Description

TECHNICAL FIELD The present invention relates to a binding tape supply device in a seaweed binding device.

[Prior Art] In a conventional seaweed binding device, for example, as shown in FIG. 5, a guide groove 2 is provided in a machine base 1 of the binding device, and a tape 12 is supplied from a tape cassette 11 to the guide groove 2. , A hooking device 71 for adsorbing the lower surface of the rear end portion is provided through a hole 70 formed in the bottom of the rear part of the guide groove 2, and the hooking device 71 is rotated as shown by a dotted line to remove the tape 12 from the tape 12. The rear end portion is hung around the front surface of the seaweed bundle 5 held by the contact plate 3 and the pressing plate 4.

Since this winding device 71 sucks and rotates the lower surface of the rear end portion of the tape 12 from the hole at the bottom of the guide groove 2, it is necessary to supply the tape 12 to the guide groove 2 one by one. The tape cassettes 11 that are stacked and stored are connected to the rear side of the guide groove 2, and the tapes in the cassette are sucked by the vacuum pad 72 and sequentially fed to the feed roller 73 one by one and fed to the guide groove 2. ing. (JP-A-63-232
No. 117) [Problems to be Solved by the Invention] As described above, in order to wrap the tape 12 around the front of the seaweed bundle by the wrapping device 71, the guide groove 2 having a length substantially equal to the tape length is provided.
The hole is provided in the machine base 1 and the hanging device 71 is inserted in the guide groove.
The tape cassette must be equipped with 70 and only one piece of tape must be supplied in this guide groove 2.
Since it is necessary to arrange 11 at the rear side of the guide groove, the dimension of the machine base in the tape direction becomes long, and the installation space for the binding device becomes large.

Further, when the tape 12 stacked in the tape cassette 11 is adsorbed by the vacuum pad 72, two sheets may be sucked by being overlapped due to the air permeability of the tape, and may be fed to the feed roller 73 as it is, which causes trouble in bundling. There was a drawback.

[Means for Solving the Problems] In the present invention, a hanging device for hanging the tape around the front of the seaweed bundle is provided on the machine base on the side of the guide groove, and the upper surface of the tape is attached to the tape for hanging the guide groove. The inside of the tape cassette can be inserted into the guide groove by eliminating the hole inside, and the feed roller that has contacted the tape in the tape cassette, the pressing piece that presses the tape at the rear end of the tape cassette, and the feeding roller and the pressing roller. It is equipped with a turning roller that is arranged between the pieces to shift the tape in the feeding direction.Before the tape is fed by the feeding roller, the pressing piece is separated from the tape surface, and the turning piece is turned while the pressing piece is separated from the tape. Use a roller to shift the trailing edge of the uppermost tape from the position of the pressing piece only, and after the pressing piece presses the tape end, the shifted tape is fed by the feed roller to the tip of the guide groove. It's sent to the end.

[Operation] When the tape cassette is inserted to the appropriate position in the guide groove and the tape stacked in the tape cassette is held by the feed roller, the turning roller is rotated in the tape feed direction, and the tape rolls behind the tape feed roller. The side moves while being pulled by the turning roller, but because the feed roller is not rotating, this tape bulges between the feeding roller and the turning roller to separate it from the other laminated tapes, and the rear end of the tape is located at the position of the pressing piece. Get out of. Then, the pressing piece presses the upper surface of the remaining tape, and then the feed roller is rotated, so that only the separated uppermost one tape is fed to the tip of the guide groove.

When it detects that the tape has reached the tip of the guide groove, the wrapping device provided on the side of the guide groove operates to apply a suction pad from the upper surface of the tape fed into the guide groove,
Hold the upper surface of the rear end of the tape by suction or stick it, and hang it around the front of the seaweed bundle.

The rear end of the tape wound around the front of the seaweed bundle is superposed on the front end of the tape which is sent out to the guide groove front end and pushed up from the guide groove, and is bound as in the conventional case.

When the seaweed bundle 5 is sent to and is held by the contact plate 3 and the pressing plate 4, the motor 51 is activated by detecting this and the camshaft 65 is rotated.

By the rotation of the cam shaft 65, the cam 61 is separated from the cam lever 66 and the lever 23 is pulled down by the spring 25 so that the feed roller 21 is brought into contact with the tape, as indicated by the rotation angle a in the time chart of FIG. But the cam lever
70 is pushed up by the cam 64 and levered via the connecting rod 75
Since the idle pulley 72 is separated from the belt 30 by pushing up 73, the feed roller 21 does not rotate even if the pulley 29 rotates.

