DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for a processing apparatus used in a package transfer apparatus for transferring a package formed by a yarn processing apparatus such as a draw false twisting machine by a ceiling transfer vehicle.

[0002]

2. Description of the Related Art For example, in a draw false twisting machine, a preheater is preheated by a primary heater while applying stretching between feed rollers, and then preheated by a nip twister, followed by heat treatment by a secondary heater while stretching between feed rollers. After that, an oiling process or the like is performed, and the film is wound into a package. A number of such draw false twisters are provided adjacent to each other to form a draw false twist line, and a number of these draw false twist lines are provided to form a draw false twist line. A number of machine lines are juxtaposed to form a draw false twisting factory.

In such a draw false twisting factory, when doffing and conveying a package formed by each draw false twisting machine, an automatic doffing machine common to adjacent draw false twisting machines, that is, a traveling line of an autodoffer is used. And a package transport conveyor line with pegs to insert the package doffed by the autodoffer in a horizontal direction is arranged in parallel with the traveling line of the autodoffer, and each stretch false twist that supports and transports the doffed package. A conveyor line for each machine row is provided at a side end of each machine row to be a transfer station. The packages transported to the transfer station by the package transport conveyors of each line are transferred to the overhead transfer vehicles that circulate through the transfer stations of each line, and the overhead transfer vehicles unload these packages at the station. Unload and circulate again to the transfer station. The packages unloaded at the unloading stations on the ceiling transport lines provided for each of the draw false twisting machine lines are carried out for the next process such as the next weaving factory.

On the other hand, an overhead traveling vehicle traveling on each overhead transportation line needs to have a capability of transferring and transporting a package produced by a draw false twister from a conveyor without delay,
Therefore, among the various types of yarns processed by the draw false twisting machine, the ceiling transport vehicle capable of coping with the production amount of the type with the highest processing speed, that is, the type with the largest amount of doffing in a certain time Is always running on the ceiling transport line.

[0005]

In the above-described package transfer device, the ceiling transfer vehicle corresponds to the yarn having the fastest processing speed and the fastest doffing speed among the yarns of various types processed by the draw false twisting machine. Since all the packages can be smoothly transported, the number of overhead transport vehicles is that an extra number of overhead transport vehicles are traveling when normal packages are transported.

In particular, in the case of a yarn having a slow processing speed, it is necessary to circulate a larger amount of unnecessary overhead transport vehicles, and this occurs in each overhead transport line. In addition to the need for overhead transport vehicles, it requires unnecessary traveling energy to constantly send empty overhead transport vehicles, and also requires periodic inspections for every fixed travel, which is an uneconomic transport device. Had become.

Accordingly, the present invention provides a control system for a processing apparatus used in a package transfer apparatus or the like capable of transferring a package by running a minimum necessary number of overhead transfer vehicles without constantly circulating unnecessary overhead transfer vehicles. The purpose is to provide.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to connect a ceiling transport vehicle storage line for supplying or taking in an overhead transport vehicle to a package transport line of the overhead transport vehicle and to process each yarn. A control system for a processing apparatus is provided by providing a ceiling transport vehicle traveling number control device that supplies or takes in the overhead transport vehicles of the package transport line from the overhead transport vehicle storage line according to the package forming speed in the apparatus. Thus, only the minimum required overhead transport vehicle can be run on the package transport line.

[0009]

Since the present invention is constructed as described above, the overhead transport vehicle traveling on the package transport line transports the doffed packages formed after being processed by the respective yarn processing devices. The processing speed of the overhead transport vehicle differs depending on the situation in which the yarn is processed by the yarn processing apparatus, and accordingly, the number of ceiling transport vehicles that transport the formed package is increased in response to the different package forming speeds. When a large number is required, the required number of vehicles are supplied from the overhead carrier storage line via the traverser in response to a signal from the overhead carrier vehicle traveling number control device. Also, the package formation speed is slow,
When the number of overhead transport vehicles is too large, the overhead transport vehicles are taken into the overhead transport vehicle storage line via a traverser from the package transport line in response to a signal from the overhead transport vehicle traveling number control device, and on the package transport line, At all times, only the required minimum overhead transport vehicle corresponding to the package forming speed is run.

The package transport conveyor 14-1 arranged to circulate around the outer periphery of the first heater 4 has a transfer station 1 at a turn portion at the end of the creel row.
8-1 and a ceiling conveyor line 20 for unloading the conveyed packages at the transfer stations 18-1,..., 18-n of each of the similarly configured package conveyors.

