Abstract

PURPOSE:To automate the spiral multi-step winding work of a cord-shaped body for labor saving by spirally and regularly winding the cord-shaped body such as a rubber house fed from a traverser at a constant speed so as to allow spiral multi-step winding. CONSTITUTION:The portion of a winding disk 1 arranged rotatably in the horizontal plane corresponding to the tip of a traverser 5 is driven invariably at a constant speed. Moreover, the traverser 5 is shifted in the radial direction of the disk 1 synchronously with the shift of a drive wheel 3 driving the winding disk 1 in the longitudinal direction of a rotary device shaft 2. Therefore, a cord-shaped body such as a rubber hose fed at a constant speed can be automatically wound. In addition, a feed device 4 feeding the cord-shaped body at a constant speed is provided on the traverser 5, and a lifting means 6 lifting the traverser 5 by one step is provided at each end section of the advancing and retreating movement of the traverser 5, thereby the cord-shaped body is spirally wound over the spirally wound one, thus multi-step winding can be automated.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a winding device for a string-like body, and more particularly to a winding device for winding a string-like body continuously fed at a constant speed into a spiral shape. It is.

[Background Art] Generally, a string-like body such as a rubber hose is wound into a spiral shape by moving a traverser on the disk in the radial direction of the disk while driving and rotating the disk. By the way, when a disk is driven to rotate at a constant rotation speed, the speed (angular velocity) at the outer circumference of the disk is faster than the speed at the inner circumference.Therefore, a rubber hose is placed on top of the rotating disk. If such a string-like body is fed at a constant speed, it will not be possible to wind the string-like body in an orderly spiral.

For this reason, conventionally, when winding a string-like body in a spiral shape on a disk, an operator uses his/her foot or the like to control the rotational drive speed of the disk (g!). L
However, the cord-shaped body supplied at a constant speed is manually guided and wound, which causes problems in that work efficiency is poor and it is impossible to wind it in an orderly manner. Moreover, it is even more difficult to perform multi-stage winding, in which the material is rolled up in a spiral shape by stacking it on top of the spirally wound material. This is the current situation.

[Object of the invention 1 The present invention has been made in view of such problems,
The purpose is 1. It is possible to automatically and orderly wind up an a-shaped body such as a rubber hose supplied from a traverser at a constant speed into a spiral shape. It is an object of the present invention to provide a winding device for a string-like body that can automatically perform multi-stage winding in which a string-like body is further layered and wound in a spiral shape.

[Disclosure 1 of the Invention The string-like body winding device of the present invention has a winding disc 1 which is rotatably disposed in a horizontal plane and whose longitudinal direction is directed toward the lower surface side of the winding disc 1 in the radial direction of the winding disc 1. A rotary drive shaft 2 is disposed, and a drive shaft 3, which is provided to be integrally rotatable with the rotary drive shaft 2 and movable in the length direction of the rotary drive shaft 2, is brought into rolling contact with the winding disk 1,
The traverser 5 disposed on the winding disk 1 is reciprocated in the radial direction of the winding disk 1 in synchronization with the reciprocating movement of the rotation drive shaft 2 in the length direction of the drive shaft 3. The traverser 5 is provided with a supply device 4 for supplying the shaped body a at a constant speed, and a lifting means 6 is provided for raising the traverser 5 one by one at each terminal end of the forward and backward movements of the traverser 5. With this configuration, the above object is achieved. In other words, the portion of the winding disk 1 corresponding to the tip of the traverser 5 is always driven at a constant speed. It moves in the radial direction of the winding disk 1 in synchronization with the movement in the length) The cord is wound up in a spiral shape at a constant winding speed, and the cord-like body a, such as a rubber hose, which is supplied at a constant speed, can be automatically wound up, thereby saving labor. In addition, the traverser 5 is provided with a supply device 4 for supplying the string-like body a at a constant speed, and a lifting means 6 is provided for lifting the traverser 5 one by one at each terminal end 1 of the forward and backward movements of the traverser 5. By providing this, the string-like body a is wound in a spiral shape by being superimposed on the spirally wound object.In this way, the spiral winding is performed in a continuous manner in multiple stages, and the multi-stage winding is automated. This is what I did.

