Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of automated glass production, and in particular to a breaking assembly and a cross-cutting machine. Background Art
[0002] In the overflow process of glass production, the vertically flowing glass liquid will gradually cool and solidify to form a continuous glass ribbon. According to production requirements, this continuous glass ribbon needs to be cut into glass blocks of specific sizes to facilitate subsequent processing.
[0003] In the prior art, the robot's breaking arm is first used to absorb the lower end of the glass ribbon and descend synchronously with the glass ribbon; then it is cut by a cross-cutting machine, and the mounting frame on the cross-cutting machine drives the knife wheel mechanism to descend synchronously with the glass ribbon. During the descent of the knife wheel mechanism, a horizontal line is simultaneously drawn along the width direction of the glass ribbon, so that the glass ribbon forms a score line of a certain depth, and finally the glass ribbon is broken by the breaking arm to form a glass block.
[0004] However, in the process of realizing the invention, the inventors found that when the width of the glass ribbon exceeds a certain limit (for example, more than 2 meters), the glass ribbon will produce a certain arc deformation. The existence of this arc makes it difficult to evenly distribute the force applied to the glass ribbon by the breaking arm, thereby causing the glass block to break during the breaking step.

The mounting groove is threadedly connected to the connecting rod, and the mounting groove and the connecting rod together form the second locking member.
[0019] In some embodiments, the second locking member further includes a second nut, the second nut is threadedly connected to the connecting rod, and the second nut is used to abut against the second end surface of the telescopic rod.

[0041] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0042] In the process of producing glass by overflow method, the continuous glass ribbon needs to be cut into pieces to facilitate further processing. The inventor noticed that in the process of cutting the glass ribbon, in order to avoid the problem of stress concentration caused by the cross-cutting machine cutting the entire glass ribbon at one time, which causes the glass to break, the industry currently uses robots and cross-cutting machines to work together, with the robot's breaking arm completing the adsorption and breaking actions, and the cross-cutting machine completing the marking action. The cross-cutting machine first marks the preset depth, and then breaks the glass with the breaking arm to disperse the stress and reduce the possibility of breakage caused by uneven stress.
[0043] However, the inventors have noticed that in the actual production process, the width of the glass ribbon varies according to production requirements. When the width of the glass ribbon exceeds a certain limit, the glass ribbon will produce a certain arc deformation. Since multiple suction cups are arranged on the breaking arm, this arc deformation may cause one or some of the suction cups to adsorb poorly, resulting in the force applied to the glass ribbon by the breaking arm during the breaking process cannot be evenly distributed, thereby causing the glass to break during the breaking step.
[0044] After in-depth research, the applicant found that a breaking assembly 100 can be added to the mounting frame 200 of the original cross-cutting machine, and the roller 3 of the breaking assembly 100 is in rolling contact with the glass ribbon 7 to be cut. The roller 3 cooperates with the knife wheel mechanism 300 to complete the initial and accurate breaking during the marking process, thereby reducing the force required for the subsequent breaking arm to break, thereby reducing the problem of breakage caused by the breaking arm during the breaking process; at the same time, the telescopic rod 1 and the spring 4 of the breaking assembly 100 are used to absorb the force generated by the slight deformation of the glass ribbon, thereby avoiding excessive force applied by the roller 3 to the glass ribbon 7 to be cut, thereby causing breakage.
[0045] Example 1
[0046] like Figure 1 and Figure 2 As shown, Embodiment 1 of the present application provides a breaking assembly 100, comprising: a telescopic rod 1, a fixing portion 2, a roller 3 and a spring 4;
[0047] The first end of the telescopic rod 1 is used to be connected to the mounting frame 200 of the cross-cutting machine, and the telescopic rod 1 is used to be spaced apart from the cutter wheel mechanism 300 of the cross-cutting machine;
[0048] The fixing portion 2 is connected to the second end of the telescopic rod 1 along a first side of a first direction A;
[0049] The roller 3 is connected to the second side of the fixing part 2 along the first direction A by rotating around the second direction B, and the roller 3 is used for rolling contact with the glass ribbon 7 to be cut, and the roller 3 is used for applying force to the glass ribbon 7 to be cut; the first direction A is the thickness direction of the glass ribbon 7 to be cut, and the second direction B is the length direction of the glass ribbon 7 to be cut;
[0050] The spring 4 is sleeved on the telescopic rod 1 , and the spring 4 is used to be arranged between the mounting bracket 200 and the fixing portion 2 .
