Description

Technical Field

[0001] The utility model relates to the technical field of roll changing, in particular to an automatic roll changing machine. Background Art

[0002] After large flexible sheet products such as paper and cloth are produced, they need to be wound up by winding, so that they can be conveniently stored and transported. After each roll of material is wound up, its width and thickness are quite high, making each roll of material quite heavy. If only relying on personnel to recycle the material and then replace the winding core by personnel, it will cause extremely low efficiency and pose a safety hazard to the staff.

[0003] In the related art, a push rod is arranged at the end of the core away from the outlet of the rolled material. When the winding is completed, the rolled material is pushed into the slope by the push rod. A trolley is placed under the slope for receiving. A core changing groove is arranged above the distal end of the push rod for receiving a new core and recycling it through the push rod. However, in this structure, the heavy rolled material will directly rush into the trolley with the help of the slope, which has a safety hazard. And after the rolled material is recycled, the new core needs to be manually placed into the core changing groove, resulting in low work efficiency. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an automatic roll changing machine, aiming to improve the working efficiency of the roll changing machine and improve its working stability.

[0005] To achieve the above purpose, an automatic roll changing machine proposed by the utility model includes a roll outlet mechanism and a transfer component:

[0006] The roll outlet mechanism includes a driving component, a telescopic rod and a power gripper. The telescopic rod is drivingly connected to the driving component. One end of the telescopic rod away from the driving component is rotatably connected to the power gripper. A buffer structure is arranged on the gripper head of the power gripper; and

[0007] The transfer component is arranged facing the power gripper and is below the power gripper. The transfer component is provided with a storage groove facing the power gripper. Installation parts are arranged at both ends of the transfer component away from the storage groove. The bottom edge of the installation part is rotatably connected to an upper roll arm near the end of the roll outlet mechanism. A clamping groove is arranged at one end of the upper roll arm away from the installation part.

[0008] In an embodiment of the present application, there are two groups of the driving components, and the two groups of the driving components are arranged side by side, one above the other. The telescopic rod includes a stable rod and an adjusting rod. The stable rod is connected to the driving component above. The adjusting rod is connected to the driving component below. The telescopic range of the adjusting rod is greater than that of the stable rod.

[0009] In an embodiment of the present application, a stabilizing bracket is further included. The stabilizing bracket is located below the unwinding mechanism and is arranged facing the transfer assembly. The stabilizing bracket is provided with lifting jaws facing the storage slot. One end of the stabilizing bracket away from the lifting jaws is rotatably connected to a bracket. A core is arranged between the bracket and the lifting jaws.

[0010] In an embodiment of the present application, a lifting mechanism is provided on the stabilizing bracket relative to the bracket. One end of the bracket away from the core is rotatably connected to the lifting mechanism, which is used to enable the bracket and the lifting jaws to grip the core and perform reciprocating motion along the movement trajectory of the lifting jaws.

[0011] In an embodiment of the present application, a blanking plate is provided at one end of the transfer assembly facing the unwinding mechanism. The blanking plate is connected to the storage slot. One end of the blanking plate facing the bottom edge of the storage slot is rotatably connected to the side edge of the transfer assembly.

[0012] In an embodiment of the present application, clamping plates are rotatably connected to the side of the bottom edge of the storage slot. There are two groups of clamping plates, and the two clamping plates are arranged oppositely. The bottom edge of the blanking plate is connected to the periphery of one of the clamping plates.

[0013] In an embodiment of the present application, a coiling mechanism is further included. The coiling mechanism is provided with a discharge port. The unwinding mechanism and the stabilizing bracket are connected to the discharge port. The transfer assembly is connected to the periphery of the coiling mechanism. The lifting jaws are drivingly connected to the side wall of the discharge port and are arranged facing the transfer assembly.

[0014] The technical solution of the present utility model splits the automatic roll changer into a roll discharging mechanism and a transfer component in terms of structure and function. The roll discharging mechanism is used to transfer the wound material roll away from the coiling mechanism. In order to improve safety performance and be able to transfer the material roll quickly and stably, the roll discharging mechanism includes a driving component, a telescopic rod, and a power gripper. The driving component is arranged along the direction of the material roll discharging, and the driving component is drivingly connected to the telescopic rod, and the two together form a telescopic structure. A power gripper is rotatably connected to the end of the telescopic rod far from the driving component. The power gripper directly clamps the two ends of the material roll by rotating inwards. The material roll can be moved outwards through the telescopic structure. A buffer structure is provided at the gripper head of the power gripper, which can include structures such as springs and cylinders. In this way, additional power assistance can be provided to take out the material roll. At the same time, when the material roll approaches the transfer component, the power gripper rotates at the slope and more stably pulls out the material roll with the help of the buffer structure. The buffer structure can extend the gripper head part of the gripper, which can avoid damage to the gripper head and improve the safety of the equipment. The transfer component is provided with a storage groove facing the power gripper, which can be used to fix the placed material roll to prevent it from moving. After transfer, the material roll can be smoothly transferred by borrowing other blanking structures. At the same time, installation parts are provided at both ends of the storage groove, and the installation parts are higher than the bottom end of the storage groove, which can play a role in limiting the two ends of the material roll and protecting the material roll to the greatest extent. An upper coiling arm is provided in the installation part, which is connected to the bottom end of the installation part and is arranged close to the coiling mechanism. After blanking, the core can be re-inserted into the coiling mechanism through the upper coiling arm, making the whole structure more flexible. A clamping groove is provided on the upper coiling arm for more stably grasping the core and feeding it into the machine. Through the above structure, the roll changing operation can be completed quickly and stably, improving the efficiency and ensuring its safety at the same time. Brief Description of the Drawings

