Precision Conveyors
ITALPLANT precision link conveyors are the state-of-the art of conveyors for every kind of industry: mechanical, manufacturing, assembling, packaging, and every genre of applications: medical, cosmetic, electronic, and so on. ITALPLANT precision link conveyors combine excellent accuracy, high speed, smooth movement, high load capacity, versatility of positioning, custom length.
Driven by an ITALPLANT rotary indexer with globoidal cam, able to guarantee a motion given by an incredible variety of motion laws (MS, MS20, MT, CYC, etc.), both standard than personal, customer have the maximum degree of reliability.

STEP 1: CHOOSE YOUR CONVEYOR BY ACCURACY
Each link of ITALPLANT conveyor shows an accuracy value that can be measured along the three directions of length, width, height (X,Y,Z). All measurements will be taken at the fixture locating dowel pin and inspected one link in from the take up end. The “Y” (side to side accuracy) and “Z” (vertical accuracy) tolerance value will be remain the same at any given station along the entire length of the conveyor. The “X” direction tolerance value will be greatest at the link farthest from the drive sprocket and will improve with closer proximity to the sprocket (index accuracy).
STEP 2: CHOOSE THE MOUNTING POSITION
Carousel conveyors show the links on right and left side. For this peculiarity that gives the possibility to work on both sides, it is possible to use for the stations the total length of the conveyor. This type of conveyor does not permit, anyway, to load directly on links but only by fixtures mounted laterally on itself to carry a load that rollers could bear: indispensable then to calculate every time the overturning torque on links and fixtures that are generally out of centre.
Over-Under conveyors are imagined to work usually on the upper side, on the open view, but in comparison to the preceding ones are more suitable to be carried by a pick and place or robots, and they are able to bear loads or external forces directly on the links. Otherwise, with the same number of fixtures, you have to provide a double length than Carousel.
STEP 3: CHOOSE THE MOTORIZATION
PRECISION BELT CONVEYOR (PBC)
It’s almost an all-aluminum structure, that combines two basic concepts for the customer: modular structure according to the customers needs and hugely lower costs, compared to other transport belt systems.
This has been possible by a combination of design essential and rigid mechanical linkages: the result is a conveyor suitable for many applications at higher level than its competitors belt, and yet much cheaper.
The motorizations applicable may provide an intermittent motion – Italplant rotary tables or HER/servo motor with an own motion law – or
continuous – HER/servo motor.
See this assembly drawing for ‘XYZ’ direction clarification.
All ‘XYZ’ accuracy measurements will be taken at the fixture locating dowel pin and inspected at the location indicated on the assembly drawings.
The ‘Y’ and ‘Z’ accuracy tolerance will remain the same at any given station along the entire length of the conveyor.
The ‘X’ direction tolerance value will be greatest at the links farthest from the drive sprocket an will improve with closer proximity to the sprocket.
ITALPLANT cannot put an exact value on this accuracy improvement and will only guarantee with the following values. These assuracy values relate to any given station not as one station relates to another. ITALPLANT will mantain an inspection report on this unit as well as supply the customer with a copy.
Accuracy values by link size
‘X’ accuracy 1m length: +/- 0.18mm
‘Y’ accuracy (at any link): +/- 0.18mm
‘Z’ accuracy (at any link): +/- 0.18mm
All accuracy tolerances are plus and minus.
Length deviation
Due to the diametrical clearance requirement between the link pin and needle bearings, the overall length of the conveyor will deviate.
This deviation is dependent upon the number of links between the drive sprocket and takeup end and is progressive, starting at the drive end.
The maximum deviation from theoretical perfect station centre will be at the link farthest from the drive sprocket.
This deviation does not affect the ‘XYZ’ accuracy of links as measured at any given station once the actual center has been established.
To compensate for this deviation, ITALPLANT recommends all station tooling be slotted to provide for adjustment at setup.
Maximum deviation
For the link the deviation will be +/-0.018 for link.
In all cases the deviation will be to the plus side.
Available link sizes
60 mm – 80 mm – 100 mm – 160 mm

PRECISION LINKS AND FOLLOWERS
Each link of an ITALPLANT precision link conveyor is machined with high accuracy as standard. Links are made by anodized aluminium, but it is also possible for steel or other materials on customer’s demand. Each link features on the upper face standard tapped holes and dowels seats for fixing (see following drawings) but it is also easy to get custom holes.
Each link mounts hardened rollers, checked one by one and greased for life.
The link has four rollers on the two sides, and two in the lower face for guidance.
In house assembly ensures the total absence of lateral and axial backlash, given by a pre-load of the chain to the lateral guides. Rollers pins are mounted on needle bearings, while central rollers are secured with bolts.
All ITALPLANT precision link conveyors (or carriers) mount hardened dual drive sprockets able to guarantee a transmission without backlash between the drive unit and chain links. On the opposite side, a special tensioning cam designed by our technical office maintains a precise tension of the chain.
Tracks where rollers run are hardened and ground and are a high precision components.
The majority of precision link conveyors produced by ITALPLANT include custom alterations. Conveyor length, index distance, index motion, working position – horizontal or vertical – link fixture mounting pattern, link material, tooling plate configuration, line shaft configuration, support base design, drive package components and drive package arrangement
Even if all these options are not enough, ITALPLANT can supply complete special conveyors following customers’ suggestions.
The design of ITALPLANT precision link conveyors is founded on three different entities: drive head (including pinion, input shaft, motorization), take-up end (including cam and all tensioning system) and the generic module, with which we indicate one link and all the structures that supports it, beam and tracks. With these three entities, it is possible to assemble the required length simply pointing out the number of links, obtained by:
number of stations (*) x link pitch
Length, showed in inches or mm depending of versions, indicates in this way the distance between drive end axis and take up end.
