This is a list of data examples.

Before giving a detailed description of each of these figures, as an example of a package processing machine consisting of a plurality of weights, an example of the conveying means and the inspection means from the layout of the drawing combustor plant of FIG. 4 is a layout view of one weight of the drawing combustor of FIG. 6 and 8 will be described the structure and operation of the real quality monitoring means made of a tension sensor and the like, respectively.

In FIG. 4, reference numeral 1 denotes a draw combustor, and 4 denotes a self-propelled carrier vehicle which holds a track on a ceiling side of an STS (sky train system) and supports a carrier 40 which will be described later. (6) is a moving device for conveying a package mounted on a transport vehicle of an STS to a tray, (7) a weight inspection device, (8) a sampling device, (9) a knitting inspection device, ( 10 indicates an automatic warehouse, 11 indicates a warehouse crane, 12 indicates a visual inspection device, and 13 indicates an ID attached to each tray, which corresponds to which weight of the smoke. Labeler for attaching, 14 is a bag holder, 15 is a packing device, 16 is a labeler for indicating the quality of a box-loaded package, and 17 is a sealing device for packing with a plastic film. .

The stretchable combustor 1 releases the yarn feeding package P1 once, and extends and stretches the yarn to the package P2. This draw combustor 1 has a plurality of weights each having a single weight independent auto-elevation device and a tension sensor 35 to be described later, and recognizes and stores actual quality data such as thread tension for each package and stores ten thousand volumes. Package (P) is discharged to the storage arm installed in each weight and temporarily stored. Each weight of the drawing combustor 1 is wound with a constant length of the same four speeds, and a package P having a full pipe is discharged from each weight at a time corresponding to a predetermined length and stored in the storage arm.

Package shutters 39 are provided which simultaneously open the storage arms of each weight of the extension combustor 1 and simultaneously discharge only the package P2 at the tip, and the package shutters 39 are somewhat longer than the time corresponding to the normal length. It works in short time. By operating the package shutter 39 for a time shorter than the time corresponding to the normal length, not only the package but also the semi-volume package can be automatically returned. By discharging the package P2 simultaneously from each weight due to the outside of the machine, the carrier P of the STS is expected to be discharged to the transport vehicle 4 of the STS by simultaneously discharging the package P2 from each weight according to the expectations. The package P2 is placed in the order of each weight according to. Therefore, the package P2 discharged from the drawing combustor 1 in correspondence with the order of the weight is conveyed to the tray moving device 6 of the tray circulation device 20 by the transport vehicle 4 of the STS, and moved to the tray. By doing so, correspondence of the position reversed up to the weight of the stretchable combustor 1 becomes possible.

In the tray circulation apparatus 20, the weight inspection (weight inspection apparatus 7), knitting inspection (sampling apparatus 8 and knitting inspection apparatus 9) and appearance inspection (appearance inspection apparatus) of the package P2 transferred to the tray 12)). The data (inspection data) for each package from these inspection means are transferred to the host computer 73 (see FIG. 1), and combined with data (quality data) relating to the quality of the yarn from the draw combustor 1 described later. The quality judgment of ABC etc. is performed. These quality determinations are recorded in the ID number of the tray where each package is moved. Thereafter, the package P2 is stored in the automatic warehouse 10 in a state corresponding to the quality of the storage place and A B C. In the ID number of the tray of the package P2 in the automatic warehouse 10, the result of the knitting inspection is also recorded by drawing out, and the quality of the package in the automatic warehouse 10 is determined. Then, the package P2 of a predetermined quality is taken out from the automatic warehouse 10, and is carried out through the bag loading device 14, the packing device 15, the labeler 16, and the sealing device 17.

In FIG. 5, the drawing combustor 1 is provided with the feed rollers 24, 28, 30, the heaters 25, 29, the cling plate 26, and the belt type combustor 27. As shown in FIG. The haptic yarn Y drawn out from the yarn feed package P1 by the first feed roller 24 is introduced into the primary heater 25, and is passed through the kling plate 26 and the belt type combustor 27 to the second. It reaches the feed roller 28, and is wound up in the package P2 via the primary heater 29 and the 3rd feed roller 30 again. The twist formed in the belt-type combustor 27 propagates to the first feed roller 24 and is heat-set in the primary heater 25. That is, the upstream side of the belt type combustor 27 is a flammable side, and the downstream side is a sea flammable side. In the stretchable combustor 1, such a unit is used as a single weight, and many of them are arranged in the thickness direction of the additional ground.

