Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic screen printing machine for double-sided printing.

[0002]

2. Description of the Related Art Conventionally, various types of automatic screen printing machines which convey a plurality of printing tables in a horizontal annular shape and perform one-sided multicolor printing of sewing clothing have been devised and marketed. For example, JP-A-59-42958 and JP-A-61-13
4256 and Japanese Utility Model Laid-Open No. 3-20148. In these methods, after the sewing, clothing such as gloves is attached to the printing table 1 so that the printing object 19 is attached to the printing table 1 having an original size and a hand shape. The printing table 1 is detached so as to be pulled out, the gloves are turned upside down, and the printing table 1 is worn again. At present, it is difficult to automate the attachment / detachment of an object to be printed to / from the printing table 1, and the work is manually performed. Therefore, double-sided printing takes twice as much work as single-sided printing,
The cost is high and work is flowing to foreign countries where labor costs are low.In addition, when trying to print a pattern over the entire surface of both sides, due to the circumferential mounting distortion when re-installing, the remaining The fact that the tip of the pattern appears slightly on the printed surface means stepping on the pattern, which in turn results in non-printed parts, resulting in a high non-up rate and uniform product. Absent.

[0003]

SUMMARY OF THE INVENTION According to the present invention, the number of times of manually attaching / detaching a printed material to a printing table during the printing process for sewing garments as described above is reduced by half, and the work is performed efficiently. The purpose of the present invention is to reduce the cost, reduce the cost drastically, eliminate the circumferential pattern deviation on both sides, and improve the yield by uniformizing the products.

[0004]

According to the present invention, the printing table is made reversible, and the above-mentioned objects can be solved by the following means.

In the automatic screen printing machine 17, the printing table 1 is fixed to a flan # 3 provided on one side of the shaft end of the reversing shaft 2, and the flan # 3 is separated from two cam floors 4 protruding right and left about the reversing shaft 2. The base 7 is rotatably supported by a rotary bearing 6 via a chain 5, and the gantry 7 is provided with a lower rail 8 which engages with the cam floor 4, a gate 9, and a switch 15 for opening and closing the gate. The printing table can be reversed by the reversal mounting 10 acting upon reversing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 is a plan view, FIG. 2 is a front view, FIG. 3 is a side view, and FIG. 4 is a schematic plan view of the entire automatic screen printing machine.

【Example】

The mount 7 is provided with a reversing device 10 via a bracket 11 and a mounting shaft 14 via a bracket 13, and the gate 9 which rotates about the mounting shaft 14 is supported via the bracket 13. Switchgear 1
It is opened and closed at 5. Further, the stand 7 is provided with a chain 5 via a chain guide rail 12, and the chain 5 is provided with a plurality of rotary bearings 6.

The printing table 1 is fixed to a flan # 3 provided on one side of the shaft end of the reversing shaft 2, and the flan # 3 is provided with two cam floors 4 projecting right and left about the reversing shaft 2.
Is provided, and is engaged with the rotary bearing 6 via the reversing shaft 2 so as to be rotatably supported.

The reversing device 10 pivotally supports the shaft end of the reversing shaft 2 with the pawl 16, and the gate 9 is opened by the switch 15. After the reversing device 10 is rotated by 180 degrees, the gate 9 is closed by the switch 15. The pawl 16 of the reversing device 10 is released. Thus, the plain printing gloves 19 to be printed are first inserted into the plurality of printing tables 1 which have been sequentially moved to the fixed positions by the chain 5, and then printed at the next fixed positions by the palm side printing machine 17a. At the next fixed position, the back is turned upside down by the first reversing device 10a, the back side of the hand is turned upward, and the printing machine 17b for the back of the hand is printed at the next fixed position, and the dryer 2 is set at the next fixed position.
At 0, a drying time is taken. At the next fixed position, the reversing device 10b performs reversal for returning to the back side of the hand, air-cools at the next fixed position, and at the next fixed position, the printing table 1
The glove 18 which has been further pulled out and which has been pulled out after double-sided printing has been completed is completed, thereby completing one cycle.

[0011]

According to the present invention, the movement of the printing table is sequentially driven by a chain or the like to stop at a fixed position, and after one-side printing of the sewn product mounted on the printing table, automatic reversal is sequentially performed at the fixed position. By printing on the printed surface, double-sided printing can be performed easily, the number of times of attachment and detachment can be reduced by half, the cost can be greatly reduced, and the mounting deviation in the circumferential direction can be completed because each product can be installed once. There is no print, so there is no misregistration, and the printing on both sides is beautifully finished, the added value is improved, and the yield can be greatly contributed to.
