Description

Technical Field

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

[0002] Dumbbells are a kind of exercise equipment with relatively small size and appropriate weight. They are widely used in home life and some living places. Dumbbells can be roughly divided into two types: one-piece type and split-piece type. When producing split-piece dumbbells, in addition to the production of handles, the production of dumbbell plates is also crucial. In the production process, the dumbbell plates need to be individually bagged and then packaged in combination. When the dumbbell plates are moved from the production part to the packaging area, they need to be transported by corresponding conveying devices to facilitate subsequent packaging work.

[0003] The existing conveying work is mostly done by placing the completed dumbbell pieces on a conveyor table for conveying. After arriving at the packaging area, a dedicated staff member removes the single dumbbell piece and stacks it, and then transports it to the packaging workbench and hands it over to the packaging staff for bagging. Since the dumbbell pieces have a relatively large mass, the staff believe that it is not convenient to remove the dumbbell pieces from the surface of the conveyor belt. There is also a risk of slipping during the transportation after stacking, which may cause injuries to the staff, increasing the risk factor of the entire work. In the subsequent packaging process, the staff is required to take a single dumbbell piece from the stacked dumbbell piece pile for bagging, which is inconvenient to operate and may cause injury to the fingers due to the squeezing of the dumbbell pieces, further increasing the danger during the work process.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 the embodiments.

[0038] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] Reference Figure 1-Figure 12 A finished product conveying device for producing dumbbells, comprising a conveying frame 1, a conveying belt 2 is rotatably connected to the surface of the conveying frame 1, the conveying belt 2 is driven by a motor, a plurality of placing plates 3 are slidably connected to the surface of the conveying belt 2, two connecting frames 4 are slidably connected to the top of the conveying frame 1, a connecting plate 5 is slidably connected to the top of the two connecting frames 4, one end of the conveying frame 1 is fixedly connected to a chassis 6, the top of the chassis 6 is rotatably connected to a receiving frame 7, and further comprising:

[0040] The grabbing mechanism 8 is slidably connected to the top of the conveying frame 1, and the grabbing mechanism 8 is fixedly connected to the connecting frame 4. The grabbing mechanism 8 is used to grab the dumbbell plates. The grabbing mechanism 8 includes a hydraulic cylinder 801, a top cylinder 802, a pressing plate 803 and four bottom claws 804. The hydraulic cylinder 801 is slidably connected to the top of the conveyor belt 2, and the hydraulic cylinder 801 is fixedly sleeved with the connecting plate 5. The output end of the hydraulic cylinder 801 is fixedly connected to the top cylinder 802, and the pressing plate 803 is slidably connected to the inside of the top cylinder 802. The inside of the top cylinder 802 is fixedly connected with a cylinder 13, and the output end of the cylinder 13 is slidably connected to the pressing plate 803. Four push rods 14 are evenly hinged on the surface of the pressing plate 803. Four sliding grooves 15 are opened in the inside of the top cylinder 802. The other end of the push rod 14 penetrates to the bottom of the sliding groove 15 and is hinged to the top of the bottom claw 804. The four bottom claws 804 are slidably connected to the bottom of the top cylinder 802, and the bottom claw 804 is located above the placement plate 3.

[0041] Among them, the conveyor belt 2 is driven by the motor to rotate along the conveyor frame 1. After the dumbbell pieces are placed on the surface of the placement plate 3, they can be stably transported by the conveyor belt 2. The hydraulic cylinder 801 pushes the top cylinder 802 downward, forcing the top cylinder 802 to be inserted into the mounting hole in the middle of the dumbbell piece. At this time, the cylinder 13 works to force the pressing plate 803 to move downward along the inside of the top cylinder 802. At this time, the push rod 14 slides on the top cylinder 802 due to the sliding effect between the slide groove 15, and because the two ends of the push rod 14 are respectively hinged with the inside of the pressing plate 803 and the top of the bottom claw 804, the push rod 14 slides downward with the pressing plate 803 and drives the bottom claw 804 to expand from the bottom of the top cylinder 802 to the surrounding of the top cylinder 802, that is, the bottom claw 804 will be inserted into the gap between the dumbbell piece and the placement plate 3, so that the dumbbell piece is grabbed from the top of the placement plate 3, avoiding workers manually taking the dumbbell piece from the surface of the conveyor belt 2, which is convenient for work and relatively safe.

