DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collating device used in a bookbinding process and a paper feeding device provided in the collating device.

[0002]

2. Description of the Related Art In a bookbinding process, a collating operation for collecting a plurality of different signatures in a predetermined order is performed. There is a flat binding method that simply stacks. A collating device that performs saddle stitching collation has a plurality of paper feeders arranged along an accumulation conveyor, usually called a gathering chain, and each paper feeder opens the signatures one by one and runs. The stack is fed onto a stacking / conveying conveyor inside, and the stacking / conveying conveyor is configured so that signatures successively supplied thereon are pressed and aligned by a piece, and a plurality of signatures are stacked.

As shown in FIG. 5, a feeder used here is a feed section 2 on which a stack of a large number of signatures 1 is placed.
And a soccer 3 for pulling out one end of the lowermost signature 1 and a feeder drum 5 having a pair of grippers 4a and 4b.
A wrap drum 8 having a stopper 6, a gripper 7 and a vacuum port (not shown), and a gripper 9
Conveyor 11 having an opening drum 10 and the like provided with a plurality of pieces (not shown) at a constant pitch.
It is arranged above. The accumulation conveyor 11 and the drums 5, 8, and 10 are driven by a line shaft (not shown) connected to a drive source, and run and rotate in mechanical synchronization. Soccer 3 and grippers 4a, 4
b is the feeder drum 5 by a cam mechanism (not shown).
The grippers 7 and 9 are operated by cam mechanisms (not shown) in synchronization with the rotations of the lap drum 8 and the opening drum 10, respectively. .

[0004] The sheet feeding device having the above structure performs a sheet feeding operation as follows. That is, the drums 5, 8, and 10 rotate in the directions indicated by arrows A, B, and C, respectively.
When the tip of the signature is pulled out, the gripper 4a or 4b of the feeder drum 5 grips the tip of the signature, and the feeder drum 5 rotates to pull out the signature 1 from the feed unit 2, and the signature 1 is moved to the stopper 6. Immediately before the collision, the gripper 4a or 4b releases the gripping of the signature. Signature 1
When the gripper 7 falls after hitting the stopper 6, the gripper 7 of the wrap drum 8 grips the longer end of the signature 1 and then the gripper 9 of the opening drum 10 breaks.
The shorter side of the lower end of the signature 1 is gripped, and the signature 1 is opened by rotation of the wrap drum 8 and the opening drum 10 . Thereafter, when the grippers 7 and 9 release the signature 1, the signature 1 falls downward, and is placed under a position immediately below the piece on the accumulating conveyor 11 running.

While the stacking conveyor 11 passes under a plurality of sheet feeding devices, signatures are successively placed thereon, and the stacking conveyor 11 travels while pushing the signatures with a piece. , A predetermined number of signatures are stacked and aligned. Collation is performed in this manner.

Also, in a collating apparatus for performing a flat stitching collation, a plurality of paper feeders are arranged along an accumulation / conveying conveyor, and each paper feeder closes a signature one by one. In this state, the stack is fed onto a running stacking / conveying conveyor, and the stacking / conveying conveyor is configured so that the signatures successively supplied thereon are pressed by a piece and aligned to stack a plurality of signatures. However, since the paper feeder used here does not need to open the signature, the paper feeder for saddle stitching shown in FIG.
This is a form in which the opening drum and the lap drum are eliminated, and the feeder drum pulls out the signatures one by one from the stack of signatures, and sends out the signatures to the accumulation conveyance conveyor.

[0007]

However, according to such a conventional configuration, there is a problem that a collation failure may occur when the operating speed is changed or the paper thickness or paper quality of the signature is changed. That is, in the sheet feeding device used for the saddle stitching type collating device, depending on the operating conditions, the signature cannot be opened by the opening drum and the lap drum, and good collating may not be performed. Also, when the signature sent out by the paper feeder gets on the running conveyor,
In some cases, they could not be aligned because they got on the pieces provided on the stacking conveyor. The latter problem has occurred not only in the saddle stitching system but also in the flat stitching collating device.

