Description

TECHNICAL FIELD

[0001] The present application relates to a wire arranging device that winds a wire or the like around a winding drum, and more particularly to a wire arranging device that detects the position of flanges provided at both ends of the winding drum and uniformly winds the wire around the winding drum while reciprocating the wire. BACKGROUND

[0002] Conventionally, when a wire is fed or retracted with respect to a winding drum, a wire arranging device is generally used.

[0003] The wire arranging device has a wire arranging pulley provided in the vicinity of the winding drum around which the wire is wound, and a moving mechanism for moving the wire arranging pulley in the direction of the rotation axis of the winding drum, and the wire is uniformly wound by moving the wire arranging pulley in the direction of the rotation axis of the winding drum.

[0004] However, in such a wire arranging device, as a technique for detecting the position of flanges provided at both ends of the winding drum and reciprocating the wire arranging pulley in accordance with the position of the flanges, the structure described in Patent Document 1 is proposed.

[0005] The wire arranging device has an optical sensor provided on the wire arranging pulley, and the position of the flanges is detected using the optical sensor when the wire arranging pulley is reciprocated, thereby reciprocating the wire arranging pulley.

[0006]

Patent Document 1

[0007] However, the structure of such a wire arranging device has the following problems.

[0008] That is, as shown in Patent Document 1, when the position of the flanges is detected using the optical sensor, the position of the flanges cannot be accurately detected due to the influence of slurry at times. In addition, if the distance between the optical sensor and the winding drum is long, the optical axis is sometimes deviated. Furthermore, if vibration is generated when the wire arranging pulley is turned back, the position of the flanges cannot be accurately detected at times.

[0009] On the contrary, although a physical contact sensor can be installed on the wire arranging pulley, and the position of the flanges can be detected by bringing a contact provided on the contact sensor into contact with the flanges, in this method, the contact is present in the vicinity of the wire, and thus the wire can come into contact with the contact. In addition, when the wire is broken, the broken wire can hit the contact, and the contact can be damaged.

[0010] Therefore, the present application is proposed in view of the above-described problem, and aims to provide a wire arranging device in which a contact sensor does not interfere with the movement of a wire or the like when the contact sensor is used to detect the position of a flange of a wire arranging pulley. Means for solving the problem

[0011] That is, the present application is proposed in view of the above-described problem, and aims to provide a wire arranging device in which a contact sensor does not interfere with the movement of a wire or the like when the contact sensor is used to detect the position of a flange of a wire arranging pulley.

[0012] If so configured, the contact sensor can be separated from the wire when the wire is fed or retracted, and thus the possibility of contact between the wire and the contact sensor can be reduced.

[0013] In addition, in such an application, when the second moving mechanism is provided, a swing mechanism that swings and rotates the wire arranging pulley in a direction that intersects the rotation axis of the winding drum is used.

[0014] If so configured, the wire arranging pulley can be moved simply without using a large structure as compared with the case where a linear movement mechanism or the like is used.

[0015] Further, when the position of the flange is detected, the contact sensor is used to detect the position of the flange and store the detected position of the flange, and when the wire is not fed or retracted with respect to the winding drum, the contact is moved to a position that abuts against the flange of the winding drum, and the wire arranging pulley is reciprocally moved within the range of the stored positions of the flanges in the first moving mechanism.

[0016] If so configured, the contact of the contact sensor is not abutted every time the wire arranging pulley is reciprocally moved, and the wire arranging pulley can be moved with an appropriate width of the winding drum using the stored information, and thus the possibility of wire breakage is reduced.

[0017] In addition, when the contact of the contact sensor is provided, the feeding and retraction position of the wire arranging pulley is provided along the wire direction of the wire.

[0018] If so, the position of the contact can be made to coincide with the position of the wire, so the wire guide pulley can be accurately turned back at the position of the flange.

[0019] Further, when the contact sensor is provided, it is mounted on a bracket that holds the wire guide pulley.

