Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a yarn winding device in which a number of winding units are arranged in rows. More specifically, the present invention relates to a yarn winding device equipped with a reserve device for temporarily storing the yarn wound by a winding unit.

The work of doffing, collecting, and transporting yarn wound by yarn winding devices in silk mills, textile processing factories, spinning factories, etc. involves a large number of yarns, a large weight, and damage if not handled with care. Because it is easy to do, it also places a heavy burden on the workers, so automation equipment that can do it efficiently and accurately has been introduced. However, depending on the type of yarn being produced, it is often sorted based on various inspection results, and it is possible to track which machine, which winding unit, and what number the yarn was doffed. There is a need to collect and transport the goods in this manner. However, in the conventional collection and transportation work of winding yarn, it has been proposed that each machine is loaded with one round of doffed winding yarn on one train-like conveyor, but the doffing work is The schedule and the schedule of conveyance do not necessarily match, and even if it is possible to trace the yarn wound by which winding unit on which machine, if there is a missing take-up weight on the machine, When it is not possible to trace the number of doffed yarn, and the yarn is sorted based on the inspection results,
This method has the drawback that no measures can be taken when a problem occurs in the order of doffing.

The purpose of the present invention is to solve the above-mentioned defects of the prior art, and to provide a reserve device that can reliably collect and transport cargo without disturbing the doffing order even if there is a missing winding unit in one machine. It is an object of the present invention to provide a yarn winding device with which it is easy to trace the winding yarn and it is easy to set up a doffing operation schedule.

In order to achieve the above object, the present invention consists of the following configuration.

That is, in a yarn winding device in which a large number of winding units are arranged in a row so that a large number of yarns are simultaneously wound on each winding unit, a winding unit facing each winding unit, Reserve devices capable of storing at least two threads wound by the winding unit are arranged in a row, and each reserve device is provided with a stopper for controlling storage and discharge of the thread. The present invention is characterized by a yarn winding device configured such that the stoppers of the reserve devices arranged in the row are driven in common.

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

FIG. 1 is a side view showing an example of a yarn processing machine using a yarn winding device according to the present invention, and FIG. FIG. 3 is a plan view showing a moving route.

In FIG. 1, a yarn 2 that has passed through a processing machine 1 that performs yarn processing such as drawing, false twisting, and spinning is wound onto a bobbin 10 by a winding unit 3, which is the main part of a winding device. The doffing from the winding unit 3 is sequentially doffed by an automatic doffing machine 6 that runs along the front of a machine base equipped with a large number of winding units 3 in a row on a platform 5. The wound yarn is transferred to a reserve device 4 provided opposite to each winding unit 3. Each reserve device 4 has a structure in which two or more (at most three) wound 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 is composed of a pair of reserve rails A and A', and is provided at an angle with respect to the horizontal.
The winding unit side is higher and the winding yarn discharge side is lower. The winding threads 10a, 10b are used to lock the winding threads 10a, 10b at predetermined positions of the reserve device.
Stoppers B and B' are provided to support the ends of the paper tube, and the stoppers B and B' are fixed to rods C and C', respectively. By rotating this rod C or C', the winding thread 10a or 10b can be moved to the next position. 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 automatically transferred to the thread storage container 9 of the transport mechanism 8 shown in FIG. Operate rod C to return stoppers B and B' to their original positions. Next, when rod C' is operated as described above, the winding thread 10a moves to the position of the winding thread 10b, and the winding thread 10a moves to the position of the winding thread 10b.
The position 0a is left vacant to ensure a storage position for the next doffed yarn. The reserve device is not limited to the embodiment shown in FIG. 3, but other types such as a conveyor type may also be used.

For one machine, the stoppers corresponding to the individual reserve devices are all operated at the same time. The spools from the same period that were doffed and doffed (hereinafter referred to as spool numbers) are now stored.

