Description

  The present invention includes an entry side into which the yarn sheet enters, a beam, a front side on the opposite side of the entry side across the beam, and a lead having an operating position between the entry side and the beam. The present invention relates to a rewinding device.

  Such a rewinding device is used to wind the yarn sheet onto a beam that can be used later on a loom or knitting machine. The yarn sheet passes through the pretreatment station several times before winding into a beam, also called “beaming”. In this pretreatment station, for example, a sizing agent is applied to the yarn sheet. At this time, in order to avoid sticking of the yarn over a wide range, the yarn sheet is passed through the lead. This lead is finally defined by the width of the beam.

The rear side of the rewinding device is an entry side into which the yarn sheet is fed. On the opposite front side is an operating element. When executing the specific function of the rewinding device, the operator can reach and operate the operating element. (For example, see Patent Document 1)
German Patent Application Publication No. 3149984

  When starting a new rewinding stroke, the lead is engaged with the yarn sheet. Leads typically have a number of “compartments” that open upward. These sections are separated from each other by a separating element such as a pin protruding upward. It is desirable to distribute the yarns to the compartments uniformly to some extent. However, when the lead enters the incoming yarn sheet from below, the yarn may not be evenly distributed across all sections, resulting in undesirable rewinding results. In that case, the operator must redistribute the yarns to the individual compartments with his hand. At this time, the operator has to work on the rewinding device. This work needs to be performed at the lead operating position, is cumbersome and time consuming, and the risk of accidents is high.

  An object of the present invention is to reduce the risk of accidents.

  The problem is that, as in the winding device of the present invention, the entry side into which the yarn sheet enters, the beam, the front region on the opposite side of the entry side across the beam, the entry side, and the beam In a rewinding device having a lead having an operating position between the lead and the lead, the lead is movable from the operating position to a non-operating position in the front region.

  The front region is the machine half between the vertical plane passing through the beam axis and the front side. A lead in this area is an area accessible to an operator standing in front of the apparatus. The distance between the position where the operator stands and the lead is shorter than the average length of the operator's arm. In other words, this distance is the distance that the operator's hand reaches the reed, and if this distance is reached, the operator can re-distribute the non-uniformly arranged yarn into another section to obtain a uniform yarn distribution. it can. The lead moves substantially parallel to the yarn traveling direction of the yarn sheet to be wound around the beam. This applies not only to movement from the operating position to the non-operating position, but also to movement from the non-operating position to the operating position. Thereby, the movement of the lead does not disturb the trajectory of the yarn sheet.

  In the above invention, it is preferable that at least a part of a configuration of the approach roll device disposed between the lead and the beam is configured to be movable toward the front side. With such a configuration, one or a plurality of rolls of the entry roll device moves together with the lead, so that there is no change in the arrangement of the yarn sheet between the lead and the entrance roll device entrance, and the state is left as it is. be able to. That is, the arrangement of the yarn sheet during this time is not disturbed by the movement of the lead, or is not affected by other adverse effects.

  In the above invention, the entry roll device has one entrance roll and at least one exit roll disposed between the entrance roll and the front side, and the entrance roll is disposed from the entry side toward the entry roll. It is preferable to be configured to pass through the outlet roll and move toward the front side. With such a configuration, the entrance roll is the first roll of the entry roll device as viewed from the lead in the path of the yarn sheet from the entry side to the beam. Therefore, the movement of the inlet roll away from the reed only increases the length of the yarn that occurs between the reed and the inlet roll and outlet roll of the entry roll device. At this time, the yarn sheet fed into the rewinding device can be fed faster. As the lead and entry roll return to their original positions, the beam can be rotated to accept the excess yarn sheet. Both movements can be controlled without problems and there is little risk of twisting of the yarn sheet.

  In the above invention, the movable structure of the entry roll device and the lead are preferably provided on the support. With such a configuration, the relationship between the lead and the movable configuration of the approach roll device does not change even if the support moves. Therefore, it is not necessary to cost additional control for moving the lead and the above-described structure integrally.

  In the above invention, it is preferable that the front side of the approach roll device is covered with a protection mechanism, and the protection mechanism is configured to be movable together with the lead. Thereby, it becomes possible to provide a protection mechanism at a position where the maximum safety and the best accessibility for the operator are guaranteed with respect to the approach roll device.

