The utility model provides an automatic output equipment of cotton swab in continuous type cotton swab wrapping bag, the operation object is continuous type's cotton swab wrapping bag (the attached drawing is not shown), independently the packing has a cotton swab in every cotton swab wrapping bag, and these cotton swab wrapping bags are continuous, the form of end to end one after the other, although every cotton swab wrapping bag and the inner space of other cotton swab wrapping bag do not communicate with each other, but the tail end of last cotton swab wrapping bag and the head end of next cotton swab wrapping bag are continuous, from this, constituted as the utility model discloses the continuous type cotton swab wrapping bag of operation object. And the utility model discloses a first-hand job task is for the cotton swab in this continuous type cotton swab wrapping bag can be one by one automatic forward, promptly, towards the direction output of taking the medical personnel's of cotton swab hand (or taking the mechanical equipment of cotton swab, if, arm, manipulator).

Specifically, the utility model discloses an equipment during operation of the cotton swab in the automatic output continuous type cotton swab wrapping bag:

before the first time the device is put into operation, the head end of the entire continuous cotton swab packaging bag is manually placed on the guide rail in the transport and separation module and is pulled further manually until it bypasses the front end of the guide rail and is redirected in the direction of the meshing gear train until it is inserted between the meshing gears in the meshing gear train clamped in the transport and separation module, which constitutes an initial state in which the device can be put into operation, in which the continuous cotton swab packaging bag generally comprises four parts, namely a first part clamped between the meshing gear train 120 and a second part located between the meshing gear train 120 and the front end of the guide rail 110, a third part located above the guide rail 110 and a fourth part extending or accumulating at the rear end of the guide rail 110, which is located after the first part in the overall direction of extension of the continuous cotton swab packaging bag (as will be understood by the person skilled in the art, if the continuous cotton swab packaging bag is relatively short, the overall length is in this initial state, i.e. there may be no fourth part).

An operator can control the driving module 600 to provide driving power to the meshing gear set 120 through the control module 500, for example, press the control power, and at this time, the driving module 600 provides driving power to the meshing gear set 120 to drive the meshing gear set 120 in the transmission separation module 100 to rotate under the control of the control module 500.

The arrangement position of the engaging gear set 120 is not limited as long as it can make the rear portion of the packing bag be conveyed forward along the upper surface of the guide rail without interfering with the forward output of the swab 800 when the engaging gear set 120 rotates, since the portion of the packing bag sandwiched between the engaging gears moves away from the guide rail 110. Generally, the meshing gear set 120 may be disposed above or obliquely above the guide rail 110 (as will be understood by those skilled in the art, in this case, the cutting module should not only cut the upper surface of the packing bag, but also preferably cut the lower surface of the packing bag to ensure that the swabs are smoothly output forward, rather than being drawn into the meshing gears along with the lower surface of the packing bag that is not cut, in the direction of the meshing gear set), or may be disposed below or obliquely below the guide rail 110 (in this case, the cutting module should not cut the lower surface of the packing bag, but also cut the upper surface of the packing bag, so as not to affect the forward output of the swabs). In the embodiment, the engaging gear set 120 is disposed below the guide rail 110, in the transferring and separating module 100, the engaging gear set 120 below the guide rail 110 rotates, at least two gears in the engaging relationship can clamp and drive a first portion of the continuous cotton swab package located between the gears to move downwards or obliquely downwards (see fig. 2, the continuous cotton swab package moves obliquely downwards along the arrow in the figure), because the cotton swab package is continuous, the movement of the first portion pulls the second, third and fourth portions of the continuous cotton swab package, wherein after the movement of the third portion above the guide rail 110 is pulled, the movement of the first portion above the guide rail 110 is forward along the guide rail 110, and during the forward movement, the cutting of the cutting module 200 above the guide rail 110 is performed, the package is cut one by one, and as the previous package is continuously pulled by the continuous rotation of the meshing gear set 120, the cut package is conveyed forward along the upper surface of the guide rail 110 to the front end of the guide rail 110, and is redirected toward the meshing gear set 120, so that the swab 800 (illustrated here as the swab in the first cut package) in the cut package is separated from the cut package at the front end of the guide rail where the head of the swab 800 (in the present invention, the head of each swab refers to the portion of the swab in a single package that is at the end facing forward, and not to the portion of the swab at the end where the cotton is wrapped), the swab 800 does not advance as the severed portion of the bag is redirected toward the intermeshing gear set 120, but rather can advance with the swab head continuing forward, i.e., presenting the result of the automatic forward output of the swab 800. In the case of the cotton swab automatically fed forward, one way of handling the cotton swab may be to take the cotton swab out in time before the center of gravity of the cotton swab reaches the front end of the guide rail, that is, before the cotton swab drops immediately after the cotton swab extends out of the front end of the guide rail for a long time.

