In the description of the present invention, it should be noted that, if the terms "upper", "lower", "inner", "outer", and the like indicate an azimuth or a positional relationship based on the azimuth or the positional relationship shown in the drawings, or the azimuth or the positional relationship in which the inventive product is conventionally put in use, it is merely for convenience of describing the present invention and simplifying the description, and it is not indicated or implied that the apparatus or element referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus it should not be construed as limiting the present invention.

Furthermore, the terms "first," "second," and the like, if any, are used merely for distinguishing between descriptions and not for indicating or implying a relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

In the production enterprises such as white spirit, food beverage, daily chemicals, etc., the unstacking letter sorting of goods and loading link working strength are big, and the recruitment cost is high, and automatic transport loading equipment becomes the demand hotspot. The materials of the box cargoes are generally paper box packages, the shapes of the box cargoes are fixed, but the box shapes with various sizes and large weight differences bring great challenges to loading and conveying.

In the loading systems provided in the patents CN 201811559602.5, CN 201921775147.2 and CN 202022637461.3, a loading transfer mechanism and a stacking device are provided. The container is conveyed to the stacking device by the loading conveying mechanism, and then the stacking task is completed by the stacking pushing mechanism and the code disc. Wherein the loading conveying mechanism is provided with a centering device, and the stacking device is provided with a left-right distributing device. The defects of the container conveying mode and the stacking mode are as follows:

(1) when an even number of containers can be accommodated on the coded disc, and the width of each container is half of the width of the entrance of the coded disc, the last container cannot enter the coded disc because the previous container occupies the entrance position, and aiming at containers with the specification, the coded disc can only finish simultaneous stacking of an odd number of containers, and the even number of containers cannot be stacked, so that each row of containers of a truck is reduced, and the space utilization rate and the truck loading efficiency of the truck are reduced;

(2) the space positions of the left and right distributing devices of the stacking tray can limit the boxing height of the top of the van or the container type van, so that the space utilization rate of the van is reduced;

(3) when the left and right allocating devices move, the container temporarily stops entering the code wheel, so that the loading frequency is limited, the overall loading efficiency is reduced, and meanwhile, the loading stability is also reduced;

in CN 202022637461.3, CN202011275978.0 and CN202210880242.9 patents, the loading operation is performed on the front position by using three structural modes of long arm, frame forward moving long arm and two-stage large arm, and when loading a truck with a gooseneck platform, the gooseneck platform is long, long large arms are required, so that many problems exist:

(1) the overlong large arm makes the loading robot body longer and has space limitation;

(2) when the coded disc is used for loading a container, the longer large arm needs to bear large moment, and corresponding counterweight is needed to balance the coded disc;

(3) the large arm travel is longer and the speed is slower in the case of larger moment, resulting in inefficiency.

In addition, the loading height, the side stacking and the mixed stacking of the box type truck and the container type truck are all the time the difficult problems to be solved immediately at present, the container loading cannot be stacked and embossed and stacked by the side wall of the carriage, and the goods can shake integrally during transportation, so that great potential hazards exist in industries such as drinks and the like.

In order to improve the above technical problems, a two-stage loader and a loading method are provided in the following embodiments.

Referring to fig. 1, the present embodiment provides a two-stage loading machine 10, which is capable of loading and unloading a gooseneck platform 51 of a carriage, and includes a front-stage loading robot 300 and a rear-stage loading robot 200.

The front section loading robot 300 comprises a front section frame 310, a jacking roller assembly 320 and a code wheel assembly 370;

the jacking roller assembly 320 is connected with the front section frame 310 in a lifting manner, and the jacking roller assembly 320 can move on the carriage along a first direction; the code wheel assembly 370 is movably disposed on the front frame 310 to finish goods and to stack the goods;

the rear loading robot 200 includes a chassis 210 and a forward boom assembly 240, the chassis 210 being movable in a first direction on the platform 52 of the carriage; the front arm assembly 240 is movably connected with the chassis 210, and the front arm assembly 240 can extend out of the chassis 210 along a first direction;

the forward boom assembly 240 is coupled to the forward frame 310 to enable the forward loading robot 300 to move on the gooseneck platform 51 and the platform 52.

The front loading robot 300 of the two-stage loading machine 10 of the scheme can rise to the height of the gooseneck platform 51 of the carriage and descend to the height of the flat plate platform 52 of the carriage under the action of the jacking roller assemblies 320; the front boom assembly 240 of the rear loading robot 200 can push the front loading robot 300, so that the front loading robot 300 can move on the gooseneck platform 51 or the flat plate platform 52 through the jacking roller assembly 320, thereby realizing the up-and-down of the gooseneck platform 51 by the front loading robot 300. The code wheel assembly 370 provided on the front loading robot 300 can finish and stack goods. So realized through removing anterior segment loading robot 300 to the preset position of gooseneck platform 51 and carry out cargo pile up neatly again, compared with the condition that whole carloader in the prior art only can remove and lead to the big arm overlength on flat board platform 52, such two segmentation carloader 10 can be showing shorten big arm stroke length, has alleviateed corresponding counter weight, and cargo pile up neatly efficiency is higher.

In particular, please continue to refer to fig. 1-8 for more structural details of the two-stage loader 10.

