AI Technical Summary
During the transportation process of yarn pipes, as the downstream of the conveying direction approaches the narrower position, the yarn pipes are prone to clogging, because the force balance of the yarn pipes on both sides leads to a trend in the inner side of the width direction, making it difficult to effectively solve the existing guide plate structure This question.

Abstract
Description
Technical Field
[0001] The present invention mainly relates to a supply device for feeding bobbins into a conveying device. Background Art
[0002] Patent Document 1 is Japanese Patent Application Publication No. 2013-6669.
[0003] Patent document 1 discloses a yarn feeding tube supplying device for supplying a yarn feeding tube contained in a cart to an automatic winding machine. The yarn feeding tube supplying device includes a feeding device. The feeding device discharges the yarn feeding tube contained in the cart by rotating the cart. Guide plates are provided at both ends of the feeding device in the width direction. The guide plates guide the yarn feeding tube discharged from the cart so that it does not fall to the outside in the width direction.
[0004] In the structure of guiding the bobbin by the guide plate as in Patent Document 1, if there is a portion where the width becomes narrower as it approaches the downstream in the bobbin feeding direction, the bobbins on both sides may have a balanced force moving inward in the width direction, causing the bobbins to become clogged. Summary of the invention
[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 in which the bobbin is less likely to be clogged at a portion where the width of the bobbin conveying surface is narrowed.
[0006] The problems to be solved by the present invention are as described above. Next, means for solving the problems and their effects will be described.
[0007] According to an aspect of the present invention, a supply device having the following structure is provided. That is, the supply device includes a conveying device and an inserting device. The conveying device conveys a bobbin wound with a yarn. The inserting device inserts the bobbin from a container that contains the bobbin into the conveying device. The inserting device includes a conveying surface and a guide portion. The bobbin inserted from the container into the conveying device flows on the conveying surface and is conveyed. The guide portion is provided in a manner of standing up from the conveying surface to guide the bobbin. The conveying surface has a shape that becomes lower as it approaches downstream in a conveying direction in which the bobbin is conveyed. The guide portion includes a first inclined guide and a second inclined guide. The first inclined guide is located on the conveying surface and on a first side relative to a center of the conveying surface in a width direction orthogonal to the conveying direction, and has an inclined surface that gathers the bobbin toward the inside in the width direction. The second inclined guide is located on a second side relative to a center of the conveying surface in the width direction, and has an inclined surface that gathers the bobbin toward the inside in the width direction. The inclined surface of the first inclined guide and the inclined surface of the second inclined guide are provided at positions that only partially overlap or at completely different positions in the conveying direction.
[0008] Thus, the ranges where the first inclined guide and the second inclined guide are provided are not consistent in the conveying direction. Therefore, since the forces of the bobbins moving inward in the width direction are difficult to be balanced, the bobbins conveyed on the conveying surface are less likely to be clogged.
[0009] In the supply device, preferably, a separation distance in the conveying direction between a downstream end of the inclined surface of the first inclined guide and a downstream end of the inclined surface of the second inclined guide is 50 mm to 240 mm.
[0010] Thus, the minimum length for preventing bobbin clogging from occurring can be maintained, and the device size can be suppressed from becoming excessively large.
[0011] In the supply device, it is preferable to have the following structure. That is, the first inclined guide has a first component and a second component. The second component is arranged downstream of the first component in the conveying direction. When the first component and the second component are projected on the conveying surface, the angle at which the inclined surface of the first component is inclined relative to the conveying direction is different from the angle at which the inclined surface of the second component is inclined relative to the conveying direction.
[0012] Thus, by using two members having inclined surfaces at different angles, it is easy to simultaneously achieve the effect of preventing bobbin clogging from occurring and the effect of suppressing the device from becoming oversized.
[0013] In the supply device, preferably, when the second component and the second inclined guide are projected on the conveying surface, the inclined surface of the second component is inclined at an angle greater than the inclined surface of the second inclined guide relative to the conveying direction.
