Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial Application Field) The present invention relates to a loop-shaped main transport rail erected between roving and spinning processes, and a spinning machine base branched from the main transport rail. A roving bobbin is hung on a carrier mounted so as to be able to travel along a preliminary roving winding rail extending along and a branch rail such as a rail in the roving machine extending along the roving machine table, and the carrier is transported. The present invention relates to a transport rail in a roving transport system for transporting roving between roving and spinning processes.

(Prior art) In recent years, labor savings have been progressing in spinning factories, and one step has been advanced from automation in each process, and connection and transfer between each process have been automated. Automation of a roving bobbin has also been proposed. Generally, the roving wound on the roving bobbin is not completely consumed by the spinning machine, but is replaced with a new roving wound while remaining on the roving bobbin as a remaining roving of about one layer. Therefore, the roving bobbin after being used in the spinning machine must be supplied to the roving machine after treating the remaining roving. JP-A-62-110928 discloses that a main transport path 43 is provided along the outer periphery of a machine group of a spinning frame 41 and a roving frame 42 to suspend a large number of roving bobbins as shown in FIG. The main transport path 43, the spare roving winding rail 44 branched off from the main transport path 43, the roving machine inner rail 45, and a transport machine that pulls the transport body 47 that travels on the standby rail 46 and moves along the main transport path 43. 48, a bridge rail for connecting the main transport path 43 and the branch rails such as the rails 44, 45, 46, and a feed device that feeds into or out of the branch rail of the carrier 47 is provided. A roving yarn transport system has been proposed in which a roving yarn bobbin is transported between roving / spinning processes via a transport body 47 by a transporter 48 traveling round on a main transport path 43. At a position corresponding to the main transport path 43, a remaining roving process device for processing the remaining roving of the remaining roving bobbin suspended by the transporting body 47 unloaded from the preliminary roving winding rail 44 of the spinning machine. 49 are arranged.

(Problems to be Solved by the Invention) However, when the remaining roving process device 49 is disposed on the main transport path 43, another transporter cannot pass through the portion during the remaining roving process. There is a problem that the transfer efficiency of the entire transfer system is reduced.

On the other hand, the present applicant filed Japanese Patent Application No. 62-169515 with No. 8
As shown in FIGS. 9A to 9D, a rail 50 for processing remaining roving is provided which is branched from the main transport path 43 and has a length almost twice as long as the transport body 47. A device in which a remaining roving treatment device 49 is provided at a position, and a transport body feed device 51 is provided at a position where the distance from the branch to the main transport path 43 is shorter than the entire length of the transport body 47 is proposed. When the residual roving yarn processing rail 50 branches off from the main transport path 43 in this way, the residual roving processing operation by the residual roving processing apparatus 49 may hinder the transporter 48 traveling on the main transport path 43. There is no. However, in a state in which the transport body 47 is present in the residual roving yarn processing rail 50, while the residual roving bobbin suspended by the transport body 47 is undergoing the processing operation by the residual roving processing device 49, of course. However, even in the processing completion state or the carry-out standby state, it is not possible to newly carry the transport body 47 into the rail 50 for remaining roving yarn processing. Therefore,
When unloading the remaining roving bobbin from the preliminary roving winding rail 44 of the spinning machine 41, the transporting body 47, which suspends the remaining roving bobbin carried into the remaining roving yarn processing rail 50, processes the remaining roving. After the empty roaming machine has passed the position corresponding to the spare roving winding rail 44 after the completion of the transfer standby state after completion, the spare roving winding rail is
It is in a state in which the carrying body 47 can be unloaded from 44. For this reason, there is a problem in that there is much time loss before the remaining roving bobbins can be carried out from the spinning process, and the transport efficiency of the entire transport system is reduced.

Configuration of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, according to the present invention, a loop-shaped main transport rail provided between roving and spinning steps, and a branch from the main transport rail. The roving bobbin is hung on a carrier that is mounted so as to be able to travel along with a spare roving winding rail extending along the spinning machine table and a branch rail such as a roving machine inner rail extending along the roving machine table, In a roving yarn transport system for transporting the transported body by a transporter and transporting roving yarn between roving and spinning processes, a residual rail as a branch rail branched from a main transport rail between the spinning process and the roving process. A rail for yarn processing is provided, and the rail for processing residual roving is separately provided with a port for carrying in and a port for transporting out as a branch from the main transport rail. Is to the remaining roving treatment device installed on the rail. A standby state in which the transporting body hanging the empty bobbin after the residual roving process can be unloaded from the unloading port and does not hinder the loading of the transporting unit from the unloading port. And each of the branch rails is disposed so as to extend on the side opposite to the forward direction of the transporting machine at a branching point with the main transport rail, and the branch body is provided with a transport body in the forward direction of the transporting machine. When the transporter and the transporter move on the main transport rail in the forward direction of the transporter, they are always urged to the position that guides the transporter into the branch rail when moving to the opposite side. A permissible switching lever is provided.

