Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for ropes, strings, etc., which does not have a winding core or a winding shaft and winds up into a block shape.

The winding device of the present invention winds up a block having no winding core or winding shaft.

The winding method for winding up this lump has a spiral shape with gaps, and consists of a combination of a winding means and a guide device that guides the spiral winding, and the related operations of the winding means and the guide device are optional. By selecting the desired length, the interval between the spiral windings can be adjusted, and a string of a desired length can be wound into a desired shape and size.

Next, an embodiment of the present invention will be described with reference to the drawings. A motor 2 is fixed to a base 1, and a winding shaft 5 connected to a winding frame 4 formed by a tapered shaft 3 is mounted on a bearing 6. It is rotatably supported on the shaft, and
A belt 11 is stretched around one of the two pulleys 7 and 8 fixed to the winding shaft 5 and an output pulley 10 attached to the output shaft 9 of the motor 2.

Adjacent to the installation position of the winding frame 4, a string guide mechanism 12 is provided which can be moved by operation in a direction perpendicular to the axis of the tapered shaft 3 in the winding frame 4. This string guide mechanism 12 rotatably supports a guide roller 13 in bearings 14, parallel to the axis of the tapered shaft 3 to which the winding frame 4 is attached. A spiral groove 15 is bored on the outer periphery of the guide roller 13 from one end to the other end.
is formed so that it spirals back to the starting end from the other end and connects, making it endless. In this way, spiral groove 1
A pulley 17 is fixed to an input shaft 16 protruding from one end of a guide roller 13 having a screw threaded thereon. hand over.

The pulley 17 on which this belt 19 is hung can be converted to a pulley of any diameter so that any desired rotation speed can be obtained from a certain rotation speed of the tapered shaft 3, and also, The tension pulley 18 is also configured to arbitrarily adjust the degree of slack of the belt 19 and the load pressure to provide interlocking and somewhat constant sliding rotation with respect to the pulley 17 during rotation transmission. A sliding rail 20 runs parallel to the guide roller 13 between the two bearings 14, 14 which pivotally support the guide roller 13 in this way.
is provided, and the guide piece 21 is slidably engaged with the sliding rail 20. A guide pin 22 provided on the lower surface of this guide piece 21 is inserted into and engaged with the spiral groove 15 of the guide roller 13, and due to the passive action of the guide pin 22 engaged with the rotation of the guide roller 13, the guide piece 21 is moved into a sliding rail. 20 can be moved laterally. The embodiment of this guide piece 21 will be described in detail. The guide piece 21 consists of a sliding part 21' and a guide part 21'', and the guide part 21'' connected to the sliding part 21' inserts the guide roller 13. The tip of the guide pin 22 can be engaged with the inner periphery of the insertion hole having an inner diameter slightly larger than the diameter of the guide roller 13 corresponding to the groove depth of the helical groove 15 of the guide roller 13. In addition, an adjuster 22' is screwed into the guide portion 21'' at a position facing the tip of the guide pin 22, and its tip slides on the outer periphery of the guide roller 13. By appropriately adjusting the distance relationship between the tip position of the adjuster 22' and the tip position of the guide pin 22, the sliding movement of the guide piece 21 corresponding to the guide roller 13 is made smooth. be.
A string guide trough 23 oriented toward the tapered shaft 3 is pivotally attached to the upper part of the guide piece 21 formed in this manner with a pin 24 so as to be rotatable in the vertical direction. Note that the string guide mechanism 12 is formed by interposing a gutter orientation adjustment member 25 containing a spring for regulating the orientation state of the string guide gutter 23 between a part of the guide piece 21 and the string guide gutter 23. be.

30 in the figure is a tension adjustment mechanism for the supply string, and the frame 3 is provided via a connecting rod 31 connected to a part of the base 1.
2 is equipped with a gutter 33 through which a string passes, a gate-shaped adjustment frame 34 is erected from a part of the frame body 32 on the outside of the gutter 33, and a push piece 36 at the lower end of the press rod 35 is supported by the adjustment frame 34. is inserted into the gutter 33 so as to provide resistance to the string A passing through the gutter, and a spring 37 is inserted between the pusher piece 36 and the adjustment frame 34 against the elastic force and is adjusted. An adjustment handle body 38 is screwed onto a male thread of a pressing rod 35 protruding from the upper part of the frame 34.

Further, reference numeral 26 denotes a nut which allows the winding frame 4 engaged with the smaller diameter end of the tapered shaft 3 to be engaged and disengaged during attachment and detachment.