[0042] The pushing mechanism 9 is arranged inside the conveyor belt 2. The pushing mechanism 9 is used to push the connecting frame 4 to slide. The pushing mechanism 9 includes two support blocks 901 and two push blocks 902. The two support blocks 901 are symmetrically hinged on the top of the placement plate 3, and the two support blocks 901 are both slidably connected to the inside of the conveyor belt 2. The other end of the support block 901 is hinged to the push block 902. The push block 902 is slidably connected to the inside of the conveyor belt 2. The top of the placement plate 3 is fixedly connected with a top spring 16, and the other end of the top spring 16 is fixedly connected to the inside of the conveyor belt 2. The ends of the two push blocks 902 away from the top spring 16 slide through the two sides of the conveyor belt 2 respectively.

[0043] Among them, when the dumbbell plate is placed on the top of the placement plate 3, the dumbbell plate will press down the placement plate 3 by its own weight. At this time, the two support blocks 901 at the bottom of the placement plate 3 will slide inside the conveyor belt 2 and push the two push blocks 902 to slide out of the conveyor belt 2 respectively, and at this time, the top cylinder 802 is in a downward pressing state on the placement plate 3, ensuring that the placement plate 3 will not be lifted up by the top spring 16. After the push block 902 enters the interior of the slide 18, it will contact the side of the connecting column 17. As the conveyor belt 2 slides, the connecting column 17 is driven to slide along the slide 18, forcing the grabbing mechanism 8 to follow the conveyor belt 2 to move in the direction close to the transfer mechanism 12 after grabbing the dumbbell plate, ensuring that the grabbing mechanism 8 can smoothly transport the dumbbell plate.

[0044] Reset mechanism 10, two reset mechanisms 10 are symmetrically arranged inside the conveyor frame 1, and the reset mechanism 10 is used to drive the connecting frame 4 to reset. The reset mechanism 10 includes two rotating wheels 101, a reset toothed belt 102 and a connecting wheel 103. The two rotating wheels 101 on the same side are symmetrically rotated and connected to the inside of the conveyor frame 1. The reset toothed belt 102 is rotatably connected to the inside of the conveyor frame 1 through the two rotating wheels 101, and one of the rotating wheels 101 is fixedly connected to the connecting wheel 103. The connecting wheel 103 can be driven by a motor through a belt, and the rotation direction of the reset toothed belt 102 is opposite to the rotation direction of the conveyor belt 2. The interior of the connecting frame 4 is slidably connected with a connecting column 17, and the two ends of the connecting column 17 are respectively penetrated with the two ends of the connecting frame 4. Slideways 18 are symmetrically arranged on both sides, and reset grooves 19 are symmetrically opened on both sides of the top of the conveying frame 1. The slideways 18 are connected to the reset grooves 19. When the bottom of the connecting column 17 is located inside the slideway 18, it can be pushed by the push block 902. When the bottom of the connecting column 17 is located inside the reset groove 19, it can engage with the reset toothed belt 102. The connecting column 17 passes through one end above the connecting frame 4 and is slidably connected to the bottom of the connecting plate 5. The connecting column 17 is located on both sides of the inner surface of the connecting frame 4 and is symmetrically fixedly connected with two springs 25. The other end of the spring 25 is fixedly connected to the inside of the connecting frame 4. Guide grooves 26 are symmetrically opened on both sides of the surface of the connecting frame 4. A number of guide heads 27 are fixedly connected to the surface of the conveying frame 1, and the guide heads 27 are slidably connected to the connecting frame 4 through the guide grooves 26.

