Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is characterized in that by pivoting the arm downward, the crimping section at the tip of the arm presses the tape portions to be attached to each other against the heating section of the crimping table below. The present invention relates to an improvement in a banding machine that abuts between the two, that is, a banding machine using tape, and particularly relates to a banding machine that can be suitably used for bundling vegetables, flowers, and the like.

(Prior art) In this type of banding machine, the object to be bound is fed onto a support member so as to release the tape stretched between the tip of the arm and the tape presser on the crimping table, and then the arm is pivoted. The tip is moved downward, the tape is wound, and the heating section and the crimping section abut against each other, crimping and cutting the tape portion between them, thereby making the tape binding.

(Problems that the invention aims to solve) Conventional banding machines do not have any problems when binding vegetables and flowers with soft stems such as green onions and spinach, but when binding plants with hard stems such as chrysanthemums. During tying, the end of the tape held by the tape holder may come off due to the repulsive force of the bundled stems, resulting in a problem that the tying operation cannot be continued properly. Furthermore, flowers with such stiff stems had the disadvantage that they could not be tightly bound together.

The purpose of this invention is to solve the above-mentioned problems. Therefore, it is possible to sufficiently squeeze the objects to be bound, so that they can be bound without looseness, and the tape ends can be prevented from coming off even when tying flowers with hard stems. The purpose is to provide a band-wrapping machine that does not require a band-wrapping machine.

(Means for Solving the Problems) The banding machine according to the present invention includes an arm that pivots up and down about a fulcrum, a crimping table having a heating part that receives the abutment of the crimping part at the tip of the arm, and a crimping table. It includes a support member on which the bundle is placed, as well as a pressure lever located near and preferably juxtaposed to the support member, the pressure lever pivoting towards the crimping table as said arm pivots downward. Therefore, it includes a clamp arm connected between the pressing lever and the arm, and preferably there is an elastic body at an appropriate position on the clamp arm.

(Function) Therefore, when the arm pivots downward, the press lever pivots toward the crimping table via the clamp arm, and the pivoting of the press lever causes the object to be bound on the support member to be moved to the heated part of the crimping table. When the tip of the arm reaches the lowest end and the crimping part and the heating part abut against each other, the objects to be bound are pressed most strongly and bound without loosening.

(Embodiments of the invention) Next, embodiments of the invention will be described with reference to the drawings. 1 to 3 show a preferred embodiment of the present invention as a whole, in which 1 is a base whose upper surface is a table, a support 2 is fixed to one end of the base 1, A crimping table 3 is located at the other end of the table. Reference numeral 4 denotes a pivotable arm, the base end of which is pivotally fixed to the column 2 by a pin 5. A reel 6 for storing tape is installed at an appropriate position on the arm 4. The reel 6 is equipped with a tension loading device (not shown) so that the tape is drawn out with an appropriate tension. The tip of the arm 4 is linear and engages with the crimping table 3 when lowered. Further, near the tip of the arm 4 there is a roller 7 that contacts the tape. A heating part 8 for welding the tape is located at an appropriate position on the crimping table 3, and a crimping part 9 and a cutter are provided at the tip of the arm to abut against the heating part 8. In this embodiment, a crank member 11 is attached to the shaft 10 of the base 1, and a connecting rod 1 whose one end is pivotally fixed to an appropriate position of the arm 4 and whose other end is connected to the crank member 11.
2, the motor 13 connects the crank member 1 together with the shaft 10 via a transmission member such as a chain 14.
The arm 4 is pivoted by power.
A support member 15 on which objects to be bound are placed is installed on the crimping table 3.

As shown in FIGS. 1, 2 and 4, this banding machine includes a pressure lever 16 pivoted near a support member 15, and a clamp arm 17 connected between the lever and arm 4. is provided. The pressure levers 16 are preferably provided on both sides of the support member 15, and their upper parts above the pivot points 18 are juxtaposed to the support member 15. Each lever 1
6 is pivotally fixed by a pin 18 supported by the crimping table 3, and connected to one end of the clamp arm 17 by a pin 19 at its lower end. The other end of the clamp arm 17 is pivoted by a pin 20 near the bottom of the fulcrum 5 of the arm 4, as seen in FIGS. 1 and 5.

The clamp arm 17 is preferably provided with a spring 21 interposed at a suitable position as shown,
Thereby, the pressure exerted by the lever 16 on the objects to be bound can be alleviated. The portion of the clamp arm 17 associated with the spring 21 is bisected at 17', as shown in FIG.
2, one part 17a is fixed to the sheath 22 by a strut 23, and the other part 17b is surrounded by the sheath 22.
2, but its range of movement is limited by a bolt nut 24 secured to its portion 17b and by a slot 25 in the sheath 22, as shown in FIG. The spring 21 is a tension spring and is attached to a fixed pin 26 of the part 17b of the clamp arm.
and a screw 27 adjustably provided in the post 23, which at 17 abuts the two parts of the clamp arm 17 against each other.

Further, as shown in FIGS. 4 and 5, the crimping table 3 has a presser member 28 facing the support member 15.
It is preferable that a
It can prevent it from sticking out. The center of the holding member 28 is open so that the tape can pass therethrough.

In this embodiment, the roller 7 is connected to the motor 13.
The tape T is rotated in the direction of pulling up the tape T by the string-like belts 30 and 31 which are operated by the belts 30 and 31. 32 is a guide roller for the belt. A pinch roller 33 is located between the roller 7 and the tape extending therebetween, and the pinch roller 33 is located at the tip of a lever 34 which is pivotally fixed at a fulcrum 34a. Arm 4
As it descends, it comes into contact with the roller 7 and pulls up the tape.

When tying, as shown in FIG. 1, the tape is stretched between the tip of the arm 4 and the tape holder of the crimping table 3, and the objects to be bound are fed to the support member 15 in such a way as to let out the tape. turn on and operate the motor 13. As the arm 4 pivots downward due to the operation of the motor, the part of the arm 4 below the fulcrum 5 also pivots, so the clamp arm 17 moves in the direction of arrow A (the fifth
The upper part of the lever 16 is thus pivoted towards the heating part 8 of the crimping table, reaches the position shown in phantom line 16' in FIG. 5, and presses the article S to be bound. When the arm 4 reaches the lowest end, the crimping part 9 and the heating part 8
Press the strongest when they are in contact. Therefore,
Banding is performed by pressing the object to be bound and lowering the arm in one action. At this time, if there is a limit to the compression of the object to be bound, the spring 21 will reduce its length and the separation point 17' will move away, so the pressing lever 16 will move back.
Relieve that pressure. Note that other elastic bodies can be used instead of the spring 21. Further, this relaxation effect can also be achieved with other structures such as, for example, configuring the pressing lever 16 itself with a leaf spring.

(Effects of the invention) As described above, according to the invention, the objects to be bound are pressed toward the heating part that welds the tape during tying, so flowers with stiff stems such as chrysanthemums can be tied properly without loosening. It can be tied tightly and the tape ends will not come off. Therefore, it can be suitably used for binding flowers and vegetables with tape. It should be noted that the mechanism is simple, and since the pressing and binding of the objects to be bound are performed in one operation, there is an advantage that the binding can be done at high speed.
