JP-A-6-115775

As described above, in the apparatus disclosed in Patent Document 1, the feeding of the belt-like object is stopped during the connection. For example, a packaging device that wraps an article using the belt-like article is several ten meters per minute. If a belt-like object is consumed and the feeding of the belt-like object is stopped for about 10 seconds for the connection of the belt-like object, an accumulation of several meters is required.
For this reason, there is a problem that the accumulating means becomes larger and more complicated, and the belt-like material is sent while being meandered delicately. There was a risk of damage or damage.
On the other hand, when a heating roller and a counter roller that are freely rotatable are used and the belt-like object is sandwiched by heating without being stopped, the belt-like object cannot be heated sufficiently. There was a problem that the material was insufficiently pressed and easily peeled off.
In order to solve this problem, it is conceivable to reduce the feeding speed only during the connection, but eventually the supply capacity of the belt-like material is lowered and the amount of accumulating is increased.
In view of such a problem, the present invention provides a strip connection device capable of solving the above-described problem by suppressing a decrease in the supply capability of the strip due to the connection operation as much as possible.

That is, the belt-like object connecting device of the present invention includes a heating roller whose outer peripheral surface is heated by the heating unit, a counter roller disposed to face the heating roller, and a moving unit that moves the heating roller and the counter roller closer to and away from each other.

When a plurality of the opposing rollers are provided and are sequentially arranged in the conveying direction of the strip, and the opposing rollers and the heating roller are brought close to each other, the opposing rollers pass the strip over the required range of the outer peripheral surface of the heating roller. The belt-shaped object is heat-pressed by at least one opposing roller and a heating roller.

According to the above invention, when the belt-like object is connected, the belt-like object is brought into surface contact over the required range of the outer peripheral surface of the heating roller by each opposing roller. Even in a portion other than the opposing roller, the belt-like object can be heated.
As a result, it is possible to shorten the time for heat-pressing the band-like material, and to suppress the decrease in the supply capability of the band-like material accompanying this.

The cutter 28a is also movable up and down and left and right by the air cylinder 27a, like the suction portion 24a.

As shown in FIGS. 1 and 2, the connecting means 15 is a heating roller located on the right side across a belt-like object 2 </ b> A drawn directly below the new roll 2 loaded on the roll support shaft 12 at the center position. 31 and first to third opposing rollers 32 to 34 positioned on the left side, and the heating roller 31 and the first to third opposing rollers 32 to 34 are moved closer to and away from each other by the moving means 35. ing.
Here, the new strip 2A that has been drawn out and the strip 2A that is being used have the adhesive-coated surface facing the first guide roller 23A, that is, the left side in the figure, and the heating roller 31 is bonded. It comes in contact with the uncoated surface of the agent. This prevents the adhesive melted by heating from adhering to the surface of the heating roller 31.
The heating roller 31 is a cylindrical member rotatably provided on the support member 36. The outer peripheral material is aluminum and incorporates a heater 31A as heating means.
The heater 31A can heat the outer periphery of the heating roller 31 to about 250 ° C., and the heating roller 31 heats the strip 2A to dissolve the adhesive of the strip 2A.
The heater 31A is not used except when the strip 2A is connected, and is not normally heated. The heater 31A is operated based on the remaining amount of the roll 2 in use so as to reach a predetermined temperature when connected. It has become so.
Next, the first to third counter rollers 32 to 34 are rotatably provided on a mounting stay 38 via a plate-like support plate 37, and each is a cylindrical member having a smaller diameter than the heating roller 31. ing.
Each support plate 37 is provided with an oval adjustment hole 37a, and a bolt 38a is inserted into the adjustment hole 37a to fix the support plate 37 to the mounting stay 38. Along the adjustment hole 37a, the support plate 37 is fixed. By moving the support plate 37, the relative positions of the first to third opposing rollers 32 to 34 in the left-right direction can be adjusted.

These first to third counter rollers 32 to 34 are provided in the order of the first counter roller 32 to the third counter roller 34 in the conveying direction of the strip 2A, that is, the vertical direction, and the outer circumferences of the respective counter rollers 32 to 34. The surface is disposed so as to face the outer peripheral surface of the heating roller 31, and the band-like object 2A in use and the new band-like object 2A are positioned therebetween.
The outer peripheral material of the first and second opposing rollers 32 and 33 is aluminum, and the outer peripheral material of the third opposing roller 34 is silicon rubber. The third opposing roller 34 is a belt-like material. When 2A is pressed, its surface is elastically deformed.
Further, the moving means 35 is fixed to the main body 11 and guides the support member 36 and the mounting stay 38 in the left-right direction, and the support member 36 and the mounting stay 38 are guided along the guide rails 39a and 39b. Air cylinders 40a and 40b that reciprocate are provided.

