Description

Technical Field

[0001] The utility model relates to canned production equipment, in particular to a device for installing a top cover of a canned product and removing unqualified products. Background Art

[0002] Canned products with lids on the top are one of the most commonly used packaging products. The top covers of canned products include press-fitted caps and screw-fitted caps. Regardless of the type of lid, whether it is properly closed involves the sealing and safety of the product. However, during the production process, due to production line errors, insufficient materials, inaccurate precision, etc., the top cover is often not installed properly or even missed. In order to remove these unqualified products, manual inspection and screening of canned products is currently required, which not only requires high labor costs, but also reduces production efficiency, and still cannot guarantee the accuracy of the inspection. If unqualified products flow out, it will seriously affect the quality and evaluation of the product. Utility Model Content

[0003] The utility model aims to provide a top cover detection and rejection device which can automatically detect and reject unqualified canned products, so as to improve detection accuracy, production efficiency and production quality.

[0004] The top cover detection and rejection device described in the utility model comprises a conveying line for conveying products, a rejection frame for temporarily storing unqualified products is installed on one side of the conveying line, a conveying baffle for limiting and guiding products is installed on the conveying line, the conveying baffle forms a conveying channel for conveying products one by one, a rejection port is opened on the side of the conveying baffle facing the rejection frame, a rejector for pushing the product out of the rejection port is installed on the other side of the conveying channel opposite to the rejection port, a height meter for detecting the height of the product is provided at the upstream of the rejection port, and a control system receives a signal from the height meter and controls the operation of the rejector.

[0005] Furthermore, the reject frame is tilted from one side close to the conveyor line toward the other side, and a full load detector is also installed on the side of the reject frame close to the conveyor line.

[0006] Furthermore, the conveying baffle includes two groups of baffles arranged along the conveying direction, one end of the two groups of baffles are opposite to each other and form a rejection port, and the width of the conveying channel formed by the two groups of baffles gradually increases from one end of the rejection port to the other end.

[0007] Further, the rejector is a robot, a cylinder or a telescopic device that reciprocates toward the reject opening.

[0008] Furthermore, the height meter includes a low-position detector, and a setting height of the low-position detector is higher than the height of the product without the top cover installed and lower than the height of the product with the top cover installed.

[0009] Furthermore, the height meter also includes a high-position detector, and the setting height of the high-position detector is higher than the preset height range for correctly installing the top cover of the product.

[0010] Furthermore, there is an arrival detector for detecting that the product has reached the detection position.

[0011] Furthermore, there is a height adjustment mechanism that can be raised and lowered, and the height measuring device is installed on the height adjustment mechanism.

[0012] Furthermore, the height adjustment mechanism includes a fixedly installed fixing seat, a screw rod vertically and rotatably installed on the fixing seat, a rotating wheel driving the screw rod to rotate is installed on the top of the screw rod, and a lifting seat is installed with a screw nut, a lifting guide rod is fixedly connected to the lifting seat, a guide hole for the lifting guide rail to pass through is opened on the fixing seat, the bottom of the lifting guide rod passes through the guide hole and is connected to the lifting frame, and the height meter is installed on the lifting frame.

[0013] Furthermore, the low-position detector and the high-position detector are detachably mounted on the lifting frame through mounting plates respectively.

[0014] In the top cover detection and rejection device of the utility model, canned products move with the conveyor line and are conveyed one by one when passing through the conveying baffle; when the products are conveyed to the height gauge, the height gauge will detect the height of the products. Since the heights of the canned products when they are equipped with top covers are different, the height gauge can judge whether the products are equipped with top covers according to the detection results, and then send the detection results to the control system; then, the products whose heights have been detected continue to move along the conveying channel to between the rejector and the rejection port. If the detection result is qualified, that is, the height is consistent with the preset height or is within the preset range, the rejector will not move, and the products will be conveyed to the subsequent process with the conveyor line; if the detection result is unqualified, that is, the top cover is not installed, the control system will control the rejector to move toward the unqualified products, and apply a thrust directed to the rejection port to the unqualified products, so that the unqualified products are pushed out from the rejection port and fall into the rejection frame for temporary storage, waiting for further processing before being put back into the conveyor line. This top cover detection and rejection device automatically detects products according to the different heights caused by the top cover installation conditions, and can quickly and accurately reject unqualified products, effectively improving detection accuracy and production efficiency, greatly reducing the unqualified rate, thereby improving product quality and corporate image.

[0018] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] If there are descriptions involving "first" or "second" in the embodiments of the utility model, the descriptions of "first" or "second" are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0021] The utility model provides a top cover detection and rejection device.

[0022] The top cover detection and rejection device of the present embodiment includes a conveyor line 1 for conveying products, a rejection frame 2 for temporarily storing unqualified products is installed on one side of the conveyor line, a conveying baffle 3 for limiting and guiding the products is installed on the conveyor line, the conveying baffle forms a conveying channel for conveying the products one by one, a rejection port 31 is opened on the side of the conveying baffle facing the rejection frame, a rejector 4 for pushing the product out of the rejection port is installed on the other side of the conveying channel opposite to the rejection port, a height meter 5 for detecting the height of the product is provided at the upstream of the rejection port, and the control system receives the signal of the height meter and controls the operation of the rejector.

