Coil-upender machines are used in a wide variety of situations including wrapping, roll-up, and other forms of straight rope and soft rope applications. These machines allow the fabricator to cut or wrap large areas of foam without having the coils exposed to harsh chemicals. When the two halves of the coil are loaded into the upender they are forced together by the hydraulic arm. This forces the coils to be sealed against each other resulting in a tighter weave and ultimately a more consistent diameter of the foam. This results in a tighter product, smoother finish, and less damage to the fabricator.
The Hydraulic Coil Upender Machine is a high-speed custom built rigid Tilting Hydraulic machine with a maximum capacity of up to forty-two T. This Hydraulic flat tilter machine is equipped with two independent hydraulic arms with interchangeable sprockets on both sides of the machine. The up raise process requires lifting one half of the sprocket at a time and loading the other half into the upholder against the former half. Next the sprocket rotates either half of the coils simultaneously which turns both halves of the coils around simultaneously, which also rotates or twists the tool ninety degrees to allow for easy servicing. This allows for a paper roll to be preloaded into the spool and eliminates the need for using cuttings.
The Electric Coil Upenders uses an electric motor with a control to vary the speed of the rotation of both halves of the spindle arms. The Electric Coil Upenders can be used with rubber or foam core upenders or paper rolls. These are similar to the Hydraulic upenders, only these do not use hydraulic power to raise and lower the coils.
Another type of coiled under is the Tipper. Tipper coiled upenders are typically used in warehouse operations where heavier items need to be lifted from pallets. The purpose of a tipper coiled upender is to increase the load capacity of the conveyor, thereby increasing the throughput capacity of the assembly line. Tipper coiled lenders have a T-shaped arm with one end fitted with a drum which has one end fitted with a blade that is driven by a motor to rotate the blades. A variable speed electric motor is fitted to the drum in order to regulate its speed.
In addition to being used to lift heavier loads, Tipper Coils also has the ability to tip items. Tipping is a manual operation similar to feathering. Tipping a load causes the load to tip over the rim of the feeder. The feeder rim then causes the contents of the feeder to spill over onto the ground. To prevent the contents of a feeder from spilling onto the ground you should coil lenders that can tip.
Tipping is an operation that is best done by machines. But, there are some instances where manual operation may be required. The most common scenario for this is when the load being lifted is lighter than the coil lenders can handle. When this happens the machine will tip the load and the contents will spill onto the ground. In order to prevent this from happening you should train your coil upenders to perform the tipper operation in a controlled manner.
