Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a modular flexible packaging system. Background Art

[0002] Many products need to be packed after production. Currently, products are produced in an assembly line mode, and then packed through a subsequent automatic packaging assembly line. For example, boxed milk and beverages are usually packed directly by robots or robots after arranging the beverages. Common packaging systems pack products directly after arranging them, which results in the entire packaging system being a complete and indivisible production line. This places high demands on the site, and there must be a large enough space to accommodate the complete packaging system, which is greatly limited by space. In addition, each workstation in the packaging system is closely coordinated. As long as any workstation fails or waits, the entire packaging system needs to be shut down and wait. Summary of the invention

[0003] In order to solve the above problems existing in the packaging system in the prior art, the present invention provides a modular flexible packaging system which can be installed in a modular manner, has little space restriction, is flexible to install, and each module can work independently.

A flexible docking conveying platform is arranged between the conveying platform module and the packing platform module. A bottom support circulation conveying system is arranged inside the conveying platform module and the packing platform module. A plurality of bottom supports are arranged on the bottom support circulation conveying system. The bottom support conveying systems are connected via a flexible docking conveying platform. The conveying platform module comprises a material conveyor belt, a feed sorting mechanism, a sorting and positioning mechanism, and a material grabbing and transferring mechanism. A box feed conveyor belt and a packing mechanism are arranged inside the packing platform module.

[0006] The conveying platform module and the packing platform module are divided into two independent modules, which are connected by a flexible docking conveying platform. The conveying platform module and the packing platform module can be installed independently according to the site environment, and then the two are connected by a flexible docking conveying platform. The installation is more flexible and less restricted by the site space; the products to be packaged enter the feed sorting mechanism after passing through the material conveyor belt, and after being divided into multiple columns of products, the products are arranged into a regular array and positioned by the sorting and positioning mechanism, and then the product array is grabbed by the material grabbing and transferring mechanism and transferred to the bottom tray in the bottom tray circulation conveying system. The bottom tray loaded with the product is transported to the packing platform module through the flexible docking conveying platform. The packaging box is transported on the box feeding conveyor belt, and the packing mechanism grabs the product array in the bottom tray and puts it into the packaging box; this packaging system divides the entire packaging production line into two parts, and adds product positioning and storage links through the bottom tray. The products on the bottom tray can be stored and circulated separately, so that the conveying platform module and the packing platform module can work independently. Even if the packing platform module fails, the conveying platform module can store the products in the bottom tray and then store them in the flexible docking conveying platform. At the same time, the flexible docking conveying platform can also buffer and adjust the production rhythm of the conveying platform module and the packing platform module, making the entire packaging operation more mobile and flexible.

[0007] Preferably, the bottom support circulation conveying system comprises a bottom support front conveyor belt, a bottom support rear conveyor belt, a bottom support front circulation belt, and a bottom support rear circulation belt. The front ends of the bottom support front conveyor belt and the bottom support front circulation belt are connected by an arc-shaped front conveyor belt, and the rear ends of the bottom support rear conveyor belt and the bottom support rear circulation belt are connected by an arc-shaped rear conveyor belt. The rear end of the bottom support front conveyor belt and the front end of the bottom support rear conveyor belt are both docked with a flexible docking conveying platform, and the rear end of the bottom support front circulation belt and the front end of the bottom support rear circulation belt are both docked with the flexible docking conveying platform. The bottom support is circulated in the bottom support circulation conveying system.

[0008] As a preferred embodiment, the feed separation mechanism is arranged at the front end of the material conveyor belt, and the feed separation mechanism includes a front connecting bracket and a rear connecting bracket fixed on both sides of the material conveyor belt, a front slide bar is arranged between the front connecting brackets, and two parallel front slide bars are arranged on the front slide bar, and the lower end of each front slide bar is fixed with a front connecting seat, and a rear slide bar is arranged between the rear connecting brackets, and two parallel rear slide bars are arranged on the rear slide bar, and the lower end of each rear slide bar is fixed with a rear connecting seat, and the front connecting seat and the rear connecting seat are connected one by one through two flexible baffles, and a feed channel is formed between the two flexible baffles, and the rear connecting bracket is provided with a first motor for driving the two rear slide bars to slide synchronously in the same direction; and a plurality of parallel partitions are arranged at the rear end of the feed channel on the material conveyor belt, and a separation channel is formed between two adjacent partitions. The initial product enters in a row from the feed channel, and the first drive motor drives the rear slide bar to move along the rear slide bar, so that the rear end of the feed channel is respectively docked with different separation channels, so as to transport the product to different channels.

