Description

Technical Field

[0001] The present invention relates to the technical field of needle tube labeling, and in particular to a needle tube labeling device. Background Art

[0002] Syringes are common medical devices that consist of a needle tube. After being mass-produced, syringes, also known as syringe barrels, need to be labeled to distinguish them or provide an area for marking.

[0003] Generally, after the needles are mass-produced, they are sorted by technicians and placed one by one on a labeling table. A conveyor system is installed on the labeling table to move the needles to the labeling machine at the end of the table, where the label is applied to the needles.

[0004] Due to the large number of syringes produced in batches, technicians need to quickly sort the syringes and place them individually on the labeling table. The above-mentioned existing technology has at least the following shortcomings: 1. It consumes too much technicians, resulting in high labor costs and low and unstable production efficiency; 2. When the syringes are manually placed on the labeling table, there is a certain degree of error between the actual placement of the syringes and the theoretical position of the syringes. This can lead to significant differences in the placement of the labels on each syringe, affecting the appearance and hindering medical staff from quickly marking the labels.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] It should be noted that if the embodiments of the present invention involve directional indications, such as up, down, left, right, front, and back, the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] like Figures 1 to 19 As shown, a needle tube labeling device includes a needle tube conveying device 1, a needle tube loading device 2 and a needle tube labeling device 3; the needle tube conveying device 1 includes a conveying frame 11, and the conveying frame 11 is provided with a conveying motion structure and a conveying drive device 16 with a transmission connection, and the conveying motion structure has a discharge port 1231; the needle tube labeling device 3 includes a labeling conveying platform 31, the needle tube loading device 2 corresponds to the position of the discharge port 1231, and is located on the upper side or side of the labeling conveying platform 31, the needle tube loading device 2 includes a tube clamping device 22, a loading motion device 23 and a loading drive device 24, the tube clamping device 22 is provided on the loading motion device 23, and the tube clamping device 22 and the loading motion device 23 are both transmission-connected to the loading drive device 24, and the loading drive device 24 is used to drive the tube clamping device 22 and the loading motion device 23 to transport the needle tube 10 from the discharge port 1231 to the labeling conveying platform 31.

[0039] The needle conveying device 1 conveys the needle 10 to the discharge port 1231. The needle loading device 2 then clamps the needle 10 at the discharge port 1231 using the clamping device 22. The loading motion device 23 then moves the needle 10 to the labeling conveying platform 31. The needle 10 then enters the needle labeling device 3 for labeling. This process eliminates the need for technicians to be directly involved, reducing both technical staff and labor costs while maintaining a high and stable production efficiency.

[0040] In some specific embodiments, the conveying motion structure includes a vibrating conveying structure 12, the vibrating conveying structure 12 includes a vibrating disk 121, the vibrating disk 121 has a needle tube outlet 12113, the needle tube outlet 12113 is connected to the discharge port 1231, and the vibrating disk 121 is used to convey multiple needle tubes 10 to the needle tube outlet 12113 one by one, and when the needle tube 10 passes through the needle tube outlet 12113, the extension direction of the needle tube 10 is consistent with the direction of the needle tube outlet 12113.

[0041] In some specific embodiments, a needle tube conveying spiral channel 1211 is provided on the vibration disk 121, and the needle tube conveying spiral channel 1211 includes a needle tube side-turning conveying section 12111. The needle tube side-turning conveying section 12111 is close to the needle tube outlet 12113. A needle tube side-turning inclined surface 12112 is provided on the side wall of one side of the needle tube side-turning conveying section 12111. The needle tube side-turning inclined surface 12112 is connected to the bottom of the needle tube side-turning conveying section 12111. The angle between the needle tube side-turning inclined surface 12112 and the bottom of the needle tube side-turning conveying section 12111 is called angle θ. The angle θ gradually decreases from 180° to close to 90° along the conveying direction of the needle tube side-turning conveying section 12111, so that when the needle tube 10 passes through the needle tube outlet 12113, the ear plate 102 of the needle tube 10 extends in the vertical direction.

[0042] Specifically, the needle tube outlet 12113 is arranged on the needle tube conveying spiral channel 1211, and the conveying drive device 16 includes a vibration disk drive device, which drives the vibration disk 121 to move, so that the needle tube 10 in the vibration disk 121 is conveyed in the needle tube 10 spiral channel in an orderly manner.

