In order to obtain the information of the cargo quantity in the cargo storage 5, a pressure sensor for measuring the weight of the cargo may be provided inside the pallet 6. Wherein the pressure sensor may be connected to a control unit, which may comprise a microprocessor.

The weight of the goods can be measured by the pressure sensor, and the number of the goods on the pallet 6 can be determined.

When the goods are replenished, when the weight of the goods on the supporting plate 6 measured by the pressure sensor exceeds a first preset value, the control unit can control the reminding device to generate optical signals or/and sound signals so as to remind workers, and therefore the normal operation of the unattended intelligent equipment is prevented from being influenced due to the overlarge weight of the goods on the supporting plate 6.

when the unattended intelligent equipment is in the vending process and the weight of goods on the supporting plate 6 measured by the pressure sensor is smaller than the second preset value, the control unit can send replenishment information to the terminal through the wireless communication module. Wherein, the wireless communication module can be one or more of a GPRS module, a 3G module, a 4G module, a 5G module, a wifi module and the like.

On traditional vending machine, goods need the regular placing in corresponding goods way, and this just leads to need consuming a large amount of time when carrying out the restocking for the restocking efficiency is very low.

in this embodiment, however, the goods can be placed on the pallet 6 in disorder. When replenishing goods such as 3D glasses, facial mask, the staff can once only directly empty into storage storehouse 5 with many goods in, and the replenishment efficiency is very high, can use manpower sparingly effectively to can greatly reduce the cost of unmanned on duty smart machine operation and maintenance from this.

when the goods with soft packages are poured into the storage bin 5, part of the goods may be in a vertical state and lean against the inner wall of the storage bin 5, and the manipulator has certain difficulty in taking the part of the goods.

In order to solve the above problem, in this embodiment, the bottom of the supporting plate 6 may be provided with a vibration motor, and the supporting plate 6 may be driven to vibrate by the vibration motor, so that the goods in a vertical state may lie down.

Wherein, the top of support frame can be provided with elastic support spare, and the support frame passes through elastic support spare to support layer board 6. The elastic support member can be an elastic sheet or a spring, and the size and the elastic modulus of the elastic support member are controlled within a certain range, so that the overlarge vibration amplitude of the supporting plate 6 after the vibration motor is started is avoided.

In use, the lifting driving device 7 can drive the supporting plate 6 to reciprocate up and down, so that the supporting plate 6 can generate certain vibration.

In this embodiment, in order to facilitate the picking mechanism 3 to pick up the goods on the supporting plate 6, a visual positioning device 12 for identifying the position of the goods can be arranged right above the supporting plate 6, and the visual positioning device 12 can be mounted on the shell of the unattended intelligent device through a rotating arm or a telescopic arm and other structures. Wherein the visual positioning device 12 may comprise a camera.

The goods on the pallet 6 are photographed by the camera, and then the control unit sends a control signal to the displacement driving device 21 according to the photographed image information, thereby controlling the pickup mechanism 3 to more accurately pick up the goods. After the goods are picked up by the picking mechanism 3, the goods are transferred to the buffer mechanism 2.

As shown in fig. 3, in the present embodiment, the buffer mechanism 2 includes a box 13, a buffer chamber is disposed in the box 13, a partition 14 is disposed in the buffer chamber, and the partition 14 divides the buffer chamber into a first buffer area 15 and a second buffer area 16. The bottom of the box body 13 is provided with a switch device 17, and the switch device 17 is used for controlling the opening or closing of the goods outlet at the bottom of the first buffer area 15 and the second buffer area 16.

goods in the goods storage bin 5 are transferred to the first buffer area 15 and the second buffer area 16 in advance, after a user finishes purchasing, the switch device 17 is used for opening the goods outlet of the first buffer area 15 or/and the second buffer area 16, so that the goods fall into the goods receiving area, and the goods discharging work can be finished.

In case the volume of the partition 14 is neglected, the sum of the volumes of the first buffer area 15 and the second buffer area 16 equals the volume of the buffer chamber.

in fig. 4, the partition 14 is vertically disposed, and the capacities of both the first buffer area 15 and the second buffer area 16 may be the same. In use, both the first buffer 15 and the second buffer 16 may be pre-loaded with a good.

The capacities of the first buffer 15 and the second buffer 16 may be different to meet the purchase demands of different users. For example, the capacity of the first buffer 15 is larger than that of the second buffer 16, in which case the first buffer 15 may store two goods in advance and the second buffer 16 stores one goods in advance. When a user needs to purchase a good, the switch device 17 is used for opening the goods outlet of the second cache area 16; when a user purchases two goods, the switch device 17 is used for opening the goods outlet of the first cache region 15; when the user is purchasing three goods, the switch device 17 can sequentially open the outlets of the first buffer area 15 and the second buffer area 16.

As shown in fig. 1, a funnel-shaped goods receiving device 4 may be disposed right below the buffer mechanism 2, and after the goods outlet at the bottom of the first buffer area 15 or the second buffer area 16 is opened, the goods may drop into the goods receiving device 4 under the action of gravity, thereby facilitating the user to take the purchased goods away.

