Definitions
- the present invention relates to a method for rotating a sleeve for bobbins of a textile machine, the sleeve being removed from a sleeve magazine oriented in a first direction, rotated essentially 90 ° transversely to its sleeve axis in a second direction and in the second Direction is transported with a transport device.
- the invention further relates to a device for rotating a sleeve for bobbins of a textile machine, with a removal device for removing a sleeve from a sleeve magazine in a first direction, and with a transport device in order to transport the sleeve further in a second direction.
- Modern textile machines for the production or rewinding of yarn generally have a large number of possibly independent winding stations for winding the yarn.
- the yarn is wound on bobbins, the core of which forms a sleeve made of cardboard, for example.
- bobbins the core of which forms a sleeve made of cardboard, for example.
- the winding units must be supplied with sleeves in order to continue the winding process.
- this exchange takes place automatically, with large numbers of cores being held in so-called core magazines.
- One problem that arises in this connection is that the cores sometimes have to be transported to the winding units in a certain orientation. For this purpose, methods and devices are required with which the orientation of the sleeves can be influenced.
- GB 1091207 A describes a device which has two conveyor belts spaced apart from one another. Conical sleeves straighten up in the gap between the belts and lie in a horizontal position at the end of the conveyor belts, the sleeves all having the same orientation in the horizontal position.
- the decisive disadvantage of this device is that it can only be used for conical sleeves.
- the sleeve is removed from a sleeve magazine oriented in a first direction, then rotated essentially 90 ° transversely to its sleeve axis in a second direction and in the second direction with a transport device transported on.
- the method is characterized in that a first side of the sleeve contacts a transport device moved transversely to the first direction in the second direction. The transport device moves this first side transversely to the sleeve axis.
- a second side of the sleeve is not moved, or at least slower, transversely to the sleeve axis relative to the first side, so that the sleeve rotates transversely to the sleeve axis.
- Uneven acceleration of the two sides of the sleeve should be used here to generate a torque that leads to a rotation of the sleeve.
- the direction of rotation depends on the side of the sleeve that comes to rest on the transport device.
- sleeve axis is here and in the following the longitudinal axis of the sleeve is meant, that is the axis which corresponds to the direction of the greatest extension of the sleeve.
- the method according to the invention allows the sleeve to be rotated in the desired direction with comparatively little effort.
- a transport device is usually necessary regardless of a method for rotating the sleeves in order to transport the sleeves to the winding stations.
- the method can also be used for non-conical sleeves. As long as it is possible to first place a certain side of the sleeve on the transport device, the shape of the sleeve does not matter.
- the first and second directions are preferably perpendicular to one another.
- the first and the second direction in particular form a plane that is parallel to a surface on which the textile machine is located.
- the transport device can be, for example, a conveyor belt, in particular a circulating endless conveyor belt. It is conceivable that the transport device is in operation at the moment when the first side of the sleeve comes into contact with it. Alternatively, the transport device can also come to a standstill first and only be put into operation after contacting the first side of the sleeve.
- the second side of the sleeve is not moved, or at least slower, transversely to the sleeve axis, relative to the first side.
- the second side of the sleeve can be held back by the friction on a surface on which the second side initially lies.
- the sleeve first contacts the transport device with one of its ends. This creates a particularly high torque due to the maximum length of the lever arm and the sleeve is rotated quickly or with little space requirement.
- the ends of the sleeve are, in particular, areas which directly adjoin the generally circular, front-side boundary surfaces of the sleeve.
- the sleeve comes to rest on the transport direction. As a result, the sleeve can be transported further from the transport device to a corresponding winding unit. As already described, the sleeve does not come to rest completely on the transport device, in particular until the rotation has been completed. For the rotation of the sleeve, it is of crucial importance that one side of the sleeve first comes to rest on the transport device. As a rule, the side of the sleeve that comes first to lie on the transport device is at the front after the rotation. The front should refer to the order of the sleeve areas during transport through the transport device. During the rotation, the sleeve axis of the sleeve preferably remains essentially parallel to the previously mentioned surface on which the textile machine is standing.
- the sleeve it is conceivable for the sleeve to be pushed over the transport device, the second side of the sleeve first contacting the transport device, but initially not resting on it. In this case, too, the sleeve rotates such that the first side of the sleeve is at the front after the rotation.
- the second side of the sleeve is initially held back by a component and only reaches the transport device after the sleeve has started to rotate.
- the component can be a retainer or also a component of a removal device, such as a holder or sleeve mandrel. It is also advantageous for the method if the second side of the sleeve comes to rest on a second transport device and is transported there at a speed and / or direction which differs from the first transport device.
- the rotation of the sleeve can also take place while the entire sleeve is already being transported in the direction of the winding stations by the transport devices. Time can thus be saved when transporting the sleeve.
- the sleeve can, for example, be placed with one of its sides on two spaced apart conveyor belts.
- the conveyor belts can move at different speeds, causing the sleeve to rotate.
- the direction of rotation is determined by the difference in speed of the conveyor belts or transport devices. For example, the first side of the sleeve is rotated forward at a higher speed of the first transport device. If the transport devices move in different directions, the sleeve can be rotated even in a very small space.
- the first side of the sleeve after the sleeve has been removed from the sleeve magazine, is pushed over the second transport device and thereby initially comes into contact with this second transport device, but does not come to rest on it. It is also conceivable that the second side of the sleeve is pushed over the first transport device and that it initially comes into contact with it but does not come to rest on it. After the rotation, the sleeve is preferably located completely on one of the transport devices.
