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 drawing machine to a roving frame. In particular, the present invention relates to a can conveying system suitable for a drawing machine.

[Conventional technology]

The process of making cotton yarn involves passing through a drawing machine and a roving machine.
It is made into roving yarn using a roving frame. A plurality of these drawing machines and roving frames are arranged to form a group, and the drawing machine group and the roving frame group are usually installed on different floors or in different areas. Therefore,
The sliver produced by the drawing machine is placed in a drum-shaped container called a can and transported to the roving frame. For example, this can is 635mmφ×1524mm
It is large in size and is usually transported with several cans placed on a transport trolley. 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 drawing 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 is impractical because it requires a lot of space and requires a large-scale auxiliary device to load and unload large cans onto the self-propelled vehicle. It has points.

The present invention has been made in view of the problems of the conventional technology, and its purpose is to provide a can conveying system that can be efficiently conveyed with a simple equipment configuration in a group of drawing machines. This is what I am trying to do.

[Means to solve the problem]

In order to achieve the above object, the can conveying system of the present invention includes a first station for discharging empty cans and receiving a full can at the end of each drawing machine, a second station for discharging full cans, and a second station for receiving empty cans. 3 stations, and a ceiling self-propelled vehicle equipped with a can storage cage that can be raised and lowered and suspended from each station is movably mounted on a ceiling rail.

[Effect]

At a predetermined station, a ceiling self-propelled vehicle lowers the cage to store the cans, raises the cage and transports the cans to the designated station, lowers the cage and pushes out the cans, so that the cans are automatically transported. Ru.

〔Example〕

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

First, we installed a system for supplying empty cans and discharging actual cans to the group of drawing machines arranged on the first floor.
This will be explained with reference to FIGS. 5 to 5.

FIG. 1 is a diagram showing the travel route of a ceiling self-propelled vehicle and the arrangement of its stations on the first floor. 1st
In the figure, a first ceiling self-propelled vehicle 1 reciprocates on an L-shaped ceiling rail 2, and passes four first stations S1-1, S1-2, S1-3, and S1 on a straight path 2a.
-4 is arranged, and a second station S2 and two third stations S3-1 and S3 are arranged on the straight path 2b.
-2 and home position HP are arranged. And the first station S1-1, S1-
2, S1-3, and S1-4 are connected to the platforms 4 of each of the drawing machines 3-1 to 3-4. Second
Station S2 is connected to platform 5A of real storage conveyor 5. The third station S3-1, S3-2 is connected to the platforms 6A, 7A of the empty storage conveyors 6,7. In addition, a switching station S4 is provided between the actual storage conveyor 5 and the switching device 17, and a second ceiling self-propelled vehicle 10 that travels back and forth on the ceiling rail 9 on the second floor passes through the atrium 8 on the second floor floor surface.
is connected to.

Next, the structure and operation of the platform 4 of the drawing machines 3-1 to 3-4 will be explained with reference to FIG. The platform 4 consists of a can conveyor 4A and an actual can discharge table 4B. Can conveyor 4A
is two empty cans received from both sides.
It has the function of transporting VC in sequential directions, and always stores four empty cans VC on both sides of the empty can VC at position 02. The empty cans VC at position 02 is

is attached and sliver reception resumes. Two real cans FC transferred to discharge platform 4B
is discharged into a cage, not shown, in the manner described below. A pusher angle 4D that reciprocates on a rotationally driven screw shaft 4C is separately provided on the discharge table 4B. As the pusher angle 4D advances in the direction, the actual can FC is ejected, and the pusher angle 4D changes from a horizontal state to an upright state and retreats to return to its original position.

