Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more particularly to a parts box conveyor system. Background Technology

[0002] In the current technology, parts need to be placed into part boxes in the parts distribution area within the factory area, and then transported to the corresponding installation station area via slides. After the parts are used, the empty part boxes are returned to the parts distribution area. This requires the installation of two sets of slides with different sliding directions between the parts distribution area and the installation station area, responsible for transporting part boxes with parts and empty part boxes. Each set of slides occupies a certain area, which takes up a considerable amount of factory space. In addition, since the part boxes slide on slides that can only be tilted, sliding from one end of the slide to the other... On one end, the starting position and the destination position correspond one-to-one and cannot be changed. However, there are fewer parts distribution areas and more installation workstations in the factory area. Therefore, it is necessary to set up two sets of slides in each installation workstation area so that the slides can directly lead to each parts distribution area for receiving and transporting parts boxes. Each slide is independent of each other and cannot be shared. The slides used by parts boxes going to different installation workstations and parts boxes transported to the same parts distribution area are all independent of each other, which further increases the space occupied by the slides and results in low space utilization in the factory. Summary of the Invention

[0003] The purpose of this invention is to provide a parts box slide system that solves the problem that existing slides occupy a lot of space in the factory area.

[0004] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a parts box slide system, including a diversion component and a merging component, wherein the diversion component is connected to and perpendicular to the merging component;

[0005] The merging component includes a first support, a first slide rail, and a second slide rail. The first slide rail is higher than the second slide rail. The first slide rail and the second slide rail are installed obliquely on the first support. The lower end of the first slide rail faces the distribution part area, and the higher end of the first slide rail faces the diversion component. The lower end of the second slide rail faces the diversion component, and the higher end of the second slide rail faces the distribution part area.

[0006] The diversion component includes a second bracket, a third slide rail, and a fourth slide rail. The third slide rail is higher than the fourth slide rail. The third and fourth slide rails are installed obliquely on the second bracket. The third slide rail includes two sets, with their lower ends installed opposite each other and forming a gap. The higher end of the first slide rail extends into the gap and is lower than the lower end of the third slide rail. The fourth slide rail includes two sets, with their higher ends abutting each other. The fourth slide rail is installed below the lower end of the second slide rail and is symmetrically installed on both sides of the second slide rail. The higher end of the third slide rail and the lower end of the fourth slide rail face the installation station area.

[0007] Preferably, a lifting component is installed on the side of the first bracket away from the second bracket. The lifting component includes a lifting frame and a slide rail. The slide rail is installed on the first bracket, and the lifting frame is sleeved on the slide rail and slides perpendicularly to the ground. A pulley is installed on the upper side of the first bracket, and a pull rope is wound around the pulley. One end of the pull rope is connected to a weight, and the other end of the pull rope is connected to the lifting frame. The weight of the weight is greater than the weight of the lifting frame, and the weight of the weight is less than the sum of the weight of the lifting frame and the component box. The lifting frame connects with the first slide rail to receive the component box, and the lifting frame connects with the second slide rail to transport the component box.

[0008] Preferably, a limiting rod is installed on the side of the lifting frame near the first bracket; when the lifting frame is connected to the second slide rail, the limiting rod abuts against the parts box on the first slide rail.

[0009] Preferably, a limiting rod is rotatably mounted on the top of the first bracket. The limiting rod is U-shaped, and the connecting part of the middle section of the limiting rod is rotatably mounted on the crossbeam of the first bracket. A first abutting part and a second abutting part are respectively installed at both ends of the limiting rod, and the weight of the first abutting part is greater than that of the second abutting part.

[0010] When the lifting frame rises, the limiting rod abuts against the lower side of the first abutting part, the first abutting part rises, the limiting rod rotates, the second abutting part falls, and the second abutting part contacts the inner wall of the parts box; when the lifting frame falls, the limiting rod rotates, the limiting rod separates from the first abutting part, the first abutting part falls, the second abutting part rises, and the second abutting part separates from the parts box.

[0011] Preferably, a limiting frame is installed on the first bracket, and the limiting rod abuts the first abutting part against the lower side of the limiting frame.

[0012] Preferably, a first guide rail is mounted on the second bracket, the first guide rail is parallel to the second slide rail, and the first guide rail is clamped between the fourth slide rail.

