Abstract
Description
- The present invention relates to a method and a device for separating a screen from the fabric on a flat screen textile printing machine.
- In printing the fabric by a flat screen textile printing machine, a color paste is forced through a screen with a squeegee onto the surface of the fabric to be printed on. For this purpose, the squeegee must be pressed against the screen so as to slightly bend the forward end of squeegee.
- After squeegeeing, the screen remains in a sticky state on the surface of the fabric because of the viscousness of the color paste. Consequently it becomes necessary to peel off the screen from the fabric before subsequent squeegeeing.

- The reason for raising the screen to bring it in an inclined position is to prevent the screen from flipping against the viscosity of color paste by the separation of the screen. If the screen flips, the residual color paste on the screen meshes would be scattered around over the surface of the fabric. The printed textile soiled with the scattered color paste is treated as a defective product.
- The screen should be slowly raised into an inclined position to achieve a satisfactory result according to conventional methods.

The screentextile printing machine 1 is schematically shown as a whole in FIGS. 1 and 2. - In FIGS. 1 and 2, indicated at 2 is a roller for driving an
endless belt 4 for transporting the fabric to be printed on 7; at 3, a driven roller; at 5, a motor for intermittently moving theendless belt 4; and at 6, a printing table. - The screen
textile printing machine 1 hasprinting units 11 arranged side by side with a predetermined spacing on a screen textileprinting machine frame 10. The details of theprinting unit 11 are illustrated in FIG. 3 (plan view). - Means 9 for raising and lowering the screen in the
printing unit 11 has a structure as stated below. - The details of the
means 9 are shown in FIGS. 4 and 5. - An
assembly 118 having ascreen 118b stretched over ascreen frame 118a is connected via thescreen frame 118a to a pair ofsupport bars belt 4, thebars belt 4. - Four
brackets 115 are attached to both ends ofsqueegee guide rails support bars support bars brackets 115 via themeans 9 serving as a joint. - The
means 9 includes an upwardly and downwardlymovable shaft 901, anactuator 903, such as an air cylinder, joined to theshaft 901 by aconnector 902, and a verticallymovable member 905 linked to aplunger 904 of theactuator 903. - The
shaft 901 of themeans 9 is joined by thread connection to a manually turnable adjustingscrew 116 on the bracket 15. Theshaft 901 is ascended and descended by the turn of the adjustingscrew 116, whereby theassembly 118 is raised and lowered by thesupport bars belt 4 and thescreen 118b opposed to the carrier portion can be adjusted by the ascent or descent of theassembly 118. - The
shaft 901 is fitted in the verticallymovable member 905 therethrough. More specifically, theshaft 901 is fitted in a bore formed in themember 905 by way of so-called clearance fit. Themember 905 is ascended and descended by theplunger 904 of theactuator 903, whereby theassembly 118, namely thescreen 118b, is ascended and descended, relative to thefabric 7 over thebelt 4. Crevice-like arms brackets support bars member 905 by apin 906 extending in a direction orthogonal to the squeegeeing direction of asqueegee 114. Thepin 906 is inserted by clearance fit in bores formed in thearms - Since the vertically
movable member 905 is connected to thearms support bars pin 906, thescreen frame 118a is turnable around an axis orthogonal to the direction of squeegee travel at one side and at the other side in the squeegeeing direction or direction of squeegee travel (direction indicated by an arrow in FIG. 3). - The pairs of
squeegees screen 118b, namely in a state of non-squeegeeing, the following squeegee is brought into contact with thescreen 118b to accomplish squeegeeing by pressure. Thesqueegees - In the practice of the invention, while the squeegee is moved forward in contact with the screen, the
screen 118b is raised at the side of start of squeegeeing simultaneously with, or slightly later than, the start of squeegeeing in order to achieve the intended purpose. - The screen can be moved upward for separation from the fabric in the manner described above.
- The following results can be achieved by the method of separating the screen according to the invention.
- According to the method of the invention, the screen is raised with respect to the fabric for the separation of screen in the following manner. The separation of screen is initiated with a squeegee positioned in close vicinity with one end of the
screen frame 118a at the side of start of squeegee travel. Because the squeegee is positioned in close vicinity with one end of thescreen frame 118a at the side of start of squeegee travel, the initial separation of screen occurs at a shorter distance from the starting point than by conventional methods with the screen more inclined and accordingly less or not tensioned. - Consequently the flip of screen is avoided at the moment of separation from the fabric according to the method of the invention unlike conventional methods. After initiation of separation without flipping, the screen is smoothly separated from the fabric by its upward movement in the manner described above while squeegeeing is carried out. Accordingly a satisfactory printing result can be achieved without lowering the operating rate in a printing cycle according to the present invention.
- When the squeegee has advanced to the terminal position, the screen is completely separated. Subsequently after elevation of squeegee, the
screen frame 118a is raised at its end from the other side than the side of start of squeegeeing until thescreen 118b is suspended in the air as a whole together with thescreen frame 118a above the fabric. - FIGS. 6 (A), (B) show the initial stage of squeegeeing and the intermediate stage of squeegeeing and separation of screen, respectively. FIGS. 7 (A), (B) illustrate the final stage of squeegeeing and the complete separation of screen from the fabric, respectively. The color paste is designated 30 in FIGS. 6 and 7.
- The squeegeeing depicted in FIGS. 6 and 7 is advanced from the right side to the left side. The squeegeeing progressing from the left side to the right side is imaginable by substantially reversing the views.
- According to the invention, the assembly of the screen frame and the support member is ascended and descended structurally independently of the other components of the printing unit. Due to this structure, the screen can be easily raised and lowered using a miniaturized actuator in the means for ascending and descending the screen, or in other words, in a simplified and facilitated manner.
- In this way, a satisfactory printing result can be achieved in accordance with the invention without lowering the operating rate in a printing cycle, and the screen can be raised by miniaturized and simplified means for ascending and descending the screen.
