Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to an object guiding device for a conveyor. Background Art

[0002] A conveyor is a commonly used device for transporting objects. In actual use, it is often used in conjunction with a mechanical gripper to transport objects over short distances. However, during use, due to the uneven mass of the objects (usually boxed objects), the pressure inside is uneven, which causes the objects to easily shift when transported on the conveyor. Or due to the inertia of the objects themselves, the objects shift during arc transportation, causing the objects to fall off the conveyor, fall and be damaged, or get stuck on the conveyor, causing blockage of objects on the conveyor.

[0003] For example, a material transport deflection corrector proposed in CN202111206219.3 provides a material transport deflection corrector that performs multiple deflection corrections and can adjust the amount of deflection correction by respectively arranging deflection correction structures in the middle and on both sides of the bottom side of the conveyor belt. The deflection correction positioning assembly and the support frame are provided. A deflection correction positioning assembly is provided at the bottom of the conveyor belt, and the conveyor belt is placed on the support frame. The deflection correction positioning assembly and the support frame are correspondingly engaged. A lateral adjustment assembly is provided at the engaging position of the support frame and the deflection correction positioning assembly. The support frame includes side rollers, middle rollers, support rods, fixed frames, splints, screw motors, screws, sliding sleeves, top shafts, fixed arms, deflection arms, articulated shafts, and main frames. Multi-layer deflection correction can be formed on both sides and in the middle. The deflection correction is stable, and the size of the middle roller can be replaced. However, the above-mentioned problems are not solved.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0031] Hereinafter, a conveyor object guiding device according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 - Fig. 9 As shown, the object guiding device of the conveyor includes a bracket assembly, and the bracket assembly includes a frame 1 and a center frame 2. A supporting foot is provided below the frame 1, and a center frame 2 is provided on the inner side of the frame 1. A support roller 6 is rotatably provided on the frame 1. A fixed frame 3 is provided below the frame 1, and a motor 4 is provided on the fixed frame 3. The motor 4 is connected to the support roller 6 through a transmission assembly. A belt groove is provided in the middle of the support roller 6, and the middle part of the belt groove is protruding. A conveyor belt 7 is installed on the support roller 6. The object guiding device of the conveyor also includes: a centering device provided in the middle of the frame 1, which can center the object above; an anti-deflection device provided at one end of the centering device, which can guide the object above.

[0032] Preferably, anti-deflection devices are provided at both ends of the centering device to prevent secondary small deviations of objects due to the height difference between the centering device and the conveyor belt when the objects pass through the centering device. Anti-falling devices are provided on both sides of the head end of the anti-deflection device to assist the objects above to be centerable and prevent the objects from falling over.

[0033] In a specific embodiment: the object guiding device is fixed on the use site through supporting feet, and multiple object guiding devices can be connected in sequence as needed.

[0034] When in use, the motor 4 is started by an external power source, and drives the support roller 6 and the conveyor belt 7 to rotate through the transmission component, so that the objects on the support roller 6 and the conveyor belt 7 are transported and moved.

[0035] like Figure 1 , Figure 4 and Fig. 9As shown, the conveyor object guiding device includes a centering device, which is composed of a guide roller 17 rotatably installed in the middle of the frame 1. At least one guide roller 17 is installed in the middle of the frame 1. A push plate 18 is provided on the guide roller 17, and at least three push plates 18 are arranged on the guide roller 17 in an inclined manner.

[0036] Among them, the push plates 18 are arranged from the middle of the guide roller 17 to the outside from small to large, and the outer end of the push plate 18 inclined in the middle of the guide roller 17 and the inner end of the outer inclined push plate 18 are at the same distance from the middle of the guide roller 17, and a notch is provided at one end of the push plate 18.

[0037] In a specific embodiment, the guide roller 17 is connected to the motor 4 through a transmission assembly. When the object moves to the front of the guide roller 17, the object can move to the top of the push plate 18 through the notch of the push plate 18. When the undeflected object is above the push plate 18, the object is on the push plates 18 of the same size on both sides, thereby passing through the centering device; When the offset object is above the push plate 18 (such as offset to the right), the object is on the push plates 18 of different sizes on both sides. The larger push plate 18 on the right will push the object, while the larger push plate 18 on the left cannot contact the object due to the offset of the object, thereby centering the object.

[0038] like Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the object guiding device of the conveyor includes an anti-deviation device, which includes a mounting plate 8, a stop roller 10 and a movable plate 9. The mounting plate 8 is arranged below the frame 1, and the movable plate 9 is arranged above the mounting plate 8 through a slide rail 11, and is located below the center frame 2. A compression spring 12 is arranged between the movable plates 9 and the movable plates 9. A stop roller 10 is rotatably arranged above the movable plate 9, and the upper end of the stop roller 10 is higher than the upper end of the support roller 6. The stop roller 10 is located between the center frame 2 and the frame 1, and a gap is left between the stop roller 10 and the center frame 2 and the frame 1.

