Description

Technical Field

[0001] This utility model relates to the technical field of blood collection tube production equipment, specifically to a discharge component and a round automatic labeling machine. Background Technology

[0002] A horizontally fixed labeling device for blood collection tubes is available. A certain number of blood collection tubes are placed into a placement mechanism. The entire device is controlled by an operating table. The placement mechanism sequentially places the blood collection tubes into a moving mechanism, and a subsequent support mechanism moves the label tape and causes the labels to lift. Finally, a labeling mechanism affixes the labels to the blood collection tubes. The placement mechanism includes a trapezoidal frame and a limiting plate. Blood collection tubes are poured into the gap between the limiting plate and the trapezoidal frame. As the blood collection tubes descend along the gap, they come into contact with cleaning cotton, absorbing moisture from the tubes. Because the gap is small, great care must be taken when pouring the blood collection tubes in, otherwise they may easily fall out. Furthermore, blood collection tubes can accumulate at the bottom of the trapezoidal frame, potentially causing blockage or jamming at the outlet. Utility Model Content

[0003] The primary objective of this invention is to provide a discharge assembly that facilitates the feeding of blood collection tubes and prevents jamming.

[0004] The second objective of this invention is to provide an automatic labeling machine for round surfaces that includes the above-mentioned discharge components.

[0005] To achieve the aforementioned first objective, this utility model provides a discharge assembly, including a fixed frame, a feeding roller, a movable plate, a feeding cam, and a feeding wheel. The fixed frame has an inlet at its upper part and an outlet at its bottom. The feeding roller is rotatably mounted at the outlet. The movable plate is inclined downwards at the lower part of the fixed frame and has a hinged end and a free end, the free end extending towards the feeding roller. The feeding cam is rotatably mounted on one side of the movable plate, forcing the free end to swing up and down around the hinged end. The feeding wheel is rotatably mounted on the side of the feeding roller facing away from the movable plate, rotating in the opposite direction to the feeding roller. A pre-defined material passage gap is provided between the feeding wheel and the feeding roller.

[0006] As can be seen from the above scheme, the forward rotation of the feeding roller is used to push out products one by one, while the reverse rotation of the unloading roller is used to push the excess products piled up above the feeding roller backward. On the one hand, this ensures that only one product can pass through the material passage gap at the same time, and on the other hand, it effectively prevents multiple products from stopping at the same time or even getting stuck. By setting the feeding cam, the free end of the movable plate is forced to swing up and down around the hinge end, which is beneficial for guiding the products in the fixed frame and facilitating the movement of products on the movable plate towards the feeding roller, thus preventing products from stopping in the fixed frame.

[0007] A further option is to have several feeding grooves on the peripheral wall of the feeding roller and several unloading grooves on the peripheral wall of the unloading wheel, both of which can be connected to the material passage gap.

[0008] A further design involves providing several protrusions on the peripheral wall of the feeding cam, with the protrusions abutting against the movable plate.

[0009] A further option is to provide a material feeding seat at the bottom of the fixed frame. The material feeding seat has a material feeding channel. The inlet end of the material feeding channel is connected to the material passage gap, and the outlet end of the material feeding channel is arranged downwards.

[0010] A further option is to have at least one sidewall of the fixed frame tilt downwards and extend into the fixed frame.

[0011] To achieve the second objective mentioned above, this utility model provides an automatic round labeling machine, including a conveying component, a labeling component, a label pressing component, a detection component, a rejection component, and the aforementioned discharge component. The labeling component and the label pressing component are arranged above the conveying component along the conveying direction, the discharge component is located at the feeding end of the conveying component, the detection component is located at the front end and / or rear end of the label pressing component, and the rejection component is located at the rear end of the label pressing component and the detection component.

[0012] As can be seen from the above scheme, the detection component is used to detect the printing quality and label pasting quality of the labels in order to pick out defective products; the rejection component is used to reject defective labeled products, which helps to ensure the quality of products in the same batch.

[0013] A further option is to include a rejection component that includes a jet nozzle that blows air onto the conveying surface of the conveying component, or a jet nozzle that blows air from one side of the conveying surface of the conveying component to the other side, to blow away defective products on the conveying surface.

