Description

Technical Field

[0001] This invention relates to the field of automated packaging equipment technology, and specifically to an automatic soft bag packaging machine. Background Technology

[0002] In the production process of soft bag products, the products need to be packaged first, and then the packaged products are put into boxes for packaging. Especially in the food industry, packaging is a crucial part of the entire production process. However, traditional boxing operations are mostly manual. The transportation of boxes and cartons, as well as the final packing, consume a lot of manpower and resources, and the packing efficiency is very low, which affects the entire production process.

[0003] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an automatic soft bag packaging machine, thereby effectively solving the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an automatic soft bag packaging machine, comprising a machine body, wherein the machine body includes:

[0006] The product conveying assembly includes an interconnected feed conveyor belt and a conveyor belt, and a push bar is provided at the connection between the two.

[0007] A box conveying assembly includes a box conveyor line, wherein a lifting device is provided on the box conveyor line, the lifting device allowing the boxes to be detached from the conveyor line for product packing.

[0008] The product gripping component includes a suction device and a coordinate robot connected to the suction device. The suction device includes several suction rods arranged in parallel to pick up the product.

[0009] The beneficial effects of this invention are as follows: The automatic soft bag packaging machine designed in this solution can automatically complete the product feeding and conveying, box feeding and conveying, and grabbing products and putting them into boxes for packing operations. It has a high degree of automation, high product packing efficiency, and can effectively improve the production process.

[0010] This design proposes an automatic soft bag packaging machine. The specific workflow is as follows: Products are fed through a feeding conveyor belt. A material-pulling rod is installed at the end of the feeding conveyor belt. The material-pulling rod is driven by a cylinder to move the products from the feeding conveyor belt to the conveyor belt. On the conveyor belt, multiple products are sucked out at a designated position by a suction device. Then, a coordinate robot moves the sucked-out products to the box conveyor line. After the boxes on the box conveyor line move to a designated position, a lifting device lifts the boxes off the box conveyor line. Finally, the suction device, in conjunction with the coordinate robot, places the products into the stationary boxes.

[0011] Furthermore, the product conveying assembly adopts a dual-station structure. The feeding conveyor belt includes a first feeding conveyor belt and a second feeding conveyor belt that are parallel to each other. The conveying conveyor belt includes a first conveying conveyor belt and a second conveying conveyor belt that move parallel to each other. The first feeding conveyor belt is connected to the first conveying conveyor belt, and the second feeding conveyor belt is connected to the second conveying conveyor belt. The dual-station structure allows both conveyor belts to work simultaneously. After the gripping device grips the product on the first conveying conveyor belt and puts it into the box, it can continue to grip the product on the second conveying conveyor belt. During this time period, the first conveying conveyor belt can gather the next batch of products, thereby achieving uninterrupted operation and improving the working efficiency of the equipment.

[0012] Furthermore, the box conveyor line includes a feeding belt conveyor line and a conveying chain conveyor line. The end of the feeding belt conveyor line is connected to the beginning of the conveying chain conveyor line, and a stop bar is provided at the end of the feeding belt conveyor line. The stop bar is connected to a telescopic cylinder. The boxes are first fed through the feeding belt conveyor line. When the boxes reach the end of the feeding belt conveyor line, the stop bar blocks the boxes from entering the conveying chain conveyor line. After the boxes in front move forward, the stop bar retracts, realizing the function of feeding boxes one by one.

[0013] Furthermore, the box conveyor line also includes a drive motor, the output end of which is connected to a rotating shaft. The rotating shaft is equipped with the drive sprocket of the material conveying chain conveyor line, and the rotating shaft is connected to the drive pulley of the feeding belt conveyor line via a synchronous belt. The feeding belt conveyor line and the material conveying chain conveyor line are driven by the same motor, which can ensure that the boxes on the two conveyor belts move at equal or similar speeds, avoiding the extreme situations of the boxes being fed too fast and causing blockage or too slow and resulting in no products.

[0014] Furthermore, the conveyor chain is equipped with several pusher blocks, one pusher block pushes one box, and the distance between two adjacent pusher blocks is equal; the products entering the conveyor chain from the feed belt conveyor are pushed forward by the pusher blocks, and one pusher block stacks one product.

[0015] Furthermore, the lifting device is located at the end of the conveyor chain, and includes a lifting plate and a lifting cylinder connected to the lifting plate. When the box arrives at the designated packaging area, the lifting plate, under the action of the lifting cylinder, lifts the product on the conveyor chain. The lifted product will detach from the pusher block of the conveyor chain and be placed stationary on the lifting plate. The pusher block will not be blocked by the lifting plate and will continue to move forward and return from the end of the conveyor chain to transport the next box. The product on the lifting plate is then placed into the box by the gripping device to complete the product packaging.

[0016] Furthermore, the suction device includes a base, on which a drive assembly capable of translating the suction rod is provided, and a guide plate is provided on the base. The guide plate has several oblong holes, and a slider on a suction rod is inserted into one oblong hole. When the suction rod of the suction device picks up products of different specifications, its position needs to be adjusted by translation on the base. The oblong holes on the guide plate can guide and limit the translation of the suction rod.

