Description

Technical Field

[0001] The present application relates to a diverting feeding device for discharging materials from a syringe. Background Art

[0002] There are three main types of syringe discharge and delivery in the prior art: washboard type discharge (patent number 201020580581.8), soft belt type discharge (patent number 201320636995.1), and screw type discharge (patent number 201720637284.4). The discharge methods are that the syringe first falls from a vertical state to a horizontal state on the slideway and falls into the placement slot. These methods are prone to cause syringe jamming and damage, and the efficiency is relatively low. Summary of the invention

[0003] The technical problem solved by the present application is to overcome the above-mentioned deficiencies in the prior art and to provide a steering feeding device with a simple structure, smooth discharge and conveying, high efficiency and not prone to damage, so as to solve the technical problem that the syringe is not stable and reliable enough when falling into the placement groove.

[0004] The technical solution adopted by the present application to solve the above-mentioned technical problems is: a steering feeding device for syringe discharge, including a synchronous belt, a synchronous wheel structure, a driving device, a syringe placement block, and a slideway, the driving device is connected to the synchronous wheel structure, the synchronous belt is installed on the synchronous wheel structure, and a syringe placement block is arranged on the synchronous belt, wherein the synchronous wheel structure is inclined forward, the syringe placement block is composed of a syringe placement portion and a tapered portion connected as one body, the tapered angle of the tapered portion is the same as the inclination angle of the synchronous wheel structure, the slideway is composed of slide rails on both sides, the tail boss of the syringe barrel on the slideway is hung on the slide rails on both sides and arranged vertically, the slideway outlet cooperates with the syringe placement portion moved to the slideway outlet, and a material baffle is provided from the slideway outlet to the end position of the syringe angle change.

[0005] The syringe placement portion is composed of a syringe boss 1, a syringe boss 2, and a rectangular connecting block. The rectangular connecting block is connected to the tapered portion. The syringe boss 1 has a block 1, a syringe barrel tail placement groove, and a boss 1 inclined surface. The block 1 and the syringe barrel tail placement groove are used for hanging and / or positioning the syringe tail, and the boss 1 inclined surface is used to guide the syringe tail to slide into the syringe placement portion; the syringe boss 2 has a block 2, a syringe barrel head placement groove, and a boss 2 inclined surface. The block 2 and the syringe barrel head placement groove are used for positioning the syringe head, and the boss 2 inclined surface is used to guide the syringe head to slide into the syringe placement portion. Since the syringe boss 1 and the syringe boss 2 are only located at the head and tail ends of the syringe barrel, there is no obstacle in the middle, which is convenient for the robot to suck or clamp the syringe.

[0006] The synchronous wheel structure is composed of a driving wheel and a driven wheel. The driving device adopts a servo motor, which is connected to the driving wheel. The synchronous belt is mounted on the driving wheel and the driven wheel. The center lines of the driving wheel and the driven wheel are on the same plane and are tilted forward at the same angle.

[0007] The baffle plate includes two arc-shaped baffles from the starting position to the ending position of the syringe angle change and a front baffle plate from the slideway exit to the starting position of the syringe angle change, ensuring that the syringe that slides vertically into the syringe placement part does not deviate or slide off.

[0008] The conical angle of the conical portion and the inclination angle of the synchronous wheel structure are both 45 degrees.

[0009] Compared with the prior art, the present application has the following advantages and effects: the structure is simple, so that the syringe in the vertical state in the slide falls into the placement groove and remains in the vertical state, and then the syringe is placed in a horizontal state through the steering mechanism, so that the discharge process is smoother and more efficient, and the syringe is not easily damaged.

[0013] The present application is further described in detail below with reference to the accompanying drawings and examples. The following examples are explanations of the present application and the present application is not limited to the following examples. Figure 2 The left is the front, and the right is the back (referring to the left and right before turning forward).

