Abstract

The utility model discloses a polisher paper jam fault automatic detection and alarm system, capable of overcoming defects that the existing polisher is prevented from paper jam in an artificial mode, etc. The technical project of the utility model is that paper feed situation of an paper feed port of the polisher is detected real time by a singlechip technique infrared induction technique, when the paper jam fault is appeared, the power supply of the paper feed device is switched off automatically to stop feeding papers and give off an acousto-optic alarm signal; when the paper jam is taken away, the acousto-optic alarm is released and the power supply is again switched on automatically to feed papers. Thereby, the system is capable of reducing manpower cost and unnecessary loss, and improving production efficiency.

Description

The polisher paper jam error detects and warning system automatically

Technical field

The utility model belongs to the special-purpose polisher technical field of printing, and in particular, the utility model relates to the special-purpose polisher main frame of a kind of printing paper jam error and detects automatically and warning system.

Background technology

Growing along with society, people have had higher pursuit to the perfection of things, in order to satisfy needs of society, have occurred full-automatic polisher in the printing industry.Full-automatic polisher is a paper surface treatment facility of finishing technologies such as automatic paper feeding, gumming, mistake end oil, infra-red drying, the coating of UV face oil, ultra-violet curing, automatically paper collecting in the once-through operation process.The equipment compound mode that each head adopts conveyer belt to flexibly connect, but complete machine be used in combination, also separable each head uses, and can increase the greater functionality assembly, becomes on the market indispensable printing equipment in the every profession and trade.Compare with manual feed before, improved production efficiency greatly, also saved the great amount of manpower resource.

May 28 2003 day for announcing, the Chinese patent of notification number CN2552699Y discloses a kind of paper feeder of automatic polisher, include support and paper feeding slide plate, it is characterized in that support is provided with blows paper cam, paper feeding cam and lifts the paper cam, and blow paper cam, paper feeding cam and lift the paper cam and be installed in the same rotating shaft, by linear roller bearing the roller groove is installed on the described paper feeding slide plate, three cams work the big suction nozzle on the support, little suction nozzle and tuyere by mechanical transmissioning piece separately simultaneously.It is little that the paper feeder of this automatic polisher has solved in the printing industry automatic paper feeding head paper feeding specification scope of application, complex structure, and volume is big, slow-footed shortcoming, reaching paper feeding accurately, at a high speed and purpose applied widely, its compact conformation, simple, action sensitivity is reliable.Though the High-Speed Automatic paper feeding of this patent energy, the paperboard problem can appear in automatic paper feeding, and speed is fast more, and the loss that causes is big more, and main at present employing manual type prevents paperboard, workman of the special outfit of per two production lines.

The utility model content

The utility model mainly solves existing automatic paper feeding polisher paperboard can occur when automatic paper feeding, need the special workman of outfit to prevent paperboard, and inefficiency loses big technical problem; A kind of paperboard that whether can detect automatically is provided, and can reports to the police, increase work efficiency, the polisher paper jam error that reduces loss detects and warning system automatically.

For achieving the above object, the utility model adopts following technical scheme: a kind of polisher paper jam error detects and warning system automatically, comprise automatic document feeder, also comprise sensor, microcomputer, Executive Module and human and machine interface unit, described sensor links to each other with the external interrupt mouth line of microcomputer, and the I/O mouth line of microcomputer connects Executive Module and human and machine interface unit respectively.

As preferably, described sensor adopts reflective infrared photoelectric sensor, is installed in polisher paper feed port end perpendicular to paper.Described reflective infrared photoelectric sensor is installed perpendicular to paper, can better receive the infrared light that reflects; Reflective infrared photoelectric sensor is installed in polisher paper feed port end, in case paper jam error occurs, sensor can be sensed immediately, and control is in time made by system, cuts off the power supply of automatic document feeder, reduces unnecessary loss, enhances productivity.

As preferably, described microcomputer adopts the AT89S52 singlechip chip, and described Executive Module is a relay.Reflective infrared photoelectric sensor will be sensed signal and send to the AT89S52 single-chip microcomputer, the AT89S52 single-chip microcomputer judges whether paperboard according to the signal that receives, if paperboard, then single-chip microcomputer sends control signal to relay, relay cuts off the power supply of automatic document feeder, light the LED alarm lamp, single-chip microcomputer is also controlled buzzer and is sent chimes of doom simultaneously, makes sound and light alarm.

As preferably, described human and machine interface unit comprises: keyboard, charactron, LED alarm lamp and buzzer.The effect of keyboard in system is that be set the blanking time of reporting to the police, and precision is 0.1 second, and charactron then shows the warning blanking time of setting, and LED alarm lamp and buzzer are used for carrying out sound and light alarm.

The beneficial effects of the utility model: utilize SCM system that the card machine fault of polisher is detected and sound and light alarm automatically, in time cut off the power supply of automatic document feeder, reduce unnecessary loss, enhance productivity; Need not the special workman of outfit of per two production lines, reduce human cost.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.

Embodiment: the polisher paper jam error of present embodiment detects and warning system automatically, comprises sensor 1, microcomputer 2, Executive Module 3, human and machine interface unit 4 and power module, and the annexation between its each several part as shown in Figure 1.

As shown in Figure 3, microcomputer 2 adopts the AT89S52 singlechip chip, and AT89S52 is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontrollers, has 8K on-line system Flash memory able to programme, 256 byte RAM, 32 I/O mouth lines, WatchDog Timer, 2 data pointers, three 16 bit timing device/counters, 2 grades of interrupt structures of one 6 vector, crystal oscillator and clock circuit in the full duplex serial port, sheet.

As shown in Figure 4, sensor 1 adopts reflective infrared photoelectric sensor, its infrared transmitter links to each other with 14 pin of single chip computer AT 89S52 with resistance R 24 by triode Q7, sends to 12 pin of single chip computer AT 89S52 after the signal that reflective infrared photoelectric sensor is sensed is put in order through comparator U2B; Reflective infrared photoelectric sensor need be installed near the paper feed port of polisher main frame perpendicular to paper.

As shown in Figure 5, Executive Module 3 is made up of relay, and the Single-chip Controlling signal comes the adhesive of control relay and lighting of LED alarm lamp by two triode Q4, Q5, the switch of relay control automatic document feeder power supply.
