Description

TECHNICAL FIELD

[0001] The utility model relates to robot design technical field, in particular to a turnover machine. BACKGROUND

[0002] In industrial manufacturing production, material often needs to be turned over. Taking the paperboard transmission of a packaging box as an example, in some scenarios, the paperboard needs to be turned over after entering the conveyor belt to adapt to the next processing procedure.

[0003] Most of the traditional turnover machines are independent devices from the conveyor belt. The material needs to be separated from the conveyor belt (for example, the material is transferred from the conveyor belt to the feeding station of the turnover machine by a mechanical hand), enters the range of the clamping jaw of the turnover machine, and then the material is grabbed and turned over by 180 degrees by the clamping jaw, and then the material is put back into the conveyor belt. The traditional design has a complex process, low operation smoothness, and low work efficiency. UTILITY MODEL CONTENT

[0004] Therefore, the utility model provides a turnover machine which integrates the turnover module and the conveying module, sends the material into the turnover clamp by the conveyor belt, and the turnover clamp completes the turnover action in the same direction as the conveying direction of the conveyor belt on the conveyor belt, so that the material is returned to the conveyor belt again after completing the turnover to complete the discharging, the process is simple, the operation smoothness is high, and the work efficiency is high.

[0005] A turnover machine comprises:

[0006] a conveying module; the conveying module comprises: a plurality of conveying belts arranged side by side; an active gap is arranged between two adjacent conveying belts; and

[0007] a turnover module arranged adjacent to the conveying module; the turnover module comprises: a crossbeam on the conveying belt, a turnover driver connected to the crossbeam, and a plurality of turnover clamps mounted on the crossbeam side by side; the arrangement direction of the crossbeam is orthogonal to the conveying direction of the conveying belt; the installation position of the turnover clamp corresponds to the active gap one by one; and the orientation of the turnover clamp is arranged in line with the conveying direction of the conveying belt.

[0008] In the aforementioned turning machine, when material enters the conveyor belt, it is conveyed to the turning fixture and enters the gripping range of the fixture. The turning fixture then clamps the material. Next, the turning driver drives the crossbeam to rotate 180°, causing the turning fixture to rotate 180° with the material to complete the turning. Simultaneously, the material returns to the conveyor belt for output. This design integrates the turning module and the conveyor module. The conveyor belt feeds the material into the turning fixture, which performs the turning action on the conveyor belt in the same direction as the conveyor belt, allowing the material to return to the conveyor belt for discharge. The process is simple, the operation is smooth, and the work efficiency is high.

[0009] In one embodiment, the flipping clamp includes: a base connecting to the crossbeam, a first clamping finger slidingly connected to the base, a second clamping finger slidingly connected to the base, and a clamping driver respectively connecting the first and second clamping fingers; the first and second clamping fingers are parallel to each other and both are configured corresponding to the movable gap; the clamping driver is used to drive the first and / or second clamping fingers to clamp the material. The movable semicircular range of the first and second clamping fingers is coplanar with the movable gap, ensuring the flexibility of the first and second clamping fingers without hindering the operation of the conveyor belt.

[0010] In one embodiment, the base is provided with a stop plate; the stop plate is vertically disposed between the first and second clamping fingers. The stop plate is used to intercept material and also serves an alignment function.

[0011] In one embodiment, the flipping fixture further includes: a scissor-type telescopic arm mounted on a base; the middle portion of the scissor-type telescopic arm is fixedly connected to the base; a first clamping finger is mounted on one end of the scissor-type telescopic arm, and a second clamping finger is mounted on the other end of the scissor-type telescopic arm; the first or second clamping finger is connected to a clamping driver. During operation, the clamping driver drives one end of the scissor-type telescopic arm, causing the other end of the scissor-type telescopic arm to move synchronously. Therefore, while achieving the same opening amplitude, the stroke of the clamping driver can be halved, resulting in a faster response speed and higher working efficiency for the flipping fixture.

[0012] In one embodiment, the flipping fixture further includes a linear guide rail mounted on a base; both the first and second gripping fingers are slidably mounted on the linear guide rail. The linear guide rail can improve the movement accuracy and stability of the first and second gripping fingers.

[0013] In one embodiment, the clamping actuator is a linear telescopic cylinder. Linear telescopic cylinders are simple in structure, low in cost, and easy to operate.

