Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a starting member for a binding machine using tape.

[Conventional technology]

The tape that has been wound into a reel is set behind the binding arm, the tape that is now fed out is passed from the binding arm to the tape holding device, and the object to be bound is inserted into the stretched tape, and the binding arm There is a binding machine that wraps the tape around objects to be bound by attaching and detaching the tape to a tape holding device.

By the way, these binding machines operate by using a motor or the like to drive a cam that operates the binding arm (many of them are set to have one rotation of the cam in one cycle). Place the objects to be bound on a mounting table for the objects to be bound, and use your hand to operate the appropriate starting member (in most cases, a downward motion is used) to issue a command to the starting switch. (Unexamined Japanese Patent Publication No. 57-77408,
JP-A-57-125107, etc.).

[The problem that the idea aims to solve]

On the other hand, a problem with this type of binding machine is that it may not be possible to tightly bind some items depending on the type of items to be bound. That is, structurally,
The tightness of the binding is determined by how close the items to be bound are placed to the tape holding device, so if this operation is insufficient, the binding will be loose. However, the objects to be bound generally have some elastic return force, so this is compensated for by this). However, in the conventional examples mentioned above, no special measures have been taken to compensate for this, and ordinary workers are often unable to perform this operation and are unable to tie the knots with sufficient tightness. was the reality.

[Means to solve the problem]

Therefore, this invention is a starting member for a tying machine which operates a starting switch of a drive motor by a constant pushing motion, and causes the tying arm to move toward and away from a tape holding device. , the starting member is located between the binding arm and the tape holding device and at a position very close to the tape holding device between a pedestal for placing objects to be bound and the tape holding device; At the same time, the starting switch is actuated by a pressing action by a constant displacement operation of the object to be bound placed on the pedestal towards the starting part.

[Effect]

As described above, before binding, the objects to be bound must always be displaced toward the tape holding device and pressed against the starting member provided close to this, so that the objects are bound at a position extremely close to the tape holding device. That will happen. On the other hand, if this operation is performed, it will also serve as the starting operation of the starting member.

〔Example〕

Hereinafter, embodiments of this invention will be described with reference to the drawings.

In the accompanying drawings, Fig. 1 is a plan view of the binding machine, Fig. 2 is a front view thereof, Fig. 3 is a partially sectional front view showing the relationship between the adhesive head and the tape holding device, and Fig. 4 is a diagram of the present invention. FIG. 5 is a partially sectional front view of the pedestal and the area around the tape holding device showing an embodiment, FIG. 5 is a partially sectional plan view of the same, and FIG. It is a diagram.

First, to explain the general configuration of this binding machine, the binding machine consists of a binding arm 3 and a tape 4 which are movable up and down around a horizontal support shaft 2 at opposing positions on the left and right sides with a pedestal 1 in between. A tape holding device 5 is arranged to hold one end of the tape.

The base of the tape 4 is wound around a drum 6 provided behind the binding arm 3, and one end is fed out and guided by the binding arm 3, extending to the tape holding device 5. . In this state,
When the object to be bound 7 is inserted onto the pedestal 1 from the outside of the tape 4 stretched between the binding arm 3 and the tape holding device 5 (as described later, the drum 6 can freely rotate at this time), The tape 4 becomes slack and is wound around the lower half of the object 7 to be bound.

Next, when the starting member 8 provided near the pedestal 1 is pushed down, it activates the starting switch 9.
and drives a motor (not shown) which is a drive source. Note that a gear 10 is fixed to the shaft driven by the motor, and this gear 10 meshes with another gear 11, so that it drives the other gear 11.

By the way, this gear 11 has two cams 12,
The cam 12 is shaped so as to come into contact with a pulley 14 fixed to the drum 6 during the first half of the binding cycle, thereby taking up the slack in the tape 4. It is absorbed by rotating it to the side. The other cam 13 is in constant contact with the roller 15 provided on the binding arm 3, and one rotation of this cam 13 (gear 11
The tip of the binding arm 3, that is, the tie, and the adhesive head 16 are configured to reciprocate once with respect to the tape holding device 5 in one rotation. Therefore, this motor receives the starting command from the starting switch 9.
Although not shown, the stop command is obtained from
The gear 11 is controlled by a micro switch that captures the movement of the operating cam 12 and controls the power of the motor.
Alternatively, it can be obtained by detecting one rotation of the cam 13.

