Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a bookbinding device that has a simple structure and can shorten bookbinding time.

[Prior art]

As a conventional bookbinding device, for example, the documents to be bound (
A tape-shaped binding member coated with a heat-melt adhesive of a size that corresponds to the thickness and length of the gold genuine article (hereinafter referred to as the bound article) is heated and pasted from the W part of the gold genuine article to the front and back covers (hereinafter referred to as both sides). Some books are bound by doing this.

This bookbinding device includes means for holding and raising/lowering a bound workpiece;
A guiding/supporting means for guiding and supporting all of the tape-like binding members in a predetermined position, a back heating means for heating and pasting the tape-like joining member on the back of the bound product, and a tape for each side of the bound product. It has side heating means for heating and bonding the bonding member.

In the above (1) configuration, the adhesive surface of the tape-like binding member, whose both ends in the width direction are held in tension by the guiding/supporting means, is brought into contact with the back surface of the bound product to guide and support the binding member. The binding member is separated from the means, and the entire back side of the separated binding member is heated and adhered by the back surface heating means, and the binding member is heated and adhered to both sides of the bound product by the side surface heating means to form a book binding.

However, in conventional bookbinding devices, the guide/support member that holds the tape-like binding member is driven 1) independently of the surface and side heating means and in accordance with the width of the tape-like binding member. As a result, the structure became complicated. Furthermore, since the guide support member is provided independently, there is a limit to the distance by which the back heating means and the side heating means can be brought close to each other, which reduces the degree of mutual utilization of heat and increases heat loss.

[Object and structure of the invention]

The present invention has been made in view of the above, and in order to simplify the structure, shorten the bookbinding time by shortening the warm-up time, and reduce heat loss, the present invention has been made in order to simplify the structure, shorten the bookbinding time by shortening the warm-up time, and reduce heat loss. To provide a bookbinding device that supports members.

The side heating means 8, 11 are directly or indirectly supported by a frame (not shown), and are driven by a drive means (not shown) such as a motor via power transmission means such as gears, cam arms, link mechanisms, etc. controlled. The back surface heating means 6 is fixed to a frame or the like. The setting table 4 is a plate-shaped body with a flat surface, and is configured to be able to reciprocate in the direction of the arrow just above the side heating means 8.11. It protrudes above the means 6 to support the bound workpiece on its upper surface, and prevents the bound workpiece 1 from being lowered onto the coupling member 5 on the upper surface of the back heating means by the club/bars 2 and 3 after the binding workpieces are aligned. It is configured to be retracted to the right in the drawing so as not to interfere with it. The clamper 2.3 includes an arm 20, a contact member 21 rotatably supported by a bottle 20m at the tip of the arm 20, and a rubber member 22 integrated with the tip surface of the contact member 21.

As the rubber member 2z, for example, a material having a large number of minute protrusions on the surface or other material having a large surface friction coefficient is used,
The retention of the bound product 1 is completely increased. The arm 2o is rotatably engaged with a power transmission means (not shown) via a pin 20b.

Fixed status! The LY side heating means 6 and the side heating means 8 and 11, which are configured to be able to reciprocate in the direction of the arrow, are made of metal materials such as aluminum alloy, which have excellent thermal conductivity and relatively low heat dissipation loss. It is preferable that the heating element 7

Inward protrusion amount of support 10.13! l is regulated by the inner stopper portion 8b and flb. The protrusion amount 11 is the distance 1. between the outer end surface of the support body 10.13 and the stopper portion 8esL1c. Set equal to . On the inner end of each support 10.13 is a tape-like connecting member 5.
Both edges in the width direction are supported. The operation of supplying the connecting member 5 onto the support 10.13 is carried out manually or mechanically.

This is a sectional view of A, and all types of coupling members 5 with different widths are prepared in advance so as to correspond to changes in the thickness of the bound product 1. Further, when the length of the bound product 1 changes, it is sufficient to cut the required length from the binding member wound into a roll according to each length for decorative use. For example, as the coupling member 5,
A flexible substrate 16, a relatively thin first heat-activated adhesive 17 (hereinafter referred to as the first adhesive) applied to the entire surface of one side of the substrate 16, and a widthwise center portion on the first adhesive 17 layer. A thick second heat-activated adhesive 18 (hereinafter referred to as second adhesive) applied over the entire length in the longitudinal direction is used. The first adhesive 17 has relatively high viscosity and low fluidity, and the second adhesive 18 has relatively low viscosity and high fluidity, and may have higher activity than the first adhesive. Use one that has a certain temperature. For example, the first adhesive 17i
When the activation temperature range is 121°C to 176°C, the second adhesive 1B has an active temperature of 176°C to 232°C.

Incidentally, instead of raising and lowering the bound product, the heating member may be entirely raised and lowered.

In the above configuration, to explain the bookbinding process, what is the bound book held between the cranium nuts 2 and 3 as shown in Figure 1?

As shown in FIG. 5(a), the R-surface heating element 6 is in a heating state.
The center portion of the binding member 5 is pressed against the upper surface to bring the molten second adhesive 18 into close contact with the back surface 1c of the bound article 1. At this time,
Both edges in the width direction of the coupling member 50 are hooked onto the inner edge of the support body 10.13 and bent upward. The side heating means 8.11 only begin to move inward after the state shown in FIG. 5(a). When the side heating means 8.11 moves inward, the support member 10.13 also moves in synchronism with this,
While raising both ends of the connecting member 5 in the width direction upward, the movement is continued until the tip thereof is completely stopped by the side surfaces 1a and lb of the binding material. Even after the support member 10.13 has completely stopped moving, the side heating means 8.15 continues to move inward against the spring 14.15, and each of the joining members 5 raised by the support member 10.13 Edge Rk side of bound product 1m + 1b with inner end surface in heated state

In the bookbinding apparatus of the present invention, the tape-like binding member is guided and supported by the supporting member incorporated in the side heating means, thereby eliminating the need to provide a separate guiding and supporting means, resulting in a simple structure. It is possible to achieve miniaturization, compactness, and cost reduction. In addition, since the side heating means and back heating means (kW) can be placed close to each other in the first JIJJ process, it reduces heat loss and reduces the waiting time (warm 7, 1 hour) until the bookbinding ITf function is activated after the power is turned on. ) can be achieved. Furthermore, since there is no independent means for guiding and supporting the connecting members, unnecessary operating time is eliminated, and the time required for making one product can be shortened.

Furthermore, there is no need for a mechanism for adjusting the spacing between the supporting members in response to variations in the tape width of the joint.

〔Effect of the invention〕

As described above, according to the bookbinding device Beni of the present invention, since the tape-like binding member is entirely supported by the side heating means, the configuration is simplified, the bookbinding time is shortened by shortening the warm-up time, and the heat loss is reduced. A reduction of t- can be achieved.
