Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to pipe feeding equipment. Background Technology

[0002] To improve production efficiency and processing speed, laser tube cutting machines are equipped with automatic feeding racks that continuously supply tubes to the laser cutting machine without manual intervention. Existing automatic feeding racks typically arrange multiple tubes placed in a feeding assembly onto a discharging assembly. A lifting assembly separates one tube from the multiple tubes, and a pushing assembly then pushes this tube into the subsequent laser tube cutting machine. In actual production, tube jamming is particularly prone to occur when the tubes are conveyed to the discharging assembly for arrangement, especially between the feed chute and the limit adjustment plate. This necessitates machine shutdown for troubleshooting, disrupting the production rhythm of automated production.

[0003] Patent No. CN202411055247.3 discloses an automatic continuous pipe cutting device, including a side hanger, a gantry frame, a laser cutting component, a rear chuck component, a front chuck component, an automatic feeding rack, and a receiving rack. The automatic feeding rack includes at least three sets of spaced-apart rack modules. Each rack module includes a base frame, a corner frame mounted on the base frame, a sorting area at the top corner of the corner frame, a first baffle component for intercepting and releasing pipes in the sorting area, and a sorting component for separating multiple pipes in the sorting area into single pipes. The corner frame is equipped with an inlet inclined bar and an outlet inclined shaft. The outlet inclined shaft and the first baffle component work together to form an open sorting area. The material conveying component only needs to pull multiple pipes to the sorting area. The pusher bar and stacking pusher block of the sorting component work together to accurately sort multiple irregularly placed pipes in the sorting area into single pipes, solving the problem of material jamming. When feeding thin-walled and long pipes, which are relatively soft, two pipes may cross during the feeding process. After the crossed pipes enter the distribution area 13, the distribution area 13 is U-shaped with the opening facing upwards, and the pipe ends have little room to move, which may cause jamming. The distribution component 3 cannot push the crossed and stacked pipes back into the storage area 41. At this time, the machine needs to be stopped for manual adjustment, which is inefficient. Therefore, this utility model proposes a pipe feeding device. Utility Model Content

[0004] The main purpose of this utility model is to provide a pipe feeding device that can automatically adjust itself when pipes cross, so that all the crossing pipes are returned to the material storage conveying unit to prevent jamming, without the need for manual adjustment.

[0005] This utility model proposes a pipe feeding device, comprising: a hopper conveying unit, a blocking unit, and a discharging unit arranged along a first horizontal direction. The hopper conveying unit and the discharging unit are connected front and rear, forming a recessed distribution area at the connection position that can only accommodate a single pipe. The hopper conveying unit delivers multiple pipes to the distribution area, and the blocking unit allows the pipes to pass through the distribution area one by one. The device is characterized in that: a distribution component is provided on one side of the distribution area, the distribution component including a distribution plate located on the side of the distribution area and a drive mechanism for driving the distribution plate to move obliquely back and forth, and a blocking rod is provided at the end of the lower end face of the distribution plate.

[0006] Preferably, the material conveying unit includes multiple material conveying components arranged side by side along the second horizontal direction, the material blocking unit includes material blocking components corresponding to the material conveying components, and the material discharging unit includes material discharging components corresponding to the material conveying components. The material conveying components, their corresponding material blocking components, material consolidation components, and material discharging components form a working module. Each working module is independently set on a support, and the material distribution area is located at the highest point of the support. The second horizontal direction is perpendicular to the first horizontal direction.

[0007] Preferably, the discharge assembly includes an outlet inclined shaft disposed on the support, and the inlet of the outlet inclined shaft is located in the material distribution area.

[0008] Preferably, the material conveying assembly includes a conveyor belt, a tightening wheel, a servo motor, a support block, and a column. The servo motor is located at the lower part of the support, and the column is located on the side of the support away from the material distribution area. The servo motor drives the tightening wheel to rotate around a second horizontal direction. The support block is rotated around the second horizontal direction and located at the lower part of the material distribution area. One end of the conveyor belt is wrapped around the tightening wheel, and the middle part of the conveyor belt is supported on the support block. The other end of the conveyor belt is connected to the column and installed at a height higher than the support block. A material sinking space is formed between the column and the support block.