[0051] Specifically, the telescopic rod 1 ensures that the entire breaking assembly 100 can be stably mounted on the mounting frame 200. The telescopic rod 1 can be telescopic along the first direction A. The first end of the telescopic rod 1 can be fixedly connected to the mounting frame 200, for example, by a pin or a flange, so as to achieve a stable connection between the telescopic rod 1 and the mounting frame 200, indirectly ensuring that the roller 3 always rotates stably around the second direction B, thereby enabling the roller 3 to accurately control the direction and magnitude of the force applied to the glass ribbon 7 to be cut, thereby ensuring the breaking effect of the breaking assembly 100 and reducing the occurrence of glass breakage and irregular cracks.
[0052] The telescopic rod 1 and the cutter wheel mechanism 300 are arranged on the mounting frame 200 at intervals. The specific connection method between the cutter wheel mechanism 300 and the mounting frame 200 is known to those skilled in the art and will not be described here. During operation, the cutter wheel mechanism 300 and the breaking assembly 100 move synchronously along the third direction C and the second direction B with the mounting frame 200. When the breaking assembly 100 is installed, the other end of the telescopic rod 1 is located on the first side of the third direction C of the cutter wheel mechanism 300, and the telescopic rod 1 is located on one side of the cutter wheel mechanism 300 along the second direction B, so that after the cutter wheel mechanism 300 completes the scribing operation of the glass ribbon 7 to be cut, the roller 3 can quickly and accurately act on the scribing area to perform local pre-snapping, thereby achieving a preliminary and accurate breaking action to reduce the stress concentration and the risk of fragmentation that may occur in the subsequent overall breaking process.
[0053] The fixing portion 2 can cooperate with the mounting frame 200 to constrain the spring 4 sleeved on the telescopic rod 1. The fixing portion 2 can be fixedly connected to the second end of the telescopic rod 1 by riveting or bolting, so as to achieve a stable connection between the telescopic rod 1 and the fixing portion 2, and indirectly ensure that the roller 3 always rotates stably around the second direction B; or, the second end of the telescopic rod 1 extends radially to form the fixing portion 2.
[0054] The roller 3 is used to apply force to the glass ribbon 7 to be cut. The force applied by the roller 3 to the glass to be cut can be adaptively adjusted based on the material, thickness and width of the glass, and the force applied by the roller 3 to the glass ribbon 7 to be cut can be adjusted by the length of the telescopic rod 1 and the length of the spring 4.
[0055] Since the glass ribbon 7 to be cut has a relatively high temperature, a layer of heat-resistant rubber may be attached to the outside of the roller 3 , and the roller 3 is in rolling contact with the glass ribbon 7 to be cut via the heat-resistant rubber, so as to extend the service life of the roller 3 .
[0056] The spring 4 plays the role of elastic support and buffer, and can adapt to the slight deformation of the glass ribbon 7 to be cut. In order to constrain the spring 4 on the telescopic rod 1, the spring 4 is arranged between the mounting frame 200 and the fixing part 2 at both ends of the telescopic rod 1, and the mounting frame 200 and the fixing part 2 can limit the spring 4 from sliding out of the telescopic rod 1. The two ends of the spring 4 may not be connected to the mounting frame 200 and the fixing part 2; or, one end of the spring 4 is connected to the mounting frame 200; or, one end of the spring 4 is connected to the fixing part 2; or, the two ends of the spring 4 are respectively connected to the mounting frame 200 and the fixing part 2.
