Description

Technical Field

[0001] This invention belongs to the technical field of packaging machinery and equipment, specifically relating to an automatic winding and splicing device. This invention also relates to a method for automatic winding and splicing using the above-mentioned automatic winding and splicing device. Background Technology

[0002] In the printing process, to simultaneously achieve the automatic splicing requirements of both "inner roll" and "outer roll" in the winding process, two sets of automatic splicing devices are generally needed for winding, one for "inner roll" upper cutting and the other for "outer roll" lower cutting. Currently used linear guide automatic winding splicing devices use one set of linear guide splicing components to achieve gap winding, with two sets of cutting components used for upper and lower cutting respectively. The advantage is that one device can control the corresponding cutting components according to different winding processes, without interference between them, resulting in gap winding on the linear guide and a flat material roll. The disadvantage is that during splicing and cutting, and gap winding on the linear guide, the wrap angle of the material shaft varies with the roll diameter, leading to a large deviation between the smallest and largest rolls, and making the core wrinkle more likely during winding. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic winding and splicing device that solves the problem that in existing devices, the winding wrap angle of the material shaft varies with the roll diameter during splicing and cutting and winding with the gap between the linear guide rails, resulting in a large deviation between the smallest and largest rolls and making the core wrinkles easy to occur during winding.

[0004] A second objective of this invention is to provide a method for automatically splicing rewinding components using the aforementioned automatic rewinding and splicing device.

[0005] The first technical solution adopted in this invention is an automatic winding and splicing device, including a main equipment support frame, a winding turret rotatably mounted on the main equipment support frame, and a swing arm cylinder fixedly mounted on the main equipment support frame. The winding turret is located on one side of the swing arm cylinder, and a splicing and cutting component is connected to the working end of the swing arm cylinder. The splicing and cutting component is rotatably mounted on the main equipment support frame via a rotating shaft. An encoder is connected to one side of the splicing and cutting component, and the encoder is connected to an industrial control PLC via a wired connection.

[0006] The invention is further characterized by:

[0007] The splicing and cutting assembly includes a swing arm frame, which is rotatably mounted on the main support of the equipment via a rotating shaft. The working end of the swing arm cylinder is connected to the middle part of one side of the swing arm frame. One end of the swing arm frame is provided with a counterweight block. A rubber roller is also rotatably mounted on the end of the swing arm frame away from the counterweight block. A guide roller device is also movably connected to the swing arm frame. A cutter seat is provided on the end of the swing arm frame away from the counterweight block, and the cutter seat is located outside the rubber roller.

[0008] The splicing and cutting assembly also includes a cutting cylinder, which is fixed on the swing arm and located between the rotating shaft and the rubber roller. The working end of the cutting cylinder is connected to the cutting base.

[0009] The cutter holder contains a lower cutting blade and an upper cutting blade.

[0010] The connection between the swing arm frame and the swing arm cylinder is located between the rotating shaft and the guide roller device.

[0011] The winding turret includes a winding roll, a guide roll assembly, and a rubber roller, all of which are arranged parallel to the winding roll.

[0012] The second technical solution adopted in this invention is an automatic winding and splicing method, which uses the above-mentioned automatic winding and splicing device, and the specific steps are as follows:

[0013] S1. Switch the cutting mode according to the winding process, confirm the initial position of the splicing cutting component and the cutter holder, and at the same time determine the material path of the guide roller device.

[0014] S2. The new material shaft is wound with tape, and the winding turret rotates the new material shaft to the required operating position;

[0015] S3. Automatic winding and splicing process controlled by industrial PLC;

[0016] S4. Based on the actual situation, the approach roller gap winding process is controlled by the industrial control PLC to complete the entire automatic winding and splicing process.

[0017] The invention is further characterized by:

[0018] The winding process in S1 includes "surface winding" or "inner winding", and the cutting modes include top cutting mode and bottom cutting mode.

[0019] The specific operation method for S1 is as follows:

[0020] The encoder reads the specific position and rotation direction signals of the splicing and cutting components and transmits them to the industrial control PLC. The industrial control PLC controls the swing arm cylinder to complete the corresponding upper cutting mode / lower cutting mode switching of the splicing and cutting components based on the position signal feedback. When the cylinder rod of the swing arm cylinder is fully retracted, it is the initial position of the upper cutting mode. When the cylinder rod of the swing arm cylinder is fully extended, it is the initial position of the lower cutting mode.

