Description

Technical Field

[0001] This invention relates to the field of conveying technology, and more specifically, to a method for conveying bar stock with deflection correction. Background Technology

[0002] On the factory production line, materials often need to be transported over short distances between processes. In the factory, short-distance transport of bar stock is generally carried out by manual handling or chain drive. If there are many bar stock and manual handling is slow, chain drive is required. The bar stock is placed on the chain, and the bar stock is moved by the meshing of the sprocket and the chain.

[0003] Currently, existing bar stock conveying devices still have some shortcomings. For example, existing bar stock conveying lines cannot adjust the direction of bar stock conveying, which requires manual adjustment of the conveying direction. If manual adjustment is not possible in time, it will affect the subsequent bar stock processing procedures, thereby not only reducing the efficiency of bar stock conveying, but also failing to guarantee the quality of subsequent bar stock processing, thus affecting bar stock processing production.

[0004] In addition, the issue of bar collision must be considered when adjusting the direction of bar transport, especially for some bars with magnetic end faces. Preventing end face collision is one of the issues that needs to be considered when turning and transporting them. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a bar stock turning and correction conveying method. This bar stock turning and correction conveying method can straighten and convey the bar stock, and finally realize the uniform direction of bar stock conveying, so as to eliminate the need for manual adjustment of the conveying direction, thereby improving the efficiency of bar stock conveying and enabling the bar stock to be connected to the next processing step.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a bar stock turning and correction conveying method, characterized in that: a turning conveying mechanism is used to grade and turn the incoming bar stock and convey it to a lifting conveying mechanism to achieve the first turning and correction of the bar stock; the turning conveying mechanism is inclined downward toward the lifting conveying mechanism; a stepped lifting conveying mechanism is used to screen and lift the bar stock; the lifted bar stock is corrected and turned to achieve the second turning and correction of the bar stock, so that the bar stock is finally conveyed to the next processing step in a unified direction.

[0007] In the above scheme, the method of the present invention performs two material handling, turning and correcting operations on the bar stock and then conveys it, so that the bar stock is conveyed to the next processing step in a unified direction. This eliminates the need for manual adjustment of the conveying direction, thereby improving the efficiency of bar stock conveying and allowing the bar stock to be connected to the next processing step according to the conveying direction requirements of the next processing step.

[0008] Using a turning conveyor mechanism to grade, sort, and turn the bar stock into a lifting conveyor mechanism means: an obstruction bar is inclinedly installed above the conveyor line of the turning conveyor mechanism, opposite to the feed inlet; several elastic obstruction plates are inclinedly installed along the conveying direction of the turning conveyor mechanism. These elastic obstruction plates can grade and turn the bar stock into the lifting conveyor mechanism, realizing the first turning and correction of the bar stock.

[0009] The blocking bar can deflect the bar stock fed from the conveyor. During the conveyor line's transport of the bar stock, several elastic blocking plates also deflect and guide the bar stock, transporting it to the lifting conveyor mechanism. After passing through the blocking bar, the inclined conveyor line of the deflecting conveyor mechanism, and the deflection of the elastic blocking plates, the bar stock transported to the lifting conveyor mechanism is mostly placed horizontally with respect to the conveyor line's transport direction, facilitating subsequent lifting and transport. The first deflection correction of this invention can realize the deflection adjustment and transport of the bar stock, solving the problem of low efficiency caused by manual operation, thereby improving the efficiency and quality of bar stock transport.

[0010] Along the conveying direction of the conveyor line, several elastic blocking plates are arranged in a gradually increasing length.

[0011] The elastic blocking plate at the end of the conveyor line in the conveying direction crosses the conveyor line; the elastic blocking plate at the front end of the conveyor line in the conveying direction is an arc-shaped elastic blocking plate; the elastic blocking plates in the middle are arranged in parallel; wherein, the elastic blocking plate in the middle refers to the elastic blocking plate between the elastic blocking plate at the end of the conveyor line in the conveying direction and the elastic blocking plate at the front end of the conveyor line in the conveying direction.

[0012] A reverse conveying chain, opposite to the conveying direction of the main conveyor line, is also installed on the turning conveyor mechanism to turn the bar stock and prevent it from accumulating at the inlet of the lifting conveyor mechanism. The reverse conveying chain not only turns the bar stock but also prevents it from accumulating and blocking the inlet of the lifting conveyor mechanism.