In addition, the cages that move to each of the stations mentioned above and discharge and receive cans are shown in Figures 3 and 4.
This will be explained using figures. 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 4, there are two cans C on the left and right of the center O.
It has a structure in which cans C can be placed thereon, and cans C pushed out in the direction are received by the free roller row 11A and the side guide 11B at the position indicated by the two-dot chain line.
Further, the can C is pushed out in a direction by a pusher plate 11C that reciprocates by a screw shaft (not shown) and is discharged. Returning to FIG. 1, when the cage is suspended from the center position O of the cage to the first stations S1-1, S1-2, S1-3, and S1-4, the cage has three stop positions P1. (○ mark), P2 (● mark), and P3 (◎ mark). Furthermore, the second station S2 has one stop position P4 (□ mark), and the third stations S3-1 and S3-2 each have one stop position P5 (◇ mark) and P6 (◆ mark). ing.

In addition, the stop positions P1 and P of the first station are
2. The operation of the cage 11 at P3 will be explained with reference to FIG. In FIG. 5a, the cage 11 is lowered to the same level as the platform 4. In FIG. and,
As shown in FIG. 5b, as the pusher plate 11C moves forward, the empty cans VC are pushed out to one of the can conveyors 4A and discharged. Next, Figure 5c
As shown, the cage 11 moves to the stop position P2 as the ceiling self-propelled vehicle moves. Then, as shown in FIG. 5d, as the pusher plate 11C moves forward,
The empty can VC is pushed out to the other can conveyor 4A. Next, as shown in FIG.

Explain the operation of the cage. The cage which has received two actual cans at the first station moves up to the upper limit position and then moves down to the same height as the platform 5A at the stop position P4. and,
By advancing the pusher plate 11C shown in FIG. 4, two actual cans FC are pushed onto the conveyor 5 and discharged. In this way, a large number of actual cans FC are stored on the conveyor 5. Next, the empty cage rises to the upper limit position at the stop position P4, moves, and waits at the home position HP. Then, the empty can is moved to the stop position P5 or P6 by the can exchange signal from any of the ridge machines 3-1 to 3-4, and then transferred to the platform 6A or 7A.
descend to the same height. Two empty cans VC from conveyor 6 or 7 are received by the cage at the same time. The reason why two rows of conveyors 6 and 7 are provided in this way is as follows. Draw machine 3-1~4
do not all process the same variety; for example, there are two varieties. 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 drawing machine 3-
The can exchange signals 1 to 4 determine which type is to be processed, and two rows of conveyors 6 and 7 are provided for each type to feed empty cans corresponding to the type. In the 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 can should be transported to.

In addition, although the above description is based on the case where the pusher plate 11C is provided in the cage 11 shown in FIG. 3, it is also possible to provide a pusher for pushing out the can inside the cage 11 at each station.

Next, the structure and operation of an example of a ceiling self-propelled vehicle in which the above-mentioned cage is suspended and can be raised and lowered are shown in Figures 10 and 1.
This will be explained using Figure 1. 10 and 11, the ceiling self-propelled vehicle 1 has a driving wheel 35 running on a rail 2 on a hanger 33 attached to a ceiling beam 31 etc. via a U bolt 32, and a driven wheel 36.
It also has a travel motor 37 that drives the drive wheels 35. Furthermore, 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 rolling on the rail 2. In addition, ceiling self-propelled car 1
A desired number of sensors 39 for detecting stopping, passing, etc. are provided at appropriate locations. 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 shaft 41 is connected to a timing belt 43 so as to be rotated in synchronization with each other.
connected via. One of the horizontal shafts 41 is rotated by a lifting motor 45 via a belt 44, thereby winding up and letting out the belt 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 uppermost position of the cage is provided at a suitable location.

