[0001] The utility model relates to a round pipe unloading buffering technical field, specifically, a kind of round pipe production offline buffering device. BACKGROUND

[0002] In modern manufacturing industry, the production and transportation process of round pipe needs efficient, stable buffering device to cope with the fluctuation of production line and improve overall efficiency.

[0003] Traditional need to set three groups of parallel and interval distribution horizontal buffering chain, while equidistantly set several limit rods on horizontal buffering chain in turn to transfer the round pipe conveyed by roller way to horizontal buffering chain and transfer to next processing site along with horizontal buffering chain, there is often the problem of large horizontal buffering chain horizontal area (the length of occupied area is about 6M, the width of occupied area is 3.5-4M), and the occupied area of buffering device needs to be reduced, and the process of horizontal buffering chain cooperating with limit rod to transfer round pipe on roller way lacks round pipe position detection assembly, so that the phenomenon of round pipe not completely contacting limit rod and limit rod moving in advance occurs, at this time, round pipe is prone to fall, and the feeding effect of round pipe to buffering chain needs to be improved. UTILITARIAN CONTENT

[0004] The utility model aims at solving the problem in the above background art, and further provides a kind of round pipe production offline buffering device.

[0005] The technical scheme adopted by the utility model to solve its technical problems is:

[0006] A kind of round pipe production offline buffering device, including roller way and drive assembly, further including vertical transmission chain, detection assembly, flexible buffer, receiving slot, installation platform and photoelectric opposite switch,

[0007] Three parallel equidistant vertical transmission chains are fixed on installation platform and are linked by drive assembly;

[0008] Detection assembly is arranged in the end region of roller way and is at the front side of the most remote vertical transmission chain to immediately transmit signal to start vertical buffering lifting after detecting that round pipe front end moves to the position where detection assembly is;

[0009] Several flexible buffers are fixed on the multiple chain links of vertical transmission chain;

[0010] Receiving slot is opened on flexible buffer to accommodate round pipe;

[0011] Photoelectric opposite switch is fixed on installation platform and is opposite to one of flexible buffers and is electrically connected with drive assembly.

[0012] Furthermore, the detection component includes a baffle and a non-contact sensor.

[0013] The baffle is fixed at the end area of ​​the roller conveyor, and a non-contact sensor is fixed on the baffle facing the forward path of the circular tube conveyor.

[0014] Furthermore, the detection component includes a baffle, a pressure sensor, and a rubber layer. The baffle is fixed in the end area of ​​the roller conveyor, and a pressure sensor is fixed on the baffle facing the forward path of the circular tube conveyor.

[0015] The rubber layer is fixed to the contact surface of the pressure sensor.

[0016] Furthermore, the conveying speed of the vertical transmission chain is greater than the conveying speed of the roller conveyor.

[0017] Furthermore, there is an empty chain section between the chains installed on two adjacent flexible buffer components.

[0018] Furthermore, a mounting plate is fixed to the bottom of several of the flexible buffer components of different sizes, and the mounting plate is movably mounted to the chain.

[0019] Furthermore, a suction pipe is fixed along the length of the roller conveyor, and several branch pipes are provided on the suction pipe above the roller conveyor. The suction pipe is connected to a suction pump, and the suction pump is connected to a gas-liquid separation device.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This application uses a vertical drive chain for transferring round tubes. The length of the deployment area is 6 meters, and the width of the deployment area is 1-1.5 meters, which significantly reduces the horizontal footprint. At the same time, during the feeding process of the round tube into the receiving groove of the flexible buffer component on the vertical drive chain, the front end position can be accurately known. When the front end of the round tube is detected by the detection component, the vertical buffer chain is immediately triggered to lift the round tube. This prevents the round tube from falling off before it has completely passed through the three flexible buffer components in a horizontal row, which would otherwise cause the flexible buffer components to move prematurely. Therefore, the feeding efficiency of the round tube onto the buffer chain needs to be improved. By utilizing three-dimensional space and dynamic buffer adjustment, this application breaks through the traditional planar buffering method and adopts a three-dimensional chain structure to make full use of vertical space, greatly increasing the buffering capacity.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0028] like Figure 1 and Figure 2 As shown, a buffer device for a round tube production line includes a roller conveyor 1 and a drive assembly (both are prior art and their working principles are not described), as well as a vertical transmission chain 3, a detection assembly 2, a flexible buffer 4, a receiving trough 5, a mounting platform 6, and a photoelectric beam switch 7.

[0029] Three parallel and equidistant vertical transmission chains 3 are fixed on the mounting platform 6 and linked by the drive assembly.

[0030] The detection component 2 is located at the end of the roller conveyor 1 and in front of the farthest vertical transmission chain 3 so that it can immediately transmit a signal to start vertical buffer lifting after detecting that the front end of the round tube has moved to the position of the detection component 2.

