Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of label printing, and particularly relates to a label printing device for the inner wall of a coil core within a shaft. Background Art
[0002] In the production processes of materials such as fibers, power battery separators, steel cord, films, tapes, and non-woven fabrics, a winding machine winds the materials at different speeds around various types of core tubes such as paper tubes and plastic tubes with corresponding widths. To meet product identification, quality control, traceability, and product-related regulatory requirements, labels are usually printed on the inner wall of the core tube by pasting paper labels or by means of laser, inkjet, printing, etc., for marking relevant information such as product name, model, production date, production station, etc.
[0003] The production process is divided into three steps:
[0004] The first step: Preparation of core tube materials: The core tubes required for production are sorted out by manual or a tube arranging machine and placed on a buffer transfer cart. Manually load the core tubes onto the corresponding winding machine shaft or hang them on an AGV cart with bearings to automatically load the tubes onto the winding machine shaft.
[0005] The second step: Material winding / slitting: The winding machine with the core tube loaded in the winding process winds the product in a circular motion according to the process until it is full. The slitting process achieves the required product width through mother roll slitting or unwind slitting.
[0006] The third step: Unloading and transfer: The full roll product is unloaded manually, or by a mechanical device with a plug bar and bearings, or by an AGV with bearings, and then transferred to the buffer transfer cart.
[0007] In current production practices, there are mainly two ways to achieve label operation on the inner wall of the core tube. One is a printing module such as laser, inkjet, etc. The printing nozzle is fixed in an external position at an inclined angle to align with the inner wall of the core tube before the core tube is transferred to the winding machine by a tube arranging machine, and the printing is realized on the inner wall of the core tube by moving the core tubes one by one, or after the product is unloaded from the winding machine or slit, the printing is carried out on the inner wall of the core tube one by one in the same way. In either case, it will separately increase the label printing process. The other way is that the paper labels are pre-printed, and are manually pasted onto the inner wall of the core tube one by one before the core tube is loaded onto the winding machine, or after the product comes down from the winding machine or is slit, and then manually pasted onto the inner wall of the core tube one by one. However, the manual operation method not only has a large labor intensity, but also has low efficiency and high error rate, and it is difficult to achieve traceability for each single roll of product.
[0008] Therefore, how to integrate the label printing on the inner wall of the core tube into the existing production process and efficiently and automatically complete the printing without increasing the operation process is the key to improving production efficiency. Summary of the Invention
[0009] In view of this, the purpose of the present invention is to provide a label printing device for the inner wall of a coil tube core within a shaft, aiming at the deficiencies of the prior art. By integrating the inner wall label printing into the existing operation process, the efficiency can be improved, the labor intensity can be reduced, and complete automation can be achieved.
[0010] To achieve the above object, the present invention adopts the following technical solutions:
[0011] A label printing device for the inner wall of a coil tube core within a shaft includes an air shaft. A hollow chamber is provided inside the air shaft. A linear driving mechanism and a marking module are arranged inside the hollow chamber. The linear driving mechanism drives the marking module to linearly move inside the hollow chamber. A strip-shaped hole communicating with the hollow chamber is formed on the outer side surface of the air shaft. The marking module faces the strip-shaped hole, and the moving direction of the marking module is the same as the length direction of the strip-shaped hole.
[0012] To better implement the present invention, further optimization is made to the above structure. The linear driving mechanism includes a sliding rod, a screw rod, and a moving seat. Both ends of the sliding rod are fixedly arranged on the air shaft. Both ends of the screw rod are rotatably arranged on the air shaft. The sliding rod and the screw rod are parallel to each other. The moving seat is slidably arranged on the sliding rod and is also threadedly connected to the screw rod. Rotating the screw rod can drive the moving seat to slide on the sliding rod. The marking module is arranged on the moving seat.
[0013] To better implement the present invention, further optimization is made to the above structure. The marking module is a laser printing head.
[0014] To better implement the present invention, further optimization is made to the above structure. A cable through hole is formed at the end of the air shaft.
[0015] To better implement the present invention, further optimization is made to the above structure. The marking module is detachably arranged on the moving seat.
[0016] To better implement the present invention, further optimization is made to the above structure. The length of the strip-shaped hole is the same as the length of the hollow chamber.
[0017] The present invention has the following beneficial effects compared with the prior art:
[0018] The label printing device for the inner wall of the coil core within the shaft provided by the present invention sleevs the core of the coil on the air shaft. A linear drive mechanism is arranged inside the air shaft to drive the marking module to move. The nozzle of the marking module passes through the strip-shaped hole opened on the air shaft to mark the inner wall of the core. During production, if there are multiple independent core stations on the air shaft at one time, the linear drive mechanism inside the air shaft can be used to control the movement of the marking module. After the nozzle of the marking module is accurately positioned with each core one by one, the label printing on the corresponding inner wall of the core is completed. This solves the problems in the prior art that installing the marking nozzle on the tube arranging machine will increase the process duration and the label time does not match the production time. It avoids marking in the tube arranging machine link, simplifies the operation process of the tube arranging machine, improves the efficiency, and solves the problem that the tube arranging and marking time is inconsistent with the actual production time of the product wound on the core. Moreover, compared with manual labeling, it has higher work efficiency, reduces labor intensity and will not make mistakes, and better meets the requirements of modern production and digital management in the factory.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] At present, there are two ways to mark the inner wall of the tube core:
[0029] 1. Automatic marking: In the tube core preparation stage, a coding station is added to the tube arranging machine to realize the printing of labels on the inner wall of the tube core. Since the tube core moves and the nozzle is fixed, in this way, the nozzle is fixed on the bracket and faces the inner wall of the tube core at a certain inclination angle. The paper tube moves on the tube arranging machine at a certain frequency, and the nozzle adjusts the coding rhythm to complete the marking of the inner wall of the tube core. At the specific time point of marking the inner wall of the tube core by the tube arranging machine, the product wound on the tube core has not entered the production process, so the marking time is not the real production time point of the product on the tube core.
