Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a can conveying system when a can for storing sliver is used to supply sliver produced by a filament machine to a roving frame. , in particular relates to a can conveying system suitable for roving machines.

[Conventional technology]

The process of producing cotton yarn includes a process of passing through a filament machine and a roving machine, with the filament machine producing sliver and the roving machine producing roving yarn. A plurality of these filament machines and roving frames are arranged to form a group, and the filament frame group and the roving frame group are usually installed on different floors or in different areas.

Therefore, the sliver produced by the filament machine is once placed in a drum-shaped container called a can and transported to the roving frame. For example, this can is 635mφ×1524m
It is large in size and is usually transported by carrying several cans on a transport cart. In addition, if the roving frame was installed on a different floor, it was carried to the elevator using a transport cart, then taken to another floor by the elevator, and then transported to the roving frame using a transport cart on another floor. Furthermore, after the actual cans (referring to the cans containing sliver from the filament machine) are transported, empty cans (referring to the empty cans in which the sliver has been consumed by the roving machine) are brought back, and the cans themselves are recycled.

[Problem to be solved by the invention]

The can conveying system using the conveying cart described in the related art requires human labor. Therefore, a transportation system using a self-propelled vehicle that runs on the floor could be considered, but it requires a lot of space to run and requires a large-scale auxiliary device for loading and unloading large cans onto the self-propelled vehicle, making it impractical. It has points. Additionally, if an elevator is used to transport the items to another floor, it takes time to load and unload the items, resulting in an increase in building construction costs.

The present invention has been made in view of such rjia points of the conventional technology, and its purpose is to:
The purpose of the present invention is to provide a can conveying system that can be efficiently conveyed with a simple equipment configuration in a roving frame.

[Means for Solving the Problems] In order to achieve the above object, the can conveying system of the present invention includes a storage conveyor for real cans and/or empty cans for a roving machine, which is arranged on a separate floor, and A ceiling self-propelled vehicle equipped with a can storage cage that can be raised and lowered and suspended from the unloading and unloading areas of Even the station run for empty cans can be hung freely.

[Effect]

A cage on a separate floor that can be raised and lowered by a self-propelled vehicle acts as an elevator, and transports the actual cans and/or empty cans from the replacement station run on the stripping machine to the storage conveyor on the roving machine.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

First, a system for supplying empty cans and discharging actual cans to a group of roving frames arranged on the second floor will be explained with reference to FIGS. 1 to 3.

FIG. 1 is a layout diagram of the second floor where the roving machines are arranged. Two rows of real storage conveyors 13 and two rows of empty storage conveyors 14, which are common to a large number of rover frames 12, are arranged alternately. The second floor reciprocates on the second floor ceiling rail 9 directly above the unloading section 13A of the actual storage conveyor 13 and the unloading section 14A of the empty storage conveyor 14.
A self-propelled vehicle 10 is installed in the ceiling, and an atrium 8 in the floor of the second floor is provided.
Through this, the cage of the second self-propelled vehicle 10 can be suspended up to the exchange stage 5n S4.

Next, the structure of the cage and exchange station of the second ceiling self-propelled vehicle will be explained with reference to FIG. The cage 15 has a rectangular parallelepiped framework, and a comb-shaped floor plate 15A is provided on the bottom surface of the cage 15.
The can C is placed on this floorboard 15A. The exchange station S4 is composed of parallel conveyors 16, and the cans C are transferred onto the parallel conveyors 16 by sinking the floor plate 15A into the gaps 16A between the parallel conveyors 16. Conversely, the cans C on the parallel conveyor 16 are transferred to the cage 15 by lifting the floor plate 15A.

