Description

The invention relates to a preparation device and a method for Apply a preparation consisting of several sub-components on a running thread according to the preamble of claim 1 and Preamble of claim 12 and a preparation pump for implementation of the method according to the preamble of claim 16.

When producing a freshly spun multifilament thread, it is necessary to provide the thread with a preparation order for further processing. The thread can thus be left over without damaging the individual filaments Safely guide contact surfaces such as thread guides or godets. To the another, the preparation order leads to the filaments of the Thread. Liquid emulsions are used as the preparation agent joining several sub-components e.g. Water and oil produced become.

A preparation device is known, for example, from US Pat. No. 3,783,596. in which the emulsified preparation in a storage container Preparation of a thread is held. There is one on the reservoir Connected conveyor that dosed the preparation in a Volume flow to a wetting device promotes. The Wetting device applies a preparation job to the thread. The The conveyor is designed as a preparation pump. Such Preparation pumps are single pumps with only one pump outlet or designed as multiple pumps with several pump outlets. On everyone Pump outlet is a connection line to a wetting device connected. The emulsified is thereby emulsified via a pump inlet Preparation agent fed to the preparation pump.

However, emulsified preparation agents dosed in this way have only a limited number Shelf life, since bacteria accumulate with increasing storage time. The Bacteria lead to outgassing, which can be noticed in the form of bubbles. These gas inclusions in the preparation cause in the Wetting device a wrong application on the thread, so that the thread Has preparation gaps that result in filament breaks. In addition, in the entire preparation device is cleaned at regular intervals required. Another disadvantage of the known preparation device lies in that a change in the mixing ratio of the sub-components of Preparative only after the remaining amount has been used up or after the Remaining quantity is possible.

In the known preparation pumps, the emulsified preparation is in dosed a predetermined mixing ratio promoted. Here is also disadvantageous that a change in the mixing ratio of Subcomponents of the preparation means a depletion of the stock and cleaning of the preparation pump requires.

The invention is therefore based on the object Preparation device and a method of the type mentioned above to further develop that aging of the emulsified preparation does not can occur.

Another object of the invention is to provide a flexible preparation pump create a change in the mixing ratio of the sub-components of the Preparing the preparation in a simple way.

The object is achieved by a preparation device with the Feature of claim 1, by a method having the feature of claim 12 and by a preparation pump with the features of claim 16 solved.

The invention offers the particular advantage that the subcomponents are only immediately before applying the preparation to the questions be brought together. The emulsion arises shortly before application the thread. For this purpose, the sub-components of the preparation are shown in kept in separate containers. Each of the containers is through a line with the Connected conveyor, which has an inlet channel for each line. Within the conveyor, the sub-components are resulting partial streams merged into a main stream. The Sub-components of the preparation are therefore only in the main stream mixed together and then to the wetting device for Dissect the thread.

A certain mixing ratio between the sub-components To be able to adjust and comply, according to an advantageous development of the invention according to claim 2 and claim 13 a subcomponent in it Quantity metered to another sub-component and together blended. Especially in the event that a sub-component in only very small amount must be added to a base component, can by dosing the sub-component with a small amount the predetermined Set the mixing ratio safely.

In a particularly advantageous development of the invention, everyone Partial stream assigned a separate dosing agent, the dosing agent are independently controllable. This allows a given Mixing ratio in a very high accuracy and constant Quality set and adhered to. By changing the Individual doses of the dosing agent can be the mixing ratio of Easily change sub-components. The dosing agents can For example, be designed as metering valves between the lines the reservoir and the conveyor are arranged.

To make the construction of the invention as compact as possible To allow preparation device, it is proposed to each inlet channel assign a separate dosing agent to the conveyor.

The embodiment variant according to claim 5 is particularly advantageous. in which the dosing means are each formed by a controllable dosing pump are. The funding institution thus takes on the function of funding and Dosage at the same time. Another advantage is that the preparation agent is conveyed to the wetting device with a predetermined dosage. The The dosage to be observed for application to the thread is made up of the Sum of the individual doses of the partial flows together.

