Definitions

  • the invention relates to a machine for producing two-part objects, the parts of which are connected to one another in a defined spatial assignment, for example a folding box blank and a window blank made of transparent PVC film.
  • Machines for the production of boxes from box blanks are generally known, they are usually designed as a production line in which the individual operations, such as singling, punching, creasing, folding or erecting, gluing and depositing in their logical sequence in individual, especially for this established stations can be made.
  • the individual operations such as singling, punching, creasing, folding or erecting, gluing and depositing in their logical sequence in individual, especially for this established stations can be made.
  • a manual processing step must generally be switched into this production line with the well-known disadvantages with regard to the production speed and the cost.
  • the object of the invention is therefore to provide a machine with which this process, that is to say the connection of different components to form a two-part object, can be automated in a simple manner, in particular can be adapted to the cycle of the production line.
  • the machine according to the invention achieves this object by separating the first parts, conveying them essentially perpendicular to the conveying direction of the second parts and connecting them to the second parts, the machine having horizontally adjustable conveyor belts for this purpose, which transport the second parts to a fixed point, at least one magazine that can be adjusted to the format of the first parts, that stores this, a horizontal conveyor track for the first parts between the magazine and the production line that runs over this fixed point, and at least one transport carriage that runs on the conveyor track and removes the first parts from the The magazine is removed and placed in an adjustable relation to the fixed point on a second part which is conveyed there and positioned by means of the conveyor belts.
  • the basic idea of the invention is therefore to feed the two parts, for example a cardboard blank and a window blank made of PVC foil, in vertical paths and to connect them to one another in an adjustable relation to a fixed point.
  • the conveyor track includes at least one guide tube which extends at least from above the magazine to above the fixed point on which at least one transport carriage is slidably mounted.
  • This solution enables simple mounting and mounting of the transport carriage and easy movement of the transport carriage on the guide tube between the two end positions, ie the magazine and the fixed point.
  • the transport carriage is optionally connected to a device for generating negative or positive pressure, and has a downward facing counter plate with a plurality of integrated, downward facing pressure outlet openings for the window blanks.
  • the transport carriage can "grasp” the window cuts (by suction using negative pressure) or push them off again via fixed point F (above the associated cardboard cut) (using positive pressure).
  • An advantageous embodiment provides that two guide tubes extend on both sides of the fixed point to one magazine each and that two transport slides are provided which are controlled in a clocked manner, such that one transport sled is located above one of the two magazines when the other transport sled is above the Fixed point is positioned.
  • each magazine contains a lifting table spring-loaded from below, on which a number of window blanks is stored, in such a way that the respective upper window blank is pressed against a height-fixed stop, up to which the counterplate, which is at that time pressurized the transport carriage can be lowered by means of cylinder guides.
  • the stop thus also creates a defined path that the counterplate of the transport carriage has to travel downwards until it contacts the upper window cut and then sucks in by means of negative pressure and lifts it off the remaining stack of window cuts.
  • At least three vertical tubes are slidably mounted on a horizontally mounted base plate, between which the lifting table slides and that these tubes are slidable in elongated hole guides in the base plate, which extend radially from a center of the base plate extend outwards.
  • the base plate can be horizontally adjusted on all sides in an outer frame part for fine positioning, so that the positioning of the window blanks can be carried out with the greatest accuracy.
  • compressed air nozzles are arranged at the level of the stop for the upper window cut, which counteract a compressed air flow directed in the surface of the upper window cut to support the separation when the counterplate under pressure is placed on it.
  • This stream of compressed air causes a Vacuum above the top window blank, a solution of this top window blank from the stack below, so that this "prepared" window blank can then be more easily separated from the stack underneath by the vacuum-applied counter plate of the transport carriage.
  • the figures first show a section of a production line 20 for processing box blanks, for example the carton blank 10 shown on the left in FIG. 1, which is conveyed on a conveyor surface 23 intermittently from processing station to processing station by means of conveyor belts.
  • 1 shows conveyor belts 24 and 25 lateral stop bars 26 and 27, the conveyor belts 24, 25 being adjustable in the direction of the double file, that is to say in the conveying direction, and the stop bars 26, 27 being adjustable perpendicular to the conveying direction in the direction of the double file assigned to them , so that when the conveyor belts on the one hand and the stop bars on the other hand are correctly adjusted, a defined point F ⁇ of the carton blank 10 is conveyed to a predetermined fixed point F on the conveying surface 23 (the other conveyor belts which are used to remove the carton blank are not shown for the sake of simplicity) .
