Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and in particular to a material taking device and a material taking equipment. Background Art

[0002] With the development of automation technology in textile machinery, automatic material picking technology has emerged. The stacked pieces are picked up in layers through an automatic material picking device to ensure that the picked up pieces are in a single-layer state and avoid picking up multiple layers of pieces at a time. The traditional material picking device is a pin-type material picking device, which installs pins on the needle plate and drives the needle plate through a driving mechanism to achieve pin picking. However, many styles of pieces now often have embroidery or patches, which makes the thickness of the pieces uneven. When a certain number of pieces with uneven thickness are stacked, they often form high and low positions, and when the number of pieces continues to decrease, the shape of the piece pile will continue to change. The traditional pin-type material picking device is prone to missing pieces when picking up pieces from a pile of pieces with uneven thickness, especially when the number of stacked pieces is large, it is more difficult to achieve stable layered material picking.

[0034] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0036] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0037] Currently, there are many styles of cut pieces that often have embroidery or patches, such as numbers, letters, patterns, etc., which makes the thickness of the cut pieces uneven, and the thickness is thicker where there are embroidery or patches. When a certain number of such cut pieces are stacked, there are obvious protrusions in the thicker parts of the cut pieces, and the top surface of the cut piece pile forms high and low positions. As the number of cut pieces continues to decrease, the shape of the cut piece pile will continue to change, and the degree of this change is different, making it difficult to derive the law of change. Traditional pin-type material picking devices are prone to missing cut pieces when picking up cut pieces from such stacked cut pieces of uneven thickness, making it difficult to achieve stable layered material picking. Based on this, the present application provides a material picking device and a material picking equipment to avoid missing cut pieces when picking up materials and achieve stable layered material picking.

[0038] See also Figure 1 to Figure 6, the figure shows a schematic structural diagram of a material picking device 2 in an embodiment of the present application. The material picking device 2 provided in an embodiment of the present application comprises a material moving mechanism 20 and a material picking mechanism 21; the driving end of the material moving mechanism 20 is connected to the material picking mechanism 21; the material picking mechanism 21 comprises a material picking driving component 211, a connecting member 212, a pin driving component 213, a needle plate 214, a pin 215, a hinge 216 and a roller 217, the driving end of the material picking driving component 211 is connected to the connecting member 212, the connecting member 212 is hinged to the fixed end of the pin driving component 213 through the hinge 216, the driving end of the pin driving component 213 is connected to the pin 215, the fixed end of the pin driving component 213 is connected to the needle plate 214, and the roller 217 is installed at the fixed end of the pin driving component 213.

[0039] The material taking device 2 of the present application can adapt to the change of the number of pieces when taking a large number of stacked pieces with uneven thickness through the proper coordination among the material moving mechanism 20, the material taking driving component 211, the connecting piece 212, the pin driving component 213, the needle plate 214, the pin 215, the hinge 216 and the roller 217, so as to realize the layered and stable material taking, avoid the material leakage, realize the full process automatic material taking, and improve the production efficiency. The material taking device 2 can rotate around the pin of the hinge 216 by adding the hinge 216 and the roller 217, and freely swing with the change of the height of the piece pile, and then the pin driving component 213 can drive the pin 215 to adapt to the change of the shape of the piece pile caused by the change of the number of pieces, so that the pin surface of the needle plate 214 is always parallel to the piece, ensuring that the pin surface has a large contact area with the piece, thereby avoiding the pin 215 from missing the piece, and realizing stable layered material taking. In addition, the material taking device 2 is compatible with a pile of cut pieces with uniform thickness, and can also achieve stable layered material taking for the pile of cut pieces with uniform thickness. In addition, adding rollers 217 to the material taking device 2 can also reduce the wear of the cut pieces and the material taking device 2 when the material taking device 2 contacts and moves with the cut pieces.

[0040] It can be understood that the material moving mechanism 20 is used to move the material picking mechanism 21; the material picking drive component 211 is used to control the longitudinal movement of the pin drive component 213; the pin drive component 213 can rotate freely around the hinge 216, and the pin drive component 213 can drive the pin 215 to insert the cut piece; the roller 217 can roll freely to reduce the wear of the material picking device 2 when it contacts and moves with the cut piece; the connecting piece 212 is used to connect the pin drive component 213 with the material picking drive component 211.

