Description

  The present invention mainly relates to a yarn supplying bobbin supplying device for supplying a yarn supplying bobbin wound with a yarn to an automatic winder.

  Patent Document 1 discloses a yarn feeding bobbin supply device provided in an automatic winder in order to supply a yarn feeding bobbin wound with yarn spun by a spinning machine to each winder unit of the automatic winder. This supply device is configured to unload the yarn supply bobbin in the wagon in stages on a conveyor by inverting and tilting the wagon (box-like body) in which the yarn supply bobbin is stacked in the inside with a packing device. It has become. The yarn supplying bobbin supplied onto the conveyor in this manner is supplied to the downstream vibrating conveyor while cutting the pile of yarn supplying bobbins by driving the conveyor. The vibration conveyor conveys the yarn supplying bobbins one by one while supplying them to the direction determining unit, and the direction determining unit determines the direction of the yarn supplying bobbin. Thereafter, the yarn feeding bobbin is dropped on the alignment chute and supplied from above to the peg of the tray for feeding the yarn feeding bobbin to the winder unit.

  In Patent Document 1, a yarn feeding bobbin supply device includes a chain for driving a movable frame in which a wagon is set. The chain is provided with a dock, and the yarn feeding bobbin supply device includes a three-stage limit switch with which the dock can contact. With this configuration, when the chain is driven and the wagon is tilted, the chain drive is temporarily stopped each time the dock comes into contact with each of the three-stage limit switches, and the angular position of the wagon is maintained, and then fed onto the conveyor. The chain drive is resumed after waiting for the sensor to detect that the thread bobbin is not present. With this control, the wagon can be gradually lowered in stages, and the yarn feeding bobbins in the wagon can be unloaded little by little on the conveyor.

Japanese Patent Laid-Open No. 7-133015

  By the way, even if there is enough yarn bobbin remaining in the wagon, depending on the condition of the yarn feeding bobbin in the wagon, the yarn feeding bobbin does not move even when the wagon is tilted for unloading. There is a case where a certain amount of time is required until unloading (that is, actual feeding of the yarn feeding bobbin) without coming out of the wagon immediately. In this regard, although the configuration of Patent Document 1 can tilt the wagon step by step, if the yarn feeding bobbin is not immediately put in, the control of immediately increasing the wagon tilt to the next step is performed. In some cases, an excessive amount of yarn feeding bobbins are supplied from the wagon onto the conveyor. As a result, the conveyor and the vibration conveyor may overflow with the yarn feeding bobbins and hinder the supply work, or may cause damage to the vibration conveyor and the like, and improvement has been desired.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a yarn feeding bobbin supply device that can reliably supply yarn feeding bobbins in a box-like body little by little.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to a first aspect of the present invention, a yarn feeding bobbin supply device having the following configuration is provided. That is, the yarn feeding bobbin supply device includes a box-shaped body, an actuator, a transport unit, a bobbin amount confirmation unit, and an actuator control unit. The box-shaped body is open at the top and accommodates a yarn feeding bobbin. The actuator is driven to tilt the box-shaped body. The said conveyance part conveys the yarn feeding bobbin supplied from the said box-shaped body inclined by the said actuator. The bobbin amount confirmation unit confirms whether or not the amount of yarn feeding bobbin supplied to the transport unit satisfies a specified supply amount. The actuator control unit controls the actuator. The actuator controller drives the actuator to incline the box-shaped body by a specified inclination amount, and after the box-shaped body is allowed to stand still for a specified stationary time in this state, the amount of the yarn feeding bobbin of the transport section is the specified volume Whether or not the supply amount is satisfied is confirmed by the bobbin amount confirmation unit, and when the yarn supply bobbin amount is less than the specified supply amount, the actuator is driven to further tilt the box-shaped body. To do.

