No. 211,689 Ciaiins priority, application Great Britain, Italy 29, I963, 27,669/61 Qiaims. (Cl. filth-12) This invention is for improvements in or relating to machines for securing a wire or other tie around an article.

One particular application of the invention, which is mentioned only by way of example, is to a machine for putting and securing a wire or like tie around a coil (e.g. a coil of wire) or bundle so as to secure the convolutions of the coil or the items making up the bundle together. Another typical application of the invention is to a machine for securing a tie, strap or binder around a box, packing case or similar article.

Coils of material such as wire or rod usually have their convolutions bound together by means of wire ties so as to form a compact coil or bundle suitable for transport and convenient for handling. Heretofore each tie or hinder has generally consisted of at least two turns around the convolutions of the coil, the free ends of the tie or binder then being secured together by twisting one end around the other. This is hereinafter referred to as a single twist.

One object of the invention is to provide a machine which is capable of producing an eifective tie consisting of only one convolution of wire instead of two as above referred to. This results in a considerable economy in material particularly when it is borne in mind that a coil of wire or the like usually requires at least three to four ties spaced circumferentially around it. A further object of the invention is to provide a machine in which the ends of the wire ties are secured together by a double twist as distinct from the single twist adopted heretofore.

According to the present invention there is provided a machine for securing a tie around an article comprising means adapted to embrace the article and having a groove, guideway or the like to receive or carry a tie which, when in or on the groove or the like will also embrace the article, the groove, guideway or the like being capable of releasing the tie when it is drawn therefrom, and means for drawing the tie out of or oif the groove or the like and tightly around the article.

According to a further feature of the present invention there is provided a machine for securing a tie around an article comprising a member or members adapted to embrace the article and having a laterally open or openable groove, guideway or the like, means for feeding or projecting a wire or like tie along or around said groove, guideway or the like and means for applying a pull to said tie so as to draw it out of or off said groove, guideway or the like and tightly around the box or other article.

According to a still further feature of the resent invention there is provided a machine for securing a tie or hinder around an article comprising a pair of openable arms adapted to embrace the article, a guideway, groove or the like for a length of tie or binder material extending around said arms, said guideway, groove or the like being open, at least in part, at one side of the arms so that the wire can leave the arms laterally thereof, resilient or releasable means covering or partly covering said guideway, groove or the like to retain the tie material therein, or thereon, means for feeding the tie material from stock through or onto said guideway, groove or the like so that aisaasr Fatented Feio. 2, HESS it will circumscribe the article, means for pulling on the tie in the reverse direction, vise means for holding a free end of the tie after it has circumscribed the article, means for severing the circumscribing loop from the tie stock and means for twisting the ends of the loop together after it has been pulled out of or off the guideway, groove or the like and drawn tightly around the article by said reverse pulling on the tie.

It will be appreciated that an important feature of the invention, as just set forth, is the provision in or on the arms of a guideway, groove or the like for the tie wire or other tie material. This guirleway or the like causes the tie wire to form a loop which circumscribes the article to be tied after which the free end of the tie is held in a vise. The tie is then pulled in the reverse direction (i.e. back in the direction from which it was fed, so that it is forced laterally out of or off the groove, guideway or the like against the restraint of the resilient or other means holding it therein or thereon, and is drawn tightly around the coil of wire or other article to be tied. When this has been done the tie is severed from the coil or stock of tie wire or other tie material and the two free ends of the tie, held in a twisting device, are twisted so as to secure them firmly together.

In preferred embodiments of the invention the twisting device is constructed so that the two ends are secured together by a double twist. In other words, each of said ends is twisted around the other instead of merely one end being twisted around the other as in a single twist.

The construction of a machine according to the present invention may be such that the twisted ends project neatly radially inwards from the bound coil of wire and therefore do not interfere with rolling or other handling of the coil and are not so liable to tear clothing or the like. These twisted wire ends can, of course, be bent so as to lie snugly against the inside of the coil if desired.

In one preferred embodiment of the invention the groove or guideway for the wire extends somewhat spirally for a complete circumference and a half of the arms which, when they are closed, take roughly the form of an oval or circle.

