Description

Technical Field

[0001] The utility model relates to the technical field of automatic loading and unloading, in particular to a loading system capable of automatically separating stacked full trays, loading materials, and collecting empty trays. Background Art

[0002] At present, high-precision small parts in the market are usually placed in trays for storage, and multiple trays are stacked and assembled during transportation to ensure the integrity of the parts. Therefore, when inspecting the parts, the stacked trays need to be separated one by one before loading.

[0003] In the prior art, the method of separating stacked trays filled with parts is mainly to use a manipulator to remove each tray from top to bottom one by one for material separation, and then use manual labor or a manipulator to transport the separated trays to the designated loading position.

[0004] In the existing tray separation and loading method, on the one hand, after all the trays in the previous stack are separated, the next stack of trays filled with parts needs to be stacked at the separation station. During the process of replacing the next stack of trays, the manipulator is in a shutdown state, resulting in a long waiting time and low separation efficiency, which affects the overall production efficiency. On the other hand, installing a manipulator requires a large amount of space, which is not conducive to the compact design of the equipment and has a high cost. Moreover, the stacked full trays are separated by the manipulator from top to bottom, and then the separated trays are transported to the designated loading position by manual labor or a manipulator, with cumbersome actions and complex program control, which affects the operation stability. Summary of the Invention

[0005] The utility model provides an automatic tray separation and loading device, which can solve the problems in the prior art that the stacked trays are separated one by one from top to bottom, with low separation and loading efficiency, a large number of required manipulators, large occupied space, and high cost.

[0016] The lifting driving component is integrated with the full material tray support plate, and the lifting output end of the lifting driving component avoids the full material tray support plate.

[0017] The first support frame body is in the shape of a rectangular frame, and a plurality of the first chuck assemblies are respectively arranged at the four corner parts of the first support frame body.

[0047] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0048] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0049] Refer to Figure 1 , a tray automatic disk-splitting and feeding device in this embodiment includes a conveying line 1000 and a full tray disk-splitting mechanism 2000, a feeding mechanism 3000, and a tray collecting mechanism 4000 arranged in sequence along the conveying direction of the conveying line 1000.

[0050] Taking the perspective as shown in Figure 1 as an example, the conveying line 1000 extends left and right, the full tray disk-splitting mechanism 2000, the feeding mechanism 3000, and the tray collecting mechanism 4000 are arranged in sequence from left to right. A partition is provided between the full tray disk-splitting mechanism 2000 and the feeding mechanism 3000, and a partition is provided between the feeding mechanism 3000 and the tray collecting mechanism 4000. The stacked full trays 1 are placed on the full tray disk-splitting mechanism 2000 for disk splitting, and the separated single full trays 1 are conveyed by the conveying line 1000 to the intermediate feeding mechanism 3000 for feeding. After the materials are taken from the feeding mechanism 3000, the empty trays 2 are then conveyed by the conveying line 1000 to the tray collecting mechanism 4000 for empty tray collection.

[0051] Refer to Figures 2 to 7, the full - material tray separating mechanism 2000 includes a first support frame 2100. The first support frame 2100 encloses a full - material tray accommodating space for accommodating stacked full - material trays 1. The first support frame 2100 includes a first support frame body 2110.

[0052] The full - material tray separating mechanism 2000 includes a first lifting drive assembly 2200. A full - material tray support plate 2300 is provided on the lifting output end of the first lifting drive assembly 2200.

[0053] The full - material tray separating mechanism 2000 includes a plurality of first chuck assemblies 2400. The plurality of first chuck assemblies 2400 are arranged on the first support frame body 2110 along the extending direction of the first support frame body 2110. The plurality of first chuck assemblies 2400 act simultaneously to jointly support or release the full - material tray 1.

[0054] Each first chuck assembly 2400 includes a chuck part 2410 and a chuck drive part. The chuck drive part is at least used to drive the chuck part 2410 to move towards the inside of the full - material tray accommodating space, so as to separate any two adjacent full - material trays 1 in the stacked full - material trays 1 and support the full - material tray 1 located above the chuck part 2410.

