Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to improvements in a vegetable binding machine for binding relatively soft vegetables such as spinach and green onions into required bundles.

This type of vegetable binding machine conventionally uses a resin film such as polypropylene or polyester as a base material, and uses adhesive tape coated with an adhesive on the lower side to wrap vegetable bundles into small bundles for retail sale on a vegetable binding table. Since it was fixed by turning it, the adhesive ended up adhering to the vegetable side, which was not sanitary and had the disadvantage that the adhesive was expensive. For this reason, some methods have been considered to fasten with staples, but
This method is less practical because there is a danger that the needles may get mixed in with the vegetables or that the needles may poke one's finger during handling.

In addition, conventional vegetable binding machines use a binding arm that rotates in the forward and backward direction with respect to a vegetable binding table, and pulls out the tip of the adhesive tape hanging from this arm and sets it on the table. The vegetable bundles are stacked on top of this, and then the binding arm is rotated to wrap the adhesive tape around it. With this configuration, a new adhesive tape is applied each time - times of binding operations are completed. The adhesive tape set on the vegetable binding table must be pulled out onto the vegetable binding table and set again, which requires a complicated method.Additionally, when tying, the adhesive tape set on the vegetable binding table must be held in a fixed position, so the tip of the tape must be pulled out and reset. It is necessary to restrain the adhesive tape by some means, and as a result, the tip remains as a scrap after binding and is discarded, resulting in a poor yield of adhesive tape and making it impossible to use it economically.

The purpose of the present invention is to eliminate such difficulties and provide a practical and sanitary vegetable binding machine, in which a drive roll for clamping the tip of the binding tape is installed at a suitable position in the front of a vegetable binding table. The back part is equipped with a binding arm that rotates downward so as to fit over the vegetable bundles placed on the table, and the thermoplastic binding tape pulled out from the binding tape feeding part is tied to the The tape is hung on the arm and the tip of the tape is clamped to the pair of clamping drive rolls, and a thermal welding means is formed between the open free end of the binding arm and the right side of the binding that abuts in the straddling state. In the present invention thus configured, the binding and fixing of vegetable bundles with the binding tape does not rely on the adhesive applied to the binding tape (instead of relying on the adhesive applied to the binding tape (instead of relying on the adhesive applied to the binding tape), Since it relies on heat welding, vegetables can be tied together hygienically and inexpensively, and there is no danger to the human body, which is the case with staples.

Furthermore, if the drive roll pair that clamps the tip of the binding tape during thermal welding, that is, binding, is driven in one direction to eject the tape, and a tensile force is applied to the area of the binding tape to be thermally welded, this area will be separated. The binding tape portion wound around the vegetable bundle is easily separated from the original binding tape portion. Therefore, a dedicated cutting means is not required, the structure is simplified, and a vegetable binding stand can be provided.

Furthermore, if the heat-welded portion of the binding tape is partially driven by driving the drive roll pair, the tape end portion clamped by the drive roll pair is hung on the binding arm, as will be clear from the description of the embodiment below. It is thermally welded to the unused binding tape portion and remains as a single piece. Therefore, there is an advantage that no scraps of the binding tape are produced each time the binding tape is bundled, and the entire amount of the binding tape can be used economically.

Furthermore, as mentioned above, the unused binding tape part is automatically connected to the tip of the tape that is clamped to the pair of drive rolls by heat welding, so that the binding tape can be attached to the vegetable binding table every time the binding is performed, unlike conventional methods. There is no need to pull it out and reset it again.

Therefore, when tying vegetables, place the vegetable bundle on the vegetable tying stand.
Then, simply by repeating the operation of rotating the binding arm downward, the vegetables can be bound one after another, thereby providing an easy-to-operate and highly efficient vegetable binding machine.

In the conventional type of adhesive tape, it is necessary to roll it up so that the adhesive surface is not exposed to the outside, and then roll it out to the binding arm side. In other words, it is limited to the roll-wound type, but in order to reduce the frequency of tape replacement in the vegetable binding machine and reduce the number of times of tape replacement, increasing the amount of tape wound in the roll-wrap will increase the roll diameter. becomes larger in diameter, and various restrictions are added. For example, in order to allow for an increase in the tape roll diameter, the tape roll loading section must have a wider space, which is not preferable in providing a compact vegetable tying machine. However, if the adhesive is not required as in this %Q, the method of winding this binding tape is free, so a method of winding it evenly around the entire circumference, such as so-called traverse winding, can be adopted. Although the winding amount is long, it can be wound small. Therefore, while designing the vegetable binding machine to be compact, it is possible to use binding tape.
This dramatically increases the amount of tape that can be wound, reduces the frequency of tape replacement, and eliminates the hassle of tape replacement.

