Description

Technical Field

[0001] The invention relates to the technical field of drinking water container processing equipment, and in particular to an automatic feeding mechanism for processing a water bowl. Background Art

[0002] In the process of animal husbandry, drinking water devices are very common, especially bowl-shaped drinking water devices, which are widely sought after for their simple structure and practical functions. The bowl-shaped drinking water device is referred to as a drinking water bowl, or a water bowl. The water bowl is usually an integrated structure consisting of a bowl body, a bowl mouth, and a bowl bottom. The bowl body is hollow and truncated, with a larger diameter at the bowl mouth and a smaller diameter at the bowl bottom. In the processing and manufacturing of the water bowl, a stamping forming method is generally used. Specifically, the circular sheet is sprayed with oil and coated, and then placed on a stamping machine. After being stamped and formed, an integrated water bowl is produced, and then the water bowl is collected by a collecting mechanism.

[0003] However, in the existing water bowl processing process, the oil spraying and loading of the material sheets are all done manually by operators, and the entire operation process is very inefficient. In order to improve the overall operation efficiency, the oil spraying and loading work often requires multiple people to complete, which is a waste of manpower. Summary of the invention

[0004] The problem solved by the present invention is to overcome at least one defect of the above prior art and provide a highly efficient automatic feeding mechanism for processing water bowls by machine instead of manual labor.

[0005] In order to solve the above problems, the present invention provides an automatic feeding mechanism for water bowl processing, which includes a frame, and the frame is provided with a feeding rack, an oil spraying area and a stamping station in sequence along the feeding direction; a conveying unit is provided on the frame and moves back and forth between a picking position and a discharging position along the feeding direction; a first picking unit and a second picking unit are connected to the conveying unit, and when at the picking position, the first picking unit picks up the material on the feeding rack, and the second picking unit picks up the material on the oil spraying area at the same time; when at the discharging position, the material picked up by the first picking unit is placed in the oil spraying area, and the material picked up by the second picking unit is placed in the stamping station at the same time.

[0006] After adopting the above structure, the practical automatic feeding mechanism for water bowl processing has the following advantages compared with the prior art: the first picking unit and the second picking unit synchronously pick up materials from the feeding rack and the oil injection area, and discharge materials in the oil injection area and the stamping station at the same time, and the conveying unit moves back and forth between the picking position and the discharge position to realize the transfer of the picked materials, and finally the materials are stamped and formed at the stamping station. The entire feeding process is automatically completed by machines instead of manual labor, which saves labor and is very efficient.

[0007] As an improvement, the conveying unit includes a rodless cylinder and a slide plate slidably connected to the frame along the feeding direction, and the slide plate is connected to the rodless cylinder; the first pickup unit and the second pickup unit are both arranged on the slide plate. In order to drive the first pickup unit and the second pickup unit to move, the first pickup unit and the second pickup unit can also be connected to a common cylinder respectively. In the present invention, by using the rodless cylinder and the driving structure of the slide plate, not only can the cylinder be saved, but the rodless cylinder can also greatly save the installation space compared with the common cylinder.

[0008] As an improvement, the first picking unit includes a first suction cup assembly and a servo motor connected to the slide in a vertical sliding direction; a threaded hole is provided on the slide, and a screw is connected to the threaded hole; the upper end of the screw is connected to the output end of the shaft of the servo motor, and the lower end of the screw is connected to the first suction cup assembly. When the material placement height on the loading rack is constant, the first suction cup assembly can be controlled by the cylinder to pick up the material, and the first suction cup assembly can be controlled by the structure to pick up the sheet; if the material placement height on the loading rack is not fixed, for example: the material is in a stacked state on the loading rack, and as the upper material is picked up, the height of the lower material is picked up. At this time, it is required that each time the material is picked up from the loading rack, the descending height of the first suction cup assembly should be able to adapt to the change of the height reduction of the material being picked up, and the cylinder-driven suction cup structure cannot meet this requirement because each stroke of the cylinder is fixed. This structure can adapt to the picking requirements of materials placed at different heights on the loading rack.

