"Device for transporting open Receptacles for objects "

The invention relates to a transport device with which objects, z, B, hollow bodies or the like. in between parallel the same amount of opposing funding, such as chains, ribbons or the like. guided transport containers open on one side be transported.

In the known transport devices, which painted, printed or otherwise surface-treated objects pick up from a machine for further transport or for drying, each transport container is on the side opposite the longitudinal axis of the container staggered to each other as axes

This attachment of the transport container to the conveying means has the disadvantage that the transport container is in the Twist or twist the steering points of the transport device or VQjklemmen. Another major disadvantage are Twists, caused by unequal elongations of the endlessly circulating conveyor chains or belts when passing through different temperature zones. As a result, trouble-free and vibration-free transport of the transport containers, in particular at high transport speeds, is not guaranteed and also not possible due to the expansion of the transport container due to different temperature zones.

The object of the invention is to provide an improved transport device while avoiding the previous shortcomings With a simple structure and economical operation, a safe position management and a trouble-free transport without tilting, jamming or bending of the transport container is guaranteed.

The transport device described above works as follows:

The transport containers Io are in loading and unloading Transport position, i.e. the container opening is at the top. Will If a transport container Io is passed on, it retains its stable, pendulum-free position - regardless of the incline the roller chains 11, 12 - constantly at; the transport container Io resembles due to its gravity and the diagonally offset, off-center suspension (storage) the fluctuations and Changes in direction of the roller chains 11, 12 or the like from, there it rotates around its bearing pin 13 without swinging.

In the area of the chain guide changing pulleys 19,2o, the transport position is maintained, because the laterally offset by the dimension "a" deflection wheels 19, 2o on the conveying means, such as roller chains 11,12 or the like. arranged bearing bolts 13 carrying a transport container Io are deflected at the same time;

It does not matter whether the transport containers Io are directed up again coming from above , are deflected downwards again via the deflection wheels 19, 2o coming from below (see FIG. 1) or experience another change in direction.

If a transport container Io reaches the deflection wheels 21, which are used as a tilting device and are preferably mounted in an axial line, one bearing pin 13 is deflected earlier and the transport container Io begins to tilt - due to the forced guidance - after both bearing pins 13 rotate around the deflection wheels 21 by about 180 ° , have the transport container Io has turned to I8o ° and is with its open Since · downward (see Fig. Fig. 1). The transport container Io attaches a section of parts to the Durohlaufweg in a tilted position, preferably offset by 180 ° (with the opening

The same applies to the second tipping station and after a transport container Io the deflection wheels 21 with has rotated its bearing pin by 180 °, its filling opening is again on top (see Fig. 1).

The transport device according to the invention is characterized by Simplicity in production and an inexpensive way of working. A particular advantage is in the pendulum and tilting seen safe storage during forwarding and redirecting.
