Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a storage inspection device used mainly for visually inspecting large bearings for vehicles and the like after being cleaned.

(Prior art) Bearings for vehicles have large diameters and are heavy, so in the latter stages of the manufacturing process, the bearings are usually laid down on their side with their axes facing up and down, and placed stably on a conveyor. Cleaning is done by spraying cleaning liquid from above and below and from all sides.

Finally, the bearings that have been cleaned are subjected to a visual inspection, but since the speed of this inspection is different from the processing speed of a series of manufacturing processes including cleaning, visual inspection is generally not recommended. The inspection location was set apart from the series of manufacturing processes, and the visual inspection was made a separate process from other manufacturing processes.

Additionally, in visual inspection of bearings, the orientation of the bearings had to be changed manually in order to visually inspect the bearings from all directions.

(Problem that the invention aims to solve) However, as mentioned above, if the cleaning process and inspection process are set separately, not only will a large space be required for these processes, but the inspection process will be There was a problem that the overall work efficiency could not be improved because of the network.

In addition, vehicle bearings are quite large and heavy (for example, outer diameter 220 mm and weight 10 to 20 kg), so it takes a lot of effort to manually turn them upside down and lift them. It took time to change the position, and the efficiency of the test itself was low.

The present invention was developed in light of this situation, and it enables visual inspection to be performed quickly and easily, speeds up each manufacturing process up to visual inspection, and improves overall work efficiency. The purpose is to

(Means for Solving the Problems) In order to achieve the above object, in the present invention, the transferred bearing is placed horizontally at the end of the movement path in which the bearing is transferred in a sideways position with its axis facing up and down. A pedestal for tilting from a posture to a standing posture is installed, and a chute for rolling and moving the erected bearing in a predetermined direction is provided on the lower side of the slanted position of the pedestal, and at the end of the chute, A storage table is provided that can be moved in a direction almost perpendicular to the rolling direction of the bearings, and this storage table has a storage section that stores a plurality of vertical bearings that have been rolled and discharged from the chute in a column. Install multiple rows in parallel in the direction,
Further, at the rear of the storage table 11, an inspection table is arranged to receive the bearings rolled and discharged from each storage section between a pair of idle rollers.

(Function) According to the above configuration, the bearing that has been transferred after undergoing cleaning treatment in a horizontal position is once received on the pedestal, and by the tilting of the pedestal, it becomes an upright position and is sent onto the chute. . The bearing on the chute rolls as it is and is fed into the storage section of the storage table. Subsequent bearings are fed into the storage section in the same way, and when a predetermined number of bearings are stored in a column in the storage section, the storage table moves one pitch so that the next storage section faces the chute, and the next storage section faces the chute. Column storage is performed in the section.

In addition, the bearings stored in each storage section in an upright position are taken out one by one onto the idle rollers of the inspection table, and while being rotated freely on the rollers, the inner race, outer race, etc. are visually inspected from both sides. The cleaning condition of the races and bearing rollers is inspected.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the drawings. FIG. 1 shows an overall plan view of a bearing cleaning machine equipped with a bearing storage inspection device according to the present invention, and FIG. 2 shows a side view of the bearing storage inspection device.

The bearings 1 to be cleaned are placed on a carry-in cart 2 in a horizontal position with their axes facing up and down, and set in a carry-in control device 3. The bearing 1 transferred from the carry-in truck 2 to the carry-in control device 3 is fed onto a supply table 4 whose elevation is controlled, and then transferred to the terminal end of a conveyor 6 by a pusher 5.

The conveyor 6 includes a pair of left and right conveyor chains 6.
A and 6a, and the bearing 1 in a sideways posture is stably placed and carried into the cleaning device 7.

In the cleaning device 7, the bearing 1 is slightly lifted up by the conveyor chains 6a, 6a in a positioned state, and is cleaned by spraying cleaning liquid from above and below and from inside and outside, and after cleaning is completed, the bearing 1 is moved again onto the conveyor chains 6a, 6a. The cleaning device 7
It is carried outside and sent to the bearing storage inspection device 8 placed behind it.

