SMC Pneumatic Products Used in Conveyor Applications

Conveyors

SMC provides the ideal breadth of products for complete systems and multiple applications. This complete array of products results in SMC pneumatic systems that are capable of specifically meeting infinitely diverse food packaging and processing requirements such as:

  • continuous 24/7 operation,
  • stringent hygiene regulations,
  • continual wash down, and
  • extreme temperatures.

Further emphasis has been given to developing products that address two industry requirements:

  1. providing maximum operator health and safety, and
  2. addressing energy costs.

The sampling of products noted below have been included to illustrate how SMC continues to grow to meet the ever changing demands of the food packaging and processing industry.

SMC Actuators -- Designed with Packaging in Mind

Compact Guide Cylinder, Series MGP

The Series MGP, compact guide cylinder contains dual guide rods and single bore in a compact body. The guide rods offer two primary advantages -- non-rotation and dramatic lateral load resistance while the large tooling plate is ideal for pushing or lifting larger objects, or attaching custom tooling in a stable, secure manner.

With its dramatically higher load resistance, the MGP is ideal for conveyor stopper or product pusher use.

Features that offer improved performance include:

  • End Lock type (holds home position even if air supply is removed)
  • Air Cushion type (absorbs almost 3X kinetic energy of bumpers with less noise, vibration)
  • Heavy Duty type (oversized guide rods increase lateral, eccentric, and impact load)
  • High Precision Ball Bushing Bearing type (offers ±0.01° non-rotating accuracy)

For example, included in the design is a rubber rod wiper to keep potential contaminants from penetrating inside the cylinder. The rod wiper and seals are available in either NBR or FKM materials. These enhancements increase the life of the cylinder by up to 5x. Further, the smooth exterior surface reduces the potential number of particle entrapment areas.

Options which make the CG5/CJ5 an optimal choice for food processing applications:

  • Stainless steel body
  • Rubber Rod wiper (keeps contaminants out)
  • Smooth exterior surface
  • NBR or FKM material options for the rod wiper and seals
*The CJ5 is the small bore version and is available in 12mm and 16mm bore sizes. The CG5 is available in bore sizes from 20mm to 100mm.

Multi-Position Cylinder, Series MPC

The SMC multi-position cylinder, Series MPC, addresses application needs where an infinite number of adjustable stroke positions are required. Accuracy in the MPC is driven by a 4~20mA or 0~10VDC input signal to automatically adjust the actuator stroke. Once the MPC reaches the desired position, it is pneumatically locked until the input signal is changed. To address the specific needs of food processing and packaging applications, the MPC has an IP65 rating so it can be used in a wash down environment.

Features which make the MPC Series an ideal low cost pneumatic alternative to electric actuators:

  • MPC is a Cylinder + Solenoid Valve + Linear Sensor + Controller all in one unit
  • Requires only an air supply for the appropriate input signal
  • Easy adjustment for dynamic applications
  • IP65 rated for wash down environment

SMC Valves -- The Heart of a Pneumatic System


Clean Style Valve Manifold, Series SY Type

Developed for the food and beverage industries, the clean style manifold has been designed to meet the specific needs of the food processing and packaging industry. For example, the SY type manifold features an IP69K rating, thus designed to withstand high pressure and steam cleaning. Further clean style elements are throughout the structural design. The manifold allows for the installation of valves outside of a protective panel and closer to actuators for better control and less piping. For applications with restricted space requirements, this compact solution allows for both high and medium flow rate valves on the same manifold. Finally, there are no gaps between the stations so that contaminant will not get trapped in those areas.

Design elements that make the clean style valve manifold ideal for the food and beverage industries include:

  • IP69K rating (can withstand high pressure and steam cleaning)
  • Protective panel
  • Smooth, gap free design

These features allow for customization for a variety of automated manufacturing operations. The SY Series addresses the need for flexibility required of the food industry with its' ability to change the valve's direction, size and piping, as well as the bottom port entry. The ease-of-use of the SY is found in its' broad range of operating air pressure and customization which allow for simplified replacement valve inventory management, as well as its' "Plug and Play" concept for building pneumatic and electrical connections in the manifold.

Options within the solenoid valves that make the Series SY an energy efficient option for dynamic food and beverage applications include;

  • Ease of customization with narrow body and improved modularity
  • Ability to change valve direction, size and piping

The VFN valve series has been constructed from an engineered plastic PPS (Polyphenylene Sulfide) body which provides high temperature and chemical/corrosion resistance for use in wash down applications. Suitable for use in a steam environment, the VFN valve utilizes an EPDM duckbill exhaust protector check valve which allows exhaust air to escape and prevents wash down particles entering into the valve body. To further assist in the wash down environment, the 12mm stainless steel connector is part of the VFN construction to ensure water proof sealing. Finally, the valve has low power consumption for compatibility with an AS-i Bus system.

Features that make the NAMUR Mount Hygienic valve a design fitting for food packaging and processing:

ZP Vacuum Cups
Vacuum Saving Valve, Series ZP2V

The SMC vacuum saving valve, Series ZP2V provides energy conservation, increased efficiency, and simplified piping. Energy savings is obtained as the ZP2V restricts vacuum flow when a workpiece is not in place. Next, efficiencies are gained in applications that require multiple types of parts to be held. Utilizing many vacuum pads and one vacuum generator, the vacuum flow will be restricted to the pads that are not used thus allowing the holding pads to function properly. Finally, the ZP2V eliminates the need to switch operation when changing work pieces; thus simplifying the control circuit and piping.

Features of the vacuum savings valve, Series ZP2V, that help to lower production costs:

  • Restricts vacuum flow when a workpiece is not in place
  • No need for switching operation when changing workpieces
ZP2V Series
Non-Contact Cyclone Pad, Series XT661

The non-contact Cyclone Pad, as the name implies, offers non-contact workpiece holding. This Series, XT661, is ideal for holding workpieces with an uneven surface finish or viscous surfaces. For use with paper packaging supplies, for example, the non-contact cyclone pad uses air from the supply port which is ejected from a nozzle to create a whirlwind flow. Inside the cylindrical whirlwind flow, a vacuum is created. The flow creates an air layer between the workpiece and the unit while the generated vacuum holds the workpiece.

The non-contact cyclone vacuum pad is idea for applications where the workpiece is:

  • Sensitive to scars of suction traces (liquid crystal glass)
  • Porous (paper, cardboard, lumber, etc)
  • Thin (film, copper film, etc)
  • Filled with holes (substrate)
XT661 Series
