Description

Technical Field

[0001] The utility model relates to the field of food packaging conveyor lines, in particular to a food packaging quantitative counting conveyor line. Background Art

[0002] After the food is independently packaged, it needs to be bagged in the same direction in a quantitative manner. Before bagging, the food single bag needs to be cut into individual individual bags, and multiple food single bags need to be bagged in the same direction in a quantitative manner. Traditionally, food is packaged manually. This operation method has the disadvantages of low packaging efficiency, poor packaging effect, high labor intensity for workers, and high labor costs for enterprises. In order to solve the above technical problems, equipment that can automatically package food has appeared on the market. However, this type of equipment does not have the function of direction recognition and length recognition when bagging food single bags. In addition, since the number of food single bags is different, it is easy for large bags to be uneven when the number of single bags is too much or too little, which makes it difficult to transport and store. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a food packaging quantitative counting conveyor line.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solution: the food packaging quantitative counting conveyor line includes a frame, on which a length detection mechanism, a screening mechanism, a counting mechanism and a bagging mechanism are connected in sequence, and a large packaging bag for bagging a quantitative single-bag packaging product is provided under the bagging mechanism.

[0005] By adopting the above-mentioned technical solution, the length detection mechanism detects the length of the conveyed single-bag packaged products. If the length of the packaged product detected by the length detection mechanism is greater than a predetermined length, it indicates that the packaged product being inspected contains two or more single bags connected together. If the length of the packaged product detected by the length detection mechanism is less than a predetermined length, it indicates that the packaged product is placed in the wrong orientation. The screening mechanism screens and conveys the packaged products conveyed by the length detection mechanism. The counting mechanism counts the packaged products conveyed from the screening mechanism until the number of packaged products conveyed reaches the bagging limit, stopping the bagging mechanism from conveying packaged products. The bagging mechanism adjusts the bagging direction of the packaged products conveyed from the counting mechanism and reaches the predetermined number before automatically bagging them.

[0006] Preferably, the length detection mechanism includes a first conveyor line, a first motor, a positioning frame, a first photoelectric detection switch, and a second photoelectric detection switch. The first conveyor line is laterally fixedly mounted on the positioning frame or the first conveyor line is obliquely fixedly mounted on the positioning frame. The first motor is arranged on one side of one end of the first conveyor line, and the first motor is connected to the first conveyor line through a first pulley kit. A first side baffle is provided on the side of the first conveyor line with a lower horizontal position. A slot plate mounting plate is provided on the side of the first side baffle facing away from the first conveyor line, and a positioning slot plate is provided on the upper end of the slot plate mounting plate. The first photoelectric detection switch and the second photoelectric detection switch are sequentially arranged above the first conveyor line along the direction of conveyance of the packaged product, and the first photoelectric detection switch and the second photoelectric detection switch are respectively mounted on the two ends of the positioning slot plate. The first photoelectric detection switch and the second photoelectric detection switch can both adopt the photoelectric switch sensor model EX-23-PN, but are not limited to this.

[0007] By adopting the above technical solution, when packaged products are placed on the first conveyor line, the first motor, via the first pulley assembly, drives the first conveyor line to rotate and convey the packaged products. By positioning the first conveyor line at an angle toward the first side guard, the packaged products conveyed on the first conveyor line can be conveyed against the first side guard. When the first and second photoelectric detection switches simultaneously and continuously detect a packaged product, it indicates that the packaged product being conveyed contains two or more conjoined individual packages, and this packaged product needs to be rejected in the next step. When the first and second photoelectric detection switches only momentarily detect a packaged product, it indicates that the packaged product being conveyed is a single individual packaged product, suitable for bagging, and can be conveyed to the subsequent station for bagging. When the first and second photoelectric detection switches simultaneously detect no packaged product, it indicates that the packaged product being conveyed is placed horizontally or vertically on the first conveyor line. Such a packaged product is incorrectly oriented and does not meet bagging requirements, and needs to be rejected. The length detection mechanism is designed to fully automatically detect the length and placement of the packaged product, facilitating the automatic rejection of packaged products that do not meet bagging requirements.

