Description

Device for use in a tablet coater Description

The present invention relates to a device for use in a tablet coater with the features of claim 1.

According to the prior art, nozzles for applying liquids or suspensions or substances to be sputtered on objects are well known. From DE 10 2004 056 867 AI a nozzle device for a spraying machine is known, which controls an adjustable by external energy control element for controlling the flow ei ^¬ ner spray liquid through at least one channel of the nozzle device.

From FR 2 655 571 A is connected to a spray line nozzle device which is equipped with a plurality of nozzles and has a hand-rotatable Schnellwechselein ^¬ direction for nozzles is known.

From EP 932 448 Bl a nozzle device is known which comprises an input connected to a spray boom input channel and an output connected to a nozzle output channel on ^¬. Furthermore, the nozzle device is provided with an electromagnetically switchable valve which connects the channels during the injection process.

From US 2012/0234942 AI a spray gun is known. The spray gun consists of a nozzle body which can be placed on the shaft of the spray gun. To the

Nozzle body is attached a flat jet cap, in which a liquid outlet opening centrally is incorporated. Laterally at the edge of the flat-jet cap two opposing and approximately perpendicularly projecting horns are arranged in the upper ends

Air outlet openings are arranged. The nozzle body can be connected to the shaft of the spray gun via a receiving unit, to which the nozzle body can be fastened by means of two screws. In order to produce a desired spray pattern of a spray liquid to be atomized, the spray liquid is pressed out of the liquid outlet opening under pressure by means of atomizing air and by means of the air outlet openings of the

Horns of the flat-jet cap directed outgoing airflow. It is in this case a nozzle cone angle is set in a range of 5 ° to 15 ° and the

Flat jet cap in turn has a cone angle in a range of 20 ° to 40 °. By a suitable choice of the atomizing air and the horns of the

Flat jet cap exiting air flow is achieved so that the spray evenly over a wide

Area is sprayed.

From US 2007/0261634 AI is a coating device with a rotating vessel in which to be treated

Particles are recorded, known. In the rotating bowl, a spray nozzle unit is arranged. Of the

Rotating vessel is housed in a housing to be rotated about an axis inclined to a horizontal line. The spray nozzle unit is releasably secured to a pivot arm and the pivot arm is pivotable about a pivot pin provided on the housing

arranged.

From DE 101 42 074 AI a Spritzbeschichtungs- device with a spraying device is known which can be fastened to a support element by a clamping element which is rotatably mounted on one of these two parts relative to both parts. A disadvantage of the known prior art is that the supply of the media supplied to the nozzle for the injection process takes place directly via supply lines to the nozzle and the nozzle body; The pneumatic control lines are also routed directly to or into the nozzle. The nozzle is arranged on a corresponding device. If the nozzle is now to be cleaned or replaced, the aforementioned supply lines for the media and the control lines for the pneumatic control must be disconnected and the nozzle removed. As a result, in the subsequent reinstallation and reinstallation of the cleaned nozzle or a new nozzle, the orientation of the nozzle can not be done in the original orientation and former settings are lost. This is due to the fact that the nozzle on the holding device can no longer be used over the originally set orientation. It must therefore always after each nozzle change or after each nozzle cleaning, in which the nozzle of the

Device is removed, so after removing the nozzle from the device and the reuse of the nozzle, the device and the nozzle readjusted and adjusted to the same spray pattern in relation to

Tablet bed to get as before.

On the nozzle body 2, a closure cap 22 is arranged, which is part of a pneumatic adjusting device for a closing and cleaning needle. The cap 22 opposite a nozzle cap 4 is arranged on the nozzle body 2, which is connected by means of a union nut 18 via the thread 19 with the nozzle body 2. The nozzle body 2 is by means of a clamping screw 6 at the

Nozzle carrier plate 3 fastened. In the nozzle body 2, a bore is provided almost centrally, which the

Nozzle body 2 passes through and corresponds to a hole in the nozzle support plate 3. In the nozzle carrier plate 3, a thread is introduced in the corresponding bore, which with the clamping screw. 6

corresponds. The clamping screw 6 can be screwed into the thread in the bore in the nozzle carrier plate 3. The bore with the thread is in a preferred embodiment of the invention, a blind hole.

In addition, pins and holders are provided, which are not shown in FIG 1, which ensure that the nozzle body 2 only in a predefined position with the nozzle support plate 3 is connectable. It can be the

Nozzle body 2 are arranged only in a unique and predefined position on or on the nozzle carrier plate 3 and secured by the clamping screw 6. By this configuration, only a single clamping screw 6 is necessary to fix the nozzle body 2 on the nozzle support plate 3 and secure. As in the case of

Cleaning the nozzle body 2 only this is removed, the nozzle support plate 3 remains in the preset position, the orientation of the

Nozzle body 2 when re-attachment to the

Nozzle carrier plate 3 after cleaning the nozzle body 2 not changed. It must therefore be made no Neuj ustierung. The supply lines for media to be atomized or sprayed by the device 1, and the

Atomizing medium, which is used for atomizing the medium, and the pneumatic control lines are fed to the nozzle body 2 exclusively via the nozzle carrier plate 3. On the nozzle body 2 are not arranged on ^¬ management lines. The nozzle body communicates only with the nozzle support plate 3.

