[Embodiment of device]

 Hereinafter, the present invention will be described in detail based on the illustrated embodiments.

In FIG. 1, a simplified structure of an article packaging apparatus is shown, and 1 is an original fabric made of a plastic film. As shown in FIG. 2, it is a long flat tubular shape, such as polyethylene or polypropylene. It is made of the thermoplastic plastics, and is wound in advance in a roll shape and is rotatably held by the original fabric holding portion 2.

That is, the original fabric holding portion 2 has a support shaft 3 that rotatably holds the roll-shaped original fabric 1 by inserting it into the center hole of the roll-shaped original fabric 1, and the original fabric 1 that is fed out. Are guided to the feed roll 5 through the idle guide rolls 4 ...

The feed roll 5 is composed of a pair of rolls that rotate in the direction of the arrow while sandwiching the fed-out raw fabric 1 from both sides, and at least one roll is rotationally driven by a roll motor M.

A cutter 6 is arranged near the downstream side of the feed roll 5, and a heating seal portion 7 is arranged near the downstream side of the cutter 6.

The heating seal portion 7 has a receiving plate 9 having a heating portion 8 of nichrome wire (in FIG. 1), and a reciprocating pressure that reciprocally moves toward and away from the receiving plate 9 (at right angles). It consists of 10 parts.

Moreover, in FIG. 1, the cutter 6 and the reciprocating pressing portion 10 are reciprocally operated by the same actuator 12 via the connecting member 11. That is, the case where the actuator 12 is a fluid pressure cylinder is illustrated in FIG. 1, but this fluid pressure cylinder is alternately supplied with pressure fluid via the solenoid switching valve 13, and is indicated by arrows A and B. Then, it reciprocates.

The heat fusion pressing machine 15 is composed of an actuator 12, a switching valve 13, a fluid source (pump and motor, etc.), a connecting member 11, a pressing part 10, a heating part 8 and the like.

This heat fusion pressing machine 15 is held by the heat seal portion 7 by a predetermined dimension from the leading edge 1a of the raw fabric 1 which is arranged on the downstream side of the cutter 6 and is fed from the feed roll 5. The part 2 side-upstream side-is heat-sealed to form an open bag F (see Fig. 6). Prior to this heat fusion, the cutter 6 cuts C (see FIG. 6) slightly upstream of the heat fusion portion.

The time during which the reciprocating pressing unit 10 presses the original fabric 1 toward the receiving plate 9 and heats it--the time during which the heat fusion pressing machine 15 presses the original fabric 1 and heats it-- A timer 16 is provided to control the solenoid, and the solenoid of the switching valve 13 can be turned on and off by the timer 16.

The timer 16 can be adjusted in time by the setting means 17, and sets the length of pressing time for sufficient fusion according to the material, thickness, etc. of the material 1.

Further, in FIG. 1, a length dimension control means G is provided for controlling the roll motor M to determine the length dimension L for sending out the original fabric so as to be able to increase or decrease. That is, as shown in FIGS. 1 and 6, the length from the cut C to the next cut C corresponds to the length dimension L, which can be determined corresponding to the size (length dimension) of the article to be packaged.

As the length dimension control means G, the simplest one is that the length set in the digital counter is subtracted by the pulse signal from the encoder attached to the feed roll 5 and the feed is stopped by zero reset. To configure. Alternatively, as the length dimension control means G, a pulse motor may be used as the motor M to be integrally configured. Furthermore, as the length dimension control means G, another simple one is a foot switch operated by a person's foot, and by visually observing the length dimension L to be sent out, the foot switch can be turned on and off. Good.

From the viewpoint of handling, it is desirable that all of the components shown in FIG. 1 are provided in one portable base frame to make it portable. That is, it is desirable that the original fabric holding section 2, the feed roll 5, the motor M 1, the length dimension control means G, the cutter 6, and the heat fusion pressing machine 15 are all portable.

In addition, in FIG. 1, a sensor 18 for detecting the pattern (including characters, figures, and symbols) of the original fabric 1 is attached, and the cutting, the heat fusion position, and the relative position of the pattern are shown. It is also preferable to control in advance to be constant. In this case, the output signal from the sensor 18 is input to the dimension control means G (the circuit is not shown).

A magnet may be simply used as the actuator 12 (not shown).

Next, a method of packaging articles using the packaging device illustrated in FIG. 1 will be described. First, as shown in FIG. An original fabric 1 made of a long tubular plastic film is wound in a roll shape in advance and set on an original fabric holding portion 2.

