6. OPERATION

6.1. Preform Feed

6.1.1. Loading Preforms on the Feed Turntable

The feed rail (A) conveys preforms (B) to the guides (15C and 16C).When the operator initiates the preform feed sequence, the PLC operates the cylinder(58D) to retract the preform feed barrier (33D).The preforms (B) then begin feeding to the feed tray (06C).The low preform level sensor (B13.3) controls preform feed to the feed tray.Whenever the level of preforms on the feed rail (A) drops below the low preform levelsensor (B13.3), it extends the preform feed barrier (33D) to interrupt preform feed tothe feed tray.Preform feed (B) cannot resume until the level of preforms on the feed rail (A) rises tothe level of the high preform level sensor (B13.2).Note: An incomplete preform neck sensor (B12.7) can be installed on the feed rail

(A) as an option.

6.1.2. Synchronizing Preform Loading

The preforms from the feed unit (A) mate with a notch on the feed tray (06B). Whenthe operator starts the preform (A) feed sequence, the loading synchronization sensorgives the go-ahead to start loading and synchronizes preform barrier (33C) retractionand arrival of the first notch of the feed tray (06B).

Note: A pneumatic assistance unit on the supply block (A) optimizes preformfeeding.

6.1.3. Preform Misfeeds

One side of the preform neck ring rests on the feed turntable (06) and the other on theretractable guide (01).If a preform at the tray entrance is not correctly positioned, it will bump the retractableguide (01). Sensor B23.0 detects motion of the guide and retracts it.Retraction time (4 to 5 seconds) permits ejection of several preforms.Preform feed resumes normally once the guide is back in position.Note: Any 5 consecutive misfeeds causes the machine to shut down progressively.Empty molds (no preforms) do not undergo preblowing or blowing.

6.2. Preform pick-up

6.2.1. Presentation

The preforms engage on the preform feedwheel tray (06A): the preformmovements aresynchronized with the oven pitch (the gap between the spindle shafts).

The preforms are then taken to the stabilization wheel (03B) and then to the oven feedwheel (03C) where they are loaded onto the spindles.

If there is any stress on the lower shaft (31D) of the oven feed wheel (03C), the torquelimiter (41D) is set off and the machine stops.

6.2.2. Preform Loading

The loading cam (06A) is located in the top part of the oven turntable.

The fork (03A) keeps the spindle shaft aligned with the pinion.

The fork roller (13A) moves across the cam (06A). At the end of the loading cam, thespring (11A) expands. The fork drops pulling the spindle shaft with it.

The spindle tip on the end of the shaft, inserts in the preform neck. The preform is nowsecured on the spindle and is transferred to the oven.

If there is excessive resistance to preform loading, the fork roller (13A) hits the camfollower (07A).

The sensor (B13.1) detects slight motion of the cam follower (07A). It notifies the PLC,which raises the ejection cams (01B and 09B).

The ejection cams then eject the incorrectly loaded preforms.

6.2.3. Ejecting Incorrectly Loaded Preforms

If a preform is incorrectly loaded, the spindle tip will not be inserted completely in thepreform (A) neck.

As a result, the roller (13B) will not drop completely and will knock on the camfollower (07B).

Cam follower motion is detected by the preform loading interlock sensor (B13.1). Thesensor notifies the PLC, which operates the cylinder (03C) to raise the ejection cams(01C and 09C).

The roller (16B) travels over one of the ejection cams and raises the fork (03B).

The fork (03B) pulls the pinion (E) up. The spindle tip retracts into the ejector (D). Thepreform is released and drops into the ejection chute. The following preform is alsoejected when the roller (16B) travels over the other ejection cam.

A7 bar compressed air nozzle (14C) blowsboth preforms toward the ejection chute. Themachine continues the normal operating cycle.

If 5 consecutive preforms are incorrectly loaded, the machine shuts down progressivelyonce all the preforms have exited the oven.

6.3. Preform Heating

6.3.1. Description

The preforms are heated by 16, 18 or 20 infrared heating modules, depending on themodel of machine.Each infrared oven heatingmodule can hold up to 9 superimposed infrared lamps (zones1 to 9). The lamp bases are cooled by air.Heating is achieved by direct exposure of the preforms to the rack-mounted infraredlamps.The racks can be moved to move the lamps nearer or farther from the preforms.The lamp power, either 2,500 or 3,000 W, can be changed for different types ofproduction.An infrared camera at the oven exit reads the preform temperature and reports it to theprogrammable logic controller. This permits control of oven temperature to within±1˚C.Note: The 3,000 W lamps are installed in zone 1 only.The oven is divided into two parts:

- Penetration oven.

6.3.2. Heating Preforms Neckdown

The preforms in the in-line oven are heated with the neck down to promote heating ofthe preform bodies, since heat from the lamps rises. The upended position also keepsthe preform necks from deforming when the preforms are transferred to the molds.The preform necks are shielded from direct exposure to the lamps by water-cooled heatbarriers to avoid softening and possible deformation.The preforms are rotated throughout the heating phase to distribute heat uniformlyaround the preforms.The spindles are rotated by the top cog (06B) and the bottom cog (07B) on the spindlemeshing on the two single chains (03C).When the hot preforms exit the oven, a downending ramp (04A) turns the preforms 180°so that the neck is up.

6.7.2.1. Square GUPM mold support unit locking

The mold support unit is closed.

The cam follower (34A) moves along the locking cam (02B).

The profile of the cam (02B) causes the follower to rise taking with it the shaft(16B) / locking (17A, 18A) assembly.

The locking pins (17A, 18A) slide into the rings on the left support block(02A).

The mold support unit is now locked.

Note: The brake disc (29A) presses on the shaft (16A), and holds the shaft(16A) / locking (17A, 18A) assembly until the unit reaches theunlocking cam. If there is a malfunction on locking, the follower(34A) will be pressed on the locking cam (02B). The cam will moveslightly on the pivot pin (04B). The detector (B12.3) (mold notlocked) indicates the movement to the plc. The plc preventspreblowing and blowing in the incorrectly locked mold support unit.
