When the workpiece is transported to the processing section, it generally needs to be parked in a specific location for storage or subsequent processing.

[0003] In the prior art, due to the different characteristics of the workpieces themselves, the conveying methods used are also different. In the processing of mechanical parts such as horizontal and longitudinal beams, due to the large mass and size of the mechanical parts, the workpieces are usually conveyed by rollers driven by servo motors, and the parking of the workpieces is achieved by stopping the servo motor.

[0004] However, in the prior art, the parking position of the workpiece is controlled solely by a servo motor, whose parameters are often preset in advance, and can only park workpieces of the same size at the same position, but cannot accurately park workpieces at different positions. For example, when a longitudinal beam needs to be centered at a certain reference position, the servo motor can only park a longitudinal beam of a certain size in place, and if the longitudinal beam of the specific size needs to be centered at a different reference position, or longitudinal beams of different sizes need to be centered at the same reference position, only manual intervention can be performed, and the parking position will deteriorate greatly. Therefore, how to make the conveyor roller accurately park the workpiece at multiple positions when conveying the workpiece has become a technical problem to be solved. Utility Model Content

[0038] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0039] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0041] In the processing of mechanical parts such as horizontal and longitudinal beams, due to the large mass and size of the mechanical parts, workpieces are usually transported by rollers driven by servo motors, and the parking of the workpieces is achieved by stopping the servo motors. However, the parking position of the workpiece is only controlled by the servo motor, which can only park workpieces of the same size in the same position, but cannot accurately park the workpieces in different positions. For example, when the longitudinal beam needs to be parked in the center at a certain reference position, the servo motor can only park a longitudinal beam of a certain size in place, and if the longitudinal beam of a certain size needs to be parked in the center at a different reference position, or longitudinal beams of different sizes need to be parked in the center at the same reference position, manual intervention can only be performed, and the parking position will deteriorate greatly. Therefore, how to make the conveyor roller accurately park the workpiece at multiple positions when conveying the workpiece has become a technical problem to be solved.

[0042] In this regard, the present embodiment provides a multi-position stop roller, the guide rails of which are arranged side by side with the conveying roller, so that the moving path of the movable frame on the guide rails is parallel to the conveying path of the conveying roller, and the sensor fixed on the movable frame can move with the movable frame. When the parking position of the workpiece needs to be changed, the position of the sensor only needs to be moved to the target position through the movable frame, and the first power member can stop conveying according to the sensor signal when the workpiece reaches the target position, so that the workpiece can be accurately parked at the target position, thereby enabling the workpiece to be accurately parked at different positions, meeting the multi-position stop requirements during the workpiece conveying process.

[0043] The code reading device is introduced below in conjunction with the accompanying drawings. Those skilled in the art should understand that the following implementations are only illustrative and not exhaustive. Based on these implementations, those skilled in the art may replace, splice or combine certain features or examples, which should still be regarded as the disclosed content of this application.

[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 1 This is a schematic diagram of the overall structure of a multi-position stop roller conveyor provided in an embodiment of the present application. Figure 2 is a first partial schematic diagram of a positioning assembly of a multi-position stop roller conveyor provided in an embodiment of the present application, Figure 3 is a second partial schematic diagram of a positioning assembly of a multi-position stop roller conveyor provided in an embodiment of the present application, Figure 4 The figure is a partial schematic diagram of a conveying assembly of a multi-stop roller conveyor provided in an embodiment of the present application, wherein the multi-stop roller conveyor comprises: a conveying assembly and a positioning assembly.

[0045] The conveying assembly is a structure for conveying workpieces, which includes: a first power member 10 and a conveying roller 20. A plurality of conveying rollers 21 are arranged on the conveying path of the conveying roller 20, thereby forming a conveying channel for the workpiece. The first power member 10 is connected to the conveying roller 21 and provides conveying power to the conveying roller 21. At the same time, the first power member 10 can receive the signal of the sensor 50 and adjust the power output process according to the signal of the sensor 50, such as stopping the power output according to the sensor 50, reducing the power output, etc. The first power member 10 is preferably a servo motor, and can also be set to other controllable power structures, which are not limited here.

[0046] Further, such as Figure 1 and Figure 4 As shown, the conveying roller 21 may include an active roller 211 and a driven roller 212; the first power member 10 is connected to the active roller 211 and provides conveying power for the active roller 211, and the driven roller 212 is rotatably arranged on the conveying path of the conveying roller 20 and can rotate under the friction of the workpiece.