[0043] The needle tube 10 is composed of a tube body 101 and an ear plate 102. The ear plate 102 is provided at one end of the tube body 101. The length d and width c of the ear plate 102 are both greater than the outer diameter b of the tube body 101, and the length d of the ear plate 102 is greater than the width c. Due to the inertia of placement, when the needle tube 10 is in the main disk body of the vibrating disk 121, the placement posture of its ear plate 102 can be roughly regarded as: the length direction of the ear plate 102 is in the horizontal direction, and the width direction of the ear plate 102 is in the vertical direction. When the needle tube 10 is transported from the main disk body to the entrance of the needle tube delivery spiral channel 1211, its ear plate 102 also maintains the above posture. Therefore, the width of the entrance of the needle tube 10 delivery bolt channel is slightly greater than the length of the ear plate 102, so that the needle tube 10 can enter the needle tube 10 delivery bolt channel, and only one needle tube 10 can pass through the entrance of the needle tube 10 delivery bolt channel at the same time.

[0044] The needle tube 10 is on the needle tube conveying spiral channel 1211 and must pass through the needle tube sideways conveying section 12111 before reaching the needle tube outlet 12113. Figures 5 to 7The angle between the needle tube side flip slope 12112 of the needle tube side flip conveying section 12111 and the bottom of the needle tube side flip conveying section 12111 is called the angle θ. Since the angle θ gradually decreases from 180° to close to 90° along the conveying direction of the needle tube side flip conveying section 12111, and the width of the needle tube side flip conveying section 12111 gradually narrows from slightly larger than the length of the ear plate 102 to slightly larger than the width of the ear plate 102, the outlet of the needle tube side flip conveying section 12111 only allows the needle tube 10 to pass through in the posture of "the width direction of the ear plate 102 is in the horizontal direction, and the length direction of the ear plate 102 is in the vertical direction". In the process of passing through the needle tube side-turning conveying section 12111, the needle tube 10 enters the needle tube side-turning conveying section 12111 with the "length direction of the ear plate 102 in the horizontal direction, and the width direction of the ear plate 102 in the vertical direction", and leaves the needle tube side-turning conveying section 12111 with the "width direction of the ear plate 102 in the horizontal direction, and the length direction of the ear plate 102 in the vertical direction".

[0045] In some specific embodiments, the vibration conveying structure 12 further includes a discharge guide groove 122, the extension direction of the discharge guide groove 122 is consistent with the direction of the needle tube outlet 12113, one end of the discharge guide groove 122 is connected to the needle tube outlet 12113, and the other end is a discharge port 1231; the bottom of the discharge guide groove 122 is provided with a needle tube positioning groove 1222 that can only accommodate the needle tube 10 tube body 101, and both sides of the needle tube positioning groove 1222 are provided with a tube support bar 1221, the extension direction of the needle tube alignment groove 1222 and the tube bar 1221 are consistent with the extension direction of the discharge guide groove 122, and the needle tube alignment groove 1222 passes through the bottom of the discharge guide groove 122, so that when the needle tube 10 passes through the discharge guide groove 122, the tube body 101 is inserted into the needle tube alignment groove 1222, the ear plate 102 is supported on the tube bar 1221, and the needle tube 10 is in a vertical extension posture with the pressing hand 103 on the top and the tube head 104 on the bottom.

[0046] Specifically, the length of the discharge guide groove 122 is greater than the length of the needle tube 10. The width a of the needle tube alignment groove 1222 is greater than the outer diameter b of the tube body 101 of the needle tube 10, but smaller than the width c of the ear plate 102 of the needle tube 10.

[0047] The discharge guide groove 122 is part of the vibrating conveying structure 12 , and the distance of the conveying needle tube 10 is the same as that of the vibration plate 121 . The conveying drive device 16 can vibrate the discharge guide groove 122 so that the needle tube 10 on the discharge guide groove 122 can move toward the discharge port 1231 .

[0048] The tube body 101 of the needle tube 10 has a tube head 104 at one end and a handle 103 at the other end, which is located near the ear plate 102. When the needle tube 10 leaves the needle tube outlet 12113, the end near the discharge port 1231 may be the tube head 104 or the handle 103. However, after the needle tube 10 has fully entered the discharge guide groove 122, the needle tube alignment groove 1222 can only accommodate the tube body 101 of the needle tube 10. In addition, under the action of gravity, whether the tube head 104 or the handle 103 end of the needle tube 10 is near the discharge port 1231, the tube body 101 of the needle tube 10 swings downward and passes through the needle tube alignment groove 1222, while the ear plate 102 of the needle tube 10 is supported on the tube bar 1221, so that the needle tube 10 is in a vertically extended posture with the handle 103 on top and the tube head 104 on the bottom.

