Description

Technical Field

[0001] The utility model relates to the technical field of conveying production lines, and particularly relates to a material turnover and transmission device and a feeding device. Background Art

[0002] A conveying production line is composed of components such as a conveyor belt, a tray, and a manipulator. Products are stored in the tray and brought to the grasping point of the manipulator after the tray rotates. After being grasped by the manipulator, they are placed on the conveyor belt and sent to the next process through the conveyor belt. Generally, various sensors, electric cylinders and other components are installed on the manipulator to control the manipulator to grasp products from the tray and then automatically place the products on the conveyor belt, greatly improving the production efficiency.

[0003] When some products are batch-fed into the tray, it is not possible to ensure whether a certain surface of them is facing up or down, such as the processing surface and the non-processing surface (hereinafter collectively referred to as the front or the back), etc. When the manipulator grasps the product from the tray, for example, when the front of the product is required to face up in the next process, it is possible that the front of the workpiece is facing down. When being conveyed to the next process through the conveyor belt, due to the inconsistent orientations of these products, the next process cannot work properly, affecting the production efficiency. Summary of the Invention

[0004] In order to solve the above problems, improve the production efficiency of the conveying line, and at the same time enable the conveyor belt to have a commutation function for products, the utility model provides a material turnover and transmission device and a feeding device. The material turnover and transmission device includes a frame. A gearbox is installed at the left end of the frame, and a motor is installed on the gearbox. A conveying roller is installed at each of the left and right ends of the frame. A conveyor belt is installed between the two conveying rollers. The left conveying roller is driven by the gearbox. The conveyor belt is located inside the frame and conveys to the right. A feeding hopper is installed on the left side of the frame. The feeding hopper is located above the left side of the conveyor belt. The top end of the feeding hopper is provided with a feeding port, and the bottom end of the feeding hopper is provided with a discharging port. The discharging port is bent in the direction of the conveyor belt conveying materials to the right. An inclined surface is provided in the feeding port. The inclined surface is located above the feeding port and inclines to the left.

[0005] As a further preference, two front and rear baffles are fixed to the top of the frame. One end of the two baffles reaches the left end of the conveyor belt, and the other end of the two baffles reaches the right end of the conveyor belt. The conveyor belt and the discharging port are located between the two baffles.

[0006] As a further preference, a vertical surface is provided on the left side of the feeding hopper. The inclined surface is inclined in the right direction of the vertical surface.

[0007] As a further preference, a first transition part is provided between the inclined surface and the discharge port. The first transition part is arc-shaped, and the arc is bent towards the discharge port. A second transition part is provided between the vertical surface and the discharge port. The second transition part is also arc-shaped, and the bending direction of the arc is the same as that of the first transition part.

[0008] As a further preference, the circular arc curvature of the first transition part is greater than or equal to that of the second transition part.

[0009] As a further preference, a bearing part extending obliquely towards the conveyor belt is formed at the end of the second transition part, and the end of the bearing part forms the discharge port.

[0010] As a further preference, the vertical distance from the discharge port to the conveyor belt is less than the length of the material in the conveying direction of the conveyor belt after being turned over.

[0011] As a further preference, a carrier is fixed on the frame. The carrier extends vertically upwards. A horizontal part is provided at the right end of the feed port, and the horizontal part is fixed on the vertical top end of the carrier.

[0012] On the other hand, the present utility model also provides a feeding device including the above-mentioned material turning and conveying device.

[0013] The beneficial effects of the present utility model compared with the prior art are as follows:

[0014] If the product is face up, the manipulator directly places the product on the conveyor belt. The conveyor belt conveys the product to the right and transports the product to the next process. If the product picked up by the manipulator from the tray is face down, the manipulator puts the product into the feed hopper through the feed port. After discharging from the discharge port, it falls on the left end of the conveyor belt and is transported to the right by the conveyor belt and then enters the next process. As shown in the figure, since the discharge port is bent towards the direction of the conveyor belt transporting the material to the right, when the product discharges towards the discharge port in the inner cavity of the feed hopper, it will first change its orientation in the feed hopper, changing its face from down to up, and finally falls on the conveyor belt from the discharge port and is transported to the right by the conveyor belt to meet the process requirements in the next process. On the contrary, if the product is required to be face down after being placed on the conveyor belt, the manipulator picks up the product from the tray. If the product is face down, the manipulator directly places the product on the conveyor belt. The conveyor belt conveys the product to the right and transports the product to the next process to meet the assembly requirements. If the product picked up by the manipulator from the tray is face down, the manipulator puts the product into the feed hopper through the feed port. When discharging from the discharge port, it automatically changes to face down, and finally falls on the left end of the conveyor belt and is transported to the right by the conveyor belt and then enters the next process to meet the process requirements. This commutation structure only utilizes the structure form of the upper-wide and lower-narrow of the feed hopper and does not add other commutation functions to the feed hopper. The structure is simple. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0021] In one embodiment, Figures 1-4 As shown:

