Description

Technical Field

[0001] The invention belongs to the technical field of stringing equipment, and in particular relates to a labeling and feeding device and an automatic stringing machine. Background Art

[0002] As people's living standards improve, their requirements for special diets are getting higher and higher, and more and more special catering stores have been put into operation. Among them, the market share of skewers hotpot restaurants has grown most significantly. Most traditional skewers hotpot restaurants prepare various types of ingredients for customers. Customers only need to put the required food into the hotpot and cook it. Restaurants that adopt this type of service are very popular with customers.

[0003] However, most traditional skewers hotpot restaurants have staff manually making the skewers of ingredients. On the one hand, manual production is unhygienic and can easily affect the quality of the ingredients. On the other hand, manual production is slow, and the structure of the formed skewers of ingredients is poorly stable and easy to fall off, which reduces production efficiency.

[0004] In order to improve production efficiency, people have developed automatic skewering machines to realize automatic food skewering. The automatic skewering machine in the prior art includes a loading mechanism, a conveying mechanism and a unloading mechanism. The loading mechanism is used to convey the skewer rod into the conveying mechanism, the conveying mechanism conveys the skewer rod into the unloading mechanism, and the unloading mechanism inserts the tip of the skewer rod into the preset food and unloads the formed skewers of food to a preset position.

[0005] In the prior art, most feeding mechanisms use a roller structure with grooves on the surface to clamp the labels, and a sensor unit is provided at the output end of the roller structure. The sensor unit cooperates with a control system to control the roller structure to feed the labels one by one to the conveying mechanism. In the actual production process, in view of the certain limitations of the sensing sensitivity of the sensor unit, when using the feeding mechanism to feed the labels, only slow feeding can be used. Otherwise, when the feeding speed is too fast, the sensitivity of the sensor unit will not match the preset feeding speed, which may easily lead to missed or repeated signing, affecting production efficiency and being detrimental to enterprise development.

[0040] In one embodiment of the present invention, Figures 1 to 5As shown, a label dispensing and feeding device is provided, which is suitable for an automatic stringing machine, including a label linear conveying mechanism 10, a label dispensing output mechanism 20 and a differential transmission mechanism 30; the label linear conveying mechanism 10 includes a linear conveying component 11 and a plurality of groups of limiting fixtures 12 arranged at the output end of the linear conveying component 11, the limiting fixture 12 is provided with a first limiting groove 13 for loading a single label, and the output end of the first limiting groove 13 is adapted to the input end of the corresponding stringing mechanism of the automatic stringing machine; the label dispensing and output mechanism 20 includes a label dispensing wheel 21 and a hopper 22, the hopper 22 is arranged at the input end of the linear conveying component 11 and is used to stack and store the labels, the label dispensing wheel 21 is rotatably connected to the output end of the hopper 22, a plurality of groups of second limiting grooves 23 for loading a single label are evenly distributed on the label dispensing wheel 21, and the label dispensing wheel 21 is used to stack the labels The labels in the hopper 22 are transported one by one to the corresponding first limiting grooves 13; the differential transmission mechanism 30 includes a synchronous transmission component 31, a first sprocket 32, a second sprocket 33 and a chain, the input end of the synchronous transmission component 31 is connected to the output end of the linear conveying component 11, the first sprocket 32 ​​is tightly connected to the output end of the synchronous transmission component 31, the second sprocket 33 is tightly connected to the driving shaft of the label separation wheel 21, and the two ends of the chain are respectively engaged with the first sprocket 32 ​​and the second sprocket 33; wherein, a label drop position is provided between the output end of the label separation wheel 21 and the linear conveying component 11, and the time interval between two adjacent first limiting grooves 13 passing through the label drop position as the corresponding limiting fixture 12 moves is equal to the time interval between two adjacent second limiting grooves 23 passing through the label drop position as the label separation wheel 21 rotates.

[0041] Specifically, the working principle of the label separation and feeding device is as follows: the labels are conveyed into the hopper 22, and the linear conveying component 11 drives the limiting fixture 12 to pass through the label drop position in sequence. At the same time, the linear conveying component 11 drives the first sprocket 32 ​​to rotate through the synchronous transmission component 31, so that the second sprocket 33 drives the label separation wheel 21 to rotate, so that the labels accumulated in the hopper 22 smoothly enter the second limiting groove 23, and reach the label drop position as the label separation wheel 21 rotates, and then enters the first limiting groove 13; compared with the feeding mechanism of the automatic stringing machine in the prior art, which adopts a sensor unit to cooperate with the control system to control the loading of labels one by one, and cannot realize high-speed loading, which affects the production speed, the label separation and feeding device provided in the embodiment of the present invention adopts a differential sprocket structure, and realizes orderly and high-speed loading of single labels through mechanical cooperation. It has a simple structure and significant effect. At the same time, the equipment manufacturing cost is low, it has higher practicality and market prospects, and is conducive to enterprise development.