  As a result, the yarn feeding bobbins can be gradually introduced into the conveying unit step by step. In addition, even if it takes a certain amount of time from when the box-shaped body is tilted to the specified inclination amount until the yarn feeding bobbin is loaded into the transport unit, the tilt of the box-shaped body increases if the loading is in time for the specified stationary time. There is no. Accordingly, it is possible to prevent the box-shaped body from being tilted more than necessary and an excessive yarn feeding bobbin is thrown into the transport unit at a time, so that smooth transport in the transport unit can be realized.

  The yarn feeding bobbin supplying device preferably has the following configuration. That is, the transport unit includes a bobbin receiving portion that receives a yarn feeding bobbin supplied from the box-shaped body. The bobbin amount confirmation unit confirms whether or not the amount of yarn feeding bobbin supplied to the bobbin receiving unit satisfies the specified supply amount.

  By checking the amount of yarn supply bobbin supplied from the box-shaped body to the transport unit and received by the bobbin receiving unit, it is confirmed with a simple configuration whether the amount of yarn supply bobbin satisfies the specified supply amount. can do.

  The yarn feeding bobbin supplying device preferably has the following configuration. In other words, the bobbin amount confirmation unit is a sensor that is provided in the bobbin receiving unit of the transport unit and detects the presence or absence of the yarn feeding bobbin. The specified supply amount is determined according to the mounting height of the sensor.

  Thereby, the specified supply amount can be easily adjusted by changing the mounting height of the sensor.

  According to the 2nd viewpoint of this invention, the control method of the following yarn feeding bobbin supply apparatuses is provided. That is, the yarn feeding bobbin supply device includes an actuator, a transport unit, and a bobbin amount confirmation unit. The actuator is driven to tilt the box-shaped body that accommodates the yarn feeding bobbin while being opened at the top. The said conveyance part conveys the yarn feeding bobbin which came out of the said box-shaped body inclined. The bobbin amount confirming unit confirms whether or not the amount of the yarn feeding bobbin that has come out of the box-like body and is supplied to the conveying unit satisfies a specified supply amount. The control method includes a first step, a second step, a third step, and a fourth step. In the first step, the actuator is driven to tilt the box-shaped body. In the second step, the box-shaped body is kept stationary for a specified stationary time. In the third step, the bobbin amount confirmation unit confirms the yarn feeding bobbin amount. In the fourth step, as a result of confirmation by the bobbin amount confirmation unit, when the yarn feeding bobbin is less than the specified supply amount, the actuator is driven to further tilt the box-shaped body.

  As a result, the yarn feeding bobbins can be gradually introduced into the conveying unit step by step. Even if it takes a certain amount of time from when the box-shaped body is tilted to when the yarn feeding bobbin is inserted into the conveying section, the inclination of the box-shaped body does not increase if the specified stationary time is met. Accordingly, it is possible to prevent the box-shaped body from being tilted more than necessary and an excessive yarn feeding bobbin is thrown into the transport unit at a time, so that smooth transport in the transport unit can be realized.

  In the control method of the yarn feeding bobbin supply device, it is preferable that the execution of the fourth step is stopped when the drive position of the actuator has reached the rising end during the execution of the fourth step.

  As a result, the control for tilting the box-like body beyond the limit is prevented, so that the control can be made more efficient.

FIG. 5 is a side view showing how the feeding device 3 lifts the wagon 60 and feeds the yarn feeding bobbin 10 to the conveyor 4.

  A yarn feeding bobbin supply device 1 shown in FIG. 1 supplies a yarn feeding bobbin 10 in which a yarn is wound around a core tube to a plurality of winder units constituting an automatic winder. The yarn feeding bobbin supply device 1 includes a feeding device (reversing machine) 3, a transport conveyor (transport unit) 4, a separation transport conveyor 5, an orientation determination device 6, and a bobbin chute 7.

  The charging device 3 includes a movable frame 31 on which a wagon 60 that is a box-like body can be mounted. The wagon 60 includes a wheel on the bottom of a rectangular parallelepiped box that is open upward. Although only one is shown in FIG. 1, a large number of yarn feeding bobbins 10 are accommodated inside the wagon 60.