In the state of FIG. 3, the product H (see FIG. 8 to FIG. 10) is fed out by a length dimension L corresponding to the size of the article H (see FIG. 8 to FIG. 10) (the feed roll 5 is rotationally driven by the motor M). , Suspend the sending of original 1

This feed dimension control is performed by the dimension control means G. When a foot switch is used, an operator (operator) judges by looking at the article H and switches the foot switch for an appropriate time. It is sufficient to step on the foot and rotate the motor M. Further, in the case of the dimension control means G using an electronic circuit and an encoder, the feed dimension can be increased or decreased by turning the knob or the like, or the article name and its length dimension can be preset by the setting input means (keyboard etc.). After inputting, and the operator (operator) presses the button of the article name, the feed of the length dimension L corresponding thereto is automatically given. Alternatively, a bar code may be attached to each article (product) in advance, and the bar code may be read by a reader, or only the length dimension L previously input to the dimension control means G may be correspondingly read. May be performed (by program control).

Next, as shown in FIGS. 3 to 4, when the cutter 6 and the pressing portion 10 are lowered simultaneously (by the operation of the actuator 12 in FIG. 1) as indicated by an arrow A, the cutter 6 is moved downward. In cooperation with the mana plate member 19, the raw material is cut into the length L, and the pressing portion 10 cooperates with the heating portion 8 to heat while pressurizing to perform the first heat fusion.

It is assumed that the timer 16 shown in FIG. 1 is set in advance to a time sufficient for the first heat fusion, and then the cutter 6 and the cutter 6 are pushed as shown by an arrow B in FIG. When the pressure part 10 is raised, as shown in FIG. 6, a one-sided opening bag F is obtained.

That is, the bag F obtained by such a bag-making process is substantially equal to the length dimension L from the leading edge portion 1 a of the original fabric 1 at a position of a slightly smaller size. Are sealed by heat fusion to form a sealed fusion-bonded portion 21 in the width direction. The cutting C is performed slightly upstream of the hermetically fused portion 21.

Next, as shown in FIG. 7, after the article H is inserted into the bag F having one opening and stored as shown by the arrow, (the upstream end and the downstream end of the bag F are reversed). As shown in Fig. 9, the opening edge 22 of the bag F is installed between the pressing part 10 and the heating part 8, and the pressing part 10 is lowered again as indicated by arrow A, and the second time is set as shown in Fig. 9. Heat fusion is performed (the sealing step is performed), and the article H is hermetically packaged. After that, as shown in FIG. 10, the pressing portion 10 is raised in the direction of the arrow B to take out the bag F ′ in which the packaging of the article H is completed. FIG. 11 shows a state in which the article H is thus completely packaged in a hermetically sealed manner.

As described above, if the first heat fusion bonding and the second heat fusion bonding are performed by the same heat fusion pressing machine 15, the equipment cost can be reduced and the equipment can be installed in a small space. It's done.

The basic operation will be described below collectively (or including other operating methods).

The roll-shaped original fabric 1 is mounted. The feed length is set by a digital switch (as the dimension control means G). Set the sealing time with timer 16. Start with the touch switch. The feed roll 5 feeds out the set length dimension and stops, and the cutter 6 and the pressing portion 10 descend and heat-fuse for the first time, and then rise (open). The article H is stored in the bag F. The opening edge 22 of the bag F is placed on the heating part 8 and the foot switch is operated by the foot to lower the pressing part 10 to perform the second heat fusion. (Although not shown, the cutter 6 and the pressing part 10 are different actuators so that only the pressing part 10 descends at this time, or the connecting member is composed of two parts and the solenoid pin is used. It may be configured so that it can be switched between the two states (integrated) and separated from each other by means such as).

However, according to this article packaging apparatus, it is not necessary to prepare various bags in advance in a store that sells food, daily necessities, miscellaneous goods, and other various articles.

In addition, a bag can be manufactured and used immediately (for packaging) when and when needed. At this time, since the size of the bag depends on the article to be packaged, there is no waste, and conversely, long wooden boards, wood, sticks, etc. can be easily packaged entirely. Further, only one heat fusion pressing machine is required, and the apparatus can be made compact.

Further, the length dimension control means G allows easy and reliable packaging of an article having a sufficiently long dimension according to the dimension (such as a long article) without waste. Also, the actuation of the actuator 12 enables (almost) simultaneous cutting and heat fusion. The structure can be simplified.

An operator such as a salesperson can easily determine the size (length dimension) of the bag by using the foot switch in accordance with the article to be packaged. Further, the size (length) of the bag can be easily set by the length control means G composed of an electronic circuit so that the bag has a size suitable for the product to be packed. In addition, it is convenient to be able to easily move to a place in a large store where packaging is required.