[0014] Since the angle of the inclined surface of the second component is large, the length of the first inclined guide in the conveying direction can be reduced. Therefore, the length of the range where the first inclined guide is not provided and the second inclined guide is provided can be extended in the conveying direction. As a result, bobbin clogging is less likely to occur.
[0015] In the supply device, it is preferable to adopt the following structure. That is, when the first component and the second component are projected on the conveying surface, the angle at which the inclined surface of the first component is inclined relative to the conveying direction is smaller than the angle at which the inclined surface of the second component is inclined relative to the conveying direction. The second component has a space capable of accommodating a part of the first component. The first component can move relative to the second component in a manner of entering the space of the second component.
[0016] Thus, by moving the first member relative to the second member, the shape or size of the first inclined guide can be changed.
[0017] In the supply device, preferably, when the second member is projected onto the conveying surface, a length of the inclined surface of the second member is not less than 80 mm and not more than 200 mm.
[0018] Thus, the bobbin can be appropriately guided inward in the width direction, and the size of the device can be suppressed from becoming excessively large.
[0019] In the supply device, the following structure is preferably used. That is, the input device has a rotating part that rotates integrally with the conveying surface with the horizontal direction as the rotation center. The posture of the input device changes between a preparation posture and an input posture by the rotation of the rotating part. The preparation posture is a posture for assembling the container. The input posture is a posture in which the height of the conveying surface becomes lower as it approaches the downstream of the conveying direction.
[0020] Thus, when the insertion device is changed from the preparation position to the insertion position, it is possible to prevent the bobbin from being blocked.
[0021] In the supply device, the following structure is preferably adopted. That is, the rotating part is formed with an outer peripheral surface, and the outer peripheral surface restricts the movement of the bobbin when the insertion device changes from the preparation posture to the insertion posture so that the bobbin located at the upstream end of the conveying device does not move further to the upstream side. When the outer peripheral surface is observed in the direction of the rotation axis of the rotating part, the outer peripheral surface includes an arc-shaped surface.
[0022] Thus, since the outer peripheral surface includes an arc-shaped surface, the yarn or the bobbin is not easy to be hooked between the outer peripheral surface and other components. In addition, the bobbin is not easy to be clamped between the outer peripheral surface and other components. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Next, embodiments of the present invention will be described with reference to the drawings.
[0033] First, refer to Figures 1 to 3 The supply device 1 is briefly described. The supply device 1 is a device that supplies a bobbin 91 having a yarn wound around a core tube. The bobbin supplied by the supply device 1 is supplied to a yarn winding machine such as an automatic winder. The yarn winding machine winds the yarn wound around the bobbin to form a package. Figure 1 As shown, the supply device 1 includes a charging device 2 , a control device 3 , and a conveying device 4 .
[0034] Assemble on the input device 2 Figure 2 The housing body 90 shown in the figure has a bottom and a plurality of side surfaces arranged upright from the bottom, and a housing space is formed inside the bottom. A bobbin 91 is accommodated in the housing space of the housing body 90.
[0035] The input device 2 includes a rotating part 11, a rotating shaft 12, and a motor 13. The rotating part 11 is supported on the rotating shaft 12 in a rotatable manner. The axial direction of the rotating shaft 12 is parallel to the horizontal direction. The motor 13 is an electric motor that generates power based on the command of the control device 3. The rotating part 11 rotates by the power generated by the motor 13.
[0036] The first frame 14, the second frame 15, the conveying surface 16, and the guide 17 are fixed to the rotating part 11. The first frame 14, the second frame 15, the conveying surface 16, and the guide 17 rotate integrally with the rotating part 11. The container 90 is assembled on the first frame 14 and the second frame 15. The conveying surface 16 is a surface for conveying the bobbin 91 supplied from the container 90 to flow toward the conveying device 4. The guide 17 guides the bobbin 91 flowing on the conveying surface 16.
