Definitions

  • the invention concerns improvements to machines for cone-shaping and flanging of aerosol cans and similar, comprising means of vertical movement for conveyor feed belts, in addition to those of lateral movement; double means of control for the so-called feed lungs, one of them independent, of traditional type, the other directly derived from the cone-shaping machine; universal comb with shims calibrated for adjustment of the feed belt-loading drum transfer with cans of different types; loading and discharge drums with coaxial suction means and rapid means of change and safety control sensors; pliers-closing and can-ejecting devices with fast controls, derived directly from the main movement; for complete or partial fast replacement of the rotating pliers-holder and the die and spindle-holder; devices to check the axial position and positioning of the dies and spindles and means of interface for connection of all the controls of the cone-shaping machine and line processors.
  • Machines have been provided heretofore for cone-shaping and flanging an end portion of an open ended can body.
  • U.S.-A-3 913 366 discloses a machine for necking-in an end portion of a can body according to the pre-characterising part of claim 1 comprising a rotatable turret carrying a plurality of circumferentially spaced can body receiving and clamping means; a corresponding spindle on said turret for each clamping means and having a longitudinal spindle axis substantially coincidental with the longitudinal axis of a can body clamped in the corresponding can body receiving and clamping means; means supporting the spindle for rotation relative to the turret and axial displacement relative to the turret with respect to the end portion of the can body clamped in said corresponding clamping means; said spindle having inner and outer forming rolls supported thereon for rotation about roll axes and for relative displacement of said rolls toward and away from one another, said roll axes being spaced from one another and from the spindle axis, the inner and outer rolls in the extended position of the spindle receiving the end portion of
  • Machines are also known for the cone-shaping of cans like the aerosol type consist in a central body, on which a pliers-holder with intermittent rotation is applied, which is aligned to a plate, with alternate forward and backward movement, on which the dies and tools for processing are applied.
  • the cans to be treated are collected by a drum, which aligns them with a loading station, from which they are pushed on the seats present in each station of the rotating holder for grippers.
  • a loading station from which they are pushed on the seats present in each station of the rotating holder for grippers.
  • each station means are present which bind the cans to keep them in the same position throughout all processing phases, which succeed one another as the rotating holder gradually turns intermittently, aligning itself at each pitch to the cone-shaping dies or to the tools assembled in sequence on the plate with alternate motion.
  • the operating machines are fitted with means of control, applied directly on the spindle and/or die-holder.
  • Said means of control which mainly consist of proximity sensors, are placed in a position where they detect the exact backward movement of the equipment present on the die-holder, after their active phase.
  • each time production is varied, i.e. each time there is a switch from processing of one type of can to that of a can with different diameter and/or shape, it is necessary to dismantle all the tools, spindles and fixing means of the rotating holder and the plate with alternate motion, completely stopping both the machine and the auxiliary means, such as the accumulator.
  • the above dragging movement may be produced by the friction arising between the central guide die and the deformed collar of the cans, or between said die and the possible burrs present on the edges of the collars, which lock together the parts in contact the moment they should separate for the start of the return stroke of the equipment.
  • the friction between the parts may be stronger than the grip of the rear grippers which grip and hold in position the bottoms of the cans.
