Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a Q-liquor that shoots out an inverted U-shaped needle, particularly a 1-1 movement/river powered by Tanabata. It is something.

[Prior art]

Conventionally, a manual type tacker has been generally used. However, in this method, it takes effort to launch the 41, and there is a limit to how many needles can be launched], and the size of the needles is also limited by labor, making it difficult to work within the work. ′δ was limited. For this purpose, there are some that use air pressure and others that are powered by an electromagnetic solenoid that uses commercial power, but the former requires a separate air conditioner and 7-speed reducer, and the latter uses the attraction force of the electromagnetic solenoid. Because of the use of the power cord, it inevitably became large and heavy, and it was not possible to develop it into a rechargeable type that did not require a power cord.

[Purpose of the invention]

The present invention has been made in view of the above points, and its object is to provide an electric tacker that is small and easy to use.

[Disclosure of the invention]

Accordingly, the present invention provides a hammer for striking a needle, a spring that biases the hammer in the direction of striking the needle, a drive member that moves the hammer in the direction of the spring's bias in response to the rotation of Tanabata, and the above-mentioned. This electric tacker is characterized by an electric tacker consisting of an operation switch for controlling the Tanabata, which uses the power of the Tanabata to store the spring and release the hammer from the The hammer is driven by the force of the spring, and the needle is driven out.

Below-1, the present invention will be explained based on the rechargeable embodiment shown in the figure. In the figure, (1) is a housing, and at the bottom of this housing there is a stator.
A chest lug (11) is integrally formed in the center of the two parts. A spring (3) and a storage battery (8) are disposed before and after the cylinder (11) at the top of the housing IL+, respectively. The storage battery (8) is taken out from the housing fi+ and charged by a dedicated charging device (not shown). Kuri Sozu (+1)
A switch handle (7) is disposed on the lower curved portion of the switch, and operating the switch handle drives the actuator of the main switch Sochi S+, which is the operating switch. Gri2 5 (It is stored in the space between the lower part of Ill and the stage lma f5 engine t10i.)
f4t has a deceleration mechanism (40) attached to its tip and drives a worm (41) by deceleration output from this mechanism.

And the worm wheel (41) engages with the worm (41).
50) is a drive cam (5) and a switch as shown in Fig. 3.
It is installed on the drive shaft (51) together with the Sochi cam (6), and the drive cam (5) is
) and the switch cam (6) both rotate.

Now, the hesimmer (2) that emits the needle (9) is a series y'J-0 placed inside the curved part of the housing flll.
3), it is held vertically movable, and the hammer cam (1) is projected rearward, and the hammer cam (i2+11) is projected downward. Said splash (3)
is a cylindrical shape with a closed upper end that is screwed onto the upper end of the cylinder 031, and is housed in a 1" 1μ nozzle G! Adjustment No. 1
．． 3fJ)'s closed interior, J: The compression coil in contact with the surface is pressed against the cylinder (13) by rotating the adjustment knob (3) 1) that protrudes upward from the upper end of the housing il+. By adjusting the amount of screw engagement with the spring (3
The amount of compression that is the driving force for the hammer (2) in the hammer (2) can be adjusted.

The staple magazine is loaded with needles (9), and the presser foot spring (16) and needle holder (16) allow the needles (9) to be loaded into the staple magazine at one end where the feed opening (18j) is provided. 9
) is pressed and biased. Stable muff jin (10
) placed at the other end of the gold (19) is +1 Ujinjiro)
The lock handle (14j is stopped by locking on the end face, 5) disposed at the lower part of the rear end is a biasing spring for the 0-tsuku handle 041.

The switch cam (5) drives the Kamsui Sochi S2. As is clear from FIG. 2, this cam switch S2 has a normally closed contact and a normally open contact, and is inserted in series between the main switch S1 and the t-taper (4). Also, as is clear from the circuit diagram, the main switch Sochi S1 is formed by two switches, and the normally closed contact and normally open contact of the hum switch S2 are the common contacts of the two switches of the main switch Sl. 2 at the main switch S+.
One of the two normally closed contacts connects via the braking resistor R to the seventh contact (
4), the other one saves? The two normally open contacts are connected to the pond (8) in reverse order.

Next, the operation will be explained. First, a sample operation of launching the needle (9) will be explained. As shown in FIG. Since the moving cam (5) moves the hammer (2) upward by engagement with the hammer cam (5), the spring 13+ is compressed and stored. Press the hammer until the hammer head is above the stay
2) moves to the point where the needle (9) in the stapler mackerel (lOI) moves to the ejection opening (18) by the spring force of the presser spring (+5), the drive cam (5)
Since the engagement with the hash mark cam (21) is disengaged, the hammer (2) is rapidly driven downward by the return force of the spring (3), and as a result, the hash mark cam (21) is disengaged. The needle (9) is ejected through the ejection port 08).

By the way, if the needle (9) is driven out by the above operation, the heptad (4) will be the switch handle (7).
If it is rotated continuously during the period of operation, the following problems will occur, making it practically useless.

