Description

Technical Field

[0001] This application relates to the field of plastic cigarette holder manufacturing technology, and in particular to a plastic cigarette holder tray loading equipment and production system. Background Technology

[0002] The production process of plastic cigarette holders faces numerous challenges. Firstly, the number of cavities in the production molds is often limited. This directly restricts output per unit time, failing to meet the demands of large-scale, high-speed production. Furthermore, the crucial online tray loading process lacks full automation. This means that manual intervention or semi-automation is required between the product leaving the mold and being loaded onto the tray.

[0003] Due to the limitations of manual or semi-automated palletizing methods, products are highly susceptible to contamination. Dust, impurities, and other contaminants in the production environment easily adhere to the plastic cigarette holders, affecting product quality. Furthermore, the lack of effective automated protection mechanisms during handling and palletizing allows products to easily collide with each other, resulting in damage. These damages not only affect the product's appearance but, in some cases, may also compromise its structural integrity, rendering the product unusable.

[0004] Furthermore, low production efficiency is a combined result of these problems. From the limited number of mold cavities restricting output to the non-automation of the tray loading process affecting the overall production rhythm, the entire production process is time-consuming and cannot meet the market's demand for high-speed production of plastic cigarette holders, severely restricting the company's production capacity and economic benefits.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] In view of at least one of the above technical problems, this application provides a plastic cigarette holder tray loading device and production system.

[0007] In a first aspect, a plastic cigarette holder loading device is provided, comprising:

[0008] The first pitch changing device includes a first pitch changing material loading mechanism and a first translation mechanism. The first pitch changing material loading mechanism is disposed on the first translation mechanism. The first pitch changing material loading mechanism drives the material on it to be arranged with a pitch change along a first direction. The first translation mechanism drives the pitch changing material loading mechanism to move along the first direction.

[0009] The second pitch changing device includes a second pitch changing mechanism and a first material loading mechanism. The first material loading mechanism is disposed on the second pitch changing mechanism. The second pitch changing mechanism is located on one side of the first translation mechanism. The second pitch changing mechanism drives the first material loading mechanism to change pitch along the second direction.

[0010] The third pitch-changing device includes a second translation mechanism, a third pitch-changing mechanism and a second loading mechanism. The second translation mechanism is located on one side of the second pitch-changing mechanism. The second translation mechanism drives the third pitch-changing mechanism to move along the second direction. The second loading mechanism is located on the third pitch-changing mechanism. The third pitch-changing mechanism drives the second loading mechanism to change pitch along the second direction.

[0011] The transfer robot is located between the first pitch-changing device and the second pitch-changing device. The transfer robot transfers the material on the first pitch-changing loading mechanism to the second loading mechanism and the third loading mechanism respectively.

[0012] The tray changing device, located on one side of the third pitch changing device, is used to provide empty trays and collect full trays;

[0013] A loading robot, mounted on a tray changing device, transfers materials from the second and third loading mechanisms to the tray.

[0014] One of the above technical solutions has at least one of the following advantages or beneficial effects: The equipment, through the first variable-pitch loading mechanism in the first variable-pitch device, can drive the material to achieve variable-pitch arrangement along the first direction. Simultaneously, the first translation mechanism can drive the variable-pitch loading mechanism to move along the first direction, further coordinating with the variable-pitch operation, so that the arrangement spacing of the material in the first direction can be precisely adjusted according to predetermined requirements. The second variable-pitch mechanism in the second variable-pitch device can drive the first loading mechanism to achieve variable-pitch arrangement along the second direction, realizing precise control of the material spacing in the second direction. The third variable-pitch mechanism in the third variable-pitch device can also drive the second loading mechanism to achieve variable-pitch arrangement along the second direction, further ensuring that the arrangement spacing of the material in the second direction meets specific production requirements. This multi-directional, multi-stage variable-pitch arrangement setting enables materials such as plastic cigarette holders to achieve a precise and orderly arrangement before tray loading, laying the foundation for efficient and accurate tray loading subsequently. A transfer robot is positioned between the first and second pitch-changing devices. It automatically transfers materials that have undergone initial pitch-changing arrangement on the first pitch-changing loading mechanism to the second and third loading mechanisms, achieving automated connection and transfer of materials between different pitch-changing devices without manual intervention. This significantly improves material transfer efficiency and reduces errors and delays that may be caused by manual operation. A tray-loading robot on the tray-changing device accurately and efficiently transfers materials that have completed pitch-changing arrangement on the second and third loading mechanisms to the tray, realizing automated continuous operation of the entire process from material pitch-changing arrangement to final tray loading. The entire process does not require frequent interruptions for manual tray changing or manual material transfer, effectively improving the production efficiency and quality of plastic cigarette holder tray loading, and reducing production costs and labor intensity.