[0009] Preferably, the bottom of the material storage conveying unit is provided with a material straightening unit, and the material straightening assembly includes a material straightening plate provided on the support below the fabric belt, and the upper end surface of the material straightening plate is provided as a first inclined surface facing the side where the tightening wheel is located.

[0010] Preferably, a pusher assembly is connected to the fabric belt. The pusher assembly includes a pusher block located on the upper surface of the fabric belt and a clamping plate located on the lower surface of the fabric belt. The clamping plate and the pusher block are fixed to the fabric belt by bolts.

[0011] Preferably, the upper surface of the pusher block is a second inclined surface, with the lower end of the second inclined surface facing the side where the column is located, and a protruding ridge extending along its length is provided on the second inclined surface.

[0012] Preferably, the material blocking assembly includes a material blocking member rotatably mounted on the bracket about a second horizontal direction and a driving member for driving the material blocking member to rotate, wherein the material blocking member is higher than the material distribution area when it rotates to its highest point.

[0013] Preferably, it also includes a material distribution space adjustment component, which includes a slide plate, a slide rail, a lead screw, and a drive motor. The slide rail is mounted on the bracket and guides the slide plate to slide obliquely. The drive motor drives the lead screw to rotate. The lead screw is threadedly engaged with the slide plate. The axis of the lead screw is parallel to the length direction of the slide rail. The material distribution area is formed by the upper surface of the raised slide plate and the material stop member raised to the highest point.

[0014] The beneficial effects of this utility model's technical solution are:

[0015] When the material hopper conveying unit pulls the pipe to the sorting area and resets, the drive mechanism drives the sorting plate to retract and then push it out again. If the two pipes at the front cross and get stuck, during the process of the sorting plate retracting and pushing it out again, the first pipe in the sorting area will shake and separate from the pipe behind it. The pipe behind it will then retreat under the action of the material hopper conveying unit, so that only a single pipe is left in the sorting area. This achieves self-adjustment when stuck, eliminating the need for manual adjustment by stopping the machine, and greatly improving work efficiency.

[0016] By setting a material straightening component below the material hopper conveying component, each time the material hopper conveying component releases the pipes on the conveyor belt downwards, the pipes will slide and roll down along the first inclined surface after the conveyor belt contacts the first inclined surface, thereby straightening the pipes, separating the intersecting pipes, reducing the probability of pipe intersection, and improving the success rate of material loading.

[0017] The conveyor belt is equipped with a pusher block. When there is only a very small amount of pipe left on the conveyor belt, the conveyor belt can push the pipe against the pusher block to pull it, ensuring that the pipe can be smoothly pulled to the distribution area.

[0025] The present invention will be further described in detail below with reference to specific embodiments.

[0026] Example:

[0027] like Figure 1 and Figure 2 As shown, the pipe feeding device of this utility model includes: a material hopper conveying unit 1, a material blocking unit 2, and a material discharging unit 3 arranged along a first horizontal direction. The material hopper conveying unit and the material discharging unit 3 are connected front to back and form a material distribution area 23 at the connection position. The material hopper conveying unit delivers multiple pipes to the material distribution area. The material blocking unit 2 makes the pipes pass through the material distribution area one by one. A material distribution component is provided on one side of the material distribution area. The material distribution component includes a material distribution plate 4 located on the side of the material distribution area and a first cylinder 5 that drives the material distribution plate 4 to reciprocate. The top rod of the first cylinder 5 is fixed with a connecting block 24. The material distribution plate 4 is slidably connected to the connecting block 24. The material distribution plate 4 is fixed to the connecting block 24 by fastening bolts. A material blocking rod 6 is provided at the end of the lower end face of the material distribution plate 4.

[0028] The material conveying unit includes multiple material conveying components arranged side by side along the second horizontal direction. The material preparation unit includes multiple material preparation components that correspond one-to-one with the material conveying components. The material blocking unit 2 includes material blocking components that correspond one-to-one with the material conveying components. The material discharging unit 3 includes material discharging components that correspond one-to-one with the material conveying components. The material conveying components, their corresponding material blocking components, material preparation components, and material discharging components form a working module. Each working module is independently set on a support 7 and the material distribution area is located at the highest point of the support 7. The second horizontal direction is perpendicular to the first horizontal direction.

[0029] The discharge assembly includes an output inclined shaft 8 mounted on a support 7, with the inlet of the output inclined shaft 8 located in the material distribution area.

