Abstract

PURPOSE:To perform taping even at the start of windings without making lead parts of the windings get out of positions and obtain a device to facilitate difficult winding works in such a manner that each lead part goes across at a right angle to the winding circumferential face of a coil by causing this device to be equipped with respective specific elements such as first and second pressing members and a tape delivery mechanism and a cutter as well. CONSTITUTION:The free end of a tape 32 coming from a tape reel 33 is allowed to abut on a coil winding circumferential face 45 through a claw part 14 at which the pointed end of its claw part runs slantwise with respect to the winding circumferential face 45 of the coil 44. Further, this device is equipped with: the first pressing member 2 which holds bindingly each wound coil; a tape delivery mechanism which delivers the tape 32 to be wound to the coil from the tape reel 33 according no the condition of its tape abutting on the coil face; the second pressing member 4 which makes the delivered tape 32 abut on the coil winding circumferential face 45; a cutter 3 which cuts the tape 32 along the pointed end of the claw part 14 of the foregoing first pressing member 2. For example, cutting of the tape 32 by means of the cutter 3 is performed by lowering an arm 21 while pressing down the tape 32 on the circumferential face 45 with the second pressing member 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an apparatus for taping the winding surfaces of inner layer windings, intermediate windings, outer layer windings, etc. of a coil.

(Prior art) The peripheral surface of a coil after winding or the inner layer winding of a coil,
It is known to wrap a protective and insulating tape (adhesive tape) around the circumferential surface of an intermediate winding, etc., and this type of taping device uses a guide part of the tape fed out from a tape reel and a free end of the tape. There is a device equipped with a clamp that grips the tape, a pressure roller that adheres the tape that has been fed out to the circumferential surface of a rotating coil, and a cutter that cuts the tape (see Japanese Patent Laid-Open No. 59-26841, etc.).

(Problem to be Solved by the Invention) By the way, depending on the number of turns of the coil, etc., the winding glue part may be formed so as to cross the circumferential surface of the winding from the middle.
In this case, in the case of an inner layer winding or an intermediate winding in which a wire is further wound on the outside, it is desirable that the lead portion crosses the circumferential surface of the winding at right angles.

In conventional devices, the lead wire at the end of the winding remains formed so as to cross at right angles, which has the disadvantage that it is easily deformed while being transported to the subsequent process.

In addition, at the beginning of winding, unless the wire is held down while forming, the tension of the wire makes it impossible to maintain a perpendicular shape, making winding virtually impossible.

The object of the present invention is to provide a depinking device that solves these problems.

Means for Solving the Problem) This invention brings the free end of the tape from the tape reel into contact with the coil winding surface through a claw portion whose tip is substantially oblique to the coil winding surface. At the same time, a first pressing member capable of holding the coil winding is connected, and in this contact state, the tape is fed out from the tape reel for the coil winding, and the tape that is fed out is brought into contact with the circumferential surface of the coil winding. The tape includes a second pressing member that causes the tape to adhere, and a cutter that cuts the tape along the tip of the claw portion of the first pressing member.

(Function) Therefore, the free end of the tape is brought into contact with the circumferential surface of the coil while the winding is held by the claw portion of the first pressing member, and then the tape that is fed out is wound and the tip is pressed. At times, the winding glue - 1 part etc. does not shift or distort,
In addition, since taping can be applied to the beginning of the winding, difficult winding work in which the lead section crosses the winding surface of the coil at right angles is also facilitated.

(Embodiment) FIGS. 1 to 4 show an embodiment of the present invention, and 1 is a main body portion equipped with a first pressing member 2, a cutter 3, a second pressing member 4, a tape cassette 5, etc. , 6 is a base portion on which an actuator 7.8 consisting of an air syringe is arranged.

The base portion 6 is attached to a drive mechanism (not shown) of a robot device or the like, and is movable in various directions such as front and back, left and right, and up and down.

The main body part 1 has a support shaft 12 erected on the base part 6 through a mounting hole 10 formed in the lower base frame 9 and a presser holder 11 .
13 and can be freely attached and detached and replaced.

The first pressing member 2 is a plate-shaped member having a claw portion 14 of a predetermined width, and is fixed to the upper part of the main body portion 1 with the claw portion 14 projecting forward (to the left) by a predetermined amount. The tip of the claw portion 14 is formed to be somewhat oblique to a predetermined side (for example, the base portion 6 side) with respect to the width direction, and the upper surface of the tip is cut out so that the tip has a predetermined thickness.

Two small guide rollers 15 are provided on the lower surface side of the claw portion 14.
．． 16 is freely rotatable through the roller frame 17, and in front of the guide rollers 15 and 16 is a U-shaped guide pin 18 extending from the roller frame 17 along the claw portion 14 to near its tip. is installed protrudingly.

