Description

Technical Field

[0001] This application relates to the technical field of data collection for packaging bags, and specifically relates to a packaging bag flipping and standing device and a two-dimensional code collection system. Background Art

[0002] Since two-dimensional codes can achieve product traceability and anti-counterfeiting effects, more and more products now print two-dimensional codes on packaging bags.

[0003] When the packaging bag is transported on the transport equipment of the production line, affected by the weight of the internal product and the structure of the transport equipment, the packaging bag usually lies horizontally on the transport equipment. When the packaging bag is in a horizontal state, the side with the two-dimensional code printed on the packaging bag will be pressed under the packaging bag, resulting in the two-dimensional code on the packaging bag not being readable and collectable by the two-dimensional code reader.

[0004] In this case, if the information collection of the two-dimensional code on the packaging bag is to be completed, only a two-dimensional code reader for the packaging bag can be installed at the position of the packaging link of the packaging bag, and the two-dimensional code on the packaging bag is collected manually. However, manual collection seriously reduces the work efficiency of the production line information system for collecting packaging, and also increases the labor intensity of the production line packaging workers.

Detailed implementation manners

[0063] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The features, structures, or characteristics described may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present invention.

[0064] When the QR code loaded on the packaging bag is transmitted on the production line, it is often pressed under the packaging bag, making the QR code data information on the packaging bag unable to be read and collected online by the QR code readers installed on the upper part or both sides. At this time, usually to complete the information collection of the packaging bag QR code, only a packaging bag QR code reader can be installed in the packaging box link, and the QR code data information of the packaging bag can be collected into the on-site industrial control computer by manual collection, and then the information is associated with the collected packaging box QR code data information. In this way, the working efficiency of the production line information system for collecting packaging is seriously reduced, and the labor intensity of the production line packaging workers is also greatly increased, which is obviously contrary to the original intention of product informatization construction.

[0065] To solve the above problems, the present application provides a packaging bag turning and standing device. Referring to Figure 1 as shown, it includes: a vertical bag baffle 200 and a rotating disk 300; the vertical bag baffle 200 is arranged at the outlet end of the packaging bag transmission device 100, and there is a distance between the vertical bag baffle 200 and the outlet end of the packaging bag transmission device 100, and the distance is greater than the first preset distance and less than the second preset distance.

[0066] The packaging bag transmission device 100 is used to transmit the packaging bag loaded with the QR code. The packaging bag transmission device 100 usually adopts the transmission mode of a conveyor belt, and can also adopt the crawler transmission mode. When the packaging bag falls from the outlet end of the packaging bag transmission device 100, the vertical bag baffle 200 will block the horizontal movement path of the packaging bag, so that the packaging bag falls vertically. Affected by gravity, the packaging bag will change its angle during the falling process and completely become an upright state.

[0067] The rotating disk 300 is arranged below the vertical bag baffle 200 and the outlet end of the packaging bag transmission device 100, and there is a gap between the rotating disk 300 and the vertical bag baffle 200. Generally, a distance of 5 mm to 10 mm can be maintained between the plane of the vertical bag baffle 200 and the rotating disk 300. The vertical bag baffle 200 and the rotating disk 300 do not rotate together, which can ensure that the position of the vertical bag baffle 200 remains fixed.

[0068] After the packaging bag falls, it will stand upright on the rotating disk 300. The rotating disk 300 rotates at a certain speed. Under the blocking action of the vertical bag baffle 200, the packaging bag will move along the edge of the rotating disk 300 and make a circular rotation movement within the ring. The rotating disk 300 will rotate to drive the packaging bag to move to the position where the QR code is collected. After the packaging bag rotates and moves half a circle on the rotating disk 300, the packaging operation is carried out to avoid excessive accumulation of packaging bags on the rotating disk 300.

[0069] The vertical bag baffle 200 is a curved plate arranged circumferentially along the rotary disk 300. The axis of the vertical bag baffle 200 passes through the center of the rotary disk 300. The difference between the radius of the rotary disk 300 and the radius of the vertical bag baffle 200 is greater than the spacing. Refer to Figure 1 , the radius of the rotary disk 300 is R, and the radius of the vertical bag baffle 200 is r. When the vertical bag baffle 200 and the rotary disk 300 are coaxial, it can be ensured that when the packaging bag rotates with the rotary disk 300, it will not bump into the vertical bag baffle 200 and cause the packaging bag to lie down again.

