DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spine attaching apparatus for attaching a spine to the back of a plurality of bound documents.

[0002]

2. Description of the Related Art Heretofore, a spine has been pasted on a plurality of documents which have been stapled in advance and stapled for the purpose of improving the appearance and reinforcing the binding.

As shown in FIG. 8, an attaching device 1 (see Japanese Utility Model Publication No. 47-23208), which is a main part of a spine attaching device, is provided.
Guide plate 3 from which adhesive tape 2 having adhesiveness on one side is drawn out
And a pair of rollers 4 arranged at predetermined positions at an interval vertically. The adhesive tape 2 is fixed to the guide plate 3 via a jig (not shown) with the adhesive surface facing outward, and the lower edge of the adhesive tape 2 is slidably provided below the guide plate 3. It is mounted on a slightly laterally projecting upper surface of the platen 3a. The adhesive tape 2 is cut to a required length and sent to the front of the pair of rollers 4 as the guide plate 3 and the support plate base 3a move. The document 5 is set with its back facing the center of the adhesive tape 2. Next, as shown in FIG. 9, the guide plate 3 is
Is pressed against the adhesive surface of the adhesive tape 2 while the adhesive tape 2 is stopped in front of the roller 4 so that the adhesive tape 2
(See FIG. 9A). Next, when the guide plate 3 is retracted and the document 5 is moved to the roller side, both edges of the adhesive tape 2 are bent by the roller 4 and attached to the cover of the document 5 (see FIG. 9B). Then, by pulling back the document 5, the document 5 having the spine is obtained (see FIG. 9C).

[0004]

In the above conventional example,
The adhesive tape 2 has a tip fixed to the guide plate 3 and a lower edge placed on the support plate base 3a, and is held in a state where the non-adhesive surface of the adhesive tape 2 is stuck on the plane of the guide plate 3. Therefore, if the lower edge of the adhesive tape 2 gradually bends due to the warp of the adhesive tape 2 or the like, the position of the adhesive tape 2 on the support plate base 3a may shift, and the adhesive tape 2 is maintained at a predetermined position in a plane. It is difficult to hold for a certain period of time.

[0005] For this reason, when the adhesive tape 2 shifted in position is brought into contact with the back of the document 5, wrinkles may be generated on both edges of the attached adhesive tape 2. Since the spine of the tape 2 causes the spine to be attached diagonally to the document 5, the appearance is poor, and if the adhesive tape 2 is extremely bent, the adhesive tape 2 comes off the support plate 3a and becomes oblique and adheres to the document 5. There is a problem that the back is exposed.

The present invention relates to an apparatus for sticking an adhesive tape to a document by pressing with a roller, and a spine cover attaching apparatus having a support member capable of holding the adhesive tape in a predetermined position in front of the roller while maintaining its shape. The purpose is to provide.

[0008]

Since the present invention is constructed as described above, the adhesive tape sent out from the sending device is bent in a V-shape through the guide member, and the V-shaped guide member having the shape and extending along the extension is attached. It can be pushed to the position. Also,
Since the adhesive tape is bent in a substantially V-shape, a restoring force of the adhesive tape itself to return to a flat surface acts, and both edges of the adhesive tape press against the flange. Also, the back side of the adhesive surface of both edges is similarly pressed against the sliding contact surface of the guide plate. Therefore,
The adhesive tape is fixed at a predetermined position unless an external force is applied to the adhesive tape. In addition, the gaps between the pair of positioning plates that are close to each other are aligned with the center of the V-shaped bent adhesive tape, and each positioning plate guides the document and the back surface is located at the center of the adhesive tape. Work like that.

A bent portion 39d for holding both edges of the adhesive tape 2 is formed on both edges of the guide member 39. A notch 39 is provided at the tip 39b on the exit side of the guide member 39.
e is formed, and a pushing piece 391 for pushing the cut rear end of the adhesive tape 2 is provided so as to be able to enter the cut groove 39e. The pushing piece 391 is actuated by the cam mechanism in the cam chamber,
It has a function of pushing out a tape bent in a V shape to a predetermined position. The bending roller group 40 and the supporting roller group
41 is connected to the motor 32 via a large gear 42. On the extension of the guide member 39, a V-shaped guide member 18 is provided so as to extend beyond a passage hole (not shown) formed in the support member 14.