[0008] Preferably, the screening mechanism includes a second conveyor line, a second side baffle is vertically provided on one side of the second conveyor line, a carrier is provided on the other side of the second conveyor line, and the second conveyor line and the carrier are arranged in parallel, and a sorting trough is obliquely provided on the carrier; an air nozzle mounting plate is provided on the side of the second conveyor line away from the carrier, an air nozzle is provided on the air nozzle mounting plate, the air nozzle is externally connected to an air supply device, and an electromagnetic valve is provided on one side of the air nozzle mounting plate; a second motor is provided on one side of one end of the second conveyor line, and the second motor is connected to the second conveyor line through a second pulley kit. The composition structure and working principle of the air supply device are common knowledge and will not be explained in detail here.

[0009] By adopting the above-mentioned technical solution, the second motor drives the second conveyor line to rotate through the second pulley kit to convey the packaged products conveyed from the first conveyor line. The second conveyor line is arranged to be distributed in parallel with the carrier. Since the width of the second conveyor line is comparable to the width of the packaged products, if the packaged products are placed obliquely on the second conveyor line and conveyed to the sorting trough, they will automatically fall out of the sorting trough for recovery due to weight loss, so that they can automatically remove incorrectly placed packaged products. When the packaged products conveyed on the second conveyor line are two or more independent packaging bags connected together, the air nozzle external air supply device can blow air on the packaged products conveyed through it, so that the connected packaged products can be blown off from the second conveyor line by the air nozzle to the sorting trough for unloading and recovery. The structural design of the screening mechanism can automatically remove packaged products that do not meet the bagging requirements.

[0010] Preferably, the counting mechanism includes a third conveyor line, a third side baffle provided on one side of the third conveyor line, a fourth side baffle provided on the other side of the third conveyor line, a mounting bracket provided on the fourth side baffle, and a counting sensor provided on the mounting bracket; a third motor provided below one end of the third conveyor line, the third motor being drivenly connected to the third conveyor line via a third pulley assembly. The counting sensor may be, but is not limited to, a model SN04-N counting sensor.

[0011] By adopting the above-mentioned technical solution, the third motor drives the third conveyor line to rotate through the third pulley kit to convey the packaged products that have been screened and meet the bagging requirements and are transmitted from the second conveyor line. The counting sensor automatically counts the packaged products transmitted through it, and the third conveyor line conveys the packaged products counted by the counting sensor into the bagging mechanism. The structural design of the counting mechanism can realize the conveyance of a set number of packaged products to the bagging mechanism to ensure that the number of packaged products bagged by the bagging mechanism each time can remain consistent.

[0012] Preferably, the bagging mechanism includes a storage box, the upper part of which is provided with a first storage component for bagging and swinging the packaged product, and the lower part of the storage box is provided with a second storage component for bagging the packaged product after a second bagging and swinging adjustment.

[0013] The cam is connected to the second end of the lifting link, and the cam is connected to the first end of the lifting link, and the cam is connected to the first end of the lifting link.

[0014] By adopting the above-mentioned technical solution, the first cylinder of the first storage assembly pulls the first rocker arm and the second rocker arm to swing downward synchronously through the slider and the first guide pin of the first linear sliding assembly in turn, and the downward-swinging first rocker arm and the second rocker arm respectively drive the rotating shaft of the first bearing assembly and the rotating shaft of the second bearing assembly connected thereto to rotate downward synchronously relative to each other to drive the first gate plate and the second gate plate to open towards each other, so that the first batch of independently packaged products transmitted from the third conveyor line of the counting mechanism into the first storage assembly for storage can fall from the gap between the opened first gate plate and the second gate plate onto the second storage assembly, and the first gate plate and the second gate plate can perform the first unloading and swinging adjustment on the independently packaged products passing through the gap between them, so that the independently packaged products are balanced with the gap between the first gate plate and the second gate plate, and the first batch of independently packaged products fall onto the second storage assembly after the unloading and swinging adjustment of the first storage assembly. On the contrary, when the first cylinder of the first storage assembly pushes the first rocker arm and the second rocker arm to swing upward and reset synchronously through the slider and the first guide pin of the first linear sliding assembly in sequence, the upward-swinging first rocker arm and the second rocker arm respectively drive the rotating shaft of the first bearing assembly and the rotating shaft of the second bearing assembly connected thereto to rotate upward synchronously relative to each other (i.e., rotate in the opposite direction) to drive the first gate plate and the second gate plate to close towards each other, preparing for the storage of the second batch of independently packaged products, and the cycle continues.