  In the above invention, the protection mechanism is preferably configured to have an inclination angle adjustable by movement of the lead. The protection mechanism is generally tilted so that the operator can monitor the traveling of the yarn sheet by viewing the entry roll device through the protection mechanism. With the above configuration, when the lead is moved to the non-operating position, the protection mechanism is further sharpened. In that case, the operator can take a position closer to the lead, and the lead can be more easily accessible to the operator. In that case, the protection mechanism is no longer an obstacle as it approaches the lead.

  In the above invention, it is preferable that the protection mechanism is pivotally supported by the support body and supported by a guide track, and the guide track has a step on the front side. As long as the protection mechanism is supported on the guide track, the protection mechanism maintains its tilt angle. Only after the protection mechanism exceeds the step, the protection mechanism is inclined more steeply. At this time, the guide track need not be formed beyond the step. That is, the guide track can be terminated at a step. In that case, the protection mechanism is simply articulated and suspended from the support when the lead is in the non-operating position. In this case, the protection mechanism is suspended substantially vertically by the action of gravity.

  In the above invention, the protection mechanism has a frame and a cover that can be placed on the frame, and the cover can swing downward through the guide track when the lead is in the non-operating position. Composed. In that case, the cover is opened to open the additional space. Through this space, the operator can reach the reed and it is easier to reach the reed. Since the cover can swing downward through the guide track, the height of the cover does not protrude from the front side of the rewinding device, and it is not difficult for the operator to approach the lead.

  According to the present invention, the risk of an accident can be reduced.

  The invention will now be described on the basis of a preferred embodiment in conjunction with the drawings.

  The yarn sheet 2 is wound around the beam 3 in the winding device 1 shown in FIGS. At that time, the yarn sheet 2 is fed into the rewinding device 1 from the entry side 4. In FIG. 3, the yarn sheet 2 is not shown for the purpose of making each configuration of the rewinding device 1 easier to see. As shown in FIG. 4 to be described later, the yarn sheet 2 passes through a lead 5 and an entrance roll device 6 including an entrance roll 7, an intermediate roll 8, and an exit roll 9, and reaches the beam 3. The beam 3 has one winding shaft 10 and two end plates 11 and 12. The width of the beam 3 is finally determined by the distance between the two end plates 11 and 12 in the axial direction. The lead 5 is composed of an extension type lead in order to match the width of the yarn sheet 2 and the width of the beam 3. That is, the lead 5 is configured so that its width is variable. The lead 5 is indicated by a zigzag line in FIG. At the tip of the zigzag line, for example, guide elements such as needles are provided so as to protrude upward. When the lead 5 contracts in the axial direction of the beam 3, the interval between the needles in the axial direction is shortened. As the lead 5 is stretched, the needle spacing is correspondingly increased.

  The operator 13 can stand on the front side 14 of the rewinding device 1 to perform a specific operation. An abbreviated display screen 15 and keyboard 16 are provided in the electronic adjustment and control unit. The operator 13 can input specific parameters in the rewinding process by using the keyboard 16.

  The height of the lead 5 can be adjusted by the vertical drive device 17. Therefore, at first, the yarn sheet 2 is passed through the inlet roll 7 without hitting the lead 5. When the yarn sheet 2 is fixed to the beam 3 and a certain tension is applied to the yarn sheet 2, the lead 5 is fed into the yarn sheet 2 from below.

  FIG. 4 shows a part of the rewinding device 1 in the operating position of the lead 5. Here, the lead 5 is arranged in one area of the yarn sheet 2 between the entry side 4 and the beam 3. More precisely, the lead 5 is arranged in an area of the yarn sheet 2 between the entry side 4 and the entry roll device 6. In general, the lead 5 is arranged between the entry side 4 and a vertical plane passing through the axis 18 of the beam 3. However, the lead 5 can be provided closer to the front side 14. In any case, the lead 5 is in a position where the operator can easily reach the hand even when it is in the operating position. However, in order to reach the lead 5 in this operating position, the operator 13 has to get on the rewinding device. For example, the lead 5 has to be extended to reach the yarn sheet 2 from the bottom, and the yarn distribution is such that the yarns are arranged in various sections in the lead 5. This is a case where the thread sheet 2 is generated. In that case, the operator 13 must re-separate the thread by hand.

