Description

Technical Field

[0001] The invention relates to a horizontal bidirectional module loop line, belonging to the technical field of automated conveyor lines. Background Art

[0002] Industrial automation is the widespread adoption of automatic control and adjustment devices in industrial production to replace manual operation of machines and systems. Under automated industrial production conditions, humans only indirectly oversee and supervise the machines. Industrial automation can be categorized by its stage of development: Semi-automation, which involves partial use of automatic control and automated devices, while manual operation of the machines is still the sole focus. Full automation, which means that all production processes, including loading, unloading, and loading and unloading, no longer require direct human intervention. Instead, machines continuously and repeatedly produce individual products or batches of products automatically.

[0003] In automated industrial production, conveyor lines for material turnover are indispensable. There are two types of conveyor lines: one is distance material transportation, and the other is workstation switching conveyor turnover. This case is aimed at workstation switching conveyor turnover. Workstation switching conveyor turnover requires high conveying accuracy to ensure that the relative position of materials conveyed to each workstation is accurate. Generally, there will be multiple material carriers, and the material carriers are aligned with the workstation switching to meet the production requirements of each process.

[0004] Currently, station switching conveyor lines mainly include rotary tracks and rotating pallets. The rotary pallet realizes the station switching of the carrier through indexing rotation control. However, the number of carriers it provides and the space for processing equipment at each station are insufficient to meet the switching requirements of more stations. At the same time, the number of carriers cannot be expanded. The rotary track generally adopts a dual-track operation mode, and a switching station operation mechanism is constructed at both ends of the dual track to meet the circulation operation requirements of the carrier on the dual track. During the dual-track operation, the carrier on a single track needs to be independently operated and controlled, which makes it difficult to ensure the operation accuracy and stability. In addition, the switching station operation mechanism at both ends is relatively complex, takes up more space and is costly.

[0005] Publication No. JP2017217730A discloses a pallet conveying device, which uses a bottom toothed belt to achieve linear transmission of the pallet and a swinging part to achieve pallet position switching. This method can achieve cyclic operation, but after the swinging part switches the pallet position, it is still necessary to perform power docking with the linear conveyor line. The power docking and the bottom toothed belt docking will have precision losses, and it also occupies a large space.

[0006] In response to this situation, the applicant filed a Chinese invention patent with authorization announcement number CN113666095B, ​​which discloses a circular rotary conveyor line. Referring to the drawings in the specification, it discloses a circular rotary conveyor line assembled from multiple linked linear conveying units and rotary units. The two rotary units can realize the rotational conveying of the revolving seat, and at the same time meet the requirements of synchronous linear displacement of the revolving seat during the eccentric rotation and turnover process, so that the revolving seat can be continuously docked and conveyed with the linked linear conveying unit, so that the space is compact and the operation is smooth.

[0007] However, during the assembly and debugging process of this circular rotary conveyor line, high-precision docking between the linked linear conveying unit and the rotary unit is required, and corresponding adjustment and positioning need to be performed through the base. The relative error generally needs to be debugged to ±0.1mm. In addition, since the multiple linked linear conveying units can be increased or decreased, the mutual adjustment error also requires high-precision debugging, resulting in a very large debugging workload. At the same time, when performing linear segment transportation, there is linear speed coordination and cooperation, and follow-up software debugging is generally used, which is also relatively difficult. During the actual operation test, since the revolving seat of each linear segment is independently or speed-matched, the positioning accuracy of the revolving seat is also easily lost. Summary of the Invention

[0008] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art. In view of the problems in traditional circular production lines where it is difficult to adjust the relative assembly accuracy when assembling the units into a line and the follow-up software control is difficult and easily leads to loss of work station accuracy, a horizontal bidirectional module loop is proposed.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] The present application will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to explain the relevant inventions and are not intended to limit the inventions. It should also be noted that, for ease of description, only portions relevant to the relevant inventions are shown in the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application may be combined with each other.

[0047] The present invention provides a horizontal bidirectional module loop line, such as Figures 1 to 12 As shown, it includes an integrated loop base 1, on which a bidirectional linear track segment 2, a plurality of revolving seats 3, and two drive switching position assemblies 4 arranged at both ends of the bidirectional linear track segment 2 are provided.

