Three cranes and six Verlinde hoists in the injection mould maintenance workshop at Parker Hannifin

Wednesday, March 1st, 2017

PARKER HANNIFIN with its global turnover of Euros 11.5bn is a world leader in movement and control technologies. The company designs, manufactures and markets a wide range of hydraulic, pneumatic and electromechanical components. The Muzillac factory in Brittany employing 130, located 25 km from Vannes, is a plastics injection specialist for products of the FSCE division and for the automatic assembly of instant fittings The factory is ISO 9001, ISO 14001 and ISO TS certified and the injection mould maintenance workshop very recently installed three EUROPONT overhead cranes on each one of which is fitted two VERLINDE hoists.

 

The moulding workshop.
The moulding workshop is the core production activity at the Muzillac plant. Twenty-two Engel, Fanuc or Ferromatik injection presses are served by a overhead crane fitted with a 3-tonne VERLINDE EUROCHAIN VR Vario electric chain hoist for mould changing operations. These presses are used for the moulding of connectors for small pneumatic hoses and for compressed air system couplings in industrial buildings. For the car industry, five presses are dedicated to the production of motor fuel distribution circuits integrated by Parker Autolive in its manufacturing facilities. Mickael Le Pon, injection facility production manager, explains.“We carry out between 300 and 350 parts series changes per month involving just as many injection mould changes. To ensure the moulding workshop works at full capacity it is first of all vital that the moulds are in perfect condition and as their manipulation can only be carried out with the crane, the latter must be totally available and reliable.”

 

Mould routine maintenance, a decisive production factor.
Mickael Lepon: “Even if our activity is complex, it has to be understood that it is based in the main on two basic equipment units – plastic injection presses and moulds. To ensure production quantity and quality in phase with our targets, we have to ensure without fail regular inspections and routine maintenance of the moulds because we depend to a large extent on them to guarantee the productivity and the manufacturing quality of our products.”

 

A special workshop for mould routine maintenance.
The 500 m² workshop dedicated to mould routine maintenance consists of three successive square 10 m x 10 m work stations. After a certain number of duty cycles, the mould is removed, cleaned ultrasonically and the toolmaker is sometimes required to recondition the spindles by electro erosion or replace possible faulty parts.

 

Installation of suspended cranes and VERLINDE EUROCHAIN VR Vario hoists.
Before the EUROPONT cranes were installed, a single jib crane served the three work stations. As the manipulation of metallic moulds whose weight varies between 50 and 1,500 kg necessitates taking numerous precautions, the toolmakers frequently had their work interrupted while awaiting the availability of the jib crane. It was therefore decided to make each station autonomous with its own crane fitted with two VERLINDE hoists of a lifting capacity of 1.6 tonnes. The three EUROPONT cranes travel on the same metallic structure and to avoid accidental collisions, limit switches guarantee travel safety.
Following this new work organization making each work station autonomous, the productivity of the mould routine maintenance shop has risen by 25%. As moulds are made of two parts whose sizes and weights vary, each crane is fitted with two VERLINDE EUROCHAIN VR Vario hoists in order to facilitate their manipulation in complete safety.
The selected VERLINDE EUROCHAIN VR Vario hoists are fitted with 2-speed motors for lifting and a variable speed motor for horizontal travel. In this way the load is totally controlled horizontally and vertically without any rocking effect. The daisy-chain type power supply is conventional and the control boxes are wired. This solution was in fact preferred to a wireless system for reasons of safety, in order to avoid any possible confusion between the control boxes of the three work stations

Chain hoist targets less experienced operators

Tuesday, August 18th, 2015

VARIO is the inverter version of VERLINDE’s EUROCHAIN VR electric chain hoist. Designed for handling loads of 100 to 2500kg, operator productivity is enhanced, life span increased and operating flexibility is improved.

The VVF drive has no lifting movement thresholds, which enables accurate positioning of loads and greater operating flexibility. Depending on the value of the load, the type of movement and their own experience, the operator can choose the travel speed most appropriate to the operation. Lifting operations are safer and more accurate. With its minimum speed of approximately 0.25m/m, VARIO enables less experienced operators to manipulate loads with no risk of damage. Continuous control of speed also provides greater productivity. This feature now allows lift speed and motor torque to be dissociated: speed, for the reduction of cycle time to enhance hoist station productivity when running empty, and motor torque, for lifting under load to ensure precision travel with a maximum power margin.

The VARIO inverter system called ESR provides a maximum speed 1.5 times greater than the standard speed, and the integrated customised version of the deceleration ramp enables a lifting speed twice as fast as normal with light loads. Full speed can be used to a maximum of 40% of the rated load, the maximum motor speed remaining at 3000rpm. At 20% of the load, the rated speed is the equivalent of 150% of the listed speed. With nominal load, the rated speed is the equivalent of the listed speed.

With VARIO the life span of equipment is increased. Continuous speed control reduces mechanical shock by means of gradual starts and smoother halts. The reduction in the number and level of shocks to which the crane components or structure are subjected increases the life span of the frame. Continuous speed control, furthermore, enables the use of the electric brake during deceleration before application of the mechanical brake. Electrical braking reduces brake wear because the mechanical brake is only used when stationery.

VARIO has all the advantages of EUROCHAIN VR electric chain hoists..
