Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to a material transmission device, an automatic feeding device and an automatic feeding method. Background Art

[0002] Belt conveyors are widely recognized for their low cost, low maintenance cost and large conveying capacity. In actual production, belt conveyors often transport large materials, which makes operation very difficult both in terms of maintenance and in transporting materials.

[0003] Chinese patent CN218173648U discloses a belt conveyor roller for coal mines, which includes a main shaft and a roller. The roller is arranged on the outer surface of the main shaft and a disassembly mechanism is arranged inside the roller, so as to facilitate the maintenance of the belt conveyor.

[0004] Obviously, although the problem of belt conveyor maintenance has been solved, when conveying large materials, such as extra-long pipes, for example, in the belt conveyor roller processing workshop, the loading and unloading of pipes are batch and cumbersome. The workers' routine operation is usually to pick up the materials. Because the pipes are too long, generally 6-9 meters, they need to first lift the whole bundle of long pipes to the ground with a crane, then spread them out, and then send them one by one to the pipe cutting machine for cutting. You can imagine how difficult and intense the operation is.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art known to a person skilled in the art. Summary of the invention

[0006] The technical problem to be solved by the present invention is: how to convey materials quickly and accurately.

[0007] The present invention solves the above technical problems through the following technical means:

[0008] A material transmission device comprises a material loading rack, a transmission assembly, a rolling bracket and a feeding assembly, wherein a material blocking member is arranged on the material loading rack, wherein the material blocking member is used to limit the pipe to be transmitted to a first station;

[0009] Transmission components are arranged on both sides of the material blocking member, the transmission components are located below the pipe to be transmitted at the first station, and the transmission components and the loading rack are staggered with each other, wherein the transmission components are used to drive the pipe to be transmitted to move from one side of the material blocking member to the other side of the material blocking member, and transfer the pipe to be transmitted to the second station;

[0010] The second station is provided with a rolling support, wherein the rolling support is used to support the pipe to be transported;

[0011] The feeding assembly pushes the pipe to be transported to the third station, and the pushing direction of the feeding assembly is the same as the rolling direction of the rolling bracket.

[0012] Preferably, the transmission component includes a lifting unit and a lifting block, the lifting units are installed on both sides of the loading rack, and the lifting units are located below the pipe to be transported at the first workstation, and the lifting block is installed at the output end of the lifting unit, wherein the lifting unit is used to drive the lifting block to move along the height direction, and the upper end surface of the lifting block has an inclined surface inclined downward toward the blocking member.

[0013] Preferably, the side surface of the top block is a V-shaped structure that is symmetrical along the center, and the center of the top block deviates from the material blocking piece.

[0014] Preferably, the feeding assembly comprises a first driving unit, a second driving unit and a first roller, the first driving unit is arranged on a side of the loading rack away from the material blocking member, and the second driving unit is arranged on an output end of the first driving unit, wherein the first driving unit is used to drive the second driving unit to move along the height direction;

[0015] A first roller is installed at the output end of the second driving unit. The first roller is located above the pipe to be transported, the surface of the first roller is in contact with the pipe to be transported, and the axis of the pipe to be transported and the axis of the first roller are perpendicular to each other, wherein the second driving unit is used to drive the first roller to rotate around the axis.

[0016] Preferably, the rolling bracket includes a bracket body and a second roller. The bracket body is arranged on the side of the loading rack away from the material blocking member. The second roller is connected to the bracket body and is located below the pipe to be conveyed. The second roller is in contact with the pipe to be conveyed, and the axis of the pipe to be conveyed and the axis of the first roller are perpendicular to each other.

[0017] Preferably, the loading rack is a horizontal bracket, and a vertical plate is installed at the edge of the loading rack close to the second station, and the vertical plate is the material blocking member.

[0018] Preferably, the first workstation and / or the second workstation and / or the third workstation is provided with a monitoring component, wherein the monitoring component is used to monitor whether the pipe to be transported is transported to the corresponding workstation.

[0019] The present invention also claims protection for an automatic feeding device, using a material transmission device, including a material storage rack and a quantity control component, wherein the material storage rack is installed on the side of the loading rack away from the material blocking member, wherein the material storage rack is used to store the pipes to be transmitted, and a material discharge port is provided on the side of the material storage rack facing the loading rack, and the material discharge port is located above the loading rack;

[0020] The bearing surface of the material storage rack is an inclined surface inclined downward toward the material discharge port, and a quantity control component is arranged at the material discharge port, wherein the quantity control component is used to limit the number of pipes to be transported flowing out of the material storage rack.

