Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and in particular to a rotary clamping mechanism. Background Technology

[0002] In the cigarette production process, it is usually necessary to transport some boxed tobacco accessories (tobacco accessories: carton wrapping paper, box wrapping paper, sealing paper, inner lining paper, and transparent packaging film) through a clamp connected to the execution end of a robotic arm to an AGV trolley. The AGV trolley then delivers the boxed tobacco accessories to different tobacco processing stations. At the different tobacco processing stations, a clamp connected to the execution end of the robotic arm picks up the boxed tobacco accessories loaded on the AGV trolley. Then, the robotic arm moves the boxed tobacco accessories to a temporary tobacco accessory placement position at the processing station, making it convenient for operators to place the tobacco accessories onto the cigarette production machinery later.

[0003] The above-mentioned clamps 1 and 2 are of the same structure. Although clamps 1 and 2 can complete the clamping and releasing process of tobacco auxiliary materials, they also have the following defects in use: 1. The structure of clamps 1 or 2 lacks a mechanism to drive clamps 1 or 2 to rotate to a certain placement angle or a certain clamping angle. When clamping or placing boxed tobacco auxiliary materials in a certain posture, it is inconvenient to clamp or place them, which indirectly affects the unloading process of boxed tobacco auxiliary materials; 2. The structure of clamps 1 or 2 has two cylinders that drive the clamp arms (the first cylinder is connected to the first clamp arm, and the second cylinder is connected to the second clamp arm), which not only increases the overall weight of clamps 1 or 2, but also indirectly increases the load on the robotic arm connected to clamps 1 or 2.

[0004] Therefore, it is necessary to improve the structure of the existing clamp one or clamp two for gripping or releasing boxed tobacco accessories, in order to solve the problems of the lack of a mechanism to drive clamp one or clamp two to rotate to a certain placement angle or a certain gripping angle, which makes it inconvenient to grip or place boxed tobacco accessories in a certain posture, and the two cylinders in the existing clamp one or clamp two structure, which increase the overall weight of clamp one or clamp two, indirectly increasing the load on the mechanical arm connected to clamp one or clamp two. Summary of the Invention

[0005] The purpose of this invention is to propose a rotary clamping mechanism to solve the problems of the lack of a mechanism to drive clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle in the structure of clamp one or clamp two, which makes it inconvenient to clamp or place boxed tobacco auxiliary materials in a certain posture, and the two cylinders in the existing clamp one or clamp two structure, which increase the overall weight of clamp one or clamp two, indirectly increasing the load on the mechanical arm connected to clamp one or clamp two.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A rotary clamping mechanism includes a rotary drive component, a support base, a rotary limiting disc, a telescopic drive component, and gripper assemblies. The surface of the rotary drive component is connected to the top of the support base via a connecting seat. The piston rod of the rotary drive component is rotatably connected to the middle of the support base. A rotary limiting disc is sleeved on the piston rod located between the rotary drive component and the support base. The rotary limiting component and the rotary limiting disc are in motion and limited. The surface of the rotary limiting component is connected to the surface of the support base. The other end of the piston rod of the rotary drive component is connected to the surface of the telescopic drive component located below the support base. The driving end of the telescopic drive component is connected to the surface of two gripper assemblies respectively.

[0008] Furthermore, the rotating limiting disk includes a turntable and stops; the turntable is located between the rotating drive and the support base, the through hole in the middle of the turntable is sleeved with the piston rod of the rotating drive, and at least two stops are provided or threadedly connected to the outer wall of the turntable. Several threaded holes threadedly connected to the stops are provided along the outer wall of the turntable, and the stops respectively move and limit the rotation limiting component.

[0009] Furthermore, the two blocks are spaced apart along the outer wall of the turntable.

[0010] Furthermore, there are two rotation limiting components, which are symmetrically arranged about the support base. The two rotation limiting components are respectively in contact with and limited by the stop blocks provided on the surface of the turntable.

[0011] Furthermore, the rotation limiting component includes a support and a limiting post; the stop block provided on the surface of the turntable is in movable contact with the limiting post, the limiting post is provided at one end of the support near the turntable, and the other end of the support is connected to the surface of the support base.

[0012] Furthermore, the rotary drive component is a rotary cylinder, and the other end of the piston rod of the rotary cylinder is connected to the surface wall of the telescopic drive component located below the support base.

[0013] Furthermore, the telescopic drive component is a double-acting cylinder, the surface of which is connected to the other end of the piston rod of the rotary cylinder, and the drive end of the double-acting cylinder is connected to the surface of the two gripper assemblies respectively.

