Description

Technical Field

[0001] The utility model relates to the technical field of pipe production and processing, in particular to a material transfer mechanism and a pipe transfer unit capable of realizing separated flow of pipes. Background Art

[0002] As a kind of pipe material, steel pipe is usually produced on an automated assembly line during its production and processing, which includes multiple production processes. The steel pipe needs to flow between the processing stations of different production processes.

[0003] To this end, a material transfer mechanism is usually added between the previous processing station and the next processing station to move the pipe that has completed the previous process a certain distance so that it can be moved to the next processing station or the designated material collection position of the next processing station.

[0004] In some production lines, a pipe rack with an angled upper end surface is used as a material transfer mechanism. The steel pipe first completes the previous processing step in the previous processing station before being fed into the material transfer mechanism. Specifically, the steel pipe that has completed the previous processing step is lowered from the high point of the pipe rack's upper end surface. With the help of gravity, the steel pipe rolls down the upper end of the pipe rack from the high point to the low point into the designated material removal position (unloading position), thereby achieving self-movement of the lateral spacing. When the next processing station is free, the steel pipe located in the designated material removal position will be removed and sent to the next processing station for the next processing step.

[0005] In some assembly line production processes, multiple steel pipes cannot be fed into the same processing station at once, and the previous processing step is faster than the next. Therefore, a steel pipe may not be able to be fed into the next processing station quickly after completing the previous step and must wait until the next processing station is free. Before the next processing station becomes free, the previous processing station may have already processed multiple steel pipes. At this point, if the first pipe in the loading station has not been removed and a second pipe that has completed the previous process is fed into the pipe rack, the second pipe will roll down the pipe rack to the loading station, colliding with and squeezing the pipes already in the loading station. Multiple steel pipes will be squeezed together and temporarily piled up at the designated loading station, hindering loading operations for the next processing step (for example, multiple steel pipes squeezed together can easily squeeze the previous pipe, making it difficult to clamp the previous pipe). Utility Model Content

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0047] The utility model provides a material moving mechanism for moving pipes, in which a baffle assembly is added.

[0048] Example 1:

[0049] like Figure 1-5 As shown in FIG. 1 , a material transfer mechanism for pipe movement is used. In the first embodiment, a structure combining a pipe rack 1 and a set of baffle components is adopted. Figure 2 The diagram shows the structural layout. The baffle assembly includes two baffle assemblies 2, which are connected to the left and right ends of the pipe rack 1, respectively. In use, the two baffle assemblies 2 are arranged side by side in a row. During operation, when a pipe rolls down the upper end surface of the pipe rack 1 and is caught by the baffle assembly, the pipe wall simultaneously contacts the baffles 201 in both baffle assemblies 2.

[0050] The upper end of the pipe rack 1 is higher at the back and lower at the front, with an inclined angle; in this embodiment, the lower part of the pipe rack 1 is the bracket foot 101. A chute plate 3 is provided between the baffle assembly 2 and the pipe rack 1. The structure of the chute plate 3 is shown in FIG. Figure 5 The pipe rack 1 supports the pipes and allows them to roll. Since the upper end is lower in front and higher in the back, and has an inclined angle, the pipes at the upper end of the pipe rack 1 can roll down and move from the back to the front along the upper end of the pipe rack 1 without any obstruction.

[0051] like Figure 3 As shown, the baffle assembly 2 includes a baffle 201 extending up and down for preventing the pipe from rolling downward along the upper end of the pipe rack, a baffle driving component for driving the baffle 201 to move up and down, and a mounting base 204; in this embodiment 1, the baffle driving component is a cylinder 202, and the power of the cylinder 202 is provided by the air compressor station, which can realize automatic operation and manual linkage.

[0052] The cylinder 202 is connected to the mounting base 204; the chute plate 3 is fixedly connected to the pipe rack 1; the chute plate 3 is provided with a chute 304 extending forward and backward. In this embodiment, the chute 304 is a long strip, and the left and right ends of the chute 304 are connected (such as Figure 5 As shown). In the first embodiment, a fastening bolt 301 and a fastening nut 302 are also included. The fastening bolt 301 passes through the installation base plate 204 and the chute plate 3 in sequence and is fastened to the fastening nut 302 (as shown). Figure 4As shown). In this way, the mounting base plate 204 is connected to the pipe rack 1 through the fastening components (fastening bolts 301 and fastening nuts 302) and the chute plate 3.

