Definitions

  • Packaging machines which process web-shaped packaging material into satchets or bags which are already filled with an article are known per se. They firstly convert the web into a tube, either by folding the web lengthwise and sealing its margins together or by sealing together the margins of two webs, thereafter they fill the tube so formed and divide its contents by transversal seals. In this way, from'said packaging machines a chain of satchetlike containers will issue, which are interconnected by said transversal seals.
  • each transversal seal forms the lower sealing seam of one container and the lower half of each transversal seal forms the upper seam of the successive one.
  • these satchets are molded into a prismatic shape.
  • the webs of packaging material are precreased and after their issue from the packaging machine the satchets are passed through a forming machine, where they are given the desired shape by folding their walls along the precreased lines.
  • a container molding device which is extremely simple of construction, is comparatively inexpensive and combines its molding function with that of conveying and discharging the formed containers.
  • a plurality of U-shaped trays is mounted at intervals on an intermittently moving conveyor, each tray forming the bottom, the front and the rear wall (as seen in the sense of its movement) of a prismatic mold and is passed by said conveyor between two movable lateral mold plates and under an upper mold plate, said three plates forming a package molding station.
  • the packages are fed in succession, one by one, into each tray either when it reaches the molding station or upstream of it, while means are provided to stop the conveyor while the container is being shaped into a prismatic package in the molding station and to move a successive tray into said station once this operation is completed on the preceding tray.
  • the trays form not only three walls of the mold, but also serve to retain the container safely during its further travel and to safeguard it during its discharge at the end of the conveyor.
  • the upper mold plate may conveniently consist of two horizontally reciprocable jaws, which when opened, permit to feed through them into the underlying tray the still unformed container issuing from the packaging machine and which, in their closed position, grip the container by its upper transversal seam and simultaneously act, with their flat bottom surfaces, as said upper mold plate.
  • These jaws may also be conformed as cutting jaws, which may combine their gripping action with that of severing the container in the tray from the overlying ones.
  • the movement by which the still unformed container is pressed against the upper mold plate is obtained by rendering the conveyor vertically oscillatable around a pivot away from the molding station, for instance around the shaft of one of its sprockets or pulleys, so that its free end may be lifted, together with the tray in the molding station, to press the container in it against said jaws.
  • FIG. 1 is a schematic lateral view of the embodiment
  • FIG. 2 is a sectional view along the of FIG. 1;
  • FIGS. 3 to 5 are schematic partial views of the forming station of FIG. 1, showing three different operating stages of the embodiment.
  • FIG. 6 is a partial enlarged view of FIG. 2, with the lateral mold plates in their operating position.
  • the conveyor carrying the trays 3 comprises two endless chains 1 and 2, led around two pairs of sprockets 7 and 8.
  • Each tray is U- shaped and formsa bottom wall 5, a front wall 4 and a rear wall 6 (as seen in the direction of the arrow F of FIG. 1) of a mold.
  • the sprockets are journaled in a common support 9 which is oscillatable around the horizontal shaft 10 of the drive sprocket 7.
  • a drive shaft 35' to which is keyed a driving wheel 35 coacting with a star wheel36 (the two acting as a Geneva Drive) imparts, by means of a transmission chain 37 connecting the star wheel with the sprocket 7, a step by step motion to the conveyor, each step bringing a tray 3 into the molding station,
  • a bar 11 is pivoted on one end by a pin 12 to the support 9 in the vicinity of sprocket 8 and, on its other end, is linked to one end of a lever 13 whose other end is pivoted, as by a pin 14, to the frame of the device.
  • a cam follower 16 of lever 13 is pressed by a not shown spring against a cam 15 keyed to the drive shaft 35'.
  • the satchet. molding station of the device comprises the initially mentioned two mold plates 17 and 17' and the two jaws 38 and 39, which, when closed, form the upper mold plate. This molding station is located adjacently to the free end of the conveyor.
  • a second cam 34 keyed to the drive shaft 35' imparts a rocking motion to a bell crank lever 31 fulcrumed at 32 to the frame of the device.
  • Lever 31 is connected by a link 30 to a horizontal stirrup 29, to whose ends are fastened two parallel vertical rods 26 and 26 which are guided in a vertical reciprocating movement through plate 22 which is rigid with the frame.
  • Each rod 26, 26' terminates in a cross member 25, 25' respectively.
