allows the clamping component to rotate along with the platform and the goods during the rotation of the goods driven by the second drive unit via the platform. On the one hand, this prevents the position from shifting during the rotation of the goods, and on the other hand, it keeps the clamping component and the goods or material strip relatively stationary, preventing relative movement between the clamping component and the goods or material strip that could cause wear on the goods or material strip, thus improving the quality of wrapping and packaging.

[0016] A further embodiment is that the winding machine also includes a position detection mechanism, which includes a first position detection sensor and a fourth drive unit. The fourth drive unit is located on the winding mechanism and can drive the first position detection sensor to move parallel to the first rotation axis. Alternatively, the fourth drive unit is located at the winding station and can drive the first position detection sensor to move relative to the platform located at the winding station.

[0017] As can be seen from the above, the first position detection sensor is used to detect the position of the goods on the platform as they move from the receiving station to the winding station, so that the third drive unit can adjust the relative position of the goods and the winding mechanism to ensure that the material strip is reliably wound on the goods according to the set position; the fourth drive unit can adjust the position of the first position detection sensor to avoid interference between the first position detection sensor and the material strip during the winding and packaging process of the winding mechanism.

[0018] Another preferred embodiment is that the winding mechanism further includes a material preparation unit, which includes a material preparation roller and a fourth drive module. The material preparation roller is parallel to the first rotation axis and is located between the cutting module and the material roll storage unit. The fourth drive module can drive the material preparation roller to move parallel to the first rotation axis.

[0019] As can be seen from the above, the preparation roller is designed so that when the wrapping of the goods is completed and the material strip is cut, the front end of the new unwound material strip is fixed on the preparation roller, ensuring that the material strip can be tightly wrapped around the goods when wrapping the next goods. The fourth drive module is used to adjust the position of the preparation roller to avoid the preparation roller interfering with the wrapping of the material strip on the goods during the wrapping process, thus ensuring the tightness of the wrapping and the quality of the packaging.

[0020] A further proposed solution is that the material preparation unit also includes a pressure bar and a fifth drive module. The fifth drive module is connected to the drive end of the fourth drive module. The fifth drive module can drive the pressure bar to move relative to the material preparation roller, so that a clamping position is formed between the pressure bar and the material preparation roller.

[0021] As can be seen above, after the material strip is cut, the pressure bar can be moved toward the preparation roller under the drive of the fifth drive module to reliably fix the front end of the newly cut unwound material strip on the preparation roller, thereby ensuring that the material strip can be tightly wrapped around the goods when wrapping the next product.

[0022] A further embodiment includes a material roll storage unit comprising a second connecting frame, a rotating frame, a swing frame, an elastic element, and a guide roller assembly. The second connecting frame is mounted on a rotating ring, and the rotating frame is rotatably mounted on the second connecting frame. The third rotation axis of the rotating frame is parallel to the first rotation axis. The first end of the swing frame is rotatably connected to the second connecting frame, and the second end of the swing frame is provided with a pressure roller. The elastic element forces the swing frame to rotate towards the direction close to the third rotation axis. The guide roller assembly is mounted on the second connecting frame. The winding mechanism also includes a counterweight, which is mounted on the rotating ring.

[0023] As can be seen from the above, the rotating frame allows the material roll to be unwound smoothly, while the swing frame and elastic components ensure the quality of the unwinding of the material roll. The guide roller group guides the material roll, allowing it to be better wound onto the goods. The counterweight is used to adjust the mass distribution of the rotating ring, making the center of mass coincide with the first rotation axis, eliminating the imbalance of centrifugal force when the rotating ring rotates, avoiding problems such as vibration and wear, and extending the life of the winding mechanism and the winding quality of the material roll.

[0024] To achieve the second objective of this utility model, this utility model provides a production line, which includes the aforementioned winding machine.

[0025] As can be seen from the above, by setting up the aforementioned wrapping machine, the production line can achieve continuous and uninterrupted wrapping of multiple circumferences of the goods, thereby improving the degree of automation and increasing production efficiency.

