There are multiple layers, extending along the above-mentioned arrangement direction, so that the above-mentioned empty paper tubes supplemented by the above-mentioned multiple stockers can move along the above-mentioned arrangement direction, and the above-mentioned paper tube moving path has: a supporting surface, extending along the above-mentioned arrangement direction, from The lower side supports the above-mentioned empty paper tubes; the replenishment port is provided at the end of the above-mentioned arrangement direction of the above-mentioned paper tube moving path, and is used to replenish the above-mentioned empty paper tubes; and a plurality of guide parts are used to move the above-mentioned The empty paper tubes are respectively guided to the plurality of stockers.

According to the present invention, the empty paper tubes replenished from the replenishment port to the paper tube moving path move along the arrangement direction in the paper tube moving path. Then, the empty paper tubes moved in the alignment direction are conveyed to the respective stockers via a plurality of guides. Therefore, there is no need for a worker to replenish the empty paper tube by moving to each stocker. Thereby, empty paper tubes can be efficiently replenished to each stocker of the plurality of winding units provided in the false twisting machine.

The paper tube replenishing device of the present invention is preferably further equipped with a plurality of first stoppers arranged at positions corresponding to the guides of the above-mentioned paper tube moving path. The paper tube moving path is switched between a state in which movement of the paper tube moving path to the stocker via the guide is allowed, and a state in which the empty paper tube is restricted from moving from the paper tube moving path to the stocker through the guiding portion.

In the present invention, the first stopper corresponding to the guide portion that guides the empty paper tube to the stocker that is the object of replenishment of the empty paper tube can be set to the allowable state, and can be used for the stocker that is not the object of replenishment of the empty paper tube. The first stop part corresponding to the guide part of the stocker guiding the empty paper tube is set in a restricted state. Thereby, the empty paper tube can be replenished selectively to the stocker which wants to replenish an empty paper tube among a some stocker.

The paper tube replenishing device of the present invention is preferably further equipped with a plurality of second stoppers arranged at positions corresponding to the respective guides on the paper tube moving path, and the second stoppers can allow the empty paper tubes to move Switching between a state in which the paper tube moving path allows movement along the alignment direction and a guiding state in which the empty paper tube is guided to the stocker via the guiding portion, the guiding state is in the second stopper portion , restricting the above-mentioned empty paper tubes from moving beyond the above-mentioned second stop portion along the above-mentioned arrangement direction.

According to the present invention, by setting the second stopper corresponding to the guide portion that guides the empty paper tubes to the stocker as the empty paper tube replenishment target to the guiding state, it is possible to restrict the empty paper tubes from exceeding The 2nd gear stop moves. Therefore, it is possible to suppress movement of the empty paper tube to a position corresponding to a stocker not to be replenished in the paper tube moving path. In addition, the empty paper tube can be properly guided to the stocker to be replenished by the second stopper in the guiding state. Thereby, the empty paper tube can be replenished suitably to the target stocker.

The paper tube replenishing device of the present invention is preferably further provided with a plurality of spacers for adjusting the distance between the adjacent empty paper cores in the above-mentioned arrangement direction and the distance between the adjacent guide parts in the above-mentioned arrangement direction in the above-mentioned paper core moving path. same.

FIG. 2 is a view viewed from the II direction of FIG. 1 . Hereinafter, the direction perpendicular to the plane of paper in FIG. 1 is referred to as the body longitudinal direction, and the left-right direction on the paper is referred to as the body width direction. Let the direction perpendicular to both the body length direction and the body width direction be the up-down direction (vertical direction) in which gravity acts. Hereinafter, description will be given using the above-mentioned directional terms as appropriate.

The false twist processing machine 1 is configured to be able to perform false twist processing on a yarn Y formed of synthetic fibers such as nylon (polyamide fiber), for example. The false twist processing machine 1 includes a yarn supply section 2 for supplying a yarn Y, a processing section 3 for performing false twist processing on the yarn Y supplied from the yarn supply section 2, and winding the yarn Y processed by the processing section 3 into an empty bobbin. The tube (the empty paper tube of the present invention) forms the winding unit 4 for winding the bobbin Bw, and the control unit 40 (see FIG. 5 ). The constituent elements (described later) of the yarn supply unit 2, the processing unit 3, and the take-up unit 4 are arranged on the running surface of the yarn on which the yarn path from the yarn supply unit 2 passes through the processing unit 3 to the take-up unit 4 is arranged. (the paper surface of FIG. 1 ) a plurality of them are arranged in the orthogonal body length direction.

