Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method in which a string receiving section receives a string from a string supply section in order to wrap a long string such as hemp string used for binding objects to be bound. This invention relates to a string twisting device that can be received.

In recent years, in order to efficiently carry out packaging and other packing operations that require stringing, various attempts have been made to automate the process of tying the objects by stringing them around the outer periphery of the objects, such as cardboard packaging boxes. .

According to the present invention, such a lanyard is useful in cases where work is to be carried out automatically, or in cases where a string wound around a reel is to be pulled out. A string supply section capable of holding the tip of the string and a string receiving section capable of receiving the tip of the string are arranged facing each other on the main body so as to abut and separate from each other, and the string receiving section a movable pawl pivoted on a fixed pawl so that the side facing the cord supply section opens and closes; a first position that opens to release the cord; and a second position that closes to latch and hold the cord; a slidable actuating rod for displacing the movable pawls to respective positions, and the movement of the movable pawls to the first position is performed by pressing and moving the actuating rod by a pressing means; Movement to the second position is carried out by bringing the actuating rod into contact with the supplying section and pushing it against the pressing force of the pressing means, and when the receiving section comes into contact with the supplying section, the receiving section The device is characterized in that the device is adapted to grab the string held in the supply section.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 3, the string receiving part 1 includes a fixed claw 3 provided at the tip of the arm shaft body 2, an actuating rod 4 that can freely reciprocate, and a screw 5 for attaching the fixed claw 3. It is composed of a movable claw 6 rotatably supported as a fulcrum.

The fixing claw 3 has a long groove 7a carved on the side of the fixing claw 3, and a cover plate 1 fixed to the fixing claw 3 with screws 8 and 9.
A tunnel hole 7 for sliding is formed on the 0 side by a long groove 7b carved corresponding to the long groove 7a,
A reciprocating actuating rod 4 is provided within the tunnel hole T.

Near the center of the actuating rod 4, a slide pin 11 is inserted and fitted into a through hole from a direction substantially perpendicular to the length direction of the actuating rod 4.

In the above case, the slide pin 11 and the actuating rod 4 are formed separately, but the invention is not limited to this. For example, a projection having the same shape as the slide pin 11 may be formed near the center of the actuating rod 4. It is also possible to provide the same function as the slide pin 11 by protruding it.

A substantially W-shaped leaf spring 12 that comes into contact with the upper end of the slide pin 11 is attached to the top of the operating rod 4 in the figure, and connects the cover plate 10 and the fixing claw 3.
It is housed in a box-shaped space formed by.

The movable claw 6, which is rotatably supported on the fixed claw 3 by a mounting screw 5, has a movable claw 6 at its leading edge, that is, at the left end in the figure.
A protruding latching part 14 for latching the string by the holding recess 13 of the fixing claw 3, and abutting the lower end of the slide pin 11 in the upward direction in the figure behind the latching part 14; An inclined surface 15 formed in a gently curved shape is formed.

Next, the operation of the present invention will be described with reference to FIGS. 1 to 6.

First, a case will be described in which the movable claw 6 is closed, that is, displaced to the second position in order for the string receiving portion 1 to pick up the string.

A string supply section 16 that can freely reciprocate and holds a string a to be supplied to the string receiving section 1 by the driving action of a drive source (not shown) (this string supply section 16 is not limited to the illustrated example) is in contact with the tip 4a of the actuating rod 4 (in the illustrated example, the pressing surface 4b is in contact with the tip 4a), and the rod 4
When pressed, the actuating rod 4 slides inside the tunnel 7 and moves to the right in the figure.

Along with this movement, the slide pin 11 moves to the right in the figure against the spring plate 12, that is, along the inclined surface 15 of the movable claw 6.

The movable claw 6 is gradually rotated clockwise about the mounting screw 5 by the pressing action of the slide pin 11.

Due to this rotation, the latching portion 14 of the movable claw 6 latches and holds the string a through a clamping action with the holding recess 13 of the fixed claw 3.

After this, if the string receiving part 1 is moved to the desired position, the string a is held by the string receiving part 1, and the string a is held by the string receiving part 1.
accompanies and moves.

Therefore, the objects to be bound are placed between the string supply section 16 and the string receiving section 1, the string a of the string supply section 16 is grasped by the string receiving section 1, and then they are separated from each other, and the string receiving section 1 runs around the outer periphery of the object to be bound, it becomes possible to wrap the string a around the outer periphery of the object to be bound.

Then, as described above, the movable pawl 6 is opened relative to the fixed pawl 3 in order to release the string from the second position in which the movable pawl 6 is closed relative to the fixed pawl 3 for gripping the string, i.e. To describe the case where the actuating rod 4 is displaced to the first position, the pull-out pin 17 formed upright on the actuating rod 4 is moved while being pressed to the left in the figure, or the tunnel 7 on which the actuating rod 4 slides is further moved. The actuating rod 4 is moved by a method such as extending to the right in the figure, and providing a pressing means for pressing the right end of the actuating rod 4 from the right direction in the figure in the tunnel portion, and moving the actuating rod 4 by pressing it. The slide pin 11 fixed to the actuating rod 4 also resists the spring plate 12 and moves to the left in the figure along the inclined surface 15.

When the slide pin 11 moves to the left in the figure, the slide pin 11 presses the movable claw 6 counterclockwise using the installation screw 5 as a fulcrum, as shown in FIG. Thus, the string a held between the holding recess 13 of the fixed claw 3 and the latching portion 14 of the movable claw 6 is released.

In this way, the actuating rod 4 is moved to the left in the figure, and the movable claw 6 is rotated by the slide pin 11 that moves along with it. It is designed to be canceled.

As described above, according to the present invention, when necessary, the string held in the string supply section can be moved by simply bringing the string supply section and the string receiving section close to each other and pushing the operating rod into contact with the supply section. can be grasped.

Moreover, if the pushing state of the operating rod is released, the receiving section can automatically release the holding state of the string.

Further, since the string gripping operation of the receiving section is performed by pressing the passive frame against the supplying section and bringing the receiving section into contact with the supplying section, it is possible to securely clamp the string, and the structure Since it is simple, it can be expected to greatly reduce costs, which is extremely useful in practice.