[0015] In some possible implementations, a first variable-pitch loading mechanism is used to receive 64 plastic cigarette holders, a transfer robot is used to pick up 64 plastic cigarette holders, transfer 48 plastic cigarette holders to a second loading mechanism, and transfer 16 plastic cigarette holders to a third loading mechanism.

[0016] In some possible implementations, when the number of plastic cigarette holders on the third feeding mechanism is 48, the tray-loading robot picks up the 48 plastic cigarette holders from the third feeding mechanism and transfers them to the tray of the tray-changing device.

[0017] In some possible implementations, the first variable-pitch loading mechanism includes: a first cylinder, a telescopic linkage structure, a first loading block, and a first positioning fixture. The first loading block has four components and is slidably disposed on the first translation mechanism. The first cylinder has two components and is disposed side by side on the first translation mechanism. The two first cylinders are connected to the first loading block through the telescopic linkage structure. The two first cylinders drive the multiple first loading blocks to open or close along a first direction. The first positioning fixture has multiple components and is disposed at intervals on the first loading block.

[0018] In some possible implementations, the second material loading mechanism includes: a second material loading block and a second positioning fixture, the second positioning fixture having multiple fixtures spaced apart on the second material loading block, the second material loading block having 12 fixtures movably mounted on a second pitch-changing mechanism, the second pitch-changing mechanism driving the second material loading block to open or close along a second direction.

[0019] In some possible implementations, the third material loading mechanism includes: a third material loading block and a third positioning fixture. The third positioning fixture has multiple fixtures spaced apart on the third material loading block. The third material loading block has 12 pieces and is movably mounted on the third pitch changing mechanism. The third pitch changing mechanism drives the third material loading block to open or close along the second direction.

[0020] In some possible implementations, the transfer robot includes: a dual-axis moving mechanism and a first suction fixture, the first suction fixture being connected to the dual-axis moving mechanism in a transmission manner, the first suction fixture having 64 suction ends, and the dual-axis moving mechanism driving the first suction fixture to move along a second direction and a third direction.

[0021] In some possible implementations, the tray-loading robot includes: a third translation mechanism, a first lifting mechanism, a second lifting mechanism, a second suction fixture, and a third suction fixture. The second suction fixture is drivenly connected to the first lifting mechanism and has 48 suction ends. The third suction fixture is drivenly connected to the second lifting mechanism and has 48 suction ends. The first and second lifting mechanisms are arranged side by side on the third translation mechanism, which is located on the tray-changing device. The third translation mechanism can drive the second and third suction fixtures to move along a first direction.

[0022] In some possible implementations, the disc changing device includes a conveyor channel located along a second direction on one side of the third pitch changing device.

[0023] Secondly, a plastic cigarette holder production system is provided, comprising:

[0024] Injection molding machine;

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] This embodiment provides a plastic cigarette holder production system, including: an injection molding machine, a material handling robot, and a plastic cigarette holder tray loading device.

[0044] Among them, there is an injection molding machine; a material handling robot is installed on the injection molding machine; and a plastic cigarette holder loading device is installed on one side of the injection molding machine. The material handling robot can take out 64 plastic cigarette holders from the injection molding machine and transfer them to the first variable pitch loading mechanism 110 of the plastic cigarette holder loading device.

[0045] Once the injection molding machine completes the injection molding process of the plastic cigarette holders, the injection molding machine opens the mold, and the material handling robot takes out 64 plastic cigarette holders from the injection molding machine and transfers them to the first variable pitch material loading mechanism 110 of the plastic cigarette holder loading equipment.

[0046] like Figure 1 As shown, this embodiment provides a plastic cigarette holder loading device, including: a first pitch changing device 100, a second pitch changing device 200, a third pitch changing device 300, a transfer robot 400, a tray changing device 500, and a loading robot 600.

