[Detailed description of the invention]

[0001]

[Industrial application field] The present invention uses a packaging film,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for packaging leafy vegetables such as spinach in a bag.

[0002]

2. Description of the Related Art At present, bagging and packaging of vegetables, mainly leafy vegetables such as spinach, are performed manually. Therefore, a great deal of labor and time are required for adjustment work before shipping. A packaging device in this field, for example, a packaging device for vegetables and the like disclosed in Japanese Patent Application Laid-Open No. 62-94519 is a packaging device for spinach and the like, but is a device for winding spinach with a film and cannot be packed in a bag-packed state. In addition, it is not applicable to other vegetables (tomato, cucumber, potato, etc.) despite its complicated mechanism.

[0003]

[Problem to be solved by this invention] This invention promotes the adjustment work until the farmers' shipment and shortens the working time by packing vegetables in a bag-like form, and also improves the shelf life of the products,
The purpose is to reduce damage during transportation and improve hygiene.

[0004] The types of vegetables produced by ordinary farmers are leafy vegetables,
Because of the variety of cucurbits, eggplants, tuberous roots, and many other types, it is necessary to package these vegetables in a bag without damaging them, instead of using a dedicated machine.

[0005]

According to the present invention, a pair of roll-wrapped films are provided to face each other, and the films are welded by heat and joined to one sheet, and the article to be packaged is placed on the film. It is possible to ride, send the film by the same length, and in conjunction with sending the film, the packaged article can drop under its own weight, and after falling, within a set time, Vegetables characterized by being provided with a heat seal bar which can be fixed in three places, two in the vertical direction and one in the upper horizontal direction, except for one lower part where the film is closed, and can be formed into a bag shape. It relates to a packaging device.

[0006]

According to the present invention, a pair of roll-wound packaging films are provided facing each other and used in a state where they are heat-sealed and connected to one sheet. Each rolled film is fed by the same length by motor drive, dropped by the weight of the packaged product, sandwiched for 3 hours by a heat shield bar facing the heat shield bar with a drive motor, heat-sealed the three sides into a bag shape, and cut the upper part. This is a semi-automatic bagging and packaging device for vegetables and the like, which is provided with a belt conveyor at the place of drop and discharges.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to solve the above problems, in order to simplify the mechanism, the present invention heats a pair of opposing roll-wrapped packaging films into a single film, and places various vegetables in the center of the film. Then, when the switch is turned on, a pair of rollers (synchronizing each film) rotated by a driving device are used to feed the film to a certain length and move downward by the weight of the vegetables. After the film is stopped, a pair of heat welding bars are moved forward by the drive device, and the film is heat-sealed in three directions (two in the vertical direction and one in the upper horizontal direction (one in the lower part is already heat-sealed)) to sandwich the film. Form a shape. At the same time, the upper part is cut with a hot wire. Vegetables to be packaged fall into a bag of four-way heat-sealed film and fall downward. On the other hand, the heat welded and cut film on the top forms the bottom of the next bag. This is repeated.

In the above apparatus, in the case of spinach, which is a leaf vegetable, since the height and weight of the leaf vary depending on the season, the size of the bag is changed by the amount of the film to be fed out. The delivery amount is determined by the amount. Therefore, adjustment is possible even if the amount of spinach and the plant height change. On the other hand, since the temperature of heat welding differs depending on the environment where the apparatus is placed, this time, it is possible to cope with environmental changes by setting a time for applying a constant current to the heat (resistance) wire of the seal bar. Therefore, it is possible to follow the change of the product to be harvested depending on the season, change the size of the bag, and sufficiently cope with the environmental temperature change, so that the optimal bag packing can be performed.

The following is a description of the drawings. The drawings show one embodiment of the device of the present invention, wherein 1 is a frame. The roller 3 is rotated by the rotation of the drive motor 2 with the sending-out deceleration of the packaging film F rolled up on both sides of the frame 1, and the film F is sandwiched by its own weight to feed the film F without slack.

Both films F are driven by the film drive motor 2.
Rubber belt 5 on the pulley of the motor shaft 3
To obtain the same direction and the same amount of rotation.

A pair of film guide rods 6 are provided for stably placing the article to be packaged on the film F. Vegetables will be placed between the guide bars.

The feed amount of the film F is set by a timer 8 provided on the control panel 7, and the film drive motor 2 rotates. As shown in FIG. 1, the film F falls freely by its own weight of the packaged product and takes a shape sandwiched by the films.

At the same time as the film is fed, the seal bar 9 retreats to the state shown in FIGS. 5 and 6. The seal bar 9 is installed on the seal bar holding frame 10, and when the seal bar driving motor 11 is rotated in the counterclockwise direction, the seal bar 9 and the holding frame 10 are opened by their own weight, and hit the limit switch L1 and stop. At that moment, the seal bar drive motor 11 reverses clockwise and the seal bar 9 moves forward until it hits the limit switches 1 and 2.

The operation of the seal bar is as follows. The wire 12 is fixed to the seal bar 9 on the left side of FIG. 6 by a wire 13 and the pulley 15 for the motor for driving the seal bar is driven via the seal bar pulley 14 installed on the seal bar 9 on the right side. Rotate forward and backward in fan shape. Further, since the essential positions of each seal bar 9 are assembled by the gear 17 in order to cycle the seal bar 9, the right and left seal bars 9 can be moved synchronously.

When the seal bar 9 advances (closes), comes into contact with the limit switch L2, and a signal is input, a current flows through the seal bar 9. The time for flowing the current is determined by the timer 18,1
9 is set. The timer 18 is for vertical sealing and the timer 19 is for horizontal sealing. The transverse seals were individually provided for thermally welding and cutting the film F. The bag cut by the lateral seal bar 9 'naturally falls onto the belt conveyor 20, and rotates in the discharge direction at that moment to complete a series of cycles.

As described above, the mechanism is simplified and can be operated reliably. As a result of a test on vegetables, it was possible to pack the vegetables without damaging them because the vegetables were put on a film such as spinach, cucumber, tomato, potato and the like before being moved. In this test, one cycle time took about 8 seconds.

[0017]

[Effect of the Invention] The present invention has the greatest feature in that vegetables can be packed in bags. This is not possible with conventional technology.
Further, it can be manufactured at low cost, and the labor of the shipper can be saved sufficiently.
