Description

Technical Field

[0001] This invention relates to the field of transmission equipment, and more specifically to a dual-line single-motor clutch-type transmission system. Background Technology

[0002] In the prior art, a workpiece conveying system is used to convey workpieces. The workpiece conveying system includes: a conveying pull structure, a frame, and a rotary drive mechanism. The conveying pull mechanism is installed at the output end of the rotary drive mechanism, which is mounted on the frame. The conveying pull structure is cyclically movable on the frame and can be a chain or a conveyor belt. A driven shaft is installed at one end of the frame, and the conveying pull structure surrounds the output end of the rotary drive mechanism and the driven shaft. The rotary drive mechanism is a motor connected to pulleys or sprockets, and the workpiece to be conveyed is placed on the top surface of the conveying pull structure.

[0003] Although the above-mentioned workpiece conveying system can continuously transport the workpieces to be transported, it still has the following drawbacks: In actual production processes, it is often necessary to transport two types of workpieces to their respective endpoints. The rotary drive mechanism drives a single conveying and pulling structure, which cannot transport two types of workpieces simultaneously. Different rotary drive mechanisms are required, which increases the equipment cost. Summary of the Invention

[0004] The present invention provides a dual-line single-motor clutch-driven transmission system to solve the problem in the prior art that a single rotary drive mechanism cannot simultaneously transport two types of workpieces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a dual-line single-motor clutch-driven transmission system, comprising: a first transmission pulling structure, a second transmission pulling structure, a first cyclic movement driving mechanism, a second cyclic movement driving mechanism, a frame, and a rotary drive mechanism; both the first and second transmission pulling structures are cyclically movable and mounted on the frame, with a gap between them, and both can cyclically move independently, with the transmission directions of both structures being in the same conveying direction; the rotary drive mechanism is mounted on the frame, and the first and second cyclic movement driving mechanisms are mounted next to the output end of the rotary drive mechanism, with the output end of the first cyclic movement driving mechanism surrounded by the first transmission pulling structure, and the output end of the second cyclic movement driving mechanism surrounded by the second transmission pulling structure. The clutch direction is defined as the direction perpendicular to the conveying direction and parallel to the horizontal plane. The input end of the first cyclic moving drive mechanism can move relative to its output end in the clutch direction, and the input end of the second cyclic moving drive mechanism can move relative to its output end in the clutch direction. Both the first and second cyclic moving drive mechanisms are equipped with a clutch drive assembly. In the first cyclic moving drive mechanism, the clutch drive assembly is used to drive the input end of the first cyclic moving drive mechanism to interact with the output end, or to drive the input end of the first cyclic moving drive mechanism to disengage from its output end. In the second cyclic moving drive mechanism, the clutch drive assembly is used to drive the input end of the second cyclic moving drive mechanism to interact with the output end, or to drive the input end of the second cyclic moving drive mechanism to disengage from its output end.

[0006] Preferably, the clutch drive assembly includes: a release drive portion and a reset and closing portion; the release drive portion is mounted on the frame and is used to disengage the input end of the first cyclic movement drive mechanism from the output end of the first cyclic movement drive mechanism, or to disengage the input end of the second cyclic movement drive mechanism from the output end of the second cyclic movement drive mechanism; the reset and closing portion is located between the input end of the first cyclic movement drive mechanism and the output end of the first cyclic movement drive mechanism, and is used to maintain the operation of the input end of the first cyclic movement drive mechanism and the output end of the first cyclic movement drive mechanism; or the reset and closing portion is located between the input end of the second cyclic movement drive mechanism and the output end of the second cyclic movement drive mechanism, and is used to maintain the operation of the input end of the second cyclic movement drive mechanism and the output end of the second cyclic movement drive mechanism.

[0007] Preferably, the first and second conveying pull structures are used to move two different types of workpieces to their respective end positions.

[0008] Preferably, a first positioning mechanism is installed on the frame, which is used to position the workpieces to be transported at their respective endpoints.

[0009] Preferably, the first conveying pull structure is equipped with several positioning fixtures, which position the workpiece to be conveyed.

