Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a case for organizing small items for sorting and organizing various items in stores, factory workplaces, etc.

“Conventional technology” Traditionally, parts management on the factory floor was the first priority.
Boxes 32 such as parts boxes, container boxes, tool cases, cassettes, etc. for storing parts of various sizes are placed on the shelf board 31 of a steel shelf 30 on which parts cases as shown in Fig. 1 are placed to organize them. ing. However, the box-like type simply has one part to put the parts in, and it requires many cases and space to store various types of parts, and on top of that, it is simply placed on a shelf. However, since parts were taken out incorrectly or inserted in the wrong place, there was a drawback that product defects were caused by incorrect use of parts.

``The problem that the invention aims to solve'' The causes of product defects can be broadly divided into two types: incorrect assembly and mixing of different parts. Here, if the range of misused parts is not limited at the time it is discovered that a defective part has been mixed in, the damage will spread over a wide range and cause serious damage. For this reason, manufacturing plants are strongly urged to prevent the mixing of old and new parts and to enforce a first-in, first-out system for parts, but this has not been implemented very often. For example, if a part is found to be in short supply during the assembly of a product, the next part to be used will be replenished during free time. The parts being used are placed on the bottom, making it difficult to take them out. Moreover, if the next part is subsequently supplied, various parts will be scattered over a wide area within the case, making it impossible to track down the parts.

Furthermore, it would be fine if the parts to be used next were stored in a case of the same shape and replenished, and the former was placed next to it until it was used, and the used case was replaced. Since it requires space for two cases, if parts are transferred to either case, two types of parts will be mixed and used, resulting in defective products.

In view of the above-mentioned drawbacks, the present invention consists of stacking two or more parts storage cases, storing replenishment parts in the upper part, storing parts currently in use in the lower part, and storing the parts in the upper part. The purpose of this is to prevent parts from being misused by allowing only the lower case to be pulled out, and to manage and organize parts in a narrow space.

``Means for Solving the Problems'' The configuration of the present invention has a rearward upward slope, and a pair of guide portions are provided inside the upper and lower portions and on both sides, through which locking portions to be described later can pass. A unit frame having a locking convex portion on the front side of the bottom plate provided on the unit frame, and locking pieces are provided at both ends of the bottom plate of the unit frame to prevent the unit frame from moving directly or indirectly on the product shelf in the front and back direction. , a stopper that locks on the locking convex portion is provided on the lower surface, and the front surface has a downwardly sloped surface, and the locking portions that engage with the guide portion on both sides are divided into two parts, the front and the rear on both sides, and the lower half. The device is characterized in that the storage cases are inserted from the top of the unit frame and pulled out toward the front of the bottom.

``Function'' By engaging the locking parts provided on the sides of the storage case with the guide parts provided on both inner surfaces of the unit frame, the storage case inserted from above the unit frame can be pulled out only from below. At the same time, when the case is pulled out from below, the case sequentially moves from above to below.

``Example'' An example of the present invention will be described with reference to the drawings.The upper part of a unit frame 3 formed in a U-shape by a pair of side plates 1, 1 and a bottom plate 2 is connected by struts 4, 4, and as needed. The top plate 5 is attached to the upper part of this side plate. Further, at the center of the front part of the bottom plate 2, a locking protrusion 6 is provided to protrude upward in a direction perpendicular to the direction in which the case is taken in and taken out, which will be described later. A pair of fitting holes 7, 7 are provided. 8,8
is a guide portion that projects from the inner surfaces of both side plates of the unit frame, and is located approximately in the middle of each side surface, and the upper surface of this guide portion 8 is provided with an upwardly sloped slope 8a to form a locking step portion 9. , so that a locking portion 24 located at the rear, which will be described later, can be engaged. Furthermore,
At the bottom of the bottom plate 2, there are hanging pieces 11, 1 that hang on the shelf board 31 of the steel shelf 30 as shown in FIG.
A pair of protrusions 13, 13 are provided in the fitting holes 7, 7 of the bottom plate to allow a mounting plate 12 having a mounting plate 12 projecting from the bottom surface thereof to be detachably fitted thereto. In addition, there are hook pieces 11a, 1 on both front and rear ends of the bottom plate 2.
If the mounting plate 1a is directly provided, the mounting plate 12 is not necessary.

