Referring to fig. 1, a mask producing apparatus 100 is provided in a first embodiment of the present application. The mask producing apparatus 100 includes a control device, a fabric supply device (not shown), and a table 110. The mask producing apparatus 100 further includes a nose bridge strip supplying device (not shown), a pressure welding device (not shown), a character spraying device (not shown), an ear band processing device 120, an image collecting device 130, a folding device 140, a die cutting device 150, and a sorting device 160, which are sequentially arranged along the production line direction of the mask production.

Specifically, referring to fig. 2, the fabric supply device is used for supplying the mask fabric 11. The nose bridge strip supplying device is used for supplying the nose bridge strip. The bonding device is used for bonding the multi-layer mask cloth 11 together. The character spraying device is used for spraying identification characters on the mask cloth 11. The ear band processing device 120 is used for processing the ear band on each corresponding mask blank on the mask cloth 11. The folding device 140 is used for folding the mask cloth 11 in half. The die cutting device 150 is used for cutting each corresponding mask semi-finished product on the folded mask cloth 11 into corresponding mask finished products 13. The specific structures of the fabric supply device, the nose bridge strip supply device, the pressure welding device, the character spraying device, the ear band processing device 120, the folding device 140 and the die cutting device 150 are the prior art, and are not described herein again.

As will be understood by those skilled in the art, after the mask cloth 11 passes through the ear band processing device 120, a plurality of mask blanks are sequentially arranged on the mask cloth 11 along the direction of the mask production line. When each mask semi-finished product passes through the die cutting device 150, the die cutting device 150 cuts the mask semi-finished product into corresponding mask finished products 13. Each mask semi-finished product corresponds to one mask finished product 13.

The image collecting device 130 is disposed between the ear band processing device 120 and the folding device 140, and is used for collecting mask image data of each corresponding mask blank on the mask cloth 11.

Specifically, the image capture device 130 may employ an industrial camera. As shown in fig. 2, in the present embodiment, the image capturing device 130 is mounted on the table 110 by a fixing bracket 131. The image pickup device 130 is located above the mask cloth 11 so as to be able to photograph the corresponding mask image data of each mask blank downward.

Since the image capturing device 130 is disposed between the ear band processing device 120 and the folding device 140, when the image capturing device 130 captures the mask image data, the corresponding mask semi-finished product is located between the ear band processing device 120 and the folding device 140. It can be understood that the corresponding mask blank is not folded but is in an extended state of being laid horizontally when it is located between the ear band processing device 120 and the folding device 140, so that a complete image of the surface of one mask blank can be captured by the image capturing device 130 every time it is captured.

Referring again to fig. 3, a sorting device 160 is provided downstream of the die cutting device 150. The control device is used for judging whether the semi-finished mask product corresponding to the mask image data is qualified according to the comparison result of the mask image data and the preset mask image standard, and is used for controlling the sorting device 160 to sort the semi-finished mask product 13 corresponding to the semi-finished mask product according to the judgment result.

Specifically, the control device may be a controller, a microprocessor, a single chip microcomputer, or the like. The control device is electrically connected with the image acquisition device 130 and is used for receiving the mask image data acquired by the image acquisition device 130. The mask image standard can be preset in the control device. In actual production, a plurality of standard sample masks can be selected, and the standard parameters of the mask image can be determined according to the average value of the parameters of the plurality of standard sample masks. The standard parameters of the mask image can be the size of the ear belt, the posture and the position of a welding point of the ear belt, the posture and the position of a nose bridge strip and the like.

It can be understood that the mask image data acquired by the image acquisition device 130 is actual mask image data of the corresponding mask semi-finished product, and therefore, when the mask image data conforms to the preset mask image standard, the mask semi-finished product corresponding to the mask image data conforms to the production requirement and is a qualified mask semi-finished product; and when the mask image data does not accord with the preset mask image standard, the mask semi-finished product corresponding to the mask image data does not accord with the production requirement and is an unqualified mask semi-finished product.