[0013] There is a height difference between the feed inlet and the turning conveyor. This height difference allows the bar stock to smoothly enter the conveyor line by its own weight, or to change the bar stock from an upright position to a horizontal position.

[0014] The step-type lifting and conveying mechanism for screening and conveying bar stock refers to the following: the lifting and conveying mechanism is inclined, and several triangular, square, or polygonal lifting and conveying rollers are arranged on the lifting and conveying mechanism to form a step-type structure. The step-type structure formed by the lifting and conveying rollers screens and lifts bar stock placed perpendicular to the conveying direction of the lifting and conveying rollers. Bar stock placed horizontally to the conveying direction of the lifting and conveying rollers is screened and falls to the turning conveying mechanism for a first turning and correction. The lifting and conveying mechanism of this invention can play a screening role, which is equivalent to a pre-processing of the bar stock for a second turning and correction.

[0015] Corrective conveying of the lifted bar stock, achieving a second correction, involves setting up a corrective conveyor mechanism that interfaces with the lifting conveyor. The lifting conveyor and the corrective conveyor have a height difference. The corrective conveyor mechanism corrects and conveys the bar stock falling from the lifting conveyor, achieving a second correction. The height difference design allows the bar stock to smoothly enter the corrective conveyor mechanism by its own weight, or to change direction.

[0016] The corrective conveying mechanism is equipped with a corrective conveying chain for conveying bar stock; both sides of the corrective conveying chain are provided with blocking parts for blocking the bar stock. When the bar stock falls from the highest point of the lifting conveying mechanism into the corrective conveying mechanism, the blocking parts can block the bar stock, so that the bar stock is positioned on the corrective conveying chain.

[0017] The bar stock is a hollow magnetic bar stock; during the process of conveying the bar stock to the next processing step in the final unified direction, a demagnetizer is set up to demagnetize the bar stock conveyed through the demagnetizer.

[0018] The conveying principle of this invention is as follows: the bar stock fed into the conveyor falls into the steering conveyor mechanism by its own weight. A blocking bar, inclined above the conveyor line and opposite to the feed inlet, blocks the bar stock. During bar stock conveying, the length of the elastic blocking plates arranged along the conveyor line gradually increases, and the inclined arrangement of the elastic blocking plates achieves the effect of grading and steering the bar stock, realizing the first steering and correction of the bar stock. Furthermore, the steering conveyor mechanism is inclined downwards towards the lifting conveyor mechanism, allowing the bar stock to quickly enter the lifting conveyor mechanism after grading and steering. In addition, the inclined arrangement of the elastic blocking plates effectively prevents collisions between the elastic blocking plates and the end faces of the bar stock, thus protecting the end faces of the bar stock. Simultaneously, a reverse conveying chain, opposite to the conveyor line's direction, is added to further steering the bar stock and prevents bar stock from accumulating and blocking the inlet of the lifting conveyor mechanism.

[0019] When the bar stock enters the lifting conveyor mechanism, the stepped structure formed by the lifting conveyor rollers screens and lifts the bar stock placed perpendicular to the conveying direction of the lifting conveyor rollers. Bar stock placed horizontally to the conveying direction of the lifting conveyor rollers is screened and falls to the turning conveyor mechanism for the first turning and correction. When the bar stock falls from the highest point of the lifting conveyor mechanism into the correcting conveyor mechanism, the blocking part blocks the bar stock, ensuring it is positioned on the correcting conveyor chain. The correcting conveyor mechanism turns and conveys the bar stock falling from the lifting conveyor mechanism, achieving a second turning and correction. Finally, during the process of conveying the bar stock in the final unified direction to the next processing step, a demagnetizer is installed to demagnetize the bar stock that has passed through the demagnetizer and buffer it before entering the centerless mill for external cylindrical grinding.

[0020] Compared with the prior art, the present invention has the following advantages and beneficial effects: the bar stock turning and correction conveying method of the present invention can turn and convey the bar stock, and finally realize the uniform direction of bar stock conveying, so as to eliminate the need for manual adjustment of the conveying direction, thereby improving the efficiency of bar stock conveying and enabling the bar stock to be connected to the next processing step.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figures 1 to 6 As shown, the bar stock steering and correction conveying method of the present invention uses a steering and correction conveying device comprising a feeding conveying mechanism 1, a steering conveying mechanism 2, a lifting conveying mechanism 3, and a correction conveying mechanism 4 connected in sequence. The steering conveying mechanism 2 is inclined downward toward the lifting conveying mechanism 3, and there is a height difference between the feeding conveying mechanism 1 and the steering conveying mechanism 2, and between the lifting conveying mechanism 3 and the correction conveying mechanism 4.

