Description

  The present invention is applied to weaving of air bags, towels, and the like, and relates to a wholesale weaving control device that removes a woven fabric from a loom for each predetermined weaving amount.

Air bags, towels, etc. are generally produced by so-called off-cut weaving, which is removed from the weaving machine every predetermined weaving amount. After weaving a set weaving amount, a predetermined operation, for example, a cutting off end for cutting. After weaving the cut-off end, we move to weaving towels, etc., which will be the next cut-off, and when the cut-off end reaches the cut-off position on the woven cloth path, in other words, the set weaving amount is reached. When the corresponding end of the woven fabric reaches the cut-off position on the woven fabric path, the operator cuts the woven fabric at the cut-off end portion and removes it from the loom, and attaches a new roll to the loom (patent) Reference 1).
JP-A-9-3749 ([0024] to [0027])

  However, due to time constraints such as operation time and requirements for the next process, there is a case where cutting out is performed early before reaching the set weaving amount. Also, depending on the production lot, if there is a margin in the woven fabric winding diameter at the set weaving amount, the operator may judge the woven fabric winding diameter by visual observation or measurement during weaving. The weaving is continued even after reaching the value, and the weaving amount may be increased more than usual.

  When cutting off with a weaving amount other than that set in this way, the operator needs to wait until the end of the woven fabric corresponding to the desired weaving amount reaches the cut-off position and can be cut off. Yes, productivity and workability deteriorate.

  In addition, when the end portion of the woven fabric corresponding to the set weaving amount reaches the above-mentioned unloading position, the loom is automatically stopped and the set amount of the weaving amount can be changed to a desired weaving amount during weaving. It is considered as one of the measures. In this case, in the next cut-off weaving, it is necessary to return the set amount to the original, and several times until the excess or shortage of the weaving amount is discovered due to human error such as handing over between workers. There is a possibility that the set amount may not be restored to the original, and the production efficiency is lowered including the next process, or the production management is complicated.

  The present invention was created in consideration of the above circumstances, and in the case of wholesale weaving, when the weaving amount is temporarily changed for some reason during weaving, the weaving amount can be changed without impairing workability. At the same time, in cut-off weaving after the next time, the weaving amount is surely maintained without excess or deficiency.

  The present invention measures a weaving amount during weaving, determines whether or not a measured value has reached a set amount, and performs a predetermined operation for inventing when the set value is reached. Assume a loom with a control device.

  The invention of claim 1 is a weaving amount setting device that sets a first set amount and a second set amount as the set amount, and a manual command that outputs a switching command from the first set amount to the second set amount. The weaving weaving control device includes an output device, and after the start of weaving, performs the above determination based on the first set amount, and when the switching command is input before the measured value reaches the first set amount, The determination based on the second set amount is performed, and after the measured value reaches the second set amount, the determination is automatically switched to the determination based on the first set amount.

  Further, in the invention of claim 2, when the time reaches a predetermined value starting from a weaving amount after the measured value reaches the second set amount or a predetermined time after reaching the second set amount, The wholesale weaving control device automatically switches to the above determination based on the first set amount. In addition to measuring the weaving length using a sensor as the weaving amount after the measured value reaches the second set amount, the second set amount is reached based on the total number of steps, taking one rotation of the loom spindle as one step. Thereafter, the weaving amount may be measured, and when the weaving amount reaches a predetermined value, the determination is made based on the first set amount. The predetermined value of the weaving amount after the measured value reaches the second set amount may be set to 0. In this case, the determination is switched to the above determination based on the first set amount at the same time as the measured value reaches the second set amount. In addition, starting from a predetermined time point after the measured value reaches the second set amount, the time may be measured using a timer and switched after the predetermined time. As the predetermined time point, the measured value is set to the second set value. For example, the time when the amount reaches the amount, the time when the measured value reaches the second set amount, and the time when weaving by a predetermined number of steps is used.

  Further, in the invention of claim 3, the predetermined operation for the wholesaler includes outputting a loom stop signal, and the wholesaler weaving control device is at a predetermined time until the loom is restarted by manual operation. Alternatively, at the predetermined time after the restart, the above determination based on the first set amount is automatically switched.

  Furthermore, in the invention according to claim 4, the predetermined operation for the unloading continues the weaving even after the measured value reaches the second set amount, and the woven fabric corresponding to the second set amount of weaving is continued. When the end portion reaches a predetermined position on the woven fabric path, the notification or the loom is stopped. As a notification, a dedicated notification lamp is turned on and blinked, and a loom stop lamp is lit and blinked in the same or different pattern as in a normal stop.

  The second set amount may be set by inputting the second set amount itself, but in the invention of claim 5, the weaving amount setter stores the additional weaving amount in advance, When the switching command is input, a value obtained by adding the additional weaving amount to the measured value at the time of input is set as the second set amount.

  Furthermore, in the invention of claim 6, the loom is provided with a cancel command cancel switch, and the wholesale weaving control device operates when the cancel switch is operated during the above determination based on the second set amount. In the case before the set amount and the second set amount are reached, the judgment is switched to the above determination based on the first set amount.

