Abstract
Abstract By the apparatus of the invention paper bags containing potato chips, pastries or other goods are mechanically packed into outer containers in a manner preventing the crushing or breaking of the contents of the bags and ensuring that the bags are constantly maintained in a fixed array during their passage through the apparatus. The apparatus comprises a bag conveying path, a bag lifting means cooperating with said path and having the form of parallel rows of outwardly projecting pegs moving along endless paths and adapted to receive therebetween groups of bags in a predetermined array, a horizontally and vertically movable carriage the rear portion of which lifts a group of bags from the bag lifting means onto a bag receiving platform and the front portion of which moves the group of bags along said platform, a vertically movable holder for said group of bags arranged above the platform, a means for further advancing the group of bags along the platform, and a means for transporting the group of bags onto a blank from which the outer container is subsequently formed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
187 words
An apparatus for pAckaging bags containing fragile material in a container, comprising a bag conveying path (1) for feeding the bags to a bag lifting means (3, 4) comprising parallel rows of pegs (4) which are movable along endless paths, and which extend perpendicularly of said paths, the distance between the pegs corresponding substantially to the thickness of a bag so that said bags are fixed between said pegs (4); a horizontally and vertically movable carriage (6), the rear portion of which is adapted to lift a group of bags from the bag lifting means (3, 4) onto a table (10) cooperating with a bag group holding means (11, 12) the forward portion of which carriage (6) is adapted simultaneously to move a preceding group of bags from the holder (11, 12) along the table (10); and means (13) for receiving the group of bags from the forward portion of the carriage (6) further to advance said group of bags along the table (10) up to a means (14, 15, 16) for transferring the group of bags onto a blank from which the container is subsequently formed.
Claim 2
Independent Claim
187 words
An apparatus for pAckaging bags containing fragile material in a container, comprising a bag conveying path (1) for feeding the bags to a bag lifting means (3, 4) comprising parallel rows of pegs (4) which are movable along endless paths, and which extend perpendicularly of said paths, the distance between the pegs corresponding substantially to the thickness of a bag so that said bags are fixed between said pegs (4); a horizontally and vertically movable carriage (6), the rear portion of which is adapted to lift a group of bags from the bag lifting means (3, 4) onto a table (10) cooperating with a bag group holding means (11, 12) the forward portion of which carriage (6) is adapted simultaneously to move a preceding group of bags from the holder (11, 12) along the table (10); and means (13) for receiving the group of bags from the forward portion of the carriage (6) further to advance said group of bags along the table (10) up to a means (14, 15, 16) for transferring the group of bags onto a blank from which the container is subsequently formed.
Claim 3
Dependent Claim
21 words
An arrangement according to claim 1, wherein the path (1) comprises one or more chutes in which dogs (2) are arranged.
Claim 4
Dependent Claim
51 words
An apparatus according to claim 2, wherein several chutes are arranged in side by side relationship and that the distance between the chutes decreases in the movement direction of the bags at the same time as said channels are inclined in the same direction so that the bags overlap each other.
Claim 5
Dependent Claim
51 words
An apparatus according to claim 1, wherein the carriage (6) comprises a number of parallel rods arranged straight before the interspaces between the rows of pegs on the bag lifting means, each rod being provided with two pairs of upstanding supports (7) defining forward and rear portions of the carriage (6).
Claim 6
Dependent Claim
57 words
An apparatus according to claim 4, wherein the carriage (6) is movable in a path (8) obliquely upwardly between the rows of pegs and thereafter horizontally forward so that its rear portion lifts up the group of bags from the bag lifting means to the table (10), which consists of a number of stationarily mounted horizontal rods.
Claim 7
Dependent Claim
27 words
An apparatus according to claim 5, wherein the forward portion of the carriage (6) is arranged to move the group of bags forward along the table (10).
Claim 8
Dependent Claim
40 words
An apparatus according to claim 1, wherein the bag holder (11, 12) comprises a plate, the rear and forward edge of which is provided with a pivotally suspended gate (12) for fixing the group of bags on the table (10).
Claim 9
Dependent Claim
67 words
An apparatus according to claim 1, wherein the means (13) for further advancing the group of bags along the table (10) comprises a frame, the rear and front edges of which are provided with gates, said frame being arranged to move reciprocatingly along the table (10), an inclined ridge being arranged to lift the rear gate above the group of bags upon rearward movement of said frame.
Claim 10
Dependent Claim
88 words
An apparatus according to claim 1 wherein the means (14-16) for transferring the group of bags onto the container blank is located immediately behind the table (10) and directly above a transferring plate (19) of a packaging machine, the means for transferring the group of bags comprising a horizontal plate (14) arranged for vertical reciprocating movement and which is provided with gates at its forward and rear edge for pressing the group of bags onto the container blank placed on the transferring plate (19) of the packaging machine.
Claim 11
Dependent Claim
38 words
An apparatus according to claim 1, wherein a lower plate 15 is suspended from said horizontal plate (14) in a manner such that said lower plate is freely movable up and down in relation to said horizontal plate.
Claim 12
Dependent Claim
72 words
An apparatus according to claim 1 wherein the pegs (4) of the bag lifting means are attached to chains (3) which, centrally of the path (1), extend over a wheel (5) the distance between the tops of the pegs (4) increasing and thereby enabling the bags to be fed in between the pegs, and in that the chains (3) are then horizontally arranged to fix the bags In the desired grouping array.
