Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for collecting and transporting wound yarn in a factory where a large number of textile machines each having a large number of winding units arranged in rows are installed.

More specifically, the present invention relates to a conveying method that includes a step of inspecting the physical properties of the surface layer yarn of the wound yarn and a layer-based sorting step during the conveying route.

The work of collecting and transporting wound yarn in silk mills, texture processing factories, spinning factories, etc. is difficult due to the large number of pieces.
For one thing, it is easy for threads to become stained, packages to be damaged, etc., and handling is cumbersome, which places a heavy burden on workers, so there is a great need for automated equipment that can perform the process efficiently and without errors.

Traditionally, winding thread has been transported by machine unit,
A method has been proposed in which a continuous conveyor is used to transport the threads individually, but there are problems with the correspondence between the position of the thread on the conveyance route and the machine where the thread was produced, and the position of the winding unit where the thread was wound. In many cases, it is more convenient to use a transporter for each machine when it is necessary to deal with this problem and the hoisting time.

However, this transportation method that has already been proposed has the following drawbacks.

First of all, regarding the method of loading yarn onto a conveyor at the same time as doffing, the conveyor must be prepared prior to doffing, and the operation of the conveyor is greatly influenced by the doffing schedule. Since it is tied to the machine base, the number of conveyors increases, making it impossible to operate efficiently o Also, based on the results of winding yarn inspections (representative inspections, sampling inspections, etc.) obtained using the above method, When sorting, the threads must be stored until the results are known, or the threads must be stored in a carrier in a predetermined order so that the test results correspond to each thread.

Furthermore, if there is a mixture of spools that require inspection and spools that do not require inspection in the conveyor, it is possible to sort the spools in other conveyors based on the inspection results. This makes it extremely difficult to deal with it.

The purpose of the present invention is to improve the defects of the prior art as described above, to maintain the doffing order of the yarn produced by each machine, and to clarify the correspondence with each winding unit to supply the yarn to the inspection process. The purpose of this invention is to provide a new method for collecting and transporting wound yarn.

The present invention has the following configuration to achieve the above object.

In other words, in a method in which a plurality of textile machines each having a large number of winding units arranged in rows are installed and the yarn produced from these machines is collected and transported, the yarn doffed from each winding unit is At least one of the doffed pieces is stored in a reserve device provided corresponding to the take-up unit, and then the doffed pieces are stored in a storage device provided corresponding to the take-up unit, and then the doffed pieces are stored in a storage device provided corresponding to the take-up unit. A yarn transport mechanism equipped with a yarn storage device was introduced at a position facing the reserve device, and the yarn located at the outermost side of the reserve device was transferred to the yarn storage device located at a position corresponding to the reserve device. The basic invention is a method for collecting and transporting wound yarn, which is characterized in that the yarn is then transported to an inspection or sorting process in units of transport mechanisms.

The present invention has the following features based on the above-described configuration.

First, the doffed yarn is temporarily stored in the reserve device, so the operation of the doffing machine and the installation of the conveying mechanism can be carried out independently of each other, and there is no interference between the two.

Therefore, the conveyance mechanism can pick up the doffed yarn from any machine at any time, and can transfer the yarn from the reserve device to the conveyance mechanism within a short time.

In addition, the yarn that is waiting for inspection results is placed on the conveyance mechanism and is on standby, and the yarn that is not transferred to the conveyance mechanism is also stored in the reserve device while maintaining the order of doffing. Therefore, the order and arrangement of these items will not be confused during the storage or transportation process.

Furthermore, by determining inspection or non-inspection for each transport mechanism, the correspondence between the inspection results and the order and arrangement of the winding threads is maintained, making the next classification reliable and easy.

The present invention will be explained in more detail below with reference to the drawings.

Fig. 1 shows an example of an apparatus used to carry out the method according to the present invention, and Fig. 2 is a plane showing a moving path of a machine and other attached equipment and a transport mechanism for carrying out the method according to the present invention. It is a diagram.

In FIG. 1, a yarn 2 that has passed through a processing section 1 that performs yarn processing such as drawing, false twisting, and spinning is wound onto a bobbin 10 by a winding unit 3.

The doffing from the winding unit 3 travels on the platform 5 along the front surface of the machine which is equipped with a large number of winding units 3 in a row 1.
The doffed yarn is sequentially doffed by an automatic doffing machine 6, and the doffed yarn is transferred to a reserve device 4 provided opposite to each winding unit 3.

