Abstract
In a linear conveying device for conveying articles with a linear motor, of a plurality of shuttles, at least two are combined together to form a first operating group. In the first operating group, one of the shuttles in it is taken as a first master shuttle, and any other is taken as a first slave shuttle. The first master shuttle is controlled based on its position on the guide portion. The first slave shuttle is controlled based on its relative position from the first master shuttle.
Claims7
A linear conveying device for conveying articles with a linear motor, comprising:
- a guide portion on which a stator of the linear motor is arranged;
- a plurality of shuttles attached to the guide portion, the shuttles each moving along the guide portion while holding an article, the shuttles each having a mover of the linear motor arranged thereon;
- and
- a controller for controlling operation of the plurality of shuttles,
- wherein
- the plurality of shuttles, at least two shuttles are combined together to form a first operating group,
- in the first operating group, one of the shuttles therein is taken as a first master shuttle and any other is taken as a first slave shuttle,
- the first master shuttle is controlled based on a position thereof on the guide portion, and
- the first slave shuttle is controlled based on a relative position thereof from the first master shuttle.
A method of controlling a linear conveying device for conveying articles with a linear motor, the method comprising:
- forming a first operating group by combining together at least two of a plurality of shuttles that are attached to a guide portion having a stator of the linear motor arranged thereon, the shuttles each moving along the guide portion while holding an article, the shuttles each having a mover of the linear motor arranged thereon,
- taking, in the first operating group, one of the shuttles included therein as a first master shuttle and any other as a first slave shuttle,
- controlling the first master shuttle based on a position thereof on the guide portion, and
- controlling the first slave shuttle based on a relative position thereof from the first master shuttle.
