[0002] With the increasing material and cultural needs of the people, there is a shopping demand at different time periods of a day, but there are very few businesses that can provide retail services at the early morning time period. Therefore, vending cabinets that can automatically sell goods have emerged as the times require, which can operate automatically for 24 hours without the need to be equipped with sales personnel, and in particular, vending cabinets that sell beverages are becoming more and more popular.

[0003] In the prior art vending cabinet, the height of the delivery hopper for receiving the output goods of the goods channel is usually matched with the highest goods to ensure that all goods will not roll out of the delivery hopper. However, since there is a certain distance between the goods channel and the delivery hopper on the delivery device, when the short bottle goods enter the delivery hopper from the goods channel, the short bottle goods are prone to have too large dumping angle and thus get stuck between the goods channel and the delivery hopper, resulting in failure to be normally output.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present application clearer, further detailed description will be given below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0030] In order to make the description of the present disclosure more detailed and complete, the following describes the embodiments and specific examples of the present application; but this is not the only form of implementation or use of the specific embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] It should be noted that the terms "first", "second", and the like in the description and claims of the application and the above drawings are used only to distinguish similar objects and do not necessarily have to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein.

[0032] In addition, in the description of the embodiments of the application, "a plurality of" means two or more than two, and other quantifiers similar thereto should be understood that the preferred embodiments described herein are only used to illustrate and explain the application, and are not used to limit the application, and the embodiments of the application and the features in the embodiments can be combined with each other without conflict.

[0033] As shown in Figure 1 and Figure 2 are the perspective views of the vending machine 100 equipped with the delivery device 200 provided by the embodiments of the application in different directions. As shown in Figure 3 and Figure 4 are the perspective views of the delivery hopper in different directions provided by the embodiments of the application, as shown in Figure 5 and Figure 6 are the partial perspective views of the delivery hopper in different directions provided by the embodiments of the application, as shown in Figure 8 and Figure 9 are the schematic views of the delivery device in the delivery state provided by the embodiments of the application. As shown in Figures 1 to 7 the delivery device 200 comprises a goods channel 210 and a delivery hopper 290, the delivery hopper 290 further comprises a guide flap 220, a first driving part 230 and a second driving part 240, and the lower end of the goods channel 210 is provided with a delivery trigger 23215.

[0034] The aisle 210 is used for transporting goods. Therefore, it can be understood that the aisle 210 is located inside the vending machine 100, and its number can be set according to the specific capacity of the vending machine 100. For example, the larger the capacity of the vending machine 100, the more aisles 210 can be set, and the smaller the capacity of the vending machine 100, the fewer aisles 210 can be set. Specifically, the length, width, and height of the aisle 210 can be set according to the size of the stored goods and the size of the vending machine 100. For example, the length of the aisle 210 can match the depth of the vending machine, the width of the aisle 210 can match the maximum width of the goods to be sold in the vending machine 100, and the height of the aisle 210 can match the height of the tallest item sold in the vending machine 100. More specifically, the cargo channel 210 is inclined. When the front row of goods in the cargo channel 210 is output from the outlet of the cargo channel 210, the rear row of goods in the cargo channel 210 will move towards the outlet of the cargo channel 210 until they are replenished to the position near the outlet of the cargo channel 210.

[0035] Among them, such as Figure 9 The guide flap 220 can rotate around a first preset axis to the outlet of the cargo channel 210 to guide the goods out of the cargo channel 210. Specifically, as shown... Figure 3 The two ends of the guide flap 220 are rotatably connected to the main body 250 of the discharge hopper 290 via pins, with the first preset axis being the direction of the line connecting the two pins. In the non-discharging state, the guide flap 220 is retracted, i.e., the free end faces upwards; in the discharging state, the guide flap 220 rotates clockwise to an inclined or horizontal position, with the free end close to the discharge port of the cargo channel 210. Goods in the cargo channel 210 are discharged from the discharge port and then guided by the guide flap 220 into the discharge hopper 290.

[0036] Among them, such as Figure 5 The first driving unit 230 includes a linkage mechanism 231 and a slide rail mechanism 232. The first end and the second end of the linkage mechanism 231 are respectively connected to the slide rail mechanism 232 and the guide flap 220. The slide rail mechanism 232 can drive the first end to move along a second preset direction, thereby driving the second end to drive the guide flap 220 to rotate. The second driving unit 240 can rotate unidirectionally around a third preset axis, so that the driving working section during the rotation process pushes the slide rail mechanism 232 to move along the second preset direction.

