[Problems to be solved by the device]

 In the strapping machine, after forming a loop with the tape T, the binding object A is set on the table 1 so as to cross the loop. When the object to be bound A is relatively large, the size of the loop becomes large, the waist is broken due to the weight of the tape, the tape at the upper end of the loop hangs down, and the loop often collapses. . In that case, one hand must lift the hanging tape and the other hand must set the material to be bound A in the loop, which makes strapping work difficult and reduces work efficiency. Was there. The purpose of this invention is to solve such inconvenience.

[0004]

[Means for Solving the Problems]

 After rotating the feeding roller, the tape is fed from the tape passage groove provided on the table onto the table to form a loop, and the object to be bound is placed on the table so as to cross the loop. A banding machine in which a binding roller is rotated to pull back a rear end portion of the tape to wind the tape so that the tape is closely attached to an object to be bound, and a start end portion and an end portion of the tape are adhered to each other. In the above, there is provided a tape keeper that protrudes into the loop in synchronization with the formation of the loop and prevents the tape above the loop from hanging down.

【Example】

 As shown in FIGS. 1 to 3, the strapping machine has a pair of arms 87 and 88 projecting upward from both sides of a rectangular parallelepiped main body 86, and the projecting ends of these arms are connected by a connecting portion 89. A rectangular through hole 89 is formed by being surrounded by the main body 86, the arms 87, 88 and the connecting portion 89. In the main body 86, the delivery / bundling roller 32, the auxiliary roller 34, the movable holding tool 8, the receiving plate 2, the holding plate 21 and the like described in the conventional example are housed.

On the table 1 forming the upper surface of the main body 86, a passage groove 110 for sending and pulling back the tape T is formed extending between the arms 87 and 88 and extending left and right. A passage groove 110a is also formed in the connecting portion 89 so as to overlap the passage groove 110. An opening 120 is formed on the upper surface of the connecting portion 89 so as to communicate with the passage groove 110a so that a part of the tape T can be projected upward. A passage groove 110b is formed on the inner surface of the arm 88 so as to communicate with the table 1 and the passage grooves 110 and 110a of the connecting portion 89, and is also communicated with the through hole 89. A pair of guide plates 90 extend upward from the front edge and the rear edge of the passage groove 110 on the left end side of the table 1 and are respectively connected to the bottom surface of the connecting portion 89. A pair of guide plates 90 facing each other form a tape passage groove.

In this invention, the tape keeper 85 is extended in the left and right direction inside the connecting portion 89 in order to prevent the tape on the upper part of the loop formed along the tape passage groove from hanging down by its own weight and collapsing the loop. The tape that has started to hang down is temporarily held. In the tape keeper 85, a pair of support plates 97 and 107 are provided so as to project upwards so as to be slightly inside of both ends of an elongated rectangular plate-shaped base 91 fixed to the housing of the connecting portion 89. The rotary shafts 92a and 102a are rotatably attached to these support plates. A slit is formed in the axial direction on the opposing end surfaces of the rotary shafts 92a and 102a, and a pair of arms 86d and 86e of the keep bar 86 are fitted and fixed to the slit. The keep bar 86 is made of, for example, a thin aluminum plate.

The left end of the rotary shaft 92 a is fitted and fixed to the center of the swing block 92, slightly near the upper end. A guide pin 92c is fitted and fixed to the left end surface of the swing block 92 below the rotary shaft 92a. The protruding end of the guide pin 92c is engaged with an engaging piece 93a formed on the right end of the arm 93 (see FIG. 4). The arm 93 is made of an elongated rectangular plate, and a through hole formed substantially at the center of the arm 93 is rotatably engaged and supported by a rotary shaft projecting from the upper end surface of the spacer 94, and an engaging piece 93 a of the arm 93 is provided. The right end is bent and extended upward at a right angle, and an engaging groove that engages with the guide pin 92c is formed in the engaging piece 93a. The spacer 94 is vertically planted in the base 91.

A left end portion of the base 91 is extended rearward to have a wide width, a left end edge of the extension portion is bent and extended upward at a right angle, and a solenoid 95 is attached to a left end surface of the bent extension portion. A plunger 98 is held by the solenoid 95 so as to be able to move forward and backward, and a projecting end of the plunger 98 is connected to a left end of the arm 93. One end of the coil spring 96 is attached to the projecting end of the arm 86d of the tape bar, and the other end is fixed to the front side edge of the base 91.

At a time point shortly before the loop reaches its maximum when the feeding / bundling roller 32 feeds the tape T, the keep bar 86 of the tape keeper is projected into the passage groove 110a of the tape T so that the tape above the loop is released. I try to catch the droop on the way. Therefore, the solenoid 95 is turned off and the plunger 98 is released. In FIG. 4A, the keep bar 86 is biased by the coil spring 96, and the guide pin 92c fixed to the keep bar 86 via the rotating shaft 92a and the swing block 92 passes the tape through the engaging piece 93a side of the arm 93. It is displaced to the groove 110a side. Therefore, the arm 93 is slightly rotated counterclockwise around the rotation shaft 94a (FIG. 1A) of the spacer 94 when viewed from above. Along with this, the plunger 98 connected to the left end of the arm 93 is pulled out slightly forward. Since solenoid 95 is off, it does not interfere with this displacement of plunger 98.

The loop has a maximum diameter on the left end side at which the tape is first fed out, and becomes the maximum on the right end side with a slight delay. Therefore, it is desirable that the keep bar 86 is first projected to the left end side of the passage groove 110a and is gradually delayed toward the right end side. Therefore, the stroke of the arm 86d of the keep bar (the length from the keep bar 86 to the position where the rotary shaft 92a is locked) is made shorter than the stroke of the arm 86e (the length from the keep bar 92 to the position where the rotary shaft 102a is locked). There is.

As shown in FIG. 5B, the tip of the tape T is clamped between the receiving plate 2 and the clamping plate 21, and the tape T is further fed out by the feeding / bundling roller 32 so that the loop becomes maximum. Just before that, the tape keeper 85 is projected into the passage groove 110a. Even if the tape on the upper end of the loop begins to hang down, it is stopped by the tape keeper 85 and does not hang down below it. Therefore, the object to be bound A can be placed on the table 1 so as to easily cross the loop.

In order to bind the tape T to the object to be bound A, in the same manner as shown in FIG. 5C, the feeding / bundling roller 32 is reversed, and the tape is pulled in, the loop is shortened, and the tape is bound to the object to be bound A. In close contact with. Since it is necessary to return the tape keeper 85 to its original position outside the passage groove 110a in synchronism with the reverse rotation of the delivery / bundling roller 32, the solenoid 95 is turned on and the plunger 98 is set in the solenoid 95 as shown in FIG. Is sucked into. As a result, the arm 93 is rotated in the clockwise direction around the rotation shaft 94a and is made substantially parallel to the base 91. As a result, the swing block 92 (the rotation shaft 92a is rotatably supported by the support plate 97) engaged with the engagement piece 93a at the right end of the arm 93 via the guide pin 92c is shown in FIG. 4B. Thus, the rotary shaft 92a is rotated counterclockwise around the axis of the rotary shaft 92a. As a result, the tape keeper 85 in which the arm 86d is locked in the slit of the rotary shaft 92a is rotated clockwise together with the rotary shaft 92a and returned to the outside of the passage groove 110a.
