Description

Technical Field

[0001] The invention relates to the technical field of test tube labeling, and in particular to a floor-standing test tube labeling machine. Background Art

[0002] A test tube labeling machine is a machine for sticking labels on the surface of the test tube. The working process of the existing test tube labeling machine is generally as follows: the test tubes to be labeled are loaded into the test tube labeling machine in batches, the test tube labeling machine identifies the positions of the test tubes to be labeled, then prepares sticky labels, and then sticks the sticky labels on the body of each test tube to be labeled in turn.

[0003] Existing test tube labeling machines generally have the following problems: (1) The requirements for the placement of the test tubes are relatively strict, and the user is required to neatly stack each test tube to be labeled in the labeling machine, which results in a huge workload and extremely low efficiency; (2) Due to the relatively strict requirements for the placement of the test tubes, the test tubes to be labeled will not be moved during the labeling process, and a labeling mechanism will be used to label each test tube to be labeled in turn. Since the labeling mechanism itself has a certain volume, there are certain requirements for the placement spacing between the test tubes to be labeled to avoid the situation where adjacent test tubes hinder the movement of the labeling mechanism, thereby significantly reducing the amount of test tubes to be labeled per unit volume; (3) After labeling is completed, the labeled test tubes cannot be discharged by themselves and still need to be taken out manually, which results in a large workload and low efficiency.

The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0035] Please refer to Figures 1 to 9 The embodiment of the present invention provides a floor-standing test tube labeling machine, comprising: a loading rack 10, wherein a plurality of loading slides 12 are provided on the top of the loading rack 10, wherein the lower ends of the plurality of loading slides 12 are located in the same horizontal straight line, wherein the width of the loading slide 12 is slightly larger than the outer diameter of the tube body of the test tube to be labeled, and smaller than the outer diameter of the tube cap of the test tube to be labeled, wherein a pair of elastic clips 15 are vertically provided at the lower end of the loading slide 12, wherein when the elastic clips 15 are in a natural state, the spacing between the elastic clips 15 is smaller than the outer diameter of the tube cap of the test tube to be labeled; and a second tube taking mechanism, wherein the tube taking mechanism is provided with a translation pair, a lifting pair, a tube taking paddle 21 and a tube taking mechanism, wherein the translation pair moves along all the loading slides 12 The line connecting the low ends of the loading slides 12 is translated, the lifting pair is arranged on the translation pair, the tube taking paddle 21 is arranged on the lifting pair, and is located directly above the line connecting the low ends of all the loading slides 12, and the taking over mechanism is located directly below the tube taking paddle 21, and the tube taking paddle 21 is used to press down the test tube to be labeled between any pair of the elastic clips 15 so that the test tube to be labeled falls into the taking over mechanism; the third includes multiple labeling mechanisms, and the entrances of all the labeling mechanisms are respectively connected to the taking over mechanism, and the labeling mechanism is used to label the test tube to be labeled; the fourth includes a tube transferring mechanism and a tube discharging mechanism, and the tube transferring mechanism and the tube discharging mechanism are used to discharge the labeled test tubes.

[0036] The floor-standing test tube labeling machine provided in this embodiment is provided with a loading frame 10, and a plurality of loading slideways 12 are opened on the top thereof, and the width of the loading slideway 12 is limited, so that the test tube to be labeled can be vertically inserted into the loading slideway 12, and the bottom surface of the tube cap is placed on the top surface of the loading slideway 12, so that the test tube to be labeled can slide from the high end to the low end along the loading slideway 12 in sequence, and gradually be stacked in each loading slideway 12 in an orderly manner, thereby realizing efficient regularization and stacking of the test tube to be labeled; on this basis, by A pair of elastic clips 15 are provided at the lower end of the loading slide 12, and the spacing between the pair of elastic clips 15 is limited, so that the test tube to be labeled at the lowest point is clamped between the corresponding pair of elastic clips 15, and a tube taking mechanism is provided, which includes a translation pair, a lifting pair, a tube taking paddle 21 and a pipe taking mechanism. The translation pair is used to translate to drive the tube taking paddle 21 to move to the top of the test tube to be labeled that needs to be taken out, and the lifting pair is used to drive the tube taking paddle 21 to press down the corresponding test tube to be labeled, so that the test tube to be labeled moves down and passes through The elastic clips 15 are squeezed outward through the tube cap and stretched open until the test tube to be labeled falls into the receiving mechanism, and one of the test tubes to be labeled neatly stacked on the loading rack 10 can be accurately taken out. After being taken out, the next test tube to be labeled is clamped between the corresponding elastic clips 15 under the action of gravity and pressure of the other test tubes to be labeled. The above operation is repeated to take out all the test tubes to be labeled on the loading rack 10 in turn; by setting the labeling mechanism, its entrance is connected with the receiving mechanism, so that the test tubes on the loading rack 10 can be taken out in turn by using the receiving mechanism. The test tubes are moved to the labeling mechanism for labeling without moving the labeling mechanism, so there is no need to deliberately expand the spacing between the test tubes to be labeled when they are stacked, which effectively increases the number of test tubes to be labeled in the labeling machine; on this basis, the labeled test tubes are discharged from the labeling machine by setting a tube transfer mechanism and a tube discharge mechanism; through the mutual cooperation of the above-mentioned features, the floor-standing test tube labeling machine can effectively solve the problems of existing test tube labeling machines having relatively strict requirements on the placement of test tubes, a large workload for regular stacking, and extremely low efficiency.

