Description

Technical Field

[0001] The utility model relates to the technical field of intelligent sorting, in particular to a device for intelligent sorting of length and surface quality of passive green building door and window materials. Background Art

[0002] Passive green building doors and windows are deeply loved by consumers due to their superior thermal insulation performance and environmental protection characteristics. Therefore, the production demand for passive green building door and window materials has also been increasing in recent years.

[0003] The pre-processing process of passive green building door and window materials includes: cutting the wood according to the length given in the order, slicing the wood surface through a four-sided slicer, and manually sorting the obtained wood according to length. The reason for sorting the wood according to length is that the subsequent process is the tenoning of the ends of the wood. In order to improve the processing efficiency, workers usually process two pieces of wood at the same time. At this time, if the length of the two pieces of wood is very different, it will be inconvenient for the workers to hold them. In addition, due to the length difference during processing, the processing stability is relatively poor. Therefore, workers need to sort the wood according to length first, and then perform the tenoning of the ends of the wood.

[0004] However, since planing processing is currently generally carried out by machine tools with high efficiency, when wood is currently sorted manually, it is impossible to measure the length of each piece of wood due to the need to keep up with the progress of planing processing and the requirements of time and efficiency. Most of the time, wood can only be sorted by length based on experience, resulting in poor sorting effect. In addition, it is difficult to effectively screen out wood with unqualified surface quality during the rapid sorting process, resulting in the length size differences and surface quality of the sorted wood being difficult to meet subsequent processing requirements, seriously affecting the processing efficiency and quality of the wood end mortising.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1 As shown, a passive green building door and window material length and surface quality intelligent sorting device includes a sorting mechanism 1 and an electric roller table 102, wherein the electric roller table 102 uses a feeding roller table to transfer the wood 100 from the outside to the sorting mechanism 1. Preferably, in order to facilitate the sorting of the long and short wood 100 identified by the sorting mechanism 1 in different directions, and to remove the unqualified wood 100, the number of electric roller tables 102 can be increased, and a total of four electric roller tables 102 are arranged in a cross shape around the sorting mechanism 1. Except for the feeding roller table, the other three electric roller tables 102 all use a discharge roller table to transfer the wood 100 from the sorting mechanism 1 to the outside. In addition, in order to facilitate the feeding roller table to effectively feed the wood 100 into the sorting mechanism 1, a closing device 101 can be fixedly arranged on the surface of the feeding roller table to guide the wood 100 to the accommodating cavity of the cross rotating frame 1-5.

[0022] Combination Figure 2-3As shown, the sorting mechanism 1 includes an upper cover 1-1, a cross rotating frame 1-5, a base 1-6 and four sorter assemblies 1-4. A circular table is provided on the top of the base 1-6 and a cylindrical protrusion is integrally provided at the center of its surface. The cross rotating frame 1-5 is provided with a center hole and is rotatably mounted on the cylindrical protrusion. The four arms of the cross rotating frame 1-5 are respectively provided with accommodating cavities, and the accommodating cavities are connected with the upper and lower surfaces and the outer ends of the arms.

The servo motor 1-7 is fixed on the lower surface of the upper cover 1-1 and a gear 1-8 is fixed on its output shaft. The gear 1-8 is meshed with the annular tooth. The servo motor 1-7 drives the cross rotating frame 1-5 to rotate through the gear 1-8 and the annular tooth. In addition, other conventional transmission forms that can realize the servo motor 1-7 driving and controlling the cross rotating frame 1-5 to rotate belong to the above-mentioned structure and other means of replacement, and should also fall within the protection scope of this application. The upper cover 1-1 adopts a circular plate coaxially fixed to the top of the cylindrical protrusion through the second screw group 1-3, and the four sorter assemblies 1-4 are respectively arranged radially on the lower surface of the upper cover 1-1 and are arranged one by one above the four arms of the cross rotating frame 1-5. It is also worth mentioning that since the four sorter assemblies 1-4 of the sorting mechanism 1 are also arranged in a cross shape, the servo motor 1-7 can set the single rotation angle to 90° when controlling the rotation of the cross rotating frame 1-5. This part can be achieved by encoding the servo motor 1-7, which is an existing conventional motor control method.

