ABSTRACT OF THE DISCLOSURE This invention is directed to a wire-feeding device, in particular. for the binding machines which are employed in the trussing yards of i-ronworks.
The device in accordance with the invention essentially comprises a wire-feeding wheel which is rotatable within a stationary ring, said wheel bein provided at its periphery with an annular groove for accommodating the wire and said stationary ring being provided with a Wire inlet passage and awire-outlet passage, said passages being both tangent to said annular groove of the wheel and adapted if necessary to intersect without coming into contact, said wheel additionally comprising at least one clamp which is intended to grip the wire either for the purpose of drawing said wire from the inlet passage towards the outlet passage or in the opposite direction, means being provided on the one hand for driving the wheel in rotation either in one direction or in the other and on the other hand for controlling the gripping and releasing action of the clamp independently of the movement of rotation of the wheel.
Preferably, the means for cont-rolling the gripping and releasing action of the clamp comprise a plunger which is axially slidable in the axis of the wheel.
In one form of construction of the invention, the clamp comprises a stationary jaw mounted in a slot of the wheel in the line of extension of one side of the annular groove and a movable jaw in oppositely-facing relation thereto and located substantially in the line of extension of the other side of the annular groove, said movable jaw being carried by one end of a lever which is pivoted about a pin located parallel to the plane of the wheel and at right angles to a radius thereof, the other end of said lever being supported on the plunger which slides axially in the axis of the wheel so as to control the gripping or releasing action of the jaws.
Said sliding plunger can be disposed within the hub of the wheel and thrust by a coaxial compression spring against said other end of the lever so as to initiate the gripping action of the jaws, a jack being provided for the purpose of producing action in the opposite direction on said other end of the lever in opposition to said spring so as to initiate the releasing action of the jaws.
As an alternative form, said other end of the lever can be pivotally coupled to one end of said plunger, the other end of said plunger being coupled, preferably by means of a reduction-gearing system, to a double-acting control jack which initiates the gripping and releasing action of the jaws.
In all cases, the device in accordance with the invention makes it possible either to feed or to withdraw the wire according to the direction of rotation of the wheel, with the result that said device can usefully be associatedwith a binding machine of the type employed in the trussing yards of ironworks, whilst a distribution system of a type which is known per se can be employed for co-ordinating the movements of rotation of the wheel either in one direction or in the other and the clamping and releasing movements of the jaws with the movements of the binding machine components.
One form of construction and an alternative form of construction according to the invention are illustrated my way of example in the accompanying drawings, in which:
FIG. 1 is a simplified front view of the device;
FIG. 2 is a simplified sectional view taken along line IIII of FIG. 1;
FIG. 3 is a detailed sectional view taken along line III-III of FIG. 2; and
FIG. 4 is a sectional vew of an alternative form which is similar to FIG. 2.
In the form of construction which is illustrated in FIGS. 1 to 3, the device comprises a wheel 1 which is rigidly fixed to a hub 2, said hub being mounted on ball bearings 3 in a bearing shell 4 of a stationary frame 5. There is mounted on said stationary frame 5 a ring 6 which is coaxial with the wheel 1.
The wheel 1 is provided at its periphery with an annular groove 7 which is enclosed by the ring 6 and forms a circular guide duct for the wire 8.
A portion of the ring 6 is constituted by a member 6a which is pierced by a passage 9 for the introduction of the wire and a passage 10 for the delivery of the wire. These two passages are both tangent to the circular duct which is formed by the annular groove 7 and the ring 6 and intersect within the member 6a without coming into con-tact with each other, both passages being slightly diverted for this purpose if necessary.
There is mounted on the wheel 1 a clamp comprising a stationary jaw 11 carried by a yoke 12 which is fixed in a slot 13 of the wheel, and a movable jaw 14 carried by one end of a lever 15 which is pivoted in said yoke about a pin 16 which is located parallel to the plane of the wheel and at right angles to a radius thereof. The stationary jaw 11 is located in the line of extension of one side of the annular groove 7 of the wheel 1 and the movable jaw 14 which is in oppositely-facing relation thereto is located substantially in the line of extension of the other side of said annular groove.
The other end 15a of the lever 15 is applied against one end of a plunger 17 which is slidably mounted in the axis of the hub 2 of the wheel 1. A coaxial compression sprin 18 is applied respectively against an internal annular shoulder of the hub 2 and against an annular shoulder of the plunger 17, thereby pressing lsaid plunger against the end 15a of the lever 15 and consequently having a tendency to clamp the movable jaw 14 against the stationary jaw 11. The action of the spring 18 is limited by a stop ring 19 which is rigidly fixed to the other end of the plunger 17 and is abuttingly applied against the corresponding end of the hub 2.
A plunger 20 of a jack 21 is capable of applying force in the other direction against the end 15a of the lever 15 so as to separate the movable jaw 14 from the stationary jaw 11 while compressing the spring 18.
The wheel 1 can be driven in rotation either in one direction or the other from a motor 22, a driving pinion 24 being keyed on the shaft-end 23 of said motor and coupled by means of a chain 25 to a driven pinion 26 which is keyed on the hub 2 of the wheel 1.
The operation of the device can readily be understood. L
The wire 8 passes through the inlet passage 9 of the member 6a which forms part of the ring 6, passes around the wheel 1 within the circular duct formed by the annular groove 7 of said wheel and the stationary ring 6, and is finally discharged through the outlet passage 10 of said member 6a.
As long as the jack 21 remains inoperative, the lever is subjected to the pressure of the spring 18 by means of the sliding plunger 17 and the wire 8 is gripped between the jaws 11 and 14. If the wheel 1 is driven in rotation either in one direction or in the other by setting the motor 22 in motion in the appropriate direction, the wire 8 will be fed in a forward direction or, on the contrary, drawn backwards.
On the other hand, if the jack 21 comes into operation, the jack plunger 20 which exerts a thrust on the end 15a of the lever 15 while compressing the spring 18 initiates the opening of the movable jaw 14 with respect to the stationary jaw 11 and the wire is no longer clamped. The wheel 1 can then be caused to rotate either in forward motion or backward motion without displacing the wire 8.
In its application to a binding machine of the type employed in the trussing yards of ironworks, the initial operation of the motor 22 either in one direction or the other and the initial operation of the jack 21 are controlled in dependence on the movements of the binding machine components in order to supply said binding machine with a suitable length of wire, then to pull on the wire with a view to tightening the bond formed by the machine.
In the alternative form which is illustrated in FIG. 4, the same relative arrangement of the wheel 1 and of the stationary ring 6 is again shown. However, the hub 2 of the wheel 1 is driven from the motor 22 by a reduction- gear train 33, 34. In addition, the plunger 17 is pivotally coupled at one end to the extremity 15a of the lever 15 and at the other end to one extremity 27a of a lever 27, the other extremity of which is pivotally mounted at 28 with respect to the stationary frame 5. The cylinder of a double-acting control jack 29 is pivotally mounted at a fixed point 30 whilst the plunger stem 31 of said jack is pivotally mounted at 32 at an intermediate point of the lever 27. Said jack 29 accordingly serves to initiate the sliding motion of the plunger 17 either in one direction or the other and consequently the clamping or releasing action of the movable jaw 14 with respect to the stationary jaw 11. Otherwise, the operation of this alternative embodiment is identical with the form of construction which is illustrated in FIGS. 1 to 3.
The invention is in any case not limited to said form of construction or to said alternative form, in which detail modifications could be made without thereby departing either from the scope or the spirit of the invention.
