PROBLEM TO BE SOLVED: To prevent the occurrence of an operation failure of a delivery plate when moving the delivery plate and a lower perforated plate in the axial core direction of the lower perforated plate by a position change means.SOLUTION: A delivery device 50 of a granular material is configured in such a manner that, when a perforated plate 60 is rotated around an axial core and a perforated plate hole 61 of the perforated plate 60 is made to communicate with a delivery port 55a of the delivery plate 55, the granular material stored in the perforated plate hole 61 is delivered from the delivery port 55a. The perforated plate 60 is configured by including an upper perforated plate 70 having an upper perforated plate hole 71 and a lower perforated plate 80 having a lower perforated plate hole 81, the perforated plate hole 61 has the upper perforated plate hole 71 and the lower perforated plate hole 81 and is increased or decreased in the volume of the perforated plate hole 61 by moving the delivery plate 55 and the lower perforated plate 81 by a position change means 90. The position change means 90 includes a moving portion 91 movable in the axial core direction of the lower perforated plate 81 while pressing the delivery plate 55 to prevent the application of an unbalanced load to the lower perforated plate 80 by abutting on a lower face of the delivery plate 55.COPYRIGHT: (C)2013,JPO&INPIT【課題】位置変更手段によって下目皿の軸心方向に繰出板および下目皿を移動させるときの繰出板の動作不良が発生することを抑制することができる。【解決手段】目皿60が軸心を中心に回転して目皿60の目皿孔61と繰出板55の繰出口55aとが連通したときに目皿孔61に溜まった粒状物が繰出口55aから繰出されるように構成されるものであり、目皿60は上目皿孔71を有する上目皿70と下目皿孔81を有する下目皿80とを備えて構成され、目皿孔61は上目皿孔71と下目皿孔81とで構成されるとともに位置変更手段90によって繰出板55および下目皿81を移動させることにより目皿孔61の容積を増減可能に構成され、位置変更手段90は繰出板55の下面に当接して下目皿81に偏荷重がかからないように繰出板55を押圧しながら下目皿80の軸心方向に移動可能に構成される移動部91を備える、粒状物の繰出装置50とする。【選択図】図3
