Description

Technical Field

[0001] This utility model relates to the field of blood product technology, and in particular to a blood box end-side printing device. Background Technology

[0002] Medical blood is stored in flat blood bags, each marked with a barcode or QR code containing blood information. To prevent breakage during transport, the blood bags are typically repackaged. For automated crating and order-based sorting, rigid boxes are usually used for this secondary packaging. To ensure the information on the blood crate matches the information on the blood bag it contains, the corresponding blood information needs to be printed on the blood crate. This requires a device that facilitates printing this information on the blood crate. Utility Model Content

[0003] To address the problem of printing blood information on blood boxes, this invention proposes a blood box end-side printing device, which facilitates printing corresponding blood information on blood boxes during transport.

[0004] The technical solution adopted in this utility model is to design a blood box end-side printing device, including a conveyor belt for conveying blood boxes and a blood box position detection device for detecting the position of the blood boxes. A printing head and a blocking part corresponding to the end side of the blood box are arranged relative to the conveying direction of the conveyor belt. The printing head and the blocking part are controlled by a moving device to move laterally relative to the conveyor belt, so that the printing head and the blocking part move to or away from the front of the blood box.

[0005] In some embodiments, the blocking portion and the print head are arranged side by side in the direction of movement of the moving device.

[0006] In some embodiments, the print head and the blocking portion are relatively fixed and transverse to the conveyor belt, with the print head located in front of the blocking portion.

[0007] In some embodiments, the blocking part is a stop block, and the stop block is higher than the print head in the direction facing the blood box.

[0008] In some embodiments, a limiting channel is provided above the conveyor belt in front of the print head to restrict the blood box from moving laterally toward the conveyor belt. When the blocking part blocks the end side of the blood box, the blood box is located within the limiting channel.

[0009] In some embodiments, the blood box position detection device is a first position detection sensor disposed on the limiting channel for detecting whether the blood box has entered the limiting channel.

[0010] In some embodiments, the limiting channel includes two limiting plates disposed opposite to each other, and the first position detection sensor is a photoelectric transmitter disposed on the two limiting plates.

[0011] In some embodiments, the limiting channel inlet is a flared guide opening.

[0012] In some embodiments, a second position detection sensor for detecting the position of the blood box is provided behind the print head, corresponding to the conveying direction of the conveyor belt.

[0013] In some embodiments, the conveyor belt includes a first conveyor belt and a second conveyor belt, the first conveyor belt and the second conveyor belt being arranged consecutively in the conveying direction, the second conveyor belt being located below the print head and the blocking part, and the height of the second conveyor belt being lower than that of the first conveyor belt.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes a printhead and a blocking part that can move relative to the conveyor belt to print blood information codes on the end face of a blood box on the conveyor belt. The blocking part is higher than the printhead in the direction facing the blood box, protecting the inkjet nozzle while maintaining a suitable inkjet gap between the nozzle and the end of the blood box, thus ensuring inkjet effect. By setting a limiting channel for the blood box on the conveyor belt, the limiting channel and the blocking part together keep the position of the blood box on the conveyor belt stable, which is beneficial to the stability of printing.

Detailed Implementation

[0022] The following are specific embodiments of this utility model, and the technical solution of this utility model will be further described with reference to the accompanying drawings. However, this utility model is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of features described in the embodiments are not necessarily necessary for the solution of the utility model.

[0023] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] Medical blood is stored in flat blood bags, each marked with a barcode or QR code containing blood information. To prevent breakage during transport, the blood bags undergo secondary packaging. This secondary packaging typically uses rigid boxes to facilitate automated crating and order-based sorting. To ensure the information on the blood crate matches the information on the blood bag it's placed in, the corresponding blood information needs to be printed on the blood crate.

[0026] Therefore, such as Figure 1 , 2 As shown in Figure 3, a blood box 1 end-side printing device is provided, including a conveyor belt 2 for conveying the blood box 1 and a blood box position detection device for detecting the position of the blood box 1. A print head 31 and a blocking part 4 corresponding to the end side of the blood box 1 are arranged relative to the conveying direction of the conveyor belt 2. The print head 31 and the blocking part 4 are controlled by a moving device 5 to move laterally relative to the conveyor belt 2, so that the print head 31 and the blocking part 4 move to or move away from the front of the blood box 1.

[0027] The print head 31 and the blocking part 4 are located in front of the blood box 1. When the blood box position detection device detects that the front end of the blood box on the conveyor belt has moved to the blocking part, it sends a stop command to the conveyor belt, causing the conveyor belt to stop rotating. The blocking part can prevent the blood box from moving forward due to inertia, thus allowing the blood box to stop at a suitable position from the print head. The blocking part 4 can abut against the end of the blood box 1, preventing the blood box 1 from moving forward. Then, the print head 31 can print the corresponding blood information on the end of the blood box 1, so that the blood box 1 information printed on the blood box 1 matches the blood information of the blood bag inside the blood box 1. When the blocking part 4 abuts against the end of the blood box 1, the conveyor belt 2 can be stopped. The end of the blood box 1 has a protrusion 11, on which the blood information is printed, and the blocking part 4 abuts against the protrusion 11.

