Abstract

PROBLEM TO BE SOLVED: To correct meandering, in a slitter-scorer mainly cutting a corrugated cardboard sheet along the feed direction thereof to apply folds thereto, by simultaneously and integrally moving a plurality of processing units of slitters or scorers so as to follow meandering when meandering is generated in the sheet. SOLUTION: Processing units 24, 24' (slitter or scorer units) respectively positioned at a predetermined interval by servo motors are provided in the width direction of a fed corrugated cardboard sheet DS. Individual servo motors are respectively driven almost simultaneously to move the respective processing units 24, 24' all together by the same quantity in the same direction to allow them to follow the meandering in the width direction of the sheet DS to correct the meandering of the sheet DS. By this constitution, a moving mechanism or actuator exclusive for the correction of meandering used in a structure sliding the whole of the machine stand supporting a plurality of the processing units with respect to an anchoring base is dispensed with and an apparatus becomes simple in structure and inexpensive.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-like material processing apparatus which mainly feeds a belt-like material such as a corrugated cardboard sheet and performs cutting and creasing along the feeding direction. The present invention relates to a processing apparatus having a function of moving one or a plurality of processing units so as to follow the meandering when meandering in a direction.

[0002]

2. Description of the Related Art Conventionally, a slitter that feeds a strip-shaped corrugated cardboard sheet in the longitudinal direction and cuts along the feeding direction, a scorer that makes a crease along the feeding direction, and the slitter and the scorer are integrated. It is known that a slitter scorer, etc. FIG. 12 conceptually shows processing such as a slitter scorer for such a corrugated board sheet, and in the case of a slitter, a plurality of slitter units N1 to N4 are provided along the width direction of the corrugated board sheet DS, In the case of this example, three pieces are taken, and both sides are trimming pieces (ears).

By the way, generally, the processing units N1 ...
Sheet feeding is performed by center distribution in which the center of the machine base 100 including N4 and the center of the corrugated cardboard sheet DS match, but normally, the corrugated cardboard sheet DS is usually more or less misaligned (meandering) in the width direction. . The reason for this is, for example, deviation from the beginning when changing lots (changing sheets), errors in the support part for applying the base paper, and meandering that occurs during positioning of the positioning part from the new lot to the old lot.
There are also double-facer belt meandering and other causes. In any case, when the meandering occurs, the sheet center and the machine center shift as shown in FIG. 12B, and when the deviation becomes large, the width of the trimming piece becomes too large on the one hand and too small on the other hand. Trimming may not be possible if the limit is exceeded. Therefore, it is necessary to correct the meandering.

Conventionally, when a meander occurs, the machine base 100 supporting the processing units N1 to N4 is controlled to be displaced in the sheet width direction so as to follow the meander. That is, as shown in FIG.
A plurality of processing units N1 to N4 such as slitter units are supported via shaft members such as the above, and this machine base 100 is installed on the installation base 101 via linear bearings 102. A meandering follow-up motor 103, a screw shaft 104, and other actuators for meandering follow-up are provided, and the entire machine base 100 is installed by the dedicated actuator.
It is a structure that slides with respect to 01. Further, as the sheet edge detecting means 105 of the corrugated board sheet DS, for example, sensors S1 and S2 are provided so as to be movable in the width direction of the corrugated board sheet DS by the sensor moving motor 107, the screw shaft 106, etc. D
When running S, the seat edge should be between the sensors S1 and S2. These sensors S1 and S2 can be provided on both sides of the sheet DS, but when the sheet width data is received from the host production control device, only one side is sufficient.

The plurality of processing units N1 to N4 are moved and positioned by the respective servomotors SM1 to SM4 in the sheet width direction so that all or some of the processing units N1 to N4 participate in the processing in accordance with the processing command data. , After that, it continues to clamp without moving it during processing (things with a special clamp mechanism, servo lock etc. with a moving servo motor). If the sensor S1 is off (sheet not detected) and S2 is on (sheet detected), the sheet DS
Runs in the center state, but if both sensors S1 and S2 are turned on or off, the corrugated cardboard sheet DS is displaced from the center of the center to either side in the width direction. In order to eliminate this deviation (meandering), the meandering follow-up motor 103 operates to move the machine base 100 to the mounting base 10.
The sheet edge comes between the sensors S1 and S2 so that the above-mentioned cutting of the center distribution can be performed regardless of the meandering of the sheet DS.