[0010] Preferably, the first positioning mechanism positions the workpiece to be transported using a positioning fixture.

[0011] Preferably, the positioning fixture includes a fixed seat and a floating seat. The fixed seat is fixed to the first or second conveying pull structure, and the floating seat is installed on the fixed seat. The floating seat can float relative to the fixed seat, and the workpiece to be conveyed is positioned on the floating seat.

[0012] Preferably, the floating seat is positioned on the fixed seat by two positioning pins, and the floating seat has a through hole for the positioning pins to pass through, with a gap between the inner wall of the through hole and the outer wall of the positioning pin.

[0013] Preferably, the locating pin has a T-shaped structure, with the larger section of the locating pin located inside the floating seat and unable to detach from the floating seat, while the smaller section of the locating pin passes through the through hole and is threadedly connected to the fixed seat.

[0014] Compared to existing technologies, this invention has the following advantages: This application breaks away from the traditional thinking that a single rotary drive mechanism can only drive one conveying and pulling structure. It enables a single rotary drive mechanism to simultaneously drive the first and second conveying and pulling structures in a cyclical motion, allowing one rotary drive mechanism to move two different types of workpieces to their respective endpoints. Since the two types of workpieces have different sizes, it is highly likely that one type of workpiece will have reached its endpoint while the other type still has a distance to travel. Therefore, a first and second cyclic movement drive mechanism are designed. When the center of one type of workpiece has reached its endpoint, the input end of the corresponding first or second cyclic movement drive mechanism disengages from its output end, while the output end of the corresponding second or first cyclic movement drive mechanism for the other type of workpiece remains connected to the output end of the rotary drive mechanism, thus continuing to wait for the center of the second type of workpiece to reach its endpoint. This allows one rotary drive mechanism to drive two different types of workpieces to their respective endpoints. It saves time on the rotary drive mechanism, reduces energy consumption, and can meet the requirement that the centers of two different types of workpieces to be transported reach their respective endpoint positions.

[0015] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Figures 1 to 6As shown, the present invention provides a dual-line single-motor clutch-driven transmission system, comprising: a first transmission pulling structure 1, a second transmission pulling structure 2, a first cyclic movement driving mechanism 3, a second cyclic movement driving mechanism (not shown in the figure), a frame 4, and a rotary drive mechanism 5; the first transmission pulling structure 1 and the second transmission pulling structure 2 are both cyclically movable and mounted on the frame 4, with a gap between them, and the first transmission pulling structure 1 and the second transmission pulling structure 2 can cyclically move independently of each other, and the transmission directions of the first transmission pulling structure 1 and the second transmission pulling structure 2 are both in a conveying direction; the rotary drive mechanism 5 is mounted on the frame 4, and the first cyclic movement driving mechanism 3 and the second cyclic movement driving mechanism are mounted next to the output end of the rotary drive mechanism 5, the output end of the first cyclic movement driving mechanism 3 is surrounded by the first transmission pulling structure 1, and the output end of the second cyclic movement driving mechanism is surrounded by the second transmission pulling structure 2; The direction perpendicular to the conveying direction and parallel to the horizontal plane is the clutch direction. The input end of the first cyclic moving drive mechanism 3 can move relative to the output end of the first cyclic moving drive mechanism 3 in the clutch direction, and the input end of the second cyclic moving drive mechanism can move relative to the output end of the second cyclic moving drive mechanism in the clutch direction. Both the first cyclic moving drive mechanism 3 and the second cyclic moving drive mechanism are provided with a clutch drive assembly 30. In the first cyclic moving drive mechanism 3, the clutch drive assembly 30 is used to drive the input end of the first cyclic moving drive mechanism 3 to act with the output end of the first cyclic moving drive mechanism 3, or to drive the input end of the first cyclic moving drive mechanism 3 to disengage from the output end of the first cyclic moving drive mechanism 3. In the second cyclic moving drive mechanism, the clutch drive assembly 30 is used to drive the input end of the second cyclic moving drive mechanism to act with the output end of the second cyclic moving drive mechanism, or to drive the input end of the second cyclic moving drive mechanism to disengage from the output end of the second cyclic moving drive mechanism.

