Along with this accommodation operation, each storage operation circuit 27-1 to 27
-n switches 32-1 to 32-n are turned on, so the memorability stored in the direct memory devices 31-1 to 31-n is as follows.
The weights of the objects to be weighed 11i stored in the left side memory hopper are stored in the weight storage units 28-1 to 28-n, respectively.

The next objects to be weighed from the intermediate hoppers 14-1 to 14-n are stored in the empty 81st hoppers 16-1 to 1G-〇, and the next objects to be weighed from each ff1l17-+ to 17-n are stored. The funeral hieroglyphs are output to adders 30-1 to 30-n and 40-+ to 40-n.

The ejection games h 1 9-1 to 21-n on the side) are spaced apart, and the right-side memory hoppers 21-1 to 21-nt are accommodated therein.

At this time, since the switches 42-1 to 42-n of each memory calculation circuit 27-1 to 27-n are turned on, the memory values stored in the addition 1st shift 3rd shift 41-1 to 41-0 are The weight values of the objects to be weighed accommodated in the memory hoppers 21-1 to 21-n are stored in the weight storage devices 38-1 to 38-o, respectively.

Also, during this period, the objects S1 supplied from the feeders 13-1 to 13-n to the intermediate hoppers 14-1 to 14-n are stored in the empty 31 m hoppers 16-+ to 16-1. Then, each metric is sent to the adder 30-1.

The stored values of each weight memory device 28-1 to 28-n, 38-1 to 38-0 are sent to and output from the matching selection circuit 5o together with each weighing field from the weighing devices 17-1 to 17-n, When the combination request signal B is input, the combination of weights closest to the set weight of the object to be weighed within a predetermined range is selected.

In this matching selection, for example, if the object to be weighed housed in the weighing hopper 16-1 and the cutting speed housed in the memory hopper 20-1 are selected as a match, then these hoppers A combination selection signal corresponding to the above is sent to the discharge supply control I device 49.

The discharge supply control device 49 receives this dark blue matching selection signal and selects the discharge goo 1 to 18-, 22- of the selected hopper.
Open 1.

As a result, as shown in Figure 3, five were selected by the association.
The object to be weighed in the first output hopper 16-1 falls into one collection chute together with the object to be weighed in the memory hopper 20-1, which has been selected for the same combination, and then falls into one collection chute together with the object to be weighed from the memory hopper 20-1, which has been selected in the same combination.
It is collected in a timing hopper 25 together with the it-lit items and packaged by a packaging machine 26.

At this time, the two switches-1 of the memory calculation circuit 27-1 are set to ONL, and the first memory of the weight memory 28-1 is reset to "O".

In this extraction operation, the object to be weighed is stored in the empty hopper from the intermediate hopper, and the object to be weighed is stored in the empty memory hopper. The accidental value of the object to be tI is stored in the memory unit corresponding to the memory hopper accommodated in the above-mentioned unit, and the next combination selection operation is performed.

In the same way, send a combination request '? Each time iB is input, the combined discharge operation of the objects to be weighed is repeated.

Here, for example, if the supply fleas of the occupied tffi items supplied from the feeders 13-+ to 16-1 fluctuate rapidly and become smaller, the combination selection circuit 50 determines that the occupied fft l items are supplied within a predetermined range. When the combination 1 that is closest to the predetermined weight 1 cannot be obtained, the combination selection circuit 'NJ49 outputs the combination no 01 fg of the 'H° level' to the AND circuit 53.

At this time, all weighing hoppers 16-1 to 16-0 and memory hoppers 20-+ to 20-n, 21-+ to 21-n
When the object to be weighed is accommodated in the hopper, the output of the detection circuit 51 becomes the "tobi" level, the output of the AND circuit 53 becomes the "tobi" level, and the OR circuit 56 inputs the additional input signal A to the additional immersion hopper selection circuit. be done.

