Abstract:
In a method for manufacturing movable products, at least one substrate to be processed into the product is provided with an identification that is generated from parameter values of the product to be manufactured in accordance with a rule. This rule is so bijective that identical parameter sets always lead to the same product code incorporated into the identification, and that the product parameter set, on which the identification is based, can be reconstructed from the identification at any time.

Description:
BACKGROUND 
       [0001]    The present invention relates to a method for manufacturing movable products as well as to an associated system. 
         [0002]    In the manufacture of movable products, routing slips containing the required manufacturing information are attached to the substrates from which the products are manufactured, e.g. semi-finished products. Such routing slips usually contain a drawing of the finished product, a working program, as well as order-related data such as the production deadline and the required quantity of identical products. Such a routing slip accompanies the product or the products during their manufacture and is used as the basis for the processing carried out in the different processing stations. 
         [0003]    In the manufacture of complex products that require a plurality of processing steps, the routing slip has to be read and interpreted by personnel with corresponding frequency. This is very time-consuming and involves numerous sources for reading and interpretation errors. Another disadvantage can be seen in the risk of losing the allocation between the substrate or semi-finished product and the routing slip before the product is finished, whereby at least a significant amount of additional time has to be invested in such instances. 
         [0004]    In order to solve these problems, it is known to provide substrates or semi-finished products with an identification that is usually printed on in the form of a barcode or attached in the form of an adhesive tag_that carries a barcode. Information on the product to be manufactured and the associated production order is retrieved from a database with the aid of this identification in that the identification contains the designation of a corresponding data set. For this purpose, the production planning department stores a data set for each production order in this database. However, the manufacturing process of a product is frequently distributed over multiple production sites and different companies. This requires a corresponding number of databases, which have to be established and managed manually and respectively contain an indefinitely growing number of data sets, such that the administrative effort is correspondingly high. 
       SUMMARY 
       [0005]    The present invention is directed to a method and system in which at least a few disadvantages of known systems are eliminated. 
         [0006]    According to the presently disclosed method, a first step is to determine the values of parameters that are relevant to the manufacture of the product and describe the product, and to combine these parameters into a product parameter set. In another step, a suitable device converts the product parameter set into a product code that identifies at least one substrate required for the manufacture of the product. In this case, the generation of the product code follows such a clear rule that identical product parameter sets are inevitably mapped in the same product code and the product parameter set on which the product code is based, can be determined from the product code with an inverted application of this rule. In this way, manufacturing information on required properties of the product to be manufactured of this substrate can be obtained from the product code. 
         [0007]    Prior to the further processing of the substrate, the identification is scanned and setpoint settings for manipulated variables of the device for processing the substrate are determined from the information obtained from the identification. The information obtained from the identification is transmitted to a control unit of the device processing the substrate and used by this control unit in the form of setpoint settings for controllable adjusting mechanisms and controllable drives of the device in order to modify their manipulated variables and to process the substrate. Consequently, the substrate is processed in accordance with information that is obtained from the identification and corresponds to the initially obtained parameter values describing the product to be manufactured. 
         [0008]    Since the substrate to be processed in order to manufacture the product carries the product description, the allocation between the substrate and the product description can only be lost if the identification is destroyed, wherein the clarity of the conversion rule for the product parameter set and therefore of the product properties in the product code and the identification makes it possible to reconstruct the original product description from an arbitrary identification at any time and any location as soon as the conversion rule is known and without requiring any further information. The recovery of the production-relevant product description is not dependent on the specification of the production system or the producing company such that the transfer of a manufacturing order or partial order is significantly simplified. 
         [0009]    It is preferred that the product parameters can only assume discrete values, whereby this leads to a finite number of possible product parameter sets and therefore a finite number of possible product codes. Depending on the incrementation of permitted values, it is possible to limit the size of the product code to a desired dimension on the one hand and to limit the number of possible product codes on the other hand. In this case, the exclusion of nonsensical values from the permissible range leads to an additional limitation. 
         [0010]    In a preferred embodiment, the product code is characterized by the arrangement of a plurality of alphanumeric characters because these characters can be easily processed electronically. The identification is preferably scanned by means of a reading device of the production system such that information no longer has to be visually read and manually transmitted by personnel and a corresponding automation can be realized. 
