This happens when the wallpaper A is set improperly by pressing it against the glue roller (112) to which glue B is attached, passing it over the error roller (114), and closing the upper frame (102). ..
Further, as a mechanical factor, it occurs when the rubber on the surface of the measuring roller (8) or the feeding roller (9) is worn or hardened due to aging during use by the operator.
In such a case, the person in charge of maintenance adjusts the maintenance of the holding springs (not shown) at the left and right shaft ends of the measuring roller (8) at the interior construction site or the nearest sales office. It is difficult to confirm whether it was successful.
Against such a background, the function to detect that the position of the wallpaper A at the time of gluing is shifted and skewed, and the adjustment work of the measuring accuracy of the automatic wallpaper gluing machine (101) of the maintenance staff. An automatic wallpaper gluing machine (101) having a function of assisting the above is desired, but has not yet been embodied.

A scale sticker (53) provided with 17 scale lines such as a scale line (54a) is attached, and the 17 scale lines such as the scale line (54a) are carried on the wallpaper end H of the wallpaper A. In addition, it is configured to be located on the front side of the upper blade (28) and the lower blade (29).
Further, 17 scale lines such as the scale line (54a) are provided at intervals of 10.0 mm, and in the image data taken by the camera module (51), 250 pixels exist between 10.0 mm. As described above, the mounting height and the front-back direction of the camera module (51) in the vertical direction are determined by the shape and dimensions of the camera module mounting plate (52).
Further, in the lateral direction (width direction of the wallpaper A), the wallpaper end portion H before the side edge portion I is cut by the upper blade (28) and the lower blade (29), and the scale such as the scale line (54a). The operator loosens the blade position adjusting screw (41) and the blade position fixing plate (40) so that the camera module (51) can capture an image including lines, and the position of the image captured by the camera module (51). Is configured so that it can be aligned while looking at the display operation unit (134) so that it can correspond to various wallpapers A having different widths.

The sequence in which the calculation unit (33) of the automatic wallpaper gluing machine (1) of the present invention detects the skew of the wallpaper A will be described with reference to the flowchart of FIG.
In the processing MTP 1, the "set glue length" and the "set number of sheets" are set by the operator from a plurality of key switches (not shown) of the display operation unit (34), and the calculation unit (33) is set to "setting". "Glue length" is stored in the variable J.
When the start switch (not shown) is pressed, the arithmetic unit (33) initializes the parameters necessary for executing the process, and is the parameters used in the process MTP 4, parameter t, parameter L, and parameter s. , Parameter M is also initialized.

In the processing MTP2, the calculation unit (33) detects the position of the wallpaper end portion H before starting the motor (24).
The range shown by the alternate long and short dash line in FIG. 6 is the range of the image taken by the camera module (51).
The calculation unit (33) jumps over the scale line (54e) from the wallpaper end portion H and obtains the distance to the scale line (54d).
As for the method, for example, assuming that the distance from the wallpaper end H to the scale line (54d) is 17.0 mm in FIG. 6, 425 pixels exist between the wallpaper end H and the scale line (54d) in the image data. .. (This is because, as described above, the camera module (51) is arranged so that one pixel is 0.04 mm.)
The calculation unit (33) reads the number of pixels of the image data and reads it.
As 0.04 mm x 425 = 17.0 mm,
In the array D (n) for storing the distance from the wallpaper end H to the scale line (54d),
It is stored in the storage unit (35) as D (0) = 17.0 mm.
D (0) = 17.0 mm, which is the distance from the wallpaper end H to the scale line (54d) before the start of transportation, is defined as the “wallpaper end origin position”.
Subsequently, the calculation unit (33) issues a command to the motor control unit (36) to start the motor (24), and starts the transfer of the wallpaper A.

In the processing MTP3, the calculation unit (33) counts the scale signal (30) generated by the scale unit (18) and calculates the “execution glue length” of the wallpaper A which is conveyed.
As the first counter,
The parameter t is set to t ← t + 1, and the scale signal (30) is added each time it is counted.
The "execution glue length" L is determined based on L = t × P, (P is the moving distance of the wallpaper A when one measuring signal (30) is counted (the diameter of the measuring roller (8)). It is calculated as a constant)).
Further, as a second counter for determining the timing for detecting the deviation Z,
The parameter s is set to s ← s + 1, and the scale signal (30) is added each time it is counted, and the length M corresponding to the second counter s is obtained as M = s × P.

In the processing MTP 4, the calculation unit (33) determines whether or not the length M has reached a predetermined length.
In the automatic wallpaper gluing machine (1) of the present invention, the length M is set to 10 cm. If the length M is 10 cm, the processing MTP7 is executed, and if the length M is 10 cm or less, the processing MTP5 is executed. Run.

In the processing MTP 5, the calculation unit (33) determines whether or not the “execution gluing length” L has reached the “set gluing length” J, and if L = J, the processing MTP 6 is executed.

