DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for sealing a booklet such as a catalog, pamphlet or magazine.

[0002]

BACKGROUND OF THE INVENTION As a means for sending a catalog by mail or courier, as shown in FIG. 10A, a small edge C1 of a catalog C (a free end located on the opposite side to the back C2) is adhered. It has been considered that the tape is sealed by being wrapped with the tape T, and a name or the like is printed on the surface of the adhesive tape T. This delivery method does not require the use of envelopes,
It can significantly reduce the cost of sending and contribute to the reduction of garbage, and is expected as a new means of sending booklets. In addition, the opening of the catalog C is performed with the adhesive tape T
, Or the adhesive tape T is cut off at the edge C1.

As a means for sealing the forefront C1 of the catalog C with the adhesive tape T, as shown by an arrow A in FIG. 10 (B), the catalog C is extended along the traveling direction. While transporting, As shown by a dashed line, the adhesive tape T is fed out in an upright state, and is folded back and forth on both sides of the catalog C by a guide member (not shown); As indicated by the two-dot chain line, a method is conceivable in which the adhesive tape T is fed out to the lower surface of the catalog C while lying down, and the protruding portion is folded toward the surface of the catalog C.

[0004]

However, FIG. 10 (B)
Is a method in which the adhesive tape T is fed out and gradually folded back from its end. Since the adhesive tape T is stably deformed in an unstable state and is stuck to the catalog C,
If the feeding speed of the catalog C is increased to a certain level or more, there is a problem that the sealing failure in which the adhesive tape is clogged in the guide member occurs frequently.

[0005] More specifically, in the method of FIG.
Due to friction between the adhesive tape T and the catalog C, an external force is applied to the adhesive tape T so that the adhesive tape T can be pushed and bent in the advancing direction of the catalog C. When the feeding speed of the catalog C increases, the catalog C and the adhesive tape T And the friction between the adhesive tape T and the pressure-sensitive adhesive tape T is increased, and the pressure-sensitive adhesive tape T is deformed into a crushed state inside the guide member.

Further, since it is difficult to match the timing of transporting the catalog C with the timing of feeding the adhesive tape T, the position of the adhesive tape T is often shifted, and wrinkles are more likely to occur because the adhesive tape T is easily deformed. Therefore, there is a problem that the appearance of the catalog C after sealing is poor, in other words, the quality of the adhesive tape T is not good.

[0007] Further, there is another problem in that the movement of the adhesive tape T is complicated, so that the structure of the apparatus is correspondingly complicated. An object of the present invention is to solve these problems.

[0008]

According to the present invention, a booklet such as a catalog or a pamphlet and an adhesive tape having an adhesive layer formed on one side thereof are arranged such that the adhesive layer of the adhesive tape faces the edge of the booklet. After the arrangement, the two were relatively moved in a direction perpendicular to the edge of the booklet, so that the adhesive tape was stuck on the front and back surfaces of the booklet.

Further, the apparatus of the present invention comprises a booklet conveying means for conveying a booklet such as a catalog or a pamphlet with the fore edge of the booklet first, and an adhesive tape so as to cross the conveying path of the booklet. And a tape feeding means. Note that the booklet to which the present invention is applied may be a state in which at least two sheets are integrally connected at the back, and the name of a catalog, a pamphlet, a magazine, a printed matter, a book, etc. does not matter.

[0010]

According to the present invention, the pressure-sensitive adhesive tape is simultaneously folded around the small edge of the booklet as a fulcrum.
Adhesive tapes are to be attached to booklets by simple deformation.Moreover, adhesive tapes simply stick to the surface of booklets by falling down on the surface of the booklets. An external force such as crumpling does not act, and together, the booklets can be transported at high speed without causing sealing failure.