         [0011]    All processes from reading in the identification by means of a reading device of the production system up to the manipulation of the substrate by the processing device, particularly the generation of setpoint settings from the information contained in the identification in order to adapt manipulated variables of the controllable drives and the controllable adjusting mechanisms of the processing device to the product to be manufactured, are advantageously carried out in an automated fashion. It is also possible to realize an automated control by comparing the generate characteristics with the parameter values recovered from the identification. 
         [0012]    According to a first enhancement, the identification is formed by an optical marking on the substrate. A number of suitable and inexpensive sensors for reading optical characteristics are commercially available. In addition, an optical marking makes it possible to resort to a visual reading in case of defects or for control purposes. 
         [0013]    According to an alternative second enhancement, the identification is formed by a radio tag. The radio tag may also be arranged at a location of the substrate that is not visible or only visible to a limited degree, wherein said radio tag may in addition to the aforementioned identification fulfill other functions relevant to the production and/or use of the product such as, e.g., monitoring the temperature ormoisture. 
         [0014]    In an advantageous embodiment, the rule for converting a product parameter set into a product code comprises a predefined allocation of the code to the parameter set. This allocation is stored in a database, which can also be used for easily recovering the product parameter set from the product code due to the bijective allocation. This database preferably contains the entirety of allocations of all permissible product parameter sets such that its subsequent expansion is unnecessary. 
         [0015]    In an alternative embodiment to the database, the rule is formed by a computer-implemented algorithm that generates the allocations. The storage space required for this algorithm is not dependent on the incrementation and the number of permissible parameter values such that this algorithm is particularly suitable for small to infinitesimal incrementations and very large quantities of permissible values. 
         [0016]    When several substrates that form the same product are collectively processed, it is possible to provide only one of the substrates with the identification derived from the product parameter set, whereby setpoint settings for other substrates forming the same product can also be derived from this one identification. In this way, the effort for the identification and its readout can be reduced and, in particular, the number of required reading devices can be minimized. 
         [0017]    It is preferred that the control unit of the processing device is connected to an entity, which makes available the rule for the conversion of the product parameter set into a product code, by means of a remote data transmission device such that several processing devices, which may also be located at different production sites, can access the same source of the conversion rule. In this way, the overall storage space for the rule can be reduced. If the rule has to be revised, it is furthermore possible to carry out this revision centrally and it is ensured that all connected processing devices use the same rule with the same revision status. 
         [0018]    The data flow is realized by transmitting electric signals via data cables. In this way, the data flow can be achieved in a particularly simple fashion and secured against interferences in the data transmission with conventional measures. 
         [0019]    The data flow is alternatively realized by transmitting electromagnetic signals that lie in the visible spectrum via optical devices such as, e.g., optical waveguides. Radio links may also be used if the signals lie in the invisible spectrum. In this way, even great spatial distances between the production system and the device making available the rule for converting the product parameter set into a product code can be realized and the number of devices, which make available the rule for a plurality of production systems, can be minimized. 
         [0020]    It is furthermore possible to realize a combination, in which the information is in certain sections transmitted in the form of electric signals and in other sections in the form of electromagneticsignals. 
         [0021]    According to a first embodiment, the remote data transmission device comprises a directional connection to a computer center that makes available the rule for converting the product parameter set into a product code. In this way, the time required for the data exchange can be minimized with high transmission reliability. 
         [0022]    According to a second embodiment, the remote data transmission takes place non-directional to an Internet server that makes available the rule for converting the product parameter set into a product code. This makes it possible to utilize the existing infrastructure of the Internet and to minimize the expenditures for the data transmission. 
         [0023]    According to a preferred enhancement, the product code is expanded into an order code, which is used as identification of the substrate, with order-related information such as, e.g., the number of units to be manufactured, the production deadline and/or the recipient. In this way, the substrate can carry all production- and order-relevant information such that the automation of the additionally enhanced product manufacture can additionally enhanced.