  Furthermore, in the invention of claim 7, the loom includes a repeat switch for the determination based on the second set amount, and the wholesale weaving control device executes the determination based on the second set amount, and the measured value is set to the second set value. In the weaving after reaching the amount, it automatically switches to the above judgment based on the first set amount, and when the repeat switch is operated until the measured value reaches the first set amount and the second set amount, Switch to the above decision based on quantity.

  According to claim 1, when the command output device is operated and the determination as to whether or not the measured value has reached the set amount is switched to the determination based on the second set amount, When the value reaches the second set amount, the predetermined operation for the countdown is executed, so that the workability of the countdown is ensured as in the case of the determination based on the first set amount. In addition, since the cut-off weaving control device automatically switches to the above determination based on the first set amount after the measured value reaches the second set amount, the first set amount in the subsequent cut-off weaving No work is required to return to the above determination based on the above, and no human error occurs, so that the weaving amount is ensured without excess or deficiency.

  According to claim 2, when the time reaches a predetermined value starting from a weaving amount after the measured value reaches the second set amount or a predetermined time point after the second set amount is reached, the first Since the determination is automatically switched to the determination based on the set amount, the determination based on the first set amount is surely returned.

  According to claim 3, since the determination based on the first set amount is automatically switched at a predetermined time until the loom is restarted or at a predetermined time after the restart, the loom after the loom is restarted In the cut-off weaving, the above determination based on the first set amount is surely performed without requiring a special switching operation by the operator.

  According to claim 4, when the end of the woven fabric corresponding to the second set amount of weaving reaches a predetermined position on the woven fabric path, the notification or the loom is stopped. After switching to determination based on the second set amount by operating, it is possible to perform other work away from the loom, and productivity is improved.

  According to claim 5, the weaving amount setting device stores the additional weaving amount in advance, and when a switching command is input, a value obtained by adding the additional weaving amount to the measured value at the time of input is set second. Since it is set as a quantity, it is not necessary for the operator to set the second set quantity by adding the measured value and the additional weaving quantity, improving workability, and entering a calculation error and a number with a large number of digits. Avoid abnormal weaving amount due to input mistakes.

  According to claim 6, it is possible to return to the determination based on the first set amount by coping with a case where the determination is erroneously switched to the second set amount, and by operating the cancel switch once. Then, after returning to the determination based on the first set amount, it is possible to change the setting of the second set amount by setting a new second set amount. Accordingly, in addition to the function of outputting a command for switching from the first set amount to the second set amount to the command output device, a new command for outputting a switch command from the current second set amount to another second set amount is output. Therefore, it is possible to cope with a change in the desired weaving amount without adding a function. That is, the weaving amount setting device stores the additional weaving amount in advance, and when a switching command is input, a value obtained by adding the additional weaving amount to the measured value at the time of input is set as the second set amount. Even if the second set amount is input and set as the second set amount, the cancel switch is operated to temporarily return to the determination based on the first set amount. Therefore, the desired weaving amount can be changed without adding a new function to the command output device.

  According to the seventh aspect, it is possible to easily obtain the second set amount of weaving amount in the last cut-off weaving.

  FIG. 1 and FIG. 2 show a changeover of whether or not a measured value has reached a set amount and a predetermined operation for the wholesale in the weaving weaving embodiment to which the present invention is applied. It is the figure represented by the time series corresponding to quantity, and shows the time series which progresses toward the left side from the right side of a figure. Fig. 1 shows that after the last cut-off weaving is completed, the cut-off weaving is resumed, and after the weaving machine is automatically stopped by changing the judgment based on the second set amount during the weaving, the next cut-off weaving is resumed. FIG. 2 shows the cut-off weaving that is changed to the determination based on the second set amount during weaving and then returned to the determination based on the first set amount. FIG. 3 shows an example in which the present invention is applied to a towel loom including a loom movement type terry motion device 5 as a loom, and the towel loom baskets 2 and 3, a part of the cloth movement type terry motion device 5, and The winding device is shown. FIG. 4 is a control block diagram of the towel weaving machine, and represents an operation executed by the cut-off weaving control device 19 for the cut-off. 5 to 7 are flowcharts showing a determination procedure based on the weaving amount of the cut-off weaving control device 19 and a predetermined operation procedure for the cut-off, and a part of the operation start operation of the loom by the operator, Represents a checkout operation.

  As shown in FIG. 3, the towel loom sends warp 1 from a warp beam of pile warp and a warp beam of ground warp (not shown) arranged on the upstream side of the warp path, and warp 1 is 綜 絖 2 and 筬 3. Is led to the woven cloth 4 before weaving. A warp 1 (not shown) is beaten, and the warp 1 and the weft become a woven cloth 4. The woven cloth 4 includes a terry motion device 5, an apparel roll 6, and a plurality of winding rolls 6 arranged sequentially along the woven cloth path on the downstream side before weaving. The wound roll 8 is wound up via the presto roll 7.