[0037] Specifically, Figure 5The Y-axis direction of the coordinate system shown in the figure is the second preset direction. In the present application, the second preset direction is perpendicular to the first preset direction. In this way, by rotating the second driving part 240, the slide rail mechanism 232 in the first driving part 230 is driven to move in the second preset direction, and then the first end of the connecting rod mechanism 231 connected with the slide rail mechanism 232 is driven to move in the second preset direction, so that the second end of the connecting rod mechanism 231 is driven to displace, and the guide flap 220 connected with the second end is driven to rotate. Specifically, the second end generates a displacement component in the horizontal direction of the goods channel, so as to push the guide flap 220 to flip towards the goods channel. Therefore, the arrangement of the first driving part 230 and the second driving part 240 enables the final rotation of the guide flap 220 by the initial rotation of the second driving part 240.

[0038] It can be understood that, since the second driving part 240 performs a rotating motion, its trajectory is a circle, so that when it pushes the slide rail mechanism 232 to move, it is essentially that the slide rail mechanism 232 is pushed to move by the contact between points. It should be noted that, in the process of dispensing a single piece of goods in the vending cabinet 100, the second driving part 240 rotates in one direction for one circle, and in the process of rotating in one direction for one circle, it does not push the slide rail mechanism 232 all the time, but only pushes the slide rail mechanism 232 in the driving working section. Specifically, when a single piece of goods is dispensed, the second driving part 240 rotates under the driving of the motor, contacts the slide rail mechanism 232 at the first phase, continues to rotate, pushes the slide rail mechanism 232 to move, and is separated from the slide rail mechanism 232 at the second phase. Therefore, the process of rotating the second driving part 240 from the first phase to the second phase is referred to as the driving working section. When the driving working section ends, the second driving part 240 is separated from the slide rail mechanism 232, the second driving part 240 stops pushing the slide rail mechanism 232, and the guide flap 220 also stops rotating, so that the guide flap 220 does not continue to rotate after reaching the dispensing opening of the goods channel 210.

[0039] The vending device provided by the present application forms a guide slope by rotating the guide flap 220 to the dispensing opening of the goods channel 210 during dispensing, so as to guide the goods to smoothly slide from the goods channel 210 to the dispensing hopper, greatly reduces the probability of goods being stuck, and especially solves the technical problem that shorter goods are easily stuck between the goods channel 210 and the dispensing hopper 290. Moreover, compared with vertical falling, the sliding output of the goods to the dispensing hopper 290 through the guide flap 220 can effectively slow down the falling speed and impact force of the goods, so as to avoid deformation or damage of the goods during dispensing.

[0040] Comparison Figure 8 and Figure 9 , Figure 8The outfeed device is not provided with a guide flap, and when goods are outfeed, the goods directly fall from the outfeed port of the goods channel to the outfeed hopper. For short bottle goods, the dumping angle is large, and the goods are easy to be stuck between the goods channel and the outfeed hopper. Figure 9 In the embodiment, the outfeed device is provided with a guide flap, the guide flap guides the goods to slide from the goods channel to the outfeed hopper, and the dumping angle of the goods is small, so that the goods are not easy to be stuck.

[0041] In the vending cabinet 100 of the present application, as shown in Figure 2 , an X-axis movement track 120 and a Z-axis movement track 130 are further provided, and the outfeed hopper 290 can move along the X-axis movement track 120 and the Z-axis movement track 130 to receive the goods in the corresponding goods channel 210 and deliver the goods to the cabinet outfeed conveying port 110. Figure 2 In the XYZ three-dimensional coordinate system shown in , the Y-axis direction is the second preset direction. The Y-axis direction coincides with the extension direction of the goods channel 210.

