Description

The invention relates to devices for stacking flat products and can be used in various fields of application.

A device for stacking flat products is known, comprising support posts, rotatably mounted levers, and a lifting and lowering table l.

A disadvantage of the known device is a thin actuator - electromagnets, turning levers on a signal from a photocell after dialing a complete package, which reduces the reliability of its operation.

The purpose of the invention is to increase the reliability of the device.

This goal is achieved by the fact that the device is provided with rods mounted on supporting posts with a possibility of moving in a vertical plane rods with pins, stops and cams mounted on the upper ends of the rods, fixed on one axis with levers with the possibility of interacting with said pins.

FIG. 1 shows the proposed device, a general view; in Fig.2 a section aa in Fig.1; in fig. 3. - the position of the levers when laying products; in fig. 4 - the same, when removing the foot.

The device consists of support pillars 1, a lifting and lowering table 2, levers 3,3 fixed with keys on axles 4, freely turning cix in slide bearings, stops 5 on which levers 3 rest, thereby limiting the rotation angle

10 axes 4, cams 6 and 7 fixed also with the help of dowels on axes 4 and interacting respectively with pins 8 and 9 located on the shifting in the vertical plane of the bone in the bearings of the rods 10 with the stops 11.

The device works as follows.

In the initial position, the center of gravity of the levers 3 ensures that they are supported on the surface B of the stops 5. The rods 10 occupy the lower extreme position. When lifting the product by lifting the lowering table 2, the levers 3 are pressed upwards by the product. When the product rises above the cams, they return to their original position due to their own weight. Lift, the product rests with an upper end against the stops 11 of the rods 10 and raises the latter.

During the reverse course of the lifting and lowering table, the product rests on the levers 3. The process is repeated until the complete set of the foot. When lifting the product, the stroke of the rod 10 supported by the stops 11 on the upper product increases by the height of the product. When the last product is lifted, the pins 8 interact with the cams b, turning them. At the same time, the levers 3, which are fixed on the same axis as the cams b, begin to turn, moving to the open position, i.e. The center of gravity of the levers 3 will be behind the axis of rotation. Under their own weight, the legs open and rest against the surface B of the stops 5. When the lifting and lowering table is reversed, the rod 10, lowering the products, begins to turn the cams 7 and pins 9 3. The centers of gravity of the levers move to their original position and the levers, the pads under their own weight, again push into the surface — into the stop 5. The rods 10 occupy the lowermost

position, the stop is lowered onto the conveyor.

The proposed invention is reliable in operation due to the absence of electromagnetic mechanisms in it and has a simple construction.
