[0003] [Patent Document 1] JP 2012-184074 A [Patent Document 2] JP 2012-184075 A Summary of the Invention [Problem to be solved by the invention]

[0004] Depending on the momentum or posture of the yarn supplying bobbin (bobbin) supplied to the singulating section, the yarn supplying bobbin may not be placed on the upper side of the bobbin plate but may fall to the lower side of the bobbin plate. In this case, the yarn supplying bobbin may get under the bobbin plate, causing a blockage in the singulating section.

[0005] The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a supply device capable of suppressing clogging caused by the bobbins supplied to the singulation section entering under the support table.

[0006] The problem to be solved by the present invention has been described above. Next, the means for solving this problem and the effects thereof will be described.

[0007] According to an aspect of the present invention, a supplying device having the following configuration is provided. That is, the supplying device supplies a bobbin wound with a yarn produced by a spinning machine to a yarn winding machine. The supplying device includes a receiving unit and an individualizing unit. A plurality of the bobbins are input to the receiving unit. The individualizing unit separates the plurality of bobbins supplied from the receiving unit into individual bobbins and transports them upward. The individualizing unit includes a support table and a drive unit. The support table supports the bobbins and places the bobbins on the support table. The drive unit moves the support table in an up-down direction. The individualizing unit separates one or more of the bobbins by dropping them from the support table so that one bobbin is placed on the support table. In a plan view, a direction in which the bobbins are supplied from the receiving unit to the individualizing unit is a first direction, and a direction perpendicular to the first direction is a second direction. A slit is formed in the support table with the first direction as a longitudinal direction. The receiving section or the individualizing section has a guide section passing through the slit in an introduction area where the bobbin is placed on the support base. The support base picks up the bobbin guided by the guide section and places the bobbin on the support base.

[0008] In this way, since the bobbin is guided by the guide portion, the bobbin does not move below the support table when the bobbin is picked up and placed on the support table, and therefore clogging of the singulation section can be suppressed.

[0009] The supply device is preferably configured as follows. That is, the guide section is provided in the receiving section. The individualizing section is provided along a transport direction in which the support table transports the bobbins, and has a separating member that drops and separates one or more of the bobbins from the support table so that one of the bobbins is placed on the support table. The guide section and the separating member are separate bodies. The separating member and the guide section pass through one of the slits.

[0010] With this, since the guide portion and the separating member are separate bodies, a complicated structure such as welding can be avoided.

[0011] The supply device is preferably configured as follows: the supply device includes a sensor that detects that the bobbins are clogged in the singulation unit, and when the sensor detects the clog, the drive unit moves the support table a distance smaller than the vertical arrangement interval of the support table in a direction opposite to normal movement.

[0012] This allows the blockage to be cleared even if the individualizing section becomes clogged.

[0013] The supply device is preferably configured as follows: the supply device includes a sensor that detects that the bobbin is clogged in the singulation unit, and the drive unit moves the support table by 50 mm to 120 mm in a direction opposite to normal when the sensor detects the clog.

[0014] This allows the bobbin to be moved an appropriate distance taking into account the axial length of the bobbin, thereby clearing blockages in the individualizing section.

[0015] The supplying device is preferably configured as follows. That is, the supplying device includes a detection unit and a transport unit. The detection unit detects that the bobbin is clogged in the singulation unit. The transport unit transports the bobbin transported by the singulation unit to a next process. When the sensor detects the clog, the transport unit returns the bobbin from the transport unit directly to the receiving unit.

[0016] This makes it possible to prevent problems caused by clogging of the individualizing section.

[0017] In the supply device, it is preferable that the guide portions are arranged in the second direction in a number of 4 to 9.

[0018] This prevents the bobbin from moving below the support table even when the bobbin is picked up so that it is positioned at various positions in the second direction.