The yarn supply unit 2 has a creel 7 holding a plurality of yarn supply packages Ps, and supplies a plurality of yarns Y to the processing unit 3 . The processing section 3 is configured such that a first yarn supply roller 11, a twist preventing yarn guide 12, a first heating device 13, a cooling device 14, a false twisting device 15, and a second yarn supplying roller are sequentially arranged from the upstream side in the yarn traveling direction.

Moreover, the false twist processing machine 1 has the main body 8 and the winding table 9 arrange|positioned at intervals in the machine width direction. The main body 8 and the take-up table 9 are extended in the length direction of the body to approximately the same length, and are arranged to face each other. The upper part of the main body 8 and the upper part of the winding table 9 are connected by the support frame 10. Each device constituting the processing unit 3 is mainly attached to the main body 8 and the support frame 10 . The main body 8 , the winding table 9 , and the support frame 10 form a working space 22 for an operator to perform operations such as threading on each device. The wire passage is formed so that the wire Y runs mainly around the working space 22 .

The false twist processing machine 1 has a unit unit called a span including a set of a main body 8 and a winding table 9 arranged to face each other. In one span, each device is arranged so that false twisting can be performed simultaneously on a plurality of yarns Y running in a state aligned along the longitudinal direction of the machine body. As an example, a total of 12 winding devices 21 in three layers and four rows are installed on the winding table 9 included in one span (see FIG. 2 ). Furthermore, there is a support frame 10 between two adjacent spans. In this embodiment, the distance between two adjacent winding devices 21 in the body length direction in one span, and the two adjacent spans in the body length direction via the support frame 10 The intervals between the winding devices 21 are the same. In addition, the false twist processing machine 1 is configured such that the span is symmetrically arranged on the paper with the center line C in the width direction of the body of the main body 8 as the axis of symmetry (the main body 8 is common in the left and right spans), and in the length direction of the body There are several listed above.

(Structure of processing department) Next, each constituent element of the processing part 3 is demonstrated. The first yarn supply roller 11 is used to transport the yarn Y supplied from the yarn supply unit 2 to the first heating device 13 .

The second yarn supply roller 16 is arranged on the downstream side of the false twisting device 15 in the yarn traveling direction in the main body 8 . The feeding speed of the yarn Y by the second yarn supply roller 16 is faster than the feeding speed of the yarn Y by the first yarn supply roller 11 . Therefore, the yarn Y is stretched between the first yarn supply roller 11 and the second yarn supply roller 16 .

The entanglement device 17 is a device for applying entanglement by spraying air to the yarn Y. The interlacing device 17 is disposed below the second yarn supply roll 16 in the main body 8 .

The third yarn supply roll 18 is a roll that feeds the yarn Y entangled by the entanglement device 17 toward the second heating device 19 . The third yarn supply roll 18 is disposed below the interlacing device 17 in the main body 8 . The feeding speed of the yarn Y by the third yarn supply roller 18 is slower than the feeding speed of the yarn Y by the second yarn supply roller 16 . Therefore, the yarn Y is loosened between the second yarn supply roller 16 and the third yarn supply roller 18 .

The second heating device 19 is a device for heating the yarn Y fed from the third yarn supply roller 18 . The second heating device 19 is arranged below the third yarn supply roller 18 in the main body 8 . The second heating devices 19 extend in the vertical direction, and are provided one at a time in each span.

The fourth yarn supply roller 20 is a roller that conveys the yarn Y heat-treated by the second heating device 19 toward the winding device 21 . The fourth yarn supply roll 20 is disposed below the winding table 9 . The feeding speed of the yarn Y by the fourth yarn supply roller 20 is slower than the feeding speed of the yarn Y by the third yarn supply roller 18 . Therefore, the yarn Y is loosened between the third yarn supply roller 18 and the fourth yarn supply roller 20 .

In the processing section 3 configured as above, the yarn Y stretched between the first yarn supply roller 11 and the second yarn supply roller 16 is twisted by the false twisting device 15 . The twist formed by the false twist device 15 propagates to the anti-twist guide 12, but does not propagate upstream of the anti-twist guide 12 in the yarn traveling direction. The yarn Y twisted while stretched is cooled by the cooling device 14 after being heated by the first heating device 13 to heat-set. The yarn Y is untwisted downstream of the false twisting device 15, but the state in which each filament is false twisted into a wave shape is maintained by the heat setting described above. The yarn Y subjected to false twisting by the false twisting device 15 is entangled by the entangling device 17 while relaxing between the second yarn supply roller 16 and the third yarn supply roller 18, and is entangled toward the downstream side of the yarn traveling direction. guide. Furthermore, the yarn Y is heat-set by the second heating device 19 while being relaxed between the third yarn supply roller 18 and the fourth yarn supply roller 20 . Finally, the yarn Y fed from the fourth yarn supply roller 20 is wound up by the winding device 21 to form a winding package Pw.