[0047] In this equipment, the first pitch-changing material-carrying mechanism 110 in the first pitch-changing device 100 can drive the material to achieve pitch-changing arrangement along the first direction. Simultaneously, the first translation mechanism 120 can move the pitch-changing material-carrying mechanism along the first direction, further coordinating with the pitch-changing operation to ensure that the material spacing in the first direction can be precisely adjusted according to predetermined requirements. The second pitch-changing mechanism 210 in the second pitch-changing device 200 can drive the first material-carrying mechanism to achieve pitch-changing arrangement along the second direction, realizing precise control of the material spacing in the second direction. Similarly, the third pitch-changing mechanism 320 in the third pitch-changing device 300 can drive the second material-carrying mechanism 220 to achieve pitch-changing arrangement along the second direction, further ensuring that the material spacing in the second direction meets specific production requirements. This multi-directional, multi-stage pitch-changing arrangement setting enables materials such as plastic cigarette holders to achieve precise and orderly arrangement before tray loading, laying the foundation for efficient and accurate subsequent tray loading. A transfer robot 400 is positioned between the first pitch-changing device 100 and the second pitch-changing device 200. It automatically transfers materials that have undergone initial pitch-changing arrangement on the first pitch-changing loading mechanism 110 to the second loading mechanism 220 and the third loading mechanism 330, respectively. This achieves automated connection and transfer of materials between different pitch-changing devices without manual intervention, greatly improving material transfer efficiency and reducing errors and delays that may be caused by manual operation. A tray-loading robot 600, located on the tray-changing device 500, accurately and efficiently transfers materials that have completed pitch-changing arrangement on the second loading mechanism 220 and the third loading mechanism 330 to the tray, realizing automated continuous operation of the entire process from material pitch-changing arrangement to final tray loading. The entire process does not require frequent interruptions for manual tray changing or manual material transfer, effectively improving the production efficiency and quality of plastic cigarette holder tray loading, and reducing production costs and labor intensity.

[0048] The following is a detailed description of the structure of the plastic cigarette holder loading equipment.

[0049] like Figure 1 As shown, the first pitch changing device 100 includes a first pitch changing material loading mechanism 110 and a first translation mechanism 120. The first pitch changing material loading mechanism 110 is disposed on the first translation mechanism 120. The first pitch changing material loading mechanism 110 drives the material on it to be arranged with a pitch change along a first direction. The first translation mechanism 120 drives the pitch changing material loading mechanism to move along the first direction.

[0050] The structure of the first translation mechanism 120 is not specifically limited. In this embodiment, the first translation mechanism 120 is a cylinder-driven slide structure.

[0051] During operation, the first translation mechanism 120 drives the first variable-pitch loading mechanism 110 to move to the left, bringing it closer to the injection molding machine, facilitating the material handling robot to unload material onto the first variable-pitch loading mechanism 110. The first translation mechanism 120 also drives the first variable-pitch loading mechanism 110 to move to the right, bringing it closer to the transfer robot 400, facilitating the transfer robot 400 to pick up material from the first variable-pitch loading mechanism 110.

[0052] It is worth noting that the first direction corresponds to the X-axis (left-right direction) of the spatial coordinate system, the second direction corresponds to the Y-axis (front-back direction) of the spatial coordinate system, and the third direction corresponds to the Z-axis (up-down direction) of the spatial coordinate system.

[0053] It is worth noting that the first variable-pitch loading mechanism 110 has an open and a retractable state. When the first variable-pitch loading mechanism 110 approaches the injection molding machine, it is in the open state, which corresponds to the material handling robot and facilitates material unloading. When the first variable-pitch loading mechanism 110 approaches the transfer robot 400, it is in the retracted state. This is because, when the transfer robot 400 is gripping products, if the products are too scattered, the stroke of each gripping action of the transfer robot 400 will be longer, and it will need to precisely control multiple gripping points at different locations, which will increase the complexity and time cost of gripping. Furthermore, by using the first variable-pitch loading mechanism 110 to retract and change the pitch of the plastic cigarette holder, the material can be relatively concentrated, reducing the gap between products. In this way, the transfer robot 400 can perform grasping operations within a relatively small area, reducing the travel distance and complexity of the grasping motion. It's like bringing scattered targets together, making it easier and more efficient for the transfer robot 400 to complete grasping tasks. Furthermore, the more compact material layout after the zoom adjustment is beneficial for subsequent transportation, storage, or other operations.

[0054] For example, the robotic arm picks up 64 injection-molded nozzles from the injection molding machine at a time and transfers them to the first variable-pitch loading mechanism 110, where the 64 nozzles are arranged in 4 rows and 16 columns. When the first variable-pitch loading mechanism 110 retracts, the row spacing of this batch of 64 injection-molded nozzles is reduced.

[0055] like Figure 1 As shown, the second pitch changing device 200 includes a second pitch changing mechanism 210 and a first material loading mechanism. The first material loading mechanism is disposed on the second pitch changing mechanism 210. The second pitch changing mechanism 210 is located on one side of the first translation mechanism 120. The second pitch changing mechanism 210 drives the first material loading mechanism to change pitch along the second direction.

[0056] The structure of the second pitch mechanism 210 is not specifically limited. In this embodiment, the second pitch mechanism 210 is a linear motor.