[0041] In some embodiments, the connecting member 212 is fixedly connected to one hinge of the hinge 216 , and the other hinge of the hinge 216 is fixedly connected to the fixed end of the pin driving component 213 .

[0042] In some embodiments, the material taking mechanism 21 further includes a limiting structure 218 for limiting the opening and closing angle of the hinge 216, one end of the limiting structure 218 is fixed to the connecting member 212, and the other end is limitedly matched with the pin driving component 213. The limiting structure can limit the maximum opening and closing angle of the hinge, thereby limiting the maximum rotation angle of the pin driving component under its own gravity, which is conducive to adjusting the rotation angle according to the shape of the cut piece pile, accurately taking the material, and further avoiding the phenomenon of material leakage or adhesion and entrainment of the cut pieces.

[0043] See also Figure 1 and Figure 7~Figure 10 In some embodiments, the limiting structure 218 includes a fixed plate 2181, an extension plate 2182, a screw hole plate 2183, a limiting screw 2184 and a limiting nut 2185. The screw hole plate 2183 is provided with a limiting screw hole 2186. The fixed plate 2181 is fixedly connected to the connecting member 212. The extension plate 2182 is fixedly connected to the fixed plate 2181. The screw hole plate 2183 is fixedly connected to the extension plate 2182. The limiting screw 2184 passes through the limiting screw hole 2186. The limiting end of the limiting screw 2184 is limitedly matched with the fixed end of the pin driving component 213. The limiting nut 2185 is fastened to the limiting screw 2184.

[0044] In some embodiments, the extension plate 2182 is perpendicular to the fixing plate 2181 and the screw hole plate 2183 , respectively. The fixing plate 2181 is located on the top side of the extension plate 2182 , and the screw hole plate 2183 is located on the bottom side of the extension plate 2182 .

[0045] See also Figure 7 and Figure 8 In some embodiments, the position of the limit screw limit end 2187 is adjusted to limit the position of the pin drive component 213. When the limit screw limit end 2187 abuts against the protruding plate 2131 on the pin drive component 213, the position of the limit screw limit end 2187 is the maximum angle of rotation and swing of the pin drive component 213; see Fig. 9 and Fig.10 When the limiting end 2187 of the limiting screw is away from the protruding plate 2131 on the pin driving component 213 and the limiting end 2187 of the limiting screw cannot abut against the protruding plate 2131, the pin driving component 213 is directly connected to the connecting member 212 through the hinge 216, and the hinge has a maximum angle of 90 degrees.

[0046] Understandably, see Figure 7 and Figure 8When it is necessary to take materials from a pile of pieces with uneven thickness, the maximum rotation angle of the pin drive component 213 under its own gravity is controlled by adjusting the position of the limit screw limit end 2187. The greater the fluctuation of the piece pile, the greater the required maximum rotation angle, which is adjusted according to actual conditions.

[0047] When it is necessary to take material from a pile of cut pieces with uniform thickness, the position of the limiting end 2187 of the limiting screw is adjusted so that the two hinges of the hinge 216 are fitted together. At this time, the pin driving component 213 cannot rotate around the hinge 216, and the pin driving component 213 no longer swings. The pin surfaces of the pin driving component 213 and the needle plate 214 thereon are in a horizontal state, and the pin surfaces are always parallel to the display table 31, which is equivalent to directly fixing the pin driving component 213 on the material taking drive component 211. At this time, it is suitable for taking material from a pile of cut pieces with uniform thickness, and the wear of the hinge 216 can be reduced.

[0048] In some embodiments, a return spring is connected between the connecting member 212 and the pin driving component 213. At this time, the pin driving component 213 swings around the hinge 216 and then returns to its original position through the spring.

[0049] In some embodiments, the material taking driving component 211 is a slide cylinder.

