[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1:

[0025] like Figures 1 to 3 As shown, a pre-filled needle horizontal conveyor line includes a conveyor belt 1 and a motor 22 connected to the conveyor belt 1, a feed fence 18 is provided on one side of the conveyor belt 1, a discharge fence 20 is provided on the other side of the conveyor belt 1, a connecting fence 19 is provided between the feed fence 18 and the discharge fence 20, a detection photoelectric is provided above the conveyor belt 1, the conveyor belt 1 includes a single-layer pulley 3, a double-layer pulley 9 and a pulley mechanism, the single-layer pulley 3 and the double-layer pulley 9 are driven by the pulley mechanism, the pulley mechanism includes a round belt 7 and a linked round belt 8, the motor 22 is connected to an arc bevel gear reducer 21, and also includes an adjustment mechanism, the adjustment mechanism includes an adjustment positioning seat 24 arranged at the bottom end of the conveyor belt 1, a slider positioning seat 23 connected to the adjustment positioning seat 24 and a linear guide 16, the linear guide 16 is slidably connected to the slider positioning seat 23, the longitudinal movement of the slider positioning seat 23 is controlled by the adjustment positioning seat 24, thereby changing the width of the conveyor belt 1 to adapt to pre-filled needles of different preset specifications.

[0026] When in use, first the motor 22 is started, driving all the round belts 7 to start conveying synchronously; the pre-filling needle enters the entrance of the conveyor belt 1, and the feed detection photoelectric 6 detects that it is in place; the pre-filling needle is transported to the outlet and enters the middle connecting fence 19, and the positions of the two middle connecting fences 19 are staggered to ensure that the round belt 7 drives the pre-filling needle to be conveyed at any position of the entire conveyor line; the middle detection photoelectric 10 has the function of bottle blockage detection and counting, and the discharge detection photoelectric 11 can detect the pre-filling needle leaving the conveyor belt 1; the width of the conveyor belt 1 can be adjusted by the knob 12, so that the conveyor belt 1 can adapt to all pre-filling needles with diameter specifications of 6.85mm-14.45mm.

[0027] In practical applications, the double-layer pulley 9 is arranged on a side close to the connecting fence 19 , and the double-layer pulley 9 is connected to the single-layer pulley 3 through a round belt 7 .

[0028] In practical applications, any laterally adjacent double-layer pulleys 9 are connected via a linkage round belt 8 .

[0029] In practical applications, the linear guide rail 16 is connected to a guide rail mounting seat 17 .

[0030] In practical applications, the motor 22 is a speed-adjustable motor, which drives the bevel gear reducer 21 to output to the two round belts 7.

[0031] In practical applications, the motor 22 is connected to the arc bevel gear reducer 21. Through the arc bevel gear reducer 21, one input and two outputs are realized, and all the round belts 7 on the entire conveyor belt 1 move synchronously, avoiding the error of independent movement of multiple motors 22 causing friction between the belt and the pre-filling needle.

[0032] In actual applications, the detection photoelectric includes feed detection photoelectric 6, intermediate detection photoelectric 10 and discharge detection photoelectric 11. The feed detection photoelectric 6 is set on the side close to the feed fence 18, the intermediate detection photoelectric 10 is set on both sides of the connecting fence 19, and the discharge detection photoelectric 11 is set on the side close to the discharge fence 20.

[0033] In practical applications, the number of the intermediate detection photoelectric sensors 10 is 2. The intermediate detection photoelectric sensors 10 play the role of bottle blockage detection and counting.

[0034] In practical applications, the pulley mechanism also includes a bearing base 5, a deep groove ball bearing 4, and a bearing cover 2. The pulley mechanism is small in size, easy to clean, has a high rated speed, a low friction coefficient, and a low load on the motor 22.

[0035] In practical applications, the adjustment mechanism further includes a knob 12 , an adjustment screw 15 connected to the knob 12 , and a thrust ball bearing 14 matched with the adjustment screw 15 .

