The invention relates to a device for spraying antique paint on the edges or seams of loose shoe uppers by means of a fixed, adjustable in several levels Spray gun, the upper part of the shoe being forced to move forward by two rotating conveyor rollers will.

So far, the spraying of antique paint has not already been done on the loose shoe upper, but only on the finished shoe itself, using a hand-held spray gun.

This requires a lot of skill on the part of the operator, and despite the greatest care it is inevitable that the antique paint is also sprayed on places where it is undesirable. Furthermore, it is very difficult to apply an evenly distributed paint application to the desired locations . achieve.

In devices for applying luminous material with applicator pens, it is known to control the compressed air supply for the applicator pen by means of a foot-operated device. However, the spotting pin is guided in such devices on the _f workpiece with the hand. Accordingly, no inevitable workpiece feed is provided for this, which takes place, as in the case of the subject matter of the invention, by two conveyor rollers that can be opened and closed by means of a further foot lever. Such devices also do not have an adjustable edge guide for changing the edge distance.

In contrast, the device designed according to the invention has a displaceable and definable stop and two independently operated foot levers, one of which is used to manufacture one positive delivery connection and the other for supplying compressed air to the spray gun serves. By operating both foot levers independently, it is possible to spray on of antique paint during the conveying to be interrupted in places, especially one if necessary to achieve a fashionable effect.

Further details of the invention emerge from the drawing and the description. It shows

Named as inventor:

Kurt sewing, Barmstedt near Hamburg

A £ -shaped bracket 2, which corresponds in its outer shape to a column sewing machine, is attached to a work table 1. A lower arm 3 of the £ -shaped bracket 2 has a slender column 4 in which a positively driven roller 5 is mounted, which protrudes slightly above the column 4 upwards. An upper arm 6 of the [[-shaped bracket 2 is provided with a guide 7 in which a support rod 8 for holding a roller presser 9 is slidably mounted. At its upper end 10, the support rod 8 has a thread for fastening two adjusting nuts 11 and 12. In addition, the support rod 8 is offset and, in its thinner area, is provided with a groove 13 for receiving a locking ring 14. A fork lever 15 engages between the offset collar of the support rod 8 and the securing ring 14, which is kept constantly tensioned against a further disk 18 in the rest position by a compression spring 16, with the addition of a disk 17.

The roller presser 9 consists of a cranked holder 19 and a conical roller 20, which revolve around a pin 21 can rotate freely.

The fork lever 15 has two arms and is mounted in the guide 7 by means of a bolt 22.

In the protruding from the guide 7 end 23 of the fork lever 15 engages a by a foot lever 24 influenceable Shift lever 26 on. The shift lever 26 is fastened to the boom 6 by means of a bolt 27 is stored. A torsion spring 28 tries to keep the shift lever 26 in the rest position so that that the support rod 8 remains with the roller presser 9 in the raised position (Fig. 3).

A chain 30 is hooked into the other end 29 of the shift lever 26 and is connected to the foot lever 24 is. The torsion spring 28 is so strong that it also lifts the foot lever 24 in the rest position Holds position. By stepping down on the foot lever 24, the end 29 of the shift lever 26 is opened moved downwards, whereby the support rod 8 with the roller 20 of the roller 5 is moved. Means the two adjusting nuts 11 and 12 can limit the downward movement of the support rod 8, so that the two rollers 5 and 20 do not touch on their outer circumferential surfaces. The distance will adjusted so that the thinnest parts of the shoe upper are just promoted while at increasing material strength by the spring 16 a compensation takes place without the operator his to change the force exerted on the foot lever 24.

A spray gun 32 can be displaced in several directions on the boom 6 in order to receive a spray gun 32 and pivotable bracket 31 is provided. As a result, the spray gun 32 can be aligned in such a way that that the ink jet emerges from an outlet opening 33 behind the rollers 5 and 20, with the corresponding Setting a color-free border can also be achieved. For setting the exact distance from the edge and for better guidance of the shoe upper there is an adjustable stop on the column 4 34 provided.

The spray gun 32 is provided with two feed lines 35 and 36, one of which with the paint container

37 and the other is connected to the foot valve 38. In the rest position, the supply line 36 is relieved of compressed air and is activated when the foot valve is operated

38 pressurized with compressed air from the line 39. By the flow of compressed air in line 36 is the Antique paint carried along through line 35 from paint container 37 and from mouthpiece 33 of the Spray gun 32 is applied finely sprayed onto the shoe upper.

Conveniently, a pressure reducing valve 40 is attached to the workbench 1 to the Set the compressed air taken from the compressed air system to the desired working pressure.

Operation of the device

The operator places the shoe upper 41 on the roller 5 of the column 4 against the stop 34 and actuates the foot step 24, whereby the roller 21 moves downwards and thus the shoe upper 41 inevitably is advanced. As soon as the advance occurs, the foot valve 38 is actuated and thus antique color applied to the edge of the shoe upper 41 in the manner as shown in FIG. 4 at 42 is shown.

Claims (1)

Claim: Device for spraying antique paint on the edges or seams of loose shoe uppers by means of a spray gun using one for spraying adhesives known device by means of an adjustable spray gun and two conveyor rollers, one of which fixedly mounted and the other fixedly mounted conveyor roller by non-positive means can be moved, characterized in that that the characteristics a) one (5) of the conveyor roller (5 and 20) is a movable and fixable stop (34) assigned, b) a foot lever is used to adjust the other conveyor roller (20) in relation to the first (5) (24) provided, c) for the application of compressed air to the spray gun (32) is a valve through another Adjustable foot lever (38), are united with each other.
