Description

Technical Field

[0001] The utility model relates to a stick conveying device with a waste rejection function. Background Art

[0002] In the production process of swabs, for example, cotton swabs (including swabs, cotton swabs are used as an example in the present invention) need to be transported with small sticks (swab sticks) and the ends (one end or both ends) of the small sticks are wrapped with cotton. If there is no cotton at the end of the small stick or the shape, amount, fullness or cleanliness of the cotton does not meet the requirements, then the cotton swab is a defective product. During the transportation of cotton swabs, the small sticks on the chain are arranged in a continuous state. The existence of defective products leads to waste in subsequent operations (such as packaging). For example, a defective product in a packaging bag will also affect the quality of the entire product of this package. The appearance of defective products in the production process of various swabs such as cotton swabs (including swabs, etc.) affects the quality of subsequent products. Removing defective products will cause the swabs transported on the chain to be discontinuous, and subsequent continuous operation cannot be performed.

[0003] For this purpose, in the swab conveying device with a waste rejection structure in Chinese patent document CN219448379U, finished products (such as cotton swabs, etc.) are arranged on the first conveying chain and conveyed, and pass through the finished product detection mechanism, and are detected by the finished product detection mechanism; if the finished product is detected as a qualified product, it will continue to be conveyed by the first conveying chain and pass through the waste rejection mechanism without being rejected; if the finished product is detected as an unqualified product (i.e., a defective product), it will continue to be conveyed by the first conveying chain and be rejected when passing through the waste rejection mechanism, and the defective product will be rejected from the first conveying chain, and the defective product will be separated from the first conveying chain to achieve waste rejection, and the rejection will create an empty space on the first conveying chain where no finished product (such as cotton swabs) is placed; regardless of whether it is rejected or not, the first conveying chain will continue to run to the first conveying toothed disc for connection and conveying, and each time the first conveying chain conveys a unit (such as a cotton swab or an empty space without a cotton swab) forward, the first conveying toothed disc will also rotate to convey a unit (such as a cotton swab or an empty space without a cotton swab) Transfer; because the first conveyor chain generates empty space for conveying due to waste rejection, when the connection conveying is transferred to the first conveyor sprocket, the first conveyor sprocket also performs empty space conveying at the corresponding position; during the rotation and conveying process of the first conveyor sprocket, the first conveyor sprocket normally conveys the finished products, and the second conveyor sprocket rotates to cooperate and normally receive the finished products; if there is an empty space for conveying on the first conveyor sprocket, the second conveyor sprocket stops rotating (the second conveyor chain also stops running), and waits for the first conveyor sprocket to rotate to convey the empty space (generated due to waste rejection) and convey the finished products normally, and then the second conveyor sprocket continues to rotate to cooperate and connect to receive the finished product conveying (the second conveyor chain also continues to run), and the second conveyor sprocket undertakes the conveying of finished products without being affected by the empty space, and the second conveyor sprocket conveys the finished products (such as cotton swabs, etc.) to the second conveyor chain, and the second conveyor sprocket and the second conveyor chain are not affected by the empty space, and the finished products on the second conveyor sprocket and the second conveyor chain are evenly and equidistantly spaced, and can be continuously output for subsequent continuous operation. It can not only realize waste rejection and remove defective products on the first conveyor chain; but also when the second conveyor gear disc cooperates with and connects to take over the first conveyor gear disc, it can eliminate the vacancies caused by waste rejection, avoid discontinuous vacancies in the conveyance of finished products, and realize continuous conveyance and output of finished products after waste rejection, so as to facilitate subsequent continuous operations (such as taking away packaging).

[0004] However, in the swab conveying device with a waste rejection structure, the first conveying chain that runs non-stop cannot stably and accurately reject only unqualified cotton swabs (defective products) during the process of conveying cotton swabs that are continuously and closely arranged. For example, if an unqualified product appears among the continuously qualified cotton swabs, other qualified cotton swabs on the front and / or rear sides of the cotton swab to be rejected will also be rejected, which is very likely to cause mis-rejection. Not only does it result in relatively large vacancies, but the waiting time of the second conveying toothed disc to stop running is also relatively increased, affecting production efficiency. In addition, rejecting qualified cotton swabs as unqualified products will also lead to an increase in the scrap rate (increasing unnecessary swab losses) and increased costs. Utility Model Content

