Description

[Detailed description of the invention] This invention improves and rationalizes inspection efficiency by making it possible to perform a series of inspections regardless of the traveling direction of the vehicle being inspected, for example in an automobile repair shop equipped with various inspection devices. This invention relates to an inspection line for automobiles, etc.

2. Description of the Related Art Automobile maintenance shops and vehicle inspection stations are equipped with various inspection devices for measuring the performance of automobiles, and these inspection devices are usually arranged in tandem along the route of the vehicle being inspected. For example, Fig. 1 shows an example of the deployment of various inspection devices in a final inspection site where vehicles are inspected after completion of maintenance. A meter tester 6, a test lift 7, a side slip tester 8, and a headlight tester 9 are installed, and brake tests,
Each test was performed in the same order as the speedometer test.

However, in this conventional inspection line, the brake tester 5 and the headlight tester 9 are structurally equipped with only a single measurement direction. As a result, in the conventional example described above, it is possible to inspect only the vehicle to be inspected 10 that enters in the direction of the upward arrow in FIG. The disadvantage was that it was not possible to

In a conventional automobile repair shop with a shared completion inspection site equipped with such a completion inspection site 1, as shown in FIG. A completion inspection site 1 is arranged approximately opposite the divided maintenance workshop 14, and a vehicle 10a to be inspected before maintenance enters the completion inspection site 1 along the direction of the arrow in the figure, and is subjected to an acceptance inspection at this inspection site 1. After receiving the inspection, the inspected vehicle 10b moves to the maintenance workshop 14 and undergoes individual maintenance.The inspected vehicle 10b, which has completed the maintenance, enters the completion inspection facility 1 again and undergoes a completion inspection, and then moves along the direction of the upward arrow in the figure. They were forced to move around.

Therefore, in this case, movement of the vehicle within the repair shop 12 is limited to one direction, and the movement of the vehicle becomes extremely inflexible.

For example, since all vehicles 10a and 10b are forced to enter through entrance 3, if they are concentrated,
The vehicles waiting to enter are located around the entrance 3, blocking the passage around the entrance, causing traffic congestion and lowering inspection efficiency, and obstructing the use of the maintenance workshop 14 around the entrance 3. However, if this is maintained at a maintenance workshop 14 far away from the entrance 3, the vehicle 10b must be moved all the way to the entrance 3, which increases the congestion of vehicles and also reduces the number of vehicles in this crowded area. People disliked moving because it was unsafe and prone to accidents.

The present invention eliminates these conventional drawbacks, provides bidirectionality to the inspection direction of inspection equipment installed in automobile repair shops, etc., and enables predetermined inspections to be performed regardless of the traveling direction of the vehicle being inspected. The purpose of this invention is to provide an inspection line for automobiles, etc. that can improve maintenance work and inspection efficiency and ensure the safety of this type of work.

For this reason, the inspection line for automobiles, etc. of this invention is
In an automobile inspection line equipped with a hedlight tester, a brake tester, and a speedometer tester, these testers are arranged in tandem along the path of the vehicle being inspected, and the measurement direction of each tester is The system is characterized by being bidirectional, allowing testing to be performed freely depending on the direction of travel of the vehicle being inspected.

It is configured to measure the deflection of the optical axis of the headlight and the luminous intensity. These two headlight test machines 24 and 25 are arranged apart from each other, and each has a measuring direction opposite to the other. The vehicle to be inspected 31b after maintenance is measured by the other headlight tester 25. However, in this case, if the measurement section is configured to be rotatable by, for example, 180 degrees or more, and the measurement direction is bidirectional, a single testing machine can detect vehicles to be inspected approaching from both directions. This means that the headlight test of 31a and 31b can be performed.

The side slip tester 26 has bidirectionality in its measurement direction, as is the case with known devices, and allows the vehicle to be inspected 31a, 3 to pass on the footboards 32 spaced apart from each other on the left and right.

For convenience, the case of the rear wheel is illustrated. Note that, except for the above-mentioned composite test device 28, each test device and its accompanying accessories are the same as those known in the art.

When inspecting a vehicle to be inspected using the inspection line of the present invention configured as described above, the vehicle to be inspected 31a that has not yet been serviced and has entered the automobile repair shop 15 from the road 16 is shown by the solid line in FIG. After passing through the side entrance 17, the vehicle directly enters the completion inspection site 20 and undergoes an acceptance inspection. In other words, completion inspection site 2
The vehicle 31a to be inspected enters from the entrance 21 in the direction of the top arrow in FIG. After taking the test, test lift 27
The front and rear of the vehicle are lifted and the steering suspension, wheel bearings, tire brakes, muffler, etc. are inspected. Next, the vehicle 31a to be inspected stops at a predetermined position in front of the headlight tester 24 and undergoes a headlight test. At this time, the headlight testing machine 24 is normally moved to the position shown in the figure so as not to obstruct the progress of the vehicle, but during the test, these rails 29
It moves left and right along the line and moves up and down to form a predetermined test condition. After undergoing this headlight test, the vehicle 31a to be inspected is subjected to a brake test and a speedometer test in the composite test device 28.

