Description

  The present invention relates to a winding plate (winding collar) used by being mounted on a friction winding shaft.

  Conventionally, a winding device configured to slit a wide belt-like sheet such as a metal strip such as a cold-rolled steel plate, a plastic film, paper, or a metal foil into a predetermined width and wind it around a friction winding shaft all at once. Are known.

  Usually, the friction winding shaft in this winding device includes at least a rotating shaft connected to a driving source of the winding device and driven to rotate, and a winding that is attached to the outer peripheral surface of the rotating shaft and winds a belt-like sheet. A plurality of winding plates that hold the core (winding core) from the inner peripheral side, and a friction clutch mechanism that transmits the rotational force of the rotating shaft to the winding plate so as to be capable of slip rotation, such as a fluid mechanism A pressing force is applied to the friction clutch mechanism via the belt, and a rotational force corresponding to the frictional force is distributed and transmitted to each winding plate, and each belt-like sheet slit by this rotational force is wound around each core with an independent torque. Is configured to take.

  Conventionally, as a winding plate of such a friction winding shaft, a winding plate 10 as shown in a plan view in FIG. That is, the winding plate 10 is provided with fan-shaped drum blades 14 (three in this embodiment) supported by bolts 12 and taper pins 13 on the side of an annular plate-shaped winding plate main body 11. When the bolt 12 is tightened, the inclined surface of the taper pin 13 provided on the drum blade 14 slides along the wall surface of the guide hole 15 provided on the winding plate body 11, and the drum blade 14 is moved accordingly. As shown in the figure, it protrudes from the outer periphery of the take-up plate main body 11, and the core C is pressed from the inner diameter side to be fixed and held on the take-up plate 10. On the contrary, when the bolt 15 is loosened, the drum blade 14 moves to the center side of the winding plate main body 11, whereby the winding core C can be removed from the winding plate 10.

  Conventionally, as similar to the above-described winding plate, a pair of left and right fan-shaped wings are arranged on a circular plate-shaped winding plate body, and one end side of each wing is attached to the winding plate body by a pin. While supported rotatably, the other end side is connected by wing expansion / contraction adjustment bolts. By tightening or loosening the wing expansion / contraction adjustment bolts, each wing is expanded and contracted in the radial direction of the winding plate with the pin as a fulcrum. In addition, a winding plate is also known in which the core is fixed, held, and removed.

  However, in any of these winding plates, when winding the belt-like sheet S, first, the winding core C is mounted on the winding plate 10, and the bolt 12 is tightened with a tool such as a spanner to fix the winding core C. It is necessary to fix and hold on the outer periphery of the take-up plate 10, and to insert and set the take-up plate 10 through the take-up shaft in a state where the take-up plate 10 is sandwiched between a friction plate and a spacer. In addition, after winding the belt-like sheet S around the winding core C, the winding plate 10 is once pulled out of the winding shaft, and the bolt 12 is loosened to remove the winding core C from the winding plate 10 to prepare for the next winding. Since it was necessary to set it on the take-up shaft again, the take-up work took a lot of time and effort, and there was a problem in terms of work efficiency.

  On the other hand, Patent Document 2 proposes a winding plate 20 as shown in a plan sectional view in FIG. That is, the winding plate 20 is disposed on the upper surface of each stepped portion 21 of the ring 22 so as to be capable of rolling, with the ring 22 having an inclined stepped portion 21 formed at intervals in the circumferential direction. When the rolling element 23 and the annular ring 24 having an opening Q provided in a part in the circumferential direction and inscribed in contact with the outer circumference of the rolling element 23 are fixed to the annular ring 24 during winding, With the ring 22 fixed, the annular ring 24 is manually rotated from above the core C in the clockwise direction indicated by the arrow, and the rolling element 23 is moved along the inclined surface of the stepped portion 21 by frictional force. The annular ring 24 is expanded by expanding the portion Q. When the winding core C is removed from the annular ring 24 after winding, the object is achieved by rotating the annular ring 24 in the opposite direction, that is, counterclockwise.

  However, this winding plate 20 facilitates the work of attaching and detaching the winding core C to and from the annular ring 24. Therefore, the working efficiency is improved as compared with the winding plate 10 described above. 23, it is a method of pressing and fixing from the inner side to the winding plate 10 so that the axial direction of the winding core C is perpendicular to the diameter direction of the winding plate 20, and the winding plate 20 and the winding core C Therefore, it is necessary to adjust the movement of the rolling element 23 so as to be coaxial with each other, and this adjustment work is extremely complicated and difficult.

  Further, since the annular ring 24 is provided with the opening Q in a part in the circumferential direction, the inner side of the core C cannot be pressed by the annular ring 24 with a uniform force in the radial direction, For this reason, the coupling force between the winding core C and the winding plate 20 cannot be sufficiently obtained, and when a large tension is required at the time of winding, there is a possibility that slip occurs between them. In particular, when a different size of the core C is used, there is a problem that rotational constriction occurs during winding because the concentric setting with the winding shaft cannot be performed.