[0021] The industrial control PLC confirms the working mode of the splicing and cutting component based on the position signal feedback read by the encoder, and then controls the cutting cylinder to switch the position of the cutting blade. When the cylinder rod extends, it is the upper cutting mode, and the lower cutting blade extends at this time. When the cylinder rod retracts, it is the lower cutting mode, and the upper cutting blade extends at this time.

[0022] Manually change the installation position of the guide roller device to switch the material feeding route; top feeding is the top cutting mode, and bottom feeding is the bottom cutting mode.

[0023] The specific operation method for S3 is as follows:

[0024] S3.1 Keep the winding unit on the winding turret in operation;

[0025] S3.2 The swing arm cylinder controls the splicing and cutting assembly to rotate from the initial position to the working position and then stop, while the material shaft accelerates synchronously;

[0026] S3.3, the swing arm cylinder performs an action that causes the rubber roller to start pressing the material, and the cutter cylinder controls the cutter seat, so that the upper or lower cutter blade works to cut the material roll, and then the upper or lower cutter blade resets.

[0027] S3.4 The winding turret rotates to a position close to the initial winding position of the roller gap, and at the same time, the splicing and cutting assembly is rotated to a position close to the initial winding position of the roller gap by the operation of the swing arm cylinder.

[0028] The specific operation method of S4 is as follows:

[0029] S4.1 The industrial control PLC controls the swing arm cylinder to perform actions based on the roll diameter data of the winding turret and the position signal of the splicing and cutting component, driving the splicing and cutting component to rotate intermittently, keeping it in a "stop-rotate-stop" state, and always keeping the material shaft winding wrap angle stable within a range, achieving near-roll gap winding.

[0030] S4.2 When the winding turret's diameter reaches the set value, the swing arm cylinder performs an action, and the splicing and cutting component rotates to the initial position.

[0031] The beneficial effects of this invention are:

[0032] The automatic winding and splicing device of the present invention uses a swing arm structure to achieve near-roller gap winding, and always keeps the winding wrap angle of the material shaft within a stable range. This solves the problem that in the existing device, when splicing and cutting and winding between the linear guide rail gap, the winding wrap angle of the material shaft varies with the roll diameter, the deviation between the smallest and largest rolls is large, and the winding core wrinkles are easy to occur.

Detailed Implementation

[0047] The present invention will now be described in detail with reference to specific embodiments.

[0048] Automatic winding and splicing device, such as Figure 1As shown, the equipment includes a main support frame, on which a winding turret 4 is rotatably mounted. The center of the winding turret 4 is mounted on the main support frame via a rotating shaft. A swing arm cylinder 3 is also fixed on the main support frame. The air circuit of the swing arm cylinder 3 uses cylinder body pressure holding for positioning. The winding turret 4 is located on one side of the swing arm cylinder 3. The working end of the swing arm cylinder 3 is connected to a splicing and cutting component 1. The splicing and cutting component 1 is also rotatably mounted on the main support frame via a rotating shaft. An encoder 2 is connected to one side of the splicing and cutting component 1. The encoder reads the rotation position signal of the splicing and cutting component 1. The encoder 2 is connected to an industrial control PLC via a wired connection. The industrial control PLC then controls the cylinder. Specifically, based on the position signal read by the encoder 2, the industrial control PLC controls the swing arm cylinder 3 to extend, retract, or stop at any position and then maintain cylinder body pressure, that is, the splicing and cutting component 1 rises, falls, or stops at any position.

[0049] Specifically, such as Figure 2 As shown, the splicing and cutting assembly 1 includes a swing arm 1-1, which is rotatably mounted on the main support of the equipment via a rotating shaft. The rotating shaft is specifically located in the middle of the swing arm 1-1, not at either end, ensuring that the swing arm 1-1 can rotate around the rotating shaft under the push of the swing arm cylinder 3 during operation. The working end of the swing arm cylinder 3 is connected to the middle part of one side of the swing arm 1-1, specifically as shown... Figure 1 As shown, a counterweight 1-2 is provided at one end of the swing arm 1-1, and a rubber roller 1-4 is rotatably provided at the end of the swing arm 1-1 away from the counterweight 1-2. A guide roller device 1-3 is also movably connected to the swing arm 1-1. The position of the guide roller device 1-3 can be manually adjusted according to the situation during actual operation, and the installation position of the guide roller device 1-3 can be manually changed to switch the material feeding route (upper cutting mode or lower cutting mode). This structure is existing technology and will not be described in detail. A cutter seat 1-5 is provided at the end of the swing arm 1-1 away from the counterweight 1-2. The cutter seat 1-5 is close to the rubber roller 1-4 and located outside the rubber roller 1-4. A lower cutting blade 1-6 and an upper cutting blade 1-7 are movably arranged in the cutter seat 1-5, which are used for lower cutting and upper cutting, respectively.

