Technical field

The invention relates to the technical field of labeling equipment, in particular to a waste rejection mechanism and a waste rejection device.

Background technique

At present, in the automated processing of pharmaceutical products, due to manual operation errors, machine work errors, poor coordination of various parts of the machine and other factors, non-conforming products are produced, which greatly affects the product quality and production efficiency of the enterprise. If the unqualified drugs are inadvertently put into the market, it will have a bad impact on the normal production of the enterprise, and even bring disaster to the enterprise. In order to prohibit the non-conforming products from entering the market, it is usually necessary to remove the non-conforming products from the production line. The current prevailing practice is to rely on the detection device to test the products on the production line one by one. When the non-conforming product is found, the corresponding rejecting robot grabs the non-conforming product from the production line and then places it into the waste tank. Achieve the elimination of non-conforming products. However, the culling method requires high cooperation between the robot and the pipeline and the detecting device in the moving state, and requires high movement and operation precision of the robot, which increases the procurement and use cost of the enterprise, and the structure of the culling system is complicated.

It should be noted that when an element is referred to as being "fixed on", "in" or "in" another element, it may be directly on the other element or the element may be present. When an element is considered to be "connected" to another element, it can be directly connected to the other element or the central element can be present at the same time. The specific manner in which one element is fixedly connected to the other element can be achieved by the prior art. Further, it is preferable to use a fixing method of a screw connection.

All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and/or" used herein includes any and all combinations of one or more of the associated listed items.

The terms "first" and "second" in the present invention do not represent a specific number and order, but are merely used for distinguishing names.

As shown in FIG. 1 and FIG. 2, a waste rejection mechanism according to an embodiment of the present invention includes: a support base 100; a reject dial 200, and the reject dial 200 is rotatably disposed on the support base 100, and The edge of the knockout turntable 200 is recessed with at least one reject groove 210 for accommodating the product; a waste collection tank 300, the waste collection tank 300 is disposed on the support base 100, and the waste collection The slot 300 is provided with a feed port 310, the notch of the reject groove 210 is opposite to the feed port 310, and the block assembly 400 includes a drive disposed on the support base 100. An assembly 410, and a baffle plate 420 drivingly coupled to the drive assembly 410, the baffle plate 420 and the feed port 310 are openable and closable; a blow assembly 500, the blow assembly 500 includes a nozzle 510 The nozzle 510 is opposite to the feed port 310 and is used to blow waste material in the reject groove 210 into the waste collection tank 300; and a control device for acquiring a waste detection signal of the detecting device, The control device and the driving assembly 410, the blowing assembly 50 0 is electrically connected.

When the above-mentioned waste rejection mechanism is in operation, the control device acquires the detection device to detect the waste signal, when the The scrap enters the reject recess 210 of the reject dial 200 and then rotates together with the reject dial 200 to oppose the feed port 310; at this time, the control device first drives the drive assembly 410 of the block assembly 400 to act, thereby driving the baffle plate. The 420 is separated from the feed port 310, and then the blow-off assembly 500 is supplied with air, so that the nozzle 510 ejects the high-pressure gas, and the waste in the groove is fed into the waste collection tank 300. Qualified products are removed from the production line. Through the synergistic cooperation of the above components, not only the reliable rejection of the non-conforming products can be achieved, the working performance is reliable, and the working principle and the connection structure are simple, which is beneficial to reducing the procurement and use cost of the enterprise and improving the economy.

It should be noted that the above control device may be a PLC. In addition to acquiring the detection signal fed back by the detecting device at the detecting front end detecting station, the PLC also receives the position signal of the non-conforming product fed back by the angle encoder, so that the control device is located on the flowing water production line. When all the products are removed from the turntable 200, only when the defective product is rotated to the rejecting station (and when the recess 210 is opposite to the feeding port 310 of the waste collecting tank 300), the PLC drives the shutter to move and open. The material port 310 further drives the blowing assembly 500 to discharge high-pressure gas from the nozzle 510, and blows the non-conforming product into the waste collecting tank 300 to complete the rejecting operation of the non-conforming product, so that the device has high rejection precision and no leakage occurs. Eliminate and eliminate the problem. In order to facilitate understanding of the technical solution, the above product can be described by taking a syringe as an example. The syringe is assembled by a syringe and a needle tube; when the detecting device detects that the syringe is a non-conforming product, the syringe located on the assembly line at this time is only a needle.

Therefore, the precise control of the working airflow is realized by the electrical connection between the control device and the first electromagnetic valve and the second electromagnetic valve, and the reliable cooperation of the retaining plate 420 and the nozzle 510 can be ensured, thereby ensuring that the non-conforming product is removed and avoided. The problem of wrong rejection or missing rejection improves the performance of the device. Specifically, the gas source member may be a high pressure gas tank, which is in a normally open state, and supplies air to the cylinder 411 and the nozzle 510 through a pipeline; the first electromagnetic valve and the second electromagnetic valve are used to respectively control the cylinder 411 and the nozzle 510. When to work and the sequence of actions to ensure that the defective syringe is reliably removed from the production line.

In addition, the support base 100 is further provided with a sliding guide groove (not shown) near the feed port 310, and the baffle plate 420 is slidably disposed in the sliding guide groove. In this way, the baffle plate 420 can be slid in a preset path to open or close with the feed port 310, thereby ensuring that the defective product can be reliably removed. Specifically, the sliding guide groove is a U-shaped clamping plate disposed on one side of the feeding port 310. The shielding plate 420 is embedded in the cavity formed by the U-shaped clamping plate and arranged perpendicular to the end surface of the feeding opening 310. The support base 100 is located at the U-shaped plate to provide a through cavity, so that the piston rod of the cylinder 411 is connected with the baffle plate 420. drive.

Referring to FIG. 2, the support base 100 is further provided with an oblique bracket 120. The waste collection slot 300 is disposed on the diagonal bracket 120, and the waste collection slot 300 is away from the inlet. One end of the spout 310 is provided with a stopper 320. In this way, the rejected defective products can be sequentially slid down to the waste collection tank 300 by their own gravity to realize an orderly arrangement without adding an auxiliary driving device (for example, a conveyor belt) for moving the defective products, which can simplify the overall structure of the device and reduce manufacturing and The cost of use, while the stop 320 at the end of the waste collection tank 300, also ensures that the rejects do not fall.
