Definitions

  • the present invention relates generally to machines which are intended to group and package objects and, in particular, containers, and in particular to a machine which is intended, starting from a cardboard blank, to form a tubular multi-piece pack around such previously arranged containers.
  • Such a machine normally has a blank magazine which is able to hold a stack with numerous blanks, from which the blanks are individually removed by a suction arm or the like and placed on the web for the objects.
  • a blank magazine of the known type it is also common for a blank magazine of the known type to be arranged over the web for the objects, the blanks taking a slightly inclined position with respect to the vertical and the direction of the stack of blanks being parallel to the web for the objects.
  • the suction device is mounted about a horizontal axis perpendicular to the path for the objects.
  • this known device has certain disadvantages.
  • the cutting magazine increases the vertical space requirement of the machine, while its fairly high position above the machine makes refilling the magazine extremely cumbersome. The capacity of the magazine is ultimately limited by the length of the machine.
  • the present invention has for its object to eliminate these disadvantages of the prior art and to propose a new device for the cutting magazine, which offers a very high capacity, the space requirement of the machine neither in the longitudinal direction nor vertically raised, allows the installation of several magazines next to each other to enable high performance and is easier to refill.
  • Another object of the invention is to improve the effectiveness of gripping the individual blanks by means of a suction device in a magazine with a very high capacity.
  • the present invention thus relates to a packaging machine which is designed to fold blanks of cardboard or the like in the course of a movement of the combined objects and the blanks in a certain plane and in the longitudinal direction of the machine in order to fold the combined objects, and in the upper region a blank magazine which receives a blank stack and means for transferring the individual blanks from the magazine to the plane of movement of the combined objects and the blanks, the machine being characterized in that the magazine is arranged laterally with respect to the longitudinal direction of the machine, that the stack of blanks extends substantially transversely to said longitudinal direction of the machine and that the transmission means are arranged such that the blanks are transmitted by movement in a plane which is substantially perpendicular to said longitudinal direction.
  • a packaging machine 100 which in the present case is intended to fold and fasten blanks around ordered groups of objects, such as cylindrical containers for beverages, for tubular multi-piece packs of the inherently classic type to build.
  • the machine 100 has a frame with a conveyor belt for transporting the objects and the blanks in a horizontal plane P and in a direction of movement indicated by the arrow SM, this arrow defining the longitudinal direction of the machine.
  • the principle of this machine is to bring the flat blanks D one after the other into the plane P, to have a group of objects conveyed onto the provided blank, to fold this blank around the objects, and to secure it with itself by means of a glued or inserted closure to fix.
  • the various devices used to carry out these operations can be entirely classic and are not described here.
  • At least one laterally arranged blank magazine is provided (in the present case there are two magazines side by side, 200 or 200 '), which collects a stack of flat blanks D from one direction (arrow F in FIG. 3) perpendicular to the longitudinal direction.
  • FIG. 2 shows the magazine 200 in its entirety and also gives a diagrammatic representation of a device for transferring the individual blanks from the magazine in question to the plane P of the machine 100.
  • this device comprises one or more rotating elements 110 which are rotatably mounted about an axis 111 and which, due to the special arrangement of the magazine, extend parallel to the longitudinal direction of the machine.
  • This axis 111 is rotated clockwise in Fig. 2 by suitable motor-driven means so that it is synchronized with the device for transporting the objects in the direction SM.
  • the or each rotating element 110 has the general shape of a triangle with sides of equal length and has a suction device 112 in the region of each tip, which is controlled by a pneumatic control circuit so that a single blank D is picked up at the height of the magazine 200 and after one Release about 90 ° rotation with the help of the aforementioned motorized means above the P plane.
  • It comprises a conveyor belt 206 which defines a horizontal support plane P 'for a main stack P1 of blanks D, this belt being mounted between two rollers 202, 204 to by means of a motor 210 and one between the output shaft of this motor and the roller 204 provided band 208 to be driven in the direction of arrow F.
  • Longitudinal guides 216 which run parallel to the direction of arrow F, laterally support the blank stack.
  • the blanks D in the stack P1 are held on the upper side with respect to their direction of movement (left in FIG. 4) by holding elements in such a way that they assume an oblique position of approximately 20-30 ° with respect to the vertical.
