Operation means 8 are provided corresponding to reception parts 5 and 6, respectively. The operation means is configured so that the front end 4 of the cup supported by the holding means 7 is not captured by the operation means during the operation of the operating means 8, and a cup base part 3 positioned in a receiving part 5 is captured by the operation means during the operation of the operating means 8 so that the cup 2 or the wound pipe 20 is moved in a horizontal direction and thereby the cup 2 or the wound pipe 20 drops downward with the cup base part 3 in front.

Description

  The present invention is provided horizontally in any orientation with one cup end formed as a cup base with a large diameter and one cup end formed as a cup tip with a small diameter. An apparatus formed to turn a cup and a winding tube so that the cup or the winding tube falls downward with the cup base first, and one of the cup ends. One receiving part with an intermediate chamber is provided for receiving one, in which case both receiving parts are located facing each other and are arranged symmetrically with respect to one vertical plane Each of the intermediate chambers is sized or formed such that the tip of the cup passes through the intermediate chamber and the base of the cup does not pass through the intermediate chamber. The holding means is arranged so as to support the tip of one cup or the cup of the winding tube and thus to prevent falling. In this case, the cup or the cup base of the winding tube relates to a device which is located in a receiving part located oppositely.

  Spinning cups are produced on a ring spinning machine and have a relatively small yarn volume. The spinning cup is rewound in a winding machine into a twill package having a significantly larger yarn volume for later processing. The cup is removed from the ring spinning machine and transported and stored, for example, in a cup container. Within these cup containers, the cups are placed unordered and must be individualized again for further processing. Correspondingly, the empty winding tube, which has been fed out in the winder, must be transported to the ring spinning machine again in such a container, and must be individually separated accordingly. For further automated processing, the cup in the rewinder or the winding tube in the ring spinning machine is automatically individualized and positioned, for example, on the transport tray with the cup tip facing up. The cup base is in this case held by the insertion mandrel of the transport tray. It is absolutely necessary to position the cup tip facing up for further processing.

  The cup supply station disclosed in Patent Document 1 separates cups that are present randomly, directs the cup tip upward in the vertical direction, and delivers the cup at a predetermined timing to the cup conveying means of the winder. The cup carousel, which operates on the basis of the oscillating motion, is followed by a cup chute, a cup feeder and a cup direction changer. This cup direction changer is disposed above the cup supply cylinder, and this cup supply cylinder supplies the cup to the cup conveying means. The cup changer is in this case formed such that the cup changer can pivot the cup from a horizontal position to a vertical position and that both directions of rotation are possible. The necessary rotation direction is determined by a sensor that detects one end of the next cup to be supplied and distinguishes the cup tip from the cup base.

  A variety of comparable cup turning devices having separate sensor devices for detecting the orientation of the cup or winding and a mechanism for turning the cup or winding in relation to the detected orientation are known in the prior art. Various configurations are known. These known configurations are based on the need to perform a wide variety of movements, and not only the mechanism, but also the control devices and actuators are correspondingly complex or expensive.

  However, the prior art also knows devices for processing cups and / or empty tubes provided in any orientation, without the need for a sensor device for detecting the orientation.

  Patent Document 2 discloses a device for changing the direction of an empty winding tube provided horizontally. This device has one receiving part with a winding tube base and an intermediate chamber for the winding tube tip, in which case the winding tube tip passes through the receiving part and the winding tube base initially It is formed so as to be held in the receiving part. The winding tube first drops with the tip of the winding tube first. The tube tip then falls towards one of the two transverse webs. Then, the winding tube is turned by the lateral web, and the winding tube finally falls in the vertical direction with the winding tube base first. However, it has to be said that the position of the transverse web is difficult, so that the particular winding type is always turned as desired. This is because the drop characteristics of the winding tube are strongly dependent on its weight distribution. For wound tubes or cups, it is almost impossible to reliably predict the drop characteristics. This is because the exact distribution of the yarn, and hence the weight distribution, clearly changes even with equal windings and equal yarn amounts in the winding. Such known devices are therefore not suitable for cups.

  U.S. Patent No. 6,057,077 discloses a device for directing a cup having one receptacle each with a cup base and an intermediate chamber for the cup tip. In this case, the cup tip passes through the intermediate chamber, and the cup base does not pass through the intermediate chamber. As a result, the cup falls with the tip of the cup first. The surface with which the falling cup collides is positioned so that the cup is introduced into a horizontal position. In other words, in this case, another treatment is required to bring the cup to a position in which the tip of the cup is directed upward.

