SU1652236A1 - Device for controlling longitudinal grooves in conveyer belt - Google Patents

Abstract

The invention relates to belt conveyors, namely, means to control the longitudinal cuts of the conveyor belt (LC). The goal is to increase the reliability of control of cuts in LC. The device is located above LC 1 and includes a support 3 with a stand 4, rigidly connected to the frame of the conveyor 2. On the upper part of the stand 4 on hinges is installed having different lengths of arms The invention relates to belt conveyors, namely, means for controlling longitudinal tape cuts conveyor belt The aim of the invention is to increase the reliability of control of the cuts of the tape. FIG. 1 shows a section of the conveyor with a control device, front view; in fig. 2 — node I in FIG. one; in fig. 3 - a section of the conveyor, ID at the top. two shoulders lever (P) 9s with rollers 10, 11. Shoulders of two shoulders R 9 are installed with the possibility of rotation relative to each other. Between the shoulders P, there is a mechanism for adjusting their position relative to the LC and pressing it against it. The mechanism consists of coaxial Р 13, 14, and Р 13 is made hollow for free movement inside it Р 14. At the same time Р 13, 14 are pivotally connected with shoulders Р 9. Between themselves Р 13, 14 are connected by a spring 16, on one side rigidly attached to one of the arms of P 9, and on the other hand to the sensor for measuring the force of pressing the roller against the LC. At the time of the outburst of LC 1, one of the rollers 11, which is in the zone of the outburst, penetrates the incision. In this case, it rotates, turning the arm P 9 under the action of the potential energy of the tension spring 16. The latter is compressed, P 14 enters into P 13 and the sensor 18 signals a cut. 3 il. with Ј (L, The device is located under the conveyor belt 1 of the conveyor 2 and is fixed on the support 3 with the rack 4 rigidly connected to the frame of the conveyor 2. On the rack 4 on the hinges 5.6 there are arm arms 7.8 double-arm levers 9 turning relative to each other. The lever 8 is made in the form of a lattice, on the extreme slats of which a long roller 10 is attached. The levers / are independent and at the end of each are short rollers 11. About SL CO

Description

Rollers I1 can be one or several cents 1 located with a certain step iid width depending on which cuts need to be controlled: general or local.

Between the arms 8 and 7 there is a mechanism 12 for adjusting their position relative to the belt and pressing it against it. Fur} shzm 12 consists of coaxial levers 13 and 14, with the lever 13 being hollow for free movement inside the lever 14, the levers 13 and 14 attached to the levers 7.8 on the hinges 15, connected by a spring 16, rigidly on one side attached to the lever 7, for example, by means of a washer 17, and on the other hand - to the sensor 18 for measuring the force of pressing the roller to the tape with the possibility of adjusting the position of the spring 16 by the regulator 19. As such a sensor can be used.

The signal from sensor 18 characterizes the deformed state of spring 16 and controls the disengagement of the drive of conveyor 2,

In order to increase the reliability of the device's response when there is a general impulse to the right of the lever arm 7, a contact 20 is made in the area of its rotation, when closed, a signal is generated to disconnect the conveyor 2.

The device works as follows.

In the working position, the rollers 11 and 10 are in contact with the belt 1, the spring 16 is stretched by means of the regulator 19, i.e. on the levers 7, 8, a force is applied to the belt 1.

At the moment when the belt 1 rushes, one of the rollers 11, which is in the rush area, penetrates the p-section, the lever 7 turns under the latching of the potential energy pi inside the spring 16, the spring 16 contracts, the lever 14 enters deeper the lever 1J, the sensor 18 signals a cut, those. about necessity

disconnecting the conveyor 2. In addition, you can determine where the penta 1 is cut by the width of the mechanism 12 that the sensor responded to.

With the large dimensions of the belt 1, the lever 7 is deflected and causes the operation of the contact 20 operating according to the limit switch principle.

This device provides increased reliability of control of tape cuts during industrial operation due to the high sensitivity of the control mechanism and duplication of the process of disabling the tape drive during its cut.

Claims (1)

Invention Formula A device for monitoring the longitudinal cuts of the conveyor belt, including a support, a frame for fastening the support, rigidly connected to the last stand, on the upper part of which is a double arm with rollers having different lengths of arms, a sensor for measuring the pressing force of the rollers to the belt and A spring mechanism for adjusting the position and pressing the two shoulders to the belt, characterized in that, in order to increase the reliability of control of the tape cuts, the arms of the double arms are rotatably mounted. On the other hand, the mechanism for adjusting the position and pressing the two shoulders to the belt is made in the form of levers, one of which has a cavity and is hinged to one of the shoulders of the double shoulder, and the other is mounted for movement in the cavity of the lever and pivotally connected to the opposite shoulder of the two shoulders , wherein the spring is rigidly connected with one of the levers of the mechanism, and with the other by means of a sensor for measuring the force of pressing the roller against the tape. eleven Editor 3.
