Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a winding device for a bobbin with terminal pins.

``Prior Art'' Conventionally, when winding a coil around a bobbin equipped with a terminal pin, as shown in FIG. 4, the nozzle 5 is rotated around the wire rod 1, thereby attaching the tip of the wire rod 1, which will become the starting end of the coil, to the winding start terminal pin 4, and then
When the bobbin 3 is rotated while the nozzle 5 is fed along the body of the bobbin 3, the wire 1 is fed out from the nozzle 5 and wound around the body of the bobbin 3 by a predetermined number of turns. Thereafter, in the same manner as above, the nozzle 5 is moved around the winding end terminal pin 6 of the bobbin 3 a predetermined number of times.
When the winding end terminal pin 6 is rotated, the wire rod 1 is
is attached. The crossover wire of the wire rod 1 attached to the winding start terminal pin 4 and the winding end terminal pin 6 is cut with a cutter 7 or the like.

"Problem to be Solved by the Invention" However, in the above-mentioned conventional winding device, when the wire 1 is attached to the winding start terminal pin 4 of the bobbin 3, as shown in FIG.
The wire rod 1 crosses from the tip to the body of the bobbin 3, and the wire rod in this part floats up with a certain gap between it and the terminal pin 4 for winding start and the wall of the bobbin 3, so that the next step is difficult. In order to apply solder to the winding start terminal pin 4 to which the wire rod 1 is attached,
When the winding start terminal pin 4 is immersed in the solder bath,
The solder rises along the wire rod 1 that runs from the tip of the winding start terminal pin 4 toward the body of the bobbin 3, and the solder also inadvertently adheres to the coil wound on the body of the bobbin 3. There's a problem. Furthermore, a wire rod 1 is passed from the tip of the winding start terminal pin 4 to the body of the bobbin 3.
As mentioned above, since it is raised from the bobbin 3, there is a problem that an unexpected load is applied and it is easy to cut. In order to prevent the wire 1 that extends from the tip of the terminal pin 4 for starting winding to the body of the bobbin 3 from floating up from the bobbin 3, the wire 1 is folded back and stacked from the tip of the terminal pin 4 for starting winding toward the base end. Even when the wire is lashed, the folded portion of the wire 1 crosses at the tip of the terminal pin 4 for winding start, so this portion bulges out from the other rabbeted portions. As a result, when the terminal pin 4 for starting winding is immersed in the solder bath in the solder filling process, molten solder is applied to the beginning of winding due to the bulge of the barbed wire 1 at the tip of the terminal pin 4 for starting winding. There is a problem in that the solder is prevented from reaching the barbed wire 1 on the base end side of the terminal pin 4, resulting in insufficient solder application.

Also, when attaching the wire 1 to the winding start terminal pin 4 and the winding end terminal pin 6, as shown in FIG. 5, especially when winding a coil such as a transformer,
When a wire rod 1 having a large diameter or a hard wire rod is used, a problem arises in that even if a large load is applied to the winding start terminal pin 4 and the winding end terminal pin 6, they may bend.

Therefore, in view of the above circumstances, the present invention has been devised so that when winding a wire automatically, when attaching a wire to each terminal pin of a bobbin, the bobbin is attached from the base end of the terminal pin without having to be folded back and tied twice. The wire rod can be passed toward the body, eliminating various problems that occur in the past due to the crossover wire part lifting up from the bobbin.Also, even if the wire rod is thick or hard, it will not work properly. There is no possibility of the terminal pin being bent due to a large load being applied to it, and furthermore, the nozzle for winding end and the nozzle for winding start can be made into a set of two, and can be attached to two terminal pins at the same time. An object of the present invention is to provide a bobbin winding device with a terminal pin that can simultaneously wind two wire rods around a bobbin body.

"Means and operations for solving the problem" In order to achieve the above object, the present invention has a set of two winding end nozzles and two winding start nozzles, and the winding end nozzle and the winding start nozzle are arranged in a set of two. The starting nozzle has an insertion hole for inserting the wire from the base end to the tip, and a receiving hole of a predetermined depth into which the terminal pin of the bobbin fits into the tip. Match the ends of the starting nozzle and insert the wire from the base end of the winding end nozzle into the insertion holes of the winding end nozzle and the winding start nozzle, and insert the wire from the base end of the winding start nozzle. After pulling it out, pull the winding start nozzle from the winding end nozzle while keeping the wire passed through each insertion hole, and then insert the winding start nozzle's receiving hole into the winding start terminal of the bobbin. After the wire is inserted into the pin and the winding nozzle is rotated around the winding start terminal pin to attach the wire to the winding start terminal pin of the bobbin, the wire rod and the bobbin are started to be wound from the winding start nozzle. The terminal pin is pulled out, and the bobbin is further rotated to wind the wire fed out from the end-of-winding nozzle around the body of the bobbin for a predetermined number of turns. After the wire is inserted into the pin, the end-of-winding nozzle is rotated around the end-of-winding terminal pin to attach the wire to the end-of-winding terminal pin.

Embodiment An embodiment of the winding device for a bobbin with a terminal pin according to the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, 11 is a nozzle drive base. The nozzle drive base 11 has the same configuration as that on which the nozzle of a conventional automatic winding machine is mounted, and as shown in FIG. It is movable in the vertical direction by the vertical drive mechanism 13, and further movable in the front and rear direction by the front and back drive mechanism 14.

The wire feed nozzle 36 has feed rollers 38 and 39 facing a nozzle hole 37 through which the wire is inserted.
The feed roller 38 is driven by a motor 40,
This drive causes the feed roller 39 to follow and rotate, thereby feeding out the wire from the wire feed nozzle 36. The rotation shaft of the feed roller 39 is elastically biased by a spring 41 in a direction in which the wire is held between the feed roller 39 and the feed roller 38 . Further, the rotation shaft of the feed roller 39 is pressed by a plunger solenoid 42 against the elastic bias of the spring 41, so that the wire can be released from being held between the feed roller 38 and the feed roller 38. The wire feed nozzle 36 and feed rollers 38, 39
is adapted to be mounted on a movable base 43. The motor 40 and plunger solenoid 42 are also mounted within the movable base 43. The movable base 43 can be moved up and down by an air cylinder 44 via a rod 45. The movable table 43 is
When moved downward by the air cylinder 44, the lower end of the wire rod feed nozzle 36 comes into contact with the base end of the winding end nozzle 26, so that the wire rod feed nozzle 36 and the insertion hole 33 coincide and communicate with each other. In this case, a concave portion is formed at the base end of the winding end nozzle 26,
It is also possible to fit the lower part of the wire rod feed nozzle 36 into the recess so that the wire rod feed nozzle 36 and the insertion hole 33 are properly aligned. The rod 45 is supported by a support member 47 on the nozzle drive base 11 via a thrust bearing so as to be vertically movable. The air cylinder 44 is attached to the nozzle drive base 11 via a fitting or the like. A guide roller 48 is disposed between the wire feed nozzle 36 and the winding end nozzle 26. The guide roller 48 is attached to the nozzle base 23 via a support member 48a. The guide roller 48 is

When the base end edge of the insertion hole 33 of the end-of-winding nozzle 26 is rounded, the guide roller 48 is unnecessary.

The nozzle drive base 11 is provided with a winding start nozzle 49 as shown in FIG. The winding start nozzle 49 has the same configuration as the winding end nozzle 26,
As shown in FIG. 4, two winding start nozzles 49a, 49b are connected to gears 54a, 54 at the upper end.