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0038] Implementation Examples of Wrapping Machines Reference Figure 2 and Figure 3 The wrapping machine 100 includes a frame 1, a wrapping mechanism 2, a feeding mechanism 3, a positioning mechanism 4, a position detection mechanism 5, a lifting mechanism 6, and a control system. The frame 1 has a packaging compartment with a goods inlet / outlet. A pad 11 is provided at the goods inlet / outlet to facilitate the loading and unloading of goods 101 and / or to facilitate the entry and exit of goods 101 from the goods inlet / outlet. The wrapping mechanism 2, feeding mechanism 3, positioning mechanism 4, position detection mechanism 5, and lifting mechanism 6 are all located within the packaging compartment. The control system is electrically connected to the wrapping mechanism 2, feeding mechanism 3, positioning mechanism 4, position detection mechanism 5, and lifting mechanism 6.

[0039] Combination Figure 4 The winding mechanism 2 includes a rotating ring 21, a first driving unit 22, a material roll storage unit 23, a cutting unit 24, a material preparation unit 25, and a counterweight 26. The rotating ring 21 can rotate around its own first rotation axis, and the first driving unit 22 is used to drive the rotating ring 21 to rotate, thereby realizing the rotation of the rotating ring 21.

[0040] Preferably, the first drive unit 22 includes a first motor 221, a gear 222, and multiple limiting wheels 223. The first motor 221 and the multiple limiting wheels 223 are all mounted on the frame 1, and the gear 222 is mounted on the output shaft of the first motor 221. The rotating ring 21 is a gear ring, meaning that the outer circumference of the rotating ring 21 has teeth 211. The gear 222 meshes with the teeth 211 on the outer circumference of the rotating ring 21, so that the first motor 221 can drive the rotating ring 21 to rotate via the gear 222. Furthermore, the multiple limiting wheels 223 are distributed along the inner ring of the rotating ring 21. One of the limiting wheels 223 and one of the inner rings of the rotating ring 21 have an annular protrusion, and the other has a first annular groove. The annular protrusion and the first annular groove engage, allowing the limiting wheel 223 to support and position the rotating ring 21, and also enabling the rotating ring 21 to rotate more smoothly. The use of gear 222 to drive the rotating ring 21 ensures that the rotating ring 21 is reliably driven to rotate, avoiding jamming, slippage and other situations, and improving the reliability of the first drive unit 22 driving the rotating ring 21 to rotate.

[0041] Understandably, as an alternative, a pulley or drive belt can be used to replace the gear 222. Specifically, the pulley is mounted on the output shaft of the first motor 221, the rotating ring 21 is no longer the gear 222, and the outer circumference of the rotating ring 21 is provided with a second annular groove, with the drive belt sleeved between the pulley and the second annular groove. Alternatively, as another alternative, the structure of the rotating ring 21 can be a bearing-like structure, that is, the rotating ring 21 has an inner ring and an outer ring that can rotate relative to each other. The inner ring is fixedly mounted on the frame 1, and the outer ring is provided with the aforementioned toothed portion 211 or the second annular groove. In this embodiment, the design of multiple limiting wheels 223 and the first annular groove of the rotating ring 21 is eliminated.

[0042] Combination Figure 5 Preferably, the rotating ring 21 is provided with a first mating part 212, and the frame 1 is provided with a second position detection sensor 12. When the rotating ring 21 is in the initial position, the first mating part 212 is directly opposite the detection end of the second position detection sensor 12. The arrangement of the first mating part 212 and the second position detection sensor 12 helps to confirm the initial position of the rotating ring 21, so as to ensure that the material strip can be reliably wound on the goods 101. The second position detection sensor 12 is preferably a proximity switch.

[0043] Combination Figure 6 The material roll storage unit 23 is installed on the rotating ring 21. The material roll storage unit 23 is used to store the material roll 102 (which can be a packing film roll 102 or a tape roll, etc.), and unwind the material roll 102 to form a material strip (such as packing film or tape), and then the material strip is wrapped around the packaged goods 101 during the rotation of the rotating ring 21.