[0042] like Figures 1 to 5As shown, in another embodiment of the present invention, there is a tooth ratio between the first sprocket 32 ​​and the second sprocket 33 for adjusting the rotational speed ratio of the first sprocket 32 ​​and the second sprocket 33, and there is a number ratio between the first limit groove 13 and the second limit groove 23 for adapting the tooth ratio; specifically, when the tooth ratio of the first sprocket 32 ​​and the second sprocket 33 is fixed, the number ratio of the first limit groove 13 and the second limit groove 23 is adjusted, so that the first limit groove 13 and the second limit groove 23 can move at the same speed; when the number ratio of the first limit groove 13 and the second limit groove 23 is fixed, the tooth ratio of the first sprocket 32 ​​and the second sprocket 33 is adjusted to obtain an adapted transmission ratio, so that the first limit groove 13 and the second limit groove 23 can move at the same speed.

[0043] like Figures 1 to 5As shown, in another embodiment of the present invention, the linear conveying component 11 is a sprocket conveyor, and the interval length between two adjacent first limiting grooves 13 is an integer multiple of the width of a tooth groove on the driving chain of the linear conveying component 11. Preferably, the interval length between two adjacent first limiting grooves 13 is an even multiple of the width of a tooth groove on the driving chain of the linear conveying component 11 to facilitate rapid adjustment of the transmission ratio and improve assembly efficiency. For example, in this embodiment, two groups of the first limiting grooves 13 are respectively formed on each of the limiting fixtures 12, and the interval length of adjacent first limiting grooves 13 is 31.75 mm. The tooth groove width of the driving sprocket of the linear conveying assembly 11 is 15.875mm; the number of teeth of the driving sprocket of the linear conveying assembly 11 is equal to the number of teeth of the second sprocket 33, the number of the second limiting grooves 23 is equal to the number of teeth of the second sprocket 33, the number of teeth of the second sprocket 33 is twice the number of teeth of the first sprocket 32, and the sprocket drive spindle of the linear conveying assembly 11 is drivingly connected to the input end of the synchronous transmission assembly 31; in this embodiment, the number of teeth of the driving sprocket of the linear conveying assembly 11 is thirty-two, the number of teeth of the first sprocket 32 ​​is sixteen, and the number of teeth of the second sprocket 33 is thirty-two. The second limiting grooves 23 are evenly distributed on the labeling wheel 21. Specifically, the driving sprocket rotates synchronously with the first sprocket 32 ​​at the same angular velocity through the synchronous transmission component 31. Since the number of teeth of the second sprocket 33 is twice the number of teeth of the first sprocket 32, the second sprocket 33 and the first sprocket 32 ​​are both meshed with the chain and rotate at the same linear velocity. Therefore, the angular velocity of the first sprocket 32 ​​is twice that of the second sprocket 33, that is, when the linear conveying component 11 drives the limiting fixture 12 to move the length of two teeth (one tooth groove), the second sprocket 33 drives the labeling wheel 21 to rotate the length of one tooth (one tooth groove), thereby making the first The limiting groove 13 and the second limiting groove 23 can correspond one to one, ensuring that a single label is stably transferred from the first limiting groove 13 to the preset second limiting groove 23. The use of this structure for the label loading process is conducive to high-speed loading, greatly improving production efficiency, while ensuring loading accuracy, which is beneficial to enterprise development; technicians in this field should understand that the number of teeth of the first sprocket, the number of teeth of the second sprocket, and the number of the first limiting groove and the second limiting groove in this embodiment are only one of the feasible solutions. In the remaining embodiments, the technical solution of using a suitable tooth ratio and slot ratio to adapt to achieve the same technical effect should be included in the protection scope of the present invention.

