Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for binding objects to be bound with tape in conjunction with vertical movement of a binding arm.

(Prior art) Fig. 8 shows a conventional binding device of this type (see Utility Model Application No. 49-7030). , a cutting blade which is provided by pivoting the end of an operation frame d having a handle c, and has a blade edge f facing upward in the center part of the bottom surface of a recess e formed on the side of the receiving part a of the device base b. g, and on one side above the cutting blade g, there is pivotably mounted an actuating receiver h which is tensioned so that its tip extends to the opposite side, and on the other side above the actuating receiver h. A holder j having a tape holding surface i is provided at a position corresponding to the part, and a tape holder j is provided in the operation frame d to correspond to the recessed part e of the device base b, and a part corresponding to the cutting blade g is recessed. When the supply body k is attached and the object to be bound is placed on the receiving part a with the tape l applied to it during binding, when the operation frame d is tilted, as shown in FIG. The tape supply body k enters the recess e while rotating the actuating receiver h, binds the tape l in cooperation with the actuating receiver h, and presses the tape l against the tape holding surface i, When the binding is completed, the tape 1 is cut by the cutting blade 7.

(Problems to be Solved by the Invention) In the conventional example as described above, as shown in FIG. However, during the instant after the tape supply body k leaves the tape holding surface i until the actuating receiver h comes into contact with the tape holding surface i, neither the actuating receiver h nor the tape supply body k makes contact with the tape l. Therefore, the tape l is held on the tape holding surface i solely by its adhesive force, but dust and moisture from the objects to be bound often adhere to the tape l. This may cause the tape to lose its adhesive strength and come off the tape holding surface i.
There was a problem.

In addition, since the tape l may come off in this way, it is not possible to provide a rewinding mechanism that applies rewinding force to the tape reel.
Inability to apply sufficient tension to the tape,
There was this inconvenience.

The present invention was made to solve this problem, and an object of the present invention is to provide a binding device that can securely hold the end of a new tape after winding and binding.

(Means for solving the problem) The present invention pivots the base of the binding arm to one end of the base, and makes the first and second tape pressing members retractable and projectable from the tip of the binding arm. A cutting blade is provided between the first and second tape pressing members, and a cutting blade is provided at the other end of the base in cooperation with the first and second tape pressing members, respectively. A clamping rod is provided between the first and second pressure-receiving members to clamp the end of the tape in cooperation with the first pressure-receiving member. An operating member is provided between the binding arm and the clamping rod to separate the clamping rod from the first pressure-receiving member when cutting the tape, and the tip of the binding arm is provided with an operating member that separates the clamping rod from the first pressure-receiving member. A tape pushing rod is provided that enters between the first pressure receiving member and a clamping rod that is in contact with the first pressure receiving member and is spaced from the first pressure receiving member, and the first tape pressing member is connected to the first pressure receiving member. After the tape pushing rod contacts the first pressure receiving member through the tape, and after the tape pushing rod separates from the first pressure receiving member, the first tape pressing member The first pressure receiving member is separated from the first pressure receiving member.

(Function) When the objects to be bound are placed against the tape on the object mounting table and the binding arm 3 is tilted, the tape will be wound around the objects to be bound, and this winding will be completed. When the tape is finished, the first tape pressing member contacts the first pressure receiving member, and the second tape pressing member contacts the second pressure receiving member, thereby sandwiching the tape.
When the binding arm further tilts, the operating member separates the clamping rod from the first pressure-receiving member, and the tape pushing rod comes into contact with the first pressure-receiving member. When the binding arm further tilts, the cutting blade moves to the first pressure-receiving member. It enters between the pressure receiving member and the clamping rod and cuts the tape stretched between them. After cutting the tape, when the binding arm starts to stand up, the operating member and the tape pressing rod start to move upward, but in this state, the tape pressing rod still remains in contact with the first pressure receiving member. When the binding arm further stands up, the tape pressing rod moves away from the first pressure receiving member, and the clamping rod comes into contact with the first pressure receiving member to clamp the tape.
At this point, the first tape pressing member remains in contact with the first pressure receiving member, and when the binding arm further rises from this point, the first tape pressing member separates from the first pressure receiving member.

A plurality (six in this case) of tape holding grooves 14A ₁ , 14A ₂ . . . having an arc-shaped cross section are formed at equal intervals. 14B is a rubber ring for reinforcing the grip.

The clamping rod 1 is attached to the tip 3A of the binding arm 3.
An operating member 19 for separating the pressure receiving member 6 from the first pressure receiving member 14 is integrally provided. Operation member 19
Here, the clamping rod 16 is connected to the first pressure receiving member 14.
It includes an inclined cam surface 19A that allows the clamping rod 16 to be displaced to a fixed position in a direction away from the cam surface 19A, and a vertical cam surface 19B that allows the clamping rod 16 to be maintained at a fixed position.

