Abstract

A device having a variable-capacity store (3) formed with the aid of conveyors on two neighboring levels having one input channel (1), formed by a lower conveyor (4) and an upper conveyor (5), and one output channel (2), formed by an upper conveyor (6) and a lower conveyor (7), having a back plate (12), which is coupled with a slide (16) separating the levels of the store (3), equipped with a separating conveyor (17) so that they jointly effect to and fro motion, parallel to the horizontal conveyors, with the surface of the back plate (12), concave on the side of the store (3), is formed a the chain conveyor (13), characterized by the fact that the upper input conveyor (5) has at the end an arched part (8) pointing upwards, and the lower output conveyor (7) has at the beginning an arched part (9) pointing downwards, so that the two conveyors (5 and 7) approach each other with the arched parts (8 and 9), and between the arched part (8) of the upper input conveyor (5) and the arched part (9) of the lower output conveyor (7) there is an in-between swing element (10), and a slide (16) with a separating conveyor (17) is slipped between the arched part (8) of the upper input conveyor (5) and the arched part (9) of the lower output conveyor (7), after deflecting the in-between swing element (10). Prior to slipping the slide (16) with the separating conveyor (17) the in-between swing element (10) makes the front plate (11) for the rod shaped elements displaced from the input channel (1) to the output channel (2) the distance between the axis of a return roller (18) of the separating conveyor (17) and the back plate (12) of the store (3) is constant and equal to the radius (r) of the back plate (12), while at minimum capacity of the store (3) the back plate (12) is located at the distance (w) from the front plate (11) corresponding to the width of the input channel (1) and the output channel (2).

Claims

1. A store-transport device for elongated rod shaped elements, disposed in a transfer line for elements from a delivery device to a receiving device, having a plurality of substantially horizontal, vertical and arched conveyors, and having a variable capacity store formed with the aid of the said conveyors on two neighboring levels, having one inlet and one outlet, formed by two parallel conveyors, closed with a joint back plate which is coupled with a slide separating the store levels, equipped with a separating conveyor, so that they together perform reciprocating movements parallel to the horizontal conveyors, and its concave surface, on the store side, is constituted by a chain conveyor equipped with transverse humps, and a fullness sensor is placed near the outlet, characterized in that an upper input conveyor (5) has at the end an arched part (8) pointing upwards, and a lower output conveyor (7) has at the beginning an arched part (9) pointing downwards, so that the two conveyors (5 and 7) approach each other with the arched parts (8 and 9), but between the arched part (8) of the upper input conveyor (5) and the arched part (9) of the lower output conveyor (7) there is an in-between swing element (10), and a moving slide (16) with a separating conveyor (17) is slipped between the arched part (8) of the upper input conveyor (5) and the arched part (9) of the lower output conveyor (7), after deflecting the in-between swing element (10).

2. A device as in claim 1, characterized in that the in-between swing element (10) consists of a lower in-between swing element (101) mounted at the end of the arched part (8) of the upper input conveyor (5) and an upper in-between swing element (102) mounted at the end of the arched part (9) of the lower output conveyor (7).

3. A device as in claim 2, characterized in that the in-between swing element (101) has the form of a lower in-between conveyor (101′

), and the upper in-between swing element (102) has the form of an upper in-between conveyor (102′

).

4. A device as in claim 3, characterized in that the lower in-between conveyor (101′

) is driven by the upper input conveyor (5).

5. A device as in claim 4, characterized in that the upper in-between conveyor (102′

) is driven by the lower output conveyor (7).

6. A device as in claim 2, characterized in that the horizontal separating conveyor (17) is slipped between the lower in-between swing element (101) and the upper in-between swing element (102), after drawing them apart.

7. A device as in claim 6, characterized in that the lower in-between swing element (101) is deflected downwards when slipping the separating conveyor (17) in.

8. A device as in claim 6, characterized in that the upper in-between swing element (102) is deflected upwards when slipping the separating conveyor (17) in.

9. A device as in claim 1, characterized in that prior to slipping in the slide (16) with the separating conveyor (17), the in-between swing element (10) or the in-between lower (101) and upper (102) swing element constitute the front plate (11) for the rod shaped elements displaced from the input channel (1) to the output channel (2).

10. A device as in claim 1, characterized in that the distance between the axis of a return roller (18) of the separating conveyor (17) and a back plate (12) of the store (3) is constant and equal to the radius (r) of the back plate (12).

11. A device as in claim 1, characterized in that for a minimum capacity of the store (3), the back plate (12) is located at the distance (w) from the front plate (11), corresponding to the width of the input channel (1) and the output channel (2).

12. A device as in claim 4, characterized in that the individual moving sub-assemblies or groups of moving sub-assemblies are independently driven by separate motors.

13. A device as in claim 3, characterized in that the horizontal separating conveyor (17) is slipped between the lower in-between swing element (101) and the upper in-between swing element (102), after drawing them apart.

14. A device as in claim 2, characterized in that prior to slipping in the slide (16) with the separating conveyor (17), the in-between swing element (10) or the in-between lower (101) and upper (102) swing element constitute the front plate (11) for the rod shaped elements displaced from the input channel (1) to the output channel (2).
