A driven wheel 65 to which a vertically downward force is applied by an air cylinder 63 in order to apply tension to the belt 58,
It is wound around the mandrel 57 and driven by drive wheels 69.

Reference numeral 140 denotes a carrying roller for carrying the sheet 11 on the stacking table 1 toward the mandrel 57, and the carrying roller 140 and the driving wheel 69 of the belt 58 are connected by a belt 142. 141 is a pressing roller, which can be moved up and down by an air cylinder 144. 143 is a stopper which can be moved up and down by an air cylinder 145.

FIG. 55 shows a state in which the sheet 11 is aligned for winding using the winding device of FIG. 54.
In this state, it stands by on the loading platform 1. In the figure, 11S is a work step composed of several sheets 11, and each work step 11S is sequentially shifted by d and stacked to form one work group 11G that is wound around the mandrel 57 at a time. There is. In the case of FIG. 55, the work group 11G, which is one group in 5 steps
Are configured.

FIG. 56 shows a prior art disclosed in Japanese Patent Laid-Open No. 4-332110, which is an apparatus for forming a work group 11G aligned as shown in FIG. In the figure, 1 is a loading platform, and 149 is a clamper composed of a block 148, an air cylinder 146, and a rod 147, which clamps and conveys a work step 11S cut in a previous step (not shown). Reference numeral 152 is a push-up rod, which is vertically driven by an air cylinder 153. A fastening member 150 is driven by the air cylinder 151.

Next, the operation of the prior art will be described. In FIG. 56, when the work step 11S cut in the previous step (not shown) is sent, the push-up rod 152 is pushed up by the air cylinder 153, and the tip of the work step 11S is pushed up. A clamper 149 grips this tip and conveys the work step 11S leftward in the drawing. After the work step 11S is conveyed to a predetermined position and positioned, the fastening member 150 fixes the work step 11S so that the work step 11S does not shift. After the tightening member 150 fixes step 11S, the clamper 149 releases step 11S.

The work group 11G thus arranged is placed on the loading table 1 shown in FIG. The placed work group 11G is stopped by the stopper 143 until it receives the signal of winding OK.

On the winding device side, the drive wheels 69 connected to the conveying rollers 140 drive the belt 58 to wind the work groups 11G group by group around the mandrel 57. At this time, the tensioning mechanism 60 including the air cylinder 63 and the driven wheel 65 applies tension to the belt 58, and the belt 5 changes due to the diameter change of the work iron core of the work group 11G wound around the mandrel 57.
8 acts to absorb changes in length.

The conventional apparatus is configured as described above, and when a number of sheets 11 are wound (an amorphous iron core is normally 2000 to 3000 sheets), the sheet is caused by the manufacturing apparatus for producing the amorphous sheet itself. Because of the thickness deviation characteristic of 11 in the width direction with respect to the longitudinal direction, the thickness of the work iron core after winding the sheet 11 may be greatly different on both sides of the mandrel 57 as shown in TA and TB of FIG. It was happening.

Further, in the work of pulling out the work iron core which has been wound up from the mandrel 57, the work is only done manually by the worker, and the work is dangerous because it is heavy, and the sheet 11 is thin. Mandrel 5
There is a problem that the sheet 11 in contact with the 7 side is easily deformed. In addition, it is necessary to align the sheets 11 by another aligning device before winding and remount the sheets on the stacking stand 1 of the winding device, which causes a problem of poor workability.

Further, in the conventional apparatus, the winding of the sheet 11 is performed only by driving the belt side and not by driving the mandrel 57 side. Therefore, when the number of the winding sheets 11 increases, the inside and outside of the work iron core are However, there was a problem that relative slippage occurred.

[0013]

【Example】

Example 1. FIG. 1 is a flowchart showing a method of winding an amorphous iron core according to the invention of claim 1.

And step A5 is a step of winding the work group.

