Description

DETAILED DESCRIPTION OF THE INVENTION A bookbinding apparatus is capable of positioning a book at a current position (having a predetermined tolerance; the same applies hereinafter) without depending on the strength of the bookbinding device.

As a conventional bookbinding device, for example, there is one in which a booklet is placed on a booklet at a predetermined setting position, and a thermometer or adhesive tape 1v is pasted from the back of the booklet to the cover and spine.

Figure 1 Rei. (The figure shows this bookbinding device and places the bound book l.)
The bookrest 2 is supported by a spring 3, and a taran 14 is provided to hold the bound workpiece 1 between the openings formed in the guide plate 5. There is.

A tape guide 7 is located below the guide plate 5 to guide and support a mote 1 or an adhesive chip 16 (hereinafter referred to as "Chi 1").
'F7jr A front press 8 and a rear press 8b that move slowly in the horizontal direction are provided.

With the above configuration Ki, from above the guide 5 to between the
Insert the real item 1 and place the bound item 1 on top of the puttaresu) 2,
The taran 14 holds the bound object 1 from both balls. The sandwiched workpiece 1 is moved upwardly by the tarun 74 to a level above where the chi 76 is located, and the chi 16 is inserted into the tape guide 7 and supported. The front brace 8a moves horizontally under the insertion support of the chi 16, and when it stops below the back surface of the chi 16, the crank 14 descends, and the bound workpiece 1 is pressed by the chi 76 on the front brace 8a, and the workpiece 1 is pressed against the chi 76 on the front brace 8a. !
The chi 76 is glued to the back of J1 (if the tape 6 is thermo tape, the front breath 81 and rear breath 8b
They are thermally fused by using a heater brace, and in the case of an adhesive chip 7, they are bonded simply by pressing the -7 brace 8a #8b.

same as below). Next, after the front brace 8a returns to its original position, the binding object 1 is lowered by the downward movement of the flange 4, and when the binding object 1 presses the bookrest 2 and is balanced with the elastic force of the spring 30, the clamp 4 is Stop. continue,
The front breather 8 heat and the rear breather 8b press the tape 6 located from the back of the Biyosho genuine article 1 to the cover and spine K! Ill, and the pasting work of Qi 16 is completed.

However, in conventional bookbinding devices, the thickness of the bound book 1,
Or, based on the material, the bookrest 2 is supported by the spring 3 which has a single spring charge regardless of the stiffness K1m, so if the spring constant is increased, the bound book 1 is thin and weak. Since the spring 3V cannot be displaced by a predetermined amount, there is a possibility that the product cannot be lowered to the 1V power setting position.

The present invention has been made in view of the above-mentioned Kflk, and does not depend on the thickness of the bound product or the strength of the strain based on the material.
111 In order to position the bookrest at the set position, the bookrest is supported by a spring with a spring constant that displaces the bookrest by a predetermined amount when a bound booklet with a predetermined stiffness presses against the bookrest. The present invention provides a bookbinding device provided with a displacement stripe bar that prevents the nail from being bent when the nail is displaced by more than the predetermined amount.

The bookbinding apparatus according to the present invention will be explained in detail below.

2nd Wabi), (Dark mark indicates one embodiment of the present invention and only the essential parts are shown, 11th mark, (Parts common to 轡 are omitted)
The bookrest 2 is supported by a spring 3 having a spring constant capable of displacing a predetermined amount and positioning the bound workpiece 1 at a set position even when the thin and weak bound workpiece 1 is lowered. A displacement preventing member 1O is fixed to, for example, by a screw connection. The spiritual position prevention member IO is connected to the bookrest 2 between the bracket member 110 retaining surface 11a and the bracket member 110 that prevents its descent when the Pk foot is lowered.
It constitutes a displacement prevention stopper that prevents displacement of more than a predetermined amount, and the bookrests 2 and 1 racket member 11 allow relative displacement by the guide member 2a (bookrest 2KIi!i'1 foot) and guide slit 1lbK. While being relevant.

In the above configuration, since the spring 3 has a small spring constant so that the thin and weakly stiff bound workpiece 1 descends by a predetermined amount, the weakly stiff bound workpiece 1 falls. By balancing the elastic force of spring 3 when descending, the wrinkles genuine 1 can be made into a shark? mK positioning is possible. In addition, when the stiff binding material 1 descends and the crack 3 attempts to displace more than a predetermined amount, the 4 displacement preventing member 10 and the retaining member 11
11atI) The k-made article 1v can be positioned in the foot position where displacement is prevented by contact. Therefore, it is possible to apply an appropriate IK sting to the manufactured product. Note that the configuration of the displacement stopper is not limited to that shown in the drawings; for example, it may be provided on the member 1 between the threads of the spring 3 to prevent it from shrinking more than that.

As explained above, according to the bookbinding unit* of the present invention, the bookrest is supported by a spring having a spring constant that displaces a predetermined amount when the bookrest is pressed with a bound product having a predetermined stiffness, and Since a displacement stopper is provided to prevent the spring from being displaced by more than the predetermined amount, the workpiece can be positioned at a set position based on the thickness or material of the workpiece, regardless of the strength of the strainer. can.

Claims (1)

[Claims] In a bookbinding device in which a bookbinding tape is applied from the back of a bound book to a cover and spine K on a bookrest elastically supported by a spring K, the spring has a predetermined stiffness. The bookbinding device has a spring constant that causes the bookrest to be displaced by a predetermined amount when the bookrest is pressed, and the bookrest has a displacement prevention stopper that stops the displacement v#N when the bookrest is displaced by the predetermined amount or more. &41
