Description

Technical Field

[0001] The utility model relates to a paper peeling control system, and more particularly to a paper peeling control system for a paper tube peeling machine in a paper production line. Background Art

[0002] In the papermaking industry, reeling is typically the final step in the papermaking process. During this step, the paper, after multiple drying and pressing steps, is calendered and wound into a parent roll. This roll is then packaged into finished paper of various specifications. However, because the amount of paper wound on each parent roll varies, a small amount of paper often remains on the parent roll after packaging. To remove this remaining paper from the parent roll, a paper stripping machine is typically used to transport the paper stripped from the parent roll to a broken paper conveyor for recycling, allowing this paper to be reused.

[0003] Figure 1 This is a side view of a traditional paper tube stripping machine, in which the paper tube stripping machine 2 is placed on a workbench 4, and below it is a broken paper conveyor belt 3. Figure 1 As shown in FIG. 1 , the paper remaining on the paper roll 1 enters the paper stripping machine 2 along the paper feeding direction indicated by the arrow F on the side of the paper stripping machine 2 so as to peel off the paper remaining on the paper roll 1. However, since the paper stripping speed of the paper stripping machine 2 is manually controlled by the operator based on experience, it is difficult to match it with the type of paper, and the paper roll 1 is often stuck in the paper stripping machine 2. Figure 1 The paper jam location A indicated by the bold arrow in the middle causes the production line to suspend operation or even shut down for maintenance.

[0004] One proposed solution is to equip the paper tube stripping machine with a paper peeling control system. However, this system only controls the equipment on the production line to run at a constant speed and cannot adjust the peeling speed appropriately for different paper types. Regardless of the paper type produced, the equipment on the line must operate at the pre-set speed. Even if the peeling speed hinders normal operation, the speed cannot be adjusted, seriously limiting the production line's adaptability.

[0005] In addition, the above paper peeling control system has the following disadvantages:

[0006] First, the inability to properly adjust the peeling speed still prevents paper jams from occurring during production, which can increase time and production costs because the paper cannot be peeled off cleanly and reused due to paper jams.

[0007] Once the paper stripping mechanism jams, the operator must climb the inclined surface of the stripping machine to remove the stuck paper. This slope is not only steep and smooth, but also lies beneath a metal conveyor belt chain with corrugated plates spaced approximately 8 cm apart. This is not only labor-intensive but also poses significant safety risks. A slip or fall from the slope could easily result in personal injury and lead to a safety accident.

[0008] Finally, it is obviously unrealistic to equip each type of paper with a dedicated paper peeling control system, which not only increases production costs but also does not conform to the modern concept of energy conservation and environmental protection.

[0009] To this end, the industry is currently in urgent need of designing a paper peeling control system that can be applied to various types of paper. This system can significantly reduce or even basically eliminate paper jams in paper peeling tube machines, reduce or even basically eliminate the safety risks of operator intervention, and make production line operations safer and more reliable. Utility Model Content

[0010] The purpose of the utility model is to provide a paper peeling control system that can be applied to various paper types. The system can significantly reduce or even basically eliminate paper jams in paper stripping tube machines, reduce or even basically eliminate the safety risks of operator intervention, and make the production line operation safer and more reliable.

[0011] The utility model relates to a paper peeling control system for a paper tube peeling machine, comprising:

[0012] a data input unit through which a user inputs one or more specified data of paper to be peeled off the paper roll; and

[0013] The speed control unit changes the paper stripping speed of the paper stripping tube machine based on a preset corresponding relationship according to the specified data received by the data input unit.

[0014] In the above technical solution, the term "data input unit" encompasses both components that actively input data, such as detectors, and components that passively input data, such as touch screens and control panels. Of course, the meaning of this term is not limited to the embodiments disclosed in this utility model, but also encompasses any embodiment with an equivalent effect as data input.

[0015] In the above technical solution, the term "speed control unit" is not limited to the frequency converter, but should also include any component with the same effect as speed control.

