Description

Technical Field

[0001] This utility model relates to the field of blood product technology, and in particular to a blood bag packaging device. Background Technology

[0002] According to my country's blood management regulations, blood collection, preparation, and supply in cities are centralized at blood banks, which then provide qualified blood to hospitals. The blood is packaged in special blood bags. For safety reasons, the blood undergoes secondary packaging before leaving the blood bank, typically using transparent plastic bags. While inexpensive, these bags are inconvenient for robotic arms and hinder automated blood management. One solution is to place the blood bags in transparent plastic bags into rigid plastic boxes, facilitating subsequent robotic operations. The bagged blood is then removed from the box upon leaving the blood bank, and the box is reused within the bank; hence, it's called a turnover box. Red blood cells are a commonly used blood type in hospitals. Compared to other blood types, red blood cells are liquid, and the shape of the blood bags is unstable, making direct pushing into boxes difficult. Therefore, current methods involve manual bagging and boxing, which is inefficient. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a blood bag packaging device that squeezes bagged blood into a turnover box.

[0004] The blood bag boxing equipment and labeling and bagging machine are used together to automate the blood labeling, packaging and boxing process.

[0005] The technical solution adopted in this utility model is to design a blood bag boxing device, including a conveyor belt for transporting blood bags and a turnover box conveying device for transporting turnover boxes. The discharge end of the conveyor belt corresponds to the opening end of the turnover box conveyed by the turnover box conveying device. An auxiliary conveyor belt is arranged above the discharge end of the conveyor belt. The conveyor belt and the auxiliary conveyor belt are arranged side by side to form a blood bag conveying channel corresponding to the opening end of the turnover box. The auxiliary conveyor belt rotates in the opposite direction to the conveyor belt, and the blood bags located therein are squeezed and sent into the open turnover box.

[0006] In some embodiments, the system further includes a lifting device for controlling the height of the auxiliary conveyor belt relative to the transport conveyor belt, and a height detection device located in front of the blood bag conveying channel for detecting the height of the blood bags on the transport conveyor belt. The lifting device controls the height of the auxiliary conveyor belt based on the height of the blood bags, such that the vertical distance between the auxiliary conveyor belt and the transport conveyor belt is slightly less than the height of the blood bags, thereby allowing the blood bags to be held between the auxiliary conveyor belt and the transport conveyor belt and fed into the transfer box. In some embodiments, the system also includes a blood bag position detector for detecting the position of the blood bags on the transport conveyor belt. The auxiliary conveyor belt is an active conveyor belt with a drive device, which controls whether the auxiliary conveyor belt rotates based on the blood bag position information. To prevent damage to the blood in the blood bags due to excessive pressure, the downward movement of the auxiliary conveyor belt is precisely controlled by a pressure control device.

[0007] In some embodiments, the turnover box conveying device includes a turnover box conveyor belt, the discharge end of which corresponds to the side of the turnover box conveyor belt.

[0008] In some embodiments, a baffle is provided on the other side of the turnover box conveyor belt opposite to the transport conveyor belt to block the turnover boxes on the turnover box conveyor belt.

[0009] In some embodiments, the turnover box conveyor belt includes a front conveyor belt, a middle conveyor belt, and a rear conveyor belt arranged consecutively in the conveying direction. The side of the middle conveyor belt corresponds to the discharge end of the conveyor belt. A front stop is provided between the front conveyor belt and the middle conveyor belt, and a rear stop is provided between the middle conveyor belt and the rear conveyor belt. The front stop and the rear stop are driven by their respective motors to block or allow the turnover box to move.

[0010] The blood bag boxing equipment and labeling and bagging machine are used together to realize the blood labeling and packaging production line, thereby automating the blood and boxing operation process.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes an auxiliary conveyor belt located above the main conveyor belt, forming a blood bag conveying channel corresponding to the opening end of the turnover box. The main conveyor belt and the auxiliary conveyor belt operate in opposite directions, jointly squeezing and feeding the blood bags into the turnover box. The auxiliary conveyor belt can move up and down. A photoelectric sensor detects whether there are blood bags on the conveyor belt, the position of the blood bags, and the height of the blood bags, controlling the operation and height of the auxiliary conveyor belt to achieve vertical clamping and conveying of the blood bags. A pressure control device precisely controls the downward movement of the auxiliary conveyor belt to prevent excessive pressure from damaging the blood in the blood bags.

