Description

Technical Field

[0001] The present application belongs to the technical field of conveying equipment, and specifically relates to a workpiece conveyor. Background Art

[0002] With the continuous development of my country's manufacturing industry, the requirements for industrial automation are getting higher and higher. When the workpiece is being manufactured and processed, it is accompanied by the transportation between multiple processes. The workpiece transportation equipment is used to transfer the workpiece between each process. In traditional workpiece transportation equipment, multiple workpieces are arranged in sequence on the transmission line and continue to move forward with the movement of the transmission line. When the workpiece moves along the transmission line to the preset position, it can be transferred to the next process by clamping and other methods. When there are many workpieces on the transmission line, multiple workpieces may be close to each other, which makes it difficult to clamp the workpiece and affects the clamping efficiency. In the process of clamping the workpiece, it may touch the adjacent workpiece, causing the workpiece to fall, etc., which requires the operator to pay attention at all times, further affecting the transportation efficiency of the workpiece. Utility Model Content

[0003] The present application provides a workpiece conveyor to solve the technical problems of low transportation efficiency of traditional workpiece transportation equipment and easy mutual influence between adjacent workpieces during transfer to the next process.

[0004] The technical solution adopted in this application is:

[0005] A workpiece conveyor is used to convey workpieces to be processed to a processing unit, comprising a frame, a conveyor belt is provided on the top of the frame, a transmission channel for the workpiece to pass through the top of the conveyor belt, the transmission channel comprises a conveying section and a grabbing section for the processing unit to grab the workpiece, and also comprises a first limiting mechanism, the first limiting mechanism has a first stop state in which at least a part of the area is located in the conveying section and a first relaxation state in which the whole area is located outside the conveying section, when the first limiting mechanism is in the first stop state, it can stop the workpiece located in the conveying section to limit the movement of the workpiece along the transmission channel, and the first limiting mechanism can switch between the first stop state and the first relaxation state.

[0006] The workpiece conveyor described in this application also includes the following additional technical features:

[0007] The first limiting mechanism includes a driving part and a limiting rod, the limiting rod having a stop position and a release position. When the limiting rod is located at the stop position, at least a portion of the limiting rod is located on the conveying section to stop the workpiece. When the limiting rod is in the release position, the limiting rod is entirely outside the conveying section. The driving part can drive the limiting rod to switch between the stop position and the release position, thereby driving the first limiting mechanism to switch between the first stop state and the first release state.

[0008] The first limiting mechanism also includes a mounting seat, which has a mounting end and a bearing end, the mounting end is in contact with the frame, one end of the bearing end is connected to the mounting end, and the other end extends horizontally away from the mounting end and forms a bearing surface on the top of the bearing end for bearing the driving part.

[0009] The grabbing section is provided with a first grabbing position and a second grabbing position in sequence along the extension path of the conveyor belt, so that the processing unit can grab the workpieces located at the first grabbing position and the second grabbing position at the same time.

[0010] It also includes a second limiting mechanism located at the first gripping position, the second limiting mechanism having a second stop state in which at least a portion of the area is located in the gripping section and a second relaxed state in which the entire area is located outside the gripping section, and the second limiting mechanism can switch between the second stop state and the second relaxed state.

[0011] The invention also comprises a workpiece stopping structure located at the second gripping position away from the first gripping position, wherein the workpiece stopping structure comprises a stopping portion opening toward the second gripping position, and the stopping portion can abut against the workpiece to limit the movement of the workpiece.

[0012] The workpiece stopping structure further comprises a fixing seat, which is fixed to the frame and has a fixing surface formed on its top surface for supporting the stopping portion, and the stopping portion is detachably connected to the fixing seat.

[0013] The transmission belt includes a first straight line segment and a second straight line segment, and the first straight line segment and the second straight line segment are connected via a bending segment.

