Definitions

  • the invention relates to a device for simultaneous, three-sided trimming of products according to the preamble of claim 1 and a method for the controlled transport of products through the cutting stations of such a device.
  • the collected and stapled products are cut on saddle stitchers in a device for three-sided trimming, such as a trimmer. This takes place in the cutting stations for the leading edge trimming and the head and foot trimming by moving the upper knife against fixed lower knife or cutting bars.
  • trimmer From the EP 1 152 310 A1 such a trimmer is known.
  • the trimmer has a common upper knife bridge, which can be operated in a lifting movement via a servomotor.
  • the top knives for the leading edge trim and for the head and foot trim are attached to the top knife bridge.
  • the leading edge trimming takes place in a first cutting station and the head and foot trimming in a second cutting station.
  • the trimmer In order to transport the products into and out of the cutting stations, the trimmer has a transport device for the products.
  • the three-sided trimming is carried out in individual steps.
  • the transport system transports the product to the first cutting station and brings the product to a standstill in the exact position. Then the leading edge is trimmed.
  • the product is then transported by the transport system to a second cutting station and brought to a standstill in the exact position. Then the head and foot are trimmed. The three-sided trimmed product is then transported to the display.
  • That from the EP 1 152 310 A1 known transport system consists of pairs of belts on the head and foot, between which the product is frictionally clamped. The belt pairs are driven by an independent drive, for example a servo motor, via continuous drive shafts.
  • a downstream transport or processing device such as a delivery belt or a compensating stacker for stacking the products
  • a downstream transport or processing device such as a delivery belt or a compensating stacker for stacking the products
  • speed differences to the transport system of the Trimmers on. If the speed of the products exceeds the speed of the transport system of the downstream processing device, the products are braked in an uncontrolled manner and the product thus deviates in the transport direction.
  • positional deviations depend, among other things, on the product format and the machine speed and can lead to malfunctions in the downstream transport or processing device. Such malfunctions can occur, for example, when two consecutive products are fed to the compensating stacker with insufficient spacing and thereby cause a jam
  • the object of the present invention is to create a device which avoids the disadvantages of the prior art and ensures a controlled transport of the products.
  • An embodiment according to the invention of a device for simultaneous three-sided trimming of products has several cutting stations. Furthermore, the device has a common upper knife bridge which extends through the cutting stations. The upper knife bridge can be operated in a lifting movement via a first drive. At least the knives for leading edge trimming and for head and foot trimming are attached to the upper knife bridge.
  • the products are transported through the cutting stations of the device by means of a transport device with pairs of belts on the head and foot.
  • the transport device is driven by at least one second drive.
  • the drives for the lifting device and the transport device are each designed as independent drives that are independent of one another and are connected to one another via a control device.
  • the device In the transport direction of the products, downstream of the transport device, the device has a further delivery transport device.
  • the delivery transport device is from a Another independent, independent drive is driven, which is connected to the other independent drives of the device via a control device.
  • the delivery transport device has a servo drive, a toothed belt drive train and rollers for transporting the products.
  • This constellation enables particularly simple transfer and speed adjustment when transporting the products.
  • the independent drives are designed as servomotors which are connected to one another via corresponding control units for the exchange of data and / or control signals.
  • a central control for these individual drives is also advantageous.
  • FIG Figure 1A A representative example of a cutting device 19 for edge trimming with separate drive devices according to the prior art is shown in FIG Figure 1A shown.
  • a first drive motor 1 realizes the movement of the upper knife bridge 2 to which the upper knife are attached. The direction of product travel is indicated by arrows T.
  • a second drive motor 4 drives the belts 7, 8 of the transport system 9 via a first and second continuous drive shaft 5, 6.
  • Control units 10, 11 are provided for both drive motors 1, 4 and can communicate with one another by means of a connection for the exchange of data and / or control signals 12. Furthermore, the connection 12 can also lead to a central machine control unit 18.
  • the essential elements of the drives realizing the two motion sequences are in the Figure 1B recognizable.
  • the first drive motor 1 implements the vertical, inharmonious oscillating movement of the upper knife bridge 2 by means of the toothed belt 15, the toothed belt pulley 16 and the gearbox 17.
  • the upper knives 3 are pressed against the lower knife 13 during the cutting process.
  • the second drive motor 4 drives by means of a mechanical gear 14 the shafts 5, 6, so that the belts 7, 8 of the transport system are moved.
  • the arrows T indicate the product direction.
  • FIG. 2 and 3 a cutting device 20 according to the invention is shown, wherein in Figure 3 For the sake of clarity, only the top-side transport device is shown and the control units and the connections have been omitted.
  • the cutting device 20 has an upper knife bridge 25, which is set in lifting movements by a drive motor 21.
