Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, specifically a mechanism for feeding trays. Background Technology

[0002] In the material supply process, especially in the loading process using trays as material carriers, it is crucial to ensure that trays can be reliably, accurately, and quickly loaded to designated locations. However, existing tray loading processes often rely on manual operation, requiring workers to frequently move the trays to the designated positions. In actual production, this manual loading significantly impacts production efficiency. Therefore, there is an urgent need to develop an automated loading mechanism that can improve the efficiency of tray loading. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a mechanism for feeding trays, which reliably transports the trays from the feeding position to the discharging position and reliably pushes them upwards layer by layer, ensuring efficient tray feeding.

[0004] A mechanism for loading trays, characterized in that it comprises:

[0005] The vertical frame has feeding and discharging positions along its length.

[0006] The conveyor belt includes two spaced conveyor belts. One end of the two conveyor belts is connected by a driven roller assembly and the other end is connected by a driving roller assembly along their length. The upper surfaces of the two conveyor belts are used to support and place the tray and drive the tray from the loading position to the unloading position.

[0007] The power source for the conveyor belt is used to drive the conveyor belt to move horizontally.

[0008] And a lifting module, which includes a servo motor, a lifting plate, and a lead screw module, wherein the servo motor drives the lead screw module to drive the lifting plate to lift and lower.

[0009] The vertical frame is used for loading the stacked trays. The stacked trays are supported on both sides of the width direction by the corresponding conveyor belt positions. The output end of the conveyor belt power source is connected to the input end of the active roller assembly. In the non-working state, the lifting plate is located below the upper surface of the conveyor belt and in the discharge position area. In the working state, the lifting plate is lifted a set distance by a servo motor, thereby driving the trays to be lifted and loaded step by step.

[0010] Its further features are:

[0011] The lifting module also includes a fixed plate, a lower plate, and several connecting columns. The fixed plate is fixed below the material discharge position of the vertical frame. The lower plate is located below the fixed plate and is equipped with a servo motor. The output end of the servo motor is connected to the lead screw. The lead screw is threaded to the lead screw nut on the fixed plate. The top of the lead screw is positioned and connected to the lifting plate through a bearing. The lifting plate is fixed to the lower plate below through several connecting columns around its perimeter. The connecting columns pass through corresponding linear bearings on the fixed plate. The servo motor rotates in a stepping motion, driving the lifting plate to rise step by step in the height direction.

[0012] The power source for the output belt includes a drive motor and a first bevel gear. The drive motor is fixedly mounted on the lower outer end of the vertical frame relative to the discharge position. The output end of the drive motor is fixedly connected to the first bevel gear. The driving roller assembly includes a first roller shaft, a second bevel gear, and sprockets at both ends. The driven roller assembly includes a second roller shaft and sprockets at both ends. The second bevel gear is sleeved on the first roller shaft at a position corresponding to the first bevel gear. The first bevel gear and the second bevel gear are meshed and connected. Corresponding sprockets are fixedly mounted at both ends of the first roller shaft and the second roller shaft. The synchronous belt is a chain, and the sprockets are meshed and connected to the chains on the corresponding sides and at the corresponding ends.

[0013] The chains on both sides pass through the corresponding notches in the bottom plate of the vertical frame, so that the bottom of the upper chain is supported.

[0014] The bottom plate of the vertical frame is provided with an avoidance notch corresponding to the discharge position, and the lifting plate completes the step lifting operation of the tray through the avoidance notch;

[0015] A photoelectric sensor is also provided on the bottom plate of the feeding position. The photoelectric sensor is used to sense whether there is a tray at the feeding position.

[0016] The base plate is equipped with tray blocking blocks in the areas corresponding to the infeed and discharge positions. The bottom of the tray blocking blocks is driven by a lifting cylinder. In the initial state, the tray blocking blocks bulge upwards. When the photoelectric sensor detects that the tray has been loaded into position, the lifting cylinder drives the tray blocking blocks to descend. The chains on both sides drive the stacked trays to move towards the discharge position until they are fully in place.

[0017] The upper layer of the vertical frame is equipped with partitions corresponding to the feeding and discharging positions. A baffle plate is provided on the side of the partition plate facing the discharging position. The baffle plate is connected to a horizontal drive cylinder. When the tray rises, the horizontal drive cylinder drives the baffle plate to block one side of the tray, ensuring that the tray rises stably.

[0018] With this invention, before starting the equipment, the operator manually places the tray filled with material onto the conveyor belt at the feeding position. After the equipment starts, the power source of the conveyor belt drives the conveyor belt to move horizontally, driving the tray to move forward in the specified direction to the discharge position. After the tray reaches the discharge position, the servo motor drives the lifting plate to rise step by step until the tray is completely discharged. Then, the next round of tray feeding continues. This ensures that the tray is reliably transported from the feeding position to the discharge position and reliably pushed upward layer by layer, ensuring the feeding efficiency of the tray.

