Further, the main body 1 has a first lower holding member 11.
, A second lower holding member 12, a heater 13, a press member 14, and a lower blade 1 integrally attached to the press member 14.
5 is provided. These members together constitute a sealing mechanism. The second lower holding member 12 includes:
The guide passage 10 is provided movably up and down on the band sending side with respect to the entrance side 10a. The second lower holding member 12 has a guide hole 16 formed therein. Furthermore, the opening edge of the guide hole 16 in the band supply direction front is
7, the lower blade 15 and the upper blade 17 are combined to form a cutter mechanism.

In addition, the second lower holding member 12 has its uppermost non-slip portion 12a at its uppermost position.
The relationship is to be pressed down. To elaborate,
The non-slip portion 12a is made convex,
The upper holding plate 7 is provided with a concave portion 7a that matches the shape of the shape a. The non-slip portion 12a and the concave portion 7a of the upper holding plate 7 constitute a holding mechanism for holding the tip of the band.

The first lower holding member 11 is provided below the upper holding plate 7 at a position facing the outlet side 10b of the guide passage 10 so as to be vertically movable. The first lower holding member 11 rises after the band guide 8 retreats from the band traveling locus. Then, the non-slip portion 11a at the upper end of the first lower holding member 11 presses the lower side of the upper holding plate 7,
Band B at a position corresponding to exit side 10b of guide passage 10
Sandwich. That is, the non-slip portion 11a is formed in a convex shape, and the concave portion 7b that matches the type of the non-slip portion 11a is provided in the upper holding plate 7. The non-slip portion 11a and the concave portion 7b of the upper holding plate 7 constitute a band holding mechanism for holding the band B. Further, the heater 13 can be positioned in the band running locus or retracted to a position deviating from the locus.

The press member 14 is also positioned below the upper holding plate 7 and at a position facing the entrance side 10a of the guide passage 10.
It is provided to be able to move up and down. Press member 1 made in this way
The lower blade 4 is integrally attached to the band 4 so that the band guide 8 moves up after retreating from the band traveling locus.

[0008] Outside the second holding member 12,
A feed roller 18 and an upper roller 19 constituting a band feeding mechanism are provided. Further, a tension arm 20 is provided outside the rollers 18 and 19. The tension arm 20 includes a passage 21 through which the band B passes, a tension jaw 23 that rotates around a pin 22, and a pressing member 24 that forcibly rotates the tension jaw clockwise in the drawing. I have. The tension arm 20 and the tension jaw 2
The tension mechanism is constituted by 3 and the pressing member 24.

Using the packing machine configured as described above, the packing material is banded as follows. First, the band guide 8 is maintained at the raised position as shown in FIG. 7, and the guide hole 16 of the second lower pressing member 12 is opposed to the guide passage 10 of the band guide 8. From the above state, the reel 25
Is pulled out through a pool box (not shown), and inserted into the guide hole 16 and the guide passage 10 through a tension mechanism and a band delivery mechanism. Then, when the feed roller 18 constituting the band feeding mechanism is rotated in the direction of the arrow in FIG. 7, the band B runs at high speed on the bandway 6 of the arch guide 5, and its tip collides with the stopper 9 of the band guide 8. When the band B collides with the stopper 9, the feeding of the band is stopped.

Next, the package W is placed on the tables 2 and 3 in the arch guide 5, as shown in FIG. When the operator presses the start button, as shown in FIG. 8, the second lower pressing member 12 is further raised, and the band B is sandwiched between the non-slip portion 12a and the upper pressing plate 7. When the band B has been pinched in this way, the band guide 8 is retracted from the band traveling locus.

When the band guide 8 retreats from the band running locus, the feed roller 18 is reversed in the direction of the arrow in FIG. 8 to pull the band B. Then, the band B is forcibly removed from the bandway 6 and wound around the package W.

When the band B is wound around the package W, the tension jaw 23 is turned clockwise while being pressed by the pressing member 24 of the tension mechanism, and the band B is firmly held. Then, the tension arm 20 is turned in the direction of the arrow in FIG. 9 to further pull the band B. After the band B is pulled in this manner, the first lower holding member 1
1 is raised to the uppermost position, and the band B is sandwiched between the non-slip portion 11a of the first lower holding member and the upper holding plate 7.

