Description

Assembly device for assembling aerosol products

Technical Field

The invention relates to the field of aerosol product production equipment, in particular to equipment for assembling an aerosol product.

Background

The aerosol consists of four components, including propellant, medicine, valve system and pressure container. The propellant is the motive force for spraying the drug and sometimes also acts as a drug solvent or diluent. The medicament is a raw material, and is liquid, semisolid or solid powder. The valve system comprises a common valve, a quantitative valve and a foam valve according to different products. The pressure-resistant containers are usually tinplate cans and aluminum cans.

The working principle of the aerosol is that the stock solution (active ingredient) and the liquefied gas or the compressed gas are filled into an aerosol tank at the same time and sealed by a valve. When the valve is used, the actuator is pressed down, the valve is opened, liquid phase substances in the tank are upwards pressed into the valve body through the liquid guiding pipe under the action of the pressure of the gas phase propellant, and then enter the valve core from the valve core metering hole to the actuator and are sprayed out from the nozzle.

The L-shaped actuator is different from an aerosol actuator of a generally cylindrical or conical configuration, and as its name implies, resembles an L-shape. As shown in fig. 1 and 2, one of the right-angled ends of the L-shaped actuator 710 is a fitting end connected to a valve 721 (or a valve element) of the gas tank 720, and the fitting end is provided with a receiving opening 711 having an equal diameter as the tank body of the gas tank, facilitating the insertion of the gas tank, and the other end is a spraying end including a spraying opening 712 and a nozzle provided in the spraying opening, and is normally covered on the spraying opening with a cover 721 when not in use. Because of the structural specificity, the optimal output state of the automatic feeder is that the assembly end is downward, namely the output direction is vertical downward, if the automatic feeder is adopted to feed the actuator, the unstable gravity center exists when the actuator outputs, and the output of the assembly end cannot meet the requirements of quick and accurate alignment in the synchronous feeding process with the aerosol can.

Therefore, in the present aerosol for L-shaped actuators, it is still necessary to manually install a gas tank filled with compressed gas into the opening of the actuator, then test-spray several times, detect whether the gas tank is filled with compressed gas, and finally cap the gas tank.

The examples in the embodiments are intended to illustrate the present invention and are not to be construed as limiting the present invention.

Reference in the specification to "one embodiment" or "an example" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

Examples:

as shown in fig. 3, there is shown an assembling apparatus for assembling an aerosol product comprising a gas tank 720 and an actuator 710 (see fig. 1 and 2 in detail), the gas tank 720 being provided with a valve 721 at one end, the actuator 710 being an L-shaped actuator 710, a receiving port 711 at one end and a jet port 712 at the other end. The assembling apparatus is used to complete the assembly by loading the end of the gas tank 720 with the valve 721 into the receiving port 711 of the actuator 710.

As shown in fig. 3, 7 and 8, the assembling apparatus includes a transfer table 100, an actuator feeding device 200, a gas tank feeding device 300 and an assembling mechanism 400 (the assembling mechanism is shown in fig. 8 and 9 in detail). The conveying table 100 is provided with at least one accommodating groove 120, the accommodating groove 120 is used for accommodating an actuator 710 with an accommodating opening 711 facing upwards, and the conveying table 100 is further used for sequentially moving the accommodating groove 120 to positions corresponding to the actuator feeding device 200, the gas tank feeding device 300 and the assembling mechanism 400, so that the actuator feeding device 200, the gas tank feeding device 300 and the assembling mechanism 400 can complete corresponding procedures, and finally, the gas tank 720 and the actuator 710 are assembled.

The actuator feeding device 200 is configured to set the actuator 710 such that the accommodating opening 711 of the actuator 710 is directed upward, and convey the actuator 710 into the accommodating groove 120 of the conveying table 100. Here, the station corresponding to the actuator feeding device 200, that is, the position where the actuator feeding device 200 finally outputs the actuator 710, is located above the accommodating groove 120 (moving route), so that after the actuator feeding device 200 outputs the actuator 710 with the accommodating opening 711 facing upward, the actuator feeding device 200 falls into the accommodating groove 120 located just below it after coming out.

