PTX Multi-Loader - Automatic Parts Loader

Versatile High-Speed Parts Loading Systems for Increases Productivity

PTX-Pentronix has developed an automatic high-speed parts loading system that will load a variety of parts from a press or feeding machine onto saggers, boats or trays. Designed to load parts one at a time, at speeds of up to 60 parts or rows per minute (in special applications up to 100 per minute). The Multi-Loader is of electro-mechanical design and consists of an indexing conveyor to advance the tray, a robot arm to pick and place the parts, a microprocessor based controller to coordinate the machine operation and operator control panel.

Product Application

Multi-Loaders are capable of many types of assembly operations. Virtually any part can be loaded quickly and efficiently with optimal density packing. For example, triangular objects can be staggered for maximum density. The Multi-Loader is also adaptable to other manufacturer's equipment.

Operations and Controls

• Microprocessors control all functions of the Multi-Loader. A master controller integrates the entire system, insuring high reliability and repeatability.
• Tooling consists of pneumatic/mechanical grippers or vacuum pickup devices and conveyor guides as required for the special applications.
• The conveniently located control panel contains all necessary controls for ease of set-up and machine operation.
• Sensors control indexing conveyor functions and verify that, 1) the tray is positioned for loading, 2) the tray is full, and 3) the conveyor is full. Also a message display on the control panel will indicate specific faults and their location. Optional signal can be sent to a remote station to shut off the parts source.

Pick-up Heads

There are two types of pick-up heads available on PTX-Pentronix Multi-Loaders.

• The Vacuum Wand is attached to the robot output shaft and picks up a row of parts for edge or flat loading applications.
• While the Carrier Assembly, with either a vacuum or carrier head, is able to pick-up and place one or more parts at a time.

Equipped with a sensitive parts pick-up head (pneumatic vacuum or mechanically operated) a part or row of parts, that have accumulated in a track are picked up directly from the conveyor and placed in a sagger, boat or tray. Parts are handled only once, minimizing the possibility of damage. The electro-mechanical robot with pick-up head and gripper is designed to pick parts up from the conveyor one at a time, or a row at a time. It then moves the pick-up head through a programmed arc for placement of the part in a pre-selected position in a sagger, boat or tray.

Indexing Conveyor

The conveyor holds up to three 12" saggers and is designed to automatically move saggers from an optional magazine to the load position.

As saggers are filled they progress to a removal point. If not removed within a preset time, a flashing light will be energized and the Multi-Loader will shut down. If interlocked with the feeding machine, the entire system can be shut off.

The Multi-Loader can be integrated to systems that move loaded saggers or trays onto a customer's automatic conveyor system.

Features

• Ease of Operation - Operation and set-up is uncomplicated and explained in detail in the Instruction Manual provided with each Press. Drawing, parts lists, nomenclature, operation procedures and a trouble-shooting guide is also included.

• Message Display/Control Panel - Intelligent display/control panel offers ease of set-up and operation. Display also indicates specific faults and their location.

• Adaptable - Design versatility to meet your applications.

• Double Sealed - All moving parts are double sealed to minimize wear due to abrasive materials.

• Portable - Free standing for easy relocation and easy access to press or supply machine.

• Part Changeovers - Simple and quick, involves replacement of a pick-up device, conveyor guides and actuation of programmed changes via control panel.

• Construction - Rugged welded and cast construction insures precise alignment and a high level of durability.

• Maintenance - Modular design insures simple and rapid replacement of parts with minimal downtime.

• Lubrication - Oil bath lubrication is provided for gears and cams in the sealed aluminum housing.

Options

• Parts Stacking - Allows a selectable number of layers for stacking parts onto a sagger or tray.

• Part Pickup Row at a Time - Pick and place a row of parts at a time this is useful if the press speed is greater than fifty strokes per minute.
• Encoder - Verifies position of stepper motors and confirms that programmed moves have been made.

• Sagger Magazine - Mounts vertically (saving floor space) at either end of the indexing conveyor. Holds loaded and/or unloaded saggers and automatically places them on the conveyor as required or stores loaded saggers.

• On-Load and Off-Load Conveyor - Designed and built as required to move loaded saggers or trays to and from loader to the next operation.

• Sagger Sand Dispenser - Will automatically dispense sagger sand on the bottom of the sagger and between layers of parts when using the parts stacking option.

• Bowl Feeders - Used to feed parts to parts conveyor.