[0037] The posture of the feeding device 2 is changed between the preparation posture and the feeding posture by the rotation of the rotating part 11. The preparation posture is a posture for assembling the container 90 to the first frame 14 and the second frame 15. The feeding posture is a posture for feeding the bobbin 91. In the feeding posture, since the height of the conveying surface 16 becomes lower as it approaches the downstream in the conveying direction, the bobbin 91 flows along the conveying surface 16 by its own weight.
[0038] The rotating part 11 further includes an outer peripheral surface 19. When the rotating part 11 is viewed in the axial direction of the rotating shaft 12, the outer peripheral surface 19 is a surface including an arc-shaped portion. The outer peripheral surface 19 is formed downstream in the conveying direction of the conveying surface 16 (downstream in the rotation direction when changing from the preparation position to the insertion position). When the insertion device 2 is changed from the preparation position to the insertion position, the outer peripheral surface 19 restricts the movement of the bobbin 91 so that the bobbin 91 located at the upstream end of the conveying device 4 does not further reach the upstream side area (specifically, the space for rotating the rotating part 11).
[0039] The outer peripheral surface 19 is formed by bending the plate. The bending process is, for example, roller bending in which a plurality of rollers are used to bend the plate. In addition, the arc plate constituting the outer peripheral surface 19 may be one or more. In the case where there are more than one arc plate constituting the outer peripheral surface 19, the arc plates are joined to each other. In addition, a gap is sometimes formed at the joint portion between the arc plates. At least a portion of the gap between the arc plates may also be covered by a cover member. Thus, the yarn or the bobbin 91 is not easily hooked in the gap between the arc plates. Moreover, the bobbin 91 is less likely to be sandwiched between the outer peripheral surface 19 and other components. In addition, the cover member is arranged from one side of the adjacent arc plates toward the other side. At this time, it is more preferable to arrange the cover member from the arc plate on the downstream side of the rotation direction of the rotating part 11 when changing from the preparation posture to the input posture toward the arc plate on the upstream side. Thus, the yarn or the bobbin 91 is not easily sandwiched between the cover member and the upstream end of the conveying device 4. It should be noted that the cover member is not an essential component and can be omitted. In addition, the position, range, and direction of the cover member may be changed as appropriate. A part of the arc plate may be used as the cover member.
[0040] The outer peripheral surface 19 need not be entirely arc-shaped, but may be partially arc-shaped. In particular, when the loading device 2 is changed from the preparation position to the loading position, at least the portion closest to the conveying device 4 may be arc-shaped.
[0041] Since the outer peripheral surface 19 includes an arc-shaped surface, the yarn or the bobbin 91 is not easily caught on the outer peripheral surface 19. Therefore, the bobbin 91 in contact with the outer peripheral surface 19 can be smoothly guided downstream. It should be noted that the outer peripheral surface 19 is an example of an arc shape, and the outer peripheral surface 19 may be a polygon when viewed in the axial direction of the rotating shaft 12. The polygonal outer peripheral surface 19 can be formed by forming a plurality of V-shaped bends on a plate.
[0042] The feeding device 2 of this embodiment rotates to supply the bobbin 91 to the conveying device 4. Alternatively, the feeding device 2 may supply the bobbin 91 to the conveying device 4 via an inclined surface or a conveyor without rotating.
[0043] The control device 3 has a CPU and other computing devices, RAM and storage. The storage is a HDD, SSD or flash memory. The storage stores programs related to the supply device 1 and data such as conditions required to execute the programs. The computing device reads the programs stored in the storage into the RAM and executes them. Thus, the control device 3 performs various controls related to the supply device 1 (for example, control of changing the posture of the input device 2).
[0044] The transport device 4 transports the bobbin 91 inserted by the inserting device 2 toward the yarn winding machine. The transport device 4 transports the bobbin 91 using, for example, an inclined surface, a conveyor, or a pressing member.
[0045] Next, the guide portion 17 will be described in detail.
