[0003] According to CN212654944U, a multi-stage synchronous chain drive wood rod conveying device is disclosed. This technology discloses a technical solution including "a frame structure for supporting the entire device, with multiple symmetrically arranged bearing seat assemblies mounted on the top of the frame structure, and transmission roller assemblies for supporting and conveying the rods mounted between the bearing seat assemblies via transmission shafts; a protective structure is provided on the top of the frame structure and on the side of the transmission roller assemblies; adjacent transmission shafts are connected by a multi-stage chain drive mechanism, and the first-stage transmission shaft is connected to a power device for driving its rotation." This technology has the technical effect of "using a multi-stage chain drive to automate the conveying of wood rods during furniture production, thereby replacing the traditional manual handling or transfer process, and greatly improving the conveying efficiency of wood."

[0004] Existing bar storage and handling equipment, when using roller conveyors to transport multiple bars simultaneously, suffers from a lack of effective spacing control and isolation mechanisms. As a result, the bars come into contact, collide, and rub against each other during transport, leading to scratches on the bar surface, damage to the coating, or geometric deformation. This seriously affects product quality. In addition, the noise and impact generated can reduce the stability and service life of the equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bar storage and handling device. By driving vertical rollers to move synchronously and equidistantly through a symmetrical linkage mechanism, multiple guide channels of equal width are formed, enabling low-resistance parallel guidance of multiple bars and significantly improving batch conveying efficiency and adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bar storage and handling device, comprising a roller conveyor, wherein the roller conveyor is equipped with a guiding mechanism for guiding and isolating the bars during the conveying process, the guiding mechanism comprising:

[0015] Beneficial effects

[0016] This utility model provides a bar stock storage and handling device. Compared with the prior art, it has the following advantages:

[0017] 1. When the drive shaft of the drive component rotates, the guide grooves with the same contour arranged symmetrically on its surface simultaneously push the cams on both sides, causing the two carriages to move in equidistant linear motions along the balance bar with the center of the shaft as the symmetrical point.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a bar storage and handling device, including a roller conveyor 1, a guiding mechanism 2 on the roller conveyor 1 for guiding and isolating the bars during the conveying process, the guiding mechanism 2 including:

[0026] The support assembly 21 includes a support frame 211 fixed inside the lower end of the roller conveyor 1;

[0027] The adjustment assembly 22 includes a shaft frame 221 fixed to the middle of the upper end of the support frame 211. A shaft rod 222 is rotatably mounted between the left and right ends of the shaft frame 221. A plurality of guide grooves 223 are symmetrically arranged on the outer wall of the shaft rod 222. A balance bar 224 is fixed between the left and right ends of the shaft frame 221. A slide 225 is slidably mounted on the balance bar 224. A cam 226 is rotatably mounted at the rear end of the slide 225, and the cam 226 is located inside the corresponding guide groove 223. A drive component 227 is provided on the shaft frame 221 for driving the shaft rod 222 to rotate.

[0028] The limiting component 23 includes a crossbeam 231 fixed to the upper end of the slide 225, and a plurality of vertical rollers 232 are rotatably mounted on the upper end of the crossbeam 231.

[0029] In this embodiment, when the drive component 227 drives the shaft 222 to rotate, the guide grooves 223 with the same contour arranged symmetrically on its surface simultaneously push the cams 226 on both sides, causing the two carriages 225 to move in opposite directions along the balance bar 224 with the center of the shaft 222 as the symmetrical point. This drives the cross frame 231 and vertical rollers 232 fixed to the upper end of the carriages 225 to always maintain a symmetrical distribution. The vertical rollers 232 form equally spaced guide channels. The vertical rollers 232 in each guide channel adopt a rolling contact method, and their axes are arranged perpendicular to the conveying direction, providing synchronous low-resistance guidance for multiple bars. Multiple guide channels of equal width are formed in a single adjustment, which meets the process requirements of parallel conveying of multiple bars and significantly improves the efficiency and adaptability of batch material conveying.

