The method according to the invention comprises the production of bakery products in a production plant. As a manufacturing plants can basically all

Manufacturing plants are used for the production of bakery products, in which several processing devices are provided. In addition to the conventional components of the manufacturing plants is for the process a

Data processing device requires, which includes a database, in the at least one processing value, in particular a plurality of processing values, each one

Product identification value can or can be assigned.

For example, the manufacturing plant may comprise devices as described in documents AT 51 1751 A1, AT 8881 U1, AT 51 1409 A1, AT 51 6485 A1, AT 410390 B, AT 413066 B, AT 149184 A, AT 378109 A and / or EP 1919292 B1 are disclosed.

The method will now be described with reference to an exemplary embodiment

described.

In the production of rolled wafer packets, which are known, for example, as consumable containers for ice cream, a sugar-containing dough, in particular a dough containing high sugar, is produced in a first step. This is applied to a baking mold via a feeder designed as a pourer. To increase the throughput, such production systems optionally have a plurality of infusers. This Aufgießer thus correspond to processing devices in the context of the invention. To identify which infuser or which

Processing apparatus for producing a particular baked product has been or will be, the product identification value of the respective baked product in Assigned to a database a processing value of the infuser. This processing value can be, for example, a value for the unique identification of the used infuser. Additionally or alternatively, the processing value of the infuser may be a parameter of the infuser - for example, how much dough

was applied or how long a valve was opened to the Teigauftrag.

The applied to the baking pan dough is subsequently to a

Baked intermediate. For this purpose, the baking system comprises several baking tongs, each baking tongs corresponds to a processing device. to

Identification of which baking tongs was or will be used to produce a particular baked product, the product identification value of a particular baked product is a processing value of trained as a baking tongs

Assigned processing device. This processing value can be, for example, an identification value for identifying the baking tongs used to produce the particular baked product.

Additionally or alternatively, the processing value may also be one of a

Temperature sensor recorded temperature value of the baking tongs. The baking chamber temperature can also be assigned to the product identification value as a separate processing value.

After passing through the baking chamber, the baking molds are opened and the

Taken from intermediates. The removal of the intermediates is preferably done via several customers, which may also be processing devices in the context of the invention. Now, an identification value of the customer can be assigned to the product identification value of a particular baked product in order to be able to unambiguously identify which customer is in the process of accepting a particular product

Baking product is or was used.

As a consequence, the intermediates are bought by the customers

Forming device for forming the intermediate product supplied. These

Forming device may be, for example, a bag rolling. Such a thing

Bag rolling mechanism comprises a plurality of rolling devices or rolling tools, wherein each individual rolling tool is set up for producing a bag and thus one Machining device according to the invention corresponds. In order to be able to identify which rolling tool was or is involved in the production of a specific baked product, a processing value of the shaping device can be assigned to the product identification value of the baked product. This processing value of the shaping device can be, for example, an identification value which provides information about which of the rolling tools of the forming device was or will be used to produce a specific baked product.

Subsequently, for example, a cutting device for machining and in particular for cutting an intermediate product contained in the baked product may be provided. Also, machining values of this

A cutting device, such as a cutting tool identification value or a parameter such as a cutter speed, may be associated with a product identification value to identify the machining.

Furthermore, if appropriate, a mass application device can be provided for applying a mass to the baked product or to an intermediate product contained in the baked product, which likewise can be considered as a processing device in the context of the invention. Processing values of the mass applicator may include, for example, the amount of mass applied, an identification value of one of a plurality of mass application nozzles or nozzles, or also that of a sensor

recorded temperature or viscosity of the applied mass.

In principle, all machining values available in the system can be assigned to the product identification values.

For quality control, according to the present embodiment, a

Be provided control interface for an operator. Through this

Operator interface can now select an operator one or more processing values.

For example, the operator may set the processing value of a particular

Select baking plate. To control the baked product is preferably a

Product output device provided by the selected baked product or the selected bakery products are removed from the manufacturing process. Through this product output device now all those products are issued, in whose production the selected baking plate was involved.

Alternatively, the operator can, for example, also select a specific rolling tool and thereby eliminate all those baked products that are in exactly this

Rolling tools have been edited.

Furthermore, as an alternative, all those baked products which have been poured, for example, by a specific dough-pourer that has been produced at a specific baking-plate temperature range and / or that has been processed by a specific gripper, can also be discharged by the operator.

The method can thus be a selective quality control of the baked products, which allows quick troubleshooting and rapid quality optimization.

Additionally or alternatively, by the method a selective

Product removal of all those baked products done to a certain

Processing value or to which certain processing values are assigned. Thus, for example, all those products can be automatically or automatically removed from the production process, that of a specific

Machining device or produced at certain processing parameters. As a result, for example, in the case of a defect of a single

Machining device all those products automatically or automatically

excluded or removed from this defective

Machining device were processed. As a result, despite a defective processing device, the production can be continued.

