Are connected by a smooth curve.
Here, the automatic winder 2 and the spinning machine 1 serving as the start and end of the transport paths 7a and 7b have the same or different height positions. Moreover, the conveyance surface height which is the height from the floor surface 11 of the conveyance surface of the conveyors 6 and 8 of the automatic winder 2, or the conveyance surface height of the conveyors 5 and 9 of the spinning machine 1 is the horizontal conveyance surface. It is different from the conveying surface height of the bottom section. In addition, the conveyance surface height here means the height which uses the floor surface 11 as a reference plane. Further, the conveyance guide member 3 is also appropriately bent according to the shape of the conveyance paths 7a and 7b.

Further, as shown in FIG. 11, the conveyance guide member 3 is formed by a guide plate 20 partitioned so as to surround the tray T. The guide plate 20 includes a bottom guide plate 20a (FIG. 3) and a side guide plate 20b ( 2) and an upper guide plate 20c (FIG. 3), which is continuously extended in the transport direction A. And this guide plate 20 is formed so that the attitude | position of the tray T may be changed in the bending part 21 which connects the connection part 17 and the inclination area 18 which were shown in FIG.
That is, the guide plate 20 of the bent portion 21 is formed to be bent while being twisted by 90 degrees with respect to the conveyance direction A as an axis, and becomes a connection portion between the spinning machine 1 and the actual bobbin conveyance path 7a. The tray T in which the actual bobbin B1 stands in the connection portion 17 is tilted in the conveyance crossing direction in the inclined section 18 so that the actual bobbin B1 is horizontal. That is, in the actual bobbin conveyance path 7a and the empty bobbin conveyance path 7b, the bobbin B in which the axial direction of the bobbin is upright is lowered from the connection portion 17 while being twisted (underground twist), conveyed in the conveyance direction A, and leveled to the underground conveyance path. 12 is conveyed. Then, when raising from the underground conveyance path 12, the bobbin B whose axis direction of the bobbin is tilted horizontally is returned to an upright posture while gradually twisting.
In this embodiment, the actual bobbin B1 and the empty bobbin B0 of both the conveyance paths 7a and 7b are tilted toward the center so that the tips of the bobbins B0 face each other. In addition, the tilting posture of the tray T is continuously maintained in the horizontal base section 19 and is conveyed while being tilted over the entire detour portion 13.

Shows an example in which they are connected by a smooth curve, but the detouring portion 13 is steeply formed substantially vertically downward from the vicinity of the connecting portion 17 so that the vertical direction of the conveying path is substantially perpendicular to the horizontal direction. You may comprise so that the base-side area 19 can be ensured more widely by forming a section and connecting with the base-side area 19 by the shortest path | route. By doing so, the width of the passage 16 can be secured further.
In this embodiment, the bobbin transport paths 7a and 7b connecting the automatic winder 2 and the spinning machine 1 are provided in the basement. However, the present invention is not particularly limited, and a transport path connecting the automatic winder 2 and the spinning machine 1 is provided. It does not matter as a structure provided above. For example, although not shown, a bypass conveyance path of the bobbin conveyance path is provided so as to be detoured in the vicinity of the ceiling part or in the ceiling part, and the tray T is raised while twisting to tilt the axial direction of the bobbin B from the upright direction to the horizontal direction. In the horizontal conveyance section, the bobbin B may be conveyed while being tilted, and then the axial direction of the tilted bobbin B may be returned from the horizontal direction to the upright direction.

As shown in FIGS. 1 and 2, the feeding means 4 includes the vicinity of the end of the bottom section 19 on the spinning machine 1 side of the actual bobbin transport path 7a and the end of the bottom section 19 on the automatic winder 2 side of the empty bobbin transport path 7b. It is arranged so as to be substantially parallel to the transport direction A in the vicinity of the part.
In the present embodiment, the feeding means 4 is provided in the bottom section 19 of the transport path 7, but may be provided in a location other than the bottom section 19 in the middle of the transport path 7.