Hereinafter, the details of the present invention will be explained based on the drawings in which one embodiment of the present invention is shown holding target vegetables.In FIG. 1 and FIG. In addition, the upper part of the pedestal 2 is provided with a binding pedestal 8.
A pair of drive rolls 5.6 for clamping the leading end of the binding tape is mounted on a shaft near the front surface of the tape and with a required gap 4 in between. The pair of drive rolls 5 and 6 are arranged in front and behind each other with their surfaces in close contact with each other, and are connected to a drive means such as a motor or a human drive means (not shown), and are rotationally driven. Ru. At the rear of the binding table 8, a support post 7 is erected on the base 1, and a binding arm 8 having a substantially semicircular appearance is pivotally connected to the support post 7 at one end thereof so as to be freely movable up and down. 9 indicates the support shaft which is the center of rotation. This binding arm 8 is designed to be rotated by gripping a handle 10 connected thereto, and is rotated downward at the time of binding to attach the vegetable bundle A placed on the binding table 3 as shown in Fig. 2. straddle. Further, when the binding arm 8 is straddled, the open free end 11 of the binding arm 8 is configured to be inserted into the above-mentioned cavity 4, and the crimp plate 12 is fixed to this open free end 11, and the mount 2 of the cavity 4 is An impulse heater (heating plate) 18 is provided on the top, and these two parts 12 and 13 constitute a thermal welding means. This in/solus heater 18 is used for welding thermoplastic resin, and heats it by passing a large current only for a very short period of time for sealing. In addition, several winding rolls 14, 14 for hanging binding tape are supported on the side of the binding arm 8. The further back position of the binding arm 8 is a binding tape loading part, that is, a binding tape feeding part 15, and the core holder 1
6 is loaded with a winding bundle 18 of binding tape 17. In the figure, the winding bundle 18 is shown as a roll type wrapped in a paper tube for convenience, but it is of course free to convert to traverse winding or the like. The binding tape 17 is made of thermoplastic resin, such as polyolefin (polypropylene, polyethylene).
In order to bind the vegetable bundle A softly and prevent it from being damaged, it is preferably made with low foaming. In addition, the dimensions of the binding tape are width 5-20 m/m, thickness 0.05-0.
．． A range of 8 m/m is suitable for use, but the range is not particularly limited.

In use, pull out the binding tape 17 from the winding bundle 18 as shown in FIG.
．． 14, its tip 17a is sandwiched between a pair of drive rollers 5 and 6 as shown by a chain line. Then, pass the vegetable bundle A between the binding arm 8 and the binding table 8, press it against the binding tape 17, pull out the tape 17 further, and place it on the tape and the binding table 3. Next, as shown in FIG. Binding arm 8
Turn it so that it covers the vegetable bundle A. As a result, the bundle 17 is wound around the vegetable bundle A. Also f-7 in Figure 3
A detection means (for example, a switch) not shown in the figure detects that the binding tape 17 is sandwiched twice between the crimp plate 12 and the impulse heater 1B, and the binding arm 8 is rotated. Knowing this, the impulse heater 13 is energized, so that the double portion 19 of the binding tape 17 is thermally welded and integrated, and the used binding tape portion 17b wound around the vegetable bundle A is closed in a ring.

During this thermal welding operation, the drive roller pair 5.6 is rotated in the direction of the arrow in FIG. 8 to advance the tape tip 17a by several m/m. As a result, a tensile force is applied to the double portion 19, and the integrally heat-welded portion is partially cut off as shown in FIG. 4, and the used binding tape portion 17b is separated from the unused binding tape 17. Since the tape tip 17a is connected to this unused binding tape 17, the bundled vegetable bundle A can be taken out by letting the binding arm 8 escape upward and opening the binding table 8. Also,
In this state, the tape tip 17a is integrally connected to the unused binding tape 17 as described above, and this tape tip 17a is sandwiched between the pair of guide rolls 5 and 6.
This means that the state has returned to the state shown by the chain line in FIG. 1, and the bundling work can be continued by carrying the vegetable bundle A onto the bundling table 8 again.

The present invention has been described above, and as is clear from the description of this embodiment, the intended purpose has been satisfactorily achieved.