  • These holding elements have one or more rollers 228 in the upper part, which are movably mounted on a frame of the magazine, and two lateral rollers 234 in the central region, which are also movably mounted on arms, which in turn are fastened to a carrier of the frame just mentioned .
  • the roller (s) 228 and the side rollers 234 are positioned so that the left most blank is supported on the belt 206 practically perpendicular to the axis of the drive roller 204.
  • the blanks D in the present example consist of a lower part Da with a width that is slightly smaller than the distance between the guides 216, and of an upper part Db with a narrower width (see FIG. 1 ).
  • the height and the width of the rollers 234 are selected so that they can interact with the lateral edges of the upper region of the lower part Da of a blank D. However, if the blank in question begins to fall due to the implementation of a method described later, the rollers are at the level of the narrower part Db of the blank and are no longer in engagement with it. On the other hand, when the cutting process is initiated, its upper part no longer lies against the upper roller 228.
  • a carrier plate 226 which slopes slightly to the left and is intended for a second stack P2 of blanks which are transferred from the main stack P1, as we will see later.
  • the carrier plate 226 in the present case has a stop 224 (alternatively several stops) which protrudes a short distance upwards above the plane of said plate.
  • Two short side stops 214 are also provided at an intermediate height of the blanks of the second stack P2. These side stops are attached to a support of the frame of the magazine by oblique arms.
  • a movably mounted upper holding roller 222 is also connected to the frame support by an oblique arm.
  • the stops 224, 214 and the roller 222 are arranged so that the blanks of the second stack P2 are at a smaller angle with respect to the vertical, for example from 10 to 20 °, than the blanks of the main stack P1.
  • FIG 4 shows a part of the suction device with the rotating element 110, a suction head 112 provided on the illustrated tip of the element 110 and a suction device 113 which bears on the exposed blank on the left side of the stack P2.
  • the magazine 200 has two optical sensors 230, 232.
  • the sensor 230 is arranged just to the left of and above the drive roller 204.
  • the sensor 232 is arranged in the middle and just above the conveyor belt 206.
  • the main task of the magazine described above is to receive the significant quantities of cuttings on the conveyor belt 206 (stack P1), to form the second stack P2 with a smaller capacity from the stack P1, to keep this second stack at a barely changing filling level the reasons explained later) and the blank of the suction device lying on the left side of the stack P2 for transmission.
  • the optical sensor 230 has the task of determining the fill level of the stack P2. If the stack P2 does not reach the sensor 230 - as shown in FIG. 2 - a corresponding control circuit drives the conveyor belt 206 in the direction of the arrow F. The blanks located on the left side of the main stack P1 are thus moved to the left on their lower edge and the downward movement of the conveyor belt 206 around the roller 204 causes these blanks to fall down under the action of gravity.
  • the movable mounting of the roller 228 and the rollers 234 provides minimal resistance to this movement. With this falling movement - as already mentioned - the upper edges of the blanks are no longer held by the roller 228 and their intermediate areas are no longer held by the rollers 234, so that these blanks released under gravity can freely fall to the second stack P2 to replenish it.
  • the control device stops driving the conveyor belt 206, which ends the filling process of the stack P2.
  • the large-volume magazine according to the invention thus forms a small "buffer” stack P2, which eliminates these problems and makes the total capacity (stack P1 and P2 together) of the magazine practically unlimited.
  • a magazine according to the invention with a “buffer” stack with a device other than the lateral device according to the invention can also be used advantageously.
  • the command to actuate the conveyor belt 206 in the direction of arrow F is preferably given on a pulse basis, ie the pulses (possibly with a controllable duration and in the present case in of the order of 100 milliseconds) act on the drive motor 210.
  • This impulse-based command is also preferably given for a limited period of time - typically a few seconds - with the aid of a corresponding delay time in the control circuit. Only after this delay time has elapsed is the sensor 230 queried to determine whether the stack P2 has been filled up sufficiently. If this is not the case, a new process for filling the stack P2 is carried out as described above. If necessary, this process is then repeated.
  • the magazine 200 is of a substantially constant width and is only slightly wider than the blanks, it is of course easy to place several magazines next to one another in the area above the machine if the speed of the blank transfer with a single magazine is not sufficient to accommodate to keep up with the speed of the machine itself.
  • the capacity of the magazine 200 can be expanded as desired by increasing the length L of the conveyor belt (FIG. 4) - without affecting the longitudinal dimensions of the machine 100 itself.