The product discharge can, for example, by a conventional

Conveyor or by a conventional transfer device with

Exhaust function to be realized. For example, the baked products are transported transversely to the conveying direction of a conveyor belt and fed to a packaging machine. All those products that remain on the conveyor belt and not the Are fed from the packaging machine

Production process rejected. Alternatively, a compressed air nozzle

be provided, which is activated for the product discharge of certain products, thereby removing selected baked products from the conveyor.

Preferably, a database formed as a product register is provided, in which all relevant data, for example data on tools, temperatures, etc., are defined and assigned to a product. In the course of the manufacturing process, this database or this register is continuously described with the current values.

This is a targeted query for specific product properties,

especially after processing values, possible. The discharge of the selected bakery products, for example, via a selective activation of a

Transfer blower, in particular a transfer device done.

The intended for the production of baked products different

Machining devices are usually not rigidly synchronized or clocked with each other, but have flexible customization options. Furthermore, speed fluctuations of drives may also be present.

In order to avoid assignment errors, in particular to prevent a processing value from being associated with an incorrect product identification value, a virtual register is preferably set up as the database by software. The position at which this register is written or read from this register shifts continuously depending on the current data of the individual

Processing devices. These data are preferably acquired in real time and, in particular, represent variable parameters of the recalculation which, due to the high production speeds, e.g. five products per second, for example every 10 milliseconds. However, the register adapts flexibly to the respective one

Production conditions and settings of the processing devices on. Thus, improving the robustness of the system against misallocation of

Machining values are achieved.

Optionally, the method may include the steps of identifying all of the products automatically upon identification of a malfunction of a processing device discharged or excluded from the production process that has been processed or manufactured by this processing device. As a result, despite a faulty processing device, production can be maintained, the defective products preferably being automatically discharged.

Optionally, a sensor may be provided which is adapted to detect defects in a processing device and / or the baked products.

Optionally, a plurality of such sensors may be provided. Optionally, it can be provided that one or more sensors are provided for detecting quality deviations on the product. For example, by determining the product weight, by an optical sensor for detecting surface or shape errors or by other sensors, an automated or automatic quality control of the products can be carried out. This allows

if necessary, automatic or automated faulty products are removed.

In all embodiments, it is preferably provided that the quality control and / or the product discharge during the production of bakery products can take place during normal operation or can.

In the sense of the invention, a process in which a baked product is removed from the usual processing chain of the production process is referred to as rejecting. This includes, for example, that the baked product between the

Completion and the packaging can be discharged. For example, the baked product or an intermediate product contained in the baked product can also be discharged between two production steps, in particular in the transfer device between the baking device and the forming device.

The invention will be further described with reference to a further exemplary, non-limiting, embodiment and with reference to FIG. 1.

Fig. 1 shows a schematic representation for illustrating the method according to the invention. The baked products can be prepared in a conventional manner in a manufacturing plant 1. The manufacturing plant 1 comprises several

Machining Devices 2. Machining devices 2 are, for example, molds or tools. For example, the processing devices 2 include

Baking tongs of a wafer baking machine or rolling devices for producing rolled wafer packets. In order to enable efficient quality control and / or product removal, in the present embodiment, a database 3

provided. In this database 3, database entries are created. The

Database entries include product identification values 5 and processing values 4.

According to the present embodiment, the product identification values 5, in this case the values from P1 to Pn, are assigned first processing values 4, for example values A1 to An. The values A can be, for example, baking plate numbers for identifying a baking plate. Further, according to this

Embodiments assigned further processing values B1 to Bn. These values B1 to Bn can be, for example, identification values for identifying a rolling tool of a bag rolling device.

Furthermore, as shown in this embodiment, further processing values 4, in particular C1 or C2 can be assigned. For example, the processing values A1, B1 and C1 are assigned to the first product P1. The second

For example, product P2 is assigned the machining values A2, B2 and also C1. C1 and C2 may be processing values of a processing device, for example if the baking chamber temperature is above or below a certain threshold value.

C1 and C2 may, in accordance with the present embodiment, be identification numbers of two infusers for infusion of the wafer dough. While the first two

Products P1 and P2 were infused with the infuser C1, the products P3 and P4 were poured with the infuser C2. If, for example, the quality of those products which are infused with the infuser C1 is to be checked, the desired parameter can be selected by the operator at an operator interface 7. Subsequently, the products in question in the Product output device 6 are discharged. Alternatively, these products may also remain in the manufacturing process and merely be controlled.

The acquisition and assignment of processing values 4 to

Product identification values 5 can be made by conventional means. For example, it can be determined via a time measurement which of the processing devices have processed which baked product at which time.