[0005] In view of the technical problems existing in the background technology, the utility model aims to provide a skewer conveying device with a waste rejection function, which has a more reasonable waste rejection position, is relatively more accurate in waste rejection, and reduces unnecessary skewer losses.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme: a stick conveying device with a waste rejection function includes a first conveying mechanism and a second conveying mechanism, the first conveying mechanism includes a first conveying chain and a first conveying toothed disc, the first conveying chain is connected to the first conveying toothed disc for feeding, the first conveying toothed disc is also provided with a first conveying guide plate, the second conveying mechanism includes a second conveying chain and a second conveying toothed disc, the second conveying toothed disc is connected to the second conveying chain for feeding, the second conveying toothed disc is also provided with a second conveying guide plate, the first conveying toothed disc is connected to the second conveying toothed disc for feeding, a waste rejection station is provided on the top of the first conveying toothed disc, a waste rejection mechanism is arranged at the waste rejection station, a waste discharge port is provided on the first conveying guide plate, the waste discharge port divides the first conveying guide plate into a front guide plate and a rear guide plate, the waste discharge port is arranged between the front guide plate and the rear guide plate, the waste discharge port is located above the first conveying toothed disc, and the waste discharge port is arranged corresponding to the waste rejection mechanism.

[0007] The following various optimizations or supplementary explanations can be made on the above technical solutions respectively.

[0008] For example, the waste discharge port is arranged in a trumpet-shaped manner, the waste discharge port is arranged to be larger at the top and smaller at the bottom, and the waste discharge port is located directly above the top highest point of the first conveying toothed disc.

[0009] For another example, the first conveying toothed disc is drivingly connected to the first transmission shaft, the first transmission shaft is also drivingly connected to the first gear, the first conveying chain is drivingly connected to the first gear, and the radius of the first conveying toothed disc is greater than the radius of the first gear.

[0010] For example, the first conveying sprocket and the second conveying sprocket respectively adopt circular turntables with feeding concave teeth distributed on the circumferential edge, the rotation axes of the first conveying sprocket and the second conveying sprocket are arranged horizontally and parallel, and the feeding concave teeth are evenly distributed on the circular turntable; the first conveying chain and the second conveying chain are respectively provided with supporting blocks, and the supporting blocks are provided with material accommodating recesses, and the material accommodating recesses are evenly arranged on the supporting blocks.

[0011] Among them, the first conveying chain and the first conveying toothed disc are arranged for synchronous feeding, and the second conveying toothed disc and the second conveying chain are arranged for synchronous feeding.

[0012] For example, the first conveying toothed disc is connected to the first conveying chain by transmission, the second conveying toothed disc is connected to the second conveying chain by transmission, the first conveying toothed disc is arranged at the output end of the first conveying chain, the second conveying toothed disc is arranged at the input end of the second conveying chain, the first conveying toothed disc is connected to the first transmission mechanism by transmission, and the second conveying toothed disc is connected to the second transmission mechanism by transmission. The first transmission mechanism and the second transmission mechanism share a driving motor and the second transmission mechanism is equipped with a transmission clutch device, or the first transmission mechanism and the second transmission mechanism are respectively equipped with their own driving motors.

[0013] In addition, a detection sensor for detecting whether there are finished products on the second conveying toothed disc is provided before the second conveying toothed disc and after the waste rejection mechanism. The detection sensor is used to cooperate with the control of the intermittent transmission pause of the second transmission mechanism, and the detection sensor is connected to the second transmission mechanism.

[0014] In addition, a finished product detection mechanism is provided on the upper or lower side of the first conveying chain. The finished product detection mechanism is located before the waste rejection mechanism. The waste rejection mechanism includes a waste rejection implementation component. The waste rejection implementation component is also equipped with a waste rejection power source. The finished product detection mechanism is connected to the waste rejection power source. The finished product detection mechanism is used to cooperate with the control of the waste rejection power source to operate the waste rejection.

[0015] For example, the finished product inspection mechanism includes an inspection camera, a waste rejection power source is connected to a waste rejection implementation component, and the finished product inspection mechanism is connected to the waste rejection power source. The waste rejection implementation component adopts a rotary waste rejection component, and the waste rejection power source drives the rotary waste rejection component to rotate and reject waste; the waste rejection power source adopts a waste rejection motor or a waste rejection cylinder, and the rotary waste rejection component adopts a rotary waste rejection rod.

