Overall Operation> The embodiment of the present invention is constructed in a diagonal manner, and its operation will now be described.

When using the fully automatic coating and drying machine of the present invention, the coating device 50
In the pressure coating mechanism 140 in , a roller unit 146 is set when a cut emulsion film F is used, and a bucket unit 147 is set when coating only with emulsion. In addition, depending on the size of the plate frame S, there is also a support mechanism 55 in the coating device 50, a film supply device 90 for selecting the cut emulsion film F, and a drying device 17.
The carry-in mechanism 185, the carry-out mechanism 205, the film peeling device 240, and the discharge device 280 in 0 are automatically determined and controlled and operated.

First, the loading frame rack 10 is fixedly set in the loading device The plate frame S is flanged and lifted and transferred to the side of the coating device 50 (Figs. 1 and 2).
(see figure).

When transferring, if the plate frame S is supported and set in the coating device 50 by its support mechanism 55, the loading support mechanism 3
1 waits in front of the coating device [50] until the plate frame S is transferred from the support mechanism 55.

When the loading support mechanism 31 loads and sets the plate frame S at the support mechanism 55 position in the coating device 50, the support mechanism 55 supports and fixes the plate frame S upright from above and below in accordance with its size. After the support l is fixed, the damage detection mechanism 71 is activated to detect whether there is any damage in the screen mesh of the frame S (see Figure 10), and if there is any damage, the frame S is transferred to the frame. The mechanism 160 removes it from the cargo covering 250. If the screen mesh is not damaged, the pressure coating mechanism 140 is activated to start coating the screen mesh.

At this time, when cut emulsion film F is used, the film supply device! At 90, either the small cut emulsion film F on the upper table 98 or the large cut emulsion film F on the lower table 1010 is selectively supplied depending on the size of the plate frame S (see FIGS. 5 and 6).

At this time, the film carriage mechanism 105 of the film supply device 90 adsorbs and takes out a predetermined cut emulsion film F with a suction pad 123 from the film storage mechanism 95 in which cut emulsion films F of different sizes are stacked and set separately. During this suction, the air ejected from the air nozzle 104 separates the films F on the hole side, takes out only the required cut emulsion film F, and removes dust and other particles adhering to the cut emulsion film F. That's what I do.

And film storage I! When the cut emulsion film F taken out from 195 is brought into contact with and supported by the film carriage mechanism 105 on the screen mesh surface of the printing frame S, the press coating mechanism 140 rises once and applies the lower end portion of the cut emulsion film F to the screen mesh surface. Make it stick to the surface. After the close contact, the pressure coating mechanism 140 descends and rises again to apply the emulsion film of the cut emulsion film F together with the emulsion supplied from the emulsion baguette 156 onto the screen mesh surface in a transfer form.

On the other hand, when applying the emulsion directly, the bucket unit 147 is selectively installed at the pressure coating selection position 45, and when the pressure coating al ellipse 140 itself rises, the emulsion is applied together with the emulsion bucket 156 at the coating position 55. Apply to the screen mesh surface.

Selection of the coating mechanism and coating form, changes in coating film thickness on the squeegee surface or print surface of the screen mesh, changes in the number of coatings, settings for coating or scraping on either surface, etc. It is controlled and adjusted by each switch on the control panel 54.

The cleaning mechanism 165 removes and cleans the emulsion adhering to the tip edges of the bucket unit 147 and the emulsion bucket 156 after the coating operation is completed.

When the coating operation is completed, the frame S is halfway transferred to the entrance 172 of the drying device 170 by the frame transfer mechanism 160 (see FIGS. 1 and 12).

In the drying device 170, the loading machine 11Il 85 or the printing frame S is pulled into the drying device 1f170 and positioned between the support blocks 183 of the conveyance chain 182 at the upper and lower parts of the conveyance m treetop 181. Thereafter, the conveyance mechanism 181 During the conveyance, the emulsion applied to the screen mesh is dried;
3, the unloading mechanism 205 that had been waiting runs and lifts the lifting means 211 from the lower conveyor chain 182.
Lift up the printing frame S with the upper conveyor chain 182.
The plate frame S is pulled out by the pull-out means 221 from the exit 1.
Carry it out to position 73. At the exit 173, the horizontal ejection means 231 ejects half of the printing frame S to the outside of the exit 173 (see FIG. 15).

The half-ejected plate frame S has a film peeler! The plate frame traveling support mechanism 241 of 240 travels and carries out the printing frame in front of the exit 173. At this time, if it is detected that the film base material is stuck to the plate frame S because it protrudes outside the plate frame S, the film clamp traveling mechanism 251 is activated (the first
(See Figure 8).

That is, when the upper and lower portions of the protruding portion are clamped by the upper and lower film clamps 256 and 257 and run backward, together with the locking collar roller 244 that supports the film application side of the plate frame S and rotates freely, Peel the film base material from the screen mesh surface.

In this way, the printing frame S, which is half-ejected and transported while the film base material is peeled off or the cut emulsion film F is not attached, is transported to the ejection device 28.
0 to the outside of the drying device 170, and the alignment mechanism 2
91, the printing frame racks 10 prepared for ejection are stored in an aligned state (see FIGS. 1 and 20).

