Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an apparatus for peeling off a barcode label on which a barcode is printed from a separator (release paper) and attaching it to an object.

<Prior Art> Conventionally, as shown in FIG. 8, a barcode label pasting device pulls in a separator 4 to which a barcode label A on which a barcode is printed is pasted, at the terminal edge of a peeling table 19. As a result, the barcode label A is peeled off from the separator 4 and sent forward, and the label portion protruding forward from the end edge of the peeling table is attached to the suction surface S of the suction pad 5 waiting at the front part of the peeling table and the suction hole. 17, and position the front edge of the barcode label A in contact with the label stopper 18 protruding from the suction surface S. Then, the suction pad 5 holding the barcode label A by suction is moved downward. Some devices were configured to process the application by attaching the tag to the object.

<Problems to be Solved by the Invention> In the conventional structure described above, in order to prevent the tip of the barcode label A sent forward from the peeling table 19 during the label suction operation from getting caught in the tip corner 5a of the suction pad 5, It is necessary to set the suction surface S to a certain degree higher than the label feeding direction, and for this reason, when pasting the object, the suction surface S, which is set horizontally corresponding to the surface, is set to be higher than the barcode label A that is being fed out. The label suction operation was performed at a higher position.

As a result, for example, as shown in the figure, if the barcode label A is sent out from the tip of the peeling table 19 in an upward position due to a change in the peeling state, it may come off the label stopper 18 or come into contact with the label stopper 18. Even when I hit the target, it was not positioned properly and sometimes got stuck.

Therefore, as shown by the imaginary line in the figure, an air nozzle 20 is installed below the suction site to blow upward the barcode label A that has been sent forward and to ensure that it is suctioned onto the suction surface S of the suction pad 5. However, this would not only require the air nozzle 20 and its accompanying blowing means, but would also require a separate nozzle moving means for retracting the air nozzle 20 out of the downward trajectory of the suction pad 5. However, the equipment was large-scale, leading to increased costs.

In addition, there is a risk that fine dust may adhere to the bottom surface of the barcode label A, that is, the adhesive surface, and the blowing requires not only the removal of dust from the air itself, but also a means to prevent the generation of floating dust in the surrounding area. It was something.

The present invention was developed in view of the above circumstances, and it is possible to correctly position the barcode label sent out from the tip of the peeling table, hold it by suction on the suction surface of the suction pad, and transport it to the target object. The purpose of this invention is to provide a pasting device that can be used.

<Means for Solving the Problems> In order to achieve the above object, the present invention has the following configuration.

That is, the barcode label pasting device of the present invention includes a peeling table that horizontally guides and supports a separator with a barcode label pasted on its upper surface, and feeds the barcode label forward from the separator at the terminal edge by pulling the separator in and peels it off. a suction pad that is movable back and forth between the front part of the peeling table and the label pasting processing part and whose lower surface is configured as a suction surface; and a suction band that can freely move in and out of the suction surface. A barcode label pasting device equipped with a label stopper, wherein the suction pad is suspended from a support frame of a movable mechanism for band movement so as to be swingable back and forth. The suction pad is connected and supported to the lower end of the arm, and when the swinging arm swings toward the peeling table, the suction surface of the suction pad is tilted upward and approaches the terminal edge of the peeling table. .

<Function> According to the above configuration, at the barcode label peeling suction site, as shown in FIG. 7, the suction pad 5 swings toward the peeling table 19 side, and the suction surface S is tilted upward. At the same time, the tip end corner 5a of the suction pad 5 is located at a higher position than the barcode label transfer path.

Therefore, the barcode label A, which is peeled off as the separator 4 is drawn in and sent forward from the tip of the peeling table 19, is not caught by the tip parts 5a of the suction pad 5, but is kept along the suction surface S in the inclined position. advance,
The receiver is stopped and supported by the label stopper 18 and is attracted to the attraction surface S.

When the suction is completed, the suction pad 5 swings back to the right in the figure so as to separate from the peeling table 19, and after returning to a position where the suction surface S is horizontal, the predetermined pasting is moved to the treatment area.

<Embodiment> Hereinafter, an embodiment of the present invention will be explained based on the drawings. FIG. 1 shows the entire side view of a barcode label pasting device, and FIG. 5 shows the front side thereof.

As shown in FIG. 6, this barcode label attaching device is used for attaching a barcode label A for individual identification to a ring-shaped frame F that attaches and supports a semiconductor wafer W via an adhesive tape T. stand frame l
The main body case 2 is mounted and supported on an arm portion 1a extending in a cantilevered manner from the arm portion 1a so as to be adjustable in position from side to side.
The lower portion of the frame F is configured as the loading/unloading portion of the frame F, which is the object to be labeled.