[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0015] 1. The workpiece conveyor of the present application adopts a conveyor belt to transport workpieces. The workpiece advances along the conveying channel as the conveyor belt is conveyed, thereby ensuring the smoothness of the workpiece conveying. The conveying channel includes a conveying section and a grabbing section. The workpiece located in the grabbing section is grabbed and sent to a subsequent processing unit for subsequent processing. Since a first limiting mechanism is provided, when the workpiece to be grabbed enters the grabbing section, the first limiting mechanism can switch to a first stop state to stop the workpiece located in the conveying section, thereby limiting the continued advancement of the workpiece and avoiding interference with the workpiece to be grabbed located in the grabbing section, thereby facilitating the grabbing mechanism to accurately grab the workpiece to be grabbed. After the workpiece to be grabbed located in the grabbing section is grabbed, the first limiting mechanism switches to a first release state to allow the workpiece on the conveying section to continue to advance toward the grabbing section; this reciprocating process allows only the workpiece to be grabbed to exist on the grabbing section, effectively preventing other workpieces from interfering with the workpiece to be grabbed, thereby helping to improve the conveying accuracy of the workpiece conveyor.

[0016] 2. As a preferred embodiment of the present application, a driving unit and a limit rod are provided, and the limit rod is driven by the driving unit to switch between the stop position and the release position, thereby driving the first limit mechanism to switch between the first stop state and the first release state. The limit rod can quickly switch between the stop position and the release position under the drive of the driving unit, thereby reducing the probability of the limit rod failing to stop the workpiece on the conveying section in time due to the slow movement speed of the limit rod. In addition, when the limit rod is in the stop position, the front end of the workpiece in the movement direction is against the limit rod and cannot continue to move. The limit rod is located at the front end of the workpiece, and the stopping force applied by the limit rod to the workpiece coincides with the extension direction of the transmission channel, which helps to maintain the load stability of the workpiece on the conveyor belt.

[0017] 3. As a preferred embodiment of the present application, the grabbing section is provided with a first grabbing position and a second grabbing position in sequence along the extension path of the conveyor belt, so that the processing unit can grab the workpieces located at the first grabbing position and the second grabbing position at the same time. By providing the first grabbing position and the second grabbing position in the grabbing section, the grabbing section can accommodate two workpieces at a time, and two workpieces can be grabbed each time, thereby improving the workpiece conveying efficiency of the workpiece conveyor to the processing unit. When the workpiece conveying volume is large, the probability of workpiece accumulation on the conveying section caused by too slow a grabbing speed can be effectively reduced.

[0036] like Figures 1 to 5 As shown, a workpiece conveyor is used to convey workpieces to be processed to a processing unit, including a frame 1, a conveyor belt 2 is provided on the top of the frame 1, and a transmission channel for the workpiece 6 to pass through the top of the conveyor belt 2, and the transmission channel includes a conveying section and a grabbing section for the processing unit to grab the workpiece 6, and also includes a first limiting mechanism 3, the first limiting mechanism 3 has a first stop state in which at least a part of the area is located in the conveying section and a first relaxation state in which the whole area is located outside the conveying section. When the first limiting mechanism 3 is in the first stop state, it can stop the workpiece 6 located in the conveying section to limit the movement of the workpiece 6 along the transmission channel, and the first limiting mechanism 3 can switch between the first stop state and the first relaxation state.

[0037] The workpiece conveyor of the present application adopts a conveyor belt 2 to transport the workpiece. The workpiece advances along the conveying channel as the conveyor belt 2 is conveyed, thereby ensuring the smoothness of the workpiece conveying. The conveying channel includes a conveying section and a grabbing section. The workpiece 6 located in the grabbing section is grabbed and sent to a subsequent processing unit for subsequent processing. Since a first limiting mechanism 3 is provided, when the workpiece 6 to be grabbed enters the grabbing section, the first limiting mechanism 3 can switch to a first stop state to stop the workpiece located in the conveying section, thereby limiting the continued advancement of the workpiece, avoiding interference with the workpiece to be grabbed located in the grabbing section, and facilitating the grabbing mechanism to accurately grab the workpiece to be grabbed. After the workpiece 6 to be grabbed located in the grabbing section is grabbed, the first limiting mechanism 3 switches to a first relaxation state to allow the workpiece 6 on the conveying section to continue to advance toward the grabbing section; this reciprocating process allows only the workpiece 6 to be grabbed to be on the grabbing section, effectively preventing other workpieces from interfering with the workpiece 6 to be grabbed, thereby helping to improve the conveying accuracy of the workpiece conveyor.