[0015] The lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of

[0016] By adopting the above technical solution, after the first storage component completes the storage of the second batch of packaged products, the first storage component controls the first and second gates to open according to the above method to adjust the unloading direction of the second batch of independently packaged products. Since a large packaging bag is provided under the second storage component of the bagging mechanism, whenever the second storage component completes the storage of two batches of independently packaged products, the second cylinder of the second storage component sequentially pulls the third and fourth swing arms synchronously downward through the slider and the second guide pin of the second linear sliding component. The downwardly swinging third and fourth swing arms respectively drive the rotating shafts of the third bearing assembly and the fourth bearing assembly connected thereto to rotate synchronously downward relative to each other to drive the third and fourth gates to open oppositely at the same time to perform the second unloading direction adjustment for the two batches of independently packaged products before bagging. After the second storage component simultaneously completes the storage, unloading direction adjustment and bagging of the two batches of independently packaged products, it completes the bagging operation of the independently packaged products into a single large bag.

[0017] Preferably, the first bearing assembly and the third bearing assembly are arranged on the same side of the storage box, and the second bearing assembly and the fourth bearing assembly are arranged on the same side of the storage box.

[0018] By adopting the above-mentioned technical solution, the structure in which the first bearing assembly and the third bearing assembly are arranged on the same side and the second bearing assembly and the fourth bearing assembly are arranged on the same side can maximize the utilization of the space of the storage box, so that it can ensure that the first storage assembly and the second storage assembly work without affecting each other and reduce the volume of the storage box, thereby reducing the production cost of the equipment.

[0019] Preferably, a controller or control system is provided for signal control of the length detection mechanism, screening mechanism, counting mechanism, and bagging mechanism. The controller is a PLC programmable logic controller. The PLC programmable logic controller may be an XDS-40T-D programmable logic controller, but is not limited thereto. An operator can control the automated operation of each mechanism by inputting production parameters for controlling the operation of each mechanism into the controller or control system.

[0020] It should be noted that the first pulley kit, the second pulley kit and the third pulley kit each include two pulleys, and the two pulleys are connected by a belt. The first linear sliding assembly and the second linear sliding assembly each include a slide rail or a guide rail, and a slider sliding on the slide rail or the guide rail. The first bearing assembly, the second bearing assembly, the third bearing assembly and the fourth bearing assembly each include a bearing seat and a rotating shaft passing through the center of the bearing seat. The first pulley kit, the second pulley kit, the third pulley kit, the first linear sliding assembly, the second linear sliding assembly, the first bearing assembly, the second bearing assembly, the third bearing assembly and the fourth bearing assembly are all commonly used components in industrial design, and their working principles are common knowledge and will not be explained in detail here. The slot plate mounting plate and the air nozzle mounting plate are both functional descriptions of the mounting plate. The positioning slot plate and the sorting trough are functional descriptions of the positioning plate and the sorting trough, respectively.

[0021] Compared with the existing technology, the beneficial effects of the present invention are:

[0022] 1. The length detection mechanism is designed so that the distance between the first photoelectric detection switch and the second photoelectric detection switch on the positioning slot plate can be adjusted to detect packaged products of different lengths, thereby achieving its high versatility. The first conveyor line is arranged laterally to facilitate the balance between the packaged products and the first conveyor line, thereby ensuring that the first photoelectric detection switch and the second photoelectric detection switch can correctly detect the length of the packaged products, thereby avoiding the phenomenon that the first photoelectric detection switch and the second photoelectric detection switch incorrectly detect the true length of the packaged products due to the packaged products being placed obliquely on the first conveyor line.

