Description

Technical Field

[0001] The utility model relates to the technical field of can processing auxiliary equipment, in particular to a can sorting device. Background Art

[0002] Canned products generally need to be canned in a quantitative manner to ensure that they meet the nominal specifications. In the prior art, cans are generally transported by conveyor belts after filling. During the transportation process, they can be weighed by belt weighing machines to ensure that there is no large error in the weight of the product. For example, a belt checkweigher with the authorization announcement number CN 221325630 U can be used, which includes a feeding belt conveyor and a weighing unit. The weighing unit includes a weighing sensor and a weighing belt conveyor. The weighing belt conveyor includes a weight transfer frame, a weighing belt, a weighing belt drive device and at least two belt shafts that are parallel to each other and horizontally arranged. The belt shaft of the weighing belt conveyor close to the feeding belt conveyor is called the first weighing belt shaft, the belt shaft of the feeding belt conveyor away from the first weighing belt shaft is called the first feeding belt shaft, and the belt shaft of the feeding belt conveyor close to the first weighing belt shaft is called the second feeding belt shaft. The portion of the heavy belt shaft that is wrapped by the weighing belt is cantilevered relative to the weight transfer frame, and the portion of the second feeding belt shaft that is wrapped by the feeding belt is also cantilevered relative to the feeding frame. The extension direction of the second feeding belt shaft is parallel to the cantilevered extension direction of the first weighing belt shaft. Those that fail to meet the weighing requirements can be rejected using the provided air nozzle or the push rod driven by components such as the cylinder. However, in actual operation, when rejecting tinplate canned products, the air nozzle may not be able to blow, and using the push rod may push to the side of the can, causing it to be misaligned (only facing it can ensure smooth pushing).

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] In an exemplary embodiment, Figure 1 、 2 As shown, this embodiment provides a can sorting device, which includes a weighing belt 1 and a rejecting belt 2. A mounting frame is provided above the rejecting belt 2, and a push plate 4 that can move back and forth between the two sides of the rejecting belt 2 is provided on the mounting frame. The push plate 4 is an arc-shaped plate and the arc-shaped opening of the arc-shaped plate is located on the side facing the rejecting belt 2. A driver 5 for driving the push plate 4 to move is also provided on the mounting frame, and the driver 5 and the weighing belt 1 and the rejecting belt 2 are also electrically connected to a controller. A conveyor belt 6 for conveying can also be further provided behind the rejecting belt 2.

[0024] In the above embodiment, the push plate 4 with an arc-shaped plate structure is used to push the cans 3, and the arc-shaped opening is facing the cans 3 that need to be rejected. During the movement, the cans 3 are allowed to enter and then pushed. During the process, the push plate 4 and the cans 3 are not easily misaligned, which solves the problem in the prior art that the cans 3 that fail to be blown or pushed may be misaligned when rejecting the unqualified cans 3; in a more specific solution, the driver 5 used can be a cylinder, which is installed on the mounting frame and the output end extends horizontally and is fixedly connected to the side of the push plate 4 away from the arc-shaped opening.

[0025] In further solutions, such as Figure 1 、 2 As shown, a solution is also provided in which the driver 5 is a first driving motor. Specifically, the mounting frame includes a first mounting plate 7 located above the reject belt 2, and a second mounting plate 8 and a third mounting plate 9 fixedly connected to both ends of the first mounting plate 7 and located on both sides of the reject belt 2. In more detail, the driver 5 includes a first driving motor mounted on the first mounting plate 7, the first driving motor is connected to a driving shaft 10, a moving block 11 is threadedly provided on the driving shaft 10 and is slidably matched with the first mounting plate 7, the push plate 4 is fixedly connected to the moving block 11, and the can 3 is in After being weighed on the weighing belt 1, it is conveyed to the rejecting belt 2. When the weighing on the weighing belt 1 fails to meet the standards, the weighing belt 1 sends an unqualified signal to the controller. The controller sends an instruction to the first drive motor according to the signal to start the first drive motor, driving the push plate 4 to move. During the movement, it contacts the can 3 and pushes the can 3 to the other side, and finally pushes it away from the rejecting belt 2 (in particular, the two sides of the belt wrapped around the rejecting belt 2 are flush with or slightly higher than the two side casings of the rejecting belt 2, so as to ensure that the casing will not block the can 3 from leaving from the side).

