Definitions

  • the invention belongs to the vast technical field concerned with automatic machines, such as, for example, machines for the continuous packing of articles (e.g. medicines or cosmetics) in containers (e.g. cases), of the kind comprising two coplanar lines, side by side, one line being for the infeeding of the articles and the other for the infeeding of the containers, in the region of a station where the articles are inserted into the containers.
  • automatic machines such as, for example, machines for the continuous packing of articles (e.g. medicines or cosmetics) in containers (e.g. cases), of the kind comprising two coplanar lines, side by side, one line being for the infeeding of the articles and the other for the infeeding of the containers, in the region of a station where the articles are inserted into the containers.
  • the article infeed line consists of a number of trays, integral with a pair of looped chains moving in a line perpendicular to the axis of the- trays.
  • the trays are designed to receive, from a magazine, (for example, of the kind defended in Italian patent application No.3597A/81) a preset number of articles (for example, 1,2,3, etc.). This means that the device which "unlatches" the articles from the magazine has to be adjusted (by the operator on the spot) and a detector provided, between the magazine and the aforementioned station, to detect the height of the pile of products in each tray.
  • the detector is mounted so that it can be adjusted'in height when the number of articles in each pile is varied.
  • the container magazine (for example, located under the aforementioned container infeed line as described in the Italian patent application No.3357/80) where the containers are housed, in flat tubular state, consists basically of two sloping bars and two angles, on the outside of the bars. When the number of articles in each pile is varied, it is necessary to select a suitable container size and adjust the mutual distance between the said angles, this adjustment being still today carried out manually by the operator.
  • the container infeed line comprises, amongst other things: a longitudinal track serving both to support the containers and guide the bottoms thereof; means (such as: pegs of at least two chains) for transferring the containers from the insertion station to an outfeed station; two longitudinal bars, located over the aforementioned track and serving to guide the containers moving along underneath.
  • the height of the said bars above the track is adjusted by suitable means whenever it is necessary to change the size of the parallelepiped containers (or cases) obtained by "erecting" the flat tubular container blanks.
  • the said devices consist of hand-operated mechanical means placed beside and/or above the conveyor: the problem with these is that they obstruct assembly, setup and maintenance operations on the lines.
  • the electromechanical means just referred to consist of a variety of mechanisms of varying complexity located over the conveyor with the result that the difficulties with the traditional solution (that is, hand-operated mechanical devices) are not alleviated but accentuated.
  • the object of this invention is to make available such improvements to an automatic machine for the continuous packing of articles as to centralize the control of the aforementioned hand-operated means, of the aforementioned devices and of the "setting" of the number of articles fed by the magazine to the trays on the article infeed line.
  • the invention envisages suitable electromechanical means inter- faceable with a microprocessor mounted on the machine itself or a microprocessor outside the machine in common with other automatic machines.
  • the invention also envisages that the devices to operate the longitudinal bars be of such shape and form as not to encumber the area above the bars, which constitutes an improvement in that assembly and maintenance operations on the aforementioned lines are facilitated.
  • a further improvement envisaged by the invention is the provision of means to enable the operator to handle the containers at the article insertion station without negatively affecting the full containers downstream that have already gone through the station.
  • an automatic machine for the continuous packing of articles comprising amongst other things: two lines, one for the infeeding of the articles and the other for the infeeding of the containers, coplanar and side by side, in the region of a station where the articles are inserted into the containers; a magazine, located upstream of the article infeed line, designed to feed the trays on the article infeed line with a preset number of articles; means, located in between the said magazine and the insertion station, for detecting the number of articles present in each tray, the said means being movable vertically; a second magazine for housing the containers in flat tubular state and located under the container infeed line and usptream thereof; a device between the second magazine and the article infeed line designed to transform the containers from flat tubular blanks into parallelepiped containers; at .least two longitudinal bars, placed over the aforementioned container infeed line, for locating and guiding the containers underneath sliding on a longitudinal track under the action of drive means; a device for the linear adjustment of
  • each longitudinal bar consists of two segments, one fixed and one movable, hinged to each olher, the said movable segment, which is located at the insertion station, being movable vertically between two extreme points and adjustable when it is at the bottom position so that its alignment in relation to the fixed segment can be adjusted.
