Problems solved by technology

However, since a plurality of brackets need to have different characteristics, the production becomes complicated, leading to an increase in cost
Also, depending on the method of adding features, it is difficult to add different features when the number of brackets is large
That is, in practice, the number of bays is limited

Embodiment approach 1

[0028] A procedure for realizing the linear motor conveyance system according to Embodiment 1 will be described.

[0029] In a linear motor conveying system, in order to control the movement of multiple carriages independently, it should be possible to distinguish each carriage, but sometimes it is required to be able to identify multiple carriages separately. For example, when mutually different jigs are attached to a plurality of brackets, it is necessary to identify each of these plurality of brackets.

[0030] On the other hand, linear motor conveying systems stop and start periodically or irregularly. For example, depending on the factory, for the sake of safety, the operation is stopped after get off work, and the system is activated after work. Also, for example, when a linear motor conveying system is used separately for multiple processing lines, the number of processing lines that need to be operated may increase or decrease as the number of product orders increases...

Deformed example 1-1

[0061] In Embodiment 1, a so-called moving magnet type linear motor conveyance system in which a plurality of electromagnets 24 are arranged on the stator 20 and magnets are arranged on the rotor 22 has been described, but the present invention is not limited thereto. The technical idea of ​​the embodiment and the above-mentioned modifications can also be applied to a so-called movable coil type linear motor conveyance system in which a plurality of magnets are arranged on the stator 20 and electromagnets are arranged on the rotor 22 .

[0062] Two, the second aspect of the present invention

[0063] Hereinafter, a second aspect of the present invention will be described with reference to the drawings.

Embodiment approach 2

[0065] The inventors of the present invention have obtained the following knowledge as a result of studying a linear motor conveyance system that moves a plurality of carriages along a predetermined path using a linear motor.

[0066] As long as the number of brackets does not increase or decrease or the arrangement order of the brackets on the path does not change, it is only necessary to detect a certain specific bracket among the multiple brackets and assign multiple The unique identification information means that the same and unique identification information can be assigned to a plurality of trays each time. That is, each bracket 10 can be identified substantially. In this case, it is possible to use most of the plurality of trays (for example, all of the trays except for a specific tray) in common use, and thus cost can be reduced.

[0067] Therefore, in the present embodiment, when the linear motor conveyance system is activated, a specific bracket is detected as an i...

Abstract

The present invention provides a linear motor delivery system for improving the value of a commodity. The linear motor delivery system (100) of the present invention is provided with: a bracket (10_1-10_5); a linear motor (12), a drive bracket (10_1-10_5); control means (14) for controlling the linear motor (12) to move the carriage (10_1 -10_5) along the path (P).; a wireless tag (16_1-16_5) mounted on the bracket (10_1 -10_5), and wherein information about the carrier (10_1-10_5) is stored; and a plurality of wireless tag readers (18) configured along the path (P) and read information stored in the wireless tag (16_1 -16_5).

Description

technical field [0001] The invention relates to a linear motor conveying system and its application method. Background technique [0002] Conventionally, a linear motor conveyance system is known as a conveyance system for conveying articles, which uses a linear motor as a drive source to move a plurality of carriages, and conveys articles using the carriages. The linear motor conveyance system includes: a carriage driven by the linear motor; and a control device for controlling the linear motor to move the carriage along a predetermined path, and conveying the articles held by the carriage by driving the carriage along the path. [0003] In contrast to conventional conveyor belts that convey objects (ie, articles) in the same direction at a constant speed, linear motor conveyance systems are generally capable of individually controlling the movement of multiple carriages that hold the articles. In addition, it is also possible to perform control such as stopping the carria...
