PosiGrip Accumulation Conveyor From TKF Allows Non-Contact Conveying Around Virtually Any Degree of Curve

PosiGrip Accumulation Curve ConveyorTKF’s popular PosiGrip accumulation conveyor can be configured to convey product around virtually any degree of curve, while maintaining non-contact, zero pressure accumulation. The system is ideal for the computer and electric component, food and beverage, appliance, automotive, and glass industries when non-contact between products is crucial.

Accumulation zones are driven by motorized rollers, each with a drive card that allows easy adjustment of speed. The drive roller stops as product reaches the photo-eye at the discharge point of the zone, virtually ensuring no contact. Zones can be individually controlled for specific assembly areas and are available in various widths. When used with TKF’s PosiGrip Accumulation Conveyor, the curve allows for uninterrupted accumulation with no external sensors or logic required.

PosiGrip roller drive gear teeth are formed directly into the rollers and powered by smooth, quiet synchronous belting in a positive drive. This provides superior drive force compared to line shaft and O-ring styles of conveyors.

The rollers are driven by belts so there is no metal-to-metal contact resulting in quiet operation. It requires no lubrication, and there are no separate sprockets, gears, or welded drive components making it cleaner and easier to maintain than comparable conveyors. PosiGrip is ideal for most any work condition, and runs smoothly in both clean and tough, rugged conditions.

Counterweighted Lift Mechanism Reduces Horsepower and Power Requirements on TKF’s Reciprocating Vertical Conveyors

Reciprocating Vertical ConveyorTKF’s line of reciprocating vertical conveyors feature counterweighted lift mechanisms that cut the effective unit load weight in half, thereby reducing horsepower and power requirements. Standard models are available with unit load capacities up to 6000 lbs, with a vertical travel of up to 100 ft.

Load and unload points can be incorporated at any height, and on any side of the unit. This permits “Z”, “C” or right angle flow. Lift speeds can range from 10 – 200 FPM, using either chain or belt drives, with the higher speeds made possible with variable frequency drives.

The bed, while typically constructed of roller conveyor, can be designed using virtually any type of conveyor, including TKF's innovative PosiGrip.

Other features include a 4-post design; full top to bottom guarding regardless of load capacity; and a shaft-mounted drive that reduces maintenance requirements, without a loss in horsepower.

TKF’s reciprocating vertical conveyors are used in a wide variety of applications where items need to be moved from one level to another, including basements, mezzanines, balconies, or within multi-story buildings; or even from building to building – manufacturing to warehousing for example.

Enhancements to Valu-Lift™ Vertical Conveyors From TKF Result in Lower Maintenance Requirements, High Speed

Valu-Lift Vertical Continuous LiftTKF has improved on its popular Valu-Lift™ Vertical Conveyor, redesigning the systems take-up and stub shaft assemblies to utilize internal ball bearings as opposed to bronze bushings. This design enhancement greatly reduces maintenance issues, and increases the life of the assemblies.

The Valu-Lift vertical conveyor is a four-strand, continuous lift, light-duty conveyor designed to handle cartons and other smooth-bottom unit loads up to 50 pounds. It offers economical modular construction and a patented platform designed specifically for efficient high-speed operation, low maintenance and simplified and quick assembly.

The unique platform design consists of simple, lightweight interlocking molded polymer flights with steel connecting pins and lifts at a maximum speed of 118 fpm. The conveyor can operate in up, down or reversible mode.

Standard net lifting heights range up to 20’-0” with customized heights available. The Valu-Lift’s maximum unit load is 50 lbs., with a length of up to 26”, and width of 16”,

Standard safety features include a 24 volt DC control, a current sensing relay, which instantly shuts down the conveyor if it is overloaded, totally enclosed shroud-type tunnel guards and a smooth, clean design.

Flyer Describes TKF Zoned Accumulations Conveyors That Provide Safe, Reliable Non-Contact Accumulation

A four-color flyer describes all the advantages of the TKF Inc. zoned accumulation conveyors, which are zone controlled for safe, reliable non-contact accumulation of even the heaviest, bulkiest loads.

The capacities of TKF zoned accumulation conveyors range from 20 lbs. to a maximum of 5,000 lbs., making them suitable for a wide variety of applications. The flyer provides full specifications for conveyors available with either medium duty 1.9" or heavy duty 2.5" roller diameters in widths up to 60", depending on load and roller size.

