[0002]

2. Description of the Related Art There is a binding wire used for binding the mouth of a bag such as a mesh bag or a bundle of rods, and there is a binding structure mechanism for automatically binding using the binding wire. As such a binding structure mechanism, a mechanism shown in FIG. 15 is conventionally known (Japanese Patent Laid-Open No. 10-230908). That is, in the binding structure mechanism 200, the lower substrate 201, the spacer 202, the intermediate substrate 20
3. A laminated substrate body 206 obtained by integrally laminating a spacer 204 and an upper substrate 205 is used as a basic component, and a bay-shaped insertion portion is formed from the peripheral side of the laminated substrate body 206 toward the inside. A notch 207 is formed. When the binding object 208 is inserted into the insertion portion 207, both ends of the binding wire 210 fed from the reel 209 are twisted by the twisting means 211 and the binding object 208 is twisted.
Are bound by a binding wire 210.

Prior to the binding object 208 being bound to the binding wire 210, the binding wire 210 introduced into the binding structure mechanism 200 is cut into a predetermined length by a cutting means 212, The binding object 2 by the addressing means 213
08, and their free ends are rotationally locked by the rotation locking member 214 of the twisting means 211 and twisted. The torsion means 211 is provided on a driven gear 216 meshing therewith from a drive source 215, a rotation shaft 217 of the gear 216, a power transmission means 218 mounted on the rotation shaft 217, and the power transmission means 218. Spur gear 219 and gear 220 meshing with the spur gear 219

[0004]

The binding structure mechanism 2
00 theoretically exhibits the binding function of the binding object 208, but it has been found that the following points need to be improved in actually using the binding structure mechanism 200.

First, the laminated substrate body 206 of the binding structure mechanism 200 is composed of five layers of a lower substrate 201, a spacer 202, an intermediate substrate 203, a spacer 204, and an upper substrate 205. In many cases, work such as assembling and positioning adjustment becomes complicated. Further, since all of the constituent members are made of a metal plate, the space between the lower substrate 201 and the intermediate substrate 203 secured by the spacer 202 or the space 20
4 and the intermediate substrate 203 and the upper substrate 205 formed by
Operating means incorporated in the space between the reels 209, ie, the feeding roller 221 for feeding the binding wire 210 fed from the reel 209, the cutting means 212, and the addressing means 21.
3 and operating means such as twisting means 211 and spacer 202;
The frictional resistance with the actuator 204 becomes an obstacle, and the smooth operation of the operating means in the space cannot be ensured. If the assembling accuracy is not increased, the variation increases, and it takes time to adjust the position.
There is a manufacturing problem that the production efficiency of the binding machine cannot be increased. Further, a failure is easily caused.

Further, in the conventional binding structure mechanism 200, when the binding wire 210 cut to a predetermined length is applied to the binding object 208 from the back side to the front side,
Since the addressing means 213 bends the binding wire 210 into a hairpin shape and locks it with the rotation locking member 214 of the twisting means 211, the binding wire 21 for the binding object 208 is bent.
There is a problem that the binding of 0 becomes loose. This problem is not caused by the conventional iron core binding wire, as shown in FIG.
This is particularly noticeable when the core wire 222 embedded in the binding wire 210 is made of a synthetic resin filament. This is because the synthetic resin filament has a certain degree of elasticity, so that it is not only difficult to bind, but even if it is once bound and deformed to some extent, the residual strain of the synthetic resin filament acts as time passes and the binding becomes tight. This is because they come loose.

On the other hand, the above problem can be alleviated by using a binding wire in which a metal core wire 222 is used as the conventional binding wire 210. However, when the used binding wire 210 is discarded or recycled, it is combined with a metal part. The separation is difficult because of the presence of the resin part. Therefore, the use of the binding wire 210 in which the synthetic resin wire is used as the core wire 222 is inevitable. But,
If it is used, it is necessary to make the binding of the binding wire 210 to the binding object 208 more reliable and stronger than the binding by the conventional binding machine.

Accordingly, the present inventor has conducted intensive studies to propose a binding structure mechanism capable of solving the above-mentioned problems. As a result, the material, shape, and structure of the intermediate substrate of the laminated substrate, which is a main element of the binding structure mechanism, have been studied. And the fact that it is sufficient to improve the binding state of the binding wire at the stage of being locked by the twisting means, and the fact that the twisting means and the like may be improved, and completed the present invention. Therefore, an object of the present invention is to reduce the number of parts of the binding structure mechanism, to facilitate the assembly of the mechanism, and to smoothly operate various operating means mounted on the mechanism, so that the binding structure The purpose is to ensure that the function of the mechanism is exerted.

