Consisting of:
Payoff:
The (2) payoffs are horizontal stands. Material is stacked on a special skid, separated with cardboard squares and placed on top of the stand. The coils are payed off from the top coil down. Back tension is generated by the weight of the coils. This is a very simple yet effective method.
Edging Machine:
The Edging unit consists of: -(2) entry strip guides -(3) tensioning drums -(1) edging head -(3) pull drums
Entry Strip Guides:
The guides will position the strips as they enter the edger. The guides will provide vertical and horizontal alignment.
Tensioning Drums:
The (3) tensioning drums provide braking against the (3) pull drums. This is to provide adequate web tension on each strip as it is machined. The first two drums are rubber coated and the third is cast iron. The third drum establishes the correct vertical pass line for the carbide edging cutters. To eliminate material slippage a braking roll is activated when the machine is running.
Edging Head:
Two edging stations are provided on a machined base. The tooling configuration will be flexible to allow for (2) strips at a time with (2) stations or (1) strip at a time with (2) stations with a max. width of 4.0". This flexibility is necessary when edging heavier gauge materials. The tool holders will accept a 0.750" x 0.750" x 0.375" thick carbide insert. Compressed air will flow through the tool holder and blow air directly on the point of cut. This air system will not only extend the life of the tool but, will help remove the chips generated while machining. The edging head will have large holes near the cutting stations where the chips will fall. A pan, located under the table, will collect all chips. Automatically operated pneumatic felt wipe stations will be located at the front and rear of the edging head for noise dampening.
Straightener:
Durant 7 Roll Straightener, 3 over 4 Rolls, Exit Pinch Rolls Pull Thru Operation
Pull Drums and Braking Drums:
This system generates controlled tension at the edging head. The tension system is designed to isolate itself from the rewind drum. After leaving the last pull drum the line tension is zero. This allows the operator to adjust the rewinder with great sensitivity. Without pull drums, the tension levels needed to edge would be greater than the required rewinding tensions, making it impossible to rewind narrow width materials. The machine will have a total of (6) drums. (4) of the drums will be rubber coated while the others will be cast iron. The cast iron drums will be mounted directly before and after the edging head. Cast iron is used to eliminate the chance of the strip welding to the drum. All of the drums will be driven by a serpentine drive system. This guarantees the drums are all turning at the same rpm eliminating strip slippage, a common cause of surface imperfections.
Rewinder:
The drive motor of the edger will drive the rewinder and tension will be regulated with a Horton TCC-10 pneumatic clutch. An expandable 16" dia. Drum will be used. An overarm separator unit will be placed in line to be used in lieu of plates.
Mechanical Specifications:
-All mechanical assemblies are located on a Blanchard ground surface. Alignment is maintained with keyed motor mount plates.
-All bearings are piloted flange mount type. All bearings nest in a bored hole. This is a more expensive way to manufacture but guarantees alignment. This is critical because of the tension on the strip that this process creates. If the shaft alignment is not perfect, the strip will not maintain a straight horizontal pass line. This can impact your product and package quality.
-All lubrication points are plumbed back to a centralized lubrication manifold. This allows access for greasing.
-All mechanical drive systems are made of Gates Poly-Chain. This is a timing type belt with kevlar reinforcement. This drive system requires zero lubrication, does not stretch, and is extremely quiet.
Electrical Specifications:
-20 hp ac vector motor - 1750 rpm, 480 volts, drip proof, self-ventilated -Siemens 20 hp drive -Nema 12 enclosure with through door circuit breaker. -Allen Bradley pushbuttons - start/stop/jog, speed pot, emergency stop, amperage meter and foot/minute meter. -Dynamic Braking
-Line direction: Right to Left
-Line is removed and in storage