     DETAILED DESCRIPTION 
       [0032]      FIG. 1  shows an example of a first production system  70  that is respectively used in print finishing or the production of book cases and comprises a casemaker  1 . The production system features a control unit  60  that transmits setpoint settings  111 . 1 - 111 . k  to the casemaker  1  in order to adapt its manipulated variables  110 . 1 - 110 . m . A reading device  50  of the production system  70  scans the barcode  5 , which represents an order code  103  and is applied onto the blank  4 ,  4 ′ to be covered being supplied as illustrated in  FIG. 4 . 
         [0033]    The reading device  50  comprises a camera and transmits the acquired order code  103  to the control unit  60  connected thereto. 
         [0034]    The production system  70  furthermore features a remote data transmission device  81  that allows the bidirectional data exchange between the control unit  60  and a computer center  83  arranged outside the production system  70  via a direct data link  85 . The production system  70  transmits the order code  103  acquired by the reading device  50  to the computer center  83  via the remote data transmission device  81  and in turn receives the product parameter set  101 , on which this order code  103  is based, from said computer center. 
         [0035]    For this purpose, the computer center  83  comprises a database  61  that contains data sets of permissible product parameter sets  101 , as well as product codes  102  and order codes  103  assigned to these product parameter sets. In addition, the computer center  83  features an order translation device  80  that uses the received order code  103  for determining the product parameter set  101 , on which this order code is based, with the aid of the database  61  and makes this product parameter set available to the production system  70  via the remote data transmission device  81 . The order translation device  80  of the computer center  83  is also capable of generating order data from the order code  102  and transmitting this order data to the production system  70 . The computer center  83  furthermore features a product translation device  9  that determines the corresponding product parameter set  101  from a received product code  102  comparable to the order translation device  80 . 
         [0036]    In order to obtain the setpoint settings  111 . 1 - 111 . k  for the controllable drives  62 . 1 - 62 . 3  and controllable adjusting mechanisms  63 . 1 - 63 . 5  of the casemaker  1  required for the production of the book case  8  from the received product parameter set  101 , the control unit  60  of the production system  70  contains a production translation device  71  that is assigned to the casemaker  1 . 
         [0037]    A second production system  70 ′ is also illustrated in  FIG. 1  and comprises two casemakers  1 ′ and  1 ″ that respectively correspond to the casemaker  1  of the above-described first system  70 . Reading devices  50 ′ and  50 ″ are respectively assigned to each of these casemakers  1 ′ and  1 ″ in order to scan a barcode  5  of the respectively supplied blank  4 ,  4 ′ to be covered and to transmit this barcode to the control unit  60 ′ of the second system  70 ′. Analogous to the first production system  70 , the second system  70 ′ also comprises a remote data transmission device  81 ′ for transmitting the code  102  acquired by the reading devices  50 ′,  50 ″ to the same computer center  83  in order to recover the product parameter set  101 . 
         [0038]    In the second system  70 ′, the acquired barcodes  5  contain a product code  102  rather than an order code  103  as it is the case in the above-described first production system  70 . This order code  103  comprises the information on the book cases  8  to be manufactured that is contained in the product code  102 , as well as additional information on order data such as, e.g., quantity, deadline and client. A control unit  60 ′ of the production system  70 ′ transmit the product code  102  acquired by its reading devices  50 ′,  50 ″ to the computer center  83  via a remote data transmission device  81 ′ and in turn receives the product parameter set  101 , on which this product code is based, from the computer center. 
         [0039]    The second production system  70 ′ furthermore features another data link  86  for accessing a data storage unit  84  via the Internet. Analogous to the database  61  of the computer center  83 , the data storage unit  84  makes available the required information for respectively determining the corresponding product parameter sets  101  from product codes  102  or order codes  103 . 
         [0040]    The algorithm  90  containing the conversion rule may be made available by the computer center  83  and/or the data storage unit  84  rather than by a database  61 . This algorithm  90  is respectively used by the order translation devices  80  and the product translation devices  9  for converting product parameter sets  101  on the one hand and product codes  102  or order codes  103  on the other hand into one another. For this purpose, the control unit  60 ′ of the production system  70 ′ comprises the functionalities of the translation devices  9 ,  80 . 
