Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention divides a wide sheet such as paper or plastic film into a plurality of narrow sheets and alternately distributes them to the front and back.
The narrow sheets on the front side and the rear side of the sorting can be moved in the width direction of the belt-like sheet by a moving mechanism, are supported between a pair of winding supports which can be positioned at a predetermined position, and are rotationally driven by a driving mechanism. The present invention relates to a winding width changing device for a winding support in a slitter winding machine that winds around a winding shaft or a winding core.

(Prior Art) In this type of slitter winder, since the division specifications such as the number of divisions of the sheet and the division position are changed, the winding support for supporting the winding shaft is correspondingly wide-width sheet. It is necessary to change the working width by moving it in the width direction and positioning.
Then, as a conventional winding width changing method, the current position of each winding support is stored in the storage unit of the control device as a distance from a fixed point common to all the winding supports, and when the division specification is changed, After the operator selects the take-up supports to be used and the take-up supports not to be used, the positions are set by setting the required intervals for all the take-up supports, and then set by the worker. The control device calculates the moving direction and distance of the winding support from the condition and the current position of the winding support corresponding to the condition, and commands the movement mechanism of the winding support to move based on the calculation result. What is done is known from Japanese Patent Publication No. 59-14158.

(Problems to be solved by the invention) However, the splitting specification of the slitter winding machine changes in an extremely wide range, and for example, a slitter winding machine (primary slitter winding machine) that divides and winds a raw sheet having a width of about 6 m. ), The number of divisions changes from 2 to 14,
The division width also varies. In the case of the primary slitter winding machine, seven pairs of winding supports are provided for each of the distribution front side and the rear side.

According to the conventional type, since the control device stores the current positions of the winding supports for each 7 pairs, each of them indicates a new position. It is necessary for the operator to consider the new position of the support, and the time spent for this thinking increases in proportion to the number of winding supports and the complexity of the division specifications, resulting in poor workability. . Moreover, when the allowable range of the sheet division width in the slitter winding machine is wide from a very wide width to a narrow width, there is a difference in the winding function in the winding support due to the relationship of the occupied space and the load for winding. In such a case, the operator must set the winding support having a function suitable for the width of the narrow sheet so as to correspond to the narrow sheet. In addition, in order to supply the winding amount detection signal accompanying the growth of the sheet roll to the winding tension control device or the winding contact pressure control device, when a winding amount detection device is provided on a specific winding support. However, the operator must consider in the setting stage so that the particular winding support is always used for winding, and the work is extremely troublesome and difficult.

Furthermore, when moving the winding support for changing the take-up width, accuracy is poor unless the moving speed is kept relatively slow. There is also a problem that there is a large difference in the time required for changing the working width depending on the procedure of deciding which position to attach.

(Means for Solving Problems) Therefore, according to the present invention, a wide sheet is divided into a plurality of narrow sheets and alternately sorted forward and backward, and the narrow sheets on the front side and the rear side are sorted by a moving mechanism. A slitter winding device that is independently movable in the width direction of the belt-shaped sheet and is supported between a pair of winding support members that can be positioned at a predetermined position, and is wound around a winding shaft or winding core that is rotationally driven by a drive mechanism. In the machine, a moving distance measuring signal transmitting means is provided on each of the winding supports, and the control device for receiving the signal stores the current position of each winding support, and when a new division width or division position is set, It is characterized in that the winding support body to be moved to the position corresponding to and the moving procedure thereof are selected.

(Operation) Each of the winding supports can be independently moved by the moving mechanism in the width direction of the belt-shaped sheet and can be positioned at a predetermined position, and the movement amount is clarified by the movement distance measurement signal transmitting means. On the other hand, the control device stores the operating or rest position of each winding support, that is, the current position.

Therefore, when a new division width or division specification of division position is set, the control device compares the setting condition with the stored current position of each winding support to satisfy the setting condition and execute it. A suitable transfer procedure. Then, according to the moving procedure determined by the control device, each winding support is moved to a predetermined position to change the winding width. The winding support moves while transmitting a movement distance measurement signal, and the signal is always input to the control device, so the control device issues a stop command to the winding support which has reached a predetermined position and stops it. Excuse me. Then, the control device stores the position of the winding support body after the stop as the current position in the winding support body.

