Abstract

Machine for forming strands of cord, in which the end of the cord is wound around the strand and fitted through the strand. By means of a rope guide 52, the cord is moved to a rope gripper 12, and the cord is then secured. The cord is placed around the winding hooks 1, 3 in long lengths. The winding hooks 1, 3 can rotate and be positioned around shafts which lie in line with one another. Rotation of the winding hooks allows the rope to be wound around the strand with the aid of finger 7. At the end of winding, the cord is placed around hook 16, which pulls the cord through the strand, by the rope guide 52. The cord is melted through on this hook. The rope guide 52 executes an oval movement with the aid of carriage 39 and guide 41. The rope guide 52 can be positioned axially by the movement of table 51. <IMAGE>

Description

Rope winding machine.

The rope winding machine is intended to deliver rope in measured lengths in the form of a skein with the last part of the rope being wrapped around the skein and passed through the skein.

These strands of rope were previously individually measured and wound by hand on a reel and after removal the end is wrapped around the strand and the last piece is pulled through the strand.

The mechanization of these operations proves to be very complex since the rope first has to be laid in long loops and then the end has to be wrapped around and looped through these loops. This requires movements on several axes of rotation with the wire cut at the end of the cycle and then tackled again for the next.

The invention involves a system in which the rope is wound around the ends of two hooks, whereby the hooks themselves can rotate synchronously about axes which are in line with each other. The rope is guided by a guide that moves in an oval path around the hooks and is axially movable. Positioning the hooks has made it possible to prepare strands of the same length completely finished for shipment. The rope is fed continuously from a roll.

The invention is now discussed with reference to the drawing,

Fig. 1 shows the top view of the machine.

Fig. 2 shows the side view of the rope guide.

Fig. 3 shows the drive of the rope guide.

In FIG. 1 winding hook (1) is indicated. This winding hook (1) is mounted on the shaft of the motor (2). Motor (2) drives winding hook (3) which rotates about bearing (4) synchronously by gears (5, 6). A winding hook (1) has a finger (7) which protrudes slightly before the end (8) of the winding hook (1). Wind-up hook (3) has a hook-shaped lug (9) which points towards the interior of the hook near the end <10> of winding hook <3).

A rope gripper (12) with finger (13) with V-shaped notch and finger (14) with appropriate V-shaped elevation is mounted on the frame (11) at the center line of the winding hook end (10). A cylinder (15) with hook (16) attached to the piston rod is arranged in the frame (11) somewhat next to the winding hook (3). An ejection cylinder (17) with ejector (18) is mounted on the frame (11) approximately midway between the winding hooks (1, 3). A cylinder (19) is mounted on the frame (11) which can move the toothed shaft (20) axially against spring pressure. The toothed shaft (20) carries the winding hook (3) with the gear (6) and is mounted in the bearing (4). Attached to the frame (11) is a rotary cylinder (21) with a flange (22) to which is attached a heated cutter (23). The guillotine blade (24) driven with cylinder (25) is positioned with cylinder (27) attached to part (26) of the frame (11). The finished strands (28) are removed from (30) with conveyor belt (29).

At (31) the rope is fed between two V-shaped gripper fingers (33, 34) with operating cylinder (32), then through eye (35) and zigzag along pins (36) through the eye (37) and the hollow shaft (38 ) to carriage (39). The carriage (39) traverses an oval track by means of wheels (40) and guide (41). Blurring (39) is driven by arm (43) attached to hollow shaft (38). In arm (43) is a slot that cooperates with roller (44) of carriage (39). The hollow shaft (38) is driven by motor (46) with chain or timing belt (45),

In FIG. 2 shows the guide unit (47) which is driven by motor (48) and timing belt (49) which can move back and forth with the spindle (50) table (51) with the entire winding mechanism.

A hollow rope guide (52) is mounted on carriage (39) and carries an interchangeable guide nose (54) at the end (53). The guide nose opening (54) is adapted to the rope thickness being processed.

The motors (2, 46, 48) used for this machine are all of the type that can be electronically controlled and are therefore suitable for positioning and holding elements in the correct position or position.

The operation is as follows:

The rope is woven between gripper fingers (33, 34) and through eye (35) and around a number of pins (36), through eye (37), through hollow shaft (38), along arm (43), through rope guide (52) and conducted guide nose (54) until the rope protrudes about 3 centimeters,

The control unit places all elements at the starting position at the start.

The table (51) moves the guide nose (54) forward enough for gripper fingers (13, 14) to grasp the rope end. The table (51) returns to its starting position. The winding hooks (1, 3) rotate approximately 90 degrees with ends (8, 10) pointing downwards so that the rope for hook-shaped ridge (9) comes. The winding hooks (1, 3) return to their starting position. Iu places the rope guide (52, 54) a predetermined number of turns around the winding hooks (1, 3). The rope guide (52, 54) stops in the vicinity of the finger (7) on the winding hook (1). The winding hooks (1, 3) first rotate about 35 degrees with the ends (8, 10) pointing upwards while the rope hooks behind finger (7), after which the rope guide (52, 54) slowly turns and the winding hooks (1, 3 ) spin quickly and wrap the rope around the bundle. The rope guide moves to the starting position, then hook (16) passes through the bundle of rope past the end (10) of the winding hook (3) past the bundle of rope (10). The rope guide (52) makes a turn with the rope around hook (16), this hook (16) is retracted. The rope is then melted with a cutting device (23). Cylinder (19) then presses shaft (20) against spring pressure so that the bundle comes loose from the winding hooks (1, 3) and with tappet (18) the bundle of the winding hooks (1, 3) is pressed and falls on the conveyor belt ( 29).
