Abstract

PURPOSE:To reduce the volume of blanket or quilted bedcover having a large volume of air to perform packing thereof with ease by providing a press plate to be actuated by a drive device on a base frame, disposing a proper number of suction nozzles and a heat seal device connected to a suction device on one side of the frame, and providing a drive device for moving the suction nozzles forwardly and rearwardly. CONSTITUTION:A press plate 2 is opened and closed by air cylinders 3, 3 which are provided on both sides of a base frame and controlled by a relay control circuit. Suction nozzles 4a, 4b which are transversely moved by air cylinders 5, 5 are usually positioned at advanced locations. The nozzle 4b on the right side is such that it can be moved to right and left relative to a bracket 6 for holding said nozzle by operating a knob 7. And the nozzle 4a on the left side is fixed to a bracket for holding said nozzle. The nozzles 4a, 4b are connected to suction devices 9, 9 respectively through suction pipes 8, 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a compression packaging machine used for packaging blankets, futons, etc. with a large air volume.

[Conventional technology]

Bulky items with large air volumes, such as blankets and futons, are packaged at retailers and dry cleaning shops by wrapping them in wrapping paper and tying them with string, or placing them in plastic bags and heat-sealing the openings.

The former method has a slightly smaller bulk (and is easier to handle), but it is troublesome as you have to press down when tying the string.Also, the latter method allows the air to be sealed as it is. It was bulky and difficult to handle.

[Problems to be Solved by the Invention] The present invention aims to provide a packaging machine that can easily package blankets, futons, etc. that have a large air volume by reducing their bulk.

[Means to solve the problem]

This invention was made in order to solve the above problems, and a pressure plate operated by a drive device is provided on the base, and an appropriate number of intake nozzles connected to an intake device and a heat seal are installed on one side of the base. This compression packaging machine is characterized in that it is provided with a drive device that moves the suction nozzle back and forth.

[Effect]

A heat-sealable packaging bag containing an item to be packaged is placed on a base, a pressure plate is operated by a drive device to pressurize the packaging bag, and then air is pumped into the packaging bag through an air intake nozzle connected to an air intake device. After exhausting the air, the suction nozzle is moved to pull it out from the opening of the packaging bag, and then the heat sealing device is activated to seal the opening of the packaging.

〔Example〕

FIG. 1 shows a perspective view of an embodiment of the present invention, in which 1 is a base, and 2 is a pressure plate whose rear portion is pivotally connected to the base 1. In FIG.

This pressure plate 2 is opened and closed by air cylinders 3.3 provided on both sides, which are controlled by a relay control circuit.

As shown in FIG. 2, 4a and 4b are air cylinders 5.
5, the intake nozzle is moved laterally, normally in an advanced position as shown in FIG.

The right intake nozzle 4b is configured to be movable left and right by operating a knob 7 with respect to a bracket 6 that holds it.

Note that the right intake nozzle 4a is fixed to a bracket that holds it.

These intake nozzles 4a, 4b are connected to intake devices 9, 9, respectively, via intake pipes 8.8.

Next, referring to the relay control circuit shown in FIG. 3, its operation will be explained.

First, a packaging bag 12 capable of heat-sealing an object to be packaged such as a blanket or futon is placed on a base l, and the suction nozzle 4a is placed in a position where both sides of the opening of the packaging bag I2 are advanced.

4b, and move the right intake nozzle 4b to the right by operating the knob 7, and set it so that the intake nozzle does not come off the opening of the packaging bag 12.

Next, step on the foot switch 11 connected to the cord 10. When the foot switch 11 is turned on, the pressure plate timer TI (set time is 55 seconds in the example) starts operating, and at the same time, the relay R1 operates and the self The holding contact rl-1 is turned on and the timer circuit is self-maintained.

On the other hand, since the contact rl-1 of the relay R1 is turned on, the left and right air cylinders 3.3 operate and the pressure plate 2 descends, pressurizing the packaging bag 12. At the same time, the protrusion 2a provided on the pressure plate 2 turns on the intake switch 13.

When the intake switch 13 is turned on, the intake device 9.9 operates to exhaust the air inside the packaging bag 12 through the intake nozzles 4a and 4b. The intake time is set using the intake device timer T2.
by. (The setting time is 25 seconds in the example.) When the thickness of the packaging bag 12 decreases and the pressure plate 2 goes down further, the nozzle evacuation switches 14 and 15 on the left and right move to the protrusion 1.
4a and 15a (one not shown), and the green lamp 16 lights up.

When the green lamp 16 lights up and the intake devices 9, 9 stop after the time set by the timer Tt has elapsed (the operation sound stops), press the red push button switch 17.

When the red pushbutton switch 17 is turned on, the nozzle retracting air cylinder 5.5 and the timer T (set time is 35 seconds in the embodiment) are operated to retract (backward) the intake nozzles 4a and 4b.

When the intake nozzles 4a and 4b are retracted, the bracket pushes the heat sealing switch 18, and the heat sealing device 19 provided on the pressure plate 2 is operated to seal the opening of the packaging bag 12.

When the time set by the timer T3 has passed, the timer contact t3 is turned off, and the intake nozzles 4a and 4b return to their initial positions.

Note that if the pressure plate 2 remains down even after the time set by the timer T3 has elapsed, the intake nozzle remains on standby because the relay contact r2-1 remains on. Collision between the intake nozzles 4a, 4b and the pressure plate 2 can be avoided.

In principle, the timer setting time is set as TI<T2+73.

[Effects of the Invention] By using the apparatus of the present invention, there is an effect that blankets, futons, and the like having a large air volume can be easily packaged with a reduced bulk.