[0028] The blocking part 4 and the print head 31 are arranged side by side in the moving direction of the moving device 5, so as to control the blocking part 4 and the print head 31 to move synchronously.

[0029] The print head and the blocking part are fixed relative to each other and transverse to the conveyor belt 2. The print head 31 is located in front of the blocking part 4 so that the blocking part 4 contacts the protrusion 11 of the box body first. In this embodiment, the print head 31 is the inkjet printer nozzle of the inkjet printer 3, so as to print the corresponding information code representing blood information, such as a QR code, on the blood box 1. The blocking part 4 is a stop block, which is set on the printer 3. The stop block is higher than the print head 31 in the direction facing the blood box 1, so as to protect the inkjet nozzle and maintain a suitable inkjet distance between the inkjet nozzle and the end of the blood box 1, thereby ensuring the inkjet effect. The printer 3 is controlled to move by the moving device 5, which is, for example, a cylinder, electric cylinder, or other device that can move linearly.

[0030] A limiting channel is provided above the conveyor belt 2 in front of the print head 31 to restrict the blood box 1 from moving laterally toward the conveyor belt 2. When the blocking part 4 blocks the end of the blood box 1, the blood box 1 is located in the limiting channel, preventing the blood box 1 from moving to both sides. Thus, together with the stop block, the position of the blood box 1 on the conveyor belt 2 is kept stable, which is beneficial for printing.

[0031] The blood box position detection device is a first position detection sensor 7 installed on the limiting channel to detect whether the blood box has entered the limiting channel. In this embodiment, the limiting channel includes two limiting plates 6 arranged opposite each other. The first position detection sensor 7 is a photoelectric beam tube installed on the two limiting plates 6. When the blood box 1 is detected to have reached a suitable position, the conveyor belt 2 stops rotating. This suitable position is, for example, the position of the blood box 1 when it touches the stop. After the conveyor belt 2 stops rotating, the moving device 5 moves to the right, causing the stop to move to the right away from the front of the blood box. At this time, the inkjet nozzle of the coding machine 3 starts inkjet printing. The coding machine continues to move to the right, printing a QR code of blood information on the end side of the blood box from left to right, so that the coding nozzle of the coding machine 3 corresponds to the center of the end side of the blood box 1. Then, the two-dimensional blood information code is printed on the end side of the blood box 1 through the coding nozzle. After coding, the moving device 5 moves to the right, so that the coding machine 3 moves away from the front of the blood box 1. Then the conveyor belt 2 rotates, so that the blood box 1 continues to move forward to the next process. After the blood box 1 leaves, the moving device 5 moves to the left, so that the coding machine 3 is in front of the limiting channel, so as to block the next blood box 1 entering the channel, thereby coding the next blood box 1.

[0032] The limiting channel inlet is a trumpet-shaped guide opening to facilitate the entry of the blood box 1.

[0033] Corresponding to the conveying direction of the conveyor belt 2, a second position detection sensor 8 is provided behind the print head 31 to detect whether the blood box 1 has left the position corresponding to the coding machine 3, so as to proceed to the printing of the next blood box. The second position detection sensor 8 is a photoelectric photodiode.

[0034] Example 2

[0035] like Figure 4 As shown, unlike the above embodiment, the conveyor belt includes a first conveyor belt 21 and a second conveyor belt 22. The first conveyor belt and the second conveyor belt are arranged consecutively in the conveying direction. The second conveyor belt is located below the print head and the blocking part. The height of the second conveyor belt is lower than that of the first conveyor belt, so that when the first conveyor belt stops, it does not affect the transmission of the blood box after printing on the second conveyor belt. The lower height of the second conveyor belt also helps to make way for the protrusion below the coding machine.

[0036] Furthermore, the height of the print head and the blocking part from the second conveyor belt can be greater than the height of the blood box. This allows the coding machine to move to the left in front of the limiting channel as soon as the printed blood box falls onto the second conveyor belt, without waiting for the previously coded blood box to completely move out of the position corresponding to the coding machine. This facilitates faster printing of the next blood box conveyed from the first conveyor belt, improving printing efficiency.

[0037] 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.

[0038] Although this document uses a number of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention. The order of actions, steps, etc., in the apparatus and methods shown in the specification and drawings can be implemented in any order unless a specific order is explicitly specified, and as long as the output of a preceding process is not used in a subsequent process. Similar sequential terms used for descriptive convenience (e.g., "firstly," "next," "secondly," "again," "then," etc.) do not imply that the actions must be performed in such an order.

[0039] Those skilled in the art will understand that all directional references (e.g., above, below, up, up, down, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and do not imply (e.g., a limitation on the scope of the invention as defined by the appended claims) a limitation on the scope of the invention as defined by the appended claims. They are merely for the purpose of facilitating the description of this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation. The directional terms "inside" and "outside" refer to inside or outside relative to the outline of the respective components themselves.

[0040] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0041] Additionally, some vague terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or minor deviations in conditions, quantities, values, or dimensions, some of which are within manufacturing tolerances or limits. It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components; unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