[0016] In the above technical solution, the term "prescribed data" refers to data related to the paper stripping speed of the paper stripping tube machine, including but not limited to the surface smoothness of the paper and / or the grammage of the paper.

[0017] In the above technical solution, the term "pre-set correspondence" refers to the peeling speeds of the paper stripping machine that are matched to different paper types, derived from extensive experimental results. Generally speaking, the smoother the paper surface, the faster the peeling speed; the heavier the paper weight, the slower the peeling speed. These correspondences are stored in the speed control unit, and the peeling speed of the paper stripping machine is adjusted based on these correspondences.

[0018] In the first embodiment of the present invention, the data input unit may be a touch screen, which displays two or more paper type option buttons for user selection, each of which is associated with at least one of the specified data of the paper.

[0019] In other words, each paper type option button corresponds to a peeling speed. In this embodiment, if eighteen paper types are determined based on their surface smoothness and grammage, eighteen paper type option buttons will be displayed on the touch screen, each corresponding to the peeling speed most suitable for that paper type. This allows the operator to easily select the desired button to set the peeling speed of the paper tube stripping machine.

[0020] In a second embodiment of the present invention, the data input unit may be a control panel having two or more paper type option buttons for user selection, each of which is associated with at least one of the specified data of the paper.

[0021] In other words, each paper type option button corresponds to a peeling speed. In this embodiment, if eighteen paper types are determined based on their surface smoothness and grammage, eighteen paper type option buttons are provided on the control panel, each corresponding to the peeling speed most suitable for that paper type. This allows the operator to easily select the desired button to set the peeling speed of the paper tube stripping machine.

[0022] In a third embodiment of the present invention, the data input unit may be a detector that detects one or more specified data of the paper and transmits the detected data to the speed control unit.

[0023] Unlike peeling speeds that are pre-associated with paper types, in this embodiment, the data input unit detects the paper type in real time and determines the peeling speed based on a pre-stored correspondence in the speed control unit. Compared to the first and second embodiments, this eliminates the need to pre-set multiple, sometimes up to eighteen, paper type options, eliminating the need for hardware devices such as a touchscreen or control panel, thus reducing equipment costs.

[0024] Preferably, the prescribed data is the surface smoothness of the paper or the grammage of the paper.

[0025] In another preferred embodiment, the speed control unit may be a frequency converter, which controls the paper stripping speed of the paper stripping tube machine by changing the frequency.

[0026] On the basis of the paper peeling control system according to the present invention, a speed fine-tuning unit may be further provided, which fine-tunes the paper peeling speed of the paper peeling tube machine based on the current paper peeling speed of the paper peeling tube machine.

[0027] In the first embodiment, the speed fine-tuning unit may include a speed adjustment knob such as displayed on a touch screen, which adjusts the paper stripping speed of the paper stripping tube machine steplessly based on a predetermined ratio of the current paper stripping speed of the paper stripping tube machine.

[0028] In a second embodiment, the speed fine-tuning unit may include a coarse speed adjustment button and a fine speed adjustment button displayed on the control panel, the coarse speed adjustment button coarsely adjusts the paper peeling speed of the paper peeling tube machine based on a first percentage of the current paper peeling speed of the paper peeling tube machine, and the fine speed adjustment button finely adjusts the paper peeling speed of the paper peeling tube machine based on a second percentage of the current paper peeling speed of the paper peeling tube machine, wherein the first percentage is greater than the second percentage.

[0029] In the above embodiment, the first percentage is preferably 10%, and the second percentage is preferably 1%. That is, the speed coarse adjustment button can roughly adjust the paper peeling speed of the paper peeling tube machine based on 10% of the current paper peeling speed of the paper peeling tube machine, and the speed fine adjustment button can finely adjust the paper peeling speed of the paper peeling tube machine based on 1% of the current paper peeling speed of the paper peeling tube machine.

