Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for detecting bundling defects in a bundling machine.

In particular, with unmanned high-speed fully automatic binding machines, the discovery of poorly bound objects is delayed, resulting in piles of poorly bound objects, and as a result, subsequent production lines must be stopped to dispose of the bound objects. There was a problem that could not be solved.

The present invention provides a method and apparatus for detecting bundling defects that solves the above-mentioned problems by immediately detecting improperly bound objects.

That is, the present invention lowers the movable claw to approach or contact the object to be bound, binds the object and the object together with a string, and then lifts the object to ensure that the string is tied well. A method for detecting poor bundling, in which the thread is detached from the string, and when the string is poorly tied, the thread rises as it is and issues a signal of poor bundling, and a guide that can be raised and lowered. , a reciprocating body elastically supported so as to be guided by the guide so as to be movable up and down and pushed down, and provided with a pin projecting laterally; and a claw plate attached to the guide so as to be movable around the guide. The reciprocating member is fitted with a pin of the reciprocating body, and when the pin is in the upper position, a claw provided at the lower end is rotated forward, and when the pin is in the lower position, the reciprocating body is formed so that the claw can move backward at the same time. a bundling defect detection device having a long hole, and a signal generator that emits a signal of bundling defect when the guide rises while the guide is rotated forward, and a guide that can be raised and lowered; a claw plate that is rotatably attached to the guide and is configured such that when the claw provided at the lower end is rotated forward, the backward rotation recovery layer is stopped until a certain load is applied to the claw; Each of the present invention provides a bundling defect detection device including a signal generator that emits a signal indicating a bundling defect when the guide rises while the guide is rotated forward.

The method of the present invention will be explained below based on an example of an implementation apparatus.

The device of the present invention shown in FIGS. 1 to 8 comprises a guide 10, a reciprocating body 20, a claw plate 80, a signal generator 40, and an abutment rod 60. The guide 10 consists of a frame 101 with a cross-sectional shape closed with a lid 102, and a clamping member that moves up and down is attached to a brace 60 via a bracket 11 so that it can move up and down. The reciprocating body 20 is constructed by fixing a protruding bar 28 protruding upward to a square column 22 having protrusions 21 on opposing surfaces, and also fixing a pin 24 protruding laterally to the vertical groove 108 of the guide lO. Each protrusion 21 is fitted to guide the guide 10 so that it can move up and down, and the lid 102 of the guide 10 and the prism 2
It is elastically supported so as to be pushed downward by a coil spring 25 which is interposed at the top and surrounded by a protruding rod 28. Further, the reciprocating body 20 is formed such that the bottom plate 221 attached to the prism 22 is located below the lower surface of the brace 60. The claw plate 80 is rotatably attached to the bracket 11 fixed to the guide 10 via a pin 81 and has an elongated hole 82 that fits into the pin 24 of the reciprocating body 20.
is provided. The elongated hole 82 has the pin 24 in the upper position 24.
When the pin 24 comes to the lower end of the nail plate 80 (a), the pawl 801 provided at the lower end of the pawl plate 80 is rotated forward, and when the pin 24 comes to the lower part 11124 (b), a hole shape is formed in which the pawl 801 is moved backward at the same time. ing.

The signal generator 40 is connected to the guide lO via a bracket 41.
When the protruding rod 2g (b) of the reciprocating body 20 comes to the upper 1112B (roll), it contacts (or comes close to) this, and when the contact (or proximity) time elapses for a certain period of time, a signal ( (for example, an alarm). The signal generator 40 also includes a fixed frame 6 into which a rod 61 of a brace 60 that moves up and down is fitted, as shown by imaginary lines.
2 and is in the upper position 28(a).
The signal generator 40 may be raised together with the guide 1G and immediately issue a signal indicating a failure in the beam flux when it approaches or comes close to the fog, and the signal generator 40 may be attached to the stand 90.

Further, the signal generator 40 detects the movement of the claw plate 30 when the claw 801 is rotated forward and rises together with the guide.
．． A phototube device (detected by the protruding rod 28 or guide 10, etc.)
(not shown) or a proximity switch device (not shown).

The contact rod 60 is pressed down by the fixed frame 62 according to the holder 62 and hits the claw 801 that has risen together with the guide 10, so that the claw 801 can be rotated back. 7. The abutting keyaki 50 may be a simple rod (not shown) fixed to the fixed frame 62 or the stand 90 or the like.

