Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of food packaging, specifically relates to a cover detection and blowing and removing mechanism for cover pressing machine production line. BACKGROUND

[0002] The cover pressing machine production line refers to an automatic production line for sealing covers of various canned products (such as milk powder, egg white powder, etc.).

[0003] After the container filled with products enters the cover pressing machine production line, the cover is first placed on the container mouth by the cover placing mechanism, and then the cover is pressed and sealed on the container mouth by the cover pressing mechanism. Since the cover placing mechanism allocates covers for each container, there may be a missing situation, causing the coverless container to flow into the cover pressing mechanism in the later stage, and further causing equipment failure downtime or generating coverless products flowing into the market to cause quality risks.

[0004] At present, in order to solve the above problems, a removing mechanism is usually arranged on the transportation line between the cover placing mechanism and the cover pressing mechanism for identifying and removing the coverless container on the transportation line. The existing removing mechanism usually adopts a pneumatic cylinder as an action execution structure for removing the coverless container, such as the Chinese utility model patent with the authorization announcement number CN214289484U, which discloses a removing device for a cover pressing machine and a cover pressing machine. It controls the opening and closing of the removing cylinder by an electromagnetic valve to horizontally push the identified coverless container from the transportation line to the collecting mechanism. However, such removing mechanism has the following problems in actual application:

[0005] Each extension and retraction of the pneumatic cylinder needs a certain time, and the longer the stroke, the longer the extension and retraction time. When the containers on the transportation line are closely spaced (such as a 170g small can pressing machine production line), and there are two or more adjacent coverless containers that need to be removed on the transportation line, the single extension and retraction time of the pneumatic cylinder is long, and the action frequency of the pneumatic cylinder is lower than the transportation frequency of the containers on the transportation line, and thus all the adjacent coverless containers cannot be continuously removed, causing the coverless containers to flow into the cover pressing mechanism in the later stage. UTILITY MODEL CONTENTS

[0006] In order to solve the above problems in the prior art, the utility model aims to provide a cover detection and blowing and removing mechanism for a cover pressing machine production line to accurately remove each can of coverless container and avoid the coverless container flowing into the later stage to cause equipment failure downtime or quality risks.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cover detection and blowing and removing mechanism for a cover pressing machine production line, comprising a controller, a cover detection assembly arranged above a transportation line of the cover pressing machine production line, and a blowing and removing assembly arranged on both sides of the transportation line.

[0010] As a limitation of the utility model, the cover placing detection assembly comprises a distance measuring sensor fixed on the conveying line through a support; the distance measuring sensor is electrically connected with the controller, and a transmitting end vertically faces downward.

[0011] As a further limitation of the utility model, a trigger photoelectric sensor is further arranged on one side of the conveying line; the trigger photoelectric sensor is electrically connected with the controller, and a transmitting end faces the product on the conveying line.

[0013] As a further limitation of the utility model, a transparent cover is arranged above the receiving platform, and an opening is arranged on one end of the transparent cover close to the conveying line.

[0014] As other limitations of the utility model, a pressure limiting valve electrically connected with the controller is arranged on the blowing pipeline.

[0015] Compared with the prior art, the utility model has the beneficial effects that:

[0016] The utility model adopts a new action execution structure for removing the coverless container, effectively solves the problem that due to the time delay characteristics of the cylinder action, the adjacent coverless containers on the small interval conveying line cannot be continuously removed, and the coverless containers flow into the rear section to cause equipment failure shutdown or quality risk.

[0022] The preferred embodiments of the utility model are described below in conjunction with the drawings. It should be understood that the preferred embodiments described here are only for illustrating and understanding the utility model, and are not intended to limit the utility model.

[0023] Embodiment A cover detection and purging rejection mechanism for capping machine production line

[0024] The embodiment is applied between the cover placing mechanism and the capping mechanism of the capping machine production line, is used for identifying the container without cover 9 that the cover placing mechanism is not distributed cover, and is rejected from the capping machine production line, avoids flowing into the later section capping mechanism and causes equipment failure stop or generates the container without cover 9 and flows into the market, causes quality risk.

