[0006] In the bobbin supply device of Patent Document 1, for example, when a problem occurs in the individualization section or the tray loading section, the bobbin cannot be loaded onto the tray. As a result, there is a possibility that the winding unit cannot be supplied to the tray, thereby reducing operating efficiency. It should be noted that this problem is not limited to the bobbin supply device attached to the tray-type automatic winding machine, but is a common problem for other supply devices. Summary of the Invention

[0007] The present invention was made in view of the above circumstances, and its main objective is to provide a supply device that can continue to supply the bobbin even when adverse conditions occur.

[0008] The problem to be solved by the present invention is as described above. The means used to solve the problem and its effects will be described below.

[0009] According to the present invention, a supply device with the following structure is provided. That is, the supply device includes a delivery device, a transport section, a separation section, a transfer section, and a control section. The delivery device delivers a bobbin assembly representing a plurality of bobbins wound with yarn. The transport section transports the bobbin assembly delivered by the delivery device. The separation section separates the bobbin assembly transported by the transport section into individual bobbins. The transfer section transfers the individualized bobbins downstream. The control section controls the transport section, the separation section, and the transfer section. The transport section includes an upstream transport section, a first downstream transport section, and a second downstream transport section. The upstream transport section is a path that receives and transports the bobbin assembly delivered by the delivery device. The first downstream transport section transports the bobbin assembly via a path branching from the upstream transport section. The second downstream transport section transports the bobbin assembly via a path different from the first downstream transport section, which is a branch of the upstream transport section. The separation section includes a first separation section and a second separation section. The first individualization section individualizes the tube assembly transported by the first downstream transport section. The second individualization section individualizes the tube assembly transported by the second downstream transport section. The transfer section has a first transfer section and a second transfer section. The first transfer section transfers the tubes individualized by the first individualization section downstream. The second transfer section transfers the tubes individualized by the second individualization section downstream.

[0010] Therefore, since there are two of each of the conveying section, the sorting section, and the handover section, the supply of tubing can continue using the other section even if any one of them malfunctions.

[0011] In the aforementioned supply device, the following structure is preferred: The first downstream transport section has a first limiting section that switches between a state where the transport of the bobbin assembly is restricted and a state where the restriction is lifted. The second downstream transport section has a second limiting section that switches between a state where the transport of the bobbin assembly is restricted and a state where the restriction is lifted.

[0012] Therefore, the necessary amount of tubing can be supplied to the first downstream transport section and the second downstream transport section as needed.

[0013] In the aforementioned supply device, the following structure is preferred: The upstream transport section comprises a front upstream transport section, an upstream restriction section, and a rear upstream transport section. The front upstream transport section receives and transports the tube assembly delivered by the delivery device. The upstream restriction section is connected downstream of the front upstream transport section and switches between a restricted state and a released state for the transport of the tube assembly. The rear upstream transport section is connected downstream of the upstream restriction section and is located upstream of the first downstream transport section and the second downstream transport section.

[0014] Therefore, the amount of tubing supplied downstream can be adjusted upstream of the branch section.

[0015] The supply device preferably has the following structure: The supply device includes a first downstream sensor, a second downstream sensor, and an upstream sensor. The first downstream sensor detects the tube downstream of the first restrictor in the first downstream transport section or the tube in the first individualization section. The second downstream sensor detects the tube downstream of the second restrictor in the second downstream transport section or the tube in the second individualization section. The upstream sensor detects the tube in the upstream transport section. The control unit controls at least one restrictor, including the upstream restrictor, the first restrictor, and the second restrictor, based on the detection results of the first downstream sensor, the second downstream sensor, and the upstream sensor.

[0016] Therefore, at least one of the various limiting parts can be controlled based on the conditions of both the upstream and downstream sides of the first limiting part and the second limiting part.

[0017] In the aforementioned supply device, the following structure is preferred: On a horizontal plane, the direction orthogonal to the transport direction of the transport section is defined as the width direction. At least one limiting part, including the first limiting part and the second limiting part, switches between a restricted state and a released state of transport of the bobbin assembly by moving in the vertical direction. Furthermore, the profile of the upstream end of the limiting part in the transport direction includes a portion that, when viewed from above, slopes upwards as it approaches the center from one side of the width direction, and a portion that, when viewed from above, slopes upwards as it approaches the center from the other side of the width direction, also slopes upwards.

[0018] This allows multiple tubes to be transported separately to one side and the other side in the width direction.

[0019] In the aforementioned supply device, the following structure is preferred: On a horizontal plane, the direction orthogonal to the transport direction of the transport section is defined as the width direction. The upper end of the limiting section includes a portion that, when viewed in the transport direction, slopes upwards as it approaches the center from one side of the width direction, and a portion that, when viewed in the transport direction, slopes upwards as it approaches the center from the other side of the width direction.

[0020] This allows multiple tubes to be transported separately to one side and the other side in the width direction.

[0021] In the aforementioned supply device, the following structure is preferred: The supply device has a first driving unit and a second driving unit. The first driving unit drives the first limiting unit. The second driving unit is separate from the first driving unit and drives the second limiting unit.

[0022] Therefore, the first and second limiting parts can be switched through simple control.

[0023] In the aforementioned supply device, the following structure is preferred: The control unit controls the first limiting unit based on information relating to the number of tubes existing between the first individualizing unit and the first connecting unit. The control unit controls the second limiting unit based on information relating to the number of tubes existing between the second individualizing unit and the second connecting unit.

[0024] Therefore, the supply to each cylinder can be switched based on the conditions of the first and second sides.

[0025] In the aforementioned supply device, preferably, on a horizontal plane, when the direction orthogonal to the transport direction of the transport section is set as the width direction, the upstream transport section has a guide section that restricts the position of the bobbin assembly in the width direction and expands in the width direction as it approaches the downstream.

[0026] This allows for the storage of a larger number of tubes, or ensures a width sufficient to connect with the first downstream transport section and the second downstream transport section.

[0027] In the aforementioned supply device, the following structure is preferred: the first downstream conveying section and the second downstream conveying section are arranged adjacent to each other. The first separation section and the second separation section each have a support platform, a drive section, and a separation member. The support platform supports the bobbin. The drive section generates power to move the support platform in the vertical direction. The separation member is arranged along the range of the support platform moving from the lower to the upper direction, separating the bobbin so that the bobbin supported on the support platform becomes a single unit.

[0028] Therefore, since the two downstream conveying sections are adjacent, the width dimension of the supply device can be suppressed. Furthermore, since it is a structure where two separate conveying sections move vertically, the width dimension of the supply device can also be suppressed at this point.

[0029] In the aforementioned supply device, the following structure is preferred: The control unit controls the conveying speed of the first individualization unit on the bobbins based on information related to the number of bobbins existing between the first individualization unit and the first transfer unit. Similarly, the control unit controls the conveying speed of the second individualization unit on the bobbins based on information related to the number of bobbins existing between the second individualization unit and the second transfer unit.

[0030] Therefore, the conveying speed of the individualized sections' tubes can be adjusted based on the conditions of the first and second sides. As a result, for example, when there is sufficient stock of tubes, it is possible to slow down the conveying speed and stabilize the operation of the individualized sections.

[0031] The preparation device includes the supply device and the delivery device. The delivery device receives the bobbin supplied by the supply device and feeds the received bobbin to a take-up unit to form a package by winding the yarn around the bobbin. The path length from the first individualization section to the first junction section is longer than the path length from the second individualization section to the second junction section. The delivery device has a first receiving path and a second receiving path. The first receiving path receives the bobbin from the first junction section. The second receiving path receives the bobbin from the second junction section at a second junction position. The delivery device has a branch point where the upstream path branches into the first receiving path and the second receiving path. The first path length from the branch point to the first junction position is shorter than the second path length from the branch point to the second junction position.

[0032] Therefore, the path length of the supply device can be increased on the first side of the priority transfer tube. As a result, the storage on the supply device side can be increased in the priority path.

[0033] The preparation device includes the supply device and the delivery device. The delivery device receives the bobbin supplied by the supply device and delivers the received bobbin to a take-up unit that winds the yarn around the bobbin to form a package. The delivery device has a first receiving path and a second receiving path. The first receiving path receives the bobbin from a first junction. The second receiving path receives the bobbin from a second junction at a second junction position. The delivery device has a branch point where the upstream path branches into the first receiving path and the second receiving path. The length of the first path from the branch point to the first junction position is shorter than the length of the second path from the branch point to the second junction position. The operating speed of the first limiting part is faster than the operating speed of the second limiting part.