[0014] See also Figure 1 to Figure 3 The embodiment is provided with a synchronous belt 1, a synchronous wheel structure 2, a driving device 3, a syringe placement block 4, a slideway 6, and a material blocking plate 7. The syringe 5 described in the present application (the syringe may be provided with a needle or without a needle) is arranged vertically (the tail of the syringe 5 is on the top and the head is on the bottom) on the slideway 6, and the rear end outlet of the slideway 6 (the slideway 6 is arranged obliquely, and its rear end is the lower end, Figure 1The right side. It can also move horizontally or upwards by power) cooperates with the syringe placement block 4 set on the synchronous belt 1. The syringe placement block 4 is composed of two parts connected together. One is the syringe placement part 41 for placing the syringe 5 (composed of the syringe boss 1 411, the syringe boss 2 412, and the rectangular connecting block 413, and the rectangular connecting block 43 is connected to the tapered part 42), and the other is the tapered part for adjusting the angle of the syringe 5 (referring to the tapered surface between the connection surface with the rectangular connecting block 43 and the connection surface with the synchronous belt 1, so The cone angle of the cone portion refers to the angle between the connecting surface of the cone portion and the rectangular connecting block 413 and the connecting surface of the cone portion and the synchronous belt 1) 42, the slideway 6 is composed of two side rails 61, and the syringe 5 is hung on the two side rails 61 of the slideway 6 by the boss 511 at the tail of the barrel 51 (the middle of the two side rails 61 is hollow, and the rest of the syringe 5 except the boss 511 at the tail of the barrel 51 does not contact the two side rails 61) under the action of gravity, it naturally falls and slides. When a syringe 5 slides down the slideway 6, if the synchronous belt 1 is on the synchronous wheel structure 2 ( The driving device 3 of the present application adopts a servo motor, and can also be implemented by other power mechanisms. The rotation of the machine drives the driving wheel 21 to rotate counterclockwise, and the synchronous belt 1 is mounted on the synchronous wheel structure 2, thereby driving the synchronous belt 1 to rotate around the driving wheel 21 and the driven wheel 22. Since the driving wheel 21 and the driven wheel 22 of the present application are relatively arranged, the center lines of the driving wheel 21 and the driven wheel 22 are on the same plane and the upper sides are inclined at the same inclination angle θ (45 degrees in this embodiment) toward the slideway 6. The inclination angle θ is the same as the cone angle of the tapered portion 42. Therefore, the driving wheel 21 drives the syringe 5 in a syringe placement block 4 on the synchronous belt 1 from Figure 2 The syringe angle changes from the starting position 9 (at this time the syringe 5 is vertically downward) to the starting position 9 (at this time the syringe 5 is vertically downward) and rotates 180 degrees around the driving wheel 21 to Figure 2 When the syringe angle changes to the end position 10 (at this time, the center line of the syringe 5 just becomes horizontal), the syringe 5 which was originally in a vertical state is just converted to a horizontal state (the same is true for clockwise).

[0015] The syringe boss 1 411 of the syringe placement part 41 described in the present application has a block 1 4111, a syringe barrel tail placement groove 4112, and a boss 1 inclined surface 4113, wherein the block 1 4111 and the syringe barrel tail placement groove 4112 are used for hanging and / or positioning the tail of the syringe 5, and the boss 1 inclined surface 4113 is used to guide the tail of the syringe 5 to slide into the syringe placement part 41; the syringe boss 2 412 has a block 2 4121, a syringe barrel 51 head placement groove 4122, and a boss 2 inclined surface 4123, wherein the block 2 4121 and the syringe barrel head placement groove 4122 are used for positioning the syringe 5 head, and the boss 2 inclined surface 4123 is used to guide the syringe 5 head to slide into the syringe placement part 41.

