Description

Technical Field

[0001] This invention belongs to the field of multistage pump manufacturing, specifically relating to a vertical multistage pump production line. Background Technology

[0002] The production of vertical multistage pumps includes assembly, testing, post-processing, and packaging. In the industry, vertical multistage pump production is typically carried out on the workshop floor in areas divided according to process zones, making process-oriented management difficult and resulting in chaotic production control. Furthermore, the assembly of vertical multistage pumps is generally done on the ground, with operators assembling the various components from bottom to top. As the height of the vertical multistage pump increases during assembly, operators need to bend over initially and then stand on tiptoe later, which is extremely inconvenient, leading to low assembly efficiency and poor assembly quality.

[0003] Due to the wide variety of models and types of vertical multistage pumps, production lines for vertical multistage pumps are generally compatible production lines. The vertical multistage pumps being assembled range in height from 700mm to 2000mm and in weight from 50kg to 450kg. The assembly of these pumps requires manual labor. Therefore, a specialized machine and production line for vertical multistage pumps that can be manually operated is needed to reduce the labor intensity of workers, standardize the production process of vertical multistage pumps, and improve the assembly quality of vertical multistage pumps.

[0004] Therefore, how to provide an assembly line for vertical pump production that organically links assembly, testing, rework, post-processing, and packaging, thereby breaking away from traditional production methods, standardizing the production process of vertical multistage pumps, and reducing the labor intensity of workers, has become a problem that needs to be solved by those skilled in the art.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The production line of this invention covers assembly, testing, post-processing, and packaging, organically linking these processes together. It boasts a high degree of automation, breaks away from traditional production methods, standardizes the production process of vertical multistage pumps, reduces the labor intensity of workers, and improves the production efficiency of vertical multistage pumps. Given the wide variety of vertical multistage pump models and types produced by manufacturers, this invention is compatible and can be matched with multiple models of vertical multistage pumps for co-production.

[0018] 2. This invention transforms the production process of vertical multistage pumps from traditional ground-based operations to online operations. By installing electric roller supports and electric rollers, it can be used in conjunction with a conveyor line, thereby standardizing and streamlining the production process of vertical multistage pumps and improving the overall assembly level of the vertical multistage pump manufacturing industry. The lifting device can accommodate the assembly of vertical multistage pumps at different heights, meeting the needs of assembling multiple varieties and models of vertical multistage pumps on the same dedicated machine, demonstrating strong equipment compatibility. Through the cooperation of the electric translation module and the servo lifting module, stable and uniform pressing force can be provided to the vertical multistage pumps, improving the assembly quality while saving the physical labor of operators.

[0019] 3. The flipping mechanism of the crate loading machine of the present invention drives the L-shaped bracket to flip through the flipping cylinder, switching the working positions of the crate positioning and conveying mechanism and the water pump moving and clamping mechanism. When the crate positioning and conveying mechanism is in a horizontal state, it is convenient to carry out the input and output of crates. When the water pump moving and clamping mechanism is in a horizontal state, it is convenient to clamp the water pump and also more convenient to transport the water pump into the crate. By switching the crate positioning and conveying mechanism and the water pump moving and clamping mechanism to work together, different types of water pumps are automatically loaded into the crate, resulting in high packing efficiency and reduced labor intensity for workers.

