Description

Technical Field

[0001] The invention belongs to the field of packaging equipment, and in particular relates to a can cover packaging device. Background Art

[0002] When producing the can lid, the metal material is first punched into a basic lid by a basic lid punch, then curled by a curling machine, injected with glue by a glue injection machine, and dried by a dryer. Then, these lids are further formed on a combined punch and the pull ring is riveted to the lid.

[0003] For the convenience of storage and transportation, the can lid is packed when it is stored or transported, which requires a packing device for putting the can lid into a packaging bag. The packaging bag is generally made of paper and is in a long cylindrical shape with one end open, as shown in FIG14 , so the so-called packing is to put the can lid into the bag from one end of the packaging bag, and then glue the open end to close it.

[0004] There are some reports on packaging equipment for can lids abroad, but most of them only realize automation of a certain section of the packaging process, and the whole machine is also complicated. Summary of the invention

[0005] The invention provides a can cover packaging device, the purpose of which is to push the cover into a packaging bag for packaging, and the action process is accurate and smooth.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a can lid packaging device, comprising a frame and a lid track provided on the frame for conveying stacked lids, a section of the lid track serving as a lid pushing and bagging section, one end of the lid pushing and bagging section serving as a packaging bag supply position, and the other end serving as a lid bagging position;

[0007] The packaging bag supply position is provided with a packaging bag positioning and opening component, which can place the packaging bag on the packaging bag supply position and keep it in an open state;

[0008] A bag grabbing assembly is slidably connected between the bag entry position of the cover body and the packaging bag supply position, and the bag grabbing assembly is driven by a bag grabbing translation driving mechanism to move between the bag entry position of the cover body and the packaging bag supply position; the bag grabbing assembly includes a first opening member and a bag pressing block, and the bag pressing block is arranged opposite to the first opening member, and the bag pressing block is driven by the bag pressing block driving mechanism to approach or move away from the first opening member, so that the bag pressing block and the first opening member cooperate to have a clamping effect; when the bag grabbing assembly is located at the packaging bag supply position, the first opening member can extend into the opening of the packaging bag, and the bag pressing block and the first opening member cooperate to clamp one side edge of the opening of the packaging bag; when the bag grabbing assembly is located at the bag entry position of the cover body, the first opening member can open and maintain the bag opening of the packaging bag;

[0009] The can cover packaging device also includes a cover pushing mechanism, which can push the cover through the first opening member into the packaging bag at the cover pushing and bagging section.

[0010] In the above scheme, at least one second opening is also provided at the bag opening of the packaging bag corresponding to the bag entry position of the cover body. When the bag grabbing assembly is located at the bag entry position of the cover body, the second opening member can also extend into the opening of the packaging bag, and work together with the first opening member to open and maintain the bag opening of the packaging bag; the first opening member is an arc-shaped plate-like body, and the second opening member is also an arc-shaped plate-like body, and the first opening member and the second opening member are arranged opposite to each other with their arc concave surfaces.

[0011] In the above scheme, the bag grabbing assembly also includes at least one second opening-stretching member, which moves with the first opening-stretching member. When the bag grabbing assembly is located at the packaging bag supply position, the second opening-stretching member can extend into the opening of the packaging bag together with the first opening-stretching member; when the bag grabbing assembly is located at the cover bag entry position, the second opening-stretching member can work together with the first opening-stretching member to open and maintain the bag opening of the packaging bag.

[0012] In the above scheme, a packaging bag rear end limit assembly is also provided on the push cover bagging section near the packaging bag supply position. The packaging bag rear end limit assembly consists of a packaging bag rear end limit block and a limit block driving mechanism. The packaging bag rear end limit block can be raised and lowered relative to the frame under the drive of the limit block driving mechanism. When the cover body enters the packaging bag of the push cover bagging section along the cover body track, the packaging bag rear end limit block is in a descending state, that is, it blocks and positions the rear end of the packaging bag. In practice, it is also possible not to provide a packaging bag rear end limit assembly. By controlling the distance that the push mechanism pushes the cover body into the bag, it can also ensure that the push is not excessive and the packaging bag is not broken.