[0055] Specifically, since the circumferential side surface of the tray (including the full - material tray 1 and the empty tray 2, the full - material tray 1 and the empty tray 2 have the same structure, only the difference between being full - material and being empty - material) has a certain slope, after being stacked in a stack, there is a certain gap in the up - down direction between the bottom edge flanging 11 of two adjacent full - material trays 1, which provides space for the chuck part 2410 to support the full - material tray 1. The chuck part 2410 specifically supports the bottom edge flanging 11 of the full - material tray 1, as Figure 6 shown.

[0056] The first lifting drive assembly 2200 is configured to drive the full material tray 1 located below the chuck assembly 2410 to move downward through the full material tray support plate 2300 until the full material tray 1 below the chuck assembly 2410 lands on the conveyor line 1000 when the chuck assembly 2410 separates any two adjacent full material trays 1. That is, when the chuck assembly 2410 separates any two adjacent full material trays 1, the full material tray 1 above the chuck assembly 2410 is jointly supported by a plurality of first chuck assemblies 2400, and the full material tray 1 below the chuck assembly 2410 remains on the full material tray support plate 2300 and is driven to move downward by the first lifting drive assembly 2200 until the full material tray 1 on the full material tray support plate 2300 lands on the conveyor line 1000 and is conveyed by the conveyor line 1000 to the position of the loading mechanism 3000. That is, the height position of the conveyor line 1000 is lower than that of the full material tray support plate 2300 carrying the full material tray 1. The full material tray support plate 2300 drives the full material tray support plate 2300 carrying the full material tray 1 to move downward so that the full material tray 1 can land on the conveyor line 1000, and the full material tray support plate 2300 continues to move downward to disengage from the full material tray 1 that has landed on the conveyor line 1000.

[0057] The loading mechanism 3000 includes a second lifting drive assembly 3100. A loading tray support plate 3200 is provided on the lifting output end of the second lifting drive assembly 3100. The second lifting drive assembly 3100 is configured to drive the full material tray 1 to move upward to the loading position through the loading tray support plate 3200 when the full material tray 1 that has landed on the conveyor line 1000 reaches the loading tray support plate 3200. That is, in the initial state, the height position of the loading tray support plate 3200 is lower than that of the conveyor line 1000. When the conveyor line 1000 conveys the full material tray 1 above the loading tray support plate 3200, the second lifting drive assembly 3100 acts, and the loading tray support plate 3200 moves upward until it jacks up and supports the full material tray 1 to disengage from the conveyor line 1000 and reaches the loading position, waiting for the parts on the tray to be taken and loaded.

[0058] The tray collecting mechanism 4000 is configured to collect the empty trays 2 after the loading on the conveyor line 1000 is completed. That is, after all the parts on the full material tray 1 on the loading tray support plate 3200 are taken away, the empty tray 2 temporarily remains on the loading tray support plate 3200. Then the second lifting drive assembly 3100 acts, and the loading tray support plate 3200 drives the empty tray 2 to move downward until the empty tray 2 lands on the conveyor line 1000 and disengages from the loading tray support plate 3200. The conveyor line 1000 conveys the empty tray 2 to the tray collecting mechanism 4000 to collect the empty trays 2 uniformly.

[0059] Then, the automatic tray separation and feeding system of this embodiment can realize the automatic separation of stacked full trays 1 from bottom to top, and the automatic conveying to the feeding position after separation. After picking up the trays, they are automatically conveyed to the tray collection position for empty tray collection, greatly improving the tray separation and feeding efficiency. The conveyance from the tray separation position to the feeding position and from the feeding position to the tray collection position is carried out by the conveyor line 1000, without the need to configure a manipulator. The action program is simple, the operation is stable, the occupied space is small, and it is beneficial to reduce costs.