         [0041]    With reference to  FIG. 7 , a representative algorithm  90  for converting the product parameter set  101  into an identification code  102  is: “Round all values of parameter  100 . 1  to  100 . 7  scaled to millimeters to integer; write them each in three digits directly behind each other in the order &lt;width of the cover ( 100 . 1 )&gt;, &lt;height of the cover ( 100 . 2 )&gt;, &lt;width of the spine strip ( 100 . 3 )&gt;, &lt;thickness of cover ( 100 . 5 )&gt;, &lt;distance of board to spine strip ( 100 . 6 ) and width of turning in ( 100 . 7 ); prefix the typus of product in three digits.” 
         [0042]    The identification code  102  becomes 001388265024003007018 in this example: 
         [0043]    001xxxxxxxxxxxxxxxx names product typus (parameter is 1 for standard book cover), 
         [0044]    xxx388xxxxxxxxxxxxxxx names width of cover  8  ( 100 . 1 ) is to be 388 mm (387.8 mm rounded to 388 mm), 
         [0045]    xxxxxx265xxxxxxxxxxxx names height of cover  8  ( 100 . 2 ) is to be 265 mm (265.3 mm rounded to 265 mm), xxxxxxxxx024xxxxxxxxx names width of spine strip  3  (100.3) is to be 24 mm (24.2 mm rounded to 24 mm), 
         [0046]    xxxxxxxxxxxx003xxxxxx names thickness of cover  8  (100.5) is to be 3 mm (3.2 mm rounded to 3 mm), 
         [0047]    xxxxxxxxxxxxxxx007xxx names distance board  2  to spine strip  3  (100.6) is to be 7 mm, 
         [0048]    xxxxxxxxxxxxxxxxxx018 names width of lateral turning in (100.7) is to be 18 mm. 
         [0049]    For using common and therefore cheap bar code readers the identification code  102  is printed onto the blank  4  in the form of a barcode  5 : In this example the reading device  50  shown in  FIG. 1  and in  FIG. 4  is a bar code reader reading the bar code  5  printed onto the blank  4 . It gives the product identification code  102  read out from the bar code  5  to the control unit  60 . 
         [0050]    For positioning the circular knives of the lateral trimming devices  51  the control unit  60  calculates the target value from digits  3  to  6  and  10  to  21  of the identification code  102 . In this example the width of the blank  4  is to be

         [0051]    The algorithm for calculating the target value of the knife positioning adjusting unit  63 . 5  is given by the unit&#39;s  63 . 5  structural design. By way of example the drive is connected to the circular knifes via a gear having a gear ratio of  100  and a spindle drive having a thread pitch of  16 . The initial position is given by the center line, so there is no offset. Thus the translator  71  being incorporated by the control unit  60  uses the algorithm:

         [0052]    The example of  FIG. 7  uses a representative algorithm and product parameter set to illustrate converting a product parameter set  101  into an identification code  102 . The algorithm can be reversed to recover a product parameter set  101  from the product identification code  102 . The product parameter set  101  may contain different parameters and/or a different amount of parameters. Also the identification code  102  may differ in size and/or typus as well as the barcode  5 . Further, the identification code  102  and/or the barcode  5  may include additional information not given by the product parameter set  101 . 
         [0053]    The data flows of the production systems  70 ,  70 ′ are illustrated in  FIG. 5  and in  FIG. 6 . Both instances begin with the determination of the parameter values  100 . 1 - 100 . 5  of the book case  8  to be manufactured, wherein these parameter values are combined into a product parameter set  101 . In the method illustrated in  FIG. 5 , a product translation device  9  directly generates a product code from the product parameter set  101  by utilizing the available algorithm  90 . Alternatively, the product translation device  9  utilizes a database  60  that is illustrated with broken lines and in which the bijective allocations between product parameter sets  101  and product codes  102  are stored. In the alternative method illustrated in  FIG. 6 , in contrast, an order translation device  80  generates an order code  103  from the product parameter set  101  and an order data set  104  obtained from previously determined parameter values of the associated production order. 
