Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and in particular to a conveying device for the production of sports goods. Background Art

[0002] During the production and processing of sports goods, it is often necessary to convey the produced sports goods for further processing or packaging.

[0003] However, when traditional conveying devices convey sports goods, there are often problems such as low conveying efficiency and poor stability, resulting in easy damage to sports goods during the conveying process, which affects the production efficiency and quality of sports goods.

[0004] Therefore, during the production process, it is necessary to conduct a comprehensive inspection of sports goods. Since most inspections on the market rely on manual inspection, during the inspection process, the conveying device is still operating, and it is impossible to briefly intercept the sports goods to be inspected, resulting in the inability of operators to inspect all sports goods.

[0005] With the goal of improving the safety of conveying and the quality of products, we propose a conveying device for the production of sports goods. Summary of the Invention

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1 to 8 , the present invention provides a technical solution:

[0041] A conveying device for the production of sports goods, including a conveying frame 1, and groove rods 2 are horizontally and symmetrically fixedly installed at the top of the conveying frame 1. A chain 3 is rotatably installed inside the groove rod 2. Among them, the chain 3 is a tensioning device, which can avoid the situation of insufficient wrap angle when meshing with the rear gear 5, as Figure 2 and Figure 3 shown.

[0042] Then, gears 5 are rotatably installed evenly on the horizontal line inside the groove rod 2. The gears 5 are meshed with the chain 3. Moreover, a conveying roller 4 is fixedly installed between two adjacent front and rear gears 5. The gear 5 at the left rear end is fixedly connected to the output shaft of the first motor 6 on the outer side of the groove rod 2, as Figure 1 shown.

[0043] During the use process, start the first motor 6. The output shaft of the first motor 6 will drive the fixedly connected gear 5 to rotate. During the rotation of the gear 5, it will drive the fixedly connected conveying roller 4 to rotate synchronously. The conveying roller 4 will drive the front gear 5 to rotate. Therefore, under the action of the gear 5, the two front and rear chains 3 can be driven to rotate synchronously. During the rotation of the chain 3, it will drive the remaining gears 5 to rotate, so that all the gears 5 can drive the fixedly connected conveying rollers 4 to rotate synchronously, and then the sports goods can be conveyed from the right side to the left side, as Figure 1 shown.

[0044] Then, a first discharge rack 9 and a second discharge rack 10 are arranged on the left side of the conveying frame 1. Among them, the first discharge rack 9 is located at the rear end of the second discharge rack 10, as Figure 1 shown.

[0045] During the use process, when the sports goods pass through the U-shaped frame 25, the subsequent second limiting plate 34 and the second roller 35 will adjust their positions according to the photos taken by the first vision camera 22 and the second vision camera 28 symmetrically arranged up and down on the left side, so as to correspond the movement path of the passing sports goods to the first discharge rack 9 and the second discharge rack 10 on the left side, so that the sports goods can enter the first discharge rack 9 or the second discharge rack 10, so as to change the movement paths of different sports goods, and then the sports goods can be shunted, so as to help the operators save the sorting time of the products.

[0046] It should be noted that corresponding conveyor belts are arranged inside the first discharge rack 9 and the second discharge rack 10, so that the sports goods can be conveyed to fixed positions.

[0047] Secondly, a main telescopic pump 7 is fixedly installed on the inner ground of the conveying rack 1, and a feeding plate 8 is fixedly installed on the telescopic rod of the main telescopic pump 7, as Figure 2 shown.

[0048] During the use process, the main telescopic pump 7 is started. The telescopic rod of the main telescopic pump 7 will drive the feeding plate 8 to move up and down. During the upward movement process, the sports goods passing through will be lifted upward, so that the upward moving sports goods can enter the interiors of the two U-shaped racks 25 that are symmetric left and right, as Figure 1 shown.

