Definitions

  • the present invention relates to a device for oiling a running yarn with a housing, with a metering pump arranged in the housing and with a yarn guide device with an oil transfer element mounted in the yarn guide device, the oil transfer element being connected to the oil connection through an oil delivery channel via the metering pump.
  • Devices of this type are known from the prior art, for example disclosed in CN 208 545 538 U a device for oiling a running yarn with a metering pump which is designed as a gear pump and is driven by an electric motor.
  • the oil is transferred via a supply line from the metering pump to a sponge inserted in a yarn guide groove, through which the oil is applied to the yarn.
  • a heater is provided to warm the oil.
  • the CN 209 636 478 U the use of a heating plate to heat the oil is known.
  • a disadvantage of the known designs is that due to the pressure conditions in the oil distribution, an overflow of oil from the metering pump to the yarn guide device occurs when the device is at a standstill.
  • the CN 207 452 340 U tried to remedy this disadvantage by a device for oiling a running yarn with an inserted yarn guide device which has a protective cover. This can prevent oil from escaping from the device, but it does not prevent oil from running into the yarn guide device.
  • Another disadvantage is that the amount of oil absorbed by the yarn is determined by empirical adjustments of the oil pump and cannot be adapted to circumstances such as slowed yarn running.
  • the object of the present invention is therefore to propose a device for oiling a running yarn or thread, which prevents unwanted oil leakage and enables precise metering of the amount of oil.
  • What is proposed is a device for oiling a running yarn with a control and with a housing and with an oil connection provided in the housing and with a metering pump arranged in the housing and with a yarn guide device with an oil transfer element mounted in the yarn guide device, the oil transfer element passing through an oil delivery channel via the Dosing pump is connected to the oil connection.
  • a closure element and a flow sensor are provided in the oil delivery channel.
  • the oil delivery channel has a first section from the oil connection to the metering pump, a second section from the metering pump to the closure element and a third section from the closure element to the oil transfer element, the flow sensor being provided in the second section.
  • the device is supplied with oil from a storage container which is connected to the oil connection via a line.
  • a hose connection has proven to be useful, making it easy to change the type of oil.
  • a cleaning agent for maintenance and cleaning of the device can also be introduced via the oil connection.
  • the yarn is usually wetted with an oil quantity of 0.4 ml/kilometer to 10 ml/kilometer.
  • the amount of oil depends on the type of yarn and the intended use of the yarn.
  • the metering pump output is between 0.1 ml/min and 30 ml/min.
  • the metering pump delivers the oil in the required amount to the oil transfer element which is embedded in the yarn guide device.
  • the yarn running in the yarn guide device comes into contact with the oil transfer element, which results in a transfer of oil to the yarn.
  • the oil delivery channel built into the housing from the oil connection to the yarn transfer element is designed in three sections. The individual sections can be designed as bores or channels in the housing or as pipes. Bores and channels, which Completely surrounded by the housing are preferable to screwed or otherwise connected pipes, as there is no possibility of leakage.
  • the first section of the oil delivery channel leads from the oil connection to the metering pump.
  • the oil connection is advantageously designed as an internal thread or a commercially available coupling for hose lines.
  • the metering pump can be integrated into the housing of the device, so that a housing of the metering pump is an integral part of the housing of the device.
  • the second section of the oil delivery channel leads from the metering pump to the closure element.
  • the flow sensor is installed in this section. The flow sensor detects the amount of oil delivered by the metering pump to the oil transfer element.
  • the design of the flow sensor is, for example, an ultrasonic or Coriolis mass flow meter.
  • a calorimetric flow meter has proven to be the preferred version, as it can be used to measure even the smallest amounts of oil pumped.
  • the closure element following the second section has the advantage that no oil can reach the oil transfer element if, for example, no yarn is guided through the yarn guide device or the yarn does not need to be oiled.
  • the closure element prevents oil from dripping through the oil transfer element when it is at a standstill and contaminating the yarn guide device or its surroundings. In addition, cleaning of the yarn guide device or the oil transfer element before restarting the device can be avoided.
  • the third section of the oil delivery channel leads from the closure element to the oil transfer element.
  • the oil transfer element is embedded in the yarn guide device and is designed, for example, as a sponge or other type of porous element.
  • the oil delivered to the oil transfer element through the third section of the oil delivery channel penetrates the oil transfer element and is passed through the Touching the oil transfer element with the yarn running past it transfers it to the yarn.
  • the closure element is a shut-off valve with an electromagnetic drive.
