When the crank 14.15.18.19.21 rotates,
The cranks 27 to 31 also rotate in conjunction with each other. Hereinafter, with reference to FIG. 7, the gripping mechanism in the hanging portion 52 will be explained.

When the crank 29 rotates in conjunction with the rotation of the crank 14, the connecting rod 34 is pulled upward and moved. The crosshead 39 at the end of the connecting rod 34 also moves upward in conjunction. Gripping piece 58.59
is rotated by the bins 46, 47 from the position shown by the solid line to the position shown by the two-dot chain line, and the stopper bins 82, 83 come into contact with the stopper 89 and come to rest. When the stopper bins 82 and 83 come into contact with the stopper 89, the gripping piece can support the load of the real bobbin W.

When each member is in the above-mentioned position, when the motor M rotates in the opposite direction (solid line direction), the connecting rod 12 is pushed and moved to the left, and the connecting rod 34 is also pushed downward. to push down the crosshead 39, and the gripping pieces 58, 59 return to their original solid line positions.

The above action is carried out by the hanging parts 50, 51, 53. The same applies to the gripping mechanism No. 54. In this way, each gripping mechanism of the bobbin carrier 1 of this embodiment, which combines a plurality of connecting rods and cranks, is simultaneously driven by a single motor M without requiring a plurality of drive sources. Therefore,
The gripping work can be easily controlled, and motors, wiring, etc. can be saved.

In addition, when the gripping surfaces 55a to 62a of each of the gripping pieces 55 to 62 are in the posture of gripping the real bobbin W, the portions near the tip are horizontal, and the portions near the hanging portions 50 to 54 are inclined. Four sets 55 of opposing gripping pieces
In 56.57, 58.59, 60.61 and 62, the distance from the boundary between the horizontal surface and the inclined surface of one gripping piece to the boundary of the other gripping piece is the same as the length C of bobbin B. Therefore, the real bobbin W can be held in an accurate posture and position,
can be released.

Next, the structures of two types of transfer stations will be explained. 8 to 10 show a full bobbin carrying-in station and an empty bobbin carrying-in station, and FIGS. 11 to 13 show a real bobbin carrying-in station and an empty bobbin carrying-out station.

In FIGS. 8 to 10, a full bobbin carry-out/empty bobbin carry-in station 201 is installed adjacent to a real bobbin production device (not shown). Therefore, the actual bobbin is sent to the next process, and the processed empty bobbin is taken from the next process.

202 is a real bobbin transfer port, and the real bobbin sent from the real bobbin production process is placed on the conveyor 203. The real bobbin W placed on the conveyor 203 is sent to the conveyor 204.

206 and 207 are empty bobbin receiving troughs, and conveyor 2
Connected to 08. At the end of the conveyor 208, there is a stopper 209, a cylinder 210, and an empty bobbin delivery gutter 21.
1 is provided. The empty bobbin delivery gutter 211 is connected to a real bobbin production process (not shown).

212 to 215 are guide rods each having a tapered tip. 21G and 217 are abutment rods, and abutment members 218 and 219 are provided at their tips, respectively.

Next, a transfer operation at the illustrated real bobbin unloading/empty bobbin loading station 201 will be explained.

The real bobbins W brought from the real bobbin production process are loaded onto the conveyor 203 from the real bobbin transfer port 202 at equal intervals. The real bobbin W maintains even front and rear spacing,
It moves to the right in FIG. 8.9 and reaches the unloading position on the conveyor 204. 4 on conveyor 204
Two real bobbins W are lined up at equal intervals.

The overhead vehicle V travels with the bobbin carrier l raised, and the four real bobbins W on the conveyor 204 are located directly below the gripping portions 2a to 2d of the bobbin carrier 1, that is, the four The actual bobbin stops at a position where it is sandwiched between each of the hanging parts 50 to 54. At this time, the basket 3a.

Two empty bobbins B are stored in 3b. Further, when the vehicle is running, each of the gripping pieces 55 to 62 is in a retracted position.

When the overhead traveling vehicle V stops at a predetermined position, the lifting mechanism in the overhead traveling vehicle main body 102 is driven to lift the belts 103 to 106.
, and lower the bobbin carrier 1. Bobbin carrier 1
As it descends, each guide hole 98.99.100.1

is inserted and accurately positioned.

The bobbin carrier 1 descends until each of the gripping pieces 55 to 62 reaches the height A shown in FIG. In FIG. 14, only the operation of the gripping piece 59 is shown.

When the gripping piece 59 reaches the height A, the gripping mechanism described above rotates the gripping piece 59 and displaces it to the posture shown by the two-dot chain line.

Then, the bobbin carrier 1 is pulled up by the lifting mechanism of the overhead vehicle V, and the gripping piece 59 rises to the height B.
The real bobbin W is gripped.

