Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surface treatment method for objects, particularly automobiles, such as those required when repairing a damaged car body or restoring the car body to good condition. and devices.

To repair a damaged automobile body, the metal shell of the body is hammered to the original body contour and substantially matches the original contour. After such hammering, the surface is filled with a hardened sealing material, sanded to obtain a smooth surface, then a primer is applied and finally two layers or
Further surface coatings are applied. The restoration work is
Heat treatment, for example, to dry the sealing material, or to dry or pre-cure the primer before applying the surface coating, or to dry one or more surface coatings. can be accelerated by

The present invention allows complete heat treatment of an automobile body within which operations can be carried out without transporting between different work stations for coarse polishing, priming, filling, fine polishing and surface coating of the vehicle body. The present invention provides a method and apparatus that allows both processes to be carried out within the same booth.

The invention is particularly suitable for the processing of motor vehicle bodies in processing booths which undergo the above-mentioned steps after the body has been worked into shape by striking or hammering.

Prior to the present invention, prior art techniques for finishing automobile bodies included the use of separate convection ovens or infrared ovens to accelerate the drying or curing of surface treatment materials. In such conventional operations, the temperature inside the furnace is maintained at a relatively low level to avoid overheating the heat-sensitive surface treatment materials, thus allowing the heat treatment to take place over a relatively long period of time. It was common practice to do so. This resulted in a distributed heat treatment and substantial time consumption at each stage of these operations. Additionally, transporting the vehicle body from one job to the next significantly increases processing time for all stages in the process.

In conventional convection ovens or infrared ovens, the heat treatment of the car body needs to be maintained at a low level for a period of 15 to 60 minutes to prevent overheating of heat-sensitive parts of the car body. It was said that In particular, vehicle roofs and vehicle hoods and trunk lids are relatively easy to heat and maintain at desired temperature levels; however, vehicle roofs and vehicle hoods and trunk lids contain numerous metal plates. Doors and other parts require substantially higher heat consumption than the aforementioned parts, and therefore the temperature rises more slowly.

The present invention is a method of surface treatment of automobiles and other objects that avoids the need to transport the vehicle body between successive work processes and allows the work and individual heat treatments to proceed continuously with minimal loss of energy and time. The present invention provides a method and apparatus for.

The invention also provides a processing or repair booth having a support on which a motor vehicle body can be placed for repair and restoration. The booth shall have suitable ventilation means to remove debris and vapors generated during repair and restoration operations. A heating trolley moves over the car body to supply heat to the car body and to heat the car body as required to accelerate the curing of different surface treatment materials used in repair work. Heat transfer is provided to apply the required amount of heat to the appropriate parts of the vehicle body without wasting heat in areas where it is not needed and as required by the particular task being performed. controlled, for example, by a calculator, in order to add without adding excess heat beyond that which is applied. The heating trolley is rapidly retracted after heat treatment, allowing other surface treatment operations to be carried out on the car body, application of surface coatings, and the like, without having to remove the car body from the booth. Subsequently, heat treatment can be performed.

The present invention includes a specially designed heating trolley which enables effective and efficient controlled transfer of heat radiation to the vehicle body, for example, and which also Appropriate ventilation means are included to remove solvent and other vapors and dirt particles from the vicinity of the vehicle body to prevent explosion, fire or contamination.

The heating trolley of the present invention utilizes thermal radiation to apply a desired level of thermal energy to the vehicle body. The heat radiating elements of the heating trolley are arranged in such a way that they direct the heat over the entire surface area of the vehicle body, e.g. under the control of a computer, so that only one heating trolley , any given selected part of the vehicle body can be programmed to be heat treated with the appropriate heat to accomplish a desired purpose.

The position and/or location of the heat radiating elements may be selected arbitrarily and may also be provided with reflective means to provide heat to the body parts that must be moderated from the direct heat radiation of these heat radiating elements. It is also possible to direct the radiation.

The support for the movable platform member 97 is such that when the movable platform member 97 is extended into the area behind the vehicle body B, the top surface of the movable platform member 97 is substantially flush with the work floor 7. It's summery. Thus, when extended as shown by the dashed line in FIG. Provides a convenient work area for performing any processing tasks. Lifting mechanism 9
The support platform 8 is raised and lowered to a convenient working height, but preferably the raising mechanism 9 is actuated by a remote control held by the operator. is desirable.

