Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paste for attaching a mount having a predetermined size and a continuous roll sheet on which printing, photographs, etc. are described or photographed at predetermined intervals to a predetermined position. The present invention relates to an adhesive application nozzle used in an apparatus.

[0002]

2. Description of the Related Art Conventionally, there is an example in which a photograph is pasted on a government-made postcard in order to convey the current situation such as a New Year's postcard, and if these were developed and pasted one by one, at most several There is a limit to the production of dozens of sheets, the cost is high, and the production time is a big loss. For this reason, Japanese Patent Publication No. 5-49038 has filed a patent for a method of producing a postcard using a photograph on one side, and the present inventor has also used a photograph on one side in Japanese Patent Laid-Open No. 5-131782. Has applied for and has already been published with respect to a device for attaching a postcard to a strip-shaped photograph.

However, in Japanese Patent Publication No. 5-49038, in the description of its operating portion, it is stated that the base surface side of the photographic strip is coated with glue while moving the photographic strip in one direction. In 131782, as will be described later, liquid glue is applied to the back side of the band-shaped photograph by means of a glue applying unit.

That is, it is obvious that liquid paste is adhered and pasted over the entire surface of the continuous roll sheet.

Further, in Japanese Patent Laid-Open No. 63-70858, in the embodiment, the adhesive applied by the adhesive sticking means is exposed on all the portions of the back surface of the photographic paper to which the residual frame is not attached after punching. are doing. It is stated that the adhesive is attached to the entire surface of the continuous sheet.

A conventional technique will be described below with reference to the drawings. FIG. 11 is a cross-sectional view for explaining a transfer method that is generally widely used for the method of attaching an adhesive, FIG. 12 is a view showing a pasting device for attaching a postcard to a conventional strip photograph, and FIGS. It is a figure which shows the other example about adhesive application in a schematic diagram.

In FIG. 11, (51) is an adhesive tank, and (5)
2) is an adhesive, and liquid glue is generally used.
(53) is a roller which is rotating around the roller shaft of (54) and a part of which is contained in the adhesive (52). Further, (55) is a transfer roller, (56) is a transfer roller shaft, and (57) is a continuous roll sheet. The transfer rollers of the rollers (53) and (55) have a gap corresponding to the thickness of the adhesive and rotate in the directions of arrows (58) and (59). Then, the continuous roll sheet similarly travels in the direction of the arrow (60).

Next, as another example of application of an adhesive, FIG.
(66) is a continuous roll sheet feeding roll,
(62) is a continuous roll sheet, (63) is an adhesive application part, and (64) is a part which makes an adhesive semi-dry. Further, (65) is a portion for supplying an adherend (herein referred to as a postcard), and (66) is a pressure roller for a continuous roll sheet and an adherend, and thereafter, a pre-cut section, a post-cut section, It is configured as an operation panel and a continuous device.

FIG. 13 is an explanatory view of the adhesive applying section (63), in which (67) is an adhesive applying nozzle and (68) is an adhesive applying roller. Further, (69) is a rotation support base, (70) is a sliding contact roller, and (72) is a rotation center of the rotation support base (69). Reference numeral (71) is an elevating mechanism section for adjusting the height of the sliding contact roller (70) so that the adhesive application section (63) comes to an optimum position where it comes into contact with the continuous roll sheet (62). And continuous roll sheet (62)
The adhesive application port (68) is in contact therewith, and the adhesive is supplied.
Further, FIG. 14 shows a state in which the rotation support base (69) of FIG. 13 is rotated by 180 ° with respect to the rotation center (72). In this case, the continuous roll sheet (62) is not in contact with the adhesive application port (68), so that the adhesive is not supplied.

