[0045] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0046] like Figures 1 to 3As shown, this utility model embodiment provides a nest box tray 200 conveying device, including a conveying mechanism; the conveying mechanism includes two sets of synchronous belts 100 arranged in parallel and spaced apart and several trays 200. The synchronous belts 100 reciprocate in any horizontal direction, and the trays 200 are arranged in a direction perpendicular to the extension of the synchronous belts 100. One end of the tray 200 is connected to one of the synchronous belts 100, and the other end of the tray 200 is connected to the other synchronous belt 100; several trays 200 are arranged at intervals along the extension of the synchronous belts 100, and the two sides of the trays 200 are provided with edges 210 so that the nest box or tray can be locked onto the edges 210. The trays 200 and the synchronous belts 100 form alternating tray fixing grooves 410 and nest box fixing grooves 310. The tray fixing grooves 410 are configured to support the trays 400, and the nest box fixing grooves 310 are configured to support the nest boxes 300.

[0047] That is, the nest box pallet 200 conveying device provided in this embodiment of the utility model sets a pallet 200 between two sets of parallel and spaced synchronous belts 100, thereby forming a pallet fixing groove 410 and a nest box fixing groove 310 by the pallet 200 and the synchronous belt 100 surrounding the same synchronous belt 100. By adjusting the interval between the pallets 200, pallet fixing grooves 410 and nest box fixing grooves 310 of different sizes can be alternately set. When it is necessary to switch the conveying pallet or nest box, it is only necessary to adjust the distance of movement of the synchronous belt 100. This solves the technical problem that the existing nest box pallet 200 conveying device can only convey one size and model of nest box 300 or pallet 400 on the same conveying line, making it difficult to switch sizes. Adjusting the transport size requires disassembling and assembling the assembly groove, which is time-consuming and labor-intensive. This improves the conveying efficiency of columnar drug containers and thus improves the automation level of the filling production line.

[0048] Specifically, the nest box tray 200 conveying device provided by this utility model is installed in a filling production line. It mainly has a conveying mechanism, which includes two sets of synchronous belts 100 arranged parallel to each other in the horizontal direction. The synchronous belts 100 are supported by brackets and driven by servo motors. The main body of the tray 200 is an "I"-shaped flat plate, with connecting ears at both ends, which are fixed to the two synchronous belts 100 by bolts and connectors. Several trays 200 are spaced apart along the extension direction of the synchronous belts 100. Two adjacent trays 200 cooperate with the synchronous belts 100 to form a rectangular frame, namely the tray fixing groove 410 and the nest box fixing groove 310. Edges 210 are provided on both sides of the trays 200. Correspondingly, edges are also provided around the nest box 300 and the tray 400, so that the nest box 300 and the tray can overlap on the edges 210 and be placed within the rectangular frame, moving forward with the synchronous belts 100. The spacing between adjacent trays 200 varies, and the specific spacing can be set according to the size of the nest box 300 and the tray. In this embodiment, the tray fixing slot 410 and the nest box fixing slot 310 are alternately arranged; that is, a tray fixing slot 410 is followed immediately by a nest box fixing slot 310, and adjacent tray fixing slots 410 and nest box fixing slots 310 form a group. Therefore, the rectangular frame of either the tray fixing slot 410 or the nest box fixing slot 310 can be continuously transported to the desired location based on the running distance of the timing belt 100. When it is necessary to transport the nest box 300 or the tray, only the running distance of the timing belt 100 needs to be changed, thus avoiding the need to disassemble and adjust the pallet 200.

[0049] like Figure 1 and Figure 4 As shown, the nest box pallet 200 conveying device provided in this embodiment of the utility model also includes a fixed platform 500 and a pallet positioning mechanism 600; both the conveying mechanism and the pallet positioning mechanism 600 are disposed on the fixed platform 500. The conveying mechanism is divided into several production stations 510 along the extension direction of the synchronous belt 100. The pallet positioning mechanism 600 is disposed on the production station 510. The pallet positioning mechanism 600 has a clamping plate 610 that can clamp and fix the workpiece on the pallet 400.