(Effects of the Invention) The present invention is configured as a steamer, and the plate frames S are stored in an aligned state in the plate frame rack 10 for loading, and the plate frame rack 10 is fixedly set in the loading device 20. By simply doing this, the cut emulsion film F is automatically applied in the form of a transfer of the emulsion film or the emulsion is directly applied to the screen mesh of the frame S, and after drying, the cut emulsion film F is used. In this case, the film base material is peeled off from the screen mesh surface of the plate frame S, and the coated plate frame S is stored in an aligned state in the plate frame rack 10 for discharge.

That is, in the present invention, when a predetermined printing plate is produced by applying an emulsion to the screen mesh surface of the plate frame S in the coating device 50, a cut emulsion that has been cut in advance to a predetermined size by the film supply device 90 is used. The film F can be automatically supplied, and the cut emulsion film F can be applied to the screen mesh surface while being pressed by a roller unit 146 selectively mounted in the pressure coating mechanism 140.

Moreover, since the cut emulsion film F to be supplied is cut in advance to a predetermined size, there is no need to cut it at the time of supply, and no dust such as chips is generated due to the cutting. Since the air nozzle 104 of the film supply device 90 injects air to the cut emulsion film clamp from the front of the cut emulsion film substrates set in layers, it not only improves separation of the cut emulsion film substrates but also improves the separation of the cut emulsion film substrates. In addition to removing the dust that had adhered to the F, it also eliminates the adhesion of dust to the screen mesh surface, making it possible to improve the precision and evenness of emulsion coating as printing plates for screen printing become more dense. ~ is also of great help.

The film storage mechanism 95 of the film supply device 90
is equipped with upper and lower tables 98 and 101 that are slidable and removable so that multiple types of cut emulsion films F of various sizes can be held in a laminated tiered manner. For printing frames S of multiple sizes, the emulsion film F is cut into multiple sizes and is prepared in advance, and the selection set is made in accordance with each size.
can be used.

Further, the film carriage mechanism 105 of the film supply device 90 moves up and down along the vertical direction of the coating device 50, and tilts and swings so as to face the surface of the film storage mechanism 95 or the surface of the plate frame S, Since the suction pads 123 that adsorb the cut emulsion film F are arranged,
The cut emulsion film F is taken out one by one from the film storage mechanism 95 and supplied to the screen mesh surface of the plate frame S.
This ensures close support of the cut emulsion film F to the screen mesh surface.

On the other hand, the pressure coating mechanism 140 includes a roller unit 14 that presses the cut emulsion film F onto the screen mesh surface.
6 or bucket unit 1 for supplying or scraping emulsion
Press application selection position 4 where one of 47 is selectively attached
5 and a coating position 55 equipped with an emulsion baguette 156 for supplying emulsion to the screen mesh surface or scraping off the emulsion. Direct coating of the emulsion allows for the selection of any used coatings.

Furthermore, according to the present invention, when pasting the cut emulsion film F, the cut emulsion film F is pressed and held against the screen mesh surface, and when the emulsion is directly applied, the cut emulsion film F is pressed against the screen mesh surface or the print surface. The thickness of the coating film, the number of coatings, etc. can be adjusted, and the coating mechanism and coating form can be selected, making it easy to produce a variety of screen printing plates.

In addition, the peeling device 240 uses the cut emulsion film F to peel off the film base material of the emulsion film (F) attached to the screen mesh surface from the plate frame S after drying. When applied, only the film base material can be peeled off smoothly and quickly. That is, the plate frame traveling support mechanism 241 allows the plate frame S to run along the opening direction of the plate frame S itself, and slides and supports the film attachment surface of the plate frame S, and the plate frame running support mechanism 241 supports the film sticking portion of the plate frame S. A film peeling device 240 constituted by a film clamp traveling mechanism 251 that clamps and runs away from the film pasting surface on the film pasting surface side while being clamped.
By attaching this to the outlet 173 of the drying device 170, only the film base material can be automatically peeled off from the plate frame S after drying.

Furthermore, this film peeling device 240 is equipped with a film upper edge support mechanism 265 that pinches and supports the upper edge of the film base material peeled from the plate frame S, thereby facilitating the smooth arrangement of the peeled film base materials. It is possible to aim for

And again, the installation! 20 and roller unit 146
FF 50 includes a pressure coating mechanism 140 having a pressure coating selection position 45 and a coating position 55 to which either a bucket unit 147 or a bucket unit 147 is selectively attached, a film supply device 90, a drying device 170, and a film peeling device. Attire! 2
40 and a discharge device 280, the coating of the plate frame S can be applied to the plate frame S in order to achieve precision and evenness of emulsion coating as printing plates for screen printing become more dense. A series of operations such as loading the film into the apparatus 50, applying a high-density emulsion using the cut emulsion film F, drying after applying the emulsion, and peeling off the film base material can be completely automated.

Therefore, according to the present invention, emulsion coating can be made more precise and uniform as printing plates for screen printing become more dense, and it is possible to improve the precision and uniformity of emulsion coating as the printing plate for screen printing increases in density. Its selection, high-density emulsion coating, drying,
Ejection, peeling and removal of the film base material, etc. can be performed automatically without any manual effort, and it is fully automated, resulting in excellent effects such as appropriately obtaining printing plates for screen printing.