[0030] The above design is conducive to the operator to make a certain degree of coarse or fine adjustment of the peeling speed based on the actual situation on the basis of the pre-set peeling speed, so as to increase the flexibility of peeling speed adjustment and further improve the safety of production line operation.

[0031] It can be seen that the paper peeling control system according to the present invention can obtain the following advantages:

[0032] (i) Significantly reduce or even eliminate the frequency of paper jams in the paper tube stripping machine, reducing the safety risk of human intervention and making the system operation safer and more reliable;

[0033] (ii) The automation level of the paper tube stripping machine control system is improved, thereby reducing labor costs;

[0034] (iii) Operators no longer need to enter hazardous areas to manually remove jammed paper, which essentially eliminates safety hazards and saves labor for operators.

[0035] (iv) the remaining paper on the paper core tube can be basically peeled off, saving production costs; and

[0036] (v) The transmission system has been improved to a frequency converter, which is more energy-efficient and environmentally friendly than before. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The working principle and technical effects of the paper peeling control system according to the present invention will be described below with reference to the accompanying drawings.

[0059] It should be understood that the embodiments described in this specification only cover some, not all, embodiments of the present invention. Based on the embodiments described in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0060] Unless otherwise defined, all technical and scientific terms used in this invention have the same meanings as those commonly understood by those skilled in the art in the art. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this invention.

[0061] For example, the terms "including" and "having," as well as any variations thereof, in the specification and claims of the present invention and the accompanying drawings are intended to cover non-exclusive inclusions. The singular forms "a," "the," and "the" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. The terms "first," "second," and the like in the specification and claims of this application are used to distinguish between different objects, rather than to describe a specific order or a primary-secondary relationship.

[0062] First embodiment

[0063] Figure 2 FIG. 1 is a side view of a first embodiment of a paper stripping control system for a paper tube stripping machine. Figure 2 As shown, the paper peeling control system includes: a touch screen 11 as a data input unit 10, through which a user inputs one or more specified data of the paper; and a frequency converter 21 as a speed control unit 20, which changes the paper peeling speed of the paper stripping tube machine 2 based on a preset corresponding relationship according to the specified data received by the touch screen 11.

[0064] In the above embodiment, the data input unit 10 can be an electrical control cabinet, and the touch screen 11 is installed on the outer surface of the electrical control cabinet, or it can be an electrical control cabinet with an openable door, and the touch screen 11 is installed inside the electrical control cabinet. When the touch screen 11 is powered on, it can display two or more paper type option buttons 12 for the user to select. Each of these paper type option buttons 12 is associated with at least one of the specified data of the paper. Figure 3 As shown in FIG, the figure shows a paper type option interface displayed on the touch screen, in which multiple groups of option buttons are displayed, and each group of option buttons consists of several option buttons.

[0065] Currently, paper specifications typically use surface smoothness or grammage. Generally speaking, the paper types used in the papermaking industry can be divided into three groups based on these specifications, with six typical grammages selected from each group, for a total of eighteen types. The table below lists the corresponding relationship between paper type and peeling speed. GC / AC / OC represent glossy coated paper, matte coated paper, and offset paper (uncoated paper), respectively, with their surface smoothness decreasing in descending order. Gramage (g) represents the mass per square centimeter of paper. For the same paper type (using GC as an example), a higher grammage corresponds to a greater thickness.

[0066]

[0067] As shown in the table above, based on practical experience, each paper type corresponds to a peeling speed that best matches it. These peeling speeds are stored in the inverter 21 and associated with the eighteen paper type option buttons 12 displayed on the touch screen 11. Specifically, the inverter 21 first determines whether the paper type is GC, AC, or OC, and then determines the corresponding peeling speed based on the paper weight. For example, if the paper type is matte coated (AC) and the paper weight is 80g, the peeling speed should be 70%, and so on. Generally speaking, under the same surface smoothness, the higher the weight, the faster the peeling speed is set; conversely, under the same weight, the higher the surface smoothness, the slower the peeling speed is set. Thus, when the operator sees the paper roll 1 containing the paper being fed into the paper tube stripper 2, they can press the paper type option button 12 corresponding to that paper type on the touch screen 11. The inverter 21 will then change the peeling speed of the paper tube stripper 2 based on the pre-set correspondence in the table. The operator can thus conveniently select a desired button to set the paper stripping speed of the paper stripping tube machine 2 .