[0030] 2. Manual labeling: The paper labels are pre-printed by a label printer, and then the workers stick the paper labels onto the tube cores one by one, which has low efficiency, heavy workload and is prone to errors.
[0031] Fibers, power battery diaphragms, steel cord, films, non-woven fabrics, tapes, etc. are all wound around a core and sold as the final product form. Therefore, how to integrate the printing of the inner wall label of the core into the existing production process and complete the printing efficiently and automatically without increasing the operation process is the key to production. In the production process of wound materials, unloading and transfer are essential links, and this link is usually performed by an air shaft to unload and transfer. By redesigning the internal structure of the air shaft 1 for unloading and transfer in this application, the problem of the need to add an additional marking operation process for manual pasting one by one and printing with a fixed inclination angle at the outer end of the nozzle is solved. The present invention integrates the inner wall label printing into the existing operation process, improves efficiency, reduces labor intensity, and can be connected to the background software system to achieve complete automated operation.
[0032] Please refer to Figures 1 - 3 , the label printing device for the inner wall of a coil core provided by the present invention includes an air shaft 1. A hollow chamber 101 is arranged inside the air shaft 1. A linear driving mechanism and a marking module 2 are arranged inside the hollow chamber 101. The linear driving mechanism drives the marking module 2 to linearly move inside the hollow chamber 101. A strip-shaped hole 102 communicating with the hollow chamber 101 is opened on the outer side surface of the air shaft 1. The marking module 2 faces the strip-shaped hole 102, and the moving direction of the marking module 2 is the same as the length direction of the strip-shaped hole 102. By using the linear driving mechanism to drive the marking module 2 to move, the nozzle of the marking module 2 passes through the strip-shaped hole 102 to mark the inner wall of the core 6.
[0033] As Figure 1 shown, the length of the strip-shaped hole 102 is the same as the length of the hollow chamber 101, and the marking distance of the marking module 2 is the same as the length of the hollow chamber 101. Moving the marking module 2 can mark the inner walls of cores 6 at different positions. If there are multiple independent coil 7 workstations on the air shaft 1 during production, the linear driving mechanism inside the air shaft 1 can be used to control the movement of the marking module 2, so that after the nozzle of the marking module 2 is accurately positioned one by one with the cores 6 of the coils 7, the label printing on the corresponding inner walls of the cores 6 is completed. The problems in the prior art that installing the marking nozzle on the tube arranging machine will increase the process duration, the label time does not match the production time, and it is impossible to print two-dimensional codes / barcodes due to the existing inclination angle are solved. Avoid marking in the tube arranging machine link, simplify the operation process of the tube arranging machine, improve efficiency, and at the same time solve the problem that the marking time in the tube arranging machine is inconsistent with the actual production time of the core product; moreover, it has a higher work efficiency than manual labeling, will not make mistakes, and better meets the requirements of modern factory production and digital management.
[0034] In this embodiment, the linear drive mechanism includes a slide bar 3, a screw rod 4, and a moving seat 5. Both ends of the slide bar 3 are fixedly arranged on the air shaft 1, and both ends of the screw rod 4 are rotatably arranged on the air shaft 1. The slide bar 3 and the screw rod 4 are parallel to each other. The moving seat 5 is slidably arranged on the slide bar 3, and the moving seat 5 is also threadedly connected to the screw rod 4. Rotating the screw rod 4 can drive the moving seat 5 to slide on the slide bar 3. The marking module 2 is arranged on the moving seat 5. By moving the moving seat 5, the marking module 2 is driven to align the nozzle on the marking module 2 with the corresponding die 6.
[0035] In this embodiment, the marking module 2 is a laser printing head. Of course, the marking module 2 can also adopt other various modules for automatically printing labels, such as inkjet printing heads. A cable through hole 103 is opened at the end of the air shaft 1, and the cable 8 connecting the marking module 2 passes through the cable through hole 103 to achieve connection. The print head of the marking module 2 is detachably arranged on the moving seat 5 and can be disassembled and replaced.
[0036] During use, the die 6 is sleeved on the outer side surface of the air shaft 1. By controlling the rotation of the screw rod 4, the moving seat 5 is moved on the slide bar 3 to accurately position the marking module 2 on the moving seat 5 with the die 6. Then, the nozzle on the marking module 2 prints labels on the inner wall of the corresponding die 6.
[0037] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