[0060] Since the first chuck assembly 2400 of the full tray separation mechanism 2000 can separate any two trays and support the upper tray above the chuck component 2410, and at the same time, the first lifting drive assembly 2200 drives the full tray 1 above the chuck component 2410 to move downward, realizing the separation of the lower full tray 1 and the upper full tray 1. The staff can replenish the trays in the accommodation space of the full tray at any time, and the tray replenishment process does not affect the tray separation action of the full tray separation mechanism 2000, with high separation efficiency.

[0061] Before separating the bottom tray of the stacked full trays 1 placed in the accommodation space of the full tray, the stacked full trays 1 are supported on multiple first chuck assemblies 2400. At this time, the chuck component 2410 is in the support position extending into the accommodation space of the full tray. Taking the example of separating one full tray 1 from the bottom each time, when tray separation is required, the first lifting drive assembly 2200 drives the full tray support plate 2300 to move up to the receiving position. The chuck component 2410 moves out of the accommodation space of the full tray to release the full tray 1, causing the entire stack of full trays to move down by the height of one full tray 1 and land on the full tray support plate 2300 as a whole. Then, the chuck component 2410 moves back into the accommodation space of the full tray to separate the bottommost full tray 1 from the second bottommost full tray 1 and support it at the bottom of the second bottommost full tray 1, thereby supporting the remaining full trays 1 in the accommodation space of the full tray. The original bottommost full tray 1 (i.e., the separated full tray 1) remains on the full tray support plate 2300 and is driven by the first lifting drive assembly 2200 to move down until the full tray 1 lands on the conveyor line 1000 and is conveyed by the conveyor line 1000 to the position of the feeding mechanism 3000. The separation of the remaining full trays 1 is carried out in this way successively.

[0062] Since the full tray 1 needs to move downward with the full tray support plate 2300, to ensure the position stability of the full tray 1 on the full tray support plate 2300, such as Figure 8As shown, a plurality of suction cups 2310 are arranged on the full tray support plate 2300, which firmly adsorb the full tray 1 on the full tray support plate 2300 during the downward movement, and when the full tray 1 moves downward to contact the conveyor line 1000, the suction cups 2310 release the full tray 1, causing it to detach from the full tray support plate 2300 and be further conveyed along the conveyor line 1000.

[0063] As can be seen from the above-mentioned disk separation action, the chuck component 2410 needs to be able to move freely in and out, and the chuck driving component must include both a part that drives it to move inward and a part that drives it to move outward. In some embodiments of the utility model, the chuck driving component includes an elastic component 2420, one end of which is fixed and the other end is against the chuck component 2410, and the elastic restoring force of the elastic component 2420 drives the chuck component 2410 to move inside the full material tray accommodating space.

[0064] The chuck driving component also includes a lifting driving component 2430, and the first chuck assembly 2400 also includes a first rotating component 2440 rotatably arranged on the first supporting frame body 2110. The first rotating component 2440 includes a first side surface 2441 and a second side surface 2442 located on both sides of its rotating shaft. The first side surface 2441 is used to contact the chuck component 2410, and the second side surface 2442 is used to contact the lifting output end of the lifting driving component 2430.

[0065] The lifting drive component 2430 is configured to lift the first rotating component 2440 through its lifting output end to achieve rotation, thereby pushing the chuck component 2410 to move outside the full material tray accommodating space, thereby achieving the chuck component 2410 to separate from the full material tray 1 and compress the elastic component 2420.

[0066] Specifically, the lifting drive component 2430 is arranged in the space below the first support frame 2100 and is arranged one-to-one with the first chuck assembly 2400. When the chuck component 2410 is in the supporting position extending into the full material tray accommodating space, as shown in FIG. Figure 5 and Figure 6 As shown, the elastic component 2420 is in a natural state, and the first rotating component 2440 is located above the lifting drive component 2430. After the lifting output end of the lifting drive component 2430 extends upward to contact the second side surface 2442 of the first rotating component 2440, it continues to extend upward to lift the first rotating component 2440 to rotate, so that the first rotating component 2440 rotates toward the outside of the full material tray accommodating space, and then the contact between its first side surface 2441 and the chuck component 2410 pushes the chuck component 2410 to move toward the outside of the full material tray accommodating space, so that the chuck component 2410 is separated from the supported full material tray 1, and at the same time, the chuck component 2410 compresses the elastic component 2420. Figure 7 shown.

