Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of I-Kyoku-L] The present invention relates to an automatic bookbinding time extending device in a bookbinding machine.

[Prior art]

In general offices and companies, for example, copies are made using a copying machine, and the resulting copies are sometimes stitched together to form a book. For this reason, bookbinding machines that can easily and automatically bind sheets of paper are widely used.

FIG. 1 schematically shows an example of such a conventional bookbinding machine. In this bookbinding machine, a pair of heating plates 2 are provided above a paper mounting table 1 so as to be movable in the horizontal direction. A pair of guide plates 3 are provided above the heating plate 2 so as to be movable in the horizontal direction. Guide grooves 4 are formed in mutually opposing end surfaces of the pair of guide plates 3. A pair of clamp plates 5 are provided on one side of the guide plate 3 so as to be movable in the horizontal and vertical directions. The driving force of a motor 6 (not shown in FIG. 2) is transmitted to the heating plate 2 and the clamp plate 5 via a cam mechanism (not shown), so that the heating plate 2 and the clamp plate 5 are moved in a predetermined manner. The guide plate 3 is configured so that the driving force of a not-shown pusher motor is transmitted to the guide plate 3 through a not-small-figure structure, etc., and the guide plate 3 is moved in a predetermined manner.

When binding a book using this bookbinding machine, first, the spines of an appropriate number of sheets of paper 11 are placed on the paper mounting table 11-4. 7 Next, press the start button 12, the motor 6 will start driving,
The shaft 13 shown in FIG. 3 begins to rotate in the direction of the arrow. When the shaft 13 rotates slightly in the direction of the arrow from the initial position shown in FIG. 3, the microphone 1j switch 15 for holding the motor drive opens. As a result, even if the start button 12 returns to its original state, the motor 6 continues to drive.

As the motor 6 is driven, the pair of clamp plates 5 approach 77 and clamp the paper 11 from both sides, as shown in FIG. Thereafter, as shown in FIG. 5, the phantom clamp plates 5 are raised by 1 as appropriate, and the paper 11 is lifted to one side relative to the guide plate 3. Next, by driving the motor 6, one of the pair of heating plates 2 is directed toward the other.
It moves and is positioned below the paper 11.

The thickness of the paper 11 is detected by two microswitches 16 and 17 that detect the clamping position of the clamp plate 5. That is, when the thickness of the paper 11 is less than dl (for example, 1 cm), only one microswitch 16 switches from contact a to contact d, d, to d.
2 (for example, 2 cm), only the other microswitch 17 switches from contact a to contact
In this case, both microswitches 16 and 17 are not switched.

When the paper 11i is lifted above the kite board 3, the sub-motor starts to drive at this timing.Then, the pair of guide plates 3 approach each other and move according to the thickness of the paper 11 as shown in FIG. This stopping is controlled based on the detection results by two microswitches 16 and 17 that detect the clamping position of the clamp plate 5.

When the shaft 13 reaches a position rotated approximately 120° in the direction of the arrow from the initial position shown in FIG.
Due to the action of 4, M? The microphone for inserting the streamer tape [The switch 18 switches from contact A to contact S. Then, the motor 6 stops driving, and a mode for inserting the back reinforcement tape 19 as shown in FIG. It has a structure in which the adhesive 23 is applied relatively thinly on both sides a. In this example, f! Types of tape I] 1 are available in which the widths of the contact agent 22 at the center are dl, d2, and d3 (for example, 3 cm).

At the time ゛c' when the microphone 1j switch 18 for inserting the backing tape is switched in this way, the paper +

It has already been detected by
111 is less than or equal to d, the first
When the lamp 24 is fishing, the second lamp 25 lights up when d+~(12), and the third lamp 26 lights up when d+~(12). The mepelator selects the back beam tape 19 according to the lamp used for fishing.For example, suppose that the second lamp 25 is turned on.

In this case, a piece of tape 19 is selected in which the width of the adhesive 22 at the center is approximately the same as the maximum width d2 of the paper 11 at this time. The operator inserts the backing tape 19 selected in this way into the guide groove 4 of the pair of guide plates 3 as shown in FIG.
It should be located below.