[0014] Furthermore, the gripper assembly includes an L-shaped drive block and a gripper adjustment component; the inner wall of the L-shaped drive block is connected to the drive end of the double-acting cylinder, and the L-shaped drive block and the gripper adjustment component are threadedly adjustable.

[0015] Furthermore, the gripper adjustment component includes an adjustment bolt with a nut, a gripper arm, and a buffer gripper block; the adjustment bolt with a nut is threadedly connected to an L-shaped drive block, the other end of the adjustment bolt with a nut is connected to the top of the gripper arm, and a buffer gripper block is connected to the inner wall of the gripper arm, the buffer gripper block having an L-shaped structure.

[0016] Furthermore, the gripper assembly also includes a guide block; the inner wall of the guide block is connected to the outer wall of the L-shaped drive block, and a slide bar is provided on the inner wall of the guide block, which is slidably connected to a groove on the outer wall of the gripper arm.

[0017] During operation, when the rotary clamping mechanism is used to load or unload boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories), the outer wall of the rotary drive component in the rotary clamping mechanism is first connected to the execution end of the robotic arm via a bolt assembly. The robotic arm located next to the boxed tobacco accessories then drives the rotary clamping mechanism to move directly above the boxed tobacco accessories. The rotary drive component in the rotary clamping mechanism then drives the gripper assembly to rotate forward to a position that matches the placement posture of the boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories). During the process of the rotary drive component driving the gripper assembly to rotate to a position that matches the placement posture of the boxed tobacco accessories, since the rotary drive component has a piston rod with a rotary limiting plate sleeved on it, the rotary limiting component and the rotary limiting plate move against each other and are limited. Therefore, the rotary limiting plate on the piston rod of the rotary drive component stops rotating when it reaches the position that it abuts against the rotary limiting component. The position where the rotary limiting plate abuts against the rotary limiting component is also the position that matches the placement posture of the boxed tobacco accessories.

[0018] When the rotary drive component in the rotary clamping mechanism rotates the gripper assembly to a position that matches the placement posture of the boxed tobacco accessories, the robotic arm first moves the two open gripper assemblies in the rotary clamping mechanism down to the boxed tobacco accessories, placing the boxed tobacco accessories between the two open gripper assemblies. Then, the telescopic drive component connected to the two gripper assemblies is driven to perform a retraction action, causing the two gripper assemblies to clamp the boxed tobacco accessories. Then, the robotic arm moves the rotary clamping mechanism holding the boxed tobacco accessories to above the AGV trolley. Finally, the telescopic drive component connected to the two gripper assemblies is driven to perform an extension action, causing the two gripper assemblies to separate. The boxed tobacco accessories located between the two gripper assemblies are then unloaded onto the AGV trolley, which then carries the boxed tobacco accessories to the temporary tobacco accessory placement positions at different tobacco processing stations.

[0019] When the AGV trolley brings the boxed tobacco accessories to the temporary placement position for tobacco accessories at different tobacco processing stations, the robotic arm at the temporary placement position first moves the two open gripper assemblies of the rotary clamping mechanism down to the boxed tobacco accessories, placing the boxed tobacco accessories between the two open gripper assemblies. Then, it drives the telescopic drive connected to the two gripper assemblies to retract, causing the two gripper assemblies to clamp the boxed tobacco accessories. Finally, the robotic arm moves the rotary clamping mechanism holding the boxed tobacco accessories to the temporary placement position for tobacco accessories at different tobacco processing stations. Above the placement position, the rotary drive component in the rotary clamping mechanism drives the gripper assembly to rotate in the opposite direction to a position that matches the placement posture of the boxed tobacco accessories. During the process of the rotary drive component driving the gripper assembly to rotate to a position that matches the placement posture of the boxed tobacco accessories, since the rotary drive component has a rotary limiting plate sleeved on its piston rod, the rotary limiting component and the rotary limiting plate move against each other and are limited. Therefore, the rotary limiting plate on the piston rod of the rotary drive component stops rotating when it reaches the position that it abuts against the rotary limiting component. The position where the rotary limiting plate abuts against the rotary limiting component is also the position that matches the placement posture of the boxed tobacco accessories.