         [0054]    In both instances, the obtained code  102 ,  103  is converted into an identification of the blank  4 ,  4 ′ to be covered in that it is applied onto the blank  4 ,  4 ′ in the form of a barcode  5  by means of a printing device  82 . This barcode  5  is respectively acquired by a reading device  50 ,  50 ′,  50 ″ assigned to the casemaker  1 ,  1 ′,  1 ″ and the obtained information is transmitted to a data processing device  71  for further processing in order to generate setpoint settings  111 . 1 - 111 . k  for the adjusting mechanisms  63 . 1 - 63 . 5  and the controllable drives  62 . 1 - 62 . 3 . According to  FIG. 1 , this data processing device  71  may be divided into the control unit  60 ,  60 ′ of the production system  70 ,  70 ′ and a product translation device  9  or order translation device  80  because individual properties of the production systems  70 ,  70 ′, as well as their casemakers  1 ,  1 ′,  1 ″, are also incorporated in addition to the product-related data. In order to convert the acquired barcode  5  into the setpoint settings of  111 . 1 - 111 . k , the data processing device  71  utilizes a database  61  as described above with reference to  FIG. 1  or an algorithm  90  of the type illustrated in  FIGS. 5 and 6  or a combination of an algorithm  90  and a database  61 . 
         [0055]    The setpoint settings  111 . 1 - 111 . k  are used by the adjusting mechanisms  63 . 1 - 63 . 5  and the controllable drives  62 . 1 - 62 . 3  of the casemaker  1 ,  1 ′,  1 ″ for adapting the manipulated variables  110 . 1 - 110 . m  or directly for the operation of the processing devices  11 ,  13 ,  23 ,  24 ,  26 ,  27 ,  40 ,  43 ,  51 ,  52 . 
         [0056]    In order to elucidate these circumstances,  FIGS. 2-4  show a casemaker  1 ,  1 ′,  1 ″ of the production systems  70  and  70 ′, in which book cases  8  are manufactured by assembling cover boards  2  and spine strips  3  on blanks  4  to be covered. One respective blank  4  to be covered is removed from a blank magazine  11  and fed to a blank cylinder by a clamping belt conveyor  17  of a blank feeder mechanism  10 , wherein said blank cylinder takes hold of the blank  4  to be covered with grippers, guides the blank past an application roller of a gluing station  13  and ultimately rolls the blank onto two synchronously supplied cover boards  2  and one spine strip  3  in the assembly point. 
         [0057]    Pressing rollers  15  press the boards  2 ,  3  onto the blank  4  to be covered in the assembly point and a reciprocating suction beam transfers the assembled book case  7  from the roll-down device formed by the blank cylinder and the pressing rollers  15  to a turn-in and pressing station that consists of a head/foot turn-in station  40  and the lateral turn-in station  43  for turning in the protruding edges of the blank to be covered, as well as a pair of pressing rollers  45  for firmly rubbing down the cover boards  2 ,  3  onto the blank  4  to be covered. The finished book cases  8  are stacked in a delivery station  46 , from which they are then manually removed. 
         [0058]    The cover boards  2  are located in a board magazine  23 . The respective bottom cover boards are ejected by a board pusher  21  of a board feeder mechanism  20  and transferred into an intermediate position, from which they are fed to the assembly point by another board pusher  21  while being aligned on outer board guides  29 . The board pushers  21  are coupled at a fixed distance from one another and moved forward and backward in accordance with the production cycle with a constant transport stroke  22  corresponding to this distance. 
         [0059]    The spine strips  3  are advanced by the board pushers  21  in a guide channel  30  that can be adjusted to the corresponding spine strip width  100 . 3  by means of the barcode  5  in the above-described fashion, wherein the spine strips  3  are introduced into the guide channel  30  extending beyond the board magazine  23  downstream of this board magazine  23 . A spine strip web  6  consisting of a flexible center strip roll is pushed into the guide channel  30  transverse to the board feed direction by a center strip feeder mechanism  24 , as well as severed from the spine strip web  6  with the corresponding spine strip width  100 . 3  by means of a cutting device  26  and thereby completely transferred into the guide channel  30 . The coupled board pushers  21  transport the severed spine strip  3  into a position within the board magazine  23 , from which it is transported onward up to the roll-down device together with the cover boards  2  with the third and the fourth transport stroke  22  of the board pushers  21 . 
         [0060]    The spine strip  3 ′ severed from the spine strip web  6  may be slightly longer than the required spine strip length. The respective spine strip length is defined by the book case height  100 . 2  and realized by cutting off a waste section on one side by means of a cutting device  27  arranged on the guide channel  30 . 