Therefore, according to the present invention, the efficiency of the sealing step can be remarkably improved in sealing the small edge of the booklet with the adhesive tape. Further, since the operation is merely a simple operation of feeding out the adhesive tape in the transport direction of the booklets, the entire apparatus can have a simple structure. Furthermore, since the alignment between the booklet and the adhesive tape is easy, high-speed operation is possible, while the accuracy of the adhesive tape attaching position is high, and the adhesive tape is instantaneously placed on both sides of the booklet at the same time. Since the adhesive tape can be attached, the adhesive tape can be attached in a tight state without wrinkles, and together with the high positioning accuracy of these adhesive tapes and the ability to attach in an unwrinkled state, There is also an advantage that the quality of sealed booklets can be significantly improved.

Next, an embodiment in which the present invention is applied to a method and an apparatus for sealing a catalog C will be described with reference to the drawings. FIG. 1 is a schematic plan view of the sealing device 1. The sealing device 1 is provided with a fixed table 2. The table 2 has a booklet transporting means 3 for transporting the catalog C lying down with its fore edge C1 first, and traverses the transport path of the catalog C. In such a state, a tape feeding means 4 for intermittently feeding the adhesive tape T is provided ("means" may be called an apparatus or a mechanism).

First, the tape feeding means 4 will be described with reference to FIGS. 2 (A) is a schematic perspective view of the entire tape feeding means 4, FIG. 2 (B) is a schematic perspective view of a part of the tape feeding means 4, and FIG. 3 (B) is a BB view of FIG. 3 (A), FIG. 4 (A) is an enlarged plan view of a part of the tape feeding means 4, and FIGS. 4 (B) and 5 (A) are partial perspective views. FIG. 5 (B) is a sectional view taken along the line BB of FIG. 5 (A).

As shown in FIG. 2A, the tape feeding means 4
Cuts the adhesive tape T wound into a roll into a predetermined length while intermittently feeding the tape, and feeds the cut to a position where the traveling direction of the catalog C is interrupted. A pair of feed rollers 5, a first press roller 6, a first guide roller 7, a tension box 8, a second guide roller 9, and a second press roller 10 are arranged in this order. The adhesive tape T is a second press roller. 10 is transferred to a pair of upper and lower first feeding belts 11 and cut to a predetermined length by a hot wire type cutter 12, and then a pair of upper and lower second feeding belts 13 extending across the transport path of the catalog C. Move to

As shown in FIG. 3B, the feed roller 5 is driven by a motor (not shown) and is formed in a comb shape. This is because the adhesive tape T is easily peeled and fed. The first pressing roller 6 is pressed against the feed roller 5 by a spring, and can be separated from the feed roller 5 against the spring. In FIGS. 1, 2, and 5, the tension box 8 is indicated by a dashed line, and FIG.
Are shown by solid lines. As shown in FIG. 3 (A), the tension box 8 is opened toward the first and second guide rollers 7, 9 so that the adhesive tape T can enter therein. (Hose and pipes are fine)
Are connected, and the duct 14 is connected to a suction fan F (a vacuum pump may be used). Therefore, the first and second
The adhesive tape T stretched over the guide rollers 7 and 9 is sucked into the tension box 8 and becomes largely slack in a U-shape in plan view.

The tension box 8 includes an adhesive tape T
A pair of first sensors 15 such as a photoelectric type for detecting the position of
When the adhesive tape T is not located between the first sensors 15, the feed roller 5 is driven to feed out the adhesive tape T, and the adhesive tape T is placed between the first sensors 15. If it is located, the feeding by the feed roller 5 stops.

As described above, the tension box 8 has a buffer function for storing the adhesive tape T with a slack, thereby reducing the influence of the inertia of the apparatus and reducing the pressure of the adhesive tape T at a high speed. It can be moved to one feeding belt 11. Note that a tension roller may be used instead of the tension box 8, but if the tension box 8 is used as in the embodiment, the adhesive tape T
Of the pressure-sensitive adhesive tape T can be smoothly fed at a high speed.

As shown in FIGS. 4 and 5, the first feeding belt 11 is wound around first pulleys 18 provided at upper and lower ends of first and second rotating shafts 16 and 17, respectively. 2 rotating shafts 17
Power is transmitted from the second motor 19 by the first timing belt 20. Accordingly, when the second motor 19 is driven, the adhesive tape T is adhered to the first feeding belt 11 via the second pressing roller 10 and is moved in the direction of the second feeding belt 13. In this case, the first feeding belt 11
It is set so as to be located slightly inside the upper and lower edges of the adhesive tape T.

