Abstract

 An on line bar collecting movable open channel with transverse discharging means on transverse transfer bed particularly in hot rolling plants, characterized by the fact that it includes:
- in a tilted bar sliding plane (4), at least two reciprocate channel seats having at least one open channel each one, laterally opened in "C" shape with tilted basis (1) opened toward a beam of a transverse bar transfer bed (3), said sectors reciprocating inside guiding walls (2) in said tilted plane (4), being (3) said (1) sectors (2) sliding in outside position over said tilted plane and retractable under said tilted plane (4), allowing each bar (b) to slide toward said transverse transfer bed plaque (3);
- in order that at lowering of said channels (1), bar receiving channels (b) are closed by a lateral wall of the respective wall guides (2) whereas in upper outside position over said tilted plane (4), said bars (b) will slide down on said tilted plane (4) toward the adjacent subjacent transverse transfer bed (3).

Description

[0001] The present invention has for object an on line bar collecting movable open channels with transverse discharging means on transverse transfer plaque bed particularly in hot rolling plants. The innovation finds particular even if not exclusive application downwards the hot rollingmills in rolling plants to receive and to stop the longitudinally advancing bars after cutting in length and deviation by means of shunter on parallel ways (channels) to allow successive discharging on a respective cooling transverse transfer plaque bed.

[0002] In Prior Art, different on line bar collecting movable channels with transverse discharging means on transverse transfer plaque bed particularly in hot rolling plants, are well known. This devices are complicated and expensive, present a high wear grade and have speed limits for notable masses in movement, such plants involving in particular consistent masses displacement. In many cases the entire structures of the channels is moved e.g. rotary channels or oscillating channels, while in other cases the bar extraction means from fixed channel are complex and easily tangled.

[0003] Purpose of the present invention is to obviate the above-mentioned drawbacks.

[0004] This and other purposes are reached with the present innovation as claimed solving the exposed problems by means of an on line bar collecting movable open channels with transverse discharging means on transverse transfer bed particularly in hot rolling plants, characterized by the fact that it includes:
- in a tilted bar sliding plane, at least two reciprocate channel seats having at least one open channel each one, laterally opened in "C" shape with tilted basis opened toward a plaque of bar transverse transfer bed plaque, said sectors reciprocating inside guiding walls in said tilted plane, being said sectors upper sliding in outside position over said tilted plane and effaceable under said tilted plane, allowing each bar to slide toward said transverse transfer bed plaque;
- in order that at lowering of said channels, bar receiving closed channels through a lateral wall of the respective wall guides are realized whereas in upper outside position over said tilted plane, said bars will slide down on said tiled plane toward the adjacent underlying transverse transfer bed plaque.
In such way:
- the masses in movement are reduced;
- the extraction mechanism results substantially simplified and more reliable.

[0005] These and other advantages will appear from the successive specification exposing a specified preferential solutions of realization with the help of the accompanying drawings which particulars of execution are not to be considered limitative but exemplificative only.

Figure 1 represents a diagrammatic view in transverse section of a device as per the present invention with two channels for each reciprocable channel seat.

Figure 2 represents a diagrammatic view in transverse section of a device as per the invention with one channel for each channel seat.

[0006] Making reference to the figures is appreciated that that the bar collecting and transfer device regards an on line bar collecting movable open channels with transverse discharging means on transverse transfer bed particularly in hot rolling plants, the device including:
- in a tilted bar sliding plane (4), at least two reciprocate channel seats having at least one open channel each one, laterally opened in "C" shape with tilted basis (1) opened toward a plaque of bar transverse transfer bed plaque (3), said sectors reciprocating inside guiding walls (2) in said tilted plane (4), being said sectors upper sliding in outside position over said tilted plane and effaceable under said tilted plane (4), allowing each bar (b) to slide toward said transverse transfer bed plaque (3);
- in order that at lowering of said channels (1), bar receiving closed channels (b) through a lateral wall of the respective wall guides (2) are realized whereas in upper outside position over said tilted plane (4), said bars (b) will slide down on said tiled plane (4) toward the adjacent underlying transverse transfer bed plaque (3).

[0007] Advantageously the channel seats (1) reciprocates in guide walls (2) and their reciprocation is realized by stems (1′) associated with oscillating arms (1˝).

[0008] Of course the number of the channels and the number of the channel seat bodies (1) can be more than two and the channels advantageously can be even of different size to allow receiving bars of different diameter.