[0019] The supply device is preferably configured as follows: That is, the slits and the guide portions are arranged in a plurality of positions in the second direction. In the second direction, the distance between the guide portions is 25 mm or more and 60 mm or less. In the supply device, the length of the guide portions in the up-down direction is preferably 50 mm or more and 150 mm or less.

[0020] This allows for an appropriately sized feeder that takes into account standard bobbin sizes.

[0021] In the supplying device, it is preferable that the drive unit is a stepping motor.

[0022] As a result, even if the individualizing section becomes clogged, the stepping motor will step out, preventing damage to the individualizing section, etc. [Brief description of the drawings]

[0024] Next, an embodiment of the present invention will be described with reference to the drawings.

[0025] First, an overview of the supplying device 1 will be described with reference to Figures 1 and 2. In the following description, the upstream and downstream in the direction in which the bobbin 91 is transported will simply be referred to as upstream and downstream.

[0026] The supplying device 1 supplies a bobbin 91 to a yarn winding machine such as an automatic winder. The bobbin 91 is a yarn supplying bobbin formed by winding yarn produced by a spinning machine around a core tube. The yarn winding machine winds the yarn wound around the bobbin 91 to form a package. As shown in FIG. 1, the supplying device 1 includes a receiving unit 10, an individualizing unit 20, a setting unit 30, and a control device 40.

[0027] 1 accommodates a plurality of bobbins 91 formed by a spinning machine. The accommodation body 90 is a box-shaped member with an opening formed on the upper side. The accommodation body 90 is tilted by an operator or an unillustrated loading device so that the opening faces downward, whereby the plurality of bobbins 91 accommodated in the accommodation body 90 are loaded into the receiving section 10.

[0028] The receiving section 10 has a retention section 11, a limiting section 12, and an inclined section 13. The bobbins 91 inserted from the container 90 are temporarily retained in the retention section 11. The retention section 11 has an inclined surface that decreases in height toward the downstream side, and the bobbins 91 can be transported by their own weight. Note that the bobbins 91 may be transported by a conveyor instead of the inclined surface.

[0029] The limiting section 12 is provided between the accumulating section 11 and the inclined section 13 in the transport direction of the bobbin 91. The limiting section 12 is capable of moving up and down. As the limiting section 12 moves up and down, the limiting section 12 changes its position between an elevated state and a lowered state. While the limiting section 12 is in the elevated state, the movement of the bobbin 91 is prevented. While the limiting section 12 is in the lowered state, the movement of the bobbin 91 is permitted. In addition, as the limiting section 12 switches between the elevated state and the lowered state at a predetermined timing, the supply amount of the bobbin 91 from the accumulating section 11 to the inclined section 13 can be adjusted.

[0030] The inclined section 13 has an inclined surface that decreases in height toward the downstream side. The inclined section 13 transports the bobbin 91 by its own weight. The bobbin 91 moves by rolling or sliding down the inclined section 13 in a fallen state and is supplied to the individualizing section 20. The state in which the bobbin 91 is in a fallen state means that the bobbin 91 is not standing upright relative to the transport surface (inclined surface, etc.) and the axial direction of the bobbin 91 is parallel or approximately parallel to the transport surface.

[0031] As shown in FIG. 2, in a plan view, the direction in which the retention section 11 transports the bobbin 91 and the direction in which the inclined section 13 transports the bobbin 91 are perpendicular to each other. However, these directions may intersect at an angle other than 90 degrees, or may be the same. In the following description, the direction in which the inclined section 13 transports the bobbin 91 (particularly, the direction in which the inclined section 13 supplies the bobbin 91 to the individualizing section 20) in a plan view is referred to as a first direction. In addition, a direction perpendicular to the first direction in a plan view is referred to as a second direction. In this embodiment, the direction in which the retention section 11 transports the bobbin 91 and the second direction are the same, but they may be different.