[0014] As can be seen from the above scheme, using air blowing to remove defective labeled products has the advantages of simple structure, convenient operation and no need to contact the product.

[0015] A further option is that the round automatic labeling machine also includes a printing component, which is set on the labeling component.

[0016] A further option is that the detection component includes a first detection component and a second detection component. The first detection component is disposed between the printing component and the label pressing component, and the second detection component is disposed between the label pressing component and the rejection component.

[0017] As can be seen from the above scheme, the first detection component is used to detect defective printed products and prevent them from being labeled; the second detection component is used to detect defective labeled products, making it easier for the rejection component to remove the defective labeled products.

[0018] A further embodiment is that the round automatic labeling machine also includes a guiding component, which is set on the conveying surface of the conveying component and between the discharge component and the labeling component; the guiding component includes a fixed guide bar and a movable guide bar, which are arranged opposite to each other along the width direction of the conveying component, and the distance between the movable guide bar and the fixed guide bar is adjustable.

[0019] As can be seen from the above solution, the guide component can guide the product to land on the conveying surface of the conveying component, which helps to ensure the accuracy of the subsequent labeling position; by setting the distance between the movable guide strip and the fixed guide strip to be adjustable, it is beneficial to be compatible with products of different lengths.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0028] Example of a discharge assembly: See Figures 1 to 3 The discharge assembly 10 provided in this embodiment includes a fixed frame 1, a feeding roller 2, a movable plate 3, a feeding cam 4, a feeding wheel 5, and a discharge seat 6.

[0029] The upper part of the fixed frame 1 is provided with a feeding port 11, the width of which can be equal to the upper width of the fixed frame 1, so that the staff can easily and quickly put the products 20 in batches. The thickness of the fixed frame 1 is slightly greater than the length of the product 20. The bottom of the fixed frame 1 is provided with a discharge port, and the feeding roller 2 is rotatably set at the discharge port for pushing out the products 20 one by one.

[0030] The movable plate 3 is inclined downward and is set in the lower part of the inner side of the fixed frame 1. The upper part of the movable plate 3 is provided with a hinge end 31, which is hinged to the inner wall of the fixed frame 1. The lower part of the movable plate 3 is provided with a free end 32, which extends to one side of the feeding roller 2.

[0031] The feeding cam 4 is rotatably disposed on the lower side of the movable plate 3. Preferably, the feeding cam 4 is disposed near the free end 32. When the feeding cam 4 rotates around its own axis, it can force the free end 32 to swing up and down around the hinge end 31, so that the product 20 located on the movable plate 3 can move smoothly toward the feeding roller 2.

[0032] The feed roller 5 is rotatably mounted on the side of the feed roller 2 facing away from the movable plate 3. Specifically, the feed cam 4 and the feed roller 5 are respectively mounted on the left and right sides of the feed roller 2, and the feed roller 5 is positioned higher than the feed roller 2. A preset width feed gap 7 is provided between the feed roller 5 and the feed roller 2. This preset width is greater than the diameter of one product 20 and less than the sum of the diameters of two products 20, ensuring that only one product 20 passes through the feed gap 7 at any given time. The feed roller 5 rotates in the opposite direction to the feed roller 2. The feed roller 2 pushes the product 20 towards the feed gap 7, and the feed roller 5 pushes excess products 20 away from the feed gap 7 in the opposite direction, which helps to avoid jamming and ensures smooth discharge.

[0033] The peripheral wall of the feeding roller 2 is provided with a plurality of feeding grooves 21. In this embodiment, it is preferred to have a plurality of feeding grooves 21, which are arranged evenly at intervals along the circumference. Adjacent feeding grooves 21 are as close as possible to form a tip 22, which facilitates the setting of a larger number of feeding grooves 21 and increases the frequency and speed of pushing the product 20.

[0034] The circumferential wall of the feeding roller 5 is provided with a plurality of feeding grooves 51. In this embodiment, it is preferred that there are multiple feeding grooves 51, which are evenly arranged at intervals along the circumference. The spacing between two adjacent feeding grooves 51 is relatively large to form a protrusion 52. The width of the protrusion 52 is greater than the width of the tip 22, which is more conducive to pushing excess product 20 in the reverse direction and avoiding jamming. Both the feeding groove 21 and the feeding grooves 51 can communicate with the material passage gap 7.

