Description

  The present invention relates to a winding insertion device, and more particularly to a device for winding a thin sheet such as a non-woven fabric used for a filter element or the like and inserting it into an insert.

  Conventionally, when winding a sheet-like material such as a nonwoven fabric, for example, Patent Document 1 discloses a cylindrical member that is elastically deformable in a radial direction, and extends axially to the cylindrical member from an outer peripheral portion. A winding shaft having a slit formed in communication with the inner peripheral portion is set on the winding drive shaft, and after the leading end portion of the supply material is inserted into the slit, winding is performed by rotation of the winding drive shaft. A method for winding a roll-like supply, which rolls the supply around the outer periphery of a cylindrical member by rotating a shaft, is described.

JP 2001-301065 A

  However, if a filter is formed by forming a nonwoven fabric into a roll shape using the method described in Patent Document 1 above, a cylindrical space for a paper tube is formed at the center of the filter. When passing through the central space without passing through the formed filter part, the object to be filtered is discharged without being filtered, and the object to be wound loses the filterability as a filter. .

  Further, in the conventional method as described in the above document, the winding start tip is elastically held, pressed by a pressing member, or positioned between the inner periphery of the winding shaft and the winding drive shaft. In order to remove the material to be wound from the take-up shaft by removing the take-up shaft from the take-up drive shaft, it is necessary to remove the part that holds the tip of the winding start and remove it from the take-up shaft. After winding up an object, it cannot be continuously inserted into the object to be inserted, and there is a problem that it cannot be an efficient automatic insertion device.

  Therefore, the present invention has been made in view of the above-described problems in the prior art, and the wound object does not lose the filterability as a filter, and the wound object is automatically and efficiently obtained. It aims at providing the apparatus which can be wound up and inserted in a to-be-inserted object.

  In order to achieve the above object, the present invention provides a take-up insertion device that winds a belt-like article to be wound and then inserts it into an article to be inserted having a cylindrical space. Two stick-shaped clamping means that can be brought into contact with each other and to be taken apart from each other, and when winding the object to be wound by the clamping means, tension is applied in a direction opposite to the winding direction. A tension applying means and a cylindrical space having an inner diameter that is the same as the winding outer dimension of the wound object, and the wound object wound by the clamping means in the cylindrical space, It is characterized by comprising winding guide means for moving to a position immediately before insertion into the object to be inserted.

  And according to this invention, in order to wind up a to-be-winded object using the two rod-shaped clamping means which can mutually contact and separate, the space after extracting the winding tube like the past is formed. It will not be done. Therefore, the article to be wound does not lose its filterability as a filter.

  In addition, according to the present invention, when the winding is performed, the object to be wound is pressed by the winding guide means and wound around the two rod-shaped holding means. By removing the means from the article to be wound, the article to be wound and the clamping means can be separated. When the two rod-shaped clamping means are removed from the object to be inserted, only the object to be wound remains on the object to be inserted, so that the complicated work required to remove the object to be wound from the take-up tube is unnecessary. Thus, after the winding is completed, the insertion operation can be automatically performed continuously.

  Further, according to the present invention, when the object to be wound is wound by the sandwiching means, the tension is applied in the direction opposite to the winding direction by the tension applying means. It is possible to roll up an object without slack.

  Further, in the winding insertion device, when the article to be wound wound in the cylindrical space of the winding guide means is inserted into the article to be inserted, the sandwiching means is wound around the article to be wound. Rotating means for rotating in the taking direction can be provided. As a result, the same action as that at the time of winding is performed at the winding end of the unwinded object to be wound, and the wound object is inserted into the inserted object in a state of being wound around the clamping means. Fraying of the cutting end can be prevented, and high quality can be ensured.

  In the winding insertion device, the clamping means is configured to move the two pins in a direction close to each other by applying pressure to the two opposing pins and at least one of the two pins. It can be a means.

  Further, in the winding insertion device, the tension applying means has two pins opposed to each other, and the object to be wound is hung between the two pins so as to be opposite to the winding direction. It can be set as the tension | tensile_strength addition means which applies tension | tensile_strength.

  As described above, according to the present invention, the wound object does not lose the filterability as a filter, and the wound object can be automatically and efficiently wound and inserted into the inserted object. A possible winding and insertion device can be provided.

  Next, the operation of the winding / inserting device having the above-described configuration will be described.

  As shown in FIG. 1 (b), the article 1 to be wound is set between two winding pins 11 and two tension bars 17. After the setting is completed, the first linear actuator 14 is operated to lower the pusher 15 and bring it into contact with the take-up pin 11, whereby the take-up object 1 is held between the two take-up pins 11. Further, the rotary actuator 16 is operated to rotate the tension bar 17 by 90 °. As a result, the state shown in FIG. 2 is obtained.

  As shown in FIG. 2, the object 1 to be wound is sandwiched between the winding pins 11, and the object 1 to be wound is pulled by the tension bar 17, thereby applying tension to the object 1 to be wound. Thereby, since the tension | tensile_strength opposite to a winding direction can be added with respect to the to-be-winded object 1 at the time of winding by the winding pin 11, the to-be-winded object 1 is made with respect to the winding pin 11. FIG. It becomes possible to wind without slack.

  Next, the rotating NC motor 5 in FIG. 1C is driven to rotate the rotating shaft 8 and the insertion shaft 10 in the direction of the arrow in FIG. As a result, the article 1 to be wound is wound around the winding pin 11. When the winding is completed, the rotating NC motor 5 in FIG. 1 is stopped. The article to be wound 1 is wound up to a predetermined outer dimension by being wound while being pressed by the pusher 15 and being wound along the inner diameter of the winding guide 13 when being wound.

