Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bobbin switching device in a continuous winding device for a wire rod such as a cord that serves as the core of a belt.

(Prior art) For example, for a cord (wire rod) as a core of a belt,
In order to improve adhesiveness, a dip treatment device is known that performs a dip treatment to adhere an adhesive to the surface of the substrate.

In such a dip processing apparatus, in order to increase the winding efficiency, it is conceivable to perform dip processing on the untreated coat or the two rolled cheeses in succession.

However, in such a case, there is a request to wind a dip-treated cord onto a winding bobbin for each thread wound with yarn, and if this is done, there will be zero parts of the belt. Whether the cord will be wound continuously on the first and second winding bobbins coaxially arranged in parallel with a predetermined interval, or which bobbin to start from when winding starts. For example, do you need to specify it with a select switch? Therefore, if a bobbin is designated with the select switch at the start, the winding will be alternately performed thereafter by the control section.

(Invention or problem to be solved) However, for example, the winding operation ends on the day when it is started from the first winding bobbin as specified by the select switch, or during the winding on the second winding bobbin. Then, when the power is turned OFF, the control section is normally cleared, and as a result, the information that was being wound on the other winding bobbin is also cleared, so the next day, the second winding bobbin is selected using the first select switch. If you forget to do this, the select switch will remain in the state where the first winding bobbin of the previous day was selected, and there is a risk that a winding error will occur.

The present invention has been made in view of the above, and provides a bobbin switching device for a continuous wire winding device that can automatically switch the winding bobbin and prevent the occurrence of double winding mistakes. The purpose is to

The automatic winding machine 6, as shown in FIGS. 4 and 5,
Before the dip-treated cord 5 is wound on the hobbins 7A and 7B, a traverse pulley 81 on which the cord is wound is rotatably supported on a movable base 82, and
, 7B, and is movably screwed into a threaded rod 83 extending along the axis of the two.

The threaded rod 83 is rotationally driven by a stepping motor 84, and by rotating the threaded rod 83, the movable base 82 and therefore the traverse pulley 81 are moved between the first winding bobbin 7A and the second winding bobbin 7B. The winding of the cord 5 can be changed from the first winding bobbin 7A to the second winding bobbin 7B or vice versa. Further, the movable base 82 has an engagement protrusion 86 that protrudes rearward and slidably engages with a fixed rail member 85 extending parallel to the threaded rod 83.
The movable base 82 is prevented from rotating due to the rotation of the movable base 82.

Further, a limit switch 87 is disposed between the first and second take-up bobbins 7A and 7B, and when the traverse pulley 81 is moved from the first take-up bobbin 7A to the second take-up bobbin 7B, or When moving in the opposite direction, the contact 87a of the limit switch 87 is changed to inform the operator on which winding bobbin 7A, 7B the cord 5 is currently being wound. ing. That is, for example, when the cord 5 is wound on the second take-up bobbin 7B, it is in the state shown in FIG. 6, or it is in the state shown in FIG. When the traverse pulley 82 moves, the engaging portion 82a protruding downward from the traverse pulley 82 comes into contact with the contact 87a of the limit switch 87, and the contact 87a is reversed as shown in FIG. The situation will be as shown below. By this, it is possible to determine which winding bobbin 7A or 7B is currently being wound by looking at the contact 87a, and by linking this limit switch 87 with a separately provided display means, it is possible to determine which winding bobbin 7A or 7B is currently being wound. It may also be possible to display whether winding is in progress on the winding bobbins 7A, 7B.

The first and second take-up bobbins 7A and 7B have a flange portion 7a,
7a, 7b, 7b, and are fixedly attached to flanges 91a, 91b formed on bobbin shafts 91A, 91B with screws 92, 92.

The bobbin shafts 91A, 91B are connected to the casings 93A, 9
The end portion is inserted into 3B and rotatably supported,
A synchronized pulley on the driven side (40 teeth, only the link pulley 94 inside the casing 93A is shown) is fixedly attached to the end. This synchronized pulley 94 on the driven side is linked to a synchronized pulley 96 on the driving side via a synchronized belt 95. The bobbin shaft 96a of the synchronized pulley 96 on the driving side is inserted into its end or into another casing 9 located between the casings 93A93B, and the bearing 98
It is rotatably supported via a, and its end can be connected to the clutch shaft 100 via the first clutch means 99A. The clutch shaft 100 is rotatably supported near the center of the casing 97 by two bearings 101a and 1.01b, and is supported by a synchronized pulley 102 (60 teeth) linked to a drive means (not shown). The installation is fixed. Note that either the first proximity switch 103 that detects one rotation of the clutch shaft 100 or the clutch shaft 100
It is located near the.

Similarly, a bobbin shaft 104 can be connected to the opposite side of the clutch shaft 100 via another second clutch means 99B, and the driving force is transmitted to the second winding bobbin 7B by a similar mechanism. is configured to do so.