[0070] As can be seen from the content of the above embodiments, the packaging bag flipping and standing device provided by the present application can change the horizontal packaging bag on the packaging bag transmission device into a standing state through the vertical bag baffle 200 and fall on the rotary disk 300. After the packaging bag is flipped and stood up, the two-dimensional code originally pressed under the packaging bag is flipped to the side of the packaging bag. In this way, the two-dimensional code reader arranged on the side of the packaging bag flipping and standing device can successfully read the two-dimensional code data information on the packaging bag online, which can improve the work efficiency of the production line information system for collecting packaging and reduce the labor intensity of the production line packaging workers at the same time.

[0071] In some embodiments of the present application, continue to refer to Figure 1 shown, Figure 1 W in represents the width of the packaging bag. The first preset distance is the width of the packaging bag to be flipped, and the ratio of the second preset distance to the first preset distance is 1.5:1. That is, the spacing between the vertical bag baffle 200 and the outlet end of the packaging bag transmission device 100 is between W - 1.5W. It can also be obtained that: W < R - r < 1.5W.

[0072] When the packaging bag is output from the outlet end of the packaging bag transmission device 100, it will fall downward along the angle of the packaging bag transmission device 100. If the spacing between the vertical bag baffle 200 and the outlet end of the packaging bag transmission device 100 is less than the width of the packaging bag, the packaging bag is likely to be stuck between the vertical bag baffle 200 and the outlet end of the packaging bag transmission device 100; if the spacing between the vertical bag baffle 200 and the outlet end of the packaging bag transmission device 100 is too large, such as more than 1.5 times the width of the packaging bag, the vertical bag baffle 200 will not adjust the falling angle of the packaging bag enough, and the packaging bag will be skewed or even lie down again after falling.

[0073] In some embodiments of the present application, continue to refer to Figure 1 shown, a packaging bag two-dimensional code reader support 340 is provided outside the rotary disk 300. The packaging bag two-dimensional code reader support 340 is used to fix the packaging bag two-dimensional code reader 500; the height of the packaging bag two-dimensional code reader support 340 is between the height of the rotary disk 300 and the outlet end of the packaging bag transmission device 100, and the height of the packaging bag two-dimensional code reader support 340 is adjustable.

[0074] The packaging bag QR code reader bracket 340 is provided outside the rotating disc 300 and will not affect the rotation of the rotating disc 300. After the packaging bag QR code reader 500 is fixed on the packaging bag QR code reader bracket 340, the QR code on the packaging bag can be read. The packaging bag will rotate to the side facing the packaging bag QR code reader bracket 340 on the rotating disc 300. At the same time, since the height of the packaging bag QR code reader bracket 340 is adjustable, the packaging bag QR code reader 500 can adjust its height according to the position of the QR code on the packaging bag to ensure that the QR code can be read, making the applicable types of packaging bags more.

[0075] In some embodiments of the present application, continue to refer to Figure 1 As shown, the rotating disc 300 is horizontally arranged, and there is an inclination angle between the packaging bag conveying device 100 and the rotating disc 300; the angle range of the inclination angle is 0° - 20°, and the opening of the inclination angle faces the vertical bag baffle 200; the height of the vertical bag baffle 200 is higher than the height of the outlet end of the packaging bag conveying device 100.

[0076] The packaging bag conveying device 100 can set a small upward inclination angle θ, such as 0° ≤ θ ≤ 20°, according to the actual situation on site before reaching the packaging bag flipping and standing device. If the inclination angle is too large, the packaging bag is likely to roll off during transportation on the packaging bag conveying device 100, affecting the subsequent QR code reading. Therefore, the angle range of the inclination angle θ is controlled to be 0° - 20° so that the outlet end of the packaging bag conveying device 100 and the packaging bag flipping and standing device can be better connected.

[0077] The vertical bag baffle 200 needs to prevent the horizontal movement of the packaging bag. Therefore, it needs to be higher than the height of the outlet end of the packaging bag conveying device 100 to effectively block the packaging bag.

[0078] In some embodiments of the present application, continue to refer to Figure 1 As shown, the packaging bag flipping and standing device further includes a packaging bag dropping guide plate 110, and the packaging bag dropping guide plate 110 is fixed on the outlet end of the packaging bag conveying device 100; the packaging bag dropping guide plate 110 includes a first guide plate 111, a second guide plate 112, and a third guide plate 113; the first guide plate 111 is fixed on the outlet end of the packaging bag conveying device 100; the first guide plate 111, the second guide plate 112, and the third guide plate 113 are connected in sequence.

