Description

Technical Field

[0001] The invention relates to packaging material processing equipment, in particular to a woven bag inner and outer bag covering and upper opening bonding device. Background Art

[0002] Cylindrical packaging materials are packaging materials processed into a cylindrical shape. This type of packaging material can be made of plastic, paper, fabric, rubber and other materials. When used, a section is cut according to the length required (one end is sealed to make a packaging bag). When packaging, only the two ends need to be sealed to complete the sealing of the entire bag, which greatly saves the processing procedures. In recent years, the usage has continued to grow. In order to improve the protective effect of this type of packaging material, the cylindrical packaging material is divided into an inner and outer layer, that is, a double-layer cylindrical packaging material. When the inner or outer layer is damaged, there is another layer that still plays a protective role. At present, a single strip is cut, and the outer bag and the inner bag are sealed separately. The bottom is put together, and then the upper mouths of the inner and outer bags are sealed together and the whole is opened. At present, it is mainly sealed with a sewing machine, or bonded with adhesives, etc., which requires manual operation. Not only is the efficiency very low, but it is also very physically demanding.

[0033] like Figure 1-14 As shown, a woven bag inner and outer bag bagging and upper bonding device comprises a bagging support device 1 and a glue spraying device 2. The bagging support device 1 is driven to move by a moving device so that the bagging support device 1 moves relative to the glue spraying device 2. The inner film bag and the cylindrical woven bag are respectively put on the bagging support device 1 in sequence, and after the inner film bag is put on, the bagging support device 1 or the glue spraying device 2 is moved to spray the outer side surface of the inner film bag stretched on the bagging support device 1 with adhesive. After the cylindrical woven bag is put into, the cylindrical woven bag and the inner film bag are bonded with the sprayed adhesive.

[0034] Specifically: there are two groups of bagging support devices 1, and the two groups of bagging support devices 1 are driven to move by the mobile device at the same time. The inner film bag corresponds to the starting position of the bagging support device 1, and the inner film bag is loaded by the bag making machine 3. A cylindrical packaging material cutting knife is arranged between the bagging support device 1 and the bag making machine 3. The cutting knife can adopt the existing technology as long as it can achieve cutting. For example, the cutting knife is supported by the gantry and driven by the lead screw and the servo motor. It can adopt sliding cutting method, other cutting methods and manual cutting, etc. The cylindrical woven bag corresponds to the next workstation of the bagging support device 1, that is, after the inner film bag is put on, it moves to the next workstation, and the cylindrical woven bag is loaded with an outer bag bin device 4 with multiple bins.

[0035] The bagging support device 1, the bag making machine 3, and the outer bag bin device 4 are arranged horizontally. The starting position of the bagging support device 1 and the next workstation at each location are respectively provided with a bag-holding and bagging device 5 for putting an inner film bag or a cylindrical woven bag on the bagging support device 1. The outer bag bin device 4 or the bag making machine 3 is also provided with a bag grabbing and conveying device 6 for grabbing the inner film bag or the cylindrical woven bag on the outer bag bin device 4 and the bag making machine 3 and sending it to the bag-holding and bagging device 5. A finished product receiving bin 7 is also provided on the outer side of the outer bag bin device 4 at the cylindrical woven bag. The finished product receiving bin 7 is provided with a material unloading clamping device 8 for clamping and removing the finished product. The bagging support device 1 is fixed to one side of a sliding block 10 of a linear guide rail 9. The sliding block 10 is driven by a chain drive or a synchronous belt structure and moves back and forth along the linear guide rail 9. The screw structure or the chain drive structure is a prior art, and it is sufficient as long as the sliding block 10 can move back and forth along the linear guide rail 9.

