- the twisting assembly comprises a power unit driven by auxiliary power, such as electricity, pressurized medium or the like, the rotational movement of the same being transmitted to the binding hook for binding by means of a binding organ, such as a wire or the like, by a rotational movement around the longitudinal axis of the binding hook
- the twisting assembly comprises also a control device for controlling the operation of the binding machine, provided with at least a control organ, such as a current switch or the like for turning the power unit on and off.
- the binding machine is particularly intended for use in binding structural steel rods for reinforcement of concrete by a wire or the like.
- the binding device comprises a magazine supported by the body of the operator and a hand-held tool.
- the magazine contains e.g. a power supply battery and an electric motor, which are connected by a flexible shaft contained in a sleeve to the hand-held tool whose rotatable end part actually forms the working device that performs the binding.
- the magazine may also be used to contain a wire coil, in which case it is advantageous to arrange the wire to be conveyed by the said sleeve to the hand-held tool of the binding device.
- two different embodiments are presented of the hand-held tool of the binding device.
- the rotatable tool comprises an arrangement similar to pliers, the operation being based on the utilization of continuous wire uncoiled from the magazine.
- the tool comprises a hook which is used for twisting wire bindings provided with loops at the ends.
- the binding machine comprises an integrated body compris ⁇ ing- at least a power unit, such as a motor or the like, a fixing device, such as a socket or the like, preferably detachably attached to the power organ and provided with a binding hook, at least when in use, and a control device comprising, in addition to a current switch, an organ effecting on the basis of the reciprocal force between the binding hook and the body to the functioning of the binding machine, preferably with adjustable sensitivity, such as a moment switch or the like.
- the most important advantages of the binding machine according to the invention include both the construe- tion of the binding machine and the simplicity and reliability of its use, which are central requirements for developing a good installation technique.
- the compact structure of the binding machine according to the invention enables its use in a variety of condi ⁇ tions and environments. Also, it provides an ergonom- ically ideal construction, preventing stress injuries due to the recurrence of an operation. Further, it enables ideal binding so that a too loose or too tight binding is avoided.
- the person doing the reinforcing work does not need to have the skill required by the techniques presently used, because the machine goes off at a certain moment.
- using the binding machine according to the present invention is more inexpensive than the present solutions, because the binding work can be done clearly faster than with the present techniques.
- Fig. 1 shows an overall view of binding opera- tion using a binding machine according to the invention.
- Fig. 2 shows in principle a side view of the bindingmachine accordingto the invention.
- Fig. 3 shows a cross-sectional view in longitudi ⁇ nal direction of a detail of the socket and the binding hook fixed into it
- Fig. 3a shows a cross-sectional view in line A-A of Fig. 3
- Fig. 4 shows a cross-sectional view in longitudi ⁇ nal direction of a detail of the indexing means connected to the moment switch.
- the invention relates to a binding machine comprising a twisting assembly 1 and a binding hook 2.
- the binding machine is intended particularly for binding together structural steel rods for reinforcement of concrete.
- the twisting assembly 1 comprises of a power unit 3, the rotational movement of which being transmitted to the binding hook 2 for binding by means of a wire bond or the like, by a rotational movement w around the longitudinal axis of the binding hook 2.
- the twisting assembly 1 comprises also a control device 5 for controlling the operation of the binding machine, provided with at least a current switch 5a.
- the binding machine comprises an integrated body 6 which is composed of at least one power unit 3, such as a motor, a fixing device 4 attached to the power unit 3, such as a socket, in which the binding hook 2 is fixed either as a solid or a detachable piece, and of the control- device 5 provided with a moment switch 5b in addition to the current switch 5a.
- a power unit 3 such as a motor
- a fixing device 4 attached to the power unit 3, such as a socket
- the binding hook 2 is fixed either as a solid or a detachable piece
- the control- device 5 provided with a moment switch 5b in addition to the current switch 5a.
- the body 6 comprises a handle 6a designed to fit and to protect hand.
- the longitudinal direction K of the handle 6a is substan ⁇ tially at an angle differing from the longitudinal direction S of the binding hook.
- the current switch 5a of the control device 5 is placed in the handle 6a, most advantageous ⁇ ly to be operated by the index finger.
- the binding machine is also provided with a conventional on/off switch 5d maintaining the operation of the machine irrespective of the position of the current switch 5a.
- the binding machine comprises an adjustable moment switch 5b for obtaining the necessary tightness of the wire bond on basis of the reciprocal force between the binding hook 2 and the body 6.
- the power unit is most advantageously an electric motor 3 with adjustable speed and direction of rotation, wherein the twisting assembly 1 comprises a rechargeable bat ⁇ tery 8.