[0050] In some of these implementations, see Figure 11~Figure 15 The pin 215 is a row-type structure, and a plurality of material extraction needles are arranged at the bottom of the pin 215. The pin 215 is connected to the driving end of the pin driving component 213, and the needle plate 214 is connected to the fixed end of the pin driving component 213. The needle plate is provided with a plurality of pin limiting holes 2141. The driving end of the pin driving component 213 can drive the material extraction needle of the pin 215 to extend out from the pin limiting hole 2141 of the needle plate 214. The retracted state of the pin 215 is as shown in FIG. Fig.13 As shown, the pin 215 is extended as shown in Fig.14 shown.

[0051] In some of the embodiments, the material extraction needles on the insertion needles 215 may be perpendicular to the insertion needle surface of the needle plate 214 or at a certain inclined angle.

[0052] It is understood that the pin insertion surface of the needle plate 214 is the contact surface of the needle plate 214 that contacts the cut piece.

[0053] In some of the embodiments, a pin cylinder is used to replace the pin driving component 213, the pin plate 214 and the pin 215.

[0054] See also Figure 2 In some embodiments, the material picking mechanism 21 further includes a sensor 219 for sensing a position change of the material picking drive component 211 , and the sensor 219 is disposed on the material picking drive component 211 .

[0055] It can be understood that by detecting the upper and lower positions of the driving end of the material picking drive component 211 through the sensor 219, it is possible to detect whether the cut pieces are inserted in place. The continuous reduction in the number of adaptive cut pieces causes the height of the cut piece pile to change, so that the material picking device 2 can fully automatically complete the layered and stable material picking of stacked cut pieces with uneven thickness.

[0056] In some embodiments, the sensor 219 is a mechanical sensor such as a reed switch, a micro switch or a proximity switch. Avoid using a photoelectric sensor to prevent the floating lines and dust of the cut piece from affecting the sensor.

[0057] Furthermore, the sensor 219 adopts a reed switch, and the material picking drive component 211 adopts a slide cylinder. The sensor 219 is installed on the fixed slide of the slide cylinder. A magnetic ring is provided on the movable slide of the slide cylinder. The reed switch can detect the position of the magnetic ring. When the cut piece moves upward into place, it will push the movable slide of the slide cylinder. The reed switch indirectly detects whether the cut piece is in place by detecting the magnetic ring on the movable slide of the slide cylinder.

[0058] See also Figure 3 In some embodiments, the material moving mechanism 20 includes a frame, a material moving drive component 200, a movable connecting block 201 and a material picking fixing member 202. The material moving drive component 200 is fixed on the frame, the driving end of the material moving drive component 200 is connected to the movable connecting block 201, the movable connecting block 201 is connected to the material picking fixing member 202, and the material picking fixing member 202 is connected to the fixed end of the material picking drive component 211.

[0059] It can be understood that the material taking fixture 202 is used to connect the material taking driving component 211 .

[0060] In some of the embodiments, the material moving drive component 200 and the movable connecting block 201 adopt a rodless cylinder, and the movable connecting block 201 is a movable slider on the rodless cylinder. The movable connecting block 201 is connected to the material picking fixing piece 202. The external movable connecting block 201 is driven by the magnet inside the rodless cylinder body, and then the material picking mechanism 21 is driven to move back and forth to realize material picking and removing.

[0061] In some of the embodiments, the material moving mechanism 20 adopts a structure in which a robot, a linear module or a cylinder is matched with a guide rail.

[0062] In some embodiments, the material taking device 2 includes a plurality of material taking mechanisms 21. When the cut pieces are small, only one material taking mechanism 21 may be provided; when the cut pieces are large, in order to maintain the material taking balance, a plurality of material taking mechanisms 21 may be provided, and the distance between the material taking mechanisms 21 may be adjusted to accommodate cut pieces of different lengths.

[0063] See also Figure 5In some of the embodiments, a spacing adjustment structure 2021 for adjusting the spacing between the plurality of material taking driving components 211 is provided on the material taking fixing member 202 .

[0064] Furthermore, the spacing adjustment structure 2021 may be a slideway for installing the material taking driving component 211 .