[0036] The bagging support device 1 has two forms, one of which is a rod-shaped structure, including a fixed connection frame 101 and a support frame 102 composed of thin rods, the fixed connection frame 101 is fixedly connected to the sliding block 10, and an end support frame 103 is provided at one end of the support frame 102 close to the outer bag bin device 4 or the bag making machine 3, and the other end of the support frame 102 is respectively fixed with outwardly telescopic side support cylinders 104 on both sides, and side support rods 105 are respectively provided on both sides of the support frame 102, one end of each side support rod 105 is fixedly connected to the support frame 102 through a rotating hinge 106, and the other end of each side support rod 105 is fixedly connected to the telescopic end of each side support cylinder 104 through a rotating hinge 106, so that the side support cylinder 104 pushes the side support rod 105 to swing to both sides or merge inward, and the end support frame 103 slides with the support frame 102 through two guide rods 107 that penetrate the support frame. An end telescopic cylinder 108 is fixed in the connection and fixed connection frame 101, and a connecting push rod 109 that penetrates the central body of the support frame 102 is fixed at the telescopic end of the end telescopic cylinder 108. The connecting push rod 109 is fixedly connected to the cross bar between the two guide rods 107 in the support frame 102, so that the end telescopic cylinder 108 pushes the end support frame 103 to move outward to expand or retract. The expansion and retraction of this bagging support device 1 can be achieved by controlling the expansion and contraction of the side support cylinder 104 and the end telescopic cylinder 108. When the side support cylinder 104 and the end telescopic cylinder 108 are extended at the same time, the bagging support device 1 is expanded (it is convenient to expand and tighten the opening glue application part of the tubular packaging material, and make the surface flat after expansion, which is convenient for uniform glue application). Conversely, when the side support cylinder 104 and the end telescopic cylinder 108 are contracted at the same time, the bagging support device 1 is retracted (that is, it is contracted to be smaller, which is convenient for bagging and bag removal).

[0037] In addition, the bag support device 1 can also adopt a frame structure, including a main body fixed tube 110 and an end cross bar 111 located at one end of the main body fixed tube 110, an end support column 112 close to the outer bag bin device 4 or the bag making machine 3 is arranged on the outside of the end cross bar 111, and the middle part of the end support column 112 is fixedly connected with the telescopic end of the end tightening cylinder 115 in the fixed end of the main body fixed tube 110 through a connecting push rod 109 that passes through the main body fixed tube 110, and the end support columns 112 on both sides of the connecting push rod 109 are respectively fixed with guide columns 113 that pass through the end cross bar 111, and both ends of the end cross bar 111 The side support rods 117 are rotatably fixed by the movable hinges 116, so that the middle parts of the inner sides of the side support rods 117 are rotatably connected with the shafts on the main body fixing tube 110 and the connecting push rod 109 through the T-shaped cross rods 118, and the shaft of the connecting push rod 109 is located in the long strip slide groove 119 on one side of the main body fixing tube 110, and the shaft at the other end of the cross rod 118 is located in the side support rod 117. The expansion or retraction of the bag support device 1 is mainly achieved by controlling the extension and contraction of the end tightening cylinder 115. When the end tightening cylinder 115 is extended, the connecting push rod 109 is pushed to move upward (such as Figure 5 ), so that the cross rod 118 is compressed, such as the current umbrella frame structure, so that the cross rod 118 is relatively extended, and the side support rod 117 is pushed outward to form an opening action. At the same time, the connecting push rod 109 moves upward and then pushes the end support column 112 to move upward, and at the same time, the end support column 112 is opened, and finally the opening of the bagging support device 1 is realized (it is convenient to open and tighten the opening glue application part of the tubular packaging material, and make the surface flat after opening, which is convenient for uniform glue application). Conversely, when the end tightening cylinder 115 contracts, it drives the side support rod 117 and the end support column 112 to move inward at the same time, thereby realizing the retraction of the bagging support device 1 (that is, it shrinks and becomes smaller, which is convenient for bagging and taking out bags).

[0038] The outer side surfaces of the end support frame 103 and the end support column 112 are respectively provided with symmetrical clamping notches 121. The cylindrical woven bag is put on and cut to fit with the inner film bag and then processed into a finished product. The finished product is taken down by the unloading clamping device 8. The clamping device of the unloading clamping device 8 just corresponds to the edge of the finished product at the clamping notch 121 to prevent the bagging support device 1 from being clamped, thereby facilitating unloading.

[0039] The outer side distance of the swinging ends of the two side support rods 105 and the side support rod 117 is greater than the spacing between the rotating fixed ends, so that the bagging support device 1 forms an isosceles trapezoidal structure with a narrower upper base than the lower base, which is not only convenient for inserting cylindrical packaging materials, but also convenient for removing finished products when unloading.