[0006]

However, in such a conventional sheet meandering follow-up mechanism, it is indispensable that the machine base 100 can be slid on the installation base 101 via the linear bearing 102, and the machine base is slidable. Dedicated actuators (103, 104) for sliding 100 on mounting base 101 are required. Therefore, the structure of the device is complicated and the cost is high. That is, the plurality of processing units N1 to N4, etc. supported by the machine base 100 are servo motors SM1 to SM4 which are individual actuators.
The sheet is moved and positioned in the sheet width direction by the above, but such individual positioning and moving mechanisms (SM1 to S
M4) and a dedicated moving mechanism such as a servo motor 103 for sliding the machine base 100 itself, so to speak, it has a double moving mechanism, and thus the structure is complicated and the cost is high as described above. Can be said to occur.

An object of the present invention is to enable highly accurate meandering follow-up control without inviting a complicated structure of the device and a high cost.

[0008]

Means and effects for solving the problems: Claim 1 or 2
In the invention of claim 1, a predetermined processing unit (one or more) is provided on the premise of a belt-shaped material processing apparatus for processing a predetermined belt-shaped material such as a corrugated cardboard sheet in the longitudinal direction while processing the belt-shaped material along the feeding direction. The individual actuator, the meandering detection means or the meandering correction operation section, and the meandering follow-up means are included, and the individual actuator is also used as the meander-following actuator. The one or more processing units are, for example, slitter units, scorer units, etc., and are positioned in an array direction intersecting the flow direction in order to perform the processing in the flow direction.

The individual actuators firstly play the role of independently moving and positioning one or a plurality of processing units in the above-mentioned arrangement direction as in the conventional case, and secondly, as described later, the actuators for following the meandering. Used as. For example, mainly servo motors,
Each of the processing units can be moved by driving a nut for a screw or the like. The meandering detection means detects whether or not a belt-shaped material such as a corrugated cardboard sheet is meandering out of the regular feeding path. The meandering correction operation unit is, for example, a manual meandering correction button or the like, and is used when manually correcting the meandering. The meandering follow-up means, when the meandering detection means determines that the belt is meandering or by operating the meandering correction operation section described above, one or a plurality of slitters, scorers, or the like so as to follow the meandering. The individual actuators such as the servo motors are simultaneously operated for the processing units of. As a result, in the case of one processing unit, it moves independently with respect to the machine base, etc., and in the case of multiple processing units, the plurality of processing units can be moved simultaneously without changing the arrangement interval between the processing units. And it is to move integrally.

Here, there may be a mode in which all of the plurality of processing units naturally participate in the processing, but it is normal to use arbitrarily selected ones of the plurality of processing units in combination freely. In that case, the meandering follow-up means simultaneously moves only one or a plurality of processing units loaded to the processing position (does not move the resting processing units).
In addition to the above, not only the processing units participating in the processing for facilitating control, but also all the processing units including the processing units stopped at the non-processing position are moved together (integrally). It may be one.

According to the structure of claim 1 or 2, there is provided a structure in which a machine base is slidably provided on a conventional installation base,
Since it is not necessary to provide a dedicated actuator for following the meandering, the device structure is simplified and the manufacturing cost is low. That is, since the individual actuator for positioning one or a plurality of processing units is originally necessary for the processing unit, it is used for the original positioning operation of the processing unit and for the meandering follow-up operation. By using the dual function, a simple and inexpensive device can be realized while having a meandering tracking function.

As described in claims 3 and 4, the present invention is suitable for a slitter, a scorer or a slitter scorer, and when applied to a slitter scorer,
The meandering follow-up means includes each individual actuator of one or more processing units for the slitter and one for the scorer.
Alternatively, the individual actuators of the plurality of processing units are simultaneously operated as a whole, and the entire processing units of the slitter scorers are integrally moved.

Further, in the invention of claim 5, the above-mentioned meandering follow-up control is performed not as continuous control but as intermittent control (discontinuous control) which is executed by sampling at predetermined time intervals. That is, it is determined whether or not the belt-shaped material such as the corrugated cardboard is meandering at a predetermined sampling interval, and if the meandering is occurring, the individual actuators of the one or more processing units are actuated simultaneously. One or a plurality of processing units are simultaneously moved by a predetermined distance. The meandering follow-up control in this one-time sampling is completed once and is not continuous. This has the following significance. For example, in the processing state where a pair of upper and lower cutters of a slitter sandwiches and cuts a strip, and a pair of upper and lower scorers apply a nip pressure with a gap enough to crush the strip, the processing units shift to follow the meandering. If this is done, the torque further acts in the meandering direction (that is, it works so as to generate a forward and return ring), and hunting operation may occur over time. However, detection of the meandering amount and positioning movement for this meandering amount are By performing the discontinuous type control intermittently in time, the hunting operation as described above can be suppressed and high follow-up performance can be realized.

