Abstract
Provided is a free weft selector controlled by single-chip microcomputer for gripper loom, which is characterized in that: the input interface circuit connects to the primary control singlechip AT89C51 by the parallel-to-serial converter. The primary control singlechip respectively connects to the singlechip AT89C2051, output interface circuit, trip protector. The singlechip AT89C2051 connects to the electromagnet controller and the electromagnet controller connects to the electromagnet. The invention has the operation of monochrome and mixed filling, increases the weft selecting function, ensures the synchronous weaving of the textile weave and abb color, produces the two-color colored woven with the length from 2 to 8192 abb. The invention can be largely used to alternate the 1-1 mixed filling mechanism of the Sulzer PT100B330N1-1EPD1R type gripper shuttle loom to the ZQ type free weft selector.
Description
Technical field
The present invention relates to a kind of monolithic processor controlled gripper shuttle loom free weft selector.
Background technology
The monochrome that is that adopts on the Suhl longevity P71008330N1-1EPD1R matrix loom commonly used is now mixed latitude mechanism, and this device can only carry out monochrome and the operation of mixed latitude, can not select latitude arbitrarily by the requirement of look fabric kind, and look fabric kind is limited.People are carrying out the mixed latitude mechanism of the monochrome of gripper shuttle loom is transformed, but effect are all not good in order to develop more look fabric kind.
Summary of the invention
Purpose of the present invention just provides a kind of monolithic processor controlled gripper shuttle loom free weft selector, and it can carry out two look free weft selectings, guarantees that fabric tissue and weft yarn color are weaved all the time synchronously in whole process of production.
The present invention is achieved like this; it comprises input interface circuit, serializer, main control singlechip AT89C51, single chip computer AT 89C2051, electromagnet, driver, output interface circuit, power down protection circuit; input interface circuit connects serializer; serializer connects main control singlechip AT89C51; main control singlechip AT89C51 connects single chip computer AT 89C2051, driver, power cutoff protector respectively; single chip computer AT 89C2051 connects electromagnet controller, and electromagnetic controller connects electromagnet.
The present invention not only has monochromatic and mixed latitude operation, and increased the free weft selecting function, can guarantee that fabric tissue and weft yarn color weave all the time synchronously, but minimum 2 latitudes of production color cycle length, the dichromatism look fabric kind of maximum about 8192 latitudes, the cost cost is low, can be used for widely the mixed latitude mechanism changing of the 1-1 of Suhl longevity PT100B330N1-1EPD1R matrix loom is become ZQ type free weft selecting mechanism.

The specific embodiment
As shown in Figure 1; the present invention includes input interface circuit (1), serializer (2), main control singlechip AT89C51 (3), electromagnet controller (4), output interface circuit (5), power down protection circuit (6); input interface circuit connects main control singlechip AT89C51 by serializer; main control singlechip connects single chip computer AT 89C2051, output interface circuit, power down protection circuit respectively; single-chip microcomputer 89C2051 connects electromagnet controller, and electromagnet controller connects electromagnet.
As shown in Figure 2, input interface circuit has 16 end points, 16 different information of end points representative, A8, E18, E20, C8 is the loom encoder, the main axis rotation angle is a coded data, E8 finishes the detected projectile shuttle signal in back for referring to current picking, A12 is the preceding preparatory signal to whole system of loom driving, C12 refers to that a latitude restarts in the startup procedure, and A22 refers to that sensor is to loom A in service, B latitude encoder, E14, A10, A20, E12 is undefined, serializer is a serial data with every information translation of 16 end points, is input to main control singlechip AT89C51.
As shown in Figure 3, in output interface circuit, select latitude plate output signal that 5 end points are arranged, export by the ULN2803 driver, ULN2803 is a slice 8 channel transistor arrays, Transistor-Transistor Logic level is changed the CMOS level, input connects the P1 port of AT89C51, output connects exit point and light emitting diode, each end points definition: C16---externally provides red signal, E12---emergency mobile forces stop signal, E14---press the angle parking that loom is set, order when E26 changes latitude and makes mistakes, H1, H2, H3 are for selecting latitude board status demonstration light emitting diode.
As shown in Figure 4, control circuit for electromagnet comprises single chip computer AT 89C2051, magnet driver TDF1778, plug-in unit A24, C24, electromagnet, the executive component of conversion weft yarn is an electromagnet during loom operation, electromagnet inside is made of two groups of coils, center plug ground connection, in different coils, feed electric current, electromagnet armature will change traffic direction, finally trigger mechanical device and will change latitude, single chip computer AT C2051 generated frequency chopper current, P1.6 by single chip computer AT 89C2051, the P1.7 pin provides signal to magnet driver TDF1778,1 pin of TDF1778,3 pin connect plug-in unit A24 respectively, C24 whereabouts electromagnet.
As shown in Figure 5; in order to guarantee that current weft yarn promnesia does not appear in single-chip microcomputer after power down; the P3.2 mouth of single-chip microcomputer 89C51 connects the power down protection circuit; fortune claims amplifier that the thresholding of supply voltage is monitored; in case voltage falling; with causing the P3.2 mouth and extraneous interruption of AT89C51, enter the power down protection program, data keep the scene intact.