[0013] Preferably, a second guide rail and a third guide rail are also installed on both sides of the first guide rail, and the second guide rail and the third guide rail are parallel to the first guide rail;

[0014] The second guide rail is fixed to the upper side of the first rotating rod. A first balance bar is rotatably mounted on the upper side of the first rotating rod, and a second balance bar is rotatably mounted on the lower side of the first rotating rod. The other end of the first balance bar is connected to the third guide rail. A first crimping part is installed on the other end of the first balance bar. The weight of the first crimping part is greater than that of the third guide rail. The middle section of the second balance bar is rotatably mounted on the second bracket. A second crimping part is installed on the end of the second balance bar away from the second guide rail. The weight of the second crimping part is greater than that of the second guide rail.

[0015] Preferably, rollers are installed on the first slide, the second slide, the third slide, the fourth slide, the first guide rail, the second guide rail, and the third guide rail, and the rollers are in contact with the bottom surface of the parts box.

[0016] Beneficial effects: The high end of the third slide and the low end of the fourth slide within the diversion component face the installation station area. Since there are two sets of both the third and fourth slides, the two sides of the diversion component face different installation station areas. Both installation station areas can transport component boxes along the third slide to the first slide. The component boxes then converge onto the first slide by gravity. Both installation station areas can share the same set of first slides to transport component boxes to the parts distribution area, saving on the number of slides required and thus saving space. When transporting component boxes to the installation station area, they can flow along the second slide to the fourth slides on both sides, where the parts inside the component boxes are placed. At different locations, when the component box slides to the docking point of the two sets of fourth slides, the sides of the component box are suspended in the air, while the middle of the component box is supported by the two sets of fourth slides simultaneously. Due to the different placement positions of the parts inside the component box, the component box can tilt in different directions and then slide onto the fourth slides in different directions. This allows the component box to slide from the same parts distribution area to different installation workstations. Component boxes going to different installation workstations can share the second slide, reducing the space occupied by the slides. At the same time, since the first and second slides are placed overlapping, and the third and fourth slides are placed overlapping, the layout space of the component box slide system is further reduced, making the space utilization rate of the component box slide system in the factory area higher.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0022] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0025] Under current technology, the slides for conveying parts boxes cannot be shared. Each installation station area and parts distribution area will have two sets of slides to transport parts boxes back and forth. The slides are independent of each other and cannot be used interchangeably, which takes up a lot of space, resulting in slides taking up a lot of space in the factory area.

[0026] To solve the above problems, such as Figures 1 to 3 As shown, the present invention provides a parts box slide system, including a diversion component 2 and a merging component 1, wherein the diversion component 2 is connected to and perpendicular to the merging component 1.

[0027] The merging component 1 includes a first support 11, a first slide rail 12, and a second slide rail 13. The first slide rail 12 is higher than the second slide rail 13. The first slide rail 12 and the second slide rail 13 are installed obliquely on the first support 11. The lower end of the first slide rail 12 faces the distribution component area, and the higher end of the first slide rail 12 faces the diversion component 2. The lower end of the second slide rail 13 faces the diversion component 2, and the higher end of the second slide rail 13 faces the distribution component area.

[0028] The diversion component 2 includes a second support 21, a third slide rail 22, and a fourth slide rail 23. The third slide rail 22 is higher than the fourth slide rail 23. The third slide rail 22 and the fourth slide rail 23 are installed obliquely on the second support 21. The third slide rail 22 includes two sets, with the lower ends of the third slide rail 22 installed opposite each other. The third slide rail 22 forms a gap, and the higher end of the first slide rail 12 extends into the gap. The higher end of the first slide rail 12 is lower than the lower end of the third slide rail 22. The fourth slide rail 23 includes two sets, with the higher ends of the fourth slide rail 23 connected to each other. The fourth slide rail 23 is installed on the lower side of the lower end of the second slide rail 13. The fourth slide rail 23 is symmetrically installed on both sides of the second slide rail 13. The higher end of the third slide rail 22 and the lower end of the fourth slide rail 23 face the installation station area.

