Description

Safety side blowing equipment of car washing machine

The new model relates to a blowing device, in particular to a side blowing device for a car washing machine.

Car washing machines at gas stations are currently quite common car washing machines, one of which is a reciprocating type in which car washing equipment reciprocates to clean parked vehicles. When the reciprocating type car washing equipment is used, since driving only needs to stop the vehicle at a predetermined position, there is no concern about whether the vehicle is aligned with the track of the rail-type car washing equipment, so it is more favored by consumers.

However, when this type of reciprocating car washing equipment is used, sometimes the rear mirror of the vehicle will be damaged. Investigation of the cause found that although the left and right blowing mechanisms of the reciprocating car washing equipment are equipped with sensors, they can be used for sensing. The distance between the side blowing mechanism and the side of the car is controlled, but because optical sensors are usually used, and the water attached to the surface of the vehicle sometimes affects the results of the optical sensing, and the rear mirror is a protruding part of the side of the car. Small pieces of components are likely to cause missing sensing, and the side blowing mechanism is not controlled to move sideways during the forward and backward movement to avoid the rear mirror, which may damage the rear mirror.

Therefore, the object of the present invention is to provide a safe side blowing device for a car washing machine that can improve at least one of the disadvantages of the prior art.

Therefore, the safety side blowing device of the new car washing machine is suitable for blowing air to the side of a vehicle, and includes a trolley mechanism that can be controlled to move forward relative to the vehicle, and a trolley mechanism that can be interlocked and displaced. Side blowing mechanism, an ultrasonic sensing device installed on the side blowing mechanism to be linked displacement, and a control device. The side blowing mechanism can be controlled to move left and right relative to the trolley mechanism, so that a tuyere used for laterally blowing gas is moved left and right relative to the vehicle. The ultrasonic sensing device will correspondingly generate a sensing signal when the vehicle is sensed on the forward path of the tuyere. The control device is signally connected to the ultrasonic sensing device, the trolley mechanism and the side blowing mechanism, and will start a blowing program to control the trolley mechanism to drive the side blowing mechanism to move forward, and can be triggered and controlled by the sensing signal When the side blowing mechanism moves sideways until the sensing signal is not received, the trolley mechanism is controlled to continue to drive the side blowing mechanism forward.

The effect of the present invention is that by using the ultrasonic sensing device to sense the front of the tuyere moving path, the reflection of the ultrasonic signal is not affected by water and liquid on the vehicle surface, and the ultrasonic signal can be sensed more accurately. When the vehicle is sensed and the mirror is looking after the vehicle, the side shifting device is controlled to shift the wind nozzle laterally to avoid the rear mirror, thereby improving the safety of the car washing machine.

The side shift rail 32 has two rails 321 extending left and right and spaced in parallel up and down, and a rack 322 extending left and right and located on opposite sides of the rails 321.

The side blowing mechanism 4 includes a side shifting device 41 installed on the side shifting rail 32 and protruding out of the trolley body 31 capable of lateral displacement, and a tuyere 42 installed on the side shifting device 41. The side shifting device 41 includes a movable wheel frame 411 that can be displaced to the left and right and clamped against the rails 321 upward and downward, and a driver 412 installed on the movable wheel frame 411 and engaged with the rack 322. The driver 412 can be driven to rotate left and right along the meshed racks 322, thereby driving the movable wheel frame 411 to move left and right along the rails 321. The tuyere 42 is installed on the movable wheel frame 411 so that it can be moved left and right, and is exposed on the side of the body 31 of the trolley. It will be connected to a high-pressure air source (not shown) and has a vertical extension The air outlet 420 is used to spray the received high-pressure gas toward the side of the vehicle 900.

The safety protection devices 6 are installed on the tuyere 42 with left and right intervals, and can be moved left and right by the tuyere 42. The safety protection devices 6 are far away from the side shift device 41 relative to the air nozzle 42 and relatively adjacent to the side of the vehicle 900. Two of them are located at the front and rear sides of the air nozzle 42 respectively, and the other is located corresponding to the air nozzle. The outside of the air outlet 420 of the mouth 42. Each safety protection device 6 includes a light emitter 61 and a light sensor 62 that are installed at the top and bottom ends of the tuyere 42 at an upper and lower interval, and the light emitter 61 can emit a light toward the light sensor 62. Detecting light, the light sensor 62 can sense the detecting light and correspondingly generate a detection signal.

