In addition to the proven particle counting devices, elmor now also offers a weight dosing unit. With it, fine seeds, free-flowing granules or powders can be dosed very precisely in the gram range. The device of a specialized manufacturer can be combined for example with the elmor 800 packaging machine or the elmor filling carousel, or it can also be used as an independent dosing unit.

The patented process uses an ingeniously simple, maintenance-free and reliable dosing mechanism. With it, small portions can be staggered in a timely manner on a precision balance. For the variant used by elmor, this is a Mettler Toledo WMF industrial balance with a resolution of 1mg or 0.1mg (100 micrograms). An intelligent dosing algorithm promotes decreasing subsets at short intervals. As a result, the target weight is reached within a few seconds. The dosing tolerance is in the lower % range.

The special design of the dosing unit and the absence of vibrating feeder units prevent even inhomogeneous products from being dosed with virtually no measurable segregation or grain size selection.

The field of application of this dosing scale is found in the filling and packaging of fine seeds, granulates of all kinds such as micronutrients, pharmaceuticals, granular reagents, powdered cannabis products, ground hemp leaves and many more.

The increasing legalization of cannabis has led to a growing demand for our accurate seed counters and filling devices. As a rule, small piece numbers are usually to be counted, e.g. single grains or small amounts of a few seeds only. The elmor C1 seed counter is extremely suitable for this counting task, as it has been optimized for processing small to medium batches.

After counting the seeds need to be packaged. All possible packing materials are used, from simple PE Zip bags to custom-made paper, cardboard, plastic or metal boxes. The packaging operation is in most cases a time-consuming manual work, which is why many customers combine the seed counter with a filling carousel.

Thanks to the modular construction of the elmor carousel filling machine, practically all containers can be processed. By saving working time with the elmor carousel and thanks to the precise dosage with the elmor C1 seed counter, the investments can be amortized within a short time.

The elmor counters are normally used as batch counters. This means that a certain amount of a product must be counted, and then the machine is used for a next task. In the present application elmor multichannel counters were installed firmly in two production lines. The products – safety-related mechanical precision parts for the automotive industry – are fed continuously via a belt conveyor. Then they are counted, portioned and fed into a packaging machine. The system operates up to 7 x 24 hours. Thus, the elmor multichannel counting machines can be in continuous, unsupervised use for several months. This is only possible thanks to the unique sensor technology of the elmor counters. Whether in harsh and dusty industrial environments or in the laboratory with the finest products, the sensors retain their high precision and can be operated during months without cleaning and maintenance.
As a member within a worldwide just-in-time supply chain uninterrupted supply of products must be guaranteed. The entire system, including the counting and packaging part is therefore built redundant. The elmor 650 counting devices in turn are ideally suited for this task thanks to the robust sensor modules. At each machine 2 sensor modules are incorporated, each with 5 channels. In case of failure a module could be replaced within a very short time.

The very popular Rhinestones experience a boom as jewellery and fashion accessories. In addition, many textiles are decorated with stick-on stones (hotfix or hot glue rhinestones).

For the retailer, the exact dosage of these stones is quite difficult. The smallest stones may have dimensions of a few 1/10 mm and a weight of only a few milligrams. The weight of Hotfix stones varies due to tolerances in the amount of adhesive. The commonly practiced determination of a number of pieces based on the weight therefore leads – especially for small and hotfix stones – inevitably to incorrect values. Complaints from customers, inventory discrepancies or missing sales margins for the dealer are the result.

In an actual case, a customer has decided to count its stones with a PC controlled elmor C3 counting system. The elmor counters were originally developed to count plant seeds. Increasingly, the seed counters are also used for counting smallest mechanical parts – as well as rhinestones.

The elmor C3 can exactly detect small parts in the range of 1/10mm to more than 10mm. The control software allows to count total amounts or a predetermined number of pieces accurately and repetitively, for example 50 times 100 parts.

The small parts are an important sector of the customer’s product range. They can be processed with the standard conveyor bowl. Since very flat stones are present among these parts (thickness only a few 1/10 mm) the feeder bowl was equipped with the sorting element FS3. The FS3 is continuously adjustable in height and width. Thus stones next to each other as well as superposed stones can be eliminated from escaping so that only one stone after another leaves the vibrating bowl and is precisely detected by the highly sensitive sensor.

Caused by the vibrations of the conveyor bowl stones with small dimensions tend to charge electrostatically, which could lead to errors. With an ionizer the charges can be neutralized.

For large stones there is a risk that the cut edges being damaged during the conveying process. For this reason a conveyor bowl with polyurethane coating is used for stones larger than about 5 mm in diameter.

The data of all counting operations can be stored and exported for further use.
