Description

Technical Field

[0001] This utility model relates to the field of workshop conveyor technology, and in particular to a cup lid picking and placing unit. Background Technology

[0002] Before packaging cup-shaped products, the lids need to be conveyed to a predetermined position. Before they arrive, the spacing between the lids varies and is not uniform. Some are very close together, even partially overlapping, while others have a larger gap. There are certain requirements for the spacing between the lids and the time it takes for them to arrive at the predetermined position. If the lids arrive too early, the utensils may not have been placed yet, and the lids may have already been placed. This will cause misplacement. Moreover, if the spacing between the lids is not uniform, it will be difficult to place the utensils, as the utensils placement device is also set with a placement interval. If the spacing between the lids is not uniform, it will cause placement deviation, affect the efficiency of placement, and affect subsequent processing steps.

[0003] To address this technical problem, the invention with application number CN201821812955.7 discloses a synchronous cap feeding mechanism, including a frame, a cap feeding chute for conveying caps, a cap-pulling belt forming a closed loop wound on cap-pulling wheels on each side, and multiple cap-pulling blocks for actuating the caps symmetrically and evenly installed on the cap-pulling belts on both sides; a baffle plate that is opened by the pressure of the cap is provided on the frame at the junction of the cap feeding channel inlet and the cap feeding chute outlet, and a first rotating shaft passes through the middle of the baffle plate; a signal block is provided below the cap feeding channel inlet, and a detection photoelectric sensor connected to the control system is provided below the signal block, and a second rotating shaft passes through the middle of the signal block, and the signal block is inclined with its head pointing upwards and its tail contacting the detection photoelectric sensor, and the head of the signal block touches the bottom end of the cap after passing through the baffle plate.

[0004] However, this technical solution has the following drawbacks: a single cap-grabbing mechanism is limited by the physical movement cycle of the robotic arm, and can only complete the grabbing and placement operation of a single set of caps on the line in each work cycle, which is difficult to match the cycle time requirements of high-speed filling lines; some manufacturers have tried to improve efficiency through a parallel dual-channel structure, but this requires repeated configuration of two independent grabbing systems, drive modules and control systems, which leads to an exponential increase in equipment complexity, as well as problems such as doubling of manufacturing costs and increased maintenance difficulty. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a cup lid taking and placing unit, comprising:

[0006] An equidistant conveying mechanism is provided, wherein multiple sets of equidistant conveying mechanisms are arranged in parallel and at equal intervals. A mold is fixed on the conveying drive of the equidistant conveying mechanism. Multiple molds are provided and are arranged at equal intervals along the conveying direction of the conveyor belt. A groove matching the cup lid is provided on the surface of the mold.

[0007] A cup lid picking and placing mechanism is set at a preset position on an equidistant conveying mechanism. The cup lid picking and placing mechanism can simultaneously pick up at least one cup lid from multiple sets of the equidistant conveying mechanisms.

[0008] The cup lid taking and placing mechanism includes:

[0009] Installation Department;

[0010] A second power unit is fixedly installed on the mounting part;

[0011] A connecting rod, one end of which is rotatably connected to the mounting part, and driven by a second power device to rotate the connecting rod around the end where it is connected to the mounting part;

[0012] A cap-removing module is rotatably connected to the end of a connecting rod away from the mounting part. The cap-removing module has multiple cap clamping groups arranged corresponding to the equidistant conveying mechanism, and each cap clamping group is provided with at least one cap clamp.

[0013] The connecting shaft between the connecting rod and the mounting part is maintained through a synchronous belt drive mechanism and the connecting shaft between the connecting rod and the cover removal module.

[0014] This invention combines the equidistant layout of the mold grooves with the synchronous movement of the conveyor belt, which allows the cup lids to maintain a fixed spacing during the conveying process. When the cup lid is conveyed to the cup lid picking and placing mechanism, the second power device drives the lid picking module to move above the cup lid, and the lid clamping device actuates to clamp and fix the cup lid. Since there are multiple sets of lid clamping devices, and these multiple sets of lid clamping devices are arranged in parallel and equidistantly corresponding to the equidistant conveying mechanism, a single action of the lid picking module can realize the synchronous grabbing of multiple cup lids from multiple sets of equidistant conveying mechanisms. This enables a single lid picking mechanism to grab cup lids from multiple conveying channels, improving work efficiency and reducing equipment complexity and maintenance costs.