  • a machine for come-shaping and trimming the open end of a can body comprising: a conveyor feed belt; means for feeding the can bodies from an accumulator to the conveyor belt; a rotatable loading drum provided with circumferentially spaced seats for the can bodies; means for guiding each can body leaving the conveyor belt onto a seat of the loading drum; a rotatable holder; a plurality of circumferentially spaced automatically closing grippers carried by said holder for clamping the outer surface of the can bodies, means for closing and opening the grippers and ejecting the cans; a plate carrying dies and spindles having its longitudinal axis substantially coincidental with the longitudinal axis of the can body clamped in the corresponding gripper; a rotatable discharge drum receiving the finished can bodies ejected from the gripper; a discharge belt for receiving the can bodies released from the discharge drum; means for intermittently rotating the holder,
  • the conveyor feed belt is capable of lowering itself and rotating, to give access to the machine, without imposing modifications to the surrounding parts, like the feed accumulator;
  • the secondary power take-off favours the loading phases of the accumulator even when the machine is at a standstill to fit the necessary equipment at each new processing cycle;
  • the universal guides favour the feed of the loading drum, according to the type and size of the cans to be treated;
  • the coupling means of the loading and discharge drums, the closing and opening means of the grippers and position control are automatic and regulated by control systems which check their position and stop the machines at each minimum irregularity;
  • the die-holders are simpler as they are without positioning control devices and the relevant position-means;
  • the control means are positioned near the base of the seats in which the objects to be processed are positioned; their intervention is simultaneous and directly derived from the grip action of the grippers;
  • the advantages of the present invention mainly consist in the fact that all the means are designed to cut intervention times, to cut the dead times required to set up the necessary equipment at each processing cycle, to eliminate or limit the causes of accidental stopping, to facilitate the feed, loading, discharge, regulation and programming operations involved in the processing cycles of cans of different sizes; the means of control are also of simple, effective construction and operation; their action remains constant throughout the entire processing cycle of each object, guaranteeing a perfect positioning check on the objects in processing and a safe, immediate intervention at each possible displacement, even minimum, of same: the setting up and/or replacement of the equipment (dies and tools) applied to the rotators are simpler and faster.
  • FIG. 1 show a machine (2) for the cone-shaping and flanging of aerosol cans, or similar, comprising, in sequence, a conveyor belt (5) with which the cans (16) to be processed, which come from a feed accumulator, not shown, are sent to a loading station, consisting of a rotating loading drum (11). From the drum (11) the cans (16) are loaded, one at a time, in the can grippers (39) applied on the rotating holder (38).
  • each intermittent rotating feed of the rotating holder (38) corresponds an identical intermittent rotating feed of the drum (11), so that a can (16) is inserted in each empty set of grippers (39) aligned to the loading station.
  • each can (16) gripped in grippers (39) rotates with the holder (38), is sequentially aligned with all die-holder stations (45) and/or spindle-holder stations (65) present on the plate with alternate motion (53), and is submitted to the corresponding processing phases.
  • the grippers (39) open and the finished cans (16') are ejected and sent to a rotating discharge drum (71), which collects and deposits them on a discharge conveyor belt (72).
  • a first improvement of the cone-shaping machine consists in a device, shown in figures 3 and 4, composed of a hydraulic or pneumatic piston (1), applied on the side (73) of the cone-shaping machine (2), which supports the bracket (3) on which is supported, in (4), the conveyor belt (5) which feed the cans (16).
  • the conveyor belt (5) is thus capable of making vertical movements in the direction of the arrow (74), besides rotating horizontally round its support (4) in the direction of the arrow (75), pushed by the piston (6). This operation of displacement is necessary to permit free access to the front part (7) of the machine (2) to perform standard maintenance operations, or similar.
  • the same belt (5), at its ends (8), has been equipped with a universal guide (9), comprising interchangeable calibrated shims (10) through which it is possible to adjust the position of the cans (16), according to their diameter, in order to facilitate and guarantee their correct insertion on the loading drum (11).
  • the guide (9) is substantially applied on the discharge side (8) of the belt (5), so that, when a can (16) is in arrival, it is conveyed towards one of the housings (12) present on the loading drum (11), according to a trajectory that facilitates correct insertion.
  • the guide is suitably regulated to guarantee the abovementioned trajectory; this is easily obtained, slackening the locking means (13) and replacing the calibrated shims (10) with those corresponding to the required size.
  • a second auxiliary control of the accumulator has been constructed, not shown, derived from a power take-off (21) located on the side of the machine.
  • the motorization of the auxiliary members of the cone-shaping machine (2) is controlled by a pneumatic coupling unit (14) with different operating positions, located inside the machine.
  • a basic condition is that the toothed coupling (18) is designed to permit the coupling according to a single position of 360°. This is obtained by creating the toothed coupling (18) alternated with different pitches to ensure that the coupling can take place according to only one solution.
