[0003] [Patent Document 1] JP 2013-6669 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a configuration in which the bobbin is guided by a guide plate as in Patent Document 1, if there is a point where the width narrows as the bobbin approaches the downstream in the transport direction, the forces between the bobbins on both sides toward the inside in the width direction may become balanced, causing the bobbin to become clogged.

[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 supplying device in which bobbins are less likely to become clogged at a location where the width of the bobbin conveying surface becomes narrow.

[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 supply device having the following configuration is provided. That is, the supply device includes a conveying device and an input device. The conveying device conveys a bobbin wound with a thread. The input device inputs the bobbin from a container in which the bobbin is housed into the conveying device. The input device has a conveying surface and a guide section. The bobbin input from the container to the conveying device flows and is conveyed on the conveying surface. The guide section is provided to rise from the conveying surface and guides the bobbin. The conveying surface has a shape that becomes lower as it approaches the downstream of the conveying direction in which the bobbin is conveyed. The guide section includes a first inclined guide and a second inclined guide. The first inclined guide is located on a first side from the center of the conveying surface in a width direction perpendicular to the conveying direction on the conveying surface, and has an inclined surface that moves the bobbin inward in the width direction. The second inclined guide is located on a second side from a center in the width direction of the conveying surface in the width direction and has an inclined surface that moves the bobbin inward in the width direction. The inclined surfaces of the first inclined guide and the second inclined guide are provided at positions that only partially overlap in the conveying direction or at completely different positions.

[0008] As a result, the ranges in which the first and second inclined guides are provided do not coincide in the transport direction, which makes it difficult to balance the forces acting on the bobbins inward in the width direction, and therefore makes it difficult for the bobbins transported on the transport surface to become clogged.

[0009] In the above-mentioned supply device, it is preferable that the distance in the conveying direction between the downstream end of the inclined surface of the first inclined guide and the downstream end of the inclined surface of the second inclined guide in the conveying direction is 50 mm or more and 240 mm or less.

[0010] This makes it possible to maintain the minimum length necessary to prevent bobbin clogging while preventing the device size from becoming excessively large.

[0011] The above-mentioned supply device is preferably configured as follows. That is, the first inclined guide has a first member and a second member. The second member is disposed downstream of the first member in the conveying direction. When the first member and the second member are projected onto the conveying surface, the angle at which the inclined surface of the first member is inclined with respect to the conveying direction is different from the angle at which the inclined surface of the second member is inclined with respect to the conveying direction.

[0012] In this way, by using two members with inclined surfaces having different angles, it becomes easier to achieve both the effect of preventing bobbin clogging from occurring and the effect of preventing the device size from becoming excessive.

[0013] In the above-mentioned supply device, when the second member and the second inclined guide are projected onto the conveying surface, it is preferable that the angle at which the inclined surface of the second member is inclined with respect to the conveying direction is greater than the angle at which the inclined surface of the second inclined guide is inclined with respect to the conveying direction.

[0014] The angle of the inclined surface of the second member is large, so that the length of the first inclined guide in the conveying direction is reduced. Therefore, the length of the area in the conveying direction where the first inclined guide is not provided and the second inclined guide is provided can be increased. This makes it even more difficult for bobbins to become clogged.

[0015] The above-mentioned supply device is preferably configured as follows. That is, when the first member and the second member are projected onto the conveying surface, the angle at which the inclined surface of the first member is inclined with respect to the conveying direction is smaller than the angle at which the inclined surface of the second member is inclined with respect to the conveying direction. The second member has a space capable of accommodating a part of the first member. The first member is movable relative to the second member so as to enter the space of the second member.

[0016] This makes it possible to change the shape or size of the first inclined guide by moving the first member relative to the second member.

[0017] In the supply device, it is preferable that, when the second member is projected onto the transport surface, the length of the inclined surface of the second member is not less than 80 mm and not more than 200 mm.

[0018] This makes it possible to appropriately guide the bobbin inward in the width direction while preventing the device size from becoming excessively large.

