Description

Technical Field

[0001] The utility model relates to the field of bag making machines, in particular to a rope outer eversion quality inspection rope threading machine. Background Art

[0002] In the production process of paper bags, the string threading process is an important link. The traditional string threading method of paper bags has problems such as low efficiency and loose string threading. In particular, the string body and the bag body are fixed by gluing. The traditional string body is directly fixed to the inner surface of the bag body sheet after stringing. Therefore, it is necessary to use a quick-drying glue to quickly fix the string body and the bag body to facilitate the next process. Regardless of whether the subsequent folding piece is glued or not, after the bag is loaded with the material, the force-bearing surface between the string body and the bag body is mainly between the string body and the bag body sheet. However, due to the characteristics of quick-drying glue, its adhesion strength and aging resistance are poor, resulting in the fixation between the string body and the bag body sheet not being strong enough. Especially after being placed for a long time, the rope is easy to fall off when the bag is under load.

[0003] At the same time, traditional stringing and bag-folding machines are not perfect at inspecting the stringing quality. If there is a defect in the stringing or the fixing of the string to the bag, the subsequent bag-folding process will continue. The final product is difficult to effectively screen out the bags with stringing defects through equipment or the naked eye, affecting the overall quality of the product. Or, when a defect appears, the machine needs to be stopped and the corresponding bags need to be manually removed, which greatly slows down the bag processing efficiency. Therefore, a string-folding machine with external eversion inspection is needed to solve the problem of difficulty in distinguishing defective bags after quality inspection. Utility Model Content

[0004] The utility model aims at the shortcomings of the prior art and provides a rope-outward-turning quality inspection and stringing machine.

[0005] To solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] The rope outward eversion quality inspection rope threading machine includes a bag conveying device, a rope threading device is provided on the conveying path of the bag conveying device, the rope threading device includes a processing platform, a rope pulling mechanism, a rope cutting device, a rope rotating mechanism, a rope threading mechanism, and an outward eversion mechanism. The processing platform is used to lay out the bag body sheet material, and a rope threading station is provided on the processing platform; the rope pulling mechanism is provided on both sides of the y-axis direction of the processing platform, and the rope pulling mechanism includes a rope pulling clamp movable along the x-axis direction, and is used to pull the bag rope out to a preset length; the rope cutting device is used to cut the bag rope pulled out to a preset length; the rope rotating mechanism includes left and right rope taking clamps, and the rope taking clamp is connected to a clamp rotating mechanism The power source is that the left and right rope taking clamps clamp the bag rope near the rope pulling clamp and the rope cutting device respectively, and the clamp rotation power source drives the rope taking clamp to clamp the bag rope cut by the rope cutting device and rotate it to the bottom of the bag body sheet, corresponding to the position of the bag body rope threading hole; the rope threading mechanism includes a rope threading part, and the rope threading part corresponds to the bag body rope threading hole opened on the folding piece on the outside of the bag body sheet on the processing platform. The rope threading part uses a clamping or pushing method to make the bag rope head pass through the rope threading hole from the bottom of the bag body sheet and be above the bag body sheet; the eversion mechanism includes an eversion pushing head, which can move inward and outward, and is used to push the bag rope passing through the rope threading hole to the gluing position outside the rope threading hole.

[0007] A gluing device is also provided, which includes an outward-turned gluing head for pre-gluing the gluing area outside the rope hole corresponding to the folding piece of the bag body. The gluing area of the outward-turned gluing head passes through the center line of the rope hole of the bag body in the y-axis direction.

[0008] A quality inspection device is provided downstream of the rope threading device, which is used to detect the status of the bag rope on the bag body sheet. The quality inspection device has a pass state and a fail state.

[0009] Downstream of the quality inspection device are a folding device and a forming device, respectively, for folding the top edges of the bag sheet, which has been threaded with the bag string, before forming it. The quality inspection device is located between the two folding devices. If the bag sheet passes the quality inspection device and passes, the subsequent folding and forming devices operate normally. If at least one side of the bag sheet fails the quality inspection device, the folding device on that side stops functioning. The other side can choose to stop or operate normally. This allows bags that pass or fail quality inspection to be distinguished in subsequent processing, facilitating the screening of bags with flawed stringing. It also makes it easier for staff to distinguish and screen out bags that are open and un-folded. This eliminates the need for subsequent folding of bags that pass quality inspection, which can result in waste and blur the distinction between bags that pass and fail, leading to labor-intensive screening and a waste of time.

