Description

2. A device according to claim 1, characterized in that each shoulder of the three-arm lever has a roller at its end.

3. The device according to claim 1, which is based on the fact that each of the stops is made with a protrusion.

The invention relates to the technological equipment of enterprises of the construction industry and is intended for the movement of goods, for example, trolley molds at technological posts. A device for moving loads is known; they will contain its TOLFWARE with the stops interacting alternately on the load, and the mechanism for installation of the supports with the SP drive. However, when the drive is positioned, the mechanism for placing the stop on the pusher causes the inconvenience of energizing it and the reliability of operation decreases, as the tick, like moving the pusher ps, powerful hoses (hydro, pneumatic, etc.) quickly fail. In the case of the arrangement of the drive of the mechanism for the installation of the stops separately from the outflow of the pushers, there is a difficulty in ensuring their joint operation. In addition, the proposal does not address the issue of simply reducing the load at idle pusher. The closest to the invention is a device for moving weights, holding a push rod with two capable of reciprocating movement. multi-directional one-way lugs hinged on it and a mechanism for mounting the lugs with a shift lever, lugs mounted on the lever pivot / limiter and pivotally connected to the fixed base and between each other and the jaj4ara t21 switch. The known device does not provide the movement of cargo in conveyor lines with a dead-end layout of posts. This happens because the drive of the movement of the pusher is constant, it corresponds to the step of loading the load, and if the device is installed at dead ends, reversing of the load will not occur, because the stops are installed on one common axis and the stop of the load does not allow drive pusher due to the fact that the drive stroke is already over. In addition, the device does not provide reversible movement of the same load, since it is impossible to switch the stops because one of them is constantly in contact with the protrusion of the load. As a result, the device has narrow technological capabilities. The aim of the invention is to expand the technological capabilities of the conveyor. This goal is achieved by the fact that in the device for moving loads, there is a pusher mounted with the possibility of reciprocating movement with two multidirectional stops of a unilateral action fixed to it and a mechanism for installing the stops with an lever for switching the stops mounted on the pusher, limiters of rotation of the valve and pivotally connected to a fixed base and between each other by a drive and an Eichaga switch, the lever switch is made in the form of a plate with unequal cams which is mounted on the base by means of parallel levers, with the stops fixed to the pusher by means of parallel axes, and the switch lever is three-arm and the two arms of the lever are interoperable with the corresponding stop / third arm; with the cams of the plate. . In addition, each shoulder of the three-arm arm of its lever has a roller at the end. In this case, each of the stops is made with a protrusion. FIG. 1 shows schematically the proposed device (moving the load to the right by two steps); in fig. 2 - a pusher unit with an installation mechanism for the stops; FIG. 3, section A-A in FIG. 2; in fig. 4 is a diagram of the operation of the pusher when the load moves to the right; FIG. 5 - the same, when moving the load to the left. The device comprises a fixed base 1 with mounted on it with the possibility of reciprocating movement in the guides 2 of the pushers 3,4. The pushers 3 and 4 have a drive 5 and are interconnected by a chain drive 6. Each pusher 3,4 is made of housing 7 with two hingedly mounted multidirectional single-acting stops on the middle of parallel axes 8 — left stop 9 and right stop 10. Each stop provided with protrusions 11 and a counterweight 12. The installation mechanism for the stops, including the lever for switching the stops mounted on the pushers 3 and 4 on the axis 13, made in the form of a three-lever arm 14 with rollers located on each shoulder 15, 16 and 17, mounted on the housing 7 restrict whether 18 rotates the lever 14. In addition, the mechanism for mounting the stops contains pivotally connected with the fixed base 1 and between them the drive 19 and the switch 20 of the lever 14, made in the form of a plate 21 with uneven cams high 22 and low 23. The plate 21 is fixed pivotally on base 1 on two parallel levers 24. At the same time, two arms 16 and 17 of three arms can be combined with the corresponding support 9 and 10, and the third shoulder, 15 - with cams 22 and 23 of the plate 21. The chain transmission 6 consists of flail 25, round sprocket 26. The forward load is provided with stops 27- ,. installed in increments equal to the step of movement of the pusher minus stand necessary for the passage of the ynopai pusher under the rest of the load and the vertical position. The operation of the device is as follows. In the initial position, the pushers 3 and 4 are adjacent (Fig. 1). When reloading the load to the right, the drive 5 of the pushers 3, 4 moves the pusher 3 to the left (idling); the pusher 3 connected to the lower branch of the chain 25 moves the pusher 4 connected to the upper branch of the chain 2 to the right. In this case, the left stop 9 sense. tel 4 moves the load to the right. During the return stroke of the drive 5, the left stop 5 of the pusher 3 moves the load to the right, and the coupler 4 connected to the chain 25 is shifted to the left (idle one turn). Then the cycle repeats. ; To move the load to the left. right stop 10 pushers 3,4; the rest of the device operation is repeated. The transfer of the stops 9 and HE is carried out by the mechanism for installing the stops as follows. When the load moves to the right (Fig. 4), the actuator 19 moves the plate 21 to the extreme left position, while the low cam 23 approaches the shoulder 15 of the three-armed p 14 chaga 14. At the beginning of the movement of the pusher 4 to the right shoulder 15c with the roller, resting against the cam 23, turns the lever 14 around the axis 13 to the limiter 18, while the roller of the shoulder 16 comes off the protrusion 11 of the left support 9, releasing it. The stop 9 under the action of the counterweight 12 rotates around the axis 8 and occupies a vertical (working) position, and the roller of the shoulder 17 advances on the protrusion 11 of the right stop 10, causing the latter, turning, to take a horizontal (not working) position. Move further, left stop 9 moves the load to the right. When moving the pusher 4 backwards (idle), the shoulder 15 passes over the cam 23 (three shoulders E), step 1 14 remains at rest. The left stop 9, the passage under the stop, 27 of the load, rotates freely around the axis B and returns to the working position after the passage of the stop 27 of the load. When moving the cargo to the left (figure 5), the actuator 19 moves the plate 21 to the extreme right position. At the same time, the high cam 22, resting against the shoulder 15 of the three-arm lever 14, rotates it around the axis 13 to the limiter 18. The roller of the shoulder 17 leaves the protrusion 11 of the right support 10, releasing it, and the roller of the shoulder 16 moves to the projection 11 of the left support 9 and forces It cannot be horizontal. The pusher 4 moves to the right (idle). The shoulder roller 15 passes over the low cam 23, as the plate 21, moving to the right on the parallel arms 24, is lowered. The right stop 10 passes under the load rest 27, turning around, axis 8, and returns to the working position. When moving, the pusher is back (working stroke), the stop 10 moves the load to the left. The proposed device provides for the movement of cargo in conveyor lines with a dead-end layout of posts. In addition, it is reliable in the work when reversing rewinding of the same load.
