Introduction

A SHANKLIN Overhead Harmonic Infeed continuously feeds product smoothly into an F-5 to produce the required spaciong between products.

The SHANKLIN F-1, F-5 and F-7 FIoWrap machines are continuous motion horizontal "Form-Fill-Seal" machines designed to wrap packages in plastic film (usually shrink film). The Models F-1 and F-7 have a belt infeed conveyor and are capable of wrapping packages at speeds up to 50 packages per minute. The Model F-5 has a flighted infeed conveyor, and because of its product feeding systems, can wrap products at speeds up to 75 packages per minute.

These highly versatile machines run equally well at both high and low speed, and their speed can be adjusted at the control con sole. The resulting packages have neat, welded bead trim seals on three sides of the package with no overlap seams on bottoms or ends of the packages.

The F-1, F-5 and F-7 use centerfolded film which is readily available. Some customers prefer to use flat film folded by an optional SHANKLIN centerfolder. In either case, the inverting heads on the machines do not require a precise matching of film width, thus permitting many sizes of packages to be run with a moderate selection of film widths.

A further advantage of the side sealing system is that the film can be pulled toward the side seal jaws as it is being fed through the machine, thereby producing a tighter wrap than is possible for the bottom lap seal machines. In addition, the welded bead seal is a more positive seal than the overlap static seal.

A SHANKLIN Flight Bar Infeed simplifies hand loading product. Particularly useful for multipacks or packs with dissimilar products.

Description - Model F-1

The SHANKLIN Model F-1 accepts product arriving at the machine randomly spaced and establishes the correct product spacing by means of a series of precision timed and sequenced conveyors. The flow of product through the machine is a straight line and is relatively gentle.

The machine consists of a rugged main frame on which are mounted a series of conveyors to carry product through the machine. The electrical control system sequences the conveyors to space product properly.

Folded film or film being delivered by a centerfolder feeds to a film inverting head which opens the film, turns it inside out, and wraps the film around the product. A conveyor carries the overwrapped product past a side sealing area, where a weld bead is made on the film and the excess film is trimmed off. From there the package is conveyed to a moving jaw end sealer, which forms the weld bead seals on the end of the product and severs the package from succeeding products.

A SHANKLIN Dual Roll Centerfolder uses flat film.

Description - Model F-5

The SHANKLIN Model F-5 is similar to the Model F-1 with one major difference. The infeed conveyor of the F-5 is a flighted lug conveyor, and although it cannot accept random spacing of product, it will permit the machine to operate at somewhat higher speeds than the Model F-1. An additional consideration is that some product is better handled on a flighted infeed conveyor, and for this type of product, the Model F-5 is ideal.

The side sealer and transverse sealer of the F-5 are identical to those on the F-1, and they produce the same neat appearing package, with trim seals on three sides and no overlap bottom seal.

Description - Model F-7

The SHANKLIN Model F-7 is similar to the Model F-1 except it is much larger in size capacity and is designed with heavy duty conveyors to wrap larger and heavier products.

Operation - Model F-1

As product arrives at the machine, it is carried to a "ready" position by the infeed conveyor. At precisely the right moment, the infeed conveyor feeds the product into the main conveyor system so that it is spaced the proper distance from the preceding product. The conveyors carry the product through a film inverting head where it is surrounded by film. As the products pass by the side sealer, a thermal sealing mechanism seals the free edges of film with a neat welded bead seal, and the selvage trim is removed by a vacuum system. The film with product sealed within is then conveyed to a traveling end sealer that seals the leading and trailing edges of the packages while simultaneously severing individual packages from the moving web of film. Upon completion of end sealing, the package is conveyed out of the machine, usually to a SHANKLIN Shrink Tunnel.

Operation - Model F-5

Operation of the Model F-5 is the same as the Model F-1 except that products are carried continuously into the machine on a flighted infeed conveyor, thereby permitting higher speeds.

Operation - Model F-7

Operation of the Model F-7 is the same as the Model F-1.

Shrinking

A SHANKLIN Shrink Tunnel, located at the discharge end of the wrapping machine, shrinks the film tightly around product to give the completed package an attractive appearance. A comprehensive line of SHANKLIN Shrink Tunnels meets the needs of virtually all applications.

A SHANKLIN Multipacking Infeed accumulates multiple products. Using a cross bar, as shown, or alternativec side bars, the multipacks are released into the F-1.

Changeover

Size changeover on the F-1 is simple. The product spacing and end seal placement are easily adjusted on the control console to accommodate product length and spacing changes.

For product height and width changes, reset the infeed conveyor guides and change or reset the film inverting head. If necessary, replace the roll of film with one of appropriate width. Adjust the side sealer position laterally to suit the product width and vertically for the product height. Reset the end seal jaw opening to clear the package height. The machine is now ready to use. The procedure for the F-5 machine is similar to the F-1, except that product length changes are accomplished by changing the conveyor lug spacing and conveyor variator servo settings.

Controls and Adjustments

The SHANKLIN F-1, F-5 and F-7 FIoWrap machines are equipped with programmable controllers with user-friendly touch screen control panels, which allow easy machine set-up and adjustment, assist in operator set-up, perform diagnostic checks and control machine sequencing.

The Diagnostic routines and status display are standard, helping the operator to quickly find a stoppage or a malfunction and to monitor the condition of the machine. The programmable controller has an optional data network capability.
