Description

Technical Field

[0001] This utility model relates to the field of labeling technology, and in particular to an automatic labeling and numbering device for sample tubes. Background Technology

[0002] Sample tubes are a common medical testing supply, typically used in the medical field to hold blood or urine samples. The management of sample tubes usually relies on the labels affixed to them for interpretation and control; therefore, affixing labels to sample tubes is crucial for their management.

[0003] Currently, when patients receive various sample tubes at the hospital, labels are usually manually affixed to the tubes by relevant personnel or nursing staff. This is not only cumbersome and inefficient, but also wastes hospital human resources. Furthermore, manual labeling carries the risk of errors in numbering. Therefore, we propose an automatic labeling and numbering device for sample tubes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic labeling and numbering device for sample tubes.

[0012] An airbag is provided on the bottom surface of the pressure plate.

[0013] As a further improvement of this utility model: an L-shaped plate is fixedly connected to one side of the outer wall of the pressure plate;

[0014] The top surface of the conveying platform near the arc-shaped groove is provided with an insertion port that is compatible with the L-shaped plate.

[0015] As a further embodiment of this utility model: the adhesive label fixing structure includes two fixing heads arranged opposite each other and rotatably connected to the corresponding side of the bracket via a rotating shaft, a sliding groove provided on one end face of the fixing head, two clamps arranged opposite each other and slidably connected to the inner wall of the sliding groove, and a spring fixedly connected to the outer wall of the clamps and the inner circumference of the fixing head.

[0016] As a further embodiment of this utility model: pressure strips are fixedly connected to the outer circumferential walls of the collecting roller A and the collecting roller B, and two limiting plates are sleeved on the outer circumferential walls of the collecting roller A and the collecting roller B, with the pressure strips located between the left and right limiting plates.

[0017] A rubber ring is fixedly connected to the inner circumference of the limiting plate.

[0018] As a further embodiment of this utility model: the intermittent operation component includes a transmission belt rotatably connected to one side of the outer wall of the machine body, a fixed-distance wheel connected to one end of the transmission belt via a connecting shaft, a cross groove provided on one side of the fixed-distance wheel, a T-shaped plate fixedly connected to one side of the outer wall of the machine body, a motor fixedly connected to the top outer wall of the T-shaped plate and electrically connected to the control module, a drive wheel rotatably connected to one side of the T-shaped plate, and an eccentric column fixedly connected to one end face of the drive wheel near the circumferential outer wall. The output end of the motor is connected to one end of the drive wheel via a coupling, and the eccentric column is inserted into the inner wall of the cross groove.

[0019] One end of each of the two rollers on the transmission belt is connected to one end of collecting roller A and collecting roller B respectively via a synchronous shaft.

[0020] As a further improvement of this utility model, a control panel is fixedly connected to one side of the outer wall of the machine body.

[0021] As a further improvement of this utility model, an inclined buffer plate is fixedly connected to one side of the inner wall of the material collection trough.

[0022] Compared with the prior art, this utility model provides an automatic labeling and numbering device for sample tubes, which has the following beneficial effects:

[0023] 1. This automatic labeling and numbering device for sample tubes, equipped with an inclined conveyor platform and a pressure ejection component, allows the sample tubes to be labeled to be placed in the material cylinder after the material gate is opened. The sample tubes are automatically dropped from the outlet onto the conveyor platform in sequence. During the conveying process, the pressure ejection component completes the automatic labeling before the tubes are transported to the collection trough for collection. This device can automatically label sample tubes and automatically replace labels, reducing manual intervention, making it convenient to use and improving work efficiency.

[0024] 2. This sample tube automatic labeling and numbering device starts the motor and drives the drive wheel to rotate. With each rotation of the drive wheel, the eccentric column drives the fixed-distance rotating wheel to rotate 45° through the cross groove. This causes the collecting rollers A and B to rotate intermittently under the fixed-distance transmission of the transmission belt. This allows for the automatic winding of the label backing paper and the excess label edge, so that the next label can be passively transported to the bottom of the pressure plate to provide label support for the next round of labeling.

