[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device provided in a false twisting machine or the like.

[0002]

2. Description of the Related Art Conventionally, in order to convey a package produced by a false twisting machine, an automatic doffing device is provided in a passage between a main body side having a winding device and the yarn feeding side having a primary heater. , The package was fully transferred to a peg stand installed so as to face the winding device, and then the operator carried out the package with a hand truck to be used for the inspection process and the like. .

[0003]

However, such a conventional transport system is inefficient and imposes a heavy burden on the operator. For this reason, a system has been proposed in which a package is automatically transported by using a transport device or the like (JP-A-3-102077, JP-A-4-3135).
No. 67), a yarn cooling unit is installed above a passage that serves as a package delivery point, and therefore, there remains a problem that the transport path and the drive mechanism are complicated in order to avoid this.

Therefore, in view of the above circumstances, the present invention was devised to provide a transporting device having a simple structure that can automatically transport an object to be transported even if there is a space limitation at a point where the object is transported.

[0005]

SUMMARY OF THE INVENTION The present invention is provided at a transfer medium that travels along a ceiling transfer path and is formed so as to be dividable in the direction of travel, and at a delivery location of an object to be transferred that is transferred by the transfer medium. It is provided with an elevating mechanism for elevating the division unit of the conveyance medium between the ceiling conveyance path and a predetermined loading / unloading section. It is preferable that the carrier medium has a connecting means for engaging and disengaging the split units by lifting and lowering. It is preferable that the ceiling conveying path is provided with traveling drive means for traveling the conveying medium at predetermined intervals.

[0006]

With the above structure, when the carrier medium travels along the ceiling carrier path and reaches the position above the carry-in / carry-out section, the carrier mechanism lowers to the level of the transfer place to carry in / out the object to be carried. The coupling means is in a coupled state while the transport medium is running, and separates the split unit when the transport mechanism is moved up and down by the elevating mechanism. The traveling drive means sequentially operates when the transport medium is engaged and causes the transport medium to travel along the ceiling transport path.

Next, the operation of this embodiment will be described.

When carrying a package P of a full tube produced by the false twisting machine 1, first, an empty paper tube is inserted into each peg 16 of the peg stand 3 at the empty paper tube supply station, and the peg stand 3 is run. The driving means 30 runs along the guide rail 29 to the target false twisting machine 1. When the head of the peg stand 3 arrives at the position of the control end 15 and enters the rail 52 of the elevating mechanism 4, the traveling is stopped and the elevating motor 51 is driven to feed the steel belt 53, and the rail 52 is lowered. Let By this lowering, the leading division unit 3a is separated from the remaining peg stands 3, and only the division unit 3a is lowered to the position of the peg stand holding mechanism 56. Split unit 3
The middle and lower horizontal frames 19 and 20 of a are the guide frames 5.
When the level becomes substantially equal to 7, 58, the lifting motor 51 is stopped and the horizontal moving means 70 and the horizontal moving motor 60 are driven. With this, the split unit 3a is moved from the rail 52 to the guide frames 57 and 58, and thereafter, the split unit 3 that has become the head as the peg stand 3 travels.
a is sequentially lowered by the elevating mechanism 4 and is re-connected to be sequentially fed along the guide frames 57 and 58, so that the entire peg stand 3 is installed so as to face the winder 9. When this installation is completed, the automatic doffing device is run in the passage 10 to replace the paper tube of the peg stand 3 with the package P of the winding weight which is full.

When all of the packages P are hooked on the pegs 16 of the peg stand 3 by the doffing by the automatic doffing device, the peg stand 3 is controlled along the guide frames 57 and 58 by the operation opposite to the loading operation. While horizontally moving in the direction of the end 15, the leading division unit 3a is moved up and down by the lifting mechanism 4
Then, it is sequentially lifted up to the ceiling transport path 2 to be reconnected, and is moved along the ceiling transport path 2 by the traveling drive means 30 to be carried into the package storage station.

In this way, the peg stand 3 provided with the pegs 16 is divided in the traveling direction A, and the ceiling conveying path 2 and the elevating mechanism 4 sequentially carry in / out the divided units 3a at the position of the control end 15. Therefore, automation of package transportation in the false twisting machine 1 without contacting the balloon control plate 12 is achieved. Further, the ceiling transfer path 2 is a simple path, and the elevating mechanism 4 may be small in size, which contributes to space saving. Further, the peg stand 3 is installed only when necessary, does not occupy the passage 10 except when doffing, and does not hinder the passage of an operator or an automatic doffing device. Further, since the dividing units 3a are connected to each other by the connecting means 21 that engages and disengages by raising and lowering, the raising and lowering movement and the horizontal movement can be performed smoothly, which contributes to speeding up the transportation. Since the traveling drive means 30 are arranged on the ceiling transfer path 2 at a predetermined interval, even the long peg stand 3 can be transferred at a relatively low cost. That is, as shown in FIG. 7, the traveling drive means 30 may be provided at intervals l slightly shorter than the total length L of the peg stand 3 (L <l), and the peg stand 3 can be operated by sequentially driving these. You can drive to the position you want.

Although only one false twisting machine 1 is illustrated in FIG. 2, the automatic transfer of the package P can be performed by adding the ceiling transfer path 2 and the like appropriately even in a factory where many machine stands are arranged in parallel. It can be carried out. Further, as a progressive mechanism for installing the peg stand 3, various conceivable examples are not limited to the illustrated example,
For example, the split unit 3a of the peg stand 3 may be moved by pushing the cylinder. Furthermore, although the case where the present invention is applied to the false twisting machine 1 is shown, the carrying device of the present invention can naturally be applied to other textile machines and the like, and the object to be carried is not limited to the package P. The installation location of the lifting mechanism 4 should be set depending on the circumstances of the delivery place of the transported object, and is not limited to the end of the delivery place.
