Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adherend feeding mechanism in an automatic label applying apparatus.

[0002]

2. Description of the Related Art In an automatic labeling device, various film bags, papers, paper bags, aluminum foils, aluminum foil bags, and other items to be attached are automatically fed one by one from a stand. It has a mechanism.

In the conventional feeding mechanism for the adherends, the adherends are sent out by a suction method, or the lowest one of the ones stacked on the table is sequentially placed. It is common to pull it out and send it out.

However, in the conventional method, the suction method has a complicated mechanism and no resistance is given to the adherend to be sent out next, and the stuck objects are stacked in the method of pulling out from below. It is difficult to pull out smoothly due to the influence of weight, and it is often the case that two or more adherends are delivered in a state of overlapping during operation.Each time, the adherend to which no label is attached is returned to the stand. There was a hassle of having to do it.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a simple mechanism and is capable of reliably feeding the sheets one by one. It is intended to provide a patch feeding mechanism.

[0006]

The gist of the present invention is, therefore, that the object to be adhered is swingably supported by a mounting table and a rotary shaft that is spanned by a side frame, and is delivered to one end side. Between the suspension roll supporting rod of the delivery belt, which rotatably supports the suspension roll of the belt and at the other end of which the suspension roll of the delivery belt fixed to the rotating shaft is arranged, and the suspension roll of the delivery belt. And a delivery belt that is suspended at a predetermined distance from the tip of the mounting table with the belt sandwiched therebetween. The upper peeling roll is fixed to the rotation shaft so that it can rotate in the feeding direction of the adherend. On the other hand, the lower peeling roll is a pair of peeling rolls which are stopped or fixed to the rotating shaft passed to the side frame and rotated at an extremely low speed on the side opposite to the feeding direction of the adherend, The pair of peeling rolls are arranged in the delivery direction ahead. In the attached material feeding mechanism in an automatic labeling machine comprising a transport belt.

[0007]

Next, the operation of the present invention will be described. Of the adherends on the table, the one on the top is pulled out in the delivery direction by the delivery belt. Then, the adherend moves between the pair of peeling rolls which are arranged at a predetermined interval with the tip end of the placing table sandwiched therebetween.

When the number of the adherends sent out is one, the adherends are sent out to the label sticking mechanism by the transfer belt arranged ahead of the pair of peeling rolls.

Further, when two or more adherends that have been sent out overlap and move between the pair of peeling rolls, the pair of peeling rolls has its upper peeling roll rotated in the feeding direction. , Also, since the lower peeling roll is stopped or rotating at the extremely low speed in the opposite direction to the feeding direction, the overlapped adherends are peeled off and peeled off,
As a result, only one adherend that is in contact with the upper peeling roll is reliably delivered.

Further, since the tip side of the table is inclined at an appropriate angle according to the type, thickness, etc. of the adherend, the lower side of the adherend which is in contact with the delivery belt does not easily rise. Is becoming

Further, since a weight is attached to the suspension roll supporting rod of the delivery belt and the weight can be displaced back and forth in the same direction as the delivery belt, it is suitable for the adherends stacked on the table. It is possible to apply a load and thus prevent the adherends from overlapping and coming out.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an adherend feeding mechanism according to the present invention, FIG. 2 is a front view of the same, FIG. 3 is a central longitudinal sectional view of a main part, and FIG.

In the figure, reference numerals 1 and 1 denote side frames which are erected at appropriate intervals. Reference numeral 2 is a stand for the adherend provided between the side frames 1 and 1. Further, the table 2 has a tip portion 2a.
Is inclined at a predetermined angle.

Reference numeral 3 is a rotary shaft that is passed between the side frames 1 and 1. Reference numerals 4 and 4 denote suspension roll supporting rods for a pair of delivery belts, which are swingably supported by the rotating shaft 3. Further, the suspension roll supporting rods 4 and 4 of the delivery belt are formed by projecting an end portion on the rotary shaft 3 side upward in an L shape, and a long hole 5 is formed in the horizontal portion 4a thereof. The weight 6 is attached so that the position of the weight 6 can be shifted.

Reference numerals 7 and 7 denote delivery belt suspension rolls fixed to the rotating shaft 3 outside the delivery belt suspension roll support rods 4 and 4, and 8 and 8 denote delivery belt suspension roll support rods. 4 is a suspension roll of a delivery belt rotatably supported on the other end side of 4. Further, rubber delivery belts 9, 9 are suspended between the suspension rolls 7, 8 of these delivery belts.

Numerals 10 and 11 are a pair of peeling rolls which are arranged at a predetermined interval so as to sandwich the tip end of the mounting table 2a. In addition, the pair of peeling rolls 10,
11 is arranged between the suspension roll support rods 4 and 4 of the delivery belt. And again, the pair of peeling rolls 1
The peeling rolls 10 on the upper side of 0 and 11 are attached to the rotary shaft 3 through the one-way clutch 10a.
Therefore, the peeling roll 11 on the lower side is stopped or fixed to the rotary shaft 12 passed over the side frames 1 and 1 on the side opposite to the feeding direction of the pasted object. It is rotating at an extremely low speed.

Further, the upper peeling roll 10 is provided with a layer 10 'of urethane rubber having a hardness of 90 degrees on the outer periphery thereof, while the lower peeling roll 11 is formed of rubber at least on the outer periphery thereof. In order to prevent the peeling roll 11 from being worn, it is desirable to rotate the peeling roll 11 at an extremely low speed rather than stopping it.

Further, 13 and 13 are transfer cord belts arranged ahead of the pair of peeling rolls 10 and 11 in the sending direction. 14 and 14 are suspension rolls of the transfer cord belts 13 and 13. Further, the other 15 indicates an adherend.
