Description

Technical Field

[0001] The present invention relates to the technical field of annular suspension conveying, and more specifically, to an intelligent suspension conveying system for a milk box of a coffee machine. Background Art

[0002] The coffee machine milk box intelligent hanging and conveying system is an advanced system that combines automatic hanging technology, intelligent control and conveying devices. It is mainly used for automatic hanging and conveying management of milk boxes during the coffee making process of coffee machines. Its core function is to improve efficiency and reduce labor costs.

[0003] In the existing public documents, the patent announcement number CN217349433U discloses a coffee machine milk box conveying device, which drives the disc to rotate through the mounting rod, and then drives the mounting column to rotate through the disc. At the same time, due to the cooperation between the mounting column and the long mouth, the mounting column will drive the two baffles to move toward each other on the outer surface of the limit rod, and the two baffles will drive the pulley to contact the milk boxes, so that the operator can limit the milk box on the top of the conveyor belt to prevent it from falling, which brings convenience to the operator. However, this technology still has the following defects.

[0004] Although the intelligent hanging conveying system for milk cartons of coffee machines can realize automatic delivery of milk cartons to coffee machines, there is an efficiency bottleneck in the milk filling process. The current system needs to stop operating after the milk cartons are delivered to the coffee machine, and the milk cartons must be manually taken out and opened before the milk can be poured into the milk inlet of the coffee machine. This process cannot be completed without stopping the conveyor, resulting in operation interruptions and increased time consumption. Secondly, the conveying device needs to be frequently started and stopped, which not only reduces the overall conveying efficiency, but also affects the life of the equipment. Therefore, it is difficult to achieve accurate milk filling without stopping the milk carton conveyor of the coffee machine. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solutions: an intelligent hanging and conveying system for milk boxes of a coffee machine, comprising an annular conveying frame, a plurality of hanging frames and a wireless controller, wherein the plurality of hanging frames are fixed on the outer wall of the annular conveying frame, and a hanging follow-up conveying assembly is provided below the hanging frame; the hanging follow-up conveying assembly comprises a row of pipes arranged below the hanging frame, and the outer wall of the row of pipes is slidably connected with a sliding sleeve plate, the lower surface of the sliding sleeve plate is slidably connected with an arc-shaped collecting groove, the outer wall of the sliding sleeve plate is fixedly connected with a sliding sleeve strip, the inner wall of the sliding sleeve strip is slidably connected with an arc rail, and the outer wall of the sliding sleeve strip is slidably connected with an arc-shaped groove strip; a guide hole is provided at the bottom end of the inner wall of the hanging frame, and a plurality of row grooves are provided on the inner wall of the row of pipes.

[0006] Preferably, the arc rail is fixedly connected to the arc groove bar, and the arc groove bar is fixedly connected to the arc collecting groove; the inner wall of the guide hole is chamfered. A silicone ring is fixedly connected to the outer wall of the row pipe near the row groove; a pressure ring is fixedly connected to the lower surface of the silicone ring, and a positioning pressure sensor is installed on the lower surface of the pressure ring, and a micro-electric cylinder is installed on the lower surface of the positioning pressure sensor, the micro-electric cylinder is fixedly connected to the sliding sleeve, and the output end of the micro-electric cylinder is fixedly connected to the sensing end of the positioning pressure sensor; the micro-electric cylinder and the positioning pressure sensor are both electrically connected to the wireless controller; the lower surface of the arc collecting groove is fixedly connected to the coffee machine guide pipe.

[0007] When this technology is in use, the micro-electric cylinder pushes the positioning pressure sensor upward, and the pressure ring drives the silicone ring upward. At the same time, the silicone ring is squeezed and fits the lower surface of the hanging frame. When the pressure value sensed by the positioning pressure sensor is the same as the pressure value set by the wireless controller, the micro-electric cylinder is closed through the wireless controller. The pressure ring will also drive the discharge pipe upward, and the guide hole will be inserted into the position of the weak paper at the bottom of the milk box. The arc-shaped titanium-zinc plate will limit the upper surface of the milk box, and the discharge pipe will be connected to the milk box immediately. As the hanging frame continues to rotate and transport, the discharge pipe drives the sliding sleeve to rotate, and the sliding sleeve will also drive the sliding sleeve to move right in an arc path. The sliding sleeve moves right in an arc path along the outer wall of the arc track. In this way, when the milk box rotates, the milk can be transported into the discharge pipe, and the discharge pipe moves the milk to the lower row along the inside of the arc-shaped collection trough.