In the present embodiment, the switching device 17 may include a first switching section 18 and a second switching section 19. The first switch portion 18 is used to open or close the output port at the bottom of the first buffer area 15, and the second switch portion 19 is used to open or close the output port at the bottom of the second buffer area 16.

The first switch part 18 and the second switch part 19 both comprise a turnover plate and a turnover driving motor for driving the turnover plate to rotate, and the turnover plate is rotatably connected with the box body 13. In fig. 3, the tumble drive motor is not shown.

the first switching unit 18 and the second switching unit 19 are independent of each other and do not affect each other.

Goods in the goods storage bin 5 are moved to the position right above the first buffer area 15 or the second buffer area 16 through the picking mechanism 3, then the picking mechanism 3 loosens the goods, and the goods can fall into the first buffer area 15 or the second buffer area 16 under the action of gravity.

For the convenience of introduction, the box body 13 may be provided with an introduction slot, wherein after the goods are released by the picking mechanism 3, the goods fall into the introduction slot, and then the goods slide into the first buffer area 15 or the second buffer area 16 through the introduction slot under the action of gravity.

in this embodiment, the partition 14 is rotatably connected to the case 13. Since the partition 14 divides the buffer chamber into the first buffer area 15 and the second buffer area 16, the volumes of both the first buffer area 15 and the second buffer area 16 can be changed accordingly by rotating the partition 14.

when the capacity of the first buffer 15 increases, the capacity of the second buffer 16 decreases; when the capacity of the first buffer 15 is decreased, the capacity of the second buffer 16 is increased. Meanwhile, as the partition 14 rotates, the sizes of the cargo inlets of the first buffer area 15 and the second buffer area 16 are changed accordingly.

referring to fig. 4, the partition 14 is in a vertical state, in which the cross-sectional area of the first buffer area 15 is the same from top to bottom and the second buffer area 16 is the same; referring to fig. 5, the partition 14 is rotated to the left side such that the top of the partition 14 is in contact with the left inner wall of the container body 13, and at this time, the cargo inlet of the second buffer area 16 is in the maximum state, thereby facilitating the introduction of the cargo into the second buffer area 16.

Accordingly, when the partition 14 is rotated to the right, the top of the partition 14 can be in contact with the right inner wall of the case 13. When the top of the partition 14 is in contact with the right inner wall of the container body 13, the cargo inlet of the first buffer area 15 is in the maximum state, thereby facilitating the introduction of the cargo into the first buffer area 15.

It should be noted that, in order to make the top of the partition 14 contact with the left and right inner walls of the box 13, the size of the partition 14 and the box 13 should be controlled reasonably.

since the partition 14 can rotate, when goods are introduced into the first buffer area 15 and the second buffer area 16, the partition 14 needs to be controlled to rotate to the corresponding position.

As shown in fig. 6 and 7, in the present embodiment, the picking mechanism 3 includes a goods taking device 20 for picking up the goods in the goods storage mechanism 1 and a displacement driving device 21 for driving the goods taking device 20 to move above the buffer mechanism 2, wherein a detecting device 22 for detecting whether the goods taking device 20 contacts the goods is arranged on the goods taking device 20.

in the unattended intelligent apparatus, the goods taking device 20 is always located above the goods in the storage bin 5.

When the goods are cached, the goods taking device 20 is driven to move to the position of the goods by the displacement driving device 21; then, the goods are picked up by the goods taking device 20; then, the goods taking device 20 is driven by the displacement driving device 21, so that the goods move out of the goods storage bin 5 and move to the position right above the box body 13; finally, the goods are released by the goods taking device 20, and the goods automatically fall into the first buffer area 15 or the second buffer area 16, so that the goods buffer storage work is completed. Under the action of the detection device 22, whether the goods are contacted by the goods taking device 20 or not can be detected, so that the goods can be accurately picked up by the goods taking device 20, and invalid operation is avoided.

as shown in fig. 7 and 8, in the present embodiment, the pickup device 20 includes a vacuum pump 23 and a suction nozzle 24 connected to the vacuum pump 23, wherein the vacuum pump 23 is used for extracting air inside the suction nozzle 24.

In other embodiments, the pickup device 20 may also employ electric jaws, pneumatic jaws, or the like.

The vacuum pump 23 is used to pump the air inside the suction nozzle 24, so that the inside of the suction nozzle 24 generates negative pressure, and the goods contacting with the suction end of the suction nozzle 24 is sucked by the suction nozzle 24 under the action of atmospheric pressure. Wherein the suction end of the suction nozzle 24 is located at the front end of the suction nozzle 24, and in fig. 8, the suction end of the suction nozzle 24 is directed vertically downward.

After the goods move to the right above the shipment area, the air pressure inside the suction nozzle 24 returns to normal by controlling the vacuum pump 23, and at this time, the goods automatically fall into the shipment area due to self weight.