[0010] Preferably, when at least one side of the bag sheet fails the inspection by the quality inspection device, the subsequent folding device stops working on the bag sheet and operates normally when it passes through the forming device. The folding device includes a folding glue spraying device and corresponding components for folding the bag upper edge.

[0011] Preferably, the outward-turning mechanism includes an outward-turning mounting beam extending along the x-axis and connected to an outward-turning power source. The outward-turning pusher slidably engages the outward-turning mounting beam and is capable of rising and falling relative to the outward-turning mounting beam. This structural design enables the outward-turning pusher to accurately push or clamp the bag rope passing through the rope threading hole to the side of the pre-glued flap of the bag body, ensuring smooth rope threading and gluing processes.

[0012] Preferably, the outward-turning mounting beam is connected to the outward-turning power source through a connecting rod, which is a rotating power source. One end of the connecting rod is hinged to the output end of the outward-turning power source, and the other end of the connecting rod is hinged to the rotating shaft fixed on the outward-turning mounting beam.

[0013] Preferably, at least one of the left and right rope-taking chucks is connected to an internal driving force source, which drives the left and right rope-taking chucks to move closer or farther apart to adjust the rope-taking position. This facilitates adjustment of the rope-taking position according to the size of the bag and the location of the rope-threading hole, improving the versatility of the device and resolving the problem of difficulty in flexibly adjusting the rope-taking position according to the size and location of the rope-threading hole when threading the rope on bags of different sizes.

[0014] Preferably, the rope-pulling mechanism further includes a rope-positioning member for positioning one end of the rope, with the other end of the rope being pulled out by a rope-pulling clamp connected to a translational force source. The rope-positioning member positions one end of the rope, while the rope-pulling clamp pulls out the other end, thereby ensuring the accuracy of the rope length.

[0015] Preferably, the internal driving force source includes left and right synchronous wheels and an internal pushing belt mounted on the synchronous wheels on both sides, and the left and right rope taking clamps are respectively connected to different front and rear sides of the internal pushing belt.

[0016] Preferably, an inner push mounting seat is provided below the processing platform, the inner push mounting seat is slidably arranged on the inner push slide rail through an inner push slider, and the inner push mounting seat is installed with a chuck rotation power source.

[0017] Preferably, the chuck rotation power source is connected to a rotating swing arm that is rotatable relative to the inward push mounting seat.

[0018] Preferably, the left and right inner push mounting seats are connected to different front and rear sides of the inner push belt through clamping blocks respectively.

[0019] Preferably, the rope chuck and the rope threading mechanism are separately mounted on a rotating swing arm, with the rope threading member located below the rope chuck. The rope chuck and the rope threading mechanism can share a common power source. When the rope chuck grips the rope and rotates below the rope threading hole, the rope threading member is also located below the rope threading hole. Furthermore, when the bag size or the position of the rope threading hole changes, the internal driving force source can also synchronously adjust the rope threading member and the rope chuck.

[0020] Preferably, the rope cutting device is an ultrasonic cutting device, which can quickly and accurately cut the bag rope with a smooth cut, which is beneficial for the subsequent rope threading and gluing processes.

[0021] Preferably, the processing platform is equipped with an anti-deviating component for fixing the bag sheet by adsorption or pressure.

[0022] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0023] By arranging the rope body outward turning device, the outward turned rope body is convenient for subsequent quality inspection device to detect because the head portion is located at a position closer to the outer edge of the bag sheet.

[0024] The rope external eversion device can apply quick-drying glue to the non-main stress-bearing surfaces of the bag body and the rope body, which is convenient for subsequent operations. A more time-consuming but more durable and higher connection strength fixing method can be used on the rope fixed to the bag body and the other main stress-bearing surface of the bag body after eversion, such as coating reinforcing glue, thereby improving the load-bearing capacity of the bag.