According to the sixth aspect of the invention, the moving speed at the time of following the meandering is set so that the following speed associated with the meandering following becomes faster as the feeding speed of the belt-shaped material such as a corrugated cardboard sheet becomes faster, and conversely becomes slower as the feeding speed becomes slower. adjust. In other words, if the meandering tracking is performed slowly even if the feeding speed of the strip is fast, it is difficult to quickly eliminate the meandering. The torque that causes the forward and return rings is easy to act. Therefore, adjusting the meandering follow-up speed in accordance with the feeding speed of the belt-like material satisfies both the requirements of realizing high follow-up performance and suppressing torque generation in the meandering direction. According to the invention of claim 7, the above-mentioned sampling interval is adjusted so as to become shorter as the feeding speed of the belt-shaped material becomes faster, whereby the influence of meandering does not extend for a long time in the feeding direction of the belt-shaped material. It is possible to quickly correct the meander even when viewed from the basis of the feed amount of the object.

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. In the embodiments shown in the drawings, a slitter and a scorer are provided as an example of a slitter scorer provided in series, but in the application of the present invention, a slitter single machine or a scorer single machine, and further, cutting of corrugated cardboard sheet, other than creasing It may be a general-purpose belt-shaped processing device for processing.

In FIG. 1, two slitter scorers 1 and 2 are arranged in series in the sheet feeding direction along a pass line PL of a corrugated cardboard sheet (hereinafter also simply referred to as a sheet) DS. The slitter scorer 1 is a unit in which the scorer 3 and the slitter 4 are adjacent to each other in series in the sheet feeding direction, and they form a unit. The same applies to the slitter scorer 2, and the slitter 6 is arranged adjacent to the downstream of the scorer 5. Scorers 3 and 5
Is a crease along the feeding direction (parallel to the feeding direction) made on the sheet DS by the scorer disks 10 and 12.
The slitters 4 and 6 sandwich and cut the sheet DS in the feeding direction by the upper and lower slitter blades 20 and 22. As described above, the slitter scorers 1 and 2 are provided in series so that while one slitter scorer is processing, the other slitter scorer prepares for positioning (setup processing) for the next order change. Then, by alternately using the slitter scorers 1 or 2, the order change can be performed without stopping the production line.

By the way, the slitter 4 or 6 is shown in FIG.
The scorer 3 or 5 is scored as shown in FIG. 3B, but the sheet width direction moving mechanism of each processing unit has the same configuration in the application of the present invention. The slitter 6 is typically shown in more detail in FIG. The slitter 6 is a disc-shaped slitter blade 2 that rotates in mutually opposite directions with a pass line PL of a corrugated cardboard sheet (hereinafter also simply referred to as a sheet) DS being sandwiched therebetween.
Nos. 0 and 22 form the main body of the slitter unit 24 (processing unit), and plural sets (for example, 5 sets) of the slitter unit 24 are provided in the width direction of the sheet DS (see FIG. 3). Then, by supplying the sheet DS between the slitter blades 20 and 22, the sheet DS
Is cut so as to be sandwiched along the feeding direction. Also, the slitter blades 20 and 22 of each slitter unit 24 are
It is configured to be movable between a processing position for cutting S and a non-processing position separated from the sheet DS. Further, the slitter units 24 are arranged so as to be movable in the sheet width direction, and the positioning is adjusted according to the number of picking and the changing of the picking width by changing the order.

That is, in FIG. 3, between the frames 26 of the slitter 6, the pass line PL of the sheet DS is provided.
A pair of beams 28, 30 (see FIG. 1) are laid in parallel at a predetermined interval in the vertical direction so as to sandwich the beam. The same number of moving members 36 as the slitter blades 20 are slidably supported on the upper beam 28 via a pair of guide rails 34, 34. A nut (36a in FIG. 4) rotatably provided on the moving member 36 is attached to both frames 26,
It is screwed to a screw shaft 38 that is installed and fixed to 26. Then, by driving individual servo motors 40 as individual actuators provided on each moving member 36,
The engagement of the gear 40a on the motor side with the gear 36b formed on the nut 36a drives the nut 36a to rotate, whereby the individual moving members 36 and thus the plurality of slitter blades 20 are individually moved and positioned in the horizontal direction. Is done.

In FIG. 2, below the moving member 36, a holder 4 is provided.
Reference numeral 4 is provided so as to be rotatable in a fixed angle range around a horizontal shaft 44a bridged between the frames 26, 26. Although not shown in detail, the shaft 44a is a drive shaft for simultaneously rotating the plurality of slitter blades 20. The holder 44 is a piston rod 46 of a cylinder 46.
When the cylinder 46 is extended, the holder 44 and thus the slitter blade 20 are rotated by the extension of the cylinder 46 to the non-processing position which is retracted upward from the processing position for cutting the sheet DS.