[0020] If so, the contact sensor can be moved between the contact position and the non-contact position of the flange using a mechanism that swings the wire guide pulley, so the device can be simplified and the cost can be reduced. Effects of Invention

[0021] According to the present application, when the wire is fed or withdrawn, the contact of the contact sensor can be separated from the wire, so the possibility of the wire contacting the contact of the contact sensor can be reduced. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0023] Hereinafter, an embodiment of the present application will be described with reference to the drawings.

[0024] A spool cutting device 1 to which the wire guide device 4 in this embodiment is applied is constructed as shown in Figure 1 , so as to have a wire 3 that cuts a spool 8 of silicon, a reel 2 on which the wire 3 is wound, a wire guide device 4 that uniformly winds the wire 3 on the reel 2, a cutting section 7 that cuts the spool 8 using the above-mentioned wire 3, and the like. Further, as shown in Figures 2 to 6 , it is formed so that a contact sensor 5 that abuts against flanges 21 provided at both ends of the above-mentioned reel 2 is provided on the wire guide device 4, at the time of initial setting, as shown in Figure 6 , the contact 51 of the contact sensor 5 is positioned at the abutting region of the flanges 21, and is moved left and right (in the state of Figure 2 and Figure 3 ), the position of the flanges 21 is detected and stored in a storage section 91, and at the time of cutting the spool 8, as shown in Figure 4、 Figure 5 As shown in FIG. 1, the contact sensor 5 is configured to retreat the contact 51 of the contact sensor 5 to the non-contact region of the flange 21. Also, by thus arranging the contact 51 at a position away from the wire 3, the possibility of the wire 3 contacting the contact 51 is reduced. Hereinafter, the ingot cutting device 1 and the wire guide device 4 in the present embodiment will be described in detail.

[0025] First, the roll 2 provided in the ingot cutting device 1 is a member having flanges 21 at both ends in the direction along the rotation axis, and is formed so as to wind the wire 3 between the flanges 21. Also, the wire 3 is fed out or taken in with a certain tension using a motor provided on the rotation axis of the roll 2.

[0026] The wire guide device 4 provided adjacent to the roll 2 is configured as shown in FIG. 2, and has a wire guide pulley 41 and a bracket 43 that holds the wire guide pulley 41. Figure 2 、 Figure 3 As shown in FIG. 3, the wire guide device 4 is configured to have a moving mechanism 61 that has a slide rail 62 that moves the wire guide pulley 41 in the direction along the rotation axis of the roll 2. The moving mechanism 61 is controlled by a control section 92 so as to make the wire guide pulley 41 turn back at the position of the flange 21 stored in a storage section 91. Here, as shown in FIG. 4, the rotation axis of the wire guide pulley 41 is provided so as to cross the rotation axis of the roll 2, and the wire 3 that is fed out or taken in with respect to the roll 2 is directed in the direction along the rotation axis of the roll 2. Also, the roll 2 and the wire guide device 4 thus provided are formed as shown in FIG. 5, and are provided with two places on the wire feeding-out side and the wire taking-in side across the cutting section 7, so as to move the wire 3 back and forth between the roll 2 on one side and the roll 2 on the other side, and perform cutting processing. Figure 5 Figure 1 As shown in FIG. 6, the cutting section 7 provided in the middle of the path of the wire 3 is a member that can cut the ingot 8 using the wire 3, and is configured so that the wire 3 is wound around the left and right guide rollers 71, and is pressed against the ingot 8 with a prescribed pressure, so as to be able to cut the ingot 8 to the thickness of the gap of the wire 3.

[0027] The cutting section 7 provided in the middle of the path of the wire 3 is a member that can cut the ingot 8 using the wire 3, and is configured so that the wire 3 is wound around the left and right guide rollers 71, and is pressed against the ingot 8 with a prescribed pressure, so as to be able to cut the ingot 8 to the thickness of the gap of the wire 3. Figure 1 Also, in such a structure, the contact sensor 5 that detects the turning-back position of the wire guide pulley 41 is provided in the present embodiment (refer to FIG. 7 and the like).

