Clear Film Detection

How can I detect a web of clear film without using a reflector?

Divergent (wide-beam) diffuse mode photoelectric sensors are well equipped to detect transparent objects, such as clear films, bottles, glass, and packaging. This eliminates the requirement of a reflector or thru-beam. However, as a rule of thumb, the sensing distance is reduced by about 50% of the sensor’s specified maximum distance due to inefficiencies of the transparent object. This usually translates to sensing ranges of 25-50 mm (1-2 inches). Examples of sensor families that can be used in this case are the KT9 and KT11 series.

Ultrasonic sensors monitor sewage sludge levels

Monitor sewage sludge levels which Pepperl-Fuchs Ultrasonic sensors

Waste water treatment produces enormous amounts of sewage sludge on a daily basis. This waste product has to be processed or properly disposed of. Either way, it is necessary to load the sewage sludge into appropriate transport containers.

Ultrasonic sensors monitor the process to prevent overfilling of the containers. Fill level is monitored by an ultrasonic sensor and output as an analog value. When the maximum fill level is reached, the sensor delivers an additional switching signal to stop the flow of the material.

Benefit
Prevents the overfill of the container.

The Clever Mounting Aid for Workpiece Carriers used for Inductive Identification

Pepperl Fuchs develops mounting aid to deal with transport change of direction

At some conveyor lines, the transport direction changes by 90°. The work piece carrier has an IDC-15-1K data carrier (lateral reading and writing at the roller conveyor with IVH-M1K). If the direction of travel of the work piece carrier changes by 90°, the data carrier is no longer in a potential read/write area. In the past, a complicated mechanical system (lifting cylinder) was used to place the work piece carrier so that it could be read and written with a 90° turn.

Pepperl Fuchs developed a holder for the IDC-15-1K data carrier that permits reading and writing from two sides.

The use of the special holder saves costs because now only one inclined data carrier is required. The technically complicated mechanics of the lifting cylinder are no longer required because the work piece carrier no longer needs to be turned.

RFID Supplies Reliability, Flexibility and More Security

Challenge
In most applications, radio-frequency-identification (RFID) systems are used to store product and process data on, or retrieve it from, a special RFID tag using wireless technologies. Power to operate the electronics in the tag comes from the RF energy of the interrogating transmitter. When powered, the tag transmits the programmed identifying information to the receiver. But if you look at RFID tagging on a more-fundamental level, it’s essentially a smart proximity sensor.

Application Solution
A proximity sensor detects the presence of a piece of metal and knows that a pallet has arrived at that location. Likewise, an RFID system also detects the arrival of a pallet. Except an RFID system can also determine what type of part is on that pallet by reading the identification code programmed into the tag. This does not mean to suggest RFID beats proximity sensors for all possible applications, however, applications that use a collection of proximity sensors to read a code block — basically a piece of metal with a hole pattern — should seriously consider an RFID upgrade. Not only does RFID provide flexibility in the event a system must expand, it also gives more security and reliability.

Benefit
Error detection built into the RFID read operation reduces the chance of a read error. RFID also has a greater reading distance than the sensing range of a proximity sensor of comparable size. For example, an 18-mm extended range sensor has a nominal sensing distance of 12 mm, while an 18-mm RFID read/write head can read tags at 40 mm or greater. It’s easy to place the RFID read head safely out of the way of a moving pallet.

RFID Accelerates Tool Exchange on Mobile Equipment

The simple, safe, and fast exchange of tools is an important sales feature for mobile equipment

Challenge
Depending on the work at hand, mobile equipment tools are frequently changed. This must be accomplished quickly and safely. The goal is to protect tools from damage by automatically adjusting pneumatic operating parameters to increase yield. Unproductive exchange times are shortened and lead to improved time management.

Application Solution
Inside the cab the RFID interface is connected to the onboard CAN bus of the equipment. A compact 18mm read head is mounted at the front of the excavator arm and is connected to the RFID interface using a shielded cable with M12 connection. RFID tags are flush mounted in each attachable tool or bucket and are well protected from the elements by the steel of the tool. The tags carry a unique ID, allowing the mobile equipment to determine the correct pneumatic operating data for the tool. Once the tool has been mechanically linked, the RFID tag is automatically read and the correct parameters are set, assuring proper operation and preventing damage.

