Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a parts rack that stores a plurality of parts necessary for assembly, one by one.

(Prior art) For example, on a motorcycle assembly line, each worker is in charge of their own process, but in that case, one worker is only responsible for working on a single model of motorcycle. Rather, for example, it is common to be in charge of all small, medium, and large motorcycles that flow on the same assembly line.

In this way, when one worker is in charge of work on different models, the number of types of parts increases accordingly. A system was adopted in which all the necessary parts were stored in mold parts racks, separated by part type (not by assembly model). Therefore, even parts other than those required in a certain receiving process are always on display, and as a result, there is a risk that the worker may feel the heat and pick up the wrong part or forget to assemble it.

(Object of the Invention) This invention was made in view of the above problem, and aims to prevent workers from mistaking parts or forgetting to assemble them.

(Structure of the Invention) In order to achieve the above object, the present invention provides a plurality of upper and lower stages of disc-shaped component storage shelves in which a plurality of component storage spaces are arranged in the circumferential direction by partition plates, and the storage shelves have the following features: Each stage can be rotated independently around the vertical axis by a separate drive motor, and in the above parts storage space,
The parts needed by the worker are sorted and stored by parts tray, and each drive motor has a parts storage space corresponding to the parts required in the receiving process for each assembly model. By controlling the indexing control means that indexes in series in the vertical direction, only the parts necessary for each holding process are automatically indexed in one vertical line.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a rack pedestal 2 is installed on an installation surface 1, and can be horizontally adjusted by an adjuster 3 whose height is freely adjustable. A fixed receiver 4 is protruded from the center of the upper surface of the rack mount 2, and a vertical rotating shaft 5 is supported by the fixed receiver 4. Support flanges 6 in five upper and lower stages are protruded from the outer periphery of the rotating shaft 5, and each support flange 6 has a driven gear 7 and a disk-shaped component storage shelf 8 located on the upper surface thereof. In this case, each component storage shelf 8 can be individually rotated together with the driven gear 7 for each lower stage by dividing the rotating shaft 5 into upper and lower parts and making it an insertion type.

Here, each component storage shelf 8 includes a bottom plate 8a made of a disk, an outer cylinder 8b projecting upward along the outer circumference of the upper surface of the bottom plate 8a,
The inner cylinder 8C is located on the inner periphery of the outer cylinder 8b on the bottom plate 8a, and as shown in FIG. By arranging the partition plates 8d, a plurality of (16 in the illustrated example) component storage spaces 9 are formed in each component storage shelf 8 in the central direction.

On the other hand, a drive support stand 10 is fixed on the rack frame 2 in a state extending to the back side opposite to the operator side F, as shown in FIG. As shown in FIG. 2, drive support shafts 11 located on both left and right sides when viewed from the operator side F are vertically fixed to the rear end of the drive support stand 10, and each of these drive support shafts 11 , as shown in Fig. 1, has a plug-in structure that is divided into three stages (upper and lower) and allows the number of connections to be changed as necessary.For this reason, the method of changing the number of connections by plug-in can also be applied to the rotating shaft 5. adopt.

A motor support stand 12 and a bearing support stand 13 are protruded from each of the left and right drive support shafts 11, and a drive motor 14 is mounted on the motor support stand 12.
3, a bearing 15 is attached. In this case, each drive motor 14 drives each drive gear 17 via a reduction gear 16, and each drive gear 17 drives each stage of driven gear 7. Here, the worker side F
The three drive gears 17 on the left side when viewed from the worker's side F connect the three driven gears 7 at the top, middle and bottom, as shown in Figure 2, and the two drive gears 17 on the right side when viewed from the operator side F as shown in Figure 1. 2
Drives the driven gears 7 of the 4th and 4th stages.

All the parts necessary for the process that the worker is responsible for are classified and stored in the parts storage shelves 8 of each stage, and the method of storing them will now be explained.