[0047] The active roller 211 moves along with the power transmission process of the first power member 10. That is, when the first power member 10 outputs power, the active roller 211 rotates accordingly. When the first power member 10 increases or decreases the power output, the active roller 211 accelerates or decelerates accordingly. When the first power member 10 stops outputting power, the active roller 211 stops rotating accordingly.

[0048] The driven roller 212 is rotatably installed side by side with the active roller 211 so as to be in a free state. When the workpiece is conveyed, the workpiece is first conveyed to press the active roller 211, and the active roller 211 rotates under the power of the first power member 10. The friction between the active roller 211 and the workpiece drives the workpiece to move on the conveying path. Since the workpiece and the driven roller 212 are in point-line contact, the friction is small, so that the workpiece can be smoothly slid and conveyed on the conveying roller 20.

[0049] There are many ways to connect the first power member 10 and the active roller 211. One feasible implementation method is as follows: Figure 5 As shown, Figure 5 This is a partial structural diagram of a first power member of a multi-position stop roller provided in an embodiment of the present application. The first power member 10 is connected to the driving sprocket 11 and drives the driving sprocket 11 to rotate. The driving sprocket 11 is connected to the driven sprocket 13 through the chain 12 to drive the driven sprocket 13 to rotate. The driven sprocket 13 is coaxially connected to the driving roller 211 and drives the driving roller 211 to rotate. In addition, the first power member 10 and the driving roller 211 can also be completely connected through a gear set, or other feasible connection methods, which are not limited here.

[0050] The positioning assembly is a structure of the auxiliary conveying assembly, which is used to locate the parking position of the workpiece, so that the first power member 10 stops conveying in time and parks the workpiece at the position where it should be parked. Figure 2 and Figure 3 As shown, the positioning assembly includes: a guide rail 30, a movable frame 40, and a sensor 50. The guide rail 30 and the conveying roller 20 are arranged side by side, and a moving member 41 cooperating with the guide rail 30 is arranged on the movable frame 40. The moving path of the movable frame 40 on the guide rail 30 is parallel to the conveying path of the conveying roller 20. The sensor 50 is fixed on the movable frame 40 and is located on the conveying path of the conveying roller 20. The sensor 50 can move on the guide rail 30 with the movable frame 40; the sensor 50 is connected to the first power member 10, so that the first power member 10 stops conveying according to the signal generated by the sensor 50, so as to park the workpiece at the corresponding position of the sensor 50.

[0051] In the positioning assembly, the guide rail 30 is fixedly mounted on the frame, the movable frame 40 is movably mounted on the guide rail 30 through the moving member 41, and the sensor 50 is mounted on the movable frame 40 and is located on the conveying path of the conveying roller 20. When the parking position of the workpiece needs to be changed, the movable frame 40 is moved on the guide rail 30, which drives the sensor 50 to move on the conveying path of the conveying roller 20, thereby changing the position of the sensor 50 on the conveying path of the conveying roller 20. When the workpiece is transported to the position of the sensor 50, the first power member 10 receives the signal generated by the sensor 50 and changes the power output process, so that the workpiece is parked at the position where it should be parked, that is, the corresponding position of the sensor 50.

[0052] Take the example of conveying two workpieces of different sizes to a specific reference position O for centering and parking. If one workpiece A is 3 meters long and the other workpiece B is 2 meters long, and the two workpieces are to be successively centering and parking at point O, the sensor 50 is first moved to a position 1.5 meters away from point O, and the conveying direction of the workpiece is from point O to the sensor 50. When the end of workpiece A is detected by the sensor 50, the sensor 50 generates a signal and stops the conveying of the first power member 10, so that workpiece A is centering and parking at point O. When workpiece A is processed and conveyed away, the movable frame 40 is moved to make the sensor 50 close to point O, so that the sensor 50 is moved to a position 1 meter away from point O, and then workpiece B is conveyed.

[0053] There are many structural forms of the guide rail 30 and the moving member 41, and the structural forms and quantities of the two are corresponding. For example, if the guide rail 30 is set as a slide groove, the moving member 41 can be correspondingly set as a slider or roller embedded in the slide groove. If there are two guide rails 30, the moving member 41 can be correspondingly set as two or more.

[0054] There are many ways to install the sensor 50 on the movable frame 40 and on the conveying path of the conveyor roller 20. In one feasible implementation, a crossbeam 42 extending from the guide rail 30 to the conveyor roller 20 can be provided on the movable frame 40, and then the sensor 50 is installed on the crossbeam 42, and the crossbeam 42 is separated from the conveyor roller 20 by a preset distance. When the movable frame 40 moves on the guide rail 30, the crossbeam 42 moves in the conveying direction of the conveyor roller 20, thereby driving the sensor 50 to move synchronously.