The lower beam 30 is also provided with the same moving member 36 as the upper one in a vertically symmetrical configuration, and the lower slitter blade 22 is also provided with the upper slitter blade 20.
Similarly to the above, the cylinder 46 retreats from the processing position to the lower non-processing position, but since it is functionally the same configuration as the upper side, the corresponding reference numerals are given and description thereof is omitted. The trimming pieces which are cut pieces on both sides of the sheet DS are sucked and collected by the suction duct 50.

Next, a block diagram of the control system will be described with reference to FIG. The upper-level production management device 60 manages and controls the entire production of the corrugator line that performs cutting and the like.
For example, it stores data such as the number and width of picking at the time of slitter, and the position of the scorer crease line. The control operation panel 61 includes a meandering correction button (61a, 61b) and the like for manually performing meandering adjustment described later. The line speed detector 62 detects the sheet feeding speed, for example, based on the number of rotations of the drive shaft of the sheet conveyor. Further, the meandering detection sensor 63 is provided with sensors S1 and S2 for detecting the sheet edge on one side or both sides of the sheet DS, for example, as shown in FIG. 7, and these sensor units 63 adjust the positions of the motor 64, the screw shaft 65 and the like. The mechanism allows the sheet DS to be moved in the width direction, and is positioned at a position where the sheet edge can be detected according to the sheet width when changing the lot. It should be noted that providing the sensor units 63 on both sides of the sheet DS has the meaning of knowing the sheet width (base paper width), but if data is supplied from the higher-level production management device 60 regarding the base paper width, the sensor unit 63 There is no problem with only one side of the sheet DS.

As the above-mentioned sensors S1 and S2, a photoelectric sensor or the like can be mainly adopted, but as shown in FIG.
The D sensor 67 may be arranged so as to cover the entire width of the sheet DS, or the CCD sensor 67 may be provided on both sides or one side of the sheet DS.

The upper production control system 60, the control operation panel 61, the line speed detector 62 and the meandering detection sensor 6 shown in FIG.
3 (or 67) is connected to the computer 71 via the I / O port 70. Computer 71 is a CPU
72, ROM 73, RAM 74, ROM
73 is a sequence program 7 for meandering tracking control.
3a is stored, and a necessary memory area is allocated to the RAM 74 in addition to the work memory 74a for temporarily storing the data of the meandering adjustment amount in one sampling and the data of the meandering adjustment speed.

Further, each of the above-mentioned servo motors 40 (SM
1 to SMn) are controlled by commands from the CPU 72 via servo motor positioning units (drivers) U1 to Un. A pulse generator PG is used as a rotation amount detector for confirming the rotation amounts of the servo motors SM1 to SMn.
1 to PGn are attached to the respective servomotors 40, and their rotation speed pulses are fed back to the servomotor positioning units U1 to Un.

In the example of FIG. 6, the meandering follow-up sequence program 73a is stored in the computer 71 of each slitter scorer. However, this program 73a is stored in the upper production management apparatus 60, and the upper production management apparatus 60 directly stores the program 73a. To drive servo motor positioning units U1 to Un
You may control.

Although the slitter 6 shown in FIG. 1 has been mainly described above, the scorer 5, and the slitter 4 and the scorer 3 of the other slitter scorer 1 also have individual actuators such as the servo motor 40 similar to the above. ing.

Next, an example of the control mainly including the meandering follow-up control will be described with reference to FIG. At T1, the production data such as the number of picks and the width of the picks are received from the upper-level production control device.
Based on this, each processing unit such as a slitter unit and a scorer unit is positioned at a predetermined position by the above-mentioned servo motor 40. Then, at T3, processing such as cutting and creasing as a slitter scorer is performed.

FIG. 10 conceptually shows the processing of the slitter scorer for the sheet DS.
Group of slitter units 24 and a plurality of (six in this example)
Although the scorer units 24 'of the pair) are drawn on the same axis, in practice, the plurality of slitter units 24 and the plurality of scorer units 24' are usually arranged along different axes adjacent to each other. is there. And normally, the machine center and the seat D of these processing units (24, 24 ')
The positional relationship between the sheet DS and the slitter scorer is set by centering so that the sheet center of S (corrugator center) coincides. In this example, the picking width S is three, and the folding width (flap width) is F.

