DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic binding machine.

[0002]

2. Description of the Related Art Heretofore, the following types of automatic binding machines have been known. That is, a cord winding arm that is configured to rotate around a binding object mounting table having a string passage and has a string insertion hole, an arm operating motor that operates the string winding arm, and an arm operating motor Is known which has a string end holding device, a string tying device, and a tying / cutting machine having a cutter which are operated by an operating mechanism such as a cam which is operated by a cam (see Japanese Patent Publication No. 57-13451). .

[0003]

Disadvantages of the prior art The conventional automatic binding machine has the following disadvantages. That is, since the tying / cutting machine is operated by an operating mechanism such as a cam operated by an arm operating motor, it is possible to wind the object to be tied only the number of times set in the automatic tying machine. There was a disadvantage that the number of windings could not be easily changed. More specifically, for example, in an automatic tying machine having two windings, the tying and cutting machine starts the arm operation from a predetermined time before the lace winding arm makes two rotations (for example, immediately after one rotation is completed). Since it was set so as to be operated by an operation mechanism such as a cam operated by a motor for use, it was not possible to perform winding other than twice.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a first embodiment of the present invention; In this specification, before / after /
Left and right refer to the directions shown in FIG.

A binding object mounting table 5 having a long cord passage 6 extending in the left-right direction is provided above the machine frame 2 of the automatic binding machine 1. The binding object placing table 5 is described in detail below so as to form a string passage 6 between the front table 5A fixed to the machine frame 2 and being long in the left-right direction and the front table 5A. And a rear table 5B provided on the machine casing 2 by means.

The rear table 5B is provided on the machine casing 2 as follows. That is, a vertical wall 9 is provided in the rear part of the machine casing 2 so as to protrude upward, and a bearing 10 is provided at the center of the upper part of the vertical wall 9 in the left-right direction so that the axis is directed in the front-rear direction. The rotating shaft 12 is rotatably fitted, and a hanging plate 13 is rotatably provided at the front end of the rotating shaft 12 via a bearing. The lower surface of the hanging plate 13 has the upper surface and the upper surface of the front table 5A. The rear table 5B is attached so as to be united. With such a configuration, even if the rotating shaft 12 rotates, the rear table 5B does not rotate with the rotating shaft 12. Further, an arm passage gap 14 is formed between the left and right portions of the rear table 5B and the machine casing 2 and between the vertical wall 9 and the hanging plate 13 to allow a cord winding arm 16 to be described later to pass.

An L-shaped string winding arm 16 is fixed to the rotating shaft 12. A string guide roller 17 is rotatably provided at a required portion of the string winding arm 16. A string insertion ring 18 having an insertion hole is provided. In order that the string winding arm 16 can rotate 360 degrees together with the rotating shaft 12, no member is projected in the movement locus of the string winding arm 16. The string winding arm 16 is rotated by an arm operating motor 19 (see FIG. 4). The rotating shaft 12 has a string passage 1
5 are formed.

Below the right end of the front table 5A,
String end holding device 22, string tying device 23 and cutter (not shown)
Is provided.
As is well known, the knotting / cutting machine 21 includes a rotating shaft 26.
Actuating mechanism (not shown) such as a cam provided on (see FIG. 4)
The predetermined operation is made to be performed.
That is, while the rotating shaft 26 makes one rotation, for example, the components (the string end pinching tool 22, the string tying tool 23, etc.) of the string knotting / cutting machine 21 are moved by an operating mechanism (not shown) such as a cam. 5
No. 7-59130, Japanese Utility Model Publication No. 4-41047,
A known operation is disclosed in Japanese Patent Publication No. 57-13451 or the like. The rotating shaft 26 is adapted to be rotated by a tying / cutting machine operating motor 27 (see FIG. 4).

The string S unwound from a winding tube (not shown) placed on the floor or the like passes through a string path 15, a string guide roller 17 and a string insertion ring 18 to a string end holding device 22 as is well known. It is made to be pinched.

Next, a control system according to an embodiment will be described with reference to FIG. A detection piece 31 protruding in the radial direction is provided on the rotating shaft 12.
Detector 32, such as a proximity switch, which is detected every one rotation of rotation 2, is fixed to machine frame 2.
The counter 34 is connected by a signal line. The first counter 34 receives one rotation signal of the string winding arm 16, and transmits a rotation signal to the crossing memory 35 each time the cord winding arm 16 is rotated. A stop signal is issued to the motor 19 for use.

