CIE HS Project

重量分选应用于许多行业，其中质量与质量的确定有关。在大批量生产非常小的零件的情况下，问题变得更加复杂。测定质量所需的准确度和生产量要求都很高。这一要求在制药工业中很普遍，因为片剂和胶囊的质量至关重要。还有许多其他情况下，一个项目的质量可以被用作故障的指标，例如注塑组件中的空隙。任何质量测量系统在某种程度上都容易受到被测产品位置和方向变化的影响。对于高精度系统，这种效应会导致误差源以及吞吐量的显著降低。对于仅设计用于称量单一产品形状的系统，这可以通过根据被称量产品的特定尺寸定制处理系统来解决。此外，在部件交付引起的扰动之后，称量头稳定所需的时间将影响循环时间。为了在不影响精度的情况下最大化生产量，搬运机构必须能够在尽可能小的干扰下输送零件。由于零件形状、尺寸和材料的范围很广，除了定制解决方案外，几乎没有其他选择可以满足任何特定需求。HS项目的目标是开发一种具有成本效益的机器，以满足这一需求，并提供一个通用的解决方案。它将能够以高吞吐率对各种小形状和尺寸的物品进行称重和分拣。这将通过一种新颖的处理系统的应用来实现，该系统能够以非常一致的方式对各种形状、尺寸和材料进行单一化和进料。它还将能够处理与某些材料有关的污染问题。

Weight sorting is applied in many industries where mass is relevant to the determination ofquality. The problem becomes more complex in the case of very small parts produced in highvolumes. The accuracy required to determine quality is higher, as is the throughputrequirement.This need is prevalent in the pharmaceutical industry where the mass of tablets and capsules isof critical importance. There are also many other cases where an item's mass can be used asan indicator of failure, voids in injection moulded components for example.Any mass measurement system will be susceptible, to some degree, to variations in theposition and orientation of the product being measured. For high accuracy systems, this effectcan cause a source of error as well as a significant reduction in throughput. For systemsdesigned to weigh only a single product shape, this can be addressed by tailoring the handlingsystem to the specific dimensions of the product being weighed.Furthermore, the time taken for the weigh head to settle after the disturbance caused by thedelivery of a part, will affect the cycle time. In order to maximise throughput withoutcompromising accuracy, it is essential that the handling mechanism can deliver the part withas little disturbance as possible.Because of the wide range of part shapes, sizes and materials, there are few options availableto meet any particular need other than a bespoke solution.The objective of the HS project is to develop a cost effective machine to meet this need withone generic solution. It will be capable of weighing and sorting a wide range of small shapesand sizes at high throughput rates. This will be achieved by the application of a novelhandling system capable of singularising and feeding a wide range of shapes, sizes andmaterials in a very consistent way. It will also be capable of dealing with contamination issuesassociated with certain materials.