An idle shaft 21 is provided near the first rotary shaft 16, and the first rotary shaft 16 is attached to the idle shaft 21 via an adjuster bolt 22 extending horizontally. Accordingly, the tension of the first feeding belt 11 can be adjusted by rotating the adjuster bolt 22 to move the first rotating shaft 16 farther from the idle shaft 21. The space above and below the first rotating shaft 16 is a space.

As shown by the dashed line in FIG.
The 17, the second motor 19, and the idle shaft 21 are mounted on a rotatable frame 23 that can be horizontally rotated around the axis of the second rotating shaft 17. This is to facilitate setting of the adhesive tape T. A third pressing roller 24 is disposed at a position opposite to the idle shaft 21 with respect to the feeding path of the adhesive tape T, and a cutter 12 is disposed between the second pressing roller 10 and the third pressing roller 24. doing.

As shown in FIG.
A link 25 capable of rotating horizontally around the axis of the press roller 24 is attached, and the link 25 is attached to the second press roller 10.
And the second pressing roller 10 is pressed by a spring (not shown) so that the second pressing roller 10 comes into close contact with the first rotating shaft 16 and is freely used.
For example, as shown in FIG.
The cylinder 26 with the piston rod 26a facing forward is attached. Then, as clearly shown in FIG.
A bifurcated tape-holding metal fitting 27 extending laterally above and below the first rotary shaft 16 is attached to the piston rod 26a by an appropriate means such as screwing. The upper end and the lower end of the metal fitting 27 extending laterally are set so as to overlap the upper and lower edges of the adhesive tape T. Note that a roller may be provided at the upper end and the lower end of the metal fitting 27, and the adhesive tape T may be pressed against the second pressing roller 10 via the roller.

Accordingly, when the cylinder 26 is driven, FIG.
As shown in FIG. 7, the link 25 rotates while the adhesive tape T is sandwiched between the metal fitting 27 and the second holding roller 10, and the second holding roller 10 separates from the first rotating shaft 16, and accordingly, When the adhesive tape T is partially peeled off from the first feeding belt 11 and retreats, the adhesive tape T is
Is cut by touching.

As means for facilitating the setting of the adhesive tape T, instead of rotating the first feeding belt 11 backward, the second to fourth pressing rollers 10, 24, 29 and the cutter 12 are used. You may comprise so that it can slide to this side. Needless to say, another drive mechanism such as an electromagnetic solenoid can be used instead of the cylinder 26. As shown in FIG. 3, a second sensor 28 for detecting the tip of the fed adhesive tape T is provided near the second rotation shaft 17.

In the vicinity of the second rotation shaft 17, the second rotation shaft
A fourth pressing roller 29 for adhering the adhesive tape T to 17 is provided. As shown in FIGS. 2 and 5, the second feeding belt
13 is a third rotating shaft arranged on the opposite side of the second rotating shaft 17 from the second rotating shaft 17 with respect to the transport path of the catalog C.
30 and is wound around a second pulley 31 provided at
Power is transmitted from the second motor 33 to the rotating shaft 30 by the second timing belt 32.

In this case, as shown in FIG. 5 (B), the second pulley 31 is rotatably fitted on the second rotary shaft 17, so that the second rotary shaft 17 is rotated by the first motor 19. However, the second pulley 31 does not rotate. For this reason, the adhesive tape T
At a position close to the second rotation shaft 17. When the first motor 19 and the second motor 31 are driven synchronously, the first and second pulleys 18 and 31 rotate at the same peripheral speed, and the adhesive tape T moves from the first feeding belt 11 to the second feeding belt 13. Then, the pressure-sensitive adhesive tape T is in a state where the pressure-sensitive adhesive layer (glue surface) faces the edge C1 of the catalog C being conveyed.

