  Next, the operation of the label sticking device 1 described above will be described. The operation of the label sticking apparatus 1 is such that the pass line of the sheet 101 fed from the label stocker 12 advances along the surface of the upper table 19a, the tip of the label peeling table 15, and the pass line rolls (22, 23, 24). It starts with the status set to. And the operation | work which the label 100 is peeled off from the sheet | seat 101 in order, and is sequentially affixed with respect to the workpiece member 102 is automatically performed because the label sticking apparatus 1 operate | moves based on the command signal from the control apparatus which is not shown in figure. become. In the following description, a process in which one label 100 is peeled off and attached to the work member 102 and the work member 102 is discharged will be described with reference to FIGS. 4 to 13. .

  First, in the state of FIG. 4, which is a state before the label 100 is attracted to the label attracting unit 14, the label peeling table 15 is positioned below the label attracting unit 14 and protruding forward. . At this time, the label 100 is disposed on a portion of the sheet 101 located on the surface of the peeling table 15.

  Then, from the above state, the swinging member driving portion 17d in the label sticking drive mechanism 17 is actuated to swing the swinging member 17c by a predetermined small angle, and the label adsorbing portion 14 is slightly moved together with the label support member 17a. Descent the distance. As a result, the state shown in FIG. In the state shown in FIG. 6, the label suction unit 14 further performs the label 100 suction operation. At this time, the label 100 is adsorbed while the label 100 and the sheet 101 are supported in a stable posture between the label peeling table 15 and the label adsorption unit 14.

  When the label 100 is adsorbed by the label adsorbing unit 14, the link member driving unit 16c of the forward / reverse drive mechanism 16 is then operated. As a result, as shown in FIG. 7, the link members (16a, 16b) are interlocked with the operation of the link member driving unit 16c, and the label peeling table 15 is relatively displaced horizontally to a position where it is removed from below the label suction unit 14. Then, it moves backward toward the movable housing 19 side. As a result, the pass line of the sheet 101 from the leading end of the label peeling table 15 toward the pass line roll 22 changes, and the label 100 adsorbed by the label adsorbing unit 14 is peeled from the sheet 101.

  When the label 100 is peeled off from the sheet 101, the swing member driving portion 17d in the label sticking drive mechanism 17 is operated to swing the swing member 17c by a predetermined angle, and the label 100 is moved together with the label support member 17a. The adsorbed label adsorbing part 14 descends toward the mounting table 25. As a result, the state shown in FIG. 8 is obtained. At this time, the work member 102 is already placed on the placement table 25 at a predetermined position by an operator or by a work member supply mechanism (not shown). Then, the label adsorbing portion 14 that adsorbs the label 100 with the glue surface facing downward is lowered as described above, whereby the label 100 is pressed against the work member 102 and attached.

  When the above-described operation of attaching the label 100 to the work member 102 is completed, the negative pressure state is released so that the inside of the label suction portion 14 is at atmospheric pressure. Thereby, the label adsorption | suction part 14 and the label 100 will space apart. And with the operation | movement of the label sticking drive mechanism 17 performed continuously, it drives so that the label adsorption | suction part 14 may raise. Thereby, the label adsorption | suction part 14 will be located in the position in which the sticking operation | work of the next label 100 is possible.

  When the above-described operation of attaching the label 100 is completed, the work of discharging the work member 102 to which the label 100 is attached is automatically performed. When the label 100 affixing operation is completed, as shown in FIG. 5, the front end portion of the work member 102 is disposed between the plurality of work member suction portions 26 and the mounting table 25.

  Then, from the above state, the swing shaft driving portion 27b in the work member lifting mechanism 27 is actuated so that the plurality of swing shafts 27a swings downward by a predetermined small angle, and the plurality of work member suction portions. 26 descends a short distance. As a result, the state shown in FIG. 9 is obtained, and each workpiece member suction portion 26 is located at a position where it is in close contact with the workpiece member 102. In the state shown in FIG. 9, the work member 102 is further sucked by each work member suction section 26.

  When the workpiece member 102 is suctioned by the workpiece member suction portion 26, the swing shaft driving portion 27b of the workpiece member lifting mechanism 27 is then operated. As a result, as shown in FIG. 10, the plurality of swing shafts 27a swing upward by a predetermined angle, and the swing member 27a swings along with the swing member 27 and the work member 102 attracts the end of the work member 102. The suction part 26 rises to a predetermined height. Thereby, the edge part of the workpiece member 102 is lifted to a position where it contacts the drive roll 18a.

  When the end of the work member 102 is lifted to a position where it contacts the drive roll 18a, the turning shaft drive mechanism 18d in the work member discharge mechanism 18 is then actuated to turn the turning shaft 18c upward by a predetermined angle. As a result, as shown in FIG. 11, the driven roll 18b contacts the end of the work member 102 in contact with the drive roll 18a, and the end of the work member 102 is between the drive roll 18a and the driven roll 18b. It will be pinched.