[0020] When the rotary drive component in the rotary clamping mechanism drives the gripper assembly to rotate to a position that matches the placement posture of the boxed tobacco accessories, the robotic arm first drives the two open gripper assemblies in the rotary clamping mechanism to move down to the temporary placement position of the tobacco accessories at different tobacco processing stations. Then, the telescopic drive component connected to the two gripper assemblies is driven to extend, causing the two gripper assemblies to separate. The boxed tobacco accessories located between the two gripper assemblies are then unloaded at the temporary placement position of the tobacco accessories at different tobacco processing stations, completing the loading or unloading process of the boxed tobacco accessories.

[0021] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0022] 1. This invention connects the surface of a rotating drive component to the top of a support base via a connecting seat. The piston rod of the rotating drive component is rotatably connected to the center of the support base. A rotating limiting disc is sleeved on the piston rod located between the rotating drive component and the support base. The rotating limiting component and the rotating limiting disc are in motion and limited. The surface of the rotating limiting component is connected to the surface of the support base. The other end of the piston rod of the rotating drive component is connected to a telescopic drive component located below the support base. The driving end of the telescopic drive component is connected to the surface of two gripper assemblies, enabling the rotating clamping mechanism drive component to rotate the gripper assemblies to a position where the boxed tobacco auxiliary materials are placed. During the process of matching the posture, since the piston rod of the rotary drive component is fitted with a rotary limiting disk, the rotary limiting component and the rotary limiting disk move against each other and are limited. Therefore, the rotary limiting disk on the piston rod of the rotary drive component stops rotating when it reaches the position of contact with the rotary limiting component. The position of contact between the rotary limiting disk and the rotary limiting component is also the position that matches the placement posture of the boxed tobacco accessories. This solves the problem that the existing clamp one or clamp two structures lack a mechanism to drive clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle, making it inconvenient to clamp or place boxed tobacco accessories in a certain posture.

[0023] 2. This invention utilizes a rotary clamping mechanism composed of a rotary drive, a support base, a rotary limiting plate, a telescopic drive, a gripper assembly, and a rotary limiting component. During the clamping or releasing of boxed tobacco accessories, only one telescopic drive drives the two gripper assemblies to open or close, thus completing the clamping or releasing of the boxed tobacco accessories. This single telescopic drive not only reduces the overall weight of the rotary clamping mechanism but also reduces the load on the robotic arm connected to it. This solves the problem in existing clamping mechanisms with two cylinders driving the clamping arms, where the increased weight of clamping mechanism one or two indirectly increases the load on the robotic arm connected to clamping mechanism one or two.

[0024] 3. This invention uses a rotary clamping mechanism connected to a robotic arm to load boxed tobacco accessories onto an AGV trolley. The AGV trolley then carries the boxed tobacco accessories to temporary placement positions for tobacco accessories at different tobacco processing stations. At these temporary placement positions, a rotary clamping mechanism connected to another robotic arm unloads the boxed tobacco accessories into the temporary placement positions for tobacco accessories at the different processing stations. This eliminates the need for manual handling by operators and reduces the labor intensity of operators.

[0025] 4. This invention makes the gripper adjustment component in the gripper assembly vertically adjustable. The specific structure of the adjustable gripper adjustment component is that the adjusting bolt with a nut is threadedly connected to the L-shaped drive block, and the other end of the adjusting bolt with the nut is connected to the outer wall of the gripper arm. When the two gripper assemblies are clamping boxed tobacco accessories of different heights, the adjusting bolt threadedly connected to the L-shaped drive block can be turned according to the height of the box containing the tobacco accessories. This causes the gripper arm connected to the other end of the adjusting bolt to move vertically upward or downward to a position that matches the height of the box containing the tobacco accessories, thus satisfying the subsequent clamping of boxed tobacco accessories of different heights by the two gripper assemblies.

[0026] 5. This invention features two stop blocks threaded onto the outer wall of a turntable. Several threaded holes connected to the stop blocks are arranged along the outer wall of the turntable. Each stop block is movable and limited by a rotation limiting component. During the rotation of the clamping mechanism drive to rotate the gripper assembly to different positions matching the placement posture of the boxed tobacco accessories, the stop blocks are threaded onto the outer wall of the turntable corresponding to the various positions. The rotation limiting component then moves and limits the stop blocks installed on the outer wall of the turntable, allowing the clamping mechanism drive to rotate the gripper assembly to various positions matching the placement posture of the boxed tobacco accessories and stop, thus satisfying the need to rotate the gripper assembly to multiple positions matching the placement posture of the boxed tobacco accessories.