The gas tank loading device 300 is configured to set the gas tank 720 in a state in which the valve 721 of the gas tank 720 is downward, and insert the gas tank 720 into the accommodating opening 711 of the actuator 710 when the conveying table 100 moves the actuator 710 with the accommodating opening 711 upward to a station corresponding to the gas tank loading device 300. Likewise, here the station corresponding to the gas tank charging device 300, i.e. the position at which the gas tank charging device 300 finally outputs the gas tank 720, is likewise located above the receiving groove 120 (movement path), so that the gas tank 720 with the output valve 721 of the gas tank charging device 300 facing downward falls exactly into the (receiving opening 711 of the) actuator 710 of the lower receiving groove 120.

The assembly mechanism 400 is configured to press the gas tank 720 with the valve 721 facing downward in the accommodating port 711 of the actuator 710 when the transfer table 100 moves the actuator 710 with the accommodating port 711 facing upward to a station corresponding to the assembly mechanism 400. Also, the station corresponding to the mounting mechanism 400 here, i.e., the position where the mounting mechanism 400 is disposed.

As shown in fig. 9, the assembly mechanism 400 includes a push rod 410 and a fixing frame 420 for fixing the push rod. The push rod is vertically arranged downwards, the push rod is located right above the accommodating groove 120 (moving route), when the accommodating groove 120 is located right below, the push rod is pressed aiming at the bottom of the air tank 720 in the accommodating opening 711 of the lower actuator 710, so that the air tank 720 and the actuator 710 are assembled, and meanwhile, the valve rod of the valve 721 of the air tank 720 can be triggered in the pressing process and the trial spraying is completed once, so that whether the air tank 720 contains reagents or not can be checked. According to circumstances, a plurality of pilot injections may be performed, a plurality of operations may be performed by a push rod of one assembly mechanism 400, or a plurality of assembly mechanisms may be sequentially provided, and pilot injections may be performed in a sequential manner, which is not limited herein.

According to the work stations arranged by the actuator feeding device, the gas tank feeding device and the assembling mechanism, and in consideration of actual working conditions, the conveying table can adopt various conveying modes. For example, the actuator feeding device, the gas tank feeding device and the assembling mechanism are sequentially arranged in a linear mode, the conveying table can adopt a synchronous belt, a clamp with a containing groove is arranged on the synchronous belt, and the clamp is conveyed and moved between stations. For example, the conveying table may also directly adopt an existing rotating disc structure, and then the stations of the actuator feeding device, the gas tank feeding device and the assembling mechanism may be sequentially arranged around the rotating disc, which is not limited herein.

The working principle of the assembly device provided in this embodiment is as follows: the assembly device changes the mode of installing the actuator on an upright gas tank in the existing manual assembly process during the assembly, but utilizes the actuator feeding device 200 and the gas tank feeding device 300 to respectively invert the actuator 710 and the gas tank 720, and then inserts the gas tank 720 into the accommodating opening 711 of the actuator 710 to complete the assembly, in the process, the gravity center of the inverted actuator 710 is lowered, and particularly, the operation requirement on the L-shaped special-shaped actuator 710 is lowered after the gravity center of the L-shaped special-shaped actuator 710 is lowered, so that the actuator can relatively and stably enter the accommodating groove 120 to be fixed, and then the gas tank 720 is assembled into the gas tank 720.

In this embodiment, the transfer table 100 will be described by taking the structure of the rotating disk 110 as an example. As shown in fig. 7 and 8, the conveying table 100 includes a rotating disc 110 and a driving device for driving the rotating disc 110 to rotate. The rotating disc 110 and the driving means are arranged on one work platform. The rotating disc 110 is rotatably arranged on the working platform, the rotating center is vertical to the working platform, for example, a vertical short shaft is arranged on the working platform, the lower end of the short shaft is fixed with the working platform, a shaft hole is arranged in the middle of the rotating disc 110, and the upper end of the short shaft is positioned in the shaft hole and is rotationally connected with the rotating disc 110 through a bearing. The driving device may adopt a motor and a reduction gear set for transmission or a synchronous belt for transmission according to the diameter and the rotation speed of the rotating disc 110, which is not limited herein.

