Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transferring a bobbin to a bobbin transfer apparatus, and more particularly, in a ring spinning machine or the like, it supplies and conveys empty bobbins to the spindle rows on both sides in the longitudinal direction and discharges them. The present invention relates to a bobbin transfer device for a bobbin transfer device that discharges and conveys a bobbin.

[0002]

2. Description of the Related Art As a conventional bobbin transfer device, an endless belt made of a steel belt or the like is rotatably arranged along a spindle row, and bobbins are inserted into and supported by the endless belt at a pitch equal to the spindle pitch. It is known that a peg is attached. The bobbin inserted into the peg is transferred by rotating the endless belt. Then, a full bobbin on the spindle and an empty bobbin on the peg are exchanged by an automatic pipe changer provided in the spinning machine with the peg and the spindle facing each other. (For example, JP-A-49-54
636, JP-A-50-138, and JP-A-56
See Japanese Patent Publication No. 9431. ) However, in the case where the peg is directly attached to the endless belt as described above, a large tension is applied to the endless belt to stabilize the posture of the bobbin fitted in the peg, and the endless belt is extremely Since it is very long, even if it is used for a long period of time, the endless belt made of steel also stretches. Therefore, there is a problem that the peg spacing that matches the spindle pitch is misaligned, and if automatic pipe replacement is performed in that state, a pipe replacement error occurs, and as a countermeasure, it takes a lot of time and effort to adjust the peg mounting position. There was a problem that it took time.

In order to solve such a problem, for example, Japanese Patent Publication No. 63-35732 discloses a transfer device which does not use an endless belt. That is, a guide rail is arranged along the spindle row, and a large number of peg-equipped trays having a diameter corresponding to the spindle pitch and having a peg on which the bobbin can be fitted are formed in a row along the guide rail. It is disclosed that the transfer mechanism is slidably fitted to the tray and has a transfer mechanism that pushes and moves one group of trays with pegs by locking claws in locking recesses formed on the bottom surface of the tray with pegs.

Further, in Japanese Patent Laid-Open No. 3-124823,
The belt members are attached to the endless belt at a pitch equal to the spindle pitch, and the tray with pegs having pegs into which bobbins can be inserted can be held between the belt members. There is disclosed a peg for temporarily placing an empty bobbin or a full bobbin when performing.
The belt member is slidably supported by the guide rail.

A little more detail will be described with reference to FIGS. 14 to 17. FIG. 14 is an overall schematic plan view showing the ring spinning machine 1
A large number of spindles are provided in parallel on both sides of 01, and an endless belt 102 made of a steel belt is arranged so as to circulate around the spindle with its belt surface vertical. The endless belt 102 is wound between the turning rollers 105, 106, 107 and 108 arranged on the machine ends 103 and 104, and is driven by a drive unit 109.

As shown in FIGS. 15 and 16, belt members 110 are fixed to the endless belt 102 at a pitch equal to the spindle pitch, and adjacent belt members 110, 110.
The tray 111 with pegs is configured to be engaged and held and transferred between them. The tray 111 with pegs is provided with a peg 114 in which a blank bobbin or a full bobbin is fitted and inserted via a collar 113 above a central position of a disk-shaped substrate 112.

The main body of the belt member 110 is the endless belt 1.
02 has a storage opening 115 which is formed in a U-shape having a vertical cross-section that opens in the lateral direction with respect to the traveling direction, and into which the substrate 112 of the peg-equipped tray 111 is fitted. The substrate 11 is attached to the positioning surface 116 at the back of the accommodation opening 115.
2 and the tray 111 with a peg is positioned. A peg 117 for temporarily placing the bobbin is projected upward from the upper surface of the main body of the belt member 110, and a leg portion 118 for coupling with the endless belt 102 is projected downward from the lower surface. The endless belt 102 is sandwiched between the leg portion 118 and the guide member 119, and is fastened and fixed by the fixing screw 120.

As shown in FIG. 17, a guide rail 121 having a generally U-shaped cross-section that opens upward and has a brim formed from the upper end to the outer side is along the moving path of the endless belt 102 along the longitudinal direction of the spinning machine 101. This gadrail 1
The leg portion 118 and the guide member 119 of the strip member 110 are slidably guided between the facing surfaces of the strip 21, and the bottom surface of the main body of the strip member 110 is slidably supported on the upper surface of the collar.

Furthermore, in Japanese Patent Publication No. 3-501506, a holding member having a positioning recess for engaging and holding a tray with a peg on its side surface is attached to an endless belt at a pitch equal to the spindle pitch, and the holding member is provided with a peg. It is disclosed that a suction means for sucking and holding the tray is provided, and a support rail for slidably supporting the tray with pegs is arranged in a spindle row arrangement region in the rotation path of the endless belt.

Further, in any of the bobbin transfer devices using the trays with pegs described above, the transfer when the trays with pegs are supplied to or discharged from the bobbin transfer device are all performed.
It is possible by moving the tray with pegs horizontally.