The above explanation has been about the conveyance system for the group of drawing machines on the first floor, but the conveyance of cans to the group of roving frames arranged on the second floor will be explained below. FIG. 6 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. A second ceiling self-propelled vehicle 10 is provided which reciprocates on the second floor ceiling rail 9 directly above the unloading section 13A of the actual storage conveyor 13 and the loading section 14A of the empty storage conveyor 14. The cage of the second overhead self-propelled vehicle 10 can be suspended through the atrium 8 to the exchange station 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 is a rectangular parallelepiped framework, and a comb-shaped floor plate 15A is provided on the bottom surface of the cage 15, and the can C is placed on this floor plate 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 gap 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 conveyors 6, 7. The switching device 17 reads the identification symbol of the empty can VC and carries out the empty can VC to either the empty storage conveyor 6 or 7. Next, the operation of the cage 15 and the parallel conveyor 16 will be explained with reference to FIG. In FIG. 8a, the cage 15 carrying the empty cans VC passes through the blow-through hole 8 and descends directly above the parallel conveyor 16 of the exchange station S4. Then, as shown in FIG. 8b, the empty can VC is carried out to the switching device 17. At the same time, one actual can FC is carried into the cage 15 from the conveyor 5, as shown in FIG. 8c. Next, as shown in FIG. 8d, the cage 15 carrying the actual can FC is lifted to the second floor through the atrium 8. Then, returning to FIG. 6, the identification symbol of the actual can FC is read, the type is determined, and the actual can FC is transferred to one of the unloading sections 13A of the actual storage conveyor 13. Also, I received an empty can VC from the loading section 14A next door,
Return to the state shown in FIG. 8a. By repeating the above operations, actual cans FC by type are supplied to the conveyors 13 and 14 and empty cans VC are collected. Then, predetermined cans are transported from these conveyors 13 and 14 to each roving frame via a transport truck.

FIG. 9 is a layout diagram showing an example of arrangement of other roving frames. Instead of a common conveyor for each rover frame as shown in FIG. 6, a real empty storage conveyor 18 for one-pitch feeding is provided along the rover frame 12, and both ends of the conveyor 18 are connected to an unloading section 18A and a loading section 1.
It is marked 8B. A circular ceiling rail 29 is provided on the unloading section 18A and the loading section 18B.
has been erected, and two overhead self-propelled vehicles 20 and 30
is now free to run. The actual cans carried from the exchange station S4 through the open hole 8 are transferred to the unloading section 18A, and the empty cans are received at the unloading section 18B of the same conveyor and transported through the open hole 8 to the exchange station S4. It is something. Since the ceiling rail 29 is in the form of a circle and the two ceiling self-propelled vehicles 20 and 30 are running, efficient transportation is possible. Similarly, the ceiling rail 2 shown in FIG. 1 can also be shaped into a circle to form two ceiling self-propelled vehicles.

Next, a series of conveyance systems between the drawing machine and the roving frame will be explained with reference to FIGS. 1 and 6.

In Figure 1, after determining the type of empty can VC to be received by the can exchange signal of the drawing machine,
The ceiling self-propelled car on the home position HP is the third one.
Travel to station S3-1 or S3-2,
After stopping at the stop position P5 or P6, the cage is suspended. After receiving the two empty cans VC, the cage is raised and the cage is moved to platform 4 of the drawing machine, where a can exchange signal is issued. After stopping at the stop position P1 of the first station, the cage is suspended and one empty can is discharged. Next, lift the cage slightly to stop position P2.
After moving the cage to the specified height, the remaining 1
Empty empty cans VC. Next, after lifting the cage a little and moving it to the stop position P3, the cage is set to a predetermined height, the two real cans are received from the FC, the cage is raised, and the cage is moved to the second station S2.
Run until. Suspend the cage at stop position P4 and attach two real cans FC to platform 5A.
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 cans VC in the switching device 17 is determined and stored on either the conveyor 6 or 7. In FIG. 6, 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 transportation of cans between the drawing machine and the roving frame is automated without using a transport cart or an elevator.

〔Effect of the invention〕

The can conveying system of the present invention includes a first station for discharging empty cans and receiving a full can at the end of each drawing machine, a second station for discharging full cans, and a third station for receiving empty cans. A ceiling self-propelled vehicle equipped with a can storage cage that can be raised and lowered and suspended from each station is installed on a ceiling rail so that it can freely travel.At a designated station, the ceiling self-propelled vehicle lowers the cage and stores the cans. , the cage is raised and transported to a designated station by an overhead self-propelled vehicle, the cage is lowered and the can is pushed out.
Large cans can be easily loaded and unloaded in a designated position without requiring any space on the floor for running.