[0068] Return to Figure 2The paper peeling control system further includes a speed fine-tuning unit 30, which can fine-tune the paper peeling speed of the paper peeling tube machine 2 based on the current paper peeling speed of the paper peeling tube machine 2. Figure 4 , a speed fine-tuning interface displayed on the touch screen is shown.

[0069] Specifically, the speed fine-tuning unit 30 includes a speed adjustment knob 31 displayed on the touch screen 11. The speed adjustment knob 31 continuously adjusts the paper stripping speed of the paper stripping tube machine 2 based on a predetermined percentage of the current paper stripping speed of the paper stripping tube machine 2. Alternatively, the speed fine-tuning unit 30 can be designed as a coarse speed adjustment button and a fine speed adjustment button displayed on the touch screen 11. The coarse speed adjustment button roughly adjusts the paper stripping speed of the paper stripping tube machine 2 based on, for example, 10% of the current paper stripping speed of the paper stripping tube machine 2, and the fine speed adjustment button finely adjusts the paper stripping speed of the paper stripping tube machine 2 based on, for example, 1% of the current paper stripping speed of the paper stripping tube machine 2. Of course, the paper stripping speed of the paper stripping tube machine 2 can also be adjusted based on other percentages of the current paper stripping speed. The range of adjustment is subject to the ability of those skilled in the art to implement.

[0070] Although the speed fine-tuning unit 30 is implemented as a knob or two buttons in this embodiment, it is also feasible to include only one button, or include two or more knobs, or three or more buttons in actual applications. Therefore, the number of control keys does not have a substantial impact on the scope of protection of the present invention.

[0071] In addition, the adjustment percentage of the above-mentioned button based on the current paper peeling speed of the paper tube peeling machine 2 only reflects the accuracy and speed of the manual adjustment of the button. Those skilled in the art can also change the upper or lower limit of the percentage according to actual conditions. Changes in these values ​​will not have any impact on the scope of protection of the present utility model.

[0072] Even with the same paper weight, different paper properties can occur under different operating conditions (such as temperature, humidity, and different production batches). Therefore, adding a manual adjustment function based on the preset peeling speed is very necessary for paper production. This design allows the operator to adjust the peeling speed to a certain extent based on the actual situation, increasing the flexibility of peeling speed adjustment and further improving the safety of production line operation.

[0073] The aforementioned paper peeling control system requires further hardware configuration improvements, including installation, wiring, PLC program modification, touch screen programming, inverter configuration and parameter modification, establishing intercommunication between the PLC, touch screen, and inverter, debugging, and optimization. As these improvements are not essential to the present invention, they will not be discussed here.

[0074] Second embodiment

[0075] Figure 5 FIG. 2 shows a second embodiment of a paper stripping control system for a paper tube stripping machine. Figure 5 As shown, the paper peeling control system includes: a control panel 13 as a data input unit 10, through which a user inputs one or more specified data of the paper; and a frequency converter 21 as a speed control unit 20, which changes the paper peeling speed of the paper stripping tube machine 2 based on a preset corresponding relationship according to the specified data received by the control panel 13.

[0076] In the above embodiment, the data input unit 10 can be an electrical control cabinet, with the control panel 13 mounted on its exterior surface. Alternatively, the data input unit 10 can be an electrical control cabinet with an openable door, with the control panel 13 mounted inside the cabinet. Two or more paper type option buttons 12 are mounted on the control panel 13 for user selection. Each of these paper type option buttons 12 is associated with at least one of the specified paper data. Unlike the first embodiment, these paper type option buttons 12 are not virtual buttons on the display interface, but are physical buttons.

