Problems solved by technology

The current approach is expensive and requires lengthy pauses in operations
If a track unit inevitably needs to be replaced immediately due to a sudden defect, the track unit cannot be replaced in time
Consequently, the linear position detection system has to be shut down, usually for several days at a time, and the costs incurred due to the shutdown of the linear position detection system are very high

Embodiment Construction

[0035] figure 1 A schematic diagram of a rail 10 representing a linear position detection system. The track 10 comprises several track cells 12', 12", 12"', shown as three track cells.

[0036] The length of a track cell is usually limited by considerations related to the manufacturing process. As the length of the track cell increases, its manufacturing cost increases significantly. Therefore, usually the guide rail comprises several track cells arranged in a straight line relative to each other.

[0037] For installation purposes, each track cell 12', 12", 12"' is provided with several bores 14 for the insertion of bolts (not shown) which, when tightened, have threads aligned with those located in the track cell. 12', 12", 12"' under the respective receiving threaded connections of the mounting plate (not shown).

[0038] Guide rail 10 assembled in this manner serves to guide a carriage (not shown). Said way is that the carriages are guided by at least one rolling beari...

Abstract

The invention relates to a linear position measurement system for determining the position of a carriage relative to a guide rail (10) linearly formed by a plurality of track units (12', 12", 12"'), the carriage Guided by guide rails, the linear position measurement system has a plurality of measuring scales (16, 18) and at least one scanner, the scales (16, 18) respectively along the track monomers (12', 12", 12"') set and support respective position markers (20, 22); said scanners are fixed on the carriage and are designed to scan the position markers (20, 22), making it possible to determine the respective position of the carriage relative to the respective track cell of the guiding carriage. Position, in all track monomers (12', 12", 12"'), the position markers (20, 22) are identically arranged on the respective plurality of scales (16, 18). The separate coded cells (24', 24", 24"') placed on the track cells (12', 12", 12"') can be scanned by the scanner, so that the individual segment information can be passed through the guide car The respective orbital monomers are collected.

Description

technical field [0001] The invention relates to a linear position measurement system. Background technique [0002] The system described above for determining the position of the car relative to the guide rails may be used with guidance systems such as linear guides. The linear guide includes a first body and a second body, the second body is guided by the first body and moves relative to the first body, and can determine the position of the second body relative to the first body. For this purpose, the scale of the respective device for determining the position may be fixed in position relative to the first body and the respective scanner may be fixed in position relative to the second body. [0003] For example, in the prior art, a linear position measurement system that can be used to determine an absolute position includes a measuring scale marked with measuring points and a scanner that can move relative to the measuring scale for Scan the respective measuring point. ...
