Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste material recycling technology, specifically to a waste screw management device. Background Technology
[0002] Screws are among the most frequently used low-value consumables on assembly lines. Although existing assembly lines are equipped with screw-making machines to supply screws, most of these lines do not manage the disposal of used screws, leading to the following problems:
[0003] 1. The product is damaged or other secondary disasters are caused by missing screws or extra screws left inside the product.
[0004] 2. Excess scrap screws may be left on the production line floor or inside other transmission components, causing waste or abnormal production line shutdowns.
[0005] Therefore, designing a waste screw management device to strictly control screws is of great significance in this field. Utility Model Content
[0006] To address the aforementioned problems, this utility model provides a waste screw management device.
[0007] The technical solution adopted in this utility model is:
[0008] A waste screw management device includes a waste collection device, a feeding device, a feeding sensor, and a PLC controller. The waste collection device includes a waste collection box for collecting waste screws, and the waste collection box is equipped with a latch. The feeding device includes a feeding hopper for receiving waste screws and a feeding cylinder for conveying screws from the feeding hopper to the waste collection box. The feeding hopper is fixed above the waste collection box by a bracket, and the outlet of the feeding hopper is connected to the feeding cylinder. The lower end of the feeding cylinder is connected to the waste collection box. The feeding sensor is located outside the feeding cylinder and is used to detect whether a screw passes through the feeding cylinder. The sensor transmits the detection signal to the PLC controller. After receiving the signal that a screw has passed through the feeding cylinder, the PLC controller accumulates the number of screws that have passed through the feeding cylinder and sends an instruction to the screw machine to control it to supply a new screw to the assembly line.
[0009] Furthermore, the waste collection box includes a drawer frame and a drawer, the drawer being slidably mounted in the drawer frame via guide rails, and the drawer being equipped with a latch.
[0010] Furthermore, the drawer front is also equipped with handles.
[0011] Furthermore, a non-metallic sensor mounting plate is provided on the top of the drawer frame, and the feeding sensor is mounted on the sensor mounting plate. The feeding sensor is a ring photoelectric sensor.
[0012] Furthermore, the bottom of the drawer frame is provided with a strip mounting plate, and mounting holes are provided on the mounting plate.
[0013] Furthermore, the support includes a vertical support and a ring support. The vertical support is fixed vertically to the top of the drawer frame, and the ring support is fixed horizontally above the vertical support. The hopper is fixedly supported inside the ring support.
[0014] The beneficial effects of this utility model are as follows: By cooperating with the waste collection device, the feeding device, the feeding sensor and the PLC controller, it is possible to ensure that the screw machine can only supply a new screw when the collection device collects a waste screw, thereby achieving complete control over the number of screws used; avoiding the omission or retention of screws in the product, and ensuring product quality and safe operation of the production line. Attached Figure Description
[0015] Figure 1 This is a structural diagram of a waste screw management device.
[0016] Figure 2 for Figure 1 Top view. Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments.
[0018] See Figure 1 and Figure 2 A waste screw management device includes a waste collection device, a feeding device, a feeding sensor 11, and a PLC controller.
[0019] The waste collection device includes a drawer frame 3, a drawer 5, and a sensor mounting plate 4. The bottom of the drawer frame 3 has two elongated mounting plates 31 with mounting holes for fixing the device onto the assembly line. The drawer 5 slides within the drawer frame via guide rails and has a latch 1 and a handle 2. The sensor mounting plate 4 is fixed to the top of the drawer frame 3. Preferably, the sensor mounting plate 4 is made of plastic to prevent interference with sensor signal detection.
[0020] The feeding device includes a feeding hopper 7 and a feeding cylinder 8. The feeding hopper 7 is fixedly mounted on the drawer frame 3 via a vertical bracket 9 and an annular bracket 10. The upper end of the feeding cylinder 8 is fixedly fitted onto the outlet of the feeding hopper, and the lower end extends vertically downward through the sensor mounting plate 4 and the upper side plate of the drawer frame to communicate with the inner cavity of the drawer 5. The vertical bracket 9 is vertically fixed on the drawer frame 3, and the annular bracket 10 is horizontally fixed on the upper end of the vertical bracket 9. The feeding hopper 7 is supported in the annular cavity of the annular bracket 10 by screws.
[0021] The feeding sensor 11 is a ring-shaped photoelectric sensor, which is fixedly mounted on the sensor mounting plate 4 with screws, and the feeding cylinder 8 passes through its annular cavity. Preferably, the feeding sensor 11 is the Jiazhun FSNA30-P model.
[0022] The PLC controller is existing technology and is connected to the feeding sensor 11 and the screw machine via wires. The PLC controller has a counter used to accumulate the number of screws dropped. The preferred PLC controller is the Siemens 1214C (6ES7214-1AG40-0XB0) model.
[0023] The working principle of this utility model is as follows:
[0024] After a scrap screw removed from the assembly line is placed into the feeding hopper 7 by a manual worker, the screw falls into the drawer 5 through the feeding cylinder 8. When it passes the feeding sensor 11, the sensor is triggered, and the sensor transmits the signal to the PLC controller. The PLC controller counts and triggers the screw machine to provide a new screw to the assembly line.
[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications are also within the protection scope of the present utility model.