[0023] 2. Through the design of the structure of the screening mechanism, the screening mechanism can directly convey the packaged products that the length detection mechanism detects as meeting the bagging requirements into the counting mechanism, while the packaged products that the length detection mechanism detects as having the wrong direction will automatically fall from the sorting trough for recovery due to balance loss during the conveying process; and the packaged products that the length detection mechanism detects as not meeting the bagging requirements will be blown by an air nozzle to fall into the sorting trough for unloading and recovery, so that the packaged products that do not meet the bagging requirements can be automatically rejected to ensure the accuracy of bagging.

[0024] 3. The counting mechanism is designed so that the packaged products are automatically dropped into the bagging mechanism while the number of packaged products is being measured by the counting sensor. The bagging mechanism can then be bagged only after a sufficient or preset number of packaged products have been delivered to it, ensuring that the number of products packed in each large bag remains consistent.

[0025] 4. The structure of the bagging mechanism is designed. The bagging mechanism adjusts the direction of the packaged product twice before bagging to ensure that the packaged product can be bagged according to the bagging requirements, and the counting mechanism accurately counts the bagged number of packaged products. It enables independently packaged products to be quantitatively and directionally loaded into large packaging bags to ensure the flatness of the packaged products after bagging, so that the large packaging bags have the advantages of neat packaging, compact packaging and high packaging efficiency, which makes it convenient to transport and store them, and can reduce packaging costs, transportation costs and storage costs; the length detection mechanism, screening mechanism, counting mechanism and bagging mechanism are used in combination to effectively solve the problem that the food packaging equipment on the market lacks the function of direction recognition, length recognition and screening of single packaging bags when bagging, which leads to uneven packaging of large packaging bags, inconvenient transportation and inconvenient storage.

The second cylinder 88 pulls the third rocker arm 85 and the fourth rocker arm 86 to swing up and down to drive the third gate plate 81 and the fourth gate plate 82 to open and close in opposite directions.

[0046] In another embodiment, the structural design principle and workflow of the food packaging quantitative counting conveyor line are as follows: first, packaged products to be packed into large bags are placed onto the first conveyor line 21 of the length detection mechanism 2. When the first conveyor line 21 rotates via a first pulley assembly 24 and is driven by a first motor 22, it conveys the packaged products placed thereon. By positioning the first conveyor line 21 laterally on a positioning frame 23 and providing a first side baffle 25 on the lower side of the laterally positioned first conveyor line 21, the packaged products can be conveyed against the first side baffle 25 during conveyance along the first conveyor line 21. The length detection mechanism 2 detects the length of each individual bag of the packaged product being conveyed. This is achieved by providing a first photoelectric detection switch 28 and a second photoelectric detection switch 29 above the first conveyor line 21. When the first and second photoelectric detection switches 28 and 29 simultaneously and continuously detect a packaged product, it indicates that the length of the packaged product being conveyed exceeds a predetermined or set length, indicating that two or more independent packages are connected. Such a packaged product does not meet the bagging requirements and must be rejected. When the first photoelectric detection switch 28 and the second photoelectric detection switch 29 detect the packaged product simultaneously and momentarily, it means that the packaged product currently being conveyed is a single independent packaged product, which meets the requirements for bagging. The packaged product currently being conveyed can continue to be conveyed to the subsequent station for bagging by the bagging mechanism 5. When the first photoelectric detection switch 28 and the second photoelectric detection switch 29 do not detect the packaged product simultaneously, it means that the length of the packaged product currently being conveyed is less than the predetermined or set length. The orientation of the packaged product currently being inspected on the first conveyor line 21 is incorrect. The orientation of this packaged product does not meet the requirements for bagging and needs to be rejected. The length detection mechanism 2 can automatically detect whether the packaged product being conveyed meets the requirements for bagging.

