Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fully automatic printing device for color matching that can automatically carry out all color matching tests of printed patterns on fabrics.

(Conventional technology) Before dyeing mass-produced printed fabrics, it is necessary to perform color matching in order to dye the fabric to a similar hue to the sample color.

Traditionally, color matching work has mainly been done using a screen printing machine for testing, setting several sheets of a specified print pattern into the machine, and applying a specified color paste (dyeing paste) to each print pattern in the same place. A device that supplies and prints is used. When using a screen printing machine for testing, everything except the printing operation must be done manually.

(Section B to be solved) Conventional color matching work involves setting the test fabric in the test screen printing machine, removing the printed fabric from the machine after printing, and replacing the screen formwork when replacing the color glue.・
Most of the cleaning, cleaning of the squeegee, etc. is done manually, so when hundreds of sheets are to be color matched, the workers are forced to work extremely hard. Moreover, this type of work cannot be interrupted and requires overtime work.

In view of this situation, the present invention aims to provide a fully automatic printing device for color matching that solves the conventional problems and is capable of fully automatically processing this color matching work. .

(Means for Solving the Problems) The present invention provides a formwork support mechanism that is provided on a machine body and holds two formworks that can be horizontally rotated and stopped at fixed positions by 180 degrees, and a formwork support mechanism that a squeegee and a squeegee support mechanism that performs a printing operation by contacting the screen surface of the formwork at a position above one of the formworks, and a squeegee support mechanism that is intermittently fed at a required pitch directly below the formwork that is subjected to the printing operation by the squeegee. a belt conveyor for conveying the test cloth; a water shower and drying air injection means for washing and drying the formwork at a standby position of the formwork support mechanism; and a squeegee that is horizontally rotated by the squeegee support mechanism. a cleaning treatment means for cleaning and drying at a position evacuated from above the belt conveyor, and a color paste supplying means for supplying a large number of test color pastes supplied by the supply conveyor to the screen surface of the formwork to be subjected to printing operation. This is a fully automatic printing device for color matching that has a robot and an electric control mechanism that interlocks and operates these parts intermittently.

In the apparatus of the present invention, the formwork support frames in the formwork support mechanism support the formworks in a reversible manner at symmetrical positions from the center of rotation, and are provided with fixing means so that the screen surface is always maintained in a horizontal state. It is preferable to have an attached configuration. In addition, the formwork support frame in the formwork support mechanism is
It is preferable to configure the printing form so that it can be lifted up after printing is completed by a jack supported on the frame of the machine body via the support base.

In addition, the squeegee support mechanism is mounted on the frame of the machine at a position above the form support mechanism, and is connected via a post erected on a movable platform that can freely move back and forth in parallel to the belt conveyor that conveys the test fabric for the required distance. It is preferable that the squeegee be attached to a support body that can be moved in and out and up and down, and that the support part of the squeegee can be pivoted from a printing operation position to a washing position provided on the frame of the machine body.

The heald conveyor for transporting the test fabric according to the present invention has a fabric holding plate placed in front and behind the formwork in the flow direction of the test fabric at the printing position in the test fabric conveyance section, so that the test fabric is lifted when the formwork is lifted after the printing operation. It is preferable to provide a mechanism that can be pressed so that it does not lift up.

Further, wash water receiving trays are placed on the lower side of the formwork support frame at the standby side position of the formwork and on the machine frame above the rotating part of the formwork support frame, and drainage system piping is installed. It is preferable that the air is connected to the plate, and that a cleaning water injection mechanism and a drying air injection means are respectively arranged for the formwork to be cleaned and the squeegee to be cleaned.

(Function) The device of the present invention has a separately adjusted test color paste supply conveyor and a color paste supply robot that sucks up an appropriate amount of the test color paste and supplies it onto the formwork screen at the printing position, which are arranged adjacent to each other. used. The test cloth is attached by gluing or the like to a held conveyor belt that conveys the continuous cloth, and is fed intermittently at required intervals.

The formwork support frame of the formwork support mechanism first attaches to the formwork each time the test fabric is intermittently fed with a certain pinch and stops feeding the test fabric attached to the belt conveyor for conveying the test fabric. is lowered so that the screen surface of the test cloth is in close contact with the test cloth. In this state, the colored glue supply robot is activated, sucks in the required amount of adjusted and sent colored glue, and supplies it to a predetermined position on the screen surface of the formwork. The robot is designed so that the colored paste transfer part is cleaned after each feeding operation.)
.