In this state, the front end portion of the band B in the sending direction and the original portion thereof are opposed to each other with a vertical interval therebetween. As shown in FIG.
To dissolve the surface of band B. When the surface of the band B is melted, the press member 14 shown in FIG. 9 is raised, and the melted portion is pressed to bond the two. At this time, since the lower blade 15 provided on the press member 14 also moves up, the band B is cut in combination with the upper blade 17 formed in the guide hole 16. After the band B has been cut in this manner, the upper holding plate 7 retreats from the traveling locus of the band.

[0014]

When the strapping is performed as described above, the package W is strapped together with the upper holding plate 7. In other words, when the package W is banded, the band is always banded with the upper holding plate 7 sandwiched below the package W. Therefore, when the upper presser plate 7 is retracted from the band running locus after the band is mounted, the band hung on the package W is loosened by the amount that the upper presser plate 7 is sandwiched. As described above, when the band B is hung on the package W, no matter how strongly the band B is pulled, there is a problem that the band is loosened by an amount corresponding to the outer dimensions and thickness of the upper holding plate 7 in the band running direction. Was.

In particular, the smaller the package W to be banded, the more loosely the band B caused by the upper holding plate 7 cannot be ignored. This is because the shorter the overall length of the band B to be banded, the higher the proportion of the band B spent on the length corresponding to the outer dimensions and thickness of the upper holding plate 7 in the band running direction. for that reason,
Even if the band is hung, the package easily comes off the band.

Then, even if the outer dimensions of the upper holding plate 7 in the band running direction are to be reduced, the outer dimensions cannot be reduced for the following reasons. Since the concave portions 7a and 7b are provided on the lower left and right sides of the upper holding plate 7, horizontal portions for forming the concave portions 7a and 7b need to be provided at both ends. This is because the concave portions 7a and 7b cannot be formed unless horizontal portions are provided on the surfaces of the concave portions of the concave portions 7a and 7b, which are lower than this surface and on both sides of the concave portion. As described above, it is necessary to provide the horizontal portions at both the left and right ends of the upper holding plate 7, so that the outer dimensions of the upper holding plate 7 have to be increased.

Further, even if an attempt was made to reduce the thickness of the upper holding plate 7, the thickness could not be reduced for the following reasons. Since the upper holding plate 7 is pressed by the first lower holding member 11 and the second lower holding member 12, a certain strength is required. Therefore, the thickness of the upper holding plate 7 cannot be made smaller than a predetermined thickness.

Further, the tip portion of the band B shown in FIG. 9 sometimes leans downward. When the tip of the band B is lowered while the heater 13 is in the band running locus, the band B comes into contact with the heater 13.
Therefore, not only the surface of the band B but also the band B itself may be melted more than necessary. In the worst case, the band B itself is melted, and the tip side of the band B is cut off.

The cause of the tip of the band B dropping is as follows.
This will be described with reference to FIG. The cause of the tip of the band B dropping is the band clamping force between the concave portion 7a of the upper holding plate 7 and the convex portion 12a of the second lower holding member 12. That is, the pinching force acts in a direction in which the tip of the band B is bent downward. Therefore, the tip of the band B easily sags.

An object of the present invention is to provide a packing machine having a clamping mechanism that minimizes the loosening of a band.

[0024]

1 to 3 show a first embodiment of the present invention. Hereinafter, the same components as those of the conventional packing machine are denoted by the same reference numerals, and the description thereof will be omitted. Like the conventional upper holding plate, the upper holding plate 26 can be protruded in a direction crossing the band traveling locus or retracted in a direction away from it. As shown in FIG. 1, the upper holding plate 26 and the first lower holding member 27 constitute a first holding mechanism for holding the band B. The upper holding plate 26 and the second lower holding member 28 constitute a second holding mechanism for holding the band B. Further, a first lower holding member 27 and a second lower holding member 28 are provided below the upper holding plate 26 so as to be vertically movable. Then, the first lower holding member 27 is connected to the upper holding plate 26 by the tension arm 2.
It has a configuration in which the delivery side of the band B extending from the zero side is clamped. On the other hand, the second lower holding member 28 is configured to hold the front end side of the band B spanned over the bandway 6 with the upper holding plate 26.

