A Air Dump Valve – releases air pressure when any interlocked guard is opened, or an E-Stop is activated.
Automatic Sleeve Roll Changeover – fully automatic system for the feeding of a new roll without operator intervention at the time of splicing. New roll is prepped by the operator while the machine is running and machine automatically runs the new roll at the proper time. This is in contrast to a splicing or accumulation system which requires operator involvement at the moment of splicing.
B Band Locating Rollers – also known as Sleeve Locating Rollers, these are rubber disks mounted on variable speed motors which insure the label is fully seated down to the conveyor.
Bar Code Verification – sensor which reads and confirms each bar code on the flat label web prior to application and can trigger an ejection unit or pause the machine.
C Cabinet Air Conditioner – as an upgrade to those models which require a heat exchanger. Unit maintains a fixed temperature in the electrical cabinet.
Cabinet Cooler – also known as Closed Loop Heat Exchanger, used with machines containing servos to maintain cabinet temperatures.
Casters & Leveling Pads – available on some machine models to move machines from line to line.
Cluster Lubrication – connects flexible lines from bearings to a manifold on the exterior of the machine frame.
Complete Set of Tooling – all the size-specific components required to run a given container and neckband or label.
Conveyors – conveyor belts, either plastic or stainless steel chain, with either AC or DC drives, used to convey containers into, out of, or through a PDC machine. Conveyor drive may be in the PDC electrical enclosure and the speed may be controlled on the push button station or HMI/Operator Touch screen.
Crating for Shipment – complete enclosure of machine in a sturdy wooden crate; typically required for export by truck or ship. In the standard preparation for shipment the machine is lagged onto a skid and wrapped.
D Digital Dials for Quick Changeover – numerical dial readouts that note position; used to provide guidance for changeover.
Downstream Photo Eye – monitors product flow after machine and detects back up on conveyor downstream of the machine, such as from a paused case packer. When the photocell is blocked, the PDC machine is paused. Once the jam is cleared the PDC machine will sound a tone to alert operators and the machine will automatically restart.
Drive/Motor – DC – standard motor and controller type for most machine models.
Drives AC Upgrade – conversion from DC drives/motors to AC. Benefits: AC drives are brushless and require less maintenance and also control speed more precisely (CHECK) especially in higher speed applications. Dual Speed Control – photocell and circuitry which monitors upstream accumulation area or a long conveyor. Toggles the machine to higher speed to clear upstream accumulation, then when the accumulation is reduced and the eye is cleared, speed reduces to normal rate.
E Ejection Verification: sensor confirms the ejection cycle of an Inspection/Ejection unit. A beam across the entrance of the eject tray is broken after each eject command to confirm the ejection has taken place. If the beam is not broken the machine is paused and the operator alerted.
Electrical Lock Out/Tag Out – locking cover which allows the padlocking of power switches.
Engraved Tags on Devices – The optional installation of engraved, lamicoid type labels onto photocells, near motors and sensors, etc. This is in contrast to standard marking which is a permanent laminated printed label, or a laminated hanging tag. Engraved tags are standard on operator panel switches.
F
Fallen Bottle Sensor – sensors to detect fallen containers at the infeed and/or discharge of a machine, which will pause the unit.
Film Application Jam Sensor – sensor which confirms that material is applied to the container and clears the application area in a timely manner. If it detects material longer than anticipated, the machine is paused.
Film Feed Jam Sensor – confirms the timely and correct flow of materials around the cutting and feeding area of the machine. If material is detected for longer than anticipated, the machine is paused.
Full Enclosure – Complete machine enclosure with safety interlocked doors, sometimes built from Bosch components. Standard on larger machines, optional on smaller machines which have compact interlocked guards.
H
Horizontal Perforator – a system to put consumer perforation where the closure meets the container, allowing the separation of the tamper evident portion from the rest of the shrinksleeve label, which remains on the product. The perforation can be of a range of types in terms of "cut-to land" ratio, which determines its strength and ease of opening.
Hot Stamp Imprinter – Heat transfer, ribbon type imprinting system used to print date and/or lot code information on sleeve on the flat web, before application to the product.
