[0002] In a product packaging line, in many cases, two products need to be put into a box or a bag simultaneously. For example, for a product display panel, the panel sides of two display panels need to be face-to-face for packaging. When one side of a product has an irregular shape, or when the two products are in contact for a long time, wear is likely to occur between the two products, thus affecting the product quality.

[0003] How to automatically pair two products face-to-face in a production line is one of the problems to be solved in this application. Summary of the Invention

[0004] One advantage of the present invention is to provide a product face-to-face pairing device. When a material detection sensor detects a product on a material guide plate, a pulling cylinder, through the cooperation of a pushing plate connecting plate and a pushing plate, pushes product A and product B into two opposite flipping limiting grooves of a first flipping plate and a second flipping plate. Then, through a first flipping shaft and a second flipping shaft, product A and product B are respectively rotated counterclockwise and clockwise by 90°. Then, through a pushing block, the flipped product A and product B are pushed into a first pairing groove and a second pairing groove. Finally, through the relative approaching movement of a first telescopic element and a second telescopic element, the pairing of product A and product B is completed, thereby realizing the automatic pairing of product A and product B on a production line.

[0030] Reference Figures 1 to 6, a product face-to-face pairing device according to a preferred embodiment of the present invention will be described in detail below, wherein the product face-to-face pairing device includes a support frame 10, a material turning mechanism 20, a pairing mechanism 30, and a material pushing mechanism 40. The material turning mechanism 20 is disposed on the top of the support frame 10 and includes a rotating element 21, a first turning shaft 22, and a second turning shaft 23. The first turning shaft 22 and the second turning shaft 23 extend in the same direction and are connected to the rotating shaft of the rotating element 21 in a manner that can be driven to rotate in opposite directions relative to each other. For example, when the rotating element 21 rotates clockwise, the first turning shaft 22 rotates clockwise and the second turning shaft 23 rotates counterclockwise. When the rotating element 21 rotates counterclockwise, the first turning shaft 22 rotates counterclockwise and the second turning shaft 23 rotates clockwise. The first turning shaft 22 and the second turning shaft 23 are respectively fixedly sleeved with a first turning plate 221 and a second turning plate 231. At the same time, the first turning plate 221 and the second turning plate 231 are both provided with turning limiting grooves 201 extending in the cross direction, that is, the first turning plate 221 and the second turning plate 231 are both provided with four turning limiting grooves 201 of the same size at equal intervals in the circumferential direction, and each of the turning limiting grooves 201 thereon can respectively place product A and product B;

[0031] Among them, in combination with Figure 2 , the pairing mechanism 30 is arranged side by side with the material turning mechanism 20 in the horizontal direction and is fixedly connected to the support frame 10 through a fixing plate 33. The pairing mechanism 30 includes a first telescopic element 31 and a second telescopic element 32 that are relatively and symmetrically arranged, such that when the first telescopic element 31 and the second telescopic element 32 extend simultaneously, their telescopic ends are relatively gradually approaching. The telescopic ends of the first telescopic element 31 and the second telescopic element 32 are respectively connected with a first pairing groove 301 and a second pairing groove 302, and the first pairing groove 301 and the second pairing groove 302 are respectively opposite the turning limiting grooves 201 with upward openings on the first turning plate 221 and the second turning plate 231 in the initial position;

[0032] Among them, in combination with Figure 3 and Figure 4, the pusher mechanism 40 includes a retracting cylinder 41, a pusher connecting plate 42, a material guiding plate 43, a push plate 44, a push block 45 and a material detection sensor 46. Among them, the pusher connecting plate 42 is connected to the retracting cylinder 41 in a manner that can be driven to approach or move away from the material turning mechanism 20 relatively outside the material turning mechanism 20. The material guiding plate 43 cooperates with the pusher connecting plate 42 and is horizontally connected to the support frame 10 below the pusher connecting plate 42 and faces two opposite turning limit slots 202 on the first turning plate 221 and the second turning plate 231 for placing product A and product B. The push plate 44 is horizontally connected to the inner side of the pusher connecting plate 42 and is located above the material guiding plate 43 to be able to push the product A and the product B on the material guiding plate 43 into the two opposite turning limit slots 202 respectively. At the same time, the push block 45 extends in the same direction as the push plate 44 and faces the turning limit slots 201 with upward openings on the first turning plate 221 and the second turning plate 231 respectively to be able to push the product A and the product B into the first mating slot 301 and the second mating slot 302 respectively. The detection end of the material detection sensor 46 faces above the material guiding plate 43.

[0033] Briefly speaking, when the material detection sensor 46 detects the product on the material guiding plate 43, generally, product A and product B move to the material guiding plate 43 synchronously, continuously and horizontally from two opposite directions:

[0034] First, the retracting cylinder 41 retracts the pusher connecting plate 42, and then the push plate 44 synchronously pushes the product A and the product B on the material guiding plate 43 into the two opposite turning limit slots 202.

[0035] Then, the retracting cylinder 41 resets the pusher connecting plate 42.

[0036] Then, the rotating element 21 synchronously drives the first turning shaft 22 to rotate counterclockwise and the second turning shaft 23 to rotate clockwise, so that the two opposite turning limit slots 202 originally accommodating product A and product B both rotate to the state with upward openings. At this time, product A and product B are placed face to face in the vertical direction.

[0037] Then, the second group of products C and D are placed on the material guiding plate 43.

