Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a weighing device and a weighing and pricing device using the same.

(Prior art and its problems) Conventionally, weighing and pricing devices have been equipped with a device in which a weighing device, an automatic packaging device, and a labeling device are sequentially arranged on a product transportation path (Fig. 6), or an automatic packaging device on a product transportation path. There is a device (Fig. 6) in which a scale, a measuring device, and a label pasting device are arranged in sequence, and in each case, the main data regarding the product handled, such as unit price, tare weight, etc., is input through a console section with an input operation section. After finishing the data setting work of inputting the date, product name, code number, etc. into the central processing unit CPU, the product is carried into the weighing machine (in the case of Fig. 6) or the packaging machine (in the case of Fig. 6).

However, some of the above products include products that vary in weight and need to be weighed (hereinafter referred to as irregular-sized products), as well as products that have uniform weight and do not need to be weighed, such as minced meat balls (hereinafter referred to as "non-standard products"). , which are standard products).

However, in the case of irregular-sized products, regardless of whether the device shown in Figure 6 or above is used, the product is weighed on the scale, and the product transfer machine on the scale is operated when the measurement becomes stable or when the measurement is completed. It is activated to move the product from the scale to the transport path, and the weight data obtained by the scale and the price data calculated by the central processing unit CPU are sent to the label applicator along with the required data, and the label applier Label printing operation is activated.

However, in the case of fixed-pack products, the weight and/or price data is input from the input operation section during the data setting process, so there is no need to use a weighing device, and the transportation method used is the same as for non-fixed-pack products. If this happens, the weighing device will operate, causing errors in the label print data, and the product will not be moved until the weighing operation is completed or stabilized, making it impossible to speed up the work. Therefore, in the conventional device shown in FIG. 6, the product transport entrance for irregular-sized products is set to S, and the transport entrance for fixed-sized products is set to S', or a bypass transport path R is provided to bypass the weighing device. The product is conveyed through the conveyance path R when the product is a fixed quantity product, and in the apparatus shown in FIG. The goods are conveyed along the conveyance path R'.

However, in the above-mentioned conventional system, the one in which two entrances are provided not only makes the work cumbersome but also causes errors in the work, and the one in which the bypass conveyance paths R and R' are provided has the disadvantage that the apparatus becomes complicated.

(Objective of the present invention) The present invention aims to eliminate such conventional problems, and in the first invention, a fixed-length product on a measuring instrument is transferred to the next product by a product transfer machine without the measuring operation of the measuring instrument. The purpose of the second invention is to increase the speed of product conveyance by moving the product toward the working machine and setting the same product inlet for irregular-sized products and fixed-sized products, and to maintain the simplification of the device structure. In the case of a weighing and pricing device using the above-mentioned weighing device, it is possible to speed up the weighing and pricing work of fixed-size products by advancing the start timing of the label issuing operation of the label applicator along with the product transfer operation on the weighing device. purpose.

(Structure of the Invention) The weighing device of the present invention includes a determining means for determining whether a product on the scale is a non-fixed-piece product or a fixed-piece product, and a case where the determining means determines that the product is a fixed-piece product. The weighing and pricing device of the present invention is characterized in that the weighing and pricing device of the present invention is characterized in that the starting means for starting the product transfer machine regardless of whether the weighing device of the weighing device is stable or measurement is completed is provided. It is characterized in that the label issuing operation is activated together with the label issuing operation.

(Function) According to the present invention, when the discriminating means determines that the product on the weighing instrument is an irregular-sized product, the weighing device activates the transfer machine by the starting means regardless of the weighing operation of the weighing instrument. When the product is determined to be a fixed-size product by the determining means, the starting means activates the transfer device to move the product onto the scale without the scale performing a weighing operation. Move from.

Further, in the weighing and pricing device of the present invention, when the determining means determines that the product on the scale is a non-standard size product, the starting means starts the transfer machine after the scale completes a predetermined weighing operation. At the same time, the product is moved from the weighing scale, and a label issuing operation of the label applicator is activated, and when the product reaches a predetermined position, a label is affixed to the product.

If the determining means determines that the product is a fixed-size product, the starting means activates the transfer machine to move the product from the weighing scale, regardless of the weighing operation of the scale, and the product is labeled on the label applicator. A printing operation is activated, and a label is attached to the product when the product reaches a predetermined position.