[0050] Specifically, the fixed platform 500 is composed of a horizontal platform and a support frame, and the conveying mechanism is mounted on the horizontal platform via the support frame and bolts. Several production stations 510 are arranged along the extension direction of the synchronous belt 100, which transports the pallet 400 or the nest box 300 to the production station 510. The pallet positioning mechanism 600 has a gantry structure and is located at the production station 510. The pallet positioning mechanism 600 has two clamping plates 610, which can clamp and fix the cylindrical drug containers on the pallet 400, thereby facilitating the operation of the cylindrical drug containers by other subsequent devices.

[0051] Furthermore, the pallet positioning mechanism 600 also includes a lifting assembly 620, a horizontal moving assembly 630, and a drive assembly 640; the lifting assembly 620 is disposed on the fixed platform 500, the lifting assembly 620 has a telescopic rod 621 that moves in the vertical direction, the horizontal moving assembly 630 is connected to the top of the telescopic rod 621, the clamping plate 610 is disposed on the horizontal moving assembly 630, and the drive assembly 640 is connected to the telescopic rod 621 in a transmission manner.

[0052] Specifically, in this embodiment, there are two lifting components 620, which are respectively disposed on both sides of the conveying mechanism and bolted to the fixed platform 500. Each lifting component 620 has a telescopic rod 621 that moves vertically, and a horizontal moving component 630 is disposed horizontally perpendicular to the extension direction of the synchronous belt 100 and fixed to the top of the telescopic rod 621 by bolts. Two clamping plates 610 are driven on the horizontal moving component 630, which drives the clamping plates 610 to move closer or further apart. In this embodiment, the drive component 640 can be a pneumatic drive component 640 made of a cylinder. The cylinder is fixed to the horizontal platform by bolts, and a horizontal connecting plate is provided at the telescopic end of the cylinder. The two ends of the horizontal connecting plate are respectively connected to the bottom of the telescopic rod 621 by bolts, so that the telescopic rod 621 moves vertically through the cylinder, thereby driving the horizontal moving component 630 to rise and fall. In other embodiments of this application, the drive assembly 640 may also be configured as an electric drive assembly 640 consisting of a motor and a worm gear, or as an electric push rod.

[0053] Preferably, the lifting assembly 620 includes two fixed rods 622; the two fixed rods 622 are disposed on both sides of the conveying mechanism, and the fixed rods 622 are hollow so that the telescopic rod 621 can slide vertically on the fixed rods 622.

[0054] Specifically, the fixing rod 622 is a hollow round rod with a flange at the bottom, and is fixed vertically to the horizontal platform by bolts. The telescopic rod 621 is also a round rod, and is slidably installed in the hollow through hole of the fixing rod 622 in the vertical direction.

[0055] Preferably, the horizontal moving assembly 630 includes a platform plate 631, a moving slide rail 632, a first driving member 633, and a first slider 634; the bottom of the platform plate 631 is connected to two telescopic rods 621 respectively; the moving slide rail 632 is arranged in a horizontal direction perpendicular to the extension direction of the synchronous belt 100; the two first sliders 634 are slidably arranged on the moving slide rail 632; the two first driving members 633 are arranged opposite to each other at both ends of the moving slide rail 632; the first driving members 633 and the first sliders 634 are connected one-to-one to drive the two first sliders 634 to move closer or further away from each other; and the clamping plate 610 is fixed to the first sliders 634.

[0056] Specifically, the platform plate 631 is a rectangular platform plate 631, and the movable slide rail 632 is fixed to the platform plate 631 by bolts along a horizontal direction perpendicular to the extension direction of the synchronous belt 100. Two first driving members 633 are arranged opposite each other at both ends of the movable slide rail 632, and two first sliders 634 are arranged on the movable slide rail 632. In this embodiment, the first driving member 633 is a stepper motor, which is connected to the lead screw on the movable slide rail 632 through a coupling, thereby driving the lead screw to rotate. The first slider 634 is a nut, which is threaded onto the lead screw. The clamping plate 610 is fixed to the first slider 634 by bolts along the extension direction of the synchronous belt 100. Thus, the bolts can be moved horizontally by the first driving member 633, so that the clamping plates 610 move closer or further apart, clamping or releasing the cylindrical drug container on the support plate 200.

[0057] Preferably, the two clamping plates 610 are arranged opposite to each other, and a claw plate is detachably provided on the opposite side of the clamping plates 610, and the claw plate is provided with a plurality of grooves 611.