This parallel conveyor 16 is connected to a switching device 17 for the real storage conveyor 5 and the empty storage conveyor 6.7. The switching device 17 reads the identification symbol of the empty can VC and transfers the empty can vC to either of the empty storage conveyors 6.7.
to be carried out. Next, the operation of the cage 15 and the parallel conveyor 16 will be explained with reference to FIG. In FIG. 3(a), the cage 15 carrying the empty cans VC passes through the blowhole 8 and descends directly above the parallel conveyor 16 of the exchange station S4. Then, as shown in FIG. 3(b), the empty can C is carried out to the switching device 17. At the same time, Figure 3 (C)
One actual can FC is carried into the cage 15 from the conveyor 5 as shown in FIG. Next, as shown in Figure 3(d),
The cage 15 carrying the actual Kens FC is lifted to the second floor through the atrium 8.

Then, returning to FIG. 1, the identification symbol of the actual can FC is read, the type is determined, and the actual can is transferred to one of the unloading sections 13A of the actual storage container 13. Also, by receiving and taking empty cans VC from the adjacent loading section 14A and repeating 0 or more operations to return to the state shown in FIG. 3(a), actual cans FC by type are supplied to the conveyor 13.14. And empty Kensuji C is collected. Then, predetermined cans are conveyed from these conveyors 13 and 14 to each roving frame via a transport truck.

FIG. 4 is a layout diagram showing another example of the arrangement of roving frames. Instead of a common conveyor for each rover frame as shown in Figure 1,
A real empty storage conveyor 18 with l-pitch feeding is provided along the roving frame 12, and both ends of the conveyor 18 serve as an unloading section 18A and a loading section 18B. A circular ceiling rail 29 is installed above the unloading section 18A and the loading section 18B, and two ceiling self-propelled vehicles 20.30
is free to run. The actual cans brought in from the exchange station S4 through the open hole 8 are transferred to the unloading section 18A, and the empty cans are picked up at the unloading section 18B of the container and transported through the open hole 8 to the exchange station. This is to be carried to S4.

The ceiling rail 29 is a circle, and two ceiling self-propelled vehicles 2
Since 0.30 is running, efficient conveyance is possible.

Next, the structure and operation of an example of a ceiling self-propelled vehicle in which the above-described cage is suspended and can be raised and lowered will be explained with reference to FIGS. 10 and 11. In FIGS. 10 and 11, the ceiling self-propelled vehicle 1 is
A drive wheel 35 that runs on the roof 2 on a hanger 33 attached to a ceiling beam 31 etc. via a U bolt 32;
It has a driven wheel 36 and a travel motor 37 that drives the drive wheel 35. Moreover, a plurality of guide rollers 38 are provided at the upper part of the ceiling self-propelled vehicle 1 to engage with appropriate positions on the rail 2 in order to prevent the vehicle from rolling on the rail 2. Furthermore, the ceiling self-propelled vehicle 1 is provided with a stop/stop at a suitable place.
A desired number of sensors 39 for detecting passage etc. are provided. Next, a mechanism by which the ceiling self-propelled vehicle 1 suspends the cage so as to be able to rise and fall will be explained. The ceiling self-propelled vehicle 1 has a pair of horizontal shafts 41 for winding and unwinding a plurality of belts 40 for suspending the cage. This horizontal shaft 41 has drums 42 attached to both ends thereof, on which the belt 40 can be directly wound. Further, the horizontal shafts 41 are connected via a timing belt 43 so that they rotate in synchronization with each other. and,
One horizontal shaft 41 is rotated by a lifting motor 45 via a belt 44, thereby winding up and letting out the heald 40. An encoder 46 is provided at the end of the other horizontal shaft 41 to measure the amount of winding or unwinding of the belt 40. Note that a limit switch 47 for detecting the top end position of the cage is also provided at a suitable location.

