Abstract
Description
Technical Field
[0001] This utility model relates to a workbench used in workshop production and assembly, and in particular a semi-automatic loading and unloading processing table. Background Technology
[0002] In traditional workshop production, when workers are producing and assembling products, additional turnover workers are needed to bring in semi-finished products to be processed and to retrieve finished products. This not only incurs additional labor costs, but also means that multiple workstations are often operating simultaneously in a particular process. For example, when installing a casing on a product, two or more workers may be installing the casing at the same time. However, due to differences in skill levels and processing speeds, turnover workers cannot effectively allocate the quantity of products. This can result in a large accumulation of semi-finished products at the workstations of workers with slower processing speeds, while the workstations of workers with faster processing speeds cannot replenish their inventory in a timely manner and need to be transferred from the workstations of workers with slower processing speeds, thus leading to repeated turnover. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a semi-automatic loading and unloading processing table.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A semi-automatic loading and unloading processing table includes a processing table, with a loading conveyor belt driven by a first motor and a unloading conveyor belt driven by a second motor installed at the rear of the processing table. The loading conveyor belt is connected to the incoming material conveyor belt of the production line, and the unloading conveyor belt is connected to the feeding conveyor belt of the production line. The loading conveyor belt has a loading port on the left side of the processing table, and a loading cylinder is installed on the loading conveyor belt corresponding to the loading port. The unloading conveyor belt has a unloading port on the right side of the processing table for feeding products onto the unloading conveyor belt.
[0006] A connecting belt is provided on the feeding port in the direction of the processing table, and the end of the connecting belt abuts against the processing table.
[0007] The top surface of the feeding conveyor belt is not lower than the top surface of the connecting belt, and the top surface of the connecting belt is not lower than the table surface of the processing table.
[0008] The unloading conveyor belt is located below the loading conveyor belt, and a downward-sloping sliding belt is provided on the right side of the processing table in the direction of the unloading conveyor belt, with the end of the sliding belt cooperating with the unloading port.
[0009] A second sensor is installed on the sliding belt.
[0010] A first sensor is installed on one side of the feeding conveyor belt in the direction of material inflow.
[0011] The beneficial effects of this utility model are as follows: This utility model has a feeding conveyor belt driven by a first motor and a discharging conveyor belt driven by a second motor installed behind the processing table. The feeding conveyor belt is connected to the incoming material conveyor belt of the production line, and the discharging conveyor belt is connected to the feeding conveyor belt of the production line. The feeding conveyor belt has a feeding port on the left side of the processing table, and a feeding cylinder is installed on the feeding conveyor belt corresponding to the feeding port. The discharging conveyor belt has a discharging port on the right side of the processing table for feeding products onto the discharging conveyor belt. Products from the production line are transported to the feeding conveyor belt via the incoming material conveyor belt, and the feeding cylinder pushes the products from the feeding port onto the processing table. After processing is completed, the workers manually feed the products from the discharging port onto the discharging conveyor belt, which then transports them to the next process via the feeding conveyor belt of the production line. This eliminates the need for additional workers for turnover. Furthermore, the processing workers can take the next product only after completing the processing of one product, avoiding the problem of product accumulation. Attached Figure Description

[0014] Figure 2 This is the second structural diagram of this utility model. Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0016] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.
[0017] The following describes some embodiments of the present invention with reference to the accompanying drawings.
[0018] Reference Figure 1-2A semi-automatic loading and unloading processing table includes a processing table 1. A loading conveyor belt 3 driven by a first motor 2 and a unloading conveyor belt 5 driven by a second motor 4 are installed at the rear of the processing table 1. The loading conveyor belt 3 is connected to the incoming material conveyor belt of the production line, and the unloading conveyor belt 5 is connected to the feeding conveyor belt of the production line. The loading conveyor belt 3 has a loading port 6 on the left side of the processing table 1, and a loading cylinder 7 is installed on the loading conveyor belt 3 corresponding to the loading port 6. The unloading conveyor belt 5 has a unloading port 8 on the right side of the processing table 1 for feeding products onto the unloading conveyor belt 5. Products from the production line are transported to the loading conveyor belt 3 via the incoming material conveyor belt, and the loading cylinder 7 unloads the products from the loading conveyor belt 3. The feed port 6 pushes the product onto the processing table 1. (For heavier products, the feed cylinder 7 pushes the product slowly, with the push rod of the feed cylinder 7 always in contact with the product, rather than being pushed out instantly. After impacting the product, it is given an initial velocity, which moves it onto the processing table. For lighter products, the pushing speed can be increased, but it is also necessary to ensure that the product is not damaged.) After processing, the product is manually fed from the unloading port 8 to the unloading conveyor belt 5 by the worker. The product is then transported to the next process by the production line's feeding conveyor belt. No additional workers are needed for turnover. At the same time, the processing worker takes the next product after completing the processing of one product, avoiding the problem of product accumulation.
[0019] A connecting belt 9 is provided on the feeding port 6 towards the processing table 1. The end of the connecting belt 9 abuts against the processing table 1. The connecting belt 9 mainly serves as a connecting channel between the feeding conveyor belt 3 and the processing table 1. When the feeding cylinder 7 pushes the product out of the feeding port 6, it moves along the connecting channel to the processing table 1. The top surface of the feeding conveyor belt 3 is not lower than the top surface of the connecting belt 9, and the top surface of the connecting belt 9 is not lower than the table surface of the processing table 1 to avoid the problem of the product getting stuck when moving. In addition, the connecting belt 9 can be a horizontal structure or a structure that slopes downward towards the processing table 1, so that the product can be conveyed more smoothly.
