Definitions

• the present invention relates to a balloon diameter control unit which enables the balloon diameter to be directly controlled by means of the position sensors in twisting machines making direct cabling, and thus to decrease the energy consumption.
• the first step performed in cord fabric production is to twist yarns to be used in the structure of the cord fabric. It was determined that the balloon effect occurring during this twisting process causes more energy consumption than required.
• the current twisting machines making direct cabling performs twisting process of one outer yarn and one inner yarn on a regulator. Cabling is a process to provide more elasticity to two cords.
• the twisted yarns (cords) are placed inside the tire by being cabled in two or more layers, and this provides elasticity to the tire. While performing this, the inner yarn is fed towards the regulator from the position called pot vessel.
• the outer yarn is fed from the creel.
• the yarn fed from the creel enters into the regulator with the yarn fed from the pot, and the twisted yarns are cabled on top of each other, and then the product is wound around the winding cylinder.
• the outer yarn Before the outer yarn is fed to the regulator, it enters into the spindle motor, and the yarn coming out of the disc on the spindle motor is directed between the pot and the sheet limiting the position via the yarn twisting plate.
• a balloon is formed between the pot vessel and the sheet.
• a control about balloon diameter is not practiced.
• the balloon is formed depending on the speed applied in the machine and the dtex value of the product, and comprises the large part of the energy consumption. The energy consumption increases with the increasing dtex value. Increase in speed and dtex caused by the centrifugal effect causes a direct increase in the energy consumption.
• no precaution can be taken against breaking or tension changes.
• German Patent document no DE4220824 an application known in the state of the art, twister for pneumatic yarn spinning from fiber bundle- has two -twisters in series with polygonal yarn passage and final balloon limit.
• the twister has two twisting units. Their jets inject compressed air into yarn channels which act as eddy chambers, in series behind each other.
• a yarn balloon control is at the outlet of the second twister.
• the channel passing through, as the yarn passage, is expanded into a polygonal cross section. The structure restricts the movement of the developing yarn, so that it travels on a straight line with limited ballooning movement.
• the Great Britain patent document no GB38901 discloses improvements in spinning and/or twisting textile fiber and artificial silk.
• spinning or twisting threads of natural fibers or of artificial silk balloon forming and tangential breaking during the yarn passing through the rotating bobbin is enabled to be determined.
• an adjustable yarn guide By means of an adjustable yarn guide, the balloon formation is controlled.
• the biggest problem in applications known in the state of the art is that the outer yarn feeding system is only connected to brake.
• the brake is not an equipment that can response any problem occurring in outer yarn feeding. Furthermore, it is ineffective against the unnecessary loosening or narrowing occurring in case of balloon formation. Balloon formation or the size of the balloon in the final product is ineffective after a certain point. It is expected that the said required maximum values are provided and it can adapt to the changing conditions after that.
• the present objective of the present invention is to provide a balloon diameter control unit in order to control the diameter of the balloon formed during twisting with a feedback created by sensors in regulator+spindle motors and thus to minimize the energy consumption.
• Figure 1 is the schematic view of the inventive balloon diameter control unit
• the inventive balloon diameter control unit (1) comprises a control card (2) which receives the information about the coming angle of the outer yarn (8) sent to the twisting member (T) via sensors (3) located on the regulator (4) and the spindle motor (5), and therefore which controls the outer yarn feeding motor (6) in order to arrange the properties of outer yarn (8) such as its angle, tension that is effective in determining the balloon diameter value.
• the control card (2) arranges the outer yarn transmission speed of the outer yarn feed motor (6) with feedback in accordance with the information it receives from the sensors (3).
• the angle difference between the outer yarn (8) exiting from the spindle motor (5) and entering the regulator (4) determines the status of the balloon around the pot. If this angle is above a certain level, the outer yarn (8) starts to wrapped around the disc surrounding the spindle motor (5), and this causes the balloon formed around to pot to become larger unnecessarily.
• a control card (2) controls the outer yarn feeding motor (6) according to the angle values of the regulator (4) and the spindle motor (5).
• the said control card (2) receives the required angle information from the regulator (4) and the spindle motor (5) via the sensors (3) located thereon, and controls the balloon. Therefore, the diameter of the balloon is continuously kept at the desired level.
• Feeding outer yarn (8) is provided with the outer yarn (8) to be dispersed to the regulator /4) during the rotation of the spindle motor (5) in the state of the art.
• the outer yarn feeding motor (6) enabling the outer yarn (8) to be fed to the twisting member (T) is preferred as a step motor in order to perform this feeding in a controlled way with pulses given to the motor.