[0013] In the above scheme, the bag pressing block driving mechanism includes a rocker arm, a touch-matching block and a touch-matching block driving device; the rocker arm is hinged relative to the first mouth-supporting member, one end of the rocker arm is positioned and connected to the bag pressing block, and the other end thereof serves as a touch end; an elastic element acts on the rocker arm to keep the bag pressing block in a clamping state in cooperation with the first mouth-supporting member; the touch-matching block is arranged at the packaging bag supply position corresponding to the touch end of the rocker arm, and the touch-matching block has two working positions under the drive of the touch-matching block driving device, when the touch-matching block is located at one working position, the touch end of the rocker arm contacts the touch-matching block to make the bag pressing block descend and release, and when the touch-matching block is located at another working position, it makes way for the touch end of the rocker arm, so that the bag pressing block returns to a clamping state. The above is a preferred example of a bag pressing block driving mechanism, and in practice, an actuator can also be directly used to drive the bag pressing block to move, but this actuator needs to move with the bag grabbing assembly.

[0014] In the above scheme, a folding bag assembly is also provided on the cover-pushing bag-filling section near the bag-entering position of the cover body, and the folding bag assembly includes a clamping drive mechanism, a rotating drive mechanism, a clamping claw assembly and a linear drive mechanism. The clamping drive mechanism is driven by the rotating drive mechanism to perform a swinging motion, and the clamping drive mechanism has two clamping parts; the clamping claw assembly includes an upper bag-folding rod and a lower bag-folding rod that are relatively arranged, and the roots of the upper bag-folding rod and the lower bag-folding rod are fixed on the two clamping parts of the clamping drive mechanism, and the clamping drive mechanism drives the upper bag-folding rod and the lower bag-folding rod to separate from each other, so as to separate the upper bag-folding rod and the lower bag-folding rod from each other. An opening is formed between the bag rods; and a pressure cover is provided on the lower bag folding rod, and the pressure cover is provided with an arc-shaped pressing surface that matches the circumferential surface of the packaging bag, and the arc-shaped pressing surface is extended along the axial direction of the packaging bag; in the working state, the open end of the packaging bag is disposed in the opening between the upper bag folding rod and the lower bag folding rod, and the clamping drive mechanism drives the upper bag folding rod and the lower bag folding rod to clamp the open end of the packaging bag, and the rotating drive mechanism drives the upper bag folding rod and the lower bag folding rod to flip 180°, so that the arc-shaped pressing surface of the pressure cover is folded back with the open end on the position of the cover body in the packaging bag to complete the bag mouth folding.

[0015] Furthermore, the rotary drive mechanism is also provided with a linear drive mechanism, through which the rotary drive mechanism can be driven to perform linear motion in a direction perpendicular to the axis of the packaging bag.

[0016] Furthermore, the folding packaging bag assembly also includes a heating assembly, which is arranged corresponding to the folded position of the opening end after the bag mouth is folded, so as to heat the folded opening end and the position of the cover body in the packaging bag to facilitate bonding after the bag mouth is folded.

[0017] Furthermore, the folding packaging bag assembly also includes two top pressing blocks and a top pressing block driving mechanism. The two top pressing blocks are arranged opposite to each other on both sides of the packaging bag in the radial direction. The two top pressing blocks are in a narrowed pointed shape toward the head of the packaging bag. Under the action of the top pressing block driving mechanism, the two top pressing blocks extend into the folds on both sides of the packaging bag or retreat.

[0018] The above-mentioned folding bag assembly is an optional part selected according to user needs. The actual equipment may not be equipped with the folding bag assembly. The equipment does not necessarily need to complete the sealing step. For example, other equipment or manual sealing can be used after the cover is bagged.