Along the production line direction of the mask production, after each mask semi-finished product on the mask cloth 11 passes through the image acquisition device 130, the mask semi-finished product sequentially passes through the folding device 140 and the die cutting device 150. After being cut by the die-cutting device 150, each mask blank is cut into a corresponding mask finished product 13. It can be understood that the qualified semi-finished mask product is cut by the die cutting device 150 to become the qualified finished mask product 13. The unqualified mask semi-finished product is cut by the die cutting device 150 to form the unqualified mask finished product 13.

The sorting device 160 is disposed downstream of the die-cutting device 150, so that after the finished mask products 13 are discharged from the die-cutting device 150, the control device can control the sorting device 160 to sort the finished mask products 13 which have just been discharged.

Specifically, as described above, the control device can determine whether the mask semi-finished product corresponding to each mask image data is qualified according to the comparison result between the mask image data and the preset mask image standard. Therefore, when the mask finished product 13 corresponding to the unqualified mask semi-finished product is discharged from the die cutting device 150, the control device can control the sorting device 160 to sort the mask finished product 13 into the unqualified mask finished product 13; when the mask finished product 13 corresponding to the qualified mask semi-finished product is discharged from the die cutting device 150, the control device can control the sorting device 160 to sort the mask finished product 13 into the qualified mask finished product 13.

In one embodiment, the control device records an NG signal when judging that a mask semi-finished product corresponding to certain mask image data is unqualified; and when the control device judges that the mask semi-finished product corresponding to certain mask image data is qualified, recording an OK signal. It can be understood that when the control device records NG signals of a certain unqualified mask semi-finished product, a preset number of mask semi-finished products are arranged between the unqualified mask semi-finished product and the discharging position of the die cutting device 150 at intervals, and therefore the control device can count after the NG signals are recorded.

It will be appreciated that the control means counts the same period as the production period for a single mask. Every time the control device counts one number, one finished mask 13 is discharged from the die cutting device 150. Therefore, when the number counted by the control device is equal to the predetermined number, all mask semi-finished products of the predetermined number are discharged from the die cutting device 150 to be the mask finished products 13, and the next discharged mask semi-finished product is the mask finished product 13 corresponding to the unqualified mask semi-finished product, at this time, the control device controls the sorting device 160 to perform the operation of sorting the unqualified mask finished products 13, so that the sorting device 160 can accurately sort the mask finished products 13 corresponding to the unqualified mask semi-finished products to be the unqualified mask finished products 13.

Of course, the control device may count the NG signal by a counter, and the control device may similarly control the operation of the sorting device 160 based on the number of counts of the counter after recording the NG signal.

Similarly, the control device counts the recorded OK signals of a certain qualified mask semi-finished product. When the counted number is the predetermined number, the next discharge is the mask finished product 13 corresponding to the qualified mask semi-finished product, and at this time, the control device controls the sorting device 160 to perform the operation of sorting the qualified mask finished product 13, so that the sorting device 160 can accurately sort the mask finished product 13 corresponding to the qualified mask semi-finished product into the qualified mask finished product 13.

In other embodiments, if the control device records NG or OK signal for a certain mask semi-finished product and then the mask semi-finished product reaches the discharging position of the die-cutting device 150 after a predetermined time, the control device can control the sorting device 160 to perform the operation of sorting the unqualified or qualified mask finished products 13 after the predetermined time, and then the sorting device 160 can also sort the mask finished products 13 corresponding to the mask semi-finished product.

The mask producing apparatus 100 includes an image capturing device 130, a sorting device 160, and a control device. The image collecting device 130 is disposed between the ear band processing device and the folding device 140, and is used for collecting mask image data of each corresponding mask blank on the mask cloth 11. The control device is used for judging whether the semi-finished mask product corresponding to the mask image data is qualified or not according to the comparison result of the mask image data and the preset mask image standard. When the mask finished product 13 corresponding to the mask semi-finished product is discharged from the die cutting device 150, the control device can control the sorting device 160 to act according to the judgment result of whether the mask semi-finished product is qualified or not, so that the sorting device 160 sorts the mask finished product 13 corresponding to the mask semi-finished product. The whole sorting process is fully automatic, manual operation is not needed, time and labor are saved, the risk of secondary pollution can be reduced, and the quality control consistency rate is high.