In the processing MTP6, the calculation unit (33) stops the motor (24) and finishes the gluing execution.

In the processing MTP 7, the calculation unit (33) reads the number of pixels from the wallpaper end portion H of the image data to the scale line (54d), and detects the deviation from the “wallpaper end portion origin position”.
For example, if 415 pixels were present
As 0.04 mm × 415 = 16.6 mm, it is stored in the storage unit (35) as D (1) = 16.6 mm of the array D (n).
Absolute deviation value Z = | D (1) -D (0) |
Stored in the storage unit (35) with a deviation Z = 0.04 mm,
After initializing the s of the second counter with s = 0, the process proceeds to the processing MTP8.

In the processing MTP8, it is determined whether or not the deviation Z is within a predetermined range, and the deviation Z is determined.
If the deviation Z is within a predetermined range, the processing MTP3 is executed, and the process is executed.
If the deviation Z is outside the predetermined range, the processing MTP 6 is executed.
In the automatic wallpaper gluing machine (1) of the present invention, if the deviation Z is 1.0 mm or less, it is determined to be within a predetermined range. Therefore, when the deviation Z = 0.04 mm, the processing MTP3 is executed.

Then, the wallpaper A is further conveyed by 10 cm, and when the processing MTP4 determines that M = 10 cm and the processing MTP7 is executed again, the number of G (pixels) from the wallpaper end H to the scale line (54d) is read. For example, if there are 496 pixels,
As 0.04 mm × 496 = 15.8 mm, it is stored in the storage unit (35) as D (2) = 15.8 mm of the array D (n), and the absolute value of deviation Z = | D (2) − D (0). ) | By the formula
Stored in the storage unit (35) with a deviation Z = 1.20 mm,
After initializing the s of the second counter as s = 0, the process proceeds to the processing MTP8.
The processing MTP 6 is executed when the deviation Z is 1.0 mm or more and exceeds a predetermined range.
As described above, the automatic wallpaper glue machine (1) of the present invention obtains the deviation Z of the wallpaper end portion H of the wallpaper A from the "wallpaper end origin position" for each predetermined length M. The predetermined length M can be changed.

In the automatic wallpaper gluing machine (1) of the present invention, when the wallpaper end portion H is twisted, the length M corresponding to the second counter s is shortened, and the arrangement D (n) is finely chopped. Have and
For example, the processing MTP7 is executed every time the wallpaper A is conveyed by 2.5 cm, the number of pixels from the wallpaper end portion H of the image data to the scale line (54d) is read, and the array Z for averaging the deviation Z (arrangement Z). It has n), and the deviation Z for each 2.5 cm transport is stored in Z (1), Z (2), Z (3), Z (4), and the average deviation HZ = (Z (1)). It has a function of executing the processing MTP8 using the averaged HZ as + Z (2) + Z (3) + Z (4)) / 4.

The automatic wallpaper gluing machine (1) of the present invention has a setting to detect the wallpaper surface layer of the wallpaper A when the wallpaper edge H is twisted.
As shown in FIG. 6B, the wallpaper A has a structure in which the wallpaper surface layer L is superposed on the wallpaper lining layer M and a pattern is applied to the wallpaper surface layer L, and even in the case of the plain wallpaper A, the wallpaper The boundary between the backing layer and the wallpaper surface layer is linear, and the 17 scale lines such as the scale line (54a) and the boundary between the wallpaper backing layer and the wallpaper surface layer are parallel to each other.
When the setting to detect the wallpaper surface layer of the wallpaper A is made, the calculation unit (33) detects the boundary portion N between the wallpaper backing layer and the wallpaper surface layer, and the wallpaper backing layer is arranged in the array D (n) obtained by the processing MTP2 and the processing MTP7. And the distance from the boundary portion N of the wallpaper surface layer to the scale line (54d) is substituted.
By this method, even if the wallpaper end portion H is extremely twisted and damaged, the lateral displacement of the wallpaper A to be conveyed can be detected.

Further, in the automatic wallpaper gluing machine (1) of the present invention, when the maintenance person confirms the finished condition when adjusting the holding springs (not shown) at the left and right shaft ends of the measuring roller (8). It is equipped with an adjustment wallpaper J to be used for. FIG. 8A shows how to confirm the measuring accuracy using the adjustment wallpaper J. The adjustment wallpaper J has a width of 900 mm, a total length of 20 m, and marks K are provided at equal intervals in the longitudinal direction in the center.
In the automatic wallpaper gluing machine (1), since a photoelectric sensor (not shown) is used for the cross detection unit (32), the mark K is a hole. When it is mounted on the automatic wallpaper gluing machine (1) and transported, it is located directly under the cross detection unit (32), and at the mark K, the photoelectric sensor of the cross detection unit (32) (not shown). The configuration is such that the calculation unit (33) can detect that the light beam irradiated by the light beam is not reflected, the output is turned off, and the mark K, which is a hole, has passed.