  The weaving cloth type terry motion device 5 moves the woven cloth 4 in the warp direction at the time of weaving the pile structure to displace the position before weaving, and the position before weaving advances toward the heel 3. At the time of the first pick, the pile warp is loosened in a loop shape with the beating and a pile is formed. One towel 9, that is, a towel 9 having a single unit pattern, more precisely, a towel 9 woven by weaving a unit pattern, usually has a pile structure that is woven by the operation of the terry motion device 5. The terry motion device 5 includes a border structure that is woven in an inoperative state, and the border structure is usually disposed at both ends of the pile structure, but may be disposed between the pile structures in addition to the both ends. . Depending on the unit pattern, one towel 9 may be formed only of a pile structure and may not include a border structure. Weaving of the towel 9 is performed by repeating the weaving based on the 1 unit pattern, using the towel 9 by weaving the 1 unit pattern as 1 unit, that is, 1 towel, with a predetermined weaving amount (the number of weaving). 9 is produced. For the weaving of the towel 9, so-called wholesale weaving is generally performed in which the woven fabric 4 is cut every predetermined amount, that is, every predetermined number of sheets, and removed from the loom. In the cut-off weaving of the present embodiment, the cut-off end 11 is woven subsequent to the end portion 41 of the woven fabric 4 corresponding to the weaving of a predetermined weaving amount, thereby facilitating the cutting operation. The cut-off end 11 is woven based on the cut-off end pattern, and is formed by a border structure or a structure dedicated to the cut-off end different from the border structure, and the terry motion device 5 is woven in an inoperative state. Does not include organizations. In the cut-off weaving of the present embodiment, the cut-off end weaving based on the cut-off end pattern is started after the end portion 41 of the woven fabric 4 is woven by reaching a predetermined weaving amount, and the cut-off end pattern is started. , More precisely, the cut end 11 is woven over the step of forming the cut end pattern with one rotation of the loom spindle 17 as one step, as described in FIGS. The cut-off end 11 is woven by B length adjacent to the end portion 41. Subsequent to weaving of the cut-off end 11, weaving based on the one unit pattern, that is, weaving of the woven cloth 4 that will be the next cut-off, is performed, and as shown in FIGS. In this embodiment, the loom is automatically stopped after weaving from the start of weaving to S step. As a result, the woven fabric 4 based on the single unit pattern is woven by C length, and the loom is automatically stopped during the weaving of the first or plural towels 9. FIG. 3 shows that the weaving amount reaches the set amount and the cut-off end 11 is woven, and after the cut-off end 11, the woven fabric 4 of the 1 unit pattern pattern that will be the next cut-out is woven by a predetermined S step. Later, the loom automatically stops. After weaving the cut-off end 11, the one-unit-pattern pattern woven fabric 4 is woven by a predetermined S step, so that the cut-off end 11 is positioned downstream of the clothing roll 6. The woven fabric 4 is gripped by the clothing roll 6 and the pressed roll 7 on the upstream side of the cut-off end 11, and can be cut at the cut-off end 11 and is prevented from being loosened by cutting. In this embodiment, the number of steps S is set so that the loom is automatically stopped in a state where the cut-off end 11 reaches between the downstream prestoll roll 7 and the fabric winding roll 8, and the cut-off work is set. The workability is improved.

  The woven fabric moving terry motion device 5 shown in FIG. 3 includes a drive device (not shown), a pair of left and right swing levers 12 having a lower end portion as a fulcrum, an intermediate portion connected to the drive device, and one end swings. It includes an interlocking lever 13 connected to an intermediate portion of the lever 12 and a terry roll 14 that is fixed at both ends to the upper end portions of the pair of left and right swing levers 12 and is spanned in the weaving width direction. The other end of the interlocking lever 13 is connected to a swinging lever (not shown) that supports a tension roll (not shown) of the ground warp yarn, and the terry roll 14 and the tension roll are interlocked with each other via the interlocking lever 13 by the driving device. That is, it is driven in the warp direction. Thereby, the woven fabric 4 wound around the terry roll 14 moves in the warp direction together with the terry roll 14. At that time, since the tension roll moves in the same direction as the terry roll 14, the change in the warp path length accompanying the movement of the woven fabric 4 is absorbed. ) Is not caused by the decrease in the ground warp tension, and no excessive tension is applied even if it is moved to the front side (winding side). Displaces reliably in the warp direction.

  Next, control for executing the weaving amount monitoring operation of the wholesale weaving control device 19 will be described based on the control block diagram of the towel loom of FIG. The loom drives a motor 16 according to a command from the loom control device 15, and the motor 16 rotates the loom main shaft 17. The encoder 18 connected to the loom main shaft 17 detects the main shaft rotation angle and outputs the main shaft rotation angle information to the loom control device 15 and the wholesale weaving control device 19.

  The loom control device 15 receives signals from the encoder 18, the pattern pattern setting device 21, the wholesale weaving control device 19, and an opening pattern setting device, a weft insertion pattern setting device, a terry motion pattern setting device, etc. (not shown). . Further, the loom control device 15 drives various devices such as the terry motion device 5 using these input signals.

  The pattern pattern setting unit 21 sets one unit pattern and a cut-off end pattern in the loom control device 15. The loom control device 15 determines that the current step is the last in the pattern based on the current step progress information in the pattern based on the spindle rotation angle information and the information on the number of steps constituting the pattern set by the pattern pattern setting unit 21. The end signal is output to the wholesale weaving control device 19 at every last step of the 1 unit pattern and the wholesale end pattern.

