Claims
- 1. Servicing apparatus for a plurality of spinning machines comprising:
- servicing means for servicing spinning assemblies of the spinning machines, said servicing means including function elements for carrying out servicing operations,
- moving means for moving said servicing means to respective servicing positions adjacent the respective spinning assemblies to be serviced,
- program control means for controlling switching sequences and switching times of drives for said function elements,
- said program control means including a plurality of control programs which are distinguished from one another as to switching sequence and/or switching times, whereby different spinning machine operating conditions can be accommodated by said servicing means,
- and program switch control means for switching said program control means from one control program to another.
- 2. Servicing apparatus according to claim 1, wherein said program switch control means includes means for switching said program control means in dependence on the operating conditions of the spinning machine of the spinning assembly to be serviced.
- 3. Servicing apparatus according to claim 2, wherein said program switch control means includes a selector switch at the servicing means for setting a program appropriate to the spinning machine to be serviced.
- 4. Servicing apparatus according to claim 3, wherein each spinning machine is provided with a switching element that sets the selector switch in accordance with the operating condition of the spinning machine.
- 5. Servicing apparatus according to claim 4, wherein each spinning machine in the region of an entrance for the servicing means has one of said switching elements for setting the selector switch of a passing servicing means.
- 6. Servicing apparatus according to claim 5, wherein said switching element includes one of mechanical, optical, acoustical, pneumatic, and electrical means for transmitting a signal to the selector switch.
- 7. Servicing apparatus according to claim 1, further comprising:
- disturbance responsive control means for controlling said moving means to move said servicing means to move said servicing means to a service position adjacent a spinning assembly in response to detection of an operational disturbance at said spinning assembly, whereby those spinning assemblies exhibiting an operational disturbance can be serviced,
- step-by-step control means for controlling said moving means to move said servicing means to respective servicing positions adjacent respective spinning assemblies in a predetermined sequence, where preventive maintenance servicing operations can be carried out by said servicing means,
- and switchover means for switching control of said moving means between said disturbance responsive control means and said step-by-step control means.
- 8. Servicing apparatus according to claim 7, wherein said switchover means includes:
- travel path responsive means for switching to said step-by-step control means in response to traversal of a predetermined travel path by said servicing means,
- and time responsive means for switching to said disturbance responsive control means after a predetermined time interval.
- 9. Servicing apparatus according to claim 2, wherein said spinning assemblies are open end spinning assemblies, and wherein said servicing means includes yarn piecing means for performing yarn piecing operations at said spinning assemblies.
- 10. Servicing apparatus according to claim 7, wherein said switchover means includes a double throw switch for switching between said disturbance responsive control means and said step-by-step control means.
- 11. Servicing apparatus according to claim 2, wherein a common interconnected guide track is provided for accommodating travel of said servicing means adjacent a plurality of separately drivable open end spinning machines, each of said spinning machines including a plurality of open end spinning assemblies, and wherein said servicing means includes means for performing a thread piecing operation.
