Definitions

  • the present invention relates to a yarn winding machine and a textile machine.
  • German Published Patent Application No. 102006045237 discloses a yarn winding machine having a plurality of images (i.e., images 21 through 26) which are illuminated depending on a position at which a malfunction is generated. Another button is provided as a malfunction fixing button in the yarn winding machine.
  • Operators operating an automatic winder include an operating worker, who monitors whether or not a winding operation is performed in a good condition and performs simple operations to an operational failure of the winding operation, and a maintenance operating worker, who takes charge of an advanced repair when the yarn winding machine breaks down.
  • the operating worker will be referred to as an average operator and the maintenance operating worker will be referred to as an advanced operator.
  • malfunctions generated in the automatic winder include a malfunction which can be handled by the average operator and a malfunction which can be handled by the advanced operator.
  • the yarn winding machine disclosed in the above-described German Published Patent Application No. 102006045237 controls the images to be illuminated depending on a position at which a malfunction is generated; however, the yarn winding machine does not indicate strictly whether such a malfunction should be handled by the average operator or should be handled by the advanced operator instead. Accordingly, there was a case in which the average operator performed an inappropriate maintenance operation while he/she was not able to recognize accurately whether such a malfunction was the malfunction which he/she should handle or the malfunction which he/she should ask the advanced operator to handle. Therefore, in a structure of the yarn winding machine disclosed in German Published Patent Application No. 102006045237 , a mismatch between the required operation to be performed to the yarn winding machine to fix such a malfunction and the operation performed to the yarn winding machine was generated. Consequently, productivity of the yarn winding machine was decreased.
  • the average operator is required to sufficiently confirm which image is illuminated and to sufficiently recognize a required operation.
  • the illuminating images, which indicate the position at which a malfunction is generated, and the malfunction fixing button are provided separately, there was a case in which the average operator performed an inappropriate maintenance operation to an inappropriate position while he/she was not able to accurately recognize a position at which a malfunction has been generated. Therefore, in the structure of the yarn winding machine disclosed in German Published Patent Application No. 102006045237 , a mismatch between the required operation to be performed to the yarn winding machine to fix a malfunction and the operation performed to the yarn winding machine was generated. Consequently, productivity of the yarn winding machine was decreased.
  • the present invention has been made in view of the above-described points. It is a main object of the present invention to prevent a mismatch between the required operation to be performed to a yarn winding machine to fix a malfunction and the operation performed to the yarn winding machine so as to allow productivity of the yarn winding machine to be improved.
  • a yarn winding machine which unwinds a yarn from a yarn supply source and winds the unwound yarn around a winding bobbin, and which switches from an operating state to a stopped state due to generation of a malfunction
  • the yarn winding machine includes a first abnormal-state-indicating and restarting section and a second abnormal-state-indicating and restarting section.
  • the first abnormal-state-indicating and restarting section is switched from a normal state indication to an abnormal state indication at least when a malfunction has been caused by a yarn supply source, and is switched to the normal state indication and switches the yarn winding machine from the stopped state to the operating state when being operated during the abnormal state indication.
  • the second abnormal-state-indicating and restarting section is switched from a normal state indication to an abnormal state indication at least when a malfunction has been caused by a winding bobbin, and is switched to the normal state indication and switches the yarn winding machine from the stopped state to the operating state when being operated during the abnormal state indication.
  • malfunctions generated in an automatic winder include a malfunction which can be handled by an average operator and a malfunction which can be handled by an advanced operator. Accordingly, when coming across a malfunction of the yarn winding machine during a patrol, the averaged operator determines whether he/she should perform an operation for handling the malfunction or should ask the advanced operator to handle the malfunction depending on a malfunction. Since in the present invention, a malfunction caused by a yarn supply source and a malfunction caused by a winding bobbin are indicated by the first abnormal-state-indicating and restarting section and the second abnormal-state-indicating and restarting section, respectively, the average operator can accurately determine whether or not a malfunction can be handled by him/her.
  • each abnormal-state-indicating and restarting section with functions both to let the average operator recognize a malfunction and to release the stopped state of the operation of the yarn winding machine caused by the malfunction, when intending to restart the operation of the yarn winding machine, the average operator can recognize which one between a yarn supplying bobbin (a yarn supply source) and a winding bobbin has caused the malfunction. Therefore, before restarting the operation of the yarn winding machine, the average operator can ask himself/herself whether or not the operation performed by him/her matches the required operation to be performed to the yarn winding machine to fix the malfunction. Accordingly, since a mismatch between the required operation to be performed to the yarn winding machine to fix the malfunction and the operation performed to the yarn winding machine by the average operator is prevented, productivity of the yarn winding machine is improved.
  • the yarn winding machine is further configured as follows. That is, a position for the first abnormal-state-indicating and restarting section and the second abnormal-state-indicating and restarting section to be arranged corresponds to a running direction of a yarn which has been unwound from the yarn supply source and has been wound around the winding bobbin.
