Definitions
- the invention relates to a device for forming drops from viscous, flowable masses, which are arranged in a container with at least one wall provided with several rows of openings and can be cyclically pressed out through a row of openings in the form of a drop as soon as they move during the movement of the wall comes with a non-co-rotating outlet area, whereby for heating in particular the remaining masses of the wall still remaining in the openings and / or * the outlet area is assigned at least one heating device.
- the rotating tubes have generally been made of stainless steel for reasons of corrosion and wear. However, since this material has very poor sliding properties, a gap has generally been created between the fixed inner container and the rotating tube. Since the heating of such rotoformers takes place from the inner, stationary body, it therefore occurs in some products that the outer rotating container and the residual masses adhering to it cool down too much, so that the threads which differ from the latter pull the drops deposited on the cooling belt towards the rotating outer surface of the container, not always tearing them off so that they fall back on the cooling belt in the drops formed. Therefore, in such materials is a proper and staubrous- granulation is not always' possible.
- the present invention is therefore based on the object of designing a device of the type mentioned at the outset in such a way that heating of the moving wall which is tailored to the need is possible without the risk that the product is damaged by overheating or that its flash point or the ignition temperature is reached .
- the heating device is an inductively operating heater.
- the heating device in the manner of an induction hardening system can be provided with an induction coil which is assigned to the container wall and which can be designed as a transmission tube through which coolant flows.
- the inductive heating of the existing stainless steel or other suitable materials of the moving wall or the outlet region a controllable manner can be heated in a relatively simple and well ', without the temperature of the heater is too high you.
- the transmission coil can be cooled so that it does not itself reach temperatures that can become too high.
- the heating can be carried out in a very simple manner.
- a heater according to the invention can also be assigned to a circulating belt or the fixed outlet part cooperating with it, provided that the belt is made of an inductively edible material, e.g. is made of steel.
- FIG. 1 shows a schematic cross section through a drop former in accordance with the invention with a fixed inner container and a perforated outer tube rotating about it,
- FIG. 2 shows the schematic representation of the drop former of FIG. 1 in a top view with the induction coil for heating the outer tube, but on a smaller scale
- Fig. 3 shows a cross section similar to FIG. 1 but through a
- FIG. 4 shows a schematic longitudinal section through the central axes of the two rotating rollers of FIG. 3.
- FIG. 1 shows a section along the line I-I of FIG. 2, but on a greatly enlarged scale
- a drop former (2) is arranged above a conveyor belt (1) designed as a cooling belt.
- the cooling belt (1) is moved in the direction of the arrow (3) and takes up the material dripped out of the drop former in the form of pastilles (4), which more and more as the cooling belt (1) moves in the direction of the arrow (3) solidify more and then can be removed from the belt.
- the drop former (2) consists of a cylinder-like inner body (6), which is mounted in a stationary manner (not shown in detail) in stands (4) arranged laterally from the cooling belt (1), around which a cylindrical tubular container (7) is rotatably arranged is also received in bearings (not shown) in the uprights (5) and can be set in rotation in the direction of arrow (8) in FIG. 2 by a motor.
- This type of formation of a drop former is known per se and is therefore not described in detail.
- the rotatable cylindrical outer container (7) has continuous openings (9) on its entire circumference, which run in rows parallel to the axis of rotation (10) along surface lines of the container (7).
- the fixed inner body (6) has an axial feed opening (11) for the material to be dripped, which is laterally supplied to this channel (11) in a manner which is also not shown in detail because it is known in a flowable form.
- This viscous material to be dripped arrives then through a plurality of branch channels (12), to a chamber (13) which also runs parallel to the axis (10) and can be fed from there via bores (14) to a nozzle bar (15) and a groove-like outlet region (16) of the nozzle bar (15) from where, when the rows of openings (9) are cyclically aligned with the outlet area (16), the outside of the rows of openings drips onto the cooling belt (1).
- the supply of material to the openings (9) is terminated as soon as the rows of openings reach the rear edge of the nozzle bar (15) in the direction of rotation (8).
- threads (17) will form in part due to the viscosity of the material to be dripped, which should then tear off as the outer container (7) moves further, and because the direction of rotation (8) and the direction of movement (3) of the cooling belt correspond accordingly can be selected and coordinated with one another, then sink back into the pastilles-like piles (4) of the material on the cooling belt (1) and should as a rule fuse with them.
- the drop former (2) of FIGS. 1 and 2 is therefore provided with an induction coil (18) which, in the exemplary embodiment, essentially corresponds to a straight tube which extends parallel to a surface line of the rotating container (2) and to which the coil windings ( 19) are assigned accordingly.
- the induction coil rod thus formed is formed as a hollow tube and can be supplied - in a manner known per se - in the sense of the arrow (20) in FIG. 2 with a coolant which, after flowing through the cavity (2) in the direction of the arrow (21) emerges again.
- the coil (19) itself is operated in a known manner in the manner of a work coil of an induction hardening system, the rotating outer container (2) corresponding to the workpiece and the coil (19) being connected to a high-frequency part (24) via a high-frequency transmitter (23) , which in turn is provided with a power supply part (25).
