DESCRIPTION:
BRIEF SUMMARY
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a national-phase application of PCT/CH 81/00028 filed Mar. 4, 1981 and based upon Swiss national application 1698/80.0 filed Mar. 4, 1980 under the International Convention.
FIELD OF THE INVENTION
The present invention relates to an apparatus for the overhead or upside-down handling of bottles and the like with a conveying system rotating continuously in a vertical plane between a feed point and a discharge point having resilient clamping members for the clamping drive of the bottles and the like for moving them past a handling device in overhead manner.
In connection with the mass production, reprocessing or reclaiming of wide-necked and narrow-necked vessels, particularly bottles and the like made from glass, plastics, etc apparatuses of the aforementioned type are employed which bring the bottles and the like temporarily into an upside-down position in order to blow and/or wash therefrom in said position foreign bodies and residues such as grindings, dust, glass fragments, etc, to which end corresponding handling devices are equipped with air or water jets.
In known apparatuses of this type, the conveying system comprises a conveyor chain rotating in a vertical plane by means of two chain wheels and which has gripper means for displacing the bottles and the like.
The disadvantage of such apparatuses is that the bottles and the like must be fed in and/or out tangentially, which requires special measures to permit the incorporation of such apparatuses into existing production lines. It is also a disadvantage of such apparatuses that they require means for expanding the gripping means for receiving or releasing the bottles and the like. It is also disadvantageous that it is not easily possible to re-equip the known apparatuses with respect to their feed and discharge points, so that they are generally restricted to the original design. In addition, the handling or processing device such as an air jet is restricted to its point of installation.
OBJECTS OF THE INVENTION
The problem of the present invention is to provide an apparatus of the aforementioned type which is able therefore without difficulty to receive bottles and the like between its clamping members or to release the same again, whilst in particular permitting a free adaptation to all existing conveying systems of the particular production line.
SUMMARY OF THE INVENTION
According to the invention, this problem is solved in that, the conveying system comprises two synchronously rotating endless chains having a conveying side and a return side in each case, the conveying sides moving in the same direction and form parallel clamping jaws with an adjustable spacing, the reversal points of the two endless chains forming the feed-in point or discharge point for the bottles and the like, in the vicinity of the feed-in or discharge point the conveying path formed by the endless chains extends at least approximately horizontally and the handling device acts on the outer and/or inner vertical turning path of the conveying path.
It is possible without difficulty for the feed and discharge points to be in the same or different planes with respect to the upper or lower conveying path.
According to a preferred embodiment of the apparatus according to the invention, the distance between the conveying sides is adjustable and the feed point is laterally displaceably supported relative to the discharge point.
The construction can be such that the support means for the endless chains are hydraulically or mechanically adjustable by hand.
It is also advantageous if on the clamping jaw side, the endless chains have elastic clamping members.
It is advantageous if the handling or processing device comprises air and/or water jets, it being appropriate if the construction is such that the distance between the handling device and the conveying path formed by the endless chains is adjustable.
As a result of these measures, it is now possible to adapt the apparatus for the overhead handling of bottles and
