At the retreating return position of the movable member 5, there are provided transfer rollers 4a, 4a for drawing the chain 3 inserted into the guide groove 4 from the right to a predetermined position within the guide groove 4. 12
is a pedestal, and a long plate 13 is fixed to the upper surface of the entrance side end 12a of this pedestal 12 in parallel with the above-mentioned movable member 5, and the exit side of the pedestal 12 opposite to this plate 13 is On the side of the end portion 12b, a pair of narrow plates 14, 14 are formed with a gap S into which the chain 3 can fit, forming an accommodation groove 15 that is longer than the length of the chain 3, and a cradle is provided in the middle of the accommodation groove 15. The central part of the chain 3, which is open to the outlet end 12b of the chain 12, forms a corresponding outlet 16.

Further, the upper surface of the plate material 13 is in contact with the lower surface of the movable member 5 of the supply mechanism 2.

IT is a winding head, and a horizontal rotating plate 19 is attached to the lower end of the vertical axis 18, and slits 20, 20 are provided on both sides of the vertical axis 18 in the rotating plate 19 in a direction perpendicular to the vertical axis 18. The upper ends of pins 21, 21 for winding the chain are inserted into the slits 20, 20, respectively, and the upper and lower nuts 22, 2
2, the pins 21, 21 are tightened and fixed to the rotary plate 19.

The pins 21, 21 can be adjusted to any desired spacing by changing their fixing positions.

23 is a moving mechanism for moving and rotating the winding head 17 between the outlet end 12b and the inlet end 12a;
Front and rear guide rods 24, 2 fixed to the frame 10
4, a support member 25 is slidably attached to the support member 25, and the support member 25 is driven back and forth by a cylinder 26.

The shaft 18 of the winding head 17 passes through the support member 25, and a pinion 27 is attached to the upper end of the shaft 18, while a rack 28 that meshes with the pinion 27 is fixed to the frame 10, so that the movement of the support member 25 is prevented. The shaft 18 is configured to rotate accordingly.

Further, the support member 25 is provided with a cylinder 29 for moving the winding head 17 up and down. Furthermore, regulating plates 25a are fixed to the support member 25, which are located at the front and rear of the winding head 17 to prevent both ends of the chain 3 from swinging around.

Reference numeral 30 denotes a pressing mechanism for pressing the chain 3 wound up by the winding head 17 forward from the inlet side end 12a to straighten it and pushing it out to the outlet side end of the pedestal 12.

This pressing mechanism 30 is configured such that a movable support 32 is slidably attached to guide rods 31, 31 in the front and rear directions fixed to the frame 10, and is driven in the front and rear direction by a cylinder 33.
Rods 34, 34 pass through the movable support body 32 so as to be able to slide left and right, and a pressure member 35 is fixed to the tips of the rods 34, 34, so that the pressure member 35 can be moved left and right by a cylinder 35a. It is something.

The pressing surface on the front side of the pressing member 35 is configured to move in parallel at right angles to the chain feeding direction.

36 is a discharge conveyor, and an endless chain conveyor 3 is installed at the bottom of a pair of corresponding rails 37, 37 each having an L-shaped cross section.
8, and the conveyor 38 is provided with L-shaped rails 37, 3.
Pressure plate 3 for press-transferring the chain 3 that moves between 7 and 7
9 are installed at regular intervals, and the rails 37,
A notch 40 provided on the side surface of 37 corresponds to the outlet side end 12b of the pedestal 12.

Reference numeral 41 denotes a shutter for opening and closing the notch 40, which is rotatably attached to a shaft 42 rotatably provided on the frame 10.
Connect the tip of the arm 43 protruding from the cylinder 44 to the cylinder 44,
The shutter is configured to be opened and closed by the operation of the cylinder 44.

45, 45 are rollers for guiding the chain 3 pulled out from the storage groove 15.

The operation of the chain winding device configured as described above will be explained.

When the chain 3 to be packaged is inserted from the right end into the guide groove 4 of the chain supply mechanism 2 with the pin facing vertically, the chain 3 is drawn to a predetermined position within the guide groove 4 by the transfer rollers 4a, 4a. .

Then, the drive mechanism 6 is actuated to move the movable member 5 forward, and when the guide groove 4 reaches the accommodation grooves 1 and 5, the guide groove 4
The inner chain 3 falls into the accommodation groove 15. Thereupon, the movable member 5 is moved back, and then the winding head 17 moves to the cylinder 29.
It moves downward and moves to the outlet 16 in the middle of the storage groove 15, and the pins 21, 21 on both sides are located on both sides straddling the chain 3.

Then, the support member 25 begins to move forward by the cylinder 26, and at the same time, the winding head 17 moves forward while rotating in the direction of arrow X under the action of the rack 28 and pinion 27.
As the winding head 17 rotates, the pins 21, 21 move forward while winding the chain 3 in sequence on the upper surface of the pedestal 12 as shown in FIGS.

At this time of winding, both ends of the chain 3 are unwound due to the action of inertia, but since the regulating plates 25a, 25a are provided, the surplus force at both ends of the chain 3 is removed and the chain 3 is completely wound up. When winding of the chain 3 is completed, the support member 25
stops, the rotation of the winding head 17 is stopped, and the winding head 17 is moved upward by the operation of the cylinder 29, separated from the chain 3, and returned to its original position.

Then, the pressing member 35 of the pressing mechanism 30 is pressed against the cylinder 3.
After moving to the rear of chain 3 by the operation of 3, cylinder 3
3 moves forward and pushes the wound chain 3 on the pedestal 12 forward, and at the same time, the shutter 41 opens due to the operation of the cylinder 44, and the chain 3 moves forward onto the transfer conveyor 3.
6 onto the rails 37, 37. This pressure member 35
As a result of the pressing operation, the chain 3 is brought into a state in which it is in complete contact with the transverse direction on a plane, and is transferred by pressure on the discharge conveyor 36 by the pressurizing body 39, so that it becomes approximately rectangular in plane and is removed from the discharge conveyor 36. It is discharged and packaged using a suitable packaging device (not shown).

Meanwhile, the pressure member 35 returns to its original position. Thereafter, the chain inserted into the guide groove 4 of the supply mechanism 2 is repeatedly subjected to the same action and is completely wound up into a certain shape and is discharged from the discharge conveyor.

As shown in the above embodiments, according to the chain winding device of the present invention, the central part of the chain received in the storage groove is wound up by the winding head on the cradle. The chain can be reliably wound without having to hold the chain, the device is not complicated, and the winding head can be rotated only a few times, so the chain can be wound quickly.

In particular, in the present invention, since the rolled chain is pressed by a pressing mechanism, it can be corrected into a predetermined shape and then discharged.
