Abstract

The present invention relates to a cardboard vane folding and sealing device comprising a transporter (10), a first folding mechanism (2, 3), a second folding mechanism (1, 4), a third folding mechanism (6) and a sealing mechanism (9). It is about. The cardboard is sent onto the conveyer and is moved forward by the conveyer past the first folding mechanisms 2, 3 towards the sealing mechanism. When the cardboard hits the limit switch (LS2) 8 for the front wing air cylinder mechanism 1, the air cylinder mechanism 1 for the front wing is driven to fold the front wing, and then the cardboard is the rear wing lift mechanism 4 To the limit switch (LS1) (7). When the cardboard touches the limit switch LS1, a rear wing folding command signal is sent to the rear wing folding air cylinder 5. This unique mechanism is specific to the cardboard used. The cardboard is then moved to the sealing mechanism and sealed without interruption by two pairs of upper and lower bases working alternately and two pairs of glue tapes disposed on the tape support frame.

Description

Cardboard wing folding and sealing device {CARTON FLAP FOLDING AND SEALING MACHINE}

The present invention relates to a cardboard wing folding and sealing mechanism comprising a folding mechanism for carrying out the folding process of folding the front wing, the rear wing and two lateral wings of the cardboard, in particular continuously, and a sealing mechanism to seal the cardboard blade without interruption. will be.

Cardboard is widely used to pack many kinds of goods, and cardboard wing folding and sealing devices are also commonly used. Such conventional cardboard wing folding and sealing device is the 'automatic carton cap-folding and sealing device' described in the Republic of Korea Utility Model Publication No. 20-0252728, the contents described in the disclosure Included by reference. In the apparatus, a folding mechanism for folding the blades of the cardboard and a sealing mechanism for sealing the folded wings with a tape are connected, so that the folding process and the sealing process can be automatically performed.

However, there has been a problem in the apparatus of the utility model that when the tape is used up in the sealing apparatus and used up, the apparatus must be stopped to replace the tape cartridge.

It is therefore an object of the present invention, in particular, to provide a cardboard wing folding and sealing device of the type which continuously performs the folding and sealing operation continuously without interruption even when the tape runs out.

It is also an object of the present invention to provide a cardboard vane and a sealing device of the type which automatically adjusts the position of the folding device by sensing the size of the cardboard to which the vane is folded.

According to one aspect of the invention, in the device of the invention, three folding mechanisms are arranged in order to fold the front wings, the rear wings and the two lateral wings of the cardboard in sequence, and the folding cardboard is then folded It is supposed to be sent from the mechanism to the sealing mechanism.

As shown in FIG. 1, a preferred embodiment of the cardboard vane folding and sealing device of the present invention comprises a first folding mechanism 2, 3, a second folding mechanism 1, and a rear wing raising mechanism ( 4), rear wing folding mechanism 5 and third folding mechanism 6.

Two front posts connected by an upper horizontal beam and two rear posts connected by another upper horizontal beam are disposed opposite to the front and rear of the transporter, where the first folding units 2 and 3 and the first 2 Folding unit 1 is fixed.

In the operation of the cardboard vane folding and sealing device of the present invention, when the cardboard to be folded and sealed is placed in the device, the reduction motor rotates the roller to move the cardboard forward, the motor is operated to move the belt, and the belt is moved on both sides The cardboard is clamped to correct its position.

On the other hand, during the wing folding operation of the cardboard, the movement of the other cardboard on the conveyor is prevented, for example, by the operation of a suitable air cylinder. Here, when the previous cardboard has completed the wing folding process and is moved to the sealing mechanism, the air cylinder causes the cardboard to move the cardboard to the carrier, so that the subsequent cardboard is advanced and moved into position on the conveyor. Next, the width of the cardboard is measured by the length measuring device, and the measured value is sent to each folding unit.

When the cardboard is moved on the conveyor, the cardboard is clamped by the drive belt, and then the position data is sent to all folding units 2, 3, 1, 4, 5, 6.

Next, the heights of these units are adjusted so that the swing plates of the first folding units 2, 3 are adjusted to a height suitable for raising the front wings which may be struck down from the bottom up. The air cylinder mechanism 1 for the front wing is then actuated to fold the front wing and generate a signal informing that the cardboard is passing, and the rear wing raising mechanism 4 swings the rear wing which may be struck down. Upon receiving a command to raise the lift, the cardboard continues to move so that the front wing contacts the other cardboard.

The rear wing folding mechanism 5 of the swing pressing means then presses the rear wing down into the cardboard. As the cardboard continues to move past the conveyer, the third folding mechanism 6 folds the wings on both sides, so that the wings on both sides of the carton are fully folded, whereby the two wings on both sides are folded together. It will have a final shape in contact.

The cardboard is then moved to a sealing mechanism, which has two pairs of upper and lower bases that operate alternately so that the sealing process can not be stopped even if either tape is exhausted. The pair of upper and lower bases can be immediately replaced with another pair of upper and lower bases even if either tape is exhausted, so there is no need to interrupt the sealing device to replace the tape.

While preferred embodiments of the invention have been described, various modifications may be made to the invention and the claims are intended to cover all such modifications without departing from the spirit and scope of the invention.

According to the configuration of the present invention, the folding and sealing device which automatically performs folding and sealing of the cardboard blades can perform the cardboard blade folding and sealing operation continuously without interruption.