[0037] In order to further explain the specific structure of the loading rack 10 and the loading slide 12, a loading surface 11 is provided on the top of the loading rack 10, and the loading surface 11 is an inclined plane to form a loading side at the highest side of the loading surface 11 and a loading side at the lowest side of the loading surface 11; all the loading slides 12 are opened on the loading surface 11, and the two ends of the loading slide 12 are respectively located at the loading side and the loading side.

[0038] To further explain the specific structure of the loading rack 10, the loading rack 10 includes a loading plate 101, a low-position support plate 102 and a high-position support plate 103; the loading plate 101 is tilted, the upper surface of the loading plate 101 is the loading surface, the loading slide 12 is opened on the loading plate 101, and the loading slide 12 penetrates the loading plate 101 along the thickness direction of the loading plate 101; one side of the low-position support plate 102 is connected to the lowest side of the loading plate 101, and the other side opposite to it is used to contact the ground; one side of the high-position support plate 103 is connected to the highest side of the loading plate 101, and the other side opposite to it is used to contact the ground.

[0039] Through the above arrangement, the loading rack 10 is as lightweight as possible while ensuring structural performance and supporting performance, and does not block the tube body of the test tube to be labeled, so that the status of each test tube to be labeled can be clearly observed from the side.

[0040] Preferably, the loading plate 101 , the low-position supporting plate 102 and the high-position supporting plate 103 are integrally formed.

[0041] In order to further improve the structural stability, the high-position support plate 103 is vertically arranged; the low-position support plate 102 is inclined toward the direction of the high-position support plate 103 and is arranged at an acute angle to the loading plate 101; the middle parts of the low-position support plate 102 and the high-position support plate 103 are hollowed out.

[0042] In order to load test tubes to be labeled with different diameters, the widths of all the loading slides 12 are different; the loading slides 12 are straight slides, and all the loading slides 12 are arranged in parallel and equidistantly.

[0043] In order to prevent unnecessary left and right shaking of the test tube to be labeled when it slides down, the loading slide 12 extends in a vertical plane; a guide sliding plate 14 is respectively provided on both sides of the width direction of the loading plate 101, and the guide sliding plate 14 is arranged parallel to the transfer slide 12; a gap is reserved between the guide sliding plate 14 and the loading plate 101, and the width of the gap is less than the tube length of the test tube to be labeled.

[0044] In order to further explain the specific structure of the low end of the loading slide 12, the low end of the loading slide 12 is through-set to form a tube taking port, the width of which is larger than the diameter of the tube cover of the test tube to be labeled, and the elastic clip 15 is arranged in the tube taking port; the top side of the elastic clip 15 is inclined, and when the test tube to be labeled is pressed down, the tube cover of the test tube to be labeled can press into and open the elastic clip 15; the loading side of the loading rack 10 is provided with a baffle 13, and when the test tube to be labeled is located in the tube taking port, the test tube to be labeled contacts and squeezes the baffle 13.

[0045] It should be noted that, during the process of the test tube being pressed down by the tube-taking paddle 21 and falling freely, the baffle 13 can ensure that the inclination angle of the test tube is as small as possible when it falls, so that it can successfully fall into the receiving mechanism.

