    Apparatus for forming a seal between layers of a carton of thermoplastic coated paperboard material and the like wherein the thermoplastic material in the area to be sealed serves as the sealant and is activated to flow by frictional heat generated by a vibration welding horn and is then allowed to cool and set under pressure to form the seal between the layers. The carton first moves to an activating station wherein the layers to be sealed are engaged on opposite surfaces by a vibrating horn and a back-up member (in the form of an anvil or a mandrel) for a time sufficient to activate the thermoplastic material to flow. The carton is then carried to a clamping and sealing station at a different location from the activating station with the thermoplastic material in the activated state. The layers to be sealed with the activated thermoplastic is then engaged on opposite surfaces by a pressure pad and the back-up member for a predetermined period of time to permit the activated thermoplastic to cool and set and form a seal. A holding member extends between the activating and clamping and sealing stations. The holding member overlies the back-up member for engaging the outer surface of the layers to hold the layers together in cooperation with the back-up member when the carton is located at either of the stations or between the stations. The holding member is slotted to permit the horn and pressure pad to engage the outer surface of the layers while the layers are held in the closed position between the holding member and back-up member.

At the input end of each of the closing plates 38 there are mounting flanges k2. The flanges 42 are fastened with bolts k3 to the supporting element C. boxes 1 move from the wide end of the locking groove 39 to the narrow end on the supporting element J, the front 8 and the rear cover wall 7 under the influence of the groove edges 37 are closed (position IV, Fig. 3). Then the rims 1 are moved to the activation unit 5 (position Y, Fig 3). In position V1, the clamping and clamping unit is located, and in position U11, the upper lid of the box 1 assumes the form shown in Fig. 11. The support bracket 7 is equipped with means for activating 1 {s of the thermoplastic material, including a vibrating welding console having a flap Part E with working. , surface 50 (FIG. five). The working surface 50 interacts with the back wall 7 of the cover along the strip 30. The console 48 has a converter 51 for converting electrical energy into mechanical energy. Transducer 51 vibrates console 48 at a predetermined frequency. Under the means for activating thermoplastic-. A support 52 is disposed with a working surface 53. The working surface 53 interacts. with the outer surface of the fastening strip 22. When the working surface 50 of the console 48 interacts with the fastening strip 25 and its outer surface, the thermoplastic covering of the cardboard layers is activated along the strip 30 of FIG. 11 and 12). Console 48 has two transverse channels S4 through which cooling fluid circulates. Above the support 52 parallel to its working surface 53 there is a holder 55 which is made in the form of an elongated plate with a slot 5b located opposite the working surface 50 of the console 48. The holder plate 55 has a curved guide protrusion 57 at one end to guide the packaging layers, to be connected to the gap between the holder 55 and the support 52. The holder 55 has a lever 58 (Fig. 4) with a flange 59 Through the flange 59, bolts 60 pass, fasten (the holder 55. to the mounting plate 61. When the box 1 moves to the position 1U (Fig. 3), s The flap 26 and the fastener strip 25 interact with the guide protrusion 57 causing the fastening strips 22 and 25 and the locking flap 2 to join and move into the gap between the holder 55 and the working surface .53 of the support 52 (FIG. 1). When the fastening strips 22, 25 and the locking flap 26 are inserted under the holder 55, the box assumes the shape of FIG. 10. The outer part of the back wall 7 of the cover, through the slot 5b, interacts with the working surface 50 of the console 8 along the strip 30 (FIG. . 12). The means for forming the seam under the yes has a pressure pad mounted on the bracket 62. The support element 64 of the pressure pad, made in the form of a rod, enters the guide groove b5 of the bracket 62 so that the support element 6 can move reciprocally in the direction of its axis. The pressure pad 63 has a working surface 66 interacting with the outer side of the rear wall 7 along the base 30 (FIG. 12) -. The pressure pad 63 has a drive for moving it into a working position, made in the form of a piston rod b7, which enters the pneumatic cylinder 68, fixed to the bracket 69.

