Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a gluing device such as a device for manufacturing postcards and envelopes from printed continuous forms.

Conventional technology Print out postcards using a computer,
In order to make efficient use of printers when manufacturing envelopes, we use a general form of continuous form during printer processing, and use a pressure roller (back-up roller) to glue the necessary parts of the continuous form after printing. Individual postcards and envelopes are manufactured by pressing the paper against a roller to partially apply glue and then folding it to form a continuous postcard or envelope, which is then cut.
When gluing in this way, if the machine is stopped, the form will stick to the surface of the gluing roller, and if the machine is restarted, the form will be torn or jammed in that area, and the torn part of the form will become stuck. This also caused the adhesive to adhere to the pressure roller side, causing the pressure roller to become dirty with glue.

Problems to be solved by the invention This invention, when applying glue to the necessary parts of a continuous form after printing, separates the pressure roller and the form from the surface of the gluing roller when the device is stopped. To provide a gluing device that can eliminate adhesion to the surface of a gluing roller, thereby eliminating damage to forms, tear jams, and preventing contamination of a pressure roller.

Means for Solving the Problems The present invention provides a guide roller and a support roller that are provided adjacent to each other at the tip of a swingable support rod, and the continuous form that is pulled out while being applied with tension,
The support rod is guided by a guide roller installed on the support shaft of the support rod, and the pressure roller presses the gluing roller to apply gluing, and when the gluing device is stopped, the support rod is separated from the gluing roller. By swinging the continuous form in the direction to separate it from the surface of the gluing roller, the form is prevented from adhering to or being damaged by the gluing roller, and furthermore, the pressure roller surface is not contaminated. The purpose of this is to attach the following information.

Function A pressure roller adjacent to a guide roller installed at one end of a swingable support rod presses the necessary areas of the continuous form that moves under tension against the glue roller to perform the gluing operation. When the machine is stopped, the support rod is swung in a direction away from the gluing roller to keep the form passing between the pressure roller and the guide roller away from the surface of the gluing part roller, and the gluing operation is performed. Abort.

Example Embodiments of the present invention will be described with reference to the drawings.

The drawings show an apparatus for producing continuous postcards and continuous envelopes according to the present invention, in which Fig. 1 is a side view, Fig. 2 is a perspective view, Fig. 3 is an enlarged view of the gluing device shown in Fig. 1, and Fig. 4 is an enlarged view of the gluing device shown in Fig. 1. The figure is a plan view of the tension device, and FIG. 5 is a cross-sectional view of the folding guide shaft.

This device is provided with a paper feed stand 3 on the lower side of the machine casing 1 for placing the folded continuous form 2, and the continuous form 2 pulled out from this is guided by a guide roller 4, After guiding the liquid from the glue pot 9 to the tension device 8, which is made up of a pair of rollers 5 and 6 that can rotate with two shafts as a fulcrum, and fitted with guide pieces 7 and 7 that regulate the left and right positions of the continuous form. The continuous form 2 is pressed by the pressure roller 14 to the gluing roller 11, which is supplied with glue via the pick-up roller 10, to be glued. A support rod 15 is provided which can swing around a support shaft 12 and has a guide roller 13 and a pressure roller 14 at the other end, so that the pressure roller 14 is in contact with the gluing roller 11 during operation. It is composed of In addition, a support shaft roll 16 is provided coaxially with the support shaft 12 of the support rod 15, and the continuous form 2 due to the movement of the support rod 15 is
The staff determines the location and guides the next step.
Further, the amount of glue adhered to the glue roller 11 is adjusted by the doctor 17.

The continuous form 2 pulled out from the paper feed tray 3 is applied with tension by the tension bar 8, and at the same time, its horizontal position is regulated by the guide pieces 7, which can be adjusted from side to side. The continuous form 2 is guided between the provided guide roller 13 and pressure roller 14, and the continuous form 2 is pasted by the pressure roller 4 acting to press the continuous form 2 against the gluing roller 11. ing.

When the operation of the apparatus is stopped or the form is torn or lost, the support rod 15 is swung about the support shaft 12 and moves to the state shown by the dotted line in FIG. 3. At this time, the guide roller 13 is
4, it provides tension to the form 2 inserted between both rollers, and serves to quickly separate the form 2 from the gluing roller 11 at the same time as the swinging. This effect is particularly effective when the tension of the tension bar 8 on the paper feeding side is weak. Remove any tears in the form 2, replenish the form 2, and set the form 2 between the guide roller 13, pressure roller 14, and support roller 16 while the support rod 15 is moved (the state shown by the dotted line in Figure 3). Simultaneously with the start of the movement of the apparatus, the support rod 15 is swung about the support shaft 12 to move the pressure roller 14 to a position where it comes into contact with the gluing roller 11.

To further explain the overall configuration, a guide roll 18 is further provided above the spindle guide roll 16, and conical pieces 19, 19 inclined toward the outer end are fitted diagonally above the guide roll 18 on the left and right sides. A folding guide shaft 20 is provided in parallel, and here, the continuous form 2 is folded in half by having both side edges curved inward and pulled upward, and the center line of the continuous form is folded into a frame 21. The paper is folded by being guided to be sandwiched between the paper and the paper, and is then completely folded by the two rotatable guide rollers 22 provided orthogonally to the guide rollers and the like.

The continuous form folded in this way is provided in a state perpendicular to the gluing part, and is made up of two sets of an upper roll 23 with a partial notch in the longitudinal direction and a lower roll 23 without a notch. The applied glue portion is adhered by the press roll section 24 provided with two sets of.

What has been explained above is how to apply glue to a continuous form and fold and collate it in half.The mechanism up to this point is an independent device, and then a well-known buster (a paper feeding device using a marginal punch, a marginal part slitter) is used. A postcard or an envelope shape may be obtained by connecting two devices (consisting of a bursting device and a bursting device that performs separation using horizontal perforations), or they may be constructed integrally.

Effects In this invention, we are trying to manufacture postcards and envelopes by folding the continuous forms while applying glue after printing them out, so if we apply glue to the continuous forms in advance before printing. like,
Not only is there no restriction from the printer's printing method or fixing method, such as glue adhering to the printer head, but it also prevents the contact of the form and pressure roller with the gluing roller when the machine is stopped or when the printer is stopped. When a form is lost or torn, the support rod is swung and released, eliminating adhesion of the form to the surface of the glue roller and contamination of the surface of the pressure roller with glue, making it easy to reach the necessary areas. Gluing is performed properly and uniformly, and furthermore, when setting the form, the support rod is placed at a position separated from the gluing roller, making the setting operation easier. In addition, since adhesion is performed well by the subsequent press treatment, it is possible to prevent poor glue drying and curling of the product after processing, and it is possible to obtain a good product.
