Description

Technical Field

[0001] The utility model relates to the technical field of heat sealing, in particular to a manual bagging vacuum heat sealing device and a container nesting bagging production line. Background Art

[0002] The prior art discloses a sterilization method in an isolator, such as an isolator and a hydrogen peroxide gas sterilization method with patent number: CN202011003609.6. By controlling the concentration of hydrogen peroxide gas, the reliability of the hydrogen peroxide gas sterilization process can be enhanced.

[0003] In the nuclear medicine field, after the bottles are placed in the nest, the nest box needs to be vacuum heat-sealed so that they can be aseptically transferred to the next process. In the actual working process, burns from the heat sealing mechanism often occur, and the use of the heat sealing device raises safety issues. Utility Model Content

[0004] The purpose of the utility model is to provide a manual bagging vacuum heat sealing device and a container nesting bagging production line, which solves the problem of being scalded by the heat sealing mechanism frequently occurring in the actual working process and the safety problem of using the heat sealing device.

[0005] The utility model is implemented as follows: a manual bagging vacuum heat sealing device comprises a material conveying mechanism, a bagging platform, a vacuum pumping mechanism, a placement platform for placing the vacuum pumping mechanism, an openable and closable pre-pressing and heat sealing mechanism, and a control button for controlling the opening and closing of the pre-pressing and heat sealing mechanism, wherein the control button comprises a first button and a second button which are spaced apart and connected in series.

[0006] The material is transported to the material taking position through the conveying mechanism, and the material is manually transferred from the conveying mechanism to the bagging platform for bagging through gloves outside the isolator, and then put back to the material conveying mechanism, and the bag outside the material is vacuumed. After the vacuuming is completed, the vacuuming mechanism is returned to the placement platform. The first button and the second button are set at a distance, and one hand cannot press them at the same time. Both hands are required to press the two buttons separately. At the same time, because the first button and the second button are connected in series, pressing one button with one hand cannot activate the pre-pressing heat sealing mechanism; in summary, it can be seen that the pre-pressing heat sealing mechanism will only start to act when both hands press the first button and the second button, thereby avoiding the risk of fingers being clamped by the pre-pressing heat sealing mechanism during the use of the utility model, ensuring the safety of the operator, and preventing safety risks caused by workers' misoperation.

[0007] A further technical solution of the utility model is that: an induction switch for controlling the start and stop of the vacuum pumping mechanism is arranged on the placement platform.

[0008] Before using the vacuum mechanism, the vacuum mechanism is placed on the placement platform. After the bagged material is placed back on the material conveying mechanism, the bag opening is arranged to be placed between the open and closed ends of the pre-pressing heat sealing mechanism. When the vacuum mechanism is taken down from the placement platform, the induction switch senses the action and starts the vacuum mechanism. The vacuum mechanism is placed at the bag opening of the pre-pressing heat sealing mechanism to vacuum the bag. In this process, the vacuum mechanism can be started without pressing a button. After vacuuming, the vacuum mechanism is placed back on the placement platform, and the vacuum function is turned off after the induction switch senses the vacuum mechanism.

[0009] A further technical solution of the utility model is that: the placing platform is provided with an induction switch for controlling the heat sealing of the pre-pressing heat sealing mechanism.

[0010] After the vacuuming is completed, the vacuuming mechanism is placed back on the placement platform. After the induction switch detects that the vacuuming mechanism is placed on the placement platform, the vacuuming mechanism is turned off and the pre-pressing heat sealing mechanism is started to perform heat sealing. After the heat sealing action is started, the heat sealing is automatically stopped within the set time to complete the heat sealing of the bag mouth. The heat sealing action of the pre-pressing heat sealing mechanism does not require other buttons to control, reducing the difficulty of operation.

[0011] A further technical solution of the utility model is that: the material conveying mechanism is provided with a lifting mechanism for separating the material from and placing the material on the material conveying mechanism.