[0042] Figure 3 As shown in Figure 4 , the outfeed hopper 290 comprises a main body 250, the main body 250 further comprises a first side wall 251, a second side wall 252, a third side wall 253, a fourth side wall 254, a fifth side wall 255, a sixth side wall 256 and a goods placing table 257, the first driving part 230 is connected to the first side wall 251, the fourth side wall 254 is used for shielding the first driving part 230, the fourth side wall 254 is spaced apart from and parallel to the first side wall 251, the second side wall 252 is spaced apart from and parallel to the third side wall 253, the first side wall 251 is vertically connected to the second side wall 252 and the third side wall 253, and the fourth side wall 254 is also vertically connected to the second side wall 252 and the third side wall 253; the fifth side wall 255 is spaced apart from and parallel to the fourth side wall 254, the sixth side wall 256 is vertically connected to the fourth side wall 254 and the fifth side wall 255, and the sixth side wall 256 is opposite to the guide flap 220, wherein the fourth side wall 254, the fifth side wall 255, the sixth side wall 256 and the goods placing table 257 form a containing cavity for containing the goods falling from the goods channel 210. Preferably, the fourth side wall 254, the fifth side wall 255 and the sixth side wall 256 are integrally formed. Since the goods sold by the vending cabinet 100 include high goods and low goods, in order to prevent the high goods from falling out of the outfeed hopper 290, a detachable baffle 291 can be installed on the sixth side wall 256 of the outfeed hopper 290, so that the height of the baffle 291 can be adjusted according to the height of the goods, so that the goods will not fall out of the outfeed hopper 290.

[0043] As shown in Figure 5 and Figure 6As shown, the connecting rod mechanism 231 comprises a first connecting rod 2311 and a second connecting rod 2312. The first connecting rod 2311 has the first end portion, and the second connecting rod 2312 has a second end portion. The other end portion of the first connecting rod 2311 and the other end portion of the second connecting rod 2312 are rotationally connected by a first pin shaft 2313. The first pin shaft 2313 is further sleeved with a first torsional spring. The opposite sides of the first connecting rod 2311 and the second connecting rod 2312 are respectively provided with a first clamping hole 23111 and a second clamping hole 23121, and the two torsional arms of the first torsional spring are respectively clamped in the first clamping hole 23111 and the second clamping hole 23121.

[0044] It can be understood that the slide rail mechanism 232 performs a linear motion, and the guide flap 220 performs a flipping motion. Therefore, the connecting rod mechanism 231 is used to convert the linear motion into the flipping motion. Specifically, the connecting rod mechanism 231 of the present application adopts a double connecting rod. The first end portion is arranged at one end of the first connecting rod 2311, and the second end portion is arranged at one end of the second connecting rod 2312. The two connecting rods are rotationally connected by the first pin shaft 2313. The first torsional spring (not shown in the figure) is sleeved at one end of the first pin shaft 2313 close to the first side wall 251. That is, the first connecting rod 2311 is connected with the slide rail mechanism 232, the second connecting rod 2312 is connected with the guide flap 220, and the first connecting rod 2311 and the second connecting rod 2312 are clamped with the first torsional spring. Therefore, after the guide flap 220 is in place, the excess driving stroke can be offset by folding the double connecting rod. The arrangement of the first torsional spring also enables the first connecting rod 2311 and the second connecting rod 2312 to return to the initial state after the second driving portion 240 pushes the slide rail mechanism 232 to end. In other words, the connecting rod mechanism 231 arranged in the form of a double connecting rod realizes the one-way decoupling of the functions of the slide rail mechanism 232 and the guide flap 220, ensures that the slide rail mechanism 232 can drive the guide flap 220 to flip when it is pushed out, and the angle of the guide flap 220 does not affect the stroke of the slide rail mechanism 232. In this way, the double connecting rod with the torsional spring in the above embodiment is used to drive the guide flap 220, which can ensure that the guide flap 220 can offset the excess stroke by folding the connecting rod after it is in place.

[0045] In the above embodiment, the two torsional arms of the first torsional spring are respectively clamped in the first clamping hole 23111 and the second clamping hole 23121, and the first clamping hole 23111 and the second clamping hole 23121 are respectively arranged on the opposite sides of the first connecting rod 2311 and the second connecting rod 2312. In this way, when the first connecting rod 2311 and the second connecting rod 2312 are relatively rotated by the first pin shaft 2313, the rotation angle of the first connecting rod 2311 and the second connecting rod 2312 can be limited by being clamped in the first torsional spring, so that the first connecting rod 2311 and the second connecting rod 2312 are rotated within the required angle range, and the state recovery is facilitated.

[0046] In an alternative implementation, as shown inFigure 5 , Figure 6 and Figure 10 As shown, the dispensing hopper 290 also includes a main body 250. A guide rail 280 is provided on the first side wall 251 of the main body 250. The guide rail 280 extends along the second preset direction. The slide rail mechanism 232 includes a slider 2322 and a pusher 2321. The slider 2322 is slidably connected to the guide rail 280. The pusher 2321 is fixedly connected to the slider 2322. The pusher 2321 further includes a first push rod 23211. The extension direction of the first push rod 23211 is perpendicular to the second preset direction. The second driving part 240 pushes the first push rod 23211 in the driving working section.

