Description

Technical Field

[0001] This utility model relates to the field of blood collection tube production, specifically to an automatic material handling device for plastic caps of blood collection tubes. Background Technology

[0002] Currently, blood collection tube caps typically use a vibratory feeder for material handling. The vibratory feeder hopper has a pulse electromagnet underneath, which causes the hopper to vibrate vertically. An inclined spring plate drives the hopper to oscillate around its vertical axis. Due to this vibration, the parts inside the hopper rise along a spiral track. During this ascent, they undergo a series of selections or posture changes along the track, allowing them to automatically enter the assembly or processing position in a uniform state according to assembly or processing requirements.

[0003] However, the vibratory feeder only has two vibration grooves, and can only process about 200 plastic caps for blood collection tubes per minute, which is inefficient. In addition, since the vibratory feeder is pot-shaped, the space is limited and the material storage is not large, so it is necessary to keep adding material, which is time-consuming, labor-intensive, and noisy. Utility Model Content

[0004] Based on the above description, this utility model provides an automatic material handling device for blood collection tube plastic caps to solve the problems of low material handling efficiency of vibratory plate and the need for material feeding in related technologies.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a recycling box is provided below the connection between the selection box and the material handling box, and the recycling box is connected to the hopper through a recycling pipe.

[0008] Furthermore, the lifting mechanism is connected to the hopper.

[0009] Furthermore, the lifting mechanism includes: a lifting track, which is inclined upward, and the lower end of the lifting track is disposed inside the hopper; and a hoist connected to the lifting track, which is used to drive the hoist to move the plastic cap of the blood collection tube.

[0010] Furthermore, the lifting track is provided with multiple horizontally spaced material placement plates.

[0011] Furthermore, the channel includes a first channel body and a second channel body, the second channel body being connected to the front end of the first channel body and located below the first channel body.

[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0024] This utility model provides an automatic material handling device for plastic caps of blood collection tubes, which can solve the problems of low material handling efficiency of vibratory feeders and the need for material feeding in related technologies.

[0025] See Figure 1 As shown in the figure, an automatic feeding device for blood collection tube plastic caps provided in this embodiment of the utility model includes: a lifting mechanism 1 for lifting blood collection tube plastic caps; a feeding mechanism 2 disposed below the lifting mechanism 1, the feeding mechanism 2 including: a cap selection box 21, which has multiple parallel grooves 22, the grooves 22 being straight grooves, a cap selection vibrator 25 installed at the bottom of the cap selection box 21, the vibrator working principle being to achieve fixed-point vibration of the object using the vibration principle, the cap selection box 21 having a detection window; a feeding box 23 disposed in front of the cap selection box 21, a feeding vibrator 24 installed at the bottom of the feeding box 23; and an outlet flow channel 3 disposed at the front end of the feeding box 23 for connecting to the main unit's feed inlet. In this embodiment, the plastic caps can be initially sorted by the cap selection box 21 and conveyed to the sorting box 23. The sorting box 23 further sorts the materials and conveys them to the outlet channel 3. Finally, the materials enter the main unit through the outlet channel 3. Since the channel 22 of the cap selection box 21 is straight and has multiple channels, a large number of plastic caps can be sorted at the same time, which greatly improves the work efficiency. In addition, the plastic caps are automatically lifted by the lifting mechanism 1, eliminating the need for manual feeding, saving time and effort, and reducing noise.

[0026] See Figure 1 and Figure 2 As shown, in some embodiments, a recycling box 26 is provided below the connection between the cap selection box 21 and the sorting box 23. The recycling box 26 is connected to the hopper 28 through a recycling pipe. In this embodiment, the cap selection box 21 and the sorting box 23 are connected by a square tube (not shown in the figure). One side of the square tube has a through hole. After the plastic caps are sorted by the cap selection box 21, the plastic caps in the upright state can pass through the square tube. The plastic caps in the horizontal state that have not been sorted will leak out through the through hole when passing through the square tube and fall into the recycling box 26, and then return to the hopper 28, so that the plastic caps that have not been sorted can be screened out.

[0027] See Figure 1As shown, in some embodiments, the lifting mechanism 1 is connected to the hopper 28. In this embodiment, the lifting mechanism 1 lifts the plastic caps from the hopper 28 for material sorting. The hopper 28 can hold a large number of plastic caps without frequent material replenishment. Plastic caps that have not been sorted are screened out and returned to the hopper 28 for re-sorting, thus achieving automated material sorting of plastic caps.

[0028] See Figure 1 and Figure 3 As shown, in some embodiments, the lifting mechanism 1 may include: a lifting track 11, which is inclined upward, and the lower end of the lifting track 11 is disposed in the hopper 28; a hoist 12, which is connected to the lifting track 11, and the hoist 12 is used to drive the blood collection tube plastic cap to move. The lifting track 11 is provided with multiple horizontally spaced material placement plates 13. In this embodiment, the upper end of the lifting track 11 is connected to the cap selection box 21 through a pipe. The hoist 12 can drive the lifting track 11 to move upward, and the material placement plates 13 on the lifting track 11 can drive the plastic cap in the hopper 28 to rise and finally enter the cap selection box 21, saving manpower and improving efficiency.

[0029] See Figure 2 As shown, in some embodiments, the channel 22 includes a first channel body 221 and a second channel body 222. The second channel body 222 is connected to the front end of the first channel body 221 and is located below the first channel body 221. In this embodiment, the first channel body 221 and the second channel body 222 correspond one-to-one. When the plastic cap enters the first channel body 221, it is mostly in a horizontal position. When it enters the second channel body 222 from the first channel body 221, the height difference between the first channel body 221 and the second channel body 222, combined with the vibration of the cap straight vibrator 25, makes the plastic cap stand upright, thus achieving the purpose of preliminary material sorting.

[0030] See Figure 2 As shown, in some embodiments, both the first trough 221 and the second trough 222 are provided with at least six troughs. By providing at least six troughs, 600-700 pieces of material can be processed per minute, greatly improving work efficiency. In other embodiments, the number and shape of the troughs can also be set according to actual needs.

[0031] See Figure 1As shown, in some embodiments, the material sorting box 23 is provided with a material sorting plate 29, which is arc-shaped. The front end of the material sorting plate 29 is connected to the outlet flow channel 3. The front end of the material sorting plate 29 is provided with a material sorting wheel 27, which is located at the inlet of the outlet flow channel 3. In this embodiment, the material sorting box 23 is provided with multiple forks (not shown in the figure) at one end near the cap selection box 21, which can further sort the plastic caps so that the plastic caps can be in a uniform state (vertical state) according to the assembly requirements. The bottom of the material box 23 near the cap selection box 21 has an opening. Plastic caps with the wrong size will fall into the recycling box 26 through the opening, while those with the correct size can continue to move forward. By the difference in diameter of the plastic caps, the required correct caps are selected, and the plastic caps are further sorted so that they can enter the assembly machine according to the assembly requirements. After sorting, the plastic caps move along the sorting plate 29 to the outlet, and then enter the outlet flow channel 3 in sequence under the push of the sorting wheel 27, and enter the assembly equipment for assembly, saving time and effort.