The rotating disc 110 is provided with a plurality of accommodating grooves 120, the number of the accommodating grooves 120 can be flexibly set according to the number of stations, the completion time of each process, the rotating speed of the rotating disc 110 and other factors, but the number of the accommodating grooves 120 is generally larger than the number of the stations, so that after the rotating disc 110 rotates by a distance of one station, other stations can perform operations simultaneously. The rotating disc 110 in fig. 8 shows 16 accommodating grooves 120, the 16 accommodating grooves 120 are circumferentially and uniformly distributed on the rotating plane with the center of rotation as the center, and at most 16 stations can be arranged on the outer side of the rotating disc 110 according to the number of the accommodating grooves 120. The stations corresponding to the actuator feeding device 200, the gas tank feeding device 300 and the assembly mechanism 400 are sequentially arranged in the rotation direction (rotation direction) of the rotating disc 110, the rotation direction of the rotating disc 110 in fig. 8 is clockwise rotation, the stations corresponding to the actuator feeding device 200, the gas tank feeding device 300 and the assembly mechanism 400 can be sequentially arranged, or a plurality of stations can be left in the middle, and positions can be reserved for adding other processes in the future.

Specifically, the conveying table 100 further includes a baffle 130 disposed around the outside of the rotating disc 110, the baffle 130 is fixed to the working platform, the cross section of the accommodating groove 120 is U-shaped, and the opening of the U-shape faces the baffle 130. The shape of the baffle 130 limited by the accommodating groove 120 is adapted to the shape of the main body of the actuator 710, so as to limit the movement of the actuator 710 in the accommodating groove 120, where the baffle 130 is only in contact with the main body of the actuator 710, and the lower part of the baffle 130 is not in contact with the injection port 712 of the actuator 710, which may be achieved by providing a relief groove or the like. The position of the baffle 130 corresponding to the actuator feeding device 200 is provided with a notch 131 (see fig. 8 and 10), and the accommodating groove 120 can be aligned with the notch 131.

When the actuator 710 with the accommodating opening 711 facing upwards falls from the actuator feeding device 200 above, the injection opening 712 of the actuator 710 can fall into the accommodating groove 120 through the notch 131, and after the injection opening 712 falls to the bottom of the accommodating groove 120, the rotating disc 110 rotates, so that the baffle 130 and the accommodating groove 120 can enclose a shape matched with the body of the actuator 710, i.e. the actuator 710 is tightly pressed in the accommodating groove 120 to be fixed.

In this embodiment, the actuator loading device 200 and the gas tank loading device 300 determine the assembly efficiency, wherein the actuator loading device needs to be specially designed for the actuator or be retrofitted to existing equipment according to the specific structure of the actuator because the actuator is of an unconventional geometry. The actuator feeding device will be described in detail below.

As shown in fig. 3, the actuator feeding device 200 includes a first vibration feeding tray 210 and a feeding chute 220 for outputting actuators 710 in a preset arrangement posture, a feed inlet of the feeding chute 220 is in butt joint with an outlet of the first vibration feeding tray 210, and a discharge outlet of the feeding chute 220 is located above the conveying table 100 and enables the actuators 710 with the receiving openings 711 facing upwards to fall into the receiving groove 120 when the conveying table 100 moves the receiving groove 120 to below the discharge outlet.

Specifically, as shown in fig. 4, 5 and 6, the first vibration loading tray 210 includes a vibration chassis 8100, a hopper 8200 provided on the vibration chassis 8100, a spiral rail 8300 provided on a sidewall of the hopper 8200, and a plurality of screen structures provided along a conveying direction of the spiral rail 8300.

The vibration chassis 8100 is capable of vibrating at a specific frequency, the hopper 8200 is provided on and fixed to the vibration chassis 8100, and the hopper 8200 may vibrate with the vibration chassis 8100 when the vibration chassis 8100 vibrates. The carrier surface of the spiral rail 8300 on the side wall of the hopper 8200 forms an inclination angle with the horizontal plane direction, that is, the carrier surface of the spiral rail 8300 is an inclined plane, when the hopper 8200 vibrates, the spiral rail 8300 synchronously vibrates, so that the actuator continuously or discontinuously jumps along with the vibration, and a high-frequency inertia force is actually applied to the actuator, so that the actuator continuously or discontinuously slides on the inclined plane against the gravity, and the actuator continuously moves forwards along the conveying direction of the spiral rail 8300.

