Abstract
Description

[0001] The present application relates to the technical field of rectangular tube processing, and in particular to a material dividing module, a feeding device and processing equipment. Background Art
[0002] At present, due to the large market demand for rectangular tubes, rectangular tubes account for a large proportion of the tubes processed by tube cutting equipment (saws, plasma tube cutters, laser tube cutters, etc.). In order to improve the feeding efficiency of rectangular tubes, there are feeding devices specifically used for rectangular tube feeding on the market.
[0003] During the loading process of rectangular tubes, it is necessary to separate a single rectangular tube from a pile of rectangular tubes, so as to facilitate the processing of rectangular tubes one by one. Separating a single rectangular tube from a pile of rectangular tubes usually includes the following steps: the first step is to stack multiple layers of rectangular tubes on the lifting member; the second step is to raise the height of a rectangular tube to lift the top layer of rectangular tubes to the material separation position; the third step is to move the pusher forward by the width of a rectangular tube, so that the top layer of rectangular tubes moves forward as a whole. At this time, the frontmost rectangular tube falls because it loses the support of the lifting member, thus completing the material separation; the fourth step is to repeat the third step until the top layer of rectangular tubes is completely separated; the fifth step is to repeat the second step, the third step and the fourth step until all the rectangular tubes stacked on the lifting member are completely separated.
[0004] In the related art, the structural design of the feeding device is imperfect. When two adjacent rectangular tubes are stuck together due to oil or water, the front rectangular tube may fall with the rear rectangular tube during the falling process, which will cause the material separation failure and thus affect the feeding efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0051] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.
[0052] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0053] Reference Figure 1 and Figure 2 It should be noted that, since the four corners of the actual rectangular tube 100 are not ideal right angles but rounded corners, the length l of the diagonal of the outer contour of the cross section of the rectangular tube 100 is also the length of the diagonal intercepted by the corresponding two rounded corners. According to the first aspect of the present application, the material distribution module is used for the distribution of the rectangular tube 100, and the height of the outer contour of the cross section of the rectangular tube 100 is set to h, and the length of the diagonal of the outer contour of the cross section of the rectangular tube 100 is set to l, and includes a support member 210, a stop member 220 and a pusher assembly 300.
[0054] The support member 210 is provided with a support surface 212, and the support surface 212 is used to support the rectangular tube 100. The limiting member 220 is provided with a limiting surface 221, and the limiting surface 221 is located above the supporting surface 212, and the limiting surface 221 is used to abut against the upper end of the rectangular tube 100. The distance between the limiting surface 221 and the supporting surface 212 is d, and d satisfies the relationship h<d<l.
[0055] The push assembly 300 includes a push member 310 and a first driving unit 320. The first direction is assumed to be a horizontal direction (refer to Figure 1, for example, the first direction is the left direction), the first driving unit 320 is used to drive the pushing member 310 to move along the first direction, so that at least two rectangular tubes 100 whose width directions are arranged along the first direction are separated from the supporting surface 212 one by one and fall down; the second direction is opposite to the first direction (refer to Figure 1 , for example, the second direction is a rightward direction), the first driving unit 320 is further used to drive the pushing member 310 to move along the second direction.
[0056] The material dividing module according to the embodiment of the present application has at least the following beneficial effects: for two adjacent, adhered rectangular tubes 100, when one rectangular tube 100 is separated from the supporting surface 212 and falls downward, since the distance d between the limiting surface 221 and the supporting surface 212 is less than the length l of the diagonal line of the outer contour of the cross section of the rectangular tube 100, when the other rectangular tube 100 is driven and turned over (refer to Figure 3 ), the limiting surface 221 can abut against the upper end of the rectangular tube 100 (for example, the limiting surface 221 abuts against a rounded corner of the rectangular tube 100), thereby promoting the separation of the two adhered rectangular tubes 100, and the two rectangular tubes 100 will not fall at the same time, thereby improving the problem of failure of material separation due to adhesion of the rectangular tube 100.
[0057] Specifically, the first driving unit 320 can be a cylinder, an oil cylinder, a linear motor, or a gear rack mechanism driven by a motor (see Figure 1 ), one of a motor-driven screw-nut mechanism, a motor-driven synchronous belt and synchronous wheel mechanism, and a motor-driven sprocket and chain mechanism.
[0058] Reference Figure 3 , briefly explain the influence of the distance d between the limiting surface 221 and the supporting surface 212 on the material distribution effect. For the convenience of explanation, the guide surface 211 is introduced in advance (the specific structure of the guide surface 211 is described below). Figure 3 This is an example of two rectangular tubes 100 being adhered, and one rectangular tube 100 is flipped with the other rectangular tube 100. The bottom surface of the rectangular tube 100 on the right is in contact with the guide surface 211, and a diagonal line of the rectangular tube 100 on the left is perpendicular to the horizontal plane. It should be noted that when a rectangular tube 100 is flipped to a point where a diagonal line is perpendicular to the horizontal plane (refer to Figure 3 ), the flipping amplitude of the rectangular tube 100 is the largest.