[0034] Therefore, on the second side where the bobbin is not preferentially handed over, the operating speed of the second limiting section can be made relatively slow. As a result, when the second limiting section is stopped, it is not easy to convey excess bobbin downstream. Attached Figure Description

[0049] Next, embodiments of the present invention will be described with reference to the accompanying drawings. First, referring to... Figure 1 A brief description of the preparation device 100 and the automatic winding machine 110 is provided.

[0050] The preparation device 100 processes the bobbin 5. The bobbin 5 is a structure in which yarn is wound on a core tube, and is sometimes called a yarn supply bobbin. The preparation device 100 prepares the bobbin so that the automatic winding machine 110 can wind up the yarn wound on the bobbin 5. The preparation device 100 includes a supply device 1, a delivery device 2, and an output device 3.

[0051] The supply device 1 supplies bobbins 5 and hands them over to the delivery device 2. The delivery device 2 delivers the received bobbins 5 to the automatic winding machine 110. Specifically, the delivery device 2 is provided with a tray 6 for transporting the bobbins 5. The supply device 1 places the bobbins 5 on the tray 6. The delivery device 2 moves the tray 6 using a belt conveyor or the like. Thus, the tray 6 carrying the bobbins 5 is delivered to the automatic winding machine 110. After separating the yarn end from the yarn layer on the surface of the bobbin 5, the lead-out device 3 performs a process of winding the yarn end around the core tube and inserting it into the inside of the core tube. It should be noted that the process performed by the lead-out device 3 in this embodiment is just one example, and the process of the lead-out device 3 may vary depending on the processing content on the automatic winding machine 110 side.

[0052] like Figure 1As shown, the delivery device 2 has a first receiving path 101, a second receiving path 102, a delivery path 103, and a return path 104. The first receiving path 101 and the second receiving path 102 are paths for receiving bobbins 5 from the supply device 1. In this embodiment, since the exchange of bobbins 5 from the supply device 1 is performed by two systems, there are also two systems (first receiving path 101 and second receiving path 102) on the receiving side. The delivery path 103 is connected downstream of the first receiving path 101 and the second receiving path 102. The delivery path 103 is the path for delivering the tray 6 carrying the bobbins 5 to the automatic winding machine 110. The return path 104 is the path for returning the core tube after the yarn winding is completed. The core tube is extracted by an extraction device (not shown). The first receiving path 101 and the second receiving path 102 are connected downstream of the return path 104 via a path switching unit 105. The path switching unit 105 is a component capable of switching paths. Specifically, the path switching unit 105 can switch between a state where the tray 6 is transported to the first receiving path 101 and a state where the tray 6 is transported to the second receiving path 102. For example, when the first receiving path 101 is full of the tray 6, the path switching unit 105 transports the tray 6 to the second receiving path 102. Alternatively, the path switching unit 105 may also include a motor and a lever (not shown in the figure). The lever is moved by the power generated by the motor, enabling the switching between the two states.

[0053] The automatic winding machine 110 has a plurality of take-up units 111. The take-up units 111 are arranged in a predetermined direction. The delivery path 103 has branches that deliver trays 6 containing bobbins 5 to each individual take-up unit 111. Each take-up unit 111 takes up the yarn wound on the bobbin 5 to form a package.

[0054] Next, refer to Figures 2 to 10 The structure of the supply device 1 will be described in detail below. In the following description, the direction of the conveying tube 5 will be referred to as the conveying direction, and the direction orthogonal to the conveying direction on the horizontal plane will be referred to as the width direction. It should be noted that in the entire supply device 1, the conveying direction can be a single direction, or the conveying direction can change midway.

[0055] like Figure 2 As shown, the supply device 1 has a housing 1a. Various components constituting the supply device 1 are mounted and supported in the housing 1a. A footrest 1b is disposed on the outer surface of the housing 1a in the width direction. The footrest 1b is a component for the operator to place their feet. By placing their feet on the footrest 1b, the operator's viewpoint is raised. Therefore, the operator can easily inspect the bobbin 5 being transported by the supply device 1, or easily inspect the status of the various components constituting the supply device 1.

[0056] like Figure 2As shown, the supply device 1 includes a delivery device 11, a transport unit 12, a sorting unit 13, a conveying unit 14, an orientation adjustment unit 15, and a transfer unit 16.

[0057] The delivery device 11 delivers a plurality of tubes 5 (tube sets) contained in the container 7 to the conveying unit 12. Delivery refers to supplying an object to a downstream component. Specifically, such as... Figure 3 or Figure 4 As shown, the delivery device 11 includes a container mounting section 21, a rotating body 22, and a delivery motor 23. A container 7 is mounted on the container mounting section 21. The rotating body 22 is capable of rotating about a rotation center axis. The container mounting section 21 is fixed to the rotating body 22. The rotating body 22 is composed of… Figure 4 The delivery motor 23 shown is driven to rotate. Therefore, by driving the delivery motor 23 while the container 7 is mounted on the container mounting section 21, the orientation of the container 7 can be changed. Since the upper part of the container 7 is open, by tilting the container 7 downwards, the tube 5 contained within the container 7 can be delivered to the transport section 12.

[0058] It should be noted that changing the orientation of container 7 to deliver the tube 5 is one example. For example, a conveyor or robot can also be used to deliver the tube 5 to the handling unit 12. In this case, the conveyor or robot is equivalent to a "delivery device".

[0059] The transport unit 12 transports the bobbin 5 delivered by the delivery device 11 to the separation unit 13. In this embodiment, the transport unit 12 is a descending ramp that transports the bobbin 5 by its own weight. A descending ramp is a surface that slopes downwards as it approaches the downstream side. It should be noted that the transport unit 12 is not limited to a descending ramp, and may also be a transport device such as a belt conveyor.

[0060] like Figure 2 As shown, the transport unit 12 includes an upstream transport unit 30, a first downstream transport unit 40, and a second downstream transport unit 50. The first downstream transport unit 40 is a portion that branches off from the downstream end of the upstream transport unit 30 in a first direction in the width direction, and the second downstream transport unit 50 is a portion that branches off from the downstream end in a second direction in the width direction. As will be described later, there are various arrangements for implementing the transport unit 12.

[0061] The upstream transport section 30 includes a front upstream transport section 31, a rear upstream transport section 33, and an upstream restriction section 35.

[0062] The upstream transport section 31 receives and transports the tube 5 delivered by the delivery device 11. The upstream transport section 31 has an inclined surface for mounting the tube 5 and an upstream guide section 32 that restricts the position of the tube 5 in the width direction. Figure 2 As shown, the upstream guide section 32 has a shape that narrows in width as it approaches the downstream.

[0063] The downstream upstream transport section 33 is located downstream of the upstream transport section 31, and transports the bobbin 5 to the branch section of the transport section 12. The downstream upstream transport section 33 has an inclined surface for mounting the bobbin 5 and a downstream upstream guide section 34 that restricts the position of the bobbin 5 in the width direction. Figure 2 As shown, the upstream guide portion 34 of the rear section has a shape that expands in the width direction as it approaches the downstream.

[0064] The upstream guide section 34 extends in width as it approaches the downstream end, thereby increasing the number of tubes 5 that can be stored in the upstream transport section 33. Furthermore, due to the downstream branch of the upstream transport section 33, extending the downstream end of the upstream guide section 34 can, to some extent, expand the width of the two downstream transport sections. Additionally, both the first and second sides of the upstream guide section 34 in the width direction are inclined surfaces (in other words, conical or V-shaped). Therefore, using the upstream guide section 34 on the first side in the width direction facilitates guiding the tubes to the first downstream transport section 40. Similarly, using the upstream guide section 34 on the second side in the width direction facilitates guiding the tubes to the second downstream transport section 50.

[0065] If the upstream guide section 32 is shaped to expand in width as it approaches the downstream direction, the width of the upstream transport section 30 becomes excessive from the overall perspective, which also affects the size of the device. In this embodiment, the upstream guide section 32 narrows in width as it approaches the downstream direction. As a result, the downstream upstream guide section 34 can expand in width, and excessive device size is prevented. However, the shapes of the upstream guide section 32 and the downstream upstream guide section 34 are merely examples. For instance, they could be inclined on only one side in the width direction, while the other side is parallel to the transport direction. Alternatively, the first and second sides in the width direction of the upstream guide section 32 or the downstream upstream guide section 34 could be parallel to the transport direction.