Since the center is distributed as described above,
In the normal sheet feeding state, ears having substantially the same trimming width t occur on both sides of the sheet DS. However, if the sheet DS is meandered for some reason described above,
One of the trimming widths of the selvages on both sides of the seat is wide and the other is narrow and biased. When the meandering is large, the slitter unit 24 on the outermost side is disengaged from the seat edge. In order to follow such meandering, it is possible to simultaneously drive the individual servomotors 40 of the plurality of processing units 24, 24 'participating in the processing to change the arrangement intervals of these processing units 24 or 24'. Instead, move it by the same amount in the same direction. That is, FIG.
As shown in (c), the above-mentioned processing units 24 and 24 'are individually moved by the same adjustment amount (meandering correction amount) δ as the meandering amount δ. As a result, as if the processing unit 24,
The same meandering tracking (correction of meandering) is performed when the machine base supporting 24 'is displaced with respect to the installation base.

This flow is shown in and after T4 of FIG.
At T4, the line speed is fetched from the line speed detector 62 of FIG. 6, and the meandering adjustment speed and sampling time corresponding to the line speed are set. The meandering adjustment (correction) at T9 and T10 described later is performed based on the meandering adjustment speed set at T47. In the case of automatically following (adjusting) the meandering, at T6 after T5, sampling as to whether or not the meandering is performed is performed at regular intervals (for example, 0.5 seconds) of the sampling time set at T4. This is executed by the sensor 63 or 67 shown in FIG. 7 or 8. If there is a meandering (deviation) exceeding a predetermined amount, it will go through T7 and then T
At 8 the direction of the meander is determined. This is also the sensor 6 described above.
It can be easily determined by capturing the signal of 3 or 67.

Then, one side in the sheet width direction is set to the first side.
When there is a meandering (deviation) to the first side when the other side is the second side, the processing unit 24 of the slitter scorer is moved to the first side so as to follow it at T9.
The servomotors SM1 to SMn are driven so that the signals 24 and 24 'move simultaneously by a set amount (adjustment amount) commensurate with the meandering amount. If the meandering direction is on the second side, the servomotors SM1 to SMn are driven simultaneously and by the same amount so that the processing units 24, 24 'follow the movement and move to the second side. In this way, by simultaneously operating the servomotors that drive the individual processing units 24 or 24 'individually by the same amount, it is possible to move the entire machine base supporting the processing units 24 or 24' as a whole. It realizes simple meandering tracking control. It should be noted that the adjustment amount corresponding to the above-described meandering can be matched with the meandering amount by obtaining the sheet edge by image processing in the CCD sensor 67 of FIG. When a plurality of sensors S1 and S2 are provided as shown in FIG. 7, the more the number of sensors S1 and S2, the closer the actual meandering amount becomes. However, when the sheet edge detection is performed by the pair of sensors S1 and S2, it is simpler. 1 / of the detection interval of the sensors S1 and S2
The distance of 2 may be predetermined as the meandering adjustment amount.

After T11 in FIG. 9, T4 and subsequent steps are again executed at a predetermined sampling time to intermittently and repeatedly perform a meandering check, and the meandering control for one sampling time is performed as described above. With the intermittent open control, the so-called hunting operation is less likely to occur than in the case where continuous feedback closed control is performed. Further, it is easy to make the meandering adjustment movement amount per second considerably larger than the conventional average amount (for example, about 1 mm) (for example, about 5 mm), and thereby high followability can be secured.

When the meandering correction button on the operation control panel 61 of FIG. 6 is operated at T5, the direction of the meandering adjustment is also determined at T12, and T9 or T1 depending on the direction.
0 is executed, and the meandering adjustment (correction) is performed manually. When manually adjusting the meandering, the meandering adjusting speed and the meandering adjusting amount may not be uniquely determined on the program, but the meandering adjusting speed and the meandering adjusting amount may be manually determined. it can.

In the above description, the intermittent discontinuous meandering control is performed every predetermined sampling time, but the control system has the sensors 63 and 67 of FIG. 7 or 8 and the processing units 24 and 24 '. Etc. as a closed loop,
It is also possible to perform continuous closed meander control by feedback so that the deviation due to meandering approaches 0 as much as possible.

(C) Single-blade type slitter blades 90, 91
Alternatively, it may be 92. These single blades are, for example, 3m
The sheet is cut as thin as about m and rotated in the same direction as the sheet feeding speed (line speed) at about 2 to 4 times, for example. Such a slitter knife 90 may be received by the brush 93 as in the example of FIG. 10A, or may be received by the elastically deformable laminated ring 94 as in FIG. Further, as shown in (c), the slitter blade 92 may be structured to be inserted between the two receiving disks 96 normally biased by the spring 95 in the approaching direction.
