Description

Paper tube flat roll machine control system

This creation is about an automated management system, especially a paper tube flat roll machine control system that reduces the burden of manpower and improves paper tube production efficiency and quality.

The known paper tube flat winder is used to roll paper tape into paper tubes, which are used in industrial reels, reels of daily necessities (such as tapes, plastic wrap, etc.), paper tubes, paper molds, etc. The known paper tube flat winder first unrolls the paper tape from a raw paper roll, fixes the front end of the paper tape on a winding drum, and rotates the winding drum to wind the paper tape layer by layer into a paper tube with thickness. In addition, the paper tape will be glued on the surface before winding, so that the wound paper tape can be tightly bonded layer by layer to improve the rigidity and toughness of the finished paper tube. When the paper tube reaches the required thickness, a cutting knife can be used to cut the paper tape, so that the finished paper tube exits the winding drum, and the cut end of the paper tape is fixed on the winding drum again, and the next paper tube is wound.

The process of producing paper tubes by the above-mentioned known paper tube flat roll machine includes multiple stages such as fixing paper belt, pressing paper, rolling, gluing, cutting, and material return. Between each stage, the operator must control the start and stop time of the winding drum, and adjust the timing of winding acceleration and deceleration. If different sizes of paper tubes are produced or different paper materials are replaced, the operation sequence needs to be modified, which increases the workload of the operator. In addition, once human error occurs, paper tube products that do not meet specifications or have unstable quality may be produced.

In view of this, the conventional paper tube flat roll machine still needs to be improved.

To solve the above problems, the purpose of this invention is to provide a paper tube flat roll machine control system that can reduce the burden of manpower.

The second purpose of this invention is to provide a paper tube flat roll machine control system that can avoid human operating errors.

Another purpose of this invention is to provide a paper tube flat roll machine control system that can improve the production efficiency and quality of paper tubes.

The directions or similar terms described in the entire text of this work, such as "front", "back", "upper", "lower", "inner", "outer", "side", etc., are mainly referenced to the directions of the attached drawings. Each direction or similar terms are only used to assist in the description and understanding of the various embodiments of this work, and are not used to limit this work.

The quantifiers "one" or "a" used in the components and parts described in this work are only for the convenience of use and to provide the general meaning of the scope of this work; in this work, they should be interpreted as including one or at least one, and the concept of a single number also includes the plural case, unless it is obvious that it means otherwise.

The control system of the paper tube flat-rolling machine of the invention comprises: a transmission module, a paper tape is output from a raw paper roll, the front end of the paper tape is fixed to the wheel surface of a winding roller, the winding roller rotates and rolls the paper tape, and the paper tape wound layer by layer forms a paper tube; a processing module, a gluing unit applies glue on the paper tape, a paper pressing wheel abuts against the wheel surface of the winding roller, the paper tape passes between the paper pressing wheel and the winding roller, and a cutting knife is located between the gluing unit and the paper pressing wheel; a detection module, detecting that the transmission module generates a measurement signal, and the measurement signal It includes a winding length, which is the cumulative length of the paper tape wound around the winding roller; and a control module, which is coupled to the transmission module, the processing module and the detection module respectively. The control module receives the measurement signal, compares the winding length with the total winding length to determine the winding stage of the paper tube, and generates a control signal according to the determination result to control the transmission module and the processing module to perform several corresponding tasks, including adjusting the rotation speed of the raw paper roll and the winding roller, and raising and lowering the gluing unit, the paper pressing wheel and the cutter.

Based on this, the paper tube flat-rolling machine control system of this invention can determine the stage of the paper tube flat-rolling process by monitoring the output length of the paper tape and comparing it with the total winding length. It is used to control the transmission module and the processing module to perform work at the correct time and sequence. When producing paper tubes of different sizes or changing different paper thicknesses, only the parameters need to be adjusted to automatically execute the production process, which has the effects of reducing the burden of manpower, improving production efficiency and enhancing product quality.

The transmission module has several guide wheels, which are located between the raw paper roll and the winding roller, and the paper tape is transported to the winding roller through the several guide wheels. In this way, the several guide wheels are used to guide the paper tape to be transported stably, so that the paper tape can be kept flat and with uniform tension, and it has the effect of avoiding defects such as wrinkles or gaps between layers when the paper tape is wound.