[0032] The individualizing unit 20 separates the multiple bobbins 91 supplied from the inclined portion 13 of the receiving unit 10 into individual bobbins 91 and transports them upward one by one. The bobbins 91 transported by the individualizing unit 20 are transported to the setting unit 30 via the transport unit 50. The individualizing unit 20 will be described in detail later.

[0033] The setting unit 30 sets the bobbins 91 supplied from the individualizing unit 20 on a tray 92. The tray 92 is movable along a transport path 93 formed by a conveyor or the like. The bobbins 91, while being set on the tray 92, move along the transport path 93 and are supplied to the yarn winding machine.

[0034] The control device 40 includes a calculation device such as a CPU, a RAM, and a storage. The storage is an HDD, an SSD, a flash memory, or the like. The storage stores a program related to the supply device 1 and data such as conditions required for executing the program. The calculation device reads the program stored in the storage into the RAM and executes it. In this way, the control device 40 performs various controls related to the restriction unit 12, the individualization unit 20, and the setting unit 30.

[0035] Next, the individualizing unit 20 will be described in detail with reference to FIGS.

[0036] The individualizing unit 20 has a conveyor composed of a belt 21, two rotating rollers 22 arranged above and below, and a drive unit 23. The belt 21 is a band-shaped (sheet-shaped) member. The belt 21 is looped around the two rotating rollers 22. The upper rotating roller 22 is driven to rotate by the drive unit 23. In this embodiment, the drive unit 23 is a stepping motor. The rotation of the output shaft of the stepping motor is transmitted to the upper rotating roller 22 via a drive transmission belt or the like. As a result, the belt 21 is driven to circulate in the vertical direction.

[0037] Support tables 25 are provided on the outer surface of belt 21. The support tables 25 are provided at equal intervals in the longitudinal direction of belt 21. The support tables 25 move vertically together with belt 21. A bobbin 91 is placed on the support table 25. As a result, the support table 25 supports the bobbin 91 placed thereon and transports the bobbin 91. The support table 25 has a rectangular surface so that the bobbin 91 in a fallen state can be placed on it. This rectangular support table 25 is attached to belt 21 such that its longitudinal direction is aligned with the width direction of belt 21.

[0038] 4 and 5, a slit 26 is formed in the support base 25 in a direction along the depth direction (first direction). A plurality of slits 26 are formed in the longitudinal direction of the support base 25. A separating member 27 passes through each of the plurality of slits 26. The separating member 27 is, for example, a metal wire. However, the separating member 27 is not limited to a metal wire.

[0039] As shown in FIG. 4, the end 25a in the longitudinal direction of the support table 25 is located outside the area in which the bobbin 91 is transported. The individualizing unit 20 includes a belt sensor (detection unit) 28 that detects the end 25a. The belt sensor 28 is attached to the frame of the individualizing unit 20, not to the belt 21. The belt sensor 28 is, for example, a contact sensor or a non-contact sensor (such as a magnet sensor or an optical sensor). The belt sensor 28 transmits the detection result to the control device 40. When the belt 21 is driven, the end 25a moves together with the belt 21, but the position of the belt sensor 28 does not change. Therefore, when the belt 21 is driven, the belt sensor 28 alternately detects and does not detect the end 25a. However, when a blockage occurs in the individualizing unit 20, the detection result of the belt sensor 28 does not change even though the belt 21 is driven. In other words, the belt sensor 28 either maintains a state in which it continues to detect the end 25a, or maintains a state in which it does not detect the end 25a. When the drive unit 23 is operating and the detection result of the belt sensor 28 does not change within the threshold time, the control device 40 determines that there is a blockage in the individualizing unit 20. The detection unit that detects a blockage in the individualizing unit 20 is not limited to the belt sensor 28. For example, the detection unit may be a calculation device that refers to the load on the drive unit 23 and determines that a blockage has occurred in the individualizing unit 20 if the load is greater than a threshold.

