Description

Technical Field

[0001] The invention belongs to the technical field of non-standard packaging equipment, and specifically discloses a food continuous wrapping equipment controlled by stroke linkage. Background Art

[0002] Small block foods are usually individually packaged, and large-scale transportation is usually not in bulk but in the form of boxes and cartons. Therefore, there are many kinds of cartoning equipment for this demand. Based on the variety of types and specifications of small block foods, this type of equipment is non-standard equipment, and designers need to carry out targeted mechanism design according to the needs of specific users to meet the needs of actual production. In particular, in the application of the present invention, small block foods usually refer to small-dose chicken essence blocks packaged in small boxes. This type of food generally has a relatively smooth small packaging box, which is convenient for bulk storage and access. In considering the existing cartoning and wrapping equipment for the same food, the applicant found that most of the known equipment has some room for optimization in terms of coordinating the continuity of actions such as food stacking and carton packaging.

[0003] For example, the food stacking and feeding structure has a material transfer structure, which may favor one over the other in terms of maintaining the neatness of the stack and quickly transferring the well-stacked stack. Either the stacking is neat but the transfer efficiency is low, or the transfer efficiency is high but the stack may need an additional sorting structure to adjust the uneven state of the stack before it is put into the box, and the rationality of the mechanical structure is lacking. For example, between the folding structure of the paper box and the structure for putting food into the box, multiple connecting mechanical structures may need to be set to ensure the smoothness of the action execution, etc. Therefore, it is of practical significance for the applicant to design a new type of continuous wrapping equipment for small block foods in order to meet the needs of quickly wrapping food to improve production efficiency.

DETAILED DESCRIPTION

[0027] The implementation modes of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation modes of the present invention are not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0028] Combination Figures 1 to 3 As shown, a food continuous wrapping device controlled by stroke linkage includes a frame 1 provided with a feeding conveyor 2 and a discharging conveyor 3 which are parallel to each other, the feeding conveyor 2 and the discharging conveyor 3 are respectively arranged on both sides of the frame 1, and the frame 1 is also connected with an operating table 4, and a material pushing part, a material grabbing part, a material transferring part and a material boxing part are sequentially arranged between the feeding conveyor 2 and the discharging conveyor 3 along the material transfer sequence, wherein the material boxing part is composed of a carton board material rack 27, an electric push plate, a lifting boxing position, a stabilizing pressure rod 5 and a crank suction cup arm connected between the carton board material rack and the electric push plate, the feeding conveyor 2 transfers unwrapped food to the material pushing part, and the material boxing part pushes the boxed and wrapped food to the discharging conveyor, and is delivered by the discharging conveyor 3.

[0029] Based on the above main technical features, the implementation process of the present invention can be understood in the following order according to the feeding and discharging direction; feeding (until the accumulation reaches the upper limit of pushing) → pushing → stacking → transferring → pushing → boxing → discharging, wherein when pushing the material, the actions of taking the box board → pushing the box board → pressing → boxing are also performed simultaneously. Combined with the above technical features, the specific implementation process of the present invention is that the materials of small pieces of food for boxing are scattered along the feeding conveyor 2 to the material pushing part and accumulated to the quantity of a column of materials required for boxing. The material pushing part pushes it to the material grabbing part at one time and repeats the above process until the quantity of a layer of materials in the boxing requirement is met. The material grabbing part grabs all the materials of a layer to the material transfer part for stacking and repeats the above process until the total quantity of boxing is met. The materials of a box of stacked and stacked materials are about to be transferred to the material boxing part. The crank suction cup arm is carried out as the aforementioned material stacking and stacking is carried out. The flattened carton boards stacked on the carton board material rack 27 are gradually sucked out from the bottom and transferred to the electric push plate, which pushes the carton boards to the lifting and boxing position to wait for material boxing and packaging. At this time, the stacked materials are pushed to the top of the carton boards in place by the material transfer unit. As the stabilizing pressure bar 5 and the lifting and boxing position are synchronously lowered, the carton boards are folded and bonded with the front and rear ears of the complete folding edges in the lifting and boxing position as the stabilizing pressure bar 5 is lowered, and finally the materials are wrapped and boxed, and then the small food boxes after boxing are pushed to the discharging conveyor 3 by the electric push plate, and sent out by the discharging conveyor 3 for subsequent boxing.

[0030] In the above process, the execution devices of any two adjacent workstations are compactly arranged in space, and the transfer of materials between the various execution parts does not require too much time, which also reduces the demand for the travel arrangement of the execution parts. Basically, the travel required by each driven mechanical execution part will not be too long, which helps to improve the operation efficiency of the mechanical equipment. Especially in the field of boxing and wrapping of small block foods that the present invention is aimed at, the compact execution structure also reduces the probability of errors and reduces the workload of manual supervision. Each boxing of materials can be completed in a relatively consistent operation. Therefore, for technical personnel in this field, this equipment that does not require too much complexity and has almost no redundant actions is very suitable for executing production tasks for a long time without consuming too much production and maintenance costs.

