According to the invention, the adhesive tape fed into the guide rail is supplied over the guide plate, and the tip of the guide plate is engaged with the back surface of the adhesive tape. Become. Then, after the tape is fed by a predetermined length, the adhesive tape adheres to the tip of the cutter blade when the cutter returns after cutting the adhesive tape, so the adhesive tape in the guide rail is moved in the opposite direction to the feed. Force to move works. However, since the front end of the guide plate is engaged with the back surface of the adhesive tape, the guide plate stretches in the opposite direction to prevent the movement of the adhesive tape. Moreover, the guide plate cannot enter the opening due to the obstruction of the adhesive tape. Therefore, since the adhesive tape does not move in the reverse direction and does not shift, the adhesive tape in the housing portion always maintains an accurate posture even when cut.

Further, when the adhesive tape once fed is pulled out from the guide rail, the guide plate is also subjected to the check action. However, when the adhesive tape is pulled out with a stronger force, the guide plate is bent to the opposite side and passes through the opening, so that the adhesive tape passes through the opening. The adhesive tape is pulled out because it is inclined in the forward direction with respect to the pulling-out direction. Thereafter, the guide plate returns to the original position.

Therefore, according to the first aspect of the present invention, the bookbinding adhesive tape is guided so as not to move during cutting, so that a good bookbinding finish is always possible.

According to the invention of claim 2, since the side end of the adhesive tape is guided by the guide means, the adhesive tape does not move at the time of cutting.

Therefore, according to the above invention, the adhesive tape in the storage section can always maintain an accurate posture even when cut.

[0012]

FIG. 1 shows a main part of a bookbinding apparatus. This bookbinding apparatus is provided with a holder 3 for holding an adhesive tape 2 for bookbinding and a cutter 4 for the adhesive tape 2 on one side of a base 1.
Between a pair of side walls 1a formed on the other side of the base 1, a table 5 on which bookbinding paper a is placed, a guide rail 6 for receiving the adhesive tape 2, and pressing the adhesive tape 2 onto the binding paper a. And the adhesive tape 2 by moving the guide rail 6 to bind the bookbinding paper a.
(The stapling is performed on the binding side) and a rail drive mechanism 8 to be attached to the one side.

Reference numeral 9 denotes a mechanism for feeding the adhesive tape 2;
Reference numeral 0 denotes an auxiliary roller, and reference numeral 11 denotes a feed roller for the adhesive tape 2. Reference numeral 12 denotes a tape guide. Reference numeral 13 denotes a gauge 13 movably provided on the table in accordance with the size of the bookbinding paper a. At the upper end of the gauge 13, a sensor 14 for detecting the tip of the adhesive tape 2 is attached.

As shown in FIG. 2, the guide rail 6 has a storage portion 15 between the upper rail 6a and the lower rail 6b for accommodating one side of the adhesive tape 2 in a protruding state. Are formed, and side plates 16 that are bent downward from both ends are formed. The storage width of the storage portion 15 of the guide rail 6 is about 1 width of the width of the adhesive tape 2.
/ 2. Therefore, one side of the adhesive tape 2 is stored in the storage section 15, and the other side protrudes from the storage section 15.

Next, a release paper 17 is adhered to the entire back surface of the adhesive tape 2.
It is divided into two in the longitudinal direction with a width of 2. Therefore, when the adhesive roller 2 is fed into the guide rail 6 via the tape guide 12 by a feed mechanism (not shown), the feed roller 11 transfers a half 17a of the release paper 17 of the adhesive tape 2 to the feed roller 11 via the auxiliary roller. The adhesive tape 2 is fed into the guide rail 6 via the tape guide portion 12 while the release paper 17a is peeled off from the adhesive tape 2 as shown in FIG. Since the other half of the adhesive tape 2 remains in the guide rail 6, it does not adhere to the guide rail 6.

When the adhesive tape 2 is fed into the guide rail 6 by a feed mechanism, the adhesive tape 2
The cutter 4 is driven when the sensor 14 detects that the sheet has been fed by a predetermined length determined by the gauge 13, and the adhesive on the cutting table 18 provided between the tape guide portion 12 and the guide rail 6. The tape 2 is cut.

Next, as shown in FIG. 2, a clamping means 7 is disposed above the protruding portion 2a of the adhesive tape 2 in the guide rail 6. This clamping means 7
Presses the protruding portion 2a of the adhesive tape 2 against the upper surface of one side of the binding paper a on the binding side, and is operatively connected to a clamp drive mechanism (not shown).

Further, the rail drive mechanism 8 allows two guide shafts 20 to pass through both side plates 16 of the guide rail 6, and connects both ends of the guide shaft 20 to both side walls 1 of the base 1.
The two L-shaped holes 21 that are bent at “a” are made to penetrate and are linked to the drive link 22. Then, by driving the drive link 22 by a drive unit (not shown), as shown in FIGS.
0 moves vertically and horizontally along the L-shaped hole 21;
Following this, the guide rail 6 is also moved in the same direction.