That is, in the illustrated example, since the drive cam (6) has two engaging parts with the hash mark cam (21), the needle (9) is ejected every half rotation of the drive cam (5). However, after striking one needle (9), if you do not move the tacker immediately or cut the Meishisui Sochi S1, the next needle (9) will be struck on top of the finished needle (91). Therefore, even if the rotation of the drive cam Ir+l is made at a very slow speed, the user will have to recycle after one shot is completed until the drive cam (5) pushes up the hammer (2) for the next shot. or remove your finger from the Sui-Sochi handle (7) and press the main switch S.
Even if we were to provide a time margin for the t-break to break 1, the number of needles (9) that can be driven in a certain amount of time would be extremely slow, making it impractical for practical use, and adjusting the timing itself would be inconvenient. Furthermore, even if the user were able to turn off the main switch Sochi S1 at the right time, the seventh gear (4), drive cam (5), etc. have inertia, making it difficult to stop suddenly. In some cases, there is a risk that the needle (9) may be repeatedly struck.

In order to eliminate such problems, as described above, the cam switch S2 driven by the switch cam (6), the main switch S1 constituted by a double switch, and the braking resistor R are used. The operation of these members will be explained based on FIG. FIG. 5 (1) shows the unused state, and shows the main switch S1 and the cam switch S.
2 is in a state where Tanabata is connected to the braking resistor R. Next, when the main switch Sl is switched by operating the Sui-Sochihandor (7), the t-tater (4) and the storage battery (8) are switched to the main switch S as shown in Fig. 5 (11).
In order to connect through one normally open contact of S1 and the normally closed contact of cam switch S2, the temperature switch (4) begins to rotate, causing both the drive cam (6) and the switch cam (6) to rotate.
When the hammer (2) is pushed up by the engagement between the drive cam (6) and the hammer cam (21) and the hammer (2) is released from the drive cam (5), the needle (9) is ejected as described above. It will be done. When the firing is completed, the switch cam ([)) presses the actuator of the cam switch S2 and switches it to the normally open contact side, as shown in Figure 5 (011). ) is turned off from the storage room (8) even though the main switch Sochi S1 is not turned off due to the switch Huff Dollar (7) being operated.
1V and is connected to the braking resistor R at the same time. Therefore t
- The motor (4) is one that is braked and comes to a sudden stop.

After this, when you release your finger from the switch handle (7) and return the main switch Sl, the t-tater (8) is connected to the storage battery (8) through the normally open contact of the cam switch S2, as shown in Figure 5 (Vl). After being connected, the switch cam (4) resumes rotation, but the switch cam (5) stops before the drive cam (5) reaches the engagement point with the hammer cam (21) of the hammer (2).
) returns the cam switch S2, so the fifth
As shown in FIG. 5(V), the f-taper (4) is again switched to the connection with the braking resistor R and suddenly stops, returning to the initial state shown in FIG. 5(1).

In other words, operate the switch hashidor (7) once.
If it is a case, the needle (9) will be launched only once regardless of whether it is open or not during operation, and it will return to its initial state when you release your finger from the switch handle (7). It does not cause the trouble of hitting the needle (9) twice in the same place, and moreover, it
4) Requires rotation 11. You don't have to slow it down any more than you need to to get the desired effect.'' Secondly, when stopping Tanabata (4), the brakes are applied to stop it, so it is not affected by inertia, regardless of the skill level of the user. It is a tacker that can perform reliable work, and is especially suitable for difficult work.As mentioned above, this tacker requires no adjustment. Since the compression ball of the spring (3) can be changed by turning the needle, the force with which the needle (9) is driven can be adjusted depending on the person to whom the needle (9) is to be dipped. It is.

In addition, in the illustrated example of glue/river, the hammer +21 and the blade 3) are attached to the front end of the housing (1), and the housing fl+
A reservoir (8) is provided at the rear end, and a chest (8) is provided between them. ), etc.,
It has a good overall bounce and does not tilt when you hold the Kuri Sora (11), making it easy to handle.
1) It is easy to push the bottom of the pruner toward the surface, and the needle (9
) It is easy for the user to withstand the recoil when driving, and 3) it is rechargeable and cordless.

In this embodiment, braking when stopping the t-tater (4) is performed by disconnecting the Tanabata circuit using the Musui Richi S2 and connecting it to the Yail dynamic resistance R. (4) and drive cam'(
It is also possible to mechanically separate the drive member shown in 5) and apply mechanical braking to the drive member or the drive member (4).

〔Effect of the invention〕

As mentioned above, the present invention utilizes the power of Tanabata to move the hammer with the drive member, and the spring pressure stored in the spring during this movement drives the hammer released from the drive member to move the needle. Since the power is Tanabata, it can be made more efficient, smaller and lighter than those using air pressure or electromagnetic solenoids. The needle is driven out by the upper and lower rotations, but the power is stored in a spring and the spring pressure is used to drive out the needle via a hammer, so it is not as powerful as the printer's ability. When launching and releasing a large needle, r't': U speed 1
It is a device that can be used as a ``facility'', and it is easy to make it cordless as a fully equipped fa-type.
