Definitions

  • Slicers having the above-mentioned characteristics are, for example, described in the document EP 3 907 051 .
  • This document describes a slicer whose support surface for the bread to be cut is inclined at a fairly large angle relative to the horizontal direction.
  • the support surface has a certain inclination so that the already cut slices of bread do not press on the uncut part of the bread, which would harm the quality of the slices formed.
  • a certain slope makes it easier to move the bread downwards during cutting without the bread encountering too much resistance from the surface during its movement.
  • the aim of the invention is to provide a less complex and as compact as possible slicer which also offers improved ergonomics.
  • the support surface is inclined at an angle ( ⁇ ) greater than 10° and less than 25°, in particular between 15° and 24°, relative to a horizontal line which extends perpendicular to the front side of the slicer.
  • said guide rail for the pusher extends laterally along at least part of the receiving compartment.
  • the slicer comprises a movable movable support for supporting and/or pushing the bread to be cut or the slices of the cut bread.
  • the slicer according to the invention comprises a bagging pallet which is provided in the loading compartment. This pallet is movable between a receiving position in which the pallet extends along the plane of the support surface and a bagging position in which at least one end of the pallet is raised relative to the plane of the support surface.
  • the bagging pallet is pivotally mounted about a horizontally extending pivot axis.
  • the slicer has a lateral guide surface adjacent to the support surface.
  • This guide surface extends substantially transversely relative to the support surface and parallel to said direction of movement in order to allow the bread to be guided during its movement between the compartments.
  • the support surface is inclined between said lateral sides relative to the horizontal so that a loaf, which is placed on the support surface, rests against said guide surface.
  • the bagging pallet has a side flange connecting to the guide surface in the pallet receiving position.
  • the invention also relates to a method for automatically slicing bread into slices which enables the bread to be packaged after being sliced with a slicer having a frame with a front side, opposite a rear side, and two lateral sides extending between the front side and the rear side.
  • This slicer comprises a loading compartment connected to a receiving compartment and the loading compartment is adjacent to said front side while the receiving compartment is near said rear side.
  • This method is characterized in that the bread and the movable pusher are moved in said direction of movement inclined at an angle ( ⁇ ) greater than 10° and less than 25°, in particular between 15° and 24°, relative to a horizontal line which extends perpendicular to the front side of the slicer.
  • the bread is received by a bagging pallet following the movement of the bread from the receiving compartment to the loading compartment in said direction of movement.
  • This pallet extends substantially in said direction of movement when receiving the bread.
  • said direction of movement of the bread is upward when the bread is moved from the loading compartment to the receiving compartment. In an alternative embodiment, the direction of movement of the bread is downward when the bread is moved from the loading compartment to the receiving compartment.
  • the invention relates, in general, to an automatic bread slicer which makes it possible to package a sliced bread in a simple manner.
  • a slicer is shown very schematically in figure 1 .
  • the slicer 1 has a rectangular base and comprises a frame with a front side 2 opposite a rear side 3 and two lateral sides 4 and 5 extending between the front side 2 and the rear side 3.
  • the sides of the frame preferably each extend approximately along a straight and vertical plane.
  • the front side 2 and the rear side 3 are, for example, perpendicular to the lateral sides 4 and 5.
  • the interior of the slicer 1 Adjacent to the front side 2, the interior of the slicer 1 comprises a loading compartment 6 which is provided for placing a loaf of bread to be cut and for recovering the bread after it has been cut into slices.
  • This loading compartment 6 is connected to a receiving compartment 7 which is provided in the slicer 1 near the rear side 3.
  • an access opening 8 is provided which gives access to the loading compartment 6.
  • this access opening is not shown, but only indicated by the reference number 8.
  • the opening access opening is accessible from said front side 2 by a user who is positioned in front of this front side 2 to place a loaf of bread to be cut in the loading compartment 2 and to retrieve the bread after it has been cut into slices.
  • This access opening 8 is therefore provided in the front side 2 and/or in the upper side of the slicer 1 opposite the loading compartment 6.
  • this access opening 8 can be closed by a cover 8a, as shown in FIG. figure 2 , when operating the slicer 1.
  • a support surface 9 for the bread extends in the two aforementioned compartments 6 and 7.
  • the support surface 9 is relatively smooth and has no roughness, so that a bread can slide easily on this surface.
  • this surface 9 can have a certain structure without the surface becoming rough and this structure hindering the movement of the bread.
  • This support surface 9 is for example made of stainless steel.
  • a slot 10 is provided in the support surface 9 to allow the passage of a cutting member along a cutting plane.
  • the cutting member is provided for cutting slices of bread and comprises, for example, a circular blade which is driven around its axis. This cutting member with the circular blade, is movable along a cutting plane through said slot 10.
  • the cutting plane preferably extends perpendicularly to the support surface 9 between said compartments 6 and 7.
  • this direction of movement 11 of the bread is substantially parallel to a vertical plane which extends transversely relative to said front side 2 and/or said rear side 3, or approximately parallel to the lateral sides 4 and 5 of the chassis of the slicer 1.
