Abstract
The invention discloses a two-disc sensor comprising a support, a conveyor belt and a sensing mechanism. The two-disc sensor is characterized in that the sensing mechanism is fixed on the support through a hinge upper half, a gap between the bottom edge of a hinge lower half and the conveyor belt ranges from 0.2mm to 1.1mm, the hinge lower half fits a probe, and a mechanism generating signals by engaging and disengaging is formed. The two-disc sensor has the advantages such as simple structure, low manufacture cost and high reliability and is capable of effectively recognizing two discs, without mistaken judgment caused by impurities, and normal production is ensured.
Description
Technical field
The present invention relates to the two dish induction installations of a kind of CD and two dish inducing method, especially can distinguish two dish and impurity by failure-free, guarantee that CD printing is not subject to erroneous judgement to affect production.
Background technology
In CD printing at present, two dish induction great majority adopt the induction of correlation optical fiber.Consult Fig. 4, the two dish induction installations of a kind of CD generally include support 1, fix screw 2, structure of fiber_optic 3, laser transimitter 4 and laser pickoff 5, CD transport tape 6 is positioned at structure of fiber_optic 3 middles, the normal CD 7 of normal transport is positioned at the groove of CD transport tape 6, the upper surface of normal CD 7 is parallel with the surface of transport tape 6, the center of laser transimitter 4 is higher than the surface of transport tape 6, and distance is not more than 1.2mm.
Consult Fig. 5, in the two dish induction installations of the CD shown in Fig. 4, improper CD 8 is stacked in and on normal CD 7, causes two dish, the thickness of improper CD 8 is 1.2mm, be greater than the distance between the center of laser transimitter 4 and the surface of transport tape 6, during two dish process structure of fiber_optic 3, the laser that laser transimitter 4 sends can be stopped by improper CD 8, laser pickoff 5 cannot receive laser, trigger alarm device.
Consult Fig. 6, in the two dish induction installations of the CD shown in Fig. 4, due in presswork process, often there is ink 9 to drop on transport tape 6 and normal CD 7, when at this moment ink 9 is by structure of fiber_optic 3, also can make laser pickoff 5 cannot receive laser, cause inductor erroneous judgement, thereby impact is normal, produce.
Through Chinese publication retrieval, do not find the scheme identical with present patent application.
Summary of the invention
The technical matters solving: can not well distinguish the deficiency of two dish and impurity in order to overcome two dish induction technologies of prior art, the invention provides a kind of induction two dish induction installations and a kind of two dish inducing methods that use this device more accurately.
The two dish induction installations of CD of the present invention, comprise support, transport tape, induction mechanism, it is characterized in that: its induction mechanism is fixed on support by hinge contact epimere, gap between hinge contact hypomere base and transport tape is in 0.2-1.1mm scope, hinge contact hypomere and contacts mates, form the mechanism that clutch produces signal.Gap between described hinge contact hypomere base and transport tape, preferably in 0.5-0.6.mm scope.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pair of dish induction installation, comprises support, fix screw, hinge contact epimere, hinge contact hypomere and contact.Support be positioned at transport tape directly over, hinge contact upper semisection is fixed on structure of fiber_optic, hinge contact lower semisection contacts with contact, the bottom of hinge contact is parallel to transport tape surface, and keeps certain interval, gap to be less than video disc thickness.Fix screw and contact are connected respectively the both positive and negative polarity of sensor circuit.When equipment normal operation, hinge contact lower end contacts with contact all the time, even if there are the impurity such as ink to drop on above, also cannot push contact open.When there is two video disc, because second video disc thickness is greater than the gap between contact and rotating disk, at this moment second video disc can be pushed contact open, make the up perk of hinge contact lower end, depart from contact, cause sensor circuit to open circuit, make equipment alarm, feed back to the running of PLC arrestment, reach the object of the two video discs of induction.
The present invention compared with prior art its beneficial effect is: have that structure is simple and direct, cost is low, high reliability, can effectively identify two dish, and can not judge by accident because of impurity, guarantees normal production.

In figure: support (1), fix screw (2), structure of fiber_optic (3), laser transimitter (4), laser pickoff (5), transport tape (6), normal video disc (7), improper video disc (8), ink (9), hinge contact epimere (10), hinge contact hypomere (11), contact (12).
The specific embodiment:
Below in conjunction with accompanying drawing, the invention will be further described, but embodiments of the present invention are not limited to this.
The two dish induction installations of CD of the present invention, as Figure 1-3: support (1), fix screw (2), structure of fiber_optic (3), laser transimitter (4), laser pickoff (5), transport tape (6), normal video disc (7), improper video disc (8), ink (9), hinge contact epimere (10), hinge contact hypomere (11), contact (12).Its all parts all can buy or adopt prior art manufacture to obtain; Complete machine can adopt prior art to assemble.The two dish induction installations of CD of the present invention, comprise support, transport tape, induction mechanism, it is characterized in that: its induction mechanism is fixed on support by hinge contact epimere, gap between hinge contact hypomere base and transport tape is in 0.2-1.1mm scope, hinge contact hypomere and contacts mates, form the mechanism that clutch produces signal.Gap between described hinge contact hypomere base and transport tape, preferably in 0.5-0.6.mm scope.
Refer to the two dish induction installation preferred embodiments of the present invention shown in Fig. 1 and Fig. 2, this induction installation comprises support (1), fix screw (2), hinge contact epimere (10), hinge contact hypomere (11) and contact (12).
In the present embodiment, support (1) be positioned at transport tape (6) directly over, hinge contact epimere (10) is fixed on the middle of support (1) with fix screw (2), the bottom of hinge contact hypomere (11) is parallel to transport tape (6), and keep certain gap, contact with contact (12).Hinge contact epimere (10) is connected respectively sensor circuit both positive and negative polarity with contact (12).Normal video disc (7) surface overlaps with transport tape (6) surface, can not touch two dish induction installations.
Refer to Fig. 3, when two video discs are through out-of-date, improper video disc (8) thickness 1.2mm is greater than the gap between hinge contact hypomere (11) and transport tape (6), improper video disc (8) is along with hinge contact hypomere (11) is pushed in the motion of transport tape (6) open, make up perk of hinge contact hypomere (11), hinge contact hypomere (11) is separated with contact (12), and sensor circuit opens circuit, the two dish abnormality alarms of starting, feed back to the running of PLC arrestment.And the impurity such as ink (9) are to push hinge contact hypomere (11) open, thereby well solved situation about judging by accident, occur.
