Description

Technical Field

[0001] The present application relates to the field of material transportation, in particular to a material transportation device and a gas cylinder assembly line. Background Art

[0002] During the production process of portable gas cylinders, a "valve expanding" process is required, that is, the valve is sealed to the mouth of the gas cylinder by flaring. In some related technologies, a gas cylinder valve expanding machine has a valve expanding turntable. The outer periphery of the valve expanding turntable is provided with positioning grooves at intervals for receiving gas cylinders. As the valve expanding turntable rotates, the positioning grooves move back and forth between the upstream and downstream conveying lines, so as to receive and send out gas cylinders. During this process, the valve expanding ram above the positioning groove completes the valve expanding of the gas cylinders.

[0003] However, the intervals of the gas cylinders may be uneven during transportation. Therefore, the positioning grooves need to reach the receiving position in advance to wait for the gas cylinders, and the valve expanding turntable needs to rotate intermittently, leaving enough time windows to avoid receiving failures and the situation where some valve expanding rams are vacant. This results in the operation of the valve expanding turntable not being continuous enough and is not conducive to improving the production efficiency of the gas cylinder valve expanding machine. Summary of the Invention

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present application provides a material transportation device and a gas cylinder assembly line.

The first guide plate extends towards the processing equipment. The first guide wheel and the processing equipment are arranged on the same side of the conveying line. The first guide wheel partially extends into the conveying line. The outer periphery of the first guide wheel is provided with a first positioning groove. The first guide wheel can rotate so that a first conveying position for positioning the material is formed between the first positioning groove and the first guide plate, and the first conveying position moves from the conveying line towards the processing equipment. The dimension of the first conveying position in the circumferential direction is larger than the diameter of the material to compensate for the position deviation of the material.

[0006] The material conveying device provided by the present application has at least the following technical effects: As the first positioning groove rotates, a first conveying position that cyclically moves from the conveying line to the processing equipment is periodically formed between the first guide wheel and the first guide plate, thereby transporting the material from the conveying line to the processing equipment. Since the size of the first conveying position in the circumferential direction is larger than the diameter of the material, even if the position of the material on the conveying line is deviated, it can smoothly enter the first conveying position. After that, the first conveying position rotates away from the conveying line, and the material abuts against the side wall of the first conveying position, completing the positioning and calibration of the position during the conveying process, and thus smoothly entering the processing equipment. Therefore, the material conveying device helps to realize the continuous transfer of materials and improve production efficiency.

If the first and second are described only for the purpose of distinguishing technical features, they should not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0030] In the description of the present application, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0031] During the assembly process of a portable gas cylinder, it is necessary to assemble the bottle cap and the bottle body together through an expanding valve. In some related technologies, the gas cylinder expanding valve machine is located downstream of the conveyor line. First, the processing position of the gas cylinder expanding valve machine moves to the docking position, then the conveyor line sends the gas cylinder into the processing position, and then the gas cylinder expanding valve machine rotates to make the next processing position reach the docking position.

[0032] Since there is an interval between the processing positions, the conveying speed of the conveyor line will be higher than the upstream feeding speed of the gas cylinders, so that an interval appears between the originally closely arranged gas cylinders to avoid the gas cylinders hitting the gas cylinder expanding valve machine during the switching of the processing positions. However, there is an error in the distance between the gas cylinders after they are separated. Therefore, a certain redundancy needs to be reserved for the reception of the gas cylinders, that is, the processing position needs to stay at the docking position for a certain time to leave enough time windows, which results in the operation of the expanding valve turntable not being continuous and is not conducive to improving the production efficiency of the gas cylinder expanding valve machine.

