Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board production, and in particular to a device and method for selecting defective gypsum boards. Background Art

[0002] During the production process of gypsum boards on the assembly line, cracks, breakages and other defects may appear on the gypsum boards on the production line during the process of cutting, turning over and re-slitting the gypsum boards. These defective gypsum boards cannot be picked out immediately on the production line because the production line is in continuous operation. They can only be sprayed with paint with obvious colors on the edges of the defective gypsum boards during the quality inspection process. After the gypsum boards are stacked, the defective gypsum boards are picked out before they are packaged as a whole. Currently, the defective gypsum is picked out manually, and the good gypsum boards are lifted away one by one until the defective gypsum boards are picked out. In the process of manually lifting the boards, the good gypsum boards are easily lost due to their large area and poor toughness, and it requires at least four manpower. In order to solve this problem, we have designed a gypsum board defective board selection device of the present invention.

[0003] After searching, Chinese patent document CN115892638A, publication (announcement) date: 2023.04.04 discloses a fully automatic selection device and method for defective gypsum boards, including: a base; a rotating frame, which is rotatably arranged on the top of the base, and a receiving cavity is arranged inside it, and the receiving cavity runs through both ends of the rotating frame, and a board feeding entrance connected to the receiving cavity is provided on its side. When the board feeding entrance is facing sideways, it is a board feeding position, and when the board feeding entrance is facing upward, it is a selection position. The rotating frame can rotate back and forth between the board feeding position and the selection position; a top supporting and limiting mechanism, which includes a top supporting assembly and an adjustable limiting assembly; a driving mechanism, which is arranged at the bottom of the base, driving the base to rotate; a detection and selection mechanism, which is arranged at the end of the rotating frame, automatically detects and selects defective products in the gypsum board. Its characteristics are: the rotating frame realizes the conversion of the gypsum board between the horizontal state and the vertical state, the top supporting and limiting mechanism allows the gypsum board to be loosened after being erected, and the detection and selection mechanism automatically detects and selects defective gypsum boards, thereby improving the selection efficiency and reducing the labor intensity; its disadvantages are: when removing defective gypsum boards, this scheme extends a push block to push out the defective gypsum boards. During the pushing process, there are the following problems: first, multiple gypsum boards are stacked together, and when the gypsum boards are in a vertical state, there is a tendency for the gypsum boards to tilt to the left or right, which will cause the gypsum boards to tilt to the left or right. Multiple gypsum boards are squeezed together. Since the contact area between adjacent gypsum boards is large, the friction is also large. Due to the low hardness of the gypsum boards, it is not easy to push them out by the push block; second, since the inclination angle of the gypsum boards is not fixed, the push block is not easy to align with the defective gypsum boards, and it will also cause damage to the adjacent gypsum boards.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] It should be noted that references in the specification to "this embodiment," "an embodiment," "an exemplary embodiment," "some embodiments," etc. indicate that the described embodiment may include a particular feature, structure, or characteristic, but not necessarily every embodiment includes that particular feature, structure, or characteristic. Furthermore, when a particular feature, structure, or characteristic is described in conjunction with an embodiment, it would be within the knowledge of those skilled in the relevant art to implement such feature, structure, or characteristic in conjunction with other embodiments (whether or not explicitly described).

[0035] Example 1: See also Figure 1-15A gypsum board defective board selection device includes a driving base 10 and a turning frame 20 rotatably mounted on the driving base 10. The turning frame 20 is radially provided with a placement groove 201. The groove bottom 202 of the placement groove 201 is installed with a support base 40. The support base 40 is provided with a plurality of slide grooves 41. A board separation device 70 is installed in the slide groove 41. The board separation device 70 includes a transverse block 71 and an inclined slider 72. The transverse block 71 is slidably mounted in the slide groove 41, and the inclined slider 72 is slidably mounted on the top of the transverse block 71. A first push rod device 42 is installed on the outside of the support seat 40 at a position corresponding to the slide groove 41. The telescopic end of the first push rod device 42 is connected to the transverse block 71. A second push rod device 73 is installed on the transverse block 71. The telescopic end of the second push rod device 73 is connected to the inclined sliding block 72. The transverse block 71 and the inclined sliding block 72 are matched through an inclined surface; a pushing device 80 is installed on the flip frame 20 at the second side surface 204 located in the placement groove 201. When the pushing device 80 is extended, it is used to push the first part of the gypsum board 91.

