Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial Application Field) The present invention relates to a main transport rail installed between roving and spinning processes, a rail in a roving machine branched from the main transport rail, and a preliminary roving winding rail. , A roving bobbin is hung on a transporter equipped so as to be able to travel along a branch rail such as a residual roving process rail, and the transporter is transported by a transporter, and the roving yarn is fed between the roving and spinning processes. The present invention relates to a roving yarn conveying system for conveying.

(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, Japanese Patent Application Laid-Open Nos. 50-76340 and 51-23331 disclose that a pallet on which a roving bobbin is suspended is boosted by a battery car, and the full bobbin doffed in the roving process is refined. A method is disclosed in which an empty bobbin after being used in a spinning step is transported to a roving step. Also, JP-A-61-19
As shown in FIG. 8, in Japanese Patent No. 4228, 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, and a large number of roving bobbins are suspended to form a main transport path 43. The main transport is performed by a transporter 48 that travels along the main transport path 43 by pulling the transport body 47 traveling on the preliminary roving winding rail 44, the roving machine inner rail 45, and the standby rail 46 branched from the main transport path 43. Road 43 and each of the rails 4
4, 45, 46 and the like are provided with a bridge rail for connecting the branch rail and a feed device for feeding the carrier 47 into or out of the branch rail, and circulate on the main transport path 43. A roving yarn transport system has been proposed in which a roving yarn bobbin is transported between roving and spinning steps by a transporter 48 via a transport body 47. In this transport system,
The main transport path 43 is divided at a position corresponding to each branch rail, and the main transport path connection rail is rotatably disposed at the connection position and the retracted position. Stop at the position corresponding to the branch rail that requires loading or unloading, connect the main transport path 43 and the branch rail by the bridge rail provided to the transporter 48, and drive the transport body feeding device. The carrying-in or carrying-out work of the carrier 47 is performed.

(Problems to be Solved by the Invention) However, in the former method, since the battery car is simply pushed on the pallet and moves on the rail, the loading of the pallet into the rail corresponding to the roving machine or the spinning machine is difficult. Although it is possible, the work of unloading the pallet from the rails cannot be performed, and there is a disadvantage that the unloading work must be performed manually or using other devices.

On the other hand, in the latter transport system, the transporter 48 has a built-in bridge rail, a driving device therefor, a transporter transporter, and the like, so that the transporter 48 is large and heavy. For this reason, the main transport path connecting rail is rotatably disposed at a position corresponding to each branch on the rail on which the transport body 47 travels, and separately from the rail on which the transport body 47 travels. A dedicated rail for transporter 48 was required.
In addition, the main transport path by the bridge rail mounted on the transporter 48
Carrier for positioning, etc. when connecting 43 to each branch rail
There is also a problem that high-precision positioning is required when the 48 stops.

Configuration of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, a main transport rail erected between the roving / spinning processes and a roving machine branched from the main transport rail are provided. A roving bobbin is hung on a transporter equipped to be able to travel along a branch rail such as a rail, a preliminary roving winding rail, a residual roving process rail, and the transporter is transported by a transporter to roving / spinning. In a roving yarn transport system that transports roving yarn between spinning processes, the transporter has a connecting portion that can be brought into contact with and separated from the transporting body on the rear side, and a linking member that can enter and bend into the branch rail is integrated. The transfer of the transport body to the branch rail and the transport of the transport body from the branch rail are performed by retreating and moving forward on the main transport rail of the transporter in a connected state with the transport body.

(Operation) In the present invention, the transporter moves on the main transport rail integrally with the transporter connected via the detachable connecting portion to transport the roving between the roving / spinning processes. Rover rail,
When a transport body is loaded into a branch rail such as a spare roving winding rail, the state of the branch portion of the branch rail with the main transport rail allows the transport body to enter the branch rail from the main transport rail, and It is pushed by the transporter and is loaded into the branch rail. After the carrier is loaded into the branch rail, the connection of the transporter with the transporter is disconnected, and the transporter moves along the main transport rail to a position where the transporter needs to be unloaded. Also, when the carrier is unloaded, the connection with the carrier enters the branch rail, and after the connection with the carrier is completed, the transporter is moved forward by the transporter, and the carrier is pulled by the transporter and moved into the branch rail. It is carried out from. The transporter is connected to the carrier via a bendable connector integrally connected to the rear side of the transporter. Since the connector can enter the branch rail, the transporter does not enter the branch rail. By retreating and moving forward on the transfer rail, the transfer of the transfer body to the branch rail and the transfer of the transfer body from the branch rail are performed.

