Technical Field
The present invention relates to a thread supply for supplying thread to a textile machine.
Background
The thread supply is provided with a housing and a storage device, wherein the thread is drawn from the storage device through the textile machine. Such a supply is also referred to as a memory-supply.
A thread supply device for a textile machine is known from EP 2065496. The thread feeding device comprises a fixed storage body and a housing arm extending along the storage body. A line brake having a brake body is arranged at the housing arm. The braking body is pressed against the extraction end of the storage body by means of a permanent magnet assembly of an adjusting mechanism. An adjusting device for adjusting the braking effect is provided. The relative axial position of the permanent magnet assembly is variable by the adjustment mechanism either stepwise by a threaded fastening means or by a quick adjustment mechanism. For changing the brake body, the quick adjustment mechanism is activated in that the operating threaded fastener is pulled out manually with the components of the adjustment mechanism against the force of the spring. This requires manually fixing the threaded fastener during replacement of the braking body. Even in the case of further maintenance of the feeder, for example in the case of cleaning, the threaded fastener must be fixed manually. The space obtained by the pulling-out can be arranged in the adjusting device, whereby it requires a certain axial length.
EP1262436B1 describes a fastening device which can be disengaged quickly for a brake unit for a weft feeder. The brake unit has a support ring with a fastening foot, which is fastened to a support slide so as to be displaceable. The support slide is axially movable with respect to the cylinder of the feeding device. The fastening feet of the support ring and the support slide are fastened to one another by means of magnetic fastening elements. In one embodiment, the support ring is allowed to rotate relative to the support slider about an axis at right angles to the joint plane.
The support ring can be completely removed from the support slider by overcoming the magnetic force of the fixing element. During the connection of the support ring to the support slide, a tilting movement of the support ring is permitted in the illustrated alternative.
Disclosure of Invention
The object of the invention is to develop a storage and supply device with a release device which allows a simpler release of the braking device and better accessibility to the braking body and the storage device.
A thread supply device according to the present invention for supplying thread to a textile machine is provided with a housing and a reservoir device from which thread is drawn through the textile machine. The memory device comprises a fixed, drum-shaped memory body with a body axis. The cage of the housing extends along the storage body. The thread supply is provided at the holder with a braking device for adjusting the thread tension of the thread, which braking device is arranged behind the storage body in the course of the thread. The braking device has a braking body, an adjusting device and a release device. The adjusting device comprises at least one adjusting element which is arranged in an adjustable manner in relation to the housing in the direction of the body axis of the storage body. Since the body axis of the storage body is substantially coordinated with the axis of the thread supply, for example by the axis of the drive shaft, the adjustment element can be axially adjusted with respect to the housing. That is to say that the adjusting element is arranged axially adjustable.
The braking body can be pressed against a clamping surface at the withdrawal end of the storage body by means of the adjusting element in the clamping position. The decoupling device comprises a carrier element which is connected at least to the adjusting element and which is arranged movably relative to the housing.
The carrier element carries the adjusting device and is arranged rotatably about a carrier axis. The carrier shaft is arranged in a carrier section of the cage and runs perpendicular to a cage axis, which extends parallel to the body axis through the cage of the housing, and perpendicular to a connecting line between the body axis and the cage axis.
The adjustment device of the braking device is rotated out of the body axis of the storage body when the carrier element is rotated about the carrier axis. The space thus released below the brake body allows simple replacement of the wearing parts of the brake body. Furthermore, the rotatability out of the body axis by the adjusting device improves the accessibility to the storage device after the brake body is removed. The improved accessibility also enables the memory device to be displaced by a defined amount in the direction of the body axis, for example for cleaning purposes.
In one embodiment, the carrier shaft is arranged in the region of an end of the brake body, which faces away from the storage body. This enables a simple folding of the adjustment device.
In one embodiment, the disengagement device comprises a locking element by means of which the carrier element can be locked in at least one locking position. In the locked position, the locking element protrudes into a recess in the carrier section of the cage.
In one embodiment, the locking element comprises a spring and an operating pin. The spring serves to press the locking element into the locking opening. The release pin is arranged on a locking spring, wherein the locking spring is compressed when the actuating pin is actuated.
In one embodiment, one of the locking positions is a clamping position of the adjustment device.
In one embodiment, one of the locking positions is a disengaged position of the adjustment device.
In one embodiment, the disengagement means comprise an elastic element which is supported on the carrier section of the holder and exerts an elastic force on the carrier element with respect to the direction of rotation of the carrier element about the carrier axis when the adjustment means are disengaged.
In one embodiment, the carrier section of the cage is designed as a removable cage part. This enables adjustment of the brake device and replacement of the release device and thus replacement of the brake.
The thread feeder configuration according to the invention is used for feeding thread to a knitting machine. The knitting machine is a circular knitting machine or a flat knitting machine or a knitting machine or the like. Alternatively, the thread feeder according to the invention is configured for feeding weft thread to a weaving machine (webmaschene).
