Description

The present invention relates to a composite printing device, and more particularly to a composite printing device that performs printing on a cloth by a plateless printing unit and printing on a fabric by a plated printing unit in parallel.

Conventionally, there are plate printing and non-plate printing as a method of printing on fabric. Plated printing, also called screen printing, is a printing method using a plate having a screen. A through hole (opening) corresponding to a predetermined pattern is formed on the screen, and ink is supplied onto the screen, and the squeegee moves (rubs) on the plate while pressing the ink, so that the ink penetrates. A predetermined pattern is printed on the fabric through the holes. Plates are created for each color of ink used.

Plated printing is suitable for printing a single-color background of a pattern because it is possible to print a large area of fabric in the same color according to the size of the through hole of the plate by moving the squeegee once. High-speed printing is possible. On the other hand, since it is necessary to create a plate for each color of ink, there is a problem that it takes time and cost and it is difficult to express a pattern in multiple colors.

Plateless printing refers to a printing method in which ink is directly sprayed onto a fabric without using a plate, and for example, there is printing using an inkjet head. The inkjet head includes an ink tank that stores inks of each color and a nozzle that is connected to the ink tank, and ejects ink from the nozzles to print on the fabric. In non-plate printing, for example, inks of colors called process colors such as cyan (blue), magenta (red), yellow (yellow), and black (black) are overprinted with shading, so plate printing is performed. Compared to the above, it is possible to express many colors, and it is possible to express fine and complicated patterns. However, since ink is sprayed onto the fabric for printing, only a small area can be printed at one time as compared with plate printing, and there is a problem that printing takes time.

In order to solve the above problem, Patent Document 1 proposes a printing apparatus in which plate printing and plateless printing are combined. The printing apparatus of Patent Document 1 includes a transport section for continuously transporting a long cloth by a transport belt, a plate printing section, and a plateless printing section, and the transport belt is provided with a position adjustment mark. ing. The fabric is conveyed by the transport belt and printed on the fabric by the plated printing unit, and further the fabric is conveyed and printed on the fabric by the plateless printing unit. As a result, a pattern printed by plate printing and a pattern printed by non-plate printing are printed on the fabric. At this time, a pattern such as a background having a small number of colors and a large area per color is printed by the plate printing section, and a fine pattern having a large number of colors is printed by the non-plate printing section, so that the number of printed patterns is large. In addition to enabling color expression, the printing speed is faster than when only plateless printing is performed, and the drawbacks of plated printing and plateless printing can be compensated for.

In order to print a design by plate printing and non-plate printing, it is necessary to match the printing position of the design by plate printing with the printing position of the design by non-plate printing. In the printing apparatus of Cited Document 1, a plurality of position adjustment marks are provided on the transport belt. In the plate-printing section where printing is performed first, a mark having the same shape as the position adjustment mark provided on the transport belt is provided on the plate, and the position adjustment mark and the plate mark provided on the transport belt are provided. The pattern is printed continuously by aligning the pattern so that it matches.
The plateless printing unit is equipped with a position confirmation sensor that detects the position of the position adjustment mark and a position adjustment mechanism that adjusts the position of the inkjet nozzle based on the position of the mark, according to the position of the position adjustment mark. Print the design.

Japanese Patent No. 3218274

However, in the case of the printing apparatus described in Cited Document 1, it is not clear how the position adjusting mark of the transport belt and the plate mark are aligned in the plated printing unit to be printed first. For example, when the transfer belt is controlled by a drive motor such as a servomotor to align the position adjustment mark provided on the fabric or the transfer belt with the plate, the core deviation of the drive roll on which the transfer belt is hung is performed. In addition, a transport belt made of an elastic body such as urethane rubber may expand and contract slightly during transport, resulting in a transport error of about ± 0.2 mm.

As described above, in the plate printing section, the accuracy of the alignment between the position adjustment mark and the plate is coarse. Therefore, as shown in FIG. 14, the printed portion of the pattern by plate printing A1-1 (FIG. 14 (A)). ), When the design is printed by plate printing, the print part A1-2 of the later design overlaps with the print part A1-1 of the previous design (FIG. 14 (B)), and the subsequent printing. There may be a gap between the portion A1-3 and the printed portion A1-2 (FIG. 14 (C)). After the plate printing is finished, the plateless printing is further performed according to the position adjustment mark A3, but since the printed part A1-2 of the pattern by the plate printing is deviated from the position adjustment mark A3, the plate is printed. There is a problem that the position of the printed portion A2 of the symbol printed by non-plate printing is misaligned with respect to the printed portion A1-2 of the symbol printed by printing (FIG. 14 (D)), and the symbol cannot be printed accurately and the printing accuracy is poor.