[0016] The beneficial effect of the utility model is that in the swab conveying device with waste rejection function, it is found that there are many problems in directly rejecting waste on the first conveying chain, so optimization and improvement are carried out, and the waste rejection station and the corresponding waste rejection mechanism are arranged at the top position of the first conveying toothed disc, and a waste discharge port is arranged on the first conveying guide plate, which will not affect the coordinated conveying of the first conveying toothed disc and the first conveying guide plate, and can also discharge waste smoothly. At the same time, the cotton swabs on the first conveying toothed disc are relatively large in distance from each other, so it is not easy to mis-reject during waste rejection, and it is not easy to affect other cotton swabs before and after the target cotton swab that needs to be rejected. Waste rejection is relatively accurate, reducing or even avoiding the mistaken rejection of qualified and normal swabs along with defective products, and reducing the loss of unnecessary (qualified) swabs. Compared with directly rejecting waste on the first conveying chain, its waste rejection position is more reasonable, waste rejection is relatively more accurate, and unnecessary swab loss is reduced.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the implementation of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the embodiments of the utility model are within the scope of protection of the utility model.

[0024] Referring to the drawings, in an example of this embodiment, the stick conveying device with a reject rejection function includes a first conveying mechanism 38 and a second conveying mechanism 44 .

[0025] The first conveying mechanism 38 includes a first conveying chain 39 (not fully shown in the figure) and a first conveying toothed disc 42. The first conveying chain 39 is connected with the first conveying toothed disc 42 for feeding. The first conveying chain 39 conveys the swabs (such as cotton swabs, etc.) to the first conveying toothed disc 42. The first conveying toothed disc 42 is also equipped with a first conveying guide plate 43. The second conveying mechanism 44 includes a second conveying chain 45 and a second conveying toothed disc 46. The second conveying toothed disc 46 is connected with the second conveying chain 45 for feeding. The second conveying chain 4 5 The swabs (such as cotton swabs, etc.) are transported to the second transport toothed disc 46, which is also equipped with a second transport guide plate 47; the first transport guide plate 43 has an arc-shaped guide surface disposed on (protected on) the outer circumference of the first transport toothed disc 42, and cooperates with the transport transfer of the swabs, and the second transport guide plate 47 has an arc-shaped guide surface disposed on (protected on) the outer circumference of the second transport toothed disc 46, and cooperates with the transport transfer of the swabs, so that the first transport toothed disc 42 and the second transport toothed disc 46 are connected in feeding, and the cotton swabs are connected and transported. This is a mature technology and will not be repeated.

[0026] In order to relatively improve the accuracy of waste rejection, avoid the phenomenon of false rejection, reduce or even avoid the erroneous rejection of qualified and normal swabs along with defective products, and reduce the loss of unnecessary swabs, in the utility model, a waste rejection station 89 is provided on the top of the first conveying toothed disc 42, and a waste rejection mechanism 96 is arranged at the waste rejection station 89, which can directly reject the cotton swabs transported to the top position by the first conveying toothed disc 42 at the waste rejection station 89; and, when the first conveying guide plate 43 cooperates with the guide conveying cotton swabs above the first conveying toothed disc 42, a waste discharge port 50 will also be provided on the first conveying guide plate 43, wherein the waste discharge port 50 divides the first conveying guide plate 43 into a front guide plate 51 and a rear guide plate 52, and the waste discharge port 50 is arranged between the front guide plate 51 and the rear guide plate 52, and the waste discharge port 50 is located above the first conveying toothed disc 42. The waste discharge port 50 is arranged corresponding to the waste rejection mechanism 96. The first conveying guide plate 43 with the waste discharge port 50 can also cooperate with the waste rejection work. The waste discharge port 50 is provided for the waste rejection mechanism 96 to discharge the cotton swab when rejecting the waste, so that the cotton swab can be smoothly discharged from the waste discharge port 50 (such as flying out), so that the waste rejection mechanism 96 of the waste rejection station 89 at the top of the first conveying toothed disc 42 can smoothly reject the cotton swab transported to the top position on the first conveying toothed disc 42.

[0027] Among them, the first conveying chain 39 and the first conveying toothed disc 42 convey cotton swabs with the same efficiency, that is, the conveying amount of cotton swabs (including the corresponding waste rejection positions) is consistent within the same time, and the cotton swabs on the first conveying toothed disc 42 are relatively spaced apart from each other, and it is not easy to make mistaken rejection during waste rejection. The waste rejection is relatively accurate, which reduces or even avoids the mistaken rejection of qualified and normal swabs along with defective products, thereby reducing the loss of unnecessary swabs. The curvature of the top of the first conveying toothed disc 42 can even be used to form high and low positions to further reduce the occurrence of mistaken rejection.

