Description

Cooling bed with several run-up channels When rolling several at the same time Veins in several run-up channels of a cooling bed, it is of great importance that the roll bars individually, d. H. separately from each other. This will be today Achieved by conveyor chains, which the bars individually from the run-up chutes vertically promote upwards, or by the fact that the rods by special design of the slip surfaces or transfer devices separated from each other in different notches of the Cooling grate or the conveyor rake are placed and that the transverse stroke of the conveyor rake a multiple of the calculation notch distance corresponding to the number of rods. In this way, one achieves that the rolled bars deposited individually in the notches of the conveyor grate bars be conveyed over the entire cooling bed surface without contact with other rods. In the first case, the gutters cut through in the vertical direction Noticeable disturbing conveyor chains; in the latter case, the conveyor rake must be very describe large eccentric stroke, regardless of whether the associated run-up channel is occupied at all, d. H. dropped a stick or not. In this way is only part of the notches in the conveyor grate during operation with bars occupied and so the cooling bed area is not fully used. To cool down enough To achieve, therefore, the width of the entire cooling bed must be unnecessarily large, what requires a larger space requirement and expensive systems. .

The purpose of the present invention is that the bars individually over the conveyor grate be conveyed, the conveyor rake describing a transverse stroke that is only the same is the distance between two adjacent arithmetic notches, where the condition is met is that all computing peaks are covered with rolling rods and so a complete Utilization of the cooling bed is achieved. The conveyor rake makes after each drop a transverse stroke. It is important that not several bars at the same time or directly one after the other from different drainage channels into the same calculation notches be filed. This is prevented by influencing the ejection or transfer devices from the gutters to the rake bed, as it is similar known for multi-core cooling beds and promotion of the rods above the run-up channels is. In connection with the analogous initiation of movement of the cross conveyor path the computing system automatically creates an orderly sequence of the desired movement processes, which cause a complete utilization of the cooling bed in a trouble-free manner.

In the drawing, three exemplary embodiments of the device are shown.

Fig. I shows a two-lane roller table of known design. I and 2 represent the two gutters and 3 and q. the associated lifting slide . From channel 2, the rod 5 is ejected, which almost simultaneously from channel i ejected steel6 is held in place by the flap 9 until the rod 5 has reached the notch 7 and from there by a movable rake in the notch 8 was laid. After these movements have been made, it opens Flap 9, and the rod 6 falls into notch 7. Then the moveable one leads Immediately calculate a stroke so that the notch 7 can be used to accommodate another Rod aui, channel 2 is free. The delay in the $, extraction after calculation notch 7 occurs dG @ ch @ mechanical or electrical influencing of the lifting or holding devices, so that the rods are placed individually in the computing notches and also transported on the cooling bed will.

Fig. 2 shows a roller table and three run-up channels, which are designated with io, 11, 12. Here the moment is shown in which the rod 13 slides from groove io into notch 14; The rod 1 5 , which is located in channel ii on the way to the rake bed at the same time, is held back in the position shown - by delaying the slide movement by putting the moving power source out of operation through the slide position of channel io until rod 13 comes out of notch 14 was placed in notch 16. The slide in channel 12 is accordingly influenced by both slide positions of the two other channels. The lifting devices can change the speed or be brought to a complete standstill by the described influencing, the mode of operation of which will be explained in more detail in an exemplary embodiment. It is essential that this control system brings the bars individually into separate conveying rake notches in the cooling bed. The transverse conveying means can also have straight rakes according to Fig. 2a, or instead of a rake cooling bed, for example, other conveying means, such as inclined rollers or the like, can be used.

Fig. 3 shows another type of three-channel cooling bed. Here a special conveyor 17 lifts the bars i8, ig, 2o from the collecting pockets next to the rake bed 21. The latter makes three strokes one after the other, with the conveyor 17 taking positions a, b, c one after the other, so that the bars are lifted individually and on over the cooling bed can be transported.

An embodiment for. working greed carrion lifters is shown in Figure 4.

It means I, 11. III the partitions of a three-channel roller table of a cooling bed. The lifting devices for the roll bars are shown with d, e, f . a, a1, a2 mean separating devices that cut the rod in motion and belong to the three gutters named gate. The device is such that only one rod can fall into the rake i at a time, the rods can run quite arbitrarily into the three '"gutters. This is achieved in the embodiment by a simple electrical circuit. After the motor a after cutting off a rod has switched on the motor b and thus set the lifting slide c in motion via the eccentric and linkage, the latter has meanwhile reached its upper end position, so that the roller rod k is about to slip into the rake i. Here the slide c switches through a Time switch d the other two slides e and f, which should be in the upward movement, for a desired time half the circumference of the crank, ie during the upward movement, at the same time the motor switches through the Endsc holder g his own motor b1, b2 off again. The counterweight h pushes. the slide c (e, f) back into its end position so that it is ready for the transport of the following rod on this path. This movement process is analogous for all lift-out slides. The purpose is thus achieved that only one rod can fall onto the groove of the computing system i at a time, because the slide, which is in the upward movement, switches off the other two slide at its upper end. This can be achieved in a similar way by means of a mechanical influence.

Claims (1)

PATENT CLAIM: Cooling bed with several run-up channels from which or from their collecting pockets the individual rolling rods to the intermittently working cooling bed cross conveyors supplied directly and individually while maintaining a corresponding distance are conveyed further from each other, characterized in that the delivery stroke of the Cross conveyor only about the same as the distance between two adjacent ones deposited on it Roll bars is and that the lifting means of the individual run-up channels in mutual Dependency can be controlled so that the transfer of the rolling rods to the cross conveyor takes place one after the other at time intervals by adding each conveying stroke of the cross conveyor only one rolling rod is passed.
