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 is conventionally made of polypropylene.

Adhesive tape with a resin film base material such as polyester μ and an adhesive coated on the negative side of the base material? use.

Since the vegetable bundles for retail sale were wrapped and secured using a vegetable binding table, the adhesive adhered to the vegetable side, which was not sanitary and desirable, and had the disadvantage that the adhesive was expensive. A stapler is being considered for this purpose, but will the needles get mixed in with the vegetable bundles, or will the needles touch the fingers during handling? It is less practical due to the danger of being poked.

In addition, conventional binding of vegetables, etc. uses a binding arm 2 that is rotated in the forward and backward direction with respect to the vegetable binding table, and the end of the adhesive tape that is hung from this is pulled out and set on the Hokki table 5.
Four bundles of vegetables are stacked on top of this, and then the binding arm r is rotated to wrap the adhesive tape around it. With this configuration, a new adhesive tape is applied each time - times of the binding operation are completed. ? There was a problem in that it had to be pulled out onto the vegetable binding table and set again, which required a complicated method. In addition, in order to keep the adhesive tape set on the vegetable binding table in a fixed position during tying, the tip of the tape must be restrained by some means, so this tip remains as a scrap after tying, which is discarded. As a result, the yield of the adhesive tape was poor, making it impossible to use it economically.

The present invention aims to eliminate such difficulties and provide a practical and hygienic vegetable tying machine, and furthermore, it is an object of the present invention to provide a vegetable tying machine that can automatically perform this practical and hygienic tying work.
What to offer? Main focus.

That is, in the present invention, a pair of drive rolls r are provided at a proper position in the mJ section of the binding table, and a binding arm is provided at the back position and rotated downward so as to fit over the wild bundles placed on the white ball. And 2 binding tape feeding parts and binding tape? Hang the binding arm so that its tip is sandwiched between the drive roll pair, and heat weld between the open free end of the binding arm and the white side of the binding, which are in contact with the straddle-like lock. means? The first detection means detects that the vegetable bundles are placed on the binding table, and the binding arm? The binding arm is moved to the binding operation, the binding posture is detected by the second detection means, the heat welding means is energized, and the binding arm ? Along with making a double movement, is the drive roll recorded? Feed a small amount and detect when the return movement of the binding arm is completed with the detection means of Kintetsu 3.
The present invention is characterized in that it is a vegetable binding machine that can be stopped.

With this structure, the binding and fixing of the vegetable bundles using the binding tape does not rely on the adhesive applied to the binding tape, but instead relies on heat welding of the thermoplastic bundles using the heat welding means. r Can be tied hygienically and inexpensively,
Moreover, it eliminates the danger to the human body that is associated with using staples.

In addition, during thermal welding and binding, the drive roll r holding the tip of the binding tape (r) and the binding arm move slightly in the tape ejecting direction in conjunction with the return movement of the binding arm to move the binding tape to the hot bath area. Since the tensile deer 2 is applied to the container and the portion is divided into two and cut, the binding tape portion wound around the vegetable bundle can be easily separated from the original binding tape portion. Therefore, a dedicated cutting means is not required, the structure is simplified, and the vegetable binding stand can be provided at a low cost.

Furthermore, by driving the pair of drive rolls, the bundled chives are heated I@
When the attachment part R is divided into two parts, the tip end of the tape sandwiched between the pair of drive rolls is thermally welded to the unused binding tape part hung on the binding arm, as is clear from the configuration of the embodiment described later, leaving 9 parts. , one hit. Therefore, there is an advantage that no scraps of the binding tape are generated each time the binding tape is bundled, and the entire amount of the binding tape r can be used economically.

Moreover, as shown in , the unused binding tape part is automatically connected to the tip of the tape sandwiched between the pair of drive rolls by heat welding, so that the binding tape can be attached to vegetables every time the binding is done as in the past. I'm worried about the hassle of having to pull it all the way to Taipei and reset it.

Therefore, when tying vegetables, place them on a sheep bundle and put them on a vegetable tying stand.
Next, by repeating the operation of rotating the binding arm r downward, the vegetables can be bound one after another, so that it is possible to provide a vegetable binding machine r that is easy to operate and has high performance.

In particular, the present invention is applicable from the time when the vegetable bundle is placed on the binding table as described above until the binding operation is completed and the binding arm returns to its original position. Since this is done automatically, the labor involved in manual operations is further reduced, and the bundling work can be performed with even higher efficiency.

