Definitions

  • the present invention relates to packaging machines, particularly the invention refers to a device and a method for feeding containers, for instance flexible pharmaceutical containers.
  • the feeding devices usually consist of a horizontal or inclined support on which the containers to be manufactured are positioned.
  • the flexible containers are usually inserted on suitable supports, constituted by at least two parallel rods interconnected at the ends by a fixed handle and removable handle.
  • the assembly rods-containers constitutes a so-called magazine.
  • the operator After having transferred the containers in the feeding device, the operator checks the correct containers distribution and usually inserts a gravity pusher which presses the containers forcing them to regularly slide toward the picking area.
  • the pusher which is usually constituted by a weight sliding on the feeding device supports, must be manually inserted and disconnected by the operator at each loading sequence in order to avoid possible containers jamming or blocking, which may happen because of the sliding frictions between the containers and the side and external lower guides of the feeding device.
  • the main drawback of the known feeding devices consists in the manual transfer of the containers, which is difficult and delicate to be performed and requiring one or more skilled operators for transferring with great attention the content to the feeding device of the packaging machine.
  • Another drawback of the known feeding devices consists in the possibility that the containers, sliding along the slanted guides of the feeding device, can jam or even obliquely stop with respect to the sliding direction.
  • the main object of the present invention is to propose a device and a method for feeding containers in which the manual loading operation is reduced and simplified, without requiring the use of skilled operators, and such to avoid the contact of the containers by the operator, so preserving the integrity and the sterility of said containers.
  • Another object is to propose a device and a method, which allow moving fifty-sixty containers per minute, for each packaging line. Further object is to propose a feeding device having a safe and continuous operation, without containers jamming or blocking.
  • numeral 4 indicates a feeding device for flexible containers 101 including at least two bars 401, usually four, parallel and slanted downwards, preferably of around 30° with respect to a horizontal plan.
  • the device 4 is fit in a packaging machine of flexible containers for sanitary and/or pharmaceutical products between a store and a conveyor of the same machine.
  • the bars 401 are supported by gripping means, first 402 and second 403, of the device 4 and each one having a two couples of mobile opposed jaws, upper 404 and lower 405.
  • the jaws, upper 404 and lower 405, are reciprocally connected in such a way to synchronically rotate with opposed direction and so that the lower jaw 405 rotates more than the upper jaw 404 to allow the free slide of the containers 101 along the bars 401 when the jam is not gripping the bars.
  • the lower mobile jaw 405 further has a tooth 411 fit to engage a seat 410 of each corresponding bar 401 for keeping the axial position of this latter.
  • the shape and the dimension of the mobile jaws, upper 404 and lower 405, are such to guarantee the exact support and axial reference of the bars 401 even in case these latter are alternatively supported by only one of the two gripping means, first 402 and second 403.
  • the bars 401 usually have circular or elliptical section and each one has in correspondence of an upper end an insertion pivot 420, eccentric with respect to the axis of the related bar, for the removably connection with a magazine 100.
  • the magazine 100 are constituted, for instance, by two rods 103, each having a first end rigidly connected to a fixed handle 104 and the second end removably connected to a detachable handle 102 provided with fixing pivots 106 which are inserted to the ends of the two rods 103, in correspondence of respective seats 105.
  • the cross section dimensions of the bars 401 are grater than the dimensions of the rods 103 and entirely filling the spaces or the openings of the containers 101, for instance monodose container strips, allow these latter to freely slide by gravity along the bars 401 without blocking or jamming.
  • the feeding device 4 has couples of presence sensors first upper 416 and first lower 406, second upper 417 and second lower 407, third upper 408 and third lower 418 and a minimum load sensor 409.
  • Said optical or inductive or capacitive sensors provide a signal, usually digital, associated to the presence or absence of the containers 101 in the feeding device, and active the different operational phases for the feeding sequence of the containers 101.
  • the operation of the device provides an operator manually insert a predefined number of magazines 100, from one to three in parallel and usually two, into the feeding device 4.
  • the insertion is carried out by inserting the insertion pivots 420, at the upper ends of the rods 401, inside the corresponding tubular housings 105, at the free ends of the rods 103, in an insertion condition E.
  • a suitable loading device 3 can also automatically execute this manual operation.
  • the magazines 100 are integral with feeding device 4, since are rigidly connected to this latter.
  • the assembly magazines/ support bars 401 is rigidly supported by the gripping means, first 402 and second 403.
  • the alternate and not contemporary opening of the opposed jaws 404 and 405 of one of the gripping means, first 402 or second 403, does not cause instability to the assembly magazines/ support bars which, in fact, remains always tightly and statically coupled by means of the remaining support.
  • a first container subgroup of the containers 101 group is stopped by the operator or by the loading station 3 and a second container group slide along the rods 103 and the bars 401 up to stop in correspondence of the first gripping mean 402.
  • the condition of container absence, sensed by the first upper sensor 416, and by the couples of sensors second 417, 407 and third 418, 408 and the condition of container presence, sensed by the first lower sensor 406, enable the opening of the first gripping mean 402, as shown in figure 2A, corresponding to a first discharging condition G, to allow the second container subgroup sliding and moving in correspondence of the second gripping means 403.
  • the condition of container absence, sensed by the first couple of sensors 416, 406, by the second upper sensor 417 and by the third couple of sensors 418, 408, and the condition of containers presence, sensed by the second lower sensor 407, enable the discharge of the second container subgroup by the operator or by the loading station 3.
  • the containers slide up to stop in correspondence of the first gripping mean 402, which in the meantime is closed again.
  • the condition of container absence, sensed by the sensors first upper 416, second upper 417, third upper 418, third lower 408 and by the minimum load sensor 409, and the condition of container presence sensed by the sensors first lower 406 and second lower 407, enable the opening of the second gripping mean 403, as shown in figure 2B, which allows the second container subgroup to slide toward a picking area 5.
  • the second gripping mean 403 is maintained in open position until the third couple of sensors 418 and 408, respectively sensing the absence and the presence of containers 101, enable its closure.
  • the minimum load sensor 409 senses the presence of minimum number of containers to be transferred to a conveyor downstream the feeding device 4.
  • the first gripping mean 402 is opened to allow the first container subgroup sliding toward the second gripping mean 403.
  • the condition of container absence of the second upper sensor 417, of the third couple of sensors 418, 408 and of the minimum load sensor 409 and the condition of container presence of the second lower sensor 407 enable the opening of the second gripping mean 403, to allow the first container subgroup sliding toward the picking area 5.
  • the condition of container absence, sensed by the second couple of sensors 417, 407 and by the third upper sensor 418, and the condition of container presence, sensed by the sensors third lower 408 and of minimum load 409, enable the closing of the second gripping mean 403 and the assent for the extraction of the empty magazines from the rods 401, by the operator or the loading device 3.
  • the device is fit to move at least fifty/sixty containers for packaging line and however is related to the operational cycles of the packaging machine in which said device is fit.
  • the feeding device 4 is completely controlled by electronic calculation and control means, not shown, fit to control the phase coincidence between at least the gripping means, first 402 and second 403, according to the signals received from the presence sensors first upper 416 and first lower 406, second upper 417 and second lower 407, third upper 408 and third lower 418 and of minimum load 409.
  • the main advantage of the present invention is that to provide a device for feeding flexible containers in which the manual loading operation is reduced and simplified, not requiring the use of skilled operators.
  • Further advantage is to furnish a device that allows moving at least fifty/sixty container per minute, for each packaging line.
