  Further, since the gluing device 10 according to the present embodiment can mount a plurality of machines to one collating machine, in FIG. 9, four gluing apparatuses 10 are provided. In the case of wearing, different operation control is shown.

[Action]
Hereinafter, the operation of the gluing device 10 according to the present embodiment will be described.
In the case of using the gluing device 10 according to the present embodiment, as a premise, the compressed air guided through the compressed air supply pipe 39 is predetermined by the compressed air control unit 41 controlled by the control unit 15. Pressure is introduced into the glue pressurizing tank 23.
Accordingly, the liquid paste stored in the paste pressurizing tank 23 by the compressed air of the predetermined pressure is supplied to the head portion 31 via the paste supply hose 24, and opens and closes the paste supply passage provided in the head 26. The needle valve is closed.

  When operating the gluing device 10, first, as shown in FIG. 8 and FIG. 9, the control unit 15, as shown in FIGS. The distance dimension from the detection of each page 22 conveyed by the sensor unit 14 until the head unit 13 starts discharging glue and the numerical value of the distance dimension until the head unit 13 stops discharging glue are input. To do. When the numerical value setting operation in the control unit 15 is completed, the operation of the gluing device 10 is started.

In this case, the control unit 15 controls the operation of the sensor unit 14 and the head unit 13 based on the set numerical value.
As shown in FIG. 6, the paper feed chain 18 disposed between the conveyance path guide panels 16a and 16b starts rotating by the drive unit, and each page 22 is moved from the paper feed station (not shown). When arranged on the transport path guide panels 16a and 16b, the transport path guide panel 16 is transported to the downstream side while the end portion in the width direction is gripped by the paper feed claw portion 19.

Thereafter, when each page 22 approaches a predetermined distance with respect to the sensor unit 14, the sensor unit 147 detects the approach of each page 22 and sends a signal indicating that the page 22 has been detected to the control unit 15.
When the control unit 15 receives the approach signal of each page 2, the head unit 13 is driven based on the numerical setting conditions set at the start of operation.

  That is, as shown in FIGS. 3 and 7, the slide shutter 36 of the head portion 13 is operated to open the discharge port 43, and the needle valve provided in the head is driven at a predetermined time interval so that the glue supply passage is opened. While opening and closing, the compressed air supplied to the head portion is introduced into the paste supply passage for a predetermined time, so that the liquid paste is discharged to each page 22 conveyed with a predetermined pressure.

The head unit 13 repeats this operation based on the set conditions, and a dot-like paste as a whole extends along the conveyance direction at a predetermined interval (for example, 2 mm interval) at a portion of each page near the rising piece 21. The glue bonding site is formed. The pasting apparatus 10 repeats this operation when the pages 22 are conveyed.
As a result, in the collating machine 11 equipped with the gluing device 10 according to the present embodiment, the gluing work is performed simultaneously with the collating work of each page. A bookbinding operation including a gluing operation can be performed without preparing a separate collating and pasting machine.

  As shown in FIG. 5, the head 26 can be protruded further inward along the arm portion 29 and along the width direction of the conveyance path guide panel 16 as necessary. As described above, when the head 26 is arranged and used in advance, for example, it is possible to cope with a case where bookbinding such as bag binding is necessary, and various kinds of requests corresponding to various bookbinding requests. The gluing operation can be performed easily and quickly in the collating machine.

  Therefore, in the gluing device 10 according to the present embodiment, since the joining portion is formed for each page by the discharge of the glue from the head unit 13, the wire rope is removed from the conventional glue storage box. Unlike the case where the glue is physically attached to each page by supplying the glue via the disk and contacting the disk member to each page, the glue adheres to each page in a non-contact state, unlike the case using the disk member. Since there is no contact resistance to the paper, misalignment is unlikely to occur during conveyance of each page.

  Further, in the conventional collating and pasting machine, at the end of the work, cleaning work for the glue storage box, the wire rope, the disk, etc. is indispensable. However, in the gluing apparatus 10 according to the present embodiment, the head Since the glue can be attached to each page in a physically non-contact state by the portion 13, the cleaning work is not necessary, and the labor required for maintenance can be reduced.

In the present embodiment, the case where only one gluing device 10 according to the present invention is mounted on the paper transport path 12 has been described as an example. However, the present invention is not limited to the above embodiment, and a plurality of units are mounted. May be.
In addition, the attachment part of the gluing device 10 can be attached to an appropriate part without being restricted by the position of each sheet feeding station of the collating machine.
Further, the specific configurations of the head unit, the sensor unit, and the control unit are not limited to the present embodiment.

  The present invention can be widely applied to a gluing device that can be detachably attached to a collating machine.