Furthermore, since both of the above-described conventional winding plates 10 and 20 are for winding the belt-like sheet S by fixing and holding the winding core C on the outer periphery thereof, the winding plate is not used. The belt-like sheet S could not be wound directly around the outer periphery of itself.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to efficiently perform a winding preparation work and a post-processing work of a belt-like sheet, and at the time of winding. Provided is a friction take-up shaft take-up plate that can firmly fix a take-up core without causing slippage between the take-up core and can directly take up a belt-like sheet without using a roll core. There is to do.

A friction take-up shaft comprising a plurality of take-up plates and a friction clutch mechanism for transmitting the rotational force of the rotary shaft to the take-up plate in a slip-rotatable manner. The take-up plate is mounted on the rotary shaft. An outer ring is provided separately from the inner ring on the outer peripheral side of the inner ring rotated via the friction clutch mechanism, and the inner ring has a spur gear having teeth arranged on a concentric circle and a rotational phase angle of the spur gear. A guide member for restriction is provided, and a plurality of arc-shaped drum blades for fixing and holding the winding core are arranged at equal intervals on the outer peripheral side of the outer ring, and the adjacent sides of the drum blades are tension springs. Connect and radiate the drum blade from the axis And a guide member for restricting the amount of movement is provided, and between the gear and the drum blade, one end side meshes with the spur gear and the other end slides on the inner peripheral surface of the drum blade. An eccentric cam with a moving gear is provided so as to be rotatable around a fixed pin, and the drum blade is expanded and contracted by the relative rotation of the inner ring and the outer ring via the spur gear and the eccentric cam with the gear. This is achieved by providing a winding plate of a friction winding shaft.

  Further, the above object of the present invention is that the inner ring and the outer ring are formed by connecting a pair of left and right inner ring side plates and outer ring side plates to each other by a connecting member, and the spur gear is provided with the gears inside the inner ring side plate. The eccentric cam and the drum blade are provided inside the outer ring side plate, respectively, and can be more effectively achieved by providing the winding plate of the friction winding shaft according to claim 2. The

  As described above, according to the winding plate of the friction winding shaft according to the present invention, the drum blade is centered through the spur gear and the eccentric cam with the gear by the rotational movement of the inner ring, that is, by the relative rotation between the inner ring and the outer ring. The drum blades can be expanded and contracted without using any tools, and even when using different-sized cores, they can be set concentrically with the winding shaft. Since the take-up shaft and the take-up plate are constantly rotating relative to each other during the take-up operation, use this slip rotation to set the rotation direction of the inner ring relative to the outer ring so that it always expands. In addition, after winding the belt-like sheet, it is possible to pull out only the take-up shaft by keeping the take-up product fixed and rotating the take-up shaft in the anti-drive direction. Therefore, according to the winding board which concerns on this invention, the winding preparation work and post-processing work of a strip | belt-shaped sheet | seat can be performed efficiently. In addition, the winding core can be firmly fixed without causing any slip between the winding core during winding, and the belt-like sheet can be directly wound on the outer periphery of the winding plate without using the winding core.

  The winding plate 110 is attached to the rotating shaft 101 and is rotated via the friction clutch mechanism described above, an outer ring 112 provided separately on the outer peripheral side of the inner ring 111, and a concentric circle of the outer ring 112. A spur gear 113 provided inside the outer ring 112, a guide member 114 that regulates the rotational phase angle of the spur gear 113, and an outer peripheral side of the outer ring 112 arranged at equal intervals. The fan-shaped drum blade 115 that fixes and holds the core C, the tension spring 116 that is connected to the adjacent sides of the drum blade 115 and biases them, and the drum blade 115 moves in the radial direction from the axis O. Between the spur gear 113 inside the outer ring 112 and the drum blade 115 so as to be rotatable around the fixed pin 118, and one end side is flat. A geared eccentric cam 119 that meshes with the wheel 113 and slides on the inner peripheral surface of the drum blade 115 on the other end side. Each drum blade 115 is configured to be expanded and contracted via 119.

  The inner ring 111 is fixed by a pair of left and right inner ring side plates 123 via screws 122, and a lubrication member 121 made of a gun metal having a hole 120 that can be inserted into the outer periphery of the rotation shaft 101 at the center thereof. The spur gear 113 is fitted on the outer peripheral surface of the motor. The inner ring 111 is sandwiched from both sides by a friction plate 104 constituting a friction clutch mechanism, and rotates together with the friction plate 104.

  As shown by a gap d in FIG. 3B, the outer ring 112 has an outer shape formed by a pair of left and right outer ring side plates 124 provided separately from the inner ring 111 on the outer peripheral side of the inner ring 111. Are provided with an eccentric cam 119 with gears and a drum blade 115. As shown in FIG. 2A, in this embodiment, twelve eccentric cams 119 with gears and four drum blades 115 are arranged, and one drum blade is formed by three eccentric cams 119 with gears. 115 is expanded or reduced. The pair of left and right outer ring side plates 124 are connected by a plurality of screws 124s.

