Description

[Detailed description of the invention] The present invention relates to a parts picking device.

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

When counting parts (of the same type) using the above digital counter, the unit weight of the parts must be calculated. Generally, the weight of the parts to be counted is very small, e.g. 2f
It is as follows. However, the minimum weight scale of a counter is generally 1 t or 21, which cannot accurately measure the entire weight of a single part. Further, even if the weight of the part to be counted is, for example, 22 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 by the digital counter, all users of a large number of parts count and set the average weight of each part. For example, user U counts 50 parts, and the counter plate has 0 parts.
Put it on. Then, the total weight of the parts on the open side is counted by the counter, and the weight display section (2) shows r940J (f).
) is displayed. Next, press the numeric keypad switch (5)!
l) r50J? l-input and press the number setting button (7), the unit weight display (3) K is r188
0J (■), and "5o" is displayed on the number display section (4). That is, with the above operation, the total weight (940) ÷ number of pieces (50) = unit weight is calculated on the counter, the result is displayed on the unit weight display section (3), and this is stored in the counter. .

After the weight of one part has been accurately measured and set as described above, when a large number of parts to be counted are placed on the tray Q, their total weight will be displayed at the bottom of the weight table (2). At the same time, this is divided by the set unit weight, and the resulting number of parts is displayed on the number display section (4).

On the other hand, recently, a parts storage device (c) as shown in FIG. 2 has been developed. In the figure, various parts are housed in the casing (6) and are transported by an endless chain conveyor α4 arranged vertically as shown by imaginary lines. An opening for taking out parts is formed in the lower front part of the casing (2), and from this opening the table (2) is opened.
Construction is underway to take out the container upper weir 9 containing PJTW parts to D. A large number of racks are layered on the chain (c), and each rack (g) is equipped with a container α4 (to) containing all different types of parts. For example, a large number of bolts, nuts, and transistors are stored in each of the containers Q25 (to) 4. To call such a part to the position shown in the figure, operate the code number all numeric keys switch (141), then the chain conveyor (2)
is driven in the direction of the arrow or in the opposite direction to bring into the opening (2) the rack aO which is placed over the container containing the part. The code number of the called part is displayed on the display.

Take out the container containing the desired parts from the parts storage device (c) above and place it on the table 12D. A desired number of parts is counted by placing them on the tray aη of the digital counter shown in FIG. As mentioned above, this work is very troublesome, and the work efficiency is low because each part is set one by one.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an entire parts picking device that can improve work efficiency. This purpose, according to the present invention, includes a parts storage device that stores a plurality of types of parts and calls the desired parts to a predetermined position by operating an all parts selection switch or a numeric keypad switch; A parts picking device comprising: a digital counter equipped with a tray; a unit weight for each of the plurality of types of parts is stored in advance; This is accomplished by a parts picking device characterized in that upon operation, the unit weight of the desired part is read out and the digital counter is automatically set.

Hereinafter, embodiments of the present invention will be described with reference to FIG. Note that parts corresponding to FIGS. 1 and 2 are given the same reference numerals.

The parts picking device of this embodiment consists of a parts storage device (c) and a digital counter t41 whose appearance is similar to that shown in FIG. 2, but the digital counter is different from the digital counter shown in FIG. 5) and number setting button (7)
] has been omitted.

The parts storage device (c) accommodates many types of parts, and has a built-in unit weight storage circuit that stores the unit weight of each part in association with its code number. Therefore, the unit weights of various parts are measured in advance.

For example, let's say that you want to call up the opening 0 for taking out the parts of the container atnc in which it is stored. To do this, operate the bolt code number, for example l 321j', using the numeric keypad switch α. Then, the internal chain conveyor is driven, and the rack (2) on which the containers are arranged is brought to the desired position.

The unit weight of the bolt is read out from the unit weight storage circuit at the same time as the above numeric key switch A41 is operated. The weight is supplied to the unit and stored therein, and is displayed as, for example, r1880J (Illg) on the unit weight display section (3).

That is, according to the present invention, when the code number of a desired part is operated on the numeric keypad switch σ, the unit weight of that part is automatically displayed on the digital counter (401).
is set within. Therefore, there is no need to count a large number of parts, place them on the plate Qυ, and set the total unit weight. For this reason, the number setting button and ten key switch can be omitted as shown in the figure.

If you pull out the container α7) onto the table (2Il), take out a large number of containers from it and place them on the plate C1υ,
Thereafter, the weight and number of pieces are immediately displayed on the weight display section (2) and the number display section (4). If you want to increase or exceed the desired number of grapes, just adjust the amount on the number display section (4) while looking at the grapes on the plate.

Next, if you want to take out the desired number of all other types of parts, press the erase button (8) to erase all the displayed values in the unit weight display section (3), and then select the coat number of the part using the numeric keypad switch. With one operation, all the parts are brought to the rack tH-1JEVA product removal opening disposed on the container in which they are stored.The unit weight of the parts is automatically set in the digital counter t40.

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

For example, in the above embodiment, the total unit weight setting W11 of various parts is provided in the parts storage device, but instead of this, it may be provided in the digital counter.

As described above, according to the parts picking device of the present invention, it is possible to further improve the efficiency of picking out a desired number of desired parts.