[0057] During operation, the second pitch-changing mechanism 210 controls the first loading mechanism to open, making the spacing between the first loading mechanism and the first pitch-changing loading mechanism 110 partially the same. The transfer robot 400 then picks up a portion of the injection-molded cigarette nozzle from the first pitch-changing loading mechanism 110 and transfers it to the first loading mechanism. The second pitch-changing mechanism 210 then controls the first loading mechanism to close, specifically by controlling it to close backward, thus facilitating the subsequent tray-loading robot 600 to pick it up.

[0058] like Figure 1 As shown, the third pitch-changing device 300 includes a second translation mechanism 310, a third pitch-changing mechanism 320, and a second material-carrying mechanism 220. The second translation mechanism 310 is located on one side of the second pitch-changing mechanism 210. The second translation mechanism 310 drives the third pitch-changing mechanism 320 to move along the second direction. The second material-carrying mechanism 220 is disposed on the third pitch-changing mechanism 320. The third pitch-changing mechanism 320 drives the second material-carrying mechanism 220 to change pitch along the second direction.

[0059] The structure of the second translation mechanism 310 is not specifically limited, and the structure of the third pitch mechanism 320 is not specifically limited. In this embodiment, both the second translation mechanism 310 and the third pitch mechanism 320 are linear motors.

[0060] During operation, the third pitch-changing mechanism 320 controls the second loading mechanism 220 to open, and the second translation mechanism 310 drives the third pitch-changing mechanism 320 to move forward, causing a portion of the third pitch-changing mechanism 320 to be offset from the second pitch-changing mechanism 210. This offset portion is defined as the loading area. The transfer robot 400 grabs another part of the injection-molded cigarette nozzle from the first pitch-changing loading mechanism 110 and transfers it to the second loading mechanism 220. After two grabs, the second translation mechanism 310 drives the third pitch-changing mechanism 320 to move backward, and the third pitch-changing mechanism 320 drives the second loading mechanism 220 to close, facilitating the subsequent tray-loading robot 600 to pick it up.

[0061] The transfer robot 400 is located between the first pitch-changing device 100 and the second pitch-changing device 200. The transfer robot 400 transfers the material on the first pitch-changing loading mechanism 110 to the second loading mechanism 220 and the third loading mechanism 330 respectively.

[0062] The tray changing device 500 is located on one side of the third pitch changing device 300 and is used to provide empty trays and collect full trays.

[0063] A tray loading robot 600 is mounted on a tray changing device. The tray loading robot 600 transfers materials from the second loading mechanism 220 and the third loading mechanism 330 to the tray.

[0064] The working process of this plastic cigarette holder loading equipment is as follows:

[0065] Step 1: The first variable pitch loading mechanism 110 receives 64 plastic cigarette holders in the open state, and then the first variable pitch loading mechanism 110 changes to the closed state.

[0066] In the second step, the second material loading mechanism 220 and the third material loading mechanism 330 are in the open state, and part of the third material loading mechanism 330 is offset from the second material loading mechanism 220;

[0067] The third step involves the transfer robot 400 picking up 64 plastic cigarette holders, transferring 48 of them to the second loading mechanism 220, and transferring 16 of them to the staggered portion of the third loading mechanism 330.

[0068] Fourth step: The second material loading mechanism 220 is moved to the retracted state;

[0069] Step 5: The loading robot 600 removes 48 plastic cigarette holders from the second loading mechanism 220 and transfers them to the changing device 500.

[0070] Step 6: Repeat steps 3 to 5 until the number of plastic mouthpieces on the third feeding mechanism 330 is 48;

[0071] Step 7: When the number of plastic cigarette holders on the third loading mechanism 330 is 48, the loading robot 600 picks up the 48 plastic cigarette holders on the third loading mechanism 330 and transfers them to the material tray of the tray changing device 500.

[0072] Step 8: Repeat the above steps to pack the plastic cigarette holders onto a tray.

[0073] like Figure 2 As shown, in some embodiments, the first variable-pitch loading mechanism 110 includes: a first cylinder 111, a telescopic linkage structure 112, a first loading block 113, and a first positioning fixture 114. The first loading block 113 has four components and is slidably disposed on the first translation mechanism 120. The first cylinder 111 has two components and is disposed side by side on the first translation mechanism 120. The two first cylinders 111 are connected to the first loading block 113 through the telescopic linkage structure 112. The two first cylinders 111 drive the multiple first loading blocks 113 to open or close along a first direction. The first positioning fixture 114 has multiple components and is disposed at intervals on the first loading block 113.