  The cut-off weaving control device 19 measures the weaving amount, determines whether or not the measured value has reached the set amount, and executes a predetermined operation for cut-off when it reaches the set amount. In the present embodiment, as the predetermined operation for the wholesaler, the wholesaler weaving control device 19 outputs a wholesaler end weaving start command to the loom control device 15, and based on the weaving amount after the start of the wholesaler end weaving. This is a series of operations for outputting a loom stop command to the loom control device 15 when it is considered that the cut end 11 has reached the cut-off position on the woven cloth path.

  The set amount that is the determination criterion for the measurement value is set by a weaving amount setting unit 22 connected to the cut-off weaving control device 19. The weaving amount setting unit 22 sets the weaving amount (weaving number, that is, the number of towels) of one unit pattern pattern in the cut-off weaving as the setting amount. The first weaving amount setting unit 23 and the second weaving amount are set. A setting unit 24 is provided.

  The first weaving amount setting unit 23 sets a normal setting amount, that is, a first setting amount, for the weaving amount of the wholesale weaving.

  The second weaving amount setting unit 24 sets a setting amount when the first setting amount is changed based on the operator's judgment or the like, that is, a second setting amount. In the present embodiment, the second weaving amount setting unit 24 includes an input device 25, a storage device 26, and a computing device 27. When the operator inputs one or more sheets to the input device 25 and executes a registration operation, the input number is stored in the storage device 26 as an additional weaving amount, that is, registered. When a switching command is input from the command output unit 32 to the second set amount by the operator, the calculator 27 reads the additional weaving amount registered in the storage unit 26 and calculates the second set amount. Then, the second set amount is output to the cut-off weaving control device 19. That is, the arithmetic unit 27 reads the additional weaving amount read out and the current measured value input from the number counter 28 via the wholesale weaving control device 19, that is, the measured value at the time of input of the command from the command output unit 32. (The number of weaving sheets) is added and the calculated value is output as a second set amount to the wholesale weaving control apparatus 19.

  Each time the pattern pattern end signal is input from the loom control device 15 via the cut-off weaving control device 19 in the last step of the unit pattern pattern, the number counter 28 increments the accumulated value held by one. At the same time, the integrated value, that is, the count is output as a measured value to the wholesale weaving control device 19. The cut-off weaving control device 19 determines whether or not the measured value has reached a set amount, and when the measured value reaches the first set amount or the second set amount, A command to start weaving of the connected end 11 is output to the loom control device 15. Further, when weaving of the checkout end 11 is completed, a reset signal is input from the checkout weaving control device 19 to the number counter 28, and the number counter 28 sets the integrated value, that is, the measured value to zero.

  Further, a stop step number setting device 29 and a step counter 31 are connected to the wholesale weaving control device 19. The stop step number setting unit 29 sets the step number S, with one unit pattern pattern weaving step executed after the end of weaving of the checkout end 11, that is, one rotation of the loom spindle 17 as one step.

  When weaving of the cut-off end 11 is completed, that is, at the last step of the cut-off end pattern, a cut-off end termination signal is output from the loom control device 15 to the cut-off weaving control device 19. When the cut end ending signal is input, the cut weaving control device 19 outputs a reset signal to the step counter 31 and resets the integrated value of the step counter 31, that is, the measured value. The cut-off weaving control device 19 grasps one rotation of the loom main shaft 17 based on the main shaft rotation angle information from the encoder 18, that is, one step of weaving, and outputs a pulse signal as a count up signal to the step counter 31 every step. Is output. The step counter 31 integrates the number of weaving steps based on the count-up signal, and outputs the accumulated value as a measurement step number to the cut-off weaving control device 19. The cut-off weaving control device 19 outputs a loom stop signal to the loom control device 15 when the number of measurement steps input from the step counter 31 reaches the step number S set by the stop step number setting unit 29. As a result, the loom is stopped in a state where the cut-off end 11 has reached the cut-off position on the woven cloth path.

  A repeat switch 33, a cancel switch 34, a display 35, and a notification lamp 36 are also connected to the wholesale weaving control device 19.

  The repeat switch 33 is manually operated, and outputs a command to execute the determination again based on the second set amount in the last cut-off weaving to the cut-out weaving control device 19. In the present embodiment, the cut-off weaving control device 19 uses the current cut-off weaving amount as the current cut-off weaving amount regardless of whether the previous cut-off weaving determination is based on the first set amount or the second set amount. It is stored, that is, stored until the end of the cut-off end weaving in the wholesale weaving, and the determination based on the second set amount in the previous cut-off weaving can be executed again by reading out based on the command from the repeat switch 33. Yes. However, the previous weaving amount may be stored only when the determination in the last cut-off weaving is based on the second set amount.

  The cancel switch 34 is manually operated to output a command to cancel the determination based on the second set amount, that is, a command to switch to the determination based on the first set amount to the wholesale weaving control device 19. Based on the command, the cut-off weaving control device 19 switches to the determination based on the first set amount.

  The display unit 35 includes a measured value (the number of weaving so far), a first set amount, a second set amount, an additional weaving amount (registered number) input by the second weaving amount setting unit 24, and a cut-off weaving control. The weaving amount of the last or current cut-off weaving stored in the device 19 is displayed.