When repairing a damaged car body, after car body B has been hammered into the desired final shape, dents and other imperfections should be filled with, for example, two-component polyester, fillers or the like. Filled with suitable sealing material. This filler material is moldable and typically requires some predetermined curing time to cure and become suitable for sanding and subsequent painting. The curing time is
can be accelerated by adding heat,
According to the invention, heat is applied by controlled thermal radiation from a thermal radiation source. According to the invention, the irradiation of thermal radiation is limited to the specific areas requiring radiation, and other areas of the vehicle body do not receive any radiation, thereby preventing their Energy required to generate heat on other areas can be saved. For this purpose, the device according to the invention includes a heating trolley 19 which can be moved sufficiently over the length of the car body B inside the booth 1. , the heating trolley 19 also includes heat radiating elements, which are arranged in groups and optionally singly or
The heating trolleys are collectively energized and controlled to direct a desired degree of radiation toward the vehicle body B as the heating trolley moves along the length of the vehicle body B.

The heating trolley 19 and the thermal radiation source are designed and controlled such that the flow of energy to different parts of the vehicle body B results in a uniform final coating quality, regardless of where the damage is repaired. The heating trolley 19 includes a thermal radiation source 18 arranged in its interiorly directed wall (FIG. 8).
The thermal radiation source 18 consists of an infrared lamp in a suitable reflector and a heating trolley 19.
includes a duct that transports ventilation air from the ventilator inlet 20 to the thermal radiation source 18. Thermal radiation source 18
are arranged in horizontal and/or vertical clusters or columns, with one set of elements in each cluster. These thermal radiation sources 18 can be separately energized, either collectively or individually, as will be explained in more detail below. The heating trolley 19 is primarily designed to be substantially uniformly spaced from the outer circumference of the vehicle body B on the support platform 8.

The structure of the heating trolley 19 includes two side parts 22 and 23, as shown in FIG. low. It also includes two ceiling sections 24 and 25 arranged at obtuse angles to each other. Each ceiling section 24, 25 has a width smaller than the maximum width of the vehicle. side part 2
2, 23 and the ceiling parts 24, 25 are interconnected by two sloping parts 26 and 27.

At the front and rear ends of each of these sections 22 to 27 there is a deflection plate 28, which serves as a heating trolley between each section 22 to 27 and the vehicle body B. 19 interior space 21
is pivotably mounted so as to be directed inward so as to cover approximately half the width of the The baffle plate 28 increases thermal efficiency by blocking radiant energy from radiating outward. The lower parts of the side parts 22 and 23 have pivotable extensions 22a and 23a, which are arranged so that the radiation source 1
8a allows it to be placed closer to the vehicle body B when it requires an extra amount of energy in the often heavier lower parts of the vehicle sides.

The heating trolley 19 is provided with a trolley device (partially designated 29) having wheels (not shown);
It rests on rails 29a in the roof of the surface treatment booth 1, making it possible to move the heating trolley 19 along the car body B placed on the support platform 8. The control unit 4 controls a motor arrangement 29b (FIGS. 5 and 6) which moves the heating trolley 19 from the parking position to a suitable working position on the vehicle body.
That is, to any one or more of the front, middle or rear parts, doors or any other part of the vehicle. Control unit 4
The heating trolley 1 is equipped with a thermal radiant source with a sufficient amount of heat.
9 to the right or left, or into the lower or upper part, so that the time interval and radiation intensity desired for the material used for surface treatment Be sure to give it heat treatment. Finally, the control unit 4 causes the heating trolley 19 to return to its parking position shown in FIG.

The heating trolley 19 moves along the motor vehicle at a certain speed determined by the control unit 4. For example, if you are trying to repair the door of car B, or any other large area,
The first radiant lamp 18 in the direction of movement is activated just before the heating trolley 19 reaches the door, and then the next lamp is activated in sequence as the heating trolley 19 moves along the vehicle. The radiant lamps are then extinguished in an orderly manner as they pass the surface area to be heated in the direction of movement. Returning the heating trolley 19 to its parking position can be done very quickly while deactivating the infrared lamps. It is also possible to energize and deenergize the lamps 18 in the reverse order to effect a return at a lower speed and obtain a second heat treatment.

The control unit 4 can also be programmed to treat small areas without movement of the heating trolley 19. According to such programs,
The control unit 4 moves the heating trolleys 19 from their parking position to a predetermined position on the car, i.e. at the front or rear, at the door or at any other part, and deposits the required number of heating trolleys 19. energizing the thermal radiation source to the right, left, downwards or upwards as determined by the required time interval and radiation intensity on the material being used for surface treatment, and finally , the heating trolley 19 is returned to the parking position.