  • each cross member is connected by a link 24 and 24 respectively to one end of a lever 19 and 19' respectively, whose other end is pivoted at 20 and 20 respectively to a stationary support 21 and 21 respectively.
  • the other end of each dotted line 11-" cross member 25 and 25' terminates in a pin 27 and 27 respectively, which engages in a curved slot 28 and 28' provided in each stem 18 and 18' respectively of the lateral mold plates 17 and 17.
  • the end of each stem l8, 18' is hinged at 23 and 23 respectively to the lever 19 and 19.
  • the satchets are alreadysevered into distinct packages, they may be fed into a tray 3 either before it reaches the mold station, orelse when it has reached it. However, if the satchets are still connected together, the preferred solution is that indicated in the figures.
  • the molding station of the device is here positioned just under the outlet of the packaging machine, so that the lowermost satchet of a satchet chain descending from the packaging machine passes through the open jaws 38 and 39 into a tray positioned in the molding station.
  • the jaws 38 and 39 are horizontally reciprocable on guides 40 and 41 from an open position shown in FIGS. 1 and 3 to permit the passage of the satchet into the tray, to the closed position shown in FIGS.
  • the height of the forming plates is smaller than the height of the formed package, in order to leave room sufficient for the formation of the ears 51, which result from the vertical and lateral compression of the satchet.
  • These ears 51 may successively be folded and fastened against said sides of the formed container by any known and therefore here not described machinery.
  • FIGS. 1 to also show a clamp formed by two parallel crosspieces 45 and 46, which grip the tube 44 of packaging material immediately above each transversal seal 43. These crosspieces are carried by two pairs of endless chains indicated at 47, 48 and 49, 50, respectively.
  • Such clamps serve to protect the still fresh transversal seals of a satchet from the pressure of the liquid filled into the tube above it, and do not form part of the invention.
  • the mechanism for timing the movement of the jaws 38 and 39 with that of the conveyor and of the mold plates is within the reach of the average expert and is therefore here neither described nor claimed.
  • the operating cycle of the device begins with the opening of jaws 38 and 39, the lowering of the filled and sealed and pre-creased satchet 42 till it is partially received in the underlying tray 3, as shown in FIGS. 1 and 3. Thereafter the free end of the conveyor is lowered to the position shown in FIG. 4, followed by the satchet till the upper seal 43 of the latter reaches the level of jaws 38 and 39. At this point the jaws are closed to grip said upper seal, while their (here not shown) cutting blade severs the satchet from the tube 44 upstream of it.
  • the Geneva motion will snift the tray one step .forward, to bring a successive tray into the molding station, the mold plates will be swung back and lowered, while the conveyor will still remain in its upper position till a successive satchet is introduced into said successive tray. Thereafter a new cycle is started.
  • the conveyor of the device accomplishes various tasks. In fact, it participates not only in the forming of the packages by its rocking motion, but also in the step by step transportation and discharge of the shaped packages. It may also cooperate with a machine for folding and fastening the ears 51 against the sides of the container and with any other machine for inspecting the formed packages prior to their further handling and shipping during their travel from the molding station to the end of the conveyor.
  • a device for forming containers into prismatic packages and to thereafter convey and discharge them comprising:
  • first actuating means to press a container in one of said trays against said upper mold plate by lifting a free end of said conveyor
  • second actuating means positively associated with said first means to lift said lateral mold plates concomitantly with said upward lifting of the conveyor and press them against the two sides of an unformed container;
  • Geneva motion means associated with said first and second means, to stop said conveyor when a tray with an unformed container reaches the location of said mold plates and during said container-molding operation and remove it sucessively from said station to convey another tray to said molding station.
  • a device wherein said conveyor has two pairs of sprockets and said conveyor is oscillatable around a shaft of one of its sprocket pairs and said first means are a cam and lever unit linked to said conveyor to impart to it said oscillating motion.
  • said second means comprise two vertically reciprocable parallel rods, a lever for each rod linked with one end to said rod and pivoted with its other end to a stationary support, a pin on each rod and rigid with it and engaging in a curved slot provided in a stem of each of said lateral mold plates, the end of each stem being hinged to said levers, whereby the upward movement of said rods will lift said lateral mold plates and swing them against the sides of said container, while the downward stroke of said rods will invert the motion of said lateral mold LII said unformed container from those upstream of it.
