Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a device that detects when the amount of cleaning solution in the solution tank of a car wash machine has decreased below a certain level. It is.

[Conventional technology]

A washing machine that washes a vehicle must move forward and backward while straddling the vehicle that is stopped at a predetermined position, so solutions such as detergent and wax for cleaning must be placed inside the washing machine. . In order to prevent this solution from decreasing and interfering with the next cleaning action, it is necessary to detect when the remaining amount of the solution is below a certain level and display it externally.

A conventional solution remaining amount detection device connects the lower end of a lifting rod to a float installed in a solution tank.
In some cases, the upper end of the lifting rod extends above the solution tank.

When the lifting rod descends to a predetermined position due to a decrease in the amount of cleaning solution, a detection switch installed at the top of the solution tank is activated by an appropriate actuating piece on the lifting rod, indicating that the remaining amount of solution has reached its limit. is detected.

In the conventional detection device described above, the detection device is installed in the solution tank itself, so
When replacing an empty solution tank with another filled solution tank, the detection device must be attached and detached, which is troublesome.

Therefore, as another device for detecting the remaining amount of solution, multiple solution tanks containing solvent and wax are placed on a support stand, and the four corners of this support stand are supported by extensible springs. Some solutions are designed to operate a detection switch at an appropriate position on the support base to detect a lack of remaining solution when the support base rises to a predetermined position.

[The problem that the idea attempts to solve]

However, in this residual amount detection device, a tank containing the solvent and a tank containing the wax are placed on the support base, and the total weight of both is detected. Therefore, even if the remaining amount in one solution tank is below a predetermined value, if there is a large amount of solution in the other solution tank, the detection device will not operate, which will hinder cleaning. There is.

An object of the present invention is to provide a cleaning solution remaining amount detection device that eliminates the above-mentioned drawbacks.

[Means to solve the problem]

According to the present invention, the above-mentioned purpose is to create a car wash machine body that has left and right legs that are parallel to each other and can move back and forth across the vehicle, and a box-shaped machine that is long in the front and back direction and has an open top. None, and includes a pedestal provided at least on one of the legs, and a plurality of solution tanks arranged in the pedestal in the front-rear direction and containing a cleaning solution such as cleaning liquid or wax. In a car wash machine, there is a proximity switch fixedly installed at an appropriate height between the solution tanks with the detection surface facing left and right, and a proximity switch installed facing left and right at approximately the same height as the proximity switch. , the detection plate provided at the free end is located near the bottom of the proximity switch, and the base extending beyond one side of the solution tank has an axis that is horizontal to the stationary member that is integral with the pedestal. A detection member pivotally mounted at the lower part of the middle part of this detection member,
The outer end is pivotally connected to a horizontal axis facing in the front-rear direction,
and a rotating member whose free end extending inward is given a rotational habit in an upward direction; Extending below the detection member,
The rising part provided at the other end is provided with an operating member that presses against the inner surface of the solution tank due to the rotational behavior of the rotating member, so that the cleaning solution in the solution tank remains at a certain level. When the following is reached, the operating member is rotated to tilt the solution tank, and in conjunction with the rotation, the detection plate is opposed to the proximity switch, thereby detecting the remaining amount of cleaning liquid. This is achieved by doing this.

〔Example〕

Hereinafter, the configuration of the present invention will be explained with reference to an illustrated embodiment.

In FIG. 1, an upper plate portion 1a of a washing machine 1 has a rectangular shape that is elongated in the left-right direction, and is supported by left and right leg portions 1b and 1c that are parallel to each other. The legs 1b, 1c are movable on the rails 2, 3 in the front-rear direction indicated by arrows 4 and 5 via rollers (not shown).

The washing machine 1 cleans with detergent and finishes with wax while moving astride a vehicle (not shown) that is stopped at a predetermined position between the rails 2 and 3.

On the bottom plate 6 of the left leg 1b, a box-shaped pedestal 7 that is open at the top is attached with its long sides facing in the front-rear direction.

As shown in FIG. 2, within the frame 7, a plurality of solution tanks 8 and 9 are placed side by side in the front and back direction with an interval between them.
A detection device, generally designated by the reference numeral 11, is arranged between 9 and 9.

Solution tanks 8, 9 and outer and inner plates 7a, 7 of the pedestal 7
As shown in FIG. 4, a slight gap 12, 13 is provided between the two parts and b.

The lower corner of the outer surface 9a of the solution tank 9 is connected to the pedestal 7.
It abuts against a contact member 14 fixed to the lower end of the inner surface of the inner outer plate 7a. The other solution tanks 8 are also similar.

The solution tanks 8 and 9 contain different solutions such as detergent and wax, respectively.

As shown in FIGS. 2 to 4, a channel material 10 that opens upward and faces left and right is fixed between the solution tanks 8 and 9, and a vertical holding plate is attached to the bottom plate 10a of the channel material 10. The lower end of 15 is fixed. A proximity switch 16 facing left and right is attached to the upper end of this holding plate 15, and its detection surface 1
6a faces inward, that is, to the right.

The lower ends of a pair of front and rear plate-shaped supports 18, 18 are fixed to a front-shaped holding member 17 whose base is fixed to the inner plate 7b of the frame 7.

