Traditional manual operation may cause sweat stains, static electricity, fatigue, and non-standard operation, which affects the efficiency of material taking and the efficiency of material taking. The common automatic feeding mechanism on the market mainly uses a single jacking assembly to sequentially pass through the full tray area, the material taking position and the empty tray area to transport the tray. However, this mechanism is large in size, and there is a long empty gear when replacing the tray, which leads to bloated production line design, waste of time and space, and is not conducive to the establishment of lean production line.

[0051] The technical scheme of the present application is further illustrated below by combining the drawings and through specific embodiments.

[0052] The present embodiment provides a double-layer reciprocating type feeding device, which comprises Figures 1-4As shown, the double-layer reciprocating feeding device includes a tray grabbing unit 1, a product feeding unit 2, and a tray conveying unit 3. The tray grabbing unit 1 includes a first transfer assembly 11, and the output end of the first transfer assembly 11 is provided with a tray grabbing piece 12 configured to grab a tray on which products are loaded. The product feeding unit 2 includes a second transfer assembly 21, and the output end of the second transfer assembly 21 is provided with a product grabbing piece 22 configured to grab the products on the tray. The tray conveying unit 3 includes an upper conveying assembly 31 and a lower conveying assembly 32, both of which are capable of reciprocating in the direction from the tray grabbing piece 12 to the product grabbing piece 22. The tray grabbing piece 12 can sequentially grab the trays loaded with products to the upper conveying assembly 31 and the lower conveying assembly 32, and can sequentially grab the trays from the upper conveying assembly 31 and the lower conveying assembly 32. When feeding the trays, the first transfer assembly 11 drives the tray grabbing piece 12 to grab the trays loaded with products, which are sequentially placed on the upper conveying assembly 31 and the lower conveying assembly 32. The two conveying assemblies sequentially convey the trays to the corresponding working positions of the product grabbing piece 22, and the second transfer assembly 21 drives the product grabbing piece 22 to grab the products in the tray of the upper conveying assembly 31. When the feeding of the products in the tray of the upper conveying assembly 31 is completed, the upper conveying assembly 31 moves the tray thereon in the direction from the product grabbing piece 22 to the tray grabbing piece 12. Then, the tray grabbing piece 12 grabs the tray, and the tray loaded with products is placed on the upper conveying assembly 31 again. In this process, the second transfer assembly 21 drives the product grabbing piece 22 to grab the products in the tray of the lower conveying assembly 32. When the feeding of the products in the tray of the lower conveying assembly 32 is completed, the upper conveying assembly 31 sequentially conveys the trays to the corresponding working positions of the product grabbing piece 22. Then, the lower conveying assembly 32 repeats the process of the upper conveying assembly 31. In this way, the parallel feeding of the trays is realized. Through the arrangement of the upper conveying assembly 31 and the lower conveying assembly 32, the tray conveying and recycling can be simultaneously processed, the cycle period of the tray feeding is shortened, the congestion of the trays at the feeding end of the upper conveying assembly 31 and the lower conveying assembly 32 is avoided, the feeding capacity of the trays is improved, and the feeding efficiency of the products in the trays is improved. In addition, since the upper conveying assembly 31 and the lower conveying assembly 32 are arranged in parallel, when one of them fails, the feeding process of the trays can still proceed normally, ensuring the continuity of the tray process and improving the stability of the double-layer reciprocating feeding device.

[0053] Specifically, as Figure 1As shown, in the embodiment, the output end of the second transfer assembly 21 is provided with two spaced product grabbing members 22.

