Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a long body winding device for arranging long bodies such as rubber hoses and electric wire cables in multiple rows on a winding drum and winding them in multiple stages. Regarding.

[Conventional technology]

Conventionally, long objects such as vulcanized rubber hoses are wound onto a winding drum for shipment as final products, and long objects such as unvulcanized rubber hoses are wound onto a winding drum in order to be transferred to the next process. It is being taken.

In this case, in order to arrange the long bodies in multiple rows and wind them in multiple stages, a traverser is used to continuously rotate the winding drum, which has flanges at both ends in the axial direction, with the axis horizontal. A long body winding device is required that reciprocates the long body supplied to the winding drum in the axial direction of the winding drum, or places the winding drum on a cart and similarly moves the long body back and forth.

In such conventional long object winding devices, the winding drum is always rotated at a constant rotational speed by a rotary drive up-and-down.

Further, the traverser or the carriage of the winding drum is connected to the motor for rotationally driving the winding drum via a clutch, a gear, etc.
The elongate body or the winding drum is relatively moved back and forth at a constant speed related to the rotational speed of the winding drum.

However, as the number of winding stages increases each time the elongated object is wound around the body of the take-up drum in an aligned manner from flange to flange, the outer peripheral surface of the elongated object wound on the take-up drum increases. Since the outer diameter increases by twice the diameter of the elongated body, the winding speed on each outer circumferential surface becomes gradually faster. A strong tension will be applied.

In order to prevent this, the feeding speed of the long body should be increased each time the number of winding stages increases, but on the feeding side of the long body, for example, extrusion molding of an unvulcanized rubber hose or braiding of a reinforcing layer, etc.
Generally, it is difficult to change the feeding speed of a long object because it is often subjected to some kind of processing or other operation.For this reason, long objects with plasticity, such as unvulcanized rubber hoses, stretch during winding, causing the outer diameter to decrease. The disadvantage was that it changed.

Furthermore, even if the feeding speed of the long body is set constant on the supply side, the actual feeding speed will usually vary somewhat due to some reasons, especially if the long body supply side is a rubber extruder, etc. In some cases, the supply rate tends to fluctuate. However, in the conventional winding device, the number of rotations of the winding drum and the relative moving speed of the elongated body and the winding drum were constant as described above, so fluctuations in the feeding speed of the elongated body This also resulted in changes in the tension applied to the elongated body, and furthermore, fluctuations in the feeding speed caused disturbances in the aligned winding of the elongated body.

Furthermore, as mentioned above, the traverser or winding drum truck is
The mechanism is complicated because it is connected to the motor for rotating the winding drum through a clutch, gears, etc., and the gears etc. must be replaced every time the outer diameter of the long object to be wound changes. There was a drawback that aligned winding could not be performed without resetting the relative moving speed of the body and the winding drum.

[Problem to be solved by the invention]

In view of such conventional circumstances, the present invention has been provided with the following: Even if the feeding speed of the elongated object fluctuates while the elongated object is being wound around the winding drum, or the number of winding stages of the elongated object gradually increases, the load on the elongated object remains the same. It is an object of the present invention to provide a long body winding device capable of always maintaining a constant tension and winding up a long body in multiple stages without disturbing the alignment of the long body.

In order to achieve the above object, the present invention provides a long body winding device that arranges long bodies in a plurality of rows on the body of a winding drum and winds them in a plurality of stages.

Outer diameter D1 Outer diameter d1 of the elongated object set; Feed speed V of the elongated object detected by the feed speed detection section; starts from zero; adds 1 each time it is detected by the first and second winding end detection sections; Based on the number n formed by the formula % formula %
(1) Equipped with an automatic control device that simultaneously controls the rotary drive motor and the variable movement motor in accordance with the rotational speed N of the winding drum and the moving speed T of the reciprocating elongated body or the winding drum determined by Features.

Furthermore, the elongate body winding device includes a tension detection unit that detects the tension of the elongate body to be supplied, and the automatic control device further controls the rotational drive motor according to the detected tension of the elongate body. It is also possible to further adjust the rotation speed N of the winding drum so that the tension of the elongated body approaches the standard setting value.

〔Example〕

A specific example of the elongate body winding device according to the present invention will be explained with reference to the drawings.

A rotary drive motor 4 having a variable rotational speed, such as a DC motor or an inverter motor, is connected to the shaft of the winding drum 2, and is connected to an automatic control device 6 including a setting section 7 via an accelerator/decelerator 5. Note that even if the rotational drive motor 4 is not connected to the shaft of the winding drum 2 and the rotation of the rotational drive motor 4 is transmitted to the flange 2a or 2b of the winding drum 2, the winding drum 2 cannot be rotated. I can do it.

A rotary encoder 8 is provided on the elongate body supply side of the winding drum 2 and detects the supply speed of the elongate body 1 by bringing a rotary plate 8a into contact with the surface of the elongate body 1. It is connected to the automatic control device 6. In addition, as a means for detecting the feeding speed of the elongated body 1, a speed detector may be connected to a drive unit of a not-illustrated elongated body feeding device to detect the feeding speed.

