The slide locating block 26 has a function of reducing friction and at the same time has a function of locating.

Preferably, four pointed positioning columns are fixed at four corners of the rectangular frame, and can puncture the opening of the cargo packaging bag 4 to fix the bag opening, so that the bag opening is opened to form a rectangular shape.

It should be noted that the goods packaging bag 4 usually adopts a product such as a woven bag, and the tip parts of the four tip positioning columns 231 can pierce the woven bag without being sharp, so that the tip parts of the four tip positioning columns 231 cannot hurt the skin of the human body, and the goods packaging bag is very safe and very convenient to fix.

In order to improve positioning accuracy, the bottom plate 20 of the bag collecting moving frame 2 and the bag collecting fixing frame 1 are respectively provided with a plurality of pairs of fine positioning devices, and each pair of fine positioning devices comprises:

one of the conical convex columns and the conical concave blocks is fixed with the bottom plate 20 of the bag collecting moving frame 2, and the other one is fixed with the bag collecting fixed frame 1;

the conical convex column can be embedded into the conical concave block, so that the bag collecting fixing frame 1 and the bag collecting fixing frame 1 can be accurately positioned.

Further, the unloading chassis 9 is fixed with a bag collecting moving frame 2 positioning device 91, when the bag collecting moving frame 2 is placed on the unloading chassis 9 by the bag collecting robot 84, the bag collecting moving frame positioning device 91 can fix the bag collecting moving frame 2, the bag collecting moving frame positioning device 91 is controlled by an unloading controller, and the unloading controller is connected with a server in a wired or wireless manner.

It should be noted that, dismouting goods wrapping bag 4 generally need exert certain power, and removal and installation convenience can be brought through fixed collection package removal frame 2, for example, when making the rectangle frame diminish hard, directly just can take out after breaking away from four cusp reference columns goods wrapping bag 4.

Preferably, the bag moving rack positioning device 91 includes:

the electromagnetic lock is provided with more than one pair and is symmetrically arranged relative to the bag collecting moving frame 2 and is electrically connected with the unloading controller;

the bottom plate 20 of the bag collecting moving frame 2 is made of magnetic conductive material, and the bottom plate 20 can be attracted by the electrified electromagnetic lock.

The electromagnetic lock selects the existing commodity, and when necessary, the switch is connected in series, and in the normal state, the electromagnetic lock is not electrified, so that when the cargo packaging bags 4 need to be manually loaded and unloaded, the electromagnetic lock is switched on through the switch, and the unlocking or locking time can be automatically controlled through the server.

The cargo sensor 6 includes:

the laser transmitting tube and the laser receiving tube are provided with a plurality of pairs and are horizontally arranged, and light beams emitted by the laser transmitting tube can be received by the laser receiving tube after being reflected by the goods 80.

The laser transmitting tube and the laser receiving tube are made of existing commodities, so that the control precision is high, and the power consumption is low.

The bag collecting robot 84 in the invention can accurately position and transport goods through a positioning system, wherein the positioning system comprises a wireless positioning system which collects the position information of the bag collecting robot 84 for accurate judgment; the two-dimensional code can be pasted on the bottom surface or the floor, the camera in the bag collecting robot 84 collects landmark information of the two-dimensional code to perform accurate positioning, the bag collecting movable frame 2 can be manually placed on the bag collecting fixed frame 1 through the bag collecting robot 84.
