Abstract
Conveyor device (1) including an endless conveyor belt (4), a first drive (3) for driving the endless conveyor belt (4), a main frame (2) and an auxiliary frame (19) supported in the main frame (2), a second drive (15) for moving the auxiliary frame (19) back and forth relative to the main frame (2) in the manner of a shuttle-conveyor, such that a supply track (4a) of endless conveyor belt (4) supported by the auxiliary frame (19) can feed products (P) on a discharge track (4b) of endless conveyor belt (4) supported by the main frame (2).
Claims20
A conveyor device, comprising:
- a main frame;
- an endless conveyor belt supported by the main frame, the conveyor having an inlet end and a discharge end;
- a plurality of circulation rollers defining a path of circulation of the conveyor belt, the circulation rollers including a first circulation roller forming an upstream first end roller at the inlet end, and a second circulation roller forming a downstream second end roller at the discharge end;
- a first drive for driving the conveyor belt around the circulation rollers, for conveying products in a first direction;
- a discharge track ending at the location of the second end roller;
- an auxiliary frame supported in the main frame, the second end roller and a third circulation roller arranged on said auxiliary frame;
- and
- a second drive for moving the auxiliary frame back and forth relative to the main frame in the first direction and a second direction opposite the first direction, in the manner of a shuttle conveyor, the shuttle conveyor being retractable at a relatively high speed for releasing the products situated on the discharge track from the conveyor belt due to inertia and permitting the products to drop down with gravity,
- wherein the conveyor belt forms an open loop in the auxiliary frame, a shape of said open loop being defined by the second end roller and the third circulation roller, as well as by fourth and fifth circulation rollers arranged in the main frame above a line connecting bottom sides of the second end roller and the third circulation roller to one another, and situated stationary relative to the auxiliary frame, for circulation of the inbound part and the outbound part, respectively, of said open loop.

A conveyor device, comprising:
- a main frame;
- a supply device supported by the main frame and including a supply track having a supply belt conveyor for conveying products from an inlet at which location a first end roller for the belt conveyor is situated;
- a discharge device supported by the main frame including a discharge track having a discharge belt conveyor for discharging products at the discharge end, at which location a second end roller for the discharge belt conveyor is situated,
- the discharge device including an auxiliary frame, which in a displacement path can be moved back and forth relative to the main frame in the manner of a shuttle conveyors in a relatively high speed returning motion for discharging the products in a downward direction,
- the supply belt conveyor and the discharge belt conveyor configured with a same endless conveyor belt circulating around a plurality of circulation rollers, and moving through the supply track and the discharge track;
- a first drive for driving the endless conveyor belt in a circulating manner;
- and
- a second drive for moving the auxiliary frame back and forth,
- wherein the supply track ends at the location of a circulation roller forming a third end roller, which third end roller is situated above the discharge track,
- wherein the conveyor belt forms two loops, which at the location of transitions connect to each other, merge into each other, with an open loop on the auxiliary frame that can be moved back and forth and an open loop in the relatively stationary main frame, and
- wherein the third end roller when considered in conveyance direction extends over the locations of transition and can be moved to a maintenance position in which those locations of transition are accessible.