[0019] In the above scheme, the cover pushing mechanism can be directly a linear moving mechanism arranged along the guide rail, such as a linear motor, a motor and a screw-nut mechanism. However, a better scheme is that the cover pushing mechanism includes a lifting mechanism, a guide rail, a push rod and a push rod driving mechanism, and the lifting mechanism has a lifting end; the guide rail is arranged below the cover track and extends along the length direction of the cover track, one end of the guide rail is rotatably connected to the frame, and the other end is rotatably connected to the lifting end of the lifting mechanism, and is driven by the lifting mechanism to move up and down in the vertical direction; the push rod is slidably connected to the guide rail along the length direction of the guide rail, and the push rod has a push end, which corresponds to the cover on the cover track; the push rod is transmission-connected to the push rod driving mechanism, and is driven by the push rod driving mechanism to make linear motion along the length direction of the cover track. The effect of this preferred solution is that the pushing mechanism can be lowered and retracted when not in use, saving space; at the same time, compared with the overall lifting of the guide rail, the connection and driving method of the guide rail has a small burden on the lifting mechanism, and the lifting of the guide rail is more convenient, which is more suitable for use with longer guide rail strokes.

[0020] In the above scheme, the packaging bag supply position is connected to a packaging bag supply device, which includes a material bin, a bag taking arm, an arm driving member and a bag taking operation assembly; the material bin includes a material storage trough, which is fixedly arranged relative to the frame, one end of the material storage trough is a material taking end, and the material storage trough is arranged with the material taking end tilted downward; the upper end of the bag taking arm is hinged relative to the frame, and the lower end of the bag taking arm serves as the bag taking operation end; one end of the arm driving member is hinged relative to the frame, and the other end is hinged to the middle part of the bag taking arm, and the arm driving member is hinged to the frame, and the other end is hinged to the middle part of the bag taking arm. The driving member drives the bag taking arm to swing; the bag taking operation component is arranged on the bag taking operation end of the bag taking arm, and the bag taking operation component is slidably connected with the bag taking arm along the length direction of the bag taking arm, and a telescopic driving mechanism acts on the bag taking operation component, so that the bag operating component can perform telescopic movement along the length direction of the bag taking arm; in the working state, the arm driving member drives the bag taking arm to swing toward the material taking end of the storage trough, and aligns with the material taking end of the storage trough, so that the bag taking operation component can be driven by the telescopic driving mechanism to extend into the material taking end of the storage trough to take out the packaging bag.

[0021] In the above scheme, the second opening member is provided with an air blowing channel toward the bag opening of the packaging bag that is opened by the second opening member, and the air blowing channel is connected to an air source to fully open the packaging bag to facilitate the installation of the cover body.

[0022] In the above scheme, the packaging bag positioning and opening component can adopt various mechanisms, such as a cylinder plus a suction cup, etc. The best one is as follows: it includes an upper adsorption component and a lower adsorption component, and the upper adsorption component and the lower adsorption component are arranged correspondingly up and down, and are adsorbed on the packaging bag from the top and bottom to open the bag mouth of the packaging bag.

[0023] In the above scheme, the cover pushing and bagging section may also be provided with a discharge device, and when the cover body is put into the packaging bag and packed, it can be discharged or grabbed by the discharge device. The discharge device may be, for example, two gates at the bottom of the track, and when the gates are opened, the packed cylindrical cover body will automatically fall off for discharge, or the discharge device may be a manipulator, and the manipulator may grab and remove the packed cylindrical cover body. Of course, in practice, no discharge device is provided, and manual discharge is also possible.

[0024] The present invention has the following effects: the present invention realizes that the cover body can be automatically loaded into the packaging bag accurately and smoothly by adopting ingenious mechanism designs such as the bag grabbing assembly. The whole device is ingeniously designed, the bag loading efficiency is high, and the cost of the whole machine is not high, and it has great market prospects.