[0010]

However, in the conventional technique, the adhesive is applied over the entire width of the continuous roll sheet, and the thickness of the adhesive cannot be controlled, and the continuous roll sheet has The upper surface, that is, the surface opposite to the adhesive application surface, is printed or photographed at a predetermined interval, so the entire surface of the adhesive layer is used for positioning with the sensor etc. when attaching the adherend. The adhesive is exposed in four areas of the adherend that has been applied over.

Further, in addition to the roller (66) for sticking and fixing the adherend, the guide roller for running the continuous roll sheet passes through the exposed portion of the adhesive on the four sides, so that the guide roller becomes dirty. Also, if dust adheres to the exposed adhesive part, or if it progresses further,
There has been a problem that the surface of a continuous roll sheet such as a printed matter or a photograph or an adherend is also soiled.

Further, in FIGS. 13 and 14, the rotation support base is rotated so that the adhesive application port is rotated during the running of the continuous roll sheet, so that the motion is intermittent, that is, the running speed of the continuous roll sheet. When the number of rotations per unit time of the rotation support base is always constant, it is possible to intermittently make the part to which the adhesive adheres on the continuous roll sheet by setting the conditions, and There is also a problem that exposed parts of the adhesive are generated only on both side surfaces.

[0013]

Means for Solving the Problems The present invention provides an adhesive only on a continuous roll sheet and on a portion having an adherend, that is, a portion to which the adherend is attached on a continuous roll sheet. The exposed part of the adhesive was removed while the patch was stuck.

[0014]

[Function] That is, since the exposed portion of the adhesive is completely eliminated, the pressure roller for fixing the adherend to the continuous roll sheet, the guide roller of the continuous roll sheet, etc.
Not only will dust not adhere, it will be possible to always work in a clean state, and it will also lead to a reduction in man-hours.

Further, as shown in FIG. 4, the rotation center hole may be penetrated in order to allow the adhesive to flow from both ends of the coating nozzle. Further, the adhesive application port (4) is connected to the inner cylinder. Then, the adhesive supplied to the inner cylinder comes out from the application port (4). Further, W has a width equal to or slightly smaller than the width of the adherend.

FIG. 3 is a sectional view taken along the line AA 'in FIG. 2, in which the entire surface of the adhesive coating nozzle (1) except the range of θ comes into contact with the continuous roll sheet (9). Therefore, (7) is a tangent line between the short side of the L-shaped adhesive groove (5) and the circumference of the outer peripheral portion and forms an acute angle. Similarly, (8) is a tangent line between the long side and the circumference of the outer peripheral portion, which is an obtuse angle. Then, the adhesive application port (4) is provided on a part of the long side. (10) indicates the center position of the bearing portion (3) of the nozzle (1).
Reference numeral (11) is an arrow indicating the rotation direction of the coating nozzle (1), and the L-shaped adhesive groove (5) is always the long side of (8) with respect to the running of the continuous roll sheet (9) during the rotating operation.

Range of contact points (13)-(13) 'between 2) and outer circle,
That is, the range of the angle θ with respect to the center position (10) is the range not in contact with the continuous roll sheet (9).

Next, FIGS. 6 and 7 show a state diagram when the coating nozzle (1) is rotating. In FIG. 6, a state in which the continuous roll sheet is in deepest contact, FIG.
Indicates the state where the continuous roll sheet is not in contact.
That is, as shown in FIGS. 6 and 9, by rotating the coating nozzle (1) once, a portion where the adhesive is applied and a portion where the adhesive is not applied (range of θ) can be obtained. Further, (14) and (15) are guide rollers for continuous roll sheets.

FIG. 8 is a diagram showing the state of application of the adhesive on the continuous roll sheet (9), Wp is the full width of the continuous roll sheet (9), and E and F are the adherends (16). The dimensions are shown, and in the part of the continuous roll sheet (9), (17) shows the part to which the adhesive is not applied, and (18) shows the part to which the adhesive is applied. Furthermore, E'and F '
Shows the size of the part to which the adhesive is applied, and the adhesive is applied, which is equal to or slightly smaller than the sizes E and F of the adherend (16).

