Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for weighing staple fibers, and more particularly to a method for weighing staple fibers cut from fibers of acetate, polyester, and other various synthetic fibers to a predetermined weight immediately before compressing and packing them. .

Generally, when weighing staple cotton, it is difficult to reach the specified weight in one measurement due to the small bulk specific gravity of the staple cotton, so it is weighed several times, and each measurement is carried out in exactly the same way. This is how it is done.

In other words, the staple fibers cut by the L-fiber east cutting device and transferred by the belt comparer are thrown into the weighing hopper, then the belt comparer is stopped, and the fibers are dropped and transferred from the weighing hopper to the compression packing device located below. . Conventionally, when a predetermined weight of staple cotton was weighed into the weighing hopper, the power to the belt comparer was turned off and stopped to stop the supply of staple cotton to the weighing hopper. At the same time, it does not completely stop, but instead rotates due to inertia and then stops. Therefore, when weighed and packed using such a method, the amount of each package varies, so the weight is adjusted by individually adding or removing wires from each package after packaging. Therefore, there is a drawback that the process is complicated, the work is extremely complicated, and the work cost increases. Alternatively, you may measure the time from turning off the power to the belt comparer until it stops, and turn off the power to the belt comparer and stop it earlier than this time, that is, before it reaches a predetermined weight. Even in this case, the fabric wires placed on the belt carrier are not uniform in the running direction due to their bulk, which has the drawback of causing the same troubles as described above. In view of these drawbacks, it is an object of the present invention to more accurately weigh the double-stranded wires to a predetermined weight so that the double-stranded wires do not need to be individually added or removed from each package after packaging.

Such objects of the present invention are achieved by the following method of the present invention.

That is, in the method of the present invention, when weighing the line in multiple steps, at least in the final weighing, the last weighing is occluded and the final weighing is corrected to reach the final weight. . An embodiment of the apparatus for carrying out the method of the invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention (particularly a method in which correction is made only at the last time), and FIG. FIG. 3 is a schematic cross-sectional view of the measuring device.

First, we will explain how to correct all errors in previous weighings during the final weighing using Figure 1.
When k9 is to be packaged as one package, set 300 kg in total weight value setter 1, set 50k9 in weight value setter 2, and set a value subtracted by one time, that is, 5 times, in number setter 3. The set value signal a (currently 50 kg, hereinafter referred to as "measured set value signal a") set in the measured value setter 2 is connected to the head correction circuit 5 via the gate circuit 4.The head correction circuit 5 , the measurement set value is corrected for the error caused by the free fall of the object to be weighed, that is, the soft cotton 2 rainbows from the comparer to the weighing hopper 8.The measurement set value corrected for the error due to such head difference is the measurement set value. One wheel of the hopper is given as a setting signal b, and when the weighing value in the weighing hopper 6 matches the setting signal b, a coincidence signal c is transmitted.The coincidence signal c is transmitted from the conveyor drive circuit 71 to the conveyor 2. The conveyor W2 is completely stopped, and the weighing hopper 6 of Sufu line 2Q is stopped.
When the drop to the target is completed, a measurement completion signal d is transmitted. The measurement completion signal d is applied to the gate circuit 8 to open the gate circuit 8. Therefore, the weighing value signal f is given to the storage circuit 9, which displays the weighing value each time, and the integrating circuit 10
1 is given and the total measured value from the first measurement to the current measurement is displayed. This total measured value signal g is given to the subtraction circuit Gunden, which will be described later. Since the gate circuit 4 is on the B contact side, It is not related to the set value of the hopper 6. Also, the weighing completion signal d is given to the counter blade 2 for counting, and is also given to the comper drive circuit 7 to start the comper 21 and start the weighing hopper. - Resuming feeding the suffix wire 20 to the crab.In this way, if the weighing is repeated five times with each weighing value setting being 50 kg, the count value of the counter 12 becomes 5. A match signal h is generated from the comparison circuit 13 by matching the value set in .The match signal h causes the R-S flip-flop 4
The output becomes ON. The gate circuit 15 and the gate circuit 15 are switched by the output signal of the R-S flip-flop 14. Here, the total weighing value signal g, which is the sum of the weighing values up to the fifth time, is given to the subtraction circuit Kamegawa.
00k9) (for example, 57X9 if the total measurement value signal g is 243k9) is given as the final setting signal car to the head correction circuit track, and the measurement as described above is carried out. Weighing completion signal d in the weighing of
is given as an end signal j via the gate circuit 1 and is used as a packing start signal of the packing device (not shown) or the flip-flop circuit 9, the memory circuit 9 and the integrating circuit Q.
etc. is used as a glue set signal. As above,
The process of packaging the staple wire as a 300k9 package is completed. Next, we will describe a method for setting measured values while correcting errors in the previous measurement each time the measurement is performed using the Dew Diagram.