[0055] The sensor 50 may also be provided in a plurality, and multiple types of sensors 50 may be provided. A feasible implementation may be as follows Figure 2 As shown, the sensor 50 includes a deceleration sensor 51 and a stop sensor 52, and both the deceleration sensor 51 and the stop sensor 52 are connected to the first power member 10; the stop sensor 52 is located at a parking position at the end of the workpiece, and the deceleration sensor 51 and the stop sensor 52 are separated by a preset distance, and the deceleration sensor 51 is located before the stop sensor 52 on the conveying path of the conveyor roller 20, so that the first power member 10 reduces the conveying rate according to the signal generated by the deceleration sensor 51, and then stops conveying according to the signal generated by the stop sensor 52.

[0056] In this embodiment, a deceleration sensor 51 and a stop sensor 52 are provided at the same time, and the deceleration sensor 51 senses the workpiece and generates a signal before the stop sensor 52, so that when the workpiece is about to be transported to the parking position, the signal generated by the deceleration sensor 51 causes the first power member 10 to reduce the power transmission, that is, to reduce the conveying rate of the workpiece. Furthermore, when the workpiece reaches the parking position, the signal generated by the stop sensor 52 causes the first power member 10 to stop the power transmission. At this time, since the conveying rate of the workpiece is relatively low, the workpiece can be prevented from continuing to slide due to inertia, thereby further improving the accuracy of the workpiece parking.

[0057] There are many options for the sensor 50 of the deceleration sensor 51 and the stop sensor 52, such as a pressure sensor, an optical sensor, a magnetic sensor, etc., which are not limited here. Figure 2 As shown, the stop sensor 52 is a pressure sensor, which is connected to the top plate 53 and generates a signal when the workpiece abuts against the top plate 53. When the workpiece is transported, it will first pass through the deceleration sensor 51. The signal generated by the deceleration sensor 51 causes the first power member 10 to reduce the power output, and the workpiece decelerates and continues to approach the stop sensor 52. When the workpiece abuts against the top plate 53, the stop sensor 52 senses the pressure and generates a signal to stop the power output of the first power member 10, and the workpiece stops at the position abutting against the top plate 53.

[0058] The sensor 50 is connected to the first power component 10, which means that the sensor 50 is communicatively connected to the first power component 10, which can be a wired connection or a wireless connection, so as to transmit the signal of the sensor 50 to the first power component 10, so that the first power component 10 changes the power output process according to the signal generated by the sensor 50.

[0059] In this embodiment, the movable frame 40 can move on the guide rail 30 under the action of external force. The external force can come from manual force or from a second power member 60 different from the first power member 10, which is not limited here.

[0060] When the second power member 60 is used to apply force to the movable frame 40, a feasible implementation method is as follows: Figure 2 , Figure 3 and Figure 6 As shown, Figure 6 1 is a cross-sectional view of a positioning assembly of a multi-position stop roller conveyor provided in an embodiment of the present application. The positioning assembly further includes a second power member 60 and a transmission member 70; the second power member 60 is located at the first end of the guide rail 30; the second power member 60 is connected to the movable frame 40 through the transmission member 70 to drive the movable frame 40 to move back and forth between the first end of the guide rail 30 and the second end of the guide rail 30.

[0061] In this embodiment, the second power member 60 is arranged at the first end of the guide rail 30, and the transmission member 70 applies force to the movable frame 40, pulling the movable frame 40 toward the second power member 60 or pushing the second power member 60 toward the second end, thereby ensuring the spatial layout of the overall mechanism and making the force transmission direction single, thereby avoiding power loss.

[0062] There are many ways to set the transmission member 70. One feasible implementation is as follows: Figure 6 As shown, the transmission member 70 includes a driving wheel 71, a belt 72 and a driven wheel 73; the driving wheel 71 is connected to the second power member 60 and rotates under the power of the second power member 60, the driven wheel 73 is rotatably arranged on the base frame and is located at the second end of the guide rail 30, the driving wheel 71 and the driven wheel 73 are connected by a belt 72, so that the driving wheel 71, the belt 72 and the driven wheel 73 rotate synchronously; the belt 72 is fixedly connected to the movable frame 40, and when the belt 72 rotates, it pulls the movable frame 40 to move on the guide rail 30.