[0019] The above-mentioned supply device is preferably configured as follows. That is, the input device includes a rotating part that rotates integrally with the conveying surface with the horizontal direction as the center of rotation. The rotation of the rotating part changes the position of the input device between a preparation position and an input position. The preparation position is a position for setting the container. The input position is a position in which the height of the conveying surface decreases as it approaches downstream in the conveying direction.

[0020] This makes it possible to prevent bobbins from becoming clogged when the loading device is changed from the preparation position to the loading position. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Next, an embodiment of the present invention will be described with reference to the drawings.

[0023] First, an overview of the supplying device 1 will be described with reference to Fig. 1 to Fig. 3. The supplying device 1 is a device that supplies a bobbin 91 having a thread wound around a core tube. The bobbin supplied by the supplying device 1 is supplied to a thread winding machine such as an automatic winder. The thread winding machine winds the thread wound around the bobbin to form a package. As shown in Fig. 1, the supplying device 1 includes an input device 2, a control device 3, and a conveying device 4.

[0024] A container 90 shown in Fig. 2 is set in the insertion device 2. The container 90 has a bottom and a plurality of side surfaces extending upright from the bottom, and a storage space is formed therein. A bobbin 91 is stored in the storage space of the container 90.

[0025] The insertion device 2 includes a rotating unit 11, a rotating shaft 12, and a motor 13. The rotating unit 11 is rotatably supported by the rotating shaft 12. The axial direction of the rotating shaft 12 is parallel to the horizontal direction. The motor 13 is an electric motor, and generates power based on a command from the control device 3. The rotating unit 11 rotates due to the power generated by the motor 13.

[0026] A first frame 14, a second frame 15, a conveying surface 16, and a guide portion 17 are fixed to the rotating portion 11. The first frame 14, the second frame 15, the conveying surface 16, and the guide portion 17 rotate integrally with the rotating portion 11. A container 90 is set on the first frame 14 and the second frame 15. The conveying surface 16 is a surface for conveying the bobbins 91 supplied from the container 90 toward the conveying device 4. The guide portion 17 guides the bobbins 91 flowing on the conveying surface 16.

[0027] As the rotating part 11 rotates, the posture of the feeding device 2 is changed between a preparation posture and a feeding posture. The preparation posture is a posture for setting the container 90 in the first frame 14 and the second frame 15. The feeding posture is a posture for feeding the bobbin 91. In the feeding posture, the height of the conveying surface 16 decreases toward the downstream side in the conveying direction, so that the bobbin 91 flows along the conveying surface 16 by its own weight.

[0028] The input device 2 of the present embodiment rotates to supply the bobbins 91 to the transport device 4. Alternatively, the input device 2 may supply the bobbins 91 to the transport device 4 by using a slope or a conveyor without rotating.

[0029] The control device 3 includes a calculation device such as a CPU, a RAM, and a storage. The storage is an HDD, SSD, 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 3 performs various controls related to the supply device 1 (for example, control to change the attitude of the input device 2).

[0030] The transport device 4 transports the bobbin 91 inserted by the insertion device 2 toward the yarn winding machine. The transport device 4 transports the bobbin 91 using, for example, a slope, a conveyor, a pressing member, or the like.

[0031] Next, the guide portion 17 will be described in detail.

[0032] In the following description, the direction in which the bobbin 91 is transported by the transport surface 16 is simply referred to as the transport direction. Although the bobbin 91 may actually be transported in a meandering manner, the direction along the transport path without considering the meandering corresponds to the transport direction. In addition, the direction perpendicular to the transport direction on the transport surface 16 is referred to as the width direction. FIG. 4 is a view seen in a direction perpendicular to the transport direction. Therefore, FIG. 4 shows the positional relationship of each part of the guide portion 17 when projected onto the transport surface 16. In the following description of the positional relationship of each part of the guide portion 17, the positional relationship when projected onto the transport surface 16 is shown, unless otherwise specified.