[0025] Specifically, the embodiment includes a controller, a cover detection assembly and a purging rejection assembly. The controller is a PLC controller in the prior art, and is independently set or shared with the PLC controller of the capping machine production line according to the actual situation.

[0026] The cover detection assembly is arranged above the transport line 8 of the capping machine production line, and is used for identifying whether the container passing through the cover placing mechanism is distributed with the cover. It should be noted that the transport line 8 described in the embodiment is the chain plate conveyor belt connecting between the cover placing mechanism and the capping mechanism in the capping machine production line. Figure 1 As shown, the cover detection assembly is a range sensor 1 fixed above the transport line 8 through the support 2, the range sensor 1 is electrically connected with the controller, and the emission end is vertically downward. According to the characteristics that the top end of the container with cover is about 5cm higher than the top end of the container without cover 9, whether the container is the container without cover 9 is judged through the height measurement of the container by the range sensor 1.

[0027] In order to realize the precise control of the working state of the distance sensor 1, the embodiment further sets a trigger photoelectric cell 3 on one side of the conveying line 8, which is electrically connected with the controller and located on the front end of the distance sensor 1 on the conveying line 8, and the emitting end horizontally faces the container on the conveying line 8. When the container passes the position of the trigger photoelectric cell 3, the trigger photoelectric cell 3 transmits a signal to the controller, and the controller controls the distance sensor 1 to work, measures the height of the container, and transmits the measurement result to the controller to determine whether the container is the capless container 9. When no container passes the position of the trigger photoelectric cell 3, the distance sensor 1 remains in the non-working state.

[0028] The blowing and removing assembly is arranged on both sides of the conveying line 8 and corresponds to the cap placing detection assembly, which is used to remove the capless container 9 identified by the cap placing detection assembly. As shown in Figure 1 The blowing and removing assembly includes a receiving platform 4 connected with one side of the conveying line 8 and a blowing pipeline 5 arranged on the other side of the conveying line 8 and opposite to the receiving platform 4. The receiving platform 4 is provided with a detection photoelectric cell 7 at the end connected with the conveying line 8 (i.e. the entrance), which is electrically connected with the controller and the emitting end faces from one side of the receiving platform 4 to the other side. The detection photoelectric cell 7 is used to determine whether the receiving platform 4 is full of capless containers 9, i.e. when the capless containers 9 are full to the entrance of the receiving platform 4, the detection photoelectric cell 7 transmits a signal to the controller, and the controller controls the cap pressing line to stop and reminds the staff to handle.

[0029] The embodiment further covers a transparent cover (not shown in the figure) above the receiving platform 4, which is provided with an opening at the entrance of the receiving platform 4 for the capless containers 9 to enter the receiving platform 4. The transparent cover can prevent dust and prevent the container opening of the capless container 9 from being dirty.

[0030] The blowing pipeline 5 is a gas pipe connected with the external gas source, and the gas outlet faces the conveying line 8, which can blow the capless container 9 from the conveying line 8 to the receiving platform 4 on the other side. The electromagnetic valve 6 electrically connected with the controller is arranged on the blowing pipeline 5 to realize the on-off control of the gas by the controller. A pressure limiting valve electrically connected with the controller is also arranged on the blowing pipeline 5 to adjust the air outlet amount of the compressed air by the pressure limiting valve to control the blowing pressure and prevent the pressure from being too large to cause the container to be reversed.

[0031] The working process of the embodiment is as follows: as shown in Figure 2 When the container is conveyed from the cap placing mechanism to the cap pressing mechanism on the conveying line 8, the container first passes the trigger photoelectric cell 3, the trigger photoelectric cell 3 triggers the distance sensor 1 to work by the controller, the height of the container is measured by the distance sensor 1, and the result is transmitted to the controller to determine whether it is a capless container 9. If it is a capless container 9, the controller controls the blowing pipeline 5 to be connected with the external gas source by the electromagnetic valve 6, and the capless container 9 is blown to the receiving platform 4 by the compressed air.

[0032] It should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the above embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included within the scope of the present application.