[0066] The upstream restrictor 35 is disposed between the upstream transport section 31 and the downstream upstream transport section 33. The upstream restrictor 35 can be switched between a state where the transport of the cylinder 5 is restricted and a state where the restriction is lifted. Specifically, as follows... Figure 2 As shown, the tube 5 can be placed in the upstream limiting section 35. Furthermore, a step exists between the front upstream transport section 31 and the rear upstream transport section 33. This step restricts the transport of the tube 5 to the rear upstream transport section 33. This is achieved by driving... Figure 4 The upstream cylinder 36 shown, the upstream limiting part 35 as shown Figure 3 It moves up and down as shown. As a result, the cylinder 5 can cross the step. In other words, by moving up and down the upstream restrictor 35, the restriction on transportation is lifted, thereby allowing the cylinder 5 to be transported.

[0067] The supply device 1 in this embodiment is equipped with various actuators such as motors and cylinders. These actuators are just one example; various actuators can be used as long as the required power can be provided.

[0068] Additionally, a cutter and a suction device (not shown) are arranged near the upstream restrictor 35. The cutter and suction device are arranged, for example, adjacent to the upstream of the upstream restrictor 35, or adjacent to the downstream of the upstream restrictor 35. The cutter reciprocates up and down integrally with the upstream restrictor 35. With this structure, the yarn unwound from the bobbin 5 can be cut using the cutter and attracted using the suction device.

[0069] It should be noted that the structure of the upstream limiting section 35 is one example; for example, it could also be a structure that uses a gate member to switch between the closed and open states of the transport path. Furthermore, the cut-off device and the suction device are not essential components and can be omitted.

[0070] exist Figure 5 The diagram shows a front view of the upstream limiting section 35 (in other words, a view observed in the transport direction). Figure 5 As shown, a plurality of grooves are formed in the upstream limiting portion 35. The aforementioned cutter can also be configured to cut the yarn entering the grooves. Furthermore, in a frontal view, the upper end (outline) of the upstream limiting portion 35 includes a portion inclined relative to the width direction. This allows the bobbin 5 placed in the upstream limiting portion 35 to move easily and flow downstream without becoming stuck in the upstream limiting portion 35. In particular, in Figure 5 In the middle (i.e., when viewed in the transport direction), the upper end of the upstream restricting portion 35 is inclined in the entire width direction as it extends upward toward the center of the width direction. That is, the upper end of the outline of the upstream restricting portion 35 includes a portion that extends upward toward the center of the width direction from a first side and another portion that extends upward toward the center of the width direction from a second side. Therefore, a tube 5 located closer to the first side than the center of the width direction can be dropped and transported to the first downstream transport portion 40 located on the first side. Similarly, a tube 5 located closer to the second side than the center of the width direction can be dropped and transported to the second downstream transport portion 50 located on the second side. Therefore, a device for distributing the tube 5 in the width direction may not be provided upstream or downstream of the upstream restricting portion 35.

[0071] exist Figure 6 The diagram shows a top view (in other words, a view observed in the vertical direction) of the upstream limiting section 35. Figure 6As shown, the outline of the upstream end of the upstream limiting portion 35 includes a portion inclined relative to the width direction. Therefore, compared to the case where the upstream end of the upstream limiting portion 35 is parallel to the width direction, the amount of the tube 5 placed on the upstream limiting portion 35 can vary. In particular, in this embodiment, the upstream end is inclined upstream along the entire width direction as it approaches the center. That is, the upstream end of the outline of the upstream limiting portion 35 includes a portion inclined upstream as it approaches the center from a first side in the width direction, and a portion inclined upstream as it approaches the center from a second side in the width direction. Therefore, as explained at the upper end of the upstream limiting portion 35, the tube 5 can be transported on a first side and a second side. Therefore, a device for distributing the tube 5 in the width direction may not be provided upstream or downstream of the upstream limiting portion 35.

[0072] It should be noted that the shape of the upstream limiting portion 35 is just one example, and the aforementioned inclination may not be present. Furthermore, the upstream limiting portion 35 being inclined along its entire width is just one example, and it may also include a portion that is not inclined. The aforementioned groove is not mandatory and can be omitted. Additionally, the reciprocating motion of the upstream limiting portion 35 is not limited to the vertical direction, but can also be diagonally upward or downward. Specifically, the upstream limiting portion 35 may also reciprocate towards the downstream direction as it approaches the upper direction.

[0073] Next, the portion of the transport section 12 that is downstream of the upstream transport section 30 will be described. At the downstream end of the upstream transport section 30 (the downstream upstream transport section 33), the transport section 12 branches into a first downstream transport section 40 on a first side in the width direction and a second downstream transport section 50 on a second side. For example... Figure 2 As shown, the first downstream transport section 40 has a first limiting section 41. The second downstream transport section 50 has a second limiting section 51.

[0074] The basic structure and operation of the first limiting unit 41 are similar to those of the upstream limiting unit 35, therefore the description is simplified. That is, the first limiting unit 41... Figure 4 The first cylinder 42 shown reciprocates in the vertical direction. During the reciprocating motion of the first limiting part 41, the cylinder 5 is in a state where it is transported downstream over the step (the limiting state is lifted). During the period when the first limiting part 41 stops, the cylinder 5 is in a state where it is restricted from transporting over the step. Similarly, the second limiting part 51... Figure 4The second cylinder 52 shown reciprocates in the vertical direction. During the reciprocating motion of the second limiting part 51, the cylinder 5 is in a state where it is transported downstream over the step (the limiting state is lifted). During the period when the second limiting part 51 stops, the cylinder 5 is in a state where it cannot overcome the step and its transport is restricted. Thus, in this embodiment, the first cylinder 42, which serves as the drive unit of the first limiting part 41, and the second cylinder 52, which serves as the drive unit of the second limiting part 51, are separate. Therefore, the first limiting part 41 and the second limiting part 51 can operate independently. As a result, as will be described later, the cylinder 5 can be transported only to one side, the first side or the second side.

[0075] It should be noted that the first limiting part 41 and the second limiting part 51 can also be an integral structure. In this case, the cylinders on the drive side can be shared, and the first limiting part 41 and the second limiting part 51 can also be an integral structure. In this case, for example, by performing a process such as stopping the transport of only one of the first side and the second side, it is possible to operate only one of the first side and the second side.

[0076] In this embodiment, the first limiting part 41 and the second limiting part 51 hold and transport the tube 5, and switch between a state where the transport of the tube 5 is restricted and a state where the restriction is lifted. Alternatively, the function of holding and transporting the tube 5 can be removed from the first limiting part 41 and the second limiting part 51. In this case, the first limiting part 41 and the first cylinder 42 are, for example, gate members capable of switching between opening and closing.

[0077] In this embodiment, no wall serving as a boundary is provided between the first limiting part 41 and the second limiting part 51. Therefore, it is less likely that the tube 5 will be confined within a narrow area, and thus less likely to become blocked. However, a wall serving as a boundary may also be provided. Furthermore, the cutter and suction device may be respectively provided in the first limiting part 41 and the second limiting part 51, similar to the upstream limiting part 35.

[0078] The combined shape of the first limiting part 41 and the second limiting part 51 is similar to the shape of the upstream limiting part 35, and can achieve the same effect. Specifically, Figure 7 A front view of the first limiting part 41 and the second limiting part 51 is shown. Figure 7As shown, a plurality of grooves are formed on the first limiting portion 41 and the second limiting portion 51. Furthermore, in a frontal view, the upper ends (outlines) of the first limiting portion 41 and the second limiting portion 51 each include portions inclined relative to the width direction. Specifically, the first limiting portion 41 and the second limiting portion 51 are shaped to increase in height as they approach the center in the width direction. The effect of these shapes is the same as that of the upstream limiting portion 35. Additionally, although not shown in the figure, the outlines of the upstream ends of the first limiting portion 41 and the second limiting portion 51 also include portions inclined relative to the width direction when viewed from above. Specifically, the first limiting portion 41 and the second limiting portion 51 are inclined as a whole, causing the upstream ends to extend upstream as they approach the center in the width direction. The effect of these shapes is the same as that of the upstream limiting portion 35.

