Abstract

An apparatus for extraction of articles frozen in moulds in a freezing machine, comprises means for insertion of retaining means in the moulds for engagement with the articles. The apparatus further comprises means for lifting the retaining means for extraction of the articles. The retaining means for each mould comprise at least two plate sections adapted for insertion in a mould along the inner surfaces of two side walls of the latter facing each other. The plate sections ensure that the subject article is firmly gripped for extraction.

Claims

1. An apparatus for extraction of articles frozen in rows of moulds in a freezing machine, said apparatus comprising means for inserting retaining means in the moulds for engagement with said articles and means for lifting said retaining means for extraction of the articles, wherein the retaining means for a row of moulds comprise two rows of plate sections designed for insertion along the inner surface of two opposing outer side walls of the moulds of the row of moulds concerned, the lower edges of the plate sections of one of said rows of plate sections including a retaining flange facing the opposing plate sections of the other of said rows of plate sections, said apparatus, moreover, comprising a chute pivotal about an axis extending in substantially parallel relationship to the longitudinal direction of said rows of plate sections in the extraction position, and being, as seen in the vertical direction, offset laterally in relation to that of the rows of plate sections provided with retaining flanges, actuating means being provided for moving said chute from a first position in which it, as seen in the vertical direction, extends laterally of the two rows of plate sections concerned and to a second position in which it extends inclined with the lower end of said chute positioned below the rows of plate sections concerned in their lifted position.

2. An apparatus as claimed in claim 1, wherein the apparatus is associated with a conveyor, one end of which is located next to the rows of plate sections concerned and at the side facing away from the chute, said one end of the conveyor being at the same time proximate the lower end of the chute in said second position of the latter.

3. An apparatus as claimed in claim 1, wherein means are provided for moving the two rows of plate sections concerned away from each other after extraction of the articles supported by said plate sections.

4. An apparatus for extraction of articles frozen in rows of moulds in a freezing machine, said apparatus comprising means for inserting retaining means in the moulds for engagement with said articles and means for lifting said retaining means for extraction of the articles, wherein the retaining means for a row of moulds comprise two rows of plate sections designed for insertion along the inner surfaces of two oppositing outer side walls of the moulds of the row of moulds concerned, the lower edges of the plate sections of one of said rows of plate sections including a retaining flange facing the opposing plate sections of the other of said rows of plate sections, said apparatus, moreover, comprising a chute pivotal about an axis extending in substantially parallel relationship to the longitudinal direction of said rows of plate sections in the extraction position and being, as seen in the vertical direction, offset laterally in relation to that of the rows of plate sections provided with retaining flanges, actuating means being provided for moving said chute from a first position in which it, as seen in the vertical direction, extends laterally of the two rows of plate sections concerned and to a second position in which it extends inclined with the lower end of said chute positioned below the rows of plate sections concerned in their lifted position and wherein the upper ends of the plate sections of each of said rows of plate sections are secured to a bar, both ends of said bars being provided with means for engagement with guide means provided in said apparatus, said guide means being adapted for guiding said bars so that they are first travelling in parallel relationship and then separated from each other.

5. An apparatus as claimed in claim 4, wherein said actuating means for moving said chute is synchronized with the vertical movement of said bars to the effect that the chute is moved to said second position during the end phase of the upward movement of said bars.