After inserting the back tape 19 in this way, do not press the tape set end button 27. Then, the motor resumes driving and the shaft 13 begins to rotate in the direction of the arrow. When the shaft 13 rotates slightly in the same direction, the cam plate 14
Due to the action of , the microswitch 18 is brought into contact and is switched to contact a.

As a result, even if the tape set end button 27 returns to its original state, the motor 6 continues to be driven.

As the motor 6 is driven again, the pair of clamp plates 5 are lowered together, and the back of the paper 11 presses the center of the spine tape 19 against the upper surface of one of the heating plates 2, as shown in FIG. Then, the adhesive 22 at the center of the backing tape l1 is melted and attached to the paper 110) 11T'. On the other hand-

), and the pair of guide plates :) are separated by -14 degrees and returned to their initial positions.

- When a certain period of time has elapsed after the pair of clamp plates 5 reached the lower limit position at this time, the pair of clamp plates 5 are both raised by the drive of the motor 6, and the paper 11 is lifted up by the spine attached to its back. Hold the tape 19 on three sides from the guide plate 3. At the same time, one heating plate 2 is returned to its initial position by driving the motor 6. Next motor 6
The pair of clamp plates 5 are lowered together by the drive of n47.
As shown in the figure, use the back of the paper 11 to push the center of the tape 19 onto the lx surface of the paper mounting table l. Next, as the motor 6 is driven, the pair of heating plates 2 rapidly approach each other, and their mutually opposing end surfaces push both sides of the one-sided tape 19 onto both sides of the back of the paper 11. Then, the adhesive 23 on both sides of the backing tape 19 is melted, and the paper 11 is
441 on both sides of the back.

When a certain period of time has elapsed after the pair of heating plates 2 reached the current approach limit position, both the heating plates 2 and the clamp plate 5 are returned to their initial positions by driving the motor 6. Thereafter, when the shirt 13 rotates 360 degrees from the initial position and reaches the original initial position, the microswitch 15 for holding the motor drive is opened by the action of the cam plate 14. Then, the motor 6 stops driving and enters the stop mode.

The melted adhesives 22 and 23 harden naturally, thus completing the bookbinding.

By the way, in such a conventional bookbinding machine, for example, it takes about 10 seconds for the sheet 13 to reach a position rotated approximately 120 degrees in the direction of the arrow from its initial position, and then rotated further in the direction of the arrow from the same position. 2 to return to initial position
It is designed to take about 0 seconds. However, in such a bookbinding machine, the back of the paper 11 is pressed against one heating plate 2 through the center of the back tape 19, regardless of the thickness of the paper 11 set and the type of back tape 19. The time required for the heating process is set to be a certain period of time. If the time required for this heating-1: is relatively long, the paper 11 will be heated too much if a small backing tape 19 is used at a temperature of 17 or less.
This wastes energy and time, and also causes the adhesive to melt and run off, resulting in poor binding. On the other hand, if the time required for the heating process is relatively short, if the thickness of the paper 11 is d2 or more and a large backing tape 19 is used, the adhesive cannot be properly melted and binding defects may occur. It can also be a cause of occurrence.

Therefore, in the past, the time required for heating 1-2 was often adjusted to the intermediate back tape 19, and in the case of small and human back tape 19, the above-mentioned disadvantages were likely to occur. Ta. .

So, the conventional bookbinding machine requires 11. Some devices allow you to adjust the distance by turning a dial in advance. However, with such a bookbinding machine, it is troublesome to operate the dial by turning the dial 4'. In addition, if the user forgets to perform an operation or erroneously performs an operation which causes the temperature to drop to °C, defective bookbinding may occur.

[Purpose of the invention]

The present invention has been made in view of these circumstances, and is an automatic bookbinding time extension that can automatically extend the time required for the heating process as described above by a predetermined time only when the largest binding tape is used. The purpose is to provide equipment.

[Structure of the invention]

In the present invention, a detection means is provided to detect when the thickness of the set paper is equal to or more than a predetermined thickness, and when the detection means is activated, the time required for the heating process as described above is automatically extended by the means. It is designed to extend for a predetermined period of time.

Zunawara In the present invention, the normal time required for the heating process as described above is adjusted to a tape other than the maximum backrest tape.
The time required for heating is automatically extended only when using the largest tape.

〔Example〕

The present invention will be described in detail below with reference to Examples.