One particular embodiment of the invention will now bedescribed, by way of example, asapplied to a machine for securing ties around a coil of wire. In the following description reference is made to the accompanying diagrammatic drawings wherein:

FIGURE 4 is a fragmentary perspective view illustrating in detail the wire tie gripper, twister and cutter mechanism,

FIGURE 5 shows the initial setting-up position of the wire tie feeding mechanism,

FIGURE 6 shows the position of the wire tie feeding mechanism preparatory to the drawing of the wire tie tightly about the convolutions of the coil,

FIGURE 7 is a view similar to FIGURE 6 but showing the wire tie drawn tightly around the convolutions of the coil,

FIGURE 8 shows the positions of the wire tie twisting and cutter mechanism when the wire tie feeding mechanism or parts are in the position shown in FIGURE 6, and

FIGURE 9 shows the positions of the wire tie twisting and cutter mechanism when the wire tie feeding mechanism is in the position shown in FIGURE 7.

The machine comprises two arcuate arms 10 and 11 hingedly supported at 12 and 13 and geared together by reduction gear wheels 14 and 15. The gear wheel 14 is driven by an electric motor 16 for opening and closing of the arms as hereinafter described. The gear wheel 14 is geared to the motor 16 by a worm shaft 17 and worm wheel 18 fixed on a sleeve 19 to which the gear wheel 14 is also secured. The sleeve 19 is rotatably supported on a shaft 20 and its forward end provides the pivot 12 for the arm 10.

The gearing 14 and 15 between the arms is such that the top arm 10 moves faster than the bottom arm 11.

Mounted on the free end of the arm 11 is a wire tie gripper, twister and cutter mechanism which is indicated generally by the reference numeral 21. This mechanism comprises a gripper anvil 22, a slidably supported gripper 23, adapted to hold an end of the wire tie against the anvil 22, a twister wheel 24 and a cutter 25.

The gripper 23 is provided at its outer end with a roller 26 adapted to be engaged by a cam 27 pivotally supported at 28 on the free end of the upper arm 10. A clamping chain 29 extends from an arm 30 on the cam 27, around an idler sprocket wheel 31 on the free end of the lower arm 11, and then over a driving sprocket 32 to a fixed anchorage 33. Sprocket 32 is driven by a motor 34. When the chain 29 is under tension the cam 27 will, through the roller 26, move the gripper 23 towards the anvil 22 so as to clamp the wire W. This chain is also adapted for clamping the convolutions of the wire coil closely together before and during binding.

The twister wheel 24 has a twisting slot 36 and is rotated from a drive shaft 37 through gear wheels 38 and 39, the gear wheel 39 meshing with external teeth 40 on the twisting wheel. The drive shaft 37 is driven from a motor 41 through gear wheels 42 and 43, a clutch 44, shaft 45,

' worm and wormwheel 46 and 47, and shaft 48. The

shaft 48 carries a bevel pinion 49 which meshes with a bevel pinion 50 on the shaft 37.

The cutter 25 is pivotally supported on the upper part of a shaft 51 which carries the gear wheel 39. Operation of the cutter at the appropriate times is effected by a cam 52 fixed on the upper end of the shaft 37. The cutter 25 operates in conjunction with a hardened cutter bush 53.

A groove or guideway extends somewhat spirally for approximately a complete circumference and a ,half around the arms 10 and 11. This groove has a portion 54 which starts at or adjacent the hinge 12 and extends around the upper arm 10 to the free end thereof. The groove is continued as indicated at 55 around the lower arm 11 and then around the upper arm 10 again as indicated at 56 to terminate at the free end of said arm 10.

Wire stock, from supply roll S, FIG. 7, for making the ties is fed around the groove 54, 55, 56 by pairs of feed rollers 57 and 58 geared together and driven by the electric motor 41 through a gear wheel 59, clutch 60, the shaft 20, and a gear Wheel 61 on said shaft. The feeding rollers are mounted on the upper arm 10 for movement therewith, the concentric drive by the shaft 20 through the hinge or pivot sleeve 12, 19 of the arm permitting this.