[0040] As shown in FIG. 3, the individualizing unit 20 is divided into an introduction area, a separation area, and a transport area in the ascending area where the bobbins 91 ascend, in that order from the downstream side. The introduction area is an area for placing the bobbins 91 supplied from the receiving unit 10 on the support table 25. The separation area is an area for dropping and separating the other bobbins 91 so that one bobbin 91 is placed on the support table 25 when multiple bobbins 91 are placed on the support table 25 in the introduction area. The transport area is an area for transporting the bobbins 91 toward the setting unit 30 in a state where one bobbin 91 is placed on the support table 25 in the separation area. The separation member 27 has a first member 61 located in the introduction area, a third member 63 located in the separation area, and a second member 62 located in the transport area. The separation member 27 also has a fourth member for dropping the bobbins 91 placed on the support table 25 and transporting them to the transport unit 50.

[0041] 3 and 5, the downstream end of the inclined section 13 is adjacent to the introduction area of ​​the individualizing section 20. The bobbin 91 moved by the inclined section 13 under its own weight is thrown into the introduction area of ​​the individualizing section 20 while the belt 21 is driven. As a result, the bobbin 91 is thrown between the support tables 25 arranged vertically. Since the support table 25 is moving upward, the bobbin 91 is scooped up by the support table 25. As a result, one or more bobbins 91 are placed on the support table 25.

[0042] Here, in the conventional supply device, depending on the timing at which the bobbin 91 is inserted, there is a possibility that the bobbin 91 may enter the space 20a present below the guide unit 14. If the bobbin 91 enters the space 20a and the support base 25 is unable to scoop up the bobbin 91 because the bobbin 91 gets caught somewhere, a blockage occurs in the individualizing unit 20. To prevent this type of blockage, the receiving unit 10 is provided with the guide unit 14 shown in Figs. 3 and 5. The space 20a also includes a space partitioned by a wall (floor) covering the lower part of the conveyor.

[0043] A part of the guide portion 14 (specifically, the upper surface) is located in the introduction area. Furthermore, the guide portion 14 is a plate-like member that guides the bobbin 91 guided by the inclined portion 13 and before it is picked up by the support base 25. The guide portion 14 in this embodiment is separate from the separation member 27. The guide portion 14 guides the bobbin 91 with the side surface (surface parallel to the thickness direction) of the plate. The guidance by the guide portion 14 means that the position of the bobbin 91 is restricted so that the bobbin 91 does not enter the space 20a. Therefore, the bobbin 91 supplied by the inclined portion 13 toward the individualizing portion 20 is guided by the guide portion 14, and the bobbin 91 guided by the guide portion 14 is picked up by the support base 25.

[0044] The guide portion 14 is connected to the inclined portion 13 and is configured to be immovable. At least a part of the guide portion 14 passes through the slit 26 of the support base 25. In addition, the support base 25 has a plurality of slits 26 aligned in the second direction. Meanwhile, a plurality of guide portions 14 are provided aligned in the second direction. Then, one guide portion 14 enters one slit 26. By inserting the guide portion 14 into the slit 26, it becomes possible to scoop up the bobbin 91 on the guide portion 14 by the support base 25 while preventing physical interference between the guide portion 14 and the support base 25. In addition, in the introduction area, the support base 25 may scoop up a plurality of bobbins 91, so that the plurality of bobbins 91 are placed on the support base 25.

[0045] Similarly to the inclined portion 13, the upper surface of the guide portion 14 is an inclined surface whose height decreases toward the downstream side. This allows the bobbin 91 that has reached the guide portion 14 from the inclined portion 13 to be guided further downstream. The first member 61 of the separation member 27 is also located in the slit 26. The support base 25 picks up the bobbin 91 in the range from the first member 61 to the tip of the support base 25 in the first direction. The tip of the support base 25 is the end of the support base 25 on the upstream side (the inclined portion 13 side) in the first direction. In other words, the first member 61 has a function of defining the range of the support base 25 in the introduction area where the bobbin 91 can be placed. The first member 61 also functions as a stopper to prevent the bobbin 91 from moving too far downstream and hitting the belt 21. In other words, the guide portion 14 and the separation member 27 (first member 61) can hold the bobbin 91 at a position where the support base 25 can pick it up.