When performing a headlight test using the composite test device 28, the vehicle to be inspected 31a is boarded in advance from the direction of arrow A in FIG.
As shown in the figure, after placing the brake roller 36 and the speed roller 42 on top of the brake roller 36 and the speed roller 42, the left and right drive motors 33, 33 are started.
44 is driven, and the brake rollers 36, 36 are rotated.
As the brake rollers 36, 36 rotate, the sprockets 40, 40, which are fixed coaxially with the axis of the roller 36, rotate, and the rotational force is transmitted to the other sprocket 44, 40 through the chains 53, 53. 44, this sprocket 44,
44 rotates. Therefore, this sprocket 4
Before and after the rotations of 4 and 44, the clutch 47 is moved to the upper right in FIG.
By meshing with the dogs 52 of 4 and 44, the rotational force of the sprockets 44 and 44 is transferred to the speed rollers 42 and 4.
2 to the shaft supporting the speed roller 42,
42 is rotated in the same direction and at the same speed as the brake rollers 36, 36. In this case, the electromagnetic clutch 62 is disconnected and the shafts of the speed rollers 42, 42 are separated. Under such conditions, the brakes of the vehicle 31a are operated, and the wheels 63, brake rollers 36,
The reaction force of the braking force generated between the deceleration mechanism 3 and
4, 34 and brake measuring mechanisms 55, 55, and reading this using brake meters 57, 57. In this case, since the sprocket 43 cannot form a meshing relationship with the clutch 47, the speed roller 42 and the shaft are in an idling state relative to each other, and the rotational force is not transmitted to the other sprocket 42, resulting in deceleration. No load is applied to the mechanism 35.

Next, when performing a speedometer test, the vehicle to be inspected 31a is held in the above-mentioned test state, and the electromagnetic clutch 62 is operated to connect the shafts of the left and right speed rollers 42, 42, and the clutch 47 is Keep it neutral. and,
When the vehicle to be inspected 31a is driven under this condition and its wheels 63 are rotated, the outer rollers 36a of the brake rollers 36, 36 that are in contact with the wheels 63,
36a rotates following the wheel 63 due to frictional force, but the rotational force is generated by the one-way clutches 38, 3.
8, the external rollers 36a, 36a are not transmitted to the shafts of the brake rollers 36, 36.
is in an idling state relative to the internal rollers and continues to spin idly. Therefore, sprocket 40,
40 does not rotate, and no load is applied to the speed reduction mechanisms 34, 34. On the other hand, brake rollers 36,3
6, the speed roller 42 in contact with the wheel 63 rotates following the wheel 63 due to the frictional force between them, but since the clutch 47 is placed in the neutral position as described above, neither The sprockets 43 and 44 cannot rotate either, and only the two shafts connected to the electromagnetic clutch 62 rotate, and the left and right speed rollers 42 and 42 rotate synchronously. Therefore, the speedometer generator 58 attached to the shaft end of the speed roller 42
This generates an electromotive force proportional to the number of rotations of the speedometer 59 and displaces the pointer of the speedometer 59, so all you have to do is read this.

The inspected vehicle 31a that has completed various acceptance inspections in this way is then transported from the entrance 22 to the completion inspection site 2.
0, and is stored in a suitable maintenance workshop 19, where it undergoes individual maintenance and inspection depending on the results of the acceptance inspection.

Next, inspected vehicle 31b underwent a prescribed maintenance inspection.
The vehicle starts from the maintenance workshop 19, enters the completion inspection facility 20 through the entrance 22 as shown by the chain line in FIG. 3, and undergoes a brake test, speedometer test, headlight test, test lift test, and side slip test. That is, the vehicle 31b to be inspected enters the composite testing apparatus 28 from the direction of the upper arrow B in FIG. 5, and the wheels 63 are positioned above the brake rollers 37, 37 and the speed rollers 42, 42 as shown in FIG. First, when performing a brake test, the drive motors 33, 33 are rotated in the opposite direction to that during the above-mentioned acceptance inspection, and the brake rollers 37, 37 are rotated via the deceleration mechanisms 35, 35.
As the brake rollers 37, 37 rotate, the sprockets 41, 41 fixed coaxially with the brake rollers 37, 37 rotate, and the chain 5 also rotates.
4, 54 to the other sprocket 43, 43
Since the clutch 47 rotates, if the clutch 47 is moved in the direction of the sprockets 43 and 43 by the shift mechanism in advance and the dogs 49 and 51 of both are engaged with each other, the rotational force of the sprockets 43 and 43 will move the clutch 47 and the spline 48. The signal is transmitted to the speed rollers 42, 42 via the signal, and the rollers 42, 42 rotate. Even in this case, sprocket 4
4 and 44 are disengaged from the clutch 47, so they do not rotate, and the subsequent brake test is conducted in the same manner as the above-mentioned acceptance inspection.

