Description

Technical Field

[0001] This application relates to the field of parts transportation, and in particular to a gravity-driven ramp-type automated parts transfer device. Background Technology

[0002] In industrial production, the transfer of parts is crucial, as its efficiency and stability directly impact the smooth operation of the entire production process, as well as product quality and output. With the continuous development of the manufacturing industry, the requirements for parts transfer are becoming increasingly stringent, demanding not only efficient transportation but also reduced labor costs and increased automation.

[0003] In traditional parts handling, manual labor or forklift transportation are commonly used. Manual labor is a basic method where workers move parts from one location to another by hand. While flexible, it is labor-intensive, inefficient, and prone to human error. Forklift transportation uses forklifts to move parts short distances and can carry a certain weight, but it requires specialized operators and is less flexible in confined spaces.

[0004] However, these traditional transportation methods have significant drawbacks. Manual handling and forklift transportation require a large workforce, increasing production costs. Moreover, workers are prone to fatigue during long hours, leading to decreased efficiency and safety accidents. Therefore, providing a device that facilitates the transport of parts is an urgent problem to be solved. Summary of the Invention

[0005] To facilitate the transport of parts, this application provides a gravity-driven ramp-type automatic parts transfer device.

[0006] The gravity-driven ramp-type automatic parts transfer device provided in this application adopts the following technical solution: A gravity-driven ramp-type automatic parts transfer device includes two uprights, two track assemblies, and a transport assembly connected to the track assemblies; The two uprights are spaced apart in a first direction, one of which is the front upright and the other is the rear upright; The two track components are distributed at a distance in the vertical direction, one being an upper track component and the other being a lower track component located below the upper track component; the track component includes: A truss, with each end of the truss fixedly connected to one of the uprights; the truss in the upper track assembly is the upper truss, and the truss in the lower track assembly is the lower truss; the upper truss is inclined downward from the front upright to the rear upright, and the lower truss is inclined downward from the rear upright to the front upright; The transport component includes: The main tray is attached to the upper truss, and the main tray is slidably connected to the upper truss along the inclined direction of the upper truss; An auxiliary tray is attached to the lower truss, and the auxiliary tray is slidably connected to the lower truss along the inclined direction of the lower truss; In addition, a rope is fixedly connected to the main tray at one end, the rope passes around the end of the upper truss near the front upright and then folds over the end of the lower truss near the rear upright, and is fixedly connected to the auxiliary tray; When the main pallet is positioned at the front upright under the traction of the rope, the auxiliary pallet is also positioned at the front upright.

[0007] By adopting the above technical solution, when transferring parts, the parts are placed on the main pallet located at the front upright. Since the upper truss is inclined downwards from the front upright to the rear upright, the main pallet slides downwards along the inclined direction of the upper truss under the influence of gravity. Simultaneously, one end of a rope is fixed to the main pallet, passes around the upper truss near the front upright, folds over at the lower truss near the rear upright, and is fixedly connected to an auxiliary pallet. During the main pallet's descent, the rope pulls the auxiliary pallet upwards along the lower truss, bringing it closer to the rear upright. When the main pallet reaches the rear upright, the parts are removed, and the auxiliary pallet slides downwards along the inclined direction of the lower truss under its own gravity. This, in turn, pulls the main pallet upwards along the upper truss back to its initial position at the front upright via the rope. This cycle achieves automatic transfer of parts, reducing manpower and improving transfer efficiency.

[0008] Optionally, a counterweight is placed on the auxiliary tray.

[0009] By adopting the above technical solution, a counterweight is placed on the auxiliary pallet, which increases the weight of the auxiliary pallet and ensures that the auxiliary pallet can smoothly drive the main pallet back to its initial position when the main pallet is unloaded. The weight of the counterweight can also be adjusted according to actual needs to adapt to the transfer of parts of different weights.

[0010] Optionally, it may also include a guide component, the guide component comprising: The front guide wheel, which is rotatably connected to the upper truss, is located at the end of the upper truss away from the rear support and above the upper truss; The front pulley, which is rotatably connected to the upper truss, is located at the end of the upper truss away from the rear support and below the upper truss; The rear guide wheel, which is rotatably connected to the upper truss, is located at the end of the upper truss away from the front upright and below the upper truss; Additionally, the rear pulley, which is rotatably connected to the lower truss, is located at the end of the lower truss away from the front upright, and in the vertical direction, it is located between the lower truss and the rear guide wheel; One end of the rope is fixedly connected to the main tray, and the other end is sequentially wrapped around the front guide wheel, the front pulley, the rear guide wheel and the rear pulley before being fixedly connected to the auxiliary tray.