In order to obtain the most intensive possible mixing of the sub-components, the development of the preparation device according to the invention Claim 6 particularly advantageous. Here, the main stream is through a Mixing chamber led.

One or more mixing agents are advantageously arranged in the mixing chamber, so that the sub-components of the preparation agent evenly with each other can be mixed.

However, it is also possible to use a dynamic mixer as a mixing agent to use. For this purpose, rotating mixing agents are used in the mixing chamber Mixing of the sub-components used.

The preparation device according to the invention has for applying the Preparing agent on the running thread a wetting device. Such wetting devices can, for example, as one Preparation pen, a preparation nozzle or a roller preparation be, in particular the pen preparation and the nozzle preparation one Require metering of the main stream, which is advantageous from the individual metering of the subcomponent results.

The preparation pump according to the invention has the advantage that the Partial components of the preparation agent only within the preparation pump be brought together and mixed. The emulsion is thus formed for a short time before application to the thread in the mixing chamber of the preparation pump. For this purpose, the preparation pump has several inlet openings to the mixing chamber on. The separate subcomponents are undosed in the inlet openings or metered into the mixing chamber. In the mixing chamber are between the inlet openings and the actual pump inlet several Mixing elements arranged, which lead to an intensive mixing of the Sub-components leads. Thus lies at the pump inlet, in one predetermined mixing ratio before merged preparation, that by the funding of the preparation pump in one dose Volume flow is pumped to a pump outlet.

The preparation pump according to the invention can thus be used for stockpiling of an emulsified preparation. This will make the switch as well the change in the concentration of the preparation in a simple manner possible. A cleaning of the preparation supply lines to the Preparation pump when changing the preparation or because of Bacteria formation in the preparation is also eliminated because of the Mixing chamber supply lines are connected, each one Guide part of the preparation.

In a particularly advantageous development of the preparation pump, the Mixing elements at least partially on a protruding into the mixing chamber Mixing shaft attached. The mixing shaft is driven in rotation so that a intensive and uniform mixing of the sub-components of the Preparative occurs.

In a particularly preferred embodiment variant of the invention Preparation pump is the mixing shaft and the funding by a joint drive driven. So that the dosage and the Influence the mixture through a drive control.

It is particularly advantageous if the funding is provided by a Drive shaft is drivable, which projects into the mixing chamber at one end and forms the mixing wave. This requires that the mixing chamber and the funding is aligned with each other. This results in a particularly compact design of the preparation pump.

To be independent of the speed of the conveyor and therefore independent of the metered volume flow an intensive mixing of the sub-components to achieve the preparation in the mixing chamber is the formation of Invention according to claim 20 particularly advantageous. Here is the drive shaft and the mixing shaft connected to each other by a transmission gear. This means that a common drive is retained, but the mixing shaft can be used operate at significantly different speeds. The mixing shaft is preferred with driven at higher speeds.

To achieve a uniform, low-pulsating volume flow, the with can be metered with high accuracy, the funding of the preparation pump preferably formed by one or more pairs of gears. When using a Multiple pumps with several pairs of gears each pair of gears is its own Pump outlet assigned. The gear pairs are supplied via the central pump inlet. In such multiple gear pumps Drive wheels driven together via a drive shaft.

The preparation pump according to the invention is for supplying any Wetting device such as preparation pens, preparation nozzles or also roller preparation suitable.

Further advantages of the invention are in the following with reference to the attached drawings based on some embodiments described.

In the line 8.1 is between the conveyor 5 and the reservoir 1 Dosing means 7.1 arranged. In line 8.2 is also between the Storage container 1 and the conveyor 5 arranged a dosing means 7.2. The dosing means can be used as electromechanical valves or electrically driven pumps.