[0015] Furthermore, the cup lid picking and placing unit also includes a partition conveying mechanism. The partition conveying mechanism is provided in multiple sets, each set having a horizontal section and an inclined section. The partition conveying mechanism drives the cup lid to move from the horizontal section to the inclined section. At the end of the horizontal section of each set of partition conveying mechanisms, there is a lid-splitting mechanism. This lid-splitting mechanism stores multiple sets of stacked cup lids formed by stacking multiple cup lids in a limited quantity, and picks up the bottom cup lid of each stacked cup lid set and places it on the partition conveying mechanism. At the end of the inclined section of each set of partition conveying mechanisms, there is a buffer conveying mechanism. This buffer conveying mechanism receives the cup lids output by the partition conveying mechanism and drives the cup lids to move slowly. The buffer conveying mechanism is connected to the equidistant conveying mechanism.

[0016] Furthermore, the cover-opening mechanism includes:

[0017] The cup lid storage section is provided in multiple sets, and the multiple sets of cup lid storage sections are equidistantly arranged along the conveying direction of the horizontal section of the partition conveying mechanism.

[0018] A baffle device is provided below the lid storage section to block or release the lids inside the lid storage section.

[0019] First power unit;

[0020] The lid-separating part is located entirely below the material-blocking device. The lid-separating part moves vertically and rotates 180° via a first power device. The lid-separating part includes multiple sets of lid-removing devices corresponding to the cup lid storage part.

[0021] The first power unit drives the lid-separating part to move vertically and rotate 180° in a combined action, thereby separating the bottom single lid of the stacked cup lid group. During the separation process, the baffle device blocks the cup lid above the bottom single lid of the stacked cup lid group, thereby reducing and avoiding the stacking and sticking caused by traditional suction cup lid separation, and improving work efficiency.

[0022] Furthermore, a guide channel is provided at one end of the inclined section of the partition conveying mechanism, and the outlet of the guide channel is connected to a cover outlet channel, which is connected to the buffer conveying mechanism.

[0023] The guide channel can guide the movement of the cup lid, so that the lid slides into the lid outlet channel and finally slides down along the lid outlet channel onto the buffer conveyor mechanism, thereby so that the cup lid is sent to the buffer conveyor mechanism in an orderly manner.

[0024] Furthermore, a cup lid receiving platform is provided at the connection between the equidistant conveying mechanism and the buffer conveying mechanism. A contoured star wheel is rotatably mounted on the cup lid receiving platform. The contoured star wheel is driven to rotate by a third power device installed on the lower surface of the cup lid receiving platform, so as to drive the cup lid of the cup lid receiving platform to move into the groove.

[0025] Furthermore, a guide block parallel to the movement trajectory of the cup lid is fixed on one side of the cup lid receiving platform. The guide block extends from the connection between the cup lid receiving platform and the buffer conveying mechanism to the side of the conveying mechanism away from the buffer conveying mechanism.

[0026] When the cup lid reaches the cup lid receiving platform, the third power device drives the contour star wheel to rotate, so that the cup lid moves along the inside of the guide block. When the cup lid moves to the mold, the cup lid falls into the groove.

[0027] This utility model has the following advantages:

[0028] This invention combines the equidistant layout of the mold grooves with the synchronous movement of the conveyor belt, which allows the cup lids to maintain a fixed spacing during the conveying process. When the cup lid is conveyed to the cup lid picking and placing mechanism, the second power device drives the lid picking module to move above the cup lid, and the lid clamping device actuates to clamp and fix the cup lid. Since there are multiple sets of lid clamping devices, and these multiple sets of lid clamping devices are arranged in parallel and equidistantly corresponding to the equidistant conveying mechanism, a single action of the lid picking module can realize the synchronous grabbing of multiple cup lids from multiple sets of equidistant conveying mechanisms. This enables a single lid picking mechanism to grab cup lids from multiple conveying channels, improving work efficiency and reducing equipment complexity and maintenance costs.

[0046] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0047] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0048] As described in the background section, a single cap-grabbing mechanism is limited by the physical movement cycle of the robotic arm, and can only complete the grasping and placement operation of a single set of caps per work cycle, making it difficult to match the cycle time requirements of high-speed filling lines. Some manufacturers have attempted to improve efficiency through a parallel dual-channel structure, but this requires repeatedly configuring two independent grasping systems, drive modules, and control systems, leading to an exponential increase in equipment complexity, as well as problems such as doubling manufacturing costs and increasing maintenance difficulty.

[0049] Example 1:

[0050] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a cup lid taking and placing unit, such as... Figure 1 As shown, the pick-and-place unit includes:

[0051] Equidistant conveying mechanism 300, wherein multiple sets of equidistant conveying mechanisms are arranged in parallel and at equal intervals, such as... Figure 10 As shown, a mold 310 is fixed on the conveyor belt of the equidistant conveyor mechanism. Multiple molds are provided and are equidistantly arranged along the conveyor belt direction. A groove 311 matching the cup lid is provided on the surface of the mold.

