Description

Technical Field

[0001] The invention belongs to the field of aerated concrete product production equipment, and in particular relates to a method and a device for sorting and grouping aerated concrete products. Background Art

[0002] The existing packaging of aerated concrete products generally adopts the method of packaging the whole aerated concrete products after leaving the kettle, and the aerated concrete products are not disassembled and sorted, so there are damaged products in the product brick piles transported to the site. In order to sort out the damaged products, the aerated concrete products must be decomposed into single-layer blanks and sorted, and then grouped and stacked. Therefore, the grouping of aerated concrete products after sorting becomes an important part of the sorting and packaging of aerated concrete products.

[0003] In the prior art, damaged products are usually picked out manually. Since a single product is heavy and occasionally sticks together, the production line needs to be stopped. The workload of workers is heavy and the labor intensity is high, resulting in brick breakage and low picking efficiency. When there are many damaged products, the continuous operation of the production line is affected, resulting in increased production costs. Summary of the invention

[0004] The purpose of the present invention is to provide a method and device for sorting and grouping aerated concrete products. On the basis of the original grouping and packaging production line, a device for regrouping after sorting damaged products is set, and then the original stacking device is used for stacking. The device and method can not only solve the problem that aerated concrete product sorting requires a lot of manpower, but also is not easy to cause new damage to bricks, and can meet the needs of continuous operation of the production line, automatic grouping and packaging.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: a method for sorting and grouping aerated concrete products, comprising the following steps:

[0006] Step 1: During the operation of the main marshaling conveyor line in the marshaling and packaging production line, the damaged products on the main marshaling conveyor line are identified by using the identification system, and then the sorting fixture clamps a group of products including the damaged products and leaves the main marshaling conveyor line, the clamping piece group corresponding to the damaged products in the sorting fixture is released, and the damaged products are thrown into the designated area, and then the sorting fixture puts the remaining intact products on the brick collection conveyor line on one side of the main marshaling conveyor line;

[0007] Step 2: The brick collection conveyor line conveys the products to the sorting and grouping conveyor line, and the gaps between the products are eliminated by starting and stopping the brick collection conveyor line and the sorting and grouping conveyor line, and the products are grouped;

[0008] Step three, the palletizing device clamps the product group on the sorting and grouping conveyor line and puts it on the packaging conveyor line to wait for packaging, or the palletizing device places the clamped product group on the brick separation platform, and the brick separation platform reserves a forklift hole in the product group.

[0009] An aerated concrete product sorting and grouping device is arranged on one side of a grouping and packaging production line, comprising an identification system, a sorting fixture, a brick collection conveyor line, a sorting and grouping conveyor line and a brick separation platform. The identification system is arranged on the main grouping conveyor line of the grouping and packaging production line to identify damaged products on the main grouping conveyor line in the grouping and packaging production line, and send the position information of the damaged products in the grouping to the controller of the sorting fixture; the sorting fixture is used to grab a whole group of products containing damaged products, and throw the damaged products to a designated area, and put the remaining intact products on the brick collection conveyor line. The brick collection conveyor line and the sorting and grouping conveyor line cooperate to group the intact products.

[0010] The brick collection conveyor line and the sorting and grouping conveyor line are connected front and back according to the conveying direction of the aerated concrete products and are parallel to the main grouping conveyor line. The end of the sorting and grouping conveyor line is arranged within the working range of the stacking device.

[0011] The brick collecting conveying line and the sorting and grouping conveying line are respectively provided with independent power.

[0012] The sorting fixture comprises a mounting bracket, a plurality of clip groups that can be controlled individually, and a driving mechanism for controlling the opening and closing of each clip group.

[0013] The brick-dividing platform is arranged on one side of the sorting and grouping conveying line and is located within the working range of the stacking device. The brick-dividing platform is used to reserve a forklift hole in the product group.