This storage inspection device 8 is comprised of a pedestal 9 for changing the bearing posture, a chute 10, a storage table 11, and an inspection table 12.

The pedestal 9 is arranged at the end of the conveyor 6, and has two positions: a horizontal position in which it receives one of the conveyed bearings 1 on its side, and an upright oscillation of approximately 90 degrees around the fulcrum axis P on one side. When the optical sensor 13 detects that the bearing 1 has been carried onto the pedestal 9, the air cylinder 14 is driven to extend and the pedestal 9 stands up. It's starting to oscillate.

The chute 10 is provided on the side of the pedestal 9 on the side of the fulcrum axis P, and is slightly inclined toward the rear. Therefore, when the bearing 1 on the pedestal 9 stands up and is moved onto the chute 10 as the pedestal 9 stands up and swings as described above, the bearing 1 will move backward due to its own weight. Rolling and moving.
In order to ensure reliable delivery from the chute 10, it is preferable to provide a cylinder 22 for extrusion, as shown by the imaginary line in FIG.

The storage table 11 is arranged at the rear of the chute 10 in a direction perpendicular to the chute 10;
In other words, it is configured to be able to reciprocate in the left and right direction, and has a storage section 15 on its top that stores a plurality of bearings 1 (four in this example) that have rolled and moved from the chute 10 in a vertical row. A plurality of rows (four rows in this example) are provided on the left and right sides. The bottom surface of each storage section 15 is formed into a gently sloped surface that continues to the end of the chute 10, and a stopper 1 is provided at the lower end of the slope to prevent the bearing 1 from falling off.
6 is provided. In addition, at the bottom of the entrance side of each storage section 15, the final bearing 1 stored in tandem is installed.
A sensor 17 is provided to detect the presence of the bearing 1, and when the sensor 17 detects the presence of the bearing 1 for a set time (a time longer than the bearing passing time), the storage section 15 stores the bearing 1,
... is determined to be full, and the electric motor 18 slides the storage table 11 one pitch in the left and right direction, and sets the adjacent empty storage section 15 opposite to the chute 10. By repeating these operations, the bearings 1 are sequentially stored in each storage section 15.

The inspection table 12 is arranged so as to face the rear end of the storage section 15, and has an idling roller 19 on its upper surface.
A group is provided. During bearing inspection, the stopper 16 of the storage section 15 facing the inspection table 12 is pressed by pressing the foot pedal 20.
By retracting the rear end bearing 1 downward,
is rolled and discharged from the storage part 15 and transferred onto a pair of idle rollers 19, where the cleaning condition of the inner race, outer race, and bearing roller is visually inspected from both sides while freely rotating the bearing 1. After the bearing 1 has been inspected, it is transferred to the carry-out cart 21 for the next processing step. Note that each time the bearing is removed from one storage section 15, the storage table 11 is transferred one pitch at a time.

(Effect of the invention) As explained above, the bearing storage inspection device according to the invention stands up the bearings that have been transferred in a horizontal position on the pedestal, and then transfers them to each storage section of the storage table via the chute. The bearings are sequentially stored in a column, and the stored bearings are received on the idle roller 19 of the inspection table so that the bearings in the upright position can be visually inspected, so the following effects can be expected. .

(1) Since the cleaning process and the visual inspection process are combined as a series of lines, the space required can be reduced compared to when each process was set up separately, and the inspection Since there is no need to transfer or store bearings, the time required to complete an inspection can be shortened and work efficiency can be improved.

(2) There is no need to manually flip or lift a bearing in a horizontal position for visual inspection, and the bearing in an upright position can be easily and freely rotated on the idler rollers of the inspection table. Each part can be visually inspected quickly and easily, the effort and time required to change the bearing position is extremely reduced, and the work efficiency of the inspection itself is greatly improved.

(3) Since the transported bearings are stored on a storage table and inspected, by accumulating an appropriate number of bearings on the storage table, each manufacturing process leading up to the inspection, especially the cleaning process, can be carried out. It is possible to absorb the time lag between the speed of This also helps speed up the entire manufacturing process.
