Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables vacuum packaging of the packaged items with the packaging material while the conveyor is rotating by placing the packaged items in a packaging material on a part of the conveyor. The present invention relates to a rotary vacuum packaging device that enables the conveyor to be placed in a three-dimensional (two-dimensional) configuration, thereby reducing the installation area of the device so that the vacuum container components always rotate while maintaining a horizontal state. It is characterized by this.

2. Description of the Related Art Conventionally, a conveyor system as shown in FIG. 7 has been used as an apparatus for efficiently vacuum packaging (including filling with inert gas) objects to be packaged in packaging materials such as films, bags, and trays. That is, to explain Fig. 7, the upper surface of the machine base (1) (=belt conveyor (2) is installed together with the metal, and the i'+J' mr type box-shaped lid (3) is installed in a part above the conveyor. An appropriate number of packaging materials (5) containing items to be packaged are placed in parallel on the conveyor (2) at the position of the arrow (4).
When the conveyor (2) rotates, each packaging material (5) is conveyed to the bottom of the box-shaped lid (3), and immediately after that, the box-shaped lid (31) is lowered one step and transferred to the conveyor (2). ) to form an airtight vacuum area, and seal the opening of the packaging material within the vacuum area to vacuum package the packaged item. The packaging equipment in this building is in the lowered state. It is efficient because it is possible to arrange an appropriate number of packaging materials (5) on the belt conveyor (2) while vacuuming the inside of the Φ6 shape (3). As shown in Figure 7, vacuum packaging systems that require packaging materials to be transported horizontally or at a near-horizontal (-nearly inclination) inevitably require a large installation area.

In view of the above points, the present invention is designed to make the rotational movement of the conveyor three-dimensional while keeping the conveying surface of the packaging material horizontal, thereby reducing the installation area of the device. The central portion of the rotor, which is integrally connected through the rotor, is rotatably supported between the frames on both sides of the rotor via the central axis, and a plurality of rods are connected between the two side plates at a plurality of locations on the periphery of the rotor. Each of the rotating shafts is supported in a horizontal and rotatable state, and a planetary foil having the same diameter is fixed to one end of each of the rotating shafts, and a planetary foil having the same diameter as the planetary foil is fixed to one end of each of the rotating shafts. supporting a sun foil of a diameter on the central axis, setting the sun foil and the frame in a mutually immovable relationship, and connecting these sun foils and each of the planetary foils by engaging an endless chino; In addition, each of the rotating shafts (2) fixes the components on one side of the divisible vacuum box in a horizontal state, and supports the components on the other side of the divisible vacuum box on the frame so as to be vertically movable. First, an intermittent rotation mechanism is connected to the irj rotor so that the vacuum chamber component on each side is stopped below the vacuum tube component on the other side.

Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, the rotation 1 portion is constructed by connecting a pair of side plates t101uUl arranged on both sides at their central portions with a circular joint member, and the joint member U

The illustrated embodiment is constructed as described above, and its operation will be explained below.

In Fig. 1, input from the outside of the frame U crease rotates the 1-quintillion motion shaft (321), and when the crank pin 6υ revolves and the rotational power is transmitted to the Geneva by the action of the crank pin Gi, the Geneva... The integral rotor, that is, the head of both side plates 10) connected through the joint member ←υ, rotates intermittently around the central axis u21 by a quarter rotation. In this case, the center axis U remains fixed to the frame u3) and does not move, and the center axis of the thick @Teen wheel 4 is fixed to 21, so it does not rotate.

If they are formed in a one-to-one relationship, each planetary foil μQ... is 1
Since it rotates once per revolution, a plated deer fixed on the rotating axis μ-uniform always revolves while being kept horizontally, and the l
During the revolution, it stops at four positions.

Therefore, at one stop position of these boards 124),
When the packaging material (■) containing the object to be packaged is fed onto the plate, the packaging material is sealed at the topmost stop position by a vacuum box consisting of at241 and a lid (2!ω), and the vacuum box After being deaerated inside, the opening is melt-sealed.

The power for moving the lid (25) up and down is obtained from the driving cuff via the Rondo G41, and when the rotor rotates, the lid J is at the upper limit position. As shown in Fig. 3, a stop pin 651 is provided on the frame u3) on the back side of the device, and when the plate e force is interfered with by this stop pin 6ω during revolution and tilts, the Packaging products are automatically slid off and removed.

In addition, No. 6. The diagram shows an example in which the relationship between immovable elements and rotation is different from that in Figure 1 (two configurations).

That is, in FIG. 6, the frame is rotatably supported via a center mttav ball bearing (4tll t4tj), while the side plate (101) is supported by a knock pin (4υ (4υ) The solar foil QQ is fixed to the east of the frame u through screws (421t421 .

However, since the frame side and the sun foil (7) are in a mutually immovable relationship, each planetary foil 416)...
The structure is similar to the embodiments shown in FIG. 1 and FIG. 6 in that it is configured to rotate with respect to the rotor via... Also, even if a belt is used instead of the endless change 4 in each embodiment, the intended purpose can be achieved, so the "cheno" described in the claims
is defined as including belts, strings, or both wheels. Furthermore, the horizontal state of the vacuum box component u4) is defined as including a slight inclination. Further, as shown in FIG. 5, it is optional to configure three or more rotating shafts (2).

As described above, the rotary vacuum packaging device of the present invention rotatably supports a rotor provided with a pair of side plates on both sides of the frame through the center cuff, and rotates a plurality of rotating shafts between these side plates. 2. While fixing planetary foil enclosures of the same diameter to the ends of these rotating shafts, a sun foil (2) of the same diameter as the planetary foils is fixed to the frame in a mutually immovable relationship. The sun foil (2) and each of the planetary foils 1