[0067] In some embodiments of the present invention, the first rotating member 2440 is a V-shaped block, and the first rotating member shaft 2443 is located at the bottom tip of the V-shaped block. The first rotating member shaft 2443 is a horizontal axis and is parallel to the conveying direction of the conveying line 1000, and the expansion and contraction direction of the elastic member 2420 is perpendicular to the conveying direction of the conveying line 1000.

[0068] Furthermore, a sliding guide structure that cooperates with each other is provided between the chuck component 2410 and the first supporting frame body 2110, and the chuck driving component drives the chuck component 2410 to slide inside or outside the full material tray accommodating space. Figure 5 As shown, the sliding guide structure includes a slide rail 2120 fixed on the first support frame body 2110 and a slider 2411 fixed on the bottom surface of the chuck component 2410. The slider 2411 cooperates with the slide rail 2120 to ensure reliable movement of the chuck component 2410.

[0069] The chuck member 2410 has an extension portion 2412 extending toward the side where the first rotating member 2440 is located, and the first side surface 2441 of the first rotating member 2440 is located above the extension portion 2412 and in contact with the extension portion 2412, and the contact surface of the two is an arc surface. That is, the chuck member 2410 is in contact with the first side surface 2441 of the first rotating member 2440 through its extension portion 2412, and the contact portion between the chuck member 2410 and the first rotating member 2440 can be guided to one side to avoid interference with the tray.

[0070] The first side surface 2441 of the first rotating component 2440 contacts the extension portion 2412 through an arc surface. For example, the extension portion 2412 is cylindrical and the first side surface 2441 is a concave arc surface. This can improve the guarantee of smooth relative movement between the first rotating component 2440 and the extension portion 2412, and the concave arc surface can also have a certain limiting effect on the cylindrical extension portion 2412, which is beneficial to prevent the extension portion 2412 from detaching from the first side surface 2441.

[0071] The chuck component 2410 is specifically in the shape of a block, and its inner edge is a thin horizontal plate. This part is the support part 2413 of the chuck component 2410 to support the full material tray 1; the other parts of the chuck component 2410 are thicker to ensure its structural strength. The extension part 2412 is located on one of its left and right sides, and the elastic part 2420 is correspondingly located on the other side.

[0072] The first chuck assembly 2400 further includes a first fixed seat 2450, which is fixedly arranged on the first support frame body 2110. The rotating shaft 2443 of the first rotating member is installed on the first fixed seat 2450. During installation, the first rotating member 2440 and the first fixed seat 2450 can be pre-assembled into one body first and then installed on the first support frame body 2110, improving the installation convenience.

[0073] The first chuck assembly 2400 further includes a guiding member 2460 arranged on the first support frame body 2110. The guiding member 2460 is in sliding guiding cooperation with the elastic member 2420 to guide the telescopic movement of the elastic member 2420.

[0074] The elastic member 2420 can specifically be a spring, and the guiding member 2460 is specifically a guide post, which is fixedly arranged on the first support frame body 2110 through a bracket. The spring is sleeved on the guide post; a through hole is formed on the side part of the chuck member 2410, which is also sleeved on the guide post, and the elastic member 2420 is clamped between the chuck member 2410 and the bracket.

[0075] For the lifting drive member 2430 of the first chuck assembly 2400, refer to Figure 8 , which is integrated with the full-material tray support plate 2300. The lifting output end of the lifting drive member 2430 avoids the full-material tray support plate 2300 so as to smoothly lift the first rotating member 2440 to rotate. The integration of the lifting drive member 2430 and the full-material tray support plate 2300 also makes the entire full-material tray sub-disk mechanism 2000 have a compact structure and occupy a small space.