  • means 1 and 2 indicate two infeed lines, the former for the infeeding of the articles to be packed 3 and the latter for the infeeding of the cases (or continers) 4.
  • the two lines are coplanar and side by side in the region of an station S.
  • Line 1 is made up of a number of trays 5 (translating through H), adjustable in width, into each of which a magazine of known kind (and therefore named generically) discharges a preset quantity (number) of the said articles 3.
  • the means operating the magazine (not illustrated) must therefore be "set” for the required number of articles: the setting is controlled through a centralized microprocessor 100 ( Figure 8).
  • the lines 1 and 2 run at the same speed, which is also the speed at which the push-rods 7 move, the said push-rods being movable also perpendicularly to direction H so as to push the-pile of articles 3 into cases 4.
  • Sensors 8, 12, 14, and 15 and motor 13a are controlled by microprocessor 100.
  • Sensor 8 detects the presence of a preset number of articles 3 in trays 5. If the number of articles in a tray is less than the preset number, sensor 8 detects the anomaly. If the number is greater than the preset number, sensor 8 intercepts the top article of the pile and gives an "O.K.” signal which is in fact wrong; this is picked up (and the signal cancelled) by sensor 12 when movable element 9 rotates as a result of the lifting of sensor 8 consequent on its having intercepted the top article.
  • Magazine 16 which houses containers 4 in flat tubular state, is located upstream of the line 2, under station S ( Figure 6b).
  • a suitable device 17 (such as defended in Italian patent application No.3357A/80) "erects" the blanks to form cases (of parallelepipedal shape, for example) and transfers them to line 2.
  • the magazine 16 is carried on a stem 18, driven by a motor, 20, through electromechanical means 19 which impart vertical translational motion through Fl, F2; a limit sensor '21 detects the "zero" of the stroke of stem 18, while another sensor,.22, “gauges” the fractions of a revolution of the drive shaft 20.
  • Motor 20 and and sensors 21 and 22 depend on microprocessor 100.
  • the magazine 16 has two oblique bars 23 and two sides 24a and 24b, parallel to the bars and freely supported by a crossbar 25 ( Figure 6a).
  • the aforementioned sides are moved in directions K1, K2 by electromechanical means 26 and 27 driven by motors 26a amd 27a.
  • Means 26 and 27 are associated to sensor pairs 28a, 28b and 29a, 29b.
  • Sensors 28a and 29a define the "zero" of the slides of the associated slides 24a and 24b, while the remaining sensors 28b and 29b, "gauge” the fractions of a revolution of the drive shafts of motors 26a and 27a respectively.
  • Sensors 28 a and b and 29 a and b, as well as motors 26a and 27a, are controlled by microprocessor 100.
  • the line 2 for the infeeding of cases 4 comprises, amongst other things, a longitudinal track 30 with longitudinal grooves which pegs 31 slide in, the said pegs being fastened to chains 31a and equally spaced to form receptacles 32 for the containers.
  • Track 30 serves to support and guide the bottoms of cases 4, while the tops thereof are guided by two longitudinal bars 34 ( Figure 3).
  • Bars 34 are cantilevered to four crosspieces, 35a, 35b, 35c and 35d, facing the outside of the line and moved up and down by electromechanical means 36 a,b,c,d.
  • 37 0 indicates an internally threaded sleeve guided axially by structure 38 of the machine.
  • a threaded stem 39 is screwed coaxially to the said sleeve 37 in such a way as to be prevented from moving vertically but carried in rotation by electromechanical means 79 driven by motor 40 (or manually by means of a knob, 39a).
  • the "zero" of the stroke of the sleeve is defined by a limit sensor 41, while another sensor, 42, "gauges" the fractions of a revolution of the motor 40.
  • sprocket 43 (splined to stem 39) and toothed belt 44 drives the electromechanical unit 36b which is the same as that described above, is linked to sensors 41 and 42 and driven by the aforementioned motor 40.
  • the unit 36c is similar to units 36a and b and is provided with a motor, 65, and sensors 46 and 47 ( Figure 8).
  • the electromechanical unit 36d, associated arm 35d, has a bracket 48 containing suitable means for transmitting motion, not illustrated, driven as described above by motor 65.