[0059] In the actual feeding process, the turning range of a rectangular tube 100 may not reach the maximum range. Figure 3 illustrate, Figure 3 The guide surface 211 in the figure is an inclined surface. When the bottom surface of a rectangular tube 100 located on the right side is in contact with the guide surface 211, Figure 3When the angle between the guide surface 211 and the horizontal plane becomes smaller, the turning range of the rectangular tube 100 on the left side will become smaller. At this time, if the limiting surface 221 is to complete the separation of the two rectangular tubes 100, the height of the limiting surface 221 must be reduced.
[0060] That is, when the value of the distance d between the limiting surface 221 and the supporting surface 212 is slightly less than l, the limiting surface 221 may only play a role in separating some rectangular tubes 100 with the largest flipping amplitude, and when the flipping amplitude of the rectangular tube 100 is not the largest, the limiting surface 221 cannot play a role in separating. Therefore, setting the value range of the distance d between the limiting surface 221 and the supporting surface 212 to (h, l) can still improve some adhesion problems, although the effect is not optimal.
[0061] Reference Figure 1 and Figure 2 In some embodiments of the present application, d satisfies the relationship h<d<(h+a)<l, and a satisfies the relationship 10≤a≤20, wherein the units of a, d, h and l are all millimeters.
[0062] a satisfies the relationship 10≤a≤20, that is, the value of d is only 10 to 20 mm greater than h. Since the height h of the common rectangular tube 100 ranges from 60 mm to 400 mm, 10 to 20 mm is only a relatively small value relative to the height h of the rectangular tube 100. Therefore, when d satisfies the relationship h<d<(h+a)<1, and a satisfies the relationship 10≤a≤20, the limiting surface 221 can separate the adhered rectangular tubes 100 in most cases, and the separation effect of the limiting surface 221 is better.
[0063] Specifically, the value of a can be 10 mm, 12 mm, 15 mm, 18 mm, 20 mm or other values.
[0064] Reference Figure 4 In some embodiments of the present application, the distance d between the limiting surface 221 and the supporting surface 212 can be adjusted.
[0065] By adjusting the distance d between the limiting surface 221 and the supporting surface 212 , the material distribution module can improve the adhesion problem of rectangular tubes 100 of different sizes, thereby improving the compatibility of the material distribution module.
[0066] Specifically, refer to Figure 4 and Figure 5The material distribution module also includes an adjustment member 230, a frame 400 and a screw. The adjustment member 230 is provided with a waist-shaped hole 231, and the frame 400 is provided with a threaded hole 410. After the screw passes through the waist-shaped hole 231, it is threadedly matched with the threaded hole 410, thereby fixing the adjustment member 230 to the frame 400. The limit member 220 is installed on the adjustment member 230 (the specific installation structure is described below).
[0067] When the distance d between the limit surface 221 and the support surface 212 needs to be adjusted, the screw is loosened and the position of the adjusting member 230 is moved in the up and down direction until the distance d between the limit surface 221 and the support surface 212 reaches the required value. At this time, the screw is tightened to complete the adjustment of the distance d between the limit surface 221 and the support surface 212.
[0068] In another embodiment, the frame 400 may be provided with a plurality of threaded holes 410 along the up and down directions, and the waist-shaped hole 231 may be replaced with a through hole. By cooperating the screws with different threaded holes 410, the position adjustment of the adjusting member 230 can be achieved, thereby achieving the adjustment of the distance d between the limiting surface 221 and the supporting surface 212.
[0069] Reference Figure 4 and Figure 5 In some embodiments of the present application, the support member 210 is provided with a guide surface 211 , the support surface 212 and the guide surface 211 are arranged along the first direction, the guide surface 211 is connected to the support surface 212 , and the guide surface 211 is lower than the support surface 212 .
[0070] The guide surface 211 is lower than the support surface 212, so that the normal falling of the rectangular tube 100 is not affected, and the two adhered rectangular tubes 100 can be separated normally. The support surface 212 and the guide surface 211 are arranged along the first direction, and the guide surface 211 is connected to the support surface 212. After the rectangular tube 100 is separated from the support surface 212, the guide surface 211 can receive the rectangular tube 100, which is conducive to determining the position of the rectangular tube 100 after falling.
[0071] It should be noted that, in order to enable the rectangular tube 100 to move smoothly from the support surface 212 to the guide surface 211 , the support surface 212 and the guide surface 211 are usually connected by an arc surface.
[0072] Reference Figure 4 In some embodiments of the present application, the height of the guide surface 211 gradually decreases along the first direction.
[0073] The height of the guide surface 211 gradually decreases along the first direction, so the rectangular tube 100 dropped on the guide surface 211 can gradually slide down under the action of gravity, thereby automatically completing the movement of the rectangular tube 100, and the conveying structure of the rectangular tube 100 is simpler.