The above explanation was about the conveyance system for the group of roving machines on the second floor. This is explained by:

FIG. 5 is a diagram showing the travel route of the ceiling self-propelled vehicle and the arrangement of its stations on the first floor. In FIG. 5, a first ceiling self-propelled vehicle 1 travels back and forth on an L-shaped ceiling rail 2,
Four first stage thins 5l-1, 5L- on the straight path 2a
2,5l-3,51-4 are arranged, and the second
Station S2 and two third stations 53-1
, 53-2 and a home position HP are arranged. And the first station S11.5l-2,51
-3 and 51-4 are connected to the plant forms 4 of each of the wire machines 3-1 to 3-4. The second stage tunnel S2 is connected to the platform 5A of the real storage conveyor 5. The third station 53-1, 53-2 is connected to the platforms 6A, 7A of the empty storage container 6.7. In addition, a switching station S4 is located between the actual storage conveyor 5 and the switching device 17, and a second ceiling self-propelled vehicle 1O runs back and forth on the ceiling rail 9 on the second floor through the atrium 8 on the second floor floor. It is connected.

Next, the structure and operation of the platform 4 of the wire forming machines 3-1 to 3-4 will be explained with reference to FIG. The platform 4 consists of a can container hair 4A and an actual can discharge platform 4B. The can conveyor 4A has the function of sequentially conveying the two empty cans VC picked up from the ■ direction on both sides to the ■ direction, and always carries four empty cans vC on both sides of the empty can vC at the 02 position. I'm saving up. Empty can vC in position 02
takes the sliver from the filament machine and makes it into a real Kens FC.
When this happens, the sliver is pushed out in the direction ■ by the butcher plate 4E, and an empty can vC is attached therefrom from the direction ■, and the receiving of the sliver is resumed. The two actual cans FC transferred to the discharge stand 4B are discharged into a cage (not shown) in the manner described below. The discharge table 4B is separately provided with a bushing angle 4D that reciprocates by a rotationally driven screw shaft 4C. This pu.

As the rear angle 4D moves forward in the {circle around (2)} direction, the actual can PC is ejected, and the bushing angle 4D changes from a horizontal state to an upright state, retreats, and returns to its original position.

Further, the cage that moves to each of the stations mentioned above and discharges and receives cans will be explained with reference to FIGS. 7 and 8. A cage 11 having a double rectangular parallelepiped frame structure is attached to four belts 40 unwound from a ceiling self-propelled vehicle to be described later. As shown in Figure 8, there are two
It has a structure in which cans C can be placed thereon, and the cans C pushed out in the direction {circle around (2)} are received at the position indicated by the two-dot chain line by the free roller row 11A and the side guide IIB.

Further, the can C is pushed out in the {circle around (2)} direction and discharged by the bushing plate IIC which reciprocates by a screw shaft (not shown). Returning to Figure 5, the center position of this cage is 0.
With reference to, the first stations 5l-1, 5L-2,
When suspended up to 51-3 and 5L-4, the cage has three stopping positions: 1fP1 (marked with O), P2 (marked with *),
It has P3 (◎ mark). Further, the second station S2 has one stop position P4 (in the mouth), and the third stations 53-1 and 53-2 each have one stop position P5 (◇ mark) and P6 (◆ mark). There is.

Further, the operation of the cage 11 at the stop positions PI and P2P3 of the first station will be explained with reference to FIG. Figure 9 (a
), the cage 11 is lowered to the same height as the platform 4. Then, as shown in FIG. 9(b), as the bushing plate 11C moves forward, the empty can vC is pushed out to one of the can conveyors 4A and discharged. Next, as shown in FIG. 9(c), the cage 11 is moved to the stop position P2 by the traveling of the ceiling self-propelled vehicle. And Figure 9 (
As in d), by the advancement of the bushing plate IIC,
The empty can vC is pushed out to the other can conveyor 4A and discharged. Next, as shown in FIG. 9(e), the cage 11 is moved to the stop position P3 by the traveling of the ceiling self-propelled vehicle. At this time, the button plate llc has returned to its original position.