Next, the restriction of the restriction member provided in the stocker 23 is released, and the empty bobbin Bw stored in the stocker 23 is supported by the cradle 31 . Then, the cradle 31 rotates around the rotation shaft 31 a to return to the winding position where the winding device 21 winds the yarn Y, and is again regulated by the regulating member of the stocker 23 . In this way, the empty bobbin Bw stored in the stocker 23 is supplied to the winding device 21 .

In addition, the cradle 31 may be configured so as to be non-rotatably fixed. In this case, the stocker 23 is rotatable around a rotation axis extending along the body longitudinal direction. Then, the empty bobbin Bw stored in the stocker 23 is supplied to the winding device 21 by the rotation of the stocker 23 relative to the fixed cradle 31 .

The storage unit 24 stores the fully wound winding package Pw formed by the winding device 21 . When the winding package Pw becomes fully wound, the cradle 31 rotates about the rotation axis in the longitudinal direction of the body, thereby unloading the winding bobbin Bw supported by the cradle 31 from the winding device 21 and supplying it to the stocker.

When viewed from the up and down direction, the second stopper 53 penetrates the inside of the paper tube moving path 51 from the opening end of the guide 62 and the opening end on the side opposite to the refill port 61 in the longitudinal direction of the body. The way extends along the width direction of the body.

The second stopper 53 can be in the allowable state (the part shown by the dotted line in FIG. 4 ) that allows the empty bobbin Bw to move along the longitudinal direction of the machine body inside the paper tube moving path 51, and can move the empty bobbin Bw through the guide part. 62 to the stocker 23 is switched between the guide state (the part indicated by the solid line and the oblique line in FIG. 4 ). And, when the second stopper 53 is in the guiding state, the empty bobbin Bw is restricted from moving beyond the second stopper 53 along the machine body longitudinal direction. The second stopper 53 is driven by an unillustrated motor, thereby being able to switch between the permitted state and the guided state. The drive of the second stopper 53 is controlled by the control unit 40 . In addition, the driving source of the second stopper 53 is not limited to a motor. For example, the second stopper 53 may be driven by air (air pressure).

The second stopper 53 can move between the inside of the paper tube moving path 51 and the outside of the paper tube moving path 51 via a not-shown slit formed in the paper tube moving path 51 . The second stop portion 53 in the allowable state is located outside the paper tube moving path 51 and opens the inside of the paper tube moving path 51 along the length direction of the machine body. In addition, the second stop portion 53 in the guiding state is located inside the paper tube moving path 51, closes the inside of the paper tube moving path 51 along the longitudinal direction of the machine body, and is formed to guide the empty bobbin Bw to the storage via the guide portion 62. The path guided by the feeder 23. In this way, the second stopper 53 can be switched between the permitted state and the guided state by moving in the vertical direction, and the second stopper 53 in the permitted state is located above the second stopper 53 in the guided state. s position. In addition, the second stopper portion 53 in the permitted state may be positioned below the second stopper portion 53 in the guided state. In addition, the second stopper 53 can also be switched between the permitted state and the guided state by moving in the body width direction.

The spacer 54 is a member that makes the space between the adjacent empty bobbins Bw in the machine length direction on the paper tube moving path 51 equal to the space between the adjacent guide parts 62 in the machine length direction. In the present embodiment, the plurality of spacers 54 and the second stopper portion 53 in the guided state are configured so as not to interfere with each other. For example, a notch is formed below the second stopper portion 53 . In addition, each spacer 54 is arranged so as to be located in a portion where the notch is formed in the second stopper portion 53 in the guided state. Here, "make the space between the adjacent empty bobbins Bw in the body length direction the same as the space between the adjacent guide parts 62 in the body length direction" means that the position of the center of gravity of one empty bobbin Bw in the body length direction is the same as that of the adjacent guide parts 62. The distance between the center of gravity positions of the empty bobbin Bw is the same as the distance between the center of gravity position of one guide portion 62 in the body length direction and the position of the center of gravity of the adjacent guide portion 62 in the body longitudinal direction.

