The purpose of the present invention is to provide a chain winding device capable of winding a chain to a predetermined size without any problems.

An embodiment of the present invention will be described below in detail with reference to the drawings.

In the chain retracting device 1 shown in the drawing, 2 is a chain supply mechanism, which includes a movable member 5 having a linear guide groove 4 that can receive the chain 3 from one end and discharge it downward, and a movable member 5 that moves the movable member 5 in the front-rear direction. Drive mechanisms 6, 6 for swinging the
It consists of.

The drive mechanism 6 has a pinion 8 attached to a shaft 7 that is rotated forward or reverse by a motor (not shown) or the like, and a rack 9 that meshes with the pinion 8 is inserted into a cylindrical body 11 fixed to a frame 10. A movable member 5 is fixed to a rack 9.
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 plate 13 is fixed to the upper surface of the inlet end 12a, and a pair of narrow plates 14, 14 as guide members are attached to the outlet end 12b of the plate 13 to form a gap into which the chain 3 can fit. A housing groove 15 is formed by opening S, and an outlet 1 opened at the outlet side end 12b is provided in the middle of the housing groove 15.
6 is formed.

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.

Reference numeral 17 denotes a winding head, in which 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 the chain winding pins 21, 21 are inserted into the slits 20, 20, respectively, and the upper and lower nuts 22, 22 are inserted into the slits 20, 20, respectively.
The pins 21, 21 are tightened and fixed to the rotary plate 19 at the same time.

The pins 21, 21 can be adjusted to any desired gap by changing their fixing positions. 23 connects the winding head 17 to the exit side end 1
2b and the inlet side end 12a.The support member 25 is slidably attached to the guide rods 24, 24 fixed to the frame 10 in the front and rear direction. It is configured to be 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.

30 presses the chain 3 wound up by the winding head 17 forward from the inlet side end 12a to straighten it, and also holds the cradle 1.
This is a pressing mechanism for pushing out to the exit side end of No. 2.

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. 34, 34 so as to be slidable left and right, a pressure member 35 is fixed to the tips of the rods 34, 34, and the pressure member 35 is configured to be moved left and right by a cylinder 35a.

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.

Reference numeral 36 denotes a discharge conveyor, and an endless chain conveyor 38 is provided at the bottom of a pair of corresponding rails 37, 37 each having an L-shaped cross section.
, 37, pressure plates 39 are attached at regular intervals to press and transfer the chain 3 moving between the rails 3 and 37.
A notch 40 provided on the side surface of 7 and 37 corresponds to the outlet side end 12b of the pedestal 12.

41 is a shutter for opening and closing the notch 40, and is fixed to a shaft 42 rotatably provided on the frame 10.
The tip of an arm 43 protruding from the shaft is connected to a cylinder 44, and the shutter can be opened and closed by the operation of the cylinder 44.

Reference numerals 45 and 45 designate rollers serving as guide means for guiding the tinnin 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 groove 15, the chain 3 in the guide groove 4 falls into the accommodation groove 15. Thereupon, the movable member 5 is moved back, and then the winding head 17 is moved downward by the operation of the cylinder 29 and moved to the outlet 16 in the middle of the receiving groove 15, and the pins 21, 21 are located on both sides of 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 pin 21 la 21 moves forward while winding the chain 3 in sequence on the upper surface of the pedestal 12 as shown in FIGS. 5A to 5B.

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 2
5 stops, the rotation of the winding head 17 stops, and the winding head 17 is moved upward by the operation of the cylinder 29, detached from the chain 3, and returns 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 chain 3 in the rolled-up state on the pedestal 12 forward, and at the same time, the shutter 41 opens by the action 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 widthwise 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, the chain winding device of the present invention has a winding head rotatably provided above the pedestal on which the chain is placed, with a pair of pins protruding from the bottom surface, and a winding head below the winding head. The structure is such that the pins are located on both sides of the chain that is placed on the top surface of the pedestal in a dynamic state, and both pins are configured to wind up the chain by rotating the winding head. The chain can be wound up by hooking the center part of the chain using the loading head, the chain can be reliably wound up without holding the chain, and the structure of the device is simple.

Moreover, since the chain is rolled up from the center, it is only necessary to rotate the chain enough times to wind up half the length of the chain, and therefore the chain can be rolled up quickly.

Furthermore, by setting the pin spacing appropriately, the chain can be wound to a predetermined size.
