Description

The invention relates to means of mechanization and automation of removal of products from the conveyor and stacking them in bags.

From the main 'ed. St. No. 781066, an automatic machine is known comprising a transfer carriage ⁵ and a longitudinal carriage located inside it with a gripper and a lifting mechanism, a synchronizer made in the form of a flexible _{| Q} th closed element with stops fixed to it, the carriage being longitudinally provided with a catch in contact with the stops a synchronizer kinematically connected _{on the} 15th with a conveyor mounted on a bed [Ί

A disadvantage of the known machine is that in case of failure of the electrical part 20 of the drive of the transfer trolley or limit switches at the moment when the hook and emphasis of the synchronizer are engaged, damage to the elements of the synchronizer or hook is possible.

The aim of the invention is to increase the reliability.

This goal is achieved by the fact that the machine is equipped with a copier installed in front of the synchronizer, and the trolley hook has a roller mounted by means of an axis with the possibility of contacting the roller during the movement of the hook.

In FIG. 1 shows a machine, a general view; in FIG. 2 - mutual arrangement of capture and products on the conveyor; in FIG. 3 ~ node I in FIG. 1 on an enlarged scale; in FIG. 4 - gearing mechanism, top view; in FIG. 5 “position of the roller on the copier, in which the hook disengages with the emphasis of the synchronizer.

The machine contains a frame 1, on which a transport trolley 2 is mounted, inside of which there is a trolley 3 of longitudinal movement with a gripper 3 963865 volume 4 and a lifting mechanism 5 thereof. A synchronizer is also mounted on the frame 1, made in the form of a closed flexible element 6 with stops 7 fixed on it and kinematically connected to the conveyor 8, for example, by a chain transmission 9 with a drive shaft 10 of the conveyor. The cart 3 of the longitudinal movement has a hook 11, periodically coming into contact with the stops 7 of the synchro-lowerizer. The hook 11 is equipped with a roller 12, mounted on the axis 13 and periodically rolling around the copy 14, mounted on the frame 1.

The machine operates as follows., 5 When the conveyor 8 with the products lying on it moves, the flexible element 6 of the synchronizer also moves. When one of the stops 7 comes into contact with the hook 11, the trolley 3 of longitudinal movement begins to move with the grip 4 located in the lowest position Above the conveyor 8 (see Fig. 2).

When the stop 7 with the hook 11 enters a straight section (see Fig. 3, the position of the hook and stop is shown by a dash-dot line), the speed of the cart 3 with the grip 4 becomes equal to the speed of the conveyor 8, and at this moment an impulse is applied to trigger the grip 4.

When moving the emphasis 7 of the trolley 3, the roller 12 of the hook 11 is rolled onto the copier 14 and begins to disengage the hook 11 from the stop 7 (see Fig. 5) ^{35 The} profile of the copier 14 should ensure that the hook 11 is disengaged from the gearing at a distance shorter than the freewheel trolley 3 · In the event of a failure of the electrical part of the drive of the transfer trolley 2 or limit switches, the roller 12 and the copier 14 will ensure that the flail 11 is withdrawn from engagement with the stop 7 at a certain position of the trolley 3.

In the future, the gripper 4 with the clamped products is moved by the lifting mechanism 5 above the conveyor 8 to the extreme position, after which the trolley 2 begins to move in the transverse direction. Having placed the products in the bag, the trolley 2 and the gripper 4 are returned to their original position above the conveyor 8. The initial and final positions of the longitudinal moving trolley 3 are provided with a copier (not shown in the drawing). The initial position of the trolley 3 and the hook 11 with respect to the synchronizer is shown in FIG. 3 · Next, the cycle repeats.

Thus, the proposed improvement of the known machine increases the reliability of its operation, since it eliminates the possibility of failure of the synchronizer or hook elements in case of failure of the electrical part of the drive of the transfer carriage or switches.