[0025] 3. This automatic labeling and numbering device for sample tubes uses a distance sensor to detect the distance between the pressure plate and the device in real time. When the distance reaches a set value, a signal is transmitted to the control module, which then activates the electric telescopic rod to move the airbag downwards. This allows the paper-removed adhesive label, located between collecting rollers A and B, to be pressed and transferred onto the outer wall of the sample tube within the arc-shaped groove. At this point, the distance sensor detects that the distance between the pressure plate and the device has reached the remote distance value, and transmits a signal to the control module. This allows the control module to activate the electric telescopic rod to reset the pressure plate. Under the action of the connecting rod, the semi-circular plate moves upwards synchronously, protruding out of the groove and ejecting the labeled sample tube from the arc-shaped groove. Since the surface of the higher conveyor platform on one side of the arc-shaped groove is covered with other unlabeled sample tubes, the ejected labeled sample tubes can slide onto the lower conveyor platform and automatically roll into the collection trough for collection, thus achieving automatic material handling of the labeled sample tubes.

Therefore, they should not be construed as limitations on this utility model.

[0037] Example 1

[0038] An automatic labeling and numbering device for sample tubes, such as Figures 1-8 As shown, the machine includes a body 1. The top surface of the body 1 is provided with an inclined conveying platform 101 so that the sample tubes can be automatically rolled and conveyed under the action of centrifugal force. The top edge of the body 1, which is located at the front and rear ends of the conveying platform 101, is provided with a material cylinder 2 for storing sample tubes and a material collection trough 7 for storing labeled sample tubes. The bottom end of the material cylinder 2 is fixed to the top outer wall of the body 1 by bolts, and the material collection trough 7 is opened on the top surface of the body 1.

[0039] Preferably, the outer circumferential wall of the material cylinder 2 is hinged with a material gate 202, and the outer circumferential wall of the material cylinder 2 near the bottom is provided with a discharge port 201; when the material gate 202 is opened, the sample tube to be labeled is placed in the material cylinder 2 and stored therein. The sample tubes to be labeled are automatically dropped out from the discharge port 201 in sequence onto the conveying platform 101. During the conveying process, the labels are automatically labeled and then conveyed to the collection trough 7 for collection.

[0040] Preferably, an inclined buffer plate 701 is fixed to one side of the inner wall of the collection trough 7 by bolts; it is used to buffer the label sample tubes rolling off the conveying table 101 into the collection trough 7, and to prevent them from being damaged when falling due to height difference.

[0041] Furthermore, the top surface of the machine body 1 is provided with an inverted U-shaped bracket that is integral with it. On the opposite side of the bracket, from front to back, there are a paper label fixing structure, a collection roller A5 for winding the label backing paper with the same structure, and a collection roller B6 for winding the excess label edge. The paper label fixing structure includes two fixing heads 3 that are arranged opposite each other and are rotatably connected to the opposite side of the bracket through a rotating shaft, a slide groove opened on one end face of the fixing head 3, two clamping plates 301 that are slidably connected to the inner wall of the slide groove with opposite positions, and a spring 302 that is welded to the outer wall of the clamping plate 301 and the inner circumference of the fixing head 3.

[0042] During assembly, the adhesive label is rolled onto the outer cylinder, and then both ends of the outer cylinder are inserted into the left and right fixing heads 3 respectively. This allows the clamping plate 301 to firmly hold the outer walls of both ends of the outer cylinder under the action of the spring 302, making assembly and disassembly relatively convenient.

[0043] Preferably, the outer circumferential walls of the collecting roller A5 and / or collecting roller B6 are each fixed with a pressure strip 602 for clamping and fixing the bottom paper or excess face material frame by bolts, and two limiting plates 601 are sleeved on the outer circumferential walls of the collecting roller A5 and / or collecting roller B6, with the pressure strip 602 located between the left and right limiting plates 601.

[0044] Further preferably, a rubber ring is welded to the inner circumference of the limiting plate 601; this improves the firmness and tightness of the connection between the limiting plate 601 and the outer wall of the collecting roller A5 and / or the collecting roller B6.