The accumulator 16 includes a slide shaft 41 provided in the vertical direction on the main body 11, a slide member 42 that moves up and down along the slide shaft 41, a dancer roller 43 that is rotatably supported by the slide member 42, The slide member 42 includes a spring 44 that biases the slide member 42 upward.
Below the slide shaft 41, a guide roller 45a for guiding the belt-like object 2A connected by the connecting means 15 to the dancer roller 43, and a belt-like object 2A accumulated by the dancer roller 43 are supplied to a packaging device (not shown). A guide roller 45b is provided, and a predetermined amount of the belt-like object 2A is pulled out and accumulated between the guide rollers 45a and 45b.
The slide member 42 is positioned above the slide shaft 41 by the urging force of the spring 44 while the strip 2A is being conveyed in a normal state, but the supply of the strip 2A from the upstream side is stopped. When the feed rate is temporarily reduced due to the lowering of the feed speed, the slide member 42 is pulled down against the urging force of the spring 44 by the pulling action from the downstream side, and is accumulated accordingly. The belt-like object 2A is drawn out.

Next, the rollers 31 to 34 in the connection means 15 will be described with reference to FIG. 2. In FIG. 2, the heating roller 31 and the first to third opposing rollers 32 to 34 are moved closer to each other by the moving means 35. The state which has connected the new strip | belt 2A to the strip | belt 2A in use is shown.
In this state, the heating roller 31 is advanced in a direction orthogonal to the new belt 2A that is drawn out and hangs down, and the advance position abuts on the belt 2A and further advances further to the belt 2A is a position to push forward.
On the other hand, the first and second opposing rollers 32 and 33 are vertically arranged so as to be substantially line symmetrical with respect to a horizontal line passing through the rotation center of the heating roller 31 when viewed from the front as shown in the figure. Is arranged.
In the state of FIG. 2, the second opposing roller 33 heat-presses the two strips 2 </ b> A with the heating roller 31, and the interval between the first opposing roller 32 and the heating roller 31 is the second opposing roller 33. And the heating roller 31 are set to be wider.
For this reason, the first opposing roller 32 is sandwiched between the heating roller 31 so as not to press the two strips 2 </ b> A.
Further, the third counter roller 34 is arranged further downstream of the second counter roller 33 in the transport direction of the belt-like object 2A, and the third counter roller 34 is in contact with the heating roller 31 with its surface elastically deformed. By sandwiching the two strips 2A between them and elastically deforming them, the belt 2A is in pressure contact with the heating roller 31 in a wide range.
In other words, the positions of the first to third counter rollers 32 to 34 in FIG. 2 are defined as a position where the second object roller 33 and the heating roller 31 sandwich the belt-like object 2A as a thermocompression bonding position P. When the tangent line L in the heating roller 31 passing through P is drawn, the positions of the outer peripheral surfaces of the first opposed roller 32 and the third opposed roller 34 protrude from the tangent line L toward the heated roller 31 side.

