Definitions
- the invention relates to a device for applying a medium to a thread according to the preamble of claim 1.
- medium means substances or products, for example preparations, bonding agents, dye solutions, hydrophobizing agents or the like.
- the housing of the preparator has a cylindrical passage which is open along a narrow longitudinal strip.
- the implementation serves to accommodate a cylindrical insert with a continuous longitudinal groove.
- the insert is inserted so that the groove lies in the longitudinal opening of the housing so that the thread can be inserted into it. Then it is turned through 180 ° so that the groove is closed with the thread on the outside by the inner wall of the housing.
- the medium is conveyed by a metering pump into a truncated cylindrical recess on the top of the housing, the bottom of which forms the top of the insert.
- the invention is intended to remedy this.
- the invention as characterized in the claims, provides a device for applying a medium to a thread, in which the risk of the medium dripping off and corresponding contamination of the surroundings is prevented. Short-term fluctuations in the feed rate are easily compensated for.
- the medium can be fed under pressure, which ensures thorough impregnation of the thread even at high thread speeds.
- the uniformity of the application, in particular the security against overflow, can be further improved by the special arrangement and design of metering pumps.
- the invention is based on the consideration that an improvement in the application of a medium to a thread can be achieved if it is possible to convey only as much medium to the thread and to distribute it as is required for the intended application. It should also be achieved that media with easily evaporating solvents or highly viscous media can be applied safely.
- the taxidermist 1 shown in FIGS. 1 and 2 consists of a housing 2, which is essentially cuboid and has a cover 3 on one side wall for closing the housing 2, which is pivotably mounted on the housing 2 with a hinge or hinge connection 4 .
- a body 6 made of a porous, surface-active material is inserted, in which the medium to be conveyed is applied to a thread 8.
- the pressure line 5 ends with a mouth 14 on or in the body 6, two mouths 18 are provided in the embodiment according to FIGS. 3-5.
- a line branch 19 is provided after the mouth 14 of the pressure line 5, see FIG. 5, from which two lines 20, 21 extend, which are guided in the walls of the housing 2 up to the mouths 18.
- the orifices 18 are part of hollow screws 23 which are screwed into the housing 2 and form the last part of the lines 20, 21.
- the banjo bolts 23 can be replaced by banjo bolts with a different mouth.
- Fig. 3 it can be seen that the interior of the housing 2 does not need to be completely filled by the body 6. Corresponding recesses are provided in the body 6 for the mouths 18, so that the medium is guided into the interior of the body 6. In the simpler embodiment according to FIGS. 1 and 2, the mouth 14 can of course also be moved inside the body 6.
- the embodiment according to FIG. 4 differs from that according to FIG. 3 only in that the interior is completely filled by the body 6.
- the housing 2 can be opened by moving the cover 3.
- a slot 22 is cut in the body 6 and extends to approximately half the thickness of the body 6.
- the thread can be inserted into the body 6 and into the thread guide 13 through the slot 22, whereupon the housing 1 is closed again with the cover 3.
- the body 6 can consist of different materials. This must be absorbent or have a good surface activity: For this purpose, an integral foam or a body made of an absorbent material, which stores the medium inside, is suitable. However, it is also possible to provide beds of bodies or a foam body.
- FIGS. 6-8 show systems with which a very precise metering of the medium into the preparator 1 is possible.
- a metering pump 10 designed as a double-acting piston pump is used to convey the medium and consists of a cylinder 26 with a piston 27.
- the piston 27 has a piston rod 28 which is moved back and forth by means of a drive.
- the drive 15 is composed of a motor 29 and a gear 30, via which the Piston rod 28 is driven by means of a linear gear (not shown), for example a spindle drive or a rack and pinion drive.
- a line 33, 34 branches off, which is divided into two line parts with a suction valve 35 and a pressure valve 36.
- the two suction valves 35 are connected via a line 37 to a reservoir 38 'for the medium.
- the two pressure valves 36 open into the pressure line 5, which leads to the preparator 1.
- a control device 17 is provided to control the metering pump 10. From this a control line 38 leads to the motor 29 and a further control line 39 to a limit switch 40, which generates the control pulse for reversing the stroke of the piston.
- the control device 17 can also be a programmable processor.
- a constant delivery rate can be continuously fed into the preparator 1, whereby only a slight change in the dosage amount can take place at the reversal points. If a constantly constant delivery rate can be delivered, a metering device with two metering pumps 10, 11 is to be used, as shown in FIGS. 7 and 8.
- the two metering pumps 10, 11 are single-acting pumps which deliver in one stroke direction and suck medium from the reservoir 38 'in the other stroke direction.
- a single drive 15 with a motor 29 is provided, which moves the two piston rods 28 in the opposite direction via a schematically illustrated distribution gear 16 '.
- a solution is further shown in broken lines in which two motors 29 instead of just one motor can be used with a gear 30, as shown in dash-dotted lines for driving the metering pump 10.
- Each of the two metering pumps 10, 11 has a suction valve 35 and a pressure valve 36.
- the same arrangement of the valves as in Fig. 6 can be used.
- the control device 17 is connected via lines 38 to one or both motors 29, while for each metering pump 10, 11 a limit switch 40 is provided with the corresponding control line 39 to the control device 17.
- the two metering pumps 10, 11 can be controlled in their back and forth movement. If the dosing pumps are slightly offset in their cycle, it is possible to maintain a practically constant delivery rate at a reversal point.
- FIG. 8 corresponds to the two-motor arrangement according to FIG. 7, but four / two-way valves 42, 43 are used instead of the check valves used as suction and pressure valves.
- the use of directional valves simplifies the course of the pressure line 5 and the suction line 37.
- the directional valves 42, 43 can be actuated by the control device 17 via control lines 44, 45.
- the reversing of the directional control valves 42, 43 can be carried out in such a way that an unchangeable, constant medium flow is maintained in the pressure line 5.
- the reversal of the metering pumps 10, 11 is controlled in such a way that the reversal takes place at a slightly different time.
- the devices described are characterized by their simplicity. Nevertheless, the delivery of the medium into the body 6 can be metered very precisely.
- the preparator 1 can small, not much larger than a packet of cigarettes. Nevertheless, a perfect all-round application of the medium on the thread 8 is guaranteed. Because of its small dimensions, the housing 2 and thus the preparator 1 can also be easily installed on existing winding machines. It is also possible to use different types of media, and the device can be converted relatively easily for this purpose, since the entire line system is clear and can be easily cleaned.
- the devices described do not require a device for the return of medium, since only as much preparation agent is conveyed as is applied to the thread.
- the device thus represents a closed fluid system; it avoids contamination of parts of the winding machine and saves on preparation agents. Nevertheless, the metering device can be switched off over a longer period of time without the feared drying out of aqueous media without emptying the system.