With the continuous rotation of the meshing gear set 120, the cut-off packaging bag is clamped between the internal gears of the meshing gear set 120 and continuously moves away from the guide rail (can move until entering the medical waste container), so that the part of the rear part of the continuous cotton swab packaging bag, which is located on the upper surface of the guide rail 110, is driven to continuously move forward along the guide rail 110 (at this time, of course, for each single packaging bag which belongs to the fourth part of the continuous cotton swab packaging bag and extends or accumulates at the rear end of the guide rail in the initial state, the packaging bag which is relatively forward is naturally driven to the guide rail), the packaging bag is continuously cut off one by one when passing through the cutting module 200, at this time, the cotton swabs in the cut-off packaging bag can be continuously and automatically output forward, the cut-off packaging bag is continuously clamped between the internal gears of the meshing gear set 120, conditions are provided for the subsequent cutting-off packaging bags and automatically outputting another cotton swab forward, and finally, another cotton swab can be continuously and automatically output forward.

Therefore, the utility model provides an equipment of automatic output continuous type cotton swab in cotton swab wrapping bag can high-efficiently open the cotton swab packing, makes things convenient for medical personnel to take, has effectively solved the personnel fatigue that the swab large tracts of land exists in the collection process, has pointed the local mill brokenly, sample cross contamination problem.

As will be understood by those skilled in the art, since, as described above, the packaging bag has the first portion sandwiched between the meshing gear sets and the second portion located between the meshing gear sets and the front and rear ends of the guide rail and the third portion located above the guide rail and located behind the first portion in the overall extending direction of the packaging bag in the initial state of the apparatus of the present invention (before the first energization operation is performed), when the apparatus starts to operate for the first time, the third portion is cut, and each individual packaging bag included in the first portion and the second portion has no chance to be cut by the cutting module, the cotton swab in each individual packaging bag corresponding to the first portion and the second portion can be manually taken out before the initial state is set for the apparatus of the present invention; or each individual package of the first and second parts may be customized to have no swab inside, and the first part may be slip clamped into the meshing gear set.

In the case of suspended sampling, i.e., when there is no need to continue to take the swab, the operator can control the control module 500, for example, to turn off the control power supply, so that the drive module 600 no longer provides power to the meshing gear set 120, at which time the meshing gear set 120 no longer rotates, and the continuous swab package stops moving, stops in a state where a portion is sandwiched between the meshing gear set 120, a portion is located between the meshing gear set 120 and the front end of the guide rail 110, a portion is located above the guide rail 110, and possibly a portion extends/accumulates at the rear end of the guide rail 110 (obviously, the portion sandwiched between the meshing gear set and the package located between the meshing gear set and the front end of the guide rail are already cut), and if it is necessary to resume sampling, the control power supply can be turned on, and the meshing gear set 120 resumes rotating, and as the package located above the guide rail 110 is pulled forward along the guide rail and cut one by one, wherein the swab is automatically output forward.

Preferably, the meshing gear set 120 includes a drive wheel and a driven wheel in meshing relationship.