[0076] The lifting drive member 2430 of the first chuck assembly 2400 can be selected as a cylinder or an oil cylinder, etc. The first lifting drive assembly 2200 can also be selected as a cylinder or an oil cylinder, etc. The cylinder or the oil cylinder is arranged vertically and is fixedly arranged on the foundation (such as the ground) through a fixed support.

[0077] As Figure 8 shown, a plurality of downwardly extending mounting plates 2470 are circumferentially arranged corresponding to the bottom surface of the full-material tray support plate 2300. The lifting drive member 2430 is correspondingly installed on each mounting plate 2470, and its position is lower than the full-material tray support plate 2300 to avoid the full-material tray support plate 2300 from supporting the full-material tray 1. A vertically upwardly extending jacking rod 2431 is fixedly arranged on the output end of the lifting drive member 2430, which is used to contact the second side surface 2442 of the first rotating member 2440 to lift the first rotating member 2440 to rotate.

[0078] In some embodiments of the present utility model, as Figures 1 to 4As shown, since the outer contour of the tray is usually rectangular, the first support frame body 2110 is in the shape of a rectangular frame. A plurality of first chuck assemblies 2400 are respectively arranged at the four corners of the first support frame body 2110, specifically on two relatively arranged support beams of the first support frame body 2110. The length directions of these two support beams are parallel to the conveying direction of the conveying line 1000. Then, the number of the first chuck assemblies 2400 is four sets, and one set of the first chuck assemblies 2400 is arranged at each end of each support beam. The first chuck assemblies 2400 on the two support beams are arranged oppositely.

[0079] The full - material tray 1 is coaxial with the first support frame body 2110. The inner contour dimension of the first support frame body 2110 is larger than the outer contour dimension of the full - material tray 1, so that when the first chuck assembly 2400 retracts outward and disengages from the full - material tray 1, the full - material tray 1 can smoothly fall onto the full - material tray support plate 2300.

[0080] The first support frame 2100 further includes a plurality of full - material tray limiting columns 2130 arranged on the first support frame body 2110 along the extension direction of the first support frame body 2110. The full - material tray limiting columns 2130 extend vertically. Together with the first support frame body 2110, they enclose a full - material tray accommodating space. The plurality of full - material tray limiting columns 2130 can surround the stacked full - material trays 1 inside, restricting the trays from sliding outward and improving the safety of the entire full - material tray disk - separating mechanism 2000.

[0081] Furthermore, the cross - section of the full - material tray limiting column 2130 is rectangular, and a guiding inclined surface is formed at the top of its inner side surface (i.e., the side surface of the circumferential side of the limiting column 4120 facing the full - material tray accommodating space), so as to play a guiding role when placing the stacked full - material trays 1 and facilitate the placement of the stacked full - material trays 1.

[0082] In some embodiments of the present utility model, as Figure 1 , Figure 9 and Figure 10 shown, the second lifting drive assembly 3100 of the feeding mechanism 3000 can also be selected as a cylinder or an oil cylinder, etc. The cylinder or the oil cylinder is erected and fixedly arranged on the foundation (such as the ground) through a fixed support.

[0083] The feeding tray support plate 3200 is horizontally and fixedly arranged at the top of the lifting output end of the second lifting drive assembly 3100. To ensure the position stability of the feeding tray on the feeding tray support plate 3200, as Figure 10 shown, a plurality of suction cups are also arranged on the feeding tray support plate 3200. During the feeding process, the feeding tray is firmly adsorbed on the feeding tray support plate 3200. When moving down until the tray contacts the conveying line 1000, the suction cups release the tray, enabling it to disengage from the feeding tray support plate 3200 and be further conveyed along with the conveying line 1000.

