Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a parts management device that can easily know that the number of parts stored inside a parts box is insufficient than the appropriate inventory. It is.

[Prior Art] A conventional parts management device will be explained with reference to FIG. For example, the angle shelf 10 has a height of 180 cm,
The width (the width of one unit of the angle shelf 10) is 120 cm, and the shelf 12 has multiple stages (for example, 6 to 7 stages),
Multiple pieces can be arranged horizontally. The parts box 14 is a rectangular parallelepiped box with an open top, and is placed on the shelf 12. Each parts box 14 contains one type of parts, and a label 16 indicating the type of parts stored in the parts box 14 is pasted on the front of the parts box 14. For example, 6 to 8 boxes 14 are placed on each shelf 12 of one unit of angle shelves 10.
pieces are arranged.

In conventional parts inventory management using such a parts box 14, when shipping parts, a person looks inside the parts box 14 and issues a replenishment instruction slip based on the sense that the number of parts has been reduced by almost half. Furthermore, in parts inventory management using a periodic patrol system, each parts box
4 from the shelf 12, the number of parts in each parts box 14 is checked, and based on the result, an instruction to replenish the parts is issued and the parts are replenished.

[Problems to be solved by the invention] In conventional parts inventory management using the parts box 14, the person in charge may overlook the fact that the number of parts in the parts box 14 is halved when shipping parts, or generate a slip for replenishment instructions. It's easy to forget, and it's easy to not be able to replenish your supplies in time. In addition, in the periodic patrol system, it is necessary to pull out all the parts boxes 14 (for example, several thousand boxes in one business) from the shelves 12 and look inside them, which requires an enormous amount of time and effort.

The object of this invention is to provide a parts management device that can easily manage the inventory of a large number of parts, and can immediately recognize when the number of parts in stock falls below the appropriate number.

[Means for solving the problem] According to the parts management device of this invention, the parts shelf 3
Multiple parts boxes 20, 20 placed on 3, 56
b, 20c, box bodies 22, 22b, which are divided into two chambers in the front and rear direction via a partition 24,
Support points 36, 58 for swingably supporting the box bodies 22, 22b, 22c are formed on the lower surface of the box 22c at approximately the center in the front-rear direction, and parts materials are placed in one of the two chambers 26, 28. 30 in the other chamber 28
Insert the set weights 32 into each of the box bodies 22, 22b, 22c, and check the remaining amount of the component material 30.
A parts management device is provided which is characterized by being provided with an alarm device 41 that detects the inclination of the parts.

[Function] In a parts box in which the number of parts and materials stored in one chamber exceeds the lower limit of the appropriate number, the total weight of the parts and materials in one chamber is heavier than the set weight in the other chambers, The first chamber side of the box body is tilted downward with respect to the fulcrum.

However, when the number of parts and materials in one chamber decreases due to shipping, and the number of parts in the parts box falls below the appropriate inventory, the total weight of the parts and materials in one chamber is lighter than the weight set in the other chambers. Then, the box body swings about the fulcrum and tilts the other chamber side downward.

Therefore, in a parts box where the box is tilted with one chamber side down, the number of parts and materials in stock is greater than the lower limit of the appropriate inventory quantity, and the box body is tilted with the other chamber side down. In the parts box currently in stock, the number of parts and materials in stock is less than the appropriate stock number. This inclination of each parts box is indicated by lighting of a warning lamp in the alarm device, and the alarm device immediately determines which parts require replenishment.

[Example] Hereinafter, this invention will be described with reference to an example of the drawings.

In FIG. 1, the parts box 20 includes a substantially rectangular parallelepiped-shaped box 22 whose upper part is open.
The box body 22 is open obliquely forward at the upper front surface, so that parts can be easily taken in and out of the box body 22 from the upper front surface. Division part 24
The box body 22 is
The interior of the box body 22 is divided into a front chamber 26 as one chamber and a rear chamber 28 as another chamber.
The front and rear slopes of are directed toward the front chamber 26 and the rear chamber 28, respectively. One parts box 20 is prepared for each type of parts, and parts 30 as part materials are placed in the front chamber 26.

The weight 32 is set to have a weight equal to the lower limit of the appropriate stock number of parts 30 placed in the front chamber 26 and placed in the rear chamber 28 . parts shelf 3
3 is provided with a plurality of shelf surfaces 34 parallel to each other. A fulcrum 36 having a semi-circular cross section is fixed at approximately the center of the shelf surface 34 in the front-rear direction with its convex surface facing upward, and the lower surface of the parts box 20 approximately at the center in the front-rear direction is placed on the upper part of the fulcrum 36. The fulcrum 36 may be integrally fixed to the lower surface of the parts box 20 approximately at the center in the front-rear direction with the convex surface facing downward.

