Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a tray supply and full-load unloading device. Background Art

[0002] Trays play an important role in modern manufacturing and logistics industries. They are standardized containers used for storing and transporting parts, components, or materials. They are usually designed with unified dimensions and shapes, facilitating efficient processing in automated production lines and warehousing systems. Trays are made of various materials, including plastics, metals, and composite materials, and can adapt to different usage environments and requirements. During the manufacturing process, trays are widely used to transfer parts from one process to another, ensuring the continuity and efficiency of the production process. They can not only protect parts from damage but also improve the operation efficiency of the production line through standardized management. Trays are usually used in conjunction with automated equipment, such as robotic arms, conveyor belts, and tray supply systems, to achieve precise positioning and rapid transfer of parts.

[0003] In the prior art, the supply of empty trays and the unloading of full trays are usually carried out by two separate devices. For example, a tray transfer mechanism with the publication number CN214933971U discloses the transfer of full trays to achieve material supply operations to improve automated production efficiency. However, using two transfer devices requires waiting for the full tray to be removed before the empty tray can be moved to the designated position to load workpieces, which has a certain impact on the workpiece unloading efficiency of the entire line and is not conducive to the spatial optimization layout of the entire line. Summary of the Utility Model

[0004] In view of this, the utility model provides a tray supply and full-load unloading device. By setting a lifting mechanism, the supply of empty trays and the unloading of full trays are carried out respectively. Especially when the full tray descends, the transfer mechanism can transfer the empty tray from the loading station to above the unloading station, thus achieving rapid connection, effectively shortening the waiting time for tray replacement, and further improving the tray loading efficiency of the production line.

[0005] The technical solution of the utility model is realized as follows: The utility model provides a tray supply and full-load unloading device, including a workbench, a lifting mechanism, a transmission mechanism, and a transfer mechanism. Among them,

[0034] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] As Figures 1-5 shown, the tray supply and full-load unloading device of the present utility model includes a workbench 1, a lifting mechanism 2, a transmission mechanism 3 and a transfer mechanism 4.

[0036] A transfer surface, a loading station and an unloading station are provided on the workbench 1. Both the loading station and the unloading station extend to the transfer surface. The workbench 1 is in an overall cabinet shape, and its top surface is the transfer surface. At the same time, the internal space is vertically divided into two parts, which are used as the loading station and the unloading station respectively. Among them, the tray in the loading station is an empty tray, which can move to the transfer surface of the workbench 1 to form a preparatory replacement tray. Except for the top tray, the trays on the unloading station are all full-load trays. When the tray on the unloading station is filled with workpieces, it will move down into the workbench 1. At this time, the preparatory replacement tray can move to the unloading station when the full-load tray moves down, for the workpieces to be stacked.

[0037] The number of the lifting mechanisms 2 is two, and they are respectively arranged at the loading station and the unloading station. The lifting mechanism 2 includes a movable plate 21, and the movable plate 21 can move vertically at the loading station and the unloading station to drive the tray to enter and leave the transfer surface.

[0038] The provided lifting mechanism 2 can drive the tray to move vertically at the loading station and the unloading station, so that the empty tray enters the transfer surface, or drives the full tray away from the transfer surface. During the operation, in order to reduce the number of reciprocating movements of the lifting mechanism 2, the trays can be stacked directly for supply or unloading. Specifically, during the supply process, the lifting mechanism 2 raises the topmost tray of the stacked trays into the transfer surface. During the unloading process, the top full tray descends into the interior of the workbench 1. The movable plate 21 is the component that supports the tray for lifting and lowering actions.

[0039] The number of the transfer mechanisms 3 is two, and both are arranged on the workbench 1. The two transfer mechanisms 3 respectively extend into the loading station and the unloading station to send the trays into the loading station and out of the unloading station.

[0040] When the lifting mechanism 2 supplies and unloads the trays through lifting, the empty trays on its movable plate 21 are used up, or the stacked full trays reach the set number of layers, the lifting mechanism 2 can lift the empty trays from the transfer mechanism 3, or place the full trays on the transfer mechanism 3, and the transfer mechanism 3 sends the trays into the loading station or out of the unloading station.

