  In addition, in the automatic wallpaper gluing machine (1) of the present invention, the lens (not shown) of the camera module (51) is attached 57.5 mm upward from the slitter entrance stay (17) of the slitter (6). Therefore, one pixel of the image data received by the calculation unit (33) corresponds to a distance of 0.04 mm in the horizontal direction (width direction) of the slitter entrance stay (17).

The mounting method of the camera module (51) to the slitter (6) will be described using FIGS. 4 and 5. FIG. In the slitter (6), an upper blade (28) and a lower blade (29) are conventionally attached to a blade block (38) on a blade drive shaft (not shown). The wallpaper A which contacts the blade guide (39) and is tensioned properly is cut by the upper blade (28) and the lower blade (29), and the left and right side edges I are the inner wall surface of the blade block (38) The wallpaper A is transported to the gluing roller (12) by the delivery roller (9) and the measuring roller (8).
Also, conventionally, the upper blade (28) and the lower blade (29) together with the cutter block (38) are slitters (6) to adjust the width of the side edge I to be cut and to determine the width of the wallpaper A. The adjustment can be made by moving in the width direction of the blade. Loosen the blade position adjustment screw (41) and loosen the blade position fixing plate (40) to adjust the blade position provided on the slitter back stay (16). It is movable along the hole (42).

  In the automatic wallpaper gluing machine (1) of the present invention, the camera module mounting plate (52) is sandwiched and held between the blade position fixing plate (40) and the slitter back stay (16), the side to be cut off Even when the upper blade (28) and the lower blade (29) are moved inward in order to widen the edge I, only the camera module (51) is moved outward to It can be placed directly above.

  In addition, the camera module (51) is connected to the control board (37) inside the control device (5) by a camera module signal line (not shown), and the operation unit (33) is a camera module (51) Is configured to be able to receive the image data taken by the camera constantly.

Also, as shown in FIG. 6, in the slitter entrance stay (17) of the slitter (6),
A scale seal (53) provided with 17 scale lines such as the scale lines (54a) is attached, and the 17 scale lines such as the scale lines (54a) are the wallpaper edge H of the transported wallpaper A. And the front side of the upper blade (28) and the lower blade (29).
In addition, 17 scale lines such as the scale line (54a) are provided at intervals of 10.0 mm, and 250 pixels exist between 10.0 mm in the image data captured by the camera module (51). As described above, the mounting height in the vertical direction of the camera module (51) and the longitudinal direction are determined by the shape and dimensions of the camera module mounting plate (52).
In the lateral direction (the width direction of the wallpaper A), the wallpaper edge H before the side edge I is cut by the upper blade (28) and the lower blade (29), and a scale such as a 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 a line, and the position of the image captured by the camera module (51) Is configured so that alignment can be performed while looking at the display operation unit (134), and can be adapted to various wallpaper A having different widths.

A sequence in which the computing unit (33) of the automatic wallpaper pasting machine (1) of the present invention detects skew of the wallpaper A will be described using the flowchart of FIG.
In the process MTP1, "set glued length" and "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) The pasting length is stored in the variable J.
When the start switch (not shown) is pressed, the operation unit (33) initializes the parameters necessary to execute the process, and the parameters t, L, and s which are parameters used in the process MTP 4 , Parameter M is also initialized.

In the process MTP2, the computing unit (33) detects the position of the wallpaper end H before activating the motor (24).
The range indicated by the one-dot chain line in FIG. 6 is the range of the image captured by the camera module (51),
The calculation unit (33) jumps the scale line (54e) from the end H of the wallpaper to obtain the distance to the scale line (54d).
The method is, for example, 17.0 mm in FIG. 6 from the wallpaper end H to the scale line (54 d), there are 425 pixels in the image data from the wallpaper end H to the scale line (54 d) . (As described above, this is because the camera module (51) is disposed so that one pixel is 0.04 mm).
The arithmetic unit (33) reads the number of pixels of the image data,
Assuming that 0.04 mm × 425 = 17.0 mm,
In the array D (n) for storing the distance between the wallpaper end H and the scale line (54d),
It stores in the storage unit (35) as D (0) = 17.0 mm.
Let D (0) = 17.0 mm, which is the distance between the wallpaper edge H before the start of transportation and the scale line (54 d), be the “wallpaper edge origin position”.
Subsequently, the calculation unit (33) issues a command to the motor control unit (36) to start the motor (24), and the conveyance of the wallpaper A is started.

