Abstract
Description
Technical Field
[0001] The present application relates to the field of ink production equipment, and in particular to a turntable assembly and a color mixing machine. Background Art
[0002] The basic principle of various car paints, oil paints, latex paints or inks is to mix various masterbatches and auxiliary materials according to the formula to finally obtain the required coating. In addition to the most traditional manual mixing by paint mixes, there are also increasingly popular paint mixing equipment of various shapes. The paint mixing equipment generally includes multiple masterbatch barrels and a batching and conveying module. The batching and conveying module discharges the masterbatches in different masterbatch barrels according to the formula and mixes them in related containers to obtain the required coating.
[0003] Nowadays, there are more and more customers who customize various coatings in the market. Meeting this demand means that the color mixing equipment must be able to store various masterbatch barrels in a constant environment to ensure that the masterbatch will not deteriorate due to repeated contact with the air. In addition, large-capacity masterbatch raw material storage tanks are not conducive to application in this demand scenario. After the large-capacity masterbatch raw material storage tanks pour the masterbatch into the small-capacity masterbatch barrels many times, the quality of the masterbatch may be affected, and the masterbatch may also hang on the wall and solidify and be lost. One type of color matching equipment on the market includes a rectangular masterbatch barrel storage cabinet, in which a plurality of masterbatch barrels are arranged in a matrix distribution on a plane. A discharging actuator for quantitatively dispensing masterbatches in the masterbatch barrels is arranged on one side of the masterbatch barrel storage cabinet. In order to deliver the masterbatch barrels to the discharging actuator, a set of robot parts is also required in the masterbatch barrel storage cabinet. The robot parts need to have a motion mechanism in three axes of XYZ, and the motion track lengths of the X-axis and Y-axis may increase as the number of masterbatch barrels increases, resulting in the masterbatch barrels running for a long time in the masterbatch barrel storage cabinet. In addition, due to the matrix distribution of the masterbatch barrels, the robot parts need to move different distances to pick up and place masterbatch barrels in different positions, and the motion mode of the robot parts is relatively complex, making the structure of the color matching machine relatively complex. Utility Model Content
[0004] The purpose of the present application is to provide a turntable assembly and a color mixing machine, so as to make the structure of the color mixing machine more streamlined.
[0005] The embodiment of the present application is implemented as follows:
[0006] In a first aspect, an embodiment of the present application provides a turntable assembly, comprising a workbench and a turntable rotatably connected to the workbench, wherein the upper surface of the turntable has a plurality of masterbatch barrel mounting positions distributed along a circumference, and the axis of rotation of the turntable passes through the center of the circle.
[0007] A number of limiting members corresponding to the masterbatch barrel mounting positions are distributed along the circumference, and the limiting members are spaced apart from the masterbatch barrel mounting positions; the limiting members have an arcuate surface extending along the axial direction, and the arcuate surface is used to limit the masterbatch barrel assembly from moving toward the center of the circle along the radial direction of the circumference.
[0008] In the above technical scheme, the masterbatch barrel installation position is used to place the masterbatch barrel assembly. Since the masterbatch barrel installation positions are distributed on the turntable in the circumferential direction, the masterbatch barrel installation positions will pass through the same position during the rotation of the turntable. Therefore, when the turntable assembly provided by the above technical scheme is applied to the color mixing machine, the turntable can be rotated and the masterbatch barrel grasping mechanism such as the manipulator component can be used to pick up and place the masterbatch barrel assembly at the position that each masterbatch barrel installation position will pass through, thereby achieving that when taking and placing each masterbatch barrel assembly, the movement distance of the masterbatch barrel grasping mechanism is the same, which can make the structure of the masterbatch barrel grasping mechanism simpler, and thus make the structure of the color mixing machine using the turntable assembly provided by the above technical scheme more streamlined.
