Description

TECHNICAL FIELD

[0001] The application relates to the technical field of football manufacturing equipment, in particular to a dispensing machine capable of automatically dispensing glue on a football. BACKGROUND

[0002] At present, the increasing popularity of football sports leads to an increasing demand for footballs. However, the current football products are manually dispensed with glue by workers, which is low in efficiency and high in labor cost, and the economic benefit is not high.

[0003] When the football product needs to be manually dispensed with glue, one hand is used to rotate the football, and the other hand is used to hold a glue cylinder to apply the raw glue to the joint of the football surface. Such operation not only needs to consume a large amount of manpower, but also causes uneven dispensing, uneven dispensing amount, repeated dispensing and other quality problems due to the motion coordination, concentration and fatigue of the dispensing workers. SUMMARY

[0004] To solve the problems of low efficiency and unstable quality of manual football dispensing, the application provides an automatic dispensing machine for football.

[0005] The football dispensing machine with a rotating clamping structure provided by the application adopts the following technical scheme:

[0006] The automatic dispensing machine for football includes a positioning mechanism, a rotating clamping mechanism, a rotating mechanism, a dispensing mechanism and a control system. The positioning mechanism is used to position the football at a designated processing point. The rotating clamping mechanism includes a clamping mechanism and a rotating mechanism. The clamping mechanism and the rotating mechanism jointly clamp the football at the designated processing point. The rotating mechanism is used to rotate the football in the front-back direction. The rotating mechanism is used to rotate the rotating clamping mechanism, thereby driving the football rotating in the front-back direction to rotate in the left-right direction. The dispensing mechanism is used to dispense glue on the joint of the football surface in the rotating process. The upper vertex is the dispensing processing point. The control system can control the above-mentioned mechanisms. Before processing, the positioning mechanism is controlled to position the football at the designated processing point, and the dispensing mechanism is controlled to be located at the dispensing processing point. During processing, the rotating clamping mechanism and the rotating mechanism are controlled to make all joints of the football pass through the dispensing processing point during the processing process. The dispensing mechanism is controlled to dispense glue when the undispensed joint is located at the dispensing processing point, and the dispensing operation is stopped when the dispensed joint or non-joint surface passes through the dispensing processing point.

[0007] By adopting the technical scheme, the positioning mechanism can move the football to the specified processing point so that the rotating clamping mechanism can accurately clamp the football, which can avoid the situation that the football position deviates from the specified processing point during manual installation, leading to inaccurate dispensing or increasing the calculation and operation burden of the control system, and can also avoid the situation that the rotating clamping structure is clamped on the joint of the football, leading to the situation that part of the joint cannot be dispensed; the rotating clamping mechanism comprises a clamping mechanism and a rotating mechanism, the clamping mechanism stably and firmly clamps the football, which is beneficial to enhance the control of the football, so that the football can be rotated by the dispensing machine according to the specified order, direction and speed, and it is ensured that the football and the clamping mechanism do not slide relatively during the processing process, so as to ensure that the football processing is completed smoothly, in addition, the clamping mechanism stably and firmly clamps the football without excessive clamping to cause the football to deform, so as to affect the accuracy of processing; the rotating mechanism can make the football rotate in one direction, the rotating mechanism can make the rotating clamping mechanism rotate in a direction perpendicular to the rotating direction of the rotating mechanism, so as to drive the football to rotate in the direction, the cooperation of the rotating clamping mechanism and the rotating mechanism makes the football rotate in two perpendicular directions at the same time, so that the whole surface of the football can pass through the dispensing processing point located at the top point of the football, except the surface in contact with the clamping mechanism, but since the surface in contact with the clamping mechanism does not include the joint, this part of the surface does not need to pass through the dispensing processing point; the dispensing mechanism is used for dispensing operation at the dispensing processing point, since the rotating clamping structure and the rotating structure can make all the joints of the football surface pass through the dispensing processing point, therefore, the dispensing mechanism only needs to move to the dispensing processing point without moving again, which avoids the complex operation of moving the dispensing mechanism during the processing process, so that the design of the dispensing machine is more simple and clear, and the division of labor of each mechanism is clear, which is also beneficial to the control of the dispensing machine by the control system.The control system can be used to control the above-mentioned mechanism. Before the processing starts, the control system controls the football to be located at the specified processing point and controls the dispensing mechanism to be located at the dispensing processing point at the top of the football at the specified processing point, so as to ensure that the football and the dispensing mechanism are in a ready state for mutual cooperation before the processing starts. After the football is clamped by the rotating clamping mechanism, the control system controls the positioning mechanism to contact the football, so that the rotating clamping mechanism completely controls the football. After the processing starts, the control system controls the dispensing mechanism to start the dispensing operation, and simultaneously controls the rotating mechanism and the rotating mechanism to rotate. By controlling the rotating speed of the rotating mechanism and the rotating speed of the rotating mechanism according to the different directions of the seams, the football surface seams are driven by the above-mentioned two speeds to pass through the dispensing processing point at a uniform speed, so that the raw material glue applied by the dispensing mechanism can be uniformly distributed on the football surface seams. On the premise of uniform dispensing, the control of the dispensing rate of the dispensing mechanism is avoided, so that the operation difficulty of the control system is simplified. The football surface seams will pass through the dispensing processing point, so that the football surface seams can be dispensed, and processing defects can be avoided. In addition, if the dispensing mechanism inevitably needs to pass through the non-seam area or the dispensed area on the football surface during the processing, the control system needs to control the dispensing mechanism to stop the dispensing operation, and then start the dispensing operation when the seam needing to be dispensed is rotated to the dispensing processing point, so as to avoid repeated dispensing or dispensing at the non-seam. The raw material glue is saved, and the dispensing quality of the football is ensured. In summary, the control system can accurately, uniformly and repeatedly dispense the football surface seams, and the non-seam is not dispensed, so as to ensure the excellent and stable quality of the football product.