The upper layer tray frame 312 is used for placing a tray, and the upper layer transfer driving member 311 is configured to drive the upper layer tray frame 312 to reciprocally move in the direction from the tray grabbing member 12 to the product grabbing member 22. The tray grabbing member 12 grabs a tray onto the upper layer tray frame 312, and then the upper layer transfer driving member 311 is started and drives the upper layer tray frame 312 to move in the direction from the tray grabbing member 12 to the product grabbing member 22. Then, the second transfer assembly 21 drives the product grabbing member 22 to grab the product in the tray of the upper layer transfer assembly 31. When the product in the tray of the upper layer tray frame 312 is finished, the upper layer transfer driving member 311 is reversely started and drives the upper layer tray frame 312 and the tray thereon to move in the direction from the product grabbing member 22 to the tray grabbing member 12. Then, the tray grabbing member 12 grabs the tray and places the tray loaded with products onto the upper layer tray frame 312 again. Through the above arrangement, the reciprocating feeding of the tray on the upper layer tray frame 312 is realized, and the feeding efficiency of the tray on the upper layer tray frame 312 is improved.

[0057] Specifically, in the embodiment, the upper layer transfer driving member 311 is a first rodless cylinder. In other embodiments, the upper layer transfer driving member 311 is a first motor or the like. This is not limited here.

[0058] Specifically, as shown in Figure 2As shown, in the embodiment, the first rodless cylinder is connected with a first synchronous member 313, and the first synchronous member 313 is fixedly connected with the upper tray frame 312. In other embodiments, the first motor is drivingly connected with the upper tray frame 312 through the screw sliding table and the first synchronous member 313. Specifically, in the embodiment, the first synchronous member 313 is a first synchronous bracket. In other embodiments, the first synchronous member 313 is a first synchronous rod or a first synchronous plate, etc. This is not limited here.

[0059] Optionally, as shown, Figure 2 As shown, the double-layer reciprocating feeding device further comprises a mounting unit, and the tray conveying unit 3 further comprises a first guide assembly 33, the first guide assembly 33 comprising a first guide rail 331 and a first sliding block 332 which are slidingly connected, the first guide rail 331 extending in the direction from the tray grabbing member 12 to the product grabbing member 22, one of the first guide rail 331 and the first sliding block 332 being arranged on the upper tray frame 312, and the other being arranged on the mounting unit. The arrangement of the first guide rail 331 and the first sliding block 332 can provide a guiding effect for the movement of the upper tray frame 312, thereby ensuring the stability and reliability of the reciprocating movement of the upper tray frame 312.

[0060] Specifically, in the embodiment, the first sliding block 332 is arranged on the upper tray frame 312, and the first guide rail 331 is arranged on the mounting unit. In other embodiments, the first sliding block 332 is arranged on the mounting unit, and the first guide rail 331 is arranged on the upper tray frame 312, etc. This is not limited here.

[0061] Specifically, in the embodiment, the first guide assembly 33 is provided in two groups, and the two groups of first guide assemblies 33 are arranged in a direction perpendicular to the direction from the tray grabbing member 12 to the product grabbing member 22.

[0062] Optionally, as shown, Figure 1 and Figure 2As shown, the lower-level transmission component 32 includes a lower-level transmission drive 321 and a lower-level material tray frame 322. The lower-level transmission drive 321 is fixedly installed, and the lower-level material tray frame 322 is throttle-connected to the output end of the lower-level transmission drive 321. The lower-level material tray frame 322 is used to place the material tray, and the lower-level transmission drive 321 is configured to drive the lower-level material tray frame 322 to reciprocate along the direction from the material tray gripper 12 to the product gripper 22. The tray gripper 12 grips the tray onto the lower tray frame 322. Then, the lower transfer drive 321 starts and moves the lower tray frame 322 along the direction from the tray gripper 12 to the product gripper 22. Next, the second transfer assembly 21 drives the product gripper 22 to grip the product in the tray of the lower tray frame 322. Once the product unloading from the tray of the lower tray frame 322 is complete, the lower transfer drive 321 starts in reverse and moves the lower tray frame 322 and its trays along the direction from the product gripper 22 to the tray gripper 12. Then, the tray gripper 12 grips the tray and re-grips the tray loaded with products, placing it back onto the upper transfer assembly 31. This configuration enables reciprocating feeding of the trays on the lower tray frame 322, improving the feeding efficiency of the trays on the lower tray frame 322.