[0036] In practical applications, a digital display 13 for displaying the adjustment width of the knob 12 is provided between the knob 12 and the adjusting screw 15. The digital display 13 can display the width adjusted by the knob 12.

[0037] For prefilled needles with diameters of 6.85 mm, 8.15 mm, 10.85 mm and 14.45 mm, the delivery speed of the present invention can reach 3000, 2600, 1900 and 1400 needles per minute at the fastest.

[0038] The round belt 7 is divided into a driving round belt 7 and a driven round belt 7. The driving round belt 7 is connected to the motor 22.

[0039] Since the conveyor belt 1 is too long, a mechanism of active round belt 7-interlocking belt-driven round belt 7 is adopted to reduce costs. The two pulley mechanisms connecting the fence 19 adopt double-layer pulleys 9, the upper layer connects the active round belt 7 and the driven round belt 7, and the lower layer connects the two double-layer pulleys 9; since there is no round belt 7 on the upper layer of the connecting fence 19, the two connecting fences 19 are staggered so that the round belt 7 contacts the pre-filled needle flange at any position of the entire conveyor belt 1.

[0040] If the conveying speed needs to be increased later, the motor 22 and the reducer can be replaced; if the length of the conveyor belt 1 needs to be increased later, it can be achieved by increasing the length of the round belt 7, the feed fence 18 and the discharge fence 20; the present invention uses the round belt 7 to convey the pre-filled needles, and due to the material properties of the round belt 7 itself, no belt tensioning mechanism is required.

[0041] The beneficial effects of the present invention are as follows: by adjusting the knob 12, the adjusting screw 15 is rotated to cooperate with the thrust ball bearing 14. At the same time, all the adjustment positioning seats 24 on one side of the conveyor line are equipped with a linear guide rail 16. The longitudinal movement of the slider positioning seat 23 is controlled by adjusting the positioning seat 24, thereby changing the width of the conveyor belt 1 to adapt to pre-filled needles of different diameters; the pulley mechanism is small in size, easy to clean, has a high rated speed, a low friction coefficient, and a low load on the motor 22; a speed regulating motor 22 realizes one input and two outputs through an arc bevel gear reducer 21, and all the round belts on the entire conveyor belt move synchronously, avoiding the friction between the belt and the pre-filled needle caused by the error of independent movement of multiple motors.

[0042] Embodiment 2:

[0043] like Figure 4 As shown, a method for horizontal delivery of prefilled needles:

[0044] S1: Select the specifications of the prefilled needle and determine the delivery speed;

[0045] Select and confirm the prefilled needle diameter specification and delivery speed.

[0046] S2: Adjust the width of the delivery device according to the specifications of the prefilling needle;

[0047] Adjust the width of the delivery device according to the diameter specifications of the prefilled needle to accommodate the prefilled needle specifications.

[0048] S3: installing the prefilled needle on a delivery device and transporting it;

[0049] The prefilling needle is mounted on a conveying device (such as a conveyor belt), and the motor 22 is started. The motor 22 drives the round belt 7 to rotate, so that the prefilling needle is conveyed.

[0050] S4: Perform multiple photoelectric detections on the prefilled needles in transportation;

[0051] The detection photoelectric includes a feed detection photoelectric, an intermediate detection photoelectric 10 and a discharge detection photoelectric 11.

[0052] When the prefilling needle enters the inlet of the conveying equipment, the feed detection photoelectric detection detects that it is in place;

[0053] When the prefilling needle enters the middle section of the conveying device, the intermediate detection photoelectric 10 detects that it is in place, and the intermediate detection photoelectric 10 plays the function of bottle blockage detection and counting.

[0054] S5: When any photoelectric detection fails to detect the prefilling needle, the conveying device stops running after idling for one cycle.

[0055] When all photoelectric detections have no signal (any photoelectric detection does not detect the prefilling needle), the delivery device stops delivering after idling for one cycle.

[0056] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
