Next, the second bobbin transfer device 5 will be described. In FIG. 1, a closed-loop overhead rail 95 that returns from the bobbin mounting position P2, which is installed side by side with the roving bobbin removal position P1, to the bobbin mounting position P2 after passing above the creels of the plurality of spinning machines 3, is shown in FIG. 20, 21
The carriage unit 100 as shown in FIG.
It is suspended and guided by 01. Carriage unit 10
0 is constituted by lower and upper carriage bodies 103 and 104, which form vertical and horizontal frames 102a and 102b, respectively, and the lower carriage body 104 is the upper carriage body 1
Rolling roller 106 on the united rail 105 suspended from 03.
The upper and lower carriage bodies 103 and 104 are integrated by the action of a positioning device (not shown) when the upper and lower carriage bodies 103 and 104 are vertically overlapped with each other.

The carriage unit 100 is provided only with bumpers 107 in front of and behind the carriage body 103, and does not have a connecting tool in the carrying direction with another carriage unit 100. Of the horizontal frame 102b of the upper carriage body 103, the one in the front in the transport direction functions as a feed bar hooked by a transport device described later. In addition, the upper and lower carriage bodies 10
As shown in FIG. 21, 3 columns 104 each have four columns L1 to L4.
The bobbin hanger 20 of L4 is suspended and the inner two rows L2
L3 is slightly offset in the traveling direction from the outer two rows L1 and L4. On the upper carriage body 103, five roving guides 108 each having a pair of guide portions 108a are suspended between the inner and outer rows. In this embodiment, since the spinning machine has 200 spindles on one side and 400 spindles on both sides, 10 such carriage units 100 are carried in series above the spinning machine 3 and the spinning creel is directly mounted above the spinning machine 3. Constitute.

The overhead rail portion just before the roving bobbin mounting position P2 is a straight standby rail 95a.
The length of the linear standby rail 95a is at least equivalent to the entire length of the carriage units 100 for 10 units in this embodiment. A transport device 110 of the carriage unit 100 is provided on the linear standby rail 95a, and a guide rail 111 is fixed to the side surface of the linear standby rail 95a as shown in FIGS. A plurality of guide elements 113 attached to the inside of the conveying bar 112 having the same length are slidably fitted into the guide rails 111, so that the conveying bar 112 has a linear standby rail 95.
It is possible to move back and forth along a. At the rear end of the transport bar 112, the feed cylinder 1 mounted on the straight standby rail 95a
Fourteen piston rods 114 a are attached via a connecting plate 115. Is the stroke of the cylinder 114 equal to the total length L of one of the carriage units 100,
Or set a little longer than that.

The carrying bar 112 has a number of 10 corresponding to the number of carriage units 100 waiting on the waiting straight rail 95a via the bracket 116 on the lower surface thereof, that is, ten.
The hooks 117 are supported so as to be swingable in the vertical direction by matching the pitch in the advancing / retreating direction with the total length L of one carriage unit 100. The upper end of each hook 117 rearward from the swing support shaft 118 is formed on a contact surface 117a that contacts the lower surface of the transport bar 112. 1
In FIG. 1, the clockwise rotation is blocked, and therefore, when the transport bar 112 is advanced in this state, the horizontal frame 102b of the upper carriage body 103 is caught and the entire carriage unit 100 can be advanced. The front side of the abutment surface 117a at the upper end of the hook 117 is a relief portion 117b.
Therefore, when the hook 117 is moved backward relative to the carriage unit 100, the hook 117 moves toward the horizontal frame 1
02b and the bumper 107 to rotate counterclockwise,
Due to its own weight, the solid line state of FIG. 11 is obtained.