The 'pontions 55 and 56 of the groove are open at the side face of the arms. To retain the tie wire in these portions of the groove said face is provided with arcuate cover plates. 62 and 63. These cover plates are loosely fitted over studs 64 on the arms and are held in position by spiral springs 64a located on said studs, the arrangement being such that when required the plates can give to enable the tie Wire to leave the grooves 55, 56 laterally.

To facilitate the lateral movement of the binder wire from the grooves 55, 56 the groove 55 atleast in the region 55a is radiused or chamfered. This chamfer which is located just where the back pull is most effective, allows the tie or binder wire to leave the groove freely. Once the binder wire has started to leave the groove its continued withdrawal is quite automatic.

The machine above described operates as follows:

When setting up the machine t(see FIGURE the free end of the tie-wire W from the coil of stock is fed into the feed wheels 57, 58 and carried round the part 54 of the groove, its free end terminating in the region of the free end of the upper arm 10. The arms are then opened to receive the coil C of wire to be tied or bound, the coil moves into position and the arms 10, 11 close around its convolutions and may be latched in this closed position. This latching operation may be effected by the tensioning and untensioning of the chain 29.

The feed rollers 57, 58 then operate by an appropriate amount to feed the wire W through the grooves 55, 56 through the slot 36 of the twisting wheel and into the gripper 22, 23.

The motor 34 is then operated to draw in the chain 29 and clamp it tightly about the coil C as shown in FIG- URE 6. Tensioning of the chain 29 also operates the cam 27 to close the gripper 22, 23 onto the free end of the binding wire.

The direction of rotation of the feed wheels 57, 58 is then reversed (e.g. by reversing the motor 41) so that the binder wire is pulled laterally from the groove 55, 56 under considerable tension. Means may be provided for ad usting this tension. As a result the single wire bond or tie loop is drawn tightly around the already clamped convolutions of the coil as shown in FIGURE 7.

The wheel 24 of the twister device then rotates and gives a predetermined number of twists to thewire tie as shown in FIGURE 9. During the first twist the cutter 25 is operated to cut the tie from the tie stock so that twisting can continue without difiiculty. When twisting or knotting of the ends of the tie has been completed the gripper 22, 23 is opened by release of the chain 29.

It will be noted (see FIGURES 8 and 9) that the twisting wheel 24 turns through an angle of from the position shown in FIGURE 8, in which its slot 36 is in the Start position for receiving the tie wire, to the position shown in FIGURE 9 in which the wheel is in the position it occupies at the end of a binding operation. In the position shown in FIGURE 8 the position of the slot 36 in the twisting wheel is such that it prevents the binding wire leaving when tension is applied whereas as soon as the full cycle of operations has been completed and the twisting Wheel turns through 180 to the feed position, the disposition of the slot is such that the binding is allowed to leave the twisting wheel.

Usually several ties will be applied to each coil of wire. This may be effected by, for example, turning the coil through an appropriate angle Within the arms 10, 11 and repeating the binding operation at each position. Alternatively the coil may be passed along a conveyor to a series of binding mechanisms having arms 10, 11 disposed at different angles. so as to apply bindings at different positions circumferentially around the coil of wire.

The arms 10,11 may be caused to open automatically, to release a coil, by arranging that a conveyor or table carrying the coil will move it, when the binding operation has been completed, so as to engage .a pivoted arm or other device which sets in operation the mechanism for opening the arms. Alternatively the application of the last binding or tie could be used to give a signal to cause the arms automatically to open for removal of the article.

Generally all the mechanism and the operation thereof as above described will be caused to take place automatically in the desired sequence, e.g. through a timing mechanism or by arranging for one mechanism at an appropriate time to trigger-off the operation of the next. In some cases, however, each operation or some of the operations may be controlled manually, e.g. by the operation of press buttons.

A complete cycle of operations can be initiated by the operation of one push button or may be arranged to become part of a number of operations on, for example, a conveyor line.

The grooves for the wire W could be replaced by spaced pins, blocks or by tracks adapted initially to support the loop of tie wire and off which it can be drawn and secured around the article.

In applying the invention to a maehinefor securing a tie around a box or like article the arms need not necessarily be arranged to open. The arms may in this case be replaced by a loop, ring or the like into the opening of which the box or the like is introduced.
