Description

Technical Field

[0001] The present invention belongs to the technical field of plastic container material receiving and conveying equipment, and in particular relates to a multi-row limited stacking box and an alternating material receiving and conveying device thereof. Background Art

[0002] Disposable plastic tableware for daily use, such as disposable cups, bowls, boxes, lids and other container products, has two main methods for producing such disposable plastic tableware and supermarket fruit and vegetable packaging in the existing technology. The main method is to use sheet thermoforming. However, due to the different usage and purpose of cups, bowls, boxes and lids, their shapes are different. The traditional method is to place the formed products directly on the conveyor belt for transmission. However, the transmission is only placed on the conveyor belt, resulting in products that cannot stand on their own and cannot be transported. Also, due to the conveying structure connected behind the conveyor belt, the formed mold cavity is misaligned. In addition, there is no limit on the stacking height, resulting in any stacking height being too low. In order to meet the connection to the back-end transmission, a single row is required. The number of reciprocating times is too much to keep up with the discharge speed of the front and cannot be transported and boxed. In particular, the lid is made of thin and light material. If the stacking height is not high enough for each mold, it will be scattered and cannot be transported. Manual material collection and boxing is forced, which is labor-intensive and labor-intensive, with high labor costs, and it is even more impossible to transport smoothly. To complete the bagging, or to transport and pack, as of 2020, although the inventor has invented a double-box alternate transmission, and each mold and each cavity placement point also has a limit seat, except for the cover stacking, other containers can basically complete the stacking, conveying and packing operations, but for the lids with lighter materials, they must be stacked to a height that meets the packing speed requirements, and there is still a problem that the stacking height is too low and the number of round trips increases, which cannot meet the fast discharge speed in the front and the too low stacking and too many round trips in the back due to each mold and each cavity cannot correspond to the conveying and packing speed in the back. In addition, for some places with smaller installation positions, especially the material splicing and conveying device connecting three stations, the existing technology, including the replacement splicing and conveying device invented by me before, cannot meet the installation of the above-mentioned spatial position. In summary, the problem of studying multiple rows of limited stacking boxes and configuring an alternating conveying device to carry multiple rows of limited stacking boxes subverts the disclosed traditional technology on the problem of lid stacking and solves the above-mentioned problems that need to be solved in the industry.

[0016] The present invention has the following beneficial effects:

[0017] (1) A detachable stacking material box is used, so that the corresponding cover body and single-row limiting stacking piece can be selected according to the actual products to be produced, so that it can quickly adapt to the conveying and stacking of different products. Through the multi-row setting of single-row limiting stacking pieces, it can accurately correspond to the container or cover formed each time, so that the products made in each mold can be directly stored, and through the setting of the limiting rod, it can be stacked synchronously during the storage process;

[0018] (2) By lifting and lowering the docking plate and the limiting rod, the products can be stacked in a limited manner. At the same time, in the next process, after the products on the single-row limiting splicing piece are completely taken out, the limiting rod and the splicing port on the single-row limiting splicing piece can be hidden in the splicing box in time, so as not to affect the products on the next row of single-row limiting splicing pieces and cause obstruction, thereby facilitating the transfer of products in each row.

[0019] (3) The upper and lower stacking boxes are alternately transported by the cooperation of the upper and lower translation rails, and the stacking box is lifted by the lifting structure so that it can be at the same height as the stacking box on the upper translation rail, which is convenient for storing and stacking the products;

[0020] (4) Both the upper and lower translation structures adopt three-level horizontal movement, which greatly increases the transmission speed, so that it can meet the various processes of receiving, transmitting and unloading materials. In addition, the structure is simple and can be directly used with the existing cup making machine, and the modification cost is low.

[0021] (5) The online sampling function is convenient and fast, and the quality is more guaranteed.

[0022] (6) The upper and lower translation structures of this device cooperate with the lower translation lifting structure to minimize the width of the floor space, and the required appropriate height can be adjusted to configure any cup making machine for high-speed transmission, especially more suitable for connecting three-station lid making, limited splicing, high-speed transmission and box sealing production lines.

[0023] (7) The lower translation lifting structure avoids the installation of the driving spindle and the driving source on the lifting base, especially by utilizing the gap space around the stacking material box, setting up a rectangular lifting shaft structure, connecting the lower translation structure with the flying plates on both sides of the lifting base, setting up the lifting support platform on both sides of the lifting shaft higher than the translation support, installing the first lifting seat, and installing the second lifting seat with the lifting brackets on both sides of the first lifting seat, so that both sides of the second lifting seat after lifting can avoid the movement space of the conveying and stacking robot, and effectively utilizing the height of the stacking material box and the stacking height of the products, so that the stacking material box and the lower translation lifting structure are installed on the lower translation structure and the installation height is lower than the lifting stroke when stored, achieving the beneficial effect of forming effective isolation with the upper translation mechanism and not affecting each other.

[0024] (8) The limit rod can achieve the high-speed stacking requirements of containers or lids of different shapes and thicknesses, products that cannot be placed independently, and even products with staggered mold arrangements. At the same time, it can also limit the height requirements of box conveying, and with the cooperation of the alternating conveying device, any product that can be formed by the thermoforming machine can be stored and stacked on the receiving port of the receiving plate, thus subverting the traditional technology.