[0025] A quality inspection device is added to detect the outward-turned rope body. Different subsequent processing techniques are adopted for bags of different qualities according to the inspection results, so that bags with rope threading defects can be quickly screened out from the surface of the bag body, thereby improving the overall quality of the product.

[0026] In addition, the internal driving force source drives the left and right rope-taking clamps to move closer or away, and the rope-taking position can be flexibly adjusted according to the size of the bag body and the position of the rope hole, thereby improving the versatility and applicability of the equipment.

DETAILED DESCRIPTION

[0034] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] Rope external eversion quality inspection rope threading machine, such as Figure 1-6As shown, it includes a bag conveying device, and a rope threading device 3 is provided on the conveying path of the bag conveying device, which is characterized in that the rope threading device 3 includes a processing platform 31, a rope pulling mechanism 32, a rope cutting device 33, a rope rotating mechanism, a rope threading mechanism 36, and an eversion mechanism 38. The processing platform 31 is used to lay out the bag sheet 90, and a rope threading station is provided on the processing platform 31; the rope pulling mechanism 32 is arranged on both sides of the y-axis direction of the processing platform 31, and the rope pulling mechanism 32 includes a rope pulling clamp 321 movable along the x-axis direction, for pulling the bag rope to a preset length; the rope cutting device 33 is used to cut the bag rope pulled to a preset length; the rope rotating mechanism includes left and right rope taking clamps 34, the rope taking clamp 34 is connected to a clamp rotation power source 35, and the left and right rope taking clamps 34 are respectively close to the rope pulling clamp 321 and the rope cutting device 33 The bag rope is clamped at the bag body, and the chuck rotating power source 35 drives the rope taking chuck 34 to clamp the bag rope cut by the rope cutting device 33 and rotate it to the bottom of the bag body sheet 90, corresponding to the position of the bag body rope threading hole 97; the rope threading mechanism 36 includes a rope threading part 361, and the rope threading part 361 corresponds to the bag body rope threading hole 97 opened on the folding piece 96 on the outside of the bag body main sheet 93 on the processing platform 31. The rope threading part 361 clamps or pushes the bag rope end from the bottom of the bag body sheet 90 through the rope threading hole 97 and is above the bag body sheet 90; the outward turning mechanism 38 includes an outward turning pusher 381, which can move inward and outward to push the bag rope passing through the rope threading hole to the gluing position outside the rope threading hole 97, wherein the inward and outward movement can be a lateral movement, a downward pressure or a folding line movement of rising, lateral movement, and downward pressure, or a hinge-like flipping movement.

[0037] A gluing device 7 is also provided, which includes an outward-turned gluing head for pre-gluing the gluing portion of the bag body folding piece 96 corresponding to the outer side of the rope threading hole 97, and the gluing area of the outward-turned gluing head passes through the center line of the bag body rope threading hole 97 in the y-axis direction;

[0038] The outward-turning gluing head for pre-gluing the folding piece 96 is a quick-drying glue gluing head. The glue can dry quickly, so that the rope body and the bag folding piece 96 can be quickly bonded, making it easy for the bag body and the rope body to enter the next process in a fixed state, thereby improving production efficiency.

[0039] Downstream of the quality inspection device 4, a folding device 5 and a forming device 6 are sequentially provided for folding the upper ends of the bag body sheet with the bag string through 90 degrees and then forming the bag body sheet.

[0040] The outward-turning mechanism 38 includes an outward-turning mounting beam 382 extending along the x-axis and connected to an outward-turning power source 383. An outward-turning pusher 381 slidably engages with the outward-turning mounting beam 382 and can be raised and lowered relative to the outward-turning mounting beam 382. This structural design enables the outward-turning pusher 381 to accurately push or clamp the bag rope passing through the rope threading hole to the side of the pre-glued folding piece 96 of the bag body, ensuring smooth rope threading and gluing processes.

[0041] The outward-turning mounting beam 382 is connected to the outward-turning power source 383 through a connecting rod 384. The outward-turning power source 383 is a rotational power source. One end of the connecting rod 384 is hinged to the output end of the outward-turning power source 383, and the other end of the connecting rod 384 is hinged to the rotating shaft fixed on the outward-turning mounting beam 382.

