Definitions

  • the present invention relates to a yarn supplying bobbin feeding device that supplies a yarn supplying bobbin on which a yarn has been wound.
  • a yarn supplying bobbin feeding device disclosed in JP 2008-230830 A transports yarn supplying bobbins, on which a yarn has been wound, by using a vibration feeder.
  • the yarn supplying bobbins transported by the vibration feeder are dropped into a parts feeder bowl in which the yarn supplying bobbins are aligned.
  • the yarn supplying bobbins fed by the vibration feeder there are situations where the yarn ends are pulled out for a considerable length from the surface of the yarn supplying bobbins, or the yarn ends of a plurality of yarn supplying bobbins get entangled with each other.
  • a yarn end cutting device that can cut the yarn ends is arranged between the vibration feeder and the parts feeder bowl in the transport direction of the yarn supplying bobbins.
  • the yarn end cutting device includes a guiding member that guides the yarn supplying bobbins to downstream side in a transport direction of the yarn supplying bobbins, and a cutter that cuts the yarn ends extending from the yarn supplying bobbins.
  • a yarn end cutting device having a slit formed in the guiding member, for sucking the yarn ends is known in the art. More specifically, such a yarn end cutting device is connected to a suction source that generates a negative pressure by rotating a fan by using a motor, for example, and sucks the yarn ends of the yarns wound on the yarn supplying bobbins through this slit.
  • the yarn ends extending from the yarn supplying bobbins can be sucked, captured, and cut. Because the cut yarn ends are removed by suction as it is, the time and effort for collecting the yarn ends is also reduced.
  • the supply of the yarn supplying bobbins to the yarn end cutting device is not always continuous. For example, if the supply of yarn supplying bobbins to the vibration feeder is temporarily interrupted, the supply of yarn supplying bobbins to the yarn end cutting device is also temporarily interrupted. If the supply of the yarn supplying bobbins is interrupted but the negative pressure is continuously generated by the suction source, the suction source consumes power wastefully. On the other hand, for example, if the power supply of the suction source is turned on/off depending on whether the yarn supplying bobbin is supplied, it takes time and effort, and there is a possibility that the production efficiency may be reduced.
  • one object of the present invention is to easily reduce power consumption of a suction source to which a yarn end cutting device is connected.
  • a yarn supplying bobbin feeding device includes a yarn supplying bobbin transport device that transports a plurality of yarn supplying bobbins on which a yarn has been wound; a yarn supplying bobbin aligning device that aligns the yarn supplying bobbins and that is arranged downstream of the yarn supplying bobbin transport device in a transport direction of the yarn supplying bobbins; and a yarn end cutting device that includes a cutting member for cutting yarn ends extending from the yarn supplying bobbins and that is arranged between the yarn supplying bobbin transport device and the yarn supplying bobbin aligning device in the transport direction.
  • the yarn end cutting device includes a suction member having a suction vent connected to a suction source and that sucks the yarn ends by the action of a negative pressure supplied thereto by the suction source via the suction vent; a connecting member in which a communication path that connects the suction vent and the suction source is formed; and an opening/closing member capable of switching, by opening and closing at least one of the suction vent and the communication path, the suction member between a supply state in which the negative pressure is supplied via the suction vent and a non-supply state in which the negative pressure is not supplied via the suction vent.
  • the up-down direction in FIG. 1 is defined as a vertical direction (up-down direction) in which the gravity acts.
  • a left-right direction in FIG. 2 is defined as a front-back direction.
  • a direction orthogonal to both the up-down direction and the front-back direction is defined as a left-right direction.
  • the yarn winding equipment 1 includes the yarn supplying bobbin feeding device 2, a yarn supplying bobbin processing device 3, a yarn winding machine 4, and a main controller 5.
  • the yarn supplying bobbin feeding device 2 transports yarn supplying bobbins B and supplies them to the yarn supplying bobbin processing device 3.
  • a yarn has been wound on each of the yarn supplying bobbins B by a not-shown spinning machine that spins the yarn.
  • the yarn supplying bobbin processing device 3 performs a predetermined process so that the yarn wound on the yarn supplying bobbin B can be smoothly unwound by the yarn winding machine 4.
  • the yarn winding machine 4 includes a plurality of winding units 4a. Each winding unit 4a unwinds the yarn from a yarn supplying bobbin B, and forms a package by winding the yarn on a winding yarn supplying bobbin while removing any yarn defects in the yarn.