[0035] The peripheral wall of the feeding cam 4 is provided with a plurality of protrusions 41. In this embodiment, it is preferred that there are multiple protrusions 41, which are evenly arranged at intervals along the circumference and abut against the movable plate 3. During the rotation of the feeding cam 4, the multiple protrusions 41 abut against the bottom wall of the movable plate 3 in sequence, so as to push the free end 32 of the movable plate 3 to float up and down.

[0036] The feeding seat 6 is fixedly mounted on one side of the feeding roller 2 and positioned below the unloading roller 5. A feeding channel 61 is provided in the middle of the feeding seat 6. The inlet end of the feeding channel 61 communicates with the material passage gap 7, and the outlet end of the feeding channel 61 faces downwards. The width of the feeding channel 61 is slightly larger than the diameter of the product 20 to facilitate the sequential passage of the product 20. Preferably, the inlet end of the feeding channel 61 transitions to its middle section in an arc shape, and both the middle section and the outlet end of the feeding channel 61 extend vertically, ensuring that the product 20 within it detaches from the feeding channel 61 under gravity.

[0037] The discharge assembly 10 is also provided with a mounting base 8, a first driving device 9, and a second driving device (not shown in the figure). The mounting base 8 is provided with an inclined sidewall 81, and the fixing frame 1 is disposed on the mounting base 8 and is arranged parallel to the inclined sidewall 81, such that at least one sidewall of the fixing frame 1 extends inclined downward into the fixing frame 1. In this embodiment, preferably, the first sidewall 12 of the fixing frame 1 extends inclined downward into the fixing frame 1, and the second sidewall 13 of the fixing frame 1 can be arranged vertically, with the second sidewall 13 arranged opposite to the first sidewall 12, and the first sidewall 12 and the second sidewall 13 are respectively disposed on both sides of the movable plate 3. The second sidewall 13 can be made of transparent material, which makes it convenient for the staff to observe with the naked eye whether there is a product 20 in the fixing frame 1, and to conveniently put the product 20 into the fixing frame 1 in a timely manner.

[0038] The first drive unit 9 is mounted on the mounting base 8. The drive shaft of the first drive unit 9 is connected to the feeding roller to drive the feeding roller to rotate around its own axis. The second drive unit simultaneously drives the feeding cam 4 and the unloading wheel 5 to rotate via a belt drive mechanism or a chain drive mechanism. Alternatively, there can be two second drive units, each driving the feeding cam 4 and the unloading wheel 5 to rotate respectively. Both the first drive unit 9 and the second drive unit are preferably motors.

[0039] Example of a round automatic labeling machine: See Figures 4 to 7 The automatic labeling machine for round surfaces provided in this embodiment includes a display control module 30, a base 40, a conveying component 50, a discharging component 10, a guiding component 60, a labeling component 70, a printing component 80, a label pressing component 90, a detection component, a rejection component 120, and a material frame 130.

[0040] The base 40 has a cavity for storing maintenance tools and spare parts, and one side of the cavity has an openable door. The bottom of the base 40 is equipped with a soft pad or casters; the soft pad is for vibration damping, and the casters facilitate movement of the base 40. In actual production, the appropriate option can be selected as needed. The display control module 30 is fixedly mounted on the base 40 and includes a touchscreen and buttons for easy operation. The display control module 30 is electrically connected to the conveying assembly 50, the discharging assembly 10, the labeling assembly 70, the printing assembly 80, the label pressing assembly 90, the detection assembly, and the rejection assembly 120.

[0041] The conveying assembly 50 is mounted on the base 40, and a pad is provided between the conveying assembly 50 and the base 40. In the conveying direction of the conveying assembly 50, the discharge assembly 10, the guiding assembly 60, the labeling assembly 70, the printing assembly 80, the label pressing assembly 90, and the rejection assembly 120 are sequentially arranged above the conveying assembly 50.