In so-called missing spindle winding units that have temporarily stopped producing yarn, the storage position for that yarn number becomes vacant. In addition, if thread breakage occurs due to some trouble during the process, and two or more winding threads have the same winding number due to under-bobbin winding, the order of winding threads may be changed if the extra winding thread is stored in the reserve device. Because it disturbs
Any excess of these should be removed each time. The winding yarn in the outermost storage position on the reserve device 4 is introduced along the back side of the machine via the rail 7 into the transport mechanism 8, where the winding threads with the same winding number on one side of the machine are loaded all at once. It can be done. The conveyance mechanism 8 is provided with a 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. This transport mechanism 8 is adapted to be able to run along the rails 7 by means of an electric vehicle or other suitable traction device 17 as shown in FIG. In Figure 2, doffing machines 6, 6
is rail 1 for doffing machine movement provided separately from rail 7
After being carried to the end of the winding unit rows 11, 11 of the machine to be doffed by the carrier 12 moving on the platform 3, it runs on the platforms 5, 5 while doffing. 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 directly to the 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 is subjected to predetermined logical commands, namely (a) 100% inspection to inspect all the winding yarn, and (b) some of the winding yarns are loaded on the conveyor mechanism 8. A representative inspection in which only the winding yarn is inspected completely, and the winding yarns on other conveying mechanisms 8 are sorted according to the result;
(c) Random sampling inspection in which all yarns on the transport mechanism 8 randomly selected for the purpose of checking the yarn manufacturing process are inspected; (d) Possibility of abnormal yarns being mixed in based on manufacturing process management information In accordance with a command such as a special inspection for inspecting all the wound yarns on a certain conveyance mechanism 8, 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 conveyance mechanism 8 arrives at the inspection and sorting line 7b, the yarn loaded on the conveyance mechanism 8 is moved by rotating the conveyor 14 intermittently in the direction of the arrow to activate the robot 18. The pieces are then transferred one by one to a loading position K on the conveyor.

At this time, the winding yarn sequence on the conveyance mechanism 8 and the winding yarn sequence on the conveyor 14 are made to completely correspond, and the winding yarn sequence on the conveyance mechanism
The vacant seats above are also vacant seats on the conveyor 14. When the thread on the conveyor 14 comes to the exit position L, the thread is automatically taken out. The conveyor 14 further moves to the sample collection position M. 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
The switching device 20 connects the thread end of the standard thread 22 to
The yarn on the side of the standard wound yarn 22 is cut, and surface layer yarns of a fixed length are sequentially connected in series and supplied to the inspection device 21 as samples from the wound yarn on the conveyor. 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. Input the information to the robot 19 one after another, and wind the thread 1 at the N position.
0 are automatically sorted and unloaded onto the sorting conveyor 15. By storing the winding yarn on the conveyor 14 until the test results come out in this way, it is easy to correspond to the winding yarn order and sorting information during sorting, and after unloading from the conveyor 14, individual windings can be There is no need to track the yarn sequence, and only the group management of eight transport mechanisms is required, greatly simplifying the software for subsequent process automation and improving reliability. Also,
No matter when the surface layer threads are collected, the inspection device 21
Even if it becomes necessary to re-collect the sample due to some trouble, the thread remains on the conveyor 14, which is advantageous for collecting the sample again. The wound yarn on the sorting conveyor 15 is conveyed to the next process such as weighing, packaging, and packaging section 16. 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, loading onto the conveyor 14, taking out the yarn, sampling and inspecting the surface layer of the winding yarn,
We have described the case in which the various operations of sorting, stacking and unloading are carried out in parallel, but first the unit inspection lot is loaded, then the yarn is taken out and the surface yarn is collected, and the sample yarn for the collected unit lot is inspected. Once the results are available, an operation method may be used in which sorting, stacking, and unloading is performed for each unit lot. 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 of selecting representative winding threads. On the vertical axis, numbers (thread numbers) are assigned to five product processed threads obtained from one unprocessed thread supplied to the thread processing machine in the order of winding. The horizontal axis is the spindle number of the thread processing machine and indicates a winding unit with 100 spindles on each side. The shaded area indicates the winding yarn to be inspected, and the white area indicates the winding yarn that is not inspected. The conveyance mechanism 8 is loaded with 100 winding threads in one horizontal row. For inspection, a dyeing characteristic test is conducted, which is judged in conjunction with other quality information, and is divided into two categories: pass and fail, or into four categories: dark dyeing, medium dyeing, light dyeing, and non-grade dyeing.

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 subsequent 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, they will be classified as such. Also inspect winding number 2 or 4 of the weight. The collection and transportation of winding yarn in the case of such inspection and sorting logic will be described. In other words, the yarn processing is stopped and the raw material supplied to the yarn processing machine is replaced with a new one by the winding unit 100.
We will describe the collection and transportation of the yarn after the weight has been applied and the yarn processing machine has started operating. In other words, after yarn processing has been stopped and the switching of the yarn to be supplied to the yarn processing machine has been completed for all 100 spindles, the yarn with yarn number 1 is wound up and the yarn with yarn number 3 is doffed at any time. The yarn is transported to the inspection and sorting line via the pool line, where it is inspected and sorted in the same way as in the case of the 100% inspection explained in FIG. .