[0025] In this application, both the first conveying pull structure 1 and the second conveying pull structure 2 are conveyor chain structures. Of course, the first conveying pull structure 1 and the second conveying pull structure 2 can also be conveyor belt structures, but conveyor chain structures are preferred because the conveying position of the conveyor chain structure is easier to control.

[0026] In this application, the clutch drive assembly 30 includes: a release drive part 301 and a reset closing part 302; the release drive part 301 is mounted on the frame 4, and the release drive part 301 is used to disengage the input end of the first cyclic movement drive mechanism 3 from the output end of the first cyclic movement drive mechanism 3, or to disengage the input end of the second cyclic movement drive mechanism from the output end of the second cyclic movement drive mechanism; the reset closing part 302 is located between the input end of the first cyclic movement drive mechanism 3 and the output end of the first cyclic movement drive mechanism 3, and the reset closing part 302 is used to maintain the operation of the input end of the first cyclic movement drive mechanism 3 and the output end of the first cyclic movement drive mechanism 3; or the reset closing part 302 is located between the input end of the second cyclic movement drive mechanism and the output end of the second cyclic movement drive mechanism, and the reset closing part 302 is used to maintain the operation of the input end of the second cyclic movement drive mechanism and the output end of the second cyclic movement drive mechanism. The reset closing part 302 is used to keep the input end of the first cycle moving drive mechanism 3 or the second cycle moving drive mechanism always connected to the output end of the first cycle moving drive mechanism 3 or the second cycle moving drive mechanism, and the peeling drive part 301 is used to allow the input end of the first cycle moving drive mechanism 3 or the second cycle moving drive mechanism to be disengaged from the output end of the first cycle moving drive mechanism 3 or the second cycle moving drive mechanism.

[0027] A driven shaft and a driven sprocket are mounted on the frame 4. The driven shaft is rotatably mounted on the frame 4, and the driven sprocket is fixed on the driven shaft and surrounded by the first transmission pull structure 1 and the second transmission pull structure 2. The pair of driven shafts and driven sprockets surrounded by the first transmission pull structure 1 are not connected to the two pairs of driven shafts and driven sprockets surrounded by the first transmission pull structure 1, so that the first transmission pull structure 1 and the second transmission pull structure 2 are controlled independently of each other.

[0028] Optionally, both the output end of the first cyclic movement drive mechanism 3 and the output end of the second cyclic movement drive mechanism include: a drive shaft 311, a drive sprocket 312 and a first gear 313. The drive shaft 311 is rotatably mounted on the frame 4. The drive sprocket 312 is fixed on the drive shaft 311. The drive sprocket 312 is surrounded by the end of the first transmission pull structure 1 or the second transmission pull structure 2 away from the driven shaft. The first gear 313 is fixed on the drive shaft 311.

[0029] Optionally, the rotary drive mechanism 5 has two output ends. The rotary drive mechanism 5 includes a motor, sprockets, a chain, and a gear set. The motor output shaft 51 is fixed to one sprocket, and the gear set input end is fixed to the other sprocket. The two sprockets are surrounded by a chain, and the two output ends of the gear set are respectively connected to the output ends of the two rotary drive mechanisms 5. Each output end of the rotary drive mechanism 5 includes an output shaft 51 and a second gear 52. The output shaft 51 is rotatably mounted on the frame 4, and the second gear 52 is fixed in the middle of the output shaft 51.

[0030] Optionally, both the input end of the first cyclic movement drive mechanism 3 and the input end of the second cyclic movement drive mechanism include: a toothed ring sleeve 321 and a third gear 322. The toothed ring sleeve 321 is sleeved outside the second gear 52. The output shaft 51, the toothed ring sleeve 321 and the drive shaft 311 are coaxial. The third gear 322 is fixed on the bottom ring. The third gear 322 can mesh with or disengage from the first gear 313.