[0039] Among them, the inner side of the slide rail 11 is provided with evenly arranged card grooves, the mounting plate 8 is arranged in the slot corresponding to the slide rail 11, and the inner side of the slot is provided with a protruding plug.

[0040] In a specific embodiment, the object moves to the front of the blocking roller 10 through the support roller 6 and the conveyor belt. When the undeflected object is in front of the stop roller 10, the left and right sides of the object press down the stop roller 10 at the same time, so that the moving plate 9 compresses the spring 12 and moves downward, so that the object passes under the drive of the conveyor belt; When the offset object is in front of the stop roller 10, one side of the object first presses down the stop roller 10, so that the side of the movable plate 9 first compresses the spring 12 and moves downward, so that the movable plate 9 is tilted, so that the plug of the mounting plate 8 is stuck in the slot, thereby preventing the movable plate 9 from moving downward, so that the object first contacts one side of the stop roller 10 and cannot move forward, and then driven by the conveyor belt, the other end of the object contacts the stop roller 10 again, so that the stop rollers 10 on both sides are pressed down at the same time, the plug is disengaged from the slot, and the movable plate 9 compresses the spring 12 and moves downward, so that the object passes under the drive of the conveyor belt, and the object is guided.

[0041] like Figure 1 , Figure 4 and Figure 8 As shown, the object guiding device of the conveyor includes an anti-falling device, which includes a fixed rod 13, a first guide plate 14 and a roller 16. The fixed rod 13 is arranged on the frame 1, and the first guide plate 14 is rotatably arranged on the fixed rod 13. A torsion spring is arranged between the first guide plate 14 and the fixed rod 13, and rollers 16 are arranged on the side and end of the first guide plate 14.

[0042] Preferably, a second guide plate 15 is rotatably provided at the end of the first guide plate 14 , a torsion spring is provided between the first guide plate 14 and the second guide plate 15 , and rollers 16 are provided on the sides of the first guide plate 14 and the second guide plate 15 and on the end of the second guide plate 15 .

[0043] The elastic coefficient of the torsion spring between the first guide plate 14 and the fixing rod 13 is greater than the elastic coefficient of the torsion spring between the first guide plate 14 and the second guide plate 15 .

[0044] In a specific embodiment: when the lower end of the object contacts the anti-bias device, the upper end of the object contacts the roller 16 on the first guide plate 14 or the second guide plate 15 (depending on the size of the object and the offset distance of the object), thereby preventing the object from tipping over due to unstable center of gravity caused by the contact of the lower end (suitable for objects with an upper center of gravity). At the same time, since the elastic coefficient of the torsion spring between the first guide plate 14 and the fixing rod 13 is greater than the elastic coefficient of the torsion spring between the first guide plate 14 and the second guide plate 15, When an undeflected object passes through, the object will contact the roller 16 on the first guide plate 14 or the second guide plate 15 at the same time, so that the same guide thrust is generated on both sides, and the object passes normally; When the deflected object passes, one side of the object contacts the roller 16 on the first guide plate 14, and one end contacts the roller 16 on the second guide plate 15, and the torsion springs with different elastic coefficients on both sides are deformed, thereby generating thrusts of different magnitudes, thereby assisting the object in being guided.

[0045] Working principle: The object guiding device is fixed on the use site by supporting feet. Multiple object guiding devices can be connected in sequence as needed. When in use, the motor 4 is started by an external power supply, and the support roller 6 and the conveyor belt 7 are driven to rotate through the transmission component, so that the objects on the support roller 6 and the conveyor belt 7 are transported and moved, and then the objects are moved to the front of the stop roller 10 through the support roller 6 and the conveyor belt. When the offset object is in front of the stop roller 10, one side of the object first presses down the stop roller 10, so that the side of the moving plate 9 first compresses the spring 12 and moves downward, so that the moving plate 9 tilts, so that the plug of the mounting plate 8 is stuck in the slot, thereby preventing the moving plate 9 from moving downward, so that the side of the object that first contacts the stop roller 10 cannot move forward, and then driven by the conveyor belt, the other end of the object contacts the stop roller 10 again, so that the stop rollers 10 on both sides are pressed down at the same time, so that the plug is disengaged from the card. The groove makes the moving plate 9 compress the spring 12 and move downward, so that the object passes through under the drive of the conveyor belt, thereby guiding the object. At the same time, when the offset object passes through, one side of the object contacts the roller 16 on the first guide plate 14, and one end contacts the roller 16 on the second guide plate 15. The torsion springs with different elastic coefficients on both sides are deformed, thereby generating thrusts of different sizes, thereby assisting the object to be centered. Then, the guide roller 17 is connected to the motor 4 through the transmission assembly. When the object moves in front of the guide roller 17, the notch of the push plate 18 allows the object to be moved above the push plate 18. Then, the offset object will be on the push plates 18 of different sizes on both sides (such as offset to the right side), and the larger push plate 18 on the right will push the object, while the larger push plate 18 on the left cannot contact the object due to the offset of the object, thereby centering the object.