  • the said unit is linked to sensors 46 and 47 and is driven by motor 65.
  • Motors 40 and 65, as well as sensors 41, 42 and 46, 47 are controlled by microprocessor 100.
  • units 36a, b, c, and d are located under and to one side of line 2 and that electromechanical means 79, with associated motors 40 and 65 are located in the bottom section of structure 38.
  • electromechanical means 79, with associated motors 40 and 65 are located in the bottom section of structure 38.
  • the longitudinal bars consist each of two segments, 34a and 34b, one fixed and one movable, respectively, hinged together by means 81, the movable segment being located at the insertion station, S.
  • each push rod 7, actuated in synchrony with lines 1 and 2 inserts a preset number of articles 3 into the corresponding case 4 from the open end, 4a, of the case.
  • 82c indicates a portion of the aforementioned fixed segment 34a and 82d a space in movable segment 34b.
  • the top 83 of the said portion 82c matches with a rest of the said space 82d.
  • the movable segment has an associated block 86 with a ball 87 pushed out partially from one end by spring 88.
  • segment 34b When segment 34b is in "lowered" position, the said ball goes into a socket 89 made in the aforementioned portion 82c of the fixed segment 34a.
  • the lifting action exerted on the segment 34b when the insertion station S is called into operation overcomes the resistance of spring 88, thus enabling the ball 87 to come free of the socket 89.
  • the means just referred to make it quick and easy for the operator to set things right at the insertion station S without negatively interfering with the cases already downstream of the station and waiting for subsequent operations.
  • Another notable advantage is that the movable segment 34b is adjustably mounted to be aligned with the fixed segment 34a. This makes it possible to increase or decrease the pressure of the bars on the cases 4, as necessary, which increases or decreases the "stiffness" of the cases only at the most critical point, i.e., in the region of the insertion station, without affecting the smoothness or timing accuracy of the rest of the line.
  • the movable segments 1b may also be operated by electromechanical, pneumatic or other similar means, the said means being controlled by suitable sensors (not illustrated) designed to detect when the movable segments get jammed.
  • suitable sensors not illustrated
  • the feature just referred to is particularly interesting as it permits the movable segments to be lifted automatically and to control their operating means through the aforementioned microprocessor 100.
  • part number 50 indicates the coding unit, located downstream of the station S and designed to stamp a preset combination of numbers and/or figures on the side of each case 4 (after insertion of the articles 3).
  • Unit 50 is carried on a mounting block 51 (which rotates about a vertical axis from a work to a rest position, perpendicular to each other). the said unit 50 being moved up and down by electromechanical means 52 driven by an electric motor 53. In this case too there are a limit sensor (defining the "zero" of the stroke of the mounting block 51), and another sensor 55 for measuring fractions of a revolution of the shaft 56, the turning of which - by known means - transmits the vertical translational movement to the said mounting block. Motor 53, as well as sensors 54 and 55, are connected to microprocessor 100.
  • the improvements to the machine consist of original, machine-mounted mechanisms each operated by an electromechanical means or unit, each of the said electromechanical means or unit having two sensors, one for measuring the fractions of a revolution of the drive shaft - each fraction of a revolution giving rise to a preset displacement of the movable part of the corresponding mechanism - and one stroke limit senson for defining the "zero" reference point of each shaft used by the microprocessor 100 to locate and monitor the drive shafts of the mechanisms.
  • the microprocessor 100 can be used to control several machines, though there is nothing to prevent its being used only for the one machine which the improvements refer to.
  • the size setting (i.e. length x breadth x height of the containers) of the microprocessor 100 is correlated to the number and/or size of the articles to be inserted into the containers.
  • the dimensions of the articles and on these depend the height of sensors 8, magazine 16, bars 34 and coding unit 50 and the spacing of the sides 24 a and b (defining the width of magazine 16).
  • the operator enters in the microprocessor 100 the number of articles to go into each container 4 and the microprocessor accordingly adjusts the aforementioned electromechanical means to suit the size of the corresponding containers.
  • the microprocessor runs in accordance with a preset programme, using the electrical signals sent to it by the displacement detectors and with reference to .the "zero" points defined by the aforementioned limit sensors.