Reference numerals 21 and 21 denote cases for storing various parts, and the top surface is open and has both sides, a back surface, and a bottom surface, as well as an inclined front plate 22. Furthermore, at the rear of the bottom surface of this case, the above-mentioned A stopper 23 that engages with the engagement protrusion 6 is provided. On both sides of this case, locking parts 24, 24 are provided, which are divided into front and rear parts and have a height of 1/2 from the bottom, and a space exists between these locking parts 24, 24. The guide portion 8 is engaged within the case 25 so that the case can move up and down. Furthermore, case 21
In order to smoothly put in and take out the case, leg devices 27 may be provided on both sides of the bottom of the case to reduce the frictional resistance of balls, rails, etc.

To explain the operation of this embodiment, when one case 21a is inserted at the front of the unit frame 3 while being locked on the upper surface of the guide parts 8, 8, this case 21a will move along the slope 8a on the upper surface of the guide part. When the rear locking portion 24a is moved backward and then removed from the guide portion 8, the guide portion 8 is located in the space 25 between the two locking portions 24, 24, and the case 21 is moved along the guide portion 8. is downward. case 21
When the case 21 is lowered onto the bottom plate 2 of the unit frame 3, the guide portion 8 is released from the locking portions 24, 24, and when the case 21 is pulled out, the case 21 moves smoothly until the stopper 23 locks onto the locking convex portion 6. (Figure 4). This case 21a is attached to the unit frame 3.
When taking out the case 21b from above, the other case 21b located above is slightly pushed up so that the stopper 23 hangs over the locking protrusion 6, so that the case 21b can be taken out smoothly. Also, pull out the lower case 21a toward you,
When taking out the unit from the unit frame 3, the upper case 21b descends smoothly while the front plate 22 contacts the rear part of the lower case 21a, so that the shock of the fall does not cause the parts to fly out from inside the case. Further, since the fitting hole 7 and the protrusion 7 are engaged with the mounting plate 12 and the bottom plate 2 of the unit frame 3, the unit frame 3 will not come off from the mounting plate 12, and the mounting plate 12 will not come off. The hanging pieces 11, 11 do not come off the shelf board 31 of the steel shelf.

Although this embodiment has been described using a unit frame, it is also possible to apply the present invention to component cases for electronic and electrical small parts such as cassettes and pick cases.

The second embodiment will be explained with reference to FIGS. 9 and 10.
When storing three cases 21 in a unit frame,
The locking parts 24, 24 of the first case 21a at the lower stage do not engage with the lower part of the guide part 8 in the horizontal direction, so that the first case 21a can be pulled out toward the front. Since the guide portion 8 is vertically engaged in the locking portions 24, 24 of the second case 21b located above the first case 21a, the second case 21b can move downward; It cannot be moved horizontally, so it cannot be pulled forward. Once the third case 21c located above the second case 21b is inserted into the unit frame from the front, the third case 21c moves backward along the upwardly sloped slope 8a along the upper surface of the guide portion 8 while its rear part rises. , when the rear locking portion 21 is disengaged from the upper rear end of the guide portion 8 and placed on the second case 21b, this locking portion 24 is attached to the locking step portion 9 provided at the rear upper end of the guide portion 8. As a result, the unit frame cannot be pulled out toward the front. but,
Since the guide portion 8 is engaged between the two locking portions 24, 24, the first case 21a can move downward like the second case. Therefore, among the plurality of cases housed in the unit frame 3, only the bottom case can be pulled out. This prevents various parts from being misused by pulling out the case in various ways.

Incidentally, when inserting the case into the unit frame for the first time, it is of course possible to insert it from below. Furthermore, in the case of large components, it is of course possible to remove the top plate 5, store them from above the unit frame, and take them out from below.

"Effects of the invention" The invention as described above has the following effects.

Since the multiple cases stored in the unit frame are locked by the guide part, they can only be pulled out from below, so there is no need to take out the parts that are stored in the upper case to be used next. Misuse of parts can be prevented.

Even if the lower storage case is pulled out, it is latched by the stopper and will not come out unless the user pulls it out, which prevents parts from being scattered and improves work efficiency.

When the unit frame is placed on a steel shelf, it is possible to prevent the unit frame from falling off the steel shelf.

At least two or more cases can be placed in the space of one case, so a large number of cases can be placed in an organized manner.Furthermore, since there is no need to pull out anything other than the case below the case while it is currently in use, it prevents misuse of parts. parts management can be performed accurately.

Even if you use the free time during work to store replacement parts or parts to be used next in the upper case,
The case cannot be pulled out unless the lower case is pulled out, which prevents parts from being misused, allows proper parts management, and further improves work efficiency.