[0079] The packaging bag dropping guide plate 110 is composed of the folding of the first guide plate 111, the second guide plate 112, and the third guide plate 113. The width of the packaging bag dropping guide plate 110 can be equivalent to the width of the packaging bag conveying device 100 and can be fixed on both sides of the packaging bag conveying device 100 by various means such as brackets, which can avoid affecting the transportation of the packaging bag conveying device 100.

[0080] The second guide plate 112 extends towards the direction close to the vertical bag baffle 200, and the first guide plate 111 and the third guide plate 113 extend towards the direction close to the rotating disc 300; the first guide plate 111 and the third guide plate 113 are arranged perpendicular to the ground, and there is an included angle between the second guide plate 112 and the first guide plate 111. For example, the included angle can be 120° - 150°; the distance between the third guide plate 113 and the vertical bag baffle 200 is greater than the width of the packaging bag.

[0081] Refer to Figure 1 , α in the figure is the included angle, such that 120° ≤ α ≤ 150°, so as to ensure that the packaging bag will not stay when falling on the second guide plate 112 for buffering, and under the action of the inclination angle, it can easily slide onto the rotating disc 300 below, and can keep the packaging bag in a standing state.

[0082] In some embodiments of the present application, continue to refer to Figure 1 shown, the packaging bag flipping and standing device further includes a bag falling prevention guide plate 310; the vertical bag baffle 200 has a head end 210 and a tail end 220, and the packaging bag moves on the rotating disc 300 from the head end 210 to the tail end 220. Specifically, Figure 1 the "arrow" mark in

[0083] shows the rotation direction of the rotating disc 300. The rotation direction of the rotating disc 300 can be adjusted according to the actual situation at the production site, and the present application does not make specific limitations.

[0084] One end of the bag falling prevention guide plate 310 is fixedly connected to the head end 210, and the other end of the bag falling prevention guide plate 310 extends towards the edge position of the rotating disc 300 away from the vertical bag baffle 200; the bag falling prevention guide plate 310 is arc-shaped, and the bottom height of the bag falling prevention guide plate 310 is the same as the bottom height of the vertical bag baffle 200; the height of the bag falling prevention guide plate 310 is between the height h of the packaging bag and the height H of the vertical bag baffle 200.

[0085] In some embodiments of the present application, continue to refer to Figure 1As shown, the packaging bag flipping and standing device further includes a vertical bag guardrail 320; the vertical bag guardrail 320 is arranged outside the vertical bag baffle 200, and a packaging bag rotation transmission channel 230 is formed between the vertical bag guardrail 320 and the vertical bag baffle 200; the vertical bag guardrail 320 is arc-shaped, and the center of the vertical bag guardrail 320 is at the same point as the center of the vertical bag baffle 200.

[0086] The diameter of the vertical bag guardrail 320 is the same as that of the rotating disk 300, and the length of the vertical bag guardrail 320 is 1 / 4 to 1 / 3 of the outer edge length of the rotating disk 300. If the vertical bag guardrail 320 is too short, such as less than 1 / 4 of the outer edge length of the rotating disk 300, the achieved protection effect is weak, and the packaging bag is easily touched; if the vertical bag guardrail 320 is too long, such as greater than 1 / 3 of the outer edge length of the rotating disk 300, it will affect the staff to take the packaging bag from the rotating disk 300 for boxing.

[0087] The distance between the vertical bag guardrail 320 and the rotating disk 300 is 5mm - 10mm. A certain gap needs to be reserved between the vertical bag guardrail 320 and the rotating disk 300 to prevent the vertical bag guardrail 320 from touching the rotating disk 300 and affecting the rotation of the rotating disk 300. Since there is a certain tolerance range for the manufacturing and installation dimensions of the rotating disk 300, the gap should be at least greater than 5mm, and the gap should not exceed 10mm. If the gap is too large, there will be a situation where the packaging bag gets stuck in the gap. And the vertical bag guardrail 320 is arranged on one side close to the outlet end of the packaging bag transmission device 100 and is located outside the vertical bag baffle 200. The vertical bag guardrail 320 is arc-shaped, and the downward projection of its inner arc line can overlap with the outer arc line of the rotating disk 300.