[0042] At least one of the left and right rope-taking chucks 34 is connected to an internal driving force source 37, which drives the left and right rope-taking chucks 34 to move toward or away from each other to adjust the rope-taking position. This facilitates adjustment of the rope-taking position according to the bag size and the location of the rope-taking hole, thereby improving the versatility of the device.

[0043] The rope-pulling mechanism 32 also includes a rope-positioning member 322 for positioning one end of the rope. The other end of the rope is pulled out by a rope-pulling clamp 321, which is connected to a translational force source 323. The rope-positioning member 322 positions one end of the rope, while the rope-pulling clamp 321 pulls out the other end, ensuring the accuracy of the rope length.

[0044] The internal driving force source 37 includes left and right synchronous wheels 371 and an internal pushing belt 372 sleeved on the two synchronous wheels 371 . The left and right rope taking clamps 34 are respectively connected to different front and rear sides of the internal pushing belt 372 .

[0045] An inward push mounting seat 373 is provided below the processing platform 31 . The inward push mounting seat 373 is slidably provided on an inward push slide rail 375 via an inward push slider 374 . The chuck rotation power source 35 is installed on the inward push mounting seat 373 .

[0046] The chuck rotation power source 35 is connected to a rotating swing arm 376 that is rotatable relative to the inward push mounting seat 373 .

[0047] The left and right inner push mounting seats 373 are connected to different front and rear sides of the inner push belt 372 through clamping blocks 377 respectively.

[0048] The rope chuck 34 and rope threading mechanism 36 are separately mounted on a rotating swing arm 376, with the rope threading member 361 located below the rope chuck 34. The rope chuck 34 and the rope threading mechanism 36 can share a common power source, allowing the rope threading mechanism 36 to adjust synchronously with the adjustment of the rope chuck 34. When the rope chuck grasps the rope and rotates below the rope threading hole, the rope threading member also moves below the rope threading hole. Furthermore, if the bag size or the position of the rope threading hole changes, the internal driving force source can also synchronously adjust the rope threading member and the rope chuck.

[0049] The rope cutting device 33 is an ultrasonic cutting device. The ultrasonic cutting device can quickly and accurately cut the bag rope, and the cut is smooth, which is beneficial to the subsequent rope threading and gluing process.

[0050] The processing platform 31 is equipped with an anti-drifting component 311 that secures the bag sheet by suction or pressure. After being conveyed by the bag conveyor, the bag sheet 90 is laid flat on the processing platform 31 and secured by the anti-drifting component 311 to prevent it from shifting during processing. The anti-drifting component 311 can be a suction head or plate with a nozzle below the bag sheet, or a pressure plate or other object above the bag sheet that can hold the bag sheet in place.

[0051] The system also includes a quality inspection device 4 for inspecting the condition of the bag string on the bag body sheet 90. The quality inspection device 4 has a pass status and a fail status. A folding device 5 is also included for folding the upper edges of the bag body sheet 90 after the bag string is threaded. The quality inspection device 4 is located between the string threading device 3 and the folding device 5. The bag string condition mainly includes the presence of the string, whether it is properly attached to the bag body sheet 90, and whether the position is neat and accurate. The quality inspection device 4 can detect the position, preferably using camera vision inspection.

[0052] When the bag sheet 90 passes the inspection by the quality inspection device 4 and passes, the subsequent folding device 5 and forming device 6 operate normally. If at least one side of the bag sheet 90 fails the inspection by the quality inspection device 4, the folding device 5 on that side of the bag sheet 90 stops operating. The other side can choose to stop operating or operate normally. When the bag passes through the forming device 6, the bag can be pressed downward into a U-shape using a mold, the side sheets are folded inward, and the sides are bonded together using pressure. Alternatively, only some of these steps can be completed, or the forming process can be omitted entirely. The quality inspection device 4 is used to inspect the condition of the bag string on the bag sheet 90, allowing subsequent processing to distinguish bags that pass or fail quality inspection, facilitating the screening of bags with defective stringing. It also makes it easier for staff to distinguish and screen out open, unfolded bags. The subsequent folding work of the bags that have passed the quality inspection is eliminated, because the folding work will not only lead to the generation of waste products, but also make it impossible to distinguish between bags that have passed the quality inspection and bags that have not passed the quality inspection, thus causing trouble in screening and wasting manpower. The folding device 5 is used to fold the folding piece 96 on the outside of the bag body sheet 93 of the bag body sheet 90 inward to form an upper edge, and the forming device 6 forms the flat bag body sheet 90 into the shape of a bag using a mold and other devices. For example, the flat bag body sheet is pressed down into a U shape using a mold, and then the bag side pieces on both sides are turned inward and wrapped along the outer periphery of the mold, and then the bag side pieces on both sides are fully bonded by pressure. In this embodiment, the folding device 5 and the forming device 6 are both devices commonly used by people in this field, and their structures are not described in detail here.