  • the operators can easily recognize which one between a yarn supplying bobbin and a winding bobbin has caused a malfunction.
  • the yarn winding machine further includes a third abnormal-state-indicating and restarting section. That is, the third abnormal-state-indicating and restarting section is switched from a normal state indication to an abnormal state indication when a malfunction in the yarn winding machine has been caused by something other than a yarn supply source and a winding bobbin, and is switched to the normal state indication and switches the yarn winding machine from the stopped state to the operating state when being operated during the abnormal state indication.
  • the average operator calls the advanced operator over to the yarn winding machine.
  • a malfunction caused by a yarn supply source, a malfunction caused by a winding bobbin, and a malfunction caused by something other than a yarn supply source and a winding bobbin are indicated by the first abnormal-state-indicating and restarting section, the second abnormal-state-indicating and restarting section, and the third abnormal-state-indicating and restarting section, respectively. Accordingly, the average operator can determine whether a malfunction is the malfunction which he/she can handle or the malfunction which he/she should ask the advanced operator to handle.
  • each abnormal-state-indicating and restarting section with functions both to let the average operator recognize a malfunction and to release the stopped state of the operation of the yarn winding machine caused by the malfunction, when intending to restart the operation of the yarn winding machine, the average operator can recognize which one among a yarn supplying bobbin, a winding bobbin, and something other than a yarn supplying bobbin and a winding bobbin has caused the malfunction. Therefore, before restarting the operation of the yarn winding machine, the average operator can ask himself/herself whether or not the operation performed by him/her matches the required operation to be performed to the yarn winding machine to fix the malfunction. Accordingly, since a mismatch between the required operation to be performed to the yarn winding machine to fix the malfunction and the operation performed by the average operator is prevented, productivity of the yarn winding machine is improved.
  • the yarn winding machine is further configured as follows. That is, the malfunction indicated by the first abnormal-state-indicating and restarting section include absence of a yarn supply source, and/or the malfunction indicated by the second abnormal-state-indicating and restarting section includes absence of a winding bobbin.
  • the yarn winding machine is further configured as follows. That is, the third abnormal-state-indicating and restarting section is arranged between the first abnormal-state-indicating and restarting section and the second abnormal-state-indicating and restarting section.
  • the third abnormal-state-indicating and restarting section is arranged between the first abnormal-state-indicating and restarting section and the second abnormal-state-indicating and restarting section, the operators can easily recognize the section with a malfunction.
  • the yarn winding machine is further configured as follows. That is, the first abnormal-state-indicating and restarting section is formed to indicate an upstream side of a yarn running direction.
  • the second abnormal-state-indicating and restarting section is formed to indicate a downstream side of the yarn running direction.
  • the average operator can recognize the section with a malfunction more intuitively.
  • a textile machine including a plurality of the yarn winding machines accomplishes the high operational rate.
  • a yarn winding machines include a spooling main body having a yarn supplying section which unwinds a yarn from a yarn supplying bobbin and supplies the yarn, a yarn-process executing section which performs a process on the yarn supplied from the yarn supplying section, and a winding section which winds the yarn processed by the yarn-process executing section into a package; a control section which controls the operation of the spooling main body; and an operation panel which operates the spooling main body.
  • the control section includes a memory section which stores a plurality of characters including at least one character of a letter, a number, or a symbol.
  • an indicating section which displays the plurality of characters stored in the memory section in a way in which the plurality of characters are arranged next to one another in the lateral direction
  • a modification section which modifies at least one of the plurality of characters displayed by the indicating section.
  • the modification section includes a first input section and a second input section, arranged next to each other in the lateral direction, to select a position of at least one of the characters displayed by the indicating section to be modified, and a third input section and a forth input section, arranged next to each other in the longitudinal direction, to modify at least one character among the characters selected by the first input section and the second input section.
  • the input section is provided for selecting at least one character among the plurality of characters to be modified, at least one character among the plurality of characters can be modified through a small number of inputs.
  • a directional characteristic of the left is assigned to the first input section and a directional characteristic of the right is assigned to the second input section; therefore, the operators can intuitively recognize an operating method for making a selection among the plurality of characters arranged next to one another in the lateral direction.
  • a directional characteristic of the upward direction is assigned to the third input section and a directional characteristic of the downward direction is assigned to the forth input section; therefore, the operators can intuitively recognize a modifying method, such as increasing or decreasing a number, or adjusting a position of a letter.

  • the indicating section displays at least one of the letter string, the number string, or the symbol string stored in the memory section, in a way in which such characters are arranged next to one another in the lateral direction.
  • An effect resulted by being capable of selecting one among the plurality of characters including at least one character of a letter, a number, or a symbol to be modified through the above-described small number of inputs is particularly useful when at least one of the letter string, the number string, or the symbol string is handled.