[0063] Specifically, in this embodiment, the lower-level transmission drive 321 is a second rodless cylinder. In other embodiments, the lower-level transmission drive 321 is a second motor, etc. No limitations are imposed here.

[0064] Specifically, such as Figure 2 As shown, in this embodiment, the slide of the second rodless cylinder is connected to a second synchronizing element 323, which is fixedly connected to the lower material tray frame 322. In other embodiments, the second motor is driven by the lead screw slide and the second synchronizing element 323 to the lower material tray frame 322. Specifically, in this embodiment, the second synchronizing element 323 is a second synchronizing bracket. In other embodiments, the second synchronizing element 323 is a second synchronizing rod or a second synchronizing plate, etc. No limitation is made here.

[0065] Optionally, such as Figure 2 As shown, the double-layer reciprocating feeding device also includes an installation unit, and the tray transfer unit 3 further includes a third guide assembly. The third guide assembly includes a third guide rail and a third slider that are slidably connected. The third guide rail extends along the direction from the tray gripper 12 to the product gripper 22. Two of the third guide rail and the third slider are disposed in the lower tray frame 322, and the other one is disposed in the installation unit. The third guide rail and the third slider provide guidance for the movement of the lower tray frame 322, ensuring the stability and reliability of the reciprocating movement of the lower tray frame 322.

[0066] Specifically, in this embodiment, the third slider is disposed on the lower tray frame 322, and the third guide rail is disposed on the mounting unit. In other embodiments, the third slider is disposed on the mounting unit, and the third guide rail is disposed on the lower tray frame 322, etc. No limitation is made here. Specifically, in this embodiment, two sets of third guide components are provided, and the two sets of third guide components are spaced apart along a direction perpendicular to the direction from the tray gripper 12 to the product gripper 22.

[0067] Optionally, such as Figure 1 As shown, the double-layer reciprocating feeding device also includes a feeding trolley 4, which contains multiple trays arranged parallel to each other in the vertical direction. The tray gripper 12 can grip the trays in the feeding trolley 4. The feeding trolley 4 allows multiple trays to be stored in a centralized manner, reducing the frequency of tray replenishment and ensuring the continuity of double-layer reciprocating feeding. At the same time, the cooperation between the feeding trolley 4, the trays, and the tray gripper 12 achieves orderly storage and precise gripping of the trays, improving the continuity of tray feeding, space utilization, and operational stability.

[0068] Specifically, such as Figures 1-4 As shown, in this embodiment, the feeding trolley 4 includes a trolley body and four partitions 41 spaced vertically. The four partitions 41 divide the feeding trolley 4 into five layers. Each layer includes two trays spaced vertically. The two trays in each layer are fed to the upper tray frame 312 and the lower tray frame 322, and then the feeding of the two trays in the next layer is carried out. By dividing multiple trays into layers and feeding them in batches, the two trays in each layer are fed simultaneously before moving to the next layer, reducing waiting time. At the same time, clearly dividing the trays into layers avoids tray feeding chaos and facilitates tracking the feeding progress and troubleshooting. Specifically, the partitions 41 are partition plates. Specifically, the trolley body is provided with guide strips, which can move to adapt to the size of the trays.

[0069] Specifically, such as Figures 1-4 As shown, the feeding trolley 4 has a locking hole 411 on the side facing the material tray gripper 12. The double-layer reciprocating feeding device also includes an installation unit, and the material tray transmission unit 3 also includes a locking component 34. The locking component 34 includes a locking drive 341 and a locking actuator 342.

The locking drive 341 is configured to drive the locking actuator 342 to insert into or disengage from the locking hole 411.

