Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention aims to improve the precision and uniformity of emulsion coating as the density of printing plates for screen printing increases. This invention relates to an automatic emulsion coating and drying machine for screen printing printing plates, which automatically performs feeding into a device, high-density emulsion coating, drying, and discharge.

(Prior Art) Conventionally, printing plates for screen printing are formed by applying an emulsion to a predetermined film thickness and drying the emulsion.

That is, the emulsion is supplied from a bucket to the screen (gauge) formed in the mesh shape of the printing plate, and then applied.
When the emulsion reaches a predetermined thickness, it is dried.

For this reason, when applying the emulsion manually, the coating film thickness will be uneven, but this is done by mechanical means (for example, as proposed by the present applicant in Japanese Patent Laid-Open No. -4
8044, 60-188949). Also,
Drying is carried out by exposing the material to hot air while transporting it in a suitable dryer.

(Problem to be solved by the invention) However, in conventional equipment and methods, the coater and dryer are configured completely independently, and the printing plate as a semi-finished product after coating is transported to the dryer. and placed in the dryer manually. In addition, the dryer is operated to dry the product while being transported in the dryer, and after drying, the product is removed from the dryer and stored in a predetermined location, which is also done manually.

According to these conventional systems, even if it is possible to automatically process coating and drying, it is difficult to automatically process the entire process because it involves labor-intensive work. It was troublesome to transport the items to the dryer, organize and store them after removing them from the dryer.

Especially these days, in various types of screen printing, including printing of print 1 to circuit boards, the thickness of the applied WA and the resulting tightness of the entire product due to drying have a great effect on the printed matter after printing. A high degree of precision is required in setting the film thickness.

Therefore, the present invention was created in view of the existing circumstances as described above, and is intended to improve the precision and uniformity of emulsion coating in accordance with the increasing density of printing plates for screen printing. The purpose is to be able to automatically perform loading, high-density emulsion coating, drying, and ejection without human intervention, and to be able to fully automate the process to properly obtain printing plates for screen printing. do.

[Means for Solving the Problems of the Invention] In order to achieve the above-mentioned object, in the present invention, the plate frames that are arranged and stored in the input plate frame rack are arranged one by one. A loading device that takes out and transfers, and a plate frame transferred by this loading device is supported and set at a predetermined coating position,
A coating device that applies emulsion to the screen of the plate frame, a drying device that dries the plate frame after coating while transporting it, and a discharge device that stores and aligns the plate frame after drying in a plate frame rack for ejection. It is characterized by comprising the following.

(Function) In the automatic emulsion coating and drying machine for screen printing printing plates according to the present invention, a plate frame rack for loading is fixedly set in the loading device, and the loading device is operated.

The loading device takes out the plate frames one by one from the plate frame rack, travels, and transports them to the coating device.

When the plate frame is loaded and set in the coating device, the plate frame is supported and fixed in an upright position, and after the plate frame is supported and fixed, the emulsion is applied to the screen of the plate frame. When the coating operation is completed, the plate frame is transferred to a drying device.

In the drying device, the emulsion coated on the screen is dried while being transported. When drying is completed, the plate frame is discharged from the drying device.

The ejected printing frames are stored in a lined state in a printing frame rack prepared for ejection by a hanging device.

−12= <Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

<General outline> In the automatic emulsion coating and drying machine of the printing plate for screen printing according to the present invention, the plate frames S stored in advance in an aligned state in the plate frame rack 10 are taken out one by one by the loading device 20 and coated. The coating device 50 is loaded and set in the device 50, and in the coating device 50,

The plates are dried while being conveyed within the drying device 120, and after drying is completed, they are automatically discharged from the drying device 120 via the discharge device 180, and stored and stored in an aligned state in the discharge frame rack 10. It is.

As shown in FIG. 1, the overall arrangement is such that a drying device 120 is arranged long in the left and right at the rear, and an inlet 122 is opened on the left side of the side wall in front of the drying device 120, and the drying device 120 is disposed in the vicinity of this population 122. A device 50 is arranged, and this coating device 50
A loading device 20 that can move forward and backward with respect to the coating device 50 is arranged at the front side of the central portion of the drying device 12O, and a plate frame rack 10 is movably placed within this loading device 20. . Further, an outlet 123 is opened on the right side of the drying device 120, and a discharge device 180 and a movable plate frame rack 10 for discharge are arranged near the outlet 123.

<Print frame rack> The plate frame rack 10, which stores a large number of plate frames S in parallel in a substantially erected form, is movable on casters provided on the bottom, and can be moved with respect to the loading device 20 and the coating device 50. The drying device 120. It is fixedly supported to the charging device 20 by suitable ramp means provided on the installation surface or elsewhere.

