Description

Device for applying substance to flat substrates

The invention relates to a device for applying substance to flat substrates, in particular to textiles, carpets, films, comprising at least one application station, which applies the substance in the width direction and longitudinal direction of the substrate, wherein the application station with a substrate receiving device and with a Carrying device is provided which extends at least substantially over the substrate width and having at least one substance spray head, which is formed by a stationary arrangement of distributed over the entire application width provided spray nozzles, and wherein the spray head support means and the substrate in the direction of longitudinal application relatively movable are arranged to each other.

The paint spraying head of the application station of a generic device has a number of substance jetting nozzles which over the entire length of the support z. B. are arranged stationarily along one support beam in one or more rows to simultaneously detect the entire width of a substrate to be provided with substance. A generic device can be equipped for any type of substance application, in particular for printing, but also for coating and / or impregnating. Known devices are printing presses that have multiple printing stations. One or more colors are assigned to the spray head of each printing station. A resting on a blanket substrate is transported continuously and under color nozzles z. B. past at a working distance of a few millimeters to this. These are printing machines with spray nozzles that are digitally controlled by means of electronic circuitry. The machines can be operated at a relatively high speed, since the continuous stationary pressure bar or the spray nozzles arranged stationary over its entire length permit a continuous, uninterrupted longitudinal movement of the substrate, in particular of a web transverse to the pressure bar. This represents a considerable advantage over such digital printing machines, which with a Sliding system works. There namely several carriages with nozzles have to be moved back and forth on a beam in order to detect the printing width. This requires an interrupted sequence of movement of a web under the carriage spray head and thus a limitation of the printing speed, and it can Druckungenauig- z. B. arise in the form of connection strip as a result of a stroke to hub not exact feed movement.

However, in the generic device over the entire working / printing width continuously arranged stationary spray nozzles require special measures for waiting and cleaning. Printing machines for printing on textiles usually have a printing width in the range of 1.5 meters to over 3 meters. If possible, the nozzles should be accessible over the entire working width in one operation and / or at the same time for cleaning and maintenance in order to avoid or substantially reduce stand or set-up times. In the case of color printing presses, a color and / or pattern change should be able to be carried out reliably and quickly, if appropriate without interruption of production. With regard to this aim, digital printing machines are known in which printing stations are each equipped with a spray head support device which can be moved in full, the working / printing width corresponding length perpendicular to the substrate path in a position next to the Druckvoπϊchtung (WO-Al-01 / 40564). Printing presses with such to the side in a straight line movable pressure bar in addition to the parking space for the actual printing press practically once again the same space to the moved out of the printing area pressure bar in their RüsWServiceposition z. B. to relocate on rails. In such a displacement of a pressure bar along a straight line, it must also be considered that the pressure bars of a machine with several stations remain accessible in the service / maintenance position on at least one pressure bar longitudinal side. As a result, the printing stations on the printing machine must in any case be arranged in pairs with a sufficiently large spacing in order to permit walking between two pressure bars in their service / maintenance position (WO-A 1-01 / 40564, FIG. 3). ,

The objectives of the invention are the maintenance of the stationary spray nozzles along the carrying device, in particular with regard to accessibility in the smallest space and To improve the time required for maintenance and thereby affect the operation of the device as little as possible. Several application stations should be able to be arranged at a small distance to the application device. Standbzw. Set-up times should be kept low. In particular, a fast color and / or pattern change should be feasible, if necessary without interruption of production, in printing presses.

The stated objects are achieved according to the invention in conjunction with the features of the device mentioned above in that the spray head support means with the distributed over the application width arranged spray nozzles and a substrate receiving surface of the substrate receiving device relative to each other höhen- displaced by at least one Lifting device are arranged such that the substance spray head in at least one application working position and at least one of the stationary nozzles along the support device for maintenance releasing position passes. By means of the lifting device according to the invention, it is achieved that the spray head carrying device is brought from a working position close to the substrate into at least one distanced position, in which all the spray nozzles along the support beam are simultaneously accessible for cleaning or maintenance. The lifting device is arranged directly on a frame of the application device such that the relative distance between the substrate and the spray head support device for cleaning and waiting by lifting is increased or decreased. Embodiments are conceivable in which the substrate receiving surface is lowered to set up the maintenance position and lifted to produce the working position. The spray head carrying device is accessible for manipulation, cleaning and / or waiting in a confined space.

Particular advantages are obtained in a device having a plurality of application stations arranged in parallel alongside the conveying path of the substrate in a row. The application stations can be particularly dense, that is arranged with a relatively small distance from each other. While one or more spray head carriers are spaced away from the substrate for servicing, the apparatus may continue to operate with at least one further application station for production. A particular embodiment is that the application station or application stations has at least two lifting areas establishing double lifting device for vertical displacement, which is arranged on a stationary device of the application device, a lower first lifting area by at least one working position and expediently at least one rest - and / or maintenance position producing first lifting device and an upper second lifting area by a second lifting device, which raises the spray head support means in at least one upper, externally accessible maintenance position, are arranged, expediently the support means in the upper position in a preferably horizontal position to the side is pivotable.