Subsequently, the feeding unit 4 will be described with reference to FIGS. 3 and 4.
As will be described in detail later, the feeding means 4 is the same as when the tray T is transported one sheet (hereinafter referred to as one feeding) by one driving of the air cylinder 22 (reciprocating motion in the transport direction A) (FIG. 3). It is configured to be switchable between the case where two trays T are conveyed (hereinafter referred to as two feeding) (FIG. 4). That is, the feeding means 4 can change the transport quantity of the bobbin B in units of one stroke or tray.
The feed means 4 includes an air cylinder 22 that expands and contracts along a transport direction A serving as a drive source, a moving member 24 that is fixed to the piston rod 23 via a bracket and moves (conveys) the tray T by reciprocation. A guide portion 26 that guides the reciprocating motion along the conveying direction A through the moving member 24 so as to be slidable, a stopper 27 that restricts the movement of the moving member 24 at a predetermined position, and supported by the moving member 24. The push lever 25 is engaged with the tray T.
The air cylinder 22 is fixed to the bottom guide plate 20a via a support member 22a.

The push lever 25 is supported by the moving member 24 on the guide portion 26 so as to be rotatable around the vertical axis 25a. The moving member 24 is provided with a spring 28 which is an example of an elastic body that urges the tip of the push lever 25 toward the guide plate 20a. For this reason, the push lever 25 is in a state of facing obliquely toward the conveyance direction A, and the leading end of the push lever 25 is conveyed from the opening 35 formed in the bottom guide plate 20a to the conveyance paths 7a and 7b. It protrudes to the center side.
And the front-end | tip of the push lever 25 enters into the concave chamber 29 currently formed in the bottom part of the tray T for blowing up a yarn end. That is, when the air cylinder 22 is retracted in the transport direction A, the push lever 25 pushes the inner wall 30 of the concave chamber 29 and moves the tray T in the transport direction A. On the other hand, when the air cylinder 22 is extended, the push lever 25 is pressed by the bottom of the tray T and is released from the concave chamber 29 without pushing the tray T in the transport direction A. In addition, it engages with the next tray T connected to the rear of the tray T in the transport direction A (the push lever 25 enters the concave chamber 29).
Further, the air cylinder 22 is formed so as to exert a sufficient pressing force so that by pushing one tray T, the air cylinder 22 can move against the total weight of the trays T that are conveyed in series. .
As described above, when the air cylinder 22 is retracted in the transport direction A, the push lever 25 presses the inner wall 30 of the concave chamber 29, so that the tray T moves in the transport direction A. Instead, the front and rear of the air cylinder 22 are arranged in the opposite direction so that when the air cylinder 22 extends in the transport direction A, the push lever 25 pushes the inner wall 30 of the concave chamber 29. T may be configured to move in the transport direction A.

In addition, as shown in FIGS. 3 and 4, the air cylinder 22 is provided with an origin sensor 31, a position sensor 32, and a position sensor 33 that are position detection means. Further, as shown in FIG. 5, the three-point position detecting means is connected to a controller 34 that is a control means of the bobbin conveying device 10. And it is comprised so that the origin position and predetermined feed position in each expansion-contraction position of the air cylinder 22 can be detected.
The stopper 27 is provided as a movement restraining means. In other words, it is possible to set the movement stop position of the moving member 24 by the stopper 27 in accordance with the setting change of the transport quantity of the tray T in the one stroke unit of the air cylinder 22 (one feed or two feed in this embodiment). Has been. 3 and 4 show the same feeding means 4, FIG. 3 shows the case of single feeding, and FIG. 4 shows the case of two feeding. FIG. 3 shows the case where the transport quantity is set to one feed, but the tray 27 is set so that it can cope with either the single feed or the double feed at the setting position of the stopper 27 on the guide portion 26. The position is restricted when it slides toward the width of T and the conveyance direction A and is not stopped when it slides toward the width of T and the conveyance direction A.
Further, FIG. 4 shows a case where the transport quantity is set to two feeding, and the position of the stopper 27 on the guide portion 26 is the width of two trays T in the transport direction A as in the case of the single feeding. The position is restricted when the moving member 24 slides.
If it is considered that only one feed is used for the time being, the stopper 27 may be arranged at the position of the two-dot chain line in FIG.

Thus, the origin sensor 31 and the position sensor 32 shown in FIG. 3 are installed for detecting the feed position in the conveyance for one tray T. For example, the origin sensor 31 detects the case where the air cylinder 22 is extended to the rear in the conveyance direction A as the origin position. When the air cylinder 22 is degenerated by a width of one tray T in the transport direction A to push the tray T, the position sensor 32 detects that the feeding of one tray T is completed.
In the single feed switching example shown in FIG. 3, the driving of the air cylinder 22 is controlled mainly based on the position detection by the origin sensor 31 and the position sensor 32.