[0021] Preferably, the quantity control component includes a third drive unit and a stop pin. The third drive unit is installed on the storage rack below or above the discharge port. The stop pin is installed at the output end of the third drive unit to form a fixed end, and the stop pin suspension end faces the discharge port, wherein the third drive unit is used to drive the stop pin to move along the height direction.

[0022] The present invention also claims protection for an automatic feeding method, using an automatic feeding device, comprising:

[0023] The third driving unit is driven, the stop pin is away from the discharge port, and the pipe to be conveyed flows to the loading rack, and the blocking member restricts the pipe from being conveyed to the first station;

[0024] Receiving the monitoring signal from the first station monitoring component, driving the transmission component, and moving the pipe to be transmitted from one side of the material blocking member to the other side of the material blocking member, and transferred to the rolling bracket located at the second station;

[0025] Receiving the monitoring signal from the second station monitoring component, driving the feeding component to push the pipe to be transported to the third station;

[0026] After receiving the monitoring signal from the third station monitoring component, automatic feeding is completed.

[0027] The advantages of the present invention are:

[0028] 1. The present invention requires protection of the material transmission device. By setting a material blocking piece on the loading rack, several pipes can be restricted to the first station in turn, which is convenient for the precise positioning and transmission of the transmission component. The transmission component transfers the pipe to be transmitted to the rolling bracket. This step has at least four benefits: Benefit 1. Avoid the feeding component from pushing other pipes by mistake during operation; Benefit 2. Separate the feeding component and the loading rack to avoid mutual interference and damage during operation; Benefit 3. There is rolling friction between the rolling bracket and the pipe to be transmitted. Compared with directly pushing on the loading rack, it is obvious that the friction force is reduced, which reduces the damage to the pipe to be transmitted. Secondly, it also makes the power used to push the feeding component smaller, saving energy. Benefit 4. Staggering the third station with the first station means that the loading rack and the device of the next process are staggered to make room for the device of the next process.

[0029] 2. The effects achieved by the transmission component are mainly, first, to lift the pipe to be transported, and secondly, to push the pipe to be transported from one side of the material blocking member to the other side. In fact, this effect can also be achieved by two linear drive devices that are perpendicular to each other. However, the present invention arranges a top block on a lifting unit, and the special shape of the top block cooperates with the blocking effect of the material blocking member to fully achieve this effect. It can be imagined that not only the energy loss is reduced, but also the interference and time interval error between the two linear drive devices are avoided. It can be said that it kills two birds with one stone. As for how the top block and the material blocking piece cooperate, the present invention sets the upper end surface of the top block as an inclined surface inclined downward toward the blocking piece. First, in the initial state, the pipe to be conveyed is located at the first station. Then, when the lifting unit drives the top block to push up, the top block is not higher than the material blocking piece at this time, so the pipe to be conveyed is located between the top block and the material blocking piece and is in a clamped state. Then, the lifting unit continues to push up. At this time, the top block is higher than the material blocking piece, and the pipe to be conveyed is higher than the material blocking piece. Under the action of the inclined surface of the top block and without the obstruction of the material blocking piece, the pipe to be conveyed slides to the other side of the material blocking piece. Finally, the lifting unit moves downward. When it moves to below the second station, the pipe to be conveyed is placed on the rolling bracket.

[0030] 3. Furthermore, the side surface of the top block is a V-shaped structure that is symmetrical along the center. In fact, not only the V-shape, but also semicircular and concave shapes can achieve this effect, and therefore they all belong to the protection scope of the present invention. The reason for designing this shape is mainly to prevent the conveying pipe from continuously sliding or rolling after it is separated from the obstruction of the material blocking piece, causing it to separate from the surface of the top block.

