Definitions

  • the invention relates to a sealer for closing a container.
  • the invention further relates to a lid feed for a closer and a method for feeding a lid to a closer according to the invention.
  • the cans pass through a can seamer after being filled with the beverage or food, with the filled can bodies entering via a feed path and can lids entering via another feed path.
  • the can seamer usually has several similar stations arranged in a carousel shape, in each of which a can is closed with a can lid.
  • the can lids are guided onto the can body and held on the can body with a holding plate of a folding head. This holding also serves to fix the cans against breaking out of the circular path traversed by the cans in the can seamer due to the centrifugal force.
  • the can body with the can lid is folded at the edge over a folding roller and thus closed.
  • the can with the can lid is additionally rotated around its own axis of symmetry using the folding head.
  • the folding rollers and folding heads are arranged on a respective folding shaft.
  • a generic can seamer is in the DE 749636 and the DE4234115 A1 described.
  • the can seamer includes a clamping device for holding a can to be closed. In the operating state, the can to be closed is inserted into the clamping device and secured by it in the axial and radial directions.
  • a can lid is also centered over the can opening of the can to be closed.
  • the can has a circumferential can flange in the area of the can opening and the can lid has a circumferential one Can lid flange.
  • the can seamer additionally comprises two folding rollers, each mounted rotatably about an axis, which press the can flange and the can lid flange together by means of a substantially radially acting force, the compression being achieved by continuous rolling in the circumferential direction along the circumference of the can opening he follows.
  • the can seamer is from the GB 2098899 A known.
  • the can seamer includes a clamping device for holding the can to be closed and a folding roller. In the operating state, the can to be closed is inserted into the clamping device and secured by it in the axial and radial directions.
  • a can lid is also centered over the can opening of the can to be closed. In the area of the can opening of the can body, the can has a circumferential can flange and the can lid has a circumferential can lid flange, which are folded together.
  • the can lids are fed to the can seamer by means of a lid feed and placed on the can bodies.

  • the sealer 1000' comprises a work space 2' in which the containers can be closed with a lid 101' as well as a work space 2' surrounding housing 20'.
  • the closer 1000' includes the lid feed 1' for feeding a large number of the lids 101' in a lid stack to the working space 2'.

  • a roof of the housing 20' is only shown schematically and is usually not present in practice.
  • the work area 2' has high hygiene requirements and should be insulated as well as possible from the outside (the environment 7') or delimited from the environment 7'.
  • the work space 2 ' should be able to be cleaned as residue-free as possible during cleaning.
  • the lid feed 1 ' leads via an opening 22' in the working space 2', which is sufficiently large to also enable a format change (i.e. a change to a different, in particular larger, lid size).
  • a lid clamp 5' is actuated and all lids 101' lying between the lid clamp 5' and the working space 2' are removed.
  • the opening 22' remains to the environment 7'. There is no clear demarcation between work area 2' (which is cleaned) and environment 7'.

  • the ring nozzle 6 is a ring with several nozzles, some of which clean upwards and downwards.
  • the entire pipe 21 is cleaned by reflection and gravity.
  • Fig. 6 shows a side view of the lid feed 1 according to the invention with sensor 18.
  • lids 101 lying below the lid clamp 5 are preferably removed before cleaning. These can be removed manually in the first section 11. After cleaning, the lid stack 121 must be placed back down. Using an aid 13, the stack of lids 121 can be placed back down. If the aid 13 is located below the lid 101, the position is detected by the magnetic sensor 18 and the lid clamp 5 is set to inactive.
