The input shaft 1 is connected to a motor (not shown) through a belt 2 and rotated in a fixed direction, and the rotation of the input shaft 1 is transmitted to the first transmission shaft 5 through gears 3 and 4. An electromagnetic clutch 7 with a gear 6 attached side by side and a first worm gear 8 are fitted on the first transmission shaft 5, and a second worm gear 8 is fitted on the first transmission shaft 5.
An electromagnetic brake 11 in which a gear 10 is attached side by side so as to mesh with the gear 6, and a second worm gear 12 are fitted onto the transmission shaft 9. A differential mechanism 40 is attached to the intermediate shaft 13 rotatably supported below both transmission shafts 5 and 9.
The differential mechanism 4 is engaged with the first worm gear 8.
The first worm wheel 14 connected to the external gear 0 and the second worm wheel 15 meshed with the second worm gear 12 and connected to the internal gear of the differential mechanism 40 are respectively fitted, and the electromagnetic clutch 7 is demagnetized and the electromagnetic brake 11 is energized, the second transmission shaft 9 is stopped and the rotation of the first worm gear 8 is transmitted to the intermediate shaft 13 via the first worm wheel 14, while the electromagnetic clutch 7 is energized. However, when the electromagnetic brake 11 is demagnetized, the second transmission shaft 9 rotates, and the rotation of the second worm gear 12 is transmitted to the intermediate shaft 13 via the second worm wheel 15.
The direction of rotation of the intermediate shaft 13 is switched every time 1 de-energizes, and the intermediate shaft 13 is driven to rotate in forward and reverse directions. and is transmitted to the drive shaft 16.

A lifting drum 23 connected via a belt 22 to a ring rail 21 to which a large number of rings 20 are attached is connected to a drum 24 fitted to a drive shaft 16, and a belt 25 connected to this drum 24 and a belt 25 connected to this drum 24. The ring rails 21 are connected to be rotatable in forward and reverse directions via a drive member 26 fixed to the belt 25, and the ring rail 21 is moved up and down in a reciprocating manner by the forward and reverse rotation of the drive shaft 16.

Detection shaft 27 rotatably supported below the drive shaft 16
The rotation of the drive shaft 16 is transmitted through a belt 30 that is hung between the pulleys 28 and 29, and a reset lever 31 fitted to the detection shaft 27 holds the ring 20 at a certain lower end position. A detection switch 3 is movably installed to define the lowering end position of the ring 20 when a building motion is adopted to change from the ascending stroke to the descending stroke.
When the reset lever 31 rotates together with the detection shaft 27 and approaches the detection switch 32 during the downward stroke of the ring 20, the contact of the detection switch 32 is switched, and the point of contact of the detection switch 32 is switched. At this point, each lift stroke, that is, the ring lifting stroke ends.

A rotary encoder 33 is installed opposite the detection shaft 27 in order to transmit a pulse signal proportional to the ascending distance or the ascending/descending distance of the ring 20, and the input shaft of the encoder 33 is attached to the pulley 29 and the pulley 34. The rotation of the detection shaft 27 is transmitted through the belt 35 , which rotates the rotor of the encoder 33 in forward and reverse directions, and the pulse signal that the encoder 33 emits in synchronization with the movement of the ring 20 is transmitted to the controller 36 . .

The controller 36 has the total lift length l of the package, the length l1 of the upper taper part t1, and the length l1 of the lower taper part t.
2, the pitch P1 of the upper tapered part t1 (difference between the rising end position of the ring in the nth lift stroke and the rising end position of the ring in the n+1th lift stroke), and the pitch P1 of the lower tapered part t2. Pituchi P
2 (difference between the lowering end position of the ring in the nth lift stroke and the lowering end position of the ring in the n+1th lift stroke), etc., is input into the controller 36 by a console 37
and a selection switch 38 for selecting the building motion method for forming the package. The controller 36 also includes a counter for counting the number of pulse signals transmitted by the encoder 33 and a memory (ROM) that stores programs for various building motions. , the upper tapered portion t1 based on the winding shape data inputted in advance to the controller 36;
Alternatively, it is provided with a calculation device that calculates the lift length value in each lift for forming the upper and lower tapered portions t1 and t2. Note that the ROM can be replaced if the program is long.