[0032] The steering conveying mechanism 2 of the present invention includes a steering conveying frame 2.1, a conveying component for conveying the bar stock 6, and a steering component for steering the bar stock 6. The conveying component is disposed on the steering conveying frame 2.1 and is respectively connected to the feeding conveying mechanism 1 and the lifting conveying mechanism 3.

[0033] Specifically, the steering assembly includes a blocking rod 2.2 and several elastic blocking plates 2.3. The blocking rod 2.2 is obliquely disposed on the steering conveyor frame 2.1, and is located above the conveying assembly and opposite to the feeding conveying mechanism 1. Several elastic blocking plates 2.3 are disposed on the steering conveyor frame 2.1 along the conveying direction of the conveying assembly and are located above the conveying assembly. The elastic blocking plates 2.3 at the end along the conveying direction of the conveying assembly are located above the conveying assembly opposite to the lifting conveying mechanism 3.

[0034] The conveying assembly includes a conveying drive component 2.4, a conveying transmission component (not shown), and several conveying plates 2.5. The conveying drive component 2.4 is mounted on the steering conveyor frame 2.1. The conveying drive component 2.4 is connected to several conveying plates 2.5 through the conveying transmission component to drive the movement of several conveying plates 2.5.

[0035] Several elastic blocking plates 2.3 of the present invention are respectively inclinedly arranged on the turning conveyor frame 2.1. Along the conveying direction of the conveyor plate 2.5, the elastic blocking plates 2.3 are arranged in a gradually increasing length. The elastic blocking plates 2.3 at the end of the conveying direction of the conveyor plate 2.5 span the conveyor plate 2.5. The end elastic blocking plates 2.3 can serve as the final turning component, allowing the bar stock 6, which has not been turned by the preceding elastic blocking plates 2.3 and is conveyed to the lifting conveyor 3, to be finally turned by the end elastic blocking plates 2.3. Simultaneously, the inclination angle between the end elastic blocking plates 2.3 and the conveying direction of the conveyor plate 2.5 is 100°. The elastic blocking piece 2.3 at the front end of the conveying direction of the conveyor plate 2.5 is an arc-shaped elastic blocking piece. The inclination angle between the middle elastic blocking piece 2.3 and the conveying direction of the conveyor plate 2.5 is 120°. The middle elastic blocking piece 2.3 refers to the elastic blocking piece 2.3 between the elastic blocking piece 2.3 at the end of the conveying direction of the conveyor plate 2.5 and the elastic blocking piece 2.3 at the front end of the conveying direction of the conveyor plate 2.5.

[0036] In order to improve the efficiency of the bar stock 6 turning and conveying, the turning conveyor frame 2.1 is inclined downward toward the lifting conveyor 3, and there is a height difference of 10-20 mm between the feeding conveyor 1 and the turning conveyor frame 2.1, which allows the bar stock 6 to smoothly enter the conveyor plate 2.5 by its own weight, or change from a vertical position to a horizontal position.

[0037] The conveying assembly also includes a reverse conveying assembly, which comprises a reverse conveying drive component 2.6 and a reverse conveying chain 2.7. The reverse conveying drive component 2.6 is mounted on the steering conveyor frame 2.1 and connected to the reverse conveying chain 2.7, thereby driving the reverse conveying chain 2.7 to move. The conveying direction of the reverse conveying chain 2.7 is opposite to the conveying direction of the conveying plate 2.5. The reverse conveying chain 2.7 of this invention not only serves to deflect the bar stock 6 but also prevents the bar stock 6 from accumulating and blocking between the lifting conveying mechanism 3 and the conveying plate 2.5.