- the battery 8 is, because of its size, preferably placed e.g. to the belt, sleeve or pocket of the user, wherein the electric lead 8a connecting the battery 8 and the body 6 can be placed in connection with the working clothes so that it does not disturb the actual operation.
- the binding hook 2 is, as an advantageous embodiment, arranged detachably to the socket 4 by a fixing arrangement 7.
- the socket 4 comprises a barrel-like part 4a connected to the shaft of the motor 3 and a solid locking part 4b attached thereto with a thread ⁇ ed coupling.
- the fixing arrangement 7 comprises thus the first attachment organs 7a for preventing a reciprocal rotational movement of the binding hook 2 and the socket 4 and the second attachment organs 7b for preventing a reciprocal movement of the binding hook 2 and the socket 4 in the longitudinal direc- tion S.
- the first attach ⁇ ment organs 7a are arranged by an angular formation of the corresponding contact surfaces of the parts of the binding hook 2 and the barrel-like part 4a of the socket 4 coming into contact with each other, and the second attachment organs 7b are arranged by forming a lug in the binding hook 2, supported to the locking part 4b of the socket 4 in the axial direction.
- control device 5 comprises also a mechanically, electrically or by pressurized medium powered indexing means 5c which, in a situation of usage after binding and after detachment of the binding hook 2 from the bond, returns the binding hook 2 into an immobile standby position, wherein the tip 2a of the binding hook 2 is at a certain angular position ⁇ with respect to the co ⁇ ordinates of the rotational movement of the binding hook 2, as shown in Fig. 3a.
- This indexing means 5c is used to eliminate the problem that the binder should turn the device because of the random position of the binding hook 2 after the previous binding operation in order to find a correct position for performing the next binding operation with it.
- a mechanically powered indexing means 5c is shown for returning the position of the binding hook 2.
- the spring-loaded moment switch 5b in a manner that there is a pin 5bn on the circle of the moment disk 5bk, which is normally freely movable on the circle of the casing.
- the indexing means 5c can be most advantageously arranged to be adjustable so that e.g. by means of a separate angle adjustment organ, the standby position of the binding hook 2 can be adjusted according to the needs of the user or the place of use into two or more angular positions.
- the body 6 of the binding machine can also be used to operations of different kind, because the binding hook 2 is detach ⁇ able from the fixing device 4.
- a conventional socket formed of movable jaws is used as the fixing device 4, the body 6 can be used with suitable equip ⁇ ment e.g. for drilling, screwing in, unscrewing, or the like.
- An embodiment of this kind is, however, most advantageous in so-called everyman's use, because the weight or size of the body 6 may exceed the optimum for use of the machine in continuous binding work.
- the fixing device 4 which is according to the invention detachably connected to the power unit 3 and provided with the binding hook 2, can be replaced by a new one, in which case the whole machine does not need to be replaced.
- the binding machine according to the invention is used so that a wire, provided with loops at each end, is placed around the steels to be bound, whereafter the binding hook 2 of the binding machine is inserted through both loops.
- the motor 3 is started by pressing the current switch 5a, and the binding hook 2 fixed to the socket 4 connected thereto starts rota ⁇ ting w.
- the rotational speed of the electric motor 3 is adjusted to suit the length and strength of the wire, e.g. by a linear function of the current switch 5a, so that the highest rotational speed of the electric motor 3 is achieved by pressing it down.
- the moment switch 5b is used to tighten the wire into a suitable tightness. Consequently, it is possible to perform without previous occupational experience the operation which in manual binding requires skilled finger sensitivity to prevent breaking of the wire.
- the binding hook 2 is removed from the bond, whereafter the positioning organ 5c returns the binding hook 2 into the immobile standby position for the next binding operation.
- the battery 8 separate from the body 6 has the advantage of minimizing the weight of the body 6, which provides expedient use of the binding machine. Consequently, fixing the battery e.g. to a belt enables the use of a more effective and a slightly heavier battery. Also, this enables the use of a binding machine at reinforcement work sites where it is almost without exception impossible or very risky to use e.g. power current or pressurized air as a power source because of risks related to occupational safety or the like.
- the appearance of the binding machine may vary to a large degree, depending on the quality of the components and their technical properties, such as the supply voltage, the speed of rotation, and the like.
- it is possible to arrange the position of the handle e.g. by means of a locking joint arrangement or the like, in which case the body can be kept straight when it is not in use and be bended for use according to the needs of the user or the place of use.
- the binding machine can comprise e.g. a central control unit similar to a control panel.