[0020] 4. The beneficial effect of the water pump packaging line of the present invention is that when the water pump needs to be wrapped with film, the first transition section, the transition conveyor chain, and the transition conveyor support move the wooden pallet carrying the water pump toward the carrying conveyor chain. As the end of the wooden pallet is continuously pushed forward in the first transition section, the front end of the wooden pallet overlaps the transition conveyor chain and moves toward the carrying conveyor chain. After entering the wooden pallet product wrapping machine, the wooden pallet is suspended below, allowing for film wrapping. When the front end of the wooden pallet enters the carrying conveyor chain, the end of the wooden pallet just reaches the end of the first transition section, at which point the film wrapping work is completed. Afterwards, the transition conveyor support moves in the opposite direction with the transition conveyor chain, extending into the wooden pallet product wrapping machine to support the end of the wooden pallet, preventing… The wooden pallet falls from the conveyor line and, together with the carrying conveyor chain, drags the wrapped wooden pallet onto the carrying conveyor chain until it reaches the end, where it is then removed from the line. When the water pump loads the wooden box, it enters the wooden pallet product wrapping machine without being wrapped with film. Since the input end of the transition conveyor chain is adjacent to the end of the first transition section, the wooden box is directly transferred to the carrying conveyor chain by the first transition section conveyor chain. Subsequently, it is pulled off the line by the carrying conveyor chain. This invention realizes the co-line packaging of wrapped and non-wrapped products, with good production line compatibility, low production line downtime, and no reduction in the packaging line conveying speed during the wrapping and non-wrapping production processes, thus ensuring the production efficiency of the packaging line.

[0048] Example 1

[0049] like Figure 1 As shown, this invention discloses a vertical multistage pump production line, which covers five major process modules. The first process module is the assembly stage, in which a special assembly machine 1 assembles the components of the vertical multistage pump 707 into a complete water pump. The second process module is the performance testing stage, in which a special testing machine performs performance tests on each assembled vertical multistage pump. The qualified product is the sole criterion for successful assembly. The third process module—rework stage—is configured in this stage. After the performance test, there may be unqualified products of the vertical multistage pump. The rework machine 3 needs to repair the unqualified products. After the repair, the performance test is carried out again until the test result is qualified before it can flow to the fourth process module—post-processing stage. After the performance test, the vertical multistage pump must be removed from the pump chamber and pump surface by the post-processing machine 5 in the post-processing stage. It must also be sealed in a bag or have a nameplate affixed until the vertical multistage pump 707 meets the requirements for entering the box. The vertical multistage pump 707, which meets the requirements for boxing, is transferred to the boxing machine 7 and the water pump packaging line 8. After the boxing and packaging operation is completed, the complete production process is achieved.

[0050] The specific arrangement is as follows: Within the process setting range, several tooling plates 112 are set on the conveyor line 3 for conveying the vertical multistage pump 707. Several vertical multistage pump assembly machines 1 are set on the left and right sides of the conveyor line, and the number is determined according to the production efficiency. Several reversing lifting and moving machines are set on the conveyor line 3 to transport the vertical multistage pump 707 on the conveyor line to the assembly machine 1. This embodiment is one arrangement reference. After assembly, several testing machines 2 and testing systems are set on one side of the conveyor line 3. In order to provide better noise testing environment conditions, the testing machines are arranged in soundproof rooms, and the testing operations are carried out in the rooms. One assembly machine is equipped with one soundproof room. The number of testing machines is determined according to the production efficiency. This embodiment is one arrangement reference. After testing, the vertical multistage pump 707 will have two results: "qualified" and "unqualified". "Qualified" products will be sent to the post-processing machine 5 for post-processing. The post-processing machine 5 is located on one side of the conveyor line 3, and the number of post-processing machines 5 depends on production efficiency; this example is one possible arrangement. "Unqualified" products will not be sent to the post-processing machine 5, but instead to the rework machine 4. After the "unqualified" pump is repaired, it will re-enter the testing machine 2 for performance testing to determine its qualification status again. Only pumps that pass the rework process can be sent to the post-processing machine 5. After post-processing, the vertical multistage pump 707 is sent to the off-line station, where it and the tooling plate 112 are separated from the conveyor line 3. Empty tooling plate 112 enters the water suction machine 6, which removes residual water from the empty tooling plate 112. After the residual water is removed, the waterless tooling plate 112 returns to the beginning of the lower conveyor line. The beginning of the conveyor line 3 is equipped with an end lift, which lifts the tooling plate 112 back to the previous conveyor line, starting a new cycle. To ensure production continuity, the conveyor line is equipped with multiple tooling plates. The vertical multistage pump 707 of the lower conveyor line 3 is transferred to the boxing machine 7. After being boxed and packaged by the boxing machine 7 and the water pump packaging line 8, it finally meets the conditions for shipment.