[0013] The blood bag packaging equipment, combined with the labeling and bagging machine, can automate the processes of labeling, bagging, and boxing blood. Its structure can adapt to common blood types, thereby increasing its applicability and improving work efficiency. Attached Figure Description

[0024] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example

[0026] like Figure 1 , 2 As shown, a blood bag packaging device includes a conveyor belt 10 for transporting blood bags and a transfer box 3 conveying device for transporting transfer boxes 3. The discharge end of the conveyor belt 10 corresponds to the port of the transfer box 3 conveyed by the transfer box 3 conveying device. An auxiliary conveyor belt 12 is provided above the discharge end of the conveyor belt 10. The conveyor belt 10 and the auxiliary conveyor belt 12 are arranged side by side to form a blood bag conveying channel corresponding to the port of the transfer box 3. The auxiliary conveyor belt 12 rotates in the opposite direction to the conveyor belt 10. The two rotate simultaneously to send the blood bag sandwiched between them into the blood box in front. The clamping effect of the two can prevent the blood bag from deforming during the conveying, which is conducive to the smooth delivery of the blood bag into the transfer box 3.

[0027] like Figure 7 As shown, the system also includes a lifting device 14 for controlling the height of the auxiliary conveyor belt 12 relative to the transport conveyor belt 10, and a height detection device 16 located in front of the blood bag conveying channel for detecting the height of the bagged blood 13 on the transport conveyor belt 10. The lifting device 14 controls the height of the auxiliary conveyor belt 12 according to the height of the bagged blood 13, so that the vertical distance between the auxiliary conveyor belt 12 and the transport conveyor belt 10 is slightly less than the height of the bagged blood 13, thereby allowing the bagged blood 13 to be held between the auxiliary conveyor belt 12 and the transport conveyor belt 10 and fed into the turnover box 3. The height detection device 16 can be a non-contact distance detection sensor such as optical or ultrasonic sensors, which determines the height of the blood bag by detecting the distance between the sensor and the blood bag. This is conventional technology in the field and will not be described in detail here.

[0028] The lifting device 14 utilizes a telescopic device, such as a cylinder or electric cylinder, to control the lifting and lowering of the auxiliary conveyor belt 12. Simultaneously, a pressure detection device can be installed to detect the pressure exerted by the auxiliary conveyor belt 12 on the blood bag. A pressure sensor 15 is used to detect the pressure of the auxiliary conveyor belt 12 on the blood bag, ensuring the pressure is at a suitable value to prevent deformation of the blood bag without applying excessive force. Alternatively, the pressure detection device can also be used as a height detection device 16; higher pressure indicates a higher blood bag height, allowing the auxiliary conveyor belt 12 to be slightly raised.

[0029] It also includes a blood bag position detector 17 that detects the position of the bagged blood 13 on the conveyor belt 10. The auxiliary conveyor belt 12 is an active conveyor belt with a drive device. The drive device controls whether the auxiliary conveyor belt 12 rotates according to the position information of the bagged blood 13. The auxiliary conveyor belt 12 only starts to rotate when it is detected that the blood bag is about to reach the position of the auxiliary conveyor belt 12, thereby assisting the conveyor belt 10 in sending the blood bag into the blood box.

[0030] The photoelectric sensor 5 can be, for example, a photoelectric tube or other object position sensor that can detect the presence of an object by whether the light is blocked. This is conventional technology in this field and will not be described in detail here.

[0031] That is, the auxiliary conveyor belt 12 is located above the transport conveyor belt 10, and its operating direction is opposite to that of the transport conveyor belt 10. Together with the transport conveyor belt 10 below it, it sends the bagged blood 13 covered with plastic bags into the turnover box 3. The auxiliary conveyor belt 12 can move up and down. A set of photoelectric sensors is also fixed above the transport conveyor belt 10. The photoelectric sensors detect whether there is bagged blood 13 on the conveyor belt, the position of bagged blood 13 and the height of bagged blood 13, and notify the computer of the obtained signal. The computer controls the operation and height of the auxiliary conveyor belt 12.

[0032] The turnover box 3 conveying device includes a turnover box 3 conveyor belt for transporting the turnover box 3 to the discharge end position of the conveyor belt 10, and the discharge end of the conveyor belt 10 corresponds to the side of the turnover box 3 conveyor belt.

[0033] Opposite to the conveyor belt 10, on the other side of the transfer box 3 conveyor belt, a baffle 9 is provided to block the transfer box 3 from moving along the transfer box 3. The baffle 9 prevents the transfer box 3 from moving backward under the push of the bagged blood products.

[0034] The conveyor belt for the turnover box 3 is a flat conveyor belt 4. The conveyor belt for the turnover box 3 includes a front conveyor belt 41, a middle conveyor belt 42, and a rear conveyor belt 43 that are arranged consecutively in the conveying direction. The side of the middle conveyor belt 42 corresponds to the discharge end of the conveyor belt 10. A front stopper 6 is provided between the front conveyor belt 41 and the middle conveyor belt 42, and a rear stopper 7 is provided between the middle conveyor belt 42 and the rear conveyor belt 43. For example, both the front stopper 6 and the rear stopper 7 include a baffle that can be raised and lowered relative to the conveyor belt for the turnover box 3. The raising and lowering of the baffle can block the turnover box 3, so that the turnover box 3 is conveyed one by one from the front conveyor belt 41 to the middle conveyor belt 42, and then one by one from the middle conveyor belt 42 to the rear conveyor belt 43. When the turnover box 3 is located on the middle section conveyor belt 42, the port of the turnover box 3 corresponds to the end of the bagging conveyor belt 8, thereby sending the bagged blood products into the turnover box 3 on the middle section conveyor belt 42.