[0008] Preferably, a positioning block is provided on one side of the row pipe, and the positioning block is fixedly connected to the sliding sleeve. A distance sensor is fixedly installed on the upper surface of the arc-shaped collecting trough and away from the positioning block, and the distance sensor is electrically connected to the wireless controller; a linkage block is provided on the other side of the row pipe, and the linkage block is fixedly connected to the sliding sleeve, a reset rope is fixedly connected to one side of the linkage block, the outer wall of the reset rope is slidably connected to a buffer sleeve, and the buffer sleeve is fixedly connected to the arc-shaped collecting trough, and a gap is provided between the buffer sleeve and the sliding sleeve; a sliding sleeve is fixedly installed on one end of the arc-shaped collecting trough, and the sliding sleeve is slidably connected to the reset rope, and a counterweight cone is fixedly connected to the bottom end of the reset rope. The outer wall of the reset rope and the inner wall of the buffer sleeve are both smooth surfaces, and the inner wall of the sliding sleeve is a smooth surface. The counterweight cone is used to counterbalance the positioning rope, and the vertical cross-section of the buffer sleeve is rectangular.

[0009] When this technology is used, when the sliding sleeve moves right in an arc path, the positioning block approaches the distance sensor. When the distance sensed by the distance sensor is two centimeters, the wireless controller starts the micro-electric cylinder to drive the positioning pressure sensor downward, and the pressure ring drives the row pipe downward. The row pipe no longer contacts the suspension frame, and at the same time, the bottom end of the reset rope is driven downward under the action of the counterweight cone counterweight, and the reset rope slides along the inner wall of the buffer sleeve at the same time. The top of the reset rope drives the linkage block to move left, and the sliding sleeve moves left along the upper surface of the arc-shaped collection groove to reset. When the sliding sleeve contacts the buffer sleeve, the row pipe automatically resets to the initial position under the action of the counterweight cone counterweight.

[0010] Preferably, a conveying motor is installed at the top of the annular conveying frame, and the conveying motor is electrically connected to the wireless controller; the output end of the conveying motor is fixedly connected to the annular conveying frame, a suspension frame is fixedly installed on the upper surface of the conveying motor, a sleeve frame plate is fixedly connected to the outer wall of the suspension frame, the wireless controller is fixedly located on the upper surface of the sleeve frame plate, a positioning sleeve strip is fixedly installed at one end of the sleeve frame plate, and the positioning sleeve strip is fixedly connected to the arc-shaped collecting groove, the inner wall of the positioning sleeve strip is threadedly connected to a proximity sensor, and a protrusion is fixedly connected to the outer wall of each suspension frame. A linkage electric cylinder is provided on one side of the wireless controller.

[0011] The linkage electric cylinder is fixedly connected to the sleeve frame plate, the output end of the linkage electric cylinder is slidably connected to the sleeve frame plate, the output end of the linkage electric cylinder is fixedly connected to a rubber column, and a linkage pressure sensor is installed at the bottom end of the rubber column, the outer wall of the linkage pressure sensor is fixedly connected to a guide cylinder, the output ends of the rubber column and the linkage electric cylinder are both slidably connected to the guide cylinder, the bottom end of the guide cylinder is fixedly connected to an arc-shaped titanium-zinc plate, and the arc-shaped titanium-zinc plate and the linkage pressure sensor are fixedly connected; the inner wall of the suspension frame is plugged with a milk box, and an arc-shaped guide groove is provided on one side of the inner wall of the milk box, and the arc-shaped titanium-zinc plate is slidably connected to the milk box. The cross-sectional shape of the arc-shaped titanium-zinc plate is an arc, and the cross-sectional shape of the arc-shaped guide groove is an arc. The lower surface of the arc-shaped titanium-zinc plate is a smooth surface, and the inner wall of the arc-shaped guide groove is a smooth surface.