Next, the operation of the above invention will be described. First, the operator sets a sheet for one iron core at a predetermined position on the stacking table (step A1). Next, the sheet is separated and aligned from the sheet for one work iron core by the work group to be wound at once at the winding section in the next step. There are various methods for separating and arranging in view of the relationship between the front end process and the rear end process, but in the present embodiment, a plurality of work steps called one step, which is composed of several sheets whose front ends are aligned with each other, is performed.

After the seat 11 is locally separated, the air cylinder 15 is operated and the separating plate 12 is rotated to completely separate the work step 11S from the seat block. Up to this state, the lifting pins 31 are in a state of being lowered from the upper surface of the loading platform 1.

Next, the variable I is set to 1 (step J3). Next, the process proceeds to step J4, and the work steps for the first step of one group are separated. In step J5, the work steps separated in step J4 are lowered onto the supply table which is the alignment table of the separation / alignment device. Next, assuming that 4 is initially set as n, since I ≠ n, the process branches to step J6 and proceeds to step J7.

In this case, unlike the case of not inverting shown in FIG. 19, the length of each sheet in each work step is longer on the upper side (FIG. 20 (b)). In this example, the number of steps is n = 4, and the shift amount for each work step is d.

Example 17 FIG. 17 shows claims 17 and 18.
FIG. 17 shows an embodiment of an apparatus invention for carrying out the invention of claim 16, that is, the invention of claim 16. 1 to 40 in FIG.
The description is omitted because it is the same as 5. 41 and 42 are clamp members having the same shape, and their positions are interchanged with each other. When the clamp members 41 and 42 are located near the loading platform 1, they function as an alignment platform, and when they are away from the work loading platform 1, they are in a standby state. 41a and 42a are clamp material pins, and 41b and 42b are clamp material pins 4 so that the clamp material pins 41a and 42a are fitted, respectively.
It is a hole made in 1, 42.

Reference numeral 43 denotes a pair of hands fixed to the connecting plate 44, which holds the grip 42c of the clamp member 42. A slide shaft 46 is connected to the connecting plate 44 and is linearly guided in the horizontal direction by a bearing 45 fixed on an elevating table 48. Further, a driving force is applied to the connecting plate 44 by an air cylinder 47 which is a retracting means fixed on the elevating table 48. The lift 48 is supported by a slide shaft 49, is linearly guided in the vertical direction by a bearing 50 fixed to the bed 29, and is lifted and lowered by an air cylinder (not shown).

Reference numeral 51 is a pair of reversing means, and the head 53 is driven up and down with respect to the column 52 fixed to the floor. Reference numeral 54 denotes a swivel shaft capable of swiveling and linearly moving, and the claw 5 that opens and closes.
A hand 55 having 6 is rotatably and linearly supported. Further, a pin (not shown) is attached to the claw 56 to prevent the clamp members 41 and 42 from being displaced when gripping and reversing the clamp members 41 and 42.

Next, the operation will be described. Now sheet 11
It is assumed that the separation thickness of one work step is set to t. After the sheet 11 is set on the loading platform 1,
The separating plate 12 is located at a position lower than the upper surface of the sheet 11 by t.
The elevating table 24 is positioned by the air cylinder 27 so that the tip 12a of the table is positioned. After that, the slider 14 is driven forward by the motor 23, and one end 12a of the separating plate 12 locally separates the sheet 11 at a point on the side surface C side which is lower than the upper surface A of the sheet 11 by t.

After the seat blocks have been locally separated,
The air cylinder 15 is operated to rotate the separating plate 12 around the shaft 13 to totally separate the work step 11S for one step of the sheet 11. Up to this state, the lift pins 31 are in a state of being lowered from the upper surface of the loading platform 1. After the sheet 11 is separated by one step, the air cylinder 27 is operated to lift the separation plate 12 together with the lift table 24. After that, the motor 23 rotates, and the slider 14 is further advanced while the work step 11S is placed on the separation plate 12, and brings the work step 11S on the separation plate 12 onto the clamp member 41 as the alignment table. After that, the air cylinder 27 drives the separating plate 12 downward, and the separated work step 11S is the clamp member 41.
Get down.

