Abstract

PURPOSE:To reduce noise and abrasion, to heighten long-range stability, economical efficiency and demand, and to reduce the whole apparatus to a compact size by providing one plate with an electrically-driven crank knife and driving motor united by a belt. CONSTITUTION:When a motor M is rotated, a pulley 4 is rotated by a driving belt 6 to start the movement of a crank rod 11, so that with the up-and-down motion of a crank pin 13, a knife shaft 17 is moved up and down between folding rollers R, R, thereby conducting an electrically-driven knife folding work. In this case, though the crank rod 11 is moved up at low speed due to rotation load, the crank rod is moved down at a speed higher than the drive side speed. Therefore, in the case where the drop speed exceeds the crank speed, and load such that load side rotates the drive side is produced, the crank motion of a main body (a) is caused indirectly by belt rotation, so that a transmission belt 6 is in the state of slipping to high speed rotation of the pulley 4 to avoid shock vibration or generation of noise. Accordingly, long-range stability can be ensured, and the apparatus on the whole can be reduced to compact size to improve space reduction.

Detailed Description of the Invention All crank-type paper folding knife devices in conventional paper folding machines are driven via a head gear to a rotating shaft equipped with an electric clutch and a brake mechanism that control the operation of an electric crank mechanism. This is a device that performs knife paper folding work by (2) vertical cranking motion of a paper folding knife by connecting a drive device to which a motor device is directly connected. Since the crank movement is performed by the action of a drive motor device directly connected to the blade gear, the crank movement is strongly lifted by the clutch carrier when the knife shaft moves upward, and vice versa when the knife shaft moves downward. In this case, the knife shaft performs a fast downward movement in a so-called free fall manner with no load applied, accompanied by the knife shaft's own weight descending blade, and the rotating shaft of the crank mechanism is accompanied by alternating changes in load as the knife shaft moves up and down, 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 phenomenon will occur in the meshing of mutual gears, and impact vibrations due to the gear tapping phenomenon will inevitably occur, resulting in intense gear tapping noise (3) every time the crank is moved. , due to severe wear and tear on the south-east motor,
This will have a large negative effect on the clutch, etc., and since the load must be accelerated in a short period of time when the clutch is connected, a very large surface pressure will be applied to the gear, and the crank mechanism will not be able to fold the knife paper. The more frequently the clutch gear is attached and detached due to high speeds, the more the above-mentioned knocking noise and wear and tear of the gears will become significant, and the motor, clutch, etc. will be more likely to be damaged, resulting in a lack of economic efficiency. In addition to lack of usability, the drive mechanism that connects the headgear has many drawbacks, such as the large installation space and large size. In order to cope with the above-mentioned load acceleration, it is possible to adopt a variable speed motor, but this would not only be uneconomical as the gear mechanism would be complicated and the motor cost would be high, but also the overall mechanism would be large. This led to an increase in the size of the paper folding machine as a whole, making it inappropriate and not being adopted.

In this case, the crank movement is performed under the lifting load of the rotating shaft (2) when the crank rod (1υ) is raised, but when the crank rod (1υ is lowered) from the top dead center to the bottom dead center. The rotation of the rotating shaft (2) is led in the alternating unbalanced load times I, 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. ; 11) The rise is a slow rise 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 exceeds the crank speed. , When a load occurs where the load side turns the drive side, the above-mentioned drawbacks occur in the conventional gear-coupled drive device, where a backlash phenomenon due to the southeastern backlash inevitably occurs. The present invention disposes the main body a and the drive (9) motor group + ftD separately from the single plate (1), and installs a transmission belt (6) to indirectly control the crank movement of the main body a. Since the rotation is performed by belt rotation, even if the free fall speed of the crank exceeds the crank speed and negative acceleration occurs such that the load side rotates the drive side, the load side boot IJ - (41 Even if the lower moving crank momentarily rotates faster than the rotation speed of the drive side pulley (5), the transmission belt (6)
Due to its adaptability, it slips when the load side boob IJ-(4) rotates at high speed, absorbs the load acceleration, and responds to the load, and only the load side becomes free. As a result, the drive side is driven higher than the drive side without any resistance.
Crank motion by belt installation is such that no matter what speed ratio the load side speed turns the drive side speed, and no matter how slow the 2-link frequency is, the belt will respond to the load acceleration and the load side will rotate. Slip times against the belt (1
0) Unlike a gear connection, there is no impact vibration or noise generated thereby, ensuring long-term stable performance with soundproofing.

Also, by installing a belt, the main body a and the motor device o
(1) can be placed and fixed separately from (1), so the entire knife device can be made into a compact unit, which is suitable for downsizing, and as a result, the installation space is saved. Because the drive and mechanism are extremely small, there is no noise at all in the drive and mechanism, and it is long-term usable and has excellent stability.It is convenient to provide a small unit type crank paper folding knife device, and the belt movement is very small. The mechanism allows the use of an ordinary small motor, which, together with the compactness of the unit, has great effects such as being very economical, practical, and highly demanded.
