Description

Technical Field

[0001] The present invention relates to the technical field of filling production equipment, and particularly relates to a positive and negative integrated boxing device. In addition, the present invention also relates to a filling production line adopting such a positive and negative integrated boxing device. Background Art

[0002] At present, many canned foods, such as fruit juices, milk, yogurt, tomato ketchup, jelly and other foods, are automatically produced by a filling production line. Generally, a boxing device is arranged downstream of the filling production line, and the products are boxed and packed through the boxing device, which helps to improve the packing efficiency. However, when boxing, the products in each layer of the existing boxing device of the filling production line are generally placed unidirectionally. For some products with a large difference in upper and lower dimensions, the gap between adjacent products in the same layer is relatively large, which is not conducive to reasonably and fully utilizing the internal space of the packing box, resulting in a large consumption of packing boxes and being not conducive to reasonably reducing the boxing cost. Summary of the Invention

[0003] In order to solve the above-mentioned disadvantages and deficiencies existing in the prior art, the present invention provides a positive and negative integrated boxing device, which integrally packs the products in a positive and negative staggered manner into the packing box when boxing, reasonably increasing the number of products in each layer and being conducive to reasonably and fully utilizing the internal space of the packing box.

[0004] In order to achieve the above technical purpose, a positive and negative integrated boxing device provided by the present invention includes

[0005] An output belt for outputting products,

[0006] A suction and release mechanism for sucking the products on the output belt and putting the products into the packing box,

[0007] The output belt includes a first output belt for outputting products in an m×n array manner and a second output belt for outputting products in an (m + 1)×(n + 1) array manner,

The first suction cup structure is flip - set and is provided with pre - taking suction cups distributed in an m×n array manner. The first suction cup structure has a suction position above the first output belt and a transition position below the second suction cup structure. The second suction cup structure is movably set and is provided with positive - taking suction cups distributed in an m×n array manner and reverse - taking suction cups distributed in an (m + 1)×(n + 1) array manner.

The guide post is provided with an air flow channel communicating with the positive suction cup, and the seat plate is provided with an avoidance hole for avoiding the positive suction cup.

[0012] Preferably, the second suction cup structure includes a guard plate structure arranged at the bottom of the seat plate and surrounding all the negative suction cups. The guard plate structure includes a plurality of guard plates distributed at intervals. The outer dimension of the guard plate structure is smaller than the inner dimension of the packing box.

[0013] Preferably, the second suction cup structure includes a guide sleeve fixed to the frame plate and a guide rod passing through the guide sleeve. The guide rod is vertically arranged and its bottom end is connected to the lifting plate.

[0014] Preferably, the positive and negative integrated packing device includes a horizontal driving structure for driving the second suction cup structure to move horizontally in a direction perpendicular to the output direction of the second output belt, and a vertical driving structure for driving the second suction cup structure to lift. The horizontal driving structure drives the second suction cup structure to switch between the positive suction position, the negative suction position and the packing position.

[0015] Preferably, the positive and negative integrated packing device includes a flipping structure for driving the first suction cup structure to flip so as to switch the first suction cup structure between the suction position and the transition position. The flipping structure includes a frame arranged above the first output belt, a rotating shaft rotatably arranged on the frame, and a flipping motor for driving the rotating shaft to rotate. The axial direction of the rotating shaft is parallel to the output direction of the first output belt, and the first suction cup structure is arranged on the rotating shaft.

[0016] Preferably, the first suction cup structure includes a base plate and a sheath. The pre-suction cup and the sheath are arranged on the same side of the base plate. The sheath and the pre-suction cup are arranged in one-to-one correspondence and are arranged outside the corresponding pre-suction cup. The flipping structure includes a bracket for mounting the first suction cup structure and a pre-suction cylinder for driving the first suction cup structure to lift. The bracket is fixed to the rotating shaft, the pre-suction cylinder is fixed to the bracket, and the base plate is connected to the piston rod of the pre-suction cylinder.

[0017] The present invention also provides a filling production line, including the above-mentioned positive and negative integrated packing device.

