Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical packaging machinery, and particularly to an unpacking machine. Background Art

[0002] In the field of aseptic syringe filling, syringes are generally placed in a nest box, and an outer packaging bag is sleeved outside the nest box. Before the nest box is taken out, the outer packaging bag needs to be removed. The removal process should be as airtight as possible to ensure the sterility of the nest box. There are one-step and two-step methods for removing the outer packaging bag. The one-step method cuts the bag head and pushes out the nest box at the same station, increasing the risk of aseptic control. The two-step method cuts the bag head in a sealed state and then pushes out the nest box at the second station. The nest box is directly pushed into the environment of another device without being exposed inside the unpacking machine. Therefore, the two-step method better meets the requirements of the aseptic syringe filling process.

[0003] Publication Document 1, Chinese Patent (CN212862180U), a pre-filled syringe outer packaging removing machine, includes a conveying track, a cutting mechanism, an outer packaging bag guiding mechanism, and a bag pressing mechanism arranged in sequence along the conveying direction of the conveying track. The cutting mechanism is arranged on one side of the conveying track, and the outer packaging bag guiding mechanism and the bag pressing mechanism are arranged on the other side of the conveying track, and the outer packaging bag guiding mechanism and the bag pressing mechanism are docked. The pre-filled syringe outer packaging removing machine adopts the two-step method and has two stations. The cutting mechanism first cuts off the front end of the outer packaging bag, and then uses the outer packaging bag guiding mechanism to correct the rear end of the outer packaging bag. The corrected outer packaging bag is conveyed to the bag pressing mechanism.

[0004] For the pre-filled syringe outer packaging removing machine in Publication Document 1, before the cutting mechanism cuts off the outer packaging bag, the outer packaging bag is not pre-organized. During the packing and boxing process of the outer packaging bag, wrinkles will occur, so the shape of the outer packaging is irregular. Without a pre-organization process, when cutting the outer packaging bag, it cannot be ensured that the pressing mechanism accurately presses the front end of the outer packaging bag. Secondly, the cutting mechanism first cuts off the front end of the outer packaging bag, and then uses the outer packaging bag guiding mechanism to correct the rear end of the outer packaging bag. After the corrected outer packaging bag is conveyed to the bag pressing mechanism, when the cutting mechanism cuts off the front end of the outer packaging bag, the honeycomb box has already tilted. Without other auxiliary guiding devices, only by using the outer packaging bag guiding mechanism to correct the rear end of the outer packaging bag, it cannot be ensured that the honeycomb box is accurately guided. Then, there is a pressing mechanism above the cutting mechanism, and a single pressing mechanism cannot ensure the success rate of cutting. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art, and provides an unpacking machine, which realizes the pre-organization of the outer packaging bag, prevents the honeycomb box from tilting during the cutting of the outer packaging bag, and ensures the success rate of cutting.

[0006] The present invention provides an unpacking machine, which includes an unpacking mechanism, a nest box pushing mechanism, and a supporting mechanism. The unpacking mechanism and the nest box pushing mechanism are located on the supporting mechanism, and the nest box pushing mechanism is located on the output side of the unpacking mechanism.

[0007] The unpacking mechanism includes a conveyor line, a nest box outer bag sorting component, a bag cutting head component, and an opposite side pressing component. The nest box outer bag sorting component and the bag cutting head component are sequentially arranged on one side of the conveyor line, and the opposite side pressing component is arranged corresponding to the bag cutting head component on the other side of the conveyor line. The nest box pushing mechanism is arranged at the end of the conveyor line.

[0008] The bag cutting head component includes a cutting knife. Pressing upper tooth plates and pressing rollers are arranged in parallel on both opposite sides of the cutting knife, and pressing lower tooth plates are arranged staggered corresponding to the pressing upper tooth plates. The end of the nest box outer bag is pressed by the pressing roller, the pressing upper tooth plate presses downwards and intersects with the pressing lower tooth plate to tightly press the inner side of the outer bag, ensuring that the contact surface between the cutting knife and the nest box outer bag forms a cross shape, and the cutting success rate is high.