[0012] When the material is transported to the top of the lifting mechanism, the lifting mechanism will push the material out, making it convenient for manual labor to take the material to the bagging platform. After the bagging is completed, the bagged material is returned to the material conveying mechanism through the lifting mechanism. This process is convenient for manual operation.

[0013] A further technical solution of the utility model is: the first button and the second button are placed on both sides of the bagging platform.

[0014] When the staff uses the device of the utility model, they put on the bag facing the bagging platform for easy operation. The first button and the second button are arranged on both sides of the bagging platform, which is convenient for the staff to operate with both hands.

[0015] A further technical solution of the utility model is: the vacuuming mechanism comprises a vacuum pump and a vacuum suction nozzle connected to the vacuum pump, and the vacuum suction nozzle is detachable and placed on the placement platform.

[0016] The start and stop of the vacuum pump is controlled by the induction switch installed on the placement platform. Specifically, the induction switch detects the position of the vacuum nozzle, which can automatically open and close the vacuum pumping mechanism and start the heat sealing action of the pre-pressing heat sealing mechanism. After the heat sealing action is started, the heat sealing will automatically stop within the set time.

[0017] A further technical solution of the utility model is that the placing platform is placed on the side of the pre-pressing heat sealing mechanism.

[0018] The placement platform is used to place the vacuum nozzle of the vacuum extraction mechanism, and is convenient for staff to take and place it on the side of the pre-pressing heat sealing mechanism.

[0019] A further technical solution of the utility model is that the pre-pressing heat sealing mechanism comprises a heat sealing block and a pre-pressing block arranged up and down, a heat sealing driving mechanism for driving the heat sealing block to move, and a pre-pressing driving mechanism for driving the pre-pressing block to move.

[0020] The pre-pressing driving mechanism is used to drive the pre-pressing pressing block to pre-press the vacuum bag opening to facilitate vacuuming; after the vacuuming is completed, the vacuum suction nozzle is placed back on the placement platform, and the heat sealing driving mechanism is controlled by the induction switch on the placement platform to drive the heat sealing pressing block to seal the bag opening.

[0021] A further technical solution of the utility model is: the heat sealing block and the pre-pressing block are both connected to the lifting member, the lifting member is connected to the pre-pressing driving mechanism, and the heat sealing driving mechanism is connected to the pre-pressing driving mechanism.

[0022] Before heat sealing, pre-pressing is required to facilitate vacuuming. The working process of the utility model is as follows: after pressing the first button and the second button, the pre-pressing drive mechanism starts, driving the lifting member to descend, and the upper and lower pre-pressing blocks are close to each other, and the bag mouth with the vacuum nozzle is pre-pressed to ensure the vacuuming effect. After the vacuuming is completed, the vacuum nozzle is taken out of the bag mouth and put back on the placement platform. After the induction switch on the placement platform senses that the vacuum nozzle has returned to its position, the heat sealing drive mechanism is controlled to drive the pre-pressing drive mechanism to descend and drive the lifting member to descend further, and the heat sealing blocks are closer to each other for heat sealing. After the heat sealing set time, it automatically closes to complete the heat sealing.

[0023] A further technical solution of the utility model is that a spring is provided on the pre-pressing block.

[0024] The design of the spring provides a certain buffer space for the pre-compression block, which will not cause damage to the vacuum nozzle; and the bag opening can be compressed when vacuuming.

[0025] The present invention also provides a container nesting and bagging production line, comprising a container conveyor line, a nest box conveyor line, a container nesting mechanism, the heat sealing device and a buffer station, wherein the container conveyor line and the nest box conveyor line are vertically arranged on a horizontal plane, the container nesting mechanism is used to place containers on the container conveyor line into nest boxes of the nest box conveyor line, the heat sealing device is used to bag and heat seal nest boxes containing containers, and the buffer station is used to cache the nest boxes after bagging and heat sealing.

