DE2136335B2 - METHOD AND ARRANGEMENT FOR CONTROLLING THE PORTAL MOVEMENT OF A CAR WASH - Google Patents

Description

be guided along the vehicle during the movement of the portal. Have these brushes on At the end of the portal's travel path, when a certain position is reached, this may be used as a display for this apply that the portal has covered the distance necessary to cover the entire length of the vehicle Has. This fact makes it possible to obtain a signal related to the corresponding position of the brushes to be used for reversing the portal movement. The method used is based on the present Embodiment in the storage and evaluation of this signal for the second work pass of the portal, without being restricted to this assignment, as it is known to the skilled person of the invention is readily possible to evaluate it for other passes.

In the illustrated scheme of the portal control device, the individual elements have the following Functions:

61 switches

62 switches

63 switches

64 changeover switches

Wash the drive motor forward. Wash the drive motor backwards. Dry the drive motor
Dry the drive motor

Cl forward contactor travel motor with contact ei
CI reverse contactor travel motor

The switches bl to 63 are operated one after the other by hand or automatically by devices not shown in the following order:

61 caused at the beginning of the washing process
the 1st outward run,

bl during the washing process initiates the 1st return when bl is opened at the same time,

Z) 3 at the beginning of the drying process causes the 2nd outward flow and the 2nd return flow when bl is opened at the same time.

In the idle state, all switches are in the state shown; the contactors Cl and Cl as well as the motor m and the drive motor (not shown) controlled by the contactors Cl and Cl are de-energized.

If the switch bl is now closed by hand at the beginning of the washing process, the contactor Cl is energized. This switches the traction motor on for forward travel and in parallel with its contact el the motor m of the measuring device, which is always driven by this motor as long as the contactor Cl is energized and thus the traction motor is switched on for forward travel. The measuring device is therefore rotated by an amount which is proportional to the travel path of the washing portal. If the forward travel is interrupted for any reason, which is particularly important for intermittent operation, the distance measurement is therefore also interrupted to the same extent, but when the forward travel is continued, it is then continued in the same ratio. The rotation of the measuring device designed as a cam disk thus represents an image of the path of the portal covered during the first outward journey.

When the portal has reached the end of the vehicle. If the first outward run is interrupted by opening the switch bl , although the contact 64 reversed by the cam k of the measuring device at the beginning of the first outward run is now parallel to the switch b 1 , the contactor C1 drops out because the right contact of the switch 63 is open. The contact el opens and switches off the motor m of the measuring device; the measuring device remains in the assumed position, the measurement result is thus stored. To continue the washing process, the switch bl is now closed and the contactor Cl energized, which switches on the drive motor to reverse. At the end of this first return trip, switch b 1 is opened and the portal is stopped.

The subsequent drying process now takes place automatically so that the portal covers the same distance as was determined during the washing process in the first outward run. To initiate the drying process, the switch 63 is closed, which with its right contact switches on the contactor Cl and thus the drive motor for forward travel. At the same time it switches with his left contact the Ml or a m of the measuring device, which, however, was led in the opposite direction as the first trace during the washing process, and thus the cam rotates back in the initial position ih ^r e. When the cam disk has reached its initial position, the portal is in the same position as at the end of the first outward run, i.e. at the end of the vehicle to be dried. When the cam disc reaches the initial position, the cam k dtn switches switch 64 into the position shown, and thus the contactor Cl is switched off, forward travel is interrupted, but at the same time reverse travel is initiated by switching on the contactor Cl , which occurs at the end of the second reverse travel (not shown) Way is stopped.

The circuit diagram shown is only intended to illustrate the sequence of the individual processes. As is easy to see, the individual switching processes must be controlled in a specific relationship to one another. Thus, for example, it must be prevented that the contact el can switch on the motor m of the measuring device during the second outward run, since this is switched on rotating in the opposite direction via the left contact of the switch 63. Furthermore, care must be taken to ensure that several of the switches 61 to 63 cannot be actuated at the same time or that being actuated at the same time cannot cause damage.

In the course of the automation of the sequence of movements, in particular switching off the switch 61 and turning on the switch 6 2 through a device can be made to sense the far end of the vehicle to be washed, for which it is possible to train the washing brush as a tactile organ that controls the switching functions assumes that, for example, the first outward run will be maintained by her until she has passed the Vehicle has got out, but then automatically initiates and maintains the first return. The use the washing brush with regard to these individual functions is at the discretion of the person skilled in the art and is not the subject of the invention. Their use as a scanning organ to measure the length of the path The first outward run, on the other hand, represents an advantageous development of the invention.

The invention is also not based on the method of distance measurement and storage by means of the described method Cam limited; are also conceivable

Solutions by means of time relays, operating time counters or traction motors or the like. The invention thus includes in general the measurement, storage of the vehicle length once driven over and its reproduction in a later operation.

The invention is also not tied to drying the vehicle in a second run, but is very general for reproducing saved runs for further runs applicable regardless of the respective work process.