(Embodiment) FIG. 1 is an explanatory view of an embodiment of the present invention, and FIG. 2 is an elevational view showing an example of a slitter winding machine to which the present invention is applied.

The wide sheet S unrolled by the roller 1 is divided into a plurality of narrow sheets S'by a slitter K and distributed to the front side and the rear side. The narrow sheet S'is divided into a front side and a rear side. A well-known winding shaft or core C, which is provided corresponding to the width sheet S ', has its both ends supported by a pair of winding supports, and is rotationally driven by a drive mechanism (not shown) individually or at a common required winding torque.

Therefore, the distance traveled or the position of each winding support can be determined by comparing the number of pulses emitted by the pulse generator 11 with the number of individual or common reference pulses on the winding support.

The output signal from the control device 14 of FIG. 1 is a signal directed to the engagement / disengagement drive section 9 of each winding support body, and is an engagement / disengagement command signal. Similarly, the output signal from the control device 14 is a signal directed to the motors M1 and M1 which are screw shaft drive devices, and is a right or left rotation drive command signal for the screw shafts 7 and 7. On the other hand, the input signal to the controller 14 is the pulse generator of each winding support.
It is the winding support movement amount measurement signal from 11.

In the case of this embodiment, the slitter K and one guide base 15 common to the front side and the rear side of the distribution provided in the width direction of the wide sheet are supported and provided corresponding to the narrow sheet S '. The supporting frame T'for supporting both ends of the touch roller T thus formed also has the wide sheet S by the same method as that of the winding support body.
Can be mechanically moved in the width direction of the. That is, 16 is a screw shaft that passes through a support base 18 of each slitter K that is slidable on a guide base 17 provided in the width direction of the wide sheet in series, and that can be rotated forward and backward by a motor M2. The base 18 is a female screw or the like

Further, reference numeral 21 denotes a screw shaft which is supported by a guide base 15 provided in the width direction of the wide sheet and which passes through a slidable support frame T'in series, and which can be rotated forward and backward by a motor M3. The reference numeral ′ includes a female screw 23 and an engaging / disengaging drive section 24. Of course, the touch roller and the slitter may be moved by using another mechanical moving mechanism or by pushing or pulling by a worker himself / herself.

FIG. 3 is an explanatory diagram showing an embodiment of the control device 14 of the present invention. That is, 26 is a setting operation unit for setting the sheet division width or the division position, and operating the start and stop of the device,
27 is an input unit that receives a signal set by the setting operation unit 26 and an input signal, and converts the signal into a signal suitable for processing; 28 is a winding width changing program for a winding support, which will be described later, and each winding support. A storage unit that stores the current position and other information necessary for changing the take-up width, 29 an arithmetic processing unit that performs a predetermined arithmetic operation based on a command of a program, and 30 a required winding support for the procedure determined by the arithmetic operation. An output unit 30a that outputs an engagement / disengagement command signal to an engagement / disengagement drive unit 9 such as a nut and an output unit 30a that outputs a body movement command signal, and a screw shaft motor M1.

FIG. 4 is an embodiment showing an example of a flow chart of a program for changing the take-up width stored in the above-mentioned storage unit 28. Based on this program, the arithmetic processing unit 29 selects the procedure for moving the winding support. To do. The setting conditions in this embodiment are based on the sheet division width and the arrangement order of how to arrange and wind the sheet division width from the width of the wide sheet.