Next, a drive system in which the traverser 5 is driven to move in the radial direction of the winding disk 1 to spirally wind the string-like body a such as a rubber hose will be described.

As shown in FIG. 2, the central shaft 9 that drives and rotates the winding disk 1 extends upward through the winding disk 1, and a receiving body 41 is attached to the upper end of this extending portion. The receiving body 41 can be driven and rotated at the same speed as the winding disk 1.

The tip of the traverser 5 is placed above the receiving body 41 so that the string-like body a can be supplied to the upper surface of the receiving body 41 from the traverser 5.

As shown in FIG. 6, for example, eight protrusions T1 to T8 are attached to the lower surface of the winding disk 1 at equal intervals in the circumferential direction. A limit switch S is attached to the fixed piece 42, and eight protrusions T, ~'''.

This allows the limit switches S to be operated one after another. The number of actuations of the limit switches S operated in this way is counted by the counter of the control panel 43, and when the cumulative sum reaches seven (the number of protrusions T - 1), an intermittent operation is performed by a signal from the controller of the control panel 43. Transportation means 7
By driving the traverser motor 44 as 5, the traverser 5 can be moved intermittently by one pitch (an amount equal to the thickness of the string-like body a).

Therefore, by intermittent operation of the traverser motor 44, the traverser second transmission shaft 47 is intermittently rotated at a constant rate, and the construction body 53 is
This allows the traverser 5 to be moved intermittently by a certain amount (an amount approximately corresponding to the thickness of the string-like body a).

A traverser stand 19 on which a traverser 5 is mounted which is driven and moved intermittently in the radial direction of the winding disk 1 in this manner.
The end of the reciprocating movement can be detected by the limit switch SII S2. Traverser stand 1
9 is equipped with a motor 21 as a lifting means 6,
The motor 21 is operated based on the detection of the end of the reciprocating movement of the traverser table 19 by the limit switches S , , S 2 , and the traverser 5 is moved by a fixed amount approximately equivalent to the thickness of the string-like body a through the ball rope pongee 56. This allows the winding body to be lifted up and further spirally wound on top of the spirally wound winding body.

As shown in FIG. 8, an inner guide 57 and an outer guide 58 are arranged at intervals in the circumferential direction above the receiving body 41, and a string-like body a is spirally arranged between the inner and outer guides 57 and 58. This allows winding to be guided in multiple stages. The configuration will be explained below.

As shown in FIG. 8, the vertical frame 5 erected on the base frame 17
The frame 60 is held movably up and down at 9, and the up/down frame 60 can be driven up and down by an up/down shilling 69.

Seven radial frames 61 are attached to the elevating frame 60, and an outer guide 58 is attached to the tip of the seven radial frames 61.
... are suspended on approximately the same circumference, and the radial frame 61
An inner guide 57 is suspended from the inner end of the inner guide 57 on substantially the same circumference. As shown in FIG. 5, the outer guide 58 is pivotally attached to the tip i portion of the radial frame 61 by means of a pin 62 so as to be rotatable in the inner and outer directions.

The upper end of the outer guide 58 extends above the seven radial frames 61, and this extension is connected to a movable link 63 provided above the seven radial frames 61 so as to be movable in the length direction of the seven radial frames 61. The movable link 63 interlocked with the outer guide 58 is pivotally connected to the bin 64 so as to be freely rotatable, and when the outer guide 58 opens and rotates in the direction of the arrow in FIG. The outer guide 58 is opened and rotated by the amount of movement within the range of , and its guide function can be canceled. The inward rotation of the outer gamma guide 58 is prevented by a stopper 66, so that the outer guide 58 is in a hanging position so that it can be guided in a predetermined manner. The stopper 66 has 7 radial frames 61
The winding diameter can be changed by changing the mounting position. The inner guide 57 is also radial 7
By changing the position with respect to the frame 61, it is possible to cope with changes in the winding diameter. As shown in FIG. 3, a hexagonal cam 67 is rotatably provided on the inner end side of, for example, six movable links 63 arranged radially. The cam 67 is configured to be driven and rotated by a rotary ring 68. By rotating the cam 67 by the rotation sill 68, the movable link 63 is moved within the range of its elongated hole 65, and the outer guide 58 is rotated from the guide position to the non-guide position. It is possible to do so.