Also, as the lever 23 moves, the link 82 moves to the right via the branch lever 81, so the lever 33 is pulled by the spring 34, the pin 83 moves in the long hole 84, and the turning roller.
Contact 31 on tape. At this time, the pin 83 is slightly separated from the right end of the elongated hole 84 to maintain the contact pressure of the turning roller 31. The cam 63 pushes down the cam lever 68, the rod 47 pulls the lever 44, and the pressing piece 41 is lifted up against the spring 45 via the link 43, and is separated from the tape 12.

When the cam 62 pushes down the cam lever 67 at the cam rotation angle b, the rod 39 is pulled and the pulley 36 is pulled through the lever 38.
When is rotated, the pulley 35 is turned over by the timing belt 37 and together with the one roller 31, a fixed angle, for example 90 °, in the arrow direction.

However, since the feed roller 21 does not rotate, the tape bends and bulges B between the feed roller 21 and the feed roller 21, as shown in FIG. FIG. 3 shows this state.

When the turning roller 35 rotates by a certain angle and the turning operation ends, the cam 62 is disengaged from the cam lever 67 at the rotation angle c, and the lever 38 is returned by the return spring 40.

Next, when the cam 63 is separated from the cam lever 68 at the cam rotation angle d and the pulling of the rod 47 is released, the pressing piece 41 is pressed by the spring 45 to the rear end portion of the other tape except the tape whose rear end is displaced. .

After pressing with this pressing piece 41, the cam is rotated at the rotation angle e.
When 64 disengages from cam lever 70, spring 76
73 is pulled, the idle pulley 72 is pressed against the belt 30, the feed roller 21 integrated with the pulley 26 is driven via the pulley 27 and the belt 28, and the bulge B is generated and the rear end is not pressed. The uppermost tape 12 is fed toward the tip of the guide groove 2. At this time, the other tape is pressed by the pressing piece 41 and is not sent out.

When the tape 12 is fed to the tip of the guide groove 2, the rotation angle f
The cam 64 pushes up the cam lever 70 and the idle pulley 72
Is separated from the belt 30, the rotation of the feed roller 21 is stopped, the cam 61 pushes down the cam lever 66, the lever 23 is pulled through the rod 24, and the feed roller 21 is separated from the tape surface. At the same time, the branch lever 81 moves the link 82 to the left, raises the lever 33 via the pin 83 engaged with the elongated hole 84, and separates the turning roller 31 from the tape surface.

The tape end detector 6 operates by the tip of the tape 12 fed into the guide groove 2, and the binding device operates by the output signal of the tape end detector 6.

After the tip of the uppermost tape 12 is sent to the front of the seaweed bundle, the hanging device 9 operates and the suction pad 9b sucks the upper surface of the rear end of the uppermost tape 12 in the tape cassette. 1
As indicated by the dotted line in the figure, the suction tube 9a is passed over the nori bundle 5 and rotated to the front, and the tape is hung from above the nori bundle in front of the backing plate 3, leaving the overlapping portion with the front end of the tape. Then, the binding guide 8 holds the tape, and the push-up mechanism 10 overlaps the front end of the tape pushed up from the guide groove, and the suction pad 9b is separated from the tape to return the winding device 9.

The overlapping portion of the tapes held by the bundling guide 8 has the same mechanism (not shown) as the conventional bundling device.
Do the binding work with.

As shown in FIG. 2, the wrapping device 9 has a suction pipe 9a led out from a hole 91 provided in the machine base surface on the side of the guide groove 2 and a suction pad 9b inserted in the guide groove. Since the suction tube is opposed to the upper surface of the tape 12 and the guide tube is not provided at the guide groove position, the rear end of the tape is wound around the front of the seaweed bundle without hindering the insertion of the tape cassette 11 into the guide groove 2. In this case, the suction pad 9b becomes the lower surface of the tape, but since the upper surface of the tape is pressed and held by the bundling guide 8, it does not affect the overlapping state of the tapes and does not hinder the bundling. The suction pad 9b of the hanging device is
Instead of suction by air, an adhesive pad or the like may be used.

Further, the operation mechanism of the feed roller 21, the turning roller 31, and the pressing piece 41 is not limited to the one shown in the embodiment, but can be configured in an appropriate structure such as having a driving motor for each. As for 31a, a piece having a large friction coefficient such as rubber may be simply attached to a part of the outer peripheral surface of the turning roller 31. Note that the turning roller 31 may be fed with several tapes due to the contact pressure of the turning piece if the gap between the feeding roller 21 and the feeding roller 21 is too large, and if it is too close, a fold may occur in the bulge portion, so appropriate. Giving the proper spacing and contact pressure to the tape.
