Description

Technical Field

[0001] The invention relates to a stone cutting technology, in particular to a stone conveying and cutting machine. Background Art

[0002] Stone cutting equipment is a type of stone cutting machinery, which is used to cut stone into strips of required size horizontally and vertically. Traditional stone cutting uses a single knife, which is extremely inefficient. Currently, single knives are generally replaced with multiple knives, which improves efficiency, but there are still major shortcomings.

[0003] At present, there are two main methods for cutting stone strips. One is to cut horizontally and vertically separately, which requires multiple loading and unloading operations, which is cumbersome and inefficient. The other is to cut horizontally and vertically in one flow, first cutting horizontally into several intermediate plates, then conveying, turning, flipping, and connecting the intermediate plates one by one, and then cutting vertically. Although it saves the operation of loading and unloading in the middle, the series of operations in the middle to achieve the turning cutting not only greatly lengthens the entire cutting production line, but also complicates the operation, and requires high matching accuracy. The production efficiency is still not ideal, which affects the production benefits.

[0004] In view of this, this case conducts an in-depth study on the above-mentioned problems, innovatively proposes a stone cutting device, and accordingly proposes a stone conveying and cutting machine. Summary of the invention

[0034] The case is further described in detail below in conjunction with specific implementation methods.

[0035] This case involves a stone conveying and cutting machine. The first solution is as follows Figure 1-3 As shown, it includes a frame 100, a transport vehicle 200 and a saw blade cutting assembly 300.

[0036] The frame 100 is provided with a running rail 11, and the conveying vehicle 200 is movably mounted on the running rail 11 to realize back and forth conveying. The saw blade cutting assembly 300 is suspended on the frame 100 to cut the stone material on the conveying vehicle 200 below it.

[0037] The saw blade cutting assembly 300 can be any existing saw blade cutting assembly. One preferred method is to suspend the saw blade in a swing cutting manner. Specifically, the saw blade cutting assembly 300 includes a swing frame 31, a saw blade spindle box 32, and a saw blade drive assembly 33. The swing frame 31 is movably pivoted on the frame 100. A lifting cylinder group 34 is provided between the swing frame 31 and the frame 100 to drive the swing frame 31 to swing in coordination with the cutting operation. The saw blade spindle box 32 is mounted on the swing frame 31 and driven by the saw blade drive assembly 33 to realize the saw blade rotation cutting operation. The saw blade spindle box 32 can be driven by a single spindle as a whole, or by multiple spindles separately.

[0038] The transport vehicle 200 includes an upper frame 21 and a lower frame 22 that are movably assembled with each other. The lower frame 22 is provided with a strip plate group 221, which is composed of a plurality of strip plates that are parallel to each other and spaced apart and arranged side by side. The bottom of the lower frame 22 is provided with a running wheel group 222, which serves as the running and transporting wheel of the transport vehicle 200 and is mounted on the running rail 11 for running. The upper frame 21 is movably mounted on the lower frame 22. The upper frame 21 is provided with a vehicle-mounted roller group 211, which is composed of a plurality of rollers that are parallel to each other and spaced side by side. The plurality of rollers of the vehicle-mounted roller group 211 and the plurality of strips of the strip group 221 are staggered in the horizontal direction (preferably staggered one by one). In this way, when the height position of the upper frame 21 relative to the lower frame 22 is changed, the vehicle-mounted roller group 211 can be raised and lowered relative to the strip group 221, thereby realizing the relative height change adjustment of the two.

[0039] The scheme for changing the height position of the upper frame 21 relative to the lower frame 22 is that a support wheel set 212 is provided at the bottom of the upper frame 21, and the wheel travel direction of the support wheel set 212 and the running wheel set 222 are arranged in parallel, that is, the wheel axes of the support wheel set 212 and the running wheel set 222 are parallel to each other, so that during the movement and sliding of the running wheel set 222, the support wheel set 212 is also in a state of being able to slide. A support inclined plane set 12 is provided on the frame 100, corresponding to the position of the cutting operation area of ​​the staggered saw blade cutting assembly 300, and the purpose of the support inclined plane set 12 is to allow the support wheel set 212 to crawl on it, and to change the height of the support wheel set 212 by the slope of the inclined plane, so that the support wheel set 212 has a high and low support state, and finally realizes the vehicle-mounted roller set 211 to be higher or lower than the strip plate set 221. The adjustable lifting action.