The take-up roller has a plurality of inflatable spokes, one end of each inflatable spoke abuts against the axis of the take-up roller, and the other end radially abuts against the inner side of the wheel surface of the take-up roller. Each inflatable spoke is inflated and stretched, so that the diameter of the take-up roller increases and the wheel surface slightly expands outward. In addition, each inflatable spoke is deflated and shortened, so that the wheel surface of the take-up roller shrinks inward. In this way, the wheel surface expands outward to make the paper tape more tightly wound and less likely to fall off, and the wheel surface shrinks inward to create a gap between the inner ring surface of the paper tube and the wheel surface of the winding roller, making it easier to separate and unload the paper, which has the effect of improving production efficiency and stabilizing product quality.

The control signal is used to control the several tasks including switching the expansion and contraction of the several inflation strips. In this way, the start and completion of winding can be switched automatically, which has the effect of reducing the burden of manpower.

The detection module has a length encoder, a rotation counter, an ultrasonic sensor, and a tension gauge. In this way, the detection module can monitor the conveying and winding of the paper tape, and has the effect of preventing deviations in the manufacturing process.

The measurement signal also includes the number of revolutions of the take-up roller, the remaining thickness of the raw paper roll, the accumulated winding thickness of the paper tape, and the tension of the paper tape during transportation. In this way, the control module can judge the production progress and production line status based on the measurement signal, which has the effect of improving production efficiency and avoiding manufacturing errors.

The control module calculates the total winding length according to the thickness of the paper tape, the diameter of the winding roller and the target thickness of the paper tube. Thus, the target thickness divided by the thickness is the number of winding layers required for the paper tube. The diameter is divided by the thickness correction to calculate the circumference of each winding of the paper tape. The total winding length is obtained by adding up the circumference of the paper tube layer by layer. The control module can automatically adjust the automated process conditions by modifying the process parameters, which has the effect of reducing the burden of manpower and avoiding human errors.

[Figure 3] An enlarged view of the local structure shown in Figure 2.

In order to make the above and other purposes, features and advantages of this creation more clearly understood, the following article specifically cites the preferred implementation examples of this creation and provides detailed descriptions with the attached drawings; in addition, the same symbols in different drawings are considered the same and their descriptions will be omitted.

Please refer to Figure 1, which is a preferred embodiment of the control system of the paper tube flat roll machine of the present invention, which includes a transmission module 1, a processing module 2, a detection module 3 and a control module 4. The transmission module 1, the processing module 2 and the detection module 3 are respectively coupled to the control module 4. The detection module 3 detects the transmission module 1 to generate a measurement signal M and transmits it back to the control module 4. The control module 4 provides a control signal C to operate the transmission module 1 and the processing module 2.

Referring to FIGS. 2 and 3 , the transmission module 1 may include a raw paper roll 11, a take-up roller 12, and a plurality of guide wheels 13. A paper tape P is drawn out from the raw paper roll 11 and unfolded, so that the front end of the paper tape P is fixed to the wheel surface of the take-up roller 12. When the take-up roller 12 rotates, the paper tape P of the raw paper roll 11 can be pulled to the The winding roller 12 is wound layer by layer, and the guide wheels 13 can be located between the raw paper roll 11 and the winding roller 12 to guide the paper tape P to be stably transported to the winding roller 12, so that the paper tape P can be kept flat and with uniform tension to avoid defects such as wrinkles or gaps between layers when the paper tape P is wound.

As shown in FIG. 3 , the take-up roller 12 may have a plurality of inflatable radial strips 121, one end of each inflatable radial strip 121 abuts against the axis of the take-up roller 12, and the other end radially abuts against the inner side of the wheel surface of the take-up roller 12. When the paper tape P is wound around the wheel surface of the take-up roller 12, each inflatable radial strip 121 may be inflated and stretched, so that the diameter of the take-up roller 12 increases and the wheel surface slightly expands outward. The expansion can make the paper tape P roll more tightly and not easy to fall off; when the paper tape P is rolled to form a paper tube, each of the inflation strips 121 can be deflated and shortened, so that the wheel surface of the winding roller 12 shrinks inward, and a gap can be generated between the inner annular surface of the paper tube and the wheel surface of the winding roller 12, so that the paper tube can be easily separated and unloaded, which has the effect of quickly taking out the paper tube and continuing the next winding operation.