[0016] The baffle plate 7 at least includes two arc-shaped baffles 72 in the section from the syringe angle change starting position 9 to the syringe angle change ending position 10. If there is a distance from the exit of the slide 6 to the syringe angle change starting position 9, a front baffle plate 71 is also required from the exit of the slide 6 to the syringe angle change starting position 9 to ensure that the syringe 5 vertically sliding into the syringe placement part 41 does not deviate or slip. The synchronous belt 1 leaves the driven wheel 22 and moves to the driving wheel 21 to the exit of the slide. There are no syringes on the syringe placement blocks 4 on this part of the synchronous belt 1. The syringe placement parts 41 of these syringe placement blocks 4 without syringes are arranged downward. See Figure 1 The synchronous belt 1 has four positions in total. The first is the front position 11 of the synchronous belt 1, the second is the rear position 12 of the synchronous belt 1, the third is the active side of the synchronous belt 1 and the active wheel 21, and the fourth is the driven side of the synchronous belt 1 and the driven wheel 22. The front and rear positions of the synchronous belt 1 are both inclined by 45 degrees. The cone angle of the conical portion 42 in the syringe placement block 4 on the synchronous belt 1 is 45 degrees. When the syringe placement blocks 4 without syringes move to the exit of the slide 6, the syringe 5 slides vertically into the syringe placement portion 41, and the tail boss 511 of the barrel 51 of the syringe 5 is suspended on the outside of the syringe boss 411 (the inside and outside here are relative to the syringe placement portion 41. At this time, the syringe state is referred to Figure 2 At the starting position 9 of the syringe angle change, the head of the barrel 51 rests on the syringe boss 2 412 and is blocked by the material blocking plate 7 to prevent it from falling. When the syringe 5 starts to rotate toward the rear of this embodiment around the central axis of the driving wheel 21, the syringe boss 2 412 is gradually lifted. After rotating 180 degrees, the center line of the syringe 5 is just parallel to the horizontal plane and is supported by the syringe boss 1 411 and the syringe boss 2 412. Figure 2 The syringe angle changes to the end position 10. The syringes 5 on the rear position 12 of the synchronous belt 1 are all in a horizontal state, which is convenient for the robot (not shown in the figure, in fact, these syringes 5 are taken out before they move to the driven wheel 22) to grab them for subsequent packaging steps.

[0017] The embodiment of the present application only needs to ensure that the syringe 5 in the slideway 6 can slide into the syringe placement part 41 vertically (or nearly vertically, for example, the angle between the syringe 5 and the horizontal plane in the front-to-back direction is between 90±5 degrees after the syringe 5 slides into the syringe placement part 41 and when the syringe 5 moves to the starting position 9 of the syringe angle change), so as to solve the technical problems that the syringe 5 is easily stuck, damaged, and the material dropping state is unstable, without the need for the syringe placement part 41 to be horizontal after rotating 180 degrees, as long as the syringe 5 located on the syringe placement part 41 does not affect the robot's placement, so the inclination angle of the synchronous belt 1 does not have to be 45 degrees. For example, if the syringe placement part 41 at the rear position 12 of the synchronous belt 1 is tilted 30 degrees so that the robot can grab it, the center line of the driving wheel 21 and the driven wheel 22 can be tilted forward 30 degrees, and the cone angle of the conical part 42 is 30 degrees, which can also achieve the purpose of the invention of the present application.

[0018] When the syringe of the present application falls into the syringe placement part 41, its center of gravity is on its vertical symmetrical axis, and the falling state is stable; when the syringe of the prior art falls, its center of gravity is on the horizontal asymmetrical axis, and the state of falling into the syringe placement part 41 is unstable. The outer surface of the synchronous belt of the present application is provided with syringe placement blocks arranged continuously and evenly, and the syringe placement blocks can be set according to the actual needs and the size of the syringe barrel, so that the syringes on the synchronous belt are arranged neatly, and due to the inclined setting of the synchronous wheel structure 2 and the design of the tapered part 42, when the syringe moves to the rear position 12 of the synchronous belt 1, the syringe placement part 41 only supports the two ends of the barrel 51 by the syringe boss 1 411 and the syringe boss 2 412, and the middle of the barrel 51 is hollowed out, which is convenient for the manipulator to absorb or clamp the syringe, ensuring the continuous stability and high efficiency of the conveying process and avoiding the occurrence of syringe surface wear.

[0019] Any simple deformation or combination of the technical features and technical solutions of this application should be considered to fall within the protection scope of this application.