[0040] The stone conveying and strip cutting machine in this case adopts an ingenious integrated operation mode of stone conveying and strip cutting. The strip cutting machine innovatively adopts a conveying vehicle 200 for back and forth conveying. The conveying vehicle 200 is specially designed with a two-layer structure corresponding to the vehicle-mounted roller group 211 and the strip plate group 221 respectively; thus:

[0041] 1) When the conveyor 200 moves to the position where the supporting wheel group 212 and the supporting inclined surface group 12 are matched, the vehicle roller group 211 rises to a position higher than the strip plate group 221, and the conveyor 200 is in a roller conveying state, and can smoothly receive the stone delivered in the previous order, or convey the stone on it to the subsequent order;

[0042] 2) When the transport vehicle 200 moves to the point where the supporting wheel group 212 separates from the supporting inclined plane group 12, the corresponding vehicle-mounted roller group 211 drops below the slat group 221, and the stone on the transport vehicle 200 is transferred from the vehicle-mounted roller group 211 to be supported by the slat group 221. At this point, the stone on the transport vehicle 200 is in a ready-to-cut state, and the corresponding saw blade cutting assembly 300 works to cut the stone smoothly and accurately, while the vehicle-mounted roller group 211 sinks to avoid the saw blade cutting, ensuring a reliable, safe and effective cutting operation.

[0043] Furthermore, the purpose of the support inclined plane group 12 is to allow the support wheel group 212 to crawl on it, and the extending direction of the inclined plane of the support inclined plane group 12 is the direction of the wheel of the support wheel group 212 (the direction of the walking rail 11). In order to facilitate the support wheel group 212 to smoothly enter and exit the support inclined plane group 12, the corresponding matching surface of the support inclined plane group 12 and the supporting wheel group 212 is designed to be a first inclined plane, a second inclined plane and a high plane that are sequentially connected from low to high. The high plane is away from the side where the saw blade cutting assembly 300 is located, so that the conveying vehicle 200 can stay there steadily and carry out material conveying operations. The inclination of the first inclined plane is greater than the inclination of the second inclined plane. The crawling process of the support wheel group 212 is appropriately buffered by two inclined planes with different inclinations, thereby improving the stability and reliability of the overall conveying of the conveying vehicle 200.

[0044] In a preferred embodiment, four support wheel groups 212 are provided, each group includes a support rod 2121 and a support wheel 2122 , the support rod 2121 passes through the lower frame 22 and extends downward, and the support wheel 2122 is installed at the bottom of the support rod 2121 .

[0045] The main difference between the first and second solutions of this case lies in the placement and conveying direction of the stone on the conveyor vehicle and the conveying direction of the conveyor vehicle. The purpose of changing the direction relationship between the two is to enable the stone conveyor and slitting machine to be suitable for conveying materials in different directions, as well as for slitting stones in different horizontal and vertical directions. The following is a detailed explanation.

[0046] In the first solution, the conveying direction of the conveying vehicle 200 (i.e., the extension direction of the running rail 11) is arranged in the same direction as the conveying direction of the vehicle-mounted roller group 211. Correspondingly, the frame 100 has a feeding position, a cutting position, and a discharging position arranged in sequence, and the supporting inclined plane group 12 is arranged at the location of the discharging position. This solution is suitable for the first cutting operation of the whole stone. The specific operation steps are as follows:

[0047] Step 1), the conveyor 200 receives the material at the front feeding position, at this time, the supporting wheel group 212 is in a naturally sunken state, the upper frame 21 is directly placed on the lower frame 22 and supported by it, at this time, the vehicle-mounted roller group 211 is lower than the slat group 221, and the stone to be cut is supported by the slat group 221; after the conveyor 200 is transported to the cutting position on the frame 100, the saw blade cutting assembly 300 cuts the stone to be cut on the conveyor 200 into a stone slab group; during the cutting process, the stone is stably placed on the slat group 221 waiting to be cut, and the saw blade group correspondingly saws on the slat group 221, and the sunken vehicle-mounted roller group 211 can avoid the problem that the saw blade group may accidentally cut it. The slat group 221 is preferably made of wooden slats, that is, it is composed of a plurality of wooden slats, which can be disassembled and fixed on the lower frame 22 one by one. Preferably, the lower frame 22 is integrally provided with a bottom plate group 223 composed of a plurality of supporting bottom plates arranged side by side at intervals, so as to facilitate the disassembly, fixation and replacement of the wooden slats one by one.

[0048] Step 2), the conveyor 200 carries the cut stone slab group and continues to convey it forward, and the supporting wheel group 212 touches the supporting inclined surface group 12 and crawls on it. When crawling to the set discharge position (the high plane position of the supporting inclined surface group 12), at this time, the vehicle-mounted roller group 211 rises to be higher than the strip group 221, and the stone slab group on the strip group 221 is taken over; at this time, the conveyor 200 is also transported to the position, waiting to transfer the stone slab group on it.