[0022] This embodiment provides a material turning and conveying device, including a frame 1, which is fixed to the main frame of the conveyor line during actual assembly. The main frame is also equipped with a control panel, etc., for issuing instructions to a system on the conveyor line. Figure 1The description is made in the orientation shown by the middle material turning and conveying device. A gearbox 2 is installed at the left end of the frame 1, and a motor 3 is installed on the gearbox 2. A conveying roller 4 is installed at each of the left and right ends of the frame 1. A conveyor belt 5 is installed between the two conveying rollers 4. The left conveying roller 4 is driven on the gearbox 2. When the motor 3 is powered on, the gear system in the gearbox 2 works, and the gear system drives this conveying roller 4 to rotate. This conveying roller 4 is the power source and transmits power to the other conveying roller 4 through the conveyor belt 5, so that the conveyor belt 5 conveys to the right between the two conveying rollers 4. The product placed on the conveyor belt 5 and conveyed to the right represents bringing the product into the next process. In addition, in the present utility model, a feed hopper 6 is also installed on the left side of the frame 1. The feed hopper 6 is located above the left side of the conveyor belt 5. The top end of the feed hopper 6 is provided with a feed inlet 7, and the bottom end of the feed hopper 6 is provided with a discharge outlet 8. When in use, the product enters through the feed inlet 7 and then is discharged through the discharge outlet 8. Different from the prior art, the present utility model defines the orientation structure of the discharge outlet 8 and the positional relationship with the conveyor belt 5. The discharge outlet 8 in the present utility model is curved and curved in the direction of the conveyor belt 5 conveying materials to the right. In addition, an inclined surface 10 inclined in the direction opposite to the feeding direction of the conveyor belt 5 is provided in the feed inlet 7. The inclined surface 10 is located above the feed inlet 7 and inclined to the left.

[0023] The above-mentioned feed hopper 6 is applied in the present utility model, which is mainly reflected in the following principle: If it is required that the front (or processing surface, assembly surface) of the product faces upward after being placed on the conveyor belt 5, the manipulator picks up the product from the tray. If the front of the picked-up product also faces upward, the manipulator directly places the product on the conveyor belt 5 under the control of the sensor, and the conveyor belt 5 conveys to the right and conveys the product to the next process to the right. If the front of the product picked up by the manipulator from the tray faces downward, the manipulator puts the product into the feed hopper 6 through the feed inlet 7, and after discharging from the discharge outlet 8, it falls on the left end of the conveyor belt 5, and after being conveyed to the right by the conveyor belt 5, it enters the next process, as Figure 4 shown. Since the discharge outlet 8 is curved in the direction of the conveyor belt 5 conveying materials to the right, when the product discharges towards the discharge outlet 8 in the inner cavity of the feed hopper 6, the orientation of the product will be changed in the feed hopper 6 first, so that its front changes from facing downward to facing upward, and finally it falls on the conveyor belt 5 from the discharge outlet 8 and is conveyed to the right by the conveyor belt 5 to meet the process requirements in the next process. On the contrary, if it is required that the reverse side of the product faces upward after being placed on the conveyor belt 5, the manipulator picks up the product from the tray. If the reverse side of the product faces upward, the manipulator directly places the product on the conveyor belt 5, and the conveyor belt 5 conveys to the right and conveys the product to the next process to meet the assembly requirements. If the reverse side of the product picked up by the manipulator from the tray faces downward, the manipulator puts the product into the feed hopper 6 through the feed inlet 7, and when discharging from the discharge outlet 8, it automatically changes to the reverse side facing upward, and finally falls on the left end of the conveyor belt 5, and after being conveyed to the right by the conveyor belt 5, it enters the next process to meet the process requirements.

