SEALING AND CUTTING UNIT FOR A FORM FILL SEAL MACHINE

摘要

An apparatus for packing articles, wherein the packing is formed by at least one web material, wherein typically a plurality of individual juxtaposed runs of web material and a number of more or less packed articles are conveyed on the runs, wherein the apparatus includes first mechanism which, during packing of articles, joins the web material continuously in its longitudinal direction, as well as other mechanisms for producing individual joints and for separation of the articles in a transverse direction of the web material, wherein the mentioned other mechanisms are arranged on moving means adapted to move in the same direction and at the same speed as the web material and the articles being packed, called the X-axis, and in a direction towards the web material and the articles arranged thereon, called the Y-axis.

1. An apparatus for packing confectionery articles, wherein the packing is formed by at least one web material, and packed articles are conveyed on the runs, wherein the apparatus includes first means which during packing of articles join the web material continuously in its longitudinal direction as well as other means for producing individual joints and for separation of packed articles in a transverse direction of the web material, wherein said other means are arranged on moving means adapted to move in the same direction and at the same speed as the web material and the articles being packed, called the direction of the X-axis, and in a direction toward the web material and the articles arranged thereon, called the direction of the Y-axis, wherein the apparatus includes at least one individual joining unit for each run of web material and at least one individual cutting unit for each run, wherein the joining unit and the cutting unit are built together as a combined unit, and wherein the combined unit is connected with control means for individual control of the moving pattern and speed of the combined unit, wherein the apparatus is arranged with the first means as well as the second means in a coinciding and substantially horizontal processing plane;
where the processing plane extends in a direction corresponding to the direction of the X-axis where the packing in this plane is joined in a longitudinal direction as well as the transverse direction; where a joining unit and a cutting unit in the combined unit each include means for moving in the Y-axis direction at least partially independently of each other; where the joining means includes a lower jaw member and an upper jaw member, where the lower as well as the upper jaw members include moving means for moving respective parts in the direction of the Y-axis; wherein the apparatus further includes sensing means which are connected to control means for determining an expression of the distance between a lower jaw member and an upper jaw member in a set of joining means when the latter are activated, and the speed of the joining unit relative to the conveying speed of the articles is adjustable in the direction of the X-axis such that the joining is performed close to the product.
