Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial Application Field) The present invention relates to a main conveyance path erected between roving and spinning processes.
A roving bobbin is suspended from a rotatable bobbin mounted on a rotatable machine such as an inner roving rail, a preliminary roving winding rail, and a remaining roving yarn processing rail, which is branched from the main transport path. And a roving yarn transport system for transporting roving yarn between roving and spinning processes by pulling the roving yarn with a transporter.

(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. For example, in Japanese Patent Application Laid-Open No. 61-194228, as shown in FIG. 5, a main transport path 43 is provided along the outer periphery of a group of spinning machines 41 and roving machines 42 to suspend a large number of roving bobbins. Lower main transport path 4
3.A transporter 48 that moves along the main transport path 43 by pulling the transport body 47 that travels on the preliminary roving winding rail 44, the roving machine inner rail 45, and the standby rail 46 that are branched from the main transport path 43.
In addition, a bridge device that connects the main transport path 43 and branch rails such as the rails 44, 45, and 46 and a feed device that feeds the transport body 47 into or out of the branch rail 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.

(Problems to be Solved by the Invention) Although the above publication does not specifically refer to the operation control method of the transporter 48, a plurality of automatic machines (in this case, the transporter 48) generally run on the main transport path 43. When performing the work while traveling round, the transport machine 48 is set to free travel, and a work request signal (a carry-in request signal for the carrier 47 or a carry-out request signal for the carrier 47) is issued from the spinning machine 41, the roving machine 42, or the like. If the request signal is provided, the operation is stopped at a position corresponding to the spinning frame 41 or the roving frame 42 in which the request signal is present, and loading or unloading of the carrier is performed. However, when the work is stopped at the position only when there is a work request signal in such a free running and the work is performed, if the traveling interval of the plurality of portable machines 48 is shortened, Is carried out in accordance with the work request signal from the spinning frame 41 or the roving frame 42, and carries out the loading operation sequentially, and the transporting machine 48 moving from the rear stands by at the rear during the operation of the front transporting machine,
When the machine in front of the vehicle starts traveling, a situation occurs in which the vehicle only starts traveling at regular intervals and does not perform any work.
There is an inconvenience that the work efficiency of the transporter decreases and the roving yarn transporting ability of the entire transport system also decreases.

In the transport system in which the transporter travels freely, there is no problem when the transport interval between the transporters from the roving machine is long. However, inconvenience occurs when the number of roving machines is increased and the transport interval is shortened. That is, the transfer capacity of this transfer system is represented by the minimum interval at which the transfer body 47 can be unloaded from the spinning frame 41 or the roving frame 42, and the minimum transfer interval by the transfer frame 48 is provided to prevent collision between the transfer frames. This is the sum of the time required to travel the closest minimum distance and the work time in the work zone. For example, if it is necessary to unload every 5 minutes, the time required to travel the minimum distance between the transporters 48 is 1.
If the work time is 5 minutes and the work time is 3 minutes, the total time of both is 4.5 minutes, and the spare time for the smooth operation of the transport system is 0.5 minutes. However, when the transporter 48 is running freely In this case, the transmission of the work request signal and the timing of passing the work machine 48 through the work zone are shifted, so that the work machine 48 travels to the next work zone without performing work in the work zone. When such a situation occurs, the minimum transport interval by the transporter requires an additional travel time of at least 1.5 minutes in order to prevent collision between the transporters in addition to the above 4.5 minutes, and the total time becomes 6 minutes or more, and the minimum transport interval is 5 minutes. There is a problem that the operation of the transfer system that requires transfer every minute becomes impossible, and the transfer capability is reduced.

Configuration of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, a main transport path erected between roving / spinning processes, and a roving machine branched from the main transport path A roving bobbin is hung on a carrier guided along a branch rail such as a rail, a preliminary roving winding rail, and a remaining roving yarn processing rail, and a plurality of transporters are arranged so as to be able to travel along a main transport path. Then, in a roving yarn transporting system that transports the transporting body by each transporter and transports the roving between the roving / spinning processes, each transporter includes a roving process, a spinning process, a remaining roving process, and the like. When passing through each process, each of the transporters always performs only one of the operations of loading the transport body into the branch rail provided in each process and transporting the transport body from the branch rail.

(Operation) In the present invention, a transporter traveling along a main transport path provided between roving and spinning processes transports a transported body on which a roving bobbin such as a full bobbin or an empty bobbin is hung, and rovings.・ Convey roving between spinning processes. The transporter moves in the order of roving process, spinning process, remaining roving process, and roving process, and when passing through each process, be sure to make a branch rail such as a rail in the roving machine, a spare roving winding rail, and a rail for remaining roving process. Only one of the work of loading and unloading the carrier into and out of the work is always performed. Therefore, even if the work request signal is issued in each process, the transporter does not pass through the process without performing the work, and the transport efficiency is increased.