[0048] like Figure 4 and Figure 5 As shown, the bidirectional linear track segment 2 includes two linear track segment guide rails 20 arranged in parallel, and a plurality of revolving seats 3 arranged in abutment with each other in a row are slidably coupled to any linear track segment guide rail 20 .

[0049] like Figures 6 to 8 As shown, the drive switching position assembly 4 includes an assembly carrier plate 40 detachably arranged on the integrated loop base, a linear drive mechanism 5 and a rotation switching position mechanism 6 arranged on the assembly carrier plate 40 .

[0050] like Figure 6 and Figure 8 As shown, the linear drive mechanism 5 includes two linear drive rails 51 arranged on the assembly carrier plate and spliced ​​one-to-one with the linear segment guide rails, a linear conveying drive source 52 arranged between the two linear drive rails 51, a revolving seat 3 is slidably connected to any linear drive rail, the linear conveying drive source is arranged between the two revolving seats, and a transmission matching mechanism 7 is provided between the linear conveying drive source and any revolving seat.

[0051] like Figure 9 and Figure 10 As shown, the rotary switching position mechanism 6 includes a rotary switching platform 61 with rotary displacement arranged on the assembly carrier, a rotary drive source 62 for driving the rotary displacement of the rotary switching platform, and a cooperating linear conveying drive source 63 running through the rotary switching platform. The rotary switching platform is provided with two switching position guide rails 611 arranged in one-to-one correspondence with the linear drive guide rails. A revolving seat 3 is slidably connected to any switching position guide rail, and a transmission matching mechanism 7 is provided between the cooperating linear conveying drive source and the revolving seat.

[0052] The linear conveying drive sources of the two drive switching position assemblies and the matching linear conveying drive sources communicate with each other and are linked at the same speed.

[0053] Specific implementation process and principle description:

[0054] The drive switching position assembly 4 is used to realize the assembly design of linear drive and rotational drive, that is, the integrated loop base 1 can meet the needs of mounting two drive switching position assemblies 4, thereby realizing high-precision assembly and matching between the linear rail section guide rail 20 and the drive switching position assembly 4. While the operating accuracy of the revolving seat 3 is guaranteed, its drive is also relatively reliable and smooth.

[0055] Specifically, the integrated loop base 1 is processed and produced according to the number of workstations of the revolving seat 3 required by the linear rail segment guide rail 20, and its two linear rail segment guide rails 20 are fully loaded with revolving seats 3 arranged in a linear abutment relationship, and the length of the linear rail segment guide rail 20 is an integer multiple of the linear displacement direction dimension of the revolving seat 3.

[0056] After the drive switching position assembly 4 is mounted and spliced, the linear drive guide rail 51 and the linear rail segment guide rail 20 are relatively aligned and assembled with high precision to form a continuous track.

[0057] During the driving operation, initially, the switching position guide rail 611 on the rotating switching table 61 is spliced ​​and aligned one by one with the linear driving guide rail, and the linear conveying drive source 52 synchronously drives the two revolving seats 3 that are coordinated with it. When it is rotated and driven, the two revolving seats 3 on both sides are synchronously displaced in both directions, and the revolving seats it drives will produce continuous abutment and push on the revolving seats on the bidirectional linear rail segment 2, thereby realizing the bidirectional non-active power conveying drive of the bidirectional linear rail segment 2.

[0058] At this time, the rotatable seat 3 on the two switching position guide rails 611 of the rotary switching position mechanism 6 realizes the drive of one side in and one side out, that is, cooperates with the linear conveying drive source 63 to realize the bidirectional drive of the rotatable seat 3. When one rotatable seat 3 completely enters the switching position guide rail 611, the other rotatable seat 3 will completely move out of the switching position guide rail 611, and the moved-out switching position guide rail 611 will produce transmission cooperation with the linear conveying drive source 52. At this time, the linear conveying drive source 52 and the coordinated linear conveying drive source 63 stop conveying, and the rotatable seat on the bidirectional rail segment 2 is driven. In response to the operation of each workstation, the rotation drive source 62 drives the rotary switching table to rotate by utilizing the operation gap, and the revolving seat on it performs a 180° position rotation. To explain its rotation, the transmission matching mechanism 7 only produces linear displacement under the rotation drive of the linear conveying drive source 52 and the matching linear conveying drive source 63. Under the rotational displacement of the rotary switching table, the circumferential displacement of the revolving seat 3 and the torque-free matching linear conveying drive source 63 are relative rotational rolling, so the revolving seat 3 does not produce relative linear displacement on the switching position guide rail 611.