  The movable frame 31 includes two forks 32 that can support the bottom surface of the wagon 60 and guide plates 33 that guide both side surfaces of the wagon 60. The movable frame 31 is supported so as to be rotatable about a fulcrum. A cylinder 34 as an actuator is connected to the movable frame 31 (see FIG. 2). The cylinder 34 is configured as a backward-acting hydraulic cylinder, and the movable frame 31 can be rotated by driving the cylinder 34 to extend and contract.

  As shown in FIG. 2, the yarn feeding bobbin supply device 1 includes a closing control unit (actuator control unit) 90 that controls the rotation of the movable frame 31 by driving the cylinder 34. The input control unit 90 is configured as a microcomputer and includes a CPU, a ROM, a RAM, and the like (not shown). The input control unit 90 controls expansion and contraction of the cylinder 34 via an electromagnetic valve (not shown) for switching the supply of hydraulic oil.

  As shown in FIG. 2, a sensing lever 35 is rotatably supported at an appropriate position of the movable frame 31. A set sensor 36 that detects the rotation of the sensing lever 35 is disposed at the base of the sensing lever 35. This set sensor 36 is electrically connected to the making control unit 90.

  Although the sensing lever 35 has a posture protruding obliquely downward by the elastic force of a biasing spring (not shown) (see FIG. 3), when the wagon 60 is attached to the movable frame 31, the sensing lever 35 is moved to the position shown in FIG. The set sensor 36 detects the rotation of the sensing lever 35. Thereby, the making control unit 90 can detect the setting of the wagon 60 to the making device 3.

  An operation panel 37 is provided at an appropriate position on the front side of the yarn feeding bobbin supply device 1. On the operation panel 37, a raising switch 38 for raising the movable frame 31 is disposed. The raising switch 38 is configured as a push button switch with a built-in lamp, and the raising switch 38 itself can be illuminated. Further, the raising switch 38 is electrically connected to the making control unit 90, and the making control unit 90 can detect the operation of the raising switch 38 and can control lighting, extinguishing or blinking of the raising switch 38. it can.

  The conveyor 4 shown in FIGS. 1 and 2 is provided so as to connect the input device 3 and the separation conveyor 5. The transport conveyor 4 is configured as a vibration type conveyor, and includes a vibration motor 42 for vibrating the elongated transport surface 41. With this configuration, by driving the vibration motor 42 to vibrate the conveying surface 41, the yarn feeding bobbin 10 thrown from the feeding device 3 to the upstream side in the conveying direction of the conveying conveyor 4 is transferred to the separation conveying conveyor 5 on the downstream side. Can be transported.

  Elongated guide portions 44 that guide the yarn feeding bobbin 10 so as not to fall from the conveying surface 41 are provided on both sides of the conveying surface 41 so as to protrude upward from the height of the conveying surface 41. The guide portion 44 and the transport surface 41 constitute a bobbin receiving portion 45 that receives the yarn feeding bobbin 10 supplied from the wagon 60.

  A bobbin sensor (bobbin amount confirmation unit) 43 capable of detecting the presence or absence of the yarn feeding bobbin 10 is disposed in the bobbin receiving unit 45 (specifically, the guide unit 44) at the upstream end of the conveyor 4. ing. The bobbin sensor 43 is configured as a non-contact sensor having a light projecting unit and a light receiving unit. The light projecting unit and the light receiving unit are supported via a fixing structure (not shown), and the mounting height can be appropriately changed. Examples of the fixing structure include a structure including a bolt and a nut and a long hole that is long in the vertical direction, but is not limited thereto. Although details will be described later, the bobbin sensor 43 always checks the yarn feeding bobbin 10 on the bobbin receiving portion 45 in order to prevent the yarn supplying bobbin 10 exceeding the specified supply amount from being supplied to the bobbin receiving portion 45. Yes.