Referring to fig. 3, in an embodiment, the mask producing apparatus 100 further includes: good product collection device 171 and scrap collection device 172. The sorting device 160 is used for sorting the qualified mask finished products 13 into the good product collecting device 171, and sorting the unqualified mask finished products 13 into the waste collecting device 172. The good product collecting device 171 is used for collecting the qualified mask finished products 13. The waste collecting device 172 is used for collecting the unqualified mask finished products 13.

Specifically, the good product collecting device 171 may be a collecting box capable of directly collecting the mask finished products 13, or may be a conveying mechanism for conveying the mask finished products 13 to a collecting area. As shown in fig. 3, in the present embodiment, the good product collecting device 171 is a conveyor belt, and the conveyor belt is disposed on the table 110. The conveyer belt is used for conveying qualified mask finished products 13 to a good product collecting area for packing.

In this embodiment, the waste collecting device 172 may be a collecting box capable of directly collecting the mask finished products 13, or may be a conveying mechanism for conveying the mask finished products 13 to a waste collecting area. As shown in fig. 3, in the present embodiment, the waste collecting device 172 is a waste tank, and the waste tank is disposed on the worktable 110 and inclined downward, so that the unqualified mask finished product 13 enters the waste tank and falls down along the waste tank, and is collected to the lower part of the waste tank.

Referring to fig. 3, in an embodiment, the sorting apparatus 160 includes: a first catch member 161 and a drive member 162. First seizing point 161 has a first position and a second position, the first position being closer to the outfeed position of die cutting apparatus 150 than the second position. In the first position, the control device can control the first obtaining member 161 to obtain the mask finished product 13 discharged from the die-cutting device 150. In the second position, the control means can control first shutter 161 to release finished mask 13. The actuator 162 is controlled by the control device. The driving member 162 is used for driving the first catching member 161 to switch between the first position and the second position.

Specifically, in the present embodiment, first capture member 161 may be a jaw, suction cup, hook, or the like. The driving member 162 may be a cylinder or a linear motor, etc. The actuator 162 may be mounted to the table 110 by a mounting bracket. In the following description, the first capturing member 161 is used as a clamping jaw and the driving member 162 is used as an air cylinder. The sorting device 160 and the image capturing device 130 may share a control device, or may be respectively provided with a control device.

When the mask finished product 13 is discharged from the die cutting device 150, the control device controls the cylinder to drive the clamping jaw to move to the first position, so that the clamping jaw is close to the discharging position of the die cutting device 150, and at the moment, the control device controls the clamping jaw to clamp the mask finished product 13 discharged from the die cutting device 150. After the clamping jaws clamp the mask finished product 13, the control device controls the cylinder to drive the clamping jaws to move to the second position, so that the mask finished product 13 is driven to move to the second position and is released.

In this embodiment, the second position corresponds to the waste collection device 172, and when the first catch 161 is in the second position, the waste collection device 172 (i.e., the waste chute) is located below the first catch 161. Therefore, if the mask finished product 13 is an unqualified mask finished product 13, the mask finished product 13 can fall into the waste collection device 172 after being released at the second position, and thus can be accurately sorted into an unqualified mask finished product 13.

It will be appreciated that the waste collector 172 may not be provided under the first capturing member 161, and the mask finished product 13 may be released at the second position and then dropped to the ground directly, and may be sorted into defective mask finished products 13.

Referring to fig. 3, in an embodiment, the sorting apparatus 160 further includes: and a second catch 163. The second catch 163 has a third position and a fourth position. The third position is closer to the second position than the fourth position. In the third position, the control means can control the second shutter 163 to shutter the finished mask 13 released by the first shutter 161 in the second position. In the fourth position, the control means can control the second shutter 163 to release the mask finished product 13. The driving member 162 can drive the second catch member 163 to switch between the third position and the fourth position.

Specifically, in this embodiment, the second capturing member 163 may be a jaw, a suction cup, a hook, or the like. The first capturing member 161 and the second capturing member 163 may share one driving member 162, or may be provided with one driving member 162.