The conveyor 5 has two inlet channels 9.1 and 9.2 on an inlet side to which the lines 8.1 and 8.2 are connected. The inlet channels 9.1 and 9.2 are connected to a conveyor 6 in the conveyor 5. The Funding 6, for example from one or more gear sets exists, is on the opposite side of the inlet channels 9.1 and 9.2 with an outlet channel 19 connected. Is on the outlet side of the conveyor 5 a line 13 is connected to the outlet duct 19. Within the For the device 5, a mixing chamber 10 is formed, which is the outlet channel 19 divides into two sections, with a section between the Conveying element 6 and the mixing chamber 10 extends and the second section of the The outlet channel extends between the line 13 and the mixing chamber 10. In the mixing chamber 10, a plurality of mixing elements 11 are arranged. The Mixing elements 11 are designed as webs that overlap are mutually arranged so that a strong deflection of the flowing Preparative is enforced.

The line 13 connects the conveyor 5 to the wetting device 14. The wetting device 14 is designed as a pen preparation. This points the wetting device 14 has a thread guide 15. The thread guide 15 has at its end a thread running track 16 in which a thread 18 with Contact is made. A channel 17 opens into the thread running track 16. The channel 17 is connected to line 13 at the opposite end.

In the preparation device shown in FIG. 1, a Preparative used, consisting of two sub-components 3.1 and 3.2 put together. For this purpose, the sub-components 3.1 and 3.2 of the separate containers 2.1 and 2.2 added. Through the outlets 4.1 and 4.2 and the lines 8.1 and 8.2 reach the sub-components 3.1 and 3.2 the funding 6. The amount of sub-component 3.1, which is the Fürdermittel 6 arrives, determined by the dosing means 7.1. The amount of Subcomponent 3.2 is determined by the dosing agent 7.2. Will that Preparations, for example, in part from subcomponent 3.1 and mixed into two parts from sub-component 3.2, that would Metering valve 7.2 compared to the metering valve 7.1 double the amount Allow subcomponent per unit of time. With that, a first dosed occurs Partial flow of the component 3.1 in the inlet channel 9.1 in the conveyor on. The metered partial flow of the partial component 3.2 enters the inlet channel 9.2 on.

The main flow of the preparation is through the Delivery rate of the conveyor 6 to a predetermined wetting flow set. A uniform preparation of the thread 18 is thus achieved.

2 is another embodiment of an inventive Preparation device shown with a pen preparation. The Preparation device is essentially identical to that Embodiment according to Fig. 1 formed. In this respect, the previous one Description referred to, and only the differences below exposed. The preparation device in turn consists of a Storage container 1 of a conveyor device 5 and a wetting device 14. The conveyor 5 is with an inlet channel 9.1 via line 8.1 a container 2.1 connected. Between the conveyor 5 and the Container 2.1 is in line 8.1 a dosing agent 7 for dosing in the Line guided sub-components of the preparation agent arranged. On second inlet channel 9.2 of the conveyor is connected via line 8.2 to a second separate container 2.2 coupled. Inside the conveyor is on a mixing chamber 10 is formed on the inlet side, into which the inlet channels 9.1 and 9.2 lead. A plurality of mixing elements 11 are located within the mixing chamber 10 arranged. The mixing chamber 10 is connected to an outlet channel Funding 6 connected. The funding 6 is via the outlet channel 19 and Line 13 connected to the wetting device 14.

In the preparation device shown in Fig. 2, that in the container 2.2 available component of the preparation directly over the Line 8.2 and the inlet channel 9.2 led to the mixing chamber 10. The second Partial component of the preparation, which is contained in the container 2.1, is dosed in quantity into the mixing chamber 10 via a dosing agent 7.1 guided. Within the mixing chamber 10, the sub-components are together blended and then passed through the funding 6, which in this case dispenses the amount required for the wetting device. This Arrangement has the advantage that the dosage of the sub-components Determination of the mixing ratio regardless of the dosage of the for the preparation required emulsion is adjustable. However, it is also possible that the conveyor 5 several arranged side by side Wetting devices 40 supplied. Any wetting device can do this a separate dosing agent can be assigned.

In Figure 3 is another embodiment of an inventive Preparation device shown schematically. The components with the same Function were given identical reference numbers.