[0011] By adopting the above technical solution, the guide assembly is equipped with a front guide wheel, a front pulley, a rear guide wheel, and a rear pulley, so that the rope is wound around these components. This ensures the stability of the rope's movement trajectory, avoids friction or entanglement between the rope and the truss, and improves the reliability of the device.

[0012] Optionally, the track assembly also includes auxiliary rollers; the truss is provided with multiple rows of auxiliary rollers, the multiple rows of auxiliary rollers are arranged at intervals in the second direction, and the multiple auxiliary rollers in each row are arranged sequentially in the inclination direction of the truss; the rotation axis of the auxiliary rollers is parallel to the second direction; the main tray and the auxiliary tray are both attached to the auxiliary rollers.

[0013] By adopting the above technical solution, multiple rows of auxiliary rollers are set on the truss, and the main pallet and auxiliary pallet overlap on the auxiliary rollers, which reduces the friction between the main pallet and auxiliary pallet and the truss, improves the smoothness of the sliding of the main pallet and auxiliary pallet on the upper and lower trusses, and thus improves the transfer efficiency of parts.

[0014] Optionally, it also includes a thrust assembly located at one end of the lower truss near the rear support frame, the thrust assembly comprising: A mounting base fixedly connected to the lower truss; A push rod is slidably connected to the mounting base along its own length direction, and the push rod is parallel to the inclination direction of the lower truss; Additionally, a tension spring is fixedly connected at one end to the push rod and at the other end to the mounting base, the tension direction of the tension spring being parallel to the push rod; When the auxiliary tray contacts the push rod, and the auxiliary tray moves from the front upright to the rear upright, the tension spring stretches and stores the force that drives the push rod to move from the rear upright to the front upright.

[0015] By adopting the above technical solution, when the auxiliary pallet moves from the front upright to the rear upright and contacts the push rod, it pushes the push rod to slide along its own length on the mounting base, causing the tension spring to stretch. At this time, the tension spring stores the force that drives the push rod to move from the rear upright to the front upright. When the auxiliary pallet returns to the front upright, the tension spring releases the stored force, pushing the push rod to move, thereby providing additional thrust for the auxiliary pallet.

[0016] Optionally, a stop bar is fixedly connected to the top of the rear support frame, and the main pallet contacts the stop bar when it slides along the upper truss to its lowest point.

[0017] By adopting the above technical solution, the baffle can play a buffering role when the main pallet slides along the upper truss to the lowest point and contacts it, avoiding rigid collision between the main pallet and the rear upright, and protecting the main pallet and components.

[0018] Optionally, the top of the main pallet is provided with a barrier assembly, the barrier assembly comprising: A main baffle is located at one end of the main tray near the baffle strip and is slidably connected to the main tray along a second direction.

[0019] By adopting the above technical solution, the main baffle can prevent parts from falling off the end of the main pallet near the baffle bar during transportation.

[0020] Optionally, it also includes a feeding assembly, the feeding assembly comprising: A support frame is located on the side of the rear upright and is fixedly connected to the rear upright; A sliding seat, which is slidably connected to the support frame along a second direction; A linear drive unit is connected between the sliding seat and the support frame to drive the sliding seat to move in a second direction; A pneumatic gripper fixedly connected to the sliding seat; In addition, a clamping block is fixedly connected to each of the two output ends of the pneumatic gripper, and a clamping area is formed between the two clamping blocks; when the main tray abuts against the stop bar, the pneumatic gripper can move with the sliding seat until the main stop plate is located in the clamping area.

[0021] By adopting the above technical solution, when the main pallet reaches the side of the rear upright, the unloading component can drive the sliding seat to move through the linear drive component, so that the pneumatic gripper can drive the clamping block to clamp the main baffle and realize the dropping of the parts.

[0022] Optionally, it also includes a receiving assembly, the receiving assembly comprising: A receiving box with an open top is located on the side of the rear upright away from the front upright; A lifting plate located inside the receiving box, the lifting plate being slidably connected to the receiving box in a vertical direction; In addition, a compression spring is located below the lifting plate, one end of which is fixedly connected to the bottom of the receiving box, and the other end is fixedly connected to the lifting plate.