[0033] The guide portion 17 is provided to rise vertically or obliquely from the conveying surface 16, and guides the bobbin 91. To guide means to contact the bobbin 91 and adjust the position of the bobbin 91 so that the bobbin 91 does not fall off the conveying surface 16 in the width direction or so that the bobbin 91 flows downstream. In addition, in each guide, a surface that contacts the bobbin 91 and guides the bobbin 91 is referred to as a guide surface. As shown in FIG. 4, the guide portion 17 includes a first parallel guide 21, a second parallel guide 22, a first inclined guide 23, a second inclined guide 24, a first downstream guide 25, and a second downstream guide 26.

[0034] The first parallel guide 21 is provided on the first side (more specifically, the end on the first side in the width direction) from the center in the width direction. The second parallel guide 22 is provided on the second side (more specifically, the end on the second side in the width direction) from the center in the width direction. The first parallel guide 21 and the second parallel guide 22 are provided at positions where they partially overlap in the conveying direction.

[0035] The guide surface of the first parallel guide 21 and the guide surface of the second parallel guide 22 are parallel. Therefore, the length in the width direction of the conveying surface 16 is the same in the range where the first parallel guide 21 and the second parallel guide 22 are provided. The first parallel guide 21 and the second parallel guide 22 are plate members attached to the conveying surface 16. However, the first parallel guide 21 and the second parallel guide 22 may be block-shaped or other shaped members.

[0036] The first inclined guide 23 and the second inclined guide 24 are provided downstream of the first parallel guide 21 and the second parallel guide 22 in the conveying direction. The first inclined guide 23 is provided on the first side (specifically, near the end of the first side in the width direction) from the center in the width direction. The second inclined guide 24 is provided on the second side (specifically, near the end of the second side in the width direction) from the center in the width direction. The second inclined guide 24 is provided downstream of the range in which the first inclined guide 23 is provided in the conveying direction. Therefore, the first inclined guide 23 and the second inclined guide 24 are provided at completely different positions in the conveying direction (i.e., there is no overlap). Note that the first inclined guide 23 and the second inclined guide 24 may be provided at positions where they overlap only partially in the conveying direction. In other words, the range in which the first inclined guide 23 and the second inclined guide 24 are provided does not completely match. Therefore, the guide surface of the first inclined guide 23 and the guide surface of the second inclined guide 24 are asymmetric with respect to a virtual line passing through the center in the width direction.

[0037] The first inclined guide 23 and the second inclined guide 24 include portions that are inclined so as to move the bobbin 91 inward in the width direction. In other words, the guide surface of the first inclined guide 23 includes a portion that approaches the second side as it approaches the downstream. The guide surface of the second inclined guide 24 includes a portion that approaches the first side as it approaches the downstream. The first inclined guide 23 includes a block-shaped (box-shaped) first member 31 and second member 32. The second inclined guide 24 is a plate member attached to the conveying surface 16.

[0038] The configuration of the first inclined guide 23 will be described in more detail. As shown in Fig. 5, the first member 31 has a first inclined surface 31a which is a guide surface, and an attachment portion 31b. The attachment portion 31b is attached to the first parallel guide 21 using a fastener such as a bolt. The second member 32 has a second inclined surface 32a which is a guide surface, and a parallel surface 32b. The parallel surface 32b is a surface parallel to the conveying direction. An accommodation space is formed inside the second member 32, and a part of the first member 31 can be accommodated therein.

[0039] The first parallel guide 21 has a mounting surface 21a at the downstream end in the conveying direction. The mounting surface 21a is attached to the support plate 18. The support plate 18 has a plurality of mounting holes, and the mounting position can be changed by changing the mounting holes used for mounting to the mounting surface 21a. On the other hand, the second member 32 is fixed to the support plate 18 or the conveying surface 16, etc., and the second member 32 does not move even if the first member 31 is moved. This makes it possible to change the position of the first member 31 relative to the second member 32. As a result, as shown in FIG. 6, the length of the first inclined surface 31a that functions as a guide surface and the length in the width direction of the conveying surface 16 can be changed. For example, by changing the position of the first member 31 relative to the second member 32 depending on the shape, length, amount, etc. of the bobbins 91 to be conveyed, an appropriate guide shape can be realized.