The cause of these problems has arisen because the collecting conveyor and each drum are mechanically synchronized, and soccer and each gripper are operated in synchronization with each drum. That is, in the conventional configuration, the relative operation timing of the soccer and each gripper in one cycle for feeding the signature is always constant regardless of the operation speed of the machine. The optimal operation timing varies depending on the operating conditions. Therefore, even if the operation timing is good under certain operating conditions, the operating timing becomes inappropriate if the operating conditions are changed.

Therefore, it is considered that the operation timing of the soccer or the gripper should be changed in accordance with the driving conditions in order to always perform good collation. To change the operation timing in the conventional apparatus, the machine must be stopped. In this case, the cam mechanism must be replaced or its position must be changed, which requires a very troublesome adjustment operation.

The first invention of the present application has been made in view of such a conventional problem. In a paper feeder of a type in which a signature is opened and supplied, the operation timing of the gripper can be easily changed, and It is an object of the present invention to provide a sheet feeder of a collating apparatus that can always open a signature and supply it to an accumulation conveyance conveyor even if conditions are changed.

[0011] The second invention of the present application can easily adjust the timing at which the signatures are dropped from the paper feeding device onto the accumulation / conveyance conveyor, and always keep the signatures on the accumulation / conveyance conveyor at a predetermined timing even when the operating conditions are changed. It is an object of the present invention to provide a collating device that can be put on a vehicle.

[0012]

According to a first aspect of the present invention, there is provided a feeder drum, an opening drum, and a lap drum. In a sheet feeding apparatus that feeds the paper by opening each unit, these drums are not driven mechanically synchronously, and at least two drive sources are used, and a servomotor is used as one of the drive sources. Further, the control device controls the servo motor so that the drum connected to the servo motor rotates in synchronization with the rotation of the drum driven by another driving source, but the speed during one rotation changes. It is configured to do so.

For example, when the feeder drum is driven by an appropriate drive source (not particularly limited), the lap drum is driven by a servomotor, and the servomotor is used by the lap drum to rotate the feeder drum. It rotates synchronously, but is controlled so that the speed changes within one rotation of the lap drum.

With this configuration, the two drums in the sheet feeding device, for example, the feeder drum and the lap drum rotate as a whole, but the speeds of the two drums change within one cycle. The operation timing of the gripper that operates in synchronization with the rotation of these drums changes. Thus, by changing the speed change pattern of the servomotor by the control device, the relative operation timing of the grippers respectively operated by the two drums can be changed.

In implementing the first invention of the present application, from the viewpoint of opening the signature satisfactorily, the operation timing of the gripper provided on the opening drum and the operation timing of the gripper provided on the opening drum are provided with respect to the operation timing of the gripper provided on the feeder drum. It is preferable to adjust the operation timing of the gripper. For this reason, it is preferable that a servo motor is connected to each of the opening drum and the lap drum so that the servo motor is driven separately from the feeder drum, and the servo motor is controlled in synchronization with the rotation of the feeder drum. . In this case, the drive source of the feeder drum is not particularly limited, and for example, a drive source of the collecting and conveying conveyor of the collating device may be used, or a motor synchronized with the driving source of the collecting and conveying conveyor may be used. Good. In addition,
Since the operation timing of the gripper provided on the opening drum and the operation timing of the gripper provided on the lap drum do not need to be adjusted so much when the operating conditions are changed, instead of providing servo motors on the opening drum and the lap drum, respectively, Both may be configured to be driven by a single servomotor. Conversely, a servo motor is connected to the feeder drum, the opening drum and the lap drum are driven by another drive source, and the servo motor of the feeder drum is synchronized with the rotation of the opening drum or the lap drum. The speed may be controlled to be variable.

According to a second aspect of the present invention, there is provided a collating apparatus having a stacking / conveying conveyor and a plurality of sheet feeders arranged along the feeding / conveying section to feed the signatures one by one onto the stacking / conveying conveyor . In each of the paper feeders,
Separate from the drive unit of the bearer and independent of the accumulation conveyor
A drive unit that can be driven upright is provided, and each drive unit
Driving the paper device independently of the stacking conveyor
Adjust the phase of each paper feeder with respect to the conveyor
It is configured to be able to.

