Problems solved by technology

As a result, the size of the gap between container and closure cannot be reliably determined on the outermost edge of the closure
Identification of an overturned closure in a container is also problematic

Embodiment Construction

[0020] The containers 12 are conveyed to the conveying device 20 via the inlet 28 . The container 12 has already been filled with a product, for example a liquid medicine, at a preceding, not shown, workstation and closed by a closure 14 . exist figure 1 The device shown in FIG. 2 is used for testing the closure area or for testing the size of the gap formed between the container 12 and the closure 14 . The conveying means 20 is designed, for example, as a conveying star. The transfer means 20 has on the outside a receptacle 22 in which the container 12 can be fixed. The transfer means 20 rotates clockwise. Thus, the container 12 first arrives in the sensing range of the sensor 18 for ascertaining the height profile. The sensor 18 for ascertaining the height profile is arranged above the transport path of the containers 12 . By way of example, the sensor is configured in the form of a line and at least partially covers the surface of the closure 14 which closes the contai...

Abstract

The invention relates to a device and a method for testing a closure (14), wherein the closure (14) closes a container (12), wherein an analysis unit (23) is provided for ascertaining a quality criterion (40, 47), in particular the size of the gap between the closure (14) and the container (12), wherein at least one sensor (18) for ascertaining the height profile of the closure (14) is provided, Wherein, at least one output signal of the sensor (18) is sent to the analysis and processing unit (23), and the analysis and processing unit obtains the quality criterion (40, 47).

Description

technical field [0001] The present invention relates to devices and methods for inspecting closures. Background technique [0002] The invention proceeds from a device and a method for checking closures of the type according to the independent claims. In pharmaceutical manufacturing it is common to place closures on containers such as bottles. In a further step, the closure and the container are connected by means of a cap. A gap may form between the closure and the container. The height of this gap is critical for pharmaceutical production, since the product can be contaminated in the worst case due to an excessively large gap. Accurate verification of said gaps is important since containers with small gaps can still be accepted to avoid unnecessary rejects. [0003] A device of this type is already known from WO 2012 / 061441 A1. In this case, the closure area to be detected enters the path formed by the laser and the corresponding receiver. The laser beam passes throu...