[0040] The shapes of the first member 31 and the second member 32 are merely examples and are not limited to the examples shown in this embodiment. For example, an accommodation space may be formed in the first member 31, and the second member 32 may be accommodated in the accommodation space of the first member 31. Also, an accommodation space may not be formed in either the first member 31 or the second member 32. Also, the first inclined guide 23 may be a single component without being divided into the first member 31 and the second member 32.

[0041] The first downstream guide 25 and the second downstream guide 26 are provided downstream of the first inclined guide 23 and the second inclined guide 24 in the transport direction. The first downstream guide 25 is provided on the first side (more specifically, the end on the first side in the width direction) from the center in the width direction. The second downstream guide 26 is provided on the second side (more specifically, the end on the second side in the width direction) from the center in the width direction. The first downstream guide 25 and the second downstream guide 26 are provided at positions that overlap in the transport direction.

[0042] The guide surface of the first downstream guide 25 and the guide surface of the second downstream guide 26 are parallel to each other. Therefore, the length in the width direction of the conveying surface 16 is the same in the range where the first downstream guide 25 and the second downstream guide 26 are provided. The first downstream guide 25 and the second downstream guide 26 are plate members attached to the conveying surface 16. However, the first downstream guide 25 and the second downstream guide 26 may be block-shaped or other shaped members.

[0043] Next, with reference to Figs. 7 and 8, the guide portion 17 of the comparative example and the guide portion 17 of the present embodiment will be compared with respect to how easily the bobbin 91 becomes clogged.

[0044] The guide portion 17 of the comparative example shown in Fig. 7 has a shape symmetrical with respect to a virtual line passing through the center in the width direction. In the comparative example, when the bobbin 91 passes through the first inclined guide 23 and the second inclined guide 24, the bobbins 91 on both sides in the width direction move toward the center in the width direction. As a result, the forces of the bobbins on both sides moving toward the inside in the width direction are balanced, and the bobbin 91 is likely to become clogged at the clog occurrence location shown in Fig. 7 and its surroundings.

[0045] In contrast, in the guide section 17 of the present embodiment, the first inclined guide 23 and the second inclined guide 24 do not overlap in the conveying direction, so in the present embodiment, the first inclined guide 23 moves the bobbin 91 on the first side to the center in the width direction, and then the second inclined guide 24 moves the bobbin 91 on the second side to the center in the width direction. Therefore, in the present embodiment, the bobbins 91 on both sides in the width direction do not move toward the center in the width direction at the same point in the conveying direction. Therefore, clogging of the bobbins 91 is unlikely to occur. As a result, the frequency of stopping the insertion device 2 is reduced, and the frequency of the operator clearing clogging of the bobbins 91 is reduced.

[0046] Even if the first inclined guide 23 and the second inclined guide 24 are provided at positions where they only partially overlap in the transport direction, the same effect that clogging of the bobbin 91 is unlikely to occur can be achieved.

[0047] Next, preferred sizes and angles of each part of the guide part 17 will be described with reference to Fig. 4. Note that the sizes and angles described below are merely examples and may deviate from the preferred examples.

[0048] In order to maximize the above-mentioned effects, it is preferable to greatly differ the positions of the first inclined guide 23 and the second inclined guide 24 in the conveying direction. The separation distance L1, which is an index for this purpose, will be described. As shown in FIG. 4, the separation distance L1 is the separation distance in the conveying direction between the downstream end of the inclined surface of the first inclined guide 23 in the conveying direction and the downstream end of the inclined surface of the second inclined guide 24 in the conveying direction. The longer the separation distance, the less likely the bobbin 91 will become clogged, but on the other hand, the size of the device will become larger. Considering these points and the size of the bobbin 91, it is preferable that the separation distance L1 is 50 mm or more and 240 mm or less.