Thereafter, the separation plate 12 is entirely retracted together with the slider 14 by the rotation of the motor 23. At this time, the sheet 11 on the separation plate 12 is prevented from moving in the width direction by the pins 41a on the alignment base 41, which is a clamp member, and is positioned at a position sandwiched between the pins 41a on the alignment base 41. The separating plate 12 is horizontally moved and retracted, and then is rotationally driven by the action of the air cylinder 15, and only one end thereof is retracted rearward. By the above continuous operation, the work step 11S for one step is lowered onto the alignment table 41.

While the work step 11S lifted by the separating plate 12 is positioned on the aligning table 41 and the separating plate 12 is returned to the standby position, the remaining sheet books on the stacking table 1 are separated by the stacking table 1. It is displaced in the longitudinal direction of the sheet by a predetermined amount. Next, by the action of the air cylinder 27, the separating plate 12 is driven further downward from the upper surface of the sheet block left on the stacking table 1 by the work step thickness of one step. From this state, the separation plate 12 separates and lifts one work step by the procedure described above. After that, the separated sheet 11 is first dropped on the alignment table 41 by the above-described procedure.
Take it down 1. Furthermore, the separating plate 12 returns to the rear end position as described above. At this time, a two-step work step 11S, which is offset in the work longitudinal direction by a predetermined amount, is positioned on the alignment table 41. By repeating such a procedure n times, n steps of work step 1 in which each step is sequentially deviated by a certain amount
1 workgroup 11G composed of 1S is an alignment table 4
Aligned on 1.

After the 1 work group 11G is aligned on the alignment table 41, the clamp material 42 (same shape as the alignment table) held by the hand 43 is driven by the air cylinder 47 and positioned on the alignment table 41. To be done. After that, the lift table 48 is moved vertically downward by an air cylinder (not shown), and the clamp member 42 held by the hand 43 is lowered onto the alignment table 41. The one work group 11G thus aligned is sandwiched between the clamp members 41 and 42 having the same shape from above and below. At this time, the clamp material 41,
Since the pins 41a and 42a of 42 are fitted in the holes 41b and 42b of the clamp members 41 and 42 facing each other, respectively, the clamp members 41 and 42 and the clamp members 41 and 42 and the sheet 11 are not displaced from each other.

Next, the pair of heads 53 of the reversing means 51 rises until the position of the claw 56 reaches the position of the clamp members 41 and 42 which are stacked as described above. After that, the pair of hands 55 advances toward the clamp members 41 and 42 to move to the work group 1
1G is grasped by the claw 56 together with the upper and lower clamp members 41 and 42. After that, the pair of heads 53 are further raised in synchronization with each other, and the alignment table 41 positioned on the bed 29 is positioned.
The work group 11G is lifted together with the (clamping material). After that, the pair of hands 55 synchronously move 1 around the turning axis.
Rotate 80 degrees and invert the work group 11G. At this time, since the upper and lower clamp members 41 and 42 are engaged with the pins (not shown) attached to the claw 56, they do not shift relative to the claw 56. After the reversal, the pair of heads 53 descends, and the work group 11G is lowered onto the bed 29 together with the clamp members 41 and 42. The pair of hands 55 releases the clamp members 41, 42, and further the clamp members 41, 42
After being separated from, the pair of heads 53 further descends to the standby position.

Next, the hand 43 is driven by an air cylinder 47 which is a retreating means to move forward and reverse to grab the clamp member 41 which is turned upside down. Next, the lift 48 is driven vertically upward by an air cylinder (not shown), and the hand 43 holds the clamp member 41. Clamp material 41,
After the pins 41a, 42a of 42 have been raised up to the position where the pins 41a, 42a are mutually pulled out from the holes 41a, 42b, the pair of hands 43 are held by the pair of hands 43 while holding the clamp member 41, which is on the upper side after reversal, to the standby position. And is driven by the air cylinder 47. One work group 11G arranged as described above is inverted.

In this embodiment, an air cylinder is used to drive the separating plate 12 and the lifting table 48 up and down, but the invention is not limited to this, and a combination of a motor and a feed screw may be used. Is clear. On the contrary, the horizontal movement of the separation plate 12 and the movement of the loading table 1 in the longitudinal direction of the work are shown to be driven by a motor.
It is obvious that an air cylinder may be used.