[0045] After the connecting column 17 slides along the slide 18 from one end away from the transfer mechanism 12 to the end close to the transfer mechanism 12, the connecting frame 4 and the connecting plate 5 slide to drive the grabbing mechanism 8 to move to the top of the receiving tray 121. At this time, the output end of the cylinder 13 retracts to force the four bottom claws 804 to retract, and the grabbed dumbbell pieces can be released in the receiving tray 121. At this time, the guide head 27 close to the transfer mechanism 12 will slide with the guide groove 26, forcing the connecting column 17 to enter the reset groove 19 from the slide 18. Because the dumbbell pieces will press down the two connecting pieces through the connecting plate 5 due to their own weight, the connecting plate 5 will press down the two connecting pieces. The connecting column 17 does not mesh with the reset toothed belt 102 when it moves into the reset groove 19. After the grabbing mechanism 8 completely releases the dumbbell plate, the spring 25 pushes the connecting column 17 upward, and the connecting column 17 meshes with the reset toothed belt 102. At this time, the reset toothed belt 102 drives the connecting column 17 and the entire grabbing mechanism 8 to slide along the reset groove 19 in a direction away from the transfer mechanism 12, and at the other end of the reset groove 19, the sliding effect between the guide head 27 and the guide groove 26 forces the connecting column 17 to re-enter the slideway 18 and perform the grabbing work again.

[0046] The transmission mechanism 11 includes a transmission box 111, two transmission wheels 112, a shifting tooth 113 and a bevel gear 114. The transmission box 111 is fixedly connected to one side of the conveyor frame 1, and the other end of the transmission box 111 is fixedly connected to the surface of the chassis 6. The two transmission wheels 112 are symmetrically connected to the inside of the transmission box 111. One of the transmission wheels 112 is fixedly connected to a rotating wheel 101 away from the connecting wheel 103. The two transmission wheels 112 are connected by belt transmission. The other transmission wheel 112 is fixedly connected to the shifting tooth 113, the shifting tooth 113 is meshed with the bevel gear 114, and the shifting tooth 113 and the bevel gear 114 are both rotatably connected to the inside of the chassis 6.

[0047] Among them, the transmission wheel 112 is driven to rotate by the rotating wheel 101. At this time, the transmission effect of the belt can force the two transmission wheels 112 to rotate synchronously in the transmission box 111, which can drive the shifting tooth 113 to rotate. Through the meshing effect between the shifting tooth 113 and the bevel tooth 114, the bevel tooth 114 is forced to rotate in the chassis 6. After the dumbbell pieces are placed in the receiving tray 121 close to the side of the conveyor belt 2, the bevel tooth 114 can drive the entire transfer mechanism 12 to rotate, so as to facilitate the transfer of the dumbbell pieces to the packaging work area and avoid the greater danger when manual handling is used.

[0048] The transfer mechanism 12 includes two receiving trays 121, two top plates 122 and two legs 123. The two receiving trays 121 are symmetrically slidably connected to the two sides of the receiving frame 7. The top plate 122 is hinged to the inside of the receiving tray 121. The top of the leg 123 penetrates to the top of the receiving tray 121 and is hinged to the bottom of the top plate 122. A guide slope 20 is fixedly connected to one side of the top of the chassis 6. The leg 123 is slidably connected to the top of the guide slope 20. The top of the bevel gear 114 is fixedly connected to the sleeve column 21. The top of the sleeve column 21 is connected to the chassis. 6 is rotated through the top, and the interior of the receiving frame 7 is slidably connected with a sleeve 22, and the two sides of the top of the sleeve 22 are respectively fixedly connected to the two receiving plates 121, and the top of the sleeve column 21 is slidably connected to the interior of the sleeve 22, and one end of the sleeve column 21 located inside the sleeve 22 is fixedly connected with a tooth head 23, and the interior of the sleeve 22 is fixedly connected with a gear ring 24, and the tooth head 23 can mesh with the gear ring 24, and the two sides of the bottom of the sleeve 22 are symmetrically fixedly connected with return springs 28, and the other end of the return spring 28 is fixedly connected to the interior of the receiving frame 7.