[0023] By adopting the above technical solution, the unloading assembly can remove the main baffle on the main pallet, allowing the parts to fall off; the receiving box of the receiving assembly can collect the parts that fall off the main pallet, the lifting plate can slide vertically, and the compression spring can dampen the falling parts, reducing damage to the parts.

[0024] Optionally, the lifting plate is inclined downward in the direction from the front upright to the rear upright.

[0025] By adopting the above technical solution, the lifting plate is tilted downwards to facilitate the collection of parts at the bottom of the lifting plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By adopting a gravity-driven ramp structure and rope traction, automatic transfer of parts is achieved, reducing labor costs and increasing the degree of automation; The auxiliary rollers reduce friction between the main and auxiliary pallets and the truss, improving transfer efficiency; The enclosure assembly prevents parts from falling off the main pallet during transport, ensuring transport stability.

[0029] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail. For ease of description, this application introduces directional terms such as "first direction" and "second direction". The specific directional terms used, such as "first direction" and "second direction", can be referred to in the attached drawings, where X represents the first direction and Y represents the second direction. The first direction and the second direction are perpendicular to each other and both are perpendicular to the vertical direction.

[0030] This application discloses a gravity-driven, ramp-type automatic parts transfer device. (Refer to...) Figure 1 The gravity-driven ramp-type automatic component transfer device includes two uprights 1, two track assemblies 2, and a transport assembly 3 connected to the track assemblies 2; wherein, the two uprights 1 are spaced apart in a first direction, one of which is the front upright 1a and the other is the rear upright 1b; the uprights 1 are frame structures perpendicular to the first direction, and can be welded from multiple square steel or angle steel structures to provide reliable support for the entire device.

[0031] Reference Figure 1 and Figure 2 Two track components 2 are distributed at intervals in the vertical direction, one of which is the upper track component 2a, and the other is the lower track component 2b located below the upper track component 2a; The track assembly 2 includes a truss 21, with each end of the truss 21 fixedly connected to a support frame 1; the truss 21 in the upper track assembly 2a is the upper truss 21a, and the truss 21 in the lower track assembly 2b is the lower truss 21b; the upper truss 21a is inclined downward from the front support frame 1a to the rear support frame 1b, and the lower truss 21b is inclined downward from the rear support frame 1b to the rear front support frame 1a; and the two trusses 21 are symmetrically arranged about a horizontally arranged reference plane, and in the vertical direction, the reference plane is located between the two trusses 21.

[0032] The track assembly 2 also includes auxiliary rollers 22. The truss 21 is provided with multiple rows of auxiliary rollers 22, which are spaced apart in the second direction. Specifically, in this embodiment, each truss 21 is provided with two rows of auxiliary rollers 22, and each of the two sides of the truss 21 is provided with a corresponding row of auxiliary rollers 22. The multiple auxiliary rollers 22 in each row are arranged sequentially in the inclined direction of the truss 21. The auxiliary rollers 22 are rotatably connected to the truss 21 around their own central axis, and the rotation axis of the auxiliary rollers 22 is parallel to the second direction.

[0033] Reference Figure 1 The transport component 3 includes a main pallet 31, an auxiliary pallet 32, and a rope 33. The main pallet 31 overlaps the upper truss 21a and slides back and forth along the inclined direction of the upper truss 21a. The auxiliary pallet 32 ​​overlaps the lower truss 21b and slides back and forth along the inclined direction of the lower truss 21b. Specifically, both the main pallet 31 and the auxiliary pallet 32 ​​overlap on auxiliary rollers 22 to improve the smoothness of their sliding on the upper truss 21a and the lower truss 21b. The auxiliary rollers 22 further reduce the friction between the main pallet 31 and the auxiliary pallet 32 ​​and the truss 21, thereby improving the transfer efficiency. A stop bar 11 is fixedly connected to the top of the rear upright 1b. When the main pallet 31 slides along the upper truss 21a to its lowest point, it contacts the stop bar 11. The stop bar 11 can be made of rubber to provide cushioning and prevent the main pallet 31 from having a rigid collision with the rear upright 1b, thus protecting the main pallet 31 and its components.