[0008] Optionally, the control system comprises a storage unit, a calculation unit and a control unit. The storage unit is used to store the specified processing point position information, the dispensing processing point position information, the football surface seam route information, the raw material glue amount information required by the unit seam length, and the dispensing speed information of the dispensing mechanism. The calculation unit can calculate the football rotating path which makes the football surface seams pass through the dispensing processing point according to the football surface seam route information stored in the storage unit, and then calculate the rotating angle and speed of the rotating clamping mechanism and the rotating mechanism and the dispensing operation start and stop time of the dispensing mechanism according to the calculated football rotating path, the raw material glue amount information required by the unit seam length and the dispensing operation speed information. The control unit can control the positioning mechanism to locate the football at the specified processing point according to the information of the storage unit, control the dispensing mechanism to be located at the dispensing processing point, control the rotating angle and speed of the rotating clamping mechanism and the rotating mechanism according to the rotating information of the rotating clamping mechanism and the rotating mechanism calculated by the calculation unit, and control the dispensing mechanism to start and stop the dispensing operation according to the time information of the dispensing operation start and stop time of the dispensing mechanism calculated by the calculation unit, so that the football surface seams can be accurately, uniformly and repeatedly dispensed.

[0009] By adopting the technical scheme, since the size of the processed football product, the joint line and the required raw material glue amount of the joint are equal, only the information needs to be stored in the storage unit of the control system, so that the input data before each processing and the matching checking process can be omitted, the processing process is accelerated, and the processing efficiency is improved. However, the information cannot be directly used by the dispensing machine, so the calculation unit needs to convert the joint line information on the surface of the football into the rotation path of the football according to the existing information, and then convert the rotation path of the football combined with the required raw material glue amount of the unit joint length and the dispensing speed of the dispensing mechanism into the rotation information of the rotary clamping mechanism and the rotation mechanism. The rotation information includes rotation speed information and time information for maintaining the rotation speed. The time information is determined by the length of the joint, the required raw material glue amount of the unit joint length and the dispensing speed of the dispensing mechanism. The rotation speed information is determined by the time information, the length of the joint and the direction. The rotation speed information of the rotary mechanism and the rotation mechanism is different, and the time information is the same. The two work together to make the joint pass through the dispensing processing point at a constant speed. Since the rotation path of the football inevitably passes through the non-joint surface or the joint that has been dispensed, the dispensing mechanism needs to be calculated according to the rotation path of the football to obtain the time information for starting and stopping dispensing, so that the dispensing mechanism dispenses when the non-dispensed joint passes through the dispensing processing point, and stops dispensing when the dispensed joint or the non-joint area passes through the dispensing processing point. After obtaining the information, the control unit can control the mechanisms according to the information that can be used to control the mechanisms and the information that can be used to control without calculation in the storage unit. In the processing preparation stage, the football is positioned to the specified processing point by the positioning system according to the position information in the storage unit, the clamping mechanism clamps the football, and the dispensing mechanism reaches the dispensing processing point. In the processing start stage, the rotary mechanism and the rotation mechanism control the rotation of the football according to the rotation information and the time information provided by the calculation unit, so that the joint on the surface of the football passes through the dispensing processing point at a constant speed, and the dispensing mechanism performs dispensing operation. When the dispensing processing point needs to pass through the part that does not need dispensing operation, the dispensing mechanism stops dispensing operation. When the joint that needs dispensing operation is located at the dispensing processing point, the dispensing mechanism continues dispensing operation.

