Filed: 1988-10-21
Abstract: PURPOSE:To pick up a pellet smoothly from a table even though the rear of its pellet is treated by a three dimensional process by pushing up the pointed ends of thrust-up rods which are arrayed into a line of a plurality of pins after positioning them on the bisector at the rear of the pellet. CONSTITUTION:Thrust-up rods 3 are composed of two pieces of pins 3a and 3b which are arrayed at the same levels and both of them 3a and 3b are equipped with pin-shaped sharp pointed ends. Positions of the thrust-up rods 3 to a pellet 1 are established so that the pointed ends agree with a line on the transversal (or longitudinal) bisector of the pellet 1 in a state that the pins 3a and 3b get astride a recessed part 1b; besides, the pins 3a and 3b are kept in the positions that are vertical to the pellet 1. If the thrust-up rods 3 keep on thrusting up from these positions, the pins 3a and 3b of the rods 3 make a tape 2 throw out upwards in a state that respective pointed ends come into contact with the tape 2. As a result, the tape 2 is peeled off gradually from the rear of the pellet 1 with the exception of contact parts between the pointed ends of the pins and the tape 2 with the pushing up of the thrust-up rods 3. The pellet 1 is peeled off smoothly from the table 2 without damaging a pressure sensitive part 1a on the recessed part 1b of the pellet 1.
