Abstract

PURPOSE:To improve the operability of a small-sized unit by providing a belt driving unit-type folding knife device, the knife position of which can be controlled to move up and down by a control screw mechanism, with the knife device body not moved. CONSTITUTION:In case of controlling the vertical position of a knife according to the crank motion, a fixing nut 25 is loosened, and a handle grip 23 is turned to rotate an adjust screw 24 so that a knife shaft 18 threaded on a cap screw portion 14 is, with the movement of the screw 24, adapted to move up and down with expansion and contraction of an elastic member 20 round a core bar 21, so that the height of the knife position can be controlled simply, quickly and accurately. Then, the fixing nut is fastened to be fixed. In this arrangement, only the knife shaft 18 can be directly fine-controlled quickly and correctly by simply turning a screw, not moving the main body (a) and regardless of the crank up- -and-down motion of the knife.

Description

[Detailed Description of the Invention] Since the vertical adjustment of the knife position cannot be performed by adjusting only the knife shaft, but only by adjusting the entire knife device itself (2), the head carrier is directly connected. Since the drive motor device related to this is also moved up and down at the same time, it is impossible to fix the knife device main body and the drive device to a single plate, and as a result, there is a defect that the entire device cannot be integrated into a unit. In addition, the above-mentioned conventional device connects a drive device, in which a drive motor device is directly connected via a head gear, to a rotating shaft equipped with an electric clutch and brake mechanism that controls the operation of an electric crank mechanism. Since this is a device that performs knife paper folding work by cranking the knife up and down, the cranking motion of the knife is performed by the action of an electric clutch, a brake mechanism, and a drive motor device directly connected to the head gear. The movement is such that when the knife shaft rises, a strong lifting load is applied by the clutch gear, and on the other hand, in the case of "'F"@ of the knife shaft, the load is applied along with the lower blade of the knife shaft. (3) A free-falling downward movement occurs, and the rotating shaft of the crank mechanism is accompanied by alternating changes in load due to the vertical movement of the knife shaft, and
During the downward movement process of the crank from top dead center to bottom dead center, if the free fall speed of the downward movement exceeds the crank speed, a load will occur in which the load side turns the drive side, and the result is , a backlash movement phenomenon occurs in the meshing of mutual gears9, and impact vibrations due to the knocking phenomenon of both sides inevitably occur, and the noise of the gears hitting is intense every time the crank moves. This will lead to severe wear and tear, which will have a major negative effect on the motor, clutch, etc. Also, when the clutch is connected, the load must be accelerated in a short period of time, so the gear will be subject to a large amount of surface pressure. Due to the high speed of knife paper folding using a crank mechanism,
The more frequently the clutch gear is attached and detached, the more the above-mentioned knocking noise of the gears, the wear and tear of the gears, and the more easily the motor, clutch, etc. are damaged, which makes it less economical. Therefore, in addition to lacking soundproofing properties and long-term usability, the drive mechanism connected to the headgear has many drawbacks, such as requiring a large installation space and becoming large. At the very least, it is conceivable to adopt a variable speed motor to cope with the above load acceleration, but this is not only uneconomical as the gear mechanism is complicated and the motor cost is high, but also the overall mechanism is large. This led to an increase in the size of the paper folding machine as a whole, making it inappropriate and not being adopted.

The present invention reliably eliminates the above-mentioned drawbacks of the conventional art. The main body of the device and the drive motor mechanism are arranged separately on a single plate, realizing a compact unit of the entire device, and the conventional gear connection is not used for the motor connection.(5) By creating a transmission belt construction mechanism that can handle load acceleration, any ordinary small motor can be used.In addition, by being able to handle load acceleration, noise and wear are reduced compared to conventional gears. These shortcomings have been completely eliminated, and a crank drive mechanism with high performance can be installed in a small unit that is long-lasting, economical, and highly demanded.We have created a unit-type crank paper folding knife device that is soundproof and long-lasting. In addition, the transmission belt installation design allows the device main body and the drive mechanism to be separated and fixed without having to lift and lower the entire knife device main body including the drive mechanism,
The purpose of this invention is to provide a rank-type knife device that is very convenient in handling the knife adjustment, in which the knife position can be adjusted by operating only the adjustment screw mechanism. The knife position can be adjusted up and down by the mechanism while the knife device main body remains stationary, and the knife shaft is electrically operated (6) An electric crank type knife device main body that moves up and down by a crank mechanism, and a drive motor device that drives the crank mechanism. are not directly connected, but are separated from each other, and a transmission belt is installed over a portion of the mutually opposing pulleys, so that they are arranged and fixed as a unit.