[0039] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0040] A multi-row limited stacking box 100 according to an embodiment of the present invention is as follows Figures 3-5As shown, it includes a box body 101 and a cover body 102, and the cover body 102 covers the top of the box body 101, and also includes a plurality of groups of single-row limiting splices 103 arranged in parallel and adjacent to each other in the box body 101. The upper surface of the cover body 102 is provided with a lifting window for the single-row limiting splices 103 to extend out of the outside world. The single-row limiting splices 103 include a mounting seat 104, a material receiving and lifting driver 105, a material receiving and lifting plate 106, a limiting lifting driver 107, a limiting lifting plate 108 and a material receiving plate 109. A plurality of protrusions 110 are provided in parallel on the material receiving plate 109, and each adjacent two protrusions 110 are spaced apart from each other to form a concave-convex material receiving port 111, and the material receiving plate 109 is connected to the material receiving port through the material receiving port. The connecting rod 112 is fixed on the material receiving lifting plate 106, the material receiving lifting driver 105 is fixed on the lower surface of the mounting seat 104 and passes through the mounting seat 104 to push the material receiving lifting plate 106 to move up and down, the limiting lifting driver 107 is fixed below the material receiving lifting plate 106 to avoid the position of the material receiving lifting driver 105 and passes through the material receiving lifting plate 106 to push the limiting lifting plate 108, and the limiting lifting plate 108 is provided with a plurality of limiting rods 113 matching the material receiving port 111, and the limiting rods 113 are slidably arranged in the protrusion 110, and the mounting seat 104 is fixed to the bottom of the box body 101 or fixedly arranged under the cover body 102 through a mounting piece. The receiving plate 109 can be directly lowered into the box body 101, and the standard for its completion of lowering is that the top of the protrusion 110 is just immersed in the upper surface of the cover body 102. At this time, when the receiving plate 109 of the front single-row limiting splicing piece 103 is completely hidden in the box body 101, the receiving port 111 of the other single-row limiting splicing piece 103 at the back can be completely exposed, which is convenient for the subsequent transfer robot to transfer the products stacked on each single-row limiting splicing piece 103 row by row. When the product is limited by the limiting rod 113 and falls, it will directly hang on the top of the protrusion 110 through the edge, so that the receiving port 111 at the bottom of the receiving port 111 is left empty, so that the subsequent transfer robot can support the bottom of the product through the receiving port 111 when grabbing the product, thereby ensuring that the robot maintains sufficient support force on the top and bottom of the product during transfer, thereby ensuring stable and fast rotation of the product.

[0041] Specifically, an auxiliary lifting driver 114 and a limiting rod fixing seat 115 are provided between the material receiving lifting plate 106 and the limiting lifting plate 108. The auxiliary lifting driver 114 is fixed to the lower surface of the limiting rod fixing seat 115 and passes through the limiting rod fixing seat 115 to push the limiting lifting plate 108 to move up and down. The limiting lifting driver 107 pushes the limiting rod fixing seat 115 to move up and down. The limiting lifting plate 108 is used to control the position of the limiting rod 113 and ensure that the limiting rod 113 can be quickly retracted when the product is transferred by the transfer robot, thereby not affecting the transfer robot's rapid transfer of the product. The dual-stage lifting setting can ensure that the limiting rod 113 can be raised and lowered at a faster speed and the lifting stroke of the limiting rod 113 can be guaranteed, thereby ensuring that it can be limited even when receiving tall cups, meeting the stacking requirements.

[0042] Furthermore, at least two limiting slide bars 116 are symmetrically provided between the limiting rod fixing seat 115 and the limiting lifting plate 108, and the limiting slide bars 116 are fixed to the lower surface of the limiting lifting plate 108 and are slidably provided in the limiting sliding sleeve 117 on the limiting rod fixing seat 115, and at least two auxiliary slide bars 118 are symmetrically provided between the material receiving lifting plate and the limiting rod fixing seat 115, and the auxiliary slide bars 118 are fixed to the lower surface of the limiting rod fixing seat 115 and are slidably provided in the limiting sliding sleeve 117 on the limiting rod fixing seat 115. At least two material receiving slides 120 are symmetrically positioned within the auxiliary sleeve 119 on the material receiving lift plate 106, between the mounting base 104 and the material receiving lift plate 106. These slides 120 are secured to the lower surface of the material receiving lift plate 106 and slide within sleeves 121 on the mounting base 104. Both the material receiving lift plate 106 and the mounting base 104 are provided with through-holes for accommodating corresponding components, allowing the movement of the components of the single-row limited splicing element 103 to proceed independently of each other. All lifts are independent and mirror-imaged, ensuring support stability and quick and convenient operation.

[0043] This embodiment also provides an alternate material receiving and conveying device such as Figure 1-7As shown, it includes a conveying bracket 200, and an upper translation rail 201 and a lower translation rail 202 are provided on the conveying bracket 200.