  • the main controller 5 controls the entire yarn winding equipment 1 in an integrated manner.
  • the yarn winding equipment 1 includes a suction source 6 for sucking a yarn end Y (see FIG. 3 ) extending from the yarn supplying bobbin B fed by the yarn supplying bobbin feeding device 2 (see FIG. 3 , details will be given later).

  • the yarn supplying bobbin receiving box 11 is a container in which the yarn supplying bobbins B on which the yarn has been wound are put.
  • the yarn supplying bobbin receiving box 11 is arranged at a back end of the yarn supplying bobbin feeding device 2.
  • the yarn supplying bobbin receiving box 11 is movable between an initial position thereof (see a box shown with a solid line) and a supply position thereof (see a box shown with a two-dot chain line).
  • a hydraulic cylinder 11a for example, is used to move the yarn supplying bobbin receiving box 11.
  • the yarn supplying bobbins B are put into the yarn supplying bobbin receiving box 11 manually by an operator or by a not-shown yarn supplying bobbin introducing device.

  • the yarn end cutting device 13 includes the guiding member 31 (see FIG. 3 and FIGS. 4A to 4C ) that guides the yarn supplying bobbins B, and a plurality of cutting members 32 capable of cutting the yarn ends Y (see FIG. 4B ). As will be described later, the yarn end cutting device 13 is capable of sucking and capturing the yarn ends Y.
  • the guiding member 31 (a suction member according to the present invention) is a member formed by sheet metal processing a metal plate, for example.
  • the guiding member 31 is arranged above the bowl member 42 of the yarn supplying bobbin aligning device 14 (see FIG. 3 ).

  • the motor 6a is driven and controlled by the main controller 5, for example, so as to rotate at a constant rotational speed.
  • the suction vent 54 of the guiding member 31 is connected to the suction source 6 via a connecting member 71 and a flexible hose 72.
  • the connecting member 71 and the flexible hose 72 will be described in detail later.
  • the yarn end cutting device 13 can suck the yarn ends Y extending from the yarn supplying bobbins B via the suction vent 54.
  • the connecting member 71 is a hollow member attached to a lower surface of the bottom part 52 of the guiding member 31.
  • the connecting member 71 has an opening 73 that has a shape similar to the suction vent 54 of the guiding member 31.
  • An internal space 74 of the connecting member 71 communicates with the suction vent 54 via the opening 73.
  • the connecting member 71 is connected to the flexible hose 72.
  • the flexible hose 72 is, for example, a bendable hose having a bellows structure. One end of the flexible hose 72 is connected to the connecting member 71, and the other end is connected to the suction source 6.

  • FIGS. 5A to 5C are explanatory diagrams showing the movement of the yarn ends Y when the yarn supplying bobbins B pass through the yarn end cutting device 13.
  • FIGS. 5A to 5C only one yarn supplying bobbin B has been shown in FIGS. 5A to 5C .
  • the yarn supplying bobbin B is transported to the downstream side end in the transport direction of the placement path 21 by the yarn supplying bobbin transport device 12 (see FIG. 5A ). Thereafter, the yarn supplying bobbin B slides under its own weight while being guided along the guide path 51 (see FIG. 5B ). While the yarn supplying bobbin B is moving along the guide path 51, the yarn end Y extending from the yarn supplying bobbin B is sucked and captured by the action of the negative pressure supplied via the suction vent 54. Then, the yarn supplying bobbin B moves to the tip end in the guiding direction of the guide path 51 and then falls from the guiding member 31 by its own weight (see a two-dot chain line in FIG. 5B ).
  • a middle part of the yarn end Y is guided to the proximal end side in the guiding direction by one of the yarn end guide slits 55, and this yarn end Y enters the tip end on the proximal end side in the guiding direction of this yarn end guide slit 55 (see a two-dot chain arrow in FIG. 5C ).
  • the yarn end Y that has entered the tip end on the proximal end side in the guiding direction of the yarn end guide slit 55 is cut by the cutting member 32 (see FIG. 4B ).
  • the tip end side part of the cut yarn end Y is removed by suction via the communication path 76 (see FIG. 4C ).