Next, the first overhead rails 10a-
The bobbin mounting device 120 arranged below the bobbin removing position P1 of 10c and the bobbin mounting position P2 of the second overhead rail 95 will be described. 14 to 16, in the moving base 121 of the bobbin mounting device 120, the wheels 122 provided on the lower surface are moved from the traveling motor 123 to the chain 1.
The wheel 122 is rotated via 24, and the wheels 122 roll on the rail 125 laid between the bobbin removing position P1 and the bobbin mounting position P2 on the floor surface 13, so that the moving base 121 moves between the positions P1 and P2. It reciprocates below. On the moving base 121, the upper and lower carriage bodies 103, 104 slid forward and backward at the bobbin mounting position P2.
Corresponding to the bobbin hanger 20 of FIG. 1, two sets of peg units 126 and 127 for the upper and lower stages are supported by the lifting device 130.

The elevating device 130 includes a first elevating device 133 using two sets of pantograph mechanisms 132 for elevating the intermediate plate 131, and a link-type first elevating device 133 for elevating the upper peg unit 126 with respect to the intermediate plate 131. It is composed of two lifting devices 134. In the first lifting device 133, the rotation of the lifting motor 135 causes the chain 13 to rotate.
6 is transmitted to the feed screw shaft 137. One of the moving elements 139 guided along the rails 138 is screwed with the feed screw shaft 137 across the rails 138 facing each other in the moving direction of the moving base 121, and the other moving element 139 and the connecting rod. They are connected together at 140. Therefore, as the feed screw shaft 137 rotates, the left and right movers 139 slide along the rails 138, whereby the lower ends of the link members 141 pin-supported by the mover 139 and the move base 12 are moved.
The lower end of the link member 142 pin-supported by 1 is moved toward and away from the link member 142, and the intermediate plate 131 is moved up and down.
Of course, the upper end of the link member 143 is pin-connected to the intermediate plate 131, and the upper end of the link member 144 is slidably guided.

The lower peg unit 127 is provided with five rows of pegs 145 at the same pitch as the bobbin hangers 20 of the carriage body 104, and the intermediate plate 131.
Sliding rail 1 provided on a supporting base 146 fixed on the top
The carriage body 10 is longitudinally moved by a feed screw mechanism 150 including a feed screw shaft 149 rotated by a feed motor 148 and movably guided in the longitudinal direction along the carriage body 10.
4 bobbin hangers 20 rows L1 and L2, and L3 and L4
It is designed to move only by the deviation.

Next, the second lifting device 134 on the intermediate plate 131 is similar in structure to the first lifting part 133, although there are differences in the number of links.
The feed screw shaft 153 of the feed screw mechanism is rotated by the driving of No. 1 and the moving element 155 connected to each other by the connecting rod 154.
Is moved along the rail 156 to move the upper plate 157 up and down. Like the lower peg unit 127, the upper peg unit 126 has five rows of pegs 145. The feed screw mechanism 160 by the motor 159 along the slide rail 158 on the upper plate 157 causes the carriage body 103 to move. The respective bobbins hangers 20 are moved between the respective rows L1 and L2, L3 and L4 by a deviation in the carrying direction. In this way, the lower peg unit 127 is moved up and down by the stroke of the first elevating device 133, but the upper peg unit 126 is moved by the stroke of the second elevating device 134 in addition to the stroke of the first elevating device 133. You will be able to raise and lower extra. When the second elevating device 134 is at the lower end, the upper peg unit 126 has the same height as the lower peg unit 127, and in this state, the first elevating device 133 is the bobbin of the lower overhead rail 10c. Both the roving bobbin B of the carriage 23 and the roving bobbin B of the bobbin carriage 23 of the upper rail 10a have removable strokes.

The traveling motor 123 is controlled by operating a switch of a control device (not shown) near the bobbin mounting position P2,
Overhead rails 10a to 1 on either the upper, middle, or lower stage
Stock rails 11a to 1 at the bobbin removal position P2 of 0c
The moving distance is gradually changed between the position directly below the bobbin carriage 23 conveyed from 1c and the position directly below each row L1 to L4 of the bobbin hanger 20 of the carriage unit 100. A step 160 is connected to the rear of the moving base 121 (direction of bobbin device position), and an operator rides on the step 160 to guide the roving bobbin B suspended from the upper carriage body 103 to the roving guide. Perform the work to hang on 108.