To explain the embodiment of the present invention with reference to the drawings, (1) is a single rectangular plate, and a suitable adjustment screw mechanism is provided at the lower part of the single plate (1) to adjust the knife position up and down. An electric crank type knife device main body a in which an adjustable paper folding knife mechanism moves up and down by an electric crank mechanism;
A drive motor device O for driving the main body a is installed in the upper part of the upper part of the main body a, and is separated from the drive motor device O for driving the main body a.

An example of the structure of the electric crank type knife device main body a is as follows.

That is, (7) is the m-clutch and brake mechanism, and 18) is a case equipped with the brake machine #t71 so as to protrude into the entire interior of the rotating shaft (2).
gi] surface is provided with a box interior (il-a window hole (1) suitable for monitoring and l11 operation), and a crank mechanism is provided inside. An example of this mechanism is an eccentric plate 1 on the rotating shaft (2).
11 is fixed to it, one end of the crank rod 1υ is fastened with a screw (1 force), and the other end is fitted with a crank pin (1 screw).

A coil spring or other suitable elastic member clQ is pushed into the deep bottom of the inside of the cylinder, and an idle core frame 121) having a length that reaches the threaded part (14) that slides inside the cylinder is loosely fitted thereon. Attach the crank pin (13 to the lower part of the core frame &I) by vertically drilling a long hole @ in a corresponding range in the wall of the knife shaft 11 corresponding to the bottle (13), and screw it through the long hole (A). , knife axis i, 1g through the through hole + of the casing (8)
The shaft (for the threaded part (14) above I81, the lower surface is in contact with the core frame I2+) and the upper part is exposed to the outside, and is screwed into the threaded part 114). Screw the adjustment screw [with] to which the bundle knob 2 is attached until it touches the play core frame 121), and then tighten the loosened IE fixing nut (to) with a knife against the threaded part of the screw (■). It is constructed by screwing toward the upper edge of the shaft.

Note that the configuration of the main body a is not limited to that shown in the drawings, and various designs of the knife shaft mechanism, adjustment screw mechanism, etc. may be adopted.

Then, the rotating shaft (2) of the main body a is passed through the plate (9) and the plate (1), and the pulley (4) is attached to the protruding shaft portion.
) is attached and fixed to the plate (1), and an ordinary drive motor M is arranged and fixed to a nearby upper part of the main body a with its rotating shaft (3) protruding outside the plate,
A pulley (4) of the main body a is attached to the protruding shaft portion of the rotating shaft (3).
Attach pulleys (5) that face each other vertically, and install a suitable soft power transmission belt (6) made of rubber, resin, etc. between the pulleys (4) and (5) to connect both main bodies a and the motor. A single plate (
In contrast to 1), the unit is arranged in a belt-driven manner.

In the drawing, the main body a and the motor device are arranged vertically relative to the single plate (1), but if the plate (1) is used horizontally, the arrangement becomes horizontally horizontal. In the figure, RR is a paper folding roller.

Since the present invention has the above-mentioned configuration, when the Goo IJ-(5) is rotated by the rotation of the motor, the Goo IJ-F4) of the main body a is transmitted and rotated by the drive belt (10) (6). ) rotates, and along with the rotation of the eccentric plate, a crank movement of 1υ is performed on the crank rod (1υ), and the crank pin (
Along with the vertical movement of the electric knife, the knife shaft (I8) is moved up and down between the paper folding rollers RR, and the electric knife paper folding action is performed.

