Abstract

PURPOSE:To facilitate the take-out operation and packing operation of a continuous sheet of paper by forming the captioned mechanism with a center supporting member for supporting nearly the center part of a folded continuous sheet of paper and folded part end supporting members which support, while apply a vertical pressing force to, the vicinity of the folded parts of said sheet of paper. CONSTITUTION:Nearly the center part of a folded continuous sheet paper 3 is supported by a center supporting member 10 while, on the other hand, the vicinities of the folded parts 4 of the continuous sheet of paper 3 are supported by folded part end supporting members 11, 12. Further, the vicinities of the folded parts 4 of the continuous sheet of paper 3 are pressingly moved in the vertical direction making the folded parts press each other and compressing the folded sheet of paper 3 to remove its swelling. Also, since the center supporting member 10 supports the folded continuous sheet of paper 3 while raising its center part upward, the contact areas between the continuous sheet of paper 3 and the folded part end supporting members 11, 12 are very small even when the folded part end supporting members 11, 12 are displaced, without causing the damage of the continuous sheet of paper 3 due to the pressing movement of the folded part end supporting members 11, 12. As a result, the take-out operation of the continuous sheet of paper 3 and a packing operation can be made easier.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for supporting folded continuous paper used in printing presses and office machines, and more particularly, to a device for supporting folded continuous paper used in printing machines and office machines, and in particular to It relates to a mechanism that supports a continuous sheet of paper that is folded into a zigzag shape at its folding portion and fed from above.

Various mechanisms have been known to support continuous paper that has been folded in a zigzag pattern at the folding section. As the size increases, the shape becomes concave, so it is common to make the support surface convex and maintain the upper part substantially flat.

For example, Japanese Patent Application Laid-open No. 54-94927 discloses a base cradle 7,
A pair of rotary cradle 10 rotatably provided on both sides thereof.
11 is disclosed, and the rotary cradle 10.11 is configured so that when the weight increases in accordance with the amount of continuous paper to be supported, the end portions thereof on the side opposite to the base pedestal 7 gradually lower. When the supported continuous paper is to be taken out, the rotary supports io and ii are placed in a horizontal position so that the taking-out operation is facilitated. It is configured so that it can be done.

By the way, the continuous paper that has been folded and sent from above is in a swollen state at the folding part, and this swollen state is While it is difficult to eliminate the problem due to the weight of the paper alone, unless this swollen state is resolved, the work of taking out the continuous paper from the support mechanism and the packing work cannot be performed smoothly.

In conventional examples, including Japanese Patent Application Laid-Open No. 54-94927, the fed continuous sheets are simply stacked one after another, so the above-mentioned swollen state cannot be resolved, and the sheets are removed from the support mechanism. The drawback is that the continuous paper removal and packing operations cannot be carried out smoothly.

SUMMARY OF THE INVENTION An object of the present invention is to provide a support mechanism for folded continuous paper that eliminates these drawbacks.

[rl] A continuous sheet of paper having folding sections at predetermined intervals in the longitudinal direction for unraveling points is folded in a zigzag shape at the folding sections and is fed from above. a central support member that supports a substantially central portion of the folded continuous paper, and a center support member that supports the vicinity of the folded portion of the folded continuous paper;
and a folded part end support member capable of applying a pushing force in the vertical direction to the vicinity of the folded part.

The stopper supports approximately the center of the folded continuous sheet of paper with the central support member, supports the vicinity of the folded portion of the continuous sheet of paper with the folded portion end support member, and supports the portion of the continuous sheet of paper near the folded portion in the vertical direction. The contact area between the continuous sheet of paper and the folded edge support member is such that the center support member holds the continuous sheet of paper. Since the paper is supported in an angular shape, even if the folded end support member is displaced (it will be much smaller), the continuous paper will not be damaged by the friction caused by the pushing of the folded end support member. There is no.

Loss - Storm - ■ Hereinafter, a preferred embodiment in which the present invention is applied to a folding and cutting device for continuous paper will be described in detail with reference to the accompanying drawings.

Here, the first part is a schematic side view of the entire apparatus, Figures 2 to 6 are operation explanatory diagrams showing the folding, supporting, and cutting operations of continuous paper, and Figure 7 shows the initial entry state of the cutting blade. FIG. 8 is an enlarged side view showing the tip of the cutting blade.