[0022] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] Referring to Figures 1 to 3 , in an embodiment of the present utility model, an automatic roll changer is proposed, which includes an uncoiling mechanism 2 and a transfer component 3. The uncoiling mechanism 2 includes a driving component 21, a telescopic rod 22 and a power gripper 23. The telescopic rod 22 is drivingly connected to the driving component 21. One end of the telescopic rod 22 away from the driving component 21 is rotatably connected to the power gripper 23. A buffer structure 24 is provided on the chuck of the power gripper 23. The transfer component 3 is arranged facing the power gripper 23 and is located below the power gripper 23. The transfer component 3 is provided with a storage groove 31 facing the power gripper 23. At both ends of the transfer component 3 away from the storage groove 31, there are mounting parts 32. The bottom edge of the mounting part 32 is rotatably connected to an upper coiling arm 33 near the end of the uncoiling mechanism 2. A clamping groove is provided at one end of the upper coiling arm 33 away from the mounting part 32.

[0024] In an automatic roll changer of the present application, the automatic roll changer is structurally and functionally split into a roll discharging mechanism 2 and a transfer assembly 3. The roll discharging mechanism 2 is used to transfer the wound roll away from the roll stock mechanism 1. To improve safety performance and enable rapid and stable transfer of the roll, the roll discharging mechanism 2 includes a driving assembly 21, a telescopic rod 22, and a power gripper 23. The driving assembly 21 is arranged along the direction of roll discharging, and the driving assembly 21 is drivingly connected to the telescopic rod 22, and the two together form a telescopic structure. A power gripper 23 is rotatably connected to the end of the telescopic rod 22 away from the driving assembly 21. The power gripper 23 directly clamps the two ends of the roll by rotating inwards. The roll can be moved outwards through the telescopic structure. A buffer structure 24 is provided at the gripper head of the power gripper 23, which can include structures such as springs and cylinders. In this way, additional power assistance can be provided to remove the roll. At the same time, when the roll approaches the transfer assembly 3, the power gripper 23 rotates at the slope and more stably pulls out the roll with the help of the buffer structure 24. The buffer structure 24 can extend the gripper head part of the gripper, avoid damage to the gripper head, and improve the safety of the equipment. The transfer assembly 3 is provided with a storage groove 31 facing the power gripper 23, which can be used to fix the placed roll and prevent it from moving. After transfer, the roll can be smoothly transferred by borrowing other blanking structures. At the same time, mounting parts 32 are provided at both ends of the storage groove 31. The mounting parts 32 are higher than the bottom end of the storage groove 31, which can play a role in limiting the two ends of the roll and protect the roll to the greatest extent. An upper roll arm 33 is provided in the mounting part 32. It is connected to the bottom end of the mounting part 32 and is arranged close to the roll stock mechanism 1. After blanking, the core 5 can be re-inserted into the roll stock mechanism 1 through the upper roll arm 33, making the whole structure more flexible. A clamping groove is provided on the upper roll arm 33 for more stably grasping the core 5 and feeding it into the machine. Through the above structure, the roll changing operation can be completed quickly and stably, improving efficiency while ensuring its safety.

[0025] With reference to Figures 1 to 2 , in an embodiment of the present application, two sets of driving assemblies 21 are provided. The two sets of driving assemblies 21 are arranged side by side, one above the other. The telescopic rod 22 includes a stabilizing rod 221 and an adjusting rod 222. The stabilizing rod 221 is connected to the driving assembly 21 at the upper part, and the adjusting rod 222 is connected to the driving assembly 21 at the lower part. The telescopic range of the adjusting rod 222 is greater than that of the stabilizing rod 221.

[0026] In an automatic roll-changing machine of the present application, there are two sets of driving components 21. The two sets of driving components 21 are arranged side by side, one above the other. The telescopic rod 22 includes a stabilizing rod 221 and an adjusting rod 222. In such a structure, when the two telescopic rods 22 are simultaneously rotatably connected to the power gripper 23, as long as the maximum telescopic lengths of the two telescopic rods 22 are the same, the power gripper 23 can be perpendicular to the bottom of the storage groove 31 to achieve the purpose of restricting braking, making the operation of the machine more stable. In order to enable the power gripper 23 to extend into the coil mechanism 1 to collect the coil, the telescopic range of the adjusting rod 222 is greater than that of the stabilizing rod 221, making the movement of the power gripper 23 more stable and achieving the purpose of protecting the equipment.

