Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a linear conveyance device, and particularly to the structure of primary coils distributed on a line.

[Conventional technology]

As shown in Fig. 3, the linear conveyance device consists of stations (1) consisting of primary coils distributed on a line (1).
2) and a moving body (hereinafter referred to as a slider) (3) as a secondary side that is conveyed on a line by the action of the magnetic field generated in the primary coil. The principle of this linear conveyance device is mechanical design, Vol. 29, 10th issue, P3.
6 to 41 (published by Nikkan Kogyo Shimbun), by changing the energization state of the primary coil constituting station (2), the direction of the traveling magnetic field is reversed and braking is performed. It is configured. In this way, the primary coil acts as an acceleration/deceleration means, and the slider (3) is accelerated and braked only by the primary coil.

(Problem to be Solved by the Invention) However, in the conventional linear conveying device, the primary coil is fixed to the line (1) at a predetermined interval. If the stationary coil (2) as the primary coil is placed in another position, peripheral devices such as motors and sensors that make up the primary coil will be installed separately for the line (1). In order to change the station (2) as necessary, peripheral equipment such as motors and sensors attached to station (2) must be relocated individually.
Major remodeling work is required.

The present invention has been made to solve these problems, and provides a linear conveyance device that can move the station (2) relatively easily.

[Means for solving problems]

In the present invention, the primary coil and the equipment attached thereto are configured as a module, and a moving mechanism is provided to move the module along a line as a basic unit.

[Effect]

According to the present invention, the module serving as the primary coil can be easily moved to a desired position via the moving mechanism.

(Example) The present invention will be described below based on FIGS. 1 and 2. FIG. 1 is a side view showing a station (2) as a primary coil, and FIG. 2 is a front view thereof.

As shown in Figure 3, the linear conveyance device is similar to the conventional one.
Stations (2), which are primary coils, are distributed at predetermined intervals on the line (1). A slider (3) as a secondary side is located on the station (2).

Therefore, when the station (2) is energized, a traveling magnetic field is generated, and the slider (3) affected by the traveling magnetic field is transported on the line (1) to another station (2) on the downstream side. The slider (3) runs inertia. If the brake is applied at the station (2), the slider (3
) will stop, but if a traveling magnetic field is obtained, it will be further accelerated and will inertially travel to the next station (2). In other words, the slider (3) is accelerated or decelerated only at the position of each station (2).

FIGS. 1 and 2 are enlarged views of the main parts of the apparatus of this embodiment. As shown in FIG. 1, the station (2) is constructed as a module (6) equipped with a linear motor (4), a sensor (5) for detecting the position of the slider (3), etc. At the center of the bottom surface of the module (6),
As shown in FIGS. 1 and 2, a pole screw (7) is longitudinally penetrated and engaged, and the pole screw (7) is disposed along the line (1).

Specifically, as is clear from FIG. 2, the line (1) has a pair of rails (
la), (la) are extended, and the rail (1, 1)
.

Wheels (3a) and (3a) of slider (3) are shown in (la).
) is straddled and transferred and runs on the rails (la) and (la). Below the slider (3) is a station (
2) is constructed and arranged as a module (6) as shown in the figure.

Therefore, when changing the station (2) to another position, the module (6) is used as a basic unit and the motor (4), sensor (
5) and other peripheral equipment can be easily moved as one unit, and furthermore, the degree of relocation work can be improved in terms of flood prevention. Therefore, the complicated relocation work of relocating peripheral devices individually as in the past is no longer necessary, and Station (2)
can be moved extremely easily.

In this embodiment, only the wheel-type slider (3) was explained, but the slider (3) employing other methods may also be used.
It is clear that this can also be applied to

Further, by installing a plurality of stations (2) on the pole neck 7), it is also possible to move only an arbitrary station.

[Effects of the Invention] As described above, according to the present invention, the station as the primary coil of the linear conveyance device is modularized, and a moving mechanism is provided to move the station integrally, so that the station can be moved extremely easily and with high efficiency. Can be changed to other positions with precision.
