This 3-way drop-off switch with flap mechanism and pneumatic actuation is used where good parts need to be separated from start-up/reject parts and quality control parts. It can also be used as a distribution switch at the end of a conveyor section to fill three containers sequentially.

This type of switch consists of a rectangular housing in which a changeover flap is attached to each outer edge. This flap can be pivoted into two positions, thus directing the conveying flow in different directions. Depending on the combination of flap positions, the three outlets are activated. The switching flaps are made of stainless steel as standard, but can also be manufactured from plastic (POM) if required. This is particularly important for smaller parts to keep any gaps as small as possible. The switching speed between the end positions is between 1.0 and 1.5 seconds with this type of drive. Therefore, this switch is particularly suitable for the targeted distribution of parts flows or as a quality control switch. Like all MTF Technik switches, this type is completely custom-designed and engineered. The switch can be integrated into all common injection molding machines or die-casting machines. For this purpose, the hopper, the connections to the machine frame, and the geometry of the discharge chutes are adapted to the specific application. Furthermore, this type of diverter can also be mounted at the discharge of conveyor belts or other feeding devices. Depending on the product range, the diverter valve, the hopper, and the discharge chutes can be manufactured from structured stainless steel sheets to prevent part adhesion. Special non-stick coatings can also be applied if required. Likewise, the discharge chutes can be equipped with transparent covers, inspection hatches, etc., according to customer specifications. In addition to the geometric adaptation, the electrical interface is also designed according to customer requirements. Depending on which interfaces and signals the production machine or existing control system has, the switch is designed accordingly.
