Description

  The present invention divides a wide belt-like sheet such as a plastic film into a plurality of narrow belt-like sheets by a slitter, and distributes it to at least two winding shafts that can hold a plurality of cores by one, In the sheet split winder that winds the distributed strip-shaped sheet around the individual cores held by the winding shaft, the winding core extrapolated to the winding shaft before starting the winding operation was divided. The present invention relates to a core positioning device used for positioning at a holding position on a winding shaft corresponding to a belt-like sheet.

  The above-described core positioning device generally supports a support rod parallel to the winding shaft, a positioning member for each core mounted on the support rod, and supports the support rod at both ends so as to be able to approach and separate from the winding shaft. And a pair of movable arms. In this core positioning device, when positioning the core extrapolated to the winding shaft at the holding position, the support rod is used as the winding shaft so that the positioning member is advanced to a position where it can engage with the end surface of the core on the winding shaft. In this state, each core on the winding shaft is moved along the winding shaft toward each positioning member, and the end surface of the winding core is brought into contact with the side surface of the positioning member. Thereby, the movement of the winding core is prevented, and the winding core is positioned at the holding position on the winding shaft. Further, the arrangement of the positioning members on the support bar can be changed according to the change of the wide strip-like sheet dividing position by the slitter.

  In order to make it possible to change the position of the positioning member, conventionally, as disclosed in, for example, Patent Document 1 below, each positioning member is slidably mounted on the support bar by penetrating the base portion with the support bar. It is. The support bar is fixed to the movable arm so as not to be displaced in the longitudinal direction with respect to the winding shaft at the winding position, and the movable arm is restrained so as not to move in the longitudinal direction of the support bar. The positioning member has a set screw screwed to the base thereof, and can be fixed to the support bar by the set screw.

  However, recently, the material, thickness, width, etc. of the strip-shaped sheet processed in the sheet split winder and the core used are diversified, and various split winding conditions can be achieved by using one sheet split winder. It is required to be able to cope with.

  However, when the material or thickness of the wide belt-like sheet changes, the belt-like sheet may meander or the size of the meander may change. The meandering of this belt-like sheet is from the slitter to the winding axis. It can also occur in the travel route. In this case, the narrow belt-like sheets divided and distributed by the slitter are displaced in the same direction by the same amount in the width direction from the normal positions on the winding shaft corresponding to the divided positions by the slitter. Reach up. Therefore, when meandering of the belt-like sheet is recognized, if the core is positioned at a normal position on the winding shaft, the winding is performed in a state where the belt-like sheet is shifted from the predetermined position on the core in the width direction of the core. It is done. As a result, for example, if the length of the winding core is the same as the width of the divided strip sheet, and the deviation due to meandering is 1 mm, the winding roll formed by winding the divided strip sheet is One end face of the core protrudes from the one end face by 1 mm, and the other end face of the core is retracted by 1 mm from the other end face. Also, if the length of the core is 2 mm longer than the width of the divided strip sheet and the deviation due to meandering is 1 mm, the winding roll protrudes from the one end of the core by 2 mm. The other end face and the other end face of the core are aligned. And such a winding roll will be recognized as inferior goods.

  Therefore, in order to prevent this, it is necessary to position the winding core at a target position that has been corrected in advance in consideration of the deviation of the belt-like sheet. Further, when the material or thickness of the belt-like sheet changes and the meandering size of the belt-like sheet changes, it is necessary to position the winding core at the target position corrected in accordance with the change.

  However, in order to accurately position the core at the corrected target position by the conventional core positioning device, the positioning member on the support bar corresponds to the corrected target position of the core accurately. It is necessary to move and fix the positioning member, and the positioning change operation of the positioning member takes time and is troublesome. In particular, when the number of band-like sheets divided by the slitter is large, the positions of a large number of positioning members must be individually changed, which causes a reduction in the operating rate of the sheet dividing winder.

  In order to facilitate the fine adjustment operation of the position of each positioning member on the support rod, for example, by attaching the position fine adjustment member to each positioning member via a screw in the longitudinal direction of the support rod, Although it is proposed to have a function of finely adjusting the holding position, the apparatus structure becomes complicated and expensive.

What is characterized by being retractable from the other end of the bar.

  According to the present invention, due to the change in the winding conditions such as the material and thickness of the belt-like sheet processed by the sheet split winder, the width of the belt-like sheet by meandering while the belt-like sheet reaches the winding axis. Even in the case where the direction is deviated, it is possible to simply and easily perform the positioning change operation of the positioning member in a short time and to provide a core positioning device having a relatively simple structure. And the operation rate and yield of a sheet | seat division winder can be improved.

