Description

Technical Field

[0001] The invention relates to a conveyor with the functions of adjusting the width of a conveying surface and flipping, belonging to the technical field of logistics transportation. Background Art

[0002] Some workpieces need to be turned over during the production process to facilitate subsequent processing. This turning process is completed by a turning conveyor, which is mainly used to turn the product 180° on the conveyor line. The existing turning conveyor structure consists of two parts: the pressing part and the turning part. The action can be realized by electric, pneumatic and hydraulic systems. my country's utility model patent application number is CN201820071538.5, which discloses a battery loading and flipping conveying device, which includes a first conveying mechanism and a second conveying mechanism extending along the Z-axis direction, and a loading and flipping mechanism is set above the first conveying mechanism and the second conveying mechanism. The loading and flipping mechanism loads the battery sent by the first conveying mechanism and flips it 180° and then places it on the second conveying mechanism for transportation; the loading and flipping mechanism includes a movable guide rail, a mounting frame and a flipping frame. The movable guide rail is set above the first conveying mechanism and the second conveying mechanism and extends along the X-axis direction. The mounting frame is slidably connected to the movable guide rail through a sliding member. The mounting frame is driven by a telescopic driving mechanism to reciprocate along the X-axis direction, and is driven by a lifting driving mechanism to reciprocate along the Y-axis direction. The flipping frame is rotatably arranged in the mounting frame for clamping the battery, and the flipping frame is driven by a flipping driving mechanism to drive the battery to flip 180°.

To ensure the stability of movement, the first optical axis 7 and the second optical axis 8 sequentially penetrate the first fixed plate 1, the moving plate 2 and the second fixed plate 3. By moving the moving plate 2 close to or away from the second fixed plate 3, the purpose of adjusting the width of the conveying surface is achieved to adapt to the transportation of workpieces 62 of different specifications.

[0026] As a specific implementation of this embodiment, the conveying mechanism includes a power component and a transport component; the power component drives the transport component to move, and the transport component is used to transport the workpiece 62. Among them, the power component includes a third motor 41, a third motor seat 42 and a third motor pulley 43; the third motor 41 is respectively installed on the second fixed plate 3 and the movable plate 2 through the third motor seat 42, and the shaft end of the third motor 41 is connected to the third motor pulley 43; the transport component includes a first transport component and a second transport component that are arranged oppositely, the first transport component includes a first reversing wheel 51, a first transmission wheel 52, a first support wheel 53 and a first round belt 54, the first round belt 54 is wound around the first reversing wheel 51, the first transmission wheel 52, the third motor pulley 43 and the first support wheel 53, the second transport component includes a second reversing wheel 51, a first transmission wheel 52, a first support wheel 53 and a first round belt 54, The first reversing wheel 51 is connected with the driving gear 59, the driving gear 59 and the driven gear 60 are mounted on the gear seat 61 and mesh with each other, and the gear seat 61 is respectively mounted on the second fixed plate 3 and the movable plate 2.

[0027] As a specific implementation of this embodiment, the clamping mechanism includes a photoelectric position sensor 44, a clamping cylinder 45, a clamping plate 46, a limit cylinder 47, a limit bending plate 48, an entry end photoelectric detection sensor 49, and an outflow end photoelectric detection sensor 50, wherein the entry end photoelectric detection sensor 49 and the outflow end photoelectric detection sensor 50 are respectively installed at both ends of the conveying mechanism, the photoelectric position sensor 44 is installed on the second fixed plate 3, the clamping cylinder 45 and the limit cylinder 47 are respectively symmetrically installed on the second fixed plate 3 and the movable plate 2, one end of the limit bending plate 48 is installed on the output end of the limit cylinder 47, and one end of the clamping plate 46 is installed on the output end of the clamping cylinder 45, and the other ends of the limit bending plate 48 and the clamping plate 46 both extend between the movable plate 2 and the second fixed plate 3.

When the workpiece 62 enters the conveying mechanism, the entry end photoelectric detection sensor 49 detects the entry signal.

