Industrial production is often in large quantities. In the production process, the workpiece should be sent to the working position at a certain cycle and orientation, and then removed after processing, assembly or packaging. In order to improve productivity and ensure processing quality, many processes need to be completed by automatic loading and unloading devices.
Although the structure and principle of these mechanical devices are different, they have much in common, using a common device, and the feeder is one of them.
The task of the feeder is to separate the articles or workpieces to be processed from the stocker (tank), install the processing requirements of the automatic machine, and send them to the processing position quantitatively, regularly and directionally. The feeder is mainly composed of four major components.
1. Orientation device: The orientation device ensures that the orientation of the workpiece installation process is required to be sent. Directional feeding is a key issue in single piece machining. The orientation mechanism generally works in conjunction with correction and rejection mechanisms.
2. Dosing device: The dosing device sends a specified number of workpieces in each working cycle according to the requirements of the automatic machining process. Quantitative can be divided into quantity and number. For example, alcohol, washing powder and other materials are mainly quantitative. Screws, soaps, cigarettes, etc. are mainly fixed. The volume of plastic bags, thin iron sheets, thin steel rods and other materials are fixed length. The design should be determined according to the shape, nature, and state of the material to be delivered. Dosing devices often require isolation devices, technical mechanisms, etc. to match.
3. Timing device: The timing device mainly installs the production cycle of automatic production equipment, so that the feeding mechanism works regularly and on time. In the design of the timing device, the problem of coordination between the workpiece feeding and the automatic machining rhythm is mainly solved. This is generally ensured by the kinematic drive chain between the feed mechanism and the associated other mechanism, so the motion cycle of the feed mechanism must be coordinated with the automaton work cycle. It is also possible to use a vertical drive feeding mechanism, such as a camshaft, an electromagnetic vibrating feeder, and a feeding robot, but the feeding mechanism is stopped or fed by a control system or an isolation device such as a gate.
4. Other devices: Other devices include positioning device, isolation device, straightening mechanism for winding materials, correcting and adjusting device for strip material, rejecting mechanism for missing workpieces, missing material detecting mechanism, counting mechanism, etc.
Positioning in the design of the automatic machine is also a relatively important problem. The feeding is not in place or there are deviations that affect the normal operation of the automatic machine. In the design, the positioning device can be assigned to the process actuator or to the feeding mechanism.