That is, in detail, the origin position of the air cylinder 22 is a position when the air cylinder 22 extends to the rear in the conveyance direction A at the maximum. The origin sensor 31 detects whether the air cylinder 22 is at the origin position.
The single-cylinder feed position of the air cylinder 22 is a position when the air cylinder 22 is degenerated by a width corresponding to one tray T in the transport direction A from the origin position. The position sensor 32 detects whether or not the air cylinder 22 is in the single feed position.
In the case of single feed, when the position sensor 32 detects that the air cylinder 22 has reached the single feed position by retracting the air cylinder 22 at the origin position in the transport direction A and feeding out the tray T, the air cylinder 22 It is controlled by the controller 34 so as to stop the drive of.
Further, when only the single feed described above is used for the time being, the stopper 27 is provided so that the air cylinder 22 does not go too far from the single feed position (position shown by a two-dot chain line in FIG. 3).

Also, the origin sensor 31 and the position sensor 33 shown in FIG. 4 are installed for detecting the feed position in the transport for two trays T. The origin sensor 31 detects the case where the air cylinder 22 extends to the rear in the conveyance direction A as the origin position. When the air cylinder 22 is retracted by the width of two trays T in the transport direction A to push the tray T, the position sensor 33 detects that the two trays T have been fed. .
The feeding means 4 shown in FIG. 4 is a case where the conveyance quantity is set to two feeding, and the position of the stopper 27 on the guide portion 26 is one feeding or two feeding as described above. However, in order to be able to respond, the width is set to two trays T, and the position is restricted only when sliding in the transport direction A. The stopper 27 does not restrict the moving member 24 when the transport quantity is changed to one feed according to the situation, that is, when the width is changed to slide in the transport direction A for the width of one tray T.
In the case of the two-feed switching example shown in FIG. 4, the driving of the air cylinder 22 is controlled based on the position detection by the origin sensor 31 and the position sensor 33.

That is, in detail, the origin position of the air cylinder 22 is a position when the air cylinder 22 extends to the rear in the conveyance direction A at the maximum. The origin sensor 31 detects whether or not the air cylinder 22 is at the origin position.
The two-cylinder feed position of the air cylinder 22 is a position when the air cylinder 22 is degenerated by a width corresponding to two trays T in the transport direction A from the origin position. The position sensor 33 detects whether or not the air cylinder 22 is in the two-feed position.
In the case of two-piece feeding, the air cylinder 22 at the origin position is retracted in the transport direction A and the tray T is sent out. When the position sensor 33 detects that the air cylinder 22 has reached the two-piece feeding position, It is controlled by the controller 34 so as to stop the driving of the cylinder.
Further, the stopper 27 is provided so that the air cylinder 22 does not go beyond the two-feed position.
In this embodiment, an example of the arrangement of sensors up to two feeds is shown as a position sensor. However, the position sensor is not particularly limited, and two pieces are set by appropriately setting the specifications of the air cylinder, the sensor installation position or the number of sensors installed. It is also possible to configure to send a plurality of the above. For example, the position sensor may be arranged so as to detect feed positions corresponding to a plurality of widths that are equal to or larger than the width of three trays T.
Further, as in the present embodiment, not only the position detection means is provided in the feed means 4 to indirectly recognize the feed quantity of the tray T but also the position detection means (for example, an optical sensor) of the tray T is provided on the transport path. It may be configured to provide the position detection directly.
In this embodiment, the push lever 25 is engaged with the inner wall 30 that is the inner portion of the bottom of the tray T to push and convey the tray T. FIG. 6A is a schematic plan view ( b) As shown in the schematic side view, the push lever 41 may be brought into contact with the outer side surface of the bottom of the tray T so as to push the tray T from the outside for conveyance.
Further, the feeding means 4 is not limited to the above configuration, and any configuration can be used as long as it is a known means. Hereinafter, another specific example of the feeding means will be described.

