A food log slicing apparatus 20 and methods associated with operating the food log slicing apparatus 20 are included in the present disclosure. The food log slicing apparatus 20 and method have benefits over prior art food log slicing apparatus. With reference to the figures, one example of the food log slicing apparatus 20 is shown. The food log slicing apparatus 20 is used to slice multiple elongated food logs 22 at the same time into slices. The multiple food logs 22 may be comprised of a wide variety of edible materials including, but not limited to meat, such as pepperoni. In some embodiments, each food log 22 is elongated with a circular cross-section, is elongated with a square cross-section, is elongated with an oval cross-section, is elongated with a rectangular cross-section, but not limited to these cross-sectional. In some examples, the food logs 22 are frozen.
The food logs 22 are positioned by the food log slicing apparatus 20 such that the foods logs 22 form a horizontal row of food logs 22 and vertical columns of foods logs 22. The food logs 22 are stacked one above the other in the columns, and in side-to-side orientation in the rows, to maximize the number of food logs 22 that can be sliced at a time. The columns of food logs 22 are separated from each other.
The food log slicing apparatus 20 includes a base 24 mounted on a horizontal ground surface 26, an input and slicing portion 28 mounted on the base 24, an output portion 30 mounted on the base 24 and downstream of the input and slicing portion 28, and a control system 32 configured to control operation of the food log slicing apparatus 20. The control system 32 may be provided on the base 24. The base 24 supports the input and slicing portion 28, the output portion 30, and the control system 32 on the ground surface 26 and includes various mechanisms and power systems for powering the food log slicing apparatus 20. The input and slicing portion 28 is configured to support and handle the multiple food logs 22, to move the multiple food logs 22, and to slice the multiple food logs 22 into slices. The slices are supported on the output portion 30 of the food log slicing apparatus 20 and are moved away from the input and slicing portion 28 by the output portion 30. The control system 32 includes all the necessary hardware and software to perform all of the operations and functions of the food log slicing apparatus 20.
With reference to
The loaf tray 36 is mounted on the base 24 by the frame 34 such that the loaf tray 36 is angled relative to a horizontal plane, for example the ground surface 26, at a predetermined angle α. In an embodiment, the angle α is 40 degrees, but other angles may be used. The loaf tray 36 includes walls 44, 46, 48 which form a plurality of separate lanes 50. The loaf tray 36 includes multiple base walls 44 separated from each other by upstanding dividing walls 46 and having upstanding end walls 48 at the outer ends of the outermost base walls 44. Each base wall 44 corresponds to a separate lane 50. As shown in the drawings, two lanes 50 are provided by the loaf tray 36. The dividing wall(s) 46 and the end walls 48 extend along substantially the entire length of the base walls 44. While two base walls 44 and one dividing wall 46 are shown in the drawings to form two lanes 50, more than two base walls 44 and one dividing wall 46 may be provided to form three or more lanes 50. Each base wall 44 has a width which is approximately equal to the width of the food log 22 being cut such that the walls forming the respective lane 50 abut against, or are in close proximity to, the sides of each food log 22 in the lane 50. In an embodiment, each base wall 44 has a length which is less than the length of the food logs 22. Since more than one food log 22 is stacked in each lane 50, the walls forming the respective lane 50 have a height which accommodates multiple food logs 22 stacked on one another, while completely separating the individual stacks of food logs 22 in the separate lanes 50.
The drive assembly 38 may take a variety of forms and moves the stacks of food logs 22 to the slicing station 42. In an embodiment, the drive assembly 38 is formed of multiple grippers 52 which attach to a rear or upstream end of each food log 22 stacked in the individual lane 50 and which are driven by known means, such as a conveyor belt, to cause the food logs 22 to slide along the respective lane 50 in the loaf tray 36. In an embodiment, the drive assembly 38 is formed of a driven continuous conveyor belt which engages and presses down onto the top food log 22 in each column, and when activated, causes all of the food logs 22 in the respective column to slide along the respective lane 50 in the loaf tray 36.
