Embodiment Construction

[0027] The present invention will be described in detail below according to the drawings and embodiments.

[0028] Press the command button on the keyboard 2 to control the glue applicator 4 or the screen to control the glue applicator 4, and the corresponding coil of the glue applicator 4 will be energized. If the air pump 6 can supply air pressure normally, the glue in the pressure cooker 5 will be It flows out through the glue applicator 4 along the pipeline. This function is used when the device is debugged and cleaned.

[0029] The rotary encoder 1 is connected to the pulse input end of the high-speed counter of the programmable controller 3, and the output of the photoelectric sensor 8 is connected to the interrupt signal input end of the programmable controller 3. When the workpiece D to be bound moves to the detection position of the photoelectric sensor 8 with the folder, the photoelectric sensor 8 is triggered, and the sensor 8 sends a signal to the interrupt receivi...

Abstract

The present invention discloses a gluing device for a paper folding machine and the gluing method of spraying glue at the position of paper folding and banding, which belongs to the banding industry. The device comprises: a transmission belt and a transmission shaft of the transmission mechanism of the paper folding machine, and the device further includs: an input unit, a programmable controller(3), a rotating coder(1) contacted with the transmission shaft, and a gluing head(4) and a photoelectrical sensor(8) arranged at the top of the transmission belt. The gluing method comprises: a continuous method of coating a section of glue or glue with different length on the workpiece along a straight line, or a pulsation method of coating a plurality of sections of glue with same length and same discontinuous distance on the workpiece along the straight line. The device has a simple structure, adopts common components mostly with low cost, and eliminates the banding method of steel saddle binding, thus realizing different gluing methods of continuous method and pulsation method, with good gluing effect, high working efficiency, the device is especially suitable for banding the slim booklet with few pages.

Description

(1) Technical field [0001] The invention relates to an accessory device of a folding machine in the printing and binding industry and a working method thereof, in particular to a device and a method for spraying glue on a specific position of folding and binding before folding. (2) Background technology [0002] At present, the general knife folding machine, fence folding machine, and fence knife hybrid folding machine on the market all use the method of saddle stitching by wire after folding. Using such a method requires the use of saddle stitching wire materials; in addition, saddle wire stitching sometimes damages the equipment and knives when the shredded binding is opened, and it takes more procedures to remove the saddle stitching; when recycling waste paper, remove the saddle stitching wire Also increased the process. Therefore, need to have a kind of binding method that is suitable for booklet that is thin, few pages, and avoids using wire saddle stitching again. ...