Next, a building method for forming a tapered top-wound package (see FIG. 3A) in which the lower end position of the ring 20 is constant and has a tapered portion t1 only at the upper portion will be described.

Prior to the start of machine operation, winding shape data such as the total lift length l of the package, the length l1 of the taper part t1, and the pitch P1 of the taper part t1 are input from the console 37 to the controller 36. Select the method using the selection switch 38. Based on the winding shape data input to the controller 36 and the selected building motion program, the controller 3 determines the lift length value in each lift stroke, that is, the ascending distance or ascending/descending distance of the ring 20.
It is calculated by 6.

When the ring 20 starts rising from the lower end position by driving the building mechanism K, the encoder 33
emits a pulse signal proportional to the distance the ring 20 has ascended, and the number of pulses is counted by a counter in the controller 36. When the count value obtained by counting the number of pulses matches the calculated value of the lift length calculated by the controller 36, the controller 36 transmits a switching signal that defines the ascending end position of the ring 20, and the electromagnetic clutch 7 and the electromagnetic brake 11 are activated. In operation, the ring 20 is converted from an upward stroke to a downward stroke. Furthermore, when the ring 20 descends and the detection shaft 27 rotates, causing the reset lever 31 to approach the detection switch 32, the detection switch 32
The contacts are switched and this switching signal is transmitted to the controller 36, and the controller 36 sends a signal to specify the lowering end position of the ring 20, and the electromagnetic clutch 7 and the electromagnetic brake 11 are respectively operated to return to the ring 20. is changed from the downward stroke to the upward stroke, and at the same time when one lift stroke is completed, the count value of the counter is reset to the initial value for restarting counting, that is, 0, by switching the contact of the detection switch 32, Subsequently, the above series of package forming operations are repeated. When forming the taper portion t1, the lift length L of the ring 20 in each lift is a distance corresponding to the sum or difference between the number of pulses proportional to the ascending distance of the ring 20 in the previous lift stroke and the number of pulses proportional to the pitch P1. , and each time the ring 20 rises, the rising end position of the ring 20 is displaced upward or downward by a pitch P1. For example, in the building motion system shown in FIG.
P1,l-l1+3P1,...,l,l-P1,l
-2P1, l-3P1, ..., l-l1, and this cycle is repeated.

The building motion for forming a package cage with a tapered top winding shape is as follows: (1) The polygonal line connecting the rising end positions of the ring 20 is repeated in the shape of a mountain, and the lift length L gradually increases from the minimum lift length to the maximum lift length, and then The building motion repeats a cycle of gradually decreasing from the maximum lift length to the minimum lift length (see Figure 3 B) (2) The polygonal line connecting the rising end positions of the ring 20 is serrated, and the lift length changes from the minimum lift length to the maximum lift. A building motion that repeats a cycle of gradually increasing the length of the ring (see Figure 5 A) (3) The polygonal line connecting the rising end position of the ring 20 is
Building in which the cycle in which the lift length gradually decreases from the maximum lift length to the minimum lift length is repeated in a shape opposite to the polygonal line in (2) (see Fig. 5B) (4) The upper end position of the ring 20 and the lift length L are determined during the building process. There are building motions (see Figure 5 C) in which the straight line connecting the rising ends slopes downward midway through the building process, and the lift length L gradually decreases midway through the building process (see Figure 5 C). A system program is stored in the ROM of the controller 36, and an arbitrary building motion can be selected using the selection switch 38.

Next, a building method will be described in the case where the lower end position of the ring 20 is indefinite and a package in the form of a pirn winding (see FIG. 4B) having an upper tapered portion t1 and a lower tapered portion t2 is formed.

Before operating the machine, the total lift length l of the package, the length l1 of the upper tapered part t1, and the length l1 of the lower tapered part t2 are determined.
The winding shape data such as the length l2, the pitch P1 of the upper tapered part t1, and the pitch P2 of the lower tapered part t2 are input from the console 37 to the controller 36, and the building motion method is selected by the selection switch 38. The lift length value for each lift stroke is calculated by the controller 36 based on the winding shape data input to the controller 36 and the selected building motion method program.

