Abstract
An apparatus for moulding pieces of chewing gum is described in which a gumming up by pieces of cut chewing gum is prevented. The apparatus is provided with rotating cooperating moulding chambers (14) and moulding dies (20, 21) and has a spraying nozzle (25) for powdered release agent which is blown, finely divided, against the working surfaces of the moulding chambers and moulding dies where, as a thin coating, it prevents a direct contact between the pieces of chewing gum and the working surfaces. A uniform coating may be achieved when the sprayed release agent is electrostatically charged. <IMAGE>
Description
SPECIFICATION
Apparatus for Moulding Pieces of Chewing
Gum
State of the art
The invention originates from an apparatus for moulding pieces of chewing gum according to the type set forth in the main claim. Such apparatuses, for example known from German
Specification 24 56 480, have as a rule been used up till now for moulding hard sweetmeats.
However, it is also worthy of endeavour to so set up such apparatuses that chewing gum, which is difficult to handle due to its tackiness, can also be processed therewith.
Indeed, an apparatus for producing strips of chewing gum which are cut off from a string is already known from United States Specification 2 256 190. In order to overcome the tackiness of the outer surface of the string, the string, still warm after leaving the extruder, is conveyed through a container in which its surface is coated with sugar.
Advantages of the Invention
The apparatus in accordance with the invention comprising the characterising features of the main claim has the advantage that the working surfaces of the moulding tool and the moulding chambers receive an adherent separating layer in a simple manner before they come into contact with the mass of chewing gum.
In this manner, the cut surfaces or gripping surfaces of the blanks separated from the preferably powdered string and at which the tacky mass of chewing gum is exposed, cannot contact the working surfaces of the moulding tool and chambers directly. A gumming up and glueing up of the moulding tool and chambers is prevented thereby so that a faultless operation of the apparatus is guaranteed.
Drawing
An embodiment of the invention is illustrated in the drawing and is described in detail in the following specification. Figure 1 shows a moulding apparatus in simplified cross-section,
Figure 2 shows the moulding apparatus according to Figure 1 in longitudinal section and Figure 3 shows a spraying device in longitudinal section to a larger scale.
Description of the Embodiment
For moulding pieces of chewing gum 1, a string 2 is first of all formed from a mass of chewing gum by an extruder and its surface is coated with a powdered release agent 3 from a powder metering apparatus 4. The string 2 is rolled and drawn out by a plurality of pairs of matching rollers 5. From this thus prepared string 2, which can consist entirely of a chewing gum mass or of a tube of chewing gum mass with a filling of pasty or liquid enjoyable material, cushion-like blanks 6 are then separated in the apparatus in accordance with the invention and these are then moulded into pieces of chewing gum 1 by pressing and stamping.
The apparatus has a drum mounted on a driving shaft 10 and which is made up of two carrier rings 11, 12, a chamber ring 13 having moulding chamber 14 uniformly distributed in a circle and of an inner gear ring 1 5 with radially outwardly projecting teeth 1 6. An outer gear ring 1 9 with inwardly directed teeth 1 8 is associated with the inner gear ring 1 5 and is in the same plane, its inner diameter being greater than the outer diameter of the inner gear ring 15 and being mounted on rollers 1 7 eccentrically with respect to the inner gear ring 1 5 so that the teeth 16, 1 8 of the two gear rings 16, 17 roll over one another over a predetermined region of angular rotation.
Within this angular region, chambers are defined by the teeth 1 6, 1 8 and by the cavities lying between them which are aligned with the moulding chambers 14 of the chamber ring 13.
On both sides of the chamber ring 13, moulding dies 20, 21 are displaceably guided in flanges on the carrier rings 11, 12, each respective pair of which aligns with a respective moulding chamber 14 in the chamber ring 13.
The moulding dies 20, 21 cooperating in pairs, are forced by springs 22, 23 away from the chamber ring 13 against fixed pot cams 24, 25.
These pot cams 24, 25 each have a slide track which so control the axial displacement movement of the moulding dies 20, 21 by means of axially forwardly and rearwardly projecting regions, that the moulding die 20 takes up a retracted position (Figure 3) remote from the moulding chambers 14 of the chamber ring 13 in the region of the entry of the string 2 of chewing gum into the apparatus, and that, in the subsequent region in the rotary direction of the drum, the moulding dies 20, 21 of each pair are moved against the associated moulding chamber 14 whereby the moulding die 20 traversing the gear ring 1 7 introduces a blank separated from the string 2 by the teeth 1 6, 1 8 into the moulding chamber 14 and whereby each pair of moulding dies compresses the blank 6 in the moulding chamber 14 from both sides and that finally the moulding dies 21 arranged on the side of the chamber ring 13 are retracted into their initial position and the opposite moulding dies 20 are then advanced still further so that the finished mouided pieces of chewing gum 1 are forced out of the moulding chambers 14 and are then likewise returned to their initial position.
In order to prevent tacky masses of chewing gum, which occur at the surface during separation of the blank 6 from the string 2 thus no longer covered by the release agent previously applied to the string, from coming into contact with parts of the moulding dies 20, 21 and moulding chambers, their surfaces are dusted with a powdered release agent, for example powdered sugar, maize flour, talcum or the like. For this purpose, a spraying nozzle 25 is arranged in the region of the moulding dies 20,21 in which they are located in a retracted position with respect to the moulding chambers 14 and the moulding chambers 14 are open. The spraying nozzle 25 is mounted at the end of a supply duct 26 provided with a feeding funnel 27 which is uniformly supplied with release agent 29 from a metering device 28, preferably a worm metering device.A compressed air line 30 provided with a nozzle 31 projects into the supply duct 26 through which compressed air from a compressed air source (not shown) emerges. The compressed air entrains the existing powdered release agent and sprays it at the end of the nozzle 25. The spraying nozzle 25 preferably has two opposite openings 32, 33 which are directed towards the end surfaces of the moulding dies 20, 21. The release agent finely divided by the compressed air forms a dust cloud in the described angular region between the moulding dies 20,21 and the moulding chambers 14, from which a thin coating of release agent is deposited on the boundary surfaces.
In order to achieve the required uniform deposit of release agent, the release agent particles can be electrostatically charged so that they are attracted by the surfaces to be coated.
For this purpose, anodic charged electrodes 34, 35 are arranged in front of the openings in the nozzle. On the other hand, the parts to be coated which come into contact with the chewing gum mass, such as the moulding dies and the moulding chambers, are connected to the anode.
Claims (6)