The plurality of spacers 54 are attached to the belt 55 at equal intervals, and the belt 55 can move along the machine body longitudinal direction on the paper tube moving path 51 and can be looped. The belt 55 is an endless belt, and as shown in FIG. 4 , travels in the machine body longitudinal direction on the inside and outside of the paper tube moving path 51 in the machine width direction. In this embodiment, the belt 55 does not have power. The plurality of spacers 54 are movable integrally with the belt 55 along the body length direction. In addition, the belt 55 and the second stopper 53 in the guided state are configured so as not to interfere with each other. For example, the belt 55 is arranged so as to be located in the portion where the notch is formed in the second stopper portion 53 in the guided state. In addition, the belt 55 may run along the longitudinal direction of the machine body on the inside and outside of the paper tube moving path 51 in the vertical direction.

Hereinafter, a series of operations when the empty bobbin Bw is replenished to the stocker 23 by the paper tube replenishing device 50 in this embodiment will be described. First, the operator visually determines which stocker 23 is to be replenished with the empty bobbin Bw. For example, as shown in FIG. 4, among the plurality of stockers 23, the third stocker 23 (hereinafter referred to simply as the third stocker 23) is counted from the side where the supplementary port 61 is provided in the longitudinal direction of the machine body. 23) When there are two stored empty bobbins Bw, the stocker 23 becomes a replenishment target for the empty bobbins Bw. The number of empty bobbins Bw stored in the stocker 23 can be freely determined by the operator as to how many empty bobbins Bw are stored in the stocker 23 . The operator inputs information on the stocker 23 to be replenished with the empty bobbin Bw to an operation terminal (not shown). Information input to the work terminal is sent to the control unit 40 .

Next, the control unit 40 controls the state switching of the first stopper 52 and the second stopper 53 based on the signal. For example, when the third stocker 23 is the replenishment target of the empty bobbin Bw, the control unit 40 controls the switching so that the first stopper 52 corresponding to the third stocker 23 is permitted. state, and the other first stopper portion 52 is in a restricted state. Moreover, the control part 40 controls switching so that the 2nd stopper part 53 corresponding to the 3rd stocker 23 will be in a guide state, and the other 2nd stopper part 53 will be in a permission state. In addition, the state switching of the first stopper 52 and the second stopper 53 by the control unit 40 may be performed based on an electric signal input by the operator by pressing a button provided near the replenishment port 61 .

Next, the operator replenishes the empty bobbin Bw from the replenishment port 61 to the paper tube moving path 51 . At this time, the empty bobbin Bw is arranged between adjacent spacers 54 . A plurality of empty bobbins Bw are sequentially replenished to the paper tube moving path 51 . The empty bobbin Bw inside the paper tube moving path 51 is pushed by the empty bobbin Bw newly replenished to the paper tube moving path 51 from the replenishment port 61 through the spacer 54, thereby moving along the machine body longitudinal direction. At this time, the empty bobbin Bw moves along the body longitudinal direction together with the spacer 54 and the belt 55 .

Then, when the empty bobbin Bw moving along the machine body longitudinal direction in the paper tube moving path 51 reaches the position corresponding to the third stocker 23 as the replenishment object, it passes through the second stopper 53 in the guiding state. , replenished into the stocker 23 via the guide portion 62 corresponding to the first stopper portion 52 in the permitted state. When the number of empty bobbin tubes Bw stored in the third stocker 23 reaches the maximum number of four, the control unit 40 controls the switching so that the first stopper corresponding to the third stocker 23 52 is in a restricted state, and the second stopper 53 corresponding to the third stocker 23 is in a permitted state. Thereafter, the replenishment of the empty bobbin Bw is stopped until the stocker 23 to be replenished with the empty bobbin Bw is generated. When the stocker 23 to be replenished with the empty bobbin Bw is generated, the above-described series of operations are performed.

(Effect) The paper tube replenishing device 50 of the present embodiment has a paper tube moving path 51, and the paper tube moving path 51 is provided with multiple layers corresponding to the multi-layer winding unit 30, extending along the length direction of the machine body, so that a plurality of stockers 23 The supplementary empty bobbin Bw can be moved along the length of the body. And, paper tube moving path 51 has: supporting surface 51a, extends along the body length direction, and supports empty bobbin Bw from below; Replenishment port 61, is arranged on the end portion of the body length direction of paper tube moving path 51, is used for replenishing. an empty bobbin Bw; and a plurality of guide parts 62 for guiding the empty bobbin Bw moving along the body longitudinal direction to the plurality of stockers 23, respectively. According to the above configuration, the empty bobbin Bw replenished from the replenishment port 61 to the paper tube moving path 51 moves along the body longitudinal direction in the paper tube moving path 51 . Then, the empty bobbin Bw moved along the machine body longitudinal direction is conveyed to each stocker 23 via a plurality of guide parts 62 . Therefore, there is no need for a worker to move to each stocker 23 to replenish the empty bobbin Bw. Accordingly, the empty bobbin Bw can be efficiently replenished to each stocker 23 of the plurality of winding units 30 provided in the false twisting machine 1 .

