Problems solved by technology

[0003] The inspection and ejection unit described has proven itself in practice; however, it has been found that at higher transport speeds (i.e. from about 30,000 parisons per hour) the parisons shake or vibrate when entering the star wheel, so that The camera may not be able to take a clear picture of the parison passing by or below it, and therefore a defective parison may not be identified

Embodiment Construction

[0030] exist figure 1 A partial view of an inspection unit is shown in , wherein the attachment 10 according to the invention is arranged in the inlet region of the star wheel 1 . The parisons 2 are conveyed via a conveying device 4 , ie generally a conveying rail, to the star wheel 1 of the inspection unit and are taken up there by corresponding transport recesses 6 of the star wheel 1 . The conveying device 4 can additionally be switched to other parison sizes via the adjusting device 5 also shown.

[0031] The attachment 10 according to the invention is usually arranged very close to the entry point of the parison 2 into the star wheel 1 in order to stabilize as quickly as possible for a downstream (relatively close) arranged camera (not shown) of the inspection unit. the parison. As can be seen, approximately two parisons 2 pass through the attachment 10 at the same time. The attachment 10 is arranged by means of a mounting section 15 and corresponding fastening means o...

Abstract

The present invention is directed to a device for immobilizing preforms (2) for plastic containers, in particular PET bottle preforms, in the inlet region of a driving device (1) of an inspection unit, comprising an attachment part (10) which at least has a first functional section (11a) (11a) is arranged downstream of the first functional section (11a), wherein the first functional section (11a) in particular isolates vertical disturbing movements of a preform (2) taken over by the entraining device (1). In such a way that the second functional section (11b) engages with the preform (2) into a substantially form-locking guide engagement, which effects a complete immobilization of the preform (2).

Description

technical field [0001] The invention relates to a device for stabilizing a preform of a plastic container, in particular a preform of a PET bottle, in the area of ​​the inlet of an inspection unit and possibly an ejection unit, such as a star wheel. Background technique [0002] A corresponding inspection and ejection unit for such parisons is known, for example, from EP 2 845 715 A1. The inspection and ejection unit comprises a drive device in the form of a star wheel, which receives and conveys the parisons from the conveying device to the inspection and ejection unit and always transfers a part of the parisons to the removal device . The inspection and ejection unit also comprises a detection device in the form of a camera by means of which defective parisons in the star wheel are identified, and an ejection device by which parisons identified as defective are The blank is removed from the star wheel. [0003] The inspection and ejection unit described has proven itsel...