Each reserve device 4 has one or more, and at most three, winding threads (
In FIG. 1, the structure is such that two (2) winding yarns 10a, 10b can be stored while keeping the surfaces of the yarn layers not in contact with each other.

FIG. 3 is a perspective view showing an example of a reserve device, and each reserve device 4 consists of a pair of reserve rails A and A', which are inclined with respect to the horizontal, with the winding unit side being higher and the yarn discharge side being lower. It's meant to be.

In order to lock the winding threads 10a and 10b at predetermined positions of the reserve device, stoppers B and B' are provided to support the paper tube ends of the winding threads 10at10b, and the stoppers B and B' are fixed to the rods c and c', respectively. has been done.

By rotating this rod C or C', the winding thread 1
Qa, 10b can be moved.

For example, when the illustrated rod C is operated to release the lock of the winding thread 10b, the winding thread 10b of the middle reserve device is removed from the reserve device.

The removed thread is stored in a thread storage container 9 of the transport mechanism 8 shown in FIG.
will be automatically transferred to.

Operate rod C to return stock movers B and B/ to their correct positions.

Next, when the rond C' is operated as described above, the winding thread 10a moves to the position of the winding thread 10b, and the position of the winding thread 10a becomes vacant to secure the position of the winding thread to be doffed next.

The reserve device is not limited to the embodiment shown in FIG. 3, but other types besides a conveyor type can also be used.

A single machine has a structure in which all the individual reserve devices are operated at the same time, and each reserve device has a structure in which the winding threads in the same row are doffed at the same time. The winding yarn (hereinafter referred to as the winding yarn number) is stored.

In a winding unit that temporarily stops producing winding yarn, the reserve position of that winding yarn number becomes vacant.

In addition, when thread breakage occurs due to some trouble during the process, and two or more winding threads have the same winding thread number, if two or more winding threads have the same winding thread number, putting the extra winding thread into the reserve device will disrupt the winding order. Any excess of these should be removed each time.

The outermost yarn on the reserve device 4 is introduced along the back side of the machine via the rail 7 into a conveyance mechanism 8, where the yarns having the same winding number on one side of the machine are loaded all at once.

The conveying mechanism 8 includes a winding yarn storage container 9 corresponding to each winding unit, and although it is divided into several blocks, these blocks are interconnected to form a series of trains.

The transport mechanism 8 can be moved along the rails 7 by means of an electric vehicle or other suitable traction device 17 as shown in FIG.

In FIG. 2, the doffing machine 616 is carried to the end of the winding unit row 11.11 of the doffing machine base by the carrier 12 moving on the doffing machine moving rail 13 provided separately from the rail 7. After being discovered, it runs doffing over Plats 5 and 5.

The running rail 7 of the transport mechanism 8 is guided to the back side of each winding unit row 11 from the side opposite to the side where the doffing machine movement rail 13 is provided, and the other end passes through a plurality of pool line rails 7a and is used for inspection and sorting. It is connected to the line rail 7b or the immediate sorting line rail 7C.

A bypass rail 7d can also be provided if necessary.

The conveyor 8 loaded with the winding yarn temporarily pooled on the pool line rail 7a follows a predetermined logical command, that is, (
a) 100% inspection in which all wound yarns are inspected; (b) representative inspection in which only the wound yarns stacked on some conveyor mechanisms 8 are inspected, and the yarns on other conveyor mechanisms 8 are sorted based on the results. , (c) Random sampling inspection in which all yarns on the transport mechanism 8 randomly selected for the purpose of checking the manufacturing process of the yarn are inspected, (d) Contamination of abnormal yarns based on the management information of the manufacturing process. In accordance with a command such as a special inspection such as inspecting all the yarns on the conveying mechanism 8 that may have a possibility of being carried, the yarn is conveyed to the line of the rail 7b or rail 7c.

When inspecting all the produced yarns, the transport mechanism 8 loaded with yarns is all placed on the rail 7b.

FIG. 4 is a perspective view showing an example of the inspection and sorting device.

As shown in FIG. 4, when the conveyor machine 8 arrives at the inspection and sorting line 7b, the yarn loaded on the conveyor mechanism 8 is transferred to the robot by rotating the conveyor 14 intermittently in the direction of the arrow.
8, the pieces are transferred one by one to the loading position K on the conveyor.