It should be noted that: in the component description, the direction of the truck head is taken as the front, the position of the hydraulic lifting platform 30 is taken as the rear, and the left side is left and the right side is right when the position of the hydraulic lifting platform 30 is seen forwards.

As can be seen in fig. 1, the two-stage loader 10 includes a front-stage loading robot 300 and a rear-stage loading robot 200. The rear loading robot 200 is connected to the telescopic belt conveyor 20 through a telescopic conveying line and is used for receiving a container which is unstacked and conveyed or directly receiving a container on a product conveying line. And (3) stacking single or multiple stacking trays on the loading machine according to the specification and stacking requirements of the container, so that embossing stacking is realized. The position of the two-section loading machine 10 on the carriage is controlled by the crawler travelling mechanism, and each station can finish 2 rows of container stacking and sequentially back until the cargo stacking work of the whole carriage is finished.

200 rear loading robot 200: the crawler belt mainly comprises a crawler belt chassis 210, an accumulation conveying line 220, a differential conveying line 230, a front extension arm assembly 240, a locking assembly 250, a rear side supporting leg 260, a lifting adjustment assembly 270, a rear end limiting device 280 and a front extension power assembly 290. The rear loading robot 200 can move back and forth along the first direction as a whole, and can also push the front loading robot 300 to move back and forth, and can adjust the lifting of the conveyor line of itself to match the height change of the telescopic belt conveyor 20.

The first direction is the longitudinal extension direction of the vehicle cabin.

The specific 210 chassis 210 is used as a walking carrier of the whole loading robot, walks on a carriage, and is matched with the stacking rhythm of the system, and retreats station by station until the stacking task is finished. The chassis 210 here is a crawler chassis 210 that moves on a carriage by a crawler running mechanism. Alternatively, the entire travel drive of the crawler 210 is controlled by two servo motors. The travelling mechanism of the embodiment is a rubber crawler chassis 210, which has the characteristics of stable travelling, good adaptability to travelling road surfaces and strong load capacity.

The accumulation conveyor line 220 is used for receiving cargoes, and the differential conveyor line 230 is arranged at one end of the accumulation conveyor line 220 close to the front section loading robot 300; the conveying speed of the differential conveying line 230 is greater than that of the accumulation conveying line 220.

Specifically, the accumulation conveyor line 220 is connected to the telescopic belt conveyor 20. The cases fed from the telescopic belt 20 can be accumulated therein. Because the box spacing on accumulation conveyor line 220 is tight, differential conveyor line 230 is faster, pulling the box distance apart for subsequent processing.

The forward boom assembly 240 is coupled to a front frame 310 of the front loading robot 300 to power the front loading robot 300 to travel forward and backward. Note that, the accumulation conveyor line 220, the differential conveyor line 230, and the rear leg 260 are disposed on the front arm assembly 240.

The locking assembly 250 is disposed between the forward boom assembly 240 and the chassis 210. The current loading robot 300 is retracted from the gooseneck platform 51 (at this time, the conveyor line 220 is accumulated and the forward boom assembly 240 is retracted to the proper position), the locking assembly 250 locks the conveyor line, the impact caused by shaking of the frame is reduced, and the overall stability is improved.

260 the rear legs 260 are disposed below the forward boom assembly 240. In this embodiment four rear legs 260 are movably in the rail slots to support the entire accumulation conveyor line 220, differential conveyor line 230 and forward boom assembly 240. The rear leg 260 can be used to leg the vehicle when the accumulation conveyor line 220, the forward boom assembly 240, is extended forward.

270 the lift adjustment assembly 270 is disposed between the forearm assembly 240 and the chassis 210. I.e., the chassis 210 and the forearm assembly 240 may be in a lifting engagement. When the two-stage loader 10 moves forward and backward, the telescopic belt conveyor 20 can synchronously extend or retract, and the inclination angle of the telescopic belt conveyor 20 can be changed, and the lifting adjustment assembly 270 provides lifting to adapt to the height change of the telescopic belt conveyor 20.

The rear end stop 280 is disposed at the end of the rail groove 280. The rear end stop 280 prevents the rear leg 260 from backing out of the rail groove.

290 the reach power assembly 290 provides reach and retract power (pulling the front loading robot 300 forward and backward) to the reach arm assembly 240.

300 front loading robot 300 includes a front frame 310, a jacking roller assembly 320, a large arm assembly 330, a counterweight assembly 340, a forward extending assembly 350, a small Z-axis assembly 360, a code wheel assembly 370, an inner conveyor line assembly 380, and a lifting power assembly 390. The bottom of the front frame 310 is provided with a plurality of rollers 311.

It can also be seen that the forward boom assembly 240 is movably coupled to the front frame 310 along the height of the front loading robot 300. Optionally, the front section frame 310 has a slide rail disposed along a vertical direction, and an end of the front boom assembly 240 near the front section loading robot 300 has a slider. The sliding block is in sliding fit with the sliding rail, so that the front-section loading robot 300 can move along the vertical direction, and stability of the front-section loading robot 300 when lifting relative to the rear-section loading robot 200 is ensured.

The front loading robot 300 is connected to the rear loading robot 200 through the front arm assembly 240 and is capable of walking on the gooseneck platform 51 alone (supported by the rollers 311 on the front frame 310 with the push-pull force of the front arm assembly 240 as a motive force).
