DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a package transport system for transporting a package processed by a draw false twisting machine or the like, and a package for a truck capable of efficiently transferring a package from a carrier of a ceiling transport truck to a peg truck. It relates to a transfer device.

[0002]

2. Description of the Related Art A conventional package transport system will be described by taking a draw false twisting machine as an example. Conventionally, as a package transfer system in a draw false twisting machine, the package of the main body is sequentially doffed by an automatic doffing device running between the primary heater and the main body, and is transferred to a rotary peg that circulates along the primary heater. 2. Description of the Related Art There is known a package transfer system in which a person transfers a package from an end of a rotary peg to a peg cart, stores the package in a state of being transferred to the peg cart, and sequentially inserts the package from the peg cart into a tray in an inspection process. Details of such a package transport system will be described below.

[0003] First, the overall configuration of a draw false twisting machine will be described.
In FIG. 7, a yarn 152 fed from a yarn supply package 151 in a creel stand 150 is held at a yarn tension that can be drawn by a first feed roller 153 and a second feed roller 154. On the downstream side between the two sets of feed rollers 153 and 154, a false twisting device 155 such as a nip twister is provided.
The yarn 152 upstream of 55 is in a twisted state. A primary heater 156 for heat fixing is provided on the upstream side between the two sets of feed rollers 153 and 154, and heats the twisted yarn 152 to a drawing temperature. Further, the third feed roller 1 is located downstream of the second feed roller 154.
57, and these two sets of feed rollers 154 and 154 are provided.
Between 157, a secondary heater 158 is provided to perform reheat treatment. The yarn 152 after the reheat treatment is finished into a package 160 by a take-up winder 159. In the above-described drawing false twisting machine, since the primary heater 156 is particularly tall, the primary heater 156 is separately arranged and opposed to the main body 161 after the false twisting device 155, and a passage 162 is provided therebetween. The doffing device 163 runs.

Next, a conventional package transport system in the above-described draw false twisting machine will be described. In FIG. 7, a rotary peg 164 that circulates around a primary heater 156 is installed as a package transfer device. Three pegs 165 project sideways from the rotary peg 164. The automatic doffing device 163 transfers the package 160 in the main body 161 to the peg 165,
The package 160 is held by the bobbin unit, picked up from the take-up winder 159, turned in the direction of 90 °, moved to a position facing the peg 165, and pushed out of the package 160 toward the peg 165. As shown in FIG. 8, a pusher device 169 is provided at an end of the rotary peg 164 so that three packages 160 can be sequentially transferred.

[0005] As shown in FIG.
There is a system for transferring a package to a peg trolley 166 as a package transfer means. The peg carriage 166 is formed by projecting three upper and lower pegs 167 in three rows, and is capable of traveling under control along the guide rail 168. That is, the peg cart 166 that has traveled to the position where the end peg 167 faces the pusher device 169 stops, and receives the transfer of the package 160 pushed out by the pusher device 169. Then, the peg cart 166 travels by the pitch P to make the next row of pegs 167 face the pusher device 169,
The package 160 is transferred. In this way, when the peg cart 166 is full, it travels as it is.

[0006]

The package formation by the above-described draw false twisting machine is performed in a 24-hour operation. This package is not dyed or shipped as is,
It is dyed or shipped after the inspection process. However, the inspection process is usually performed for 8 hours. Therefore, it is necessary to temporarily store the package from the drawing false twisting machine at a predetermined location. Therefore, the peg carts 166 described above are arranged and stored as they are. However, since the package transport system directly transfers the rotary pegs 164 to the peg carts 166, the number of packages that can be stored in one peg cart 166 is limited. A large number of peg carts 166 are required. This is because there is a restriction that the pegs 167 of the peg carriage 166 cannot be arranged in a staggered arrangement. Therefore, a system is conceivable in which the packages are transferred from the rotary pegs 164 to a carrier that has a plurality of rows of horizontal peg shafts that are hung from a ceiling carrier and the packages are transferred from the carriers to the peg cart. However, the direction in which a package can be transferred from a carrier having a plurality of rows of peg shafts to a peg cart is limited to one side of the peg cart, and transfer to a peg cart having pegs on both sides so that packages can be efficiently stored is easy. There is a problem that can not be.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to convert a carrier having a plurality of rows of peg shafts suspended from a ceiling carrier into a double-sided peg shaft. An object of the present invention is to provide an apparatus for transferring packages to a bogie that can efficiently transfer packages to a peg bogie having a peg shaft.

[0008]

In order to achieve the above object, the present invention provides an apparatus for transferring packages to a trolley, which is an apparatus for transferring packages to trolleys for transferring packages to pegs. A pusher device that holds the protruded carrier so as to be able to ascend and descend in a suspended state from a ceiling transport vehicle and selectively pushes out a package, and a peg cart having pegs on both sides is placed at a position facing the pusher device and 180 And a reversible turntable.