It is a side view which shows an example of a sheet | seat division winding apparatus. 1 is a schematic front view of a core positioning device according to an embodiment of the present invention. It is a longitudinal cross-sectional view which shows the right end vicinity of the support rod shown in FIG. It is a side view of a position fine adjustment mechanism. It is a schematic front view of the core positioning device at the time of changing the positioning member positioning. It is a schematic front view of the core positioning device which concerns on the other Example of this invention. It is explanatory drawing of the change aspect of a position fine adjustment mechanism.

  FIG. 1 is a side view showing an example of a sheet split winder to which a core positioning device according to an embodiment of the present invention is applied, and FIG. 2 is a schematic front view of the core positioning device according to an embodiment of the present invention. is there. The sheet split winder divides a wide strip sheet S0 into a plurality of strip strips S by a slitter K and distributes it to two winding shafts 1 and 1, and the distributed strip sheet S is held by the winding shaft 1. The winding roll R of the belt-like sheet S is formed by winding around the individual winding cores C.

  The winding core positioning device 2 is configured so that the supporting rod 3 parallel to the winding shaft 1, the positioning member 4 for each winding core C mounted on the supporting rod 3, and the supporting rod 3 can approach and separate from the winding shaft 1. And a pair of movable arms 5 supported at both ends.

  The winding shaft 1 has known gripping means capable of gripping the inner peripheral surface of the winding core C, and a single winding can penetrate a plurality of winding cores C and hold it at a required position. Further, after the winding core is mounted, it is held at a predetermined position between the left and right machine casings 6 and 6 and is rotationally driven during the winding operation.

  In this embodiment, the winding core C is composed of an inner cylindrical portion c1, an outer cylindrical portion c2, and an arm portion c3 connecting both of them, and a radius (outer diameter) of the outer peripheral surface around which the divided strip sheet S is wound, The difference from the radius (inner diameter) with the inner peripheral surface supported by 1 is large. In this case, when the positioning member 4 is engaged only with a portion near the outer peripheral surface of the end surface of the core C at the time of positioning of the core, the center axis of the core C is inclined with respect to the center axis of the core 1. Since the core C is easily held in the state, in order to prevent this, the positioning member 4 is extended vertically from the base 4b to the longitudinal axis direction of the support bar 3 with the base 4b mounted on the outer peripheral surface of the support bar 3. The arm portion 4a is configured so that the arm portion 4a can also come into contact with the end surface of the core C in the vicinity of the outer peripheral surface of the winding shaft 1, that is, the end surface of the inner cylindrical portion c1.

  Each positioning member 4 has the same size and the same shape. Further, since the support rods 3 are non-rotatably mounted, the same posture can be maintained with respect to the support rods 3. Moreover, it arrange | positions on the support rod 3 so that it may correspond to the holding position of each core C extrapolated to the winding shaft 1. FIG.

  The pair of movable arms 5 is swingable about the fulcrum shaft 7 and cannot move in the longitudinal direction of the fulcrum shaft 7 on a pair of fulcrum shafts 7 provided on the left and right machine casings 6 and parallel to the winding shaft 1. It is attached. The support bar 3 is held at the free end of the movable arm 5. A stay 5a is fixed between the pair of movable arms 5 and 5 to couple them together. The movable arm 5 is connected to the tip of the piston rod of the fluid pressure cylinder device 8, and one end of the cylinder portion of the fluid pressure cylinder device 8 is connected to the machine frame 6. The pair of movable arms 5 can take a standby posture shown by a solid line in FIG. 1 and a positioning posture shown by a two-dot chain line in FIG. When the movable arm 5 is in the standby position, the support bar 3 is separated from the winding shaft 1 and the positioning member 4 is in the retracted position. When the movable arm 5 is in the positioning position, the support bar 3 is moved closer to the winding shaft 1 and the positioning member is positioned. 4 can reach the advance position.

  When the positioning member 4 reaches the advanced position at the time of positioning the winding core, the side surface of the tip portion of the arm portion 4a can be engaged with the end surface of the winding core C, and the positioning member 4 is wound around the winding shaft 1. By preventing the movement of the core C along the winding shaft 1, the winding core C can be positioned at the holding position on the winding shaft 1.

