Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more particularly to a following flipping component and a conveying mechanism having the component. Background Technology

[0002] In the fields of automated conveying and precision tooling transmission, workpieces often need to simultaneously perform self-flipping, carrier plate opening and closing, and workpiece alignment actions while being continuously fed in a straight line. Currently, the mainstream implementation schemes mostly adopt a split structure with a linear drive unit and an independent rotary drive component. Generally, the rotary action is controlled by a rotary cylinder, a rotary motor, and a multi-link swing arm, with the linear and flipping drives arranged independently.

[0003] Such split-structure components are scattered, requiring numerous supporting pipes, wiring, and mounting brackets, making assembly cumbersome, space-consuming, and resulting in high equipment processing and assembly costs. To achieve timing matching between linear feed and tilting actions, existing mechanisms generally require the addition of position sensors and rely on two sets of drives that start and stop in a time-sharing manner using a programmable electronic control program. The synchronization effect is greatly affected by the accuracy of the electronic control components and the stability of signal transmission, and during operation, faults such as insufficient tilting angle, delayed action, jamming, and misalignment are prone to occur, resulting in poor repeatability and positioning stability.

[0004] Meanwhile, traditional swing arm and articulated tilting mechanisms naturally have assembly gaps. Under long-term high-frequency reciprocating conditions, the articulated points wear continuously, and the gaps gradually increase, which can easily lead to loosening of components, operational deviation, and limited service life of the equipment. Existing structures cannot meet the requirements of miniaturized layout, electronically controlled synchronous tilting, and long-term high-precision and stable operation. Therefore, there is an urgent need for an integrated mechanism that achieves automatic tilting by relying on pure mechanical guidance. Summary of the Invention

[0005] This invention provides a follow-up flipping component, an integrated flipping mechanism that can automatically and synchronously complete the flipping action during linear movement without the need for independent rotation drive, thereby solving the technical defects of existing technologies such as complex structure, high cost, poor synchronization and insufficient stability.

[0006] The technical solution adopted in this invention to solve the technical problem is as follows:

[0007] A following flip component, comprising:

[0008] A flip guide base, wherein a guide groove extending along its length is provided on the flip guide base;

[0009] A flipping component, wherein at least two guide pins are provided on the flipping component, and the guide pins are slidably embedded in the guide groove;

[0010] The guide groove forms a preset angle with the length direction of the flipping guide base, and the guide pin slides with the groove wall of the guide groove. When the flipping component moves linearly along the length direction of the flipping guide base, the guide pin is constrained by the groove wall of the guide groove, causing the flipping component to move linearly along the flipping guide base while rotating around its own axis.

[0011] Further technology of the present invention:

[0012] Preferably, the guide groove is one or more oblique or zigzag grooves continuously arranged along the length direction.

[0013] Preferably, multiple guide grooves are arranged to intersect and connect with each other, and the inclination direction and bending trajectory of each guide groove are matched with each other to form a continuous composite guide trajectory.

[0014] Preferably, the guide groove includes a forward inclined section and a reverse inclined section, the forward inclined section and the reverse inclined section are connected end to end to form a broken line structure, and a smooth transition bend is formed between adjacent groove sections to limit the sliding trajectory of the guide pin.

[0015] Preferably, four guide pins are fixedly provided on the flipping component. The four guide pins are evenly distributed on the assembly end face of the flipping component in a centrally symmetrical manner, and the four guide pins are slidably embedded in the interior of multiple guide grooves in a one-to-one correspondence.

[0016] Preferably, the four guide pins are divided into two symmetrical pin groups, and the two groups of pins are respectively embedded in the intersecting guide grooves. The outer circumferential surface of each guide pin is always in contact with the two side walls of the corresponding guide groove.

[0017] Preferably, the width of the guide groove is adapted to the outer diameter of the guide pin, and the guide pin and the guide groove are in a clearance-free sliding fit.

[0018] The present invention also provides a conveying mechanism, including a frame, a drive assembly, a linear guide base, a tilting guide base, and a tilting component;

[0019] The linear guide base and the flip guide base are arranged on both sides of the frame. The linear guide base is provided with a transverse guide groove extending along its length direction, and the transverse guide groove of the flip guide base and the guide groove of the flip guide base are connected without gap to form a ring guide track.