[0044] The material roll storage unit 23 includes a second connecting frame 231, a rotating frame 232, a swing frame 233, an elastic element 234, and a guide roller group 235. The second connecting frame 231 is fixedly installed on the rotating ring 21, and the rotating frame 232 is rotatably installed on the second connecting frame 231. The third rotation axis of the rotating frame 232 is basically parallel to the first rotation axis of the rotating ring 21. The rotating frame 232 is used to place the material roll 102, so as to fix the material roll 102 and enable the material roll 102 to be smoothly unwound and discharged from the conveyor belt. The first end of the swing frame 233 is rotatably connected to the second connecting frame 231, and the second end of the swing frame 233 is provided with a pressure roller 2331. It can be understood that the rotation axis of the swing frame 233 and the axis of the pressure roller 2331 are basically parallel to the first rotation axis of the rotating ring 21. The elastic element 234 is preferably a tension spring. The elastic element 234 connects the second connecting frame 231 and the swing frame 233 to force the swing frame 233 to rotate towards the third axis of the rotating frame 232. That is, under the action of the elastic element 234, the swing frame 233 can rotate towards the material roll 102 on the rotating frame 232, thereby pressing the pressure roller 2331 onto the material roll 102. This design can ensure the unwinding quality of the material strip. The guide roller group 235 is installed on the second connecting frame 231. The guide roller group 235 is used to guide the unwound material strip so that the material strip is better wound on the goods 101.

[0045] Combination Figure 7 The cutting unit 24 is used to cut the material strip after wrapping the goods 101. The cutting unit 24 includes a cutting module 241 and a first drive module 242. The first drive module 242 drives the cutting module 241 to move parallel to the first axis of rotation, so that the cutting module 241 has an extended state and a retracted state. When it is necessary to cut the material strip, the first drive module 242 drives the cutting module 241 to extend, so that the cutting module 241 cuts the material strip. When it is not necessary to cut the material strip, the first drive module 242 drives the cutting module 241 to retract, so as to prevent the material strip from getting wrapped around the goods 101 during the wrapping process, and to ensure the tightness and quality of the wrapping. Preferably, the first drive module 242 is a cylinder.

[0046] In this embodiment, the cutting module 241 includes scissors 2411, a first cylinder 2412, and a drive roller assembly 2413. The first cylinder 2412 is mounted on the drive end of the first drive module 242, and a mounting bracket is mounted on the cylinder body of the first cylinder 2412. The scissors 2411 and the drive roller assembly 2413 are mounted on the mounting bracket. The scissors 2411 has a mating part 24111. The piston rod of the first cylinder 2412 is hinged to the two blades of the scissors 2411. The mating part 24111 of the scissors 2411 is mated and connected to the drive roller assembly 2413, so that the extension and retraction of the piston rod of the first cylinder 2412 can drive the two blades of the scissors 2411 to open or close, thereby achieving the cutting of the material strip. It is understood that in some embodiments, the cutting module 241 may be pneumatic scissors, electric scissors, or other cutting modules 241 that can achieve the same function.

[0047] Combination Figure 8 The material preparation unit 25 includes a material preparation roller 251, a fourth drive module 252, a pressure rod 253, and a fifth drive module 254. The axis of the material preparation roller 251 is substantially parallel to the first rotation axis of the rotating ring 21. The material preparation roller 251 is configured to ensure that the front end of the new unwound material strip is fixed on the material preparation roller 251 after the wrapping and packaging of the goods 101 is completed and the material strip is cut, so as to ensure that the material strip can be tightly wrapped around the goods 101 when wrapping and packaging the next goods 101. When the rotating ring 21 is in the initial position, the material preparation roller 251 is located between the cutting module 241 and the material roll storage unit 23.

[0048] The fourth drive module 252 is used to drive the preparation roller 251 to move parallel to the first rotation axis of the rotating ring 21, so that before the material strip is wrapped around the product 101, after the product 101 is wrapped and packaged and the material strip is cut, the fourth drive module 252 can drive the preparation roller 251 to move to the unwound material strip to fix the end of the material strip, thereby ensuring that the material strip can be reliably wrapped onto the product 101; wherein, the fourth drive module 252 is preferably a cylinder, and the drive end of the fourth drive module 252 is preferably provided with a third connecting frame 2521 for the installation of the pressure rod 253 and the fifth drive module 254, and the preparation roller 251 is installed on the third connecting frame 2521. When the winding mechanism 2 wraps the goods 101, the fourth drive module 252 drives the preparation roller 251 to retract (i.e., exit the area where the material strip is located) to avoid the preparation roller 251 interfering with the material strip wrapping the goods 101 during the wrapping process, thus ensuring the tightness of the wrapping and the quality of the packaging.