[0079] In this embodiment, the first downstream transport section 40 and the second downstream transport section 50 are arranged in the width direction. The first downstream transport section 40 and the second downstream transport section 50 have the same shape, or are symmetrical about the center in the width direction. This arrangement is just one example and can be modified as follows: For example, at the branch point, the transport direction of the first downstream transport section 40 and the transport direction of the second downstream transport section 50 may be different. For example, the first downstream transport section 40 and the second downstream transport section 50 may also be arranged in a V-shape. Alternatively, the upstream transport section 30, the first downstream transport section 40, and the second downstream transport section 50 may also be arranged in a T-shape.

[0080] like Figure 8 As shown, a first storage sensor 71 and a second storage sensor 72 are disposed in the upstream transport section 33. The first storage sensor 71 and the second storage sensor 72 are equivalent to "upstream sensors". The first storage sensor 71 and the second storage sensor 72 are photoelectric sensors, each having a light-emitting part and a light-receiving part. Based on whether the light-receiving part receives light from the light-emitting part, the sensor detects light on the optical path (…). Figure 8 (In the direction of the arrow) whether there is an object. It should be noted that the photoelectric sensor is just one example; the first sensor 71 or the second sensor 72 can also use a camera, contact sensor, weight sensor, etc. to detect the presence or absence of an object.

[0081] The first storage sensor 71 detects whether there are any tubes 5 in the vicinity of the first limiting part 41 and the second limiting part 51, upstream of the first limiting part 41. Furthermore, since the upstream transport section 33 is an inclined plane, the tubes 5 present in the upstream transport section 33 will generally accumulate sequentially from the downstream end. Therefore, even if there are a small number of tubes 5 in the upstream transport section 33, the first storage sensor 71 detects the tubes 5.

[0082] The second storage sensor 72 is positioned upstream of the first storage sensor 71 and near the upstream restriction section 35. Alternatively, the first storage sensor 71 is positioned downstream of the center of the transport path of the upstream transport section 33, while the second storage sensor 72 is positioned further upstream. As described above, since the tubes 5 accumulate from the downstream end in the upstream transport section 33, a greater number of tubes 5 remain in the upstream transport section 33 when the second storage sensor 72 detects them.

[0083] Based on the detection results of the first storage sensor 71 and the second storage sensor 72, the retention status of the tube 5 in the upstream transport section 33 (upstream transport section 30) can be determined. Therefore, the first storage sensor 71 and the second storage sensor 72 are equivalent to "upstream sensors". The method of utilizing the detection results of the first storage sensor 71 and the second storage sensor 72 will be described later.

[0084] The individualization unit 13 separates the plurality of tubes 5 transported by the transport unit 12 into individual tubes 5. In other words, the transport unit 12 in this embodiment transports a plurality of tubes 5 in a concentrated manner (more precisely, in a non-uniform arrangement), therefore, individualization is required for delivery to the delivery device 2. The individualization unit 13 has a first individualization unit 43 and a second individualization unit 53. The first individualization unit 43 individualizes the tubes 5 transported by the first downstream transport unit 40. The second individualization unit 53 individualizes the tubes 5 transported by the second downstream transport unit 50. In this embodiment, the first individualization unit 43 and the second individualization unit 53 are arranged symmetrically with respect to a line passing through the center of the width direction of the upstream transport unit 30. This is an example; the first individualization unit 43 and the second individualization unit 53 may also be arranged in the same orientation.

[0085] The first individual component 43 and the second individual component 53 have substantially the same structure; therefore, the corresponding components will be labeled with the same reference numerals below, and will be described together. For example... Figure 3 and Figure 9 As shown, the first individualization unit 43 uses a conveyor arranged in the vertical direction to individualize the bobbins 5. The first individualization unit 43 has a belt 61. The belt 61 is a strip-shaped (sheet-shaped) component that is arranged in a ring between two rotating rollers 62 arranged in the vertical direction. The upper rotating roller 62 is driven to rotate by a motor. Here, the motor of the first individualization unit 43 is referred to as the first motor 63, and the motor of the second individualization unit 53 is referred to as the second motor 64. The first motor 63 and the second motor 64 are equivalent to the "drive unit" for driving the individualization unit 13. The first motor 63 and the second motor 64 are, for example, stepper motors. The rotation of the output shaft of the stepper motor is transmitted to the upper rotating roller 62 via a drive transmission belt or the like. Thus, the belt 61 is driven cyclically.

[0086] A support platform 65 is provided on the outer side of the belt 61. The support platforms 65 are provided at equal intervals along the length of the belt 61. The support platforms 65 move integrally with the belt 61. A bobbin 5 is placed on the support platform 65. Thus, the support platform 65 supports and transports the placed bobbin 5. The support platform 65 has a rectangular surface to accommodate the bobbin 5 in a tilted position. This rectangular support platform 65 is installed on the belt 61 with its length along the width direction of the belt 61. Furthermore, the depth of the support platform 65 is such that two bobbins 5 cannot be placed side-by-side. The first separation unit 43, by cyclically driving the belt 61, places the bobbins 5 one by one onto the support platform 65 and transports the bobbins 5 upwards. In this way, a plurality of bobbins 5 can be separated.

[0087] Furthermore, when two or more tubes 5 are placed on a support platform 65 in a vertically overlapping manner, the tubes 5 are individually separated by the following structure: The first separation section 43 has a separation member 67. The separation member 67 is a member capable of contacting the tubes 5 transported by the support platform 65. The separation member 67 is provided along the transport direction of the tubes 5 transported by the support platform 65, causing one or more tubes 5 to fall from the support platform 65 and separate, so that one tube 5 is placed on the support platform 65. In this embodiment, the separation member 67 is made of metal wire. However, as long as it can contact the tubes 5 and cause the tubes 5 to fall from the support platform 65, the separation member 67 is not limited to being made of metal wire.

[0088] Additionally, a sensor for detecting the bobbin 5 transported by the support platform 65 is disposed in the first individualization section 43. Here, the sensor disposed in the first individualization section 43 is referred to as the first individualization sensor 73, and the sensor disposed in the second individualization section 53 is referred to as the second individualization sensor 74. The first individualization sensor 73 and the second individualization sensor 74 are contact sensors. The first individualization sensor 73 and the second individualization sensor 74 are positioned at a location passing through the slit formed in the support platform 65, not in contact with the support platform 65, but in contact with the bobbin 5 placed on the support platform 65. It should be noted that the first individualization sensor 73 and the second individualization sensor 74 are not limited to contact sensors; for example, they can also be photoelectric sensors. The first individualization sensor 73 can detect the bobbin 5 present downstream of the first side, and is therefore equivalent to a "first downstream sensor". The second individualization sensor 74 can detect the bobbin 5 present downstream of the second side, and is therefore equivalent to a "second downstream sensor". Alternatively, the first downstream sensor can also be a photoelectric sensor that detects the bobbin 5 located downstream of the first restriction section 41 and upstream of the first individualization section 43. The second downstream sensor can also be a photoelectric sensor that detects the tube 5 located downstream of the second limiting section 51 and upstream of the second individualizing section 53. Alternatively, a camera or a contact sensor can be used instead of a photoelectric sensor. Either the first downstream sensor or the second downstream sensor described above can be used for the control described later.

[0089] The conveying unit 14 transports the individualized bobbins 5 one by one by the individualization unit 13. The conveying unit 14 includes: a first conveying unit 45 that transports the bobbins 5 individualized by the first individualization unit 43; and a second conveying unit 55 that transports the bobbins 5 individualized by the second individualization unit 53. Figure 10 As shown, the first conveying section 45 and the second conveying section 55 are structures formed by arranging a plurality of belt conveyors along the transport direction. Furthermore, as... Figure 9 As shown, the first conveying section 45 and the second conveying section 55 can not only convey the tube 5 to the junction section 16, but also transport the tube 5 in the opposite direction.

