Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for filling natto into a natto container and a measuring mechanism in a natto filling device, in which the filling and measuring of the natto into a container is carried out by weight.

(Prior art) Conventionally, natto is packed in a natto container by steaming soybeans at 120°C and then putting them at 70°C or higher to prevent the adhesion of germs.
It is set as 0g, 50g, and 30g, but in reality, you can just measure it by volume, and when you add sticky steamed soybeans, it will be easier to measure. When filling is done by volumetric measurement, which is not yet known as a weighing technique, that is, the conventional method of filling natto, when converted to flit, it is ±
It is unavoidable that an error of about 5% will occur, and the error increases as small-quantity products such as 50g and 30g are in high demand these days. At the manufacturing site of natto products, if the weight is low, the container is manually broken as a defective product and the soybeans, currants, and sauce inside are discarded, resulting in a loss of work and extremely low economic efficiency. Become. In addition, if there is a large number of [1], the product can be used as is, but it is still less economical than if it were measured accurately.

A typical conventional measuring mechanism in a natto filling device is shown in FIG. 4 and will be explained. The inoculated and steamed soybeans are supplied to the weighing tank B by the fixed-rate feeder A. The measuring tank has an upper shutter plate C, which is made up of a pair of left and right plates C1 and C2 and opens and closes from side to side, and a pair of left and right plates D1, which are provided below the upper shutter plate C. There is a lower shunter board made of D2 that opens and closes to the left and right. A storage room E is formed by the lower shutter board and the upper shutter board C.
is formed. With this configuration, the upper shutter C is initially opened and the lower shutter D is closed, and the inoculated and steamed soybeans that are continuously supplied from the constant supply feeder A to the measuring tank B are placed on the lower shutter D. It accumulates, fills the storage chamber, and then reaches above the upper shutter C. At this point, the upper shutter C closes, and then the lower shutter D opens, so that a predetermined volume of inoculated and steamed soybeans is dropped into the natto container F below. Then, when the lower shutter D is closed again and the upper shutter C is opened, the storage chamber E is filled with inoculated and steamed soybeans, and by repeating the same operation, the lower natto containers F are filled with a predetermined capacity. Natto will be added.

(Problems to be Solved by the Invention) In the conventional measuring mechanism described above, not only does the above-mentioned disadvantage associated with volumetric measurement naturally exist, but also the upper and lower shutter plates C, D
Since the opening and closing of the shutter will be done about once every few seconds, the steamed soybeans will be crushed by the opening and closing operation, and the shutter plates C and D will become dirty. There was the hassle of having to clean it.

The present invention eliminates the measurement error associated with volumetric measurement by performing the method of adding natto by weight measurement, and
Fi! We aim to improve economic efficiency by eliminating the occurrence of defective products due to shortages, and also eliminate the need for a shutter plate in the weighing mechanism, eliminating the crushing of steamed soybeans during measurement and avoiding the work loss associated with conventional shutter plate cleaning. It is an object of the present invention to provide a new weight measuring mechanism that can achieve accurate weight measurement.

(Means for Solving the Problems) In order to achieve the above object, the present invention employs weight measurement as a means for adding natto, and has a weighing tank whose bottom can be opened and closed, and the inoculated steamed soybeans are weighed in the weighing tank. A fixed-rate feeder that supplies the tank, and a system that controls the supply amount of the fixed-rate feeder, detects the weight of the inoculated and steamed soybeans put into the measuring tank, and weighs the inoculated and steamed soybeans when a predetermined weight of the inoculated and steamed soybeans is put into the measuring tank. It is equipped with a load cell that outputs a signal to open the bottom of the tank.

In addition, a hopper with a bottom that can be opened and closed is installed below the measuring tank, and the inoculated and steamed soybeans dropped from the measuring tank are put into the hopper, and then the bottom of the hopper is opened and the soybeans are poured into the natto container. It is also possible to allow the inoculated and steamed soybeans to fall and be stored.

Furthermore, if multiple weighing tanks are installed for one hopper, accurate measurement from the supply feeder to the weighing tank can be achieved. When feeding in quantity, the feeding speed becomes slightly slower, and even if there is a time lag between the feeding speed of the natto container and the feeding speed of the natto container, this can be adjusted using the hopper, which is an advantage.

(Function) The metering mechanism in the natto filling device configured as described above adjusts the supply amount of the quantitative supply feeder to large input, small input, and stop supply as necessary based on commands from the load cell. A predetermined weight of inoculated and steamed soybeans is accurately put into the measuring tank. When a predetermined weight has been input, the bottom of the measuring tank is opened in response to a command from the load cell, and the inoculated steamed soybeans are allowed to fall into the natto container.

If a hopper is provided below the measuring tank, the inoculated and steamed soybeans are temporarily dropped into the hopper and stored, and when the bottom of the hopper opens, the inoculated and steamed soybeans finally fall into the natto container. I am forced to store it.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3 of the accompanying drawings.

In the figure, 2 is a total of 1 in the natto filling device according to the present invention.
It is a tia structure. The weighing machine JR2 has a quantitative supply feeder 6 installed on a base 4. The fixed quantity feeder 6 includes a fixed quantity feeder main body 6a installed on the base 4 with a spring means 8.8 interposed therebetween, and a fixed quantity feeder main body 6a installed on the upper part of the fixed quantity feeder main body 6a, and configured to feed inoculated and steamed soybeans by induction. It has a supply gutter 10. Inoculated and steamed soybeans refer to soybeans that have been steamed in a conventional manner and inoculated with Bacillus natto in a conventional manner. The fixed quantity supply feeder 6 is entirely vibrated to move and supply the seedlings and steamed soybeans placed on the supply gutter 10 in the direction of the tip while vibrating them.