The paper tube replenishing device 50 of the present embodiment has a plurality of first stoppers 52 provided at positions corresponding to the respective guides 62 of the paper tube moving path 51 . The first stopper part 52 can be in the allowable state of allowing the empty bobbin Bw to move from the paper tube moving path 51 to the stocker 23 via the guide part 62, and restrict the empty bobbin Bw from the paper tube moving path 51 to the stocker 23 through the guide part 62. The stocker 23 is switched between restricted states of movement. In the above configuration, the first stopper portion 52 corresponding to the guide portion 62 that guides the empty bobbin Bw to the stocker 23 that is the replenishment target of the empty bobbin Bw can be set to the allowable state, and the non-empty bobbin can be set to the non-empty bobbin. The 1st stopper part 52 corresponding to the guide part 62 which guides the empty bobbin tube of the stocker 23 which is the replenishment object of the tube Bw is made into a restrained state. Thereby, an empty bobbin can be selectively replenished to the stocker 23 to replenish the empty bobbin Bw among the plurality of stockers 23 .

The paper tube replenishing device 50 of the present embodiment has a plurality of second stoppers 53 provided at positions corresponding to the respective guides 62 of the paper tube moving path 51 . The second stopper 53 can be set between a permitted state in which the empty bobbin Bw is allowed to move along the longitudinal direction of the machine body in the paper tube moving path 51 , and a guiding state in which the empty bobbin Bw is guided to the stocker 23 via the guide portion 62 . switch between. And, when the second stopper 53 is in the guiding state, the empty bobbin Bw is restricted from moving beyond the second stopper 53 along the machine body longitudinal direction. According to the above configuration, by setting the second stopper 53 corresponding to the guide portion 62 for guiding the empty bobbin Bw to the stocker 23 to be replenished with the empty bobbin Bw in the guiding state, the empty bobbin can be restricted. Bw moves beyond the second stopper portion 53 along the body length direction. Therefore, it is possible to suppress movement of the empty bobbin Bw to a position corresponding to the stocker 23 not to be replenished in the paper tube moving path 51 . In addition, the empty bobbin Bw can be appropriately guided to the stocker 23 to be replenished by the second stopper portion 53 in the guiding state. Accordingly, the empty bobbin Bw can be appropriately replenished to the target stocker 23 .

The paper tube replenishing device 50 of the present embodiment has a plurality of spacers 54 that make the distance between the adjacent empty bobbins Bw in the body length direction of the paper tube moving path 51 and the distance between the adjacent guide parts 62 in the body length direction the same interval. In this embodiment, the other end (end opposite to the side where the replenishment port 61 is provided) in the body longitudinal direction of the paper tube moving path 51 is closed. Alternatively, the second stopper portion 53 in the guiding state blocks any position in the machine body longitudinal direction of the paper tube moving path 51 . In this case, among the plurality of empty bobbins Bw moving in the paper tube moving path 51, the empty bobbins Bw not replenished to the stocker 23 are transported to one side end of the paper tube moving path 51 or The position of the second stopper portion 53 in the guiding state stays in the paper tube moving path 51 . Then, when a plurality of empty bobbins Bw are staying in the paper tube moving path 51 and the empty bobbin Bw is further replenished to a certain stocker 23, the empty bobbins staying in the paper tube moving path 51 One of the tubes Bw is replenished in the stocker 23 . Here, when a plurality of empty bobbins Bw are simultaneously moved in the paper tube moving path 51, the intervals in the arrangement direction of the adjacent empty bobbins Bw may be narrowed. Then, the empty bobbin Bw staying in the paper tube moving path 51 may exist at a position where it cannot be properly guided to the stocker 23 via the guide part 62 . According to the present embodiment, the distance between adjacent empty bobbins Bw and the distance between adjacent guide portions 62 can be made equal by the spacer 54 . Accordingly, it is possible to prevent the empty bobbins Bw staying in the paper tube moving path 51 from existing at positions where they cannot be properly guided to the stocker 23 via the guide portion 62, and it is possible to replenish the empty bobbins to the stocker 23 more reliably. Bw.