  • the supply of the yarn supplying bobbins B to the yarn end cutting device 13 is not always continuous. For example, if the supply of yarn supplying bobbins B to the yarn supplying bobbin transport device 12 is temporarily interrupted, the supply of yarn supplying bobbins B to the yarn end cutting device 13 is also temporarily interrupted. If the supply of the yarn supplying bobbins B is interrupted but the negative pressure is continuously generated by the suction source 6, the suction source 6 consumes power wastefully. On the other hand, for example, if the power supply of the suction source 6 is turned on/off depending on whether the yarn supplying bobbins B are supplied, it takes time and effort, and there is a possibility that the production efficiency may be reduced. Therefore, in order to easily reduce the power consumption of the suction source 6 to which the yarn end cutting device 13 is connected, the yarn end cutting device 13 has an opening/closing member 80 described later.
  • FIG. 6A is a front view of the opening/closing member 80 and its surrounding structure.
  • FIG. 6B is a cross-sectional view along a line VI(b)-VI(b) shown in FIG. 6A .
  • the yarn end cutting device 13 includes the opening/closing member 80.
  • the opening/closing member 80 is capable of opening and closing the flexible hose 72 that is a part of the connecting member described above.
  • the opening/closing member 80 is arranged in front of the housing 41 of the yarn supplying bobbin aligning device 14.
  • the opening/closing member 80 includes a casing 81, a shutter 82, and a shutter moving mechanism 83.
  • the casing 81 is a member in which a sealed space is formed.
  • the flexible hose 72 is connected to the casing 81. More specifically, one end of a first flexible hose 84, which is provided on the yarn end cutting device 13 side, is connected to a front end of the casing 81. One end of a second flexible hose 85, which is provided on the suction source 6 side, is connected to a back end of the casing 81.
  • the shutter 82 is a plate-like member arranged inside the casing 81.
  • the shutter 82 functions to open and close an opening 84a on one end side of the first flexible hose 84, for example.
  • a surface area of an end face of the shutter 82 is larger than a surface area of the opening 84a.
  • the shutter 82 is driven to move by the shutter moving mechanism 83.
  • the shutter moving mechanism 83 is a mechanism that switches the positions of the shutter 82.
  • the shutter moving mechanism 83 is, for example, a ball screw mechanism having a screw shaft 86 extending in the up-down direction and a nut 87 screwed to the screw shaft 86.
  • the structure of the shutter moving mechanism 83 is not limited to the one mentioned here.
  • the shutter 82 is fixed to the nut 87.
  • the screw shaft 86 is rotationally driven by a motor 88.
  • the motor 88 is driven and controlled by the control device 15.
  • the shutter 82 is movable between an open position (see a solid line in FIG. 6B ) at which the opening 84a of the first flexible hose 84 is completely open, and a closed position (see a two-dot chain line in FIG. 6B ) at which the opening 84a is completely covered and closed by the shutter 82. Also, the shutter 82 can be moved to, for example, a half-open position (see a one-dot chain line in FIG. 6B ) at which the opening 84a is only half-opened. As described above, the opening/closing member 80 is capable of adjusting an opening degree of the first flexible hose 84.
  • the negative pressure is supplied by the suction source 6 via the suction vent 54 of the guiding member 31 (see FIG. 4A , etc.) (that is, the suction member is in a supply state).
  • the fan 6b is rotated by the motor 6a of the suction source 6 so that the air near the suction vent 54 of the guiding member 31 is discharged through the internal space 74 of the connecting member 71 and the internal space 75 of the flexible hose 72 resulting in the supply of the negative pressure to the space near the suction vent 54.
  • the shutter 82 is in the closed position, no negative pressure is supplied through the suction vent 54 (that is, the suction member is in a non-supply state).
  • FIGS. 7A and 7B are explanatory views showing a swinging mechanism 90 that swings the guiding member 31.
  • the yarn supplying bobbins B are transported by the yarn supplying bobbin transport device 12 in an overlapping and piled state (see FIG. 7A ). For this reason, for example, the yarn supplying bobbins B may not move as desired on the guide path 51. Also, the yarn ends Y may not be sucked because the yarn ends Y may be sandwiched between the yarn supplying bobbins B. To address this issue, the yarn end cutting device 13 further includes the swinging mechanism 90.
  • the swinging mechanism 90 includes the support members 56 and air cylinders 93 (a first swing drive member according to the present invention).
  • the support member 56 is, for example, an L-shaped member (see FIG. 3 ). As one specific example, a part of the support member 56 extending in the up-down direction is fixed to the housing 41 of the yarn supplying bobbin aligning device 14 (see FIG. 3 ). A part extending in the left-right direction of the support member 56 is a swing axis that supports the side member 53 of the guiding member 31 so as to be swingable (see FIGS. 4A to 4C ). A back end of the side members 53 is supported from below by the support members 57 (see FIG. 4A , etc.). As a specific example, as shown in FIG. 4A and FIGS.