[0036] The driving base 10 is used to drive the flip frame 20 to rotate. A placement groove 201 is provided on the flip frame 20. The gypsum board group 90 is placed through the placement groove 201. The board separation device 70 is used to separate the gypsum board on the side of the defective gypsum board in the gypsum board group 90 into a first part 91 and a second part 92. The pushing device 80 is used to support the first part 91. When the flip frame 20 rotates counterclockwise, the first part 91 and the second part 92 are completely separated, thereby facilitating the removal of the defective gypsum board.

[0037] Specifically, see Figure 7 The first push rod assembly 42 is used to reciprocate the traverse block 71, while the second push rod assembly 73 is used to reciprocate the slanted slider 72. When the first push rod assembly 42 extends and the second push rod assembly 73 is stationary, the traverse block 71 and slanted slider 72 move rightward; conversely, they move leftward. When the first push rod assembly 42 extends and the second push rod assembly 73 extends synchronously and at the same speed, the traverse block 71 moves rightward while the slanted slider 72 remains in its original position. However, the slanted slider 72 rises, thereby lifting a portion 91.

[0038] In this embodiment, the first push rod device 42 and the second push rod device 73 can be electric push rods or electric cylinders, which can accurately control the speed and stroke.

[0039] See also Figure 6 、 7The end of the transverse block 71 near the first push rod assembly 42 is provided with a receiving cavity 711. A connecting hole 712 is provided on the side of the transverse block 71 located on the first push rod assembly 42. The telescopic end of the first push rod assembly 42 is fixedly connected to the transverse block 71 through the connecting hole 712. A hinge seat 723 is fixedly attached to the underside of the inclined slider 72. The hinge seat 723 extends into the receiving cavity 711. The fixed end of the second push rod assembly 73 is hingedly mounted in the receiving cavity 711, and the telescopic end of the second push rod assembly 73 is hingedly connected to the hinge seat 723. Through the above structure, the first push rod assembly 42 is installed.

[0040] Specifically, in this embodiment, see Figure 6 、 7 The end of the transverse moving block 71 close to the first push rod device 42 is higher than the end away from the first push rod device 42, and the end of the inclined sliding block 72 close to the first push rod device 42 is lower than the end away from the first push rod device 42. The transverse moving block 71 and the inclined sliding block 72 are slidably connected by the dovetail sliding block 722 and the dovetail slide groove 713. The bottom surface of the transverse moving block 71 is parallel to the top surface of the inclined sliding block 72; when the second push rod device 73 drives the inclined sliding block 72 to move toward the side close to the first push rod device 42, the top surface of the inclined sliding block 72 gradually rises above the support seat 40.

[0041] exist Figure 6 In the figure, the bottom inclined surface of the inclined slider 72 is provided with a dovetail slider 722, and the top inclined surface of the transverse block 71 is provided with a dovetail chute 713. The transverse block 71 can also be slidably installed at the bottom of the chute 41 through the dovetail slider and dovetail chute structure.

[0042] Further, see Figure 6 、 7 The inclined slider 72 is provided with an insert block 721 at the top of the first push rod device 42. The insert block 721 is a plate with a pointed tip at the top end, which is used to be inserted between the gypsum boards to prevent Figure 15 In the state shown, the lower end of the first portion of the gypsum board 91 slides down due to insufficient friction between the lower end of the first portion of the gypsum board 91 and the inclined slider 72 .