[0031] Fourth, the main effect of the feeding assembly is to move the pipe to be transported to the third station. By setting the first drive unit, the second drive unit is driven away from or close to the pipe to be transported. This setting is mainly to stagger the position of the jacking unit to avoid damage and emergency stop of transmission caused by collision or interference. The pipe to be transported is pushed to the third station by the action of the first roller and the second drive unit. In fact, directly setting a linear push device at the end of the pipe to be transported seems to be able to meet the pushing effect. However, in fact, there are three advantages of setting the first roller and the second drive unit compared to setting a linear push device: Advantage 1. The rotation of the first roller is relatively direct push, which is gentler, has less friction, and causes less damage to the pipe to be transported; Advantage 2. During transmission, due to the reduction of friction, the movement is naturally smoother during transmission; Advantage 3. For heavy objects, rolling friction can significantly reduce the difficulty of pushing, so it just fits well with the original intention of the present invention to mainly solve the transmission of heavy pipes; Advantage 4. The first roller can provide stability of the work number and reduce the risk of tilting or overturning of the pipe to be transported.

[0032] 5. By setting up monitoring components at the first station and / or the second station and / or the third station, it is possible to monitor whether the pipes to be transported are transported to the corresponding stations. Firstly, it can improve the accuracy of transmission. Secondly, it can improve the effect of automation, reduce human resources, and be more in line with the general trend of production.

[0033] 6. The present invention also claims protection for an automatic feeding device. If a material transmission device is only used to solve the transfer of pipes to be transmitted, then an automatic feeding device can solve the problem from the source that workers need to spread all the pipes on the ground and then rearrange them when loading materials. In addition to material transmission, it also increases the benefits of warehousing. When combined with the quantity control component, it can realize the automation between warehousing and material transmission, which can be said to be icing on the cake.

[0034] 7. The quantity control component controls the outflow of the pipe fittings to prevent the pipe fittings from piling up on the loading rack. The third driving unit drives the stop pin to move in the height direction, so that the pipe fittings outside the stop pin length flow out along the discharge port.

[0035] 8. The present invention also claims protection for an automatic feeding method, which realizes the effect of automatic feeding by cooperating with the transmission component, the feeding component and the monitoring component of the corresponding workstation.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0051] Embodiment 1

[0052] See also Figure 1 , the disclosure of the present invention claims a material transmission device, including a loading rack 10, a transmission assembly 11, a rolling bracket 12 and a feeding assembly 13, a material blocking member 100 is provided on the loading rack 10, wherein the material blocking member 100 is used to limit the pipe to be transmitted to the first station;

[0053] In this embodiment, transmission components 11 are arranged on both sides of the material blocking member 100, and the transmission components 11 are located below the pipe to be transmitted at the first station, and the transmission components 11 and the loading rack 10 are staggered with each other, wherein the transmission components 11 are used to drive the pipe to be transmitted to move from one side of the material blocking member 100 to the other side of the material blocking member 100, and transfer the pipe to be transmitted to the second station;

[0054] It is worth noting that the loading rack 10 is a horizontal bracket, and a vertical plate is installed at the edge of the loading rack 10 close to the second station, and the vertical plate is a material blocking member 100.

[0055] For further information, see Figure 2 - Figure 4The transmission component 11 includes a lifting unit 110 and a top block 111. The lifting units 110 are installed on both sides of the loading rack 10, and the lifting units 110 are located below the pipe to be transmitted at the first workstation. The top block 111 is installed at the output end of the lifting unit 110, wherein the lifting unit 110 is used to drive the top block 111 to move along the height direction, and the upper end surface of the top block 111 has an inclined surface inclined downward toward the blocking member.

[0056] It is worth noting that the lifting unit 110 is the first cylinder, which is installed under the loading rack 10 through a fixed plate. The output shaft of the first cylinder passes through the fixed plate and is connected to the top block 111. A linear bearing is arranged between the fixed plate and the output shaft of the first cylinder for guiding and reducing friction. The thickness of the first cylinder is generally 150mm.