Detailed Implementation

[0036] like Figure 1-8 As shown, to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0037] Example

[0038] The existing clamps 1 and 2 have the following defects in the process of gripping or releasing boxed tobacco auxiliary materials: 1. The structure of clamp 1 or clamp 2 has two cylinders on the clamp frame that drive the clamp arms to move closer or further away (two cylinders that drive the clamp arms: the first cylinder is driven to the first clamp arm, and the second cylinder is driven to the second clamp arm). The two cylinders not only increase the overall weight of clamp 1 or clamp 2, but also indirectly increase the load on the mechanical arm connected to clamp 1 or clamp 2.

[0039] Second, the structure of clamp one or clamp two lacks a mechanism to drive clamp one or clamp two to a certain placement angle or a certain clamping angle. When clamping or placing boxed tobacco accessories in different postures, it is inconvenient to clamp or place boxed tobacco accessories in different postures, which indirectly affects the unloading process of boxed tobacco accessories.

[0040] Therefore, this application designs a rotary clamping mechanism to solve the problems of existing clamp one or clamp two structures having two cylinders driving the clamp arms, which indirectly increases the load on the mechanical arm connected to clamp one or clamp two due to the increased overall weight of clamp one or clamp two, and the lack of a mechanism in the structure of clamp one or clamp two to drive clamp one or clamp two to a certain placement angle or a certain clamping angle, making it inconvenient to clamp or place boxed tobacco accessories in a certain posture.

[0041] For details, please refer to Figure 1 and Figure 2A rotary clamping machine includes a rotary drive component 1, a support base 2, a rotary limiting disc 4, a telescopic drive component 5, and a gripper assembly 6. The surface of the rotary drive component 1 is connected to the top of the support base 2 via a connecting seat 9. The piston rod 3 of the rotary drive component 1 is rotatably connected to the middle of the support base 2. The rotary limiting disc 4 is sleeved on the piston rod 3 located between the rotary drive component 1 and the support base 2. The rotary limiting component 19 is in contact with and limited by the rotary limiting disc 4. The surface of the rotary limiting component 19 is connected to the surface of the support base 2. The other end of the piston rod 3 of the rotary drive component 1 is connected to the surface of the telescopic drive component 5 located below the support base 2. The driving end of the telescopic drive component 5 is connected to the surface of the two gripper assemblies 6 respectively.

[0042] In practical applications, when using this rotary clamping mechanism to load or unload boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories), the outer wall of the rotary drive component 1 in the rotary clamping mechanism is first connected to the execution end of the robotic arm via a bolt assembly. The robotic arm, located next to the boxed tobacco accessories, then moves the rotary clamping mechanism to directly above the boxed tobacco accessories. The rotary drive component 1 in the rotary clamping mechanism then drives the gripper assembly 6 to rotate clockwise to a position matching the placement posture of the boxed tobacco accessories. The rotary drive component 1 then drives the gripper assembly 6 to rotate clockwise to a position matching the placement posture of the boxed tobacco accessories. During the process of rotating component 6 to a position that matches the placement posture of the boxed tobacco accessories (boxed tobacco accessories: box containing tobacco accessories), since the piston rod of the rotating drive component 1 is fitted with a rotating limiting disk 4, and the rotating limiting component 19 and the rotating limiting disk 4 are in motion and limited, the rotating limiting disk 4 on the piston rod 3 of the rotating drive component 19 will stop rotating when it reaches the position that abuts against the rotating limiting component 19. The position where the rotating limiting disk 4 abuts against the rotating limiting component 19 is also the position that matches the placement posture of the boxed tobacco accessories.

[0043] When the rotary drive 1 in the rotary clamping mechanism drives the gripper assembly 6 to rotate to a position that matches the placement posture of the boxed tobacco accessories, the robotic arm first drives the two open gripper assemblies 6 in the rotary clamping mechanism to move down to the boxed tobacco accessories, and places the boxed tobacco accessories between the two open gripper assemblies 6. Then, the telescopic drive 5 connected to the two gripper assemblies 6 is driven to perform a retraction action, causing the two gripper assemblies 6 to clamp the boxed tobacco accessories. Then, the robotic arm moves the rotary clamping mechanism holding the boxed tobacco accessories to the top of the AGV trolley. Finally, the telescopic drive 5 connected to the two gripper assemblies 6 is driven to perform an extension action, causing the two gripper assemblies 6 to separate. The boxed tobacco accessories located between the two gripper assemblies 6 are then unloaded onto the AGV trolley, and the AGV trolley takes the boxed tobacco accessories to the temporary tobacco accessory placement position at different tobacco processing stations.

