1.1.2.Electrical Control System

This tool storage systems is the main electrical control their shelves for operational control and position control. Operational control equipment, including operation of the start of braking control. Position Control is the main location and address of the shelves for testing.

1) Electric Transmission horizontal rotary tool storage systems are the mechanical movements are repeated short-term work system. And the run-time system needs some speed, speed transmission needs, the system will use VVVF method can be used simple structure, reliable operation of the motor and frequency inverter. 2) Control of the system is divided into two kinds of manual control and automatic control, manual control as a general reserve and debugging methods of work; ways to the system control computer (IPC) and the control unit (inverter contactor , etc.) consisting of a control system.

3) location and positioning accuracy of the system automatically identify the site and location using a detection device tion, timely, accurate, and comprehensive tool to reflect the inventory situation. The entire system uses a graphical interface, man-machine dialogue tips from the Chinese menu, select various functions can be realized and the importation of all kinds of information. Management system using online help function. Through the workshop management, network management and sharing of information. Have automated inventory management, warehousing management tool, a tool for the management and statistical fu as proximity switches, relays through the plate-point isolation and the number plate recorded close to the switching signal acquisition and operation of Hutchison with a Optimal Path addressable identify the current location and shelves of the purpose of the shelf location. In order to enable a more accurate positioning system, adopted two photoelectric switches, to detect the two shelves of the two films. 1.2.The functions of the knife

knife The is the role of reserves a certain number of tools, machine tool spindle in hand to achieve the fungibility a disc sc knife in the library with discoid knife, cutting tool along See how vertical arrangement (including radial

and axial from knife from knife), along See how radial array into acute or arranged in the form of the knife. Simple, compact, more applications, but are ring-cutter, low utilization of space. Figure 2.7 a) to c). D features, and the election

procedures knife more concise, and complete the space Daotao View. ATC use the knife rapid completion of STEP-7 programming, and have been tested in practice. In the positioning of the knife, PLC controlled modular design method, which future production of similar machines will be very beneficial, it is easy to use its. If the knife cutter knife is the type of library, the chain knives, and other means, in the form of the knife

and capacity according to the Machine Tool to determine the scope of the process.s, but are ring-cutter, low

utilization of space. Figure 2.7 a) to c). D features, and the election procedures knife more concise, and com

1.3.Common types

The knife is a tool storage devices, the common knife mainly in the following forms: (1) the turret knife

Including the first level turret vertical turret and the first two, see Figure 2.6 a) and b):

(2) the disc cutter

Disc knife in the library with discoid knife, cutting tool along See how vertical arrangement (including radial and axial from knife from knife), along See how radial array into acute or arranged in the form of the knife. Simple, compact, more applications, but are ring-cutter, low utilization of space. Figure 2.7 a) to c). D features, and the election procedures knife more concise, and complete the space Daotao View.