[0057] The effects achieved by the transmission component 11 are mainly, first, to lift the pipe to be transported, and second, to push the pipe to be transported from one side of the blocking member 100 to the other side. In fact, this effect can also be achieved by two linear drive devices that are perpendicular to each other. However, the present invention provides a top block 111 on a lifting unit 110. The special shape of the top block 111 cooperates with the blocking effect of the blocking member 100 to fully achieve this effect. It can be imagined that not only the energy loss is reduced, but also the interference and time interval error between the two linear drive devices are avoided. It can be said that two birds with one stone are killed. As for how the top block 111 cooperates with the material blocking member 100, the present invention sets the upper end surface of the top block 111 as an inclined surface inclined downward toward the blocking member. First, in the initial state, the pipe to be conveyed is located at the first station. Then, when the lifting unit 110 drives the top block 111 to push up, at this time, the top block 111 is not higher than the material blocking member 100, so the pipe to be conveyed is located between the top block 111 and the material blocking member 100 and is in a clamped state. Then, the lifting unit 110 continues to push up. At this time, the top block 111 is higher than the material blocking member 100, and makes the pipe to be conveyed higher than the material blocking member 100. Under the action of the inclined surface of the top block 111 and without the obstruction of the material blocking member 100, the pipe to be conveyed slides to the other side of the material blocking member 100. Finally, the lifting unit 110 moves downward. When it moves to below the second station, the pipe to be conveyed is placed on the rolling bracket 12.

[0058] Furthermore, the side surface of the top block 111 is a V-shaped structure that is symmetrical along the center, and the center of the top block 111 deviates from the material blocking member 100 .

[0059] Furthermore, the side surface of the top block 111 is a V-shaped structure that is symmetrical along the center. In fact, not only the V-shape, but also a semicircular shape and a concave shape can achieve this effect, and therefore they all belong to the protection scope of the present invention. The reason for designing this shape is mainly to prevent the conveying pipe from continuously sliding or rolling after it is separated from the obstruction of the material blocking member 100, thereby causing it to separate from the surface of the top block 111.

[0060] See also Figure 2-Figure 4 The second station is provided with a rolling support 12, wherein the rolling support 12 is used to support the pipe to be transported;

[0061] Furthermore, the rolling bracket 12 includes a bracket body 120 and a second roller 121. The bracket body 120 is arranged on the side of the loading rack 10 away from the material blocking member 100. The second roller 121 is connected to the bracket body 120, and the second roller 121 is located below the pipe to be conveyed. The second roller 121 is in contact with the pipe to be conveyed, and the axis of the pipe to be conveyed and the axis of the first roller 132 are perpendicular to each other.

[0062] It is worth noting that a height-adjusting screw bracket may be provided between the rolling bracket 12 and the bracket body 120 to adjust the height of the rolling bracket 12 so that the second roller 121 is more closely fitted to the pipe to be transported.

[0063] For further information, see Figure 2 - Figure 4 The feeding assembly 13 pushes the pipe to be transported to the third station, and the pushing direction of the feeding assembly 13 is the same as the rolling direction of the rolling bracket 12.

[0064] Furthermore, the feeding assembly 13 includes a first driving unit 130, a second driving unit 131 and a first roller 132, the first driving unit 130 is arranged on the side of the loading rack 10 away from the material blocking member 100, and the second driving unit 131 is arranged on the output end of the first driving unit 130, wherein the first driving unit 130 is used to drive the second driving unit 131 to move along the height direction;

[0065] A first roller 132 is installed at the output end of the second driving unit 131. The first roller 132 is located above the pipe to be transported. The surface of the first roller 132 contacts the pipe to be transported, and the axis of the pipe to be transported and the axis of the first roller 132 are perpendicular to each other. The second driving unit 131 is used to drive the first roller 132 to rotate around the axis.

[0066] It is worth mentioning that the first drive unit 130 is a first cylinder, the second drive unit 131 is a three-phase asynchronous motor and a worm gear reducer used therewith, the first drive unit 130 is installed on the loading rack 10 through a first hinge seat, and the second drive unit 131 is installed on the output end of the first drive unit 130 through a second hinge seat. In this way, the angle of the feeding component 13 can be adjusted, which is not only more practical, but also can avoid other devices and reduce collisions and interference. Moreover, according to pipes of different diameters, the angle of the feeding component 13 can be adjusted to make the first roller 132 fit the pipe to be transported.