Next, another embodiment of the feeding means will be described with reference to FIGS.
FIG. 7 is a view showing another embodiment of the feeding means in which the pushing lever is arranged on the timing belt. FIG. 7A is a plan view, and FIG. 7B is a drawing showing the pushing lever, the timing belt and the motor portion of the feeding means. FIG. 8A and 8B are diagrams showing another embodiment of the feeding means in which the pushing lever is arranged on the ball screw. FIG. 8A is a plan view, and FIG. 8B shows the pushing lever, the ball screw and the motor portion of the feeding means. It is a side view.
For example, instead of using an air cylinder as a drive source as described above as a drive mechanism of the feeding means, a moving member 43 supporting a push lever 45 is disposed on a timing belt 44 as shown in FIG. The motor 42 may be used as the source, and the timing belt 44 may be reciprocated along the transport direction A by driving the motor 42.
Further, as shown in FIG. 8, a moving member 53 supporting a push lever 55 is arranged on a ball screw 56 by converting a rotary motion provided with a motor 52 as a drive source into a reciprocating motion. A method of reciprocating the moving member 53 along the conveyance direction A by driving may be used.
Although not shown, a moving member that supports a push lever is disposed on the pinion by a method of converting a rotary motion by a rack and pinion mechanism having a motor as a drive source into a reciprocating motion, and the pinion is driven by the motor. May be reciprocated along the conveying direction A.
In another embodiment of the feeding means as described above, a motor is used as a drive source, but it is possible to perform rotation control of the motor by servo control or pulse control. For example, when rotation control is performed by pulse control, that is, when a stepping motor is used, the feeding means can be configured at a lower cost than a servo motor. Further, the rotation control by the pulse control can accurately control the feed position of the tray T as in the example in which the air cylinder 22 used in the present embodiment is provided with the position detection means.
In another embodiment of the feeding means that does not use an air cylinder as the drive source described above, one stroke is defined as driving the motor and causing the push lever to reciprocate once in the transport direction A at a predetermined interval. .

In such a configuration, for example, the tray T of the actual bobbin B1 produced by the spinning machine 1 is fed from the carry-out conveyor 5 to the connecting portion 17 of the actual bobbin conveyance path 7a, and the bottom section 19 via the inclined section 18. Enter. When the air cylinder 22 of the feeding means 4 disposed in this portion is retracted, the push lever 25 pushes the bottom of the tray T, so that the entire tray T in front of the transport direction A has a predetermined stroke length. Move forward by minutes.
Specifically, one air cylinder 22 is moved by the position sensor 32 and the position sensor 33 from the state where the push lever 25 and the moving member 24 of FIG. 3 or 4 are positioned (origin position). The drive is continued until it is detected that the feed position or the double feed position has been moved.
Then, the air cylinder 22 is driven until it is detected by the position sensor 32 or the position sensor 33 that the air cylinder 22 has moved to the single feed position or the double feed position.
Here, when it is possible to change the transport quantity at any time, the stopper 27 is fixed at a position corresponding to two-feed as described above, and the position restriction is made so that the feed position does not shift only in the case of two-feed. Is supposed to do. When the transport quantity is changed to single feed, position restriction is not performed.

Next, a method for controlling the bobbin transport device 10 will be described with reference to FIG.
As described above, the spinning machine 1 has the controller 1a, and the controller 1a recognizes the processing status such as the production status of the actual bobbin B1 of the spinning machine 1 as needed. The automatic winder 2 has a controller 2a, and a bobbin detection sensor 36, a full sensor 37, a bobbin stopper 38, and a supply amount detection sensor 40, which will be described later, are connected to the controller 2a. The controller 2a recognizes the processing status of the automatic winder 2 as needed based on detection signals from the bobbin detection sensor 36, the full sensor 37, and the like.
The bobbin conveying device 10 has a controller 34. The controller 34 is an origin sensor which is a position detection means for detecting that the air cylinder 22 has moved to the origin position, the single feed position, or the double feed position. 31, the position sensor 32, the position sensor 33, and the air cylinder 22 are connected. The expansion / contraction position of the air cylinder 22 is transmitted to the controller 34 by these sensors. Furthermore, the controller 34 can recognize the transport quantity of the bobbin B to the automatic winder 2 or the spinning machine 1 by each sensor.
The controller 1 a of the spinning machine 1 and the controller 2 a of the automatic winder 2 are connected to the controller 34 of the bobbin transport device 10.
In this way, the processing status in the automatic winder 2 is transmitted from the controller 2a of the automatic winder 2 to the controller 34 of the bobbin transport device 10. The processing status of the spinning machine 1 is also transmitted from the controller 1a of the spinning machine 1 to the controller 34 of the bobbin conveying device 10.