As shown in FIG. 1, the folding member 1 is connected to an appropriate drive mechanism (not shown) so as to oscillate in the left and right directions in the figure, and is provided with a pair of guide rollers 1a and 1b above. Continuous paper 3 with folded parts 4 such as perforations formed at regular intervals in the longitudinal direction is fed to guide rollers 1a and lb by a pair of feed rollers 2a and 2b. is sent downward from the bottom end. The pendulum motion of the folding member 1 is
It is controlled to make one reciprocation every time two sheets of unit paper formed between each folding section 4 of the continuous paper 3 are sent out. Therefore, the continuous paper 3 is folded back at the folding portion 4 and sent downward in a zigzag pattern. Further, the rotation shaft of one of the guide rollers 2a includes:
The feed amount of the continuous paper 3 is detected based on the rotation speed and a control signal is issued, and a cutting command section 5 is connected which issues a cutting command signal when a preset feed amount is reached. The cutting command signal is sent to a control section 17 that drives and controls a cutting IJfr mechanism, which will be described later.

Below the folding member 1, a spiral body 6° 7.8.
(see FIG. 7) is connected to and rotatably supported by an appropriate drive mechanism (not shown). The drive mechanism is linked to a cutting command section 5, and is controlled by a control signal from the cutting command section 5. In the vicinity of the folding portion 4 of the continuous paper 3, there are two spiral bodies 6.8 or 9 located on either the right side or the left side in the figure according to the movement of the folding member 1 among the respective spiral bodies 6, 7, 8, 9. 7.9
It is placed on top and is sequentially sent downward as each spiral body 6, 7, 8, 9 rotates. This feeding operation ensures that the continuous paper 3 is folded at the folding section 4.

Next, the +Ii structure for supporting folded continuous paper will be explained.

As can be seen in FIG. 1, each helix 6. 7. 8゜9
A solid shaft 10, which is a central support member, is supported below the lifting table 28 so as to be able to move up and down via an air cylinder 29 which is driven by a control signal from the cutting command unit 5.
The motor 30, which is provided to sandwich the solid shaft 10 and is driven by a control signal from the cutting command unit 5, is driven to perform a symmetrical up-and-down motion around the end of the solid shaft 10 through a crank mechanism. A support table 13 consisting of a pair of support plates 11 and l'2 serving as folding end support members is disposed. The solid shaft 10 carries a folded continuous paper 3
When the continuous paper 3 is taken out to a transport conveyor 27 (described later), it is in the lowered position (as shown by the imaginary line in FIG. 1), but normally it is in the raised position to support the folded continuous paper 3. do. In this way, the solid shaft 1
0 supports the folded continuous paper 3 in the raised position, the lower part of the stacked continuous paper 3 is supported in a square shape, and the pair of support plates 11 and 12 support the folded continuous paper 3. The vicinity of the folded portion 4 is supported,
Even when the pair of support plates 11 and 12 move up and down, the contact portion between them and the continuous paper 3 remains in the vicinity of the folding portion 4.

The above-mentioned lifting platform 28 has a pair of supports 31 (only one is shown).
A chain 34 is attached to a pair of sprockets 32 and 33 so as to be movable up and down. The sprocket 33 is connected via an electromagnetic clutch (not shown) to the output shaft of a pulse motor 35, which is driven by the cutting command section 5. When the driving force of the pulse motor 35 is transmitted through the pulse motor 35, the lift table 28 moves counterclockwise in FIG. And, this descending distance is 6 degrees 7.8 degrees for each spiral body of the support table 13.
9, the amount of support for the continuous paper 3 that is reliably folded into a zigzag shape in the folding section 4, in other words, the - pair of feed rollers 2a
, 2b is controlled in accordance with the feeding of the continuous paper 3 by .

In addition, an air cylinder 1 is provided below the lifting platform 28.
8 is provided, and the air cylinder 18 has its drive control section 19 linked to the cutting command section 5, so that the air cylinder 18 projects its rond in response to a control signal from the cutting command section 5, and moves the lifting platform 28 to the support table. 13.