According to this embodiment, the work group 1 in which the sheet blocks stacked on the stacking base 1 are rolled up at once
After separating 1G and arranging them into one work group 11G consisting of arbitrary n work steps, it is easy to invert the whole. Workgroup 11G
Since the work group 11G is clamped from above and below and the pins 41a and 42a are provided so as not to shift the work group 11G, it becomes easy to reverse the work group 11G without deforming it with a small force. Further, since the loading platform 1 is provided with the moving function, there is an effect that the device space is reduced.

Example 18. FIG. 21 shows an embodiment of the invention of claim 19. In the figure, reference numeral 57 denotes a mandrel which is rotatably supported by a main shaft (not shown), to which a force in the right direction is applied by an air cylinder (not shown). Reference numeral 58 denotes a belt, and the belt 58 is a driven wheel 5 that is rotatably supported around an axis fixed to the base plate 72.
9, the intermediate belt releasing portion 202 is formed and wound around the driven wheels 65, 66, 67, the driving wheel 68, and the mandrel 57 which are rotatably supported around the axis that is relatively movable with respect to the base plate 72. Reference numeral 60 is a tension applying mechanism that adjusts the belt length and generates belt tension, and 65 is a driven wheel that is rotatably supported on a slider 61 that is linearly guided by a linear guide 62. 63 is an air cylinder, which is fixed to the base plate 72 by a mounting plate 64, and the tip of the piston rod of the air cylinder 63 is connected to the slider 61.

Reference numeral 73 denotes a rotating plate, which is a rotating shaft 74 and a guide shaft 7.
5 is supported by the base plate 72 so as to be rotatable about a rotation shaft 74 as a fulcrum. Reference numerals 69 and 70 denote rodless air cylinders, and driven wheels 66 and 67 are rotatably supported on the sliders 69a and 70a. Of these, the air cylinder 69 is fixed to the rotating plate 73, and the air cylinder 70 is fixed to the base plate 72 with bolts 71. Reference numeral 80 is a block having a female screw that engages with the male screw of the adjusting screw 81, and is fixed to the base plate 72.

Reference numeral 82 is a spring disposed between the adjusting screw 81 and a plate 77 fixed to the rotating plate 73. The spring 82 is provided to the rotating plate 73 so that the driven wheel 66 always contacts the mandrel 57. The force is applied to the left of. Reference numeral 79 is an adjusting screw, which is engaged with a female screw of a bracket 78 fixed to the base plate 72, and prevents the rotating plate 73 from rotating more than necessary when the mandrel 57 retracts to the left in the drawing. Acts to prevent. The rotating plate 73, the rotating shaft 74, the guide shaft 75,
The air cylinder 69 and the spring 82 constitute a biasing unit that biases the driven wheel 66 on the delivery side of the amorphous sheet 11 toward the mandrel 57.

Next, the operation will be described. When the work group 11G is sent from the transport device from the previous step, the drive wheel 68 is driven by a motor (not shown) to rotate, and the work group 11G is wound between the belt 58 and the mandrel 57. At this time, the main shaft (not shown) fixed to the mandrel 57 is urged rightward in the drawing by an air cylinder (not shown), and as a result, the mandrel 57 is moved.
Is in contact with the driven wheel 67 via the belt 58. Further, since the air cylinder 63 pulls the slider 61 downward in the drawing, the belt 58 is in a state in which tension is applied without slackening.

The position of the rotary shaft of the mandrel 57 moves to the left in the figure because the outermost diameter of the work iron core increases as the work 11 is successively wound around it. When the work group 11G starts to be caught in the mandrel 57, there are more sheets between the mandrel 57 and the driven wheels 67 than the mandrel 57 and the driven wheels 66, only the leading end portion of the work group 11G ( FIG. 22). At this time, unlike the case of this embodiment, when the air cylinder 69 is directly fixed to the base plate 72 without the rotating plate 73 like the air cylinder 70, on the driven wheel 66 side, the work 11a that has been previously wound is caught. And belt 5
As shown in FIG. 22, a gap 83 is formed between the gaps 8 and 8.