At this time, each memory calculation circuit 27-1 to 27-n stores the weighing value of the weighing hopper in which the object to be weighed is stored, and the weight of the object to be weighed stored in the left and right memory hoppers corresponding to each 1 m hopper. The first side entrance to the other hanging field is the smell shore fir.
To the i setting device/I7! When compared with the first shift, only the added value smaller than the reference value is input to the additional input hopper selection circuit 48.

Therefore, in the additional input hopper selection circuit 48, when the additional input signal Δ is input, the minimum addition i[ is detected among the input addition values, and the memory hopper corresponding to this minimum addition value is selected. Selection [No. 3 is discharge supply 1 crime device 4
sent to.

Here, for example, if the addition value of the addition field memory 31-1 is selected as the minimum addition (direct), this selection is performed by the four discharge supply control Il devices that have received a selection signal from the additional input hopper selection circuit 48. The discharge gate 18-1 of the weighing hopper 16-1 corresponding to the memory hopper 20-1 is opened,
The object C1 A in the cutting 1n hopper 1G-1 is in the memory hopper 2.
Added to the score at 0-1.

At this time, the switch 32-1 is turned on, and the minimum

As a result, the combination selection circuit 50 selects combination 1.
When 1I production is started and 11 combinations are made through this combination selection operation, the weighing hopper and memory hopper J selected together in the same manner as above, and the weighing material are discharged, and the collection chute 24 and timing hopper 25 are discharged. It is then discharged to the packaging machine 26.

Further, if the combination selected by the combination selection circuit 50 cannot be selected, the additional input signal A is sent to the additional input hopper selection circuit 48.
Then, in the same way as above, the objects to be weighed are additionally loaded into the selected memory hopper, and the value of the object to be weighed newly stored in the empty weighing hopper is combined and selected. The signal is sent to the circuit 50 and a combination selection operation is performed.

Also, as the production is about to end, the circular feeder 12/1
If the objects to be weighed on the day of 13-1 are not fed to each feeder 13-1 to 13-n uniformly but rather in a pot, the objects to be weighed will be stored only in a specific memory hopper group. Become.

In such a state, if the optimal combination of the objects to be weighed by the combination selection #J is not 1q three times in a row of the limit value, the comparator 58 adds Ω (through the OR circuit 56) (input signal △
is sent to the additional input hopper selection circuit 48, and after receiving the additional 1 in the same manner as described above, the combination selection V] is performed again.

As described above, additional IQ input is performed until a combination weight close to the set Ichikawa is obtained within a predetermined range, and the combination is discharged!
The process continues.

Other Embodiments of the Present Invention J3 In the above embodiment, the operator was stationed at the 11th shift of the object to be weighed to select the combination and select the additional immersion hopper. Instead, the above selection can be made based on the number of pieces obtained from the weight value, or based on the number of pieces where weight is 100.

In addition, in the above example, the sum of the weight of the object to be weighed stored in the weighing hopper and the weight of the weight of the object to be weighed stored in the memory hopper are compared, and the minimum added value is determined. The wave meter (m) was added to the corresponding memory hopper, but this is not limited to the minimum addition value (for example, even the maximum addition value).

An intermediate addition of ty+tu may be used, or objects to be weighed may be added to a plurality of memory hoppers at the same time.

Further, in the above embodiment, the reference value of the reference value setter 47 is set to the set weight of the object to be weighed, but it may be set to a value lower than the set weight value. It may be possible to set the il output limit to 1 shift.

Note that the present invention is not limited to the circuit groove configuration of the above-mentioned example, and various modifications and applications are possible without departing from the gist of the present invention.

・Effects of the present invention> As is clear from the above explanation, the combination V meter lifting device of the present invention combines the objects to be pulled housed in the weighing hopper and the memory hopper, resulting in the optimal combination for the set amount. is 1
4, if the object to be weighed that has been trained and stored in the weighing hopper is added to one of the corresponding memory hoppers, the new object to be weighed is stored in the δLffi hopper and weighed, and then the combination is The optimal combination for the set amount is set to one value.

Therefore, the weighing operation does not stop due to not being able to find the optimal combination of objects to be weighed, and the weighing operation does not stop as usual.
+ No need for tedious work for re-cropping.