The ultrasonic sensing device 5 is installed on the tuyere 42 so as to be able to move left and right, and is relatively located in front of the moving path of the tuyere 42 and is also close to the side of the vehicle 900 relative to the safety protection devices 6. The ultrasonic sensing device 5 sends an ultrasonic signal downward to sense the vehicle 900, and when the received ultrasonic reflection signal is analyzed to determine that the vehicle 900 is sensed, a corresponding sensing signal is generated.

The control device 7 is signally connected to the trolley mechanism 3, the side blowing mechanism 4, the ultrasonic sensing device 5, and the safety protection devices 6, and the blowing program is built in. When the blowing program is started, Control and activate the sensing functions of the ultrasonic sensing device 5 and the safety protection devices 6, and correspondingly control the trolley body 31 according to the sensing results to drive the side blowing mechanism 4 to move forward and position relative to the vehicle 900, and control the side The side shifting device 41 of the blowing mechanism 4 is positioned left and right relative to the trolley mechanism 3, and then the water and liquid blowing operation is performed from the front to the rear of the vehicle 900. Since the control device 7 controls the forward positioning of the trolley body 31, and controls the lateral displacement and positioning of the side shift device 41 along the side shift rail 32, and they are not the focus of the improvement of the present invention, they will not be described in detail.

The following is a description of the operating mechanism of the control device 7 when the safety side blowing device 200 of the present invention is used to blow off the side water of a vehicle 900 parked in a car wash position.

Referring to Figures 2, 4, and 5, the blowing procedure has a first blowing stage and a second blowing stage that will be executed in sequence. When the control device 7 executes the first blowing stage, it controls the trolley body 31 to move forward relative to the vehicle 900 from the blowing start position, so that the side blowing mechanism 4 drives the ultrasonic sensing device 5 and the safety protections The device 6 advances synchronously, and controls the activation of the ultrasonic sensing device 5 and the safety protection devices 6, the ultrasonic sensing device 5 will start to sense the vehicle 900 downward, and the light emission of each safety protection device 6 The sensor 61 and the light sensor 62 also start to detect whether there is an object between them.

When the control device 7 receives the sensing signal, it means that the ultrasonic sensing device 5 has sensed the front side area of the vehicle body 901, and the control device 7 will control the trolley body 31 to stop moving forward and control the side The moving device 41 moves a predetermined distance away from the vehicle body 901 along the side moving rail 32, so that the ultrasonic sensing device 5 moves sideways to no longer sense during the remaining stroke of the first blowing stage. When it is within a safe distance range from the side of the vehicle body 901, at this time, the tuyere 42 will be driven to move sideways to maintain a predetermined distance range from the side of the vehicle body 901. Then, the trolley body 31 is controlled to continue to move forward, so that the tuyere 42 blows the water on the side of the body 901 toward the rear of the vehicle.

Referring to FIG. 6, when the control device 7 receives the sensing signal again, it means that the ultrasonic sensing device 5 has advanced to above the rear mirror 902 of the vehicle 900, and the vehicle 900 is sensed again, and It means that the rear mirror 902 will be located on the forward path of the tuyere 42, and at this time, the control device 7 will continue to enter the second blowing stage of the blowing procedure.

Referring to Figures 7, 8, and 9, the control device 7 will control the trolley body 31 to stop moving forward, and control the side shifting device 41 to drive the ultrasonic sensing device 5 to move sideways away from the vehicle 900 until no more sensing is received. Detecting the signal, at this time, the air nozzle 42 is also synchronously driven by the side shift device 41 to move sideways away from the vehicle 900, and the forward path of the air nozzle 42 is adjusted to deviate from the rear mirror 902. Then, the control device 7 will control the trolley body 31 to continue to advance, and advance the trolley body 31 for a predetermined distance so that the tuyere 42 is driven to advance through the rear mirror 902, and then moves away from the trolley body 31 according to the previous time. The side shift distance of the vehicle 900 is controlled to drive the side shift device 41 to drive the tuyere 42 to side shift corresponding to the side shift distance to approach the vehicle 900, and then the trolley body 31 is controlled to move forward.