[0018] After adopting the above technical solutions, the present invention has the following advantages:

[0019] 1. The positive and negative integrated packing device provided by the present invention outputs products in different array modes through the first output belt and the second output belt. During packing, the first suction cup structure first sucks the product on the first output belt at the suction position and then flips to the transition position corresponding to the second suction cup structure. The positive suction cup of the second suction cup structure sucks the product on the first suction cup structure at the positive suction position, and then the reverse suction cup of the second suction cup structure sucks the product on the second output belt at the reverse suction position. Finally, the second suction cup structure places the sucked products into the packing box at the packing position. Through the cooperation of the first suction cup structure and the second suction cup structure, the products sucked by the positive suction cup are located between several adjacent products sucked by the reverse suction cup, making full use of the gaps between several adjacent products in the same direction to add products. After the products are placed in the packing box, the products in each layer are distributed in a positive and negative staggered manner, which is beneficial to reasonably and fully utilize the internal space of the packing box, increase the number of products that the packing box can accommodate, and is beneficial to reasonably reduce the packing cost.

[0020] 2. When the second suction cup structure is in the packing position, the positive suction cup is higher than the reverse suction cup, so that the positive products sucked by the positive suction cup are higher than the reverse products sucked by the reverse suction cup, and the positive products and the reverse products are distributed in a staggered manner up and down. This is convenient for reasonably reducing the overall dimension of all the products sucked by the second suction cup structure, enabling the second suction cup structure to smoothly place the products into the packing box and avoiding the interference between the products on the outer circle and the packing box when the second suction cup structure places the products into the packing box. After the products are placed in the packing box, the positive products automatically move downward under their own weight, causing the products in the same layer to spread out and cover the packing box.

[0021] 3. The lifting plate is driven by a lifting cylinder. The lifting plate provided with the positive suction cup can move up and down relative to the seat plate provided with the reverse suction cup. The lifting cylinder can drive the lifting plate to rise so that the positive suction cup is higher than the reverse suction cup, thereby providing sufficient working space for the second suction cup structure to suck the reverse products at the reverse suction position and enabling the reverse suction cup to firmly suck the reverse products.

[0022] 4. A guard plate structure surrounding all the reverse suction cups is arranged at the bottom of the seat plate. The guard plate structure adopts a structure with several guard plates spaced apart. The overall dimension of the guard plate structure is smaller than the internal dimension of the packing box. By restricting the overall dimension of the second suction cup structure after sucking the positive products and the reverse products through the guard plate structure, the second suction cup structure can smoothly place the products downward into the packing box and avoid the interference between the products and the packing box.

[0023] 5. The horizontal drive structure drives the second suction cup structure to switch between the positive suction position, the reverse suction position, and the packing position, and the vertical drive structure drives the second suction cup structure to move up and down. Through the cooperation of the horizontal drive structure and the vertical drive structure, the second suction cup structure can smoothly suck the positive products on the first suction cup structure at the positive suction position, suck the reverse products on the second output belt at the reverse suction position, and smoothly place the products into the packing box at the packing position.

[0024] 6. The flipping motor of the flipping structure drives the rotating shaft to rotate relative to the frame, and the rotating shaft drives the first suction cup structure to flip so that the first suction cup structure switches between the suction position and the transition position. The products sucked by the first suction cup structure are inverted after flipping, which is convenient for being sucked by the second suction cup structure, enabling the products to smoothly transition from the first suction cup structure to the second suction cup structure.

[0025] 7. When the first suction cup structure sucks the products at the suction position, the pre-picking cylinder drives the substrate to move downward so that the pre-picking suction cup can smoothly suck the products. The products sucked by the pre-picking suction cup are located in the corresponding sheaths, enabling the products to maintain a stable position when following the flipping of the first suction cup structure, so that the products on the first suction cup structure can be smoothly sucked by the second suction cup structure.

[0037] First embodiment

[0038] As Figures 1 to 9As shown in the figure, an integrated front and back packing device provided in the first embodiment of the present invention includes an output belt 200 and a suction and placement mechanism. The output belt is used to output products 100, and the suction and placement mechanism is used to suck the products 100 on the output belt 200 and place the products 100 into a packing box 600. The output belt 200 includes a first output belt 210 that outputs products 100 in an m×n array manner and a second output belt 220 that outputs products 100 in an (m + 1)×(n + 1) array manner. The suction and placement mechanism includes a first suction cup structure 300 and a second suction cup structure 400. The first suction cup structure 300 is flip - set and is provided with pre - fetch suction cups 310 distributed in an m×n array manner. The first suction cup structure 300 has a suction position above the first output belt 210 and a transition position below the second suction cup structure 400. The second suction cup structure 400 is movably set and is provided with positive - fetch suction cups 410 distributed in an m×n array manner and reverse - fetch suction cups 420 distributed in an (m + 1)×(n + 1) array manner. The positive - fetch suction cups 410 and the reverse - fetch suction cups 420 are staggered, and each positive - fetch suction cup 410 is located between four adjacent reverse - fetch suction cups 420. The second suction cup structure 400 has a positive - suction position above the first suction cup structure 300, a reverse - suction position above the second output belt 220, and a packing position corresponding to the packing box 600 up and down. When the second suction cup structure 400 is in the positive - suction position, the positive - fetch suction cups 410 and the pre - fetch suction cups 310 are corresponding up and down.

