Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a binding device used for binding objects such as vegetables and flowers with tape.

(Prior Art) Conventionally, an adhesive tape has been used which extends from a tape reel, passes through the tip of a binding arm whose base is pivotally mounted on a base, and has one end held on one side of a crimping table provided on a base. is wound around the object to be bound on the other side of the crimping table, the wound end is crimped and cut on the crimping table in association with the tilting movement of the binding arm, and the cut end of the tape is There is known a binding device for binding objects to be bound with tape, which is held on one side of the crimping table.

A conventional binding device of this type is shown, for example, in FIGS. 3 and 4 (see Utility Model Application No. 49-7030).

In FIG. 3, the holder b of this binding device has a receiving part a on which the bundled items are placed, and the end of the operating frame d having the handle c is pivotally attached to the receiving part a side of the holder b. A recessed portion is formed on one side.

FIG. 4 shows an enlarged configuration diagram of the recessed portion during the bundling operation, and the recessed portion e is provided with a cutting blade g whose blade edge f is directed upward at the center portion of the bottom surface thereof. On one side above this cutting blade g, an actuating receiver h which is tensioned so that its tip protrudes to the opposite side is pivoted, and on the other side above the cutting blade g, the tip of the actuating receiver h is attached. A holder j having a tape holding surface i is provided at a corresponding position.

Further, a tape supply body k is attached to the operation frame d, and the part corresponding to the cutting blade g is recessed in correspondence with the recess e of the device base b.

As a result, when the object to be bound is placed on the table b and the operation frame d is tilted during binding, the tape supply body k is recessed while rotating the operation receiver h, as shown in FIG. It enters into the entry part e and binds the tape b in cooperation with the actuating receiver h, and presses the tape a against the tape holding surface, and when the binding is completed, the tape a is cut by the cutting blade g. .

(Problem to be solved by the invention) However, in such a conventional binding machine, the operation frame d is used to wrap the tape around the object to be bound.
When the tape is tilted and moved, the tape becomes slack, so there is a problem that winding and binding cannot be performed with the tape sufficiently tightened.

The present invention was devised to solve this problem, and aims to provide a binding device in which the tape does not slacken when the binding arm is tilted.

(Means for solving the problem) In order to achieve this purpose, the bundling device of the present invention has the following features:
A guide roller is attached to the binding arm so that the non-adhesive side of the tape pulled out from the tape reel can slide into contact with it.
A sector gear is attached to the shaft that pivots the base of the binding arm to the base, a gear in which the sector gear can freely mesh is attached to the base, and the arm that swings in conjunction with the rotation of this gear is attached to the base or the binding arm. one end of the arm engages with the tape extending between the guide roller and the tape reel, and is displaced perpendicularly to the direction in which the tape extends when the gear rotates, thereby applying tension to the tape. It is said that

(Function) In this configuration, by placing the object to be bound toward the tape stretched between the crimping table and the object to be bound, the tape pulled out from the tape reel will move as the arm tilts. Since the tape is pulled perpendicular to the direction in which the tape is stretched over the guide roller, tapes with small curvature are easily pulled by a small amount of movement of the arm, applying tension to the tape and preventing it from being covered. It is possible to wrap and bind objects.

(Example) An example of the present invention will be described below with reference to the drawings.

The distal end 4b of the binding arm 4 is opposed to the end of the base 1, and the distal end 4b has a first crimp rod 17 and a second crimp rod that are retractable and retractable, and are biased by a spring toward the projecting side. A crimp rod 18 is provided, and the crimp rods 17 and 18
A tape cutting blade 19 is fixed to the binding arm 4 in between. Furthermore, a cam surface 20 is formed on the tip portion 4b, and a tape push rod 21 and a tape escape rod 22 are attached near the cam surface 20. In the figure,
4c is a handle for raising and lowering the binding arm 4.