[0053] As an optional embodiment, when at least one side of the bag sheet 90 is in a failed state after passing the quality inspection device 4, the side folding device 5 stops working on the bag sheet 90 and operates normally when passing through the forming device 6.

[0054] Working principle:

[0055] After the bag sheet 90 is laid flat on the processing platform 31 , the hand rope positioning member 322 of the rope pulling mechanism 32 positions one end of the hand rope, and the rope pulling clamp 321 pulls the other end of the hand rope to a preset length under the drive of the translational force source 323 .

[0056] The rope cutting device 33 pulls out the bag rope to a preset length and cuts it. The rope cutting device 33 can be a traditional knife, scissors, or hot cutter. As one possible implementation, the rope cutting device 33 is an ultrasonic cutting device, which can quickly and accurately cut the bag rope without problems such as sticking or uneven cuts. The left and right rope chucks 34 of the rope rotating mechanism first clamp the ends of the bag rope. Driven by the chuck rotation power source 35, the bag rope cut by the rope cutting device 33 is clamped and rotated to the position below the bag body sheet 90 corresponding to the bag body rope hole 97. Simultaneously, the internal driving force source 37 adjusts the position of the left and right rope chucks 34 according to the bag body size and the rope hole position. The string threading member 361 of the string threading mechanism 36 corresponds to the string threading hole 97 defined in the folding piece 96 on the outside of the bag body sheet 93 on the processing platform 31. The string threading member 361 clamps or pushes the end of the bag string through the string threading hole 97 from below the bag body sheet 90 and onto the top of the bag body sheet 90. The clamping method involves clamping the bag string from below the bag body and feeding it upward. In this method, the string threading member 361 can choose to pass through the string threading hole 97 or not, simply feeding the ends of the string on both sides to the top of the bag body sheet. The pushing method involves the string threading member 361 pushing the string below the string threading hole 97 from bottom to top. The string threading member 361 carries the string through the string threading hole 97 in a partially folded state. After passing through the string threading hole, the end of the string, due to insufficient length, naturally passes through the string threading hole 97, appearing upright or inwardly tilted.

[0057] Driven by the outward-turning power source 383, the outward-turning pusher 381 of the outward-turning mechanism 38 pushes the end of the bag string, which has passed through the string threading hole, to the side of the bag body's pre-glued flap 96. The outward-turning gluing head of the gluing device 7 pre-applies quick-drying glue to the area of the bag body flap 96 corresponding to the string threading hole 97, securing the bag string to the flap 96 and facilitating subsequent operations. The other side of the bag string can then be secured to the main bag body sheet with slow-drying reinforcement glue, ensuring greater adhesion and durability to the bag body's primary stress-bearing surface.

[0058] The quality inspection device 4 inspects the bag sheet 90 that has been threaded with the string. If the inspection passes, the quality inspection device is in the inspection pass state, and the folding device 5 and the forming device 6 operate normally. If the inspection fails, the quality inspection device is in the inspection fail state, and the folding device 5 stops working. The bag will operate normally when it passes the forming device 6. After the bag passes the folding device 5, since the bag has not been folded, it is easy to screen out bags with defective stringing. The bag threading and folding that fail the quality inspection can be manually screened out, which can save the cost of bag materials. When other bags pass the quality inspection, the folding device 5 resumes normal operation, and each bag is independently inspected and the subsequent folding operation instructions are independently performed.