[0088] In some embodiments of the present application, it further includes a guardrail fixing frame 330; the guardrail fixing frame 330 is arranged outside the rotating disk 300 and fixed on the ground; the guardrail fixing frame 330 is fixedly connected to the vertical bag guardrail 320 and jointly forms the packaging bag rotation transmission channel 230 with the vertical bag guardrail 320 and the vertical bag baffle 200. The vertical bag guardrail fixing frame 330 is used to fix the vertical bag guardrail 320 to ensure that the vertical bag guardrail 320 and the vertical bag baffle 200 together form the packaging bag rotation transmission channel 230, so that the packaging bag makes a circular rotation movement along with the rotating disk within the packaging bag rotation transmission channel 230 in the edge ring.

[0089] In some embodiments of the present application, continue to refer to Figure 1 As shown, the packaging bag flipping and standing device further includes a support assembly 400, and the support assembly 400 includes: a support column 410, a support beam 420, a support beam handle 430, and a fixing piece 440.

[0090] Support columns 410 are provided on both sides of the outlet end of the packaging bag conveying device 100, and one end of the support columns 410 is fixed to the ground. The support columns 410 are fixed to the ground on both sides of the packaging bag conveying device 100 and are used to support the support beam 420, the support beam handle 430, the fixing piece 440, the vertical bag baffle 200, etc. The position of the support columns 410 can be adjusted according to the layout of the on-site equipment, such as being fixed on one side of the rotating disc 300, and the present application does not make specific restrictions.

[0091] Threaded holes are provided at the other end of the support columns 410. The surface of the support beam 420 has threads. The support beam 420 passes through the threaded holes on the support columns 410 and is threadedly connected to the support columns 410. One end of the support beam 420 close to the vertical bag baffle 200 has a fixing piece 440. One end of the support beam 420 is connected to the fixing piece 440. One end of the fixing piece 440 is fixedly connected to the support beam 420, and the other end is fixedly connected to the vertical bag baffle 200; it is used to hang and fix the vertical bag baffle 200 so that the vertical bag baffle 200 can stably block the packaging bag on the outer ring of the rotating disc 300 for rotation.

[0092] The balance point position near the center of the support beam 420 is installed on the support column 410, which can play a role in supporting the vertical bag baffle 200. The support beam 420 has a rotating screw that passes through the support column 410. One end of the support beam 420 far from the vertical bag baffle 200 has a support beam handle 430. The support beam handle 430 is fixedly connected to the support beam 420, and the relative position of the vertical bag baffle 200 on the rotating disc 300 can be adjusted through the support beam handle 430.

[0093] The baffle support beam handle 430 can be adjusted by manually rotating the handle. For example, when the width W of the packaging bag changes, the baffle support beam handle 430 can change the width of the packaging bag rotation transmission channel 230 between the vertical bag baffle 200 and the vertical bag guardrail 300 by adjusting the position of the vertical bag baffle 200, so that the vertical packaging bag can rotate and be conveyed more smoothly on the edge ring channel of the rotating disc 300.

[0094] As can be seen from the above embodiments, the packaging bag flipping and standing device provided by the present application changes the horizontal packaging bag on the packaging bag conveying device into a standing one through the standing bag baffle 200. After the packaging bag becomes standing, it falls on the rotating disc 300. The two-dimensional code that was originally pressed under the lower part of the packaging bag is flipped to the side of the packaging bag after the packaging bag flips and stands. In this way, the two-dimensional code reader installed on the side of the packaging bag flipping and standing device can successfully read the two-dimensional code data information on the packaging bag online; at the same time, through the anti-bag-drop guiding plate 310, the unpacked packaging bags can be rotated to the packing position again to avoid repeated reading of the two-dimensional code on the packaging bag; the stability of the device is improved through structures such as the guardrail fixing frame 330, the guardrail fixing frame 330, and the support assembly 400 to ensure accurate reading of the two-dimensional code on the packaging bag without confusion. The packaging bag flipping and standing device provided by the present application can improve the working efficiency of the production line information system for collecting packages, and at the same time reduce the labor intensity of the production line packaging workers.

