Description
A METHOD FOR ENABLING THE PRODUCTION MACHINES IN THE CORD PRODUCTION SYSTEM TO BE STOPPED SYNCHRONOUSLY
Field of the Invention
The present invention relates to a method for enabling the production machines in the cord production system to be stropped synchronously during sudden interruptions such as power failure, power loss in yarn twisting machines.
Background of the Invention
End of the batch should be waited for stopping in twisting machines. If it is stopped without waiting the end of the batch, problems occur in twist levels and length differences between the layers. Because of the problems occurring in the production, loss of production is experienced in both power shortage and halts at weekends.
There is no technology about synchronized stops in the current twist machines. When there is a length difference between the twists/layers in reasonable acceptable levels according to its speed, this situation is tried to be stabilized in the cage area behind the weaving machines. However the problems in the high speeds pose bigger problem. Especially, in production speeds with 10000 or more cycles, any stop occurring during production causes non-standard product output.
When the shift system requires stopping on Sunday, non-standard reels are produced since the machines cannot stop synchronously. Besides, same problem also occurs during energy blackout. These cause both production and raw material loss and a significant cost for the fields. In order to avoid this, the production is planned to be finished on Saturday with planning studies but it cannot always be realized.
The synchronized stop not being performed causes interruptions in operation of the system after the machine is activated again. The said interruptions cause material loss and yield losses in the production. Chinese Utility model no CN2782723, an application known in the state of the art, discloses an apparatus which stops the warping machine in case of power cut off. When the power cuts off, the stopper in the three servo motors brakes suddenly, and the yarn frame, traction roller and the warp beam electromagnetic brake also brake one after another. Three servo motors are stopped synchronously with the servo controller. Therefore the warping machine is stopped fast and synchronously.
Summary of the Invention
The objective of the present invention is to provide a cord production system developed to eliminate the sudden power loss problems occurring in the system such as power blackout, and a method for enabling the manufacturing machines to be stopped synchronously.
Another objective of the present invention is to provide a cord production system which enables to operate without any problem when the motors receive energy again and to obtain a twisted cord reel within the tolerances of the final product without any problem in the quality, and a method which enables the production machines to be stopped synchronously. Detailed Description of the Invention
The inventive "a cord production system and a method for enabling the production machines to be stopped synchronously" developed to fulfill the objectives of the present invention is illustrated in the accompanying figures, wherein
Figure 1 is the schematic view of the cord production system.
The components shown in the figures are each given reference numerals as follows:
1. Cord production system
2. Spindle motor
3. Winding cylinder
4. Guide plate
5. Metal rod
6. Mechanical unit
7. Control unit
K. Cord
B. Reel
V. Power/electric source
The inventive cord production system (1), which enables the production machines to stop synchronously in cases of sudden halts such as power blackout, power loss in the yarn twisting machines, comprises
- at least one spindle motor (2) which provides the motion twisting the yarns while becoming cords,
- at least one winding cylinder (3) which enables the cord (K) that is produced to be wound around a reel (B) and held properly,
- at least one guide plate (4) which is close to the winding cylinder (3) from its side surface, and enables the cord (K) to be wound on the winding cylinder (3) properly,
- at least one metal rod (5) which is connected to the guide plate (4), and functions as a handle for removing the guide plate (4) from the winding cylinder (4),
- at least one control unit (7) which sends a signal to the winding cylinder (3) to stop by detecting the power blackout in the system, and sends a signal to at least one mechanical unit (6) enabling the metal rod (5) to be moved thus enabling the guide plate (4) to be removed.
The method for stopping the inventive cord production methods synchronously comprises the steps of
- the control unit (7) detecting the power loss/blackout in the cord production system (1),
- generating reverse acceleration in the winding cylinder (3) by giving start- stop transmission to the winding cylinder (3) by the control unit (7),
- stopping the winding cylinder (3) synchronously with the spindle motor (2) of the control motor (7) by means of the reverse acceleration,
- removing the cord (K) from the guide plate (4) via a mechanical unit (6) with a signal sent from the control unit (7), in order to prevent the cord (K) from rambling around the winding cylinder (3) during stopping the winding cylinder (3),
- reactivating the system (1) after the power loss/blackout is recovered. In the preferred embodiment of the invention, the mechanical unit (6) used to remove cord (K) from the guide plate (4) by pushing the metal rod (5) connected to the guide plate (4) is a pneumatic cylinder.
In the preferred embodiment of the invention, the control unit (7) automatically activates the winding cylinder (3) upon the system (1) receives the power again.
In the preferred embodiment of the invention, stopping time information can be entered into the control unit (7) based on the speed and style information. The inventive method is essentially comprised of two parts. In one of the said methods, the winding cylinder (3) is enabled to be stopped synchronously with the spindle motor (2) by giving a start-stop transmission by the control unit (7). While doing this, a reverse acceleration parallel to the position of the spindle motor (2) is provided, and start-stop signals are given to the brake mechanism of the winding cylinder (3) so that synchronous stop of the winding cylinder (3) with the spindle motor (2) is enabled.
The brake discs which the winding cylinder (3) has are adapted to the inventive system (1). Within the scope of the invention, since the number of stop- start signals is planned to be limited for the life of the machine, it is not expected that this will affect the brake disc destructively.
In the other control part, by means of a mechanical pneumatic system the cord (K) is released from the guide plate (4) during synchronous stop, the cord (K) is prevented from rambling around the winding cylinder (3) during synchronous stop. This process is realized via a pneumatic cylinder as soon as the power blackout is experienced or a stop signal is received by the system. The pneumatic cylinder moves the metal rod (5) upwards. In the meantime, the metal rod (5) which is under the route of the twisted cord (K) moves the twisted cord (K) upwards and releases it from the guide plate (4), and the guide plate stays idle for a short time in which the motors stop after the energy blackout or stop signal is received. Therefore, no extra complexity is experienced in the wound reel.
In case the twisted cord (K) cannot be released, the cord (K) slips on the winding cylinder (3). By means of the inventive system, this slippage and the irregular winding to be caused by the slippage can be prevented.
By means of the inventive method, at the end of the day, power blackout or production stopping can be overcome without experiencing twist loss of the final cord (K) or a problem such as going out off the track by loosing tension.
In case of power blackout or shift end, the production machines can be stopped synchronously and product loss will not be experienced. For this reason limitations planned before will not be necessary. By means of the inventive system, the festoon developed to prevent rupture in the warps during stopping provides the required accumulated yarn. Furthermore, the
horizontal rotational move that can affect the winding quality during stopping is prevented by removing the cord from the guide plate.
Within the framework of these basic concepts, it is possible to develop a wide variety of embodiments of the inventive method for enabling the production machines to be stopped synchronously in the inventive cord production system (1). The invention cannot be limited to the examples described herein; it is essentially as defined the claims.