First, based on the new division width that has been set, this is calculated at the division position, and the interval between the division positions is also calculated (3
2). Then, the pair of winding supports to be moved to the winding position of the narrow sheet is assigned to the winding support (3
3). Next, the target position of the winding support moving to the winding position of the narrow sheet and the target position for retracting the winding support not used for winding are calculated (34). Next, whether or not the retreat is possible, that is, the take-up support not used at the retreat position of the take-up support provided between the pair of take-up supports used for take-up or on both sides of the take-up position. , And whether or not the winding support at each winding position has various winding conditions (when several types of winding supports are prepared according to the winding load,
Whether or not the winding support under the conditions suitable for the narrow sheet is arranged correspondingly, and when the winding amount detection device or the like is attached to the specific winding support, Whether or not it is used for winding, etc.) is calculated (35). If the above retracting is impossible or the allocation of the winding support does not meet various conditions, it is impossible to perform the positioning for changing the winding width with the pattern. It should be noted that it is not necessary to judge the conditions for the above allocation if the winding supports have the same specifications. Above (3
If the requirement of 5) is satisfied, then the time required to move the winding support is calculated (36). The calculation factors include not only the moving time of the winding support, but also the time required for the engagement / disengagement operation of the screw shaft 7 and the engagement / disengagement drive unit 9 depending on the case, in order to rotate the screw shaft 7 from the forward rotation to the reverse rotation. The required time is also a calculation factor. Then, the time calculated at this stage is
It is stored as the moving time in the allocation pattern for changing the take-up width of the winding support. Next, it is determined whether the allocation pattern of all or a predetermined number of winding supports is completed (37). If not completed, the process returns to the step (33) so that the moving time and the like can be calculated based on another pattern. If all or a predetermined number of winding support allocation patterns have been completed, for example, the pattern having the shortest movement time among the patterns stored at the position (37) is adopted and output to the output unit 30. .

Since the moving time of the winding support is almost proportional to the moving distance, the moving distance is calculated instead of the moving time.
You may compare the allocation pattern for changing the width in the said moving distance. Also, in selecting the pattern,
The control device 28 may automatically select the pattern having the shortest movement time (distance) among the feasible winding support assignment patterns, but several kinds of feasible patterns are displayed on the display unit 31. However, the worker may appropriately select from among them.

Next, with reference to the flow chart in FIG. 4, an example of the actual change of the width will be described with reference to FIGS. 5 and 6. That is, the winding supports 50a and 5 in the state shown in FIG.
0b, 51a and 51b, 52a and 52b (above, above drawing), 53a and 53
b, 54a and 54b, 55a and 55b, 56a and 56b (above, under the drawing)
Is changed based on the new division widths W1, W2, W3, W4. In addition, in the case of FIG. 6, the narrow sheet with the division width W1 on the leftmost side in the drawing is wound on the distribution side (upper side of the drawing), but the reverse is also calculated in the same manner (see FIG. 7). ). 60 is an arbitrary position for calculation and is a reference point common to all the winding supports (for example, a position where the number of pulses in each pulse generator is zero). Therefore, the current position of each winding support can be obtained as a position corresponding to the distance from the reference point 60. WA indicates the width of each winding support itself, and the winding axis C in each winding support of this embodiment.
The support point of is set as its center position. lm is the farthest position 61 of the moving region of the winding support from the reference point 60.
Is the distance to, and lo is the distance to the closest position 62 as well. Therefore, the moving area of the winding support is lm
It can be calculated with -lo. The storage unit 28 has the above-mentioned reference point 60.
Etc. are stored as conditions for changing the width, and the distance from the reference point 60 of each winding support 50a to 57b in the state of FIG. 5, that is, the current position of each winding support 50a is a1, 50b.
A2, 51a b1, 51b b2, 52a c1, 52b c2, 53a d
1, 53d is d2, 54a is e1, 54b is e2, 55a is f1, 55b is f2, 56a
Is stored as g1, 56b is stored as g2, 57a is stored as h1, and 57b is stored as h2.

