Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The invention relates to a drying device for drying motor vehicles in a portal vehicle washing installation, the device being arranged on a portal support and extending in the plane of the support. a horizontal blower casing, at least one blower connected to the blower casing, and controlled by a control device mounted movably in the height direction on the support and following the contour of the vehicle and having a downwardly directed outflow opening;
and a horizontal slotted nozzle communicating with the blower casing.

The drying device of the prior art portal washing installation has one usually two rigid lateral nozzles and a horizontal slot nozzle whose height is adjustable and controlled according to the contours of the vehicle to be dried. Slotted nozzles are used to dry upward surfaces of vehicles such as engine hoods, windshields, roof surfaces, tail nozzles, and luggage mantles. In order to use only a minimum amount of air and to reduce the level of power consumption, horizontal slot nozzles, also referred to as roof nozzles, are moved as closely as possible at small intervals along the surface of the vehicle. The nozzle is controlled by a light barrier that senses the contours of the vehicle or by a wheel connected to a slotted nozzle and rolling against the surface of the vehicle. Slotted dust nozzle.

It communicates by means of a hose or by means of an inlet/outlet pipe with a blower casing which is arranged rigidly in the upper transverse part of the portal support.

5 Problems to be Solved by the Invention The difference in height to the surface to be dried is relatively large, being 2.5 m from the aocML above the ground.

Flexible or retractable pipes must be relatively small. As a result, when a hose is used for 1%, the pressure loss is not small. Ingress and egress pipes are extremely expensive due to their construction, and they also do not move when you talk. Additionally, hoses and access pipes take up a lot of space. Vehicle washing and drying equipment is commonly used in small shops to wash and dry even the largest vehicles.
It is most important that all units be placed within a very small space.

The purpose of this invention is to provide a vehicle washing and drying equipment.

In particular, the purpose is to provide a gate-type washing equipment that has a simple structure, is small in size, has almost no failures, and consumes little energy.

According to the invention, the slotted nozzle is arranged directly below the blower casing, and the blower casing, together with the slotted nozzle and the blower, is attached to the support as one unit in the height direction. The above-mentioned problems are solved by equipment movably attached to.

The fact that the blower casing is movable in the height direction means that
This means that hoses and access pipes are unnecessary. This structure is a simple construction of a known drying device, but
Additionally, guide rails, a drive motor, and a control device are required to move the horizontal slot machine nozzle in the height direction.

Eliminating hoses and ingress/egress pipes means that one source of problems can also be eliminated. At the same time, the overall structure becomes more compact, especially in the height direction, because in known drying installations, the inlet and outlet pipes, in their stowed or retracted state, are connected to the slotted nozzle and the blower casing. This is because some minimum distance between the two is always required. The elimination of inlet/outlet pipes, but in particular the elimination of hoses, means that the pressure loss between the blower and the nozzle is reduced to a minimum so that the blower can be used with low output power, thereby saving energy.

In one preferred embodiment of the invention, the blower is disposed at both ends of the blower casing.

The blower supplies air to half of the slotted nozzle.

as it flows from the blower to the outlet opening of the slotted nozzle.
The distance that air has to cover is reduced to a minimum.

In another preferred embodiment of the invention, the support has a box-shaped, hollow, downwardly opening lateral part with a cross-section larger than the cross-section of the blower casing, and the blower casing is inserted into the lateral part from below. You can move completely up to This structure is.

Can reduce the amount of space required for drying equipment.

This is because the blower casing is no longer attached to the transverse part, as in the conventional type, but is drawn into the transverse part.

Furthermore, in particular in the case of portal washing installations, it offers the advantage that the drying device does not have any adverse effects, whether mechanical or visual, when other functions are carried out, for example during the washing operation. .

When the blower casing containing the slotted nozzle is drawn into the lateral section, no spray accumulates in this nozzle during the cleaning operation. Such water escapes from the nozzle during the drying process, thereby adversely affecting the drying process.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

The illustrated portal support 1 is reciprocated in the direction indicated by arrow B relative to a stationary vehicle. A blower casing 2 is arranged on the support l in a direction transverse to the direction of movement B of the support l.

Each blower 3 is disposed at each end of the blower casing 20, and these blowers draw in drying air from the surrounding atmosphere.

The blower casing 2 is divided into two by a central partition wall 4. Slotted nozzle 5 with a downward outlet opening 5a
is arranged directly below the blower casing 2. As can be seen in FIG. 2, the slotted castle nozzle 5 substantially forms the bottom part of the blower casing 2.

The blower casing 2, the blower 3 and the horizontal nozzle 5 are
A unit is formed which is attached to a support l so as to be movable in the height direction indicated by (2). For this purpose, the blower casing 2 is connected to two transverse guide rollers 6 which are guided on guide rails 7 connected to the upright member 1a. The blower casing 2 is suspended on two flexible traction members 8, such as toothed belts or deens. At the other end of the traction member 8, a counterbalance 19 is arranged. The flexible traction member 8 is attached to two toothed wheels or toothed sleds 10 with the toothed wheels arranged on a common horizontal drive shaft 11 .

The drive shaft 11 is described in German published patent application (DE-O8) No. 2.
It is driven by the control motor 12 via the intermediate freewheel 13 in a manner similar to that described in No. 518,718. The control motor 12 and the freewheel 13 are configured to drive the two flexible traction members 8 only in such a way that they lift the blower casing 2 .

In this regard, motor 12 is controlled by a light barrier or similar non-contact sensing device. 1 proof of blower casing 2 including related connecting parts is balanced! It is not completely compensated by the weight 9, which is configured to be slightly more convoluted than the balanced weight. Due to this slightly greater weight and the freewheel 13, the blower casing 2 with the nozzle 5 can be lowered.

Generally, the control motor is constantly driven in a first rotational direction that drives the drive shaft in the S direction. but.

Since the freewheel 13 rotates freely in its direction of rotation, no driving coupling occurs between the motor 12 and the drive shaft 11, and the blower casing 2 is blocked by the light beam of the light barrier 14 by the surface of the vehicle to be dried. until it is moved downwards by the effect of that slight excess weight. Thereby, the control motor 12 is switched to the second rotation direction in which the freewheel 13 is in a fixed state. the result,
The drive shaft 11 is driven in the h direction.

Accordingly, the blower casing 2 and the nozzle/I 15 are raised until the light barrier 14 is above the vehicle surface, so that the light beam is no longer blocked. When the receiver of the light barrier 14 receives the light beam again, the direction of rotation of the control motor 12 is reversed again and rotates in the first direction of rotation, so that no further upward movement occurs. In this way, the nozzle 5 is constantly moved along the vehicle surface to a close position above the vehicle surface. As shown in FIG. 2, two light barriers 14 are preferably placed on either side of the nozzle 5 and somewhat below the nozzle. In the event of a failure of the light barrier control device, two safety devices, such as a pressure wave switch 15, are arranged on either side of the nozzle 50 in close proximity to the outlet opening 5& of the nozzle 5, so that the light barrier As soon as 14 comes into contact with the vehicle, the portal drive is shut off.

The horizontal transverse portion 1b of the portal support l is box-shaped and hollow, and preferably has an opening 16 at its lower side. The cross-sectional size of this opening 16 and the transverse portion 1b is such that the blower casing 2, including the nozzle/L15, can be moved completely into the transverse portion 1b with respect to the blower casing 2 and its associated parts. It will be done. In this way, the blower casing 2 and the slotted nozzle 5
are protected from spray water during the cleaning process.