[0074] Two first cylinders 111 drive multiple first material blocks 113 to open or close along a first direction via a telescopic connecting rod structure 112, thus flexibly adjusting the spacing between the material blocks.

[0075] The first material loading block 113 has four slidably mounted on the first translation mechanism 120, which can simultaneously carry multiple materials and improve material loading efficiency.

[0076] like Figure 3 As shown, in some embodiments, the second material loading mechanism 220 includes: a second material loading block 221 and a second positioning fixture 222. The second positioning fixture 222 has multiple fixtures and is spaced apart on the second material loading block 221. The second material loading block 221 has 12 fixtures and is movably mounted on the second pitch mechanism 210. The second pitch mechanism 210 drives the second material loading block 221 to open or close along a second direction.

[0077] There are 48 second positioning fixtures 222 for positioning and placing plastic cigarette holders, wherein each second material block 221 has 4 second positioning fixtures 222.

[0078] In the second loading mechanism 220, the second loading block 221 loads plastic cigarette holders in the open state, which facilitates correspondence with the transfer robot 400. When the second loading block 221 is closed, it loads plastic cigarette holders, which makes it easier for them to be picked up by the subsequent tray loading robot 600 and placed into the tray for orderly arrangement.

[0079] like Figure 4 As shown, in some embodiments, the third material loading mechanism 330 includes: a third material loading block 331 and a third positioning fixture 332. The third positioning fixture 332 has multiple fixtures and is spaced apart on the third material loading block 331. The third material loading block 331 has 12 fixtures and is movably mounted on the third pitch changing mechanism 320. The third pitch changing mechanism 320 drives the third material loading block 331 to open or close along the second direction.

[0080] The third positioning fixture 332 has 48 units for positioning and placing plastic cigarette holders, wherein each third loading block 331 has 4 second positioning fixtures 222.

[0081] In the third loading mechanism 330, the third loading block 331 loads plastic cigarette holders in the open state, which facilitates correspondence with the transfer robot 400. When the third loading block 331 is closed, it loads plastic cigarette holders, which makes it easier for them to be picked up by the subsequent tray loading robot 600 and placed into the tray for orderly arrangement.

[0082] In addition, the plastic cigarette holders in the third loading mechanism 330 are only picked up by the tray loading robot 600 after they are full of 48 pieces. This helps to reduce the number of times the tray loading robot 600 moves and improves its efficiency.

[0083] like Figure 5 As shown, in some embodiments, the transfer robot 400 includes: a dual-axis moving mechanism 410 and a first suction fixture 420. The first suction fixture 420 is connected to the dual-axis moving mechanism 410 in a transmission manner. The first suction fixture 420 has 64 suction ends. The dual-axis moving mechanism 410 drives the first suction fixture 420 to move along a second direction and a third direction.

[0084] The first suction fixture 420 has 64 suction ends, which enables the transfer robot 400 to pick up a large number of plastic cigarette holders at once.

[0085] The dual-axis moving mechanism 410 drives the first suction fixture 420 to move along the second and third directions. This dual-axis moving design allows the transfer robot 400 to be flexibly positioned in a plane. Because the dual-axis moving mechanism 410 can precisely control the position of the first suction fixture 420, combined with 64 suction ends, precise material transfer can be achieved.

[0086] like Figure 1 As shown, in some embodiments, the loading robot 600 includes: a third translation mechanism 610, a first lifting mechanism 620, a second lifting mechanism 630, a second suction fixture 640, and a third suction fixture 650. The second suction fixture 640 is drivenly connected to the first lifting mechanism 620 and has 48 suction ends. The third suction fixture 650 is drivenly connected to the second lifting mechanism 630 and has 48 suction ends. The first lifting mechanism 620 and the second lifting mechanism 630 are arranged side by side on the third translation mechanism 610. The third translation mechanism 610 is located on the tray changing device 500 and can drive the second suction fixture 640 and the third suction fixture 650 to move along a first direction.

[0087] The third translation mechanism 610 can drive the second suction fixture 640 and the third suction fixture 650 to move along the first direction. Combined with the lifting functions of the first lifting mechanism 620 and the second lifting mechanism 630, the tray-loading robot 600 can flexibly move the suction fixtures in three-dimensional space. Furthermore, the first lifting mechanism 620 independently controls the lifting and suction of the second suction fixture 640, and the second lifting mechanism 630 independently controls the lifting and suction of the third suction fixture 650, thereby realizing the transfer of plastic cigarette holders.

[0088] like Figure 1 As shown, in some embodiments, the plate changing device 500 includes a conveying channel 510, which is disposed on one side of the third pitch changing device 300 along a second direction.