A crimping table 23 is integrally provided on the base 1 with a pair of left and right brackets 24 corresponding to the tip portions 4b of the binding arms 4, and a clamping device 25 is attached to the brackets 24.
A tape holder 26, which forms part of the tape holder 26, is rotatably mounted. The clamping rod 27, which constitutes the clamping device 25 together with the holder 26, is integrally formed between the distal ends of arms 28, 28 which are pivotally connected to the bracket 24, and is pressed toward the holder 26 by a spring (not shown). There is.

A plurality of holding grooves 26A, 26A, . It is configured to be held between rods 27. Note that the holder 26 is prevented from rotating in the counterclockwise direction in FIG. 1 by a claw plate (not shown). 29 in FIG. 1 is a guide plate for objects to be bound;
This prevents the objects A to be bound with tape from protruding toward the crimping table 23 side. A binding object mounting table 30 on which the objects to be bound A are placed is provided in close proximity to the crimping table 23, with one end fixed to the support frame 2.

Next, the operation of the binding device according to the present invention will be explained using FIG.

First, hold the end of the tape 8 between the holding rod 27 and the holder 26.
After the tape 8 is held in a tensioned state by being held between the tape 8 and the binding device A, the tape 8 is pushed in the direction of the solid line arrow, and the object A semi-wrapped with the tape 8 is placed on the object mounting table 3.
Place it on top of 0. When pressing this tape 8,
The tape reel 7 rotates around the reel support shaft 6 and lets out the tape 8 to a required length.

Furthermore, the binding arm 4 is tilted to wind the tape 8 around the object A, but at this time, the binding arm 4
According to the tilting movement, the sector gear 13 rotates counterclockwise in FIG. move in the opposite direction. Therefore, depending on the amount of movement of this arm 12,
Tape 8 caused by tilting movement of binding arm 4
The slack in the tape 8 is absorbed, and the tape 8 becomes taut and is wound around the object A.

When the first crimping rod 17 abuts against the crimping table 23, both ends of the wound tape 8 are crimped and pasted together. At this time or thereafter, the cam surface 20 causes the clamping rod 27 to move away from the holder 26 along the inclined surface of the cam surface 20.

Further, when the cam surface 20 contacts the holding rod 27 or after that, the pushing rod 21 engages with one of the holding grooves 26A via the tape 8. As the binding arm 4 tilts, the pushing rod 21 enters between the separated holding body 26 and the clamping rod 27, rotates the holding body 26 clockwise in FIG. Displace it to the receiving position. When the end of the second crimp rod 18 abuts against the holder 26, the push rod 21 stops descending, and the holder 26
6 also stops rotating.

After that, when the binding arm 4 is further tilted, the first crimp rod 17 is buried in the tip portion 4b, the clamping rod 27 is kept at a constant distance from the holding body 26, and the cutting blade 19 is held between the pushing rod 21 and the clamping rod 27. The tape relief rod 22 enters between the clamping rod 27 and the crimping table 23 and inserts the cut end of the tape 8 on the winding end side between the clamping rod 27 and the crimping table 23. Pull out.

Then, when pulling up the binding arm 4, the tape 8
The new end of the tape 8 is held between the holder 26 and the holding rod 27, and by raising the binding arm 4, the tape 8 is fed out from the tape reel 7, and the object to be bound A is
This will prepare the next tape binding. As this binding arm 4 is raised, the arm 12
approaches the binding arm 4 and returns to the original position while tensioning the tape 8.

By repeating the above operations, it is possible to repeatedly bind the objects A with tape.

In this way, the arm 12 of the tape tensioning means 10
In conjunction with the tilting movement of the binding arm 4, the sector gear 1
3. The binding arm 4 is rotated through the gear 14 in the opposite direction to the direction in which the binding arm 4 is tilted, that is, clockwise in the figure around the shaft 11, and is strung around the binding arm 4 by the guide roller 15 that moves along with this movement. The tension force is applied to the tape 8.