[0045] Furthermore, the top surface of the conveying platform 101 located between the collecting rollers A5 and B6 is provided with an arc-shaped groove for temporarily placing the sample tubes to be labeled. The bottom surface of the support above the arc-shaped groove is provided with a pressure ejection component for automatically labeling the sample tubes. The pressure ejection component includes a distance sensor 12 and an electric telescopic rod 13 fixed to the bottom surface of the support by bolts, an arc-shaped pressure plate 14 fixed to the extension end of the electric telescopic rod 13 by bolts, a J-shaped connecting rod 10 fixed to one side of the pressure plate 14 by bolts, a semi-circular plate 8 fixed to one end face of the connecting rod 10 by bolts, a through 9 opened on one side inner wall of the machine body 1 and forming a sliding fit with the outer wall of the connecting rod 10, and a groove opened on the inner wall of the arc-shaped groove. The semi-circular plate 8 and the groove form a sliding fit.

[0046] Preferably, the ranging sensor 12 and the electric telescopic rod 13 are electrically connected to the control module;

[0047] Preferably, an air bladder 4 is bonded to the bottom surface of the pressure plate 14; this allows it to press the label codes on the outer surface of sample tubes of different diameters.

[0048] During operation, the distance sensor 12 detects the distance between the pressure plate 14 and the pressure plate 14 in real time. When the distance reaches the set value, it transmits a signal to the control module so that the control module can start the electric telescopic rod 13, which then presses down the airbag 4 to transfer the paper-removed adhesive label code between the collecting rollers A5 and B6 to the outer wall of the sample tube in the arc-shaped groove. At this time, the distance sensor 12 detects that the distance between the pressure plate 14 and the pressure plate 14 has reached the remote distance value, so it transmits a signal to the control module so that the control module can operate the electric telescopic rod 13 to carry the pressure plate 14 back to its original position. Then, under the action of the connecting rod 10, it drives the semi-circular plate 8 to move upward synchronously, so that it protrudes out of the groove and pushes out the sample tube with the label in the arc-shaped groove. Since the surface of the feeding platform 101, which is higher on one side of the arc-shaped groove, is covered with the remaining unlabeled sample tubes, the pushed-out labeled sample tubes can slide onto the lower feeding platform 101 and automatically roll into the collection trough 7 for collection, thereby realizing the automatic material picking operation of the labeled sample tubes.

[0049] To enable the winding of label backing paper and excess label edge material, an intermittent operation assembly is provided on one outer wall of the machine body 1. This assembly includes a transmission belt 16 rotatably connected to the outer wall of the machine body 1, a fixed-distance roller 18 connected to one end of the transmission belt 16 via a connecting shaft, a cross groove 1801 on one side of the fixed-distance roller 18, a T-shaped plate bolted to the outer wall of the machine body 1, a motor 17 bolted to the top outer wall of the T-shaped plate and electrically connected to the control module, a drive wheel 20 rotatably connected to one side of the T-shaped plate, and an eccentric column 2001 bolted to one end of the drive wheel 20 near its circumferential outer wall. The output end of the motor 17 is connected to one end of the drive wheel 20 via a coupling. The eccentric column 2001 is inserted into the inner wall of the cross groove 1801. Figure 7 As shown;

[0050] Furthermore, one end of each of the two rollers on the transmission belt 16 is connected to one end of the collecting roller A5 and the collecting roller B6 respectively via a synchronous shaft;

[0051] In operation, the control motor 17 starts, driving the drive wheel 20 to rotate. For each revolution of the drive wheel 20, the eccentric column 2001 drives the fixed-distance rotating wheel 18 to rotate 45° via the cross groove 1801. This causes the collecting rollers A5 and B6 to rotate intermittently under the fixed-distance transmission of the drive belt 16, thus automatically winding up the label backing paper and excess label edge material. This passively transports the next label to the pressure plate 14 for label support in the next round of labeling. Figure 8 As shown, it is quite convenient to use.

[0052] This structure, in conjunction with the pressure ejection component, enables automatic labeling of sample tubes and automatic replacement of labels to be labeled, reducing manual intervention.

[0053] Furthermore, a control panel 11 is fixed to one side of the outer wall of the body 1 by bolts. The control panel 11 includes a control module, a power supply, etc.

