JPH03279166A - Stack changing device for continuous bobbin setter - Google Patents

Abstract

PURPOSE:To shorten swing arms and the moving directional dimension of spinning bobbins of a stack changing device by shifting the center of the swing arms in stack changing direction while the swing arms are swinging holding the spinning bobbins. CONSTITUTION:A plurality of the spinning bobbins transferred from a fine spinning frame by the peg stands on conveyers of the right and left sides are held by the holder 27 of the head of an inlet side swing arm 14 on the inlet side of a continuous type bobbin setter. At the same time, a plurality of the set spinning bobbins transferred in every peg tray to the outlet side are held by the holder 27 of the head of an outlet side swing arm 14. When both swing arms are rotated at an angle of about 90 degrees, the center of the swing of the inlet side swing arm is shifted to the center of the right and left side conveyers, and the center of swing of the outlet side swing arm is shifted to either the right or left side of a conveyer. As a result, even if the length of a swing arm 14 is substantially shorter than 1/2 of the distance between the right and left conveyers, the swing arm 14 can be changed over by about 90 degrees holding a plurality of spinning bobbins for changing stacking.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides a method for inserting a spinning bobbin wound up by a spinning machine into a continuous bobbin setter device provided on the way to the winding machine. This relates to a reloading device for a continuous bobbin setter that simultaneously unloads multiple spinning bobbins from the belt-type peg conveyor that conveys the spinning bobbins from a spinning machine to each peg stand at the entrance and exit dedicated to the continuous bobbin setter device. be.

(Prior art) The spinning bobbins wound up by the spinning machine are taken out to peg stands provided at equal intervals on the belt, and then conveyed to the winding machine. The spinning bobbins sent in are inserted into a continuous bobbin setter that exists independently of the spinning machine and are set there.

(Problem to be Solved by the Invention) In this case, the spinning bobbins sent in a row from the spinning machine by the left and right belt conveyors are rearranged in accordance with the arrangement of the spinning bobbins in the continuous bobbin setter and transferred. Likewise, when sending spinning bobbins from a continuous bobbin setter to a winding machine, the spinning bobbins must be rearranged from the arrangement in the continuous bobbin setter to the left and right belt conveyors before being transferred. This rearrangement and transfer requires a considerable amount of space in the spinning bobbin feeding direction, which prevents miniaturization of the entire apparatus.

SUMMARY OF THE INVENTION An object of the present invention is to provide a reloading device for a continuous bobbin setter that has a simple structure and can easily reduce the space in the spinning bobbin feeding direction.

(Means for Solving the Problems) That is, the present invention turns a plurality of spinning bobbins sent from a spinning machine on peg stands on left and right conveyors almost at right angles to create a main body of a continuous bobbin setter device. At the same time, the plurality of spinning bobbins that have been set and sent out for each peg tray to the outlet side of the main body are picked up from the peg stand on the peg tray and are moved almost at right angles. In a reloading device for a continuous bobbin setter that is converted and transferred to a peg stand on a conveyor to a winding machine, the center position of the left and right conveyors on the entrance side of the main body of the continuous bobbin setter device and the exit of the main body of the continuous bobbin setter device. A rotating arm that rotates by a motor is attached to a position corresponding to the entrance side on the side so that the center of rotation of the rotating arm can be moved to the rotating direction side of the left and right conveyors while rotating, and at a tip position of the rotating arm. In the reloading device for a continuous bobbin setter, a gripping tool for gripping the spinning bobbin on each of the peg stands is attached so that the peg stand and the spinning bobbin can be attached and detached while the spinning bobbin is being gripped.

(Function) In the continuous bobbin setter reloading device configured as described above, the plurality of spinning bobbins sent from the spinning machine by the peg stand on the left and right conveyors are transferred to the inlet side of the main body of the continuous bobbin setter device. At the end of the conveyor, a plurality of set spinning bobbins are gripped by a gripper at the tip of the rotating arm on the entrance side of the main body, and simultaneously fed out to the exit side of the main body of the continuous bobbin setter device for each peg tray. On the exit side of the main body of the type bobbin setter device,
gripped by a gripper at the tip of the swing arm on the exit side of the main body;
In this state, when both the swing arms rotate approximately at right angles, the center of rotation of the swing arm on the entrance side of the main body moves to the center of the left and right conveyors, and the center of swing of the swing arm on the exit side of the main body moves to the center of the left and right conveyors in the swing direction. move to one side.

As a result, the length of the swing arm is 1 of the distance between the left and right conveyors.
Even if it is significantly shorter than /2, it is possible to change direction almost at right angles and reload while holding a plurality of spinning bobbins.

(Effects of the Invention) As described above, in the case of the present invention, as a result of moving the center of the swivel arm in the transloading direction when the swivel arm rotates while gripping the spinning bobbin, the dimension of the spinning bobbin moving direction of the apparatus can be reduced together with the swivel arm. This has the effect of significantly shortening the length.

(Example) Next, the configuration of an example of the present invention will be described with reference to the drawings.

As shown in Figures 1 and 2, the spinning bobbins 1 from the spinning machine (not shown) are inserted into peg stands 3 arranged at equal intervals on the belt conveyor 2 installed on the left and right sides. and is transferred from the belt conveyor 2 to the peg stand 3 on the peg tray 7 on the entrance side of the main body 6 of the continuous bobbin setter device 5 via the later-described continuous bobbin setter reloading device 4, changing direction almost at right angles and being reloaded,
In addition, the set spinning bobbins 1 from the continuous bobbin setter device 5 sent out to the outlet side of the main body 6 for each peg tray 7 are taken up from the peg stand 3 on the peg tray 7, and are placed in the continuous bobbin setter described below. Via the reloading device 4, the spinning bobbins l are reloaded and conveyed to the peg stand 3 on the conveyor 8 for transporting them to a winding machine (not shown), with the direction changed approximately at right angles.

Next, the third section regarding the continuous bobbin setter reloading device 4 will be explained.
To explain in detail with reference to FIGS. 8 to 8, the center position of the left and right conveyors 2 on the inlet side of the main body 6 of the continuous bobbin setter device 5 and the symmetrical position of the outlet side of the main body 6 of the continuous bobbin setter device 5 with respect to the inlet side. As shown in FIGS. 3 to 5, the timing pulley 1O111 is driven by the motor 9 with a reduction gear.
A swing arm 14 that swings around a support shaft 13 via a timing belt 12 is attached so that the center of rotation of the swing arm 14 can be moved toward the swing direction side of the conveyor 2.8 while swinging.