In FIG. 1, the first lower holding member 27
And the second lower holding member 28 are located near the uppermost position. Further, the band guide 8 and the heater 13 are retracted to a position deviated from the band traveling locus. Furthermore, lower blade 1
The press member 14 provided with 5 is located in an operable state with the lower blade 15 along the second lower pressing member 28.

At the uppermost portion of the first lower holding member 27, a convex portion 27a for preventing slip is provided. As shown in FIG. 1, in the convex portion 27a, the upper holding plate 26 side is defined as an inner inclined portion 27b and the opposite side is defined as an outer inclined portion 27c based on the vertex of the convex portion 27a.

In this embodiment, an inclined portion 26a corresponding to the inner inclined portion 27b is provided below the upper holding plate 26. On the other hand, the upper holding plate 26 has an outer inclined portion 27.
The part corresponding to c is not provided. That is, the upper holding plate 26 of this embodiment has a structure in which the outside of the upper holding plate 26 is cut from a position corresponding to the vertex of the convex portion 27a of the first lower holding member 27. Therefore, when the band B is clamped by the first clamping mechanism, the outer inclined portion 27c is opened. As described above, since the band B is sandwiched between the inner inclined portion 27b of the first lower holding member 27 and the inclined portion 26a of the upper holding plate 26, the band of the upper holding plate is smaller than that of the conventional upper holding plate. External dimensions in the traveling direction can be shortened.

A non-slip portion 28a is provided at the uppermost portion of the second lower holding member 28. In this embodiment, the anti-slip portion 28a is a concave portion. And
A convex portion 26b corresponding to the concave portion of the non-slip portion 28a is provided below the upper pressing plate 26. With such a configuration, the band B is bent by the convex portion 26b of the upper holding plate 26 and the non-slip portion 28a of the second lower holding member 28,
Band B can be strongly clamped.

The reference numeral 26c shown in FIG. 1 denotes a groove in which the stopper 9 enters. When the band guide 8 is in the band traveling locus, the stopper 9 is pressed into the groove 2 of the upper holding plate 26.
6c. Therefore, when the leading end of the band B is sent from the right side in FIG. 1, the band B does not fall out of the gap between the stopper 9 and the upper holding plate 26 to the left. As will be described later, the groove 26c
Is provided closer to the first holding mechanism from the center of the upper holding plate 26, so that the strength of the upper holding plate 26 is not affected.

As described above, the second lower holding member 2
The upper holding plate 26 corresponding to the non-slip portion 28a of FIG.
b. When the convex portion 26b is provided on the upper holding plate 26 in this manner, the horizontal portion is moved to the upper holding plate 3 like a conventional upper holding plate.
6 need not be provided at the outer end. Therefore, the outside of the upper holding plate 26 in the second holding mechanism is cut. Therefore, the outer dimension of the upper holding plate 26 in the band running direction can be shorter than that of the conventional upper holding plate 7.

Further, in the present embodiment, the entire thickness of the upper holding plate 26 is set to the thickness of the concave portion of the concave portion of the conventional upper holding plate 7. This configuration can be made for the following reason. Generally, the upper holding plate needs a certain strength in the vertical direction as described above. In order to secure the strength of the upper holding plate, the concave portion which is weakest against the vertical force needs a certain thickness or more. For this reason, in the conventional upper holding plate 7, the thickness of the concave portion is ensured, and the thickness of the portion other than the concave portion is further increased. As a result, the upper holding plate 7 required a thickness greater than that of the recess as a whole. On the other hand, the thickness of the upper holding plate 26 in this embodiment is entirely the same as the thickness of the concave portion of the conventional upper holding plate 7. And even if it is partially thick like the convex portion 26b, the upper holding plate 26
Can be made thinner than the conventional upper holding plate 7.

