This disclosure relates to a cartridge for a food processing machine, such as a for a slicing food processing machine.
Food processing machines are used to process food such as to slice, weigh, classify, and package food products. Food processing machines are sometimes used to dispose stock, such as paper or film, underneath a food product, and to subsequently slice the food product and the underlying stock. However, these food processing machines often utilize a complicated assembly of separate components to achieve this task. The separate components are typically not easily adjustable to accommodate a varied number and/or position of stock rollers unspooling the stock to meet the food processing needs.
A food processing machine, and method of its use, is needed to overcome one or more of the issues associated with one or more of the existing food processing machines.
In one embodiment, a cartridge for a food processing machine is disclosed. The cartridge includes a base member, a stock roller drag brake, a nip roller, and a chute. The stock roller drag brake is rotatably attached to the base member. The nip roller is rotatably attached to the base member. The chute is attached to the base member.
In one embodiment, a food processing machine is disclosed. The food processing machine includes a frame, a stock roller, a feed roller, and a cartridge. The stock roller is rotatably connected with the frame, and configured to unspool stock. The feed roller is rotatably connected with the frame, and configured to feed the unspooled stock. The cartridge includes a base member, a stock roller drag brake, a nip roller, and a chute. The base member is connected with the frame. The stock roller drag brake is rotatably attached to the base member, and is configured to apply a braking force to the stock roller. The nip roller rotatably is attached to the base member, and is configured to apply a nip force to the feed roller. The chute is attached to the base member, and is configured to direct the fed, unspooled stock from the feed roller along a path of the chute.
In another embodiment, a method of operating a food processing machine is disclosed. One step comprises attaching a cartridge to a frame. The cartridge includes a base member, a stock roller drag brake rotatably attached to the base member, a nip roller rotatably attached to the base member, and a chute attached to the base member. Another step comprises unspooling stock from a stock roller as the stock roller drag brake applies a braking force to the stock roller. An additional step comprises feeding the unspooled stock between the feed roller and a nip roller as the nip roller applies a nip force to the feed roller. Yet another step comprises directing the fed, unspooled stock from the feed roller along a path of the chute.
The scope of the present disclosure is defined solely by the appended claims and is not affected by the statements within this summary.
The disclosure can be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the disclosure.
As shown collectively in
The control system 22, comprising at least one processor in communication with at least one memory containing processing code, is adapted to control the entire food processing machine 10 including all of its components identified herein. As such, all movements or actions of any components of the food processing machine 10 described herein are controlled by the control system 22. The product tray lift 24 is adapted to automatically rotate around pivot point 48 in counter-clockwise and clockwise directions 50 and 52 in order to respectfully raise and lower the product tray 14. It is noted that for purposes of this disclosure the term “automatically” means that one or more motors, controlled by the control system 22, are used to achieve the movement. Initially, the food product 12 is loaded in the product tray 14 while the product tray lift 24 has the product tray 14 disposed in a horizontal position (not shown) with the gate 16 holding the food product 12 in the product tray 14. After the food product 12 is loaded in the product tray 14, the product tray lift 24 is automatically rotated in counter-clockwise direction 50 to dispose the product tray 14, the gate 16, and the food product 12 held within the product tray 14 by the gate 16 in the position of
Next, the upper infeed 26 is automatically rotated clockwise 52 and the lower infeed 28 is automatically rotated counter-clockwise 50 while the gripper device 18 is automatically moved further in direction 54 to gradually move the food product 12 into the slicing device 30. Simultaneously, the stock roller 40 is automatically rotated clockwise 52 to unspool stock 56 from the stock roller 40, and the feed roller 42 is automatically rotated counter-clockwise 50 to feed the unspooled stock 56. It is noted that the stock roller 40 and the feed roller 42 are both rotatably connected with the frame 20 of the food processing machine 10. The stock 56 may comprise a backing surface such as paper or film. The unspooled stock 56 automatically follows path 58 to advance from the stock roller 40, between the feed roller 42 and a nip roller 60 of cartridge 44, along a vacuum plate 62, through a chute 64 of the cartridge 44, through slot 66 in shear bar 68, and into a path of the slicing device 30 where it is disposed underneath and against the food product 12.
