Definitions

  • the invention relates to a pressing element for metal foil blanks placed around the neck and the head of bottles in a labeling machine, which can be moved axially against the end face of the bottle head and an internally bell-shaped housing and an elastically deformable and at least on its side facing the end face of the bottle head Front has a plate made of elastic foam, which is arranged in front of the opening of the housing facing the end of the bottle and is supported on the back on the edge of the housing.
  • the plate When the pressure element is lowered onto the end face of the bottle, the plate is pushed back against a spring-elastic support element while being deformed, the plate being pressed radially against the sides of the bottle head like a hood due to the rounded surfaces of the bell-shaped housing.
  • the front of the plate which consists of elastic foam and acts directly on the metal foil blank, folds particularly when the plate has such a large diameter that it does not only cut the foil blank at the top of the bottle head, but up to is able to press below the bottle head.
  • Such a deformation of the plate side acting directly on the film has an unfavorable effect on the surface of the film blank which is as smooth as possible for optical reasons.
  • the strain on the film blank to stretch when pressed is so great that damage cannot always be avoided.
  • the load is high because the plate is designed so that when the pressure element is lowered it must slide along the inside of the bell-shaped housing so that the plate can wrap around the bottle head in a hood-like manner.
  • a foam body designed as a solid or hollow truncated cone sits in a pot-shaped housing which is adapted to the shape of the foam body, on the walls and bottom of the foam body is supported (DE 31 53 154 C2, DE 34 37 283 A1). Since the foam body is supported both on the walls and on the bottom of the conical housing pot, its possibility of evasion when the bottle head is immersed in the foam body is limited. As a result, the foam body exerts pressure on the side of the bottle head. In practice, it has been shown that the load on the film blank is large during this pressing process. Therefore, the fully formed truncated cone has not proven itself in practice. The conditions for a hollow truncated cone are more favorable, but the load on the film material is still high.
  • the invention has for its object to provide a pressure element with which the film blank can be pressed as smoothly as possible and with the greatest possible axial length on the bottle head with the least possible load.
  • the plate can be smoothly applied on all sides around the bottle head itself to a region below the bottle head with little axial force. There is no wrinkling of the front of the plate which acts directly on the film blank. There is also no dangerous strain on the film blank.
  • These positive effects for the smooth pressing are based on the fact that, in contrast to the prior art, the plate does not slide with its rear side over the rounded inside of the housing, but rolls on it, the annular bead interacting with it in the axial direction of the housing tapering free cross section of the bell-shaped housing ensures that sufficient radial pressure is still exerted on the bottle head in the lower head area. It also helps that the radial roll length on the back of the plate is larger than the diameter of the plate in the relaxed state because of the special shape of the back of the plate.
  • the pressing element shown in FIGS. 1 to 3 consists of a housing 1 and a flexible plate 2.
  • the flexible plate 2 sits in front of the lower opening 4 of the housing 1 facing the front side of a bottle 3 and is here through an outside on the housing 1 clamped retaining ring 5 held.
  • the lower area of the housing 1 is formed by an insert body 6, the rounded inner wall 7 of which has the shape of a bell.
  • the plate 2 is designed as a foam body, the front of which faces the bottle 3 is open-pore.
  • the plate 2 has an annular bead 8 on its rear side at the peripheral edge. Except for the open-pore front, the entire plate 2 is covered with a skin 9, which is formed by the closed-pore design of the foam body.
  • the plate 2 deforms in the manner shown in FIGS. 2 and 3 upon axial movement of the pressing element in the direction of the bottle 3.
  • the back of the plate 2 rolls on the bell-shaped wall 7 and the annular bead 8 ensures that the front edge of the plate 2 is pressed radially against the sides of the bottle head. This pressing is free of creases and distortion.
  • the resetting takes place solely on the basis of the inherent elasticity of the plate.
  • FIGS. 12 and 13 show that the disk 51 facing the end face of the bottle 3 can have an annular collar 53 which extends in the radial direction and serves to detect a greater axial height of the bottle head.
  • FIGS. 4, 5 and 12, 13 differ from that of FIGS. 1 to 3, except in the cut-in plates 14, 40, 50 in the retaining rings 14, 45, 55.
  • the retaining rings 14, 45, 55 are made of elastic material, for example rubber. They engage with a collar 16, 44, 54 in an outer annular groove 17, 46, 56 of the housing 21, 47, 57.
  • the plates 14, 40, 50 are held in front of the opening 23, 49, 59 of the housing 21, 47, 57 with a radially inwardly directed, easily deformable lip 22, 48, 58, on the edge of which they engage with their annular bead 24, Support 30.60. By deforming these lips 22, 48, 58, the plates 14, 40, 50 can be easily replaced.
  • FIGS. 5, 12, 13 An essential difference between the exemplary embodiments in FIGS. 5, 12, 13 and the exemplary embodiments in FIGS. 1 to 4, which further improves wear resistance, is that it is not designed as a full-volume body, but is instead radially ribbed.
  • the rear pane 42 consists of a flexible, highly wear-resistant plastic. Ribs 33 extending radially to the peripheral edge are formed therein, between which intermediate spaces 34 are formed.
  • the base of each rib 33 is formed by a sector-shaped area which is delimited towards the inside of the plate 40 by a circle 35, the diameter of which approximately corresponds to the diameter of the bottle head.
  • the total circumference of the individual ribs 33 on the peripheral edge of the disk 40 is dimensioned such that the ribs 33 in the deformed state shown in FIG. 3 of the plate 40 do not overlap. are arranged by closing the spaces 34. This is achieved in that, in the undeformed state, the width of the ribs 33 corresponds approximately to the width of the intermediate spaces 34 and the height of the ribs 33 increases from the center of the plate 40 to its edge.
  • the disk 41 arranged in front of the ribbed disk 42 consists of an open-cell foam such as foam rubber.
  • This disc 41 is placed around the neck and head of the bottle 3 in such a way that the film blank is pressed evenly and smoothly onto the head and neck of the bottle 3.
  • the disk 41 has, along its circumference, approximately radially incised notches 36, by means of which individual webs 37 are formed, which are arranged without overlap with one another when the disk 41 lies against the neck of the bottle 3. This also prevents the foam from unfolding in the area of the circumference of the pane 41, so that the film blank is also applied smoothly in this area.
  • the rear pane 65 according to FIGS. 10 and 11 has an opening 66 in the central region, the opening 66 of which Diameter corresponds approximately to the diameter of the head of the bottle 3. This is intended to achieve a certain level compensation, so that bottles of different heights can be foiled without retrofitting the pressure element.
  • FIGS. 12 and 13 essentially corresponds in its construction to the embodiment of FIG. 5, its flexible plate 50 is designed differently.
  • Its front disk 51 has a slightly larger diameter than the rear disk 52.
  • the rear disk 52 is also designed in the manner of a jumping mechanism.
  • the disk 52 jumps from the undeformed state, as shown in FIG. 12, to the state shown in FIG. 13 and maintains this state even after relief.
  • the pressing process can now take place in such a way that only the front disk 51 is deformed during the axial movement of the bottle 3 against the plate 50.
  • Significant deformation of the disc 52 is not required. This only serves as a flexible abutment. Therefore, the plate 50 is practically no longer subject to closure. For this reason, such a pressing element is particularly suitable for use in a labeling machine with very high stroke rates.
