Description

Technical Field

[0001] This utility model relates to the field of test tube production technology, specifically to a test tube tray transfer device. Background Technology

[0002] After the test tubes are produced and labeled, they need to be transferred to the next production node for sorting, stacking, and storage. Since the test tubes are cylindrical, they are likely to roll on the conveyor belt during the transfer process. Furthermore, the outer diameter of the cap of the test tube is generally larger than the outer diameter of the tube body, which will further cause the rolling path to bend. As a result, the test tubes cannot be evenly distributed on the conveyor belt, or may even roll off the conveyor belt.

[0003] To avoid the above situation and to classify and stack the test tubes, trays are generally placed on the conveyor belt so that the trays move synchronously along the conveyor belt. Then, the test tubes are classified and placed in the trays, which can limit the position of the test tubes.

[0004] To accommodate the shape of test tubes, trays used for stacking test tubes are generally rectangular. Because their side length needs to match the length of the test tubes, the horizontal area of ​​the trays is generally large. To make full use of space, when providing and collecting trays for storage, the trays are generally arranged vertically above the conveyor belt. Therefore, when providing trays, they are placed from top to bottom, and when collecting trays, the trays containing test tubes need to be taken to the upper tray stacking area. Existing tray conveying devices generally cannot do this operation, and the trays need to be transferred by manual assistance. Moreover, because the tray openings are generally large, it is not only inconvenient to grab the tray from above, but it is also very easy to cause the tray to tilt, and in severe cases, even cause the test tubes inside the tray to fall out.

[0005] Therefore, this application is hereby submitted. Summary of the Invention

[0006] The purpose of this invention is to provide a test tube tray conveying device to solve the problem that the tray cannot be smoothly returned to the tray stacking position after being filled with test tubes.

[0012] In another preferred embodiment, the bottoms of the two baffles are fixedly connected by two beam plates.

[0013] In another preferred embodiment, the conveyor belt includes a tube-picking conveyor belt and a buffer conveyor belt, which are linearly arranged.

The buffer conveyor belt is positioned at the end of the buffer conveyor belt away from the tube-picking conveyor belt, and the tube-picking conveyor belt is connected to each other close to each other so that the tray can be conveyed from the tray-receiving position to the lifting position.

[0014] In another preferred embodiment, the two tube-taking conveyor belts are connected by a first drive shaft located directly above a beam plate. The first drive shaft is connected to a first drive motor, which is fixedly connected to the beam plate.

[0015] In another preferred embodiment, the two buffer conveyor belts are connected by a second drive shaft located directly above another beam plate. The second drive shaft is connected to a second drive motor, which is fixedly connected to the beam plate.

[0016] In another preferred embodiment, the conveying speed of the buffer conveyor belt is greater than the conveying speed of the tube-taking conveyor belt.

Through the coordination of these features, this test tube tray transport device effectively solves the problem of trays not smoothly returning to the designated height for tray stacking after being filled with test tubes.

[0022] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane". Example

[0023] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a test tube tray transport device, including: a pair of conveyor belts 50, the two conveyor belts 50 being arranged in parallel and spaced apart to form a lifting gap between the two conveyor belts 50, the two ends of each conveyor belt 50 being respectively provided with a tube loading position 501 and a lifting position 502, the conveyor belt 50 being provided with a tray receiving position 503, the tray receiving position 503 being located between the tube loading position 501 and the lifting position 502; and a second component including a lifting mechanism, the lifting mechanism being provided at the lifting position 502, the lifting mechanism being provided with a lifting platform 51, the lifting platform 51 being located within the lifting gap and directly below the lifting position 502, the lifting platform 51 being used to lift the tray containing test tubes to a storage position, so that the tray is separated from the conveyor belts 50.

[0024] The test tube tray conveying device disclosed in this embodiment uses a pair of conveyor belts 50 arranged parallel to each other to form a lifting gap. A lifting mechanism with a lifting platform 51 is provided between the two lifting gaps, allowing the lifting platform 51 to smoothly lift the tray from bottom to top to a set height for tray stacking. The conveyor belts 50 include a tube loading position 501, a lifting position 502, and a receiving position 503. In use, the tray is placed from top to bottom at the receiving position 503 and then conveyed by the conveyor belts. The pallet is conveyed to the tube loading position 501, where test tubes are placed into the pallet. The pallet containing the test tubes is then conveyed to the lifting position 502 via the conveyor belt 50. The lifting platform 51 smoothly lifts the pallet containing the test tubes from bottom to top to the set height of the pallet stacking area. The pallet is then removed and sorted and stacked. Through the cooperation of the above features, the test tube pallet conveying device can effectively solve the problem that the pallet cannot smoothly return to the set height of the pallet stacking area after being filled with test tubes.