  Patent Document 4 discloses an apparatus for classifying or selecting a winding tube. In this case, the winding tube is positioned on the support base. There are also two ejectors that are arranged in the region of both ends of the winding tube and can be operated simultaneously. The height of the support base is such that the winding tube base portion of the corresponding winding tube enters the movement path of the ejector directed to the winding tube base portion, whereas the winding tube tip is the movement path of the ejector. It is dimensioned to be located below. During operation of the ejector, the winding tube base is pushed out of its support so that the winding tube first falls into the drop cylinder. This device is only suitable for winding tubes. When the yarn is wound around the winding tube, the yarn body in the winding tube is prevented from moving by the support base on the leading end side of the winding tube, or the thread body is moved beyond the support base. This may cause damage to the yarn. Furthermore, there is a possibility that the ejector on the leading end side of the winding tube may catch the thread body. Further, the interval between the support bases from the ejector is determined by the conicity of the winding tube, and the winding tube base cannot be captured, so it cannot be arbitrarily increased.

  The apparatus disclosed in Patent Document 5 is configured to change the direction of a cup and a winding tube provided in an arbitrary orientation so that the cup or the winding tube falls in a vertical direction with the cup base first. Has been. Only the direction of the cup is clearly described. However, on the basis of the mode of action, it is assumed that the device can be used in a wound tube as well. This known device has one receiving part with an intermediate chamber for both cup ends. Both receiving parts are located facing each other and are arranged and formed symmetrically with respect to the vertical plane. The receiving part is formed from two discs each having the shape of a circular section. These discs are rotatably supported and have elastic linings on their peripheral surfaces. The intermediate chamber is formed by the spacing between both discs and is dimensioned so that the cup tip passes through the intermediate chamber and the cup base does not pass through the intermediate chamber. This known device has holding means formed as support vanes, these holding means being rotatably supported and held by a spiral spring. And the holding means are respectively arranged under the receiving part, and this holding means is configured to support the cup or the cup tip of the winding tube located in the receiving part located on the opposite side of the cup base. Yes.

  The disk is rotated so that the cup falls downwards with its cup base first. The cup base located between the disks is drawn between the disks. The elastic lining is deflected at this time. The cup base is pressed against the support vanes by the disk. As a result, the support blades rotate downward against the force of the spiral spring. In the specified position, the support vanes are captured by pins fixed to one of the receiving discs. As a result, the supporting blade is further rotated downward until the cup base finally falls in the vertical direction.

  The device of Patent Document 5 can only be operated with limited timing output. This is because the disc needs to clamp the cup base and cannot rotate at any speed. Furthermore, such a clamp causes the elastic lining to wear.

  Therefore, an object of the present invention is to improve the apparatus disclosed in Patent Document 5 and to enable a direction change of a cup and a winding tube provided in an arbitrary orientation with high timing output and slight wear. Is to provide.

  According to the present invention, this problem is solved by the configuration described in the characterizing portion of claim 1. Preferred embodiments of the invention are described in the dependent claims.

  That is, in order to solve the above-mentioned problem, in the configuration of the present invention, in the apparatus described at the beginning, the cup supported by the cup tip by the holding means or the winding tube supported by the cup tip in the horizontal direction on the holding means. The holding body is configured to be movable at or inside thereof, and is provided with operating means disposed corresponding to the receiving portion, and the operating means is a cup supported by the holding means. The tip is not captured by the operating means when operating the operating means, and the cup base located in the receiving portion is captured by the operating means when operating the operating means, and the cup or the winding tube is moved in the horizontal direction. The cup or the winding tube is configured to fall downward with the cup base first.

  The device according to the invention is suitable for both cups and tubes. In accordance with the present invention, the device is configured so that the cup or winding tube can be moved horizontally and thereby the cup base can fall downward. Therefore, no clamping of the cup base is necessary. This can greatly increase the cycle time and reduce wear. The required operating means can be simply constructed and can be actuated, for example, by a pneumatic or electric drive.

  The operating means of both receiving parts can be operated simultaneously. Depending on the construction of the device, the cup or winding tube is always positioned so that the cup base is located in the receiving part and the cup tip is located on the holding means. The operating means can have a separate capture area in order to reliably capture the cup base. Based on the above-described arrangement, there is no possibility that the winding tube tip is inadvertently captured.