[0052] A cup lid picking and placing mechanism 500 is set at a preset position on an equidistant conveying mechanism. The cup lid picking and placing mechanism can simultaneously pick up at least one cup lid from multiple sets of the equidistant conveying mechanisms.

[0053] like Figure 11 As shown, the cup lid taking and placing mechanism includes:

[0054] Installation section 510;

[0055] The second power unit 520 is fixedly installed on the mounting part;

[0056] Link 530, one end of which is rotatably connected to the mounting part, and is driven by a second power device to rotate around the connection end with the mounting part;

[0057] A cap-removing module 550 is rotatably connected to the end of a connecting rod away from the mounting part. The cap-removing module has multiple cap clamping groups arranged corresponding to the equidistant conveying mechanism, and each cap clamping group is provided with at least one cap clamp.

[0058] The connecting shaft between the connecting rod and the mounting part is maintained through a synchronous belt drive mechanism 540 and the connecting shaft between the connecting rod and the cover removal module.

[0059] In this embodiment, the cup lid is placed into the groove of the mold, and the cup lid is moved to the cup lid picking and placing mechanism by the equidistant conveying mechanism. When the cup lid is conveyed to the designated position, the second power device drives the connecting rod to rotate. Due to the power transmission of the synchronous belt drive mechanism, the lid picking module also rotates when the connecting rod rotates, thus keeping the lid picking module in a horizontal state when the connecting rod rotates. When the lid picking module moves to the cup lid position, the lid picker is activated, clamping and fixing the cup lids at the designated positions on the multiple sets of equidistant conveying mechanisms at the same time. Then the second power device is activated again to place the cup lid in the designated position.

[0060] This embodiment combines the equidistant layout of the mold grooves with the synchronous movement of the conveyor belt, which allows the cup lids to maintain a fixed spacing during the conveying process. When the cup lid is conveyed to the cup lid picking and placing mechanism, the second power device drives the lid picking module to move above the cup lid, and the lid clamping device actuates to clamp and fix the cup lid. Since there are multiple sets of lid clamping devices, and these multiple sets of lid clamping devices are arranged in parallel and equidistantly corresponding to the equidistant conveying mechanism, a single action of the lid picking module can realize the synchronous grabbing of multiple cup lids from multiple sets of equidistant conveying mechanisms. This enables a single lid picking mechanism to grab cup lids from multiple conveying channels, improving work efficiency and reducing equipment complexity and maintenance costs.

[0061] In this embodiment, the second power device may be a servo motor, a stepper motor, or other device capable of driving the connecting rod to rotate around one end.

[0062] In addition, such as Figure 1 As shown, the cup lid picking and placing unit may further include a partition conveying mechanism 200. The partition conveying mechanism is provided in multiple sets, each set having a horizontal section and an inclined section. The partition conveying mechanism drives the cup lid to move from the horizontal section to the inclined section. At the end of the horizontal section of each set of partition conveying mechanisms, a lid separating mechanism 100 is provided. The lid separating mechanism stores multiple sets of stacked cup lids formed by stacking multiple cup lids in a limited quantity, and picks up the bottom cup lid of each stacked cup lid set and places it on the partition conveying mechanism. At the end of the inclined section of each set of partition conveying mechanisms, a buffer conveying mechanism 400 is connected. The buffer conveying mechanism receives the cup lids output by the partition conveying mechanism and drives the cup lids to move slowly. The buffer conveying mechanism is connected to the equidistant conveying mechanism.

[0063] For example, such as Figures 2-5As shown, the cover-opening mechanism includes:

[0064] The cup lid storage section 130 is provided in multiple sets, and the multiple sets of cup lid storage sections are equidistantly arranged along the conveying direction of the horizontal section of the partition conveying mechanism.

[0065] A baffle device 150 is provided below the cup lid storage section to block or release the cup lid inside the cup lid storage section;

[0066] First power unit 120;

[0067] The lid-separating part 140 is integrally arranged below the material-blocking device. The lid-separating part moves vertically and rotates 180° via a first power device. The lid-separating part includes multiple sets of lid-removing devices 142 corresponding to the cup lid storage part.

