Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is a precision twill winding device which is capable of obtaining winding bodies with winding pitches corresponding to the fineness of various winding threads.
More specifically, the present invention relates to a precision traverse winding device capable of changing over a wide variety of products, which allows the rotation ratio of a traverse cam and a spindle provided in a winding unit of multiple spindles to be changed simultaneously from separate positions.

[Prior Art] A precision traverse winding device used for winding a filamentous body such as yarn or tape generally has a traverse cam that causes a traverse guide to make reciprocating motion, and a spindle that holds a bobbin and drives it to rotate. The winding pitch of the formed yarn body is set to a desired value by interlocking at a constant ratio through a combination of a timing belt and a timing pulley, or through a positive interlocking means using gears or the like.

[0003] In addition, the above-mentioned conventional precision traverse winding device has a structure in which winding units with multiple spindles are closely arranged in parallel or in a multi-stage, multi-row arrangement in order to improve production efficiency in a limited installation space. It is customary to use it as

However, as described above, in a precision traverse winding device consisting of a collection machine stand of a large number of winding units equipped with a conventional positive interlocking means, in order to switch to winding yarns of different fineness, When changing the winding pitch or the number of winds of the winding body, it is necessary to replace the timing pulley or gear of each winding unit with one with a different number of teeth each time, and change the speed ratio of each winding unit. The work becomes extremely complicated, and when changing the gear ratios of all the cones at once, there is a problem that the down time of the equipment becomes long, resulting in a substantial drop in production efficiency.

[0005] In addition to precision traverse winding devices equipped with mechanical interlocking means such as timing belts, in recent years the traverse cam and spindle have been driven by separate motors, and the rotational speed of each motor has been controlled by an inverter or the like. A system that uses feedback control to maintain a constant wind ratio (ratio of traverse speed to spindle rotation speed) has been proposed and put into practical use; Unlike the above-mentioned mechanical interlocking means, the winding device can easily change the wind speed, but on the other hand, it requires highly sophisticated control of the rotational speed using a computer, so the equipment cost is extremely high.

[0006]

[Means for Solving the Problems] The present invention has been made by focusing on the above-mentioned problems in the work of changing the winding pitch of the conventional precision twill winding device. A precision cheese winding device in which a plurality of spindles of a winding unit are arranged in parallel or in multiple stages and rows for interlocking a traverse cam shaft and a spindle through a variable speed interlocking means that can change the speed ratio in multiple stages by fitting and disengaging, A switching operation panel for the clutch is provided at a position adjacent to a group of winding units with multiple spindles, and by switching the clutches using the operation panel, the speed ratio of the variable speed interlocking means of each winding unit is changed simultaneously, and the speed ratio of the variable speed interlocking means of each winding unit is changed at the same time. It is characterized by obtaining a wound body with a winding pitch corresponding to the fineness.

[0007]

[Operation] The precision traverse winding device of the present invention switches each clutch provided in a plurality of winding units at once by an operator performing a switching operation on the operation panel, and changes the gear ratio of the interlocking means of each winding unit. By switching, a winding body with the desired winding pitch according to each fineness can be obtained, and during the switching operation, the operator can simultaneously adjust the gear ratio of each unit using a control panel located at a distance from the winding unit group. This allows work to be carried out safely and quickly, reduces the time and effort required for gear shift adjustment, and significantly improves production efficiency compared to adjusting each unit individually.

[0008]

[Embodiment] In the precision twill winding device of the present invention, as shown in FIG. An operation panel B for switching the speed ratio of each winding unit A at the same time is installed at an adjacent position separated from the unit A group.

Each of the winding units A is constructed as shown in FIGS. 1 to 4, for example.

In each figure, 1 is a traverse cam shaft, 2 is a traverse cam, 3 is a spindle, 4 is a bobbin holder, 5 is a motor, 6 and 7 are clutches, and P is a package on the bobbin holder. Two large and small timing pulleys 8 and 9 are fixed to the rear end of the traverse cam shaft 1, the spindle 3 is supported on the frame by bearings 10 and 11, and two timing pulleys 12 having the same number of teeth are attached to the rear end of the spindle 3. 13 is fixed.

The clutches 6 and 7 are known electromagnetic clutches in which the input and output shafts are connected to each other when the solenoid inside the casing is energized, and the input and output shafts are free to rotate relative to each other when the solenoid is not energized. The input and output shafts 6 and 7 have timing pulleys 14 and 15 with different numbers of teeth, respectively.
16 and 17 are fixed.

A motor pulley 18 attached to the output shaft of the motor 5, a pulley 9 attached to the shaft end of the traverse cam shaft 1, and a pulley 1 attached to the input shaft of the one clutch 6.
4, a timing belt 20 is wound through a tension pulley 19, and a tension pulley is provided between a timing pulley 15 provided on the output shaft of the clutch 6 and a timing pulley 13 fixed to the shaft end of the spindle 3. 2
A timing belt 22 was wound around the timing belt 22 via 1.