[0049] Then, first L-shaped rods 11 are fixedly installed on the outer side surfaces of the right parts of the front and rear groove rods 2. First U-shaped plates 12 are fixedly installed on the inner sides of the upper parts of the first L-shaped rods 11. A first rotating rod 13 is rotatably installed inside the first U-shaped plate 12. Among them, the inner end of the first rotating rod 13 far from the first U-shaped plate 12 is rotatably installed with a second rotating rod 14, and the outer end of the second rotating rod 14 far from the first rotating rod 13 is rotatably installed with a second U-shaped plate 15. Among them, a first limiting plate 18 is fixedly installed on the common inner side surfaces of the two second U-shaped plates 15 in the horizontal direction, as Figure 5 shown.

[0050] The first limiting plate 18 is in an L-shaped structure. And, a row of first rollers 19 are rotatably installed horizontally and evenly on the inner upper part of the first limiting plate 18, as Figure 5 shown.

[0051] Secondly, second motors 16 are fixedly installed on the outer side surfaces of the upper parts of the two second U-shaped plates 15 in the horizontal direction. First reciprocating lead screws 17 are fixedly installed on the output shafts of the second motors 16. The far ends of the first reciprocating lead screws 17 are threadedly rotatably connected to the upper parts of the first U-shaped plates 12, as Figure 5 shown.

[0052] During the use process, when the conveying roller 4 conveys the sports goods from the right side to the left side, at this time, according to the situation, the second motor 16 can be started. The output shaft of the second motor 16 drives the first reciprocating lead screw 17 to rotate. When the first reciprocating lead screw 17 rotates, the second U-shaped plate 15 will gradually move away from the first U-shaped plate 12. At this time, the second U-shaped plate 15 will drive the first rotating rod 13 and the second rotating rod 14 to rotate, so as to change the included angle between the two. Then, after the included angle between the first rotating rod 13 and the second rotating rod 14 becomes smaller, the two front and rear first limiting plates 18 will gradually approach, so that the first rollers 19 can gradually approach, and further the sports goods on the circumferential surface of the conveying roller 4 can be restricted to the central position on the circumferential surface of the conveying roller 4, and further it can be ensured that during the subsequent operation, the sports goods can be in a state of being in contact with the feeding plate 8.

[0053] It should be noted that the feeding plate 8 is located between two adjacent conveying rollers 4, which will not affect the conveying rollers 4 and there will be no collision.

[0054] Then, the second motor 16 can be adjusted according to the size of the sports goods, so as to change the distance between the two front and rear first limiting plates 18.

[0055] Then, horizontally symmetric first telescopic pumps 20 are fixedly installed on the lower end surfaces of the front and rear groove rods 2. A fixed connecting plate 21 is fixedly installed on the telescopic rods of the two front and rear first telescopic pumps 20. First vision cameras 22 are fixedly installed on the outer side surfaces of the fixed connecting plate 21, as Figure 6 shown.

[0056] Among them, the right first vision camera 22 is used to take pictures of the product to determine whether there is a quality problem with the product, while the left first vision camera 22 is used to determine which discharge rack the product needs to move to during subsequent conveying.

[0057] It should be noted that during use, the first telescopic pump 20 can be started according to the situation, so as to change the height of the first vision camera 22 to cope with different situations.

[0058] Then, horizontally symmetric second telescopic pumps 23 are fixedly installed on the upper end surfaces of the front and rear groove rods 2. A support plate 24 is fixedly installed on the telescopic rods of the two front and rear second telescopic pumps 23. The upper end surface of the support plate 24 is fixedly connected to the lower end surface of the adjacent U-shaped frame 25, as Figure 6 shown.

[0059] Second vision cameras 28 are fixedly installed on the outer side surfaces of the left and right U-shaped frames 25. The right second vision camera 28 takes pictures of the product quality, and the left second vision camera 28 determines which discharge rack the product will move to during subsequent conveying.

[0060] Then, support rods 26 are vertically and evenly rotatably installed inside the U-shaped frame 25. Secondly, a limiting rod 27 is fixedly installed on the upper part of the outer end of the support rod 26 on the inner side of the U-shaped frame 25 far from the opening, as Figure 7 shown.

[0061] During the use process, the feeding plate 8 conveys the sports products upwards. At this time, the sports products will cause the support rod 26 to rotate. When the sports products pass over the support rod 26, the support rod 26 will reset itself. At this time, under the restriction of the limit rod 27, the support rod 26 is reset to a horizontal state. At this time, the main telescopic pump 7 drives the feeding plate 8 to move downwards, so that the sports products can be placed on the upper end surfaces of two adjacent support rods 26 on the left and right. By analogy, the interception operation of multiple sports products can be completed.