[0020] Furthermore, several rollers can be installed on the connecting belt 9 to further improve the smoothness of product conveying.
[0021] The unloading conveyor belt 5 is located below the loading conveyor belt 3. A downward sliding belt 10 is provided on the right side of the processing table 1 in the direction of the unloading conveyor belt 5. The end of the sliding belt 10 is matched with the unloading port 8. When the worker finishes processing the product, he places the product on the sliding belt 10 and slides it down to the unloading conveyor belt 5 due to gravity.
[0022] Furthermore, several rollers can also be installed on the sliding belt 10 to further improve the smoothness of product conveying.
[0023] A first sensor 11 is provided on one side of the feeding conveyor belt 3 in the material receiving direction. When the product passes the first sensor 11, it is detected by the first sensor 11. When the product is aligned with the feeding port 6, the first motor 2 is controlled to stop. At this time, the feeding cylinder 7 is started to push the product toward the processing table 1.
[0024] Because there is a positional difference between the first sensor 11 and the feeding port 6, when the product is touched by the first sensor 11, the first motor 2 stops immediately. The product is very likely to be misaligned with the feeding port 6. At this time, the feeding cylinder 7 cannot push the product to the processing table 1.
[0025] Furthermore, by setting up the program and debugging it (the program is a conventional technology), the first sensor 11 detects the product, and after a period of time (0.5 seconds to 3 seconds, which is adjusted according to the actual distance and the product's conveying speed, etc.), the first motor 2 is stopped to ensure that the product is aligned with the feed port 6.
[0026] A second sensor 12 is installed on the sliding belt 10. The second sensor 12 is used to detect whether the product leaves the sliding belt 10, thereby determining whether the worker has completed the processing of a product. When the second sensor 12 detects the product, the corresponding first sensor 11 will be activated to avoid the problem of product accumulation caused by the product to be processed being sent to the processing table 1 through the feeding port 6 when the worker has not completed the processing.
[0027] The feeding conveyor belt 3 and the incoming material conveyor belt of the production line are driven by different drive devices. Therefore, when the feeding conveyor belt 3 stops, even if the incoming material conveyor belt continues to transport products, the products will only accumulate at the end of the incoming material conveyor belt and the front end of the feeding conveyor belt 3. This situation may be caused by reasons such as the worker's processing speed not being able to keep up. Ideally, when the incoming material conveyor belt transports a product, there should just be a worker who is free to receive the product.
[0028] In this embodiment, the number of processing tables 1 can be one or more, and all processing tables 1 share a set of feeding conveyor belt 3 and unloading conveyor belt 5.
[0029] The working process when the number of processing tables 1 is one:
[0030] When the processing table is started, the product on the feeding conveyor belt 3 is detected by the first sensor 11, the feeding conveyor belt 3 stops, the product stops at the position corresponding to the feeding port 6, and the first sensor 11 stops working. The feeding cylinder 7 pushes the product to the processing table 1. After the worker finishes processing, the product is sent to the unloading conveyor belt 5 through the sliding belt 10 and the unloading port 8. At this time, the second sensor 12 detects the product, the first sensor 11 is restarted, the feeding conveyor belt 3 starts, and the next product is transported. The processed product is transported to the next process through the unloading conveyor belt 5 and the feeding conveyor belt of the production line.
[0031] The working process when there are multiple processing tables 1:
[0032] Multiple processing stations start simultaneously. When the feeding conveyor belt 3 conveys the first product to the first processing station, it is detected by the first sensor 11 of that processing station. The feeding conveyor belt 3 then stops, and the product stops at the position corresponding to the feeding port 6. At the same time, the first sensor 11 stops working, and the feeding cylinder 7 pushes the product towards the processing station 1. After the feeding cylinder 7 finishes its work, the feeding conveyor belt 3 starts again, conveying the second product to the second processing station. When the second product is detected by the first sensor 11 of that processing station, the feeding conveyor belt 3 stops, and the product stops at the position corresponding to the feeding port 6. At the same time, the first sensor 11 stops working, and the feeding cylinder 7 pushes the product towards the processing station 1. After the feeding cylinder 7 finishes its work, the feeding conveyor belt 3 starts again. This cycle continues until all processing stations have products being processed. When a processing station finishes processing, the product is fed into the unloading conveyor belt 5 through the sliding belt 10 and the unloading port 8. At this time, the second sensor 12 detects the product, and the first sensor 11 starts again, thus completing the cycle.
[0033] The entire process can be simply understood as follows: after the first sensor 11 detects a product, the feeding conveyor belt 3 stops. At the same time, after the first sensor 11 and the feeding cylinder 7 push the product to the processing table 1, the feeding conveyor belt 3 starts up. This continues until all the first sensors 11 stop. When the second sensor 12 detects a product, the corresponding first sensor 11 starts up, thus completing the cycle.
[0034] When a worker temporarily leaves their workstation, the corresponding second sensor 12 will not detect the product, and therefore the corresponding first sensor 11 will not restart.
[0035] When performing maintenance on a certain processing table, the corresponding first sensor 11 can be manually turned off.
