Definitions

  • the present invention relates to an all-mechanical linkage providing for simultaneous and synchronized operation of the feed device and netting station in automatic equipment for net-packing containers of fruit and vegetable produce.
  • the prior art embraces automatic equipment by which fruit and vegetable produce packed in containers are wrapped in net, substantially comprising: -an elongated tube enveloped externally by a long and tightly bunched tubular net serving ultimately to ensheath containers previously filled with fruit and/or vegetable produce, which are introduced into the tube at one end and fed toward the remaining forward end; -a feed device comprising a longitudinal element guidedly reciprocated inside the ned feed tube and provided with at least one projection designed to register with the containers on one side and propel them toward a netting station located beyond the forwardmost end of the tube; -a guillotine device installed at the netting station, incorporating a pair of fixed elements disposed transversely to the direction of movement of the containers, and a pair of moving elements positioned above and operating in conjunction with the fixed elements, capable of vertical motion in relation thereto between a raised first position, whereby an opening is afforded between the pairs of elements for the passage of the forward end of the longitudinal element, carrying a netted container, and a lowered
  • both the moving guillotine elements of the netting station and the longitudinal element of the feed device are set in motion by rod-and-crank type mechanism suitably synchronized one with the other in such a way as to avoid any mechanical contact between moving parts during those operating steps which involve a geometrical intersection of the relative trajectories.
  • the velocity of the longitudinal element of the feed device is conditioned by factors dependent on the characteristics of the produce being packed, for instance such as the greater or lesser degree to which containers are filled, hence the risk of losing produce, in particular due to inertia in the initial stages of the feed movement and in cases where the produce projects above the side of the container.
  • factors dependent on the characteristics of the produce being packed for instance such as the greater or lesser degree to which containers are filled, hence the risk of losing produce, in particular due to inertia in the initial stages of the feed movement and in cases where the produce projects above the side of the container.
  • This further movement is characterized by being continually contrary to the motion of the longitudinal element, with the clear end in view of increasing the effective velocity of the longitudinal element in relation to the moving parts of the netting station, and doing so without affecting the optimum absolute feed rate obtainable for the containers.
  • the object of the present invention is to overcome the various drawbacks described above by the adoption of an entirely mechanical linkage as characterized in the appended claims, designed to ensure simultaneous and synchronized operation of the feed device and netting station by which containers filled with fruit and vegetable produce are wrapped in automatic net-packing equipment.
  • the moving elements of the netting station are set in motion by a particular epicyclic type of rod and crank mechanism which, synchronized in operation with the transmission components of the feed device, invests the moving elements of the netting station and the longitudinal element of the feed device with movement at variable velocity along their relative trajectories in such a way as to obtain an optimum combination of the relative mutual velocities at each instant.
  • this advantageous combination of operating velocities also permits of dispensing with reciprocation of the netting station along the trajectory of the longitudinal element.
  • the advantages afforded by the present invention are essentially those of: -enabling the embodiment of automatic equipment in which all movement derives from an all-mechanical linkage, hence great reliability in terms of safety from any malfunction attributable to unwarranted contact between moving parts; -obtaining equipment of simpler design, driven by a single prime mover and decidedly more competitive from the standpoint of economy; -securing a more favourable interrelation between the velocities of the various moving parts, and by extension, particularly high hourly output rates.
  • 1 denotes automatic equipment for packing containers 4 of fruit and vegetable produce in a net covering, comprising: -a tube 2, enveloped externally by a long and tightly bunched tubular net 3 of which the forward end 3a is sealed in readiness to ensheath and wrap single containers 4 filled previously with fruit or vegetable produce and fed along the inside of the tube 2 toward the forward end 3a of the net 3; -a feed device 5 consisting substantially in a longitudinal element 6 designed to interact with a netting station 8 situated beyond the forwardmost end 2a of the tube 2, which is furnished at its forward end 6a with at least one spring-loaded projection 7 directed upwards and designed to register with the rear of the single containers 4, inserted into the tube 2 from the rear end 2p, and propel them forward together with the ensheathing stretch of net 3 toward the netting station 8.
  • This same feed device 5 is also capable of guided reciprocating movement internally of the net feed tube 2 between a retracted limit position, in which the forward end 6a of the longitudinal element 6 is encompassed by the feed tube 2 and completely clear of the netting station 8, and an extended limit position in which the projection 7 carried by the forward end 6a of the longitudinal element 6 lies beyond the netting station 8.
  • the netting station 8 incorporates a guillotine device 9 comprising a pair of fixed elements 10 disposed transversely to the feed direction followed by the containers 4, parallel one with another and set apart at a distance such as will permit of interacting with a second, moving pair of elements 11; more exactly, these elements 11 are positioned above and operated in conjunction with the fixed elements 10, moving in parallel planes marginally offset from those of the latter.
  • a guillotine device 9 comprising a pair of fixed elements 10 disposed transversely to the feed direction followed by the containers 4, parallel one with another and set apart at a distance such as will permit of interacting with a second, moving pair of elements 11; more exactly, these elements 11 are positioned above and operated in conjunction with the fixed elements 10, moving in parallel planes marginally offset from those of the latter.
  • the moving elements 11 are slidably supported by upright columns 13 and capable thus of traversing vertically between a raised portion (see fig 1), in which the pairs of fixed and moving elements 10 and 11 afford an opening 12a that freely allows passage of the forward end 6a of the longitudinal element 6 of the feed device carrying a container 4 ensheathed by its net 3, and a lowered position (see fig 3) in which the opening 12b between the moving elements 11 and the fixed elements 10 is reduced in size, and just sufficient to ensure that the stretch 3a of net 3 immediately following the container 4 is retained, correctly positioned, once the forward end 6a of the longitudinal element 6 has been retracted from the netting station 8.
