Definitions

the present invention relates to the automatic packaging of objects, the packaging of which is done by welding a flat film onto a matrix comprising cells previously filled with said objects.
the invention relates to a device which can be inserted on an automatic packaging line, in particular in the pharmaceutical industry, and intended to eliminate and possibly recycle objects which have not been packaged according to the standards laid down.
a honeycomb matrix generally made of PVC, runs in the form of a continuous film between transport rollers.
One or more distributors located above the film fill the cells corresponding to the content of successive plates, the number of cells per plate being determined at the start according to the desired packaging.
a sealing film generally made of aluminum, sticks to said matrix, thus trapping the tablets.
the various successive plates are then checked by a detection barrier, cut and packaged after elimination of the badly filled plates.
a device intended to automatically manage incidents of filling of the wafers obtained by sealing a film on a honeycomb matrix filled with the products to be packaged, which is characterized in that, interposed between the automatic barrier detecting the filling anomalies and the sealing of the film, it comprises the combination of a suction system A intended to completely empty the badly filled platelets and a recovery system B connected to the suction system allow the contents of the empty platelets to be collected under mild conditions and to store it temporarily.
Systems A and B cooperate together for the final result, which is the automatic management of filling incidents on a packaging line without reducing the production rate, without increasing the cost and with high reliability.
This hopper shown in FIG. 1, essentially comprises two zones 20 and 21 separated by a flexible wall 22 permeable to air, a drain hatch 23, an inlet pipe 24 connected to the outlet pipe 19 of the device d 'suction described above by a pipe 25 and an outlet pipe 26 connected to a central vacuum (not shown in the figure).
the device described above operates in the following manner:
the central vacuum unit being in operation, a vacuum is created through the assembly constituted by the system of recovery B, the flexible pipe 25 and the suction system A, the air entering the device through the recess in the part 13 of the suction system.
the flap 7 is in the low position.
the air current created by the depression rushes through the passage 14 into the openings 6 and 8 which are coincidentally.
the detector responsible for checking the contents of the wafers which can be a memory image analyzer, detects a filling anomaly, the signal taken in the step of the machine triggers a relay which actuates the jack 10.
the shutter 7 then lifts; the slot 6 is closed by the lower part 9 of the flap 7.
the air flow created by the depression then rushes through the passage 15 and the slot 4. All the tablets which are presented in line opposite the space 17 are sucked in by suction.
the signal sent to the jack 10 is programmed and maintained so that all the tablets corresponding to a complete wafer are eliminated. The latter are conveyed through the flexible pipe 25 to the recovery hopper where their race ends after being damped on the flexible wall 22.
the honeycomb matrix continues its advancement until the content of a new wafer be examined by the detector. If the new plate is correctly filled, the signal resulting from the control actuates the jack and causes the shutter 7 to descend. The packaging chain then resumes its normal operation.
the honeycomb matrix is then closed by welding the aluminum flat film and then cut to the dimensions of the wafer.
cylinders with low response times are used, for example cylinders which can respond to stresses of the order of 600 strokes per minute (300 back and forth). Given the length of the plates (5 to 10 cm), such a rate corresponds to a movement of the honeycomb matrix from 25 to 50 cm / sec, which is much higher than the operating speed of current packaging machines.
the suction power is a function of the characteristics of the tablets (weight, size, shape), the speed of travel of the blister matrix and the pressure drops in the device.
a depression of 270 mm of mercury is sufficient to carry out a total extraction, reliably, when the rate of the machine is adjusted at 400 cells per minute on 8 front tracks.
the device as described above in its organs and its functions constitutes the basis of the invention. It is likely to present particularities of execution which make its operation easier or its realization more economical. Thus, it is particularly interesting to choose the materials according to mechanical needs.
the flaps 7 which must slide freely between the parts 1 and 5 are preferably made of a material which does not seize up, which does not erode under the conditions of use and which does not need to be lubricated in order to '' avoid possible pollution of the tablets.
These shutters can preferably be made of a material based on fluoropolymer such as Teflon (N.D. Dupont) or polycarbonate or nylon.
the part 13 can be machined from a similar material, as can the lower part 3 of the body of the device. The use of these materials in particular facilitates the sliding of the tablets during extraction.
the shape of the parts can vary within wide limits, but it is obvious that a person skilled in the art will have an interest in get as close as possible to the optimal conditions that govern the flow of fluids and solids.
the angle formed by the base 3 of the body of the device with the horizontal plane can vary between 35 and 70 °, but it is preferably close to 45 °.
the angle formed by the base of the part 13 with the horizontal plane can be variable, but it is preferably close to 25 °.
the bar 16 preferably has a triangular profile as shown in FIG. 2 in order to facilitate the displacement of the suction air stream which flows either along the path 15 (extraction of the tablets) or along the path 14, 6, 8 and 4 (normal operation).
the connection of the slot 4 of the body of the device with the extraction chamber 18 must be such that the tablets do not meet sharp angles but on the contrary curved surfaces which facilitate their smooth evacuation.
the wall 22 must be such that the end of the stroke of the tablets is cushioned to avoid breaking them.
This wall may consist, for example, of a stretched elastic membrane, pierced with holes large enough to allow air to pass and small enough to retain the tablets.
this wall 22 can be rigid, for example a metal wall pierced with large holes to let air pass and covered with a flexible and porous mattress, for example a polyurethane foam or a similar material having the same function.
the suction and recovery-storage system therefore makes it possible to automate the packaging chain and to obtain, without stopping the chain and without additional handling, i) correctly filled wafers which are packaged, ii) completely empty platelets which are discarded and burned; and iii) recovered tablets.
the device according to the invention can be coupled to a sorting system which makes it possible to separate the good tablets from those that are broken or damaged.
the sorting system can be constituted by any known device adapted to the nature and shape of the tablets or of the objects to be sorted. It can be a simple grid vibrator whose mesh size is calculated to allow the elimination of objects not having the required dimensions.
the present invention is primarily suitable for packaging machines for medicines, but it is obvious that it can find application in other fields such as the packaging of foodstuffs such as confectionery or even the packaging of small objects used in hardware.
the invention applies to any packaging using the principle of trapping objects between a honeycomb matrix and a film serving as a seal.