[0047] When the packaged products are conveyed from the length detection mechanism 2 to the screening mechanism 3, the screening mechanism 3 screens and conveys the packaged products conveyed by the length detection mechanism 2. The packaged products are conveyed along the second conveyor line 31 and driven by the second motor 38. The screening mechanism 3 can automatically screen the packaged products based on the length sensing signals of the packaged products detected by the first photoelectric detection switch 28 and the second photoelectric detection switch 29. When the packaged products with the wrong placement direction are conveyed on the second conveyor line 31 of the screening mechanism 3 and pass through the sorting trough 34, they will lose balance and automatically fall from the sorting trough 34 for recovery. An air nozzle mounting plate 35 is provided on the side of the second conveyor line 31 away from the carrier 33, and an air nozzle 36 is provided on the air nozzle mounting plate 35. The air nozzle 36 is externally connected to an air supply device to blow air to the packaged products that are conveyed through it and have more than two independent packaging bags connected, so that the packaged products can be blown away by the air nozzle 36 and fall into the sorting trough 34 for unloading and recycling; and the packaged products that meet the bagging requirements are conveyed into the counting mechanism 4 through the second conveyor line 31 of the screening mechanism 3, which can automatically eliminate the packaged products that do not meet the bagging requirements and automatically continue to convey the packaged products that meet the bagging requirements.

[0048] When the packaged products are conveyed from the second conveyor line 31 of the screening mechanism 3 to the third conveyor line 41 of the counting mechanism 4, the counting sensor 45 of the counting mechanism 4 can count the packaged products conveyed from the screening mechanism 3. When the counting sensor 45 calculates that the number of packaged products conveyed reaches the bagging number, it will send an induction signal to the controller. After receiving the counting signal from the counting sensor 45, the controller controls the third motor 46 of the counting mechanism 4 to stop working to stop the bagging mechanism 5 from continuing to convey the packaged products. The counting mechanism 4 can ensure that the number of bagged packaged products remains consistent.

[0049] When the packaged products are conveyed from the third conveyor line 41 of the counting mechanism 4 to the bagging mechanism 5, the first storage assembly 7 and the second storage assembly 8 are respectively provided on the storage box 6 of the bagging mechanism 5 from top to bottom. The first storage assembly 7 of the bagging mechanism 5 stores the independently packaged products in batches and adjusts the unloading direction. The first batch of independently packaged products are blocked on the first storage assembly 7 for independently packaged product storage. After the independently packaged products are stored in sufficient quantity or reach a preset quantity, the first cylinder 78 of the first storage assembly 7 pulls the first swing rod 75 and the second swing rod 76 to swing downward synchronously. The downward-swinging first swing rod 75 drives the rotating shaft of the first bearing assembly 73 to rotate downward, and the downward-swinging second swing rod 76 drives the rotating shaft of the second bearing assembly 74 to rotate downward synchronously. , so that the first gate plate 71 is driven by the rotating shaft of the first bearing assembly 73 and the second gate plate 72 is driven by the rotating shaft of the second bearing assembly 74 to open the gates and discharge the materials synchronously. The first batch of independently packaged products can fall from the gap between the opened first gate plate 71 and the second gate plate 72 onto the second storage assembly 8. When the independently packaged products pass through the gap between the first gate plate 71 and the second gate plate 72, the first gate plate 71 and the second gate plate 72 can adjust the unloading direction of the independently packaged products, so that the independently packaged products can be transported in a balanced manner with the gap between the first gate plate 71 and the second gate plate 72 and complete the unloading direction adjustment for them, that is, the first storage assembly 7 completes the unloading direction adjustment for the first batch of independently packaged products during the process of them falling onto the second storage assembly 8. Then, the first cylinder 78 in the first storage assembly 7 pulls the first swing arm 75 and the second swing arm 76 to swing upward synchronously. The upwardly swinging first swing arm 75 and the second swing arm 76 respectively drive the rotating shaft of the first bearing assembly 73 and the rotating shaft of the second bearing assembly 74 connected thereto to rotate upward synchronously relative to each other to drive the first gate plate 71 and the second gate plate 72 to close towards each other, so that the first storage assembly 7 starts to store the second batch of independently packaged products or starts to store the next batch of independently packaged products.