[0026] The container is transported to the material taking place of the container nesting mechanism through the container conveyor line, and the empty nest box is transported to the place for receiving the container through the nesting box conveyor line. The container is placed into the empty nest box through the container nesting mechanism to complete the nesting of the container; the nest box with the container enters the manual bagging vacuum heat sealing device to bag and heat seal the nest box, and the heat-sealed nest box enters the nest box buffer station for buffering.

[0027] The container conveyor line and the nest box conveyor line are vertically arranged on a horizontal plane. A container nesting mechanism is provided at the intersection of the container conveyor line and the nest box conveyor line to facilitate placing the container into the nest box. The space design is reasonable and the operation is convenient.

[0028] The beneficial effects of the utility model are as follows: the material is transported to the material taking position through the conveying mechanism, and the material is manually transferred from the conveying mechanism to the bagging platform for bagging through the gloves outside the isolator, and then put back to the material conveying mechanism, and the bag outside the material is vacuumed. After the vacuuming is completed, the vacuuming mechanism is put back on the placement platform, and the first button and the second button are set at a distance, and one hand cannot press them at the same time, and both hands are required to press the two buttons separately. At the same time, because the first button and the second button are connected in series, pressing one button with one hand cannot activate the pre-pressing heat sealing mechanism; in summary, it can be seen that the pre-pressing heat sealing mechanism will only start to act when both hands press the first button and the second button, thereby avoiding the risk of fingers being clamped by the pre-pressing heat sealing mechanism during the use of the utility model, ensuring the safety of the operator, and preventing safety risks caused by workers' misoperation.

[0038] Embodiment 1:

[0039] Figure 1-5 A manual bagging vacuum heat sealing device is shown, comprising a material conveying mechanism 1, a bagging platform 2, a vacuum pumping mechanism, a placement platform 4 for placing the vacuum pumping mechanism, an openable and closable pre-pressing heat sealing mechanism 5, and a control button for controlling the opening and closing of the pre-pressing heat sealing mechanism 5, wherein the control button comprises a first button 6 and a second button 7 which are arranged at a distance and connected in series.

[0040] In this embodiment, the placement platform 4 is provided with an induction switch for controlling the start and stop of the vacuum mechanism.

[0041] Before using the vacuum mechanism, the vacuum mechanism is placed on the placement platform. After the bagged material is placed back on the material conveying mechanism, the bag opening is arranged to be placed between the open and closed ends of the pre-pressing heat sealing mechanism. When the vacuum mechanism is taken down from the placement platform, the induction switch senses the action and starts the vacuum mechanism. The vacuum mechanism is placed at the bag opening of the pre-pressing heat sealing mechanism to vacuum the bag. In this process, the vacuum mechanism can be started without pressing a button. After vacuuming, the vacuum mechanism is placed back on the placement platform, and the vacuum function is turned off after the induction switch senses the vacuum mechanism.

[0042] In this embodiment, after the vacuuming mechanism is taken from the placement platform and placed at the bag opening, the first button and the second button are pressed to allow the pre-pressing heat sealing mechanism to pre-press the bag opening to ensure the vacuuming effect.

[0043] In this embodiment, a mounting seat for mounting a vacuum nozzle of a vacuum extraction mechanism is provided on the side of the bagging platform.

[0044] In this embodiment, the placement platform 4 is provided with an induction switch for controlling the heat sealing of the pre-pressing heat sealing mechanism 5 .

[0045] After the vacuuming is completed, the vacuuming mechanism is placed back on the placement platform. After the induction switch detects that the vacuuming mechanism is placed on the placement platform, the vacuuming mechanism is turned off and the pre-pressing heat sealing mechanism is started to perform heat sealing. After the heat sealing action is started, the heat sealing is automatically stopped within the set time to complete the heat sealing of the bag mouth. The heat sealing action of the pre-pressing heat sealing mechanism does not require other buttons to control, reducing the difficulty of operation.

[0046] In this embodiment, the induction switch used to control the heat sealing of the pre-pressing heat sealing mechanism and the induction switch used to control the start and stop of the vacuuming mechanism are the same induction switch.

