Each slide 20 consists of a main part or
Body 21 shaped metal profile with a substantially
U-shaped section, the center leg of which is designated by 21a
is and its two parallel. Legs are denoted by 21b and 21c, and from a laterally or next to the leg 21c of the part 21 extending support surface 22, the parallel
is arranged to the middle leg 21a. With is the distance
between the two parallel legs 21b and 21c and taken between these legs. The support surface 22 and the leg 21c of the part 21 are provided with tubes 23 or the like made of plastic, which are intended to enable the bottles B to slide.

The slideways 2O are on the generally designated 3O Positioning or setting means attached and have according to In the illustrated embodiment, four vertical shafts 31, which in pairs next to the two ends of the two side surfaces 1Oa and 10b of the frame IO are arranged, the two shafts

7703340 08/04/77

are assigned to one and the same side surfaces / z. B. the Surface 10a, and receive the two ends of one and the same slide 20, which is arranged along this side surface. The vertical shafts 31 are rotatably attached, each of which has a lower end 32 in the form of a spherical cap which is provided in a pivot 33 or the like in engagement with a spherical support stop 34 and is attached to the lower part of the frame 10. the Shank is connected to the frame 10 in a form-fitting manner at its lower part by engaging in a horizontal Cross member 35 held.

Each slide 20 is lined up over its two ends on the two vertical shafts 31, which are assigned to one and the same side surface of the frame, and for this purpose is provided with two openings 24 , which pass through the horizontal leg 21a of its part 21 and the Allow the shafts to pass through. Said openings have an elongated shape and extend perpendicular to the longitudinal edges or longitudinal edges of the slideways, that is, perpendicular to the side surfaces 10a and 10b of the frame 10, so that the slideways can move perpendicularly to the side surfaces of the frame 10.

The positioning device also has bracing elements which consist of blocks or supports 36, which can be made of plastic. Each block 36 generally has the shape of a cylinder with a circular section,

7703340 0408.77

has two parallel end faces and is of an axial bore 37 traversed in order to be lined up on a shaft 31 can. The diameter of this cylinder is denoted by D. Each block 36, on the other hand, has on a part above a profile in the form of a cam 38 which is also circular Has cross section, but is eccentric to the bore 37, wherein the diameter D2 of this profile is smaller than D1 and slightly smaller than the inner diameter D between the two wings 21a and 21b of Part 2.1.

The slideways 20 are lined up with strut elements 36 inserted between two successive slideways on the shafts 31 in such a way that two rows of slideways 20a and 20b, which are arranged one above the other, are formed, the slideways representing one and the same space and one and the same distance between them have: d for the slideways 20a and d ¹ for the slideways 20b, where d '> d applies. The slideways .20 are arranged so that they cover the cam profiles 38 of the blocks 36, ie their part 21 is in the position of an inverted U. The one and the same row of slideways associated spacer elements (the elements 36a for the slideways 20a and the Elements 36b for the slideways 20b) offer one and the same angular alignment with respect to the shafts 31, with which they are positively connected by means of S-ciffc £ si 39. The orientations are such that for a given angular position of the shafts 31 the series of slideways, e.g. B. the row 2Oa is located protruding towards the interior of the frame and the

7703340 08/04/77

whose row of slideways 20b, in contrast, relates to
the first row of slideways is withdrawn. Be it
noted that there is such an arrangement of slideways
it is always possible to set it up so that at least one
Slideway is common to several rows of slideways; in the case shown is one of the sliding ™ or guide tracks 20a-b
arranged so that it can neutrally belong to one or the other row 20a or 20b. This slide 2oa-20b, which consequently has no reason to be withdrawn, is related to
of the shaft 31 and for this purpose provided with an opening 24a-b which, in contrast to the openings 24, is circular, just like the strut element 36a-b, which is assigned to it, is freely rotatably mounted on the shaft 31, ie that it is without a pen.

The adjusting device for the slide or guide tracks 20 finally has a driving mechanism for simultaneous rotation of the shafts 31, generally denoted by 40 i ^ t. This mechanism essentially comprises an endless chain 41, which is attached to the shafts 31 at the upper ends Drive wheels 42 and after passing through countershaft pin rollers 43 meshes with a drive drive wheel 44, which in turn can be carried along by a shaft 45 provided with a handling lever 46.

It can be seen that you can turn the lever 46 by 180 ° Has sen, the vertical shafts 31 and consequently the bracing elements are also obtained 36 can swivel 18Ο ° that rotates with

the shafts are positively connected, whereby a slideway row (the row 20a) is taken into the working position and this slideway row can accommodate the loading surfaces or trays or trays, and the other row (the row 20b) is brought into the retracted position, ie the outside -Operating position. In the course of this handling , only the slideways remain, such as 2. B. the slideway 20a-b _# on the j Plata, which form part of one or the other row / the slideways 20a and 20b slide according to arrow P2.

The embodiment described can with; numerous changes are provided without departing from the scope of the invention. So you could z. B * a number of rows of slideways and provide for blocks larger than two. The number of slideway rows envisaged, i.e. H. the possibility of customizing the Loading and unloading device is noted depending on the adaptation options of the shelves of the treatment chambers selected, which the loading and unloading device must be assigned v / earth. All slideways in each row could be collapsible, be retractable or retractable without them, as in the case of the figure shown, with fixed slideways for could belong to one or the other series. Likewise, each side face of the frame could be a number of rotating shafts larger assign two.
