Description

Automatic AGV dolly of loading and unloading goods

Technical Field

The invention relates to the technical field of logistics storage and transportation equipment, in particular to an AGV (automatic guided vehicle) capable of automatically loading and unloading goods.

Background

An automatic Guided Vehicle (generally referred to as an AGV Vehicle) is a Vehicle equipped with an electromagnetic or optical automatic guiding device, which can travel along a predetermined guiding path, and has safety protection and various transplanting functions.

At present, the path control of the AGV car is mature day by day, but the automatic loading and unloading function of the AGV car for goods is still incomplete. A Chinese patent of an automatic loading and unloading device of an AGV (publication No. CN 208360011U) is characterized in that a swinging mechanism and an object placing disc are arranged on a chassis of the AGV, the object placing disc is driven by a motor to incline towards two sides, the technical defect that the AGV cannot topple from two sides so as to load and unload goods is overcome, an adopted mechanism is simple and easy to realize, the automatic loading and unloading of the goods cannot be realized, and the full automation of the AGV cannot be achieved.

A Chinese patent of AGV capable of freely rotating and automatically loading and unloading goods (publication number CN 208814077U) is characterized in that a goods loading and unloading mechanism is arranged on the upper side of a vehicle body, three panels are arranged, the panels are connected through an electric telescopic rod, a turntable is arranged at the bottom of a supporting plate, the upper side of the vehicle body can be freely rotated through the turntable, the functions of automatically loading, transporting and unloading are realized through a goods loading and unloading device capable of freely rotating, but the structure of the AGV is too complex, the automatic loading and unloading speed is low, the real-time unloading of the dolly cannot be realized, and the speed is not uniform in the driving process of the dolly.

Disclosure of Invention

The invention aims to provide an AGV trolley capable of automatically loading and unloading goods, which can automatically load and unload the goods and improve the working efficiency.

The technical scheme adopted by the invention for solving the technical problems is as follows:

an AGV trolley capable of automatically loading and unloading goods comprises a trolley body, wherein front wheels and rear wheels are arranged at the bottom of the trolley body, a bearing platform is arranged at the top of the trolley body, one side, located on the front wheels, of the bearing platform is a downward slope, and a semicircular goods baffle is arranged on one side, located on the rear wheels, of the bearing platform; the slope is provided with a goods conveying belt, the outer end of the slope is provided with a fork, and the fork can be turned upwards; bearing platform still the interval is equipped with the first goods transport area of horizontally and takes with the second goods transport, and the direction in two goods transport areas is unanimous with the goods conveyer belt, is equipped with vertical rotating barrier between two goods transport areas, and rotating barrier is by the first motor drive who locates the automobile body bottom.

Furthermore, the fork is provided with a horizontal rotating shaft, the bottom of the truck body is provided with a second motor, the output shaft of the second motor and the horizontal rotating shaft are respectively provided with a chain wheel, and a chain which is meshed with each other is sleeved between the two chain wheels to form matching.

The goods fork has the advantages that goods are turned and forked by the goods fork, and then the goods are conveyed onto the bearing platform through the matching of the goods conveying belt, the rotating baffle plate, the first goods conveying belt and the second goods conveying belt, so that the self-loading and the self-unloading of the goods are realized, the goods are more conveniently loaded, and the goods are not required to be loaded and unloaded manually, so that the working efficiency is improved; the goods baffle can prevent that the goods from transporting the in-process and dropping, prevents that the goods from damaging.

Detailed Description

Referring to fig. 1 and 2, the present invention provides an AGV cart for automatically loading and unloading goods, which includes a cart body 1, a front wheel 2 and a rear wheel 3 are arranged at the bottom of the cart body 1, a bearing platform 4 is arranged at the top of the cart body 1, a downward slope 4a is arranged at one side of the bearing platform 4, which is located at the front wheel 2, and a semicircular goods baffle 5 is arranged at one side of the bearing platform 4, which is located at the rear wheel; the slope 4a is provided with a goods conveyor belt 6, the outer end of the slope 4a is provided with a fork 7, and the fork 7 can be turned upwards. Bearing platform still is equipped with first cargo transport area 8 of horizontally and second cargo transport area 9 at the interval, and first cargo transport area 8 is located the left and right sides respectively with second cargo transport area 9, and the direction in two cargo transport areas is unanimous with cargo conveyor belt 6, combines to show in fig. 3, is equipped with vertical rotating baffle 10 between two cargo transport areas, and rotating baffle 10 is driven by the first motor 11 of locating the automobile body bottom, through drive shaft 12 hub connection between first motor 11 and the rotating baffle 10.

As shown in fig. 4, the fork 7 is provided with a horizontal rotating shaft 13, the bottom of the truck body is provided with a second motor 14, an output shaft of the second motor 14 and the horizontal rotating shaft 13 are respectively provided with a first chain wheel 15 and a second chain wheel 16, and a chain 17 engaged with each other is sleeved between the two chain wheels to form a fit.

Referring to fig. 5, taking the first cargo transporting belt 8 as an example, the first cargo transporting belt includes a third motor 18 horizontally disposed at the bottom of the vehicle body and a set of transporting rollers 19, the third motor 18 and the transporting rollers 19 are connected at the same side end thereof respectively with a belt pulley 20, a belt 21 forming a transmission fit is sleeved on the outer periphery of the belt pulley 20, and a transporting belt 22 is sleeved on the outer periphery of the transporting rollers 19.

When in use, the method can be carried out according to the following steps:

when the goods are loaded, the goods are firstly forked by the fork 7, the second motor 14 is started and then drives the horizontal rotating shaft 13 to rotate through chain wheel transmission, and the fork 7 is turned upwards to enable the goods to fall on the goods conveying belt 6 of the slope 4 a; the goods conveyor belt 6 transports the goods upwards towards the bearing platform; meanwhile, the first motor 11 is started, the rotary baffle 10 starts to rotate, and the goods are shifted onto the bearing platform in an auxiliary mode; the cargo transport belt is started to transport the cargo to the inner side of the bearing platform. Then the AGV dolly can begin the transportation, and during the transportation, goods baffle 5 can prevent that the goods from transporting the in-process and dropping, prevents that the goods from damaging. When the goods are unloaded, the process is opposite to the loading, and the detailed description is omitted here.