  The guide member 114 that regulates the rotational phase angle of the spur gear 113 includes a long hole 114r that is cut out in an arc shape at equal intervals (8 equal intervals in the present embodiment) on the circumference of the spur gear 113, and a pair of outer rings. The guide pin 114p is suspended between the side plates 124, and the rotational phase angle of the spur gear 113 is set within a predetermined range according to the distance that the guide pin 114p moves between both ends inside the elongated hole 114r. Yes.

  As shown in FIG. 2A, the geared eccentric cam 119 is formed with teeth 119g meshing with the spur gear 113 on one end side and sliding on the inner peripheral surface of the drum blade 115 on the other end side. An eccentric cam 119c for gradually expanding and contracting the wing 115 is formed, and is rotatable around a fixed pin 118 suspended between the outer ring side plates 124. By appropriately setting the outer shape and stroke of the eccentric cam 119c, the expansion / contraction operation and distance of the drum blade 115 can be changed arbitrarily.

  The outer peripheral surface of the fan-shaped drum blade 115 is formed in an arc shape having substantially the same diameter as the outer diameter of the outer ring side plate 124, and the inner peripheral surface on which the geared eccentric cam 119 slides is also the same as the outer peripheral surface. It is formed with curvature. An elongated hole 115r is formed at a position where the screw 124s of the drum blade 115 is inserted, so that the drum blade 115 does not interfere with the screw 124s even if the drum blade 115 expands or contracts.

  A tension spring 116 having an end portion fixed to each drum blade 115 via a fixing screw 116 s is suspended between one drum blade 115 and another adjacent drum blade 115. Each drum blade 115 is expanded against the urging force of the tension spring 116 and is contracted by the urging force. 2A and 3A, the inner ring 111 is imparted with counterclockwise rotation indicated by an arrow “expansion”, the drum blades 115 project in the radial direction, and a gap c is formed between the drum blades 115. It shows the state of being formed and expanded.

  As shown in FIGS. 2A and 2C, the guide member 117 that regulates the movement of the drum blade 115 in the radial direction from the axis O of the drum blade 115 and the distance between the center position of the drum blade 115 and the shaft center O. A guide pin 117p that is inserted into and fixed to the drum blade 115 on two straight lines L1 and L1 parallel to the straight line L0, that is, parallel to the straight line L0, and a width in which the guide pin 117p is movable. And a long hole 117h formed in the pair of outer ring side plates 124 with a length. The distance at which the drum blade 115 expands or contracts is set within a predetermined range according to the distance that the guide pin 117p moves between both ends of the long hole 117h.

  Since the winding plate 110 is configured as described above, when the rotation of the rotating shaft 101 gives the inner ring 111 a counterclockwise rotation as indicated by an arrow “expansion”, the spur gear 113 rotates in the same direction. Then, the eccentric cam 119 meshing with the spur gear 113 rotates in the clockwise direction, and the drum blade 115 is expanded, whereby the core C attached to the outside of the drum blade 115 is fixed and held from the inner peripheral surface side, In this state, the belt-like sheet S is wound up.

  When releasing the fixing and holding of the core C, the reverse operation is performed. That is, when the outer ring 112 side is fixed and the inner ring 111 side is rotated in the opposite direction, that is, clockwise, as shown in FIG. 4, the spur gear 113 rotates in the same direction, and the eccentric cam 119 engaged with the spur gear 113 is counteracted. The drum blade 115 rotates in the clockwise direction and is contracted by the action of the tension spring 116, whereby the fixing / holding of the core C is released. FIGS. 5A and 5B show the state of the winding plate 110 at this time corresponding to FIGS. 3A and 3B.

  Therefore, after winding the belt-like sheet S around the core C, the friction winding shaft 100 is removed from the winding device, and the roll Sr of the belt-like sheet S is formed on the product carriage 130 as shown in FIG. When the friction winding shaft 100 is rotated in the anti-winding direction after being placed and fixed in the letter-shaped groove 130m, the winding core 110 is fixed and held by the winding plate 110 and wound around the winding core C. Only the friction take-up shaft 100 can be pulled out with the roll Sr of the belt-like sheet S placed on the product carriage 130.

  As described above, according to the winding plate 110, it is possible to efficiently perform the winding preparation work and the post-processing work of the belt-like sheet S.

  As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this embodiment as above-mentioned.

  For example, the number of guide members 117 that regulate the direction and amount of movement of the drum blade 115, the guide member 114 that regulates the rotation angle of the spur gear 113, the drum blade 115, the eccentric cam 119 with gear, etc. It can be further increased or decreased.

  In addition, although the said embodiment is a case where the strip | belt-shaped sheet | seat S is wound around the winding core C, the winding board which concerns on this invention is in the state similar to a general winding core by making a drum feather into a contracted state. Therefore, the belt-like sheet S can be wound directly on the outer periphery of the winding plate without using the conventional winding core C.
