Description

The present invention relates to a counter.

[Prior art]

Recently, various digital counters (so-called counting scales) for automatically counting parts such as bolts and nuts have been developed. FIG. 1 is a schematic front view of a digital counter showing an example thereof, in which a casing is shown.
A load cell as a weight detection means and a circuit for performing various calculations and storages are built in (1), and a weight display section (2), a unit weight display section (3) and a number display are provided on the front panel section. A part (4) is provided, and a numeric keypad switch (5), a number setting button (6), a delete button (7), etc. are provided below these, and a mounting tray (8) is provided at the top. There is.

When counting the parts (of the same kind) with the above digital counter, the unit weight of the parts must be obtained. Generally, the weight of the parts to be counted is very small, eg 2
g or less. However, the minimum scale for weighing the counter is generally 1 g or 2 g, which cannot accurately weigh one component. Further, even if the weight of the component to be counted is, for example, 2 g or more, it is impossible to accurately weigh one component above the minimum weight scale of the counter.

Therefore, before counting by the digital counter, the user counts several parts to set the average weight of one. For example, a user may count 50 parts and place a counter pan (8)
Put on. Then, the total weight of these 50 parts is weighed by the counter and displayed as "940" (g) on the weight display section (2). Next, input `` 50 '' with the numeric keypad switch (5) and press the number setting button (6) .The unit weight display (3) shows `` 1880 '' (mg), and the number display (4) shows `` "50" is displayed. That is, the total weight (940) ÷
The number (50) = unit weight is calculated by the counter, and the result is displayed on the unit weight display unit (3), which is stored in the counter.

After the weight of one part has been accurately measured and set as described above, if a large number of parts to be counted are placed on the tray (8), the total weight of those parts will be displayed on the weight display section (2). While being displayed, this is divided by the set unit weight, and the number of parts obtained as a result is displayed on the number display section (4).

[Problems to be Solved by the Invention]

As described above, the weight counter requires the user to count the number of parts when setting the unit weight of the parts to be counted. In some cases quite a few parts have to be counted. Such an account is not only troublesome, but there is a high possibility of making a mistake in counting, and there is a problem that if the number is forgotten on the way, it is necessary to recount from the beginning.

An object of the present invention is to provide a counter which does not have the above-mentioned troublesome counting and which has no counting error.

[Means for Solving the Problems]

According to the present invention, the above-mentioned object is at least a dish plate,
In a counter equipped with a weight display unit, a unit weight display unit, a number display unit, a number setting button, a weight detection means, a calculation circuit for calculating the unit weight, and a storage circuit, parts are placed on the tray. When the weight detecting means is dropped, a shocking force is applied to the weight detecting means to generate a pulse output, and a counting means for automatically counting the pulse output is built in, and the counting means is made to drop one by one on the pan. In addition to automatically counting the number of parts, the storage circuit stores the output of the counting means and the output of the weight detecting means, and the output of the counting means has reached a sufficient number to set the unit weight. After that, by pressing the number setting button, the output of the weight detection means stored in the storage circuit is output by the output of the counting means stored in the storage circuit. After storing the unit weight obtained by dividing by the calculation circuit in the storage circuit, a large number of parts to be counted are placed on the pan at the same time so that the large number of parts are automatically counted. It is achieved by a counter characterized in that

[Action]

According to the counter configured as described above, it is not necessary to count a large number of parts, and there is no counting error, so that counting can be performed quickly.

〔Example〕

Examples will be described with reference to the drawings. The parts corresponding to those in FIG. 1 are designated by the same reference numerals. In FIG. 2, when the parts to be counted, the bolts (9), are dropped one by one on the pong and the pong and the pan (8),
A shocking force is applied to the load cell to generate a pulse P as shown in FIG. This pulse output is the casing (1)
It is automatically counted by a counter therein, and is stored as a number in a storage unit in the casing (1) and is digitally displayed on the number display unit (4). In addition, the total weight detected by the load cell is also stored in the storage unit, and at the same time, the weight display unit
Digitally displayed in (2). While confirming the number sufficient for setting the unit weight, for example, 50 pieces on the digital display of the number display unit (4), place them on the pan (8) in sequence. Then, when the number setting button (6) 'is pressed, the calculation unit in the casing (1) calculates total weight / number = unit weight, and the result is displayed on the unit weight display unit (3). This is also stored in the storage unit. At the same time, counting by the counter is stopped.

After the weight of one part has been accurately measured and set as described above, if a large number of parts to be counted are placed on the tray (8), the total weight of those parts will be displayed on the weight display section (2). While being displayed, this is divided by the set unit weight, and the number of parts obtained as a result is displayed on the number display section (4).

If you want to continue counting the same type of parts, place it on the pan (8).
All you have to do is repeat the operation of placing the next part on.
Next, if you want to count different types of parts, delete button (7) '
When is pressed, the unit weight stored in the storage unit is erased, and at the same time, the counter is in a state of counting again.

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

For example, the present invention can be applied to general counters without being limited to the embodiments of the illustrated structure.

The shape of the tray (8) may also be configured as a container so as not to jump and drop outside when it is desired to drop a component.

〔The invention's effect〕

As described above, according to the counter of the present invention, when the unit weight is set, the pulse output of the load cell generated when dropping the parts one by one on the pan is automatically counted by the counter. Since the user does not have to count the number of parts and the counting error is eliminated, it is possible to count quickly and accurately.