Claims (1)

The invention relates to the means of mechanization and automation of the removal of goods from a conveyor and putting them in bags. From the main author, sv. No. 781066 of the conventional machine comprising a transfer carriage and a longitudinal movement carriage located inside it with a hook and a lifting mechanism, a synchronizer made in the form of a flexible closed element with stops fixed to it, the longitudinal movement carriage provided with a hook in contact with the synchronizer stops, kinematically connected with the conveyor, mounted on a steel p. A disadvantage of the known automaton is that in case of failure of the electrical part of the drive of the transfer carriage or limit switches at the moment when the hook and the stop of the synchronizer are engaged, the elements of the synchronizer or hook may break. The aim of the invention is to increase the reliability of operation. This goal is achieved by the fact that the machine is equipped with a copier installed in front of the synchronizer, and the dolly hook is equipped with a roller mounted through an axis that can be in contact with the roller in the process of moving the hook. FIG. 1 shows the machine, general view; in fig. 2 - the relative position of the grip and products on the conveyor; in fig. 3 shows the node I in FIG. 1 on an enlarged scale; in fig. - meshing mechanism, top view; in fig. 5 position of the roller on the copier, in which the hook is disengaged from the synchronizer stop. The machine contains a frame 1 on which the transfer carriage 2 is mounted, inside which the carriage 3 is placed with a longitudinal movement from the pick-up volume k and the lifting mechanism 5 thereof. A synchronizer is also mounted on the frame 1, made in the form of a closed flexible element 6 with stops 7 fixed to it and kinematically connected with a conveyor 8, for example, a chain gear 9 with a drive shaft 10 of the conveyor. The carriage 3 of the longitudinal movement has a hook 11 periodically coming into contact with the stops 7 of the synchro nizer. The hook 11 is provided with a roller 12, planted on the axis 13 and periodically rolling around on the copier mounted on the frame 1. The machine works as follows. When the conveyor 8 moves with the products lying on it, the synchronizer flexible element 6 moves. When one of the lugs 7 comes into contact with the hook 11, the longitudinal carriage 3 begins to move with the grip k in its lowest position above the conveyor 8 (see Fig. 2). When the stop 7 with the hook 11 goes to the straight-line section (see Fig. 3, the position of the hook and the stop is indicated by the dash-dotted line), the speed of movement of the carriage 3 with the grip k becomes equal to the speed of movement of the conveyor 8, and this moment impulses to engage the grip. When moving the stopper 7 of the carriage 3, the roller 12 of the hook 11 rolls onto the copier k and starts disengaging the hook 11 from the engagement with the stopper 7 (see Fig. 5) The profile of the copier 1 must. Allow the hook 11 to be disengaged from a distance less than the free path carts 3- In case of failure of the electric part of the drive of the carriage 2 of the transfer or the limit switches roller 12 and copier W will provide the output of the chain 4 from the gear with the stop 7 at a certain position of the carriage 3. Subsequently, the grip 4 with the clamped products is moved by the lifting mechanism 5 above convoy The driver 8 to the extreme position, after which the carriage 2 begins to move in the transverse direction. Having placed the products in the bag, the carriage 2 and the grip k return to their original position above the conveyor 8. The initial and final position of the carriage 3 of the longitudinal movement is provided by a copier (not shown in the drawing). The initial position of the carriage 3 and the hook 11 with respect to the synchronizer is shown in FIG. 3. Then the cycle repeats. Thus, the proposed improvement of the known automaton increases the reliability of its operation, since it excludes the possibility of breaking out of the elements of the synchronizer or hook in case of failure of the electrical part of the drive of the transfer carriage or limit switches. The invention The machine for removal of products from the conveyor and packing them in packages by author. St. No. 781066, characterized in that, in order to increase its reliability in operation, it is provided with a copier installed in front of the synchronizer, and a trolley hook with a roller, which is installed through an axis with the possibility of contact with the copier during the process of moving the hook.
