Definitions

  • the invention relates to a magazine for feeding carton blanks to a packaging machine.
  • the packaging machine is arranged to receive the carton blanks from the magazine, form packages from the carton blanks, and fill food product in packages.
  • patent document DE102013101808B4 which falls within the purview of the prior art and exemplifies some of the existing techniques for feeding carton blanks to a packaging machine. While this document presents a magazine capable of effectively feeding carton blanks, it underscores the need for more robust techniques to accurately determine and control the feed pressure exerted on the blanks. For instance, the sensor used for adapting the pressure by which the carton blanks are fed to the packaging machine appears to be sensitive to disturbances.
  • One such object is to provide for reliably feeding blanks to a packaging machine, while still ensuring efficient operation of the magazine, including convenient filling of blanks in the magazine.
  • a first aspect relates to a magazine for feeding carton blanks to a packaging machine.
  • the magazine comprises a guide unit arranged to hold a stack of carton blanks; a feed end located at an end of the guide unit, for allowing carton blanks to be picked from the magazine at the feed end; a follower that is movable along the guide unit, for allowing carton blanks to be pushed towards the feed end when the stack of carton blanks is positioned between the feed end and the follower; a drive unit to which the follower is connected, the drive unit being controllable to impart a movement to the follower in a direction towards the feed end, such that the follower applies a force on the stack of carton blanks; and a sensor device arranged to generate a signal indicative of the distance between the follower and the feed.
  • the follower is arranged to be set in one of a feeding position and a loading position, and the sensor device is arranged to generate a signal for detecting whether the follower is set in the feeding position or the loading position.
  • the magazine further comprises a processing unit operatively connected to the sensor device, and configured to control the drive unit to impart said movement to the follower when the follower is in the feeding position, and inactivate said movement of the follower when the follower is in the loading position.
  • the term “sensor device” refers to one or more sensor, which may include a processing unit, such as a microcontroller, for converting a signal generated by the sensor device to a value or signal format that represents the value or measurement the sensor has measured (sensed).
  • a processing unit such as a microcontroller
  • the feeding position respectively the loading position refers to operational positions, also referred to as operational settings, of the follower.
  • the processing unit operatively connected to the sensor device for receiving the signals from the sensor unit.
  • the processing unit can therefore, for example, perform calculations and control various operations that use the setting of the follower as input.
  • the magazine is advantageous in that it provides a secure way for determining when carton blanks shall be pushed towards the feed end. This provides, in turn, for convenient reloading of new blanks into the magazine. Moreover, the magazine also offers a convenient possibility to implement adjustment of the pressure by which the carton blanks shall be pushed with towards the feed end.
  • the follower is pivotably and/or linearly movable relative to the guide unit, between the feeding position and the loading position. This facilitates cooperation between the follower, the sensor device and the processing unit.
  • the follower may be pivotably and/or linearly movable as seen in relation to the guide unit.
  • the pivoting movement may be a pivoting movement about the longitudinal axis of the guide unit.
  • the linear movement may be a movement, or may comprise a linear movement component, that is transverse the longitudinal axis of the guide unit.
  • the follower is pivotably and/or linearly movable relative to the drive unit, between the feeding position and the loading position. This has the positive effect that the drive unit may arranged to move along the guide unit while the follower may move relative the drive unit.
  • One effect of this is that it will reduce the risk that the drive unit is rapidly worn out in regards of its ability to move along the guide unit.
  • the follower is pivotably movable by an angle of least 70°. Tests have shown that such angle allows for convenient loading of blanks in the magazine.
  • the follower comprises a handle for allowing an operator to move the follower relative to the guide unit.
  • the follower is arranged to interact with the sensor device such that the drive unit is activated respectively deactivated when the follower is in the feeding position respectively in the loading position. This has the effect the follower may act as switch in regarding of the operation of the magazine as the follower may be brought into either a feeding position or loading position.
  • the sensor device comprises a light emitter
  • the follower is arranged to interrupt a beam of light emitted by the light emitter when the follower is set in either the feeding position or in the loading position.
  • the drive unit comprises an actuator for imparting respectively inactivating said movement to the follower, and a switch that is operably connected to the follower and arranged to control the actuator.
  • the processing unit is configured to determine the number of carton blanks in the guide unit when the follower is moved from the loading position to the feeding position, based on the distance between the follower and the feed end, and a value representing the thickness of a carton blank.
  • the processing unit is configured to count the number of blanks that are picked from the feed end, and control the drive unit to adjust the force applied by the follower on the stack of carton blanks, in dependence of the number of blanks that are picked from the feed end.
  • the processing unit is configured to receive from the sensor device a signal indicative of a first distance between the follower and the feed end; count the number of blanks that are picked from the feed end; receive from the sensor device a signal indicative of a second distance between the follower and the feed end, after the number of blanks have been picked from the feed end; and determine a value representing the thickness of a carton blank, based on the first and second distances and the numbers of counted blanks. Such determined value representing the thickness may be used in subsequent operation of the magazine, where the value can be used for calculating the number of blanks in the magazine, and adjusting the force applied by the follower on the stack of carton blanks accordingly.
  • a second aspect relates to a packaging machine that comprising a magazine according to the first aspect, including any embodiments thereof.
  • the packaging machine is arranged to receive the carton blanks from the magazine, form packages from the carton blanks, and fill food product in packages.
  • a third aspect relates to a method performed by a magazine according to the first aspect, including any embodiments thereof.