Therefore, the new division widths W1 to W4 described above are set. At that time, the distance from the reference point 60 to the left end of the first division width W1 in the drawing, that is, the distance from the reference point 60 to the first division position is also set. Set (width) as l1. Therefore, it is necessary to set the distance l1 from the reference point 60 to the first division position and the first division width.
W1, second division width W2, third division width W3, and fourth division width W4. Then, from the above set value, the division position, X1, X2, X3, X4, X5 from the left of the drawing, and the reference point at each division position.
The distance from 60 is obtained by X1 = l1 X2 = X1 + W1 = l2 X3 = l2 + W2 = l3 X4 = l3 + W3 = l4 X5 = l4 + W4 = l5. Further, the distance (interval) Δlo between the first division position X1 and the movement limit 62 of the winding support closest to the reference point 60 is calculated by Δlo = l1−lo, and the fifth division position X5 and the reference are obtained. Farthest position 61 of the moving area of the winding support from the point 60
The distance (interval) Δlm between and is calculated by Δlm = lm-l5. The values of .DELTA.lo and .DELTA.lm will be one of the judgment factors when it is judged later whether or not the winding support can be retracted. Next, the winding support is assigned. In this case, as described above, it is premised that the sheet having the division width W1 is wound by the front winding support member, so that the sheets having the division widths W1 and W3 are distributed to the front side. . Therefore, in the case of the front side, two pairs of the winding supports (50a and 50b, 51a and 51b, 52a and 52b) prepared are used. In this case, since there are three pairs of winding supports, there are a total of seven combinations using one to three pairs, and among them, three combinations using two pairs as in this example, That is, without using the winding supports 52a and 52b,
The first pattern, that is, the winding supports 51a and 51b are assigned to the dividing width W1, and the winding supports 51a and 51b are assigned to the dividing width W3.
Without using a and 51b, the split width W1 has a winding support 50a and 50b.
The second pattern for assigning the winding supports 52a and 52b to the dividing width W3, the winding supports 51a and 51b to the dividing width W1 without using the winding supports 50a and 50b. The winding support 52a
There is a third pattern that assigns and 52b. Since the winding supports are mounted on the same guide base, adjacent winding supports cannot be interchanged. Therefore,
Inexecutable patterns such as assigning the winding supports 52a and 52b to the dividing width W1 and assigning the winding supports 50a and 50b to the dividing width W3 are excluded from the beginning.

Then, the arithmetic processing unit 28 calculates the time required for changing the width, whether the evacuation is possible, etc. for all of the above three patterns or a predetermined number. The details are omitted because they are the same as the front side, but the winding support placed on the rear side.
With respect to 53a and 53b to 56a and 56b, the same calculation as the front side is performed.

Hereinafter, for convenience sake, description will be given based on the above-described first pattern shown in FIG.

First, in this case, the target position of each winding support is from the side closer to the reference point 60, 50a is the position of the distance l1 corresponding to the dividing position X1, and 50b and 54a are the positions of the distance l2 corresponding to the dividing position X2. ,
51a and 54b are positions at a distance l3 corresponding to the division position X3, and 51b
, 55a are assigned as positions of distance l4 corresponding to the division position X4, and 55b are assigned as positions of distance l5 corresponding to the division position X5.
Also, regarding the winding support not used, 52a and 52b on the front side, the current positions c1 and c2 from the reference point 60 and the winding support
Compared with the target position of 51b, 14 + WA ≤ c1, l4 + 2 WA ≤ c2
If so, the values are 14 + WA> c1 and l4, respectively, at the current position.
If + 2WA> c2, at least l4 + WA ≦ c1, l4 + 2WA ≦
Set the target position to be the position of c2. As a result, the winding supports 52a and 52b are retracted to a position that does not hinder the width change. However, since the moving area of the winding support is limited, in the case of the winding supports 52a and 52b, (WA +
The condition for saving is to satisfy the condition of Δlm) ≧ 2WA. In addition, when obtaining the retracted position between the winding supports to be used (winding supports 55a and 55b in FIG. 5) and when retracting a plurality of pairs of unused winding supports in one retracting area Also, whether or not the retreat is possible is calculated by comparing the retreat area and the width of the retracting support. If it is not possible to evacuate, it is impossible to change the width of the pattern, so return to the position indicated by reference numeral (33) in FIG. 4 without calculating the time required for the change, etc. Calculate based on the pattern. Further, at the same time as determining whether or not the retreat is possible, it is determined whether or not the winding condition for the pattern is satisfied. Further, in the case of this embodiment, the maximum winding width in each pair of winding supports is made different, and each pair of winding supports 50a and 50b, 52a and 52b (above, front side), 53a and 53b, 56a and 56b (above, rear side) drive on one side,
51a and 51b (above, front side), 54a and 54b, 55a and 55b (above,
The rear side) is driven on both sides. Therefore, the relationship between the sheet width of the division widths W1 to W3 and the maximum winding width of the winding support used is W1 ≤ WS _max , W2 ≤ WD _max , W3 ≤ WD _max , W4 ≤ WS _max (respectively). However, it is assumed that the division widths W2 and W3 need to be driven on both sides, and the division widths W1 and W4 are widths that can be driven on one side.
_max is the maximum winding width for a pair of double-sided drive supports, W
S _max is the maximum winding width on the pair of winding supports driven on both sides. ) It is necessary to meet the requirements of. Therefore,
When the above requirements are not satisfied, the position is returned to the position of the reference numeral (33) in FIG. 4, as in the case where the evacuation cannot be performed as described above. Further, in the case of this embodiment, a winding amount detecting device is attached to the winding supports 51a, 54a and 55a, and the detection signal is input to the winding tension control device. Therefore, at the time of winding, the winding support 51a, 54a or 55a must be arranged so as to correspond to any sheet, and the arithmetic processing unit determines whether the winding support is arranged. To judge. Then, if it is not arranged, it is returned to the position of the reference numeral (33) in FIG. 4 as in the case where the retreat is impossible. Regarding the latter two conditions among the above three conditions,
It is also possible to exclude in advance an allocation pattern that does not match the condition.