FIG. 9 is a plan view of the adhesive coating nozzle (1) of FIG. 1, showing in detail the minute uneven surface (6) provided over the entire circumference of the coating nozzle portion. (1
9) is a surface parallel to the coating nozzle (1), and (2)
0) is a taper surface for adjacent parallel surfaces. That is, the parallel surface (19) and the tapered surface (20) form a saw-tooth shape, and the blade edge is continuous. The height h of the cutting edge that makes minute irregularities is 0.2 mm to 0.5 mm, the height of the L-shaped adhesive groove (5) is H, and the end thereof comes into contact with the outer peripheral portion. The width of the L-shaped adhesive groove of (5) is almost the same as that of the adherend E ′. Further, FIG. 10 is a partially enlarged sectional view of the plan view of FIG. As shown in FIG. 10, the taper surface (20) is processed so as to be symmetrical at a substantially central portion of the width W of the L-shaped adhesive groove (5). The adhesive application port (4) is arranged on the bottom surface (21) of the L-shaped adhesive groove (5).

The operation will be specifically described below. Liquid adhesive is mainly used as the adhesive used in the present invention. Since this adhesive is also water-soluble and loses its adhesive force when the adhesive is dried, a material that can be regenerated by steam is also used. ing. Then, at a predetermined position of the continuous roll sheet, is it equal to the width of the adherend,
Or, it relates to an adhesive application nozzle for applying an adhesive with a slightly smaller width and a size equal to or smaller than the length of the adherend, and the adhesive applied at that time The thickness can be made uniform.

That is, in FIG. 1 and FIG. 2, the adhesive supplied from the adhesive supply port is filled in the supply hole formed at the center of rotation of the coating nozzle and further blown out from the coating port of the adhesive coating nozzle. Become. At this time, the center of rotation of the coating nozzle that is in sliding contact with the continuous roll sheet is eccentric in order to obtain a minute gap between the adherends when the coating nozzle makes one rotation as shown in FIG. Thus, the adhesive does not adhere to the continuous roll sheet at the portion of θ, and the adhesive adheres to the other portions because the coating nozzle makes sliding contact with the continuous roll sheet. Moreover, at this time, the tangent line between the short side of the L-shaped adhesive groove and the circumferential portion of the outer peripheral portion is an acute angle, and a constant tension is applied to the continuous roll sheet, so that the adhesive is not applied. The thickness can be made uniform at the acute-angled tangent portion, and the length W of the L-shaped adhesive groove is W ≦ Wp, so that when the pasting target is pasted, both sides of the pasting target No adhesive will stick out on the surface. Similarly, by adjusting the running speed of the continuous roll sheet and the rotation speed of the coating nozzle also in the longitudinal direction of the adherend, the adhesive can be attached at the same or slightly shorter time as the adherend. Therefore, the adhesive is not exposed between the adherends.

Further, FIGS. 3, 4 and 5 are views showing an adhesive application port in the adhesive application nozzle, wherein the adhesive application port is divided into a plurality of portions which are slidably contacted at one place or a continuous roll sheet, It is possible to provide adhesive application ports at a plurality of locations, which is the same number as the number of divisions, except for the position away from the continuous roll sheet. At this time, the diameter of the adhesive application port is φ0.
4 to 1.2 mm and the pitch is 0.5 to 1.5 m
m. According to the examples, when the number of application ports is one, good results are obtained when the diameter of the adhesive application ports is φ0.8 and the pitch of the application ports is 1 mm. still,
If the application ports are provided at multiple locations, the diameter of the application port x π
The diameter obtained by dividing the area of the coating port by a plurality of values at a plurality of locations or the diameter obtained from an area 20% larger than the diameter. This is because, when the water-soluble adhesives that are adhesives have the same viscosity, the fluidity deteriorates as the application port becomes smaller.

