[0002] With the development of the times, major companies are using visual inspection to replace low-end manual inspection products, and vacuum blood collection tubes are no exception. For example, in the process of making vacuum blood collection tubes, visual inspection is usually used to detect defects in the appearance of the tube body, and then the defective tube body is removed and supplemented with a new qualified tube body, and then the qualified tube body is transported to the carrier to avoid individual carriers lacking tube bodies, because solvents need to be added to the tube bodies on the carrier later, and such solvents generally have a certain degree of corrosiveness, so it is necessary to ensure that there are vacuum blood collection tubes at each workstation in the carrier, otherwise the solvent will corrode the carrier. The existing technology usually suspends the feeding device and then supplements the empty position with a new tube body, resulting in a decrease in the feeding efficiency of the tube body. In view of this, the utility model proposes a non-stop feeding device to solve the above problems. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A non-stop feeding device comprises a frame, wherein the frame is provided with a chain transmission mechanism for conveying a pipe body from front to back, the chain transmission mechanism is provided with a plurality of rollers at equal intervals, and two adjacent rollers are spaced apart to form a material trough for placing the pipe body; a material bin is provided above the chain transmission mechanism, and a first sensor for detecting whether a pipe body is placed in the material trough is provided in front of the material bin; a discharge port is provided at the bottom of the material bin, and a feeding mechanism is provided between the discharge port and the chain transmission mechanism; the feeding mechanism is used to put the pipe body into an empty material trough.

[0009] Preferably, the non-stop feeding device also includes a second dividing plate and a third sensor. The output shaft of the feeding motor passes through the axis of the second dividing plate and is connected to the axis of the unloading wheel. The second dividing plate rotates synchronously with the unloading wheel. The number of divisions of the second dividing plate is consistent with the number of tube grooves of the unloading wheel.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model determines whether there is a tube body placed in the material trough through the first sensor. If there is no tube body in the material trough detected by the first sensor, when the material trough without the tube body moves to the bottom of the feeding mechanism, the feeding mechanism puts the tube body into the empty material trough to achieve feeding, and the chain transmission mechanism does not need to be paused, thereby improving the feeding efficiency of the chain transmission mechanism.

[0024] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0025] Reference Figures 1 to 4 A non-stop feeding device includes a frame 1, and the frame 1 is provided with a chain transmission mechanism 2 for conveying a tube body 01 from front to back. The chain transmission mechanism 2 is provided with a plurality of rollers 21 at equal intervals, and two adjacent rollers 21 are spaced to form a trough 22 for placing the tube body 01. A silo 3 is provided above the chain transmission mechanism 2. A first sensor 11 for detecting whether a tube body 01 is placed in the trough 22 is provided in front of the silo 3. A discharge port is provided at the bottom of the silo 3, and a feeding mechanism 4 is provided between the discharge port and the chain transmission mechanism 2; the feeding mechanism 4 is used to put the tube body 01 into the empty trough 22.

[0026] like Figure 2 As shown, the chain transmission mechanism 2 includes a plurality of sprockets 23, two closed chains 24, and a motor assembly 25 for driving one of the sprockets 23 to rotate; connecting pins 211 are provided at both ends of the roller 21, and the closed chain 24 is formed by connecting links through the connecting pins 211; and the outer periphery of the sprocket 23 is evenly provided with cogs for engaging with the chain links.

[0027] The non-stop feeding device also includes a first indexing plate 26 and a second sensor 27. The axis of the first indexing plate 26 is connected to the axis of one of the sprockets 23, and the first indexing plate 26 rotates synchronously with the sprocket 23. The number of divisions set on the first indexing plate 26 is consistent with the number of cogs of the sprocket 23, and one cog corresponds to one trough 22, so the second sensor 27 detects that the number of divisions of the first indexing plate 26 rotated is equal to the number of troughs 22 conveyed backward by the chain transmission mechanism 2, and accurately determines the distance conveyed backward by the chain transmission mechanism 2.

[0028] The feeding mechanism 4 includes a feeding wheel 41 and a feeding motor 42. A plurality of tube grooves 411 for placing the tube body 01 are evenly arranged on the outer circumference of the feeding wheel 41. A limiting component 43 for limiting the tube body 01 from leaving the tube groove 411 is arranged on the front and / or rear side of the feeding wheel 41. The size of the discharge port is adapted to the size of a tube body 01. The tube groove 411 at the top of the feeding wheel 41 is opposite to the discharge port. The tube body 01 in the tube groove 411 at the bottom of the feeding wheel 41 is used to replenish the empty feeding trough 22.