If the mask finished product obtained by the first obtaining member 161 is a qualified mask finished product 13, the control device controls the first obtaining member 161 to move from the first position to the second position, and controls the second obtaining member 163 to move to the third position. And the control means controls the first obtaining member 161 to release the mask finished product 13 at the second position, and controls the second obtaining member 163 to obtain the mask finished product 13. Then, the second capturing member 163 is controlled to move the mask product 13 to the fourth position.

In the present embodiment, the fourth position corresponds to the good product collecting device 171, and when the second obtaining member 163 is at the fourth position, the good product collecting device 171 (i.e. the conveyor belt) is located below the second obtaining member 163. Therefore, if the mask finished product 13 is a qualified mask finished product 13, the mask finished product 13 can fall into the good product collecting device 171 after being released by the second obtaining member 163 at the fourth position, and thus can be accurately sorted into the qualified mask finished product 13.

It is understood that in other embodiments, the second position may correspond to the good product collecting device 171, and when the first obtaining member 161 is in the second position, the good product collecting device 171 is located below the first obtaining member 161. The first obtaining member 161 can obtain the qualified mask finished product 13, and then release the qualified mask finished product to the good product collecting device 171 at the second position. Similarly, the fourth position may correspond to the waste collection device 172, and when the second catcher 163 is in the fourth position, the waste collection device 172 is located below the second catcher 163. Therefore, if the first acquirer 161 acquires a defective mask finished product 13, the mask finished product 13 can fall into the garbage collector 172 after being released by the second acquirer 163 at the fourth position, and can be accurately sorted into a defective mask finished product 13.

Referring to fig. 2, in an embodiment, the mask producing apparatus 100 further includes a backlight source 133, and the image capturing device 130 and the backlight source 133 are respectively located on different sides of the mask cloth 11 in the thickness direction.

Specifically, as shown in fig. 2, the backlight 133 is located below the mask cloth 11, and the light emitted therefrom is irradiated upward on the mask blank. The irradiation of the backlight 133 is beneficial for the image acquisition device 130 to obtain a clear and easily-distinguished mask image.

Referring to fig. 2, in an embodiment, the mask producing apparatus 100 further includes a baffle 134 located between the image capturing device 130 and the mask cloth 11, the baffle 134 is provided with a first opening 101, and the image capturing device 130 is capable of capturing mask image data through the first opening 101.

Specifically, as shown in fig. 2, in the present embodiment, the baffle 134 is located below the image capturing device 130, so as to block external natural light and reduce the influence of the natural light on the image. Meanwhile, since the first opening 101 is damaged by the baffle 134, the image capturing device 130 can still capture mask image data through the first opening 101.

Referring to fig. 2, in an embodiment, the mask producing apparatus 100 further includes an air blowing device 135. When the image capturing device 130 captures the mask image data, the air blowing device 135 is used to expand the ear band of the mask semi-finished product corresponding to the mask image data by blowing air.

Specifically, in the production line of the mask, the ear band processed on the mask cloth may curl or may droop on the surface of the mask cloth. The ear band can be unfolded by blowing air to the surface of the cloth of the mask or blowing air to the ear band through the air blowing device 135, so that when the image acquisition device 130 acquires the image data of the mask, the acquired image data of the mask is smooth, and the size of the ear band can be accurately judged according to the image data of the mask.

The blowing device 135 may be disposed upstream of the image capturing device 130 and near the image capturing device 130, so as to ensure that the ear band of the mask semi-finished product is unfolded when the image capturing device 130 captures the mask image data.

The specific structure of the blowing device 135 can be implemented by the prior art, and will not be described in detail herein.

Referring to fig. 4, in an embodiment, the mask producing apparatus 100 further includes: a photosensor 181 and a triggering device. The control device is used for controlling the image acquisition device 130 to acquire mask image data according to the trigger signal, wherein the period for triggering the photoelectric sensor 181 by the trigger device is the same as the production period of a single mask.