  • the slicer also comprises a movable pusher 12 which can be moved in said direction of movement 11 of the bread to move the bread between said compartments 6 and 7 through the cutting plane.
  • This pusher 12 is known to those skilled in the art and comprises, for example, retractable claws 12a.
  • a pusher with retractable claws is, for example, described in the document FROM 202011005113 .
  • This pusher 12 cooperates with a movable support 13 which is also movable in said direction of movement 11 of the bread.
  • a movable support 13 is known to those skilled in the art and makes it possible to support the bread to be cut or to support the slices which are cut from the bread.
  • the movable support 13 is driven in the direction of movement of the bread.
  • the pusher 12 and the movable support 13 may, for example, be driven by means of a toothed belt extending along and adjacent to the support surface 9, as, for example, shown in the document EP 2045053 .
  • the support surface is inclined at an angle ⁇ relative to a horizontal line which extends perpendicular to the front side 2 of the slicer 1, as shown in the figure 1 .
  • This angle ⁇ is between 10° and 25°, in particular between 15° and 24°.
  • An angle ⁇ which is between 20° and 24° seems to offer the best result with regard to the quality of cutting the bread and the ergonomics for the user.
  • the support surface 9 can also be inclined at an angle ⁇ relative to a straight line which extends transversely relative to the lateral sides 4 and 5 of the slicer 1, as shown in figure 1 .
  • This angle ⁇ is, for example, between 15° and 45°.
  • the slicer 1 has a lateral guide surface 14 which is adjacent to the support surface 9.
  • This guide surface 14 extends substantially transversely relative to the support surface 9 and parallel to said direction of movement 11 in order to allow the bread to be guided during its movement between the compartments 6 and 7.
  • FIG. 2 shows very schematically a slicer 1, according to the invention, having a loading compartment 6 and a receiving compartment 7 with a support surface 9 which is inclined at an angle ⁇ relative to the horizontal in the direction of movement of the bread 11.
  • a part of the support surface 9 constitutes a bagging pallet 15 which can be moved to a bagging position from the plane of the support surface.
  • the bagging pallet 15 can pivot about an axis 19.
  • the figure 2 shows pallet 15 with a dotted line in the bagging position
  • Slicer 1 of the figure 2 has a movable pusher 12 which can move in the direction of movement 11 and which can grip a loaf 16 to be cut by retractable claws 12a. After a loaf has been placed in the loading compartment 6, it is gripped by the retractable claws 12a of the pusher 12. Then, the loaf 16 is moved by the movement of the pusher 12 to the receiving compartment 7 through the cutting plane 17. During this movement, the pusher 12 is guided by a guide rail 17 which extends substantially parallel to the support surface 9 and thus parallel to the direction of movement 11.
  • the pusher 12 is connected by a support arm 18 to the guide rail 17 which can be moved on the rail 17 using a drive system not shown in the figures.
  • This drive system may comprise, for example, an electric motor and possibly a drive belt.
  • FIG 3 shows a very schematic section along a transverse plane relative to the direction of movement 11 of the bread 16.
  • This figure shows a lateral guide surface 14 adjacent to the support surface 9 which extends substantially transversely relative to the latter and parallel to the direction of movement 11.
  • This lateral guide surface 14 delimits the compartments 6 and 7 and makes it possible to guide the bread 16 during its movement between these compartments.
  • height of the guide rail 17, this guide surface has a slot 20 for the passage of the support arm 18 of the pusher 12.
  • the guide rail 17 for the pusher 12 preferably extends outside the compartments 6 and 7. This rail 17 extends, in particular, preferably laterally along at least part of the receiving compartment 7.
  • FIGS. 4 to 9 further show an interesting embodiment of the slicer according to the invention.
  • this slicer comprises a bagging pallet 15 which can be moved to a bagging position for packaging the sliced bread.
  • the movable support 13 is moved together with the bagging pallet 15 after the bread has been sliced.
  • the bagging pallet 15 is rotatably mounted about a fixed axis 19. This axis 19 extends into the loading compartment 6 and into the plane of the support surface 9.
  • the movable support 13 When the bagging pallet 15 has reached the packaging position, the movable support 13 is folded towards the user who is in front of the front side of the slicer and in line with the pallet 15. Thus, the user can slide a bag 21 over the assembly of the movable support 13, the pallet 15 and the bread 16 in order to recover the latter, as shown in FIG. figure 9 .
  • the bagging pallet 15 is moved from its receiving position to the bagging position by rotation about an axis 19 provided near the cutting plane 17.
  • the end of the loaf 16 which is directed towards the front side 2, or towards the user, is moved upwards when the pallet is moved to its bagging position.
  • the bagging pallet 15 may comprise, for example, oblong recesses that extend next to each other. Thus, when a packaging bag 21 is slid over the cut bread and the pallet 15, this bag 21 can be slid along the recesses next to the bread 16. Thus, the format of the bag can be chosen according to the measurements of the bread.