[0049] One end of the pressure rod 253 is hinged to the third connecting frame 2521; the fifth drive module 254 includes a second cylinder 2541, a first connecting rod 2542, and a second connecting rod 2543. The cylinder body of the second cylinder 2541 is hinged to the third connecting frame 2521, and the piston rod of the second cylinder 2541 is hinged to the first end of the first connecting rod 2542 and the first end of the second connecting rod 2543, respectively. The second end of the first connecting rod 2542 is hinged to the third connecting frame 2521, and the second end of the second connecting rod 2543... The end is hinged to the pressure rod 253, allowing the second cylinder 2541 to drive the pressure rod 253 to rotate via the first connecting rod 2542 and the second connecting rod 2543. This gives the pressure rod 253 two states: open and closed. When the pressure rod 253 is in the open state, it moves away from the material preparation roller 251, and at this time, the pressure rod 253 contacts the material preparation roller 251 to clamp the material strip. When the pressure rod 253 is in the closed state, a clamping position is formed between the pressure rod 253 and the material preparation roller 251 to clamp the material strip. By setting the pressure rod 253 and the fifth drive module 254, after the material strip is cut, the fifth drive module 254 can drive the pressure rod 253 to the closed state, thereby allowing the pressure rod 253 to work with the material preparation roller 251 to clamp and fix the front end of the newly cut unwound material strip. This ensures that when wrapping and packaging the next product 101, the material strip can be tightly wrapped around the product 101.

[0050] The counterweight 26 is installed on the rotating ring 21. The counterweight 26 is used to adjust the mass distribution of the rotating ring so that the center of mass coincides with the first rotation axis, eliminate the centrifugal force imbalance when the rotating ring rotates, avoid vibration, wear and other problems, and extend the life of the winding mechanism 2 and the winding quality of the material strip.

[0051] The feeding mechanism 3 has a receiving station (such as...) Figure 1 , Figure 2 The position of the middle stage 31) and the winding station [e.g. Figure 11 The position of the middle platform 31 (located below the goods 101 and obscured by the goods 101) is such that the receiving station and the winding station are distributed along the first axis of the rotating ring, and the winding mechanism 2 is located at the winding station.

[0052] Combination Figure 9 The feeding mechanism 3 includes a platform 31, a second drive unit 32, a third drive unit 33, and a pressing unit 34. The platform 31 is used to place the goods 101 and drive the goods 101 to move between the receiving station and the winding station.

[0053] The second drive unit 32 drives the platform 31 to rotate, enabling the platform 31 to rotate the product 101 at a preset angle (e.g., 90°) at the wrapping station. This allows the wrapping mechanism 2 to continuously and uninterruptedly wrap and package the product 101 on different sides. The second drive unit 32 is preferably a second motor. The second rotation axis of the platform 31 is substantially perpendicular to the first rotation axis of the ring 21. That is, when the manufacturing and installation accuracy of the components of the wrapping machine 100 meets the requirements, the second rotation axis of the platform 31 is perpendicular to the first rotation axis of the ring 21; when the manufacturing and installation accuracy of the components of the wrapping machine 100 is insufficient, the second rotation axis of the platform 31 may intersect with the first rotation axis of the ring 21 (typically, this intersection angle should be controlled between 89° and 90°).

[0054] The third drive unit 33 is used to drive the second drive unit 32 and the platform 31 to move between the receiving station and the winding station. Preferably, the third drive unit 33 is a linear module, so that the third drive unit 33 can accurately control the moving distance of the platform 31, and thus accurately control the moving distance of the product 101, so that the material strip can be accurately wound on the designated area on the product 101. The drive end of the third drive unit 33 is provided with a mounting platform 331, and the second drive unit 32 is mounted on the mounting platform 331.

[0055] like Figure 10 As shown, preferably, a second mating part 311 is provided below the stage 31, and a third position detection sensor 332 is provided on the mounting platform 331. When the stage 31 is in the initial position, the second mating part 311 is directly opposite the detection end of the third position detection sensor 332. The arrangement of the second mating part 311 and the third position detection sensor 332 helps to more easily confirm the initial position of the stage 31, thereby facilitating the cutting unit 24 to cut the material strip. Preferably, the third position detection sensor 332 is a proximity switch.