The belt type combustor 27 consists of two belts 33 and 34 which are installed to cross each other, and the tension of the haptic yarn Y is a tension sensor 35 provided downstream of this belt type combustor 27. Is detected by The tension sensor 35 measures the decompression tension and adjusts the nip force of the belt type combustor 27 by controlling the contact pressure of the two belts so that this decompression tension falls within a predetermined control range. Further, a thread breaking sensor 36 is provided downstream of the secondary heater 29. Reference numeral 37 denotes a yarn cutter, which cuts the yarn upstream than the first feed roller 24 in conjunction with the detection of the thread breaking sensor 36, Prevent occurrence.

This draw combustor 1 is equipped with a single weight independent type auto lift device. In other words, the ascending work such as replacing the paper pipe used for the combustor and threading is automatically performed for each weight. Then, the package P2 of the full tube is once supported by the storage arm 38, and is simultaneously transported to the carrier 40 constituting the transport vehicle 4 of the STS by opening and closing the package shutter 39. It is conveyed to the tray movement apparatus 6 displayed. In addition, the thread in which the tension abnormality is detected by the tension sensor 35 is cut | disconnected in the middle of package processing, and the semi-wound package is discharged as it is. In addition, even when thread break occurs due to mechanical abnormality, the counter-volume package is discharged as it is. When the winding is stopped in this way, the time when the controller 70 attached to the base of FIG. 1 does not reach the specification with reference to the value of the doping timer 50, that is, the length of the thread in the half-wound package is 1 / In the case of small packages of 10 or less, a lamp or the like is turned on and an operator is notified and the package is urged to be removed. In addition, if there is a package removed by an operator, a void occurs in the order in which the package is taken out from each weight in turn. Thus, the controller 70 automatically assigns identification to the quality data of the removed package based on the value of the doping timer 50 to make it clear that the package does not exist. It is easy to cope with, and there is no difference in quality discrimination by contrasting inspection data such as quality data and appearance based on thread tension.

6 to 8, the tension control mechanism 41 and the winding management mechanism 42 will be described. These are to maintain the tension of the yarn satisfactorily based on the quality data from the tension sensor 35. When the tension of the yarn exceeds the allowable range, the winding of the yarn is stopped, and the semi-wound package is discharged from the combustor as it is. In the present invention, in addition to such an operation, the quality data is stored in the host computer 73 (see Fig. 1) and used for quality determination of the full package P2.

The tension control mechanism 41 controls the contact pressure of the belt type combustor 27 based on the tension sensor 35 provided on the actual running downstream of the belt type combustor 27 and the detected value of the tension sensor 35. And a tension control section 46 for driving the means 45.

As shown in Fig. 8, the tension control section 46 has a target value TO of the actual tension, a target range having an appropriate width (e.g., ± 2gr) above and below, and an upper limit of the allowable limit from the target value TO. A belt type combustor 27 is provided in advance through a contact pressure control means 45 so that a permissible range having a width (e.g., ± 10gr) is input in advance and the decompression tension T falls within this target range Tu <T <Td. To adjust the pressure of the During this control, the abnormal tension extension T outside of the permissible range is detected (T &gt; Tmax, T &lt; Tmin), the tension value and the detection period (the actual length L) are taken up each time. Is input to the winding control unit 47. Further, even when the target range Tu <T <Td is exceeded, the tension value and the detection period M are detected. According to the extent exceeding this target range and the permissible range, the grade of a yarn corresponding to the quality of stretch processing can be discriminated.

