[0030] The above base plate (52) is equipped with a bobbin (Ba1) at the tip of the chute (43). The bobbin passage hole (51) described above is formed on one side as a gap, and the bobbin passage hole (51) described above is formed on the other side as shown in the paper of FIG. The concave part (55) for the passage of the conveyor belt (45) for conveying empty trays that runs in the front and rear direction is It is formed. On the base plate (52) above, guide the slider (53). The half-shaped fixing guides (56a)(56b) are attached to the screws (57)(58)(61) and the fixing piece (59). )(60) etc., and are integrally fixed and installed to form a slide guide.

[0031] The upper surface of the slide guide has guide pieces (62a) (62b) fixed to the upper surface of the slider. ) A long groove (63) of width (b1) is formed for passage. Furthermore, the above fixation in FIG. On the guide (56b) side, there is a notch (64) for passing the tray that slides from the chute (43). ) is formed as shown in FIG.

[0032] On the other hand, the slider (53) has a U-shape that opens downward when viewed from the side in FIG. The upper plate (65) has a chute (43) in the standby position. A cutout (67) having an opening that coincides with the tray passageway (66) and a cutout (67) connected to the cutout (67). It has a notch (68) formed in a right angle direction. Also, the slider above (53) The lower end of the bobbin (Ba) and the tray ( A guide piece (TA) that enters between the guide pieces (TA) and guides the bobbin to forcibly separate it from the tray. 62a)(62b) are fixed.

[0033] The bobbin moves upward along the inclined surface (69) of the guide piece (62a) (62b), and The support material (70) at the bottom of the tray (described later) moves and the tray is attached to the base plate (52). After falling upward, the bobbin slides further over the guide pieces (62a)(62b) and slides down. into the bobbin receiving hole (72) of the slider block (71) fixed to the slider (53). I will lower it. There are tray support materials on both side walls (72) (73) of the slider (53) above. (70)(70) is fixed and temporarily supports the tray fed from the chute (43). Ru. As the slider moves in the direction of the arrow (74) in Figure 11, the supporting members (70) and (70) also move. By moving and finally moving to a position away from the bottom surface of the tray (TA), the tray The Ray (TA1) no longer has any support members, so the lower base plate (52 ) it falls upwards.

[0034] Furthermore, a cylinder arm (76) is fixed to one end surface (75) of the slider (53). fluid system attached to the fixed guide (56a) via brackets (77)(77). One end of the above cylinder arm (76) is attached to the piston rod (78) of the cylinder (54). The slider (53) moves at a constant stroke as the piston rod (78) moves back and forth. The rotor reciprocates in the left and right direction in FIGS. 11 and 12. That is, slider 1 One bobbin is separated from the tray by the stroke and placed in the bobbin storage section on the winder side. At the same time, the empty tray is transferred onto the conveyor (45), and the empty tray is transferred to the conveyor (45). It is returned to the transport conveyor (FIG. 8 (R1)).

[0035] The effect of the above slider will be explained. In the state shown in Figures 10 and 11, the slider - The first tray in the inclined chute (43) is placed above the tray support material (70) (70) of (53). If the bobbin is entered under its own weight, there is no bobbin in the specified position in the bobbin storage section on the winder side. The cylinder (54) in Fig. 10 starts operation by confirmation of , bobbin request command signal, etc. start

[0036] FIG. 13 shows a state in which the piston rod has advanced to an intermediate position. That is, sly As the slider (53) moves, the tray support member (70) integrated with the slider moves the tray ( The tray (TA) reaches a position away from the bottom surface of the base plate (TA). 52) Fall upward. At this time, the bobbin (Ba1) is the lower end surface of the bobbin of the slider (53). from the top plate (79)(79) to the sloped surface (69) of the guide piece (62a)(62b). It moves relatively and moves along the bobbin guide plate (80) that is integrally installed on the fixed guide (56b). It moves slightly upwards. At this time, the side wall of the slider (53) on the chute (43) side Because the tray passage opening (81) formed in (73) deviates from the chute position, The succeeding tray (TA2) in the tray hits the side wall (73) of the slider as shown in Figure 12. They are blocked from entering.

[0037] Subsequently, the slider (53) further moves forward and reaches the position shown in FIG. 14. Piss at this time Tonrod is the most advanced position. The tray that fell onto the base plate (52) A (TA1) is pushed by the front (82) of the block (71) which is integrated with the slider (53). The empty tray is moved to the left and transferred onto the inclined conveyor (45) for carrying out the empty tray. Further above When the block (71) moves while pushing the empty tray, the bobbin (B) on the top of the slider a1) is prevented from moving by the bobbin guide (80), and the guide piece (62a) ( 62b) and fall into the bottomless hole (71) formed in the block (71), and the base It is placed on the spray plate (52).

[0038] Then, as the piston rod retreats, the slider (53) moves toward its original position. The bobbin (Ba1) in the block (71) slides on the base plate (52). Move one step to the right, and when you reach the position shown in Figure 15, the hole (72) of the block (71) and the wine The moment the bobbin chute (82) connected to the bobbin storage part of the driver aligns, the block ( The bobbin (Ba1) in 71) passes through the bobbin passage hole (51) of the base plate (52). and falls into the bobbin chute (82). At this time, the slider (53) The empty tray (TA) passes through the empty tray passage hole (81) formed in the side wall (73) on the 1) is transported on the conveyor (45). The other tray passage hole (83) also has a chute. Because it matches the tray passage hole of similar shape formed in the fixed guide (56b) on the side, the system Tray (TA2) with the next bobbin (Ba2) waiting on the mute (43) will enter onto the tray support member (70) of the slider (53), and again as shown in Figure 10. The machine is now ready for the next bobbin supply.