[0014] In one embodiment, the turning machine further includes: a frame connecting the conveyor module and the turning module respectively; the frame is equipped with a feeding sensor, a clamping sensor, a releasing sensor, and a discharging sensor; the feeding sensor is located at the feeding end of the conveyor belt, the clamping sensor is located at the zero position of the turning fixture, the releasing sensor is located at the 180° flip position of the turning fixture, and the discharging sensor is located at the discharging end of the conveyor belt; the feeding sensor and the discharging sensor are electrically connected to the conveyor module respectively; the clamping sensor and the releasing sensor are electrically connected to the turning module respectively. Automated operation of the conveyor module and the turning module can be achieved through multiple sensors.

[0015] In one embodiment, the tilting actuator includes a speed reducer connected to one end of the crossbeam and a rotary motor connected to the speed reducer. The speed reducer can increase the output torque of the rotary motor, thereby driving the crossbeam to tilt more efficiently. Attached Figure Description

[0035] like Figures 1 to 8 As shown, it is a dough-turning machine 100 according to one embodiment of the present utility model.

[0036] like Figure 1 and Figure 2 As shown, the flipping machine 100 includes a conveying module 10 and a flipping module 20 disposed adjacent to the conveying module 10. The conveying module 10 is used to convey materials that need to be flipped, and the flipping module 20 is used to flip the materials located on the conveying module 10 and return the materials to the conveying module 10 while completing the flipping process.

[0037] The following text, combined with Figures 1 to 8 As shown, the above-mentioned dough-turning machine 100 will be further explained.

[0038] like Figure 3 and Figure 4As shown, the conveying module 10 includes multiple conveyor belts 11 arranged side by side. An movable gap 12 is provided between adjacent conveyor belts 11. In this embodiment, the conveying module 10 has sixteen conveyor belts 11, divided into two equal groups with the flipping module 20 as the dividing line. Conveyor belts 11 located in the same group are driven by the same motor.

[0039] like Figure 3 and Figure 4 As shown, the flipping module 20 includes: a crossbeam 21 located on the conveyor belt 11, a flipping driver 22 connected to the crossbeam 21, and a plurality of flipping clamps 23 mounted side by side on the crossbeam 21. The orientation of the crossbeam 21 is orthogonal to the conveying direction of the conveyor belt 11. The installation positions of the flipping clamps 23 correspond one-to-one with the movable gaps 12. The orientation of the flipping clamps 23 is collinear with the conveying direction of the conveyor belt 11. For example, in this embodiment, the flipping module 20 has five flipping clamps 23, each flipping clamp 23 being located at one movable gap 12.

[0040] In this solution, the specific form of the flipping fixture 23 is not limited as long as it can grasp the material.

[0041] For example, such as Figure 5 and Figure 6 As shown, in this embodiment, the flipping clamp 23 includes: a base 231 connecting the crossbeam 21, a first clamping finger 232 slidingly connected to the base 231, a second clamping finger 233 slidingly connected to the base 231, and a clamping driver 234 respectively connecting the first clamping finger 232 and the second clamping finger 233. The first clamping finger 232 and the second clamping finger 233 are parallel to each other and are both arranged corresponding to the movable gap 12. The clamping driver 234 is used to drive the first clamping finger 232 and / or the second clamping finger 233 to move to clamp the material. The semi-circular range of the first clamping finger 232 and the second clamping finger 233 is coplanar with the movable gap 12, ensuring the flexibility of the first clamping finger 232 and the second clamping finger 233 without hindering the operation of the conveyor belt 11.

[0042] Furthermore, such as Figure 5 As shown, the base 231 may be provided with a stop plate 2311. The stop plate 2311 is vertically disposed between the first clamping finger 232 and the second clamping finger 233. The stop plate 2311 is used to intercept materials and also serves an alignment function.

[0043] In order to enable the flipping fixture 23 to complete the flipping process efficiently, the flipping fixture 23 can be improved.

[0044] For example, such as Figure 7 and Figure 8As shown, the flipping clamp 23 may further include a scissor-type telescopic arm 235 mounted on the base 231. The middle part of the scissor-type telescopic arm 235 is fixedly connected to the base 231 (e.g., Figure 7 Point A (marked) is fixedly connected to base 231. First clamping finger 232 is installed at one end of scissor lift 235, and second clamping finger 233 is installed at the other end of scissor lift 235. First clamping finger 232 or second clamping finger 233 is connected to clamping actuator 234 (e.g., ...). Figure 8 As shown in this embodiment, the second gripper finger 233 is connected to the gripper driver 234. During operation, the gripper driver 234 drives one end of the scissor-type telescopic arm 235 to move, which causes the other end of the scissor-type telescopic arm 235 to move synchronously. Therefore, under the premise that the flipping fixture 23 achieves the same opening amplitude, the stroke of the gripper driver 234 can be halved, the flipping fixture 23 has a faster response speed and higher working efficiency.