The preparation device contains a conveyor 5, in which the Funding means are formed by two separate metering pumps 21.1 and 21.2. The metering pump 21.1 is operated via an external device 5 arranged motor 22.1 driven. The metering pump 21.2 is driven about the engine 22.1. The motors 22.1 and 22.2 are over a Control device 20 controlled.

In the conveyor 5, the metering pump 21.1 is the inlet channel 9.1 and the Dosing pump 21.2 assigned to the inlet channel 9.2. The pump outlet of the Dosing pump 21.1 is connected to the outlet channel 31.1. The pump outlet the metering pump 21.2 opens into the outlet channel 31.2. The outlet channels 31.1 and 31.2 are brought together in a mixing chamber 10. In the Mixing chamber 10 are static mixing elements 11 and a dynamic one Mixer 12 included. The dynamic mixer 12 can for example be formed by a rotating shaft with mixing elements. On the The outlet side of the conveyor 5 is via the outlet channel 19 Mixing chamber 10 connected to a line 13.

The line 13 leads to a wetting device 14, which acts as a nozzle preparation is trained. For this purpose, the wetting device 14 has a nozzle 23 contains a nozzle channel 24. The nozzle channel 24 ends in a nozzle opening 32, which sprays the preparation agent at a distance from a running thread 18. The nozzle channel 24 is connected to the line 13.

On the inlet side of the conveyor 5, the inlet channel 9.1 is through the Line 8.1 connected to the container 2.1. The container 2.1 contains one Subcomponent 3.1 of the preparation. The inlet duct 9.2 is over the Line 8.2 connected to the container 2.2. The container 2.2 contains another Subcomponent 3.2 of the preparation.

In the preparation device shown in Figure 3, the Subcomponents 3.1 and 3.2 of the preparation agent by means of Metering pump pumps 21.1 and 21.2 metered in their quantity and simultaneously by the metering pumps 21.1 and 21.2 as partial flows into a mixing chamber 10 promoted. The promotion and metering of the partial flows is via the Control device 20 controlled. For this purpose, the motor 22.1 and the motor 22.2 frequency controlled by the control device 20. As a result, the partial flows in a certain quantity ratio to each other into the mixing chamber 10 promoted. In the mixing chamber 10 follows through the mixing elements 11 and Mixer 12 an intensive mixing of the sub-components. That as Emulsion-mixed preparation agent then passes through the outlet channel 19 into the connected line 13. By means of the metering pumps 21.1 and 21.2 generated delivery pressure, the preparation agent from the nozzle channel 24th sprayed out of the nozzle opening 32 as a fine mist. The preparation drops sit evenly on the passing thread 18.

The metering pumps 21.1 and 21.2 can be formed, for example, by micropumps, which can meter a liquid in a wide range from a few to several thousand drops per second. Depending on the thread thickness, the preparation orders can be applied in the range from 1 cm ³ per minute to 20 cm ³ per minute without any problems. In such micropumps gear sets or diaphragms are used as funding.

Another exemplary embodiment of FIG Preparation device according to the invention shown as a roller preparation. The preparation order on the thread 18 is here a rotating one Roller 28 applied, on the circumference of which the thread 18 is guided with contact. The roller 28 dips into a section with a preparation agent filled container 29 a. This makes the surface of the roller 28 uniform wetted with the preparation. The preparation agent is in the container 29 introduced via a conveyor 5. For this the level of Preparation agent in the container 29 monitored by a level switch 27. The Level switch 27 is coupled to a control device 30. The Control device 30 is connected to a motor 26. The motor 26 drives Funding 6 of the conveyor 5.

The funding 6 is via three separate inlet channels 9.1, 9.2 and 9.3 and the respectively connected lines 8.1, 8.2 and 8.3 with three containers 2.1, 2.2 and 2.3 connected. There is one in each of the containers 2.1, 2.2 and 2.3 Contain subcomponent 3.1, 3.2 and 3.3 of the preparation. For dosage or to adjust the mixing ratio are in the Connecting lines 8.1, 8.2 and 8.3 each have a metering valve 25.1, 25.2 and 25.3 arranged. The metering valves 25.1, 25.2 and 25.3 can be in their Manually change the flow rate continuously. Thus the Sub-components 3.1, 3.2 and 3.3 in the specified ratio to the Funding 6 out. In the funding 6, the partial flows of Sub-components 3.1, 3.2 and 3.3 brought together to form a skin stream and conveyed via an outlet duct 19 via line 13 to the container 29.

