Description

[0001]
[Industrial application fields]
The present invention relates to a leaf vegetable bagging apparatus that inserts leaf vegetables such as spinach and spring chrysanthemum into a bag such as a plastic bag and performs bagging.
[0002]
[Prior art]
In recent years, leaf vegetables are being shipped from farmers to markets after being packaged in small portions.
In order to efficiently carry out bagging of leafy vegetables, for example, a packaging device described in Japanese Patent Application Laid-Open No. 6-191508 has been proposed. In this packaging device, a large number of empty bags having ears are arranged on the receiving plate in a state of being suspended by the engagement holes of the ears, and after opening the bag mouth with a blower, leaf vegetables are put into the bag from the stockholder. It is inserted by hand, and the bag is cut off from the tear line.
[0003]
This packaging apparatus has a drawback that when leafy vegetables are manually inserted into the bag, the leafy vegetable stock hits the inner surface of the bag and is bent or caught, making it difficult to enter.
Japanese Patent Application Laid-Open No. 6-1316 discloses a bagging method and a bagging device for leaf vegetables, but the main part is provided with a funnel that goes up and down in addition to the above-described configuration, and leaves the leaf vegetables in the bag by hand. Instead of inserting, the funnel enters the bag with the leaf vegetable inserted in the funnel, leaving the leaf vegetable in the bag and pulling out only the funnel upward.
In this bagging device, leaf vegetable stocks and funnels may be caught inside the bag as in the case of the packaging device described above, or the leaf vegetables may be pulled out of the bag together with the funnel when the funnel is pulled out of the bag. Yes, the funnel is dangerous for the operator.
[0004]
[Problems to be solved by the invention]
The present invention proposes a bagging device that allows leafy vegetables to be smoothly inserted without being caught on the inner surface of the bag when the leafy vegetables are directly inserted into the bag by hand without using an instrument such as a funnel.
[0005]
[Means for Solving the Problems]
In the present invention, in a bagging device that holds an empty bag in an open state and inserts leaf vegetables held by hand from the opening side into the bag, a bag take-out mechanism 2 that takes out one empty bag from the bag container 1; a bag opening holding mechanism 3 for holding the bag the bag mouth of the empty bag taken out in the take-out structure 2 in an open state, the liquid into the bag provided with a liquid blowing mechanism 4 blowing in the mist, the liquid blowing mechanism 4 The pipe 27 having the liquid jet 25 and the air jet 26 is configured to be reciprocally movable by the electric cylinder 28 toward the approximate center above the empty bag , and the pipe (27) is set to the approximate center of the bag mouth. the moved, from the air ejection port 26, first after the blowing air only into the empty bag in blowing the liquid from the liquid ejection ports 25, further after returning pipe (27) to the original position, to insert the leaf vegetables Leafy vegetable bag characterized by It has a structure of the eye apparatus.
Further, the leaf vegetable bagging apparatus is characterized in that the liquid to be blown into the bag is water.
[0006]
[Action and effect of the invention]
Even if leaf vegetables touch the inner surface of the soft bag and get caught when inserting the leaf vegetables into the bag, the liquid that forms a mist and adheres to the inner surface of the bag makes the leaf vegetable slippery and prevents it from being caught. Even so, it can be smoothly inserted to the bottom.
If it is the said bagging apparatus, since an operator only has to hold and insert a predetermined amount of leaf vegetables into the bag opened by the bag opening holding mechanism 3, the working efficiency is improved.
If air is blown into the empty bag first to inflate the bag and then the liquid is sprayed in a mist, the mist will adhere evenly to the inner surface of the bag. Can be inserted smoothly.
In addition, if the liquid sprayed in the form of a mist into the bag is water, it will also replenish the leafy vegetables, and the leafy vegetables will be fresh and fresh.
[0007]
【Example】
Next, a leaf vegetable bagging apparatus embodying the present invention will be described with reference to the drawings.
A bag opening holding mechanism 3 is provided at the center of the upper portion of the square box-shaped machine frame 5, and a bag container 1 for storing a large number of empty bags and an uppermost empty bag in the bag container 1 are bonded inside. A bag unloading mechanism 2 for supplying the sheet to the one-sheet unloading bag opening holding mechanism 3 is provided, and a liquid blowing mechanism 4 for blowing the liquid into the opened bag in the form of a mist on the side of the external bag opening holding mechanism 3 is provided. Yes.
First, from the inside of the machine frame 5, the bag container 1 is a container for storing a large number of empty bags made of square or trapezoidal plastic bags, and the upper side is opened. 8 is inclined and is moved toward the center, which is the rotation range of the take-out arm 9, when the bag is supplied.
[0008]
The take-out arm 9 is pivotally supported by the support shaft 11 to the machine frame 5, and when the bag is taken out, the contact portion 10 at the tip comes into contact with the contact portion 10 near the bag opening of the uppermost empty bag in the bag container 1. The empty bag is attached to one sheet with a toroid-shaped adhesive provided, taken out, and is lifted and supplied below the bag opening holding mechanism 3.
Below the bag opening holding mechanism 3, a discharge chute 12 inclined toward the take-out port 13 provided on the side of the machine frame 5 is provided, and the leaf vegetables packed in the bag slide toward the take-out port 13 with the momentum of dropping. I try to come out.
[0009]
As shown in FIG. 2, the bag opening holding mechanism 3 has an operation having a round hole 16 having substantially the same diameter as the round hole 15 above the round hole 15 provided in the horizontal support base 14 provided in the upper part of the machine frame 5. The panel 17 is elastically supported upward by a support rod 18 provided at four equal positions around the round hole 16 and a spring 19, and the engagement rod 19 protrudes toward the center of the round hole 16 on the lower surface side of the operation panel 17. It is supported by the support shaft 20 in such a state. The engagement rods 19 are provided at six equal positions around the round holes 16 and are held horizontally by the spring 21. When the operating plate 17 is lowered toward the support base 14, the end of the spring 21 is moved. The engagement bag 19 rotates in an obliquely outward direction from the lower side in contact with the protrusion 22 provided on the support base 14, engages with the inner side of the opened bag mouth, and opens the empty bag in a state of facing vertically downward. Hold on.
[0010]
Reference numeral 23 denotes an opening arm, which is horizontally reciprocated so that the abutting portion 24 is opened by adhering the outside of the bag mouth with the abutting portion 10 of the bag take-out arm 9. The engagement bag 19 is engaged from the inside to the bag mouth thus opened, and the empty bag is suspended.
The liquid blowing mechanism 4 provided on the outer side portion of the bag opening holding mechanism 3 is configured such that a pipe 27 having a liquid ejection port 25 and an air ejection port 26 is an electric cylinder 28 and is directed from the side of the operation panel 19 to the center of the round hole 16. To reciprocate. 29 is an air compressor, 30 is a metering discharge pump, and 31 is a liquid tank.
[0011]
32 is a bag removal switch. When this bag removal switch 32 is pressed, the bag takeout mechanism 2 causes the bag opening holding mechanism 3 to hold the empty bag in an open state, and the pipe 27 of the liquid blowing mechanism 4 moves to the center of the bag opening. Move to make liquid mist in bag and return to original position.
When an operator manually inserts leaf vegetables into the bag and presses the bag removal switch 32 again, the operation panel 17 of the bag opening holding mechanism 3 rises to release the bag filled with leaf vegetables and drop it onto the discharge chute 12. It is discharged out of the machine frame 5 from the outlet 13, and the empty bag is held in the bag mouth opening holding mechanism 3 again, and the liquid blowing mechanism 4 blows liquid into the bag mouth so that the leafy vegetables can be inserted and waits.