[0058] Specifically, the claw plate is bolted to the clamping plate 610. The claw plate has multiple evenly spaced semi-circular grooves 611, the size of which corresponds to the cylindrical drug container to be clamped. By providing grooves 611 on the clamping plate 610, the stability of the clamping plate 610 in clamping the cylindrical drug container can be effectively improved. When it is necessary to accommodate cylindrical drug containers of different sizes, the claw plate can be replaced, thereby changing the grooves 611 of different sizes to clamp the cylindrical drug container.

[0059] The pallet positioning mechanism 600 provided in this embodiment, after the pallet 400 in the pallet fixing groove 410 is transported to the production station 510, firstly, the driving component 640 drives the lifting component 620 to move the horizontal moving component 630 and the clamping plate 610 downwards to above the pallet 300, and positions the clamping plate 610 on one side of the upper end of the cylindrical drug container. Then, the first driving member 633 of the horizontal moving component 630 drives the slider to move along the moving slide rail 632, thereby bringing the two clamping plates 610 closer together and clamping the cylindrical drug container, thus fixing the cylindrical drug container on the pallet 400 and facilitating subsequent production processing.

[0060] like Figure 5 As shown, the nest box tray 200 conveying device provided in this embodiment of the utility model also includes a nest box positioning mechanism 700; the nest box positioning mechanism 700 is disposed at the production station 510, the nest box positioning mechanism 700 moves along the positioning plate 710 perpendicular to the extension direction of the synchronous belt 100, and the two nest box positioning mechanisms 700 are disposed opposite to each other on both sides of the conveying mechanism so that the two positioning plates 710 can clamp the nest box 300.

[0061] Specifically, the nest box positioning mechanism 700 is arranged at the production station 510 required for the nest box, and is arranged in the horizontal direction perpendicular to the extension direction of the synchronous belt 100. Two nest box positioning mechanisms 700 are arranged on both sides of the synchronous belt 100, and the nest box positioning mechanism 700 is fixed between the upper belt and the lower belt of the synchronous belt 100. Two positioning plates 710 are respectively arranged on the side where the two nest box positioning mechanisms 700 are close to each other, and move in the horizontal direction perpendicular to the extension direction of the synchronous belt 100, so as to clamp the nest box 300.

[0062] Furthermore, the nest box positioning mechanism 700 further includes a second driving member 720, a fixing member 730 and a sliding rod 740; the fixing member 730 is fixed to the conveying mechanism, the second driving member 720 is fixed to the conveying mechanism, the sliding rod 740 is slidably arranged in the fixing member 730 in the horizontal direction perpendicular to the extension direction of the synchronous belt 100, one end of the sliding rod 740 is in transmission connection with the second driving member 720, and the other end of the sliding rod 740 is connected to the positioning plate 710.

[0063] Specifically, the fixing member 730 is arranged in the shape of a rectangular flat plate, fixed to the horizontal platform by bolts, and arranged in the vertical direction. The second driving member 720 is fixed to the fixing member 730 by bolts in the horizontal direction perpendicular to the extension direction of the synchronous belt 100. In this embodiment, the second driving member 720 is arranged as a cylinder, a connecting plate is fixed to the telescopic end of the cylinder, and one end of the sliding rod 740 is connected to both ends of the connecting plate by bolts. The other end of the sliding rod 740 passes through the fixing member 730 and is connected to the positioning plate 710. Thus, the second driving member 720 can be used to drive the sliding rod 740 and the positioning plate 710 to approach or move away from the nest box 300, so that the positioning plate 710 can clamp the nest box 300, and further fix the columnar medicine container on the nest box 300.

[0064] Preferably, the positioning plate 710 is arranged along the extension direction of the synchronous belt 100, and stoppers 711 are arranged at both ends of the positioning plate 710, and the end portions of the stoppers 711 form an outwardly inclined bevel.

[0065] Specifically, the stopper 711 is arranged in an "L" shape and fixed to the surface of the positioning plate 710 close to the nest box 400 by bolts, so as to form an approximately "匚" shape with the positioning plate 710, and further form an approximately rectangular fixing area by the two positioning plates 710 to limit the nest box 300, ensuring the stability of clamping the nest box. There is an outwardly inclined slope at the end portion of the stopper 711, thus forming an outwardly inclined bevel. By setting the bevel, it is convenient for the nest box 300 to enter the area defined by the stopper 711, so as to limit the nest box 300. [[ID=I4]]