[0056] The clamping unit 34 is mounted on the mounting platform 331, enabling it to move synchronously with the platform 31 and the second drive unit 32. The clamping unit 34 includes a clamping end 341 and a third drive module 342. The clamping end 341 is located above the platform 31, and the third drive module 342 drives the clamping end 341 to move relative to the platform 31 along its second rotation axis, thereby clamping or releasing the product 101 on the platform 31. The clamping unit 34 prevents the product 101 from shifting position during its movement from the receiving station to the winding station and during winding, while ensuring that the material strip is reliably and tightly wound around the circumference of the product 101. Preferably, the third drive module 342 is a cylinder.

[0057] Furthermore, the pressing end 341 includes a first connecting frame 3411 and a pressing member 3412. The first connecting frame 3411 is connected to the drive end of the third drive module 342. The pressing member 3412 is located between the first connecting frame 3411 and the platform 31, and the pressing member 3412 is rotatably connected to the first connecting frame 3411 around the second rotation axis of the platform 31. Through the design of the pressing end 341, when the second drive unit 32 drives the goods 101 to rotate through the platform 31, the pressing member 3412 can rotate synchronously with the platform 31 and the goods 101. On the one hand, this avoids positional displacement of the goods 101 during rotation, and on the other hand, it keeps the pressing member 3412 relatively stationary with the goods 101 or the material strip, preventing wear of the goods 101 or the material strip due to relative movement between the pressing member 3412 and the goods 101 or the material strip, thus improving the wrapping and packaging quality. Preferably, a bearing is provided between the clamping member 3412 and the first connecting frame 3411, so that the clamping member 3412 can rotate more smoothly relative to the first connecting frame 3411.

[0058] Reference Figure 3 The positioning mechanism 4 is located at the receiving station and includes two positioning units 40 distributed along a first direction, which is substantially perpendicular to the first rotation axis of the rotating ring 21. This ensures that the platform 31 is positioned between the two positioning units 40 at the receiving station. Each positioning unit 40 includes a positioning push plate 41 and a second drive module 42, which drives the positioning push plate 41 to move in the first direction. The second drive module 42 is preferably a cylinder. By positioning the product 101 at the receiving station using the two positioning units 40, the alignment of the product 101 with the first rotation axis of the rotating ring 21 is ensured, allowing the material strip to be wound more evenly and tightly around the product 101.

[0059] Furthermore, along the direction of movement from the receiving station to the winding station (i.e., the feeding direction of the product 101), a detection sensor 411 is provided at the downstream end of the positioning push plate 41. The detection sensor 411 is preferably a proximity switch. The detection sensor 411 can be used to detect whether there is a product 101 on the platform 31 and / or whether the product 101 is positioned at a set position.

[0060] The position detection mechanism 5 includes a first position detection sensor 51 and a fourth drive unit 52. In this embodiment, the first position detection sensor 51, in its initial position, is located downstream of the rotating ring 21 in the feeding direction. The fourth drive unit 52 is mounted on the winding mechanism 2 and is used to drive the first position detection sensor 51 to move parallel to the first rotation axis of the rotating ring 21. That is, when the platform 31 moves towards the winding station, the fourth drive unit 52 drives the first position detection sensor 51 to extend towards the platform 31 in the opposite direction of the feeding direction to a set position. When the first position detection sensor 51 detects that the product 101 on the platform 31 has moved to the winding station and reached the designated position, the control system of the winding machine 100 controls the third drive unit 33 to stop driving the platform 31, so that the platform 31 remains in the designated position. The fourth drive unit 52 is preferably a cylinder; the first position detection sensor 51 can be a proximity switch, an infrared sensor, a distance sensor, etc.

[0061] As another alternative, the first position detection sensor 51 can also be located at the winding station, and the first position detection sensor 51 is kept at a preset distance from the rotating ring 21 in the feeding direction. In this case, the fourth drive unit 52 can drive the first position detection sensor 51 to move relative to the platform 31 at the winding station in the radial direction of the rotating ring 21. This setting can also enable the first position detection sensor 51 to detect the position of the goods 101 on the platform 31, so that the platform 31 and the goods 101 reach the designated position.

[0062] As can be seen, the first position detection sensor 51 detects the position of the goods 101 on the platform 31 as it moves from the receiving station to the winding station, so that the third drive unit 33 can adjust the relative position of the goods 101 and the winding mechanism 2 to ensure that the material strip is reliably wound on the goods 101 according to the set position; while the fourth drive unit 52 can adjust the position of the first position detection sensor 51 so that the first position detection sensor 51 is retracted during the winding and packaging process of the winding mechanism 2 on the goods 101, so as to avoid interference between the first position detection sensor 51 and the material strip.