[0028] In the swab conveying device with waste rejection function, the waste rejection station 89 and the corresponding waste rejection mechanism 96 are arranged at the top position of the first conveying toothed disc 42, and the waste discharge port 50 is arranged on the first conveying guide plate 43. Not only will it not affect the coordinated conveying of the first conveying toothed disc 42 and the first conveying guide plate 43, but it can also smoothly discharge waste. At the same time, the cotton swabs on the first conveying toothed disc 42 are relatively spaced apart from each other, so it is not easy to mis-reject during waste rejection, and it is not easy to affect other cotton swabs before and after the target cotton swab that needs to be rejected. Waste rejection is relatively accurate, reducing or even avoiding the mistaken rejection of qualified and normal swabs along with defective products, and reducing the loss of unnecessary (qualified) swabs. Compared with directly rejecting on the first conveying chain 39, its waste rejection position is more reasonable, and waste rejection is relatively more accurate, reducing the loss of unnecessary swabs.

[0029] The following optimization or further explanation may be performed based on the above embodiments.

[0030] For example, the waste discharge port 50 is arranged in a bell-shaped shape, and the waste discharge port 50 is arranged to be larger at the top and smaller at the bottom, ensuring that the cotton swabs and the like can be smoothly discharged from the waste discharge port 50 after being separated from the first conveying toothed disc 42, and the waste discharge port 50 arranged in a bell-shaped shape allows the cotton swabs and the like to be discharged smoothly, avoiding waste discharge difficulties; and the waste discharge port 50 is located directly above the top high point of the first conveying toothed disc 42, and is not easy to affect the first conveying guide plate 43. The first conveying guide plate 43 can smoothly and normally guide the materials and cooperate with the first conveying toothed disc 42 to convey the cotton swabs.

[0031] For example, the first conveying toothed disc 42 is transmission-connected to the first transmission shaft 86, and the first transmission shaft 86 is also transmission-connected to the first gear 53. The first conveying chain 39 is transmission-connected to the first gear 53. The radius of the first conveying toothed disc 42 is greater than the radius of the first gear 53. The first transmission shaft 86 drives the first conveying toothed disc 42 and the first gear 53 to rotate synchronously. The first gear 53 drives the first conveying chain 39 to run. The spacing between the cotton swabs on the first conveying toothed disc 42 is larger than the spacing between the cotton swabs on the first conveying chain 39, which facilitates smooth and accurate waste removal.

[0032] For example, the first conveying toothed disc 42 and the second conveying toothed disc 46 are respectively circular turntables with feeding concave teeth 95 distributed on the circumferential edge, the rotation axes of the first conveying toothed disc 42 and the second conveying toothed disc 46 are arranged horizontally and parallel, and the feeding concave teeth 95 are evenly distributed on the circular turntable. The first conveying chain 39 and the second conveying chain 45 are respectively provided with supporting blocks 90, and the supporting blocks 90 are provided with material receiving recesses 91, and the material receiving recesses 91 are evenly arranged on the supporting blocks 90. The feeding concave teeth 95 and the material receiving recesses 91 are provided for accommodating a single cotton swab, and a gap will be formed after being removed. This is a mature technology and will not be described in detail.

[0033] The first conveying chain 39 is synchronously fed with the first conveying toothed disc 42. For example, when the first conveying chain 39 conveys one unit (such as a cotton swab or an empty space without a cotton swab) forward, the first conveying toothed disc 42 will also rotate accordingly to convey one unit (such as a cotton swab or an empty space without a cotton swab) for transfer. The second conveying toothed disc 46 is synchronously fed with the second conveying chain 45. For example, when the second conveying toothed disc 46 rotates to convey one unit (such as a cotton swab or an empty space without a cotton swab) for transfer, the second conveying chain 45 will also convey one unit (such as a cotton swab or an empty space without a cotton swab) forward accordingly.

[0034] For example, the first conveying toothed disc 42 is connected to the first conveying chain 39 by transmission, the second conveying toothed disc 46 is connected to the second conveying chain 45 by transmission, the first conveying toothed disc 42 is arranged at the output end of the first conveying chain 39, the second conveying toothed disc 46 is arranged at the input end of the second conveying chain 45, the first conveying toothed disc 42 is connected to the first transmission mechanism 49 by transmission, and the second conveying toothed disc 46 is connected to the second transmission mechanism 87 by transmission. The first conveying toothed disc 42 is driven to rotate by the first transmission mechanism 49, and the second conveying toothed disc 46 is driven to rotate by the second transmission mechanism 87 by transmission. The first transmission mechanism 49 and the second transmission mechanism 87 share a driving motor and the second transmission mechanism 87 is equipped with a transmission clutch device. The transmission is disconnected and connected through the transmission clutch device. When the transmission is connected, the driving motor drives the first conveying toothed disc 42 and the second conveying toothed disc 46 to rotate together. When the transmission is disconnected, the second conveying toothed disc 46 pauses (stops rotating); or, the first transmission mechanism 49 and the second transmission mechanism 87 are respectively equipped with their own driving motors, and the second conveying toothed disc 46 can start and stop rotating during the continuous rotation of the first conveying toothed disc 42. The first conveying toothed disc 42 and the second conveying toothed disc 46 are rotated and connected to cooperate in conveying finished products (such as cotton swabs and other swabs), and the second conveying toothed disc 46 can also be stopped (stopped rotating) to wait for the first conveying toothed disc 42 to rotate and complete the empty space. The second conveying toothed disc 46 can match the feeding rhythm of the first conveying toothed disc 42. During operation, the second conveying toothed disc 46 can pause and wait so that after the empty space on the first conveying toothed disc 42 due to waste removal is completed, the second conveying toothed disc 46 continues to rotate and convey for feeding connection and cooperation. This is a mature technology and will not be described in detail.