(Operation) In the roving yarn transporting system having the transporting rail of the present invention, a transporting body on which a roving bobbin such as a full bobbin, a remaining roving bobbin, or an empty bobbin is suspended is pulled by a transporter to be a main transporter. While traveling on the rails, loading or unloading to or from the branch rails is performed by a transporter. The transporter from which the residual roving bobbin carried out of the spinning process is hung is carried into the residual roving processing rail from the transporter entrance. The residual roving bobbin suspended by the carrier conveyed into the residual roving yarn processing rail is guided to a standby section provided with an unloading port after completion of the residual roving process by the residual roving device. Wait in position. In this state, when the transporter suspending the residual roving bobbin unloaded from the spinning machine reaches the position corresponding to the residual roving yarn processing rail, the transporter moves from the loading port into the residual roving yarn processing rail. It is carried in. In the state where the remaining roving process of the remaining roving bobbin previously carried into the remaining roving yarn processing rail has not been completed, the transporting body that suspends the next remaining roving bobbin is moved to the remaining roving yarn processing rail. When the transport body reaches the position corresponding to, the transport body is guided to the standby unit after the residual roving processing of the transport body previously loaded into the residual roving processing rail, and the transport It is carried into the yarn processing rail from the carry-in port. On the other hand, the transport body guided to the standby section is carried out from the carry-out port and is carried to the roving process.
Therefore, regardless of the operation state of the remaining roving process, the transporting body with the remaining roving bobbin suspended from the spinning process can be carried out, and the transport efficiency of the entire transport system is improved.

Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, a main transport rail 3 is provided from the ceiling above the outer periphery of the first spinning frame and the second roving frame, and is arranged in a loop. A spare roving winding rail 4 is provided on both left and right sides of each spinning machine 1, and a roving inner rail 5 is provided above the front surface of the roving machine 2 as a branch rail branched from the main transport rail 3. In addition, spinning machine 1
The remaining roving yarn processing rail 6 is provided between the group and the roving machine 2 as a branch rail branched from the main transport rail 3. Each of the rails 3 to 6 is formed in a cross-sectional shape, and is a full bobbin doffed by the roving machine 2, a remaining roving bobbin after being used in the spinning machine 1, or an empty after the remaining roving process. A transport body 7 for suspending a roving bobbin such as a bobbin and transporting the roving bobbin between roving / spinning processes is provided so as to be able to travel on each rail. The transporting machine 8 which travels on the main transporting rail 3 by pulling the transporting body 7 is equipped with a connecting body 8a which can enter the rails 4, 5, 6 as the branch rails at the rear thereof. It is connected to the carrier 7 via 8a. In addition, when the transport body 7 and the connecting body 8a move to the opposite side to the forward direction of the transporter 8, the transport body 7 and the connecting body 8a are connected to the respective branches of the main transport rail 3 by the rails 4,5,6. When the transporter 8, the transporting body 7 and the connecting body 8a advance on the main transporting rail 3 (moving in the direction of the arrow in FIG. 1), they are always urged toward the position for guiding inward. A switching lever (not shown) configured to allow is provided.
That is, each of the branch rails is disposed so as to extend in a direction opposite to the forward direction of the transporter 8 at a branch portion with the main transport rail 3, and the branch portion has a simple configuration without using an actuator such as a cylinder. When the carrier 7 moves in the direction opposite to the forward direction of the transporter 8, the transporter 7 is guided into the branch rail, and the transporter 8 and the transporter 7 move on the main transport rail 3 in the forward direction of the transporter 8. When traveling to, it is allowed to pass through.

The residual roving yarn processing rail 6 is composed of a carry-in / work rail 6a having a length approximately twice as long as the transport body 7 and a carry-out / standby rail 6b as a waiting section branched from the rail 6a.
Each of the rails 6a and 6b is separately provided with a carrier carrying-in port 9 and a carrier carrying-out port 10 as branch portions connected to the main carrying rail 3. In the middle of the loading / working rail 6a, a residual roving processing device 11 of a known configuration is disposed, and on the loading / working rail 6a corresponding to the processing device 11, a branch from the main transport rail 3 is provided. The transporting device 12 is located at a position where the distance from the section is shorter than the total length 7 of the transporting body 7 and the connecting body 8a.
Are arranged. The carry-out / standby rail 6b is a carrier 7 that hangs the empty bobbin after the residual roving process by the residual roving device 11.
The remaining roving yarn processing device 11 is provided so as to be able to stand by without disturbing the loading of the carrier 7 from the loading port 9 and the processing of the remaining roving yarn by the remaining roving yarn processing device 11. A transfer body feed device 12 is disposed on the carry-in / work rail 6a and the carry-out / stand-by rail 6b which are branched from the carry-in / work rail 6a on the back side of the position.

