Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a binding machine used for binding and securing reinforcing bars and the like using metal wires.

[Background technology]

BACKGROUND ART In the work of tying reinforcing bars in the construction of reinforced concrete structures, or the work of assembling logs for work scaffolding in construction workshops, etc., reinforcing bars or logs are bound using metal wires such as wire. Conventionally, all of this has been done manually by an operator. As a result, work efficiency was extremely low, and the overall construction work was often delayed due to delays in work that required bundling, such as reinforcing bar assembly work. Furthermore, most of the tying work involves using the hands and in an unnatural posture, which often causes the worker to feel pain. In particular, in the work of tying reinforcing bars, the amount of work involved is enormous, and workers often experience pain. Furthermore, in recent years, the retention rate of young workers has been low due to factors such as poor working environments, so highly motivated workers have come to make up the majority of workers. As a result, a number of problems are occurring, such as a decrease in work efficiency and lower back pain due to unnatural postures such as bending over.

Therefore, a binding machine that automatically performs binding was developed. The binding machine is disclosed in Japanese Patent Publication No. 59-39027. This tying machine includes a tying wire winding means having a guide molding vibrator whose tip portion is curved in a semicircular arc shape, a tying wire feeding means for feeding a tying wire such as wire into the winding means, and a tying wire feeding means for feeding a tying wire such as wire into the winding means; The device is provided with an opening/closing pawl that grips the winding part of the binding wire in a wound shape, a binding wire twisting means for rotating the opening/closing pawl, and a binding wire cutting means for separating the binding wire winding part. As a means of sending
A device in which the binding wire is sandwiched between two rollers and the binding wire is sent out by rotating one of the rollers is used.

This binding machine performs binding as follows. First, the feeding means pulls out the binding wire wound around the winding boppin or the like and feeds it into the winding means. The binding wire fed into the winding means is formed into an arc shape and is wound around an object to be bound, such as a bar. After the winding part is gripped by the opening/closing pawl, the opening/closing pawl is rotated by the twisting means to twist the winding part. Next, the wound portion of the bundled means is separated by a separating means.

The separation may be performed before the opening/closing claw grips the winding portion.

However, this binding machine had the following problems. In other words, the bundling after forming depends on conditions such as curls, bends, and warps that occur in the winding boppin of the bundling 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 bundling wire. Variation in the radial direction of the winding part due to springback of the wire (normally 0 to 4 cranes in terms of variation in the winding diameter) and variation in the width direction (like a coil spring, the beginning and end of a spiral winding) Approximately 2,
The problem is that it is difficult to send out the binding wire in a reliable manner every time. If the above-mentioned variations occur, make sure to grip all the wires of the winding part (normally, the gripping part of the winding part is 3 wires, and the whole winding part is about 2.5 turns, then cut 1 wire). (analyzed)
This makes it difficult to tighten the bundle, and there is a high possibility that it will not be possible to tighten the bundle. This is because if even one wire cannot be gripped, binding and tightening will not be possible. If the winding part is separated before the opening/closing pawl grips the winding part, the winding part is likely to come apart during separation, making it even more difficult to grip the winding part reliably. In addition, when sending out the binding wire, it is necessary to position the binding machine so that there is a gap between the tip of the semicircularly curved molded part and the object to prevent the binding wire from hitting the object. However, there are also problems, such as the fact that it requires great care for the operator to securely hold the binding machine by hand.

[Purpose of the invention]

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

0 is always energized to be in the backward state.

A holding means C is provided on the side of the guide member 10. The holding means C guides the binding wire 1) sent out from the guide member 10 so that it forms an arc of approximately the same shape, and holds the wound portion 10a in the bundled state (so that it does not shift) so that the gripping means This is to ensure that the winding portion 1)a can be held securely. Here, the holding means C is formed by forming a bent body having a U-shaped cross section into an arc shape with the opening facing inward. As shown in FIG. 6, the holding means C has a wide inlet at the upper end, and gradually narrows the width interval toward the outlet at the lower end, and the outlet dimension is 1/3 of the inlet dimension a. ~1/4. Binding wire 1) sent out from the guide member 10 and passed through the cutting means E
is regulated by a guide fitting 45 provided on the cutting means E, and the tip first enters the upper end entrance of the holding means C. Thereafter, it goes around the inside of the holding means C and exits from the lower end exit.