Next, a method for detecting the processing status of the automatic winder will be described with reference to FIGS.
As shown in FIG. 9, the automatic winder 2 includes a bobbin processing section 2b and a winding unit section 2e. The bobbin processing section 2b has a circulation path 39, and the carry-in conveyor 6 connected to the actual bobbin conveyance path 7a merges with the circulation path 39 and branches off from the middle of the circulation path 39 to form a bobbin processing section. The actual bobbin supply path 2c in 2b is connected. An empty bobbin carry-out path 2d continuing from the winding unit 2e joins with the circulation path 39 of the bobbin processing section 2b, branches from the middle of the circulation path 39, and is connected to the carry-out conveyor 8. The winding unit 2e is formed by connecting a plurality of winding units (not shown) in parallel. Each winding unit of the winding unit 2e has passages 2g, 2g,... That connect the actual bobbin supply path 2c and the empty bobbin carry-out path 2d. A supply amount detection sensor 40 for detecting the supply amount of the actual bobbin B1 is disposed at the end of the actual bobbin supply path 2c of the winding unit 2e, and the actual bobbin circulates in a loop from the end side of the actual bobbin supply path 2c. A path 2f is formed.
Further, as shown in FIG. 10, a bobbin detection sensor 36 that detects an empty bobbin B0 immediately before the empty bobbin carry-out path 2d joins the circulation path 39, and a bobbin stopper that regulates the flow rate of the bobbin B0 to the circulation path 39. 38 is provided.
Further, a full sensor 37 is provided upstream of the bobbin stopper 38 to detect when a predetermined number of empty bobbins B0 have accumulated. The full sensor 37 is activated when an empty bobbin B0 or an actual bobbin B1 in which a yarn remains is detected continuously for a predetermined time or more.

With such a configuration of the automatic winder 2, when the actual bobbin B1 is conveyed from the actual bobbin supply path 2c (FIG. 10) of the bobbin processing section 2b to the actual bobbin supply path 2c of the winding unit section 2e, the winding is performed. If there is an empty space in the passage 2g of the unit portion 2e, the actual bobbin B1 is supplied to the passage 2g. If the passage 2g is full and free, it continues to flow on the actual bobbin supply passage 2c, and is transported without entering the passage 2g until there is a passage 2g with space. Thus, when the actual bobbin B1 passes without entering the terminal passage 2g, it flows into the actual bobbin circulation path 2f. When the supply amount detection sensor 40 of the winding unit 2e detects the actual bobbin B1 flowing into the actual bobbin circulation path 2f, that is, specifically when the actual bobbin B1 is detected a predetermined number of times or more in a predetermined time. The passage 2g is filled with the actual bobbin B1, and the actual bobbin B1 is flowing through the actual bobbin circulation path 2f. The controller 2a determines that the actual bobbin B1 is excessively supplied in the winding unit 2e. To do. Further, when the actual bobbin B1 is detected less than the predetermined number of times in the predetermined time, the actual bobbin B1 is in a state where an appropriate amount is supplied into the winding unit 2e. Therefore, when it is determined that the actual bobbin B1 is excessively supplied, the controller 34 controls the feed amount of the feed means 4 provided in the actual bobbin conveyance path 7a to be reduced.
On the other hand, when the supply amount detection sensor 40 does not detect the actual bobbin B1, since the actual bobbin B1 is insufficiently supplied, the controller 34 increases the feed amount of the feed means 4 provided in the actual bobbin conveyance path 7a. Be controlled.

  Further, the empty bobbin B0 generated after the spinning yarn of the actual bobbin B1 is wound around the package by the winding unit 2e is carried out to the empty bobbin carry-out path 2d in the winding unit 2e. The actual bobbin B1 where the yarn remains may be carried out to the empty bobbin carrying-out path 2d. Then, immediately before the empty bobbin carry-out path 2d that continues from the winding unit 2e joins the circulation path 39, the controller 2a controls the bobbin stopper 38 to open and close so that the empty bobbin B0 is sent out at a predetermined interval. To do. When the processing in the winding unit 2e proceeds and the carry-out amount of the empty bobbin B0 from the take-up unit 2e is larger than the carry-out amount of the empty bobbin B0 in the bobbin stopper 38, the empty bobbin B0 is shown in FIG. As shown in FIG. 10, it is stored on the empty bobbin carry-out path 2d of the bobbin processing section 2b. When a predetermined amount of empty bobbin B0 is stored, the full sensor 37 detects that the empty bobbin B0 is full, and a detection signal is sent to the controller 2a. Based on this detection signal, the controller 2a performs a control to increase the number of times during a predetermined time when the bobbin stopper 38 is opened to increase the feed amount. Control is performed to increase (bobbin transport quantity). That is, the controller 2a grasps the current processing capacity of the automatic winder 2 based on the storage amount of the empty bobbin B0 detected by the full sensor 37. In accordance with the processing capacity of the automatic winder 2, the controller 34 determines the feed amount of the feed means 4, that is, the bobbin transport quantity of the air cylinder 22 in one stroke unit. Furthermore, the bobbin conveyance quantity in units of one stroke of the air cylinder 22 may be determined in accordance with not only the processing capacity of the automatic winder 2 but also the overall situation (a situation including the processing situation of the spinning machine).