The cutter 3 is inserted into the pole 1 at the tip of an arm 21 which is rotatably supported through a pin 20 in one opening formed behind the claw part 14 of the first pressing member 2.

In this case, the cutter 3 is mounted so as to move obliquely in the width direction in line with the tip of the claw 14, and so that the cutting edge protrudes downward along the tip of the claw 14 during operation.

The second pressing member 4 is made of a member having a sliding surface 22 of a predetermined size at its tip, and is housed in the arm 21 with a bolt so that the sliding surface 22 is located a predetermined distance in front of the cutter 3. It will be done.

Further, a rod 23 is inserted through the arm 21 from the side, and a pair of links 24 rotatably supported on the side surface of the main body 1 are engaged with both ends of the rod 23.

A lever 25 is integrally formed on the link 24 on the base portion 6 side, and a spring 26 for biasing the lever 25 backward is attached to the tip of the lever 25, and a push rod of the actuator 7 disposed on the base portion 6 A pin 29 that engages with the pin 27 via a push plate 28 is provided upright.

When the actuator 7 is turned on (air supply), the push rod 27 and the push plate 28 move backward, and at this time, the lever 25 and the link 2 are moved by the biasing force of the spring 26.
4. The arm 21 moves downward about the pin 20 via the rod 23 and overlaps the first pressing member 2. Further, when the actuator 7 is turned OFF (air release), the push rod 27 and the push plate 28 move forward, and therefore, at this time, the arm 21 or the pin 20 is used as a fulcrum via the lever 25, the link 24, and the rod 23. It moves upward and becomes the state shown in Figure 1.

Note that 30 is a kite of the push plate 28 of the actuator 7.

On the other hand, the tape reel 1-5 rotatably supports a tape reel 33 in which a predetermined adhesive tape 32 is wound around a diagonally cut reel 31, and is also swingable in the direction in which the tape 32 is fed out. Thus, one end of the data cassette 5 is attached via a pin 35 to a support arm 34 extending from the winding frame 9 of the main body 1.

A stopper 36 for regulating the swinging position of the tape cassette 5 and a spring 37 for preventing wobbling are provided at the tip of the support arm 34, and an actuator disposed in the pace section 6 is provided on the side surface of the tape cassette 5 on the side of the base section 6. A pin 40 that engages with the eight rods 38 through three block members is provided to form a feeding mechanism for the tape 32.

When the actuator 8 is turned on (air supply), the rod 38 and the frame member 39 move forward, and at this time, the tape cassette 5 swings backwards with the pin 35 as a fulcrum via the pin 40, and the tape cassette 5 The upper side is a predetermined distance from the main body. Moreover, the actuator 8 is OFF.
When the air is released, the rod 38 and the three block members move backward, and therefore, at this time, the table cassettes 1 to 5 return to the main body 1 side using the pin 35 as a fulcrum, resulting in the state shown in FIG.

Note that 41 is a guide for the three piece members of the actuator 8.

Furthermore, movable rollers 42 and 43 are respectively disposed at a portion of the tape force set 1-5 on the main body 1 side and at a central portion of the main body 1.

Then, the tape 32 pulled out from the tape reel 33
is guided from the lower side of the movable roller 42 to the upper side of the movable roller 43, and is further passed between the claw part 14 of the first pressing member 2, the guide rollers 15, 16, and the kite pin 18, and then the free end of the tape 32 or the claw part It is set so that it reaches the tip of 14.

Next, the operation of this device will be explained with reference to FIGS. 5 to 10. In this case, a coil in which the lead portion of the winding crosses the circumferential surface of the winding at right angles will be described as an example.

First, the device is moved by a drive mechanism (not shown), and the fifth
As shown in the figure, each roller 42, 43.
The free end of the tape 32 set on the tip of the claw portion 14 of the first pressing member 2 is attached to the spindle or the like of a winding machine (not shown) from above via the tip of the claw portion 14 of the first pressing member 2 through the [15, ]6. It is brought into contact with the winding peripheral surface 45 of the coil 44 with a predetermined pressing force.

In this case, if the hand link type winding machine is used, the coil 4
Regardless of whether the winding starts or ends in step 4, as shown in FIG. However, in the case of a nozzle type winding machine, when winding the coil 44 is finished, the lead portion 47 is left in place and the protruding end of the tape 32 is brought into contact with the winding wire 48 on the winding surface 45 using the tip of the claw portion 14. Let them come into contact with you. Also, if you have started winding the coil 44 with the nozzle type,
As shown in FIG. 10, the protruding end of the tape 32 is brought into contact with the lead part 47 which crosses the winding surface 45 by the tip of the claw part 14. In this case, it is preferable to increase the oblique angle of the tip of the claw portion 14 to increase the adhesion area of the protruding end of the tape 32 on the lead portion 47 side.