In this embodiment, the driven wheel 66 is always in contact with the mandrel 57 via the belt 58.
Since there is no gap as shown in Fig. 2, the belt release part 2
At 02, the leading end of the sheet 11 is prevented from rising from the mandrel 57.

Example 19 FIG. 23 shows a flowchart of the invention of claim 20. In the figure, step K1 is a step for releasing the outer diameter locking mechanism of the mandrel, step K2 is a step for gripping the cylindrical work which has been wound up from the inside and the outside of the cylinder, and step K3 is for reducing the outer diameter of the mandrel. Step, Step K4 is a step of removing the work iron core from the mandrel,
Step K5 is a step of carrying the work iron core to the next process.

Next, the operation will be described. After the winding is completed, the lock mechanism of the mandrel is first released (step K1). Next, the work iron core wound in a cylindrical shape is gripped from the inside and the outside of the cylinder (step K2).
Next, in order to easily remove the work iron core from the mandrel, the outer circumference of the mandrel is reduced (step K3), and the work iron core is removed from the mandrel while being gripped from the inside and the outside of the cylinder (step K4). The extracted work iron core is directly carried to the next process (step K5).

According to this embodiment, when the work iron core is pulled out from the mandrel, the outer diameter of the mandrel is reduced, so that the friction between the mandrel and the work iron core is reduced, and the work can be easily pulled out with a small force. There is. Further, according to this embodiment, since the work is grasped from both the inside and the outside of the cylinder at the time of extraction, the work iron core can be reliably grasped,
This has the effect of reducing the defect rate in the sampling work.

Example 20. 24 shows the invention of claim 21,
That is, it shows an embodiment of the device invention for carrying out the invention of claim 20, and is a mandrel 5 fixed to the main shaft.

And two guide blocks 87 and two bolts 93 connecting them to each other. The attaching / detaching portion 85 is held by the brim portion 87b of the guide block 87 so as to be movable only in the axial direction with respect to the mandrel body 57a. 86a and 86b are holes formed in the expansion / contraction element 86.

Reference numeral 88 designates a slider having a slope on one side, and the slope surface is in contact with the inside slope surface of the expander / contractor 86 and is biased by the spring 91 in the left direction in the figure. It is pushing up in the B direction. At the right end of the elongated hole 88b of the slider 88, a bolt 90 is attached to the mandrel body 57a.

102 is a pin of the device described later.

Next, the operation of this device will be described. The pin 101 advances in the right-hand direction in the figure, and the groove portion 9 of the stopper 95
After passing 5a, the slider 88 is moved to the right against the opposition of the spring 91. After that, by pressing the outer periphery of the wound work iron core inward, the expander / contractor 86 is moved in the direction C (inward in the radial direction) through the work iron core. Due to the movement of the expander / retractor 86 in the C direction, the stopper 95 is C
Since the guide block 87 is pushed in the direction, the portion 95b that prevents the guide block 87 from coming off comes off the stepped portion 87c of the guide block 87. In this state, the work iron core can be removed together with the attaching / detaching portion 85 in the leftward direction in the drawing.

According to this embodiment, not only can the mandrel 57 be made smaller in outer diameter, but also the detachable portion 85 can hold the work iron core from the inside when the work iron core is pulled out, so There is an effect that the work in contact with the inner mandrel is less likely to be damaged when the work iron core is removed.

Example 21. FIG. 25 shows the invention of claim 22,
That is, it shows an embodiment provided with an amorphous sheet extracting device for automatically extracting a work iron core from the mandrel 57 of the invention of claim 21. In the figure, 100

Next, the entire apparatus advances in the right-hand direction in the drawing, and the pin 101 first pushes the slider 88 in FIG. Next, the pin 102 fits into the hole 86a of the expansion / contraction element 86 shown in FIG. Further, the apparatus advances to the right, and the rotation stopper 103 is fitted into the hole 86b of the expansion / contraction element shown in FIG.

