Definitions

  • the invention relates to a discharge station for carton blanks with the features of the preamble of claim 1, an apparatus for producing and / or processing carton blanks having the features of the preamble of claim 8 and a method for rejecting defective carton blanks with the steps according to the preamble of claim 9 ,
  • carton blanks are produced from a variety of cardboard materials in a series of processing stations. Such carton blanks usually go through in manufacturing plants stations in which they are cut, punched, folded, glued or printed. In these processing steps, it can happen that errors in the carton blanks arise or carton blanks with poor quality arise. Therefore, it is known in such manufacturing plants for the production of cardboard blanks to provide a so-called discharge station at the end of the production line, by means of which Defects in the carton blanks or carton blanks are detected with inadequate quality and by means of which these carton blanks can be automatically removed from the manufacturing process.
  • the discharge station is regularly at the end of the various processing stations and before a stacking station, on which the carton blanks produced are transported.
  • a known such discharge station for defective carton blanks is in the DE 43 17 042 C1 described.
  • the discharge station known therefrom has a series of upper and lower conveyor belts, between which the carton blanks are conveyed along a conveyor line.
  • a second conveyor line is provided here, which branches off at an acute angle from the main conveyor line, as well as a mechanical flap, which can be opened by means of a pivot drive towithzuschleusen the identified as defective carton blank in the second conveyor line.
  • the flap is coupled to an opposite guide element, which is moved together with the flap via a pivot drive in the first conveyor line so that the carton blanks in a Ausschleusumble, ie a second and thereof angled off branching conveyor line, are passed.
  • This known discharge station with an interposed between the trigger belts and the conveyor belts flap mechanism works satisfactorily at relatively low processing speeds and flexible carton types.
  • this known discharge station does not work satisfactorily.
  • stiffer blanks with wall thicknesses of, for example, a few centimeters at high transport speeds, such as on the order of 5,700 mm / s and more, not in time can be derived by the flap mechanism.
  • the distance between successive individual carton blanks is usually only a few centimeters, for example of the order of 100 mm, so that such a flap of a mechanical discharge station would have to open in 18 ms at the speed indicated above.
  • the flap mechanism of this known Ausschleusstation is too slow, so that in such cases incorrect carton blanks are unintentionally stacked by the subsequent stacking station on a stack together with error-free carton blanks.
  • a device for discharging defective printed carton blanks in which an upper pivotable deflecting element and a lower, opposite deflecting element are operated together via a servo motor and an eccentric.
  • the lower deflector is provided with a spring so that it is directly actuated against the spring force by the pressure from the upper deflector.
  • the deflection elements are connected to each other here by means of a shaft. The jointly actuated two deflection elements provide an exact and well reproducible discharge path.
  • this known discharge device has disadvantages in terms of speed in the reaction and the efficiency of discharging differently sized carton blanks.
  • a deflecting device in the form of a mechanical flap is provided after various processing stations for producing corrugated board and a plurality of error detectors. On the basis of the detectors, the discharge device is controlled in dependence on the time required for adjusting the flap.
  • DE 10 2005 055 364 A1 relates to an apparatus and a method for conveying arched objects that can be stored on different storage stacks.
  • an adjustment of the conveyor belt is provided in different pivot positions so that can be changed from a first discard pile to a second discard pile when the maximum and detected by sensors stack height is reached.
  • the present invention is based on the object to provide a discharge station for manufacturing equipment carton blanks and a corresponding method and a manufacturing device, which allow safe even at increased transport speeds and stiffer cardboard blanks of rejected as defective cardboard blanks.
  • the discharge station according to the invention for a production apparatus for producing and / or processing carton blanks has at least one upper conveyor belt and a lower conveyor belt, between which the carton blanks are conveyed along a conveyor line, and at least one upper take-off belt and a lower take-off belt, which in the direction of the conveyor line lie behind the conveyor belts, as well as means for detecting defective or with poor quality produced carton blanks, with a Ausschleusrange diagonally branched off from the conveyor line.
  • the discharge station according to the invention is characterized in that at least one of the conveyor belts is provided with a deflection, by means of which the conveyor belt is at least partially adjustable as a kind of flap band from the direction of the conveying path in the direction of the Ausschleusrange.
  • the discharge process can be performed at high speed and low inertia, so that too at higher speeds of the conveyor belts and thus high throughput the production machine for carton blanks a safe removal of defective carton blanks is guaranteed.
  • the deflection causes an at least partial adjustment of the direction of at least one of the conveyor belts.
  • the at least one deflection which causes an adjustment of the conveyor belt
  • a kind of kicker in the form of a circumferential hook can be used as an alternative to a handlebar for this purpose.
  • the cooperating with the conveyor belt deflection is provided with corresponding adjustment as a drive motor or the like.
  • Conveyor belts or take-off belts in the sense of the present invention are also roller conveyors or roller conveyor sections, as well as analogous means with which carton blanks can be transported.
  • both the lower conveyor belt and the upper conveyor belt on a deflection by means of which the conveyor belts as a kind of flap band in the direction of the Ausschleusrange adjustable are, wherein the lower deflector and the upper deflector are formed to operate independently of each other can. Due to the upper deflection and the lower deflection, which can be operated independently of each other, the conveyor belts of the discharge station, which are adjustable as flap bands, can be flexibly folded in the direction of the removal path. In this way, the reaction time for the discharge of defective carton blanks can be further increased.
