Description

The invention relates to an adapter plate for connecting a spinning pump device and a line for conveying a spinning fluid for synthetic fibers according to the preamble of claim 1 and an associated spinning pump system in which the adapter plate is used.

For the production of synthetic fibers and filaments, such as spandex fibers, high-precision spinning pump devices are usually used, which are designed on an adapter plate for connecting the spinning pump device on the one hand and for connecting the feed line. External gear pumps, in particular, are used for the spinning pump devices, such as in DE 10 2016 013 684 A1 described, which are constructed on the principle of a planetary gear pump.

The driving gear of the planetary gear pump is connected to a driving source that meshingly drives planetary gears arranged on its outer periphery.

In the combing pockets formed by the external gear wheels and the drive gear wheel, the spinning fluid is then conveyed from a supply line into an adapter plate which has fittings, by means of which the conveying lines can be coupled to the respective spinnerets.

The number of external gears determines the number of feedable lines. For example, with eight planetary gears, eight lines can also be fed. The adapter plate must then be provided with an appropriate number of fittings.

Such planetary gear pumps can also be arranged in series one behind the other. It is currently possible for adapter plates to be provided with up to forty fittings.

However, this comes up against both technical and spatial limits.

The more fittings are to be accommodated in the adapter plate, the larger their circumference and thickness must be dimensioned. In addition, the assembly and disassembly of line connections becomes more complex due to the larger number of fittings.

With the current adapter plates, it is difficult to increase the pump capacity by additional spinning pump devices, since an adapter plate that is too large is difficult to handle and set up.

It is therefore the object of the invention to provide an adapter plate and a pumping system with the adapter plate that is easy to maintain and yet allows the pumping capacity to be increased through additional lines without requiring additional space.

With regard to the adapter plate, this object is achieved according to the invention with an adapter plate having the features of claim 1 .

The adapter plate according to the invention can be fitted with pump devices on both sides and provides additional connection areas for a plurality of lines for conveying a spinning fluid for synthetic fibers.

According to one aspect of the invention, an adapter plate is provided for connecting a spinning pump device and a line for conveying a spinning fluid for synthetic fibers, the adapter plate defining a first connection side and a second connection side different from the first connection side, and on the first connection side a line connection section for fluid-tight connection of the line and a spinning pump connection section for fluid-tight connection of the spinning pump device is formed, wherein a second spinning pump connection section for fluid-tight connection of a second spinning pump device is formed on the second connection side.

With the adapter plate according to the invention, the spinning pump devices can be exchanged more easily. There is no need to dispose of the tubing attached to the fitting when changing spin pump assemblies. In addition, the spinning pump devices can be exchanged independently of one another.

Advantageous developments of the adapter plate result from features and feature combinations of the respective dependent claims.

According to a development of the adapter plate, the adapter plate has a plurality of fittings on the first connection side in the line connection section, which at least partially surround the first and/or second spinning pump connection section in a circle.

A fitting is to be understood here as a connection piece, preferably with a thread, which is suitable for the fluid-tight installation of a pipe and/or hose line.

The respective line can be coupled and uncoupled without problems by means of the thread. A positive and non-positive screw fit for a fluid-tight connection with the adapter plate can be produced by means of the thread.

According to a development of the adapter plate, the plurality of fittings extends essentially parallel to the direction of the axis of rotation of the spinning pump device.

According to a further development of the adapter plate according to the invention, the adapter plate is designed with channels for supplying and draining off the spinning fluid to be conveyed.

According to another development of the adapter plate according to the invention, a through opening is formed in the adapter plate to accommodate at least one drive shaft of the first and/or the second spinning pump device.

According to a further development of the adapter plate, a drive shaft coupling bushing is arranged in the through-opening.

According to another development of the adapter plate according to the invention, the first spinning pump device can be driven directly with the drive shaft of a spinning pump drive and the second spinning pump device can be driven indirectly with the drive shaft of the first spinning pump device.

In a further development of the adapter plate according to the invention, the first connection side is defined by an adapter part plate, in which at least one line connection section and a fitting for fluid-tight connection to a line is provided.

According to another development of the adapter plate according to the invention, the adapter plate is formed by the first and a second partial adapter plate, which each have line grooves and line bores designed to complement one another and, in an assembled state, form channels for distributing the spinning fluid to be conveyed to and from the respective spinning pump device, with the spinning pump connection section for fluid-tight connection of the second spinning pump device is formed in the second adapter part plate.

According to another development of the adapter plate according to the invention, the first and/or the second spinning device has a plurality of external gear pump plates arranged in series, with each external gear pump plate having at least one driven and one driven external gear, with the driven gear and the driven gear standing with the associated external gear pump plate , wherein the number of the plurality of fittings essentially corresponds to the number of driven gears in the first and/or two spinning pump devices.

A driven gear is to be understood here, for example, as an external gear which is in meshing engagement with a driven external gear.

According to another development of the adapter plate according to the invention, the spinning pump device has a plurality of external gear pump plates arranged in series, each external gear pump plate having at least one driven and one driven external gear, the driven gear and the driven gear being in fluid communication with the associated external gear pump plate, wherein the number of the plurality of fittings in the first and/or the second adapter plate essentially corresponds to the number of the driven gear wheels in the first and/or the second spinning pump device.

The sectional view of 6 shows an interior view of one of the external gear pump plates 40 of the first and second spinning pump devices 4.1, 4.2 arranged in series with the driven sun gear 43 and the driven planetary gears 44. In addition, the distribution of the synthetic melt from the central passage connection opening 9 to the distribution channels 91 is also indicated.

The driven gear 43 drives the driven gears 44 . The driven gear 43 and the driven gears 44 are arranged according to a planetary gear train. Due to the meshing action of the gears with each other, a predetermined quantity of the synthetic fluid is taken from branches of the central passage connection opening 9 and conveyed from the outer circumference of the driven gears to the discharge channel 92, which is in fluid-tight communication with the fitting of the respective adapter plate 5 or 6.

The number of fittings 7 of the first adapter plate 5 is determined by the number of driven or conveying gear wheels 44 or pumps, so that a plurality of connection lines can be supplied with the synthetic fluid in a simple manner.

The number of fittings 7 of the first adapter plate 5 can also have a larger or smaller number of fittings, depending on how many external gear pump plates 40 and conveying gears 44 are provided.

With the adapter plate 5 according to the invention, an inexpensive and simple expansion of existing pump systems is possible.