[0040] Each guide column 113 is respectively provided with a rebound spring 122, and the connecting push rod 109 is elastically connected to the cross bar through the rebound spring 122. The rebound spring 122 supports the rebound of the end support frame 103 and the end support column 112. The telescopic end of the side support cylinder 104 is provided with a buffer spring 123. The buffer spring 123 plays a buffering role to prevent excessive opening force on the cylindrical packaging material during opening, thereby damaging the cylindrical packaging material. A support frame plate 114 fixedly connected to both sides of the main fixed cylinder 110 is provided between the swinging ends of the side support rods 117. The support frame plate 114 corresponds to the gluing position. After the cylindrical woven bag is inserted, in order to make the inner film bag and the cylindrical woven bag fit firmly, the bag-holding and bag-covering device 5 compacts the support frame plate 114, so that the inner film bag and the cylindrical woven bag are further fitted through compaction.

[0041] Air holes 120 are respectively arranged in the surfaces of one end of the support frame plate 114 and the two support frames 102. The air holes 120 on the same surface are interconnected and finally connected to an external vacuum device or an air pumping device through a hose. The function of the air holes 120 can be to absorb air. For example, after the inner membrane bag is put into place, the inner membrane bag can be adsorbed to make it smoother. In addition, air can also be blown after the cylindrical woven bag is put into place. This can allow the inner membrane bag to be bonded to the cylindrical woven bag through the sprayed glue, thereby playing a good auxiliary role.

[0042] The glue spraying device 2 is symmetrically arranged up and down, and consists of a nozzle 201 and a nozzle fixing frame 202. The nozzle 201 is vertically fixed at one end of the nozzle fixing frame 202, and the spraying end of the nozzle 201 is perpendicular to the main surface of the bagging support device 1 passing through. A central glue spraying hole 203 connected to an external glue spraying device is arranged at the center of the spraying end of the nozzle 201. Blowing holes 204 that are interconnected are evenly arranged around the central glue spraying hole 203. The blowing holes 204 are connected to an external air supply device and are used to spray outward around the central glue spraying hole 203. They are mainly used for spraying pressure-sensitive adhesives. During the glue spraying process, the blowing holes 204 around the central glue spraying hole 203 are used to spray air, and the blowing holes 204 can be arranged obliquely around the center of the central glue spraying hole 203, so that the wind blown out by the blowing holes 204 can also form a spiral shape, thereby improving the glue spraying effect and making the glue more uniform.

[0043] The outer bag bin device 4 includes more than two outer bag bins 401. The outer bag bin 401 and the packaging bag placement platform 402 of the outer bag bin 401 are driven to rise and fall by a screw and a servo motor. The packaging bag placement platform 402 places a certain number of tubular packaging materials (inner layer or tubular woven bag, placed as needed) of a certain height. A photoelectric sensor 403 for sensing the material is fixed on the inner wall of the outer bag bin 401 above the packaging bag placement platform 402. The photoelectric sensor 403 is mainly used to sense the height of the material so that the upper surface of the packaging bag is always at the grabbing height. As the use of the packaging bag gradually decreases, the packaging bag placement platform 402 gradually rises, which is the currently commonly used packaging bag feeding structure, which belongs to the prior art and will not be repeated here. A bag grabbing and conveying device 6 for grabbing the packaging bag is arranged above the outer bag bin 401. The bag grabbing and conveying device 6 is driven by a screw and a servo motor to move horizontally at the top of the outer bag bin 401. The outer bag bin 401 is driven by a driving device to move along the slide rail laid at the bottom. It can move left and right and can also be adjusted as needed. The position of the outer bag bin 401 moves in the forward and backward directions. A top baffle 404 is fixed on the top of the outer bag bin 401. The top baffle 404 is used to support the finished product grasped by the unloading clamping device 8 to pass through, so as to prevent the unloading clamping device 8 from hitting the packaging bag on the packaging bag placement platform 402 when grasping the finished product. The bag grabbing conveying device 6 includes a bag grabbing cylinder 601 that can move horizontally on the top of the outer bag bin device 4 and a bag grabbing suction cup 602 driven to rise and fall by the bag grabbing cylinder 601. The bag grabbing suction cup 602 is long and is in the corresponding bag supporting and bagging device 5. A raised structure 603 is respectively provided on one side edge, the bag grabbing suction cup 602 is hollow inside, and the suction cup suction hole for sucking the bag is located on the lower surface of the bag grabbing suction cup 602 and the raised structure 603. The upper end of the bag grabbing cylinder 601 is driven to move horizontally back and forth by one of the guide rails, mechanical arms, screw structures or synchronous belts above the outer bag warehouse device. The bag grabbing suction cup 602 is used to suck up the inner film bag and the tubular woven bag on the packaging bag placement platform 402 for grabbing, and then send them to the bag supporting and bagging device 5 to facilitate the next step of bagging.

