Description

Technical Field

[0001] The invention relates to the technical field related to the transmission of disposable plastic containers, and in particular to an AB unit multi-directional sliding alternating material receiving and conveying device. Background Art

[0002] Disposable plastic tableware for daily use, such as disposable cups, bowls, plates, lids, boxes and other container products, are mainly produced in two ways in the prior art. The first is injection molding. Although the raw materials can be fully utilized without corners, injection molding has problems such as expensive molds, long mold processing and debugging cycles, and easy loss of market opportunities. In addition, the number and speed of each mold in injection molding cannot be compared with sheet air pressure thermoforming cup making machines. The second way is to use the upper and lower pressing cup making machines and flip molded cup making machines and three-station or four-station thermoforming production lines to produce products. In particular, the pure cup production has a pure color and no pattern, and the product grade is low. Even if the product is printed on a curved surface, the clarity and texture of the product image cannot be compared with injection molding or in-mold labeling. In addition, the existing domestic and foreign technologies have not yet achieved high-speed material receiving and transmission on the receiving device to meet the requirements of the products produced by the above-mentioned various models. Moreover, the in-mold labeling production line of the prior art has as many as eleven actions per mold and requires the use of additional in-mold labeling robots. The cup-making and stacking conveying robots alone need to perform several actions per mold. For example, the in-mold labeling robot must first wait for the unloading robot to descend and vacate a position before it can perform four actions: translation entry, descending to place labels, ascending and translation exit. That is, the in-mold labeling robot connected to the traditional flip mold requires nine actions to complete the production of one mold product, while the connection to the upper and lower pressing thermoforming cup-making machine requires eleven actions to complete. Whether it is connecting the flip mold or the upper and lower pressing for in-mold labeling, the traditional in-mold labeling technology still has many actions and low efficiency. How to realize cup-making mold technology that can utilize existing cup-making machines and is conducive to streamlining production line operations and high work efficiency has become a research hotspot in this industry. How to realize the connection of upper and lower pressing cup-making machines, flip molding cup-making machines, three-station cup-making machines and other units or production lines, and how to realize the material receiving, conveying and packaging technology of containers of multiple specifications and shapes of the above equipment, including lids and staggered products in the same device, is a key problem that needs to be solved.

[0020] Beneficial effects of the present invention:

[0021] 1. The present invention is provided with a two-stage longitudinal drive and transverse telescopic drive mechanism to realize the multi-directional sliding movement of the receiving tray. The transverse telescopic sliding components of the two groups of stacking units collide with each other when they are staggered vertically and horizontally translated, and the space is cleverly utilized to realize joint movement in a limited space. The multi-directional movement of the receiving tray can realize the alternating operation and work of the receiving trays of the two groups of stacking units, and the receiving station, unloading station and sampling station can be alternately shared.

[0022] 2. The two sets of stacking units of the present invention are arranged side by side to achieve multi-stage telescopic longitudinal and lateral translation, so that they can be docked with different manipulators and applied to various transmission units.

[0023] 3. The receiving tray of the present invention can be detachably mounted on the mounting plate, so that the receiving tray can be replaced at any time as needed, so that it can be suitable for products of various specifications and sizes, such as cups, bowls, plates, trays and lids, and the product placement position of the receiving tray is set to correspond to the receiving and unloading link structure required by the front and rear robot devices of the production line to achieve smooth transfer, thereby achieving high work efficiency.

[0024] 4. For products that are too short to be received by the cup shoulder or cup edge (short cups, plates and lids, etc.), the receiving tray of the present invention is provided with a tray body and at least one single-row receiving rack, each single-row receiving rack is provided with a plurality of protrusions, and a fork position groove is formed between two adjacent protrusions. The protrusions and the fork position groove have a concave-convex structure, which facilitates the robot to insert into the fork position groove to clamp the bottom and upper part of the product, so as to realize the stacking and receiving and conveying of products without cup shoulders or cup edges and lids.

[0025] 5. For products that are misaligned and have a short body that cannot be connected with the cup shoulder or cup edge, the receiving tray of the present invention, in addition to the first single-row support frame, the subsequent single-row support frames are each equipped with an independent lifting drive device, and the single-row support frames are driven to rise and fall by the independent lifting drive device. Utilizing the independent lifting of the front row receiving support frames, it is achieved that when the receiving material is lowered and translated forked in, the robot does not collide with the rear row receiving support frames that have completed unloading.

[0027] 7. The receiving tray of the present invention can be replaced and moved in multiple directions. Corresponding receiving trays are provided for conventional cups, short products and special-shaped cups. Therefore, the AB unit multi-directional sliding alternating receiving and conveying device of the present invention can be used for in-mold labeling and packing production lines, three-station thermoforming machines, and upper and lower pressing and flipping molded cup machines to cooperate with the manipulator to receive various products produced by them and stack and convey them, solving the technical problem of how to automatically receive and convey materials, which is urgently needed in the industry, and greatly improving production efficiency and reducing labor costs. At the same time, it can meet the product conveyance of in-mold labeling and packing production lines at home and abroad, including the product conveyance of in-mold labeling cup conveying and packing production lines connected to their special receiving and conveying for white cups.