When the machine starts operating and the ring 20 starts moving up and down from the lower end position, the encoder 33 sends a pulse signal proportional to the ascending distance of the ring 20, and the number of pulses is counted by the counter of the controller 36. . When the count value counted during the upward stroke of the ring 20 matches the calculated value of the lift length calculated by the controller 36, the controller 36 sends a switching signal to operate the electromagnetic clutch 7 and the electromagnetic brake 11, respectively.
0 is converted from an upward stroke to a downward stroke. In the descending stroke of the ring 20, the number of pulses transmitted by the encoder 33 is continuously counted in the same way as in the ascending stroke, and when this count value matches the lift length calculation value calculated by the controller 36, the electromagnetic clutch 7 At the same time that the brakes 11 are reset and the ring 20 is changed from the downward stroke to the upward stroke, the count value of the counter is reset to 0, one lift stroke is completed, and the series of package formation described above is continued. The action is repeated. The rising end position of the ring 20 in each ring rising stroke is displaced upward or downward by the pitch P1 of the upper taper portion t1 from the previous rising end position of the ring 20, and the lowering of the ring 20 in each ring descending stroke The end position is the previous ring 20
The lower tapered portion t2 is displaced upward or downward by the pitch P of the lower tapered portion t2 from the lowering end position. In addition,
During the formation of a pie-wound package, the reset lever 3 moves away from the detection switch 32 and the detection switch 32 is not turned on or off.

The building motion for forming a pirn-wound package cage is as follows: (1) A building motion in which the lift length is always constant by repeating a mountain shape in which both fold lines connecting the ascending end position and the descending end position of the ring 20 are parallel. (See Fig. 4B) (2) The two fold lines connecting the ascending end position and the descending end position of the ring 20 are irregularly shaped mountain-shaped folds, and the lift length L gradually increases and decreases alternately, forming the upper and lower tapered parts t1 and t2. Building motions in which the lengths l1 and l2 of the ring 20 are different (see Fig. 6A) (3) The two straight lines connecting the ascending end position and the descending end position of the ring 20 are gradually approaching each other, and the lift length L is A building motion that gradually decreases (see Fig. 6B) (4) A building motion that gradually increases the lift length L, where the straight lines connecting the ascending end position and the descending end position of the ring 20 are gradually spaced apart from each other ( (See Figure 6C) (5) A building motion in which the lift length L alternately gradually decreases and gradually increases, with the two fold lines connecting the ascending end position and the descending end position of the ring 20 repeating in a vertically symmetrical mountain shape. (See Figure D) (6) The two folded lines connecting the rising end position of the ring 20 are repeated in the shape of a mountain, and the straight line connecting the falling end position is tilted upward, and the lift length L alternately gradually decreases and gradually increases, and gradually decreases overall. However, a building motion in which the lengths l1 and l2 of the upper and lower tapered parts t1 and t2 are different (see Fig. 6E) A building motion in which the lift length L is constant in the form of an inclined line (see Fig. 6 F) (8) The two folded lines connecting the ascending end position and the descending end position of the ring 20 are parallel to each other in a sawtooth shape, and the lift length L is constant. There are fixed building motion methods (see Fig. 6G), etc., and the program for each building motion is stored in the ROM of the controller 36, and any desired building motion method can be selected using the selection switch 38. Can be done.

In addition, in the above-mentioned building mechanism K, the worm gears 8, 12, the worm wheels 14, 1

A hydraulic cylinder and a directional switching valve are provided in place of the electric mechanisms such as the electromagnetic clutch 7 and the electromagnetic brake 11, and the piston shaft of this hydraulic cylinder is linked to, for example, the drive shaft 16, and the switching signal of the controller 36 or the detection switch 32 is connected to the piston shaft of the hydraulic cylinder. The ring 20 may be moved up and down by operating the direction switching valve by turning it on and off, and controlling the forward and backward movement of the piston shaft.

Next, the operation and effects of the embodiment having the above configuration will be explained.