[0009]

According to a first aspect of the present invention, there is provided a binding structure mechanism 4 comprising a synthetic resin intermediate substrate (60) disposed between a metal lower substrate (10) and a metal upper substrate (60) superposed thereon. 30), a substrate laminated structure (9) obtained by integrally laminating the three substrates, and a tied notch formed in the substrate laminated structure in a bay shape from the peripheral side toward the inside.

Also, when twisting, hold down the object to be tied to the base of the insertion portion, and twist the two free ends of the binding wire near the both ends by the twisting means in the next stroke,
Even when a binding wire in which a synthetic resin filament is embedded in a core material is used, an object to be bound can be firmly bound.

In the sixth aspect of the present invention, the two ends can be expanded by inserting a twisting means between the two ends when the middle is brought close to the front side. By expanding the both ends, the twisting by the twisting means is ensured, and the binding wire can be twisted more firmly. As shown in the seventh invention, a holding member (74) for holding the object to be bound inserted into the insertion portion from the back side is provided, and the holding member is provided immediately before cutting the binding wire by the cutting means.

At the same time, the distance between both ends of the binding wire can be increased by the twisting means. The twisting means may be any means as long as the binding wire can be twisted. As shown in the ninth invention, the twisting means includes a substantially S-shaped rotation locking member 92, Both ends of the S-shape 92 are bent toward the object to be bound. By using such a twisting means, the binding wire can be reliably grasped,

Next, the lower substrate 1 laminated as described above
0, to drive the operating means such as the feed rollers 81a and 81b, the cutting means 82, the addressing means 85 and the twisting means 88 incorporated between the middle substrate 30 and the upper substrate 60,
The driving force can be directly transmitted from a plurality of driving sources to them, and they can be controlled by electronic control means. In this embodiment, the mechanical control means is used from one driving source. In addition, a technique is employed in which the mechanical control means is partially or entirely provided with a power transmission means. To explain this in detail,
First, as described above with reference to FIG. 1, the motor 70 is installed as the drive source in the housing 3 of the binding machine 1. The rotation of the motor 70 rotates the gears 99 with respect to a rotation shaft 98 inserted into the laminated substrate structure 9 including the lower substrate 10, the middle substrate 30, and the upper substrate 60.
a, 99b. As shown in FIGS. 5 and 6, a cam 75 is externally inserted and a pin 104 is inserted in a diametric direction in the middle of the rotating shaft 98. Therefore, when the rotating shaft 98 rotates, the cam is also moved. It is designed to rotate. Further, as shown in FIG. 7, at the tip of the rotating shaft 98 projecting upward from the upper substrate 60,
A multi-function gear body 100 having various control functions is mounted as the mechanical control means. When the rotation shaft 98 rotates, the multi-function gear body 100 also rotates. Therefore, in this embodiment, the rotation of the motor 70 as the driving force of the binding structure mechanism 4 according to the present invention is transmitted via the rotation shaft 98 and the transmission means such as the cam 75 and the multi-function gear body 100. Is transmitted to the operating means.

The multifunctional gear body 100 made of synthetic resin is:
As shown in FIG. 8, the appearance is such that three disks are superimposed, and is composed of an upper disk portion 101, an intermediate disk portion 102, and a lower disk portion 103. The uppermost upper disk portion 101 controls the rotation of the feed rollers 81a and 81b, and is mounted on the same rotary shaft 81c as the main roller of the feed roller 81a at a predetermined interval. And slides in contact with the geared roller 105. Therefore, the upper disc 10
As shown in FIG. 9, a partial gear portion 101a in which a gear is partially cut is provided on the outer peripheral surface of the gear 1 so that the gear portion 105a can be engaged with the gear portion 105a located below the roller 105 with the gear. ing. In addition, an annular projection 101b whose diameter is slightly reduced from the outer peripheral surface is provided on the upper surface, and the outer periphery of the annular projection 101b can be slidably contacted with the chipped roller portion 105b located above the geared roller 105. (See FIG. 7). The portion of the annular projection 101b that overlaps the partial gear portion 101a in the radial direction is smaller in diameter than other portions.

An intermediate disk portion 102 integrally formed directly below the upper disk portion 101 has a function of controlling ON / OFF of a limit switch 96 with respect to the pressing lever 95, as shown in FIG. , A semi-circular protrusion 102a is formed on the outer peripheral surface. The lowermost lower disk portion 103 is provided with the twisting means 88.
11 has a function of controlling the rotation and stop of the flat teeth 1 arranged radially on the lower surface along the peripheral surface as shown in FIG.
03a is a spur gear provided about half a circumference, and the spur tooth 10a is provided at a portion where the spur tooth 103a is interrupted.
It has a flat sliding contact surface 103c whose diameter is larger than 3a, and further has an arc-shaped projection 103b extending outward in an arcuate surface on the sliding contact surface 103c.