[0090] Additionally, a plurality of conveying sensors are provided in the conveying section 14 to detect the conveyed bobbin 5. Here, the conveying sensor provided in the first conveying section 45 is referred to as the first conveying sensor 75, and the conveying sensor provided in the second conveying section 55 is referred to as the second conveying sensor 76. The first conveying sensor 75 and the second conveying sensor 76 are photoelectric sensors. However, the first conveying sensor 75 and the second conveying sensor 76 may also be cameras or contact sensors. Since a plurality of the first conveying sensor 75 and the second conveying sensor 76 are provided, information related to the amount of bobbin 5 present in the first conveying section 45 and the first orientation adjustment section 46 can be detected. The first conveying sensor 75 can detect the bobbin 5 present downstream on the first side, and is therefore equivalent to a "first downstream sensor". The second conveying sensor 76 can detect the bobbin 5 present downstream on the second side, and is therefore equivalent to a "second downstream sensor".

[0091] The orientation adjustment unit 15 aligns the orientation of the bobbin 5 transported by the conveying unit 14 and conveys it to the transfer unit 16. The orientation adjustment unit 15 includes: a first orientation adjustment unit 46, which aligns the orientation of the bobbin 5 transported by the first conveying unit 45; and a second orientation adjustment unit 56, which aligns the orientation of the bobbin 5 transported by the second conveying unit 55. The first orientation adjustment unit 46 and the second orientation adjustment unit 56 determine whether the downstream end of the bobbin 5 is the upper or lower end of the bobbin 5. When the downstream end of the bobbin 5 is the lower end, the first orientation adjustment unit 46 and the second orientation adjustment unit 56 maintain the orientation of the bobbin 5. When the downstream end of the bobbin 5 is the upper end, the first orientation adjustment unit 46 and the second orientation adjustment unit 56 change the orientation of the bobbin 5 by 180 degrees. Therefore, when the transfer unit 16 transfers the bobbin 5 to the delivery device 2, the lower end of the bobbin 5 can be transferred to the tray 6 with the lower end facing down. Furthermore, the first orientation adjustment unit 46 and the second orientation adjustment unit 56 have the function of discharging the blockage in the cylinder 5 when it is blocked during the adjustment of the cylinder 5's direction. It should be noted that the first orientation adjustment unit 46 and the second orientation adjustment unit 56 are known devices, therefore detailed descriptions are omitted.

[0092] The transfer section 16 transfers the tube 5, which has passed through the orientation adjustment section 15, to the delivery device 2. The transfer section 16 has a first transfer section 47 and a second transfer section 57. The first transfer section 47 transfers the tube 5, which has passed through the first orientation adjustment section 46, to the tray 6 located on the first receiving path 101. The second transfer section 57 transfers the tube 5, which has passed through the second orientation adjustment section 56, to the tray 6 located on the second receiving path 102.

[0093] Since the first receiving path 101 and the second receiving path 102 are different paths, the positions of the first junction 47 and the second junction 57 are also different. In this embodiment, the first receiving path 101 is located further away from the supply device 1 than the second receiving path 102. Therefore, the transport distance on the first side of the supply device 1 (specifically, the transport distance from the first individualization section 43 to the first junction 47) is longer than the transport distance on the second side of the supply device 1 (specifically, the transport distance from the second individualization section 53 to the second junction 57). In other words, the number of tubes 5 that can be stored on the first side of the supply device 1 is greater than the number of tubes 5 that can be stored on the second side of the supply device 1.

[0094] On the other hand, in the delivery device 2, the first receiving path 101 is used preferentially over the second receiving path 102. In other words, when the preparation device 100 is activated, the number of tubes 5 handed over to the pallet 6 of the first receiving path 101 per unit time is greater than the number of tubes 5 handed over to the pallet 6 of the second receiving path 102 per unit time. The reason for this will be explained below. Here, the length from the position P0 of the path switching unit 105 to the first receiving position P1 of the tube 5 received in the first receiving path 101 is called the first path length. The length from the position P0 of the path switching unit 105 to the second receiving position P2 of the tube 5 received in the second receiving path 102 is called the second path length. Figure 1 As shown, the length of the first path is less than the length of the second path. That is, in the first receiving path 101, since the distance from position P0 to the first receiving position P1 is shorter, it is easier to supply the tube 5 to fill the space between them. As a result, the first receiving path 101 is used preferentially over the second receiving path 102.

[0095] In other words, in this embodiment, it is preferable that a larger quantity of tubes 5 can be prepared in the supply device 1 on the first side of the first receiving path 101 that is preferred for use. However, this is just one example, and the relationship between priority and the transport distance of the supply device 1 can also be reversed.

[0096] The control unit 70 comprises one or more computers. Each computer has a processing unit, a primary storage device, a secondary storage device, and a communication device. The processing unit, such as a CPU, is capable of performing arithmetic operations. The primary storage device is RAM or a cache memory, which allows for high-speed reading and writing of data via the processing unit. The secondary storage device is an SSD, HDD, or flash memory, which pre-stores the programs and data required for control. By reading the programs from the primary storage device and executing them via the processing unit, the control unit 70 performs various processes related to the supply device 1 or the delivery device 2. Figure 4 As shown, the control unit 70 acquires the detection results from the various sensors described above. Figure 4As shown, the control unit 70 controls the various drive units described above.

[0097] Next, refer to Figures 11 to 14 The control performed by the control unit 70 will be explained.

[0098] In the following description, part or all of the device from the first downstream transport section 40 to the first transfer section 47 will be collectively referred to as the "first-side device", and part or all of the device from the second downstream transport section 50 to the second transfer section 57 will be collectively referred to as the "second-side device".

[0099] The tube transfer of the supply device shown in Patent Document 1 is a system. Therefore, if a malfunction occurs at any point from the individualization section to the transfer section, or if any part stops due to the operator's judgment, the supply device itself will stop. As a result, tubes cannot be supplied to the delivery device, thus potentially reducing operational efficiency.

[0100] In contrast, the supply device 1 of this embodiment has a device on a first side and a device on a second side, thus creating two systems for the path. Therefore, even if only one of the devices on the first side and the second side stops operating, the other can continue operating. Therefore, the supply of the bobbin 5 is not stopped. It should be noted that since the operation of the delivery device 2 continues even when only one side stops operating, corresponding processing is also required. Hereinafter, refer to... Figure 11 The details of this process will be explained.

[0101] First, the control unit 70 determines whether only the operation of the first-side device or the second-side device has stopped (S101). Hereinafter, we will assume that the first-side device has stopped operating. Since the stopping of operation is controlled by the control unit 70, the control unit 70 can determine that the operation of the first-side device has stopped based on the control history. Even if the operation of the first-side device has stopped, the control unit 70 continues the operation of the remaining side (i.e., the second-side device) (S102). At this time, the control unit 70 also continues the operation of the delivery device 2. Therefore, even if a malfunction occurs in the first-side device, the supply of the bobbin 5 can continue using the second-side device.

[0102] Depending on when the device on the first side stops operating, the remaining tube 5 may sometimes be located in the device on the first side. This remaining tube 5 is stored until the device on the first side resumes operation. To avoid this, in this embodiment, the control unit 70 transports the tube 5 stored in the stopped device on the first side to the upstream transport unit 30 (S103). Specifically, the control unit 70 drives the first conveying unit 45 in the opposite direction to normal, thereby transporting the tube 5 above the upstream transport unit 30 (e.g., the downstream upstream transport unit 33 located near the first limiting unit 41), causing the tube 5 to fall. This allows the tube 5 stored in the stopped device on the first side to be provided to the operating device on the second side.

[0103] Additionally, in order to more reliably supply the return tube 5 to the operating device on the second side, a device for bringing the return tube 5 closer to the second side (e.g., a rod disposed in the downstream upstream transport section 33) may be provided. It should be noted that step S103 is not necessary and can be omitted.

[0104] Next, the control unit 70 determines whether a tube blockage has occurred in the orientation adjustment unit 15 (S104). The control unit 70 controls the orientation adjustment unit 15, and therefore this determination can be made based on feedback from the orientation adjustment unit 15. For example, if the operation of the device on the first side stops due to a tube blockage, operation on one side and the tube blockage occur simultaneously. Alternatively, a tube blockage may also occur in the operating second orientation adjustment unit 56.