Hereinafter, details of the present invention will be explained based on drawings showing one embodiment of the present invention. In FIGS. 1 and 2, a fixed block 2 is provided at a position near the front of a base plate l, and A welding table 8 is provided, and a pair of driving rolls 4 and 5 for clamping the tip of the binding tape is mounted on the front side between the welding table 8r, and a vegetable binding table 6 is installed on the rear side.
This binding stand 6 is equipped with a fixed block 2
It is attached to l+ so that it can move northward via the axis 7, and is maintained in the horizontal position shown in the drawing by the tension spring 8, and is rotated slightly downward by the load when Yasai Higashi A2 is placed on this bundling platform. Accordingly, F7Q is configured so that the protruding piece 9 turns on the switch lOr, which is the first detection means. This switch 10 is for turning on the forward/reverse shaft drive (to be described later). At the rear position of the binding table 6, a column 11 is erected on the base 1, and a binding arm 12 is attached to this. It is pivoted to the support 111118 so that it can move freely over L. A sector gear 14 is fixed to the end of the support shaft 13, while the base l
is equipped with a forward/reverse drive motor, that is, a binding arm drive motor 15, and a gear 16 fixed to its output shaft 15a and a sector gear 14 are interlocked and connected via an intermediate reduction gear 17r. Therefore, by starting the motor 15, the binding arm 1
2 is rotated, and at the time of binding, it is rotated downward and fits over the vegetable bundle A placed on the binding table 6, as shown in FIG.

At the rotating tip of the binding arm 12, there is a cylindrical part 18 that guides the binding tape and passes it through.
During binding, the cylindrical portion 18 is brought into contact with the surface of the welding table 3J, as shown in FIGS. Impulse heater 20 for melting table 3 fill
A hot bath core means is provided at 19.20.

This impulse heater 20 is for welding thermoplastic (2) fat. It heats up by passing a large current through it for a very short period of time. In the illustrated example, the crimp plate 19Th is a separate member from the cylindrical portion 18, but the cylindrical portion 18 may also serve as the crimp plate, and similarly the welding table 3 itself may be an impulse heater. You are also free to use IN 51-j to double as IN 51-j. 21 is on the opposite side from the support 11 and the binding arm 1
A guide roll 22 is pivotally supported at the tip of the support rod introduced to the back of the roller 2. Further, the back position of the binding arm 120 serves as a binding tape loading section and a pick binding tape feeding section 23, and a wound bundle 26 of the binding tape 25 is loaded onto a pedestal 24 at the core. The binding tape 25 is made of Netsucho plastic resin, for example, polyolefin (polyethylene, polyethylene), and is used for vegetable bundles? In order to bind it softly and prevent damage, it is preferably low foamed. In addition, the dimensions of the binding tape are width 5~29 m/sn, thickness 0.05~
A range of 0.8 m/m2 is preferably used, but there is no particular limitation to this range. 27 indicates the rotation center axis r of the winding bundle 26.

FIG. 3 is an enlarged view of the essential parts on the opposite side of FIG. A switch 29, 30 is mounted on the north face of the base plate 1, and the switch 29, 30 is sandwiched between the lever 28 and operates the second and third detection means, and the binding arm 12 is rotated to the bottom dead center. As a result, the switching lever 28 kicks one switch 29, and as the switching lever 28 moves back to the north dead center, the switching lever 28 kicks the capacity switch 30r. It has a function r to stop the arm drive motor 15. Also, one of the rolls 4 of the pair of drive rolls 4.5 described above is equipped with a ratchet tIN8t2.
A driven link 32 is provided, and the unwinding bundle 2
Ratchet mechanism 38 also on the rotation center axis 27 of 6? These driven links 82, 84 and the switching lever 28 are connected by connecting rods 85, 86 through universal joints 39, 39, respectively, so that both driven links 82, 84 and the switching lever 28 are connected to each other by a connecting rod 85, 86 through a universal joint 39, 39, so that both driven links 82, 84 and the switching lever 28 are connected to each other by a connecting rod 85, 86 through a universal joint 39, 39. Links 32.84 are adapted to pivot accordingly. At this time, in the driven link 821tll, the ratchet mechanism 3 only when the connecting rod 35 is pushed in the direction of the broken line arrow in FIG.
A so-called binding tape minute feed means 7W4 is provided which applies a rotational force to the driving loaf 4 through the 1r. In this direction of rotation, the driving roll pair 4.5 is attached to the tip 25ai of the binding tape 25.
Therefore, the rolls 4 and 5 are assumed to be interlocked with gears, although not shown. In addition, the driven link 8
41tll, the rotation center shaft 27 and the winding Q are connected via the ratchet mechanism 33 only when the connecting rod 36 is pulled in the direction of the solid line arrow in FIG.
l) It is configured to rotate the bundle 26 and feed it out to the binding tape 25i-required length binding arm 12 side.