  • the upper knife bridge 25 extends through all cutting stations, in the present example there are three: the station 26 for the front edge trimming, the station 27 for the head and foot trimming and a further processing station 28 for special punchings or for blank separation.
  • Corresponding upper cutters 29, 30, 31, 32 are attached to the upper cutter bridge, which are moved against lower cutter 33 and thus carry out the edge trimming or special punching or blank separation of the product 40.
  • the product 40 is transported by a transport device 34 through the individual cutting stations 26, 27, 28 of the device 20.
  • the transport device 34 has transport belt pairs 37, 38 on the head side 35, 36 and on the foot side, between which the product 40 is clamped.
  • the head-side transport belt pairs 35, 36 are driven by an independent drive motor 23 and the foot-side transport belt pairs are driven by an independent drive motor 22.
  • the device 20 has a delivery transport device 39, which is connected downstream of the transport device 34.
  • the delivery transport device 39 also has an independent, independent drive.
  • the individual independent drive motors 21, 22, 23, 24 are coupled to one another via their associated control units 47, 48, 49, 52 via a connection 50 for the exchange of data and / or control signals. Furthermore, they can also be connected to the central machine control 51. In this way it is possible to apply a defined movement profile to the respective drive motors 22, 23 and 24 and thus to the product 40 on the basis of special, changeable movement profiles of the drives can be transported in a fully controlled manner without deviations in position.
  • the transport direction of the products 40, 40 ', 40 ′′ is shown by the arrows T.
  • the transport device 34 extends through three cutting stations. In the first station, the front edge is trimmed by means of the upper knife 29 and the lower knife 33 Head and foot trimming by means of top knives 31, 30 and bottom knife 33. In the third station, blank separation takes place by means of separating knife 32 and bottom knife 33. In the second or third station, special punchings can also be made using appropriate punching tools 41. The product is stationary during the cutting process 40. After the respective cutting process, the product 40 is transported to the next cutting station.
  • the products are transported by means of two pairs of transport belts 35, 36, 37, 38, which face each other in pairs and clamp the product in a force-fit manner at the top and bottom.
  • the product 40 is accelerated by the transport device 34 within the device 20, transported in the correct position into the respective cutting station and then braked to a standstill. This process is repeated for further processing steps and finally for transporting the product out of the device 20 to a transport device, a processing device or display, which is located downstream of the device 20.
  • the device 20 has a delivery transport device 39 downstream of the transport device 34. This is formed from a servomotor 24, a toothed belt drive train 42 and the rollers 43, 44, 45, 46 for transporting the products 40 or individual copies 40 ', 40 ".
  • Figure 5 shows an example of a possible movement profile of the transport device 34 during an entire work cycle (0-360 °) of the cutting device. Shown in Figure 5 is in the upper diagram the path of a cam in degrees of rotation angle, in the middle diagram the first derivative as normalized speed (ds / dPhi) and in the lower diagram the second derivative as normalized acceleration (dv / dPhi), each over 0 ° - 360 ° ( x-axis), which correspond to a machine cycle.
  • the bottom dead center of the upper knife bridge at 0 ° and 360 ° is designated by 100, 105. At this point the cutting process is complete but the product is not yet free. As a result, the transport device is not yet moving. At point 101 the product is released and transport can begin.
  • the path of the cam disk is still zero at point 101; likewise the speed.
  • the acceleration of the conveyor belt starts at point 101, as shown in the diagram below Figure 5 to recognize.
  • the conveyor belts are accelerated up to point 102 (approx. 164 °).
  • the cam has covered a distance of around 130 degrees of rotation and the conveyor belts move at a standardized speed of 3.2. No further acceleration takes place up to point 103, so that the conveyor belts continue to move at the same speed.
  • From point 103 to 104 the product is placed in the next cutting station or a new product is placed in the first cutting station.
  • the conveyor belts are braked accordingly to a standstill. From point 104 to 105 the belts stand still.
  • the product is pressed off by means of press beams (not shown in greater detail) and the upper knife bridge is lowered to the bottom dead center and thus the edge of the product 40 is trimmed.
  • FIG. 5 the basic speed 210 of the delivery transport device 39 is shown.
  • the points of intersection 201, 204 with the speed profile 211 of the transport device 34 each result in the starting point for the acceleration or deceleration of the delivery transport device 39.
  • Figure 6 shows a Figure 5 based possible movement profile of the display transport device 39.
  • the display transport device moves at a constant base speed 210.
  • the display transport device 39 is accelerated until both transport devices 34, 39 then move at the same speed.
  • the delivery transport device 39 is braked down to the base speed 210. After the delivery transport device 39 has taken over the product 40, it can be adapted to the speed (not shown) of a subsequent processing station.
