Therefore, even if the surface of the object to be bound is slightly uneven, the tip of the gripper can follow the surface, so that the strap can be reliably gripped regardless of the binding condition of the strap. The gripper sliding member 60 is fitted in the lower part of the first sliding member, and is along the screw axis direction, that is, the third
In the figure, it is slidable to the left (in the opposite direction to the moving direction of the first sliding member) and can be elastically retracted by a spring 61. In FIG. 3, the first sliding member is at the starting position at the left end, and the tip 19A of the gripper 19 is not yet engaged with the edge of the strap, so it is not receiving any horizontal stress, and therefore the gripper The sliding member 60 is also in the right end starting position.
and the spring is at its most extended. Next, a horizontal hole with a diameter larger than that of the first sliding member is bored in the center of the second sliding member, and a gear nut 16 is rotatably supported inside the hole through a pair of bearings. In addition, the gear nut 16 is screwed onto the screw shaft 12.

However, the gripper 20 is directly pivoted to the second sliding member 26 and is fixed. The above is an outline of the configuration of the strap gripping mechanism in the embodiment of the device of the present invention. The attached strap cutting mechanism is shown in FIGS. 4 and 5, which are perspective views of the first sliding member and the second sliding member, respectively. As shown in the figure, they are arranged below each of the first and second sliding members in parallel with the gripping mechanism. The strap cutting mechanism is basically the same as the strap gripping mechanism, except that it has a pair of wedge-shaped blades instead of a pair of grippers. (Of course, the upper blade may not be wedge-shaped.) In other words,
Wedge-shaped blades 50 and 51 are pivoted to the lower ends of the first and second sliding members in parallel with the grippers 19 and 20.
, unlike the gripper 20, these tools have a shape suitable for cutting the strap by engaging with each other.

It is pivotably mounted by a pin 52 (not shown). Further, the lower blade 50 is always pressed downward by a spring 70 (not shown), so the tip of the lower blade 50 is attached to the pin 5.
2 (not shown) as the center of rotation, it is pressed downward so as to be in constant contact with the coil surface. Therefore, even if the surface of the object to be bound is slightly uneven, the cutting edge can follow the surface, and the strap can be gripped reliably. Further, at the lower end of the second sliding member 26, parallel to the gripper 20, a wedge-shaped upper blade 51 has its tip directed toward the first sliding member, and a pin 53 (not shown) is provided.
It is pivotably mounted by.

当接するに至る。Furthermore, inside the cutting and gripping head 8, both the first and second sliding members are separated into left and right end positions, and when the cutting head 8 contacts the upper surface of the coil, compressed air is supplied to the air motor 56 and the air motor rotates. , the drive gear 14 rotates, and the gear nut 16 engaged with the drive gear 14 also rotates. The next operation can be divided into two cases. One is when the screw shaft 12 does not rotate, and the other is when the screw shaft 1
2 rotates. The first case is a case where the movement resistance of the first sliding member is greater than the movement resistance of the second sliding member. In the second case, the movement resistance of the second sliding member is
This is a case where the movement resistance is large compared to the movement resistance of the sliding member. 1st
In this case, the second sliding member moves more easily than the first sliding member. Therefore, the screw shaft 12 does not rotate, the first sliding member 25 remains stopped, and the second sliding member 26 moves in the direction of the strap 1 due to the rotation of the toothed nut inside it, and the gripper The tip end 20A of the strap 20 comes into contact with the end edge 1A of the strap 1.

５がストラップ１の方向に進み把持子１９がストラップ
１の端縁部１Ｂに当接するに至る。In the second case, since the first sliding member moves more easily than the second sliding member, the screw shaft rotates together with the geared nut, and this time, the second sliding member 26 remains stationary and the first sliding member 26 moves more easily than the second sliding member. Moving member 2
5 advances toward the strap 1, and the gripper 19 comes into contact with the end edge 1B of the strap 1.
第１の場合と第２の場合は同時にまたは交互に、或は一
方的に起り、結局結束ストラップ１の両側から第１摺動
部材２５と第２摺動部材２６とが互い接近する。The first case and the second case occur simultaneously, alternately, or unilaterally, and eventually the first sliding member 25 and the second sliding member 26 approach each other from both sides of the binding strap 1.
この時点においてエアモータ５６は空圧原動機の特徴で
あるストール効果及びスプリング６１のバランスにより
、ストラップ１を把持子で挟持する方向に加圧しつつ一
時停止状態にある。At this point, the air motor 56 is in a temporarily stopped state while applying pressure in the direction of holding the strap 1 between the grippers due to the stall effect characteristic of the pneumatic motor and the balance of the spring 61.
もちろん一時停止せず連続動作も可能である。また前記

可能なことはいう迄も．ない。In the process of transitioning from the state shown in FIG. 6 to the state shown in FIG. 7, the elastic retraction mechanism of the gripper 19 is activated. That is, once the gripper 19 has reached the edge of the strap, it no longer moves, but since the gripper sliding member 60 slides in the direction of the screw axis inside the first sliding member, the first sliding member continues to advance. Since the second sliding member can be approached, the strap 1 can be cut while being held. Regarding the details of the cutting operation, applications have already been filed for a strap cutting device that uses a pair of wedge-shaped blades to engage, and a further developed strap cutting method and device that cuts only the upper strap of a superimposed strap (Japanese Patent Application No. 1983). -18025\Special application 1986-1
9886). After the cutting is completed, a part of the strap is held and carried to a strap packet 6 by the swinging action of the swinging arm 5 (see FIG. 2), where it is discarded. When discarded, the first and second sliding members are separated and the spring 61 causes the gripper sliding member 60 to return to its starting position. At the same time, the first and second sliding members also return to their starting positions and wait for the next strap or coil. Note that the tacho generator 15 (or limit switch)
