A weighing scale includes a weighing module having a load cell in a housing. The load cell has fixed, deformation, and movable portions. The fixed portion is connected to the housing, and the movable portion bears a spider bearing a platter. The housing is open upward in a region of the load cell. The housing is closed by the platter and by edges of the platter which protrude downward beyond the top edge of the housing. The deformation portion has a strain gauge for measuring a weight acting on the platter. A printed circuit board includes electronics for processing a signal from the strain gauge. The electronics include memory storing calibration-data of the load cell. A removable cover is fastened to the fixed portion by a first fastener secured by a calibration mark, and protects the memory of the printed circuit board against manipulation of calibration data.

A conveyor belt scales for transporting goods includes: a feed belt; a weighing belt; and a removal belt. The weighing belt is supported on a load cell that detects a weight of the goods transported by the weighing belt. The conveyor belt scales further has a metal detector, which includes a transmitter coil and a receiver coil. The transmitter coil and the receiver coil are each a planar coil.

A weighing scale has a housing accommodating a load cell, having fixed, deformation, movable portions. The fixed portion is connected to the housing, and the movable portion bears a spider having a platter. The deformation portion has a strain gauge measuring a weight acting on the platter. A strip light is attached to an external wall of the housing. A state machine of a controller depicts states of the weighing scale. The controller either: applies a voltage to the strip light in a pulsed manner when the state machine is in a first state, and applies a voltage to the strip light constantly in a second state; or applies a voltage to a third group of LED lamps of the strip light constantly in the first state, and applies a voltage to a second group of LED lamps of the strip light constantly in the second state.

A weighing scale includes a weighing module which has a housing in which a load cell is accommodated. The load cell has a fixed portion, a deformation portion, and a movable portion. The fixed portion is connected to the housing, and the movable portion bears a spider having a platter. The deformation portion has a strain gauge configured to measure a weight acting on the platter. The housing is formed as a single piece and in a trough shape. A strip light is attached to an external wall of the housing and is attached substantially all around the housing. The weighing scale further has a controller with a state machine which is configured to depict at least one technical state of the weighing scale, the control unit being configured to actuate the strip light on the basis of the state of the state machine.

A whetting device is for a slicer. The whetting device has: a whetstone that sharpens a circular blade of the slicer; a hone that deburrs the circular blade; a handle that moves the whetstone or the hone toward the circular blade; and a mount for fastening to a stop plate of the slicer. The mount has an insertion apparatus for being form-fittingly inserted into the stop plate. The mount having a U-shaped plate receptacle, which has a gap for introducing the stop plate into the gap in when the whetting device is pushed onto the stop plate. The insertion apparatus has a lug for engaging in an recess in the stop plate, or the stop plate has the lug for engaging in the recess in the insertion apparatus.

A method monitors a slicing machine, which has a circular knife driven by an electric knife motor. The method includes: sensing a knife motor current or a temporal profile of the knife motor current from the electric knife motor; determining measurement data based on the knife motor current or the temporal profile of the knife motor current; and determining a current cutting characteristic value based on the measurement data. The measurement data includes a load-dependent or load-independent current component. The cutting characteristic value includes a soiling, wear, or knife sharpness characteristic value, the soiling and wear characteristic values being derived from the load-independent current component, and the knife sharpness characteristic value being derived from the load-dependent current component.

A method operates a sales device for goods. The method includes: detecting, using a shelf with automatic removal monitoring, a removed item and determining item data of the removed item; receiving the item data of the removed item; adding the item data of the removed item to a list of items intended for payment; receiving an item number from a product scanner; adding the item associated with the item number to a list associated with the product scanner; identifying the product scanner at the sales device; collecting, with at least one sensor, data about items in a shopping cart or a shopping basket which is located on a support plate of the sales device; and validating the list of items associated with the product scanner on the basis of the data from the at least one sensor and the list of items intended for payment.

An electrically operated slicing machine cuts slices from material to be cut. The slicing machine has a slicing device, which includes an electric blade motor; a circular blade rotatably driven by the electric blade motor; and a carriage that is moved parallel to the circular blade to receive and move the material to be cut. A blade monitor monitors a condition of the circular blade. The blade monitor has a current measuring device that measures a blade motor current of the electric blade motor. A grinding monitor monitors a grinding process executed by a blade grinder.

The invention relates to a label printer for printing on a paper tape wound onto a roll, said label printer comprising a printer housing in which a reception space for the roll with the paper tape or for a cartridge comprising the roll is provided, wherein the paper tape can be placed into a paper path; a foldable housing element that is attached to the printer housing and that enables access to the reception space for the insertion and removal of the roll or the cartridge in an open position and prevents access in a closed position, wherein the state of the label printer can be detected, namely whether the housing element is closed or the cartridge is inserted and whether the paper tape is placed into the paper path. A reflection light barrier, comprising a light transmitter for transmitting a transmission light beam and a light receiver for a reflected portion of the transmission light beam, and a further light receiver for a transmitted portion of the transmission light beam are provided, with the reflection light barrier being provided at the printer housing and the further light receiver being provided at the housing element or the cartridge, or vice versa, and with, in a closed state of the housing element, the reflection light barrier and the further light receiver being arranged at two mutually oppositely disposed sides of the paper path. A control unit is configured to detect the state of the label printer based on a joint evaluation of the reception intensity of the light receiver of the reflection light barrier and the reception intensity of the further light receiver.

A bread slicer includes: a slicer housing, accommodating a slicing blade rotatable in a slicing plane, the slicer housing including: a feed chute for introducing the loaf into the bread slicer; and a receiving chute, which adjoins the feed chute except for a blade gap; and a bagging aid configured for slipping packaging over the bagging aid together with the slices of the sliced loaf resting thereon, the bagging aid having a cantilevered portion. External dimensions of the feed chute parallel to the slicing plane are greater than or equal to maximum external dimensions in directions of loaves to be sliced. External dimensions of the cantilevered portion parallel to the slicing plane are smaller than external dimensions of the feed chute parallel to the slicing plane. The receiving chute is the bagging aid having the cantilevered portion and is inside a cover of the slicer housing.