[0049] The needle tube alignment groove 1222 extends all the way to the discharge port 1231, and the needle tube 10 reaches the discharge port 1231 in the posture of "the pressing hand 103 is on the top and the tube head 104 is on the bottom".

[0050] Furthermore, the vibration plate 121 includes two needle tube conveying spiral channels 1211 and two discharge guide grooves 122. The two needle tube conveying spiral channels 1211 are arranged side by side, and the two discharge guide grooves 122 are arranged side by side. The two discharge guide grooves 122 correspond to the two needle tube conveying spiral channels 1211 one by one.

[0051] The needle tube side-turning conveying section 12111 is provided on the needle tube conveying spiral channel 1211 so that when the needle tube 10 is positioned in the discharge guide groove 122 with the pressing handle 103 at the top and the needle head 104 at the bottom, the length direction of the lug plate 102 is aligned with the extension direction of the discharge guide groove 122, and the needle tube 10 is conveyed to the discharge port 1231 in this position. The lug plate 102 protrudes longer from the tube body 101 along its length, which helps the clamping device 22 securely clamp the lug plate 102, thereby securing the needle tube 10.

[0052] Furthermore, a needle tube placement groove 123 is provided between the discharge guide groove 122 and the discharge port 1231. The extension direction of the needle tube placement groove 123 is consistent with that of the discharge guide groove 122. The structure of the needle tube placement groove 123 is the same as that of the discharge guide groove 122, but the difference between the needle tube placement groove 123 and the discharge guide groove 122 is that it is not connected to the conveying drive device 16 and does not have the function of conveying the needle tube 10. After passing through the discharge guide groove 122, the needle tube 10 enters the needle tube placement groove 123, still maintaining the posture of "pressing hand 103 on top, tube head 104 on the bottom", and will rely on inertia to slide a certain distance to stop at a position close to the discharge port 1231, waiting to be clamped by the tube clamping device 22. The purpose of setting a needle tube placement groove 123 at one end between the discharge guide groove 122 and the discharge port 1231 is to prevent the needle tube 10 from rushing through the discharge port 1231 driven by the conveying drive device 16 and falling from the needle tube conveying device 1 before the tube clamping device 22 reaches the discharge port 1231.

[0053] In some specific embodiments, the needle tube conveying device 1 also includes a blowing device 15, which includes a blower 151 and a blowing tube 152. The blowing tube 152 is arranged on the side wall of the discharge guide groove 122, and the air outlet 1521 of the blowing tube 152 faces the discharge port 1231.

[0054] The air blowing device 15 is used to assist the needle tube 10 in the discharge guide groove 122 to move toward the discharge port 1231, so that the delivery of the needle tube 10 is smoother, which is beneficial to improving the delivery efficiency of the needle tube 10 and thus improving production efficiency.

[0055] In some specific embodiments, the needle tube conveying device 1 also includes a hopper 14, and the conveying motion structure also includes a feeding ladder 13. The lower end of the feeding ladder 13 is located in the hopper 14, and the upper end of the feeding ladder 13 is located above the vibrating disk 121. The feeding ladder 13 is used to convey the needle tube 10 in the hopper 14 to the vibrating disk 121.

[0056] In this embodiment, the hopper 14 can be used to receive the needle tubes 10 delivered from the needle tube 10 production and delivery device, and can also receive the needle tubes 10 manually placed in. The feeding ladder 13 transports the needle tubes 10 to the upper end of the vibrating plate 121 so that the needle tubes 10 can fall into the main plate body of the vibrating plate 121.

[0057] In some specific embodiments, the labeling conveyor 31 is located below the needle tube feeding device 2, the tube clamping device 22 is a clamping cylinder, the feeding drive device 24 includes a driving motor, the feeding motion device 23 includes a slider bearing 232, a slide rod 233 and a driving rod 231, the needle tube feeding device 2 also includes a feeding frame 21, the driving motor is arranged on the feeding frame 21, the driving rod 231 is perpendicular to the rotating shaft 241 of the driving motor, the two ends of the driving rod 231 are respectively a rotating end 2313 and a fixed end 2312, the fixed end 2312 of the driving rod 231 is fixedly connected to the rotating shaft 241 of the driving motor, a slide groove 2311 is provided on the driving rod 231, and the extension direction of the slide groove 2311 is consistent with that of the driving rod 231; the slider bearing 232 is rotatably connected to the feeding frame 21, the slide rod 233 is slidably connected to the slider bearing 232, one end of the slide rod 233 is provided with a clamping cylinder, and the other end is slidably connected to the slide groove 2311, so that:

[0058] When the rotating end 2313 is located directly below the fixed end 2312, the slider bearing 232 is located between the driving rod 231 and the discharge port 1231, the sliding rod 233 is perpendicular to the driving rod 231, and the clamping cylinder clamps the needle tube 10 out of the discharge port 1231;

[0059] When the rotating end 2313 starts to rotate in a direction away from the discharge port 1231, the clamping cylinder gradually moves away from the discharge port 1231;

[0060] When the driving rod 231 rotates to the fixed end 2312, the rotating end 2313 and the discharge port 1231 are arranged in sequence in the horizontal direction, the clamping cylinder is located below the driving rod 231, and the clamping cylinder loosens the needle tube 10 and places it on the labeling conveyor table 31.

[0061] Specifically, when the drive motor is mounted on the loading frame 21, its rotating shaft 241 extends horizontally, and the discharge port 1231 is also oriented horizontally, but the extension direction of the drive motor rotating shaft 241 is perpendicular to the direction of the discharge port 1231. The slider bearing 232 is rotatably connected to the loading frame 21, with its rotation axis parallel to the axis of the drive motor rotating shaft 241. The rotation axis of the slider bearing 232 is located on the side of the drive motor rotating shaft 241 closest to the discharge port 1231 and is lower than the drive motor rotating shaft 241. The loading drive device 24 also includes a cylinder drive device for driving the gripper cylinder to clamp or release the tube.

[0062] In this embodiment, the maximum rotation angle of the rotating shaft 241 of the drive motor is 270°, that is, the maximum rotation angle of the drive rod 231 is 270°: the rotation of the drive rod 231 270° from "the rotating end 2313 is directly below the fixed end 2312" to "the rotating end 2313 is located on the side of the fixed end 2312 close to the discharge port 1231" is called forward rotation. The rotation of the drive rod 231 270° from "the rotating end 2313 is located on the side of the fixed end 2312 close to the discharge port 1231" to "the rotating end 2313 is directly below the fixed end 2312" is called reverse rotation.

[0063] refer to Figures 10 to 14 , taking forward rotation as an example, the working process of the needle tube feeding device 2 is explained:

[0064] When the rotating end 2313 is directly below the fixed end 2312, the driving rod 231 is in a vertically extended position. The sliding rod 233 is now extended horizontally, and the connection between the sliding rod 233 and the driving rod 231 is located in the middle of the slide slot 2311. The clamping cylinder on the sliding rod 233 faces the discharge port 1231, and the cylinder drive device drives the clamping cylinder to clamp the ear plate 102 of the needle tube 10.

[0065] The driving motor drives the rotating shaft 241 and the driving rod 231 to rotate, and the rotating end 2313 gradually moves away from the discharge port 1231. The sliding rod 233 slides on the slider bearing 232. The end of the sliding rod 233 connected to the slide groove 2311 also slides in the slide groove 2311. The driving rod 231 drives the sliding rod 233 to move axially and away from the discharge port 1231 to avoid the discharge guide groove 122. This prevents the sliding rod 233 or the needle tube 10 on the clamping cylinder from touching the discharge guide groove 122 when the slider bearing 232 rotates.

[0066] After the driving rod 231 rotates to a certain angle, the end of the sliding rod 233 connected to the slide groove 2311 reaches the end of the slide groove 2311, and the driving rod 231 drives the slider bearing 232 to rotate until the driving rod 231 rotates 270° and is in a horizontal extension posture of "the rotating end 2313 is located between the fixed end 2312 and the discharge port 1231". The sliding rod 233 is in a vertical extension posture, and the clamping cylinder is located at the lower end of the sliding rod 233. The needle tube 10 on the clamping cylinder is also in a horizontal extension posture. The cylinder driving device can drive the clamping cylinder to release the ear plate 102 of the needle tube 10, so that the needle tube 10 falls on the labeling conveyor table 31.

[0067] After the needle tube 10 is loaded onto the labeling conveyor platform 31 from the discharge port 1231 , the driving rod 231 is reversed 270° so that the needle tube 10 is reset to the position where the rotating end 2313 is directly below the fixed end 2312 , preparing for the loading of the next needle tube 10 .