The screening structure is specially used for guaranteeing the gesture direction of the actuator during output and is mainly divided into a direction selecting mechanism and a direction orienting mechanism. The direction selecting mechanism can check the gesture direction of each actuator passing through the direction selecting mechanism, and the actuator meeting the gesture direction can continue to pass.

Because the gesture direction of the materials when crawling on the spiral track 8300 is random, a plurality of materials with unsatisfactory gesture directions are bound on the spiral track 8300, and the materials can be blocked by the direction selecting mechanism and can not pass through the direction selecting mechanism when passing through the direction selecting mechanism, but the materials are continuously moved upwards by the vibration driving force of the vibration chassis, and finally the materials can only fall from the spiral track 8300 and fall into the bottom of the hopper 8200 to restart crawling upwards along the spiral track 8300. Or the material which does not meet the requirements in the gesture direction falls into the bottom of the hopper 8200 from some specially designed leakage holes on the spiral track 8300, and only the material which meets the requirements in the gesture direction can finally reach the outlet of the material conveying groove through various direction selecting mechanisms.

The direction selecting mechanism is used for screening materials in various gesture directions, and when the materials in various gesture directions pass through the mechanism, the materials in the gesture directions meeting the requirements pass through and continuously ascend and advance along the spiral track.

One direction selecting mechanism can only select one or a few types from actuators in various gesture directions, and for actuators in different gestures, the actuators with gesture directions meeting the conditions can be finally selected by arranging a plurality of direction selecting mechanisms with different structures and orderly arranging the direction selecting mechanisms at various positions on the spiral track 8300.

The direction selecting mechanism passively screens the gesture direction of the actuator. Although satisfactory actuators are obtained by providing a plurality of direction selection mechanisms, the efficiency is too low.

In order to improve the working efficiency of the actuator feeding device and ensure that the actuator feeding device has enough discharging speed, it is desirable that as many workpieces as possible can reach the outlet of the actuator feeding device at one time in the moving process. In this embodiment, the plurality of screening structures, at least one of which is a directional mechanism.

The orientation mechanism can correct the posture of a part of the workpieces which do not accord with the required posture direction in the actuator (on the spiral track 8300), and the workpieces are automatically corrected into the correct posture from the incorrect posture by means of continuous advancing movement of the workpieces.

Compared with the direction selecting mechanism, the direction selecting mechanism automatically corrects the gesture of the workpiece, which is an active action and can improve the feeding efficiency of the vibration disc.

The plurality of screening structures can continuously send out the actuators at the discharge port at the end of the spiral track 8300 according to the specified gesture direction through correcting the gesture of the actuators by the orientation mechanism and screening the actuators with different gestures by one or more orientation selection mechanisms, and after entering the feeding slideway 220 to adjust the direction, the actuators are downwards output at one end of the injection port.

The number of the direction selecting mechanisms in the screening structure is not limited, and one, two, three and the like can be provided, so that the number and the specific structure of the direction selecting mechanisms can influence the output efficiency of the final actuator, but the number and the specific structure are not necessary, and can be flexibly selected according to the situation by a person skilled in the art.

In this embodiment, the orientation mechanism used in the screening structure includes hooks 8410 and a flip slot 8420. The hanging hook 8410 is hung above the spiral rail 8300, and the overturning groove 8420 is arranged on the spiral rail 8300 below the hanging hook 8410. The orientation mechanism can turn the actuator 8710 in a specific posture in the conveying direction by 180 ° to turn around.

