When returning to the above, the same information is written to the storage medium 66 in FIG.

The first and second storage conveyors 3 and 4 are connected on the way to the connection section X between the overhead conveyor 11 and the tray circulation conveyor 5 and each have a storage section composed of upper and lower two-stage intermittent operation conveyors. . In the first storage conveyor 3, the packages are transferred via the lifting / lowering lifts 14, and the packages of the type A are sorted in the upper stage, and the packages of the type B are sorted in the lower stage and stored in a horizontal line. Also in the second storage conveyor 4, the packages are transferred via the lifting / lowering lifts 15, the packages of the C type are stored in the upper row in a horizontal line, and the lower row is reserved. Also, one end 3a, 4a of the storage conveyor 3, 4
Is a package entrance and exit.

At a connection portion X between the overhead conveyor 11 and the tray circulation conveyor 5, a lift 16 and a transfer device 20 are installed. The lift 16 passes the package received from the hanger of the overhead conveyor 11 to the transfer device 20, and the transfer device 20 inserts the package into the tray. The tray circulation conveyor 5 has an empty tray return line 21 → a storage line 22 → an inspection line 23 →
A circulation line is formed from the alignment line 24 to the empty tray return line 21, the transfer device 20 is provided at the end of the empty tray return line 21, and the inspection line 23 is provided with the inspection device 6 common to all types of packages. ing. In addition, 25 is a bypass line. The alignment line 24 aligns the inspected packages in five rows. As shown in detail in FIG. 3, the inspection line 23 is configured by, for example, a belt conveyor, and the trays 25 in which the packages P are inserted by the stopper 70 at the end are aligned in a line. A pusher device 71 is provided along the inspection line 23 and reciprocates in the direction of arrow c, thereby forming five trays 25 in one row.
Are extruded all at once. The alignment line 24 is formed of, for example, a roller conveyor, and the trays 25 are sequentially fed in the horizontal direction. The package P is removed in the middle of the lateral feeding, and the tray 25 becomes empty. Return line 21
Is constituted by, for example, a belt conveyor, and conveys empty trays 25 which are simultaneously pushed out from the alignment line 24. In addition,
Under the control of the stopper 72 at the entrance, it is arranged in a line,
The number of trays 25 pushed out by the pusher device 71 can be set to, for example, four.

A rail 9 is laid directly above the alignment line 24 of the tray circulation conveyor 5, the palletizing table 7, and the pallet parts placing table 8, and the first ceiling transport vehicle 10A and the second ceiling transport vehicle 10B connect the rail 9 to the rail 9. It is provided so that it can run freely. This part will be described in more detail with reference to FIG. In the alignment line 24, 5 of the package inserted in the tray 25
Individuals are sequentially arranged in multiple rows. On the lift 26 of the first ceiling carrier 10A, two rows of five chucks 27 project downward. Therefore,
The first ceiling carrier 10A is 5 pieces x 2 rows or 5 pieces x 1 at a time.
The packages in the row can be removed from the tray 25 and transported. On the palletizing table 7, a bottom plate 28 is placed.
5 × 5 = 25 packages on 8 are aligned. Further, the middle plate 29 is placed, and the packages are aligned on the middle plate 29. In the illustrated example, when the first ceiling transport vehicle 10A transports the remaining five rows, 5 × 5 = 25. Second
The ceiling transport vehicle 10B transports the bottom plate 28, the intermediate plate 29, and the top plate 30, which are stacked on the pallet component placing table 8, to the palletizing table 7 in a desired order. Have been. Note that, when the packages on the alignment line in FIG. 3 are aligned in four rows, palletizing of 4 × 4 pieces is possible. In this case, by not operating a part of the chuck of the first ceiling transport vehicle 10A, it is possible to cope with four transports.

Next, the procedure of transporting a package by the above-described package transport system will be described with reference to FIG. The automatic winder 1 and the pneumatic spinning machine 2 are normally operated for 24 hours, but the inspection device 6 and the palletizing table 7 are appropriately operated by an operator during the normal 8-hour operation. for that reason,
When the inspection device 6 and the like are not moved, it is necessary to store the packages from the automatic winder 1 and the air spinning machine 2 so that the type can be identified. Therefore, overhead conveyor 1
Convey while storing in the 1 hanger. As described above, the storage medium is provided on the hanger, and the type of the package and the like are written therein. Therefore, automatic winder 1
A, B, and C types from the air spinning machine 2 and the D type packages from the air spinning machine 2 are stored in the overhead conveyor 11 in a random state. However, for example, when doffing of the automatic winder 1 is concentrated, the automatic winder 1 may overflow from the overhead conveyor 11. In this case, the lifting / lowering lift 14 selects the type A package of the automatic winder 1 and stores the package in the upper stage of the storage conveyor 3 via the lifting / lowering lift 14. Similarly,
The package of the B type of the automatic winder 1 is stored in the lower stage of the storage conveyor 3, and the package of the C type of the automatic winder 1 is stored in the upper stage of the storage conveyor 4.
The lower stage of the storage conveyor 4 is reserved. Thus, the storage conveyors 3 and 4 are buffers for storing packages. When the number of packages on the overhead conveyor 11 decreases due to the operation of the inspection device 6, the packages are returned from the storage conveyors 3 and 4 to the overhead conveyor 11. At this time, what kind of packages are arranged in order in the storage conveyors 3 and 4 is stored in the control device, and data such as product type is written to the storage medium 66 in FIG. .

