1 Cavity Fully Automatic Shuttle Model TS1000

  • Excellent Price
  • Excellent Performance




Range of Linear Shuttle Machines
  • 1 to 6 cavities
  • Most widely used machine type for small to medium sized applications
  • Outputs from 1,000 to 8,400 b/h with all - electric model
  • Neck sizes from 30 to 200 mm
  • Volumes from 50 ml to 5 gallons
  • Heat set, thread orientation, and preferential heating available on some models




Benefits and lssues of Linear Shuttle Machines
  • Shuttle means that the movement through the ovens is 'go - and stop'
  • + Low capital investment
  • + Easy setup
  • Preform heat Iess than continuous motion machines; to compensate Chumpower machines allow the adjustment of blow parameters for individual cavities
  • Spacing in ovens is the same as in blow mold - this is not as efficient as more air is heated up and escapes



Chumpower Acronyms
  • CPSB: Chumpower Stretch Blow
  • T: Standard
  • Number: Number of cavities times 1,000 (except in rotary and LS machines)
  • L: Large container

LS 6000
  • This linear rnachine is different in several ways:
  • In - feed is like a rotary machine with star wheels:
  • proven concept with high reliability
  • Movement of preforms through the ovens is
  • continuous: even heat for all preforms
  • Spacing in ovens is fixed depending on model;
  • preforms are then spread to blow mold pitch: batter use
  • of ovens, energy savings
  • Servo motor clamp: fast and reliable



Design layout
  • Compact design
  • Space savings
  • Easy access
  • Easy maintenance



Infeed
  • Compact design
  • Space savings
  • Easy access
  • Easy maintenance



Heating section
  • Modular ovens with easy access
  • 50 mm preform spacing for best energy usage
  • Preform are always right side up eliminating turn over problems, chain wear etc.
  • 2 x 3 ovens layout with turnaround section for equalization of preform temperature



Oven Details
  • Chumpower lamp spacing is 17 mm {155mm on request)
  • Lamps can be moved
  • 6 to 16 lamps per oven
  • Each lamp can be turned on or off
  • Heat shield is watercooled



Pitch Changing Unit
  • Preform transport and pitch unit are both controlled by servo motors
  • Pitch unit grabs preforms, then moves them towards blow clamp and enlarges the pitch to blowing dimension



Clamp Unit
  • Toggle clamp triggered by cam
  • Cam controlled by servo motor
  • Cam rotates continuously in one direction greatly reducing vibration
  • Patented design
  • Stretch rod is servo motor controlled
  • Each cavity has its own set of blow valves allowing individual control and reducing air consumption
  • Blow nozzle seals on transfer ring - no neck deformation
  • Bottom insert movement is mechanically coupled to clamp
  • Pressure compensation reduces bottle parting line and mold wear





New: All speeds now increased from 1500 to 1700 parts/hour per cavity.
CPSB LSS 12000 now available (12 cavity) at 20,000 parts/hour. (0.61.)




Rotary Machines
  • CP offers a 10 - cavity machine at this time
  • There are 4 models:
  • CPSBR - 10 - 36: Max. neck 28 mm, oven pitch 38 mm
  • CPSBR - 10 - 50: Max neck 43 mm, oven pitch 50 mm
  • Both machines have a maximum output of 14,000 b/h
  • CPSBH - 10 - 38H; Same as above for heat - set
  • CPSBH - 10 - 50H: Same as above for heat - set
  • Heat set machine output is 10,000 b/h



Benefits of Rotary Machines
  • Every preform is exposed to the exact same amount of heat and time between heating end blowing
  • Small oven pitch allows efficient heating
  • Synchronization is mechanical and, once set, very repeatable
  • Low dead - volume of air means lower air consumption
  • In - feed end out - feed are both mechanical and not prone to failure.
  • Pressure compensation means Iess stress on mold



Chain Pitch in Ovens
  • In indexing machines pitch of mandrels in the ovens is the same as in blow mold "4"
  • Ovens are not loaded optimally
  • Large necks possible
  • In rotary and LS - 6000 machine pitch is either 38 or 50 mm
  • Energy savings due to better oven usage
  • Neck size limited by pitch: transfer ring must be 1.5 mm smaller than pitch



Compressors
  • Blow machines need 30 to 40 bar (420 to 580 psi) air pressure
  • Compressor is by far the most expensive ancillary equipment for stretch blow molding
  • PET All compressors use a Chinese supplier that came out of lngersoll - Rand as the best compromise between low cost and reliability
  • These compressors are modular. Single unite of 20 to 40 cfm are stacked together to form larger systems that can easily be expanded
