Design Specs

Assumptions

This specification list was compiled assuming 750mL bottles traveling at 400 bottles/min with a space of one bottle diameter between each bottle. For the purposes of cycle numbers, we assume a worst case operation of 16 hours/day, 365 days/year, and a lane switching frequency of 10 bottles per lane. A full cycle requires the mechanism to transition from ‘off’ to ‘on’ and back to ‘off’, allowing 20 bottles to pass. This adds up to nearly 7 million cycles per year.

Performance Specifications

The Laning Mechanism shall:

  1. NOT cost more than $20,000 in parts, or more than $10,000 in installation.
  2. Reduce maintenance costs for the current $10,000/year.
  3. NOT damage or scuff bottles or labels.
  4. Allow for either packer lane to be utilized independently.
  5. This would require the mechanism to remain in either the ‘on’ or ‘off’ position for extended time if necessary.
  6. Accommodate for variable line speeds.
  7. Be frequency adjustable.
    • This refers to the number of bottles to pass per cycle.
  8. Follow food handling guidelines and regulations.
  9. Be actuated without interfering with bottles.
    • This means that any mechanism should be able to switch from ‘on’ to ‘off’ without a bottle being influenced in this transition. The likely way to accomplish this is to have the actuation take place in the space between bottles as they pass. Our approximation of this time is 0.064 seconds from base to base.
  10. Be able to redirect bottles moving with a kinetic energy of 0.5-1.0 Joules.
  11. Be sustainable with routine maintenance.
  12. Fit in the existing system’s footprint.
  13. NOT cause downed bottles.
  14. NOT present a safety hazard to employees during operation or maintenance.

Design Specifications

  1. The frequency adjustability shall be done by counting bottles (as opposed to a timed action).
  2. Routine maintenance shall be accomodated in the design. Special tools or parts should not be necessary to service and maintain the mechanism.
  3. Tipping must be controlled, both induced (through the mechanism’s workings) and accidental.

Ideal Cases

  1. The design is applicable in various lines with various bottle types.
  2. The design has a lifespan of 5 years (35 million cycles).