[0028] Figure 2 The contact sensor 5 is configured so that the contact 51 in the length direction comes into contact with the flange 21, and is able to detect the position of the flange 21. Also, the storage section 91 stores the position of the flange 21 detected, and the control section 92 controls the moving mechanism 61 so as to make the wire guide pulley 41 turn back at the position.

[0029] The contact sensor 5 is installed on the bracket 43 that holds the wire guide pulley 41. As shown in FIG. 8, the contact 51 of the contact sensor 5 is provided so as to be able to detect the position of the flange 21 of the roll 2.

[0030] The contact sensor 5 is installed on the bracket 43 that holds the wire guide pulley 41. As shown in FIG. 8, the contact 51 of the contact sensor 5 is provided so as to be able to detect the position of the flange 21 of the roll 2. Figure 2 、 Figure 3 ​​As shown, the contact sensor 5 is disposed in the direction of the wire 3 from the wire feeder pulley 41 at the time of installation of the bracket 43. Also, by disposing the contact sensor 5 in this way, the position of the wire 3 wound around the reel 2 is made to coincide with the position of the contact 51, so that the return position of the wire feeder pulley 41 can be accurately detected.

[0031] The bracket 43 for mounting the contact sensor 5 is disposed to rotate in the direction along the rotational axis of the wire feeder pulley 41 via a swing mechanism 63. As shown, Figure 5 The swing mechanism 63 is formed so that the groove 42 of the wire feeder pulley 41 is in the direction of the wire 3 from the reel 2, and is configured to swing using a motor disposed inside, with the swing axis 44 (refer to Figure 2 , Figure 3 ) as the center. In addition, when the groove 42 of the wire feeder pulley 41 is made to coincide with the wire direction of the wire 3, for example, it can be formed so as to calculate the winding diameter of the wire 3 wound around the reel 2 using a sensor not shown that measures the distance after the wire 3 is fed out, and make the groove 42 of the wire feeder pulley 41 face the position along the outer diameter. Also, when the wire feeder pulley 41 is swung in this way, in order to be able to swing the wire feeder pulley 41 with a small force, a balancer 45 having the same mass is provided on the opposite side of the swing axis 44.

[0032] As shown, Figure 5 When the ingot 8 is cut, the contact 51 of the contact sensor 5 is retracted to a position that does not abut against the flange 21. With regard to the position of the contact 51, when the minimum angle and the maximum angle of the direction of the groove 42 of the wire feeder pulley 41 when the wire is fed out to the reel 2 from the horizontal plane are set as Dl, D2, respectively, the contact 51 of the contact sensor 5 is made to face a position that deviates from these angles. At this time, although it is possible to make the contact 51 be at an angle smaller than the minimum angle Dl and dispose the contact sensor 5 on the near side of the wire feeder pulley 41, if the contact sensor 5 is made to face such a position, the contact 51 becomes an obstacle at the time of installation of the wire feeder pulley 41. Therefore, here the contact 51 is disposed on the inner side of the wire feeder pulley 41 and at a position greater than the maximum angle D2 when the wire 3 is fed out. Also, by disposing the contact 51 at such a position, the distance of the wire 3 from the contact 51 is pulled apart, and when it is necessary to detect the position of the flange 21, as shown, Figure 6 the bracket 43 is swung using the swing mechanism 63, the contact 51 is moved to the abuttable region of the flange 21, and the contact 51 is reciprocally moved using the moving mechanism 61 (Figs. 6 and 7). Figure 2 and Figure 3the flanges 21, and stores the positions in the storage section 91. Also, after storing the positions of the flanges 21 in this way, the contact 51 of the contact sensor 5 is swung to a position deviating from the maximum angle at which the wire guide pulley 41 feeds and withdraws the wire 3 (a state in which the contact 51 of the contact sensor 5 is in the non-contact region of the flanges 21), and the wire 3 is separated from the contact 51 when feeding and withdrawing the wire 3. Figure 4 and Figure 5 the wire 3 is separated from the contact 51 when feeding and withdrawing the wire 3.

[0033] Next, the method of using the ingot cutting device 1 configured in this way will be described.