Next, the operation of the present device 6 for feeding the adhesive tape 2 to the V-shaped guide member 18 will be described. First, the pair of feed rollers 35 rotate via the clutch gear 37 by the drive of the motor 32, and the bending roller group 40 and the support roller group 41 disposed on the guide member 39 rotate via the large gear 42. As a result, the adhesive tape 2 passes through the supply port, is held by the bent portion 39d of the guide member 39 with the adhesive surface facing outward, and is moved while being sandwiched between the bending roller group 40 and the support roller group 41. From the distal end portion 39b of the guide member 39, the adhesive tape 2 bent in a V-shape with the adhesive surface inside is sent out.
At this time, the pushing piece 391 that enters the cut groove 39e is at a position where the movement of the adhesive tape 2 is not hindered. The adhesive tape 2 bent in a V-shape has increased rigidity of the tape itself, and is pushed into the V-shaped guide member 18 by a feed force due to rotation of the bending roller group 40 and the support roller group 41.

When the adhesive tape 2 having a predetermined length is extruded into the V-shaped guide member 18, the tip of the adhesive tape 2 is detected by the sensor 25 (FIG. 3), and the motor 32 is stopped to stop feeding the tape. In accordance with this timing, the cutting blade is moved by the cam mechanism to cut the adhesive tape 2 at the supply port position. Next, the clutch gear 37 is pushed down by the cam mechanism to interrupt the transmission of rotation, and the sending device 36 is stopped. By driving the motor 32 in this state, the bending roller group
The 40 and the support roller group 41 rotate, and the adhesive tape 2 cut to a predetermined length is further extruded. Then, the adhesive tape 2 bent in this manner is sent out until the rear end portion comes off the bending roller group 40. At the time when the rear end of the adhesive tape 2 comes off the bending roller group 40, a pushing piece is pushed by a cam mechanism.
By actuating 391, the adhesive tape 2 can be pushed out to a predetermined position of the V-shaped guide member 18. Further, the motor 32 is stopped.

Next, the operation of the adhesive tape 2 arranged on the V-shaped guide member 18 will be described. 1 and 2
As shown in the figure, the adhesive tape 2 bent in a V-shape is inserted between the positioning plate 23 and the sliding contact surface 24a of the guide plate 24 with both edges thereof aligned. The adhesive tape 2 is inserted while being bent in a V-shape, and both ends of the adhesive tape 2 abut against the flange 22 due to the restoring force due to the bending, and the non-adhesive surfaces of both edges of the adhesive tape 2 slide in contact with the sliding surface 24a. Press against Thereby, the V-shape of the adhesive tape 2 is maintained, and a gap is formed between the positioning plate 23 and the adhesive tape 2, thereby preventing the adhesive tape 2 from being stuck to the positioning plate 23. In addition, since the upper roller and the upper roller of the pair of feed rollers 16, the positioning plate 23, and the pressure roller 17 are movable vertically,
Regardless of the thickness of the document, the center is aligned and the adhesive tape 2
With the center in the width direction.

In this state, the motor 19 is driven and the feed roller 16 and the pressure roller 17 are rotated. Next, the document 5 is placed on the placing table 7 and the back of the document 5 is
The feed roller 16 is fed from the insertion port 12 to the feed roller 16 along the knob 10 so as to be substantially parallel to 16. The position of knob 10 is
The length of the adhesive tape 2 is automatically determined by first setting the size according to the size of the document 5. Then, the back of the fed document 5 is guided and positioned in a V-shape formed by the positioning plate 23, passes through, and pushes the V-shaped bottom of the adhesive tape 2 held by the V-shaped guide member 18. While being pressed into the pressure roller 17 and pressed. In the pressure bonding by the pressure roller 17, the positional relationship between the adhesive tape 2 and the positioning plate 23 is aligned at the center and the depth direction of the document 5 is also uniform, so that the center of the adhesive tape 2 and the back of the document 5 are It will be pasted in conformity. Further, since the position and the shape are maintained by the restoring force until the adhesive tape 2 is stuck to the document 5, the force of the pressure roller 17 is uniformly applied and no wrinkles or the like occur during the sticking.

Further, when the document 5 is fed in, the back portion of the document 5 is detected by the detection sensor 21 (FIG. 6), whereby the motor 19 rotates in the reverse direction, and the document 5 moves in the reverse direction and is inserted. It is carried out from the mouth 12.

[0020]

As described above in detail, according to the present invention, the pressure-sensitive adhesive tape itself can be made rigid by bending the pressure-sensitive adhesive tape having a predetermined length into a V-shape. Can be installed at a predetermined position of the V-shaped guide member facing the. In addition, it is possible to wait in a state where the center of the adhesive tape is aligned with the back position of the document. This facilitates the alignment between the adhesive tape and the document, and allows the adhesive tape to be adhered to the document with good appearance.