[0025] In addition, since the present invention has two workstations, namely, a packaging bag supplying position and a cover bag inserting position, the bag mouth of the packaging bag is first opened at the packaging bag supplying position, and then the packaging bag is clamped by the bag grabbing assembly and dragged to the packaging bag supplying position. After the bag mouth of the packaging bag is reliably opened at the packaging bag supplying position, the cover body is pushed into the packaging bag to complete the bagging process, that is, opening the bag mouth and bagging with the bag mouth supported are completed in two workstations. This design is to enable the bag mouth of a new packaging bag to be opened at the packaging bag supplying position, while the cover bag inserting and bagging process of the previous packaging bag is carried out at the cover bag inserting position. These two steps can be carried out simultaneously, thus avoiding waiting time and improving the work rhythm and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0047] Example: See Figure 1-19 As shown:

[0048] A can lid packaging device, see Figure 1 , Figure 2 As shown in Figure 3, it includes a frame 1 and a cover track 2 for conveying stacked covers on the frame 1, a section of the cover track 2 is used as a cover pushing and bagging section 21, and the cover pushing and bagging section 21 refers to the section on the equipment that completes the core function of pushing the cover 001 into the packaging bag 00.

[0049] See also Figure 2 As shown, one end of the cover pushing and bagging section 21 serves as a packaging bag supply position 211 , and the other end thereof serves as a cover body bag entry position 212 .

[0050] See also Figure 1 , Figure 2 As shown in FIG3 , the packaging bag supply position 211 is provided with a packaging bag positioning and opening component 3, which can place the packaging bag on the packaging bag supply position 211 and keep it in an open state. Fig.19 As shown, it includes an upper adsorption component 31 and a lower adsorption component 32, which are arranged correspondingly from top to bottom, and adsorb on the packaging bag 00 from top and bottom to open the bag mouth of the packaging bag 00. In practice, the packaging bag positioning and opening component 3 can also be implemented in other structural forms: for example, two clamping plates, one on the left and one on the right, clamp the left and right side edges of the packaging bag 00 to open the bag mouth naturally, or the upper and lower adsorption and the left and right clamping plates work together to open the bag mouth.

[0051] See also Figure 1 , Figure 2 As shown in FIG. 3 , a bag grabbing assembly 4 is slidably connected between the cover bag entry position 212 and the packaging bag supply position 211 , and the bag grabbing assembly 4 is driven by a bag grabbing translation driving mechanism 44 to move between the cover bag entry position 212 and the packaging bag supply position 211 .

[0052] See also Figure 1 , Figure 2 As shown in FIG3 , the bag grabbing assembly 4 includes a first opening support member 41 and a bag pressing block 42. The first opening support member 41 is an arc-shaped plate with a concave surface facing upward. The bag pressing block 42 is located below the first opening support member 41. The bag pressing block 42 is driven by the bag pressing block driving mechanism 43 to approach or move away from the bottom surface of the first opening support member 41, so that the bag pressing block 42 cooperates with the first opening support member 41 to have a clamping effect; when the bag grabbing assembly 4 is located at the packaging bag supply position 211, the first opening support member 41 can extend into the opening of the packaging bag 00, and the bag pressing block 42 cooperates with the first opening support member 41 to clamp the lower edge of the opening of the packaging bag 00.

[0053] See also Figure 1 , Figure 2 As shown in FIG. 3 , the translation drive mechanism 44 may adopt various existing linear drive mechanisms, such as a linear motor, a linear module, a motor plus a lead screw nut mechanism, or a cylinder.