[0023] Combination Figure 4 As shown, the sorter assembly 1-4 includes a U-shaped shell sheet metal 1-4-1, a transmission shaft 1-4-6, a drive motor 1-4-7 and a plurality of single-group sorters 1-4-5.

[0024] Combination Figure 5-6As shown, each single-group sorter 1-4-5 is provided with a straight partition sheet metal 1-4-5-11 which is radially fixed to the lower surface of the upper cover 1-1 by a first screw group 1-2, and a plurality of fixing plates 1-4-5-9 are provided on one side wall of the straight partition sheet metal 1-4-5-11 along the length direction, and a pin shaft 1-4-5-8 is vertically fixed on the top of the fixing plate 1-4-5-9, and the pin shaft 1-4-5-8 is hinged to the corner point of the V-shaped steering rod 1-4-5-7, and each of the V-shaped steering rods 1-4-5-7 is opened downward and a universal ball 1-4-5-3 and a swing plate 1-4-5-2 are respectively provided at the bottom of its two end points. The universal ball 1-4-5-3 is hinged to the corresponding end of the V-shaped steering rod 1-4-5-7, and the pressure sensor 1-4-5-5 is connected to the upper surface of the universal ball 1-4-5-3 through the spring 1-4-5-4, and the pressure sensor 1-4-5-5 is fixed on the lower surface of the upper cover 1-1. The swing plate 1-4-5-2 adopts a cam configuration and its swing end edge is hinged to the corresponding end of the V-shaped steering rod 1-4-5-7. The roller shaft 1-4-5-13 is rotatably set through the middle position of the swing end of the swing plate 1-4-5-2. The outer end of the roller shaft 1-4-5-13 is coaxially fixed with the roller 1-4-5-1. The roller 1-4-5-1 is preferably provided with an anti-skid rubber layer on the circumferential surface to increase the friction with the wood 100 so as to more stably drive the wood 100 to move in the accommodating cavity of the cross rotating frame 1-5. A sprocket shaft 1-4-5-12 is vertically rotated at the bottom of the fixed plate 1-4-5-9, one end of the sprocket shaft 1-4-5-12 is rotatably connected to the rotation center of the swing plate 1-4-5-2, and at the same time, one end of the sprocket shaft 1-4-5-12 is connected to the inner end of the roller shaft 1-4-5-13 through a belt drive assembly 1-4-5-10, and the other end of the sprocket shaft 1-4-5-12 passes through the straight partition sheet metal 1-4-5-11 to coaxially fix the driven sprocket 1-4-5-6.

[0025] Combination Figure 4 As shown, the multiple driven sprockets 1-4-5-6 of each single-group sorter 1-4-5 are connected for transmission with the corresponding driving sprocket 1-4-4 on the transmission shaft 1-4-6 through the chain 1-4-3, and the transmission shaft 1-4-6 is driven to rotate by the driving motor 1-4-7. The driving sprocket 1-4-4 on the transmission shaft 1-4-6 can drive the driven sprockets 1-4-5-6 of all the single-group sorters 1-4-5 to rotate through the chain 1-4-3, thereby driving the roller 1-4-5-1 to rotate through the transmission chain of the sprocket shaft 1-4-5-12, the belt drive assembly 1-4-5-10, and the roller shaft 1-4-5-13. The forward and reverse rotation of the driving motor 1-4-7 can control the forward and reverse rotation of all the rollers 1-4-5-1, thereby realizing the inward and outward movement of the wood 100 in the accommodating cavity of the cross rotating frame 1-5 when the roller 1-4-5-1 compacts the wood 100.

[0026] Combination Figure 7 As shown, the bottom end of the U-shaped shell sheet metal 1-4-1 is a plane configuration, and the bottom end of the U-shaped shell sheet metal 1-4-1 and the corresponding positions of all the rollers 1-4-5-1 and the universal ball 1-4-5-3 are respectively processed with extension openings to allow the rollers 1-4-5-1 and the universal ball 1-4-5-3 to extend out of the bottom end of the U-shaped shell sheet metal 1-4-1 and contact the wood 100.

