Description

Description: TECHNICAL FIELD The present invention relates to a binding machine used for binding and fixing reinforcing bars and the like with a metal wire rod.

[Background technology]

BACKGROUND ART In reinforcing bar binding work in the construction work of reinforced concrete structures, or in log assembly work for work scaffolding in a construction workshop or the like, binding of rebars or logs is performed using a metal wire rod such as wire. Conventionally, all of this has been done manually by an operator. Therefore, the work efficiency is very low and inferior, and the whole work is often delayed due to the delay in the work that requires binding such as rebar assembly work. Further, most of the binding work uses the hands and the work is performed in an unnatural posture, so that the worker often feels pain. Particularly, in the work of binding the reinforcing bars, the amount of work is enormous, and the worker is more likely to feel pain.
Further, in recent years, because of the poor retention rate of young workers due to the poor working environment and the like, the elderly have become the majority of workers. For this reason, a number of problems have come to occur, such as a decrease in work efficiency and the occurrence of back pain due to an unnatural posture such as bending down.

Therefore, a binding machine that automatically binds was developed. The binding machine is disclosed in Japanese Examined Patent Publication No. 59-39027. This binding machine has a binding wire winding means having a guide forming pipe whose tip portion is curved in a semi-arc shape, a binding wire feeding means for feeding a binding wire such as wire to the winding means, and a feeding means for feeding the binding wire. An opening / closing claw for gripping the wound binding wire winding portion, a binding wire twisting means for rotating the opening / closing claw, and a binding wire disconnecting means for separating the binding wire winding portion are provided. As the feeding means, there is used one in which a binding wire is sandwiched between two rollers and one roller is rotated to feed the binding wire. This binding machine is designed to bind as follows. First, the feeding means pulls out the binding wire wound around the winding bobbin or the like and feeds it to the winding means. The binding wire sent to the winding means is formed into an arc shape and wound around a bound object such as a bar. After gripping this winding part with the opening and closing claw,
The winding part is twisted by rotating the open / close claw by the twisting means. Next, the winding part that binds the to-be-bound means is separated by the separating means. The separation may be performed before the winding part is gripped by the opening / closing claw.

However, this binding machine has the following problems. That is, the binding after forming may be performed depending on conditions such as curling, bending, and warping generated in the winding bobbin of the binding wire, the pressing force of the roller of the feeding means, the hole shape of the guide forming pipe, and the thickness and hardness of the binding wire. Variation in the radial direction of the winding part due to the springback of the wire (normally 0 to 4 mm in terms of the variation of the winding diameter), and variation in the width direction (such as coil spring 2.
5), usually 0-6 mm] occurs, and it is a problem that it is difficult to send the binding wire in a reliable shape every time. When the above-mentioned variation occurs, the whole wire of the winding part is securely gripped (generally, the gripping part of the winding part is 3 wires, and the entire winding part is cut into about 2.5 turns). It becomes difficult to do so, and there is a high possibility that the binding cannot be tightened. This is because if one line cannot be gripped, the binding cannot be tightened. When the winding part is separated before the winding part is gripped by the opening / closing claw, the winding part is likely to be separated at the time of separation, and thus it becomes more difficult to reliably grip the winding part. Further, when the binding wire is sent out, it is necessary to position the binding machine so that there is a gap between the tip end portion of the molding pipe curved in a semi-circular arc and the binding object so that the binding object does not hit the binding object. However, there is a problem in that it is extremely difficult for an operator to hold the binding machine by hand.

[Object of the Invention]

The present invention has been made in view of such circumstances, and an object thereof is to provide a binding machine that can perform binding reliably and easily.

[Disclosure of Invention]

Then, the guide member 10 and the holding means C are hung on the rods 3, 3 (see FIG. 11), and the binding machine is pulled toward the operator by about 30 mm, and a part of the winding portion 11a is pulled by the rods 3, 3. Deform it so that it closely contacts the outer peripheral surface of 3 (see Figs. 11 and 12). After this, switch 6 is turned ON in the same state.
Then, only the motor 19 is rotated and the twisting means F is rotated to twist the winding portion 11a, and the cylindrical body (clutch cylinder) 61 performs a sliding rotation operation to rotate the twisting means F. When it stops, switch 6 is turned off. Then, the handle 8 is released to release the grip of the claw member 46. Then, the chuck member 48 returns to the original fixed position, and the claw member 46 stands still at a predetermined position where the binding wire 10 to be wound next can be grasped. This completes the entire process of binding the rod members 3, 3. If a charger that can use a commercial power source is used, commercial electricity can be used for the binding machine through the charger by connecting the charger to an outlet even at a work site. Using a spare battery pack is also efficient and easy, and eliminates the need for conductor connections as with batteries.

The winding means A and the feeding means B are fixed at appropriate positions with respect to the surface of the reinforcing bar 85 on the traveling direction side of the pushcart 84, and the base portion of the handle 8 and the lower end portion of the pushbutton switch 6 are attached to the pushcart handle (handheld). The grips 86, 87 and the hollow wire wires 88, 89 are separately fixed. Open and close the handles 86 and 87 manually, and
The guide member of the winding means A is set to the binding portion of the reinforcing bar 85, and the binding work is performed in the same manner as described above.

In the binding machine according to the present invention, since the holding means C is provided, the diameter of the winding bundle of the binding wire is made constant by the guide of the holding means C, and the holding of the holding means prevents variation of the winding bundle. . Therefore, the wound bundle can be reliably gripped, and the bound objects can be reliably bound. Further, since there is the holding means, even if the holding means touches the body to be bound, a space is secured between the body to be bound and the outlet of the guide member so that the binding line is sent out without being disturbed by the body to be bound. Further, it is possible to obtain an effect that it is possible to more reliably bind the objects to be bound.

As long as it is provided with each means and mechanism as in the above-mentioned embodiment, a series of operations from winding a binding wire around a member to be bound such as a reinforcing bar to twisting and tightening the wound binding wire is performed. Since the work can be performed as a work, the efficiency can be improved and the operator's fatigue can be significantly reduced. As long as it has a twisting torque adjusting mechanism as in the above embodiment, even if the thickness of the binding wire is changed according to the thickness of the bound object, the strength can be adjusted according to the thickness. The twisting force can be adjusted easily. As in the above-described embodiment, when the substrate of the feeding means regulates the positions of the cutting means E, the winding means A and the gripping means D and guides the movement, the cutting means operates. The operation of accommodating the wound binding wire with respect to the material to be bound, the operation of the gripping means, etc. becomes stable. Like the hand type of the above embodiment, if an auxiliary handle is provided,
Since it can be operated with both hands, the handleability is improved. As long as it is provided with a handcart as in the above-mentioned embodiment, it does not require the work of bending over at the time of binding work on the floor plane, and is most suitable as a countermeasure for low back pain. Further, the hand type of the above-mentioned embodiment is easy to use in standing work and has good workability. In this way, it is possible to improve the efficiency of both the work on the floor and the surface, and it is highly adaptable.