Next, the speedometer test was performed on the vehicle to be inspected 31b.
is held in the same position as the brake test described above on the composite test device 28, and the test is carried out in the same manner as in the above-mentioned acceptance inspection. Thereafter, the vehicle to be inspected 31b moves along the passage, and after passing the Hedrite tester 24 located in the middle of the passage 23, the test lift 27, the side slip tester 26, and the Hedrite tester 25.
After undergoing a predetermined inspection similar to the above-mentioned acceptance inspection, the vehicle exits the completion inspection site 20 through the entrance 21 and exits the automobile repair shop 15 through the side entrance 17.

Therefore, the vehicle to be inspected 31 that undergoes the acceptance inspection
When the vehicle 31a and the vehicle 31b to be inspected undergo a final inspection, these vehicles 31a, 3
1b can enter from the nearest entrance/exit 21, 22, so there is no need to move the vehicle 31b after maintenance to a distant entrance each time as in the past, and the shortest distance to the entrance/exit 21, 22 can be selected as appropriate. This provides flexibility in vehicle movement and allows this type of inspection to be carried out smoothly and rationally.

Furthermore, since the vehicles to be inspected 31a and 31b enter the completion inspection site 20 through separate entrances and exits 21 and 22, respectively, the vehicles to be inspected 31a and 31b enter the completion inspection site 20 through separate entrances and exits 21 and 22, respectively.
31b can avoid situations where both parties are concentrated at one entrance, thereby preventing collision accidents, etc., which improves the safety of vehicle inspection and maintenance. Maintenance workshop 19
It is possible to prevent the situation where the entrance/exit is blocked by a vehicle waiting to enter and the use of the entrance/exit is obstructed.

FIG. 9 shows an example of application of the present invention, in which the same reference numerals are used for components corresponding to those of the previous embodiment. In this embodiment, the final inspection site 20 is located facing the road 16 of the automobile repair shop 15, in order to shorten the entry and exit routes to the final inspection site 20, and to further increase the effective use of the factory site. It is characterized by the fact that In the figure, 64 is a vehicle parking lot, 65 is a centralized maintenance facility, and the inspected vehicles that have undergone acceptance inspection are sorted into a maintenance workshop 19 and a centralized maintenance facility 65, as shown by chain lines, according to the inspection results.
The inspected vehicle that has undergone the maintenance inspection here enters the completion inspection site 20 as shown by the solid line and undergoes the completion inspection.

In addition, in the above-mentioned embodiment, various testing machines in the completion inspection site 20 were arranged as shown in the figure, but this is just one example, and the present invention is not limited thereto. Furthermore, although the aforementioned drive motor 33 is configured to operate only one of the speed reduction mechanisms 34 and 35 when it is started, it is not limited to this example, and both speed reduction mechanisms 34 and 35 can be operated simultaneously. It is also possible to use a so-called dog clutch configured as shown in FIG. However, it is also possible to use an electromagnetic clutch, for example. Furthermore, in the above-described embodiment, the brake test and the speedometer test were performed using a single composite test device 28; however,
Instead of this testing device 28, it is also possible to use, for example, two brake testing machines and two speedometer testing machines each having a single measurement direction and arranging them in opposite directions. In addition, although the above-mentioned example explained the case where this invention was applied to a four-wheeled vehicle, it is applicable not only to this example but also to the test of two-wheeled vehicles, such as a motorcycle.

As described above, the inspection line for automobiles, etc. of the present invention provides bidirectionality to the measurement direction of the headlight tester, brake tester, and speedometer tester array, and allows testing to be performed freely according to the traveling direction of the inspected vehicle. This makes it possible to carry out the specified inspection smoothly and rationally regardless of the direction in which the vehicle is traveling.
The unreasonableness of having a single entrance/exit and restricting the movement of inspected vehicles to one direction; and because of this, inspected vehicles concentrate at the entrance, blocking the passage around the entrance, resulting in congestion of the vehicles. It is possible to prevent vehicle collision accidents, etc., and improve the safety of vehicle inspection and maintenance work by avoiding situations that encourage the use of the repair shop or obstruct the use of the repair shop. It has a practical effect that is suitable for vehicle inspection stations.