In addition, the paper tube replenishing device 50 of this embodiment has a belt 55 on which a plurality of spacers 54 are attached, and the belt 55 can move along the body length direction in the paper tube moving path 51 and can be looped. When only the spacer 54 is provided, the spacer 54 stays in the paper tube moving path 51 after the empty bobbin Bw moved in the paper tube moving path 51 is replenished to the stocker 23 . The operator needs to collect the spacer 54 remaining in the paper tube moving path 51, which is troublesome for the operator. According to the said structure, the several spacer 54 is attached to the belt 55 which can move along the machine body longitudinal direction in the paper tube moving path 51, and can loop. Therefore, it is not necessary for the operator to collect the spacer 54 remaining in the paper tube moving path 51, and it is possible to reduce the trouble of the operator.

In the paper tube replenishing device 50 of the present embodiment, the replenishment port 61 is provided only at one end portion of the paper tube moving path 51 in the body longitudinal direction. According to the above-mentioned structure, it is only necessary to replenish the empty bobbin Bw from the replenishment port 61 provided only at one end of the paper tube moving path 51. It is easier to replenish the empty bobbins Bw to the paper tube moving path 51 than when replenishing the empty bobbins Bw separately.

In the paper tube replenishing device 50 of the present embodiment, the empty bobbin Bw of the paper tube moving path is pushed by the empty bobbin Bw newly replenished to the paper tube moving path 51 from the replenishing port 61, thereby moving along the machine body longitudinal direction. . According to the above configuration, the empty bobbin Bw supplied to the paper tube moving path 51 by the operator pushes the adjacent empty bobbin Bw, thereby moving the empty bobbin Bw along the machine body longitudinal direction. Therefore, the empty bobbin Bw can be moved along the body longitudinal direction without providing a device for moving the empty bobbin Bw of the paper tube moving path 51 along the body longitudinal direction. This eliminates the need for a complicated configuration for the entire device, and enables cost reduction of the device.

In addition, in the paper tube replenishing device 50 of this embodiment, the paper tube moving path 51 has a cylindrical shape extending along the machine body longitudinal direction. According to the above configuration, it is possible to reliably prevent the empty bobbin Bw moving in the paper tube moving path 51 from falling out from the paper tube moving path 51 , and it is possible to reliably replenish the empty bobbin Bw to each stocker 23 .

(Modification) Modifications to the above-described embodiment will be described below. However, the same reference numerals are attached to the parts having the same configuration as those in the above-mentioned embodiment, and the description thereof will be appropriately omitted.

In the present invention, as shown in FIG. 6, the paper tube replenishing device 150 may also have an empty paper tube automatic feeding device 70, which can automatically drop the empty bobbin Bw from the replenishing port 61 to the paper tube. The tube moves to Road 51. For example, the empty paper tube automatic feeding device 70 has a paper tube box 71 , a paper tube path 72 and an automatic feeding device 73 . The cardboard box 71 can store a large number of empty bobbins Bw. The paper tube path 72 is connected to three replenishment ports 61 of the paper tube moving path 51 provided in three stages. The automatic feeding device 73 automatically drops the empty bobbin Bw in the paper tube path 72 into the paper tube moving path 51 through the replenishment port 61 . The automatic dispensing device 73 is constituted by, for example, an air cylinder or the like. The empty bobbins Bw stored in the paper tube box 71 are conveyed downward through the paper tube path 72 . At this time, the axial direction of each empty bobbin Bw is aligned so that it may correspond to the longitudinal direction of a machine body. Of the empty bobbins Bw conveyed downward through the paper tube path 72 , the empty bobbin Bw at a position corresponding to the replenishment port 61 is automatically dropped into the paper tube moving path 51 by the automatic feeding device 73 . The connecting portion between the paper tube path 72 and the refill port 61 is tapered, and the empty bobbin Bw pushed by the automatic feeding device 73 as an air cylinder is guided to the refill port 61 along the tapered surface. According to this configuration, compared with the case where the operator manually inserts the empty bobbin Bw into the paper tube moving path 51, the trouble of the operator can be reduced, and the working time can be shortened. In addition, the paper tube replenishing device 150 has a positioning plate provided inside the paper tube path 72 to position the empty bobbin Bw at a height at which it can be replenished to the replenishing port 61 . The positioning plate is movable between a positioning position where the empty bobbin Bw is positioned, and a retreat position where it does not interfere with the downward movement of the empty bobbin Bw. The empty bobbin Bw positioned by the positioning plate at the positioning position is pushed by the automatic feeding device 73 as an air cylinder, thereby replenishing the paper tube moving path 51 through the replenishing port 61 .