[0044] The bag-supporting and bag-covering device 5 includes an upper bag-sucking plate 501 and a lower bag-sucking plate 502 which are driven to rise and fall by a cylinder. The upper bag-sucking plate 501 and the lower bag-sucking plate 502 are fixed in a movable frame 503 by a cylinder. The cross-section of the movable frame 503 is in the shape of a square. The upper bag-sucking plate 501 and the lower bag-sucking plate 502 are hollow structures. The upper bag-sucking plate 501 and the lower bag-sucking plate 502 are opposite to each other. The opposite sides are both provided with a suction port 504 which is connected to the upper bag-sucking plate 501 and the lower bag-sucking plate 502. The hollow cavities of the upper bag-sucking plate 501 and the lower bag-sucking plate 502 are connected to an external suction device through a hose on one side, so that the upper bag-sucking plate 501 and the lower bag-sucking plate 502 form a longer suction cup structure. The bottom of both sides of the moving frame 503 are supported on the slide rails on both sides of the bag support device 1, so that the bag support device 1 is located between the planes where the upper bag suction plate 501 and the lower bag suction plate 502 are located, and the moving frame 503 is driven by a driving device to move back and forth along the slide rails through the bag support device 1, and an inwardly recessed U-shaped notch 505 is provided on the edge of the side opposite to the bag grabbing suction cup 602, and the U-shaped notch 505 corresponds to the raised structure 603 of the bag grabbing suction cup 602, so that when the upper bag suction plate 501 contacts the bag grabbing suction cup 602, the U-shaped notch 505 and the raised structure 603 are meshed, and the U-shaped notch 505 and the raised structure The cooperation with the structure 603 can reduce the time for the inner film bag and the cylindrical woven bag to be sent to the bag supporting and bagging device 5, and when the bag grabbing suction cup 602 contacts the upper bag suction plate 501, the U-shaped notch 505 and the convex structure 603 are crossed together, which can ensure that the inner film bag and the cylindrical woven bag are sent more accurately and adsorbed more firmly. After the inner film bag and the cylindrical woven bag (the inner film bag and the cylindrical woven bag are also called cylindrical packaging materials) are sent by the bag grabbing conveying device 6, the upper bag suction plate 501 and the lower bag suction plate 502 are driven by the cylinder to clamp the upper and lower surfaces of the opening of the inner film bag and the cylindrical woven bag respectively, and the interior of the upper bag suction plate 501 and the lower bag suction plate 502 are evacuated, so that the upper bag suction plate 501 and the lower bag suction plate 502 are The suction port 504 of the plate 502 generates negative pressure, so that the upper and lower surfaces of the opening of the inner film bag and the cylindrical woven bag are sucked by the upper and lower suction bag plates 501 and the lower suction bag plates 502. Then, the upper and lower suction bag plates 501 and the lower suction bag plates 502 are driven upward and downward respectively by the cylinder. Since the upper and lower suction bag plates 501 and the lower suction bag plates 502 respectively suck the upper and lower surfaces of the opening of the inner film bag and the cylindrical woven bag, the upper and lower suction bag plates 501 and the lower suction bag plates 502 move outward at the same time to open the openings of the inner film bag and the cylindrical woven bag. Then, the moving frame 503 is driven to move by the driving device. During the horizontal movement of the moving frame 503, the inner film bag or the cylindrical woven bag is put on the bagging support device 1, as shown in FIG. Fig. 9 In order to better receive the tubular packaging material sent by the bag grabbing conveyor 6, the length of the lower bag suction plate 502 is greater than that of the upper bag suction plate 501. Fig.11Even if the opening of the tubular packaging material sags after it is delivered, the opening of the tubular packaging material will be located on the surface of the lower suction bag plate 502, making it easier for the upper suction bag plate 501 and the lower suction bag plate 502 to move further into position for suction bagging.

[0045] The bag grabbing sucker 602 may also be a single circular sucker, each sucker corresponding to a U-shaped notch 505 of the upper bag suction plate 501, and each bag grabbing sucker 602 is driven to rise and fall by a single cylinder, such as Fig.11 At this time, when delivering the inner film bag or the tubular woven bag, each bag grabbing suction cup 602 can be located in the U-shaped notch 505.