  • the entire facilities for conveying and positioning the cardboard blank 10 are usually in a frame consisting of Frame legs 21, 22 housed, which are usually supported on the floor (see. Fig. 3).
  • the cardboard blank 10 has a cutout in the sense of a window 10a, which is to be closed during further processing with a PVC transparent film, hereinafter referred to as window blank 11.
  • window blank 11 a PVC transparent film
  • the machine must therefore ensure that, according to the sequence of cardboard blanks 10, a corresponding sequence of window blanks 11 comes to lie in a defined position above the conveying surface 23 and above the cardboard blank 10 and is lowered from there onto the cardboard blank 10 with high precision, in such a way that the edge surfaces previously provided with glue around the window cutout 10a are covered exactly by the edge surfaces of the window blank 11 and thus stick together.
  • the window blanks 11 must therefore be transported over the conveying surface 23 in such a way that their center F ⁇ chosen in accordance with the point F ⁇ also comes to lie above the fixed point F of the conveying surface 23, it then also being necessary to ensure that the alignment of the window blanks 11th takes place parallel to the corresponding edges of the window section 10a.
  • a (further) station 30 is switched on perpendicular to the frame legs 21, 22 of the production line 20, the movement sequences of which run essentially perpendicular to the conveying direction of the conveying surface 23.
  • the station 30 initially contains a rectangular frame 40, the longitudinal axis BB of which is perpendicular to the longitudinal axis of the conveying surface 23 runs.
  • the frame 40 protrudes on both sides of the corresponding frame legs 21, 22 of the production line 20, so that there is space for further frame parts 41, 42, which each serve to hold a magazine 31, 32, the structure of which is explained in more detail below.
  • a comb-like (see FIG. 2) stop bar 43 is supported on the frame 40, which runs through the fixed point F.
  • Two guide tubes 35, 36 are guided symmetrically to the central longitudinal axis B-B of the frame 40, the ends of which are mounted in the end faces of the frame 40 and the central regions of which are guided through the stop bar 43 and are held by the latter.
  • the stop bar 43 thus separates the station 30 into a right and a left half, each having a magazine 31 and 32 and extending to the fixed point F above the conveying surface 23.
  • a transport carriage 33, 34 is now each slidably mounted in the left and right halves, in such a way that its one end position above the associated magazine 31 (for the transport carriage 34) and 32 (for the Transport carriage 33) comes to rest and the other end position is defined by a stop on the stop bar 43.
  • the task of these two transport slides 33, 34 is to take the window blanks of PVC transparent film stacked in "their" magazine 31 or 32 in cycles, to transport them towards the conveying surface 23 and to position them there (ie with their fictitious center F ⁇ above the fixed point F ) on the cardboard blank 10 underneath.
  • the transport carriages 33, 34 are provided on their underside with a counter plate 37 which can be moved vertically in the respective transport carriage via telescopic or cylinder guides 39 are so that the counter plate 37 in the direction of the magazine or in the direction of the folding box blank 10 can be lowered and raised again.
  • the counter plate 37 has pressure outlet openings 38 on its underside, which can be connected to a vacuum unit (for example a vacuum pump) or an overpressure unit by means of line connections (not shown for the sake of simplicity).
  • a window blank 11 can thus be removed from the magazine, conveyed to the fixed point F and deposited there on the cardboard blank 10, as shown in FIG. 3 the double arrows pointing to the relevant positions are indicated.
  • magazines 31 and 32 will now be described in more detail below, as can be seen in particular from FIG. 2 with regard to magazine 31:
  • the magazine 31 consists of a base plate 312, which is connected via screw connections to the frame parts 41, 42 arranged on the end face and held therein. By adjusting these screw connections, a fine adjustment of the base plate and thus of the window blanks 11 can be achieved in particular in the sense that corresponding edges of the blanks 11 and the window cutouts 10a run absolutely parallel to one another.