A base portion 19a, which is the right end of the detection member 19 facing in the left-right direction, is pivotally mounted in the middle of both the support columns 18, 18 with a horizontal shaft 21 facing in the front-rear direction.

As shown in FIG. 4, the detection member 19 is made of a substantially horizontal plate-shaped member, and the detection plate 19b, which is formed by bending its free end downward, is connected to the detection surface 16a of the proximity switch 16. It is located below.

As shown in FIG. 2, the lower parts of a pair of columns 22 and 23 are fixed to the bottom plate 10c of the channel material 10, and the upper ends of each column 23 and 23 are provided with a horizontal plate facing in the front and rear direction. The shaft 24 of is fixed.

This axis 24 is orthogonal to the detection member 19,
It is located below the middle of the detection member 19, and at the front and rear ends of the shaft 24, there are rotating members 25 and 25, respectively.
26 bases are pivoted.

The free ends of the pivoting members 25, 26 face inward, ie, to the right, and the lower ends of tension springs 27, 28, which face vertically, are engaged with the free ends.

The upper ends of the tension springs 27 and 28 are locked to each end of a shaft 29 fixed to the upper end of the column 18. Due to the force of the tension springs 27, 28, each of the rotating members 25, 26 is given a rotating behavior in which its free ends are raised, that is, in a counterclockwise direction in FIG. .

Operating members 31 and 32 facing in the front-rear direction are fixed to the middle of the rotating members 25 and 26, respectively. Proximal ends 31a, 3 of both actuating members 31, 32
2 a extends below the detection member 19 .

The other ends of the rotating members 31 and 32 are bent upward, as shown in FIG. 3, and then horizontally bent rearward and forward, respectively. Each horizontal bent part 31
b, 32b press the outer surfaces 9b, 8b of the solution tanks 9, 8, respectively.

The detection device 11 configured as described above is
It is covered by a cover 33, the lower part of which engages with the channel material 10.

Hoses 34a and 34b for taking out the solution to the outside are attached to the upper parts of the solution tanks 8 and 9, respectively.

When the solution tanks 8 and 9 contain enough cleaning solution, the actuating members 31 and 32
Despite the pressing action of the solution tank 8,
9's attitude remains unchanged.

When the solution in the solution tank 9 becomes less than a predetermined amount, the weight of the solution tank 9 decreases.
Due to the elasticity of the tension spring 27, the rotating member 25
rotates in such a direction that its free inner end rises.

At the time of this rotation, the actuating member 31 rotates in the same direction, and its horizontal bent portion 32b pushes the rear surface 9b of the solution tank 9, so that the solution tank 9 is tilted to the detection position 9A.

When the actuating member 31 is moved from the set position shown in FIG.
When pivoted to the operating position shown in FIG. 5, the end 31a of the operating member 31 pushes around the lower surface of the sensing member 19.

When the detection member 19 rotates to the operating position shown in FIG.
The proximity switch 16 is operated.

By operating this proximity switch 16, the washer 1
A warning indicator 35 consisting of a buzzer or a lamp provided in the solution tank 9 is energized to indicate that the remaining amount of solution in the solution tank 9 has decreased below a certain level.

Replenishment of new solution to the cleaning machine 1 can be performed by replacing the empty solution tank 9 with a spare solution tank (not shown) filled with solution by simply attaching and detaching the hose 34b. I can do it. Therefore, replacing the solution tank 9 requires the detection device 1
Since step 1 can be done without any special operations, the work efficiency of car washing is improved.

The remaining amount of solution in the other solution tank 8 is determined by rotating the operating member 32 to the operating position in the same manner as described above, so a description thereof will be omitted.

When the remaining amounts in both solution tanks 8 and 9 simultaneously fall below a certain amount, both actuating members 31 and 32
is activated, the detection member 19 is rotated to the detection position, and the remaining amount detection operation described above is performed.

When the remaining amount of solution in either of the solution tanks 8, 9 decreases below a predetermined value, the detection member 19 is rotated by the corresponding actuation member 31 or 32, so that one proximity switch 16 By using the detection member 19 in common, the amount of solution remaining in the solution tanks 8 and 9 can be detected separately.

In the above embodiment, a case has been described in which the solution tanks 8 and 9 are provided on the left leg 1b of the washing machine 1, but similar solution tanks 8 and 9 and a detection device are provided on the right leg 1c. 11, the remaining amount of the solution can be detected in the same manner as in the above embodiment.

[Effect of idea]

According to the present invention, one end of the pair of actuating members presses one side of the pair of solution tanks, and the other end of the actuating member is disposed facing near the bottom of one sensing member. As a result, when the remaining amount of solution in both solution tanks decreases below a certain amount, the remaining amount of solution in the solution tanks can be checked by tilting the solution tank, rotating the detection member, and activating the proximity switch. It can be detected and the solution tank can be easily replaced.

In addition, since the detection member can be rotated to the detection position and actuated the proximity switch by the independent operation of any of the actuation members, one detection member and the proximity switch can be used in common to accommodate different solutions. The amount of solution remaining in the pair of solution tanks can be detected separately.