[0047] Specifically, a guide rail 280 is mounted on the first sidewall 251 of the main body 250. The guide rail 280 extends along a second preset direction, and its extension direction coincides with the width direction of the first sidewall 251, so as to fit snugly against the first sidewall 251. The extension direction of the first push rod 23211 is perpendicular to the second preset direction. In other words, the extension direction of the first push rod 23211 is perpendicular to the extension direction of the guide rail 280. The distance between the free end of the first push rod 23211 and the rotation axis of the second drive unit 240 is less than the rotation radius of the second drive unit 240. Therefore, during the rotation of the second drive unit 240, the distal end of the second drive unit 240 comes into contact with the first push rod 23211. Thus, during the shipment of a single item, the second drive unit 240 pushes against the first push rod 23211 in the drive working section. The drive working section can be adjusted by adjusting the extension length of the first push rod 23211 and the rotation radius of the second drive unit 240. Understandably, due to the limiting effect of the guide rail 280, the first push rod 23211, under the pushing of the second drive unit 240, drives the slider 2322 to move along the guide rail 280 toward the cargo channel 210. The slider 2322 drives the first connecting rod 2311 to move, and the first connecting rod 2311 drives the end of the second connecting rod 2312 to move, thereby driving the guide flap 220 to rotate toward the cargo channel 210.

[0048] like Figure 9 As shown, the shipping device 200 further includes a shipping trigger 23215, which is disposed at the shipping port; as Figure 5 , Figure 6 , Figure 10 and Figure 11As shown, the pushing member 2321 further comprises a fixed base 23214, a second pushing rod 23212, the fixed base 23214, the first pushing rod 23211 and the second pushing rod 23212 are integrally arranged, the fixed base 23214 is fixedly connected with the sliding block 2322, the second pushing rod 23212 is arranged at one end of the fixed base 23214 close to the goods channel 210, and an extension direction of the second pushing rod 23212 is parallel to the first pushing rod 23211; wherein when the second driving part 240 pushes the first pushing rod 23211, the fixed base 23214 drives the sliding block 2322 to move along the guide rail 280, so that the second pushing rod 23212 pushes the goods release trigger 23215 to control the goods channel 210 to release goods.

[0049] Specifically, in the present embodiment, the pushing member 2321 integrally integrates the fixed base 23214, the first pushing rod 23211 and the second pushing rod 23212, the fixed base 23214 has a threaded hole, and a screw can be used to pass through the threaded hole to realize fixed connection of the pushing member 2321 and the sliding block 2322. In order to make the second pushing rod 23212 push the goods release trigger 23215 when the first pushing rod 23211 moves along the second preset direction, the second pushing rod 23212 is arranged at one end of the fixed base 23214 close to the goods channel 210 in the second preset direction. In order to avoid that the goods release trigger 23215 affects normal release of goods, the goods release trigger 23215 can be arranged below the goods channel 210. In the release process, the second driving part 240 rotates one circle in one direction, and in the driving working section, the first pushing rod 23211 is pushed, and the second pushing rod 23212 integrated with the first pushing rod 23211 is driven by the fixed base 23214 to move along the guide rail 280 to the goods channel 210 side to push the goods release trigger 23215, so that the goods release trigger 23215 is displaced to the inside of the goods channel 210, drives the connected goods release half leaf to open, and realizes release of goods. Because the goods channel is inclined, the goods in the goods channel pass through the opened half leaf channel and fall into the release hopper 290. Wherein the pushing member 2321 uses the first pushing rod 23211 to move to realize that the guide flap 220 is rotated to the release port, and simultaneously uses synchronous movement of the second pushing rod 23212 to push the goods release trigger 23215 to control the goods channel 210 to release goods, and ingeniously realizes release of goods by using the jump plate.

[0050] In an alternative embodiment, as Figure 5 、 Figure 6 and Figure 11As shown, the pushing member 2321 further comprises a reinforcing member 23213, and the fixed base 23214 has an extension section connected to the second pushing rod 23212, and the reinforcing member 23213 is arranged in a receiving cavity on the extension section and the second pushing rod 23212 towards the second driving part 240; the delivery hopper 290 further comprises a tension spring 260, one end of the tension spring 260 is fixed to the second side wall 252 of the main body 250, and the other end is hooked to the reinforcing member 23213; wherein the second side wall 252 is connected perpendicularly to the first side wall 251.