[0026] In more detail, in this scheme, the first driving motor is installed on the first mounting plate 7, and by driving the driving shaft 10 to rotate, the driving shaft 10 and the moving block 11 are threadedly engaged, and the moving block 11 is slidably engaged with the sliding groove 13 provided on the first mounting plate 7, so that the moving block 11 can move with the rotation of the driving shaft 10, and the forward / reverse rotation of the first driving motor realizes the reciprocating movement of the push plate 4. The width of the arc opening of the arc plate can also be greater than the diameter of the can 3, so that the can 3 can enter the arc opening more smoothly. Specifically, a sliding groove 13 is recessed on the lower wall surface of the first mounting plate 7, and the first driving motor has a rotating shaft that rotates through the first mounting plate 7 and extends into the sliding groove 13, and the rotating shaft is fixedly connected to the driving shaft 10, and at the same time, the end of the driving shaft 10 facing away from the first driving motor is rotatably connected to the inner wall surface of the sliding groove 13, so that both ends of the driving shaft 10 are rotatably connected, thereby having better stability.

[0027] like Figure 1 、 2As shown, further, the push plate 4 is fixedly connected to a connecting rod 14, and the upper end of the push plate 4 is also fixedly connected to a cover plate 15, and the connecting rod 14 is fixedly connected to the cover plate 15, and the connecting rod 14 also extends into the sliding groove 13 and is fixedly connected to the moving block 11, and the connecting rod 14 extends upward and then connects to the moving block 11 in the sliding groove 13, so that it moves back and forth under the drive of the moving block 11, and finally drives the push plate 4 to move back and forth. In particular, there is a small gap between the lower end surface of the push plate 4 and the reject belt 2 to ensure that the two do not contact each other and operate independently of each other; further, during the weighing process, the weighing belt 1 first drives the cans 3 to the middle position, then stops and weighs, and then runs The cans 3 are sent to the rejection belt 2, and the rejection belt 2 runs to send the cans 3 to the position opposite the push plate 4. If there is no problem with the weighing of the weighing belt 1 in the previous step, the first drive motor will not run, and the cans 3 are sent to the rear conveyor belt 6 via the rejection belt 2 to continue the conveying operation. If the weighing is abnormal, the controller will give an instruction, the rejection belt 2 is in a stationary state, and the first drive motor runs to drive the push plate 4 to move; in further detail, the first mounting plate 7 is also fixed with a support bar 16 extending into the sliding groove 13 and located on both sides of the connecting rod 14. The bottom wall of the moving block 11 is in sliding contact with the two support bars 16. The support bar 16 provided below provides upward support to make the moving block 11 more stable.

[0028] like Figure 1 、 2 As shown, a transition roller 17 is also provided for self-rotation between the weighing belt 1, the rejecting belt 2 and the conveying belt 6 (a conveying belt 6 can also be added in front of the weighing belt 1 to deliver the cans 3 to the weighing belt 1, and a transition roller 17 can also be provided between the weighing belt 1 and the conveying belt 6 in front). In this way, the transition roller 17 can enable the cans 3 to move more smoothly between the weighing belt 1, the rejecting belt 2 and the conveying belt 6. In more detail, two second drive motors 18 are also installed on the second mounting plate 8 to drive the two transition rollers 17 respectively (the end of the transition roller 17 facing away from the second drive motor 18 can also be rotatably connected to the third mounting plate 9 (only the scheme connected to the second mounting plate 8 is shown in the accompanying drawings)); further, a material receiving trough 12 is also fixedly connected to the third mounting plate 9 and is located below the side of the rejecting belt 2, and the material receiving trough 12 is opposite to the arc-shaped opening. The material receiving trough 12 is used to catch the unqualified cans 3 pushed down, and a material receiving container can also be placed below the material receiving trough 12 to facilitate the recycling of the cans 3.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
