Description

 The invention relates to industrial transport, in particular to vertical conveyors for piece cargo.

 Known vertical chain conveyor for piece goods (French patent N 2123099, class B 65 G 17/00, 1972), including a frame, drive, tension and deflecting sprockets, covered by two pairs of traction chains, to which are attached load-bearing platforms having loop sections .

 However, this conveyor requires sophisticated technical equipment for loading and unloading operations in loop sections.

 Also known is a vertical system for piece cargoes selected as a prototype (ed. St. USSR N 1244046, class B 65 G 17/48, 1986), including a frame, drive, tension and disconnecting sprockets that envelope their two pairs of traction chains, which installed load-bearing platforms, having loopback horizontal discharge sections.

 The disadvantages of this conveyor system are: the complexity of the design of load-bearing platforms and devices for supplying and receiving cargo, as well as the complexity and unreliability of the mechanism for driving the platform deck.

 The aim of the invention is to simplify the design, increase reliability.

 This goal is achieved by the fact that in the proposed conveyor system, including drive, tension, deflecting and bypass sprockets, enveloping sprockets are two pairs of traction chains with loop unloading sections and mounted on traction chains of load-bearing platforms of one-sided flexibility, loop unloading sections are made movable in vertical planes with the possibility of fixation in horizontal and inclined positions, and the surface of the load-bearing platforms is made with the possibility of sliding the load from them in sloping position of the loopback unloading sites. The surface of the load-bearing platforms is made with a low friction coating (for example fluoroplastic) or in the form of rollers.

 Compared to the prototype, the distinguishing features are novel. Within the scope of the patent search, this combination of distinctive features was not found, on the basis of which we can conclude that the invention has the criterion of "Significant differences". Figure 1 shows the proposed conveyor system, General view; figure 2 view a in figure 1; figure 3 view B in figure 1; figure 4 conveyor system, a General view according to claim 3.

 The vertical conveyor system includes a frame (not shown), drive 1, tension 2, deflecting 3 and bypass 4 sprockets, enveloping them with two pairs of traction chains 5 with load-bearing platforms 6 of one-sided flexibility fixed to them, a loop unloading section with bypass sprockets 4, receiving roller conveyor 7. The loopback unloading section is equipped with a lifting and lowering mechanism, including a hydraulic or pneumatic cylinder 8, a U-shaped rod 9 and levers 10. The lifting and lowering mechanism serves to tilt the discharge section at the right time ka conveyor system, which ensures the sliding of the load 11 from the platform 6, having a low friction coating (eg fluoroplastic) or rollers 12, to the receiving roller conveyor 7.

 Vertical conveyor system operates as follows.

 After loading, the platforms 6 move along the trajectory of movement by the traction chains 5. During the passage of the platforms 6 of the lower part of the unloading loop section equipped with a lifting and lowering mechanism, if necessary, the bypass stars are lowered 4. Platform 6 with a low friction or roller coating moves in an inclined plane , which ensures the sliding or rolling of the transported cargo 11 to the receiving roller conveyor 7 or the tray. After passing the loop discharge section and unloading on it in the case of lowered by-pass sprockets 4, the empty platform 6 continues to move. When the bypass sprockets 4 are in the raised position, unloading does not occur, then platform 6 delivers cargo 11 to the next floor. The lifting and lowering mechanism may also have an electromechanical drive.

 The advantage of the proposed conveyor system, in comparison with the prototype, is a simplified design and increased reliability. The use of the claimed technical solution simplifies the unloading process, which allows for automatic, multi-position unloading in the presence of intensive cargo flows of piece goods, including irregular shapes, for example, bags distributed between several floors of a production or other building.