[0020] The flipping guide base has flipping components in both the guide groove and the transverse guide groove. The flipping components are provided with first connecting rods. A first material support plate is provided between the first connecting rods on both sides of the frame, and the first connecting rod is located on the right side of the first material support plate.

[0021] A connecting mechanism is provided between two adjacent first links, and several flipping parts are connected by the connecting mechanism to form a closed-loop chain.

[0022] The connecting mechanism is provided with a second connecting rod, and a second material support plate is provided between the second connecting rods on both sides of the frame, with the second connecting rod located on the left side of the second material support plate; the first connecting rod is provided with a driving tooth, and the second connecting rod is provided with a driven tooth, with the driving tooth meshing with the driven tooth;

[0023] When the flipping component passes through the guide groove of the flipping guide base, the flipping component rotates 90° clockwise, and the first connecting rod drives the second connecting rod to rotate 90° counterclockwise through gear meshing transmission, and the material plate surfaces of the first material support plate and the second material support plate are opposite to each other.

[0024] When the flipping component passes through the guide groove of the flipping guide base again, the flipping component rotates 90° counterclockwise, and the first connecting rod drives the second connecting rod to rotate 90° clockwise through gear meshing transmission, and the material plate surfaces of the first material support plate and the second material support plate separate.

[0025] The drive assembly is mounted on the frame and is used to drive the flipping component to reciprocate along the annular guide track.

[0026] Furthermore, the drive assembly includes a drive motor mounted on a frame. The frame has a drive wheel and a driven wheel at both ends. The drive wheel is connected to the output shaft of the drive motor. The drive wheel has slots evenly distributed around its circumference for receiving the connecting mechanism. The rotation of the drive wheel drives the connecting mechanism to move, thereby driving the flipping component to reciprocate along the annular guide track.

[0027] Furthermore, by changing the inclination angle of the guide groove and the direction of the groove's broken line, the flipping angle of the flipping component and the clockwise and counterclockwise flipping direction can be controlled.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] This invention utilizes the spatial geometry of the guide groove to convert the linear displacement of the flipping component into rotational torque through the inclined thrust of the guide pin groove wall. It achieves linear and rotary composite motion through a purely mechanical structure, eliminating the need for dedicated rotary drive components such as independent rotary cylinders and servo rotary modules, and reducing the need for supporting air sources, electrical wiring, and auxiliary power components. The resulting machine has fewer parts and a simplified assembly process, significantly reducing the costs of parts processing, overall assembly, and the procurement of supporting electrical control components, thus facilitating miniaturization and lightweight design.

[0030] The linear conveying and flipping motion relies on the rigid coupling of the closed structure of the guide groove and guide pin. The motion sequence is physically limited by the guide groove trajectory, eliminating the need for position sensors and time-sharing control programs to coordinate the actions. This completely avoids problems such as flipping lag, opening and closing misalignment, and asynchronous actions caused by electrical control signal delays, sensor failures, and program errors. The entire stroke is rigidly limited by the groove wall, and the start and stop of flipping and the size of the rotation angle are uniformly controlled. The mechanism has high repeatability and positioning accuracy, which can meet the requirements of precision workpiece conveying and mold closing conditions.

[0031] The guide pin outer diameter and guide groove width are precisely matched to achieve a clearance-free sliding fit. Furthermore, the four sets of guide pins are symmetrically embedded in the cross guide grooves, providing multi-point synchronous limiting constraints on the degrees of freedom of the flipping component in all directions, suppressing radial movement and offset during operation. Compared to traditional articulated or swing-arm type clearance transmission structures, this solution has extremely small movement clearances, making it less prone to component looseness and misalignment during high-frequency continuous operation. The overall force is distributed across multiple guide pin contact surfaces with the groove walls, resulting in low single-point wear loads, low failure rate during long-term high-speed cyclic operation, and effectively extending the overall machine's service life.

[0032] The flipping parameters are entirely determined by the inclination angle of the guide groove's inclined section, the position of the inflection point of the broken line, and the arrangement of the forward and reverse groove sections. The flipping angle and clockwise or counterclockwise rotation can be flexibly adjusted simply by machining changes to the direction and contour of the guide groove, without requiring modifications to core transmission components such as connecting rods, gears, and drive motors. The same main conveyor frame and transmission parts can be adapted to various workpieces with different flipping and opening requirements by replacing the flipping guide base with different groove types. The equipment has a short modification and debugging cycle and excellent versatility.