[0053] Since the baffle assembly 2 and the chute plate 3 are fastened together by fastening components, when we need to adjust the relative position between the baffle assembly 2 and the chute plate 3 (i.e., the chute plate 3 does not move, and the installation point of the baffle assembly 2 is adjusted), we can loosen the nut 302, adjust the baffle assembly 2 as a whole to the preset position, and then re-tighten the fastening bolt 301 and the fastening nut 302 to fix the installation point of the baffle assembly 2. At the same time, the chute 304 extends forward and backward (such as Figure 1 、 5 During operation, the baffle assembly 2 can be moved back and forth along the chute 304 before being tightened, making adjustment of the fastening position of the baffle assembly 2 more flexible and precise. Furthermore, the use of fastening components to connect the baffle assembly 2 to the chute plate 3 provides a detachable connection, making the baffle assembly 2 more flexible to assemble and disassemble. Furthermore, if a single baffle assembly becomes damaged and needs to be replaced, it can be removed and replaced individually, reducing repair and replacement costs.

[0054] In this embodiment 1, Figure 2 As shown, in the use state, we adjust the two baffle assemblies 2 at the left and right ends of the pipe rack 1 to a symmetrical state, that is, symmetrically distributed at the left and right ends of the pipe rack 1. The two baffle assemblies 2 symmetrically distributed at the left and right ends of the pipe rack 1 are arranged in a row to form a baffle assembly combination, which is located between the upper material position 501 and the lower material position 502. Figure 2 As shown, the two baffles 201 in the same baffle assembly are arranged side by side.

[0055] The layout diagram of the pipe rack 1, baffle assembly 2 and chute plate 3 is as follows Figure 2 As shown. Since the installation position of the baffle assembly 2 is adjustable, we can adjust the positions of the baffle assemblies 2 at the left and right ends synchronously and then tighten them according to needs.

[0056] The material transfer mechanism in the first embodiment is suitable for the situation where the processing rhythm between the previous processing station and the next processing station is not much different.

[0057] Of course, we can also install multiple baffle assemblies 2 connected to the pipe rack 1 via chute plates 3 at the left and right ends of the pipe rack 1 as needed. Then, during use, multiple rows of baffle assemblies are formed (each baffle assembly includes two baffle assemblies 2 arranged side by side on the left and right sides), and the front and rear rows are spaced apart from each other. This allows multiple rows of baffle assemblies to be formed in the material transfer mechanism, which is used to simultaneously separate and hold two or more pipes at the top of the pipe rack, to accommodate situations where the processing rhythm between the previous processing station and the next processing station is significantly different.

[0058] like Figure 2 As shown, the material moving mechanism in the first embodiment can be applied to the material moving operation of pipes between two workstations. We can reasonably design the left and right widths of the upper end of the pipe rack 1 according to the length of the pipe itself.

[0059] During operation, we can choose to load several individual pipes sequentially into the top of pipe rack 1. Specifically, the first pipe is placed into the top of pipe rack 1 from the rear. At this point, the first pipe is located at the highest point of the top of pipe rack 1 and will roll forward along the back of the top of pipe rack 1 until it is stopped by the inclined blocking surfaces 208 of the two baffles 201. At this point, we can activate the two cylinders 202, driving the two baffles 201 downward to their lowest point, thereby removing the obstruction in front of the first pipe (the pipe is released). The pipe continues to roll downward. After the first pipe is released, the two baffles 201 immediately return to their original position and move upward, freeing the high point behind them. The released first pipe continues to roll downward until it abuts against the stop block 102 and stops. At this point, the top of pipe rack 1 behind the stop block 102 is the unloading position. When the next processing station is free, the gripper grabs the pipe in the unloading position. Before the pipe in the unloading position is taken away, we can continue to put the second pipe into the loading position. When the second pipe is blocked by the baffle and stops moving, the second pipe can temporarily stay at the upper end of the pipe rack 1 and wait until the first pipe is taken away before being released downward.