The shear bar 40 is formed of an elongated wall 54 having a plurality of separate lanes 56 which are formed by openings 58 in the wall 54 to guide and position the food logs 22 in the columns. The wall 54 has an upstream face 54a and a downstream face 54b. At least the downstream face 54b is planar. The downstream face 54b is angled relative to the base walls 44 of the loaf tray 36. In an embodiment, the downstream face 54b is angled at an angle of 90 degrees relative to the base walls 44 of the loaf tray 36. The lanes 56 in the shear bar 40 align with the lanes 50 in the loaf tray 36. In an embodiment, each opening 58 is generally U-shaped having a planar base surface 60, a corner surface 62 extending from each end of the base surface 60 and a planar side surface 64 extending upwardly from the upper ends of the respective corner surfaces 62. In an embodiment, the corner surfaces 62 are curved. The openings 58 are shaped to accommodate the shape of the stacked food logs 22 in each column. Each base surface 60 has a width which is approximately equal to the width of the food log 22 being cut. Each side surfaces 64 has a height which accommodates the multiple food logs 22 stacked on one another, while completely separating the individual stacks of food logs 22 in the separate lanes 56. The lanes 56 of the shear bar 40 align with the lanes 50 of the loaf tray 36. In an embodiment, each base surface 60 is angled relative to the horizontal plane, namely the ground surface 26, at a predetermined angle. In an embodiment, the angle at which each base surface 60 is angled is the same as the angle α. In an embodiment, the angle at which each base surface 60 is angled is 40 degrees, but other angles may be used. As shown, the shear bar 40 has two openings 58 forming two lanes 56. While two openings 58/lanes 56 are shown in the drawings, more than two openings 58/lanes 56 may be provided to correspond with the number of lanes 50 provided in the loaf tray 36.
The slicing station 42 has a blade 66 which is parallel to the planar downstream face 54b of the shear bar 40 and thus angled relative to the base walls 44 of the loaf tray 36. The blade 66 is large enough to slice all of the foods logs 22 as the blade 66 passes through the plurality of food logs 22, such that the blade 66 is designed to accommodate the height of the stacked food logs 22.
In an embodiment, the output portion 30 is formed by a plurality of stacked conveyor belts 68, 70 mounted on the base 24 and driven by driving assemblies. Each conveyor belt 68, 70 has an upstream end 68a, 70a which is proximate to, but below the blade 66 of the slicing station 42, and a downstream end 68b, 70b opposite to the upstream end 68a, 70a. Each conveyor belt 68, 70 has a width which is greater than the width of all of the lanes 56 combined in the shear bar 40. In an embodiment, two conveyor belts are provided, namely, an upper conveyor belt 68 provided above a lower conveyor belt 70. The upstream end 68a of the upper conveyor belt 68 is downstream of the upstream end 70a of the lower conveyor belt 70. If more than two conveyor belts are provided, the upstream end of upper conveyor belt is spaced downstream of the conveyor belt immediately below. The output portion 30 may additionally include a conveyor belt (not shown) downstream of the plurality of conveyor belts 68, 70 which receive the slices from the sliced food logs 22 from the conveyor belts 68, 70. With this configuration, an upper set of slices is generated by the upper row of food logs 22 being cut by the slicing station 42 and then falling onto the upper conveyor belt 68, and a lower set of slices is generated by the lower row of food logs 22 being cut by the slicing station 42 and then falling onto the lower conveyor 70. Alternatively, the upper and lower conveyor belts 68, 70 can be driven such that the slices falling onto each conveyor belt 68, 70 from the slicing station 42 form a shingle pattern wherein the slices partially overlap each other, or each slice is completely separated from the next slice.
In an embodiment, the output portion 30 is formed by a conveyor belt which is wide enough to accommodate all slices falling from the slicing station 42 onto the conveyor belt.
The food log slicing apparatus 20 permits a significant increase in slicing production at a given blade speed since multiple columns and rows of the food logs 22 are being sliced. For example, if a first row of four logs 22 of pepperoni are being sliced (such that the food logs 22 are arranged side-by-side in the loaf tray 36), and then a second row of four logs 22 of peperoni are positioned above each log of the bottom row, the food log slicing apparatus 20 can slice twice as much product at the same blade speed.