[0051] like Figure 2-5 As shown, the assembly machine 1 of the present invention includes: a frame box 102, a lifting device 101 is provided at the front of the frame box 102, an electric roller bracket 109 is fixed at the top edge of the lifting device 101, an electric roller 110 is provided at one end of the electric roller bracket 109, a tool basket 111 is provided at the other end, and a limit stop 113 is also provided on the side of the tool basket 111 near the electric roller bracket 109.

[0052] In a preferred embodiment, the rack housing 102 has a drawer 114 and a control panel 115 on its side. A back plate 103 is fixed to one end of the rack housing 102 near the control panel 115. A guide plate 104 is fixed to the top of the back plate 103, and a guide rail 105 is provided at the bottom of the guide plate 104. An electric translation module 106 is mounted on the rack housing 102, and a servo lifting module 107 is mounted on the electric translation module 106. The top of the servo lifting module 107 is slidably disposed in the guide rail 105, and a planar rotary pressure plate 108 is provided at the lifting end of the servo lifting module 107. Driven by the electric translation module 106, the servo lifting module 107 slides along the guide rail 105, which improves the sliding stability of the servo lifting module 107. Operating lights 116 are provided at the bottom of the guide plate 104 on both sides of the guide rail 105, and running indicator lights 117 and hooks 121 are provided at the front end of the guide plate 104. A cabinet door 118 is provided at the end of the rack housing 102 near the back panel 103 for easy inspection and maintenance of the equipment. Several power interfaces 119 and air supply interfaces 120 are provided on the back panel 103.

[0053] The working principle of the assembly machine 1 is as follows: In the initial state, the lifting end of the lifting device 101 is raised to the same height as the conveyor line 3, so that the tooling plate 112 can be transported to the limit stop 113 through the electric roller 110 for accurate positioning. Initially, the electric translation module 106 is moved to the tail end, and the servo lifting module 107 is raised to the high position (the above preparations are to keep the flat rotary pressure plate 108 away from the assembly workbench so as not to affect the hoisting work of the vertical multistage pump 707 assembly). The operator assembles the components of the vertical multistage pump 707 step by step from bottom to top. During the assembly process, the height of the vertical multistage pump 707 continuously increases. At this time, the lifting end of the lifting device 101 descends to a suitable height, so that the operator does not need to lift their feet or bend over to assemble. When the assembly reaches a certain designated stage, the electric translation module 106 moves towards the operator and into position. Then, the servo lifting module 107 drives the planar rotary pressure plate 108 to descend until the planar rotary pressure plate 108 can firmly press the upper plane of the pump assembly and apply pressure to the assembly. At this time, the geometric center of the planar rotary pressure plate 108 coincides with the geometric center of the assembly. The downward pressure provided by the planar rotary pressure plate 108 is pre-set and provides accurate downward pressure under servo control. It can provide good pressing force without damaging the assembly. After pressing, the assembly can be manually rotated to continue the assembly. After the press-fit assembly is completed, the planar rotary press plate 108 returns to its initial position under the drive of the servo lifting module 107 and the electric translation module 106. After the vertical multistage pump 707 is assembled in the special machine, the lifting end of the lifting device 101 rises to the same height as the conveyor line 3, and the electric roller 110 reverses, outputting the assembled vertical multistage pump 707 from the special machine to the conveyor line 3, completing the assembly of one water pump product, and waiting for the next tooling plate 112 to enter, and starting the assembly of the next product.

[0054] Example 2

[0055] like Figure 6-18 As shown, the difference between this embodiment and the previous embodiment is that this embodiment also discloses a box-loading machine 7. The box-loading machine 7 is set on one side of the 3 conveyor line and is used for boxing the vertical multistage pump 707. The box-loading machine 7 includes a frame 701, a tilting mechanism 702, a wooden box positioning and conveying mechanism 703, and a water pump moving and clamping mechanism 704. The tilting mechanism 702, the wooden box positioning and conveying mechanism 703, and the water pump moving and clamping mechanism 704 are all controlled by a PLC.

