CX Counter Module

<< all products

The elmor CX counting module is a piece-counting device without its own operating unit. It is often used as a dosing unit in packaging machines and is controlled directly via the machine’s PLC. One or more CX modules can be integrated in parallel.

Applications

The most important application of the elmor CX counting module is precise piece-by-piece dosing of small parts, for example seeds, mechanical precision parts, precious stones and gemstones, and similar products. Operating several modules in parallel makes it possible to equip even high-speed packaging machines with piece-count dosing.

In addition, dosing systems for mixtures of different components can also be implemented with the elmor CX.

Design / Construction

The elmor CX consists of:

• Counting head with conveyor unit and part sensor
• Electronics unit for complete remote PLC control

The counting head has an open design and is very narrow. This allows multi-head dosing systems to be built compactly and clearly even where installation space is limited.

Performance range

The technical specifications largely correspond to those of the elmor C1 seed counter.

• Countable parts: 0.2 to 18 mm in diameter
• Cylindrical parts: up to 20 mm in length
• All sizes are counted using the same adjustable feeder bowl. Additional feed hoppers are not required.
• For special shapes or extreme dimensions, optimized trays and adapted sorting elements can be used.

Dosing accuracy

The conveying speed can be reduced shortly before the target quantity is reached. This ensures high dosing accuracy.

Example values (balls Ø 2 mm):

• Counting capacity: approx. 50,000 pcs/h
• Counting error: < 1 ‰

Control and interfaces

Counting quantity and counting modes are specified by the PLC.

Interface signals

• Digital signals (24 V DC): Run/Stop, Slow, counting pulses (output)
• Analog signals (0–5 V): conveying speed, sensor sensitivity (provided via PLC or external potentiometers)
• Multiplex function: With the multiplex function, a single analog value is sufficient to set all analog parameters.

Conveyor bowls

The parts to be counted are transported in a vibrating conveyor and are singularised by means of a sorting element. Both the conveyor bowl as well as the sorting element can be selected among different variants , depending on the properties of the product to be counted.

A) Standard conveyor bowl made of anodised Aluminium with universal – sorting element FS0. FS0 is manually adjustable for all part sizes from 0.1 to 18 mm in diameter.

B) Special sorting elements instead of FS0:

• FS1, manually adjustable, optimised for cereals, rice, paddy and products of similar shape and size
• FS2: manually adjustable, optimised for corn, soybeans, peas, beans and products with similar shape and size
• FS3: fine-drive adjustable in height and width, for very flat seeds or flat mechanical parts with the following dimensions: width: 0.5 to 10 mm, height: 0.5 – 8 mm, maximum length: 20 mm

C) Special conveyor bowl with additional lateral opening for mechanically eliminating of accompanying substances, suitable for corn, cereals, soybean, paddy, etc. The height of this opening can be adjusted from 0 to 5 mm and allows unwanted accompanying substances laterally
be sorted out. Not suitable for parts smaller than 1 mm in diameter. Can be used with sorting elements FS0, FS1, FS2, or FS3 combined.

D) To meet the needs of various industries, the conveyor bowls can be made ​​of other materials . These bowls are for example extremely impact resistant or correspond to the rules of the FDA, etc. Such trays can be made ​​from various basic materials like Titanium, PEEK, Polyamide and others.

E) The standard aluminum bowls can be treated or coated in order to satisfy specific requirements. With increased mechanical stress or when in contact with food, the surface can be hard anodized. A hard coating of nickel has a high surface hardness and is FDA approved, Polyurethane (PU) coating permits rapid transport of heavy mechanical parts and prevents noise and wear. Again, FDA approved materials can be used.

F) Feeder Bowl with vertical outlet: Short cycle times are possible, as the seeds leave the bowl after a short run time. Advantageous when many different lots must be processed, often used for the fast 1000 grain weight measurement. Used for seeds which can be easily singularised like Crop, Soy, Corn, Canola etc. The seeds should have a diameter of 2 mm or more. Volume 0.8 litres, or about 2500 kernels of Corn.
