Description

Technical Field

[0001] This utility model belongs to the field of mechanical conveying technology for sorting machines, and in particular relates to a multi-layer material tray feeding device for storage and transmission. Background Technology

[0002] Current automated sorting machines use stacked trays for storing chips, which can only hold a single type of chip. This means that when faced with multiple bins of chips, the sorting process has to be repeated multiple times to meet the requirements, which severely impacts production efficiency. Utility Model Content

[0003] In view of this, the present invention aims to propose a multi-layer material tray feeding device for storage and transmission, so as to solve the problem that the current automated sorting machine material tray can only store a single type of chip, resulting in low working efficiency when dealing with multiple bin chips.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A multi-layer tray feeding device for storage and transmission includes a main body and a hopper mechanism, a push-out mechanism, a conveyor rail mechanism, a Z-axis drive mechanism, a Y-axis drive mechanism, a display component, a button component, and a manual tray changing component mounted on top of it. The manual tray changing component is used to pick up and put down trays. The hopper mechanism is used to store trays. The push-out mechanism is mounted on top of the hopper mechanism to push the trays to the conveyor rail mechanism. The conveyor rail mechanism is driven by the Y-axis drive mechanism. The conveyor rail mechanism is also provided with a push-in mechanism to assist the trays in returning to the hopper mechanism. The Z-axis drive mechanism is used to drive the hopper mechanism to move up and down. The button component is used to control the up and down movement of the Z-axis drive mechanism. The display component is used to display the quantity and status of the trays.

[0006] Furthermore, the multi-layer tray feeding device for storage and transmission also includes a guide mechanism for maintaining the horizontal orientation of the internal trays.

[0007] Furthermore, the multi-layer tray feeding device for storage and transmission also includes a pressing mechanism, which is installed on one side of the conveying guide mechanism and is used to press the tray.

[0008] Furthermore, the hopper mechanism includes a frame structure composed of a left baffle, an upper baffle, a right baffle, and a lower baffle connected in sequence. The frame is used to store material trays. The inner walls of the left and right baffles are provided with several support plates for placing material trays. Each support plate has a slot above it. The main body is provided with a sensor for detecting whether there is a material tray in the slot.

[0009] Furthermore, the main body includes a base plate and an active wheel and a support seat mounted on it. The active wheel is driven by a Z-axis drive mechanism, and the transmission unit drives the support seat to move up and down. The support seat is located below the hopper mechanism and is slidably connected to the guide rail. When the Z-axis drive mechanism outputs power, it drives the support seat to move up and down, thereby driving the hopper mechanism to move up and down.

[0010] Furthermore, the ejection mechanism includes a base mounted on the main body. An ejection cylinder and a swing rod are fixedly mounted on the top of the base. A push rod is fixedly mounted on the movable end of the ejection cylinder. A push rod extension rod is fixedly mounted on the end of the push rod, and the middle part is hinged to the swing rod, so that when the ejection cylinder is activated, it drives the push rod, the push rod extension rod, and the swing rod to move together, and converts the original linear motion into a vertical circular motion.

[0011] Furthermore, the conveying guide rail mechanism includes a conveying base plate and a conveying drive wheel disposed above it. A pair of rails are symmetrically installed on both sides of the conveying base plate, and a conveying unit is installed on the outer side of one of the rails. The conveying unit is driven by a Y-axis drive mechanism. A pushing mechanism is also installed above the conveying base plate. A material tray is placed above the guide rail, and the material tray is located above the pushing mechanism.

[0012] Furthermore, the Y-axis drive mechanism includes a motor and a synchronous belt. The motor is installed below the conveying base plate. The conveying unit includes a conveying drive wheel, a flat belt, and a follower wheel. The conveying drive wheel and the follower wheel form a conveying structure through the flat belt. The conveying drive wheel is also connected to the drive end of the motor through the synchronous belt. The motor transmits power to the top of the conveying drive wheel through the synchronous belt, thereby driving the flat belt and the follower wheel to move, so that the conveying guide rail mechanism can convey the material tray in the front and back directions.

