Introduction

The SHANKLIN Model HS-2 High Speed Automatic Wrapper is designed to wrap products in plastic film, usually shrink film, fully automatically at speeds up to 100 packages per minute or up to 120 linear feet of film per minute.

The SHANKLIN Model HS-4, with its extended speed capability, can wrap packages at speeds of up to 200 packages per minute or up to 200 linear feet of film per minute depending upon the package and the application.

These highly versatile machines run equally well at both high and low speeds, which can be adjusted at the control console. The resulting packages have neat trim seals on both ends and a transparent overlap seam on the bottom.

Each machine is ruggedly built for high performance, reliability and ease of maintenance. Product size change-over can generally be accomplished quickly and easily, and operating speeds can be matched to your production line by simple adjustments at the control console.

Description

The SHANKLIN Models HS-2 and HS-4 High Speed Automatic Wrappers combine high speed and smooth product travel through the machine with quick and easy size change. They will wrap low, medium, and high profile products automatically. Although the machines perform a complex function, they are designed and built with customer service in mind, thereby facilitating distributor installation and customer maintenance.

Operation

Products are fed continuously into the machine on a flighted infeed conveyor. Flat film is delivered to the forming head from a powered film unwind that feeds the film at a constant, uniform tension. The film is then drawn over the forming head, creating a tube of film around the product.

Film edges are overlapped on the bottom of the product and are sealed together with a static sealing system that can be adjusted for varying speeds and climatic conditions. (A thermal seal is also available.) The product is conveyed through the machine by a vacuum conveyor located immediately downstream from the forming head.

Product arrives at the end sealing conveyor and passes through the end sealer jaws. On the HS-2, a photoelectric cell activates the jaws to close. On the HS-4, the cross seal jaws are tied with the infeed conveyor and will close between packages automatically.

The jaws seal the ends of the packages and sever individual packages from the tube of film. The jaws travel with the package to permit continuous package movement through the machine.

Shrinking

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

Changeover

Size changeover is relatively simple. With the Model HS-2, the infeed conveyor speed and lug spacing are easily adjusted to achieve correct package length and desired package spacing. End seal placement is adjustable from the control console. With the HS-4, the infeed conveyor lug spacing is set, and then the main conveyor speed is adjusted to determine cut-off length. Once the cut-off length is set, the cross seal carriage speed is set on the drive crank, and the cross seal is synchronized with the package position.

Changes in package width and height are made by setting the infeed guides and changing the forming head to suit the product. The end seal jaw is adjusted to clear the product and the closure is set to the midpoint of the package. A change in film width may be required although many sizes of product can be run with a moderate selection of film widths, thereby speeding up the product changeover procedure.

Value Added Features and Options

A SHANKLIN Overhead Harmonic Infeed continuously feeds product smoothly into an HS-2 to produce the required spacing between products.	A SHANKLIN Side Belt Harmonic Infeed continuously feeds product smoothly into an HS-2 to produce the required spacing between products.
A SHANKLIN Synchronic Overhead Belt Infeed places product smoothly and with precision into the flights of the infeed conveyor on an HS-2 and HS-4.	A SHANKLIN Adjustable Flight Bar Infeed simplifies hand loading product, particularly useful for multipacks or packs with dissimilar products.
A full range of forming heads are available to suit all sizes and profiles.	A SHANKLIN Standard Overhead Film Unwind with film being fed to the forming head.

Product Infeeds

Depending on product type and production line operation, the following options are some of those available for feeding products into the infeed conveyor of the HS-2 and HS-4. Consult factory for additional systems.

Product Infeeds for HS-2 and HS-4:

• A SHANKLIN Synchronic Feed for continuous product flow feeding.
• A SHANKLIN Right Angle Feed with "no product' detectors (Product can be fed from either side.)
• Timing Screws for continuous flow feeding of round product.
• Hand-feeding of product where suitable using the extended infeed conveyor

Additional Product Infeeds for HS-2:

• A SHANKLIN Harmonic Feed for continuous product flow feeding.
• A SHANKLIN Automatic Product Placement Conveyor.
• Wide Flight Bar Infeed for multipacking.

The flow of accumulated product upstream from the infeed conveyor of the machine is essentially smooth and continuous with the SHANKLIN Harmonic Infeed, The SHANKLIN
Synchronic Infeed, and the Timing Screw Infeed. Synchronic Infeeds and Timing Screw Infeeds are designed for all SHANKLIN High Speed Wrapping Machines. They are used to place product between the flights of the infeed conveyor smoothly and continuously at high speeds.

Harmonic Infeeds are installed on modified HS-2 Wrapping Machines which are equipped with belt infeed conveyor systems instead of the flighted infeed conveyors. The Harmonic Infeed is a simple, versatile way to achieve smooth, continuous product feeding at HS-2 speeds.

Controls and Adjustments

The SHANKLIN HS-2 and HS-4 High Speed 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.

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.
