Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a lifting and adjusting mechanism for a shelf entry and exit device. Background Technology

[0002] In the field of automated manufacturing, belt drive is one of the most efficient drive methods for rack-mounted inbound and outbound devices. It typically consists of a motor, a support frame, and the belt itself. The advantages of this drive structure are low cost, low noise, and ease of maintenance. However, in actual production activities, long-term operation can cause the belt tension to loosen. This not only reduces the accuracy of the drive but can also lead to dangerous accidents in severe cases. Therefore, it is particularly necessary to include a structure in the belt drive mechanism to adjust the belt tension.

[0003] A search revealed that patent CN202322449025.7 discloses a belt tensioning mechanism, including a belt fixing assembly, an adjusting bolt, and an adjusting bolt fixing seat. One end of the adjusting bolt is threaded through the adjusting bolt fixing seat and connected to the belt fixing assembly. Rotating the adjusting bolt causes the belt fixing assembly to move up and down on the base plate along the direction of the belt extension. The belt fixing assembly includes a belt tensioning adjustment fixing plate, an upper belt toothed pressure plate, and a fastening bolt. One end of the belt is fixed between the belt tensioning adjustment fixing plate and the upper belt toothed pressure plate, which is detachably fixed to the belt tensioning adjustment fixing plate. Two oblong holes are respectively provided on both sides of the belt tensioning adjustment fixing plate. One end of the fastening bolt passes through the oblong holes and is threaded to the base plate. One end of the adjusting bolt is threaded through the adjusting bolt fixing seat and connected to the belt tensioning adjustment fixing plate. Loosening the fastening bolt and rotating the adjusting bolt causes the belt fixing assembly to move closer to or further away from the adjusting bolt fixing seat, thereby adjusting the belt tension.

[0004] However, research has revealed that the existing structure is quite complex, with many parts, and the adjusting bolts are inconvenient for operators to adjust when adjusting the tightness. The structure and layout design are unreasonable, and the overall structure is not simple enough. Therefore, it is necessary to propose a more advanced adjustment mechanism. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a lifting and adjusting mechanism for a shelving inbound and outbound device, which can effectively solve the above-mentioned problems.

[0006] To achieve the above requirements, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A lifting and adjusting mechanism for a shelving inbound / outbound device is provided, comprising an upright, a belt parallel to the upright, and a motor for driving the belt to rotate longitudinally; it also includes an upright plate and an adjusting plate attached to one side wall of the upright plate, the gap between the adjusting plate and the upright plate forming a clamping position for clamping and fixing the belt; two adjusting plates are provided, located at the upper and lower ends of the upright plate respectively, and each of the upper and lower end surfaces of the upright plate has a notch or groove penetrating its side walls, and the adjusting plate has an extension extending into the notch or groove; the adjusting plate is detachably connected to the upright plate by fastening bolts, and the through hole on the upright plate that matches the fastening bolt is longitudinally elongated; an adjusting bolt is longitudinally threaded through the extension, and the lower end of the adjusting bolt is threadedly connected to the bottom surface of the notch or groove.

[0008] The lifting and adjusting mechanism of the shelving inbound and outbound device of this utility model includes a positioning part for a positioning belt on the side wall of the adjusting plate facing the upright plate.

[0009] The lifting and adjusting mechanism of the shelving inbound and outbound device of this utility model includes a positioning part that is a groove running longitudinally through both the upper and lower ends of the adjusting plate. When assembled in place, the bottom surface of the groove presses the belt against the side wall of the upright plate.

[0010] The lifting and adjusting mechanism of the shelving entry and exit device of this utility model has a horizontal strip-shaped through hole on the bottom surface of the groove, and the strip-shaped through hole has a plurality of holes and is evenly arranged longitudinally.

[0011] The lifting and adjusting mechanism of the shelving inbound and outbound device of this utility model includes an avoidance hole on the extension for the belt to pass through, the avoidance hole penetrating the extension.

[0012] The lifting and adjusting mechanism of the shelving inbound and outbound device of this utility model includes two adjusting bolts located on the left and right sides of the belt, respectively.