[0028] 8.

DETAILED DESCRIPTION

[0048] The present invention will be further described with reference to the following examples. Example 1

[0049] Referring to the attached drawings, the AB unit multi-directional sliding alternating material receiving and conveying device of this embodiment is provided with two groups of stacking units, which can be divided into A unit and B unit, and A unit and B unit work alternately. Each group of stacking units includes a receiving tray 1, a primary driving mechanism and a secondary driving mechanism, and the primary driving mechanism includes a mounting plate 2-1, a primary sliding block 2-2, a primary guide rail 2-3, a primary driving device 2-4 and a primary supporting platform 2-5. The receiving tray 1 can be detachably mounted on the mounting plate 2-1, so that different receiving trays 1 can be conveniently replaced to be suitable for stacking products of different specifications and cup shapes. Among them, the bottom of the mounting plate 2-1 is fixed with a primary slider 2-2, the primary slider 2-2 is slidably arranged on the primary guide rail 2-3, the primary guide rail 2-3 is fixed to the primary support platform 2-5, and the mounting plate 2-1 is driven to translate by a primary driving mechanism, wherein the primary driving device 2-4 can be composed of a motor, a transmission wheel, a transmission shaft and a transmission belt, and the connection method of the motor, the transmission wheel, the transmission shaft and the transmission belt is conventional technology and will not be repeated here. It should be noted that the primary driving device 2-4 can also be set as an electric screw, a cylinder or other equipment that can drive the primary support plate to translate, all of which belong to the scope of protection required by the present invention. In this embodiment, the primary driving device 2-4 is set as a cylinder. The secondary driving mechanism of this embodiment has a connecting component, a secondary driving device 3-1 and a support frame 3-2, the secondary driving device 3-1 is installed on the support frame 3-2, and the secondary driving device 3-1 drives the primary support platform 2-5 to translate through the connecting component. Among them, the connecting component can be any structure that can realize the connection between the secondary driving device 3-1 and the primary support platform 2-5. The present invention configures a driving source through multiple different sliding rails, and cleverly uses the common motion space by staggering the telescopic and high and low installation positions, so that the receiving trays 1 of the two stacking units can replace the common receiving station, unloading station and sampling station. At the same time, the two stacking units are arranged side by side to achieve multi-stage telescopic longitudinal translation, so that different equipment groups can be connected. The present invention can replace the receiving tray 1 at any time according to needs, so that it can be suitable for products of various specifications and sizes, such as cups, bowls, plates, plates and lids.

[0050] The AB unit multi-directional sliding alternating material receiving and conveying device of the present invention can be used for in-mold labeling and packaging production lines, three-station thermoforming machines, and upper and lower pressing and flipping molded cup machines and other equipment to cooperate with the robot to receive the products produced by them and stack and convey them, solving the technical problem of how to automatically receive and convey materials that the industry urgently needs to solve, and greatly improving production efficiency and reducing labor costs.

[0051] Different receiving trays 1 can be set for different cup types. The receiving tray 1 is provided with a tray body, a bottom plate 1-3 and a receiving platform 1-2. The receiving platform 1-2 is installed on the upper part of the tray body and is provided with a plurality of receiving holes 1-21. The bottom plate 1-3 is installed on the tray body. The side plates at both ends of the tray body are provided with adjustment holes 1-4. Bolts can pass through the adjustment holes 1-4 to connect with the bottom plate 1-3. Therefore, the receiving tray 1 can be replaced at any time according to the needs, so that it can be suitable for products of various specifications and sizes, such as cups, bowls, plates, plates and lids. Moreover, the product placement position of the receiving tray 1 is set to correspond to the receiving and unloading link structure required by the front and rear manipulator devices of the production line to achieve smooth transmission, and high work efficiency. The material receiving side of the AB unit multi-directional sliding alternating material receiving and conveying device of this embodiment is connected to the multi-functional material loading and unloading conveying robot C of the production line to stack a certain amount of products, and the material discharging side of the AB unit multi-directional sliding alternating material receiving and conveying device is connected to the material receiving transfer conveying robot E of the production line. The material receiving transfer conveying robot E clamps a certain amount of stacked products from the material receiving tray and conveys them to the next equipment. The two material receiving trays work alternately. When one material receiving tray receives materials from the multi-functional material loading and unloading conveying robot C, the material receiving transfer conveying robot E takes materials from the other material receiving tray.