[0068] This embodiment achieves the separation of the bottom single cap of the stacked cup cap group by using a combination of vertical linear movement and 180° rotation driven by a first power device. During the separation process, a baffle device blocks the cup caps above the bottom single cap of the stacked cup cap group, thereby reducing and avoiding the stacking and sticking caused by traditional suction cup separation, and improving work efficiency. In this embodiment, the cap separation mechanism may also include a frame 110, on which the first power device, the cap separation part, and the cup cap storage part are all mounted.

[0069] In this embodiment, the first power device may be selected from a cylinder, an electric cylinder, a hydraulic cylinder, or other devices capable of achieving linear movement of the cover section.

[0070] This embodiment provides a structure that can rotate 180° during the linear movement of the cover section, such as... Figures 4-6 As shown, the cover portion may further include:

[0071] The sliding part 144 is driven to slide vertically by the aforementioned first power device;

[0072] A rotating shaft 141 is rotatably connected to the aforementioned sliding part;

[0073] A rotating gear 145 is fixedly installed at the end of the aforementioned rotating shaft. One end of the rotating gear is provided with a linear groove 145A, and rotating grooves 145B are provided on both sides of the rotating gear away from the end of the linear groove.

[0074] A linear cam follower 147 is provided, which corresponds to the linear slide groove mentioned above. There are two sets of the linear cam follower, which are arranged vertically opposite each other.

[0075] A rotary cam follower 148 is provided, and a rotary slide 162 is provided corresponding to the rotary cam follower. The rotary cam follower 193 is provided between the linear cam followers.

[0076] In this embodiment, the sliding part is driven to slide vertically by the first power device, so that the rotating shaft slides vertically accordingly. Due to the limiting action of the linear cam follower 193 and the linear groove, the rotating shaft will first make a small vertical linear movement, such as... Figure 7 As shown, after the rotary gear disengages from the linear cam follower, the rotary cam follower enters the rotary groove, as... Figure 8 As shown, the rotating gear continues to slide. When the rotating cam follower contacts the end of the rotating slide, because the rotating slide is offset from the center of the rotating shaft, the rotating cam follower will push the rotating gear to rotate. During the rotation, the rotating gear will continue to move linearly until the rotating gear flips 180°. Then, the rotating cam follower disengages from the rotating slide, and another linear cam follower enters the linear slide. The rotating gear continues to move linearly for a distance, realizing that the cap clamping head on the rotating shaft moves up and down while simultaneously flipping 180°, thereby realizing the cap taking and putting actions, improving work efficiency.

[0077] In this embodiment, as Figure 5 As shown, the above-mentioned cover-opening mechanism may also include a fixing part 146, on which the first power device may be fixedly installed. The linear cam follower and the rotary cam follower may be fixedly installed on the inner side of the mounting part, and the fixing part is fixed to the frame.

[0078] like Figure 5 As shown, the above-mentioned cap-removing assembly may further include a guide portion 143, which is slidably connected to the above-mentioned sliding portion. This guide portion can be selected as follows: Figure 5 The guide rod shown is vertically fixed to the aforementioned fixed part, and the guide rod passes through the sliding part and slides relative to the sliding part. Alternatively, a guide rail can be selected, and the sliding part is connected to the guide rail via a slider. The guide part guides the movement of the sliding part, improving the movement accuracy of the sliding part.

[0079] In this embodiment, as Figure 9 As shown, a guide channel 210 is provided at one end of the inclined section of the partition conveying mechanism, and the outlet of the guide channel is connected to a cover outlet channel 220, which is connected to the buffer conveying mechanism.

[0080] When the cup lid is conveyed to its end by the partition conveyor, it moves towards the discharge channel under the guidance of the guide channel, and finally slides down onto the buffer conveyor along the lid discharge channel, so that the cup lid is sent to the buffer conveyor in an orderly manner.

[0081] For example, such as Figure 10As shown, a cup lid receiving platform 330 is also provided at the connection between the equidistant conveying mechanism and the buffer conveying mechanism. A contoured star wheel 320 is rotatably installed on the cup lid receiving platform. The contoured star wheel is driven to rotate by a third power device installed on the lower surface of the cup lid receiving platform, so as to drive the cup lid of the cup lid receiving platform to move into the groove.

[0082] In this embodiment, a guide block 340 parallel to the movement trajectory of the cup lid is fixed on one side of the cup lid receiving platform. The guide block extends from the connection between the cup lid receiving platform and the buffer conveying mechanism to the side of the conveying mechanism away from the buffer conveying mechanism.

[0083] When the cup lid reaches the cup lid receiving platform, the third power device drives the contour star wheel to rotate, so that the cup lid moves along the inside of the guide block. When the cup lid moves to the mold, the cup lid falls into the groove.

[0084] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
