Description

Membrane cutting machine detection method

The invention relates to a film cutting machine detecting method, in particular to a film cutting machine detecting method for detecting whether a correspondence relationship between a film cutting machine blade film and a bottom paper, a supplementary material and the like is correct.

Generally speaking, after the self-adhesive sticker finishes the surface material printing and the surface material is back-adhesive to the release paper (substrate), the processing industry needs to further cut the surface material to leave a tearable surface material. The cutting mark, which is the film cutting, allows the user to freely remove the surface material with the printed pattern and the typeface from the release paper.

Membrane cutting is a very fine cutting process, so the model and thickness selection of the knives (or knives) need to be extremely precise and correspond to the thickness of the material to be cut in order to perform the correct film cutting to complete the processing. Otherwise, even if there is only a gap of 1 mm in size, it is still a thousand miles away. The helplessness is that the wrong choice of the film before cutting is a kind of human error that often occurs but is difficult to avoid. If the wrong knife is used, the efficiency of the film is checked beforehand or the progress of the film cutting is delayed. Because the wrong knife film is used, the entire film cutter is damaged, resulting in unnecessary equipment warranty costs.

The reason is that the present inventors have felt the above-mentioned problems, and have devoted themselves to research and cooperated with the application of the theory, and finally proposed a present invention which is rational in design and effective in improving the above-mentioned defects.

The object of the present invention is to provide a film cutting machine detecting method, which solves the problem of frequent selection errors of the knife film and avoids the incorrect selection of the film film. Use to bring unnecessary equipment damage.

In order to achieve the above object, the present invention provides a film cutting machine detecting method, the film cutting machine comprising at least a tool holder and a processing seat corresponding to the tool holder, the knife holder is provided with a knife film, and the processing seat is provided with a bottom paper And a make-up material comprising a side material and a release paper, the film cutting machine detecting method comprising the steps of: inputting a film cutting parameter, the film cutting parameter comprising a knife film height value corresponding to the knife film, Corresponding to the thickness of the backing paper of the backing paper and a value of the thickness of the filler corresponding to the feeding material; generating a corresponding first film contact stroke for the film cutting parameter ratio; a knife film is moved toward the bottom paper to perform a knife inspection and a second knife film contact stroke is recorded when the knife film contacts the base paper; comparing the first blade film contact stroke with the second blade film contact stroke; and generating a Primary knife test results.

Through the above technical content, the staff can effectively avoid the misjudgment of the selection of the knife film, and simplify the pre-inspection and confirmation steps of the knife film, promote the working efficiency of the film cutting, and ensure that the film cutting machine does not use the wrong knife film. And caused damage.

For a better understanding of the features and technical aspects of the present invention, reference should be made to the accompanying drawings.

Referring to FIG. 1 and FIG. 5 , the present invention provides a film cutting machine 1 . The film cutting machine 1 includes at least one tool holder 10 and a machining seat 20 corresponding to the tool holder 10 . a knife film 111, the knife film 111 is located on a knife seat 11 of the knife seat 10, and the processing base 20 is provided with a bottom paper 30 and a supplementary material 40. The bottom paper 30 comprises a side material 31 and a release paper 32, and the film cutting machine is used. When detecting, the seat 10 equipped with the knife film 111 can be in the downward cutting direction F1 Or the return direction F2 is moved up and down, and if the knife holder 10 is moved up and down during the film cutting process, the bottom paper 30 on the processing base 20 is continuously conveyed along the paper feed direction F3.

The film cutting machine detecting method of the present invention comprises the steps of: inputting a film cutting parameter, wherein the film cutting parameter comprises a knife film height value corresponding to the knife film 111, a bottom paper thickness value corresponding to the backing paper 30, and a corresponding The value of the thickness of the filler 40 of the filler 40 (S101); the film cutting parameter is compared with a first film contact stroke for the film cutting parameter database (S103); the knife film 111 is moved toward the bottom paper 30 for performing a process of detecting the knife, and recording a second blade contact stroke when the blade contacts the liner 30 (S105); comparing the first blade contact stroke with the second blade contact stroke (S107); and generating a primary knife Membrane detection result (S109).

The first knife contact stroke corresponds to the contact distance L1 of Figure 1, and please refer to the following list 1, assuming that the knife height value is 9.18 mm, the thickness of the filler is 0.06 mm, and the value of the thickness of the filler is 0.89. PCT, the above three membrane cutting parameters are input into the membrane cutting parameter database and the corresponding first membrane contact stroke is generated. If the first membrane membrane contact stroke is expected to be about 9.781473617 mm, the approximate number is 9.78 mm. However, without limitation to this, the knife film 111 can be moved toward the bottom paper 30 to perform the operation of the blade, and the second blade contact stroke is recorded when the blade contacts the liner 30, and the first blade is passed through the first blade. After the comparison between the film contact stroke and the second blade contact stroke, a primary knife film detection result is generated, and the second blade film contact stroke obtained after the blade is contacted with the first blade film of the film cutting parameter database. The stroke is consistent. If there is any inconsistency, for example, the value of the knife height is 9.0 when the wrong knife is taken (but the input is still 9.18 when actually inputting the die cutting parameter database), and the primary knife test result R1 is given. The detection result is displayed and the setting size error is displayed. At this time, it is necessary to check again the type and type of the knife film 111, whether the selected backing paper 30 is wrong, and whether the selected feeding material 40 is correct, and the wrong knife is taken again. The film 111 or the additive 40 takes the most frequently occurring error; if it is consistent, the primary knife film detection result shows that the film cutting machine 1 is in standby state, however, the numerical values in the following examples are only used as an example for the embodiment, and may not be used. The scope of the invention is not intended to limit the scope of the invention.