[0046] 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. In fact, the bobbin 91 may be transported while meandering, but the direction along the transport path without considering the meandering corresponds to the transport direction. In addition, on the transport surface 16, the direction orthogonal to the transport direction is referred to as the width direction. Figure 4 is a graph observed in a direction perpendicular to the conveying direction. Therefore, Figure 4 The positional relationship of each part of the guide 17 when projected onto the conveying surface 16 is shown. Hereinafter, when describing the positional relationship of each part of the guide 17, the positional relationship when projected onto the conveying surface 16 is shown unless otherwise specified.
[0047] The guide portion 17 is provided vertically or obliquely from the conveying surface 16 to guide the bobbin 91. The so-called guidance means to contact the bobbin 91 to adjust the position of the bobbin 91 so that the bobbin 91 does not fall from the conveying surface 16 in the width direction or to make the bobbin 91 flow downstream. In addition, in each guide, the surface that contacts the bobbin 91 to guide the bobbin 91 is called a guide surface. Figure 4As shown, 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 .
[0048] The first parallel guide 21 is provided on the first side (specifically, the end of the first side in the width direction) compared to the center in the width direction. The second parallel guide 22 is provided on the second side (specifically, the end of the second side in the width direction) compared to the center in the width direction. The first parallel guide 21 and the second parallel guide 22 are provided at a position where they partially overlap in the conveying direction. The first side and the second side in the width direction are in a relative positional relationship with respect to the center in the width direction of the conveying surface 16.
[0049] The guide surface of the first parallel guide 21 is parallel to the guide surface of the second parallel guide 22. Therefore, the lengths in the width direction of the conveying surface 16 are the same within 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 mounted on the conveying surface 16. However, the first parallel guide 21 and the second parallel guide 22 may be block-shaped or other shaped members.
[0050] 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) compared to the center in the width direction. The second inclined guide 24 is provided on the second side (specifically, the end of the second side in the width direction) compared to the center in the width direction. In the conveying direction, the second inclined guide 24 is provided downstream of the range in which the first inclined guide 23 is provided. Therefore, the first inclined guide 23 and the second inclined guide 24 are provided at completely different positions in the conveying direction (that is, they do not overlap at all). It should be noted that the first inclined guide 23 and the second inclined guide 24 may also be provided at positions in which only a portion of them overlap in the conveying direction. That is, the ranges in which the first inclined guide 23 and the second inclined guide 24 are provided are not completely consistent. Therefore, the guide surface of the first inclined guide 23 and the guide surface of the second inclined guide 24 are not symmetrical with respect to an imaginary line passing through the center in the width direction.
[0051] The first inclined guide 23 and the second inclined guide 24 include portions inclined so as to gather the bobbins 91 toward the inner side 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 downstream. The guide surface of the second inclined guide 24 includes a portion that approaches the first side as it approaches downstream. The first inclined guide 23 includes a first block-shaped (box-shaped) member 31 and a second member 32. The second inclined guide 24 is a plate member mounted on the conveying surface 16.
[0052] The structure of the first inclined guide 23 will be described in more detail. Figure 5 As shown, the first component 31 includes a first inclined surface 31a as a guide surface and a mounting portion 31b. The mounting portion 31b is mounted on the first parallel guide 21 using a mounting member such as a bolt. The second component 32 includes a second inclined surface 32a as a guide surface and a parallel surface 32b. The parallel surface 32b is a surface parallel to the conveying direction. In addition, a storage space is formed inside the second component 32, which can accommodate a part of the first component 31.
[0053] A mounting surface 21a is provided at the downstream end portion in the conveying direction of the first parallel guide 21. The mounting surface 21a is mounted on the support plate 18. In addition, a plurality of mounting holes are formed on the support plate 18, and the mounting position can be changed by changing the mounting holes used in the mounting with the mounting surface 21a. On the other hand, the second component 32 is fixed to the support plate 18 or the conveying surface 16, etc., and the second component 32 does not move even if the first component 31 is moved. Thus, the position of the first component 31 relative to the second component 32 can be changed. As a result, if Figure 6 As shown, the length of the first inclined surface 31a functioning 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 according to the shape, length, number, etc. of the bobbin 91 to be conveyed, an appropriate guide shape can be achieved.