[0010] Optionally, the control system further comprises a camera unit, which is used to obtain real-time position information of the joint on the surface of the football in rotation and transmit the real-time position information to the calculation unit. When the real-time position information transmitted by the camera unit deviates from the dispensing processing point, the calculation unit modifies the rotation path of the football to ensure that the joint line on the surface of the football returns to the position of the dispensing processing point.

[0011] By adopting the technical scheme, the camera unit can identify the position of the joint seam on the football surface and transmit real-time position information of the joint seam to the computing unit. The computing unit can compare the real-time position information of the joint seam with position information of the dispensing processing point. If the real-time position information of the joint seam deviates from the position information of the dispensing processing point, the computing unit modifies the rotation path of the football according to the real-time position information of the joint seam, so as to re-calculate the rotation information of the rotary clamping mechanism and the rotation mechanism and the time information of the dispensing mechanism for starting and stopping the dispensing operation according to the newly generated rotation path of the football. The control unit controls the rotation of the rotary clamping mechanism and the rotation mechanism and the dispensing operation of the dispensing mechanism according to the newly calculated rotation information and time information. The dispensing machine is more accurate in dispensing operation on the joint seam of the football surface by adding the camera unit and increasing the correction capability of the computing unit, so as to avoid the influence of accidental collision or shaking on the dispensing operation and ensure the quality stability of the football product.

[0012] Optionally, the rotary clamping mechanism comprises a clamping mechanism and a rotating mechanism. The clamping mechanism comprises a connecting plate, two chuck arms and two piston chucks. The two ends of the connecting plate are respectively fixedly connected with one chuck arm. The two chuck arms are parallel to each other. The two piston chucks are arranged opposite to each other. The ends of the two chuck arms away from the connecting plate are respectively fixed with one piston chuck. The piston chucks can rotate relative to the chuck arms. Each piston chuck can be extended and retracted through one piston. When the football located at the designated processing point is clamped, the two pistons are extended towards each other. When the processed football is released, the two pistons are retracted towards each other. The rotating mechanism comprises a product rotating structure and a rotating servo motor. The product rotating structure is installed on one of the piston chucks and can be rotated in the front-back direction by the rotating servo motor. The product rotating structure drives the piston chuck to rotate and in turn drives the football to rotate. The control unit controls the rotation angle and speed of the product rotating structure by controlling the output of the servo motor, so as to control the rotation angle and speed of the football in the front-back direction. The rotating mechanism comprises a connecting plate rotating mechanism and a rotating servo motor. The connecting plate rotating mechanism is connected to the side of the connecting plate away from the chuck arms and can be rotated in the left-right direction. The rotation angle is not more than 180 degrees. The connecting plate rotating mechanism drives the connecting plate to rotate, so as to drive the entire rotary clamping mechanism to rotate and in turn drive the football to rotate in the left-right direction. The rotating servo motor is used to drive the connecting plate rotating mechanism to rotate. The control unit controls the rotation angle and speed of the connecting plate rotating mechanism by controlling the output of the rotating servo motor, so as to control the rotation angle and speed of the football in the front-back direction.