The last material automatically output from the first vibration loading tray is an actuator 710 with the assembly end facing backward (i.e., opposite to the conveying direction). As can be seen from the figure, the mounting end of the L-shaped actuator 710 is provided with a receiving opening 711 for inserting the gas tank 720, and since the gas tank 720 is cylindrical, the receiving opening 711 can also be regarded as cylindrical, and the axial direction thereof is the opening direction. The actuator 710 has the largest length in the opening direction of the accommodating port 711, and the other end opposite to the mounting end of the actuator 710 is provided with an injection port 712 facing to one side (i.e., in the radial direction of the accommodating port 711), and since the injection port 712 is not rectangular in shape and the injection port 712 is facing to one side, the outer wall of the actuator 710 is an arcuate surface 8421, and thus the actuator 710 cannot stand on the spiral rail 8300 through the arcuate surface 8421, and it is possible that the actuator 710 stands on the spiral rail 8300 with a small probability that the accommodating port 711 faces downward. The actuator 710 is preferably in a lying position when conveyed on the spiral track 8300. The actuator 710 in the prone position can be easily removed from the upright actuator 710 by designing a corresponding direction selecting mechanism, for example, a transverse blocking strip 8610 is arranged on the spiral track 8300, and the height of the blocking strip 8610 is slightly higher than that of the actuator 710 in the prone position. One end of the barrier strip 8610 is connected to one side of the spiral rail 8300, and the other end extends along the conveying direction.

For convenience of description, the receiving port 711 of the actuator 710 is oriented in the longitudinal direction. Since the ejection port 712 of the actuator 710 is directed to one side in the radial direction, the ejection port 712 protrudes outside the diameter of the accommodation port 711 of the actuator 710, the radial direction coplanar with the direction of the ejection port 712 is set as the width direction in the actuator 710 in the lying posture, and the direction perpendicular to the length direction and the width direction of the actuator 710 is set as the height direction.

The length of the actuator 710 in the length direction, the width direction, and the height direction is L1, L2, and L3, respectively, L1 > L2 > L3, and the length L3 of the actuator 710 in the height direction is approximately equal to the outer diameter of the opening of the housing port 711.

Similarly, the actuator 710 having a length direction different from the conveying direction can be easily eliminated by providing the corresponding direction selecting mechanism on the spiral rail 8300. For example, a direction selecting notch 8620 (see fig. 3) is formed by setting a narrow point of a width of a certain position of the spiral track 8300, the specific width may be L2-L1, the direction selecting notch 8620 is located at one side of the spiral track 8300, and a shielding object is arranged at the opposite side of the spiral track 8300. When the actuator 710 having a length direction different from the conveying direction passes through the length of the track, the center of gravity is located outside the spiral track 8300 and is vibrated down.

The same vertical bars 8610 may be used to a similar effect. When the barrier 8610 is used, a space between the barrier 8610 and one of the side wall of the hopper 8200 and the spiral rail 8300 (i.e., a shutter) in a direction perpendicular to the conveying direction is provided to accommodate the material passing through in a preset posture.

The direction selecting mechanism (screen structure) of the above-described structure by designing the height limiting or eliminating (the actuator 710 having a length direction different from the conveying direction) is to make the actuator 710 (material) have a posture in which the receiving opening 711 (in the conveying direction) faces forward or backward when being conveyed to the reversing groove 8420, so that the operation effect of the direction selecting mechanism composed of the reversing groove 8420 and the hook 8410 is improved, but these two direction selecting mechanisms are not essential. Those skilled in the art can flexibly select the materials according to the situation.

The orientation mechanism (i.e., the screen structure) composed of the flipping groove 8420 and the hook 8410 is described in detail below.

When the material moves to the edge of the turning groove 8420 along the conveying direction, if the receiving opening 711 of the actuator 710 faces forward, the lifting hook 8410 can hook the front end (the edge of the receiving opening 711) of the material, while the front end of the material is hooked, the front end of the material is suspended and starts to enter the turning groove 8420, while the rear end of the material still continues to vibrate and moves forward on the spiral track 8300 until the rear end of the material also enters the turning groove 8420, and finally, the lifting hook 8410 briefly hooks the front end of the material while the rear end of the material hooked by the lifting hook 8410 slides into the turning groove 8420, at this time, the two are equivalent to hinging, and then the rear end of the material is in a rotating motion taking the lifting hook 8410 as a rotating center relative to the front end or swinging during the falling process of the rear end of the material directly due to gravity. When the rear end of the material falls to the lowest point, that is, the length direction of the actuator 8710 is almost in a state that the receiving port is upward, the hook 8410 is separated from the front end of the material, and the rear end of the material continues to advance due to inertia, and finally turns to face the conveying direction and falls onto the bottom surface of the turning groove 8420, completing the 180 ° turning in the conveying direction.