The winding control unit 47 of the winding management mechanism 42 is assembled to the controller 70 provided at the base of the combustor together with the tension control unit 46 to control the winding machine 49 of the combustor, By the normal length signal of the doping timer 50 provided in each weight, the package P2 which is made full is raised. Then, the quality of the package P2 in the winding is determined by the information from the tension control unit 46, so that the quality of the package P2 is wound up or raised directly without performing any more winding. That is, in addition to the abnormal tension value, which is the input information, and the abnormal detection period L (L1 + L2 +---), which is a cumulative value of the actual length, the abnormal tension detection frequency (frequency) N is counted, and these are counted. Compared with the allowable rule (passing criteria) set in advance, for example, when the length L of the abnormal tension is 10 m or less, it is judged as a quality, and when L is 10 m or more, it is judged as b quality, The operation command is sent to the drive unit 53 of the autodoper 52 provided in each winding machine 49 and discharged as a half-wound package. Such an abnormal package is taken out by an operator.

In the present invention, of course, the quality can be determined even in the middle of the a quality automatically conveyed. That is, among the a quality in which the thread length L of the abnormal tension is 10 m or less, the same quality discrimination can be performed as the a1 quality in which the thread length L of the abnormal tension is 5 m or less and the a2 quality in which 5 m or more and 10 m or less. In addition, it is also possible to determine the quality of a1 quality or a2 quality by adding the thread length M in the case of exceeding the target range Tu <T <Td and the said thread length L. The sea extension tension of the stretch burner is related to the quality of the stretch work process, and the sea extension tension ranks the quality of the yarn of the package, and may be useful for determining the total A, B and C as described below.

The automatic elevating device 52 includes a thread cutting means 54 for cutting the wound yarn Y, and a cradle drive shaft for opening and closing the cradle holding the package P2 back and forth, as well as opening and closing properly. (56), the branch pipe supply drive shaft (59) for raising and lowering the branch pipe stocker (58) for accommodating the known pipe (57), and the threading arm (60) for threading the new branch pipe (57). Consists of. The thread cutting means 54 is installed in the vicinity of the traverse apparatus 61 of the winding machine 49, and as shown in FIG. 7, it holds the thread-mounting groove | channel 63 provided with the blade 82. As shown in FIG. It consists of the cutter 64 and the actuator (not shown in the figure) for raising the cutter 64 to the height of a dead road. In response to the command of the winding control unit 47, the actuator lifts the cutter 64 to capture and cut the processing yarn Y in the traverse. The cut processing yarn (Y) is supported by the acker (65) provided at the front end of the traverse device (61), is pulled to the end of the branch pipe by the turning of the threading arm (60) after the branch pipe exchange is carried out do. In addition, after cutting the thread, the cradle 55 reaches the rear by the turning operation of the cradle drive shaft 56, and the cradle 55 is opened so that the receiving portion provided at the rear of the winder 49 The package P2 is discharged | emitted by the part (illustration omitted from drawing). Subsequently, when the branch pipe stocker 58 descends and grips the new branch pipe on the cradle 55, the cradle 55 is reached forward until it contacts the friction roller 66 by the drive shaft 56 for the cradle, thereby winding up a new branch. Will be started.

Reference numeral 36 denotes a thread breaking sensor, which is raised even when thread breaking occurs due to a mechanical abnormality. The raised package is once supported by a storage arm 38 installed on each weight. And based on the command output from the base attachment controller 70 every time shorter than a full winding length length, the package shutter 39 discharge | releases the lead package simultaneously from the weight according to expectation.

1, the block diagram of the package determination system in the package manufacturing conveyance line mentioned above is demonstrated. In FIG. 1, the main apparatus described in FIG. 4 includes a drawing combustor 1, a conveying vehicle 4, a tray moving device 6, a package weighing machine 7, a knitting inspection 9, and a package appearance inspection 9 , The automatic warehouse 10, the labeler 13 is arranged in this order. The package discharged from the drawing combustor 1 follows the order of the weight and is conveyed to the automatic warehouse 10 in the order of the passage. Data relating to the quality of the yarn of the drawing and combustor 1 is input to the controller 70 with the expectation, and data relating to the package of the package weigh scale 7 and the package appearance inspection 12 are sent to the field tooth personal computer 71. Is entered. The STS 4, the tray moving device 6, and the automatic warehouse 10 enable the conveyance in which the conveyance controller 75 matches the ID number of the tray with the exit position of the package. The labeler personal computer 74 for the labeler 13 is for outputting data necessary for labeling. The controller 70 with the base, the field tooth personal computer 71, the labeler personal computer 74, and the transfer controller 75 are connected to the host computer 73 via the main communication network 72. The host computer 73 combines the data for each package from the real quality monitoring means such as the tension sensor 35 and the data for each package from the inspection means such as the package appearance inspection 9. It functions as a means for discriminating quality.