[0029] Empty parts boxes can be collected along the third slides 22 on both sides and transported to the first slide 12 along the first slide 12 to the parts distribution area. At this time, the parts boxes in the two assembly stations can share the first slide 12, which can save the number of slides and reduce the space occupied by the parts box slide system. After the parts box is filled with parts, it is transported along the second slide 13 to the fourth slide 23. The fourth slide 23 is connected in a figure-eight shape. The middle of the parts box is lifted by the two sets of fourth slides 23, and the sides of the parts box are in a suspended state. At this time, the parts box can be adjusted. The placement of parts within the box can alter the center of gravity of the entire component box. If all parts are placed on the right side, the box will be suspended and tilted to the right into the fourth slide 23 on the right side of the second slide 13. If all parts are placed on the left side, the box will be suspended and tilted to the left into the fourth slide 23 on the left side of the second slide 13. This allows component boxes in the same distribution area to be selectively transported to the installation workstations on both sides, while simultaneously occupying the second slide 13 for transport, saving on the number of slides and reducing the volume occupied by the component box slide system.

[0030] Meanwhile, the first slide rail 12 and the second slide rail 13 on the first support 11 are placed overlapping, and the third slide rail 22 and the fourth slide rail 23 on the second support 21 are placed overlapping, which can further reduce the volume occupied by the parts box slide rail system.

[0031] A lifting component 3 is installed on the side of the first support 11 away from the second support 21. The lifting component 3 includes a lifting frame 31 and a slide rail 32. The slide rail 32 is installed on the first support 11. The lifting frame 31 is sleeved on the slide rail 32 and slides perpendicularly to the ground. A pulley is installed on the upper side of the first support 11. A pull rope is wound around the pulley. One end of the pull rope is connected to a weight 33, and the other end of the pull rope is connected to the lifting frame 31. The weight of the weight 33 is greater than the weight of the lifting frame 31, and the weight of the weight 33 is less than the sum of the weight of the lifting frame 31 and the weight of the parts box. The lifting frame 31 docks with the first slide rail 12 to receive the parts box, and the lifting frame 31 docks with the second slide rail 13 to transport the parts box.

[0032] If the lifting frame 31 is empty, it will be pulled up by the weight 33 via the pull rope on the pulley. The lifting frame 31 will then connect with the first slide rail 12. After receiving the parts box, the weight of the lifting frame 31 will be greater than that of the weight 33, and the lifting frame 31 will slide down to the high end of the second slide rail 13. Then, parts are placed in the parts box, and the position of the parts can be close to the left or right side. Then, the direction of the parts box sliding to the fourth slide rail 23 is selected. After that, the parts box is pushed into the second slide rail 13 and slid towards the fourth slide rail 23. The lifting component 3 can automatically transport the parts box from the first slide rail 12 to the second slide rail 13, saving the operator's physical strength. The operator only needs to place the parts, reducing the workload and making the parts box slide rail system more automated.

[0033] A limit rod 34 is installed on the side of the lifting frame 31 near the first bracket 11. When the lifting frame 31 is connected to the second slide rail 13, the limit rod 34 abuts against the parts box on the first slide rail 12. There are usually multiple sets of control parts boxes arranged on the first slide rail 12. The limit rod 34 can prevent the parts box on the first slide rail 12 from falling off.

[0034] A limiting rod 35 is rotatably mounted on the top of the first bracket 11. The limiting rod 35 is U-shaped. The connecting part of the middle section of the limiting rod 35 is rotatably mounted on the crossbeam of the first bracket 11. A first abutting part 351 and a second abutting part 352 are respectively installed at both ends of the limiting rod 35. The weight of the first abutting part 351 is greater than that of the second abutting part 352. The lifting frame 31 rises, and the limiting rod 34 abuts against the lower side of the first abutment part 351. The first abutment part 351 rises, the limiting rod 35 rotates, and the second abutment part 352 falls. The second abutment part 352 contacts the inner wall of the part box, so that the part box contacted by the second abutment part 352 stops sliding and waits until the front part box is completely entered into the lifting frame 31. The part box abutted by the second abutment part 352 is the part box that is immediately adjacent to the part box that is conveyed to the lifting frame 31. By setting the second abutment part 352, the second set of part boxes can be prevented from sliding into the lifting frame 31 together with the previous set of part boxes, causing jamming, and preventing the lifting frame 31 from being unable to slide down. The second abutment part 352 can keep the number of part boxes entering the lifting frame 31 at one time.