[0054] Working principle: During assembly, the adhesive label roll is placed on the outer cylinder, and then both ends of the outer cylinder are inserted into the left and right fixing heads 3 respectively, so that the clamping plate 301 firmly holds the outer walls of both ends of the outer cylinder under the action of the spring 302. Then, a section of adhesive label is pulled out and peeled off, so that one end of the label backing paper is wrapped around the collecting roller A5, while the excess face material edge of the label without backing paper is wrapped around the collecting roller B6. The material gate 202 is opened and the sample tube to be labeled is placed in the material cylinder 2. The sample tubes to be labeled automatically fall out from the discharge port 201 to the conveying table 101 in sequence. The first sample tube will fall into the arc groove and automatically center itself. The label is automatically labeled during the conveying process and then conveyed to the collection trough 7 for collection.

[0055] Specifically: Before operation, the control panel 11 sets the operating program for the motor 17 and the electric telescopic rod 13 [this is existing technology and will not be described in detail here]; during operation, the distance sensor 12 detects the distance between the pressure plate 14 and the pressure plate 14 in real time. When the progress distance reaches the set value, it transmits a signal to the control module so that it can control the electric telescopic rod 13 to start, thereby pressing down the airbag 4 to move it down, so as to press and transfer the adhesive label code after the bottom paper is removed between the collecting rollers A5 and B6 to the outer wall of the sample tube in the arc groove. At this time, the distance sensor... If the distance between the pressure plate 14 and the pressure plate 14 reaches the remote distance value, a signal is transmitted to the control module so that the electric telescopic rod 13 can be operated to carry the pressure plate 14 back to its original position. Then, under the action of the connecting rod 10, the semi-circular plate 8 is moved upward synchronously, so that it protrudes out of the groove and pushes out the sample tube with the label in the arc groove. Since the surface of the feeding platform 101, which is higher on one side of the arc groove, is covered with the remaining unlabeled sample tubes, the pushed-out labeled sample tubes can slide onto the feeding platform 101, which is lower, and automatically roll down into the collection trough 7 for collection. Furthermore, during the upward repositioning of the electric telescopic rod 13, the control module will start the motor 17, driving the drive wheel 20 to rotate. For each rotation of the drive wheel 20, the eccentric column 2001 will drive the fixed-distance rotating wheel 18 to rotate 45° via the cross groove 1801. This causes the collecting rollers A5 and B6 to rotate intermittently under the fixed-distance transmission of the transmission belt 16, thereby automatically winding up the label backing paper and the excess label edge, so that the next label can be passively transported to the pressure plate 14 to provide label support for the next round of labeling.

[0056] Example 2

[0057] An automatic labeling and numbering device for sample tubes, such as Figures 1-5 As shown, in order to ensure that the unlabeled sample tubes are output in an orderly manner, this embodiment makes the following additions based on embodiment 1: an L-shaped plate 19 is fixed to one side of the outer wall of the pressure plate 14 by bolts; an insertion port 15 adapted to the L-shaped plate 19 is opened on the top surface of the conveying table 101 near the arc groove.

[0058] When the electric telescopic rod 13 moves the pressure plate 14 and the semi-circular plate 8 upward, the semi-circular plate 8 protrudes from the groove, thus lifting the labeled sample tube in the arc-shaped groove and causing it to roll backward out of the arc-shaped groove. At the same time, the semi-circular plate 8 also limits the unlabeled sample tubes on the forward conveyor table 101, preventing the next one from entering the arc-shaped groove. When the electric telescopic rod 13 moves the pressure plate 14 and the semi-circular plate 8 downward, the semi-circular plate 8 gradually hides in the groove. At this time, a gap is left between the L-shaped plate 19 and the conveyor table 101 so that the next unlabeled sample tube can automatically roll into the arc-shaped groove to wait for labeling. During the continuous descent, the L-shaped plate 19 will move slowly downward until it is inserted into the socket 15, thus limiting the remaining unlabeled sample tubes in the forward direction while the labeling operation is being performed. This structure ensures the orderly sequential output of unlabeled sample tubes.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
