[Industrial applications]

 The present invention relates to a brake assist device for a paper box forming machine that bends a kind of paper piece to form the outer shape of a paper box, and in particular, reliably stops two transmission shafts on the transmission device of the paper box forming machine at the moment when the electric motor stops rotating. State, thereby reducing the occurrence of collision stress in parts and extending the service life of the entire transmission.

[Prior art]

 In a commonly used transmission mechanism of a paper box forming machine, two transmission shafts, a main shaft connected to an electric motor and a driven shaft at the other end, are attached to a frame. This uses a single shaft joint to connect both ends in advance by connecting them in series to transmit the rotational power of the shaft. However, in this type of shaft joint, multiple bolts are inserted into the screw holes of one shaft joint and connected in series, and the shaft joint at one end is the center of the other shaft joint. The screw holes on the shaft coupling are oblong tank-shaped holes in order to cancel out the slight deviation and to facilitate the insertion and coupling of the bolts. This allows a small amount of error in distance to easily adjust the bolt insertion position and eliminates the center error between the two transmission shafts. This allows the inserted bolt to slide within the oblong hole.

In addition, in the case of a shaft coupling that is tightened by a ball eccentric method to generate a transmission effect, or in the case of inserting an elastic material object into the shaft coupling to eliminate the central deviation of the two shaft couplings, this type of transmission is used. In the structure, when the motor stops rotating, the moment of inertia may cause the bolt inserted in the shaft coupling to cause a sliding phenomenon due to inertia in the oblong hole on the other shaft coupling. At this time, the transmission shafts at both ends cannot perform the braking operation synchronously, and the stresses that impact each other are generated. This not only creates the noise of collision of metal parts, but also forms wear of the transmission parts, and after long-term use, it shortens the operating life of the whole box forming machine transmission parts, and therefore the improvement is I was waiting.

 The brake assisting device of the paper box forming machine of the present invention is such that the stationary shaft sleeve is fitted on the outer peripheral portion of the shaft ring body of the shaft coupling that is in contact with the two transmission shafts, and when the electric motor stops rotating, The brake piece first puts the outer edge of the shaft ring body of the two shaft couplings together and sandwiches the two together to generate a braking action, which reliably stops when the transmission shafts at both ends stop rotating. The problem is to reduce the occurrence of impact stress in the transmission shaft parts connected at both ends of the shaft joint, thereby extending the service life of the paper box molding machine transmission parts.

[Action]

 The brake assist device of the paper box forming machine of the present invention is on the transmission device of the paper box forming machine that bends a piece of paper to form a paper box, and is installed on the outer edge of the shaft joint that is in contact with two transmission shafts on the frame. A detent shaft sleeve that generates expansion or closing contraction force is fitted, and a brake piece is attached to the inner edge of the detent shaft sleeve, and the drive unit at the upper end of the detention shaft sleeve serves as a fluid driver to send force. When they are fitted together, the brake pieces are condensed and placed on the outer edges of the axles of the two shaft couplings, thus, when the paper box forming machine is stopped and the electric motor is stopped, the two transmissions are stopped. The shaft does not generate a shock action due to the generation of a gap due to the braking action in which the outer ring edge of the shaft coupling is tightly bound by the brake pieces, and the shock stress phenomenon of the transmission parts does not occur. The service life of the molding machine transmission can be extended.

【Example】

 FIG. 1 is a diagram showing a three-dimensional structure of the present invention. The break assisting device of the paper box forming machine shown in the figure is on the transmission of the paper box forming machine that bends a piece of paper to form the appearance of a paper box, and is a shaft coupling that connects two transmission shafts on the machine frame. A captive shaft sleeve 100, which is attached to each of the outer peripheral portions of the shaft ring and is capable of performing a stretching or closing / contracting motion, is covered. The captive shaft sleeve 100 includes a left captive shaft sleeve 100a and a right captive shaft three. The hook 100b is connected to the bottom of the pivot 100c. A brake piece 101 is attached to the inner edge of the shaft sleeve, and one drive control device is attached to the upper end of the stationary shaft sleeve 100.

The drive control device is also shown in the structural view of the drive control device of the present invention in FIG. Two guide columns 103 and 104, each having a spring 108 fitted therein, are bored, and one positioning column body 105 is bored in the center of the fixed seat 102. One circular arc concave surface is formed on the right end of the positioning pillar 105, and the right ends of the two guide pillars 103 and 104 formed in the fixed seat 102 are both inserted into the drive seat 106 and fixed. Is determined. The drive seat 106 is extendable and retractable along the guide columns 103 and 104, and the top thrust body 107 on the middle drive seat 106 presses the arcuate concave surface of the positioning column body 105 on the fixed seat 102. The bottom surface of the drive seat 106 is fixed onto the right detaining shaft sleeve 100b, and the side end of the drive seat 106 is attached to a hydraulic line, for example, a pipeline for outputting the working fluid power of a pneumatic cylinder or a hydraulic cylinder.

When the high-pressure gas or hydraulic oil in the above-mentioned pipeline enters the inside of the driving seat 106 and presses the top thrust body 107 to extend it outward, the positioning column body 105 is pushed up. When the apex thrust force is larger than the compression force of the two springs 108, the drive seat 106 moves to the right together with the apex thrust body 107 by the thrust force in the direction opposite to the positioning column body 105, and the drive seats 106 and the right seat simultaneously move. The detent shaft sleeve 100b is rotated about the pivot 100c, whereby an extended state shown in FIG. 3 is formed between the left detention shaft sleeve 100a and the right detention shaft sleeve 100b, and the left detention shaft sleeve 100b is rotated. The brake piece 101 in the shaft sleeve 100a and the right holding shaft sleeve 100b cannot contact the outer edge of the shaft ring of the shaft coupling, that is, no braking action occurs.

However, once the working fluid in the drive seat 106 is inactive, the fixed seat 102 is compressed by the spring 108 and slides along the guide columns 103 and 104, and at this time, the top thrust body 107 of the drive seat 106 is pressed. Also, it does not contract to generate a top thrust, and the left holding shaft sleeve 100a and the right holding shaft sleeve 100b exhibit the closed state shown in FIG. At this time, the brake piece 101 on the bearing shaft sleeve comes into contact with the outside of the shaft ring of the shaft coupling to generate a braking action, and the extension / closing operation of the left bearing shaft sleeve 100a and the right bearing shaft sleeve 100b occurs. The braking force due to the binding of the bundles acts on the outer edge portions of the two shaft rings 109 of the shaft coupling, as shown in FIG. 5, and in this way the space between the main transmission shaft 110 and the transmission shaft 111 is surely secured. It is solidified and there are no gaps. Therefore, the impact phenomenon due to the gap between the transmission parts does not occur, and it is possible to prevent the impact stress due to the ordinary impact of the metal parts from shortening the operation life.