The value of the knife film height, the thickness of the backing paper, and the value of the thickness of the material can be input into the film cutting parameter database before the film cutting test for the first time, and the three values are set. The first blade contact stroke is detected, and the obtained first blade contact stroke is recorded to the film cutting parameter database to correspond to the blade height value, the base paper thickness value, and the additive thickness value, so that When the film cutting work of the same specification is performed again in the future, the second film contact stroke obtained by the tool can be generated by comparing the value of the blade height value, the thickness of the backing paper, and the thickness of the thickness of the die cutting parameter database. The first knife film contacts the stroke to judge.

Referring to FIG. 1 , FIG. 2 and FIG. 4 , preferably, the first blade contact stroke and the second blade contact stroke further correspond to the two first offsets respectively. The angle of rotation of the heart drive shaft 50, and the first eccentric portion 52 of the first eccentric drive shaft 50 is responsible for rotating and rotating the second eccentric portion 62 of the second eccentric drive shaft 60 through the shaft 70, the second eccentric drive shaft 60, by means of a connecting member 61 disposed on the bottom rod 22 of the processing base, the knife seat 10 is driven and interlocked, and the knife film 111 is further driven to move to the processing base 20 on which the bottom paper 30 and the filler 40 are laid, and the knife is simultaneously moved. The film 111 is in contact with the bottom paper 30. At this time, as for the first eccentric drive shaft 50, since the first blade contact stroke or the second blade contact stroke are respectively rotated by the first eccentric drive shaft 50 by different angles, Therefore, comparing the first blade contact stroke with the second blade contact stroke corresponds to comparing the two rotation angles of the first eccentric drive shaft 50, and since the first eccentric drive shaft 50 can be directly or indirectly driven by the first A servo motor S1, the rotation angle of the first eccentric drive shaft 50 can be recorded by the signal fed back when the first servo motor S1 is actuated, and preferably, the first eccentric drive shaft 50 can be driven by a main drive shaft 80. Main gear 81 drives the first eccentric transmission The first gear 51 is located at a non-eccentric portion (not labeled) on the first eccentric drive shaft 50, and the first gear 51 is used to make the first eccentricity with the interlocking of the main gear 81 instead of eccentrically The drive shaft 50 rotates. However, the portion of the first eccentric drive shaft 50 that actually produces the eccentric drive is the first eccentric portion 52. Therefore, it can be seen from the above that the stroke of the first blade contact stroke or the second blade contact stroke is , not necessarily only by the length, or by the angle of rotation of the first eccentric drive shaft 50, so if the angle of rotation of the first eccentric drive shaft 50 is used to indicate the first blade contact stroke or the second blade This method should still be indiscriminately within the scope of the invention when contacting the stroke.

Further, the film cutting parameter further corresponds to a first blade cutting stroke, and the first cutting stroke can be constructed in the film cutting parameter database by a method similar to the above-mentioned film cutting parameter and the first blade contact stroke, when the film is cut When the 111 is in contact with the bottom paper 30, the step of cutting the bottom paper 30 according to the first film cutting stroke is further included. . When the knife film 111 cuts the bottom paper 30, the step of recording a second film cutting stroke of the knife film 111 by using a second servo motor S2 is further included, but the first servo motor S2 can also be used to record the second. The cutting speed of the knife film is not limited to the second servo motor S2. It is straightforward that when the knife film 111 cuts the bottom paper 30 downward, the knife film 111 will be because of the surface material of the bottom paper 30. 31 or contact with different materials of the release paper 32 to feed back different cutting stress signals to the second servo motor S2, so when the bottom paper 30, the filler 40 and the knife film 111 are all correct, the cutting stress of the second blade cutting stroke The signal will theoretically be the same as the first blade cutting stroke. However, if the specifications of either the backing paper 30, the filler 40 or the blade 111 are incorrect, the cutting stress signal may be delayed or early. It means that the material is the same as the face material 31 and the release paper 32 but different thickness (such as the thickness of the face material L2, the thickness L3 of the backing paper and the thickness L3 of the release paper minus the value of L2); or the stress that can be fed by the cutting stress signal Inconsistent, this means that the facestock 31 and the release paper 32 have at least One of the materials is inconsistent.

