The density setting device 75 is a switch that can change the yarn winding pitch, and is a hexadecimal number of 255 from 01 to FF.
It consists of a digital switch that allows you to select the type. The winding pitch is 0°01 mm to 2.55 mm.

The operation switch 76 is a group of operation switches other than the density setting device 75 and the select switch 77 that control the operation of the winding machine. These switches include a start setting switch, starting switch, stop switch, power switch, winding plate switch, ten-correction switch, and the like. The select switch 77 is a switch for selecting the yarn type signal sent from the program setting device 71, and
It is possible to select from 10 types of tn up to 9. The take-up motor clutch-brake drive circuit 78 is a clutch-brake drive circuit that transmits the rotation of the take-up motor to the input side of the clutch controlled by the take-up plate clutch brake drive circuit 79. Brake drive circuit 79
is a drive circuit for a clutch that transmits the rotation of the take-up motor transmitted by the clutch controlled by the take-up motor clutch-brake drive circuit 78 to the take-up plate, and a brake for stopping the take-up plate. There are two types of limit switches, a + side limit switch and a one side limit switch, and these are switches that sense the mint position when the winding plate is moved by the feed motor. The sensor 81 includes a mechanism that counts the rotation of the winding plate, a sensor that has the function of a reference pulse for starting the movement of the feed motor, a sensor that always stops the winding plate at a fixed position, There are three types of sensors that notify the starting position, all of which are photoelectric sensors.

FIG. 5 is a time chart of the operation of this winding machine, and FIG. 6 is a flow chart showing the operation of this winding machine. The operation of the winding machine will be explained below based on this time chart and flowchart.

First, by turning on the power switch, which is one of the operation switches, the winding motor rotates, although it is not shown in this time chart. Next, when the select switch is off, that is, none of yarn types O to 9 have been set, and the start setting switch is turned on, if the winding plate is at the limit position, the winding plate will move to the left. After rotating the feed motor to move it to the one-side limit position and stopping, rotate the feed motor so that the winding plate moves to the right, and stop when the start position sensor turns on. During this time, both the take-up motor clutch and the take-up plate clutch are off, and the take-up motor brake and the take-up plate brake are both on. Next, when the start switch is turned on, the take-up motor clutch and the take-up plate clutch are both turned on, the take-up motor brake and the take-up plate brake are both turned off, and the take-up plate starts rotating. Further, the feed motor receives an ON signal from a feed sensor that generates a reference pulse for starting the movement of the feed motor at a speed that matches the density set by the density setter 75, and the winding plate moves to the right. It rotates like this, and stops when it moves to a predetermined amount of movement that matches the density set by the density setting device. Next, upon receiving an ON signal that generates a reference pulse, it starts rotating in the same direction again, and this operation is repeated until the stop switch is turned ON or a change signal is received from the program setter 71. At this point, both the take-up motor clutch and the take-up plate clutch are off, the take-up motor brake is on, and the take-up plate brake moves the take-up plate into position, which occurs every time the take-up plate rotates. In response to the on signal from the fixed position sensor, the winding plate is turned on and the winding plate stops. The winding plate switch is a switch to keep the winding plate in a free state. While this switch is on, the winding plate brake is turned off and the winding plate is in a free state, and the winding plate is kept in a free state. It becomes possible to fix the thread to. Next, when the select switch is set to one of yarn types O to 9 and the start switch is turned on, the take-up motor clutch is turned on, the take-up motor brake is turned off, and the second take-up plate is turned on. When the yarn type set by the select switch matches the yarn type signal sent by the program setting device 71, the winding plate clutch is turned on and the winding plate brake is turned off. The winding plate starts rotating, and stops when these signals become inconsistent and the fixed position sensor turns on.In this state, even if a change signal sent from the program setting device 71 is received, the winding plate will not start rotating. The clutch for the take-up motor is turned off, the brake for the take-up motor is not turned on, and the feed motor also receives the on signal from the feed sensor and rotates so that the take-up plate moves to the right, and the density setting device is set. It moves to a predetermined amount of movement that matches the density and then stops.
It receives the ON signal from the feed sensor again and repeats rotation in the same direction. This state continues until the + side limit switch, which prevents the winding plate from moving too far to the left, is turned on, and after it is turned on, the machine returns to the state where it is waiting for the start setting switch to be turned on. The feed sensor also serves as a count amplifier signal that is an output signal to the program setting device. Through these operations, when the select switch is not set to any of the yarn types O to 9, it is possible to stop the feed motor and winding machine every time a change signal is sent from the program setting device 71. When any one of yarn types O to 9 is set, it is possible to wind only the yarn that matches the yarn type signal sent from the program setting device. In other words, if the select switch is not set to any of the yarn types O to 9, if you change the yarn type at every change signal, the entire process will be completed with one movement of the winding plate to the + limit switch position. However, if any one of yarn types O to 9 is set, the same type of yarn is wound in the first movement of the winding plate to the + limit switch position, and a different type of yarn is wound in the second and subsequent movements. Winding and repeating this operation until all yarn types have been wound to complete the entire process. Moreover, by changing the mounting state of the winding plate by 90 degrees and repeating these operations, it becomes possible to wind the yarn by changing the angle of 90 degrees from the previous winding direction.

The yarn types used in this device are not limited to 10 types from θ to 9, and the density setting device may also be 255 types or less or more. The feed motor may also be of the pulse motor or servo motor type as long as it can move up to the amount of movement and stop in accordance with the density set by the density setting device. Each drive device may be a semiconductor using a transistor, a thyristor, etc., or a relay using electromagnetic force, and each sensor may be a magnetic or mechanical sensor, not limited to a photoelectric type.
