Abstract

The utility model relates to a cracked ends zone display device for a loom, which comprises an alarm loop which is arranged in a cracked ends automatic stop device of the loom. Elements for picking up signals are connected in series in the alarm loop of the automatic stop device, and both ends of the element is connected with an input loop of a trigger circuit; the output end of the trigger circuit is connected with a luminous element, and the position of the luminous element is marked with a serial number to find out the cracked ends very quickly.

Description

Loom cracked ends partition display

The utility model relates generally to the device that loom is handled cracked ends, particularly a kind of relevant therewith display.

Loom is a kind of machine that silk thread is woven into according to certain rules cloth; people claim that usually the silk thread along the cloth direction is a warp; silk thread with cloth width unanimity is a parallel, and warp and parallel are easy to fracture in producing interleaving process, and this just must shut down and handle.In loom; for example the arrow shaft loom all is equipped with Warp stop motions; described automatic stop arrangement is included in and all is installed with a menopause tablet on the every warp; elongated hole on the menopause tablet passes the iron bar of installing on the warp stop frame; have one group of inductive disks along warp stop frame; with lead with inductive disks; warp stop frame links to each other; form an automatic stop arrangement alarm circuit; menopause tablet is owing to deadweight descends when warp break; conducting warp stop frame and inductive disks, thus cause the distribution box shutdown of loom to treat to start shooting again after the operative employee ties warp.Connect cracked ends and brought difficulty,, can not directly find the cracked ends zone effectively after making spinner's warp stop motion, thereby incur loss through delay the cracked ends processing time, be unfavorable for increasing work efficiency because many warps are combined into certain width to the operative employee.

The purpose of this utility model is in order to overcome the deficiency of known technology, a kind of loom cracked ends partition display that can point out grade turner warp break position intuitively to be provided.

For achieving the above object, scheme of the present utility model is: the element of serial connection one pickoff signals in the alarm circuit of automatic stop arrangement, the two ends of described element connect in the input circuit of circuits for triggering, and the output of circuits for triggering is connected to light-emitting component, indicate the position of light-emitting component with sequence number.

Adopt such scheme, when cracked ends took place, the alarm circuit of automatic stop arrangement closed platform, there is electric current to flow through the element of pickoff signals, makes trigger upset, light-emitting component conducting so send signal, this element has the sequence number layout, so the spinner finds the cracked ends position easily.

Below in conjunction with diagram and embodiment scheme is described in more detail.

Fig. 1 is the schematic diagram of loom cracked ends partition display;

Fig. 2 is the flip-flop circuit figure of loom cracked ends partition display;

Fig. 3 is the monostable flipflop circuit diagram of loom cracked ends partition display;

Fig. 4 is the circuit diagram of loom cracked ends partition display.

As shown in Figure 1, the Warp stop motions of a warp of expression, the application's scheme must be by the mounted Warp stop motions of original equipment, this device comprises a menopause tablet (1), have a slotted eye (2) and aperture (3) on the menopause tablet (1), slotted eye (2) is through on the iron bar set on the stand (4), and aperture (3) is installed with warp.Stand is installed on the support, along the direction of warp, is provided with one group of inductive disks (5) below menopause tablet, inductive disks (5) is made with metal skin, the several regions that is divided into mutually insulated, contiguous mutually warp may belong to the same area, and these regional available digital are numbered or are met sign with other.Present embodiment be divided into four zones through line width, affiliated inductive disks marks with I, II, III, IV respectively.Inductive disks (5) connects with lead, and link to each other with the cracked ends alarm, another import pathway of cracked ends alarm is an iron bar (4) set on the stand, by the lead that connected on the iron bar (4) as input, this programme is the element that serial connection is gone into a pickoff signals in this input circuit, the resistance of present embodiment serial connection is respectively (6), (7), (8), (9), and this resistance provides signal to the input of circuits for triggering again, and these circuits for triggering are made variation according to signal.

Circuits for triggering as shown in Figure 2 are one of scheme, the circuit arrangement that can finish this function certainly a lot of but its conceive substantially all within the application's scheme.This programme is actual to be a phase inverter, form by a transistor (10) and interlock circuit, input is connected to the resistance (6) of pickoff signals, and resistance (11) provides the current potential of base stage, and resistance (12) is regulated input current, electric capacity (23) and (22) are every straight usefulness, output is connected to lamp (13), as the light indication, is serially connected with a resistance in output loop, the bulb step-down is used, prolonged the service life of bulb.When having electric current to flow through on the resistance (6), two ends produce the pulse of an electronegative position, transistor (10) conducting, and bulb (13) is bright, because bulb has numbering, represents that promptly certain zone has cracked ends to exist.

But above-mentioned circuit can make the bright time of bulb very of short duration, and for more practical, adopting a kind ofly has the monostable flipflop of long period delay function better.As shown in Figure 3.Circuit is formed typical monostable flipflop by two triodes (14) and (15) and one group of resistance capacitance element, wherein the product 0.7R of resistance (16) and electric capacity (17) ₁₆C ₁₇The time of decision time-delay, bulb (18) is serially connected with a resistance (19), and triggering signal inserts from the base stage of triode (15).

The control principle of foregoing circuit is, when circuit during in stable state, triode (15) conducting, if there is not trigger impulse, then triode (15) keeps conducting always.When negative triggering pulse arrives, that is to say when cracked ends exists, the circuit upset, triode (15) ends, triode (14) conducting, the electric current that bulb this moment (18) flows through owing to triode (14) conducting increases, and bulb (18) is bright.Because triode (14) conducting, B point current potential drops near zero volt from+EC, owing to capacitor voltage at both ends can not be suddenlyd change, A point current potential just from original zero point several volts fall to approaching-E _C, diode (20) instead ends partially, along with C ₁₇Pass through R ₁₆, diode (21), the discharge of triode (14) and power supply, discharge length is by the time decision of time-delay, and A point current potential rises gradually; When arriving 0.5 volt of left and right sides, triode (15) conducting, triode (14) ends, monostable device is returned to original state, because triode (14) wants conducting a period of time just to recover stable state, so bulb (18) wants bright a period of time just to extinguish, so enough remind the operative employee to note.

Shown in Figure 4 with above-mentioned circuit, synthetic one group of circuit bank particularly shown in Figure 2, the resistance of pickoff signals is taken from the resistance that is connected in series on the Warp stop motions of zones of different respectively in each circuit, when cracked ends exists, and the zone at the bright expression cracked ends of bulb place.

Adopt such scheme, can find out cracked ends soon, greatly improved productivity ratio.

In sum, this programme is successful.
