Description

[Detailed description of the invention] The invention provides a method for tying objects to be bound. Regarding the binding machine that tightens and binds wire bundles, its purpose is to bundle, supply and pull back the wire rods. The point is that it can be carried out reliably with a constant conveying force.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 1 and 2, 1 is a conveyor on the carry-in side, and 2 is a conveyor on the carry-out side, each of which is of a two-row parallel type, and the coils to be bound, which are objects to be bound, are simultaneously operated. At the same time as the coils 3 are carried in, the bundled coils are carried out.

Note that the stopping is performed by detecting the coil 3 before bundling.

Reference numeral 4 denotes an elevating and rotating device disposed at the lower part of the center of the binding machine, which raises and lowers the pre-binding coils 3 on the conveyors 1 and 2 and rotates them through a predetermined angle in a lifted state.

Reference numeral 5 denotes a positioning device which stops approximately at the center of the binding machine and positions the unbound Koinobi 3 lifted by the lifting and rotating device 4.

6 is a binding head arranged above one side of the positioning device 5.

Both conveyors 1 and 2, the lifting/lowering rotation device 4, and the positioning device 5 are supported on the machine frame 7 side.

Further, the binding head 6 is held via a bracket 9 on a cart 8 which can be moved into and out of contact with the center A of the binding machine.

This bracket 9 has a feeder 11 for feeding and returning a wire 10, which is a bundled wire material, on the outside of the crotch, and a trolley. 8 is a guide track 12 that guides the wire 10
is provided.

The platform ratio 8 is guided to a rail 14 via wheels 13,
To move it, remove the nut 16, which is screwed onto the threaded rod 15 connected to the rear end of the truck, toward the rail 1.4. This is made possible by rotating the end of 15 with ratchet nod 17.

1 skewer is a wire dispenser provided on the rail 14, and a wire guide 1 that guides the wire 10 without getting tangled.
9 and a constriction part 22 that is fitted onto the wire guide 19 and guides the wire 10 taken out from the droplet coil 20 while constricting it to the center 21 of the tape dispenser, and the wire 10 from this constriction part 22 is guided to the fixture 11 side. The constriction part 22 and the sheave part 23 are supported by a support 24 from the rail 14 side.

Next, details of each part. 6. The lifting and rotating device 4 25 is supported by the support frame 26 from the umbrella frame 7 and the machine frame 7. A pair of guide rods are provided with a cylindrical body 29 guided through a housing 28.

This cylinder 29 is a machine frame. 7 via a bracket 30, and thus the power cylinder 31. By the operation of , it becomes possible to move up and down on the center A of the binding machine.

Reference numeral 32 denotes a rotating shaft inserted through the cylindrical body 29, and is supported by the cylindrical body 29 via a bearing, so that it can rotate about the center A of the binding machine.

The lower end of this rotating shaft 32 is gear-transmitted to a cyclo reducer 33 attached to the cylindrical body 29 side.

Reference numeral 34 denotes a coil receiver attached to the upper end of the rotating shaft 32, which is shaped like a cross in plan view.

This coil receiver section 34 moves up and down so that its surface moves in and out of the conveyor surface, and the raising and lowering moves each cross-shaped arm between both conveyors 1 and 2, as well as between these conveyors 1 and 2. This is done by placing it between two parallel installations.

Positioning Device 5 The positioning device 5 is for centering the unbundled coils 3 that have been brought in, and this is done by pressing the drum-shaped rollers 35 into contact with each other from four directions.

Each drum-shaped roller 35 is attached to a free end of a lever 36, and its base end is fixed to a vertical shaft 38 rotatably supported by a bearing 37.

Each vertical shaft 38 is linked to a common drive device, so that the movement of each drum-shaped roller 35 toward and away from the pre-binding coil 3 is performed simultaneously and in the same direction.

Feeder 11 The inside of the case body 39 supported on the side of the bracket 9 is divided into left and right sides by a partition wall 40 .

A feed roller 42 and a presser roller 43 are placed facing each other from above and below with respect to a wire supply path 41 formed in one chamber.
and are placed.

A plurality of sets (five sets in the embodiment) of these rollers 42 and 43 are arranged in a straight line in the direction of the wire supply path 41, with one set facing each other.

Furthermore, in adjacent pairs, the phases are changed in a staggered manner.

That is, when the feed rollers 42 of one set are on the upper side, the feed rollers 42 of the adjacent set are on the upper side.