[0013] The lifting and adjusting mechanism of the shelving entry and exit device of this utility model includes multiple fastening bolts, which are evenly divided into two groups and arranged on the left and right sides of the belt.

[0014] The lifting and adjusting mechanism of the shelving entry and exit device of this utility model has the notch and the two end side walls of the extension as vertical surfaces. When assembled, the two end side walls of the extension slide longitudinally against the two end side walls of the notch.

[0015] The lifting and adjusting mechanism of the shelving inbound and outbound device of this utility model includes a limiting bolt that runs through the front and rear sides of the upright plate. One end of the limiting bolt that runs through the upright plate is provided with a limiting part. The adjusting plate is provided with a limiting guide groove corresponding to the limiting part. When assembled in place, the limiting part extends into the limiting guide groove.

[0016] The advantages of this utility model are as follows: Compared with the existing technology, the overall structure of this utility model is simple. The length of the belt can be adjusted by the cooperation of the adjusting plate, the extension part and the upright plate, and the tension of the belt can be adjusted easily.

[0017] Specifically, during installation, both ends of the belt are secured to the side wall of the upright plate using two adjusting plates and fastening bolts. The adjusting bolts are threaded through the extension and connected to the bottom thread of the notch, and then tightened. After assembly, when the belt needs to be loosened, first loosen the upper fastening bolt to a certain extent (but not completely), then loosen the adjusting bolt upwards to move the extension upwards synchronously, thereby moving the upper adjusting plate upwards. Once in position, tighten the fastening bolt. This increases the distance between the upper and lower adjusting plates, thus increasing the distance between the two ends of the belt, allowing the belt to be loosened. To tighten the belt, reverse the operation of the upper adjusting plate or adjust the lower adjusting plate upwards to tighten the belt again.

[0018] An additional advantage of this adjustment method is that the tightening bolts can provide a pulling force on the belt during the adjustment process. This simplifies the overall structure and avoids the disadvantage of having to manually tighten the belt and fix it again due to the reduction of the belt clamping structure.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The lifting and adjusting mechanism of the shelving inbound / outbound device in the preferred embodiment of this utility model, such as... Figure 1-5As shown, this mechanism includes a column 10, a belt 20 arranged parallel to the column 10, and a motor 30 for driving the belt 20 to rotate longitudinally. Specifically, the motor 30 is located at the lower end of the column 10. The mechanism also includes a vertical plate 40 and an adjusting plate 50 attached to one side wall of the vertical plate 40. The adjusting plate 50 has a slider 60 at its end facing away from the vertical plate, and the slider 60 is longitudinally slidably connected to the column 10. The gap between the adjusting plate 50 and the vertical plate 40 forms a clamping position for holding and fixing the belt 20. During assembly, the end of the belt 20 is placed between the adjusting plate 50 and the vertical plate 40 and clamped by the adjusting plate 50. Two adjusting plates 50 are provided, located at the upper and lower ends of the vertical plate 40 respectively, to clamp and press the two ends of the belt 20 against the vertical plate 40. During assembly, the lower end of the belt 20 passes over the pulley 21 on the shaft of the motor 30 and extends between the lower adjusting plate 50 and the upright plate 40, while the upper end of the belt 20 passes over the upper pulley 22 on the upper end of the column 10 and extends between the upper adjusting plate 50 and the upright plate 40.

[0031] Furthermore, both the upper and lower ends of the upright plate 40 are provided with notches 41 that penetrate the side walls on both sides. The adjusting plate 50 is provided with an extension 51 that extends into the notch 41. The adjusting plate 50 is detachably connected to the upright plate 40 by fastening bolts 70. The through hole 80 on the upright plate 40 that matches the fastening bolt 70 is longitudinally elongated. The extension 51 is longitudinally threaded with an adjusting bolt 90. The lower end of the adjusting bolt 90 is threaded to the bottom surface of the notch 41. The elongated through hole 80 is designed so that when the extension 51 is moved up and down by the adjusting bolt 90, the fastening bolt 70 can move up and down synchronously with the adjusting plate 50, thus avoiding conflicts in the adjustment operation.