The suction nozzle 24 is well suited for picking up soft packaged goods, including bagged french fries, 3D glasses, facial masks, and the like. The soft package has the advantages of soft quality, smooth surface and the like, so the suction nozzle 24 can easily suck the soft package.

it should be noted that in this embodiment, the weight of the single piece of goods may not exceed the maximum suction force that can be generated by the suction nozzle 24. Generally, the mass of the single piece of goods is preferably more than 500 g.

In the present embodiment, the vacuum pump 23 is communicated with the suction nozzle 24 through a connection pipe 26, wherein an air pressure sensor 25 for detecting the air pressure inside the connection pipe 26 is provided on the connection pipe 26.

The connection pipe 26 may use a steel pipe. The steel pipe has a certain strength and is not easily deformed, so the vacuum pump 23 may be directly fixed to one end of the steel pipe. Wherein the other end of the connecting pipe 26 is in sealed communication with the sleeve at the tail end of the suction nozzle 24.

Before the goods are not touched, the vacuum pump 23 draws the air inside the suction nozzle 24, and the air pressure inside the connection pipe 26 is regarded as P1; when the suction nozzle 24 sucks the goods, the air pressure in the connection pipe 26 changes accordingly, and at this time, the air pressure in the connection pipe 26 can be regarded as P2; if the adsorbed cargo falls, the pressure inside the connecting pipe 26 changes accordingly, and the pressure inside the connecting pipe 26 can be regarded as P3.

The control unit can compare the positions P1, P2 and P3, so as to determine whether the suction nozzle 24 sucks the goods and whether the goods fall.

In order to enhance the absorption effect and stability, the suction nozzle 24 may be made of a material having elasticity, for example, the suction nozzle 24 may be made of a material such as silicon rubber or rubber. The suction nozzle 24 may be provided in a screw tubular shape, thereby allowing the suction nozzle 24 to be extended and contracted for better suction.

Because the suction nozzle 24 has elasticity, the suction nozzle 24 can better fit on the surface of the goods and adapt to the surface shape of the goods when the suction nozzle 24 performs suction work.

in this embodiment, a base 27 is provided at the rear of the suction nozzle 24, and an elastic member 28 for restoring and cushioning the suction nozzle 24 is provided on the base 27. The elastic member 28 may be a spring, wherein the spring is mounted on the base 27 and sleeved on a sleeve at the tail end of the suction nozzle 24.

In the process of picking up the goods by the suction nozzle 24, the suction nozzle 24 needs to generate a certain amount of extrusion on the goods under the action of the displacement driving device 21 so as to enable the suction end of the suction nozzle 24 to be in full contact with the goods. When the suction nozzle 24 is pressed, the suction nozzle 24 is deformed, and a portion of the suction nozzle 24 may be pressed into the base 27; when the suction nozzle 24 finishes the shipment operation, the suction nozzle 24 can be restored to the original state under the action of the spring, thereby facilitating the subsequent picking-up work of the suction nozzle 24.

The suction nozzle 24 generates a certain vibration during operation by the vacuum pump 23 and the displacement drive device 21. The use of springs may serve to cushion and thereby reduce the effect of vibrations on the suction nozzle 24.

In the present embodiment, the displacement drive device 21 includes an elevating mechanism 29, a first linear drive mechanism 30, and a second linear drive mechanism 31.

The lifting mechanism 29 is used for driving the goods taking device 20 to lift in the vertical direction; a first linear driving mechanism 30 for driving the elevating mechanism 29 to perform a linear motion in a direction parallel to the X-axis; and a second linear driving mechanism 31 for driving the first linear driving mechanism 30 to perform a linear motion in a direction parallel to the Y-axis.

Wherein the X-axis and the Y-axis are perpendicular and both are perpendicular to the plumb line.

In the present embodiment, the lifting mechanism 29 includes a parallelogram mechanism. The parallelogram mechanism is composed of connecting rods which are sequentially and rotatably connected end to end, and has the advantages of simple structure, small occupied space and the like.

As shown in fig. 7, the parallelogram mechanism includes a first link 32, a second link 33, a third link 34, and a fourth link 35. The first connecting rod 32 and the second connecting rod 33 are vertically arranged, the third connecting rod 34 and the fourth connecting rod 35 are arranged in parallel, two ends of the third connecting rod 34 are respectively connected with the tops of the first connecting rod 32 and the second connecting rod 33 in a rotating mode, and two ends of the fourth connecting rod 35 are respectively connected with the bottoms of the first connecting rod 32 and the second connecting rod 33 in a rotating mode. Wherein the goods taking device 20 is fixedly connected with the first connecting rod 32.

In this embodiment, the base 27 of the suction nozzle 24 may be secured to the first link 32 by an L-shaped connecting plate 36.

The second link 33 may be fixed to a bracket 37, the bracket 37 may be provided with a rotation driving motor,

One end of the third connecting rod 34 close to the second connecting rod can be fixedly provided with a rotating shaft, and the rotation driving motor can be in transmission connection with the rotating shaft through a gear reduction box. Under the action of the rotation driving motor, the third link 34 rotates, which in turn drives the second link 33 to rotate, thereby realizing the lifting of the goods taking device 20. Wherein, the rotation driving motor can adopt a stepping motor.