  The thread body in the wound tube does not impair the movement of the wound tube in the horizontal direction. This is because the cup occupies a somewhat inclined position, with the cup base located in one receiving part and the winding tip positioned on one holding means. Based on this inclined position, only the edge of the cup tip slides over the holding means. The thread body does not contact the holding means.

  The receiving part is preferably formed as a hopper-shaped contour. If comprised in this way, the guidance of a cup or a winding tube at the time of supply to a direction change apparatus will be improved. The cup or winding tube can be fed, for example, via a conveyor belt. A flap may be disposed above the hopper-shaped contour, and the cup falls into the hopper opening when the flap is operated.

  According to a preferred aspect of the present invention, the width of the intermediate chamber is adjustable. When configured in this way, the receiving part can be adapted to a wide variety of winding tube diameters. The requirements for the accuracy with which the intermediate chamber must be adjusted are not particularly large. This is because the intermediate chamber simply needs to be larger than the diameter of the cup tip and smaller than the diameter of the cup base. That is, the labor or cost according to the present invention is small.

  In another aspect of the invention, the spacing between the receivers can be adjusted in the axial direction of the cup. Such a configuration allows adaptation to a wide variety of cup lengths.

  Each of the receptacles may have a limiting means for limiting the movement of the cup in the axial direction. This facilitates proper positioning of the cup and prevents inconvenient movement of the cup or the winding tube in the axial direction before the operation means is actuated.

  In a preferred embodiment of the invention, each hopper-shaped contour is formed by two hopper sheet metal.

  According to another aspect of the invention, the operating means is configured to form a second hopper-shaped contour with one hopper metal sheet in a state in which the operating means is operated. The second hopper-shaped contour portion is necessarily narrower than the hopper-shaped contour portion made of both hopper metal thin plates and is disposed at a high position. And the drop height of the cup or tube is reduced and the guidance is improved.

  In a preferred aspect of the invention, the second hopper-shaped contour cannot be passed by either the cup base or the cup tip. In this way, the cup or tube is initially held within the second hopper-shaped contour. Due to the inactivation of the operating means, the turning process can be continued in a limited state. In this case, the cup base is held in a hopper-shaped contour made of both hopper metal sheets, and the tip of the cup falls to the holding means.

  According to another aspect of the invention, one of the hopper metal sheets reaches the holding means. This improves the guidance of the cup tip falling on the holding means through the intermediate chamber between the hopper metal sheets.

  If one of the hopper metal sheets is movable, the intermediate chamber between the hopper metal sheets can be easily adjusted. It is not necessary that both hopper sheet metals are movable. The immovable hopper sheet metal may be mounted so that it always reaches the holding means.

  In another preferred embodiment of the device according to the invention, one identical molding member is arranged corresponding to the hopper-shaped contour. The hopper metal thin plate may be fixed to the molded member, and the molded member may surround at least a part of the holding means. The molded member is preferably formed as a guide for the operating means.

  By using the same molded member, an advantage in manufacturing the direction changing device can be obtained. The number of the same members increases. This facilitates the production and inventory management of the molded part.

It is a perspective view which shows the shaping | molding member of the apparatus by this invention. It is a side view which shows the shaping | molding member shown in FIG. 10 to which the hopper metal thin plate was attached.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a device 1 according to the invention for turning a cup 2 and a winding tube 20. The function of this device 1 will be described below for the cup 2. However, this function is given to the winding tube 20 in the same manner. The winding tube 20 which is covered for the most part by the winding of the cup 2 is indicated by a broken line. The device 1 has two receptacles 5, 6 which are located opposite each other for the cup end, in which case the receptacles 5, 6 are in one vertical plane between the receptacles 5, 6. In contrast, they are arranged symmetrically and formed. Each of the receiving portions 5 and 6 is formed as a hopper-shaped contour portion 11, and the contour portion 11 is formed by two hopper metal thin plates 12 and 13. The hopper metal thin plates 12 and 13 are attached to one molding member 15.