Next, the operation of the device configured as described above will be described.
The transporter 8 moves on the main transport rail 3 in the direction of the arrow in FIG. 1 and transports from the roving process to the spinning process, from the spinning process to the remaining roving process, and from the remaining roving process to the roving process. Riding the body 7 or traveling alone. A transporter 8 that unloads a transporter 7 from which a remaining roving bobbin is suspended from a spare roving winding rail 4
As shown in FIG. 2 (a), the carriage 7 stops at the position where the rear end of the carrier 7 has passed through the carrier inlet 9 of the rail 6 for residual roving processing, and retreats from that position. As shown in (b), the transporting body 7 and the connecting body 8a are carried in / working rails 6a.
It is carried in. Then, after the connection between the connector 8a and the carrier 7 is disconnected by the operation of a connection disconnecting device (not shown), the remaining roving processing device 11 is operated, and as shown in FIG. Are sequentially moved to the inner side of the carry-in / work rail 6a by the action of the carrier feeding device 12, and the remaining roving process is performed. As shown in FIG. 2 (c), the transporter 8 is previously loaded into the residual roving yarn processing rail 6 to complete the residual roving process, and to unload the transporting body 7 waiting in the unloading / standby rail 6b. Then, the connecting member 8a is moved back to the position where it has passed through the carrier outlet 10 and then retreats in the same manner as described above to allow the connector 8a to enter the carry-out / standby rail 6b from the outlet 10. When the entry of the connecting body 8a is completed, the connecting body 8a is automatically connected to the connecting portion of the transport body 7 waiting in the unloading / standby rail 6b. Then, the transporter 8 advances again, pulls the transporter 7 suspended by the empty bobbin, and moves to the roving process.

On the other hand, as shown in FIG. 2 (d), the transport body 7 on which the residual roving has been processed by the operation of the residual roving yarn processing device 11 is transported by the transport body feeding device 12 provided at the back of the loading / working rail 6a. After the front end (the left end in FIG. 2 (d)) is moved to a position where it passes through a branching portion with the carry-out / standby rail 6b, the transfer provided on the carrier feeder 12 and the carry-out / standby rail 6b is performed. By the action of the body feeding device 12, as shown in FIG. 2 (e), it is fed into the unloading / standby rail 6b and waits until the next transporter 8 comes. When the transporter 8 pulls the transporter 7 from which the remaining roving bobbin is hung from the spinning process and reaches the rail 6 for processing the remaining roving, the residual coarse of the transporter 7 which has been loaded in earlier. In the case where the yarn processing is not completed and the state shown in FIGS. 2 (a) to 2 (c) is reached, the transporter 8 operates until the residual roving processing is completed before the loading port 9 of the residual roving processing rail 6. It waits and immediately carries out the work of loading the carrier 7 after the processing is completed. And then carry out
The transporter 7 on which the empty bobbin is suspended is carried out from the standby rail 6b.

In the above description, the transporter 8 freely travels on the main transport rail 3 to carry out and carry out, and in the case where there is a work request for carrying-in, the description has been made on the premise of the roving yarn carrying system for carrying-in or carrying-out work of the carrier 7. In the transport system, only one of the operations of loading or unloading the transporter 8 in each operation process such as the roving process, the spinning process, the remaining roving process, etc. separately proposed by the applicant of the present invention is always performed. There is a roving conveying system. Then, the operation status in each process when three transporters 8 are used is as shown in the diagram in FIG. 3 (a). That is, when the first machine carries out the unloading work in the roving process, the carry-in work is performed in the spinning process, and the unloading work is performed in the remaining roving process. The second machine running after the first machine performs the loading operation in the roving process, performs the unloading operation in the spinning process, and performs the loading operation in the remaining roving process. Also,
Unit 3 running after Unit 2 carries out unloading work in the roving process.
Carry-in work is performed in the spinning process, and carry-out work is performed in the remaining roving process. That is, each of the transporters 8 travels along the main transport rail 3 while alternately performing unloading and loading operations for each process. When the number of the transporters 8 traveling on the main transport rail 3 is three or an odd number as described above, there is no problem because the carry-out and carry-in operations in each process are performed alternately, but there is no problem in terms of the transport capacity and the like. When the number of the transporters 8 is four (or an even number), as shown in FIG. 3 (b), the type of work in each process of the fourth and first units is the same. There is no problem in performing the same work because a plurality of machines are arranged in the roving process and the spinning process. However, only one residual roving process device 11 is provided in the residual roving process. In such a case, if the remaining roving yarn processing rail 6 has the same configuration as that of the conventional apparatus, the operation of the system becomes impossible if a situation occurs in which the loading or unloading operation continues. However, in this apparatus, the carry-out / stand-by rail 6b is provided at a position where it does not hinder the carrying-in of the carrier 7 and the remaining roving processing work to the remaining roving processing rail 6, so that the loading or unloading work is performed. Is carried out, the transporter 8 can always perform the work. That is,
When the carrying-in work is continuous, the carrying machine 8 may carry out the carrying-in work after the previously carried-in carrier 7 is fed into the carry-out / stand-by rail 6b after the completion of the processing work by the remaining roving treatment device 11. In the case where the unloading operation is continuous, the transfer unit 7 that has just been loaded is subjected to the remaining roving process by the remaining roving process unit 11 and then fed into the unloading / standby rail 6b. 7 can be carried out.