When the inspection device 6 is operated, for example, the D type is sequentially transferred from the overhead conveyor 11 to the storage line 22 of the tray circulating conveyor 5 via the lifting / lowering lift 16 and the transfer device 20, and a predetermined inspection is performed. . The packages that have passed the inspection and pass are aligned in five rows on the alignment line 24, and are transported by the first ceiling transport vehicle 10A in five rows, two rows, or five each. On the palletizing table 7,
The bottom plate 28 is placed, the packages are arranged in 5 × 5 = 25 packages, the middle plate 29 is placed to further align the packages, and finally the top plate is placed and packed. In addition, on the overhead conveyor 11, packages of the A type are returned from the storage conveyor 3 to the overhead conveyor 11 via the elevating lift 14. Then, the package of the A type is inspected. Similarly, the packages of the B type and the C type are inspected. An operator manually transports a package of a specific type from the other end 3b, 4b of the storage conveyor 3, 4 to the entrance of the storage zone 22 of the tray circulation conveyor 5 using a wagon or the like, and manually inserts the package into the tray. You can also make it stand. In this case, it is preferable to arrange the storage conveyors 3 and 4 so that the other ends 3b and 4b of the storage conveyors 3 and 4 and the connection portion X are as close as possible. Thus, based on the simple transport system for transporting and storing the packages on the overhead conveyor 11, the simple storage conveyor 3,
4 is a transport system that has an effective buffer function, it takes a long time to form a package with thin yarn,
It is most suitable for the transport system which is most suitable for producing small lots of many kinds.

Next, an example of the structure of the storage conveyors 3 and 4, which are the main parts of the present system , will be described with reference to FIGS. FIG. 5A is a front view of the storage conveyors 3 and 4,
FIG. 5B is a side view. First, in FIG.

6 is attached so as to be able to ascend and descend along a column 37. Data such as the type of the package hung on the hanger 62 of the overhead conveyor 11 is written in the storage medium 66, and the type of the package is selected by the read / write device 68 provided in the lifts 14 and 15. If the package is of a predetermined type, the user moves onto the swivel base 35 that has been raised to the position indicated by the two-dot chain line. Then, the swivel 35 turns 90 ° and the lift 36 descends.

The storage conveyors 3 and 4 have a structure in which two upper and lower storage sections 41 and 42 are supported by columns 40.
The storage portions 41 and 42 are formed by extending two round belts 45 between two turn pulleys 43 and 44. The round belt 45 can travel at every pitch P by a driving device (not shown). As shown in FIG. 6, guide rods 46 are arranged at predetermined intervals below the two round belts 45,
Side guides 47 are also provided on both sides of the two round belts 45. The packages P are stored in a state of being placed horizontally on the round belt 45, and the packages are simultaneously transported in the direction of arrow b in FIG.

By the way, in the two upper and lower stages, the packages from the lifts 14 and 15 are selectively stored in the storage sections 41 and 4.
It is necessary to have a structure that can be loaded into the 2. The structure will be described below. A swing table 51 is provided at one end of the upper storage section 41. The swing table 51 is pivotally supported at the upper end of the parallel link 52, and the lower end of the parallel link 52 is pivotally supported by a bracket 53 extending from the support column 40, and an air cylinder 54 is attached to one lower end extension 52 a of the parallel link 52. Are linked. When the air cylinder 54 is shortened, the swing table 51 is at the position indicated by the solid line and receives the packages from the lifts 14 and 15. Therefore, as shown in FIG.

When the user lowers the swivel base 35, the package becomes a small circle belt 58.
It is designed to move on top of

The operation of the storage conveyors 3 and 4 having the above structure will be described with reference to FIG. When storing the package P in the upper storage section 41, the swing table 51 is located at the position indicated by the solid line, and the lift 3 is held while the package P is mounted on the swivel table 35.
6, the package is transferred from the swivel table 35 to the swing table 51. At the same time as the swing table 51 swings to the position indicated by the two-dot chain line, the round belt 45 runs intermittently by the pitch P, the package is placed on the round belt 45, and the swing table 51 returns to the original solid line position. . Meanwhile, the lift 36 moves up and receives a new package P from the overhead conveyor 11. Then, the lift 36 descends. By repeating the above, the packages P are stored in a line in the upper storage section 41.

When a package of another type is stored in the lower storage section 42, the swing table 51 of the storage section 41 is retracted to the position indicated by the two-dot chain line. When the swivel table 35 on which the package P is placed is lowered, the swivel table 35 passes through the storage unit 41 and is stored in the storage unit 4.
The package P is transferred onto the second small circle belt 58. When the round belt 45 of the storage section 42 runs by the pitch P, the small round belt 58 also runs, and the state shown in FIG. Then, the lift 36 moves up and receives a new package P from the overhead conveyor 11. Then, the lift 36 descends. By repeating the above, the packages P are stored in a line in the lower storage section 42.

Further, the packages from the storage units 41 and 42 can be selectively returned to the overhead conveyor 11 in an operation completely opposite to the operation for storage. In this case, the direction of the hanger 62 is reversed by 180 ° using the cross bar 67.
Then, the data such as the type of the package is written into the storage medium 66 again by the read / write device 68. That is,
The swing table 51 and the small round belt 58 at one end of the storage conveyors 3 and 4 function as a carry-in / carry-out port.

As described above, the overhead conveyor 11
Overflows, the packages can be selectively stored in the upper and lower storage sections 41 and 42 of the storage conveyors 3 and 4, and can be returned to the overhead conveyor 11 as needed. Since there are two upper and lower stages, space can be saved, and since the package is placed horizontally, it can be stored in a packed state. It should be noted that three or more upper and lower stages may be provided. In this case, the swing table 51 is provided on all of the second and higher stages.