[0056] The flipping mechanism 702 includes a flipping cylinder 721 and an L-shaped bracket 722. A flipping bearing seat 711 is provided on the frame 701. The L-shaped bracket 722 is hinged to the flipping bearing seat 711 via a flipping shaft. The fixed end of the flipping cylinder 721 is hinged to the frame 701 via a hinge shaft. The free end of the flipping cylinder 721 is hinged to the L-shaped bracket 722. In this embodiment, an extension plate is provided at the outer corner of the L-shaped bracket 722. The L-shaped bracket 722 is hinged to the free end of the flipping cylinder 721 via the extension plate. The flipping cylinder 721 is used to drive the L-shaped bracket 722 to flip around the flipping bearing seat 711. That is, the extension and retraction of the free end of the flipping cylinder 721 can drive the L-shaped bracket 722 to flip.

[0057] The wooden box positioning and conveying mechanism 703 is connected to the L-shaped bracket 722. The wooden box positioning and conveying mechanism 703 is used for clamping, positioning or conveying wooden boxes. The water pump moving clamping mechanism 704 is connected to the L-shaped bracket 722. The water pump moving clamping mechanism 704 is used for clamping and translating the water pump.

[0058] The wooden crate positioning and conveying mechanism 703 includes a wooden crate clamping mechanism 731, a support chain drive assembly 732, and a support chain drive motor 733. The support chain drive assembly 732 is rotatably connected to the first inner sidewall 7221 of the L-shaped bracket 722, and the support chain drive motor 733 is fixedly connected to the first inner sidewall 7221. The support chain drive motor 733 is used to drive the support chain drive assembly 732 to move, and the wooden crate clamping mechanism 731 is fixedly connected to the L-shaped bracket 722.

[0059] Furthermore, a load-bearing drive shaft 734 and a tensioning shaft are rotatably connected to the first inner sidewall 7221. The two ends of the load-bearing chain drive assembly 732 are respectively connected to the load-bearing drive shaft 734 and the tensioning shaft. The load-bearing chain drive motor 733 is connected to the load-bearing drive shaft 734 through a transmission connection. The load-bearing chain drive motor 733 and the load-bearing drive shaft 734 are connected to a matching bevel gear, that is, both the load-bearing drive shaft 734 and the load-bearing chain drive motor 733 are connected to a bevel gear, and the two bevel gears mesh for transmission. In this embodiment, the middle section of the load-bearing chain drive assembly 732 is directly supported by a profile, which strengthens the load-bearing performance.

[0063] When the wooden box clamping mechanism 731 is working, the PLC controls the wooden box clamping cylinder to work.

The other first synchronous rack 73132 slides along with it through the transmission action of the first synchronous gear 73133. The two first synchronous racks 73132 move towards each other or away from each other at the same time, realizing the adjustment of the clamping distance between the two first clamping claws 73131, which can clamp wooden boxes of different sizes.

[0064] The water pump moving clamping mechanism 704 includes a translation bracket 741, a water pump translation mechanism 742, a water pump lifting mechanism 743, and a water pump synchronous clamping mechanism 744.

[0065] The water pump translation mechanism 742 includes a water pump translation control motor 7421 and a first lead screw 7422. The water pump translation control motor 7421 is fixedly connected to the second inner sidewall 7222. A first rotating seat 7423 is provided on the second inner sidewall 7222.

The water pump translation control motor 7421 is controlled by a PLC to run and drive the first lead screw 7422 to rotate. The translation bracket 741, which is threadedly connected to the first lead screw 7422, can move horizontally along the second guide rail 745.

[0066] The water pump lifting mechanism 743 includes a lifting control servo motor 7431 and a second lead screw 7432. The lifting control servo motor 7431 is fixedly connected to the translation bracket 741. A second rotating seat 7433 is provided on one side of the translation bracket 741.