[0084] In some embodiments of the present utility model, the empty tray collecting mechanism can be a simple collecting device such as a collecting box. The empty tray collecting mechanism is located at the end of the conveying line 1000. After the empty material tray 2 is conveyed to the end by the conveying line 1000, it directly drops into the empty tray collecting mechanism.

[0085] To achieve the orderly stacking and collection of the empty material trays 2, in some embodiments of the present utility model, referring to Figures 11 to 15 , the tray collecting mechanism 4000 includes a second support frame 4100, a third lifting drive assembly 4200, and a plurality of second chuck assemblies 4300. The second support frame 4100 encloses an accommodation space for the empty material trays. The second support frame 4100 includes a second support frame body 4110; an empty material tray support plate 4400 is provided on the lifting output end of the third lifting drive assembly 4200; a plurality of second chuck assemblies 4300 are arranged on the second support frame body 4110 along the extending direction of the second support frame body 4110; the third lifting drive assembly 4200 is configured to drive the empty material tray 2 to move upward into the accommodation space of the empty material trays through the empty material tray support plate 4400 when the empty material tray 2 reaches the empty material tray support plate 4400, and support the empty material tray 2 on the second chuck assemblies 4300.

[0086] In this embodiment, the tray collecting mechanism 4000 can stack the empty material trays 2 one by one from bottom to top, realizing the automatic, orderly and stacked collection of the empty material trays 2, greatly improving the collection efficiency of the empty material trays 2, and facilitating the subsequent centralized handling or processing after the collection of the empty material trays 2.

[0087] In the initial state, the lifting output end of the third lifting drive assembly 4200 drives the empty material tray support plate 4400 to be located below the conveying line 1000, as Figure 13As shown in the figure, when the empty tray 2 is conveyed by the conveyor line 1000 to the empty tray support plate 4400, the lifting output end of the third lifting drive assembly 4200 extends upward, lifting the empty tray 2 upward to move it away from the conveyor line 1000. When the empty tray 2 reaches above the second chuck assembly 4300, the lifting output end of the third lifting drive assembly 4200 retracts downward, and the empty tray 2 lands on the second chuck assembly 4300 and is supported on the second chuck assembly 4300. When the next empty tray 2 reaches the empty tray support plate 4400, the lifting output end of the third lifting drive assembly 4200 extends upward, lifting the empty tray 2 upward to move it away from the conveyor line 1000. When this empty tray 2 contacts the empty tray 2 that has been collected earlier, the lifting output end of the third lifting drive assembly 4200 continues to extend upward, lifting this empty tray 2 and the collected empty trays 2 together above the second chuck assembly 4300. Then, the lifting output end of the third lifting drive assembly 4200 retracts downward, and this empty tray 2 and the collected empty trays 2 together land on the second chuck assembly 4300 and are supported on the second chuck assembly 4300. The remaining empty trays 2 are collected in this way in sequence, realizing the stack collection of the empty trays 2 from bottom to top.

[0088] From the above-described empty tray 2 collection operation, it can be seen that the second chuck assembly 4300 needs to be able to avoid the empty tray 2 when the empty tray 2 moves upward, and be able to support the empty tray 2 when the empty tray 2 descends above the second chuck assembly 4300 and is supported on the second chuck assembly 4300. Then, it is required that the empty tray 2 can move to a position to avoid the empty tray 2 and can also move to the support position.

[0089] Then, in some embodiments of the present invention, the second chuck assembly 4300 includes a second rotating member 4310. The second rotating member 4310 is rotatably arranged on the second support frame body 4110, and it can rotate to an avoidance position for avoiding the upward movement of the empty tray 2 and a support position for supporting the empty tray 2. That is, when the empty tray 2 moves upward, the second rotating member 4310 rotates to the avoidance position to avoid the upward movement of the empty tray 2 above the second chuck assembly 4300. Subsequently, the second rotating member 4310 rotates to the support position to support the empty tray 2, restricting the continued downward movement of the empty tray 2, and only the lifting output end of the third lifting drive assembly 4200 retracts downward to return to its original position.