[0031] Several flexible buffer components 4 are fixed on the multi-section chain of the vertical transmission chain 3;

[0032] The receiving slot 5 is formed on the flexible buffer 4 to accommodate the round tube;

[0033] The photoelectric through-beam switch 7 is fixed on the mounting platform 6 and faces one of the flexible buffers 4 and is electrically connected to the drive assembly.

[0034] First embodiment:

[0035] In a specific implementation of the first embodiment of this utility model, the detection component 2 includes a baffle 8 and a non-contact sensor.

[0036] The baffle 8 is fixed at the end area of ​​the roller conveyor 1, and a non-contact sensor facing the forward path of the circular tube is fixed on the baffle 8. The non-contact sensor is either a distance sensor or a laser displacement sensor. In this embodiment, when the distance between the front end of the circular tube and the non-contact sensor reaches a preset value range, the non-contact sensor feeds back a signal to the controller, thereby stopping the vertical transmission chain 3.

[0037] To reduce the interference of water vapor on the non-contact sensor, the above embodiment is further optimized by fixing a suction pipe 9 along the length of the roller conveyor 1. The suction pipe 9 is provided with several branch pipes above the roller conveyor 1 and the suction pipe 9 is connected to a suction pump. The suction pump is connected to a gas-liquid separation device. Neither the suction pump nor the gas-liquid separation device is shown in the figure. The gas-liquid separation device is existing technology and is not improved.

[0038] Second embodiment:

[0039] In a specific implementation of the second embodiment of this utility model, the detection component 2 includes a baffle 8, a contact sensor, and a rubber layer.

[0040] The baffle 8 is fixed in the end area of ​​the roller conveyor 1, and a contact sensor facing the forward path of the circular tube is fixed on the baffle 8.

[0041] The rubber layer is fixed on the contact surface of the contact sensor. Specifically, the contact sensor is either a limit switch or a pressure sensor. In this embodiment, when the front end of the round tube comes into contact with the contact sensor, the contact sensor immediately sends a feedback signal to the controller, and then the controller controls the vertical transmission chain 3 to stop. The rubber layer can extend the service life of the contact sensor.

[0042] In order to ensure that the round tubes are effectively fed into the storage slots 5 on the different flexible buffers 4 of the vertical transmission chain 3 and stored independently at intervals, the above embodiment is further refined by the transmission speed of the vertical transmission chain 3 being greater than the transmission speed of the roller conveyor 1, and the chains installed on the two flexible buffers 4 being spaced apart by a section of empty chain.

[0043] In order to facilitate the easy assembly and disassembly of the flexible buffer 4 and the chain to meet the buffering needs of round tubes of different diameters and lengths, the above embodiment is further optimized. The bottom of several flexible buffers 4 of different sizes is fixed with a mounting plate, and the mounting plate and the chain are movably installed. The storage groove 5 on the flexible buffers 4 of different sizes is also different in size to accommodate the storage needs of round tubes with larger diameters.

[0044] The working process of this utility model:

[0045] First, the round tubes that have been washed are transported one by one through the roller conveyor 1. Initially, the vertical transmission chain 3 is driven by the drive component. When one of the flexible buffers 4 moves to the position directly opposite the photoelectric photoelectric switch 7, the photoelectric photoelectric switch 7 sends a signal to the controller. The controller then controls the drive component to stop immediately, thus accurately defining the position of the flexible buffer 4 (that is, the receiving grooves 5 on the three flexible buffers 4 that are in a horizontal row and directly opposite each other can allow the round tubes transported by the roller conveyor 1 to pass through).

[0046] Then the round tube on roller conveyor 1 will pass through the three receiving grooves 5 in sequence and continue to move forward. When the front end of the round tube is limited and detected by the detection component 2, the detection component 2 will send a feedback signal to the controller. The controller will then control the vertical transmission chain 3 to move and lift the round tube. Then when the photoelectric photoelectric switch 7 detects that the next flexible buffer 4 has moved to its corresponding position, it will send a feedback signal to the drive component again. At this time, the vertical chain transmission component will stop again. By repeating the above process, several round tubes can be vertically lifted and transferred in sequence. Then, as the vertical transmission chain 3 continues to move, the round tube will eventually move to the unloading side of the vertical transmission chain 3 and leave the receiving groove 5 one by one to be transported to the next process for subsequent processing.

[0047] When using a vertical transmission chain 3 to transfer the round tube, the length of the deployment area is 6M and the width of the deployment area is 1-1.5M, which can significantly reduce the horizontal footprint. At the same time, during the feeding process of the round tube into the receiving groove 5 on the flexible buffer 4 of the vertical transmission chain 3, the front end position can be accurately known. When the front end of the round tube is detected by the detection component 2, the vertical buffer chain will be immediately triggered to lift the round tube, so that the round tube will not fall off before the three flexible buffers 4 in a horizontal row move prematurely. Therefore, the feeding effect of the round tube onto the buffer chain needs to be improved.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
