Description

Technical Field

[0001] This utility model relates to the field of injection molding product processing technology, specifically to a blister box palletizing and collection device. Background Technology

[0002] In a broad sense, blister packs refer to all blister packs; in a narrow sense, they refer to only one type of blister pack: plastic boxes formed by vacuum forming from sheet material, with the lid connected to the container; they are mostly made of PS, but some have separate lids and bottoms, and different materials can be used, such as fast food boxes with black PS bottoms and transparent PET lids.

[0003] Existing methods for stacking blister boxes are mostly manual, which is labor-intensive and has low stacking efficiency. Alternatively, external stacking machines and material distribution mechanisms are used, but these are expensive. Some methods use double conveyor lines with lifting and sheeting mechanisms, but this requires a complete overhaul of the injection molding workshop's production line, which is inconvenient to implement. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a blister box palletizing and collecting device, comprising a lower platform and an upper platform. A frame and a material conveying platform are installed on the lower platform. A double-chain transmission device is installed on the frame. Multiple partitions are fixed between the double chains on the left and right sides of the double-chain transmission device. Two sets of correction and lifting components are fixed at the bottom of the upper platform, and a material transfer component is installed at the top. A stacking component is installed on the material conveying platform.

[0005] Furthermore, a side stop is formed on one side of the partition, and two sets of toothed plates are fixed on the front of the frame, with the gap between the toothed plates being able to engage with the partition.

[0006] Furthermore, the correction lifting assembly includes two positioning blocks fixed to the bottom of the upper platform. Opposing push cylinders are installed at the bottom of the positioning blocks, and opposing push plates are fixed to the piston rods of the opposing push cylinders. A top push cylinder is installed on one side of the opposing push plate, and a concave plate is fixed to the piston rod of the top push cylinder.

[0007] Furthermore, an inner block is formed on the inner side of the concave plate, and multiple suction holes are provided on both sides of the inner block.

[0008] Furthermore, the material transfer assembly includes a linear module mounted on an upper platform. The moving end of the linear module is fixed with a moving plate that slides with the upper platform. A lower-top cylinder is mounted on one side of the moving plate. The piston rod of the lower-top cylinder is fixed with a lower-top plate. Two opposing clamping cylinders are mounted on the lower-top plate. The piston rod of the clamping cylinder is fixed with a U-shaped clamping plate. Both protruding ends of the clamping plate have slots.

[0009] Furthermore, the stack top assembly includes two guide columns passing through the unloading conveyor platform, a lifting platform fixed between the tops of the two guide columns, a nut rotatably connected to the bottom of the lifting platform and a belt drive device installed thereon, one of the pulleys of the belt drive device being fixed to the bottom of the nut, and a lead screw that rotates with the bottom of the lifting platform being threaded on the inner side of the nut.

[0010] Furthermore, the top of the unloading conveyor is fixed with multiple columns, and two sliding openings are opened on one side of the lifting platform, which slide with two of the columns respectively.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] This blister box palletizing and collecting equipment uses an external conveyor to transfer products to a horizontal partition. A double-chain transmission system then moves the products upwards. A lifting and aligning component corrects the products and raises them to a height for the material transfer component to transport them to the top stacking component for palletizing. After a certain number of products are stacked, they are removed via a discharge conveyor. This significantly reduces labor intensity and equipment costs, while also offering a simpler structure and easier operation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This embodiment of a blister box palletizing and collecting device includes a lower platform 1 and an upper platform 2 located above the lower platform 1. A frame 3 is fixed on the lower platform 1, and a material conveying platform 8 is installed on the right side of the frame 3. A double-chain transmission device 4 is installed on the frame 3, so there are two sets of chains on both the left and right sides of the frame 3, and multiple equally spaced partitions 5 are fixed between the two sets of chains in the same direction. The partitions 5 are L-shaped. The upper platform 2 has a top opening, and two oppositely distributed correction lifting components 7 are installed at the bottom of the upper platform 2 and located between the left and right side chains. A material transfer component that moves at the top opening is also installed on the top of the upper platform 2. A stacking top component 9 is installed on the material conveying platform 8.

[0020] In the above structure, the injection-molded products are transferred to partitions that are distributed horizontally on the same level by an external conveying device. The products are then driven upward by a double-chain transmission device until they are between two corrective lifting components, thus completing the product position correction. At the same time, the products are also lifted to a certain distance, making it easier for the transfer component to grab the products and place them in the stacking component for stacking. Once a certain amount has been placed, the products are transferred to the unloading conveyor for collection. Therefore, it can reduce labor and costs, and the structure is simple and easy to operate.

[0021] The partition 5 has a side guard on its back, and the frame 3 has two toothed plates 6 fixed on its front, opposite to the partition 5. The toothed plates 6 have gaps between their teeth, which can connect with the two partitions 5 on the same horizontal line. Therefore, they can connect with external conveying devices at different heights through the gaps in the toothed plates. The gaps in the toothed plates guide the product to be placed on the partition. Simultaneously, when the double-chain drive moves the partition, each time it moves a distance, the partition opposite the toothed plate can connect with the corresponding gap. During placement, the product is moved until it is in contact with the side guard, thus confirming successful product conveying. The side guard acts as a limit, and the double-chain drive then drives the product upwards.