[0012] When this technology is in use, the milk box inside the hanging frame will slide along the lower surface of the arc-shaped titanium-zinc plate, the output end of the linkage electric cylinder will move down along the inner wall of the socket frame plate, the rubber column will drive the linkage pressure sensor to move down, the linkage pressure sensor will drive the arc-shaped titanium-zinc plate to move down, and the arc-shaped titanium-zinc plate will be pressed down along the arc-shaped guide groove inside the hanging frame. The arc-shaped guide groove on the hanging frame will rotate on the arc-shaped titanium-zinc plate. When the pressure value sensed by the linkage pressure sensor is the pressure value set by the wireless controller, and the pressure value is less than the sliding friction between the milk box and the arc-shaped titanium-zinc plate, it can ensure that the arc-shaped titanium-zinc plate can squeeze the milk box downward while allowing the milk box to rotate on the smooth surface of the lower surface of the arc-shaped titanium-zinc plate.

[0013] Technical effects and advantages of the present invention: 1. The present invention adopts a suspension following conveying component, and the discharge pipe is inserted into the weak paper position at the bottom of the milk box along the guide hole, and pressure sensing is performed through the positioning pressure sensor. As the suspension frame continues to rotate, the suspension frame drives the discharge pipe to rotate, and the sliding sleeve plate moves right along the arc path on the arc collecting groove. The sliding sleeve plate will simultaneously drive the sliding sleeve strip to move right along the arc path, and the sliding sleeve strip simultaneously moves right along the inner wall of the arc groove strip. The discharge pipe moves the milk body to the lower row along the inside of the arc collecting groove, and the milk body in the lower row is received along the arc collecting groove and enters the guide pipe of the coffee machine. During the continuous conveying process of multiple milk boxes, the milk body inside the milk box can be suspended and conveyed to the milk inlet of the coffee machine, which not only improves the overall suspension conveying efficiency, but also greatly extends the life of the equipment, and can realize the intelligent and precise filling of milk body without stopping the milk box conveying.

[0014] 2. The present invention uses the arc-shaped guide groove on the suspension frame to rotate on the arc-shaped titanium-zinc plate, and the linkage pressure sensor accurately senses the extrusion force of the rubber column. When the pressure reaches the setting value of the wireless controller and is less than the sliding friction between the milk box and the arc-shaped titanium-zinc plate, it not only ensures the downward extrusion of the milk box, but also enables the milk box to rotate on the smooth surface under the arc-shaped titanium-zinc plate, so as to realize the intelligent and rapid follow-up conveying of the milk in the milk box without stopping the machine. This design effectively avoids affecting the normal annular suspension conveying of the milk box, and can quickly convey the milk in the milk box to the discharge pipe, and then efficiently complete the subsequent conveying through the arc-shaped collection trough.

[0015] 3. The present invention uses a sliding sleeve to move right to make the positioning block close to the distance sensor. When the sensing value of the distance sensor reaches two centimeters, it indicates that the milk in the milk box is emptied. The micro-electric cylinder moves the discharge pipe downward to separate from the suspension frame, thereby realizing non-stop conveying of the empty milk boxes. The counterweight cone and the counterweight force drive the reset rope to move the linkage block to the left, so that the sliding sleeve and the discharge pipe move left along the arc-shaped collecting groove and reset, and the sliding sleeve automatically returns to the initial position after contacting the buffer sleeve, so as to continue to convey other milk boxes without stopping, thereby improving the overall suspension conveying efficiency, and the reset utilizes the counterweight force to save electricity.

[0032] In this embodiment, if Figure 8As shown, a conveying motor 23 is installed at the top of the annular conveying frame 1, and the conveying motor 23 is electrically connected to the wireless controller 25, and the conveying motor 23 is electrically connected to the wireless controller 25; the output end of the conveying motor 23 is fixedly connected to the annular conveying frame 1, and a suspension frame 24 is fixedly installed on the upper surface of the conveying motor 23, and a socket frame plate 26 is fixedly connected to the outer wall of the suspension frame 24, and the wireless controller 25 is fixedly located on the upper surface of the socket frame plate 26, and a positioning sleeve 27 is fixedly installed at one end of the socket frame plate 26, and the positioning sleeve 27 is fixedly connected to the arc-shaped collecting groove 5, and the inner wall of the positioning sleeve 27 is threadedly connected to a proximity sensor 28, and the outer wall of each suspension frame 2 is fixedly connected to a protrusion 29.