Further, the bobbin carrier 1 is pulled up to the highest point by the lifting mechanism, and the overhead traveling vehicle V grips the actual bobbin W and starts moving.

Further, the empty bobbins B stored in the baskets 3a and 3b of the bobbin transport body 1 are automatically transferred to the station when the bobbin transport body 1 is lowered.

As shown in FIG. 10, each end 3a, 3b has a protrusion 3c,
3d, and as the bobbin conveyor 1 descends, the protrusion 3c
, 3d abut against the abutting members 218, 219. Therefore, each end 3a, 3b rotates in the direction of the arrow around the shaft 96,
tilt. The empty bobbins B, which have been stored on the left side of each end 3a, 3b, roll due to the rightward inclination and are delivered to the empty bobbin receiving troughs 206 and 207. The empty bobbin B further rolls on the empty bobbin receiving gutter 206, is placed on the conveyor 208, is conveyed to the left in FIG. 8, and comes into contact with a stopper 209 and stops. The empty bobbin B is then pushed by the cylinder 210 and placed on the empty bobbin delivery gutter 211, and is supplied to the actual bobbin production process.

As described above, at the real bobbin carry-out/empty bobbin carry-in station 201, the real bobbin carry-out work and the empty bobbin carry-in work are performed simultaneously.

Next, the actual bobbin loading/empty bobbin loading station 301
We will explain the structure of

In FIGS. 11 to 13, a full bobbin loading/empty bobbin unloading station 301 is adjacent to a processing step (not shown) in which yarn, which is a semi-finished product, is unwound and processed after being wound around a real bobbin. Therefore, it is a station that is supplied with real bobbins from the previous process and sends empty bobbins back to the previous process.

In each figure, 302 is an inclined plate on which the transported real bobbin W is placed, and is connected to a conveyor 303 at the bottom.

Above the conveyor 303 are two empty bobbin storage baskets 30.
4.305 is provided.

Each empty bobbin storage basket 304, 305 is inclined to the left in FIG.
．． It is designed to stop at 307 and store empty bobbins B. The right end is open. Each stopper 306.307
The shafts 306a, 306a are connected by springs (not shown).
, 307a, and 307a are biased in a direction to rotate upward.

308 to 311 are guide rods.

Next, the transfer work at this station 301 will be explained.

The overhead vehicle (2) suspends four real bobbins from the bobbin carrier 1 and stops at a predetermined position above the station. At this time, no empty bobbins are stored in the baskets 3a and 3b.

After the overhead vehicle V stops, the bobbin carrier 1 descends. At this time, the guide rods 308 to 311 are inserted into the guide holes 98 to 101 of the bobbin carrier 1, so that the precision is
It can be positioned in the same way as the station 201.

The bobbin carrier 1 has each gripping piece 55 at the height of A in FIG.

Then, by the gripping mechanism, the gripping piece 59 located at the position shown by the two-dot chain line is rotated in the direction of the broken line arrow to the position shown by the solid line, and the real bobbin W is released.

The released real bobbin W rolls on the inclined plate 302, is placed on the conveyor 303, and is transported to the real bobbin processing step.

On the other hand, the empty bobbins B stored in the bobbin storage baskets 304 and 305 are automatically transferred to the basket 3a when the bobbin carrier 1 is lowered.
, 3b.

When the bobbin carrier 1 descends, the basket 3a.

The protruding portion 3e at the right end of FIG. 13 of 3b.

3e, 3f, and 3f are stoppers 306a.

307a, each of the stoppers 306 and 307 is pushed down and displaced to the position shown by the two-dot chain line. Therefore, the empty bobbins B stored in the empty bobbin storage baskets 304 and 305 are released from the stoppers 306 and 307 and roll into the baskets 3a and 3b.

In this manner, at the full bobbin loading/empty bobbin unloading station 301, the actual bobbin loading operation and the empty bobbin unloading operation can be performed simultaneously.

As described above, according to the system of the present embodiment, a full bobbin is carried in and an empty bobbin is carried in at one station, and a real bobbin is carried in and an empty bobbin is carried out at one station. This will reduce the number of stations and reduce the number of starting and stopping times for autonomous vehicles.
Moreover, since the real bobbin and the empty bobbin can be loaded and unloaded simultaneously, labor and time can be saved and the system can be made more efficient. The system will also be more efficient in that self-driving cars will never run without carrying anything.

Further, in the above-mentioned transfer operation, the loading and unloading of the real bobbin and the loading and unloading of the empty bobbin are simultaneously and automatically performed by raising and lowering the lifting platform, so there is no need for complicated control.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above embodiments, and can be modified as appropriate within the scope of the gist of the present invention.

(Effects of the Invention) According to the bobbin conveyance system of the present invention configured as described above, it is possible to save labor and time in the transfer operation and to improve the efficiency of the conveyance system. Moreover, the automatic driving vehicle does not run idle.
