Description

The present invention relates to a method for reproducing data according to the preamble of claim 1, which relate to packaging goods, wherein the data is detected by a data acquisition device and transmitted to a display device. The invention further relates to a display device for packaging machines and a data acquisition device according to the preamble of claim 4, for packaging goods or for the packaging machines upstream goods conveyor which is designed as a weighing station, wherein the display device is connected to a parameter of the packaging goods detecting data acquisition device, and and wherein the display device the data received from the data acquisition device that they directly or indirectly, for. B. prepared by a computer, displays directly or in edited form.

From practice display devices for packaging machines or their upstream goods conveyors are known, which are connected to weighing stations, see for example DE 44 09 908 for packaging machines. The weighing stations weigh the packaged goods to be packaged, for example cheese, ham or sausage slices, in particular from a plurality of cheese, ham or sausage slices, which are stacked on top of one another, formed shingles, wherein the slices can be arranged directly one above the other or only partially concealing. When weighing, it is metrologically determined whether due to different product compositions of these products or due to irregularities in the cut of these products, despite a standardized number of stacked discs, the weight of a multi-disc shingle is either too high or too low.

The weighing data recorded by the weighing station are detected by a computer or computer, which in turn is connected to a display device consisting of a display panel which is arranged in the area of the packaging machine or of the upstream goods conveyors. An operator looks at the display panel, which is informed via an indication whether the packaging material arranged on the packaging material or arranged on the upstream goods conveyor Good, in this case the shingle, too heavy or too light or a correct weight, and at If the shingle is too heavy, one or more slices are removed from the shingle and, if the weight is too light, slices are added to the shingle, etc.

This type of display of measurement data of the packaged goods is disadvantageous, since the operator must always first look at the substantially vertically arranged next to the packaging machine or its feed conveyor display panel and then the data taken from the scoreboard on the goods must transmit in mind that often on the horizontal trained top of the packaging machine or goods conveyor are, which is particularly strenuous in a fast processing cycle over a long period of time and can lead to incorrect operation such that an incorrect assignment of the imaged on the scoreboard value to the packaged. In addition, the constant change between looking at the display panel to the view of the packaged goods is tiring, so that a frequent change of the operator must be made. Another A disadvantage of the known state of the art is that the display panel is located on one side of, for example, the packaging machine and therefore no operator can be located on this side of the packaging machine on which the display panel is located, but only on the side of the packaging machine opposite the display panel or their goods supplier.

The invention has for its object to provide a method for reproducing the measurement data of the packaged goods and / or a display device for parameters of products that are to be packaged by a packaging machine or to be transported by the packaging machine upstream goods conveyors in such a way that a particularly light Assignment of the displayed data of a data acquisition device to the packaged goods takes place in order to enable the fastest possible and error-free acquisition of the measured data in relation to the measured packaged goods by the operating personnel.

This object of the invention is achieved by a method for reproducing data relating to packaging goods, having the features of the characterizing part of claim 1. Advantageous developments of the method are specified in the dependent claims. Furthermore, this object is also achieved by a display device with a data acquisition device having the features of the characterizing part of claim 4. Advantageous developments of the display device are given in the dependent device claims. Features and details described in connection with the method according to the invention also apply in connection with the display device according to the invention and in each case vice versa. The features mentioned in the claims and in the description can each be essential individually or in any combination.

The method includes that the display device reproduces the data on the packaging goods themselves or their surroundings, in particular a carrier on which the packaged goods are arranged, in direct or converted form. In this case, environment means, in particular, the immediate proximity to the packaging goods. Therefore, both in the case that the data on the packaging goods themselves and in the case that the data is imaged on the environment of the packaging goods, the operator only in the direction of Look for packaging goods. A change of sight, as was required in the prior art, is eliminated. Furthermore, the operator no longer has to transfer the data read from the display device to the packaged goods as in the prior art, but can immediately associate the data with the associated packaged goods at a glance. As a result, a higher processing cycle can be achieved and maintained over a longer period of time, while still relieving the operating personnel. In addition, editing errors can be avoided by the immediate display of the data. The display device is designed as at least one projector, wherein the projector is arranged above the packaging goods.

In one embodiment of the method, the display device reproduces the data on the packaged goods themselves or their surroundings by means of a light beam. Due to the fact that stand-alone display devices can hardly be arranged on the packaging goods, it makes sense to direct a light beam onto the packaged goods. In this way, in particular, a picture on the packaging goods themselves can be made, the image is easy to create and remove.