Next, the motor 117 rotates to close the claw 100, and the claw 100 holds the work iron core. Further motor 1
17 continues rotating in the same direction for a while to move the claw 100 in the closing direction, and pushes the expander / contractor 86 of FIG. 24 inward through the work iron core. At this time, the slider 111 holding the pin 102 also moves inward. In this state, the work iron core is gripped from the inside and outside of the cylinder. From this state, the entire device moves to the left in the figure, and the work iron core moves together with the attaching / detaching portion 85 of the mandrel 57 to the mandrel body 57.
extracted from a. After that, the entire apparatus rotates around the shaft 119 and conveys the work iron core to the next step.

According to this embodiment, the work of extracting the work iron core after the winding is completed can be automated, and the work is safe and reliable. Further, there is an effect that the work efficiency can be improved.

Example 22. FIG. 26 shows an embodiment of the invention of claims 23 and 24, the back side of which is shown in FIG.
It has the same structure as. Therefore, description of what has been described with reference to FIG. 21 will be omitted. In the figure, 120 is a spindle motor,
Reference numeral 123 is a linear guide attached to the base plate 72 of FIG. 21, and 122 is a slider which is linearly guided through the linear guide 123 and to which the spindle motor 120 is attached. The main shaft motor 120 rotationally drives the main shaft of the mandrel 57 via a speed reducer 121. The slider 122 is connected via a joint 124 to an air cylinder (measure cylinder) 125 which is a measuring means having a linear scale. The measure cylinder 125 is fixed to the base plate 72 via a mounting plate 127.
Reference numeral 128 denotes a control device that calculates the outermost diameter of the work iron core from the data of the major cylinder 125 and controls the motor rotation speed.

Next, the operation will be described. Mandrel 5
When the sheets are sequentially wound around 7, the diameter of the work iron core is gradually increased, and accordingly, the mandrel 57 moves to the right in FIG. The movement amount of the mandrel 57 is read by the linear scale 126 of the measure cylinder 125 connected to the slider 122. The outer diameter of the work iron core can be calculated from the position movement amount of the slider 122.

According to this embodiment, since the outer diameter of the work iron core can be calculated by calculating the outer diameter of the work iron core from the position movement amount of the slider 122, it is possible to accurately obtain the outer diameter of the work iron core with a simple and inexpensive mechanism. The outer diameter of the work iron core can be calculated.

Example 23. FIG. 27 shows an embodiment of the invention of claim 25. In the figure, 135 is a belt drive motor, 120 is a main shaft drive motor, and the other parts are the same as those in FIG. The configuration on the back side of FIG. 27 is the same as that of FIG.

Next, the operation will be described. Mandrel 5
When the sheet 11 is sequentially wound around 7, the diameter of the work iron core is gradually increased, and accordingly, the mandrel 57 moves to the right in FIG. The movement of the mandrel 57 is read by the linear scale 126 of the measure cylinder 125 connected to the slider 122. The outer diameter of the work iron core can be obtained by calculating the outer diameter of the work iron core from the position movement amount of the slider 122. Using the obtained outer diameter value of the work iron core, the control device 128 controls the rotation speed of the motor 120 so that the peripheral speed of the outer circumference of the work iron core becomes equal to the speed of the belt 58.

According to this example, the sheet 1 being wound up
Since 1 can be rotationally driven from the inner side and the outer side in synchronization with each other, there is an effect that the sheets 11 can be wound without slipping each other.

Example 24. FIG. 28 shows a flow chart of the invention of claim 26. In the figure, step L1
Is a step of measuring the spindle position, step L2 is a step of calculating the diameter of the outermost periphery of the work iron core, and step L3 is a step of controlling the spindle rotational speed.

Next, the operation will be described. The spindle position changes according to the change in the diameter of the work iron core, but this position is measured by some means (step L1). Next, using this measured value, the outer diameter of the work iron core is calculated using the relational expression between the spindle position and the outer diameter of the work iron core (step L).
2). Using the value of this outer diameter, the spindle speed is controlled so that the peripheral speed of the outer circumference of the work iron core becomes equal to the belt feed speed (step L3).