[0038] The lifting and conveying mechanism 3 of the present invention includes a lifting and conveying frame 3.1 and a lifting and conveying assembly, wherein the lifting and conveying frame 3.1 is inclined. The lifting and conveying assembly includes a lifting and conveying drive component 3.2, a lifting and conveying transmission component 3.4, and a plurality of square lifting and conveying rollers 3.3. The lifting and conveying drive component 3.2 is mounted on the lifting and conveying frame 3.1, and is connected to the plurality of lifting and conveying rollers 3.3 through the lifting and conveying transmission component 3.4, thereby driving the plurality of lifting and conveying rollers 3.3 to rotate. This connection method of the lifting and conveying drive component 3.2 to the plurality of lifting and conveying rollers 3.3 through the lifting and conveying transmission component 3.4 is a common mechanical connection method.

[0039] Several lifting conveyor rollers 3.3 are arranged on an inclined lifting conveyor frame 3.1, forming a stepped structure. The square lifting conveyor rollers 3.3 allow for the lifting and conveying of bar stock 6 placed perpendicular to the conveying direction of the lifting conveyor rollers 3.3, while bar stock 6 placed horizontally to the conveying direction of the lifting conveyor rollers 3.3 will slip and cannot be lifted and conveyed. This allows the subsequent corrective conveying assembly to redirect and correct the bar stock 6 placed perpendicular to the conveying direction of the lifting conveyor rollers 3.3 to a uniform conveying direction. Therefore, this design can pre-process bar stock 6 that does not have a uniform conveying direction.

[0040] The corrective conveying mechanism 4 includes a corrective conveyor frame 4.1 and a corrective conveying assembly. The corrective conveyor frame 4.1 is provided with a blocking part 4.2 for blocking the bar stock 6. The corrective conveying assembly includes a corrective conveying drive component 4.3 and a corrective conveying chain 4.4. The corrective conveying drive component 4.3 is mounted on the corrective conveyor frame 4.1 and connected to the corrective conveying chain 4.4 to drive the movement of the corrective conveying chain 4.4, which is located between the blocking parts 4.2 on both sides of the corrective conveyor frame 4.1. The height difference between the highest point of the lifting conveyor assembly and the corrective conveying assembly is 10-20 mm. The corrective conveying chain 4.4 not only conveys the bar stock 6 but also corrects its direction. When the bar stock 6 falls from the highest point of the lifting conveyor assembly into the corrective conveying assembly, the blocking part 4.2 blocks the bar stock 6, ensuring that the bar stock 6 is positioned within the corrective conveying assembly. The height difference design allows the bar stock 6 to smoothly enter the corrective conveying assembly by its own weight or change direction.

[0041] In this embodiment, the bar stock 6 is an automotive pin, i.e., a magnetic bar stock. The steering and correction conveying device also includes a demagnetizer 5, which is disposed on the correction conveying assembly. The bar stock 6, which is corrected by the correction conveying assembly, is placed horizontally with the conveying direction of the correction conveying chain 4.4. After being demagnetized by the demagnetizer 5, the bar stock 6 can enter the next processing step through the correction conveying chain 4.4, such as entering a grinding machine for external cylindrical grinding of the bar stock 6.

[0042] The bar stock turning and correction conveying method of the present invention is as follows: the turning conveying mechanism 2 is used to classify and turn the feed bar stock 6 and convey it to the lifting conveying mechanism 3 to realize the first turning and correction of the bar stock 6. The turning conveying mechanism 2 is inclined downward toward the lifting conveying mechanism 3. The lifting conveying mechanism 3 with a stepped structure is used to screen and lift the bar stock 6. The lifted bar stock 6 is corrected and turned to achieve the second turning and correction of the bar stock 6, so that the bar stock 6 is finally conveyed to the next processing step in a unified direction.

[0043] Specifically, a blocking rod 2.2 is inclinedly arranged above the conveyor plate 2.5 of the turning conveyor mechanism 2, opposite to the inlet of the feeding conveyor mechanism 1; along the conveying direction of the turning conveyor mechanism 2, several elastic blocking plates 2.3 are inclinedly arranged on the conveyor plate 2.5. These elastic blocking plates 2.3 can grade and turn the conveyed bar stock 6 to the lifting conveyor mechanism 3, realizing the first turning and correction of the bar stock 6. Among them, along the conveying direction of the conveyor plate 2.5, the elastic blocking plates 2.3 are arranged in a gradually increasing length. The elastic blocking plates 2.3 at the end of the conveying direction of the conveyor line span the conveyor plate 2.5; the elastic blocking plates 2.3 at the front end of the conveying direction of the conveyor plate 2.5 are arc-shaped elastic blocking plates; the elastic blocking plates 2.3 in the middle are arranged in parallel.