  As the weaving machine is automatically stopped at the end of the cut-off weaving, that is, when the cut-off end 11 is woven, and it is considered that the cut-off end 11 has reached the cut-off position on the woven cloth path by the subsequent weaving. Thus, a lighting signal is output from the wholesale weaving control device 19, and the notification lamp 36 is lit or blinks. Further, the notification lamp 36 is automatically turned off in this embodiment, and at the start of the next weaving operation of the weaving weaving weaving control device 19 outputs the turning-off signal or stops the output of the lighting signal. To do.

  Based on the flowcharts of FIGS. 5 to 7, the judgment procedure based on the weaving amount of the wholesaler weaving control device 19 and the predetermined operation procedure for the wholesaler will be described in part including operations and operations by the operator. To do.

  First, the case where only the determination based on the first set amount is executed, that is, the case where there is no switching command or repeat command will be described.

  In STEP 1 shown in FIG. 5, the cut-off weaving control device 19 automatically executes measurement value determination based on the first set amount. When the operator operates the operation start switch, the loom control device 15 drives the motor 16 to rotate the loom main shaft 17 and outputs a cut-off weaving start signal to the cut-off weaving control device 19 for the cut-off weaving control. The device 19 turns off the notification lamp 36 based on the cut-off weaving start signal.

  Subsequently, proceeding to STEP 2, the cut-off weaving control device 19 determines whether or not there is an input of the end signal of one unit pattern. Immediately after the operation is started, the determination is NO, and in the case of NO, this determination process is continued until an end signal of one unit pattern pattern is input. Based on the current step progress information in one unit pattern based on the spindle rotation angle information from the encoder 18 and the information on the number of steps constituting one unit pattern set by the pattern pattern setting unit 21, The loom control device 15 recognizes that this step is the last step in the single unit pattern, and outputs a termination signal of the single unit pattern to the weaving control device 19. As a result, when weaving of one unit pattern is completed, the determination is YES. If YES, the process proceeds to STEP 3 where the cut-off weaving control device 19 outputs a pulse signal to the number counter 28 as a count-up signal. 1 is added to the accumulated number up to that, that is, the count.

  Next, proceeding to STEP4, the cut-off weaving control device 19 determines whether or not a repeat command is input. Since there is no repeat command, the determination is NO. If NO, the process proceeds to STEP 5 and the cut-off weaving control device 19 determines whether or not a switching command is input from the command output unit 32. Since it is an explanation when there is no switching command, the determination is NO. In the case of NO, the process proceeds to STEP11, and whether or not the count of the sheet counter 28, more precisely, the measured value by the sheet counter 28 has reached the first set amount (the first weaving number set in the cut-off weaving). The cut-off weaving control device 19 determines. Since a number greater than 1 is set as the first set amount, the determination is no, and if no, the process returns to step 2 again. While weaving is continued and the processing of STEPs 1 to 5 and 11 is repeated, the measured value of the sheet counter 28 matches the first set amount in STEP 11 and becomes YES.

  In the case of YES, the process proceeds to STEP 31 shown in FIG. 7, and the cut-off weaving control device 19 outputs a weaving start command for the cut-off end 11 to the loom control device 15. Thereafter, the process proceeds to STEP 32, and the cut-off weaving control device 19 determines whether or not a cut-off end signal is input. Immediately after the weaving end 11 starts weaving, this determination is NO, and this determination process is continued. Then, based on the current step progress information in the cut-off end pattern based on the spindle rotation angle information from the encoder 18 and the information on the number of steps constituting the cut-off end pattern set by the pattern pattern setting unit 21, The loom control device 15 outputs the end signal of the cut-off end pattern to the cut-off weaving control device 19. When the termination signal is input, the determination is YES. If YES, the process proceeds to STEP 33 and the cut-off weaving control device 19 outputs a reset signal to the step counter 31. Further, the cut-off weaving control device 19 deletes the storage of the previous cut-off weaving amount (the number of weaving) and stores the measured value by the number counter 28, that is, the current cut-off weaving amount (the number of weaving). A reset signal is output to the sheet counter 28. Further, the loom control device 15 continues the weaving after the end of the cut-off end weaving, and resumes the weaving based on the one unit pattern.

  Thereafter, the process proceeds to STEP 34, where it is determined whether the count of the step counter 31, that is, the number of measurement steps input from the step counter 31, has reached a predetermined step number S set by the stop step number setting unit 29. The weaving control device 19 determines. At the time when weaving of one unit pattern is resumed, this determination is NO, and this determination process is continued. When the number of measurement steps coincides with the number of steps S and the determination is YES, the process proceeds to STEP 35, where a loom stop signal is output to the loom control device 15 and a lighting signal is output to the notification lamp 36. As a result, the loom is stopped in a state where the cut-off end 11 has reached the cut-off position on the woven fabric path, and prompts the operator to carry out the cut-off work by turning on or blinking the notification lamp 36. In addition, the set amount of the cut-off weaving amount that is the determination criterion for the measurement value is set to the first set amount. Since the cut-off weaving amount is already set to the first set amount, the cut-off weaving control device 19 maintains the first set amount as the cut-off weaving amount as it is. Thereafter, the process proceeds to STEP 36, and the loom control device 15 automatically stops the loom. The operator performs a cut-off work, and cuts at the substantially central portion at the cut-off end 11 connected to the end portion 41 of the woven cloth 4 whose weaving amount is the first set amount, and removes the woven fabric 4 from the loom, The cloth winding roll 8 for the next cut-off weaving is mounted on the loom. Next, proceeding to STEP 37, the cut-off weaving control device 19 determines whether or not a repeat command is input. Since the description is for the case where there is no repeat command, the determination is NO. If NO, the process proceeds to STEP 38 to determine whether or not the operation of the loom is started. In the case of NO in STEP 38, the process returns to STEP 37, and the determination process for determining whether or not a repeat command is input is continued. When the next cut-off weaving is started and the operation of the loom is started, the determination is YES in STEP38 and the process is finished.