At the bobbin mounting position P2, an auxiliary rail 165 used when sliding the upper and lower carriage bodies 103, 104 back and forth at the bobbin mounting position P2 is provided in the cylinder 1.
By the action of 66, the standby position S1 is set along the guide rail 167.
Is provided so as to project and retract between the joining rail 105 of the upper carriage body 103 stopped at a predetermined position and the continuous connecting position S2 (FIG. 15). Further, the carriage bodies 103 and 104 in the slid state are disengaged from the frame, and the carriage bodies 103 and 104 are moved to the bobbin mounting position P2.
A positioning member 168 for positioning is provided so as to project and retract by a cylinder 169.

Next, the operation will be described. The full roving bobbin B formed by the rovings 2a to 2c is taken out sideways onto the conveyor 25. The taken out full roving bobbin B is conveyed toward the machine base end and stops in front of the bobbin pushing device 30. When a detector (not shown) detects that the full bobbin B has stopped,
The pushing cylinder 38 operates to push the roving bobbin B forward. Both ends of the bobbin Bo of the roving bobbin B roll on the guide plate 40, and the bobbin receiver 71 of the roving bobbin transfer device 50.
It is placed horizontally on the upper support roller 76. At this time, the clamp cylinder 79 of the clamp device 78 is in the unclamped state. Next, the advancing / retreating cylinder 55 operates to move the slide base 53 forward (movement indicated by an arrow in FIG. 7), and the elevating cylinder 61 projects to raise the elevating base 57 (arrow). Next, when the roving bobbin B is suspended on the bobbin carriage 23 without changing the winding direction, the rotary actuator 77 is not operated, and when the winding direction is reversed, the rotary actuator 77 is operated to operate the bobbin support 69.
Is rotated 180 ° together with the roving bobbin B (arrow).

Then, in any case, the clamp cylinder 7
The piston rod 79a of No. 9 is projected, and the clamp body 72 in the unclamp position is swung in the bobbin Bo direction against the spring force to clamp the roving bobbin B (arrow). Then, the raising / lowering cylinder 65 is operated to raise the raising / lowering base 63, which was in the horizontal position, to the vertical position. (Arrow). In this state, the shaft center of the roving bobbin B is hung on the overhead rail 10c (10a, 10b), and is vertically positioned above the lifter peg 89 by the pin 21b and an empty bobbin hanger 20 which is previously positioned by a stopper (not shown).
Located directly below.

Next, the raising and lowering base 57 is lowered by the operation of the raising and lowering cylinder 61, and the center hole B3 of the roving bobbin B in the vertical state.
The lifter peg 89 that was at the descending end is fitted in (FIG. 8).
Arrow that shows the operation of. At this time, since the flange 89a of the lifter peg 89 has the cutout 89b,
The tip of the clamp body 72 and the flange portion 89a do not interfere with each other,
The roving bobbin B is placed on the flange portion 89a. When the roving bobbin B is transferred to the lifter peg 89 in this manner, the clamp cylinder 79 retracts the piston rod 79a (arrow in FIG. 8), whereby the clamp body 72 is moved to the roving bobbin B.
Release the clamp. Then, the slide base 53 is retracted to retract the bobbin support 69 to the position of the chain double-dashed line in FIG. 8 in the vertical state (arrow). Next, the lifter peg 89 is lifted to suspend the roving bobbin B on the empty bobbin hanger 20 immediately above, and the bobbin support 69 is rotated by 180 °.
By reversing, the tilting cylinder 65 is retracted, the tilting base 63 is returned to the horizontal position and brought into contact with the stopper 83, and one operation is completed (arrow).