[0077] Similar to the first embodiment, each paper type corresponds to a peeling speed that best matches that paper type. These peeling speeds are stored in the inverter 21 and associated with the eighteen paper type selection buttons 12 on the control panel 13. Thus, when the operator sees the paper roll 1 containing the paper being fed into the paper tube stripper 2, they can press the paper type selection button 12 corresponding to that paper type on the control panel 13. The inverter 21 then changes the peeling speed of the paper tube stripper 2 based on the pre-set correspondence in the table. This allows the operator to conveniently select the desired button to set the peeling speed of the paper tube stripper 2.

[0078] In addition, the paper peeling control system also includes a speed fine-tuning unit 30, which can fine-tune the paper peeling speed of the paper peeling tube machine 2 based on the current paper peeling speed of the paper peeling tube machine 2. The speed fine-tuning unit 30 includes a speed adjustment knob 31 provided on the control panel 13, which adjusts the paper peeling speed of the paper peeling tube machine 2 steplessly based on a predetermined ratio of the current paper peeling speed of the paper peeling tube machine 2. Alternatively, the speed fine-tuning unit 30 can be designed as a coarse speed adjustment button and a fine speed adjustment button provided on the control panel 13, the coarse speed adjustment button coarsely adjusting the paper peeling speed of the paper peeling tube machine 2 based on, for example, 10% of the current paper peeling speed of the paper peeling tube machine 2, and the fine speed adjustment button finely adjusting the paper peeling speed of the paper peeling tube machine 2 based on, for example, 1% of the current paper peeling speed of the paper peeling tube machine 2.

[0079] Although the speed fine-tuning unit 30 is implemented as a knob or two buttons in this embodiment, it is also feasible to include only one button, or include two or more knobs, or three or more buttons in actual applications. Therefore, the number of control keys does not have a substantial impact on the scope of protection of the present invention.

[0080] In addition, the adjustment percentage of the above-mentioned button based on the current paper peeling speed of the paper tube peeling machine 2 only reflects the accuracy and speed of the manual adjustment of the button. Those skilled in the art can also change the upper or lower limit of the percentage according to actual conditions. Changes in these values ​​will not have any impact on the scope of protection of the present utility model.

[0081] Even with the same paper weight, different paper properties can occur under different operating conditions (such as temperature, humidity, and different production batches). Therefore, adding a manual adjustment function based on the preset peeling speed is very necessary for paper production. This design allows the operator to adjust the peeling speed to a certain extent based on the actual situation, increasing the flexibility of peeling speed adjustment and further improving the safety of production line operation.

[0082] Third embodiment

[0083] In a third embodiment of the present invention, the paper peeling control system includes: a detector as a data input unit 10, which detects one or more specified data of the input paper; and a frequency converter 21 as a speed control unit 20, which changes the paper peeling speed of the paper peeling tube machine 2 based on a preset corresponding relationship according to the specified data transmitted by the detector.

[0084] In the above-described embodiment, because data input unit 10 is a detector, the paper type can be detected in real time, and the peeling speed can be determined in real time based on the correspondence pre-stored in inverter 21. Compared to the first and second embodiments, there is no need to pre-set multiple, or even up to eighteen, paper type selection buttons 12, eliminating the need for hardware devices such as touch screen 11 or control panel 13.

[0085] In addition, similar to the first and second embodiments, the third embodiment may also be equipped with a speed fine-tuning unit, so as to fine-tune the current paper stripping speed of the paper stripping tube machine when necessary.

[0086] While the operating principles and technical effects of the paper peeling control system according to the present invention have been described above in conjunction with preferred embodiments and accompanying drawings, those skilled in the art will recognize that the above examples are for illustrative purposes only and are not intended to limit the present invention. Therefore, modifications and variations of the present invention may be made within the spirit of the claims, and such modifications and variations will fall within the scope of the claims.
