The specific embodiment
Below, with reference to accompanying drawing one embodiment of the present of invention are described.
Fig. 1 has shown the Bundler of one embodiment of the invention.
In described automatic packaging machine 70, be provided with the roughly band guiding vault 74 of コ word shape on the top of wrapping machine main body 72, in described band guiding vault 74, be positioned at and be formed with a series of tape channels of circuit shape 76 on the wrapping machine main body 72.
On the one hand, left-half as shown in Figure 1 in wrapping machine main body 72 can accommodate the strap reel 78 of a large amount of band B that reeled with coming in and going out.
In the present embodiment,, should not be limited to this, also strap reel 78 can be arranged on the wrapping machine external side of main body though strap reel 78 is contained in the wrapping machine main body.
On the other hand, divide formation rear haulage case 80 at the right half part of wrapping machine main body 72 by dividing plate 75.
Described rear haulage case 80 is the devices that are used for temporarily accommodating the band B ' that retracts from band guiding vault 74 when carrying out a band.Therefore, be housed in band quantity not sufficient in the described rear haulage case 80 to be used for band next time.
As showing the shown in Figure 2 of the parts identical with Fig. 6 with identical label, in the controller portion 83 that above described rear haulage case 80, disposes, have by the strap feeding device 82 of deflector roll 90 to band guiding vault 74 band supplies, with the band retracting device 84 that retracts band from band guiding vault 74, also has the band take-up device 86 of the band tension that will retract.
That is, strap feeding device 82 is made of the positive transfer roller 92 of drive side and the touch roll 88 of slave end, and band retracting device 84 and band take-up device 86 are made of the reverse roll 94 of drive side and the touch roll 88 of slave end.
In this embodiment, described positive transfer roller 92 and reverse roll 94 constitute in the mode that can rotate with 2 grades of rotative speeds respectively.In addition, under the situation of high speed rotating torque less, and torque is bigger under situation about slowly running.
That is, under the situation that positive transfer roller 92 at high speeds rotate, can be at a gallop to band guiding vault 74 side band supplies between positive transfer roller 92 and touch roll 88, at this moment, the torque of positive transfer roller 92 is less.So this condition is suitable for supplying with the situation that remains in the band in the rear haulage case 80 (the once supply of band) shown in Figure 1 to band guiding vault 74 sides.
On the other hand, positive transfer roller 92 with situation about slowly running under, can be progressively to band guiding vault 74 side band supplies.Because the torque of positive transfer roller 92 of this moment is bigger, therefore, this condition be suitable in rear haulage case 80, not had band and from strap reel 78 directly to the situations (secondary of band is supplied with) of band guiding vault 74 side band supplies.
Below, research retracts, strains.
If touch roll 88 is pressed against on the reverse roll 94, then can carry out the tension with band of retracting of band.
At this moment, if reverse roll 94 high speed rotating then can retract band at a gallop between reverse roll 94 and touch roll 88.At this moment, because the torque of reverse roll 94 is less, therefore, this condition is suitable for retract (the once tension of band) at the band behind band guiding vault 74 side band supplies.In addition, if reverse roll 94 slowly runs, then can progressively retract band between reverse roll 94 and touch roll 88, at this moment, because the torque of reverse roll 94 is bigger, therefore, this condition is suitable for the band tension (the secondary tension of band) of band after retracting.Therefore, by this condition, can strengthen the tension band.
Below, 3 explanations drive the actuating device of positive transfer roller 92 and reverse roll 94 rotations under this condition with reference to accompanying drawing.
Fig. 3 is the view of the actuating device 100 of positive transfer roller 92 of demonstration and reverse roll 94.
Supporting the axle 9 of positive transfer roller 92 and the axle 13 of supporting reverse roll 94 is arranged in parallel.The diameter that one is fixed on the minor diameter of axle on 9 is just changeing gear 15 reverses gear 19 less than the major diameter that one is fixed on the axle 13.Described minor diameter is just changeing gear 15 and major diameter reverse gear 19 is meshing with each other.On the other hand, belt pulley 45 is arranged on the sidepiece that minor diameter is just changeing gear 15 rotationally by bearing 61.In addition, large diameter variable gear 23 is assemblied in an end of described belt pulley 45, described belt pulley 45 and large diameter variable gear 23 one is fixed together with screw.Therefore, when when the turning effort from belt 51 is passed to belt pulley 45 described belt pulley 45 being rotated, large diameter variable gear 23 can rotate simultaneously.
Described large diameter variable gear 23 meshes with the minor diameter variable gear 6 of reverse roll 94 sides.Therefore, if large diameter variable gear 23 rotates, then can make usually unitary rotation of minor diameter variable gear 6.
Sidepiece at large diameter variable gear 23 and minor diameter variable gear 6 is respectively equipped with the power-transfer clutch 17,29 that is built-in with coil.These power-transfer clutchs the 17, the 29th, axially displaceable, utilize bolt 43,47 can prevent that it from being come off by the end.
Below, the effect that is driven the Bundler of positive transfer roller 92 and reverse roll 94 by described actuating device under rated condition is described.
