Definitions

  • the invention relates to an arc-shaped product processing machine, in particular a folder, with at least two product paths formed by branching belt sections which can be alternately released or closed by means of a switch which is arranged on the branch and has a movable flap.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, therefore solves the problem of designing an arrangement of the type mentioned at the outset, avoiding the disadvantages of the arrangements used hitherto, in such a way that the switch can be actuated as desired and can be left in one position or the other for any length of time can be and that operational interruptions to switch the switch are avoided.
  • an actuator is provided for driving the switch flap, which is actuatable by means of a control device, which in turn can be activated independently of the machine operation by means of a corresponding switchover pulse, and whose control motor-side control output is provided by one of the flap upstream, the product or gap sequence sensor can be released at the moment when the flap is exposed when a gap passes between two successive products.
  • a particularly advantageous development of the superordinate measures can be characterized by an electromagnetic servomotor for flap actuation, the flap expediently having an actuating arm arranged laterally, which is advantageously connected to the armature of oppositely arranged lifting magnets.
  • These measures are associated with the advantage that the switching and playing times can be determined exactly. At the same time, the required short switching times can be easily achieved.
  • a voltage which is above their nominal voltage, preferably twice the nominal voltage can be applied to the lifting magnets in a very particularly expedient manner. This advantageously results in temporary overexcitation of the solenoids and thus leads to a significant reduction in the lifting time. Since this also results in a shortening of the duty cycle, there is no fear of damage to the solenoids, so that a long life and high functional reliability are guaranteed.
  • the product path indicated by the arrow 1 in FIG. 1 is branched in the region of a guide roller 2 into two further product paths, identified here by the arrows 3 and 4.
  • the lower run 5 of the belt section forming the product path 1, which continues in the direction of the product path 3, is guided around the guide roller 2 by about 90 ° and thereby lifts off the upper run 6 of the belt path forming the product path 1, which practically only affects the guide roller 2 and without any significant Change of direction continues in the direction of product path 4.
  • Sub-run 5, which continues in the direction of product path 3 is assigned a strip 8 guided around a corresponding strip roller 7 following the branching point.
  • the upper run 6 which continues in the direction of the product path 4 acts to form a complete belt section consisting of upper and lower run following the branching point with a corresponding belt roller 9 around band 10 together.
  • the belt sections forming the different product paths each consist in a manner known per se of several individual belts arranged next to one another at a certain distance.
  • a wedge is formed by the whole 11 designated flap formed switch.
  • This flap 11 consists of a plurality of tongues 12 which are arranged next to one another and extend counter to the running direction and which engage in a rake-like manner between the individual bands of lower run 5 and upper run 6.
  • the side by side tongues 12 are mounted on a continuous shaft 13 which is pivotally mounted in the machine frame, so that the tongues 12 from the position drawn with solid lines, in which the product path 3 is blocked, into the position drawn with dash-dotted lines, in which the product path 4 is blocked, can be brought and vice versa.
  • the tongues 12 are wedge-shaped, the flank interacting with the lower run 5 forming a guide surface 15 parallel to the rounding of the guide roll 2 receiving the lower run 5 and the flank interacting with the upper run 6 forming a guide surface 16 approximately parallel thereto.
  • the shaft 13 receiving the tongues 12 is provided with a lateral arm 17 which is connected to a servomotor which produces a reciprocating movement.
  • the arm 17 is connected to the armature 18 of opposing, opposing lifting magnets 19 for accomplishing an electromagnetic drive. This advantageously avoids reversing the lifting magnets.
  • the solenoids 19 are simply overexcited during the setting process. This is achieved in that the solenoids 19 are applied to a voltage above their nominal voltage, in this case approximately twice the nominal voltage, during the switching process. In order to be able to hold the flap 11 in one position for any length of time, however, this overexcitation is reduced again immediately after the switchover and a voltage is applied which enables a long duty cycle.
  • an electronic control device designated as a whole by 20, is provided, which ensures that exact switching times are observed.
  • the control device 20 can be activated at any time by a pulse generator, here by a manually operated push button 21, etc.
  • the flap 11 can only be switched over when the tongues 12 are exposed during the passage of a product gap.
  • a sensor 22 is provided upstream of the flap 11 and receives the product or gap sequence in the area of the product path 1, the message of which is processed by the control device 20 in such a way, for example by integrating the path up to the flap 12, that its solenoid side Control output 23 is only released when the flap 11 is passed by a so-called product gap.
  • the sensor 22 can expediently be designed as an inductive pickup.
  • the switch formed by the flap 11 is expediently arranged in the belt section leading away from the last folding unit formed here by the folding jaw cylinder 24 and the folding blade cylinder 25.
  • the sensor 22 of the control device 20 can advantageously be arranged directly on the jaw cylinder 24, on which a fixed product stop is present.
  • the belt sections leading away from the switch formed by the flap 11 and forming the product paths 3 and 4 both lead to a delivery station, which is indicated here by the paddle wheels 26 and 27, which deposit a scale-like product stream on respectively assigned conveyor belts 28 and 29.
  • the paddle wheel 26 serving the product path 3 is intended to serve, for example, as a good delivery, the paddle wheel 27 serving the product path 4 as a waste delivery or vice versa.
  • the flap 11 is, for example, in the dash-dotted line in the figures ten lines indicated position in which the paddle wheel 26 forming the crop delivery is applied.
  • the switch button 21 is pressed, whereby the control device 20 is activated.
  • the sensor 22 reports a product gap or a size from which the control device 20 determines a size corresponding to a product gap in the area of the flap 11, the changeover command is sent to the lifting magnets 19.
  • the changeover process takes place so quickly that the tongues 12 the flap 11 exactly dive through the relevant product gap.
  • the flap 11 jumps into the position shown in the illustrated embodiment with solid lines.
  • the flap 11 is now held in this position until all waste copies have been removed from the product stream.
  • the switch to normal operation is also carried out by pressing a button.
  • the switch according to the invention can advantageously be used wherever it is important to redirect a product stream for an indefinite time. For example, it would be readily possible, in the event of malfunctions in the product path leading to product delivery, to guide the product stream via the other product path until the fault has been eliminated.
  • control device 20 is activated manually. To achieve a fully automatic process, however, it would also be readily possible to provide appropriate monitoring devices which report a roll change etc. to the control device 20, which then activates the solenoids 19, preferably with a corresponding delay.