Then, as shown in FIG. 9(f), the cage 11 receives the two actual cans FC at the same time by advancing the bushing angle 4D on the discharge table 4B side. Also, according to FIG. 5, the stop position P4 of the second and third stations. P5. The cage operation at P6 will be explained. The cage which received the two actual cans at the first station moves after rising to the upper limit position, and descends to the same height as the plant form 5A at the stop position P4. And the Butsusha plate 1 in Figure 8
By advancing 1C, two real cans FC are transferred to conveyor 5.
Extrude and discharge. In this way, a large number of actual cans FC are stored in the container 5. Next, the empty cage rises to the upper limit position at the stop position P4, moves, and waits at the home position HP. And, the line machine 3-1
- 4, the empty cage is moved to the stop position P5 or P6 and lowered to the same height as the platform 6A or 7A. Then, two empty cans vC on the conveyor 6 or 7 are taken into the cage at the same time. The reason for providing two rows of conhairs 6.7 is as follows. Not all of the striping machines 3-1 to 3-4 process different types of wire, for example, there are two types.

This type identification is performed by reading an identification symbol such as a bar code or colored tape pasted on the can, or a colored rubber band wrapped around the can. Therefore, the can exchange signals of the wire stripping machines 31 to 4 determine which type is to be processed, and in order to send empty cans corresponding to the type, there are two rows of conhairs 6.7 for each type. In subsequent processing of actual cans, by reading the identification symbol of the actual can, it is possible to determine automatically or manually which storage conveyor or roving machine the actual can should be transported to.

In addition, although the above description is based on the case where the cage 11 in FIG. 7 is provided with the pusher plate IC, each station may be provided with a pusher for pushing out the cans in the cage II. Moreover, the ceiling rail 2 in FIG. 5 can also be made into a circle shape as in FIG. 4 to form two ceiling self-propelled vehicles.

Next, a series of conveyance systems between the wire frame and the roving frame will be explained with reference to FIGS. 5 and 1.

In FIG. 5, after the receiver determines the type of empty can VC to be taken by the can exchange signal of the wire machine, the ceiling self-propelled vehicle at the home position HP moves to the third station 53-
1 or 53-2, and after stopping at the stop position P5 or P6, the cage is hung. After picking up the two empty cans vC, the car moves to the plant form 4 of the wire machine, which raises the cage and issues a can exchange signal. Then, after stopping at the stop position P1 of the first station,
Hang the cage and eject one empty can. Next, after lifting the cage a little and moving it to the stop position P2,
The cage is raised to a predetermined height and the remaining empty can VC is discharged. Next, after lifting the cage a little and moving it to the stop position P3, the cage is set to a predetermined height, the FCs of the two actual cans are taken off, the cage is raised, and the cage is moved to the second station S2. Suspend the cage at stop position P4,
Two actual cans FC are discharged onto the platform 5A, and a large number of actual cans FC are stored on the conveyor 5.

Then, the cage of the self-propelled vehicle 10 on the second floor carries the empty can and is suspended from the exchange station S4.

One empty can VC is transferred to the switching device 17, and one actual can is also transferred. The type of empty can vC in the switching device 17 is determined and stored on either the conveyor 6 or 7. In FIG. 1, the type of actual cans is determined, and the cans are transferred to one of the unloading sections 13A of the conveyor 13. The empty can is transferred to the adjacent loading section 14A, and suspended from the open hole 8 to the exchange station S4. As described above, the conveyance of cans between the filament machine and the roving frame is automated without using a transport truck or an elevator.

〔Effect of the invention〕

The can conveying system of the present invention has storage conhairs for real cans and/or empty cans for a roving machine arranged on separate floors, and is suspended up and down to the unloading section and the loading section of the storage conhairs. A self-propelled ceiling vehicle equipped with a can storage cage is installed on a ceiling rail on another floor so that it can run freely, and the cage can be freely suspended from an atrium on another floor to an exchange station for actual cans and empty cans, A cage on a separate floor that can be raised and lowered by a self-propelled car on the ceiling acts as an elevator, and transports the actual cans and/or empty cans from the exchange station on the stripping machine side to the storage container for actual cans and/or empty cans on the roving machine side. Loading and unloading time can be saved, and the need for a large-scale elevator for transporting cans can also be eliminated.