[0031] Furthermore, in the present invention, any mechanical structure capable of executing an action is an essential component. The power source that drives its action is not mentioned in the present invention. Based on the linear action or circular action executed by it, it can be understood that it is driven by an electrically driven cylinder, a linear motor or a rotary motor. In order to achieve the accuracy of the machine's execution of actions, in addition to the sensors specifically mentioned in the present invention, the remaining actuators can selectively be provided with sensors to assist the machine in executing more precise actions. The type of sensor is generally infrared sensor. The technical purpose accomplished is presence perception. Based on the presence perception, it further determines whether the quantity meets the requirements, whether the material is in place and other basic packaging process requirements, and converts them into trigger conditions for the execution of the corresponding mechanical structure. Finally, the electric control system and the necessary electrical structures required for the electric control provided in the operating table 4 complete the operation of each mechanical execution structure. For the above-mentioned technical features not described, technicians in this field can selectively assemble and implement them according to their own existing technical conditions in combination with non-standard equipment with similar or same purposes.

[0032] Combination Figures 1 to 6 As shown, as a further technical solution of the present invention, the material grabbing part is composed of a vertical frame 6 standing above the frame 1, a translation slide rail connected to one side of the vertical frame 6, and a grabbing suction cup arm 7 mounted on the translation slide rail and capable of performing horizontal reciprocating motion along the translation slide rail. A plurality of suction cups for grabbing food are provided at the bottom of the grabbing suction cup arm 7. Combined with the accompanying drawings, the entire material grabbing part is closely attached to the feeding conveyor belt 2, the material pushing part and the material transfer part. The translation slide rail is wrapped and protected by a necessary shell above the vertical frame 6, facing the C-shaped stacking mold 10 and the stacking opening 17 for stacking below, and the grabbing suction cup arm 7 is coordinated with the translation slide rail through a track moving mechanism to make reciprocating linear motion along it. If necessary, the grabbing suction cup arm 7 is connected to the track moving mechanism through an electric lifting structure, so as to ensure that after the suction cup absorbs a sufficient amount of material, it will not be blocked by the C-shaped stacking mold 10 during the material transfer process.

[0033] Combination Figures 1 to 6As shown, as one of the preferred embodiments of the present invention, the material pushing part includes a pushing plate 8 arranged on one side of the feeding conveyor belt 2, a stop plate 9 fixed on the upper surface of the feeding conveyor belt 2, and a C-shaped stacking mold 10 fixed at the far end of the moving direction of the pushing plate 8, the stop plate 9 is paired with a column calculation infrared sensor, and the C-shaped stacking mold 10 is paired with a row calculation infrared sensor. The structure is installed closely to the feeding conveyor belt 2 of the upper station and the material grabbing part of the next station, and the pushing plate 8 driven by the linear motor is provided with a blocking surface perpendicular to the moving direction of the feeding conveyor belt 2. The stop plate 9 allows the materials to reach the stop plate 9 and be blocked in sequence on its blocking surface to form a material column. When the material column roughly meets the required number of materials for boxing a column, the column infrared sensor is sensed to trigger the push plate 8 to push the material column away from the feeding conveyor 2. After being corrected into a neat column by the C-shaped stacking mold 10, the push plate 8 is withdrawn and the next column of materials is pushed again. Under the sensing of the row calculation infrared sensor, the C-shaped stacking mold 10 arranges the number of material columns and rows required for boxing one layer, triggering the adjacent grabbing suction cup arm 7 to absorb a whole layer of materials and transfer them to the stacking platform 16.