[0049] Among them, the dumbbell pieces transported by the grabbing mechanism 8 are received by the receiving tray 121 close to one side of the conveyor belt 2, and the dumbbell pieces will press down the receiving tray 121 by their own weight. At this time, the sleeve 22 will slide downward along the inside of the receiving frame 7 until the tooth head 23 is engaged with the gear ring 24. At this time, the rotation of the bevel tooth 114 will drive the sleeve 22 to rotate through the sleeve column 21, thereby forcing the receiving frame 7 and the entire transfer mechanism 12 to rotate. While the transfer mechanism 12 rotates, the support leg 123 will gradually slide with the guide slope 20, and the support leg 123 will be in a lifted state, which can drive one side of the top plate 122 to turn out of the receiving tray 121, forming an inclined slope effect, ensuring that a single dumbbell piece can slide freely and be picked up and packaged by the staff, facilitating the packaging work and preventing the dumbbell pieces in the stacked state from causing squeezing injuries to the workers' fingers.

[0050] The specific working principle and use method of the present invention are explained in detail below: When in use, the first step is to force the conveyor belt 2 to rotate along the conveyor frame 1 through the drive of the motor. After the dumbbell pieces are placed on the surface of the placement plate 3, they can be stably transported through the conveyor belt 2. The hydraulic cylinder 801 pushes the top cylinder 802 downward to force the top cylinder 802 to insert into the mounting hole in the middle of the dumbbell piece. At this time, the cylinder 13 works to force the pressing plate 803 to move downward along the inside of the top cylinder 802. At this time, the push rod 14 passes through the gap between the push rod 14 and the slide groove 15. The top tube 802 slides due to the sliding effect, and because the two ends of the top rod 14 are respectively hinged with the inside of the pressure plate 803 and the top of the bottom claw 804, the top rod 14 slides downward with the pressure plate 803 and drives the bottom claw 804 to expand from the bottom of the top tube 802 to the surrounding of the top tube 802, that is, the bottom claw 804 is inserted into the gap between the dumbbell piece and the placement plate 3, so as to grab the dumbbell piece from the top of the placement plate 3, forcing the grabbing mechanism 8 to move in the direction close to the transfer mechanism 12 following the conveyor belt 2 after grabbing the dumbbell piece;

[0051] In the second step, after the connecting column 17 slides along the slide 18 away from the end of the transfer mechanism 12 to the end close to the transfer mechanism 12, the connecting frame 4 and the connecting plate 5 slide to drive the grabbing mechanism 8 to move to the top of the receiving tray 121. At this time, the output end of the cylinder 13 retracts to force the four bottom claws 804 to retract, and the grabbed dumbbell pieces can be released in the receiving tray 121. At this time, the guide head 27 close to the transfer mechanism 12 will slide with the guide groove 26, forcing the connecting column 17 to enter the reset groove 19 from the slide 18. Because the dumbbell pieces will press down the two connecting pieces through the connecting plate 5 due to their own weight, the connecting plate 5 will press down the two connecting pieces. The connecting column 17, at this time, when the connecting column 17 moves into the reset groove 19, it will not mesh with the reset toothed belt 102. After the grabbing mechanism 8 completely releases the dumbbell plate, the spring 25 pushes the connecting column 17 upward, and the connecting column 17 will mesh with the reset toothed belt 102. At this time, the reset toothed belt 102 will drive the connecting column 17 and the entire grabbing mechanism 8 to slide along the reset groove 19 in a direction away from the transfer mechanism 12, and at the other end of the reset groove 19, the sliding effect between the guide head 27 and the guide groove 26 forces the connecting column 17 to re-enter the slideway 18 and perform the grabbing work again;

[0052] The third step is to receive the dumbbell pieces transported by the grabbing mechanism 8 through the receiving tray 121 close to one side of the conveyor belt 2, and the dumbbell pieces will press down the receiving tray 121 by their own weight. At this time, the sleeve 22 will slide downward along the inside of the receiving frame 7 until the tooth head 23 is engaged with the gear ring 24. At this time, the rotation of the bevel gear 114 will drive the sleeve 22 to rotate through the sleeve column 21, thereby forcing the receiving frame 7 and the entire transfer mechanism 12 to rotate. While the transfer mechanism 12 rotates, the support leg 123 will gradually slide with the guide slope 20, and the support leg 123 will be in a lifted state, which can drive one side of the top plate 122 to rotate out of the receiving tray 121, forming an inclined slope effect, ensuring that a single dumbbell piece can slide freely and be picked up and packaged by the staff.