If the actuator 710 with the receiving opening 711 facing backward moves to the edge of the flipping groove 8420, the hook 8410 cannot block the movement of the actuator 710 because the forward end of the actuator 710 does not have any structure that can be engaged with the hook 8410, so that the actuator 710 in such a posture receives a movement inertia that the end with the injection opening 712 falls directly into the flipping groove 8420 and the flipping does not occur.

The distance between the bottom end of the hook 8410 and the bottom of the turnover groove 8420 is greater than the length of the material so that the material hooked by the hook 8410 is separated from the hook 8410 after being turned. The distance from the hook 8410 to the edge of the reversing groove 8420 in the conveying direction is smaller than that of the case L1 so that the hook 8410 can hook the edge of the receiving opening 711 of the actuator 710 (i.e., the front end of the material) before the actuator 710 whose receiving opening 711 is forward falls into the reversing groove 8420.

Specifically, a bracket 8430 is provided on one of the hopper 8200 and the spiral rail 8300 for suspending the hanging hook 8410, for example, a transverse bracket 8430 is provided on a side wall of the hopper 8200, one end of the bracket 8430 is fixed to the side wall of the hopper 8200, and the other end of the bracket 8430 horizontally extends above the spiral rail 8300 and is connected to the upper end of the hanging hook 8410; or a vertical bracket 8430 is arranged on one side of the spiral track 8300, a transverse rotating shaft is arranged above the bracket 8430, one end of the rotating shaft horizontally penetrates into the upper side of the spiral track 8300, and a lifting hook 8410 is hung on the rotating shaft.

The upper end of the hook 8410 is movably connected with the bracket 8430, the lower end of the hook 8410 is provided with a hook 8411, the hook 8411 faces away from the conveying direction, and the lower end of the hook 8410 can swing along the conveying direction. For example, the upper end of the hook 8410 may be formed in a multi-section chain-like structure, or may be formed in a flexible structure such as a rope, which is not limited thereto.

In this embodiment, a suspension rod 8431 is disposed between the hook 8410 and the bracket 8430, one end of the suspension rod 8431 is hinged to the bracket 8430, and the other end of the suspension rod 8431 is hinged to the upper end of the hook 8410.

Further, a counterweight 8412 is further disposed at the lower end of the hook 8410. In the conveying direction, the hook 8411 and the counterweight 8412 are respectively located at two sides of the hook 8410, so as to prevent the counterweight 8412 from affecting the action of the hook 8411 to hook the front end of the material. By arranging the balancing weight, after the front end of the material is separated from the hook 8411, the hook 8411 can quickly reach the previous position for the next material. If the hook 8410 is returned to the vicinity of the home position and is stabilized for too long, the next material may be missed. Therefore, by setting a reasonable weight and a connection position of the balancing weight, the lifting hook 8410 can be quickly restored to the vicinity of the original position.

Further, in the conveying direction, a side wall of the turnover slot 8420 is an arc surface 8421, an upper end of the arc surface 8421 extends upward to the spiral track 8300, and a lower end of the arc surface 8421 is smoothly connected with a bottom surface of the turnover slot 8420. The arcuate surface 8421 is used to guide the material to flip, for example, the diameter of the corresponding arc of the arcuate surface 8421 may be determined by the length of the actuator 710.

Further, a multi-stage spiral rail 8300 is provided on a side wall of the hopper 8200. In the conveying direction, the upper end of one side wall of the turning groove 8420 is connected with the tail end of one section of the spiral rail 8300, and the bottom of the turning groove 8420 is connected with the head end of the other section of the spiral rail 8300.

Further, the reversing groove 8420 is provided with blocking plates 8422 on both sides perpendicular to the conveying direction, and the distance between the two blocking plates 8422 can prevent the material from being horizontally deflected by 180 °, for example, the distance between the two blocking plates 8422 is set between L2 and L1, that is, greater than L2 and less than L1, excluding L2 and L1.