[0041] The transfer mechanism 4 is arranged on the transfer surface. The transfer mechanism 4 includes a grasping part 41. The grasping part 41 is movably arranged on the workbench 1 and is used to grasp the tray on the transfer surface to send the tray at the loading station into the unloading station. The transfer mechanism 4 is used to suck the empty tray at the loading station through the negative pressure of the grasping part 41 on the transfer surface and horizontally transfer it to the unloading station.

[0042] In this embodiment, the unloading station is the workpiece unloading and loading station of the production line. When the tray for loading at the unloading station is full, the transfer mechanism 4 can transfer the empty tray towards the unloading station. During the transfer, the full tray descends. It should be noted that when the workpiece is loaded into the tray, the transfer mechanism 4 resets to the loading station to grab and transfer the empty tray in the first time, and also avoids affecting the tray loading operation.

[0043] For the lifting mechanism 2, it further includes a linear driving part 22 and a sliding seat 23. The linear driving part 22 is fixed on the workbench 1. The sliding seat 23 is arranged on the linear driving part 22 and is in transmission connection with the linear driving part 22 to make the sliding seat 23 lift on the workbench 1. The movable plate 21 is fixed on the sliding seat 23.

[0044] The linear drive part 22 therein can directly use a linear module, specifically a motor-driven lead screw, to drive the carriage 23 threadedly connected to the lead screw to move up and down. The carriage 23 is connected to the movable plate 21, so that the movable plate 21 moves synchronously. The movable plate 21 mainly supports the tray, enabling the tray to move vertically. The surface of the movable plate 21 in contact with the tray is parallel to the ground, and the movable plate 21 is centrally arranged on the moving path of the tray.

[0045] As a preferred embodiment, the transmission mechanism 3 includes two conveyor belts 31. Both of the two conveyor belts 31 are arranged on the workbench 1, and a tray placing gap is arranged between the two conveyor belts 31. The tray placing gap is used to accommodate the movable plate 21.

[0046] The conveyable lengths of the two conveyor belts 31 need to be greater than the length of the tray. At the same time, the width of the tray placing gap needs to be greater than the width of the movable plate 21 and less than the width of the tray, so that the tray can move through the movable plate 21 in the tray placing gap and be placed on the two conveyor belts 31, or the tray on the two conveyor belts 31 can be lifted upward.

[0047] In addition, the transmission mechanism 3 further includes a mounting seat 32, a driving shaft 33 and a driving motor 34. The mounting seat 32 is fixed on the workbench 1 and is arranged in a U shape. The two conveyor belts 31 are respectively arranged on two side walls inside the mounting seat 32. The driving shaft 33 is arranged in the mounting seat 32 and is in transmission connection with the two conveyor belts 31. The driving motor 34 is fixed outside the mounting seat 32 and is in transmission connection with the driving shaft 33.

[0048] The mounting seat 32 is directly fixed to the inside of the workbench 1 by bolts. One side of its U-shaped groove faces upward, and several symmetrically arranged belt support wheels are installed in the mounting seat 32. The two conveyor belts 31 are respectively arranged on the support wheels on the corresponding sides. The tray placing gap is between the two sides of the support wheels. The movable plate 21 can move downward between the two sides of the support wheels to place the tray on the two conveyor belts 31, or move upward between the two support wheels to lift the tray on the two conveyor belts 31 upward. The arranged driving shaft 33 is fixed to two opposite support wheels away from the movable plate 21, so as to realize the transmission between the support wheels and the conveyor belts 31. Specifically, the driving motor 34 is fixed to the bottom of the mounting seat 32, and a sprocket is installed at the output end of the driving motor 34 and the outside of the driving shaft 33, and the driving motor 34 and the driving shaft 33 are in transmission connection through a chain.