For example, when weighing 50 kg at a time in 6 batches,
If you want to correct the second and subsequent times and pack a total of 300k9 into one package, set 50k9 to the weighing value setting device 2 and count setting device 3.
′ is set as the number of times of measurement, that is, 6 times.

Hereinafter, the setting value signal a set in the measurement setting device 2 is connected to the head correction circuit 5 through the gate circuit mother. The error caused by the free fall from the lightning to the weighing hopper 6 is corrected to the weighing set value.The corrected weighing set value is given as the weighing hopper mouse and setting signal b, and the weighing value at the weighing hopper 6 is given as the setting signal b. If this matches, “
A match signal c is transmitted. Is the match signal c a comparer drive circuit? The compare 2 re is stopped. Next, when the second comper unit comes to a complete stop and the dropping of the suffix wire 28 into the weighing hopper box is completed, a weighing completion signal d is transmitted. A metering completion signal is given to the elbow gate circuit 81 to open it. Therefore, the measured value signal f is given to the storage circuit 9.
In addition to displaying the measured value each time, the total measured value from the previous measurement to the current measurement is displayed at the top of the integrating circuit. This measured value signal f is applied to a subtraction circuit. Here, the measurement completion signal d is sent to the R-S flip-flop via the binary counter 6. Therefore, when the first measurement is completed, the gate circuit tome 8' and the b contact side are held. Therefore, the value added by 9 (i.e., 100k9) is subtracted by the adding circuit for setting signal a twice. It is given as the minuend of circuit turtle 1.The value obtained by subtracting the previous (i.e., the first) weighing value signal f from the minuend (for example, if the first weighing value signal f is 48k9, 52 kg) is the value of the second weighing. It is given to the gate circuit 4 as a correction setting signal k in the measurement of t. Also, the t measurement completion signal d is given to the R-S flip-flop wheel 4', so its output becomes ON and the gate circuit 4 is switched. , the second measurement is carried out using the correction setting signal k as the setting value.
Next, when the second measurement is completed, the gate circuit 8 is opened in the same manner as the first measurement, and the measurement value signal f is given to the storage circuit 9 to display the measurement value each time, and the integration circuit 10 and the subtraction circuit; Give me a river. Also, since the weighing completion signal d is given to the R-S flip-flop 17 via the binary counter turtle 6, when the second weighing is completed, the output is
The gate circuit 18 is switched to the N state. Therefore, the weighing value signal a (i.e., 50k9) and the previous correction setting signal k (i.e., 52kg) are given to the adder circuit 19,
The added value (ie, 102k9) becomes the minuend of the subtraction circuit 11. From this minuend, the previous time (i.e., the second
The value obtained by subtracting the measured value signal (for example, 49 kg when the second measured value signal f is 53k9) is given to the gate circuit as the correction setting signal k in the third measurement. When the third and subsequent measurements are completed, there is no change in the output status of the R-S flip-flop 1 and the R-S flip-flop member 7, so the machine operates in the same manner as when the second measurement is completed. In this way, when the measurement is repeated the number of times set by the number setting device 3' (i.e., 6 times), the count value of the counter 12 reaches 6.
When this matches the value set by the number of times setter 3', the comparator circuit 13' generates an end signal i.

This end signal i is a packing start signal or an R-S flip-flop]4' and 17, a memory circuit 9 and an integrating circuit 1.
Used as a 0 etc. glue set signal. In this manner, the process of packaging the staple wire as a 300k9 package is completed. The addition circuit 19, the subtraction circuit Fukume, the head correction circuit 5, etc. each have a memory function, and are automatically reset each time a new signal is applied. Also, the calculation commands are not explained. It is arbitrarily created based on the measurement completion signal d, etc. As explained above, according to the present invention, there is no variation in the amount of packaging between each package, and there is no need to adjust the weight by individually adding or removing cotton from each package as in the past. .