Then the driving mechanism drives the width adjusting mechanism to flip, and after the workpiece 62 completes the relevant processing, the driving mechanism drives the width adjusting mechanism to flip in the opposite direction, and after the relevant processing is completed, the driving mechanism drives the width adjusting mechanism to reset, and the limiting cylinder 47 and the clamping cylinder extend respectively, thereby separating the limiting bending plate 48 and the clamping plate 46 from the workpiece 62, and the conveying mechanism conveys the processed workpiece 62 away. When the outflow end photoelectric detection sensor 50 detects the outflow signal, it indicates that the workpiece 62 has left the conveying mechanism.

[0028] Example 2: Figures 1 to 7As shown, on the basis of Example 1, a guide rail 19 is provided at the bottom of the first fixed plate 1 and the second fixed plate 3, a width adjustment sensor 20 is installed on the guide rail 19, a width adjustment detection plate 21 is installed at the bottom of the movable plate 2, and the width adjustment sensor 20 is used to detect the position of the width adjustment detection plate 21. The driving mechanism includes a first motor 26, a first reducer 27, a first motor seat 28, a first coupling 29, a first bearing seat 30, a first rotating shaft 31 and a first rotating shaft seat 32, wherein the first reducer 27 is installed on the first motor seat 28, the first motor 26 is connected to the first reducer 27, the first rotating shaft 31 passes through the first bearing seat 30 and is fixedly connected to the first rotating shaft seat 32, the first coupling 29 fixes the first reducer 27 and the first rotating shaft 31, and the first rotating shaft seat 32 is installed on the first fixed plate 1.

[0029] The first motor 26 drives the width adjustment mechanism to flip. When the first motor 26 rotates forward, the width adjustment mechanism rotates clockwise. When the first motor 26 rotates reversely, the width adjustment mechanism rotates counterclockwise. In this embodiment, by providing a width adjustment in place detection plate 21 and a width adjustment in place sensor 20, when the width adjustment in place sensor 20 detects the position of the width adjustment in place detection plate 21, it indicates that the moving plate 2 has moved into place, thereby achieving precise control and precise displacement.

[0030] Example 3: Figures 1 to 8As shown, on the basis of Example 1, a flipping detection mechanism for monitoring the flipping angle of the width adjusting mechanism is installed on the width adjusting mechanism, and specifically, a flipping detection mechanism is provided on the second fixed plate 3.

When the driving mechanism drives the width adjusting mechanism to flip clockwise, the flip-in-place detection mechanism also flips accordingly. Specifically, the first detection plate 36 flips accordingly. When the first detection plate 36 moves to the first in-place detection sensor 37, the first in-place detection sensor 37 feeds back a forward rotation in-place signal, indicating that the driving mechanism drives the width adjusting mechanism to flip accurately. If the first detection plate 36 continues to rotate clockwise and passes the first in-place detection sensor 37 and is detected in position by the first over-travel detection sensor 39, it indicates that the driving mechanism has not flipped accurately. The first over-travel detection sensor 39 feeds back a forward rotation over-travel signal, and the driving mechanism stops driving immediately. Similarly, the driving mechanism When the mechanism drives the width adjusting mechanism to flip counterclockwise, the flip-in-place detection mechanism also flips accordingly. Specifically, the first detection plate 36 flips accordingly. When the first detection plate 36 moves to the second in-place detection sensor 38, the second in-place detection sensor 38 feeds back a reverse in-place signal, indicating that the driving mechanism drives the width adjusting mechanism to flip accurately. If the first detection plate 36 continues to rotate counterclockwise and passes the second in-place detection sensor 38 and is detected by the second over-travel detection sensor 40, it indicates that the driving mechanism has not flipped accurately. The second over-travel detection sensor 40 feeds back a reverse over-travel signal. At this time, the driving mechanism immediately stops driving to ensure safe operation.