[0057] Through the above technical solution, the breaking assembly provided by the present disclosure arranges the first end of the telescopic rod 1 and the cutter wheel mechanism 300 at intervals on the mounting frame 200, ensuring that the telescopic rod 1 can move synchronously with the mounting frame 200 during the cutting process and does not interfere with the cutter wheel mechanism 300, thereby ensuring the accurate cutting and breaking operations;
[0058] The first side of the fixing portion 2 is connected to the second end of the telescopic rod 1, and the fixing portion 2 effectively constrains the spring 4 sleeved on the telescopic rod 1, preventing the spring 4 from sliding out of the second end of the telescopic rod 1, and ensuring that the spring 4 can be telescopically adjusted between the fixing portion 2 and the mounting frame 200; during the cutting and breaking process, the spring 4 plays a role of elastic support and buffering, and the spring 4 absorbs part of the force generated by the slight deformation of the glass ribbon, preventing the roller 3 from applying too much force to the glass ribbon 7 to be cut and causing it to break, thereby improving the product yield rate;
[0059] The roller 3 is connected to the second side of the fixing portion 2 by rotating around the second direction B. When the roller 3 is in rolling contact with the glass to be cut, it can evenly and appropriately apply force to the local glass ribbon 7 to be cut. The force applied by the roller 3 works in coordination with the marking action of the cutter wheel mechanism 300, so that the roller 3 can cooperate with the cutter wheel mechanism 300 to complete the initial and precise breaking during the marking process, which significantly reduces the force required for the subsequent breaking arm to break, thereby reducing the problem of breakage caused by the breaking arm during the breaking process.
[0060] In order to make the breaking assembly 100 applicable to glass ribbons 7 to be cut of different sizes, Figure 1 and Figure 2 As shown, in some embodiments, it also includes:
[0061] The first locking member 5, the first end of the telescopic rod 1 is used to be movably connected to the mounting frame 200 along the first direction A, the first locking member 5 is connected to the first end of the telescopic rod 1, and the first locking member 5 is used to limit the first end of the telescopic rod 1 from sliding along the first direction A.
[0062] Specifically, the force applied by the breaking assembly 100 to the glass ribbons 7 of different thicknesses can be adjusted by adjusting the spacing between the roller 3 and the mounting frame 200. The first end of the telescopic rod 1 can be slidably connected to the mounting frame 200 along the first direction A. At this time, the mounting frame 200 has a mounting hole along the first direction A, and one end of the telescopic rod 1 extends into the mounting hole and slides along the first direction A in the mounting hole.
[0063] The first locking member 5 may include a bracket and a screw; the bracket is fixedly arranged on the mounting frame 200, and the bracket has a threaded hole, and the screw can be screwed in and out of the threaded hole. When the screw is screwed into the threaded hole, it can abut against the side wall of the first end of the telescopic rod 1, and limit the first end of the telescopic rod 1 from sliding along the first direction A; when the screw is screwed out of the threaded hole, the first end of the telescopic rod 1 can slide along the first direction A. The mounting hole on the mounting frame 200 can be a through hole, and the first locking member 5 can be located on one side or the other side of the mounting frame 200 along the first direction A; or, the mounting hole can also be a blind hole, and the first locking member 5 and the spring 4 are located on the same side of the mounting frame 200 along the first direction A; or,
[0064] like Figure 1 and Figure 2 As shown, in some embodiments, the first locking member 5 includes a first nut, and a first end of a portion of the telescopic rod 1 is used to extend out of the mounting bracket 200 and be threadedly connected to the first nut.
[0065] Specifically, the mounting hole is a through hole, the first end of the telescopic rod 1 has an external thread matching the first nut, and the first end of the telescopic rod 1 partially passes through the mounting frame 200 through the mounting hole. The first nut and the spring 4 are respectively located on both sides of the mounting frame 200 along the first direction A. When the first nut is screwed into the first end of the telescopic rod 1 and abuts against the mounting frame 200, the first nut can limit the first end of the telescopic rod 1 from sliding along the first direction A; when the first nut is screwed out of the first end of the telescopic rod 1, the first end of the telescopic rod 1 slides along the first direction A.
[0066] In order to enhance the limiting effect of the first nut, the first nut can be a locking nut with a top thread hole.
[0067] In some embodiments, it also includes:
[0068] A limiting portion (not shown in the figure) is arranged on the side wall of the first end of the telescopic rod 1; the limiting portion is used to be slidably connected to the mounting frame 200 along the first direction A, and the limiting portion is used to limit the rotation of the telescopic rod 1 around the first direction A.
