[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semi-automatic balance for performing mixing and weighing.

[0002]

2. Description of the Related Art Conventionally, when making a mixed packed pack of yakiniku side dishes, various kinds of side dishes are put into a pack with a fixed quantity cup, and the weight is measured when the filling is completed, and when a predetermined weight is insufficient. Was replenished with one of the prepared dishes so as to have a predetermined weight.

[0003]

However, the conventional method as described above is troublesome, and the weight of each side dish varies widely. Accordingly, it is an object of the present invention to provide a semi-automatic weigher that reduces labor by using a weighing device of a semi-automatic combination weigher and that reduces the weight variation of each prepared dish.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a weighing apparatus which excludes the combination function of a semi-automatic combination weighing apparatus having a plurality of weighing devices. A plurality of weight sensors, each of which detects a weight signal detected by each weight sensor, a control unit that receives and processes each weight signal, and outputs the weight signal.The control unit includes means for dividing each weighing tank into a plurality of groups. Means for setting a target weight value for each group, a deviation between the weight value of the object to be weighed present in each weighing tank for each group output from the control unit and the target weight value for each group, and each group. A setting / display / printing unit having means for displaying and printing the average value of the weight values of the objects to be weighed for each of the objects to be weighed. In order from each group Means for discharging each of the tanks, and means for storing and calculating the total weight of the objects to be weighed in the discharged measuring tank, and the setting / display / printing unit includes a plurality of groups for each group. Means for setting a target weight and a target total weight, and means for displaying and printing a deviation between the total weight value of the objects to be weighed in the discharged measuring tank and the target total weight and an average value of the total weight value. It is characterized by that.

[0005]

In a case where a plurality of groups of objects to be weighed are mixed and packed in a bag, an operator puts each of the objects to be weighed into each of the weighing tanks sorted into each group, and the weighing of each group is performed. The tanks are to be discharged one by one and in order to avoid stagnation, and the deviation between the weight and the target value and the average weight so far are displayed for each group, and the total weight and deviation for each time. Is also displayed. Therefore, the operator can see the weighing status at a glance and put it in by hand, so that the guide of the next feeding amount can be easily obtained, and a filled bag having a substantially uniform content can be obtained.

[0006]

1 to 5 show an embodiment of the present invention. FIG.
1A and 1B are external views of a semi-automatic combination weigher of a type in which an object to be weighed is directly introduced into the weighing tank 2, and the object to be weighed is introduced into the weighing tank 2 through a receiving port 3 from a worker's hand. In the present embodiment, since four types of objects are weighed, they are divided into four by a partition plate 4 into a group A weighing tank to a group D weighing tank. A weighing signal is issued by the attached weight sensor 5, and one weighing tank is selected from each group from among the weighing signals, and the setting / display / printing unit 12 provided in the operation control unit 10 is selected from each group. The four different weight values are displayed. Thereafter, the object to be weighed is discharged from each weighing tank 2 selected by the discharge signal, and is conveyed into the bag 7 by the conveyor 6.

FIG. 2A shows a functional block diagram for realizing the present invention. In this figure, the main body 1 of the combination weigher is
A plurality of weighing tanks 2, a gate driving device 8 for opening and closing the discharge gate thereof, a weight sensor 5 for detecting the weight of the weighing tank and transmitting a weighing signal to the control unit 10, and a weighing object discharged from the weighing tank 2 It comprises a conveyor 6 for conveying.
The control unit 11 in the operation control unit 10 includes a driving circuit 13 for operating the gate driving device 8 and the transport conveyor 6, a weight sensor 5
A to convert the weight signal from
/ D converter 15, timer 16 for CPU time control,
It comprises a PROM 17 in which the contents of the program are written, a RAM 18 as a storage device, and a CPU 14. CPU14
Performs various calculations and controls according to the contents of the program written in the PROM 17. In addition, setting / display / printing section
12 is the setting of each constant required for operation as shown in FIG.
N-OFF control, display of target weight, actual weight, deviation weight and average weight of each group and the total, printing of data, and the like are performed.

FIGS. 3 and 4 are flowcharts for realizing the present invention. In S1 of FIG. 3, the initials are set, and the grouping of the measuring tanks 2 and the target weight and other operation constants for each group are set. In S2, the object to be weighed is put into the measuring tank 2. In S3, it is determined from the weight signal whether an object to be weighed has been put into at least one of the weighing tanks of each group. In S4, one measuring tank is selected from each group. In S5, each weight value is stored and totaled, and an average value calculation is performed for each group. If there is a print command in S6, the printing of the weight or total weight is performed in S7 to S9, and if not, only the display is performed in S10. S
In FIG. 10, as shown in FIG.
Displays deviation, average value, etc. In S11, a discharge command is issued, and as a result, the object to be weighed is discharged on the transport conveyor in S12. When a series of operations is completed, the process returns to S2 to continue the operation.
The flowchart of FIG. 4 shows the details of step S4, in which a measuring tank is selected one by one from each group.
The measuring tanks are sequentially selected from 1 so that the objects to be measured do not stay. Although only the group A is shown in this flowchart, the same method is applied to the groups B, C, and D.

When four types of objects to be weighed are put into each group by the above-mentioned method, one weighing tank is selected for each group, and the objects to be weighed are placed on the transport conveyor in the order in which they are put in the weighing tanks. And put it into the upper bag 7 of the transfer. then,
Since the weight value measured for each group, and the deviation and average value with respect to the target weight are displayed, the state of the input amount can be understood at a glance, and the operator can adjust the input amount while looking at the display. It helps to make a filling bag with almost uniform contents. If necessary, the number can be printed.

[0010]

According to the present invention, according to the present invention, when a mixed bag is packed using a semi-automatic combination weigher, the individual weight, deviation, average value, etc. of each type are displayed to reduce the input amount of the worker. Since a guide is given, there is an effect that a filled bag having a substantially uniform content can be easily realized with a simple weighing machine.
