Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to article conveyance equipment that drives a conveyance vehicle body using a linear motor.

[Conventional technology]

The transportation vehicle body is movably guided using cylindrical guide rails and driven using a linear motor.

Conventionally, as shown in Fig. 5, the vehicle body (^) is moved along the inner surface of the guide rail (B), but in this case, the large diameter guide rail (B) is Not only does this have the disadvantage of causing major damage to the entire equipment, but it also has the disadvantage that dust tends to accumulate inside the guide rail. However, (11) in the figure is the secondary conductor on the vehicle body side, (1
2) is the primary conductor on the guide rail side.

For this reason, the applicant has developed a vehicle body (A) as shown in FIG.
The linear motor primary coil (13) is provided on the side of the guide rail (B), and the linear motor secondary conductor (14) is provided on the side of the secondary coil. We thought of a way to have it on the vehicle body in a protruding state.

[Problem that the invention seeks to solve]

In the case of the above means, although the guide rail can be made smaller,
The primary coil for a linear motor must be supported separately from the guide rail, resulting in a complicated structure and troublesome assembly.Furthermore, the primary coil for a linear motor protrudes from the side of the guide rail. Therefore, the equipment had to be sufficiently miniaturized, and further improvements were desired.

The present invention has been made in view of the above circumstances, and its purpose is to take advantage of the advantages of fitting the vehicle body onto the guide rail, and to simplify and downsize the equipment. The main point is to provide goods transport equipment that can transport goods.

[Means to solve the problem]

The characteristic configuration of the article conveyance equipment according to the present invention is that a conveyor body is provided with a cylindrical indoor rail on which the conveyor body is movably fitted, and
The primary coil for the linear motor is provided within the guide rail, and the secondary conductor for the linear motor is provided on the vehicle body side, and its functions and effects are as follows.

[Function] In other words, while the vehicle body is movably guided by being fitted onto the guide rail, it is positioned within the guide rail, or by the magnetic action between the primary coil for the near motor and the secondary w body for the near motor on the vehicle body side. , it is designed to drive the vehicle body,
Since the linear motor primary coil is located within the guide rail, the secondary coil does not protrude outward, and moreover, the secondary coil can be supported by the guide rail itself.

[Effects of the Invention] Therefore, it is possible to take advantage of the advantage of moving the vehicle body by fitting it onto the guide rail, and at the same time, to simplify the structure and improve assembly workability, and to downsize the equipment. This makes it possible to satisfy all the objectives at once, and as a result, we have obtained an article conveying equipment that has great practical advantages and is excellent both in terms of production and use.

〔Example〕

As shown in Fig. 4, a cylindrical guide rail (B) into which the transport vehicle body (A) fits is provided in a state supported by a hanging frame (1), and an article mounting frame (2) is provided. , transport vehicle body (
A) is provided in a suspended state, so that articles can be transported while the transport vehicle body (A) is driven by a linear motor as described later.

As shown in FIGS. 1 and 2, the conveyance vehicle body (A) is constructed by mounting four wheels (4) arranged in the circumferential direction at each end of an aluminum main body (3). At the same time, among the wheels (4) located in the same phase in the circumferential direction, an annular groove (U ) is formed.

The main body (3) forms an eddy current and is also used as a secondary 4 body for a near motor, and inside it is made of iron ÷ anti-iron (6) for efficiently absorbing magnetic flux. It is a provision.

The guide rail (B) includes primary coils (7) for a linear motor located at appropriate intervals in the direction of movement of the vehicle body.
and cylindrical pipes (8) are connected alternately. In other words, the linear motor primary coil (7) is connected to the guide rail (
The guide rail (B) is constructed by using the component parts of B) as well. However, in the -order coil (7),
A stainless steel cylindrical body (9) is fitted onto the outside.

More specifically, a coil (CI) in which a plurality of iron cores (stators) (7a) are connected with a spacer (7b) interposed therebetween, and a three-phase alternating current is energized therein;
Cz) and (ci) are wound to form the primary coil (7), a join l-
(10) are integrally connected to both ends of the secondary coil (7).

〔Betsuji completely defeated〕

The guide rail (B) may have a cylindrical shape or a rectangular tube shape. In addition, various modifications can be made, such as making the primary coil (7) also serve as a guide rail component, and storing the primary coil (7) in a pipe with a coil exposure hole.
The point is to position the primary coil (7) within the guide rail (B).
).

In the embodiment, a case where the article placement frame (2) is connected to the transport vehicle body (^) in a suspended state is illustrated, but the article placement frame (2)
) on the top of the transportation vehicle body (A), or
Alternatively, the transportation form can be changed in various ways, such as by equipping the article placement frame (2) with a vehicle that fits onto the guide rail (B) and having the article placement frame (2) pulled by the conveyance vehicle body (A). .
