typical technology for manufacturing paper/cardboard cups in the shape of a truncated cone are presented.
In general, the process is divided into 8­10 separate operations, some of which occur in parallel, some in sequence. These operations are as follows: cutting a round bottom blank from a roll of paper tape; forming a cup­shaped bottom; manufacturing cup body blanks; moving body blanks one by one from the self­loading magazine; forming the body by gluing its side edges; attaching the bottom to the body (heating hot melt adhesive in the lower part of the body, attaching the cup­shaped bottom to the body, wrapping the lower part of the body inside the cup, rolling the body strip to the wall of the cup­shaped bottom with special grooved rollers); rolling the upper edge of the cup, creating a protective rim at the top of the conical container; moving the finished product for packaging into group packaging.
A diagram of a typical machine for the production of paper and cardboard cups in a rotary machine has been presented and its description has been given. The main operations performed in the machine are described, the limits of the capabilities of the machines are determined, and parts that significantly affect the productivity, energy efficiency of the equipment and product quality are identified. of paper food containers.
It is determined that there are quite a few product parameters (height, diameter of the upper rim and volume of the container), but there is a wide range of ratios of the sizes of conical cardboard containers and the volumes that the mentioned containers can contain. A classification of such products is made according to the ratio of sizes and volume (capacity). Іt is proposed to divide containers into three large groups, each of which has a different purpose, size ratio, and, accordingly, equipment.
A classification of automated equipment for the manufacture of conical paper cups is presented separately. Machines are divided by the location of the shafts and drives of the main tools (horizontal and vertical), the discontinuity of movement (with periodic stops and continuous).