[0067] The feeding assembly 13 mainly realizes the effect of moving the pipe to be transported to the third station. By setting the first driving unit 130, the second driving unit 131 is driven to move away from or close to the pipe to be transported. This setting is mainly to stagger the position of the lifting unit 110 to avoid damage or sudden stop of transmission caused by collision or interference. The pipe to be transported is pushed to the third station by the first roller 132 and the second driving unit 131. In fact, it seems that a linear pushing device can be directly set at the end of the pipe to be transported to meet the pushing effect. However, in fact, by setting the first roller 132 and the second driving unit 131, the pipe to be transported is pushed to the third station. Compared with setting up a linear pushing device, the two driving units 131 have three advantages: Advantage 1, the rotation of the first roller 132 is relatively direct, which is gentler, has less friction, and causes less damage to the pipe to be transported; Advantage 2, during transmission, since the friction is reduced, the movement is naturally smoother; Advantage 3, for heavy objects, rolling friction can significantly reduce the difficulty of pushing, so it just fits well with the original intention of this embodiment to mainly solve the transmission of heavy pipes; Advantage 4, the first roller 132 can provide stability for the work number and reduce the risk of tilting or overturning of the pipe to be transported.

[0068] It is worth noting that the first station and / or the second station and / or the third station are provided with a monitoring component, wherein the monitoring component is used to monitor whether the pipe to be transported is transported to the corresponding station.

[0069] The monitoring component is generally a proximity switch or sensor. The first station monitoring component is installed on the side of the material blocking member 100 close to the pipe to be transported, the second station monitoring component is on the rolling bracket 12, and the third station monitoring component is located at the device entrance of the next process.

[0070] By setting up monitoring components at the first station and / or the second station and / or the third station, it is possible to effectively monitor whether the pipe to be transported is transported to the corresponding station. Firstly, it can improve the accuracy of transmission, and secondly, it can improve the effect of automation, reduce human resources, and be more in line with the general trend of production.

[0071] This embodiment requires protection of a material transmission device. By setting a material blocking member 100 on the loading rack 10, several pipes can be restricted to the first station in turn, which is convenient for the accurate positioning and transmission of the transmission component 11. The transmission component 11 transfers the pipe to be transmitted to the rolling bracket 12. This step has at least four benefits: Benefit 1: Avoid the feeding component 13 from pushing other pipes by mistake during operation; Benefit 2: Separate the feeding component 13 and the loading rack 10 to avoid mutual interference and damage during operation; Benefit 3: There is rolling friction between the rolling bracket 12 and the pipe to be transmitted. Compared with directly pushing on the loading rack 10, it is obvious that the friction force is reduced, which reduces the damage to the pipe to be transmitted. Secondly, it also makes the power used to push the feeding component 13 smaller, saving energy. Benefit 4: Staggering the third station with the first station means that the loading rack 10 is staggered with the device of the next process, making room for the device of the next process.

[0072] Embodiment 2

[0073] refer to Figure 5 and Figure 6 This embodiment adopts a material transmission device in the first embodiment. This embodiment claims to protect an automatic feeding device, including a storage rack 2 and a quantity control component 3. The storage rack 2 is installed on the side of the loading rack 10 away from the material blocking member 100, wherein the storage rack 2 is used to store the pipes to be transmitted, and a discharge port is provided on the side of the storage rack 2 facing the loading rack 10, and the discharge port is located above the loading rack 10;

[0074] The bearing surface of the storage rack 2 is an inclined surface inclined downward toward the discharge port, and a quantity control component 3 is arranged at the discharge port, wherein the quantity control component 3 is used to limit the number of pipes to be transported flowing out of the storage rack 2.

[0075] It is worth mentioning that both the loading rack 10 and the storage rack 2 are welded from square tube profiles, which can ensure the overall stability. The bearing surface of the storage rack 2 forms an inclination angle of 2° with the horizontal plane to form an inclined surface. During actual operation, the pipes are automatically dropped from the discharge port due to the gravity of the pipes.

[0076] This embodiment also requires protection of an automatic feeding device. If a material transmission device is only used to solve the transfer of pipes to be transmitted, then an automatic feeding device can solve the problem of workers spreading all the pipes on the ground and rearranging them when loading materials. In addition to material transmission, it also increases the benefits of warehousing. When combined with the quantity control component 3, automation between warehousing and material transmission can be achieved, which can be said to be icing on the cake.

[0077] refer to Figure 5 and Figure 6The quantity control component 3 includes a third driving unit 31 and a stop pin 32. The third driving unit 31 is installed on the storage rack 2 below or above the discharge port. The stop pin 32 is installed at the output end of the third driving unit 31 to form a fixed end, and the suspended end of the stop pin 32 faces the discharge port, wherein the third driving unit 31 is used to drive the stop pin 32 to move along the height direction.

