Description

Technical Field

[0001] The present invention relates to the field of material transportation, and particularly to a tennis rack assembly and transportation device. Background Art

[0002] During the material transportation process in a tennis rack assembly workshop, it is often necessary to stack and unstack materials to meet the transfer and transportation of materials. The existing material stacking and unstacking devices are carried out separately, that is, the materials are first stacked, then transferred to another production line, and then the materials are unstacked and then transported on the production line. The above process not only affects production efficiency, but also easily causes extrusion and damage to the materials when the products are stacked and unstacked. Summary of the Invention

[0003] In view of the above deficiencies of the prior art, the present invention provides a tennis rack assembly and transportation device that integrates stacking and unstacking, which not only avoids material extrusion but also improves the material transportation efficiency.

[0004] The object of the present invention is achieved through the following technical solutions:

[0005] A tennis rack assembly and transportation device includes a transfer device, a material transfer device, and a conveyor. The transfer device includes a base and a set of adjustment wheels installed at the lower part of the base. Two material transfer devices are symmetrically arranged on the transfer device. The material transfer device includes a frame. Four sprockets are rotatably connected to the frame. Chains are rotatably connected to the outside of the sprockets. A set of support devices are evenly connected to the chains. Each support device is slidably connected to the frame. The support device includes a support seat. The support seat is slidably connected to a support plate. The support plate is connected to the frame.

[0006] A support seat chute is provided on the end face of the support seat. A baffle is provided on one side of the support seat chute, and a bearing seat is provided on the other side of the support seat chute. A support plate slider is provided in the middle of the support plate. An intermediate plate is provided on the upper part of the support plate slider. An intermediate plate pin is provided on one side of the intermediate plate, and a guide rod is provided on the other side of the intermediate plate. The axes of the intermediate plate pin and the guide rod are perpendicular to each other. The support plate slider is slidably connected to the support seat chute. The support plate slider is between the baffle and the bearing seat. A spring is provided between the support plate and the support seat. The spring is sleeved outside the guide rod. The two sides of the spring respectively abut against the inner side of the baffle and the outer side of the intermediate plate.

[0007] A support frame is provided at the rear of the frame. Four sprocket holes distributed in a rectangle are provided at the four corners of the support frame. A sprocket is rotatably connected to each sprocket hole. The output shaft of a motor fixed to the frame is connected to one of the sprockets. Chains are rotatably connected to the outside of the four sprockets.

[0008] A first guide groove is provided on the end face of the frame. Second guide grooves and third guide grooves that are offset from each other are provided on the outside and inside of the first guide groove respectively. The first guide groove, the second guide groove, and the third guide groove have the same shape. The shape of the first guide groove is consistent with the movement trajectory of the chain.

[0009] Beneficial effects: When the supporting device of the present invention moves, the shaft slides in the first guide groove in the middle, and the two pins slide in the second guide grooves and the third guide grooves on both sides, so that the supporting device always moves in a parallel state. When the supporting device moves to the inside of the two transfer devices, the support plate extends to the outside of the frame. The two transfer devices are symmetrically arranged. Therefore, each supporting device of the two transfer devices is symmetrically arranged. The two symmetric support plates will simultaneously extend to the middle of the two transfer devices. The material is placed on the two symmetric support plates in the middle of the two transfer devices. The material is placed once, the motor is started once, and the material descends once with the supporting device. A new supporting device will rotate to the middle position above the two transfer devices to receive the material until all the supporting devices in the middle of the two transfer devices are filled with materials, and the materials are palletized. Each material is supported by the lower support plate, and there is a gap between adjacent materials. The upper materials will not squeeze the lower materials, and the reception of new materials will not affect the already received materials. The materials will not be squeezed or collided. When unstacking, the device together with the materials is placed on the upper part of the conveyor that needs to be unstacked, and the motor is started. The chain drives the supporting device to rotate. When the middle plate pin of the lowermost supporting device approaches the conveyor, the cam pushes the support plate outward, and the material between the two corresponding support plates falls onto the conveyor. As the motor keeps rotating, the materials between the two transfer devices continuously fall onto the conveyor. Since each material is supported by the support plate and is placed when approaching the conveyor, it avoids the extrusion or impact of the materials during the fall in the traditional unstacking device. The stacking and unstacking of the materials are completed in the same device, avoiding the transfer of the materials. The stacking and unstacking of the materials are carried out continuously, improving the conveying efficiency of the materials. Description of the Drawings