(Embodiments) The present invention is embodied as follows.
Description will be made with reference to the drawings. As shown in FIG. 1, a main transport rail 3 is erected from the ceiling above the outer peripheries of the first spinning frame group and the second roving frame group, and preliminary roving winding rails 4 are provided on both the left and right sides of each spinning frame. In the upper part of the front side of the figure, rails 5 in the roving machine are arranged as branch rails branched from the main transport rails 3 respectively. Further, a remaining roving yarn processing rail 6 is provided between the main spinning frame 1 and the roving frame 2 group, and a remaining roving processing device 7 is provided at an intermediate portion of the rail 6. Has been established. Each of the rails 3, 4, 5, and 6 is a cross section. The transport body 8 is provided so as to be able to travel on each rail, and the transporter 9 is equipped so as to be able to travel along the main transport rail 3. As shown in FIG. 3, the transporting body 8 has rollers 10 on both sides on which the rollers 10 roll, and an engaging roller 11 on the upper surface, which is rotatably mounted, and one bobbin hanger 12 on the lower surface.
Are connected by links 14, and a hook 15 is provided at the front end of the carrier 8. Further, as shown in FIG. 2, the mechanism 9 for pulling the transport body 8 and traveling on the main transport rail 3
Two sets of rollers 16 rolling on the upper side are provided on both sides, and an engaging roller 17 is supported on the main transport rail 3 via two supports 18 rotatably mounted on the upper surface in a suspended state,
In the middle of both supports 18, the drive wheels 19 abut on the lower surface of the main transport rail 3 to run on the main transport rail 3 by rotational driving. Further, the transporter 9 is integrally connected to a chain-shaped, ie, bendable connecting body 20 equipped with an engaging roller 20a at a rear portion thereof, and a hook as a connecting portion provided at a rear end of the connecting body 20. The carrier 15 is connected to the carrier 8 by hooking the hook 15 of the carrier 8 on the stop pin 20b. The support 18 is connected by a link 21. Further, the transporter 9 has a sensor for detecting a stop position at the time of loading and unloading of the transport body 8 to and from the rails 4, 5, and 6, and a sensor for detecting a rail that requires loading and unloading ( (Both are not shown).

A travel path switching device 22 is provided at a branch between the main transport rail 3 and each of the rails 4, 5, and 6, respectively. As shown in FIGS. 4 and 5, the fork rail 23 provided at the branch portion
The rail body supporting the 0, 16 is fixed at a predetermined position. A lever 24 constituting the travel path switching device 22 is rotatably supported by a support shaft 26 fixed to a support plate 25 near its base end. The lever 24 is disposed inside the fork rail 23 so as to be reciprocally rotatable between an entry preventing position for preventing the transport body 8 from entering the branch rail and an entry allowing position for allowing the entry. A tension spring 29 is stretched between a latching pin 27 protruding from the base end and a latching pin 28 protruding from the support plate 25, and is urged toward the approach allowable position shown by a chain line in FIG. Is held. The lever 24 is engaged with each of the engagement rollers 11, 17 and the like in a state where the lever 24 is arranged at a position where the carriage 8 and the like are allowed to pass on the main conveyance rail 3 as shown by solid lines in FIG. The mating portion is formed so as to be linear and have a length that can simultaneously engage with the two engagement rollers 11, 17 and the like.

Next, the operation of the device configured as described above will be described.
The mechanism 9 moves on the main transport rail 3 in a predetermined direction as shown in FIG. 1 and moves 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. The transporting body 8 is towed or travels only by the transporter 9. The traveling path switching device 22 provided at each branching section is provided by a tensioning spring 29, which always moves the transporter 9, the connecting body 20 and the transporting body 8 traveling on the main transporting rail 3 as shown by a chain line in FIG. It is held so as to cross the passing position of the engagement rollers 17, 20a, 11. In this state, when the transporter 9 moves forward, that is, travels on the main transport rail 3 to the left in FIG. 4, the engagement roller 17 provided at the foremost portion first engages with the outer portion of the lever 24. , The lever 24 is moved on the main transport rail 3 while rotating the lever 24 counterclockwise in FIG. 4 against the elastic force of the tension spring 29 with the movement of the transporter 9. When the lever 24 is located at the position shown by the solid line in FIG. 4 and before the engagement between the frontmost engagement roller 17 and the lever 24 is released, the connecting body 20 and the transport
Of the engaging rollers 20a, 11
It moves on the main transport rail 3 in a state where the pieces are engaged. Accordingly, once the lever 24 is disposed at the position shown by the solid line in FIG. 4, the lever 24 is held at the same position until the engagement with the engagement roller 11 at the rearmost portion of the transport body 8 is released. When the engagement between the engagement roller and the lever 24 is released, the lever 24 is rotated clockwise in FIG. The rotation is restricted at the contact position, and the carriage 8 is maintained in a state of allowing the transport body 8 to enter the branch rail indicated by a chain line in FIG.