  The separation / conveyance conveyor 5 shown in FIG. 1 is configured as a vibration type conveyor like the conveyance conveyor 4. The separation / conveyance conveyor 5 includes a feeder bowl 51 formed in a bowl shape and a solenoid 52 for vibrating the feeder bowl 51. With this configuration, the solenoid 52 is driven to vibrate the feeder bowl 51, whereby the yarn feeding bobbins 10 fed into the feeder bowl 51 from the conveyor 4 are separated one by one and the downstream direction in the bobbin conveying direction It can be supplied to the discrimination device 6. In addition, you may make it the structure which drives the separation conveyance conveyor 5 using a motor instead of this solenoid 52. FIG.

  The direction discriminating device 6 includes a direction detection sensor (not shown) for discriminating the direction of the yarn feeding bobbin 10 and a direction changing lever (not shown) for changing the direction of the yarn feeding bobbin 10. When the direction detection sensor detects the direction of the supplied yarn supplying bobbin 10, the direction determining device 6 drives the direction changing lever as necessary to align the direction of the yarn supplying bobbin 10 at a constant level. It is dropped and supplied to the bobbin chute 7.

  The bobbin chute 7 sets the yarn supplying bobbin 10 supplied from the orientation determining device 6 so that the core of the yarn supplying bobbin 10 is inserted into the peg of the tray 11 for conveying the yarn supplying bobbin 10. The yarn supplying bobbin 10 thus mounted on the tray 11 is conveyed together with the tray 11 toward a plurality of winder units arranged in the automatic winder.

  Next, the feeding control of the yarn feeding bobbin 10 in the feeding control unit 90 of the present embodiment will be described with reference to the flowchart of FIG. FIG. 6 is a flowchart showing processing performed by the input control unit 90. It is assumed that the movable frame 31 is in a lowered state as shown in FIG. 3 when the processing of FIG. 6 is started.

  When the flow of FIG. 6 is started, the input control unit 90 determines whether or not the wagon 60 is set in the input device 3 by examining the state of the set sensor 36 (S101). If the wagon 60 is not set, the system waits until the wagon 60 is set.

  When it is determined in S101 that the wagon 60 is set in the input device 3 as shown in FIG. 4, the input control unit 90 blinks the lamp built in the ascent switch 38 (S102, FIG. 4). See also). Thereby, the operator can confirm by visually checking the state of the raising switch 38 that the yarn feeding bobbin 10 can be input to the conveyor 4 side. Thereafter, the making control unit 90 waits until the raising switch 38 is pushed by the operator (S103).

  When the operator presses the raising switch 38, the closing control unit 90 extends the cylinder 34, raises the wagon 60 together with the movable frame 31 (S104), and after a specified time has elapsed from the start of the movement of the wagon 60 (S105), the movable control unit 90 moves. The raising of the frame 31 is stopped, and the wagon 60 is stopped (S106). A state in which the movable frame 31 is raised for a specified time (ie, a state in which the movable frame 31 is inclined by a specified inclination amount) is shown by a solid line in FIG. It falls and is supplied to the upstream end of the conveyor 4. However, during the ascending operation of the movable frame 31 shown in S105, it is constantly monitored by the bobbin sensor 43 whether or not the yarn feeding bobbin 10 exceeding the specified supply amount is supplied to the conveyor 4 and before the specified time elapses. Even when a sufficient amount of the yarn feeding bobbin 10 is supplied from the wagon 60 to the conveyor 4, and the bobbin sensor 43 detects the yarn feeding bobbin 10, the raising of the movable frame 31 is stopped. Thereby, excessive supply of the yarn feeding bobbin 10 can be prevented. The specified supply amount of the yarn supplying bobbin 10 will be described in detail at S107.

  Thereafter, the closing control unit 90 causes the movable frame 31 to wait for a specified time in a state where the ascent is stopped (S106). In the following description, the predetermined time as the time during which the movable frame 31 is kept stationary may be referred to as the specified stationary time. The specified resting time can be arbitrarily determined, but after the yarn feeding bobbin 10 inside the wagon 60 collapses at the current inclination angle, the collapse of the yarn feeding bobbin 10 is settled, and the yarn feeding bobbin 10 in the wagon 60 It is preferable to define in consideration of the time until the state where the movement disappears. As a specific example, it can be considered to be 1 second or more and 3 seconds or less, preferably 2 seconds.

