Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and more specifically, it relates to an automatic cup-grabbing device. Background Technology

[0002] In today's booming coffee industry, the efficiency and convenience of coffee machines have become key factors in market competition. As an important component of coffee machines, the performance of the automatic cup dispensing mechanism directly impacts user experience and production and operating costs.

[0003] Currently available automatic cup dispensers generally suffer from significant drawbacks. In terms of functional adaptability, existing automatic cup dispensers have poor compatibility with different sized paper cups. Because paper cups come in various sizes, such as the common 8 ounce, 12 ounce, and 16 ounce sizes, existing automatic cup dispensers require tedious adjustments by professional technicians when handling these different sized cups. Each time the cup size is changed, parameters such as the spacing and gripping force of the mechanical gripping mechanism must be reset. This process is not only time-consuming and labor-intensive but also demands a high level of professional skill from the operators.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an automatic cup-grabbing device in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic cup-grabbing device, which is achieved by the following specific technical means:

[0006] An automatic cup-grabbing and dropping device includes a cup container and paper cups. Three sets of mounting slots and clearance slots are equally spaced on the upper and lower sides of the cup container's side wall. Paper cup pushers and paper cup hooks are respectively installed in the three clearance slots and mounting slots. Each of the three paper cup hooks has a mounting shaft installed through one end, and each hook is rotatably connected to the inner wall of the corresponding mounting slot via both ends of the mounting shaft. Torsion springs are fitted onto the outer walls of the three mounting shafts to maintain the paper cup hooks in their initial state of releasing the paper cup. A cylindrical slider is installed at the top of each of the three paper cup pushers. The cylindrical slider is used to clamp and release the paper cup hooks and pushers. The cylindrical slider is slidably mounted on the side wall of the cup container. A drive mechanism for raising and lowering the cylindrical slider is provided on the side wall of the cup container. The cross-sections of the three paper cup hooks and pushers are all tapered.

[0007] Preferably, the driving mechanism includes a motor mounted on the side wall of the cup container, with a lead screw connected to the output end of the motor. A driving block is threadedly connected to the outer wall of the lead screw via a ball nut. The driving block is fixedly connected to the side wall of the cylindrical slider. A first touch switch and a second touch switch are also installed on the side wall of the cup container. Both the first touch switch and the second touch switch are electrically connected to the motor via wires. The first touch switch and the second touch switch are respectively arranged opposite to the upper and lower sides of the cylindrical slider. Top columns for driving the paper cup hooks to rotate are slidably installed at the bottom of the three sets of mounting slots.

[0008] Preferably, the side wall of the cup barrel is provided with three sets of through slots through which the bottom ends of the top columns pass. The bottom ends of the three sets of top columns pass through the through slots and are fixedly connected to the inner wall of the cylindrical slider. The bottom ends of the three sets of top columns are slidably connected to the inner wall of the corresponding through slot.

[0009] Preferably, the two ends of the torsion spring are respectively positioned abutting against the paper cup hook gripping side and the outside of the mounting groove.

[0010] Preferably, silicone pads are adhered to the gripping ends of the three sets of paper cup hooks and the clamping ends of the three sets of paper cup pushers.

[0011] Preferably, the side wall of the cup holder is provided with three sets of sliding grooves at equal angles, and the three sets of sliding grooves are all set at the top of the three sets of clearance grooves, and the side walls of the three sets of paper cup pushers abut against the bottom of the corresponding sliding grooves.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The paper cup pusher and paper cup hook of this utility model are both cone-shaped. Unlike the traditional fixed-size gripping structure, the cone-shaped paper cup pusher and paper cup hook can automatically adjust the angle and force of gripping and clamping according to the size of the paper cup. When facing a smaller paper cup, the tip of the cone can fit tightly against the outer wall of the paper cup to ensure a stable grip. For larger paper cups, as the diameter of the paper cup increases, the lower part of the cone structure gradually contacts the paper cup, which can also provide a reliable clamping force. This adaptive design greatly improves the versatility of the device. Unlike traditional devices, there is no need for cumbersome adjustments or replacement of parts for different sizes of paper cups. This effectively saves time and labor costs and has high convenience.