Lower end hinge 72 by means of a pin 7 is pivotally connected to the upper End of the support rod 6 of the pressure pad 63.: When the cylinder 68 is triggered, causing the stem 67 to retract in the direction of the arrow 75 (Fig. 4), the articulation links 70 and 72 move the support bar b of the pressure pad; in the direction of the arrow 76. On the contrary, when The other 68 pushes the rod 67 in the direction of arrow 77 (FIGURE k}, the hinges 70 and 72 move.; the support rod b of the pressure pad 63 down in the direction of the arrow 78, whereby the working surface 66 of the pressure pad 63 passes into the groove B of the holder 55 and interacts with the outer surface of the rear wall 7 of the lid of the box 1. An adjustable screw stop 79 is mounted on the bracket B2 and protrudes to the path of movement of the bracket 73 and is connected to the hinges 70 and 72 to prevent the rod 67 from moving in the direction of arrow 77 "B Revert screw VO (Fig. and 5 which, with its head, interacts with the upper outer edge of the hinge connection 70. On the working surface 53 of the support 52 there are made longitudinal grooves 81, 82 and 83 and transverse notches 84 and 85 designed to accommodate different thicknesses of cardboard in the area of the strip 30 and for ensuring the fluidity of the activated thermoplastic material and filling all spaces between the cardboard layers within the strip 30 when these layers are clamped by the working surfaces 53 of the support 52, the surfaces 50 of the console 48 and the surface 66 of the pressure pad 63. The console 48 can move into an active position in which the flat part 49 passes through the slots 56 of the holder 55 and interacts with the outer surface of the back wall 7 of the cover along the strip 30 and retracts into the retracted: position through the slot 5b, while the working surface 50 is set to the position indicated dotted lines (Fig. 5). The pressure pad 63 is moved by the rod 67 and the hinges 70 and 72 from the extended active position, in which the flat part 49 passes through the slot 56 and working on. The surface 66 of the pressure pad 63 interacts with the outer surface of the back wall 7 of the cover along the strip 30. When the stem 67 is retracted, the i-pad 63 moves to the idle position, shown by dotted lines (Fig. 5. During operation, the box 1 moves sequentially from position 1 to position V1 (Fig. 3 in the direction of arrow 36. When box 1 moves from the wide end of groove 39 formed by edges 37 of the closing plates 38 to the narrow end of groove 39, the walls of the top cover are folded and from position, the transition shown in Fig. 9 in posited This is shown in Fig. 10. When locking flap 26 and fastening strips 22 and 25 interact with guide protrusion 57
    holder 55, the protruding part of the tong is directed into the gap between the holder 55 and the working surface 53 of the support 52. When the box reaches the activation node kS (Fig. 3), it acts on a microswitch connected to the control unit for acoustic welding. At the same time, the flat part 49 of the console A8 begins to vibrate (oscillating) (and c with a predetermined frequency, which is washed away from the retracted active working / southing, when the working surface 50 protrudes through the slot 56 and interacts with the cardboard layers of the lid i.e. in the zone of the strip 30 (fig. tl and 12). Vibrating the console kB generates a sufficient amount of heat through friction, activating the thermoplastic material of the cardboard coating along the strip 30
    After the console 48 vibrates in conjunction with the outer surface of the cardboard layers, which lasts for a predetermined period of time (.0.15 s), the console vibrates off, but the cardboard layers are clamped for a second predetermined period of time (0.25 s) to ensure initial hardening of the thermoplastic material and the start of sealing. Initial
    the hardening is facilitated by the flow of cooling fluid passing through the channels 5 and 86 of the support 52. Then the console 48 is retracted from the interaction with the cardboard layers, and the holder 55 prevents the layers from separating, although the thermoplastic material hardens only partially. Next box 1 re-. given by the conveyor 33 to the clamping and fixing unit 46 (position U1, fig. 3), the pneumatic cylinder 68 is activated, the cylinder b7 of the cylinder moves the pressure pad 63 in the direction of the arrow 73 (fig. 4). The pressure pad 66 working surface 66 interacts with the outer surface of the cardboard layers along strip 30, pressing them against the work surface 53 with a predetermined force “for a certain period of time during which the thermoplastic material finally hardens and forms a joint. The clamping and sealing cycle should continue approximately at the same time as the activation cycle. The console 48 clamps the cardboard layers for P, 40 s, of which 0.15 s it vibrates, 0.25 s compresses and holds these layers. Consequently, the cycle of clamping and fastening, in which the box 1 is clamped between the working surfaces 66 and 53, respectively, of the push-button 63 and the support 52 must last 0.40 s.