  Next, the loading control unit 90 checks the state of the bobbin sensor 43 installed at the upstream end of the conveyor 4 and determines whether the bobbin sensor 43 detects the yarn feeding bobbin 10 (S107). That is, when the remaining amount of the yarn feeding bobbin 10 in the wagon 60 is small from the beginning, the yarn feeding bobbin 10 is not actually put into the conveyor 4 at a gentle inclination as shown by the solid line in FIG. Alternatively, it is conceivable that the input amount becomes insufficient. Therefore, in this embodiment, the bobbin sensor 43 detects whether or not the yarn feeding bobbin 10 is actually supplied in a sufficient amount.

  Specifically, when the bobbin sensor 43 installed at a certain position higher than the conveyance surface 41 detects the yarn feeding bobbin 10, a pile of at least a certain size made up of the plurality of yarn feeding bobbins 10 is formed on the conveyance surface 41. Will be formed. Accordingly, in this case, the input control unit 90 determines that the amount of the yarn feeding bobbin 10 supplied to the transport conveyor 4 (bobbin receiving unit 45) satisfies the specified supply amount. On the other hand, when the bobbin sensor 43 does not detect the yarn feeding bobbin 10, the input control unit 90 determines that the amount of the yarn feeding bobbin 10 supplied to the transport conveyor 4 is less than the specified supply amount. Therefore, checking whether the bobbin sensor 43 has detected the yarn feeding bobbin 10 means that the amount of the yarn feeding bobbin 10 supplied to the conveyor 4 (bobbin receiving portion 45) is a predetermined supply amount (specified). This is equivalent to confirming whether or not it is equal to or greater than (supply amount). The specified supply amount can be adjusted as appropriate by changing the mounting height of the bobbin sensor 43.

  If the bobbin sensor 43 detects the yarn feeding bobbin 10 as a result of the determination in S107, it means that a sufficient amount of yarn feeding bobbin 10 has already been supplied to the conveyor 4 (bobbin receiving portion 45). Accordingly, the loading control unit 90 conveys the yarn feeding bobbin 10 to the downstream side by the conveyor 4 until the bobbin sensor 43 does not detect the yarn feeding bobbin 10 (in other words, the yarn feeding bobbin 10 on the bobbin receiving portion 45 The movable frame 31 is put on standby until the amount falls below the specified supply amount.

  If the bobbin sensor 43 has not detected the yarn feeding bobbin 10 as a result of the determination in S107, the supply control unit 90 starts to raise the movable frame 31 because the supply amount of the yarn feeding bobbin 10 is insufficient (S108). ). The raising of the movable frame 31 is continued until the specified time elapses or until the bobbin sensor 43 detects the yarn feeding bobbin 10 as in S105 (S109). As a result, the wagon 60 rises, for example, to the state of the chain line in FIG. 5, and the yarn feeding bobbin 10 staying inside the wagon 60 is urged to drop (inject) onto the conveyor 4. Subsequently, the closing control unit 90 stops the movable frame 31 in this state, and waits for a specified time (the specified still time) (S110).

  Thereafter, the closing control unit 90 checks the state of the bobbin sensor 43 again and determines whether the bobbin sensor 43 detects the yarn feeding bobbin 10 (S111). When the bobbin sensor 43 detects the yarn feeding bobbin 10, the input control unit 90 returns to the process of S <b> 111 and waits until the yarn feeding bobbin 10 is not detected by the bobbin sensor 43 due to the conveyance of the yarn feeding bobbin 10 by the conveyor 4. To do.

  On the other hand, if the bobbin sensor 43 does not detect the yarn feeding bobbin 10 as a result of the determination in S111, it is necessary to further tilt the wagon 60. Therefore, the making control unit 90 determines whether or not the current movable frame 31 is located at the rising end of the movable stroke of the movable frame 31 using an appropriate sensor (S112). If the movable frame 31 is not positioned at the ascending end, the making control unit 90 returns to the process of S108, raises the movable frame 31, and repeats the above process. If the movable frame 31 is already at the ascending end, the movable frame 31 cannot be further raised, so the closing control unit 90 notifies the operator of the closing completion by an appropriate method such as a lamp and stops the processing ( S113).