Further, near the threaded rod 83, second to fifth proximity switches 105A, 105B, 1 are provided corresponding to both ends of each bobbin 7A, 7B (near the flange portions 7a, 7a, 7b, 7b).
05C and 105D are provided to detect the position of the traverse pulley 81 and change the moving direction of the traverse pulley 81 (the feeding direction of the cord 5). That is, the second to fifth proximity switches 105A, 105B
.

When the controller 110 receives signals from 105C and 105D, for example, during winding onto the first winding bobbin 7A, the controller 110 switches the second and third proximity switches]0
The stepping motor 84 is moved so that the cord 5 is wound between 5A and 105B (between the flanges 7a and 7a).
The movement of the traverse pulley 81 is controlled by the control. At the same time, the controller 110 receives the joint detection signal F and automatically changes the winding of the cord 5 from one winding bobbin currently being wound to the other winding bobbin.

Note that 106 is a cutter device that cuts near the joint portion 5c and separates the coat 5 wound on the first winding bobbin 7A and the cord 5 wound on the second winding bobbin 7B.

With the above configuration, in the first zone Z1, for example, the cord 5 before the dip treatment, which is fed out from the first cheese 4A, is wound a plurality of times between the pull rolls of the first pull roll device 61, and the tension is It is then cut and then wound several times around the upper and lower dip rolls in the dip tank 11 to perform the first step of dip processing.

Thereafter, it is guided into the first oven 15 for drying and heating. In the first oven 15, the cord 5 is wound a plurality of times between upper and lower turn rolls 19, 23, and the adhesive is dried and stretched and heat-set.

The rod 5 coming out of the oven 15 is then set under tension by the first tension control device 15.
After that, the coat 5 is wound several times between the rollers 27 and 31 for cooling, and the temperature of the coat 5, which had been rising due to drying and heating in the oven 15, is reduced to a predetermined temperature at which the physical properties of the cord do not change. cooled down to

After the cord is cooled, it passes through a second pull roll device 62 located between the first zone Z and the second zone Z to the second zone Z.
2.

Thereafter, in the second to fourth zones 22 to Z4, the same operation is performed or the type of adhesive is changed, and the cord 5 coming out from the fourth oven 18 is finally transferred to the automatic winding machine 6. It is designed to be wound onto winding bobbins 7A and 7B.

The winding by the automatic winder 6 is controlled by the controller 110 according to the flowchart shown in FIG.

First, when starting, the cord of the first cheese 4A is dip-processed (step S). and the first cheese 4
At the end of the winding of A, it is determined whether the limit switch 73 has detected the passage of the joint portion 5c formed by connecting the end portion 5a of the cord 5 of the first cheese 4A and the tip portion 5b of the cord 5 of the second cheese 4B. A determination is made (step S,).

When there is a joint detection signal F from the limit switch 73, the time required to change from winding on the first winding bobbin 7A to winding on the second winding bobbin 7B, that is, the bobbin switching time is calculated ( Step S2).

Bobbin switching time・(distance from limit switch 73 to winding position)/'(processing speed) Then, turn on the bobbin switching timer (not shown) (step S), and send the winding bobbin switching signal to the stepping motor 84. The winding bobbins 7A and 7B are output by the operation of the stepping motor 84.
A switching operation is performed (step S).

That is, the tension rod 83 is rotated by the driving of the stepping motor 84, and the movable base 82 moves from the position corresponding to the first take-up bobbin 7A to the second take-up bobbin 7 after the bobbin switching time has elapsed.
It is controlled to move to the winding start position to B.

At this time, since the limit switch 87 is located between the first winding bobbin 7A and the second winding bobbin 7B, the contact 87a of the limit switch 87 is reversed during the movement of the traverse pulley 81. (see Figure 6),
The operator is informed that the second winding bobbin 7A is ready to be wound.

Therefore, it is determined whether or not the bobbin switching operation is completed (step S), and if the switching operation is completed, it is determined whether or not to process the next code (step S6); if not, The heater drive is stopped (step S7),
When continuing processing, continue the code dip processing work. Further, if it is determined in step S that the switching operation is not completed, the bobbin switching operation is continued.

Then, it is determined whether the temperature inside the oven has decreased below a predetermined temperature (Step S8), and if it has not decreased, the determination is repeated; if it has decreased, the exhaust fan is stopped.Step S,), End. do.

(Effect of the invention) Since the invention of claim (1) is constructed as described above, it is possible to automatically and reliably switch the winding bobbin for winding the cord, and to continuously switch between two winding bobbins. You can then wind the cord. Also, since the joint comes at the end of the winding of the winding bobbin, it is easy to dispose of (discard) the joint. Therefore, if there is no joint within the cheese, there will be no joint within the winding bobbin, which can reduce losses in subsequent processes.

The invention of claim (2), as described above, is provided with a limit switch that indicates the winding bobbin on which the wire rod is currently being wound, so that it is possible to prevent winding errors at the start of winding. .
