Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to stack a plurality of printed continuous slips, apply an adhesive liquid to the edge along the longitudinal direction thereof, and bond them together. The present invention relates to a gluing device for a collating machine.

[Prior art]

Conventionally, the gluing device of this type of collator is provided at the tip of the hose branched on the side of the gear pump discharge port provided on the glue tank at the glue application part of each sheet of the continuous slips running on the collator. It is known that the nozzles are opposed to each other, and the adhesive liquid is supplied from the discharge side through a hose to the nozzles opposed to each other by a rotation of a gear pump to apply the adhesive liquid.

[Problems to be solved by the invention]

The gluing device of the known collator is used for gluing a running continuous slip through a hose with a gear pump provided on the adhesive liquid tank side, and the adhesive liquid flowing through the hose is discharged from a nozzle provided at the tip. Although it is supplied and applied, if you want to stop the gluing work for some reason, even after stopping the gear pump, a large amount of adhesive remains inside the hose to the nozzle, and this adhesive liquid It flows from the nozzle and falls on the voucher to stain the voucher, which creates a voucher that cannot be used.
It becomes uneconomical. In the past, pasting is performed by a gear pump on the side of the adhesive solution tank that continuously supplies the adhesive solution from a nozzle that faces the voucher, but in some cases it may be applied in spots at intervals. However, in the case of overlapping or stacking a large number of sheets, for example, it may be desired to skip and apply at the perforated portion, etc., but since the nozzle is fixed, in such a case it becomes a complicated structure, so there is a demand. I couldn't respond.

[Means for solving problems]

In view of such circumstances, the present invention was devised to eliminate these problems, that is, the nozzle attached to the gear pump main body is connected to the discharge port, and the suction port of the main body is connected to the adhesive liquid tank. Connect to the other end of the hose with one end connected,
Moreover, the nozzle of the gear pump main body is supported by the support shaft and the swing shaft corresponding to the application portion of the continuous slip, and swings through the swing shaft by using a proper swing means such as a cam plate if necessary. To apply lines, dots, and reliefs, eliminating waste of slips and loss of adhesive liquid.
Furthermore, the purpose is to apply an adhesive solution according to demand.

Rotating shaft 8 and actuating member 18 described later
The main body 1 is supported by the operation 18a of.

The rotating shaft 8 is provided with a gear 12 that meshes with the gear 7, and a sprocket is attached to the outside of the machine frame 11 of the rotating shaft 8 so that the rotation from the drive source is sprocketed by a chain or the like via a speed change mechanism. The rotation is transmitted to the gears in the main body 1 by contacting them. That is, the pump action is performed.

A pin 16 is provided in the upper portion of the main body 1 in the lateral direction, and this upper portion is further provided with an operating arm 18 from an operating member 18 which is loosely fitted via a bush to an oscillating shaft 17 which is horizontally supported between the machine frames 11.
The operation arm 1 of the holding portion is fitted into the tip holding portion 28 of a.
The pin 16 is fitted in the notch groove 27 provided in the 8a to support the main body 1 described above.

Further, the actuating member 18 has a vertical hole 18b and a lateral pin hole 18c which is orthogonal to the vertical hole 18b and which passes through the vertical hole 18b. The pin 20 provided at the tip of the arm 19a from the mounting member 19 mounted on the swing shaft 17 is inserted into the pin hole 18c, and the pin hole 18c is a long hole along the vertical hole 18b. , The spring 21 housed in the vertical hole 18b and the adjusting screw 22 screwed from the end
Thus, the pin 20 is clamped so as to perform a cushioning action.

At one end of the swing shaft 17, an actuating piece 23 that acts on the cam plate 24 when swinging the main body 1 is attached. Further, the operating piece 23 is provided with a tension spring 25 so as to come into contact with the cam plate 24, and the rotation of the cam plate 24 gives a swinging motion to the swing shaft 17 via the operating piece 23.

Although the swing motion of the swing shaft 17 is given by the cam plate 24, it may be electrically performed by a computer or the like, and is not limited to the cam plate.

[Action]

In the present invention, as is apparent from the above configuration, the continuous paper is machine frame 11
It is fed through a roller 26 provided with a feed pin and a guide roller, and in the meanwhile, a gluing device is positioned corresponding to the continuous paper and supported by an operating arm 18a of an operating member 18 of a rotary shaft 8 and a swing shaft 17. , The gears 2 and 3 in the main body 1 are rotated by adjusting the speed of the drive from the drive source by the speed change mechanism to suck the adhesive liquid in the adhesive liquid tank 14 from the suction port 6 through the hose 15 and to the discharge port 5. Adhesive liquid is continuously applied linearly on the continuous paper surface which is discharged from the communicating nozzle 13 and runs, and the applied continuous paper overlaps with other continuous paper and is polymerized and adhered by a pressing roller arranged at the end. Is. Further, in order to adhere the dots in a spaced manner, the operating piece 23 is attached to one end of the swing shaft 17, and the cam plate 24 for operating one end of the operating piece 23 is attached. By swinging the swinging shaft 17 through the arm, the actuating member 18 is swung through the arm 19a from the mounting member 19 attached to the swinging shaft 17, and the main body 1 is rotated by the actuating arm 18a. The nozzle 13 is swung to the center, and the nozzle 13 attached to the main body 1 is contacted and separated from the continuous paper to apply the adhesive liquid at intervals.

The cam plate 24 applies various coatings to this interval.

〔effect〕

According to the present invention, as described above, the discharge side of the pump main body having the pair of rotor gears built therein is connected to the nozzle attached to the main body, and the other suction side is connected to the tank containing the adhesive liquid through the hose. Further, the nozzle is made to correspond at the adhesive application position of the continuous paper which is guided and guided by the guide roller, and a notch groove is provided in the lower portion of the main body, and the notch groove is fitted and supported on the rotary shaft and rotated. The shaft is provided with driving means for transmitting rotation to the gears of the rotor, and the upper part of the main body is provided with an arm and a pin from an attachment member attached to a swing shaft that swings when necessary by an appropriate means such as a cam plate. A glue device in a collator that connects the working arm of a working member connected through a pin via a pin so that the bonding liquid ejected from the nozzle of the main body can be applied to the continuous paper in a linear or dot shape. Is
Corresponding the nozzle attached to the gear pump body with continuous paper,
Since the hose from the adhesive liquid tank is connected to the suction port of the main body, the discharge from the nozzle will stop immediately if the gear pump is stopped, and the nozzle will bond even after the gear pump is stopped as in the conventional bonding device. The liquid does not drip. Therefore, since it does not fall on the continuous paper, there is no waste and the loss of the adhesive liquid can be prevented.

Further, since the main body can be rocked by using the rocking means, it is possible to apply not only to the linear shape but also to the dot shape at intervals, and it is also possible to partly skip and adhere. When a large number of sheets are piled up, there is an effect that the adhesive portion does not become bulky.
