Product Description




4. Product Description
4.1 Application Range, Description

4.1.1 Overview
The WM modules WM6 | 35 | 60 | 120, when used in conjunction with the WM 22
evaluation electronics, combine to form a checkweigher for determining the weight
or completeness of products.

All WM modules offer a variety of interfaces. This enables smooth, centralized
integration of WM modules into existing or new quality assurance systems, for
100% traceability in production monitoring.

4.1.2 Machine Design
A WM module consists of the following design elements:
§ Weigher frame with control unit
§ Weigh cell
§ Indicator
§ Control electronics

Optional structural components include, for example:
§ Touch guard (optional)
§ Reject or sorting mechanism (optional)

Products are transported via a conveyor belt and weighed while passing over the
weighing belt. The weighing belt and the customer infeed and outfeed belts must
all have the same belt speed so that the parts to be checked are transferred
smoothly to the weighing belt and then moved away again.

The individual components are described in more detail below:

Weigher frame with control unit
Solid tower housing of steel, powder-coated, protection class IP 65.
The weigher frame is available in different heights so that you can implement
different transport heights. The desired working height can be adjusted in
increments of 50 mm, from 450 to 1100 mm (special heights available upon
request). Threaded leveling feet are provided for fine adjustment of the height.
The display and operating terminal is built into the control unit.

Weigh cell
Strain gauge weigh cells from Sartorius, characterized by the following features:
– Maximum precision and extremely short stabilization time
– Maximum stability, robustness and overload protection
– State-of-the-art electronics with digital signal processing for particularly effective
   filtering

Product Description




                                            Transport System
                                            The products are transported by the weighing belt.
                                            A conveyor belt serves here as the transport medium.
                                            The weighing belt is driven by a frequency inverter controlled, maintenance-free
                                            230 V AC drive motor. The force transmission is implemented by drive belts.

                                            Control Electronics
                                            The control unit is integrated into a powder-coated control cabinet that is accessible
                                            from the back or front depending on customer requirements.
                                            The terminals for the power supply, small control system, mains adapter and
                                            frequency inverter are also installed in the control unit.
                                            The main switch and the display and operating terminal are installed in easily
                                            accessible locations.
                                            The WM and X4 (optional) evaluation electronics are available for selection.
                                            The Start|Stop key for the transport medium is located on the top of the control
                                            cabinet.

                                            4.1.3 Functional Principle, Mode of Operation
                                            Weighing takes place automatically in a dynamic state (throughput operation) or
                                            static state (start-stop operation) without intervention by the operating personnel.
                                            The products to be weighed are transported to the weighing belt by a customer
                                            infeed belt. The weight value is determined as follows when the product crosses the
                                            weighing belt.

                                            The product nears the weighing section of the weighing belt. The product is picked
                                            up by the transport belt. The internally determined weight value changes from “0"
                                            increasing to a weight value “G."




                                            The product lies completely on the weighing belt. The value determined by the
                                            weighing platform is higher at this moment than the actual weight value of the
                                            product.
                                            This behavior is called overswing.




                                            The product is now transported by the transport belt over the weighing section. The
                                            continuously determined weight values are increasingly identical. This determined
                                            weight value corresponds to the actual weight value of the product.




                                            The product breaks the light barrier. The weight value determined at this moment is
                                            shown on the display of the WM indicator and output via the interface. At the same
                                            time, the classification outputs for lighter, heavier and equal are queried by the PLC
                                            and a potential-free contact is opened corresponding to the determined
                                            classification.
                                            This can then be processed further, e.g. for sorting control.

Product Description




                 Product distance

                 The next product nears the transport belt.

   Important!
      h
		Two products may not be conveyed at the same time over the transport belt and
   thus over the weighing section.
   In addition, a safety factor of 10% of the length of the weighing section should be
   added.

                 This is how you determine the product center-to-center distance:
                 The product center-to-center distance corresponds to the distance between the
                 product front edge to the product front edge or the weighing belt length + 10% of
                 the weighing belt length.

                 The product leaves the transport belt, the last determined weight value remains on
                 the display until the next weight value is determined and displayed.

                 The measurement process for determining the weight makes use of a load sensor
                 with a strain gauge.
                 The introduction of force takes place directly via the conveyor belt to the weigh
                 cell.
                 The weight force to be measured deforms the strain gauge. The resulting resistance
                 change is converted into an equivalent weight value together with a mass unit by
                 the evaluation unit of the WM indicator and shown on the display.