  • FIGS. 6 and 7 show the means of control of the loading (11) or discharge drum (71).
  • the coupling suction of the cans (16) takes place by means of slits(27) made in the hollow of the seats (12), which are connected to the suction mouth (28) of the vacuum pump, through the tubular chamber (29) and the coaxial pipe (30), with spans (31) coaxial to the same drum.
  • a torque limiter (32) with the possibility of a movement in axial direction, under force, of some millimetres.
  • the limiter (32) is stiffly connected to the front end of the central rod (33), whose rear end is supported by an elastic means (34). To the elastic means (34) is aligned a sensor (35) and therefore, at each action or intervention of the load limiter (32), or at each movement in axial direction of the central rod (33), the sensor intervenes causing the immediate stop of the machine.
  • the control sensor (35) also has the function of coaxial safety control to permit the change of drums (11,71) without the need to make electrical connections. Through the front ring nut (37), self-locking, with manual tightening without the aid of any tool, it is also possible to make a rapid replacement of the abovementioned drums (11,71).
  • the union (40), figure 9, is coaxially assembled to a tubular pipe (41), connected to a compressed air intake, not shown, and controlled, with alternate motion, by means of a device with connecting rod-crank (42) which receives the command, suitably ratioed, from the central control (43) which causes the alternate forward and backward motion of the holder (44) on which is applied the plate (43) carrying dies (45), and spindles (65).
  • the mechanical controls (42) described above have the advantage over those presently in use of being derived from the central control (43) and of having a decidedly higher intervention speed than can presently be obtained with servo-assisted means, so high that it reaches, in equal situations, a working time of feed or discharge of air from the grippers (39) almost three times greater, to the advantage of the rise of productivity, or of possible strokes per minute.
  • Figure 14 shows an illustrative example of means of grip and control for the positioning of cans (16), of aerosol type, submitted to multiple sequential processings of cone-shaping and processing of the edges, on operating machines (2), comprising, for each station of the intermittent rotating holder (38) and at the hole of each seat (102) containing the rear ends of cans (16) to be processed, a rear pushing means (104) which acts on the rear (105) of the ejecting piston (106).
  • the pushing means (104) is preferably, but not limitatively, controlled simultaneously to the peripheral grippers (107) which act circumferentially at the lower end of the cans (16) being processed.
  • the anular elastic means (107), compressed and guided also to the rear by the small piston (114), can only expand towards the inside of the seat (102), uniting around the lower circumferential peripheral end of the can (16).
  • the elastic anular means (107) act circumferentially on the end of the can (16), forming the pliers for same, a small part of compressed air passes through the pipes (111 ⁇ ) and (111 ⁇ ) and acts on the rear surface (116) of the pushing means (104), pushing it towards the outside.
  • the pressure applied on said rear surface (116) is such, and sufficient, that it overcomes the resistance of the return spring (117) of the ejector piston (106) and pushes same into simple contact with the surface of the bottom (108) of the can (16).
  • the ejector piston (106) resting on the bottom (108) of the can (16), its rear end (118) is perfectly aligned with a proximity sensor (119), composed, for example, of a microswitch.
  • the cans (16) remain in position, locked by the grippers (107).
  • the ejector piston (106) calls back its end to which it is connected by the rod (52), moving it from the alignment position with the proximity sensor (119).
  • the corresponding sensors (119) present in each work station cause the immediate stop of the operating machine (2), signalling also the station in which the faulty condition has been found.
  • the proximity sensors (119) may be replaced by other similar devices of electromechanical or mechanical type, for example.
  • the immediate break of the processing cycle and location of the fault consent a fast, immediate intervention by the operator to restore standard operating conditions and eliminate the cause of the break, without even partially damaging production.
  • a pusher acts on the pin (112) of the valve (46), opening its seat and discharging the compressed air contained in it.
