Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic bag packaging equipment, in particular to a multi-station plastic bag transfer device for transferring plastic bags from an initial position to multiple storage stations and achieving automatic switching of the storage stations and overturning and emptying operations of full storage stations. BACKGROUND

[0002] In the production, processing and packaging process of plastic bags, it is necessary to transfer the produced plastic bags to the designated storage position for subsequent packaging, transportation and sales. However, the existing plastic bag transfer technology has many problems and shortcomings, and it is difficult to meet the production demand of large scale and high efficiency.

[0003] Existing transfer methods and problems

[0004] 1. Manual transfer

[0005] Low efficiency: manual transfer of plastic bags is slow, especially in large-scale production scenarios, manual handling speed is far behind the production speed of plastic bags, resulting in production process obstruction and low production efficiency;

[0006] High labor intensity: long-time manual handling will make workers feel tired, increase labor intensity, easily cause industrial accidents, and also difficult to ensure the stability and accuracy of the transfer process;

[0007] High cost: manual transfer requires hiring a large number of labor, with the continuous rise of labor cost, the production cost of enterprises will also increase accordingly.

[0008] 2. Simple mechanical transfer equipment

[0009] Single function: some existing simple mechanical transfer equipment, such as conveyor belt, etc., can usually only realize the straight-line transportation of plastic bags in a single direction, and cannot complete the operation of accurately transporting plastic bags to multiple different storage stations and switching between different stations;

[0010] Lack of flexibility: the movement trajectory and transportation method of these devices are relatively fixed, and it is difficult to adjust flexibly according to actual production needs. When the production process changes or the storage station needs to be adjusted, the device cannot quickly adapt;

[0011] Cannot realize automatic emptying: when the storage station is full of plastic bags, manual operation is required to take down the full storage container and empty the plastic bags, which not only increases the labor cost, but also the emptying process is inefficient and prone to plastic bag spillage and other problems.

[0012] 3. Low automation

[0013] Dependence on manual operation: Although some existing transfer equipment has certain automation functions, manual intervention and operation are still required in the process of station switching and full material judgment, and full-process automation control cannot be achieved, which leads to the inability to further improve production efficiency. Practical new type content

[0014] The problem to be solved by the present application is the low efficiency, high labor intensity, high cost, single function, lack of flexibility and low automation degree in the existing plastic bag transfer technology.

[0016] Since the plastic bag transfer device of the present application is designed with a longitudinal driving mechanism and a selection driving mechanism, it can realize automatic and accurate transfer of plastic bags between different stations, automatic switching of storage stations, and automatic overturning and unloading when the storage rack is full, thereby improving the efficiency of plastic bag transfer and collection, reducing production cost and labor intensity, and solving the problems of low efficiency, high labor intensity, high cost, single function, lack of flexibility and low automation degree in the existing plastic bag transfer technology.

[0017] The technical scheme of the present application has the following effects compared with the prior art:

[0018] 1. Improve transfer efficiency: the present application realizes accurate transfer of plastic bags in three-dimensional space through the cooperative work of the horizontal driving mechanism, the longitudinal driving mechanism and the selection driving mechanism, which can quickly and accurately transport plastic bags from the transfer platform to different storage stations, greatly improving the transfer efficiency and meeting the needs of large-scale production;

[0019] 2. Reduce labor intensity: the device realizes full-process automation control, without the need for manual handling and operation, thereby reducing the labor intensity of workers and reducing the labor cost input;

[0020] 3. Enhance flexibility: the design of the transmission assembly enables the device to be flexibly adjusted according to different production needs and production processes, and the storage station can be easily switched to adapt to changes in various production scenarios;

[0021] 4. Automatic material unloading: The plastic bag storage rack is equipped with a tilting cylinder that enables automatic tilting and unloading of the rack, avoiding the inconvenience and inefficiency of manual unloading, improving the efficiency of plastic bag collection and processing, reducing the occurrence of plastic bag spillage, and ensuring product quality.

