When the m and 4m are moved against the bias of the springs 4k and 4k, a pair of projecting plates 4b and 4b to be retracted are mounted in the product placing plate 4a. The thrust rod 4c is
Timing at which the pair of timing belt winding mechanisms 4g, 4g is moved up and down by raising and lowering the ball nut 4f screwed into the ball screw 4e rotated by the servomotor 4d, and at the same time fixed to the elevator body. The timing belts 4h and 4h of the belt wrapping mechanisms 4g and 4g are configured to expand and contract in two stages by running. The elevator 4 is provided with a pair of overhanging plates 4 that can overhang forward and backward in the transport direction of the cardboard box H.
b and 4b are provided in the product placing plate 4a, the product placing plate 4a is detachably provided on the upper end of the push-up rod 4c, and the product placing plate 4a is a lower part on the front side in the transfer direction of the cardboard box H. It passes between the lid piece h2 and the lower lid piece h1 on the rear side and rises up to the vicinity of the upper end of the upper lid piece, and the pair of overhanging plates 4b, 4b overhang inside the box and stop. , W ・ are placed, the product placing plate 4a is lowered to accommodate the boxed items W, W ・ in the box once or several times, and when they are located at the bottom of the box, the It is configured so that the exit plates 4b, 4b are contracted and returned downward.

Next, the operation of the embodiment having the above structure will be briefly described. The cardboard box H of the cardboard box transfer means 3 is opened in a state in which the lid pieces h1 to h4 and h5 to h8 are opened in a vertically rectangular tube shape and the lower lid piece h1 on the rear side in the transfer direction is bent inward. When it is fed between the endless belts 3a, 3a, the pair of endless belts 3a, 3a of the corrugated cardboard box transfer means 3 sandwiches the corrugated cardboard box H and stops positioning at a position matching the center of the elevator 4. In this process, the pair of rails 5 and 5 respectively pass the lower lid pieces on both sides of the corrugated board box H in the transfer direction to the outside, and the inclined portions 5a bend the lower lid pieces on the front side of the corrugated board box H in the transfer direction to the inside. The lower lid piece on the rear side in the transfer direction is placed and guided. Then, the push-up rod 4c of the elevator 4 pushes up, and the product placing plate 4a passes between the lower lid piece on the front side and the lower lid piece on the rear side of the cardboard box H in the transfer direction and rises to near the upper end of the upper lid piece. Further, when the pair of overhanging plates 4b, 4b are stopped in a state of overhanging in the box and the boxed products W, W are placed, the product placing plate 4a is lowered and the boxed products W, W
When the box is housed in the box once or several times and is located at the bottom of the box, the projecting plates 4b and 4b are contracted to return to the lower position. Then, the corrugated cardboard box transfer means 3 is activated to carry out the cardboard box in the opposite direction to the retracting side, and at the same time, the corrugated cardboard box H to be fed next is sandwiched, and the corrugated cardboard box is transferred again to a position that coincides with the center of the elevator 4. . When the sizes of the corrugated cardboard boxes H are different, the pair of movable frames 2 and 2 approach each other or are separated from each other, so that the interval between the endless belts 3a and 3a of the corrugated cardboard box transfer means 3 becomes equal to the width dimension of the corrugated cardboard box H. It can be adjusted with the center as a reference, and as the lifting platform 1 moves up or down, the boxed product W,
When the distance between the drop level of W · and the height of the rails 5 and 5 is adjusted to the height of the main body of the cardboard box H plus the height of the upper lid piece, the upper end of the upper lid piece of the cardboard box H is always packed in the box. It can be adjusted so that it is slightly lower than the drop level of the products W and W, and at the same time, the rails 5 and 5 are adjusted according to the bending level of the lower lid piece of the cardboard box H.
Can be adjusted, and at the same time, the lifting stop position of the product mounting plate 4a of the elevator 4 can be adjusted so as to be slightly below the drop level of the boxed products W, W. Therefore, it has versatility that each part can be adjusted according to the size change of the cardboard box H.