[0038] Then, the pushing plate connecting plate 42 is pulled back by the pulling-back cylinder 41. At this time, the pushing plate 44 will push the products C and D into the two flipping limiting slots 202 where the first flipping plate 221 and the second flipping plate 231 face each other. At the same time, the pushing block 45 will push the products A and B from the flipping limiting slot 201 with an upward opening into the first pairing slot 301 and the second pairing slot 302, and so on, continuously and automatically completing the pairing work of multiple groups of products. The automation degree is high, which can effectively improve the work efficiency, reduce the labor intensity of workers, and reduce the labor cost expenditure.

[0039] As a preferred embodiment, in combination with Figure 5 and Figure 6 , the rotating element 21 is implemented as a servo motor. At the same time, the material flipping mechanism 20 further includes a first rotating shaft 24, a second rotating shaft 25, a first synchronous belt 26 and a second synchronous belt 27. The rotating shaft of the rotating element 21 is connected to the first rotating shaft 24 through a coupling 28, and the first rotating shaft 24 is connected to the first flipping shaft 22 through a synchronous pulley 241 and the first synchronous belt 26. The second rotating shaft 25 and the first rotating shaft 24 are connected by gears sleeved on them respectively, and the second rotating shaft 25 is connected to the second flipping shaft 23 through a synchronous pulley 251 and the second synchronous belt 26. In this way, through the cooperation of the rotating element 21, the first rotating shaft 24, the second rotating shaft 25, the first synchronous belt 26 and the second synchronous belt 27, the first flipping shaft 22 and the second flipping shaft 23 can rotate automatically, with high precision and synchronously in the reverse direction, and the rotation speed, rotation angle and rotation start / stop time are controllable.

[0040] Further preferably, an angle photoelectric detection sensor 29 for detecting the rotation angle is installed on the first flipping shaft 22 and / or the second flipping shaft 23. At the same time, the angle photoelectric detection sensor 29 is connected to an alarm element. When the angle photoelectric detection sensor 29 monitors that the first flipping shaft 22 and / or the second flipping shaft 23 cannot flip in place within a certain time range, it sends a monitoring abnormal signal to the controller, and the controller issues an alarm through the alarm element when receiving the abnormal information, reminding the staff to deal with it in time to avoid affecting the work efficiency or protecting the equipment from worse damage.

[0041] Further preferably, the alarm element is implemented as a sound alarm element and / or a light alarm element. The sound alarm element can be a buzzer. The light alarm element can be a flash lamp or a signal lamp.

[0042] Further preferably, in combination with Figure 2, the face-to-face pairing device further includes a transfer mechanism 50, wherein the transfer mechanism 50 includes a transfer cylinder 51, a lifting cylinder 52 and a material scraper 53. The lifting cylinder 52 is located directly above the contact position of the first pairing groove 301 and the second pairing groove 302. The material scraper 53 is connected to the telescopic end of the bottom of the lifting cylinder 52 and is located on the side close to the material pushing connecting plate 42 at the contact position in the vertical direction. At the same time, the transfer cylinder 51 extends horizontally above the pairing mechanism 30 and is connected to the lifting cylinder 52 through its output end. In this way, when product A and product B are pushed to the middle position by the first telescopic element 31 and the second telescopic element 32 through the first pairing groove 301 and the second pairing groove 302 respectively, the lifting cylinder 52 drives the material scraper 53 to move down to the side of product A and product B close to the material turning plate, and then the transfer cylinder 51 drives the lifting cylinder 52 and the material scraper 53 to move in a direction gradually away from the material turning plate, sending product A and product B out of the device and transferring them to the next process, which can further improve work efficiency.

[0043] In one embodiment, the transfer cylinder 51 is implemented as a rodless cylinder.

[0044] Further preferably, the pulling-back cylinder 41 is connected to the top of the support frame 10 through a cylinder fixing plate 411 and is vertically connected to the material pushing connecting plate 42 through a cylinder telescopic rod 412, making the overall structure of the face-to-face pairing device for products more compact and reducing the occupied space.

[0045] Further preferably, combined Figure 3 and Figure 4 , the material pushing mechanism 40 further includes guide shafts 44 symmetrically arranged on both sides of the cylinder telescopic rod 412. One end of the guide shaft 47 is vertically connected to the material pushing connecting plate 42, and the other end of the guide shaft 47 is connected to the cylinder fixing plate 411 through a linear bearing 48 to ensure the stability and reliability of the pulling-back cylinder 41 driving the material pushing connecting plate 42, the material pushing plate 44 and the material pushing block 45.

[0046] Further preferably, the material pushing mechanism 40 further includes a pressing plate 49. The pressing plate 49 is horizontally arranged above the material guiding plate 43 and maintains a predetermined distance greater than the heights of product A and product B from the material guiding plate 43 to prevent the products on the material guiding plate 43 from being stacked or the products from rebounding upward. In addition, the material pushing connecting plate 42 is provided with a strip-shaped hole 402 adapted to accommodate the pressing plate 49.

[0047] Further preferably, the material guide plate 43 is symmetrically provided with baffle plates 431 on both sides in the extending direction of the cylinder telescopic rod 412, so as to ensure that the products placed on the material guide plate 43 will not slip and fall, or in other words, to ensure that the products are placed at appropriate positions on the surface of the material guide plate 43, so as to facilitate the subsequent smooth pushing of the products into the flipping limit slots 201 where the first flipping plate 221 and the second flipping plate 231 face each other by the pushing plate 44.

[0048] It should be noted that in the present invention, the terms "first" and "second" are only used for descriptive purposes, do not represent any order, and cannot be understood as indicating or implying relative importance, and these terms can be interpreted as names.