[0095] Based on the packaging bag flipping and standing device shown in the foregoing embodiments, the present application further provides a two-dimensional code collection system. Referring to Figure 2 as shown, the two-dimensional code collection system includes: a packaging bag two-dimensional code reader 500, which is fixed outside the rotating disc 300 of any one of the packaging bag flipping and standing devices in the above embodiments. The packaging bag two-dimensional code reader 500 is used to read the two-dimensional code on the packaging bag; the packaging bag two-dimensional code reader 500 is installed on one side of the standing bag guardrail 200, and its reading light is vertically directed at the position of the two-dimensional code on the side of the passing packaging bag. When the packaging bag two-dimensional code reader 500 receives the collection signal instruction sent by the on-site industrial control computer, it reads and collects the two-dimensional code data information on the packaging bag, and sends the collected information to the on-site industrial control computer for further information processing.

[0096] In some embodiments of the present application, the two-dimensional code collection system includes a packing box two-dimensional code reader 600 fixed on one side of the packaging bag packing production line 120. The packing box two-dimensional code reader 600 is used to read the two-dimensional code on the packing box. Among them, the packing box is used to hold the packaging bag. When the packing quantity of the packaging bag reaches the set full box quantity, manual sealing or automatic sealing is performed. The packing quantity of the packaging bag can be specified according to the actual situation. The packing box two-dimensional code reader 600 is installed on one side of the packaging bag packing production line 120, and its reading light is vertically directed at the position of the two-dimensional code on the side of the packing box. The packing box two-dimensional code is loaded on the side of the packing box, corresponding to the position of the packing box two-dimensional code reader 600. When the packing box two-dimensional code reader 600 receives the collection signal instruction sent by the on-site industrial control computer, it reads and collects the two-dimensional code data information on the packing box, and sends the collected information to the on-site industrial control computer for further information processing.

[0097] The packing box QR code reader 600 can be installed through the packing box reader mounting bracket 620. The packing box reader mounting bracket 620 is fixed to the side of the packing bag packing production line. The installation height of the packing box reader mounting bracket 620 can make the packing box QR code reader 600 at the same height as the QR code on the packing box, so that the reading light of the reader is perpendicular to the QR code identification plane on the packing box.

[0098] The packing bag packing production line 120 is connected to the end of the rotating disc 300 and is used to place and convey the packing box. When the packing bag rotates with the rotating disc 300 to the packing position of the packing bag packing production line 120, the packing bags that have been read and collected by the packing bag QR code reader 500 are loaded into the packing box according to the specified packing quantity manually (or by an automatic packing device). When the packing box is full of packing bags, the packing bag packing production line 120 conveys the packing box to the next link. Or the packing box is loaded into the pallet 130 according to the specified quantity, or the packing box is directly stored in the warehouse for management, and when needed, the pallet 130 or the packing box is taken out of the warehouse and enters the logistics and sales links.

[0099] In some embodiments of the present application, the QR code acquisition system further includes a pallet QR code reader 700 fixed to one side of the pallet 130. The pallet QR code reader 700 is used to read the QR code on the pallet 130. Among them, the pallet 130 is used to hold the packing box. When the packing quantity of the packing box reaches the set full box quantity, the pallet 130 finishes packing. The packing quantity of the packing box can also be specified according to the actual situation. The pallet QR code is loaded on the side of the pallet 130 and corresponds to the position of the pallet QR code reader 700. During the process of loading the packing box into the pallet 130, the pallet QR code reader 700 can read and collect the data information thereon.

[0100] The pallet QR code reader 700 is installed at the end of the packing bag packing production line 120, and its reading light is vertically facing the QR code position on the side of the pallet 130. When the pallet QR code reader 700 receives the acquisition signal instruction sent by the on-site industrial computer, it reads and collects the QR code data information on the pallet 130 and sends the collected information to the on-site industrial computer for further information processing.

[0101] In some embodiments of the present application, the QR code acquisition system further includes an industrial computer that is sequentially communicatively connected to the packing bag QR code reader 500, the packing box QR code reader 600, and the pallet QR code reader 700. The industrial computer is configured to send instructions for reading the QR code data information to the packing bag QR code reader 500, the packing box QR code reader 600, and the pallet QR code reader 700.

[0102] In some embodiments of the present application, continue to refer to Figure 2As shown, it further includes: a packaging bag detection photoelectric switch 510, a packing box detection photoelectric switch 610, and a pallet detection photoelectric switch 710; the packaging bag detection photoelectric switch 510, the packing box detection photoelectric switch 610, and the pallet detection photoelectric switch 710 are sequentially communicatively connected to the industrial control computer.

