Definitions

  • the present invention relates to a bobbin changing method in a roving frame and an apparatus for carrying out this bobbin changing method. More particularly, the present invention relates to a bobbin changing method in a roving frame in which full bobbins held on a bobbin wheel of a roving frame, having a top-support-type flyer, are exchanged with empty bobbins suspended by the respective bobbin supporting members which are arranged in advance in upper corresponding positions above the roving frame, and an apparatus for carrying out this bobbin changing method.
  • a bobbin changing apparatus in which an operation of exchanging bobbins is carried out by a bobbin changer capable of running along a machine frame of a roving frame, is disclosed in Japanese Unexamined Patent Publication No. 50-89642.
  • the exchange of bobbins is carried out for each bobbin held by the respective bobbin wheels of the roving frame by one bobbin changing arm moving forward and backward and in the vertical direction.
  • each of two empty bobbins suspended by the respective bobbin supporting members of a transporting apparatus is held and taken out by the bobbin changing arm and placed on the corresponding peg of a bobbin reserving mechanism, and the bobbin reserving mechanism is swung to retreat the empty bobbins to the position where the taking-out of each full bobbins is not disturbed.
  • the full bobbins are then taken out from bobbin wheels by the bobbin changing arm and mounted on the corresponding bobbin supporting members supported by the transporting apparatus, and the bobbin reserving mechanism is returned to the original position and the full bobbins are held by the corresponding bobbin changing arms and fed onto the corresponding bobbin wheels of the roving frame.
  • the bobbin changing arm transfers full bobbins on the respective bobbin wheels of front and rear rows to the bobbin supporting members while maintaining the distance between the front and rear full bobbins as it is, the same distance as that between the full bobbins on the respective bobbin wheels of front and rear rows must be maintained between the bobbin supporting members of the transporting apparatus. If full bobbins suspended by the bobbin supporting members of the transporting apparatus are arranged in a zigzag manner, the automation of a roving bobbin exchange in a spinning frame becomes very difficult.
  • two bobbin changing arms working separately for the front and rear rows of bobbin wheels, are used for full bobbins and empty bobbins, respectively, and independent moving mechanisms are used to cause the respective bobbin changing arms to make forward-backward movements and vertical movements between the respective bobbin wheels of the roving frame and the corresponding bobbin supporting members of a bobbin delivery means. Accordingly, the construction becomes complicated and it is impossible to design the bobbin changing apparatus in a compact form.
  • the basic technical idea for attaining this object is that the unitary cycle of bobbin changing work, consisting of the bobbin changing operation of displacing and exchanging full bobbins and empty bobbins between the respective bobbin wheels of a roving frame and the corresponding bobbin supporting members which are arranged in advance in upper corresponding positions above the roving frame concerned is divided into the step of vertically moving each one of the full bobbins and the corresponding one of the empty bobbins between a bobbin transfer position, which is common for each one of the full bobbins and the corresponding one of the empty bobbins, at the level of the bobbin wheels of the roving frame and a bobbin holding and releasing position of the bobbin supporting member, which is common for the each one of the full bobbins and the respective one of the corresponding empty bobbins, along the same course, except for a part thereof, and the step of transferring the bobbins between the respective bobbin wheels of the roving frame
  • the construction of the bobbin changing apparatus for carrying out this bobbin changing method is greatly simplified and the apparatus can be made compact, and the bobbin changing operation can be performed assuredly and promptly. Furthermore, since in the displacing courses for full bobbins and empty bobbins, the bobbin transferring position and the bobbin holding releasing position of each one of the bobbin supporting members are common to the corresponding full bobbin and empty bobbin, in order to avoid interference in the vertical movements of the full bobbins and empty bobbins, a stand-by position for each empty bobbin is formed in the displacing course for each one of the empty bobbins at a position deviated from a linear course connecting the above-mentioned holding and releasing position and the bobbin transferring position.
  • the bobbins are moved in the state where the upper flange portion of each bobbin is suspended; and where the full bobbins are elevated from their transfer positions to the respective corresponding bobbin holding and releasing positions of the bobbin supporting members and are held by the respective corresponding bobbin supporting members, and where the empty bobbins are received from the bobbin supporting members and are brought down to the above-mentioned respective transfer positions, the bobbins are displaced in the state where each bobbin is held at the bottom thereof.
  • the manner of holding bobbins to be displaced is changed at the above-mentioned respective common bobbin transfer position. Accordingly, in the bobbin changing apparatus of a roving frame according to the present invention, the apparatus height can be effectively reduced, and thus the method according to the present invention contributes greatly to the compactness of the bobbin changing apparatus.
  • the bobbin changing method in a roving frame based on the above-mentioned basic technical concept, according to the present invention, is a bobbin changing method in which the bobbin changing operation of a group of bobbins is carried out by using a bobbin changing apparatus for empty bobbins prepared and arranged in advance at an upper position of the roving frame and full bobbins held on bobbin wheels of the flyer frame.
  • the bobbin changing apparatus After completion of the above-mentioned unit operation for a group of bobbins, the bobbin changing apparatus is displaced along bobbin rails and is located at a position corresponding to bobbin wheels for the subsequent unit operation, and this unit operation is repeated, until the above-mentioned bobbin changing operation is completed for all bobbin wheels of a roving frame.
  • This method is characterized by the following constitutional elements of the invention, that is, the bobbin changing operation is carried out by displacing full bobbins and empty bobbins along the respective bobbin moving courses formed between the positions of bobbin wheels of the roving frame and the corresponding positions for holding bobbins by the respective bobbin supporting members and releasing these bobbins therefrom above the roving frame; a common lower bobbin transfer position is formed in each of the above-mentioned bobbin displacing courses, to which position a full bobbin taken out from a bobbin wheel of the roving frame is carried before this bobbin is displaced to the above-mentioned position for holding by the corresponding bobbin supporting member and empty bobbin previously received from the corresponding supporting member is displaced before this empty bobbin is carried to a such position for mounting the corresponding bobbin wheel of the roving frame, at substantially the same height level as the height of the bobbin wheels within the bobbin changing apparatus; the
  • a bobbin transporting apparatus comprising a plurality of transporting members, each having a plurality of bobbin supporting members for suspending a bobbin is travelled along transporting rail means laid out in the longitudinal direction of the roving frame in the upper portion of the roving frame and is stopped at predetermined positions for carrying out the bobbin changing operation.
  • the pitches of bobbin supporting members are made to correspond with the pitches of bobbin hangers of the creel of a spinning frame. Accordingly, when the operation is carried out in a roving frame in which front and rear rows (two rows) of bobbin wheels are arranged, this two-row arrangement is not in agreement with the one-row arrangement of the bobbin supporting members and the operation is disturbed by this disagreement.
  • a peg bar for full bobbins and a peg bar for empty bobbins are used for moving full bobbins and empty bobbins between the above-mentioned common lower transfer positions and the common upper transfer positions for the respective bobbin supporting members, these two peg bars are moved between the position coinciding to the common lower and upper bobbin transfer positions along the above-mentioned respective displacing courses except an intermediate stand-by position for each peg bar for empty bobbins, a carrying mechanism is used to carry full bobbins and empty bobbins between the respective bobbin wheels of the roving frame and the respective corresponding common lower bobbin transfer positions, the full bobbins received from the respective bobbin wheels of the roving frame are transferred to the respective corresponding peg bar for full
