While developing a machine to cut corrugated, testing by Hipsher Tool & Die, a custom fabricator in Wabash, Indiana, revealed that the finished sheet length was inconsistent. The encoder providing length data to the cutting mechanism sometimes missed counts, which resulted in finished length variations that were out-of-spec. The machine’s existing encoder and wheel system worked perfectly with other applications, but this particular material presented a challenge.
Further investigation revealed the cause. Seams in the corrugated passing under the encoder wheel would cause it to jump and lose contact with the surface. The right encoder would need to be heavy enough to provide increased down-pressure to maintain contact with the corrugated being fed through, yet constructed with a material that would not damage the corrugated it touched. The new encoder also needed to match the old encoder’s CPR and counts per inch.
The encoder chosen had to meet the following requirements:
- Quadrature output
- Reliability
- 高分辨率
- Durability
- Sealed bearings
- Ultra heavy-duty housing
- 不会损坏材料的轮子。
THE SOLUTION
Hipeher工具和模具联系了C＆E先进技术，俄亥俄州编码器产品经销商（展位SL-6440）。在与编码器产品咨询后，C＆E的销售工程师Jeff Ligon建议型号TR3重型Tru-Trac™编码器，一个紧凑，易于使用的单元，将编码器与弹簧加载的重型测量轮组件集成。

模型TR3的主要特征包括：
- Integrated heavy-duty, all-metal encoder and measuring wheel in one unit.
- Spring-loaded torsion arm for quick wheel pressure adjustments.
- 轻松安装在垂直，水平或颠倒的方向上。
- 在高达3,000英尺/分钟的速度下可靠地运行。
- 以单轮或双轮格式提供。
- Three-year warranty.
Available in a single- or optional dual-wheel format, the Model TR3 Heavy Duty Tru-Trac encoder is a versatile tool for tracking velocity, position or distance. Its spring-loaded torsion arm provides a simple-to-adjust torsion load, allowing the unit to be mounted in any orientation, even upside-down.

The heavier housing and stiff internal spring provided down-pressure that is more than adequate to offset the “jolt” caused by the corrugated seams passing beneath the wheel. To avoid any damage to the corrugated, 12-in. dual-urethane wheels were specified.
Thee encoders also were configured with a line drive output and CPR resolution that matched the previous encoder counts per inch.
安装型号TR3并完成测试后，Hipeher的客户报告说，切割长度是现场和生产。
Starting as a one-man tool and die shop in 1946, Hipsher Tool & Die has expanded beyond tools, dies, jigs and molds to the design and fabrication of custom machinery. Customers range from walk-ins with small requests, to companies needing larger manufacturing systems.