Next, a case where the carrier 8 is carried into a branch rail, for example, the rail 5 in the roving machine will be described with reference to FIGS. 6 (a) to 6 (e). As shown in FIG. 6 (a), the transporter 9 which pulls the transporter 8 and travels on the main transporter rail 3 passes through the branch corresponding to the rail 5 in the roving machine which requires the transporter 8 to be loaded. Then, as shown in FIG. 6 (b), after the rearmost part of the transport body 8 has passed through the travel path switching device 22, a stop position display member (shown in FIG. Z)
After detecting and stopping, it moves backward. Since the lever 24 has returned to the position allowing the transport body 8 to enter the roving in-roof rail 5 at the time when the rearmost portion of the transport body 8 has passed the travel path switching device 22, the transport machine 9 is moved backward. As shown in FIG. 6 (c), the transport body 8 enters the rail 5 in the roving machine from the rear. Then, as shown in FIG.
When the vehicle 20 has entered the branch rail, the transporter 9 stops, and in this state, the uncoupling disconnection device (not shown) is operated to connect the uncoupling unit.
Connection between 20 and carrier 8, namely hook 15 and hook pin 20b
Is disengaged. Thereafter, the transporter 9 moves forward, and the connecting body 20 escapes from the branch rail as shown in FIG. 6 (e), and the transporter 9 moves to a position where the transporter 8 needs to be unloaded.

On the other hand, when unloading the transporting body 8 from the inside of the roving machine inner rail 5, as shown in FIG. 7 (a), an empty transporter 9 running on the main transporting rail 3 needs to be unloaded. 5 is a traveling path switching device that passes through the branch portion 5
At the position passing through 22, the stop position display member is detected by the sensor of the transporter 9 and stopped. Next, the transporter 9 moves backward and stops at a position where the rear end of the connecting body 20 contacts the front end of the transport body 8 as shown in FIG. 7B. Thereby, the hook of the carrier 8
15 automatically engages with the retaining pin 20b of the connecting body 20, and the transporting body 8 and the connecting body 20 are connected. Next, as the transport machine 9 moves forward, the transport body 8 is unloaded from the rail 5 in the roving machine as shown in FIGS. 7 (c) and 7 (d), and the spinning process requires the transport body 8 to be loaded. Transported to

As described above, in the apparatus of this embodiment, the traveling path switching device 22 provided at each branch of the main transport rail 3 and the branch rail is an entry blocking position for blocking the transport body 8 from entering the branch rail. And a lever 24 which is reciprocally rotatable to and from an entry permitting position allowing entry and is always biased and held toward the entry allowing position by a tension spring 29.
A positive driving device for switching the traveling path of the transport body 8 is not necessary, and the transport body 8 is automatically loaded into or out of the branch rail only by moving the transporter 9 forward or backward. It can be performed. In addition, at the time of carrying-in work of the transport body 8, the transport body 8 and the transporter 9 move backward at the arrangement position of the traveling path switching device 22 corresponding to the branch rail other than the branch rail requiring the transport body 8 to be loaded. Since two levers 24 are simultaneously engaged with the engaging rollers 11, 17 and the like, and once placed in the open position, the lever 24 is held at the same position until the rearmost transport body 8 passes, so it is necessary to carry in the lever 24. The traveling path switching device 22 provided at the branch between the main rail 3 and the branch rail other than the branch rail does not hinder the backward movement of the transporter 9 and the transport body 8. Further, the transporter 9 is provided with a connecting body 20 that can travel along the branch rail at a rear portion thereof, and is configured to be connected to the transport body 8 through the connecting body 20. 8 of the carrier from the branch rail
Since the transport machine 9 itself does not enter the branch rail during the unloading work, the branch rail does not need to be provided with a power supply duct necessary for traveling of the transport machine. Become.

Note that the present invention is not limited to the above-described embodiment. For example, the lever 24 of the traveling path switching device 22 is pivotally disposed by the positive drive device between the position where the transport body can enter the branch rail and the position where the transport member is prevented from entering. You may make it. In such a configuration, the transporter 9 can move on the main transport rail by pushing the transporter 8 instead of the configuration in which the transporter 9 pulls and moves the transporter 8.

Effects of the Invention As described in detail above, according to the present invention, the work of carrying in the branch rail or carrying out the work from within the branch rail is performed by retreating and moving forward on the main transfer rail of the transporter. As a result, the structure of the transporter is simpler and smaller and lighter than those of conventional transporters with a built-in bridge rail and transporter. The transport rail becomes strong, and the transporter can travel on the same rail as the rail on which the transporter travels, eliminating the need to provide a dedicated rail for the transporter. Also,
Since the transport machine does not enter the branch rail, there is no need to provide a feed duct required for traveling of the transport machine on the branch rail, and the strength of the branch rail is not required so much, and the equipment cost is reduced. In addition, since the branch rail is formed continuously with the main transfer rail, unlike the conventional device, there is no need to connect the branch rail and the main transfer rail with a bridge rail, and the transport machine stops when loading or unloading the transfer body. There is an excellent effect that it is not necessary to increase the positioning accuracy of the position.