When the above conditions are satisfied, the required moving time in the width change pattern is calculated.

First, the front winding support will be described. In this case,
Winding support phase 50a that moves according to the new division widths W1 and W3
And 50b and 51a and 51b both move toward the right side in the drawing, the screw shaft 7 for moving the winding support described in FIGS. 1 and 2 can rotate in only one direction. Is enough. The take-up supports 52a and 52b satisfy the above-mentioned withdrawal requirement, and the current position is the target position.
Therefore, the time required to change the take-up width of the front winding support is calculated as the moving time of the winding support having the longest moving distance in the comparison of the moving distances of the winding supports 50a, 50b, 51a, 51b. Good. An example of how to obtain the movement time is an example of the winding support 51 located at a distance b1 from the current reference point 60.
Explaining a, the current position of the winding support is b
1, the target position is l3, so the movement distance is l3-b1
The moving time T3 can be calculated by T3 = (l3-b1) / V (V: moving speed). Further, the moving time T1 of the winding support 50a, the moving time T2 of the winding support 50b,
The moving time T4 of the winding support body 51b is also obtained by the same method. Then, in the comparison of the values of T1 to T4, the largest value (in the case of this embodiment, it is assumed that T3 is the maximum value) has the largest value, and the required travel time on the front side in the allocation pattern for the width change. Calculate as

By the same method, the required moving time in the take-up width changing pattern of the take-up support on the sorting side is also calculated. In addition,
In the case of the rear side winding support, unlike the front side, the right side winding support (55a and 55b, the required travel time for each is T9, T10).
Is. However, the target position l5 of 55b is assumed to be the same as the current position f2), and the left-side winding support (54a and 54b, the required travel times are T7 and T8, respectively), and the left-hand side is retracted. Take-up support (53a and 53b, the time required for each movement is T
5, T6), and there are unused winding supports (56a and 56b) whose current position is the target position. Therefore, in the case of the rear side, it is necessary to rotate the screw shaft 7 in the forward and reverse directions. Therefore, the time required to move the rear side winding support member is the largest value among the above T5 to T8 (in this embodiment, the above T7 is assumed to be the maximum value), and the value of T9 is added,
Moreover, it is calculated by adding the time TC required for switching the screw shaft 7 from the normal rotation to the reverse rotation.

Therefore, the required moving time in the take-up width changing pattern is longer than the required moving time of the rear side winding support body. In other words, if T7 + T9 + TC> T3,
The sum of T7, T9, and TC is (l4-f1) / V + (l2-e1) / V + TC. If it is the opposite of the above, the value of T3 will be the required travel time. The time TC required to switch the screw shaft 7 from the normal rotation to the reverse rotation may be ignored if the value is small.

As described above, in FIG. 6, the sheet having the division width W1 is wound on the distribution front side, but it is naturally possible to wind it on the distribution rear side as shown in FIG. It can be considered (details are omitted because they overlap with the description of FIG. 6). Therefore, the arithmetic processing unit 29 is
With respect to the allocation pattern as shown in the figure, various conditions such as evacuation and the required moving time in each allocation pattern are calculated. When setting the division width, it is set whether the sheet having the specific division width is arranged on the distribution front side or the rear side, and one of the sheets in FIG. 6 and FIG. It is also possible to calculate only the allocation pattern for changing the width under the condition.