[0027] The interior of the vertical frame 10 is provided with a feeding position 101 and a discharging position 102 along the length direction;

[0028] The conveyor belt 20 includes two conveyor belts arranged at intervals. One end of the two conveyor belts is connected by a driven roller assembly 50 and the other end is connected by a driving roller assembly 60 in the longitudinal direction. The upper surfaces of the two conveyor belts are used to support and place the tray 70 and drive the tray 70 from the loading position 101 to the unloading position 102.

[0029] The conveyor belt power source 30 is used to drive the conveyor belt to move horizontally.

[0030] The lifting module 40 includes a servo motor 41, a lifting plate 42, and a lead screw module. The lead screw module includes a lead screw 43 and a lead screw nut 44. The servo motor 41 drives the lead screw module to drive the lifting plate 42 to lift and lower.

[0031] The loading position 101 of the vertical frame 10 is used for loading the stacked trays 70. The two sides of the stacked trays 70 in the width direction are respectively supported by the corresponding conveyor belt positions. The output end of the conveyor belt power source 30 is connected to the input end of the active roller assembly 60. In the non-working state, the lifting plate 42 is located below the upper surface of the conveyor belt and in the discharge position 102 area. In the working state, the lifting plate 42 is lifted by a servo motor 41 step by step to a set distance, thereby driving the trays 70 to step by step to load the trays.

[0032] In a specific embodiment, the lifting module 40 also includes a fixed plate 45, a lower plate 46, and four connecting columns 47. The fixed plate 45 is fixed below the material discharge position 102 of the vertical frame 10. The lower plate 46 is located below the fixed plate 45. A servo motor 41 is fixedly mounted on the lower plate 46. The output end of the servo motor 41 is connected to a lead screw 43. The lead screw 43 is threadedly connected to a lead screw nut 44 on the fixed plate 45. The top of the lead screw 43 is positioned and connected to the lifting plate 42 through a bearing. The lifting plate 42 is fixed to the lower plate 46 below through the connecting columns 47 around it. The connecting columns 47 pass through the corresponding linear bearings on the fixed plate 45. The servo motor 41 rotates stepwise, driving the lifting plate 42 to rise stepwise in the height direction.

[0033] The output belt power source 30 includes a drive motor 31 and a first bevel gear 32. The drive motor 31 is fixedly mounted on the lower part of the outer end of the vertical frame 10 relative to the discharge position 102. The output end of the drive motor 31 is fixedly connected to the first bevel gear 32. The active roller assembly 60 includes a first roller shaft 61, a second bevel gear 62, and sprockets at both ends. The driven roller assembly 50 includes a second roller shaft 51 and sprockets at both ends. The second bevel gear 62 is sleeved at the position of the first roller shaft 61 corresponding to the position of the first bevel gear 32. The first bevel gear 32 and the second bevel gear 63 are meshed and connected. The two ends of the first roller shaft 61 and the second roller shaft 51 are respectively fixed with corresponding sprockets. The synchronous belt is a chain 21. The sprockets are meshed and connected to the chain 21 on the corresponding side and the corresponding end.

[0034] The chains 21 on both sides pass through the corresponding notches in the bottom plate of the vertical frame, so that the bottom of the upper chain 21 is supported.

[0035] The bottom plate 11 of the vertical frame 10 is provided with an avoidance notch 103 corresponding to the discharge position 102. The lifting plate 52 completes the step lifting operation of the tray 70 through the avoidance notch 103.

[0036] A photoelectric sensor 80 is also provided on the base plate 11 of the feeding position 101. The photoelectric sensor 80 is used to sense whether there is a tray 70 at the feeding position 101.

[0037] The base plate 11 is provided with a tray blocking block 90 in the area corresponding to the feeding position 101 and the discharging position 102. The bottom of the tray blocking block 90 is driven by the lifting cylinder 91. In the initial state, the tray blocking block 90 protrudes upward. When the photoelectric sensor 80 senses that the tray 70 has been fed into place, the lifting cylinder 91 drives the tray blocking block 90 to descend. The chains 21 on both sides drive the stacked trays 70 to move towards the discharging position until they are fully in place.

[0038] The upper layer of the vertical frame 10 is provided with a partition 12 corresponding to the feeding position 101 and the discharging position 102. A baffle plate 13 is provided on the side of the partition 12 facing the discharging position 102. The baffle plate 13 is connected to a horizontal drive cylinder 14. When the tray 70 rises, the horizontal drive cylinder 14 drives the baffle plate 13 to block one side of the tray 70, ensuring that the tray 70 rises stably.

[0039] Compared to the traditional tray loading method, this device takes a unique approach by introducing an advanced automated stepping feed mechanism. The traditional loading process often relies on manual operation, requiring workers to frequently move the tray to the designated position. In contrast, the automated stepping feed system in this design, with the help of a precise motor drive and intelligent control system, accurately and efficiently propels the tray forward, which not only significantly reduces the company's labor costs but also greatly reduces the labor intensity of workers.
