摘要：【中文】本发明提供了一种接料装置，接料装置包括阻挡部、接料部和伸缩机构，阻挡部的两侧分别为产品侧和操作侧，阻挡部用于阻挡位于产品侧的产品；接料部可移动地设置，接料部具有位于产品侧的接料位置以及位于操作侧的分离位置；接料部位于接料位置的情况下，接料部用于接收产品；接料部从接料位置移动到分离位置后，在阻挡部的阻挡下，接料部与位于接料部上的产品分离；伸缩机构的至少一部分可伸缩地设置，接料部设置在伸缩机构上，以通过伸缩机构驱动接料部移动。采用该方案，接料部在阻挡部的产品侧接住产品后，接料部移动到收回位置，由于阻挡部的阻挡，产品不会随接料部一起移动，这样产品便与接料部分离并使下落到需要的位置。 【EN】The invention provides a material receiving device which comprises a blocking part, a material receiving part and a telescopic mechanism, wherein the two sides of the blocking part are respectively a product side and an operation side, and the blocking part is used for blocking a product positioned on the product side; the material receiving part is movably arranged and is provided with a material receiving position at the product side and a separation position at the operation side; the material receiving part is used for receiving products under the condition that the material receiving part is positioned at a material receiving position; after the material receiving part moves from the material receiving position to the separating position, the material receiving part is separated from a product on the material receiving part under the blocking of the blocking part; at least one part of the telescopic mechanism is arranged in a telescopic manner, and the material receiving part is arranged on the telescopic mechanism so as to drive the material receiving part to move through the telescopic mechanism. By adopting the scheme, the material receiving part moves to the withdrawing position after the material receiving part holds the product at the product side of the blocking part, and the product can not move along with the material receiving part due to the blocking of the blocking part, so that the product is separated from the material receiving part and falls to the required position.