[0049] Next, the length L2 of the second inclined surface 32a will be described. It is preferable that the length L2 is long in order to move the bobbin 91 inward in the width direction, particularly to gradually change the orientation of the bobbin 91. However, if the length L2 is too long, the size of the device increases. Considering these points and the size of the bobbin 91, it is preferable that the length L2 is 80 mm or more and 200 mm or less.

[0050] Next, the inclination angles of the first member 31 and the second member 32 will be described. The inclination angles of the first inclined guide 23 and the second inclined guide 24 are angles (acute angles) of inclination with respect to the conveying direction when the first inclined guide 23 and the second inclined guide 24 are projected onto the conveying surface 16. The inclination angle of the first inclined surface 31a of the first member 31 is angle θ1α, the inclination angle of the second inclined surface 32a of the second member 32 is angle θ1β, and the inclination angle of the inclined surface (guide surface) of the second inclined guide 24 is angle θ2. The angle θ1α is smaller than the angle θ1β. This makes it difficult for the first member 31 to interfere with the second member 32 when the first member 31 is moved relative to the second member 32. In addition, the angle θ1β is larger than the angle θ2. The large angle θ1β reduces the length of the first inclined guide 23 in the conveying direction. Therefore, when the length of the guide portion 17 in the conveying direction is fixed, the separation distance L1 becomes longer. As a result, as described above, the effect that clogging of the bobbin 91 hardly occurs can be achieved.

[0051] Furthermore, when the angles θ1α and θ1β are different, a gap is generated in the range where the first inclined surface 31a and the second inclined surface 32a overlap by moving the first member 31 relative to the second member 32 (see FIG. 6). In this embodiment, since the angle θ1α is smaller than the angle θ1β, this gap can be positioned inside the second member 32. Therefore, the bobbin 91 does not enter the gap. Furthermore, even when the second member 32 enters the accommodation space of the first member 31, since the angle θ1α is smaller than the angle θ1β, the gap can be positioned inside the first member 31. From this viewpoint as well, it is preferable that the angle θ1α is smaller than the angle θ1β.

[0052] The magnitude relationship between the angles θ1α and θ1β is an example, and the angles θ1α and θ1β may be the same. In this case, the second member 32 may be accommodated in the accommodation space of the first member 31, or the first member 31 may be accommodated in the accommodation space of the second member 32. From the viewpoint of making it difficult for the transported bobbin 91 to get caught, it is preferable that the second member 32 is accommodated in the accommodation space of the first member 31. The angle θ1α may be larger than the angle θ1β.

[0053] Next, replacement of the first inclined guide 23 will be described with reference to FIG.

[0054] As described above, the first member 31 can be moved relative to the second member 32 according to the length of the bobbin 91, etc., to achieve an appropriate size for the guide portion 17. However, since the position of the second member 32 is fixed, there is a limit to the amount of movement of the first member 31. Therefore, by configuring the first inclined guide 23 to be replaceable, it becomes possible to respond to a wider variety of conditions.

[0055] Each of the first inclined guides 23 has a different size of the first member 31 and the second member 32. For example, the length of the first member 31 in the conveying direction, the length of the second member 32 in the conveying direction, the angle θ1α, the angle θ1β, etc. are different. In addition, as shown in the bottom diagram of Fig. 9, the first inclined guide 23 may be a single part. All of the first inclined guides 23 have a common mounting structure to the rotating unit 11.