Then, according to the determined bobbin transport quantity, the position detection signal from each of the position sensors is used to control the driving of the air cylinder 22 (reciprocating motion with a stroke width corresponding to the designated transport quantity) To repeat). In other words, the controller 34 stops the driving of the air cylinder 22 at any position (one feeding position or two feeding positions) in addition to the origin position in accordance with the bobbin transport quantity (single feed, double feed, etc.). Decide whether or not.
That is, the controller 34 determines the processing status of the automatic winder 2 and the like, determines the required conveyance speed of the bobbin B, and accordingly determines the conveyance quantity of the tray T in one stroke unit of the air cylinder 22. It can be changed. When it is necessary to increase the conveyance speed of the bobbin B, the controller 34 switches the tray T to two-piece feeding and increases the conveyance quantity. On the other hand, when it is necessary to reduce the transport speed of the bobbin B, the controller 34 switches the tray T to single feed and decreases the transport quantity.
Further, by providing a position sensor at a feed position (one feed position or two feed positions in this embodiment) having a different stroke length of the air cylinder 22 as in this embodiment, the feed position of the tray T can be achieved with a simple apparatus configuration. Can be detected.
In the present embodiment, since the feed means 4 is provided with a position sensor, the feed position of the tray T is electrically detected, and the drive and stop of the air cylinder 22 as a drive device are controlled by the controller. It is possible to regulate. Therefore, compared with the feed positioning based on the mechanical position restriction of only the stopper 27, there is no deviation in the feed amount of the tray T, and the conveyance accuracy is increased. That is, the half-feeding, etc., which has occurred in the feed position control depending only on the stopper 27 is eliminated.
In this embodiment, the bobbin B conveyance speed is automatically controlled by the controller 34. However, it is not particularly limited, and the operator grasps the processing status of the automatic winder 2 and the spinning machine 1 and manually manually as needed. A configuration for controlling the conveyance speed of the bobbin B may be used.
In this embodiment, the bobbin B conveyance speed is increased by increasing the bobbin conveyance quantity in one stroke unit. However, as a specific reason for improving the bobbin B conveyance speed, In the case of two feeds compared to the case of single feed, the number of times of switching of the moving direction of the moving member 24 per unit time when the air cylinder 22 is driven to reciprocate is reduced, and switching control is required. This is because the time can be shortened. Further, when the origin sensor and the position sensor are provided, the number of detections per unit time of the origin sensor and the position sensor for detecting the tray T and the time required for the detection can be reduced. For this reason, when the bobbin transport quantity is changed from single feed to double feed in this embodiment, the transport speed is improved by about 20%. On the other hand, if the bobbin conveyance quantity is decreased, the conveyance speed is lowered due to the reverse effect of the reason described above.

Thus, the tray T that has advanced by the length of one stroke of the air cylinder 22 is transported horizontally in the bottom section 19, then ascends the inclined section 18 on the automatic winder 2 side, and enters the connection portion 17 on the opposite side. At the bent portion 21, the actual bobbin B <b> 1 is again changed to a standing posture and is transferred to the carry-in conveyor 6 of the automatic winder 2.
Also, the tray T on which the empty bobbin B0 after being wound around the automatic winder 2 is mounted is lowered in a similar manner from the carry-out conveyor 8 of the automatic winder 2 while being changed in posture by the bypass unit 13, and the feed means 4 When the air cylinder 22 is retracted by one stroke length, the tray T is sent in the conveyance direction A, and is returned to the original posture at the bent portion 21 and then conveyed to the carry-in conveyor 9 of the spinning machine 1.