Next, the method of the present invention will be explained based on the above-mentioned apparatus example.

In the above device example, the objects to be bound 7 that have not yet been bound
0 is tightened to some extent by the descending press 60 (the tightening operation may not be necessary). At the same time, reciprocating body 2
Since the bottom plate 221 of 0 hits the object to be bound 70 and is pushed up, the pin 24 moves from the lower position 24(b) to the upper position 24(a).
), and the claw 801 is rotated from the rear to the front. The claws 801 that have been moved forward are in a state where they are close to or in contact with the object to be bound 70, and in this state, a binding machine (not shown) is activated to bind the claws 801 and the object to be bound 70 together with the string 80. ζ
Band together. When the binding is completed, the claw 801 is raised together with the brace 60 and the guide 10, and when the string 80 is tied well, the claw 801 is pushed by the weight of the object 7G through the string 80 and moves from the front to the rear. However, if the string 80 is poorly tied, the claw 801 will continue to rotate forward and rise.
During this time, the protruding rod 28 of the reciprocating body 20 remains in the upper position 28 (rotation) for a certain period of time, so the signal generator 40 issues a signal indicating poor bundling. Since the contact rod 50 is pressed down and hits the claw 801, and the task is repeated, a string that is poorly tied during tying will be immediately detected.

Another example of the apparatus of the present invention is shown in FIGS. 4 and 6. Jin's example device consists of a guide IOB, a claw plate 8OB, and a signal generator/contact rod 45. The guide 10B is shaped like a square plate, and is provided with a limit switch L that can be moved up and down and comes into contact with the guide 80B. The claw plate 80B is the guide IOB
A compression coil spring 84 is attached between the pin 88 which is rotatably attached to the pin 81B near the lower end and the pin 18 fixed to the guide IOB, and rotates the claw 801B provided at the lower end rearward. I can do it, vibe 8
A cap $6 is fitted to the threaded surface of the pipe 85, and a compression coil spring 87 is inserted into the pipe 85 with one end pressed against the inner surface of the cap 86 and the other end pressed against a ball 871. The ball 871 presses against the recess 14 provided in the guide IOB.

The signal generator and contact rod 46 consists of a contact rod 452 provided at the tip of an arm rod 91 attached to the stand 90 and a push button (switch) 451 fitted inside the contact rod 452. is electrically connected to an alarm (not shown).

A further example of the device of the present invention is shown in FIG. Jin's example device includes a guide 100, a claw plate 80C, and a signal generator/contact rod 4b. The guide 100 is shaped like a square plate, and is connected to a lifting rod 610 that can be raised and lowered. Further, a strong magnet 15 is attached to the guide 100 so that it can be magnetically attached to a magnetic plate (not shown) on the upper part of the claw plate 800. Furthermore, the guide 100 includes a mold 8010 described later.
A limit switch L is provided that comes into contact with the claw plate 800 as the lever rotates forward. The claw plate 800 is rotatably attached to the guide 100 via a pin 810, and the lower part is made to be heavier than the upper part so that the claw 801C provided at the lower end can move backward at the same time. .

The signal generator/contact rod 46 is the same as described above.

The method of the present invention will be explained based on the machine number ζ No. 4 and the apparatus examples shown in FIGS. 5 and 6.

Guide IO for the objects to be bound 70 that have not been bound yet.
B or 100 descends and the claw 801B or! 1010, the claw 801B or 801C rotates forward while sliding on the object to be bound 70, and the claw plate 80B or 300 contacts the pin 8.
The guide 10B or 100 rotates around Sta and hits the limit switch L, so the lowering of the guide 10B or 100 is stopped.

In this state, the tying machine (not shown) is activated to tie the string 80.
The claw 801B or 8010 and the object to be bound 70 are bound together. Once the binding is complete, remove the claw 80 along with the guide IOB or 100.
When 1B or 8010 is raised, when the string 80 is well tied, it overcomes the resistance of the ball 871 against the claw 801B or 8010, or overcomes the magnetic force of the magnet 88, and rotates back to the rear.

When the string 80 is tied poorly, the pawl 801B or goio moves forward and rises, hits the push button 451 of the signal generator/contact rod 46, and issues a signal indicating poor binding, and is activated by the abutment rod 452. It is pushed down and rotates back from the front to the rear, making it possible to immediately detect poorly tied strings.

According to the method of the present invention, defective bundling can be detected reliably, easily and quickly, and the device has the advantage that it can be manufactured easily and inexpensively.