[0013] Furthermore, the pushing mechanism includes a pushing cylinder and a pushing rod. The pushing cylinder is located above the conveying plate. The movable end of the pushing cylinder is rotatably connected to the pushing rod and a spring is provided between them. A baffle is installed between the pushing cylinder and the movable end of the cylinder. An adjusting rod for adjusting the opening and closing angle of the pushing rod is also installed on the movable end of the pushing cylinder, and the adjusting rod is located below the pushing rod.

[0014] Furthermore, the pressure plate mechanism includes a support and an adjusting plate. The support is fixedly connected to the conveying base plate and detachably connected to the adjusting plate on one side. An adjusting screw for adjusting the height of the adjusting plate is provided above the adjusting plate. A spring fixing seat, a transition plate, and a pressure plate follower wheel are installed in sequence below the adjusting plate. The pressure plate follower wheel contacts the top of the material tray. A pressure plate spring is provided inside the spring fixing seat.

The manual tray changing component 12 is used to pick up and put away trays. The hopper mechanism 1 is used to store trays. The ejection mechanism 3 is mounted on top of the hopper mechanism 1 and is used to eject the trays to the conveyor rail mechanism 5. The conveyor rail mechanism 5 is driven by the Y-axis drive mechanism 8. The conveyor rail mechanism 5 is also equipped with a push-in mechanism 6 to assist the trays in returning to the hopper mechanism 1. The Z-axis drive mechanism 7 is used to drive the hopper mechanism 1 to move up and down, facilitating the ejection of trays. The button component 11 is used to control the up and down movement of the Z-axis drive mechanism 7. The button component 11 is connected to the switch of the Z-axis drive mechanism 7, thereby controlling the up and down movement of the Z-axis drive mechanism 7, which in turn drives the hopper mechanism 1 to move up and down. The display component 10 is used to display the number of empty trays and trays with material.

[0038] The display component 10 includes a display screen and a controller, which is a PLC. The main body 2 is equipped with several sensors. The sensors detect the quantity of empty and loaded trays and transmit the information to the controller, which then displays it on the display screen. This process is existing technology and will not be described in detail here.

[0039] A multi-layer tray feeding device for storage and transfer also includes a guide mechanism 4 for maintaining the horizontal orientation of the internal trays.

[0040] A multi-layer tray feeding device for storage and transmission also includes a pressing mechanism 9, which is installed on one side of the conveying guide mechanism 5 to press the tray and ensure that the tray runs smoothly on the conveying guide mechanism 5.

[0041] The hopper mechanism 1 includes a frame structure composed of a left baffle 11, an upper baffle 13, a right baffle 15, and a lower baffle 16 connected in sequence. The frame is used to store the material tray A. The inner walls of the left baffle 11 and the right baffle 15 are each provided with several support plates 112 for placing the material trays. To facilitate loading, the two ends of the support plates 112 are provided with bevels. Each support plate has a slot 111 above it. The main body 2 is equipped with a sensor for detecting whether a material tray is present in the slot 111. The slot 111 is used to identify whether a material tray is present in the current magazine layer. In one or more embodiments, sliding units 12 are provided at the four corners of the upper baffle 11 and the lower baffle 16. The sliding units 12 cooperate with guide units to provide guidance. Preferably, the sliding units 12 are two mutually perpendicular pulleys. A handle 14 is also installed on the upper baffle 13, which facilitates manual movement of the hopper for maintenance.

[0042] The main body 2 includes a base plate 27 and a drive wheel 21, a tension wheel 22, a driven wheel 23, a support base 24, a belt 25, a guide rail 26, and a lifting arm 28 mounted on it. The drive wheel 21 is driven by a Z-axis drive mechanism 7 and drives the driven wheel 23 to rotate via the belt 25. The belt 25 can also drive the tension wheel 22 to rotate and drive the support base 24 to move up and down. The support base 24 is located below the hopper mechanism 1 and is slidably connected to the guide rail 26. When the Z-axis drive mechanism 7 outputs power, it drives the support base 24 to move up and down, thereby driving the hopper mechanism 1 to move up and down. Preferably, there are two guide rails 26 arranged symmetrically. The two guide rails 26 are connected at their lower ends by the lifting arm 28, which is used to maintain the stability of both ends of the guide rails 26. A guide mechanism 4 is also installed on the top of the main body 2. When the hopper moves up and down, the guide mechanism 4 is used to maintain the horizontal direction of the internal tray and increase the stability of the machine. Specifically, the guide mechanism 4 includes a first guide rod 41 and a second guide rod 42, both mounted on the base plate 27. Z-axis drive mechanism 7 is a motor.