[0060] When the number of baffle assemblies 2 between the upper material position 501 and the lower material position 502 increases and a plurality of baffle assembly combinations can be formed, we can separate and retain multiple pipes at the upper end of the pipe rack 1 in the same manner as described above, and make the front and rear adjacent pipes separated by baffles. Moreover, when a pipe is located at the lower material position 502, since there is no squeezing and pushing of other pipes behind the pipe, the resistance encountered when removing it from the lower material position 502 will be smaller.

[0061] Through the above operation, we have achieved the lateral displacement of a single pipe (moving from the upper material position to the lower material position), and at the same time, achieved the separation between the front and rear pipes on the pipe rack 1, and each pipe is separated and can be released to flow individually.

[0062] In the first embodiment, the stop block 102 is a component fixedly connected to the front end of the pipe rack 1. It protrudes from the upper end of the pipe rack 1 and is used to block the pipe material that has rolled down to the unloading position, causing it to remain at the unloading position. The unloading position is where the material removal equipment grabs the pipe material and transfers it to the next processing station. The stop block 102 can be set at the upper end of the pipe rack 1 or at the front side of the pipe rack 1 (i.e., the position where the pipe material rolls forward from the front side of the upper end of the pipe rack and then stops). When the unloading position is at the front side of the pipe rack 1, the stop block 102 can be synchronously moved forward to the front side of the front end of the pipe rack 1. Accordingly, in the first embodiment, the stop block 102 is no longer fixedly connected to the front end of the pipe rack 1.

[0063] Preferably, in the first embodiment, the upper rear end surface of the baffle 201 is set as an inclined surface, namely, an inclined blocking surface 208. When the pipe is in contact with the baffle 201, the curved wall of the pipe is in contact with the inclined blocking surface 208.

[0064] In the first embodiment, the baffle assembly 2 also includes a pressure plate 205 connected to the mounting base plate 204, and the pressure plate 205 is fixedly connected to the mounting base plate 204 by fastening screws 206; a limiting groove with an upper end opening is also provided between the pressure plate 205 and the mounting base plate 204; the lower end of the baffle 201 is inserted into the limiting groove, and the baffle 201 is slidingly connected to the limiting groove. In the first embodiment, the limiting groove is through-through, and the limiting groove plays a certain limiting role in the up and down movement of the baffle 201, and can be used to limit excessive lateral displacement of the baffle 201 during the up and down movement.

[0065] at the same time, Figure 3 is a structural diagram of the baffle assembly 2, as shown in Figure 3 As shown, in this embodiment 1, in the baffle assembly 2, the piston rod of the cylinder 202 is connected to the baffle 201 via a pin 207. The pin 207 extends horizontally to the left and right, with one end of the pin 207 connected to the side wall of the baffle 201 and the other end of the pin 207 fixedly connected to the piston rod of the cylinder 202. The cylinder 202 is fixedly connected to the mounting base 204 via a cylinder support 203 and screws.

[0066] In addition, a movable limiting groove is provided on the side wall of the pressure plate 205 for the pin shaft 207 to pass up and down; the movable limiting groove extends longitudinally and is located between the cylinder 202 and the mounting base plate 204.

[0067] In a steel pipe production line, some steel pipes are relatively long. Therefore, based on Example 1, a material transfer mechanism can be constructed by arranging multiple pipe racks 1 in parallel. In this arrangement and combination, the material transfer mechanism includes multiple pipe racks 1 arranged side by side. Each pipe rack 1 is provided with a baffle assembly 2 at each end, with a chute plate 3 connected between the baffle assembly 2 and the pipe rack 1. Each baffle assembly 2 is connected to the chute plate 3 via a fastening bolt 301 and a fastening nut 302. Specifically, as in Example 2 and Example 3, the number of pipe racks 1 and the number of baffle assemblies 2 can be adjusted according to specific circumstances.

