Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a digital counter that automatically counts parts, such as bolts and nuts.

Recently, various digital counters (so-called counting scales) that automatically count parts such as bolts and nuts have been developed. FIG. 1 is a schematic front view of a digital counter showing one example. In the figure, a load cell as a weight sensing means and circuits for various calculations, memory, etc. are built into the casing 1, and the front panel The section includes a weight display section 2, a unit weight display section 3, and a number display section 4.
Below these, a numeric key switch 5, a tare quote button 6, a quantity setting button 7, an erase button 8, etc. are provided, and above the display section 2, a weighing start OK lamp 9 and a tare weight quota button are provided. A lamp 10 is provided.

When counting parts (of the same type) using the digital counter described above, the unit weight of the parts must be determined. Generally, the weight of the parts to be counted is very small, for example less than 2 g. However, the minimum weight scale of a counter is generally 1 g or 2 g, which makes it impossible to accurately measure the weight of a single part. Further, even if the weight of the part to be counted is, for example, 2 g or more, it is not possible to accurately measure the weight of a single part beyond the minimum weight scale of the counter.

Therefore, before counting with a digital counter, the user counts a large number of parts and sets the average weight of each part. For example, the user counts 50 parts and places them on the tray 11 of the counter. Then, the total weight of these 50 parts is measured by the counter, and "940" (g) is displayed on the weight display section 2. Next, input "50" using numeric keypad switch 5,
When the number setting button 7 is pressed, the unit weight display section 3
"1880" (mg) is displayed on the number display section 4, and "50" is displayed on the quantity display section 4. That is, through the above operations, the counter calculates the total weight (940)/number of pieces (50)=unit weight, the result is displayed on the unit weight display section 3, and is stored within the counter.

After the weight of one component has been accurately measured and set as described above, when a large number of components to be counted are placed on the tray 11, their total weight is displayed on the weight display section 2, and , this is divided by the set unit weight, and the resulting number of parts is displayed on the number display section 4.

As described above, the digital counter shown in FIG. The user must count the parts, place them on the tray 11, and set the unit weight. The more pieces you count at this time, the more accurate the unit weight will be. However, this work is very tedious, and if you make a mistake in counting, the unit weight obtained by inputting the incorrect number using the numeric keypad will be This will result in an incorrect value, and in this case, it is naturally impossible to accurately count the parts.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a digital counter that is easy to operate and can be used with peace of mind at all times. According to the present invention, this purpose is achieved in a digital counter that includes at least a weight display section, a unit weight display section, a number display section, and a placing plate, in which a predetermined number of parts are respectively placed on the placing plate. This is achieved by a digital counter characterized in that it is provided with a component constant receiver having a predetermined number of compartments formed in a square shape to receive it.

Hereinafter, details of the present invention will be explained based on illustrated embodiments.

FIG. 2 is a schematic front view of a digital counter according to an embodiment of the present invention, and parts corresponding to those in FIG. 1 are designated by the same reference numerals, and detailed explanation thereof will be omitted. FIG. 3 is a schematic plan view of the digital counter.

As shown in FIGS. 2 and 3, a component constant receptor 12 is placed on the placing plate 11 according to this embodiment. This receptor 12 has a flat rectangular parallelepiped shape as a whole, and has six horizontal partition walls 12a.
60 equal-sized chambers 13 are formed in a square shape by the 13 vertical partition walls 12b. These small rooms 1
3 is open above and below.

When counting parts, for example a large number of nuts m,
First, the unit weight of this nut m must be determined, and when this unit weight is determined, the above-mentioned component constant receptor 12 is placed on the placing plate. Next, grab an appropriate amount of nuts m and place one into each compartment 13 of the receptor 12 as shown by dotted lines in FIG. In this case, each small chamber 13 is of the same size and can only accept one nut, so the user can receive a large number of nuts m held by hand without having to insert one nut into the small chamber 13 with his or her fingers. After scattering on the body 12, if you scratch the nuts m that overflow from the small chambers 13, immediately send one nut m to every small chamber 13.
can be accepted. Since it can be seen at a glance whether nuts m have been received in all the chambers 13, a predetermined number of nuts m, in this embodiment 60, can be placed on the tray 11 very quickly.
Note that before putting the nut m into the receiver 12, the weight of the receiver 12 is tared by the tare setting button 6.

In the above manner, 60 nuts m are transferred to receptor 12.
After placing the pieces on the placing plate 11 using
is displayed, and the unit weight display section 3 shows the total weight ÷ 60.
The calculation result will be displayed. After the unit weight is set in this way, when a large number of nuts m to be counted are placed on the tray 11, the total weight divided by the unit weight is calculated almost instantaneously, and the resulting number is calculated as the number of nuts m. It is displayed on the display section 4. In addition, when counting a large amount of nuts m, the receptor 12 and the unit weight setting
Put a large amount of nuts m on top of 60 nuts m and make 60
The total number of nuts m may be counted including the 60 nuts m, or the total number may be counted by removing only the receptor 12 and adding a large number of nuts m to 60 nuts m. In the latter case, the setting of the tare weight of the receptor 12 is omitted when setting the unit weight, and the ten key switch 5 and number setting button 7 must be operated after the receptor 12 is removed. To remove only the receptor 12, simply lift it upward and only 60 nuts m remain on the tray 11.

FIG. 4 shows a modification of the component constant receptor 12, in which 25 equilateral triangular chambers 15 are formed by an equilateral triangular frame 14 and a plurality of partition walls 14b. There is. This receiver 14 also receives a certain number of nuts m, but this variant is particularly suitable for receiving spherical or disk-shaped parts. For example, as shown in A, when three parts a are received in one small chamber 15, a total of 3×
25 = 75 parts a are received, 1 as shown by B
25 parts b are received in total.

FIG. 5 shows a digital counter according to another embodiment of the invention. In this embodiment, a pair of receiving portions 16a, 1
6b, each of which has a large number of
In the illustrated example, 34 small chambers 19 are formed. In this embodiment, the frames 17a, 17b and the partition walls 18a, 18b are fixed to the tray 11 and integrated, and each small chamber 19 is open above and on one side. It is clear that a certain number of parts can also be easily accommodated with this embodiment. The parts may be removed from each chamber 19 by scraping with fingers or by using a comb-shaped removal member.

Although the embodiments of the present invention have been described above, the present invention is of course not limited to these, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, the shape of the small chamber is square or triangular in plan view, but the shape is not limited to this, and may be circular or other polygonal shapes.

In addition, in the examples shown in FIGS. 3 and 4, the receptors are placed on the placing plate 11 and parts are received therein, but these receptors are provided with bottoms, and the placing plate 11
After receiving the parts in a place different from 1, place the parts on plate 1.
It may be placed on 1.

Further, it is not necessary that all the chambers of the receiver receive the components, and for example, the group of chambers 13 in the right half or the upper half in FIG. 3 may receive the component m. In this case, the constant is 30.

As described above, the digital counter according to the present invention not only improves work efficiency compared to the conventional one, but also has the effect of allowing counting operations to be performed with peace of mind at all times.
