Definitions

  • the invention relates to a device for conveying scaly objects, in particular flat folded cartons, with a feeding device, with which the flat objects are supplied in a scaly form a conveyor.
  • a generic device for packing flat folded cartons in cartons is known in which the conveyor has a lowering rail and pivoting rail, each with a circulating belt. Between the belts, the shingled supplied cartons are conveyed in cartons as a transport container.
  • the lowering rail serves as an abutment which cooperates with the swivel rail at the delivery point in order to guide the folding boxes as far as possible into their final position in the transport container.
  • a downwardly projecting and longitudinally displaceable shift rail is attached to the substantially vertically movable lowering rail, which actuates a switch as soon as it touches down on the bottom of the transport container.
  • the lowering of the lowering and pivoting rail is stopped by means of a hydraulic drive at a defined distance from the bottom of the transport container.
  • An adjustment of the distance for example, to adapt to different Faltschachtelformate, is possible only via a mechanical access in the structure of the conveyor.
  • the DE-PS 28 25 648 also describes a device for introducing Faltschachtelzu motherboarden in transport containers, in which the blanks are passed between an upper belt and a lower belt of a conveyor.
  • the Under- and upper belts of the conveyor are driven by independent, unspecified drives.
  • Another packing device of this type is described in DE-AS 22 61 416.

  • This offers the advantage that depending on the weight of the resting boxes sets a different conveying force.
  • the conveying force is very low in the area of the jam line, while it is large at the beginning of the feeder, since there the boxes are scaly with greater distance from each other resting on the belt.
  • Another advantage results from the fact that the conveyor belt can convey continuously, which greatly facilitates the control of the feeder.
  • the pressure in the pressure hose is adjustable via a control valve. The conveying effect of the belt is thus controllable in dependence on the weight of the cartons.
  • a packing device is used for wrapping flat folded cartons 1 in outer cartons 2. It is located behind a Faltschachtelklebemaschine in which folding cartons are made.

  • Each promotional strand is supported on its back by spring elements 86.
  • Each longitudinal beam 84 is transversely adjustable by means of a linear drive, so that the two belt conveyors 16, 17 can be moved toward and away from each other to keep a carton 2 clamped.
  • Each conveyor belt 80, 81 of a belt conveyor 16, 17 is connected to a rotary drive 85, which drives one of the deflection rollers 83 via an angular gear.
  • the two-part form of each belt conveyor 16, 17 has the advantage that there are two independent conveyors in a row. This makes it possible to supply empty cartons with the two first conveyor belt 80, while filled cartons 2 are transported away with the second conveyor belt 81.
  • drives 85 for the conveyor belt 80, 81 electrical servomotors are preferably used, which allow precise control of the feed of a carton 2 during filling.
  • the structure of the conveyor 9 is shown in more detail in Figure 6. It has at its end a lowerable pivot rail 32 and a lowering rail 22, which can be lowered in a substantially vertical movement to the bottom 23 of a carton 2.
  • a sensor 24 is attached, which determines the distance between the vertically lower end of the lowering rail 22 and the bottom 23 of the outer carton 2 without contact.
  • an ultrasonic sensor is used as the sensor 24, which is attached via an angle plate 26 on the support structure of the conveyor 9. The sensor 24 makes it possible to automatically adjust the distance of the end of the lowering rail 22 from the bottom 23 of the outer carton 2 or from a position of boxes 1 already in the carton.

  • the axis of rotation of each roller 43 is inclined at an acute angle to the vertical in the conveying direction.
  • the longitudinal members 44 with the rollers 43 attached thereto are arranged transversely adjustable so that the rollers each guide a carton 2 on the side walls in the lower area.
  • the inclination of the rollers 43 causes the outer carton 2 conveyed by the belt 40 to be pressed onto the belt 40.
  • the increased contact pressure improves the promotion and at the same time prevents the bottom flaps of the carton open and push it upwards. Since the bottom flaps of the outer carton 2 are pressed flat on the belt 40, the distance sensor 24 is the flat bottom of the carton 2 as a defined reference surface for the distance determination available.
  • At least one of the longitudinal members 44 is mounted transversely adjustable, so that the distance between the two longitudinal members 44 can be set to different outer carton widths.

If the cartons 2 with multiple layers of boxes 1 one above the other and / or with multiple rows of Boxes are to be filled next to each other, takes an operator, not yet completely filled cartons of the roller conveyor 19, carries them back to the belt conveyor 14 and sets it there for the next filling operation again. Completely filled outer cartons are removed.
  • This simple embodiment has the advantage that the packing device is not wider than the folding box gluing machine arranged in front of it. It can therefore be used even in very tight spaces. If there is sufficient space in the width, this can be used for the automatic return transport, as shown in the embodiment of Figure 2.