[0014] The beneficial effects of the present invention are as follows: first, through the cooperation of the identification system, the sorting fixture, the brick collection conveyor line, the sorting and grouping conveyor line, and the brick separation platform, the present invention can sort out the damaged products and re-group and stack the remaining intact products while maintaining the continuous conveying of the original grouping and packaging production line. The whole process does not affect the normal operation of the original main grouping conveyor line, and can meet the requirements of continuous automated production of sorting, grouping, and stacking of aerated concrete products. The device used will not change the overall layout of the original equipment, so it is very suitable for modification of existing production lines.

[0015] Second, the sorting fixture in the present invention includes multiple groups of independently movable clip groups, and each group of clip groups corresponds to a row of products. In this way, the movement of the corresponding clip groups can be accurately controlled to loosen the row of products containing damaged products and drop them into a designated area without affecting the clamping of the products by other clip groups. Therefore, after the sorting fixture places the remaining intact products on the brick collection conveyor line, these products can be regrouped.

[0016] Thirdly, the brick-dividing platform of the present invention can reserve a forklift hole in the product group by pushing the movable plate to move linearly, and has a simple structure, convenient operation and easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the invention in any way.

[0025] Referring to the accompanying drawings, an aerated concrete product sorting and grouping device includes an identification system, a sorting fixture I, a brick collection conveyor line IV, a sorting and grouping conveyor line V and a brick separation platform VI. The identification system is arranged on the main grouping conveyor line II of the grouping and packaging production line to identify damaged products on the main grouping conveyor line II; the brick collection conveyor line IV and the sorting and grouping conveyor line V are connected front and back according to the product conveying direction and are parallel to the main grouping conveyor line II; the sorting fixture I is provided with a plurality of groups of clip groups 3.2 that can act independently, and the controller of the sorting fixture I can control the corresponding clip group 3.2 to loosen according to the identification result of the identification system to discard the damaged products; the brick separation platform VI is arranged on one side of the sorting and grouping conveyor line V and is located within the working range of the stacking device VII. The brick separation platform VI is used to reserve a forklift hole in the product group.

[0026] The identification system includes a camera and an identification component. The camera is installed on both sides of the main assembly conveyor line II, takes pictures or videos from both sides and above the product group on the conveyor line, and sends the collected picture information or video information to the identification component, which identifies the damaged product and its position information in the product group, and sends the position information to the PLC controller of the sorting fixture I. The sorting fixture I grabs the product group where the damaged product is located according to the position information, releases the clip group corresponding to the position of the damaged product, and throws away the damaged product, while other intact products are sent to the brick collection conveyor line IV by the sorting fixture I. This part of the identification system is a common equipment in the industrial field, so it can be purchased from the market.

[0027] The structure of the sorting fixture I is as follows Figure 2 , 3 As shown, it includes a mounting bracket 3.1, multiple clip groups 3.2 and a driving mechanism for controlling the opening and closing of each clip group. Each clip group 3.2 includes two clips movably mounted on the mounting bracket 3.1, and each clip group 3.2 is provided with a driving mechanism. The driving mechanism is preferably a mechanism that can achieve linear telescopic movement, such as a cylinder 3.3, an oil cylinder, an electric push rod, etc. The two ends of the driving mechanism that can move relatively are respectively fixed on the two clips of a clip group 3.2. Figure 3 As shown, this embodiment uses cylinder 3.3 as the driving mechanism, and when the cylinder 3.3 is installed, the directions of adjacent cylinders 3.3 are opposite, which can reduce the distance between the cylinders 3.3 and reduce the volume of the sorting fixture. Therefore, when other driving mechanisms are used, they can also be installed in opposite directions to reduce the gap between the two driving devices. Figure 2 In the figure, two groups of clamping plates 3.2 clamp a row of products. When the product size and weight are small, only one group of clamping plates 3.2 is needed for a row of products. If the products are larger, multiple groups of clamping plates 3.2 are needed to clamp a row of products together. Therefore, it can be selected according to the actual situation.

[0028] The mounting bracket 3.1 of the sorting fixture I is mounted on a robotic arm, and the movement of the sorting fixture I is controlled by the robotic arm.

