Definitions

  • the present invention relates to a method for packing products in a container, especially a trough- shaped package, with the use of a packing means, by which method the products are first grouped next to the packing means which is downwardly open and has two substantially vertical spaced-apart walls.
  • the invention also relates to a device for packing products in a container, especially a trough-shaped package, said device comprising a packing means, a means for feeding previously grouped products to the packing means, and a means for moving the packing means from a product feeding position to a product depositing position just above or inside the package.
  • the packing of products in trough-shaped packages is still almost exclusively carried out manually, especially with food products, such as biscuits and hamburgers, which of course is hygienically unsuitable.
  • manual packing is time-consuming and- requires a large number of packers, thus entailing heavy expenses.
  • the production capacity that can be achieved by manual packing is simply too low.
  • the main object of the present invention is therefore to provide a method and a device for automatic packing of products in a container, especially a trough-shaped package, said method and said device having a high production capacity and low labour requirements.
  • a particular object of the invention is to provide a method and a device for packing products deep down into packing boxes, if desired in several layers.
  • a further object of the invention is that the packing should be carried out hygienically and in a manner which puts a minimum of strain on the workers.
  • the method described by way of introduction is characterised in that a cloth is stretched between the downwardly directed, free edges of the two walls so that the cloth forms a bottom for the packing means; that the grouped products are fed into the packing means and placed on the stretched cloth; that the packing means, together with the products carried therein by the cloth, is positioned above and thereafter lowered down into the package; that the cloth is loosened and completely pulled away so that the products are placed on the bottom of the package; and that the packing means is lifted out of the package and, finally, returned to the initial position for another cycle.
  • the invention provides a device of the type described by way of introduction, said device being characterised in that the packing means is down ⁇ wardly open and has two substantially vertical spaced- apart walls between which the products can be fed when the packing means is in said feeding position, a cloth being stretchable between the downwardly directed edges of the two walls so as to form a product- carrying bottom for the packing means, the cloth being adapted to be removed when the packing means is in said depositing position.
  • Fig. 1 is a schematic perspective view of a device according to a first embodiment of the invention, including a product-packing means.
  • Fig. 2 is a view similar to Fig. 1 of the device in its position for feeding previously grouped products.
  • Fig. 3 is a front view of the packing means during lowering into a trough-shaped package.
  • Fig. 4 is a view similar to Fig. 3, showing the removal of the cloth from the packing means.
  • Fig. 5 shows the withdrawal of the packing means from the package in which the products remain.

  • Figs 1-5 schematically show the packing of products in a packing box by means of a method and a device according to the first embodiment of the invention.
  • the device includes a rigid packing means 1 which is open downwardly and has two substantially vertical and parallel side walls 2, 3 spaced apart from each other. In the initial position shown in Fig. 1 , a flexible cloth 4 is wrapped round the packing means 1 , a pulling means 5 being fixed to one end of the cloth 4.
  • the device also comprises a clamping means 6 applicable against the outside of the wall 2 for clamping a portion of the cloth 4 therebetween (see Fig. 2).
  • Fig. 1 shows the device in Fig. 11 in a position just before the products are deposited in a packing box.
  • Figs 1-5 schematically show the packing of products in a packing box by means of a method and a device according to the first embodiment of the invention.
  • the device includes
  • the pulling means 5 is first passed between the wall 2 and the clamping means 6, whereupon the clamping means is applied against the wall 2.
  • the cloth 4 is stretched between the downwardly directed edges of the two walls 2, 3 and held against the wall 2 by means of the clamping means 6, while the means 5 exerts a pulling force in the direction of the arrow.
  • This is the product feeding position.
  • the products 8 which here are frozen hamburgers, are grouped in per se known manner in front of the packing means 1 to which they are fed, via guides 10, by means of a feeding means 9 which is of known con ⁇ struction and therefore not described in detail.
  • the packing means 1 and the products 8 carried therein by the cloth 4 are moved to a product delivering position just above (the dash-dot lines) or inside a container in the form of a trough-shaped package 11 shown in section.
  • the packing means 1 is set down on the bottom of the package 11, and the open bottom of the packing means 1 has a shape corresponding to that of the open top of the package 11 , the distance between the walls 2, 3 of the packing means 1 being only slightly smaller than the distance between the corresponding opposing walls of the package 11.
  • Fig. 5 shows how the packing means 1- and the associated cloth 4 are lifted out of the package 11 without dislodging the products 8 therein. Then, the packing means 1 is taken back to the product feeding position for another cycle.
  • Figs 6-9 schematically show the use of special means for passing the cloth 4 round the packing means 1.
  • one end of the cloth 4 is fixed to the pulling means 5 which, in this embodiment, is connected to the piston rod of a first, vertically positioned piston-cylinder unit 12 which is connected to and movable by means of a second, horizontally positioned piston-cylinder unit 13.

  • the means 5 is moved in a direction away from the packing means 1.
  • the two plates 16, 17 define a free space 18 and have, at each opposing longitudinal edge, a rod 19 and 20, respectively, for guiding the cloth 4 (see Fig. 12).
  • the dome-shaped packing means 1 is downwardly open and has, apart from the walls 2, 3, an upper wall 21 on which three piston-cylinder units are mounted.
  • the central piston-cylinder unit 22 imparts to the packing means 1 a reciprocating vertical motion, while the other two piston-cylinder units 23 are connected to and adapted to move a holding plate 24 which is positioned inside the packing means 1 and whose function will be explained below.
  • One side wall 3 of the packing means 1 is hingedly connected to the upper side 21 and thus can be slightly pivoted, by means not shown, in a direction away from the packing means 1. In this manner, the products 8 placed on the cloth 4 can be fed in under the side wall 3 and into the packing means 1 by the horizontal movement of the cloth 4.
  • the wall 3 is swung back to its vertical position.
  • Fig. 12 shows how the packing means 1, together with the products 8 carried therein by the cloth 4, is moved substantially vertically down into a comparatively deep packing box 25 positioned thereunder, the cloth 4 being stretched between the downwardly directed edges of the side walls 2, 3 and forming the bottom 7 of the packing means 1.

Abstract

Selon un procédé d'emballage de produits (8) dans un emballage (25) en forme d'auge, on utilise un organe d'emballage (1) ouvert par le bas et ayant deux parois essentiellement verticales (2, 3) entre lesquelles un tissu (4) est tendu de façon à former le fond (7) de l'organe d'emballage (1). On abaisse l'organe d'emballage (1) et les produits (8) qu'il contient dans l'emballage (25), on relâche le tissu (4) et on le retire complètement pour que les produits (8) soient placés au fond de l'emballage (25). Finalement, on soulève l'organe d'emballage (1) hors de l'emballage (25) et on le ramène avec le tissu (4) vers une position initiale avant de commencer un nouveau cycle de travail. Un dispositif d'emballage de produits (8) dans un emballage (25) en forme d'auge comprend, outre l'organe d'emballage (1) et le tissu (4), un organe de traction (5) qui tend et retire le tissu (4).