When it is not stored in the middle of the ten-character hanging storage 35, a rotation signal is issued to the ten-character hanging setting device 37 when it is not stored. A rotation signal is issued to a third counter 41 described later.

The switch (not shown) of the cross-hook setting device 37 is turned on when it is crossed by ten characters, and remains off when it is not. A second counter 39 which operates when the cross-piece setting device 37 is ON and a third counter 41 which operates when the cross-setting device 37 is OFF are connected to the cross setting device 37 by signal lines.

The second counter 39 issues a stop signal to the arm operating motor 19 when the count number of revolutions reaches a set value, and outputs a signal for storing in the middle of the ten-letter storage 35 that the half-letter is in the middle of the ten-letter. It is issued to the memory 35 on the way.

The third counter 41 includes an AND circuit 4
6, and an AND circuit unit 46 is connected to a detector 45, which is composed of a proximity switch or the like and is fixed to the machine frame 2, and is fixed to the rotating shaft 12 so as to protrude in the radial direction. The detected piece 44 is detected for each rotation of the rotating shaft 12. The detected piece 44
Is configured to be detected by the detector 45 after the detected piece 31 is detected by the detector 32 with the rotation of the rotating shaft 12. And the third counter 4
1 is such that an operation signal is issued to the AND circuit unit 46 when the count rotation speed reaches a set value (may be zero). Thereafter, when a signal from the detector 45 is transmitted to the AND circuit 46, the AND circuit 4
Numeral 6 is adapted to issue an operation signal to a tying / cutting machine operating motor 27. It should be noted that the tying / cutting machine operating motor 27 is automatically stopped when the tying / cutting machine 21 completes a predetermined operation after the operation.

As shown in FIG. 5, in the middle of the cross, the object to be bound W is rotated 90 clockwise in a clockwise direction as viewed from a plane. Due to this horizontal rotation, the string S on the string end holding device 22 side and the string insertion ring 1 are located at the bottom center of the object W to be bound.
The strings S on the 8 side are engaged with each other, and those strings S and
And the string S wound around it cross when viewed from above.

[0018]

Next, the operation of the embodiment will be described. When the ten characters are not hung, the ten character hanger setting device 37 is in the OFF state, and the ten character hung storage unit 35 does not store that the ten characters are being hung. In this state, after the material W to be tied is placed at the set position of the material tying table 5, when the main switch (not shown) is turned on, the cord winding arm 16 rotates clockwise in FIG. The string S is wound around the binding object W. When the number of revolutions of the third counter 41 reaches a set value (a value smaller by one than the actual number of windings) and the detector 45 detects the detection target piece 44, the AND circuit unit 46 ties the string. An operation signal is issued to the cutting machine operation motor 27,
After the lacing / cutting machine 21 performs a predetermined operation, it stops.
In this state (in a state where the string S is cut), the string S on the side of the string winding arm 16 is automatically held by the string end holding tool 22. Thereafter, when the number of revolutions of the first counter 34 reaches a set value (a value equal to the actual number of windings), a stop signal is issued to the arm operating motor 19, and the string winding arm 16 is connected to a stopper (not shown) or the like. It stops at a predetermined position (a position where the string insertion ring 18 is slightly below and to the left of the binding object placing table 5) with help. In the case of crossing, the crossing setting device 37
Is turned on. In this state, it is not stored in the storage unit 35 in the middle of the ten characters in the middle of the ten characters. In this state, the object W to be tied is placed at the set position of the object tying table 5 and a main switch (not shown)
Is inserted, the string winding arm 16 rotates and the string S is wound around the object W to be bound. And the second counter 3
When the count number of rotations 9 reaches a set value (a numerical value equal to the actual number of windings), a stop signal is issued to the arm operating motor 19, the cord winding arm 16 stops, and the crossing memory 35 stores the crossing characters. It is stored that the user is in the middle of hanging. Thereafter, as shown in FIG.
When the main switch is turned on again by 90 degrees, a rotation signal is issued to the third counter 41 via the memory 35 in the middle of the ten characters, so that the string is operated by the same operation as when the above-mentioned ten characters are not hung. S is wound around the object W to be tied, tied, and cut. In addition,
In the first counter 34, the total number of windings of the cross is set. Regardless of whether it is crossed or crossed, if the tying and cutting machine operating motor 27 is stopped after the operation, the first counter 34 and the second counter 34 are stopped.
The counter 39, the third counter 41, and the cross memory device 35 are reset.
