Abstract
Description
Technical Field
[0001] This utility model relates to a buffer unloading device for pipe fittings, and more particularly to a pipe fitting unloading device used in conjunction with an AGV trolley. Background Technology
[0002] During the manufacturing process of pipe fittings, finished or semi-finished products need to be transferred from the production line. Generally, the finished pipe fittings are temporarily stored in a buffer rack equipped with a pre-process connection mechanism. The pre-process connection mechanism first transfers the pipe fittings from the production line to the buffer rack, and then the workpieces are transferred to other places by handling machinery such as cranes, forklifts, AGVs (Automated Guided Vehicles).
[0003] Currently, AGVs (Automated Guided Vehicles), or intelligent material handling robots, are increasingly being used to perform the aforementioned transfer tasks. However, a single AGV has a limited capacity for carrying a single load. Existing buffer racks are designed to address the issue that the number of pipes temporarily stored on the rack often does not match the carrying capacity of the AGV. Therefore, to avoid exceeding the AGV's carrying capacity, pipes are often transferred one by one from the buffer rack to the AGV. This transfer method is inefficient, impacting handling efficiency and preventing the AGV from fully utilizing its carrying capacity, thus increasing congestion on internal material transport routes. Utility Model Content
[0004] To make more effective use of AGVs for transferring pipe fittings, the technical problem to be solved by the present invention is to provide a pipe fitting unloading device with a quantitative buffer function, which has at least one buffer section. The number of pipe fittings that the buffer section can temporarily store is matched with the carrying capacity of the AGV, so that the pipe fittings in the buffer section can be transferred to the AGV continuously or in one go.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a pipe unloading device with quantitative buffering function, including two or more buffer racks arranged side by side, each buffer rack including an inclined support beam, with a pre-process connection mechanism provided at the higher end of the support beam, and also including an automatic baffle assembly equipped with a baffle component. The baffle component is normally located below the support beam. When a first trigger signal occurs, the automatic baffle assembly is activated, and the baffle component protrudes upward from the support beam, dividing the support beam into a first buffer segment and a second buffer segment. When a second trigger signal occurs, the automatic baffle assembly is activated, and the baffle component returns to its normal state.
[0006] The preceding process connection mechanism is a material turning mechanism, and the first trigger signal is the count value of the number of times the material turning mechanism turns within a certain period of time.
[0007] The pipe unloading device is used in conjunction with the AGV, and the first trigger signal is the loading signal issued by the AGV.
[0008] There are two or more automatic material feeding components, which are spaced apart from each other, dividing the load-bearing beam into three or more buffer sections.
[0009] At least two adjacent buffer racks are equipped with automatic feeder components that are interconnected by a synchronization mechanism.
[0010] There are cases where the height positions of the supporting beams of each buffer rack are different. There is a buffer rack group consisting of two or more continuously arranged buffer racks between at least two non-adjacent buffer racks with the same height position. The height positions of the supporting beams of each buffer rack in the buffer rack group are consistent, and the height positions are lower than the height positions of the supporting beams of the two non-adjacent buffer racks.
[0011] All the load-bearing beams of the buffer racks are at the same height, but the spacing between adjacent buffer racks changes monotonically from one end to the other.
[0012] The beneficial effects of this utility model are: by dividing the bearing beam into at least two buffer sections by the material blocking component, the maximum number of pipes carried in each buffer section is not greater than the number of pipes that the AGV can transfer in a single trip. The material on the buffer rack can be separated into a preset number of pipes before being loaded by the AGV, which improves the material transfer efficiency from the buffer rack to the AGV and avoids affecting the continuous use of the buffer rack due to the loading of the AGV, which is conducive to improving the overall efficiency of the pipe processing system.

