Description

AID FOR MAINTAINING SUSPENSION OF COLOR PARTICLES IN CORRECTION STICKS

The invention relates to a preferably in assembly workshops o. The like. Production equipment usable auxiliary device, whereby a processing of paint jobs on products according to the preamble of claim 1 is feasible.

In assembly workshops of the automotive industry, the furniture industry, window construction or similar industrial plants, quality controls are carried out on the areas of products provided with paint jobs, so that repair and repair of, in particular, painting defects can be carried out in this production phase. Improvements in the area of installation-related transition zones, decorative defects, scratches or the like are preferably carried out in the field of industrial window construction. For this only manually executable activity is an application of appropriate paint-containing correction pencils usual, in particular paint pens are used with appropriate RAL color or wood decor paint.

To prepare one of these processing phases, the paint contained in the correction pens should be prepared in the form of a finely divided suspension in such a way that a sufficient paint quality is achieved. For this purpose, by a manual shaking of the worker, a corresponding amount of time must be planned to each, located in the correction pins mixing elements in the form of Stirring balls o. The like. To move. This creates a disadvantageous high expenditure for this correction work.

According to DE 29 42 994 C2 a stirrer is proposed, which is to be introduced into a paint container. In this paint container then the free mobility of this Aufrührorgans is secured, so that in a Aufschüttelvorgang a rotation of the paint is effected and this can be used after good mixing.

In a workshop trolley according to DE 202 15 706 U1, the construction is directed to the fact that optimal handling is possible for the work equipment of the painting trade to be deposited. A base plate located on a frame is designed so that both parts of the painter accessories and a flowable color material containing reservoir can be safely switched off.

In a device for ink supply to printing presses according to DE 10 2004 001 751 B4, respective ink cartridges are held in a revolving magazine. This concept is directed to the fact that by means of a transfer device respective empty cartridges can be replaced by full cartridges.

The invention is concerned with the problem of providing an auxiliary device for an assembly workshop which uses color correction products on correction products, so that a coating material prepared in the correction pen can be provided with the least possible effort as optimum suspension, while the preparation and times are shortened by the worker and an order of the correction coating with uniformly high quality is possible.

The invention solves this problem with an auxiliary device for an assembly workshop with the features of claim 1. Further advantageous embodiments of the auxiliary device will become apparent from the claims 2 to 26.

Starting from a so far in known production processes by the worker to be realized paint processing by a shaking by hand, the inventive concept is directed to an especially time-saving deployable auxiliary device in the form of a workshop car. This tool trolley, which can be used as a variably usable accessory, is provided with at least one pen magazine receiving the correction pens and drivable for mixing the paint contained therein. Thus, a construction is achieved in which the hitherto to be performed by the worker "shaking" of paints is now realized by a "machine".

In addition to the saving of preparation time that can be achieved with it, the respective production-specific changing correction coatings can be realized more quickly by the employee by means of a multiplicity of pencils prepared in parallel. In addition, a consistently high quality is achieved by the paint having an optimum suspension. The clear arrangement of several of the correction pins also containing different colors in an easy-to-survey pen magazine also allows a simplified material procurement. A dispatcher can easily detect respective "defects" in the pen magazine, so that a timely procurement of replenishment for the magazine is possible with optimal material utilization.

The realization of trained as a workshop trolley auxiliary device is directed to the fact that each, usable in variable size correction pins are ready to use available from their custody in the pen magazine at any time. The mixture of the respective paint is carried out by means of a variably executable movement initiation on the correction pen and / or directly on the pen magazine, so that the paint is placed in a bloated state and the respective correction pen can be used immediately after removal from its storage position for inking. The flexible design of structural parts for movement initiation provides that the correction pins held in the pen magazine can also be individually movably fixed.

One conceivable embodiment of the system provides that the mixing movement on the at least one correction pen held in the pen magazine can also be initiated by hand on a drive part. This movement initiation can then lead over a period of time to an "automatically" continuous movement of the correction pen. It is provided that by means of a hand movement a flywheel, a spring memory o. The like. Element are set in motion can, and after a - also adjustable - movement time then the correction pen can be used with mixed paint.

An optimal execution and completion of the workshop car provides that this is provided for a movement initiation in the pen magazine with at least one motor drive. This motor drive can be designed so that after the introduction of the movement, a continuous or phase-wise interrupted actuating force or acceleration acts on the correction pins and / or the pen magazine. This movement initiation in the area of a holder on the workshop trolley is directed to displacements of a respectively provided in the correction pen and here acting on the paint mixing element in the form of a ball or roller. This aiming at an optimal component mixture "shaking" can be adjusted in particular by respective performance parameters, adjustable speed and / or variable acceleration movements in the field of the drive.

The adaptable to different workshop cars concept of driven pen magazine provides that at this particular more of the correction pins in a respective variably predetermined deposit position can be fixed. In this case, this pen magazine can in particular interact directly with the drive causing the mixing movement of the correction pins or their mixing elements.

An extension of the above-described concept of the workshop car provides that this can also be provided with several drivable pen magazines. These pen magazines can be moved either via a common drive, or each of the pen magazines is provided with a separate drive. Starting from known drive systems with translational or rotary deflection, it is provided that the pin magazine (s) can interact with a rotary drive and / or a linear drive in the region of a transmission.

The compact design of the workshop trolley adaptable to the requirements in the respective production site provides that in this case the pin magazine provided with the drive and a housing part associated therewith are designed as a self-sufficient structural unit which can be detached from the workshop trolley. This is conceivable, this unit - regardless of the remaining workshop car - to place stationary at a place of use.

