Definitions

  • the invention relates to a device for cutting and portioning bread with a feed device for uncut bread, a cutting device for separating individual slices in the longitudinal direction, a portioning star, which has compartments with radial receiving surfaces and perpendicular support surfaces for portioning the individual slices, and a removal device , which is arranged downstream of the portioning star and takes over the portioned individual slices from the portioning star by means of a gripping device at a transfer station.
  • the device for slicing and portioning bread described above is not suitable for portioning and packaging sliced bread from the loaves of bread described above, because the small cross-sectional area of the loaves of bread and the resulting small contact area result in an unfavorable center of gravity of the stack, so that it becomes Tends to fall over.
  • the invention is therefore based on the object of developing the generic device for cutting and portioning bread with little design effort such that loaves of bread or bread sticks which have a comparatively flat shape can be portioned by means of it.
  • each receiving surface of the portioning star forms an angle with the vertical at the transfer station between the portioning star and the downstream discharge device.
  • the portioning star has five compartments, the receiving surfaces of which are arranged at an angular distance of 72 degrees, so that the angle between the receiving surface and the vertical at the transfer station is 18 degrees.
  • the bread slices separated in the cutting device reach the receiving surface of the compartment concerned in a manner known per se. As soon as the optically / electronically scanned number of slices is in the compartment, the portioning star is pivoted by 72 degrees into the position corresponding to the transfer station.
  • a gripping device is moved into the compartment located at the transfer station and, if necessary, penetrates the relevant walls of the compartment.
  • the gripping jaws of the gripping device are closed so that the sliced bread slices lying in the compartment are gripped.
  • the gripping device is then moved into a retracted position.
  • the stacks are captured and deposited using pneumatically controlled cylinder-piston units.
  • a catch fork can be provided which engages in the compartment through recesses formed in the receiving surface when the latter is arranged for receiving individual slices advancing from the cutting device. This catch fork then secures the respective front individual pane against tipping over. If the front single pane comes into contact with the support surface, the catch fork is withdrawn from the compartment, since the front single pane is then secured against tipping over by the support surface.
  • the gripping device can have two gripper jaws which can be moved relative to one another, one of which can be brought up to the stack of individual disks from the top by recesses formed in the support surface and the other and by means of which the stack can be gripped and removed from the compartment.
  • the gripping device is preferably arranged on a boom that can be moved in and out to remove the stack from the compartment located at the transfer station.
  • the boom in turn is seated on a rotatable disc which has a further four booms, the five booms being arranged at an angular distance of 72 degrees.
  • the gripping device After the gripping device has been moved back into the position withdrawn from the compartment, the Disc by 72 degrees so that the next gripping device is then assigned to the next compartment of the portioning star that has been brought into the transfer station and can grasp the next stack.
  • a stack fixed by the gripping device can be passed on to a packaging device by means of the openable and closable gripping device at a delivery station, this placement is preferably carried out in a horizontal position.
  • the gripping device with the stack is lowered and the gripper jaws are opened. The stack no longer held by the gripper jaws enters the corresponding compartment of the packaging device located below, in which the stack is packed in a conventional manner.
  • a feed device 1 shown in the drawing only with its cutting device-side end section transports uncut loaves or bread sticks to a cutting device 2, by means of which the uncut loaves or sticks are divided into individual slices 3.
  • a portioning star 4 is arranged downstream of the cutting device 2.
  • the portioning star 4 consists of identical individual frames which are at a distance from one another in the direction of their axis of rotation and which are non-rotatably connected to one another so that they can be rotated together about the axis of rotation.
  • the portioning star 4 or its frame parts form a receiving surface 5 and a support surface 6.
  • the receiving surface 5 of the relevant compartment 7 is arranged approximately in a horizontal plane. Since the supporting surface 6 forms a right angle with the receiving surface 5, the supporting surface is located in a vertical plane in the indicated position of the compartment 7 of the portioning star 4.
  • the sliced bread slices are moved forward by the following bread slices standing on the receiving surface 5 until the front one Disc rests with its front surface against the support surface 6.
  • the portioning star 4 is pivoted until the compartment 7 is in the transfer station 8.
  • the stack of sliced bread slices is transferred from the compartment 7 of the portioning star 4 to a removal device 9.
  • the portioning star 4 has five compartments 7, i.e. five receiving surfaces 5 and five supporting surfaces 6.
  • the angular distance between the receiving surfaces 5 is accordingly 72 degrees.
  • a compartment 7 loaded with sliced bread slices accordingly has a position at the transfer station 8 in which its receiving surface 5 encloses an angle alpha of 18 degrees with the vertical.
  • the bread slices are accordingly held by both the receiving surface 5 and the supporting surface 6 during the entire time that they are located in the compartment 7.
  • the stack of sliced bread slices cannot tip over.
  • a gripping device 10 likewise formed from interconnected individual frames, engages in the compartment 7 with gripper jaws 11, 12 and picks up the bread slice stack between its gripper jaws 11, 12.
  • the gripping device 10 is arranged at the free end of a boom 13.
  • the boom 13 can be extended in such a way that the gripping device 10 can be extended from the position on the left in the drawing to the position on the right in the drawing and vice versa.
  • the gripping device 10 is extended into the right position shown in the figure.
  • the gripper jaws 11, 12 are moved towards one another so that they clamp the bread slices 3 or the stack of the bread slices 3.
  • the individual frames of the gripping device 10 are arranged such that they are located between the individual frames of the portioning star 4. Accordingly, the gripper jaw 12 can be easily moved through the support surface 6 of the portioning star 4.
  • the gripping device is moved from the position shown on the right in the figure to the position shown on the left in the figure by retracting the boom 13.
  • the discharge device 9 has five brackets 13 which are arranged on a disk 14 at an angular distance of 72 degrees. Accordingly, the disk 14 can rotate simultaneously with the portioning star 4, with a boom 13 being assigned to a compartment 7, which is located at the transfer station 8, after each rotary movement.
  • the number of five compartments 7 of the portioning star 4 results in the illustrated exemplary embodiment, since the center of gravity of the bread slice stack, which is located within the compartment 7, at the transfer station 8 then on a vertically arranged line with the bottom edge 15 of the stack and thus the corner lies between the receiving surface 5 and the supporting surface 6. This is a tipping over of the stack safely excluded.
  • the gripping device 10 is moved out of the transfer station 8 by rotating the disk 14. Finally, the boom 13 and thus the gripping device 10 comes into a vertically downward position, in which the boom 13 passes the cut bread slices 3 at a delivery station 16 to a downstream packaging machine, from which the stack of bread slices is packaged in a conventional manner.
  • the gripping device is moved downwards by extending the boom 13 until the bread slices 3 are located on a receiving part of the packaging machine. Then the gripper jaws 11, 12 of the gripping device 10 are moved apart until the bread slices 3 are released, after which the gripping device 10 is removed from the bread slices 3 by retracting the boom 13.