[0056] As described above, the supply device 1 of this embodiment includes the conveying device 4 and the input device 2. The conveying device 4 conveys the bobbin 91 wound with a thread. The input device 2 inputs the bobbin 91 from the container 90 in which the bobbin 91 is stored into the conveying device 4. The input device 2 has a conveying surface 16 and a guide section 17. On the conveying surface 16, the bobbin 91 input from the container 90 to the conveying device 4 flows and is conveyed. The guide section 17 is provided to rise from the conveying surface 16 and guides the bobbin 91. The conveying surface 16 has a shape that becomes lower as it approaches the downstream of the conveying direction in which the bobbin 91 is conveyed. The guide section 17 has a first inclined guide 23 and a second inclined guide 24. The first inclined guide 23 is located on a first side of the center of the width of the conveying surface 16 in the width direction perpendicular to the conveying direction, and has inclined surfaces (first inclined surface 31a and second inclined surface 32a) that move the bobbin 91 inward in the width direction. The second inclined guide 24 is located on a second side of the center of the width of the conveying surface 16 in the width direction, and has an inclined surface that moves the bobbin 91 inward in the width direction. The inclined surfaces of the first inclined guide 23 and the second inclined guide 24 are provided at positions that only partially overlap in the conveying direction or at completely different positions.

[0057] As a result, the ranges where the first inclined guide 23 and the second inclined guide 24 are provided do not coincide with each other in the transport direction. Therefore, the forces of the bobbins 91 acting inward in the width direction are unlikely to be balanced, and the bobbins transported on the transport surface are unlikely to become clogged.

[0058] In the supply device 1 of this embodiment, the distance L1 in the transport direction between the downstream end of the inclined surface of the first inclined guide 23 and the downstream end of the inclined surface of the second inclined guide 24 is 50 mm or more and 240 mm or less.

[0059] This makes it possible to maintain the minimum length required to prevent clogging of the bobbin 91, while preventing the device size from becoming excessively large.

[0060] In the supply device 1 of this embodiment, the first inclined guide 23 has a first member 31 and a second member 32. The second member 32 is disposed downstream of the first member 31 in the conveying direction. When the first member 31 and the second member 32 are projected onto the conveying surface 16, the angle θ1α at which the first inclined surface 31a of the first member 31 is inclined with respect to the conveying direction is different from the angle θ1β at which the second inclined surface 32a of the second member 32 is inclined with respect to the conveying direction.

[0061] In this way, by using two members with inclined surfaces having different angles, it becomes easier to achieve both the effect of preventing clogging of the bobbin 91 from occurring and the effect of preventing the device size from becoming excessively large.

[0062] In the supply device 1 of this embodiment, when the second member 32 and the second inclined guide 24 are projected onto the conveying surface 16, the angle θ2 at which the second inclined surface 32a of the second member 32 is inclined with respect to the conveying direction is greater than the angle θ1β at which the inclined surface of the second inclined guide 24 is inclined with respect to the conveying direction.

[0063] The large angle of the second inclined surface 32a of the second member 32 reduces the length of the first inclined guide 23 in the conveying direction. Therefore, the length of the range in the conveying direction where the first inclined guide 23 is not provided and where the second inclined guide 24 is provided can be increased. This makes it even more difficult for the bobbin 91 to become clogged.

[0064] In the supply device 1 of this embodiment, when the first member 31 and the second member 32 are projected onto the conveying surface 16, the angle θ1α at which the first inclined surface 31a of the first member 31 is inclined with respect to the conveying direction is smaller than the angle θ1β at which the second inclined surface 32a of the second member 32 is inclined with respect to the conveying direction. The second member 32 has a space capable of accommodating a part of the first member 31. The first member 31 is movable relative to the second member 32 so as to enter the space of the second member 32.

[0065] Thereby, by moving the first member 31 relative to the second member 32, the shape or size of the first inclined guide 23 can be changed.

[0066] In the supply device 1 of this embodiment, when the second member 32 is projected onto the transport surface 16, the length L2 of the second inclined surface 32a of the second member 32 is not less than 80 mm and not more than 200 mm.

[0067] This makes it possible to appropriately guide the bobbin 91 inward in the width direction, while preventing the device size from becoming excessively large.

[0068] In the supply device 1 of this embodiment, the input device 2 includes a rotating part 11 that rotates integrally with the conveying surface 16 around the horizontal direction as the center of rotation. The rotation of the rotating part 11 changes the position of the input device 2 between a preparation position and an input position. The preparation position is a position for setting the container 90.