The booth 1 and the heating trolley 19 are ventilated before, during and after the heat treatment process. Connect the air inlet 5 to the discharge side of the air blower, and connect the air inlet 5 to the discharge side of the air blower.
Advantageously, the air is circulated through the booth 1 by being connected to the suction side of a second blower. Adjustable warping plate 51
is placed under the inlet 5 to ensure the desired air distribution throughout the booth 1 and to limit the transmission of noise.

As shown in FIG. 2, the air inlet 5 directs pressurized air into the ceiling area of the booth 1, which is formed as a plenum 47 between the facing walls. The lower part of the filling chamber 47 is the booth 1
In order to prevent foreign matter from entering the working area of the machine, it is formed by a grid or grid window 48 with a suitable filter medium 49. The working floor 7 of the booth 1 likewise forms a grate working section 52, which allows air to be discharged downwardly through the working floor 7. A suitable filter medium 53 is placed below the work surface 7 to capture particulate matter and prevent it from interfering with the evacuation mechanism. As indicated by 52',
The grate work floor section 52 can also be removed to provide access to the filter media 53 for removal and replacement.

To replenish the flow from the air inlet 5 to the outlet 6, a replenishment conduit system 56 is provided outside the booth 1, preferably for introducing and discharging additional air for pollution control purposes. Vent holes 57 and 58
It is desirable to provide The vents 57 and 58 are
These windowed walls are installed in the central part of the windowed walls of Booth 1.
To enable necessary information to be exchanged between workers inside the booth 1 and people outside the booth 1. The blower flow supplying the air inlet 5 and exhausting the air outlet 6 and the flow through the replenishment system 56 exit through the grate window 48 and into the grate section 52 as necessary to provide a laminar air flow. level, thereby avoiding air turbulence that would adversely affect the treatment being carried out on the vehicle body B in the booth 1.

Ventilation air also flows through the heating trolley 19 to protect the infrared or other heating elements from paint solvent or solvent vapors that escape during drying or pre-curing. This creates a ventilated area to prevent direct contact between elements and solvent vapors that might otherwise cause a fire or explosion.
FIG. 8 shows a preferred embodiment in which a heating trolley 19 containing infrared radiators and/or heating elements and air nozzles is
It is adapted to be moved above the automobile by a drive motor 29b. Ventilation air is supplied from the open bottom of the plenum 47 through the filter 43 and enters the heating trolley 19 through the inlet 20. Air is supplied from nozzles or slots 17 along and between the infrared radiators and/or heating elements 18 and is discharged towards the vehicle body B in a laminar air flow indicated by arrows 45. A fan 4 is installed in the air supply path to the heating trolley 19.
6 are installed to promote laminar air flow between the reflectors 32 during operation.

When the heat treatment process is finished, the heating trolley 1
9 to the parking recess 39 and heating trolley 1
9 is ventilated by air from air inlet 5,
This air is under slightly overpressure with respect to booth 1. In this way, the ventilation air exits through specially designed slots either into the parking recess 39 or into the booth 1, but this ventilation air does not carry out the polishing or polishing in the booth 1. Particulate matter and solvent vapors are prevented from entering the heating trolley 19 when filling and spraying or final drying is performed. During such a process, a given air flow is supplied to the parking recess 39 and flows out through the gap surrounding the heating trolley 19;
Ensure that no evaporated solvent gets into this air. The end wall of the booth 1 closely surrounds the parking recess 39 on both its inner and outer surfaces, thereby keeping the reflector within the booth 1 when in the parking position. It is known to avoid exposure to the workspace. Appropriate equipment, eg rocker, eg tool cabinet. Install into this end wall.

As shown in FIG. 2, the heating trolley 19 is
When placed in the parking recess 39, the filling chamber 4
The ventilation air from 7 is also supplied to a channel 20 in the heating trolley 19. This air ensures that the air flows outwardly from the heating trolley 19 so that particulate matter and solvent vapors cannot enter the heating trolley 19 during polishing, filling or paint spraying. Make sure not to. Ventilation air from the heating trolley 19 is also channeled through a specially designed slot from the parking recess 39;
It is ensured that no particulate matter, paint, solvent or solvent vapor can reach the heating trolley 19 during polishing, filling or paint spraying. In this way, the otherwise possible risk of explosion when energizing the infrared radiator or heating element can be avoided.