[0059] Such a circular operation satisfies the circular linear transport turnover of the horizontal bidirectional module loop. It should be noted that the linear conveying drive sources of the two drive switching assemblies and the matching linear conveying drive sources communicate with each other and are linked at the same speed. The synchronous forward or reverse rotational displacement can realize the control of bidirectional conveying. The communication synchronous control belongs to the existing technology and will not be repeated here.

[0060] It should be noted that the revolving seat 3 on the bidirectional linear rail segment 2 adopts a transmission without autonomous power. It only requires the abutment and fitting accuracy between the revolving seats 3 to be met. Under the abutment power displacement of the external revolving seat 3, it can ensure that its displacement accuracy is reliable and stable. Compared with the existing technology, there is no need for follow-up control of the active rotation source, and there is no error between relative power sources. At the same time, the relative position accuracy of the revolving seat 3 can be fully guaranteed.

[0061] In addition, the integrated loop base 1 can perform relatively high-precision position assembly control on the bidirectional linear rail segment 2 and the drive switching position assembly 4, without the need for relative position precision adjustment and control coordination. The drive switching position assembly 4 is an integrated assembly design, and only the drive switching assembly 4 itself needs to be precision adjusted. After assembly, it can meet the switching position precision requirements of the revolving seat 3, reducing manufacturing costs, assembly costs, and debugging costs.

[0062] In a specific embodiment, Figures 3 to 5 As shown, the integrated loop base 1 is provided with an assembly carrier 10 for carrying the drive switching position assembly, the assembly carrier 10 is provided with a carrier plate positioning support portion 11 for carrying the assembly carrier plate, a linear drive positioning window 12 arranged on the carrier plate positioning support portion for cooperating with the linear drive mechanism, and a rotational switching positioning window 13 for cooperating with the rotational switching position mechanism.

[0063] The linear drive mechanism 5 includes a linear conveying drive source carrier block arranged at the bottom of the assembly carrier plate for cooperating with the linear drive positioning window. The linear conveying drive source is arranged on the linear conveying drive source carrier block. The illustration and marking of the linear conveying drive source carrier block are omitted in the accompanying drawings.

[0064] The rotary switching mechanism 6 includes a rotary carrier base 64 arranged at the bottom of the assembly carrier plate for cooperating with the rotary switching positioning window, and is arranged on the rotary carrier base in conjunction with the linear conveying drive source and the rotary drive source.

[0065] First, the relative precision control of the linear drive mechanism 5 and the rotary switching position mechanism 6 is achieved through the assembly carrier plate 40 to ensure that the relative cooperation of the linear drive mechanism 5 and the rotary switching position mechanism 6 is reliable and stable, and there is no need to adjust the assembly position of the two. Therefore, the drive debugging of the assembly can meet the relative control precision of its linear operation and rotary operation.

[0066] The assembly carrier 10 satisfies the mounting accuracy requirements of the drive switching assembly 4, and realizes high-precision matching between the drive switching assembly 4 and the bidirectional linear track segment 2, thereby ensuring assembly accuracy and follow-up displacement accuracy.

[0067] In a specific embodiment, Figure 11 and Figure 12As shown, at both ends of the linear conveying direction of any revolving seat 3, there are respectively provided with abutment fitting parts 31, which are detachably provided on the revolving seat 3. The abutment fitting parts 31 are abutment rollers 32 with free rotation displacement and vertically provided with their axes.

[0068] Specifically, the revolving seat 3 generally has a revolving seat carrier plate, which is used to carry the workpiece carrier. The revolving seat 3 itself has certain machining accuracy requirements. When unpowered abutment continuous conveying is adopted, the matching size accuracy of the revolving seat 3 is required to be higher so as to meet the relative position accuracy.