  • the lower deflector and thus the lower conveyor belt can be moved immediately in the direction of the Ausschleusumble, even if the upper deflector still remains in the home position to the previous "good" carton blank, which is with a rear end still at the level of the discharge station, not to be damaged by the adjustment.
  • the independent actuation of the respective deflections which are advantageously designed as swiveling steering elements and interact via rollers or the like with the conveyor belts, can be flexibly controlled depending on the situation.
  • the lower deflection on the lower conveyor belt on three pivotable arms, which are individually and independently adjustable.
  • the Ausschleusweg can be flexibly adjusted to allow adaptation to different sized carton blanks. For example, with relatively short carton blanks, only the foremost handlebar or preferably only the two foremost handlebars can be adjusted while the rearmost of the three links of the deflector remains in its basic position.
  • the third link For larger carton blanks can be adjusted with the discharge station according to the invention, the third link, so that a larger opening in the direction of the Ausschleusstart is provided.
  • the take-off belts of the discharge station are adapted to be operated at least temporarily at a higher speed than the flap or conveyor belts. Due to the higher speed of the take-off belts or take-off rolls in relation to the conveyor belts in front of them, the carton blank, which is in each case in the conveying direction, is literally pulled off the following carton blank. This leads to an automatic and advantageous enlargement of the intermediate distance between the rear end of the one Carton blank and the beginning of the next carton blank. The increased distance between successive carton blanks also increases the amount of time within which the rejection operation must occur. Even with this measure, overall higher process speeds than in the prior art can be realized, and critical carton blanks, such as carton blanks having a large thickness or longer blanks, can be effectively led out of the process quickly upon detection of a defect.
  • the means for detecting the relative position of cardboard blanks may preferably be provided as non-contact optical sensors.
  • the position detection means according to the invention serve on the one hand for detecting the position of the respective carton blanks within the discharge station and in particular for detecting whether a rear end of a carton blank is still at the level of the conveyor belts or flap bands or is already fully retracted outside into the subsequent take-off section.
  • the conveying path can be adjusted in the direction of the removal path directly and quickly for the subsequent defective carton blank.
  • the Position detection sensors according to the invention also serve advantageously for determining and determining a distance between two successive carton blanks in order to be able to calculate the existing reaction time for carrying out the rejection process.
  • a control is provided by means of which the conveying speed of the take-off belts of the take-off section can be temporarily increased in response to input signals.
  • information from the position detection means can serve as input signals.
  • the distance can be increased to a sufficient size with the temporary increase in the conveying speed of the take-off belts.
  • the signals from a quality monitoring station can serve as input signals for the control for increasing the conveying speed. If, for example, an error is detected on a carton blank via an optical camera or the like, the speed can be increased in a targeted manner for a short time in order to facilitate and facilitate the rejection of this defective carton blank.
  • the invention also relates to a device for producing and / or processing cardboard blanks, in particular for Packaging cartons, comprising at least one processing station and with a subsequent discharge station, via which defective carton blanks can be discharged, wherein means for automatically detecting defective carton blanks are provided and wherein the device is characterized in that it comprises a discharge station according to one of claims 1 to 7 has. Because of the discharge station according to the invention, the device can be operated at a higher conveying speed than has hitherto been possible in the prior art, so that the output capacity of the production system as a whole can be increased. Nevertheless, a safe and effective quality inspection with a discharge of all defective carton blanks is made possible with the invention.
  • the invention also relates to a method for discharging defective carton blanks with the features of claim 9.
  • defective carton blanks within a machining and / or manufacturing process, for example in the production of packaging cartons safely be discharged, the carton blanks after a Be examined for their quality and possible errors and automatically be removed from the process in the detection of errors or quality defects.
  • means for detecting the relative position of the carton blanks branch off from one of the conveyor line Ausschleusstart provided as well as at least partially pivotable flap bands or conveyor belts in a transport section and downstream discharge belts in a withdrawal section of the discharge station, the method being characterized in that the withdrawal belts are at least temporarily operated at a higher speed than the flap or conveyor belts.
  • the carton blanks are literally pulled out of the conveyor belts, thereby automatically increasing the distance between successive carton blanks as needed. Due to the greater distance between the individual carton blanks, a longer reaction time is made available even at a relatively high conveying speed, within which the rejection of defective carton blanks can be carried out. In this way, higher overall processing speeds can be used, or even longer and stiffer carton blanks can be safely led out of the process if errors are found.
  • a distance or a gap between successive carton blanks is calculated, and an increase in speed of the take-off belts is controlled as a function of the calculated gap.
  • the position detecting means detect the beginning and / or the end of the conveyed cardboard blanks, and depending on the error detection and a pivoting of the flap portion of the conveyor belts for discharging defective carton blanks is controlled.
  • Non-contact optical sensors with which the beginning and the end of the respective carton blanks can be determined precisely can serve as position detection means. Other types of sensors can also be used. This avoids that an early adjustment of the hinged conveyor belts takes place. This serves to ensure safe removal of all defective carton blanks. The ejection process is made possible in a relatively short time, so that even at high process speeds all defective carton blanks can be safely led out of the process.
