SU119793A1 - Device for applying glue to cardboard blanks - Google Patents

Description

The device is intended for applying glue to the cardboard blanks in the cardboard production.

The known devices of this purpose usually include a roller, applying glue on the bottom blank, a blank magazine and a device for pulling the bottom blank out of the magazine, and this fixture is made differently in different devices.

In the described device, it has an original design, which allows to increase labor productivity, and is made in the form of a roller with a needle and a pin located under the magazine, and two rollers located next to the magazine and serving to further advance the advanced workpiece.

A roller with a needle and a pin is provided with a mechanism for automatically turning it on when it is removed from the previous device, lubricated with a workpiece glue, which includes a spring-loaded lever that interacts with one roller shoulder and roller, which interacts with a support roller, which is designed to skip the workpiece .

The drawing shows a schematic view of the device.

On the skeleton, shop 1 is mounted with a stack of cardboard blanks. A roller 2 is installed under the magazine with a needle 3 and a pin 4 for pulling the bottom blank out of the magazine. Next to it is a pair of rollers 5, of which the upper rubberized. Next, the controversial roller 6, the guide roller 7 and the glue roller 8, interacting with the drum 9 partially immersed in the adhesive bath 10, are mounted.

Under the rollers 5 there is mounted a pivoting arm about the axis //, provided with a spring 13 on one shoulder and a roller 14 on the other, resting against the support roller 6.

Roller 2 rotates with needle 3 the lower billet from magazine 1 and feeds to a pair of rollers 5, which further promote it

between the support roller 6 and the roller 14 to the glue roller 8. The latter, taking the glue from the drum 9, applies it to the workpiece.

At the same time, the workpiece, advancing between the support roller 6 and the roller 14, deflects the lever 12, which engages the pin 4 on the left shoulder and stops the roller 2. After the rear end of the workpiece leaves the clamp between the rollers 5, it is pushed manually between rollers 7 and S; at the same time, the rear end of the preform is lubricated with glue.

Upon leaving the workpiece from under the roller 6, the lever 12 is turned counter-clockwise by the action of the spring 13. The protrusion on the left arm of the lever disengages from the pin 4 and the roller / which is not restrained by the lever 12, rotates, gripping the next workpiece.

Subject invention

Claims (2)

1. A device for applying glue to cardboard blanks, including a roller, depositing glue on the lower blank, a blank magazine and a device for pulling out the blank, i & U, which, in order to increase productivity, for example, in carton making, the device for pulling out of the store the billet is made in the form of a roller located under the magazine with a needle and a pin, two rollers to further advance the workpiece and a mechanism to automatically turn on the roller with a needle and pin upon release of the device with adhesive previously lubricated preform. 2. The device according to claim 1, characterized in that the mechanism for automatically switching on the roller with the needle and the pin is designed as a spring-loaded lever cooperating with the roller pin with a roller interacting with a support roller for passing the workpiece on the second shoulder.
