Description

Technical Field

[0001] This invention relates to the field of material conveying equipment, and more specifically to a material alignment conveying module and a material alignment positioning method thereof. Background Technology

[0002] During production, materials are transported via belts or conveyor rollers. Different mechanisms frequently grab and move the materials on the belts. However, when these mechanisms grab the materials, the material positioning is often inaccurate or inconsistent, resulting in grabbing errors or the materials falling off the conveyor. Therefore, accurate positioning of the materials during grabbing is crucial.

[0003] Currently, although there are specially designed positioning methods on the market, they still have significant shortcomings: 1. Fixed guide devices are designed on both sides of the belt to vertically position the material. However, the disadvantage of this positioning method is that if the positioning is too tight, the disc is prone to jamming; if the positioning is too loose, the vertical positioning error is large, and the downstream disc-grabbing mechanism will not grasp the material accurately.

[0004] 2. If the material tray is to stop on the belt, a mechanical blocking positioning method is often used laterally. The disadvantage of this method is that if the belt speed is too fast or the elasticity of the material tray is too great, the impact on the lateral blocking mechanism will often cause a rebound, which can easily damage the material and also cause excessive lateral positioning error. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying module capable of precise material positioning. Vertical positioning is achieved by using two vertical cylinders to push the material upright, and horizontal positioning is achieved by using a horizontal cylinder to push the material back. This solves the problems of traditional positioning methods, which are prone to jamming in the vertical direction and errors due to rebound in the horizontal direction. To achieve the above objective, this invention provides the following technical solution: A material alignment conveying module includes a machine base with a conveying module mounted on the machine base. Material is conveyed from the first end to the last end of the conveying module. Vertical cylinder assemblies are respectively mounted on both sides of the machine base along the material conveying direction. The output shafts of the two vertical cylinder assemblies extend inward perpendicular to the material conveying direction to vertically position the material. A horizontal cylinder assembly is mounted at the last end of the machine base, with its output shaft extending in the opposite direction to the material conveying direction to laterally position the material.

[0006] The present invention is further configured such that: a position sensor electrically connected to the conveying module is provided on the machine base, the position sensor is located between the vertical cylinder and the horizontal cylinder along the material conveying direction, and the position sensor controls the conveying module to stop conveying when it senses material.

[0007] The present invention is further configured such that: the conveying module includes a conveying motor and a conveying belt, the conveying belt has a gap, the gap extends along the material conveying direction, the transverse cylinder module includes a transverse cylinder disposed at the bottom of the conveying module, a stop rod is connected to the output shaft of the transverse cylinder, the stop rod extends above the gap for pushing the material, and the transverse cylinder drives the stop rod to move along the length direction of the gap.

[0008] The present invention is further configured such that: the conveyor belt has two gaps, the two gaps are arranged along the width direction of the conveyor belt, and a stop bar is respectively provided in the two gaps.

[0009] The present invention is further configured such that: a connecting plate is fixed on the output shaft of the transverse cylinder, and both of the stop rods are fixed on the connecting plate.

[0010] The present invention is further configured such that: the vertical cylinder assembly includes a vertical cylinder, and a push plate is fixed on the output shaft of the vertical cylinder, the push plate extending along the material conveying direction.

[0011] The present invention is further configured such that both ends of the push plate in the length direction are inclined outward.

[0012] The present invention is further configured such that: the vertical cylinder assembly further includes a mounting plate disposed on the machine base, the mounting plate is provided with an adjustment plate, the adjustment plate is adjustablely mounted on the mounting plate in a direction perpendicular to the material conveying direction, and the vertical cylinder is fixed to the adjustment plate.

[0013] Furthermore, the present invention also proposes a material alignment and positioning method, including the aforementioned material alignment and conveying module, and further comprising the following steps: S1: The conveying module conveys the material from the beginning to the end, and when the material is conveyed to a preset position, the conveying module stops conveying; S2: The output shafts of the vertical cylinder assemblies on both sides extend inward by a fixed length, and the output shafts push the material for vertical positioning; S3: The output shafts of the horizontal cylinder assembly extend inward by a fixed length in the opposite direction to the material conveying, and the output shafts push the material for horizontal positioning.