[0090] As a specific implementation manner, as Figures 12 to 15 shown, the second rotating member 4310 is a triangular block structure, the inner edge of its top surface is its planar support surface 4311, and the second rotating member rotating shaft 4312 is located at the bottom tip of the triangular block.

[0091] The rotating shaft 4312 of the second rotating member is a horizontal axis and is parallel to the conveying direction of the conveying line 1000. The rotating shaft 4312 of the second rotating member is eccentrically connected to the second rotating member 4310. Under the self-weight of the second rotating member 4310, the second rotating member 4310 can rotate to the supporting position, and under the action of an external force, the second rotating member 4310 rotates towards the avoiding position.

[0092] As Figures 12 to 15 From the perspective shown, the second rotating member 4310 rotates counterclockwise to the supporting position and clockwise to the avoiding position. When in the supporting position, the planar supporting surface 4311 of the second rotating member 4310 is in a horizontal state and is located on the upward and downward movement paths of the empty tray 2 to fit and abut against the outer turned edge 21 of the bottom edge of the empty tray 2.

[0093] The rotational driving force for the second rotating member 4310 to rotate towards the avoiding position comes from the thrust of the upwardly moving empty tray 2. That is, when the lifting output end of the third lifting drive assembly 4200 jacks up the empty tray 2 through the empty tray support plate 4400, the empty tray 2 moves upward to contact the bottom of the second rotating member 4310 located in the supporting position. Continuing to lift, the empty tray 2 continues to move upward, which pushes the second rotating member 4310 to rotate clockwise. The upward movement direction of the empty tray 2 and the rotational direction of the second rotating member 4310 are as Figure 13 shown by the dotted arrows. When the empty tray 2 pushes the second rotating member 4310 to rotate clockwise until the empty tray 2 is about to disengage from the second rotating member 4310, the position of the second rotating member 4310 at this time is the avoiding position (at this time, the planar supporting surface 4311 of the second rotating member 4310 is approximately parallel to the vertical direction). The empty tray 2 continues to move upward and disengages from the second rotating member 4310. The empty tray 2 reaches above the second rotating member 4310. The second rotating member 4310 rotates back to the supporting position under its own weight. Then, the lifting output end of the third lifting drive assembly 4200 retracts downward, driving the empty tray 2 to move downward to be supported on the planar supporting surface 4311 of the second rotating member 4310, realizing the collection of the empty tray 2.

[0094] For the second rotating member 4310 with the above structure, there is no need to additionally provide a rotating drive structure for driving its rotation. The second chuck assembly 4300 has a simple structure, few actions, and more stable operation.

[0095] The second chuck assembly 4300 further includes a limiting member 4320, which is used to abut against the second rotating member 4310 when the empty tray 2 is supported on the second rotating member 4310, restricting the rotation of the second rotating member 4310 and enabling the second rotating member 4310 to stably remain in the supporting position, further improving the supporting reliability.

[0096] As Figure 12 、 Figure 14 andFigure 15 As shown, the limiting component 4320 is a limiting stop rod fixedly arranged on the second support frame body 4110. It is located above the second rotating component 4310 and near the outer edge of the top surface, and its plane support surface 4311 of the second rotating component 4310 and the limiting component 4320 are respectively located on both sides of the rotating shaft 4312 of the second rotating component. When the empty tray 2 is supported on the second rotating component 4310, the gravity of the empty tray 2 will cause the second rotating component 4310 to have a tendency to rotate counterclockwise. At this time, the limiting component 4320 abuts against and stops the second rotating component 4310 to restrict its rotation, so that the empty tray 2 can be stably supported on the second rotating component 4310.

[0097] In some embodiments of the present invention, the second chuck assembly 4300 further includes a second fixed seat 4330. The second fixed seat 4330 is fixedly arranged on the second support frame body 4110. The rotating shaft 4312 of the second rotating component is installed on the second fixed seat 4330, and the limiting component 4320 is also installed on the second fixed seat 4330. Then during installation, the second rotating component 4310, the limiting component 4320 and the second fixed seat 4330 can be pre-assembled into one body first, and then installed on the second support frame body 4110, which improves the installation convenience.

