The invention relates to a lifting machinery industry, namely to the drive of a conveyor intended for the periodic supply of a transported cargo, mainly for the supply of briquettes to electro-lubricating presses.

The aim of the invention is to increase the reliability of the drive.

Fig. 1 shows the kinematic drive circuit of the conveyor in Fig. 2, the end drum of the conveyor, cross section; fig.Z - drive conveyor in the initial position; in FIG. 4 -

the same in the acceleration position; FIG. 5, however, after the sign of the acceleration is reversed; Ia 6 - the same, at the end of the stroke; 7 - the same at idle ,. 20

The drive of the conveyor belt contains an electric motor 1 with a gearbox 2, a crank mechanism 3 and a carriage 4 carrying a pawl 5 having two working surfaces 6 and 7. The drive 25 drives the copier line 12 from below

They overtake the retarding assembly 5, and the strip 10, which follows after assembly 5, comes into contact with the working surface 7. From this moment, the movement of the entire system will, according to the law, be performed by the crank mechanism. Passing the stationary ruler 12, the roller 18 to the transition to the copier ruler 13 and, resting against the stop 14, moves along with the end of the working stroke, opening the rim of the copier rulers 12 and 13. idle the carriage 4 on the long surface of the movable cop of the ruler 13 The dog 5 retracts the positioning of the product 11 into the set position. At the same time, the roller 18 is removed from the stopped copier line of the pawl 5, which rests against the bar located behind it and rotates on the axis 17 and fails between the open lines 12 and 13. Next, roller 18

(Fig.7). At the end of idle speed, the tivovesh 16 puts the dog 5 to 20 to its original position. At the end of the stroke of the carriage 4, its plan returns the rod 15, and consequently, the movable copying line to its original position, the clamp of the copying surfaces of the rulers 12. Then the cycle repeats.

designed for a belt conveyor containing freely rotating drums 8, bending around two belts 9 interconnected by a series of identical strips 10 that are simultaneously clamps for products 11 placed on the belts 9. The drive also contains a fixed ruler 12 fixed on the conveyor frame and a ruler 13 with an anvil 14, 35 mounted on a rod 15 located in guides. The dog 5 is made with a counterweight 16 and is mounted to rotate on an axis 17 fixed to the carriage 4. At the same time, 40 dog 5 is provided with a roller 18. Dp to return the rod 15 to its original position on the carriage 4 a bar 19 is installed, to limit the swing of the dog 5 on the carriage 4 sections: stop20,45

The drive works as follows.

During rotation of the crank mechanism 3, the carriage 4, carrying the dog 5, receives a reciprocating motion. The working surface 6 of the pawl 5 comes into contact with one of the slats 10 and moves the belts 9 with the products 11 one step, while in the process of running the roller 18 first runs around the upper part of the copier ruler 12 ..-. One copier ruler, one of ko50

(Fig.7). At the end of the idle stroke, the counterweight 16 puts the dog 5 on the support 20 to its original position. At the end of the idling time of the carriage 4, its bar 19 returns the rod 15, and hence the movable cam line 13 to its original position, with the cam surfaces of bars 12 and 13 closed. Then the cycle repeats.

The performance of the copy lines {Open, and the dogs with two working surfaces allows acceleration,. slow down and stop the belt conveyor according to a law, thereby increasing the reliability of the drive.

Claims (1)

Invention Formula A conveyor drive comprising a carriage with a pawl mounted on it, associated with a reciprocating mechanism in horizontal guides mounted on the conveyor frame, characterized in that, in order to increase the reliability of the drive, it is equipped with carriages 4 located above the carriages. at the moment of changing the sign of acceleration of its movement, conveyor belts 9 with products 11, continuing to move by inertia, are first fixed to the frame of the conveyor stationary, and the other — by means of horizontal guides with the possibility of reciprocating peget copying line 12 below The slowing down dog 5 is overtaken, and the bar 10 located next to the dog 5 comes into contact with its working surface 7. From this moment on, the whole system moves according to the law of a crank drive mechanism. Pass the fixed copying ruler 12, the roller 18 goes to the copier ruler 13 and, resting against the stop 14, moves with it to the end of the working stroke, open the surface of the copier rulers 12 and 13. When the carriage 4 is idling, the working surface of the movable copier ruler 13 dog 5 pulls the tape 9, setting the product 11 to the specified position. In this case, the roller 18 slides down from the stopped copying line 13, and the pawl 5, abutting the surface 7 with the bar 10 located behind it, rotates on the axis 17 and falls between the open lines of the rulers 12 and 13. Next, the roller 18 runs around the copier line 12 from the bottom copied rulers, one of which (Fig.7). At the end of the idle stroke, the counterweight 16 puts the dog 5 on the support 20 to its original position. At the end of the idling time of the carriage 4, its bar 19 returns the rod 15, and hence the movable cam line 13 to its original position, with the cam surfaces of bars 12 and 13 closed. Then the cycle repeats. The performance of the copy lines {Open, and the dogs with two working surfaces allows acceleration,. slow down and stop the belt conveyor according to a law, thereby increasing the reliability of the drive. Invention Formula A conveyor drive including a carriage with a pawl mounted on it, associated with a reciprocating mechanism in horizontal guides mounted on the conveyor frame, characterized in that it is fitted above the four-turn hinges mounted on the conveyor frame fixed, and the other - by means of horizontal guides with the possibility of reciprocating ne 1400982 moving on them, with the dog com, and the carriage is made with emphasis, hinged on the carriage and made with counterbalance placed on its opposite ends and roller-mounted on it with the possibility of interaction with a movable copier ruler. t / / / /P 9 8 10 attached to it with the ability to interact with a movable copier ruler. 9ag.2 Vu, Z4 12 16 m P b sh, 1 cg 5