[0014] The present invention is further configured such that: in step S1, when the position sensor senses the material, the conveying module stops conveying.

[0015] Compared with the prior art, the present invention has at least the following advantages: 1. It achieves active and flexible precise positioning in the vertical direction. After the material is conveyed to the predetermined position, the output shafts of the vertical cylinder assemblies on both sides extend inward, avoiding the contradiction of "getting stuck when tightened and deviating when loosened" in traditional fixed guides. Through the fixed output stroke of the vertical cylinders, it not only achieves precise and uniform vertical positioning, but also can be applied to different materials within a certain size range, making it highly versatile.

[0016] 2. Effectively eliminates material rebound, ensuring lateral positioning accuracy. While performing vertical positioning, the output shaft of the lateral cylinder assembly pushes the material laterally. Since the material has a certain elasticity, it may rebound when the speed is too fast and it is blocked by the stop bar. Therefore, by continuing to push the material back a fixed distance through the cylinder, the material can be fixed in a uniform position regardless of whether it rebounds, thus achieving precise lateral positioning.

[0017] 3. The conveyor belt is equipped with two gaps and corresponding stop bars. The two stop bars are connected to the same transverse cylinder through the connecting plate, so that the material is subjected to uniform transverse force, avoiding deviation or tilting caused by unilateral force, ensuring that the transverse positioning benchmark of all materials is consistent, and improving the success rate of downstream material picking mechanism.

[0018] 4. The adjustment plate can be adjusted along the direction perpendicular to the material conveying direction (vertical), which can further adjust the installation position of the vertical cylinder, adapt to a wider range of materials, and reduce the equipment adjustment cost when switching between different specifications of materials.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] like Figures 1 to 4As shown, a material alignment conveying module includes a machine base 1, on which a conveying module 2 is mounted, extending along the length of the machine base 1. In this embodiment, the conveying module 2 employs a transmission system including a conveying motor 201, a conveying belt 202, and a synchronous belt 203. The conveying belt 202 is wound around a roller shaft, and the output shaft of the conveying motor 201 drives the roller shaft to rotate via the synchronous belt 203, thereby driving the conveying belt 202 to run. When material 9 is placed on the conveying module 2, it can be conveyed from the first end to the last end of the conveying module 2.

[0023] Vertical cylinder assemblies 3 are respectively installed on both sides of the machine base 1 along the conveying direction of material 9. When material 9 is conveyed to the position, the output shafts of the two vertical cylinder assemblies 3 extend inward along the conveying direction of material 9 and fit against the side walls of material 9, thereby vertically positioning material 9. The two vertical cylinder assemblies 3 are symmetrically arranged at both ends of the width of the machine base 1. Each vertical cylinder assembly 3 includes a mounting plate 303, an adjusting plate 304, a vertical cylinder 301, and a push plate 302. The mounting plate 303 is fixed on the machine base 1. The adjusting plate 304 is adjustablely mounted on the mounting plate 303 along the conveying direction perpendicular to material 9. The vertical cylinder 301 is then fixed on the adjusting plate 304. By adjusting the position of the adjusting plate 304 on the mounting plate 303, the vertical cylinder 301 can be finely adjusted along the width of the machine base 1 to accommodate a wider range of material 9 sizes and reduce the equipment adjustment cost when switching between different specifications of material 9.

[0024] A stepped hole 8 is formed through the adjusting plate 304, extending along the width of the machine base 1. Multiple threaded grooves 7 are formed on the mounting plate 303, arranged along the width of the machine base 1. Bolts are passed through the stepped hole 8 and tightened into the threaded grooves 7 to fix the adjusting plate 304 to the mounting plate 303. Adjustment of the position of the adjusting plate 304 is achieved by installing bolts into different threaded grooves 7. Furthermore, a fixing plate is mounted on the machine base 1. The mounting plate 303 also has a stepped hole 8 and multiple threaded grooves 7, allowing the mounting plate 303 to be adjusted along the width of the machine base 1 in the same manner, further increasing the adjustment range.