(Example) To explain an example of the present invention with reference to the drawings, the first example is as follows.
Since the measuring device of the invention is also configured in the second invention, it will be described as being included in the second invention for convenience of explanation.
FIG. 1 shows a weighing and pricing device, where 1 is a product conveyance path, 2 is a weighing device, 3 is a label pasting device, and A is a console section in which a central processing unit (CPU) is housed. The product conveyance path 1 is a path for transporting the product 10 from the scale 2 toward the label pasting machine 3, and the transport means includes a conveyor 4 with a pusher on the half side of the scale 2, as shown in the figure, for label pasting. A belt conveyor 5 is used for the half of the container 3 side. Note that the conveyance path 1 is not limited to the configuration shown in the drawings; for example, it may have a configuration in which a passage 6 leading to an automatic packaging machine (not shown) is connected to the weighing device 2 side, and a product discharge path 7 is connected to the belt conveyor 5 (a second 6), or an automatic packaging machine (not shown) may be interposed between the conveyors 4 and 5 (corresponding to FIG. 6).

The weighing device 2 weighs the product 10 and outputs the weight data of the product to the central processing unit CPU of the console section A, and also outputs a weighing stability signal or a weighing completion signal P at certain times during the weighing operation.

In addition, the determination of stability or completion of the weighing operation is made using the weighing device 2.
The central processing unit may execute a predetermined program to determine whether the fluctuation of the measurement signal supplied from the to the central processing unit CPU has fallen within a certain range.

The console section A incorporates the central processing unit CPU, and has an input operation section a connected to the CPU, and a display section b, and the input operation section a has a preset key a ₁ , a number key (numeric keypad) a ₂ , and a command By operating keys such as key a ₃ , the central processing unit
Output to.

The central processing unit cpu memorizes and holds the required product data transmitted from the input operation section a, and also processes the price data based on the weight data transmitted from the weighing instrument 2, and outputs the weighing stability signal or the weighing completion signal P. When the output is received, the necessary data is sent to the display part b and the label applicator 3 along with the display signal Q ₁ and the print signal Q ₂ , respectively, the data is displayed on the display part b, and the label is issued to the label applicator 3. Start the operation. The printing signal _Q2 constitutes a starting means for starting the label issuing operation of the label applicator 3.

Further, when the weighing stability signal or the weighing completion signal P is output, the central processing unit CPU outputs the product transfer signal _Q3 and transfers the product to the pusher-equipped conveyor 4.
The drive motor is started, and thereby the product 10 on the scale 2 is moved by the conveyor 4 in the direction of the conveyor 5.

The above-mentioned product transfer signal _Q3 constitutes a means for starting the conveyor 4.

The conveyor 5 conveys the product 10 inherited from the conveyor 4 to the bottom of the label applicator 3, and when the product 10 reaches a predetermined position, the label applicator 3 sprays and attaches the issued label to the top surface of the product 10. It is something.

The timing at which the central processing unit CPU outputs the display signal Q ₁ , print signal Q ₂ , and product transfer signal Q ₃ is immediately after the weighing stability signal or weighing completion signal P is input, or at a certain time later than that. Either option is optional.

The above configuration is for carrying out weighing and pricing work when the product 10 is an irregular quantity product, and the following configuration is provided in order to apply it to a fixed quantity product.

That is, the central processing unit CPU is provided with a determining means for determining whether the product 10 is a non-fixed-pack product or a fixed-pack product, and in the embodiment, determines that the product 10 is a fixed-pack product, that is, a product that does not require weighing. A determining section 20 is connected and provided. The mode of the determining section 20 is as follows.

A determining section 20 is provided between the input operation section a and the central processing unit cpu (FIG. 2).

The determining unit 20 determines whether the product is a fixed-size product based on the type of data input to the central processing unit CPU by the input operation unit a.

For example, in the case of an irregular quantity product, unit price data is always input using the command key a ₃ and number key a ₂ of the input operation section a, but in the case of a fixed quantity product, the unit price data is not input.

Therefore, it is possible to determine that the product is a fixed-price product when there is no unit price data input in the input data.