Specifically, the photosensor 181 and the triggering device may be provided on the table 110. In the present embodiment, the trigger device includes a code wheel 182. The outer peripheral surface of the code wheel 182 is provided with a notch 102 recessed in the radial direction. The code wheel 182 is rotatable relative to the photosensor 181. When the code wheel 182 is rotated, the outer peripheral surface of the code wheel 182 is positioned in the opening 103 of the photosensor 181, so that the opening 103 of the photosensor 181 can be blocked. Until the notch 102 of the code wheel 182 rotates to the opening 103 of the photoelectric sensor 181, the notch 102 can expose the opening 103 of the photoelectric sensor 181, so that the signal of the photoelectric sensor 181 jumps, and a trigger signal is generated.

It can be understood that the triggering device triggers the photoelectric sensor 181 at a period, that is, a period in which the photoelectric sensor 181 generates a triggering signal, that is, a period in which the image capture device 130 captures image data of the mask. Because the photoelectric sensor 181 produces the cycle of the trigger signal, that is, the cycle of the image acquisition device 130 acquiring the mask image data, it can be ensured that each mask semi-finished product is acquired with the mask image when passing through the image acquisition device 130, and the consistency of the image acquisition position of each mask can be ensured.

When the photoelectric sensor 181 generates a trigger signal, the image acquisition device 130 acquires an image, and when the photoelectric sensor 181 is not triggered, the image acquisition device 130 does not acquire an image, so that the burden of image acquisition can be reduced.

Further, in the foregoing embodiment, the control device needs to perform counting. It will be appreciated that the control means may count on the basis of the trigger signal generated by the photo sensor 181, the control means counting each time the photo sensor 181 generates a trigger signal. Since the period of the trigger signal generated by the photoelectric sensor 181 is the same as the production period of a single mask, the control device counts once and discharges a mask finished product 13, which meets the counting requirement in the foregoing embodiment.

In one embodiment, the die cutting device 150 includes a cutter wheel (not shown) for cutting the mask cloth into mask products and a driving shaft (not shown) for driving the cutter wheel to rotate. The code wheel 182 may be coaxially connected to the driving shaft so that the code wheel 182 may be driven by the driving shaft and thus the rotation period of the code wheel 182 may automatically correspond to the production period of the mask.

In other embodiments, the code wheel 182 may be coaxially connected to other transmission shafts of the mask producing apparatus 100, and a driving motor for driving the code wheel 182 to rotate may be separately provided.

Referring to FIG. 4, in another embodiment, two spaced notches 102 are provided uniformly along the circumference of the code wheel 182. Specifically, in the present embodiment, the code wheel 182 rotation period is twice the production period of a single mask. When the code wheel 182 rotates for a half turn, one notch 102 can expose the opening 103 of the photoelectric sensor 181, the photoelectric sensor 181 generates signal jump, when the code wheel 182 continues to rotate for a half turn, the other notch 102 can expose the opening 103 of the photoelectric sensor 181, and the photoelectric sensor 181 generates signal jump again.

The second embodiment of the present application also provides a mask producing apparatus (not shown). The mask production apparatus of the second embodiment has substantially the same basic structure as the mask production apparatus of the first embodiment, and details thereof are omitted here. The following description focuses on differences between the mask producing apparatus of the present embodiment and the mask producing apparatus 100 of the first embodiment.

In the second embodiment, the third position is closer to the outfeed position of the die cutting apparatus than the fourth position. In the third position, controlling means can control the second and acquire the piece and directly acquire the gauze mask finished product of follow the cutting device ejection of compact. In the fourth position, the control device can control the second acquisition part to release the finished mask.

The second acquisition part can acquire qualified finished products of the masks and can also acquire unqualified finished products of the masks. For example, the first acquisition part may acquire and release qualified finished masks, and the second acquisition part may acquire and release unqualified finished masks, that is, the first acquisition part may be used to sort qualified finished masks, and the second acquisition part may be used to sort unqualified finished masks. Also can make first acquisition and acquire and release unqualified gauze mask finished product, the second acquires and releases qualified gauze mask finished product, and first acquisition is used for sorting unqualified gauze mask finished product promptly, and the second acquires the piece and is used for sorting qualified gauze mask finished product.

The second embodiment is different from the first embodiment in that the second obtaining member does not need to indirectly obtain the mask finished product released from the first obtaining member, but directly obtains the mask finished product discharged from the die cutting device.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