[0013] By adopting the above technical scheme, the connecting plate is used for fixedly connecting the two chuck arms, so that the two chuck arms are always in a relatively static state. When the rotating mechanism rotates the rotating clamping mechanism, the connecting plate can prevent the chuck arms from moving relatively, thereby ensuring that the football is always stably controlled. The parallel chuck arms can enable the clamping mechanism to be clamped on the two sides corresponding to the football, so as to improve the stability of clamping and keep the football clamped regardless of the angle of rotation. The piston chuck is used for controlling the football without damaging the football. The disc-shaped structure can better adapt to the curvature of the surface of the football and will not excessively squeeze the football during clamping, thereby avoiding deformation of the football due to squeezing and ensuring the accuracy of the dispensing operation. The piston on the piston chuck can achieve the purpose of clamping and releasing the football by controlling the relative movement of the piston chuck. After the dispensing operation is completed, the piston chuck can be used to replace the football product. The piston chuck can rotate freely relative to the chuck arm. The piston chuck needs to be able to rotate relative to the chuck arm because the football needs to rotate relative to the chuck arm for processing. The product rotating structure is installed on the piston chuck at one end. The rotation of the product rotating structure can be controlled by controlling the rotation of the piston chuck, thereby controlling the rotation of the football. The rotating servo motor makes the rotation of the product rotating structure more accurate and fast. The rotating servo motor is controlled by the control unit. The control unit gives the rotating mechanism rotation information through the calculation unit. The angle and speed of the rotation of the product rotating structure are controlled through the rotating servo motor, thereby controlling the rotation of the football in the front-rear direction. The connecting plate rotating structure can control the rotation of the football in the left-right direction by controlling the rotation of the connecting plate, thereby controlling the rotation of the football in the left-right direction through the chuck arm and the piston chuck. Since the dispensing processing point is located directly above the football, the rotation angle of the connecting part rotating structure cannot exceed 180 degrees. However, since there is a rotating structure, the product dispensing operation will not be affected even if the rotation angle does not exceed 180 degrees. The rotating servo motor accurately and quickly controls the rotation of the connecting plate rotating structure. The control unit gives the rotating mechanism rotation information through the calculation unit. The angle and speed of the rotation of the connecting plate rotating structure are controlled through the rotating servo motor, thereby controlling the rotation of the football in the left-right direction. The rotating clamping mechanism and the rotating mechanism jointly control the football product, so that all the seams on the surface of the football can pass through the dispensing processing point at a specified speed, and the seams can be completely dispensed.

[0014] Optionally, the positioning mechanism comprises a positioning plate, a cylinder and a positioning needle. The cylinder comprises a cylindrical cylinder body, a piston moving in the cylinder body and a piston rod connected to the piston. The cylinder body is perpendicular to the positioning plate and is fixed to the positioning plate. The piston rod extends out of the cylinder body away from the positioning plate and extends along the length direction of the cylinder body away from the positioning plate. The positioning needle is fixed to the piston rod in the movement direction of the piston rod away from the positioning plate and is used for inserting into the inflation hole of the football to fix the football. The control unit can control the movement of the cylinder according to the specified processing point position information stored in the storage unit, so that the positioning needle positions the football at the specified processing point.

[0015] By adopting the technical scheme, the positioning plate can be used for fixing the air cylinder; the air cylinder is used for enabling the positioning needle to move up and down, and the piston moves to drive the piston rod to move by controlling the air pressure in the air cylinder by the control unit, so as to control the positioning needle to position the football at the specified processing point; when the football is controlled by the rotating clamping mechanism, the piston moves downward, so that the positioning needle is separated from the football, to avoid hindering the dispensing operation; the positioning needle is fixed by being pierced into the inflation hole of the football, so that the football is controlled in a simple, fast and non-destructive manner, the process of positioning the football at the specified processing point is simplified, and the processing efficiency is improved.

[0016] Optionally, the dispensing mechanism comprises a glue head handle, a glue barrel, a dispensing machine and an adjusting mechanism; the glue head handle is used for dispensing operation on the joint of the football surface, and can start or stop the dispensing operation in real time; the glue barrel is used for storing raw glue; the dispensing machine comprises a raw glue pipe, and is used for sucking the raw glue from the glue barrel through the raw glue pipe and conveying the raw glue to the glue head handle for dispensing operation; the adjusting mechanism comprises a guide rail and an extension plate, the extension plate is perpendicular to the guide rail and can move on the guide rail, and the extension plate is fixed with the glue head handle parallel to the guide rail at one end away from the guide rail; the control unit can control the movement of the extension plate on the guide rail according to the position information and the dispensing speed information of the dispensing processing point stored in the storage unit, so that the glue head handle is located at the dispensing processing point for dispensing operation, and the speed of conveying the raw glue from the dispensing machine to the glue head handle is controlled, so as to control the dispensing speed of the glue head handle; the control unit can control the start or stop of the dispensing operation of the glue head handle according to the time information of the start and stop of the dispensing operation of the dispensing mechanism calculated by the calculation unit.