[0044] When the AGV trolley brings the boxed tobacco accessories to the temporary placement position for tobacco accessories at different tobacco processing stations, the robotic arm at the temporary placement position first moves the two open gripper assemblies 6 of the rotary clamping mechanism down to the boxed tobacco accessories, placing the boxed tobacco accessories between the two open gripper assemblies 6. Then, it drives the telescopic drive component 5, which is connected to the two gripper assemblies 6, to retract, causing the two gripper assemblies 6 to clamp the boxed tobacco accessories. Finally, the robotic arm moves the rotary clamping mechanism holding the boxed tobacco accessories above the temporary placement position for tobacco accessories at different tobacco processing stations. The rotary drive 1 in the clamping mechanism then drives the gripper assembly 6 to rotate in the opposite direction to a position that matches the placement posture of the boxed tobacco accessories. During the process of the rotary drive driving the gripper assembly 6 to rotate to a position that matches the placement posture of the boxed tobacco accessories, since the rotary drive 1 has a rotary limiting disk 4 sleeved on the piston rod 3, the rotary limiting component 19 and the rotary limiting disk 4 move against each other and are limited. Therefore, the rotary limiting disk 4 on the piston rod 3 of the rotary drive 19 stops rotating when it reaches the position that abuts against the rotary limiting component 19. The position where the rotary limiting disk 4 abuts against the rotary limiting component 19 is also a position that matches the placement posture of the boxed tobacco accessories.

[0045] When the rotary drive 1 in the rotary clamping mechanism drives the gripper assembly 6 to rotate to a position that matches the placement posture of the boxed tobacco accessories, the robotic arm first drives the two open gripper assemblies 6 in the rotary clamping mechanism to move down to the temporary placement position of the tobacco accessories at different tobacco processing stations. Then, the telescopic drive 5 connected to the two gripper assemblies 6 is driven to extend, causing the two gripper assemblies 6 to separate. The boxed tobacco accessories located between the two gripper assemblies 6 are then unloaded at the temporary placement position of the tobacco accessories at different tobacco processing stations, completing the loading or unloading process of the boxed tobacco accessories.

[0046] In the process of loading or unloading boxed tobacco accessories using the rotary clamping mechanism described above, only one telescopic drive component 5 drives the two gripper assemblies 6 to open or close, thereby completing the gripping or releasing of the boxed tobacco accessories. Thus, the telescopic drive component 5 in the rotary clamping mechanism structure not only reduces the overall weight of the rotary clamping mechanism but also indirectly reduces the load on the robotic arm connected to the rotary clamping mechanism. Furthermore, during the process of the rotary clamping mechanism's drive component 1 rotating the gripper assemblies 6 to a position matching the placement posture of the boxed tobacco accessories, due to the characteristics of the rotary drive component 1... A rotating limiting disk 4 is sleeved on the piston rod. The rotating limiting member 19 moves against the rotating limiting disk 4 and is limited. When the rotating limiting disk 4 on the piston rod 3 of the rotating drive member 19 rotates to the position where it abuts against the rotating limiting member 19, it stops rotating. The position where the rotating limiting disk 4 abuts against the rotating limiting member 19 is also a position that matches the placement posture of the boxed tobacco accessories. This solves the problem that the existing clamp one or clamp two structures lack a mechanism to drive the clamp one or clamp two to rotate to a certain placement angle or a certain clamping angle, making it inconvenient to clamp or place boxed tobacco accessories in a certain posture.

[0047] Please see Figure 1 , Figure 3 and Figure 4 The rotating limiting disk 4, which is in active contact with the rotating limiting member 19, includes a turntable 7 and a stop block 8. The turntable 7 is used to engage with the piston rod 3 of the rotating drive member 1 so that the rotating piston rod 3 drives the turntable 7 to rotate. The stop block 8 is used to connect with the outer wall of the turntable 7 so that the rotating turntable 7 causes the stop block 8 to rotate to the rotating limiting member 19 to engage with the limiting position.