[0034] Rope 33 can be made of steel wire rope, which has high strength and wear resistance; one end of rope 33 is fixed to the main pallet 31, and after passing around the upper truss 21a near the front upright 1a, rope 33 is folded over at the lower truss 21b near the rear upright 1b and fixedly connected to the auxiliary pallet 32; under the traction of rope 33, when the main pallet 31 approaches the front upright 1a, the auxiliary pallet 32 ​​approaches the rear upright 1b; the connection between rope 33 and the main pallet 31 and the auxiliary pallet 32 ​​can be fixed by buckles or bolts; When the main pallet 31 is at the front upright 1a under the traction of the rope 33, the auxiliary pallet 32 ​​is also at the front upright 1a; when the main pallet 31 is at the rear upright 1b, the auxiliary pallet 32 ​​is also at the rear upright 1b. In other words, when the main pallet 31 is located on the side of the front upright 1a and a component is placed on the main pallet 31, due to the inclination of the upper truss 21a, the main pallet 31 slides downward under the action of gravity, and the auxiliary pallet 32 ​​is driven upward by the rope 33 to move closer to the rear upright 1b; when the main pallet 31 reaches the lower end of the lower truss 21b, the component is removed, and the gravity on the auxiliary pallet 32 ​​causes it to slide downward, and then the main pallet 31 is driven upward by the rope 33 to return to the loading position of the component, thus realizing the automatic transfer of the component.

[0035] Reference Figure 1 In addition, a counterweight 34 is placed on the auxiliary pallet 32. The counterweight 34 can be a metal block, such as an iron block. By increasing the weight of the auxiliary pallet 32, it ensures that when the main pallet 31 is unloaded, the auxiliary pallet 32 ​​can smoothly drive the main pallet 31 back to its initial position. In some cases, the weight of the counterweight 34 can also be adjusted according to actual needs to accommodate the transfer of parts of different weights.

[0036] Reference Figure 3 , Figure 4 and Figure 5 To ensure smoother sliding of the rope 33, some embodiments of this application also include a guide assembly 4. The guide assembly 4 includes a front guide wheel 41, a front pulley 42, a rear guide wheel 43 rotatably connected to the upper truss 21a, and a rear pulley 44 rotatably connected to the lower truss 21b. The connection between the front guide wheel 41, the front pulley 42, the rear guide wheel 43, and the rear pulley 44 and the two uprights 1 is as follows: four wheel seats 45 are fixedly connected to the uprights 1, and the front guide wheel 41, the front pulley 42, the rear guide wheel 43, and the rear pulley 44 are each rotatably connected to one wheel seat 45, and the axis of rotation is parallel to the second direction. Specifically, the front guide wheel 41 is located at the end of the upper truss 21a away from the rear upright 1b and above the upper truss 21a; the front pulley 42 is located at the end of the upper truss 21a away from the rear upright 1b and below the upper truss 21a; the rear guide wheel 43 is located at the end of the upper truss 21a away from the front upright 1a and below the upper truss 21a; and the rear pulley 44 is located at the end of the lower truss 21b away from the front upright 1a, and in the vertical direction, it is located between the lower truss 21b and the rear guide wheel 43. One end of rope 33 is fixedly connected to the main tray 31, and the other end is sequentially wound around the front guide wheel 41, the front pulley 42, the rear guide wheel 43, and the rear pulley 44 before being fixedly connected to the auxiliary tray 32. These guide wheels and pulleys can be made of nylon, which is lightweight and wear-resistant. The guide assembly 4 ensures the stability of the movement trajectory of rope 33, avoids friction or entanglement between rope 33 and truss 21, and improves the reliability of the device.

[0037] Reference Figure 5In some embodiments of this application, a thrust assembly 5 is also included at one end of the lower truss 21b near the rear support 1b. The thrust assembly 5 includes a mounting base 51 fixedly connected to the lower truss 21b, a push rod 52 slidably connected to the mounting base 51 along its own length direction, and a tension spring 53 fixedly connected at one end to the push rod 52 and at the other end to the mounting base 51. The push rod 52 is parallel to the inclination direction of the lower truss 21b, and the tension direction of the tension spring 53 is parallel to the push rod 52. When the auxiliary tray 32 contacts the push rod 52, and the auxiliary tray 32 moves from the front support 1a to the rear support 1b, the tension spring 53 is stretched and stores the force that drives the push rod 52 to move from the rear support 1b to the front support 1a. In this embodiment, the tension spring 53 is sleeved on the outer periphery of the push rod 52 to reduce the bending of the tension spring 53; the push assembly 5 can provide additional thrust when the auxiliary tray 32 returns to the side of the forward upright 1a, ensuring that the main tray 31 can return to the initial position smoothly.

