Description

Technical Field

[0001] The present application relates to the field of transmission mechanisms, and in particular to a plastic barrel material receiving device. Background Art

[0002] In the transfer industry, the shapes of the workpieces to be transferred are mostly cylindrical or conical. During the transfer process, the limiting method of the workpiece transfer process is relatively simple due to the limitations of its own structure. In addition, in order to improve the transfer efficiency and reduce the space for storing workpieces, the workpieces are transferred after being stacked. When unloading, it is also necessary to ensure the number of workpieces separated each time and the neatness of the workpieces after storage.

[0003] At present, the barrel automatic printing machine counts the barrels collected by the following method: the products are transported out of the barrel outlet of the automatic printing machine through the conveyor line, and then stacked and counted by humans. Since manual counting is limited by the operator's ability, there is a problem of counting errors, which easily affects the neatness of the workpieces after collection. At the same time, the workpieces are collected by falling under their own weight during the unloading process. If the workpiece falls to a large height, it will bump against itself and be damaged.

[0052] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0053] Reference Figure 1-3 As shown, in some embodiments of the present application, a plastic barrel receiving device is provided, comprising: a conveyor belt and a receiving assembly 3. The conveyor belt is used to transmit the plastic barrel 4, and the conveyor belt comprises a first conveyor belt 1 and a second conveyor belt 2 arranged in sequence, and the second conveyor belt 2 comprises a driving unit 21 and a conveyor belt 22, and the driving unit 21 is used for the conveyor belt 22 to run, so that the plastic barrel 4 can move on the conveyor belt 22.

[0054] The material receiving assembly 3 is located at the downstream end of the conveyor belt. Specifically, the two ends of the conveyor belt 22 are respectively a feed end 222 and a discharge end 223. The first conveyor belt 1 is arranged close to the feed end 222 of the second conveyor belt 2. Conversely, the material receiving assembly 3 is arranged close to the discharge end 223 of the second conveyor belt 2, so that the plastic barrel 4 flows from the first conveyor belt 1 to the second conveyor belt 2, and then is transferred from the second conveyor belt 2 to the material receiving assembly 3.

[0055] Meanwhile, in the present solution, the receiving assembly 3 includes a flip unit 31, a hopper 32 and a counting unit 33. The counting unit 33 is arranged between the flip unit 31 and the conveyor belt. The flip unit 31 can flip between the counting unit 33 and the hopper 32, so that the plastic barrel 4 passing through the counting unit 33 is flipped onto the hopper 32 via the flip unit 31. Specifically, the counting unit 33 is arranged near the discharge end 223, and the plastic barrel 4 flows out from the discharge end 223 and passes through the counting unit 33. The plastic barrel 4 flowing out of the second conveyor belt 2 is automatically counted by the counting unit 33. Exemplarily, in the vertical direction, the height of the counting unit 33 and / or the discharge end 223 is greater than the highest point of the hopper 32. The flip unit 31 flips the plastic barrel 4 at a high position onto the hopper 32 at a low position. The surface on the hopper 32 for circulating the plastic barrel 4 is a slope, and the end of the slope close to the flip unit 31 is the highest point of the hopper 32. After the plastic barrel 4 is transferred to the slope, the plastic barrel 4 will slide or roll toward the other end of the slope away from the turning unit 31 due to its own gravity.

[0056] In this solution, the turning unit 31 transfers the plastic barrel 4 to the hopper 32, and the height difference between the two ends of the slope on the hopper 32 is smaller, which reduces the gravitational potential energy of the plastic barrel 4, thereby reducing the inertia of the plastic barrel 4 at the low position of the slope. In addition, since the height difference between the two ends of the slope on the hopper 32 is small, the length of the slope can be reduced, thereby reducing the footprint of the hopper 32.

[0057] Further, refer to Figure 5 As shown, the turning unit 31 includes a first turning module 312 and a second turning module 313 . The plastic barrel 4 is transferred to the first turning module 312 through the counting unit 33 . The first turning module 312 turns the workpiece to the second turning module 313 . The second turning module 313 turns the plastic barrel 4 to the hopper 32 .