In a further embodiment of the method, in the case of a displacement of at least one packaged good, the data are likewise shifted by the same amount and the same direction, so that the data are imaged in the same way as before on the packaged good or its surroundings. In a high processing cycle, it may happen that the packaged goods have already been removed from the place where the weight correction is to take place before the correction could take place. For example, a conveyor belt can continue to move the packaged goods to be corrected continuously or jerkily. So that the correction can also be made in this case, the display device moves the displayed data so that even in the case of a moving packaged goods, the location of the displayed data remains relatively constant relative to the associated packaged goods. The simultaneous, optical shifting of the displayed data can be done with one or more behind or side by side arranged packaging goods. For this purpose, the display device can obtain the required information from the packaging machine or the data acquisition device, which metrologically records and forwards the respective location of the packaged goods. Consequently, information technology coupling can take place directly or indirectly between the packaging machine and the display device.

The object is further achieved by a display device with a data acquisition device, wherein the display device, the data relating to the packaging goods on the packaging goods themselves or their environment, in particular a carrier on which the packaged goods are arranged, is formed reproducing. In other words, a display device is proposed which embodies the measured values obtained unprocessed or processed directly on the packaged product or its surroundings in order to display the measurement data where a change is required, ie. h., on the packaging itself or its immediate surroundings.

According to the invention, the display device is designed as at least one projector, for example a laser projector, which is arranged above the packaged goods in order to reproduce measured data in a manner appropriate to the user on or on the packaged goods. The projector can be arranged stationary above or laterally offset so that it does not interfere with the production process and yet can transmit information close to the product by emitting a light. In the following, a projector is to be understood as any light source whose light rays can strike the packaged goods or their surroundings. The projector can be a transmitted, reflected, reflected or laser projector. But it may also include the light of one or more light sources, which falls directly or through lenses on the packaged goods or their immediate environment. The projector can play back data in the form of still images and / or in the form of moving images or movies.

At the same time, the projector can simultaneously project its data onto one or more packaged goods to simultaneously provide the user with a quick overview of required corrections and to allow the user to choose in which order to make his corrections. Also, the projector can also play data that move with the goods to be packaged or tracked.

In this case, the information to be transmitted to the user can be communicated by the projector, for example by means of colors, numbers or symbols, for example by the projection of the indication "+ 2", if consisting of a shingle, for example To add several slices of cheese or two different colored symbols, for example, a green dot, if a disc is to be added and the like.

In another advantageous embodiment, the display device may also consist of one or more signal bodies which are arranged in or on the carrier for the packaged goods, for example in an advantageous embodiment in the edge region or the environment of the packaged goods, which is arranged on the carrier. In this case, the carrier may be a feed conveyor, for example an inserter, or a packaging machine, for example a deep drawing machine. A packaging machine or a feeder having, for example, a conveyor belt may have a fixed edge on which signal bodies may be arranged. This edge is in the immediate vicinity of the packaging material or the conveyor belt, so that the data can be recorded at a glance along with the packaging goods. If more than two packaged goods are processed side by side, there should also be fixed areas between tracks on which the packaged goods move. On these, the signal body can be arranged, so that even in this case, the immediate proximity of data and packaging goods is guaranteed.

The signal body (s) may, for example, be designed as lamps, for example as LEDs which may, for example, illuminate in different colors, so that depending on the number of flashing LEDs in the corresponding color of a shingle the corresponding number of panes has to be removed or added , It is also conceivable that, instead of the signal body, the desired data are displayed by means of a projector which is arranged below the packaged goods, wherein corresponding translucent areas can replace the respective signal bodies.

According to the invention, the data acquisition device is designed as a weighing station in order to detect the weight of, for example, a packaged good designed as a shingling. However, according to an embodiment not claimed, it would also be possible to design the data acquisition device, for example, as a camera or optical data acquisition device. Also, the data acquisition device not only the weight but also other properties of the packaged goods, such. Temperature, size, shape or thickness, fat content, surface finish or color Moisture content, the number of discs in a shingle or the like detect metrologically.

In an advantageous embodiment, the display device is arranged in the region of a depositor upstream of a packaging machine or in the region of the packaging machine itself. The orientation of the projector or the arrangement of the signal bodies takes place where the packaged goods are still unpacked.

In the prior art, a display panel is arranged on an edge of the carrier, so that there can be no operator here. In one embodiment of the present invention, on the other hand, it is provided that the display device is arranged and acts in such a way that workstations in the region of the display device can be arranged on several sides of the carrier of the packaged goods. For example, two operators may face each other and work on the tracks closest to them. This avoids that an operator must also correct far away from her packaged goods, so that with the invention smaller movements and thus a higher power stroke is possible.

In this case, it makes sense that the optical data emitted by a projector in the form of symbols and / or numbers and / or colors or the signal bodies are arranged so that they are easily recognizable or readable relative to the workstation to which they are associated are. This ensures that, for example, a second operator, who faces a first operator, does not have to read the numbers overhead. Signal bodies are preferably located on the opposite side of the packaged goods from the associated operator in order to avoid being covered by the operator's arms and hands.

Fig. 3

represents in a plan view another embodiment of the innovation.

