Abstract

The invention relates to equipment for the production of containers and improves the quality of packaging boxes by making them more complex in shape and increasing the reliability of the bonding of the valves forming the box. The design of the device for forming packing boxes comprises a magazine 1, a feeding carriage with vacuum grippers 2, a molding mechanism including a punch 3 and a spring-loaded platform 4, a slider 5, a matrix 6, a carrier 7, mechanisms for applying glue, curvilinear copiers, spring-loaded conveyors 10. The production of packaging boxes is carried out by squeezing the cardboard blank through the die 6, where the corresponding flaps of the corresponding valves around the punch 3 occur, the lubrication of two end flaps with glue, and Further movement - clamping them with the help of curvilinear copiers and spring-loaded conveyors 10 against the walls of the formed box. When transferring the box by conveyors 10 to the receiving platform 16, all adhesive joints harden. 9 il. i SL / 4 00 yo 05 4 01 FIG. R

Description

The invention relates to the manufacture of containers, in particular to equipment for the formation of packaging boxes for irons.

The aim of the invention is to improve the quality of the packaging boxes.

down the punch 3 with the spring-loaded pad 4 with the workpiece 26 sandwiched between them, valves B and C, slides on the copiers 17 and 18, bend upwards by a certain angle, after which the valves D and D begin to slide along the side walls 19 and 20 of the die 6, which Fold up valves B and C to bend toward the bottom of the formed box, forming the front BB in FIG. 7; in fig. 9 - box blank.

A device for forming packing boxes comprises a blank shop 1, a feed carriage with vacuum grippers 2, a molding mechanism including a punch 3, a spring-loaded platform 4, a slider 5, a matrix 6 having a vertical and horizontal direction of FIG. 1 shows the proposed device, a general view; in fig. 2-5 - forming the box; in fig. 6 - forming mechanism, in the plan; in fig. 7 - top layer. At the moment of hemming, the breach A-A in FIG. 6; in fig. 8 - cross-section valves G and D, blank 26 with zones E, F, K, I and M, slipping along the sclees 21 and 22, also begins to bend along line a, pressing against the back wall of the punch 3, while valves G and And they pass under the copiers 17 and 18 into the gap b (Fig. 7). When approaching an imaginary line passing through the center of rotation of roller 25 and center of radius 21 and 22, valves D and D fully clamping, drove 7, mechanism 8 to go to walls of punch 3, forming the first bearing on box valves , the curved side walls of the boxes, and the valve-shaft copying machine 9, spring-loaded trans B and B are pressed by zone E to the porters 10 to press the valves and the fitting 26 to the face of the punch 3, forming the input of the formed boxes. There is a layer of the bottom of the box (Fig. 3). In the same linear guides 11, and with the punching edge of the valves J and I, the articulated pivotally connected spring-loaded board to the rollers 25 as the workpiece 26 is moved downwards is smeared with glue. Further movement of the punch 3 with the half-formed box around the radius of sclizy leads to the bending of the workpiece 26 along the line b and preloading of the zone K to the punch 3 (Fig. 4). Valves G and I with adhesive strips applied to them go under curvilinear cam drivers 9 and 23, the slides on which are folded down and pressed against the formed box (Fig. 5) and glued to form the second 5 layer of end walls. The further stroke of the punch 3 with the box formed around it occurs in the space between the two conveyors 10, where there are special pullers for removing the box from

The khanizms 8 and 24 are mounted on the side 40 of the punch 3. During the return stroke of the punch 3 walls 19 and 20 of the die 6. The strippers remove the box and it is conveyed by the conveyors 10 to the receiving area. The device works as follows.

The process of forming the box due to the formation of the box mechanisms 8

cooking 26 is as follows. 24 are not involved. Their role is reduced to

Vacuum grippers 2 stack the blank in order to apply a strip of glue intermediary 26 into the mold area of the matrix 6, with a roller 25 on the valves G and I,

that zone A of workpiece 2 lies on the spring-loaded platform 4, zones B and C) on copiers 17 and 18 of the forming matrix 6, zones D and D on the upper edges of walls 19 and 20, and zones E, F, I and K - on the slide 21 and 22.

At the initial moment of the process, the punch 3 lies on the area A of the workpiece 26,

form 4 for box blank, slider 5 and carrier 7, which is mounted with the possibility of reciprocating movement in curvilinear guides 11 by means of crank 12 from distribution shaft 11 through chain drives 14. There is an additional crank 15 for driving the feed carriage with vacuum grippers 2, as well as the receiving platform 16 for finished boxes, copiers 17 and 18 in the matrix 6 and side walls 19 and 20 with slides 21 and 22.

In addition to the curvilinear copier 9, there is a copier 23 and an additional mechanism 24 for applying glue using drive rollers 25 to the valves of the workpieces 26. Me50

at the same time, the adhesives are cured during the transfer of the box by the conveyors 10.

Claims (1)

Invention Formula A device for forming packing boxes containing a blank shop, a feed carriage with vacuum grippers, a molding mechanism, including the dimensions of the punch 3, coincide with its punch, matrix and curviline comas with the dimensions of zone A. Then, along the textupira, and curvilinear guides, from zones B , C, D, D, F, and I are called, characterized by the fact that, in order to increase valves.
