Definitions

  • the invention relates to a machine for producing folding boxes (so-called trays) from blanks, in each of which a blank is removed from an interchangeable magazine at the bottom, placed on two parallel guide rails and conveyed by means of a conveying device to an interchangeable shaping device with an end stop for finishing the folding box , wherein a connector substance is applied at predetermined points of the blank by means of an application device, and wherein the shaping device consists of a stamp and an underneath, open at the top and bottom.
  • the application heads operated with glue are arranged in the removal area of the magazine, a corresponding number of application heads being provided with regard to the areas of the respective blank to be provided with glue.
  • a swivel device By means of a swivel device, the removed and glued blank is conveyed to the molding device, where it has to be centered over the shaft.
  • corresponding holding and adjusting or centering devices provided with spindles and cranks, are provided, which are complex to set up and cumbersome and time-consuming to use if a different tray blank size in the machine; should be processed, since in this case both the magazine and the molding device must be replaced.
  • the application of glue to the predetermined areas of the blank is inaccurate, since the application heads are relatively far away from these areas and a fairly large spraying distance has to be covered as a result, which also results in increased glue consumption.
  • DE-A-18 04420 describes another machine of the type in question, in which two mutually parallel and fixed guide rail parts extend from the blank magazine to a folding shaft, where they combine to form a plate, the opening of which simultaneously opens the opening of the Folding shaft forms.
  • a conveyor element moves back and forth between the two rail parts in order to promote the cutting from the magazine to the folding shaft.
  • Above the folding shaft is a combined tool which is mounted independently of the rail parts and which is a gluing unit and a form stamp at the same time.
  • a disadvantage of this machine is that when changing the blank, in addition to the magazine and the folding shaft, the guide rail parts and inevitably also the gluing unit must be replaced, since the latter in particular is combined with the form stamp.
  • the object of the invention is to provide a machine of the type mentioned in the introduction, which, in addition to structurally simplifying the adjustability of the guide rails and the application heads, as well as being more cost-effective to manufacture, can be converted more quickly and in a more user-friendly manner to other tray cut sizes, in which the application heads can be replaced alone and in which the connector substance can be applied precisely.
  • the solution is based on the introductory machine and is characterized in that the two guide rails can be adjusted to one another in the horizontal state, that the magazine has two lateral, downwardly extending and opposite, fixed stops, against which the adjustable guide rails come to rest Can be brought that each guide rail carries in a conventional manner at least one applicator head adjustable in the longitudinal and vertical direction of the rail and that each applicator head is assigned a length-adjustable switch actuated by a driver finger of the return run of an endless conveyor for operating the applicator head.
  • the machine consists of the usual, not explained frame 1, which has two mutually parallel and horizontally extending guide rails 2 and 3 and further above one end region of the guide rails with a magazine 4 for receiving a folding box blank 5 and in the other End region of the guide rails is provided with a shaping device 6.
  • the shaping device consists of a punch 7 located just above the guide rails 2, 3 in the rest position, which is attached to the lower end of a vertical support 10 guided by pairs of rollers 8 and 9 and can be moved in the vertical direction by means of a pressure medium cylinder 11 acting on the support 10, and from one below the stamp 7 and aligned on this, as well as open at the top and bottom 12.
  • the guide rails 2 and 3 have an L-shaped cross section and are arranged such that one leg of the rails points upwards, while the other two legs run horizontally, facing each other .
  • a blank 14 which can be clearly seen in FIG. 2 and is removed from the stack 5 of the magazine 4 by means of a conventional suction gripper device 15a, can be placed on the guide rails and by means of a conveyor device 15 arranged below and between the guide rails from the area of the magazine 4 be promoted to the molding device 6.
  • the blank 14 is passed underneath the application heads 13 and provided with a connector substance, as will be explained.
  • the guide rails 2 and 3 are fastened to transverse twin bars 16 so as to be adjustable transversely to their longitudinal direction.
  • the twin spars each consist of two parallel rods 16 a, b, which form a slot 17 between them (FIG. 4), through which struts 18 connected to the guide rails 2 and 3 protrude upwards, to which conventional, hand-operated clamping members 19 engage.
  • the guide rails can thus be adjusted at a horizontal distance from one another and can be locked by means of the clamping members 19.