Winding thread number 2 is transferred from each reserve device 4 to the conveyor 8 and transported to the pool line rail 7a from just before doffing of winding thread number 3 to before doffing of winding thread number 4.

Winding thread number 3 is immediately carried to the line of rail 7b following winding thread number 2, and is inspected and sorted.

When the result of the winding thread number 3 is obtained, the conveyance mechanism loaded with the winding thread number 2 pooled on the rail 7a is put into the rail 7c and sorting is performed. If a large number of yarns requiring inspection occur in yarn number 2, they are placed on the rail 7b and inspected and sorted.

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 is immediately carried to rail 7b following winding thread number 4, and is inspected and sorted.

Sort thread number 4 in the same way as thread number 2 in the 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 done on a doffing schedule. Since the number of transport mechanisms 8 can be minimized, efficient operation can be achieved. 1 for thread processing machine
Since the winding time for one winding thread ranges from several hours to one day, it is very effective in the case of FIG. 5 to transport winding thread numbers 2 and 3 and winding thread numbers 4 and 5 almost simultaneously. In addition, since a pool line was installed before entering the inspection line, the transport mechanism 8 loaded with non-inspection winding yarn
Depending on the test results, it can be easily put into the test line. In the case of FIG. 6, only winding number 1 is inspected, and thread numbers 2, 3, 4, and 5 are not inspected. In other words, it is considered that the supplied thread has almost 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 depending on the role of the reserve device 4 in the machine, and rather the transport mechanism 8 can operate the inspection line and the sorting line efficiently. The number of pool line rails 7a and the number of pool line rails 7a may be determined by considering only the usability. 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 to 5 are sorted based on this result. If many process abnormalities occur on the same machine, the machines are placed on the rail 7b line for inspection and sorting, as in the case of FIG. 6. In this example, the inspection result can be issued before the product winding yarn with the winding yarn number 1 is wound up, so that the degree of freedom in the conveyance schedule is increased more than in the method of selecting the winding yarn shown in FIG. 5. In addition, in the case of the method shown in Fig. 7, thread number 5 in the figure is doffed, a new supply thread is switched, and then a thinly wound thread for inspection is collected and this is doffed. However, since the thinly wound thread for inspection is collected in a short time, if the number of threads stored in the reserve device is one, the thread with thread number 5 transferred from the winding unit to the reserve device should be immediately collected. It is necessary to doff the yarn and transfer it to the pool line rail 7a so that the reserve device can receive the next thinly wound yarn for inspection. However, when the number of yarns stored in the reserve device is two or more as in the present invention, even if the winding yarn number 5 is still stored in the reserve device, the thin winding yarn for inspection collected in a short time can be Since the yarn can be received, it becomes very easy to schedule the operation of the automatic doffing machine.

As described above in the embodiments, the yarn winding device according to the present invention is equipped with the reserve device having the above-described configuration, and therefore exhibits the following excellent effects.

First, since the reserve device can temporarily store the yarn wound by the winding unit, the operation schedule of the transport mechanism must be determined in conjunction with the operation schedule of the automatic doffing machine. There is no complexity, and the operation schedule of the automatic doffing machine and the operation schedule of the transport mechanism can be determined independently. Normally, the time interval between doffing in a winding device ranges from several hours to a day, and since it is operated continuously, the automatic doffing machine must be operated even at night, but the collection and transportation of wound yarn is carried out during the day shift. It is often done. Since the apparatus according to the present invention has a reserve device, the yarn stored on the reserve device only needs to be transported before the next doffing, so the collection and transportation schedule can be concentrated in a specific time period. You can make them do it. The yarn stored in the reserve device installed on each machine is stored accurately in the order of the winding number for each machine, so even if the yarn is wound by the same winding unit, Even if the winding unit becomes temporarily depleted and the winding thread of a specific winding number is missing, it will not be confused with the winding thread that has been doffed afterwards, so it is necessary to classify them based on the inspection results. It is possible to reliably classify products with certain characteristics. Moreover, since the winding yarns having the same winding number stored on the reserve device are stored on the reserve device corresponding to each winding unit, there is no movement between the winding units. Further, since the operations for moving the storage position and discharging the winding threads having the same winding thread number on each reserve device are performed simultaneously by the same driving means, the operation is extremely simple.