[0009] In addition, since a limiter corresponding to the number of masterbatch barrel installation positions is provided, the masterbatch barrel assembly is limited to move toward the center of the circle along the radial direction of the circumference by the arc surface of the limiter, and the masterbatch barrel assembly can be positioned when the masterbatch barrel grasping mechanism places the masterbatch barrel assembly in the masterbatch barrel installation position, thereby improving the position accuracy of the masterbatch barrel assembly and further improving the accuracy in the process of taking and placing the masterbatch barrel assembly. Furthermore, the arc surface extends along the direction of the rotation axis of the turntable and can play a role in limiting the movement of the masterbatch barrel assembly toward the center of the circle. Therefore, the arc surface has a certain size in the extension direction of the rotation axis, and the contact surface with the masterbatch barrel assembly is large, which can reduce the damage to the masterbatch barrel assembly to a certain extent.
[0010] In combination with the first aspect, in some optional embodiments, the limiting member includes a first arc-shaped plate and a second arc-shaped plate connected to each other, and the first arc-shaped plate and the second arc-shaped plate both have the arc-shaped surface.
[0011] One of the two adjacent limiting members is noted as the first limiting member, and the other is noted as the second limiting member; and the masterbatch barrel installation position located between the first limiting member and the second limiting member is noted as the first masterbatch barrel installation position.
[0012] The arc surface of the first arc plate located in the first limiting member and the arc surface of the second arc plate located in the second limiting member jointly restrict the masterbatch barrel assembly disposed at the first masterbatch barrel installation position from moving toward the center of the circle along the radial direction of the circumference.
[0013] In the above technical solution, the first arc plate in the first limiting member and the second arc plate in the second limiting member are used to jointly limit the movement of the masterbatch barrel assembly toward the center of the circle at the masterbatch barrel installation position, which can reduce the processing difficulty of the limiting member.
[0014] In combination with the first aspect, in some optional embodiments, the arcuate surface is a circular surface, and the installation positions of the first limit member and the second limit member are configured so that the arcuate surface of the first arc plate located in the first limit member and the arcuate surface of the second arc plate located in the second limit member are located on the same cylindrical surface.
[0015] In the above technical solution, since the arc surfaces in the limiting members are all circular surfaces, and the arc surface of the first arc plate in the first limiting member and the arc surface of the second arc plate in the second limiting member are on the same cylindrical surface, the first limiting member and the second limiting member can jointly play a role in limiting the masterbatch barrel assembly.
[0016] In combination with the first aspect, in some optional embodiments, the limiting member also includes a positioning block, the positioning block is connected to the turntable, and the first arc plate and the second arc plate are connected to the positioning block; the positioning block extends along the radial direction of the circumference; the positioning block in the first limiting member and the positioning block in the second limiting member jointly limit the movement of the masterbatch barrel assembly located at the first masterbatch barrel installation position in the circumferential direction.
[0017] In the above technical solution, the positioning block in the limit member extends along the radial direction of the circumference. During the rotation of the turntable, the first limit member and the second limit member jointly limit the movement of the masterbatch barrel assembly in the circumferential direction through the positioning block, which can reduce the position change of the masterbatch barrel assembly, so that the masterbatch barrel grasping mechanism can more accurately pick up the masterbatch barrel assembly in the masterbatch installation position, thereby improving the accuracy of the process of picking up the masterbatch barrel assembly.
[0018] In combination with the first aspect, in some optional embodiments, the limiting member also includes a side plate, and the first arc plate and the second arc plate are both connected to one side edge of the side plate to form a structure with a Y-shaped cross-section; the other side edge of the side plate is connected to the positioning block.
[0019] In the above technical solution, the first curved plate, the second curved plate and the positioning block are connected by side plates, and the side plates can act as reinforcing ribs between the first curved plate, the second curved plate and the positioning block, thereby reducing the large deformation of the first curved plate and the second curved plate that may be caused in the process of positioning the masterbatch barrel assembly by the first curved plate and the second curved plate, thereby improving the positioning accuracy of the first curved plate and the second curved plate for the masterbatch barrel assembly, thereby improving the accuracy in the process of taking and placing the masterbatch barrel assembly.
[0020] In combination with the first aspect, in some optional embodiments, in a direction away from the first arc-shaped plate, a dimension of the side plate in a direction extending along the axis gradually decreases.
[0021] In the above technical solution, the space occupied by the side panel is relatively small, which can reduce the space occupied by the turntable assembly and reduce the possibility of interference between the side panel and other structures.