[0058] Specifically, the flip unit 31 further includes a base 311, which serves as a mounting structure for the first flip module 312 and the second flip module 313. On the one hand, the first flip module 312 includes a first material receiving trough 3121, a first swing arm, and a first cylinder 3123. The first material receiving trough 3121 is mounted at one end of the first swing arm, the other end of the first swing arm is rotatably connected to the base 311, and the power output end of the first cylinder 3123 is connected to the first swing arm.

[0059] On the other hand, the second flip module 313 includes a second material receiving trough 3131, a second swing arm 3132 and a second cylinder 3134. The second material receiving trough 3131 is installed at one end of the second swing arm 3132. The other end of the second swing arm 3132 is rotatably connected to the base 311. The power output end of the second cylinder 3134 is connected to the second swing arm 3132. The length of the second swing arm 3132 is greater than that of the first swing arm.

[0060] Furthermore, the surfaces of the first receiving groove 3121 and the second receiving groove 3131 contacting the plastic barrel 4 are both V-shaped, and the length of the first receiving groove 3121 contacting the surface of the plastic barrel 4 is less than the length of the second receiving groove 3131 contacting the surface of the plastic barrel 4. Specifically, the first receiving groove 3121 has a first left contact surface and a first right contact surface, the first left contact surface and the first right contact surface are tangent to the side of the plastic barrel 4, and the first left contact surface and the first right contact surface are relatively inclined to form a V shape. The second receiving groove 3131 has a second left contact surface and a second right contact surface tangent to the side of the plastic barrel 4, and the second left contact surface and the second right contact surface are relatively inclined to form a V shape.

[0061] The lengths of the first left contact surface and the first right contact surface are both shorter than the lengths of the second left contact surface and the second right contact surface. Exemplarily, the lengths of the first left contact surface and the first right contact surface are consistent, and the lengths of the second left contact surface and the second right contact surface are consistent.

[0062] In this solution, the length of the first swing arm is much smaller than the length of the second swing arm 3132, so that the moving path of the plastic bucket 4 driven by the first receiving trough 3121 is short, that is, the plastic bucket 4 stays on the first receiving trough 3121 for a short time. Since the first receiving trough 3121 is short, it is more convenient for the plastic bucket 4 to detach from the first receiving trough 3121, and the length of the second swing arm 3132 is long, and the plastic bucket 4 stays on the second receiving trough 3131 for a long time. The second receiving trough 3131 is designed to be longer so that it can be more stably stored in the second receiving trough 3131. In addition, the second receiving trough 3131 is located below the first receiving trough 3121. If the plastic bucket 4 detaches from the first receiving trough 3121, the second receiving trough 3131 is longer and can also receive the plastic bucket 4 detached from the first receiving trough 3121.

[0063] Under the driving of the first cylinder 3123, the first material receiving groove 3121 can be turned over from the initial position to the final position. Under the driving of the second cylinder 3134, the second material receiving groove 3131 can be turned over from the initial position to the final position.

[0064] The initial position of the second material receiving trough 3131 is connected to the terminal position of the first material receiving trough 3121 , and the terminal position of the second material receiving trough 3131 is connected to the hopper 32 , so that the second material receiving trough 3131 is close to the feed port 321 .

[0065] The specific process of transferring the plastic barrel 4 to the hopper 32 is as follows: when the first receiving trough 3121 is in the initial position, the first receiving trough 3121 corresponds to the counting unit 33, so that the plastic barrel 4 is conveniently transferred to the first receiving trough 3121. The initial position of the second receiving trough 3131 is connected to the terminal position of the first receiving trough 3121, so that the first right contact surface and the second left contact surface are located on the same plane, and the plastic barrel 4 can flow along the first right contact surface to the second left contact surface. The terminal position of the second receiving trough 3131 is connected to the hopper 32, so that the second right contact surface and the slope of the hopper 32 are located on the same plane or the second right contact surface is attached to the slope surface of the hopper 32, and the plastic barrel 4 flows to the hopper 32 along the second right contact surface.