[0027] The working principle of the intelligent sorting device is as follows: the wood 100 is sent to the sorting mechanism 1 by the electric roller table 102 serving as a feeding roller table. Under the action of the closing device 101, the wood 100 can better move along the center of the cross rotating frame 1-5 to enter the accommodating cavity. When the end of the wood 100 just enters the accommodating cavity, it will lift up a row of universal balls 1-4-5-3 located at the outer end and perpendicular to the movement direction of the wood 100 in the sorting device assembly 1-4 above it. Under the action of the V-shaped steering rod 1-4-5-7, the swing end of the corresponding swing plate 1-4-5-2 deflects downward, so that the corresponding roller 1-4-5-1 is pressed down and contacts with the upper surface of the end of the wood 100. At this time, the driving motor 1-4-7 is started to drive the transmission shaft 1-4-6 to rotate, and the active sprocket 1-4-4 corresponding to the single group sorter 1-4-5 on it rotates accordingly, and under the action of the chain 1-4-3, it can bring All driven sprockets 1-4-5-6 are driven to rotate, and then all rollers 1-4-5-1 are driven to rotate through the belt drive assembly 1-4-5-10, until the wood 100 is completely moved into the accommodating cavity of the cross rotating frame 1-5 under the rotation and friction of the rollers 1-4-5-1, and then the driving motor 1-4-7 stops rotating. According to the length of the wood 100, the number of universal balls 1-4-5-3 lifted up in the sorter assembly 1-4 is also different. The lifted universal balls 1-4-5-3 will compress the spring 1-4-5-4 above it, thereby triggering the corresponding pressure sensors 1-4-5-5. The approximate length of the wood 100 can be calculated according to the number of triggered pressure sensors 1-4-5-5. Although accurate measurement cannot be achieved, it is only necessary to sort the wood into two types of length as needed, and only the approximate length size is needed for practical use.If the wood 100 is a long wood, the servo motor 1-7 is started to control the cross rotating frame 1-5 to rotate to one of the electric roller tables 102 serving as the discharge roller table (for example, rotate 90° clockwise), and the drive motor 1-4-7 in the side sorter assembly 1-4 is started to rotate in the opposite direction, so that the wood 100 is discharged outward from the accommodating cavity of the cross rotating frame 1-5 by the reverse rotation of the roller 1-4-5-1, until the wood 100 is completely discharged and then transported to the long wood storage location through the discharge roller table; if the wood 100 is a short wood, the servo motor 1-7 is started to control the cross rotating frame 1-5 to rotate to another electric roller table 102 serving as the discharge roller table (for example, rotate 90° counterclockwise), and the drive motor 1-4-7 in the side sorter assembly 1-4 is started to rotate in the opposite direction, so that the wood 100 is discharged outward from the accommodating cavity of the cross rotating frame 1-5 by the reverse rotation of the roller 1-4-5-1, until the wood 100 is completely discharged and then transported to the long wood storage location through the discharge roller table. After the wood 100 is completely discharged, it can be transferred to the short wood storage location through the discharge roller table; if there are defects on the surface of the wood 100 or the flatness error is large, the compression amount of the spring 1-4-5-4 corresponding to the jacked-up universal ball 1-4-5-3 will also be greatly different, resulting in a large difference in the value of the corresponding pressure sensor 1-4-5-5. At this time, it can be used as an auxiliary means to determine that the wood 100 is unqualified, and then the servo motor 1-7 is started to control the cross rotating frame 1-5 to rotate to the last electric roller table 102 as the discharge roller table (for example, rotate 180° clockwise / counterclockwise), and the drive motor 1-4-7 in the side sorter assembly 1-4 is started to rotate in the opposite direction, so that the wood 100 is discharged from the accommodating cavity of the cross rotating frame 1-5 to the outside through the reverse rotation of the roller 1-4-5-1, until the wood 100 is completely discharged, it can be transferred to the defective wood storage location through the discharge roller table, so as to remove the defective wood.