[0063] The lifting mechanism 6 is located at the receiving station and between the platform 31 and the pad 11. The lifting mechanism 6 includes a top plate 61 and a fifth drive unit 62. The fifth drive unit 62 is used to drive the top plate 61 to move parallel to the second rotation axis of the platform 31. The top plate 61 is provided with a clearance position 611 to avoid interference and collision between the platform 31 and the top plate 61 when the platform 31 needs to be rotated at the receiving station. Preferably, the fifth drive unit 62 is a cylinder.

[0064] The following combination Figure 3 and Figure 11A brief description of the working process of the winding machine 100: When it is necessary to package the goods 101, the goods 101 is placed on the platform 31; then the two positioning units 40 of the positioning mechanism 4 adjust the position of the goods 101 through the positioning push plate 41, so that the center line of the goods 101 is aligned with the first rotation axis of the rotating ring 21, ensuring the alignment of the goods 101 with the first rotation axis of the rotating ring 21.

[0065] Next, the third drive module 342 of the clamping unit 34 controls the clamping end 341 to clamp onto the goods 101; subsequently, the positioning mechanism 4 resets.

[0066] Next, the fourth drive unit 52 of the position detection mechanism 5 drives the first position detection sensor 51 to extend in preparation for detecting the position of the goods 101. It should be noted that this step can be performed simultaneously with the clamping unit 34 performing the clamping operation; it can also be performed simultaneously with the third drive unit 33 performing the drive operation to move the platform 31 towards the winding station; or it can be performed before the clamping unit 34 performs the clamping operation.

[0067] Next, the third drive unit 33 drives the platform 31, the second drive unit 32 and the clamping unit 34 to move toward the winding station; when the first position detection sensor 51 detects that the product 101 has moved to the designated position, the third drive unit 33 stops driving the platform 31, the second drive unit 32 and the clamping unit 34 to move; subsequently, the fourth drive unit 52 of the position detection mechanism 5 drives the first position detection sensor 51 to retract.

[0068] Next, the first drive unit 22 of the winding mechanism 2 drives the rotating ring 21 to rotate, so that the material roll 102 on the material roll storage unit 23 is unwound and the material roll is wound around the goods 101.

[0069] When the first drive unit 22 drives the rotating ring 21 to rotate at a first preset angle, the fifth drive module 254 of the material preparation unit 25 drives the pressure rod 253 to open, so that the pressure rod 253 and the material preparation roller 251 release the clamping of the material strip; then, the fourth drive module 252 drives the material preparation roller 251, the pressure rod 253 and the fifth drive module 254 to retract.

[0070] Next, the first drive unit 22 of the winding mechanism 2 continues to drive the rotating ring 21 to rotate at a second preset angle, so that the material strip continues to be wound on the product 101. It should be noted that the rotation speed of the first drive unit 22, the fourth drive module 252, the fifth drive module 254, etc., can be adjusted so that the rotating ring 21 keeps rotating continuously during the above process. It can be understood that even if the rotating ring 21 pauses briefly during the winding and packaging process of the winding mechanism 2 on the product 101 before the material strip is cut, it should be understood as continuous and uninterrupted winding and packaging of the product 101. When the first drive unit 22 drives the rotating ring 21 to complete the rotation at the second preset angle, the winding and packaging of the first side circumference of the product 101 is completed.

[0071] Next, the first drive unit 22 of the winding mechanism 2 preferably drives the rotating ring 21 to pause briefly, while the second drive unit 32 drives the platform 31 to rotate at a preset angle (such as 90°), and the third drive unit 33 drives the platform 31, the second drive unit 32 and the pressing unit 34 to move relative to the rotating ring 21 in the feeding direction to ensure that the material strip is wound in the set area of ​​the goods 101; at this time, the goods 101 are prepared to be wrapped and packaged on the second side circumference. It is understandable that, due to the possible existence of long and short sides of the goods 101, especially for goods 101 that are cuboid boxes, cuboid block structures, or cuboid block combination structures, the relative distance between the end face of the goods 101 and the rotating ring 21 changes after the goods 101 rotates at a preset angle with the platform 31. If the material tape is directly wound around the goods 101 at this time, the winding position of the material tape on the second side circumference of the goods 101 will be a non-set area. Therefore, it is necessary to adjust the position of the platform 31 and the goods 101 on it according to the rotation direction of the goods 101 by the third drive unit 33.