At each end of the drawing combustor 1, there is provided a controller 70 with a base provided with an indicator, a temperature controller, various alarm devices and a machine operation panel for data or conditions required for operation. This base attachment controller 70 processes data relating to the quality of the yarn from the tension sensor 35 of the draw combustor 1, controls the tension of the yarn, and at the time of exit of the package (whichever is possible at any time). Information on whether an object is present) and the quality data are input to the host computer 73 via the main communication network 72.

The on-site tooth personal computer 71 includes data on the weight of the package from the package weighing machine 7, data on the degree of dyeing from the knitting inspection device 9, and the quality of the badness from the appearance inspection device 12. Inspection data such as data relating to the appearance of the package is input. These data are displayed on the field chip personal computer 71, and the output (monitor or output by printout, etc.) at this location is possible. Moreover, it is discharged to the outside of the machine of the extending | stretching combustor 1 by the conveyance controller 75, and it conveys, comparing with the ID number of the tray at the time of placing it in the tray, and is matched with this ID number from the field chip personal computer 71 Various types of data are inputted into the host computer 73 via the main communication network 72.

In this manner, the host computer 73 receives quality data of the yarn from the controller 70 with the base and various data about the package from the field chip personal computer 71. It is possible to output by Thus, for example, the host computer 73 can output the data list as shown in FIG. 3. For each package placed on the tray, it is possible to discriminate the grades such as the type of yarn, dope date and time, machine number, weight number, A B C, and the like. In addition, the host computer 73 stores data of each package stored in the automatic warehouse 10, and can take out the necessary sequence packages by operating the warehouse crane 11.

In addition, as shown in ID No. 144-48 of Fig. 3, the data is discharged from the draw combustor 1 due to abnormal tension or the like into the semi-wound package, and the data regarding the small package having a weight of 1/10 or less is the data without the package. As the indication is attached. By the way, the quality data of the yarn is transferred to the host computer 73 as the other data as production management data. Therefore, the confusion of packages in the case of attaching the quality results based on the tension of the thread after the visual inspection can be avoided.

In addition, as shown in FIG. 2, each attachment is divided into A B C by judging whether or not each data is stored in order. In step # 81, on the basis of the quality data from the tension sensor 35, it is judged whether the tension is in the quality, that is, whether it is suitable for the above-described a1 quality. In the case of the a1 grade, the determination of A or B is performed next, taking into consideration whether the weight is in the grade in step # 82 or whether the appearance is in the grade in steps # 83 and # 84, respectively. On the other hand, as in the case where the quality data of the yarn is not in the quality and is the a2 quality, the judgment of the weight is added in step # 85, the judgment of the appearance in step # 86 and step # 87, respectively, and determination of B or C is performed.

The conveyance controller 75 is based on the instructions from the host computer 73, the field personal computer 71, etc. of the conveying line including the STS 4, the tray moving device 6, the automatic warehouse 10, and the like. Take control. In these conveyance lines, the conveyance controller 75 always knows the ID number of each package, and can output it from the host computer 73 as needed, such as what quality and weight of the package in which conveyance line is. have.

In addition, in the description of the above-described embodiment, the case of the drawing combustor as the package processing machine has been described, but the present invention can also be applied to the case of inspecting a package raised from a plurality of spin-wound machines and putting it in a warehouse. In this case, it is conceivable to attach an outer diameter inspector of the thread to each weight of the spin winder, and to give the order of the quality of the yarn by the existence of the botula.

9 and 10 are block diagrams and floor charts of the package take-out system of the combustor of the present invention, FIG. 11 is a time-dependent variation in package manufacture at each weight, and FIG. 12 is a view of B at the time of opening the package shutter of FIG. It is a state explanatory drawing of the immediately preceding shelf means.