[0049] As a preferred embodiment, a storage mechanism 5 is also provided. The storage mechanism 5 is oppositely arranged outside the workbench 1, and one end thereof is butted against the transmission mechanism 3. The other end of the storage mechanism 5 is used for putting in and taking out the tray.

[0050] Since the transmission mechanism 3 is arranged inside the workbench 1 and its length is relatively limited, it cannot be directly docked with the conveyor line or a large number of trays can be stored. The provided storage mechanism 5 can be docked with the transmission mechanism 3 to temporarily store the trays that have not entered or exited the workbench 1. In addition to storage, it can also be directly docked with an external conveyor line or production line, so as to recycle the trays, thereby further improving the automation degree of the production line.

[0051] Specifically, the storage mechanism 5 includes a structural frame 51 and a conveyor belt 52. The structural frame 51 is arranged outside the workbench 1, and the conveyor belt 52 is arranged on the structural frame 51. The conveyor belt 52 is used for transporting trays.

[0052] The structural frame 51 is directly arranged on the ground. The width of the conveyor belt 52 is preferably the sum of the widths of the two conveyor belts 31 and the width of the tray placement gap. There is a small gap between the conveyor belt 52 and the two conveyor belts 31. After the tray passes through this gap, it is transferred from the conveyor belt 31 to the conveyor belt 52, realizing the docking of the conveyor belt 31 and the conveyor belt 52 during the tray transportation process. For the storage of trays, the number of trays that can be accommodated can be directly determined by the length of the conveyor belt 52.

[0053] In this embodiment, two through openings are formed on the workbench 1. Both of the two through openings are located on the transfer surface and respectively correspond to the loading station and the unloading station.

[0054] The length and width of the provided through openings are both larger than the length and width of the tray, so that during the lifting process of the movable plate 21, the tray can pass through the through opening to enter or leave the moving surface, realizing the transfer of the tray from the inside of the workbench 1 to the top, and then cooperating with the transfer mechanism 4 to perform the station transfer of the tray.

[0055] As a preferred embodiment, a positioning baffle 6 is also provided. The positioning baffle 6 is fixed in the through opening corresponding to the unloading station. The positioning baffle 6 is used to limit the position of the tray entering the unloading station.

[0056] The positioning baffle 6 is specifically a short tube formed by bending a plate member with a sloped inner opening. It is arranged in the through opening corresponding to the unloading station. The top of the positioning baffle 6 is bent outward from the through opening and is provided with an oval hole. The positioning baffle 6 is fixed to the workbench 1 through a bolt and the oval hole. When the tray is placed in the positioning baffle 6, if the tray is slightly offset, it will be corrected by the inner slope of the positioning baffle 6, thereby greatly reducing the error after it is placed, and avoiding the situation that when a mechanical arm or other equipment places a workpiece into the tray, it cannot align with the notch on the tray, resulting in difficulty in arranging the workpieces into the tray.

[0057] In this embodiment, the transfer mechanism 4 further includes a lifting assembly 42. The lifting assembly 42 is slidably disposed on the workbench 1, and the grasping portion 41 is disposed on the lifting assembly 42. The lifting assembly 42 is used to drive the grasping portion 41 to move toward and away from the workbench 1.

[0058] Specifically, the transfer mechanism 4 further includes a rodless cylinder and a slide rail disposed on the workbench 1. The rodless cylinder is fixed on the transfer surface of the workbench 1. One end of the lifting assembly 42 is connected to the rodless cylinder, and the other end is slidably disposed on the slide rail. The rodless cylinder drives the lifting assembly 42 to perform linear movement, so as to complete reciprocating movement between the loading station and the unloading station on the transfer surface. The grasping portion 41 contacts or leaves the tray through the lifting movement of the lifting assembly 42.

[0059] The lifting assembly 42 can directly select a cylinder as the driving part and set corresponding connecting parts and guide rods to realize the guiding of the grasping portion 41. On the transfer mechanism 4, a total of four grasping portions 41 are provided, and the four grasping portions 41 cooperate with each other to complete the grasping and transfer operation of the tray.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