[0043] Figure 5 For the ejection mechanism 3, the ejection cylinder is in the retracted state. Figure 6 The ejection mechanism 3 is in the extended position of the ejection cylinder. The ejection mechanism 3 includes a base 36 and a push rod extension rod 31, a push rod 32, a push rod connecting block 33, an ejection cylinder 34, and a swing rod 35 disposed above it. The base 35 is mounted on the main body 2. The ejection cylinder 34 and the swing rod 35 are fixedly mounted on the top of the base 35. The push rod 32 is fixedly mounted on the movable end of the ejection cylinder 34. The push rod extension rod 31 is fixedly mounted on the end of the push rod 32, and the middle part is hinged to the swing rod 35, so that when the ejection cylinder 34 is actuated, it drives the push rod 32, the push rod extension rod 31, and the swing rod 35 to move together, and converts the original linear motion into a vertical circular motion. Preferably, the ejection cylinder 34 is fixedly connected to the push rod 32 through the push rod connecting block 33.

[0044] The conveying guide mechanism 5 is used to convey the tray in the front and back directions. The conveying guide mechanism 5 includes a conveying base plate 57 and a conveying drive wheel 51, a flat belt 52, a follower wheel 53, a right rail 54, a left rail 55, and a connecting rod 56 arranged on it. A pair of rails are symmetrically installed on both sides of the conveying base plate 57. A conveying unit is installed on the outer side of one of the rails. The conveying unit is driven by the Y-axis drive mechanism 8. A pushing mechanism 6 is also installed above the conveying base plate 57. The tray is placed above the guide rail and is located above the pushing mechanism 6. In one or more embodiments, the Y-axis drive mechanism 8 includes a motor 81 and a synchronous belt 82. The motor 81 is mounted below the conveying base plate 57. The track includes a right track 54 and a left track 55, which are connected by a connecting rod 56. The conveying unit includes a conveying drive wheel 51, a flat belt 52, and a follower wheel 53. The conveying drive wheel 51 and the follower wheel 53 form a conveying structure through the flat belt 52. The conveying drive wheel 51 is also connected to the drive end of the motor 81 through the synchronous belt 82. The motor 81 transmits power to the top of the conveying drive wheel 51 through the synchronous belt 82, thereby driving the flat belt 52 and the follower wheel 53 to move, so that the conveying guide rail mechanism can convey the material tray in the front and back directions.

[0045] The pushing mechanism 6 includes a pushing cylinder 61, a pushing rod 62, a fixed base 63, a baffle 64, and an adjusting rod 65. The pushing cylinder 61 is located above the conveying base plate 57. The movable end of the pushing cylinder 61 is rotatably connected to the pushing rod 62, and a spring is provided between them. The baffle 64 is installed between the pushing cylinder 61 and the movable end of the cylinder. The movable end of the pushing cylinder 61 is also equipped with an adjusting rod 65 for adjusting the opening and closing angle of the pushing rod 62, and the adjusting rod 65 is located below the pushing rod 62. Preferably, the pushing cylinder 61 is fixedly connected to the conveying base plate 57 via the fixed base 63.

[0046] When the tray on the conveyor guide mechanism 5 needs to return to the hopper of the hopper mechanism 1, the pushing mechanism 6 will extend as follows: Figure 9 The conveying guide mechanism 5 assists in the process of the material tray on the conveying guide mechanism 5 entering the hopper. When the pushing cylinder 61 retracts, the upper surface of the pushing rod 62 remains horizontal with the pushing cylinder 61, so as not to interfere with the movement of the material tray on the conveying guide mechanism 5. When the pushing cylinder 61 extends, the lower surface of the pushing rod 62 remains horizontal with the pushing cylinder 61 under the action of the spring, so as to push the material tray from the conveying guide mechanism 5 into the hopper of the hopper mechanism 1. The adjusting rod 66 is used to adjust the opening and closing angle of the pushing rod.