[0025] The push plate 302 is fixed to the end of the output shaft of the vertical cylinder 301. The push plate 302 extends along the conveying direction of the material 9, i.e., the length direction of the machine platform 1. The push plate 302 increases the contact area with the material 9, thereby improving the stability during pushing. The two ends of the push plate 302 in the length direction are inclined outward, i.e., inclined away from the material 9, forming a flared opening. Even if the initial position of the material 9 is offset during the conveying process, it can be smoothly guided into the positioning area of ​​the push plate 302 through the inclined ends, avoiding jamming.

[0026] A transverse cylinder assembly 4 is installed near the tail end of the machine 1. The output axis of the transverse cylinder assembly 4 extends in the opposite direction to the material 9 being conveyed, thereby providing transverse positioning for the material 9. The conveyor belt 202 has a gap 6 that extends along the conveying direction of the material 9. The transverse cylinder 401 module includes a transverse cylinder 401 installed at the bottom of the conveying module 2. A stop rod 403 is connected to the output shaft of the transverse cylinder 401. The stop rod 403 extends above the gap 6 to push the material 9. The transverse cylinder 401 drives the stop rod 403 to move along the length of the gap 6. By installing the transverse cylinder 401 at the bottom of the conveying module 2, interference with the movement of the material 9 is avoided.

[0027] In this embodiment, the conveyor belt 202 has two gaps 6. Specifically, three sets of conveyor belts 202 are separately mounted on the roller shaft, thus forming two gaps 6 at the adjacent positions of the three sets of conveyor belts 202. The two gaps 6 are arranged along the width direction of the conveyor belts 202, and a stop bar 403 is respectively arranged in the two gaps 6. A connecting plate 402 is fixed on the output shaft of the transverse cylinder 401, and both stop bars 403 are fixed on the connecting plate 402. The two stop bars 403 are moved synchronously by the transverse cylinder 401 driving the belt 203. By pushing the material 9 simultaneously by the two stop bars 403, the transverse force on the material 9 is uniform, avoiding the deviation or tilt caused by the force on one side, ensuring that the transverse positioning reference of all materials 9 is uniform, and improving the success rate of the downstream material picking mechanism.

[0028] A position sensor 5, electrically connected to the conveying module 2, is installed on the machine base 1. Position sensor 5 is located between the vertical cylinder 301 and the horizontal cylinder 401 along the material 9 conveying direction. When position sensor 5 senses material 9, it controls the conveying module 2 to stop conveying. Position sensor 5 is installed above the table surface of machine base 1 and is an infrared photoelectric sensor, characterized by fast response speed and high sensing accuracy. When material 9 is conveyed to the preset position, the laser beam of position sensor 5 is blocked, and position sensor 5 sends a signal to stop the conveyor motor 201 from driving.

[0029] The workflow for this implementation is as follows: Material 9 is placed on conveying module 2, and conveyor belt 202 conveys material 9 to the tail end. When position sensor 5 detects material 9, it controls conveying module 2 to stop conveying. At this time, the output axis of vertical cylinders 301 on both sides extends out of material 9, and push plate 302 abuts against both sides of material 9. Since the stroke of vertical cylinder 301 is a fixed value, material 9 is vertically positioned in a uniform position. At the same time, material 9 is blocked by the stop bar 403 at the end of conveyor belt 202, and horizontal cylinder 401 pushes material 9 in the opposite direction of conveying. Since the stroke of horizontal cylinder 401 is a fixed value, material 9 is also horizontally positioned in a uniform position, achieving precise positioning in the plane, which facilitates the gripping of the downstream material handling mechanism.

[0030] This embodiment also proposes a material alignment and positioning method, which includes the above-mentioned material alignment and conveying module, and further includes the following steps: S1: The conveying module transports materials from the beginning to the end. When the materials are transported to the preset position, the conveying module stops transporting. S2: The output shafts of the vertical cylinder assemblies on both sides extend inward by a fixed length, and the output shafts push the material for vertical positioning; S3: The output shaft of the transverse cylinder assembly extends a fixed length synchronously in the opposite direction to the material conveying, and the output shaft pushes the material for transverse positioning. Steps S3 and S2 can be performed simultaneously.

[0031] Specifically, by installing a position sensor on the machine, in step S1, when the position sensor senses material, the conveying module stops conveying.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components.