The present invention has been made in view of the above problems, and in a composite printing apparatus provided with a plated printing unit and a plateless printing unit, a printed portion by plateless printing and a printed portion by plated printing are accurately printed. The challenge is to make it possible.

The composite printing apparatus according to the present invention includes a transport belt that supports and transports the fabric to be printed on the upper surface, and a measuring device that is provided on the transport path of the fabric by the transport belt and measures the linear movement distance of the transport belt. A plateless printing unit having a plateless printing unit, a plated printing unit provided at a position downstream of the plateless printing unit on the transport path of the fabric, and a straight line corresponding to the printing pitch of the plateless printing unit by the measuring device. Each time the movement distance is measured, the control unit is provided to stop the movement of the transfer belt and intermittently operate the transfer belt. The plateless printing unit prints marks at intervals corresponding to the printing pitch of the plated printing unit, and the plated printing unit prints the fabric printed portion by the plateless printing unit when it is conveyed. A plate position adjusting mechanism for moving the position of the plate according to the amount of displacement of the plate with respect to the mark is provided.

First, the non-plate printing unit prints a pattern (hereinafter, also referred to as "non-plate printing"). At this time, the plateless printing unit prints the mark at each distance corresponding to the printing pitch of the plated printing unit. In the non-plate printing section, the transport belt moves accurately by a distance corresponding to the printing pitch of the non-plate printing section by measuring the linear movement distance of the transport belt with a measuring device. The printed part and the next printed part are not overlapped or there is no gap, and the print is performed exactly at the distance corresponding to the print pitch, and the mark is printed at the distance corresponding to the print pitch of the plated printing part. Is printed accurately. Next, the fabric is conveyed to the plate printing section by the transport belt, and the pattern is printed by the plate printing section (hereinafter, also referred to as "plate printing"). Since the position of the plate is moved according to the amount of misalignment of the plate with respect to the plate to align the mark and the plate, the printed portion of the printed portion of the plate does not misalign with the printed portion of the non-plate printed portion. Therefore, the printed portion by plateless printing and the printed portion by plated printing can be printed with high accuracy.

In a preferred embodiment, the mark is printed on the surface of the fabric or the transport belt.

According to one embodiment, the plate position adjusting mechanism moves a plate by a sensor that detects a plate misalignment amount with respect to the mark and a plate that moves the plate by a distance corresponding to the plate misalignment amount detected by the sensor. Including the mechanism.

According to one embodiment, the sensor is a two-dimensional CCD camera provided integrally with the plate of the plate printing unit.

The plate moving mechanism preferably moves the plate in the X direction along the progressive feeding direction of the fabric and in the Y direction orthogonal to the X direction.

In one embodiment, the measuring device uses a clamp mechanism portion that clamps the transport belt at an initial position and follows the transport belt, and a distance that the clamp mechanism portion follows the transport belt as the linear movement distance. The measurement unit to be measured, a return operation mechanism unit for returning the clamp mechanism to the initial position, and a control unit for controlling each of the clamp mechanism unit and the return operation mechanism unit are included, and the control unit includes the control unit. Every time the measuring unit measures a distance corresponding to the printing pitch, the clamp operation by the clamp mechanism unit is released, and the return operation mechanism unit returns the clamp mechanism unit to the initial position.

When the clamp mechanism unit clamps the transport belt at the initial position and moves linearly following the operation of the transport belt, the measuring unit measures the moving distance of the clamp mechanism unit. When the clamp mechanism moves a distance corresponding to the printing pitch, the control stops the operation of the conveyor belt, releases the clamp operation by the clamp mechanism, and returns the clamp mechanism to the initial position by the return operation mechanism. ..

The print pitch of the plated printing section is preferably an integral multiple of the printing pitch of the non-plate printing section.

According to the present invention, it is possible to accurately print a printed portion by plateless printing and a printed portion by plated printing.

Slide members 79a and 79a are provided on the lower surface of the X table 79 at positions facing the guide rails 78 and 78, and the slide members 79a and 79a are fitted to the guide rails 78 and 78 so that they can slide in the X direction. It has become.