Specifically, the tensioning bolt 24 is rotated to move the tensioning bolt 24 upward, the tensioning bolt 24 lifts the tensioning bracket 25, the tensioning wheel 22 contacts the transmission belt 18, and the transmission belt 18 is gradually lifted to achieve the tensioning of the transmission belt 18; similarly, the tensioning bolt 24 is rotated in the opposite direction, the tensioning bolt 24 moves downward, so that the tensioning wheel 22 is separated from the transmission belt 18, and the tensioned state is released.

[0032] Example 5: Figures 1 to 9 As shown, this embodiment is a combination of embodiments 1-4, and each electrical component is controlled and operated by a PLC controller, and the details are not repeated here.

[0033] Taking Example 5 as an example, Figures 1 to 9As shown, in this embodiment, both the front and back sides of the workpiece 62 need to be processed. This embodiment takes the drilling operation on the workpiece 62 as an example. The working process of the present invention is specifically as follows: according to the specifications of the workpiece 62, the second motor 11 indirectly drives the moving plate 2 to move linearly along the lead screw 4, thereby completing the adjustment of the width of the conveying surface. During the process, the position feedback is performed through the width adjustment detection plate 21 and the width adjustment sensor 20 to achieve precise control. The third motor 41 drives the third motor pulley 43 to rotate, and the third motor pulley 43 drives the first round belt 54 to move, thereby making the first round belt 54 and the second round belt 58 move in the same direction to realize the conveying of the workpiece 62. Specifically, in the initial state, the clamping cylinder extends and the limit cylinder 47 extends. When the workpiece 62 enters the conveying mechanism, the workpiece 62 is in the gap between the first round belt 54 and the second round belt 58, and the photoelectric detection sensor 49 at the entry end of the workpiece 62 detects an entry signal. When the photoelectric position sensor 44 detects the position of the workpiece 62, the limit cylinder 47 retracts and drives the limit bending plate 48 to descend to above the first round belt 54. The limit bending plate 48 prevents the workpiece 62 from moving forward. Then the clamping cylinder retracts and drives the clamping plate 46 to descend. When the end of the clamping plate 46 contacts the upper surface of the workpiece 62, the workpiece 62 is supported by the first support wheel 53, the second support wheel 57 and the second round belt 58 at this time, thereby completing the clamping and fixing of the workpiece 62 to ensure the stability of the workpiece 62 during the flipping process. Then the driving mechanism drives the width adjustment mechanism to flip, and after the workpiece 62 completes the front drilling process, the driving mechanism drives the width adjustment mechanism to flip in the opposite direction, and after the workpiece 62 completes the back drilling process, the driving mechanism drives the width adjustment mechanism to reset, and the limit cylinder 47 and the clamping cylinder extend respectively, so that the limit bending plate 48 and the clamping plate 46 are separated from the workpiece 62, and the limit bending plate 48 and the clamping plate 46 release the workpiece 62, and the conveying mechanism conveys the workpiece 62 after processing. When the outflow end photoelectric detection sensor 50 detects the outflow signal, it indicates that the workpiece 62 has been separated from the conveying mechanism, that is, when the outflow end photoelectric detection sensor 50 cannot detect the workpiece 62, it indicates that the workpiece 62 has been separated from the equipment. When the first motor 26 drives the width adjustment mechanism to flip, the first motor 26 drives the width adjustment mechanism to rotate clockwise when it rotates forward, and drives the width adjustment mechanism to rotate counterclockwise when it rotates reversely. The first in-place detection sensor 37, the second in-place detection sensor 38, the first over-travel detection sensor 39, and the second over-travel detection sensor 40 are respectively used to detect the position of the first detection plate 36, that is, the width adjustment mechanism or the flip angle of the workpiece 62. The first in-place detection sensor 37, the second in-place detection sensor 38, the first over-travel detection sensor 39, and the second over-travel detection sensor 40 respectively feed back a forward rotation in-place signal, a reverse rotation in-place signal, a forward rotation over-travel signal, and a reverse rotation over-travel signal.