[0030] Specifically, brackets 212 are fixed at both the front and rear ends of the top of the support frame 211, and slide rails 213 are fixed at the top of the brackets 212. Slider blocks 214 are fixed at both the front and rear ends of the bottom of the cross frame 231, and the sliders 214 are slidably mounted on the slide rails 213. When the adjusting component 22 drives the slide 225 to move laterally along the balance bar 224, the sliders 214 slide synchronously along the slide rails 213, providing additional horizontal guidance and vertical support for the cross frame 231 and the vertical roller 232.

[0031] In this embodiment, the cooperation between the slide rail 213 and the slider 214 effectively enhances the anti-overturning ability and motion stability of the vertical roller 232 when subjected to the lateral pressure of the bar, prevents jamming or shaking caused by single-point support, ensures that the vertical roller 232 spacing adjustment process is smooth and accurate, and significantly improves the structural rigidity and load-bearing capacity of the entire guide mechanism 2, extending the service life of the equipment.

[0032] Specifically, the drive component 227 includes a driven pulley 2271 fixed to one end of the shaft 222, a servo motor 2272 mounted at the rear end of the shaft frame 221, a drive pulley 2273 fixed at the output end of the servo motor 2272, and a belt 2274 installed between the drive pulley 2273 and the driven pulley 2271.

[0033] In this embodiment, the servo motor 2272 drives the active pulley 2273 to rotate, and the rotation is transmitted to the driven pulley 2271 fixed at one end of the shaft 222 via the belt 2274, thereby driving the shaft 222 to rotate.

[0034] Specifically, the crossbeam 231 is located between adjacent rollers on the roller conveyor 1, and the rolling direction of the vertical roller 232 is consistent with the conveying direction of the roller conveyor 1.

[0035] In this embodiment, the vertical roller 232 only contacts the side of the bar during the bar conveying process to achieve the guiding function, completely avoiding motion interference with the roller at the bottom of the bar.

[0036] Specifically, the guide groove 223 is an arc-shaped inclined groove, and the rolling direction of the vertical roller 232 is consistent with the conveying direction of the roller conveyor 1.

[0037] In this embodiment, the shaft 222 converts rotational motion into linear motion through the precise cooperation between the symmetrically distributed guide grooves 223 on its surface and the cam 226, thereby driving the slides 225 on the left and right sides to move synchronously and symmetrically at equal distances along the balance bar 224.

[0038] Specifically, the axis of the balance bar 224 is parallel to the axis of the shaft 222.

[0039] In this embodiment, the axis of the balance bar 224 and the axis of the shaft 222 are strictly parallel. They are precisely positioned and installed via the shaft bracket 221, forming a stable parallel motion reference. This parallelism design ensures that the sliding trajectory of the carriage 225 on the balance bar 224 is always perpendicular to the axis of the shaft 222, keeping the movement trajectory of the cam 226 within the guide groove 223 stable and completely avoiding motion interference and additional wear caused by non-parallel axes. Simultaneously, it ensures the synchronicity and straightness of the movement of the left and right carriages 225, ensuring that the vertical roller 232 maintains a precise symmetrical distribution during adjustment.

[0040] The working principle and usage process of this utility model are as follows: First, the servo motor 2272 drives the active pulley 2273 to rotate, which is then transmitted to the driven pulley 2271 fixed at one end of the shaft 222 via the belt 2274, thereby driving the shaft 222 to rotate. When the shaft 222 rotates, the guide grooves 223 with the same contour arranged symmetrically on its surface synchronously push the cams 226 on both sides, causing the two slides 225 to move in equidistant linear motion along the balance bar 224 with the center of the shaft 222 as the symmetrical point, thereby driving the cross frame 231 and vertical roller 232 fixed at the upper end of the slide 225 to always maintain a symmetrical distribution. The vertical rollers 232 form equally spaced guide channels, and the vertical rollers 232 in each guide channel adopt a rolling contact method, with their axes arranged perpendicular to the conveying direction, providing synchronous low-resistance guidance for multiple bars. Multiple guide channels of equal width are formed in a single adjustment, meeting the process requirements of parallel conveying of multiple bars, and significantly improving the efficiency and adaptability of batch material conveying.
