The rack 33 is perpendicular to the support plate 1, and a slider 34 is arranged on the opposite side of the gear engagement surface, the slider 34 is fixed on the support plate 1, and the rack 33 can move up and down along the slider 34.

The number of the grabbing groups 4 is six. The grabbing group 4 consists of a lifting sleeve 41 and a plurality of pins 42. The lifting sleeve 41 is cylindrical, the upper part of the lifting sleeve is fixed with the tail end of the rack 33, and a plurality of pins 42 are uniformly distributed along the circumferential direction below the lifting sleeve. The pins 42 are vertically arranged, and two bending angles with opposite directions are formed in the vertical direction, so that the pins are divided into an upper section, a middle section and a lower section. Wherein, the upper section and the lower section of the contact pin 42 are both vertical, the upper section is fixed with the lifting sleeve 41, and the tail end of the lower section is designed as a pointed end; the middle section is an inclined part, and the surface roughness of the middle section from bottom to top is gradually increased.

The working process of the gripping device of the compatible palletizer according to the present utility model is described in detail below by way of examples.

Examples:

before grabbing the pug, as shown in fig. 1, the pins 42 are located inside the mud guard 5. When the pugs need to be grabbed, the servo motor 21 operates to drive the driving worm 23 to rotate in the forward direction, and meanwhile, the driven worm 26 is driven to rotate in the forward direction through the synchronous belt 25. The driving worm 23 and the driven worm 26 are driven to rotate the worm wheel-gear shaft 31 at each position, so that the rack 33 and the lifting sleeve 41 fixed with the rack 33 move downwards, and the contact pin 42 extends out of the mud-guard sleeve 5, as shown in fig. 2. The pin 42 is inserted into the pug to complete the pug gripping operation. When the mud is required to be stacked, the servo motor 21 drives the driving worm 23 and the driven worm 26 to reversely rotate, the contact pin 42 is retracted, and the mud falls into a stacking position under the action of the mud blocking sleeve 5.

It should be noted that, the distance of the extension of the pin 42 can be precisely controlled by the servo motor 21, and because the middle section of the pin 42 has a certain inclination angle and the roughness of the pin 42 is different at different positions, the depth of the pin 42 inserted into the mud can be flexibly adjusted according to mud with different viscosities, so as to ensure reliable grabbing of the mud. In addition, the embodiment is described taking a 3×2 stacking form as an example, and the utility model can accomplish stacking in various forms by changing the arrangement form of the power driving group 2 and the power transmission group 3 and increasing or decreasing the number of the grabbing groups 4.

The embodiment shows that the grabbing and stacking device compatible with the mud materials with different viscosities can still reliably finish grabbing and stacking work aiming at the conditions of different viscosity, irregular shape, error position and the like of the mud materials.