In addition, the empty paper tube automatic feeding device is not limited to the example shown in FIG. 6 , for example, the empty bobbin Bw may be automatically fed into the paper tube moving path 51 from the replenishment port 61 by a robot arm or the like.

In the above-described embodiment, the empty bobbin Bw of the paper tube moving path 51 is pushed by the empty bobbin Bw newly replenished into the paper tube moving path 51 from the replenishment port 61, thereby moving along the machine body longitudinal direction. However, the paper tube moving path 51 may have a conveying device for conveying the empty bobbin Bw along the body longitudinal direction. As the transport device, for example, a conveyor provided on the bottom surface of the paper tube moving path 51 can be mentioned. The empty bobbin Bw placed on the conveyor is conveyed along the body length direction by the drive of the conveyor. In addition, the conveying device may press the empty bobbin Bw along the body length direction by air from the end of the paper tube moving path 51 on the side where the replenishment port 61 is provided. Furthermore, the conveying device may suck the empty bobbin Bw along the body longitudinal direction by air from the end of the paper tube moving path 51 on the side opposite to the side where the replenishment port 61 is provided. According to these configurations, the empty bobbin Bw in the paper tube moving path 51 can be transported by the transport device along the body longitudinal direction. Therefore, it is not necessary for the operator to press-in the empty bobbin Bw manually, and it is possible to reduce the trouble of the operator.

In addition, when the paper tube moving path 51 has a conveyor as a conveyor for conveying the empty bobbin Bw along the body longitudinal direction, a plurality of spacers 54 may be attached to the conveyor. In this case, the conveyor corresponds to the belt of the present invention.

In the above embodiment, the paper tube moving path 51 has a cylindrical shape extending along the machine body longitudinal direction. However, the paper tube moving path 51 may be configured such that the upper side is open and the cross-sectional shape perpendicular to the longitudinal direction of the machine body is semicircular. In addition, the paper tube moving path 51 may be a flat plate-shaped member, or may have a configuration in which side walls are provided on both sides of the flat plate-shaped member in the body width direction.

In the above-described embodiment, the stocker 23 to be replenished with the empty bobbin Bw is determined by the operator's visual inspection. However, the stocker 23 to be replenished with the empty bobbin Bw may also be determined by a sensor provided in the stocker 23 . For example, when it is recognized by the sensor that the number of empty bobbins Bw stored in the stocker 23 has decreased, the stocker 23 is determined to be a replenishment target for the empty bobbins Bw. In this case, a signal including information on the stocker 23 to be replenished with the empty bobbin Bw is sent from the sensor to the control unit 40 . Then, the control unit 40 automatically controls the state switching of the first stopper part 52 and the second stopper part 53 based on the signal. In addition, the state switching of the first stopper 52 and the second stopper 53 by the control unit 40 may be performed based on an electric signal input by the operator by pressing a button provided near the replenishment port 61 .

In the above-described embodiment, the paper tube moving path 51 is connected to each stocker 23 at a position where each guide portion 62 is formed. However, the paper tube moving path 51 and each stocker 23 may not be connected, and a gap may exist between the paper tube moving path 51 and the stockers 23 . In this case, the guide portion 62 includes an opening formed in the paper tube moving path 51 and a passage connecting the paper tube moving path 51 and the stocker 23 .

In the above embodiment, the paper tube replenishing device 50 has the belt 55 to which the plurality of spacers 54 are attached. However, the paper tube replenishing device 50 may not have the belt 55 . In this case, the independent spacers 54 are arranged between the adjacent empty bobbins Bw in the paper tube moving path 51 . In this case, the operator appropriately recovers the spacer 54 remaining in the paper tube moving path 51 . In addition, the paper tube replenishing device 50 may not have the spacer 54 . In this case, it is preferable to install a conveyor on the bottom surface of the paper tube moving path 51 . By adjusting the position of the empty bobbins Bw arranged on the conveyor, the distance in the longitudinal direction of the body of the adjacent empty bobbins Bw in the paper tube moving path 51 can be made the same as the distance in the longitudinal direction of the body of the adjacent guide parts 62 .

In the above embodiment, the paper tube replenishing device 50 has the plurality of first stoppers 52 and the plurality of second stoppers 53 . However, the paper tube replenishing device 50 may have only one of the first stopper 52 and the second stopper 53 . In the case where only the first stopper 52 and the first stopper 52 of the second stopper 53 are arranged, the empty bobbin Bw replenished from the replenishment port 61 to the paper tube moving path 51 is returned to the permitted state. The stocker 23 corresponding to the lower first stopper portion 52 is replenished, and the stocker 23 corresponding to the first stopper portion 52 in the restricted state is not replenished. In this case, it is preferable to provide a conveyor on the bottom surface of the paper tube moving path 51 . When the empty bobbin Bw moving in the paper tube moving path 51 reaches a position corresponding to the guide part 62 for guiding the empty bobbin Bw to the stocker 23 to be replenished, by stopping the operation of the conveyor, it is possible to The empty bobbin Bw is properly guided to the hopper 23 .