[0054] The shapes of the first component 31 and the second component 32 are just examples, and are not limited to the examples shown in this embodiment. For example, a storage space may be formed in the first component 31, and the second component 32 may be stored in the storage space of the first component 31. In addition, a storage space may not be formed in either the first component 31 or the second component 32. In addition, the first inclined guide 23 may be formed as one component without being divided into the first component 31 and the second component 32.
[0055] 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 conveying direction. The first downstream guide 25 is provided on the first side (specifically, the end on the first side in the width direction) compared to the center in the width direction. The second downstream guide 26 is provided on the second side (specifically, the end on the second side in the width direction) compared to the center in the width direction. The first downstream guide 25 and the second downstream guide 26 are provided at overlapping positions in the conveying direction.
[0056] The guide surface of the first downstream guide 25 is parallel to the guide surface of the second downstream guide 26. Therefore, the lengths in the width direction of the conveying surface 16 are the same within 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 mounted on the conveying surface 16. However, the first downstream guide 25 and the second downstream guide 26 may be block-shaped or other shaped members.
[0057] Next, refer to Figure 7 and Figure 8 The difficulty of clogging of the bobbin 91 in the guide portion 17 of the comparative example and the guide portion 17 of the present embodiment is compared.
[0058] Figure 7 The guide portion 17 of the comparative example shown is symmetrical with respect to an imaginary 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 bobbin 91 on both sides in the width direction tends to the center in the width direction. As a result, the forces of the bobbins on both sides tending to the inner side in the width direction are balanced. Figure 7 The clogging position shown and its surroundings are prone to clogging of the bobbin 91.
[0059] In contrast, in the guide portion 17 of the present embodiment, the first inclined guide 23 and the second inclined guide 24 do not overlap in the conveying direction. Therefore, in the present embodiment, after the bobbin 91 on the first side is gathered toward the center in the width direction by the first inclined guide 23, the bobbin 91 on the second side is gathered toward the center in the width direction by the second inclined guide 24. Therefore, in the present embodiment, the bobbin 91 on both sides in the width direction does not move toward the center in the width direction at the same position in the conveying direction. Therefore, the bobbin 91 is less likely to be blocked. As a result, the frequency of stopping the feeding device 2 is reduced, and the frequency of the operator clearing the blockage of the bobbin 91 is reduced.
[0060] Even when the first inclined guide 23 and the second inclined guide 24 are provided at positions where they only partially overlap in the feeding direction, the bobbin 91 is less likely to be clogged than the guide portion 17 of the comparative example.
[0061] Next, refer to Figure 4 The following describes the preferred dimensions and angles of the various parts of the guide portion 17. Note that the dimensions and angles described below are examples, and may deviate from the preferred examples.
[0062] In order to maximize the above-mentioned effect, it is preferable that the positions of the first inclined guide 23 and the second inclined guide 24 in the conveying direction are greatly different. The separation distance L1 as an index for this purpose is described below. Figure 4 As shown in FIG. 1 , 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 is, the less likely the bobbin 91 is to be clogged, but on the other hand, the size of the device becomes larger. Considering these points and the size of the bobbin 91, the separation distance L1 is preferably not less than 50 mm and not more than 240 mm.
[0063] Next, the length L2 of the second inclined surface 32a is described. In order to gather the bobbin 91 inward in the width direction, especially to gradually change the direction of the bobbin 91, it is preferable that the length L2 is long. However, if the length L2 is too long, the size of the device will increase. Considering these aspects and the size of the bobbin 91, the length L2 is preferably not less than 80 mm and not more than 200 mm.