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 path 3 forming a closed loop is erected from the ceiling around the roving frame 1 group and the spinning frame 2 group, and a rail 4 in the roving frame as a branch rail is provided above the front surface of the roving frame 1. A spare roving winding rail 5 as a branch rail is disposed on each of the left and right sides of the spinning machine 2. In addition, between the spinning step and the roving step, the remaining roving yarn processing rail 6 as a branch rail constituting the remaining roving processing step.
Are arranged in parallel. The main transport path 3 is disclosed in
No. 194228, a support rail configured similarly to the conventional apparatus disclosed in Japanese Patent Application Laid-Open No. 194228 and having a pulling unit 7a and a bridge rail mounting unit 7b running in a suspended state, and a transporting body supported below the support rail. It consists of rails. The carrier traveling rail is divided at a position corresponding to each of the rails 4, 5, and 6, and at the divided portion of the traveling rail, main transport path connecting rails are pivotally disposed at a connection position and a retracted position, respectively. It is arranged as possible. Then, the transporter 7 pulls the chain-shaped transporting body 8 on which a large number of roving bobbins are hung, or travels on the main transporting path 3 only by the transporter 7, and the rails 4, 5, 6. And stops at that position, places a bridge rail (not shown) mounted on the bridge rail mounting portion 7b at the connection position, and drives a carrier driving device (not shown) to drive each rail 4 , 5,6 to carrier 8
, Or the carrier 8 is fed. The end of each of the rails 4, 5, and 6 on the carrying-in side is provided with a connecting / disconnecting device similar to the connecting / disconnecting device disclosed in Japanese Patent Laid-Open No. 62-110928 in order to disconnect the connecting between the carrying machine 7 and the carrying body 8. The connection and disconnection device 9 having the configuration is provided respectively. Also, approximately 2
At a middle portion of the remaining roving yarn processing rail 6 having a double length, a remaining roving yarn processing device 10 having a known configuration is disposed, and the remaining roving yarn processing rail 6 corresponding to the processing device 10 is provided. On the upper side, a carrier feeding device 11 is disposed at a position where the distance from the branch to the main transport path 3 is shorter than the entire length of the carrier 8.

The position of the main transport path 3 facing the transporting machine travel path is at a position facing the entrance of the rail 4 in the roving machine, the preliminary roving winding rail 5, and the rail 6 for the remaining roving yarn treatment. Work request lamps 12, 13, and 14 for indicating whether a carry-in or carry-out operation is required are provided, respectively.
In the main transport path 3, work notification lights 15, 16, 17 are provided as means for informing the transporter whether or not there is a request for loading and unloading of the transport body 8 in the roving process, the spinning process, and the remaining roving process. Each is disposed at the entrance of each process. The work request light 12
And the operation notification lights 15 to 17 are input to the control device C to which the status of each process, that is, the operation status and the like in each of the roving rails 4, the preliminary roving winding rail 5, and the remaining roving yarn processing rail 6, is input. Based on the data, it is turned on or off by a command from the control device C. The work notification lamps 15, 16, and 17 also indicate the type of work to be carried in and carried out, and there is a request for the carry-in or carry-out work of the carrier 8 in each step by the photoelectric tube provided in the traction unit 7a. It is determined whether or not a work request signal suitable for the state of the transporter 7 has been detected before entering the process.

Next, the operation of the device configured as described above will be described.
In the roving process, when the operation of each roving machine 1 is continued and the full bobbin stops, and then the full bobbin is suspended on the transporting body 8 loaded into the rail 4 in the roving frame, a signal indicating that the transporting body 8 can be unloaded is issued. After the carrier 8 has been carried out, a carrier carrying enable signal is output to the control device C. In the spinning process, the remaining roving bobbin suspended by the creel of the spinning machine 2 and used after the roving is used, and the full bobbin suspended by the carrier 8 loaded into the preliminary roving winding rail 5 When the replacement operation is completed, a transportable carry-out signal from the preliminary roving winding rail 5 is output to the controller C when the transporter 8 is completely unloaded. Further, in the remaining roving process, the transporter carrying enable signal is sent to the transporter loaded into the remaining roving process rail 6 in a state where the transporter 8 is not loaded into each of the remaining roving process rails 6. When the processing of the suspended remaining roving bobbins is completed and the transport body 8 is disposed at the loading-side end, an unloadable signal is output to the control device C. The control device C receives the output signal from each of the processes and, when a plurality of the same work request signals are output from each of the processes, determines a priority in consideration of the operation status of the machine and the like, and determines the priority in accordance with the priority. The work request lights 12, 13, 14 provided at positions corresponding to the loading side ends of the rails 4, 5, 6 are turned on, and the work notification lights 15, 16, 17 provided at the entrance of each process. Lights up. The transporter 7 traveling on the main transport path 3 stops at the position corresponding to the work notification lights 15, 16, 17 provided at the entrance of each process, and turns on the lighting states of the notification lights 15, 16, 17. Detected by photoelectric tube
, That is, whether or not there is a work request signal corresponding to whether or not the transport body 8 is towed, and then enters the process, and the rails 4, 5, 6 on which the work request lights 12, 13, 14 are lit. To stop or carry-in or carry-out work of the carrier 8 to the rail.