  Next, FIG. 5 shows a case where the operator operates the command output device 32 and the determination based on the second set amount is executed while the determination of the measurement value is performed based on the first set amount. Returning to STEP 5, the explanation will be given.

  In this case, in STEP 5, it is determined whether or not a switching command is input from the command output device 32. In the case of YES, the process proceeds to STEP 6 and the cut-off weaving control device 19 switches the determination criterion of the measured value from the first set amount to the second set amount (second weaving number in the cut-off weaving) and deletes the switching command. To do.

  Subsequently, proceeding to STEP 7, the cut-off weaving control device 19 determines whether or not a cancel command is input from the cancel switch 34. If the description is continued assuming that the cancel switch 34 is not operated, this determination is NO.

  In the case of NO, the process proceeds to STEP 8 and the cut-off weaving control device 19 determines whether or not the measured value by the number counter 28 has reached the second set amount. Immediately after operating the command output device 32, this determination is NO, and the processing returns to STEP2. If the weaving is continued and the measurement value of the number counter 28 coincides with the second set amount while the processes of STEP 2 to 8 are repeated, the determination of the cut-off weaving control device 19 is YES in STEP 8. In the case of YES, the process proceeds to the above-described STEP 31, and thereafter, the processes of STEPs 32-38 are performed. In STEP 35, the cut-off weaving control device 19 sets the set amount serving as the determination reference of the measurement value to the first set amount, that is, switches from the second set amount to the determination based on the first set amount. Thereafter, the process proceeds to STEP 36, where the loom is automatically stopped, and the worker performs a wholesale operation.

  Note that the determination in step 7 may be YES. For example, when the command output device 32 is operated by mistake, the operator can return to the determination based on the first set amount by operating the cancel switch 34. In addition, after operating the command output device 32 and switching to the determination based on the second set amount, the operator operates the cancel switch 34 when it is desired to change the second set amount. That is, the operator operates the cancel switch 34 to temporarily return to the determination based on the first set amount, and then operates the command output device 32 to switch to the determination based on the new second set amount.

  When the cancel switch 34 is operated in this way, the determination in STEP 7 is YES, and the process proceeds to STEP 9, where the cut-off weaving control device 19 sets the measured value based on the count of the number counter 28 to the first set amount. It is determined whether or not it has been reached. When the measured value has reached the first set amount, the determination is YES, the process proceeds to STEP 31, and the determination cannot be switched to the determination based on the first set amount. For example, when the first set amount is 100 sheets, the additional weaving amount is 15 sheets, and the command output device 32 is operated when the measured value is 95 sheets, the second set amount is 95 sheets + 15 sheets = 110 sheets, It is switched to judgment based on two set amounts. If weaving progresses and the cancel switch 34 is operated when the measured value is 105 sheets, the measured value has reached the first set amount, so that the cut-off weaving control device 19 sets the first cancel command. The instruction to switch to the judgment based on the quantity is invalidated and the process proceeds to the next step. As the next step, the process may proceed to STEP 8 in which the determination based on the second set amount is performed. However, in this embodiment, the process proceeds to STEP 31 on the assumption that the desired weaving amount has already been reached. Output. If the measured value does not reach the first set amount and the determination in step 9 is NO, the process proceeds to step 10, and the cut-off weaving control device 19 switches to the determination based on the first set amount and deletes the cancel command. Thereafter, the process proceeds to STEP 11 and the above-described processing is performed.

  Next, the case where the operator operates the repeat switch 33 during weaving in which the cut-off weaving control device 19 is executing the determination based on the first set amount will be described with reference back to STEP 4.

  While the determination based on the first set amount is being executed, the processes of STEPs 2 to 5 and 11 are repeated. During the repetition, if the repeat switch 33 is operated before the measured value reaches the first set amount, the repeat command from the repeat switch 33, that is, the determination based on the first set amount, makes the second in the last cut-off weaving. A signal for switching to judgment based on the set amount is output. Then, in STEP 4, it is determined whether or not there is a repeat command input from the repeat switch 33.

  In the case of YES, the process proceeds to STEP 21 shown in FIG. 6, and the cut-off weaving control device 19 reaches the previous cut-off weaving amount stored as the second set amount in the previous cut-off weaving control device 19. It is determined whether or not. If the current measured value has reached the previous cut-off weaving amount, if YES, the repeat command becomes invalid and the process proceeds to STEP5. In the case of NO, the process proceeds to STEP 22, and the cut-off weaving control device 19 switches to the determination based on the previous cut-off weaving amount (the number of pieces of weaving) stored in STEP 33 of the previous cut-off weaving, whereby the previous second setting is made. While switching to the judgment based on the amount, the repeat command is deleted.