The feed roller 42 is fixed to one end of a rotating shaft 45 supported by the partition wall 40 via a bearing 44, and a passive gear 46 fixed to the other end of the rotating shaft 45 is meshed between adjacent sets. In addition to constant-velocity interlocking, one passive gear 46 is meshed with a drive gear 49 attached to an output shaft 48 of an air motor 47 that can be driven in forward and reverse directions.

The presser roller 43 is attached to a fixed shaft 51 attached to a movable table 50.
A compression coil spring 53 is interposed between the fixed base 52 attached to the case body 39 and the movable base 50.

Here, each compression coil has an equal spring force, and therefore a uniform clamping force is generated between each set of rollers 42 and 43.

The outer periphery of the feed roller 42 is formed into a flat clamping surface 42a, and the outer periphery of the press roller 43 is formed into a recessed clamping surface 43a.
is formed.

A wire guide 54 is arranged between each rough space.

Note that the clamping surfaces of both rollers 42 and 43 may be both flattened or both shaped into a four-figure shape depending on the wire diameter.

Next, the binding work will be explained.

Before the binding work, the following situation is established.

That is, the cart 8 is moved by operating the racket handle 17 in accordance with the size of the coil 3, and the binding head 6 is positioned directly above the portion of the coil 3 to be bound.

Further, the guide track 12 is moving upward, the positioning device 5 is moving away, and the elevating and rotating device 4 is descending.

In this state, the coils immediately after being bundled are carried out by the conveyors 1 and 2, and at the same time, the coils 3 before being bundled are carried in.

When this is carried in, the type of coil 3 (particularly the difference in outer diameter) is determined using a phototube, and based on this, the coil 3 is stopped approximately at the center of the binding machine.

In this state, the coil receiver is moved up and down by the operation of the rotation device 4.
4 and lift the coil 3 slightly from above the conveyors 1 and 2 to bring it to an intermediate position.

Next, the positioning device 5 is operated to align the coils 3 with respect to the binding center by clamping each of the advanced drum-shaped rollers 35, and at the same time to correct any collapse of the load that has occurred during conveyance.

This operation of the positioning device 5 is repeated multiple times to increase the positioning function.

Next, the coil receiver part 34 is rotated by 45 degrees by the rotating part of the lifting and rotating device 4.

This is done to prevent collision between the cross-shaped arms and the guide track 12, etc.

Now we move on to the binding cycle.

That is, the feeder 11 operates normally, and the wire 10 is drawn out and fed from the wire dispenser 18 side without becoming entangled.

At this time, in the feeder 11, the feeding is carried out at a plurality of locations by the pinching and conveying force of the feed roller 42 and the presser roller 43.
Furthermore, since one of the contact surfaces is the concave holding surface 43a, the conveyance can be carried out suitably without slippage.

The sent out wire 10 surrounds the coil 3 via the guide track 12, and its tip is held by the binding head 6.

Next, the feeder 11 rotates in the opposite direction, and the wire 10 is pulled back with the aforementioned clamping and conveying force.

As a result, the loop of the wire 10 becomes smaller and tightens as it comes into contact with the coil 3. At this time, the elevating and rotating device 4 is activated to raise the coil 3, thereby sufficiently pulling back the wire 10. .

After the feeder 11 stops pulling back, the binding head 6 is operated to clamp the wire 10 in the middle.

Next, the wire 10 is rotated while holding the tip and the middle, thereby cutting the middle and forming a twist.

Next, the coil 3 is lowered to an intermediate position by the downward movement of the lifting and rotating device 4, and then rotated by 90 degrees by the rotary movement to bring the next binding point to face the binding head 6.

This completes one round of binding, and the binding is performed at four locations in the same manner.

When this bundling is completed, the coil receiver portion 34 is rotated 45 degrees and lowered to the lowest position to transfer the bound coils 3 to the conveyors 1 and 2, thereby completing all operations.

If the wire bundle is fed and pulled back using a pair of feed rollers and press rollers, the wire wire located between the two rollers may become twisted or slip, making it impossible to expect the desired conveying force.

In contrast to this, according to the present invention, a plurality of sets of feed rollers and presser rollers are arranged in a straight line in the binding wire transport direction, and the feed rollers are arranged in a staggered manner with the binding wire as the center. It is possible to prevent the occurrence of bending of the binding wire due to the arrangement direction of the binding wire and bending of the binding wire due to the feeding force during feeding.