[0017] Furthermore, the drive assembly includes a synchronous belt device and a drive motor. The drive motor is connected to the drive pulley of the synchronous belt device. The suction rod is equipped with a clamping mechanism that clamps the belt of the synchronous belt device. The drive motor drives the synchronous belt device to operate, and the belt on the synchronous belt device drives the suction rod to move horizontally.

[0018] Furthermore, the clamping mechanism includes an upper clamping groove and a lower clamping groove. The upper end of the belt is disposed in the upper clamping groove, and the lower end is disposed in the lower clamping groove. An upper push rod threadedly connected to the clamping mechanism is disposed in the upper clamping groove, and a lower push rod threadedly connected to the clamping mechanism is disposed in the lower clamping groove. The upper push rod and the lower push rod can abut against the belt to fix the belt in their respective opposing clamping grooves. The push rods in the upper and lower clamping grooves do not need to clamp the belt simultaneously. The direction in which the suction rod is to move determines which push rod in the clamping groove clamps the belt. Since the push rod is threadedly connected to the clamping mechanism, the up and down movement of the push rod can be controlled simply by turning the push rod knob.

[0019] Furthermore, springs are provided at the ends of both the upper and lower push rods; the springs ensure an elastic connection between the two when the push rods abut against the belt; when the slider on the suction rod moves within the oblong hole, the belt can move the suction rod along with it. However, when the slider reaches the end of the oblong hole, it will be stuck and unable to move. If there were a hard contact between the push rod and the belt, the push rod would block the belt and prevent it from moving. But with the elastic connection, the push rod cannot block the belt, and the belt can overcome sliding friction and continue to move. This structure allows all the suction rods on a row to be adjusted independently without being affected by other suction rods. Only the guide plates with oblong holes of different lengths need to be replaced according to the position adjustment requirements of each suction rod. Attached Figure Description

[0032] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] See appendix Figures 1-3 As shown, an embodiment of the present invention discloses an automatic soft bag packaging machine, including a machine body, the machine body including a product conveying component 1, including an infeed conveyor belt and a conveying conveyor belt that are interconnected, and a material-pulling rod 1.5 is provided at the connection between the two; it also includes a box conveying component 2, including a box conveying line, the box conveying line is provided with a lifting device, the lifting device can detach the box from the conveying line for product packing; it also includes a product gripping component 3, including a suction device and a coordinate robot connected to the suction device, the suction device including a plurality of suction rods 3.2 arranged in parallel for picking up products.

[0034] This solution designs an automatic soft bag packaging machine that can automatically complete product feeding and conveying, box feeding and conveying, and grabbing products to put them into boxes for packing. It has a high degree of automation and high product packing efficiency, which can effectively improve the production process.

[0035] The specific workflow is as follows: Products are fed through the feeding conveyor belt. A material-pulling rod 1.5 is set at the end of the feeding conveyor belt. The material-pulling rod 1.5 is driven by a cylinder to move the products from the feeding conveyor belt to the conveying conveyor belt. The products on the conveying conveyor belt are sucked out by a suction device at a designated position. Then, a coordinate robot moves the sucked-out products to the box conveyor line. After the boxes on the box conveyor line move to a designated position, a lifting device lifts the boxes off the box conveyor line. Finally, the suction device, together with the coordinate robot, puts the products into the stationary boxes.

[0036] In one or more embodiments, such as Figure 2 As shown, the product conveying assembly 1 adopts a dual-station structure. The feeding conveyor belt includes a first feeding conveyor belt 1.1 and a second feeding conveyor belt 1.3 that are parallel to each other. The material conveying conveyor belt includes a first material conveying conveyor belt 1.2 and a second material conveying conveyor belt 1.4 that move parallel to each other. The first feeding conveyor belt 1.1 is connected to the first material conveying conveyor belt 1.2, and the second feeding conveyor belt 1.3 is connected to the second material conveying conveyor belt 1.4.

[0037] The dual-station product conveyor belt allows both conveyor belts to work simultaneously. After the gripping device grabs the product from the first conveyor belt 1.2 and puts it into the box, it can continue to grab the product from the second conveyor belt 1.4. During this time, the first conveyor belt 1.2 can gather the next batch of products, thus achieving uninterrupted operation and improving the working efficiency of the equipment.

[0038] In one or more embodiments, such as Figure 3 As shown, the box conveyor line includes a feeding belt conveyor line 2.1 and a conveying chain conveyor line 2.2. The end of the feeding belt conveyor line 2.1 is connected to the head of the conveying chain conveyor line 2.2, and a stop bar 2.3 is provided at the end of the feeding belt conveyor line 2.1. The stop bar 2.3 is connected to a telescopic cylinder.

