Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a label peeling and conveying device that peels labels one by one from a tape to which a large number of labels are releasably attached and sequentially feeds the labels.

(Prior Art) Conventionally, a device of this kind is shown in FIG. 7 (Utility Model Publication No. 8715/1983).

The above device attaches a large number of labels to a tape T in a releasable manner, bends the tape at a steep angle and pulls it through the front end corner of a peeling table 3 provided in the tape drawer transition path, thereby removing the labels L from the tape. Peel off,
The label is transported while being temporarily adhered to the transport surface of the label transport device 2 disposed downstream of the peeling table 3 by the adhesive force of the label itself.

(Problem to be Solved) The feeding device 2 is formed by endlessly extending a plurality of narrow members 23 between the rotating bodies 21, 21, and the contact area between the conveying surface and the label is small. Adhesion between the label and the conveying surface is weak.

A press plate 20 is provided between the peeling table 3 and the feeding device 2, and this is to prevent the label L from lifting off the conveying surface, and has the effect of actively pressing the label against the conveying surface. No, presser plate 20
There is a risk that labels that have passed through will be blown away during transportation when they are hit by crosswinds.

Furthermore, since the feeding speed of the feeding device 2 is set to be the same as the running speed of the tape, when the labels L are aligned without gaps on the tape T and set on the peeling and conveying device as shown in FIG. , peeling table 3
If the labels are not transferred smoothly from one label to the other, the adhesive on the adjacent edges of adjacent labels will remain stuck to each other and must be separated by hand, resulting in extremely low work efficiency.

(Means for solving the problem) The present invention prevents the labels from flying off the conveying surface of the feeding device, allows the labels to be easily peeled off by hand from the conveying surface, and furthermore allows the edges of the labels to overlap. This paper discloses a label peeling and conveying device that prevents label peeling and conveyance from being sent out without being sent out.

The label peeling and conveying device of the present invention is equipped with a label feeding device 2 that approaches the front of a peeling table 3 and moves at a speed faster than the tape drawing speed, and a peeling table is provided above the upstream end of the feeding device 2. A pressing roller 24 that presses the label sent out from 3 onto the conveying surface of a label feeding device is provided so as to be movable in the vertical direction, and the feeding device has rotating bodies 21 and 24 disposed on the upstream and downstream sides.
22, a plurality of narrow members 23, 23 are stretched endlessly between the labels 22, and the conveying width of the label feeding device 2 is smaller than the width length in the direction orthogonal to the traveling direction of the label to be conveyed. characterized by something.

(Operations and Effects) As in the past, by bending the tape at a steep angle and pulling it through the front end corner 31 of the peeling table 3, the label L is separated from the tape T and sent downstream by the forward feeding device 2. Sent. Since the feeding speed of the feeding device is faster than the tape drawing speed, even if the labels are stuck on the tape without any gaps, on the feeding device 2, adjacent labels L are lined up with gaps between them. Multiple workers can handle labels sequentially discharged from one label peeling device, greatly improving work efficiency.

Since the transport width _a1 of the feeder 2 is smaller than the label width _a2 , the label protrudes from the transport width, and the operator can easily remove the label from the feeder by pinching the protruding edge of the label. I can do it.

Furthermore, when the label is transferred from the peeling table 3 to the feeding device 2, the label is pressed against the conveying surface of the feeding device by the weight of the pressing roller, which is arranged to be able to move up and down, and the adhesive action of the label The label reliably sticks to the conveying surface, and the label will not peel off from the conveying surface during feeding.

(Example) A label peeling and conveying device is provided with a feeding device 2 on the downstream side of a label peeling device 1.

The peeling device 1 has a tape drum 13 mounted on the upstream side between both side walls 11 and 11 of a base 10 by a drum shaft 12.

The rotation shaft 64 of the pinion gear 63 is attached to the rack surfaces 62, 62 formed on the upper edges of the slide plates 61, 61 on both side walls 11, 1 of the base 10.
1 and a handwheel 65 is connected to one end of the shaft 64.

Both slide plates 61, 61 are provided with clamping screws 66 protruding outward, and the screws are inserted into the side wall 1 of the base 10.
It is slidably passed through horizontally elongated holes 14 opened at 1 and 11, and wing nuts 67 and 67 are screwed into the penetrating ends.

A front edge 31 of the peeling table 3 where the upper surface serving as a horizontal transition path of the tape T intersects with a substantially vertical front surface is pointed diagonally forward and upward. A pressure roller 68 is disposed above the front edge 31, and shafts 69 at both ends of the roller 68 fit into vertically long holes (not shown) in both slide plates 61, 61, and the roller 68 peels off under its own weight. Press the tape on table 3.

In front of the peeling table 3, a label holder 4 is disposed close to the peeling table 3 and aligned with the height of the peeling table 3, straddling slide plates 61, 61 on both sides.

As shown in FIG. 4, the pedestal 4 is formed into a corrugated plate shape in order to reduce the contact area with the label L, and the width a ₃ of the pedestal 4 relative to the width of the label in the traveling direction is equal to the width a ₄ of the label L. shorter than

A driving roller 5 is pivotally supported below the peeling table 3, and a driven roller 50 is pivotally supported opposite to the roller 5, and the tape T pulled out from the tape drum 13 is
is passed between the driving roller 5 and the driven roller 50 through the gap between the peeling table 3 and the receiving table 4. A plurality of reversing bars 7 for reversing the tape by 90 degrees are arranged on the rear side of the base 10, and the tape passed through each bar 7 is guided to a winding drum 8.

sent to.

Since the width of the label in the traveling direction is larger than the width of the pedestal 4, when the label L is completely peeled off from the tape T, the leading end of the label L comes off the pedestal 4 and transfers to the forward feeding device 2. At this time, the label L is pressed against the conveying surfaces of the narrow members 23, 23 by the weight of the pressing roller 15, and is sent downstream while being adhered to the narrow members 23, 23.

Since the feeding speed of the feeding device is a little faster than the drawing speed of the tape T, even though the labels L were stuck on the tape T without any gaps, there were gaps between adjacent labels on the feeding device. Labels are continuously ejected in this state.

Moreover, two parallel narrow members 23 of the feeding device 2,
23 is shorter than the width perpendicular to the feeding direction of the label L, the end of the label L protrudes outside the feeding device, making it easy to pinch and take out the label, and multiple workers can hold the feeding device 2 in between. Label pasting work can be done efficiently. After the label L is peeled off, the tape T is wound onto the winding drum 8, so
There's no trouble cleaning up the tape.

Also, when a wide tape with a label L width _a3 is set in the device, loosen the clamp wing nut 67 of the forward/backward moving device 6 and move the pinion gear 63 to the handle 6.

Furthermore, if the diameter of the rotating body 21 on the upstream side of the feeding device 2 is made smaller so that it approaches the peeling table 3, and the gap between the feeding device 2 and the peeling table 3 is made as small as possible, the receiving table 4 can be moved. The label can be delivered directly from the peeling table 3 to the feeding device 2 without omitting the label.

If the voltage is changed to increase the rotation of the motor 52, the amount of labels discharged per unit time can be increased, and the gap between labels on the feeding device 2 can be widened.