When the colored glue supply operation is completed, the squeegee support mechanism is activated and moderate pressure is applied to the squeegee that was in standby at a position outside the colored glue supply position (lower or upper side in the flow direction on the conveyor belt). After that, the squeegee is moved to the screen effective working area of the formwork,
Color paste is printed (hereinafter referred to as printing) onto the test fabric through the screen mold surface. At this time, the printing operation is performed by applying a required pressing force to the squeegee, and then moving the squeegee by running a movable table and using a squeegee support attached to the movable table via an erected post. Note that, before this printing operation, a cloth presser plate is pressed onto the test cloth at positions before and after the printing position to prevent the test cloth from moving.

When the printing is completed, the squeegee raises the screen surface and releases it, and then the mold together with its mold support frame (the entire mold support mechanism) is raised by an appropriate amount to release the screen surface of the mold from the test fabric.

After that, the fixing force exerted by the cloth presser plate pressing the test cloth at the front and back positions of the printing position is released.

When such a printing operation is completed, the printed portion of the test cloth is advanced by one pitch. During this time, the squeegee support is rotated to the washing position on the upper part of the frame of the machine by the operation of the rotating device of the squeegee support mechanism, and at this position, the colored glue adhering to the squeegee is first washed off by jetted water, and then Moisture is removed and dried using compressed air (preferably hot air). Separately, the formwork after printing is moved by the formwork support frame of the formwork support mechanism being rotated and moved 180 degrees, the formwork that was in the standby position is moved to the print position, and the formwork that has been printed is moved to the print position. is switched to the standby position. The squeegee that has been cleaned is returned to the standby position (the position before the scraping operation) by inverting the squeegee support and moving the moving table backwards.

Thereafter, as described above, the mold, along with its mold support frame, is brought into contact with the test fabric by lowering the jack that was lifting the support base. At the same time, the cloth presser plate is also brought into a presser operation state to supply colored glue.

While this print preparation operation is in progress, the formwork moved to the standby position is sprayed with cleaning water to wash off the remaining colored paste. In addition, the formwork is cleaned and
After washing with water, compressed air (preferably hot air) is jetted to remove and dry the moisture adhering to the screen surface.

After cleaning, removing adhering moisture, and drying, the mold is returned to a predetermined orientation and fixed, and is kept on standby until the next printing operation. Thereafter, this operation is repeated to sequentially perform the required number of printing operations for the colored paste.

The printed part of the test cloth is fed intermittently, and a print number is added by a printing machine (or by the operator's hand) along the way, and then hot air is applied to remove moisture, and the dye is fixed by post-processing. It is sent out of the device in a state where no color transfer occurs until it is operated.

Each of the above operations is performed by operating the operating parts of each mechanism in accordance with the set order according to a command from a separate computer according to a preset program.

(Effects of the Invention) According to the apparatus of the present invention, by driving each part according to a predetermined order and repeatedly performing the cleaning process of the mold and the squeegee and switching the mold, the automatic color paste supplying means In combination with this, it is possible to print continuously and fully automatically. Therefore, if you prepare and supply the required number of color paste adjustments, printing can be done continuously without any manual intervention. The printed test fabrics can then be assembled and transferred to post-processing steps.

Each of the above-mentioned mechanisms is operated sequentially in a predetermined order according to a preset program by a separately installed electric control device, so that each part is operated continuously.

Next, the operation of the device of the present invention will be explained.

Colored paste for color matching is prepared as appropriate by a well-known computer-controlled preparation device, and an appropriate amount of colored paste is placed in a container and sequentially sent to a supply position by a supply container 80. The color paste supplied to a predetermined position by the supply container 80 is sequentially supplied to a predetermined position on the screen 31 of the formwork 30 in a state described later by a suction/discharge nozzle attached to the end of the supply arm of a known color paste supply robot 81. Ru. In this specific example, three color printing molds are formed on the screen 31 of the formwork 30, and one type of color paste is sequentially supplied to each of the printing molds.

On the other hand, the test cloth A is a predetermined cloth from the cloth supply side of the belt conveyor 40, which is continuously placed on the conveying upper surface 41° of the conveying heddle 41 while being stretched. At this time, the conveyor belt 41
An ice layer is applied to the upper surface 41'' of the conveyor, and the test cloth A is made to adhere to the upper surface 41'' of the conveyor with the applied ice layer.

When this test cloth A is fed one set transfer pitch, the jack 17 of the formwork support mechanism 10 is lowered, and the screen 3 of the formwork 30 fixed on the formwork support frame 11 is lowered.
1 comes into close contact with the test cloth.

When the supply of colored glue is finished on the screen 31 of the formwork 30 at the above-mentioned capacity, the squeegee support mechanism 20 is activated, and the squeegee support 24, which had been in the retracted position, is moved back to the formwork by the retracting operation of the movable table 21. 30 is returned above the print start position,
Next, the vertical operation cylinder 27 of the squeegee support 24 operates, and the squeegee 2 is moved through the piston rod 27'.
Lower 3. At this time, the tip of the squeegee 23 is moved back at an appropriate angle with respect to the vertical line via the squeegee holder 28 by a rotary actuator M5 attached to the squeegee support frame 28, and then the squeegee 23 is brought into contact with the surface of the screen 31. The squeegee 23 is lowered, and then returned to a vertical position (it is not necessarily attached to this and may be used in an inclined position) to apply a pressing force suitable for printing. By doing so, the tip of the squeegee 23 is curved to provide cushioning properties, and it is possible to prevent the screen 31 of the formwork 30 from being damaged by the pressure caused by the downward movement of the squeegee 23.