[0033] All the flipping components are connected in series via a connecting mechanism to form a closed loop chain. The entire machine relies on a single drive motor in conjunction with the main and driven wheels to drive the entire line in a cyclical manner, eliminating the need for segmented, multi-point drive layouts and reducing the number of power system components. The drive points are centrally located at the end of the frame, making lubrication, maintenance, and troubleshooting points more concentrated, reducing daily maintenance workload and lowering the investment in equipment maintenance in the later stages.

[0034] Relying on the precise meshing transmission between the first connecting rod's active gear and the second connecting rod's driven gear, the rotational motion of the single-sided flipping part can be synchronously and in reverse transmitted to the two sets of material support plates. The gear pair transmission ratio is constant, and the opening and closing strokes and flipping amplitudes of the two support plates are strictly matched, eliminating the phenomenon of the single-sided support plate not moving in place or misalignment during opening and closing, thus ensuring the workpiece's mold closing and docking accuracy.

Detailed Implementation

[0047] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0048] like Figure 1-2 This embodiment provides a specific structure of the accompanying flipping component, which includes a flipping guide base 10 and a flipping component 12.

[0049] A composite guide groove 11 is opened on the surface of the flip guide base 10. The guide groove 11 is composed of a forward inclined section 14 and a reverse inclined section 15 that are smoothly connected end to end to form a zigzag channel. Multiple guide grooves 11 are arranged in a cross-connection manner and spliced ​​together to form a continuous composite guide trajectory.

[0050] Four guide pins 13 are symmetrically fixed at the center of the assembly end face of the flipping component 12. The four guide pins 13 are divided into two symmetrical pin groups, which are embedded into the cross-shaped guide grooves 11. The outer circumference of the guide pins 13 and the two side walls of the guide grooves 11 are in close contact throughout the entire length of the groove. The width of the guide grooves 11 matches the outer diameter of the guide pins 13, and the two are slidably assembled without gaps. The guide grooves 11 are positioned at a fixed angle relative to the length of the flipping guide base 10. When the flipping component 12 slides linearly along the length of the base, the guide pins 13 are constrained by the groove walls, enabling it to move forward in a straight line while rotating around its own axis. A single 90-degree clockwise flip can be completed along the guide path.

[0051] It should be noted that in this embodiment, the width of the guide groove is adapted to the outer diameter of the guide pin, and the guide pin and the guide groove are in a clearance-free sliding fit.

[0052] An external driving force drives the flipping component 12 to move linearly along the axial direction of the flipping guide base 10. The guide pin 13 is limited inside the guide groove 11 and slides accordingly. Utilizing the inclined spatial configuration of the guide groove 11 relative to the direction of travel, the groove wall continuously applies a lateral component force to the guide pin 13, converting the linear displacement force of the flipping component 12 into a rotational torque around the central axis. The zigzag groove formed by the forward inclined section 14 and the reverse inclined section 15 can switch the direction of the lateral force, thereby changing the flipping direction. The four guide pins 13 arranged in a centrally symmetrical manner provide multi-point limiting, restricting the redundant radial and circumferential degrees of freedom of the flipping component 12, and ensuring that the motion trajectory is completely determined by the contour of the guide groove 11.

[0053] It achieves linear and rotary composite motion by relying on a purely mechanical groove structure, without the need to install an independent rotary drive component; the gapless fit combined with multi-point symmetrical limit ensures no play or offset during operation and high consistency of repeated flipping angles; by only modifying the tilt angle and bending position of the forward inclined section 14 and the reverse inclined section 15, the flipping stroke and rotation angle can be flexibly adjusted without changing the main structure of the parts, thus adapting to multiple specification process requirements.

[0054] like Figure 3 A specific flipping path for a flipping component in a traveling flipping assembly, wherein the guide pin of the flipping component is constrained by the groove wall of the guide groove, causing the flipping component to move linearly along the flipping guide base while rotating around its own axis, specifically as follows: Figure 3 The sequence goes from white to yellow to red to cyan to blue, ultimately achieving a 90° clockwise rotation.

[0055] like Figure 4-10 This embodiment is based on the aforementioned flipping component to form a conveying mechanism, which is mainly used for ice cream filling and two-half mold closing molding operations. The structure includes a frame 16, a drive component, a linear guide base 17, a flipping guide base 10 and multiple sets of flipping components 12.