The plate frames S stored in the plate frame rack 10 are arranged so as to be stored at fixed positions in the plate frame rack 10, for example, so as to converge at one corner when viewed from above. In the illustrated example, the plate frame rack 10 is supported in a erected manner by a support frame 11 formed in a substantially L-shape in a plan view at the front and right sides so as to be focused at the front right corner. The support frame 11, which is roughly L-shaped in plan, is a latch for loading and unloading the plate frame S at the left side and rear part of the plate frame rack 10 in conjunction with the drying device 120 and the ejecting device 180.

Overview of loading device> In order to take out plate frames S stored in alignment in the plate frame rack 10 one by one and transfer them to the coating device 50, a loading device is used. 20
The loading support m-tree 31 is configured to be movable so as to reciprocate between the coating device 50 and the plate frame rack 10.

This feeding device 20, as shown in FIGS. 2 to 5,
A traveling rail 23 laid between the upper part of the coating device 50 and the upper part of the support column 21 installed on the right side of the frame rack 10
The plate frame S is placed on the input carriage 25 which can freely run along the
A charging support machine [31] which removably clamps the loader is provided so as to be movable up and down.

The pillars 21 are arranged with an interval large enough to set the frame rack 10 between them and the coating device 50, and a pair of left and right rail mounts 2 are installed between the pillars 21 and the upper part of the coating device 50.
2 is positioned with respect to the coating device 50, and the traveling rail 23 is laid on this rail frame 22.

Feeding Carriage of Feeding Device> The feeding carriage 25, which travels along the rail mount 22, is driven by the driving force of a traveling motor 24 disposed above the coating device 50, and is controlled within a predetermined travel range and speed. The input carriage 25 itself is formed into a substantially rectangular shape when viewed from the front by thick plate frames 26 on the upper and lower sides and on the left and right sides so as to surround the rail mount 22.

Loading Support Mechanism of Loading Device> The loading support mechanism 31 connects a positioning lift cylinder 33 to the lower end of a lift cylinder 32 that is fixed by penetrating the upper and lower plate frames 26, and fixes a clamp frame 34 to the lower end of this positioning lift cylinder 33. do. A guide base 36 guided by guide rollers 35 provided on the left and right plate frames 26 is erected on the top of the clamp frame 34.
A plate frame clamp part 41 for correcting both sides of the plate frame S is provided at the lower end of the clamp frame 34.

The elevating cylinder 32 is large, and its elevating distance is long enough to take out the plate frame S supported by the plate frame clamp section 41 from the plate frame rack 10. In addition, the positioning lifting cylinder 33 is a small one,
The plate frame S is applied to the coating device 5 by the movement of the feeding carriage 25.
The lifting distance is short enough to lower it when setting it to a predetermined position within 0. Reference numeral 37 in the figure is a joint that connects the elevating cylinder 32 and the positioning elevating cylinder 33.

When viewed from the front, the clamp frame 34 is located at the bottom end or the printing frame S.
It is formed in an open shape that is larger than the left and right width of the coating device, and is also formed in a crank shape having a stepped portion that is slightly curved when viewed from the side. This is to make it easier to set the plate frame S in a predetermined position, since the input carriage 25 itself cannot enter the interior of the coating device 50 even if the input carriage 25 moves to the side of the coating device 50. be.

The guide roller 35 has a guide groove with a V-shaped cross section, and this guide groove is fitted into the chevron-shaped protruding edges on both sides of the guide base 36 to prevent wobbling when the clamp frame 34 moves up and down.

As shown in FIG. 3, the plate frame clamp section 41 is provided with jig cylinders 43 on the left and right sides, each of which has a clamp head 42 for clamping, inside near the lower end of the clamp frame 34, and below the jig cylinders 43 on both sides of the plate frame S. An auxiliary auxiliary jig cylinder 45 having a guide block 44 sandwiching the auxiliary jig cylinder 45 is provided. A rubber pressure bonding pad is arranged at the tip of the clamp head 42 to serve as a protection portion for the plate frame S. Further, the guide block 44 has a cross-sectional groove shape into which the side frame of the plate frame S is fitted, and when the clamp frame 34 is raised or lowered after the plate frame S is fixed by the operation of the jig cylinder 43, the clamping is done at one point. Since it is a support, the frame S is supported almost vertically by its own weight. After the frame is supported in a nearly vertical position, the auxiliary jig cylinder 45 is actuated to fix the side frame with the power side block 44, thereby preventing the shake of the plate frame S during feeding, and preventing the movement of the plate frame S in the coating device 50, which will be described later. to ensure that it is set in place. - At this time, the strokes of the left and right jig cylinders 43 are different. That is, in FIG. 3, the jig cylinder 43 on the left side has a shorter stroke than that on the right side.

Therefore, even if the left and right jig cylinders 43 start operating at the same time, the left jig cylinder 43 hits the plate frame S, and then the right jig cylinder 43 hits the plate frame S, so that at the clamping support position of the plate frame clamp part 41, It is always held at a fixed position where it is clamped by the jig cylinder 43 on the left side.