[0049] In order to transfer the slab group on the conveying vehicle 200, the vehicle roller group 211 is connected to the vehicle transmission assembly 23; there are two driving schemes for the vehicle transmission assembly 23.

[0050] The first one is that the vehicle-mounted transmission component 23 adopts a self-driving mode, that is, the vehicle-mounted transmission component 23 is connected to a driving component, and the vehicle-mounted transmission component 23 is driven by the driving component to finally achieve the purpose of rolling and conveying materials by the vehicle-mounted roller group 211.

[0051] The second type is that the vehicle-mounted transmission component 23 adopts a coupling drive mode, that is, the vehicle-mounted transmission component 23 is connected to a related coupling component, and the coupling component adopts an existing conventional coupling device. The coupling component is divided into two parts, a first coupling part and a second coupling part. The two parts are respectively installed on the vehicle-mounted transmission component 23 and the transmission shaft of the subsequent related material receiving device. The transmission shaft of the related material receiving device is a self-driven form, and the transmission can also adopt a roller group. Therefore, when the conveying vehicle 200 is delivered to the position where the coupling is combined, the vehicle-mounted transmission component 23 of the conveying vehicle 200 and the subsequent related material receiving device are automatically linked and combined with the help of the corresponding coupling component; afterwards, the related material receiving device is self-driven, and while driving its own roller group to roll, it also drives the vehicle-mounted roller group 211 of the conveying vehicle 200 to roll synchronously, and the stone slab group is transported from the vehicle-mounted roller group 211 to the related material receiving device. After that, the conveyor 200 disengages the linkage and returns, repeating the above operation; that is, the continuous and efficient flow operation of stone cutting and conveying is realized. The second method is the preferred method. The conveyor 200 itself does not have the power to automatically convey the stone slab group. The power is provided by the linkage of the relevant material receiving device, that is, it relies on the linkage with the relevant material receiving device. Through the linkage and drive, the front and rear conveying can not only be seamlessly connected, but also there is no need to accurately control the conveying time coordination of the two adjacent conveying sections. The cutting operation control is very simple and reliable.

[0052] The second option, such as Figure 4-6 As shown, the conveying direction of the conveying vehicle 200 (i.e., the extension direction of the running rail 11) is arranged perpendicular to the conveying direction of the vehicle-mounted roller group 211. Correspondingly, the working position design on the frame 100 can be designed in two ways. The first one is similar to the first scheme, with a feeding position, a cutting position and a discharging position arranged in sequence in front and behind, and the support ramp group 12 is arranged at the position of the discharging position. The second one is that the frame has adjacently arranged receiving / discharging positions and cutting positions, that is, the receiving position and the discharging position are arranged in an overlapping manner, and the support ramp group 12 is arranged at the position of the receiving / discharging position; this method is suitable for a second turning and cutting operation on a stone that has been cut once. The specific operating steps are as follows:

[0053] Step 1) The conveyor 200 is at the front end receiving / discharging position of the frame 100, at which time the supporting wheel group 212 is on the high plane of the supporting inclined surface group 12, and the onboard roller group 211 is higher than the slat group 221; the conveyor 200 is in a state of waiting for the previous material to be transferred, and the previous slab group formed by one cutting is transferred to the onboard roller group 211 of the conveyor 200.

[0054] The manner in which the conveyor 200 receives the material transmitted from the preceding sequence, referring to the above situation in which the conveyor 200 delivers the material, also has two modes. The first mode is that the on-board transmission component 23 adopts a self-driving mode; the second mode is that the on-board transmission component 23 adopts a coupling drive mode. When the conveyor 200 is at the front end receiving / discharging position of the frame 100, the conveyor 200 is also at the coupling combination position. With the help of the coupling component, the on-board transmission component 23 and the preceding related feeding device are automatically linked and combined; thereafter, the related feeding device is self-driven, driving its own roller group to roll, and at the same time, driving the on-board roller group 211 of the conveyor 200 to roll synchronously, and the slab group is transported from the related feeding device to the on-board roller group 211.

[0055] Step 2), the on-board roller group 211 of the conveying vehicle 200 carries the stone slab group and moves backward. During the backward movement, the supporting wheel group 212 crawls downward along the supporting inclined surface group 12 accordingly. After descending and separating from the supporting inclined surface group 12, the supporting wheel group 212 is in a natural sinking state, and the upper frame 21 is directly placed on the lower frame 22 and supported by it. At this time, the on-board roller group 211 is lower than the strip board group 221, and the stone slab group to be cut is transferred from the on-board roller group 211 to the strip board group 221 for support; after the conveying vehicle 200 continues to move backward to the cutting position, the saw blade cutting assembly 300 performs secondary turning on the stone slab group and cuts it into a stone strip group of a specific required size to complete the cutting operation.

