Definitions

  • the present invention refers to a method and an arrangement for automatically aligning and inserting in packages products from a conveyor belt, whereby said products are aligned in rows both longitudinally and laterally against the direction of transport in an aligner, the aligned rows of products are grouped to form packaging modules in a grouping unit, whereupon the grouped products are moved by the grouping unit to a position above the packages, where they are released so that they fall down into spaces adapted for the products in the packages.
  • the object of the present invention is to provide a method and an arrangement of the kind mentioned in the introduction and known from DE-A-3.130.103, which in relation to the abovementioned already known methods and arrangements are simple in their design and very cheap to manufacture.
  • What is essentially distinguishing for the invention is that the products are aligned in stages by a number of aligning arms in the aligner, the number of aligning arms being sufficient for the alignment in question, said arms successively align the products as they are advanced and when a row of products approaches, move from an inactive position above the conveyor belt to an active position, in which the products contact the arms and are moved both longitudinally and laterally against the direction of the belt and in which active position the arms are retained a sufficient length of time to move the entire rows of products.
  • the arrangement for aligning and grouping in accordance with the present invention forms one unit, which is a prerequisite for arranging products in modules systematically and without disturbance.
  • the products can then be moved and placed in trays or boxes, which stand ready for filling.
  • the units included in the arrangement according to the invention - aligner, grouping unit and inserter - are controlled electronically.
  • the mechanical movements are carried out pneumatically (by means of air cylinders).
  • Electrically controlled valve together with photocells and switches constitute the impulse control function in the system.
  • coconut balls 1 are fed by a conveyor belt 2, from a casting station in the direction of the arrow A, Fig. 1, towards an aligner I.
  • the aligner embraces four consecutive aligning arms 3, 4, 5 and 6 arranged laterally in relation to the feed direction.
  • the three last aligning arms are indicated by means of dash-dotted lines in Fig. 1.
  • the aligning arms 3-6 are normally in the raised position above the belt 2.
  • the distance between the underside of the arms and the belt is adapted so as to permit coconut balls to pass between.
  • a photocell 7 arranged adjacent to the belt indicates the presence of this row of coconut balls and activates an air cylinder 8, which lowers the abovementioned aligning arm 3 to an active position, in which the coconut balls 1 come into contact with the arm 3 having V-formed stop faces, Fig. 1.
  • This causes the coconut balls 1 to be moved both longitudinally and laterally (maximum 20 mm) against the direction of the belt.
  • the photocell 7 also embraces a time-delay relay which ensures that the arm 3 is retained in the active alignment position a sufficient length of time to move the entire row of coconut balls 1.
  • the air cylinder 8 then moves the arm 3 to the inactive position, whereupon the coconut balls 1 are transported to the next alignment station, embracing a photocell 9 and a second alignment arm 4, which is moved between the active and inactive positions by an air cylinder (not shown). A further alignment of the row of coconut balls is carried out in this station in the same way as that described for the first arm 3.
  • the coconut ball rows are aligned in as many stations, embracing photocells, alignment arms and air cylinders, as are required to ensure that the desired alignment, which is suitable for the subsequent grouping unit,' is obtained.
  • each row is aligned in four aligning stations.
  • the aligned rows of coconut balls 1 are then transported to grouping unit II (Figs. 3 and 4) where they are grouped to form modules to suit the packaging tray 10.
  • Grouping unit II embraces a trolley 11 arranged above the conveyor belt 2.
  • the trolley 11 consists of a rectangularframe.
  • the part of the rectangular frame which is located closest to the conveyor belt 2 is connected to an air cylinder 12.
  • the part of the rectangular frame which is located furthest away from the conveyor belt 2 is provided with rolls 13 which run between a pair of horizontal guides 14, 15.
  • the air cylinder 12 When the air cylinder 12 is actuated, the trolley 11 is made to move in a plane parallel to the conveyor belt 2 from a position above the belt to a position above the packaging tray 10 arranged after the conveyor belt 2. The purpose of this movement is indicated below.
  • the trolley 11 carries guide arms 16, 17, 18, 19 and 20 arranged laterally across the conveyor belt.
  • the coconut balls 1 are grouped to form packaging modules with the aid of these guide arms 16-20.
  • Each of the guide arms 16-20 is provided with guide devices 21 so designed that the guide devices 21 on a guide arm 16 together with the guide devices 21 on an adjacent arm 17 form a compartment for each coconut ball 1.
  • the guide arms 16-20 are moved from an inactive position above the conveyor belt 2 to an active position adjacent to the belt with the aid of air cylinders 22, 23, 24, 25 and 26. These air cylinders are arranged vertically on the trolley 11, and each guide arm 16-20 is mounted on the piston rod belonging to an associated air cylinder 22-26.
  • the number of guide arms in the grouping unit is adapted to the number of coconut balls which can be held in the packaging tray 10. In the design example. presented here, four rows of twelve coconut balls 1 are to be grouped. Consequently, five guide arms are required. Both the outer guide arms 16, 20 have guide devices21 only on the side facing in towards the grouping unit, while the intermediate guide arms 17, 18, 19 have a two- sided arrangement of guide devices 21.
  • the guide arm 16 located furthest into the unit has been moved down to its active position with the aid of the air cylinder 22.
  • the abovementioned row of coconut balls 1 is then stopped by the side arm's guide devices 21, whereupon a photocell 27 (reflecting) actuates the air cylinder 23 via a time-delay relay so that the adjacent guide arm 17 is lowered to its active position.
  • the purpose of the time-delay relay is to ensure that the entire row of coconut balls 1 is adjacent to the guide arm 16 before the adjacent arm 17 is activated.
  • each ball is now located in a compartment between the two guide arms 16, 17 at the same time as the rear of the last activated arm 17 serves as a stop for the next row of coconut balls 1.
  • a photocell 27 arranged in front of the arm senses the presence of this row of coconut balls and actuates the air cylinder 24 so that the next guide arm 18 is activated. This procedure involving actuating the air cylinders by means of photocells continues until the grouping unit has been filled with coconut balls 1.
  • the air cylinder 12 When the last guide arm 20 has been lowered to its active position, the air cylinder 12 is actuated and causes a horizontal movement of the trolley 11 from the belt conveyor 2 towards the packaging tray 10. During this movement the openings in the packaging tray 10 are covered with a covering sheet 28, which lies on a level with the upper belt parts of the conveyor 2 so that the coconut balls 1 moved'by the trolley 11 can slide on top. The movement of the trolley 11 is stopped when all the coconut balls 1 are located above an opening in the tray 10.
  • the covering sheet 28 is connected with a horizontally aligned air cylinder 29, which is actuated when the grouping unit with the grouped coconut balls 1 are located in position above the packaging tray 10. The covering sheet 28 is then pulled away so that the tray 10 is exposed, whereupon each of the coconut balls 1 falls down into a space in these trays.
  • the trolley 11 is then returned to the grouping position and the cycle is completed.
  • the handling of products in accordance with the invention can, in principle, be summarized in the following steps: alignment - collection - grouping - locking - transport - insertion.
  • the design example of the invention described above refers to handling coconut balls and similar circular products. Shapes other than circular can, of course, also be handled in accordance with the principles of the invention. The only difference is in the design of the alignment unit and a corresponding change in the grouping unit.