The device shown in FIG. 4 is mixed and conveyed of the sub-components directly in the funding 6 of the conveyor 5. Das Funding 6 can for example by a planetary gear set be educated in which each partial flow is promoted by a wheel set and are then merged into a main stream. A promotion of However, partial components only take place as soon as the level of the preparation agent is in the container 29 has reached a limit which is set by the level switch 27 is detected. The control device 30 is controlled by the level switch 27 signals that a filling of the container 29 is required. Thereupon will the motor 26 activated, so that a promotion of the sub-components by Funding 6 occurs and the container 29 then with the Preparative is filled up. Once a maximum level of Preparation agent is reached in the container 29, is on the level switch 27 and the control device 30, the motor 26 stopped. There is no further Promotion of the sub-components.

The embodiments shown in Figures 1 to 4 are in the Combination of the conveying device 5 and the wetting device 14 exemplary. The wetting devices 14 shown and the Conveyors 5 can optionally be combined in a manner not shown become. In addition, several wetting devices can work together be connected to a conveyor. The wetting devices are supplied parallel to each other.

The preparation device according to the invention and the inventive Methods are not limited to one component per container of the preparation is stored. A container can also already have one Mixture of several sub-components may be included. The mixture can be then just before application to a thread another sub-component z. B. add an additive.

FIG. 5 schematically shows a first exemplary embodiment of a Preparation pump according to the invention shown. The preparation pump could for example serve as a conveyor 5 in the preparation device Fig. 2 can be used. The preparation pump is a multiple pump executed and consists of the assembled sub-pumps 122.1, 122.2, 122.3 and 122.4. A conveying means 102 is embedded in each of the sub-pumps 122. The funding 102 consists of the gears 109, 110 and 111. Thereby forms the gear pair 109 and 110 and the gear pair 111 and 110 one Pump unit that doses and conveys a volume flow. Each sub-pump 122 thus forms a double pump with two separate pump outlets 114. The in Figure 5 pump is thus designed as an 8-fold pump. All Sub-pumps 122.1 to 122.4 are all with the pump inlet 103 in Connection. The partial pumps 122.1 to 122.4 are driven jointly by a drive shaft 108. The drive shaft 108 is at one end via a Coupling 116 connected to a motor 117. On the opposite The drive shaft 108 is at the end by means of a bearing 115 in the pump housing 101 stored. The respective central gearwheels 110 are on the drive shaft 108 of the sub-pumps 122.1 to 122.4 and are fastened by the drive shaft 108 driven. For this purpose, the partial pump 122.1 is shown in a sectional view in FIG and the sub-pumps 122.2 to 122.4 shown in a view.

The gear wheels 109 are on a shaft 113 and the gear wheels 111 are on one Shaft 112 rotatably mounted.

Axial extension of the drive shaft 108 is in the pump housing 101 a mixing chamber 104 is formed immediately in front of the pump inlet 103. The Mixing chamber 104 has two at the end of pump housing 101 Inlet openings 105 and 106, which open into the mixing chamber 104. Within the mixing chamber 104 are a plurality of mixing elements 107 on the pump housing 101 attached. The mixing elements 107 are opposite, for example staggered and overlap inside the Mixer housing, so that those entering the inlet openings 105 and 106 Volume flows by repeatedly deflecting the mixing chamber 104 run through. On the opposite to the inlet openings 105 and 106 The side of the mixing chamber 104 is the pump inlet 103 in the pump housing 101 brought in. The pump inlet 103 forms the outlet for the Mixing chamber 104.

