Method and apparatus for monitoring the deviation of an object from a sequence and corresponding control system

Abstract

The method involves determining the time course of an actual value of a size dependent on load of the rejection system, and comparing of the time course of the actual value with the time course of the desired value of the size dependent on load. The size dependent on load comprises a deflection of a contact element of a pusher of the rejection system. An independent claim is also included for a device for checking rejection of an object from sequence of objects through rejection system.

Description

technical field

[0001] The invention relates to a method for sorting items by a sorting system for checking a sequence of items. Background technique

[0002] In the sequence of articles conveyed by the conveying element, items to be sorted, such as defective articles, are usually identified by means of an inspection device and then sorted out of the sequence of objects by the sorting system. These items can be, for example, containers to be filled in the beverage industry. In order to carry out a so-called rejection control, a light barrier is often provided, which is located downstream of the sorting system and checks whether the container has actually been sorted. This inspection is important because otherwise damaged or defective items may be sold.

[0003] It is conceivable that there are certain situations in which a light barrier arranged after the sorting system cannot detect defects, ie incorrectly performed item sorting. Contents of the invention

[0058] figure 1 An exemplary sorting system is shown. in addition figure 1 A sequence of items is shown, including items to be sorted, such as defective items 101 , and items not to be sorted, such as non-defective items 102 . In a conveying direction 109 , the sequence of articles is conveyed on a conveying element 103 , for example a conveyor belt. figure 1 Also shown is a sorting system 106 comprising pushers defined by electronically controlled linear motors.

[0059] By means of the pusher, in particular by means of contact elements of the pusher, such as pusher plates, the objects 101 can be sorted from the sequence of objects and arranged on the conveying elements 104 and 105 respectively from the positions from which they can be ejected . Arranged upstream of the sorting system 106 in the conveying direction 109 of the sequence of items is a sensor 110 which is realized and / or configured such that it can identify the items 101 to be sorted. The sensor 110 may be, ...
