Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bobbin handling device for transferring bobbins such as electric wires.

For example, it is required to rotatably support a bobbin discharged from an automatic winding machine, wind up an electric wire end, then turn the bobbin, and set it on a transport vehicle in a continuous manner. In the prior art, these operations were performed using separate drive sources, resulting in large-scale equipment and poor operating efficiency. SUMMARY OF THE INVENTION An object of the present invention is to provide a bobbin handling device that can easily raise and lower a bobbin, and can therefore efficiently perform operations from an automatic winder to setting it on a transport platform. .

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a bobbin handling device 10 of the present invention.
It is provided with a carriage 18 that runs on the top.

On the floor 12, a conveyor 22 for transporting the bobbin 20 discharged from the automatic winding machine flush with the floor surface and a transport cart 24 for transporting the bobbin 20 to a predetermined position are disposed at left and right positions below the pedestal 14, respectively. A carriage 18 receives bobbins from a conveyor 22 and transfers the bobbins to a transport carriage 24. The carriage 18 is shown in more detail in FIGS. 2 and 3 and includes a frame 28 which runs and is suspended by four wheels 26 which engage the rails 16. The main shaft 30 is supported within a sleeve 32 attached to the center of the frame 28 so as to be vertically movable up and down. The upper end of the main shaft 30 is supported by a bearing 36 at the center of the arm 34 so as to be rotatable about its own axis. The driving source for raising and lowering the main shaft 30 consists of a pair of air cylinders 38 disposed within the frame 28 and having piston rods 38a2 connected to both ends of the arm 34. The arm 34 is provided with a brake 40 that frictionally engages with the upper end surface of the main shaft 30 to prevent the main shaft 30 from rotating normally.
is provided. A lateral arm 42 is fixed to the lower end of the main shaft 30, and a pair of hanging shafts 44 having flanges 44a at the lower ends are suspended from both ends of this arm. A movable frame 46 consisting of a pair of plates with a transverse T-shape in cross section has hanging shafts 4 at both ends.
4 has a collar 48 passing through it, so that this movable frame 46
can move vertically relative to the hanging shaft 44 or main shaft 30, and can move up and down together with the main shaft 30 when the collar 48 engages the flange 44a of the hanging shaft.

The movable frame 46 has protrusions 50 on both ends thereof that are further deformed into a flat shape.
These projecting pieces are attached to the lower end of the frame 28 and have 4
It is received by a pair of receiving members 52. Therefore, when the movable frame 46 is received by these receiving members 52,
The main shaft 30 and the arm 42 can be further lowered relative to the movable frame 46, and the main shaft 30 will rise independently until the flange 44a of the hanging shaft 44 engages with the collar 48, but when it rises further than that, The movable frame 46 also rises all at once.
The height of the receiving member 52 can be adjusted using a screw 52a. A pair of pintles 54 are provided with arms 58 having wheels 56 that slidably engage movable frame 46, and these arms each have a link 6 at the lower end of main shaft 30.
Connected with 0.

Therefore, when the main shaft 30 is further lowered after the movable frame 46 is received by the receiving member 52, the links 60 are aligned with each other (
180 degrees), the pair of pintles 54 move in a direction away from the bobbin 20, that is, in opposite directions. Conversely, when the main shaft 30 rises relative to the movable frame 46, the link 60 rotates about the pivot point on the main shaft 30 so that the angle between them becomes smaller, so the pair of pintles 54 move toward each other. to support the bobbin 20. In this way, when the main shaft 30 further rises, the movable frame 46 also moves the bobbin 2 with the pintle 54.
It rises while supporting 0. Therefore, the frame 28 can be transported along the rails 16 from above the conveyor 22 in FIG. 1 to above the carriage 24. A turning mechanism 62 is provided for turning the bobbin 20 by 90 degrees around the axis of the main shaft 30 when the main shaft 30 moves vertically.
It consists of a spiral groove 64 provided on the outer peripheral surface of the frame 28 and a protrusion 66 that is attached to the frame body 28 and engages in the spiral groove 64.

The spiral groove 64 is provided over 90 degrees and has a vertical extension 64a at its upper end so that the turn ends at 90 degrees. In addition, in order to ensure that this rotation of the main shaft is not performed when the main shaft is ascending, but only when descending, the protrusion 66 is
is attached to the frame 28 via a one-way clutch 68. This one-way clutch 68 consists of a fixed disk 68A fixed to the frame 28 and a movable disk 68B that meshes with the upper surface of the fixed disk 68A, and the protrusion 66 is connected to a sleeve 70 fixed to the movable disk 68B. is fixed to the inner surface of the Therefore, when the main shaft 30 rises, the movable disc 68B is slightly lifted and slippage occurs between the discs 68A and 68B, so the main shaft 30 does not rotate, and when the main shaft 30 descends, the discs 68A and 68B The main shaft 30 pivots along the helical groove 64 while being engaged and substantially fixed to the frame 28 by the downward force applied to the protrusion 66 . In this way,
When the carriage 18 lifts the bobbin 20 from the conveyor 22, the axis of the bobbin remains horizontal as shown in FIG. 0, and its axis is vertical. Incidentally, if the bobbin 20 can be lowered onto the transport carriage 24 with its axis oriented horizontally, the turning mechanism 68 can be omitted. There are cases where it is required to lift the bobbin 20 by lifting the main shaft 30 and then rotate the bobbinon 20 around its axis to wind up the wire end.
For this purpose, the illustrated embodiment is provided with a bobbin drive mechanism 72, as shown in FIG.

This bobbin drive mechanism consists of two drive rollers 78 that are rotatably supported by a pivot frame 76 that is pivotally supported on a stand 74. connected.
Before the pintle 54 lifts the bobbin 20, the bobbin drive mechanism 72 is retracted from the bobbin 20 as shown by the dotted line in FIG.
It is advanced by an air cylinder 80 so as to engage with the collar of. Since the drive roller 78 is connected to a drive source (not shown), the bobbin 20 rotates and the slack ends of the wires are wound up. In FIG. 2, reference numeral 69 is a pin fixed to the arm 42 and fitted into the hole 68a of the fixed disc 68A of the one-way clutch when the main shaft 30 rises. This is for automatically correcting. According to the present invention, as described above, the support and lifting of the bobbin by the pintle and the reverse operation are performed by a single drive source that vertically moves the main shaft, so the entire device is miniaturized and control is easy. Since these operations are performed automatically and in an orderly manner, work efficiency is improved. Further, according to the present invention, operations including supporting, lifting, and rotating the bobbin can be performed using a single drive source, and even complex operations can be performed automatically and in an orderly manner.