  • a right end part of the support member 57 on the left (support member 91) is notched to form an upward-facing surface 91a.
  • a left end part of the support member 57 on the right (support member 92) is notched to form an upward-facing surface 92a.
  • the back ends of the side members 53 of the guiding member 31 are supported by the support members 91 and 92 when the back ends touch these surfaces 91a and 92a by riding on the surfaces 91a and 92a.
  • Each air cylinder 93 has a piston rod 94 that can extend and contract in the substantially up-down direction.
  • a tip end of the piston rod 94 is attached to a back end part of the side member 53 of the guiding member 31.
  • the air cylinder 93 is connected to a not-shown compressed air source.
  • compressed air is supplied to the air cylinder 93 by the compressed air source via a not-shown pipe, the piston rod 94 extends, and when the compressed air is discharged from the air cylinder 93, the piston rod 94 contracts.
  • the supply and discharge of compressed air can be switched by a not-shown solenoid valve that can be controlled by the control device 15, for example.
  • the guiding member 31 swings in the substantially up-down direction with the support members 56 as the swing axis (see an arrow in FIG. 7B ).
  • the yarn supplying bobbins B present on the guide path 51 rock.
  • the pile of the yarn supplying bobbins B can be collapsed.
  • the control device 15 can temporarily stop the operation of the yarn supplying bobbin transport device 12.
  • the guiding member 31 is swinging, falling of the yarn supplying bobbins B through the gap between the placement member 22 of the yarn supplying bobbin transport device 12 and the guiding member 31 of the yarn end cutting device 13 can be prevented.
  • the opening/closing member 80 can easily reduce the power consumption of the suction source 6 to which the yarn end cutting device 13 is connected.
  • the opening degree of the flexible hose 72 by using the opening/closing member 80, the absolute value of the supplied negative pressure can be changed. Therefore, the load on the suction source 6 can be effectively reduced depending on the yarn type and the like.
  • the suction vent 54 is formed in the guiding member 31. For this reason, compared with the case where the suction vent 54 is formed in a member other than the guiding member 31, the increase in the number of components can be suppressed. Moreover, the yarn ends Y extending from the yarn supplying bobbins B that are moving on the guide path 51 can be sucked easily.
  • the guiding member 31 is proactively driven to swing by the air cylinders 93. Therefore, even if the yarn supplying bobbins B are transported in the piled state, the yarn supplying bobbins B present on the guide path 51 are rocked whereby the pile of the yarn supplying bobbins B can be collapsed.
  • the yarn ends Y of the yarn supplying bobbins B can be sucked in advance through the suction vent 54 arranged on the proximal end side in the guiding direction (that is, upstream side in the transport direction) than the yarn end guide slits 55.
  • the middle part of the yarn ends Y can be made to enter at least in the yarn end guide slits 55 that extend the other side in the guiding direction. Therefore, the yarn ends Y that have entered the yarn end guide slits 55 can be surely cut by the cutter 61.
  • a yarn supplying bobbin feeding device includes a yarn supplying bobbin transport device that transports a plurality of yarn supplying bobbins on which a yarn has been wound; a yarn supplying bobbin aligning device that aligns the yarn supplying bobbins and that is arranged downstream of the yarn supplying bobbin transport device in a transport direction of the yarn supplying bobbins; and a yarn end cutting device that includes a cutting member for cutting yarn ends extending from the yarn supplying bobbins and that is arranged between the yarn supplying bobbin transport device and the yarn supplying bobbin aligning device in the transport direction.
  • the yarn end cutting device includes a suction member having a suction vent connected to a suction source and that sucks the yarn ends by the action of a negative pressure supplied thereto by the suction source via the suction port; a connecting member in which a communication path that connects the suction vent and the suction source is formed; and an opening/closing member capable of switching, by opening and closing at least one of the suction vent and the communication path, the suction member between a supply state in which the negative pressure is supplied via the suction vent and a non-supply state in which the negative pressure is not supplied via the suction vent.
  • the yarn ends extending from the yarn supplying bobbins are sucked and captured.
  • the load on the suction source is lower than in the supply state, and the suction source consumes less power. Therefore, the power consumption of the suction source to which the yarn end cutting device is connected can be easily reduced by the opening/closing member.
  • the opening/closing member is capable of adjusting an opening degree of at least one of the suction vent and the communication path.
