Solidification is accelerated by cooling the bottom of the basin.

When the bitumen is sufficiently solid, it is cut into pieces by an automatic apparatus according to the invention, the apparatus comprising a machine arranged to be mechanically moved intermittently on wheels, at least one of which is motor driven, the length of the movement corresponding to the length of the bitumen body. The cutting into pieces is performed to suitable dimensions to give the pieces the desired weight.

The pieces then proceed to a known packaging machine connected to a cutting machine, where they are packed in a heat-shrinkable polyethylene film.

In the past, a device for the continuous cutting of concrete bricks has been proposed with a basin with fixed, longitudinal walls, to the walls of which are attached rails on which a motor-driven trolley, which in turn is provided with longitudinal and transverse cutting blades driven by another motor (DT). 1,060,303).

The object of the invention is to improve this type of apparatus and the invention is characterized in that the machine is provided with a roller-guided inclined blade adapted to detach and raise a soft bitumen layer from the bottom of the pool, a base to receive the raised bitumen layer and a device for cutting said raised bitumen layer. in the transverse direction.

The details of the invention are presented in the following description with reference to the accompanying drawings, in which Figure 1 shows solidification basins of liquid bitumen seen from above, Figure 2 shows section II-II from Figure 1, Figure 3 shows section III-III from Figure 1, Figure 4 shows a longitudinal section of a machine according to the invention. Fig. 5 shows a section VV from Fig. 4, # Fig. 6 shows an end view of the machine, showing a feeder operating on hanging conveyors of a bitumen packing machine, Fig. 7 shows the machine according to the invention as a whole from above, Fig. 8 shows a longitudinal section VIII-VIII from Fig. 7 · 56496

The tanks in which the liquid bitumen solidifies and is cut into pieces and further processed are located next to each other and have a flat concrete base 1 in which the coolant coils 2 are embedded, which are shown in part in the drawing by a broken line. A coolant flows in these coils, the temperature of which is regulated in a manner known per se and is kept constant at all points in the basin (Figure 1).

Each pool is surrounded by longitudinal and transverse sides. The longitudinal walls 3 are fixed and the transverse walls 4 are placed in the grooves 5> so that they can be moved.

The rails 6 are attached to the longitudinal walls along the length of each cell on both sides (Figure 3) · The rails 30 are arranged for vertically above said receiving machine which moves in the direction F of the basin 1 the longitudinal direction of the basin 31 of adjacent (fig. 2), wherein a trough 32 between the reservoirs, wherein are the conductors of the liquid used to cool the bitumen slabs (not shown in the drawing).

The machine for cutting and handling bitumen bodies comprises a supporting frame 7 resting on two wheel bogies 8 and 9 on rails 6. At least one bogie 8 is arranged to be driven by a gear motor 10.

The movement of the machine is arranged to take place periodically. The forward movement of the machine corresponds to the length of the bitumen bodies 12 (Fig. 5) · To achieve this, limit switch cams are placed along the length of the rails 6, which stop and restart the movement (not shown in the drawings).

Attached to the frame of the machine is a release blade 13, which comprises e.g. a grooved plate attached to the support arms 14 and which rolls on the rollers 15 at the bottom of the basins. This blade runs intermittently with the machine and raises the bitumen layer over the entire width of the pool 33 ·

When the machine has stopped, the carriage 17 with the motor 18 and the blade 19 moves in the transverse direction and cuts the strip or strip 56 566 of a still soft bitumen layer 33 having a strip width equal to the forward movement of the machine (e.g. 450 mm). This carriage has wheels 34 which roll transversely on rails 35 over the entire width of the machine and the carriage moves by means of a pusher 20 arranged to be retracted during the carriage travel and to push the cut bitumen strip 42 periodically on its return path 21 until a second guillotine-type cutter 22 pieces of tape. This cutter 22 is operated by a cylinder 23.

The push lever fitted to the carriage 17 is shown in the drawing (Fig. 5) in the raised position as the carriage travels during the cutting movement of the bitumen layer 33 and in broken lines in the figure when cutting the pieces 12 on the right.

The operation of the equipment is as follows:

The machine, which is resting on its wheels 8 and 9 on the rails 6, moves in the direction of arrow F, irroitusterä 13 rolls on the rollers 15 supported and remove the entire width of the bituminous layer 33> which faces the inclined top surface until the desired width, corresponding to the length of travel of the machine along the tape 42 reaches the support 43 ·

The movement of the machine stops and the motor 18 begins to convey the carriage 17 in the transverse direction on the rails 35 as the blade 19 cuts the bitumen strip 42. The push arm 20 fixed by the carriage shaft 39 to the front of the carriage 17 can be raised in a manner known per se.

When the transversely movable carriage 17 is in the direction of the arrow F j at the end of the cutting movement, it starts to return to the pusher arm-ren 20 is released and causes switch-on.

A new movement of the carriage 17 forward corresponding to the width of the bitumen body (e.g. 342 mm) pushes the bitumen strip 42 onto the plate 24 of the conveyor 25 and the guillotine cutter 22 cuts the pieces to the desired width.

The cut bitumen pieces entering the conveyor 25 rise to the height of the cylinder 26, which pushes them onto a "Polypack" type packaging machine 28.

The conveyor 25 is operated by a motor 27. The bitumen pieces cut and packed in the machine 28 fall on a U-shaped roller track 29 which takes them to a plate conveyor 30.

When the pool is emptied, the machine moves to the adjacent pool by means of cylinders 37 on lowered wheels 36 driven by a transverse gear motor 40 via a gear 38, whereby the wheels 36 roll on rails 30.

Finally, it should be mentioned that different elements and components such as motors, compressors, pressure cylinders, packaging machine, substrate dispenser, etc. can be made or selected differently within the scope of the invention depending on the quality of the material to be cut and packaged.