Figure 1], J3 and Figure 1 (Figure 1) show the main parts of a bookbinding machine to which an embodiment of the present invention is applied.

In these figures, the same parts as in FIG. 2 and FIG.

Further, in explaining this embodiment, reference may be made to FIG. 1 and FIGS. 4 to 8 as appropriate.

In this bookbinding machine, the clamp plate 5's clamp (11th position: ξ is detected by the three microphones 1) switch 16, 17 and ; (1).
l If it is below, the first microphone “1 switch 16
When dl~(12, only the second microphone eco switch 17 is closed, and when d2~d3, only the third microphone switch 31 is closed. I started to do this.

Now, 1゛1'' is placed on the second bookbinding (number 0) paper holder 1.
Assume that 2 to (1) sheets of paper 11 (7) + 1 yen are placed and the start button 12 is pressed (FIG. 11a). Then, the motor () starts driving (Fig.
When the clamp plates 5 are closed, the pair of clamp plates 5 approach each other to clamp the paper 11 from both sides.

After this, the phantom clamp plates 5 rise together and lift the paper 11. At this time, since the thickness of the paper 11 is d2 to d3, the first to third microswitches [6, 17, 3
1, only the third microswitch 31 is opened (
Figure 11d).

When the shirt) 13 reaches a position rotated approximately 120 degrees in the direction of the arrow from the initial position shown in FIG. 10, the cam plate 14
As a result of this action, the microswitch 18 for inserting the backing tape switches from contact a to contact i (Fig. 11e).

Then, the motor 6 stops driving (FIG. 11b), and a mode is entered for inserting the spine tape 19. Also at this time, the third
Since only the microphone 1] switch 31 is closed, the third lamp 26 is stippled (I'l1, Figure f), which causes the burr tape 19 to adhere at its center.
The width of 2 is the maximum thickness d of the paper 11 at this time.

You will choose something almost the same. Furthermore, the first relay 32 provided in parallel with the third lamp 26 is activated (FIG. 1Ig), and its relay contact 33 is closed.

Next, insert the tape 19 of the selected +4 predetermined number and then press the tape set end Y button 27 (Fig. 11 II). 4 is activated (FIG. 11I), its relay contact is opened. This causes the second relay 34 to be self-retained. Also, the motor 6 resumes driving (FIG. 11B), and the shaft 13 begins to rotate again in the direction of the arrow.When the shaft 13 rotates slightly in the same direction, the force l.
Due to the action of the plate 14, the microswitch 18 is brought into contact l)
It switches from to contact a (Fig. 11e). This causes the third lamp 2 (i to go out), and the first lamp to turn off.
The relay 32 becomes inactive (g in the figure).

Due to the 1rJ movement of the motor 6, the clamp plate 5 of document 1 is lowered together, and the l of document 11 is lowered as shown in FIG.
"J' section - C stomach: Press the center part of the ?bar tape 19 against the two sides of one heating plate 2. As a result, melting of the adhesive 22 by heating is started. After this, when the shaft 13 is rotated to some extent in the direction of the arrow by the drive of the motor 6,
By the action of the cam plate 14, the microswitch 36 for extending the heating time is closed (FIG. 11j). Then motor 6

1k), the timer contact 38 is opened. Therefore, the power to the motor 6 is cut off, and its driving is stopped again (FIG. 11b). By stopping the motor 6, the heating time at this time will be extended.

When the time preset in the timer 37 (for example, 10 seconds) has elapsed, the timer contact 38 is closed (see FIG. 11k). Then, the motor 6 starts driving again (FIG. 11b), and the shaft 13 starts rotating again in the direction of the arrow Δ.

When the shaft 13 rotates in the same direction, the cam plate 14 acts to open the microswitch 36 for extending the heating time (FIG. 11J).

When the shaft 13 rotates in the direction of the arrow and reaches the original initial position, the microswitch 15 for holding the motor drive is opened by the action of the cam plate 14 (FIG. 11C).

The motor 6 stops driving (FIG. 11b), and the second relay 34 becomes inactive (FIG. 1). Hidden Bookbinding 1 returns to its original stop mode.

When the binding tape I 9 in this bookbinding machine is approximately the same as the width D /J' d + or d2 of the adhesive 22 in the center, the timer 37 is kept in a non-operating state. . Therefore, in this case, the heating time will not be extended as described above.