[0056] Linear guide bases 17 and flipping guide bases 10 are respectively arranged on the left and right sides of the frame 16. The linear guide base 17 has a transverse guide groove 19, which is seamlessly connected with the guide groove 11 to form a complete circular guide track. The flipping components 12 are connected end to end by the connecting mechanism 22 to form a closed-loop chain.

[0057] A single-piece flipping component 12 is fixedly mounted with a first connecting rod 20, and a first material support plate 21 is erected between the two first connecting rods 20 on the same side of the frame; a second connecting rod 23 is fixed on the connecting mechanism 22, and a second material support plate 24 is erected between the two second connecting rods 23 on both sides. A driving gear 25 is machined on the outer side of the first connecting rod 20, and a driven gear 26 is machined on the outer side of the second connecting rod 23. The driving gear 25 and the driven gear 26 mesh with each other for transmission.

[0058] The drive assembly consists of a drive motor 27, a drive wheel 28, and a driven wheel 29. The drive motor 27 is mounted on the frame 16, and its output shaft is connected to the drive wheel 28. The drive wheel 28 has several slots 30 on its circumference, and the slots 30 are fitted with a connecting mechanism 22.

[0059] The drive motor 27 outputs torque to drive the drive wheel 28 to rotate. Relying on the meshing connection mechanism 22 of the slot 30, it drives the ring chain composed of all the turning parts 12 to circulate in a closed loop along the ring track composed of the transverse guide groove 19 and the guide groove 11. When the turning parts 12 are moving straight in the transverse guide groove 19, there is no rotation. The two sets of material support plates maintain the separate feeding condition. After entering the area of ​​the guide groove 11, the turning parts 12 are forced to rotate by the inclined trajectory of the guide groove 11. The rotational motion of the turning parts 12 is transmitted in the opposite direction by the gear pair of the drive tooth 25 on the first connecting rod 20 and the driven tooth 26 on the second connecting rod 23 in a proportional manner, so that the first material support plate 21 and the second material support plate 24 can be closed in the same direction at the same time. When passing through the reverse groove section of the guide groove 11 again, the turning parts 12 rotate in the opposite direction, and the gear pair is linked in the opposite direction to realize the separation of the support plates and the material falling.

[0060] During the unloaded stage, the flipper 12 moves straight in the transverse guide groove 19, with the two support plates remaining separate. The operator places the ice cream plastic trays onto the surfaces of the first material support plate 21 and the second material support plate 24 respectively. The trays pass through the filling station in sequence to complete the filling. When the trays are fully loaded, they move to the flipping guide base 10. The guide groove 11 constrains the flipper 12 to rotate 90 degrees clockwise. Through gear meshing, the first connecting rod 20 rotates clockwise and the second connecting rod 23 rotates 90 degrees counterclockwise. The surfaces of the first material support plate 21 and the second material support plate 24 close towards each other, and the trays on both sides are joined to complete the ice cream mold closing.

[0061] As the molded finished product continues to move around the chain, when it passes the flipping guide base 10 again, the flipping part 12 is limited by the reverse groove section and rotates 90 degrees counterclockwise. The two sets of connecting rods are reset in the opposite direction, the two support plates are separated again, the support plates are arranged downwards, and the formed ice cream falls off by its own weight to complete the collection.

[0062] In actual production, the inclination angle and zigzag direction of the guide groove 11 can be changed as needed, and the flipping angle and rotation direction of the flipping part 12 can be flexibly adjusted to adapt to the production of ice cream of different specifications.

[0063] It should be noted that the entire machine uses only a single drive motor 27 to realize the entire process of conveying, flipping, and opening and closing of the support plate, simplifying the power system configuration; the conveying, flipping, and opening and closing actions are forcibly linked by the mechanical structure, eliminating the need for station detection sensors and timing control programs, ensuring synchronous and stable actions, and preventing failures such as asynchronous opening and closing of the support plate or misalignment of the mold; the integrated design of the circular track results in a compact equipment layout, which is conducive to the miniaturization of the production line; the opening and closing range can be changed by modifying the trough shape, resulting in low equipment modification and debugging costs.

[0064] The illustrations provided in this embodiment are only intended to illustrate the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0065] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