[0027] Referring to Figures 1 to 2 , in an embodiment of the present application, it further includes a stabilizing bracket 4. The stabilizing bracket 4 is located below the coil discharging mechanism 2 and faces the transfer component 3. The stabilizing bracket 4 is provided with a lifting gripper 41 facing the storage groove 31. One end of the stabilizing bracket 4 away from the lifting gripper 41 is rotatably connected to a bracket 42, and a core 5 is provided between the bracket 42 and the lifting gripper 41.

[0028] In an automatic roll-changing machine of the present application, a stabilizing bracket 4 is further provided between the coil discharging mechanism 2 and the transfer component 3. With the help of the stabilizing bracket 4, the core 5 of the coil can always not leave the machine. What needs to be replaced is the coil core. The material is wound around the coil core. When discharging, the lifting gripper 41 can first clamp one end of the core 5. Under the restriction of the installation part 32, the transfer component 3 can carry the material and the coil core and move in a direction away from the lifting gripper 41. At this time, the core 5 and the coil core are slidably connected. When the two are separated by a certain distance, the bracket 42 rotates and catches the core 5, and the coil can be stably separated from the core 5.

[0029] Referring to Figure 2 , in an embodiment of the present application, a lifting mechanism 43 is provided on the stabilizing bracket 4 relative to the bracket 42. One end of the bracket 42 away from the core 5 is rotatably connected to the lifting mechanism 43, which is used to enable the bracket 42 and the lifting gripper 41 to grab the core 5 and make a reciprocating motion along the movement track of the lifting gripper 41.

[0030] In an automatic roll-changing machine of the present application, a lifting mechanism 43 is provided on the stabilizing bracket 4 relative to the bracket 42. Because after the transfer component 3 sends away the coil, a new coil core can be put in. The coil core itself can be made of paper for convenient transportation and is relatively light, so it can be easily sent into the transfer component 3. When sending back the coil core, because there is no material, its height is relatively low. In order to enable the coil core to be successfully sleeved on the core 5, the height can be adjusted through the lifting mechanism 43 and the lifting gripper 41, and it can be easily sleeved into the core 5. With the help of the upper winding arm 33, the upper winding operation can be stably completed.

[0031] Referring to Figure 3 , in an embodiment of the present application, a blanking plate 34 is provided at one end of the transfer assembly 3 facing the unwinding mechanism 2. The blanking plate 34 is connected to the storage tank 31, and one end of the blanking plate 34 facing the bottom edge of the storage tank 31 is rotatably connected to the side edge of the transfer assembly 3.

[0032] In an automatic roll changer of the present application, a blanking plate 34 is provided at one end of the transfer assembly 3 facing the unwinding mechanism 2. Through the blanking plate 34, when the transfer assembly 3 reaches a specified position, the blanking plate 34 can be automatically opened. The blanking plate 34 rotates to form a slope, enabling rapid blanking and significantly improving the working efficiency of the machine.

[0033] Referring to Figure 3 , in an embodiment of the present application, a clamping plate 35 is rotatably connected to the side of the bottom edge of the storage tank 31. There are two sets of clamping plates 35, and the two clamping plates 35 are arranged oppositely. The bottom edge of the blanking plate 34 is connected to the periphery of one clamping plate 35.

[0034] In an automatic roll changer of the present application, a clamping plate 35 is rotatably connected to the side of the bottom edge of the storage tank 31. When the blank roll core enters the storage tank 31, one side clamping plate 35 can be raised first, enabling the roll core to quickly reach the specified position. The two clamping plates 35 are raised simultaneously to clamp the lighter roll core, avoiding the failure of loading due to the displacement of the roll core when aligning the roll core and the roll core 5, and improving the stability of the entire structure.

[0035] Referring to Figures 1 to 2 , in an embodiment of the present application, it further includes a coiling mechanism 1. The coiling mechanism 1 is provided with a discharge port. The unwinding mechanism 2 and the stable support 4 are connected to the discharge port. The transfer assembly 3 is connected to the periphery of the coiling mechanism 1. The lifting gripper 41 is drivingly connected to the side wall of the discharge port and is arranged facing the transfer assembly 3.

[0036] In an automatic roll changer of the present application, the entire roll changer is installed on the coiling mechanism 1, and the above structures are all arranged at the discharge port of the coiling mechanism 1. Among them, the unwinding mechanism 2 and the stable support 4 are connected to the discharge port, and the transfer assembly 3 can reciprocate around the discharge port. Through the above structures, a fully automatic roll loading and unloading process can be quickly and stably achieved, and the entire process is made faster and more stable, improving the user experience.