[0017] By adopting the technical scheme, in the processing preparation stage, the control unit controls the movement of the extension plate on the guide rail, so that the glue head handle moves to the dispensing processing point; in the processing stage, the dispensing machine can suck the raw glue from the glue barrel and convey the raw glue to the glue head handle at a specified speed under the control of the control unit, so that the glue head handle can uniformly dispense the glue on the joint of the football surface; when the joint of the football surface moves away from the dispensing processing point, the glue head handle stops the dispensing operation under the control of the control system, and starts the dispensing operation again when the joint needing dispensing rotates to the dispensing processing point; the dispensing mechanism can uniformly dispense the glue on the football at the dispensing processing point, and stop the dispensing operation when the football surface not needing dispensing rotates to the dispensing processing point, which is beneficial to the quality stability of the football product.

[0018] Optionally, the connecting plate further comprises a connecting slide rail and two moving plates, the connecting slide rail extends to both sides along the length direction of the connecting plate, the back of the connecting slide rail is fixed with the connecting plate rotating structure, the centers of the two moving plates are equal to the distance from the connecting point of the connecting slide rail and the connecting plate rotating structure and are equal distance matched to move on the connecting slide rail, when one moving plate moves away from or approaches the connecting point of the connecting slide rail and the connecting plate rotating structure, the other moving plate also moves away from or approaches the connecting point of the connecting slide rail and the connecting plate rotating structure, and the moving distance and speed are equal, each chuck arm is fixed to one end of the moving plate away from the connecting point of the connecting slide rail and the connecting plate rotating structure; the storage unit is further used to store the position information of the specified processing points of different sizes of footballs, the position information of the dispensing processing points and the position information of the corresponding moving plates, and the surface seam line information of different seam footballs; the control unit can further control the moving plates to move to the corresponding moving plate positions along the connecting slide rail according to the position information of the moving plates stored in the storage unit.

[0019] By adopting the above technical scheme, the two moving plates and the connecting slide rail can enable the rotating clamping mechanism to clamp different sizes of footballs, thereby increasing the applicability of the dispensing machine, the centers of the two moving plates are equal to the distance from the connecting point of the connecting slide rail and the connecting plate rotating structure and are equal distance matched to move on the connecting slide rail, which can enable the upper and lower end points of the football to be always on the same straight line as the football rotating point when clamping different sizes of footballs, the football rotating point is the center point around which the football rotates when being controlled to rotate, and thus when processing different sizes of footballs, the positions of the specified processing points and the dispensing processing points only need to move in the length direction of the straight line, so that as long as the guide rail and the air cylinder are parallel to the straight line, the operation of adjusting the positions of the positioning mechanism and the dispensing mechanism when processing different sizes of footballs can be avoided, and the dispensing operation on different sizes of footballs is more convenient; since the position of the rotating clamping mechanism does not change, i.e. the position of the football rotating point does not change, therefore when processing different sizes of footballs, what needs to be changed is the positions of the pointing processing points and the dispensing processing points, and thus the position information of the pointing processing points of different sizes of footballs, the position information of the dispensing processing points and the position information of the moving plates need to be stored in the storage unit, so that the control unit can control the positioning needle, the glue head handle and the moving plate to move to the specified positions according to the position information, the surface seam information of different seam footballs is stored in the storage unit, the calculation unit can calculate the respective football rotating paths according to the respective seam information, and then combines other required information to calculate the rotating information of the respective rotating mechanisms and the dispensing time information of the dispensing mechanism, so as to achieve the purpose of processing different types of sizes and seam footballs, thereby increasing the application range of the football dispensing machine.