[0035] like Figure 3 , 4 As shown, it also includes a turnover box 3 feeding device for feeding the turnover box 3 onto the conveyor belt. The turnover box 3 feeding device includes a vertical hopper 1 for storing the turnover boxes 3 and a feeding conveyor belt located below the hopper 1. The feeding conveyor belt corresponds to the side of the turnover box 3 conveyor belt. The feeding conveyor belt is a partition conveyor belt 2. The hopper 1 has a vertical material cylinder 11. The turnover boxes 3 are stacked vertically in the material cylinder 11. The lower end of the material cylinder 11 corresponds to the partition conveyor belt 2.

[0036] The partition conveyor belt 2 consists of partitions arranged at equal intervals along its length, with vertical partitions opposite the belt surface. Adjacent partitions form feeding compartments. When the lower end of the material cylinder 11 aligns with a feeding compartment, one of the turnover boxes 3 from the material cylinder 11 falls into the corresponding feeding compartment below it. The partition conveyor belt 2 uses a synchronous belt structure with partitions evenly distributed on it. The spacing between the partitions is the same as the spacing between the vertical material cylinders 11 above them, allowing the turnover boxes 3 to automatically fall into the feeding compartments between the partitions. The height of the partitions is no greater than the height of the turnover box 3. Once a turnover box 3 falls between the partitions, the turnover boxes 3 above it cannot fall until the turnover box 3 in the compartment is carried away. Only then can the turnover box 3 above it fall into the next compartment. This ensures that the turnover boxes 3 in the material cylinder 11 fall into the feeding compartments on the conveyor belt one by one.

[0037] like Figure 5 , 6 As shown, the side wall of the material cylinder 11 is provided with a through-hole material feeding notch 111 so that the turnover box 3 can be manually placed into it through the material feeding notch 111.

[0038] The feeding conveyor belts are multiple parallel ones, and multiple material cylinders 11 are arranged in parallel above each feeding conveyor belt along the conveying direction; thus, all the material cylinders 11 form a matrix arrangement structure, which is compact.

[0039] Corresponding to each of the feeding conveyor belts, a detection sensor is provided on the other side of the turnover box 3 conveyor belt to detect whether a turnover box 3 has been conveyed onto the turnover box 3 conveyor belt. The feeding conveyor belt control device controls the rotation of the feeding conveyor belt based on the detection information of the turnover box 3 detection sensor. The photoelectric sensor 5 can be, for example, a photoelectric tube or other object position sensor that can detect the presence of an object by whether light is blocked. This is conventional technology in the art and will not be described in detail here.

[0040] In other words, the storage bin 1 of the turnover box 3 in this embodiment is composed of several vertical cylinders 11 arranged together. The turnover boxes 3 are stacked in the vertical cylinders 11 and fall by their own weight. The partition conveyor belt 2 is arranged at the bottom of the cylinders 11 and carries the turnover boxes 3 in the storage cylinders 11 one by one. The turnover box 3 conveyor belt is a flat conveyor belt 4 perpendicular to the partition conveyor belt 2 and is connected to the partition conveyor belt 2 to receive and send the turnover boxes 3 on the partition conveyor belt 2. The turnover box 3 detection sensor is a photoelectric sensor 5, which detects the status of the turnover boxes 3 on the conveyor belt and transmits the obtained signal to the control device, such as a computer, so as to control the start and stop of the partition conveyor belt 2 according to the signal. If no turnover box 3 is detected at the corresponding position, the partition conveyor belt 2 can be rotated so that the turnover box 3 on the partition conveyor belt 2 falls to that position on the flat conveyor belt 4.

[0041] When the turnover boxes 3 are being loaded, they are manually stacked in the vertical material cylinder 11 of the material cylinder 11. The bottom turnover boxes 3 fall into the feeding compartment on the partition conveyor belt 2 by their own weight. The partition conveyor belt 2 rotates, sending the turnover boxes 3 in the feeding compartment to the flat conveyor belt 4 connected to it. A photoelectric sensor is arranged on one side of the flat conveyor belt 4 to detect the status of the turnover boxes 3 on the flat conveyor belt 4 and transmit the obtained signal to the computer to control the start and stop of the partition conveyor belt 2. At any one time, only one partition conveyor belt 2 is running until the turnover boxes 3 in the vertical material cylinder 11 above the partition conveyor belt 2 are emptied.

[0042] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