  In parallel with this, the insert 2 is set on the positioning component 18. The positioning component 18 has a shape adapted to the outer shape of the insert 2 and can position and hold the insert 2 without rattling.

  Next, the rotating NC motor 5 is operated again in the winding direction, and the stage 4 is moved to the inserted object 2 side, and the wound object 1 is inserted into the positioned inserted object 2. At this time, the wound object 1 and the winding guide 13 operate synchronously until immediately before the wound object 1 is inserted into the inserted object 2, and the winding guide 13 is placed on the side surface of the positioning component 18. It comes into contact and stops, and only the article 1 to be wound moves by the stage 4 to a predetermined position in the object 2 to be wound. This moving position can be freely set by controlling the NC motor 3.

  The winding guide 13 is stopped by the linear guide 12 at the side surface position of the positioning component 18 in contact therewith. Thereby, the wound article 1 wound up is guided by the winding guide 13 until just before being inserted into the inserted object 2, and can maintain its outer dimension. When the article to be wound 1 is inserted to a predetermined position of the article to be inserted 2, the operations of the rotating NC motor 5 and the stage 4 are stopped. The reason for rotating the article 1 to be wound during the insertion operation is to prevent the winding end from being frayed.

  After the insertion operation is stopped, the take-up pin 11 is rotated in the direction opposite to the take-up winding several times in order to make it easy to remove the take-up pin 11. As a result, the state shown in FIG. Thereafter, the first linear actuator 7 shown in FIG. 1 is operated to retract only the insertion shaft 10, and the winding pin 11 is extracted from the article 1 to be wound. As a result, the state shown in FIG. After removing the winding pin 11, the stage 4 is operated to return the whole to the original position, and the operation is completed.

  Here, since the outer dimension of the take-up pin 11 is about 0.8 mm, even if the take-up pin 11 is pulled out from the take-up object 1, the take-up pin 11 is pulled out due to the elasticity of the take-up object 1. Is naturally plugged.

  Further, during the winding operation, the control unit (not shown) responds to the change in the winding speed due to the change of the outer diameter of the wound object 1 over time, so that the rotational speed of the rotating NC motor 5 is gradually increased. Is controlled so that it can be wound evenly at a constant speed. Furthermore, when inserting the article 1 to be wound into the article 2 to be inserted, it is possible to eliminate the fraying of the end of the article 1 to be wound by setting the optimum combination of the insertion speed and the rotation speed.

  Next, with reference to FIGS. 4 to 11, an embodiment of the winding / inserting device according to the present invention will be described.

  Next, the rotary NC motor 5 is driven to rotate the rotary shaft 8 and the insertion shaft 10. As a result, the article to be wound is wound around the winding pin 11. When the winding of the article to be wound is completed, the rotating NC motor 5 is stopped. The article to be wound is wound to a predetermined outer dimension by being wound while being pressed by the pusher 15 and being wound along the inner diameter of the winding guide 13 when being wound.

  In parallel with the above operation, the material to be wound is supplied to the object to be inserted 2. The insert 2 is set on the support portion of the belt 26 at the supply position shown in FIG. When the set of the insert 2 is completed, the state shown in FIGS. 7 and 8 is obtained. Next, the motor 22 for rotation of FIG. 6 is operated. Accordingly, the insertion object 2 is conveyed to the insertion position by the belt 24 through the rotation driving unit 23. When the conveyance is completed, the fifth linear motion actuator 26 is operated to lift the object to be inserted 2 on the belt 24 by the first positioning component 27, and together with the second positioning component 28, the objects to be shown in FIGS. The insert 2 is positioned and held. This position is coaxial with the rotary shaft 8.

  When the winding work of the wound object and the conveyance and positioning of the inserted object 2 are completed, the second linear motion actuator 14 of FIG. 4 is operated, the pusher 15 is raised and separated from the wound object 1, The rotary actuator 16 is operated to return the tension bar 17 to the original position.

  Next, the rotary NC motor 5 shown in FIG. 6 is operated again in the winding direction, and the stage 4 is moved to the inserted object side 2 to insert the wound object into the positioned inserted object 2. At this time, the material to be wound and the winding guide 13 operate in synchronization until immediately before insertion, and the winding guide 13 comes into contact with the side surface of the positioning component and stops, and only the material to be wound is inserted 2. The stage 4 is moved to a predetermined position.

  This moving position can be freely set by controlling the NC motor 3. The winding guide 13 is stopped at the side surface position of the positioning component 18 in contact with the linear guide 12. As a result, the wound article to be wound is guided by the winding guide 13 until just before insertion, and the outer dimension can be maintained. When the article to be wound is inserted to a predetermined position of the article to be inserted 2, the operations of the rotating NC motor 5 and the stage 4 are stopped.

  The reason for rotating the article to be wound at the time of inserting the article to be wound is to prevent the winding end from being frayed. After the operation of inserting the article to be wound is stopped, the winding pin 11 is rotated in the direction opposite to the winding direction in order to make it easy to remove the winding pin 11. After the winding pin 11 is rotated, the first linear actuator 7 is operated, only the insertion shaft 10 is retracted, and the winding pin 11 is pulled out from the article to be wound. After removing the take-up pin 11, the stage 4 is operated to return the whole to the original position.