[0029] like Figure 4 As shown, the non-stop feeding device also includes a second indexing plate 44 and a third sensor 45. The output shaft of the feeding motor 42 passes through the axis of the second indexing plate 44 and is connected to the axis of the unloading wheel 41. The second indexing plate 44 rotates synchronously with the unloading wheel 41. The number of divisions of the second indexing plate 44 is consistent with the number of pipe slots 411 of the unloading wheel 41, so when the second indexing plate 44 rotates one division, the unloading wheel 41 also releases a pipe body 01. The third sensor 45 is used to detect the division of the second indexing plate 44, accurately monitor the output shaft of the feeding motor 42 and the rotation angle of the unloading wheel 41, so as to accurately monitor the number of pipe bodies 01 released by the unloading wheel 41, and ensure that only one pipe body 01 is added to the empty trough 22.

[0030] The limiting component 43 is provided with an arc-shaped groove 431 for accommodating the front side or the rear side of the unloading wheel 41 , and the radius of the arc-shaped groove 431 is consistent with the radius of the unloading wheel 41 .

[0031] A fourth sensor 12 is provided behind the silo 3 to detect whether the tube 01 is placed in the trough 22. The non-stop feeding device also includes an alarm mechanism, which is used to sound an alarm when the fourth sensor 12 detects that the trough 22 does not contain the tube 01.

[0032] In the present invention, along the front-to-back direction, the distance between the tube groove 411 at the bottom of the unloading wheel 41 and the first sensor 11 is N material grooves 22. In the present invention, the control system is controlled, and the control system controls the start or stop of the chain transmission mechanism 2, the alarm mechanism, and the feeding mechanism 4 according to the signals detected by each sensor.

[0033] The refilling process of the utility model is as follows: First, the first sensor 11 detects that the corresponding trough 22 is an empty trough (a trough 22 without a tube body 01), and the refilling mechanism 4 is ready to refill the empty trough. When the first sensor 11 detects that the empty trough is immediately detected, the second sensor 27 detects that the first indexing plate 26 has rotated N divisions, and the empty trough 22 moves to the bottom of the unloading wheel 41. At the same time, the third sensor 45 detects that the second indexing plate 44 has rotated one division, and the unloading wheel 41 is driven by the refilling motor 42 to put the tube body 01 into the empty trough 22. Since the tube trough 411 at the bottom of the unloading wheel 41 is very close to the trough 22, the tube body 01 of the unloading wheel 41 quickly falls into the trough 22. Then the fourth sensor 12 detects whether the empty trough 22 is replenished with the tube body 01. If it is detected that there is no tube body 01 in the trough 22, the control system stops the entire refilling device, and the alarm mechanism sounds an alarm, and refilling is performed manually.

[0034] The utility model detects the empty material trough 22 through the first sensor 11, and the feeding mechanism 4 puts the tube body 01 into the empty material trough 22 to realize automatic feeding, and the chain transmission mechanism 2 hardly needs to be paused, thereby improving the feeding efficiency of the chain transmission mechanism 2.

[0035] The non-stop feeding device further includes a fifth sensor 31. The silo 3 is provided with a window 32. Specifically, the window 32 is located at a position lower than half of the height of the silo 3. The fifth sensor 31 is used to detect whether there is a tube body 01 at the window 32. When the fifth sensor 31 detects that there is no tube body 01 at the window 32, the alarm mechanism sounds an alarm to remind the replenishment of the tube body 01 of the silo 3, so as to avoid the lack of the tube body 01 in the silo 3 affecting the feeding mechanism 4 to put the tube body 01.

[0036] The width of the inner cavity of the silo 3 along the front-to-back direction is adapted to the outer diameter of the tube body 01, and the width of the inner cavity of the silo 3 along the left-to-right direction is adapted to the length of the tube body 01. The tube bodies 01 are stacked one by one in the silo 3 along the vertical direction, and the discharge port is opposite to the tube groove 411 located at the top of the unloading wheel 41. The tube bodies 01 in the silo 3 can be replenished to the tube groove 411 of the unloading wheel 41 in an orderly manner.

[0037] like Figure 1 As shown, the first sensor 11 is mounted on the frame 1 through the first bracket 13 , the fourth sensor 12 is mounted on the frame 1 through the second bracket 14 , and the first indexing plate 26 and the second sensor 27 are mounted on the frame 1 through the third bracket 15 .