The second feeding belt 13 is set so as to adhere to the upper edge and the lower edge of the adhesive tape T. Also,
An idle roller is provided near the second rotating shaft 17 and the third rotating shaft 31.
34 are provided to reduce the interval between the second feeding belts 13.
The driving means of the feeding belts 11 and 13 is not limited.

FIG. 6 is a sectional view taken along line VI-VI of FIG. 1. The booklet conveying means 3 includes a pair of front and rear feed rollers 36 extending along the feed direction of the catalog C, and a front and rear feed roller 36. It has a pair of tape guide rollers 37 arranged and an upper and lower guide member 38 for preventing the catalog C from being turned up. The feed roller 36 is driven by a motor (not shown).

The upper feed roller 36, the tape guide roller 37 and the guide member 38 are fixed to the table 2 via a bracket, while the lower feed roller 36
The tape 36, the tape guide roller 37, and the guide member 38 are attached to the lifting frame 39. The lifting frame 39 is attached to the machine frame with a screw shaft 40 partially shown in FIG. 6 so as to be adjustable in height. When the handle 41 shown in FIG. 1 is rotated, the lifting frame 39 moves up and down. Thereby, according to the thickness of the catalog C, the vertical feed roller 36 and the vertical guide member 38
Can be adjusted.

The booklet transporting means 3 is provided with a pair of upper and lower third sensors 42 and fourth sensors 43 for detecting the catalog C. A stacking section 45 is provided in front of the booklet transporting means 3. As shown in FIG. 1, the table 2 is provided with a guide frame 44 for holding the posture of the catalog C at an adjustable interval. Feed roller C for catalog C
Various means can be adopted as a means for sending the sheet to the apparatus, such as using a reciprocating pusher driven by a motor or a cylinder, or using a conveyor such as a belt or a roller. Moreover, you may pay out manually. In addition, feed rollers
36 is not always necessary, and the point is that the catalog C can be conveyed with its fore edge first.

In the above configuration, after the adhesive tape T cut to a predetermined length is fed out to the transport path of the catalog C by the second feeding belt 13 and the catalog C is transported by the booklet transport means 3, FIG. As shown in FIG. 7, the adhesive tape T is peeled off from the second feeding belt 13 and adheres to both front and back surfaces of the catalog C, thereby sealing the catalog C. The sealed catalog C is stacked on the collecting section 45 (the catalog C may be removed to the outside of the apparatus by a chute, or may be forcibly sent out by a conveyor).

As can be easily understood from FIGS. 6 and 7, since the adhesive tape T is simply stuck on the front and back surfaces of the catalog C in such a manner as to fall down, even if the catalog C is transported at a high speed, it can be stuck. There is no mounting failure,
Therefore, the efficiency of the sealing operation can be significantly improved. When the thin feeding belts 11 and 13 are used as the feeding means of the adhesive tape T as in the embodiment, there is an advantage that the adhesive tape T can be accurately fed with a simple structure using the adhesive force of the adhesive tape T.

The printing of the address (or the application of the address label) may be performed continuously to the sealing step. A single table 2 may be provided with a plurality of booklet conveying means and a tape feeding means (that is, a plurality of booklet conveying means and a plurality of booklet conveying means may be provided). In the above embodiment, the pressure-sensitive adhesive tape T was fed out along the longitudinal direction of the fore edge C1 in the catalog C. However, as shown in a modified example of FIG. Using a roll of dimensions
The adhesive tape T may be drawn out from a direction perpendicular to the fore edge C1 of the catalog C.

Although not shown, the adhesive tape T is fed out in a state of being laid down so that the adhesive surface thereof faces upward, and the catalog C is fed out in a state where the front edge thereof faces down. Is also good. Alternatively, the catalog C may be stopped to seal by moving the adhesive tape T, or the booklet and the adhesive tape may be sealed by moving both.

As shown in FIG. 9, this is another example of the adhesive tape T. In this example, the edge of the catalog C
The portion corresponding to C1 and the periphery thereof is a glueless portion T1 where no adhesive is applied, and two perforation lines M for tearing the glueless portion T1 are engraved. There is an advantage that can be opened.