In the case where only the second stopper 53 of the first stopper 52 and the second stopper 53 is arranged, the empty bobbin Bw replenished from the replenishment port 61 to the paper tube moving path 51 is replenished to the same The stocker 23 corresponding to the second stopper portion 53 in the guided state and the stocker 23 located on the side of the replenishment port 61 in the body length direction relative to the stocker 23 . In the case where only the second stopper 53 is configured, the empty bobbin Bw replenished from the replenishment port 61 to the paper tube moving path 51 is not transferred to the stocker corresponding to the second stopper 53 in the guiding state. Device 23 is replenished by the stocker 23 on the side opposite to replenishment port 61 in the length direction of the body. In this case, it is preferable that a pushing mechanism for pushing out the empty bobbin Bw in the paper tube moving path 51 toward the stocker 23 is provided in the paper tube moving path 51 . The empty bobbin Bw that has reached the position where the second stopper portion 53 exists in the guided state is pushed out toward the stocker 23 by the pushing mechanism, thereby replenishing the stocker 23 . In addition, in the configuration having the push-out mechanism, a movement preventing member may be provided in the paper tube moving path 51 to restrict the passage of the empty bobbin Bw in the paper tube moving path 51 through the guide portion 62 opened obliquely downward. And move toward stocker 23 naturally. The empty bobbin Bw pushed out by the pushing mechanism reaches the stocker 23 over the movement preventing member.

In addition, in the case where only the second stopper 53 of the first stopper 52 and the second stopper 53 is arranged, the guide part 62 may also be able to open upward and to face the stocker. Switch between the downward-facing state in which the container 23 opens obliquely downward. In this case, when the empty bobbin Bw moving in the paper tube moving path 51 reaches a position corresponding to the guide part 62 for guiding the empty bobbin Bw to the stocker 23 to be replenished, the guide part 62 faces downward. state. Thereby, the empty bobbin Bw in the paper tube moving path 51 moves to the stocker 23 through the guide part 62 . When the empty bobbin Bw moving in the paper tube moving path 51 is at a position corresponding to the guide part 62 guiding the empty bobbin Bw to the stocker 23 not to be replenished, the guide part 62 is in an upward state. Accordingly, the empty bobbin Bw cannot move toward the stocker 23 through the guide portion 62 . In addition, switching between the upward state and the downward state can be performed, for example, by rotating the paper tube moving path 51 around a rotation axis along the machine body longitudinal direction.

In addition, in the present invention, the paper tube replenishing device 50 may not have any of the first stopper 52 and the second stopper 53 . In this case, when there are a plurality of stockers 23 to be replenished with empty bobbins Bw, the empty bobbins Bw replenished from the replenishment port 61 to the paper tube moving path 51 are located closest to the replenishment port 61. The accumulator 23 replenishes sequentially. In addition, in this case, for the stocker 23 storing the largest number of empty bobbins Bw, the empty bobbin Bw stored in the stocker 23 last prevents new empty bobbins Bw from flowing to the stocker. 23 supplements. For example, with regard to the stocker 23 with a maximum storage quantity of 4 empty bobbins Bw, for the stocker 23 storing 4 empty bobbins Bw, the fourth stocker 23 stored in the stocker 23 The empty bobbins Bw prevent the replenishment of the hopper 23 with new empty bobbins Bw.

In the above embodiment, the paper tube moving path 51 has a cylindrical shape. However, the paper tube moving path 51 is not limited to a cylindrical shape. For example, when viewed from the longitudinal direction of the machine body, the paper tube moving path 51 may be trapezoidal or square. In addition, the paper tube moving path 51 may also be configured to have a supporting surface extending in the longitudinal direction of the body and supporting the empty bobbin Bw from below, and two end portions extending in the longitudinal direction of the body and connecting to the supporting surface in the width direction of the body. In the connected wall portion, the upper side of the paper tube moving path 51 is opened. In this case, the vertical height of the wall portion is preferably longer than the diameter of the empty bobbin Bw. Specifically, the paper tube moving path 51 may also be in the shape of a U-shape, a U-shape, or a "ワ" shape when viewed from the longitudinal direction of the machine body.