Next, the cam 75 and the multifunctional gear body 10
0 will transmit the rotational energy of the motor 70, which is the drive source, to the actuating means in detail.
First, the case of the cam 75 will be described. The binding wire 7 is passed through the guide groove 35 and the through hole of the fixed blade 84b of the cutting means 82 in advance. Then, as described above, the three insertion portions 11, 3
When the object to be bound 8 is inserted into the lamination insertion portion in which the first and the 61 have the same bay-shaped lamination surface, the switch lever 94 and the pressing lever 95 are displaced to turn on the limit switch 96, and the motor as the driving source is driven. 70 starts. Then, the rotation shaft 98 rotates, and as shown in FIGS.
Rotates in the direction shown by the arrow B, and the outer peripheral surface 75a of the cam 75
Contacts the inner peripheral surface 73b of the second sector gear member 73. The installation position of the rotation support shaft 46 of the second sector gear member 73 and the two peripheral surface shapes are determined in advance by design so that the partial gear 73a of the second sector gear member 73 rotates in a predetermined range. And the second sector gear member 73
Rotates within a predetermined range shown in FIGS. 5 and 6.

Then, the first sector gear member 71 meshing with the second sector gear member 73 also rotates within a predetermined range. That is, the tip makes an arc motion in the rotation hole 32.
A pair of rotating shafts 72a, 7
2b projecting therefrom, and their rotation support shafts 72a, 72
The opening and closing members 86 and 87 that are pivotally supported by b also displace,
Since the sliding protrusion 86d is provided on the opening / closing member 86, the displacement trajectory of the sliding protrusion 86d is restricted by the rotation regulating hole 67 of the upper substrate 60 as shown in FIGS. While the sliding projection 86d moves from the point P shown in FIG. 7 to the point Q, the entire opening and closing member 86 is moved in the direction shown by the arrow C shown in FIG.
Go to Further, when the sliding projection 86d moves from the point Q shown in FIG. 7 to the point R, the opening / closing members 86 and 87 close, and the grips 86a and 87a are moved to the back of the object 8 as shown in FIG. From the side to the front side, the middle of the binding wires 7 near both ends is brought close to each other on the front side, so that the object to be bound is surrounded without slack. The free end of the binding wire 7 opens outward because the rotation locking member 92 is located therebetween. At that time, the rotation locking member 9 of the twisting means 88
The object 2 is tightly bound by the binding wire 7 because the 2 locks the free end and twists. By performing such an operation, the resin core binding wire 7 having less flexibility than the iron core.
Even though it can be tightly bound.

As described above, the first sector gear member 71 is
When rotated in the direction of arrow C in FIGS.
The pressing member 74 is rotated by a spring to push the object 8 to the twisting means 88 side. At the same time, the pressing peripheral surface 71b of the first sector gear member 71 is
The third locking projection 83a is pushed toward the front side of the intermediate member 30. Then, the cutter slide 83 rotates to move the movable blade 8.
4a is advanced. As a result, the binding wire 7 is cut into a predetermined length, which is used when binding the objects 8 to be bound. When the first sector gear member 71 rotates in a direction opposite to the above-described direction, the pressing peripheral surface 71c in a positional relationship opposite to the pressing peripheral surface 71b presses the locking projection 83a.
The cutter slide 83 rotates in a direction different from the above, and the movable blade 84a is retracted.

On the other hand, when the rotating shaft 98 rotates in the direction of the arrow B shown in FIG. 7 as described above, the multi-function gear body 100 mounted on the upper part thereof, that is, the upper disc part 101,
The intermediate disk part 102 and the lower disk part 103 rotate simultaneously. Since the geared roller 105 is in contact with the upper disk portion 101, the partial gear portion 101a of the upper disk portion 101
Is rotated and the gear portion 105a of the geared roller 105 is rotated.
And the feed roller 81a sharing the rotation axis 81c with the other roller 81
The binding wire 7 is advanced in cooperation with b. Upper disk part 101
Continues to rotate as it is, and eventually the partial gear portion 101a
Therefore, the chipped roller portion 105b of the geared roller 105 enters a non-rotating state while maintaining a sliding contact state with the outer peripheral surface of the annular protrusion 101b of the upper disk portion 101 that continues to rotate. When the chipping roller portion 105b enters the non-rotation state, the rotation of the feed roller 81a that is mounted on the rotation shaft 81c coaxial therewith stops, and the feeding of the binding wire 7 to the binding structure mechanism 4 stops.

