Description

[Detailed Description of the Invention] The present invention relates to a gluing device that applies glue to the gluing portion of wrapping paper when wrapping a product with wrapping paper.

Conventionally, the pasting of wrapping paper in packaging machines has been carried out using a gluing device built into the device. The lower part of the body is immersed in the glue solution, and an appropriate number of gluing pieces are protruded around the body in a water wheel shape, and the tips of the gluing pieces are brought into contact with the surface of the wrapping paper to perform gluing.

Therefore, the entire surface of the size liquid stored in the size bottle is directly exposed to the outside air, and there is the inconvenience that the surface of the size liquid may harden while the device is stopped or stopped during lunch breaks or at night. In addition, the glue adhered to the periphery of the opening of the glue pot, making it troublesome to clean the glue pot.

However, in view of the conventional situation of slanting, the present invention solves the above-mentioned inconvenience by providing a gluing device in which the surface of the glue does not solidify while the device is stopped during lunch breaks or at night, and the gluing pot is easy to clean. The purpose is to eliminate the problem.

Hereinafter, one embodiment of the gluing device of the present invention will be explained with reference to the drawings. Fig. 1 is a front view of the gluing device showing the gluing pot cut away;
It consists of a glue pot 1, a glue piece 2, a swinging rod 3 for moving the glue piece 2 up and down, a rotating shaft 4, etc., and the glue pot 1 has a substantially box-shaped glue pot body 5.
A lid body 6 is removably fitted onto the upper part of the flexible plate 7, which will be described later.
At the same time, a glued piece 2 is attached to the lid body 6.
An elongated hole 9 is bored into which the elongated hole 9 enters and exits in a loose-fitting manner, and a receiving rod 10 is provided above the elongated hole 9.

The flexible plate 7 is made of a flexible material such as rubber, and its peripheral edge is attached to the window 8 in an airtight manner with a holding frame 11, 12.

The rotating shaft 4 is used to raise and lower the glued piece 2 by its rotating operation, and is rotatably inserted into bearings 13 provided integrally with the glue pot body 5 on both sides of the window 8, and is held at one end. A mating protrusion 14 is carved, and a torsion coil spring 1 is inserted between the glue pot body 5 and the other end.
5 is attached, and the flexible plate 7 and the clamping piece 16 are fixed to the central part 4' with bolts 17, and the swinging rod 3 is attached to the clamping piece 16.
to fix.

The gluing piece 2 is a flat plate with an approximately wedge-shaped upper part 2' and a window 18 cut out in the center.
7 so as to be slidable up and down, and the hanging window 18
The tip of the swinging rod 3 is inserted into the holder.

Further, an arm rod 20 is rotatably attached to the middle of a support rod 19 set up near the glue pot body 5, and an engaging piece 21 provided integrally with the arm rod 20 is attached to the rotation shaft 4. A tension spring 21 is engaged with the engaging protrusion 14 in a detachable manner, and a tension spring 21 is hung across the swinging end of the arm rod 20 and the upper part of the support rod 19, and an interlocking mechanism for placing the packages at an appropriate position on the swinging end is provided. The working end of the wire 22, which is driven by a wire (not shown), is engaged with a latch piece 23.

Therefore, when a predetermined amount of sizing liquid 24 is added to the sizing pot 1 and the device is started, if the wrapping paper 25 is not in the sizing section 26 which is composed of the upper surface of the lid 6 and the receiving rod 10, , the wire 22 is pulled by the interlocking mechanism of the packaging device, and the arm rod 20 rotates counterclockwise, pulling the tension spring 21, as shown in the first step, and stops at its lower limit position.

When the arm rod 20 rotates counterclockwise, the rotating shaft 4 that engages with it rotates counterclockwise, and the swinging rod 3 fixed to the rotating shaft 4 swings downward, causing the glued piece 2 to Position it at the lower limit.

When the upper end surface 2'' of the glued piece 2 sinks below the glue liquid level 24' and reaches the lower limit position, the wrapping paper 25 is inserted into the glued part 26, and the wire 22 is When the arm rod 20 is loosened, it rotates clockwise due to the elastic force of the tension spring 21, and the swing rod 3 raises the glued piece 2, and the wrapping paper 25 is attached to the receiving rod 10 with its upper end surface 2''. Glue while pressing.

When the gluing piece 2 finishes gluing the wrapping paper 25 with its upper end surface 2'', the wire 22 is pulled to lower the gluing piece 2 and the wrapping paper 25 is pulled out to complete the gluing operation.

In this invention, a flexible plate is attached to the window that opens on the side of the glue pot as shown in the diagonal above, and the glued piece is moved up and down from this flexible plate via a swinging rod to open a hole in the upper lid. Since it is made to protrude and retract from the elongated hole, when the glue-applying piece is immersed in the glue pot, both the glue-applying piece and the swing rod that drives it are below the glue surface and do not come into contact with air. Therefore, it is possible to eliminate the factors that cause the glue that adheres to the glue strips, swinging rods, etc. to dry and grow.Moreover, since the inside of the glue pot and the outside are only connected through a long hole in the lid, outside air cannot be drawn into the glue pot. It does not easily flow, and the surface of the size liquid will not dry and harden even if left for a long time.

Further, during the gluing operation, the gluing piece and the swinging rod do not come into contact with the outer surface of the gluing pot and stain the iron surface with glue, so there is very little need for cleaning, which is practical.

Therefore, the intended purpose can be achieved.