[0068] Furthermore, two clamping cylinders are provided at one end of the sliding rod 233 away from the driving rod 231. The two clamping cylinders correspond one-to-one to the two discharge guide grooves 122. When loading, the two clamping cylinders can clamp a needle tube 10 respectively, so that two needle tubes 10 can be loaded at the same time, which is beneficial to improving production efficiency.

[0069] In some other embodiments, the needle tube loading device 2 includes a loading frame 21, a drive motor, a rotating seat, a telescopic cylinder, and a clamping cylinder. The drive motor is arranged on the loading frame 21, and the rotating shaft 241 of the drive motor extends in the horizontal direction and is perpendicular to the direction of the discharge port 1231. The rotating seat is fixedly connected to the rotating shaft 241 of the drive motor, the cylinder body of the telescopic cylinder is fixed to the side of the rotating seat away from the drive motor, and the clamping cylinder is arranged on the piston rod of the telescopic cylinder. During loading, the clamping cylinder clamps the needle tube 10 on the discharge port 1231, and then the piston rod of the telescopic cylinder moves a distance toward the cylinder body to prevent the clamping cylinder or the needle tube 10 from touching the discharge guide groove 122 when the telescopic cylinder rotates. Then the drive motor drives the rotating seat to rotate to move the clamping cylinder with the needle tube 10 to the top of the labeling conveyor 31. Finally, the clamping cylinder releases the needle tube 10, so that the needle tube 10 falls on the labeling conveyor 31.

[0070] In some specific embodiments, a control system is also included, which is communicated with the needle tube conveying device 1, the needle tube loading device 2 and the needle tube labeling device 3; a needle tube sensor 1232 is provided on the needle tube conveying device 1, and the sensing end of the needle tube sensor 1232 is facing the discharge port 1231.

[0071] The needle tube sensor 1232 is used to sense whether a needle tube 10 is placed at the discharge port 1231. When the needle tube 10 is transported to the discharge port 1231, the sensor senses the needle tube 10. The control system receives the signal from the sensor and transmits the clamping signal to the needle tube loading device 2. The clamping device 22 clamps the needle tube 10.

[0072] In some specific embodiments, a control system is also included, which is communicated with the needle tube conveying device 1, the needle tube loading device 2 and the needle tube labeling device 3; the needle tube loading device 2 is provided with an empty position detector 34, and the detection end of the empty position detector 34 is facing the conveying surface of the labeling conveying platform 31.

[0073] The vacancy detector 34 detects whether there is a vacant space at the loading position of the needle tube 10 on the labeling conveyor 31. During the loading process, when the clamping cylinder is about to reach the loading position above the labeling conveyor 31, the drive motor temporarily stops and waits for the vacancy detector 34 to detect whether there is a vacant space at the loading position of the needle tube 10 on the labeling conveyor 31. If there is a needle tube 10 at the loading position, the drive motor waits for the labeling conveyor 31 to advance the needle tube 10. If there is no needle tube 10 at the loading position, i.e., there is a vacant space, the drive motor continues to drive the clamping cylinder to directly above the labeling conveyor 31, then the clamping cylinder releases, allowing the needle tube 10 to fall onto the labeling conveyor 31.

[0074] In some specific embodiments, a needle tube guide rod 33 is also provided on the labeling conveying platform 31, and a labeling conveyor belt is provided on the labeling conveying platform 31. The needle tube guide rod 33 is located on the side of the labeling conveying platform 31 close to the needle tube conveying device 1. The needle tube guide rod 33 extends as a whole along the conveying direction of the labeling conveying platform 31 and gradually approaches the labeling conveyor belt.

[0075] Specifically, a labeling conveyor belt is wound around the labeling conveyor platform 31. The conveyor belt is composed of multiple conveyor rods 311 arranged along the belt's extension and connected by connecting belts. The conveyor plate extends perpendicular to the conveying direction of the labeling conveyor belt. The conveying direction of the labeling conveyor belt is perpendicular to the direction of the discharge trough 122, and the conveyor rods 311 extend in the same direction. When the needle tube loading device 2 loads the needle tube 10 onto the labeling conveyor platform 31, it places the needle tube 10 between adjacent conveyor rods 311.

[0076] The needle tube labeling device 3 further includes a labeling machine 32, which is located above the labeling conveyor belt. The needle tube feeding device 2 and the labeling machine 32 are arranged in sequence along the conveying direction of the labeling conveyor belt.

All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