  • Shut-off valves have the advantage that they are of simple construction and can be installed in the housing of the device in order to completely close the oil delivery channel.
  • the electromagnetic drive can be used to switch the shut-off valve in such a way that it is closed in the de-energized state. This means that when the system is at a standstill, there is no energy requirement to keep the shut-off valve closed and the shut-off valve closes automatically even in the event of a power failure.
  • the third section of the oil delivery channel is at least partially designed as a heating coil.
  • the oil is passed through a heating coil, which can be designed as a single turn or as multiple turns in the form of a spiral.
  • the heating coil the oil is heated to a higher temperature than when stored. A certain amount of heating energy is introduced into the heating coil. The amount of energy is kept constant by the control system, which is tailored to the type of oil used and the yarn to be oiled.
  • the heating coil is preferably provided with a temperature difference measurement. An input temperature measurement is provided at the entrance of the heating coil and an output temperature measurement is provided at the output of the heating coil. With the help of the measured temperatures, the supply of heating energy to the heating coil is regulated. This has the advantage that it is independent of the operating load of the device An ideal viscosity of the oil can always be set. This leads to an even and consistent wetting of the yarn over the entire length of the yarn.
  • the yarn guide device is attached to an outside of the housing and open to the surroundings of the device. Attaching the yarn guide device to an outside of the housing leads to easy access and thus easy threading of the yarn into the yarn guide device.
  • the yarn guiding device can consist of several components; for example, the yarn can be guided by separate guide plates at the upper and lower ends of the housing. Such guide plates are characterized by a guide slot which has a side opening, which means that the yarn, once threaded, cannot jump out of the guide on its own.
  • the two guide plates can be connected to a middle part of the yarn guide device which is arranged between them and contains a guide groove.
  • the yarn guide device is held in the housing so that it can be moved linearly. This means that even if the yarn guide device is replaced, for example due to a change in the material of the yarn, easy disassembly can be carried out.
  • a longitudinal groove corresponding to the yarn guide device is provided.
  • the yarn guide device can be inserted within this longitudinal groove and held by pins, screws or clips.
  • the yarn guiding device is preferably connected to the housing via a dovetail guide. This makes it possible to achieve a precise alignment of the yarn guide to an exit of the oil from the third section of the oil delivery channel.
  • a clamping guide in which the yarn guide device is held in a defined position in the housing, for example by elastic plastic elements.
  • An oil transfer element is embedded in the yarn guide device, which is usually made as a sponge or made of a porous material, so that the oil passes through the oil transfer element the yarn can reach.
  • the oil transfer element is advantageously detachably connected to the yarn guide device.
  • the oil transfer element is a wearing part and must therefore be replaced at specified intervals. Due to the detachable connection between the oil transfer element and the yarn guide device, only the oil transfer element can be replaced and the yarn guide device remains unaffected.
  • the control is advantageously attached to the housing or integrated into the housing.
  • the control or the housing is preferably provided with a visualization for displaying operating states, measured values such as temperature, flow, consumption, etc. and a keypad for operating the device and entering control parameters.
  • Direct visualization can be implemented with a touchscreen, whereby the keypad can be integrated into this touchscreen and does not have to be present separately.
  • simple visualization using simple colored light displays and a separate keypad can also be provided.
  • the data of the measurements and operating states of the device can also be transmitted to a higher-level controller via wired or wireless communication.
  • a corresponding interface between the control of the device and a higher-level control makes it possible to remotely control the device for oiling a running yarn.
  • the visualization provides a display of at least one of the following information: an amount of oil; an oil temperature; oil consumption; an operating state; an operating mode; an operating period; an operating manual.
  • Operating instructions can, for example, contain information about necessary maintenance or the replacement of wearing parts.
  • Static values can also be output via the visualization.
  • the oil is then pumped via a second section of the oil delivery channel through a flow sensor to a closure element and via a third section of the oil delivery channel to the yarn guide device, with the control closing the oil delivery channel by actuating the closure element when the metering pump is at a standstill.
  • By closing the oil delivery channel it is ensured that when the machine is at a standstill or when the device for oiling a running yarn is not in use, no oil drips out of the oil transfer element and contaminates the yarn guide device.
  • a large amount of oil can flow out of the oil transfer element even after the metering pump is switched off and contaminate machine elements or yarn packages arranged below the device.
  • a heating coil with an input temperature measurement and an output temperature measurement is provided and the control regulates a temperature of the oil at an output of the heating coil.