The control unit 4 adjusts the counterplate 51 for starting and terminating the operation of the ventilation system and for energizing the thermal radiation sources inside the different parts of the tunnel-shaped heating trolley and for controlling the thermal radiation sources. A preset program is established to control the intensity and time interval to a level between the maximum and minimum temperatures allowed for the duration of the heat treatment. manual override of the program,
It is included in the control unit 4.

Figure 15 shows these levels for accelerated curing on paint on an automobile body.
FIG. In the figure, the horizontal axis represents the heat treatment time t, and the vertical axis represents the vehicle body temperature T. curve 110
indicates the highest possible temperature without curing occurring with the risk of foaming or pinholes. The lower curve 111 represents the lowest temperature required to provide the least amount of heat to cure the paint.

According to the invention, the relationship between time and temperature is 11
2, which means that the treatment can be carried out at a correspondingly high temperature and within a relatively short time. Curve 113 represents a conventional infrared drying process and curve 114 represents a conventional oven drying process.

It is clear that the time consumption in the case of both curves 113, 114 is high, and that even if the temperature is kept at a moderate level, the overall heat demand is high;
This is already well known. Since each repair operation requires several successive process steps with drying cycles, the entire repair is time consuming and therefore expensive. As a comparison, it can be said that the conventional drying time is 15-60 minutes. According to the invention, it is possible to obtain the same result within a heat treatment cycle of less than 4 minutes, however, typically 1-2 minutes.
In repair work, it is not necessary to completely dry or bake the retouched paint, but to force the drying process by rapid evaporation of the solvent and subsequent processing. It is necessary to start hot air drying so that the Furthermore, the remaining heat diffusion allows the heat to penetrate into the hidden areas of the vehicle body and its frame so that the complete heat treatment as required occurs.

When working in a higher temperature range according to curve 112, different surfaces are heated evenly during the short available time intervals, independent of their position with respect to heating trolley 19. However, it is necessary to place the heat source as soon as possible.

As mentioned above, the greatest difficulty arises when initially trying to achieve a uniform temperature distribution.
This is the relationship between the roof of the car, the hood, and the ceiling of booth 1. One correct design that is envisioned to be suitable for automotive processing is shown in FIG. The hood 15 on car B is of conventional type and is placed at a lower level than the roof of the car. The same applies to the trunk lid. It is therefore desirable to design the construction of the heating trolley 19 in such a way that the beam of energy at the body surface to different parts of the body B is approximately the same. The two separate parts 26 and 27 are positioned and dimensioned such that each of them can illuminate at least half the width of the hood 15. Despite its rather low position below the ceiling parts 24 and 25, the hood 15 provides sufficient illumination from the two ceiling parts 24 and 25 and the separate parts 26 and 27.

Since the task of remanufacturing an entire automobile body is rare, the radiation sources 18, 18a and the different parts 22~
27 is connected to the program control unit 4;
This control unit 4 controls the radiation source for a given task. Extensions 22a and 23a
Regarding, as mentioned above, it may be necessary to arrange different radiation intensities in different parts. For example, an acoustically absorbing pad on the inside of a door may require additional heat to be drawn from the side portions 22, 23 compared to the heat from the ceiling portions 24 and 25. The time and radiation intensity are related to the material used for surface treatment. The reflector is designed to spread the emitted radiation over a given array. For example, the reflector may be oval, parabolic, or shaped to provide the desired spread of energy.
It is fine if it is constructed by another engineer.

FIG. 10 is a cross-sectional view of a side portion of a wall 30 of a motor vehicle containing a door 31. FIG. Four infrared radiation sources 18 are mounted in a reflector 32 designed to provide a certain spread of radiation, for example an oval spread. In treating the car wall 30, the heating trolley 19 moves along the car at a speed determined by the control unit 4. After the door 31 has been repaired and painted, the heating trolley 19 connects the first infrared radiation source 18 to the door 31.
The heating trolley 19 is energized immediately before the heating trolley 19 passes, and the next radiant source is energized in order as the heating trolley 19 passes. The radiation sources are then de-energized in the reverse order as they pass the opposite edge of door 31. The end portion of the heating trolley 19 is indicated by the dotted line 33
It is shown by.