[0022] like Figure 3The lifting and correcting assembly includes two opposing positioning blocks 701 fixed to the bottom of the upper platform 2. A counter-push cylinder 702 is installed at the bottom of each positioning block 701. A counter-push plate 703 is fixed to the piston rod of the counter-push cylinder 702. A top-push cylinder 704 is installed on one side of each of the two counter-push plates 703. A concave plate 705 is fixed to the piston rod of each top-push cylinder 704, with the concave surfaces of the two concave plates facing each other. When the double-chain transmission device progressively moves the product to the moving height via the partition and positions it between the two concave plates, the operation of the two sets of counter-push cylinders allows the product's sides to be positioned within the concave plates. Simultaneously, the product's position is corrected by the counter-push action. Furthermore, the top-push cylinders push the product away from the partition via the concave plates and lift it to the moving height for easy access by the material transfer assembly.

[0023] The inner sides of both concave plates 705 have inner blocks 706, and two suction holes 707 are opened on the left and right sides of the inner blocks 706. One end of the suction hole 707 is connected to an external adsorption device. The inner blocks can extend into the two concave surfaces of the product, thereby guiding and limiting the product. When the product comes into close contact with the concave plates, the external adsorption device and the suction holes can adsorb and fix the product, improving the stability during the transfer process.

[0024] like Figure 2 The material transfer assembly includes a linear module 11 mounted on the upper platform 2. The moving end of the linear module 11 is fixed with a moving plate 12 that slides with the upper platform 2. A lower top cylinder 13 is mounted on the front of the moving plate 12. A lower top plate 14 is fixed to the piston rod of the lower top cylinder 13. A clamping cylinder 15 located on the left and right sides of the lower top cylinder 13 is fixed to the top of the lower top plate 14. The piston rods of the clamping cylinders 15 are opposite to each other, and clamping plates 16 are fixed on the piston rods. The clamping plates 16 are U-shaped, and the opposite protruding ends are provided with slots. The concave plate 705 is adapted to the concave surface of the clamping plate 16. After the concave plate lifts the product to a certain height, the lower top cylinder drives the lower top plate to move down. After moving down to a certain height, the product is positioned between the two clamping plates. Then, the clamping cylinder drives the two clamping plates to move relative to each other, so that the product is just positioned in the concave surface. After clamping, the product is reset. The linear module then moves the product above the stack top component and places it on the moving plate, completing the product transfer.

[0025] like Figure 4The stacking top assembly 9 includes two guide posts 901 passing through the unloading conveyor table 8. A lifting platform 902 is fixed between the tops of the two guide posts 901. A lead screw 903 is rotatably connected to the bottom of the lifting platform 902. A nut 904 is threaded onto the outer side of the lead screw 903. The nut 904 is rotatably connected to the bottom of the lifting platform 902. A belt drive device 905 is installed at the bottom of the unloading conveyor table 8. One of the pulleys of the belt drive device 905 is fixed to the nut 904. The guide posts limit the lifting platform. With the belt drive device driving the nut to rotate, the lead screw can be adjusted to lift and lower. Therefore, in the initial state, the lead screw will drive the lifting platform to rise, and then gradually move down until it moves to the inside of the unloading conveyor table, so that the bottom of the stacked products contacts the unloading conveyor table. Thus, the stacked products can be removed by the unloading conveyor table.

[0026] The unloading conveyor platform 8 has six fixed columns 10 on its surface, arranged in a U-shape around the outside of the lifting platform 905. Two sliding openings are located on the right side of the lifting platform 905, allowing sliding contact with two of the columns 10. This cooperation between the sliding openings and the columns improves the stability of the lifting platform's vertical movement and also limits the product's position during descent and placement, preventing it from shifting or falling.

[0027] The working principle of the above embodiments is as follows:

[0028] The product is guided by a toothed plate and placed on a partition by an external conveying device. Then, a double-chain transmission device operates, moving the product upwards. After reaching a designated height, a push cylinder operates, using a concave plate to correct the product's position and using inner blocks and suction holes to enhance the stability of the product's movement. Then, a push cylinder operates, moving the product to a suitable height. A lower push cylinder then moves the clamping plates downwards until the product is between the clamping plates. A clamping cylinder operates, clamping the product with the clamping plates. Then, in conjunction with a linear module, the product is transferred to a lifting platform. During placement, the uprights guide and limit the product. Then, a belt drive device drives a nut to rotate, causing the lead screw to move downwards, thus gradually lowering the lifting platform until the bottom of the stacked product contacts the unloading conveyor and is sent away.

[0029] In summary, it greatly reduces labor intensity and equipment costs, while also having a simpler structure and being easier to execute.