[0031] Optionally, the peeling drive unit 301 includes a peeling arm and a peeling cylinder. The peeling arm is fixed to the output end of the peeling cylinder, and the peeling cylinder is mounted on the frame 4. The extension and retraction direction of the peeling cylinder is parallel to the axis of the drive shaft 311, and the peeling arm is engaged in the annular groove formed on the outer wall of the toothed ring sleeve 321.

[0032] Optionally, the reset engagement portion 302 includes a reset spring, or other reset elastic elements. One end of the reset spring is fixed to the outer wall of the output shaft 51, and the other end is fixed to the gear ring sleeve 321. The reset spring is used to maintain the engagement of the third gear 322 and the first gear 313 on the gear ring sleeve 321.

[0033] In this application, the first conveying pull structure 1 and the second conveying pull structure 2 are used to transport two different types of workpieces to their respective end positions.

[0034] In this application, a first positioning mechanism 6 is installed on the frame 4. The first positioning mechanism 6 is used to position the workpieces to be transported at their respective endpoint positions.

[0035] In this application, a plurality of positioning fixtures 7 are installed on the first conveying pull structure 1, and the positioning fixtures 7 position the workpiece to be conveyed.

[0036] In order to position the workpiece to be transported on the positioning fixture 7, the first positioning mechanism 6 positions the workpiece to be transported by positioning the positioning fixture 7.

[0037] The positioning fixture 7 includes a fixed base 71 and a floating base 72. The fixed base 71 is fixed to the first conveying pull structure 1 or the second conveying pull structure 2. The floating base 72 is installed on the fixed base 71 and can float relative to the fixed base 71. The workpiece to be conveyed is positioned on the floating base 72. Since the position of the positioning fixture 7 after reaching the output end of the first conveying pull structure 1 has a very small difference from the required position, in order to avoid this small difference, the floating base 72 is designed to float relative to the fixed base 71. The floating range is very small. When the floating base 72 can float, the output end of the first positioning mechanism 6 presses on the floating base 72, so that the floating base 72 adapts to the output end of the first positioning mechanism 6, thereby enabling the floating base 72 to reach the required position and improving the accuracy of the final conveying of the irregular movable block 81.

[0038] Optionally, the first positioning mechanism 6 includes a positioning cylinder 61 and a positioning head 62. The positioning cylinder 61 is mounted on the frame 4, and the output end of the positioning cylinder 61 is fixed to the positioning head 62. The positioning head 62 is the output end of the first positioning mechanism 6. The positioning head 62 has a "mountain" shaped structure. The first mountain-shaped contact surface formed by the positioning head 62 is used to closely fit with the second mountain-shaped contact surface formed on the floating seat 72. The close contact between the first mountain-shaped contact surface and the second mountain-shaped contact surface can enable the first positioning mechanism 6 to fully position the floating seat 72 and reduce the position error of the floating seat 72 after being conveyed by the first conveying and pulling structure 1.

[0039] Preferably, the floating seat 72 is positioned on the fixed seat 71 by two positioning pins 73. The floating seat 72 has a through hole through which the positioning pins 73 pass, and there is a gap between the inner wall of the through hole and the outer wall of the positioning pin 73. The gap design allows the floating seat 72 to float in all directions of 360°, ensuring that the floating seat 72 can cooperate with the positioning head 62 and eliminate the positional error of the floating seat 72 after being conveyed by the first conveying and pulling structure 1.

[0040] Preferably, the locating pin 73 has a T-shaped structure, with the larger section of the locating pin 73 located inside the floating seat 72. The larger section of the locating pin 73 cannot be detached from the floating seat 72, while the smaller section of the locating pin 73 passes through the through hole and is threadedly connected to the fixed seat 71. The locating pin 73 serves both to mount the floating seat 72 onto the fixed seat 71 and to limit the floating range.

[0041] Optionally, the positioning fixture 7 on the first conveying pull structure 1 is used to position the irregular movable block 81. The second conveying pull structure 2 conveys the annular bushing 82 and does not require the positioning fixture 7. A second positioning mechanism 9 is provided next to the output end of the second conveying pull structure 2. The second positioning mechanism 9 is a plate-shaped structure and has a V-groove. The V-groove positions the annular bushing 82.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