[0046] The above-mentioned configuration of the guide section 14 is an example, and can be modified as follows. First, the guide section 14 may be a member on the individualizing section 20 side. For example, the guide section 14 may be fixed to the wall section covering the lower side of the belt 21 or to the separating member 27 by welding or the like. Alternatively, the guide section 14 may be configured by making the separating member 27 protrude toward the inclined section 13 side. Also, it is not essential that the guide section 14 is inserted into all the slits 26, and there may be slits 26 into which the guide section 14 is not inserted. Also, the guide section 14 is not limited to being plate-shaped, and may be block-shaped as long as it does not interfere with the support base 25.

[0047] In the separation region, the third member 63 of the separation member 27 comes into contact with the bobbin 91, so that one or more bobbins 91 are dropped from the support base 25 so that only one bobbin 91 is placed on the support base 25. As shown in FIG. 3, the third member 63 has a shape that protrudes toward the tip side (upstream side in the first direction). Specifically, the third member 63 has a first protruding portion 63a and a second protruding portion 63b. The second protruding portion 63b is provided above the first protruding portion 63a (i.e., downstream side). The shape of the first protruding portion 63a is different from the shape of the second protruding portion 63b. Specifically, the length La of the portion of the first protruding portion 63a parallel to the vertical direction is shorter than the length Lb of the portion of the second protruding portion 63b parallel to the vertical direction.

[0048] As shown in FIG. 6, when the bobbin 91 carried on the support table 25 approaches the position of the first protrusion 63a, it is pushed toward the tip side of the support table 25 by the first protrusion 63a. For example, when two bobbins 91 are placed on one support table 25 one above the other, the two bobbins 91 are pushed by the first protrusion 63a, causing the posture of the upper bobbin 91 to collapse. As a result of the collapse of the posture, the upper bobbin 91 may fall off the support table 25. Even if the bobbin 91 does not fall off the support table 25, the two bobbins 91 may be aligned along the first direction. After that, when the two bobbins 91 carried on the support table 25 approach the position of the second protrusion 63b, they are pushed toward the tip side of the support table 25 by the second protrusion 63b. As a result, the bobbin 91 located at the tip side of the two bobbins 91 aligned in the first direction can be dropped downward with a high probability. In addition, since the first protrusion 63a and the second protrusion 63b have different shapes (specifically, the length Lb is longer than the length La), the first protrusion 63a and the second protrusion 63b apply different forces to the bobbins 91. Therefore, for example, even if the two bobbins 91 are pushed by the first protrusion 63a and the bobbins 91 do not fall or change their arrangement, one bobbin 91 may fall from the support base 25 due to the second protrusion 63b pushing the bobbin 91.

[0049] In this way, the third member 63 has two protruding parts, and the shorter first protruding part 63a causes unnecessary bobbins 91 to fall by disrupting their posture. Even if the bobbins 91 do not fall, the second protruding part 63b can drop one bobbin 91. This allows only one of the two bobbins 91 placed on the support base 25 to be dropped accurately.

[0050] The shape of the third member 63 in this embodiment is an example, and can be changed, for example, as follows. The number of protrusions is not limited to two, but may be one or three. The first protrusion 63a and the second protrusion 63b are not limited to linear shapes, but may include curved shapes. The length La and the length Lb may be the same, or the length La may be longer than the length Lb. The first protrusion 63a and the second protrusion 63b may have the same shape.

[0051] In the transport area, the second member 62 of the separating member 27 is located in the slit 26. The second member 62 has a function of defining a range of the support table 25 on which the bobbin 91 can be placed in the transport area. That is, the transport of the bobbin 91 by the support table 25 in the transport area is performed in the range from the third member 63 to the tip of the support table 25 in the first direction.