  In FIG. 10, only the molding member 15 is shown. The forming member 15 has two insertion portions 18 for the hopper metal thin plates 12 and 13. FIG. 11 is a side view of the forming member 15 to which the hopper metal thin plates 12 and 13 are attached. In this case, the hopper metal thin plate 13 reaches the bottom 19 of the molded member 15. Since the hopper metal sheet 12 is movable, the intermediate chamber 9 at the end of the hopper-shaped contour 11 can be adjusted. Thereby, the intermediate chamber 9 can be adjusted so that the cup tip 4 of the selected cup 2 passes through the intermediate chamber 9 and the cup base 3 of the cup 2 does not pass through the intermediate chamber 9. The cup tip 4 passing through the intermediate chamber 9 is guided by a hopper metal thin plate 13 extending to the bottom 19 of the molding member 15, and finally, a recess 7 formed from the hopper metal thin plate 13 and the bottom 19 of the molding member 15. Held in.

  Furthermore, the molding member 15 has a guide 17 for operating means which serves to push the cup base 3 out of the receiving part. The operating means is formed as a slide element 8 in the illustrated embodiment. The operation of the slide element 8 can be performed, for example, pneumatically or electromechanically. However, the movement of the cup 2 can also be carried out by means of suitable swiveling elements. During the operation of the slide element 8 or the running extrusion, the slide element 8 and the hopper metal thin plate 12 form a second narrow hopper-shaped contour portion 14. The element 16 arranged on the slide element 8 and formed as part of the molding member 15 serves as an additional guide when a new cup is provided. In the region of the hopper-shaped contours 11, 14, the molding member 15 has a wall 10. This wall 10 forms an axial restriction for the provided cup, in conjunction with the wall 10 of the forming member 15 located oppositely. In order to be able to adapt the device 1 to a wide variety of cup lengths, the distance between the two molded members 15 or the distance between the receiving parts 5, 6 is variable. This can be realized, for example, by attaching the forming member 15 of one receiving part to a holding device having a long hole. However, the wall 10 does not extend into the area of the recess 7. Thereby, the cup 2 in which the cup tip 4 is held in the vertical direction in the recess 7 can be moved in the horizontal direction.

  FIG. 1 shows the state of the device 1 with the cup 2 just fed. This cup 2 is provided in any orientation, horizontally, for example using a falling flap not shown. In this case, arbitrary orientation means that the cup tip 4 is located at which cup end and the cup base 3 is located at which cup end. In the embodiment shown, the slide element 8 is operated when the cup 2 is provided, i.e. it is pushed out. At this time, the cup 2 first falls into a narrow hopper-shaped contour 14 formed by the hopper metal thin plate 12 and the slide element 8. The contour portion 14 holds the cup base 3 and the cup tip 4. This reduces the drop height of the cup 2 and brings the cup 2 to a defined position. However, as an alternative, the slide element 8 may be inserted (retracted) when the cup 2 is provided. In this case, the cup 2 falls directly into the hopper-shaped contour 11 formed from the hopper metal thin plates 12 and 13.

  In the illustrated embodiment, starting from the state shown in FIG. 1, the slide elements 8 of both receiving portions 5 and 6 are run simultaneously. The cup 2 reaches the position shown in FIGS. Here, the cup base 3 disposed in the receiving portion 5 is held in a hopper-shaped contour portion 11 formed from the hopper metal thin plates 12 and 13. The cup tip 4 falls through the intermediate chamber 9 of the hopper-shaped contour 11 of the receiving part 6. However, the cup tip 4 is received by the recess 7 and does not fall further in the vertical direction.

  The slide element 8 is operated starting from the state shown in FIGS. 2 and 3, that is, operated simultaneously in both receiving portions 5 and 6. That is, it is not necessary for the function of the device 1 to detect the orientation of the cup by the sensor. The slide element 8 captures the cup base 3 located in the receiving part 5 and pushes out the cup 2 in the axial direction. In this case, the molding member 15 is formed so that the cup tip 4 positioned in the recess 7 of the receiving portion 6 can follow this axial movement and does not limit the movement. The slide element 8 of the receiving part 6 does not capture the cup tip 4 located in the recess 7. The state described above is shown in FIGS.

  As soon as the slide element 8 is fully run, the cup base 3 is no longer held in the hopper-shaped contour 11 and falls, as shown in FIGS. The cup 2 falls into a dropping cylinder (not shown) with the cup base 3 first, and is supplied to an insertion portion (not shown).

  In the further course of the dropping process, the cup tip 4 is detached from the recess 7 as shown in FIGS. And now the next cup 2 to be redirected can be supplied to the receiving parts 5, 6.