The water pump synchronous clamping mechanism 744 is threadedly connected to the second lead screw 7432. In this embodiment, the end of the second lead screw 7432 is rotatably connected using a ball bearing. The lifting control servo motor 7431 is controlled by a PLC to run and drive the second lead screw 7432 to rotate. The water pump synchronous clamping mechanism 744, which is threadedly connected to the second lead screw 7432, slides along the third guide rail 746.

[0067] The water pump synchronous clamping mechanism 744 includes a side slide plate 7441, a water pump clamping cylinder 7442, two second clamping claws 7443, two second synchronous racks 7444, and a second synchronous gear 7445. The side slide plate 7441 is slidably connected to a third guide rail 746. A fourth guide rail 7446 is provided on the side slide plate 7441. The two second clamping claws 7443 are slidably connected to the fourth guide rail 7446.

[0068] When the water pump synchronous clamping mechanism 744 is working, the PLC controls the water pump clamping cylinder 7442 to work. The power output end of the water pump clamping cylinder 7442 drives the second clamping claw 7443 and a second synchronous rack 7444 connected to it to slide. The other second synchronous rack 7444 slides along with it through the transmission action of the second synchronous gear 7445. The two second synchronous racks 7444 move towards or away from each other at the same time, realizing the adjustment of the clamping distance between the two second clamping claws 7443, which can clamp water pumps of different sizes.

[0069] As an optimization, a water pump translation support plate 705 is fixedly connected to the bottom end of the translation support 741 near the wooden box positioning and conveying mechanism 703, which facilitates the dragging of the water pump; a wooden box end limiting platform 708 is provided on the second inner side wall 7222, which can limit the end of the wooden box 706.

[0070] The present invention discloses a special machine for box filling. When it is working, such as... Figure 13-18As shown, in the initial state, the free end of the tilting cylinder 721 is extended into position, the wooden box positioning and conveying mechanism 703 is in a horizontal state, the water pump moving clamping mechanism 704 is in a high position, and the first clamping claw 73131 of the wooden box synchronous clamping mechanism 7313 and the second clamping claw 7443 of the water pump synchronous clamping mechanism 744 are both in an open state. The support chain drive motor 733 drives the support chain transmission group 732 and drives the wooden box 706 to move. The device is in the wooden box input state. After the wooden box 706 is input into position, the free end of the tilting cylinder 721 is controlled to retract, and the L-shaped frame 22 is rotated 90° so that the water pump moving clamping mechanism 704 is in a horizontal state, moving towards the water pump synchronous clamping mechanism. A vertical multistage pump 707 is placed inside the wooden box 744 and clamped. Then, the pump lifting mechanism 743 adjusts the clamping height of the vertical multistage pump 707 and controls the pump translation mechanism 742 to drive the vertical multistage pump 707 to be completely sent into the wooden box 706. After being sent to the appropriate position, the pump synchronous clamping mechanism 744 no longer clamps the vertical multistage pump 707 and controls the L-shaped bracket to rotate 90°, so that the wooden box positioning and conveying mechanism 703 is in a horizontal state again. Finally, the support chain drive motor 733 drives the support chain transmission group 732 and drives the wooden box 706 to move, sending out the wooden box 706 containing the vertical multistage pump 707, completing one packing operation of the vertical multistage pump 707.

[0071] Example 3

[0072] like Figure 19-24 As shown, the difference between this embodiment and Embodiment 2 is that this embodiment also discloses a water pump packaging line 8, including a first transition section 820, a wooden pallet product winding machine 830, and a carrying transition conveyor 840. The first transition section 820 is located at the output end of the box-entry machine 7 (the first transition section uses a chain to drive product movement, a conventional technical means, which will not be described in detail here). The wooden pallet product winding machine 830 is located between the first transition section 820 and the carrying transition conveyor 840. The carrying transition conveyor 840 includes a first frame 841, a carrying conveyor chain 842, and a transition conveying device 843. The carrying conveyor chain 842 is rotatably mounted on the first frame 841. 1. The conveyor chain 842 rotates on the first frame 841 by a motor drive, a conventional technique, which will not be elaborated on here. The transition conveyor device 843 includes a transition conveyor chain 8431 and a transition conveyor support 8432. The transition conveyor chain 8431 is rotatably connected to the transition conveyor support 8432. The rotation of the transition conveyor chain 8431 on the transition conveyor support 8432 is a non-powered structure. The first frame 841 is provided with a guide rail 8411. The transition conveyor support 8432 slides on the guide rail 8411. The transition conveyor support 8432, carrying the transition conveyor chain 8431, can extend into the wooden pallet product winding machine 830.