[0009] Preferably, a width adjustment mechanism is provided between the two front slides, and the width adjustment mechanism includes an adjustment rod, one end of which is rotatably connected to one front slide, and the other end of which passes through the other front slide and is threadedly connected to the front slide, and an adjustment handle is provided at the end of the adjustment rod; the width adjustment mechanism is also provided between the two rear slides. Different models of products have different length and width dimensions, and the width of the feed channel can be adjusted through the width adjustment mechanism, which has strong versatility.

[0010] Preferably, the inner sides of the front connecting seat and the rear connecting seat are provided with transmission wheels, a side conveyor belt is provided between the transmission wheels, and the ends of the front connecting seat and the rear connecting seat are provided with a second motor for driving the side conveyor belt to move. The corresponding position of the bottom of the front connecting seat and the rear connecting seat is exactly the butt joint of the two conveyor belts, and the transmission wheels and the side conveyor belts ensure that the product can be stably moved from one conveyor belt to another.

[0011] Preferably, the arranging and positioning mechanism is located at the rear end of the feed sorting mechanism, and the sorting mechanism includes slide rails parallelly distributed on both sides of the rear end of the material conveyor belt, a slider is provided on the slide rail, a material baffle is provided between the upper ends of the slider, a third motor for driving the slider to move along the slide rail is provided on the side of the material conveyor belt, and a lifting mechanism for driving the material baffle to rise and fall is also provided on the slider; a plurality of groups of isolation bars are provided on the top surface of the rear end of the material conveyor belt, each group of isolation bars has two, and a limiting channel is formed between each group of isolation bars, and a limiting member is provided in the limiting channel.

[0014] Preferably, the flexible docking conveying platform is any one of a linear conveying platform, an L-shaped conveying platform, a U-shaped conveying platform, and a lifting conveying platform. When the conveying platform module and the packing platform module are located on the same horizontal plane and are distributed in a straight line, a linear conveying platform can be selected; when the conveying platform module and the packing platform module are distributed vertically, an L-shaped conveying platform can be selected; when the conveying platform module and the packing platform module are distributed side by side, a U-shaped conveying platform can be selected; when the conveying platform module and the packing platform module are distributed in leap layers, a lifting conveying platform can be selected; the above-mentioned conveying platforms can also be combined and used according to actual needs, or other flexible docking conveying platforms can be used to match the site space requirements.

[0015] Preferably, the front circulating belt of the bottom support is located below the material conveyor belt. The front circulating belt of the bottom support is hidden below the material conveyor belt, thereby making the whole more compact and reducing the occupied space.

[0016] Therefore, the present invention has the following beneficial effects: (1) the overall packaging system is divided into a conveying platform module and a packing platform module. The two modules can be independently installed according to the spatial layout of the installation site, and finally connected through a flexible docking conveying platform. The space restriction is small and the installation is more flexible. (2) a bottom tray circulation conveying system is set to transport the bottom tray, and the sorted product array is first transferred to the bottom tray to form an intermediate product, and then the intermediate product is subsequently packed, that is, a packing operation is decomposed into two steps, so that the dependence between product positioning and product packing operations is reduced. The flexible docking conveying platform forms a buffer and storage area to buffer and adjust the production rhythm between the conveying platform module and the packing platform module. The conveying platform module and the packing platform module can operate relatively independently. For example, when the packing platform module fails and needs to be repaired, the conveying platform module can continue to work, transfer the sorted product array to the bottom tray and store it in the flexible docking conveying platform.