[0033] In this embodiment, if Figure 8 - Fig. 9 As shown, a linkage electric cylinder 30 is provided on one side of the wireless controller 25; the linkage electric cylinder 30 is fixedly connected to the socket frame plate 26, and the output end of the linkage electric cylinder 30 is slidably connected to the socket frame plate 26, and the output end of the linkage electric cylinder 30 is fixedly connected to a rubber column 31, and a linkage pressure sensor 32 is installed at the bottom end of the rubber column 31, and the outer wall of the linkage pressure sensor 32 is fixedly connected to a guide cylinder 33.

[0034] The output ends of the rubber column 31 and the linkage electric cylinder 30 are both slidably connected to the guide cylinder 33, the bottom end of the guide cylinder 33 is fixedly connected with an arc-shaped titanium-zinc plate 34, and the arc-shaped titanium-zinc plate 34 is fixedly connected to the linkage pressure sensor 32; the inner wall of the suspension frame 2 is plugged with a milk box 36, and an arc-shaped guide groove 35 is opened on one side of the inner wall of the milk box 36, and the arc-shaped titanium-zinc plate 34 is slidably connected to the milk box 36. The cross-sectional shape of the arc-shaped titanium-zinc plate 34 is an arc, and the cross-sectional shape of the arc-shaped guide groove 35 is an arc. The lower surface of the arc-shaped titanium-zinc plate 34 is a smooth surface, and the inner wall of the arc-shaped guide groove 35 is a smooth surface.

[0035] The method of using the coffee machine milk box intelligent hanging conveying system of the present invention is as follows: Step 1: When installing and docking, hang the top of the hanging frame 24 at the top position of the room, insert the expansion bolts into the top holes of the hanging frame 24, and the hanging frame 24 can be hung and fixed. The hanging frame 24 supports the conveying motor 23, and the hanging frame 24 supports the sleeve frame plate 26, the sleeve frame plate 26 supports the positioning sleeve strip 27, and the positioning sleeve strip 27 supports the arc-shaped collecting trough 5 to increase the stability of the arc-shaped collecting trough 5. At the same time, insert multiple milk boxes 36 into multiple hanging frames 2 for placement, and then insert the coffee machine guide pipe 15 into the milk inlet position of the coffee machine.

[0036] Step 2: During the circular suspension conveying, the conveying motor 23 is started by the wireless controller 25, and the conveying motor 23 drives the circular conveying frame 1 to rotate, and the circular conveying frame 1 drives the plurality of suspension frames 2 to rotate, and the suspension frames 2 drive the milk box 36 to rotate, and the milk box 36 is located at the lower surface of the arc-shaped titanium zinc plate 34. At the same time, the suspension frame 2 drives the protrusion 29 to rotate, and the protrusion 29 is located at the sensing end of the proximity sensor 28.

[0037] Step 3, when the suspension follows the conveying, when the protrusion 29 is located at the sensing end position of the proximity sensor 28, the micro-electric cylinder 14 is started simultaneously through the wireless controller 25, and the micro-electric cylinder 14 pushes the positioning pressure sensor 13 to move up, and the positioning pressure sensor 13 can drive the pressure ring 12 to move up, and the pressure ring 12 drives the silicone ring 11 to move up, and at the same time, the silicone ring 11 is squeezed and fitted on the lower surface of the suspension frame 2, and the positioning pressure sensor 13 performs pressure sensing. When the pressure value sensed by the positioning pressure sensor 13 is the same as the pressure value set by the wireless controller 25, the micro-electric cylinder 14 is closed by the wireless controller 25. The pressure ring 12 will simultaneously drive the row pipe 3 to move up, and the row pipe 3 is inserted into the weak paper position at the bottom of the milk box 36 along the guide hole 9, and the arc-shaped titanium zinc plate 34 supports the upper surface of the milk box 36. In this way, the row pipe 3 can be stably inserted into the interior of the milk box 36, that is, the row pipe 3 is connected to the milk box 36.

