The following describes in detail the steps of using a high efficiency stacker with a tire stacker as described herein with reference to fig. 1 to 11:

at the beginning, the stacking goods shelf can be placed according to the placing mode of the goods shelf in a common warehouse, the right side of the stacking goods shelf faces to the channel of the stacker, the sliding rod 17 is located at the lower limit position, the first spring 20 is located at the stretched state under the action of self weight, the stacking of the lower layer is prevented from being affected while the stacking is facilitated, the rotating rod 27 is located at the lower limit position, the ratchet wheel disc 29 and the ratchet wheel 30 are in the matched state, and the second pull wire 34 is located in the loose state.

When the stacking machine works, the third motor 55 is started according to the specification of tires to be stacked, so that the sliders 50 at the front side and the rear side are driven to move towards or away from each other through worm gear transmission and thread transmission, the sliders 50 at the front side and the rear side are enabled to be at proper positions, when the spare space on the stacking shelf is large, the extension of the telescopic support rod 52 is controlled by one layer, the length of the telescopic support rod 52 is equal to that of the two first arc-shaped plates 15, the quantity of two groups of tires can be stacked at one time, the stacking efficiency is improved, a plurality of tires are placed on the telescopic support rod 52 in a standing state through other mechanical devices or manual modes, then after the stacking machine runs to the stacking shelf position, the tires are firstly lifted, so that the lower end of the telescopic support rod 52 is higher than the upper end of the first arc-shaped plate 15 at the layer, the free space of the shelf is large at the moment, and under the condition that enough space is reserved to avoid collision between the telescopic support rod 52 and the support column 11, the second motor 47 is started to drive the supporting plate 46 to rotate, so that the extended left end of the telescopic supporting rod 52 and the tire are positioned in the stacking shelf layer, then the telescopic supporting rod 52 continues to extend and move towards the shelf layer, the position of the stacker is adjusted so that the lower end of the tire is right opposite to the upper end of the first arc-shaped plates 15, and the stacker is controlled to slightly descend to place the tire on the two first arc-shaped plates 15;

then under the action of the pressure sensor, the first motor 23 is started to drive the first wire coiling wheel 24 to rotate and coil the first wire 25, so that the slide rod 17 is pulled up to the upper limit position, the position of the slide rod 17 is kept unchanged under the self-locking action of the first motor 23, in the process that the second arc-shaped plate 18 ascends along with the slide rod 17, the distance between the second arc-shaped plate 18 and the first arc-shaped plate 15 avoids the contact between the telescopic supporting rod 52 and the first arc-shaped plate 15, in the process, the elastic friction wheel 40 firstly contacts with the circumferential end surface of the tire and rotates, so that the third wire coiling wheel 41 rotates and coils the second wire 42, so that the rotating rod 27 and the limiting rod 28 rotate, in the case that the tires are simultaneously placed on the two first arc-shaped plates 15, when the limiting rod 28 on the left side is blocked by the tire on the right side in the rotating process, the limiting rod 28 on the right side is overturned to be in a state that the axis of the tire is vertical to be abutted against the tire, in a state where the ratchet plate 29 is engaged with the ratchet 30, the stopper rod 28 cannot be rotated reversely, thereby preventing the tire from falling down.

If the free space on the stacking shelf is small, and under the condition that the telescopic supporting rod 52 does not have enough space to rotate in the extending state, the number of tires which can be placed by one first arc-shaped plate 15 is stacked on the telescopic supporting rod 52 at the last time, and when a group of tires are placed on the left first arc-shaped plate 15, the left limiting rod 28 can normally run to prevent the tires from toppling over, and the condition that normal stacking is hindered when the tires are stacked on the right first arc-shaped plate 15 is avoided.

When the tires need to be taken down, the stacker stops to a proper position to control the telescopic supporting rod 52 to extend and start the signal transmitter, the signal receiver receives a signal and then the electromagnet 58 starts, at the moment, the electromagnet 58 and the ratchet wheel 30 are attracted, the attraction is larger than the game force between the metal block 35 and the magnet 36, so that the ratchet wheel 30 is separated from the ratchet wheel disc 29, the rotating rod 27 is unlocked and can rotate freely, and the tires can be moved out of a stacking shelf at the moment;

when the ratchet mechanism is reset, the electromagnet 58 is powered off, the second pull wire 34 is firstly tightened by the attraction force of the metal block 35 and the magnet 36, so that the ratchet 32 is retracted into the ratchet cavity 31, the ratchet 30 and the ratchet disc 29 are matched again without obstruction, and when the ratchet 30 is reset to be at the lower limit position, the second pull wire 34 returns to the loose state, so that the ratchet mechanism cannot reversely rotate after being reset.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