[0050] When the first storage assembly 7 unloads two batches of independently packaged products onto the second storage assembly 8, the second cylinder 88 of the second storage assembly 8 pulls the third swing rod 85 and the fourth swing rod 86 to swing downward synchronously, and the downwardly swinging third swing rod 85 and the fourth swing rod 86 respectively drive the rotating shaft of the third bearing assembly 83 and the rotating shaft of the fourth bearing assembly 84 connected thereto to rotate downward synchronously relative to each other to drive the third gate plate 81 and the fourth gate plate 82 to open toward each other at the same time, so that the two batches of independently packaged products on the second storage assembly 8 can be unloaded from the opened third storage assembly 8. The gap between the third gate 81 and the fourth gate 82 is used for transmission. When the individually packaged products are balanced and transmitted through the gap between the third gate 81 and the fourth gate 82, the third gate 81 and the fourth gate 82 can also adjust the direction of the individually packaged products. Since the lower end of the second storage assembly 8 of the bagging mechanism 5 is equipped with a large packaging bag, when the third gate 81 and the fourth gate 82 are opened, they can not only perform a second adjustment of the direction of the two batches of individually packaged products before bagging, but also automatically bag the two batches of individually packaged products at the same time. After the two batches of individually packaged products are bagged, the second cylinder 88 of the second storage assembly 8 pulls the third swing arm 85 and the fourth swing arm 86 to swing upward synchronously. The upward swinging third swing arm 85 and the fourth swing arm 86 respectively drive the rotating shaft of the third bearing assembly 83 and the rotating shaft of the fourth bearing assembly 84 connected thereto to rotate synchronously upward relative to each other, driving the third gate 81 and the fourth gate 82 to close the gates towards each other in preparation for storing the next two batches of individually packaged products.

[0051] When the first storage component 7 is storing materials for the third batch of independently packaged products, the third gate 81 and the fourth gate 82 of the second storage component 8 are opened and the first two batches (i.e., the first batch and the second batch) of independently packaged products are adjusted for the second time before bagging and the first two batches of independently packaged products that have completed the second swing adjustment are bagged. After the bagging of the first two batches of independently packaged products is completed, the third gate 81 and the fourth gate 82 of the second storage component 8 are immediately closed to prepare for the storage of the next two batches (i.e., the third batch and the fourth batch) of independently packaged products. At this time, it completes the operation of automatically bagging multiple independently packaged products with a single large packaging bag. Such a cycle enables the independently packaged products to be quantitatively and directionally loaded into the large packaging bag, and the packaging is neat and compact, which is convenient for transportation and storage, thereby reducing packaging costs, transportation costs and storage costs.

[0052] The overall structural design realizes the automatic operation of length detection, screening and conveying, counting, first direction adjustment before bagging, secondary direction adjustment before bagging and bagging of independently packaged products in one body. It has the functions of automatically identifying the length of independently packaged products, automatically identifying the direction of independently packaged products, automatically counting the number of independently packaged products, automatically adjusting the secondary direction of independently packaged products and automatically bagging a certain amount of independently packaged products. It can ensure that the quantity and direction of independently packaged products in each large bag are consistent, so as to ensure that the bagging effect of each large bag is flat, which is convenient for transportation and storage. It has the advantages of high bagging efficiency, good bagging effect and high degree of bagging automation. It not only solves the problems of low bagging efficiency, poor bagging effect, high labor intensity of workers and high labor cost of enterprises caused by traditional manual bagging of packaged products, but also solves the problems of uneven bagging of large bags, which is not conducive to transportation and storage due to the lack of direction recognition and length recognition functions for single bags in food packaging equipment on the market.

Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