Next, the cutting mechanism will be explained. As shown in FIG. 1, the cutting blade 14, which is located between the support table 13 and the folding member 1 in the standby state, is attached to a rodless cylinder 21 connected to an air cylinder 20. It is disposed so as to be able to reciprocate in the upward and leftward directions, that is, to be able to protrude and enter from the direction of the folded portion 4 on each spiral body 6.8 with respect to the continuous paper 3. In addition, the air cylinder 2
The support member 22 to which 0 is attached is fixed to an elevating body 23, and this elevating body 23 is driven by the rotational driving force of a threaded rod 25 rotated by a motor 24 to move the guide member 26.
It moves up and down as guided by. Therefore, the cutting blade 14 is also moved up and down by the drive of the motor 24. Further, the motor 24, the air cylinder 20, and the rotorless cylinder 21 are each connected to a control section 17, and each is driven and controlled by the control section 17 (No. 8). As is clear from FIG. 7, the cutting blade 14 has an approximately squid-shaped planar shape.As can be best understood from FIG. y with
An i-plate-shaped guide blade 15 is fixed so as to sandwich the tip end surface from above and below.

Further, in correspondence with the lowest position of the support table 13 (the state shown by the imaginary line in FIG. 1), a pushing motion is performed to discharge the folded and cut continuous paper 3 on the support table 13 onto the conveyor 27. A member 16 is connected to an appropriate drive mechanism (not shown) and is provided so as to be able to reciprocate in the left and right directions in the figure.

Next, the operations of folding, supporting, and cutting the continuous paper in the above-described embodiment will be explained based on FIGS. 1 to 7.

FIG. 1 shows the starting state in one cycle of the folding and cutting operation, in which the support table 13 is in the uppermost position, the solid shaft 10 is also in the raised position, and the cutting blade 14 is attached to each spiral body 6, 8. It is in a standby state located slightly above the top surface. Due to the pendulum movement of the folding member l, the continuous sheet 3 begins to be folded in a zigzag manner at its folding portion 4, and each spiral body 6. 7. 8. 9, it is folded up securely, and it sequentially falls toward the support table 13.

As is clear from FIG. 1, the center part of the folded and fallen continuous paper 3 is located on the solid shaft 1 which has been raised to the uppermost position.
0, while the vicinity of the folded portion 4 is supported by a pair of support plates 11 and 12, so that the other portions of the continuous paper 3 located on the lowest surface are supported by the solid shaft 10 and the pair of support plates 11 and 12. The folded continuous paper 3 does not touch the plates 11 and 12, and each support plate 11, 12 of the support table 13 is raised and lowered by the motor 30.
The vicinity of the folding portion 4 of the continuous paper 3 is pushed in the vertical direction, and the continuous paper 3 is pressed against each other and gradually compressed in the vertical direction.Furthermore, the lower part of the continuous paper 3 is supported at the top of the continuous paper 3 in the shape of a square. As a result, newly falling continuous paper sheets 3 are stacked one after another in a state that is always kept almost horizontally (Second
(see figure), the support table 13 is configured so that the pair of support plates 11 and 12 are driven by a pulse motor 35 driven by a control signal from the cutting command unit 5 according to the amount of continuous paper 3 supported. It is lowered together with the lifting platform 28 while moving up and down.

Then, when the support (2) of the continuous paper 3 on the support table 13 reaches a preset desired amount, this is detected as the feed amount of the continuous paper 3 by the cutting command unit 5,
Air cylinder 2 is activated by a control signal from control unit 17.
0 is driven, the cutting blade 14 cuts the continuous paper 3.
is folded back on the 6°8 side of each spiral, and then the guide blade 15 rides on the unit paper of the continuous paper 3 located at the top formed by this folding, and the guide blade 15 is placed on the continuous paper 3 that is being folded. The cutting blade 14 enters into a predetermined position (see FIGS. 3 and 7), and the cutting blade 14 is controlled by the control unit 17.
The motor 24 is driven by a control signal from the motor 24 to lower the motor 24. At this time, the cutting blade 14 is attached to each spiral body 6.
However, by synchronizing the downward feeding speed of the continuous paper 3 in each spiral body 6.8 and the descending speed of the cutting blade I4 using a control signal from the cutting command unit 5, the cutting blade The cutting blade 14 descends without contacting each spiral body 6.8 (see FIG. 4).
It descends at the same speed as step 3.