  After STEP 22, the process proceeds to STEP 23, and the cut-off weaving control device 19 determines whether or not a cancel command is input. In the case of YES, the process returns to STEP 10 in FIG. 5, and the cut-off weaving control device 19 switches to the determination based on the first set amount, and then proceeds to the process of STEP 11. On the other hand, if NO in STEP 23, the process proceeds to STEP 24, and the cut-off weaving control device 19 determines whether or not the measured value input from the number counter 28 has reached the last cut-out weaving amount stored. In the case of NO, the process proceeds to STEP 25, and the cut-off weaving control device 19 determines whether or not an end signal of one unit pattern pattern is input. In the case of NO, this determination process is continued. When the weaving for one unit pattern is finished and there is an input of the end signal of one unit pattern and the answer is YES, the process proceeds to STEP 26, and a pulse signal is output to the number counter 28 as a count up signal. Return.

  While the weaving is continued and the processing of STEPs 23 to 26 is repeated, when the measured value input from the number counter 28 reaches the stored last cut weaving amount, that is, the previous second set amount, STEP 24 It becomes YES and moves to the processing of STEP 31 in FIG. 7 and the cut-off end weaving is started.

  Finally, the cut-off weaving control device 19 executes a determination based on the second set amount, and from the end of the cut-off weaving to the start of the next cut-off weaving, more precisely, in accordance with the output of the loom stop signal. A case where the operator operates the repeat switch 33 after the automatic switching to the determination based on one set amount until the start of the next wholesale weaving will be described with reference to FIG. In STEP 8 of FIG. 5, when the measurement value by the number counter 28 reaches the second set amount and the determination becomes YES, the process proceeds to STEP 31 of FIG. 7 and cut-off end weaving is started. Thereafter, in STEP 33, the previous cut-off weaving amount is erased and the current cut-off weaving amount is stored, whereby the second set amount is stored as the current cut-off weaving amount. Thereafter, the determination is switched to STEP 35 based on the first set amount. After the automatic loom stop in STEP 36, the process proceeds to STEP 37, and after the end weaving weaving is completed, the repeat switch 33 is operated after the automatic switching to the determination based on the first set amount according to the output of the loom stop signal. If so, the determination is yes and the process proceeds to STEP39. In STEP39, by switching to the determination based on the current cut-off weaving amount stored, the determination is switched to the determination based on the current second set amount, and the process proceeds to the end. It starts with a judgment based on two set amounts. When the determination is NO in STEP 37, the process proceeds to STEP 38, and it is determined whether or not the operation of the loom is started. In the case of NO in STEP 38, the process returns to STEP 37, and the determination process for determining whether or not a repeat command is input is continued. When the next cut-off weaving is started and the operation of the loom is started, a determination of YES is made in STEP38 and the process proceeds to the end, and the next cut-off weaving is started based on the determination based on the first set amount.

  A case where the changeover weaving is switched from the first set amount to the determination based on the second set amount will be described based on a time series with reference to FIG. FIG. 1 shows a time series that proceeds from the right side to the left side. The loom uses a woven fabric of one unit pattern pattern as one woven fabric of length A, and the first set amount is N sheets. . When the count of the sheet counter 28, that is, the value measured by the sheet counter 28 is N, and weaving N sheets of woven fabric, weaving of the cut-off end 11 is started by connecting to the end portion 41 of the woven fabric. When weaving for one cut-off end pattern and weaving for a length B, the number counter 28 and the step counter 31 are reset, and weaving of the 1 unit pattern pattern that will be the next cut-off is continued. When weaving for a predetermined number of steps S set by the stop step number setting unit 29 and weaving for a length C, the loom automatically stops, and the notification lamp 36 is lit or blinked. The operator cuts the woven cloth at the end of the cut-off end and performs a so-called cut-off operation of removing it from the loom, and installs a new cloth winding roll 8 on the loom. After that, when the operator operates the operation start switch, the determination based on the first set amount is automatically executed, the 1 unit pattern pattern is repeatedly woven, and the woven fabric having the length A is repeatedly woven. The count value of the number counter 28 increases every time the unit pattern pattern is woven. When the operator inputs 2 to the input device 25 as an additional weaving amount and operates the command output device 32 during weaving of the (M + 1) th sheet, the measured value of the number counter 28 at the time of the operation is M, so M + 2 As the second set amount, the determination is switched to the second set amount. When weaving is performed for M + 2 and the measured value of the number counter 28 is M + 2, weaving of the cut-off end 11 is started.

  Next, with reference to FIG. 2, a description will be given with reference to FIG. 2 of the case where the cut-off weaving is switched from the first set amount to the determination based on the second set amount and then the cancel switch 34 is operated to return to the determination based on the first set amount. To do. It is the same until switching to the determination based on the second set amount with M + 2 as the second set amount, but when the cancel switch 34 is operated during weaving of the M + 2 sheet, the determination is switched to the determination based on the first set amount. Thereafter, the count value of the number counter 28 increases every time the unit pattern pattern is woven.