Thus, in the tray conveyance system having the bobbin conveyance path 10 including the bobbin conveyance path 7 while connecting the automatic winder 2 and the spinning machine 1 with the bobbin conveyance path 7,
The bobbin transport device 10 includes a transport guide member 3 that guides the tray T on which the bobbin B is mounted along the bobbin transport path 7, and a feed unit 4 that includes a moving member 24 that reciprocates to move the tray T. Consisting of
The bobbin transport speed (bobbin transport quantity per unit time) on the bobbin transport path 7 can be changed according to the processing capacity of the automatic winder 2 by changing the bobbin transport quantity in units of one stroke of the feeding means 4. With this configuration, it is not necessary to shorten the stroke interval (increase the moving speed of the moving member 24) in order to increase the conveying speed of the bobbin B, so that the life of the feeding means 4 can be extended. Further, it is not necessary to change the reciprocating speed of the moving member 24 according to the processing capacity or situation of the automatic winder 2, and it is possible to efficiently transfer the bobbin B by changing the bobbin conveying speed. To do. Further, if the change in the transport quantity is made in units of the number of trays T (in this embodiment, one feed or two feeds), the transport quantity can be easily changed, and the controller 34 can reliably and easily perform the automatic winder 2 or the spinning machine. The conveyance quantity of the bobbin B to 1 can be recognized.

  Further, the bobbin transport path 7 has a bottom section 19 which is a horizontal transport section, and the transport surface height of the bottom section 19 is different from the transport surface height of the conveyor of the automatic winder 2 or the spinning machine 1. Thus, the height of the bobbin conveyance path 7 can be appropriately set according to the situation of the installation location of the automatic winder 2 and the spinning machine 1.

  Further, since the bottom section 19 which is a horizontal transport section of the bobbin transport path 7 is arranged underground, it does not become an obstacle between the automatic winder 2 and the spinning machine 1. In addition, a space or the like can be provided on the horizontal conveyance section to effectively use the space.

  Further, in the inclined section 18 which is the bobbin transport path connecting the bottom section 19 which is the horizontal transport section of the bobbin transport path 7 and the conveyor of the automatic winder 2 or the spinning machine 1, the axial direction of the bobbin is horizontal from the upright position. Or, by twisting the tray T so as to stand upright from the horizontal, by making the axial direction of the bobbin B horizontal in the bottom section 19 that is the horizontal transport section of the bobbin transport path 7, It becomes possible to install a conveyance path.

In addition, since the feeding means 4 is provided in the spinning bobbin conveying path 7a for conveying the bobbin B spun from the spinning machine 1 to the automatic winder 2 in the bobbin conveying path 7, the automatic winder is efficiently provided. 2 enables the actual bobbin B1 to be conveyed. Further, since the feeding means 4 is provided in the empty bobbin conveying path 7b for conveying the empty bobbin B0 from the automatic winder 2 to the spinning machine 1 in the bobbin conveying path 7, the conveying capacity is increased and the efficiency is improved. It is possible to transport the empty bobbin B0 to the spinning machine 1.
In the present embodiment, the feeding means 4 is provided at two locations of the forward path 7a and the return path 7b of the transport path 7, but there is no particular limitation, and only one position on the transport path 7 is considered in consideration of the transport capability and the like. It does not matter even if it is the installation of two or more places.

  Further, since the feed means 4 is provided with position detection means for detecting the feed position of the tray T conveyed by the feed means 4 on the bobbin conveyance path 7, the bobbin conveyance quantity by the feed means 4 is detected by the position detection means. Can be recognized. As a result, the bobbin transport speed (bobbin transport quantity per unit time) can be reliably changed according to the processing capacity of the automatic winder 2 or the status of the entire system, so that the entire system can be operated efficiently. it can.

  Further, since the position detecting means is constituted by the origin sensor 31 for detecting the origin of the feeding position of the tray T and the position sensors 32 and 33 for detecting the feeding position of the tray T, the structure of the position detecting means is simplified. it can. Further, it is possible to accurately check the feeding position of the tray T.

  In addition, since the air cylinder 22 is used as the driving source of the feeding means, a complicated driving mechanism is not required and the maintenance can be simplified. Further, since the air cylinder 22 does not output a pressure higher than a specified value, the drive mechanism is not damaged even if an excessive load is generated.