Between the nozzle body 2 and the nozzle support plate 3, a flat seal or an O-ring seal is provided, which serves for sealing. This is not shown in FIG.

The nozzle cap 4 of the device 1, which on the

Nozzle body 2 can be fastened by means of a union nut 18, characterized in that a bore 9 is centrally placed in the nozzle cap 4. The nozzle cap 4 has a flat surface section 10 in the upper region in which the bore 9 is arranged. On or in the flat surface portion 10 are symmetrically to the axis of the nozzle cap 4, two outlet openings 11, 12 are introduced, which obliquely, preferably in one

In an advantageous embodiment of the invention, the nozzle cap 4 is a nozzle cap of the so-called ABC technology without horn-shaped air leaks. The nozzle carrier plate 3 has a clamping screw 5. The clamping screw 5 can be screwed into the nozzle carrier plate 3 in a bore with a thread introduced in the bore. There is also a sliding guide 7 in or on the nozzle carrier plate 3, which is not shown in FIG. The bore for the clamping ^¬ screw 5 passes through the nozzle-carrying plate 3 and flows into the slide 7, so that the clamping screw 5 is screwed into the nozzle-carrying plate 3 and engages in an on ^¬ screwed-in state in the slide 7, so that an element that is is located in the sliding guide 7, can be clamped by the clamping screw 5 in the sliding guide 7, so that the nozzle plate 3 is firmly fixed to this element via the clamping screw 5. The sliding guide 7 forms the inserted element from an abutment about whose center the nozzle support plate 3 is rotatable. By choosing the configuration of the sliding guide 7, however, an inclination of the nozzle carrier plate 3 relative to the element can also take place.

Is the nozzle support plate aligned with the 3 arranged on it nozzle body 2 appropriately set and adjusted, so this position is fixed by means of the clamping screw ^¬ 5 and the nozzle-carrying plate firmly clamped to the element. 3 The advantage of the invention is now that, by the clamping screw 5 and sliding guide 7, the nozzle-carrying plate 3, and thus the on the nozzle carrier plate 3 is ^¬ arranged nozzle body 2 and thus the device 1 can be fixed in an adjustable orientation member. The nozzle support plate 3 is attached to the element, which is for example the arm of a tablet coater, and the

Feed lines are connected to the nozzle support plate 3. Then, the nozzle body 2 is arranged on the nozzle support plate 3 and fixed by means of the clamping screw 6. By means of the sliding guide 7 and the clamping screw 5, the nozzle support plate 3 and with it the entire device 1 together with the nozzle body 2 are adjustable in their orientation and thus adjustable. But if the nozzle support plate 3 is fixed by means of the clamping screw 5 on the element which is located in the sliding guide 7, so the nozzle body 2 can be removed and arranged again, without thereby setting a once

Orientation of the device 1 would be changed. Thus, after replacement or cleaning of the nozzle body 2, the device 1 can continue to be used without the device 2 or the spray pattern of the device 1 having to be readjusted.

Thus, when changing the nozzle body 2 or a removal of the nozzle body 2 for cleaning purposes and subsequent reinstallation of the nozzle body 2 the

Orientation of the nozzle body 2 and thus the entire device 1 and the set spray pattern the same as before.

The element to which the device 1 can be fixed via the clamping screw 5 and the sliding guide 7 is preferably an arm or a device on an arm of a tablet coater. Preferably, the element is designed in the form of a rod profile.

The supply of the device 1 to be sprayed media and the lines for the pneumatic

Control are arranged exclusively on the nozzle carrier plate 3. This avoids that after a disassembly and / or reassembly of the nozzle body 2 results in a change in the spray pattern of the device 1, since the nozzle body 2 is again arranged exactly on the nozzle carrier plate 3.

In a direct attachment of the nozzle body 2 to an arm of a tablet coater and a direct Zu ^{¬ management of} the media and the control lines, these lines must be removed, then the nozzle body from the arm of the tablet coater must be solved and can only then be removed. When installing a new or the cleaned nozzle body initially the nozzle body must be fixed to the arm of the tablet coater again, ^¬ then the previously dismantled lines must be reconnected. Through these different steps, various forces act on each

Nozzle body and the nozzle body no longer has the same position and orientation as before disassembly. Therefore, the entire device must be realigned and set up to reproduce the originally set spray pattern.

In the embodiment according to the invention but only the clamping screw 6 must be solved and the nozzle body 2 can be removed. In a Reinstallation only the nozzle body 2 must be placed on the nozzle support plate 3 and locked with the clamping screw 6. A

Re-adjustment is not required.
