摘要： PROBLEM TO BE SOLVED: To provide a centralized cotton-gathering apparatus in a spinning machine, capable of shortening a cotton-gathering operation time while operating the spinning. SOLUTION: A fleece or the like supplied from a roller part at the time of yarn breakage is sucked by a pneumatic device installed in each spinning machine frame, and temporarily stored in a cotton-gathering room of a pneumatic apparatus. The fleece or the like stored in each of the cotton-gathering room is gathered in a centralized cotton-gathering apparatus through a branched duct connected to the cotton- gathering room, and a main duct. A signal for demanding the cotton gathering is outputted to the centralized cotton-gathering apparatus when the spinning operation is stopped without the stopping by the abnormality of the spinning machine frame. The cotton-gathering operation of the fleece or the like stored in the cotton-gathering room is certainly carried out not only at the stopping time for doffing but also at a prescribed cycle even under operation of the spinning machine frame. The centralized cotton-gathering apparatus preferentially carries out the cotton-gathering operation according to the operation stop of the spinning machine frame when the cotton- gathering period in the prescribed cycle coincides with the cotton gathering period according to the operation stop of the spinning machine frame.

摘要： PURPOSE:To prevent the end of a thread from the end face of a package in a spinning machine such as, for example, an open-end fine spinning machine, by moving a cradle arm upward after a predetermined time being elapsed from occurrence of thread breakage to isolate the package from a winding drum. CONSTITUTION:In a device for preventing the end of a thread from dropping upon thread breakage from the end face of a package P which is rotatably supported by an cradle arm 11 so that it is made into contact with and driven by a winding drum 12 which continues to rotate even during thread breakage, a thread breakage detecting device 31 detects a thread breakage to issue a thread breakage signal, and therefore, a cradle arm 11 is moved upward after the lapse a predetermined time from the time when the thread breakage signal is generated, to isolate the package P from a winding drum 12. The predetermined time is the time period until the time just after the thread end has passed a nip section, and is determined by dividing an averaged thread path length from the thread breakage detecting device 31 to the nip section with a winding speed. Thus, even after thread breakage, a thread having an end is made into contact with the nip section in the package P, thereby the dropping of the thread end from the end face of the package P may be surely prevented.

摘要： PURPOSE:To shorten the moving time and the smooth moving motion of a doffing bar by moving the doffing bar from the intermediate position through nearly shortest path to the following arranging position. CONSTITUTION:A pantagraph mechanism 11 constituting a bobbin change apparatus is stopped at the intermediate position in a state in which a ring 22 is contacted with a stopper 28 arranged in the moving focus by the pressure of an air cylinder 20. When the intermediate position control is removed, solenoids SOL1 and SOL2 are demagnetized by a control computer C and a change over valve 36 is changed over from the evacuating position to neutral position. Then, air pressure is fed to two chambers of the air cylinder 20 and the difference in pressure between two chambers is decreased and pressurizing force operated from the ring 22 to the stopper 28 is relaxed while engaging the ring 22 with the stopper 28. The stopper 28 is evacuated from this state and the change over valve 36 is returned to the evacuating position. The degree of relax of pressurizing force acting on the stopper 28 from the ring 22 is properly set by a pressure reduction valve 37.

摘要： PURPOSE:To reduce the time required for completion of a series of cop exchange operations in a cop exchanger. CONSTITUTION:A cop exchanger moves a doffing bar 10 through a pantograph mechanism in the vertical direction and the pantograph mechanism is driven by a power cylinder converting the rotatory power of a motor to a reciprocating motion of a drive shaft. The whole body of the pantograph mechanism is rotated around the drive shaft in the direction in which it approaches or goes away from a spinning machine frame. The position of the doffing bar 10 is determined by CPU based on signals respectively sent from a rotary encoder sending out a signal corresponding to the vertical displacement amount of the doffing bar 10 and a detection sensor for detecting the relative position of the pantograph mechanism to the spinning machine. If the doffing bar 10 is arranged to a preliminarily determined prescribed position during the course of an operation of the rotational mechanism of the power cylinder or the pantograph mechanism, the operation of the other mechanism is made to start. Thus, the vertical movement of the doffing bar 10 and the rotational motion of the whole body of the pantograph mechanism are simultaneously performed.

摘要： PURPOSE:To surely stop a doffing bar at a specific suspension position even in the case of occurrence of wear of a sliding part or a driving part or wear of a brake, capable of carrying out drive control of the doffing bar without installing a limit switch. CONSTITUTION:A pantograph mechanism is operated by reciprocation of a driving shaft and a doffing bar is vertically displaced. A rotary encoder outputs a signal corresponding to the displaced amount of the driving shaft. An output signal value and an offset amount of the rotary encoder corresponding to each specific suspension position of the doffing bar is memorized in an operation memory. The offset amount is an output signal value of the rotary encoder corresponding to difference between a specific suspension position and a position of a driving shaft during output of the suspension signal. Every time doffing operation is carried out, the offset amount if obtained in each specific suspension position. A suspension signal output time in the following doffing operation is set based on the offset amounts of plural past times.