[0034] First, when cutting the ingot 8 using the wire 3, the empty reel 2 on the recovery side (a reel 2 on which the wire 3 is not wound) is installed on the rotating shaft. At this time, as shown in FIG. 6, the contact 51 of the contact sensor 5 is retracted to the non-contact region of the flanges 21 in advance. Figure 5

[0035] Also, in the state in which the reel 2 is installed on the rotating shaft, the contact 51 of the contact sensor 5 is swung to the contact region of the flanges 21 using the swinging mechanism 63 as shown in FIG. 7, and the wire guide pulley 41 is reciprocally moved left and right using the moving mechanism 61 in this state as shown in FIG. 8. Figure 6 Figure 2 Figure 3

[0036] Thus, the contact 51 of the contact sensor 5 comes into contact with the flanges 21, whereby the positions of the flanges 21 left and right are detected. Also, the positions of the flanges 21 detected in this way are stored in the storage section 91.

[0037] Next, in the state in which the positions of the flanges 21 are stored, the wire 3 is fed in a state in which a certain tension is applied, and the ingot 8 is cut.

[0038] At this time, as the wire 3 is withdrawn, the winding diameter on the reel 2 gradually decreases, and on the other hand, the winding diameter of the wire 3 on the opposite side gradually increases. At this time, in accordance with this change in winding diameter, the wire guide pulley 41 is swung using the swinging mechanism 63 so that the groove 42 of the wire guide pulley 41 is directed in a direction corresponding to the winding diameter of the wire 3. Also, in this state, the wire guide pulley 41 is reciprocally moved using the moving mechanism 61. At this time, the wire guide pulley 41 is controlled to reciprocate between the positions of the flanges 21 stored in the storage section 91.

[0039] Also, the ingot 8 is cut while the wire 3 is reciprocally moved.

[0040] ​​​​Thus, according to the above-described embodiment, a wire arranging device 4 is provided with: a bobbin 2 having flanges 21 at both ends and winding a wire 3 between the flanges 21; a wire arranging pulley 41 that guides the wire 3 that is fed from and withdrawn to the bobbin 2; a moving mechanism 61 that moves the wire arranging pulley 41 in the direction of the rotation axis of the bobbin 2; a contact sensor 5 having a contact 51 that abuts against the flanges 21 of the bobbin 2, in the wire arranging device 4, a swinging mechanism 63 that swings the contact 51 of the contact sensor 5 in the direction that crosses the rotation axis of the bobbin 2 is provided, and a control section 92 that, when the wire 3 is fed on and withdrawn from the wire arranging pulley 41, retracts the contact 51 to the outside of the flanges 21 of the bobbin 2, and when the wire 3 is not fed with respect to the bobbin 2, moves the contact 51 to the position that abuts against the flanges 21 of the bobbin 2, and thus, when the wire 3 is fed, the contact 51 of the contact sensor 5 can be moved away from the wire. Thus, the possibility of the wire 3 contacting the contact 51 of the contact sensor 5 can be reduced.

[0041] Note that the present application is not limited to the above-described embodiment and can be implemented in various ways.

[0042] For example, in the above-described embodiment, the rotation axis of the wire arranging pulley 41 is provided to cross the rotation axis of the bobbin 2, but it can be configured so that the rotation axis of the wire arranging pulley 41 and the rotation axis of the bobbin 2 are oriented in the same direction and the wire 3 is advanced.

[0043] Further, in the above-described embodiment, the wire arranging pulley 41 is swung with the swinging axis 44 as the center, but it can be moved to a position corresponding to the winding diameter of the wire 3 by linear movement.

[0044] Furthermore, in the above-described embodiment, the contact sensor 5 is mounted on the bracket 43 of the wire arranging pulley 41 and swung and rotated integrally with the wire arranging pulley 41, but it can be swung and rotated or moved linearly independently of the wire arranging pulley 41.

[0045] Further, in the above-described embodiment, the spindle cutting device 1 that cuts the spindle 8 is described as an example, but the present application can be applied to a device that feeds yarn from a spool having flanges or the like, in addition to this. Explanation of Symbols