[0074] Reference Figure 4 In an improved solution of the above embodiment, the guide surface 211 includes one or more of an inclined surface, a convex surface and a concave surface.
[0075] The inclined surface, convex surface and concave surface can all achieve the purpose of gradually reducing the height of the guide surface 211 along the first direction, and the surfaces of the inclined surface, convex surface and concave surface are continuous. The rectangular tube 100 slides along the inclined surface, convex surface or concave surface more stably, and the rectangular tube 100 is not easy to separate from the guide surface 211.
[0076] Reference Figure 4 and Figure 5 According to some embodiments of the present application, the material distribution module further includes a lifting assembly 500, and the lifting assembly 500 includes a lifting member 510 and a second driving unit 520. The lifting member 510 is used to support at least two layers of rectangular tubes 100. When the lower surface of a layer of rectangular tubes 100 is higher than or flush with the supporting surface 212, the rectangular tubes 100 of the layer are located in the first position (refer to Figure 4 , Figure 4 The second driving unit 520 is used to drive the lifting member 510 to move in the up-down direction, so that each layer of rectangular tubes 100 supported by the lifting member 510 moves to the first position one by one.
[0077] By using the lifting assembly 500 to move at least two layers of rectangular tubes 100 up layer by layer to the first position, the material distribution module can complete the distribution of batches of rectangular tubes 100, and the material distribution module has a higher distribution efficiency.
[0078] Specifically, the second driving unit 520 can be one of an air cylinder, an oil cylinder, a linear motor, a motor-driven rack and pinion mechanism, a motor-driven screw-nut mechanism, a motor-driven synchronous belt and synchronous wheel mechanism, and a motor-driven sprocket and chain mechanism.
[0079] Reference Figure 5 It should be noted that, in order to facilitate placing the rectangular tubes 100 in batches on the lifting member 510, the left end of the stopper 220 is also rotatably connected to the adjustment member 230 via a hinge 240. When the stopper 220 is in the upright state, the rectangular tubes 100 can be placed in batches on the lifting member 510. When the stopper 220 is in the horizontal state (refer to Figure 5 , Figure 5 When the limiting member 220 is in a horizontal state, the positioning pin 250 passes through the limiting member 220 and the adjusting member 230 at the same time, thereby limiting the rotational movement of the limiting member 220 relative to the adjusting member 230, and the limiting member 220 can play a normal role in dividing the materials.
[0080] Reference Figure 4 and Figure 5In some embodiments of the present application, the material distribution module further includes a sensor 600, which is used to detect the upper surface 110 (refer to Figure 2 ) is the distance b between them.
[0081] By detecting the distance b, it is helpful to accurately determine whether the rectangular tube 100 located at the top layer has moved to the first position. The material distribution module has a higher degree of automation and a higher efficiency in material distribution.
[0082] In an improved solution of the above embodiment, the sensor 600 includes one of an infrared ranging sensor, a laser ranging sensor and an ultrasonic ranging sensor.
[0083] Infrared ranging sensors, laser ranging sensors and ultrasonic ranging sensors can all quickly and accurately measure distance, which helps to improve measurement accuracy and efficiency.
[0084] Reference Figure 6 In some embodiments of the present application, since the rectangular tube 100 is usually long, multiple groups of support members 210, stoppers 220 and pusher assemblies 300 can be provided. Multiple pusher assemblies 300 jointly push a layer of rectangular tube 100, and the force on the rectangular tube 100 is more uniform, and the rectangular tube 100 can move stably. Multiple groups of support members 210 and stoppers 220 are provided, and multiple stoppers 220 jointly act on the flipped rectangular tube 100, and the material distribution effect of the rectangular tube 100 is more stable.
[0085] Specifically, the material dividing module may include two, three or other numbers of supporting members 210 , limiting members 220 and pushing components 300 .
[0086] The feeding device according to the second embodiment of the present application includes a material dividing module and a feeding module 700. The feeding module 700 is used to pick up the rectangular tube 100 located on the guide surface 211, or the feeding module 700 is used to receive the rectangular tube 100 dropped from the guide surface 211. The feeding module 700 is also used to move the rectangular tube 100 to the processing position.
[0087] The feeding device according to the embodiment of the present application has at least the following beneficial effects: by using the above-mentioned material dividing module, the problem of failure of the rectangular tube 100 to divide due to adhesion can be effectively improved, which is beneficial to improving the feeding efficiency of the feeding device.
[0088] Specifically, the loading module 700 may be a multi-axis motion platform or a multi-axis manipulator.
[0089] The processing equipment according to the third embodiment of the present application includes a feeding device and a processing device 800. The processing device 800 is used to process the rectangular tube 100 located at the processing position.
[0090] The processing equipment according to the embodiment of the present application has at least the following beneficial effects: by using the above-mentioned feeding device, it is helpful to improve the processing efficiency.
[0091] Specifically, the processing device 800 may be one of a saw machine, a laser cutting device, a flame cutting device and a plasma cutting device.
[0092] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