[0039] During packing, the first suction cup structure first sucks the products on the first output belt at the suction position and then flips to the transition position to correspond to the second suction cup structure. The positive - fetch suction cups of the second suction cup structure suck the products on the first suction cup structure at the positive - suction position. Then, the reverse - fetch suction cups of the second suction cup structure suck the products on the second output belt at the reverse - suction position. Finally, the second suction cup structure places the sucked products into the packing box at the packing position. Through the cooperation of the first suction cup structure and the second suction cup structure, the products sucked by the positive - fetch suction cups are located between several adjacent products sucked by the reverse - fetch suction cups, making full use of the gaps between several adjacent products in the same direction to add products. After the products are placed in the packing box, each layer of products is distributed in a positive - negative staggered manner, which is conducive to reasonably and fully utilizing the internal space of the packing box, increasing the number of products that the packing box can accommodate, and is conducive to reasonably reducing the packing cost.

[0040] The filled product 100 is conveyed onto the output belt 200 through the carrier plate 500, and the quantity and distribution mode of the products 100 on each carrier plate 500 are the same. In order to enable the output belt 200 to output the products 100 according to the quantity of the products 100 carried by the carrier plate 500 to meet the requirements of the array mode, m and n simultaneously meet the two requirements of m + 1 = 2n and m = n + 1. In this embodiment, m is set to 3 and n is set to 2. The first output belt 210 outputs the products 100 in groups of one carrier plate 500, that is, the first output belt 210 outputs the products 100 in an array mode of 3×2. The second output belt 220 outputs the products 100 in groups of two carrier plates 500, that is, the second output belt 220 outputs the products 100 in an array mode of 4×3. Both the first output belt 210 and the second output belt 220 output the products 100 in an inverted manner. The first output belt 210, the second output belt 220 and the packing box 600 are distributed in parallel in the left-right direction. The first output belt 210 and the second output belt 220 drive the products 100 to move forward from back to front through the carrier plate 500.

[0041] Combined with Figure 2 、 Figure 3 、 Figure 4 , the front-back and positive-negative integrated packing device includes a flipping structure 700 for driving the first suction cup structure 300 to flip. The flipping structure 700 includes a frame 710 disposed above the first output belt 210, a rotating shaft 720 rotatably disposed on the frame 710, and a flipping motor 730 for driving the rotating shaft 720 to rotate. The axial direction of the rotating shaft 720 is parallel to the output direction of the first output belt 210, and the first suction cup structure 300 is disposed on the rotating shaft 720. In this embodiment, the frame 710 includes two support plates 711 distributed front and back and a plurality of support rods 712 for fixing the two support plates 711. The front end of the support rod 712 is fixedly connected to the front support plate 711, and the rear end is fixedly connected to the rear support plate 711. The axial direction of the rotating shaft 720 is horizontally disposed in the front-back direction. The two ends of the rotating shaft 720 are respectively rotatably mounted on the two support plates 711 through bearings. The flipping motor 730 is fixed to one side of the bracket 740, and the flipping motor 730 drives the rotating shaft 720 to rotate through a reducer.

