A linear buffer transport device

Abstract

This utility model relates to the field of linear transportation. Its purpose is to provide a linear buffer transport device that solves the problem of insufficient buffering when the slider is blocked. The device includes a buffer assembly and a transport assembly. A first pull plate is disposed at the end of the front pull rod, and a second pull plate is disposed at the end of the rear pull rod. A first buffer rod is disposed on the second pull plate and has a first end. The first pull plate is movably disposed on the first buffer rod, and a first buffer spring is sleeved on the first buffer rod. The first pull plate continues to compress the first spring, at which point the force on the second pull plate and the rear pull rod gradually decreases, resulting in buffering between the slider and the limiting rod. Simultaneously, the driving component drives the front pull rod to move in the opposite direction. This cycle repeats, ensuring that there is always a buffering effect when the slider is pressed against the limiting rod, thus solving the problem of insufficient buffering when the slider is blocked.

Description

Technical Field

[0001] This utility model relates to the field of linear transportation, and in particular to a linear buffer transport device. Background Technology

[0002] Conventional linear feeding devices will have certain errors in linear motion. These errors are caused by the gaps generated when the universal bearing and driven bearing follow the cam. All the gaps together will cause unstable feeding. The problem to be solved is how to keep the bearing gaps in one direction so that they are close to the cam and reduce feeding errors. Utility Model Content

[0003] The purpose of this invention is to provide a linear buffer transport device that solves the problem of insufficient buffering when the slider is blocked.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a linear buffer transport device, including a buffer assembly and a transport assembly. The buffer assembly includes a front pull rod, a rear pull rod, a first pull plate, a second pull plate, a first buffer rod, and a first buffer spring. The first pull plate is disposed at the end of the front pull rod, the second pull plate is disposed at the end of the rear pull rod, the first buffer rod is disposed on the second pull plate, the first buffer rod has a first end, the first pull plate is movably disposed on the first buffer rod, the first buffer spring is sleeved on the first buffer rod, and the two ends of the first buffer spring respectively abut against the first end and the first pull plate. The front pull rod is used to connect the driving component. The transport component includes a positioning plate, a slider, and a limiting rod. The slider is slidably disposed on the positioning plate, and the limiting rod is disposed on the positioning plate. The limiting rod is located on the slider's movement path. The slider is connected to the rear pull rod and is used to carry items.

[0005] Optionally, the buffer assembly further includes a first universal bearing, which is threadedly connected to the front tie rod, and the first universal bearing is also used to sleeve the drive component.

[0006] Furthermore, the buffer assembly also includes a second universal bearing, which is threadedly connected to the rear pull rod and rotatably connected to the slider.

[0007] Furthermore, the carrier assembly also includes a connecting plate and a connecting rod. The connecting plate is disposed on the slider, and the positioning plate is provided with a sliding hole through which the connecting plate passes. The connecting rod is disposed on the connecting plate and is located below the positioning plate. The second universal bearing is sleeved on the connecting rod.

[0008] Optionally, the carrier assembly further includes a first support, a second support, and a slide rod, wherein the first support and the second support are disposed on the positioning plate, the slide rod is disposed on the first support and the second support, and the slider is slidably disposed on the slide rod.

[0009] Furthermore, the limiting rod is disposed on the first support, and the limiting rod is threadedly connected to the first support.

[0010] Furthermore, the positioning plate is provided with a first limiting groove and a second limiting groove, the first support is disposed in the first limiting groove, and the second support is disposed in the second limiting groove.

[0011] Optionally, the buffer assembly further includes a second buffer rod and a second limiting spring. The second buffer rod is disposed on the second pull plate, and the first pull plate is slidably disposed on the second buffer rod. The second buffer rod has a second end, and the second limiting spring is sleeved on the second buffer rod. The two ends of the second limiting spring abut against the second end and the first pull plate, respectively.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model discloses a linear buffer transport device. When the driving component moves the front pull rod, especially when the first pull plate compresses the first spring, it will drive the second pull plate and the rear pull rod to move. This will cause the slider to move as well. When the slider is pressed against the limit rod, the first pull plate will continue to compress the first spring. At this time, the force on the second pull plate and the rear pull rod gradually decreases, and there is a buffer between the slider and the limit rod. At the same time, the driving component drives the front pull rod to move in the opposite direction. This cycle continues, ensuring that there is a buffering effect when the slider is pressed against the limit rod. Therefore, it solves the problem of lack of buffering when the slider is blocked.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1 and Figure 2 and Figure 3 As shown, a linear buffer transport device includes a buffer assembly 1 and a transport assembly 2. The buffer assembly 1 is moved by a driving component (not shown in the figure), thereby transporting items when the transport assembly 2 moves.

[0019] The buffer assembly 1 includes a front pull rod 11, a rear pull rod 12, a first pull plate 13, a second pull plate 14, a first buffer rod 15, and a first buffer spring 16. The first pull plate 13 is disposed at the end of the front pull rod 11, and the front pull rod 11 is used to connect the driving component, that is, the two ends of the front pull rod 11 are respectively connected to the first pull plate 13 and the driving component. The first buffer rod 15 is disposed on the second pull plate 14 and has a first end 150. The first pull plate 13 is movably disposed on the first buffer rod 15. The first buffer spring 16 is sleeved on the first buffer rod 15, and the two ends of the first buffer spring 16 abut against the first end 150 and the first pull plate 13, respectively. The second pull plate 14 is disposed at the end of the rear pull rod 12.