At this time, the winding permutation on the transport mechanism 8 and the winding permutation on the conveyor 14 are made to correspond completely, and a vacant seat on the transport mechanism 8 is also treated as a vacant seat on the conveyor 14.

When the thread on the conveyor 14 comes to the exit position L, the thread is automatically taken out.

Further, the conveyor 14 moves and the winding thread 10 moves to the sample collection position M.
reach the position.

At this position, the yarn end of the standard wound yarn 22 used as a comparison standard for testing dyeing properties and the like is connected as a guiding yarn to the inspection device 21 via the switching device 20.

When the winding thread 10 arrives at the position M, the opening thread and the inspection device 2
1 to the end of the standard wound thread 22 is connected by the switching device 20, and the thread on the side of the standard wound thread 22 is cut and transferred to the inspection device 21.
The winding yarns on the conveyor are sequentially supplied with surface layer yarns of a fixed length connected in series as samples.

The inspection results of the sampled surface layer yarn are obtained while the winding yarn 10 is from the position M to the winding yarn stacking and unloading position N from the conveyor, and the results and other qualities obtained from the previous processes are determined. The information is sequentially input to the robot 19, and the winding yarns 10 are automatically unloaded onto the sorting conveyor 15 while being sorted at the N position.

In this way, the yarn is conveyed to the conveyor 14 until the inspection results are obtained.
By storing the yarn on standby, it is easy to correspond to the winding sequence and sorting information during sorting, and there is no need to track the individual winding sequences after unloading from the conveyor 14. Only group management for 8 organizations is possible,
The software for subsequent process automation has been greatly simplified and reliability has been improved.Also, even if the surface layer yarn has been collected, if re-collection is necessary due to trouble with the inspection device 21, etc., the conveyor Since the wound thread remains on the sample 14, it is advantageous to collect the sample again.

The winding yarn on the sorting conveyor 15 is placed in the weighing, packaging, and packing section 16.
It is carried to the next process such as

Inspection results that correspond to the individual winding units of the machine are also useful for process control.

The empty transport mechanism 8 is introduced into the next loading machine 11 through the empty rail 7a or the bypass line 7d.

In the above explanation of Fig. 4, we have described the case where the operations of loading thread onto the conveyor 14, taking samples from the surface of the winding yarn and inspecting it, and sorting and loading and unloading are performed in parallel. The method of operation is to take out the threads and collect the surface layer threads, inspect the collected sample threads for each unit loft, and once the results are available, sorting, loading and unloading will be carried out for each unit loft. But it's okay.

This method is applied to a tube knitting dyeing test using the inspection device 21 as a tube knitting machine.

Next, an example in the case of a representative test will be described.

FIGS. 5, 6, and 7 illustrate three different methods for selecting representative winding threads.

On the vertical axis, numbers (thread numbers) are assigned to one unprocessed wound yarn supplied to the yarn processing machine or five product processed wound yarns obtained in the winding order.

The horizontal axis is the spindle number of the thread processing machine, which indicates a winding unit with 100 spindles on each side.

The shaded area indicates the yarn to be inspected, and the white area indicates the yarn to be inspected.

On the conveying mechanism 8, 100 wound yarns are stacked in one horizontal row.

The inspection shall be a dyeing characteristic test, which will be judged in conjunction with other quality information and divided into two categories: pass and fail, or dark dyeing,
They are divided into four categories: medium-dyed, light-dyed, and kakugai.

In the case of Fig. 5, only winding numbers 1, 3, and 5 are inspected, and thread numbers 2 and 4 are not inspected.

For thread numbers 2 and 4, if the inspection results of the previous and succeeding thread numbers match, they will be placed in the same category.If they do not match, or if there is other quality information such as an abnormality in processing conditions, the relevant The thread with thread number 2 or 4 on the weight is also inspected.

The collection and transportation of winding yarn in the case of such inspection and sorting logic will be described.

That is, the collection and transportation of the yarn after the raw material to be supplied to the thread processing machine is replaced with a new one by the spindle of the winding unit 10Q and the operation of the thread processing machine is started will be described.