[0052] 3, a contact sensor 71 is provided in the transport area. The contact sensor 71 is a contact-type sensor that detects the bobbin 91 transported by the support table 25. The contact sensor 71 is provided at a position that passes through the slit 26, and does not contact the support table 25, but does contact the bobbin 91 placed on the support table 25. The contact sensor 71 transmits the detection result of the bobbin 91 to the control device 40.

[0053] The number of slits 26, separating members 27, and guide parts 14 provided is not particularly limited. However, in order to enable the separating members 27 and guide parts 14 to come into contact with the bobbin 91 regardless of the position or posture of the bobbin 91, it is preferable that the separating members 27 and guide parts 14 are arranged in the first direction in a number between 4 and 9. When one separating member 27 and one guide part 14 are provided in one slit 26 as in this embodiment, it is also preferable that the number of slits 26 provided is between 4 and 9.

[0054] The bobbins 91 transported one by one by the singulating unit 20 are transported to the setting unit 30 via the transport unit 50. As shown in FIG. 4, the transport unit 50 has a conveyor 51, a bobbin sensor 52, and an opening 53.

[0055] The conveyor 51 is driven by power generated by a drive unit (not shown). The conveyor 51 transports the bobbin 91 toward the setting unit 30. The bobbin sensor 52 detects whether or not the bobbin 91 is present in the transport unit 50. The bobbin sensor 52 transmits the detection result of the bobbin 91 to the control device 40. The bobbin sensor 52 is, for example, an optical sensor, but may be another sensor. The opening 53 is an opening formed on the upstream side of the transport unit 50 in the transport direction. The opening 53 is a size that allows the bobbin 91 to pass through. The inclined unit 13 is located below the opening 53. The opening 53 is used to return the bobbin 91 to the inclined unit 13 when a blockage occurs in the individualizing unit 20.

[0056] Next, the process performed by the control device 40 in response to clogging of the individualizing section 20 will be described with reference to FIG.

[0057] The control device 40 acquires the detection results of the belt sensor 28 and the bobbin sensor 52 (S101). The control device 40 determines whether or not there is a blockage in the individualizing unit 20, as described above, based on the detection result of the belt sensor 28. When the control device 40 determines that there is a blockage in the individualizing unit 20, it controls the drive unit 23 of the individualizing unit 20 to drive the belt 21 in the reverse direction a predetermined length (S103). Here, the reverse direction means a direction opposite to that during normal conveyance in the individualizing unit 20.

[0058] The clogging of the individualizing unit 20 occurs, for example, when the bobbin 91 gets caught on the support base 25 or the like and cannot be removed. Since the driving unit 23 in this embodiment is a stepping motor, it will step out when a load of a certain level or more is applied, and the driving unit 23 and the support base 25 will not be damaged. In addition, by driving the belt 21 in the reverse direction, the bobbin 91 may be released from being caught. In addition, the predetermined length is preferably shorter than the interval D1 (FIG. 3), which is the arrangement interval of the support base 25 in the vertical direction (longitudinal direction of the belt 21). If the predetermined length is longer than the arrangement interval of the support base 25 in the vertical direction, the bobbin 91 that has entered under the support base 25 may be newly caught. Furthermore, if the predetermined length is too long, the bobbin 91 may be pinched between the guide unit 14 and the support base 25. Considering the interval D1 or other conditions, the predetermined length is preferably 50 mm or more and 120 mm or less.