  • Automatic net-packing equipment 1 further comprises an entirely mechanical linkage 14, which in turn comprises a rod-and-crank mechanism 14a serving to bring about operation of the guillotine device 9, and means 14b by which the operation of the rod-and-crank mechanism 14a itself is synchronized with that of the feed device 5.
  • the mechanism denoted 14a comprises: -a rod 18, connected pivotably at one end 18b with the moving elements 11 of the netting station 8; -a power driven rotating crank element 175 to which the rod 18 is rotatably coupled by its remaining end 18a in such a way that this same end 18a can be made to describe a controlled trajectory deriving from the rotation of the crank element.
  • the crank element 175 comprises: -a fixed disk 15, rigidly associated with the main frame 1a of the automatic net-packing equipment 1; -a moving disk 16, in peripheral contact with and exhibiting the same diameter as the fixed disk 15; -a power driven revolving crank 17, of which one end 17a is coupled rotatably to the fixed disk 15 at its axis of symmetry, and the remaining end 17b to the axis of rotation of the moving disk 16, in such a way that the moving disk 16 can be made to roll around the fixed disk 15 and rotate about its own axis at one and the same time.
  • the end 18a of the rod 18 With the relative end 18a of the rod 18 connected rotatably to the moving disk 16 at a point near to its periphery, the end 18a in question is obliged to follow an epicyclic trajectory (or epitrochoid, in the particular instance illustrated) occurring simultaneously with and dictated by the orbit of the moving disk 16 around the fixed disk 15.
  • an epicyclic trajectory or epitrochoid, in the particular instance illustrated
  • the rod-and-crank mechanism 14a thus described permits of reciprocating the moving elements 11 of the netting station 8 along their columns 13 at a variable velocity, which, departing from the fully raised position of the elements 11 and approaching the fixed elements 10, decreases gradually from a maximum initial value to a minimum, reached around the middle of the relative approach trajectory, while at the same moment the longitudinal element 6 of the feed device retracts at maximum velocity through the netting station 8 and into the tube 2.
  • the velocity picks up and increases progressively.
  • the elements 11 having duly reversed their direction of movement and begun the reascent to the initial raised position, the forward end 6a of the longitudinal element 6 will pass through the netting station B at maximum feed velocity carrying a further container for netting.
  • Means 14b by which the rod-and-crank mechanism 14a is synchronized with the feed device 5 comprise: -a power driven revolving crank 19, of which one end 19a is anchored pivotably to the frame 1a of the automatic net-packing equipment 1; -a first rod 20 coupled rotatably to the remaining end 19b of the revolving crank 19; -an oscillating element 21 affording three ends denoted 21a, 21b and 21c, of which a first end 21a is pivotably anchored to the main frame 1a of the equipment 1 and a second end 21b pivotably coupled to the first rod 20, thereby enabling receipt of the motion required to produce oscillation about the pivot of the first end 21a; -a second rod 22, of which one end 22a is coupled pivotably to the third end 21c of the oscillating element 21 and the remaining end 22b connected to the longitudinal element 6 of the feed device 5.
  • the movement of the means 14b thus embodies is synchronized with that of the feed device 5 in such a way that maximum velocity of the longitudinal element 6 is generated during passage of its forward end 6a through the netting station 8 in each direction.
  • the passages in question are, respectively, that in which the single container 4 is carried forward by the longitudinal element 6 to be netted, and that in which the element 6 retracts into the feed tube 2 following separation from the container 4 beyond the netting station 8.
  • Both the rod-and-crank mechanism 14a and the feed synchronizing means 14b are set in motion by a single drive 23, which in the preferred embodiment illustrated in the drawings consists substantially in a geared motor 23a to which both the crank 19 of the synchronizing means 14b and the crank 17 of the guillotine mechanism 14a are coupled mechanically, in the latter instance by way of a conventional belt transmission 23b.
  • the rod-and-crank mechanism 14a and the means 14b by which synchronization with the feed device 5 is achieved are mutually and mechanically interlocked and interdependent, the movement of the one being dictated by that of the other.
  • Fig 2 illustrates a configuration of the linkage 14 in which the longitudinal element 6 of the feed device 5 is fully retracted in relation to the net feed tube 2.
  • the forward end 6a of the element is entirely encompassed by the forwardmost end 2a of the tube 2, carrying a container 4 engaged from the rear by the projection 7 and ready for transfer to the netting station 8.
  • the guillotine device 9 is positioned with its moving elements 11 lowered against the fixed elements 10 and engaged currently in securing a stretch of net immediately to the rear of a container 4 already wrapped and moving away beyond the station 8.
  • the moving elements 11 reascend to their raised position at progressively increasing velocity, and at the same time, the longitudinal element 6 advances toward the netting station, likewise at a progressively increasing velocity.
  • an opening 12a is created of height sufficient to allow passage of a container 4 to the netting station 8, ensheathed in its net 3 and carried by the forward end 6a of the longitudinal element 6, which at this stage will be moving at maximum feed velocity.
  • the raised position has been reached and the moving elements 11 are seen descending toward the fixed elements 10 in the reverse direction, decelerating gradually from the velocity registering at the initial stage of the descent trajectory; in the particular instance of fig 5, the moving elements 11 are shown completing near to half the descent trajectory and approaching their minimum velocity.
  • the forward end 6a of the longitudinal element 6 will have reached its travel limit beyond the netting station 8 and now, moving in the reverse direction, retracts at increasing velocity toward the net feed tube 2 leaving the container 4 on the far side; maximum retraction velocity of the longitudinal element 6 is gained on passing through the netting station 8 at the moment in which the velocity of the moving elements 11 of the guillotine device 9 is at minimum.