In Bundler 20, when carrying out band, make touch roll 88 be pressed against the side face of reverse roll 94, and separate with positive transfer roller 92 by it.Afterwards, the end of band B is through after the band guiding vault 74, stops under with the state that is admitted in the drg in the band introducer.Under this state, handle packed article.
When opening fire switch, utilize the described band retracting device in back to retract band, in actuating device shown in Figure 3, apply turning effort to belt pulley 45 by belt 51.So though large diameter variable gear 23 and minor diameter variable gear 6 rotate, owing to axle 9,13 is not applied propulsive effort, therefore, reverse roll 94 and positive transfer roller 92 do not rotate.When power-transfer clutch 29 startups were worked, the rotation of minor diameter variable gear 6 still was passed to axle 13, thereby reverse roll 94 is rotated.
That is, if belt 51 is applied power, then can exert all one's strength is passed to minor diameter variable gear 6 from major diameter variable gear 23, and this moment, rotating speed increased, so, because axle 13 high speed rotating, so also high speed rotating of reverse roll 94.So, be wound on the packed article band B and can guide vault 74 side at high speed low torques from band and retract band (the once tension of band).
Then, in Bundler, carry out the tension (the secondary tension of band) of band.
In this case, power-transfer clutch 17 startups are worked, and power-transfer clutch 29 disconnects.When power-transfer clutch 17 starts when working, the axle 9 of positive transfer roller 92 rotates, accompany therewith, axle 9 with just changeing gear 15 unitary rotation.Therefore, major diameter reverses gear 19 and rotates, and reverse roll 94 rotates.At this moment, the turning effort that belt 51 is applied is passed to and slows down when major diameter reverses gear 19 just changeing gear 15 from minor diameter.So, can obtain the turning effort of low-speed high-torque, thereby can obtain to be enough to the power that is suitable for straining.
In addition, the some long bands that are pulled in once tension and secondary tension are stored in the rear haulage case 80.
Below, the conveying of band is described.
Because the conveying of described band is normally being carried out packed article after band finishes, as band next time begin to prepare to carry out, therefore, as mentioned above, it carries out in last operation from the retracting of band, through the tension of band.
, under the situation of carrying band, on the one hand, touch roll 88 is pressed against on the positive transfer roller 92 herein, on the other hand, makes touch roll 88 leave reverse roll 94.And in rear haulage case 80, what can the more residual band that is pulled.
If power-transfer clutch 29 starts work, then can exert all one's strength is passed to minor diameter variable gear 6 from major diameter variable gear 23, and then is passed to power-transfer clutch 29, and the axle 13 of reverse roll 94 sides rotates.Thus, the reverse gear 19 with the axle 13 one rotation of reverse roll 94 also rotates.Therefore, just changeing gear 15 and rotating, positive transfer roller 92 rotates simultaneously with axle 9.
At this moment since from the power of belt 51 in transmitting the way, at first be passed to minor diameter variable gear 6 from major diameter variable gear 23, make the velocity of rotation speedup of positive transfer roller 92, and, just changeing gear 15 transmission, further speedup to minor diameter owing to reverse gear 19 from major diameter.
So, before the input velocity of rotation that is produced by belt 51 is rotated positive transfer roller 92, can obtain sizable speed and promote, thereby can carry out the once supply of band like this with the rotating speed of described speedup.Therefore, can supply with band (the once supply of band) in the rear haulage case 80 to band guiding vault 74 sides fast with described high speed low torque.
Afterwards, make power-transfer clutch 17 startup work, power-transfer clutch 29 disconnects.So the rotating speed of belt pulley 45 directly is passed to axle 9 from power-transfer clutch 17, positive transfer roller 92 still rotates with original rotating speed (low speed).Therefore, can be from the power of positive transfer roller 92 output low-speed high-torque.So, utilize described power, can carry out the secondary of band and supply with, directly band is delivered to band guiding vault 74 sides from strap reel 78.
After, band is undertaken by carrying out above-mentioned action repeatedly.
Like this, by utilizing the actuating device of present embodiment, when the tension of the supply of band or band, while can carry band to retract with 2 stages.
Above, though one embodiment of the present of invention are illustrated, the present invention should not be limited to above embodiment after all.
For example, in the above-described embodiments, though the structure of positive transfer roller 92 or reverse roll 94 with idler roller 88 as shared touch roll, touch roll separately also can be set.
In addition, not only strap reel 78 can be arranged on the inside of wrapping machine main body 72, self-evident, also it can be arranged on the outside of wrapping machine main body.
The invention effect
As mentioned above, in relating to Bundler of the present invention,, just can directly supply with the band that is wound on the strap reel, therefore, can make the wrapping machine main body comparatively compact to band guiding vault owing to need not to draw case and nip rolls.So, when reducing number of components, can effectively utilize the area of space in the wrapping machine main body.
In addition, in the present invention, when the supply of band, as when band traction case is carried band,, can carry band at a high speed carrying under the situation of band with less power.In addition, as when strap reel is directly carried band, under the situation of power that must be bigger, can progressively carry band with bigger torque.
In contrast, retracting under the situation of band, can retract band fast with less torque.And then, can in the tension of band, progressively strain with bigger torque.Therefore, need not to draw case and nip rolls and just can realize the high speed band.