Therefore, the free end of the tape 32 is adhered from the upper side of the winding 48 or the leat part 47, and in the case of FIG. 9, it is held by the winding 48 or the tip of the claw part J4.
In this state, the leat portion 47 can be easily attached to the terminal 46 by bending the bent portion 47 along the tip of the claw portion 144.

Further, in the case of FIG. 10, since the lead portion 47 is held at the tip of the claw portion 4, the winding 48 can be bent at the tip of the claw portion 14. As a result, when the winding of the coil 44 is started, the lead portion 47 does not shift, and it is possible to easily enter the winding when the winding is finished.

Next, with the free end of the tape 32 in contact with the winding 48 or the lead part 47, the actuator 8 is turned ON, and the tape cassette 5 is attached to the pin 35 as shown in FIG.
1. In this case, the free end of the tape 32 is pressed against and in contact with the coil 44 side by the claw part 14, so that the free end of the tape 32 is rotated backward to a predetermined position using the tape cassette 5 as a pivot. The tape 32 corresponding to the winding of the coil 4/1 is unwound from the tape reel 33.

Next, set the actuator 8 to 0FFL, and set the tape cassette 5 to 0FFL.
After returning to its original position, the device is moved back a predetermined amount in the tangential direction of the winding surface 45 of the coil 44, as shown in FIG. At this time, if necessary, a predetermined amount of tape 32 can be wound around the winding surface 45 of the coil 44 by rotating the coil 44.

Then, in the state shown in FIG. 7, the actuator 7 is turned ONL,
Arm 2 via lever 25, link 24, and rod 23
1 is moved down using the pin 20 as a fulcrum. As a result, the second pressing member attached to the arm 21 replaces the first pressing member 2.
The sliding surface 22 of the pressing member 4 is connected to the coil 44 as shown in FIG.
While contacting and pressing the tape 32 on the winding surface 45,
The cutter 3 descends and cuts the tape 32 that has been fed out. Therefore, when the tape 32 is cut, the tape 32 that is in contact with the coil 44 side will not be peeled off.

After cutting the tape 32, by rotating the coil 44, the terminal end of the tape 32 is wrapped around the winding surface 45 by the second pressing member 4 without being applied, and the team pinking is completed. Note that since the tape 32 is cut by the cutter 3 along the tip of the claw portion 14 of the first pressing member 2, the next taping can be started without resetting the tape 32.

In this way, the claw portion 14 of the first pressing member 2 allows
The free end of the tape 32 is applied while holding the winding 48 and the lead part 47 of the winding /1.8, and the unwound tape 32 is further wound, so that the lead part 47 of the winding 48 is attached to the coil 44. When the winding circumferential surface 45 of the coil 44 is crossed at right angles, the winding 48 and the leat portion 47 can be taped without being shifted or distorted.Especially with a hand-link type winding machine, the winding start and the winding of the coil 44 can be taped at right angles. Finally, in a nozzle type winding machine, at the end of winding the coil 44, the winding 48 is
Since the lead portion 47 is held in place, the lead portion 47 can be easily attached to the terminal 46 by bending the lead portion 47 along the tip of the claw portion 14 at the same time as taping the winding 48 portion. In addition, in the nozzle type winding machine, the reed part 47 is held and taped by the tip of the claw part 14 at the beginning of winding the coil 44, so when the winding part 48 is folded, the taping is finished. Winding can be performed easily in the same way as starting winding of the coil 44 with a winding machine.

In the past, it was possible to neatly tape the windings, and when winding the windings on the outside, the windings could be neatly wound, and difficult winding work could be done easily.

(Effects of the Invention) As described below, according to the present invention, the free end of the tape from the tape reel is wound into a coil through the claw portion which runs substantially obliquely to the winding surface of the seaport T-coil. A first pressing member that can be brought into contact with the circumferential surface and capable of holding the coil winding; a tape feeding mechanism that feeds out a coil winding (=I amount of tape) from a tape reel in this abutting state; Since it includes a second pressing member that is brought into contact with the circumferential surface of the coil winding, and a cutter that cuts the tape along the tip of the claw portion of the first pressing member, there is no possibility that the winding wire or the lead portion of the winding will be rubbed. Taping can be easily performed without having to do anything, and when the lead portion of the winding crosses the circumferential surface of the coil at right angles, the winding work is also facilitated.