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0023] Refer to Figures 1 to 6 , a tennis rack assembly conveying device, including a transfer device 100, a material transfer device 200, and a conveyor 400. The transfer device 100 includes a base 110 and a set of adjustment wheels 120 installed at the lower part of the base 110. Two material transfer devices 200 are symmetrically arranged on the transfer device 100. The material transfer device 200 includes a frame 210. Four sprockets 220 are rotatably connected to the frame 210. A chain 240 is rotatably connected to the outside of the sprockets 220. A set of support devices 300 are evenly connected to the chain 240. Each support device 300 is slidably connected to the frame 210. The support device 300 includes a support base 310. The support base 310 is slidably connected to a support plate 320. The support plate 320 is connected to the frame 210.

[0024] Refer to Figures 10 to 12 , a support seat chute 311 is provided on the end face of the support base 310. A baffle 312 is provided on one side of the support seat chute 311. A bearing seat 313 is provided on the other side of the support seat chute 311. A support plate slider 321 is provided in the middle of the support plate 320. An intermediate plate 322 is provided on the upper part of the support plate slider 321. An intermediate plate pin 323 is provided on one side of the intermediate plate 322. A guide rod 324 is provided on the other side of the intermediate plate 322. The axes of the intermediate plate pin 323 and the guide rod 324 are perpendicular to each other. The support plate slider 321 is slidably connected to the support seat chute 311. The support plate slider 321 is between the baffle 312 and the bearing seat 313. A spring 330 is provided between the support plate 320 and the support base 310. The spring 330 is sleeved outside the guide rod 324. The two sides of the spring 330 respectively abut against the inner side of the baffle 312 and the outer side of the intermediate plate 322.

[0025] Refer to Figures 3 to 9, a support frame 216 is provided at the rear side of the frame 210. Four sprocket holes 217 distributed in a rectangle are provided at the four corners of the support frame 216. A sprocket 220 is rotatably connected in each sprocket hole 217. The output shaft of a motor 230 fixed to the frame 210 is connected to one of the sprockets 220, and a chain 240 is rotatably connected to the outside of the four sprockets 220.

[0026] Reference Figures 3 to 9 , a first guide groove 211 is provided on the end face of the frame 210. A second guide groove 212 and a third guide groove 213 which are offset from each other are respectively provided on the outside and the inside of the first guide groove 211. The first guide groove 211, the second guide groove 212, and the third guide groove 213 have the same shape, and the shape of the first guide groove 211 is consistent with the movement track of the chain.

[0027] Reference Figures 3 to 9 , a triangular plate 314 is provided on the side surface of the support seat 310. A shaft 315 is provided at the lower part of the triangular plate 314, and two symmetric pins 316 are provided at the upper part of the triangular plate 314. The shaft 315 passes through the first guide groove 211 and is connected to the intermediate shaft of a link of the chain 240, and the two pins 316 are respectively slidably connected to the second guide groove 212 and the third guide groove 213 on both sides.