In the process MTP3, the calculation unit (33) counts the measurement signal (30) generated by the measurement unit (18) and calculates the "performed gluing length" of the transported wallpaper A.
As the first counter
The parameter t is added as t ← t + 1 each time one measurement signal (30) is counted,
The “performing gluing length” L is determined by L = t × P, (P is based on the moving distance of the wallpaper A (the diameter of the measuring roller (8) when one measuring signal (30) is counted) Constant)).
In addition, as a second counter for determining the timing of detecting the deviation Z,
The parameter s is added as s ← s + 1, and the measurement signal (30) is incremented by one each time to obtain a length M corresponding to the second counter s as M = s × P.

In the process MTP4, the computing unit (33) determines whether 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, and if the length M is 10 cm, the treatment MTP7 is executed, and if the length M is 10 cm or less, the treatment MTP5 Run.

  In the process MTP5, the computing unit (33) determines whether the "performing gluing length" L has reached the "set gluing length" J, and when L = J, the process MTP6 is executed.

  In the process MTP6, the calculation unit (33) stops the motor (24) to finish the glue application.

In the process MTP7, the computing unit (33) reads the number of pixels from the wallpaper edge H of the image data to the scale line (54d), and detects a deviation from the "wallpaper edge origin position".
For example, if there are 415 pixels,
Store in the storage unit (35) as D (1) = 16.6 mm of the array D (n) as 0.04 mm × 415 = 16.6 mm,
According to the equation of displacement absolute value Z = | D (1) −D (0) |
Store in the storage unit (35) as Z = 0.04 mm,
After initializing s of the second counter as s = 0, the process proceeds to processing MTP8.

In the process MTP8, it is determined whether the deviation Z is within a predetermined range,
If the deviation Z is within the predetermined range, the process MTP3 is executed,
If the deviation Z is outside the predetermined range, the process MTP6 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 the predetermined range. Therefore, when the deviation Z = 0.04 mm, the processing MTP3 is executed.

Then, the wallpaper A is further transported by 10 cm, and it is determined that M = 10 cm in the processing MTP4. When the processing MTP7 is executed again, the number of G (pixels) from the wallpaper edge H to the scale (54 d) is read For example, if there are 496 pixels,
It stores in the storage unit (35) as D (2) = 15.8 mm of the array D (n) as 0.04 mm × 496 = 15.8 mm, and the deviation absolute value Z = | D (2) −D (0 According to the formula of ||
Store in the storage unit (35) as the displacement Z = 1.20 mm,
After initializing s of the second counter as s = 0, proceed to processing MTP8,
The processing MTP 6 is executed when the deviation Z is 1.0 mm or more and exceeds the predetermined range.
As described above, the automatic wallpaper pasting machine (1) of the present invention is for finding the deviation Z of the wallpaper end H of the wallpaper A from the “wallpaper end origin position” for every predetermined length M, The predetermined length M can be changed.

In the automatic wallpaper gluing machine (1) of the present invention, when the wallpaper edge H is twisted, the length M corresponding to the second counter s is shortened and the setting for finely cutting the array D (n) is performed. Have
For example, every time the wallpaper A is transported 2.5 cm, the processing MTP 7 is executed to read the number of pixels from the wallpaper edge H of the image data to the scale line (54 d), and array Z for averaging the offset Z ( n), store the displacement Z every 2.5 cm transported in Z (1), Z (2), Z (3), Z (4), and average displacement HZ = (Z (1) It has a function of executing the processing MTP 8 using the averaged HZ as + Z (2) + Z (3) + Z (4)) ÷ 4.

In the automatic wallpaper pasting machine (1) of the present invention, the wallpaper surface layer of the wallpaper A is set to be detected when the wallpaper end H is twisted.
As shown in FIG. 6 (b), the wallpaper A has a structure in which the wallpaper surface L is superimposed on the wallpaper backing layer M, and a pattern is applied to the wallpaper surface L. Even in the case of the plain wallpaper A, the wallpaper A The boundary between the backing layer and the wallpaper surface is linear, and the 17 graduations such as the scale (54a) are parallel to the boundary between the wallpaper backing layer and the wallpaper surface.
When setting is made to detect the wallpaper surface layer of the wallpaper A, the operation unit (33) detects the boundary N between the wallpaper backing layer and the wallpaper surface layer, and sets the wallpaper backing layer to 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 to the scale line (54d).
By this method, it is possible to detect the lateral displacement of the transported wallpaper A even when the wallpaper edge H is extremely distorted.