Further, the input operation section a is provided with a changeover switch 21 for irregularly-packed products and fixed-pack products, and by turning on the switch 21 to the fixed-pack product side, the discrimination section 20 determines that the product is a fixed-pack product.

The discriminating section 20 outputs a detection signal P' to the central processing unit CPU when it discriminates from the input data or the changeover switch 21 as a fixed-piece product.

Central processing unit cpu that inputs the above detection signal P′
When it is determined that the product 10 is on the scale 2, the product transfer signal _Q3 and display signal described above are sent.
Q ₁ and print signal Q ₂ are output.

That is, when the product 10 is placed on the weighing scale 2, the central processing unit CPU that has detected the detection signal P′ outputs the signals Q ₁ , Q ₂ , and Q ₃ in priority over the weighing stability signal or the weighing completion signal P. do.

The means for determining the presence or absence of a product on the scale 2 is activated when the scale 2 weighs a predetermined low weight (for example, 20d) or more, or when the scale 2 is equipped with a product detector 22 (FIG. 1). , when the detector 22 detects that the product 10 is present, a detection signal P'' is output.

Therefore, the central processing unit cpu inputs and stores the detection signal P' when it is output from the input operation section a, and then inputs the signals Q ₁ and Q ₂ each time the detection signal P'' is input. , outputs Q ₃ .

A discriminator 20 is installed near the measuring instrument 2 (FIGS. 3 and 4).

This discrimination unit 20 is an optical sensor, for example, a light sensor or a color sensor, and detection marks 2 such as symbols or color coding on the product 10 or its packaging material to distinguish fixed-pack products from non-fixed-pack products.
3 is provided, and when the discriminator 20 detects the mark 23, the detection signal P is sent to the central processing unit cpu.
Output to .

In this discrimination mode, the presence or absence of the product can be simultaneously determined by the discrimination unit 20, so that the central processing unit cpu outputs the signals Q ₁ , Q ₂ , and Q ₃ every time only the detection signal P is input.

Note that the following method may be used as other determination means.

In other words, the weighing label printer stores the unit price, product name, etc. in advance according to the product number, and when issuing a label, it is only necessary to input the product number, but by inputting this product number, the central processing To determine whether a device is a fixed-size product or not.

Therefore, when the product 10 is loaded onto the weighing instrument 2 automatically or manually and the determining unit 20 does not detect that it is a fixed-size product (signals P′, P″ or P
The product 10 is transported by the conveyor 4 as a normal irregular-sized product after the measuring device 2 completes the predetermined measuring operation, and is labeled by the label applicator 3 while being transported on the conveyor 5. . Then, when the determining unit 20 detects that the product is a fixed-size product (signals P', P'', or P are output), the central processing unit CPU outputs signals Q ₁ , Q ₂ , and Q ₃ at that time. Therefore, due to the transfer signal Q ₃ , the fixed-piece product on the scale 2 starts to be moved from the top of the scale 2 by the conveyor 4 without going through a predetermined weighing operation, and at the same time, due to the print signal Q 2 , the product on the scale 2 starts to be moved from the top of the scale ₂ by the conveyor 4 without going through the predetermined weighing operation.
starts the label issuing operation, and the product is transferred to the conveyor 5.
A labeling operation is performed while the top is being transported.

The above working operation is shown in the flowchart of FIG.

(Effects) Since the first invention weighing device of the present invention is constructed as described above, whether the product on the weighing device is an irregular-sized product or a fixed-sized product, the same transfer device is used to transfer the product to the next working machine on the conveyance path. For example, the transfer machine can be moved toward a working machine such as a packaging machine or a label pasting machine, and in the case of fixed-pack products, the start-up timing of the transfer machine can be earlier than in the case of irregular-pack products. Since the opening is in one place and there is no need to provide a bypass passage, the work is done in one place and is not troublesome, and the equipment structure can be simplified. You can speed up your work by shortening the time required.

Further, since the weighing and pricing device is configured like the second invention weighing and pricing device, the start timing of the transfer machine in the weighing device and the start timing of label issuing by the label applicator can be brought forward, and therefore the effect of the first invention can be achieved. In addition, in the case of fixed-pack products, the time required from product delivery to pricing work can be further shortened, and work efficiency can be improved.