Benefit
Fully automatic tool exchange configuration process for highest machine reliability.

Safe Stack Turners and Logistics Systems in the Printing Industry

Modular safety system exploits rationalization potential

Due to increased printing capacity, automation of logistics processes is critical. Printed sheets must arrive at the feeder and be delivered without process delays. With every unnecessary machine stop, the printing and ink parameters must be reset and optimized, adding time, waste, and cost to the process.

Application Solution:
All operator-accessible points on the machine are monitored with light barriers and light grids. Pepperl Fuchs SLA29 sensors are permanently active safety light barriers. Their detection range is extended by means of adjustable mirrors as far as this is useful. Depending on the risk potential, SLC30 safety light curtains may be required as an option for hand protection.

Benefit:
Previously, Krifft & Zipsner had used four different switching devices by two manufacturers for every machine, for example, the SLVA-4K evaluation device for the permanent light barriers and the SLVA-8K for the muted light barriers. All of these functions are now performed by the Safebox in an easier and more rational way.

Quality in Manufacturing: Double Sheet Detection for Plastic Plate and Film Sheet

Double Sheet Detection

Cost effective processing of plastic plates and film sheets is very important in manufacturing print products. Quality requirements for high gloss products are very demanding. Even the smallest scratch on the surface or manufacturing steps that are not completely clean can result in waste. Plastic plates and film sheets are separated from a stack into individual units for further processing. Before the individual plastic plates or film sheets are cut to size, a check must determine that only one plate or sheet has been supplied. If not, the equipment can be damaged and the material will be unusable. Double sheet detection increases equipment life and minimizes material waste.

The Solution:
The Pepperl+Fuchs UDC-18GM-400-3E3 ultrasonic double sheet detector checks for the presence of an item before it reaches the blade. The presence of more than one unit, due to static electricity or other reason, triggers an alarm. The UDC-18GM-400-3E3 reliably identifies the presence of no sheet, single sheet, or double sheet, ensuring reliable, quality processing.

Double sheet detection has previously been triggered by a simple mechanical switch. Measurement that involves contact can mar the high-gloss plates or sheets. The change was made to no-contact ultrasonic detection to increase quality. Scratches are now a thing of the past. The Pepperl Fuchs UDC-18GM-400-3E3 ultrasonic double sheet detector is designed for a wide range of applications and is able to check all materials, from transparent film and thin film sheets to plastic plates 2 mm thick. For thicker media, such as sheet steel, the UDCM-30GM-085-3E3 ultrasonic double sheet detector is available.

Chipboard Detection in Dirty Surroundings

Ultrasonic sensors used in rough environment

The chipboard (particle board) turner from BHT Bau- und Holztechnik Thüringen GmbH requires a detection system that can reliably detect whether a compartment is occupied or not, even in dirty and dusty surroundings.

Application Solution:
The solution consists of approximately 30 ultrasonic sensors UB500-30GM-E5-V15, which are installed horizontally between the roller conveyors. The attached sound deflector UVW90-M30 deviates the ultrasound upwards and the sensor detects whether a compartment is occupied or not. Dust and dirt cannot settle on the active sensor, and falls down through a slot in the sound deflector.

Benefit:
Using the ultrasonic sensor with attached sound deflector helps prevent error signals and downtime caused by contamination.

This is an application solution from Pepperl+Fuchs.

Side Loader and F99 Inclination Sensor

The combination of the HUBTEX multi-way side loader and F99 Inclination Sensor increases loading efficiency.

If lift heights are very high, or when the driver is unable to see the exact fork inclination in the rack, the F99 inclination sensor from Pepperl+Fuchs can easily solve the problem.

It can easily manage bar stock material, sheet packs, particle board, tools, cable drums, rollers, and oversized pallets whether they are located in narrow-aisle racking installations or freely accessible indoor and outdoor areas. The F99 inclination sensor is mounted to the mast of the electric multi-way side loader and transmits the fork inclination to the HUBTEX Information Terminal in the driver’s cab. The driver in the cab can select the predefined lift height at the touch of a button and store up to 99 positions. He is aware at all times of the exact fork inclination.

The inclination sensor and the HUBTEX Information Terminal speed up the storage and retrieval of the goods in the racks and the loading and unloading of trucks. The system guarantees increased levels of safety at work and ensures that goods are not damaged.