[0011]

However, the Japanese Patent Publication No. 63-
In the structure of the bobbin transfer device disclosed in Japanese Patent No. 35732, since the outer diameter of the tray with pegs must be equal to the spindle pitch, the tray with pegs must be changed when the spindle pitch of the spinning machine changes. There is. In addition, it is necessary to provide separate transfer mechanisms on the left and right sides of the machine frame of the spinning machine, and to operate them synchronously on the left and right sides, which complicates control and requires a complicated interlocking mechanism. There is a problem. Also, since the tray with pegs is fed in groups (usually 12 to 24 pieces), the load on the tray with pegs is large,
There is a problem that the locking recess and the nail are likely to be damaged. Further, there is also a problem that the pitch between the trays with pegs is easily changed due to the inclusion of cotton wool or lint between the trays with pegs.

Further, in the bobbin transfer device disclosed in Japanese Patent Application Laid-Open No. 3-124823, the tray 111 with pegs is fitted into the accommodation opening 115 of the adjacent belt member 110 and abutted against the positioning surface 116 for positioning. Therefore, there is a problem in that the position of the pegs may be misaligned due to the inclusion of cotton wool or lint. Further, when the spindle pitch of the spinning machine changes, the mounting pitch of the belt member 110 may be changed, but as a result, the position of the positioning surface 116 of the belt member 110 changes greatly, so the peg tray 111 must be changed. There is the problem of not becoming. In addition, the peg 117 is attached to the belt member 110.
Therefore, there is a problem that the bobbin winding diameter of the peg-equipped tray 111 is limited. In addition to the peg tray 111, which is constantly supplied and discharged, the peg 1
Since 17 is projected on the guide rail and is always rotating, there is also a problem that dust, lint, and the like tend to accumulate.

Further, also in the bobbin transfer device disclosed in Japanese Patent Publication No. 3-501506, since the tray with the peg is adsorbed to the positioning recess of the holding member and brought into contact with the positioning recess for positioning, the wind. There is a problem that the position of the tray with pegs may be misaligned due to the adhesion of cotton or lint.

Therefore, in order to solve the above problems, a tray pedestal in which an engaging projection is projected upward is attached to the endless belt, and the tray pedestal is slidable by a guide rail. The tray is provided with positioning recesses to which engaging projections are fitted, and the trays are slidably supported by the guide rails. The tension applied to the endless belt is reduced by this to prevent the endless belt from stretching, and the trays with pegs are placed and supported on each tray pedestal, and the engagement protrusions provided on the tray pedestal support the tray with pegs. A bobbin transfer device can be considered in which the positioning concave portion on the bottom surface is fitted and positioned to prevent the position from being changed due to cotton wool, lint, or the like.

However, in such a bobbin transfer device, since the positioning recess is fitted to the engaging projection protruding upward to perform positioning, the transfer of the tray with the pegs to the bobbin transfer device is moved horizontally. The problem is to provide a transfer device that cannot be performed by operation, and that can transfer stably and reliably with a simple configuration.

An object of the present invention is to provide a bobbin transfer device capable of solving the above problems.

[0017]

If there is no significant play between the 35, the engagement will not be smoothly disengaged, and the fitting portion will be damaged. However, according to the above configuration, the positioning concave portion 35 and the positioning fitting portion of the engaging projection 26 are arranged. Until the engagement of 61 is released, the tray portion 3 of the tray 31 with pegs
Since the 2 moves along the gentle slope portion 64, the inclination angle of the peg-equipped tray 32 becomes small, and therefore the positioning recess 35 is formed.
Even if the play of the positioning fitting portion 61 is reduced, the fitting is smoothly released, and the transfer can be performed smoothly while performing highly accurate positioning.

Further, as described above, it is not a passive measure that the gentle inclination portion 64 is provided and the inclination angle is made as small as possible.
As shown in FIG. 13, although the configuration is somewhat complicated, a means for vertically pulling up the peg-equipped tray 31 to the position where the engagement is released may be provided. In FIG. 13, the inclined rail 3
The tips of 7a and 37b are located above the position of engagement with both sides of the peg-equipped tray 31 supported on the tray holder 25. The position is the positioning recess 3

Is provided at the front part of the tray with an elevating member 65 that moves up and down between the engaging positions of the tray 31 on both sides of the peg tray 31 and the tips of the inclined rails 37a and 37b. Rails 6 that engage with both sides of the
6 is provided. Reference numeral 67 is a cylinder device for moving up and down the lifting member 65.

According to this structure, the elevating member 65 is held with the peg-shaped tray 31 held by the engaging rails 66.
Is lifted until the positioning recess 35 and the positioning fitting portion 61 are disengaged from each other, and then the peg-equipped tray 31 moves the inclined rails 37a, 3a as the engaging projection 26 moves.
Since it is moved along 7b, it is possible to perform transfer smoothly while performing highly accurate positioning.

In the above embodiment, the inclined bobbin transfer device 18 uses the inclined rails 37a and 37b, and the supply bobbin transfer device 19 uses the elevating plates 19a and 19b. By providing the bobbin supply rail 21 with an appropriate means for sending the tray 31 with the pegs in synchronism with the endless belt 22, the inclined rail system can be adopted also on the supply side.