  • the magazine 4 is provided with two fixed, opposite, lower and arm-shaped stops 20 which extend so far down that a guide rail can come to bear against such a stop on the inside.
  • the guide rails can be easily adjusted to a newly inserted magazine 4, so that the blank 14 removed at the bottom is readily oriented laterally when it has been placed on the guide rails 2, 3.
  • the conveyor 15 consists of a conventional endless conveyor 21, the z. B. may have a rocker arm drive chain 22 which is provided with drive fingers 23 with which the blank 14 is conveyed along the guide rails 2, 3.
  • the conveyor also consists of a sliding device 24 adjoining the endless conveyor 21, which takes over the blank 14 from the conveyor 21 and conveys it further into the end position in the shaping device 6.
  • the sliding device has a sliding arm 25 which is resilient in the vertical direction and has a sliding element 26 which comes to rest against the blank 14 to be conveyed further. In the starting position of the sliding arm 25, it bears against an upper guide 27 which keeps the blank 14 pressed down when it runs over the sliding arm 25.
  • the sliding arm 25 is fastened to a reversible drive cylinder 28, at the front end of which a stop-actuated, conventional reversing element 29 is provided.
  • This reversing element 29 comes to rest against a stop 30 when the blank 14 in the shaping device 6 has reached its end position. Then the drive cylinder 2. moves into its Starting position ( Figure 1) back.
  • each shaft 12 of the molding device 6 can be replaced.
  • each shaft 12 is connected to a frame 31, which in turn is attached to the frame of the machine. This enables the shaft 12 to be replaced quickly.
  • the rear region of the shaft 12 in the conveying direction is provided with a fixed end stop 32 which projects into the region between the two guide rails 2 and 3, as can best be seen from FIG.
  • This end stop defines the end position of the blank 14 conveyed into the shaping device 6, as seen in FIG. 1, as shown in FIG.
  • the punch 7 of the shaping device 6 aligned with the shaft 12 can now be moved downwards in order to press the blank 14 into the shaft 12 and thereby form the final shape of the blank 14 into a finished folding box.
  • a plurality of electrical switching elements 33 are also provided on the frame 1 of the machine in the area of the return run of the endless conveyor 21, each of which is assigned to an application head 13 and controls their operation.
  • the control takes place in such a way that the driver fingers 23 of the driver chain 22 run past the switching elements 33 and interrupt or reflect a working beam of the elements, whereby the operation of the application heads is switched on or ended.
  • the switching elements 23 thus preferably consist of conventional transmitting and receiving elements.
  • These switching elements are fastened to arms 34 which, on the other hand, are arranged so as to be adjustable in the longitudinal direction of the return run of the endless conveyor chain 22 and can be fixed by means of known clamping elements 35.
  • a blank according to FIG. 2 is to be formed into a folding box, the folding box that is created being referred to as a so-called tray.
  • the folding box that is created being referred to as a so-called tray.
  • Such blanks can also be processed in the machine described above, which have a lid as a finished folding box.
  • the folding boxes are generally made of cardboard or pate material.
  • the blank 14 deposited on the guide rails is conveyed in the direction of the shaping device 6 by means of the conveying device 15.
  • a conventional sequential circuit which is controlled by the switching elements 33, causes the blank 14 to be stopped and / or the application heads 13 to be put into operation.
  • the blank 14 is stopped and the application taps 13 are operated briefly so that an application of a binding substance, which can consist of glue or an adhesive, is carried out , but preferably consists of hot glue, can be made on the corresponding tab parts of the blank.
  • the stamp 7 can move down in order to press the prepared blank into the shaft 12 in the usual way.
  • the side flaps of the blank 14 are folded upward in a known manner, the flap parts to be connected to one another being brought into contact with one another so that they can connect.
  • the shaped blank 14 remains in the shaft 12 for a correspondingly long time, as can also be seen from FIG.
  • the stamp 7 has now been retracted so that a new blank 14 can be inserted into the molding device 6.
  • the stamp 7 then descends again, the lowest folding box 36 in the shaft 12 being ejected from the shaft below and brought onto a discharge conveyor 37.
  • the application head 13 or the application heads 13 are each assigned to the corresponding guide rails 2 or 3.
  • the procedure can also be such that one or more application heads are provided between the opposing application heads 13, if this is desired for corresponding blanks. Seen in the transverse direction of the guide rails are then z. B. three guns 13 are provided.