[0025] It should be noted that, Figure 1 In order to make it easier to intuitively show the specific positions of the pipe loading position 501, the lifting position 502 and the receiving position 503, a tray is drawn at each of the three positions, so that the specific position of the three can be indicated by the specific position of the tray.

[0026] To further explain the specific structure of the lifting mechanism, the lifting mechanism includes a lifting motor 52, a lifting screw 53, and a fixing frame 54; the fixing frame 54 is fixedly connected to the base frame of the side wall of the conveyor belt 50; the lifting motor 52 is detachably connected to the fixing frame 54; the lifting screw 53 is drivenly connected to the lifting motor 52, and the lifting screw 53 is vertically arranged; the lifting platform 51 is screwed to the lifting screw 53, and the lifting platform 51 and the fixing frame 54 are slidably connected through a plurality of sliding rods 511, and the sliding rods 511 are arranged parallel to the lifting screw 53.

[0027] With the above settings, the lifting motor 52 drives the lifting screw 53 to rotate in a directional manner, which can drive the lifting platform 51 connected to it to rise or fall; by setting the slide bar 511, the rotation limit of the lifting platform 51 is set so that it can only rise and fall, but cannot rotate.

[0028] To further explain the specific structure of the lifting platform 51, the lifting platform 51 includes a lifting plate 512 and a support plate 513. The lifting plate 512 and the support plate 513 are spaced apart and fixedly connected by multiple fixing rods 514. The fixing rods 514 are arranged parallel to the lifting screw 53. The middle part of the lifting plate 512 is screwed to the lifting screw 53. The support plate 513 is located directly above the lifting plate 512, and the top surface of the support plate 513 is used to support the tray.

[0029] With the above configuration, the lifting screw 53 can be screwed into the middle of the lifting plate 512 to improve the force balance of the lifting plate 512 and the support plate 513 during the lifting process, thereby improving the stability of both.

[0030] To prevent the pallet from slipping off the sides of the conveyor belt 50, the outer side wall of the conveyor belt 50 is vertically provided with baffles 55, the top of the baffles 55 is set at a height higher than the top surface of the conveyor belt 50; the distance between the two baffles 55 is slightly larger than the size of the pallet.

[0031] To position the pallet, the upper inner sides of the two baffles 55 are symmetrically provided with a first positioning stop 551 and a second positioning stop 552, respectively; when the pallet is in contact with the two first positioning stops 551, the pallet is located in the tube loading position 501; when the pallet is in contact with the two second positioning stops 552, the pallet is located in the lifting position 502.

[0032] With the above settings, on the one hand, the pallet can be accurately positioned to ensure that it is in the tube loading position 501 or the lifting position 502; on the other hand, the conveyor belt 50 can continuously convey the pallet. After the pallet is blocked by the first positioning bar 551 or the second positioning bar 552, it can slide relative to the conveyor belt 50, and it can still be ensured that it is in the tube loading position 501 or the lifting position 502.

[0033] To further enhance structural stability and integrity, the bottoms of the two baffles 55 are fixedly connected by two beams 553.

[0034] To further optimize the specific structure of the conveyor belt 50, the conveyor belt 50 includes a tube-picking conveyor belt 504 and a buffer conveyor belt 505. The tube-picking conveyor belt 504 and the buffer conveyor belt 505 are linearly arranged. The tube loading position 501 is set at the end of the tube-picking conveyor belt 504 away from the buffer conveyor belt 505, and the receiving position 503 is set at the end of the tube-picking conveyor belt 504 close to the buffer conveyor belt 505. The lifting position 502 is set at the end of the buffer conveyor belt 505 away from the tube-picking conveyor belt 504. The tube-picking conveyor belt 504 and the buffer conveyor belt 505 are arranged close to each other and connected so that the tray can be conveyed from the receiving position 503 to the lifting position 502.

[0035] To ensure the synchronization of the two pipe-retrieving conveyor belts 504, the two pipe-retrieving conveyor belts 504 are connected by a first drive shaft 56. The first drive shaft 56 is located directly above a beam plate 553. The first drive shaft 56 is connected to a first drive motor (not shown in the figure), and the first drive motor is fixedly connected to the beam plate 553.

[0036] To ensure the synchronization of the two buffer conveyor belts 505, the two buffer conveyor belts 505 are connected by a second drive shaft 57. The second drive shaft 57 is located directly above another beam plate 553. The second drive shaft 57 is connected to a second drive motor (not shown in the figure), and the second drive motor is fixedly connected to the beam plate 553.

[0037] Preferably, the conveying speed of the buffer conveyor belt 505 is greater than the conveying speed of the tube-taking conveyor belt 504.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