[0047] The pressure plate mechanism 9 includes a support 91, an adjusting plate 92, a spring fixing seat 93, a transition plate 94, a pressure plate follower wheel 95, and an adjusting screw 96. The support 91 is fixedly connected to the conveying base plate 57, and one side is detachably connected to the adjusting plate 92. An adjusting screw 96 for adjusting the height of the adjusting plate 92 is provided above the adjusting plate 92. The spring fixing seat 93, the transition plate 94, and the pressure plate follower wheel 95 are sequentially installed below the adjusting plate 92. The pressure plate follower wheel 95 contacts the top of the material tray. A pressure plate spring is provided inside the spring fixing seat 93, which connects the adjusting plate 92 and the transition plate 94. The pressure plate spring is a compression spring. When the material tray moves in and out of the conveying guide mechanism 5, the pressure plate follower wheel 95 will directly contact the material tray. At this time, under the action of the pressure plate spring, a downward pressure is applied to the pressure plate follower wheel 95, thereby increasing the friction of the material tray on the conveying guide mechanism 5. This allows the material tray to run smoothly on the conveying guide mechanism 5.

[0048] Application Example: A robotic arm transports chips onto a conveyor rail mechanism 5. A tray is placed on top of the conveyor rail mechanism 5 to receive the chips. When the tray is full or empty, it is conveyed to the hopper 1 by a belt 52. The conveyor rail mechanism 5 has pressure plate mechanisms 9 on both sides. When the front half of the tray enters the conveyor rail, it contacts the lower edge of the pressure plate mechanism, where pressure is applied to ensure the tray adheres tightly to the conveyor belt, increasing friction and facilitating easier transport. Once the tray is in position within the hopper 1, the hopper 9 moves up and down under the drive of structure 2. When it reaches a designated position, the ejection mechanism 3 extends its ejection cylinder, pushing the tray out of the hopper 9. Simultaneously, the motor inside the conveyor rail mechanism 5 reverses, transporting the tray back onto the rail via a belt for the robotic arm to begin the next operation.

[0049] The working principle of a multi-layer tray feeding device for storage and transmission is as follows:

[0050] The hopper mechanism 1 is located inside the main body 2 and is connected to the Z-axis drive mechanism 7. The controller controls the Z-axis drive mechanism 7 to work. When the material tray in the hopper mechanism 1 reaches the designated position, the controller controls the ejection cylinder 34 to act. The ejection mechanism 3 pushes the material tray from the hopper mechanism 1 onto the conveyor guide mechanism 5. At this time, the pressure plate assembly 9 assists the conveyor guide mechanism 5. After the sorter completes the feeding action, the controller receives the signal from the sorter and drives the conveyor guide mechanism 5 through the Y-axis drive mechanism 8 to return the material tray to the hopper mechanism 1. At the same time, it controls the push-in cylinder 61 to work, so that the push-in mechanism 6 also assists in returning the material tray to the hopper mechanism 1. When the material tray needs to be removed, it can be moved up and down by the button assembly 11 to reach the tray exit position, which opens the manual tray changing assembly 12. The full tray is removed, the empty tray is placed in, and then the manual tray changing assembly 12 is closed. The Z-axis drive mechanism 7 and the Y-axis drive mechanism 8 set in the multi-layer tray feeding device for storage and transmission realize precise control of vertical and horizontal longitudinal movement. The Z-axis drive mechanism 7 drives the support seat 24 connected to the belt 25 to move up and down synchronously, ensuring the smooth lifting and lowering of the material box. The Y-axis drive mechanism 8 precisely controls the horizontal displacement of the material tray via the flat belt 52 connected to the conveyor rail. The main body 2 has a display panel of the display component 10 on its front, displaying the current output bin information. Next to the panel are buttons of the button component 11, which control the up and down movement of the hopper mechanism 1. A manual tray changing component 12 is located below the panel and can be raised for replacing a full tray. The mechanism is equipped with an ejector cylinder 34 and an infeed cylinder 61 on its inner and outer sides, forming a complete automated feeding and discharging system. When the ejector cylinder is activated, its push rod automatically extends, gently pushing the material tray located on the conveyor rail inside the machine into the material box; conversely, when the infeed cylinder is activated, the push rod accurately pushes the material tray back onto the conveyor rail, completing one material transfer process. A single mechanism can sort more than 14 bins of chips.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