Next operation? This will be explained with reference to the control block diagram in FIG. 6 and the flowchart in FIG. In FIG. 6, 37 is a timer.

As shown in FIG. 1, the binding tape 25r is pulled out from the winding bundle 26, and once wrapped around the guide roller 22 at the tip of the support rod 21, the tape is passed through the cylindrical portion 18Th of the binding arm 12 and the tip 25r is pulled out from the winding bundle 26.
8 is placed between the drive roller pair 4.5 as shown by the chain line.

Then, seven vegetable bundles A are passed between the binding arm 12 and the binding table 6! ]1'' is pressed against the binding tape 25, and while pulling out the tape 25 further, it is placed on the tape and the binding table 6.

Then, in step 41 of FIG. 7, the binding table 6 is moved downward by the weight of the vegetable bundle, and the switch 1, which is the first detection means, is activated.
0 is turned on, and therefore the drive motor 15 is driven in the normal rotation at step 42, and its output is changed to gears 16→17→14? Then, the binding arm 12 is rotated downward by inputting it to the support shaft 13.
1II. As a result, as shown in FIG. 2, the binding arm 12
is rotated so as to cover the vegetable bundle A, and at the same time, the binding tape 2111 is wound around the vegetable bundle A. At this time, as the binding arm 12 rotates downward, the connecting rod 36 is pushed in the direction of the solid arrow in FIG. Since the rotational force in the unwinding direction is input, the binding tape 25 will be wound around the vegetable bundle A without loosening due to this unwinding. Also, as shown in Fig. 4, the binding tape 25 will be crimped at the bottom dead center of rotation. The binding tape 25 is double sandwiched between the plate 9 and the impulse heater 20.

Further, at this rotational bottom dead center, the switch 29, which is the second detection means, is turned on in step 43, and therefore, in step 44, the drive motor 15 is stopped and the state shown in FIG. 4 is maintained, and in step 45 Since the timer 37 and the impulse heater 20 are energized in parallel, the double portion 88 of the binding tape 25 is thermally welded and integrated, and is wrapped around the vegetable bundle A. When the used binding tape portion 25b is closed in a circular shape, the timer 8
7, after the time required for thermal welding has elapsed, in step 46, the drive motor 151 is reversely rotated and the supply to the impulse heater 20 is stopped. Therefore, the binding arm 12 starts to move backward, but the backward force at this time is inputted to the drive roll pair 4, 5 through the connecting rod 35 → driven link 82 → back working machine flt 31k, causing these to rotate. Then, the tip of the tape 25a is moved slightly in advance. As a result, double portion 38
A tensile deer acts on the part, and the part heat-welded to -4 becomes the fifth part.
It is divided into two parts as shown in the figure, and the used binding tape portion 25b is separated from the unused binding tape 25, and the tape tip 25a is connected to this unused binding tape 25, and the tape is released toward the binding arm 12'Ich and bound. By opening 6 tables, 6 tied vegetable bundles Ak6 can be taken out. Dimensions. In this state, the tape tip 25B is integrally connected to the unused binding tape 25 as shown in 9.
5a is clamped by the driving row A/pair 4 and 5, so the situation returns to the chain line in Fig. By doing so, the bundling work can be done continuously. Then, as the binding arm 12 moves back, the switch 3 is turned on by the detection means @3 in step 47.
0 is turned on, the motor 15 is stopped in step 48, and -
The tying operation is completed.

As is clear from the description of this embodiment, this invention has successfully achieved its intended purpose.

Note that the switch IO, which is the first detection means, can be changed to a micro switch, a photoelectric switch, or a new foot switch of the foot type.