[0009] Specifically, a plurality of guide holes are provided on the slide plate around the threaded hole, and guide posts are inserted into the guide holes; the upper end of the guide post is connected to a motor mounting seat, a servo motor is mounted on the motor mounting seat, and the lower end of the guide post is connected to the first suction cup assembly. In this structure, since a lead screw is connected between the servo motor mounted on the motor mounting seat and the slide plate, the threaded connection between the lead screw and the threaded hole provides a support structure for the motor mounting seat, ensuring that the guide post connected to the motor mounting seat will not slide in the guide hole of the slide plate when the lead screw does not rotate; only when the servo motor rotates, the lead screw is driven to rotate, and the guide post is driven to slide in the guide hole by the rotation of the lead screw, thereby controlling the first suction cup assembly connected to the lower end of the guide post to perform lifting and lowering movements.

[0010] As an improvement, a through hole is provided on the motor mounting seat, and the screw rod is passed through the through hole and is connected to the output end of the rotating shaft of the servo motor. In this structure, the through hole on the motor mounting seat can provide better support for the screw rod, ensuring that when the servo motor rotates, the end of the screw rod connected to the servo motor will not vibrate, and the connection is more stable.

[0011] Specifically, a height sensor is provided on the frame on one side of the loading rack. The height sensor is electrically connected to the controller and is used to detect the height change of the first suction cup assembly when it is raised or lowered above the loading rack. The controller is electrically connected to the servo motor and is used to control the servo motor to stop or rotate according to the height change of the first suction cup assembly. When the first suction cup assembly is picking up materials on the loading rack, as the upper material is picked up, the height sensor detects that the placement height of the lower layer of the material to be picked up is reduced, and the height sensor sends an electrical signal to the controller. The controller electrical signal controls the number of revolutions of the servo motor, and then controls the height of the first suction cup assembly to descend by rotating the screw in the screw through hole, so as to adapt to the placement height change of the material to be picked up on the loading rack.

[0012] Specifically, at least one fuel injector is connected to the frame around the fuel injection area, the fuel injector is electrically connected to the controller, and the nozzle of the fuel injector is arranged toward the center of the fuel injection area. The fuel injector is used to spray fuel to the material placed in the fuel injection area. After the material is sprayed with fuel, it can play a role in lubrication and cooling in the mold cavity during stamping.

[0013] Specifically, position sensors are also provided on the frames around the injection area, which are electrically connected to the controller and used to detect whether there is material placed in the injection area. When the position sensor detects that there is material placed in the injection area, the position sensor sends an electrical signal to the controller, and the controller sends the electrical signal to control the injector to spray the material.

[0014] Specifically, the second picking unit includes a cylinder and a second suction cup assembly, the cylinder is vertically arranged at the bottom of the slide, and the piston rod output end of the cylinder is connected to the second suction cup assembly. The second picking unit is used to pick up the oil-sprayed sheet from the oil spraying area and place the material picked up from the oil spraying area at the stamping station.

[0015] As an improvement, the loading rack and the stamping station are equally spaced on both sides of the injection area in the horizontal direction, and the horizontal spacing between the first pickup unit and the second pickup unit on the slide is the same as the horizontal spacing between the injection area and the loading rack. In this structure, when the first pickup unit and the second pickup unit are fixedly connected to the slide in the horizontal direction, since the horizontal spacing between the loading rack and the injection area, between the injection area and the stamping station, and between the first pickup unit and the second pickup unit are the same, the rodless cylinder can push the first pickup unit and the second pickup unit to the top of the injection area and the stamping station respectively at the same time with one output.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] Embodiment 1:

[0024] like Figures 1 to 4 As shown: This embodiment is a preferred embodiment of the present invention. In this embodiment, the automatic feeding mechanism for processing water bowls includes a frame 1, which is provided with a feeding rack 3, an oil spraying area 4 and a stamping station 5 in sequence along the feeding direction; the frame 1 is provided with a conveying unit 2 which moves back and forth between a picking position and a discharging position along the feeding direction; the conveying unit 2 is connected to a first picking unit 6 and a second picking unit 7. When at the picking position, the first picking unit 6 picks up the material on the feeding rack 3, and the second picking unit 7 picks up the material on the oil spraying area 4 at the same time; when at the discharging position, the material picked up by the first picking unit 6 is placed in the oil spraying area 4, and the material picked up by the second picking unit 7 is placed in the stamping station 5 at the same time.