In an optimal embodiment of this designed as a functional unit construction of the workshop car is provided that this is connected to a chassis constructed as a base. Thus, a "portable machine" is provided, which is mobile to varying locations. In an advantageous embodiment, the unit comprising the driven pen magazine can be fixed to the substructure via at least one plug connection. It is also conceivable to provide here a screwed connection structure or a one-piece design of components.

The optimization of the auxiliary device is aimed at ensuring that the pen magazine provided in the region of the upper structural unit of the workshop trolley rotates having driven and the correction pins at star-shaped aligned to the axis of rotation axis fixing holder with corresponding mating receptacles. In an expedient embodiment, this holder is designed in the form of a retaining disk. At this, the plug-in receptacle in the form of corresponding holding parts, plug openings o. The like. Profilings may be appropriate. These profilings are arranged substantially such that the correction pins are arranged as a star or radial projecting from the central axis of rotation structure. Thus, in the variably adjustable rotational movement of the pen magazine, a corresponding displacement of the mixing elements located in the correction pins can be initiated, and the "shaking process" is realized under the effect of gravity.

A further embodiment of the pen magazine provides that the holder can also be embodied in the form of a support rod on which - in the longitudinal direction of the axis of rotation - one behind the other, the respective plug-in receptacle can also be arranged star-shaped protruding. In this concept, the "support rod holder" is compared to the retaining plate variable expandable number of plug receptors conceivable. The bracket provided with the support can preferably be stored or driven on both sides.

Another concept of a "horizontal" pen magazine provides that at this for the correction pens respective, a horizontal mounting position predetermining plug receptacle are held. Starting from this non-use position, a reciprocating motion or a pendulum movement in the region of the magazine with the plurality of holders can then be initiated by means of an adapted drive. so that with the acceleration in the area of the internal mixing elements of the mixing process is performed. This design of the pen magazine is directed to a "rapid shaker", which can be used for short-term processing phases to be realized. For continuous operation, the design of the rotating magazine is better suited.

The design in the region of the housing structure forming the upper structural unit of the workshop car provides a substantially box-shaped closed contour. In the interior of which cooperating with the front holding disk or the support rod of the pen magazine drive can be supported, so that for this a largely concealed and work-safe installation position is reached.

In this case, the drive preferably as a drive member via a mounted drive shaft and a gearbox connected to the rotating holder of the pen magazine construction with three-phase motor. Assuming that with the comparatively low weight of the correction pins a correspondingly sized drive power can be used, the assembly in the region of the preferably provided rotatable retaining plate is largely variable.

In particular, the construction is designed so that in each case two to forty, preferably twenty holding stations can be placed with plug-in receptacles in the region of the rotatable retaining disk. It is conceivable to provide the respective holding stations with corresponding marking elements, so that a color-appropriate sorting tion of correction pins is reached. Likewise, an arrangement of the correction pens can be specified according to their filling level, so that the "new" correction pens are distinguishable from those already used. Thus, an application-appropriate removal with orderly emptying of the pins is achieved.

An extension of the above-described magazine system provides that the workshop car can be provided in the region of its base also with at least a second pen magazine. It is conceivable to use the above-described rotating system. A second design of this additional magazine can be designed as the above-described "horizontal" magazine. This optionally located in the region of the substructure or the upper unit second pin magazine is formed in the manner of at least one of the correction pins in the mixing position receiving "vibrating plate". Thus, at least two variable mixing zones with different movement discharges are available for processing the correction pens.

A further embodiment provides that the workshop trolley in the region of the upper structural unit and / or the substructure can be provided with at least one measuring device provided for filling level determination on the respective correction pins. It has been found that in particular a weighing device which can be used for level measurement can be integrated into the system of the workshop car so that a rapid determination of the respective filling state and a corresponding selection for the worker can be made on the weight of the individual correction pins. is. At the same time - with optimal use of the paint - a quick and targeted replacement of spent correction pens is achieved.

It is In particular, provision is made for correction work to be carried out by means of a lacquer or the like, premixed paint, and to use respective correction pencils 2 (FIG. 2) containing the paint prepared as a suspension.

The inventive concept of the auxiliary device provides that it is provided in the form of the workshop cart 1 with at least one correction pin 2 receiving and usable for mixing the paint contained in this pen magazine 3. With this workshop cart 1, the correction pins 2 can be provided in an appropriate manner starting from a respective storage position (FIG. 2) in the pen magazine 3. This readiness position is achieved by the fact that by means of a movement on the correction pen 2 and / or the pen magazine 3 movement (rotational movement according to arrow D, Fig. 2) located in the correction pins 2 coating material is aufschwemmbar and then applied by the user of the pin at the correction point can.

From the overall view of the workshop trolley 1 in Fig. 1 it is clear that in the region of the pen magazine 3 more of the correction pins 2 in a respective variably predetermined storage position S (Fig. 1) can be fixed. It is conceivable that held in the pen magazine 3 correction pins 2 can also be moved individually. In principle, it is conceivable that the rotation D acting as a mixing movement is also introduced by hand on the at least one correction pen 2 held in the pen magazine 3. The optimization of the system provides that a movement initiation D takes place in the region of the pen magazine 3 by means of at least one motor drive 4 (FIG. 5). For this control of the mixing movement is conceivable that at the movement initiation D a continuous or phased interrupting force or acceleration acts on the correction pins 2 and / or the pen magazine 3. In any case, the drive concept is directed to a displacement of a correction pin 2 provided here and acting on the paint mixing element 5 in the form of a roll, a ball o. The like. Component. In this case, an optimization is carried out to the effect that with little effort a direct initiation of the mixing movement in the area of the pen magazine 3 takes place.
