Inverted Power and Free Conveyor

Design of Inverted Power and Free Conveyor

The Power and Free floor conveyor, which is the most technically complex type, offers asynchronous conveying. Each set of trolleys can stop and start independently and move loads at different speeds.

Power & Free floor conveyors are based on a dual profile system. The upper ‘free’ profile is used for the trolleys and the lower ‘power’ profile is used for the power chain. Pusher dogs are fitted to the power chain at the same pitch and are used to pull the carriers around the system.

Stop stations are used to disengage the link between the power chain and the trolleys. When a stop station is closed, the carrier stops while the power chain continues to move. Due to the design of the pusher and trolley, several carriers can accumulate behind a stop station.

This heavy duty conveyor is a self accumulating Power & Free system, setting a new solution when it comes to handling the largest, and heaviest, unbalanced jigs.

Developed for applications where the need for Power & Free technology is required in sections such as storage areas, ovens etc. where space is at a premium, but where general process areas only require fixed pitch operation. Supreme accuracy in guiding is secured by the 4 horizontal guide bearings as well as the fully adjustable “Free” track. Compared to traditional skid systems or roller conveyors, the Power & Free floor conveyor system operates with high reliability and smoothness. This is due to the limited use of drive units and sensors, requiring a minimum of effort and interference from the control system.

Today, our floor mounted power and free conveyor systems operate in a wide range of demanding industries. Usually supplied with a frequency converter to achieve the desired production speed. Floor mounted Power & Free conveyors are used for assembly lines, paint lines and also in combination with robots.

Applications of Inverted Power and Free Conveyor Systems

Inverted Power & Free Conveyor transports the product on a pedestal, therefore production line operations can be performed quickly and efficiently without obstruction. The power and free inverted chain conveyor system may be mounted on the floor, flush with the floor, or at building truss height to accommodate plant conditions.

In contrast to the Overhead P&F conveyors, the floor based Power & Free system puts the conveyor down at floor level with the part above. This in-floor chain conveyor system can be useful for lighter parts that do not easily lend themselves to be hung from overhead conveyors. This Power & Free Enclosed Track Inverted Conveyor also offers much cleaner environments for painting as there is no conveyor overhead to drop contaminate down on to the parts.

With different structure, the conveyor can be made as inverted power and free chain conveyor system, inverted power and free monorail floor conveyor system, inverted floor mounted power and free conveyor system and friction drive inverted power and free conveyor. For automotive industry workshop, it always designed as towline floor conveyor, which is mounted on the floor towline conveyor system.

The Inverted Power and Free Conveyor Systems are used for production areas or delivery systems that require accumulation such as general assembly lines, manufacturing plants, warehouses, body shop, surface treatment, paint finishing system, powder coating, spray painting and oven drying. They are well-suited for handling a wide variety of products, including automotive parts, appliances, electronics, and food and beverage products. This heavy duty Power & Free floor conveyor can realize multiple functions including: Accumulating, Bias & Trias Banking, Carrier Indexing, Elevation Changes, Production Rate Variation, Segregation, Sort, Start/Stop, Storage, and Transfer.

Inverted Power and Free Conveyor Accessories, Components and Inverted Power and Free Conveyor Spare Parts

The Inverted Power & Free monorail conveyor system, consists of two profiles. In the lower “Power” profile the power chain is driven by one or more drive units. In the upper “Free” profiles the purpose designed trolley and wagon sets are driven by power chain carriers, via pivotal pawls attached to the front and back of the trolley.

The trolley body is made of laser cut and folded plates and is equipped with 4 sealed load carrying wheels and 4 sealed horizontal wheels for side guiding, which runs through floor conveyor track.

Both the power chain carrier pitch and the accumulation distance are designed according to customer specification and requirements.

Each trolley and wagon set can be separated from the power chain and accumulated in line, 45° or 90° zones. When reaching a closed accumulation stop or when reaching the tail of the previous trolley, the accumulation lever is lowered and the trolley pawl units are lifted.

Conveyance with loads in rise and fall sections is possible due to a uniquely designed link between the chain carriers and the trolley pawls.

Other available components and spare parts are universal link chain, drive units, enclosed track, tension, Power & Free trolleys, Power & Free track, Caterpillar drive unit, jigs, tension, Take up, switches, lubrication units, tension units and rotation devices.
