Abstract

PURPOSE:To carry an article by allowing a lifter body to ascend and descend and to effectively utilize a clamp-fixed board by integrating a clamp mechanism for serving both as a floating rotary roller and a lift mechanism into the lifter body of a carrying device which has installed in the fixed board. CONSTITUTION:A lifter body 5 is constituted so that its cross section becomes a T shape, and on the upper face of its engaging part 4, a floating rotary roller 6 is provided so that an article D can be carried. Also, a clamp mechanism C for serving as a lift mechanism L, as well is integrated at a prescribed interval in the lengthwise direction, and driven so as to ascend and descend to a carrying position where the lifter body 5 has been allowed to ascend and a clamp position where said body has been allowed to descend. On the lower face of the article D, a common plate 9 is fixed, and in the common plate 9, a T groove 10 is formed in the corresponding position of a T groove 2 in which the lifter body 5 has been installed. In case of carrying the article D onto a bolster 1 and fixing it, the article D is moved by the floating rotary roller 6 by engaging the engaging part 4 of the lifter body with the T groove 10 of the article D. Also, by allowing the lifter body 5 to descend to the clamp position by a hydraulic cylinder 20 and clamping the common plate 9 by the engaging part 4, the article D is fixed on the bolster 1.

問題もある。As described above, when the clamp device independent of the die lifter is used and the clamp device is arranged on the side of the mold, the clamp device is moved in the left-right direction every time the mold is carried in and out and the size of the mold is changed. There is a problem that the position must be changed. Further, the front and rear T-grooves or square grooves and the left-right T-grooves are required on the upper surface of the bolster. However, in a bolster without such orthogonal T-grooves or square grooves and T-grooves, the clamp device is bolted. Therefore, it becomes difficult to automate the work of moving the clamp device. There is also a problem that when a large mold is used, it becomes impossible to secure a space for disposing the clamp device on the upper surface of the bolster.