The slicing device 30 simultaneously automatically slices the food product 12 and the unspooled stock 56, disposed underneath and below the food product 12, which then together fall onto the slicing conveyor 32 which is located directly underneath the slicing device 30. At this time, the sliced food product 12 is disposed against and on top of the sliced unspooled stock 56 which is disposed against and on top of the slicing conveyor 32. The slicing conveyor 32 automatically rotates counter-clockwise 50 to move the sliced food product 12 disposed on top of the sliced unspooled stock 56 to and onto the transfer conveyor 34. The transfer conveyor 34 automatically rotates counter-clockwise to move the sliced food product 12 disposed on top of the sliced unspooled stock 56 to and onto an exposed load cell conveyor 70 of the exposed load cell device 36.
The exposed load cell 72 of the exposed load cell device 36 automatically weighs the sliced food product 12 disposed against and on top of the sliced unspooled stock 56. The exposed load cell conveyor 70 of the exposed load cell device 36 then automatically moves the weighed and sliced food product 12, disposed against and on top of the sliced unspooled stock 56, to and onto the classifier device 38. The classifier device 38 automatically classifies the weighed and sliced food product 12 by determining whether the weighed and sliced food product 12 meets an acceptable criteria in part based on the determined weight of the weighed and sliced food product 12, as determined by the exposed load cell device 36. The weighed and sliced food product 12, disposed against and on top of the sliced unspooled stock 56, which is determined by the classifier device 38 to meet the acceptable criteria is then packaged. The weighed and sliced food product 12, disposed against and on top of the sliced unspooled stock 56, which is determined by the classifier device to not meet the acceptable criteria is then discarded or used for other purposes.

The stock roller drag brake 76 is rotatably attached to the base member 74 with a pin 83. The stock roller drag brake 76 comprises a top surface 82 and opposed side surfaces 84 and 86 extending perpendicularly from the top surface 82. The stock roller 40 is disposed within and between the opposed side surfaces 84 and 86 of the stock roller 40. The opposed side surfaces 84 and 86 force the stock roller 40 to be centered relative to the base member 74 of the cartridge 44. A pneumatic cylinder 88 of the cartridge 44 is configured to rotate the stock roller drag brake 76 in clockwise direction 52 relative to the base member 74 so that the top surface 82 of the stock roller drag brake 76 applies a braking force to and against the stock roller 40 so that the stock 56 from the stock roller 40 is unspooled at a regulated rate. The pneumatic cylinder 88 is driven by a pneumatic manifold 89.
The nip roller 60 is rotatably attached to the base member 74 with a pin 90. The nip roller 60 comprises a roller 92 rotatably disposed between opposed side surfaces 94 and 96. A pneumatic cylinder 98 of the cartridge 44 is configured to rotate the nip roller 60 in counter-clockwise direction 50 relative to the base member 74 so that the roller 92 applies a nip force to the stock 56 and the feed roller 42 as the stock 56 feeds to and between the roller 92 and the feed roller 42 along the path 58. The pneumatic cylinder 98 of the cartridge 44 is also configured to rotate the nip roller 60 in clockwise direction 52 relative to the base member 74 so that the roller 92 applies less of a nip force to the stock 56 and the feed roller 42 as the stock 56 feeds to and between the roller 92 and the feed roller 42 along the path 58. The pneumatic cylinder 98 is driven by the pneumatic manifold 89. In such manner, a variable amount of nip force may be applied by the nip roller 60 to the stock 56 and the feed roller 42 as the stock 56 feeds to and between the roller 92 and the feed roller 42 along the path 58.