[0065] It can be understood that the spacing adjustment structure 2021 can adjust the spacing between the multiple material-taking driving components 211, and further adjust the spacing between the multiple pin driving components 213.

[0066] See also Figure 16~Figure 20 The second aspect of the present application provides a material picking device, including a piece conveying device 1, a piece placing device 3 and the material picking device 2 of the first aspect mentioned above, the piece conveying device 1 is located upstream of the material picking device 2, and the piece placing device 3 is located downstream of the material picking device 2.

[0067] It can be understood that upstream and downstream refer to the upstream process and downstream process in the flow sequence of the cut pieces.

[0068] See also Fig.17 In some embodiments, the cut piece placement device 3 includes a placement table 31, on which a cut piece positioning structure 32 is provided, and a positioning surface of the cut piece positioning structure 32 forms an angle of 30 to 75 degrees with the surface of the placement table 31. The cut piece positioning structure 32 is used to position the cut pieces so that the cut pieces are neatly placed; when the positioning surface of the cut piece positioning structure 32 forms an angle of 30 to 75 degrees with the surface of the placement table 31, an excellent cut piece positioning effect is obtained.

[0069] In some embodiments, the cut piece positioning structure 32 may be a baffle installed on the edge of the display table 31 .

[0070] See also Fig.18 In some embodiments, a plurality of blowing holes 311 are provided on the placing table 31. The placing table 31 is fixed on the frame and is used to place the cut pieces after the material is taken. The blowing holes 311 thereon are used to install a blowing nozzle to arrange the cut pieces. A conical blowing nozzle can be installed on the blowing hole 311, and at the same time, a protrusion is avoided on the placing table 31.

[0071] See also Fig.21 In some embodiments, the cut piece conveying device 1 includes a support table 12 and a support table driving component 11, and a driving end of the support table driving component 11 is connected to the support table 12. The support table driving component 11 can drive the support table 12 to move longitudinally.

[0072] In some embodiments, the support platform driving component 11 is a linear module driven by a motor.

[0073] See also Fig.21In some embodiments, a buffer layer 121 is provided on the support platform 12. The buffer layer 121 is installed on the support platform and is used to place the cut pieces to prevent the pins 215 from being damaged or worn.

[0074] Furthermore, the buffer layer 121 is a sponge layer.

[0075] The working process of the above-mentioned reclaiming equipment is as follows:

[0076] like Fig.21 As shown, a piece pile 4 formed by stacking pieces of uneven thickness is placed on the buffer layer 121 of the support table 12 of the piece conveying device 1; the material moving driving component 200 drives the moving connecting block 201 to extend, and at the same time, the driving end of the material taking driving component 211 also extends, and the support table driving component 11 of the piece conveying device 1 drives the support table 12 to move upward, and the piece pile 4 is placed on the buffer layer 121 of the support table 12. When the support table 12 rises, the top of the piece pile 4 first touches the roller 217 of the material taking device 2, and the piece pile 4 pushes the roller 217 to rise, and at the same time, the roller 2 17 moves relatively along the top surface of the piece pile. At this time, the piece pile 4 pushes the pin drive component 213 to rotate around the hinge 216, so that the pin surface of the needle plate 214 can be parallel to the top surface of the piece pile 4, obtaining a larger contact area. When the contact area between the pin surface and the piece is the largest, the effect of the piece pile 4 on the pin drive component 213 is no longer to rotate around the hinge 216, but to push the pin drive component 213 to move upward with the driving end of the material-taking driving component 211. When the sensor 219 senses the position change of the driving end of the material-taking driving component 211, as shown in FIG. Fig.14 As shown, the driving end of the pin driving component 213 extends out to drive the pin 215 to insert a single-layer piece, and the support table driving component 11 drives the remaining piece pile to move downward a certain distance as a whole through the support table 12. The material moving mechanism 20 moves the material picking mechanism 21 to move the inserted piece to the placing table 31 of the piece placing device 3; the pieces are continuously grabbed, and the shape of the piece pile is continuously flattened. The material picking mechanism 21 can adaptively grab the pieces under the action of the hinge 216, thereby realizing automatic grabbing of the pieces in the whole process.

[0077] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