Inside the main body case 2, a printing device 3 is provided which attaches barcode labels to a tape-shaped separator (release paper) at a predetermined pitch and prints a predetermined barcode label on the tape-shaped separator (release paper). After the separator 4 to which the separator is attached is horizontally transferred to the label outlet E on the front of the case, it is drawn into the case again, transferred, and then wound and collected on a reel.

In addition, on the front side of the main case 2, there is the label ejection port E.
It is equipped with a suction pad 5 that is driven up and down between the level L and the lower adhesion processing level L2, and an elevating mechanism 6 as an operating mechanism that raises and lowers the suction pad 5.

The lifting mechanism 6 includes a pair of left and right guide shafts 7 fixed to the front surface of the main body case 2, a carrier 8 that moves up and down along these, and a rodless cylinder 9 that lifts and lowers the carrier 8 by attracting it by raising and lowering an internal magnet using air. The suction pad 5 is mounted on an inverted-shaped support frame IO attached to a carrier 8.

To describe this, as shown in FIGS. 3 to 5, a swing arm 11 is suspended from the case side surface of the support frame 1O via a bracket 12 so as to be able to swing back and forth about left and right horizontal supports P. The suction pad 5 is connected and supported to the lower end of the swing arm 11 via a stay 13. Further, an air cylinder 14 is attached to the outer surface of the support frame 10, and the tip of the piston rod 14a extending from the air cylinder 14 presses a rubber contact member 15a attached to the swinging arm 11 to move the swinging arm 11 to the main body. The swing arm 11 swings until it comes into contact with a stopper 16 provided in the case 2, and when the piston rod 14a retreats, the swing arm 11 swings back to its original vertical position due to its own weight. Incidentally, a return spring may be provided at the fulcrum P of the swing arm 11 so that the swing arm 11 returns to its original position by the biasing force of the spring.

A plurality of suction holes 17 connected to a suction device (not shown) are formed on the lower surface of the suction pad 5, and the suction surface S
A pair of left and right label stoppers 18 are protruded and urged to protrude and retract. The suction pad 5 has a suction surface S that is horizontal when the swing arm 11 is in the return position shown in FIG. The tip slopes upward.

Further, as shown in FIG. 7, a plate-shaped peeling table 19 is protruded from the label outlet E of the main body case 2, and the plate-shaped peeling table 19 horizontally guides and supports the separator 4 and draws it diagonally downward and transfers it. Suction pad 5 is at label removal level L
The stopper bolt 16 is adjusted so that when the suction pad 5 is pushed out toward the main body case 2 in , the front end corner 5a of the suction pad 5 comes sufficiently close to the tip edge of the peeling table 19 and is at a position slightly higher than this. ing.

The barcode label pasting device of the present invention is constructed as described above, and its operation will be explained next.

As shown in FIG. 7, the suction pad 5 that has been raised to the label removal level L1 is attached to the main body case 2 of the swinging arm
By swinging to the side, the suction surface S approaches the tip edge of the peeling table 19 in an upwardly tilted position and stands by. As the separator 4 is pulled in, the printed barcode label A is peeled off from the tip of the peeling table 19 and sent out under the suction surface S waiting in an upwardly tilted position, and the label stopper 18 receives the printed barcode label A. It is stopped, positioned, and held by suction.

When the barcode label A is completely peeled off from the separator 4 and is attracted to the suction surface S, the swinging arm 11 is returned to the vertical position, and then the suction pad 5 is lifted up by the operation of the lifting mechanism 6. The suction pad 5 is pressed against a predetermined portion of the mount frame F set in a horizontal position at the pasting level L2, and the barcode label A on the suction surface S is pasted on the upper surface of the frame. At this time, label stopper 1
8 retracts upon contact with the upper surface of the frame.

When pasting is completed, the suction pad 5 is raised again to prepare for taking out the next barcode label A.

<Effects of the Invention> As explained above, according to the present invention, the following effects can be obtained.

(1) The downward suction surface of the suction pad is tilted upwards to receive the barcode label with respect to the tip of the peeling table, so the barcode label that is sent out will easily fit into the suction surface, and the barcode label will be slightly distorted. Even if the tip is fed out with a downward trend, it will surely contact and support the label stopper, allowing it to be picked up in a secure position.

(2) Since no means for blowing up the barcode label A toward the suction surface is required, the structure is simplified and costs can be reduced.

(3) There is no problem of fine dust adhering to the adhesive surface of the barcode label due to air blowing, and objects can be reliably adhered to the clean adhesive surface.