A nut member (not shown) through which the screw 81 penetrates and is screwed is provided on the lower surface of the X table 79. A servomotor 82 that rotates the screw 81 is attached to one end of the screw 81, and the other end of the screw 81 is supported by a support member (not shown) provided on the X table 79 via a ball bearing. .. By rotating the screw 81 with the servomotor 82, the X table 79 moves in the X direction. The X table 79 is provided with a connecting portion 84 that is connected to the frame 63 of the plate 60. The connecting portion 84 of the X table 79 is provided with a cylindrical protrusion 85 facing upward, and the protrusion 85 is rotatably fitted into the hole 86 provided in the frame 63, whereby the X table 79 The frame 63 is connected to the frame 63.

The one-way table 71 provided on the other end side of the frame 63 can move in the X direction, which is the forward feed direction of the fabric C. The one-way table 71 is such that the X table 79 is slidably mounted on the base, and the configuration in which the X table 79 slides on the base is such that the X table 79 of the two-way table 70 is a Y table. Since it is the same as the configuration of sliding on 74, the description thereof will be omitted. As shown in FIG. 7B, the connecting portion 84 of the X table 79 is provided with a cylindrical protrusion 88 facing upward. The frame 63 is provided with a groove 87 extending in the width direction of the fabric C and having an open end. The protrusion 88 is fitted along the groove 87 so as to be freely movable and rotatable, so that the frame 63 is connected to the X table 79 of the one-way table 71.

In order to move the frame 63 of the plate 60 in the X direction, the servomotor 82 provided on the two-way table 70 and the servomotor 82 provided on the one-way table 71 are driven in synchronization with each other. As a result, the connecting portion 84 of the two-way table 70 and the connecting portion 84 of the one-way table 71 apply a pressing force in the X direction to the frame 63, and the frame 63 moves in the X direction.
To move the frame 63 of the plate 60 in the Y direction, the servomotor 76 of the two-way table 70 is driven. As a result, the connecting portion 84 of the two-way table 70 applies a pressing force in the Y direction to the frame 63, and the frame 63 moves in the Y direction. At this time, the protrusion 88 of the connecting portion 84 of the one-way table 71 moves along the groove 87 of the frame 63.

When only the servomotor 82 of the one-way table 71 is driven, the frame 63 rotates about the protrusion 85 of the connecting portion 84 of the two-way table 70. The frame 63 may be rotated by driving only the servomotor 82 of the two-way table 70.
The configuration of the plate moving mechanism 69 is not limited to the above embodiment, and any configuration may be used as long as the plate 60 can be moved and rotated.

The sensor 68 is provided integrally with the plate 60 on the outside of the plate 60 by a support member 89 extending from the connecting portion 84 of the bidirectional table 70. In this embodiment, the sensor 68 is a two-dimensional CCD camera. As shown in FIGS. 8 (A) and 8 (B), when the printed portion E1 of the fabric C by the non-plate printing unit 3 is conveyed to the plate printing unit 4, the range S of the image acquired by the camera. The image of the mark M printed on the cloth C by the non-plate printing unit 3 is inserted in. The position of the plate 60 at the time of printing is determined with reference to the mark M, and the predetermined position S1 defined within the range S of the image (in the embodiment of FIGS. 8 (A) and 8 (B), the range S of the image). The plate printing is performed at the position of the plate 60 when the position S2 of the image of the mark M coincides with the central portion of the mark M. Therefore, if the mark M in the range S of the camera image is deviated from the predetermined position S1, the position of the plate 60 is deviated from the mark M, and the misalignment amount S3 of the plate 60 is the predetermined position of the plate 60. It is acquired by the amount that the mark M deviates from S1.

Specifically, the control unit 5 stores a reference image in which the mark M1 is arranged in advance at a predetermined position S1. When the printing portion E1 of the fabric C by the non-plate printing unit 3 is conveyed to the plate printing unit 4, the control unit 5 obtains an input image by the sensor 68. This input image is compared with the reference image, and the amount of misalignment S3 between the mark M1 of the reference image and the mark M of the input image is obtained. The misalignment amount S3 includes a case where the position is deviated on the XY plane as shown in FIG. 8 (A) (displacement amount S3-1) and a mark M as shown in FIG. 8 (B). Includes one or both of cases where the inclination (angle) of is deviated from the reference mark M1 of the reference image (displacement amount S3-2). The control unit 5 obtains a misalignment amount S3 including one or both of the misalignment amount S3-1 and the misalignment amount S3-2, controls the servomotors 76 and 82 according to the misalignment amount S3, and controls the two-way table 70. , The one-way table 71 is operated to move, rotate, or both of the plate 60.