[0046] In order to further explain the specific structure of the baffle 13, the baffle 13 includes a front baffle 131 and a pair of side baffles 132; the front baffle 131 is arranged at the lowest side of the loading plate 101, the front baffle 131 is vertically arranged, and the setting height of the top side of the front baffle 131 is higher than the setting height of the lowest side of the loading plate 101; the two side baffles 132 are respectively arranged at the two ends of the length direction of the front baffle 131, and are vertically arranged and parallel to the loading slide 12.

[0048] It should be noted that the tube removal mechanism includes a base frame 20 , and the translation pair is arranged on the base frame 20 .

[0049] It should be noted that the above-mentioned lifting and translational pairs all adopt any relevant mechanism in the prior art, for example, a slide rail and slider structure can be used in conjunction with a motor and a track for driving, or a motor and a gear set for driving, or for example, a cylinder or oil cylinder can be used for pushing and pulling, as long as lifting or translation can be achieved.

[0050] In order to make the tube picking piece 21 have a certain elasticity and a large contact area while being sufficiently lightweight, the tube picking piece 21 includes a longitudinal piece 211 and a transverse piece 212. The top of the longitudinal piece 211 is connected to the lifting pair, and the bottom is connected to the transverse piece 212, so that the tube picking piece 21 is L-shaped, and the bottom surface of the transverse piece 212 is used to contact and press down the test tube to be labeled.

[0051] Through the above arrangement, even if the test tube to be labeled itself has a certain degree of skewness, it can be effectively pressed down and adjusted by the tube removal pick.

[0052] In order to further optimize the structure of the tube removal pick 21 and optimize its stress condition, the longitudinal piece 211 includes a vertical portion 2111 and an inclined portion 2112; the top of the vertical portion 2111 is connected to the lifting pair; the top of the inclined portion 2112 is connected to the bottom of the vertical portion 2111, and the bottom is connected to the transverse piece 212; the inclined portion 2112 is arranged at an obtuse angle to the vertical portion 2111 so that the middle part of the transverse piece 212 is located directly below the vertical portion 2111.

[0053] In order to improve the overall structural performance of the tube removal paddle 21 , the vertical portion 2111 , the inclined portion 2112 and the horizontal piece 212 are integrally formed.

[0054] In order to indicate and calibrate the displacement distance of the translation pair, the frame 20 is provided with a channel code tooth plate 22, and the channel code tooth plate 22 extends along the moving direction of the translation pair. The channel code tooth plate 22 is evenly spaced along the length direction and has a plurality of code teeth, and the code teeth are used to indicate and calibrate the displacement distance of the translation pair.

[0055] In order to further explain the specific structure of the take-over mechanism, the take-over mechanism includes a tube transfer bucket 23 and a positioning cross plate 30; the tube transfer bucket 23 is vertically arranged on the translation pair, the bucket mouth of the tube transfer bucket 23 is vertically facing upward, the lowest point of the tube pick 21 is located above the bucket mouth of the tube transfer bucket 23, and is arranged close to the loading rack 10, and the outlet diameter of the tube transfer bucket 23 is slightly larger than the diameter of the test tube to be labeled; the positioning cross plate 30 is horizontally arranged below the tube transfer bucket 23 and extends along the moving direction of the translation pair, and the positioning cross plate 30 is arranged below the tube transfer bucket 23 and extends along the moving direction of the translation pair.

[0056] Through the above-mentioned arrangement, the shape of the tube transfer bucket 23 is utilized to effectively collect and receive the falling test tubes to be labeled, and then lifted by the positioning horizontal plate 30 and moved along with the tube transfer bucket 23. When the tube transfer bucket 23 moves to align with any one of the positioning drop holes 31, the test tubes to be labeled will fall into the positioning drop holes 31 and into the test tube slots 32 of the corresponding labeling mechanism.

[0059] Preferably, the translation pair is provided with a monitoring optical coupler 24, and the monitoring optical coupler 24 is used to monitor the amount of the test tubes to be labeled loaded on the loading rack.

[0061] Through the above arrangement, there is a certain height difference between the positioning horizontal plate 30 and the base plate 33, so as to radially limit the test tube to be labeled at two locations with different heights, thereby effectively ensuring its vertical arrangement.

[0062] In order to effectively support the entire device, all the base plates 33 are located in the same plane; a plurality of supporting legs 35 are vertically provided at the bottom of the base plate 33, and all the supporting legs 35 have the same length.