[0059] Next, the control device 40 judges whether or not the bobbin 91 is present in the conveying section 50 based on the detection result of the bobbin sensor 52 (S104). If the conveying section 50 starts conveying the bobbin 91 with the bobbin 91 present in the conveying section 50, a state in which multiple bobbins 91 are present in the conveying section 50 may occur. Therefore, when the control device 40 judges that the bobbin 91 is present in the conveying section 50, it controls the drive section (not shown) of the conveying section 50 to drive the conveyor 51 in the reverse direction for a predetermined length (S105). Here, the reverse direction means the direction opposite to the normal conveying direction of the conveying section 50. By driving the conveying section 50 in the reverse direction, the bobbin 91 can be dropped from the opening 53 and the bobbin 91 can be returned directly (i.e., without passing through the individualizing section 20) to the inclined section 13.

[0060] Thereafter, the control device 40 controls the drive unit 23 of the individualizing unit 20 to drive the belt 21 in the normal conveying direction (S106). This causes the individualizing unit 20 to resume individualizing and conveying the bobbins 91 (S106). The control device 40 may again determine whether the clogging in the individualizing unit 20 has been cleared. That is, after step S105, the control device 40 may perform the process of step S106 when it is determined that there is no clogging in the individualizing unit 20, which is determined in the same manner as in step S102.

[0061] The flowcharts shown in the above embodiment are merely examples, and some processes may be omitted, some processes may be changed, or new processes may be added. For example, the processes in steps S104 and S105 may be omitted.

[0062] Next, the preferred length of each part of the individualizing section 20 will be described.

[0063] First, the height H1 of the guide portion 14 will be described with reference to FIG. 3. The height H1 of the guide portion 14 is the length from the lower end to the upper end in the vertical direction. If the height H1 is too short, the space 20a below the guide portion 14 becomes large, and the bobbin 91 may enter the space 20a. Furthermore, if the height H1 is too short, the bobbin 91 may move in the second direction and downward, and the bobbin 91 may enter the space 20a. On the other hand, if the height H1 is too long, the bobbin 91 cannot move in the second direction and downward, and it becomes difficult for the bobbin 91 to enter the space 20a. In order for the bobbin 91 to enter the space 20a, the bobbin 91 needs to move only downward between the guide portions 14. In other words, the axial direction of the bobbin 91 needs to be parallel to the vertical direction, and it becomes difficult for the bobbin 91 to enter the space 20a. Also, taking into consideration the size of the bobbin 91 and the interval D1 between the support bases 25, etc., it is not necessary to make the height H1 too large. Taking all of the above into consideration, it is preferable that the height H1 be 50 mm or more and 150 mm or less. However, the height H1 may be outside this range.

[0064] Next, the interval D2 will be described with reference to FIG. 5. The interval D2 is the interval between the guide parts 14 in the second direction. If the interval between the guide parts 14 is too wide, the bobbin 91 may fall between the guide parts 14 and reach the space 20a. On the other hand, if the interval between the guide parts 14 is too narrow, a large number of guide parts 14 are required, which increases the cost. Furthermore, if the interval between the guide parts 14 is too narrow, the part of the support base 25 that supports the bobbin 91 becomes thin. Furthermore, since the number of slits 26 increases, the cost required for processing increases and the strength of the support base 25 may decrease. Furthermore, if the thickness of the guide parts 14 is increased to prevent the bobbin 91 from falling between the guide parts 14, the cost of the material increases and the slits become larger, which reduces the function of scooping up the bobbin 91. Considering the above circumstances comprehensively, the interval D2 is preferably 25 mm or more and 60 mm or less. The interval D2 may be outside this range.