The operation status in each process when three transporters 7 are used is as shown in the diagram in FIG. 2 (a). That is, when the first machine performs the loading operation in the roving process, the unloading operation is performed in the spinning process, and the loading operation is performed in the remaining roving process. The second machine running after the first machine performs an unloading operation in the roving process, performs a loading operation in the spinning process, and performs an unloading operation in the remaining roving process. In this case, when the second unit unloads the carrier 8 from the remaining roving process, the first unit is placed in a rail 6 for remaining roving that is different from the rail 6 for remaining roving that the first unit has carried in the carrier. Unloading of the transporting body 8 in a standby state is performed. Then, the No. 3 machine carries out 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. That is, each transporter 7 travels along the main transport path 3 while performing loading and unloading operations alternately for each process. If the number of the transporters 7 traveling on the main transport path 3 is three or an odd number, the loading and unloading operations in each process are performed alternately, so there is no problem. When the number of units is four (or an even number), the type of work in each process of the fourth unit and the first unit is the same as shown in FIG. 2 (b). Since the roving process and the spinning process are provided with a plurality of machines, there is no problem in performing the same operation. However, when only one rail for the remaining roving process is provided, the remaining roving process is performed. The unloading work will be continuous in the process. That is, when only one residual roving yarn melting rail 6 is provided, the operation of the system becomes impossible. However, in this embodiment, since two residual roving yarn processing rails 6 are provided,
Regardless of whether the number of transporters is odd or even, each transporter 7
Can travel on the main transport path 3 while always performing only one of the unloading and loading operations in each process.

Second Embodiment Next, a second embodiment will be described with reference to FIGS. In this embodiment, the rail 4 in the roving machine, the preliminary roving winding rail 5 and the remaining roving treatment rail 6 are always connected to the main transporting path 3 respectively. A switching point (not shown) is provided, and the transporter 7 is not equipped with a bridge rail mounting portion;
At the rear of the transporter 7, there is provided a connecting body 18 that can enter the branch rail, and the transporting body 8 is connected to the connecting body 18, and the transporting body 8 is transported to each of the rails 4, 5, and 6. The difference is that it is performed from the back side. At the point provided at each of the branch portions, the transporting body 8 and the connecting body 18 are guided into the respective rails 4, 5, and 6 when the transporting body 8 and the connecting body 18 move in the direction opposite to the arrow in FIG. And the transporter 7, the transporter 8, and the connector 18 are allowed to pass through the main transport path 3 when moving in the direction of the arrow. Therefore, in the apparatus of this embodiment, as shown in FIG. 4 (a), the transporter 7 is connected to a branch rail that requires loading of the transporting body 8, for example, the remaining roving yarn processing rail 6 and the main transporting path 3. It stops at the position where the rearmost part of the transport body 8 has passed the point provided at the branch portion. Next, the transporter 7 is connected
Retreats to a position where it enters the branch rail. In this state, the connecting portion between the transporting body 8 and the connecting body 18 is in a state corresponding to the connection releasing device 19, and the connecting releasing device 19 is operated to separate the transporting body 8 from the connecting body 18. Next, the transporting machine 7 moves to the next step in an empty state. Also, from inside the branch rail, the carrier 8
As shown in FIG. 4 (c), the transporter 7 stops at a position where the connecting body 18 has passed the point of the rail, and then moves backward, so that the connecting body 18 enters the branch rail. The connecting portion provided at the rear portion is automatically connected to the connecting portion of the transport body 8. Therefore, the transporting body 8 is carried out by moving forward in that state.

Note that the present invention is not limited to the above-mentioned two embodiments. For example, the number of the remaining roving yarn processing rails 6 may be other than two, or the work request lights 12, 13, 14 and the work notification lights 15, 16 may be used. , 17
Is turned on for each process directly on the basis of the carry-in or carry-out enable signal output from each process, or the transport body 8 with a full bobbin suspended between the roving process and the spinning process is temporarily stopped. It is also possible to provide a standby rail for temporarily stocking, and a standby rail for temporarily stocking the carrier 8 with an empty bobbin suspended between the remaining roving process and the roving process. Good.

Effects of the Invention As described in detail above, according to the present invention, in each step of the roving process, the spinning process, etc., the transporter always performs one of the operations of loading and unloading the transport body, and then moves to the next process. Therefore, the transmission of the work request signal in each process does not coincide with the passing timing of the transporter and the transporter, and the transporter passes through the transporter without performing any work of loading or unloading the transporter in the process. In addition to preventing the lowering, each transporter performs the loading and unloading operations alternately in each step, thereby providing an excellent effect that the control is facilitated.