[0009] The conveyor line includes a conveying track. A conveyor belt is arranged on the conveying track, and conveying stoppers are evenly distributed on the conveyor belt. Conveying guide shafts are arranged corresponding to the nest box on the conveying track. The conveyor belt can adopt a single - root centered design, and there are 4 guide shafts on both sides to prevent the nest box from skewing during transportation.

[0010] The opposite side pressing component includes a pressing plate. The pressing plate is installed on the frame component through an adjusting column, and a detection device is arranged corresponding to the nest box on the pressing plate. When the cutting knife cuts the end of the nest box outer bag, the pressing plate assists in pressing the outer side of the nest box, effectively preventing the nest box from tilting up. The adjusting column can adjust the height of the pressing plate so that the pressing plate can match nest boxes of different heights. The detection device is used to detect whether the nest box reaches a predetermined position.

[0011] The nest box outer bag sorting component includes a sorting top plate and a sorting bottom plate, and the sorting top plate and the sorting bottom plate are arranged in a V - shape. During the packing and boxing process of the nest box outer bag, wrinkles will be generated, so the outer packaging shape is irregular. The V - shaped cavity formed by the sorting top plate and the sorting bottom plate can pre - sort the shape of the nest box outer bag.

[0012] The nest box pushing mechanism includes a nest box pushing component. The nest box pushing component is located at the end of the conveyor line, and a partition component is arranged along the pushing direction of the nest box pushing component. When the nest box is pushed out from the nest box outer bag, the nest box can directly reach the outside of the partition, and the nest box will not be exposed to the environment of the unpacking machine.

[0013] The nest box pushing component includes a pushing bottom plate. The pushing bottom plate is slidably connected to the supporting mechanism through a support frame. A lower adsorption device is arranged on the pushing bottom plate, and an upper adsorption device is arranged corresponding to the lower adsorption device. The upper adsorption device is slidably connected to the support frame through a lifting frame. The lower adsorption device and the upper adsorption device are used to adsorb the nest box outer bag to prevent the nest box outer bag from being pushed out together with the nest box.

[0014] A push rod is slidably arranged on the described support frame corresponding to the nest box, and a horizontal adsorption device is arranged on the side of the push rod close to the nest box. The horizontal adsorption device adsorbs the outer packaging bag of the nest box, and the push rod pushes the nest box out of the outer packaging bag of the nest box.

[0015] The described partition component includes a support frame, a partition board is slidably arranged on the support frame corresponding to the nest box, and rollers are arranged on the support frame corresponding to the output side of the push-out bottom plate. The partition board separates the unpacking of the nest box from the next operation, realizing the sterile transfer of the nest box.

[0016] The described support mechanism includes an equipment table board, a pressing plate is installed on the equipment table board through an adjusting column, the push-out bottom plate is slidably connected to the equipment table board through a support frame, and a waste bag bin is arranged below the equipment table board. The waste bag bin is used to hold the outer packaging bag of the nest box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting the outer packaging bag sorting component, the bag cutting head component and the opposite side pressing component, the present invention realizes the pre-sorting of the outer packaging bag, prevents the nest box from tilting when the outer packaging bag is cut, and ensures the success rate of cutting.

[0019] 2. The bag cutting head component includes a cutting knife, a bag pressing upper tooth plate and a pressing roller are arranged in parallel on both opposite sides of the cutting knife, and a bag pressing lower tooth plate is arranged in an interleaved manner corresponding to the bag pressing upper tooth plate. The end of the outer packaging bag of the nest box is pressed by the pressing roller, the bag pressing upper tooth plate presses down, and is interleaved with the bag pressing lower tooth plate to press the inner side of the outer packaging bag, ensuring that the contact surface between the cutting knife and the outer packaging bag of the nest box is in a cross shape, and the cutting success rate is high.

[0020] 3. The opposite side pressing component includes a pressing plate, the pressing plate is installed on the frame component through an adjusting column, and a detection device is arranged on the pressing plate corresponding to the nest box. When the cutting knife cuts the end of the outer packaging bag of the nest box, the pressing plate effectively prevents the nest box from tilting. BRIEF DESCRIPTION OF THE DRAWINGS