Referring to Fig. 1 1 is a display device which is formed in this embodiment as a projector, the projection jets 2 is directed to the top of a packaging machine 3 together with arranged thereon, still to be packaged packaging 4. The packaging machine 4 is preceded by an insert 5, the transport ready formats the packaged goods transported in the packaging machine 3. The insert 5 in turn is preceded by a weighing station 6, in which the packaging goods, ie, the goods to be packaged are measured. In the embodiment discussed here, these are cheese slices, with several cheese slices always being arranged one above the other to form shingles. However, it should be understood that the proposed innovation can also be used for other goods to be packaged.

In the weighing station, the packaged goods 4 are weighed and the weighing station is in turn connected to a computer or other computer, which calculates whether the data obtained in the weighing station 6 correspond to the desired value. If there is a difference between the actual value and the nominal value, the calculator (not shown) calculates the quantity to be added to shingles which are too light or the quantity which has to be subtracted from shingles that are too heavy and transmits a corresponding signal to the display device 1, which corresponding Fig. 1 can be configured as a projector. This display device 1 directly projects the data onto the shingles or the packaged goods 4, so that the data on the top side of the packaged goods 4 or shingles to be packaged are readable in the sense of, for example, "+ 1" for a shingle to which to put on a disc to get the corresponding weight or "- 3" for a shingle, from which three discs have to be removed, and so on. Of course, other numbers, symbols or colors are projected onto the packaged goods in order to notify the operator 7 of the required changes to the respective packaged goods 4, so that the data of the weighing station 6 can be processed in a variety of ways or reproduced unprocessed by the display device 1.

In addition, a projection of the modification data on the carrier 8, which serves as a support for the packaged goods 4. In an advantageous embodiment, if it is not projected directly onto the packaged goods 4, the edge regions of the carrier 8 which surround the packaged goods 4 would be projected.

In the embodiment according to Fig. 1 and 2 the display device is located above the packaging machine. However, the display device 1 can also be arranged in the area upstream of the packaging machine 3 upstream feeders, for example in the area of the insert 5 or other upstream feeders or it is possible that the display device in the range of two or more machines, such as the packaging machine 3 and the insert 5, etc. is provided.

In the embodiment according to Fig. 1 projects the display device onto only two rows of packaging goods. However, it should be understood that depending on the application by the display device one, several or possibly all packaging goods 4 can be applied. This is in FIG. 2a the case.

As in Fig. 2a is shown, there is a first operator 7.1 relative to a second operator 7.2, wherein the insert 5 and the packaging machine 3 is arranged between them. This comparison is made possible by the display device 1 arranged above the packaging machine 3. Both operators 7.1 and 7.2 should be able to easily read the numerical data projected onto the packaged goods to facilitate the work as much as possible. Therefore, they are arranged so that they are arranged on the packaging goods 4.1, which are corrected by the operator 7.1, and on the packaging goods 4.2, which are corrected by the operator 7.2, in each case from the viewpoint of the correcting operator readable around. Moves a packaged 4.3, on the in Fig. 2 "-1" is pictured on the position that is up Fig. 2 the packaged 4.4 takes, so the data specified "-1" also shifts, so that even after shifting on the packaged good 4.3 "-1" is shown. For this purpose, the mapping of the data to the place to be appeared or the location of the respective packaged goods is coupled. The information required for this purpose can be supplied by the carrier 8 or the packaging machine 3 directly or indirectly via the data acquisition device 6 or a computer to the display device 1.

According to the further embodiment according to Fig. 3 For example, instead of a projection device, it is possible for the display device 1 to be formed by the signal elements, which are formed, for example, laterally to the packaging goods arranged on the packaging machine 3. In this embodiment, it is lights that are arranged adjacent to the resting on the carrier 8 packaged goods 4, wherein in this embodiment, in each case a plurality of lights are assigned to a packaged 4. These lights can be designed, for example, as LED lights and light up different colors, so that, for example, when a green light a lamp of the operator 7 is informed that a disc must be placed on the adjacent packaged 4 or at a flashing of three red lights 9 three slices of the adjacent packaged goods must be removed and so on.

Again, a corresponding display device 1 can be provided in the region of the packaging machine 3 or in its upstream feeders, such as the insert 5. The lights 9 are arranged in the immediate surrounding or edge region of the packaged goods 4 in the region of the carrier 8. Instead of a lamp or a light as a display device, any other suitable type of display devices may be used, such as a mechanical device by using height-adjustable display bars and the like.

In the Fig. 1 Illustrated display device as a projector can be, for example, a laser projector, a projector, a projector for LED font and the like.

Any features and / or advantages resulting from the claims, the description or the drawing, including constructional details, spatial arrangements and method steps, can be essential to the invention, both individually and in the most diverse combinations. It should also be mentioned that the present invention is not limited to cheese or sausage products as packaging goods. Of course, other packaging goods, such. As fruit, vegetables or mechanical, electrical, medical products or the like are processed.