[0043] In this embodiment, see Figure 1 、 2The driving base 10 includes a base 11 and a driving wheel group and a driven wheel group installed on the base 11. The driving wheel group and the driven wheel group each include a rotating shaft 13 and a single-sided track wheel 14. The two ends of the rotating shaft 13 are respectively installed with bearing seats 12, and the bearing seats 12 are installed on the base 11. The rotating shaft 13 is also fixedly installed with single-sided track wheels 14 on the inner sides of the bearing seats 12 at both ends. The turning frame 20 is supported on the single-sided track wheels 14 of the driving wheel group and the driven wheel; one end of the rotating shaft 13 of the driving wheel group is connected to the reduction motor 16 for transmission, and the reduction motor 16 drives the driving wheel group to rotate, thereby driving the turning frame 20 to rotate. Figure 1 A driven wheel 15 is mounted on one end of the rotating shaft 13 of the driving wheel assembly, and a driving wheel 17 is mounted on the output shaft of the reduction motor 16. The driving wheel 17 and the driven wheel 15 are connected to each other through a belt or chain 18. When the driving wheel 17 and the driven wheel 15 are sprockets, a chain is used; when the driving wheel 17 and the driven wheel 15 are pulleys, a belt is used; wherein the pulley includes a synchronous pulley, and the belt includes a synchronous belt.

[0044] See also Figure 1 、 2 The flip frame 20 includes two circular plates 21 , which are connected and fixed by a connecting rod 22 . The two circular plates 21 are radially provided with notches to form a placement groove 201 .

[0045] In this embodiment, the connecting rod 22 is made of channel steel, and the connecting rods 22 at different positions are also used to install the third push rod device 60, the pushing device 80 and the sliding assembly 30.

[0046] See also Figure 1 、 2 4. The pushing device 80 includes a fourth push rod assembly 82, a pushing block 83, and a guide rod 84. The fixed end of the fourth push rod assembly 82 is mounted on the flip frame 20, and the telescopic end of the fourth push rod assembly 82 faces the first side surface 203 of the placement slot 201. The telescopic end of the fourth push rod assembly 82 is mounted to the pushing block 83. Guide rods 84 are mounted on one or both sides of the pushing block 83, and the guide rods 84 are slidably connected to the flip frame 20. The pushing block 83 includes a connecting block 831, which is connected to the telescopic end of the fourth push rod assembly 82. A guide plate 832 is provided on the side of the connecting block 831 away from the fourth push rod assembly 82. A pushing portion 833 is provided on the lower side of the guide plate 832. The guide rod 84 limits the pushing block 83, preventing it from rotating. The extension and contraction of the fourth push rod device 82 drives the push block 83 to extend and contract, and the area below the guide plate 832 and in front of the push portion 833 is used to support the first part of the gypsum board 91. Figure 15 The fourth push rod device 82 can be a pneumatic cylinder.

[0047] In this embodiment, see Figure 1 、 2 4. A fixing seat 81 is welded on the corresponding connecting rod 22, the fourth push rod device 82 is installed on the fixing seat 81, and the guide rod 84 is slidably matched with the fixing seat 81.

[0048] Example 2: Based on Example 1, see Figure 1 、 2 The tilting frame 20 is mounted with multiple sliding assemblies 30 on the first side 203 of the placement slot 201. The sliding assemblies 30 include brackets 31, axles 32, and rollers 33. The multiple rollers 33 are rotatably mounted within the brackets 31 via the axles 32. The sliding assemblies 30 allow the gypsum board set 90 to be flexibly moved on the first side 203, facilitating loading and unloading.

[0049] Example 3: On the basis of Example 1 or Example 2, see Figure 3 The support seat 40 is slidably mounted on the bottom 202 of the placement groove 201. A material blocking member 50 is fixedly mounted on the side of the support seat 40 close to the pushing device 80. The flip frame 20 is installed with a third push rod device 60 on the lower side of the groove bottom 202. The telescopic end of the third push rod device 60 is connected to the support seat 40 to drive the support seat 40 to move back and forth, so that it can adapt to the thickness of different gypsum board groups 90 according to different packaging requirements.