Reference numeral 12 denotes a support plate erected at the tip of the base 4, and an upper substrate 14 is provided on the support plate 12 so as to extend laterally. A measuring tank 16 is attached to the tip of the upper substrate 14, and the measuring tank 16 is located below the narrow supply port 10a at the tip of the supply gutter 10, and the inoculation is supplied by dropping from the supply port 10a. The top is open so that steamed soybeans can be stored and weighed. Reference numeral 18.18 denotes a pair of opening/closing plates constituting the bottom of the measuring tank 16, which are rotatably attached to the shaft 20.20 and can be opened and closed by air pressure from the air cylinder 22.

24 is a lower substrate provided below the upper substrate 14 via an auxiliary plate 26 provided at the tip of the base 4.

A hopper 28 is provided at the tip of the lower substrate 24, and the hopper 28 is located below the measuring tank 16, and is configured to store the inoculated and steamed soybeans that are dropped and supplied from the bottom opening of the needle measuring tank 16. It has become. 30 is a shutter plate constituting the bottom of the hopper 28. The shutter plate 30
By moving the hopper 28 sideways, the bottom of the hopper 28 is opened, and by moving it back, the bottom is closed. The shutter plate 30 is operated by a pneumatic mechanism (not shown), and when inoculated and steamed soybeans are present in the omper 28 and the natto container F is below, the shutter plate 30 is pulled sideways and closes to the bottom. opens,
The inoculated and steamed soybeans are dropped and stored in the natto container F.

32 is a load cell installed on the upper surface of the support plate 12. The load cell 32 has a built-in computer, detects and displays the weight of the inoculated and steamed soybeans supplied to the weighing tank 16, and also displays the weight of the inoculated and steamed soybeans supplied to the measuring tank 16.
When a predetermined weight of inoculated and steamed soybeans is put into the needle metering tank 16, a signal is issued to open the bottom of the metering tank 16, and the air cylinder 22 is actuated to close the opening/closing plate 1.
However, if there is the hopper 28 described above, the opening/closing plate 18.18 is opened only when it is confirmed that there are no inoculated and steamed soybeans in the hopper 28. Of course, it is controlled to open.

According to the command from the load cell 32, the quantitative supply feeder 6 drops and supplies the inoculated and steamed soybeans to the measuring tank 16 while controlling the supply amount, but the mode of supply is usually large input or small input. For example, if 100g is to be input, the inoculated and steamed soybeans are quickly supplied to the measuring tank 16 with a large input at first, and when it reaches 95g, it is gradually input as a small input, and when it reaches 100g, the supply is stopped. If controlled in such a way, accurate weight measurement can be performed. Furthermore, it is also possible to perform accurate weight measurement by continuously adding small amounts without providing a supply stop state and by correcting the head difference.

According to the configuration described above, initially, a specified 1 tBit of natto, for example, 100 g, is set using the load cell 32, and the inoculated and steamed soybeans are introduced into the weighing tank 16 from the quantitative supply feeder 6 by a large amount, until the amount approaches the specified weight [1 , for example 9
When the amount reaches 5g, the feeding mode is switched to small injection according to the instruction from the load cell 32, and the amount is gradually added to exactly 100g.
When that happens, input is stopped. Immediately, the opening/closing plate 18°18 opens according to the instruction from the load cell 32.
The 100 g of inoculated and steamed soybeans inside falls downward and is stored in the hopper 28. Then, the shutter plate 30 of the hopper 28 is pulled laterally to open the bottom, and the inoculated and steamed soybeans further fall and are stored in the natto container F. On the other hand, the opening/closing plate 18 closes as soon as the measuring tank 16 becomes empty, and the metering feeder 6 again starts supplying the inoculated and steamed soybeans to the measuring tank 16 in a large loading state. Similarly, when the value is close to the set mWk, it switches to small loading, and when the set weight is exactly reached, loading is stopped. Thereafter, the above-described operations are repeated to store inoculated steamed soybeans one after another in the natto containers.

In the above embodiment, as a preferable example, the hopper 28 is installed below the measuring tank 16, but this hopper 28 is not necessarily necessary, and the inoculated and steamed soybeans are directly dropped from the measuring tank 16 into the natto container F. It can also be stored.

In addition, in the above embodiment, the homper is
Although we have shown an example in which two or more weighing tanks are installed in correspondence with each other, if multiple weighing tanks are installed for one hopper, the feeding speed will increase when accurately feeding weight from the supply feeder to the weighing tank. This has the advantage that even if there is a time delay between the feeding speed of the natto container and the feeding speed of the natto container, the hopper can correct the situation.

In addition, in the above explanation, the supply gutter 1 of the quantitative supply feeder 6
0 is supplied with inoculated steamed soybeans, and the inoculated steamed soybeans are weighed in the weighing tank 16. It is also possible to adopt a process in which the mW is measured, the natto is stored in the natto container F, and then the bacteria are inoculated.

(Effects of the Invention) According to the present invention, by performing the method of filling natto by weight measurement, it is possible to eliminate measurement errors associated with volumetric measurement and eliminate the occurrence of defective products due to insufficient weight, thereby improving economic efficiency. Furthermore, the weighing mechanism eliminates the need for a shutter plate, which eliminates the crushing of steamed soybeans during weighing, avoids the work loss associated with conventional shutter plate cleaning, and achieves accurate fift weighing. can be played.