As shown in FIGS. 3 and 4, the distal end portion 3A of the binding arm 3 is provided with a clamping rod 16 that is in contact with the first pressure receiving member 14 via a tape and is spaced apart from the first pressure receiving member 14. A tape pushing rod 20 that enters between the first pressure receiving member 14 and the first pressure receiving member 14 is provided. Here, the tape pushing rods 20 are arms 20A, 20A.
and a shaft portion 20B that is integrally provided between the tips of the arms 20A, 20A.
The bases of 0A and 20A are pivotally supported by the distal end 3A of the binding arm 3 via a shaft 21, and are biased clockwise by a spring 22 via a pin 22A.

A tape relief rod 24 is provided between the cutting blade 15 and the inner tape pressing member 9 and is fixed to the binding arm 3. Reference numeral 24 in the figure is a protrusion prevention plate for objects to be bound, which extends upward and outward from both sides of the right end of the second pressure receiving member 13 in FIG. The role of preventing the protrusion of 26 is different. The bottom of the opening 25A formed in the extrusion prevention plate 25 may be approximately at the same height as the second pressure receiving member 13.

In the above configuration device, as shown in FIG.
The end portion 6A of the tape 6 fed out from the tape feeding device 5 is placed in one of the plurality of tape holding grooves 14A ₁ , 14A ₂ .
A ₁ ) and the clamping rod 16, and push the bound object 26 in the direction F from between the tip 3A of the binding arm 3 and the first pressure receiving member 14, and place it on the bound object mounting table 2. (state A in Fig. 1).

Next, the binding arm 3 is lowered to wrap the tape 6 around the object to be bound 26. At this time, tied arm 3
The excess tape that has become slack due to the lowering of the tape is rewound to the tape feeding device 5 by the rewinding mechanism 8. When the binding arm 3 is lowered to the position shown in FIG. 9 collides with the second pressure-receiving member 13 via the tape 6, and the adhesive surfaces of both winding ends of the tape 6 wound around the object 26 are stuck together. At this time or thereafter, the operating member 19
When the inclined cam surface 19A of the cam surface 19A contacts the clamping rod 16, and then the binding arm 3 descends, the second tape pressing member 9 with the shortened spring 11 is kept in contact with the second pressure receiving member 13, and the clamping rod 16 is held. The rod 16 is separated from the first pressure receiving member 14 along the cam surface 19A as the binding arm 3 descends.

Thereafter, as shown in FIG.
A ₁ , 14A ₂ ... (this will be referred to as 14A ₂ ) is engaged with one of them through the tape 6, and then the tape pushing rod 20 is lowered as the binding arm 3 is lowered,
It enters between the clamping rod 16 which is spaced apart from the first pressure receiving member 14 and the first pressure receiving member 14 . At this time, the first pressure-receiving member 14 rotates approximately 60 degrees clockwise under the downward force of the tape pushing rod 20, and the tape holding groove _14A2 is displaced to a position where it can receive the holding rod 16.

As shown in FIG. 6, when the upper end of the first pressing member 10 collides with the stopper portion 3C fixed to the binding arm 3, the binding arm 3 stops descending and the tape pushing rod 20 stops descending. , first pressure receiving member 14
The rotation also stops. Then, while the binding arm 3 is lowered from the position shown in FIG. 5 to the position shown in FIG.
is shortened, and the first tape pressing member 10 is kept in abutment with the first pressure receiving member 14, and the clamping rod 16
is maintained at a constant distance from the first pressure receiving member 14.

Then, as the binding arm 3 descends, the cutting blade 15 enters between the tape pushing rod 20 and the clamping rod 16 to cut the tape 6. In addition, tape escape rod 2
4 enters between the clamping rod 16 and the second pressure-receiving member 13, and pulls out the cut end of the winding end side of the tape 6 together with the end 6A between the clamping rod 16 and the second pressure-receiving member 13. Therefore, the clamping rod 16 and the first pressure receiving member 14
The cut end of the tape 6 on the winding end side is no longer caught between the tape 6 and the tape 6.

After that, when the binding arm 3 is raised, the cutting blade 15
Then, the tape release rod 24 and tape pusher rod 20 return upward. In this case, since the reverse rotation of the first pressure receiving member 14 is regulated, the tape pushing rod 20 is inserted into the outer periphery of the first pressure receiving member 14 while holding the tape 6 between it and the first pressure receiving member 14. rise along. Note that when the binding arm 3 is raised, the tape 6 is pulled out from the tape feeding device 5 as the binding arm 3 is raised, but when the tape 6 is drawn out from the device 5, a relatively large peeling resistance is generated in the tape 6. , Therefore, the cut end of the tape 6, that is, the tape 6
A tensile force is generated at the new end 6A'. However, in the apparatus of the present invention, the force of the spring 12 holds the tape 6 until the clamping rod 16 engages with the tape holding groove _14A2 of the first pressure receiving member 14 and clamps the new end of the tape 6. is the first pressure receiving member 14
Since the tape 6 is strongly clamped between the tape 6 and the presser roller 10B of the first pressing member 10, the risk of the tape 6 coming off is reduced.