With the above-described configuration, in the embodiment of the present invention, the outer dimensions of the upper holding plate in the band running direction can be reduced as compared with the conventional upper holding plate. Further, the thickness of the upper holding plate can be reduced.

In the packing machine using the first holding mechanism and the second holding mechanism having the above-described structure, the package is banded as follows. As with the conventional packing machine, the feed roller 18
Is rotated, and the band B is bridged over the bandway 6 of the arch guide 5. Then, the tip of the band B is brought into a state of reaching the stopper 9 of the band guide 8 shown in FIG.

Next, the package W is placed on the tables 2 and 3 in the arch guide 5. When the operator presses the start button, the second lower pressing member 28 shown in FIG. 1 is raised. Then, the front end side of the band B is held between the non-slip portion 28a of the second lower holding member 28 and the convex portion 26b of the upper holding plate 26. When the band B has been pinched, the band guide 8 is retracted from the band traveling locus.

As described above, the second lower holding member 28
A concave portion is provided in the non-slip portion 28a on the side, and a convex portion 26b is provided on the upper holding plate 26 side. Therefore, the concave portion 28a and the convex portion 26b not only sandwich the band B but also act on the band B as follows.

FIG. 2 is a view showing a second holding mechanism for holding the front end side of the band B. As shown in FIG. 2, when the band B is sandwiched between the concave portion of the non-slip portion 28a and the convex portion 26b, the convex portion 26b of the upper holding plate 26 presses the band B from above. On the other hand, the inclined portions 28b and 28c of the non-slip portion of the second lower pressing member 28 press the band B from below. Therefore, the tip side of the band B indicated by the arrow in the figure is
It will face in the direction along the inclined part 28b. Therefore, the tip side of the band B follows the lower side of the upper holding plate 26. Since the tip side of the band B is along the lower side of the upper holding plate 26, the band B on the tip side is
6 does not hang down.

Next, when the band B has been clamped as described above, the band guide 8 is retracted from the band traveling locus. When the band guide 8 retreats from the band traveling locus, the feed roller 18 is reversed to pull the band B. Then, the band B is forcibly removed from the bandway 6 and wound around the package W.

When the band B is wound around the package W, the band B is pressed by the pressing member 24 of the tension mechanism.
Is turned clockwise to securely hold the band B. And tension arm 2
Turn 0 in the direction of the arrow in FIG. 3 to further pull the band B. Since the tension arm 20 strongly pulls the band B, the non-slip portion 28a of the second lower pressing member 28
It is necessary that the concave portion and the convex portion 26b of the upper holding member strongly sandwich the band B.

With the band B pulled as described above, the first lower holding member 27 shown in FIG. 1 is raised to the highest position, and the inner inclined portion 27b of the first lower holding member 27 and the upper holding plate are raised. The band B is sandwiched by the 26 inclined portions 26a.
Here, the first lower pressing member 27 is pressed against a part of the band B that has been pulled in advance. The pressing of the first lower holding member 27 is for preventing the pulled band B from being loosened. Therefore, the holding force between the first lower holding member 27 and the upper holding plate 26 does not need to be as strong as the holding force on the tip side of the band B. Since it does not require as much force as the clamping force on the tip side of the band B, the inner inclined portion 2
7B and the inclined portion 26a of the upper holding plate 26 can hold the band B.

As described above, the first lower holding member 27
The band holding force between the upper holding plate 26 and the upper holding plate 26 does not need to be as strong as the holding force on the tip side of the band B. Since a strong holding force is not required, the strength of the upper holding plate 26 can be maintained even if the groove 26c for receiving the stopper 9 is provided closer to the first holding mechanism than the center of the upper holding plate 6.

In the state where the band B is sandwiched as described above, as shown in FIG. 3, the front end portion of the band B in the sending direction and the original portion thereof are opposed to each other with a vertical interval therebetween. The heater 13 is inserted into the facing space, and the band B
Melt the surface. At this time, as described above, due to the action of the band holding force between the upper holding plate 26 and the second lower holding member 28, the tip side of the band B does not sag. Since the tip side of band B does not sag, band B
The heater 13 does not come into contact with the heater. Therefore, the heater 13 does not melt the band itself.