A single assembly consists of a roll-to-roll chain driven live roller (CDLR) conveyor divided into individually powered zones of a pre-set length. A single power unit drives the entire conveyor length, and each zone is driven by an air-controlled clutch, controlled by a pneumatic sensor at the end of each zone.

When a load enters the TKF zoned accumulation conveyor, it is driven to the farthest unoccupied zone. The load actuates the sensor at the end of that zone, which disengages the zone’s clutch and readies the succeeding zone.

When the next load reaches the end of the succeeding zone, its clutch is de-energized, and the sequence is repeated until all zones are filled. When a load is removed from the conveyor’s exit end, its sensor is disengaged, signaling the accumulated loads to move up in sequence, filling the next vacated zone.

Unlike most other conveyor designs, the TKF zoned accumulation conveyor offers a compact configuration — as little as 6" from floor to top of roller — since the complete clutch assembly is within the side frame rather than underneath.

The TKF design is clean and simple, so TKF zoned accumulation conveyors run quietly and require little maintenance. Engineered for low air consumption, the conveyors use standard, plant quality compressed air.

The flyer also describes the available options which include standard channel side frames, reversing operation, online workstations, special widths to 60", special zone or section lengths, solenoid-operated zones, zone brakes, and “batch release” controls.

TKF specializes in the design and manufacture of engineered conveying systems for the appliance, packaging, automotive, food/drug preparation and other manufacturing and processing industries. Conveyor types include vertical, accumulation, carousel, overhead, and transfer units.

TKF’s PosiGrip is Available in a Variety of Configurations to Solve Many Material Handling Applications.

PosiGrip from TKF is a powered, non-contact, zero pressure accumulation conveyor system and is available in a variety of flexible configurations.

  • PosiGrip comes in both standard motor driven and motorized roller driven zero pressure accumulation styles. It is available in standard sizes from 18" to 45" effective widths and zone lengths from 15" to 60". Other sizes are available upon request. Capable of running from 25 to 120 FPM with roller centers of either 2 ½” or 3 ¾”, and unit loads of up to 400 lbs. per zone, PosiGrip will meet the needs of most conveying requirements.
  • PosiGrip driven roller curves are available with a 32 ½” inside radius and 18" to 42" effective widths. They can be equipped with straight, tapered or true tapered rollers. Special radius and widths are available upon request. When used with the company’s PosiGrip accumulation conveyor, the curve allows for uninterrupted accumulation with no external sensors or logic required.
  • The PosiGrip lifting gate section creates a unique and effective solution when access behind or through a conveyor section is required. The units come in standard PosiGrip widths of 3'-0" or 4'-0" openings and can be built to meet specific requirements. It is self-contained and operates on a standard 110V electrical supply. A gas spring assists in the lifting mechanism. The result is a relatively lightweight and very economical and dependable gate section.
  • While TKF’s popular popup transfer lifts do not utilize PosiGrip rollers, they can be incorporated into a PosiGrip conveyor system. They lift items vertically, and then conveys them 90° to an adjoining conveyor. The system utilizes a mechanical linkage to guide lifting. Strands are driven by a motorized roller, eliminating chain drives and resulting in quiet operation. There are no vertical guides or cam ramps used for positioning, and no slides or bearings used in its construction, making the pop-up transfer conveyor simple to maintain. They are compact and utilize state of the art patented low maintenance design components. Available in either V-Belt, O Belt, Timing Belt or multi strand chains configurations, users have a choice of 2, 3 or 4 strands with spreads between 10 3/4" and 33 1/4" standard, with alternatives available upon request.

In all PosiGrip configurations, gear teeth for the roller drives are formed directly into the rollers and are powered by synchronous geared belting in a positive, non-slip drive configuration. The geared design provides superior drive force versus line shaft and O-ring driven conveyors. Each motorized drive roller includes a drive card that allows easy adjustment of speed in each zone providing complete control over product spacing. Since the zones are powered independently of one another and only when required, power consumption is minimized.

There are no separate sprockets or gears and no welded drive components. This results in a low-maintenance, compact and low-profile design. Since there is no metal-to-metal contact, product life is extended, there is no lubrication required, and operation is clean, smooth and quiet.
