  • the packing assist instrument can variably be adjusted its height from the surface it stands to the position of the holding frame, which position can suitably be decided according to the various conditions for the packing work including the place for setting the instrument or workers' height so that they can work in comfortable posture.
  • While said holding frame is characterized in that it is contoured such that a lower outer peripheral surface extends in parallel with the direction of extension of an axis of the holding frame, an upper outer peripheral surface extending in continuation from the lower outer peripheral surface is designed in the form of an inclined surface slantwise extending toward the axis, and the upper inner peripheral surface is designed in the form of a curved convex surface the downward direction.
  • the "curved convex surface” means such a curved convex surface that continuously extends without any inflection point.
  • the "axial direction" of the holding frame means the direction of a phantom line extending through the substantial center of the through hole of the holding frame.
  • the lower outer peripheral surface is designed in the form of a surface extending in parallel with the axial direction of the holding frame and the upper outer peripheral surface is designed in the form of an inclined surface slantwise extending toward the holding frame generally assumes such a contour that is tapered in the upward direction.
  • the film surface of the packing bag moves as follows. First, it is first raised up while sliding along the lower outer peripheral surface of the holding frame extending in continuation from the latter, and the inclined surface, then it is reversed of the upper edge of the holding frame in the downward direction and thereafter, it is lowered from the upper edge along the curved convex surface of the holding frame smoothly extending in the downward direction.
  • the film surface of the packing bag suspends in the downward direction to assume a state in substantial parallel with the axis of the holding frame, and since the lower outer peripheral surface of the holding frame extends in parallel with the axial direction, the film surface of the packing bag suspends in the substantial parallel state with the lower outer peripheral surface.
  • the inserting operation is started and the film surface is raised up, displacement of the film surface is smoothly achieved along the lower outer peripheral surface of the holding frame.
  • the film surface is inclined at an angle suitable for reversing the film surface at the upper edge of the holding frame as the film surface is raised up along the inclined surface.
  • the film surface of the packing bag is reversed in parallel with the axis, i. e., it is reversed from the state that it is vertically raised up in the upward direction to the state that it is lowered in the downward direction as it is, it is required that the film surface is turned by an angle of 180 degrees but when the film surface is raised up along the inclined surface and then it is reversed, it is only required that the film surface is turned by the remaining angle having the inclined angle of the inclined surface subtracted from 180 degrees.
  • the film surface can easily be reversed. Namely, since the film surface is ready to be reversed by raising up along the inclined surface, the reversing of the film surface at the upper edge of holding frame is performed very smoothly.
  • the holding frame is characterized in that an inner peripheral surface of the holding frame extending from the curved convex surface to the lower end of the holding frame is recessed in such a direction that an inner diameter of the holding frame is increased. Therefore, since a cavity is formed along the whole inner peripheral of the holding frame, and the packing bag with the articles inserted therein is lowered below the position of the lower edge of the curved convex surface, no restriction to the packing bag disappears, causing the packing bag to be smoothly lowered.
  • the inclined surface of the holding frame is characterized in that an inclined angle of the inclined surface relative to the axial direction of the holding frame is set to the range of 30 to 45 degrees, and the position of a boundary between the inclined surface and the lower outer peripheral surface and the position of a lower edge of the curved concave surface are located higher than about a half of the height from the lower end to the upper end of the holding frame.
  • the film surface of the packing bag is reversed downwardly from the state that the film surface is raised up as it is, it is required that the film surface is turned by an angle of 180 degrees but when the inclined angle of the inclined surface is set to the range of 30 to 45 degrees, it is only required that the inclined surface of the packing bag is turned by the remaining angle, viz, 150 to 135 degrees. Thus, the reversing of the film surface is achieved very smoothly.
  • the state of slippage and reversing of the film surface of the packing bag can be optimized.
  • the inclined angle is set to less than 30 degrees, the reversing of the film surface of the packing bag is not performed smoothly because that angle provides a weak function to the film surface of the packing bag, and in the case that it is set to more than 45 degrees, the frictional resistance appearing between the inclined surface and the film surface becomes large.
  • the slippage of the film surface is not conducted smoothly.
  • the holding frame is characterized in that each of the holding frames assumes a circular or elliptic ring-shaped contour.
  • the holding frame is designed in the circular ring-shaped contour, the articles are inserted in the state that they are collectively received in the central part of the packing bag and they are uniformly packed in the packing bag viewed from all directions.
  • a packing operation can be performed regardless of the direction of insertion of the articles.
  • the holding frame is designed in the elliptic ring-shaped contour
  • the article are not collectively received in the central part of the packing bag but are packed in the flattened state in the side-by-side relationship, and therefore they are readily recognized from the outside after they are packed in the packing bag.
  • This provides a merit that the packing bag with the articles received therein exhibits excellent aesthetic appearance when it is put on a display case or shelf.
  • a packing operation can adequately be performed depending on the kind, shape or nature of the articles.
  • each packing operation can effectively be performed.
  • the packing assist apparatus is characterized in that a guard member is disposed between the holding frame and the arm.
  • a guard member is disposed between the holding frame and the arm.
  • said holding frame is made of an expansible material so that the dimension of the through hole of said holding frame can be changed depend on the kind, shape or nature of the articles.
  • the through hole By forming the holding frame of an expansible material, the through hole, which the articles to be packed pass through, is rendered expansible so that the holding frame is adjusted to suitable dimension in accordance with the dimension of the articles to be packed.
  • Any material of any construction which can vary the size of the opening as above will do as means for making the holding frame expansible.
  • flexible metallic conduit for passing gas or steam, etc. can be used for this purpose.
  • Similar construction can be formed by utilizing reinforced plastics.
  • the holding frame there is provided with a break in part of the ring-shaped holding frame.