[0032] Compared with existing technologies, the present invention has a simple overall structure. The length of the belt 20 can be adjusted by the cooperation of the adjusting plate 50, the extension part 51 and the upright plate 40, and the tension of the belt 20 can be adjusted easily.

[0033] Specifically, during installation, the two ends of the belt 20 are fastened to the side wall of the upright plate 40 by the cooperation of the two adjusting plates 50 and the fastening bolts 70. The adjusting bolts 90 are threaded through the extension 51 and connected to the bottom thread of the notch 41 and tightened. After assembly, when it is necessary to loosen the belt 20, the upper fastening bolts 70 are loosened to a certain extent but not completely to tighten the belt. Then, the adjusting bolts 90 are loosened upwards to move the extension 51 upwards, thereby moving the upper adjusting plates 50 upwards. After they are in place, the fastening bolts 70 are tightened. At this time, the distance between the upper and lower adjusting plates 50 increases, which in turn increases the distance between the two ends of the belt 20, thus loosening the belt 20. If it is necessary to tighten the belt 20, the upper adjusting plate 50 is operated in reverse or the lower adjusting plate 50 is adjusted upwards to tighten the belt 20 again.

[0034] An additional advantage of this adjustment method is that the tightening bolt 70 can provide a pulling force on the belt 20 during the adjustment process. This simplifies the overall structure and avoids the disadvantage of needing to manually tighten and fix the belt due to the reduction of the belt clamping structure.

[0035] In this embodiment, the adjusting plate 50 is provided with a positioning part for the positioning belt 20 on the side wall facing the upright plate 40. Specifically, the positioning part is a groove 100 that runs longitudinally through both the upper and lower ends of the adjusting plate 50. The width of the groove 100 is the same as the width of the belt. When assembled, the bottom surface of the groove 100 presses the belt against the side wall of the upright plate 40 to position the belt, prevent the belt from tilting, and facilitate installation.

[0036] In this embodiment, a horizontal strip-shaped through hole 101 is provided on the bottom surface of the groove 100. Multiple strip-shaped through holes 101 are provided and are evenly arranged in the longitudinal direction so that the bottom surface of the groove 100 forms horizontal stripes, thereby increasing the friction between the bottom surface of the groove 100 and the belt and reducing the risk of the belt accidentally coming loose.

[0037] In this embodiment, the extension 51 is provided with a clearance hole 510 for the belt to pass through. The clearance hole 510 passes through the extension 51, so that the belt can pass through and also serves as a limiting and guiding function for the belt 20. It also facilitates the alignment of the belt with the groove 100 by the operator during the assembly process.

[0038] In this embodiment, there are two adjusting bolts 90 located on the left and right sides of the belt 20, respectively. At the same time, there are multiple fastening bolts 70, which are divided into two groups and arranged on the left and right sides of the belt, respectively, so as to ensure that the left and right ends of the belt and the adjusting plate 50 can be subjected to balanced upward tension or downward pressure.

[0039] In this embodiment, both the notch 41 and the two end sidewalls of the extension 51 are vertical surfaces. When assembled, the two end sidewalls of the extension 51 slide and fit longitudinally with the two end sidewalls of the notch 41, so as to guide and limit the up and down movement of the extension 51. At the same time, when the extension 51 is adjusted inward, it plays a role in positioning and preventing movement.

[0040] In this embodiment, a limiting bolt 120 is provided through the front side wall of the upright plate 40. A limiting part 121 is provided at one end of the limiting bolt 120 that passes through the upright plate 40. The outer side wall of the limiting part 121 is a smooth surface and its cross-section can be circular, square or other polygonal. Furthermore, a limiting guide groove 130 is provided on the adjusting plate 50 corresponding to the limiting part. When assembled in place, the limiting part 121 extends into the limiting guide groove 130 to further guide and limit the up and down movement of the adjusting plate 50.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