[0050] The third push rod device 60 can be an electric push rod or an electric cylinder.

[0051] See also Figure 4 When the third push rod device 60 is extended, the support seat 40 moves to the left, and the distance between the blocking member 50 and the first side surface 203 increases. Conversely, the distance decreases.

[0052] In addition, the support base 40 can adjust its position and reduce the collision between the gypsum board group 90 and the placement groove 201 when the gypsum board group 90 is turned over. Figure 3 、 4 As shown. Figure 3 When the support base 40 is in the state, the gypsum board group 90 can be clamped by the material blocking member 50, and then turned counterclockwise. Figure 4 In the state shown, the support base 40 is moving outward, causing the gypsum board set 90 to slowly move downward following the blocking member 50 .

[0053] In this embodiment, the material stopper 50 may be Figure 5 The multiple baffles may also be a whole baffle.

[0054] Specifically, see Figure 3The flip frame 20 is respectively installed with fixed supporting plates 23 on the two opposite sides below the groove bottom 202. The support seat 40 is slidably mounted in the flip frame 20, and the two ends of the support seat 40 are respectively connected with the supporting plates 23 on both sides in a sliding manner.

[0055] Example 4: On the basis of Example 1, Example 2, or Example 3, the present invention further proposes a method for selecting defective gypsum boards, which uses a device for selecting defective gypsum boards. The selection method includes the following steps: S1, see Figure 8 In the initial state of the selection device, a gypsum board set 90 consisting of multiple gypsum boards stacked together is placed on the first side 203 of the placement groove 201. In the initial state, the placement groove 201 of the turning frame 20 faces one side, the first side 203 of the placement groove 201 is located at the bottom, and the first side 203 is in a horizontal position.

[0056] S2, see Figure 9 The driving base 10 drives the flip frame 20 to rotate slowly counterclockwise, and the gypsum board group 90 slides along the first side 203 until the gypsum board group 90 abuts against the support base 40. Figure 10 shown.

[0057] S3, see Figure 11 When the placement slot 201 is facing upward, it is further rotated counterclockwise by an angle so that the gypsum board set 90 is completely against the side of the second side 204. When the support base 40 is provided with a stopper 50, the gypsum board set 90 is completely against the stopper 50.

[0058] S4, see Figure 12 The driving base 10 drives the flip frame 20 to rotate slowly clockwise by an angle so that the upper end of the gypsum board group 90 abuts against the first side surface 203, and then the flip frame 20 rotates so that the bottom 202 of the groove is in a horizontal state. Figure 13 shown.

[0059] S5, see Figure 13The first push rod assembly 42 moves the panel separator 70 toward the second side surface 204 until the front end of the inclined slider 72 moves to a position below a gypsum board adjacent to the defective gypsum board. At this point, the inclined slider 72 is still below the top surface of the support base 40. The second push rod assembly 73 then pushes the inclined slider 72 to the left. Simultaneously, the first push rod assembly 42 pushes the transverse block 71 to the right at the same speed. The top surface of the inclined slider 72 gradually rises, thereby completely lifting the first section of gypsum board 91 located to the right of the defective gypsum board. After lifting, the second push rod assembly 73 stops, and the first push rod assembly 42 pushes the transverse block 71 to continue moving to the right until the first section of gypsum board 91 is in a vertical position. At this point, the top of the first section of gypsum board 91 is approximately 15 mm higher than the second section of gypsum board 92 on the left.

[0060] When the oblique sliding block 72 is provided with an insert block 721, the insert block 721 is inserted between the defective gypsum board and the right gypsum board. The position of the defective gypsum board is determined by the previous paint mark.

[0061] S6, after that, see Figure 14 The pushing device 80 extends and supports the top of the first part of the gypsum board 91 through the pushing portion 833.
