CHAIN CONVEYOR

CHAIN CONVEYOR

The chain conveyor is intended for the horizontal transportation of bulk materials such as cereal grains, oil and legume seeds, raw materials for the production of feed, biomasses, ash and dust.

The devices presented below are used in industries such as:
woodworking, port, feed, cereal storage facilities, milling, oil extractor presses.


 

Chain conveyors are assembled from ready-made modules:
drive station, inner segments, tension station and chain. This allows the assembling of chain conveyors with lengths of up to 85 m.

The bottom and the top deck of conveyors are lined with anti-static abrasion- resistant PE1000 or PUGA material. The lining thickness is selected according to the conveyor capacity and the type of material being conveyed, but the minimum thickness we use is 10 mm.

As standard, our conveyors are made of Z275 galvanised steel sheet, but optionally they can also be made of S235 steel, powder-coated in RAL colours, or of acid-resistant steels such as AISI 304, AISI 316 and HARDOX.

INNER SEGMENTS

Inner segments are available in versions:

  • Standard - chain return on rollers or centre slides or V-shaped slides.
  • Self-cleaning - chain return after intermediate bottom.
  • Bi-directional - lower and upper deck with the same capacity.

Tensioning stations are available in versions: 

  • Standard - chain return after the roll.
  • Bi-directional - lower and upper deck with the same capacity.
CHAIN
CHAIN

Chain type V-TS-R All chain elements manufactured by our company are made on numerically controlled machine tools, which ensures the highest quality and repeatability of the links. Thanks to the special V-shaped chain design, we have an advantage over the competition, guaranteeing that the chain cannot come undone during operation and 2 times higher breaking forces than standard chains used in conveyors of the same performance. Components such as pins and bushings are subjected to a special thermo-chemical treatment to ensure the highest quality and long-term trouble-free operation.

STANDARD ELECTRICAL EQUIPMENT

Our standard is to equip conveyors with electrical sensors, ensuring the highest health and safety standards, and reliable operation. The sensors used indicate incorrect chain tension, conveyor overflow, opening of inspection flaps.

  • RPM sensor - chain tension
  • Conveyor overfill sensor
  • Flap opening sensor
  • Turck or IFM inductive sensor
  • Pizzato Elettrica key switch FR-692-D1
STANDARD CONSTRUCTION OF RYBINSKI CHAIN CONVEYORS
  • The chain conveyor structure is manufactured using CNC laser cutting, CNC press brake forming and eccentric presses.
  • Plastics used:
    • hard-wearing antistatic,
    • temperature-resistant,
    • intended for the food industry.
  • Chain support rollers:
    • Roller axle made of S355 steel by CNC turning,
    • Roll sheath bearing and sealed, made of plastic, CNC turning method

 

  • Segment linking system:
    The conveyor segments are joined using special connectors made from steel by CNC cutting, which are then subjected to plastic processing on press brakes and eccentric presses. Specially punched connection holes in the sides of the conveyor segments and in the connectors, together with the connection with ISO 10642 taper screws, guarantee straightness over the entire length of the conveyor (even in lengths of up to 80 mb). Thanks to this system of connecting segments, the conveyors are characterised by very high rigidity and stability. As standard, the support or suspension of the conveyor is required every 6 m.

DRIVE STATION

 

  • flashings made by CNC laser cutting, plasticised on CNC press brakes and eccentric presses,
  • drive wheel - sprocket made of S355 or C45 steel by CNC milling from one fastening, mounted on the drive shaft with a prismatic key,
  • drive shaft mounted outside the conveyor housing in bearing units from renowned manufacturers: SKF, SNR, KOYO,
  • elimination arch
  • inspection hatch with a key switch,
  • overfill flap with induction sensor

 

DRIVE STATION DRIVE STATION DRIVE STATION
TENSIONING STATION
  • flashings made by CNC laser cutting, plasticised on CNC press brakes and eccentric presses,
  • reversing wheel - smooth tensioning wheel made of S355 or C45 steel by CNC turning from one fastening,
  • tension shaft - mounted outside the conveyor housing in bearing units from renowned manufacturers: SKF, SNR, KOYO,
  • tensioner sealed - equipped with a double-sided ruler allowing for precise and correct chain tension,
  • tensioner mechanism - based on M30 bolts in class 8.8, enables smooth sliding of the tensioner plates front-back,
  • elimination arch - the dead zone is permanently connected to the tensioner plates, thanks to which the distance between the tension wheel and the arch eliminating the dead zone is constant at each position of the tensioner,
  • turck or IFM rotation / slack chain sensor,
  • between the tensioner plates and the side sheeting of the tensioning station, antistatic, hard-abrasive PE-1000 material is used to eliminate metal-to-metal friction

 

RYBINSKI CHAINS FOR STANDARD CHAIN CONVEYORS

Chains type V-TS-R produced by our company are characterized by high reliability and failure-free operation.

We have been manufacturing this type of chain continuously for over 30 years with due diligence, controlling the production process at every stage. Thanks to the use of CNC machines, we are able to provide the highest quality standards. That's why our chains average 7,500,000 tons of grain over their lifetime.

We obtain the highest quality thanks to the use of certified materials and special thermal and chemical treatment to which the pins and bushings of our chains are subjected.

Highlights:

  • The single-link construction of the chain ensures smooth operation on the bottom, rollers and guides.
  • Can be shortened every link.
  • The links are made of S355 steel.
  • Sleeves made of E235+N steel are subjected to a special thermo-chemical treatment.
  • Pins made of 42CrMo4 steel are subjected to a special thermo-chemical treatment.
  • Coupling system: external sleeve + cotter pin made of patented wire, class B, allows for 100% protection against unfastening during chain operation. Quality control at every stage of production