[0063] In this embodiment, the belt 72 is sleeved between the driving wheel 71 and the driven wheel 73, the driving wheel 71 is connected to the second power member 60, and the driven wheel 73 is in a rotatable free state. When the second power member 60 is working, the second power member 60 drives the driving wheel 71 to rotate, and the belt 72 will rotate accordingly. The belt 72 is also fixedly connected to the movable frame 40. During the rotation of the belt 72, the movable frame 40 will be driven to move on the guide rail 30, so that the code reader installed on the movable frame 40 will move accordingly.

[0064] There are many ways to fix the belt 72 and the movable frame 40. One feasible implementation is as follows: Figure 3 and Figure 6 As shown, a clamping structure 43 is provided on the movable frame 40, and the clamping structure 43 clamps the belt 72 so that the belt 72 is fixedly connected to the movable frame 40. Of course, the belt 72 and the movable belt can also be fixedly connected by bonding, clamping, etc., which is not limited here.

[0065] In addition, other settings can be made to the positioning component, such as setting the driving wheel 71 and / or the driven wheel 73 in the transmission member 70 as gears, setting blocks at both ends of the guide rail 30 to prevent the movable frame 40 from leaving the guide rail 30, setting a positioning scale to locate the position of the movable frame 40, etc., which are not limited here.

[0066] In addition, in this embodiment, multiple conveyor rollers 20 can also be set up to convey multiple workpieces of the same size to a flush position, so as to facilitate simultaneous processing of multiple workpieces. A feasible implementation is that the conveyor roller 20 includes a first conveyor roller and a second conveyor roller, the first conveyor roller and the second conveyor roller are arranged side by side, and the first conveyor roller and the second conveyor roller share an active roller connected to the first power member, so that the first conveyor roller and the second conveyor roller synchronously convey two workpieces under the drive of the active roller. Of course, correspondingly, multiple sensors 50 can be set corresponding to the conveyor rollers, that is, the sensor 50 includes a first sensor and a second sensor, the first sensor is fixed on the movable frame 40 and is located on the first conveying path of the first conveyor roller, and the second sensor is fixed on the movable frame 40 and is located on the second conveying path of the second conveyor roller. In addition, in other feasible implementations, different conveyor rollers 20 can also use different active rollers driven by different power members, which is not limited here.

[0067] In addition, since some workpieces are slender structures, they may be skewed during the transportation process, causing the workpiece to be parked in the wrong position. In this regard, this embodiment provides an implementation method for solving this problem. Figure 4As shown, a positioning clamp 22 is provided on the conveying path of the conveyor roller 20; the positioning clamp 22 includes a first clamp 221 and a second clamp 222, and the first clamp 221 and the second clamp 222 can move toward each other, so that after the workpiece passes between the first clamp 221 and the second clamp 222, the distance between the first clamp 221 and the second clamp 222 is reduced to limit the workpiece to be conveyed along the conveying path of the conveyor roller 20.

[0068] In this embodiment, the first clamping claw 221 and the second clamping claw 222 are equivalent to structures that can move toward each other and clamp the conveying roller 20 in the middle. When the workpiece passes through the first clamping claw 221 and the second clamping claw 222, the distance between the first clamping claw 221 and the second clamping claw 222 is reduced, thereby limiting the space for the workpiece to swing horizontally, so that the workpiece can only be transported along the conveying path of the conveying roller 20, thereby avoiding the occurrence of workpiece deflection, and further ensuring that the workpiece is parked at the correct position.

[0069] In the multi-position stop roller conveyor provided by the present application, the guide rail 30 and the conveying roller conveyor 20 are arranged side by side, so that the moving path of the movable frame 40 on the guide rail 30 is parallel to the conveying path of the conveying roller conveyor 20, and the sensor 50 fixed on the movable frame 40 can move with the movable frame 40. When it is necessary to change the parking position of the workpiece, it is only necessary to move the position of the sensor 50 to the target position through the movable frame 40, and the first power member 10 can stop conveying according to the signal of the sensor 50 when the workpiece reaches the target position, so that the workpiece can be accurately parked at the target position, so that the workpiece can be accurately parked at different positions, meeting the multi-position stop requirements during the workpiece conveying process.

[0070] It should be noted that, although several structures, components or units for realizing related functions are mentioned in the above detailed description, such division is not mandatory. In fact, according to the specific implementation of the present application, the features and functions of two or more structures, components or units described above can be concretized in one structure, component or unit. Conversely, the features and functions of one structure, component or unit described above can be further divided into multiple components, structures or units to be concretized.
