Definitions

  • the invention relates to a machine for packaging various products in a shrink film.
  • the articulated bell being most generally opaque, during the entire welding and shrinking operation, the product to be packaged is thus hidden from the view of the operator and does not allow this operation to be controlled, especially to intervene if necessary.
  • the hot air contained in this bell rises to his face, which is unpleasant.
  • it is necessary for each operation to heat the entire internal volume of the bell which therefore constitutes a significant and unnecessary expense.
  • the invention overcomes these drawbacks. It targets a packaging machine of the type in question in heat-shrinkable film which is compact, economical to build and operate, allows the product to be viewed throughout the critical shrinkage phase, allows the operator to intervene if takes place during this phase, and finally can be easily implemented even by inexperienced personnel.
  • the invention consists in using in the single workstation as a means of retraction, no longer an articulated bell but a heating gantry, also articulated, but which moreover makes it possible to sweep the entire surface of the product to wrap.
  • Figures 1 and 2 show in summary perspective view a first embodiment of a machine according to the invention shown in two successive operating phases, respectively open (Figure 1) for the introduction of the product to be packaged, then closed ( Figure 2) for the welding and shrinking operation.
  • Figure 3 is a cross-sectional view of another preferred embodiment of the invention.
  • Figure 4 is a section along the axis IV-IV '.
  • the packaging machine essentially comprises a metal frame (1), carrying at one end a fixed arm (2) intended to receive a reel (3) of a heat-shrinkable film (4), folded in a U (folded ) double thickness (5) and (6), for example polyvinyl chloride.
  • a metal frame (1) carrying at one end a fixed arm (2) intended to receive a reel (3) of a heat-shrinkable film (4), folded in a U (folded ) double thickness (5) and (6), for example polyvinyl chloride.
  • a transverse pin (7) of separation fixed on one side of the frame (1), so as to move aside in order to receive the product (8) to be packaged.
  • the upper part of the frame (1) forms a work table designated by the reference (9).
  • This work table (9) is equipped with a lateral longitudinal axis (10) oriented perpendicular to the direction of the transverse pin (7) and parallel to the edge of the table (9).
  • a hinged frame (11) is articulated whose internal face of two contiguous sides (12, 13) carries heating resistors, making it possible to weld edge to edge the two sheets (5) and (6) on either side of the object (8) placed on the table (9).
  • the folding frame (11) comprises, parallel to and opposite the axis (10), a guide rail (14) in which slides the corresponding lower end (15) of a mobile gantry ( 16).
  • the opposite end (17) of the gantry (16) slides by a sleeve (18) along the axis (10).
  • the gantry (16) has a control handle (19).
  • the mobile gantry (16) arranged parallel and above the table (9) is equipped with a blower (20), connected by a conduit (21) to a hollow arm (22) in which is arranged an electric heating resistor (23).
  • This transverse hollow arm (22) is open on the opposite face of the table (9) to thus form a ramp capable of blowing hot air downwards, as indicated by the arrows (24).
  • the frame (1) On its front part, the frame (1) also includes a control console (25).
  • the operator then lowers the frame (11) ( Figure 2). By acting on the organs of the desk (25), it activates the heating resistors (12, 13) to cause around the book the edge-to-edge welding of the sheets (5) and (6) and thus the cutting.
  • the operator acts on the handle (19) to advance the gantry (16) as indicated by the double arrow (26).
  • the mobile gantry (16) sweeps the upper space of the table (9) by blowing hot air, as indicated by the arrows (24), in the direction of the book (8) to be packaged. This causes the films welded around the book to shrink (8).
  • the machine according to the invention essentially comprises a metal grid (30) intended to form a work table for receiving the product (8) to be packed in the two thicknesses (5) and (6).
  • This grid (30) is adjustable in height relative to the mobile gantry, thanks to notches (31) provided for this purpose.
  • the mobile gantry (16) is integral with the welding frame (11).
  • This mobile retraction gantry essentially consists of a fan (20) arranged at the longitudinal axis (10) parallel to the work table (9), connected by two conduits (32, 33) to two hollow arms ( 34, 35) parallel arranged on either side of the grid (30).
  • Each of these two hollow arms (see Figure 4) (34.35) has a heating plate (36) around which the electrical resistance is wound.
  • the face of each of these arms opposite the grid (30) has a longitudinal slot (37) intended to receive a distribution and protection grid for the hot air blown by the fan (20) and as indicated by the arrows (24).
  • the fan (20) is started automatically when the welding frame (11) is closed, in particular by pressing a contact placed for this purpose on the work table (9).
  • the upper arm (35) articulated around the axis (10) comes to coincide by its conduit (33) with the fixed conduit (32) of the fixed lower arm (34).
  • the assembly of the two arms respectively fixed (34) and articulated (35) is thus secured. In this way, by sliding the handle (19) in the slide (14) of the frame (11), we move well the entire shrink assembly around the product (8) to be packaged.
  • this machine can be advantageously used for packaging various products, such as printing articles: books, magazines, albums, archives, stationery, small mechanical parts, various samples: cosmetics. , toys, food items, etc.