[0038] The workpiece conveyor of the present application does not limit the structure of the workpiece to be conveyed. Figure 1 The figure shows the conveying of hollow pipes. Taking the conveying of pipes as an example, the working process of the workpiece conveyor is as follows: the pipes are continuously moved under the drive of the conveyor belt 2. When the pipes enter the grabbing section from the conveying section, the first limiting mechanism 3 switches from the first relaxation state to the first stop state. The pipes on the conveying section closest to the grabbing section cannot continue to move forward under the limiting action of the first limiting mechanism 3, and prevent the subsequent other pipes from continuing to move forward. When the pipes in the grabbing section are grabbed, the first limiting mechanism 3 switches from the first stop state back to the first relaxation state, and the pipes on the conveying section can continue to move toward the grabbing section. The transmission channel, conveying section and grabbing section in this application all refer to the space occupied by the workpieces at the top of the conveyor belt 2 when they move.

[0039] Preferably, the first limiting mechanism 3 is installed on the frame 1 and located on the side of the conveyor belt 2 .

[0040] As a preferred implementation of the present application, Figure 2 , Figure 4 , Figure 5 As shown, the first limiting mechanism 3 includes a driving part 31 and a limiting rod 32, and the limiting rod 32 has a stop position and a release position. When the limiting rod 32 is located at the stop position, at least a portion of the limiting rod 32 is located on the conveying section to stop the workpiece. When the limiting rod 32 is in the release position, the limiting rod 32 is entirely outside the conveying section. The driving part 31 can drive the limiting rod 32 to switch between the stop position and the release position, thereby driving the first limiting mechanism 3 to switch between the first stop state and the first release state.

[0041] Specifically, Figure 4The middle limiting rod 32 is in the relaxed position, and the first limiting mechanism 3 is in the first relaxed state; Figure 5 The middle limiting rod 32 is in the stopping position, and the first limiting mechanism 3 is in the first stopping state.

[0042] By setting a driving part 31 and a limit rod 32, and driving the limit rod 32 to switch between the stop position and the release position through the driving part 31, the first limit mechanism 3 is driven to switch between the first stop state and the first release state. The limit rod 32 can quickly switch between the stop position and the release position under the driving of the driving part 31, thereby reducing the probability of the limit rod 32 failing to stop the workpiece on the conveying section in time due to the slow movement speed of the limit rod 32. In addition, when the limit rod 32 is in the stop position, the front end of the workpiece in the moving direction is against the limit rod 32 and cannot continue to move. The limit rod 32 is located at the front end of the workpiece, and the stop force applied by the limit rod 32 to the workpiece coincides with the extension direction of the transmission channel, which helps to maintain the load stability of the workpiece on the conveyor belt 2.

[0043] Preferably, if Figure 2 As shown, the limit rod 32 extends in the horizontal direction. When the limit rod 32 is in the relaxed position, it is located on the side of the conveyor belt 2 and will not block the workpiece on the conveyor belt 2. When the limit rod 32 is in the stop position, the limit rod 32 extends above the conveyor belt 2, that is, it is located in the transmission channel. When the workpiece moves along the transmission channel driven by the conveyor belt 2, the limit rod 32 will block the front end of the workpiece and prevent the workpiece from moving forward, thereby achieving the stopping of the workpiece on the conveying section.

[0044] As a preferred embodiment of this implementation, Figure 2 As shown, the first limiting mechanism 3 also includes a mounting seat 33, the mounting seat 33 has a mounting end 331 and a bearing end 332, the mounting end 331 is in contact with the frame 1, one end of the bearing end 332 is connected to the mounting end 331, and the other end extends in a horizontal direction away from the mounting end 331 and forms a bearing surface for bearing the driving part 31 at the top of the bearing end 332. By setting up the mounting seat 33, a mounting platform is provided for the driving part 31, so that the frame 1, on the basis of carrying the conveyor belt 2, is further integrated with the function of providing a mounting position for the first limiting mechanism 3, thereby optimizing the structural design of the workpiece conveyor; in addition, the mounting end 331 is attached to the frame 1, and the bearing end 332 extends in the horizontal direction, so that the driving part 31 and the limiting rod 32 installed on the bearing surface also extend in the horizontal direction, and the limiting rod 32 is in the horizontal direction when switching between the stop position and the release position, that is, the setting of the bearing end 332 provides a certain guiding effect for the movement of the limiting rod 32, and provides stability guarantee for the precise stopping of the workpiece by the limiting rod 32.