[0023] like Figure 1-3As shown, the canned products 10 move with the conveyor line and are conveyed one by one when passing through the conveying baffle; when the product is conveyed to the height meter, the height meter will detect the height of the product. Since the height of the canned product is different when it is equipped with a top cover or not, the height meter can determine whether the product is equipped with a top cover according to the detection result, and then send the detection result to the control system; then, the product whose height has been detected continues to move along the conveying channel to between the rejector and the reject port. If the detection result is qualified, that is, the height is consistent with the preset height or is within the preset range, the rejector will not move, and the product will be sent to the subsequent process with the conveyor line; if the detection result is unqualified, that is, the top cover is not installed, the control system will control the rejector to move towards the unqualified product, and apply a thrust to the unqualified product pointing to the reject port, so that the unqualified product is pushed out from the reject port and falls into the reject frame for temporary storage, waiting for further processing before being put back into the conveyor line.

[0024] The top cover detection and rejection device described above has a rejection frame 2 that is tilted from one side close to the conveyor line 1 to the other side so that unqualified products can fall into the rejection frame more easily. At the same time, a full load detector 6 is installed on the side of the rejection frame close to the conveyor line. When unqualified products accumulate at the full load detector, the control system sends a warning signal or controls the conveyor line to stop conveying to remind the staff to deal with the unqualified products in the rejection frame in a timely manner to avoid excessive products accumulating at the rejection port and causing squeezing, and to better prevent unqualified products from flowing into subsequent processes. The full load detector 6 described above can be a photoelectric sensor, which has a simple structure, low cost, and stable and accurate operation.

[0025] The top cover detection and rejection device described, the conveying baffle 3 includes two groups of baffles arranged along the conveying direction, one end of the two groups of baffles are opposite to each other and form a rejection port 31, and the width of the conveying channel formed by the two groups of baffles gradually increases from one end of the rejection port to the other end, forming a trumpet-shaped structure, which can not only sort the upstream products and form one-by-one conveying at the height meter and the rejection port, but also enable a certain amount of qualified products to exist downstream to facilitate the processing of subsequent processes.

[0026] The top cover detection and rejection device, the rejector 4 can be a manipulator, or a cylinder, or other telescopic device that reciprocates toward the rejection port, which will not be described in detail here.

[0027] In the top cover detection and rejection device, the height meter 5 includes a low-position detector 51. The setting height of the low-position detector is higher than the height of the product without the top cover installed and lower than the height of the product with the top cover installed. When the low-position detector does not receive a detection signal, it can be concluded that the product has not installed the top cover and is a defective product; at the same time, the height meter 5 can also include a high-position detector 52. The setting height of the high-position detector is higher than the preset height range of the product when the top cover is correctly installed. This is because in addition to the correct installation of the top cover, there may be situations such as inadequate installation and misalignment when the top cover is installed. At this time, the top cover will be higher than its height when it is correctly installed. For this reason, a high-position detector is added. When both the low-position detector and the high-position detector have no detection signals, the product has not installed the top cover; when the low-position detector has a detection signal and the high-position detector has no detection signal, the product has correctly installed the top cover; when both the low-position detector and the high-position detector have detection signals, the product has not installed the top cover and the product has incorrect top cover installation; thereby, defective products in different states can be accurately detected, further improving the detection accuracy and product quality. In addition, there is an in-place detector 53 for detecting the arrival of the product at the detection position. When it is detected that the product moves along the conveyor line to the height measurement area, the low-level detector and the high-level detector perform detection again and send the detection signal to the control system to avoid detection errors. The low-level detector 51, the high-level detector 52 and the in-place detector 53 can all be photoelectric sensors.

[0028] The height gauge of the top cover detection and rejection device can be fixedly installed or provided with a height adjustment mechanism 7 that can be lifted and lowered. The height gauge 5 is installed on the height adjustment mechanism so as to adjust the height of the gauge to meet the conveying and detection needs of different products. The height adjustment mechanism 7 includes a fixedly installed fixed seat 71, a screw 72 vertically and rotatably installed on the fixed seat, a rotating wheel 73 driving the screw to rotate is installed on the top of the screw, and a lifting seat 74 with a screw nut is installed. A lifting guide rod 75 is fixedly connected to the lifting seat, a guide hole for the lifting guide rail to pass through is opened on the fixed seat, and the bottom of the lifting guide rod passes through the guide hole and is connected to a lifting frame 76, and the height gauge 5 is installed on the lifting frame; the screw is driven to rotate by rotating the rotating wheel, and then the screw drives the lifting seat, the lifting guide rod, the lifting frame and the height gauge thereon to achieve height adjustment to meet the detection needs of the top covers of canned products of different specifications, and the adjustment accuracy of the screw is extremely high, which can ensure the detection accuracy. The low position detector 51 and the high position detector 52 can be connected to different height adjustment mechanisms respectively, or they can be partially or completely installed on the same height adjustment mechanism. Figure 3 As shown, the low-position detector 51 and the high-position detector 52 are detachably mounted on the lifting frame 76 through the mounting plate 8 to meet the adjustment requirements of the top cover with the same thickness.