According to this embodiment, it becomes possible to measure the spindle position, which is easy to measure, and to control the spindle peripheral speed by using the relational expression between the outer diameter value of the work iron core and the spindle position.

Example 25. FIG. 29 shows an embodiment of the twenty-seventh and twenty-eighth inventions. In the figure, 57, 58, 67 and 68 are the same as those in FIG. Reference numeral 129 is a guide block for the winding portion of the sheet 11, 130 is a tank in which the abrasive material 134 is contained, 131 is its guide tube, and 132 is a valve. Reference numeral 133 is a control device for controlling the opening and closing of the valve 132. When the control device 133 opens the valve 132, the friction material 134 is extruded from the tip end portion of the guide tube 131 into the space between the seats 11 as indicated by reference numeral 134a.

By using this embodiment, it is possible to reliably wind up thousands of sheets 11 without slipping on each other. In this embodiment, the friction material 134 is used to prevent the sheets 11 from slipping with each other, but the same effect can be obtained by using an adhesive instead of the friction material 134.

Example 26. 30 is the same as FIG. 15 described above.

In the figure, the separating plate 12 has a thickness of t, and an edge portion 12a is formed on the front end side 12A thereof. 12b is an edge portion on the upper surface side of the separation plate 12, and 12c is an edge portion on the lower surface side of the separation plate 12. 32A shows the case where the edge portion 12a of the tip portion 12A of the separation plate 12 is located on the lower surface side of the separation plate 12 (t = t ₁ + t ₂ , t ₁ > t ₂ ), and FIG. b) is a case where the edge portion 12a is located at the center of the upper and lower surfaces of the separation plate 12 (t = t ₁ + t ₂ ,
t ₁ = t ₂ ).

Since the separating device configured as described above is configured as described above, the edge portion 1 of the separating plate 12 is
It is possible that the surface pressure at the contact point between the sheet block 2a and the sheet 2a becomes high, and the separation plate 12 is caught by the sheet 11 and cannot smoothly separate the sheets 11 from each other.

FIG. 33 (a) shows a separation plate 1 according to an embodiment of claim 29, which prevents the above from happening.
2 is a cross-sectional view of the second embodiment, and the separating plate 12 in this embodiment has a semicircular shape with a radius R without a sharp edge at its tip portion 12A as shown in the drawing. Here, the radius R is 1/2 of the plate thickness t of the separation plate 12. Separation plate 12 shown
The cross-sectional shape of the front end portion 12A of the sheet does not change along the longitudinal direction of the workpiece and is the same, but as shown in FIG. In FIG. 34, a chip 200 is attached to locally separate the sheet 11 as shown in FIG.

FIG. 35 shows a state in which the chip 200 is inserted between the sheets 11, and FIG. 36 shows a state in which the separation plate 12 is further rotated from the state of FIG. 3 shows that the separation plate 12 is separating the sheet 11. Note that FIG. 37 shows FIG.
FIG. 38 is a plan view of FIG. 6, and FIG. 38 is a cross-sectional view taken along the line nn of the portion A in FIG. 37.

In the case of this embodiment, the sheet separating / aligning operation itself is the same as that of the embodiment 15 shown in FIG. 30, except that the separating plate 12 is further pushed onto the sheet 11 which is locally separated by the chip 200. In the step of separating the entire step 11S, the separation plate 1 having a semicircular tip section
No. 2 does not have the edge portion 12b of the separating plate 12 shown in FIG. 32, but it smoothly abuts on the sheet 11 as shown in FIG. Then, the sheet 11 is separated.

In this embodiment, since the separating plate 12 slides smoothly on the sheet 11, there is no trouble due to damage to the sheet 11, the operating rate of the apparatus is improved, and the work can be completely unmanned.