[0022] In combination with the first aspect, in some optional embodiments, the size of the arc surface in the axial direction is not less than 10 cm. In the above technical solution, the size of the arc surface in the axial direction is larger, and the contact surface with the masterbatch barrel assembly is larger, which can reduce the damage to the masterbatch barrel assembly to a certain extent and improve the positioning effect of the masterbatch barrel assembly.
[0023] In combination with the first aspect, in some optional embodiments, the workbench is also connected to a guard plate, which is an arc-shaped structure and surrounds the outside of the masterbatch barrel installation position, and the top of the guard plate is higher than the upper surface of the turntable.
[0024] In the above technical solution, the guard plate surrounds the outside of the masterbatch barrel installation position, and the top of the guard plate is higher than the upper surface of the turntable. Therefore, the guard plate can limit the movement of the masterbatch barrel assembly installed on the upper surface of the turntable away from the center of the circle in the radial direction of the circumference, thereby reducing the position change of the masterbatch barrel assembly, so that the masterbatch barrel grasping mechanism can more accurately pick up the masterbatch barrel assembly in the masterbatch barrel installation position, thereby improving the accuracy of the process of picking up the masterbatch barrel assembly.
[0025] In combination with the first aspect, in some optional embodiments, the guard plate forms an annular structure having a gap, and the gap is configured to allow the masterbatch barrel assembly to pass through.
[0026] In the above technical solution, the masterbatch barrel assembly can be taken and placed through the notch of the annular structure, thereby simplifying the movement mode of the masterbatch barrel grabbing mechanism, making the structure of the color mixing machine using the above turntable assembly more streamlined.
[0027] In a second aspect, an embodiment of the present application provides a color mixing machine, comprising a masterbatch barrel assembly, a masterbatch barrel grabbing mechanism, a driving device, and a turntable assembly provided in the first aspect; the driving device is installed on the workbench and is transmission-connected to the turntable, and the masterbatch barrel assembly is arranged at the masterbatch barrel mounting position; the color mixing machine is configured such that the masterbatch barrel grabbing mechanism can enter the gap and take the masterbatch barrel assembly out of the gap.
[0028] In the color mixing machine provided by the above technical solution, the masterbatch barrel assembly is taken and placed through the notch of the guard plate under the action of the masterbatch barrel grabbing mechanism. The preset masterbatch barrel installation position can be rotated to a designated position close to the masterbatch barrel grabbing mechanism through the turntable, so that the masterbatch barrel grabbing mechanism can take the masterbatch barrel assembly from the preset masterbatch barrel installation position through the notch, or place the masterbatch barrel assembly in the preset masterbatch barrel installation position. This method can be used to take and place the masterbatch barrel assembly for masterbatch barrel installation positions in different positions, so as to simplify the movement mode of the masterbatch barrel grabbing mechanism and make the structure of the color mixing machine more streamlined. Since the turntable assembly is also provided with a limiting member for limiting the masterbatch barrel assembly, the masterbatch barrel assembly can be positioned and the position change of the masterbatch barrel assembly on the turntable can be reduced, so that the masterbatch barrel grabbing mechanism can take and place the masterbatch barrel assembly more accurately, thereby improving the accuracy in the process of taking and placing the masterbatch barrel.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0042] The present application provides a color mixing machine, which can simplify the movement mode of the masterbatch barrel grabbing mechanism so that the color mixing machine has a more streamlined structure.