- the rotating outer container (2) is also assigned a temperature sensor (26), the sensor part of which is arranged in the vicinity of the circumference of the container (2). The degree of heating or the temperature of the container (2) can be detected and controlled via this sensor (26). Since the rotating container (2) is made of stainless steel in the usual way, it can be heated inductively in a simple manner. The temperature reached can be measured and adjusted using the temperature sensor (26).
- the transmission part (18) serving as the work coil can itself be kept at a very low temperature by the possible cooling, so that requirements, for example for explosion protection, can easily be met. It is also possible to control the temperature of the container (2) exactly as is required for the product to be pressed.
- the fixed inner container (6) can also be made of stainless steel. There is therefore a circumferential gap for reasons of friction between it and the rotating outer container (7).
- the inner container (6) which can of course also be provided in a known manner with additional heating options, for example in the form of heating channels (27) through which thermal oil flows, can therefore also be heated inductively. This heating can also be controlled by the temperature sensor (26).
- the selected embodiment makes it possible to heat the drop former (2) in the region of the rotating container (7) and the outer regions of the inner container (6) facing it in such a way that this is in the openings (9) after leaving the outlet region .es (16) remaining material can be sucked back into the eccentric gap (28) between the inner container (6) and the outer container (7), so that from there it can be put back into the openings in a drip-ready condition before reaching the outlet area and is then released together with the material to be dripped out in the outlet area (16) as a new drop onto the cooling belt (1).
- a guide body (29) is also assigned to the outer circumference of the container (7), which also mechanically ensures that material still adhering to the outer circumference is pressed back into the openings (9) before the outlet region (16) is reached.
- (29) is heated.
- it can have flow channels
- 3 and 4 show another exemplary embodiment in which the heating of a rotating outer body and / or a rotating inner body is also carried out inductively.
- a cylindrical roller (31) is mounted on a frame (32) above the cooling belt (1) moved in the direction of the arrow (3) and is provided with axially extending toothed strips (33) on its entire inner circumference .
- the openings (9) are provided between each two adjacent toothed strips, which are arranged in the same way as in the embodiment of FIG. 1 in each case to rows of openings running along a surface line.
- This outer roller (31), which according to FIG. 4) is each held at 1 'with its ends in a bearing ring (34) and of course can also have a greater axial length than shown in FIG. 4, is via its bearing rings (34) in Retaining rings (35) arranged, which in turn on Ab- support arms (36) are held on support columns (37) of the frame (32).
- a likewise rotating squeezing roller (38) Arranged inside the rotating outer roller (31) is a likewise rotating squeezing roller (38), which is provided on its entire outer circumference with toothed ridges (39) which correspond to the toothed strips (33) of the outer roller (31) and with these in the region of a Vertical plane (40) come into engagement, which is also perpendicular to the cooling belt (1).
- the squeezing roller (38) is hollow and is mounted with bearing pins (41) protruding to both sides in bearing rings (42), which in turn have a bearing
- Support arms (43) are attached to the columns ⁇ • e ⁇ • n (37).
- Bearing pin is provided with a drive pinion (44) so that the squeeze roller (38) and the outer roller (31) engaging with it can be driven to rotate in the direction of the arrow (45) via this drive pinion (44).
- the direction of rotation of the two rollers (31 and 38) is selected so that the resulting tangent of movement in the region of the vertical plane (40) corresponds to the direction of movement (3) of the cooling belt (1).
- an induction coil (18 ') is assigned to the outer roller (31), which in the same way has a cavity (22') through which coolant can flow and the coil arrangement according to FIG. 2, but which is not shown again in detail.
- the induction coil (18 ') is attached to the columns (37) via holding arms (46).
- the holding arms (46) can at the same time be designed as supply lines for the coolant and can be provided with the electrical supply cables.
- the squeezing roller (38) is also assigned an induction coil (47), the feed lines for the electrical energy as well as for the coolant in a manner not shown in the hollow squeezing roller (38) and within the axially extending one Bores (48) provided shaft stub (41) are laid.
- the outer roller (31) and the squeeze roller (38) are therefore made from a ferritic material, for example from carbon-containing steel or iron, then even in such an embodiment, heating and tempering of the intermeshing elements can be carried out very sensitively Rotating body and thus also reach the material to be pressed, which is introduced axially into the space (49) between the squeezing roller (38) and the outer roller (31).
- the arrangement of the induction coil (47) has the major advantage that heating is also possible in the area which is just before the exit area (16), so that the viscosity of the material to be pressed is exactly at the exit points can be achieved and maintained, which is best for the desired drop formation.
- a temperature sensor for controlling the heating can of course also be assigned to the outer roller and / or the inner roller. It is also possible to arrange the induction coil associated with the squeeze roller (38) in the space (49) between the outer roller (31) and the squeeze roller (3.8) or to provide it there in addition to the induction coil (47) arranged on the inside.