In this embodiment, the body of the actuator 710 is cylindrical. Since the body is a circumferential side surface on the side surface facing the ejection port 712 in the width direction, in the actuator 710 in the flat lying position, the contact surface is almost a line when the circumferential side surface contacts the spiral rail 8300, and the ejection port 712 of the actuator 710 is inevitably tilted to one side due to the gravity center instability. Therefore, in the actuator 710 in the lying posture, the ejection port 712 of the actuator 710 has three orientations, either to the left and right, or downward.

Further, the screening structure further includes an orientation mechanism for twisting the injection port 712 of the actuator 710 to a predetermined angle in the conveying direction, which is disposed after the reversing slot 8420, and which includes a guide bar 8510 disposed on the spiral rail 8300 located after the reversing slot 8420. In the conveying direction, one end of the guiding bar 8510 is connected to one side of the spiral rail 8300, the other end of the guiding bar 8510 extends spirally, and the guiding bar 8510 can guide the material to twist to the same posture during the moving process.

Further, in order to guide the actuator 710 in cooperation with the guide bar 8510 and complete the torsion jet 712 to a specific angle, the spiral rail 8300 of the guide bar 8510 is provided with a rail surface which is tiltable to one side in the width direction thereof. For example, the guide bar 8510 is disposed at the outer side (principle spiral center) of the spiral rail 8300, and the inner side of the spiral rail 8300 is inclined downward, i.e., the outer side is higher than the inner side in the width direction of the rail. At the same time, the blocking plate 8422 is provided at the inner side, and the lower end of the blocking plate 8422 is connected with the spiral rail 8300, and is properly twisted by a certain angle with the spiral and inclination of the spiral rail 8300 and the arrangement of the mating guide bar 8510.

Finally, the ejection opening 712 of the actuator 710 is twisted by the guide bar 8510 to a specific angle in the conveying direction, for example, to a horizontal plane.

The actuator 710 finally output from the first vibration feeding tray 210 is oriented in the same longitudinal direction as the conveying direction of the spiral rail, the accommodating opening 711 faces the direction opposite to the traveling direction, and the ejection openings 712 all face the supporting surface (horizontal surface) uniformly. The actuators 710 aligned according to the above-mentioned posture may then enter the feeding chute 220, and the sectional shape of the feeding chute 220 perpendicular to the traveling direction is adapted to the actuators 710, so that the feeding chute 220 can be ensured to be always in a preset posture in the traveling process, and the actuators 710 are adjusted to make the accommodating opening 711 fall into the accommodating groove 120 on the conveying table 100 in an upward posture through a curved and twisted traveling path. Thereby providing a basis and potential for automated assembly of aerosol products.

In order to ensure that no error occurs during the conveyance, a direction selecting mechanism that can exclude the actuator 710 with the housing port 711 facing forward may be provided on the spiral track after guiding the actuator and twisting the ejection port to a specific angle, which will not be described in detail.

The feed rail assembly includes a rail body 321 and a rail (not shown, typically made of a transparent material to allow viewing of the gas tank 720 therein), between which the rail body 321 and the rail form a delivery channel that matches the diameter of the gas tank 720. The conveying channel is in an inverted U shape, one end of the conveying channel is in butt joint with the output port of the bottle unscrambler 310, and the other end of the conveying channel is arranged above the moving path of the accommodating groove 120. The feeding push rod 330 is arranged at one end of the conveying channel and used for pushing the air tank 720 into the conveying channel, and an anti-falling structure capable of preventing the air tank 720 from falling down after the feeding push rod 330 is reset is arranged on the inner wall of the inlet end of the conveying channel. For example, with the elastic block, the elastic block is forced to deform when the gas tank 720 passes, and returns to block the gas tank 720 from falling back after the gas tank 720 passes completely, thereby acting like a check valve.

A gas flow sensor or a gas pressure sensor may be provided in the collection port. In addition, the aerosol collecting device is also provided with a vacuum generating device and an oil-water separating device, wherein the vacuum generating device is used for generating negative pressure suction force on the collecting port side of the aerosol collecting device and sucking away sprayed liquid medicine; the oil-water separation device is used for separating the mixture of the sucked liquid medicine and the gas, and storing the liquid medicine in the collecting container to prevent the gas from being discharged to pollute the environment.

To further increase the degree of automation of the assembly equipment to complete more process steps.
