Description

[Detailed description of the invention] (Industrial field of application) The present invention is designed to support the winding jig in the automatically continuous coil bobbin winding process, from one processing location to the next. The present invention relates to a moving jig holder for wire winding processing that is sequentially moved to processing locations.

(Prior art) Conventionally, in this type of winding process, separate devices for each process are arranged in a straight line, and the coil bobbin is transported on a belt conveyor or the like before the device that performs the first process. When it was discovered, the worker
Alternatively, a robot supplies a bobbin to a device, and when one process is completed, the bobbin is removed from the device, and the bobbin is supplied to the device for the next process.

The supply and discharge of bobbins to and from each of these devices is performed by a worker or a robot for each process.

(Problems to be Solved by the Invention) In recent years, not only the winding work but also the winding finishing work has been automated, and the feeding and discharging of the coil bobbin in each device in charge of each of these processes is increasingly being performed by robots.

For example, the winding finishing devices each include an automatic taping device, an automatic soldering device, an automatic sorting device, etc., arranged in a straight line in front of a bobbin conveying device such as a belt conveyor.

Therefore, the production line becomes long and occupies a large space.

Furthermore, since the bobbin supply position in the first process is far from the bobbin discharge position in the final process, there are problems such as the need for a long-distance bobbin transport device in order to move the bobbin to the next stage.

Furthermore, it is desirable that the soldering-related process be located as far away from the operator as possible. However, such an arrangement is often difficult.

Therefore, by performing each winding finishing process while the bobbin is inserted into a winding jig that moves endlessly and intermittently along a mouth-shaped course, each winding is finished around the circulating coil bobbin group. The above-mentioned problems can be solved by arranging a device for this purpose. However, there is a problem in that no moving jig holder suitable for supporting and moving the jig has been found.

The purpose of this invention is to solve such problems and to
The book is moved by a drive device on opposing guide rails, and when it reaches one end of one guide rail, a chuck is attached to both ends and the book is moved to one end of the other guide rail using a left-hand swing arm, and then transferred again. It is possible to move along an infinite course by being driven on a guide rail, and when it reaches one end of the guide rail, it is returned to the other end of the original guide rail by a rotating arm. An object of the present invention is to provide a moving jig holder for wire winding processing.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the movable jig holder for wire winding according to the present invention is fitted into guide rails of the same shape and dimensions at symmetrical positions above and below. Grooves 31 and 31 that fit together, and a hole 32 and a groove 33 for connecting the wire winding jig 2 on the front surface.
The structure has a bar-like protrusion 34 and a band-like protrusion 35 whose central axis is the same as the center axis of the hole 32 on the rear surface.

Each work after work 2 is performed only for the work for which the previous work has been completed. When this device is operated continuously in this way, from the state shown in a to the b, c, d, e, etc.
In each cycle, the coil bobbin after finishing winding is discharged from the device to the outside after passing through the state shown in FIG.

In this way, movement of the coil bobbin suitable for automated continuous work becomes possible only by using the moving jig holder of this embodiment.

(Effects of the invention) As explained above, the present invention has a structure in which grooves that can fit into the guide rail are provided at relative positions on both the upper and lower surfaces, and the groove can be connected to a jig and can be lockably fitted to the chuck unit. The system is driven by a drive device to move on two opposing guide rails, and when it comes to one end of one guide rail, it is moved to one end of the other guide rail by the swing arm, and then moves on top of that guide rail. When it is driven and moves and reaches one end of its guide rail,
The pivot arm allows it to be returned to one end of the original guide rail. That is, according to the present invention, it is possible to provide a jig holder that is movable along an infinite course.

Further, by using the movable jig holder of the present invention, a series of operations can be automatically and continuously carried out using devices arranged in small groups in a narrow space.