[0054] See also Figure 1 , Figure 2 As shown in Figure 3 and Figures 4-7 for details, the bag pressing block driving mechanism 43 preferably includes a rocker arm 431, a touch matching block 432 and a touch matching block driving device 433. The rocker arm 431 is hinged relative to the first mouth-supporting member 41, one end of the rocker arm 431 is fixed to the bag pressing block 42, and the other end thereof serves as a touch end 4311. Specifically, as shown in Figures 3-6, the rocker arm 431 is a bending rod, the end of its transverse section is positioned and connected to the bag pressing block 42, and the end of its vertical section serves as a touch end 4311. An elastic element 434 is also provided on the end of the transverse section of the rocker arm 431 to keep the bag pressing block 42 in a clamping state in cooperation with the first mouth-supporting member 41. See. Figure 1 and Figure 2As shown in Figures 3-6, the touch matching block 432 is arranged at the packaging bag supply position 211 corresponding to the touch end 4311 of the rocker arm 431, and the touch matching block 432 has two working positions under the drive of the touch matching block driving device 433. When the touch matching block 432 is located at one working position, the touch end 4311 of the rocker arm 431 contacts the touch matching block 432 to make the bag pressing block 42 descend and release, and when the touch matching block 432 is located at another working position, it is to make way for the touch end 4311 of the rocker arm 431, so that the bag pressing block 42 returns to the clamping state.

[0055] In practice, the bag pressing block driving mechanism 43 may also adopt other existing driving mechanisms, such as a cylinder directly installed on the bag grabbing assembly 4 to move with the bag grabbing assembly 4 .

[0056] See also Figure 1 , Figure 2 As shown in FIG3 , a second opening member 51 and a second opening member driving mechanism 52 for driving the second opening member 51 are provided at the bag entry position 212 of the cover body, and the second opening member 51 is located above the first opening member 41. When the bag grabbing assembly 4 is located at the bag entry position 212 of the cover body, the second opening member 51 and the first opening member 41 work together to open and maintain the bag opening, forming a passage for the cover body to enter. Preferably, the second opening member 51 is a circular arc plate with a concave surface facing downward. The cross section of the first opening member 41 is close to a semicircle.

[0057] Also, see Figure 1 , Figure 2 As shown in FIG3 , a blowing channel 511 is preferably provided on the second opening-stretching member 51 toward the bag opening of the packaging bag 00 that is stretched open. The blowing channel 511 is connected to an air source to blow air into the packaging bag 00 while the bag opening of the packaging bag 00 is stretched open by the second opening-stretching member 51 and the first opening-stretching member 41, so that the bag opening of the packaging bag 00 can be opened smoothly.

[0058] The can lid packaging device further comprises a lid pushing mechanism 6 , which can push the lid through between the second opening support member 51 and the first opening support member 41 and enter into the packaging bag 00 at the lid pushing and bagging section 21 .

[0059] See also Figure 1 and Figure 2 As shown, a packaging bag rear end limiting assembly 7 is also provided on the cover pushing and bagging section 21 near the packaging bag supply position 211. The packaging bag rear end limiting assembly 7 is composed of a packaging bag rear end limiting block 71 and a limiting block driving mechanism 72. The packaging bag rear end limiting block 71 can be raised and lowered relative to the frame 1 under the drive of the limiting block driving mechanism 72. When the cover body enters the packaging bag 00 of the cover pushing and bagging section 21 along the cover body track 2, the packaging bag rear end limiting block 71 is in a descending state, that is, it blocks and positions the rear end of the packaging bag 00.

[0060] When working, Figure 1-2 3, the cover track 2 of this embodiment is arranged with stacked covers 001. Figure 8 , a packaging bag 00 with an open bag mouth is set at the packaging bag supply position 211, and the bag grabbing translation driving mechanism 44 is first started to drive the bag grabbing assembly 4 to move toward the packaging bag supply position 211. The state at this time is shown in Figure 4. When the bag grabbing assembly 4 is about to reach the packaging bag supply position 211, the touching end 4311 of the swing rod 431 first contacts and is pressed by the touching matching block 43, so that the bag pressing block 42 descends, that is, it is separated from the first opening member 41, and the bag grabbing assembly 4 continues to move toward the packaging bag supply position 211, so that the first opening member 41 is inserted into the open bag mouth of the packaging bag 00. The state at this time is shown in Figure 5; immediately afterwards, the touching matching block driving device 433 is actuated to drive the touching matching block 43 to swing and give way, and the bag pressing block 42 is reset and lifted up under the action of the elastic element 434 to cooperate with the first opening member 41 to clamp the lower edge of the bag mouth of the packaging bag 00. The state at this time is shown in Figure 5. Figure 6 Then, the grab bag translation drive mechanism 44 is started to drive the grab bag assembly 4 to move toward the cover bag entry position 212, and the grab bag assembly 4 successfully grabs a bag and drags it to the cover bag entry position 212. This process is referred to Figure 7 When the bag grabbing assembly 4 returns to the cover body bag entry position 212, the second opening member 51 is also inserted into the open bag mouth of the packaging bag 00, and then the second opening member 51 is driven by the second opening member driving mechanism 52 to move away from the first opening member 41, that is, the second opening member 51 and the first opening member 41 are relatively opened, and at the same time, the blowing channel 511 blows air into the packaging bag 00, so that the bag mouth of the packaging bag can be smoothly inflated and opened, forming a channel for the cover body 001 to enter the bag. At this time, the cover body pushing mechanism 6 is started, that is, the stack of long strips of cover bodies 001 on the cover body track 2 is pushed into the bag, and the cover body pushing mechanism 6 withdraws from the packaging bag 00, that is, the process of loading the cover body into the packaging bag 00 for packaging is completed.