On the other hand, when the adhesive head 16 moves back and forth to the tape holding device 5 in this way, the tape 4 binds and cuts the object 7.

That is, at the tip of the adhesive head 16, there is a pedestal 1.
A crimping body 17, a pressing body 18, a cutter 19, and a roller 20 are provided from the side, and a crimping table 21, a space 22, a fixed clamping body 23, and a movable clamping unit are also provided inside the tape holding device 5. A body 24 is equipped. By the way, the state of the tape 4 before binding is such that one end thereof is held between the fixed clamping body 23 and the movable clamping body 24, the base side is half wrapped around the lower half of the object to be bound 7 on the pedestal 1, and then , continues to the drum 6 through the roller 20,
At this time, when the starting member 8 is operated, the motor is driven as described above, and the binding arm 3 and therefore the adhesive head 16 are lowered to the tape holding device 5.

Then, first, the push-down body 18 pushes down the double-layered tape 4 into the space 22 to reduce the ring of the tape 4 wound around the object to be bound 7, and then the roller 20 moves. It comes into contact with the clamping body 24, moves the movable clamping body 24 backward from the fixed clamping body 23, and releases the hold on one end of the tape 4 held by both of them. While doing that, press the crimp body 17 this time.
descends onto the crimping table 21 and presses and adheres the two-layered tape 4 (glue sides both on the inside) between the two, while the cutter 19 also descends and presses the pressing body 18 and the roller. Upper tape 4 stretched between 20
will be cut off.

Next, the binding arm 3, i.e. the adhesive head 1
6 is raised by the action of the cam 13 and roller 15, the roller 20 also separates from the movable clamping body 24, and along with this, the movable clamping body 24 returns to its original position, and the end of the cut tape 4 is held again by the fixed clamping body. 23 and is held in a pre-binding state.

By the way, this invention is based on the above-mentioned starting member 8.
In this case, the tape holding device 5 is located between the receiving stand 1 and the tape holding device 5, instead of being installed near the pedestal 1 and activated by simply pushing it downward as in the conventional case. The starting switch 9 is installed in a position extremely close to the tape holding device 5, and the starting switch 9 is not activated until the starting switch 9
It was designed to work.

That is, the tape holding device 5 of the pedestal 1
One idea is to provide a horizontal support shaft 25 at a nearby position, and fit a plate-shaped starting member 8 that stands diagonally upward (on the side of the tape holding device 5) so that it can rotate freely around the support shaft 25. It will be done. Therefore, in order to start the binding machine, the starting member 8 must be moved toward the tape holding device 5 by a certain amount or more by the objects 7 and the like. It should be noted that an effecting body 26 is connected to the starting member 8 and extends to the starting switch 9, as well as a spring 27.
It is conceivable to use a stopper 28 so that the starting member 8 is always in a certain non-operating position, and to provide a suitable stopper 28 to achieve this positioning, and to place the starting member 8 against this. . Further, the object to be bound 7 and this starting member 8 come into contact, but in this case, a regular tape 4 is placed at the center of the starting member 8 so as not to prevent the tape 4 from wrapping around the object 7. A notch 29 with a width greater than the width is formed (see FIGS. 4 and 5). In addition, as another example, the front surface of the tape holding device 5 (the pedestal 1 side)
A similarly plate-shaped starting member 8 is attached to the support shaft 25 provided in the
It is also conceivable to have one fitted (see Figure 6).

As mentioned above, this idea is as follows.
The following effects can be expected.

First of all, since the objects to be bound 7 will be bound at a position extremely close to the tape holding device 5,
Tighten enough to form a tight bundle. This also means that there is less misalignment between the upper and lower tapes 4, which means that beautiful binding can be achieved, increasing the product value, and there are fewer mistakes in binding.

Next, place the object to be bound 7 on the pedestal 1 and move it to the side of the tape holding device 5 to a certain extent, then the starting member 8 will be pressed and the starting operation will be performed. This eliminates the need for the conventional starting operation, improving efficiency and saving labor.
In this regard, even in the conventional model, if a firm binding was to be performed, the objects 7 to be bound were inevitably brought to the side of the tape holding device 5 before binding, so in this invention, this operation is also used as a starting operation.