  According to the above flow, when the feeding device 3 lifts the wagon 60 and tilts it sideways as shown in FIG. 5 and stops it in this state (S104 to S106), and then the bobbin sensor 43 cannot detect the yarn feeding bobbin 10 ( When the yarn feeding bobbin 10 can no longer be detected due to the conveyance of the conveyance conveyor 4), the control of making the inclination of the wagon 60 more firm and stationary is repeated (loop of S <b> 108 to S <b> 112). As a result, the yarn feeding bobbins 10 can be fed into the conveyor 4 in small steps.

  Even if a sufficient amount of yarn supplying bobbin 10 remains in the wagon 60, depending on the situation of the yarn supplying bobbin 10, it takes time for the yarn supplying bobbin 10 to roll out from the lifted wagon 60. However, after a certain amount of time has passed, a phenomenon may occur in which the bobbin sensor 43 is detected by being loaded into the conveyor 4. This phenomenon is particularly likely to occur in the initial state where the wagon 60 starts to rise (a state where the inclination is gentle). However, in the present embodiment, before the bobbin sensor 43 detects the yarn feeding bobbin 10, processing is performed in which the movable frame 31 is stopped and waited for a specified time (S106, S110). Therefore, after waiting for a certain amount of time for the yarn feeding bobbin 10 to roll out of the wagon 60, the bobbin sensor 43 checks the presence or absence of the yarn feeding bobbin 10, so that excessive feeding of the yarn feeding bobbin 10 due to excessive inclination of the wagon 60 is performed. Can be prevented.

  As described above, the yarn feeding bobbin supply device 1 according to the present embodiment includes the wagon 60, the cylinder 34, the transport conveyor 4, the bobbin sensor 43, and the input control unit 90. The wagon 60 is open at the top and accommodates the yarn feeding bobbin 10. The cylinder 34 is driven to tilt the wagon 60. The conveyor 4 conveys the yarn feeding bobbin 10 supplied from the wagon 60 tilted by the cylinder 34. The bobbin sensor 43 always checks whether or not the amount of the yarn feeding bobbin 10 supplied to the conveyor 4 satisfies the specified supply amount. The input control unit 90 controls the cylinder 34. The closing control unit 90 drives the cylinder 34 (S104 / S108), tilts the wagon 60 by a specified inclination amount (S105 / S109), and after the wagon 60 is kept stationary for a specified stationary time (S106 / S110), It is confirmed whether or not the amount of the yarn feeding bobbin 10 on the conveyor 4 satisfies the prescribed supply amount (S107 / S111). If the amount of the yarn feeding bobbin 10 does not satisfy the prescribed supply amount, the cylinder 34 is driven. The wagon 60 is controlled to be further tilted (S108 to S109).

  As a result, the yarn feeding bobbins 10 can be fed into the conveyor 4 in small steps. Even if it takes a certain amount of time from when the wagon 60 is tilted to when the yarn feeding bobbin 10 is input to the conveyor 4, the inclination of the wagon 60 does not increase as long as the input is in time for the specified stationary time. . Accordingly, it is possible to prevent the wagon 60 from being tilted more than necessary and the excessive yarn feeding bobbin 10 from being fed into the conveying conveyor 4 at a time, so that smooth conveyance on the conveying conveyor 4 can be realized and yarn feeding can be achieved. Damage to the conveyor 4 due to the insertion of the bobbin 10 can be reduced.

  Further, in the yarn feeding bobbin supply device 1 of the present embodiment, the conveyor 4 includes a bobbin receiving portion 45 that receives the yarn feeding bobbin 10 supplied from the wagon 60. The bobbin sensor 43 checks whether or not the amount of the yarn feeding bobbin 10 supplied to the bobbin receiving portion 45 satisfies the specified supply amount.