Further, in the automatic wallpaper gluing machine (1) of the present invention, the maintenance person in charge checks the finish when adjusting the pressing springs (not shown) of the left and right shaft ends of the measuring roller (8). It is equipped with wallpaper J for adjustment. FIG. 8A shows how the measurement accuracy is checked using the adjustment wallpaper J. As shown in FIG. The adjustment wallpaper J has a width of 900 mm and a total length of 20 m, and marks K are provided at equal intervals in the longitudinal direction at the center.
In the automatic wallpaper gluing machine (1), since the photoelectric sensor (not shown) is used for the cross detection unit (32), the mark K is a punching hole. When mounted on the automatic wallpaper gluing machine (1) and transported, the photoelectric sensor (not shown) of the cross detection unit (32) is located immediately below the cross detection unit (32) and where the mark K is located. The light beam irradiated is not reflected, the output is turned off, and the calculation unit (33) can detect that 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 measurement signal (30) generated by the measurement 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. 8 (b) indicates that the adjustment wallpaper J has been transported by 1.0 m, and in the automatic wallpaper pasting machine (1), the adjustment is performed Determine the diameters of the rotary plate (not shown) and the measuring roller (8) of the measuring section (18) so that one measurement signal (30) is generated each time the wallpaper J is transported by 2 mm. ing.
K in the graph of FIG. 8B indicates the number K of the measurement signals (30) actually generated by the measurement unit (18) when the adjustment wallpaper J is transported by the distance LS, and adjustment is performed. Between the cross detection unit (32) detecting the mark K and detecting the next mark K when the wallpaper J is conveyed without slippage and skewing with respect to the measuring roller (8) (distance During LS))
LS = 1000 mm ÷ 2.0 mm = 500 measurement signals (30) are generated.
The automatic wallpaper pasting machine (1) according to the present invention previously stores 500 pieces of these 500 values in the storage unit (35) as the measurement theoretical value Q when the adjustment wallpaper J is transported,
When the wallpaper J for adjustment is actually conveyed, the measuring section (18) generates while the cross detection unit (32) detects the mark K and then detects the next mark K (during the distance LS) Assuming that the number of measured scaling signals (30) counted by the calculation unit (33) is K measured measurement values and comparing the theoretical measurement value Q with the actual measurement value K, and a difference occurs, As the cause of wear of the measuring roller (8)
The scaling correction factor H is determined by the formula H = (Q−K) ÷ Q.
The maintenance person in charge uses the display / operation unit (34) of the automatic wallpaper gluing machine (1) from the operation unit (33) when using the measurement roller (8) without replacing it with a new measurement roller (8). Set the calibration correction to). When the size measurement correction is set, the calculation unit (33) calculates from the next time the pasting is performed, a counter ttt + 1 for counting the size measurement signal (30), and the equation L = t × P. The measurement measurement correction is performed by stopping the motor (24) at a position where the wallpaper A has been transported to a length obtained by multiplying the “performed gluing length” by the measurement correction factor H.
By doing this, even when the measuring roller (8) is worn, there is no error in the "performed gluing length".

  In the automatic wallpaper gluing machine (1) of the present invention, each value of the array D (n) stored in the process MTP7 of the flowchart of FIG. 7, the length of the transported wallpaper, the length by the cross signal and the measurement signal ( 30) The lengths of the left and right axes of the measurement roller (8) of the automatic wallpaper gluing machine (1) are maintained by correlating the lengths of the lengths 30 and displaying them on the display operation unit (34). It is possible to easily check the finish when adjusting the pressure spring (not shown) and the like. The automatic wallpaper gluing machine (1) of the present invention has a function of assisting the maintenance work of the maintenance person.

Also, as a wallpaper edge detection means, a photodiode array with 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 The edge H is disposed so as to pass through, and the light amount difference between the photodiode where the light is blocked by the wallpaper A and the photodiode where the light is incident without the wallpaper A is converted to a voltage difference and the wallpaper edge There is also a method of detecting the position of part H. In this case, when the wallpaper A being conveyed swings in the vertical direction and a gap is generated between the wallpaper A and the photodiode array, the voltage difference becomes unclear, so the position of the wallpaper edge H is accurately detected. It is a method that is difficult to do, and is a method that can not detect the boundary N between the wallpaper backing layer and the wallpaper surface layer.
In addition, as the wallpaper edge detection means, a light emitting / receiving pair of upper and lower area sensors etc. is provided on the entrance stay (17) and slitter back stay (16) of the slitter (6). Arranged so that the wallpaper edge H passes through, and detects the position of the wallpaper edge H by converting the light amount difference between the portion where light is blocked by the wallpaper A and the portion where light is transmitted without the wallpaper A into a voltage difference. There is also a way. In this case, since the area sensor is expensive, it is a method in which the manufacturing cost of the automatic wallpaper gluing machine (1) is expensive, and a method in which the boundary N between the wallpaper backing layer and the wallpaper surface can not be detected.

In the automatic wallpaper gluing machine (1) of the present invention, the mark K provided on the adjustment wallpaper J is a punched hole, but when a color sensor is used for the cross detection unit (32), the mark K is not a punched hole Space between colors of mark K, such as color mark, 2.0 m between red mark and red mark, 3.0 m between black mark and black mark, 4.0 m between yellow mark and yellow mark, etc. You may change the