In other words, after stopping the thread processing and switching the thread to be supplied to the thread processing machine for all 100 spindles, the winding thread of thread number 1 is wound up, and any number of threads until the thread number 3 is doffed. At the time of , the yarn is conveyed to the inspection and sorting line via the pool line, inspected and sorted in the same way as in the case of the total inspection explained in FIG. distributed to.

■ Winding number 2 is from just before doffing of winding number 3 to winding thread number 4.
Before the fish are doffed, they are transferred from the individual reserve devices 4 to the carrier 8 and transported to the pool line lay 7a.

■ Winding thread number 3 immediately follows winding thread number 2 to rail 7.
They are transported to line b and inspected and sorted.

(2) When the result of roll number 3 is obtained, the conveying mechanism loaded with roll number 2 pooled on rail 7a is placed on rail 7c to perform sorting.

If a large number of yarns requiring inspection occur in yarn number 2, they are placed on the rail 7b and inspected and sorted.

(2) The winding thread number 4 is pooled on the rail 7a from just before the doffing of the winding thread number 5 to before the doffing of the winding thread number 1 obtained from the next supplied thread.

■ Winding thread number 5 immediately follows winding thread number 4 to rail 7.
Transported to b and inspected and sorted.

■ Sort thread number 4 in the same way as thread number 2 in section ■.

By making full use of the reserve function within the winding machine table in this way, the number of conveyance mechanisms 8 pooled on the pool line rail 7a can be minimized, and the distribution of conveyance mechanisms to each machine table can also be improved. Since it is almost unaffected by the schedule, efficient operation can be achieved by minimizing the number of transport mechanisms 8.

In the case of Fig. 5, it is very important to transport winding thread numbers 2 and 3 and winding thread numbers 4 and 5 at almost the same time, since the winding time for one winding thread in a thread processing machine ranges from several hours to one day. It is effective for

Furthermore, since a pool line is provided before entering the inspection line, the transport mechanism 8 loaded with non-inspected winding yarns can be easily introduced into the inspection line depending on the result of the inspection.

In the case of Fig. 6, only winding thread number 1 is inspected, 2, 3, 4, and so on.
5 is not inspected.

In other words, the supplied thread is considered to have the same physical properties from the surface layer to the inner layer.

When winding thread number 1 is wound up, it is carried to the line of rail 7b and inspected and sorted before winding thread number 3 is doffed.

The threads with other thread numbers are sorted based on the inspection results of the thread number 1 of the weight, unless there is any abnormality in the processing conditions, etc.

If a large number of process abnormal weights occur on the same machine, they are placed on the rail 7b line for inspection and sorting.

In this example as well, the operation density of the doffing machine 6 and the transport mechanism 8 can be planned almost independently due to the role of the reserve device 4 in the machine, and rather the transport mechanism 8 can be used to efficiently use the inspection line and the sorting line. The number of pool line rails 7a may be determined by considering only the following.

The idea of dividing each transport mechanism into inspection and non-inspection is well suited to the inspection logic of this example.

In the case shown in Fig. 7, the waste yarn generated when switching the supplied bobbin yarn is wound onto a bobbin, and when the normal processing state is reached and a certain amount of normal yarn is wound on the surface layer, it is doffed and used for inspection. Make thinly wound thread.

This thinly wound yarn is rolled up to the rail 7 before winding yarn number 2 is doffed.
The surface layer yarn is transported to line b and inspected, and is kept on standby on the conveyor 14 shown in Fig. 4 until the inspection result is obtained, and when the result is obtained, it is discharged and turned into waste yarn.

Winding thread numbers 1 and 5 are sorted based on this result.

If many process abnormalities occur on the same machine, the machine is placed in the line from Ra to Ra 7b for inspection and sorting, as in the case in Figure 6. In this example, before the product winding thread with winding thread number 1 is wound up. Since the inspection results can also be output, there is more freedom in the transportation schedule than in the method of selecting the winding yarn shown in FIG. 5.

As explained above in the embodiments, according to the present invention, the congestion of the doffing schedule does not directly affect the conveyance of the wound yarn, and it is possible to efficiently operate the minimum conveyance mechanism, inspection line, and sorting line. can.

It is also highly compatible with various inspection logics, and is extremely effective in solving difficult problems such as storage of winding yarn awaiting inspection or test results, and tracking of the weight and time at which the winding yarn was produced. It is.
