Complete automation of pipe extrusion lines

Italian polyolefin pipe producer Wavin has invested in complete automation for extrusion lines, by adding two pipe packaging machines and one picking machine to one of its lines. The packaging machines (Multipack model) and the handling machine (Multipallet model) are produced by Sica, Italy. Wavin’s decision to invest in complete line automation arose from the need to reduce production costs and increase efficiency and line productivity.

Sica Multipack machines create individual pipe packs composed of various layers of pipes, deposited in plastic separator cradles, and then tied together by plastic straps. The system was specially developed for installation in lines producing pipes between 50 and 160mm in diameter and from 500 to 3,000mm in length (plus bell end). The company’s Multipallet machine for pipe handling picks incoming packs, rotates them if necessary, and places them on

New concept positioner for welding Rotolift, from Sideros Engineering, is a hydraulic positioner and handler used for welding and assembly operations. The ergonomic machine has the capability to perform workpiece lifting and lowering, in addition to inclination and rotation.

 The new machines have enabled complete automation of the company’s extrusion line

The workpiece is securely fixed on the horizontal rotary table and handled according to the operator’s needs. The machine is designed to improve operator performance and efficiency, and to improve safety conditions. Sideros Engineering claims that production costs can be reduced by 60 per cent, with a consequent production increase.

trolleys in predetermined layouts. The machine also picks separator boards from dedicated magazines and places them between layers, to increase the stability of the stack. The system is able to process packs varying in width between 290 and 620mm, with a maximum height of 400mm. Maximum productivity declared by Sica for pick up of a single pack and its positioning on the cart is 35 seconds for each pack. With the introduction of the new system, the operator can achieve complete automation of pipe extrusion lines, with cost reduction, increased process reliability and optimised working conditions.