[0025] After adopting the above structure, the practical automatic feeding mechanism for water bowl processing has the following advantages compared with the prior art: the first picking unit and the second picking unit synchronously pick up materials from the feeding rack and the oil injection area, and discharge materials in the oil injection area and the stamping station at the same time, and the conveying unit moves back and forth between the picking position and the discharge position to realize the transfer of the picked materials, and finally the materials are stamped and formed at the stamping station. The entire feeding process is automatically completed by machines instead of manual labor, which saves labor and is very efficient.

[0026] like Figures 1 to 4As shown: the conveying unit 2 includes a rodless cylinder 21 and a slide plate 22 slidably connected to the frame 1 along the feeding direction, and the slide plate 22 is connected to the rodless cylinder 21; the first pickup unit and the second pickup unit are both arranged on the slide plate 22. In order to drive the first pickup unit and the second pickup unit to move, the first pickup unit and the second pickup unit can also be connected to a common cylinder respectively. In the present invention, compared with the driving structure of the rodless cylinder and the slide plate respectively controlled by two common cylinders, not only can the cylinder be saved, but also the rodless cylinder can greatly save the installation space compared with the common cylinder.

[0027] like Figure 1 As shown: the first picking unit 6 includes a first suction cup assembly 61 and a servo motor 62 slidably connected to the slide plate 22 along the vertical direction; a threaded hole 221 is opened on the slide plate 22, and a screw rod 222 is threadedly connected to the inner thread of the threaded hole 221; the upper end of the screw rod 222 is transmission-connected to the output end of the rotating shaft of the servo motor 62, and the lower end of the screw rod 222 is rotationally connected to the first suction cup assembly 61. When the material placement height on the loading rack is fixed, the first suction cup assembly can be controlled by the cylinder to pick up the material, or the first suction cup assembly can be controlled by this structure to pick up the material sheet; if the material placement height on the loading rack is not fixed, for example: the material is in a stacked state on the loading rack, and as the upper material is picked up, the height at which the lower material is picked up decreases accordingly. At this time, it is required that each time the material is picked up from the loading rack, the descending height of the first suction cup assembly must be able to adapt to the change in the height at which the material is picked up. The cylinder-driven suction cup structure cannot meet this requirement because each stroke of the cylinder is fixed. This structure can adapt to the picking requirements of materials placed at different heights on the loading rack.

[0028] Specifically, a plurality of guide holes 223 are provided on the slide plate 22 around the threaded hole 221, and a guide post 224 is inserted into the guide hole 223; the upper end of the guide post 224 is connected to the motor mounting seat 8, and the servo motor 62 is installed on the motor mounting seat 8, and the lower end of the guide post 224 is connected to the first suction cup assembly 61. In this structure, since a lead screw is connected between the servo motor installed on the motor mounting seat and the slide plate, the threaded connection between the lead screw and the threaded hole provides a support structure for the motor mounting seat, ensuring that the guide post connected to the motor mounting seat will not slide in the guide hole of the slide plate when the lead screw does not rotate; only when the servo motor rotates, the lead screw is driven to rotate, and the guide post is driven to slide in the guide hole by the rotation of the lead screw, thereby controlling the first suction cup assembly connected to the lower end of the guide post to perform lifting and lowering movements.

[0029] Furthermore, if Figure 1As shown: a through hole 81 is provided on the motor mounting seat 8, and the screw rod 222 is passed through the through hole 81 and is drivingly connected to the output end of the rotating shaft of the servo motor 62. In this structure, the through hole on the motor mounting seat can provide better support for the screw rod, ensuring that when the servo motor rotates, the end of the screw rod connected to the servo motor will not vibrate, and the connection is more stable.

