Description

AUTOMATIC MACHINE FOR THE MANUFACTURE OF PACKAGES OF GLUED CELLULAR FILLERS

It was filed on February 6, 1961, No. 696685/25 to the Committee on Inventions and Discoveries at the Council of Ministers of the USSR

Published in the Bulletin of Inventions N And 1962,

Automatic machines for the manufacture of packages of glued honeycomb fillers by the method of stretching are known (for example, from ed. St. No. 114884 clause 21h, 29k). These machines are made in the form of a glue applicator, a trimming mechanism, a tape feed, a drying cabinet and a bag folding unit.

However, the known machines do not provide the necessary quality and performance in the process of gluing.

The proposed machine is free of these disadvantages. The essence of the invention is that the machine has a device for piercing the drainage holes in the bag.

FIG. 1 schematically shows the proposed machine; in fig. 2 schematically - klenka; in fig. 3 schematically shows a device for piercing drainage holes.

The machine consists of an upper film /, an upper clamp 2 of the foil of the lower clamp 5 of the foil, a lower button 4, a mechanism 5 for cutting and feeding the tape, a drying cabinet 6, a package folding unit 7 and a device 8 for piercing the drainage holes in the bag.

Adhesive strips are applied to the two sides of the foil 9 with the help of 1 to 4 films. To ensure a tight fit of the foil to the sheets, the clamps are 2 n 3. They are made of soft porous material such as paralon.

Kle nka 4 consists of a body and a replaceable plate. The replaceable bar has working parts defining the geometry of the adhesive strip. The depth and width of the main groove determine the thickness and width of the adhesive strip.

To obtain stable dimensions of all adhesive strips, the slit a is made within strict limits.

No. 147567-2. The housing has a hole b through which compressed air enters the cell.

The tape is trimmed with the help of disk knives of the mechanism 5, the tape is fed with drums, between which the tape is clamped. The speed of rotation of the drums is kinematically associated with the stroke of the cylinders of the package folding unit 7, which are the drive for the drums.

The device for piercing the drainage holes in the bag consists of the base 8, the puller 9, the needle holder 10, the spring Y / and the stop 12 of the stroke.

In the initial position, the needle 13 is recessed. Between the puller 9 and the base 8 there is a gap equal to the course of the puller. After the carriages 14 and 15 touch, the gap between the puller and the base is selected. In this case, the needles pierce the next fold of the foil.

The tape is folded into the bag with the help of carriages 14 and 15, which reciprocate. During the approach of the carriages a loop is formed with a free bending of the tape.

In the conclusion it is stated that in the proposed machine, the exact combination of adhesive strips and obtaining the correct geometry of the cells of the honeycomb core is carried out by simultaneously folding the tape into a bag and forming drainage holes.

Subject invention

A machine for the manufacture of bags of glued honeycomb fillers by the method of stretching, consisting of a glue applicator, a trimming mechanism, a tape feed, a drying cabinet and a folding unit: a bag, characterized in that, in order to improve the performance and quality of gluing, piercing the drainage holes in the package.