[0015] The diagram is labeled as follows: 1-Buffer rack, 2-Pre-process connection mechanism, 4-Synchronization rod, 10-Bearing beam, 31-Blocking component, 32-First connecting rod, 33-Drive cylinder, 101-First buffer section, 102-Second buffer section. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1As shown, the pipe unloading device with quantitative buffering function of this utility model includes two or more buffer racks 1 arranged side by side. The buffer rack 1 includes an inclined support beam 10. The higher end of the support beam 10 is provided with a pre-process connecting mechanism 2, which is a material turning mechanism. It also includes an automatic material blocking component 31. The material blocking component 31 is normally located below the surface of the support beam 10 used to support the pipe. When the first trigger signal occurs, the automatic material blocking component is activated, and the material blocking component 31 protrudes upward from the support beam 10, dividing the support beam 10 into a first buffer section 101 and a second buffer section 102. When the second trigger signal occurs, the automatic material blocking component is activated, and the material blocking component 31 returns to its normal state.
[0018] like Figure 1 As shown, the buffer rack 1 is a commonly used pipe fitting rack, which can be used to support the buffered pipe fittings and provide an installation foundation for the upstream process connection mechanism 2 and the automatic material blocking component; the buffer rack 1 has a load-bearing beam 10, which is inclined and the material blocking component 31 is divided into at least two buffer sections, namely the first buffer section 101 and the second buffer section 102; the first trigger signal can be determined according to the pipe fitting quantity control requirements of the buffer section, while the second trigger signal can be determined according to the automation rhythm of the entire pipe fitting production system.
[0019] The integer part of the quotient obtained by dividing the length of the buffer section by the pipe diameter represents the maximum number of pipes that the buffer section can temporarily store. This number must not exceed the maximum loading capacity of the AGV. Furthermore, considering the situation where pipes in the first buffer section 101 are being transferred to the AGV, the pipes are first stopped by the blocking component 31 in the second buffer section 102. This prevents the pipes from reaching the first buffer section 101 and avoids newly flipped pipes from rolling down the load-bearing beam 10 and interfering with the AGV's loading. Therefore, the count of flipping times by the flipping mechanism 2 over a period of time is considered as the first trigger signal. Simultaneously, if the pipe unloading device is used in conjunction with the AGV, the loading signal issued by the AGV should also be used as the first trigger signal. The signal indicating that the AGV has completed loading and is starting to leave, or a delayed signal based on this signal, can be used as the second trigger signal.
[0020] The pipe fitting unloading device of this utility model is supplemented with a corresponding automated control system to complete the aforementioned automated control process. This process can be accomplished using various existing means, so it will not be described in detail.
[0021] The pipe unloading device of this utility model requires at least two buffer sections. When the AGV is used to load pipes in conjunction with the lower-positioned first buffer section 101, the higher-positioned second buffer section 102 is used to temporarily store the pipes, without affecting the production rhythm of the preceding processing steps. When the first buffer section 101 is empty, the pipes temporarily stored in the second buffer section 102 can be lowered to the first buffer section 101 for transfer. If there are only two buffer sections, when the number of pipes in the second buffer section 102 reaches its maximum, the preceding process connecting mechanism 2 is restricted from operating, which is considered as the entire pipe unloading device reaching its maximum load capacity.
[0022] Based on the aforementioned control objective, it is clear that there can be two or more automatic material blocking components, which are spaced apart from each other, dividing the bearing beam 10 into three or more buffer sections. When the number of pipes in the last buffer section at the highest position reaches the maximum, the preceding process connection mechanism 2 is restricted from operating, which is considered as the entire pipe unloading device reaching its maximum load capacity.
[0023] Since a single pipe fitting requires at least two buffer racks for support, to facilitate synchronous control and simplify the control system, the automatic stop components configured on at least two adjacent buffer racks 1 are interconnected through a synchronization mechanism. This ensures the synchronicity of the rolling of the pipe fitting's two ends along the bearing beam 10, and helps prevent the pipe fitting from shifting and accidentally slipping off the rack during the impact with the stop component 31. The stop component 31 can adopt various designs, and there are also various compatible synchronization implementation methods in the prior art, such as... Figure 1 As shown, a simpler approach is to use a rotatable rod. This rod can rotate within a certain range through the movement of the drive mechanism, thus protruding above or below the load-bearing beam 10. Correspondingly, the synchronization mechanism can use a simple synchronization rod 4.