Further, a timing belt 24 is wound through a tension pulley 23 between the inner timing pulley 8 of the traverse cam shaft 1 and a timing pulley 16 provided on the input shaft of the clutch 7. A timing belt 26 was wound through a tension pulley 25 between a timing pulley 17 attached to the output shaft and a timing pulley 12 fixed to the spindle 3. Therefore, between the traverse camshaft 1 and the spindle 3, belt interlocking mechanisms having different transmission ratios (pulley ratios) are interposed, and each system is provided with an electromagnetic clutch 6, 7, respectively.

The electromagnetic clutches 6 and 7 provided in each winding unit A are each connected in parallel to the power source E via a changeover switch 27 provided on the operation panel B, as shown in FIG. When the changeover switch 27 is turned to the contact a side, the electromagnetic clutches b of each winding unit A are energized at the same time, and when the changeover switch 27 is turned to the contact b side, the electromagnetic clutches 7 are energized at the same time. I made it.

In the precision cheese winding device of the present invention constructed as described above, the camshaft 1 is driven at a constant rotation ratio from the pulley 18 through the belt 20 and the pulley 9 by the rotation of the motor 5. A known thread guide (not shown) engaged with a spiral groove is reciprocated in the axial direction of the cam 2, and the input shaft of the clutch 6 is connected to the pulley 14 through the pulley 14, and the input shaft of the clutch 7 is connected to the pulleys 8 and 16. and belt 24
Driven through. At this time, the electromagnetic clutches 6 and 7 are alternately engaged and disengaged by switching the switch 27 on the operation panel B. While the clutch 6 is engaged and operated, the rotational force of the motor 5 is applied to the output shaft. The signal is transmitted from the pulley 15 to the spindle 3 via the belt 22 and the pulley 13. On the other hand, while the clutch 7 is engaged, the pulley 17
is transmitted to the spindle 3 via the belt 26 and pulley 12.

[0016] Thus, when changing the winding pitch of the thread body in each winding unit A at the same time according to the fineness of the yarn, that is, when changing the rotation ratio of the traverse cam 2 and the bobbin holder 4 for each spindle at the same time, By simply switching the engagement and disengagement states of the electromagnetic clutches 6 and 7 alternately, one of the two systems of belt interlocking mechanisms becomes active and the other becomes inactive, making it easy to switch.

In the above embodiment, the traverse cam 2
Although a case has been described in which two systems of belt interlocking mechanisms are interposed between the belt interlocking mechanism and the bobbin holder 4, each system is provided with an electromagnetic clutch, and the systems are alternately switched, the present invention is not particularly limited to this. Instead, the number of belt interlocking mechanisms and electromagnetic clutches in each winding unit may be appropriately increased to increase the number of variable speed ratio stages, or, for example, as shown in FIG. Install T1, T2, T3, T4, T5, T6, T7, T8, and connect between intermediate shaft 31 and gear T3 and output shaft 32.
Electromagnetic clutches 33 and 34 are interposed between the intermediate shaft 31 and the gear T7, and one-way clutches 35 and 36 are interposed between the intermediate shaft 31 and the gear T4 and between the output shaft 32 and the gear T8. It is possible to make improvements such as changing the speed ratio in multiple stages using a speed change mechanism that obtains four speed change ratios by selectively engaging and disengaging the two electromagnetic clutches 33 and 34.

Regarding the above-mentioned switching operation of the clutches 6 and 7, in the above embodiment, it was explained that it is performed only when changing the yarn type, but for example, when starting winding on an empty bobbin, the switching operation is set to a small winding pitch. The clutch of the variable speed interlocking means is actuated to start winding, to reduce sideways slipping of the thread on the surface of the empty bobbin, to prevent thinning of the lower layer of the thread body, and to ensure that the thread layer on the bobbin reaches a predetermined thickness. At this point, the clutch 4 is switched to activate the clutch of the variable speed interlocking means which has been set to a large winding pitch, so that the bulge phenomenon due to tight winding of the thread can be prevented.

Furthermore, the traverse cam shaft 1 and the spindle 3
When a clutch is provided for each of the multiple interlocking mechanisms provided between the It becomes possible to use.

[0020]

[Effects of the Invention] As described above, the precision traverse winding device according to the present invention has an operation panel arranged adjacent to a plurality of winding units,
Using the operation panel, the clutches provided in the variable speed interlocking means of each winding unit are switched all at once to change the gear ratio between the traverse cam shaft and the spindle at the same time, and the winding pitch is adjusted according to the fineness of each type of winding yarn. As a result, compared to a winding device having a conventional mechanical interlocking means, the work of changing the gear ratio is greatly simplified, the work time is shortened, and production efficiency is significantly improved. Compared to a winding device that uses a computer-based wind ratio setting method, the device can be configured at a lower cost, and together with the improvement in production efficiency, a significant reduction in production costs can be achieved. There is.