[0046] In addition, as the inner film bag is relatively thin, a special inner film bag support and bagging device can be used for the inner film bag. The movable frame 503 is divided into two parts, upper and lower, and is supported on four slide rails, namely, the top slide rail and the bottom slide rail (such as Fig.13 ), wherein the lower part is similar to a U-shaped structure, the upper part is plate-shaped, and the other structures are the same as the above-mentioned bag holding and bagging device 5, so that the bagging support device 1 can move horizontally between the upper bag suction plate 501 and the lower bag suction plate 502, and the bagging support device 1 can return to its position without waiting for the upper bag suction plate 501 and the lower bag suction plate 502 to return to their positions, thereby saving processing time.

[0047] In order to facilitate the grasping of the thinner inner film bag, the bag grasping suction cup 602 is a horizontal plate-like structure (such as Fig.14 ), the bag making machine 3 places the cut inner film bag on the bag grabbing suction cup 602, and the edge of the bag grabbing suction cup 602 is provided with a U-shaped notch 505, and the U-shaped notch 505 is provided with a suction port 504. At this time, the upper bag suction plate 501 and the lower bag suction plate 502 are plate-like structures, and the lower bag suction plate 502 is provided with a protruding structure 603 corresponding to the U-shaped notch 505 (such as Fig.14 ), when delivering the inner membrane bag and the tubular woven bag, each bag grabbing suction cup 602 can be located in the U-shaped notch 505, which is convenient for delivering the thinner inner membrane bag and stretching it to be sleeved on the bag supporting device 1. This structure is mainly used for the inner membrane bag.

[0048] The material unloading clamping device 8 includes a symmetrically arranged telescopic grabbing cylinder 801 and a clamp 802. A small clamping cylinder 804 is arranged at one end of the clamp 802. The small clamping cylinder 804 is used to drive the clamp 802 to clamp and open and close. The clamp 802 is perpendicular to the plane where the main body of the bagging support device 1 is located. The small clamping cylinder 804 is extended to make the clamp 802 clamp the finished product on the bagging support device 1, and then the telescopic grabbing cylinder 801 is retracted, and the finished product is placed in the finished product receiving bin 7. The small clamping cylinder 804 contracts to loosen the clamp 802.

[0049] The working process of the present invention is as follows: the bagging support device 1 on the right side is first located at the starting position, the bag grabbing and conveying device 6 grabs the inner film bag of the bag making machine 3 or the outer bag bin device 4 and sends it to the bag holding and bagging device 5, the inner film bag is put on the bagging support device 1 on the right side by the bag holding and bagging device 5, the inner film bag is cut by the cutting knife, and the bagging support device 1 on the right side is propped up, as shown in FIG. Figure 2 As shown in the upper left part, the two groups of bagging support devices 1 then move to the right at the same time. During the movement to the right, a horizontal pressure-sensitive adhesive is sprayed on the upper and lower surfaces of the opening periphery of the inner film bag of the right bagging support device 1. After moving into place (sensed by a photoelectric sensing switch, which belongs to the prior art and will not be described in detail here), the bagging support device 1 on the left performs the same action of putting on the inner film bag as before, and the bagging support device 1 on the right performs a sleeve-shaped woven bag (also achieved by the bag grabbing and conveying device 6, the outer bag bin device 4, and the bag supporting and bagging device 5. The process is the same as that of putting on the inner film bag and will not be described in detail here). In addition, as mentioned above, the upper bag suction plate 501 and the lower bag suction plate 502 of the bag supporting and bagging device 5 move inward at the same time to compact the support frame plate 114, so that the inner film bag and the cylindrical woven bag are further fitted together through compaction, and then, as shown in FIG. Figure 2 As shown in the upper right figure, in addition, the material clamping device 8 extends out to take the finished product on the right bagging support device 1 and send it to the finished product receiving bin 7 for storage. Figure 2 As shown in the lower right figure, the two sets of bagging support devices 1 then move to the left at the same time. Figure 2 As shown in the lower left figure, at this time, there is no packaging material on the right bagging support device 1. During the movement to the left, another set of upper and lower glue spraying devices 2 spray glue on the opening of the inner film bag of the left bagging support device 1. Finally, the right bagging support device 1 continues to put on the inner film bag again, and the left bagging support device 1 puts on the cylindrical woven bag for bonding, cutting, and removing the finished product. At this point, a cycle is completed, and the double-station inner cylindrical woven bag is realized. Before putting on, the opening of the inner film bag is sprayed with glue and bonded to form a double-layer cylindrical packaging bag with the inner and outer layers bonded together at the opening.

[0050] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