The sensor 68 does not necessarily have to be provided at the connecting portion 84 of the two-way table 70, and may be provided at an arbitrary position as long as the misalignment amount S3 between the mark M and the plate 60 can be detected. .. The shape of the mark M is a right-angled isosceles triangle in the embodiment shown in FIG. 8, but may be a polygon such as a quadrangle or a circle, as long as the sensor 68 can recognize the shape. It may be in the shape of.
Further, the sensor 68 is not necessarily a two-dimensional CCD camera, and may be any sensor as long as it can detect the amount of misalignment S3 between the mark M and the plate 60.

(Operation of plateless printing unit 3 and plated printing unit 4)
The control unit 5 intermittently operates the transport belt 22 in the plateless printing unit 3 to perform plateless printing. Specifically, the control unit 5 stops the movement of the transport belt 22 each time the measuring device 33 measures the linear movement distance corresponding to the printing pitch L1 of the non-plate printing unit 3, and makes the head unit 31 the width of the fabric C. Plateless printing is performed by scanning in the direction. At this time, the mark M is printed on the surface of the fabric C by the plateless printing unit 3 at each distance corresponding to the printing pitch L2 of the plated printing unit 4. In the example shown in FIG. 9A, the printing pitch L2 of the plated printing unit 4 is five times the printing pitch L1 of the plateless printing unit 3, and the mark M is printed every time the plateless printing is performed five times. ..

The position where the mark M is printed is the area where the pattern at the end of the fabric C in the width direction is not printed, and the sensor 68 of the plate position adjusting mechanism 62 when the fabric C is conveyed to the plate printing unit 4. It is a position where the mark M can be imaged. The position for printing the mark M may be any position on the fabric C as long as the sensor 68 can image the mark M. Further, the mark M may be printed on the transport belt 22.

At the time of plateless printing, the moving distance of the transfer belt 22 is measured by the measuring device 33 and the transfer belt 22 is sequentially fed. It is printed accurately for each L1 and the mark M is accurately printed for each printing pitch L2 of the plated printing unit 4. That is, the mark M is accurately printed at a position corresponding to the printed portion E1 without being displaced with respect to the printed portion E1 of the non-plate printing unit 3.

In the plate printing unit 4, printing is performed by aligning the position of the plate 60 with the mark M printed by the plateless printing unit 3. When the printed portion E1 of the fabric C by the non-plate printing unit 3 is conveyed to the plated printing unit 4, the image of the mark M enters the range S of the image of the sensor 68. When the fixed position S1 at the plate 60 and the position S2 of the mark M do not match and a misalignment occurs, the control unit 5 moves the plate 60 by the misalignment amount S3 by the plate moving mechanism 69, and the sensor 68. Align the plate 60 and the mark M so that the amount of deviation between the plate 60 and the mark M becomes zero on the image acquired in. After that, plate printing is performed. As a result, as shown in FIG. 9B, the printing portion E1 by the plateless printing unit 3 can be printed without shifting the position of the printing portion E2 by the plated printing unit 4 with respect to the printing portion E1 by the plateless printing unit 3.

Further, in FIGS. 10B to 10D, in order to explain the printing order, the printing portions E1, E2, and E3 are laminated according to the printing order, but they are actually shown. The printed portions E1, E2, and E3 are printed on the cloth C, and the printed portions E1, E2, and E3 are not overlapped with each other. In the embodiment shown in FIG. 10, the plated printing unit 4 is arranged downstream from the plateless printing unit 3 by a distance three times the printing pitch L1 of the plateless printing unit 3, and is arranged on the downstream side of the plateless printing unit 4.

Here, the non-plate printing unit 3 is stopped, and the printing portion E2 is printed by the first plated printing unit 4.

When printing by the first plated printing unit 4 is completed, the fabric C is sequentially fed by the printing pitch L1 of the plateless printing unit 3 for each intermittent operation of the transport belt 22, and plateless printing is sequentially performed. As shown in FIG. 10C, when the plateless printing is repeated four times, the printing portion E1 by the plateless printing unit 3 is conveyed to the printing position by the first plated printing unit 4. Here, the non-plate printing unit 3 is stopped, and the printing portion E2 is printed by the first plated printing unit 4 in succession to the previously printed printing portion E2 by the first plated printing unit 4. ..

The printing portion E2 by the plate printing unit 4 can be printed without being displaced. Therefore, the printing portion E1 by the plateless printing unit 3 and the printing portion E2 by the plated printing unit 4 can be printed with high accuracy.