Referring to FIGS. 2 and 3 , the processing module 2 may include a gluing unit 21, a paper pressing wheel 22, and a cutter 23. The gluing unit 21 is preferably located behind the plurality of guide wheels 13 and before the paper tape P is wound around the winding roller 12. The gluing wheel 21a rolls on a glue box 21b below to be coated with glue, and the paper tape P passes over the gluing wheel 21a. The glue coated on the gluing wheel 21a can be continuously applied to the paper tape P during the rolling process. The paper pressing wheel 22 is The paper tape P is close to the wheel surface of the take-up roller 12, and passes between the paper pressing wheel 22 and the take-up roller 12. The paper pressing wheel 22 can press the paper tape P to closely adhere to the wheel surface of the take-up roller 12 or the last wound paper tape P; the cutter 23 is preferably located between the gluing unit 21 and the paper pressing wheel 22. When the paper tape P is output to a sufficient length, the gluing unit 21 stops gluing first, and then the cutter 23 cuts off the paper tape P. The take-up roller 12 unloads the remaining paper tape P after winding it.

Please refer to Figures 1 to 3. The measurement signal M generated by the detection module 3 includes a winding length, which is the cumulative length of the paper tape P wound around the winding roller 12. The detection module 3 can be located on the conveying path of the paper tape P through a length encoder to measure the length of the paper tape P passing through the length encoder in real time. The winding length can be obtained by deducting the distance from the length encoder to the winding roller 12. The length encoder can be located close to the raw paper roll 11 or close to the winding roller 12, or between the guide wheels 13. This invention is not limited to this.

The detection module 3 may also have sensing elements such as a rotation counter, an ultrasonic sensor, and a tension gauge to monitor the working condition of the transmission module 1. The measurement signal M may also include: the number of rotations of the winding roller 12, the remaining thickness of the raw paper roll 11, the winding cumulative thickness of the paper tape P, the tension of the paper tape P during the conveying process, etc. However, this invention is not limited to the above-mentioned sensing elements and their measurement data.

By inputting the thickness of the paper tape P, the diameter of the take-up roller 12 and the target thickness of the paper tube to the control module 4, a total winding length can be calculated. The control module 4 then compares the winding length of the measurement signal M with the total winding length to know the stage of the paper tube flat rolling and generate the control signal C, which is used to control the working sequence of the transmission module 1 and the processing module 2 in the flat rolling process, for example: adjusting the rotation speed of the raw paper roll 11 and the take-up roller 12, switching the expansion and contraction of the several inflation strips 121, and raising and lowering the gluing unit 21, the paper pressing wheel 22 and the cutter 23.

For example, in the several stages of a paper tube winding process, an initial stage is to fix the front end of the paper tape P on the wheel surface of the winding roller 12. At this time, the winding length can be reset to zero, and the several inflation strips 121 of the winding roller 12 are inflated by operating the control signal C to control the gluing unit 21 and the cutter 23 to leave the surface of the paper tape P, and the paper pressing wheel 22 to be close to the wheel surface of the winding roller 12.

In a first stage, the control signal C operates the take-up roller 12 to slowly wind one circle, that is, after the take-up length reaches a circumference of the wheel surface of the take-up roller 12, the take-up roller 12 stops rotating, and then the control signal C operates the glue unit 21 to contact the surface of the paper tape P.

In a second stage, the control signal C operates the winding roller 12 to wind at high speed until the winding length reaches the total winding length minus a deceleration distance, and then the winding roller 12 switches to slow winding. In this embodiment, the deceleration distance is six meters, but this invention is not limited to this.

In a third stage, when the winding length reaches the total winding length minus the distance from the gluing unit 21 to the cutter 23, the control signal C operates the gluing unit 21 to leave the surface of the paper tape P, and the winding length reaches the total winding length. Then, the control signal C operates the winding roller 12 to stop rotating, and the cutter 23 cuts the paper tape P.

In the fourth stage, the control signal C operates the take-up roller 12 to slowly wind the end of the paper tape P and then stop rotating. The control signal C then operates the several air expansion strips 121 of the take-up roller 12 to deflate, and the paper pressing wheel 22 leaves the wheel surface of the take-up roller 12, and opens a material return door G, so that the completed paper tube can be withdrawn from the take-up roller 12.

In summary, the control system of the paper tube flat-rolling machine of this invention can determine the stage of the paper tube flat-rolling process by monitoring the output length of the paper tape and comparing it with the total winding length. It is used to control the transmission module and the processing module to perform work at the correct time and sequence. When producing paper tubes of different sizes or changing different paper thicknesses, only the parameters need to be adjusted to automatically execute the production process, which has the effects of reducing the burden of manpower, improving production efficiency and enhancing product quality.