[0028] Reference Figures 3 to 9, a side plate 214 is provided inside the frame 210, and a cam 215 is provided at the lower part of the side plate 214. When the support seat 310 slides to one side of the side plate 214, the intermediate plate pin 323 slides along the inner side of the side plate 214. When the intermediate plate pin 323 slides to the cam 215, the support plate 320 retracts under the drive of the cam 215. After the intermediate plate pin 323 slides past the cam 215, the support plate 320 resets under the action of the spring 330. When the motor 230 rotates, it drives the sprocket 220 and the chain 240 to rotate. When the chain 240 rotates, it drives a set of support devices 300 to move along the trajectory of the movement of the chain 240. When the support device 300 moves, the shaft 315 slides in the middle first guide groove 211, and the two pins 316 slide in the second guide grooves 212 and the third guide grooves 213 on both sides, so that the support device 300 always moves in a parallel state. When the support device 300 moves to the inside of the two transfer devices 200, the support plate 320 extends to the outside of the frame 210. The two transfer devices 200 are symmetrically arranged. Therefore, each support device 300 of the two transfer devices 200 is symmetrically arranged. The two symmetric support plates 320 will simultaneously extend between the two transfer devices 200. The material is placed on the two symmetric support plates 320 between the two transfer devices 200. The material is placed once, and the motor 230 is started once. The material descends once with the support device 300, and a new support device 300 will rotate to the middle position above the two transfer devices 200 to receive the material until all the support devices 300 between the two transfer devices 200 are filled with materials. The materials are stacked. Each material is supported by the lower support plate 320, and there is a gap between adjacent materials. The upper materials will not squeeze the lower materials. When unstacking, the device together with the materials is placed on the upper part of the conveyor that needs to be unstacked, and the motor 230 is started. The chain 240 drives the support device 300 to rotate. When the lowermost support device 300 approaches the conveyor 400, the intermediate plate pin 323 of the lowermost support device 300 touches the cam 215, and the cam 215 pushes the support plate 320 outward. The material between the two corresponding support plates 320 falls onto the conveyor 400. As the motor 230 keeps rotating, the materials between the two transfer devices 200 continuously fall onto the conveyor 400. Since each material is supported by the support plate 320 and is put down when approaching the conveyor 400, it avoids the extrusion or impact when the materials of the traditional unstacking device fall, ensuring safety.

[0029] An operating method of a tennis racket assembling and conveying device. In the first step, when using this device, there are two usage modes. The first is the palletizing mode. In the palletizing mode, move this device to the position where materials are received, and place the materials on the two uppermost support plates 320 between the two material transfer devices 200. In the second step, then start the motor 230 to lower the placed materials, and the new support device 300 rotates to the middle position above the two material transfer devices 200 to continue receiving materials until all the support devices 300 between the two material transfer devices 200 are filled with materials and the materials are palletized. After the materials are palletized, move this device together with the materials above the unstacking conveyor 400, start the motor 230, and the chain 240 drives the support device 300 to rotate. When the lowermost support device 300 approaches the conveyor 400, the middle plate pin 323 of the lowermost support device 300 touches the cam 215, and the cam 215 pushes the support plate 320 outward, and the materials between the two corresponding support plates 320 fall onto the conveyor 400. As the motor 230 keeps rotating, the materials between the two material transfer devices 200 continuously fall onto the conveyor 400.

[0030] When the supporting device 300 moves, the shaft 315 slides in the middle first guide groove 211, and the two pins 316 slide in the second guide grooves 212 and the third guide grooves 213 on both sides, so that the supporting device 300 always moves in a parallel state. When the supporting device 300 moves to the inner side of the two material transfer devices 200, the support plate 320 extends to the outside of the frame 210. The two material transfer devices 200 are symmetrically arranged. Therefore, each supporting device 300 of the two material transfer devices 200 is symmetrically arranged. The two symmetric support plates 320 will simultaneously extend between the two material transfer devices 200. The material is placed on the two symmetric support plates 320 between the two material transfer devices 200. The motor 230 is started once for each placement of the material, and the material descends once with the supporting device 300. A new supporting device 300 will rotate to the middle position above the two material transfer devices 200 to receive the material until all the supporting devices 300 between the two material transfer devices 200 are filled with materials. The materials are palletized. Each material is supported by the lower support plate 320. There is a gap between adjacent materials. The upper materials will not squeeze the lower materials, and the reception of new materials will not affect the already received materials. The materials will not be squeezed or collided. When depalletizing, the device together with the materials is placed on the upper part of the conveyor that needs to be depalletized, and the motor 230 is started. The chain 240 drives the supporting device 300 to rotate. When the lowermost supporting device 300 approaches the conveyor 400, the middle plate pin 323 of the lowermost supporting device 300 touches the cam 215, and the cam 215 pushes the support plate 320 outward. The material between the two corresponding support plates 320 falls onto the conveyor 400. As the motor 230 keeps rotating, the materials between the two material transfer devices 200 continuously fall onto the conveyor 400. Since each material is supported by the support plate 320 and is placed when approaching the conveyor 400, it avoids the extrusion or impact of the materials during the fall in the traditional depalletizing device. The palletizing and depalletizing of the materials are completed in the same device, avoiding the transfer of the materials, with good safety effect. The palletizing and depalletizing of the materials are carried out continuously, improving the conveying efficiency of the materials.