[0051] Specifically, the reinforcing member 23213 is vertically bent, wherein the extension direction of the first section is the same as the second preset direction, and the extension direction of the second section is the same as the second pushing rod 23212. The fixed base 23214 has an extension section, and the second pushing rod 23212 is connected to one end of the extension section close to the goods channel 210, and the upper and lower ends of the extension section and the second pushing rod 23212 towards the second driving part 240 protrude with a blocking edge, thereby forming a receiving cavity, and the reinforcing member 23213 is arranged in the receiving cavity; the end of the reinforcing member 23213 close to the first pushing rod 23211 has a through hole for hooking the tension spring 260. One end of the tension spring 260 is fixed to the second side wall 252 of the main body 250 and remains stationary, and the other end of the tension spring 260 is hooked to the reinforcing member 23213. Therefore, during the delivery process, the other end of the tension spring 260 will be in a stretched state as the pushing member 2321 moves synchronously towards the goods channel; when the driving work section of the second driving part 240 ends, the second driving part 240 is separated from the first pushing rod 23211, and the pushing member 2321 loses the pushing force applied by the second driving part 240, so that the tension spring 260 returns to the initial state and pulls the reinforcing member 23213 to drive the pushing member 2321 to move along the guide rail 280 away from the goods channel 210, while synchronously moving the connecting rod mechanism 231 connected to the pushing member 2321, and the connecting rod mechanism 231 synchronously drives the guide flap 220 to reverse and flip, and in this process, if there is goods on the guide flap 220, the reverse and flip of the guide flap 220 can push the goods into the delivery hopper 290.

[0052] In an alternative implementation, as shown in Figure 5 , Figure 6 and Figure 7 , the second driving part 240 comprises a rotating base 241, an extension arm 242, and a cam follower 243; wherein the rotating base 241 is connected to the driving member 270, and the axis direction of the rotating base 241 is the third preset axis direction; one end of the extension arm 242 is connected to the rotating base 241; the cam follower 243 is arranged at the free end of the extension arm 242 to rotate unidirectionally around the third preset axis direction under the driving of the rotating base 241, and to push the first pushing rod 23211 during the driving work section in the rotating process.

[0053] Specifically, the driving member 270 has a power output shaft, and the rotating base 241 can be sleeved on the power output shaft to be driven to rotate. In the present embodiment, the elongated arm 242 has one end connected to the rotating base 241, and when the rotating base 241 rotates around the third preset axis, the elongated arm 242 also rotates around the third preset axis, and the third preset axis coincides with the geometric center line of the Z-direction limb of the rotating base 241. The elongated arm 242 is arranged such that when the second driving part 240 rotates around the third preset axis, the radius of rotation increases, thereby ensuring that the first push rod 23211 can be moved by a preset distance. In the present embodiment, the cam follower 243 is arranged at the free end of the elongated arm 242, and the cam follower 243 moves synchronously with the elongated arm 242, and can drive the first push rod 23211 to move along the guide rail during the driving operation. It can be understood that the cam follower 243 is cylindrical and has excellent bending and torsional stiffness, and can well withstand the torque generated by eccentric driving; the outer periphery of the cam follower 243 is arc-shaped, so that when the cam follower 243 abuts against the first push rod 23211, the damage to the first push rod 23211 is small, thereby ensuring the horizontal movement precision of the first push rod 23211.

[0054] In an alternative embodiment, as shown in Figure 6 and Figure 7 , the opposite sides of the rotating base 241 and the elongated arm 242 respectively extend the first connecting part 2411 and the second connecting part 2421, the second connecting part 2421 has a connecting interval for the first connecting part 2411 to extend into, and the first connecting part 2411 and the second connecting part 2421 are rotationally connected through the second pin shaft 245. The second pin shaft 245 is sleeved with the second torsional spring 244.

