DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention is based on an apparatus for transporting containers intermittently as set forth hereinafter. German Patentschrift 28 53 103 discloses an apparatus of this kind for supplying containers to a filling station, in which apparatus the carriers are lined up one after the other on two guide tracks which are disposed one above the other; the containers are supplied to the carriers on the lower guide track and after they are transferred to the upper guide track, are filled at the filling station. For transferring the carriers, a transfer device with a pivot arm is disposed on each of the two ends of the guide track, which pivot arm transfers the arriving carriers from the upper guide track to the lower guide track or vice versa. To achieve this, the pivot arm swings each carrier out from the first guide track, rotates it on an axis parallel to the feed direction and then sets it onto the second guide track at a 90.degree. tilt. The known apparatus has the disadvantage that processing stations can only be disposed along the upper guide track so that the arrangement of several processing stations is limited to the length of the upper guide track. That is why in order to realize several processing steps, the upper guide track is constructed as very long, which causes the known apparatus to require a large amount of space. Furthermore, at each machine cycle, the containers are shifted further by a step so that the machine cycle, and consequently the capacity of the apparatus, depends upon the longest processing time. The capacity of the known apparatus is therefore relatively low.
ADVANTAGES OF THE INVENTION
The apparatus according to the invention has an advantage over the prior art that processing stations can be associated with both the advance track and the return track, which allows the apparatus according to the invention to be constructed in a particularly compact and simple manner. Furthermore, because of the kinematics of the transfer device relative to the container carriers, these are always supplied in the same direction so that in the formation, they each bump against the same side of the neighboring container carrier. It is possible to constitute intermittent and continuous feed regions by means of the gearing disposed on the container carriers in connection with several transport gears disposed on the advance and return tracks. Hence the processing times of the processing stations can be lengthened in the continuous feed zones without leading to pauses in the processing zones in the intermittent feed zones. Consequently, when there are processing stations with differing processing times, the output of the apparatus according to the invention is particularly high. By the disposition of at least one format changer device for the container carriers on a transfer device, a fully automated change of format can be executed.
Further advantages of the apparatus according to the invention will become more apparent from the claims and the description.
