DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band removing device for removing a band wound around an article.

[0002]

2. Description of the Related Art For example, during distribution, a large number of articles are stacked on a pallet for transportation, and in order to prevent the collapse of the articles, a vertical periphery from the pallet to the upper surface of the article (some articles). Band around the side).

At the time of unpacking, it is necessary to cut and remove the band.
As described in Japanese Patent Publication No. 8 (JP-A-8), there is a band removing device that automatically removes a band.

In this conventional band removing device, the band position on the side surface of the article is aligned with the processing position of the band removing device. First, the hook is advanced until it comes into contact with the side surface of the article, and the hook is moved in parallel with the side surface of the article. The band is moved laterally and hooked on the band, the hook is retracted, and the band is pulled away from the article.

[0005] Next, the guide plate is advanced until it comes into contact with the side surface of the article, and is moved laterally in parallel with the article to be inserted between the article and the band.

Next, the guide roll is advanced and pressed against the guide plate via the band, thereby clamping the band.

Next, the band is cut at a position above the guide roll by advancing the cutter.

[0008] Next, by rotating the guide roll, send cut end of the band which has been clamped to the inlet of the band recovered passage, recovering withdrawn band against the article.

Finally, the band recovered in the band recovery path is intermittently cut by the reciprocating movement of the cutter.

[0010]

In the conventional band removing device, a slide guide structure and a driving means for moving the hook in the front-rear direction and the left-right direction are required, and a guide plate is required for holding the band. In addition, a slide guide structure and a driving means for moving the guide plate in the front-rear direction and in the left-right direction are required, and the structure is complicated, and a series of band removing operations is complicated.

When a plurality of bands are looped around the side of the article, there is a problem that efficient removal of each band is not sufficiently considered. Only

Below the frame 11, a plurality of collection boxes 127 for collecting the cut band pieces are arranged.

Next, the operation of this embodiment will be described.

First, in the standby state of the band removing device, the moving body 21 moves rightward, the first moving plate 31 moves backward, the contact member 37 moves backward, and the second moving plate 41 moves backward. As a result, the hook 51 retreats (position F2 in FIG. 2), the third moving plate 61 moves rearward, the cutter 71 retreats from above the hook 51, and the holding member 67 retreats backward from the hook 51 and retreats. doing. In addition, the upper pinch roller 94 is moving upward.

Then, the article 2 transported on the transport path 1 is stopped at a predetermined position on the side of the band removing device.

After the article 2 is carried in, the first air cylinder 33 operates to move the first moving plate 31 forward, the contact member 37 contacts the side surface of the article 2, and the second air cylinder 43 When the second moving plate 41 is moved forward, the hook 51 is moved to F3 in FIG.
Forward to the position and abut the side of the article 2. In this state, as shown by a two-dot chain line in FIG. 2, the cutter 71 and the holding member 67 are retracted, and a gap is formed between the concave portion 56 of the hook 51 and the projection 70 of the holding member 67. Have been.

Next, the moving body 21 moves to the left, and the hook 51 moves.
Penetrates between the article 2 and the band 4, and the band 4
Is separated from the side surface of the article 2 and fitted into the concave portion 56 of the hook 51, and the moving body 21 stops. At this time, the band 4 fitted into the concave portion 56 is detected by an optical sensor (not shown) provided on the hook 51.

Next, the third air cylinder 63 is operated and the third air cylinder 63 is operated.
The moving plate 61 moves forward, and the protrusion 70 of the holding member 67 fits into the concave portion 56 of the hook 51 via the band 4, and after the fitting, the spring 66 is compressed to hold the band 4. The cutter 71 cuts the upper side of the holding portion of the band 4 from one side edge while the holding force is increased.

Next, the second air cylinder 43 is operated to
The moving plate 41 moves rearward, the hook 51 retreats to the position F2 in FIG. 2 while holding the band 4, and the band 4 is pulled backward from between the pinch rollers 83 and 94.

Next, the upper pinch roller 94 descends, and the band 4 is sandwiched between the upper pinch roller 94 and the lower pinch roller 83.

Next, the auxiliary air cylinder 45 is operated to activate the third air cylinder.
The moving plate 61 moves backward, and the hook 51 retreats to the position F1 in FIG. At this time, since the band 4 is pinched between the pinch rollers 83 and 94 and the pinching force between the pinch rollers 83 and 94 is larger than the pinching force between the hook 51 and the pinching member 67, the band 4 is cut. The end portion comes off from between the hook 51 and the holding member 67. At this time, an ironing action is applied to the cut end portion of the band 4, and the cut end portion is cut by a cutting means 111 described later.
Bite the cutter 112 easily. The cut end of the band 4 that has come off from between the hook 51 and the holding member 67 is located in the band collection passage 95 of the collection cylinder 96.

Next, the motor 85 is operated to operate the pinch roller 8.
3, 94 and the feed rollers 100, 101 are driven to rotate, and the cut end of the band 4 is held between the feed rollers 100, 101 through the band recovery passage 95, and the feed rollers 100, 101
, 101 and guide members 103, 104 and guide member 105
And is sent to the cutting means 111. At this time, the guide member 104 approaches the guide member 105 so as to guide the band 4 to the cutting means 111.

In the cutting means 111, the cutter 112 is rotationally driven by a motor 123, and the cutter 112 and the blade receiving member 11 are rotated.
5, the band 4 is cut into short pieces, and the cut band pieces are collected in a collection box 127 through a chute 126.

Accordingly, the band 4 wrapped around the article 2 is drawn into the band removing device and is withdrawn from the article 2 and collected.

Also, the end of the band 4 is
, 101, the air cylinder 107 is actuated and the guide member 104 is separated from the guide member 105, so that the free end of the band 4 can be easily dropped.
The end portion of the band 4 is surely cut.

When the band 4 has been removed from the article 2 and cut as described above, the band removing device returns to the standby state, and the band 4 on the left side of the article 2 to be removed next is removed. The moving body 21 sequentially moves to the position, and performs the removing operation as described above.

When the bands 4 are wrapped around the four sides of the article 2 in the vertical direction, the articles 2 are horizontally rotated by a turntable or the like to remove the bands 4, and In the case where the band 4 is also hung in the horizontal direction, the reversing mechanism may be used to tilt the article 2 sideways to remove the band 4 in the horizontal direction.

[0059]

According to the band removing device of the first aspect, a base having a guide rail parallel to the side surface of the article is provided on the side of the band removing position where the article is arranged,
To the moving body that moves along the guide rail of this base,
