SU117235A1 - A device for forming and gluing the bottoms into rectangular cardboard cases - Google Patents

Description

Devices for forming and gluing the bottoms into rectangular cardboard cases were not known until recently. It is known only to use in devices for the manufacture of boxes of magazines for blanks in the form of a rectangular tray, inside of which a piston is located, which is under the influence of the load and mixes the blanks.

Therefore, the device described is new. It allowed to increase labor productivity in the operation of gluing the bottoms of 5 cases.

The described device is made in the form of periodically moving ush; its plate conveyor carries rectangular nests for cardboard cases, fixedly mounted above the conveyor of the drying plate for drying products and sequentially located on the side of the conveyor of the store for blanks of bottoms, devices for ejecting blanks from the store. forming toes consisting of a die and a punch, and devices for spreading the bottoms with glue.

A fixed rectangular tray, inside which a movable piston is located under the influence of a load suspended from a cable, is slid into a roller, is used as a store for workpieces of bottoms. The device for pushing out the blanks from the magazine is made in the form of a movable gate, kinematically connected with the plate conveyor by means of a cam mechanism i of a system of levers.

To hold the bottom on the punch during glueing, the punch has longitudinal and radial channels connected to the vacuum system.

FIG. 1 shows schematically a general view of the device; n; FIG. 2 is a device for ejecting blanks from a magazine;

from above; in fig. 3, 4, 5 and b - the punch operation scheme at various moments of formation and gluing of the bottom into the case.

The device includes a plate conveyor carrying rectangular slots 2 for cardboard covers and receiving a periodic motion from the drive wheel 3, periodically rotated, in turn, by the Maltese cross 4; the latter is kinematically connected by means of shafts 5 and 5 and conical shafts with a drive shaft 7.

A drying plate 8 for the substance of the seam of the case and the ladder inserted into it is fixedly mounted above the conveyor 1. On the side of the conveyor there is a store for blanks of bottoms and a device for ejecting blanks from the store. The magazine is made in the form of a fixed rectangular tray 9 in which 10 bottoms are laid on the edge of the workpiece. Inside the tray is a movable piston 11, pressing the workpiece against the wall 12 of the tray with the help of podvsschenpy to the cable 13, thrown over the roller 14, the load 15.

The device for pushing the blanks out of the magazine is made in the form of a gate 16 reciprocating along the conveyor by means of a system of levers and a cam / 7 mounted on a shaft 18, kinematically connected to the shaft 6 by means of an intermediate shaft 19 and bevel gears.

Following the magazine and the tool for pushing out the blanks, there is a stamp for forming a bottom consisting of a matrix 20 and a punch 21 receiving a reciprocating motion perpendicular to the conveyor at rioMonui cam 22, which is rotated by the shaft 19 by means of gear transmission. The punch 21 has longitudinal and radial channels 23 associated with a vacuum system.

To put glue on the bottom edge of the bottom, use the lever 24, dipping the adhesive bath 25 and swinging out of the cam 26 through a system of levers, and to apply the glue on the upper edge of the donkey, an eccentric 27 removing the glue from the disk 28 passing through the KoTee bath. 29. For drying the bottom of the seam of the case with the bottom, the device is equipped with a drying rod 30.

The operation of the device is performed in the following sequence.

The blank 10 of the bottom is pushed by the gate 16 from the tray 9 through the gap between the tray and the wall 12 and is fed to the punch 21, takes up space between it and the die 20. Then, the punch 21 starts to move, pushing the blank through the matrix 20 With this, the edges of the blank are bent and form the bottom . At this moment, the vacuum system is connected to the die. Due to the vacuum in the channels 23, the bottom sticks to the end of the punch. With its further movement, the eccentric 27 and the lever 24 put a layer of glue on the curved edges of the dresser, after which the bottom is inserted into the cardboard box served by the same poopson. The vacuum system is disconnected from the punch and the latter moves back.

The drying plate exudes the top seam of gluing, and the drying rod 30 - the bottom shchu. Conveyor 1 removes the finished carton and feeds the next case to the die with a die, after which the cycle described above is repeated.