[0103] The packaging bag detection photoelectric switch 510 is fixed on the side of the packaging bag two-dimensional code reader 500 close to the packaging bag transmission device 100. The packaging bag detection photoelectric switch 510 is used to obtain the passing signal of the packaging bag and send the passing signal of the packaging bag to the industrial control computer. The packaging bag detection photoelectric switch 510 is installed on one side of the vertical bag guardrail 200 for detecting the passing signal of the package. When the packaging bag passes through the position of the packaging bag detection photoelectric switch 510, the packaging bag detection photoelectric switch 510 sends the passing signal of the packaging bag to the on-site industrial control computer, and the industrial control computer sends an instruction to read the data information of the two-dimensional code on the packaging bag to the packaging bag two-dimensional code reader 500 according to the passing signal of the packaging bag, so as to read and collect the data information of the two-dimensional code on the packaging bag.

[0104] The packing box detection photoelectric switch 610 is fixed on the side of the packing box two-dimensional code reader 600 close to the packaging bag packing area. The packing box detection photoelectric switch 610 is used to obtain the passing signal of the packing box and send the passing signal of the packing box to the industrial control computer. During the period when the packaging bag is loaded into the packing box, the packing box detection photoelectric switch 610 detects the signal of the existence of the packing box and transmits the detection signal to the on-site industrial control computer. The industrial control computer sends an instruction to read the data information of the two-dimensional code on the packing box to the packing box two-dimensional code reader 600 according to the passing signal of the packing box, so as to read the data information of the two-dimensional code on the packing box.

[0105] The pallet detection photoelectric switch 710 is fixed on the side of the pallet two-dimensional code reader 700 close to the packing box palletizing area. The pallet detection photoelectric switch 710 is used to obtain the passing signal of the pallet 130 and send the passing signal of the pallet 130 to the industrial control computer. During the period when the packing box is loaded into the pallet 130, the pallet detection photoelectric switch 710 detects the signal of the existence of the pallet 130 and transmits the detection signal to the on-site industrial control computer. The industrial control computer sends an instruction to read the data information of the two-dimensional code on the pallet to the pallet two-dimensional code reader 700 according to the passing signal of the pallet, so as to read the data information of the two-dimensional code on the pallet.

[0106] In some embodiments of the present application, the packaging bag two-dimensional code reader 500 is configured to: receive an instruction to read the two-dimensional code data information of the packaging bag, read the two-dimensional code data information of the packaging bag, and send the two-dimensional code data information of the packaging bag to the industrial control computer; the packaging box two-dimensional code reader 600 is configured to: receive an instruction to read the two-dimensional code data information of the packaging box, read the two-dimensional code data information of the packaging box, and send the two-dimensional code data information of the packaging box to the industrial control computer; the pallet two-dimensional code reader 700 is configured to: receive an instruction to read the two-dimensional code data information of the pallet, read the two-dimensional code data information of the pallet, and send the two-dimensional code data information of the pallet to the industrial control computer; the industrial control computer is further configured to: receive the two-dimensional code data information of the packaging bag, the two-dimensional code data information of the packaging box, and the two-dimensional code data information of the pallet, and perform processing and storage.

[0107] The working process of the packaging bag flipping and standing device and the two-dimensional code acquisition system in the above embodiments is as follows:

[0108] The packaging bag loaded with the two-dimensional code is horizontally transported on the packaging bag transmission device. The side of the two-dimensional code on the packaging bag is in contact with the upper surface of the conveyor belt of the packaging bag transmission device, and the packaging bag is transported towards the outlet end of the transmission device.

[0109] When the packaging bag runs to the outlet end of the packaging bag transmission device, it falls downward along the packaging bag dropping guide plate. After being buffered by the second guide plate, it falls on the rotating disc between the third guide plate and the outer arc surface of the standing bag baffle.

[0110] After the packaging bag stands and falls on the rotating disc, the two-dimensional code on its side faces towards the outside of the rotating disc. Driven by the rotating disc, the packaging bag rotates along with the outer ring of the rotating disc.

[0111] When the packaging bag rotates past the packaging bag two-dimensional code reader on one side of the standing bag protection fence, the packaging bag detection photoelectric switch detects the passing of the packaging bag, and the passing signal of the packaging bag is sent to the industrial control computer. The industrial control computer then issues an instruction to read the two-dimensional code data information of the packaging bag to the packaging bag two-dimensional code reader. The two-dimensional code reader then identifies and collects the two-dimensional code data information on the packaging bag, and sends the collected information to the on-site industrial control computer for information processing.