The sheet feeding device used here may be a sheet binding device that supplies a signature in a closed state or a saddle binding device that opens and supplies a signature. When a paper feed device for saddle stitching is used, it is preferable to use the paper feed device according to the first aspect of the present invention. In addition,
When using the paper feeder according to the first invention of the present application, a plurality of motors are used as a motor for driving the paper feeder, but one of them may be driven in synchronization with the motor for driving the conveyor, Usually, it is preferable to synchronize the drive motor connected to the feeder drum with the conveyor drive motor.

In the collating apparatus according to the second aspect of the present invention having the above-described configuration, the drive units provided in the plurality of paper feeders respectively control the stacking conveyors of the respective paper feeders. > can be controlled phase, by adjusting the suitable phase in accordance with the operating conditions, the discharge timing of the signature by the paper feeder, can be adjusted and the arrival timing of the frame of the integrated conveyor, each sheet feeder signatures discharged from the can to put just in front of the piece on the integrated conveyor.

Etc. The soccer 3 and the gripper 4 are operated in synchronization with the rotation of the feeder drum 5 by a cam mechanism (not shown). Also, gripper 7
And 9 are operated by a cam mechanism (not shown) in synchronization with the rotation of the wrap drum 8 and the opening drum 10, respectively. However, unlike the related art, the drums 5, 8, and 10 are connected to the servo motors 20, 21, and 22, respectively, and are configured to be independently driven to rotate. An encoder 24 is connected to the feeder drum 5 so as to output a signal relating to the rotation angle position of the feeder drum 5. Reference numeral 26 denotes a control device for controlling the conveyor driving motor 14, the servomotors 20, 21, 22 and the like, and the function thereof will be described later. The servo motors 20, 21, 22
May be provided in each of the paper feeders 17 or may be common to a plurality of paper feeders 17 and drive may be transmitted to the corresponding drum of each paper feeder by a line shaft.

Next, the operation of the collating apparatus using the paper feeder having the above-described configuration will be described. The accumulating / conveying conveyor 11 is driven by a conveyor driving motor 14 and travels in the direction of arrow D.
Are driven by servo motors 20, 21, and 22, respectively, and rotate in directions indicated by arrows A, B, and C. Here, the conveyor driving motor 14 is rotating at a constant speed, and therefore, the collecting and conveying conveyor 11 is running at a constant speed. The servo motor 20 for driving the feeder drum 5 of the sheet feeding device 17 is controlled by a control device 26 based on a signal from the encoder 15 for detecting the traveling position of the piece 12 on the accumulation / conveyor 11 so as to synchronize with the traveling of the piece 12. Is controlled by The synchronization between the piece 12 and the servo motor 20 is determined so that the feeder drum 5 makes one rotation while the piece 12 moves by two pitches. The speed does not need to be constant in synchronization with the traveling of the piece 12, but may be changed as needed. The control device 26 can store a plurality of speed patterns of the servomotor 20 during one rotation of the feeder drum 5, and has a function of controlling the servomotor 20 according to the speed pattern. Now, for the sake of explanation, it is assumed that the control device 26 selects a speed pattern with a constant speed and rotates the servomotor 20 at a constant speed. Further, the control device 26
It also has a function of controlling the phase of a servo motor that drives the feeder drum 5 with respect to the travel of the accumulation conveyor 11.

Wrap drum 8 and opening drum 1
The servo motors 21 and 22 for driving the feeder drum 5 are controlled by a controller 26 in synchronization with the rotation of the feeder drum 5 based on a signal from an encoder 24 that detects the rotation position of the feeder drum 5. The rotation of the feeder drum 5 and the synchronization of the servomotors 21 and 22 are determined so that the wrap drum 8 and the opening drum 10 make two rotations while the feeder drum 5 makes one rotation. Also servo motors 21 and 22
The speed of the lap drum 8 and the opening drum 10
It is not necessary to completely synchronize with the rotation speed of the feeder drum 5 during one rotation, and an appropriate speed pattern can be taken. Controller 26, wraps the drum 8 and O
Servo motor 2 while punning drum 10 makes one rotation
A function of storing a plurality of speed patterns 1 and 22 and controlling the servomotors 21 and 22 according to the speed patterns is also provided. Now, for the sake of explanation, the control device 2
6 selects a constant speed pattern, and the servo motor 2
1, 22 are also rotated at a constant speed.