Next, to explain the operation of the present invention, before starting the device, the end of the string A to be wound is guided from the inside of the winding frame 4 fixed to the large diameter end of the tapered shaft 3 to the outside. A knot is formed so that the string A does not come off, and then the middle part of the string A is guided to the string guide gutter 23 of the string guide mechanism 12, and the middle part of the string A is further tensioned to the gutter 33 of the tension adjustment mechanism 30. The pressing piece 36 is engaged with and pressed downward from above with a pressing piece 36 adjusted to a desired pressure. Once the preparation for the string winding operation is completed in this way, the winding operation begins. When the motor 2 is operated, the tapered shaft 3 and the guide roller 13 are rotated via the belts 11 and 19.
As the tapered shaft 3 rotates, the string A is wound around the outer periphery of the tapered shaft 3. At this time, the guide roller 13 also rotates, and the guide pin 22 of the guide piece 21 is engaged with the spiral groove 15 bored on the outer periphery of the guide roller 13, and the guide pin 22 of the guide piece 21 is engaged with the sliding rail 20. Since the guide piece 21 is restricted by the sliding rail 20 and is allowed to move only in the lateral direction, the guide pin 22 is guided by the spiral groove 15 and is integrated with the guide pin 22.
1 moves horizontally. The string A, which is engaged with the string guide trough 23 attached to the guide piece 21, reciprocates over a certain distance in the left-right direction from the string supply position to the outer periphery of the tapered shaft 3 due to the lateral movement of the guide piece 21. The string supply position performs a reciprocating motion in a direction perpendicular to the axial direction of the tapered shaft 3, and the tapered shaft 3 is also rotated due to this feeding movement, so the string A is wound in a spiral around the outer circumference of the tapered shaft 3. It is something.

In the upper action, the distance between the rear end of the string guide trough 23 that moves laterally and the tip of the trough 33 in the tension adjustment mechanism 30 constantly changes, and in order to prevent loosening during winding due to changes in the movement of the string A. The tension adjustment mechanism 30 provides a flow resistance to the flowing string A, and the string A is wound only by the tensioning action caused by the rotation of the tapered shaft 3. Therefore, the string A to be wound is A constant load is always applied, and the hardness of the rolled mass is always constant.

Further, by changing the rotational speed of the tapered shaft 3 and the rotational speed of the guide roller 13, the pitch of the spiral in the winding string can be changed.

These spiral pitch changes can be achieved by converting the pulley 17 fixed to the input shaft 16 of the guide roller 13 to a pulley 17 with a different diameter.Furthermore, in the case of a slight pitch change, This is made possible by changing the degree of tension of the tension pulley 18 and imparting a sliding phenomenon to the rolling contact between the pulley 17 and the belt 19 without changing the pulley. Even if the former pulley is changed to a pulley having a different diameter, it is not necessary to change the belt 19 every time the belt 19 is changed since the tension pulley 18 is interposed therebetween.

In this way, when a desired length of string A is wound up, the operation of the motor 2 is stopped, the knot at the end of the string provided on the outside of the winding frame 4 is untied, and then the small diameter of the tapered shaft 3 is untied. The nut 26 at the end is removed, the winding frame 4 is removed, and the rolled-up string mass is pulled out from the tapered shaft 3.

As described above, the device of this invention winds up the string and
A guide roller 13 adjacent to the tapered shaft 3 for winding into a string block and parallel to the axial direction of the tapered shaft 3
An endless spiral groove 15 is bored in the outer periphery of the guide roller 13, and a guide piece 21 is slidably engaged with a sliding rail 20 provided parallel to the guide roller 13. A guide pin 22 protruding from a part of the guide piece 21 is inserted into and engaged with the spiral groove 15 of the guide roller 13, and a string is pivotally attached to the upper part of the guide piece 21 so that it can freely rotate in the vertical direction. The tip of the guide gutter 23 is installed so as to reach the tapered shaft 3, and the tapered shaft 3 and the guide roller 13 are operated in conjunction with each other.

This invention is particularly concerned with the type, form, thickness,
Even if the string composition conditions are different, such as hardness, etc., the winding form, i.e., the shape density of the rolled lump, the length of the winding length, etc., is determined by the pulley 17 that drives the guide roller 13. By selecting the diameter and giving a difference in the rotation ratio with the tapered shaft 3, the above configuration can be set arbitrarily, and even when replacing the pulley 17 with a different diameter, the belt 19
Since the tension pulley 18 is engaged with the tension pulley 18, it can be operated freely by selecting the degree of tension, and if there is a slight change in the winding form, the tension pulley 18 can be adjusted without changing the pulley 17. This is made possible by creating a sliding phenomenon by changing the degree of close contact between the belt 19 and the pulleys 8, 17 only by changing the degree of tension. In this way, by interlocking the guide roller 13 with the taper shaft 3 for winding the string A of any kind and form, the winding operation of the string A can be started and the string guide mechanism 12
The leading end of the string guide trough 23 that supplies the winding string A to the tapered shaft 3 performs a horizontal reciprocating motion at a speed arbitrarily corresponding to the rotational speed of the tapered shaft 3 at a position parallel to the rotating tapered shaft 3. In combination with the positioning of the string supply position at the tip of the string guide trough 23 and the winding action by the rotation of the tapered shaft 3, the string A to be wound is
The shape is automatically formed into a helical stacked mass.

In this way, the present invention can perform the operation in conjunction with the tapered shaft 3 on the string winding side and the supply positioning device of the string guide gutter 23 on the string supply side, and also perform these operations automatically. It is characterized by obtaining.