[0020] The transport component 2 includes a positioning plate 21, a slider 22, and a limiting rod 23. The slider 22 is slidably mounted on the positioning plate 21, and the limiting rod 23 is mounted on the positioning plate 21. The limiting rod 23 is located on the moving path of the slider 22. The slider 22 is connected to the rear pull rod 12, that is, the two ends of the rear pull rod 12 are respectively connected to the slider 22 and the second pull plate 14. The slider 22 is used to carry items, and a pallet can also be mounted on the slider 22 to load items.

[0021] The driving component drives the front pull rod 11 to move. If the first pull plate 13 touches the second pull plate 14, then the rear pull rod 12 pushes the slider 22 to move, so that the slider 22 moves away from the limit rod 23. The slider 22 moves away to the set position, and the driving component drives the front pull rod 11 to move in the opposite direction.

[0022] If the first pull plate 13 compresses the first buffer spring 16, then the first buffer rod 15 drives the second pull plate 14 to move, and the rear pull rod 12 pulls the slider 22 to move until the slider 22 abuts against the end of the limit rod 23. At this time, the first pull plate 13 continues to compress the first buffer spring 16, and the driving member drives the front pull rod 11 to move in the opposite direction. In this way, the slider 22 has a buffering effect when it abuts against the limit rod 23.

[0023] The buffer assembly 1 also includes a first universal bearing 17, which is threadedly connected to the front pull rod 11. The first universal bearing 17 is also used to sleeve the drive component. The first end of the first universal bearing 17 is sleeved on the drive component, and the second end of the first universal bearing 17 is threadedly connected to the front pull rod 11. A first nut 105 is sleeved on the external thread of the front pull rod 11. The first nut 105 is used to abut against the first universal bearing 17 to prevent the internal thread on the first universal bearing 17 from loosening with the external thread on the front pull rod 11.

[0024] The buffer assembly 1 also includes a second universal bearing 18, which is threadedly connected to the rear pull rod 12 and rotatably connected to the slider 22. A second nut 106 is fitted onto the external thread of the rear pull rod 12. The second nut 106 is used to abut against the second universal bearing 18 to prevent the internal thread on the second universal bearing 18 from loosening with the external thread on the rear pull rod 12. The first nut 105 and the second nut 106 rotate in different directions.

[0025] The carrier assembly 2 also includes a connecting plate 24 and a connecting rod 25. The connecting plate 24 is mounted on the slider 22. The positioning plate 21 is provided with a sliding hole 26. The connecting plate 24 passes through the sliding hole 26. The connecting rod 25 is mounted on the connecting plate 24 and is located below the positioning plate 21. The second universal bearing 18 is sleeved on the connecting rod 25. The positioning plate 21 is fixed to the bracket (not shown in the figure) by a screw. In this way, the slider 22 slides on the upper surface of the positioning plate 21. The slider 22 overlaps on both sides of the sliding hole 26. The length of the sliding hole 26 is the length of movement of the slider 22. The slider 22 is not easy to fall off the positioning plate 21. The sliding hole 26 is an elongated hole.

[0026] The carrier component 2 also includes a first support 27, a second support 28, and a slide rod 29. The first support 27 and the second support 28 are disposed on the positioning plate 21 and are located at both ends of the sliding hole 26 along its length. The slide rod 29 is disposed on the first support 27 and the second support 28 and is located above the sliding hole 26. The slider 22 is slidably disposed on the slide rod 29 and can move on the slide rod 29. The first support 27 and the second support 28 are both on the movement path of the slider 22.

[0027] The limiting rod 23 is set on the first support 27 and is threadedly connected to the first support 27. The limiting rod 23 passes through the first support 27. By rotating the limiting rod 23, the limiting rod 23 can move away from or closer to the slider 22. In other words, the distance between the limiting rod 23 and the slider 22 can be adjusted.

[0028] The positioning plate 21 is provided with a first limiting groove 211 and a second limiting groove 212. A first support 27 is disposed in the first limiting groove 211 and a second support 28 is disposed in the second limiting groove 212. The first limiting groove 211 and the second limiting groove 212 are fixed to the positioning plate 21 by screws. The positioning plate 21 has multiple threaded holes for fitting the screws. The position of the first support 27 in the first limiting groove 211 can move, and the position of the second support 28 in the second limiting groove 212 can move. In this way, the distance between the first support 27 and the second support 28 can be adjusted, that is, the distance that the slider 22 moves on the slider 29 can be adjusted.

[0029] The buffer assembly 1 also includes a second buffer rod 101 and a second limiting spring 102. The second buffer rod 101 is disposed on the second pull plate 14, and the first pull plate 13 is slidably disposed on the second buffer rod 101. The second buffer rod 101 has a second end 103. The second limiting spring 102 is sleeved on the second buffer rod 101, and the two ends of the second limiting spring 102 abut against the second end 103 and the first pull plate 13, respectively.

[0030] The second buffer rod 101 and the first buffer rod 15 are located on both sides of the second pull plate 14, and the rear pull rod 12 is connected to the center of the second pull plate 14, so that the second pull plate 14 and the rear pull rod 12 are subjected to uniform force.

[0031] Similarly, the second buffer rod 101 and the first buffer rod 15 are located on both sides of the first pull plate 13, and the front pull rod 11 is connected to the center of the first pull plate 13. When the first pull plate 13 slides on the second buffer rod 101 and the first buffer rod 15, the front pull rod 11 and the first pull plate 13 are subjected to uniform force.

[0032] The second buffer rod 101 and the first buffer rod 15 simultaneously ensure that the first pull plate 13 and the second pull plate 14 are subjected to uniform force, so that the first pull plate 13 and the second pull plate 14 can maintain balance.

[0033] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