[0009]

When the peg cart facing the pusher device capable of holding the carrier so as to be able to move up and down is inverted, the packages are transferred to both sides of the peg cart using the positions of the pusher device and the carrier as they are.

[0010]

Stops. Then, the pusher 61 is advanced by the pusher 60, hits the bobbin portion of the package inserted into the peg 14, and pushes the package toward the peg 54. The vertical arrangement pitch of the pegs 14 of the carrier 6 is P1, which coincides with the vertical arrangement pitch P1 of the pegs 165 of the rotary peg 164 in FIG. However, the pegs 54 of the peg cart 7 should be able to store packages as densely as possible.
The vertical arrangement pitch P2 is smaller than P1. Therefore, the upper and lower three packages cannot be transferred at the same time, and the packages are transferred after the carrier 6 is lowered by P1-P2.

Further, referring to FIG. 6, the procedure for transferring the package will be described. First, the peg cart 7 is placed on the swivel carrier 31. Then, the guide 16 of the carrier 6 is fitted to the two guide bars 62 on the left side, and is held so as to be able to move up and down. The carrier 6 is lowered until the peg with the circle symbol 1 of the peg cart and the package with the circle symbol 1 on the carrier 6 face each other, and the package with the circle symbol 1 is transferred. The carrier 6 is lowered by an amount corresponding to P1-P2, and the package with the circle symbol 2 is transferred to the peg with the circle symbol 2. Similarly, the package with the circle 3 is transferred to the peg with the circle 3. Next, the package with the circle code 4 is the circle code 4
The carrier 6 rises to face the peg of
Package is transferred. The carrier 6 is lowered by P1-P2, and packages 5 and 6 are transferred. Next, the carrier 6 is lowered so that the package of the circle 7 faces the peg of the circle 7, and the package of the circle 7 is transferred. The carrier 6 is lowered by P1-P2, and the packages indicated by circles 8 and 9 are transferred.
Becomes empty.

Next, the carrier 6 full of packages is fitted into the two guide rods 62 at the center and held up and down freely. Then, in the same procedure as described above, the packages with circles 10 to 18 are transferred to the pegs with circles 10 to 18, and the carrier 6 becomes empty. Further, the carrier 6 loaded with the package is fitted into the two right guide bars 62 and is held so as to be able to move up and down. Then, in a similar procedure, the package with the circle symbol 22 to the circle symbol 27 is transferred to the peg with the circle symbol 22 to the circle symbol 27, and one side of the peg cart 7 is fully loaded. Then, the swivel carrier 31 is swiveled 180 ° as indicated by arrow 70, and the packages are fully loaded on the other one side in the same manner as described above, and a total of 54 packages are stored on both sides. Then, the turning conveyance table 31 is indicated by an arrow 71.
After turning 180 ° in the opposite direction and returning to the original state, the chain 36 travels about half a turn, and the fully loaded peg cart 7 is conveyed on the right carrier 32 in the forward direction.
At the same time, the empty peg cart 7 is sequentially fed from the left carrier 32 onto the revolving carrier 31. The packages are sequentially stored in the peg cart 7 by repeating the above procedure.

Returning to FIG. 1, 54 packages can be stored in the peg cart 7, and the draw false twister 1 normally processes 216 packages at a time. One single package can be stored. That is, when the number of peg carts 7 is set to a predetermined number, packages processed during nighttime operation can be efficiently stored. The peg cart 7 full of packages is automatically or manually conveyed to the inspection / packing process, and the packages of the peg cart 7 are sequentially inserted into the tray and conveyed to the inspection process. By the way, the transfer of the package from the rotary peg 164 to the carrier 6 by the carrier moving device 2 is performed in a short time. Further, the package can be efficiently transferred to the peg cart 7 which can store the packages on both sides by the reversing structure of the revolving transfer table 31 of the package transfer device 3 to the cart. Therefore, this package transport system is excellent in transport efficiency, and is a transport system capable of coping with a large number of draw false twisting machines by minimizing the number of ceiling transport vehicles 5 installed.

The above-described apparatus for transferring a package to a carriage can be applied not only to a package transfer system of a draw false twisting machine but also to a package transfer system of another synthetic fiber processing machine.

[0027]

According to the present invention, there is provided a package transfer device for a truck, which comprises a pusher device for holding a carrier having a lateral peg projecting therefrom so as to be able to ascend and descend from a ceiling carrier and selectively pushing out a package. A peg cart having a peg is placed at a position facing the pusher device and has a swivel base that can be turned 180 ° and when the peg cart facing the pusher device is turned over,
Since the packages are transferred to both sides of the peg cart using the positions of the pusher device and the carrier as they are, the packages can be efficiently transferred to the peg cart having the pegs on both sides with a simple device configuration.