As described above, when the surface of the band B is melted, the press member 14 shown in FIG. 3 is raised. At this time, the lower blade 15 provided on the press member 14 also rises,
Together with the upper blade 17 formed in the guide hole 16, the band B on the sending side is cut. Further, the pressing member 14
Presses the melted part. That is, the pressing of the press member 14 bonds the front end portion of the band B in the feeding direction and the original portion thereof. After the band B is bonded in this manner, the upper holding plate 7 is retracted from the traveling locus of the band, and the banding is completed.

As described above, the upper holding plate 26 of this embodiment is
Is thinner as a whole and has a smaller outer dimension in the band running direction than the conventional upper holding plate. Therefore, even if the upper holding plate 26 is banded together with the packaged material W as described above, the looseness of the band after banding can be reduced as compared with the conventional clamping mechanism. In particular,
Even when the packing material W to be banded is small, banding with less loosening of the band can be performed. Therefore, the band does not come off from the banded package.

FIG. 4 shows a second embodiment of the present invention. In the second embodiment, as shown in FIG. 4, a horizontal portion 26d is provided on the band sending side at the base end of the convex portion 26b of the upper holding plate 26 of the first embodiment. The other components are the same as in the first embodiment. As described above, when the horizontal portion 26d is provided on the upper holding plate 26, the horizontal portion 26d and the non-slip portion 28a of the second lower holding member 28 are provided.
Band B can be sandwiched between the outer side of the concave portion. Therefore, the horizontal portion 26d of the upper holding plate 26 and the second lower holding member 28
As a result, the band holding area is widened, and the band B can be held more strongly. Also, even if the horizontal part 26d
As described above, since the overall outer dimensions of the upper holding plate 26 can be reduced as described above, the same effect as in the first embodiment can be obtained.

FIG. 5 shows a third embodiment of the present invention. In the third embodiment, as shown in FIG. 5, the non-slip portion 28a of the second lower holding member 28 is an inclined portion. The other components are the same as in the first embodiment. That is, the non-slip portion 28 of the second lower holding member 28
a and the inclined portion 26e of the convex portion 26b of the upper holding plate 26.
With this configuration, the distal end side of the band B is sandwiched. In the third embodiment, not only the effects of the first embodiment, but also
The following effects can be obtained. If the non-slip portion 28a of the second holding member 28 is formed as an inclined portion, a concave portion may not be formed at the uppermost portion of the second holding member 28. Second
If the concave portion is not formed in the uppermost portion of the lower holding member 28, the outer dimension in the band traveling direction can be reduced, and the second lower holding member 28
Can be reduced.

[0046]

According to the first invention, the band sending side is sandwiched between the inclined portion provided on the upper holding plate and the convex portion provided on the uppermost portion of the first lower holding member. The provided protrusion,
The front end side of the band is sandwiched by the slip stopper provided at the uppermost part of the second lower holding member. With this configuration, the outer dimensions of the upper holding plate in the band running direction can be made shorter than the conventional upper holding plate, and the thickness thereof can be reduced. Therefore, loosening of the band after banding on the package can be minimized. In addition, the tip side of the band can be arranged along the lower side of the upper holding plate. Therefore, the tip side of the band does not sag downward. Since the tip side of the band does not sag, the heater does not contact the band and melt the band itself.

According to the second aspect of the invention, the band is bent by the second lower holding member and the upper holding plate to hold the band. Therefore, the band can be strongly held. According to the third aspect of the invention, the band front end is sandwiched between the inclined portion of the second lower holding member and the convex portion of the upper holding plate. Since the second lower holding member sandwiches the upper holding plate and the band at the inclined portion, the outer dimensions of the second lower holding member in the band running direction can be reduced.

According to the fourth aspect of the present invention, the holding area between the second lower holding member and the upper holding plate on the tip side of the band is increased. Therefore, the holding force of the band can be further increased.