[0033] Exemplarily, refer to Figure 1 and Figure 2, According to the material conveying device provided by the present application, it includes a conveying line 110, a first guiding plate 120 and a first guiding wheel 130. The conveying line 110 is used to convey materials (specifically gas cylinders 900 in the figure). One side of the conveying line 110 is used to arrange processing equipment 200. The first guiding plate 120 is arranged on the other side of the conveying line 110. The first guiding plate 120 extends towards the processing equipment. The first guiding wheel 130 and the processing equipment 200 are arranged on the same side of the conveying line 110. The first guiding wheel 130 partially extends into the conveying line 110. A first positioning groove is formed on the outer circumference of the first guiding wheel 130. The first guiding wheel 130 can rotate so that a first conveying position for positioning materials is formed between the first positioning groove and the first guiding plate 120. And the first conveying position moves from the conveying line 110 towards the processing equipment 200. The dimension of the first conveying position in the circumferential direction is larger than the diameter of the material to compensate for the position deviation of the material.

[0034] Figure 3 Further shows the process of the material entering and leaving the first conveying position. With reference to Figure 3 , According to the material conveying device provided by the present application, it has at least the following technical effects: As the first positioning groove rotates, a first conveying position that circulates and moves from the conveying line 110 towards the processing equipment 200 is formed between the first guiding wheel 130 and the first guiding plate 120, thereby transporting the material from the first conveying line 110 to the processing equipment 200. Since the dimension of the first conveying position in the circumferential direction is larger than the diameter of the material, even if the position of the material on the conveying line 110 is deviated, it can smoothly enter the first conveying position. After that, the first conveying position rotates away from the conveying line 110, and the material abuts against the side wall of the first conveying position, completing the positioning and calibration of the position during the conveying process, and thus smoothly entering the processing equipment 200. Therefore, the material conveying device helps to realize the continuous transfer of materials and improve production efficiency.

[0035] It can be understood that the processing equipment 200 adapted to the material conveying device can be a gas cylinder valve expanding machine for expanding the valves of gas cylinders, or other processing equipment 200 with continuous operation requirements. The present application does not limit this.

[0036] With reference to Figure 4 , The present application also provides a gas cylinder assembly line, which includes a gas cylinder valve expanding machine and the material conveying device provided by the present application.

[0037] Specifically with reference to Figure 2 and Figure 4, in some embodiments, the gas cylinder valve expanding machine includes a valve expanding turntable 210 which has processing positions arranged in an array. Above the processing positions, there is a valve expanding pressure head 220 that can rotate following the valve expanding turntable 210. During the rotation, the gas cylinder 900 gradually loses the limiting block of the first guide plate 120. At the same time, the valve expanding pressure head 220 descends, positions the gas cylinder 900 by expanding the valve of the gas cylinder 900, so that the gas cylinder 900 is transferred from the conveying position to the processing position.

[0038] Due to having a material conveying device, the gas cylinder assembly line accordingly also has the beneficial effects provided by the material conveying device, which will not be elaborated here.

[0039] It should be noted that, as mentioned before, when applied to expanding the valve of a gas cylinder, the conveying speed of the conveying line 110 is greater than the conveying speed of the upstream incoming materials, so as to separate the gas cylinders 900 that were originally closely arranged and conveyed together through the speed difference, facilitating the positioning of the gas cylinders 900 in the first positioning grooves of the first guide wheels 130 and avoiding bad conditions caused by collisions between the gas cylinders 900 and the first guide wheels 130.

[0040] In addition, in some embodiments, the processing device 200 has a turntable, and the processing positions are arranged in an array in the circumferential direction. The linear speed of the conveying position is equal to the linear speed of the processing position, so as to ensure the stable handover of the gas cylinder 900 between the conveying position and the processing position.

[0041] Of course, in addition to the turntable-type processing device 200, the material conveying device can also be applied to a rotary processing device 200 connected end to end. As long as the linear speed of the conveying position is equal to the linear speed of the processing position, ensuring that the gas cylinder 900 can be transferred from the conveying position to the processing position in a relatively static state within a certain time period, this application does not limit this.

[0042] Returning to the material conveying device, it can be understood that at first, the gas cylinder 900 moves under the conveying of the conveying line 110. As the movement route of the gas cylinder 900 deviates from the conveying direction of the conveying line 110, the first guide wheel 130 pushes the gas cylinder 900, thereby providing the gas cylinder 900 with a speed component in other directions.