FIG. 3A is an operation timing chart of each member, and the horizontal axis represents the rotation angle during one rotation of the feeder drum 5. FIG. 3B shows the speeds of the servo motors 20, 21, and 22 at that time, and is constant in this embodiment. 2 and 3, the soccer 3 is linked to the rotation of the feeder drum 5.
Sucks and holds the tip of the signature at the lowermost end of the signature stack and pivots downward to pull the signature tip downward. Immediately after the soccer 3 stops sucking, the gripper 4a reaches the tip of the signature, the gripper 4a closes and grips the tip of the signature, and the feeder drum 5 rotates the signature 1 to feed the signature. Withdraw from 2. At this time, the other gripper 4b has already gripped and conveyed another signature. When the gripper 4b approaches the stopper 6, the gripper 4b opens to release the gripping of the signature. The signature collides with the stopper 6 to stop traveling and falls downward. At this time, the gripper 7 of the wrap drum 8 is at the lower end of the signature, and by closing the gripper, the longer end of the signature is gripped .
The ripper 9 grasps the shorter end of the signature 1 and opens the signature 1 by rotation of the wrap drum 8 and the opening drum 10 . After that, when the grippers 7 and 9 are opened and the signature 1 is released, the signature 1 falls downward, and is located immediately below the piece 12 (see FIG. 1) on the accumulating conveyor 11 running under the signature. get on. As described above, a part of the signature is supplied onto the stacking conveyor 11 by the first half rotation (0 to 180 degrees) of the feeder drum 5, and similarly, the second half rotation (180 to 180) of the feeder drum 5 is performed. 360 degrees) provides one more signature. In FIG. 3,
“Pass passing” indicates the timing at which the piece 12 passes through the position where the rear end of the signature falling from the sheet feeding device 17 falls.

In this paper feeding operation, the operation timings (intervals p, q, r, etc.) of the soccer 3, the grippers 4a, 4b, the grippers 7, the grippers 9, and the passing of the pieces are important, and certain operating conditions are previously determined. The cam is designed to be optimal for FIG. 3 shows a timing chart under the operating conditions. Under these operating conditions, good sheet feeding and collation are performed. However, when the operating conditions such as the operating speed, the signature paper quality, and the thickness are changed , there is a case where a good paper feed is not performed at this timing. For example, when the operation speed is set to be high, the gripper 7 or 9 may not grip the signature lower end at this timing, and the signature may fall without opening. for that reason,
In order to open and supply the signatures satisfactorily, it is necessary to advance the closing timing of the grippers 7, 9 and to secure the operation time. Therefore, in that case, the control device 26 selects a speed pattern of the servo motors 21 and 22 that respectively drive the lap drum 8 and the opening drum 10 so that the timing to close the grippers 7 and 9 is advanced.
The servo motors 21 and 22 are controlled according to the speed pattern. FIG. 4 shows a timing chart and a servo motor speed in that case. In FIG. 4, the servo motor 20 for driving the feeder drum 5 is rotating at a constant speed as in the case of FIG.
The operation timings of the grippers 4a and 4b are the same as those in FIG. However, the lap drum 8 and the open
Speed of the servo motor 21, 22 for driving the ring drum 10, as shown in FIG. 4 (b), and fluctuated between (while the feeder drum 5 is half rotation) of the drum 8 and 10 is rotated 1 Thus, the timing for closing the grippers 7, 9 is advanced. That is, the interval p from the opening of the gripper 4b to the closing of the gripper 7 is reduced, and the interval q from the closing of the gripper 7 to the closing of the gripper 9 is kept substantially constant. As a result, the grippers 7 and 9 can securely hold the lower end of the signature and open the signature satisfactorily even when the paper feeding device is operated at high speed.
In FIG. 4, the servo motors 21 and 22 are changed in exactly the same speed pattern. However, both speed patterns may be changed, and in that case, the interval q can be adjusted.