[0035] Defective products are removed on the first conveying toothed disc 42; and when the second conveying toothed disc 46 cooperates with and connects to take over the first conveying toothed disc 42, the vacancies caused by the removal of waste products can be eliminated, thereby avoiding the situation where discontinuous vacancies occur in the conveyance of finished products, and achieving continuous conveyance and output of finished products after the removal of waste products, so as to facilitate subsequent continuous operations (such as taking away the packaging).

[0036] A detection sensor 94 (such as a photoelectric eye sensor, etc.) is provided before the second conveying toothed disc 46 and after the waste rejection mechanism 96 to detect whether the finished product exists on the second conveying toothed disc 46. The detection sensor 94 is used to cooperate with the control of the second transmission mechanism 87 to stop the transmission, and the detection sensor 94 is connected to the second transmission mechanism 87. The detection sensor 94 can transmit a signal to the second transmission mechanism 87 (such as a corresponding drive motor or transmission clutch, etc.) to cooperate with the control of the transmission, and can be connected through a controller (such as a PLC) or a computer, etc. When the detection sensor 94 detects that there is no finished product (i.e., an empty space), a signal can be fed back to the second transmission mechanism 87, so that the second transmission mechanism 87 stops driving the second conveying toothed disc 46 to rotate according to the detected empty space, and cooperates with the first conveying toothed disc 42 to rotate to complete the empty space (the empty space is eliminated), and then the second conveying toothed disc 46 is driven by the second transmission mechanism 87 to continue to rotate and cooperate to receive the finished product on the first conveying toothed disc 42. This is a mature technology and will not be repeated.

[0037] The upper or lower side of the first conveying chain 39 is provided with a finished product detection mechanism 48, which is located before the waste rejection mechanism 96. The finished product detection mechanism 48 detects the finished products on the first conveying chain 39 to determine whether the finished products are qualified. The waste rejection mechanism 96 includes a waste rejection implementation component 99, which is also provided with a waste rejection power source 93, and the waste rejection power source 93 drives the waste rejection implementation component 99 to operate and cooperate with the waste rejection operation.

[0038] The finished product detection mechanism 48 is connected to the waste rejection power source 93, and the finished product detection mechanism 48 is used to cooperate with the control of the waste rejection power source 93 to perform waste rejection. The waste rejection power source 93 performs waste rejection according to the detection signal of the finished product detection mechanism 48. If waste rejection is required, the waste rejection operation is performed, and if waste rejection is not required, the waste rejection operation is not performed. The finished product detection mechanism 48 transmits the signal to the waste rejection power source 93 to cooperate with the waste rejection, and can be connected through a controller (such as a PLC) or a computer. The finished product detection mechanism 48 includes a detection camera, and the waste rejection power source 93 is transmission-connected to the waste rejection implementation component 99. The finished product detection mechanism 48 is associated with the waste rejection power source 93 and is connected to cooperate with the control of the waste rejection power source 93 to perform waste rejection. For example, the waste rejection implementation component 99 adopts a rotary waste rejection component, which is set on the waste rejection shaft 97, and the waste rejection power source 93 drives the rotary waste rejection component to rotate and reject waste; for example, the waste rejection power source 93 adopts a waste rejection motor or a waste rejection cylinder, and the waste rejection power source 93 in the figure is a motor. The rotary waste rejection component uses a rotary waste rejection rod to match the waste rejection of a unit of cotton swabs. The waste rejection implementation component 99 can be set at the inner side of the first conveying toothed disc 42, and act on one end of the cotton swab on the inner side during waste rejection to pick up the cotton swab and reject it. The second conveying guide plate 47 and the first conveying guide plate 43 can be set separately or connected as a whole; in addition, their relative positions can be adjusted to be adjusted to a suitable position to cooperate with the guide conveying cotton swabs. The waste rejection position in the device can also be covered with a cover to collect the cotton swabs rejected.