[0056] Step 3), after the secondary steering cutting is completed, the conveyor vehicle 200 sends out the stone bar group and moves back and forth to repeat the operation. Here, the conveyor vehicle 200 sends out the stone bar group, and the scheme adopted corresponds to the first method of "feeding position-cutting position-discharging position" mentioned above. After the conveyor vehicle 200 completes the secondary steering cutting, it continues to transport backward to the discharging position, and the cut stone bar group is taken out by the relevant material taking device, and then the conveyor vehicle 200 returns to repeat the operation. Corresponding to the second method of "receiving / discharging position-cutting position" mentioned above, considering that the conveyor vehicle 200 needs to return to the front end discharging position to receive the material, the delivery position of the stone bar group in this design can be set correspondingly to the receiving position, and further, the coupling conveying method can be uniformly adopted, so that the time for the conveyor vehicle 200 to operate back and forth once can be shortened, and the efficiency can be improved. Specifically, a coupling discharging machine is provided next to the receiving / discharging position, and a coupling assembly is provided between the coupling discharging machine and the vehicle-mounted transmission assembly 23 of the conveyor vehicle 200. In this way, when the conveyor 200 returns to repeat step 1), the on-board transmission component 23 is linked with the previous related feeding device, and at the same time, the on-board transmission component 23 is also linked with the coupling discharger. The stone slab group that has been cut once by the previous related feeding device is transferred to the on-board roller group 211 of the conveyor 200. At the same time, the cut stone bar group on the on-board roller group 211 can be synchronously sent to the coupling discharger. In this way, the conveyor 200 can perform discharging and receiving operations at the same time, and the production efficiency is further improved.

[0057] In a preferred embodiment, the support wheel set 212 is arranged at the bottom of the upper frame 21 to stagger the wheel line position corresponding to the wheel travel direction of the running wheel set 222. This ensures that the support wheel set 212 and the running wheel set 222 can slide independently without interfering with each other, and is also conducive to the high and low climbing action of the support wheel set 212.

[0058] In a preferred embodiment, the vehicle-mounted roller group 212 is connected to the vehicle-mounted transmission assembly 23, which includes a transmission main shaft 231 and a plurality of helical gear groups; the helical gear groups include corresponding meshing transmission first helical gears 232 and second helical gears 233. The first helical gears 232 of the plurality of helical gear groups are installed on the transmission main shaft 231 at intervals, and the ends of the transmission main shaft 231 are provided for the installation of the coupling assembly 74. The second helical gears 233 of the plurality of helical gear groups are installed on the roller shafts of the roller groups 212 in a one-to-one correspondence. Thus, the transmission main shaft 231 is rotated in conjunction, and the first helical gears 232 and the second helical gears 233 are driven to cooperate, so as to drive the roller group 212 to roll.

[0059] In a preferred embodiment, the frame 100 is provided with a vehicle driving assembly 13 for driving the transport vehicle 200, and the vehicle driving assembly 13 includes a driving motor 131, two transmission wheel groups 132 and a transmission belt; the driving motor 131 is connected to a transmission wheel group 132, the two transmission wheel groups 132 are arranged front and back along the conveying direction, the transmission belt is wound around the two transmission wheel groups 132, and the bottom of the transport vehicle 200 is connected to the transmission belt. In this way, the driving motor 131 drives, drives the transmission belt to drive, and finally drives the transport vehicle 200 to transport. The transmission belt can be a belt, a wire rope, a chain belt, etc.

[0060] In the preferred embodiment, the strip cutting machine is also provided with a limit assembly 800, which includes a limit block 81 and a limit cylinder 82; the limit block 81 is arranged on the upper position of the corresponding vehicle-mounted roller group 211 on the conveying vehicle 200, and the limit cylinder 82 is arranged on the frame 100, and the limit block 81 and the limit cylinder 82 are arranged to cooperate with each other along the front and back. The limit assembly 800 is used to limit and fix the stone during the cutting operation. In particular, in the case of secondary steering cutting, the stone is formed into a stone slab group after one cutting, and the stone slab group is composed of a number of vertical stone slabs stacked horizontally. After the conveying vehicle 200 carries the stone slab group and transports it to the cutting position, before cutting, the limit cylinder 82 first extends forward to cooperate with the limit block 81 to realize the front and rear tightening and limiting of the stone slab group between the two, and then the secondary steering cutting is performed, thereby ensuring the stability of the placement of the stone slab group when the stone slab group is cut as a whole, so as to achieve the purpose of accurate and effective cutting.