[0043] like Figures 1 to 3 As shown, the color mixing machine provided by the present application includes a masterbatch barrel assembly 300, a masterbatch barrel grabbing mechanism, a turntable assembly 200, and a driving device 500. The turntable assembly 200 also includes a workbench 210 and a turntable 220 rotatably connected to the workbench 210. The workbench 210 is fixedly arranged, for example, the workbench 210 is connected to the frame 100 of the color mixing machine, and during the operation of the color mixing machine, the workbench 210 is stationary relative to the ground. The turntable 220 is transmission-connected to the driving device 500, and then the turntable 220 is driven to rotate by the driving device 500. The turntable 220 has a plurality of masterbatch barrel mounting positions 221 distributed along the circumference, and the masterbatch barrel assembly 300 is placed on the masterbatch barrel mounting position 221. The plurality of masterbatch barrel mounting positions 221 are distributed along the circumference on the upper side of the turntable 220, and the center of the circumference is located on the axis of rotation of the turntable 220. Figures 1 to 5 In the embodiment, the turntable 220 is a disc-shaped structural member, and the rotation axis of the turntable 220 is perpendicular to the upper surface of the turntable 220. During the rotation of the turntable 220, the motion trajectory of each masterbatch barrel installation position 221 is the same, and accordingly, the motion trajectory of each masterbatch barrel assembly 300 is also the same, so that the preset masterbatch barrel installation position 221 can be rotated to a position close to the masterbatch barrel grasping mechanism to take or place the masterbatch barrel assembly 300. It is not difficult to understand that the preset masterbatch barrel installation position 221 is selected by the operator or the control program according to the setting position of the required masterbatch barrel assembly 300 before the masterbatch barrel grasping mechanism takes it, or is selected according to the position of the idle masterbatch barrel placement position.
[0044] In the above-mentioned color mixing machine provided by the present application, since the motion trajectory of each masterbatch barrel installation position 221 is the same and the motion trajectory of each masterbatch barrel assembly 300 is the same, when taking and placing the masterbatch barrel assembly 300 for each masterbatch barrel installation position 221, the driving device 500 can be used to drive the turntable assembly 200 to rotate, so that the preset masterbatch barrel installation position 221 rotates to a position close to the masterbatch barrel grabbing mechanism, and then the masterbatch barrel grabbing mechanism takes the masterbatch barrel assembly 300 from the preset masterbatch barrel installation position 221, or places the masterbatch barrel assembly 300 to the preset masterbatch barrel installation position 221. Therefore, the motion mode of the masterbatch barrel grabbing mechanism is independent of the placement position of the masterbatch barrel assembly 300, which simplifies the motion mode of the masterbatch barrel grabbing mechanism, thereby making the structure of the color mixing machine more streamlined.
[0045] In some embodiments, the rotating disk 220 and the driving device 500 are connected to each other through a gear mechanism. Figure 3In the illustrated embodiment, a gear ring is provided on the lower side of the turntable 220, and the driving device 500 is a motor installed on the workbench 210. The output shaft of the motor is connected to a gear meshed with the gear ring, and the turntable 220 is driven to rotate by the rotation of the motor. Further, the masterbatch barrel installation position 221 is located on the upper side of the turntable 220, that is, the masterbatch barrel assembly 300 is placed on the upper side of the turntable 220.
[0046] Further, in order to achieve higher precision in the process of taking and placing the masterbatch barrel assembly 300, in some embodiments of the present application, there are also distributed along the circumference of the masterbatch barrel installation positions 221 a corresponding number of limiters 230 of the masterbatch barrel installation positions 221. The masterbatch barrel installation positions 221 and the limiters 230 are arranged at intervals, that is, on the circumference of the masterbatch barrel installation positions 221, there is a limiter 230 between two adjacent masterbatch barrel installation positions 221, and there is a masterbatch barrel installation position 221 between two adjacent limiters 230. The limiting member 230 has an arcuate surface 231 extending along the direction of the rotation axis of the turntable 220, and the arcuate surface 231 limits the movement of the masterbatch barrel assembly 300 toward the center of the circle along the radial direction of the circumference. Therefore, when the masterbatch barrel grasping mechanism places the masterbatch barrel assembly 300 in the masterbatch barrel installation position 221, the masterbatch barrel assembly 300 can be positioned, thereby improving the accuracy of the process of placing the masterbatch barrel assembly 300, ensuring the position accuracy of the masterbatch barrel assembly 300 in the masterbatch barrel installation position 221, and on this basis, also improving the accuracy of the process of taking the masterbatch barrel assembly 300 from the masterbatch barrel installation position 221.