[0030] The material conveying assembly includes a belt 9, a tensioning wheel 10, a servo motor 25, a support block 26, and a column 11. The servo motor 25 is located at the lower part of the support 7, and the column 11 is located on the side of the support 7 away from the material distribution area. The servo motor drives the tensioning wheel 10 to rotate around the second horizontal direction. The support block 26 is located at the lower part of the material distribution area 23. One end of the belt 9 is wrapped around the tensioning wheel 10, and the middle part of the belt is supported on the support block 26. The other end of the belt 9 is connected to the column 11, and its installation height is higher than that of the support block 26. A material sinking space is formed between the column 11 and the support block 26.

[0031] The bottom of the material conveying unit 1 is provided with a material straightening unit, which includes a material straightening plate 12 located on the support below the fabric belt. The upper end surface of the material straightening plate is a first inclined surface 13 facing the side where the tensioning wheel is located.

[0032] A pusher assembly is connected to the fabric belt 9. The pusher assembly includes a pusher block 14 located on the upper surface of the fabric belt 9 and a clamping plate 15 located on the lower surface of the fabric belt 9. The clamping plate 15 and the pusher block 14 are fixed to the fabric belt 9 by bolts.

[0033] The upper surface of the pusher block 14 is set as the second inclined surface 16, with the lower end of the second inclined surface 16 facing the side where the column 11 is located.

[0034] The second inclined surface 16 is provided with a protruding ridge 17 extending along its length.

[0035] The material blocking assembly includes a material blocking element 18 rotatably mounted on a bracket 7 about a second horizontal direction, the material blocking element 18 and a second cylinder 19 that drives the material blocking element 18 to rotate. When the material blocking element 18 rotates to its highest point, it is higher than the material distribution zone 23.

[0036] It also includes a material distribution space adjustment component, which includes a slide plate 20, a slide rail, a lead screw 21, and a drive motor 22. The slide rail is mounted on the bracket and guides the slide plate 20 to slide obliquely. The drive motor 22 drives the lead screw 21 to rotate. The lead screw 21 is threadedly engaged with the slide plate 20. The axis of the lead screw 21 is parallel to the length direction of the slide rail. The material distribution area 23 is formed by the upper surface of the raised slide plate 20 and the material stop 18 raised to the highest point.

[0037] The upper end face of the baffle 18 is provided with a groove, and a pressure rod is connected in the groove. A pressure sensor is connected to the bottom end of the pressure rod. When the pipe comes into the material distribution area 23, the pressure rod is pressed, and the pressure sensor detects the pressure change, thereby detecting whether material has arrived.

[0038] Initial state of the feeding equipment: The push rod of the first cylinder 5 extends, causing the material distribution plate 4 to extend above the material distribution area. A temporary storage slot with an upward opening is formed between the baffle rod 6 and the material distribution area 23. The temporary storage slot can only accommodate a single pipe, and multiple pipes are stacked on the cloth belt 9.

[0039] The working process of this utility model is as follows: the servo motor drives the tensioning wheel 10 to wind up the cloth belt 9, thereby pulling the pipes stacked on the cloth belt 9 upward and causing the pipes at the front end to rush into the material distribution area.

[0040] The servo motor drives the belt 9 to reset, causing the remaining pipes to sink into the sinking space. At the same time, the push rod of the first cylinder 5 retracts and then extends, completing one material distribution action. The friction between the baffle rod 6 and the foremost pipe causes it to vibrate, thereby separating the first pipe in the distribution area 23 from the pipes behind it. When the pipes are stacked crosswise, the temporary storage slot is released when the push rod of the first cylinder 5 retracts for the first time. The movement space at the end of the pipe can prevent the end of the pipe from getting stuck. The crosswise pipes are pushed back into the material storage conveying unit 1 under the action of the friction of the belt 9 and the weight of the pipes, so that there is no need to stop the machine for manual adjustment, which greatly improves the work efficiency.

[0041] The push rod of the first cylinder 5 retracts, and the second cylinder 19 drives the baffle 18 to rotate clockwise, releasing the single pipe in the material distribution area 23. The pipe slides out along the guide inclined axis 8.

[0042] The second cylinder 19 drives the material stop 18 to reset, and the first cylinder 5 drives the material distribution plate 4 to reset.

[0043] Repeat the above steps to achieve continuous feeding.

[0044] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