[0052] For products whose lids and diameters are greater than their heights and which cannot be picked up by the rim of the cup, it is necessary to use a fork to support the bottom to pick up the materials before transferring them to the next device. However, the traditional technology only pushes the materials in a horizontal direction. The bottom of the inner cavity of the traditional receiving tray 1 is set to be flat, but it cannot cooperate with the receiving fork of the single-row receiving and transfer device to transfer materials, because the single-row receiving and transfer device cannot reach into the bottom of the products from the traditional receiving tray 1 to clamp the stacked products. In order to meet the needs of smooth sliding unloading and the need for the single-row receiving and transfer robot E to insert the receiving fork of the material picking device to rise and pick up the materials, the present invention has a special concave convex shape to achieve the needs of smooth sliding to meet the needs of unloading and smooth forking into the products to rise and pick up the materials and transfer them to the next receiving and transfer device. Moreover, in order to connect the finished product receiving device of the thermoforming machine to realize the process from receiving and conveying to packing, the production efficiency is improved. For the receiving of normal cup-shaped or tall cup-shaped products that are not misplaced, the receiving tray 1 is provided with multiple parallel receiving troughs 1-5, and a limiting partition wall 1-6 is provided between two adjacent receiving troughs 1-5. This structure can make the whole tray of multiple rows of stacked products on the receiving tray 1 be directly and neatly pushed by the pushing device to the conveyor belt for direct transmission (the pushing device and the conveyor belt are other equipment of the production line and do not belong to the AB unit multi-directional sliding alternating receiving and conveying device of the present invention). Due to the existence of the limiting partition wall 1-6, the direct pushing of the products will not collapse, but multiple rows of products can be directly pushed to the conveyor belt, which greatly improves the work efficiency. For short products that are not misplaced, a convex groove 1-7 can be provided in the aforementioned receiving trough 1-5. The groove 1-7 allows the fork of the transfer conveying robot E to extend into and press the whole row up and down together for clamping and transmission.

[0053] For ordinary cup-shaped products or tall products with cup rims, the receiving tray 1 is provided with a tray body and a plurality of single-row receiving racks, each of which is provided with a plurality of protrusions 1-3' forming fork slots 1-4'. The protrusions 1-3' and the fork slots have a concave-convex structure, which facilitates the robot to insert into the fork slots to clamp the bottom and top of the product to achieve stacking and receiving and conveying of products without cup shoulders or cup rims and lids. The robot is other equipment of the production line and does not belong to the protection scope of the present invention, but it shares the function of partially conveying the product in the production line with the AB unit multi-directional sliding alternating receiving and conveying device of the present invention. The structure and function of the robot can refer to the patent document of container and lid transfer conveying robot E with publication number CN108974445A. In order to place the product more stably, a cup mold 1-5' is provided on the top of the protrusion 1-3' of the receiving tray 1 of this embodiment. The inner curvature of the cup mold 1-5' is the same as the curvature of the outer wall contact portion of the product. The two cup molds 1-5' opposite to the two adjacent protrusions 1-3' are arranged relative to each other to hold the product. The cup mold 1-5' can be made by cutting the product. The cup mold 1-5' arranged in this way has low cost, simple operation and high fit. The translation support drive unit of this embodiment is composed of a motor, a rotating shaft, a transmission wheel and a synchronous belt, and the synchronous belt is connected to the connecting platform through a connecting piece.

[0054] The AB unit multi-directional sliding alternating material receiving and conveying device of the present invention can realize high-speed material receiving and conveying, meet the speed requirements of the upper and lower pressing thermoforming machine, the flip molding cup machine and the thermoforming production line, and can also cooperate with the multifunctional material receiving and conveying robot and the single-row material receiving and transferring conveying robot EE to lay the foundation for the smooth operation of the multifunctional six-action in-mold labeling conveying and packing production line. This device connects all the products of various specifications and shapes of the above-mentioned various machines and equipment and the material receiving and conveying of the staggered rows, including changing the material receiving and conveying mode of the white cup special mode and the in-mold labeling special mode to make it more compressed, reduce the number of actions and increase the running speed, and realize convenient and quick use and replacement, and at the same time realize the affixing of rich labels with pictures and texts while producing and preparing products, greatly improving the aesthetics of the products and increasing the added value of the products.

[0055] The primary drive device 2-4, the secondary drive device 3-1 and the transverse drive device can be cylinders, electric screws or composed of motors and transmission components. The structure and principle of such drive devices are all prior art and should be clearly understood by those skilled in the art without detailed description. In order to obtain the smallest volume, smooth and high-speed movement, in this embodiment, the two-stage drive of the primary drive device 2-4 and the transverse drive device are cylinders, and the secondary drive device 3-1 is composed of a motor, a transmission shaft, a transmission wheel and a transmission belt. The structure, working principle and mode of the cylinder, motor, transmission shaft, transmission wheel and transmission belt are all prior art. It is unnecessary to elaborate on them. Those skilled in the art should be able to understand and implement the invention. In addition, the sliding pair mentioned in the present invention refers to a group of components with fixed parts and sliding parts, such as guide rails and sliders, slide rods and sliding sleeves in guide rails. The structure and working principle of the sliding pair also belong to the prior art and should be clearly understood by those skilled in the art.