Further, tape slippage due to peeling resistance of the tape 6 is likely to occur particularly at the beginning of the rise of the binding arm 3, but in the device of the present invention, at the beginning of the rise of the binding arm 3, that is, when the binding arm 3 is in the sixth position. 5th from the position shown in the figure
Until the position shown in the figure is reached, the tape 6 is moved between the first pressure receiving member 14 and the first pressing member 10 and between the first pressure receiving member 1 by the force of the springs 12 and 11.
4 and the shaft portion 20B of the tape pushing rod 20, and a particularly large clamping force is obtained, there is no risk of the tape 6 coming off.

By repeating the above-described raising and lowering operations of the binding arms, the work of binding the objects to be bound 26 can be performed repeatedly.

Although one embodiment has been described above, the present invention is not limited to the above embodiment, and includes, for example, the following modifications.

As the second tape pressing member 9, as shown in FIGS.
It may be configured so that it is pressed against the wall surface of No. 3.
Here, the tip of the pressing rod 9C is equipped with a roller 9D.
is installed. In the case of this example, the pressing rod 9C of the second tape pressing member 9 plays the role of crimping the winding end of the tape 6, and also serves as a tape release rod. The relief rod 24 can be omitted. Moreover, in the case of this example, since the roller 9D at the tip of the pressing rod 9C moves along the wall surface of the second pressure receiving member 13 while pressing the winding end of the tape 6, the vicinity of the tip of the tape winding end This means that the tape can be crimped over a wide area, increasing the strength of the tape binding.

In this example, the wall surface of the second pressure receiving member is an inclined surface, but it may be a vertical surface.
Further, the movable rod 9A and the pressing rod 9B may be integrated and formed of a flexible member. Furthermore, the second pressing member 9 and the second pressure receiving member 13 may be overlapped one after the other with a gap between them. In FIG. 7, the same reference numerals as in FIGS. 1 to 6 indicate the same components as in the above embodiment.

Instead of the pressing roller 10B, a pressing rod may be fixed to the tip of the first tape pressing member 10.

The first pressure-receiving member 14 may be of a substantially circular cross section without the tape holding groove, or may be fixed to the base 1 in a non-rotatable manner.

The clamping rod 16 may be one that is provided between the second and first pressure receiving members 13 and 14 and configured to clamp the end 6A of the tape 6 in cooperation with the first pressure receiving member 14. For example, another structure may be adopted, for example, by providing two arms facing the first pressure receiving member 14 so as to be horizontally displaceable, the arms being biased by a spring toward the first pressure receiving member 14, and a clamping rod between the two arms. 16 are integrally formed, and the clamping rod 1
6. It may be positioned between the first and second pressure receiving members 14 and 13.

The operating member 19 may have any other structure as long as it can separate the clamping rod 16 from the first pressure receiving member 14 as the binding arm 3 moves downward. For example, the arm 1 integrated with the clamping rod 16
7 and 17 to indirectly separate the clamping rod 16 from the first pressure receiving member 14.

The tape guide 7 may be fixed to the binding arm 3 or supported by a support provided vertically on the base 1.

The binding arm may be moved up and down electrically.

The tape feeding device 5 may be supported by a binding arm.

When placing the object to be bound 2 on the outside of the tip of the base, reverse the arrangement of the inside and outside of the first and second tape pressing members, first and second pressure receiving members, etc. as described above, The cutting blade, tape release rod, etc. may be appropriately arranged.

(Effects of the Invention) As explained above, in the present invention, after the first tape pressing member contacts the first pressure receiving member via the tape, the tape pushing rod contacts the first pressure receiving member via the tape. and after the tape pushing rod separates from the first pressure receiving member and before the first tape pressing member separates from the first pressure receiving member, the clamping rod is brought into contact with the first pressure receiving member. Therefore, at the beginning of the upward movement of the binding arm until the binding arm is moved upward and the clamping rod is pressed against the first pressure-receiving member, the tape is held by the first tape pressing member and the tape pushing rod. Since the end of the new tape is securely clamped after being wound and tied, it is clamped by the first tape pressing member until the clamping rod comes into contact with the first pressure receiving member. It turns out.

Furthermore, when the tape pushing rod is in contact with the first pressure receiving member, the tape is supported by the first tape pressing member, so even if the tape tension is large, the tape pushing rod is not pressed against the first pressure receiving member. Therefore, the tape pushing rod is fixed by firmly contacting the first pressure receiving member, so that the tape is pushed down greatly by the cutting blade when cutting. As a result, the tape can be cut reliably.

Furthermore, since the tape pushing rod does not tilt as described above, the tape pushing rod does not interfere with the cutting blade during cutting.