[0070] Before the tray grabbing part 12 grabs the tray, the locking driving part 341 is started, and the locking execution part 342 at the output end of the locking driving part 341 is inserted into the locking hole 411 of the feeding trolley 4, so as to fix the relative position of the feeding trolley 4 and the tray conveying unit 3. After the tray grabbing part 12 completes the grabbing of all the trays, the locking driving part 341 is reversely driven, so as to drive the locking execution part 342 to be separated from the locking hole 411, so that the feeding trolley 4 can move relative to the tray conveying unit 3. Through the setting of the locking driving part 341 and the locking execution part 342, the displacement or shaking of the feeding trolley 4 during the grabbing of the tray is avoided, so that the tray grabbing part 12 can accurately align the tray, and the accuracy and stability of the tray grabbing are improved. In addition, the rigid fixing between the locking execution part 342 and the feeding trolley 4 eliminates the collision between the feeding trolley 4 and the tray grabbing part 12 caused by the relative movement between them during the grabbing of the tray. It should be noted that the locking hole 411 is arranged on the partition piece 41.

[0071] Specifically, in the embodiment, as shown in Figure 2 , the locking driving part 341 is a first rod cylinder, the locking execution part 342 is a locking plate with a locking rod, and the locking plate is threadedly connected to the output end of the first rod cylinder.

[0072] Specifically, as shown in Figures 2-4 , two locking rods are arranged on the locking plate. In other embodiments, one locking rod or three locking rods are arranged on the locking plate, etc. This is not limited here. Correspondingly, the locking hole 411 is arranged with two locking holes, and the two locking rods can be inserted into the two locking holes 411.

[0073] Specifically, as shown in Figure 1 , the double-layer reciprocating feeding device further comprises a mounting unit and a trolley lifting unit 5. The trolley lifting unit 5 comprises a trolley lifting body 52 and a trolley lifting driving part 51. The feeding trolley 4 is arranged on the trolley lifting body 52, and the trolley lifting driving part 51 is fixedly arranged on the trolley lifting body 52. The output end of the trolley lifting driving part 51 is in transmission connection with the mounting unit. The trolley lifting driving part 51 is configured to drive the trolley lifting body 52 to lift and lower, so that the trays in the feeding trolley 4 can be pulled out to the upper conveying assembly 31 and the lower conveying assembly 32 in sequence by the tray grabbing part 12.

[0074] The feeding trolley 4 is loaded with multiple layers of trays, and is placed on the trolley lifting body 52. The trolley lifting drive 51 is in the initial position, and then the trolley lifting drive 51 is started to drive the trolley lifting body 52 to rise to the height corresponding to the upper tray frame 312. The tray grabbing element 12 pulls out the tray in the feeding trolley 4 to the upper tray frame 312. After the upper tray frame 312 is transmitted, the tray grabbing element 12 pulls out the next tray to the lower tray frame 322. The lifting positioning and grabbing action is repeated until all the trays in the feeding trolley 4 are sequentially distributed to the upper tray frame 312 and the lower tray frame 322, and the double-layer tray feeding process is completed. The lifting height of the trolley lifting body 52 is accurately controlled by the trolley lifting drive 51, and then the height of the two trays of each layer is controlled, so that the tray grabbing is free of misalignment, the continuity and accuracy of the feeding of the upper tray frame 312 and the lower tray frame 322 are ensured, and the double-layer structure design reduces the equipment floor area, realizes double feeding capacity in limited space, and improves the site utilization rate. It should be noted that the trolley lifting drive 51 is a speed reducer.

[0075] Specifically, as shown in Figure 1 In this embodiment, the output end of the trolley lifting drive 51 is connected in transmission through a screw block structure mounting unit.

[0082] When the upper tray of each layer is horizontally pulled out to the upper tray frame 312, the first lifting drive 114 remains stationary, the second lifting drive 115 is actuated to drive the tray grabbing member 12 to grab the upper tray, and the lower tray is horizontally pulled to the lower tray frame 322 by the action of the second horizontal drive 113. By horizontally pulling the lower tray to the lower tray frame 322, the displacement of the products in the tray caused by unstable docking during the transfer process can be avoided, thereby ensuring the stability of the tray during the feeding process.

[0083] Specifically, the first horizontal drive 111 is a third rodless cylinder, the second horizontal drive 113 is a second rod cylinder and a third rod cylinder, and the second lifting drive 115 is a fourth rod cylinder.