Therefore, when the plate frame S is set in the coating device 50, it is fixed without any positional shift from side to side, and the coating [1]
The coating operation by the bucket 91 of 85 is made smooth.

Further, at the lower end of the clamp frame 34, a deceleration sensor 48 for deceleration is provided at a position near the guide block 44, that is, located beside the pillar 21. This deceleration sensor 48 detects when the input carriage 25 approaches the plate frame S when it moves backward so as to support and clamp the plate frame S to be coated next, and reduces the running speed of the input carriage 25. (See Figures 4 and 5).

Note that the guide block 44 only needs to prevent the plate frame S from wobbling during transportation, so it is sufficient to use a guide block that straightens the side frames of the plate frame S from both sides (not shown).
.

In addition, this installation! When transferring the plate frame S in step 20, if the plate frame S is fixedly set by the support mechanism 55 in the coating device 50, the input support mechanism 31 transfers the plate from the support device [55] in front of the coating device [50]. It waits until the frame S is transferred to avoid wasting work time.

<Overview of coating device> The plate frame S transferred by the loading device 20 is transferred to the coating device 5.
The emulsion is set at a predetermined coating position within 0, and the emulsion is coated on the screen surface of the plate frame S.

As shown in FIGS. 6 to 13, this coating device 50 includes a support mechanism 55 that supports and sets the plate frame S, a damage detection mechanism 71 that detects damage to the screen of the plate frame S that has been supported and set. It comprises a coating mechanism 85 that applies emulsion to the screen surface of the frame S, and a frame transfer mechanism 101 that discharges and transfers the damaged frame S or the frame S after coating.

<Flowchart of overall operation> The embodiment of the present invention is constructed as described above, and its operation will now be described with reference to flowcharts shown in FIGS. 23 to 26.

In this flowchart, in order to ensure continuous work, unprocessed printing frames S are stored in the input printing plate rack 10 or processed printing frames S are stored in the printing plate rack 10 for ejection. When there are fewer than five spaces left, a warning is issued and the entire operation is not carried out until the preparation is completed, but this can be set as desired.

First, load the plate frame rack 10 for loading! 20 and operate the charging device 20. The loading carriage 25 of the loading device 20 runs, and the loading support mechanism 31 operates to clamp and lift the plate frame S in the plate frame rack 10, and transfer it to the coating device 50 (see FIG. 23).

When transferring, the support mechanism 55 in the coating device 50 supports the plate frame S.
If the plate frame S is set to be supported, the loading support mechanism 31 waits in front of the coating device 50 until the plate frame S is transferred from the support mechanism 55.

When the plate frame S is loaded and set at the support mechanism 55 position outside the coating device 50 by the loading support i mechanism 31, the support mechanism 55
Now, the printing frame S is supported and fixed in an upright position.

After the support and fixation, the damage detector #i71 is activated to detect the presence or absence of damage on the screen of the frame S. If there is any damage, the frame S is transferred to the coating device 5 by the frame transfer mechanism 101.

At this time, the cleaning mechanism 105 removes and cleans the emulsion on the tip edge of the bucket 91 after the coating operation is completed.

When the coating operation is completed, the frame S is partially transferred to the entrance 122 of the drying device 120 by the frame transfer mechanism 101 (see FIG. 24).

In the drying device 120, when the carry-in mechanism 135 or the plate frame S is pulled into the drying device 120 and positioned on the conveyance mechanism 131, the conveyance mechanism 131 conveys it, and during the conveyance, the emulsion coated on the screen is dried. When drying is completed and the drying process reaches the vicinity of the exit 123, the waiting unloader mechanism 151 runs, lifts the frame S on the transport 81111131, and discharges half of the frame S from the outlet 123.

The half-ejected printing frames S are pulled out of the drying device 120 by the ejection device 180, and are stored in an aligned state in the printing frame rack 10 prepared for ejection by the operation of the descending alignment machine 1I4201. (See Figure 26).

[Effects of the Invention] The present invention is configured as described above, 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 loaded into the loading device 20. By simply setting them in a fixed position, the emulsion is automatically applied to the screen of the plate frame S, and after drying, they are stored in an aligned state in the plate frame rack 10 for discharge.

This includes a loading device 20 that takes out and transports plate frames S arranged and stored in a loading plate frame rack 10 one by one, and this loading device! A coating device 50 that supports and sets the fine plate frame S transferred by the plate frame S at a predetermined coating position and coats the screen of the plate frame S with emulsion, and a drying device 120 that dries the plate frame S after coating is completed while conveying it. This is because it includes a discharge device 180 for storing and arranging the plate frames S after drying in the plate frame rack 10 for discharge.

Therefore, according to the present invention, it is possible to achieve precision and uniform emulsion coating as the density of printing plates for screen printing increases, and it is possible to achieve precision and evenness in emulsion coating as the density of printing plates for screen printing increases.
Drying and discharging can be performed automatically without any manual effort, and it is fully automated, resulting in excellent effects such as being able to properly obtain printing plates for screen printing.