[0035] The part box at the very front of the lowest section of the first slide rail 12 is fully inside the lifting frame 31. The lifting frame 31 descends, and the limiting rod 34 moves down. Due to the weight of the first abutment part 351, the limiting rod 35 rotates, and the second abutment part 352 rises and separates from the part box, allowing the part box on the first slide rail 12 to continue sliding. Then, the limiting rod 34 separates from the first abutment part 351 and descends to the lowest end of the first slide rail 12, preventing the part box on the first slide rail 12 from continuing to slide down. At this time, the lifting frame 31 connects with the second slide rail 13. The component box enters the second slide 13. Then, the lifting frame 31 continues to rise under the pull of the weight 33. The position of the limiting rod 34 is higher than the component box on the first slide 12. The limiting rod 34 continues to abut against the lower side of the first abutment part 351, so that the component box with the lowest position on the first slide 12 continues to enter the lifting frame 31. This cycle repeats, realizing the automatic transportation of the component box from the first slide 12 to the second slide 13. No electrical components are required for transportation. The component box and the lifting frame 31 are moved only by gravity, which is lower in cost and more reliable.

[0036] A limiting frame 36 is installed on the first bracket 11. The limiting rod 34 abuts the first abutting part 351 against the lower side of the limiting frame 36, which can limit the lifting frame 31 pulled by the heavy object 33. The upper stop point of the limiting rod 34 is the position where the lifting frame 31 connects with the first slide rail 12, which makes it easier for the parts box to slide directly from the first slide rail 12 into the lifting frame 31, so that the parts box can run more smoothly under the action of gravity.

[0037] The second bracket 21 is equipped with a first guide rail 4, which is installed at the high end of the fourth slide 23. The first guide rail 4 is parallel to the second slide 13 and is clamped between the fourth slide 23. The part box slides directly along the second slide 13 to the first guide rail 4, making the switching between the part box and the second slide 13 and the first guide rail 4 smoother, avoiding vibration and protecting the internal parts of the part box.

[0038] The first guide rail 4 is also equipped with a second guide rail 5 and a third guide rail 6 on both sides, and the second guide rail 5 and the third guide rail 6 are parallel to the first guide rail 4; the second guide rail 5 is fixed on the upper side of the first rotating rod 7, the first balance rod 8 is rotatably installed on the upper side of the first rotating rod 7, the second balance rod 9 is rotatably installed on the lower side of the first rotating rod 7, the other end of the first balance rod 8 is connected to the third guide rail 6, the other end of the first balance rod 8 is equipped with a first crimping part 81, the weight of the first crimping part 81 is greater than that of the third guide rail 6, the middle section of the second balance rod 9 is rotatably installed on the second bracket 21, the end of the second balance rod 9 away from the second guide rail 5 is equipped with a second crimping part 91, the weight of the second crimping part 91 is greater than that of the second guide rail 5.

[0039] When the parts in the parts box approach the second guide rail 5, the parts box presses against the second guide rail 5. The second guide rail 5 cushions the tilting motion of the parts box, preventing damage to the internal parts. Simultaneously, the weight of the parts box presses against the second balance bar 9. Since the weight of the parts box pressing against the second balance bar 9 is greater than the weight of the second pressing part 91, the second balance bar 9 tilts and the second pressing part 91 tilts upward. The second balance bar 9 rotates around its connection point with the second bracket 21, ultimately causing the second guide rail 5 to move downward under the pressure of the parts box. After the parts box contacts the fourth slide 23 on one side of the second guide rail 5, it slides out along the fourth slide 23. At this time, the weight of the second pressing part 91 is heavier, causing the second guide rail 5 to continue moving upward. When the parts in the parts box approach the second guide rail 21... On one side of the third guide rail 6, the part box will press against the third guide rail 6. The third guide rail 6 can buffer the tilting movement of the part box to avoid damage to the internal parts of the part box. At the same time, the weight of the part box will press against the first balance bar 8. Since the weight of the part box pressing against the first balance bar 8 is greater than the weight of the first pressing part 81, the first balance bar 8 rotates around the connection point with the second balance bar 9, causing the first balance bar 8 to tilt and the first pressing part 81 to tilt upward. Finally, the third guide rail 6 moves downward under the pressure of the part box. The part box contacts the fourth slide 23 on one side of the third guide rail 6 and finally slides out along the fourth slide 23. Then, under the prying of the first pressing part 81, the third guide rail 6 moves upward. Finally, the part box can be selectively transported along the fourth slide 23 on the left and right sides.

[0040] Rollers are installed on the first slide rail 12, the second slide rail 13, the third slide rail 22, the fourth slide rail 23, the first guide rail 4, the second guide rail 5, and the third guide rail 6. The rollers contact the bottom surface of the parts box, reducing the friction between the parts box and the slide rails and guide rails, thus making the parts box transport faster.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