[0098] When the third lifting drive assembly 4200 drives the empty tray 2 to move upward through the empty tray support plate 4400, the empty tray 2 pushes the second rotating component 4310 to rotate to avoid the empty tray 2 moving upward above the second rotating component 4310. When the third lifting drive assembly 4200 drives the empty tray support plate 4400 to move downward and separate from the empty tray 2, the empty tray 2 is supported on the second rotating component 4310.

[0099] Similarly, since the outer contour of the tray is usually rectangular, the second support frame body 4110 is in the shape of a rectangular frame, as Figure 11 shown, a plurality of second chuck assemblies 4300 are respectively arranged at the four corner parts of the second support frame body 4110, specifically arranged on two relatively arranged support beams of the second support frame body 4110. The length directions of these two support beams are parallel to the conveying direction of the conveying line 1000. Then the number of the second chuck assemblies 4300 is four sets, and one set of the second chuck assembly 4300 is arranged at each end of each support beam. The second chuck assemblies 4300 on the two support beams are arranged oppositely.

[0100] The empty tray 2 and the second support frame body 4110 are coaxial. The inner contour dimension of the second support frame body 4110 is larger than the outer contour dimension of the empty tray 2 and also larger than the outer contour dimension of the empty tray support plate 4400, so that the empty tray support plate 4400 can drive the empty tray 2 to move upward or downward through the inner space of the second support frame body 4110.

[0101] The second support frame 4100 also includes a plurality of empty tray limiting columns 4120 disposed on the second support frame body 4110 along the extending direction of the second support frame body 4110. The empty tray limiting columns 4120 extend vertically, and together with the second support frame body 4110, they enclose an empty tray accommodating space. The plurality of empty tray limiting columns 4120 can surround the stacked empty trays 2, restricting the outward sliding of the empty trays 2 and improving the use safety of the entire tray collecting mechanism 4000.

[0102] Furthermore, the cross-section of the empty tray limiting column 4120 is rectangular, and a guiding inclined surface is formed at the top of its inner side surface (i.e., the side surface of the circumferential side of the empty tray limiting column 4120 facing the empty tray accommodating space), so as to play a guiding role when placing the stacked full trays 1, facilitating the placement of the stacked empty trays 2.

[0103] When the second support frame body 4110 is in the shape of a rectangular frame, the empty tray limiting columns 4120 are disposed on its four support beams, and the empty tray limiting columns 4120 on two opposite support beams are symmetrically arranged, and the height position of their tops is lower than the height position of the tops of the empty tray limiting columns 4120 on the other two opposite support beams, as Figure 11 shown, so that when the stacking quantity of the empty trays 2 is large, the empty trays 2 can be taken away part by part from the upper side part, facilitating tray taking.

[0104] The third lifting drive assembly 4200 can be selected as a cylinder or an oil cylinder, etc. The cylinder or the oil cylinder is erected and fixedly arranged on the foundation (such as the ground) through a fixed support.

[0105] In some embodiments of the present utility model, referring to Figure 9 and in combination with Figure 1 , the conveyor line 1000 is a double-belt conveyor line. The two belt conveyor lines act synchronously. The two belt conveyor lines are arranged oppositely and spaced apart by a certain distance, providing an installation space for the full tray dividing mechanism 2000, the feeding mechanism 3000 and the tray collecting mechanism 4000, and providing an avoidance space for the related actions of each moving part, such as the lifting of the corresponding support plate driven by the lifting output end.

[0106] The widths of the full tray support plate 2300, the feeding tray support plate 3200 and the empty tray support plate 4400 are all smaller than the distance between the two belts of the conveyor line 1000, so that the conveyor line 1000 can avoid the lifting of the full tray support plate 2300, the feeding tray support plate 3200 and the empty tray support plate 4400.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