[0042] The flipping structure 700 further includes a bracket 740 for mounting the first suction cup structure 300 and a prefetching cylinder 750 for driving the first suction cup structure 300 to lift and lower. The bracket 740 is fixed on the rotating shaft 720, the prefetching cylinder 750 is fixed on the bracket 740, and the first suction cup structure 300 is connected to the piston rod of the prefetching cylinder 750. The first suction cup structure 300 further includes a base plate 320 and a sheath 330. The prefetching suction cups 310 and the sheath 330 are arranged on the same side of the base plate 320. The sheath 330 and the prefetching suction cups 310 are arranged in one-to-one correspondence, and the sheath 330 is located outside the corresponding prefetching suction cup 310. In this embodiment, the prefetching suction cups 310 and the sheath 330 are both distributed on the base plate 320 in a 3×2 array. There are three first suction cup structures 300 spaced apart in the front-rear direction on the bracket 740. Correspondingly, there are also three prefetching cylinders 750 and they are arranged in one-to-one correspondence with the first suction cup structures 300. The cylinder body of the prefetching cylinder 750 is fixed on the bracket 740, the piston rod of the prefetching cylinder 750 is fixedly connected to the base plate 320 of the corresponding first suction cup structure 300, and the prefetching suction cups 310 and the sheath 330 are arranged on the side of the base plate 320 facing away from the prefetching cylinder 750. In this embodiment, the positive and negative integrated packing device further includes a first air path structure communicated with each prefetching suction cup 310. The first air path structure sucks air to make the prefetching suction cups 310 suck the product or inflates to make the prefetching suction cups 310 release the product.

[0043] Combined Figure 5 , Figure 6 , Figure 7, the second suction cup structure 400 includes a frame plate 430, a base plate 445 fixed to the bottom of the frame plate 430, a lifting cylinder 450 fixed to the frame plate 430, and a lifting plate 460 driven by the lifting cylinder 450. The lifting plate 460 is arranged above the base plate 445. The positive picking suction cup 410 is arranged at the bottom of the lifting plate 460, and the reverse picking suction cup 420 is arranged at the bottom of the base plate 445. In this embodiment, the second suction cup structure 400 further includes a guide post 470 fixed to the bottom side of the lifting plate 460. The guide posts 470 are arranged in one-to-one correspondence with the positive picking suction cups 410. The positive picking suction cups 410 are arranged at the bottom ends of the corresponding guide posts 470. The guide posts 470 are provided with air flow channels 471 communicated with the positive picking suction cups 410. The positive and reverse integrated packing device further includes a second air path structure communicated with each guide post 470. The second air path structure sucks air to make the positive picking suction cups 410 suck the product or inflates to make the positive picking suction cups 410 release the product. The base plate 445 is fixed to the bottom of the frame plate 430 through a support rod 444.

The positive picking suction cups 410 are distributed in a 3×2 array, and the reverse picking suction cups 420 are distributed in a 4×3 array. A flow channel plate 442 is arranged on the top of the base plate 445. The flow channel plate 442 is provided with several flow channels 443 distributed in parallel and communicated with the reverse picking suction cups 420. The positive and reverse integrated packing device further includes a third air path structure communicated with each flow channel 443. The third air path structure sucks air to make the reverse picking suction cups 420 suck the product or inflates to make the reverse picking suction cups 420 release the product.

[0044] To improve the lifting stability of the lifting plate 460, the second suction cup structure 400 further includes a guide sleeve 491 fixed to the frame plate 430 and a guide rod 492 passing through the guide sleeve 491. The guide rod 492 is vertically arranged and its bottom end is connected to the lifting plate 460. When the lifting cylinder 450 drives the lifting plate 460 to rise or fall, the guide rod 492 moves relative to the guide sleeve 491.

[0045] To enable the second suction cup structure 400 to smoothly place the product 100 into the packing box 600, the second suction cup structure 400 further includes a guard plate structure 480 arranged at the bottom of the base plate 445 and located outside all the reverse picking suction cups 420. The guard plate structure 480 includes several guard plates 481 distributed at intervals. The outer dimension of the guard plate structure 480 is smaller than the inner dimension of the packing box 600. The guard plates 481 are arc-shaped, and the specific shape of each guard plate 481 is slightly different according to the distribution position.

[0046] The positive and negative integrated boxing device further includes a horizontal driving structure for driving the second suction cup structure 400 to move horizontally in a direction perpendicular to the output direction of the second output belt 220, and a vertical driving structure for driving the second suction cup structure 400 to lift and lower. The horizontal driving structure drives the second suction cup structure 400 to switch between the positive suction position, the negative suction position, and the boxing position. In this embodiment, the horizontal driving structure drives the second suction cup structure 400 to move horizontally in the left-right direction. The vertical driving structure includes a liftable table board 800. The second suction cup structure 400 is arranged at the bottom of the table board 800. Three second suction cup structures 400 are arranged at intervals in the front-back direction, and the three second suction cup structures 400 respectively correspond to the three first suction cup structures 300 on the support 740. The vertical driving structure can adopt a structure driven by multiple vertical cylinders. The table board 800 is connected to the bottom end of the piston rod of the vertical cylinder. The horizontal driving structure can adopt a driving method of a motor through a transmission belt.