[0014] 2. This utility model utilizes a drive mechanism to move a cylindrical slider. During its ascent, the slider pusher rises and abuts against the top of the clearance groove to dispense the cup. Simultaneously, the top column clamps the cup with a hook. This synergy ensures efficient and orderly transfer of the cup, significantly improving the accuracy and efficiency of automated operation and laying the foundation for automatic cup dispensing. When the top side of the cylindrical slider touches the first touch switch, the motor reverses, causing it to descend. Due to the torsion spring, the cup hook releases and the pusher clamps the cup. Based on the feedback control of the touch switch, a stable cycle is formed. Each cycle accurately completes the cup gripping and release, greatly enhancing the reliability and stability of the device. It can effectively cope with different working scenarios, demonstrating outstanding advantages in the field of automatic cup dispensing and powerfully promoting the efficient operation and development of related equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides an automatic cup-grabbing and dropping device, including a cup container 2 and a paper cup 1. The upper and lower sides of the side wall of the cup container 2 are provided with three sets of mounting grooves 14 and clearance grooves 12 at equal angles. Paper cup pushers 8 and paper cup hooks 6 are respectively arranged in the three sets of clearance grooves 12 and mounting grooves 14. One end of each of the three sets of paper cup hooks 6 is installed through a mounting shaft 15, and each is rotatably connected to the inner wall of the corresponding mounting groove 14 through the two ends of the mounting shaft 15. The outer wall of each of the three sets of mounting shafts 15 is fitted with a torsion spring 16, which is used to keep the paper cup hooks 6 in the initial state of releasing the paper cup 1. The top of the three sets of paper cup pushers 8 is jointly installed with a cylindrical slider 7, which is used to realize the clamping and releasing of the paper cup hooks 6 and paper cup pushers 8. The cylindrical slider 7 is slidably installed on the side wall of the cup container 2. The side wall of the cup container 2 is provided with a drive mechanism for driving the cylindrical slider 7 to rise and fall. The cross-section of each of the three sets of paper cup hooks 6 and paper cup pushers 8 is conical.

[0025] The driving mechanism includes a motor 3 mounted on the side wall of the cup 2. A lead screw 10 is connected to the output end of the motor 3. A drive block 11 is threadedly connected to the outer wall of the lead screw 10 via a ball nut. The drive block 11 is fixedly connected to the side wall of the cylindrical slider 7. A first touch switch 4 and a second touch switch 5 are also installed on the side wall of the cup 2. Both the first touch switch 4 and the second touch switch 5 are electrically connected to the motor 3 via wires. The first touch switch 4 and the second touch switch 5 are respectively positioned opposite to the upper and lower sides of the cylindrical slider 7. The bottom ends of the three sets of mounting slots 14 are slidably installed with... The top column 17, which drives the paper cup hook 6 to rotate, uses the motor 3 as a power source. Through the rotation of the lead screw 10, the rotational motion is efficiently converted into the linear motion of the drive block 11 by the ball nut, thereby precisely controlling the lifting and lowering of the cylindrical slider 7. This transmission method has high precision and can ensure that the paper cup hook 6 and the paper cup pusher 8 accurately reach the predetermined position when performing the action of grasping and releasing paper cups. This improves the accuracy of the automated operation of the entire device and reduces paper cup grasping failure or damage caused by position deviation. It is suitable for paper cup dispensing scenarios with strict precision requirements.

[0026] The cup barrel 2 has three sets of through slots on its side wall for the bottom ends of the top columns 17 to pass through. The bottom ends of the three sets of top columns 17 all pass through the through slots and are fixedly connected to the inner wall of the cylindrical slider 7. The bottom ends of the three sets of top columns 17 are slidably connected to the inner wall of the corresponding through slot. This design ensures that the top columns 17 have stable support and smooth sliding when moving with the cylindrical slider 7. On the one hand, it ensures the reliability of the transmission between the top columns 17 and the paper cup hook 6, so that the action of the paper cup hook 6 can be accurately executed. On the other hand, the reasonable layout of the through slots does not affect the overall structural strength of the cup barrel 2, optimizes the utilization of internal space, and makes the structure of the device more compact.