And at least by comparing the values of the first blade cutting stroke and the second blade cutting stroke to further reflect the individual thicknesses of the face material 31 of the backing paper 30 and the release paper 32 to be aligned and displayed once. The results of the graded membrane test are shown in the example of Table 2 below.

As is clear from Table 2, although the thickness of the base paper 30 is the same, there is still a difference in the individual thicknesses of the face material 31 and the release paper 32. It is easy to judge the wrong part of the film cutting machine inspection process.

The cutting stress signal generated by the different materials on the knife film 111 or the first servo motor S1 or the second servo motor S2 during cutting can be used to determine the difference in materials.

Referring to FIG. 1 , FIG. 3 and FIG. 4 , the individual thicknesses of the bottom paper 30 , the face material 31 or the release paper 32 can also be expressed by the rotation angle of the second eccentric transmission shaft 60, so when detecting, The first blade cutting stroke and the second blade cutting stroke also correspond to two rotation angles of the second eccentric transmission shaft 60, respectively, and the second eccentric transmission shaft 60 is used for rotating to interlock the blade seat 10 to drive the blade 11 The knife film 111 is located at an effective cutting blade position, and at the same time, the knife film 111 is effectively cut to the bottom paper 30. Therefore, comparing the first blade cutting stroke with the second blade cutting stroke corresponds to comparing the second eccentric transmission shaft 60. At two angles of rotation, this effective cutting generally means that the cutting of the face material 31 can be performed only, but not the entire release paper 32, in other words, the partial cutting of the bottom paper 30, however, In some cases, the film cutting process still requires a complete cut of the face material 31 of the backing paper 30 and the release paper 32, so effective cutting includes at least the above two conditions.

Therefore, referring to FIG. 3, the present invention further includes a fine adjustment of the rotation angle of the second eccentric transmission shaft 60 corresponding to the second blade cutting stroke by an increase or decrease of 0 to 90 degrees with respect to the horizontal 0 degree. (According to the mathematical angle M1 of FIG. 3) to generate a cutting correction angle, and the cutting correction angle can be used to correspond to the cutting depth of the knife film 111 to the backing paper 30 and determine the knife pressure of the knife film 111, and the eccentric crankshaft radius R represents the crankshaft radius of the second eccentric drive shaft 60, and the rotation of the second eccentric drive shaft 60 is the change of the starting position of the blade 111 (Fig. 1) on the seat 10 as RR ^* sinM1 (that is, the projection on the Y-axis), if the second eccentric drive shaft 60 takes the mathematical angle M1 to 30 degrees, the true position of the knife 111 on the Y-axis will be RR ^* sin30 = 0.5R, this one 0.5R determines that the cutting correction angle of the second eccentric drive shaft 60 also determines the tool pressure and the cutting depth.

Preferably, the above-mentioned cutting depth may be the thickness of the face material 31 or may be the sum of the thickness of the face material 31 and the release paper 32, that is, the thickness of the backing paper L3 of FIG. Therefore, it can be understood that the cutting correction angle can be used to adjust the cutting depth and the knife pressure of the knife film 111 to the bottom paper 30 to achieve an optimal effective cutting, and the cutting correction angle can also be recorded in the above-mentioned film cutting parameters. The data base, so that the next time the same film cutting process is performed, once the three sets of film cutting parameters are input, the cutting angle of the second eccentric drive shaft 60 can be directly set to the second film. After the contact angle test is passed, the film cutting process can be directly performed. Obviously, the invention can effectively improve the efficiency and correctness of the film cutting process. If the film cutting process cannot be smoothly cut at this time, it may be necessary to re-cut the first knife. The film contact stroke is finely adjusted (achieved by finely adjusting the rotation angle of the first eccentric drive shaft 50 by the first servo motor S1) or finely adjusted by the cutting correction angle (using the second servo motor S2 and the second eccentric drive shaft) The rotation angle of 50 is finely adjusted to achieve).

Referring to FIG. 1 and FIG. 3, preferably, the present invention further includes a booting process, the booting process further includes a booting detecting step, and the booting detecting step is configured to detect the eccentricity of the second eccentric shaft 60 (not shown) The reference numeral, or the center of the second eccentric portion 62, which is not labeled, is located at 0 degrees of the mathematical angle M1 (the mechanical angle M2 is 90 degrees, or 0 degree on the X-axis).

Preferably, if the center of the second eccentric portion 62 is not at the 0 degree position of the mathematical angle M1, the starting procedure further includes adjusting the mathematical angle M1 to 0 degrees of the eccentricity (not labeled) of the second eccentric drive shaft 60 ( The position of the mechanical angle M2 to 90 degrees), or adjust the mathematical angle of the first eccentric drive shaft 50 from M1 to 270 degrees (machine The position of the mechanical angle M2 to 0 degrees), and an instrument zero calibration operation for the subsequent film cutting work.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent changes and modifications made by the scope of the present invention are covered by the scope of the present invention. .
