Detailed Description

As shown in fig. 1-3, the backstop claw for the tray stacker crane is specifically designed into a 7-shaped right-angled shape and comprises a horizontal part and a vertical part which are connected into a whole, pin shaft holes 2 are arranged at the corners of the horizontal part and the vertical part, and the vertical part is kept to be vertically placed downwards in a self-weight state; during operation, the pin penetrates through the pin shaft hole 2 and then is connected to the rack of the tray stacker crane.

Specifically, the length of the vertical part is more than or equal to 1.62 times of the length of the horizontal part, so that the vertical part is kept in a vertical downward state all the time without being influenced by external force. The top surface of the horizontal part is provided with a horizontal supporting surface 1 for supporting the tray and limiting the tray to keep the tray stable; the corner side of the horizontal part is provided with a guide inclined plane 3, so that the friction drive when the tray is lifted is convenient to drive the rotation and guide of the non-return claw; the horizontal part and the outer edge fillet that vertical portion is connected, the lateral surface of vertical portion sets up to end contrary face 5, set up to second inclined plane 4 between the medial surface of the corner of vertical portion and the bottom horizontal plane, end contrary face 5 with the bottom horizontal plane of vertical portion is perpendicular. The included angle between the guide inclined plane 3 and the horizontal supporting surface 1 is set to be alpha, the alpha is specifically designed to be 25-45 degrees, and 35 degrees is preferably selected.

as shown in fig. 4-7, a method for using non-return claws to achieve pallet stacking positioning by using the non-return claws, firstly, four non-return claws are symmetrically arranged and mounted on a rack 6 of a pallet stacker, two of the non-return claws are mounted on the left side of the rack, and two of the non-return claws are mounted on the right side of the rack, when the non-return claws are mounted, a gap with a width of L is arranged between a non-return surface 5 and the inner side surface of the rack 6, and a support seat 8 for preventing reverse rotation is arranged on the rack, and the support seat 8 can be designed to be round or square and is positioned in the gap between the non-return surface 5 and the rack 6 to position the rotation direction of the non-return. Specifically, the size of the width L is related to the size of the non-return claw, the specific specification of the non-return claw is determined by the tray to be stacked, and the non-return claw not only can rotate and stack the tray and support the tray, but also can reset by dead weight and does not interfere with the rack.

the specific operation steps during the stacking of the trays are as follows:

step one, stacking trays: the tray 7 is positioned below the non-return claw, and the stacker crane can stack a plurality of trays 7 through the second inclined plane 4; the specific seat tray is finished by one stacking, only one tray can be stacked at a time, 5 or 6 trays (different requirements of logistics distribution processes of different automobile factories) are stacked in total, only one tray is conveyed by the conveyor according to the process requirements of an automatic production line, and only one tray can be lifted by the tray lifter of the stacker crane;

step two, lifting the tray: after stacking, a lifting machine on the stacker crane drives a tray 7 to move upwards, two sides of the tray 7 rub the guide inclined planes 3 and drive the non-return claws to rotate clockwise or anticlockwise around the positioning pins in the pin shaft holes 2, when the tray 7 rotates to a position that the height of the tray is higher than the height of the horizontal plane of the non-return claws, the tray continues to rise, and when the horizontal plane of the non-return claws rotates clockwise or anticlockwise by 45 degrees, the tray is separated from the non-return claws, as shown in fig. 6;

thirdly, the tray falls: the non-return claws are reset by self weight after losing external force, at the moment, the lifting machine lifts the tray to descend, the tray is placed on the horizontal supporting plane 1 of the four non-return claws, the non-return claws support four plane points of the tray 7, and the lifting and stacking operation of one tray is completed;

And repeating the above operation steps to finish the stacking operation of a plurality of trays.

The non-return claw for the tray stacker has the advantages of ingenious design, simple structure and reasonable utilization of the characteristic of dead weight and droop, can quickly realize the conveying and positioning switching of products, meets the functional requirements in the shortest time and achieves the best effect.

specifically, as shown in fig. 1 and 4, the designed tray 7 for the stacking seats has the length dimension of 1800mm, the width dimension of 900mm, the length interval of the frame is 1810mm, the width interval is 911mm, the horizontal length dimension of the non-return claws is 74mm, the vertical length dimension is 120mm, the length interval of the two non-return claws is 1748mm (the tray is 1800mm to ensure that the tray is supported), the width interval is 560mm, and the length ratio of the vertical part to the horizontal part is 1.62; and a gap is arranged between the non-return surface 5 and the inner side surface of the frame 6, and the width L value of the gap is 33 mm. The specification of the non-return claw can be adjusted according to the size of the actual tray, and the corresponding alpha, the length proportion of the vertical part and the horizontal part and the size of the L are correspondingly adjusted.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
