Description

Technical Field

[0001] The invention belongs to the field of film processing equipment, and in particular relates to an auxiliary roll loading and unloading device of a slitting machine, a slitting machine and a use method thereof. Background Art

[0002] At present, there are many types of slitting machines, and their prices range widely due to different sizes, materials and automation levels. In the process of unloading the slitting machine, most of them are currently achieved through manual operation. Some low-cost equipment has a simple overall structure. When unloading, it is often necessary to remove the connection between the winding slip shaft and the winding servo motor or other components, and then manually unload and move the rolls of materials. Some more advanced slitting machines have higher production costs and have certain auxiliary configurations when unloading, which can reduce the labor intensity of workers to a certain extent, but there are still problems such as long unloading time and low unloading efficiency.

[0003] After unloading, it is necessary to put multiple paper rolls for winding on the differential axis. At present, the paper rolls are basically installed and positioned manually. Some advanced slitting machine manufacturers have automatic loading and unloading systems, but they still install the paper rolls manually with laser-assisted positioning. Slitting machine manufacturers with slightly backward technology rely on manual installation and make the paper rolls longer, so that they can be inserted faster and do not need the positioning of the laser system.

[0004] Based on the above analysis, the current slitting machine has the following deficiencies in the process of winding and unloading and installing paper tubes: 1. In the process of winding and unloading, the degree of automation is low, and there is a lack of corresponding electro-hydraulic auxiliary systems. The labor intensity of workers in unloading is high and the unloading time is long, which affects the overall production efficiency. 2. In the process of installing paper tubes, manual operation is required, the loading efficiency is low, and the positioning accuracy is relatively low. The low accuracy leads to different sizes of each roll after winding. The wound rolls do not fall in the same position, and may be on the left or right. In addition, the length of the paper tube is long. In the entire production process, the length of each paper tube is redundant, and the manufacturing cost of the paper tube will increase. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology, and to provide an automatic winding and unwinding mechanism for a slitting machine with less manual operation, high production efficiency and high positioning accuracy, a slitting machine device with automatic winding and unwinding, and a method for using the above automatic winding and unwinding slitting machine device. In order to solve the above technical problems, the technical solution proposed by the present invention is as follows:

[0006] An automatic winding and unwinding mechanism comprises a base, a support frame, at least one unwinding assembly and at least one winding assembly, wherein the support frame is arranged above the base, and the unwinding assembly and the winding assembly are both arranged on the support frame. The unwinding assembly is used to receive the finished small coils from the slip shaft, and the winding assembly is used to install the winding paper roll on the slip shaft with high precision. By moving the support frame, the position adjustment of the unwinding assembly and the winding assembly can be realized to realize the unwinding and winding functions.

[0007] In the above-mentioned automatic winding and unwinding mechanism, preferably, it also includes a rotating seat for driving the support frame to rotate, the rotating seat is movably arranged on the base, the support frame is arranged on the upper part of the rotating seat, and the unwinding assembly and the winding assembly are arranged on different sides of the support frame (that is, the unwinding assembly and the winding assembly are not arranged in parallel). The above-mentioned rotating seat is used to make the support frame rotate relative to the base to adjust the position correspondence between the unwinding assembly and the winding assembly and the slip shaft to realize the unwinding or winding function. A servo motor drives a pair of bevel gears inside the rotating seat. The axis of the rotating shaft of the horizontal servo motor is horizontal, and the bevel gear changes the axis of movement to vertical to realize the rotation of the support frame. The rotating seat can slide relative to the base to adjust the distance between the unwinding assembly or the winding assembly and the slip shaft. The sliding between the rotating seat and the base is realized by the following components: a base track and a rotating seat driving source for driving the rotating seat to move on the base track. The base track can adopt a linear guide rail, and the rotating seat driving source can adopt a servo motor plus a ball screw. The unloading assembly and the winding assembly are preferably arranged on different sides of the support frame, and there is a certain angle between the two, preferably, the angle between the two is not less than 90 degrees, so as to ensure that the unloading and winding functions do not interfere with each other. When multiple unloading assemblies and winding assemblies are used, every two adjacent unloading assemblies and winding assemblies are arranged at the same height, and the corresponding relationship between the unloading assembly and the winding assembly and the slip shaft can be adjusted by the rotating seat, and there is no need to adjust the height.