In other words, the vehicle models flowing on the assembly line are M-1 and M-2.
, M-3..., and a certain worker takes out a part on that line. In this case, some of the parts required by the operator for all models are categorized and listed as shown in Table 1 below.

(Blank below C) As shown in Table-1, the parts required by the above worker are:
For all models with receivers, there are 5 types such as bolts, washers, and O-rings, and for each type, bolts are B1,
B2, B8, ..., washers are Wo, W2, W8%
Assume that many types are required, such as..., and there are 80 types in total. These 80 types (16X
5) are stored in each component storage space 9 in five stages for each of 16 types.

When storing them, generally, Bo, B2, B8, etc. in Table 1 are placed on the first stage component storage shelf 8, and the second
Place W-work, W2, W8, etc. on the parts storage shelf 8 in the tier.
Distribute and accommodate up to 5 stages.

In this way, for example, for model M-1, the first stage component storage shelf 8 rotates and the classified Bl (rack (marked on the outer periphery of the cover 18) will correspondingly stop.

At the same time, the second stage component storage shelf 8 rotates in the same manner for the washers, and the classified W1 similarly stops facing the outlet 18a. The other component storage shelves 8 are similarly indexed, and the component storage spaces 9 of B1, Wl, 01, .

As a result, all the necessary parts for model M-1 are lined up vertically and are on standby, while other unnecessary parts are hidden by the rack cover 18. This was determined by the same control for the other models M-2, M-3, etc. at the outlet 18a, but the operator
All you have to do is take out the parts that are displayed vertically depending on the model, so you don't have to make mistakes or forget to take them out.

In this case, each component storage shelf 8 is rotated independently so that each stage is individually indexed. Here, it is also possible to rotate all the component storage shelves 8 integrally at the same angle, but in that case, for example, M-2 and M-3
Assuming that the 0-ring used in the 0-ring is a common part as shown in Table 1, the parts housing space 9 corresponding to the upper part of the bolt 4 and washer W2 not only accommodates the false 0-ring but also the bolt. If the same 02 part is not stored in the parts storage space 9 corresponding to the upper part of the washer W8 and the washer W8, the 02 O ring cannot be taken out with M-3. In this way, if the above-mentioned integral surface rolling type is used, no identical parts
However, in the parts rack according to the present invention, independent indexing control is performed for each stage, so that, for example, M-
When moving from 2 to M-3, the first and second stage component storage shelves 8 should be rotated, and the third stage component storage shelf 8 should be stopped since it contains the same parts. can be controlled,
Therefore, the same parts can be stored in several parts storage spaces 9
There is no need to take the trouble of distributing the product to other users, and the mistakes that tend to occur can be avoided.

Such indexing control by independent rotation of each stage can be performed, for example, by selecting the model-specific selection buttons (M-1, M-2) in Table 1.
,...) outputs a signal for each model, and in response to the signal, a microcomputer with a storage device
This is done by individually controlling the rotation of each drive motor 14 based on the memory corresponding to each machine m (holding process).

The indexing is controlled by the rotational position detection means for each stage as described above. Therefore, the first
A pulley 19 is provided, and a second pulley 21 is provided on a pulley support shaft 2o erected on a drive support stand lo shown in FIG. Switch actuators (not shown) are provided in an arrangement corresponding to the classification display of each stage, and rotational position detection switches 26 are arranged for each stage so as to face each of the actuators to detect the rotational position. Accordingly, each component storage shelf 8 is controlled to rotate to a rotation position corresponding to the model.

(Effects of the Invention) As explained above, according to the present invention, only the parts necessary for each receiving process are automatically indexed in a single vertical line, so that the operator does not pick up other parts by mistake or , there is no need to worry about forgetting to take it. Furthermore, since each stage performs indexing by independent rotation, there is no need to take the trouble of distributing the same parts. Furthermore, since the component storage shelf is disc-shaped, it requires only a small space in the horizontal plane and is compact.