[0024] As Figure 1 , Figure 4 shown, a vertical surface 11 is provided on the left side of the feed hopper 6, and the inclined surface 10 is located in the inclined direction on the right side of the vertical surface 11. A first transition portion 12 is provided between the inclined surface 10 and the discharge port 8. The first transition portion 12 is arc-shaped, and the arc is bent towards the discharge port 8. A second transition portion 13 is provided between the vertical surface 11 and the discharge port 8. The second transition portion 13 is also arc-shaped, and the bending direction of the arc is the same as that of the first transition portion 12. Thus, when the product enters the feed hopper 6 from the feed port 7, first, the product slides along the inclined surface 10 towards the left side. After it slides down under the guidance of the first transition portion 12, its bottom side continues to slide down, and first, its bottom side impacts on the vertical surface 11. Under the blocking of the vertical surface 11 and the action of gravity, then the orientation is changed, and it continues to slide down along the second transition portion 13. Since the opening of the discharge port 8 faces the transmission direction of the conveyor belt 5 (transmitting to the right in the figure), the product changes its orientation in the narrow space where the second transition portion 13, the first transition portion 12, and the vertical surface 11 are located, and finally discharges from the discharge port 8 and falls onto the conveyor belt 5. The entire orientation-changing work is completed in the feed hopper 6, and this orientation-changing structure in the feed hopper 6 can be formed in one step only by using its upper-wide and lower-narrow structural form, that is, structures such as the inclined surface 10, the first transition portion 12, and the second transition portion 13 can be made with the bending process of the feed hopper 6, without adding other orientation-changing functions to the feed hopper 6 additionally, and the structure is simple. Moreover, the feed hopper 6 is located at one end of the conveyor belt 5. When the orientation of the product picked up by the manipulator from the tray meets the requirements, it can be directly placed on the conveyor belt 5 and conveyed to the next process. When the orientation of the product picked up by the manipulator from the tray does not meet the requirements, it can be directly placed into the feed hopper 6 nearby to complete the orientation change, and then it can fall onto the conveyor belt 5 and be conveyed to the next process. The structure is reasonably distributed and is convenient to cooperate with the manipulator. Since the positions of the conveyor belt 5 and the feed hopper 6 are in the overall position, when the manipulator makes a turning motion, the requirements for the turning angle or the step distance are relatively low, which is beneficial to the assembly of the transmission line equipment.

[0025] In this embodiment, it is set that the arc curvature of the first transition part 12 is greater than or equal to the arc curvature of the second transition part 13. This setting provides space for the turnover of the material and enables the turnover material to smoothly slide along the second transition part 13 to the discharge port 8. In order to enable the turnover material to smoothly fall onto the conveyor belt 5, a bearing part 16 extending obliquely towards the conveyor belt 5 is formed at the end of the second transition part 13, and the discharge port 8 is formed at the end of the bearing part 16. Further, it is also set that the vertical distance from the discharge port 8 to the conveyor belt 5 is less than the length of the material in the conveying direction of the conveyor belt 5 after turnover. This setting enables the material to be output to the conveyor belt based on the traction of the conveyor belt 5 after being output from the discharge port 8. On the one hand, this setting avoids the re-turnover of the material after being output from the discharge port 8 (especially when the material is light), and at the same time effectively avoids the damage to the material and the conveyor belt caused by the falling of the material.

[0026] As Figure 1 shown, a carrier 14 is fixed on the frame 1. The carrier 14 is perpendicular upward. A horizontal part 15 is provided at the right end of the feed inlet 7, and the horizontal part 15 is fixed on the vertical top end of the carrier 14. The carrier 14 horizontally supports the horizontal part 15, improves the strength of the horizontal part 15, provides support strength from the horizontal part 15 to the feed inlet 7, and provides strength from the feed inlet 7 to the entire feed hopper 6.

[0027] As Figure 1 、 Figure 2 shown, two front and rear baffles 9 are fixed on the top of the frame 1. One ends of the two baffles 9 reach the left end of the conveyor belt 5, and the other ends of the two baffles 9 reach the right end of the conveyor belt 5. The conveyor belt 5 and the discharge port 8 are located between the two baffles 9. The two baffles 9 form a shield on the front and rear sides of the conveyor belt 5 to prevent the product from falling off downward during transportation.

[0028] It should be further noted that the manipulator and the tray mentioned in the present invention are applied to the transmission line and together with components such as the conveyor belt 5 constitute a conveying system for product materials. When the tray is mostly a rotary type, the product is placed in the tray, and after the tray rotates, it is brought to a position where the manipulator can pick it up. The tray can also be a vibrating tray, etc. Such a tray and manipulator applied to the production line (or transmission line) are inseparable from control systems such as servo circuits. When they cooperate, the tray rotates to a certain angle and stops rotating. After the manipulator picks up the product, the tray rotates again to transfer the next product to a position where the manipulator can pick it up after returning. It can be seen that the manipulator and the tray are prior arts, and their structures and control systems are also prior arts. For example, an identification sensor is provided on the manipulator to identify the front and back sides of the product in the present invention, so as to selectively place the product into the feed hopper 6 or the conveyor belt 5. Since they are all prior arts, the present invention will not elaborate on them in detail.

[0029] On the other hand, this embodiment also provides a feeding device including the above-mentioned material turnover and transmission device.

[0030] The above orientation references do not represent the specific orientations of the components in this embodiment. This embodiment is only for the convenience of describing the solution and is set with relative descriptions with reference to the orientations in the figures. In essence, the specific orientations of the components are based on their actual installation, actual use, and the habitual orientation descriptions of those skilled in the art. This is hereby stated.

[0031] The specific embodiments described above have further elaborated on the utility model purpose, technical solution, and beneficial effects of the present utility model. It should be understood that the above is only the specific embodiment of the present utility model and is not used to limit the protection scope of the present utility model. It is particularly pointed out that for those skilled in the art, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