[0064] Next, the inclination angles of the first component 31 and the second component 32 are described. The inclination angles of the first inclined guide 23 and the second inclined guide 24 are angles (acute angles) at which the first inclined guide 23 and the second inclined guide 24 are inclined relative 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 component 31 is set to angle θ1α, the inclination angle of the second inclined surface 32a of the second component 32 is set to angle θ1β, and the inclination angle of the inclined surface (guide surface) of the second inclined guide 24 is set to angle θ2. Angle θ1α is smaller than angle θ1β. Thus, when the first component 31 is moved relative to the second component 32, the first component 31 is less likely to interfere with the second component 32. In addition, angle θ1β is larger than angle θ2. Since angle θ1β is large, the length of the first inclined guide 23 in the conveying direction can be suppressed. Therefore, when the length of the guide portion 17 in the conveying direction is determined, the separation distance L1 becomes longer. As a result, as described above, the effect of preventing the bobbin 91 from being clogged can be achieved.
[0065] When the angle θ1α is different from the angle θ1β, 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 Figure 6 ). In the present embodiment, since the angle θ1α is smaller than the angle θ1β, the gap can be located inside the second member 32. Therefore, the bobbin 91 does not enter the gap. In addition, even when the second member 32 enters the storage space of the first member 31, since the angle θ1α is smaller than the angle θ1β, the gap can be located inside the first member 31. From this viewpoint, it is also preferable that the angle θ1α is smaller than the angle θ1β.
[0066] It should be noted that the magnitude relationship between the angle θ1α and the angle θ1β is an example, and the angle θ1α and the angle 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 bobbin 91 being transported to get caught, it is preferable to accommodate the second member 32 in the accommodation space of the first member 31. In addition, the angle θ1α may be larger than the angle θ1β.
[0067] Next, refer to Fig. 9 Replacement of the first inclined guide 23 will be described.
[0068] As described above, by moving the first member 31 relative to the second member 32 according to the length of the bobbin 91, etc., it is possible to achieve an appropriate size of the guide portion 17. However, there is a case where the position of the second member 32 is fixed, and 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 is possible to cope with more various conditions.
[0069] In each first inclined guide 23, the shape of the first component 31 or the second component 32 is different, or the components constituting the first inclined guide 23 are different. For example, the length of the first component 31 in the conveying direction, the length of the second component 32 in the conveying direction, the angle θ1α, the angle θ1β, etc. are different. Fig. 9 As shown in the bottom figure of the figure, the first inclined guide 23 may also be a single component. The mounting structure of any of the first inclined guides 23 to the rotating portion 11 is common.
[0070] As described above, the supply device 1 of this embodiment includes the conveying device 4 and the inserting device 2. The conveying device 4 conveys the bobbin 91 wound with the yarn. The inserting device 2 inserts the bobbin 91 from the container 90 containing the bobbin 91 into the conveying device 4. The inserting device 2 includes the conveying surface 16 and the guide portion 17. The bobbin 91 inserted from the container 90 into the conveying device 4 flows on the conveying surface 16 and is conveyed. The guide portion 17 is provided in a manner of standing 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 in the conveying direction in which the bobbin 91 is conveyed. The guide portion 17 includes the first inclined guide 23 and the second inclined guide 24. The first inclined guide 23 is located on the conveying surface 16 and in the width direction orthogonal to the conveying direction, and is located on the first side of the width direction center of the conveying surface 16, and has an inclined surface (the first inclined surface 31a and the second inclined surface 32a) for collecting the bobbin 91 to the inside in the width direction. The second inclined guide 24 is located on the second side in the width direction relative to the center of the conveying surface 16 in the width direction, and has an inclined surface for gathering the bobbin 91 inward in the width direction. The inclined surface of the first inclined guide 23 and the inclined surface of the second inclined guide 24 are provided at positions that only partially overlap or at completely different positions in the conveying direction.
[0071] Thus, the ranges where the first inclined guide 23 and the second inclined guide 24 are provided are not consistent in the conveying direction. Therefore, the forces of the bobbins 91 moving inward in the width direction are difficult to be balanced, and the bobbins conveyed on the conveying surface are less likely to be clogged.