[0055] Specifically, the second driving part 240 also has a double connecting rod mechanism, that is, the first connecting part 2411 and the second connecting part 2421 form a double connecting rod driving mechanism to form a soft connection between the cam follower 243 and the rotating base 241; one end of the extension arm 242 is connected to the cam follower 243, and the other end has a through hole for inserting the second pin shaft 245, and of course the rotating base 241 is also provided with a through hole for inserting the second pin shaft 245 at the corresponding position in the up-down direction, and the first connecting part 2411 and the second connecting part 2421 are rotationally connected through the second pin shaft 245. The second torsion spring 244 is sleeved below the second pin shaft 245 and is clamped between the rotating base 241 and the extension arm 242. At the critical value of the end of the preset driving working section, under the driving of the driving part 270, the cam follower 243 pushes away the first push rod 23211 and continues to rotate clockwise to return to the initial position; when the cam follower 243 pushes the first push rod 23211 and wants to be separated from the first push rod 23211, the first connecting part 2411 and the second connecting part 2421 are relatively bent, and the torsion arm of the second torsion spring 244 is laterally extruded; after the cam follower 243 is separated from the first push rod 23211, the second torsion spring 244 drives the first connecting part 2411 and the second connecting part 2421 to return to the initial state. The driving part 270 in the application can be a worm gear motor, which cooperates with the second driving part 240 in the form of a double connecting rod structure to smoothly separate the cam follower 243 from the first push rod 23211.

[0056] In an alternative implementation, as shown in Figure 5 and Figure 6 The extension arm 242 also connects the position sensing sheet 246, and the bottom plate of the main body 250 is provided with a position sensor 247 for sensing the position sensing sheet 246; when the position sensing sheet 246 rotates to the first preset position synchronously with the extension arm 242, the position sensor 247 is triggered, and the driving part 270 stops working.

[0057] Specifically, the extension arm 242 connects one end of the cam follower 243, and also connects the position sensing sheet 246. The cam follower 243 is connected to the upper end of the extension arm 242, and the position sensing sheet 246 is connected to the side end of the extension arm 242. The sensing part of the position sensing sheet 246 is a horizontally extending flat plate. The first preset position can be the area directly above the in-place sensor 247, that is, the flat plate-shaped sensing part of the position sensing sheet 246 is rotated to the position directly above the in-place sensor 247, and is sensed by the in-place sensor 247. It can be understood that the position sensing sheet 246 can be synchronously rotated with the extension arm 242 around the third preset axis. When the position sensing sheet 246 is rotated to the position directly above the in-place sensor 247, the in-place sensor 247 is triggered. The controller of the present vending cabinet can control the driving member 270 to stop working based on the trigger signal of the in-place sensor 247. The triggering of the in-place sensor 247 indicates that the cam follower 243 on the extension arm 242 pushes the first push rod 23211 to drive the second push rod 23212 to move to the position of the delivery trigger 23215, and the goods channel 210 is releasing goods. Therefore, the driving member 270 stops working at this time, and the delivery device remains in a stable state. In a preferred embodiment, when the extension arm 242 is rotated to be parallel to the guide rail 280, the position sensing sheet 246 on the extension arm 242 is arranged to trigger the in-place sensor 247, so that the driving member 270 stops working. It can be understood that when the extension arm 242 is rotated to be parallel to the guide rail 280, the cam follower 243 has pushed the push member 2321 to translate in the second preset direction to the goods channel 210 by the maximum distance, and the second push rod 23212 achieves the maximum pushing distance of the delivery trigger 23215 in the second preset direction, thereby ensuring that the delivery passage is opened.

[0058] In an alternative implementation, as shown in Figure 5 The delivery hopper 290 further includes a flap angle adjusting member 221. The flap angle adjusting member 221 further includes an adjusting column 2211 and two limiting nuts 2212. An adjusting hole is arranged on one end of the guide flap 220 close to the connecting rod mechanism 231, and the adjusting column 2211 passes through the adjusting hole. The two limiting nuts 2212 are respectively screwed on the adjusting column 2211 and located on both sides of the adjusting hole. The limiting nuts 2212 are used to adjust the length of the adjusting column 2211 extending out of the adjusting hole. The adjusting column 2211 abuts against the third side wall 253 of the main body 250 at the end of the rotation of the guide flap 220, so as to limit the maximum rotation angle of the guide flap 220. The third side wall 253 is connected perpendicularly to the first side wall 251.

