The horizontal spiral accumulator design is based on the principle of the difference in the length of an equal number of spirals around different diameters. This system allows to accumulate a big quantity of strip, in regards to the occupied area and it works in spiral mode. Moreover, this machine doesn't need special on-site construction work and can be easily moved. The completely automatic operation allows to exploit totally the economic advantages offered by a continuous production.
The entry end strip deviator( twisting unit,horizontal unit) and driven pinch rolls guide the strip from the horizontal exit of
the shear and end welder to the vertical pinch roll of the accumulator.
The horizontal spiral accumulator is filled by the pinch roll driven by the A.C. motor and with pneumatic
cylinders that give the pressure to guarantee the friction with the strip.
The drive system for the rotation table is composed by one AC motor with one reducer and cardan shaft.
The rotating motor and pinch motor are controlled by a frequency variable system. The strip exits from the center of the accumulator and is again angled horizontally by one high horizontal support roll to the forming machine
1)Twisting unit to guide the strip at the entry of the rolls-feeder
2)Rolls-feeder (called introducer) driven by a AC motor to feed the storage
3)Storage (called accumulator) with revolving table driven by AC motor
4)Exit guide unit to conduit the strip at the exit of the machine.
5)Console
●Large storage capacity
●Minimal maintenance
●Low noise
●Synchronized operation: inlet and outlet speed are the same as the line.
●During welding the coil end/head. In this phase, the line takes the material stored in the accumulator.
●When the welding process is finished, the inlet speed is higher than the outlet speed to quickly accumulate the strip amount used during the welding phase.
●When the defined amount of strip is reached, the machine automatically synchronizes with the speed of the tube line.