[0034] Combination Figures 1 to 6As shown in the figure, as one of the preferred embodiments of the present invention, the material transfer part includes a storage panel 11 mounted between the feeding conveyor belt 2 and the discharging conveyor belt 3, a rotating storage rack 12 arranged below the storage panel 11, and a stacking frame 13 arranged above the storage panel 11. The middle part of the rotating storage rack 12 is connected to the output end of a horizontal rotating mechanism 14 fixed in the frame, and the two ends are symmetrically fixedly connected with a stacking lifting mechanism 15 and a stacking platform 16 arranged at the output end of the stacking lifting mechanism 15. The plate 11 is provided with a stacking opening 17 and a delivery opening 18 corresponding to the stacking elevator 15. The stacking frame 13 matches the delivery opening 18. The food is delivered layer by layer from the stacking opening 17 to the stacking platform 16 below until the number of boxes is reached. The horizontal rotating mechanism 14 drives the rotating rack 12 to switch to the bottom of the delivery opening 18 and then deliver it upward out of the delivery opening 18. The stacked food is pushed to the lifting box position as a whole by the stacking frame 13. In the above structure, the stacking frame 13 is at least The metal frame that holds a box of materials and is transparent from top to bottom is driven by a linear motor mechanism to push the materials that rise from the stacking opening 18 of the storage panel 11 to the subsequent box loading lifting platform 20 that is closely arranged. In the stacking opening 17 and the stacking opening 18, protective side walls are arranged around to prevent the materials from shifting during the lifting process of the stacking platform 16. The axis of the horizontal rotating mechanism 14 can be hinged and fixed to the storage panel 11 to improve its stability. Under horizontal rotation, the stacked materials can be continuously transferred to the subsequent box loading lifting platform 20. At the subsequent cartoning station, when the stacking platform 16 is located below the stacking opening 17, the stacking lifting mechanism 15 descends one layer after each layer of material is loaded, ensuring that the grabbing suction cup arm 7 only needs to move to the same position each time to correctly place the material, until a box of materials is neatly stacked on the stacking platform 16, and then rotated and translated to the bottom of the stacking opening 18, the stacking lifting mechanism 15 raises the stacking platform 16 to send it out to the stacking frame 13, and the stacking frame 13 pushes it to the cartoning lifting platform 20, and the structure is very compact.

[0035] Combination Figures 1 to 10As shown in the figure, as one of the preferred embodiments of the present invention, the lifting and box loading position includes a bracket 19 fixed in the frame 1 and a box loading lifting platform 20 arranged in the bracket 19, the bracket 19 is composed of two vertical plates arranged opposite to each other, and a pair of relatively movable clamping plates 21 are arranged between the two vertical plates. The top of the vertical plate is fixed with a horizontally placed L-shaped limiting plate 22 for limiting the folding edge of the carton board in the flattened state to avoid the problem of package position deviation caused by excessive feeding, and the clamping plate 21 is fixed on a clamping plate rotating shaft 2 erected between the two vertical plates, and the clamping plate 21 is driven to swing around the axis by an electric crank 23 fixed on one side of the vertical plate. 4, as the work station where the boxing steps intersect, the L-shaped limit plate 22 of the bracket 19 allows the flattened carton board to accurately enter the folding position, and then as the boxing lifting platform 20 continues to descend, the folding ears will be bent between the two side clamps 21, and the forming and fixing of the carton will be completed in the mutual extrusion between the clamps 21 and the materials. The hot melt adhesive for folding bonding is sprayed at the adjacent induction hot melt adhesive nozzle 25, so the action is continuous and rapid, and the electric crank 23 can perform the action efficiently and accurately, so that the clamp shaft 24 can accurately and appropriately bend and fix the folding ears of the carton board to avoid crushing the wrapped materials.

[0036] Combination Figures 1 to 3 , Figures 7 to 9 As shown, as a further step of the above embodiment, an induction hot melt glue nozzle 25 fixed on the top of the bracket is provided between the bracket 19 and the electric push plate, and the induction hot melt glue nozzle 25 is symmetrically arranged on both sides of the bracket 19. The induction hot melt glue nozzle 25 is connected to a hot melt glue feeding mechanism 26 installed on the side of the frame 1, and is connected to the glue outlet of the hot melt glue feeding mechanism 26. The hot melt glue feeding mechanism 26 is a conventional hot melt glue feeding unit. The induction hot melt glue nozzle 25 senses whether the glue spraying position of the four corner folding ears of the carton board passes through the nozzle, and sprays hot melt glue at the four positions respectively. The induction hot melt glue nozzle 25 is essentially composed of an infrared sensor and a hot melt glue nozzle, and is centrally controlled by the operating table 4.

[0037] Combination Figures 1 to 3 , Fig.11 As shown, as one of the preferred embodiments of the present invention, the carton material rack 27 is an open metal frame, which is fixed on the surface of a vertical fixed plate 29 installed and fixed on the top of the frame 1 at an angle corresponding to the travel trajectory of the crank suction cup arm. An open opening 28 is provided at the bottom for the flattened carton board to leave the carton material rack 27. The carton material rack 27 has a simple structure and utilizes the characteristic of the carton board itself having a certain degree of flexibility. The crank suction cup arm takes one carton board at a time through the open opening 28 provided at the bottom, and the subsequent carton board stacks will be stuck in the carton material rack 27 by their own weight and are taken out one by one as they are arranged tilted.