[0048] Specifically, the disc-shaped turntable 7 is located between the rotary drive component 1 and the L-shaped support base 2. There is a certain gap between the disc-shaped turntable 7 and the two L-shaped support bases 2 to prevent rotational interference between the disc-shaped turntable 7 and the two L-shaped support bases 2 when the disc-shaped turntable 7 rotates. A through hole is also opened in the middle of the disc-shaped turntable 7. The through hole is sleeved with the piston rod 3 of the rotary drive component 1. At least two columnar stops 8 are provided on the outer wall of the turntable 7. The two columnar stops 8 are arranged at intervals along the outer wall of the disc-shaped turntable 7. The columnar stops 8 respectively move and abut against the rotation limiting component 19 for limitation. There are two rotation limiting components 19. The two rotation limiting components 19 are symmetrically arranged about the support base 2. The two rotation limiting components respectively cooperate with the two stops 8 provided on the surface wall of the turntable 7 for limitation.

[0049] In practical application, when the rotary drive 1 drives the two gripper assemblies 6 to rotate to a gripping position that matches the placement posture of the boxed tobacco accessories, the rotary drive 1 will drive the turntable 7 with the stop block 8 and the two gripper assemblies 6 connected to the drive end of the telescopic drive 5 to rotate forward via the piston rod 3. During this rotation, one of the stop blocks 8 on the turntable 7 will abut against the rotation limiter 19 and be limited. At this time, the turntable 7, the piston rod 3 sleeved with the turntable 7, and the two gripper assemblies 6 connected to the drive end of the telescopic drive 5 will stop rotating. Since the stop block 8 that abuts against the rotation limiter 19 is located on the outer wall of the turntable 8, the rotary drive 1 drives the two gripper assemblies 6 to rotate to a gripping position that matches the placement posture of the boxed tobacco accessories. Thus, the process of the rotary drive 1 driving the two gripper assemblies 6 to rotate to a gripping position that matches the placement posture of the boxed tobacco accessories is completed.

[0050] When the rotary drive 1 drives the two gripper assemblies 6 to rotate to a release position that matches the placement posture of the boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories), the rotary drive 1 will drive the turntable 7 with the stop block 8 and the two gripper assemblies 6 connected to the drive end of the telescopic drive 5 to rotate in the opposite direction via the piston rod 3. During this rotation, another stop block 8 on the turntable 7 will abut against another rotation limiter 19 and be limited. At this time, the turntable 7, the piston rod 3 sleeved with the turntable 7, and the two gripper assemblies 6 connected to the drive end of the telescopic drive 5 will stop rotating. Since the other stop block 8 that abuts against another rotation limiter 19 is located on the outer wall of the turntable 8, the rotary drive 1 drives the two gripper assemblies 6 to rotate to a release position that matches the placement posture of the boxed tobacco accessories, thus completing the process of the rotary drive 1 driving the two gripper assemblies 6 to rotate to a release position that matches the placement posture of the boxed tobacco accessories and stopping.

[0051] It should be noted that, in order to prevent the stop block 8 on the turntable 7 from interfering with the rotation of the L-shaped support 2, a certain gap is reserved between the stop block 8 and the L-shaped support 2.

[0052] In this example, to meet the requirement that the rotary drive 1 drives the two gripper assemblies 6 to rotate to different gripping / releasing positions that match the placement posture of the boxed tobacco auxiliary materials, the connection between the disc-shaped turntable 7 and the columnar stop 8 can also be as follows: the outer wall of the disc-shaped turntable is threaded with the columnar stop 8, and several threaded holes that are threaded to the columnar stop 8 are arranged at intervals along the outer wall of the disc-shaped turntable 7, and the columnar stop 8 is respectively in contact with and limited by the rotation limiter 19.

[0053] In practical applications, during the process of the rotary clamping mechanism drive 1 driving the gripper assembly 6 to rotate to different positions that match the placement posture of the boxed tobacco accessories, a stop block 8 can be threaded onto the outer wall of the turntable 7 corresponding to the various positions that the rotary clamping mechanism drive 1 drives the gripper assembly 6 to match the placement posture of the boxed tobacco accessories. Then, in conjunction with the rotary limiting component 19, the stop block 8 threaded onto the outer wall of the turntable 7 is moved to abut and limited. The rotary clamping mechanism drive then drives the gripper assembly 6 to rotate to various positions that match the placement posture of the boxed tobacco accessories and stops, thus satisfying the need to rotate the gripper assembly to various positions that match the placement posture of the boxed tobacco accessories.

[0054] Please see Figure 1 , Figure 2 and Figure 4 The rotating limiting member 4, which abuts against and limits the stop block 8 on the outer wall of the disc-shaped turntable 7, includes a support 10 and a limiting post 11. The support 10 is used to detachably connect with the support base 2 and to serve as a base for installing the limiting post 11. The limiting post 11 is used to abut against and limit the stop block 8 on the outer wall of the turntable 7.