- the rotation of the sleeve or the movement of the sleeve onto one of the transport devices can additionally be caused or accelerated by a retainer in addition to the different movement speeds or directions of the transport devices.
- the retainer is preferably arranged between the transport devices. It is of great advantage if the sleeve is pushed onto the first and / or second transport device by a holder of the sleeve magazine.
- the direct transition of the sleeve from the sleeve magazine to the transport device (s) allows space and time-saving transportation of the sleeves in the desired orientation.
- the mechanical implementation of the method is also kept as simple as possible and thus inexpensive and error-resistant.
- the direction in which the sleeve is rotated can depend, for example, on how far the sleeve is pushed.
- the sliding path thus determines in particular which side of the sleeve comes to rest on the transport device.
- the device according to the invention for rotating a sleeve for bobbins of a textile machine comprises a removal device for removing a sleeve from a sleeve magazine in a first direction.
- the device has a transport device in order to further transport the sleeve in a second direction. It is proposed that the removal device move a first side of the sleeve from the sleeve magazine onto a first transport device, in particular a first conveyor belt, which is moved transversely to the first direction, the first transport device moving transversely to the sleeve axis.
- a retainer or a second transport device in particular a second conveyor belt, is provided, with which the second side of the sleeve is not moved, or at least slower, transversely to the sleeve axis relative to the first side, so that the sleeve rotates transversely to the sleeve axis.
- the device according to the invention is particularly suitable for carrying out the method described above.
- the advantages for the device are similar to those for the method.
- the device offers a comparatively simple possibility of sleeves in a desired orientation bring to. Sleeves of almost any shape can be processed.
- a transport device is generally necessary regardless of the rotation of the sleeve in order to transport the sleeve to a corresponding winding position.
- the transport device is used simultaneously for the rotation of the sleeve, which is particularly space and time-saving.
- the sleeve axis is to be understood to mean the longitudinal axis of the sleeve, that is to say the axis which corresponds to the direction of the greatest expansion of the sleeve.
- the first and the second direction are preferably perpendicular to one another and form a plane which is parallel to a surface on which the textile machine is located.
- the device causes the sleeve to rotate essentially by 90 °.
- the transport device or the conveyor belt is, for example, a continuous endless conveyor belt.
- the transport device or the transport devices can extend essentially over an entire length of the textile machine. It is conceivable to subdivide the transport device (s) into several independent sections, with which, for example, the rotation of the sleeve and the further transport can be carried out independently of one another.
- the removal device comprises a slide with which the sleeve is pushed onto the transport device.
- the slide allows the sleeve to be transferred from the removal device to the transport device in a simple and controlled manner.
- the sleeve can, for example, sit on a holder or sleeve mandrel of the removal device or the sleeve magazine, from which the slide pushes it onto the transport device (s).
- the slide can, for example, be arranged on an upper side of the textile machine and / or the sleeve magazine.
- the slide is designed to carry out a displacement of variable length of the sliding path.
- the direction in which the sleeve is rotated can depend on the length of the sliding path, for example by the length of the sliding path deciding which side of the sleeve comes to rest on the transport device first.
- the retainer is a holder of the sleeve magazine.
- An additional retainer may possibly be saved in this way.
- the device must be designed in such a way that the sleeve contacts at least temporarily both the holder and the transport device. In the course of the rotation of the sleeve, the contact with the holder is then separated, for example.
- the holder can in particular be designed as a sleeve mandrel.
- the holder of the sleeve magazine serves as a retainer, but that an additional independent retainer is also provided.
- the direction of rotation of the sleeve then depends, for example, on whether the sleeve is retained by the holder or by the additional retainer.
- the two retainers are in particular on different sides of the transport device.
- the retainer is a rotating plate.
- rotating plate is meant a plate-shaped component that causes rotation as an obstacle for the sleeve.
- the rotating plate represents a particularly material-saving version of a retainer.
- the height of the rotating plate preferably corresponds essentially to the diameter of the sleeve.
- the rotary plate can be made of metal, for example, which makes it particularly robust and durable.
- the surface of the rotating plate is in particular perpendicular to the second direction.
- the rotating plate has a stop and a storage surface for one side of the sleeve.
- the storage surface can be designed with increased roughness in order to prevent undesired movement of the sleeve.
- the stop serves to actually hold back and turn the sleeve.
- the height of the stop preferably corresponds essentially to the diameter of the sleeve.
- the storage surface can be part of an upper side of the textile machine, for example.
- the stop and storage area preferably adjoin the transport device directly.
- the stop and / or the storage surface is arranged inclined to the first and / or second direction. Inclined here means that the stop and / or the storage surface is neither perpendicular nor parallel to the first and / or second direction. This enables improved control of the movement of the sleeve.
- the rotation of the sleeve can be accelerated by the inclination of the stop, and the inclination of the storage surface can force the sleeve to move in the direction of the transport device.
- the storage surface can in particular be designed as an inclined plane on which the sleeve slides / rolls in the direction of the transport device.
- the device has both a first and a second transport device and at least one retainer.
- the rotation of the sleeve can be caused by the difference in speed or by a different direction of movement of the two transport devices.
- An additional retainer can help to complete the rotation of the sleeve faster and in a more controlled manner.
- the retainer can force the sleeve onto one of the two transport devices, on which it is then transported to a corresponding winding unit.
- the retainer is preferably arranged between the transport devices. It is also conceivable for the device to have a plurality of retainers and a plurality of transport devices.
- the device can have a sensor for determining the sleeve orientation, it being possible to use a measurement result from the sensor to decide in which direction the sleeve should be rotated by the device.
