Definitions

  • the invention relates to a device for stacking coming from a folding box gluing machine, flat folded folding boxes with the folding boxes attacking the top and bottom of the belt, the speed of which is greater than the transport speed of the gluing machine, in the direction of transport behind and above the lower belt and under the forming Stack
  • the front deflection roller is arranged at least one suit belt, through which the respectively arriving folding box is pulled up to a stop under a stack which is formed and which is continued after formation of a finished stack by at least one stack feed element.
  • DE-C-1 959 174 Devices of the type described above are known from DE-C-1 959 174. With them, the arriving folding box is pulled under a forming stack, the folding boxes of which lie with their front edges against stops. By using a stop running across the entire width of the machine, only folding boxes with a substantially straight front edge can be processed with the device known from DE-C-1 959 174, the finished stack also having to be lifted when or through the stack feed element onto the subsequent conveyors to be transferred. In addition to a restriction with regard to the shape of the folding boxes to be processed, the known device therefore has the disadvantage of a high expenditure of energy and time, since during the transfer of a finished stack to the subsequent conveyor it must be ensured that there is no inflow of folding boxes to be stacked.
  • the invention is based on the object, while avoiding the disadvantages of the known prior art, to further develop a device of the type described at the outset such that a wide variety of folding boxes, in particular folding boxes with a leading edge deviating from a straight line, can be stacked continuously without the finished stack in each case raised before transfer to the subsequent conveyor and the supply of folding box blanks must be interrupted during the transfer process.
  • folding boxes with lids and with rags resting on the surface should also be able to be stacked reliably.
  • the solution to this problem by the invention is characterized in that the folding boxes rest with their front corners on laterally arranged stop angles, that the stop angles can be moved out of the holding position after formation of a finished stack and that the stack feed elements feed the stack to a pair of transport and press belts and that a single stop for each arriving folding box is arranged below each stop angle, which can be moved out of its locking position regardless of the stop angle at the start of the stack transfer and can be transferred back to its locking position immediately after the stack leading edge has been transferred to the transport and press belt.
  • a stacking device is created with which arbitrarily designed folding boxes, which come from a folding box gluing machine and are lying flat together, can be stacked into stacks of a predetermined number.
  • Each folding box coming from the folding box gluing machine is replaced by the ones attacking on its top and bottom Pulling on the straps, the speed of which is greater than the transport speed of the gluing machine, and guided under a forming stack.
  • the deflection roller of the tightening belt arranged behind and below the lower feed belt in the transport direction of the incoming folding box ensures that the stack is lifted with each new folding box, because when it hits the circumference of the front deflection roller it is lifted and pulled under the stack. Since the suit belt rotates continuously, at the same time it causes a constant slight pulling forward of all the folding boxes of the stack, so that these lie firmly against the temporally arranged stop angles with their leading edges in the corner area.
  • stop angles can be moved out of their holding position, so that they release the transport path for this stack after the formation of a finished stack.
  • the finished stack is raised slightly by stack feed elements and fed to a pair of transport and press belts, which is located behind the stacking point in the transport direction. Between these transport belts and press belts, the individual stacks are stored in a kind of intermediate storage and continuously conveyed out of the device.
  • each incoming folding box is held exactly in accordance with the folding boxes of the stack above, a single stop is arranged below each stop angle. This is independent of the stop angle at the start of the stack transfer from its locked position movable so that it does not hinder a transfer of the finished stack to the transport and press belt pair, in particular does not hold the bottom folding box. However, as soon as the bottom folding box has passed the single stop with its front edge, this is brought back into its blocking position, so that a folding box brought in by the intake belts is reliably held in the stacking position, even if the stack is not yet completely between the transport and pressing belts located.
  • the device can be aligned without difficulty to any plan or cross-section of a folding box.
  • the device according to the invention can thus also reliably stack complicated folding boxes that are not stackable with the known devices.
  • the stack feed elements are formed by two turntables, each of which has a semicircular support surface which is twisted in the manner of a half-worm gear with a vertically standing driving rod and is rotatably mounted about a vertical axis lying laterally outside the transport path for the folding boxes .
  • the finished stack is raised slightly by rotating the semicircular turntable twisted in the manner of a half-worm gear by 180 °.
  • the upper transport and press belt preferably has a funnel-shaped inlet on its front. After the stack has been handed over to the transport and press belts, the turntable returns to its starting position, in which both the semicircular contact surface and the carrier bar lie outside the transport path for the folding boxes.
  • the leg serving as a stop for the front edge of the stacked folding boxes of the stop angle is pivotally mounted about the apex of the respective angle.
  • the leg of which lies laterally and parallel to the transport direction is rigid.
  • the pivoting of the front leg, which lies against the front edge of the stacked folding boxes, can take place, for example, by means of a compressed air cylinder.
  • Compressed air cylinders of this type can also be arranged to actuate the individual stops, which according to a further feature of the invention can be designed as a Z-shaped flap in vertical section, which is pivotably mounted in a horizontal axis.
  • the invention finally proposes to form this upper edge of the flap by a freely rotatable roller.
  • the proposal according to the invention results in a device for stacking folding boxes coming from a folding box gluing machine, which can be used universally, has a simple construction and works even at high speeds with great functional reliability because, apart from continuously rotating belts, only a few controlled movements take place, which also run with the necessary precision within a sufficiently dimensioned period by the division according to the invention.
  • a machine frame 1 can be seen, on each of which two lower feed belts 2 and two upper feed belts 3 are mounted by means of their deflection rollers 2a and 3a.