As shown in FIG. 8, a receiving body 41 driven at the same speed as the winding disk 1 is formed in a radial shape, and a multi-stage winding body C wound spirally in multiple stages is placed on this receiving body 41. This allows it to be easily tied together.

In addition, the gear group 52 and the continuously variable transmission mechanism 27 can be changed depending on the diameter of the string-like body a and the operation of the handle pongee 70 i
1! This allows you to adjust the settings. Further, the winding disk 1 is raised by the operation of a lifting ring 71 provided below the winding disk 1 through a link 72 at the central shaft 9 which is a ball spline shaft. , the winding disc 1 can be lifted from the drive wheel 3 to cut off the drive of the winding disc 1.

With the above configuration, the operation of spirally winding the string-like body a and the multi-stage winding operation of winding the cord-like body a in multiple stages will be described.

As shown in FIG. 4, the drive wheel 3 and the traverser 5 are
1, drive the C motor 13, and the driving force of the VC motor 13 causes the first chain 16,
The drive wheel 3 is driven and rotated via the rotary drive shaft 2, and the winding disk 1 that is in contact with the drive wheel 3 is driven and rotated.
This rotation of the winding disk 1 drives and rotates the receiving body 41 via the central shaft 9 at the same speed as the winding disk 1. On the other hand, the VC motor 13 operates the second chain 25, the continuously variable transmission mechanism 27, the third chain 28, and the traverser input shaft 15.
, vertical pongee 29r? The clamping guide loaf 40 is driven through the intermediate conduction section of the clamping guide loaf 40 to supply the string-like body a between the clamping guide rows 240 above the receiving body 41.

In such a case, the supply speed of the string-like body a becomes equal to the angular velocity of the portion of the receiving body 41 to which the string-like body a is supplied, and the string-like body a is stably wound on the receiving body 41 in a substantially perfect circle. It will be taken. Then, eight protrusions T1 on the lower surface side of the winding disk 1
When the seven protrusions T1 to T7 of ~T8 kick the limit switch S, the traverser motor 44 is activated by a signal from the control panel 43, and the traverser 5 is moved by an amount approximately equal to the diameter of the string-like body a. is intermittently moved inward of the receiving body 41. As the traverser 5 moves like this, the drive wheel 3
is also moved inward of the winding disk 1 via the construction body 53, and the angular velocity of the portion of the receiving body 41 to which the string-like body a is supplied by the traverser 5 is made to match the supply speed of the string-like body a. .

Thus, the string-like body a is wound in a substantially perfect circle inside the outermost portion of the spiral. Also in this inner portion, when the next seven protrusions T8 to T6 kick the limit switch S, the traverser 5 is moved inward by one pitch and winding is performed in the same manner as described above. In this way, inward winding is performed one after another, and the string-like body a is wound stably in a spiral shape (see figure m7). When such spiral winding is completed, the limit switch S on the inner circumferential side detects the movement position of the traverser 5, and based on this detection result, the lifting motor 21 is intermittently operated, and the ball screw pongee 56 The traverser 5 is raised by an amount equal to the diameter of the string-like body a, and the traverser 5 is wound in a spiral manner as described above from the inner circumferential side onto the winding body which has been spirally wound in the lower stage. Do it. In this way, multi-stage winding is performed. When the multi-stage winding is completed, the C motor 13 is stopped, the rotary ring 68 is activated, and the cam 67 is rotated half a pitch from the state shown in FIG. into a non-guided state that allows rotation. After the multi-stage wound body C is bound on the radial receiver 41, the inner and outer guides 57 and 58 are raised by the elevating sill-69, and the multi-stage wound body C is taken out.