Second Embodiment Next, a second embodiment will be described with reference to FIGS. 4 (a) to 4 (f). In this embodiment, the carry-out / standby rail 6b also serves as a work rail, and the carrier 7 is configured to be in the carry-out standby state when the remaining roving process by the remaining roving device 11 is completed. This is greatly different from the apparatus of the above embodiment. A remaining roving process device 11 and a carrier feeding device 12 are provided at an intermediate portion of the remaining roving process rail 6, and a portion behind the remaining roving process device 11 is formed as a loading / working rail 6a. The carry-in port 9 connected to the main transport rail 3 is branched. Further, a portion on the front side of the remaining roving process device 11 is formed as a carry-out / standby rail 6b, and a carry-out port 10 connected to the main carrying rail 3 is provided at the front end thereof. Therefore, in this embodiment, the transporter 8 which travels on the main transport rail 3 by pulling the transporter 7 on which the remaining roving bobbin is hung, as shown in FIG. Stops at the position where it has passed through the branch portion between the loading port 9 and the main transport rail 3, and then retreats, so that FIG. 4 (c).
The carrier 7 is carried into the carry-in / work rail 6a as shown in FIG. Then, after the connection between the transporting body 7 and the connecting body 8a is disconnected, as shown in FIG. 4 (d), it is previously carried into the remaining roving process rail 6 to complete the remaining roving process. Unloading port 10 for unloading the carrier 7 waiting in the unloading / standby rail 6b
To the position past. Next, as shown in FIG. 4 (e), the connector 8a is retracted to a position where it is connected to the carrier 7, and after the connection of the connector 8a and the carrier 7 is completed, the connector 8a moves forward and the bobbin is suspended. The transported body 7 is transported to the roving process. After the carrier 7 is carried out from the carry-out / standby rail 6b, the remaining roving treatment device 11 and the carrier feeder 12 are operated, and carried into the carry-in / work rail 6a as shown in FIG. 4 (f). The remaining roving process of the transported body 7 is started. Then, the transporter 8, which has pulled the transport body 7 during the remaining roving process and arrived at the remaining roving process, waits until the remaining roving process is completed as shown in FIG. Loading of the carrier 7 in the same manner as
The unloading work of the transport body 7 previously loaded is performed. That is, in the apparatus of this embodiment, unlike the previous embodiment, there is no need for the operation of transporting the transported body 7 on which the remaining roving process has been completed into the unloading / standby rail 6b by operating the transported body transporting device 12 again.

The present invention is not limited to the above-mentioned two embodiments. For example, as shown in FIG. 5, the branch point of the carry-out / stand-by rail 6b of the first embodiment from the carry-in / work rail 6a is processed by the remaining roving process. It may be configured to be the front side of the apparatus 11, or the residual roving yarn processing rail 6 may be formed in a loop shape as shown in FIG. In the case of such a configuration, it is possible to reduce the number of the transporter feeding devices 12 provided in the residual roving yarn processing rail 6. In addition, the remaining roving yarn processing rail 6 is formed in a loop shape, and the length from the remaining roving processing device 11 to the unloading port 10 is formed so as to be twice as long as the entire length of the transporting body 7.
May perform the remaining roving process during standby.

Advantageous Effects of Invention As described in detail above, according to the present invention, the carrying-in port and the carrying-out port are separately provided on the remaining roving yarn processing rail, and the carrying-in of the carrying body is hindered. A standby unit is provided to allow the transported body that has been previously loaded in a standby state, so that the transported body with the roving bobbin suspended from the spinning process is unrelated to the state of the remaining roving process. Therefore, there is an excellent effect that the operation efficiency of the remaining roving process device 11 and the transport efficiency of the entire transport system are improved. Also, the branch portions from the main transport rail of the branch rails such as the spare roving winding rail, the roving machine inner rail, and the remaining roving yarn processing rail are all of the same configuration and have a simple configuration that does not use an actuator. Since the transporting body can be guided into the branch rail when the transporting body retreats without hindering the traveling of the transporting machine and the transporting body that moves forward, even if there are a plurality of branching parts on the main transporting rail, the branching of a different configuration There is no need to prepare rails, and the manufacturing cost of the transport rails can be reduced.