[0042] The conveying assembly 50 includes a fixed base 501, a protective cover 502, a conveying drive device, two conveyor belts 503, two rollers 504, and multiple rollers 505. The fixed base 501 is L-shaped, with a first opening facing upwards and a second opening facing one side. The protective cover 502 is detachably mounted on the fixed base 501 and seals the second opening. The two rollers 504 are respectively located at both ends inside the fixed base 501. The conveyor belts 503 are wound between the two rollers 504, and the two conveyor belts 503 are arranged opposite each other along the axial direction of the rollers 504. The rollers 505 are located between the two conveyor belts 503 and can rotate around their own axis. The multiple rollers 505 are evenly spaced along the extension direction of the conveyor belts 503. A positioning groove 506 is formed between two adjacent rollers 505. The product 20 is placed in the positioning groove 506 and is conveyed and moved along with the conveyor belts 503.

[0043] The discharge component 10 is installed at the feeding end of the conveying component 50 and is used to transfer batches of products 20 one by one onto the positioning groove 506 of the conveying component 50.

[0044] A guiding component 60 is disposed on the conveying surface of the conveying component 50 and between the discharging component 10 and the labeling component 70. It is used to guide the product 20 located on the conveying surface to ensure the accuracy of subsequent labeling. The guiding component 60 includes a fixed guide bar 601, a movable guide bar 602, and two mounting brackets 603. The two mounting brackets 603 are arranged along the conveying direction and span across both sides of the conveying surface. The fixed guide bar 601 and the movable guide bar 602 are arranged opposite each other along the width direction of the conveying component 50, forming a funnel-shaped guiding space through which the product 20 passes under the conveying action of the conveying component 50. Specifically, the fixed guide bar 601 is fixedly disposed on one side of the conveying surface, and one end of the product 20 abuts against the fixed guide bar 601 to ensure the accurate positioning of the product 20 in the width direction of the conveying surface. The movable guide bar 602 is suspended on two mounting brackets 603 and its position can be adjusted along the width direction of the conveying assembly 50. That is, the distance between the movable guide bar 602 and the fixed guide bar 601 is adjustable to accommodate products 20 of different lengths, improving the practicality of the guiding assembly 60. The mounting brackets 603 have elongated holes. The movable guide bar 602 is detachably connected to the mounting brackets 603 via fasteners 604. The fasteners 604 pass through the elongated holes and connect to the movable guide bar 602, and can move along the length of the elongated holes. The fasteners 604 are screws and nuts.

[0045] The labeling assembly 70 includes a first up-and-down adjustment assembly 701, a first left-and-right adjustment assembly 702, a first adjustment seat 703, a feed reel 704, a take-up reel 705, a peeling plate 706, a rotary drive device 707, and multiple winding posts 708. The first up-and-down adjustment assembly 701 and the first left-and-right adjustment assembly 702 respectively drive the first adjustment seat 703 to move up and down and left and right. The feed reel 704, the take-up reel 705, the peeling plate 706, and the multiple winding posts 708 are all arranged on the same side of the first adjustment seat 703, with the peeling plate 706 inclined downwards towards the conveying surface. The label tape is arranged on the feed reel 704, and the base film of the label tape is arranged on the take-up reel 705. The rotary drive device 707 drives the take-up reel 705 to rotate around its own axis to move the label tape. The middle part of the label tape is wound around each winding post 708 and the peeling plate 706 in a preset order. The setting of multiple winding posts 708 can, on the one hand, flatten the blank labels wound on them to prevent the labels from curling up and affecting printing and labeling, and on the other hand, it can also play a tensioning role to prevent the label tape from collapsing, so as to facilitate printing and pasting.

[0046] Both the printing component 80 and the first detection component 100 are mounted on the first adjustment seat 703 and are located on one side of the peeling plate 706, so that printing is performed first, then the printing quality is checked to see if it meets the standard, and then the label is peeled off.

[0047] The detection components are located at the front end and / or rear end of the label pressing component 90. In this embodiment, the detection components include a first detection component 100 and a second detection component 110.

