How to specify a fixed digit number in antlr grammar?

I want to parse a line which contains fields of fixed number of characters. Each field is a number.

0034|9056|4567|0987|-2340| +345|1000

The above line is a sample line. | indicates field boundaries.

The fields can include blank characters +/-
