Embodiment Construction

[0295] figure 1 A schematic side view of a system for producing a bundle of separated round elongated elements (3b) is shown. The system comprises means (10) for inspecting a circular elongated element (3). Initially, molten glass (103) flows over a danner tube (102) mounted on a motor (101). Simultaneously, motor (101) rotates Danner tube (102) constantly. The motor (101) and danner tube (102) are inclined such that the molten glass (103) reaches the lower end of the danner tube (102), where a tube of molten glass (103) is formed. The tube of molten glass (103) is cooled and at a specific location (104) the tube of molten glass (103) solidifies and forms a glass tube, ie a circular elongated element (3). The cured glass tube is stretched by a stretching unit (2) comprising two rollers (21, 22). At a position between the point (104) where the molten glass solidifies and the stretching unit (2), the glass tube is inspected by the device (10) detailed in the figure below, th...

Abstract

The invention relates to a specific device (10) for inspecting a circular elongated element (3), such as a continuous glass tube produced by the Danner process. Furthermore, a particular method for inspecting a circular elongate element (3) is described herein. According to the invention, specific devices (10) and methods are used to produce separate circular elongate elements, such as specific bundles (3b) of glass tubes. These bundles (3b) can be used to produce pharmaceutical packaging or technical glass.

Description

technical field [0001] The invention relates to a specific device for inspecting circular elongated elements, such as continuous glass tubes produced by the Danner process. Furthermore, specific methods for inspecting circular elongated elements are described herein. According to the invention, specific devices and methods are used to produce specific bundles of separate circular elongated elements, such as glass tubes. These strands can in turn be used to produce pharmaceutical packaging or technical glass. Background technique [0002] For quality assurance, round elongated elements are usually inspected during or after production. If a defect is detected, the product or intermediate product may not be further processed. Examples of inspection devices are described in DE 10 2011 113 670 A1 and DE 10 2016 114 190 A1. Typically, during inspection, the inspected circular elongated elements are rotated; however, they do not move relative to the camera. [0003] The widely...