According to the configuration of the present embodiment described above, when the opposing rollers 32, 33, 34 and the heating roller 31 are brought close to each other, the belt-like object 2A in use and the new belt-like object 2A are Between the first opposing rollers 32, both are in a state of approaching the outer peripheral surface of the heating roller 31.
On the other hand, between the heating roller 31 and the second counter roller 33, the two strips 2A are pressed so as to press each other, and the range from the first counter roller 32 to the second counter roller 33 is reached. Then, it is curved along the outer peripheral surface of the heating roller 31 so as to cover it.
In this curved section, any of the strips 2A, that is, the strip 2A in use on the left side in FIG. 2 and the new strip 2A in the new strip 2A at the center, or the right side shown by the two-dot chain line The band 2A in use in the band 2A in use and the new band 2A in the center come into surface contact with the outer peripheral surface of the heating roller 31 over a predetermined range in this section.
In this surface contact state, the strip 2A is heated, and the adhesive coated on the surface opposite to the surface in contact with the heating roller 31 is melted to be in an adhesive state. The belt-like object 2A in which the adhesive is melted is pressed by being overlapped by the heating roller 31 and the second opposing roller 33, so that they are immediately heat-pressed.
In this way, the belt-like product 2A is heated before the thermocompression bonding by the heating roller 31 and the second opposing roller 33 and pre-heated so as to melt the coated adhesive. Even if it is a short time, it can connect reliably.
Further, the belt-like object 2 </ b> A extends along the outer peripheral surface of the heating roller 31 from the position pressed by the second facing roller 33 and the heating roller 31 to the position pressed by the third facing roller 34 and the heating roller 31. Since the adhesive of the two strips 2A that has been heated and pressure-bonded continues to be heated by the heating roller 31, the bonding state of the two strips 2A is maintained, and the pressure-bonded surface is applied to the pressure-bonded surface. Adhesive strength is improved by fully adapting the adhesive.
In addition, since the third opposed roller 34 sandwiches the two strips 2A with the heating roller 31 while being elastically deformed, both the strips 2A can be strongly pressed to improve the connection state.

Note that the first counter roller 32 may be configured to press the belt-like object 2 </ b> A with the heating roller 31 as long as the belt-like object 2 </ b> A can be preheated by the heating roller 31 and the second counter roller 33.
However, when the first counter roller 32 and the second counter roller 33 are integrally supported and moved simultaneously, the forward movement of the second counter roller 33 is not hindered by the first counter roller 32. In this embodiment, the first opposing roller 32 is slightly retracted and attached to the second opposing roller 33 because it is necessary to consider the attachment accuracy error.
The third counter roller 34 also has an outer peripheral surface similar to the first counter roller 32, and its material is aluminum, and the gap between the heating roller 31 and the second counter roller 33 and the heating roller 31 is wider. It is also good.
Even in this case, since the strip 2A is in surface contact with the heating roller 31 from the second counter roller 33 to the third counter roller 34, the connection state of the strip 2A connected by the second counter roller 33 is maintained. be able to.

Operation | movement of the strip | belt-shaped object connection apparatus 1 which has the above structures is demonstrated sequentially, using the figure of (a)-(e) shown in FIG.
First, FIG. 3A shows a normal supply state of the band-like object 2A. From the roll 2 in use supported by the first roll support shaft 12A located at the left end of the long hole 21, The article 2A is conveyed at a speed of 12 m / min to a packaging device (not shown) via the first guide roller 23A and the third guide roller 23C.
When the remaining amount of the strip 2A in the roll 2 of the first roll support shaft 12A is reduced to a predetermined amount, a new roll 2 is loaded on the second roll support shaft 12B at the center position. Further, the heater 31 </ b> A of the heating roller 31 is activated and heating of the heating roller 31 is started.

Next, as shown in FIG. 3 (b), the adhesive tape affixed to the new roll 2 loaded on the second roll support shaft 12B is peeled off manually or by a machine, and the end of the strip 2A is cut into the raised position. In a state where the suction portion 24b of the second holding means 13B and the cutter 28b of the second cutting means 14B are pulled down so as to be positioned below the tip of 28b, the air cylinder 27b moves the suction section 24b to the raised position. The suction part 24b is moved to the left in the figure by the slide table mechanism 26b and the air cylinder 25b, and the belt-like object 2A is sucked and held. .
When the cut strip 2A is removed, the suction portion 24b is lowered by the air cylinder 27b as shown in FIG. 3C, and the tip of the cut strip 2A held by the suction portion 24b is moved to the second opposite position. It is positioned at a connection position between the roller 33 and the heating roller 31.
During this time, the first holding means 13A and the first cutting means 14A are moved to the raised position by the air cylinder 27a.

Thus, when the tip of the new strip 2A is located at the connection position, that is, between the strip 2A in use and the heating roller 31, and the cutter 28b moves backward, as shown in FIG. 35 is operated, the heating roller 31 and the first to third opposing rollers 32 to 34 approach each other, and the new belt 2A and the belt 2A in use are heated by the heating roller 31 and the second opposing roller 33. The new band 2A is connected to the band 2A that is crimped and used.
In this state where the two strips 2A are pressure-bonded, the suction portion 24b of the second holding means 13B stops sucking the new strip 2A and is retracted by the air cylinder 25b, and the first cutting means 14A. The cutter 28a is advanced by the air cylinder 29a to cut the belt-like object 2A in use.
Thereafter, the cut strip 2A is wound up by the first roll support shaft 12A rotating counterclockwise, and the cutter 28a is retracted by the air cylinder 29a after cutting the strip 2A.

