Definitions
- the invention is based on a device for detecting the goods on a self-service cash register system.
- Such devices are used to capture the goods selected by a customer in a self-service department store.
- the collection of goods should be automatic, in order to be able to waive the presence of a cashier when paying for the goods.
- SeIf checkout Customer independently collects and pays the goods selected by him, without relying on the presence of a cashier, is called SeIf checkout.
- the goods are recorded with or without the support of the customer and the purchase price of the recorded goods is calculated.
- the customer then pays his purchase in cash, by debit card or credit card directly to the self-service checkout system.
- the goods are equipped with a machine-readable marking or a machine-readable code.
- the mark or the code is, for example, a one-dimensional, two-dimensional or other multi-dimensional bar code. This is also called a barcode or barcode.
- the machine-readable mark contains, inter alia, the price of the goods.
- the customer places his goods selected by him on a transport device, such as a conveyor belt.
- a transport device such as a conveyor belt.
- one or more scanning devices are arranged stationary on the transport device.
- the scanner consists of several scanning units. Each scanning unit is equipped with a source for emitting optical radiation and with a detector for receiving the radiation reflected by the goods lying on the transport means.
- the optical radiation is light of the visible wavelength range or the infrared wavelength range.
- Scanning unit generates a scanning pattern by means of pattern forming mirrors, which is imaged on the scanned goods and is reflected by the goods.
- the scanning unit also generates a signal corresponding to the reflected radiation.
- Such scanning units are also called bar code readers or scanners. Often these are so-called laser scanner modules. They transmit the optically scanned machine readable mark into electrical signals which are input in digital form as an input to a data processing unit of a self-service cash register system.
- the scanning units typically have a field of view centered about an optical axis and line of sight. Scanning devices for operated cash registers, which are equipped with a cashier, have only individual
- Target axes or fields of view They therefore require a precise positioning of the goods with respect to the scanning device, so that the machine-readable mark or the code is aligned in the direction of the scanning unit.
- Most goods are only marked with a mark in one place.
- Such scanners are not possible in self-service checkout systems that are not equipped with a cashier, and in which the goods lying on a transport device are automatically scanned, since the customer usually does not pay attention to place the goods on the transport device such that the marking on the goods points in the direction of the scanning device. Particularly difficult is the scanning of the
- Devices for detecting the goods on a self-service checkout system are therefore usually provided with multiple scanning devices
- Scanning units equipped which are arranged at different positions on and above the transport device. Such devices are also referred to as tunnel scanners.
- the individual scanning units are in this case arranged in a stationary manner over an archway that is exciting over the transport device.
- the present invention is based on the object, a device for
- Provision of goods to provide a self-service cashier system that is inexpensive to manufacture and reliably detects the machine-readable mark or the code of a product regardless of their orientation on a transport device.
- the device according to the invention with the features of claim 1 is characterized in that are arranged between or next to the plurality of scanning units laterally from and / or above the transport means mirrors. If the optical radiation emitted by the sources of the scanning units and reflected by the surfaces of the product does not impinge on a detector of one of the scanning units but on a mirror, then it is reflected by it in the direction of a detector. Even with a small number of scanning units, almost all of the optical radiation reflected from the surface of the goods is fed to the detectors of the scanning units. The machine-readable markings of the goods are thus detected in a reliable manner. Since this does not increase the number of scanning units but only a plurality of mirrors are used, the device according to the invention is inexpensive to manufacture.
- Markings on the goods are collected increased.
- the goal here is to capture the goods with a probability of 100% or nearly 100%, while increasing the speed of the acquisition process.
- the reliability or probability is also referred to as the sampling rate, read rate or scan rate.
- the device is equipped with a housing for the scanning device.
- the scanning units and the mirrors are arranged in the housing. In this way, the scanning units and the mirrors are protected from damage. Furthermore, they can not be manipulated by customers.
- the housing is arranged laterally and above the transport device and surrounds a portion of the transport device in the manner of an archway.
- the product lying on the transport device is through the opening of the archway-like
- the housing transported.
- the opening of the archway and thus the housing is so large that even large, lying on the transport goods can be passed through the housing of the scanner.
- the housing further extends in the transport direction of the transport device over a portion along the transport device and has a length in this direction.
- several scanning units in the transport direction in the housing can be arranged side by side.
- scanning units and mirrors can be arranged in the housing side by side in the transport direction. Due to the size of the housing, the distance between the arranged in the housing
- a total of four scanning units are arranged in the housing: one above the conveyor belt, one right of the conveyor belt, one left of the conveyor belt, and one below the predetermined by the conveyor belt goods transport plane.
- the additional mirrors are arranged in front of and behind the scanning units in the transport direction.
- the scanning units can also be arranged only on two sides of the housing. The two others
- the housing of the scanning device and the transport device span a space that bulges outwardly above the transport device.
- the housing is round at least in an upwardly facing portion.
- the housing and the transport device span a space perpendicular to the transport direction of the transport device has a polygonal cross-section.
- the housing consists for example of two lateral sections, which are arranged perpendicular to the transport device, and one or more sections above the transport device. The sections above the transport device can thereby run parallel to the transport device or at an angle to the plane formed by the transport device.
- the mirrors are mounted on rotatable drive shafts, which are driven by at least one drive unit. This increases the likelihood that the rays reflected from the goods will be redirected by the mirrors to a scanning device.
- FIG. 1 shows a device for detecting the goods on a self-service check system with a conveyor belt 1, a total of four scanning units. 2 and 8 mirrors 3.
- the four scanning units 2 form a scanning device.
- the scanning units 2 and the mirrors 3 are arranged in a housing 4. At the side of the housing facing the conveyor belt, the scanning units 2 and the mirrors 3 are covered by a glass plate 5, which has a high intensity for the radiation emitted by a source of the scanning units 2
- the sources of the scanning units are not shown in the drawing. Through the transparent glass plate 5, the scanning units 2 and the mirror 3 are visible.
- the scanning units 2 and the mirror 3 can be seen. On the other two sides they are hidden in the representation by the housing.
- the scanning units 2 extend over the entire width of the housing perpendicular to the transport direction of the conveyor belt first
- the conveyor belt 1 consists of two sections. A first section is at the foreground of Figure 1 and leads the goods up to the housing of the scanning units 2 and the mirror 3. A second section is located in the background of Figure 1. It supplies the goods to other stations after scanning.
- the device according to FIG. 1 is also referred to as a tunnel scanner, since the goods lying on the conveyor belt pass by the scanning units as in a tunnel.
