Sample bottle transport device

The invention relates to a sample bottle transport device arranged between two cassettes, on whose transport path between the outlet of one cassette and the inlet of the other cassette a coding station and a filling station for the individually transported bottles are provided.

Sample bottle transport devices of this type are used, for example, on milk collection trucks, which accept milk of different qualities from different suppliers. Because of this different quality of milk, it is necessary to take a sample from each quantity accepted. A well-known sample bottle transport device of the type mentioned above is designed as a transport star! The transport star |

has spaces around its circumference for one or more sample bottlesI On its transport route it transports the sample bottles to a code reading station, which reads the code on each bottle and delivers it to a recording device, which compares the sample bottle with the other data on the milk of the supplier in question

Such a sample bottle transport device requires a relatively large amount of space. 5

The invention is based on the object of creating a space-saving sample bottle transport device!

This object is achieved according to the invention in that a guide bridge is provided between the two cassettes, extending from the outlet of one cassette to the inlet of the other cassette, which guides the individual sample bottles on both sides, and in that a driven sliding guide is assigned to the guide bridge, with which the bottles can be transported individually over the guide bridge.

With the invention, the sample bottles are transported directly from the outlet of one cassette to the inlet of the other cassette! This results in a great space saving compared to a transport star, where the bottles are transported on a circular arc!

According to a first embodiment of the invention, further installation space can be saved for the transport device if the slotted guide has two branches separated from each other by an asymmetrically arranged leaf spring, whereby at the reversal point and transition of the two branches, the tip of the leaf spring blocks the exit of the first branch in the transport direction for a bottle located at the reversal point and frees up the entrance of the second branch! In this embodiment, the space saving results from the fact that on the one hand the slotted guide reverses and on the other hand the space required for the guide of the two branches is reduced due to

the movable leaf spring overlaps*

The required installation space can be kept even smaller by bending the second branch in the last section in the transport direction to the side and merging into a third branch of the guide rail running in the opposite direction, whereby the transition from the second to the third branch on the guide bridge is assigned a driven turntable of the code reading station for the bottles. In addition to the compact design, this design also results in a defined position for the bottle, in which the code is read and the bottle can be filled if necessary.

In order to achieve the highest possible throughput with the compactly constructed guide rail with the fewest possible adjustment movements, a further embodiment of the invention provides that the guide rail is in the position in which the transition from the second to the third branch is located on the turntable, with the entrance of its first branch at the outlet of the first cassette. In this embodiment, the next bottle is inserted into the guide rail while the previous bottle is still being filled.

The invention is explained in more detail below using a drawing that schematically shows an embodiment. The individual images show a transport device arranged between two cassettes in plan view in various phases of transport.

The transport device is located between two cassettes ¹ J ₅ ^a designed as rotary conveyors, which carry sample bottles on the outer circumference. The cassette 4 carries the empty

Sample bottles, while cassette 4a collects the filled

sample bottles in a row. 5

The transport device has a guide bridge, which consists of a base plate 2b that extends seamlessly into the storage areas of the cassettes 4,4a and guide rails 2,2a arranged on both sides of the bottles 3 to be transferred. The guide rails 2,2a each protrude with a hook-shaped bent end into the transport path of the bottles on the cassettes 4,4ä!

In the area of the guide bridge 2,2a,2b there is a guide rail. The guide rail consists of two guide plates 1,1a, whose guide edges 5,8,9,10 form three branches 8a,9a,10a. While the branches 8a,9a are separated from each other by a guide edge 5 designed as a leaf spring, the branches 9a,10a are separated from each other by rigid guide edges 9,10 . The guide rails 1,1a, 10a form three branches 8a,9a,10a.

The guide edge 5, which is designed as a leaf spring, is arranged asymmetrically between the two branches 8a, 9a in such a way that the bottle 3 must bend the elastic guide edge 5 while being guided by the branch 8a. 25

The link guide 1,1a is driven in the direction of the arrows a,b via a rod 6 of a motor drive, e.g. a working cylinder! The working cylinder is controlled by a control device (not shown), to which a limit switch 11 for reversing the direction of the link guide 1,1a is assigned!

At the entrance of the guide bridge 2,2a,2b there is a proximity switch 7, which gives a signal when the next sample bottle 3 can be brought into the waiting position! At the outlet of the guide bridge 2,2a,2b there is a

Rotating plate 12, with which the sample bottles can be rotated so that the barcode reader can read the individual code of each bottle. In this position, the bottles are also filled with the milk sample.

The transport device works in the following way:

In the position of the guide rail 1,1a shown in Figure 1, the bottle shown in dashed lines strikes the hook-shaped part of the lateral guide 2 of the guide bridge 2,2a,2b which projects into the transport path of the bottle when the cassette 4 is rotated in the direction of the unnumbered arrow and is deflected into the designated position of the bottle 3 in the area of the guide rail 1,1a . As a result of the displacement of the guide rail 1,1a into the position shown in Figure 2, the sample bottle 3 is displaced on the guide bridge 2,2a,2b in the direction of the other cassette Ha. In the process, the bottle 3 must bend the guide edge 5, which is designed as a leaf spring, sideways. The reversal position is reported to the control device of the drive by the limit switch 11. If the guide rail 1,1a is now moved back in the direction of arrow b, the bottle can only enter branch 9a because branch 8a is closed by the guide edge S, which is designed as a leaf spring. At the end of this movement path, the bottle reaches the position shown in Figure 3 above the turntable 12. The drive of the turntable is activated, the code is read out and the bottle is filled. At the same time, the proximity switch 7* signals that the next bottle can be brought into the waiting position. After the bottle has been brought into this position and the other bottle has been filled, the guide rail 1,1a is again moved in the direction of the
