As shown in FIG. 6A, the movement by the transfer member 2 a is stopped by the detection signal of the second detection means 26.
Further, the pressing member 10 in the gripping means 4 descends and comes into contact with the surface of the covering film c2 of the article b.

  Then, when the blowing means 3 is brought to the front side of the transfer of the article b by the elevating means 9, and the blowing means 3 is operated in this state, it is discharged from the blowing means 3 as shown in FIG. Since the pressure air hits the front side portion of the article b, the projecting piece c22 of the covering film c2 is pushed open outward (upward) in a curved shape by the wind pressure, and moves to the side surface portion of the pressing body 15. As shown in (b), a grip allowance by the gripping means 4 is formed on the overhanging piece c22.

  When the holding member 11 in the gripping means 4 is operated in this state, the holding body 18 in the holding member 11 rotates about the support shaft 17, and the distal end portion of the holding body 18 is the holding body 15 in the pressing member 10. 6b, the projecting piece c11 of the covering film c1 is sandwiched between the side surface of the pressing body 15 and the tip of the holding body 18. As shown in FIG.

Therefore, if the transfer member 2a in the moving means 5 and the transfer means 2 is operated in a state where the blower means 3 is lowered by the elevating means 9, the article b moves to the downstream side of the transfer member 2a and FIG. ), The gripping means 4 tilts and moves obliquely upward and rearward of the guide body 20b in a state where the gripping means 4 holds the projecting piece c22 of the covering film c2.
Therefore, the covering film c2 is easily and reliably peeled off from the surface of the article b as shown in FIG. 7A by the movement of the article b and the peeling by the gripping means 4.
Finally, as shown in FIG. 7B, the covering film c2 is peeled off from the surface of the article b, and the removal of the covering films c1 and c2 from both sides of the article b is completed.
Of course, the covering film c2 is peeled off and removed only by the movement of the gripping means 4 by the movement means 5, even if the article b is not moved by the transfer means 2.

  The coating films c1 and c2 that are no longer necessary after being removed from the article b are dropped below or to the side of the machine body 1 by the release of the gripping means 4, and are appropriately discharged by the collecting means 27 as shown in FIG. The