I
Imprint Verification – sensor which confirms that an imprint of a certain graphic density was placed onto the sleeve; not character recognition, which would be done with a vision system.
Indexing Conveyors w/Fixtures – conveyor mechanically linked to the drive of the application machine through an indexer (gearbox which advances a specific number of degrees and therefore advances the belt a certain distance every cycle.) Used for applications where a product is fed, either manually or by a robotic device, into the fixture and then presented directly under the sleeve application point. Indexing conveyor application speeds are up to 100 packages per minute due to the issues of inertia when indexing a large mass.
Inspection/Ejection Unit – for verification of the presence and/or location of a tamper evident seal or label, system utilizes either the visible or ultraviolet light spectrums. Ejection unit moves the product in question off the production line onto an optional tray or customer-provided bin.
K
Keyed Run/Jog Switch – mounted on the operator control panel, this keyed switch limits the jog function to those with a key such as a maintenance person.
L
Light Fixture in Main Electrical Panel – mounting of a florescent light fixture in large main electrical enclosure.
Line Pressure Relief Unit – for lines, typically beverage or food, with large amounts of product backpressure. The pressure relief unit is typically a star wheel mounted on an electronically controlled brake. When the machine is in the pause mode the brake is engaged, holding back the excess line pressure from the infeed of the machine.
Low Air Pressure Switch – monitors the air pressure coming into the system and pauses the machine if pressure drops below a preset level.
Low Material Sensor w/Beacon – sensor which reads the diameter of the material roll as it is consumed. Once a point close to the end is reached (this point is adjustable) a signal is sent to an indicating light which may be located on the control panel, touch screen, or light a beacon on top of the machine.
M
Material Out Sensor – If an operator misses a "Low Material" indication and the roll is fully consumed, this sensor will pause the machine and stop the material just after it comes off the core, providing enough material to splice in the next roll.
Motorized Height- Up/Down – Motorizes the up/down movement of the machine head during product changeover.
Motorized Height-w/Pre-Sets – as an enhanced version of the item above, this system has preset positions so the machine head goes to the selected position for a given size container.
Motorized Unwind Reel – provides for the motorized pay out of the material off the roll, controlled by a transducer or switches on a vertical slide assembly or sensor reading the web in a vacuum box.
P
PLC Control – (programmable logic controller) is standard on some models, optional on others.
Power Transformers – make allowances for customer specified electrical voltage controls.
Pre-shrink Unit – single or dual hot air guns, wired and integrated into machine functions, which apply precise amounts of hot air onto the just-applied tamper evident seal. Used when the band and closure are larger than the body of the package and there is no natural shoulder on which the band would rest (such as banding a tapered cup and lid). The heat guns shrink the band slightly, tacking it into position so it remains in place until reaching the shrink tunnel to complete the shrinking process.
R
Remote Jog – jog switch on a coiled cord.
S
Safety Interlocks – switches which electrically interlock hinged covers.
Scales and Gauge Blocks – graduated labels and mechanical devices used to speed changeovers and machine set ups.
Second Unwind Reel – additional reel station for the mounting of a second roll of sleeving material. Location may be under the conveyor or on the side of the machine.
Separate Dual Reel Unwind Stand – Remote welded stainless steel unit which holds two 24" unwind reels, low material sensors, material out sensor and splicing table. Separate from the machine frame, it can be parallel or perpendicular to the machine.
Servo Feed Motor – programmable and precise feed drive, standard on certain models, available as an upgrade on others, which performs fast and extremely accurate band feeding. Typically they are used for higher speed applications that require more accurate feeding than a clutch/brake (which is the standard on certain models).
Shrink Tunnel – stainless steel chambers of various lengths and types of heat used to shrink the sleeves once they are applied to the package. Heat sources include convection hot air, radiant infra-red and steam. See specific model information for specifications and more details.
Sleeve Locating Rollers – also known as Band Locating Rollers, these are rubber disks mounted on variable speed motors which insure the label is fully seated down to the conveyor.