[0069] To address this situation, in this embodiment, the design of the abutment roller 32 is adopted, that is, the two adjacent rotatable seats 3 are relatively abutted and matched through the abutment roller 32. Under the limitation of the sliding matching guide accuracy, the abutment roller 32 can achieve high-precision point-to-point abutment matching. By differentially assembling the abutment roller 32 in size, the accuracy of the abutment transmission of the rotatable seats 3 on the entire production line can be met. At the same time, the abutment of the abutment roller 32 has relatively less wear and tear, and can maintain the high-precision operation of the bidirectional linear rail section 2 without active power for a long time, thereby reducing maintenance and repair costs.

[0070] In a specific embodiment, the transmission cooperation mechanism 7 includes a linear transmission part 71 provided on the side wall of the epicyclic seat, and a rotation cooperation driving part 72 for transmission cooperation with the linear transmission part.

[0071] In a specific application, the linear transmission part is a rack, and the rotationally mating driving part is a rotating shaft disk that meshes with the rack for transmission. The rotating shaft disk includes a rotating shaft disk body and a plurality of circumferentially evenly distributed driving vertical rods arranged on the rotating shaft disk body.

[0072] This design is an existing technology, that is, the transmission of the rack can be achieved by rotating the shaft disk. This transmission is mainly used to accurately coordinate the torque transmission and maintain the control of transmission accuracy in the case of multiple power sources. Its structure is relatively simple, which is conducive to torque monitoring and positioning.

[0073] In another specific embodiment, the linear transmission part is a friction plate, and the rotationally coupled driving part is a friction roller that is frictionally driven by the friction plate.

[0074] Specifically, in this embodiment of a horizontal bidirectional modular loop, the bidirectional linear track section 2 lacks active power, eliminating the need for high-precision torque transmission monitoring and precise software adjustments. In this case, precision control resides directly in the linear drive mechanism 5. Simply providing position monitoring for the epicyclic seat 3 on the linear drive guide rail 51 is sufficient to meet overall precision requirements. Precision control can also be achieved through the dynamic coordination of a rack and a rotating shaft, without limiting the scope of this discussion to the transmission coordination mechanism 7.

[0075] In a specific embodiment, a switching position monitoring sensor 612 for monitoring the relative position between the linear drive guide rail and the switching position guide rail is provided on the rotary switching platform 61 .

[0076] By switching the position monitoring sensor 612, high-precision control of its 180° rotation position can be achieved, ensuring that the rotating swivel seat 3 transmits displacement reliably and stably.

[0077] In a specific embodiment, a position monitoring sensor for monitoring the driving position of the linear conveying drive source and / or the revolving seat is provided on the assembly carrier plate 40 .

[0078] Specifically, the position monitoring sensor can be used for position monitoring of the revolving seat 3, or for torque position monitoring of the linear conveying drive source. When a higher-precision torque transmission is adopted, monitoring the torque of the linear conveying drive source can meet the relative position control requirements of the revolving seat 3. When a power drive without precise torque output is adopted, the position monitoring of the revolving seat 3 can meet the relative position accuracy control requirements of the entire revolving seat 3, which makes debugging, control and other operations more convenient.

[0079] In a specific embodiment, the integrated loop base 1 is a gantry frame formed by an integrated machine, and a detachable support pile body 14 is provided at the bottom of the gantry frame.

[0080] Specifically, the gantry is processed and formed in one piece. After processing, the mounting accuracy of the bidirectional linear rail segment 2 and the relative position of the drive switching assembly 4 are controlled with high precision, which is easy to assemble and match. The processing cost is also controlled. When performing differentiated production line changes, only the drive switching assembly 4 needs to be replaced, and the support pile body 14 is used for adjusting the height of the production line to meet the requirements of the ring line support erection.

[0081] From the above description, it can be found that the high-precision assembly and construction of the production line can be achieved through the integrated loop base, ensuring the alignment accuracy of the drive switching position assembly and the bidirectional linear track segment, reducing assembly costs and debugging costs, and eliminating the relative errors between independent power sources. The combination of the drive switching position assembly and the unpowered bidirectional linear track segment can meet the needs of bidirectional circulation transportation while ensuring the relative position accuracy of the turnover seat. It can achieve high-precision abutment fit, with relatively little wear, greatly extending the effective service life of the loop operation, and is easy to maintain, repair, and operate and debug. The integrated loop base and the drive switching position assembly can realize integrated production assembly, with reliable and stable relative assembly accuracy and high economic value.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
