DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a section winding device that continuously winds a bobbin that is divided into a plurality of sections.

First, problems with conventional section winding devices will be briefly explained with reference to the section winding bobbin shown in FIG. Conventionally, a bobbin as shown in Figure 2 was used.
When winding wires in the order of (1), (2), and (3), the conventional traverse mechanism is configured to move according to the length a of the section. When winding ends and moves to the next section, it is necessary to move the bobbin itself in the traverse direction or mechanically move the traverse mechanism on the winding supply side to set it at the winding start position of the next section. It was hot. Furthermore, in such conventional devices, when the specifications of the bobbin, particularly the section pitch and winding width, change, it is necessary to change the amount of movement of the mechanism for moving the bobbin to the next section, the cam for traverse scanning, etc.

The object of the present invention is to provide a section winding device which solves the above-mentioned problems by providing a traverse motor independent of a spindle motor, and making it possible to control the position, speed, etc. of the motor according to the input specifications of the coil bobbin. Our goal is to provide the following.

In order to achieve the above object, a section winding device according to the present invention is a winding machine that performs section winding by driving and controlling a spindle motor and a traverse motor, and is capable of controlling the number of windings, winding width, section pitch, skip amount, and number of sections. The setting section to be set and the winding sequence control section that generates signals to control the winding, section counting, wire transfer position positioning, wire transfer operation, and return to the winding start position, and the winding sequence control section that generates signals to control the winding, section counting, wire transfer position positioning, wire transfer operation, and return to the winding start position. A set value selection calculation section that selects and calculates set values to generate speed and position signals related to traverse, and a spindle motor drive section that drives the spindle motor based on signals from the winding sequence control section. A winding number counter for counting, a winding comparator for comparing the number of windings set in the setting unit and the output of the winding number counter and outputting a signal to the winding sequence control unit when they match, and driving the traverse motor. A traverse motor drive unit, a traverse current position measurement unit that measures the current position of the traverse motor from the drive amount of the traverse motor drive unit, and a traverse current position measurement unit that compares the output of the traverse current position measurement unit and the output of the set value selection calculation unit to perform traverse. It includes a traverse position comparison section that outputs a motor drive signal to the traverse motor drive section and a signal regarding the traverse position to the winding sequence control section, and causes the traverse motor to skip the winding to the next section every time one winding section is completed. It is configured to automatically wind all sections by returning the section to the winding start position and winding.

According to the above configuration, the object of the present invention can be completely achieved.

The section winding device according to the present invention will be explained in detail below with reference to the drawings. The setting section 1 includes a winding number setting device 1n, which is a device for setting the specifications of the section-wound coil and setting the number of turns n of each section, a winding width setting device 1a, a section pitch (see Figure 2) setting device 1b, and a wire transfer. a skip amount setter 1c for setting the overstroke and skip amount for and a section number setter 1 for setting the number of sections.
d is provided. These settings are made with a digital switch. The winding sequence control unit 7 includes a winding control unit that generates winding start and stop signals for each section, and a winding control unit that checks the position of the section in the set number d of sections and sends a signal indicating the end of all sections. a section check section that generates the wire transfer, a wire transfer position positioning section that positions the wire transfer position every time a unit section winding is completed, a wire transfer operation signal generation section that generates a line transfer operation command to rotate a spindle motor 9, which will be described later, during wire transfer; A winding start position return section is provided for returning the winding supply end to the winding start position after the wire transfer is completed. The spindle motor drive section 8 is connected with signals from the winding control signal generating section of the winding sequence control section 7 and the wire transfer operation signal, and controls the rotation of the spindle motor 9. The number of rotations of the spindle motor, that is, the number of windings, is detected by a detector 10 and counted by a winding counter 11.
The winding number comparator 12 compares the count number of the winding counter 11 with the output of the winding number setter 1n previously set in the setting section 1, and outputs a signal every time a prescribed number of windings is reached for each section in the winding sequence. Send to control section. Set value selection calculation section 2
is supplied with data regarding the winding width a, section pitch b, and skip amount c from the setting section 1. In addition, data in the setting section is selected based on signals for winding control, wire transfer position positioning, winding start position return (overstroke correction) from the sequence control section 7, and a speed signal for driving the traverse motor, which will be described later. outputs a signal related to the position. A pulse motor is used as the traverse motor 6 to define the exact traverse position. The traverse motor drive unit 5 is a circuit that supplies drive pulses to the traverse motor.
The current traverse position measurement section constantly sends out an output indicating the current traverse position based on the output of the traverse motor drive section 5. Traverse position comparison section 3
is connected to a signal indicating the current traverse position and a signal from the set value selection calculation section 2, and by comparing these, an output for driving the traverse motor is sent to the traverse motor drive section 5. . It also sends information regarding the traverse position to the winding sequence control section.

Next, the operation of the apparatus will be explained with reference to the flowchart shown in FIG. First, the number of windings n, the winding width a, the section pitch b, the skip amount c, and the number of sections d are set in the setting section, and when winding is started, both the traverse motor 6 and the spindle motor 9 start rotating and the set winding width is set. The traverse motor 6 is rotated in forward and reverse directions so that winding is performed by a. The number of turns is counted by a counter 11,
The winding of the width a is continued until the number of turns reaches the number n set in the setting section 1a, that is, until the winding of the first section (1) is completed.

When the comparator 12 detects that the output of the counter 11 has reached the set number 1n of the setting section 1, the output becomes 1.
A signal indicating completion of winding of the two sections is sent to the winding sequence control section 7. The winding sequence control section 7 receives this signal and performs (a)
Generates a winding control signal to stop each motor. (b) Check whether winding of all sections has been completed by comparing with the section number setting value of the setting section. (c) If all sections are not completed, a wire transfer positioning signal, a wire transfer operation signal, and a winding start position return signal are sequentially transmitted. The set value selection calculation section 2 receives the line transfer positioning signal and calculates the section pitch b and the skip amount c.
The traverse motor 6 is driven by the traverse motor drive unit 5 by outputting a signal for positioning at a position where When the traverse position comparison section detects that the current traverse position has reached the position specified by the signal by comparing the output of the current traverse position measurement section 4 and the output of the set value selection calculation section, the traverse motor 6 is stopped. , the spindle motor 9 is rotated and once stopped by the winding transfer operation signal. This causes the winding to pass over the threshold between sections (usually with a notch for passing the wire) to the next section. Next, the traverse motor 6 is positioned at the setting 6 position (the winding start position of the next section) in response to a signal for returning to the winding start position.

When the positioning is completed, the process returns to the top of the flowchart, and winding is performed at the winding width setting a described above. When the winding of the next section is completed according to the flow, it is checked whether all sections are completed. If the winding is not completed, the winding is carried out again according to the procedure for moving on to the next section, and the winding is continued until the winding of all the sections is completed.

Since the apparatus according to the present invention is configured as described above, even if the specifications of the bobbin to be wound change, the section winding can be completed simply by changing the setting input.