[0038] Reference Figure 6 The main pallet 31 is equipped with a barrier assembly 6 on its top. The barrier assembly 6 includes a main baffle 61, which is located at one end of the main pallet 31 near the baffle strip 11 and is slidably connected to the main pallet 31 in a second direction. The upper surface of the main pallet 31 is higher than the baffle strip 11. After the main baffle 61 is removed, the parts placed on the main pallet 31 can slide down along the main pallet 31. Auxiliary baffles 62 are also fixedly connected to other edges on the outer periphery of the main pallet 31. The auxiliary baffles 62 are used to prevent the parts overlapping the main pallet 31 from falling from other directions of the main baffle 61. Therefore, the entire barrier assembly 6 can prevent the parts from falling off the main pallet 31 during the transfer process.

[0039] Reference Figure 7 When the main pallet 31 reaches the side of the rear upright 1b, in order to make the parts on the main baffle 61 fall off, in some embodiments of this application, a feeding assembly 7 is also included. The feeding assembly 7 includes a support frame 71, a sliding seat 72, a linear drive 73, a pneumatic gripper 74, and a clamping block 75. The support frame 71 is located on the side of the rear upright 1b and is fixedly connected to the rear upright 1b. The sliding seat 72 is slidably connected to the support frame 71 in a second direction. The linear drive 73 is connected between the sliding seat 72 and the support frame 71 to drive the sliding seat 72 to move in the second direction. The linear drive 73 can be an electric push rod 52 or a cylinder. Specifically, the cylinder body of the linear drive 73 is fixedly connected to the support frame 71, and the piston rod is fixedly connected to the sliding seat 72. A pneumatic gripper 74 is fixedly connected to a sliding base 72 so that it moves synchronously with the sliding base 72 in the second direction. Each of the two output ends of the pneumatic gripper 74 is fixedly connected to a clamping block 75, forming a clamping area 751 between the two clamping blocks 75. When the main tray 31 abuts against the stop bar 11, the pneumatic gripper 74 can move along the second direction with the sliding base 72 until the main baffle 61 is located in the clamping area 751. The clamping blocks 75 can be made of rubber to increase friction with the main baffle 61 and ensure clamping stability.

[0040] Reference Figure 8 To collect fallen parts, some embodiments of this application further include a receiving assembly 8. The receiving assembly 8 includes a receiving box 81 with an open top, a lifting plate 82 located inside the receiving box 81, and a compression spring 83 located below the lifting plate 82. The receiving box 81 is located on the side of the rear upright 1b away from the front upright 1a, for collecting parts falling from the main tray 31. The lifting plate 82 is slidably connected to the receiving box 81 in a vertical direction, and the sliding is achieved through guide columns or guide rails. No specific limitations are made here, the main purpose is to enable the lifting plate 82 to slide; when the parts fall, the parts fall onto the lifting plate 82 inside the receiving box 81; one end of the compression spring 83 is fixedly connected to the bottom of the receiving box 81, and the other end is fixedly connected to the lifting plate 82. The compression spring 83 extends and retracts in the vertical direction. The compression spring 83 can dampen the parts that fall onto the lifting plate 82 and reduce the damage to the parts; in the direction from the front upright 1a to the rear upright 1b, the lifting plate 82 is set at an angle downward so that the parts can be collected at the bottom of the lifting plate 82.

[0041] Reference Figure 8 In order to prevent parts from falling onto the thrust assembly 5, in some embodiments of this application, an inclined slide plate 9 is fixedly connected to the rear stand 1b. One end of the inclined slide plate 9 is aligned with the upper wall of the baffle 11, and the other end extends downward at an angle to the opening of the receiving box 81. Therefore, after the parts slide off the main tray 31, they can be guided by the inclined slide plate 9 to fall into the receiving box 81.

[0042] The implementation principle of the gravity-driven ramp-type automatic parts transfer device in this application embodiment is as follows: This gravity-driven ramp-type automatic parts transfer device utilizes gravity and rope 33 traction to realize the reciprocating sliding of the main pallet 31 and the auxiliary pallet 32, thereby automatically transferring parts. The upright frame 1 provides support for the device, and the inclined setting of the track assembly 2 allows the main pallet 31 and the auxiliary pallet 32 ​​to slide under the action of gravity, with the rope 33 linking their movements. The setting of auxiliary rollers 22, guide assembly 4, thrust assembly 5, etc., improves the operating efficiency and reliability of the device. The setting of enclosure assembly 6, unloading assembly 7, and receiving assembly 8 further improves the function of the device, realizing the automatic transfer, unloading, and collection of parts.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