[0059] Specifically, the limiting nuts 2212 on both sides of the adjusting hole can adjust the length of the adjusting column 2211 extending out of the adjusting hole. Preferably, the limiting nut 2212 close to the third side wall 253 can be a press-in nut, and the other limiting nut 2212 can be a hexagonal nut. It can be understood that if the adjusting column 2211 extends out of the adjusting hole for a long length, that is, the adjusting column 2211 passes through the adjusting hole at the third side wall 253 end more, when the guide flap 220 is driven to rotate by the slide rail mechanism 232, it will abut against the third side wall 253 earlier, so that the guide flap 220 has a smaller rotation angle and a larger slope when lapping with the goods channel 210; if the adjusting column 2211 extends out of the adjusting hole for a short length, that is, the adjusting column 2211 passes through the adjusting hole at the third side wall 253 end less, when the guide flap 220 is driven to rotate by the slide rail mechanism 232, it will abut against the third side wall 253 later, so that the guide flap 220 has a larger rotation angle and a smaller slope when lapping with the goods channel. In this way, the maximum rotation angle of the guide flap 220 can be set according to different goods, so as to adjust the guide slope when the guide flap 220 discharges goods, to ensure smooth sliding of the goods and reduce the risk of goods jamming.

[0060] It can be understood that during the discharging process, the guide flap 220 needs to be rotated to the discharging port first, and then the second push rod 23212 pushes the discharging trigger 23215 to control the goods channel 210 to release the goods.

[0061] In the preferred embodiment as described above, when the extension arm 242 rotates to be parallel to the guide rail 280, the in-place sensor 247 is triggered and the driving motor stops working. It can be understood that when the extension arm 242 rotates to be parallel to the guide rail 280, the cam follower 243 cannot exert a pushing force on the pusher 2321 in the second preset direction, so that the guide flap 220 cannot continue to flip. If the guide flap 220 has not yet lapped with the discharging port of the goods channel 210 at this time, the goods cannot be successfully guided out of the discharging port of the goods channel 210. The length of the adjusting column 2211 extending out of the adjusting hole can be adjusted by the two limiting nuts 2212, so as to adjust the rotation angle of the guide flap 220, so as to lap with the discharging port. Therefore, at a certain time before the extension arm 242 rotates to be parallel to the extension direction of the guide rail 280, the second push rod 23212 does not contact the discharging trigger 23212, but the adjusting column 2211 has abutted against the third side wall 253, and the guide flap 220 has been rotated in place. Therefore, if the cam follower 243 cannot exert a pushing force on the pusher 2321 in the second preset direction, so that the guide flap 220 cannot continue to flip and cannot lap with the discharging port of the goods channel 210, the rotation angle of the guide flap 220 can be made larger by the action of the adjusting column 2211, to compensate for the rotation angle of the guide flap 220 that cannot be reached by the cam follower 243 to the discharging port.

[0062] That is, when the adjusting column 2211 abuts against the third side wall 253 of the main body 250, the extension arm 242 has not rotated to be parallel to the guide rail 280, and the driving member 270 is still working. As mentioned above, the connecting rod mechanism 231 includes the first connecting rod 2311 and the second connecting rod 2312, and one end of the first connecting rod 2311 and one end of the second connecting rod 2312 are rotationally connected through the first pin shaft 2313. When the adjusting column 2211 presses the main body 250, the first connecting rod 2311 and the second connecting rod 2312 will be bent, so that the pushing force applied by the pushing member 2321 to the guide flap 220 in the second preset direction is released to a certain extent, so that the adjusting column 2211 can be prevented from continuously pressing the third side wall 253 to damage the main body 250.

[0063] In an alternative implementation, as shown in Figures 3 to 7 The main body 250 further has a goods placing table 257 covering the second driving part 240, and the goods placing table 257 is provided with a goods detector. The bottom plate of the main body 250 is further provided with an original position sensor 248. After the adjusting column 2211 abuts against the third side wall 253, the driving member 270 continues to work for a preset time until the in-place sensor 247 is triggered to stop working, so that the goods channel 210 releases the goods. The goods fall on the goods placing table 257 to trigger the goods sensor, and the driving member 270 starts to work until the extension arm 242 rotates to a second preset position, the cam follower 243 is separated from the first push rod 23211 to return to the initial position, and the position sensing sheet 246 is sensed by the original position sensor 248 to trigger the driving member 270 to stop working. When the cam follower 243 is separated from the first push rod 23211, the tension spring 260 drives the pushing member 2321 to reset, and drives the guide flap 220 to rotate reversely to reset.

[0064] Specifically, the main body 250 further includes a fourth side wall 254 shielding the first driving part 230, and a goods placing table 257 shielding the second driving part 240 and used for placing goods. When there is no goods to be delivered, the extension arm 242 is in the initial position, and the cam follower 243 and the position sensing sheet 246 are also in the respective initial positions. In the initial position of the position sensing sheet 246, the position sensing sheet 246 is sensed by the original position sensor 248. When there is no goods to be delivered, the free end of the guide flap 220 is upwardly folded.