[0039] Note that the bobbin chute (82) in Figure 15 above is continuous with the chute (82) in Figure 8. The bobbin falling through the chute is one of the bobbins in the bobbin storage section (44) in FIG. is supplied to the container storage can (84). When the bobbin is supplied to the storage can (84), it is stored. The reservoir (44) rotates one pitch so that the next storage can (85) is located directly below the chute. controlled by.

[0040] The operation of the bobbin conveyance system having the device as described above will be described next.

[0041] At the bobbin supply station (ST1A) (ST1B) in Figure 1, Bobbins of different types are supplied to trays dedicated to the bobbins, and in this example, bobbins of type A and type B are supplied. Bobbins of different types are inserted into dedicated trays and passed on a common bobbin transport path (F1). Delivered randomly. The above bobbin replenishment station (ST1) is For example, the bobbin supply device disclosed in Japanese Patent Application Laid-Open No. 60-48871 is applicable. It is also possible to connect directly to a spinning machine.

[0042] The various bobbins mentioned above are equipped with a yarn end feed device (S T2), the bunch winding is unwound and the thread end is held in the appropriate position on the bobbin. It is transported to the winder in the same condition. In addition, as the above-mentioned pick-up device, for example, The device disclosed in Japanese Unexamined Patent Publication No. 59-69372 is applicable.

[0043] Subsequently, the bobbin is transported in the direction of the arrow (26) along the transport path (F1) as shown in FIGS. 2 to 5. The material is transported on the vertical transport path (F2) shown in the figure, and then transferred onto the horizontal transport path (F3) above. It will be done. Note that the axis of the bobbin is almost horizontal while it is being transferred through the vertical conveyance path (F2). However, as shown in Figure 5, the tray consists of the friction body (24) on the belt and the guide plate (21) (2 2) Since the peg (84) is transported while being held between them, the peg (84) may tilt downward from the horizontal. There is no possibility that the bobbin will fall off from the peg (84). In addition, even cheaper In order to ensure completeness, it is also possible to provide a cover over the entire vertical conveyance path. .

[0044] The bobbin transferred to the conveyance path (F3) as described above is indicated by the arrow (85) in Fig. 1. The bobbin is transported in the direction of the winder, and at the first branch point, the bobbin is sorted. It will be done. That is, by the sorting device shown in FIGS. 6 and 7, only bobbins of type A are sent to the branch path. It is sorted and transferred to (f1) and slides on the chute (43). In the case of this example, Only trays that do not have identification grooves (TA), that is, type A bobbins, can be (43) has been moved above. Of course, the gauge plate (29) in Figure 6 is connected to the passage (33). If it is installed on the opposite side of the It is transferred into the container (43).

[0045] In this way, the A type bobbin is placed inside the chute (43) in Figure 1. 43b), bobbins of type B are neatly stocked as shown in Figure 8. Therefore The same type of bobbin is supplied to each winder (WA) (WB), and bobbins of other types are mixed. It never exists.

[0046] In each winder, as the winding operation progresses, from the bobbin storage section (44) Bobbins are supplied to each winding unit by known means, and the bobbin storage section (44 ), the bobbin is separated by the bobbin separation device (50) shown in FIGS. 10 to 12. Supplied separately from the ray.

[0047] The empty tray (TA) is transported along the inclined conveyor (45) as shown in Figure 8. (R1) and transferred onto a common conveyance path (R1). Conveyance path (R1) On top, trays for A type and B type are conveyed randomly, and a descending vertical It is transferred to the lower transport path (R3) in FIG. 1 via the direct transport path (R2). sky above Empty trays transferred from the tray conveyance path (R3) in the direction of arrow (86) in Figure 1 are Sorting to the bobbin supply station (ST1A) (ST1B) in the same manner as in Figures 6 and 7 above. The trays are sorted and transferred by the device, completing one cycle of tray bobbin transfer. Complete. In this way, the trays correspond to specific bobbins one after another in the winder. It is supplied to

[0048] The above example shows a system that supplies two types of bobbins to two winders. However, of course, it is also possible to supply bobbins of 3 or 4 types to 3 or 4 winders. This is possible with a similar system. Furthermore, it can be used as an existing winder. If the unit is fixed, each winding unit has multiple magazines. It is also applicable to winders that use That is, following the branch road (f1) in Figure 1, An endless conveyor is provided that runs along the winding unit, and A branch path that branches the bobbin from the winding unit to the magazine of each winding unit, and the corresponding branch. If a movable guide is provided at the turning point so that it can be opened and closed, a specific bobbin can be attached to a specific winder. can be supplied.

[0049] Furthermore, as a means for separating the bobbin from the above-mentioned tray which is the bobbin transport medium. , instead of the separating device shown in Figures 10 to 12, a bobbin at the front end of the chute (43) Grip the empty tray with the chuck and drop it into the bobbin chute (82), then transfer the empty tray to the transfer controller. Devices such as a pusher that pushes toward the bare side can also be used to separate bobbins and empty trays. Transport is possible and is not limited to the device shown.
