^w Transport device, especially for screen printing machines "

The invention relates to a transport device, in particular for screen printing machines, for transporting conical and / or cylindrical and / or differently shaped Objects (hollow bodies), with at least two in parallel Distance adjacent to each other, the objects to be moved in prism-shaped receptacles holding conveyor chains, their opposing chain links provided one behind the other at a distance, partly as upwardly projecting drivers each with two differently sized support or contact surfaces running at an angle to the plane of movement of the chain are.

The known transport devices of this type have the disadvantage an inadequate recording capacity, as it is only suitable for objects with a certain cross-sectional area and a Kreuzachnittsforn are designed. In the known gate directions In a disadvantageous way, only objects can be bit cylindrical Record cross-section. Furthermore, these devices have the disadvantage that conical objects only occur in Pressure range τοη pick-up and centering devices and their surface can be set up on the printing plane.

The object of the invention is to create a transport device with which the objects can be avoided while avoiding the previous deficiencies with a large tolerance range in the cross-section size can be transported in a simple and safe manner. Another object of the invention is seen in that in particular conical objects can be moved in an aligned position for printing.

According to the invention is a transport device according to the opening mentioned type characterized in that in each case for an object to be moved the same size and / or recordings of different sizes, such as recording prisms opposite and all recordings with their conveyor chains to set up the highest longitudinal edge of the objects in a horizontal plane (pressure plane) are provided pivotable.

In a preferred embodiment, opposite receptacle prisms of the same size and / or different sizes on a common, at right angle \ Arrange the central axis running in the longitudinal direction of the chain.

It is preferred that the recording prisms around a common, in Chain longitudinally running horizontally «axis can be pivoted and thus to be arranged adjustable in height and dia Aufa & hne-.

The conveyor chain and the top edge of the casing of the objects are adequate Freedom to print the objects in a screen printing machine is given.

Another advantage is the opposing arrangement of differently sized receiving prisms and the pivoting the same seen, thereby favorably conical or similar objects aligned with the printing plane or printing station can be supplied.

The pivotable design of the receiving prisms enables the introduction of different conical objects, their Shell length edge set up in each case in a horizontal plane - this enables the conicity to be compensated for.

By shifting the length of a chain, it is possible to accommodate the opposing, differently sized receiving prisms to be arranged in such a way that prisms of the same size are opposite each other, whereby in an advantageous manner in the erfihdungsgemässen Transport device both conical and cylindrical as well as other objects in the aligned position of the Printing station can be fed.

The drivers 12,13 are with their bearing surfaces 16,17 to arranged that in each case two identical support surfaces 16 or 17 result in a receiving prism 18, 19 and thus alternately differently sized receiving prisms 18, 19 lying one behind the other extend in the chain area; All drivers 12,13 are arranged with their bearing surfaces 16,17 so that at least two different sizes and alternately one behind the other arranged receiving prisms are formed.

The contact surfaces m 16, which are kept shorter in length, for example, result in adjacent,. Arrangement of a smaller receiving prism 18 for objects with a smaller cross-section than the bearing surfaces 17, which are larger in length and are arranged adjacently and which form a larger receiving prism 19 for objects 15 or areas of objects that are larger in cross-section than the objects 14 (cf. , 4.6).

The drivers 12,13 are according to the embodiment according to Fig. 1, 4 and 6 formed congruent and all with the same support surfaces 16,17, namely with a support surface 16 and a bearing surface that is larger in length than this 17 equipped.

These drivers 35, which are variably arranged on the conveyor chains 34, form opposing receptacles of the same size and / or different sizes for inserting the objects to be moved 31 9 32, 33 * For example, three carriers 35 provided offset to one another engages the object 31, 32, 33 to be moved at three points (surfaces) - it is preferred to arrange the two outer carriers 35 in a line running transversely (at right angles) to the direction of movement of the chain and the middle Provide drivers 35 at a distance from the outer drivers 35 and thereby to be arranged in the direction of chain movement behind or in front of the outer drivers 35. Furthermore, all drivers 35 each forming a receptacle can be provided at a distance from one another in parallel lines.

The arrangement of the carriers 35 forming the receptacles to one another can be selected as desired and in accordance with the ones to be moved Objects 31,32,33 be executed. In the case of two parallel conveyor chains 34, four drivers 35 each form a receptacle, with three or more parallel running conveyor chains 34 at least three drivers arranged offset to one another 35 result in a receptacle for the objects 31, 32, 33.