[0047] Embodiment 1 of the present invention further provides a filling production line, including the positive and negative integrated boxing device described above.

[0048] The flipping structure 700 drives the first suction cup structure 300 to flip back and forth by 180°. Combining Figure 1 , the flipping structure 700 drives the first suction cup structure 300 to flip to above the first output belt 210. At this time, the first suction cup structure 300 is in the suction position, the first suction cup structure 300 faces downward and corresponds to the corresponding carrier plate 500 up and down, so that the pre-taking suction cups 310 correspond to the products 100 on the carrier plate 500 one by one. The pre-taking cylinder 750 drives the first suction cup structure 300 to move downward by a certain distance. The pre-taking suction cups 310 adsorb the corresponding products 100 and the products 100 are located in the sheaths 330. Then the pre-taking cylinder 750 drives the first suction cup structure 300 to move upward and reset. Combining Figure 8 , then, the flipping structure 700 drives the first suction cup structure 300 to flip by 180°, so that the first suction cup structure 300 faces upward and the products 100 are in the correct position. At this time, the first suction cup structure 300 is in the transition position.

[0049] Combining Figure 9, when the second suction cup structure 400 is in the positive suction position, the second suction cup structure 400 corresponds to the first suction cup structure 300 vertically. The lifting cylinder 450 drives the positive suction cup 410 to move downward a certain distance through the lifting plate 460, so that the positive suction cup 410 sucks the product 100 on the first suction cup structure 300. The pre - pickup suction cup 310 of the first suction cup structure 300 releases the product 100, and the lifting cylinder 450 drives the positive suction cup 410 to move upward to reset through the lifting plate 460. Then, the horizontal driving structure drives the second suction cup structure 400 to move leftward above the second output belt 220. At this time, the second suction cup structure 400 is in the reverse suction position, and the second suction cup structure 400 corresponds to the carrier plate 500 on the second output belt 220 vertically. At this position, the vertical driving structure drives the second suction cup structure 400 to move downward a certain distance, so that the reverse suction cup 420 sucks the product 100 located on the second output belt 220. After the suction is completed, the vertical driving structure drives the second suction cup structure 400 to move upward to reset. Subsequently, the horizontal driving structure drives the second suction cup structure 400 to move leftward to correspond to the packing box 600 vertically. At this time, the second suction cup structure 400 is in the packing position. At this position, the vertical driving structure drives the second suction cup structure 400 to move downward to put the product 100 sucked by the second suction cup structure 400 into the packing box 600. The suction cup of the second suction cup structure 400 releases the product 100, and the vertical driving structure drives the second suction cup structure 400 to move upward to reset. Then, the horizontal driving structure drives the second suction cup structure 400 to return to the positive suction position to start the next packing operation.

[0050] Combined with Figure 7 , in order to reasonably reduce the outer dimensions of all products sucked by the second suction cup structure 400, when the second suction cup structure 400 is in the packing position, the positive suction cup 410 is higher than the reverse suction cup 420, so that the positive products sucked by the positive suction cup 410 are higher than the reverse products sucked by the reverse suction cup 420, and the positive products and reverse products are distributed vertically staggered, ensuring that the second suction cup structure 400 can smoothly put the product 100 into the packing box 600 and avoiding the interference between the product 100 on the outer circle and the packing box 600 when the second suction cup structure 400 puts the product 100 into the packing box 600. After the product 100 is put into the packing box 600, the positive products automatically move downward under the action of their own weight, so that the products 100 on the same layer can spread out and cover the packing box 600.

[0051] It can be understood that the first air path structure communicated with the pre - pickup suction cup 310, the second air path structure communicated with the positive suction cup 410, and the third air path structure communicated with the reverse suction cup 420 refer to the prior art.

[0052] It can be understood that the vertical driving structure for driving the second suction cup structure 400 to lift can also adopt other suitable driving structures, such as the structure driven by a motor through a conveyor belt, etc.