  When the work member 102 is sandwiched between the drive roll 18a and the driven roll 18b, the negative pressure state is then released so that the inside of each work member suction portion 26 is at atmospheric pressure. Thereby, as shown in FIG. 12, each work member adsorption | suction part 26 and the work member 102 will space apart.

  When the workpiece member suction portion 26 and the workpiece member 102 are separated from each other, the electric motor 18h in the workpiece member discharge mechanism 18 is operated to rotate the driving pulley 18e, the belt 18g is rotated, and the driven pulley 18f is further rotated. . Then, the driving roll 18a rotates in the counterclockwise direction in FIG. 13 together with the driven pulley 18f, and the driven roll 18b rotates in the direction opposite to the driving roll 18a (clockwise in FIG. 13) as the driving roll 18a rotates. To do. Accordingly, as shown in FIG. 13, the work member 102 sandwiched between the drive roll 18a and the driven roll 18b is discharged so as to be sent out between these rolls (18a, 18b).

  As described above, according to the label sticking device 1, the sheet 101 is sent out along the surface of the label peeling table 15 by the sheet moving mechanism 13, and the label 100 arranged on the surface of the sheet 101 is fed to the label suction unit 14. Is absorbed. Then, the label peeling table 15 is driven and moved backward by the forward / reverse drive mechanism 16, whereby the label 100 sucked by the label suction unit 14 is peeled from the sheet 101. Furthermore, the label adhering unit 14 is lowered by being driven by the label sticking drive mechanism 17, whereby the label 100 is pressed against the work member 102 and attached. Therefore, according to the label sticking device 1, the work of peeling the label 100 from the sheet 101 and sticking it to the work member 102 can be automatically performed. For this reason, the efficiency fall resulting from an operator can be eliminated and the efficiency improvement of label sticking work can be aimed at. Moreover, the dispersion | variation in the sticking position of the label 100 with respect to the workpiece member 102 can also be reduced.

  Moreover, according to the label sticking apparatus 1, when the label 100 is adsorbed by the label adsorbing unit 14, the label 100 and the sheet 101 are supported between the label adsorbing unit 14 and the label peeling table 15. That is, when the label 100 is sucked, the posture of the label 100 is stably placed between the label suction unit 14 and the label peeling table 15 together with the sheet 101 in a state where the label 100 is left on the sheet 101 without being peeled. It is supported without variation. The label peeling table 15 is driven by the forward / reverse drive mechanism 16 in a state where the label 100 is sucked in a stable posture by the label suction unit 14 without variation in the state of the label 100 suction operation by the label suction unit 14. As a result, the label peeling table 15 is displaced relative to the label suction unit 14 and the label 100 is peeled from the sheet 101. The label 100 peeled from the sheet 101 while being adsorbed by the label adsorbing unit 14 is lowered as it is together with the label adsorbing unit 14 and is quickly attached to the work member 102 at an accurate position. Therefore, the labeling operation is repeatedly and stably performed accurately and promptly.

  Therefore, according to the present embodiment, it is possible to automate the labeling work, to improve the work efficiency and reduce the variation in the labeling position with respect to the work member, and to repeat the labeling work stably and accurately. The label sticking apparatus 1 can be provided.

  Moreover, according to the label sticking apparatus 1, it forms so that the front-end | tip part of the label peeling stand 15 may extend at acute angle. For this reason, when the label peeling table 15 is driven by the forward / reverse drive mechanism 16 and moves backward, the label adsorbing unit 14 starts from the surface of the sheet 101 arranged so as to be wound around the front surface of the label peeling table 15. The label 100 adsorbed on the substrate can be peeled off very easily.

  Moreover, according to the label sticking apparatus 1, the workpiece member 102 to which the label 100 is stuck is sent between the pair of rolls (18a, 18b) and automatically discharged by the workpiece member discharge mechanism 18. Therefore, in addition to the label sticking work, it is possible to automate the work of discharging the work member 102 after the label sticking is completed. Moreover, according to the label sticking apparatus 1, since the work member discharge | emission mechanism 18 rotates the driven roll 18b with the turning operation | movement of the rotating shaft 18c, the work member 102 is easily made between the drive roll 18a and the driven roll 18b. Can be pinched.

  Moreover, according to the label sticking apparatus 1, the workpiece member adsorption | suction part 26 and the workpiece member lifting mechanism 27 are further provided, and the workpiece | work member 102 of the workpiece | work member 102 is attracted | sucked to the position which adsorb | sucks the workpiece member 102 to which the label 100 was stuck, and contacts the drive roll 18a. The end is lifted. For this reason, even if the positions of the driving roll 18a and the driven roll 18b that sandwich the workpiece member 102 are higher than the position where the label 100 is attached to the sheet 101, the driving roll 18a and the driven roll 18b are surely provided. The workpiece member 102 can be held between the two. Therefore, the degree of freedom in designing the positions of the drive roll 18a and the driven roll 18b that sandwich the work member 102 can be greatly improved, and a more efficient device layout can be easily realized.
