Abstract
Abstract A method of and apparatus for controlling spinning machines comprising circulating a working machine having a detector along a rail for monitoring the running conditions of the spinning machines in which a transmitter provided in the working machine transmits a first information signal indicating the nature of possible abnormal conditions of each spinning machine to a remote station having a receiver and a computer. In the receiver, a second information signal is generated and successively stored in registers depending on the nature of the abnormal conditions in accordance with the first information signal received. The computer reads the contents of the registers only when an interrupt signal is generated which indicates that an abnormal condition has occurred in a particular spinning machine. The computer memory tabulates these data and updates the data each time the working machine circulates around the spinning machines. Thus, by counting the data in the memory, the running conditions of the spinning machines can be effectively monitored. Furthermore, the number of inputs to the computer can be effectively reduced by limiting the input data to the computer to a minimum.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
207 words
A method of controlling spinning machines comprising the steps of: providing at least one rail and transmission lines around a plurality of spinning machines in blocks; circulating at least one working machine having a detector along said rail for monitoring the running conditions of said spinning machines; detecting said running conditions of each spinning machine by said detector and transmitting a first information signal having unique characteristic portions indicative of the nature of possible abnormal conditions of each spinning machine in accordance with the detected signals through said transmission lines; receiving said information signal at a remote central station having data receiving and registering means and a data processor; generating a second information signal having unique characteristic portions indicative of the nature of abnormal conditions of spinning machines in accordance with the first signal and registering successively said characteristic portions of said second signal into registers; reading the contents of registers into said data processor successively during one cycle of monitoring operations only when an interrupt signal, indicating that the occurrence of an abnormal condition, is generated; tabulating the data thus read in the data processor, and; updating the data in a memory in the processor each time said working machine moves once around the spinning machines.
Claim 2
Independent Claim
207 words
A method of controlling spinning machines comprising the steps of: providing at least one rail and transmission lines around a plurality of spinning machines in blocks; circulating at least one working machine having a detector along said rail for monitoring the running conditions of said spinning machines; detecting said running conditions of each spinning machine by said detector and transmitting a first information signal having unique characteristic portions indicative of the nature of possible abnormal conditions of each spinning machine in accordance with the detected signals through said transmission lines; receiving said information signal at a remote central station having data receiving and registering means and a data processor; generating a second information signal having unique characteristic portions indicative of the nature of abnormal conditions of spinning machines in accordance with the first signal and registering successively said characteristic portions of said second signal into registers; reading the contents of registers into said data processor successively during one cycle of monitoring operations only when an interrupt signal, indicating that the occurrence of an abnormal condition, is generated; tabulating the data thus read in the data processor, and; updating the data in a memory in the processor each time said working machine moves once around the spinning machines.
Claim 3
Dependent Claim
28 words
The method set forth in claim 1 wherein said characteristic portions consist of signals corresponding to a position of a spindle, yarn breakage, yarn-tying failure and empty spindle.
Claim 4
Dependent Claim
60 words
The method set forth in claim 1 wherein the method further comprises: counting the number of abnormal conditions for each spindle in accordance with the data stored in the memory of the data processor and indicating the counting on a displaying device so that said working machine is quickly accessible to a particular spinning machine to be taken care of.
Claim 5
Dependent Claim
49 words
The method set forth in claim 1 wherein said method further comprises: clearing a spinning counter each time one block of spinning machines passes by and calculating each spinning number by said data processor in accordance with the contents of a value of a spinning counter and block numbers.
Claim 6
Dependent Claim
47 words
The method set forth in claim 1 wherein said method further comprises: rewriting data indicative of the nature of abnormal conditions of spinning machines to other normal information in the memory of the data processor when a particular spinning machine which has had a failure is restored.
Claim 7
Dependent Claim
179 words
An automatic spinning machine monitoring system which comprises: at least one working machine having a detector for detecting the running conditions of each spinning machine and the passage of spindle positions; at least one rail and transmission lines for circulating said working machine along said rail; data transmission means connected to said detector for receiving detected signals and for generating and transmitting a first information signal having unique characteristic portions corresponding to the nature of possible abnormal conditions of each spinning machine through said transmission lines; receiving and registering means having a plurality of input registers and a spinning number counter coupled to said transmission lines for receiving said first information signal and selectively registering said characteristic portions of said first signal into said registers, and; a data processor having a memory means and coupled to said receiving and registering means for reading only data indicative of the nature of existing abnormal conditions of spinning machines from said registers and for processing said data so as to indicate one or more particular spinning machines to be taken care of.
Claim 8
Dependent Claim
179 words
An automatic spinning machine monitoring system which comprises: at least one working machine having a detector for detecting the running conditions of each spinning machine and the passage of spindle positions; at least one rail and transmission lines for circulating said working machine along said rail; data transmission means connected to said detector for receiving detected signals and for generating and transmitting a first information signal having unique characteristic portions corresponding to the nature of possible abnormal conditions of each spinning machine through said transmission lines; receiving and registering means having a plurality of input registers and a spinning number counter coupled to said transmission lines for receiving said first information signal and selectively registering said characteristic portions of said first signal into said registers, and; a data processor having a memory means and coupled to said receiving and registering means for reading only data indicative of the nature of existing abnormal conditions of spinning machines from said registers and for processing said data so as to indicate one or more particular spinning machines to be taken care of.