[0055] Specifically, the columnar stop 8 on the outer wall of the disc-shaped turntable 7 is in active contact with the columnar limiting post 11. The columnar limiting post 11 is located between the rotary drive component 1 and the support base 2. The columnar limiting post 11 is located at one end of the support 10 near the turntable 7, and the other end of the support 10 is connected to the surface wall of the support base 2.

[0056] In practical application, when the stop block 8 on the outer wall of the turntable 7 comes into contact with the rotation limiting member 4, the piston rod 3 of the rotation drive member 1 drives the turntable 7 to rotate circumferentially. The circumferentially rotating turntable rotates to the position of the limiting post 11 set on the support 10, and the stop block 8 on the outer wall of the turntable 7 comes into contact with the columnar limiting post 11, thus completing the process of the stop block 8 on the outer wall of the turntable 7 and the limiting post 11 moving and abutting and limiting.

[0057] It should be noted that when the stop block 8 on the outer wall of the turntable 7 abuts against the limiting post 11, in order to prevent the stop block 8 from rigidly contacting the limiting post 11, rubber sleeves are respectively fitted on the ends of the stop block 8 and the limiting post 11, and the contours of the rubber sleeves are respectively matched to the ends of the stop block 8 and the limiting post 11.

[0058] Please see Figure 5The rotary drive component 1, which is used to drive the piston rod 3, the rotary limiting disk 4, the telescopic drive component 5, and the two gripper assemblies 6 connected to the telescopic drive component 5 to rotate, is a rotary cylinder. Specifically, the surface wall of the rotary cylinder is connected to the top of the support base 2 through the connecting seat 9. The piston rod 3 of the rotary cylinder 1 is rotatably connected to the middle of the support base 2. The rotary limiting disk 4 is sleeved on the piston rod 3 located between the rotary cylinder 1 and the support base 2. The other end of the piston rod 3 of the rotary cylinder 1 is connected to the telescopic drive component 5 located below the support base 2. The driving end of the telescopic drive component 5 is connected to the surface wall of the two gripper assemblies 6 respectively.

[0059] In practical applications, when the rotary cylinder drives the piston rod 3, the rotary limiting plate 4, the telescopic drive component 5, and the two gripper assemblies 6 connected to the telescopic drive component 5 to rotate, the rotary cylinder can be driven to rotate the piston rod 3. The rotary limiting plate 4, the telescopic drive component 5, and the two gripper assemblies 6 connected to the telescopic drive component 5 will then rotate accordingly, so that the two gripper assemblies 6 rotate to a position that matches the placement posture of the boxed tobacco accessories, making it easier for the two gripper assemblies 6 to subsequently grip the box containing the tobacco accessories.

[0060] Please see Figure 5 The telescopic drive 5 used to drive the two gripper assemblies 6 to open or close is a double-acting cylinder. The surface of the double-acting cylinder is connected to the other end of the piston rod 3 of the rotary cylinder. The driving end of the double-acting cylinder is connected to the surface of the two gripper assemblies 6 respectively.

[0061] In practical applications, when the double-acting cylinder drives the two gripper assemblies 6 to clamp the boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories), the double-acting cylinder can be driven to move. The two piston rods at the two opposite ends of the double-acting cylinder will pull the two gripper assemblies 6 closer to each other, clamping the boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories) that have been placed between the two gripper assemblies 6 in advance, so as to complete the process of using the telescopic drive 5 to drive the two gripper assemblies 6 to clamp the boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories).

[0062] When the double-acting cylinder releases the boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories) held between the two gripper assemblies 6, it can drive the double-acting cylinder to move. The two piston rods at the two opposite ends of the double-acting cylinder push the two gripper assemblies 6 away from each other, and the boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories) held between the two gripper assemblies 6 will fall down, thus completing the process of releasing the boxed tobacco accessories (boxed tobacco accessories: boxes containing tobacco accessories) held between the two gripper assemblies 6 by the telescopic drive 5.

[0063] It should be noted that the double-acting cylinder is existing technology, and no improvements or designs have been made to it; therefore, its structure will not be described in detail.