[0078] Furthermore, the quantity control component 3 controls the outflow of the pipe fittings to prevent the pipe fittings from piling up on the loading rack 10, and drives the stop pin 32 to move in the height direction through the third driving unit 31, so that the pipe fittings outside the length of the stop pin 32 flow out along the discharge port.

[0079] It is worth noting here that the third driving unit 31 may be a third cylinder.

[0080] In order to prevent the pipe from squeezing the stop pin 32 and causing damage, the third driving unit 31 is generally arranged below the discharge port. During actual operation, the stop pin 32 is driven downward by controlling the third cylinder. At this time, the pipe above the stop pin 32 rolls out of the discharge port not blocked by the stop pin 32 and falls onto the loading rack 10.

[0081] It is worth noting that stop rollers are arranged on both sides of the storage rack 2, so that the bottom layer of pipes in the storage rack 2 will not tilt and can fall smoothly from the storage rack 2.

[0082] In addition, heavy-duty universal brake casters are arranged at the bottom of the storage rack 2, so that it can be easily removed at any time and replaced with a new pipe fitting model.

[0083] Embodiment 3

[0084] refer to Figure 7 This embodiment adopts an automatic feeding device of the second embodiment. This embodiment claims protection for an automatic feeding method, using an automatic feeding device, including:

[0085] In the specific operation of step S1, the third cylinder is controlled to drive the stop pin 32 to move downward. At this time, the bearing surface of the storage rack 2 forms an inclination angle of 2° with the horizontal plane, forming an inclined surface. Under the action of the gravity of the pipe, the pipe automatically falls from the discharge port. The pipe above the stop pin 32 rolls out from the discharge port not blocked by the stop pin 32 and falls onto the loading rack 10.

[0086] In step S2:

[0087] See also Figure 8, one of the pipes that falls on the loading rack 10 enters the first station, triggering the first station monitoring device, and the transmission component 11 lifts the pipe to be transmitted. Secondly, the pipe to be transmitted is pushed from one side of the blocking member 100 to the other side. In fact, this effect can also be achieved by two linear drive devices that are perpendicular to each other. However, the present invention provides a top block 111 on a lifting unit 110. The special shape of the top block 111 cooperates with the blocking effect of the blocking member 100 to fully achieve this effect. It can be imagined that not only the energy loss is reduced, but also the interference and time interval error between the two linear drive devices are avoided. It can be said that two birds with one stone are killed.

[0088] See also Fig. 9 As for how the top block 111 cooperates with the material blocking piece 100, by setting the upper end surface of the top block 111 as an inclined surface inclined downward toward the blocking piece, first, in the initial state, the pipe to be transported is located at the first workstation, and then, when the lifting unit 110 drives the top block 111 to push up, at this time, the top block 111 is not higher than the material blocking piece 100, so the pipe to be transported is located between the top block 111 and the material blocking piece 100 and is in a clamped state, and then, the lifting unit 110 continues to push up, at this time, the top block 111 is higher than the material blocking piece 100, and makes the pipe to be transported higher than the material blocking piece 100, under the action of the inclined surface of the top block 111 and without the obstruction of the material blocking piece 100, the pipe to be transported slides to the other side of the material blocking piece 100.

[0089] See also Fig.10 Finally, the lifting unit 110 moves downward, and when it moves to a position lower than the second station, the pipe to be transported is placed on the rolling bracket 12.

[0090] See also Fig.11 In step S3, the pipe to be transported touches the second station monitoring component. In the initial state, the first drive unit 130 drives the second drive unit 131 away from or close to the pipe to be transported. This setting is mainly to stagger the position of the jacking unit 110 to avoid damage or emergency stop caused by collision or interference. After receiving the signal from the second station monitoring component, the first drive unit 130 is started to fall back and reset to the first roller 132 to contact the pipe to be transported. At this time, the second drive unit 131 is driven to drive the first roller 132 to rotate, and the pipe to be transported is pushed to the third station through the friction force.

[0091] S4. After receiving the monitoring signal from the third station monitoring component, the automatic feeding is completed.

[0092] The present invention also claims protection for an automatic feeding method, which realizes the effect of automatic feeding by cooperating with the transmission component 11, the feeding component 13 and the monitoring components of the corresponding workstations.
