Abstract

PROBLEM TO BE SOLVED: To provide a packaging machine which can package an object to be packaged without using an excessive resin film. SOLUTION: The packaging machine 1 is designed so that a panel 7 carried from a feed conveyer 2 is carried to a receive conveyer 5 while being covered by and pulling a resin film 31, wherein every time the panel 7 passes, a terminal of the resin film 31 pulled by the panel 7 is heat-fused for bagging by a heat- fusion device 4. A holding roll 6 for holding the panel 7 in a space from the receive conveyer 5 is provided above a receive base end of the receive conveyer 5 so that heat fusion is possible with timing that the terminal of the panel 7 passes through heat-fusing devices 41, 42.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging machine for packaging the surface of a product such as a panel with a resin film.

[0002]

2. Description of the Related Art Generally, when products such as panels manufactured in a factory are shipped, the surface of the products is packaged with a resin film.

Conventionally, as shown in FIG. 3, as a packaging machine a for packaging this panel, an article c conveyed from a feed conveyor b is conveyed to a receiving conveyer e while covering a resin film d. It is known that a resin film d covered by a transferred object c is heat-sealed and bagged by a heat-sealing device f every time.

In the case of the packaging machine a, the conveyed object c itself, which is conveyed from the feed conveyer b, is conveyed to the receiving conveyer e while pulling over the resin film d. After it is stable and stable
The resin film d was heat-sealed. That is, the heat fusing device f is operated at the timing when the transferred object c is placed on the receiving conveyor e.

[0005]

However, as in the case of the conventional packaging machine a, when the resin film d is heat-sealed after the conveyed object c is securely placed on the receiving conveyor e, the conveyed object c cannot be removed. The extra resin film d is packaged in a state of being formed in a long strip shape on the end side. Therefore, there is a disadvantage that the amount of the resin film d used increases. In addition, the resin film d long formed in a strip shape on the end side of the transferred object c may cause a disadvantage such that a sensor such as a photoelectric tube may malfunction in a subsequent transfer process.

The present invention has been made in view of the above circumstances, and has as its object to provide a packaging machine capable of packaging an article to be packaged without using an extra resin film.

[0007]

A packing machine according to the present invention for solving the above-mentioned problems is provided with a feed conveyor for conveying an object to be conveyed, and a resin provided at a leading end side of the feed conveyor for supplying a resin film. A film supply device, a heat-sealing device provided on the conveyance tip side of the resin film supply device for heat-sealing the resin film, and a reception device provided on the conveyance front-end side of the heat fusion device for receiving an object to be conveyed Conveyor is provided, and the conveyed object conveyed from the feed conveyor is conveyed to the receiving conveyor while pulling over the resin film, and every time the conveyed object passes, the resin film pulled by the conveyed object is A packaging machine in which the end portions are heat-sealed by a heat-sealing device and packed in a bag,
A holding roll is provided at a position above the receiving base end of the receiving conveyor so as to hold the transferred object with the receiving conveyor, and the heat transfer is performed at a timing when the end portion of the transferred object passes through the heat fusion device. It is made to be wearable.

[0008]

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

FIG. 1 schematically shows the entire configuration of the packaging machine 1.
FIG. 2 shows a packaging process by the packaging machine 1.

That is, the packaging machine 1 includes a feeding conveyor 2, a resin film supply device 3, a heat fusing device 4, a receiving conveyor 5, and a holding roll 6, and a panel 7 conveyed from the feeding conveyor 2 is formed of a resin film. 31 for packaging.

Since the resin film supply device 3 and the heat fusing device 4 are provided between the feeding conveyor 2 and the receiving conveyor 5, an interval of about 400 mm is provided. A photoelectric tube 21 for confirming passage of the panel 7 is provided at the leading end of the transport of the feed conveyor 2.

The resin film supply device 3 is provided at a position immediately on the front end side of the transport of the feed conveyor 2. The resin film supply device 3 supplies the resin film 31 so as to block the leading end side of the feed conveyor 2. This resin film 31 is wound on rolls 30 provided above and below the feed conveyor 2,
The panel 7 is pulled by the panel 7 conveyed from the feed conveyor 2 and is fed out one after another.

The heat fusing device 4 includes a fusing table 41 slightly lower than the transport level of the feed conveyor 2 and the receiving conveyer 5, and ascends and descends from above the fusing table 41. And a heater 42 for fusing the resin film 31 therebetween. Since the operation of the fusing device 4 is performed based on information from the photoelectric tube 21, the heat fusing device 4 is provided at a position near the leading end side of the feed conveyor 2 where the photoelectric tube 21 is provided.

The holding roll 6 is adapted to move up and down in accordance with the panel 7 to which the feed conveyor 2 and the receiving conveyor 5 are conveyed.

Next, a procedure for packaging the panel 7 by the packaging machine 1 will be described.

First, the panel 7 conveyed by the feed conveyer 2 hits the resin film 31 located at the front end of the conveyer of the feed conveyer 2. And the heater 42, and is conveyed to the receiving conveyor 5 side.

Since the panel 7 is held between the receiving conveyor 5 and the holding roll 6 at the base end of the receiving conveyor 5, as shown in FIG. Even if only the position is placed, it is transported in a stable state. Therefore, even if the heat-sealing device 4 is not operated after the panel 7 is completely placed on the receiving conveyor 5 and stabilized, the resin film 31 is removed at the timing when the end of the panel 7 passes through the heat-sealing device 4. It can be heat-sealed. The timing of the heat fusion by the heat fusion device 4 is determined by the photoelectric tube 21 provided at the leading end of the transport of the feed conveyor 2.

As described above, when the resin film 31 is heat-sealed at the timing when the panel 7 passes through the heat-sealing device 4, as shown in FIG.
The panel 7 can be wrapped without using.
Therefore, the consumption of the resin film 31 can be suppressed and the packaging cost can be reduced. In addition, the panel 7 wrapped in this manner is a strip-shaped extra resin film 31.
Can be prevented from erroneously operating a sensor (not shown) provided in the transport process after the receiving conveyor 5.

[0019]

As described above, according to the present invention, the holding roll is provided above the receiving base end of the receiving conveyor so as to hold the transferred object with the receiving conveyor. The object is held between the holding roll and the receiving conveyor and stabilizes while riding on the receiving conveyor.
Therefore, even when the transported object does not completely ride on the receiving conveyor, the resin film can be fused by the fusing device at the timing when the end portion of the transported product passes through the heat fusion device. Thus, the transported object can be packaged without using an extra resin film.
As a result, it is possible to reduce the packaging cost by suppressing the consumption of the resin film, and it is possible to prevent the unnecessary resin film from erroneously operating the sensor and the like.