  • the absolute value of the supplied negative pressure can be changed by adjusting the opening degree of at least one of the suction vent and the communication path by the opening/closing member. Therefore, the load on the suction source can be effectively reduced depending on the yarn type and the like.
  • the yarn end cutting device includes a guiding member formed with a guide path for guiding the yarn supplying bobbins to a downstream side in the transport direction, and the suction vent is formed in the guiding member.
  • an increase in the number of components can be suppressed as compared to a case in which the suction vent is formed in a member other than the guiding member. Moreover, the yarn ends extending from the yarn supplying bobbins that are moving on the guide path can be sucked easily.
  • the yarn end cutting device includes a guiding member formed with a guide path for guiding the yarn supplying bobbins to a downstream side in the transport direction; and a first swing drive member that swings the guiding member.
  • the yarn supplying bobbins are transported by the yarn supplying bobbin transport device in an overlapping and piled state, for example, there is a possibility that the yarn supplying bobbins do not move as desired on the guide path. Also, the yarn ends may not be sucked by the suction member because the yarn ends may be sandwiched between the yarn supplying bobbins.
  • the guiding member is proactively swung by the first swing drive member. Therefore, even when the yarn supplying bobbins are transported in the overlapping state, the pile of the yarn supplying bobbins can be collapsed by causing the yarn supplying bobbins on the guide path to rock.
  • the yarn end cutting device includes a guiding member formed with a guide path for guiding the yarn supplying bobbins to a downstream side in the transport direction; a swing member capable of swinging in a space above the guide path; and a second swing drive member that swings the swing member.
  • the swing member can be caused to interfere with the yarn supplying bobbins by swinging the swing member in the space above the guide path. Therefore, even when the yarn supplying bobbins are transported in the overlapping state, the pile of the yarn supplying bobbins on the guide path can be collapsed by the swing member.
  • the yarn supplying bobbin aligning device includes a receiving member that opens upward and receives the yarn supplying bobbins
  • the yarn end cutting device includes a guiding member that is arranged above the receiving member and formed with a guide path for guiding the yarn supplying bobbins to one side in a predetermined guiding direction that is orthogonal to a vertical direction, a yarn end guide slit that extends at least to other side in the guiding direction is formed at an end of the guiding member on the one side in the guiding direction, the suction vent is arranged on the other side in the guiding direction with respect to the yarn end guide slit, and the cutting member includes a cutter capable of cutting the yarn end that has entered an end portion of the yarn end guide slit on the other side in the guiding direction.
  • the yarn supplying bobbins are received by the receiving member of the yarn supplying bobbin aligning device when the yarn supplying bobbins drop by their own weight from the downstream side end (i.e., an end portion on the one side in the guiding direction) of the guiding member in the transport direction. Therefore, before the yarn supplying bobbins fall from the guiding member, the yarn ends can be sucked through the suction vent that is arranged more on the other side in the guiding direction (i.e., the upstream side in the transport direction) than the yarn end guide slit.
  • the middle part of the yarn ends can be made to enter at least the yarn end guide slit that extends to the other side in the guiding direction. Therefore, the yarn ends that have entered the yarn end guide slit can be cut surely by the cutter.
  • the yarn end cutting device includes a blowing member that is arranged on the one side with respect to the yarn end guide slit in the guiding direction and that blows gas toward at least the other side in the guiding direction toward the guiding member.
  • the yarn ends extending from the yarn supplying bobbins can be proactively moved to at least the other side in the guiding direction. Therefore, the yarn ends can be easily inserted into the yarn end guide slit.
  • the opening/closing member includes the cutting member, and the cutting member includes a cutter member capable of opening and closing the suction vent and capable of cutting the yarn end when closing the suction vent.
  • the opening/closing member simply switches the state of the suction member between the supply state and the non-supply state, if the sucked yarn end entangles with the opening/closing member, the opening/closing member may not operate as desired, also, there is a chance that the opening/closing member malfunctions.
  • the opening/closing member also cuts the yarn end. The cut yarn end is sucked and removed by the suction member. As a result, entangling of the yarn ends with the opening/closing member can be prevented, and the occurrence of malfunctioning of the opening/closing member can be suppressed.
  • the yarn end cutting device includes a plurality of the cutting members, and each cutting member includes the suction member.
  • a suction vent is provided corresponding to each cutting member. Therefore, it is possible to easily suck and capture the yarn end located near the cutting member.