[0045] This embodiment does not limit the connection methods between the mounting base 33 and the frame 1 and the driving part 31 respectively. The mounting base 33 and the frame 1 can be connected by bolt connection, welding, clamping, etc.; the mounting base 33 and the driving part 31 can be connected by bolt connection, welding, clamping, etc.

[0046] As a preferred embodiment of the present application, the grabbing section is provided with a first grabbing position and a second grabbing position in sequence along the extension path of the conveyor belt 2, so that the processing unit can grab the workpieces located at the first grabbing position and the second grabbing position at the same time. By providing the first grabbing position and the second grabbing position in the grabbing section, the grabbing section can accommodate two workpieces to enter at a time, and two workpieces can be grabbed each time, thereby improving the workpiece conveying efficiency of the workpiece conveyor to the processing unit. When the workpiece conveying volume is large, the probability of workpiece accumulation on the conveying section caused by too slow a grabbing speed can be effectively reduced.

[0047] As a preferred embodiment of this implementation, Figure 4 As shown, it also includes a second limiting mechanism 4 located at the first grasping position, the second limiting mechanism 4 has a first stop state in which at least part of the area is located in the grasping section and a first relaxed state in which the entire area is located outside the grasping section, and the first limiting mechanism 3 can switch between the first stop state and the first relaxed state. When two workpieces to be grasped enter the grasping section, the second limiting mechanism 4 is in a relaxed state, and the workpieces first continue to move forward under the transmission action of the conveyor belt 2. When the workpiece located at the front side passes the first grasping position, the second limiting mechanism 4 switches from the second relaxed state to the second stop state, and stops the workpiece located at the rear side, limiting the workpiece at the rear side to the first grasping position. When the front workpiece moves to the second grasping position, the grasping unit grasps the workpieces located at the first grasping position and the second grasping position respectively. After the grasping is completed, the second limiting mechanism 4 switches from the second stop state to the second relaxed state, waiting for the next batch of two workpieces to enter the grasping section.

[0048] As another preferred embodiment of this embodiment, Figure 5As shown, it also includes a workpiece stop structure 5 located at the second gripping position away from the first gripping position, and the workpiece stop structure 5 includes a stop portion 51 opening toward the second gripping position, and the stop portion 51 can abut against the workpiece to limit the movement of the workpiece. When two workpieces enter the gripping section, the workpiece located at the rear side stops at the first gripping position, and the workpiece located at the front side continues to move under the drive of the conveyor belt 2. When the front side workpiece moves to the second gripping position, the workpiece stop structure 5 can stop the workpiece and limit the continued movement of the workpiece, thereby ensuring that the front workpiece can be stably placed in the second gripping position, which is convenient for the gripping unit to accurately grip the workpiece; in addition, the workpiece stop structure 5 also includes a stop portion 51 opening toward the second gripping position. When the workpiece moves to the second gripping position, the stop portion 51 can play a certain wrapping role on the workpiece, providing a guarantee for the stability of the workpiece staying at the second gripping position.

[0049] As a preferred example under this embodiment, Figure 3 As shown, the workpiece stop structure 5 also includes a fixed seat 52, which is fixed to the frame 1 and forms a fixed surface on its top surface for carrying the stop portion 51, and the stop portion 51 is detachably connected to the fixed seat 52. By setting the fixed seat 52, a mounting position is provided for the workpiece stop structure 5, and at the same time, the frame 1 further integrates the function of carrying the workpiece stop structure 5 on the basis of bearing the function of the conveyor belt 2, and the function is further integrated, which optimizes the structural design of the workpiece conveyor; in addition, the stop portion 51 is detachably connected to the fixed seat 52, which is convenient for replacing a suitable stop portion 51 according to the structural form and size of the workpiece, thereby improving the adaptability of the workpiece stop structure 5 to the type of workpiece.

[0050] This example does not limit the detachable connection method between the stopper 51 and the fixing seat 52, and they can be connected by bolt connection, clamping connection, etc.

[0051] As a preferred implementation of the present application, Figure 1 As shown, the conveyor belt 2 includes a first straight segment 21 and a second straight segment 22, and the first straight segment 21 and the second straight segment 22 are connected by a bending segment 23. Since the workpiece conveyor needs to be connected to the workpiece production equipment in the preceding process through the conveyor belt 2, such a configuration makes the extension direction of the conveyor belt 2 more diverse, and facilitates the reasonable setting of the layout position of the workpiece conveyor according to the spatial arrangement requirements.
