"Paint spraying machine ^i!

The utility model concerns a paint spraying machine where a carrier for paint sprayer tools is arranged above a conveyor belt so that it can be moved back and forth »

In such paint spraying machines consists in continuously moving band of ₅ disadvantage that the inking "is performed in this case, the saw-tooth regions in the lähe of the side edges of the conveyor belt are alternately sprayed twice with little or inking

Pie hiring aims ₉ to remedy this and one

- 2nd

to enable uniform application of paint over the entire width of the conveyor belt, so that the width of the conveyor belt can be used to the full for workpieces to be sprayed

To solve this problem, the innovation ₉ provides that at least one switching element is arranged in the drive connection or in the area of the [embossing of the injection molding tools ₉ which, when actuated, switches the drive of the conveyor belt on or off for a short time »

Can the! Embossing tool of the injection molding tool be provided with actuating elements? when the carrier reaches the limit position near the side edges of the conveyor belt Actuate the holding element and after reversing the direction of movement release the carrier again »

This ensures ₅ that the conveyor belt during the movement of spray tool carrier is stationary and which is required for the reversal of the direction of movement of the carrier only during the time period _9, is briefly ewegt far erb by such an amount ,, that the subsequent application of paint directly to the the preceding one.

The furnace replaces the continuous belt drive thus through a step-by-step drive »

The switching element for triggering the belt drive can work purely mechanically within the scope of the inventive concept. It can be used as an electrical switch z. B. be designed as a limit switch _s or it can act as a mechanical element on a switch directly or indirectly »

With the mechanical design it is possible to provide the drive of the conveyor belt itself as a kind of ratchet drive or to engage or disengage a clutch purely mechanically ₅ which can be arranged in the drive connection of the conveyor belt »

The control is explained in more detail below _{with reference to the drawings, for example 9} with FIGS. 1 and 2 each showing an exemplary embodiment in a purely schematic manner »

The embodiment shown in Figure 1 contains a purely mechanical switching element »

The workpiece (not shown) is placed on a

port belt 1 passed under the double arm 2 ₉ which carries two injection molds 3 at both ends and is pivotably mounted at A »

The swivel drive takes place via a disk 5 s to which a lever arm 6 is eccentrically articulated, which in turn engages at 7 on the double arm 2 ο

Since the swivel range of the double arm 2 or «of the injection molding tool 3 is generally kept constant, there is the dyeing of irregularly shaped individual pieces The downside is that too much spray medium is consumed and thus wasted because it does not affect what is to be colored Workpiece, but on the [conveyor belt arrives »

TJM 3 adjust the working movement of the spray nozzles to the contour of the workpiece _s is assigned to an ultrasonic barrier 8 each injection tool 3 ^ which scans the Sander of the workpiece and the associated injection mold only be used can _see when it is located above the workpiece ο

With the conveyor belt 1 moving continuously, the

order in the "sawtooth shape exaggerated at 9 take place.

However, the furnace achieves a paint application, like it is indicated schematically at 10 »The adjoining areas that are characterized by different Hatching are indicated, just cover it up slightly or directly abut one another.

In order to achieve this result _s is provided designed as a two-armed lever switch element 11} projecting into the moving range of the Iragers 2 »The carrier 2 is provided with actuators 12 for the switching element 11 '.

To the switching element 11 a push rod 13 is articulated, which transmits its movement through an angle lever 14 on a push rod 15 ₉ which is in turn connected to the drive 16 of the conveyor belt 1 in conjunction "

The drive 16 may be a known to look ratchet driver in this IPaIIe _s connected to the push rod 15 "Instead, this drive

also a clutch to be engaged or disengaged by the push rod 15 ₅ on whose drive side a motor is provided. Instead, the drive 16 can also be an electric motor? whose bin = or where deactivation is triggered by the push rod 15 »

In the embodiment according to Figure 2, a guide bridge 24 is above the conveyor belt 21 for a Slide 22 is provided, which moves in the direction of the arrow 1 is moved by a drive (not shown) ·. The carriage 22 is also the carrier for the paint spraying tools 23 «

With the belt 21 moving continuously, the paint would be applied in the sawtooth shape shown in an exaggerated manner at 29 »To ensure an even application of paint To achieve in accordance with the areas shown schematically at 30, the conveyor belt is also moved intermittently in this exemplary embodiment as soon as the paint spraying tools are close to each other in a distance the side edges of the conveyor belt 21 are located and the direction of movement of the carriage 22 is reversed ..

In the path of movement of the carriage 22 are on both sides

of the tape limit switches 31, which work together with stops 32 on the carriage 22 »These limit switches 31 are via lines 33? 34 connected to the drive of the conveyor belt to cause _s that upon actuation of the limit switch, the drive motor is turned on for a short time 36 and continues to move the conveyor belt 21 by the width of a color application area 30th

The limit switches 31 can also be used to reverse the drive for the slide 22 »

The utility model object is not limited to the illustrated and described exemplary embodiments ξ rather "can details be adapted to the respective purpose? Without deviating from the basic utility, model concept" -,