  As shown in FIG. 2, the core positioning is performed so that the positions of a large number of positioning members 4 can be simultaneously finely adjusted in the longitudinal direction of the winding shaft 1 with respect to the winding shaft 1 at a predetermined position. The apparatus 2 includes a guide mechanism 9 that guides the support bar 3 so as to be movable in the longitudinal direction, and a position fine adjustment mechanism 10 that can finely adjust the position of the support bar 3 with respect to the winding shaft 1 in the longitudinal direction.

  The guide mechanism 9 includes hollow cylindrical bushes 11 and 12 fixed to the pair of movable arms 5, respectively, and the outer peripheral surfaces of both end portions 13 and 14 of the support rod 3 are provided on the inner peripheral surfaces of the bushes 11 and 12. It is fitted so that it will be a good relationship.

  In order to arrange each positioning member 4 on the support rod 3 so as to correspond to the holding position of each core C extrapolated to the winding shaft 1, the core positioning device 2 is provided with the positioning member 4 on the support rod 3. A spacer 15 for maintaining the mutual interval at a predetermined interval, a locking member 16 disposed near one end of the support bar 3 (left end in FIG. 2), and the other end of the support bar 3 (FIG. 2 is provided with a nut 17 disposed near the right end).

  The locking member 16 and the spacer 15 are each made of a hollow cylindrical body and are slidably fitted to the outer peripheral surface of the support bar 3. The locking member 16 has a known set screw 18 screwed into a hole provided in the radial direction, and can be fixed to the support bar 3 at a required position by the set screw 18. The spacer 15 is a value obtained by subtracting the length Lb of the base portion 4b of the positioning member from the size L between the end faces on the same side of the adjacent cores C arranged at positions corresponding to the divided strip sheets S. Has a length Ls equal to.

  The positioning member 4 and the spacer 15 on the support bar 3 are arranged and mounted on the support bar 3 so that the spacers 15 are arranged between the adjacent positioning members 4 and 4, and then the positioning member 4 and the spacer 15. The row is fastened and fixed by a locking member 16 and a nut 17.

  In the case of the embodiment shown in FIG. 2, since the length of the female screw with which the nut 17 is screwed is short, the range in which the nut 17 can be tightened is narrow. Therefore, a hollow cylindrical fastening collar 19 having an appropriate length is interposed between the nut 17 and the rightmost positioning member 4. Therefore, the locking member 16 and the nut 17 are indirectly clamped with the row of the positioning member 4 and the spacer 15 interposed therebetween. If necessary, it may be clamped and fixed directly between the locking member 16 and the nut 17 without using the clamping collar 19, or tightened between the positioning member 4 on the left end and the locking member 16. An attaching collar may be interposed.

  The base portion 4 b of the positioning member 4, the spacer 15, the locking member 16, and the fastening collar 19 are each formed so that both end faces thereof are perpendicular to the central axis of the support bar 3.

  3 and 4, the position fine adjustment mechanism 10 has an operation unit 20 that receives a rotational driving force for moving the support bar 3 in the longitudinal direction, and supports the rotational driving force received by the operation unit 20. It can be converted into a driving force that is reduced in the longitudinal direction of the rod 3 and applied to the support rod 3. And in order to comprise in that way, the screw rod 21 screwed concentrically with the center axis line of this support rod 3 is provided in the right end part 14 of the support rod 3. As shown in FIG. The screw rod 21 has a shaft portion 22 on the rear side of the male screw forming portion, and the shaft portion 22 penetrates the holding member 23 fixed to the movable arm 5 so as to be slidable. On the other hand, the operation unit 20 is composed of a rotary knob and has a spindle 24 that rotates integrally with the rotary knob. The spindle 24 is rotatably held by the movable arm 5. A bevel gear 25 is fixed to the tip of the spindle 24, and the bevel gear 25 meshes with a bevel gear 26 fixed to the shaft portion 22 of the screw rod 21. Since the screw rod 21 is restrained in the axial direction with the holding member 23 sandwiched between the shoulder of the shaft portion 22 and the end face of the boss portion of the bevel gear 26, the screw rod 21 can be rotated by the movable arm 5 and restrained in the axial direction. Being held. A key groove 27 extending in parallel to the axis is formed on the outer peripheral surface of the bush 12, and one end of a key member 28 is slidably fitted in the key groove 27 in the longitudinal direction. Is fixed to the right end portion 14 of the support bar 3 by a bolt 29, so that the right end portion 14 of the support bar 3 is not rotatable with respect to the movable arm 5. Therefore, when the operation unit 20 receives a rotational driving force for moving the support rod 3 and rotates, the rotation is transmitted to the screw rod 21 and the screw rod 21 rotates, and this rotational motion forms a female screw. The right end 14 of a certain support bar 3 moves in the axial direction. Further, the moving speed of the support rod 3 in the axial direction is reduced according to the lead angle of the screw formed on the screw rod 21. Thereby, the fine adjustment of the position of the support bar 3 becomes accurate and easy. Further, in order to be able to grasp the amount of movement of the support rod 3 with respect to the winding shaft 1 during fine adjustment of the position, the operation unit 20 counts the number of rotations of the operation unit 20 with respect to the movable arm 5 and indicates the total number of rotations as a pointer. Is provided with an indicator (not shown).