[0047] In this embodiment, the material conveying mechanism 1 is provided with a lifting mechanism 11 for separating materials from and placing them on the material conveying mechanism 1 .

[0048] When the material is transported to the top of the lifting mechanism, the lifting mechanism will push the material out, making it convenient for manual labor to take the material to the bagging platform. After the bagging is completed, the bagged material is returned to the material conveying mechanism through the lifting mechanism. This process is convenient for manual operation.

[0049] In this embodiment, the pre-pressing heat sealing mechanism is placed between the material conveying mechanism and the bagging platform, and the top of the pre-pressing heat sealing mechanism is higher than the material conveying mechanism. Manual operation is performed by standing on one side of the bagging platform. After the lifting mechanism pushes the material out of the material conveying mechanism, it is convenient for manual operation to take the material to the bagging platform.

[0050] In this embodiment, a photoelectric switch 12 is provided on the lifting mechanism. After the photoelectric switch 12 detects that the material has left after the heat sealing is completed, the lifting mechanism extends to block and position the next material.

[0051] In this embodiment, the material conveying mechanism includes two parallel conveyor belts, and the lifting mechanism is placed between the conveyor belts. The lifting mechanism can lift the material on the conveyor belt when it rises, and can place the material on the conveyor belt when it descends. The conveyor belt continues to move to transport the heat-sealed material to the next process.

[0052] In this embodiment, the first button 6 and the second button 7 are placed on both sides of the bagging platform 2 .

[0053] When the staff uses the device of the utility model, they put on the bag facing the bagging platform for easy operation. The first button and the second button are arranged on both sides of the bagging platform, which is convenient for the staff to operate with both hands.

[0054] In this embodiment, the first button and the second button are fixedly connected to the bagging platform.

[0055] In this embodiment, the vacuum extraction mechanism includes a vacuum pump and a vacuum suction nozzle 31 connected to the vacuum pump. The vacuum suction nozzle 31 is detachable and can be placed on the placement platform 4 .

[0056] The start and stop of the vacuum pump is controlled by the induction switch installed on the placement platform. Specifically, the induction switch detects the position of the vacuum nozzle, which can automatically open and close the vacuum pumping mechanism and start the heat sealing action of the pre-pressing heat sealing mechanism. After the heat sealing action is started, the heat sealing will automatically stop within the set time.

[0057] In this embodiment, the vacuum pump is connected to the vacuum nozzle through a vacuum tube. A mounting seat for placing the vacuum nozzle is provided on the bagging platform near the pre-pressing heat sealing mechanism, so as to facilitate the vacuum nozzle to be aligned with the bag opening for vacuuming.

[0058] As another embodiment, a photoelectric detection switch is provided on the mounting seat, and the photoelectric detection switch is used to control the start and stop of the vacuum pumping mechanism.

[0059] In this embodiment, the placement platform 4 is placed on the side of the pre-pressing heat-sealing mechanism 5 .

[0060] The placement platform is used to place the vacuum nozzle of the vacuum extraction mechanism, and is convenient for staff to take and place it on the side of the pre-pressing heat sealing mechanism.

[0061] In this embodiment, the pre-pressing heat sealing mechanism 5 includes a heat sealing block 51 and a pre-pressing block 91 arranged up and down, a heat sealing driving mechanism 52 for driving the heat sealing block 51 to move, and a pre-pressing driving mechanism 92 for driving the pre-pressing block 91 to move.

[0062] The pre-pressing driving mechanism is used to drive the pre-pressing pressing block to pre-press the vacuum bag opening to facilitate vacuuming; after the vacuuming is completed, the vacuum suction nozzle is placed back on the placement platform, and the heat sealing driving mechanism is controlled by the induction switch on the placement platform to drive the heat sealing pressing block to seal the bag opening.

[0063] In this embodiment, the heat sealing block 51 and the pre-pressing block 91 are both connected to the lifting member 53 , the lifting member 53 is connected to the pre-pressing driving mechanism 92 , and the heat sealing driving mechanism 52 is connected to the pre-pressing driving mechanism 92 .

