Abstract

PURPOSE:To ensure the disengagement of the end of a band from its button by holding the band end between band holding members, releasing the band end after tying a knot and holding a new band end therebetween before cutting the former band by a cutter. CONSTITUTION:An object placed for typing on a table is bound with a band by the rotational or vertical movement of a tying arm with the end of the band held between band holding members 11 and 12. The beginning and end parts of the band wound around the object are then brought close to a beak 4 by a band inserting rod to thereby tie a knot. The band holding member 12 is thereafter moved downward by the action of a driving device 14 to release a band end S1 and, immediately thereafter, the band holding member 12 is moved back by the driving device 14 to thereby hold a part S2 of a new band between itself and the band holding member 11, followed by the cutting of the band S by a cutter 5.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a binding method and device for binding articles with rubber strings.

(Prior Art) Conventionally, as an example of a binding device, for example, the Japanese Patent Publication No. 58-396
The one shown in Publication No. 93 is known.

FIGS. 9 and 10 show such conventional examples, in which (1) is a binding arm, which is a cam (1) attached to the main shaft of the binding device.
8) and links (9), etc., to swing up and down.

A knot forming mechanism operated in conjunction with the tying arm (1) is installed under the table (10) on which the objects to be tied are placed, and as shown in FIG. 2) and 5. A string insertion rod (3) that moves the beginning and end of the string to the beak, a beak (4), and a cutter (
5), etc., and is bound by the following operations.

That is, in a binding device with an arm that moves up and down, the end of the string is pressed by the string button (2), and from there the tip (la) of the arm (1) is pressed.
), put the object to be bound on the table (10) so as to pull out the string, and then swing the arm (1) so that the end of the arm (1a) It descends, wraps the string around the object to be tied, and connects the beginning and end of the string around the object to the beak (4) with the string insertion rod (3).
) and form a knot by the operation of the beak,
The removed paper is attracted to the beak (4), so the end of the string is pushed by the string button (2) and moved slightly in the direction of removal, and the paper pushing part (6) moves forward together with the cutter (5), and that part ( At step 6), remove the end of the string from the string button (2) and use the cutter (
5), the part of the string at the end of the winding is cut, and the new end of the string created at this time is held between the string button (2) and attached to the arm (1).
) swings upward to complete one binding cycle. In addition,
In the arm rotation type binding device, when the object to be bound is placed on the table (10), the binding arm rotates to wrap the string around it, form a knot in the same way, and then pull out the end of the string and tie the end of the string. Cut the string and end the tying cycle.

(Problem to be solved by the invention) The string used for binding is not rubber but an ordinary string that does not stretch.
Or, if the elastic cord has very little stretch,
The end of the string that was pressed by the string button can be pulled out by the paper pushing part (6) and can be tied without any problems, but if the rubber string is made of elastic rubber, it will stretch by that amount even if it is pressed by the paper pushing part (6). They will not be able to escape on their own, and will be unable to unite. Also, the cutter (5) may come off from that part (6).
) and is cut there, it will not come off from the string button (2), and therefore the previous string end will not fall off but will accumulate around the string button (2), and as a result, it will hold down the new string end. There was a problem that it became impossible to bind, and it became impossible to bind.

An object of the present invention is to solve the above-mentioned problems, and therefore, to provide a binding method and device that can suitably perform binding using rubber strings.

(Means for Solving the Problems) The tying method according to the present invention is characterized by holding the end of the string between a pair of members in place of the conventional string button, and holding the end of the string between them before cutting it with a cutter after forming the knot. This involves releasing the previously held string end and pinching the part that will become the new string end, thereby ensuring that the string end can be pulled out from the string button.

In addition to the string button, the binding device according to the present invention includes a pair of paper pressing members, one of which is fixed and the other movable, and a drive device that operates the movable paper pressing member, and the end of the string is connected between the pair of paper pressing members. After the knot is formed, before cutting the string with a cutter, the string end is released and the part that will become the new string end is placed between the paper presser members. It is designed to be held in place.

(Function) Immediately after the knot is formed, the end of the string that had been held between the paper presser members is released before being cut by the cutter, so that the end of the string remains on the string button as in the past. The end of the string is always released and the new end of the string is reliably clamped without being cut by the cutter.