In this way, the arithmetic processing unit of the control device performs the arithmetic operation for all or a predetermined number of allocations of the winding support for changing the take-up width, and outputs the procedure determined automatically or by an operator's arbitrary selection. Even when the control device automatically selects the allocation pattern for changing the take-up width of the winding support, the operator may once confirm it.

The output unit 30a of the output unit 30 which has received the above output compares the target position and the current position of the moving winding support, and outputs the output unit 30b.
According to the rotation direction of the screw shaft output by, the engagement command is issued to the engagement / disengagement drive unit of the required winding support body so as to reduce the difference. Of course, since there is only one screw shaft 7, it is not possible to perform right and left rows at the same time. Therefore, when the moving direction is both the left and right directions (rear side of FIG. 6), a rotation command is issued to the screw shaft drive motor M1 (30b) so as to perform one direction, for example, rightward first, and at the same time, rightward. The engagement is commanded only to the engagement / disengagement drive section of the winding support. Then, when the movement of the winding support to the right (left) is completed,
The movement of the winding support moving to the left (right) starts. From the moving winding support, momentary signals are input to the control unit.
It is input to 27. Therefore, the control device determines whether or not the difference has become zero, and issues a disengagement signal to the engagement / disengagement drive unit 9 of the winding support body which has reached the target position, that is, the difference is zero, and stops this. , The stop position is stored as the current position of the winding support body (storage unit 28).

FIG. 8 shows another embodiment of the allocation pattern of the winding supports for changing the winding width of the winding supports. In this embodiment, in order to save the operator the trouble of setting the arrangement of the divided sheets, a predetermined allocation pattern is stored in advance in the storage unit of the control device, and the control device itself is stored according to the number of divided sheets. Asks for an array, etc. Then, the allocation pattern here is as shown below. That is, when positioning the slitter and the winding support, even if the division width of each narrow sheet divided from the wide sheet is known, the order in which the narrow sheets of each division width are arranged is determined. If not, the dividing position of the sheet cannot be determined. Further, even if the division position and the division width are determined and the width of the narrow sheet to be wound and the arrangement thereof are decided, which pair of winding supports is arranged corresponding to the winding position of the narrow sheet. If not decided, the target position of each winding support cannot be decided. Therefore, in order to automatically determine the target position of the winding support as long as the required division width of the narrow sheet is determined, if the division number of the wide sheet and the division width are given, the width can be reduced according to the division width. Predetermine how to arrange the sheets, that is, the allocation pattern of the narrow sheets and which winding support is used and how to arrange according to the division number of the narrow sheets and the division width of each divided sheet. Keep it. In this embodiment, the above pattern is stored in the storage unit as an allocation pattern.

The function of the winding support (different for high load and low load, and attached with the winding amount detecting device) is the same as that of the embodiment shown in FIGS. Further, in the case of this embodiment, the wide sheets S are arranged so that the center thereof corresponds to the center position 70 of the moving region of the winding support, and the widest sheet after division is the widest sheet. Are arranged so that a part or an end of the sheet is on the center position, and the other sheets are sorted in the order of increasing width from front to back and to the left and right. 1c indicates the distance from the reference point 6 to the center position 70.

Therefore, the procedure for changing the take-up width based on the allocation pattern stored in the storage unit will be described below. First, each division width (W1, W2, W3, W4, W5) is set in the setting unit of the control device regardless of the size and arrangement of the width. Based on the above setting conditions, the arithmetic processing unit of the control device stores the size of each division width, the allocation of the slitter division width, and the allocation of the winding support in the storage unit and determines the allocation pattern. In the case of this embodiment, the relationship between the division widths is W1>W2>W3> W4.
> W5, and the relationship between W1 to W7 is the same as the relationship of the division width. Therefore, in FIG. 8, in order from the left, the sheets of the divided width W5 are wound and supported by the winding supports 53a and 53b, the sheets of the divided width W2 are wound and supported by the winding supports 51a and 51b, and the sheets of the divided width W1 are wound and supported. Sheets 54a and 54b have a width W3 and a support 52a and 52b has a width W3.
And 55b, respectively. When the correspondence between the divided sheets and the winding support is determined, the target position of each winding support is calculated next. However, even if the division width is determined, the target position of the winding support cannot be obtained unless the division position is determined. Therefore, in this case, the sum of the division widths (rounded down, the ear part lx to be wound by another dedicated winder)
(2, necessary part excluding lx2) is obtained, and the dividing positions X1 and X6 are located at positions equally distributed from the center position 70 of the winding work area (moving area of the winding support) to the left and right. The winding support (50a and 50b, 57a and 57b) that is not used is
If it interferes with another winding support, retract it.
The method may be the same as that of the previous embodiment.