Reflector means are provided at each end of the platform 8 to facilitate heat treatment of the lower parts of the front and back of the vehicle body B. At the front end there is a flat reflector 6 made, for example, from an aluminum plate.
1 is stored in a vertical slot 62 in the work floor 7 immediately in front of the support platform 8 (7th
figure). The reflector 61 has a suitable handle (not shown) to enable it to be lifted out of its housing 62 into the phantom position, which is inclined at approximately 30 degrees. If the support platform 8 is placed at the level of the work floor 7, as is the case during heat treatment, the reflector 61 directs the radiant energy directed towards the front part of the car body B to the lower part of the front part of the car body B. It is effective for reflecting the light back to the target.
During hammering and spraying operations, the reflector 61
is re-enclosed within its housing 62 and suitable sealing means are provided to keep out particulate matter and vapors from the reflector 61 within the housing 62.

At the rear of the support platform 8, a similar reflector 64 is mounted above the workpiece entrance door 3. In the present case a separate reflector element 64 is mounted above each door 3. As shown in FIGS. 4 and 7, a reflector 64 is pivotally connected to the door 3 at one end and the reflector 64 is mounted at the other end.
It is supported by a post 65 which is pivotally attached to the top of 4. The strut 65 can be folded in such a way that the reflector 64 faces the door 3, as shown by the double-dashed line, and the channel 66 (FIG. 4) can be folded up to move the reflector 64 above the door. Provisions are made to hold it in its folded position. When open, the bottom edge of the reflector 64 is supported on a carriage member 97 adjacent the rear end of the support platform 8, as shown by the solid lines in FIG. The reflector 64 is the reflector 61
Similarly, it serves to reflect radiant energy directed rearward beyond the end of the vehicle body B toward the rear lower portion of the vehicle body B.

The modification of the heating trolley is shown in the 12th, 13th and 1st
It is shown in Figure 4. In this embodiment, heating trolley sections 122-127 are similar to sections 22-27 described above with respect to FIG.
However, in this embodiment, the portion 123
and 123a are mounted for pivoting movement relative to portion 127 about a vertical axis, and
Portions 122 and 122a are pivotally mounted above portion 126. As shown in Figure 12, the lower part can also be rotated so as to provide direct radiation onto the front and rear parts of body B as the heating trolley moves over the body. . The pivoting movement of the lower part of the heating trolley is controlled by a conventional servo mechanism from the control unit 4 such that when the heating trolley advances towards the support platform 8, the lower part is directed towards the front of the vehicle body B. Then, when the heating trolley passes over the car body B, it is turned parallel to the car body B, and finally, when the heating trolley passes over the car body, it is turned towards the rear of the car body B. , may be controlled. As shown in FIGS. 13 and 14, the pivotable connection between the lower and upper portions is provided by bearings 130, which
It has an opening 131 to allow passage of air and passage of a conductor 132 between the two parts. This conductor 132
is for controlling the firing sequence and intensity of the infrared radiators, as described above with respect to the heating trolley 19, and is also provided with an air passage 131, which allows the reflection in the lower section to be controlled. It is designed to allow ventilation around the container. This is similar to the ventilation device provided around the reflector in the heating trolley 19 described above.

The program for the control unit 4 is preferably such that an operator can select one part of any one type and any type of paint out of a number of sets of a given car type, for example 99 sets. The design is preferably such that a selection can be made so that the program control unit 4 acts as a controller to suitably process the selected type of vehicle body. Similarly, individual controls may be provided to select specific parts of the car body that require repair, allowing the operator to simply select the desired part of the car body that is being repaired. The control unit 4 also limits the processing to that particular part of the vehicle body, so as not to waste energy treating undamaged parts of the vehicle body. Suitable interconnection means are provided to prevent infrared radiation from reaching persons and to ensure accurate advancement of the heating trolley when the heating trolley is actuated to begin its movement over the vehicle body. controls and ensures that the selected operation of the infrared radiators is effective for treating the desired portion of the motor vehicle body placed on the support platform 8. Suitable guiding means (not shown) ensure that the vehicle is properly placed on the platform 8, and pollution sensors ensure that vapors from solvents and other process materials energize the radiator. Make sure to completely drain the booth beforehand.

The illustrated embodiment shows only one booth with a parking area for a heating trolley at one end. The same heating trolley is used for two or more booths, and they extend from one end to the other with a parking recess for the heating trolley in the space between the two or more booths. It is clear that it is okay to leave it up to that point. In this way, while the heating trolley is being used to heat treat the car body in one booth, other operations can be carried out on the car body in the other booth, and vice versa. It can also be done.
By suitable modification, the same heating trolley can be transformed into two
It can also be operated to handle more than one booth.

While particular embodiments of the invention have been illustrated and described, it is not intended that the invention be limited to such embodiments, and many variations and modifications may be made without departing from the spirit of the invention. It should be understood that there are things that can be done to this embodiment without going away.