[0105] In the event of a tube blockage in the orientation adjustment unit 15, as described above, the orientation adjustment unit 15 discharges the blocked tube 5. The discharged tube 5 may become lodged in the belt conveyor of the delivery device 2. Therefore, it is preferable to stop the delivery device 2 at the moment the tube 5 is discharged. The control unit 70 continues operation of the delivery device 2 if it determines that no tube blockage has occurred in the orientation adjustment unit 15 (S105). On the other hand, the control unit 70 stops operation of the delivery device 2 if it determines that a tube blockage has occurred in the orientation adjustment unit 15 (S106). This prevents abnormalities in the belt conveyor of the delivery device 2 caused by tubes discharged from the orientation adjustment unit 15. It should be noted that the process of the control unit 70 stopping the operation of the delivery device 2 when a tube blockage occurs is just one example. Strictly speaking, it is sufficient to stop the delivery device 2 as soon as the tube blockage is cleared and the tube 5 is discharged. Furthermore, the clearing of tube blockages is sometimes also performed by the operator operating the orientation adjustment unit 15. In such a situation, the operator can also use the adjustment unit 15 to issue a discharge instruction for the tube 5 as a trigger, and the control unit 70 will stop the operation of the delivery device 2.

[0106] It should be noted that when the control unit 70 stops the operation of the delivery device 2, it is preferable to stop a portion of the operating second-side device (specifically, the second junction 57). In addition, in step S104, the control unit 70 may also determine whether the "bottom tube blockage removal operation has started" instead of determining whether "bottom tube blockage has occurred".

[0107] When the operation of the delivery device 2 is stopped, the control unit 70 determines whether the blockage in the bobbin toward the adjustment unit 15 has been cleared (S107). According to the command of the control unit 70, the blockage is cleared by performing a bobbin clearing operation on the adjustment unit 15. Therefore, the control unit 70 makes this determination based on control history records or feedback from the adjustment unit 15. If the control unit 70 determines that the bobbin blockage has been cleared, it restarts the operation of the delivery device 2 (S108).

[0108] Next, refer to Figure 12 The handling of the storage status of the cylinder 5 based on the first and second sides will be explained.

[0109] In this embodiment, the first limiting part 41 and the second limiting part 51 can operate independently, and the first individualizing part 43 and the second individualizing part 53 can operate independently. In this embodiment, the storage status of the tube 5 is used as information for enabling these devices to operate independently. The control unit 70 first calculates the storage status of the tube 5 (S201).

[0110] Here, the storage status of the bobbin 5 refers to information based on the number of bobbins 5 stored (present) in the device on the first or second side. For example, if there are a large number of bobbins 5 in the first separation unit 43 or the first conveying unit 45, it is determined that there are a large number of bobbins 5 stored on the first side. It should be noted that the specific number of bobbins 5 can also be determined based on the number of sensors or the type of sensors. However, in this embodiment, the detailed information up to this point is not known, but rather it is estimated whether the storage status of the bobbins 5 exceeds a certain benchmark.

[0111] Specifically, the control unit 70 calculates the storage status of the bobbin 5 in the first-side device based on the detection results of the first individual sensor 73 and the first conveying sensor 75. For example, the storage status of the bobbin 5 can be calculated based on the number of times the first individual sensor 73 detected the bobbin 5 in the past few seconds, and the detection history of the bobbin 5 by the plurality of first conveying sensors 75. It should be noted that the storage status of the bobbin 5 can also be calculated based on only one of the first individual sensor 73 and the first conveying sensor 75. This also applies to the second-side device.

[0112] The control unit 70 independently controls the first restriction unit 41 and the second restriction unit 51 based on the storage status of the tubes 5 in the first and second side devices (S202). The control of the first restriction unit 41 and the second restriction unit 51 refers to the presence or absence of reciprocating motion or the operating speed. The faster the operating speed, the more reciprocating motions occur per unit time. As a result, the number of tubes 5 passing through the first restriction unit 41 or the second restriction unit 51 per unit time is easily increased. In this embodiment, the first restriction unit 41 is controlled based on the storage status of the tubes 5 in the first side device, and the second restriction unit 51 is controlled based on the storage status of the tubes 5 in the second side device.

[0113] For example, when there is a large amount of tubing 5 stored in the device on the first side (e.g., when the first individual sensor 73 detects tubing 5), the necessity to urgently supply tubing 5 to the device on the first side is low. Therefore, the control unit 70 stops the first limiting unit 41 or slows down its operation. Furthermore, if a large amount of tubing 5 is detected during the rising of the first limiting unit 41, the control unit 70 can also stop the rising action of the first limiting unit 41 midway. This easily avoids the situation where tubing 5 is being supplied further when there is a large amount of tubing 5 stored. Additionally, if the situation of a large amount of tubing 5 stored is eliminated, the control unit 70 can also restart the rising action of the first limiting unit 41. It should be noted that stopping the rising action of the first limiting unit 41 midway is one example; for example, the rising action of the first limiting unit 41 can also be canceled, and the first limiting unit 41 can be lowered. The above control is not limited to the first side; the same control is performed on the second side as well.

[0114] On the other hand, when the number of tubes 5 stored in the device on the first side is low, it becomes necessary to supply tubes 5 to the device on the first side. Therefore, the control unit 70 restarts the reciprocating motion of the first limiting unit 41 or increases its operating speed. As a result, the storage status of the tubes 5 can be controlled within an appropriate range. The above control is not limited to the first side, but is also performed on the second side.

[0115] As described above, the first receiving path 101 is used preferentially over the second receiving path 102. Furthermore, in this embodiment, the control unit 70 controls the operation of the first limiting unit 41 (which is the preferred side) to be faster than the operation of the second limiting unit 51. This reduces the frequency of supplying the tube 5 to the second individualization unit 53 via the second limiting unit 51. Therefore, from the point when the storage status of the tube 5 in the second-side device increases (specifically, from the point when the second individualization sensor 74 detects the tube 5) until the second limiting unit 51 stops, the tube 5 is less likely to be supplied to the second individualization unit 53. As a result, it is easier to avoid situations where the supply of tube 5 in the second-side device becomes excessive. Furthermore, the same effect can be achieved even when the storage status is detected without relying on the second individualization sensor 74, or when the second limiting unit 51 stops due to reasons other than the storage status.

[0116] A supplementary method is provided for comparing the operating speeds of the first limiting part 41 and the second limiting part 51. When the operating speeds of the first limiting part 41 and the second limiting part 51 are variable, for example, their normal operating speeds are compared. Alternatively, their operating speeds are compared when the storage conditions of the tubes are the same.

[0117] Next, the control unit 70 adjusts the transport speed of the first individualization unit 43 and the second individualization unit 53 separately based on the storage status of the tubes 5 in the first and second side devices (S203). In this embodiment, the transport speed of the first individualization unit 43 is controlled based on the storage status of the tubes 5 in the first side device, and the transport speed of the second individualization unit 53 is controlled based on the storage status of the tubes 5 in the second side device.

[0118] For example, when there are many spools 5 stored in the first-side device, the stored spools 5 can be transferred to the delivery device 2, thus reducing the need for emergency transport of the spools 5. Therefore, the control unit 70 reduces the transport speed of the first individualization unit 43. Specifically, it reduces the rotational speed of the first motor 63 and the moving speed of the support platform 65. This allows the first individualization unit 43 to operate stably. For example, it reduces the possibility of failure in individualizing the spools 5 in the first individualization unit 43. On the other hand, when there are few spools 5 stored in the first-side device, emergency transport of the spools 5 is needed to handle the transfer of the spools 5 to the delivery device 2. Therefore, the control unit 70 increases the transport speed of the first individualization unit 43. Specifically, it increases the rotational speed of the first motor 63 and the moving speed of the support platform 65. This allows the first individualization unit 43 to operate at high speed, quickly supplying the spools 5 to the first delivery unit 45.

[0119] In this embodiment, the first restricting part 41 and the first individualizing part 43 are controlled based on the storage status of the tubes 5 of the device on the first side. Alternatively, the first restricting part 41 and the first individualizing part 43 may be controlled based on the storage status of the tubes 5 of the device on the second side, or alternatively, based on the storage status of the tubes 5 on the first side. For example, if the storage status of the tubes 5 on the first side is compared with that on the second side and the first side is less, the operating speed of the first restricting part 41 may be faster than the operating speed of the second restricting part 51, or the transport speed of the first individualizing part 43 may be faster than the transport speed of the second individualizing part 53.