Since the roving bobbin B taken out from the rovings 2a to 2c is in the winding direction of the roving R as shown in FIG. 3, when the bobbin support 69 is not turned, it is like the bobbin at the right end in FIG. When viewed from above, when the roving R is pulled out, the roving bobbin B rotates in the clockwise direction in the clockwise direction, and the bobbin support 69 is rotated.
When 180 ° is turned, the roving bobbin B rotates in the counterclockwise direction, which is the reverse winding direction. 40 full roving bobbins B for one roving machine are thus changed in winding direction, and are suspended from the head of the bobbin carriage 23 in the pattern shown in FIG. 9 as described above.

In this way, the roving bobbins B in the respective rovings 2a to 2c are suspended from the bobbin carriage 23, and are automatically conveyed and stocked by the carriage transfer device 24 to the stock rails 11a to 11c. Even if the doffing timings of the respective rovings 2a to 2c overlap, the overhead rails 10a to 10c of the respective rovings are independent of each other, so that simultaneous doffing and simultaneous transport are possible, and the bobbin carriage 23 can be used.
There is no waiting time for transportation.

Next, based on FIGS. 13, 18 and 19.
The operations of the transport device 110 and the bobbin mounting device 120 of the carriage unit 100 will be described. First, one bobbin carriage 23 is automatically conveyed from any one of the upper, middle, and lower stock rails 11a to 11c, and the bobbin removal position P is obtained.
Stop and position the first 10 pieces to 1. On the other hand, the worker composes a creel with one spinning machine 3, and manually transports ten used carriage units 100 to the standby linear rail 95a by using a hooking portion (not shown). At this time, the ten carriage units 100 are
The piston rod 114a of the feed cylinder 114 is moved forward with respect to the transport bar 112 in the retracted state, and at this time, the hook 117 is rotated counterclockwise by the collision with the lateral frame 102b of the carriage unit 100 and the bumper 107. Each of the ten carriage units 100 moves to stop over the carriage and stops transportation at a position corresponding to the ten hooks 117, and the empty bobbin is removed at this position (FIG. 13).
(A)). Subsequently, the piston rod 114a of the cylinder 114 advances to the forward end according to a command from the operator, whereby the transport bar 112 advances, and the hook 117 hooks the corresponding horizontal frame 102b of the carriage unit 100 and advances. After advancing to the advancing end of the stroke (Fig.
(B)), when retracted, only the rearmost hook 117,
The corresponding carriage unit 100 disappears, and the entire carriage unit 100 is fed forward by one carriage unit 100, and the first carriage unit 100 disengages from the hook 117 and moves to the preparation position P3 which is very close to the bobbin mounting position P2. It is extruded (FIG. 13 (c)). In this state, the operator operates the switch of the control device near the bobbin mounting position P2 to operate the auxiliary rail retracting cylinder 169.
And the auxiliary rail 168 at the standby position S1 is projected to the connecting position S2.

Next, the operator hooks the empty carriage unit 100 at the preparation position P3 using a hooking tool and conveys it to the bobbin mounting position P2, and makes the united rail 105 continuous with the auxiliary rail 165 (FIG. 18). (A)). Subsequently, the worker uncouples the upper and lower carriage bodies 103 and 104, slides the lower carriage body 104, and suspends it from the auxiliary rail 165. In this state, by operating the switch of the control device, the upper and lower carriage bodies 103, 104
The positioning members 168 respectively project toward and position the upper and lower carriage bodies 103, 104. Further, by operating the switch of the control device, the lower overhead rail 10c
The first and second lifting devices 133, which were at the descending end immediately below the
Of the 134, only the first lifting device 133 moves up and down to move the bobbin carriage 23 of the lower overhead rail 10c.
The first 10 roving bobbins B of the peg unit 12
Remove on peg 145 of 6,127. When the roving bobbin B of the bobbin carriage 23 of the middle and upper overhead rails 10b and 10c is to be picked up, the entire bobbin mounting device 120 is moved to a position directly below the bobbin mounting device 120 and then the peg units 126 and 127 are moved up and down. Needless to say.