In the above construction, the adhesive tape 2 is fed into the guide rail 6 by the feed mechanism, cut into a predetermined length, and then the rail drive mechanism 8 is operated to move the guide rail 6 downward, thereby causing the adhesive tape 2 to move downward. 2 protruding part 2
The backside adhesive layer of the adhesive tape a is brought into contact with the upper surface of the one side of the bookbinding paper a (see FIG. 3), and at the same time, the protruding portion 2a of the adhesive tape 2 is pressed onto the bookbinding paper a by the clamping means 7 so that the adhesive tape 2 Is adhered to the upper surface of the binding paper a, and further moved along the one side end surface to a lower moving end to adhere the adhesive tape 2 to the side end surface (see FIG. 4).
Subsequently, the adhesive tape 2 is continuously moved along the bottom surface of the bookbinding paper a, and is adhered to the bottom surface by squeezing the adhesive tape 2 at the convex portion 23 at the side end of the upper rail 6a (see FIG. 5). Then, the adhesive tape 2 is attached to the binding side of the binding paper a to complete the binding.

After the adhesive tape 2 is brought into contact with the surface of the bookbinding paper a, when the guide rail 6 moves downward, the central portion of the adhesive tape 2 in the storage section 15 is bent at substantially a right angle, and a, but the release paper 17 does not bend, but finally comes off when the guide rail 6 moves horizontally along the bottom surface of the bookbinding paper a (see FIGS. 4 and 5). .

The bookbinding apparatus includes an adhesive tape 2
Is provided. As shown in FIGS. 7A and 7B, this guide mechanism forms a guide plate 25 projecting obliquely upward by bending a metal spring plate 24 fixed to a lower portion of the guide rail 6 near the adhesive tape introduction port. The guide plate 25 penetrates through the opening 26 of the lower rail 6b and enters the storage section 15, and is disposed so as to diagonally cross the storage section 15 of the guide rail 6 along the feed direction of the adhesive tape 2. The guide plate 25 is configured so as to be capable of being bent to the opposite side through an opening 27 formed in the upper rail 6a of the guide rail 6 so as to be bent to the opposite side.

The guide plate may be provided from the top to the bottom. In this case, the tip of the guide plate is formed so as to face an opening formed in the lower rail. Further, a configuration in which a recess is formed instead of the opening may be used.

According to the guide mechanism, as shown in FIGS. 8A and 8B, the adhesive tape 2 fed into the guide rail 6 by the feed mechanism is connected to the guide plate 25 made of metal spring.
And the leading end of the guide plate 25 is engaged with the back surface of the adhesive tape 2. Then, after being fed by a predetermined length, the cutter 4 operates and the cutter 4
Moves down to cut the adhesive tape 2, and then returns to the original position again. At the time of upward movement, the tip of the blade of the cutter 4 adheres to the adhesive layer of the adhesive tape 2, so that a force acts to move the adhesive tape 2 in the storage section 15 in a direction opposite to the feed direction. However, since the front end of the guide plate 25 is engaged with the back surface of the adhesive tape 2, the guide plate 25 stretches in the opposite direction to prevent the movement of the adhesive tape 2. Moreover, the guide plate 25 cannot enter the opening 27 of the upper rail 6a because the adhesive tape 2 hinders the guide plate 25. Therefore, the adhesive tape 2
Does not move in the opposite direction, resulting in displacement.
The accurate posture of the adhesive tape 2 in the storage section 15 is always maintained even by cutting.

When the adhesive tape 2 is fed, the adhesive tape 2 engages with the guide plate 25 of the guide plate 25.
At this time, since the angle of the guide plate 25 is in the forward direction with respect to the feeding direction of the adhesive tape 2, the movement of the adhesive tape 2 is allowed.

Further, when the remaining amount of the adhesive tape 2 is small and is not enough to spell the bookbinding paper a, the adhesive tape 2 once fed is pulled out from the guide rail 6. In this case as well, the guide plate 25 is subjected to the check action. However, when the guide plate 25 is pulled out with a stronger force, the guide plate 25 is bent to the opposite side as shown in FIGS. The adhesive tape 2 passes through 27 and is inclined in the forward direction with respect to the pull-out direction of the adhesive tape 2, so that the adhesive tape 2 is pulled out. Thereafter, the guide plate 25 returns to the original position.

As shown in FIGS. 10 and 11, the guide mechanism of the adhesive tape 2 is provided at the bottom of the clamping means 7a at the protrusion 2a of the adhesive tape 2 from the guide rail 6.
May be provided with a guide means 28 which engages with the side edge of. Two openings 30 are formed in the bottom plate 29 of the clamping means 7 a, and upstanding pieces 31 are cut and raised inside the openings 30. The guide means 28 is constituted by a curved metal spring plate, and both sides of the guide means 28 pass through the opening 30 and bent portions 32 at both ends.
Are engaged with the standing pieces 31. Further, the curved portion of the guide means 28 is arranged such that its side end surface is engaged with the side end portion of the protrusion 2a of the adhesive tape 2. 33 is a compression spring. At the time of clamping, both ends of the guide means 28 are folded.
The bent portion 32 escapes upward and the adhesive tape 2
The curved part that guides the side edge of the projection part should be deformed flat
The guide means 28 cooperates with the clamp means 7a to
Acts as a pump.

According to the above configuration, one end of the adhesive tape 2 is guided by the guide means 28, so that the adhesive tape 2 does not move obliquely during cutting. Therefore, the adhesive tape 2 in the storage section 15 is always maintained in an accurate posture even when cut.
