Description

The invention relates to the packaging of products in containers and can be used in the food, light and chemical-pharmaceutical industry.

The purpose of the invention is to increase reliability by preventing jamming of blanks during feeding, as well as expanding technological capabilities by ensuring the formation of boxes of various sizes.

FIG. 1 shows a device for single-piece feeding from the stack of cardboard flat billets of boxes and their formation, general view; in fig. 2 — fastening unit for supporting magazine guides; in fig. 3 - grip fastening assembly on the feeding conveyor.

A device for feeding one piece from a stack of cardboard flat billet boxes and forming them comprises a magazine 1 consisting of a base 2 and supporting guides 3 for placing the blanks, a sequentially installed feed conveyor 4 with a grab 5 and a conveyor 6 for individually feeding shaped boxes. The gripper 5 is spring-loaded by means of springs 7 relative to the sleeves 8 and rods 9, the lower ends of which are bent outward relative to the feed conveyor 4, and is placed between these rods. The feeding conveyor 4 and the conveyor 6 for the single-piece feeding of the formed boxes are installed along one axis, while the conveyor 6 is made with an inclined entrance section. At the level of the base 2 of the magazine along the entire length of the feeding conveyor 4 and the conveyor 6 for single-piece feeding of the formed boxes, supporting planes 10 are installed with a gap for the pressure plate AND mounted on the supporting body of the conveyor 6. Pressing guides 12 are mounted along the feeding conveyor 4 and conveyor 6 14 to close the valves. Under the feed conveyor 4 mounted the copier 15, while the grip 5 is installed with the ability to interact with this copier.

In order to ensure the formation of drawers of various sizes, the supporting guides 3 of the magazine 1 can be made with the possibility of changing the distance between them, and the inclined entrance section of the conveyor 6 for the single-feed of the formed beads with the possibility of changing the angle of inclination. To do this, on the basis of 2 magazines, through-shaped figured cuts are formed, into which the lower ends of the supporting rails 3, fixed by nuts 16, are inserted. To change the angle of inclination of the inclined entrance

In the first part of the conveyor 6, plates 17 are provided with a series of communicating horizontal slits, in which the axes of the support roller 18 of the conveyor 6 are fixed for feeding the formed boxes into a single piece. The clamping guide 14 can be made height-adjustable.

A device for single-piece feeding from the stack of cardboard flat billets of boxes and their formation works as follows.

The feeding conveyor 4 communicates in a discontinuous motion with equal time intervals proportional to the width of the flat-laid box. Before the magazine 1, the rods 9 are bent to the outside with respect to the feeding conveyor 4 by the ends of the copier 15. At the same time, the grip 5, rigidly fixed between the rods 9, is lowered to the level of the bottom in the stack of the flat box at the bottom edge of the upper plane. A pressure plate 11 enters between them in front of the drawer. The movements of the feed conveyor 4 and the conveyor 6 are synchronized and carried out at equal speeds. But when moving along an inclined section, the horizontal component of the speed of the pressure plate 11 is less than the corresponding value of the capture speed 5, therefore the distance between them begins to decrease and when the clamps exit to the horizontal section of the conveyors, it becomes equal to the width of the bottom box.

The gripper 5, pressing on the edge of a flat-folded box, resting against another edge on the pressure plate II, moves closer to the edge box in parallel to the full opening (forming a rectangle in cross section) as it approaches the latter. Upon further movement of the formed box, fixed in the horizontal plane by the pressure guides 14, its external and internal valves are driven by the pressure guides 12 and 13 to the desired position for subsequent filling on one of the sides.

When switching to working with boxes of another size, the guides 3 are mounted on the base 2 in accordance with the new dimensions. By changing the position of the support roller 18 in the slots of the plate 17, depending on the size of the box being formed, the angle of inclination of the entrance section of the conveyor 6 is also regulated, and consequently, the speed of movement of the gripper 5 along it.