  In this embodiment, the cutting end 11 is woven by being connected to the end portion 41 of the woven fabric 4 corresponding to the weaving of the first set amount and the second set amount, so that the cutting operation at the time of the wholesale operation is performed. Although it is easy, the cut-off end 11 does not necessarily need to be woven, and is cut at the boundary between the woven fabrics 4 in the two-time cut-off weaving, that is, at the end portion 41 of the woven fabric 4 or in the vicinity of the end portion 41. .

  Further, in this embodiment, when the cut-off end 11 reaches the cut-out position on the woven cloth path, that is, when the terminal portion 41 of the woven cloth 4 reaches the predetermined position on the woven cloth path, the loom Although automatically stopped, the loom does not necessarily have to be automatically stopped. That is, on the woven fabric path, if the end portion 41 is located at a predetermined position and is located downstream of the winding position of the clothing roll 6, the woven fabric 4 is upstream even if it is cut by the end portion 41. It is possible to carry out the wholesale operation while keeping the loom running without causing slack. The operator is informed on the basis of visual confirmation that it is the time for the wholesale to take off from the lighting or blinking of the notification lamp 36 after the end portion 41 reaches a predetermined position on the woven fabric path, and performs an operation of turning off the notification lamp 36. Including the checkout work.

  Further, in this embodiment, the set amount uses the number of sheets for each unit pattern, but a unit of length such as yard or meter may be used. Further, the stop step number setting unit 29 may adopt a method of setting the actual weaving length in addition to the method of setting the step number S. In this case, preferably, the input weaving length is the weft density or the like. Is converted into the step number S and set.

  Further, in the present embodiment, it is detected that the count of the step counter 31 has reached the set step number S, and the judgment is switched to the determination based on the first set amount, and the output of the loom stop signal and the lighting signal of the notification lamp 36 is output. Accordingly, the switching is performed at a predetermined time until the loom is restarted or at a predetermined time after the restart, and the predetermined time is set as the output time of the loom stop signal. However, the timer may be operated in accordance with the output of the loom stop signal, and may be switched after a predetermined time from the output of the loom stop signal. Furthermore, it is automatically switched in conjunction with the manual operation of the restart, or the measurement by the counter or the timer is automatically started in conjunction with the manual operation of the restart. You may switch automatically to the judgment based on the first set amount after weaving or after a predetermined time. Further, in this embodiment, when the weaving amount or time after reaching the second set amount reaches a predetermined value, the determination is automatically switched to the determination based on the first set amount. However, it may be switched before the output of the loom stop signal and the lighting signal. For example, it may be detected that the measurement value of the number counter 28 has reached the second set amount and switched to the determination based on the first set amount. Further, for example, the switching may be performed based on the end signal in the last weft insertion step of the cut-off end weaving. Further, for example, the measurement by the timer is started from the detection time when the second set amount of the measurement value of the number counter 28 is reached, or the detection time of the end signal in the last weft insertion step of the cut-off end weaving, It may be switched after a predetermined time. Furthermore, the execution of the cut-off work may be detected and automatically switched by providing a sensor or a limit switch to detect the attachment / detachment of the cloth winding roll 8 or the like. In any of the above, regarding the switching to the determination based on the first set amount, a special operation only for switching by the operator is not required.

  In this embodiment, the display 35, the input unit 25 of the second weaving amount setting unit 24, the input unit (not shown) of the first weaving amount setting unit 23, the repeat switch 33, the cancel switch 34, and the stop step number setting. The input device (not shown) of the device 29 and the command output device 32 are all provided on the same liquid crystal screen of the operation panel. However, some of these devices may be provided on different liquid crystal screens of the operation panel, or may not be provided on the liquid crystal screen by using commercially available devices.

  Further, in the present embodiment, the second weaving amount setting unit 24 changes the number of sheets input to the input device 25 as the additional weaving amount until the second setting amount is reached during execution of the determination based on the second setting amount. Is possible. However, a predetermined number of sheets may be registered in the storage device 26 as unchangeable. In this case, the input device 25 can be omitted. Further, the number of sheets input to the input device 25 may be set not as the additional weaving amount but as the second set amount itself. In this case, the calculator 27 can be omitted.

  Further, the second weaving amount setting unit 24 may also use the operation signal for registering the number of sheets input to the input device 25 as a command for switching to the determination based on the second setting amount. In this case, the command output device 32 can be omitted.

  Furthermore, in this embodiment, the command output device 32 has only a function of outputting a switching command from the first set amount to the second set amount, but from the current second set amount to another second set amount. A new function for outputting a switching command may be added. When switching from the current second set amount to another desired second set amount, the cancel switch 34 is operated to temporarily return to the determination based on the first set amount, and the command output device 32 is operated. Thus, a method of switching to another desired second set amount can be used without returning to the determination based on the first set amount.

  The number counter 28 and the step counter 31 may be incorporated in the cut-off weaving control device 19 instead of being provided separately from the cut-off weaving control device 19. That is, by executing the program for the operation of the measurement value judgment and the stock removal operation associated with the judgment, the program and a part of the stock removal weaving control device 19 constitute each counter, and the operation of each counter is controlled. This is done in collaboration.