In this case, the crank movement is performed under the lifting load of the rotating shaft (2) when the crank rod tll) is raised, but when the crank rod +11) is lowered, it is from the top dead center to the bottom dead center. The rotation of the rotating shaft (2) is led by alternating unbalanced load rotations in which the free fall speed exceeds the crank drive speed due to the falling action of dead weight during the downward movement process reaching the point. Therefore, the upward movement of the crank rod 11) is a slow upward movement due to rotational load, whereas the downward movement changes to a high-speed downward movement that exceeds the drive side speed, so the free fall speed is the crank speed. When a load occurs that causes the load side to turn the drive side, the conventional head (1)
1) In a gear-connected drive device, a backlash phenomenon of the gears inevitably occurs, and the above-mentioned drawbacks are overcome, but the present invention provides a combination of the main body a and the drive motor device! : is arranged separately from the single plate (1), and by installing the transmission belt (6), the crank movement of the main body a is indirectly performed by the rotation of the belt, so that the free fall of the crank does not occur. Even if load acceleration occurs such that the speed exceeds the crank speed and the load side turns the drive side, that is, the pulley (4) on the load side instantly turns the drive side boot I with the downward movement crank.
Even if a situation occurs where the transmission belt (6) rotates faster than the rotational speed of the load-side boot (IJ-tfi), due to its adaptability, the transmission belt (6) slips against the high-speed rotation of the load-side boot IJ-(4). The load acceleration is absorbed and corresponds to the load, and as a result, only the load side automatically drives faster than the drive side without resistance.As a result, the crank movement due to the belt installation is such that the speed on the load side becomes the speed on the drive side. No matter what the speed ratio is when turning the belt, and no matter how violent the cranking frequency is, the belt will respond to the load acceleration, and the load side will slip and rotate with respect to the belt, and unlike gear connections, there will be no impact. Vibration and the noise generated by it are completely eliminated, and long-term stable performance is guaranteed with soundproofing.

And the vertical position AMI of the knife due to the crank movement
n6 is performed as follows. That is, crank bin (
The vertical movement of the crank by one step is caused by the elongated hole (〃
Due to the movement, the play core frame 111 loosely fitted in the cylinder of the shaft (181 and supported by the bottle (1))
slides up and down inside the cylinder under the elasticity of the elastic member 121), and its upward movement pushes up the upper adjusting screw (■) that is in contact with the screw (@). The attached knife shaft t181 should be screwed together with the screw (24).
The paper folding knife αη moves upward, and conversely, the lower surface of the core frame 0 presses the elastic member (13), so the pressed spring pressure causes the entire shaft frame to move downward. is lowered at the same time, and the shaft and shaft are moved up and down by the crank to perform the knife paper folding work.To adjust the knife position, loosen the fixing nut (2), turn the handle knob (2), and tighten the I14 node screw.

As the screw (to) rotates, the knife axis and the blade will move up and down with the elastic member (4) around the core frame (Jl), and the height of the knife position will change. is adjusted simply, quickly and accurately, and is then secured by tightening the fixing nut.

As a result, the knife axis (lip) can be directly, simply, quickly, and accurately fine-adjusted by simply turning the screw without moving the main body a at all and regardless of the vertical movement of the knife crank. can.

As described above, the gist of the present invention, which is to unitize the main body a and the motor unit mb in a separate arrangement with respect to a part of the plate (1), is particularly effective when the main body a remains immobile and the knife ll],
+81, it is the most effective mechanism with 14 joints (14), and it is possible to design a belt installation for the main body a (!: the drive mechanism), and for that reason, the knife device can be made into a small, vertical body. Since unitization is realized, it is suitable for miniaturization, and as a result, the installation space is extremely small, so the drive mechanism has no noise at all, has long-term usability, and has excellent stability. Not only is it convenient to provide a compact unit-type crank paper folding knife device, but the belt drive mechanism allows the use of suitable small-sized motors, making it very economical when combined with the compact unit. Furthermore, since the knife can be adjusted while the main body a remains stationary, it is extremely convenient and convenient to handle, and has great effects such as greater practicality and demand.