[0047] exist Figure 4 In the embodiment shown, the rotation axis of the turntable 220 extends in the vertical direction, and accordingly, the arc surface 231 extends in the vertical direction, that is, the curve formed by the intersection of the arc surface 231 and the horizontal plane is an arc, and the curve formed by the intersection of the arc surface 231 and the vertical plane is a straight line. It should be easy to understand for those skilled in the art that, since the arc surface 231 can position the masterbatch barrel assembly 300 when the masterbatch barrel grasping mechanism places the masterbatch barrel assembly 300 in the masterbatch barrel installation position 221, the arc surface 231 has a certain size in the direction of the rotation axis of the turntable 220. Therefore, as shown in FIG. Figure 2 and Figure 3 As shown, the contact surface between the arc surface 231 and the masterbatch barrel assembly 300 is relatively large, which can reduce the damage to the masterbatch barrel assembly 300 to a certain extent. Further, the size of the arc surface 231 in the direction of the rotation axis of the turntable 220 is not less than 10 cm, and further, it can be 10 cm to 20 cm, such as 10 cm, 12 cm, 14 cm, 16 cm, 18 cm and 20 cm. In other embodiments, it can also be 25 cm, 30 cm, etc.
[0048] In some embodiments of the present application, the structure of the stopper 230 is as follows: Figure 2 , Figure 4 and Figure 5 As shown, it includes a first curved plate 232 and a second curved plate 233 connected to each other, and the first curved plate 232 and the second curved plate 233 both have a curved surface 231 for limiting the movement of the masterbatch barrel assembly 300 along the radial direction of the circumference toward the center of the circle. Further, one of the two adjacent limiting members 230 is recorded as the first limiting member and the other is recorded as the second limiting member; the masterbatch barrel installation position 221 located between the first limiting member and the second limiting member is recorded as the first masterbatch barrel installation position. The curved surface 231 of the first curved plate 232 located in the first limiting member and the curved surface 231 of the second curved plate 233 located in the second limiting member jointly limit the masterbatch barrel assembly 300 disposed at the first masterbatch barrel installation position from moving along the radial direction of the circumference toward the center of the circle. In this embodiment, the method of using two adjacent limiting members 230 to jointly limit the movement of the masterbatch barrel assembly 300 located between the two adjacent limiting members 230 can reduce the processing difficulty of the limiting member 230.
[0049] Furthermore, the arc surface 231 is a circular surface, that is, the curve formed by the intersection of the arc surface 231 and the horizontal plane is an arc. Figure 5 As shown, after the first limiting member and the second limiting member are connected to the rotating disk 220 , the arc surface 231 of the first arc plate 232 and the arc surface 231 of the second arc plate 233 are located on the same cylindrical surface.
[0050] In the above implementation mode, if Figure 5 As shown, in the stopper 230, the first curved plate 232 and the second curved plate 233 form a substantially V-shaped structure. In some other embodiments, the curved surface 231 of the first curved plate 232 and the curved surface 231 of the second curved plate 233 in the stopper 230 may be smoothly connected to form a continuous curved surface, that is, the first curved plate 232 and the second curved plate 233 in the same stopper 230 form a substantially ∩-shaped structure.
[0051] Further, in some embodiments, the limiting member 230 further includes a positioning block 234 for limiting the movement of the masterbatch barrel assembly 300 in the radial direction. Figure 2 and Figure 5As shown, the positioning block 234 is connected to the rotating disk 220, and the first arc plate 232 and the second arc plate 233 are both connected to the positioning block 234. The positioning block 234 is arranged in a manner of extending along the radial direction of the center of the distribution circle of the masterbatch barrel installation position 221, and the positioning blocks 234 in the first limiting member and the second limiting member respectively limit the movement of the masterbatch barrel assembly 300 in the circumferential direction from both sides in the circumferential direction. By limiting the movement of the masterbatch barrel assembly 300 in the circumferential direction, the masterbatch barrel grasping mechanism can more accurately pick up the masterbatch barrel assembly 300 in the masterbatch barrel installation position 221, thereby improving the accuracy of the process of picking up the masterbatch barrel assembly 300.