         [0061]    The conversion of the casemaker  1 ,  1 ′,  1 ″ for its adaptation to different formats of the book case  8  to be produced takes place while the machine is running and book cases  8  are still processed. A respective adjustment is carried out as soon as soon as the respective processing of the previous book case  7 ,  8  or book case parts  2 ,  3 ,  4  is completed, i.e. the required adjustments are not carried out simultaneously with the pass of the book cases and book case parts, but rather successively. 
         [0062]    The adjustments are carried out in a motor-driven fashion by means of adjusting mechanisms  63 . 1 - 63 . 5  and coordinated by a central control unit  60 . Adjustments  110 . 4  with respect to the open width  100 . 1  of the book case  8  can be realized by respectively positioning the outer board guides  29  and the lateral turn-in devices  44  accordingly by means of adjusting mechanisms  63 . 2  and  63 . 4 . The adjustment  110 . 4  takes into account the spine strip width  100 . 3 , wherein the width of the guide channel  30  is varied by means of an adjusting mechanisms  63 . 1  whereas a respectively required spine strip width  100 . 3  of the spine strip  3  is supplied due to a modified feed stroke of a controllable drive  62 . 2  that is connected to the pair of pull-off rollers. The changing open width  100 . 1  of the book case  8  is compensated with respect to the fixed blank width  100 . 4  of the blank  4  to be covered with a modified turn-in width in the lateral turn-in station  43 . 
         [0063]    In order to manufacture book cases  8  with different heights and/or open widths  100 . 1 , different sizes of cover boards  2 ,  2 ′ are in the exemplary embodiment made available in two board magazines  23  arranged along the board feeder mechanism  20 , wherein the cover boards  2 ,  2 ′ can be selectively removed from the first or the second board magazine  23  by the board pushers  21  in accordance with the respective book case size to be manufactured. The arrangement of additional board magazines makes it possible to further enhance the flexibility and variance of different sizes of book cases  8  during the production. However, the uninterrupted processing of different sizes of cover boards  2 ,  2 ′ can also be realized by stacking the different cover boards  2   2 ′ in only one board magazine, e.g. in the board magazine  23 , in the sequence in which they are processed. 
         [0064]    In the casemaker  1 ,  1 ′,  1 ″ shown, the leading edge of the cover boards  2 ,  2 ′ and spine strips  3  is defined as a fixed reference edge by the front edge stops of the board magazines  23 , which are rigidly arranged on the machine frame. The processing of cover boards  2 ,  2 ′ and spine strips  3  with different heights therefore requires a format adjustment  110 . 1  of the stroke position of the constant transport stroke  22 , wherein this format adjustment is realized in the form of an electronic adjustment of a servomotor  62 . 1  provided for driving the board pushers  21 . In addition, the book case height  100 . 2  is adjusted in the head/foot turn-in station  40 , wherein the position  110 . 3  of a foot turn- in device  42  is modified relative to a head turn-in device  41 , which is rigidly arranged on the machine frame, by means of an adjusting mechanism  63 . 3 . 
         [0065]    Left and right corner cutters  52  are arranged along the blank feeder mechanism  10  in order to cut off corner sections with a width  100 . 5  on the leading and trailing edge during the pass of the blanks  4  to be covered. The rotative tools of the corner cutters  52  are driven by a servomotor  62 . 2 , by means of which the corner section width  100 . 5  can be electronically adjusted in accordance with the respective height  100 . 2  and open width  100 . 1  of the book cases  8 . 
         [0066]    Furthermore, left and right lateral trimming devices  51  with driven circular knives are arranged along the blank feeder mechanism  10  in order to cut off lateral edge sections of wider blanks  4 ′ to be covered during the pass of the blanks  4 . An adjustment  110 . 5  is provided in order to achieve the respectively required blank width  100 . 4  and realized by positioning the pairs of circular knives of the lateral trimming device  51  relative to one another in accordance with the respective blank width  100 . 4  by means of an adjusting mechanism  63 . 5 . In this way, different sizes of blanks  4  to be covered can be cut from supplied standard sizes of blanks  4 ′.
