Definitions

  • the invention relates to a tray sealing machine comprising a feed device with the features of claim 1.
  • Object of the present invention is to improve a feed device of a tray sealing machine to the effect that even shallow trays can be processed.
  • the tray sealing machine comprises a feed device (10) with at least two mutually parallel conveyor belts for transporting trays and is characterized in that the conveyor belts comprise a plurality of tabs on which feed webs are secured against rotation fastened.
  • the anti-rotation of the feed webs allows the use of profiled feed webs and thus a way to adapt to particularly shallow but also high shells.
  • the conveyor belts conveyor chains to provide high stability with low tolerances in the transport direction and to enable in conjunction with guide rails high lateral stability.
  • the tab is preferably a part of a chain link of the conveyor chain, which allows interchangeability of a chain link to the previously known feed devices and a space-saving design.
  • the tab is designed as a cast or turned milled part, which can be produced in one operation on a corresponding machine and replaces an existing chain link of the conveyor chain.
  • the material of the tab is stainless steel to ensure good cleanability and to meet high standards of hygiene.
  • the feed webs have at least one planar contact surface.
  • the feed webs are particularly expediently provided as square bars, since they must be processed only at the ends to be used in the tray sealing machine.
  • the material of the feed webs is stainless steel, to ensure good cleanability and to meet high standards of hygiene.
  • the feed webs are attached without tools to the tabs to facilitate replacement of the feed webs, for example, for maintenance purposes for the operator.
  • the feed webs are preferably arranged between two parallel to each other and aligned in the transport direction conveyor belts and one end of the feed webs is equipped with a spring which is stretched against the adjacent tab, that the feed webs on each two opposite tabs of the two conveyor belts by means Spring force to be kept.
  • FIG. 1 shows a schematic view of a Schalenversch doublemaschine invention 1 with a sealing station 2.
  • the sealing station 2 has a film receptacle 4 for unwinding a lid film, not shown, and a Restfolienaufwickler 6.
  • the tray sealing machine 1 has a plurality of tracks S, which can be adapted by adaptable intermediate webs 10 to different shell dimensions. Trays 11 are moved by means of a feed device 5 in a direction of production P. Push feed webs 12 whose ends are mounted on both sides of here as conveyor chains formed conveyor belts 13, the shells 11 rows in the sealing station 2 and after processing also out again or further in the production direction P.
  • the feed device 5 comprises the two conveyor chains 13 and Feed webs 12.
  • a controller 14 controls all operations of the tray sealing machine 1 and a control unit 15, an operator can make adjustments to the machine and operate them. Before the first sealing station 2 an insertion path 16 is shown.
  • FIG. 1 shows at the beginning of the transport route for the shells 11 a loading area 16.
  • the operator puts the product-filled trays 11 each in a track S, in this illustration a total of three tracks, a.
  • the intermittently operating feed system provides for row-by-row transport of adjacent trays 11 in the direction of production P.
  • the trays 11 are moved into the area of the first tray 16 and, if provided, automatically or manually filled by operators with products (not shown) ,
  • the sealing station 2 closes by an upper tool together with a lower tool cooperating in such a way that they form a chamber around the shell 11.
  • the lidding film is sealed onto the trays 11.
  • the lidding film is cut before opening the sealing station 2, so that the trays 11 can be further transported individually in rows R.
  • the trays 11 can be transferred as finished packages to an unloading device, not shown, to feed them from there to the subsequent production process such as weighing, labeling and checking.
  • Fig. 2 shows a section of the feed device 5 with two conveyor chains 13, 13a also called chains, and a plurality of feed webs 12.
  • the feed webs 12 are designed as a square profile and have on its underside 20 cylindrical cam 21. These drivers 21 allow the transport of very shallow shells 11, since the drivers 21 can dive into slots in the transport support or level.
  • Fig. 3 shows a detailed view of a chain link 22 of a conveyor chain 13, which is designed to receive a Vorschubstegs 12 as Drehfrästeil.
  • the link plate 22 is integrated as a part of a chain link 23 of the conveyor chain 13.
  • Fig. 4 shows a detailed view of a link plate 22, which has a flat surface 24 which serves as rotation of Vorschubstegs 12 on the link plate 22. Another optional recess 25, due to its different shape from the surface 24, ensures that a first end of the feed ram 12 can be attached to the link plate 22 only in a predetermined position or orientation.
  • the chain link 22a located on the chain conveyor 22a parallel to the conveyor chain 13a may be provided for receiving the second end of the Vorschubstegs 12 in a known form of a cylindrical bolt and serve by a spring in the interior of the second end of the Vorschubstegs 12 even for a clamping and thus a secure fit during operation of the Schalenverschbeckmaschine 1.
  • the spring also allows a tool-free release of a feed ridge 12 from the feed device 5, for example, to clean this, to be replaced by another feed bar 12 or to move to another link plate 22.
  • a feed device 5 is conceivable in which the conveyor chains 13, 13a have as many link plates 22, 22a in order to be able to produce different distances in the production direction between two adjacent feed webs 12 in order to be able to process different tray dimensions in the tray closing machine 1.
  • the conveyor belts may also be belts, in particular toothed belts.
  • the link plate 22 designed for preventing rotation has only one flat surface 24, but not the additional recess 25, or else that the link plate 22 has two flat surfaces 24, possibly parallel to one another, on opposite sides.