[0068] Example 2:

[0069] like Figure 6 As shown, in the second embodiment, we can combine two pipe racks 1 with baffle assemblies 2, and use the method of arranging the two pipe racks 1 side by side to form a material moving mechanism.

[0070] Figure 6 The schematic diagram of the structural layout of the material moving mechanism is shown in a top view, which includes two pipe racks 1. A baffle assembly 2 is provided at the left and right ends of each pipe rack 1. Each baffle assembly 2 includes a baffle 201. At the same time, since the installation position between the baffle assembly 2 and the chute plate 3 can be fastened and locked by a fastening component after the movement is determined, we adjust the positions of the four baffle assemblies 2 to the following: Figure 6 Tighten and lock after the state shown.

[0071] In the second embodiment, the total number of baffle assemblies 2 in the material transfer mechanism is four. The two baffle assemblies 2 at the lower point (i.e., the two baffle assemblies 2 on the front side) are arranged side by side in a row, forming a baffle assembly combination; the two baffle assemblies 2 at the higher point (i.e., the two baffle assemblies 2 on the rear side) are arranged in a row, forming a baffle assembly combination; the two baffle assembly combinations are spaced apart in front and back. Figure 6 shown.

[0072] The distance between the front and rear baffle assemblies can be adjusted and then locked to accommodate steel pipes of different diameters. Figure 6 As shown, in this second embodiment, three steel pipes (respectively, a low-position steel pipe 401, a middle-position steel pipe 402, and a high-position steel pipe 403) are simultaneously held at the top of two pipe racks 1, with adjacent steel pipes separated by baffles 201. Multiple steel pipes that have completed the previous processing step can be temporarily held at the top of the pipe racks 1 until the next processing station becomes available, with the steel pipes at the top of the pipe racks 1 separated by baffles.

[0073] The steel pipe located in the unloading position 502 is the steel pipe located at the front (i.e. the steel pipe close to the rear end of the stop block 102), which is the low-position steel pipe 401; the steel pipe located in the loading position 501 is the steel pipe located at the rear end, which is the high-position steel pipe 403; the steel pipe located in the middle is the middle-position steel pipe 402. Figure 7 、 8 As shown, because the distance between the stop block 102 and the baffle 201 behind it is much larger than the diameter of the low-position steel tube 401, there is a certain distance between the low-position steel tube 401 and the rear baffle, and the low-position steel tube 401 and the middle-position steel tube 402 are not in direct contact. However, the walls of the middle-position steel tube 402 and the walls of the high-position steel tube 403 are mainly pressed against the baffle, so that the high-position steel tube 403 and the middle-position steel tube 402 are close to each other without excessively squeezing each other. Of course, the front-to-back distance between the two sets of baffle assemblies can be further increased to prevent the high-position steel tube 403 and the middle-position steel tube 402 from directly contacting each other.

[0074] On the pipe rack 1, the low-position steel pipe 401, the middle-position steel pipe 402, and the high-position steel pipe 403 are arranged in sequence from front to back. During operation, when the low-position steel pipe 401 is removed from the unloading position 502 by the material-removing equipment, the unloading position 502 will be vacated. At this time, the two baffles 2 in the lower position move down to the lowest point, and the obstruction on the front side of the middle-position steel pipe 402 disappears. The middle-position steel pipe 402 is released and rolls into the vacated unloading position 502. At the same time, the two baffles 2 in the lower position reset and move up to form a longitudinal obstruction. Then, the two baffles 2 in the higher position move down to the lowest point, and the obstruction on the front side of the high-position steel pipe 403 disappears. The high-position steel pipe 403 is released and rolls into the original position of the middle-position steel pipe 402. At the same time, the two baffles 2 in the higher position reset and move up to form a longitudinal obstruction, and a new steel pipe is placed in the loading position 501. This cycle can achieve continuous material transfer. Through the above operation, the steel pipe transfer between the two workstations is realized, and with the help of multiple baffles 201 that can move up and down, a single steel pipe can be rolled separately on the upper end of the pipe rack 1, while the other steel pipes are temporarily separated and stay on the pipe rack; each steel pipe can be released separately into the unloading position 502 to wait for the next processing station to be idle; when there is already a steel pipe in the unloading position 502, the remaining steel pipes can be separated and temporarily stored at the upper end of the pipe rack, which can avoid the problem of multiple steel pipes being close to each other and squeezed in the unloading position 502.