[0050] The splicing and cutting assembly 1 also includes a cutting cylinder 1-8, which is fixed on the swing arm frame 1-1. The cutting cylinder 1-8 is located between the rotating shaft and the rubber roller 1-4. The working end of the cutting cylinder 1-8 is connected to the cutting base 1-5. The cutting cylinder 1-8 can push the cutting base 1-5 to rotate on the swing arm frame 1-1 according to the required cutting position, so as to complete the upper cutting or lower cutting according to different states. The initial state of the cutting cylinder 1-8 is the upper cutting mode when the cylinder rod is extended, and the initial state is the lower cutting mode when it is retracted.

[0051] The connection between the swing arm frame 1-1 and the swing arm cylinder 3 is located between the rotating shaft and the guide roller device 1-3, which facilitates actual operation.

[0052] The winding turret 4 includes a winding roller, guide roller devices 1-3, and rubber rollers 1-4, all of which are arranged parallel to the winding roller. This design ensures that the material roll can be transferred and operated normally.

[0053] The automatic winding and splicing method, using the aforementioned automatic winding and splicing device, involves the following specific steps:

[0054] S1. Switch the cutting mode according to the winding process, where the winding process includes "surface winding" or "inner winding", and the cutting mode includes upper cutting mode and lower cutting mode, thereby confirming the initial position of the splicing cutting component 1 and the cutter holder 1-5, and at the same time determining the material feeding path of the guide roller device 1-3. The specific method is as follows:

[0055] The encoder 2 reads the specific position and rotation direction signal of the splicing and cutting component 1 and transmits it to the industrial control PLC. The industrial control PLC controls the swing arm cylinder 3 to complete the corresponding upper cutting mode / lower cutting mode switching of the splicing and cutting component 1 based on the position signal feedback. When the cylinder rod of the swing arm cylinder 3 is fully retracted, it is the initial position of the upper cutting mode. When the cylinder rod of the swing arm cylinder 3 is fully extended, it is the initial position of the lower cutting mode.

[0056] The industrial control PLC confirms the working mode of the splicing and cutting component 1 based on the position signal feedback from the encoder 2, and then controls the cutting cylinders 1-8 to switch the cutting blade position. When the cylinder rod extends, it is in the upper cutting mode, and the lower cutting blades 1-6 extend at this time. When the cylinder rod retracts, it is in the lower cutting mode, and the upper cutting blades 1-7 extend at this time.

[0057] Manually change the installation position of guide roller devices 1-3 to switch the material feeding route. Upward feeding is the upper cutting mode, and downward feeding is the lower cutting mode.

[0058] S2. The new material shaft is wound with tape, and the winding turret 4 rotates the new material shaft to the desired operating position.

[0059] S3. The automatic winding and splicing process is controlled by an industrial PLC. The specific operation method is as follows:

[0060] S3.1 Keep the winding unit on the winding turret 4 in operation;

[0061] S3.2, The swing arm cylinder 3 controls the splicing and cutting component 1 to rotate from the initial position to the working position and then stop, and the material shaft accelerates synchronously;

[0062] S3.3, the swing arm cylinder 3 performs the action to make the rubber roller 1-4 start pressing the material, and the cutter cylinder 1-8 controls the cutter seat 1-5, so that the upper cutter 1-7 or the lower cutter 1-6 works to cut the material roll, and then the upper cutter 1-7 or the lower cutter 1-6 resets.

[0063] S3.4 The winding turret 4 rotates to a position close to the initial winding position of the roller gap, and at the same time, the swing arm cylinder 3 drives the splicing and cutting assembly 1 to rotate to a position close to the initial winding position of the roller gap.

[0064] S4. Based on the actual situation, the approach roller gap winding process is controlled by the industrial control PLC to complete the entire automatic winding and splicing process. The specific operation method is as follows:

[0065] S4.1 The industrial control PLC controls the swing arm cylinder 3 to perform actions based on the roll diameter data of the winding turret 4 and the position signal of the splicing and cutting component 1, so as to drive the splicing and cutting component 1 to rotate intermittently and keep it in the state of "stop-rotate-stop", so as to keep the material shaft winding wrap angle stable within a range and achieve near-roll gap winding.

[0066] S4.2 When the winding diameter of the winding turret 4 reaches the set value, the swing arm cylinder 3 performs an action, and the splicing and cutting component 1 rotates to the initial position.