The alarm device 41 is composed of a power source 38, a limit switch 42, and an alarm lamp 40, and the power source 38 uses an outlet terminal for a power line provided near the parts shelf 33. Alarm panel 39
is attached to, for example, the side surface of the parts shelf 33, and is equipped with a plurality of alarm lamps 40. Each alarm lamp 40 is provided corresponding to the parts box 20 placed on the parts shelf 33.
A number is displayed near each alarm lamp 40 so that it can be easily determined which parts box 20 each corresponds to. The limit switch 42 is provided on the shelf surface 34 at a position below the rear end of the lower surface of the box 22, and is opened and closed by contact with the lower surface of the box 22. Power supply 38, alarm lamp 40 and limit switch 4
2 are connected to each other in series to form an electrically closed loop.

FIGS. 2a and 2b show the parts box 20 in an inclined state. When the number of parts 30 in the front chamber 26 is equal to or greater than the lower limit of the appropriate stock quantity, the total weight of the parts 30 in the front chamber 26 is heavier than the weight of the weight 32 in the rear chamber 28, and the parts box 20 is Figure 2a
It is tilted so that the front chamber 26 side is facing down. Therefore, limit switch 42 is turned OFF.
state, the alarm lamp 40 is not energized and is off. On the other hand, as the parts 30 are shipped, the number of parts 30 in the front chamber 26 decreases, and when the lower limit of the appropriate inventory is reached, the total weight of the parts 30 in the front chamber 26 is greater than that in the rear chamber 26. The weight becomes lighter than the weight 32, and the parts box 20 tilts so that the rear chamber 28 side faces down, as shown in FIG. 2b. Therefore, the limit switch 42 is turned on, and the alarm lamp 40 is energized and turned on. In this way, by checking the lighting status of the alarm lamp 40 on the alarm panel 39, the person in charge can
It is possible to immediately recognize which parts box 20 is out of stock and whether parts 30 need to be replenished.

FIG. 3 shows another example of the parts box. The rear chamber 28 of the box body 22b of the parts box 20b is not provided with a side wall, and the weight 32 is fixed to the bottom surface of the rear chamber 28 and is visible from the side.

Figure 4 shows a parts box 20 and parts boxes 20b and 20c.
4 is a plan view of an imbalance detection switch 44 as a detection device for detecting that the rear chamber 28 is tilted so that the rear chamber 28 side is facing down. Imbalance detection switch 44
is attached to the bottom of the parts box 20, etc.
0 or swings integrally with the parts box 20b. Band 4
6a and 46b are parts boxes 20 at a predetermined interval.
Alternatively, it extends parallel to each other in the front-rear direction of the parts box 20b, and consists of an insulating part 48 and a conductor part 50 in the extending direction, and terminals 52a and 52b are connected to each conductor part 50 of the bands 46a and 46b. .
The steel ball 54 as a moving body is connected to the bands 46a and 46b.
having a diameter larger than the gap between the bands 46a,
46b and rolls along the strips 46a, 46b in relation to the inclination of the strips 46a, 46b. When the parts box 20 and the parts box 20b are tilted with the front chamber 26 side containing the parts 30 facing down, the steel balls 54 are in the position of the insulating part 48, and the bands 46a and 46b are electrically disconnected. The imbalance detection switch 44 is in the OFF state. In contrast, the parts box 20 and the parts box 20
When b is tilted with the rear chamber 28 side facing down, the steel ball 54 is in the position of the conductor part 50, and the bands 46a,
46b are electrically connected to each other via the steel ball 54, and the imbalance detection switch 44 is
It is in ON state. By using this imbalance detection switch 44 in place of the limit switch 42, the alarm lamp 40 can be turned on depending on the inclination of the parts box 20 and the parts box 20b.

In FIG. 5, the vertically elongated parts shelf 56 is not provided with shelves as tiers, and the parts box 20c has a substantially rectangular parallelepiped-shaped box body 22c with an open upper part that rotates via a shaft 58 serving as a fulcrum. It is supported by a parts shelf 56. The shaft 58 is fixed to the box body 22c so as to protrude laterally from the side wall of the box body 22c at the center position of the box body 22c in the front-rear direction.
6, or is fixed to the side wall of the parts shelf 56, and penetrates through the compartment 24 of the box body 22c to rotatably support the box body 22c. Since this parts shelf 56 does not have a shelf surface that supports the parts box 22c, it is not possible to detect which side the parts box 20c is tilted to by the limit switch 42 in FIG.
This can be detected by the imbalance detection switch 44 shown in the figure. Inside the parts shelf 56, stoppers s that can be abutted at the front and rear of the parts box 20c are installed to prevent the parts box 20c from tilting too much, and it is also possible to attach a limit switch to a part of this stopper.

[Effects of the invention] As described above, according to this invention, the parts box containing the parts material swings according to the number of parts materials in the parts box, and the number of parts materials is adjusted to the appropriate inventory level. If it is above the lower limit, tilt so that the first chamber side is facing down, and when the number of parts and materials is less than the appropriate inventory number, tilt so that the other chamber side is facing down,
Since the detection device is activated in relation to this inclination of the parts box, it is possible to immediately recognize from the display on the alarm device which parts box has less than the appropriate number of parts in stock and must be replenished. I can do it. Therefore, it is possible to prevent out-of-stocks due to forgetting to check the number of stocks in stock or to give replenishment instructions when shipping parts, and it is also possible to omit a complicated periodic patrol inspection that looks into the inside of all parts boxes one by one.