When the squeegee 23 is in a movable position, the electric motor M3
The movable table 21 is moved by the drive of the squeegee support 2.
While applying a constant pressing force to the squeegee 23 via 4,
The colored paste is moved on the screen 31 of the formwork 30 by moving it a required distance and printed on the test cloth.

When the squeegee 23 moves to a predetermined stroke, the vertical operation cylinder 27 of the squeegee support 24 is operated to raise the squeegee 23 above the top of the body frame 2.

Thereafter, the rotating rotary actuator attached to the post 22 is driven in the forward direction to rotate the squeegee support 24 by the support rod 26', and the squeegee cleaning position C
(See Figure 4) Rotate approximately 120 degrees. When the squeegee 23 and its squeegee support frame 28 are moved to this position, cleaning water is sprayed to wash away the colored glue adhering to the squeegee 23. Then, compressed air is blown to remove moisture and the material is dried.

While the squeegee 23 is being cleaned, the jacks 17 of the formwork support mechanism 10 are raised, and the formwork support frame 11 is lifted up via the support base 13.

Then, the formwork 30 supported by the formwork support frame 11 is pulled away from above and lifted onto the printed test fabric. At this time, since the test fabric is pressed against the conveying top surface 41' by the fabric press plates 45 and 45 on both sides of the printing position a, even if the screen 31 of the formwork 30 is pulled apart in the vertical direction, nothing will happen. No problems arise. When the formwork 30 rises, the presser plates 45, 45 release the presser operation, the belt conveyor 40 becomes movable, and the conveyor belt 41 is moved by one stroke to move to the next printing operation mode. . Then, while the next prepared colored paste is supplied onto the screen 31 of a new formwork 30 by the colored paste supplying robot 81 in the above-described manner, the formwork 30 that has completed the printing operation is moved by the rotation device 14. So 180
The formwork 30 is rotated and reversed and moved to the standby position, and the formwork 30 that was in the standby position is placed on the belt conveyor 40 instead. In connection with this, the swing actuator of the squeegee support mechanism 20 is reversely driven, and the squeegee 23 is returned to above the conveyor belt 41 and placed on standby. The screen 31 of the formwork 30 moved to the standby position is sprayed with high pressure water from the cleaning water injection pipe 6 disposed at the position.
The colored paste attached is washed away. At this time, for example, after first cleaning the surface of the screen 3I, the fixing by the fixing cylinder 15 is released, and the rotary actuator 16 is
is activated, the formwork 30 is turned over, and the back side is washed with washing water. For this cleaning, if hot water is used, the cleaning process can be performed with high efficiency. When cleaning is completed, compressed air is injected to remove moisture from the surface of the screen 31 and dry it. During the time period during which the screen 31 of the formwork 30 is being cleaned, colored glue is sequentially supplied onto the three screens of the formwork 30 at the print position, and the processing operations for both are approximately the same in terms of time. It is set up to be balanced.

The test cloth A that has been printed is advanced by a preset distance by driving the belt converter 40, and when the next printed portion moves to the printing position, the printing operation is performed in the same manner as described above. Then, print numbers are printed in order on the printed portions of the test cloth at the printing machine 50 position. This print number is recorded in the storage section of the computer along with the number assigned to the colored glue supplied earlier by a preset electric control mechanism,
It is possible to check which color paste was used during the color matching operation. The test cloth A, which has been sequentially transferred from the printing machine 50 position to the dispensing side, is dried in the next step by blowing hot air from the drying blower 55 to such an extent that no color develops, and then moved to the top surface 41 by the dispensing mechanism 60. is sent out of the device, which consists of

The print operation for colorma notching is continuously and automatically performed repeatedly in this manner. In addition to adhesion using the aqueous phase as described above, in order to allow the test cloth to adhere to the upper surface 41'' of the belt conveyor 40 and be conveyed without causing displacement, an electrostatic adsorption device may be used in addition to adhesion using the aqueous phase as described above. Alternatively, the test cloth may be held by suction on the conveyor belt 41.Alternatively, after printing is completed, the conveyor belt 41
Needless to say, the surface of the conveyor heald 41 after being separated from the cloth and being sent out is wiped with a cleaning brush or the like (not shown) during the return stroke so that the next cloth feeding and conveyance can be carried out in a clean state.