In the case of this invention, the degree of bending of the tape is small, that is, the curvature of the tape is small, and the tape 8 is pulled perpendicularly to the direction in which the tape extends, so that the arm moving in the opposite direction to the binding arm 4 Even if the amount of movement is small, the amount of slack in the tape can be corrected significantly, so the tape can be easily tightened.

Furthermore, although the tape tensioning means 10 is displaced by the tilting operation of the binding arm 4, this displacement is caused by the meshing of a pair of gears, that is, the sector gear 13 and the gear 14, so that the number of parts is reduced and the configuration is simplified. . Further, the amount of slack in the tape 8 caused by the size of the objects A to be bound can be adjusted by changing the length of the arm 12.

FIG. 2 shows a second embodiment of the binding device according to the present invention, and the binding device has a tape tensioning means 31 having a different configuration from the tape tensioning means 10 shown in the first embodiment. Then tie the tape reel 7 to the arm 4.
The same reference numerals in FIG. 2 as in FIG. 1 indicate the same components.

The tape tensioning means 31 has a shaft 35 fixed to a pair of right and left brackets 32 integrally formed in the middle part of the binding arm 4, and an arm 34 having guide rollers 33, 33', which serve as guide means, supported at both ends. of,
A chain 39 is wound between a sprocket 36 rotatably supported and attached to a shaft 35 and a sprocket 38 attached to a shaft 37 rotatably supported by the support frame 2, and a gear attached to the same shaft 37. 40 meshed with a sector gear 13 fixed to the binding arm 4. In the tape tensioning means 31, pulleys may be used in place of the sprockets 36 and 38, and a belt may be wound around both pulleys, and a fixing pin or the like may be used as the guide means. be.

A reel support frame 41 that supports the tape reel 7 is integrally provided at the middle part of the binding arm 4, and the tape 8 pulled out from the tape reel 7 is alternately applied to the guide roller 33' and the guide roller 33 in order as shown in the illustrated example. It comes into contact with the guide roller 16b and is guided to the tip of the binding arm 4.

In this tape tensioning means 31, the shaft 37 is rotated via the sector gear 13 and the gear 40 in conjunction with the tilting movement of the binding arm 4, and the rotational force of the shaft 37 is transmitted to the sprocket 38, the chain 39, and the sprocket 3.
6, the arm 34 is rotated clockwise in FIG. It is something. The amount of slack in the tape 8 caused by the size of the objects A to be bound can be adjusted by changing the rotation ratio of the sprockets 36 and 38 or the pulleys in their place, or by changing the interval between the guide rollers 33 and 33'. This is possible by doing the following.

Note that in this embodiment, the reel support frame 41
Of course, it may be directly attached to the base 1 as shown in FIG.

A feature of this second embodiment is that the tape reel 7 is attached to the binding arm 4 instead of the base 5 as in the first embodiment.

Therefore, the tape reel 7 is integrated with the binding arm 4, and as the binding arm 4 is tilted, the tape 8
Since the tape is not pulled out, the amount by which the tape is pulled out is smaller than that in the first embodiment, and the amount by which the tape is pulled out to correct tape slack can also be relatively reduced.

Therefore, the arm 34 can be rotatably attached to the bracket 32 fixed on the binding arm 4 via the shaft 35 without separating the arm 34 further from the binding arm 4.

As a result, according to the second embodiment, even if the bundling arm 4 is folded down when the bundling device is stored, the arm does not protrude as in the first embodiment, and the tape reel 7 stands vertically, but the tape Since it can be removed, the aircraft can be made more compact as a whole.

(Effects of the invention) As is clear from the above explanation, when the binding arm is tilted toward the base and the tape is wound around the object to be bound, the present invention is linked to the tilting movement of the binding arm. The curvature of the tape that is displaced is small due to the small degree of bending, and the arm moves perpendicularly to the direction of the tape extending through the guide roller, so the slack can be corrected with a small amount of movement of the arm. The tape can be easily tensioned to wrap and bind objects.