  The right end 14 of the support bar 3 is made of a short bar member, and is separably fixed to the right end of the main bar 30 of the support bar 3. The right end portion 14 of the support bar 3 is provided with an engaging portion 14a formed with a hole 31 for receiving the right end of the main body rod member 30 on the main body rod member 30 side, and on the outer peripheral surface of the engaging portion 14a. A radial hole 32 in which a female screw is formed is provided, and a bolt 33 with a knob is screwed into the hole 32. On the other hand, a hole 34 is formed in the distal end portion of the main body bar member 30 in the radial direction from the outer peripheral surface thereof. Then, the right end of the main body bar member 30 is fitted into the hole 31 of the engaging portion 14a, and the tip 33a of the bolt 33 formed into a columnar shape is fitted into the hole 34 of the main body bar member 30, thereby The end portion 14 is fixed to the right end portion of the main body bar member 30. Further, by pulling out the tip 33 a of the bolt 33 from the hole 34 at the right end of the main body bar member 30, the end 14 of the support bar 3 can be separated from the main body bar member 30. The nut 17 is screwed to a female screw formed on the outer peripheral surface of the engaging portion 14 a of the right end portion 14 of the support bar 3. The positioning member 4 and the spacer 15 are slidably penetrated by the main body bar member 30.

  The movable arm 5 is provided with a bolt 35 with a handle for fixing the spindle 24 thereto. The bolt 35 with a handle can be used to prevent inadvertent movement after fine adjustment of the position of the support bar 3 because the screw bar 21 can be prevented from rotating when the bolt 35 with a handle is tightened.

  In order to make the positioning member 4 non-rotatable with respect to the support rod 3, a set screw 36 is screwed in the radial direction on the base portion 4 b of the positioning member 4, and a cylindrical portion 37 formed at the tip of the set screw 36 is provided. The sliding key is slidably fitted in a key groove 38 formed on the outer peripheral surface of the main body bar member 30.

  As shown in FIG. 5, when the main body bar member 30 and the right end 14 of the support bar 3 are separated, the length corresponding to the larger one of the widths of the positioning member 4 or the setting spacer 15 is greater than or equal to the length. In addition, the main body bar member 30 can be retracted from the right end 14 of the support bar 3.

  In the slitter winder, when the strip sheet splitting specification by the slitter K is changed, the arrangement of the cores C on the winding shaft 1 is changed. Therefore, in the above-described core positioning apparatus 2, the split strip sheet S is scheduled. The arrangement of the positioning member 4 on the support bar 3 is changed so that the winding core C is arranged at the supplied position. Thereafter, in order to position the core with the core positioning device 2, first, the winding operation of the slitter winder is started at a low speed to grasp the meandering state of the divided strip sheet S. If the support position of the core C is deviated with respect to the supply position of the strip-shaped sheet S divided at that time, the support bar 3 is moved in the longitudinal direction by the position fine adjustment mechanism 10 in such a direction that the deviation is eliminated. Move and finely adjust the position of the support bar 3. As a result, the positions of all the positioning members 4 on the support rod 3 with respect to the winding shaft 1 are corrected simultaneously. In order to move the support bar 3 by the position fine adjustment mechanism 10, the operator manually applies a rotational driving force to the operation unit 20, and rotates the operation unit 20 by a necessary number of rotations in a necessary direction. At this time, if the operation is performed while looking at the indicator provided in the operation unit 20, the position of the positioning member 4 can be finely adjusted easily and accurately.