[0008] In the above-mentioned automatic winding and unwinding mechanism, preferably, the unwinding assembly includes a support rod, which is arranged on the side of the support frame through a mounting seat, and a groove for inserting the end of the differential shaft is provided at one end of the support rod away from the mounting seat, and the size of the groove matches the size of the end of the differential shaft. The support rod is used to receive the coil from the differential shaft. When unwinding, since the movable support arm assembly needs to be lowered to facilitate moving the coil from the differential shaft to the support rod, the differential shaft is only supported by the fixed-drive assembly at this time. By providing a groove at the end of the support rod, when the support rod contacts the differential shaft, the end of the differential shaft will be inserted into the groove, which can play a role in supporting the differential shaft.

[0009] In the above-mentioned automatic winding and unwinding mechanism, preferably, the winding assembly includes a clamping part with an adjustable clamping opening size, the clamping part includes a fixed arm and a movable arm, the fixed arm is fixedly connected to the support frame, the movable arm is rotatably connected to the fixed arm (such as connected by a pin shaft), and the clamping part is provided with a movable arm driving source for driving the movable arm to rotate. The opening size of the clamping part can be achieved by driving the movable arm to rotate by the movable arm driving source. When the opening of the clamping part is small, the clamping part clamps the paper tube. When the opening of the clamping part is large, the clamping part loosens the paper tube, making it easy for the clamping part to retreat from the slitting machine body. The above-mentioned movable arm driving source can be a conventional driving device (such as a motor + gear). The above-mentioned fixed arm is fixedly connected to the support frame. In order to ensure the stability between the two, a support plate is provided between the fixed arm and the support frame.

[0010] In the above automatic roll-up and roll-off mechanism, preferably, a baffle positioning mechanism is provided in the clamping opening of the clamping portion, and the baffle positioning mechanism includes a guide rod and a baffle, and the baffle is slidably arranged on the guide rod, and the guide rod is arranged on the movable arm. The baffle can slide on the guide rod to facilitate adjustment of the distance between adjacent baffles, and then the position of the baffle is fixed by a fixing member, so as to facilitate accurate control of the installation accuracy of the paper roll.

[0011] In the above-mentioned automatic winding and unwinding mechanism, preferably, the baffle positioning mechanism also includes a fixing member, a notch is provided on the movable arm, a through hole and a fixing hole are provided on the baffle, the baffle is slidably arranged on the guide rod through the through hole, and the fixing member passes through the notch and is inserted into the fixing hole to fix the position of the baffle and the movable arm. The fixing member can fix the baffle with adjusted position to ensure the installation accuracy of the paper roll. The above-mentioned fixing member can be a screw rod, such as a screw hole is provided on the baffle, and the position of the baffle is fixed by the cooperation of the screw rod and the screw hole. When it is necessary to adjust the distance between adjacent baffles, the screw rod can be loosened, and the position adjustment of the baffle is more convenient.

[0012] As a general technical concept, the present invention also provides a slitting machine device with automatic winding and unwinding, including a slitting machine body, a slip shaft winding part is provided on the slitting machine body, the slip shaft winding part includes at least one slip shaft, and the slip shaft winding part is provided with the above-mentioned automatic winding and unwinding mechanism. The number and height of the above-mentioned unwinding components are the same as the number and height of the slip shafts, and the number and height of the winding components are the same as the number and height of the slip shafts. Taking the unwinding component as an example, when there are two slip shafts, two unwinding components are used, and the two unwinding components correspond to the slip shafts at the installation position of the support frame respectively, to ensure that the height of the two unwinding components corresponds to the height of the two slip shafts respectively.

[0013] In the above-mentioned slitting machine equipment, preferably, the slitting machine body is provided with a push plate assembly for pushing out and unloading the coiled material on the slip shaft, and the push plate assembly includes a push plate, a push plate track, and a push plate driving source for driving the push plate to move on the push plate track. The height of the above-mentioned push plate is preferably slightly lower than the height of the highest slip shaft, so that one push plate can achieve unloading of the coiled material on all slip shafts. The working process of the above-mentioned push plate driving source is as follows: the push plate is fixed to the push plate base by bolts, and four sliders are connected under the push plate base, which slide on the push plate track. Its power comes from the servo motor and converts the circular motion into linear motion through the ball screw.