[0064] Before heat sealing, pre-pressing is required to facilitate vacuuming. The working process of the utility model is as follows: after pressing the first button and the second button, the pre-pressing drive mechanism starts, driving the lifting member to descend, and the upper and lower pre-pressing blocks are close to each other, and the bag mouth with the vacuum nozzle is pre-pressed to ensure the vacuuming effect. After the vacuuming is completed, the vacuum nozzle is taken out of the bag mouth and put back on the placement platform. After the induction switch on the placement platform senses that the vacuum nozzle has returned to its position, the heat sealing drive mechanism is controlled to drive the pre-pressing drive mechanism to descend and drive the lifting member to descend further, and the heat sealing blocks are closer to each other for heat sealing. After the heat sealing set time, it automatically closes to complete the heat sealing.

[0065] In this embodiment, the pre-compression block and the heat-sealing block are arranged side by side. When the pre-compression driving mechanism drives the lifting member to move, not only the pre-compression blocks are close to each other, but also the heat-sealing blocks are close to each other. After the vacuuming is completed, the heat-sealing driving mechanism is further actuated to further reduce the distance between the heat-sealing blocks, so that the bag opening is heat-sealed.

[0066] In this embodiment, the heat sealing time and the heat sealing temperature can be set in advance through the equipment operation screen to achieve heat sealing of outer packaging bags of different materials.

[0067] In this embodiment, a spring is provided on the pre-pressing block 91 .

[0068] The design of the spring provides a certain buffer space for the pre-compression block, which will not cause damage to the vacuum nozzle; and the bag opening can be compressed when vacuuming.

[0069] The working principle of the utility model is as follows: the material is transported to the material taking position through the conveying mechanism, and the material is manually transferred from the conveying mechanism to the bagging platform for bagging through the gloves outside the isolator, and then put back to the material conveying mechanism, and the bag outside the material is vacuumed. After the vacuuming is completed, the vacuuming mechanism is put back on the placement platform, and the first button and the second button are set at a distance, and one hand cannot press them at the same time. Both hands are required to press the two buttons separately. At the same time, because the first button and the second button are connected in series, pressing one button with one hand cannot activate the pre-pressing heat sealing mechanism; in summary, it can be seen that the pre-pressing heat sealing mechanism will only start to act when both hands press the first button and the second button, thereby avoiding the risk of fingers being clamped by the pre-pressing heat sealing mechanism during the use of the utility model, ensuring the safety of the operator, and preventing safety risks caused by workers' misoperation.

[0070] Embodiment 2:

[0071] like Figure 1-6 A container nesting and bagging production line is shown, comprising a container conveying line 101, a nest box conveying line 102, a container nesting mechanism 105, the heat sealing device 103 and a buffer station 104. The container conveying line 101 and the nest box conveying line 102 are vertically arranged on a horizontal plane. The container nesting mechanism 105 is used to place the containers on the container conveying line 101 into the nest boxes of the nest box conveying line 102. The heat sealing device 103 is used to bag and heat-seal the nest boxes with the containers placed therein. The buffer station 104 is used to cache the nest boxes after bagging and heat-sealing.

[0072] The container is transported to the material taking place of the container nesting mechanism through the container conveyor line, and the empty nest box is transported to the place for receiving the container through the nesting box conveyor line. The container is placed into the empty nest box through the container nesting mechanism to complete the nesting of the container; the nest box with the container enters the manual bagging vacuum heat sealing device to bag and heat seal the nest box, and the heat-sealed nest box enters the nest box buffer station for buffering.

[0073] In this embodiment, the container conveying line and the material conveying mechanism in the manual bagging vacuum heat sealing device are in the same straight line on the horizontal plane, and the buffering station is located on the side of the material conveying mechanism. This layout method makes reasonable use of space and is convenient for operation and later maintenance.

[0074] In this embodiment, the container nesting mechanism is a robot.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