[0029] The structure of the brick collection conveyor line IV is as follows Figure 4 As shown, it includes a frame 1.1, a chain conveying mechanism 1.2 and a motor reducer 1.3. The chain conveying mechanism 1.2 is installed on the upper part of the frame 1.1 through a seat bearing, and uses the upper surface of the chain to convey the products. The motor reducer 1.3 is installed inside the frame 1.1 and fixed to the frame 1.1 by bolts. The motor reducer 1.3 is connected to the chain conveying frame 1.2 through a chain drive to transmit power. The chain conveying mechanism 1.2 continuously conveys products to one end. When the sorting and marshaling conveying line V stops running and blocks the products, the gaps between the products formed by the damaged products being picked out can be eliminated.

[0030] The overall structure of the sorting and marshaling conveyor line V is similar to that of the brick collection conveyor line IV, except that the driven end of the sorting and marshaling conveyor line V is connected to the drive shaft of the brick collection conveyor line IV, that is, the driven wheel of the driven end of the sorting and marshaling conveyor line V is installed crosswise with the driving wheel on the drive shaft of the brick collection conveyor line IV as an idler wheel. Therefore, when the brick collection conveyor line IV is running, the driven wheel on the sorting and marshaling conveyor line V will not rotate with it, that is to say, the brick collection conveyor line IV and the sorting and marshaling conveyor line V are both independently operated, and an independent motor reducer is also provided at the active end of the sorting and marshaling conveyor line V. On this basis, the brick collection conveyor line IV and the sorting and marshaling conveyor line V can be coordinated by start and stop to regroup the sorted products as required. The outlet end of the sorting and marshaling conveyor line V is located within the working range of the palletizing device VII, and the palletizing device VII grabs the grouped products to the packaging conveyor line III and waits for packaging.

[0031] The brick-dividing platform VI includes a brick-dividing platform frame 2.1, a fixed plate 2.6, a movable plate 2.7 and a linear drive mechanism. The fixed plate 2.6 and the movable plate 2.7 are used to support the product group placed, and the linear drive mechanism is used to drive the movable plate 2.7 to move linearly relative to the fixed plate 2.6. The fixed plate 2.6 is fixed to the middle of the brick-dividing platform frame 2.1. The movable plate 2.7 is provided with two pieces, which are respectively located on both sides of the fixed plate 2.6. The plate surfaces of the movable plate 2.7 and the fixed plate 2.6 are flush. The linear drive mechanism includes a dual-output shaft reduction motor 2.2 and two ball screws 2.4. The threads on the two ball screws 2.4 have opposite rotation directions. The nut 2.5 on each threaded screw 2.4 is connected to one of the movable plates 2.7 through a connecting piece. Preferably, a slider 2.3 is further provided at the bottom of the movable plate 2.7, and a track for the slider 2.3 to slide is correspondingly provided on the brick-splitting platform frame 2.1, which can serve as a movable guide for the movable plate 2.7 and support the movable plate 2.7 and reduce sliding friction.

[0032] The method for sorting and grouping aerated concrete products using the above-mentioned sorting and grouping device is as follows:

[0033] Step 1: During the operation of the main marshaling conveyor line in the marshaling and packaging production line, the damaged products on the main marshaling conveyor line are identified by using the identification system, and then the sorting fixture clamps a group of products including the damaged products and leaves the main marshaling conveyor line, the clamping piece group corresponding to the damaged products in the sorting fixture is released, and the damaged products are thrown into the designated area, and then the sorting fixture puts the remaining intact products on the brick collection conveyor line on one side of the main marshaling conveyor line;

[0034] Step 2: The brick collection conveyor line conveys the products to the sorting and grouping conveyor line, and the gaps between the products are eliminated by starting and stopping the brick collection conveyor line and the sorting and grouping conveyor line, and the products are grouped;

[0035] Step three, the palletizing device clamps the product group on the sorting and grouping conveyor line and puts it on the packaging conveyor line to wait for packaging, or the palletizing device places the clamped product group on the brick separation platform, and the brick separation platform reserves a forklift hole in the product group.