[0065] As described above, the supplying device 1 supplies the bobbins 91 wound with yarn produced by a spinning machine to the yarn winding machine. The supplying device 1 includes a receiving unit 10 and an individualizing unit 20. A plurality of bobbins 91 are fed into the receiving unit 10. The individualizing unit 20 separates the plurality of bobbins 91 supplied from the receiving unit 10 into individual bobbins 91 and transports them upward. The individualizing unit 20 includes a support table 25 and a driving unit 23. The support table 25 supports the bobbins 91 on which the bobbins 91 are placed. The driving unit 23 moves the support table 25 in the vertical direction. The individualizing unit 20 separates one or more bobbins 91 by dropping them from the support table 25 so that one bobbin 91 is placed on the support table 25. In a plan view, the direction in which the bobbins 91 are supplied from the receiving unit 10 to the individualizing unit 20 is a first direction, and the direction perpendicular to the first direction is a second direction. A slit 26 having a longitudinal direction in the first direction is formed in the support base 25. The receiving unit 10 or the individualizing unit 20 has a guide portion 14 passing through the slit 26 in an introduction area where the bobbin 91 is placed on the support base 25. The support base 25 scoops up the bobbin 91 guided by the guide portion 14 and places the bobbin 91 on the support base 25.

[0066] As a result, the bobbin 91 is guided by the guide portion 14, so that when the bobbin is picked up and placed on the support base 25, the bobbin 91 does not move below the support base 25. Therefore, clogging of the singulating section 20 can be suppressed.

[0067] In the supply device 1 of this embodiment, the guide unit 14 is provided in the receiving unit 10. The individualizing unit 20 is provided along the conveying direction in which the support table 25 conveys the bobbins 91, and has a separating member 27 that drops and separates one or more bobbins 91 from the support table 25 so that one bobbin 91 is placed on the support table 25. The guide unit 14 and the separating member 27 are separate bodies. The separating member 27 and the guide unit 14 pass through one slit 26.

[0068] As a result, the guide portion 14 and the separating member 27 are separate, and therefore a complicated structure such as welding can be avoided.

[0069] The supply device 1 of this embodiment includes a belt sensor 28 that detects that a bobbin 91 is stuck in the individualizing unit 20. When the belt sensor 28 detects a jam, the drive unit 23 moves the support table 25 in the opposite direction to the normal direction by a distance smaller than the vertical arrangement interval of the support table 25.

[0070] This allows the clogging to be cleared even if the individualizing section 20 becomes clogged.

[0071] The supply device 1 of this embodiment includes a belt sensor 28 that detects that a bobbin 91 is stuck in the individualizing unit 20. When the belt sensor 28 detects a jam, the drive unit 23 moves the support base 25 by 50 mm or more and 120 mm or less in the opposite direction to the normal direction.

[0072] This allows the bobbin 91 to be moved an appropriate distance taking into account its axial length, thereby clearing clogging in the individualizing section 20.

[0073] The supply device 1 of this embodiment includes a belt sensor 28 and a conveying unit 50. The belt sensor 28 detects that a bobbin 91 has become clogged in the individualizing unit 20. The conveying unit 50 conveys the bobbin 91 conveyed by the individualizing unit 20 to the next process. When the belt sensor 28 detects a clog, the conveying unit 50 returns the bobbin 91 from the conveying unit 50 directly to the receiving unit 10.

[0074] This makes it possible to prevent problems caused by clogging of the individualizing section 20.

[0075] In the supply device 1 of the present embodiment, 4 to 9 guide portions 14 are provided and aligned in the second direction.

[0076] As a result, even if the bobbin 91 is positioned at various positions on the support table 25 in the second direction, the bobbin 91 does not move below the support table 25.

[0077] In the supply device 1 of this embodiment, a plurality of slits 26 and guide portions 14 are arranged in the second direction. In the second direction, the interval D2 between the guide portions 14 is 25 mm or more and 60 mm or less. Moreover, the height H1 in the vertical direction of the guide portions 14 is 50 mm or more and 150 mm or less.

[0078] This makes it possible to realize a supplying device 1 of an appropriate size that takes into account the size of a standard bobbin 91.

[0079] In the supply device 1 of the present embodiment, the drive unit 23 is a stepping motor.

[0080] As a result, even if clogging occurs in the individualizing unit 20, the stepping motor will step out, preventing damage to the individualizing unit 20 and other components. [Explanation of symbols]
