Description

DETAILED DESCRIPTION OF THE INVENTION The present invention also relates to a crimping device in a tablet packaging machine.
It's a good thing.

Generally, a PVC sheet is wrapped around the outer circumferential surface of a die roll, and the sheet is heated and sent in the rotating direction, and the tablets placed on the top surface of the PVC sheet are wrapped with aluminum foil coming from the other direction and crimped with a seal roll. The notches often damage aluminum foil.

This is because the PVC sheet swells as it is pressed against the tablet during crimping, but the force of the PVC sheet trying to return to its original state pushes up the aluminum foil, and when the curved part of the tablet is crimped with a seal roll, it is pushed strongly and that part breaks. be.

In addition, since tablet-pushing holes are arranged at equal intervals on the outer circumferential surface of the die roll, when a PVC sheet is crimped with a seal roll, the portions with the holes and the portions without holes are crimped. changes, often resulting in pinholes.

The present invention aims to solve the problems in the conventional tablet packaging machine, and its configuration will be explained as follows.

This invention is a tablet packaging machine that directly seals tablets between a PVC sheet and aluminum foil, in which a rubber roll is disposed in front of the sheet TV roll, and the rubber roll seals the tablets placed on the top surface of the PVC sheet. The rubber roll is pressed from the top of the aluminum foil that is rotating from the other direction, and when the rubber roll is located above the tablet-pushing hole of the die roll, the seal roll is located between the holes, and the rubber roll is pressed into the hole. and the hole, the seal roll is disposed so as to be located above the hole.

Embodiments of the present invention will be described below with reference to the drawings.

In the drawing, the PVC wound around the outer circumference of the die roll 1
When the sheet 2 is heated and sent to the top by the rotation of the die roll 1, the tablets 4 sent by the pocket roll 3 are placed on the top surface of the PVC sheet 2 and moved in the rotation direction of the die roll 1.

In this case, the tablets 4 are placed on the top surface of the PVC sheet 2 located above the tablet-pushing holes 5 arranged at equal intervals on the outer peripheral surface of the die roll 1, as shown in FIG. .

An aluminum foil 6 for sandwiching and sealing the tablet 4 from above the PVC sheet 2 is pulled and pressed by a tension roll 7, a rubber roll 8, and a seal roll 9, and is then sent sealed.

The rubber roll 8 presses the tablet 4 placed on the top surface of the PVC sheet 2 from the top of the aluminum foil 6, as shown in FIG. and the aluminum foil 6.

The rubber roll 8 and the seal roll 9 are arranged so that when one is located above the tablet-pushing hole 5 of the die roll 1, the other is located between the holes 5.

The tension roll 7, rubber roll 8, and seal roll 9 are rotatably attached to a roller bracket 10, and are activated by tilting a lever 11 as shown in FIG.

That is, when the lever 11 is pushed down, the crank pin 14 of the crank 13 attached to the tip of the lever shaft 12 is moved to the tension rod 1.
5 to pull the pressure lever 16 and rotate the square metal shaft 17 counterclockwise.

A square metal 18 is attached to the tip of the square metal shaft 17, and is attached to the roller bracket 10 via a plate spring 19 and a seal roll pressure bolt 20.

Therefore, by tilting the lever 11, the roller bracket 10 is actuated, which causes the tension roll 7, rubber roll 8 and seal roll 9 to operate simultaneously, with the tension roll I pulling the aluminum foil 6 and the rubber roll 8 As shown in FIG. 3, the tablet 4 is sandwiched between the PVC sheet 2 and the aluminum foil 6 and pushed into the tablet pushing hole 5 of the die roll 1. This will seal the foil 6.

The seal roll pressure bolt 20 allows the roller bracket 10 to be adjusted at a constant angle with respect to the outer peripheral surface of the die roll 1.

Next, in order to adjust the strength of the pressure bond, the strength of the spring 21 that urges the pressure lever 16 may be adjusted by rotating a nut 22 screwed onto the tip of the tension rod 15.

As explained above, according to the crimping device in the tablet packaging machine of the present invention, the rubber roll disposed in front of the seal roll holds the tablet placed on the top surface of the PVC sheet with the aluminum foil rotating from the other direction. The rubber roll and the seal roll are arranged such that when one of the rubber rolls and the seal roll is located above the tablet-pushing hole of the die roll, the other is located between the holes. This allows the sealing roll to seal the aluminum foil before it tries to push up due to the restoring force of the PVC sheet pushed inside the tablet-pushing hole of the die roll, and balances the pressure applied to the PVC sheet. There will be no damage to the packaged product.

Note that the tablet may be of any shape or size, and may also be capsule-like.

[Brief explanation of drawings]

The drawings show one embodiment of the crimping device in the tablet packaging machine of the present invention, and FIG. 1 is a plan view thereof, FIG. 2 is a front view thereof, and FIG. 3 is an enlarged view of the main part of FIG. 2. be. In the drawings, 1 is a die roll, 2 is a PVC sheet, 3 is a pocket roll, 4 is a tablet, 5 is a hole for pushing a tablet, 6 is an aluminum foil, 8 is a rubber roll, and 9 is a seal roll.

Claims (1)

[Claims] 1.