[0072] In the supply device 1 of the present embodiment, a separation distance L1 in the conveying 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 to 240 mm.
[0073] Thus, the minimum length for preventing the bobbin 91 from being clogged can be maintained, and the device size can be suppressed from becoming excessively large.
[0074] In the supply device 1 of the present embodiment, the first inclined guide 23 includes a first component 31 and a second component 32. The second component 32 is arranged downstream of the first component 31 in the conveying direction. When the first component 31 and the second component 32 are projected on the conveying surface 16, the angle θ1α at which the first inclined surface 31a of the first component 31 is inclined relative to the conveying direction is different from the angle θ1β at which the second inclined surface 32a of the second component 32 is inclined relative to the conveying direction.
[0075] Thus, by using two members having inclined surfaces at different angles, it is easy to simultaneously achieve the effect of making the bobbin 91 less likely to be clogged and the effect of suppressing the device from being oversized.
[0076] In the supply device 1 of this embodiment, when the second component 32 and the second inclined guide 24 are projected on the conveying surface 16, the angle θ1β at which the second inclined surface 32a of the second component 32 is inclined relative to the conveying direction is greater than the angle θ2 at which the inclined surface of the second inclined guide 24 is inclined relative to the conveying direction.
[0077] Since the angle of the second inclined surface 32a of the second member 32 is large, the length of the first inclined guide 23 in the conveying direction can be reduced. Therefore, the length of the range in the conveying direction where the first inclined guide 23 is not provided and the second inclined guide 24 is provided can be extended. As a result, the bobbin 91 is less likely to be clogged.
[0078] In the supply device 1 of the present embodiment, when the first component 31 and the second component 32 are projected on the conveying surface 16, the angle θ1α at which the first inclined surface 31a of the first component 31 is inclined relative to the conveying direction is smaller than the angle θ1β at which the second inclined surface 32a of the second component 32 is inclined relative to the conveying direction. The second component 32 has a space that can accommodate a part of the first component 31. The first component 31 can move relative to the second component 32 in a manner that enters the space of the second component 32.
[0079] Thus, 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.
[0080] In the supply device 1 of the present embodiment, when the second member 32 is projected onto the conveyance surface 16 , the length L2 of the second inclined surface 32 a of the second member 32 is not less than 80 mm and not more than 200 mm.
[0081] Thus, the bobbin 91 can be appropriately guided inward in the width direction, and the size of the device can be suppressed from becoming excessively large.
[0082] In the supply device 1 of the present embodiment, the input device 2 includes a rotating portion 11 that rotates integrally with the conveying surface 16 with the horizontal direction as the rotation center. The posture of the input device 2 changes between the preparation posture and the input posture by the rotation of the rotating portion 11. The preparation posture is a posture for assembling the container 90. The input posture is a posture in which the height of the conveying surface 16 becomes lower as it approaches the downstream in the conveying direction.
[0083] This makes it possible to prevent the bobbin 91 from becoming clogged when the insertion device is changed from the preparation position to the insertion position.
[0084] In the supply device 1 of the present embodiment, the outer peripheral surface 19 is formed on the rotating portion 11, and the outer peripheral surface 19 restricts the movement of the bobbin 91 when the insertion device 2 changes from the preparation position to the insertion position so that the bobbin 91 located at the upstream end of the conveying device 4 does not move further to the upstream side. When the outer peripheral surface 19 is viewed in the direction of the rotating shaft 12 of the rotating portion 11, the outer peripheral surface 19 includes an arc-shaped parallel surface 32b.
[0085] Thus, since the outer peripheral surface 19 includes an arc-shaped surface, the yarn or the bobbin 91 is not easily caught between the outer peripheral surface 19 and other components (for example, the upstream end of the conveying device 4). In addition, the bobbin 91 is not easily sandwiched between the outer peripheral surface 19 and other components.