[0066] In some embodiments of the present application, reference Figure 6 As shown, the counting unit 33 includes a support portion 331 and a counter 332. The support portion 331 is located at the downstream end of the conveyor belt, and the counter 332 is arranged on one side of the support portion 331. The plastic barrels 4 are conveyed along the support portion 331 and pass through the counter 332 in sequence.

[0067] Furthermore, columns 333 are provided on both sides of the support portion 331, and check portions 334 are installed on the columns 333. The check portions 334 are located on the transmission path of the plastic barrel 4 on the support portion 331, and the check portions 334 are located on the upstream side of the counter 332. The check portions 334 restrict the plastic barrel 4 from retreating, which causes the counter 332 to count repeatedly. In addition, the check portions 334 provide a certain supporting force for the plastic barrel 4 on the support portion 331, and when the plastic barrel 4 continuously passes through the check portions 334, the plastic barrel 4 can also achieve the purpose of palletizing.

[0068] At the same time, a limiting portion 335 is installed on one end of the column 333 away from the support portion 331, and the limiting portion 335 is located above the support portion 331. The limiting portion 335 limits the plastic barrel 4 from being squeezed by the non-return portion 334 and jumping upward to break away from the non-return portion 334.

[0069] Furthermore, the column 333 includes a main column and a sliding column, and the main column and the sliding column are slidably arranged. Specifically, the check portion 334 is slidably connected to the main column and the sliding column respectively, and the check portion 334 is also configured with a limiter, which can fix the check portion 334 at a specified position of the main column and the sliding column. The limiter 335 is installed on the top of the sliding column, and the limiter 335 slides relative to the limiter through the sliding column, thereby adjusting the distance between the limiter 335 and the support portion 331 in the vertical direction. The main columns on both sides of the support portion 331 are threadedly connected by an adjusting hand wheel, and the two main columns can achieve relative movement under the drive of the adjusting hand wheel, thereby adjusting the distance between the two check portions 334 and the two limit portions 335.

[0070] In the above solution, by adjusting the vertical distance between the limiting portion 335 and the supporting portion 331 and adjusting the distance between the two check portions 334 and between the two limiting portions 335 , the supporting portion 331 can be compatible with plastic barrels 4 of different diameters.

[0071] In some embodiments of the present application, the plastic barrel receiving device further includes a push assembly, which is electrically connected to the counting unit 33 and is located between the counting unit 33 and the first flip module 312; the push assembly pushes the plastic barrel 4 passing through the counting unit 33 to the first flip module 312. When the first receiving groove 3121 is in the initial position, the first receiving groove 3121 corresponds to the counting unit 33, specifically, the surface of the support portion 331 contacting the plastic barrel 4 is V-shaped, and the surface of the support portion 331 contacting the plastic barrel 4 is aligned with the surface of the first receiving groove 3121 contacting the plastic barrel 4, that is, the two V-shaped contact surfaces are arranged in parallel in a one-to-one correspondence, and the surface of the first receiving groove 3121 contacting the plastic barrel 4 is not higher than the surface of the support portion 331 contacting the plastic barrel 4, so that the push assembly can push the stacked plastic barrel 4 from the support portion 331 to the first receiving groove 3121.

[0072] In some embodiments of the present application, reference Figure 4 As shown, the first conveyor belt 1, the second conveyor belt 2 and the receiving assembly 3 are arranged in sequence along the conveying direction. The second conveyor belt 2 includes a driving unit 21 and two conveyor belts 22. The two conveyor belts 22 are arranged relative to each other so that the two conveyor belts 22 form an angle, and the driving unit 21 drives the two conveyor belts 22 at the same time. Exemplarily, the two conveyor belts 22 are arranged vertically, that is, the angle formed by the two conveyor belts 22 is 90°.

[0073] In this solution, the driving unit 21 includes a motor 211 and a mutually meshing driving bevel gear 213 and a driven bevel gear 214. The driving bevel gear 213 and one of the transmission belts 22 are connected to an output shaft 212 as a power transmission end of the motor 211, and the driven bevel gear 214 is connected to the other transmission belt 22. The belt 221 on the transmission belt 22 is driven to move by the same motor 211.

[0074] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific implementations. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be understood to be within the scope of protection of the present application.