  The lead 5 and the inlet roll 7 are provided on the support 19. As can be seen from a comparison between FIG. 4 and FIG. 6, the support 19 is configured to be movable from the operating position shown in FIG. 4 to the non-operating position shown in FIG. 6 (see the phantom line in FIG. 4). . The lead 5 is located closer to the front side 14 than the intermediate roll 8 of the entry roll device 6 when in the non-operating position. FIG. 2 shows the lead 5 in this non-operating position. From FIG. 2, it can be seen that this non-operating position is a position where the hand of the operator 13 standing on the front side 14 of the rewinding device 1 reaches the lead 5. That is, in order for the hand of the operator 13 to reach the lead 5, the operator 13 only has to reach out through the entrance roll 7. The remaining configuration of the approach roll device 6 except the beam 3 and the entrance roll 7, in particular the intermediate roll 8, does not get in the way. In the present embodiment, the distance between the lead 5 in the non-operating position and the front side 14 is less than 40 cm.

  When the lead 5 moves together with the inlet roll 7 to the non-operation position shown in FIG. 6 (see the phantom line in FIG. 4), the path through which the yarn sheet 2 moves from the entry side 4 to the beam 3 becomes longer. However, the length of the yarn sheet 2 required for this can be replenished from the entry side 4 during the guide stroke. That is, the yarn sheet 2 is further fed from the entry side 4. During this movement, the beam 3 stops at the non-operating position without moving.

  On the other hand, when the support 19 moves from the non-operating position shown in FIG. 6 (see the phantom line in FIG. 4) to the operating position shown in FIG. 4 (see the solid line in FIG. 4), it moves between the entrance side 4 and the beam 3. The path along which the yarn sheet 2 moves is shortened. Therefore, since the yarn sheet 2 is left over, the beam 3 is turned in the winding direction in order to receive the excess, and the excess is collected by the beam 3.

  The protection mechanism 20 has a cover 21 and moves together with the support 19. That is, the protection mechanism 20 moves together with the lead 5. And the cover 21 is comprised so that the approach roll apparatus 6 may be covered and closed by contacting the frame 22. FIG. The cover 21 is provided on the frame 22 so as to be swingable, and has a grip 23 for allowing it to swing down. As shown in FIG. 5, this swinging down can also be performed when the lead 5 is in the operating position. When the operator 13 swings and descends at the operating position, the operator 13 can visually observe the entry roll device 6 through the frame 22. Moreover, depending on the case, a hand can also be reached to the approach roll apparatus 6. FIG. The cover 21 is placed on the lateral support 24 with its grip 23. The lateral support 24 extends over the entire width of the winding device 1.

  The upper end of the frame 22 is pivotally supported by the support body 19, that is, is configured to be articulated with the support body 19. Further, the frame 22 has traveling wheels 25 at the lower end, and these traveling wheels 25 roll on a guide track 26 provided on the upper surface of the lateral support 24. While the traveling wheel 25 rolls on the guide track 26, the inclination angle of the frame 22 does not change. That is, the frame 22 has the inclination shown in FIGS.

  However, the guide track 26 terminates at the front side 14 of the winding device 1. The guide track 26 forms a step there. When the traveling wheel 25 passes this step, the frame 22 tilts to a substantially vertical position as shown in FIGS. That is, the inclination angle of the frame 22 changes. Next, the traveling wheel 25 is suspended in front of the lateral support 24. Therefore, the protection mechanism 20 does not require a very large space to open the inside of the frame 22, and the operator 13 can reach the lead 5 more easily.

  In this position, the cover 21 can also swing down below the lateral support 24, the bent end 27 no longer protrudes upward from the inlet roll 7, and the operator 13 is even better on the lead 5. You can reach out.

The winding device seen from the front side is shown. It is a side view of a rewinding device. It is a top view of a winding device. It is an enlarged view of a part of the rewinding device with the lead in the operating position. FIG. 5 is an enlarged view in which the protective mechanism is opened in the rewinding device shown in FIG. 4. FIG. 5 is an enlarged view of a rewinding device shown in FIG. 4 in which a lead is in a non-operation position. FIG. 7 is an enlarged view in which the protective mechanism-cover is swung down in the rewinding device shown in FIG. 6.