[0038] Combination Figures 1 to 3, Fig.11 As shown, as a further step of the above embodiment, the crank suction cup arm is composed of a crank rocker mechanism 30 installed on the surface of the vertical fixed plate 29 and a paper box plate suction cup 31 fixed on the rocker of the crank rocker mechanism 30. The paper box plate suction cup 31 is driven by the crank rocker mechanism 30, and the starting position of the stroke corresponds to the paper box material rack 27, and the end position of the stroke corresponds to the electric push plate. The crank rocker mechanism 30 is shown in the figure, and the action execution is fast and reasonable, the structure is simple and reliable, and it is a mature planar four-bar mechanism. The paper box plate suction cup 31 is convenient for taking the paper box plate.

[0039] Combination Figures 1 to 10 As shown, as a further step of the above embodiment, the electric push plate includes a carton board placement plate 32 fixed on the top of the frame 1, two guide baffles 33 parallel to the top of the carton board placement plate 32, a push plate motor 34 fixed and placed horizontally below the carton board placement plate 32, and a carton board push plate 35 fixed at the output end of the push plate motor 34. The carton board placement plate 32 is provided with a avoidance groove 36 for the carton board push plate 35 to move toward the lifting and lowering box loading position. The starting point of the travel of the carton board push plate 35 corresponds to the end point of the travel of the carton board suction cup 31. The structure of this position is shown in the figure. In essence, it is achieved by sensing the carton board falling to the carton board placement plate 3 2, the carton board push plate 35 is driven by the push plate motor 34 to complete the action of pushing the carton board to the box loading lifting platform 20 / pushing the boxed material box to the discharge conveyor belt 3 for delivery. The guide baffle 33 can ensure that the posture of the carton board is correct and does not fall out. The setting of the avoidance groove 36 prevents the carton board from continuing to fall. As long as the carton board push plate 35 is set to a sufficient height so that it can touch the objects placed on the carton board storage plate 32, the two actions mentioned above can be taken into account, which is very convenient and compact. Alternatively, a discharge pushing mechanism 42 can be separately configured for the feeding conveyor belt 3, which is independent of the push plate motor 34 and does not interfere with each other, and the design requirements for the structural space can be further reduced.

[0040] Combination Figures 1 to 3 , Fig. 9 and Fig.10As shown, as one of the preferred embodiments of the present invention, the bottom of the cartoning lifting platform 20 is connected to a vertical rack 38 through a fixed rod 37, and the rack 38 is engaged with the output end of a rack motor 39 fixed in the frame 1. A vertical lifting rod 40 is fixedly connected to one side of the rack 38, and the stabilizing pressure rod 5 is fixedly connected to the top of the lifting rod 40. A stabilizing pressure plate 41 with a matching size facing the cartoning lifting platform 20 is connected to the bottom of the stabilizing pressure rod 5. The stabilizing pressure rod 41 is coaxial with the fixed rod 37 in the vertical direction. This structure also belongs to a compact layout. The stabilizing pressure plate 41 ensures that the material will not fall apart when being boxed, and the coaxially arranged fixed rod 37 can ensure that the material is subjected to uniform and balanced force. Through the mutual connection between the rack 38 and the lifting rod 40, the stabilizing pressure plate 41 and the cartoning lifting platform 20 can move synchronously, which is also a structural design guarantee of a compact and stable layout.

[0041] To sum up, after the present invention is designed, it is more in line with the actual production needs of the applicant than other existing similar non-standard equipment. The reason is that the overall layout of the present invention can be arranged more compactly, so the layout will show a more reasonable state, and the mechanical structure itself also benefits from the advantages of the compact structure. When executing the actions required by the working steps, no unnecessary actions will be performed, so that the scattered foods in square shapes can be quickly and accurately sent out of the equipment in batches in boxes after the mechanical equipment completes the actions of palletizing, boxing and packaging, for subsequent further packing. From the overall performance, the present invention is clean, neat and accurate in executing the actions of folding carton boards into boxes to wrap the stacked foods, so the work efficiency is high, which can effectively reduce the workload of staff operating the equipment and improve the production efficiency of the enterprise.

[0042] Therefore, in combination with the above-mentioned technical features, the technical features of the present invention are mainly concentrated on the technical element of utilizing the reasonable combination of linkage parts and mechanical actuators, and coordinating with the simplified electronic control structure to make the rapid boxing of small pieces of food a more efficient and easy-to-control mechanical execution process. The whole process has low requirements for the setting of the electronic control unit and the construction of the electronic control system. After the small pieces of food are stacked in sequence, they are directly sent to the packaging paper at the boxing position to complete the steps of paper box forming + material loading in one step. For technical personnel in this field, it is a relatively simple but efficient and reasonable choice among many non-standard mechanical solutions for achieving technical goals.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