  • These feed belts 2 and 3 which run parallel to one another in accordance with the plan view in FIG. 3, engage on the underside or on the top of flat-folded folding boxes F which come from a folding-box gluing machine, not shown. To get a proper deduction of this. To ensure folding boxes F, the speed of the feed belts 2 and 3 is greater than the transport speed of the Faitbox gluing machine.
  • each folding box F is supplied with two pull belts 4, which likewise run on deflection rollers 4a and 4b at a speed corresponding to the feed belts 2 and 3.
  • the front deflecting roller 4a is arranged behind and above the lower feed belt 2 in the transport direction of the folding boxes F, so that they the incoming carton F slightly increases.
  • the upper run of the suit straps 4 drops slightly towards the rear in that the diameter of the rear deflection roller 4b is smaller than that of the front deflection roller 4a.
  • the suit straps 4 serve to form a stack in cooperation with stops to be described in more detail and, on the other hand, to constantly pull the folding boxes F of this stack against these stops by continuously pulling on the bottom folding box F as a result of the continuously rotating suit straps 4 is exercised on the attacks.
  • the stops for forming the stack consist of two stop angles 5 arranged laterally corresponding to the width of the folding boxes F and two individual stops 6 arranged below the stop angles 5.
  • the stop angles 5 have a rectangular cross section with a fixed leg 5a running parallel to the transport direction of the folding boxes F. serves as a lateral guide for the respective front corner of the folding boxes F and can be adjusted to the respective width of the front edge of the folding box by laterally adjusting the stop angle 5.
  • the leg 5b of the stop bracket 5, which runs parallel to the front edge of the folding boxes F, serves to abut the folding box front edges and can be pivoted forward about the apex of the stop bracket 5, so that the folding boxes F merged into a stack can be released at a suitable moment for further transport.
  • the pivoting of the front leg 5b of the stop bracket 5 is in each case carried out by a pressure medium cylinder 7, which acts on the movable leg 5b by means of a piston rod 7a.
  • the folding box F delivered by the feed belts 2 and 3 meets with its front edge according to FIGS. 1 and 2 on the pulling belt 4 guided over the front deflection roller 4a and is raised slightly by it.
  • This lifting is supported in the illustrated embodiment by two rollers 8, which can be seen in the top view in FIG. 3.
  • These rollers 8 lie between the tightening straps 4 and have a circumference which corresponds to the shape of the tightening strap 4 guided over the front deflection roller 4a.
  • Each arriving folding box F is pulled with its front edge by the straps 4 against the two individual stops 6, as can best be seen in FIGS. 1 and 2.
  • These individual stops 6 correspond to the legs 5b of the stop angle 5, which begin only above the lowest folding box F of the stack being formed. This means that upon arrival each folding box F runs against the individual stops 6, but after being lifted by a new folding box F it is held in the position assumed by the stop angles 5.
  • the individual stops 6 are formed in a Z-shaped vertical section and can be pivoted counterclockwise about a horizontal axis 6a by means of the piston rod 9a of a pressure medium cylinder 9. Swiveling the front legs 5b of the two stop angles 5 and the individual stops 6 thus clears the way for further transport of the stack formed in front of the stops 5 and 6.
  • two hold-down devices 10 are arranged, which can be seen in the side view in FIGS. 1 and 2 and in the top view in FIG. 3.
  • a microswitch or photocell is used to determine when the predetermined number of folding boxes F has been reached, so that the stack formation is complete and the stack can be transported further.
  • stack feed elements are provided which are formed by two turntables 11 in the exemplary embodiment shown.
  • This turntable 11 have the shape of a semicircle and are attached to an axis 11 a, which is mounted vertically outside the transport path for the folding boxes F.
  • the turntables 11 are twisted in the manner of a half-worm gear, so that when they rotate, which leads them with their contact surface under the bottom folding box F of the stack, they also cause this stack to be lifted, due to their twisting in the manner of half Worm or thread.
  • each turntable 11 has a drive rod 11b which comes to rest when the turntable 11 is rotated at the rear edge of the stacked folding boxes F and moves the lifted stack further in the transport direction during the further rotary movement.
  • the movable legs 5b, the stop angle 5 and the individual stops 6 were moved out of their locked position by means of the pressure medium cylinders 7 and 9.
  • the stack formed in cooperation with the stop angles 5 and individual stops 6 can in this way be fed specifically to a downstream transport device which, in the exemplary embodiment shown, consists of three transport belts 12 for supporting the stack and three press belts 13 which are above the transport belts 12 at a predetermined distance are arranged and press on the transferred stack from above to prevent this stack from disintegrating.
  • Each transport belt 12 or press belt 13 is guided over a plurality of deflection rollers 12a or 13a.
  • the front deflection rollers 13a of the press belt 13 are arranged according to FIGS. 1 and 2 in such a way that a funnel-like Liche entry slope for the stack results.
  • the rear deflection rollers 12a and 13a of the transport belts 12 and press belts 13 are arranged on a movable bridge holder 14, with the aid of which the removal of the stack lying between the transport belts 12 and 13 can be adapted to the subsequent machine, which is preferably a manual one is operable or fully automatic bundling machine.
  • each individual stop 6 is formed by a freely rotatable roller 15, which is shown in FIGS 4 and 5 can be seen.
  • stacking thus always includes a counting process with respect to the folding boxes F to be combined, whereby it is of course possible to change the number of folding boxes F combined into a stack.