(Example) Next, an example of the present invention will be described with reference to the drawings. 1 to 4 show one form of the binding device according to the present invention, and although only the main parts are shown in the figures and the binding arms are omitted, it is possible to attach the objects to be bound in the same way as in the conventional case. A rotating, swinging or other type of tie arm is provided for wrapping the string.

The present invention is characterized by holding and releasing the end of the string, and as shown in FIG. 1, this knot forming mechanism includes a string button (2) and a string insertion lever (3).

A beak (4), a cutter (5), etc. are provided, and in the first embodiment, a pair of paper press members (11) and (12) are installed near the string button (2) to clamp the end of the string. Ru. Note that the string button (2) is used as a guide for the string. One paper pressing member (11) is fixed.

The other paper holding member (12) is movable, and the movable member (12) is connected to a suitable connecting member (12) such as a lever or a link.
13) may be operated by the drive device (14) by other devices such as an electric motor.

In the binding method using rubber strings of the present invention, preferably, the ends of the strings are held between a pair of paper press members (11) and (12).

Wrap the string around the object placed on the table (10) by rotating the tying arm or moving the tying arm up and down, and insert the string insertion rod ( 3), the beak (4) is brought closer to the beak (4), and a knot is tied by the beak. Until the knot is formed, a pair of paper pressing members (ii) and (1) are used in place of the conventional string button (2).
The present invention is the same as the conventional method except that the end of the string is held in step 2), but is different from the conventional method until the string is cut by the cutter (5) after the knot is formed.

That is, this binding method is characterized by releasing the string end after the knot is formed and before cutting the string with a cutter, and then pinching the part of the string at the end of the winding that will become the new string end. Therefore, after the part of the string that will become the new end of the string is clamped, the string is cut by the cutter (5). In the first form, after forming a knot, a cutter (
5) before the cutting is carried out, the drive device 1t (14)
As a result of the operation of
) is released, and immediately after that, the paper presser member (12) is moved forward again by the drive device (14) to create a new string end between the paper presser member (11) and the paper presser member (11) as shown in FIG. The part (
S2) is held between the strings (S2) and then the string (S) is cut by the cutter (5).
cutting is performed.

In the above embodiment, the end of the string is held between a pair of members (11) and (12) provided near the string button (2), but the movable member that abuts the fixed member (11) is the second member. As shown in FIGS. 5 and 6, it may be provided integrally with the string button (2), that is, it may be constructed as a part (15) of the string button (2). In this case, the string button (2) is rotatably supported, and is connected by a drive device (14) to a suitable transmission member 1, such as a rack (16) and a pinio, y (17), etc. as shown. The string button (2) is rotated by the button.

As shown in Fig. 5, the string is wound around the object to be tied and the knot is tied while the string end (S,) is held between the member (11) and the part (15) of the string button (2). carry out the formation,
Slightly rotate the string button (2) to attach the part (15) to the member (1).
1) to release the string end, immediately rotate in the opposite direction to sandwich the part that will become the new string end between the part (15) and the member (11), and immediately after that, cutter (5) ) to cut the string and complete one binding cycle.

Further, as a further form of this binding device, as shown in FIGS. 7 and 8, the corresponding portions of the pair of paper press members (11) and (12) that sandwich the ends of the string are attached to the string button (2). )
It may be composed of an end surface (20) on the string button side of the bearing part (19) of the shaft (18) and an end surface (21) on the inside of the string button (2) facing the end surface, and in this case, the string button (2) is installed movably in its axial direction and is configured to be reciprocated in the axial direction by a drive device (14).

In this form, when in operation, as shown in Fig. 7, the opposing end surfaces (20) and (21) abut each other, and the end of the string is held between them, and in this state, the string is hung on the object to be tied and the knot is tied. After the knot is formed, and before the cord is cut by the cutter, the driver (14) moves the cord button (2) to release the cord end and then brings the end faces (20) and (21) into contact again. The part of the string that will become the new end of the string is then held.

(Effects of the Invention) As described above, according to the present invention, the string end is released after the knot is formed and before the string is cut by the cutter, and the string end is removed because the part that will become the new string end is held. done perfectly,