Skidding and Wrapping For Shipment – standard method of preparation for domestic shipment. Heavy duty wooden skid is constructed specifically based on the systems dimensions, machinery is lagged to the skid with bolts so it will not shift in transit, and the system is then wrapped in transparent stretch wrap so the truckers and handlers can see the items being moved. Peripheral items and tooling are wrapped and boxed and securely mounted to the skid. Machinery is then shipped via air ride van lines, not common carrier.
Solid Stainless Construction – machining internal plates of the machine from 304 stainless steel, rather than anodized aluminum. Stainless steel machine frame is standard.
Splice Detection Ejection Upgrade – as an upgrade to the inspection/ejection unit, this option is the additional sensor and associated logic to detect and eject material splices.
Splice Detection Sensor – sensor mounted within head of the machine to detect splicing material within a roll of material. Can either pause the machine or sound an alarm.
Splice On-The-Fly Unwind Stand – PDC unwind stand which in addition to having two reels, splicing table, low material and material out sensors, also has a festoon unwind system that provides a buffer of sleeving material to allow the machine to continue to operate at half speed during the splicing process (40-50 seconds). The festoon material is driven by a separate drive. The operator mounts the new roll of material on the empty reel and gets a Low Material signal before the first roll runs out. When the first roll ends, the machine goes into the splice mode. If necessary the machine is cut to half speed while the operator splices to the new roll of material. Accumulation system includes the festoon, material clamp, and all required sensors and logic.
Splicing Table – device that facilitates the splicing of the end of one roll into the beginning of the next. Standard on some models. Includes material holder, cutting guide and tape dispenser.
Stainless Steel Covers – 18 gauge stainless steel covers used to protect personnel from moving components and pinch points.
Stainless Steel Frame – PDC standard frame construction is 2.5" x 2.5" 304(?) stainless steel tubing which is welded for sanitary environmental standards such as in food, dairy and pharmaceutical plants.
Stainless Steel Parts Package – Also known as Washdown Package. Typically includes stainless steel timing screw drive or product handling, collars, fasteners and shafts. On smaller models includes stainless steel main electrical enclosure.
Static Eliminator – utilizing either ionized air, or anti-static bars, this system dissipates the static electricity charge in the sleeving material which is the result of the sleeve converting or printing process.
Status Indicator Light Bank – multicolored stack light which indicates machine status and line conditions, such as: running normally, waiting for bottles, low material, material out, downstream jam, or customer specified conditions. Some sensors are optional.
T
Tear Tab Blades or Slit Tab Blades – available on certain models, cut off blades which produce a tab at the top of the sleeve for easy opening of the tamper evident seal.
Timing Screw Drive – Standard on most machines: the unit which holds and drives the timing screw, a helix with a pocket cut for a specific bottle profile which positively handles the container through the infeed, banding and discharge of the machine.
Tool-less Changeover – Conversion from one container format to another without the use of tools, or with the absolute minimum.
Touch Screen Interface – also known as HMI (human machine interface), has multiple screens of pushbuttons for machine sensors and speed controls, which can be pass-word protected at various levels. Connects to machine PLC and can be flexibly programmed.
U
UL Approval of Electrical Panel – obtaining UL (Underwriters Laboratories) inspection and approval sticker on the main electrical panel and enclosure.
Upstream Photo Eyes – also known as Choke Feed: two eyes which are mounted on the customeršs conveyor upstream of the machine to monitor product flow. These eyes automatically pause the machine in the absence of containers and restart it once product arrives at the machine. The eyes feature time delays for both on and off functions and for fine tuning the machine in relation to the line operation.
V
Vertical Perforator – This is a roller type of cutting blade that cuts the perforation in the material so that when the bottle or package is opened the material is damaged and is therefore tamper evident.
W
Washdown Package – Also known as Stainless Steel Parts Package. Typically includes stainless steel timing screw drive or product handling, collars, fasteners and shafts. On smaller models includes stainless steel main electrical enclosure.
Z
Zero-Access Guarding – special enhanced guarding that keeps operators away from all moving areas.