  In the above-described winding core positioning device 2, in order to change the arrangement of the positioning member 4 on the support bar 3, an operator turns the bolt 33 with a knob to move the right end 14 of the support bar 3 from the main body bar member 30. After the separation, the main body bar member 30 is retracted from the right end 14 of the support bar 3 as shown in FIG. Is made larger than the width of the positioning member 4 or the width of the spacer 15, and then the positioning member 4 and the spacer 15 that are no longer needed on the main body bar member 30 are extracted from the tip of the main body bar member 30.

  Next, a spacer 15 having an appropriate width is selected so that the positioning member 4 is arranged on the support rod 3 in accordance with the arrangement of the core C that is newly required on the winding shaft 1, and the spacer 15 and the positioning are positioned. The members 4 are mounted on the main body bar member 30 from the front end of the main body bar member 30 in the required order. At this time, the position of the engaging member 16 is adjusted as necessary, or a fastening collar 19 having an appropriate width is selected and mounted.

  When all the necessary positioning members 15 and spacers 15 are mounted, the main body bar member 30 is moved toward the right end 14 of the support bar 3, and the front end of the main body bar member 30 is moved into the hole as shown in FIG. 31 and is fixed to the right end 14 of the support bar 3 and the main body bar member 30. Thereafter, the nut 17 is turned and the row of the positioning member 4 and the spacer 15 is fastened and fixed by the locking member 16 and the nut 17. In the case of this embodiment, it is convenient because the end portion 14 can be separated from and coupled to the main body rod member 30 without removing the nut 17 from the right end portion 14 of the support bar.

  FIG. 6 is a schematic front view of a winding core positioning device according to another embodiment of the present invention. In FIG. 6, both ends of the support bar 3 are fixed to a pair of movable arms 5 and 5, and the pair of movable arms 5 and 5 are fixed to a pair of support bodies 39 and 39 in parallel to the winding shaft 7. 7 is attached. A pair of movable arms 5 is connected to the tip of a piston rod of a fluid pressure cylinder device 8, and one end of a cylinder portion of the fluid pressure cylinder device 8 is connected to a support 39. The support 39 is slidably mounted on a rail 40 fixed to the machine casing 6 and parallel to the support bar 3. Accordingly, the support 39 is guided by the rail 40 in parallel with the longitudinal direction of the support bar 3, and the support bar 3 on the support 39 is indirectly guided by the rail 40 in the longitudinal direction. Therefore, in this embodiment, the left and right rails 40, 40 serve as a guide mechanism 9 for directly or indirectly guiding the support bar 3 so as to be movable in the longitudinal direction. The fine position adjustment mechanism 10 has a handle 20 that is manually operated. The handle 20 is fixed to one end of a spindle 42 rotatably held by a bracket 41, and the bracket 41 is fixed to a support body 39. A pinion 43 is fixed to the other end of the spindle 42, and this pinion 43 meshes with a rack 44 fixed to the machine frame 6 in parallel with the right rail 40. The diameter of the handle 20 is larger than the pitch circle diameter of the pinion 43. When the handle 20 is turned, the pinion 43 moves on the rack 44, and the support bar 3 together with the support body 39 is guided by the rail 40 and moved accordingly.

  In the present invention, the embodiment is not limited to the above-described embodiment, and can be variously changed as necessary. For example, as shown in FIG. 3, the position fine adjustment mechanism 10 is screwed into the end portion 14 of the support bar 3 concentrically with the central axis of the support bar 3 and is rotatable by the movable arm 5 in the axial direction. 7 is not limited to the restraint and holding screw rod 21 and means 24, 25, 26 for transmitting the rotation of the operation unit 20 to the screw rod 21, but as shown in FIG. A fixed screw rod 21, a female screw body 45 screwed to the screw rod 21, and a holding body 46 fixed to the movable arm 5 that holds the female screw body 45 in a rotatable and axially constrained manner. Alternatively, the female screw body 45 may be used as an operation portion, or the female screw body 45 may be provided with means for transmitting the rotation of the operation portion. 6, instead of fixing the rack 44 to the machine frame 6, the rack 41 is fixed to the support body 39 and the bracket 41 for holding the spindle 42 for holding the handle 20 and the pinion 43 is provided on the machine frame 6. May be good. Alternatively, a rack may be formed at the end of the support bar, and a pinion or an operation unit that meshes with the rack may be provided at a predetermined position on the movable arm. Also, instead of fixing the fulcrum shaft to which the movable arm is attached to the machine frame, the support rod can be moved in the longitudinal direction by attaching it to the bush fixed to the machine frame so that it can slide in the longitudinal direction of the fulcrum shaft. You may make it guide so that a movement to a direction is possible.