[0072] After the goods 101 have rotated to a preset angle following the platform 31, the first drive unit 22 of the winding mechanism 2 continues to drive the rotating ring 21 to rotate to a third preset angle. When the rotating ring 21 completes the rotation to the third preset angle, the second side circumference of the goods 101 is wrapped and packaged. Then, following the same processing method as described above, the platform 31 and the goods 101 on it are rotated again, and the relative distance between the rotated platform 31, the goods 101 and the rotating ring 21 is adjusted, finally completing the wrapping and packaging of all side circumferences of the goods 101.

[0073] During the wrapping process on the last side of the product 101, the first drive unit 22 of the wrapping mechanism 2 first drives the rotating ring 21 to rotate at a fourth preset angle. When the rotating ring 21 rotates to the fourth preset angle, the fourth drive module 252 of the material preparation unit 25 drives the material preparation roller 251, the pressure rod 253 and the fifth drive module 254 to extend. Then, the first drive unit 22 of the wrapping mechanism 2 continues to drive the rotating ring 21 to rotate at a fifth preset angle. During this process, a portion of the material strip is wrapped around the material preparation roller 251. Subsequently, the fifth drive module 254 drives the pressure rod 253 to close, so that the pressure rod 253 cooperates with the material preparation roller 251 to clamp the material strip.

[0074] When the rotating ring 21 completes the fifth preset angle rotation, the first drive module 242 of the cutting unit 24 drives the cutting module 241 to cut the material strip. After that, the first drive module 242 drives the cutting module 241 to retract and return to its original position, while the material preparation unit 25 remains in the current rotation.

[0075] Next, the third drive unit 33 drives the platform 31 and the goods 101 on it, the second drive unit 32, the clamping unit 34, etc. to reset (i.e. move to the receiving position); then, the clamping unit 34 releases the clamp on the goods 101. At this point, the continuous and uninterrupted wrapping and packaging process of the goods 101 on different circumferential surfaces is completed.

[0076] In summary, the design of the feeding mechanism 3 allows it to transfer the packaged goods 101 to the wrapping station. First, the wrapping mechanism 2 wraps the first circumferential surface of the goods 101 with a material strip (such as packing film or tape). Then, through the cooperation of the second drive unit 32 and the third drive unit 33, the goods 101 rotates at a preset angle at the wrapping station. This allows the wrapping mechanism 2 to directly wrap the second, third, and fourth circumferential surfaces of the goods 101. Simultaneously, it allows for the adjustment of the goods 101 during rotation. During the wrapping process, there is no need to cut the material strip (of course, depending on the packaging requirements, the wrapping machine 100 of this application may also cut the material strip when the goods 101 are packaged on different sides. During this process, the goods 101 only needs to rotate in place at the wrapping station to adjust its position through the platform 31, the second drive unit 32 and the third drive unit 33). This enables the wrapping mechanism 2 to continuously and uninterruptedly wrap the material strip on each side of the goods 101, ensuring the continuity and reliability of the packaging, and also improving the wrapping efficiency of the wrapping machine 100. When rotating to adjust the position of the goods 101, the third drive unit 33 can control the platform 31 to move, thereby precisely adjusting the relative position of the goods 101 and the conveyor belt according to the size of the goods 101. For example, when wrapping the short side of the goods 101, the third drive unit 33 drives the platform 31 closer to the wrapping mechanism 2; when wrapping the long side of the goods 101, the third drive unit 33 drives the platform 31 away from the wrapping mechanism 2. It should be noted that the above "closer" and "away" refer to the relative distance between the platform 31 and the wrapping mechanism 2 when wrapping the short side and long side of the goods 101.

[0077] Production line example The production line includes the winding machine described in the above-mentioned winding machine embodiment, wherein the goods can be placed onto the loading platform manually; of course, in order to improve the automation level of the production line, the production line may also include a feeding device to automatically feed the goods onto the loading platform, or the production line may also include a feeding robot to automatically load and unload the goods onto the loading platform.

[0078] By installing the aforementioned wrapping machine, the production line can continuously wrap and package multiple circumferences of goods, thereby increasing the degree of automation and improving production efficiency.

For those skilled in the art, the present utility model can have various changes and modifications.