FIG. 8B shows a cross signal (31) generated by the cross detection unit (32) and a scale signal (30) generated by the scale unit (18) when the adjustment wallpaper J is conveyed. Is shown.
The mark K is provided every 1.0 m, and the distance LS in FIG. 8B indicates that the adjustment wallpaper J has been conveyed by 1.0 m, and the automatic wallpaper gluing machine (1) adjusts the mark K. The diameters of the rotating plate (not shown) of the measuring unit (18) and the measuring roller (8) are determined so that one measuring signal (30) is generated every time the wallpaper J is conveyed by 2 mm. ing.
K in the graph of FIG. 8B indicates the number K of the scale signals (30) actually generated by the scale unit (18) when the adjustment wallpaper J is carried by the distance LS, and is adjusted. When the wallpaper J is transported without slipping and skewing with respect to the measuring roller (8), the cross detection unit (32) detects the mark K and then detects the next mark K (distance). During LS),
LS = 1000 mm ÷ 2.0 mm = 500 scale signals (30) are generated.
The automatic wallpaper gluing machine (1) of the present invention stores these 500 pieces in advance in the storage unit (35) as the theoretical measurement value Q when the adjustment wallpaper J is conveyed.
When the adjustment wallpaper J is actually transported, the measuring unit (18) is generated while the cross detection unit (32) detects the mark K and then detects the next mark K (during the distance LS). The number of the measured signal (30) counted by the calculation unit (33) is defined as the measured measured value K, and the theoretical measured value Q and the measured measured value K are compared. As a cause such as wear of the measuring roller (8),
The scale correction factor H is determined by the formula H = (Q−K) ÷ Q.
When the maintenance person uses this measuring roller (8) without replacing it with a new measuring roller (8), the display operation unit (34) to the calculation unit (33) of the automatic wallpaper gluing machine (1) ) Set the scale correction. When the scale correction is set, the calculation unit (33) calculates by the counter t ← t + 1 for counting the scale signal (30) and the formula L = t × P from the next time when the gluing is executed. The scale correction is performed by stopping the motor (24) at the position where the wallpaper A is conveyed to the length obtained by multiplying the “execution glue length” by the scale correction factor H.
By doing so, even if the measuring roller (8) is worn, there is no error in the “execution glue length”.

In the automatic wallpaper gluing machine (1) of the present invention, each value of the array D (n) stored in the processing MTP7 of the flowchart of FIG. 7, the length of the conveyed wallpaper, the length by the cross signal, and the scale signal ( Since the lengths of 30) are associated with each other and displayed in a graph on the display operation unit (34), the maintenance staff can use the left and right shaft ends of the measuring roller (8) of the automatic wallpaper gluing machine (1). You can easily check the finish when adjusting the presser spring (not shown). The automatic wallpaper gluing machine (1) of the present invention has a function of assisting the adjustment work of the maintenance person.

Further, as a means for detecting the edge of the wallpaper, a photodiode array having a lateral length of about 10 cm is provided upward on the entrance stay (17) of the slitter (6), and the upper side near the center of the photodiode array is the wallpaper of wallpaper A. Arranged so that the end H passes through, the light amount difference between the photodiode in the part where the light is blocked by the wallpaper A and the photodiode in the part where the light is incident without the wallpaper A is converted into a voltage difference and the wallpaper end. There is also a method of detecting the position of the portion H. In this case, if the conveyed wallpaper A sways in the vertical direction and a gap is created between the wallpaper A and the photodiode array, the voltage difference becomes ambiguous, so that the position of the wallpaper end H is accurately detected. This is a method that makes it difficult to detect the boundary portion N between the wallpaper lining layer and the wallpaper surface layer.
Further, as a wallpaper edge detecting means, a pair of upper and lower area sensors for light-emitting light are provided on the entrance stay (17) and the backside stay (16) of the slitter (6), and the vicinity of the center of the area sensor is provided on the wallpaper A. Arranged so that the wallpaper end H passes through, and the position of the wallpaper end H is detected by converting the difference in the amount of light between the portion where the light is blocked by the wallpaper A and the portion where the light is transmitted without the wallpaper A into a voltage difference. There is also a method. In this case, since the area sensor is expensive, the manufacturing cost of the automatic wallpaper gluing machine (1) is high, and the boundary portion N between the wallpaper lining layer and the wallpaper surface layer cannot be detected.

In the automatic wallpaper gluing machine (1) of the present invention, the mark K provided in the adjustment wallpaper J is used as a hole, but when a color sensor is used for the cross detection unit (32), the mark K is not a hole. As a color mark, the distance between the red mark and the red mark is 2.0 m, the distance between the black mark and the black mark is 3.0 m, the distance between the yellow mark and the yellow mark is 4.0 m, and so on. May be changed.