[0073] Preferably, the transition conveying device 843 further includes a horizontal conveying motor 8433 and a ball screw 8434. The horizontal conveying motor 8433 is mounted on the frame, and the ball screw 8434 is mounted on the output end of the horizontal conveying motor 8433. The ball screw 8434 is threadedly connected to the bottom end of the transition conveying bracket 8432.

[0074] When the vertical multistage pump 707 is packaged in a wooden box 706, after the wooden box 706 is loaded by the box-loading machine 7, it enters the first transition section 820 and is driven to continue moving forward. When the front end of the wooden box 706 is about to reach the end of the first transition section 820, since the input end of the transition conveyor chain 8431 at its initial position is next to the end of the first transition section 820, the wooden box 706 is directly transferred to the carrying conveyor chain 842 by the conveyor chain 8431 under the push of the conveyor chain of the first transition section 820. Then, the front end of the wooden box 706 is pulled by the carrying conveyor chain 842 and completely enters the carrying conveyor chain 842, and is unloaded at the end of the water pump packaging line 8. During this process, it passes through the wooden pallet product wrapping machine 830, which does not wrap the wooden box 706 with film.

[0075] When the vertical multistage pump 707 uses the wooden pallet 860, both the vertical multistage pump 707 and the wooden pallet 860 need to be wrapped with film. After the wooden pallet 860 is packed in the box by the boxing machine 7, it enters the first transition section 820 and is driven to continue moving forward. When the front end of the wooden pallet 860 is about to reach the end of the first transition section 820, because the input end of the transition conveyor chain 8431 at its initial position is adjacent to the end of the first transition section 820, the wooden pallet 860, driven by the conveyor chain of the first transition section 820, moves forward. The front end of the wooden pallet 860 enters the transition conveyor chain 8431. The horizontal conveyor motor 8433 drives the horizontal conveyor support 8432 to move horizontally, thereby enabling the transition conveyor chain 8431 to drag the front end of the wooden pallet 860 (the transition conveyor chain 8431 is a non-powered structure, and during this process, the transition conveyor chain 8431 only supports the front end of the wooden pallet 860). Under the driving force of the first transition section 820, the wooden pallet 860 moves towards the carrying conveyor chain 842. During the process, the horizontal movement speed of the transition conveyor chain 8431 is the same as the movement speed of the wooden tray 860; during the process, the end of the wooden tray 860 is continuously pushed forward in the first transition section 820, and the front end of the wooden tray 860 overlaps on the transition conveyor chain. After entering the wooden tray product winding machine 830, the wooden tray is suspended below and film winding can be performed. When the front end of the wooden tray 860 enters the carrying conveyor chain 842, the end of the wooden tray 860 just reaches the end of the first transition section 820, at which point the film winding work ends; horizontal The conveyor motor 8433 drives the ball screw 8434 to rotate in the opposite direction. The transition conveyor chain 8431 moves towards the first transition section 820 to receive the end of the wooden pallet 860. When the front end of the wooden pallet 860 is pulled by the carrying conveyor chain 842, the end of the wooden pallet 860 enters the transition conveyor chain 8431. The front end of the wooden pallet 860 continues to move forward under the pull of the carrying conveyor chain 842 until the wooden pallet 860 is completely entered into the carrying conveyor chain 842, until the wooden pallet 860 is transferred to the end of the line.

[0076] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