The ceiling conveyor line 20 is formed so as to be able to run by circulating through an overhead conveyor 21 traveling on the line.
Transfer station 1 shared with transfer station 18 of No. 4
The ceiling transport vehicle 21 stops at this position, and lowers the elevating support 23 supported at the lower part of the transport vehicle body 22, as shown in FIG.

The elevating support 23 is provided with three pegs 24 as shown in FIG.
It has. Therefore, when the overhead carrier stops at the transfer station 18 and lowers the elevating support 23, the guide ring 25 is fitted to the guide rod 26 erected immediately below the elevating support 23, thereby lowering the elevating support 23. Is accurately lowered to a predetermined position of the transfer station 18.

A 0 moves from peg 28 to opposing peg 24.

When the package P is transferred to the elevating support 23, the elevating support 23 is lifted by the carrier body 22, and the overhead traveling vehicle 21 travels on the overhead conveyer line 20, and the unloading station shown in FIG. The package is transported to 31. At the unloading station 31, the elevating support 23 is lowered and unloaded onto the package stocker 32. The empty elevating support 23 is lifted again, travels along the circulation path of the ceiling conveyor line 20, and carries the same package.

Such a package transfer device is similarly provided in each of the draw false twister lines 17-1, 17-2, 17-3, and a plurality of ceiling transfer vehicles run on each ceiling conveyor line 20. doing.

In each of the ceiling conveyor lines 20, a portion disposed beyond the unloading station 31 is provided with a ceiling transport vehicle transfer section 34 which is adjacent to a ceiling transport vehicle storage line 33 to be described later. Traverser 35 provided
Thereby, the transfer of the ceiling transport vehicle between the ceiling conveyor line 20 and the ceiling transport vehicle storage line is enabled.

The overhead transport vehicle storage line 33 is provided with an overhead transport vehicle storage section 36 for storing items other than the overhead transport vehicles currently required in the draw false twisting factory. Therefore, in one drawing false twisting machine line 17-2, when the type of the yarn to be drawn false twisted is changed and the yarn processing speed becomes slow, for example, the yarn is passed through the primary heater over a longer time. Since the number of packages to be formed per unit time is reduced, the number of overhead transport vehicles for transporting the packages can be reduced, and circulating extra overhead transport vehicles causes much waste. At that time, the required number of ceiling transport vehicles corresponding to the type of yarn to be false-twisted is output by a separate control device, and the extra ceiling transport vehicle is transferred to the overhead transport vehicle transfer unit 34 by the traverser 35. It is transferred to the storage line 33.

Further, when the type of the yarn to be subjected to the draw false twist is further changed and the processing speed of the yarn is increased, the number of packages to be formed per unit increases, so that the number of ceiling transport vehicles is insufficient. Therefore, the required number is output by the control device, the overhead transport vehicle stored in the overhead transport vehicle storage section 36 is run, and the traverser 35 in the overhead transport vehicle transfer section 34 supplies the required number to the ceiling conveyor line 20. The number is transferred.

The above control is performed by a control device (not shown) according to the flow shown in FIG. That is, in the control device, the following control flow is performed corresponding to each drawing false twisting machine line 17, and when the type of yarn to be processed changes, the production type information is manually or from another drawing false twist control device. It is input (step 41). From the memory 42 provided initially therein in the controller, already reads the number N ₁ of the ceiling transport vehicle on which the vehicle is currently traveling which is stored (step 43). Then by the previous product type information to calculate the required number N ₂ of the ceiling transport vehicle (step 44). This value N ₂ is input to the memory 42, and stores the N ₂ erases the previously stored value N _1. This value N ₂ is calculated by the difference calculation step 4
In step 5, the calculation of N ₁ −N ₂ = N ₃ is performed, and in the determination step 46, when N ₃ ≧ 0,
When N ₃ <0, the process proceeds to step 48. Step 46
At a, it is determined whether or not N = 0, and when N ≠ 0, the process proceeds to step 47. When N = 0, the process is terminated. Step 47
In, the control unit 49 of the traverser, issues an output for supplying N ₃ units guided vehicles from ceiling transport vehicle reservoir line to the ceiling conveyor line, in step 48, preparative N ₃ units guided vehicles conversely Output

In this control apparatus, not only the supply and the control of the number of the overhead transport vehicles are controlled, but also the individual information of all the overhead transport vehicles used in the factory is taken.
It is also possible to manage the traveling or storage status one by one, and to manage the specific overhead transport vehicle so that it can be used evenly without traveling for a long time.

The type of yarn to be processed by the drawing false twisting machine may be changed not in the entire drawing false twisting machine line but in each drawing false twisting machine row unit. Calculates the required number of overhead transport vehicles in each line based on the information.

In the above embodiment, an example is shown in which the package conveying apparatus of the present invention is applied to a stretching machine.