[0045] Based on the scissor lift telescopic boom 235, the clamping actuator 234 can be a linear telescopic cylinder. Linear telescopic cylinders have a simple structure, low cost, and are easy to operate.

[0046] In other embodiments, without using a scissor-type telescopic arm 235 or other transmission components for achieving synchronous action, the clamping driver 234 can also be a finger-clamping cylinder, which can also achieve the effect of driving the first clamping finger 232 and the second clamping finger 233 to move closer to each other or further apart synchronously.

[0047] It should be noted that in other embodiments, one of the first gripping finger 232 and the second gripping finger 233 can be set as a stationary gripping finger, while the other is a movable gripping finger, which can also achieve the purpose of gripping materials.

[0048] In addition, to improve the stability and accuracy of the flipping fixture 23's movement, such as... Figure 7 As shown, the flipping fixture 23 may further include a linear guide rail 236 mounted on the base 231. The first gripper 232 and the second gripper 233 are both slidably mounted on the linear guide rail 236. The linear guide rail 236 can improve the movement accuracy and stability of the first gripper 232 and the second gripper 233.

[0049] like Figure 3 As shown, in this embodiment, the tilting drive 22 includes a reducer 221 connected to one end of the crossbeam 21 and a rotary motor 222 connected to the reducer 221. The reducer 221 can increase the output torque of the rotary motor 222, which can drive the crossbeam 21 to tilt more efficiently.

[0050] Brief description of working principle:

[0051] like Figure 3 andFigure 4 As shown, before the material is placed onto the conveyor belt 11, the flipping clamp 23 is in the zero position. At this time, the flipping clamp 23 is collinear with the conveyor belt 11 in the conveying direction, and the opening of the flipping clamp 23 is opposite to the material's forward direction. During operation, when the material enters the conveyor belt 11, it is conveyed to the flipping clamp 23 and enters its gripping range. Then, the flipping clamp 23 clamps the material. Next, the flipping driver 22 drives the crossbeam 21 to rotate 180°, causing the flipping clamp 23 to rotate 180° with the material to complete the flipping. Simultaneously, the material returns to the conveyor belt 11 and is output via the conveyor belt 11. When the material leaves the gripping range of the flipping clamp 23, the flipping driver 22 drives the crossbeam 21 to rotate 180° in the opposite direction to reset.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, the flipping machine 100 may further include a frame 30 that connects the conveyor module 10 and the flipping module 20 respectively. The frame 30 is equipped with a feed sensor 31, a clamping sensor 32, a discharge sensor 33, and a discharge sensor 34. The feed sensor 31 is located at the feed end of the conveyor belt 11, the clamping sensor 32 is located at the zero position of the flipping fixture 23, the discharge sensor 33 is located at the 180° flip position of the flipping fixture 23, and the discharge sensor 34 is located at the discharge end of the conveyor belt 11. The feed sensor 31 and the discharge sensor 34 are electrically connected to the conveyor module 10. The clamping sensor 32 and the discharge sensor 33 are electrically connected to the flipping module 20. Automated operation of the conveyor module 10 and the flipping module 20 can be achieved through multiple sensors. For example, when the feed sensor 31 detects that material has entered the conveyor belt 11, the conveyor belt 11 starts working to receive the material and convey it to the flipping clamp 23. When the material enters the gripping range of the flipping clamp 23 and has reached the preset position, the flipping clamp 23 clamps the material, and the crossbeam 21 flips backward 180°. When the discharge sensor 33 detects that the material has reached the preset position where the flipping is completed, the flipping clamp 23 releases the material, and then the material returns to the conveyor belt 11 and is carried back and forth. When the discharge sensor 34 detects that the material has left, the conveyor belt enters standby mode.

[0053] The aforementioned turning machine 100 integrates the turning module 20 with the conveying module 10. The material is fed into the turning fixture 23 by the conveyor belt 11, and the turning fixture 23 completes the turning action on the conveyor belt 11 in the same direction as the conveyor belt. This allows the material to return to the conveyor belt 11 to complete the discharge while it is being turned. The process is simple, the operation is smooth, and the work efficiency is high.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