[0043] To make the first guide wheel 130 more reliably push the gas cylinder 900, optionally, in some embodiments, the first positioning groove can accommodate at least half of the material (here it is the gas cylinder 900). Thus, the first conveying position can more fully surround the gas cylinder 900 and prevent the gas cylinder 900 from slipping out.

[0044] Further, referring to Figure 5 , in some embodiments, the first positioning groove includes a supporting surface 131, the normal direction of the supporting surface 131 is along the tangential direction of the first guide wheel 130, and the supporting surface 131 is used to push the material to move.

[0045] It can be understood that the normal direction of the supporting surface 131 determines the direction of the force exerted by the first positioning groove on the gas cylinder 900. If the normal direction is more outward compared to the tangential direction, a radially outward component force will be generated, increasing the frictional force between the gas cylinder 900 and the first guiding plate 120 and affecting the surface quality of the gas cylinder 900. If the normal direction is more inward compared to the tangential direction, a radially inward component force will be generated, making it easy for the gas cylinder 900 to collide with the first guiding wheel 130 when the gas cylinder 900 is transferred to the processing position and hindering the transfer of the gas cylinder 900. Making the normal direction of the supporting surface 131 along the tangential direction can avoid such problems.

[0046] In some embodiments, the first positioning groove further includes a guiding surface 132. The guiding surface 132 extends smoothly in the circumferential direction, and the diameter of the guiding surface 132 gradually increases in the rotational direction. Refer to Figure 3 , which can reduce the collision between the gas cylinder 900 and the first positioning groove during the conveying process of the gas cylinder 900 and improve the surface quality of the gas cylinder 900.

[0047] After the processing equipment 200 finishes processing the material, the processing equipment 200 needs to continue to convey the material to the next process. Optionally, at this time, the conveying line 110 can be reused, thereby improving the functionality of the material conveying device and simplifying the complexity of the production line.

[0048] Exemplarily, in some embodiments, the material conveying device further includes a second guiding plate 140 and a second guiding wheel 150. The second guiding plate 140 and the second guiding wheel 150 are used to receive the material from the processing position.

[0049] Refer to Figure 2 , specifically, one end of the conveying line 110 is docked with the upstream, the other end of the conveying line 110 is docked with the downstream, and a second positioning groove is formed between the second guiding wheel 150 and the second guiding plate 140. The gas cylinder 900 is returned to the conveying line 110 through the second positioning groove, and the gas cylinder 900 moves downstream along the conveying line 110 again.

[0050] It should be noted that in the Figure 2 implementation, the second guiding wheel 150 and the first guiding wheel 130 have the same structure, and the second guiding plate 140 and the first guiding plate 120 have the same structure, which can reduce the number of parts and facilitate the manufacturing, management, and maintenance of the material conveying device. However, since the second guiding wheel 150 receives the gas cylinder 900 that has been accurately positioned by the processing equipment 200, at this time, the second guiding wheel 150 can also use a conventional star-shaped turntable, which is not limited here.

[0051] In some embodiments, the material conveying device further includes a pallet 160. The pallet 160 and the processing device 200 are arranged on the same side of the conveying line 110. The pallet 160 is located between the processing device 200 and the conveying line 110 and is flush with the conveying line 110. The pallet 160 is used to support the material leaving the conveying line 110.

[0052] In some embodiments, the material conveying device further includes a first baffle 170 and a second baffle 180 extending along the conveying line 110. The first baffle 170 and the processing device 200 are arranged on the same side of the conveying line 110. The first guide wheel 130 is located between the first baffle 170 and the first guide plate 140. The second baffle 180 is arranged on the other side of the conveying line 110, and the second baffle 180 is connected to the first guide plate 140. The first baffle 170 and the second baffle 180 can prevent the gas cylinder 900 from accidentally deviating.

[0053] Similarly, the material conveying device may further include a third baffle 190. The second guide wheel 150 is located between the third baffle 190 and the second guide plate 140 to prevent the gas cylinder 900 from accidentally deviating.