[0112] The packaging bag continues to rotate and run with the rotating disc. When it runs from the falling point to the semi-circular arc and reaches the packing production line on the opposite side of the rotating disc, it is packed manually or automatically. During the process of packing the packaging bag into the packaging box, the packaging box detection photoelectric switch detects the passing signal of the packaging box, and sends the passing signal of the packaging box to the industrial control computer. The industrial control computer then issues an instruction to read the two-dimensional code data information of the packaging box to the packaging box two-dimensional code reader. The packaging box two-dimensional code reader then identifies and collects the two-dimensional code data information on the packaging box, and sends the collected information to the on-site industrial control computer for information processing.

[0113] During manual packing, if the packaging bag fails to be packed in time, the packaging bag will continue to rotate on the rotating disc. After reaching the anti-bag-falling guide plate, the packaging bag will be guided to run inside the arc of the vertical bag baffle until it reaches the packing production line again for repacking. However, it needs to be packed into the original packing box according to the original scanning code sequence to ensure the accuracy of the corresponding QR code data information between the packaging bag and the packing box.

[0114] When the packaging bag QR code reader collects the data information of the packaging bags up to the full box quantity m, the industrial control computer will form a set of corresponding relationships between the data information of one packing box and the data information of m packaging bags. That is: after the packaging bags fill the box, the industrial control computer automatically realizes the 1:m corresponding relationship between the data of the packing box and the packaging bags.

[0115] After the packing box is sealed, it can be directly taken offline and stored in the warehouse or continue to run to the palletizing section. During the process of putting the packaging bag boxes onto the pallet, when the pallet detection photoelectric switch detects the passing signal of the pallet, it will send the passing signal of the pallet to the industrial control computer. The industrial control computer will then send an instruction to read the QR code data information of the pallet to the pallet QR code reader. The pallet QR code reader will identify and collect the QR code data information on the pallet and send the collected information to the on-site industrial control computer for information processing.

[0116] When the packing box QR code reader collects the data information of the packing boxes up to the full pallet quantity n, the industrial control computer will form a set of corresponding relationships between the data information of one pallet and the data information of n packing boxes. That is: after the packing boxes fill the pallet, the industrial control computer automatically realizes the 1:n corresponding relationship between the data of the pallet and the packing boxes.

[0117] The two-level data correspondence between the packing box and the packaging bag, as well as the three-level data correspondence among the packaging bag, the packing box and the pallet, are automatically realized on the production line. The packed boxes or pallets are taken offline and directly stored in the warehouse, waiting for sales and shipment.

[0118] As can be seen from the working process of the above-mentioned packaging bag turning and standing device and the QR code acquisition system, after the packaging bag is changed from a horizontal position to a vertical position by the packaging bag turning and standing device in this application, the QR code on the packaging bag can be read and acquired by the QR code reader. Further, the QR code acquisition system reads and acquires the QR codes on the packaging bag, the packing box, and the pallet, realizing the three-level data correspondence among the packaging bag, the packing box, and the pallet. After the product is sold and shipped out of the warehouse, taking the QR code data information of the packing box as the tracking and tracing source, through the distribution link and the sales link, the data information tracking and data source tracing of the first level of the packing box can be realized through the QR code acquisition system. After the product is sold to the consumer, the consumer can, according to the QR code data information on the packaging bag and through the corresponding relationship between the QR code system and the packaging bag and the packing box, realize the data information tracking and data source tracing of the first level of the packaging bag.

[0119] As can be seen from the content of the above-mentioned embodiment, on the one hand, this application provides a packaging bag turning and standing device, which can make the QR code originally pressed under the packaging bag turn to the side of the packaging bag after the packaging bag turns and stands. In this way, the QR code reader arranged on the side of the packaging bag turning and standing device can successfully read the QR code data information on the packaging bag online, which can improve the working efficiency of the production line information system for collecting packaging and at the same time reduce the labor intensity of the production line packaging workers. On the other hand, a QR code acquisition system is provided. After the product is sold and shipped out of the warehouse, taking the QR code data information of the packing box as the tracking and tracing source, through the distribution link and the sales link, the data information tracking and data source tracing of the first level of the packing box and the packaging bag can be realized through the QR code acquisition system. The data informatization management of the product is realized.