[0030] like Figure 1 and Figure 2 As shown: a height sensor 11 is provided on the frame 1 on one side of the loading rack 3. The height sensor 11 is electrically connected to the controller 9 and is used to detect the height change of the first suction cup assembly 61 when it is lifted above the loading rack 3; the controller 9 is electrically connected to the servo motor 62 and is used to control the servo motor 62 to stop or rotate according to the height change of the first suction cup assembly 61. When the first suction cup assembly is picking up materials on the loading rack, as the upper layer of materials is picked up, the height sensor detects that the placement height of the lower layer of materials to be picked up is reduced, and the height sensor sends an electrical signal to the controller. The controller electrical signal controls the number of turns of the servo motor, and then controls the height of the first suction cup assembly to be lowered by rotating the screw in the screw through hole, so as to adapt to the placement height change of the materials to be picked up on the loading rack.

[0031] like Figure 3 and Figure 4 As shown: at least one fuel injector 41 is connected to the frame 1 around the fuel injection area 4, usually four fuel injectors 41 are respectively connected to the frame 1 around the fuel injection area 4, the fuel injector 41 is electrically connected to the controller 9, and the nozzle of the fuel injector 41 is arranged toward the center of the fuel injection area 4. The fuel injector is used to spray fuel to the material placed in the fuel injection area, and after the material is sprayed with fuel, it can play a role in lubrication and cooling in the mold cavity during stamping.

[0032] Furthermore, if Figure 3 and Figure 4 As shown: position sensors 12 are also provided on the frame 1 around the injection area 4, and the position sensors 12 are electrically connected to the controller 9 and are used to detect whether there is material placed in the injection area 4. When the position sensor detects that there is material placed in the injection area, the position sensor sends an electrical signal to the controller, and the controller sends an electrical signal to control the injector to spray the material.

[0033] like Figure 3 and Figure 4 As shown, the second picking unit 7 includes a cylinder 71 and a second suction cup assembly 72. The cylinder 71 is vertically arranged at the bottom of the slide plate 22, and the piston rod output end of the cylinder 71 is connected to the second suction cup assembly 72. The second picking unit is used to pick up the oil-sprayed sheet from the oil spraying area and place the material picked up in the oil spraying area at the stamping station.

[0034] like Figure 1As shown: the loading rack 3 and the punching station 5 are equally spaced on both sides of the injection area 4 in the horizontal direction; the horizontal spacing between the first pickup unit and the second pickup unit on the slide 22 is the same as the horizontal spacing between the injection area 4 and the loading rack 3. In this structure, when the first pickup unit and the second pickup unit are fixedly connected to the slide in the horizontal direction, since the horizontal spacing between the loading rack and the injection area, between the injection area and the punching station, and between the first pickup unit and the second pickup unit are the same, the rodless cylinder can push the first pickup unit and the second pickup unit to the top of the injection area and the punching station respectively at the same time with one output.

[0035] Embodiment 2:

[0036] This embodiment is another implementation of the present invention, and is different from the first embodiment in that the conveying unit 2 includes two stroke cylinders (not shown in the figure) arranged in parallel on the frame 1, and the piston rod output ends of the two stroke cylinders are respectively connected to the first pickup unit 6 and the second pickup unit 7. The first pickup unit 6 and the second pickup unit 7 are both composed of ordinary cylinders and suction cups, and the two cylinders are vertically connected to the piston rod output ends of the two stroke cylinders. The two stroke cylinders are used to control the movement of the first pickup unit and the second pickup unit respectively, and complete the transfer of the sheet picked up from the loading rack to the injection area, and the transfer of the sheet picked up from the injection area that has been sprayed with oil to the stamping station. The two transfers are completed in the two cylinder activities. Compared with the technical solution in which a rodless cylinder cooperates with a slide to drive the first picking unit 6 and the second picking unit 7 to move horizontally synchronously, in this structure, the first picking unit adopts a picking structure of a cylinder-driven suction cup. Although this structure can only be adapted to the picking operation when the material sheets on the loading rack are placed at a certain height, it cannot meet the situation where the material sheets on the loading rack are placed at an uncertain height. However, compared with the structure in Example 1, in this embodiment, the structure of the first picking unit is simpler and easier to implement.

[0037] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
