PURPOSE:To improve the efficiency of picking of an article and enable the secure picking without damaging it, by moving down parallel links at a speed variable from a high level to a low level and by moving them up at a constant speed. CONSTITUTION:Picking rollers 3 rotatable at will are coupled by support arms 2 to parallel links 1, each of which is secured at one end and movable up and down at the other, in a picking equipment. The parallel links 1 are moved down at a speed variable from a high level to a low level and are moved up at a constant speed. For that reason, the rollers 3 are rapidly moved to the top of an article 5 to be picked and are slowly brought into contact with the article. Therefore, the picking rollers 3 are moved to the article 5 in a short time and the article is prevented from being damaged by the rollers. Efficient picking is thus enabled for the individual article 5. |