  Thus, by checking the amount of the yarn feeding bobbin 10 supplied from the wagon 60 to the conveyor 4 and received by the bobbin receiving portion 45, it is possible to simply determine whether the amount of the yarn feeding bobbin 10 satisfies the specified supply amount. Can be confirmed in the configuration.

  Further, in the yarn feeding bobbin supply device 1 of the present embodiment, the bobbin sensor 43 is configured as a sensor that is provided on the bobbin receiving portion 45 (the guide portion 44) of the conveyor 4 and detects the presence or absence of the yarn feeding bobbin 10. . The specified supply amount is determined according to the mounting height of the bobbin sensor 43.

  Thereby, the specified supply amount can be easily adjusted by changing the mounting height of the bobbin sensor 43.

  Further, the yarn feeding bobbin supply device 1 of this embodiment includes a cylinder 34, a transport conveyor 4, and a bobbin sensor 43. The cylinder 34 is driven to tilt the wagon 60 that is open at the top and accommodates the yarn supplying bobbin. The conveyor 4 conveys the yarn feeding bobbin 10 that has come out of the inclined wagon 60. The bobbin sensor 43 confirms whether or not the amount of the yarn feeding bobbin 10 that has come out of the wagon 60 and is supplied to the conveyor 4 satisfies a specified supply amount. The yarn feeding bobbin supply device 1 is controlled as follows. That is, in the first step, the cylinder 34 is driven to tilt the wagon 60 (S104 to S105 / S108 to S109). In the second step, the wagon 60 is kept stationary for a specified stationary time (S106, S110). In the third step, the bobbin sensor 43 checks the amount of the yarn feeding bobbin 10 (S107 / S111). In the fourth step, as a result of confirmation by the bobbin sensor 43, when the yarn feeding bobbin 10 is less than the specified supply amount, the cylinder 34 is driven to further tilt the wagon 60 (S108 to S109).

  As a result, the yarn feeding bobbins 10 can be fed into the conveyor 4 in small steps. Even if it takes a certain amount of time from when the wagon 60 is tilted to when the yarn feeding bobbin 10 is put into the conveyor 4, the inclination of the wagon 60 does not increase as long as the specified stationary time is met. Accordingly, it is possible to prevent the wagon 60 from being tilted more than necessary and the excessive yarn feeding bobbins 10 from being loaded into the transport conveyor 4 at one time, so that smooth transport on the transport conveyor 4 can be realized.

  In this embodiment, as a result of the confirmation by the bobbin sensor 43, even when the yarn feeding bobbin 10 is less than the specified supply amount, the drive position of the cylinder 34 reaches the rising end as shown in S112 and S113. If so, the step of tilting the wagon 60 by driving the cylinder 34 (the fourth step) is not performed.

  As a result, the control for tilting the wagon 60 beyond the limit is prevented, so that the efficiency of the control can be realized.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  As an actuator for tilting the movable frame 31 and the wagon 60, for example, an electric motor or the like can be used instead of the cylinder 34.

  The conveyor 4 can be changed to a belt conveyor using an endless belt, for example, instead of the vibration type conveyor.

  Instead of detachably configuring the wheeled wagon 60, the storage box of the yarn feeding bobbin 10 can be fixed to the movable frame 31, and the storage box can be changed to rotate and tilt together with the movable frame 31. .

  The standby time (the prescribed rest time) in S106 and S110 of FIG. 6 can be a fixed time, or can be changed by an operator's operation. Also, the specified rest time can be changed according to the inclination of the box-shaped body. For example, in a state where the wagon 60 is tilted so as to be substantially upside down, the yarn feeding bobbin 10 inside the wagon 60 is surely dropped in a short time, so control is performed to shorten the stationary time. It is possible.

  In the processing of S105 and S109 in FIG. 6, when the movable frame 31 is raised, the raising control is performed based on the time, but the raising is performed based on the angle of the movable frame 31 or the wagon 60 or the extension amount of the cylinder 34 You may change so that control of this may be performed.

  The prescription in the present invention includes a numerical value included in a range that can be arbitrarily set by an operator.
