AUTOMATIC SPACER PLACER
A spacer placer automatically places three or four wooden spacer blocks radially on top of a slit coll so that another coil can be placed on top. This allows multiple slit coils to be packaged together on a single pallet without being damaged. Coils can then be easily un-packaged and handled by a fork truck at the final destination.
Spacer placers can be designed to position the spacers in different configurations, depending on coil size and downstream operations. The automatic placers allow operators to do other tasks instead of manually placing the spacers. This reduces repetitive work Injuries and improves operator safety. Automatic spacer placers may be added to existing packaging lines as they are independent of the coil conveyor. The placer simply needs a position in the line where the coil is automatically centred on the conveyor. The unit consists of a spacer gripper mechanism that can move in the three axes and has a vibratory hopper, a small parts conveyor system, and a control system.
FEATURES
|
-
Spacers are uniform and pre-cut
-
Three different lengths of spacers can be placed
-
Mults are automatically centred on the conveyor beneath the placer

|
COIL STACKERS
Coil stackers are used to place multiple slit coil mults on one skid and to sort coils into various customer orders. Stackers can be arranged to provide inline stacking or right angle configurations. The orientation of the stacker is dependent on the customer's plant layout and material flow. Stackers can be fully automatic, as shown, semi-automatic or manual. Stackers can pick up and stack coils using Coil lift forks, Magnet lift heads or Vacuum lift heads.

SKIDDED COIL STACK PACKAGING
The usual stack packaging process involves:
-
Weighing the skidded stack
-
Securing the coil stack to the skid with either Steel or Plastic Strapping or Stretch
Film Wrapping and Roping
-
Visual checking of shipping package and application of shipping labels
-
A stretch film wrap and top sheet application is often used to seal the secured coil
stack
Skid Banders

SKIDDED COIL STACK HANDLING
Eye-to-Sky Handling
|
 |
Slit mults may be removed from the storage coveyor with a fork lift or crane and telescopic pallet filter. |
Coil Tipping to Eye-Horizontal Handling
|
 |
Sometimes, after the coil is packaged in the eye-vertical position, the coil must be tipped up into the eye-horizontal position for shipping to the customer. Typically, wide coils, greater than 15 inches, are shipped this way. An in-line upender will tip the coil stack through 90° to eye-horizontal position for removal by a C-hook or pole truck.

Weighing and Ticketing
 |
A weigh scale typically plants a "ticket" that is attached to the skid of coils. This "ticket" includes information such as weigh, customer name, barcode, etc. |
COIL TIPPERS
During many stages of the slit coil packaging process, coils and slit mults must be rotated between eye horizontal and eye vertical. Depending on the specific application, there are several types of equipment that can accomplish this type of rotation.
Slit Mult Lifters
 |
Slit Mult Lifters are used for moving a single slit coil between vertical and horizontal positions. The lifters are made of high strength steel and the inside corners are polished and NDT inspected. Bushman AvonTec's Slit Mult Lifters can be custom-designed for various capacities and coil sizes. The available capacities range from 500 to 10,000 pounds. |
|
|
This specially designed lifter facilitates fast and safe placement of a slit coil onto an un-coiler mandrel. The lifter automatically adjusts to various coil diameters and the full length handle makes it easier to manoeuvre. This Slit Mult Lifter is also faster and safer to use than a conventional C-hook. |