Immediately afterwards, the control device 7 will control the side shifting device 41 to drive the ultrasonic sensing device 5 to move left and right once every time it advances a predetermined distance, for example every 3 cm, during the process of controlling the trolley body 31 to move forward. , And by analyzing whether the ultrasonic sensing device 5 generates the sensing signal, the side shifting distance of the side shifting device 41 is slightly adjusted, so that the distance between the side shifting device 41 and the side of the vehicle body 901 is maintained at the ultra The sound wave sensing device 5 does not generate the shortest distance of the sensing signal, so that the tuyere 42 is kept at a predetermined distance from the side of the vehicle body 901 at any time during the advancing process, until the control of the The trolley body 31 advances to the blowing end position to complete the second blowing stage.

Through the control device 7 during the execution of the second blowing stage, the side shift device 41 is controlled to drive the ultrasonic sensor device 5 sets of left and right displacement detection body 901 every time the trolley body 31 advances a predetermined distance. The vehicle 900 is parked at the car washing position obliquely left and right, so that the air nozzle 42 can be kept at a predetermined distance from the side of the body 901 at any time with the best water blowing effect.

In addition, when the trolley body 31 drives the side blowing mechanism 4 forward, each safety protection device 6 will continue to detect whether there is a foreign object through its light emitter 61 and light sensor 62. Once it is detected When a foreign object causes the detection signal to be interrupted, it means that a foreign object is too close to the tuyere 42, or is located in the path before the tuyere 42, the control device 7 will immediately control the trolley body 31 to stop moving forward to avoid the tuyere 42 Hit the foreign body.

With the detection function of the safety protection devices 6, it can be used to assist in detecting whether there are foreign objects before and after the moving path of the air nozzle 42 and at the air outlet 420, such as the presence of the rear mirror 902 of the vehicle 900, people or animals If one of the safety protection devices 6 detects a foreign object, the control device 7 will immediately stop the trolley body 31 from moving forward to prevent the tuyere 42 from colliding with the foreign object. The staff can perform equipment inspection immediately, and can cooperate with the ultrasonic sensing device 5 to reduce the probability of the tuyere 42 colliding with the vehicle 900 or foreign objects, and relatively improve the safety of the entire car washing machine.

In summary, by installing the ultrasonic sensing device 5 on the side blowing mechanism 4, and enabling the ultrasonic sensing device 5 to sense the front of the moving path of the tuyere 42, the ultrasonic signal can be used The reflection is not affected by the water and liquid on the surface of the vehicle body, and can more accurately sense the vehicle 900. It can be used to accurately sense whether the rear mirror 902 of the vehicle 900 appears in front of the moving path of the nozzle 42, and the When the vehicle 900 is looking at the mirror 902 from the rear, the side-shifting device 41 is controlled to shift the air nozzle 42 laterally in time, and after the air nozzle 42 is driven to move forward through the rear mirror 902, the air nozzle 42 is controlled to approach the The body 901 of the vehicle 900, and by controlling the side shift device 41 in the second blowing stage to drive the ultrasonic sensing device 5 to move left and right relative to the body 901, so that the distance between the side shift device 41 and the side of the body 901 is maintained The shortest distance where the ultrasonic sensing device 5 does not generate the sensing signal, so that the tuyere 42 is kept at a predetermined distance from the side of the vehicle body 901 at any time during the advancing process with the best water and liquid blowing effect. In addition to avoiding the mirror 902 after the tuyere 42 collides with the vehicle 900 during the blowing process, it can further improve the water and liquid blowing effect. It can further cooperate with the design of these safety protection devices 6 to improve the safety of the entire safety side blowing device 200. Therefore, the present invention is indeed an innovative design of the safe side blowing device 200 with a relatively high level of safety, and it can indeed achieve the purpose of a new type of cost.