In the state of FIG. 3, when the two strips 2A are sandwiched between the heating roller 31 and the second opposing roller 33 and pressed, the feeding of the strip 2A in use is momentarily stopped. ing.
This is considered to be caused by the pressing force of the heating roller 31 and the second opposing roller 33 and the roll 2 from which the connected new belt-like object 2A is fed rotated from the stationary state.
However, even if the feeding of the strip 2A in use is stopped in this way, the dancer roller 43 of the accumulating means 16 is immediately pulled down against the urging force of the spring 44, and is being used for the downstream packaging device. The supply of the strip 2A is continued without interruption.
Further, when the dancer roller 43 is pulled down and the spring 44 is extended, the urging force of the stretched spring 44 acts on the two strips 2A pressed by the heating roller 31 and the second opposing roller 33. The rotatable heating roller 31 and the second opposing roller 33 rotate while being pressed and the feeding is resumed.
In this embodiment, the time for the heating roller 31 and the second opposing roller 33 to press the band 2A is set to about 1 second, and the band 2A is fed by about 50 to 60 mm during this time. Therefore, a new strip 2A can be thermocompression bonded to the strip 2A in use over this width.
Moreover, since the member which crimps | bonds the strip | belt-shaped object 2A is the heating roller 31 and the 2nd opposing roller 33 which can rotate freely, even if the strip | belt-shaped object 2A in use contacts and press-contacts these, it stops feeding rapidly. However, since the resumption is gradually pulled out, the fluctuation of the tension is not rapid but gentle.
Further, assuming that the feeding stop time is 1 second, when the belt-like object 2A is fed at a rate of 12 m per minute as in this embodiment, it is sufficient to have a 200 mm accumulator, and the accumulator apparatus can be extremely downsized. Can do.

When the belt-like object 2A is connected, the heating roller 31 and the first to third opposing rollers 32 to 34 are separated from each other by the air cylinders 40a and 40b, as shown in FIG.
At the same time, the first holding means 13A and the first cutting means 14A are lowered by the air cylinder 27a, and the roll 2 in use of the second roll support shaft 12B is moved to the right end of the long hole 21 by the slide plate 22. Is done.
Thereafter, when the band 2A of the roll 2 supported by the second roll support shaft 12B becomes small, a new roll 2 is loaded on the first roll support shaft 12A, and the same operation is repeated thereafter.

Thus, in the present embodiment, the feeding of the belt-like object 2A is stopped for a moment when the belt-like object 2A is sandwiched, and then immediately returns to the normal conveyance speed. The fluctuation of the acting tension can be suppressed to a low level, and wrinkles on the belt-like object 2A can be prevented.
Further, since the amount of accumulation in the accumulating means 16 can be reduced, the structure of the accumulating means 16 can be simplified and reduced in size.

In addition, although the example which used the strip | belt-shaped object 2A coated with the heat-reactive adhesive agent was shown in the present Example, the strip | belt-shaped object 2A which consists of a material which melt | dissolves itself and adheres may be sufficient.
If the belt 2A is brought into surface contact over the required range of the outer peripheral surface of the heating roller 31 when the heating roller 31 and the opposing rollers 32-34 are brought close to each other, The diameter of the roller can be set freely.
For example, the diameter of the heating roller 31 can be made smaller than the diameter of the opposing rollers 32-34, or the diameter of each of the opposing rollers 32-34 can be made different, and in the above embodiment, three opposing rollers are provided. However, it may be configured to include a plurality of second opposing rollers 33 for pressure-bonding the belt-like object 2A.
If the counter roller having at least the functions of the first and second counter rollers 32 and 33 is provided, the belt-like object 2A is preheated until the belt-like object 2A is heat-pressed by the second counter roller 33 and the heating roller 31. Therefore, the third counter roller 34 can be omitted from the above embodiment.
Furthermore, the heating roller 31 and the opposing rollers 32 to 34 may be configured to be rotationally driven. In this case, the two strips are connected without almost stopping the feeding of the strip 2A. Is possible.