Then, the winding portion 1)a having a predetermined number of turns is held by the holding means C. In this way, at the time when the binding wire 1) is sent out, the bar material 3, which is the object to be bound, is located near the inner opening of the holding means C in a state of being in contact with or being in contact with the binding wire 1). I will have to wait for the turn. The distance between the top and bottom of the holding means C (the missing portion of the circular arc portion) will vary depending on the distance required for taking in and out the bars that are the objects to be bound, and also depending on the thickness of the bars (in this case, 2 pieces). It is set in consideration of the interval required for rotation of the claw member 46 of the twisting means F (rotation radius escape). In order to adapt the wound binding wire 1) to the bar material (bringing a part of the wound part 1 a into close contact with the bar material), hook the guide member 10 or the holding means C to the bar material 3, 1) As shown by arrow X in the figure, the operator performs an operation to pull the binding machine backward. As described above, since the guide member 10 can move forward relative to the binding machine body, the binding machine can be pulled rearward with the guide member 10 or the holding means C hooked.

301) Head pulling, winding part 1) Part of a is bar 3,
(See Figure 1 and Figure 12). After that, while keeping the switch 6 ON, only the motor 19 is rotated, and the twisting means F is rotated to twist the winding part 1)a, so that the cylindrical body (clutch tube) 61 slips. When the rotation operation is performed and the rotation of the torsion means F has stopped, the switch 6 is turned off. Then, the handle 8 is released to release the grip on the claw member 46. Then, the chuck member 48 returns to its original position, and the claw member 46 remains at a predetermined position where it can grip the binding wire 10 to be wound next. This completes the entire process of bundling the bar members 3.3. In addition, if you use a charger that can use commercial power, you will be able to connect the charger to an outlet at the work site.
Commercial electricity can be used for the binding machine via a charger. Using a spare battery pack is also efficient and convenient, eliminating the need for conductor connections as with batteries.

It should be noted that the holding means C is not limited to the one described in the above embodiment, but may be, for example, one in which a plurality of U-shaped pins 83 are arranged side by side as shown in FIG. It's okay. Here, the pin 83 is fixed to the arcuate tip portion of the guide member 10.

As shown in FIG. 19, the use of a handcart is very effective in reducing back pain. In this binding machine, a handcart 84 is equipped with the same means and devices as in the previous embodiment. On the side of the wheelbarrow 84 in the direction of movement, the reinforcing bar 8
The winding means A and the feeding means B are fixed at appropriate positions with respect to the five sides, and the main part of the handle 8 and the lower end of the push button switch 6 are connected to the wheelbarrow handle (hand grip) 86° 87 and the hollow wire wire 88. .89, each is fixed separately. While manually opening and closing the handles 86 and 87, the winding means A
Set the guide member and perform the binding operation in the same manner as described above.

Since the tying machine according to the present invention is provided with the holding means C, the diameter of the wound bundle of binding wire is made constant by the guidance thereof, and by holding this, the wound bundle of the wound bundle is prevented from becoming loose. . Therefore, the wound bundle can be gripped reliably, and the objects to be bound can be reliably bound. Furthermore, since there is a holding means, even if the holding means comes into contact with the objects to be bound, a space is secured between the objects to be bound and the exit of the guide member in which the binding wire can be sent out without being obstructed by the objects to be bound, Another effect is that objects to be bound can be bound more reliably.

In addition, if it is equipped with each means and mechanism as in the above embodiment, the entire process from winding the binding wire around the object to be bound, such as reinforcing bars, to twisting and tightening the wound binding wire can be completed. This can improve efficiency and significantly reduce worker fatigue. If it is equipped with a torsion torque adjustment mechanism like the above embodiment, even if the thickness of the binding wire is changed depending on the thickness of the objects to be bound, the strength can be adjusted freely depending on the thickness. The torsional force can be easily adjusted. As in the above embodiment, if the substrate of the feeding means regulates the position of the cutting means E1, the winding means A, and the gripping means, and also guides the movement, the operation 1 of the cutting means The operation of the gripping means 2 in which the wound binding wire is adapted to the material to be bound becomes stable. If an auxiliary handle is provided as in the hand type of the above embodiment, the handle can be operated with both hands, thereby improving the ease of handling. If it is equipped with a handcart as in the above-mentioned embodiment, it will not require bending at the waist during binding work on a normal plane, making it ideal for countermeasures against lower back pain. Further, the hand-held type of the above-mentioned embodiment is easy to use in standing work and has good workability. In this way, efficiency can be increased for both floor and elevation work, and it is highly adaptable.