[0014] In the above-mentioned slitting machine equipment, preferably, one side of the slip shaft is connected to the side plate of the slitting machine body through a fixed-drive assembly, and the other side of the slip shaft is connected to the side plate of the slitting machine body through a movable support arm assembly, and the movable support arm assembly includes a support arm and a support arm drive source for driving the support arm to move up and down; the automatic winding and unwinding mechanism is arranged on a side close to the movable support arm assembly. The fixed-drive assembly is used to fix and drive the slip shaft to rotate, and the rotation can be driven by a motor + gear. The movable support arm assembly can have two forms: supporting and lowering. When it is necessary to unload the roll and install the paper roll, the support arm is in a lowered form. When the unloading and installation of the paper roll are completed and the slitting machine body works normally, the support arm is in a supporting form. The above-mentioned support arm drive source can be a hydraulic cylinder or a pneumatic cylinder.

[0015] As a general technical concept, the present invention also provides a method for using a slitting machine device for automatic loading and unloading of rolls, comprising the following steps:

[0016] S1: Adjust the distance between adjacent baffles as needed, and then place the winding paper roll into the clamping part of the upper winding assembly;

[0017] S2: When the slitting of the main body of the slitting machine is completed and the roll needs to be unloaded, the support frame drives the unloading assembly to approach the winding part of the differential slip shaft, so that the support rod of the unloading assembly and the differential slip shaft are aligned and in contact (alignment means that the central axes of the two coincide), and under the push of the push plate assembly, the roll moves from the differential slip shaft to the support rod. During the movement of the roll, the support arm of the movable support arm assembly moves downward; when the unloading assembly is aligned with the differential slip shaft, the position of the unloading assembly is achieved by moving the support frame on the base, which can be completed with the help of conventional auxiliary positioning equipment;

[0018] S3: When the paper roll needs to be installed on the differential shaft after unloading, the push plate assembly retreats, the support frame rotates to make the paper roll on the upper roll assembly align with the differential shaft, and the support frame continues to drive the upper roll assembly to move toward the winding part of the differential shaft so that the paper roll is inserted into the differential shaft. At the same time, air is compressed in the differential shaft, and the differential ring supports the paper roll. Then the clamping part of the upper roll assembly releases the clamping force, and the support frame drives the upper roll assembly retreat; when the upper roll assembly is aligned with the differential shaft, the position of the upper roll assembly is achieved by moving the support frame on the base, which can be completed with the help of conventional auxiliary positioning equipment;

[0019] S4: The support arm of the movable support arm assembly rises upward, and the slitting machine body starts the next slitting operation.

[0020] The automatic winding and unwinding mechanism of the present invention changes the position correspondence of the unwinding assembly, the winding assembly and the slip shaft by moving and rotating the support frame in the steps of unloading and installing the paper tube to achieve different functions. When unloading, the mechanical parts are used to complete the automatic unloading function. Workers no longer need to move the rolls one by one from the slip shaft, which greatly reduces the labor intensity of the workers. When loading, the position of the paper tube is adjusted by the baffle to improve the installation accuracy of the paper tube. The whole process is closely connected, and the various parts work together to reduce the standby time. The work is highly automated and intelligent. The time for the slitting machine to stop slitting, wait for unloading and installation is less than one minute, which greatly improves the production efficiency. In the production work, the work that the workers need to complete is to remotely monitor the production status of the slitting machine and timely detect equipment failures that may occur during the production process. The labor intensity of the workers is low.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. The automatic winding and unwinding mechanism of the present invention comprises a winding unloading assembly and a winding loading assembly. By adjusting the positional relationship between the winding unloading assembly and the winding loading assembly, the winding unloading and winding loading functions can be conveniently realized. The entire winding unloading and winding loading process requires less manual operation and has lower labor intensity.

[0023] 2. The automatic winding and unwinding mechanism of the present invention can ensure the installation accuracy of the paper roll by placing the paper roll in the winding assembly, without using a wider paper roll, thus avoiding waste of paper rolls.

[0024] 3. The automatic coil loading and unloading mechanism of the present invention can adopt standardized production parts that are matched with automated production, thereby reducing the number of parts to be processed and ordered, and can reduce the overall production cost.

[0025] 4. The automatic rolling and unloading slitting machine equipment of the present invention realizes rolling and unloading through an automatic rolling and unloading mechanism, which saves time for rolling and unloading, and the whole rolling and unloading process is smoothly converted, thereby achieving higher production efficiency.