[0038] As the suspension frame 2 continues to rotate and transport, the suspension frame 2 drives the discharge pipe 3 to rotate, and the discharge pipe 3 drives the sliding sleeve plate 4 to rotate. The sliding sleeve plate 4 moves right along the arc path on the arc collecting groove 5, and the sliding sleeve plate 4 will simultaneously drive the sliding sleeve strip 6 to move right along the arc path. The sliding sleeve strip 6 moves right along the outer wall of the arc rail 7, and the sliding sleeve strip 6 simultaneously moves right along the inner wall of the arc groove strip 8. In this way, when the milk box 36 rotates, the milk can be transported into the discharge pipe 3, and the discharge pipe 3 moves the milk to the lower row along the inside of the arc collecting groove 5. The milk in the lower row is received along the arc collecting groove 5 and enters the coffee machine guide pipe 15, and the coffee machine guide pipe 15 directly transports the milk to the milk inlet of the coffee machine. At the same time, the sliding sleeve 4 drives the linkage block 18 to move right, the linkage block 18 drives the reset rope 19 to move right, the reset rope 19 slides right along the inner wall of the buffer sleeve 20, and the reset rope 19 slides right along the inner wall of the buffer sleeve 20, and the reset rope 19 drives the counterweight cone 22 to move upward.

[0039] Step 4: When following constant-pressure transportation, the milk carton 36 inside the hanging frame 2 will slide along the lower surface of the arc-shaped titanium-zinc plate 34. Meanwhile, the linkage electric cylinder 30 is started through the wireless controller 25. The output end of the linkage electric cylinder 30 moves downward along the inner wall of the socket frame plate 26. The output end of the linkage electric cylinder 30 drives the rubber column 31 to move downward. The rubber column 31 drives the linkage pressure sensor 32 to move downward. The linkage pressure sensor 32 drives the arc-shaped titanium-zinc plate 34 to move downward. In this way, the arc-shaped titanium-zinc plate 34 will press downward along the arc-shaped guide groove 35 inside the hanging frame 2.

[0040] Meanwhile, the arc-shaped guide groove 35 on the hanging frame 2 will rotate on the arc-shaped titanium-zinc plate 34. By sensing the extrusion force of the rubber column 31 through the linkage pressure sensor 32, when the pressure value sensed by the linkage pressure sensor 32 is the pressure value set by the wireless controller 25 and the pressure value is less than the sliding friction force between the milk carton 36 and the arc-shaped titanium-zinc plate 34, it can ensure that while the arc-shaped titanium-zinc plate 34 presses the milk carton 36 downward, the milk carton 36 can also rotate on the smooth lower surface of the arc-shaped titanium-zinc plate 34, without affecting the normal circular rotation transportation of the milk carton 36. During the non-stop transportation process of the milk carton 36, the milk inside the milk carton 36 can be quickly transported into the discharge pipe 3, and then quickly transported into the arc-shaped collection tank 5 through the discharge pipe 3.

[0041] Step 5: When performing weight matching and resetting, when the sliding sleeve plate 4 moves rightward along the arc path, the positioning block 16 will move rightward along the arc path. The positioning block 16 approaches the distance sensor 17. When the distance sensed by the distance sensor 17 is two centimeters, at this time, the discharge pipe 3 follows the milk carton 36 to move to the end position, which means the milk inside the milk carton 36 has been completely discharged. Then, the wireless controller 25 starts the micro electric cylinder 14 to drive the positioning pressure sensor 13 to move downward. The positioning pressure sensor 13 drives the pressure ring 12 to move downward. The pressure ring 12 drives the discharge pipe 3 to move downward. The discharge pipe 3 no longer contacts the hanging frame 2. Thus, the hanging frame 2 can transport the used milk cartons out without stopping the machine.

[0042] Meanwhile, under the action of the gravity of the weight cone 22, the bottom end of the reset rope 19 moves downward. The reset rope 19 slides along the inner wall of the sliding sleeve block 21 and also along the inner wall of the buffer sleeve plate 20. The top end of the reset rope 19 drives the linkage block 18 to move leftward. The linkage block 18 drives the sliding sleeve plate 4 to move leftward along the arc path for resetting. The sliding sleeve plate 4 moves leftward along the upper surface of the arc-shaped collection tank 5 for resetting. The sliding sleeve plate 4 drives the discharge pipe 3 to move leftward along the arc path for resetting. When the sliding sleeve plate 4 contacts the buffer sleeve plate 20, the discharge pipe 3 automatically resets to the initial position under the action of the gravity of the weight cone 22. In this way, the discharge pipe 3 continues to perform non-stop following transportation of the milk inside other milk cartons 36.
