Definitions
- the invention relates to a device for the production of granules from flowable, viscous masses, which are brought into the form of drops and solidify or gel, consisting of a container filled with the flowable mass with outflow openings, which are intermittently passed through to periodically form droplets perforated tape can be opened or closed.
- a device is known from EP 0 134 944 B1 in which an endlessly rotating belt is guided on two deflecting drums.
- This band is a plastic band, for example made of PVC, and it is guided around two deflection drums, one of which is driven.
- plastic straps are subject to relatively high wear and age relatively quickly. This can lead to the fact that a relatively frequent band change must be provided, which leads to a loss of production.
- it is also disadvantageous in some respects that, after a long period of operation, the belt no longer lies tightly against the outlet slot of the container, so that an insufficient function can occur if the belt tension is not continuously adjusted.
- the invention has for its object to remedy this situation and propose a tape that is stable and is subject to almost no signs of aging. Another object is to provide a method for producing such a band, which allows simple and exact production.
- the band is an elastic band reinforced with inserted metal strands or wires, in which the metal strands or wires are arranged in an exact geometric pattern in such a way that free spaces are evenly distributed over the band surface arise between the metal strands or wires in which the openings of the band are arranged.
- This configuration creates a type of wire tape that can easily absorb the forces that occur during operation. Nevertheless, there is the possibility of arranging the perforation openings in a simple manner.
- the metal strands or wires are arranged in the manner of warp threads in the longitudinal direction of the belt, parallel and at the same distance from one another, and there are metal strands or wires running perpendicular to it, likewise at the same distance from one another as the warp strands provided by weft strands. This results in a lattice belt in which the free spaces are arranged in an evenly distributed manner.
- Such a band has the advantage that it can be produced in a simple manner by first embedding a metal band composed of warp or weft strands in rubber or in plastic and then opening the openings by scanning the position the warp and weft strands are attached in the free spaces formed therebetween. Since the free spaces lie at exact distances from one another, it is possible in this way to mechanically arrange the perforation openings at an exact distance from one another. It is advantageous if that Scanning takes place inductively, which is possible because of the use of metal strands or wires.
- FIG. 1 is a schematic side view of an inventive device for producing granules
- FIG. 2 shows the top view of the lower run of the circulating belt of FIG. 1,
- Fig. 3 is an enlarged view of the partial section along the line III-III in Fig. 2 by the lower strand of the belt and
- Fig. 4 shows a section through the band of Fig. 3 along the section line IV-IV.
- a conveyor belt (1) in particular a steel belt designed as a cooling belt
- an endlessly rotating belt (2) is guided on two deflection drums (3 and 4), which are not shown in detail above the conveyor belt (1 ) are stored in a support frame.
- the deflection drum (3) is driven in the direction of the arrow (5).
- Fig. 2 shows that this is done in that the bearing shaft (3a) of the Umlenktrom ⁇ mel (3) is provided with a gear (6) which is driven by a pinion (7) and an electric motor (8).
- the two deflection drums (3 and 4) are mounted so that their mutual distance can be adjusted to a certain extent.
- the deflection drum (4) is held in a longitudinal slot (9) indicated by dashed lines in FIG. 1.
- the distance between the deflection drums (3 and 4) can be determined using a spacer consisting of the two parts (10a and 10b) (10), which is provided with a screw bolt (11). Spacers of this type are provided on both sides of the deflection drums.
- the circumferential band (2) of which a partial section of the lower strand (2a) is shown in FIG. 3, consists of a plastic which is reinforced by embedded metal strands (16, 17).
- the metal strands or wires (16) are arranged parallel to the running direction of the band (2) at the same distance (a) from one another.
- the metal strands or wires (16) are therefore laid in the manner of warp threads within the band (2). They are crossed at right angles by further metal strands or wires (17) which are of identical design.
- the metal strands or wires (17) therefore form a type of weft thread, which in turn is arranged at a distance (a) from one another transversely to the running direction of the band (2). This creates a wire mesh within the band (2), each of which forms exact square free spaces (18) in which openings (12) can be arranged in a specific pattern.
- the band (2) lies against the curved outer surface of a tubular body (14), which on the outer surface facing the lower strand (2a) has a slot (2) running transversely to the band (2). 15) is provided, which is closed off by the tightly fitting perforated band (2) or, if a row of openings (12) is passed in each case, is released through these openings.
- the tubular body (14) has a guide channel (19) for the supply of viscous and flowable mass, which flows in the direction of the arrow (17) in a flowable, in particular heated, supply. stand is fed. From this guide channel (19) go from holes that open into a slot (15) formed as an open groove. If the guide channel (19) is loaded with the material to be dripped, it can drip into the slot (15) and from there through the openings (12) onto the conveyor belt designed as a cooling belt (1). There the mass solidifies into small lenticular bodies.
- the tubular body (14) is heated in a manner not shown in detail.
- the entire device is also completed by a cover (22).
- Direction indicators (14a and 14b) in the form of radially projecting ribs serve to push the product which emerges from the tubular body (14) back onto the inner surface of the strip with the openings (12).
- the band (2) used in the device can be produced in a very simple manner by first overmolding the metal grid consisting of the metal strands or wires (16 and 17) with plastic on both sides.
- the openings (12) can then be made in a simple manner by inductively scanning the position of the metal strands or wires (16 and 17) using a suitable device. Due to the exact arrangement of the metal strands or wires (16 and 17) and the free spaces (18) formed between them, the openings (12) can then each be in the free spaces, in the embodiment according to FIG. 4 in the middle of the square free spaces, apply in a certain pattern.
