This electronically controlled mini sample warping machine or winding machine 2
The control portion can be divided into blocks 71 to 81 as shown in FIG. Below, we will explain the operation of each block. 71 is a program setting device that selects 10 types of yarn from 0 to 9, sets the number of turns,
Configure repetition settings. This setting is performed using ten key switches 0 to 9, ↑ switch, ↓ switch, transition switch, ( ) switch, end switch, CLR switch, and paper feed switch provided in the program setting device 71. The set program can be printed on a small printer, and the contents of the program can be displayed using LEDs such as address, presence or absence of parentheses, number of turns, and number of repetitions. There is also a switch to select write, run, and call operations, and when operating, it is possible to display the preset contents and the operating status, and when calling,
Programs can be modified and operating conditions can be modified. The controller 72 is connected via yarn type, yarn change, and count up signals, and sequentially repeats a preset program while transmitting and receiving these signals. The content of the program uses four arithmetic formulas, for example, yarn type 1
10 times, yarn type 2 5 times, yarn type 3 7 times, repeat these 3 times, then yarn type 4 6 times, yarn type 5
The program to wind twice is (1x10+2x5+3x7) ³ +
It can be applied to the formula 4x6 + 5x2. Of course ( )
Use many times {[(1x2+2x3) ³ +1x4] ⁵ +2x6}
It is also possible to create a program called ⁷ +3x5. Furthermore, once a program is set, it is protected by a backup battery unless the program is changed. The controller 72 is a part that controls this winding machine, and controls the contents of the program set by the program setting device 71 and the density setting device 75.
A take-up motor drive circuit 73, a feed motor drive circuit 74, a take-up motor clutch brake drive circuit 78, and a take-up plate are connected to the controller 72 according to the operation switch 76, select switch 77, limit switch 80, and sensor 81. This is to control the clutch brake drive circuit 79.
The take-up motor drive circuit 73 controls starting and stopping of the take-up motor. Feed motor drive circuit 7
Reference numeral 4 controls forward/reverse rotation and starting/stopping of the feed motor 16. The density setting device 75 is a switch that can change the yarn winding pitch, and is composed of a digital switch that can select from 255 hexadecimal numbers from 01 to FF. The winding pitch is
It is 0.01mm to 2.55mm. The operating switches 76 are operating switches other than the density setting device 75 and the select switch 77, and are a group of switches that control the operation of the winding machine. These switches include a start setting switch, a start switch, a stop switch, a power switch, a winding plate switch, a +-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 can select from 10 types from 0 to 9. The clutch brake drive circuit 78 for the take-up motor is a drive circuit for a clutch brake that transmits the rotation of the take-up motor to the input side of the clutch controlled by the clutch brake drive circuit 79 for the take-up plate.

9 is a clutch brake drive circuit 78 for the winding motor.
This is a drive circuit for a clutch that transmits the rotation of the winding motor transmitted by the clutch controlled by the winding motor to the winding plate, and a brake that stops the winding plate. There are two types of limit switches, a + side limit switch and a - side limit switch, which sense the limit position when the winding plate moved by the feed motor moves to the + side and - side. sensor 81
The sensor has a mechanism that counts the rotation of the winding plate, a sensor that functions as a reference pulse for starting the movement of the feed motor, a sensor that always stops the winding plate in a fixed position, and a sensor that functions to start winding. There are three types of sensors that notify the location, all of which are composed of 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 flow chart.

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 the yarn types 0 to 9 have been set, and the start setting switch is turned on, if the winding plate is at the - side limit position, the winding plate will move to the left. After rotating the feed motor and moving it to the - side limit position and stopping it, from now on, rotate the feed motor so that the winding plate moves to the right, and stop it 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 to start moving the feed motor at a speed that matches the density set by the density setting device 75, and the winding plate moves to the right. It rotates as it moves, 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 from the program setter 71 is received. 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 is generated 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 0 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 take-up plate is turned on. When the yarn type set by the select switch and the yarn type signal sent from the program setting device 71 match, 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 do not match and the position sensor turns on. In this state, even if a change signal sent from the program setting device 71 is received, the take-up motor clutch is not turned off and the take-up motor brake is not turned on.
The feed motor also receives the ON signal from the feed sensor and rotates so that the winding plate moves to the right, moves to a predetermined amount of movement that matches the density set with the density setting device, stops, and then starts feeding again. It repeatedly rotates in the same direction upon receiving the ON signal from the sensor. This condition prevents the winding plate from moving too far to the left.
It continues until the side limit switch is turned on, after which it returns to the state of waiting for the start setting switch to be turned on. The feed sensor also serves as a count-up signal, which is an output signal to the program setting device. Through these operations, when the select switch does not set any of the yarn types 0 to 9, it is possible to stop the feed motor and the winding plate every time the change signal is sent from the program setting device 71. When any one of yarn types 0 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 does not set any of the yarn types 0 to 9, if you change the yarn type at each change signal, the entire process can be completed with one movement of the winding plate to the + limit switch position. , if any one of yarn types 0 to 9 is set, first move the winding plate to the + limit switch position to wind the same type of yarn, and from the second time onwards, wind a different type of yarn. This operation is repeated until all yarn types are wound, completing the entire process.
Furthermore, by changing the mounting state of the winding plate by 90 degrees and repeating these operations, it becomes possible to wind the yarn at a different angle from the previous winding direction by 90 degrees.

The yarn types used in this device are not limited to 10 types from 0 to 9, and the density setting device may also be 255 types or less or more. The feed motor may also be a pulse motor or a servo motor 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 not only a photoelectric type but also a magnetic type or a mechanical type sensor.