As shown in FIG. 10, the intermediate disk portion 102 is provided with a projection 102a, and during the rotation of the intermediate disk portion 102 (just before the end of all the steps), the pressing lever 9
5 is pushed in the direction indicated by arrow E in FIG. Thereby, the tip of the pressing lever 95 is separated from the leaf spring 96a. Accordingly, even if the pressing lever 95 is pressed by the binding object 8,
When the binding is completed, the limit switch 96 can be turned off, so that the same binding object 8 can be prevented from being erroneously bound to the same binding object 8 many times. Further, when the pressing lever 95 presses the leaf spring 96a, the lock member 97 locked by the tip of the leaf spring 96a also moves by the spring 97c, and presses the leaf spring 96a. Further, the lock member 9
7 is an arc-shaped projection 103b at the time when all the steps of binding are completed.
7 in the direction indicated by arrow E in FIG.
Move away from a. Thereby, even if the pressing lever 95 is separated from the leaf spring 96a, the leaf spring
Can be prevented from returning to the original position. Also,
When the binding is completed, the limit switch 96 can be turned off, and it is possible to prevent the binding from being performed repeatedly by mistake.

The lower circular arc portion 103 has a spur tooth 103a on the lower surface thereof for about half a circumference and a sliding contact surface 103c having an enlarged diameter on the remaining lower surface. The latter meshes with the sliding wheel 90 in sliding contact. Accordingly, when the lower disk portion 103 rotates, the spur teeth 103a shown in FIG. 4 come into contact with the gear 89 of the twisting means 88 shown in FIG. 4, and the rotation locking member 92 is rotated to bind the binding wire addressed thereto. Twist 7. When the meshing of the gears is completed, the sliding contact surface 103c and the sliding wheel 90 are only in sliding contact, and the rotation of the rotation locking member 92 is stopped.

The laminated substrate structure 9 configured as described above
A bearing substrate 108 as shown in FIG. 13 is mounted on the multifunctional gear body 100 by externally inserting the rotary shaft 98 into a bearing 108a provided on the bearing substrate 108, and a spacer and a male screw (neither shown). As a result, the binding structure mechanism 4 according to the present invention is completed by screwing with the female screw 38 of the holding portion 39 provided on the back surface side of the intermediate substrate 30.
00 and the geared roller 105
As shown in FIG. 8, an elastic material 109 is inserted between the bearing substrate 108 and the multi-function gear body 100 in order to maintain good engagement with the gear. The elastic member 110 is also inserted between the upper substrate 60 and the multi-function gear body 100. As the elastic members 109 and 110, materials, materials and shapes that achieve the above-mentioned objects can be used. As an example, stainless steel or the like suitable for a leaf spring is used, the elastic member 110 has a disk shape, and the elastic member 109 has a circular shape having an arbitrary number of radial cuts as shown in FIGS. ,
The longitudinal section can be frusto-conical or other shapes.

The individual controls described above include the supply of the binding wire 7 to the binding structure mechanism 4 according to the present invention, the insertion portion 11,
Insertion of the material 8 to be tied into 31, 31
The multi-function gear body 100 and the like are programmed so that the above-described series of steps, such as the assignment of the binding wire 7 and the twisting of the binding wire 7 can be smoothly performed with no waste and with an organic relationship. In addition, since the rotating shaft that takes in the driving force of the motor 70 is provided through a resin gear,
Even if the motor 70 experiences an electric leakage, it does not leak to the binding structure mechanism 4 and an electric shock accident can be prevented. Further, the upper substrate 60 and the lower substrate 10 are made of metal, and the intermediate substrate 30 is made of synthetic resin, thereby facilitating assembly.
The errors due to warpage and the like can be reduced, and the binding mechanism can be simplified.

Further, as shown in FIG. 12, at the time of binding, the object 8 to be bound is previously held down by the holding member 74, and the binding wire 7 is wound around the opening and closing members 86 and 87 without slack and the root is held down. Core wire 222
Even if the binding wire 7 is made of, it is tightly bound and does not loosen. Also, by increasing the distance between both ends of the binding wire 7,
It can be easily inserted into the groove 922 of the rotation locking member 92 and can always be twisted with a constant force.

The present invention is naturally permitted to be modified and implemented in a part of the above-described embodiment within the limits of the basic technical idea and without significantly impairing the effects of the invention. For example, the control system can be flattened by changing the shape or structure of the rotation locking member, or by changing the mechanical control means to an electronic control means having a plurality of sensors and a drive source. In order to make the binding machine itself compact, a reel 6b can be provided on the side surface of the housing 3 as shown in FIG. In this embodiment, the side surface of the housing 3 is slightly retracted inward so that the reel 6b can be installed vertically below the guide piece 33 of the intermediate substrate 30, and the reel 6b is formed to protrude rotatably from the side surface. Various reel mounting structures can be employed, such as allowing the mandrel 6e to support the reel 6b in a cantilever manner and fixing the brake arm 6c to the rear portion of the housing 3. Furthermore,
As shown in FIG. 18, a cover 6g is provided on the reel 6b and the like.
To improve the appearance and safety.