In FIG. 9, as described above, the doping apparatus 52, the shelf means 38, and the package shutter means 39, which are provided at each weight of the draw combustor 1, and the package from each weight are conveyed. The conveying means (the conveying vehicle 4 of the STS, etc.), the controller 70 with the base of the drawing combustor 1, the controller 75 which controls conveyance of the STS, and the controller 70, 75 It consists of a host computer 73. The controllers 70 and 75 and the host computer 73 constitute control means for controlling the system.

The doping apparatus 52 is installed in the winding mechanism 49 of each weight of the drawing combustor 1 (refer FIG. 6). The doping apparatus 52 carries out a package raise when the thread of predetermined length is wound up to a branch pipe and turned into a full winding package, without causing a thread break etc., or when a thread break or tension abnormality generate | occur | produces. In the present invention, a time in which a thread of a predetermined length is wound in a branch pipe and formed into a multi-package package without causing thread breakage or the like is set as a first interval T1, and the first interval T1 is an extension combustor 1 ) Is set in the base attachment controller 70.

The shelf means 38 is provided for each weight (1 to 8), and temporarily stores the package ascending package for each weight (see FIG. 12). The shutter means 39 is provided at the front end, and the first package (packaged packages and small packages) indicated by the thick line can be discharged all at once toward the conveying means (right side from the ground).

The conveying vehicle 4 of the STS as the conveying means conveys the packages (packaged packages and small packages) discharged from the drawing combustor 1 all at once in the next step. A cycle for carrying out the package from the stretchable combustor 1 is set as the second interval T2, and this second interval T2 is set in the controller 75 for the STS.

The present invention is characterized in that the above-described second interval T2, that is, an interval of time during which the shutter means 39 opens and closes, is shorter than the first interval T1. Thereby, the trouble of a worker manually removing the small package which became the all-round package by thread break etc. can be eliminated.

In the floor chart of FIG. 10, the controller 70 of the combustor sets the first interval T1 corresponding to the predetermined length winding up time (step # 1). The first interval T1 may be automatically input from the setting of the operating conditions of the expectations of the host computer 73. Similarly, the controller 75 of the STS serving as the conveying means is set so that the second interval T2 which is the conveying interval is shorter than the first interval T1 (step # 2). The first interval T1 may also be automatically input from the setting of the operating conditions of the expectations of the host computer 73, in which case the ratio of T2 / T1 is the thread break rate that the host computer 73 grasps. In consideration of this, it is automatically calculated and input to the controller (75).

When the operation of the drawing combustor starts (step # 3), the count of the second interval T2 is started. The floor is repeated until the time interval of the second interval T2 is reached (step # 4, NO), and when the time interval of the second interval T2 is reached (step # 4, YES), All the packages are discharged in unison by the operation of the package shutter (step # 5). Then, the discharged package for one row is transferred to the STS serving as the conveying means (step # 6), and conveyed to the tray transfer device of the tray circulation device by the driving drive of the conveyance bogie of the STS (step # 7). The inspection by the operator of the abnormal weight of the combustor is performed until the next conveyance in the meantime (step # 8). The operator checks the on / off of the lamp of each weight of the stretching machine (step # 9). If the lamp is on (step # 9, YES), the small package remaining in the shelf means is taken out (step # 10). With respect to the extracted weight, the lamp is turned off by turning on the reset button (step # 11). When all lamps for the weight of the expected one row are turned off (step # 9, NO), the flow returns to step # 4 and the floor Repeat.

The meaning of setting the second interval T2, which is the transport interval, to be shorter than the first interval T1 of the full-length package formation time of the predetermined length will be explained with reference to FIG. In FIG. 3, T1 indicates the time from the previous full-wave package formation time until the next full-wave package is formed, that is, the second interval. Further, ① to ⑧ indicate the number of each weight.

