Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to raw meat, ham and other foods, and electric / electrical devices such as ICs.
TECHNICAL FIELD The present invention relates to a vacuum or a gas filling packaging device capable of simply vacuum-packing electronic parts, automobile parts, etc., as needed, or gas filling after vacuuming.

[Prior Art] Conventionally used vacuum or gas filling packaging devices of this type are shown in FIGS.
-1887 is a packaging device for vacuum or gas filling described in Japanese Patent Laid-Open No. 1887, which comprises a pair of holding rods 16 and 16 and a pair of heat-sealing rods 17 which sandwich the tip of a pair of nozzles 15 and 15 provided at the center of the device body from above and below. , 17 are provided, and in use, a bag containing the required foods, etc. is first fitted with the opening of the bag at the tip of the nozzles 15, 15, and then the bag is held by a pair of clamping rods 16, 16. After holding the mouth edge together with the nozzles 15 and 15 from above and below under pressure and operating a vacuum pump (not shown) connected to the base ends of the nozzles 15 and 15 to suck air in the bag, The heat-sealing rods (17, 17) are pressed to heat-bond the edges of the bag body, and the pair of heat-sealing rods (17, 17) and the pair of holding bars (16, 16) are opened to take out a desired bag body.

[Problems to be Solved by the Invention] In the prior art, the airtightness of the packaging bag and the complete sealing have been solved to some extent in that the nozzle is movable. However, when the nozzle that is retracted to the rear at the time of heat sealing is returned to the front and prepared for the next packaging work, the nozzle cannot be smoothly returned to the original position because the nozzle is configured to be pulled forward by the spring 64. There was a point.

That is, when the sliding member 19 is caught in the middle of the sliding member due to the momentary contraction of the spring, or when the contracting force of the spring becomes weak, the original position cannot be smoothly and accurately restored.

Further, since the nozzle is fitted in the sliding body 19 composed of a rectangular tubular body so as to be movable back and forth, if dust or oil lumps accumulate in this sliding body, the sliding operation of the nozzle becomes hard. , There was a problem that could not be pulled by the spring. In particular, when the apparatus was in operation, mist-like dust was constantly floating around the nozzle, and it was easy for dust to collect in the sliding body. Moreover, the lubricating oil is contained in the sliding body to assist the sliding of the nozzle, and this lubricating oil is easy to fix according to the frequent back-and-forth movement of the nozzle.

Therefore, it has been desired to develop a vacuum or gas filling packaging device that can smoothly and accurately move the nozzle back and forth even when it is used for a long period of time.

In the prior art, the two clutches 39, 39 are used to allow the two sliding members 19, 19 which are mounted with nozzles via the gears 42, 42, the driving members 44, 44 and the gear 45 to be movable left and right. There is. In this way, since the two slides 19 and 19 are independently driven by separate drive systems, their left and right movements often do not completely match, resulting in unbalanced left and right nozzle openings. Since the nozzle does not open at a predetermined position in the center of the base, the set bag body often moves and comes off the nozzle, and there is a problem that a vacuum cannot be created.

Furthermore, in the prior art, a sliding body 19 made of a rectangular tubular body,
19 is slidably mounted on four support rods 18 at its four corners so that it can be moved left and right. When it is mounted on the support rods 18, mounting holes are provided at four corners of the sliding body. A total of 16 holes must be drilled, and when drilling these 16 fitting holes, it is necessary to completely match the drilling positions of all the fitting holes, which is extremely difficult to process. It was If the 16 mounting holes are slightly inconsistent with each other, there is a problem in that the sliding body does not move right and left smoothly, and the nozzle cannot move smoothly left and right.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems existing in the above-mentioned conventional technology, and makes a pair of two nozzles smoothly and accurately movable back and forth and left and right, and the two nozzles are packaged. Accurately positioned on both sides of the bag to freely conform to the large and small shapes of various packaging bags, aiming at smooth and reliable air suction or gas filling while improving work efficiency .

Further, the present invention holds the nozzle and the rim of the bag body airtightly with a holding rod at the time of sucking air or filling gas, and at the time of heat sealing, the nozzle is retracted while keeping the airtight holding state at the holding rod as it is.

[Effects of the Invention] Therefore, according to the present invention, the rim of the bag body has two nozzles,
Since both ends of the bag are pressed and held by the pressing bar provided on the holding rod in a state of being fully expanded, the rim of the bag body is pressed and held in a completely flat state without any wrinkles or the like,
Air extraction or gas filling can be performed smoothly and satisfactorily.

In addition, the heat-sealing can be performed in the same state, and the heat-sealed portion is not only finely finished, but also can be completely packaged without any wrinkles. Moreover, since the pair of gripping rods are provided with a gap and two pressure-contacting rods are provided at the front and rear, the bag body rim can be changed in position and held more stably at two places. is there.

Next, since air is extracted from the bag body at two locations by a pair of two nozzles, the movement of the air at the time of removal is made evenly in one direction and the bag body is extremely deformed. Without this, the air can be removed smoothly and satisfactorily.

In particular, since air is discharged while being located at both ends of the nozzle bag and with the mouth of the bag fully opened, deformation of the bag is prevented, and air can be extracted without causing wrinkles. , Can be done smoothly and completely.

Further, according to the present invention, the lateral movement of the nozzle for widening the mouth edge of the bag body is interlocked with the vertical movement of the holding rod, and the retracting movement of the nozzle at the time of heat sealing is interlocked with the vertical movement of the heat sealing rod. Therefore, a series of continuous operations of bleeding air, filling gas, and heat-sealing can be completed completely and reliably without any error.

Moreover, since the nozzle and the holding rod and the nozzle and the heat-sealing rod are all interlocked mechanically via a driving body such as a chain, the reliability of the operation is further doubled and at the same time, the failure occurs. It can be used for a long time without doing so.

Furthermore, since the left and right movement of the nozzle is controlled freely by providing a clutch, it is possible to perform vacuum packaging or gas filling packaging for any bag without selecting the size of the bag.
It is possible to continuously package various types of products without replacing parts.

Further, in the present invention, when the nozzle retracted backward at the time of heat sealing is returned to the front to prepare for the next packaging work, the nozzle is not pulled forward by the action of the spring as in the conventional case, and the nozzle is The nozzle is not slidably mounted in the sliding body consisting of a rectangular tube as in the past, but rather is slid back and forth on the guide rod via the nozzle base. And, it can be accurately returned to the original position.

Further, according to the present invention, the left and right movements are controlled by one clutch, instead of separately driving the left and right nozzles separately by using the two clutches as in the prior art to move the left and right nozzles separately. Are perfectly matched, and the nozzle can be opened accurately at a predetermined position in the center of the base.

Furthermore, the present invention is conventional. The sliding body is not slidably mounted on the four support rods so that the four corners are slidable, and the pair of sliders slides on the two support rods. Can be moved very accurately and smoothly, and as a result, the nozzle can be moved laterally accurately and smoothly.