[0052] Furthermore, in some embodiments, the stopper 230 further includes a side plate 235 connecting the arc plate (including the first arc plate 232 and the second arc plate 233) and the positioning block 234, that is, the first arc plate 232 and the second arc plate 233 are both directly connected to the positioning block 234 and indirectly connected to the positioning block 234 through the side plate 235, so as to increase the rigidity of the overall structure of the stopper 230 and reduce the deformation of the stopper 230 under the action of external force. Figure 4 and Figure 5 As shown, the first curved plate 232 and the second curved plate 233 are both connected to one side edge of the side plate 235, and the first curved plate 232, the second curved plate 233 and the side plate 235 form a structure with a Y-shaped cross section. It is not difficult to understand that the cross section is a cross section perpendicular to the extension direction of the curved surface 231. The edge of the other adjacent side of the side plate 235 is connected to the positioning block 234. Figure 4 and Figure 5 In the structure shown, the side plate 235 can act as a reinforcing rib. In the process of placing the masterbatch barrel assembly 300 into the masterbatch barrel installation position 221 through the masterbatch barrel grabbing mechanism, the first curved plate 232 and the second curved plate 233 may come into contact with the masterbatch barrel assembly 300. Therefore, due to the presence of the side plate 235, the deformation amount occurring at one end of the first curved plate 232 and the second curved plate 233 away from the positioning block 234 can be reduced.
[0053] Furthermore, in order to reduce the possibility of interference between the side plate 235 and other structures (such as the masterbatch barrel grasping mechanism), the size of the side plate 235 in the extending direction of the axis of the rotating disk 220 (that is, the extending direction of the arc surface 231) gradually decreases in the direction away from the first arc plate 232. Figure 2 As shown, the side plate 235 is a triangular structure.
[0054] exist Figures 2 to 5In the embodiment shown, the turntable assembly 200 further includes a guard plate 240 connected to the workbench 210. The guard plate 240 is an arc-shaped structure and surrounds the outer side of the masterbatch barrel installation position 221. The top of the guard plate 240 is higher than the upper surface of the turntable 220. Further, the connection position between the guard plate 240 and the workbench 210 is located on the outer side of the turntable 220, and the surface of the guard plate 240 for limiting the movement of the masterbatch barrel assembly 300 is located on the inner side of the edge of the turntable 220. Figure 3 In the illustrated embodiment, the guard plate 240 has a vertically arranged circumferential surface, the axis of which coincides with the rotation axis of the turntable 220 , and the radius of which is larger than the radius of the circle where the masterbatch barrel mounting position 221 is located and smaller than the radius of the turntable 220 .
[0055] It is not difficult to understand that the guard plate 240 can limit the masterbatch barrel assembly 300 from moving away from the center of the circle in the radial direction of the circumference under the action of centrifugal force, thereby reducing the position change of the masterbatch barrel assembly 300, so that the masterbatch barrel grasping mechanism can more accurately pick up the masterbatch barrel assembly 300 at the masterbatch barrel installation position 221, thereby improving the accuracy of the process of picking up the masterbatch barrel assembly 300.
[0056] Further, if Figure 3 In the illustrated embodiment, the guard plate 240 is surrounded by an annular structure having a notch 241, and the size of the notch 241 allows the masterbatch barrel assembly 300 to pass through. It should be easy for a person skilled in the art to understand that in the process of the masterbatch barrel grasping mechanism taking and placing the masterbatch barrel assembly 300, the masterbatch barrel assembly 300 can pass through the notch 241, so there is no need to make the movement mode of the masterbatch barrel grasping mechanism more complicated in order to avoid the guard plate 240, so that the movement mode of the masterbatch barrel grasping structure is relatively simple. It is easy to understand that the size of the notch 241 should also meet the requirements that the masterbatch barrel grasping structure can pass through to take and place the masterbatch barrel assembly 300 at the masterbatch barrel installation position 221.
[0057] exist Figures 2 to 5 In the illustrated embodiment, the guard plate 240 is a longer annular structure having a notch 241 and surrounded by a plurality of shorter arc-shaped structures to facilitate the processing of the guard plate 240 ; in other embodiments, the guard plate 240 may also be an integral annular structure having a notch 241 .