After that, each winding support was treated in the same manner as in the previous example,
Move to each target position and change the working width.

When the ear portions lx1 and lx2 described above are wound in the same manner as other necessary portions, the value of the total width of the sheet to be supplied can be set in the setting unit of the control device, and the required portion is calculated from the above-mentioned total width value. The width of each of the ear portions lx1 and 1x2 may be obtained by subtracting the value of and subtracting the remaining value, and a predetermined winding support may be arranged at a position corresponding to this.

Further, when the length of the winding core does not match the divided sheet width, it may be stored in the control device in advance so as to calculate the target position in consideration of the difference.

The present invention has been described above based on the simple examples, but it goes without saying that the embodiments are appropriately changed and applied without departing from the scope of the claims by well-known techniques of designers and the like. Further, even a more complicated change of the width can be made by the same method as the case shown in the embodiment. Further, there are various other methods and programs for changing the width and the procedure is not limited to that of the embodiment.

In the moving method of the winding support shown in FIGS. 1 and 2, the screw shaft is first rotated at a relatively high rotation speed to roughly position the winding support, and then the rotation speed is reduced. By slowly moving the take-up support, a positional error due to inertia does not occur, and the take-up width can be changed without requiring much time. Also,
As a moving mechanism of the winding support, a type provided with an engagement / disengagement drive part such as a drive screw shaft dedicated to right and left rows and a corresponding female screw as shown in Japanese Patent Publication No. 54-33340 Alternatively, a method may be used in which the winding support is moved by rotating the female screw or the like for each winding support without rotating the screw shaft and engaging and disengaging the two. Furthermore, before distribution,
A rack in the seat width direction may be provided for each rear side, and a winding support may be provided with a pinion that meshes with the rack, and the winding support may be moved by rotationally driving the pinion. The support may be pulled and moved by an endless chain or the like.

In the illustrated embodiment, the current (operating) position of each winding support is stored in the storage unit of the control device.
In addition, a reference position for each winding support is set within the moving area of the winding support, and it is possible to confirm that each winding support has passed each reference position by photoelectric switch, proximity switch, touch switch, etc. If the count value of the Coulter at the time of passing is set as a reference value, it is possible to check each winding by comparing the number of pulses added and subtracted with this and the known distance from the reference point to the reference position. It is possible to grasp a more accurate current position of the support. Therefore, even if an error occurs, each winding support can be returned to the reference position once, and accurate counting can be performed again. The return to the reference position may be carried out each time the working width is changed, or in an emergency or at the beginning of work.

In addition to the type shown in the drawing, the slitter winder uses a swinging arm of a pair of winding supports for a stationary touch roller that has a large diameter and commonly contacts the front and rear sheet rolls. The supported roll shaft is moved toward the sheet roll, and the roll arm is swung along with the increase in the weight of the sheet to separate the roll shaft from the touch roller. And the supporting arm of the winding shaft swings or recedes linearly as the sheet becomes thicker, and the touch roller is held at a substantially constant position to apply a predetermined pressing force to the surface of the sheet roll. There is a type of winding a sheet, etc., and the present invention can be applied to any of them. Furthermore, the winding support may be in the form of an arm, or in the form of a frame or a trapezoid.

The present invention can also be interlocked with an automatic positioning device for a tool post of a slitter winding machine.

(Effect of the Invention) As described above, according to the present invention, when the winding support is moved along with the change of the winding width, the operator only needs to set the division width or the division position. There is no need to perform troublesome work such as whether to use or not to satisfy the specification condition with the allocation pattern. Therefore,
It is possible to reduce the labor of the operator and does not require a skilled element for the operation. Moreover, changing the width is optimal,
In addition, since the allocation pattern of the winding support that satisfies various conditions is automatically or selectively commanded, the time spent therefor can be significantly reduced, and the work time can be shortened and the productivity can be remarkably improved. You can measure.