[0075] At the same time, compared with the first embodiment, the second embodiment adopts a combined layout scheme of two pipe racks arranged side by side. There is a distance between the two pipe racks. We can flexibly adjust the distance between the two pipe racks according to the length of the steel pipe and are not limited to the width of a single pipe rack 1.

[0076] Of course, we can also increase the number of baffle assemblies 2 on the pipe rack 1 as needed to form multiple groups of baffle assembly combinations that are spaced apart from each other in the front and back, and each group of baffle assembly combinations includes at least two baffle assemblies 2 located on the same straight line (that is, arranged in a row on the left and right).

[0077] The side view of the second embodiment can be seen in Figure 7 As shown, the side view of embodiment 2 (including steel pipe) is shown in FIG. Figure 8 shown.

[0078] Example 3:

[0079] On the basis of the second embodiment, we increase the number of pipe racks 1 and baffle assemblies 2, and then provide another example of a combination solution. Figure 9 FIG. 1 is a schematic diagram showing the layout of various components in another combination scheme from a top view. In this third embodiment, we have selected a layout scheme of three pipe racks 1 arranged side by side.

[0080] In the solution of the third embodiment, the material transfer mechanism includes three pipe racks 1 arranged side by side, and the number of baffle assemblies 2 connected to the left and right sides of each pipe rack 1 is different. Figure 9 As shown, each pipe rack 1 is equipped with a total of three baffle assemblies 2; the entire material transfer mechanism includes nine baffle assemblies 2. Similarly, these nine baffle assemblies 2 together form two baffle assembly combinations, spaced apart from each other. The five baffle assemblies 2 at the lower point (i.e., the five baffle assemblies 2 near the front) are arranged side by side in a row to form one baffle assembly combination; the four baffle assemblies 2 at the higher point (i.e., the four baffle assemblies 2 near the rear) are arranged side by side in a row to form another baffle assembly combination.

[0081] The structures of the baffle assembly 2, the chute plate 3 and the pipe rack 1 in the first, second and third embodiments are the same, and the connection methods among the baffle assembly 2, the chute plate 3 and the pipe rack 1 are the same. Figure 3-5 .

[0082] In addition, Figure 1-5 Based on the first embodiment shown, a new component unit, namely, a pipe material transfer unit, can be formed by removing the baffle assembly 2 connected to the left or right end of the pipe rack 1 and the corresponding chute plate 3. In other words, the pipe material transfer unit comprises only one pipe rack 1, with at least one baffle assembly 2 provided only at the left or right end of the pipe rack 1. The baffle assembly 2 is also fastened to the chute plate 3 via fastening bolts 301 and fastening nuts 302, while the chute plate 3 is fixedly connected to the pipe rack 1.

[0083] The pipe transfer unit is also composed of an angled pipe rack 1 combined with a baffle assembly 2. However, the baffle assembly 2 is only connected to one side of the pipe rack 1. Multiple such side-by-side pipe transfer units can form a pipe transfer mechanism for transferring pipes between two workstations.

[0084] Specifically, if Figure 10 As shown in the figure, it is a structural layout diagram of an example of a pipe material moving mechanism formed by combining two pipe material moving units. The upper end of each pipe rack 1 is higher at the back and lower at the front, and the front end of each pipe 1 is connected to a limit block 102. The rear side of the limit block 102 is also the unloading position, and the position of the high-position steel pipe 403 is still the loading position. In one pipe material moving unit, two baffle assemblies 2 are connected to the left end of the pipe rack; in the other pipe material moving unit, two baffle assemblies 2 are connected to the right end of the pipe rack, for a total of four baffle assemblies 2. The two baffle assemblies 2 at the lower point on the front side are arranged side by side in a row, forming a group of baffle assembly combinations; the two baffle assemblies 2 at the higher point on the rear side are also arranged side by side in a row, forming another group of baffle assembly combinations.