The bobbin mounting device 120, which has received the ten roving bobbins B in this way, has the carriage bodies 103, 10
4 is moved to a position immediately below the innermost row L1 of 4 and stopped. Here, the first and second elevating devices 133 and 134 are moved up and down, and the upper peg unit 126 is changed to the lower peg unit 12.
Ascends above 7 to reach each peg unit 126, 12
Each of the five roving bobbins B on 7 is hung simultaneously on the empty bobbin hangers 20 of the upper and lower carriage bodies 103 and 104 (FIG. 18B).

Next, before the bobbin mounting device 120 returns to the position immediately below the lower overhead rail 10c, the next ten roving bobbins B suspended on the bobbin carriage 23 of the rail are automatically conveyed to the bobbin removal position P1. As described above, the first and second lifting devices 133 and 134 and the bobbin mounting device 1 are also provided.
By moving 20 itself, the bobbin carriage 23 is mounted on the second row L2 from the back of the carriage bodies 103 and 104 (FIG. 18D). After that, the same operation is repeated, and the 40 roving bobbins B suspended from the bobbin carriage 23 in a single row are mounted on the upper and lower carriage bodies 103 and 104 in four rows of five (FIG. 19 (a)). still,
In the case of the rows L2 and L3, since there is a deviation in the transport direction with respect to the rows L1 and L4, the peg units 126 and 127 are moved by the feed screw mechanisms 150 and 160 after the roving bobbin B is removed from the bobbin carriage 23. Then, after correcting the deviation, suspend it. In this way, when the roving bobbin B is automatically transferred, the operator rides on the step board 160 and the roving R of the roving bobbin B of the upper carriage body 103 is moved.
Is hung on the corresponding roving guide 108. At this time, the roving thread end of the roving thread bobbin B of the lower carriage body 104 is placed on the upper surface of the roving thread bobbin B. Then, the positioning member 168 is retracted, the lower carriage body 104 is slid to overlap the upper carriage body, and the two are combined, and the auxiliary rail 165 is retracted, and then the carriage unit 100 on which the roving bobbin B is suspended is installed. It is sent out from the bobbin mounting position P2 toward the spinning machine 3.

The bobbin carriage 23 is automatically conveyed to the original stock rail 11c when the last ten roving bobbins B that have been suspended are taken up by the bobbin mounting device P2, and the next new roving yarn is replaced. Since the bobbin carriage 23 that suspends the bobbin B is automatically conveyed to the bobbin removal position P1, the worker who has sent out the carriage unit 100 having the roving bobbin B mounted thereon can carry the next empty carriage unit 100. It is necessary to provide the operation support to the transport device 110 of the carriage unit 100 prior to this, but the feed cylinder 114 reciprocates once and the head of the remaining empty carriage unit row always moves to the preparation position P3. Therefore, the operator attaches the bobbin at the mounting position P.
It is sufficient to walk a short distance from 2 to the preparation position P3, and the operator's fatigue can be reduced.

In this embodiment, the system in which the bobbin of the first overhead rail is automatically transferred to the two upper and lower carriage units has been described. However, as in Japanese Patent Laid-Open No. 2-270766, a roving bobbin is used. Can also be applied to a system in which an operator places it on the bobbin lifter and mounts it on the carriage unit at the bobbin mounting position. Further, here, the carriage unit is composed of upper and lower two-stage carriage bodies, and the creel is configured in the spinning machine as it is, but the carriage unit also includes a type having a plurality of bobbin hangers in one row. . Further, in the present embodiment, an example in which the bobbin is mounted before the bobbin mounting position has been described, but it goes without saying that it can be applied to other overhead rail portions.

[0039]

As described above, according to the apparatus of the present invention, a plurality of carriage units whose hooks are not connected to each other can be moved forward by a predetermined length only by the forward / backward movement of the forward / backward drive source. The configuration can reduce the labor of manual transportation. In particular, when it is installed on the straight standby rail near the bobbin mounting position, the leading carriage unit is constantly located close to the bobbin mounting position. The length can be shortened, the walking distance of the worker can be shortened, and the burden on the worker can be reduced.
