Claims
- 1. A process for textile fiber material storage between operating components of spinning mill machines, the process comprising:delivering textile fiber material by a delivering operating component of a spinning mill machine to a storage facility located between the delivering operating component and a removing operating component of the spinning mill machines; removing the textile fiber material from the storage facility using the removing operating component; wherein one of said delivering and removing operating components is driven by a high-dynamic drive system and the other of said delivering and removing operating components is driven by a low-dynamic drive system; measuring simultaneously and continuously to quantify the delivered textile fiber material to the storage facility and the removed textile fiber material from the storage facility; calculating continuously a difference value between the quantity measurement of the delivered textile fiber material to the storage facility and the quantity measurement of the removed textile fiber material from the storage facility; and measuring the difference value against a standard quantity value and using that measurement to control the low-dynamic drive system using a controller.
- 2. A process as in claim 1, wherein the storage facility is between said delivering operating component of the spinning mill machines, which delivers the textile fiber material at an essentially constant speed, and the operating component which is driven by the high-dynamic drive system.
- 3. A process as in claim 1, wherein the quantity measurement of delivered textile fiber material is determined by measuring signals of a signal generator disposable to a shaft of one of the high-dynamic and low dynamic drive systems which drives the delivering operating component delivering the textile fiber material, and the quantity measurement of removed textile fiber material is determined by measuring signals of a signal generator disposable to a shaft of the other of the high-dynamic and low dynamic drive systems which drives the removing operating component removing the textile fiber material.
- 4. A process as in claim 3, wherein the signals generated by the signal generators disposable to the shafts of the operating components which deliver and remove the textile fiber material are counted as count input using a counter which measures the count input against the standard quantity value that is preset.
- 5. A process as in claim 4, further comprising calculating the difference between the count input and the standard quantity value; and, depending on a preset threshold, accordingly adjusting the low-dynamic drive system by sending a signal from the counter to the controller of the low-dynamic drive system.
- 6. A process as in claim 5, further comprising adjusting the low dynamic drive system depending on a plurality of threshold values allowing for control of the rate of rotation at different rotational speeds.
- 7. A process as in claim 5, further comprising measuring the difference among at least two count inputs arising successively, and comparing that number against a threshold value to allow the rate of rotation to be controlled.
- 8. A process as in claim 7, further comprising measuring the difference among at least two count inputs arising successively, and comparing that number against a threshold value to allow the rate of rotation to be controlled proportional to the difference.
- 9. An apparatus for textile fiber material storage between operating components of spinning mill machines, said apparatus comprising:a storage facility; a feed operating component for feeding the fiber material to said storage facility; a removing operating component for removing the fiber material from said storage facility: a delivery operating component down stream of said removing operating component for delivering the fiber material from the spinning mill machine; wherein said removing operating component is driven by a high-dynamic drive system and said delivery operating component is driven by a low-dynamic drive system; a signal generator for determining the quantity of delivered fiber material disposed proximal to an entry of the storage facility; a signal generator for determining the quantity of removed fiber material disposed proximal to an exit of the storage facility; a counter to which both said signal generators are connected for calculating continuously a difference value between the measurements of said signal generators; and a controller to which said counter supplies said difference value for controlling said low-dynamic drive system for the respective operating component.
- 10. An apparatus as in claim 9, wherein said signal generator for determining the quantity of delivered fiber material is operationally configured with said feed operating component and said signal generator for determining the quantity of removed fiber material is operationally configured with said removing operating component.
- 11. An apparatus as in claim 10, wherein said feed operating component is driven by a constant drive system.
- 12. An apparatus as in claim 10, wherein said signal generators are absolute value devices or incremental generators.
- 13. An apparatus as in claim 9, wherein said storage facility is disposed between said feeding operating component of the spinning mill machines which delivers the textile fiber material at an essentially constant speed, and said removing operating component which is driven by the high-dynamic drive system.
- 14. An apparatus as in claim 13, wherein said motor for the low-dynamic drive system is an asynchronous motor.
- 15. An apparatus as in claim 9, wherein said low-dynamic drive system and said high-dynamic drive system are driven by motors.