  • the stowage and transfer device 50 has the task to collect a certain number of boxes 1 and to hand over the belt 27, 29 of the conveyor 3 in a flake shape with a preset degree of overlap. For this purpose, the boxes 1 are continuously conveyed by the belts 4 of the feed device 3 against the beginning of the conveyor 9.
  • the storage and transfer device 50 consists of a Schupprolle 51, which is arranged at the lower beginning of the conveyor 9 and at the same time forms the inlet-side guide roller of the lower conveyor belt 29.

  • the circulating conveyor belt 29 is guided to the subsequent, the conveying path of the conveyor 9 limiting pulley 52 in a loop, so that the conveyor line is interrupted below a small piece.
  • the position of the loading roller 51 relative to the deflection roller 52 determines the degree of overlap with which the boxes 1 are withdrawn from the feeder 3. Therefore, the Schupprolle 51 is mounted in a pivotable bearing part 53, so that the Schuppungsgrad on the position of the Schupprolle 51 can be set to the desired value.
  • a down-holder strip 54 extending against the conveying direction of the boxes 1 is fastened to the conveyor 9.
  • the hold-down bar 54 has the task of keeping upright stacking boxes 1 at its upper edge. Your distance from the belt 4 of the feeder 3 is set to the box width. It forms together with the ends of the belt 4 a jam section 55, as shown in Figure 1 can be seen. Since with the number of accumulating in the jam section 55 boxes 1, these are increasingly vertical, the minimum distance between the upper edges of the boxes 1 of the hold-down bar 54 is a measure of the number of jamming boxes 1.
  • an electromechanical sensor is integrated, which determines the height of the box package between the belt 4 and the hold-down bar 54 and thus the number of accumulating boxes 1.
  • the hold-down bar 54 At the end of the hold-down bar 54 is a against the lower conveyor belt 29 extending elastic Schuppfinger 56 is attached.

  • the positions of the hold-down bar 54 with the Schuppfinger 56 and the Schupprolle 51 are coupled to each other adjustable, as shown in Figures 6 and 8.
  • This has the advantage that a conversion of the storage and transfer device 50 to another box format can be carried out very quickly and without much effort.
  • the lever mechanism formed by the bearing members 53, 57 and the levers 58 is designed so that the movements of the hold-down bar 54 are coupled to the Schuppfinger 56 and the Schupprolle 51 performed to the extent necessary, so that in a format adjustment each part assumes its new position , Thus, the position of the Schupprolle 51 can be additionally adjusted relative, this is additionally attached to its bearing part 53 adjustable.
  • the joint coupled adjustment of the elements offers the possibility to automate the adjustment. Instead of the handwheel 60 then an adjustment is used, which moves the adjusting rod 59.
  • the feed device 3 shown in more detail in FIG. 9 contains, as conveying elements, belts 4 which extend into the accumulation section 55 and thus also convey against pent-up cartons 1. They are advantageously designed so that the conveying action of the conveyor belt 4 depends on the contact pressure of the boxes 1 and this dependence is additionally adjustable.
  • each conveyor belt 4 as a sectional drawing shown between two upper guide rails 70 and rests on a pressurizable air pressure hose 71 on. Between the pressure hose 71 and the conveyor belt 4, a thin, deformable plate 72 is arranged, over which the conveyor belt 4 can slide with little friction.

Laterally, the pressure hose 71 of incompressible cheeks and on its underside, the pressure hose 71 is also supported by an incompressible component. The pressure hose 71 thus acts primarily in the direction of the conveyor belt 4.
  • the belt 4 thus acts on the undersides of the boxes 1 and promotes them further. Increases the weight of the cartons 1, the conveyor belt 4 is pressed down against the force of the pressure hose 71. It moves relative to the surfaces of the guide rails 70 down until they lie in a plane with the surface of the belt 4. In this position, the boxes rest on the surfaces of the rails 70 and are no longer conveyed by the belt 4. Over the conveyor length of the belt 4 can thus adjust depending on the weight of the resting boxes 1, a different conveying force. The conveying force is very low in the area of the accumulation section 55, while it is large at the beginning of the feed device 3, since there the cartons 1 are scaly with greater distance from each other resting on the belt 4.
  • each pressure hose 71 is connected via lines 73 and a control valve 74 to a compressed air source 70.
  • the two guide rails 70 and the pressure hose 71 with the overlying conveyor belt 4 each extend over the entire conveying path of the feed device 3. They are arranged between two cheek-shaped side parts 75, which are screwed together and are mounted transversely adjustable on spindles 76.