[0069] Specifically, the mounting frame 200 further has a guide groove, which is connected to the mounting hole. The guide groove is in a strip shape and extends along the first direction A. The guide groove is used to guide the movement path of the first end of the telescopic rod 1 along the first direction A through the limiting portion. When the first end of the telescopic rod 1 is inserted into the mounting hole, the limiting portion is inserted into the guide groove to ensure that the telescopic rod 1 slides along the first direction A, and the telescopic rod 1 is restricted from rotating around the first direction A, which indirectly ensures that the roller 3 always rotates stably around the second direction B, thereby enabling the roller 3 to accurately control the direction and magnitude of the force applied to the glass ribbon, thereby ensuring the breaking effect of the breaking assembly 100.
[0070] In addition, the first end of the telescopic rod 1 can also be threadedly connected to the mounting frame 200, and the distance between the roller 3 and the mounting frame 200 bracket can be adjusted by screwing the first end of the telescopic rod 1 in and out. However, it should be noted that during adjustment, it is necessary to ensure that the roller 3 always rotates stably around the second direction B.
[0071] like Figure 1 and Figure 2 As shown, in some embodiments, it also includes:
[0072] The second locking piece 6, the first side of the fixed part 2 is movably connected to the second end of the telescopic rod 1 along the first direction A, the second locking piece 6 is connected to the first side of the fixed part 2 and / or the second end of the telescopic rod 1, and the second locking piece 6 is used to limit the movement of the fixed part 2 along the first direction A.
[0073] Specifically, the fixing part 2 and the second end of the telescopic rod 1 can be slidably connected along the first direction A. For example, the second end of the telescopic rod 1 is provided with a plurality of through-limiting holes at intervals along the first direction A. The second locking member 6 can be a bolt. The second locking member 6 extends into a limiting hole and abuts against the fixing part 2, that is, the fixing part 2 is restricted from moving relative to the second end of the telescopic rod 1 along the first direction A. Alternatively,
[0074] like Figure 1 and Figure 2 As shown, in some embodiments, the second end surface of a portion of the telescopic rod 1 is recessed inwardly along the first direction A to form a mounting groove with an internal thread, the first side of the fixing portion 2 extends outwardly along the first direction A to form a connecting rod with an external thread, the mounting groove is threadedly connected to the connecting rod, and the mounting groove and the connecting rod together form the second locking member 6. Or,
[0075] The second locking piece 6 is connected to the second end of the telescopic rod 1. At this time, the second end of the telescopic rod 1 can have an external thread. The first side of the fixing portion 2 is recessed inward along the first direction A to form a connecting hole with an internal thread. The second end of the telescopic rod 1 is threadedly connected to the connecting hole.
[0076] In order to enhance the locking effect of the second locking member 6, as Figure 1 and Figure 2 As shown, in some embodiments, the second locking member 6 further includes a second nut, the second nut is threadedly connected to the connecting rod, and the second nut is used to abut against the second end surface of the telescopic rod 1. In this case, the second nut can be used to limit the spring 4 from sliding out of the second end of the telescopic rod 1; or, the fixing portion 2 can include a first sub-fixing portion and a second sub-fixing portion, the first sub-fixing portion is arranged on the telescopic rod 1, and the first sub-fixing portion is arranged between the second nut and the mounting frame 200, and the first sub-fixing portion is used to limit the spring 4 from sliding out of the second end of the telescopic rod 1; the first side of the second sub-fixing portion extends outward to form a connecting rod with an external thread.
[0077] When the first end of the telescopic rod 1 is threadedly connected to the mounting frame 200, and the second end of the telescopic rod 1 is threadedly connected to the fixing portion 2, the pitches of the threads at both ends of the telescopic rod 1 can be different. By adjusting both ends at the same time, a more accurate adjustment effect can be obtained, and it can also be ensured that the roller 3 always rotates stably around the second direction B during adjustment.
[0078] like Figure 1 and Figure 2 As shown, in some embodiments, the second side of the fixing portion 2 is recessed inward along the first direction A to form a limiting groove, a portion of the roller 3 is accommodated in the limiting groove, the roller 3 is rotatably connected to the inner wall of the limiting groove around the second direction B, the roller 3 and the limiting groove are clearance-matched along the second direction B, and another portion of the roller 3 extends out of the limiting groove for rolling contact with the glass ribbon 7 to be cut.