  • the pliers (107) slacken their grip and the ejector piston (106) is pushed forward by a second device with connecting rod-crank (42) acting on the rear end (118) of the rod (52) until it takes it to the position (124), indicated in dotted line.
  • the can (16) is thus pushed outside its seat (102) and discharged by the operating machine (2) on the discharge drum (71).
  • the pneumatic control of the small piston (114) which compresses the elastic anular means (107) and the pneumatic control of the pusher (104) and relevant circuits (111), (111') and (111") may be independent and/or driven with different fluids at equal or different pressures.
  • the same action of the pusher (104) may also be produced with other suitable means, e.g. opposite electromagnetic fields or electromagnets and similar, and the same pusher (104), constructed as independent element, may be formed in another way, like a circular crown, for example, integral to the upper end of the control rod (52) and adjacent to the rear (105) of the ejector piston (106).
  • suitable means e.g. opposite electromagnetic fields or electromagnets and similar
  • the same pusher (104), constructed as independent element may be formed in another way, like a circular crown, for example, integral to the upper end of the control rod (52) and adjacent to the rear (105) of the ejector piston (106).
  • Figure 11 shows a partial cross-section of a cone-shaping machine (2) on which a holder (38) carrying grippers (39), and a plate (53) carrying dies (45,45') are applied.
  • the rotating holder (38) is put into intermittent rotation by the members (54) of substantially traditional type, on which it is applied, while the plate (53) is applied to a support (44), suitably connected to the central body (43) of control of the alternate forward and backward movement.
  • both the holder (38) and plate (53) are mounted on the corresponding supporting structures to simplify their disassembling and replacement.
  • the rotating holder (38) is substantially fixed to the rotation members (54) by an anular pressure-body (55), which is held in position by a handle (56) which presses on the same anular body (55) a metal element with low module of elasticity (63), like copper.
  • the plate (53) is held in position on the support (44) by means of an anular pressure-body (57), held in position by a handle (58), also pressing another metal element (64) with low module of elasticity.
  • the rotating holder (38) and plate (53) can thus be unthreaded simply and extremely quickly to be replaced with another completely identical holder or plate, but on which a different type of grippers (39), dies and/or spindles are applied, for processing of cans (16) of different type and gauge.
  • Figure 1 clearly shows the way in which a plate (53) with all its dies (45) and its motorized or unmotorized spindles (65) can be removed and replaced with another complete plate (53'). With the plate (53) dismantled and before its replacement, it is possible, in similar way, to replace the rotating holder (38). To facilitate this operation, the machine (2) is preferably fitted with a small upper pulley block (66).
  • said plates (53) and said rotating holders (38) can also be constructed with modular sectors, which, through suitable means of connection and separation, may be interchangeable with corresponding means.
  • the total time of preparation of a machine for a completely new process is reduced to about 15 minutes, time in which the loading and discharge drums (11 and 71), and the shims (10) of transfer from the belt to said drums (11) can be replaced, and the accumulator of the machine is filled.
  • microswitch (67) substantially in contact, during standard operation, with the thrust bearing (68) integral to the central control (43).
  • the support (44) tends to move away from its position with respect to the control (43).
  • the microswitch (67) comes away from the abovementioned thrust bearing (68), causing the immediate stop of the machine, safeguarding its components and the production in course.
  • Figures 12 and 13 show, finally, some nonion type regulating means (69) and (70) applied, respectively, to the support (44) of the plates with alternate movement (53) and directly to the dies (45) and spindles (65).
  • the regulating means (69) consents a general positioning of all dies (45) and spindles (65) with respect to the corresponding grippers (39) applied on the rotating holder (38); the regulating means (70) has the function of regulating the positioning of each die and each single tool for the processings of the edges of the cans (16), and for compensation of their wear.
  • the positioning device of the pressing plate(53) holding the equipment, which approaches the grippers (39) during cone-shaping, may be constructed by hand, as mentioned, and by motorization, like the part of regulation of the position of the dies and tool spindles applied in the last stations of the plate (53) for the finishing processes of the edges of the cans (16), or of the mouth, after cone-shaping.