In order to explain the function, the feeding of the Preparation pump shown through the inlet openings 105 and 106. Through the Inlet opening 105, component A of the preparation is undosed, for example from a supply line 118, branched off and into the Mixing chamber 104 initiated. The sub-component A could for example Be water. A second sub-component B of the preparation is over the second inlet opening 106 is metered into the mixing chamber 104. For this is the sub-component B, for example an oil, from a container 120 through a metering pump 119 with a metered volume flow into the mixing chamber 104 initiated. The metering pump 119, which has a regulated motor 121 is driven, can be designed as a single or as a multiple pump his.

The subcomponents A and B become one within the mixing chamber 104 Emulsion or a mixture mixed. The emulsified preparation then arrives via the pump inlet 103 to the conveying means 102 Funding means 102 divides the main flow into eight metered Individual flows through the pump outlets to the - not shown here - connected wetting facilities are promoted. The crowd will predetermined by the speed of the drive shaft.

In order to be able to set a specific mixing ratio between the sub-components A and B, the speed of the metering pump 119 is controlled as a function of the speed of the drive shaft 108. For example, in order to mix in the component B with a volume fraction of 10%, the metering pump 119 would have to be set to a volume flow of 0.25 cm ³ / minute given a total delivery rate of the preparation pumps of 2.5 cm ³ / minute.

The motor 121 and the motor 117 are therefore advantageous with one Control device connected in which the metered main volume flow and the mixing ratios are predetermined, so that a corresponding The motors can be controlled.

In the preparation pump shown in FIG. 5, the mixing chamber has two Inlet openings 105 and 106 for two subcomponents A and B of the Preparation agent. This arrangement is exemplary. The preparation pump is also suitable for preparation agents consisting of three, four or more Subcomponents exist. Mixing chamber 104 would accordingly have several inlet openings. However, it is also possible for several Subcomponents of the preparation agent together through an inlet opening in the mixing chamber are directed.

In Figure 6 is a second embodiment of an inventive Preparation pump shown with a mixing shaft. The one shown in Figure 6 Preparation pump is essentially in its structure and in its function identical to the embodiment shown in Figure 5. In this respect, the previous description of Figure 5 reference.

The preparation pump in Figure 6 is also a multiple pump with a total eight pairs of gears and eight pump outlets. Opposite the in FIG. 5 embodiment protrudes in an axial extension of the Drive shaft 108 a separate mixing shaft 124 into the mixing chamber 104.

The mixing shaft 124 is through a transmission gear 123 with the drive shaft 108 connected. Thus, the mixing shaft 124 is shared by the motor 117 driven by the drive shaft 108. On the circumference of the mixing shaft 124 are in Several mixing elements 125 are arranged one behind the other. The Mixing elements 125 correspond to several on the pump housing 101 attached mixing elements 126. The mixing elements 126 are stationary.

By rotating the mixing shaft 124, the subcomponents A and B of the Preparation agent, which via the inlet openings 105 and 106 in the Mixing chamber 104 are introduced, mixed. At the end of the Mixing chamber 104 through which components A and B flow is the Pump inlet 103 formed, which is the outlet of the mixing chamber 104th forms. The sub-pumps 122 or the pump inlet 103 thus get a fresh one emulsified preparation. The partial pumps 122 deliver metered Volume flows of the preparation to the pump outlets 114. From However, the preparation passes the pump outlet to one of the Preparation pump downstream wetting device.

In the embodiment shown in Figure 6 is between the mixing shaft 124 and the drive shaft 108, a transmission gear 123 is provided. In order to the mixing shaft 124 can be driven at a higher speed by the drive 117 drive so that an intensive and even mixing of the Partial components of the preparation are carried out prior to delivery.

The mixing elements formed on the mixing shaft can, for example, by Perforated disks, slotted disks or formed by pins.

In those cases where the preparation pump has higher funding Operating speeds, it is also possible that the drive shaft 108 with protrudes into the mixing chamber 104 with its end on the bearing side. Here the end of the drive shaft 108 forms the mixing shaft.

At the end of the drive shaft, the mixing elements shown as Figure 6 can be arranged.

The embodiments shown in Figures 5 to 6 Preparation pump can be used with any wetting device be combined. Especially with the aforementioned pen and Nozzle preparation is a metered delivery of the preparation pump advantageous.
