Definitions

the invention relates to a machine for producing cup containers made of paper or the like with at least one conical mandrel as a carrier for a cup jacket projecting beyond the mandrel at the thicker end, a device for forming a support for the edge of the cup jacket projecting beyond the mandrel and a device for Flanging this edge.
cup coats in order to obtain a proper connection of the overlapping edges of the jacket blank, must be supported over the entire seam length by the mandrel carrying them. If the edge of the cup shell is to be crimped, for example after inserting a cup base, the edge of the shell to be crimped must protrude beyond the mandrel.
the jacket which must first be closed at its overlapping edges and later flanged to a bottom, has to be transferred from a mandrel carrying it during the first process to another, shorter mandrel for the second process
it is known to use a shorter mandrel for both processes and to temporarily use the free edge of the jacket while closing the jacket seam to support the mandrel in connection with the supporting device.
the mandrel generally rotates in a plurality on a turntable or on another conveyor
the support devices and the flanging device are arranged only once, in a machine-fixed manner, in the machine stations assigned to the closing or flanging. Since they operate in different stations, they do not interfere with each other. They also do not collide with the mandrel holder provided on the thick end of the mandrel because they act on the narrower jacket edge.
the invention is based, to avoid in the effort of implementation with regard to the processing of the further jacket edge the task.
the solution according to the invention consists in that the thicker end of the mandrel is provided coaxially opposite and displaceable towards and away from it, a support cone and a flanging ring which radially escapes in the position of the support cone close to the mandrel.
these parts do not interfere with each other, however, because the support cone can reach through the flare ring with radial expansion thereof, while the flare ring is not hindered by the support cone, because it is expedient anyway along a conical guide, which in this case is slightly different from the Support cone can be formed, is moved in the direction of the surface lines of the edge to be crimped.
the mandrel 2 On a support part 1, which may be formed by a turntable, the mandrel 2 is rigidly attached via the shaft 3 by means of the screw 4.
the support cone 5 On the shaft 3, the support cone 5 is coaxial with the mandrel 2 and a bearing bush 4 slidably mounted in the longitudinal direction. It has the same taper as the mandrel 2 and its thinner end has the same diameter as the thicker end of the mandrel 2 so that the support cone forms the smooth continuation of the mandrel surface when it is pushed towards the mandrel. It is therefore able to support the free edge 6 of a cup jacket 7 against external forces during the sealing of the jacket seam. The support cone 5 is pushed into the inactive position shown by a spring 8.
a plurality of rods 9 distributed uniformly on the circumference are fixedly connected to the lower end of the supporting cone 5 and penetrate axially parallel to the carrier 1 and are firmly connected to a yoke 11 at the end.
the yoke 11 can be guided by a plurality of axially parallel bolts 13 which are uniformly distributed on the circumference and which are firmly screwed to the carrier 1. Only one of the rods 9 and the bolts 13 is shown in the drawing.
a roller 14 cooperates with the underside of the yoke 11 at the end of a lever 15 which is fixed to the machine at 16 and can be actuated in the direction of the arrow 17 by means not shown at the other end.
the yoke 11 with the rods 9 is pushed upwards, taking the support cone 5 with it, until it rests on the end face 18 of the mandrel 2.
the sleeve carries a guide 25 on the mandrel side, which holds the flange ring 28 in a radial plane between two flanges 26, 27.
This crimp ring consists of a plurality of segments which are divided radially and are drawn together by a worm spring 29, so that their conical inner surface 30 abuts against the conical outer surface 31 of the supporting cone.
the contact with the support cone determines the respective radial position of each individual segment of the crimp ring and thus also its always circular arrangement.
the flange 26 forms a radial outer surface 33, on which the roller 34 acts at the end of a lever 35, which is mounted on the machine at 36 and can be actuated in the direction of the arrow 37 at the other end.
the roller 34 presses the guide device upward via the flange 26. This also moves the flanging ring towards the cup. During this movement, the ring segments follow the direction predetermined by the outer surface 31 of the support cone, which is parallel to the surface lines of the cup shell 7. Conversely, the segments are able to move radially outwards when the support cone 5 is moved upwards.
the device works in the following way: After the jacket blank has been wound onto the mandrel 2 in a known manner, its overlapping edges (not shown in the figure) are sealed by heating jaws pressing from the outside. To support the free cup rim 6 during this process, the support cone 5 is by the Actuator 17 pushed upwards, whereby the flanging ring can deflect radially. The free edge 6 is later crimped in that the crimp ring 28 is raised by the actuation 37 after the support cone 5 has returned to the rest position. Both processes can take place without the support cone and the flanging ring hindering one another. On the contrary, the support cone promotes the proper functioning of the crimp ring by forming a guide surface for it.
