Definitions

  • This invention relates to a spinning machine having a yarn treating carrier provided with a yarn piecing mechanism and a yarn package doffing mechanism therein and moving along a rail provided on a frame of a spinning machine so as at least to stop at a predeter­mined spindle for carrying out a yarn piecing operation to the spindle and a yarn package doffing operation.
  • a spinning machine is provided with a yarn forming and winding device, as unit spindle, including at least a yarn drafting mechanism, a yarn forming mechanism, a yarn detecting mechanism, and a yarn winding mechanism.
  • a plurality of these unit spindles, i.e., the yarn forming and winding devices, are arranged along a longitudinal direction of a frame of the machine with a certain distance interposed therebetween to form a spinning machine.
  • a spinning machine is further provided with a yarn treating carrier including a yarn piecing mechanism and a yarn package doffing mechanism therein. This which moves along a rail provided on a frame of a spinning machine so as at least to stop at a predeter­mined spindle for carrying out a yarn piecing operation to the spindle and a yarn package doffing operation thereof.
  • a yarn treating carrier including a yarn piecing mechanism and a yarn package doffing mechanism is controlled to move to a predetermined position and to stop thereat by detecting a dog provided at a predeter­mined position on the yarn forming and winding device utilizing an encoder which can discriminate an absolute position of the dog and which is provided on the yarn treating carrier.
  • the moving system of the yarn treating carrier as mentioned above is, for example, disclosed in Japanese Unexamined Patent Publication No. 61-266622.
  • the system in order to detect a pattern of a dog when the yarn treating carrier moves along the rail, requires a dog having a significantly elongated portion in a moving direction. Moreover, when the number of dogs is increased, a problem arises in that the number of bit of a dog to be detected will be increased, resulting a broader width of the dog.
  • the moving direction indicating circuit when the moving direction indicating circuit is provided on the yarn treating carrier, it is necessary to transmit information requiring the yarn treatment of each spindle from a machine frame side to the yarn treating carrier while when the moving direction indicating circuit is provided on the machine frame side, it is necessary to transmit the information about a current position at which the yarn treating carrier exists from the carrier to the machine frame as well as to transmit the moving direction indicating signal from the machine frame to the carrier.
  • the yarn treating carrier is controlled in such a way that when the yarn treating carrier detects a spindle at which a yarn treatment operation is required, it stops at the spindle and carries out a predetermined yarn treating operation.
  • the yarn treating carrier selects a moving direction to which it moves next.
  • the moving system of the yarn treating carrier as explained above, is disclosed in, for example, Japanese Unexamined Patent Publication No. 60-47937 and Japanese Unexamined Patent Publication No. 61-60016.
  • the yarn treatment requiring signal is output and indicated at each spindle respectively and, therefore, when the yarn treating carrier detects a spindle at which a yarn treatment operation is required, it shops at the spindle and carries out a predetermined yarn treating operation.
  • the moving system of the yarn treating carrier as explained above is disclosed in, for example, Japanese Unexamined Patent Publication No. 60-47937.
  • the yarn treating carrier successively moves to the spindles adjacently arranged and when it detects the spindle to be treated it stops thereat to perform the necessary yarn treatment.
  • This system has another problem in that it is difficult to make the starting position of the yarn treating carrier deceleration longer than a pitch P formed between the adjacently arranged spindles.
  • the distance for deceleration of the yarn treating carrier is from 100 mm to 130 mm, since a distance is required for acceleration at the start of movement.
  • a yarn treating carrier carries out a yarn piecing operation only in response to a yarn treatment signal output from a spindle, the amount of yarn wound of a yarn package, i.e., a diameter of a yarn package, of each spindle is different from that of another spindle since the amount of the yarn wound on the yarn package is determined by the total time of yarn breakage.
  • the yarn winding operation is sequentially stopped for spindles where the yarn package is full
  • the doffing operation is carried out at the same time in the machine after all of the yarn packages in all spindles are full, or the yarn package doffing operation is carried out when a yarn package of a predetermined spindle in the same machine frame is full.
  • the first object of the present invention is to provide a yarn treatment system in which a detecting device for detecting a yarn treatment signal is commonly used and a position of a yarn treating carrier can be detected precisely and, further, to provide a yarn treating system in which the amount of information to be transmitted between a yarn treating carrier and a machine frame can be reduced.
  • the second object of the present invention to provide a yarn treating system in which an operating pattern of the yarn treating carrier, including a moving direction thereof, can be easily changed if it is moving in one direction.
  • the third object of the present invention is to provide a yarn treatment in which a speed of the yarn treating carrier can be increased.
  • the fourth object of the present invention is to provide a yarn treatment system in which difference in weight of each package that is wound now, can be decreased.
  • a spinning machine having a yarn treating carrier, provided with a yarn piecing mechanism and a yarn package doffing mechanism therein and moving along a rail provided on a frame of the spinning machine so as at least to stop at a predetermined spindle for carrying out a yarn piecing operation and a yarn bobbin doffing operation, and a detecting means for detecting a position of the yarn treating carrier at each spindle portion, the yarn treating carrier controlled so as to perform at least one of a moving operation, a decele­rating operation, and a stopping operation in response to a yarn treatment signal and a detection signal of a position of the yarn treating carrier, each of which being output from each of the spindles.
  • a starting position at which a speed of the yarn treating carrier is decelerated is varied in response to a current moving speed of the yarn treating carrier with respect to the yarn treatment signal output from each of the spindles, a position at which the yarn treating carrier exits, and a distance by which the yarn treating carrier moves.
  • a spinning machine has another technical feature in which the yarn treating carrier is controlled so as to operate the moving, stopping and turning operation in response to a yarn treatment requiring signal, and in accordance with a detection signal the direction of moving of the yarn treating carrier is also controlled.
  • an amount of yarn wound on a yarn package is counted from the time when a yarn winding operation is started, and the yarn treating carrier is controlled so that the yarn treating carrier is preferentially moved to a spindle with a yarn package with a yarn amount smaller than that of other spindles when a plurality of spindles simultaneously require the yarn treatment operation.