[0035] The selection driving mechanism 6 is used to drive the plastic bag transfer platform 2 to reciprocate between the multiple plastic bag storage racks 3 arrangement direction, so that the transverse platform is aligned with the multiple plastic bag storage racks 3 respectively, and the structure is as follows: a transverse platform is arranged with a linearly arranged selection track 61, the selection track 61 is made of high-strength aluminum alloy material, light in weight and high in strength, a selection belt 62 is arranged on the inner side of the selection track 61, which is made of special rubber composite material and has good wear resistance and tensile performance, a selection motor 63 is installed on the upper part of the transverse platform, the selection motor 63 and the selection belt 62 are connected by a key-connected pulley to realize power transmission, the plastic bag transfer platform 2 is arranged on the upper part of the selection belt 62 and is fixedly connected, the plastic bag transfer platform 2 is slidingly installed on the upper part of the selection track 61, when the selection motor 63 is started, the selection belt 62 is driven to rotate, the selection belt 62 drives the plastic bag transfer platform 2 to linearly reciprocate along the selection track 61 between the multiple plastic bag storage racks 3, so as to realize the alignment operation of the plastic bag transfer platform 2 and different plastic bag storage racks 3, so that when one of the plastic bag storage racks 3 is full of plastic bags, the plastic bag transfer platform 2 can perform plastic bag conveying operation on other idle plastic bag storage racks 3.

[0036] The plastic bag storage rack 3 is a longitudinally arranged frame structure and is vertically arranged in the conveying direction of the plastic bags, a turnover cylinder 31 is separately installed between the plastic bag storage rack 3 and the rack 1, and the lower side of the plastic bag storage rack 3 is rotationally installed on the rack 1, when the plastic bag storage rack 3 is full of plastic bags, the plastic bag storage rack 3 is driven by the turnover cylinder 31 to overturn around the rack 1, so as to concentrate and pour out the plastic bags stacked in the interior, thereby greatly improving the efficiency of plastic bag collection and processing.

[0037] Working principle: first, the plastic bags to be transferred are placed on the plastic bag transfer platform 2, the transverse driving mechanism 4 is started, the transverse motor 43 drives the transverse belt 42 to rotate, the transverse belt 42 drives the transverse platform to move along the transverse track 41 to the direction of the plastic bag storage rack 3, until the transverse platform moves above the target plastic bag storage rack 3, then the longitudinal driving mechanism 5 is started, the longitudinal motor 53 drives the gear to rotate, the gear is engaged with the longitudinal rack 52, and drives the longitudinal platform to move downward along the longitudinal track 51, so as to convey the plastic bags from the top of the rack to the bottom of the rack, when the plastic bag storage rack 3 is full, the selection driving mechanism 6 is started, the selection motor 63 drives the selection belt 62 to rotate, the selection belt 62 drives the plastic bag transfer platform 2 to move along the selection track 61, so that the plastic bag transfer platform 2 is aligned with the next idle plastic bag storage rack 3, and then the above-mentioned transverse and longitudinal movement is repeated to transfer the plastic bags to the new rack, when all the racks are full, the turnover cylinder 31 drives the full plastic bag storage rack to overturn, so as to pour out the plastic bags for subsequent collection and processing.

[0038] The use method is as follows: the plastic bags to be transported are placed on the plastic bag transportation platform 2 in an orderly manner, and the arrangement direction and quantity of the plastic bags are paid attention to, so as to avoid jamming or falling during the transportation process; the power supply of the horizontal motor 43 is connected; the parameters of the horizontal movement, such as the movement speed and target position, are set through the control system; the horizontal motor 43 is started to drive the horizontal belt 42 to rotate, and the horizontal platform moves along the horizontal rail 41 to the target plastic bag storage rack 3; in the movement process, the operator can monitor the movement state of the horizontal platform in real time through the observation window or the feedback information of the sensor; when the horizontal platform moves to the top of the target plastic bag storage rack 3, the horizontal motor 43 stops running, and the horizontal platform is accurately parked at the predetermined position above the storage rack; the power supply of the vertical motor 53 is connected; the parameters of the vertical movement, such as the descending depth and movement speed, are set; the vertical motor 53 is started to drive the vertical platform to move downward along the vertical rail 51 through the meshing transmission of the gear and the vertical rack 52; the vertical platform gradually transports the plastic bags from the top of the storage rack to the bottom of the storage rack; and when the predetermined position is reached, the vertical motor 53 stops running.