When the collating apparatus is operated at a high speed,
After the grippers 7 and 9 are opened and the signature is released, it is necessary to increase the interval r until the piece 12 reaches below the signature. If the interval r is not increased, signatures falling from the sheet feeding device 17 may get on the pieces 12, and good collation cannot be performed. Therefore, the control device 26 controls the servo motor 20 that drives the feeder drum 5 to shift the phase between the feeder drum 5 and the stacking / conveying conveyor 11. As a result, as shown in FIG. 4, the interval r becomes longer than in the case of FIG. 3, and the signature supplied on the stacking / conveying conveyor 11 falls just before the piece 12.

FIG. 4 only illustrates one operating condition, and the sheet feeding device and the collating device of this embodiment can be operated in various conditions. That is, by changing the phase between the accumulation conveyor 11 and the feeder drum 5 variously, or by operating each of the servomotors 20, 21, and 22 at various speed patterns, the arrival timing of the piece 12, soccer, The operation timing of the gripper and the like can be changed, and the optimum operation timing can be obtained for the operation conditions such as the operation speed, the signature paper thickness, and the signature paper quality. Here, the control device 26 determines the relationship between the operating condition and the phase between the accumulating conveyor 11 and the sheet feeding device 17 suitable for it, various speed patterns of each servomotor, and the operating condition and the speed pattern suitable for it. It has a database of relationships and the like, and by inputting operating conditions to the controller 26,
A desired speed pattern can be selected for operation. Also, an arbitrary speed pattern can be manually input or selected.

In the above embodiment, the feeder drum 5, the lap drum 8, and the opening drum 10 are provided with the servomotors 20, 21, and 22, respectively. However, the paper feeder of the present invention is not necessarily limited to this configuration. Not something. In the first invention of the present application, the operation timing between the grippers in the paper feeding device is adjustable, but at this time, it is not necessary to adjust the operation timing between all the grippers, and the The operation timing may be adjusted. For example, in order to perform good sheet feeding of signatures, mainly for the grippers 4a and 4b operated by the feeder drum,
Since it may be adjusted operation timing of the gripper 7 and 9, between the feeder drum 5 and the lap drum 8, and may be adjustable actuation timing of the gripper between the feeder drum 5 and an opening drum 10, therefore, the wrap drum 8 And the opening drum 10 may be mechanically connected and driven by a common servomotor. When the lap drum 8 and the opening drum 10 are driven by a servomotor so that the speed can be changed, the feeder drum 5 does not necessarily need to be changeable in speed. There is no need to use a servo motor as a drive source,
A motor driven at a constant speed may be used.

Further, in the above embodiment, the feeder drum 5
Based on the rotation of, a configuration for controlling the servo motor 21, 22 coupled to the lap drum 8 and opening <br/> drum 10, the wrap drum 8 or O alternatively
A configuration in which a servomotor connected to another drum is controlled based on the opening drum 10 may be used. In that case,
The motor that drives the reference drum is not necessarily a servomotor, but may be a motor that drives at a constant speed.

In the above embodiment, the servo motor 20 for driving the feeder drum of the sheet feeding device 17 is controlled in accordance with the frame position of the running accumulation / conveyance conveyor 11 so that the accumulation / conveyance of the accumulation / conveyance conveyor 11 and the sheet feeding device 17 are controlled. The phase is adjusted and the interval r in FIG. 4 is adjusted. The means for performing this phase adjustment is not limited to the case of using a servomotor, and can be changed as appropriate. For example, a synchro oscillator is provided on each of the drive shafts of the feeder drum and the accumulation / conveyor so that the phase difference becomes a desired value. Alternatively, the feeder drum driving motor and the conveyor driving motor may be controlled.

Although the embodiment in which the present invention is applied to the saddle stitching method has been described above, the second invention of the present application is not limited to the case of the saddle stitching method but can be applied to the flat stitching method. Needless to say.

Is configured to be driven by a servomotor, and the control device can be configured to apply a speed change within one revolution, so that the operation timing of the gripper operated by the drum can be adjusted. For this reason, it is possible to adjust the timing at a desired timing without stopping the machine and adjusting the cam mechanism in accordance with the change in the operating condition of the sheet feeding device, and it is possible to always supply a good signature.

Further, according to the second aspect of the present invention, since the phase can be adjusted between the stacking / conveying conveyor and each sheet feeding device, the signature discharge timing in each sheet feeding device and the timing of the stacking / conveying conveyor.