Further, on the elongate body supply side near the winding drum 2, there is a traverser 10 that reciprocates the elongate body 1 in the axial direction of the winding drum 2.
is the provision. The movable guide section 11 of the traverser 10 is screwed onto a screw shaft 12 connected to a variable motor 13 for movement whose rotation speed and direction are variable.
The winding drum 2 is rotated along the guide bar 14 by forward and reverse rotation.
It is designed to move back and forth in the axial direction. The variable motor 13 for movement is connected to an automatic control device 6 via an accelerator/decelerator 5. Further, near the flange 2as2b of the winding drum 2, there is a winding side end detection part 15a such as a limit switch or a proximity switch connected to the automatic control device 6 via the converter 9.
15b is provided, and each time the movable guide part 11 of the traverser 10 that reciprocates comes into contact with or approaches, a signal is transmitted to the automatic control device 6, and the rotation direction of the variable motor 13 for movement is reversed and the rotation direction starts from 0. A number n (corresponding to the number of winding stages of the long body 1 that has been wound) is obtained by adding 1 each time the rotation direction is switched. Note that instead of the traverser 10, a cart 3 carrying the winding drum 2 may be moved back and forth in the axial direction of the winding drum 2.

A roller 17 pushed downward by a spring 16 is provided on the elongate body supply side of the traverser 10, and the elongate body 1 passing over two rollers 18 provided on both sides of the roller 17 is moved from above. It is designed to be pushed down with a constant load. roller 1
7 is connected to a displacement meter 19, which can detect the amount of displacement of the roller 17 that moves up and down according to the tension of the elongated body 1, and the displacement meter 19 is connected to the automatic control device 6 via a converter 9. . Note that the tension in the elongated body 1 can also be detected by other methods, such as optically measuring the amount of vertical displacement of the elongated body between the two rollers 18.

The automatic control device 6 performs the following control operations: ■ feeding speed V of the elongated body 1 detected by the rotary encoder 8;
Based on the number n1 determined for each detection by the winding end detection parts 15a and 15b, the preset outer diameter D1 of the body of the winding drum 2, and the preset outer diameter d of the elongated body 1, the formula The rotational drive motor 4 is controlled according to the rotational speed N of the winding drum 2 determined by the % formula % (1).

Note that the standard value of the tension of the outer diameter D1 of the body of the winding drum and the outer diameter d1 of the elongated body necessary for the above control is determined by the setting section 7 of the automatic control device 6.
It is input in advance by a digital switch provided in the .

[Effect]

When winding up the elongated body 1 such as an unvulcanized rubber hose onto the winding drum 2, the winding drum 2 having the outside diameter of the body has already been lined in multiple rows.
The outer diameter of the outer circumferential surface of the elongated body having outer diameter d that has been wound in stages is D+2na. Therefore, if the supply speed V of the elongated body 1 on the outer circumferential surface is equal to the rotational speed N of the winding drum 2, the relationship of the above formula (1) N-v/π(D+2na) holds true.

Therefore, by using this equation (1) and changing the rotation speed N of the winding drum 2 according to the control operation (2), the outer diameter D
Since the winding speed of the elongated body 1 to be aligned and wound as the next stage on the outer circumferential surface of Even if the number of stages increases gradually, the tension applied to the elongated body 1 can be maintained constant. Furthermore, even if the outer diameter of the body changes due to replacement of the winding drum 2, or the outer diameter d changes due to a change in the long body 1 to be wound, all that is required is to change the settings to the automatic control device 6. It can be easily dealt with.

In order to wind the elongated body 1 in a plurality of rows, the elongated body 1 and the winding drum 2 are rotated relative to each other by the outer diameter d of the elongated body 1 in the axial direction during one rotation of the winding drum 2. All you have to do is move to .

Therefore, the moving speed T of the winding drum 2 of the traverser 10 or the cart 3 in the axial direction for winding the elongated body 1 in each stage in an aligned manner is TN(L) as shown in equation (2).

Here, since the rotational speed N of the winding drum 2 is simultaneously controlled by the control operation (2) according to equation (1), the outer diameter of the body of the winding drum 2 and the outer diameter d of the elongated body 1 change. Of course, even if the supply speed of the elongated body 1 changes from moment to moment, the elongated body 1 can be aligned and wound up by performing the control operation (2).

Furthermore, the tension of the elongated body 1 may change due to some factors due to control operations (1) and (2), and the tension of the two rollers 18
Displacement such as downward deflection of the elongated body 1 occurs between the two, but in such a case, the rotational speed N of the winding drum 2 is further adjusted by control operation ■ to keep the tension of the elongated body l constant. do.

〔Effect of the invention〕

According to the present invention, since the rotational speed of the winding drum is automatically changed in accordance with the variation in the supply speed of the elongated body and the number of winding stages of the elongated body, Regardless of the number of winding stages of the body, the long body can be arranged in multiple rows and wound in multiple stages, and the tension applied to the long body can always be kept constant, so it is possible to However, it can be wound up without changing the shape such as the outer diameter.

In addition, if the traverser or the carriage of the winding drum is made independent of the motor for rotational driving of the winding drum, and is moved relative to the rotational speed of the winding drum, it is possible to move clutches, gears, etc. as in the past. To enable aligned winding with a simple mechanism that does not require any, and to easily cope with changes in the outer diameter of a long object to be wound, the outer diameter of a body of a winding drum, etc., without replacing gears, etc.