[0039] The boxes are first fed through the feeding conveyor belt. When the boxes reach the end of the feeding conveyor belt, the stop bar 2.3 blocks the boxes from entering the material conveyor chain 2.2. After the boxes in front move forward, the stop bar 2.3 is retracted, thus realizing the function of feeding one box at a time.

[0040] In one or more embodiments, such as Figure 4 As shown, the box conveyor line also includes a drive motor 2.4, the output end of which is connected to a rotating shaft 2.5. The rotating shaft 2.5 is equipped with the drive sprocket of the material conveying chain conveyor line 2.2, and the rotating shaft 2.5 is connected to the drive pulley of the feeding belt conveyor line 2.1 via a synchronous belt.

[0041] The feeding belt conveyor 2.1 and the conveying chain conveyor 2.2 are driven by the same motor. This ensures that the boxes on the two conveyor belts move at equal or similar speeds, avoiding the extreme situations of the boxes being fed too fast and causing blockages or being fed too slowly and resulting in no products.

[0042] In one or more embodiments, such as Figure 3 As shown, the material conveying chain 2.2 is provided with a number of push blocks 2.6. Each push block 2.6 pushes a box, and the distance between two adjacent push blocks 2.6 is equal.

[0043] Products entering the conveyor chain from the feed belt conveyor 2.1 are pushed forward by pusher blocks 2.6, with one pusher block 2.6 holding one product.

[0044] In one or more embodiments, such as Figure 3 As shown, the lifting device is located at the end of the material conveying chain 2.2, and includes a lifting plate 2.7 and a lifting cylinder 2.8 connected to the lifting plate 2.7.

[0045] Once the box reaches the designated packaging area, the lifting plate, under the action of the lifting cylinder 2.8, will lift the product on the conveyor chain 2.2. The lifted product will detach from the pusher block 2.6 of the conveyor chain and be placed stationary on the lifting plate. The pusher block 2.6 will not be obstructed by the lifting plate and will continue to move forward and return from the end of the conveyor chain 2.2 to transport the next box. The product on the lifting plate will be placed into the box by the gripping device to complete the product packing.

[0046] In one or more embodiments, such as Figure 5 As shown, the suction device includes a base 3.1, on which a driving component capable of driving the suction rod 3.2 to move horizontally is provided, and a guide plate 3.3 is provided on the base 3.1. The guide plate 3.3 has a plurality of waist-shaped holes 3.4, and a slider provided on a suction rod 3.2 is inserted into one of the waist-shaped holes 3.4.

[0047] When the suction rod 3.2 of the suction device is picking up products of different specifications, its position needs to be adjusted by translation on the base 3.1. The waist-shaped hole 3.4 opened on the guide plate 3.3 can guide and limit the translation of the suction rod 3.2.

[0048] In one or more embodiments, such as Figure 6As shown, the drive assembly includes a timing belt device 3.5 and a drive motor 2.4. The drive motor 2.4 is connected to the drive pulley of the timing belt device 3.5. The suction rod 3.2 is equipped with a clamping mechanism 3.6, which clamps the belt of the timing belt device 3.5. The drive motor 2.4 drives the timing belt device 3.5 to operate, and the belt on the timing belt device 3.5 drives the suction rod 3.2 to move horizontally.

[0049] In one or more embodiments, such as Figure 6 As shown, the clamping mechanism 3.6 includes an upper clamping groove 3.7 and a lower clamping groove 3.8. The upper end of the belt is disposed in the upper clamping groove 3.7 and the lower end is disposed in the lower clamping groove 3.8. An upper push rod 3.9 is disposed in the upper clamping groove 3.7 and is threadedly connected to the clamping mechanism 3.6. A lower push rod 3.10 is disposed in the lower clamping groove 3.8 and is threadedly connected to the clamping mechanism 3.6. The upper push rod 3.9 and the lower push rod 3.10 can abut against the belt to fix the belt in their respective opposing clamping grooves.

[0050] The push rods in the upper clamping groove 3.7 and the lower clamping groove 3.8 do not need to clamp the belt at the same time. The direction of movement of the suction rod 3.2 determines which push rod in which clamping groove clamps the belt. Since the push rod and the clamping mechanism 3.6 are connected by a thread, the push rod can be moved up and down by simply turning the knob.

[0051] In one or more embodiments, the ends of the upper push rod 3.9 and the lower push rod 3.10 are provided with springs; the springs ensure that the two are elastically connected when the push rods abut against the belt.

[0052] When the slider on the suction rod 3.2 moves within the oblong hole 3.4, the belt can move the suction rod 3.2 along with it. However, when the slider reaches the end of the oblong hole 3.4, it will be stuck and unable to move. If there is a hard contact between the push rod and the belt, the push rod will press against the belt, preventing it from moving. However, with an elastic connection, the push rod cannot press against the belt, and the belt can overcome sliding friction and continue to move. This structure allows all the suction rods 3.2 in a row to be adjusted independently without being affected by other suction rods 3.2. Only the guide plate 3.3 with oblong holes 3.4 of different lengths needs to be replaced according to the position adjustment requirements of each suction rod 3.2.

[0053] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