[0048] The first detection component 100 is positioned between the printing component 80 and the label pressing component 90 to detect the printing quality of the labels. When the printed label image has defects such as blurriness or repeated printing, the display control module 30 can determine that the label is a defective product. At this time, the display control module 30 can control the product 20 on the conveying component 50 to pause briefly before reaching the labeling position. The defective label cannot be pasted onto the product 20 and will move with the base film to the take-up roll, thereby completing the rejection of the printed defective product and preventing it from entering the pasting process.

[0049] The second detection component 110 is positioned between the label pressing component 90 and the rejection component 120 to detect the label pasting quality. When issues such as missing or excessive labels occur, the display control module 30 can control the rejection component 120 to reject them.

[0050] The first detection component 100 and the second detection component 110 are preferably visual inspection instruments. The visual inspection instrument is used to capture images of the printed label and the label affixed to the product 20, and send them to the display control module 30. The display control module 30 compares the captured images with preset stored standard images to determine whether the product is defective.

[0051] To ensure the shooting effect, it is preferable to set a ring-shaped fill light on the first detection component 100 and the second detection component 110, and the ring-shaped fill light is arranged coaxially with the detection component.

[0052] The rejection assembly 120 is located at the rear end of the second detection assembly 110 and is used to reject defective labeled products. The rejection assembly 120 includes a jet head, a pipe (not shown in the figure), and an air supply device (not shown in the figure). The air supply device is connected to the jet head through the pipe and is used to supply gas at a preset pressure to the jet head. The jet head blows air onto the conveying surface of the conveying assembly 50, or blows air from one side of the conveying surface of the conveying assembly 50 to the other side, to blow away defective labeled products on the conveying surface.

[0053] In one embodiment, the jet nozzle can be positioned below the conveying surface of the conveying assembly 50, specifically inside the annular conveyor belt 503, with the jet nozzle arranged at an upward angle. When the defective product 20 moves above the jet nozzle, it can be blown into the material frame 130 using air pressure.

[0054] In another embodiment, the jet head is disposed on the first side of the conveying assembly 50 and arranged on the second side of the conveying assembly 50. When the defective product 20 moves to the position of the jet head, the defective product 20 can be blown into the material frame 130 by air pressure.

[0055] The label pressing assembly 90 includes a second up-down adjustment assembly 901, a second left-right adjustment assembly 902, a second adjustment seat 903, and a label pressing head 904. The second up-down adjustment assembly 901 and the second left-right adjustment assembly 902 respectively drive the second adjustment seat 903 to move up and down and left and right. The label pressing head 904 is disposed on the second adjustment seat 903. The label pressing head 904 includes a tripod 9041, a belt 9042, and a power unit 9043. The belt 9042 is wound around the outside of the tripod 9041. The power unit 9043 is preferably a motor, and the drive shaft of the power unit 9043 extends into the tripod 9041 to drive the belt 9042. The lower part of the label pressing head 904 has a horizontally extending working part, which is formed by the belt 9042 moving to the lower position of the tripod 9041.

[0056] After being labeled, the product 20 is conveyed by the conveying assembly 50, passes through the action part of the label pressing head 904, and rotates around its own axis under the action of the moving belt 9042, thereby making the label completely adhere to the peripheral wall of the test tube. In this embodiment, the length of the action part should be long enough to ensure that the belt 9042 can drive the product 20 to rotate at least once, preferably multiple times, to ensure that the label is firmly adhered.

[0057] In summary, through the above-mentioned configuration, the forward rotation of the feeding roller 2 is used to push out the products 20 one by one, and the reverse rotation of the unloading wheel 5 is used to push the excess products 20 piled up above the feeding roller 2 backward. On the one hand, this ensures that only one product 20 can pass through the material passage gap 7 at the same time, and on the other hand, it can effectively prevent multiple products 20 from stopping at the same time or even getting stuck. By setting the feeding cam 4, the free end 32 of the movable plate 3 is forced to swing up and down around the hinge end 31, which is conducive to guiding the products 20 in the fixed frame 1 and making it easier for the products 20 located on the movable plate 3 to move towards the feeding roller 2, thus preventing the products 20 from stopping in the fixed frame 1.

[0058] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
