Definitions

  • the present invention relates to conversion presses.
  • the invention concerns a positioning device for stock shells in conversion presses fit for converting such shells into easy-open covers used as closing ends for drink and food cans and the like, although it is understood that such invention is also applicable to presses for the working stocks of different kinds.
  • Conversion presses for semi-raw shells are known, including fixtures designed for converting such shells into easy-open covers, by virtue of the a tab application that allows the opening of the cover.
  • Known presses generally include a bed supporting lateral uprights on which is fastened, by means of tie rods extending through the uprights, a crown that generally supports the main drive means of the press motion members.
  • Sliding support guides for a ram which supports the tooling of the press upper die shoe, are connected to the uprights.
  • Such conveyor belt generally slides on a seal box in which vacuum has been made, so as to hold the shells positioned in their housings.
  • the shells apart from to be moved longitudinally, require also to be moved in vertical direction for avoiding that the shells crawl on the lower tools during their motion from a station to the following one.
  • the main object of the present invention is therefore to propose a positioning device for stock shells in a conversion press that allows the same to be centered in the seats of the conveyor belt during the shell working cycle.
  • Further object of the present invention is to propose a device of easy realization and reliable operation and maintenance.
  • numeral 30 indicates a device for positioning stock shells 2 in a conversion press 100 of such shells 2 into easy-open covers for drink cans or generally food cans.
  • Such press 100 whose structure and general opoeration are substantially known, is provided with a lower die shoe base 1, substantially horizontal, fixed to a bed of the same press in known manner.
  • Such lower die shoe base 1 is constituted by a lower die shoe plate 1a overlapped by a supporting station plate 1b.
  • the lower die shoe base 1 supports a plurality of lower pressing stations 3, placed consecutively on two lines slightly staggered. It is clear that both the line number and the staggered disposition of aforesaid lower pressing stations 3 is made in this embodiment only as example.
  • the press 100 has also an upper die shoe base 11, substantially horizontal too, which overhangs the lower die shoe base 1, and is constituted by an upper die shoe plate 11a and an upper station plate 11b, fastened thereto. This last support at the bottom a plurality of upper pressing stations 13, placed in axle with the corresponding lower pressing stations 3 and fit to made the progressive conversion of shells 2 into correspondent covers.
  • the upper die shoe base is driven in vertical direction between a lifted position A of shells 2 movement, in which the upper pressing stations 13 are lifted from lower pressing stations 3 and a lowered position B of the same shells 2 conversion, in which the upper pressing stations 13 are in contact with lower pressing stations 3.
  • the press 100 has also a continuous belt 6 of the aforesaid shells 2 movement, driven step by step, by known members of the same press 100, according to a feed direction W (figure 1), in phase relationship with the operation of said upper die shoe base 11.
  • the upper branch 6a of the continuous belt 6 overhangs the lower pressing stations 3 and is designed for carrying the shells 2 in sequence through the following pressing stations 3 of the press 100.
  • a plurality of pushers 20 is associated with the upper die shoe base 11, at both sides of each aforesaid upper pressing stations 13. Such pushers 20 are movable together with the upper die shoe base 11, and are designed to interest the continuous belt 6, when the same base is in the lowered position B, for forcing the lowering of the continuous belt 6 and for setting in such a way each of the shells 2 at the corresponding lower pressing station 3.
  • the positioning device 30 of the invention is substantially associated with the lower die shoe base 1.
  • It comprises firstly a fixed frame 31, assembled on the lower station plate 1, perimetrically to the of lower pressing stations 3.
  • the plates 33 include a first plate 43, a median plate 53, consecutive thereto, and a terminal plate 63, placed after the median plate 53 in comparison with said feed direction W of the shells 2.
  • the median 53 and terminal 63 plates are besides spaced, for allowing the crossing of a tab feeder belt 64, according known ways. This latter is used in correspondence of suitable pressing stations 3,13 for fixing relative tabs 2a to the shells 2.
  • the plates 33 are provided with a plurality of circular housings 33a in correspondence of the lower 3 and upper 13 pressing stations, and of a plurality of slots 33b in correspondence of the pushers 20. They are destined to co-operate with the lower die shoe base 1, the frame 31 and the shells 2 for defining a vacuum box 34.
  • the belt 6 therefore slides substantially in the upper part of the aforesaid vacuum box 34. This last is kept continually in depression by not illustrated vacuum-operated means.
  • elastic striker means 35 are associated with the lower die shoe base 1, fit to support the upper branch 6a of the continuous belt 6. They can slide vertically, in phase relationship with the operation of the upper die shoe base 13, between a lifted position C (see figure 3) and a lowered position D (figure 4), in which said shells 2 are stopped on the respective lower pressing stations 3.
  • the aforesaid elastic striker means 35 are constituted by a plurality of longitudinal bars 36, substantially horizontal and parallel, extending for part of lower pressing stations extension 3.
  • two or more longitudinal bars 36 can be placed consecutively on the same axle. They are associated at the bottom to correspondent elastic reaction members 37, embedded in said lower die shoe base 1.
  • a plurality of splined blocks 38 placed at the top of said longitudinal bars 36, drive these latter during their vertical translation between the lifted C and lowered D positions.
  • the vacuum box 34 is constantly kept in depression, in such a way that the shells 2 are always kept in the ideal pressing position.
  • the upper die shoe base 11 When the shells 2 are positioned above the respective pressing stations 3,13, the upper die shoe base 11 is brought from the lifted position A to the lowered B one. During such excursion, the pushers 20 pass through the slots 33b of the plates 33, and contact with the continuous belt 6 placed thereunder. Therefore the pushers 20 forces the longitudinal bars 36 into a down translation, overcoming the elastic reaction of the axial springs 37, until said longitudinal bars 36 reach their lowered position D.
  • the upper die shoe base 11 After a prefixed time period, the upper die shoe base 11 is brought into its lifted position A, so restoring the initial conditions.
  • the main advantage of the present invention is therefore to provide a stock shells positioning device for conversion presses allowing the same shells to remain centered in the seats of the conveyor belt during the working cycle of the same shells, and reducing the number of parts in movement.
  • Further advantage of the present invention is to provide a device of easy realization and reliable operation and maintenance.