The utility model discloses an equipment has the function of time delay control so that just shut down behind the single cotton swab of output, namely, control module 500's control, can be at each cotton swab from being exported forward automatically to can supplying medical personnel to take, and can not follow a certain opportunity in the period that drops on the guide rail, make drive module 600 automatic shutdown operation, thereby meshing gear train 120 stall, continuous type wrapping bag stop motion, no longer continue automatic output next cotton swab forward, this function mainly helps the realization through sensor 310. The relative positional relationship between the sensor 310 and the guide rail 110 satisfies: the projection of the sensor 310 on the horizontal plane on which the device is located is in front of the projection of the front end of the guide rail 110, i.e. the sensor 310 need not necessarily be located directly in front of the front end of the guide rail 110, but may be located above or below the front, as long as it can sense that the projection of the head of the swab passes by itself. When the sensor 310 detects that the projection of the head of the automatically output swab passes through the sensor 310, the delay control of the control module 500 connected to the sensor 310 is triggered, and the delay time may be determined according to the speed at which the swab is automatically output, that is, the running speed of the continuous packaging bag, for example, if it is required to make the projection of the head of the swab stop going forward after 3 cm from the sensor, and the running speed of the continuous packaging bag is 1 cm/s, the delay time may be set to 3 s, and of course, the delay time cannot be too long, and if the cotton swab is too long, that is, the center of gravity of the cotton swab has already extended out of the front end of the guide rail 110, the cotton swab will fall off and is not convenient to take.

Preferably, the sensor 310 is further capable of triggering the control module 500 when detecting that the projection of the tail of the swab passes the sensor, so that the control module 500 controls the driving module 600 to automatically resume the driving operation.

When the cotton swab is taken away, the projection of the tail of the cotton swab generally passes through the sensor 310, the sensor 310 can trigger the control module 500 after detecting that the projection of the tail of the cotton swab passes through the sensor 310, so that the driving module 600 automatically restores driving operation, the meshing gear set 120 restores rotation, the continuous packaging bag is driven to continue moving, the part of the continuous packaging bag, which is located at the upper part of the guide rail 110, is cut when moving forwards along the guide rail 110 to pass below the cutting module, and the cotton swab is continuously and automatically output forwards.

Of course, the control module of the present invention may also have other different control strategies, i.e. in addition to the above-mentioned control based on the sensing signal of the sensor, instead of or in addition to the above-mentioned control, the control module of the present invention may also be controlled based on an external signal, for example, the control module 500 may receive an external signal sent from an external computer or an external PLC, and control the driving module 600 to start or stop working based on the external signal.

Preferably, with reference to fig. 2, the apparatus further includes a swab guiding nozzle 410 located right in front of the automatically output swab, the swab guiding nozzle 410 includes a swab guiding nozzle front end 411 and a swab guiding nozzle rear end 412, the swab guiding nozzle rear end 412 is in a horn shape, and a through slot for the swab to pass through is formed in the swab guiding nozzle front end 411.

In the automatic output in-process of cotton swab, the cotton swab begins to break away from the front end of guide rail 110 gradually from the head, and the rear portion of cotton swab still is located above the guide rail 110 this moment, and in order to prevent that the cotton swab from dropping owing to stretch out the partial overlength of guide rail 110 front end, the utility model discloses set up cotton swab direction mouth 410, leave guide rail 110 front end at the cotton swab head after, can stretch into and be located the cotton swab direction mouth 410 in this cotton swab dead ahead, effectively reduced the risk that the cotton swab dropped.

Preferably, with reference to fig. 2, the projection of the swab guide nozzle 410 on the horizontal plane on which the device is located, the projection distance between the swab guide nozzle 410 and the sensor 310 before the projection of the sensor 310, is set to be sufficient, and at the end of the delay, the tip of the automatically output swab can protrude beyond the tip 411 of the swab guide nozzle.

Thus, when the delay is finished, the head of the automatically output cotton swab extends out of the front end 411 of the cotton swab guide nozzle, so that the head can be exposed in front of the guide nozzle 410, medical staff/mechanical hands can hold the exposed part conveniently, and the cotton swab is pulled away for use.

Preferably, referring to fig. 2, 3 and 6-8, the guide rail 110 is provided with a first position-limiting sidewall 111 and a second position-limiting sidewall 112 on both sides of the upper surface thereof.

The part of continuous type wrapping bag that is located on guide rail 110 is on the upper surface that is located guide rail 110, and has the setting of first spacing lateral wall 111 and the spacing lateral wall 112 of second through this upper surface both sides, can play the part that is located on the guide rail to the continuous type wrapping bag and carry out the effect of leading, avoids its skew guide rail, the emergence of the condition that drops even from the guide rail, guarantees the utility model discloses a normal operating of the equipment of the cotton swab in the automatic output continuous type cotton swab wrapping bag.