[0024] The following is a detailed explanation. (Reference) Figure 1 The automatic material-stopping assembly includes a material-stopping component 31, a synchronizing rod 4, a first connecting rod 32, and a driving cylinder 33. The extension direction of the first connecting rod 32 intersects the extension and retraction direction of the driving cylinder 33, thus enabling the synchronizing rod 4 to rotate via the extension and retraction of the driving cylinder 33, thereby moving the synchronizing rod 4 between a first preset position and a second preset position. The synchronizing rod 4 is rotatably mounted on the supporting beam 1. The material-stopping component 31 is mounted on the synchronizing rod 4 and can rotate with the synchronizing rod 4. After the synchronizing rod 4 rotates to the first preset position, the material-stopping component 31 protrudes from the surface of the supporting beam 10 used to support the pipe fitting, preventing the pipe fitting in the second buffer section 102 from rolling towards the first buffer section 101. After the synchronizing rod 4 rotates to the second preset position, the material-stopping component 31 is located below the surface of the supporting beam 10 used to support the pipe fitting, allowing the pipe fitting to roll towards the first buffer section 101 under the influence of gravity.
[0025] Specifically, when the number of pipes in the first buffer section 101 reaches a preset quantity, or when the AGV has arrived and is ready to transfer the pipes from the buffer rack 1 to the AGV, the drive cylinder 33 drives the synchronizing rod 4 to rotate from the second preset position to the first preset position. After the AGV has transferred all the pipes on the first buffer section 101, the drive cylinder 33 drives the synchronizing rod 4 to rotate from the first preset position to the second preset position.
[0026] In a preferred embodiment, during the rotation of the baffle component 31 from the first preset position to the second preset position, the end of the baffle component 31 away from the synchronizing rod 4 deflects toward the lower side of the bearing beam 10. This helps reduce the difficulty of rotating the baffle component 31—if it rotates in the other direction, the fittings on the second buffer section 102 may block the rotation of the baffle component 31.
[0027] In actual production, the diameter and length of pipe fittings may vary, and the processing quantity of pipe fittings of the same specification may also vary. Therefore, the pipe fitting unloading device of this utility model has been improved and adjusted accordingly.
[0028] Example 1:
[0029] like Figure 1 As shown, the pipe unloading device with quantitative buffering function used in the aforementioned pipe processing system includes multiple buffer racks 1 arranged side by side. The supporting beams 10 of all the buffer racks 1 constituting the pipe unloading device are at the same height, but the spacing between adjacent buffer racks 1 changes monotonically from one end to the other. A portion of the racks with smaller spacing can be used for buffering shorter pipes, while a portion of the racks with larger spacing can be used for buffering longer pipes.
[0030] Example 2:
[0031] like Figure 2 As shown, the aforementioned pipe fitting processing system uses a pipe fitting unloading device with a quantitative buffer function, comprising multiple buffer racks 1 arranged side by side. However, the height positions of the supporting beams 10 of each buffer rack 1 are different. At least two non-adjacent buffer racks 1 with the same height position exist as a buffer rack group consisting of two or more consecutively arranged buffer racks 1. The supporting beams of each buffer rack 1 in the buffer rack group have the same height position, and this height position is lower than the height position of the supporting beams of the two non-adjacent buffer racks 1. The two non-adjacent buffer racks with the same height position and the higher one are used for buffering long pipe fittings, and the buffer rack group is used for buffering short pipe fittings.
[0032] The above design can further make the pipe unloading device applicable to more application scenarios, which is conducive to improving the flexibility of the pipe processing production line.
