Abstract
The present invention relates to a stock shoe detecting device and a detecting method thereof, particularly to a stock shoe detecting device and a detecting and protecting method, which is applied to a full automatic dry powder machine to prevent a mould and a stock shoe from being damaged due to mechanical failures. The detecting device comprises a rotary encoder, a programmable controller and a proximity switch. In the detecting method, under a normal condition, an upper convex mould keeps strict synchronization with the stock shoe, and the stock shoe certainly moves backwards to withdraw from a reject region before the upper convex mould moves downwards and is about to enter a concave mould. When the upper convex mould moves downwards and is about to collide with the stock shoe, the proximity switch starts detecting and ends until the upper convex mould leaves the concave mould and the stock shoe is about to recharge. The rotary encoder detects the position of the rotary angle of a spindle, and within the region, the proximity switch arranged in the withdrawal position of the stock shoe can detect the existence of the stock shoe. If the proximity switch does not detect the existence of the stock shoe, a stock shoe transmission mechanism of a press has faults, and then, the proximity switch sends out signals so that the press is controlled by the programmable controller to stop at once.
Description
Technical field
What stock shoe detector of the present invention and detection method thereof related to is to be applied on the full-automatic dry powder machine, prevents because a kind of stock shoe detector and the detection guard method thereof that mechanical fault causes mould, material boots to damage.This method is applicable to the fully automatic powder forming machine that all need the auto feed of materials boots.
Background technology
At present, the full-automatic dry powder machine all adopts the charging of material boots, owing to lack protection, in the mechanical motion, in case the material shoe system breaks down, the last punch in the motion will fiercely bump against with the material boots, cause punch and material boots to damage, and the cost that mould is scrapped be quite expensive.
Summary of the invention
Purpose of the present invention provides a kind of stock shoe detector and detection method thereof at above-mentioned weak point; be punch and the device and the guard method of expecting boots in a kind of simple, practical and reliable protection, make the device security performance of full-automatic dry powder machine (hereinafter to be referred as press) more become perfect.
Stock shoe detector and detection method thereof take following scheme to realize: stock shoe detector comprises rotary encoder (angular position sensor), Programmable Logic Controller PLC, near switch (sensor), the Programmable Logic Controller device is in electric appliance control box, Programmable Logic Controller can adopt Programmable Logic Controllers such as the Japanese KOYO SN36B1 of company type, rotary encoder is that the angular position sensor device is on the dry powder press main shaft, coaxial with main shaft, rotary encoder can adopt rotary encoders such as Japanese KOYO company's T RD-360-RZ type.Rotary encoder is by the power end V of shielded cable and Programmable Logic Controller PLC

2Link to each other.Be installed in material boots cam link side near switch, detect the motion state of cam, connecting rod, near the signal end I of switch by shielded cable and Programmable Logic Controller PLC
20, common port C links to each other, simultaneously, near switch by shielded cable and direct supply (+24V) link to each other.
The transmission of material boots derives from main shaft, and main shaft passes through 1: 1 chain drive driving cam, and the latter is converted to the circular motion of machinery by material boots connecting rod the reciprocal horizontal rectilinear motion of material boots again.The every rotation of main shaft is a period of motion of press for 360 °.In the meantime, last punch is finished powder compacting one time do vertical movement, and following closely, the material boots move horizontally and finish charging once more.Along with the rotation of main shaft, this process is constantly reciprocal.Under the normal condition, keep the synchronous of strictness between last punch and the material boots, before last punch moved downward and is about to invade die, the blanketed zone was withdrawed from the inevitable motion backward of material boots.Yet, because parts depreciation and fatigue of materials, in case chain fracture or cam are adjusted screw loosening, lose at once between last punch and the material boots synchronous, consequence described above the fact.
The detection method of stock shoe detector is: when last punch moves downward and be about to knock the material boots, begin to detect near switch, leave die material boots until last punch and be about to once more the when filling with substance end.Detect the Spindle rotation angle position by rotary encoder, pairing spindle angular position scope is 90 °～270 ° between this detection zone, in this interval, be installed in and detect the existence of material boots near switch on the material boots retracted position, do not illustrate that then press material boots gear train breaks down if detect the existence of material boots near switch, send signal near switch, stop immediately by Programmable Logic Controller PLC control press.
The characteristics of stock shoe detector and detection method thereof are simple in structure, practical; install easy to adjust; be quick on the draw; the reliability height; can be widely used on the full-automatic dry powder machine, be a kind of reliably preventing because stock shoe detector and the detection guard method thereof that mechanical fault causes mould, material boots to damage.