[0062] On the outer side surfaces of the left parts of the groove rods 2, second L-shaped rods 29 are fixedly installed. On the inner sides of the upper parts of the second L-shaped rods 29, third U-shaped plates 30 are fixedly installed. Inside the third U-shaped plates 30, third rotating rods 31 are rotatably installed. Inside one end of the third rotating rod 31 away from the third U-shaped plate 30, a fourth rotating rod 32 is rotatably installed. On the outer side of one end of the fourth rotating rod 32 away from the third rotating rod 31, a fourth U-shaped plate 33 is rotatably installed. On the inner side surfaces of two transverse fourth U-shaped plates 33, a second limiting plate 34 is fixedly installed together. The second limiting plate 34 is in an L-shaped structure. And, on the upper part inside the second limiting plate 34, second rollers 35 are evenly rotatably installed in the transverse direction. The lower ends of the first roller 19 and the second rollers 35 do not contact the conveying rollers 4, so as to avoid collision.

[0063] Then, on the outer side surfaces of the upper parts of the fourth U-shaped plates 33, third motors 36 are fixedly installed. On the output shafts of the third motors 36, second reciprocating lead screws 37 are fixedly installed. One end of the second reciprocating lead screw 37 away from the third motor 36 is in threaded rotational connection with the upper part of the third U-shaped plate 30, as Figure 8 shown.

[0064] During the use process, start the third motor 36. The output shaft of the third motor 36 drives the second reciprocating lead screw 37 to rotate, so that the third motor 36 can move away from or close to the third U-shaped plate 30, so that the third rotating rod 31 and the fourth rotating rod 32 can rotate, thereby changing the included angle between the two, so that the distance between the two transverse second limiting plates 34 can be changed, and then the sports products can be restricted, so that the sports products can be conveyed to the corresponding discharge racks, such as inside the first discharge rack 9 or the second discharge rack 10.

[0065] Because during the use process, the front second limiting plate 34 does not move, and the rear second limiting plate 34 moves forward. At this time, the sports products can be conveyed into the second discharge rack 10. On the contrary, when the front second limiting plate 34 moves backward, the sports products can be conveyed into the first discharge rack 9, so as to complete the diversion of the sports products.

[0066] Working principle: First, place the sports goods on the circumferential surface of the conveying roller 4, start the first motor 6, the output shaft of the first motor 6 drives the gear 5 to rotate, the gear 5 drives the conveying roller 4 to rotate, the conveying roller 4 drives the front-end gear 5 to rotate, the gear 5 drives the chain 3 to rotate, the chain 3 drives the remaining gears 5 to rotate, and the gears 5 drive the remaining conveying rollers 4 to rotate synchronously to convey the sports goods.

[0067] Secondly, start the second motor 16 as required, the second motor 16 drives the first reciprocating lead screw 17 to rotate synchronously, so that the first rotating rod 13 and the second rotating rod 14 rotate, thereby making the first limiting plate 18 approach or move away.

[0068] Then, take pictures and conduct quality inspections on the passing sports goods through the first vision camera 22 on the right and the second vision camera 28 on the right.

[0069] For the products with quality problems, start the main telescopic pump 7, and the main telescopic pump 7 drives the feeding plate 8 to move upward.

[0070] At this time, convey the sports goods upward, so that the sports goods can be placed on the upper end surfaces of the left and right support rods 26 for personnel to inspect.

[0071] For the remaining products, start the third motor 36, the output shaft of the third motor 36 drives the second reciprocating lead screw 37 to rotate synchronously, so that the third rotating rod 31 and the fourth rotating rod 32 rotate, and then make the second limiting plate 34 approach or move away. According to the situation, adjust the second limiting plate 34 at the front end or the rear end, so that the sports products enter the inside of the first discharge rack 9 or the second discharge rack 10. In this way, the diversion and quality inspection operations of the products are completed, and the products with problems are intercepted.

[0072] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