Further, the reason why the application port is L-shaped is
The adhesive blown out from the application port collects in the triangular portion surrounded by the continuous roll sheet at the L-shaped portion, and the adhesive adheres as the continuous roll sheet surface travels. Since the angle at which the single part of the L-shaped processed part and the external part intersect is an acute angle, it works to scrape off the adhesive adhering to the surface of the continuous roll sheet to a predetermined thickness, so that the adhesive layer is always present. Can be made uniform.

Next, the unevenness of the saw blade-shaped parallel portion and the tapered portion is provided over the entire surface in parallel to the circumferential direction of the adhesive application nozzle. The width W of the L-shaped processed part of the coating nozzle
Adhesive adheres in a parallel width at the parallel saw blade tops, but at the taper portion, the adhesive is slightly attached to the surface of the coating nozzle, but the position is lower than the saw tops, so The adhesive does not adhere to the continuous roll sheet that is in sliding contact with the blade-shaped top. Further, since the sawtooth-shaped minute irregularities are formed on the entire surface, the adhesive does not flow out to other portions except the L-shaped processed portion. At this time, the height of the minute irregularities does not exceed 0.5 mm at the maximum, and the pitch is 0.5 mm or less.

Since the coating nozzle is eccentric with respect to the center of rotation and the outer peripheral portion, the outer peripheral portion excluding the range shown in θ (see FIG. 3) is in sliding contact, but the θ portion is not in slidable contact, and therefore the adhesive is not applied. It will not adhere. Further, the sliding contact with the continuous roll sheet is also eliminated from the place where the L-shape processing is also performed with the point where the outer circumference circle of (13) is in contact with θ as a base point. Ie L
The adhesive does not spread beyond the width W of the groove that has been shaped like a letter. Furthermore, it is said that the present inventor has consecutively described a large number of shallow grooves in the circumferential direction of the surface of the cylindrical body in the claims of Japanese Patent Publication No. 3-156455, and in the explanatory view, it is a concavo-convex pattern in which arcs are continuous, Although this method may be used, in the present invention, the taper direction is made symmetrical with respect to the substantially central position of the L-shaped processed portion W of the coating port, whereby the ends of the L-shaped processed portion are parallel to each other. In the case of the portion or the tapered portion, the diameter is smaller than that of the parallel portion, so that even if the adhesive adheres, the adhesive does not spread and adhere beyond the width of the adherend.

In FIG. 4, the rotation center hole is penetrated in order to allow the adhesive to flow from both ends of the coating nozzle.
Shows a cross-sectional view in the case where the coating port is provided at one farthest position on the outer periphery decentered from the center of rotation. 21 is a rotation direction in which the coating nozzle intermittently rotates, and 22
Indicates the moving direction of the continuous roll sheet.

In this embodiment, the continuous roll sheet is running at a predetermined running speed, and the coating nozzle is rotated intermittently. That is, FIG. 5 is a state diagram in which the adhesive is applied to the continuous roll sheet,
In a state where the adhesive is applied only in an arbitrary range for a predetermined length, the running speed of the continuous roll sheet and the applying nozzle are rotated so as to match the rotating speed of the applying nozzle. Since the coating nozzle is rotated by setting the time so that it can be coated in an arbitrary range, continuous coating is possible and continuous work can be performed even if the image captured on the continuous roll sheet changes. This leads to a reduction in man-hours.

[0030]

EFFECTS OF THE INVENTION According to the present invention, since the adhesive used for sticking the adherend to the continuous roll sheet does not come out from the adherend, the adhesive does not adhere to the guide roller. Therefore, it does not stain the surface of the adherend,
Further, cleaning after using a guide roller or the like for running the continuous roll sheet is also simplified, and the number of steps can be shortened and stains on the apparatus can be removed.

Further, by intermittently rotating the coating nozzle, the work can be continuously continued even if the image picked up on the continuous roll sheet is changed, and the number of man-hours is greatly reduced.