[0027] The torsion spring 16 is positioned with its two ends abutting against the gripping side of the paper cup hook 6 and the outside of the mounting groove 14, respectively. This provides a stable elastic restoring force for the paper cup hook 6. In the initial state, it ensures that the paper cup hook 6 is in the state of releasing the paper cup, making it convenient to put the paper cup into the cup container 2. After the paper cup is gripped, when the drive mechanism causes the paper cup hook 6 to release, the torsion spring 16 can promptly reset it, preparing for the next gripping action. This ensures the continuity and reliability of the device's gripping action, simplifies the control process, and reduces the dependence on complex control systems.

[0028] The gripping ends of the three sets of paper cup hooks 6 and the clamping ends of the three sets of paper cup pushers 8 are all bonded with silicone pads 9. The silicone pads 9 are soft and have high friction. During the gripping and clamping of paper cups, they can increase the friction with the paper cups, ensuring that the paper cups can be firmly held even when the device vibrates or operates rapidly, preventing the paper cups from falling. They can also effectively prevent the hard hooks and pushers from directly contacting the paper cups, preventing scratches and protecting the integrity of the paper cups. They are suitable for paper cups of different paper qualities, improving the device's compatibility with different paper cup qualities and ensuring the safety and hygiene of the beverages subsequently served in the paper cups.

[0029] The cup container 2 has three sets of sliding grooves 13 at equal angles on its side wall. Each of the three sets of sliding grooves 13 corresponds to the top of the three sets of clearance grooves 12. The side walls of the three sets of paper cup pushers 8 abut against the bottom of the corresponding sliding grooves 13. The sliding grooves 13 provide precise guidance and limit for the paper cup pushers 8. During the process of the paper cup pushers 8 rising and falling with the cylindrical slider 7, their movement trajectory is more stable and controllable, avoiding deviation or shaking. This ensures that the paper cup pushers 8 and the top of the clearance grooves 12 are reliably matched, realizing the smooth ejection of the paper cup. This further improves the overall stability and reliability of the device and reduces the risk of failure caused by unstable component movement.

[0030] The working principle of this embodiment is as follows: In the initial state, the cup container 2 contains paper cups, and the paper cup hook 6 is in a state of releasing the paper cup 1 under the action of the torsion spring 16. When the paper cup gripping operation is started, the motor 3 starts to run, and its output end drives the lead screw 10 to rotate. With the help of the threaded engagement between the ball nut and the lead screw 10, the drive block 11 drives the cylindrical slider 7 to move upward along the side wall of the cup container 2. During this process, the top column 17 rises with the cylindrical slider 7. Based on the transmission connection between the top column 17 and the paper cup hook 6, the paper cup hook 6 rotates around the mounting shaft 15, overcoming the elastic force of the torsion spring 16 to grip the bottommost paper cup 1. As the cylindrical slider 7 continues to rise, when it contacts the first touch switch 4, the motor 3 reverses and drives the cylindrical slider 7 to descend. At this time, the paper cup hook 6 is in... The paper cup begins to release under the action of the torsion spring 16. When the bottom side of the cylindrical slider 7 contacts the second touch switch 5, the motor 3 reverses again, causing the cylindrical slider 7 to rise. During this period, the paper cup pusher 8 rises with the cylindrical slider 7, and its side wall contacts the top of the clearance groove 12 and gradually opens. At the same time, the paper cup hook 6 completes the release action. The paper cup that was originally clamped falls down and is caught and clamped by the paper cup pusher 8. When the cylindrical slider 7 contacts the first touch switch 4 again, the top column 17 rises again, the paper cup hook 6 re-enters the clamping state, and the paper cup pusher 8 gradually opens, thus successfully completing the cup dispensing action. The whole process forms a stable cycle, realizing efficient and accurate gripping and release of paper cups, and can automatically adapt to paper cups of different sizes, ensuring the stable operation of the device.