[0079] Specifically, the limiting groove is used to ensure that the roller 3 always rotates stably around the second direction B.
[0080] Example 2
[0081] Embodiment 2 of the present application provides a cross-cutting machine, comprising:
[0082] Mounting frame 200;
[0083] A cutter wheel mechanism 300 is disposed on the mounting frame 200; and
[0084] In the breaking assembly 100 described in Example 1, the first end of the telescopic rod 1 of the breaking assembly 100 is connected to the mounting frame 200 , and the telescopic rod 1 is spaced apart from the cutter wheel mechanism 300 .
[0085] Through the above technical solution, the cross-cutting machine provided in Example 2 of the present disclosure includes the breaking assembly 100 of Example 1, and the breaking assembly 100 arranges the first end of the telescopic rod 1 and the knife wheel mechanism 300 on the mounting frame 200 at intervals, ensuring that the telescopic rod 1 can move synchronously with the mounting frame 200 during the cutting process and does not interfere with the knife wheel mechanism 300, thereby ensuring the accurate cutting and breaking operations;
[0086] The first side of the fixing portion 2 is connected to the second end of the telescopic rod 1, and the fixing portion 2 effectively constrains the spring 4 sleeved on the telescopic rod 1, preventing the spring 4 from sliding out of the second end of the telescopic rod 1, and ensuring that the spring 4 can be telescopically adjusted between the fixing portion 2 and the mounting frame 200; during the cutting and breaking process, the spring 4 plays a role of elastic support and buffering, and the spring 4 absorbs part of the force generated by the slight deformation of the glass ribbon 7 to be cut, thereby preventing the roller 3 from applying too much force to the glass ribbon to cause breakage, thereby improving the product yield rate;
[0087] The roller 3 is connected to the second side of the fixing portion 2 by rotating around the second direction B. When the roller 3 is in rolling contact with the glass to be cut, it can evenly and appropriately apply force to the local glass ribbon 7 to be cut. The force applied by the roller 3 works in coordination with the marking action of the cutter wheel mechanism 300, so that the roller 3 can cooperate with the cutter wheel mechanism 300 to complete the initial and precise breaking during the marking process, which significantly reduces the force required for the subsequent breaking arm to break, thereby reducing the problem of breakage caused by the breaking arm during the breaking process.
[0088] like Figure 1 As shown, in some embodiments, there are two breaking assemblies 100, and the two breaking assemblies 100 are respectively located on both sides of the cutter wheel mechanism 300 along the second direction B; and / or,
[0089] The two breaking assemblies 100 are both located on the first side of the cutter wheel mechanism 300 along the third direction C, which is the direction of the width of the glass ribbon 7 to be cut. The first side of the cutter wheel mechanism 300 along the third direction C is the side of the glass ribbon 7 to be cut that has been cut by the cutter wheel mechanism 300.
[0090] Specifically, the two breaking assemblies 100 enhance the breaking effect of the pre-breaking. The positions of the two breaking assemblies 100 and the cutter wheel mechanism 300 can be set according to the size and performance of the glass ribbon 7 to be cut. For example, the two breaking assemblies 100 are 50-70 mm away from the cutter wheel mechanism 300 along the third direction C, such as 50 mm, 60 mm or 70 mm, etc.; the two breaking assemblies 100 are 55-65 mm away from the cutter wheel mechanism 300 along the second direction B, such as 55 mm, 60 mm or 65 mm, etc., wherein 60 mm is preferred.
[0091] In addition, the cross-cutting machine also includes an anvil mechanism 400, which is directly opposite to the knife wheel mechanism 300. The structure of the anvil mechanism 400 is known to those skilled in the art and will not be described in detail here. The position where the roller 3 of the breaking component 100 rolls in contact with the glass ribbon 7 to be cut is the first contact position, and the position where the anvil mechanism 400 contacts the glass ribbon 7 to be cut is the second contact position. The distance between the first contact position and the second contact position is 5-8 mm, for example, 5 mm, 6 mm, 7 mm or 8 mm, to ensure the yield rate of the breaking component 100.