Fig. 12 shows the lathes of the respective weights (1) to (8) before the shutter means 39 is opened just before B when the package shutter is opened when the respective weights (1) to (8) are operated as shown in the change chart of FIG. The state of the means 38 is shown. As for Chu (①), there is nothing wrong with the Manchurian package. In the weight (2) and the weight (3), one small package is formed between T2. In the weight (④), the small packages are discharged immediately after the all-round package is formed. In the weight (⑤), the two small packages are formed in succession. In the weight (⑥), the two small packages are successively formed. In the weight (⑦), a small package is formed shortly after the all-round package, and in the weight (⑧), the small package is formed a short time after the small package is formed. When the shutter means 39 is opened, only the uppermost part of the shelf means 38, indicated by the thick line, is discharged to the conveying means. Therefore, the packages (10,000 packages and small packages) are completely discharged from the weights (1 to 3) in the shelf means 38 immediately after conveyance, and one small package remains from the weights (4) and 4). In Chuo (⑥), two small packages remain. The present invention relates to a weight (6) in which two or more small packages remain, and emits an alarm lamp (L), and taking out by manual operation of an operator. Conventionally, although the weight (4) and the weight (7) (8) in which one small package remains, manual work of the worker is required, but not required in the present invention. This is because a shortage package may not be formed at the time of the next Japanese discharge, and the small package is discharged and adjusted because the interval between the exports is shortened at all (the short second interval even at the first interval).

Next, an example of such a method of determining the second interval will be described. This method is determined by calculation from the rate of thread break of the expectation.

In a drawing machine having N weights, if thread break occurs once per hour and A small packages are formed, the thread break rate is expressed as A (time / hour x N).

Thread Break Rate A (time / hour XN) Number of pendulums N () Time required for full building (1st interval) H (hours) STS Returns Sn (times) STS return interval (second interval) St

When the thread breaking rate is A (open / hour x N), the small package is formed by A × H (open / N) for one rise (during H time). Thread breakage occurs evenly in each package, and evenly in relation to the diameter of the package so that the total number of packages (including ten thousand packages and small packages) formed for one package rise is included in the following. It becomes like equation.

N () Universal Package + Small Package Σ (A × H) / (A × H + 1) (pieces) Winding up

(Total number of packages) = N + Σ (A × H) / (A × H + 1)

=

= N + A × H / 2 (pcs)

In other words, if the package rises D times at intervals of H time, the package can be (N + A × H / 2) × D (packages). On the other hand, the STS carries N packages at one time. Therefore, if all these packages need to be transported back to the STS, Sn (times) needs to be returned.

N × Sn = (N + A × H / 2) × D (times),

Sn = (N + A × H / 2) × D / N = (1 + A × H / 2N) × D.

On the other hand, when the cycle (second interval) of STS conveyance is set to St, the time required for STS to convey Sn times is St x Sn, during which D times the package rises at H time intervals. As it becomes

St × Sn = D × H (hours)

Therefore, (second interval) is St

St = D × H / Sn = D × H / (1 + A × H / 2N) × D

= H / (1 + A x H / 2N).

Specifically,

Number of weights N = 216 (pieces)

Required time for opening (first interval) H = 6 (hours)

When the thread breakage occurrence rate is 2.5 (times / hour × 216),

Return cycle (second interval) St

St = H / (1 + A × H / 2N)

= 5.8 hours.

The package quality discrimination system according to claim 1 of the present invention not only inspects the weight and appearance of the package, but also classifies the quality of the yarn processed into the package. The precision can be improved.

According to the invention as recited in claim 2, since there is a small package which is not suitable as a product, package data to be withdrawn and removed before reaching the classification system can be distinguished. It is easy to cope without causing confusion with the inspection data after the kneading.

According to the invention as set forth in claim 3, prior to entering the automatic warehouse, the quality of the package processing machine and the inspection data after the package are ranked, and the shipment management of the package corresponding to the total quality is performed. It becomes possible.

According to the invention described in claim 4, since the quality of the package is discriminated based on both data of tension data and inspection data, multi-step evaluation is possible, and each precision is increased.

The package take-out system of the stretching machine according to claim 5 of the present invention shortens the interval for simultaneously carrying out the packages, so that the small packages can be taken out automatically, and the time required for taking out the workers can be almost omitted. have.

According to the invention described in claim 6, since the second interval, which is the transportation interval, is shortened in consideration of the probability of occurrence of thread breakage of the expectation, the decrease in the transportation efficiency due to the shortening of the transportation interval can be minimized.