[0120] In this embodiment, both the downstream restricting section and the individualizing section 13 are controlled objects, but either one may be controlled. Alternatively, the downstream restricting section and the individualizing section 13 may be replaced, or the conveying section 14 may be controlled instead.

[0121] Next, refer to Figure 13 and Figure 14 The processing of detection results from various sensors based on the detection tube 5 is explained.

[0122] First, refer to Figure 13 The potential problems will be explained. The first storage sensor 71 and the second storage sensor 72 described above are used to detect the retention status of the bobbin 5 in the upstream transport section 33. For example, if both the first storage sensor 71 and the second storage sensor 72 detect the bobbin 5, it can be known that a large number of bobbins 5 are retained in the upstream transport section 33. In this case, the control unit 70 stops the reciprocating motion of the upstream restriction unit 35, thus inhibiting the supply of new bobbins 5 to the upstream transport section 33.

[0123] However, as Figure 13 As shown, when the device on the second side stops operating (especially when the second limiting part 51 stops), the tube 5 may become stuck around the second limiting part 51. Furthermore, due to the unbalanced state or jamming of the stuck tube 5, the tube 5 stuck in front of the second limiting part 51 may be unable to move to the first side. As a result, as... Figure 13 As shown, the bobbin 5 that is stuck in front of the second limiting section 51 will be detected by the first storage sensor 71 and the second storage sensor 72. Therefore, even if the device on the first side is operating and should be supplying bobbin 5 to the first side, a situation will occur where new bobbin 5 cannot be supplied from the upstream conveying section 31 because the downstream upstream conveying section 33 is determined to be full.

[0124] The control unit 70 in this embodiment performs [operations] to avoid such a situation. Figure 14The flowchart shown illustrates each process. The control unit 70 determines whether the first storage sensor 71 has detected the bobbin 5 (S301), and determines whether the second storage sensor 72 has detected the bobbin 5 (S302).

[0125] If the first storage sensor 71 or the second storage sensor 72 fails to detect the bobbin 5, the control unit 70 performs a reciprocating motion of the upstream restriction unit 35 (S307). As described above, when the first individual sensor 73 fails to detect the bobbin 5, the control unit 70 performs a reciprocating motion of the first restriction unit 41 (S202). Similarly, when the second individual sensor 74 fails to detect the bobbin 5, the control unit 70 performs a reciprocating motion of the second restriction unit 51 (S202). This allows the supply of bobbin 5 to areas where it is insufficient. In other words, based on the detection results of the first downstream sensor, the second downstream sensor, and the upstream sensor, the control unit 70 controls the restriction unit corresponding to the sensor that failed to detect the bobbin 5 to switch to a state where the restriction on the transport of the bobbin 5 is lifted.

[0126] If the first storage sensor 71 and the second storage sensor 72 detect the bobbin 5, the control unit 70 determines whether only one of the devices on the first side and the second side is operating (S303). As described above, the control unit 70 can determine whether the operation of the device on the first side or the second side has stopped based on the control history. Figure 13 The situation only occurs when one device is stopped while the other is in operation, therefore the control unit 70 makes this determination. Whether it is in operation refers to whether the stop is caused by abnormal stop, maintenance, etc. (in other words, a long-term stop). Alternatively, whether it is in operation can also refer to whether it is a temporary stop that may occur under various conditions. A temporary stop refers to, for example, in the delivery device 2, a stop caused by the pallet 6 not being moved to the second receiving path 102 because the first receiving path 101 has priority.

[0127] If it is determined that not only one of the devices on the first side and the second side is operating (for example, if it is determined that both the first side and the second side are operating), in principle, the control unit 70 stops the reciprocating motion of the upstream limiting unit 35 (S304). As a result, it is possible to prevent the further supply of the bobbin 5 to the downstream upstream conveying unit 33 when it is already in a full state.

[0128] If it is determined that only one of the devices on the first side and the second side is operating, the control unit 70 determines whether the storage condition of the bobbin 5 on the operating side is less than a threshold (S305). That is, even if it is assumed that there is bobbin 5 stuck upstream of the second limiting section 51, as long as there are enough bobbin 5 in the device on the first side, it is not necessary to immediately supply new bobbin 5 to the device on the first side. Therefore, if the storage condition of the bobbin 5 on the operating side is not less than the threshold, the control unit 70 also stops the reciprocating motion of the upstream limiting section 35 (S304).

[0129] Furthermore, if the storage condition of the cylinder 5 on the side determined to be in operation is below a threshold, it is considered that an incident has occurred. Figure 13 Therefore, the control unit 70 performs a retention-eliminating operation (S306) to eliminate the retention of the tube 5. The retention-eliminating operation may involve reciprocating the stopping side of the restrictor several times. As a result, the tube 5 moves, allowing the retained tube 5 to flow towards the operating side. Alternatively, the retention-eliminating operation may involve reciprocating the upstream restrictor 35. This supplies a new tube 5 to the downstream upstream conveying unit 33, thus breaking the balance of the retained tube 5 and eliminating the retention. Alternatively, the retention-eliminating operation may be an operation to eliminate the state of the tube 5 in the optical path of the second storage sensor 72. It should be noted that the retention-eliminating operation is not limited to these. For example, it may involve vibrating the downstream upstream conveying unit 33 to move the tube 5, or it may involve pressing the tube 5 using a pressing member (not shown in the diagram).

[0130] While performing the stagnation elimination operation, the control unit 70 implements the reciprocating motion of the upstream restriction unit 35 (S307). As a result, since the tube 5 is supplied to the downstream upstream conveying unit 33, the tube 5 can be supplied to the device on the operating side.

[0131] It should be noted that even when the reciprocating motion of the upstream limiting section 35 stops, the control section 70 restarts the reciprocating motion of the upstream limiting section 35 (S307) when the first storage sensor 71 or the second storage sensor 72 no longer detects the bobbin 5. Thus, when the bobbin 5 in the downstream upstream transport section 33 decreases from its full state, the bobbin 5 can be supplied to the downstream upstream transport section 33 again.

[0132] In this embodiment, both the first storage sensor 71 and the second storage sensor 72 are used to determine the state of the upstream transport unit 33. Alternatively, the same control can be achieved using only the second storage sensor 72. Or, if a single sensor is used at a different location instead of the first and second storage sensors 71, the same control can be achieved using the detection result of that sensor.

[0133] As described above, the supply device 1 of this embodiment includes a delivery device 11, a transport unit 12, a separation unit 13, a transfer unit 16, and a control unit 70. The delivery device 11 delivers a spool assembly representing a plurality of bobbins 5 wound with yarn. The transport unit 12 transports the spool assembly delivered by the delivery device 11. The separation unit 13 separates the spool assembly transported by the transport unit 12 into individual bobbins 5. The transfer unit 16 transfers the individualized bobbins 5 from the separation unit 13 downstream. The control unit 70 controls the transport unit 12, the separation unit 13, and the transfer unit 16. The transport unit 12 includes an upstream transport unit 30, a first downstream transport unit 40, and a second downstream transport unit 50. The upstream transport unit 30 receives and transports the spool assembly delivered by the transport device 11. The first downstream transport unit 40 transports the spool assembly via a branch path from the upstream transport unit 30. The second downstream transport section 50 transports the tube assembly via a path different from the first downstream transport section 40, branching off from the upstream transport section 30. The individualization section 13 has a first individualization section 43 and a second individualization section 53. The first individualization section 43 individualizes the tube assembly transported by the first downstream transport section 40. The second individualization section 53 individualizes the tube assembly transported by the second downstream transport section 50. The transfer section 16 has a first transfer section 47 and a second transfer section 57. The first transfer section 47 transfers the individualized tubes 5 from the first individualization section 43 downstream. The second transfer section 57 transfers the individualized tubes 5 from the second individualization section 53 downstream.

[0134] Therefore, since there are two of each of the conveying unit 12, the individualizing unit 13 and the handover unit 16, the supply of the cylinder 5 can continue even if any one of them malfunctions.

[0135] In the supply device 1 of this embodiment, the first downstream transport unit 40 has a first restriction unit 41 that switches between a state in which the transport of the bobbin assembly is restricted and a state in which the restriction is lifted. The second downstream transport unit 50 has a second restriction unit 51 that switches between a state in which the transport of the bobbin assembly is restricted and a state in which the restriction is lifted.

[0136] Therefore, the necessary amount of tubing 5 can be supplied to the first downstream conveying unit 40 and the second downstream conveying unit 50 according to the situation.