[0065] When the delivery device receives the delivery instruction, the driving member 270 starts to work. The driving member 270 drives the rotating base 241 to rotate unidirectionally around the third preset axis, which can be clockwise rotation. The rotating base 241 drives the cam follower 243 on the connected extension arm 242 to rotate. The cam follower 243 starts to push the slide rail mechanism 232 to move along the second preset direction at the driving working section, and approaches the goods channel 210. The tension spring 260 is stretched. The slide rail mechanism 232 drives the connecting rod mechanism 231 to move, and the connecting rod mechanism 231 drives the guide flap 220 to rotate clockwise. The free end of the guide flap 220 is turned to the side of the goods channel, and the connected adjusting column 2211 is also synchronously rotated. When the adjusting column 2211 abuts against the third side wall 253, the guide flap 220 stops rotating. However, the driving member 270 continues to work until the position sensing sheet 246 on the extension arm 242 triggers the position sensor 247 at the first preset position. The driving member 270 stops working. When the position sensor 247 is triggered, it indicates that the delivery trigger 23215 is pushed by the second push rod 23212, and the goods channel 210 is releasing goods. It can be understood that the second push rod 23212 can not contact the delivery trigger 23215 when the guide flap 220 stops rotating. With the continuous work of the driving member 270, the second push rod 23212 contacts the delivery trigger 23215 and applies a pushing force to the delivery trigger 23215 extending to the inside of the goods channel 210. Until the extension arm 242 is parallel to the guide rail direction, the position sensor 247 is triggered. The goods channel is opened under the action of the delivery trigger 23215 to release goods.

[0066] When the goods fall into the goods placing table 257 through the guide flap 220, the weight borne by the goods placing table 257 changes, the goods sensor is triggered, the delivery device controller sends a start signal to the driving member 270, the driving member starts to work, and continues to drive the rotating base 241 to rotate, driving the extension arm 242 to rotate from the parallel position to the second preset position. At this position, the cam follower 243 is separated from the first push rod 23211, and continues to rotate back to the initial position. The second preset position can be a position deviated by 5-8 degrees from the parallel position. When the extension arm 242 drives the cam follower 243 to return to the initial position, the position sensing sheet 246 on the extension arm 242 is sensed by the original position sensor 248. The delivery device controller receives the signal of the original position sensor 248, and controls the driving member 270 to stop working. After the cam follower 243 is separated from the first push rod 23211, the push member 2321 loses the pushing force in the second preset direction, and the tension spring 260 drives the push member 2321 to move reversely to reset. The connecting rod mechanism 231 is also reversely moved, and drives the guide flap 220 to rotate counterclockwise to reset. Thus, the delivery of a single piece of goods is completed.

[0067] It can be understood that the prior art delivery device utilizes a motor to drive the push rod to move, and the push rod pushes the delivery trigger of the goods channel to realize delivery, and the push rod returns by the motor drive, and cannot return quickly, so that after the previous goods is delivered, the next goods cannot be returned in time, so that the delivery trigger cannot rebound in time, thereby causing continuous delivery, and the goods can be stuck between the delivery hopper and the goods channel. When the second push rod 23212 pushes the delivery trigger 23215 to deliver, the second push rod 23212 is quickly pulled back to the original position by the force of the tension spring 260 when it is determined that the goods have been located on the goods placing table 257, so that the second push rod 23212 quickly separates from and is away from the delivery trigger 23215, and the corresponding delivery trigger 23215 can also quickly rebound to the original position, thereby solving the problems in the prior art. That is, the return of the delivery pusher in the present application is realized by the instantaneous release of the elastic potential energy of the elastic member, which can avoid the continuous delivery of the goods being stuck; and when the guiding flap 220 is reset by the reverse rotation of the return of the pusher, if the guiding flap 220 has goods, the goods on the guiding flap 220 can be pushed to the hopper, thereby avoiding the occurrence of the goods being stuck.

[0068] The above describes the technical solutions provided by the present application in detail, and the principles and implementation manners of the present application are described by applying specific examples; the above description of the examples is only used to help understand the structure of the present application and its core idea; meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation manners and application ranges can be changed, and the above description of the present application should not be understood as a limitation of the present application.

[0069] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies thereof, the present application also intends to include these modifications and variations.