[0020] Optionally, the positioning needle is further used to detect the internal air pressure of the football and perform the inflation and deflation treatment on the football, so as to control the internal air pressure of the processed football to maintain the working air pressure.

[0021] By adopting the technical scheme, the so-called working air pressure is the pressure under which the football will not be deformed due to clamping when the rotating clamping mechanism clamps the football. The working air pressure should not be too large or too small. Since the rotating clamping mechanism clamps the football to control the football for processing, a certain pressure needs to be applied to the football. Therefore, if the internal air pressure of the football is too small, the dispensing machine may not be able to fix the football. If the air pressure is insufficient or too large, the rotating clamping mechanism may cause the football to deform when clamping the football, and thus the actual rotation route of the joint seam during rotation may not match the joint seam path information in the control system, causing the dispensing operation to deviate, or the calculation mechanism needs to frequently correct the joint seam route, resulting in low processing efficiency. Therefore, the internal pressure of the football is at a suitable value, which is beneficial to the dispensing accuracy and efficiency of the football processing. The positioning needle can inflate and deflate the football, and the internal air pressure of the football can be maintained at the working air pressure, so as to ensure the accuracy of the dispensing operation and efficient processing.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. Under the control of the control system, the rotating clamping mechanism and the rotating mechanism accurately control the rotation of the football, and the dispensing structure uniformly dispenses the joint seam of the football at the dispensing processing point, thereby saving labor costs and efficiently processing the football product while ensuring stable quality.

[0024] 2. The camera unit is added to monitor the processing process, and the deviation of the joint seam from the dispensing processing point caused by unexpected situations during processing can be corrected, thereby ensuring the accuracy of the dispensing operation and the anti-interference ability of the dispensing machine.

[0025] 3. The guide rail and the moving plate are added to the connecting plate, and the information of different sizes and joint seams of the football is added to the control system, so that the dispensing machine can process footballs of different sizes and joint seams, thereby improving the applicability of the dispensing machine.

The protective cover 22 can prevent the internal raw glue from splashing outside during processing, causing additional cleaning burden, and can also prevent external objects from impacting the glue dispenser and the football during processing, thereby avoiding affecting the normal processing process and ensuring the smooth completion of the gluing operation.

[0035] With reference to Figure 1 and Figure 2 , the box 1 further comprises a gas source port 71, an electric control box 72, control buttons 73, a three-color lamp 74, a pulley 75 and a supporting device 76. The gas source port 71 is used to provide gas for the pneumatic part of the driving device; the electric control box 72 is installed with a control system 8 and a self-checking program. The self-checking program is used to check whether there is a fault in the operation of each mechanism before starting processing, and to position each mechanism at the initial position. If a fault occurs, the three-color lamp 74 will transmit fault information. After manual troubleshooting, the self-checking program is performed again. If there is no fault, the three-color lamp will transmit normal information, notifying the user that subsequent operations can be performed. The control buttons 73 can be used to start and stop the work of the glue dispenser, and can also select information in different storage units 81 for use by the calculation unit 83 according to different types of processed footballs, so that the glue dispenser can process footballs of different sizes and different seams. The three-color lamp 74 can be used to display the working state of the glue dispenser. When the glue dispenser is in a working state, a pause state or a fault state, the three-color lamp 74 can transmit the state information of the glue dispenser to the outside world by displaying different colored lights. The pulley 75 is installed on the four corners of the bottom of the rectangular box 1. Due to the large mass of the glue dispenser, it is difficult to move by carrying, and the shaking during carrying and the vibration during placement may cause the position of each mechanism to deviate, resulting in operation errors. The pulley 75 can move the glue dispenser by sliding to avoid vibration, which facilitates movement and avoids position deviation of each mechanism caused by vibration. The supporting device 76 can be used to fix the glue dispenser. After the glue dispenser is moved to the designated position by the pulley 75, it needs to be fixed, otherwise in the movable state, the processing of the glue dispenser is easy to be disturbed by the outside world and produce errors. The supporting device 76 can fix the glue dispenser, so that the glue dispenser cannot easily move, thereby enhancing the anti-interference ability of the glue dispenser and ensuring the smooth and accurate processing process.

[0036] Reference Figure 3The positioning mechanism 6 includes a positioning needle 61, a cylinder 62 and a positioning plate 63.