The upper translation structure 300 and the lower translation structure 400 are both placed with the above-mentioned multi-row limit stacking material boxes 100. When the lower translation structure 400 drives the multi-row limit stacking material boxes 100 to slide horizontally, the sliding of the upper translation structure 300 on the upper translation rail 201 is staggered, and the lower translation structure 400 and the multi-row limit stacking material boxes thereon are staggered. A lower translation lifting structure 500 is provided in the middle of the material box 100. The lower translation lifting structure 500 is used to lift the multi-row limited stacking material box 100 placed on the lower translation structure 400 to the corresponding stacking station A. The horizontal position of the multi-row limited stacking material box 100 on the upper translation structure 300 is at the same horizontal position as the stacking station A. It also includes a sampling structure, which is arranged on the side of the conveying bracket 200 and matches the sampling station B of the conveying bracket 200. Specifically, the sampling structure includes a sampling bracket, on which the multi-row limited stacking material box 100 is placed, and the sampling bracket is fixed or adjacent to the conveying bracket 200. The alternating material splicing and conveying device is mainly arranged in conjunction with the multi-row limited stacking material box 100. By alternating material splicing, it is ensured that the upper and lower multi-row limited stacking material boxes 100 can alternately splice materials when splicing, thereby achieving uninterrupted operation. At the same time, it is equipped with a random inspection structure, which can conduct random inspections on the products in this step, so as to quickly understand the quality of the products coming out of the cup making machine, avoid testing the products until the subsequent packing, and effectively suppress the defective rate.

[0044] Specifically, the upper translation structure 300 includes an upper main slider 301, an upper translation platform 302, an upper slide group and an upper second slide group.

The lower sliding motor 204 drives the lower synchronous belt to drive the lower main slider 401 and the lower translation platform 402 to slide. The next slide group and the lower second slide group are slid and stacked in the lower translation platform 402 in turn. The lower translation lifting structure 500 is fixed on the lower second slide group and is driven by the lower second slide group.

[0047] Furthermore, the next slide group includes two groups of next sliders 403, a lower push cylinder 404 and a next translation platform 405. The two groups of the next sliders 403 are respectively fixed on both sides of the lower translation platform 402. The next translation platform 405 is slidably mounted on the next slider 403 through a next slide rail 406 arranged on the lower surface. A push block 408 is arranged on the side of the next translation platform 405. The two groups of the lower push cylinders 404 are fixed on both sides of the lower translation platform 402 and push the lower push cylinders 404 arranged on the lower translation platform 402.

The lower second slide group includes lower second sliders 409 and lower second slide motors 410. The lower second sliders 409 are slidably mounted on the lower second slide rails 407 on the upper surface of the next translation platform 405. The lower second slide motors 410 are fixed to the side of the next translation platform 405 and drive the lower second sliders 409 to slide via a synchronous belt. The lower second sliders 409 are fixed to the bottom of the lower translation lifting structure 500. Both the upper translation structure 300 and the lower translation structure 400 adopt a three-stage horizontal translation design, which can ensure faster transportation, thereby enabling the multi-row limited stacking bins 100 to be quickly moved to the corresponding unloading station C or inspection station for unloading operations or corresponding inspection and sampling operations.

[0048] Preferably, the lower translation lifting structure 500 is configured to be a lifting shaft structure that is convenient for accommodating the multiple rows of limited stacking boxes 100 and driving the translation, and the next translation platform 405 is configured to be a lifting shaft structure that matches the lower translation lifting structure 500 and can accommodate the lower translation lifting structure 500 for translation, including a lifting base 501, a first lifting seat 504 and a second lifting seat 508, the second lifting seat 508 is nested in the first lifting seat 504, the first lifting seat 504 is accommodated in the lifting base 501, the lower two sliders 409 are fixed under the flying plates 502 on both sides of the lifting base 501, and the lifting base 501 is not provided with a flying plate 502 on both sides thereof.

The bar 505 is nested in the lifting support platform 503 and supports the first lifting seat 504. A first lifting driver 506 is provided on one side of the lifting support platform 503. The first lifting driver 506 drives the lifting gear shaft 507 through a synchronous belt. The lifting gear shaft 507 simultaneously drives the first lifting tooth bar 505 in the lifting support platforms 503 on both sides to drive the lifting of the first lifting seat 504. A second lifting driver 509 is fixed on the side of the first lifting seat 504. The second lifting driver 509 drives the second lifting tooth bar 510 which is arranged on both sides of the second lifting seat 508 and is immersed in the side wall of the first lifting seat 504. The second lifting tooth bar 510 drives the second lifting seat 508 to lift and lower. The multi-row limited stacking box 100 is placed in the second lifting seat 508. A three-stage lifting method is used to quickly lift the multi-row limited stacking bins 100 on the lower translation structure 400. The lifting is performed using a lifting tooth bar. The interlocking force between the lifting tooth bar and the gear ensures stable support for the multi-row limited stacking bins 100 during the rapid lifting process, effectively ensuring the stability of the material splicing. The fly plate 502 cooperates with the lower two sliders 409 to form a two-stage independent sliding structure, effectively shortening the translation stroke.