[0137] In the supply device 1 of this embodiment, the upstream transport section 30 includes a front upstream transport section 31, an upstream restriction section 35, and a rear upstream transport section 33. The front upstream transport section 31 receives and transports the tube assembly delivered by the delivery device 11. The upstream restriction section 35 is connected downstream of the front upstream transport section 31 and switches between a state where the transport of the tube assembly is restricted and a state where the restriction is lifted. The rear upstream transport section 33 is connected downstream of the upstream restriction section 35 and is located upstream of the first downstream transport section 40 and the second downstream transport section 50.

[0138] Therefore, upstream of the branch section, the amount of cylinder 5 supplied downstream can be adjusted.

[0139] The supply device 1 of this embodiment includes a first downstream sensor (first individualization sensor 73 or first conveying sensor 75, hereinafter the same), a second downstream sensor (second individualization sensor 74 or second conveying sensor 76, hereinafter the same), and an upstream sensor (first storage sensor 71 or second storage sensor 72, hereinafter the same). The first downstream sensor detects the tube 5 downstream of the first restriction section 41 in the first downstream transport section 40 or in the first individualization section 43. The second downstream sensor detects the tube 5 downstream of the second restriction section 51 in the second downstream transport section 50 or in the second individualization section 53. The upstream sensor detects the tube 5 in the upstream transport section 30. The control unit 70 controls the restriction section (upstream restriction section 35, first restriction section 41, or second restriction section 51, hereinafter the same) based on the detection results of the first downstream sensor, the second downstream sensor, and the upstream sensor.

[0140] Therefore, at least one of the various restriction parts can be controlled based on the conditions of both the upstream and downstream sides of the first restriction part 41 and the second restriction part 51.

[0141] In the supply device 1 of this embodiment, the direction orthogonal to the transport direction of the transport section 12 is set as the width direction on the horizontal plane. The restricting section switches between a state where the transport of the tube assembly is restricted and a state where the restriction is lifted by moving in the vertical direction, and the outline of the upstream end of the restricting section in the transport direction includes a portion that slopes upstream as it approaches the center in the width direction when viewed from above.

[0142] Therefore, it is possible to separate and transport multiple cylinders 5 to one side and the other side in the width direction.

[0143] In the supply device 1 of this embodiment, when viewed in the transport direction, the outline of the upper end of the restrictor in the transport direction includes a portion that slopes upward as it approaches the center in the width direction.

[0144] Therefore, it is possible to separate and transport multiple cylinders 5 to one side and the other side in the width direction.

[0145] The supply device 1 in this embodiment has a first cylinder 42 and a second cylinder 52. The first cylinder 42 drives a first limiting part 41. The second cylinder 52 is separate from the first cylinder 42 and drives a second limiting part 51.

[0146] Therefore, the first limiting unit 41 and the second limiting unit 51 can be switched by simple control.

[0147] In the supply device 1 of this embodiment, the control unit 70 controls the first restriction unit 41 based on information (storage status, the same below) related to the number of tubes 5 between the first individualization unit 43 and the first transfer unit 47. The control unit 70 controls the second restriction unit 51 based on information related to the number of tubes 5 between the second individualization unit 53 and the second transfer unit 57.

[0148] Therefore, the supply of the cylinder 5 to each side can be switched based on the condition of the first side and the condition of the second side.

[0149] In the supply device 1 of this embodiment, on the horizontal plane, when the direction orthogonal to the transport direction of the transport section 12 is set as the width direction, the upstream transport section 30 has a rear upstream guide section 34, which restricts the position of the tube assembly in the width direction and expands in the width direction as it approaches the downstream.

[0150] This allows for the storage of a larger amount of tube 5, or ensures a width sufficient to connect with the first downstream transport section 40 and the second downstream transport section 50.

[0151] In the supply device 1 of this embodiment, the first downstream conveying unit 40 and the second downstream conveying unit 50 are arranged adjacent to each other. The first separation unit 43 and the second separation unit 53 each have a support platform 65, a drive unit (a first motor 63 or a second motor 64, hereinafter the same) and a separation member 67. The support platform 65 supports the tube 5. The drive unit generates power to move the support platform 65 in the vertical direction. The separation member 67 is arranged along the range of the support platform 65 moving from the lower to the upper direction to separate the tube 5 so that the tube 5 supported on the support platform 65 becomes one.

[0152] Therefore, since the first downstream conveying section 40 and the second downstream conveying section 50 are adjacent, the width dimension of the supply device 1 can be suppressed. In addition, since both the first individualization section 43 and the second individualization section 53 are structures that move in the vertical direction, the width dimension of the supply device 1 can also be suppressed in this respect.

[0153] In the supply device 1 of this embodiment, the control unit 70 controls the conveying speed of the first individualization unit 43 to the bobbin 5 based on information related to the number of bobbins 5 between the first individualization unit 43 and the first transfer unit 47. The conveying speed of the second individualization unit (53) to the bobbin (5) is controlled based on information related to the number of bobbins (5) between the second individualization unit (53) and the second transfer unit (57).

[0154] Therefore, the conveying speed of the tubes 5 of the first individualization section 43 and the second individualization section 53 can be adjusted based on the conditions of the first side and the second side. As a result, for example, when there is sufficient storage of tubes 5, it is possible to slow down the conveying speed of the individualization section 13 and stabilize the operation of the individualization section 13.

[0155] The preparation apparatus 100 of this embodiment includes a supply device 1 and a delivery device 2. The delivery device 2 receives the bobbin 5 supplied by the supply device 1 and delivers the received bobbin 5 to a winding unit 111 to form a package by winding the yarn of the bobbin 5. The path length from the first separation section 43 to the first junction section 47 is longer than the path length from the second separation section 53 to the second junction section 57. The delivery device 2 has a first receiving path 101 and a second receiving path 102. The first receiving path 101 is the path for receiving the bobbin 5 from the first junction section 47. The second receiving path 102 is the path for receiving the bobbin 5 from the second junction section 57 at the second junction position. The delivery device 2 has a branching point from the upstream path into the first receiving path 101 and the second receiving path 102. The length of the first path from the branching point to the first junction position is shorter than the length of the second path from the branching point to the second junction position.

[0156] Therefore, on the first side of the priority transfer tube 5, the path length of the supply device 1 can be increased. Thus, the storage on the supply device 1 side can be increased in the priority path.

[0157] The preparation apparatus 100 of this embodiment includes a supply device 1 and a delivery device 2. The delivery device 2 receives the bobbin 5 supplied by the supply device 1 and delivers the received bobbin 5 to a winding unit 111 formed by winding the bobbin 5 into a package. The delivery device 2 has a first receiving path 101 and a second receiving path 102. The first receiving path 101 is the path for receiving the bobbin 5 from the first junction 47. The second receiving path 102 is the path for receiving the bobbin 5 from the second junction 57 at the second junction position. The delivery device 2 has a branching point from the upstream path into the first receiving path 101 and the second receiving path 102. The length of the first path from the branching point to the first junction position is shorter than the length of the second path from the branching point to the second junction position. The operating speed of the first limiting part 41 is faster than the operating speed of the second limiting part 51.

[0158] Therefore, on the second side where the bobbin 5 is not preferentially handed over, the operating speed of the second limiting part 51 can be made relatively slow. As a result, when the second limiting part 51 is stopped, it is not easy to convey excess bobbin 5 downstream.

[0159] The preferred embodiments of the present invention have been described above, but the above structure can be modified as follows. Modifications can be made individually or in arbitrary combinations.

[0160] In this embodiment, an upstream transport section 30 branches into a first downstream transport section 40 and a second downstream transport section 50. Alternatively, an upstream transport section 30 may branch into three or more transport sections.

[0161] In this embodiment, the device on the first side is used preferentially over the device on the second side. Alternatively, the device on the first side and the device on the second side may have the same priority.

[0162] In the above embodiments, components used to achieve incidental effects can be appropriately omitted. For example, the upstream transport section 30 of this embodiment has a front upstream transport section 31, a rear upstream transport section 33, and an upstream restriction section 35, but the upstream restriction section 35 can also be omitted. In this case, the distinction between the front upstream transport section 31 and the upstream restriction section 35 also disappears, so the upstream transport section 30 is configured as a single inclined surface.