Furthermore, the continuous paper 3 continues to be folded, and the support table 1
3 descends to a predetermined position, in other words, the cutting blade 14
When the amount of continuous paper 3 folded upward reaches a preset desired value H, the pulse motor 35 and the motor 30 are temporarily stopped by the il+ control signal from the cutting command section 5, while the control from the control section 17 The rodless cylinder 21 is driven by the signal. Therefore J'M+
As shown in FIG. 5, the blade 14 is driven to the left in the figure when the support table 13 is stopped from raising and lowering its pair of support plates 11 and 12, and the guide blade 15
breaks through the corresponding folded portion 4 of the continuous paper 3 and breaks the folded portion 4 at the front edge of the cutting blade 14. At this point, the motor 30 is stopped until each support plate 11.12 This is done when a sensor (not shown) detects that the side end of the solid ash shaft 10 is in a lowered state as shown in FIG. Further, at this point, due to the above-mentioned mutual pressing operations, the bulging state in the folded portion 4J is compressed and eliminated. Furthermore, since the folded continuous paper 3 is placed on top of the cutting blade 14 and has an appropriate weight on it, the continuous paper 3 will not shift as the cutting blade 14 moves. A smooth cutting operation is achieved.

When the folded continuous paper 3 is cut, as shown in FIG. As the chain 34 moves, it is lowered to the lowest position. Furthermore, air cylinder 2
9, the solid shaft 10 is lowered to the lowest position, and the pair of support plates 11 and 12, whose up-and-down movement has been stopped, become horizontal at the same height position as the support shaft 10, and the desired amount is cut. The continuous paper 3 in the folded state is taken out onto the conveyor 27 by the pushing member 16 (see the state shown by the phantom line in FIG. 1).

Subsequently, the IT 411 clutch was cut and the chain 34
After the support table 13 is brought to a free state, the support table 13 is raised to the uppermost position by the air cylinder 18, and the cutting blade 14 is released from the state of thrusting into the continuous paper 3 by each cylinder 20° 21, and is supported by the cutting blade 14. The folded continuous paper 3, which had been folded, is supported by the raised support table 13, while the motor 24 is reversed, the cutting blade 14 returns to the standby position, and the solid shaft 1O is also moved to the uppermost position. It returns to its original position and returns to the state shown in Figure 1. Thereafter, after returning the electromagnetic clutch to the connected state, the above-described operations are repeated to continuously fold and support the continuous paper 3 by a predetermined amount and then cut it.

In the above embodiment, it was explained that the folded continuous paper 3 on the support table 13 is cut when it reaches a preset desired amount, but in order to cut the folded continuous paper 3 at a desired position, the cutting blade The cutting command unit 5 that controls each cylinder 20, 21 and motor 24, which are the drive units of 14, is linked to a computer and command signals are sent from the computer, or the continuous paper 3 is cut by a printing machine or a computer printer. This can be done by attaching an instruction mark and driving the above-mentioned drive unit in response to a command signal obtained by looking at the cutting instruction mark. in this case,
The desired amount may be a constant amount or an amount that changes as appropriate.

It should be noted that the present invention is not limited to the embodiments described above, and can be applied to various continuous paper folding processing devices other than cutting devices, for example. In addition, the support mechanism does not necessarily have to be able to be raised and lowered by the lifting table 28 or the like. Furthermore, the inclination angle of the pair of support plates 11 and 12 with respect to the solid shaft 10 can be varied depending on the amount of support of the continuous paper 3. In addition, many different mechanisms may be adopted in addition to the above-mentioned embodiments for the mechanism for raising and lowering the solid shaft 10 and the mechanism for raising and lowering the pair of support plates 11 and 12. In addition, the central support member is not limited to the shaft body, and does not need to be able to be raised and lowered, and furthermore,
The fold end support member is not limited to a pair of plates that move up and down, but may be a pair or a single member that moves up and down.

As is clear from the above explanation, according to the present invention, the bulging state of the folded continuous paper can be eliminated by moving the folded part up and down to compress it, making it easier to take out and pack the paper. Furthermore, since the contact area between the continuous paper and the support mechanism is small, it is possible to achieve the beneficial effect that the continuous paper will not be damaged even if the folding end support member is displaced.