  • the yarn winding machine is further configured as follows. That is, the control section can selectively execute two modes, namely a normal winding mode in which the spooling main body performs a normal winding operation and a maintenance mode in which a component of the spooling main body is being maintained. When the first input section and the second input section are simultaneously pressed, the control section switches an execution mode between the normal winding mode and the maintenance mode.
  • the present invention prevents the execution mode from being switched unintentionally.
  • the yarn winding machine is further configured as follows. That is, the first input section and the second input section are formed in a manner in which pressing the first input section and the second input section is made more difficult than pressing the third input section and the forth input section.

  • the yarn winding machine is further configured as follows. That is, whenever the maintenance mode is selected and at least one of the first input section through the forth input section is pressed, the control section sets a component of the spooling main body to work using a predetermined unit based on at least one of the plurality of characters including at least one character of a letter, a number, or a symbol stored in the memory section, and the pressed input section.

That is, since it is not possible under a normal condition to press the right button 23c and the left button 23d simultaneously without being aware of such simultaneous operation, such a configuration prevents the execution mode from being unintentionally switched.
  • the control section 60 sets a component of the spooling main body 5 to work based on the character string stored in the RAM61 and the pressed button. According to the above-described structure, when maintenance work to the spooling main body 5 is performed, the advanced operator can freely set any component to work.
  • the control section 60 sets a component of the spooling main body 5 to work using a predetermined unit based on the character string stored in the RAM61 and the pressed button.
  • control section 60 may flash the top lamp 23f instead of turning on the top lamp 23f as in S740 illustrated in Fig. 9 .
  • providing variations to an indicating style of the top lamp 23f allows precise instructions to be given to the average operator.
  • the control section 60 may flash the bottom lamp 23g instead of turning on the bottom lamp 23g as in S780 illustrated in Fig. 9 .
  • providing variations to an indicating style of the bottom lamp 23g allows precise instructions to be given to the average operator.
  • variations may be provided to an indicating style of the middle button 23e.
  • the lengths of different yarn supplying bobbins B differ slightly from each other in the longitudinal direction. Accordingly, it is preferable to have the original position of the vertical movement of the unwinding assisting device 9 adjustable depending on the length of the yarn supplying bobbin B in the longitudinal direction. Therefore, in the maintenance mode illustrated in Fig. 10 with the unwinding assisting device 9 as the object of maintenance (S910), a control such as inputting the original position of vertical movement of the unwinding assisting device 9, moving up the original position (S925) by pressing the top button 23a (S920), and moving down the original position (S935) by pressing the bottom button 23b (S930) also becomes effective.
  • the alarm lamp 25 adopts a combination of the blue alarm lamp 29 and the red alarm lamp 30, a green lamp may be used instead of the blue alarm lamp 29.
  • a variety of driving devices such as a motor and an air cylinder can be used, for example.
  • control section 60 switches the execution mode by pressing the right button 23c and the left button 23d simultaneously.
  • control section 60 may, alternatively, switch the execution mode when any one of the right button 23c and the left button 23d is pressed.
  • control section 60 may also switch the execution mode when one of the right button 23c and the left button 23d has been pressed and the other is pressed thereafter.
  • a mode switched from the normal winding mode by pressing the right button 23c and the left button 23d simultaneously is not limited to the maintenance mode.
  • the mode may be switched to a yarn defect sample mode disclosed in Japanese Unexamined Patent Application Publication No. 2004-352465 or an input-output device functional check mode disclosed in Japanese Unexamined Patent Application Publication No. 2003-11254 .
  • the character string such as "E85", "F84” or the like is displayed by the 7-segment indicator 22; however, a string including a combination of letters, numbers, and symbols, such as "*77” or "*7E” is also acceptable. Therefore, the character string is not limited to a string consisting of letters and numbers. Further, a string consisting only of numbers such as "777" or a string consisting only of letters such as "EFG” may also be displayed.
  • the yarn supply source is not limited to the yarn supplying bobbin B.
  • a can or the like in which a sliver supplied to each unit of a spinning frame is accumulated, may be used as a yarn supply source, for example.
  • the illuminating state of the top button 23a, the middle button 23e, or the bottom button 23b has been referred to as the abnormal state indication, and the illuminations stopped state thereof has been referred to as the normal state indication.
  • the indication style of the abnormal state indication and the normal state indication is not limited to the indication style described in the above-described embodiment.
  • the abnormal state indication can be differentiated from the normal state indication by switching the indication style between illuminations of the top button 23a, the middle button 23e, and/or the bottom button 23b and flashing thereof.
  • the abnormal state indication also can be differentiated from the normal state indication by illuminating each of the top button 23a, the middle button 23e, and the bottom button 23b in a different color.