  • the base plate 312 is provided with radially extending (not shown) elongated holes in which a plurality of tubes 311 are guided. This type of displacement allows any desired position on the base plate 312 for the folding box blanks, so that appropriate tests can be used to ensure that the window blanks 11 actually move the window cutout 10a in the cardboard blank 10 as evenly as possible after they have been transported through the transport slides Cover overhang. It goes without saying that the adjustment of the Window blanks 11 on the base plate 312 in connection with the corresponding adjustment of the conveyor belts 24, 25 and the stop bars 26, 27 must be seen.
  • a lifting table 310 is guided between the tubes 311 and is pressurized from below. This is symbolically represented by a spring; of course, another force can also be provided. Centered by the tubes 311, the window blanks 11 are stacked one on top of the other on the lifting table and are thus pressed from below (not shown in more detail) to the stop located in the region of the upper end face of the tubes 311. To the side of this area are two compressed air nozzles 313, the air jet of which runs parallel to the surface of the stack of window blanks 11, so that a certain negative pressure can be achieved above the top window blank.
  • the two counter plates 37 move downward.
  • the counter plate 37 of the transport carriage 33 moves toward the uppermost window blank 11 in the stack in the magazine 32, the counter plate 37 of the transport carriage 34 moves with its already detected blank onto the carton blank 10 which is now positioned correctly on the conveying surface 23.
  • the printing unit is switched on and the film blank is blown off via the pressure outlet openings 38, the effect of the glue application in the edge areas of the window cutout 10a having a supporting effect and possibly also mechanical aids (not shown) can be provided in the form of elastic strips, which prevent the film blank from sticking to the counter plate 37 when it is steered upwards again.
  • the counter plate 37 of the transport moves slide 33 down, and at the same time the compressed air nozzles 313 and 323 are activated and the pressure outlet openings 38 in the counter plate 37 are connected to a vacuum unit, so that the top window cut 11 is separated from the stack by these two effects and gets stuck on the counter plate 37 .
  • the movements of the transport carriage and their counter plates can be controlled pneumatically, hydraulically or electromechanically as required, as is considered to be favorable in individual cases.
  • the above description was given on the basis of the exemplary embodiment of cardboard cut-PVC clear window cut.
  • the method and the machine can also be used for other materials, for example cardboard blanks of different thickness, different quality or special printing.
  • a variant of the control of the lifting table 310 provides that the upper position of the uppermost window blank is predetermined by a light barrier which, for example, controls the piston of a pneumatic element arranged under the lifting table 310.
  • the counter plate 37 is equipped with a proximity switch that generates an output signal when the minimum distance to the top window cut is undershot. The control then runs as follows:
  • the lift table 310 is in its upper position; when the counter plate 37 has reached the said minimum distance, the proximity switch switches on the vacuum supply of the pressure outlet openings 38, whereupon the top blank is sucked in; at the same time or shortly thereafter, the lifting table 310 moves down with the remaining stack in order to support the separating process.
  • the pneumatic element is then actuated again via a switch arranged on the path of the transport carriage and the piston moves the lifting table 310 back into its upper waiting position until the transport carriage "returns".
  • the term "window cut” does not necessarily mean that the PVC transparent film could only be used in one area of the box cut, it is also possible to produce packaging which is practically half cardboard and half PVC hard film, in which the folding lines extend both over the cardboard part and over the PVC film part. It goes without saying that the extreme positioning accuracy of the solution according to the invention is of particular importance in the case of such designs, since the adjoining folding lines must be exactly aligned with one another so that the finished folding box can be folded properly.
  • any first and second parts can be connected to the machine described, for example rubber rings (as first parts) with folding bags (as second parts) for the production of dust bags for vacuum cleaners, in which the rubber rings are positioned as a seal around the circular opening of the folding bag and have to be connected to them.
  • the transport slides alternate on a straight path from magazine 31 or 32 to production line 20. It is of course also possible to provide, for example, a circular or arc-shaped path instead of this straight path, where then at least one or, for example, up to four transport slides be moved carousel-like across the production line. Both an alternating and a cyclically rectified rotation of these transport slides is then possible.
  • Such a configuration allows an increase in the cycle of the production line by a corresponding increase in the number of transport slides, since, for example, two transport slides can always place window cuts on the production line at the same time, so that two fixed points F ⁇ and F ⁇ are defined.