[0064] Please see Figure 5 , Figure 6 , Figure 7 To grip boxes of different heights containing tobacco accessories, the gripper assembly 6 includes an L-shaped drive block 12 and a gripper adjustment component 13. The L-shaped drive block 12 serves as a medium for connecting the double-acting cylinder and the gripper adjustment component 13, so that the gripper adjustment component 13 moves with the double-acting cylinder. The gripper adjustment component 13 is used to be adjustablely connected to the cross arm thread in the L-shaped drive block 12 to meet the needs of gripping boxes of different heights containing tobacco accessories.

[0065] Specifically, the vertical arm of the L-shaped drive block 12 is connected to the drive end of the double-acting cylinder, and the middle part of the horizontal arm of the L-shaped drive block 12 is adjustablely connected to the gripper adjustment member 13.

[0066] In practical applications, when clamping boxes of different heights containing tobacco accessories, the clamping adjustment component 13, which is adjustable to the middle of the horizontal arm in the L-shaped drive block 12, can be adjusted according to the different heights of the boxes containing tobacco accessories. This allows the clamping adjustment component 13 to move vertically upwards or downwards to a position that matches the height of the box containing tobacco accessories. Then, the double-acting cylinder is driven to move the two adjusted clamping adjustment components 13 closer together to clamp the box containing tobacco accessories between the two clamping adjustment components 13, thus completing the process of clamping boxes of different heights containing tobacco accessories.

[0067] It should be noted that, to prevent over-clamping by the two gripper adjustment components 13, a threaded hole (not shown in the figure) can be provided on the surface wall of the vertical arm of each L-shaped drive block 12 facing the drive end of the double-acting cylinder. The threaded hole is threadedly and adjustablely connected to the threaded limit post, and the threaded limit post is in movable limit contact with the surface wall of the drive end of the double-acting cylinder. For example, the length of the threaded limit post can be adjusted to determine the clamping position of the tobacco auxiliary material box by the two gripper adjustment components 13. This not only prevents over-clamping by the two gripper adjustment components 13, but also allows for adjustment of the clamping position of the tobacco auxiliary material box with different widths by the two gripper adjustment components 13.

[0068] Please see Figure 6 , Figure 7 and Figure 8The gripper adjustment component 13, which is adjustablely connected to the cross arm in the L-shaped drive block 12, includes an adjustment bolt 14 with a nut, a gripper arm 15, and a buffer gripper block 16. The adjustment bolt 14 with a nut is threadedly connected to the threaded hole on the cross arm in the L-shaped drive block 12 so that the adjustment bolt 14 can be adjusted to move vertically. The gripper arm 15 is connected to the adjustment bolt 14 so that the vertically adjustable adjustment bolt 14 can drive the gripper arm 15 to move vertically. The buffer gripper block 16 is connected to the inner wall of the gripper arm 15 to clamp and protect the box containing tobacco accessories.

[0069] Specifically, the adjusting bolt 14 with a nut is threadedly connected to the threaded through hole on the cross arm of the L-shaped drive block 12, and the other end of the adjusting bolt 14 with a nut is connected to the top of the gripper arm 15. The inner wall of the gripper arm 15 is connected to a buffer claw block 16, which has an L-shaped structure.

[0070] In practical applications, when adjusting the gripper adjustment component 13, the adjusting bolt 14 connected to the threaded through hole on the horizontal arm of the L-shaped drive block 12 can be turned. The gripper arm 15 connected to the other end of the adjusting bolt 14 will then move vertically upward or downward to a position that matches the height of the box containing tobacco auxiliary materials, thus completing the process of adjusting the gripper adjustment component 13.

[0071] Please see Figure 7 In order to make the gripper arm 15 in the gripper adjustment component 13 move more smoothly downward or upward in the vertical direction during the adjustment of the gripper adjustment component 13, the gripper assembly 6 also includes a rectangular guide block 17.

[0072] Specifically, the inner wall of the rectangular guide block 17 is connected to the outer wall of the L-shaped drive block 12. The inner wall of the rectangular guide block 17 is provided with a slide bar, which is slidably connected to the slide groove 18 on the outer wall of the gripper arm 15.

[0073] In practical applications, when the adjusting bolt 14 connected to the threaded through hole on the horizontal arm of the L-shaped drive block 12 is turned, the gripper arm 15 connected to the other end of the adjusting bolt 14 moves vertically upward or downward. Since the inner wall of the rectangular guide block 17 is provided with a slide bar, and the slide bar is slidably connected to the slide groove 18 on the outer wall of the gripper arm 15, on the one hand, the gripper arm 15 moves more smoothly downward or upward in the vertical direction, and on the other hand, it provides guidance for the gripper arm 15 moving downward or upward in the vertical direction.
