ALLMÄNT

Palletter transporterade i ett system drivet av P&F kedja göra det möjligt att skapa ett flexibelt pallet system.

Man kan uppnå en snabb, precis, pålitlig, tyst transport av palletter till en samling arbetsstationer.
Följande fördelar, som i stort är desamma som för hängtransportörer av P&F typ, är:

  • Kallning av önskat gods till önskad arbetsstation, med möjlighet till olika takt på olika arbetsstationer.
  • Möjlighet till buffertar var som helst i anläggingen.
  • Möjlighet att dubbla hastigheten i vissa delar av anläggningen.
  • Möjlighet att åstadkomma extremt precisa stopp av palletten vid arbetsstationen.
  • Möjlighet till sortering av gods efter många olika variabler.
  • Möjlighet till växling av gods.
  • Möjlighet till 90 graders ändring av transportriktningen vid tranportörskifte.
  • Möjlighet att låta gods som inte kan tas emot på arbetsstationen återcirkulera.
 

PLUS
High compactness of the line lay-out and therefore of the covered area.
High components modularity and standardisation allowing the line assembly/disassembly with a limited number of tools and to carry out the line pre-assembly with modules size compatible with transport requirements.
Anodised surface scratch and corrosion resistant which does not need any manitenance.
The accessories are easy and quickly fit in any point of the profile thanks to longitudinal slots on the profile itself.
Chain low noise level. 		 
 
SYSTEM 08: trasponder reader   Possibility to use a special chain able to double the pallet speed compared to the chain one and therefore able reduce transport times without increasing the noise level.
Millimeter tolerances in the pallet stop in the working area thanks to the use of peculiar positioning devices.

Optimisation of the number of needed motors, thanks to the possibility for each straight line to have its own motor or a motor common to other lines.

Possibility to integrate the line with lifting and lowering devices to carry out level changes as well as to have workstations with height changes and manual or powered rotations to facilitate the operations they have to undergo.

  SYSTEM 08: transfer unit
Creation of in line or out of line workstations, custom-tailored according to each ccustomer's requirements, using a wide range of CONVEYORS accessories.

KONTSTRUKTIONSDETALJER

 

Transfer system with power and free conveyor chain consists of a modular structure made up of two parallel tracks in which low friction coefficient chain guides have been fixed. The chain runs above the upper guide and the loads are placed on it, moving on proper bases, made of metal or phenolic or epoxy resins, called assembly pallets.

Tracks for chain sliding are made of two extruded anodised aluminiun splined sections for the accessory fitting. Laterally there are guides to centre pallets.

The return chains run inside the extruded aluminum section, completely protected.

The chain are made of carbon steel or stainless steel AISI 304. There are two different types of chain: for transport and buffer or for transport only (lines without buffers).

Chains that transfer loads are driven by driving heads. They are made of die cast aluminium and have the gear motor directly connected to the motor shaft on which are assembled driving wheels.

  Drive unit
Stop stations are devices allowing the pallet stop on buffer lines or transfer lines where positioning devices are installed.

Stop station		  

Stations, fixed through an aluminium spacer to the two paraller tracks in a central position compared to these last, are made of a pneumatic cylinder with integrated guides and steel or polyethilene stop ledge.
Double stops are used in case one pallet at a time had to be forwarded to the buffer.

Pallets locking devices are installed in the areas where a higher transported product stability is required or where assembly operations require thrust that would move the pallet in undesired positions.

These devices are assembled also in positions where a centring is needed to allow auxiliary equipment to intervene on the pallet or the product transported by it.Transfer systems with power and free conveyor chain "System 08" can be equipped with special devices such as transferts, turn tables, lifters and drop sections.

TEKNISK HUVUDSPECIFIKATION

Payload up to 600 daN.
Possibility to use pallet having a minimum width of 260 mm up to 1000/1500 mm.
Transfer speed up to 60 m/min (in which case the pallets must be made in such a way that they have a high chain-friction coefficient).
Driving heads can differ in power, speed, chain type, working method (with continuous motion or step-by-step).
The size of the extruded profile depend on the transported product size and weight and on the type of chain employed.
A series of service profiles are available for the electric and pneumatic wiring as well as stardardised particular components to facilitate the various components assembly.