[0061] The cover pushing mechanism 6 is any mechanism that can push the cover into the packaging bag 00 along the axial direction of the packaging bag 00, such as a cylinder arranged along the axial direction of the packaging bag 00. However, the preferred solution in this embodiment is: Figure 1 and Figure 2 As shown, see Figure 8 ,and Fig. 9As shown, the cover pushing mechanism 6 includes a lifting mechanism 61, a guide rail 62, a push rod 63 and a push rod driving mechanism 64. The lifting mechanism 61 has a lifting end. The guide rail 62 is arranged below the cover track 2 and extends along the length direction of the cover track 2. One end of the guide rail 62 is rotatably connected to the frame 1, and the other end is rotatably connected to the lifting end of the lifting mechanism 61, and is driven by the lifting mechanism 61 to move up and down in the vertical direction. The push rod 63 is slidably connected to the guide rail 62 along the length direction of the guide rail 62. The push rod 63 has a push end, which corresponds to the cover on the cover track 2. The push rod 63 is transmission-connected to the push rod driving mechanism 64, and is driven by the push rod driving mechanism 64 to make linear motion along the length direction of the cover track 2. The push rod driving mechanism 64 can be an existing driving device such as a linear module, a linear motor, etc.

[0062] In working state, see Figure 1 -3, see Figure 8-9 The cover body 001 is transported along the cover body track 2 to the right side of the pushing end of the push rod 63, the lifting end of the lifting mechanism 61 pushes the guide rail 62 to rise, and the pushing end of the push rod 63 extends upward from the middle of the cover body track 2. Then the push rod driving mechanism 64 starts to drive the pushing end of the push rod 63 to slide along the length direction of the guide rail 62, pushing the cover body 001 to move in the cover body track 2.

[0063] Preferably, the push rod 63 further includes an extension section, which is extended along the length direction of the cover rail 2, and the end of the extension section serves as the abutment end.

[0064] See also Figure 1 , 2 As shown, see Figure 10-13A folding bag assembly 8 is also provided on the cover-pushing bagging section 21 near the cover-body bag-entering position 212. The folding bag assembly 8 includes a clamping drive mechanism 81, a rotating drive mechanism 82, and a clamping claw assembly 83. The clamping drive mechanism 81 is driven by the rotating drive mechanism 82 to perform a swinging motion. The clamping drive mechanism 81 has two clamping parts 811. The clamping claw assembly 83 includes an upper bag-folding rod 831 and a lower bag-folding rod 832 that are arranged opposite to each other. The roots of the upper bag-folding rod 831 and the lower bag-folding rod 832 are fixed on the two clamping parts 811 of the clamping drive mechanism 81. The clamping drive mechanism 81 drives the upper bag-folding rod 831 and the lower bag-folding rod 832 to separate, thereby forming an opening between the upper bag-folding rod 831 and the lower bag-folding rod 832.