Preferably, referring to fig. 2, 3, 6 and 7, the transfer and separation module 100 further includes a rotatable pouch guide shaft 130, the pouch guide shaft 130 being located at a front end of the guide rail 110, the pouch guide shaft 130 having a circular cross-section.

Since the cut portion of the continuous envelope is deflected by the front end of the guide rail as pulled by the front portion thereof until it enters the meshing gear train, the smooth operation of the aforementioned deflection is facilitated by the envelope guide shaft 130 having a circular cross-section at the front end of the guide rail.

Preferably, referring to fig. 1, 2, 4, 5, 7 and 8, the cutting module 200 includes a blade carrier 210, a force applying structure and a cutting blade 220, the cutting blade 220 being fixed relative to the blade carrier 210, the force applying structure continuously providing a downward force to the blade carrier 210.

In one embodiment, the tool holder 210 may include a pressing block 211, the pressing block 211 may be integrally formed with the holder body of the tool holder 210 to form an integral tool holder, or may be separately manufactured and fixed to the holder body of the tool holder to form an integral tool holder, and the pressing block 211 may firmly press the cutting blade against the side wall 212 of the holder body of the tool holder (for example, a screw hole may be formed in the pressing block, and a screw head may be tightly pressed against the pressing block by screwing a screw into the screw hole, so that the pressing block firmly presses the cutting blade against the side wall of the holder body of the tool holder), thereby achieving the relative fixation of the cutting blade 220 and the tool holder 210.

The force application structure is not limited in structural form, and can be an elastic belt, two end parts of the elastic belt are fixed on two special fixing structures arranged on the guide rail, and the main body part of the elastic belt presses the top of the tool rest; it is also possible for one end to be fixed to the guide rail and the other end to be held by two sets of tool holder tension springs 230 (see fig. 2) or the like on top of the tool holder, or for a pressure block or the like provided on top of the tool holder, as long as it is possible to provide a continuous downward force to the tool holder, so that the cutting block can maintain a predetermined distance from the upper surface of the guide rail, or can return to the predetermined distance after the distance between the cutting block and the upper surface of the guide rail changes.

It can be understood that, the distance between the knife point of the cutting blade 220 and the upper surface of the guide rail 110 is too large, and when the distance is too large, the knife point cannot touch the packaging bag, and the packaging bag cannot be cut to expose the cotton swab, so ideally, the distance between the knife point of the cutting blade 220 and the upper surface of the guide rail is preset, so that the knife point can touch and cut the packaging bag. However, since there are swabs in the packaging bag and the distribution of the swabs in the packaging bag is random, and may be in the center, or may be on the left, on the right, or inclined left and right, when the cutting blade cuts the packaging bag, the cut part may be just the part of the swab which is pushed up, or may be the part of the swab which is left or right and is not pushed up by the swab, the "preset distance" may ensure that the tip of the cutting blade is enough to cut the part of the packaging bag which is not pushed up by the swab, but if the tip of the cutting blade 220 is cut by the tip of a certain packaging bag, obviously, the cutting blade 220 is also pushed up by the swab, at this time, the distance between the tip of the cutting blade 220 and the upper surface of the guide rail 110 changes, and is not longer the preset distance, but is greater than the preset distance, after the packaging bag is cut and is transported forward, the swab in the packaging bag is no longer pushed up by the cutting blade 220, and the blade holder 210 is driven to sink by the cutter holder 210, and the cutter holder 210 sinks down to a state where the distance between the cutter holder 220 is appropriate. The preset interval may preferably be 0.4mm to 0.6mm.

Further, the tool holder 210 may further include a positioning guide block 213, and the radian of the surface of the positioning guide block 213 in contact with the cutting blade 220 matches with the radian of the edge side of the cutting blade 220, for example, the edge side of the cutting blade 220 is an oblique edge, so the surface of the positioning guide block 213 in contact with the cutting blade 220 is also set to be an oblique surface, and the oblique direction and the oblique angle of the oblique surface are both consistent with the oblique edge, so that the cutting blade can be conveniently and quickly positioned in a manner that the edge side of the cutting blade 220 completely contacts the corresponding surface of the positioning guide block 213, and then the cutting blade 220 and the pressing block 211 of the tool holder are fixed to each other.