According to a further, not shown embodiment, the invention can be carried out as follows:

Instead of or in addition to a dedicated product identification value in the sense of a product serial number, the product identification value may also be a value for indicating the position of the product at a certain position. In this case, the database may, for example, be deducible that different products are arranged in different places in the product delivery device, the processing values of the product being assigned to this position in the database.

For this purpose, real sites of the manufacturing plant, where the baked product or the intermediate product can be located during production, may also be depicted in a database. In particular, every possible location of a processing device in the database can be taken into account.

For example, therefore, for each baking tongs, for each tool the

Rolling device and / or for all other conceivable places where the product or the baking intermediate product is transported or processed in the course of the manufacturing plant, be considered in the database storage space or data field. Now, for example, with each machine cycle, data between the

Memory locations are exchanged. In order for the correct data to be transferred, it is preferably defined how the individual processing devices are in contact with each other or how they are interlocked. This assignment can be made, for example, during commissioning of the manufacturing plant.

If necessary, this assignment is the same for several systems and can therefore already be stored in the controller. The assignment of the product identification data to a real place may entail the advantage that the data does not have to be circulated in the database. The product comes eg from the baking plate x and remains on the pickup y until it is conveyed into the roll form z. Instead of circulating all data with one machine cycle, alternatively only the handovers can be updated, for example from x to y to z. This brings a significant reduction in the required computing power. The offsets in relation to the reference position (home position) can be specified during commissioning and depend essentially on the mechanics.

For example, data can be written to the database by external processes. If necessary, these data can be read by external processes. For this, only the section and the index in the database are given correctly. For example, a light barrier is located at a certain position on a conveyor belt of the product dispenser. The data at the position of the light barrier, for example, for the detection of a blocked

Rolling tool or used for the product separation. A product is recognized - or not and compared with the record entry for the rolling tools. If products of the same rolling tool are missing several times, blockage of the tool can be assumed. The same principle can also be applied to other processing devices, such as a test station for weight, shape or color. Here, due to the traceability

Conclusions about the processing devices are made.

If a tool of a machining device is found to be invalid or defective, all products can be automatically eliminated by this tool. This procedure can also be used to determine samples for specific eligibility criteria.

For example, in accordance with the various embodiments, the product identification value may be a memory location, a field, a column, or a row of a database. This storage space, this field, this column or this row of the database can be assigned as a product identification value to a dedicated key, for example a serial serial number.

Alternatively or additionally, the product identification value, ie a value that allows the identification of a product, may also be a value or this memory location, this field, this column or this row of the database, which gives conclusions as to where the particular product is currently located Manufacturing plant is located.

For example, the product identification value may be a location indicator or positional value of the product in the product dispenser. For example, the

Processing values of a baked product strung together in database fields. Each database field corresponds to a possible location of the baked product in the manufacturing plant. Thus, the production identification value according to this embodiment is a value for localization of the baked product.

According to this position-related identification, for example, a first

Processing value to be the identification number of a baking plate. When handing over the baked waffle cake by a transfer device is also the

Information identifying the back plate in the database memory on the space corresponding to the transfer device. In doing so, a processing value of the gripper arm is added to the memory location. In the data field or storage space of the database, a baking plate number and a transfer gripper number are now stored in the present case. Furthermore, a wafer rolling tool can subsequently be fed to a tool, whereby here too the data is transferred to the place in the database which corresponds to the rolling tool processing the product. In this database memory or data field are thus according to this embodiment now the baking plate number, the number of the transfer gripper and the number of the rolling tool. Subsequently, the rolled bakery product can be transferred to the product dispenser, with the same thing happening with the data in the database. At a certain position of the product dispenser there is now a particular baked product. Likewise, a number of values corresponding to the processing values are stored in the database at this memory location. In this case, the identification takes place via the position in the product output device. For example, now all in one This can be done by identifying in the database all those products in whose dataset the identification number of the particular baking plate appears. About a device for discharging the products, these can then from the

Manufacturing process to be removed.

The product identification value may analogously be a digital consignment note in which processing devices can create entries, in particular which processing device or which tool has carried out a processing of the product and / or which parameters were used. In particular, for example, the so-called station numbers (tools) and the temperature (processing value) are entered. Each place of the plant, where a product can be located, preferably has a digital goods receipt or an entry in the database. Thus, the products are traceable and one

product-specific processing (sorting, marking, etc.) is possible.

By a further embodiment of the invention, an adjustment of the pourer of a manufacturing plant can also be carried out. Here, for example, several, for example, 10 products, can be excreted by a particular Aufgießer. These are then tested, for example, weighed, and the infuser is

adjusted or fine adjusted accordingly. The same principle can also apply to others

Machining devices and tools, such as rolling mandrels, gap dimensions of the baking plate, take-off points on the take-off arms, etc., are applied.