[0044] The method of this invention further includes a reverse conveying chain 2.7 on the turning conveying mechanism 2, which is opposite to the conveying direction of the conveying line. This enables the bar stock 6 to be turned and prevents it from accumulating at the inlet of the lifting conveying mechanism 3. There is a height difference between the inlet of the feeding conveying mechanism 1 and the turning conveying mechanism 2. This height difference allows the bar stock 6 to smoothly enter the conveying plate 2.5 by its own weight, or to change the bar stock 6 from an upright position to a horizontal position.

[0045] In the method of this invention, the use of a stepped lifting and conveying mechanism 3 to screen and lift the bar stock 6 refers to the following: the lifting and conveying mechanism 3 is inclined, and several triangular, square, or polygonal lifting and conveying rollers 3.3 are arranged on the lifting and conveying mechanism 3 to form a stepped structure; the stepped structure formed by the lifting and conveying rollers 3.3 screens and lifts the bar stock 6 placed perpendicular to the conveying direction of the lifting and conveying rollers 3.3, while the bar stock 6 placed horizontally to the conveying direction of the lifting and conveying rollers 3.3 is screened and falls to the turning conveying mechanism 2 for the first turning and correction. The lifting and conveying mechanism 3 of this invention can act as a screening mechanism, equivalent to pre-processing the bar stock 6 for the second turning and correction.

[0046] The second correction and repositioning of the lifted bar stock 6 involves setting up a correction conveyor 4 that connects to the lifting conveyor 3. The lifting conveyor 3 and the correction conveyor 4 have a height difference. The correction conveyor 4 repositions and repositions the bar stock 6 as it falls from the lifting conveyor 3, thus achieving the second correction. During the final unified conveying of the bar stock 6 to the next processing step, a demagnetizer 5 is installed to demagnetize the bar stock 6 as it passes through it.

[0047] The conveying principle of this invention is as follows: the bar stock 6, fed by its own weight, falls into the turning conveyor mechanism 2. A blocking rod 2.2, inclined above the conveying plate 2.5 of the turning conveyor mechanism 2 and opposite to the inlet of the feeding conveyor mechanism 1, blocks the bar stock 6. During the conveying process of the bar stock 6, the length of the elastic blocking plates 2.3, arranged along the conveying direction of the conveying plate 2.5, gradually increases, and the inclined arrangement of the elastic blocking plates 2.3 achieves the effect of graded turning and material handling of the bar stock 6, realizing the first turning and correction of the bar stock 6. Furthermore, the turning conveyor mechanism 2 is inclined downwards towards the lifting conveyor mechanism 3, allowing the bar stock 6 to quickly enter the lifting conveyor mechanism 3 after graded turning and material handling. In addition, the inclined arrangement of the elastic blocking plates 2.3 effectively prevents collision between the elastic blocking plates 2.3 and the end faces of the bar stock 6, thus protecting the end faces of the bar stock 6. At the same time, a reverse conveying chain 2.7, which is opposite to the conveying direction of the conveying plate 2.5, is added to further deflect the bar stock 6 and also prevent the bar stock 6 from accumulating and blocking the inlet of the lifting conveying mechanism 3.

[0048] When the bar stock 6 enters the lifting conveyor mechanism 3, the stepped structure formed by the lifting conveyor rollers 3.3 screens and lifts the bar stock 6 that is placed perpendicular to the conveying direction of the lifting conveyor rollers 3.3. The bar stock 6 that is placed horizontally to the conveying direction of the lifting conveyor rollers 3.3 is screened and falls to the turning conveyor mechanism 2 for the first turning correction. When the bar stock 6 falls from the highest point of the lifting conveyor mechanism 3 into the correcting conveyor mechanism 4, the blocking part 4.2 can block the bar stock 6, so that the bar stock 6 is located on the correcting conveyor chain 4.4. The correcting conveyor mechanism 4 turns and conveys the bar stock 6 that has fallen from the lifting conveyor mechanism 3, realizing the second turning correction of the bar stock 6. Finally, during the process of the bar stock 6 being conveyed to the next processing step in the final unified direction, a demagnetizer 5 is set up to demagnetize the bar stock 6 that has been conveyed through the demagnetizer 5 and buffer it before entering the centerless mill for external cylindrical grinding.

[0049] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