[0044] like Figures 1 to 5As shown, in another embodiment of the present invention, the labeling output mechanism 20 further includes a mounting frame 24, a labeling drive shaft 25, a material shifting assembly 26 and a material discharging assembly 27. The mounting frame 24 is arranged at the input end of the linear conveying assembly 11, and the hopper 22 is installed in the mounting frame 24. The labeling drive shaft 25 is rotatably connected to the mounting frame 24 and is located at the output end of the hopper 22. The labeling rotating wheel 21 is tightly connected to the labeling drive shaft 25, and the second sprocket 33 is tightly connected to the labeling drive shaft 25. At the end of the driving shaft 25, the material shifting assembly 26 is arranged in the hopper 22 and is used to shift the labels accumulated in the hopper 22 to increase the interval between adjacent labels. The material discharging assembly 27 is arranged in the hopper 22 and is used to discharge the excess labels in the second limiting groove 23. Specifically, a plurality of functional mechanism components are used to effectively ensure that the labels accumulated in the hopper 22 can enter the corresponding first limiting groove 13 one by one. The structure is simple and the effect is significant, which is conducive to improving the practicality of the label output mechanism 20 and is conducive to the development of the enterprise.

[0045] like Figures 1 to 5 As shown, in another embodiment of the present invention, the material-digging assembly 26 includes a material-digging drive shaft 261, a material-digging block 262, a driven gear 263 and a driving gear 264. The material-digging drive shaft 261 is rotatably connected to the output end of the hopper 22, the material-digging block 262 is tightly connected to the material-digging drive shaft 261, the driven gear 263 is tightly connected to the end of the material-digging drive shaft 261, the driving gear 264 is tightly connected to the labeling drive shaft 25, the driving gear 264 is meshed with the driven gear 263, and the material-digging block 262 is square.

The number of the material-shifting blocks 262 is two groups, and the two groups of the material-shifting blocks are arranged at intervals. The corner positions of the material-shifting blocks 262 can extend into the hopper 22 to abut against the labels when they rotate; when the material-shifting assembly 26 is working, the driving gear 264 rotates to drive the driven gear 263 to rotate, so that the material-shifting drive shaft 261 drives the material-shifting block 262 to rotate, so that the ends of the material-shifting block 262 alternately abut against the labels accumulated in the hopper 22, thereby realizing the shifting effect, effectively increasing the distance between adjacent labels, and improving the feeding efficiency.

[0046] like Figures 1 to 5 As shown, in another embodiment of the present invention, the radius length of the driving gear 264 is much larger than that of the driven gear 263. The use of a differential gear structure is beneficial to increasing the rotational angular velocity of the material-dispensing drive shaft 261 per unit time, thereby increasing the number of times the end of the material-dispensing block 262 abuts against the label, thereby further improving the material-dispensing efficiency.

[0047] In another embodiment of the present invention, the discharge assembly 27 includes a discharge roller 271 and a rubber ring 272 arranged on the circumferential edge of the discharge roller 271. The discharge roller 271 is tightly connected to the output end of the synchronous transmission assembly 31 and is located above the labeling wheel 21. The bottom of the rubber ring 272 is in contact with the labeling wheel 21. The rubber ring 272 is made of silicone material, which is beneficial to increase the friction between the rubber ring 272 and the label, thereby improving the discharge effect.

[0048] like Figures 1 to 5 As shown, in another embodiment of the present invention, a baffle 241 for adjusting the orientation of the label is provided on the mounting frame 24, and the number of the baffles 241 is two groups. The two groups of baffles 241 are symmetrically arranged on the opposite inner walls of the mounting frame 24 and located at the output end of the hopper 22. The cross-section of the baffle 241 is arranged in an arc-shaped structure. The use of the baffle 241 structure is conducive to adjusting the orientation of the label so that the length direction of the label is parallel to the length direction of the second limiting groove 23, thereby preventing the label from being displaced and affecting the loading.

[0049] In another embodiment of the present invention, a limiting seat 242 for limiting the loading in the second limiting groove 23 is provided in the mounting frame 24, and the limiting seat 242 is provided with a limiting arc groove, and the limiting arc groove is concentrically arranged with the label separation gear. The bottom wall of the limiting arc groove can be fitted with the outer side wall of the tooth portion of the label separation gear that rotates into the limiting arc groove, so that a limiting cavity for limiting the label strip is formed between the second limiting groove 23 and the limiting seat 242.

The label separation feeding device provided in the embodiment of the present invention adopts a differential sprocket structure, which realizes the orderly and high-speed loading of a single label through mechanical coordination. It has a simple structure and significant effect. At the same time, the equipment has low manufacturing cost, higher practicality and market prospects, and is conducive to enterprise development.