Example 27. FIG. 33B shows the second embodiment.
6 has a shape different from the sectional shape of the separating plate 12, and the sectional shape of the tip portion 12A of the separating plate 12 is not a semicircular shape, but the curvature radius r ₁ of the tip portion 12A and the curvature radius r of the upper and lower surface shoulder portions. _There is a relation of r ₁ <r ₂ with ₂ . In this embodiment also, as shown in FIG. 30, the chip 200 is attached to the portion that first comes into contact with the seat 11 in a state of being inclined with respect to the seat block in order to locally separate the seats 11 from each other. Has been.

When the separation plate 12 of this embodiment is used,
Since the radius of curvature of the tip portion 12A of the separation plate 12 is smaller than that of the twenty-sixth embodiment, the insertion force in the separation step after inserting the chip 200 is smaller than that of the twenty-sixth embodiment.

Example 28. FIG. 33C shows the tip portion 12A.
Between the radius of curvature r _{1 of} r and the radius of curvature r ₂ of the upper and lower shoulders
₁ is a cross-sectional view of the separation plate 12 having a relation of ₁ > r ₂ and in this embodiment, the separation plate 1 is different from that of the 26th embodiment.
2 has a large radius of curvature of the tip portion 12A, the tip 20
The insertion amount of the separation plate 12 with respect to the separation distance between the sheets 11 in the separation step after insertion of 0 is reduced as compared with that of the twenty-sixth embodiment.

Example 29. 39 shows the positional relationship between the grooves 12d, 12e, 12f of the separation plate 12 and the sheet 11 of the work iron core manufacturing apparatus of FIG. As described above, the separating plate 12 is rotatably supported by the slider 14 by the shaft 13, and is separated from the side surface of the seat block of the seat 11 by the alternate long and short dash line (indicated by 12 ').
After being plunged in, it is rotationally driven to the state shown by the solid line. By this rotation, the grooves 12d, 12 of the separation plate 12 are
e and 12f change from the reference numerals 12d ', 12e', and 12f 'to the state shown by the solid line, and the grooves 12d, 1 of the separating plate 12
The tips of 2e and 12f move in the x direction.

Sheet 11 wound on mandrel 57
Since the diameter gradually increases, the length of the sheet 11 changes from l _i to l _e in the figure as shown in FIG. 39. In this case, the rear end portion 11e of the sheet 11 near aa and bb has a length that fits into the grooves 12e and 12f.
Therefore, when the separation plate 12 is rotated, the groove 1 of the separation plate 12 is
There is a risk that the rear end portion 11e of the sheet 11 is caught by the sheets 2e and 12f and the aligned sheet 11 before winding is displaced in the longitudinal direction of the sheet 11. For this,
As shown in FIG. 40, chamfered portions 12g, 12h, 12i are provided on the shoulders of the grooves 12d, 12e, 12f on the side with which the rear end portion 11e of the work 11 abuts.

In the case of the separating plate 12, the sheet rear end portion 11e of the sheet 11 is used in the separating and aligning operation of the sheet 11.
Although there is always a sheet 11 of a length that hangs in any of the grooves 12d, 12e, 12f of the separation plate, in the separation plate 12 of this embodiment, the grooves 12d, 12 of the separation plate 12 are present.
In both e and 12f, the shoulders on the sheet rear end 11e side are largely chamfered, so that the chip 200 of the separation plate 12 locally separates the sheets 11 and then the separation plate 12 rotates. In the above, the sheet rear end portion 11e is not caught in the grooves 12d, 12e, 12f, and the sheet 11 does not shift in the longitudinal direction.

In the actual winding device, when the belt releasing section 202 is present, the tip 11t of the work group 11G once wound on the mandrel 57 jumps out from the belt releasing section 202 again as shown in FIG. In order to prevent this, a pressing portion 203 as shown in FIG. 42 (a) is pressed against the mandrel 57 side by a spring 204.

In the winding device, the belt releasing unit 2
Since the pressing portion 203 of 02 is a rigid body, the pressing method of the sheet 11 changes due to the change of the outer diameter of the work iron core,
As shown in FIGS. 42 (b) and 42 (c), the pressing method of the pressing portion 203 against the sheet 11 changes due to the change in the outer diameter of the work iron core, and the sheet 11 is wrinkled and cannot be wound neatly. That happens.
