Technical Field

[0001] The utility model relates to a detection system for a drinking water filling production line and a multi-station rotary leak detection device. Background Art

[0002] In the production of bottled water, the buckets need to be leak-checked, cleaned, and disinfected. It is also necessary to check whether there are foreign objects inside the buckets. When leak-checking the buckets, a leak detection device is required. Most existing leak detection devices use linear leak detection devices, which occupy a large area. In addition, most existing production lines use a single leak detection device, which may miss detection. Therefore, how to reduce the space occupied by the production line and improve the accuracy of leak detection is an urgent problem to be solved. Summary of the invention

[0003] The utility model aims to provide a multi-station rotary leak detection device for a drinking water filling production line, which can reduce the space occupied by the production line.

[0005] The rotating mechanism includes a base plate, a core column installed on the base plate, an upper disc rotatably connected to the upper end of the core column and a lower disc rotatably connected to the lower end of the core column, a driving component installed on the base plate for driving the lower disc to rotate, a plurality of guide columns connected between the upper disc and the lower disc, a plurality of sliding support frames slidable up and down and installed between two adjacent guide columns and arranged in a ring shape around the core column, a rotating leak detection mechanism is fixed on the upper disc and arranged corresponding to each sliding support frame, the guide columns are distributed in a ring shape on the upper disc with the axis of the core column as the axis center line, and the rotating leak detection mechanism includes a filling detection telescopic member fixed on the upper disc and corresponding to the sliding support frame, a filling detection telescopic member installed on the filling detection telescopic member Head, a workstation is formed between two adjacent guide pillars, and the three workstations are respectively the feeding station, the discharging station and the sending-out station. After the bucket is transported to the feeding station by the conveyor belt, the rotary leak detection mechanism first descends a distance for leakage detection. If there is a leak, the rotary leak detection mechanism continues to descend to press the bucket and the sliding support frame where the bucket is located to the discharge height, and then the leaking bucket is pushed out manually or by other pushing parts. If there is no leak, the bucket rotates through the discharge station, and the rotary leak detection mechanism is used for filling until the sending-out station, when the filling is completed. At this time, the conveyor belt sends the filled bucket to the next process. The water supply and air supply channels on the filling detection head are realized through a rotary joint structure, and the rotary joint can be a rotary joint produced by Shandong Hongsheng Machinery Manufacturing Co., Ltd. and other companies.

The dial-out shaft drives the dial-in shaft to rotate through the pulley group, and the dial-in disc rotates accordingly. The second gear drives the lower gear to rotate, which in turn drives the upper gear to rotate.

[0022] The present utility model will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0023] As Figures 1-3 shown, the leak detection device includes: a leak detection machine frame A0, a conveyor belt 6, a detection mechanism 5, a positioning mechanism 4, a clamping mechanism 3, and a lifting mechanism 2.

[0024] The leak detection machine frame A0 has an upper mounting plate 01 and a lower mounting plate 02 located below the upper mounting plate 01; the conveyor belt 6 is installed on the lower mounting plate 02; the detection mechanism 5 includes a detection telescopic member 51 installed on the upper mounting plate 01 and a leak detection valve 52 installed on the detection telescopic member 51; the lifting mechanism 2 includes a lifting telescopic member 21 installed on the upper mounting plate, a lifting frame 22 connected to the lifting telescopic member 21, and the lifting telescopic member 21 drives the lifting frame 22 to move up and down;

[0025] The clamping mechanism 3 is installed on the lifting frame 22, and includes a clamping guide rod 31 fixed on the lifting frame 22 and arranged in the horizontal direction, a first clamping longitudinal rod 32 and a second clamping longitudinal rod 33 slidably connected to the clamping guide rod 31, clamping heads 34 respectively arranged on the first clamping longitudinal rod 32 and the second clamping longitudinal rod 33 and arranged oppositely, and a clamping telescopic member 35 fixed on the lifting frame 22 for driving the first clamping longitudinal rod 32 and the second clamping longitudinal rod 33 to move towards or away from each other. The clamping heads 34 on the first clamping longitudinal rod 32 and the second clamping longitudinal rod 33 correspond one by one, and the paired clamping heads 34 can clamp the bucket mouth of the water bucket 1 after closing. The paired clamping heads are located on both sides below the detection mechanism 5, and multiple pairs of clamping heads are arranged along the conveying direction of the conveyor belt 6.

[0026] The lifting frame 22 includes several lifting guide rods 221 movably arranged in the up and down direction and passing through the upper mounting plate 01, an upper connecting plate 222 connected to the upper ends of the lifting guide rods 221 to make the lifting guide rods 221 move synchronously, and a lower connecting plate 223 connected to the lower ends of the lifting guide rods 221. The lifting telescopic member 21 is fixedly connected to the upper connecting plate 222, and the clamping mechanism 3 is installed on the lower connecting plate 223.

[0027] On the leak detection rack A0 and above the conveyor belt 6, there is a positioning mechanism 4 for assisting in the positioning of each water bucket 1. The positioning mechanism 4 includes positioning telescopic members 41 fixed on the leak detection rack A0 and on both sides of the conveyor belt 6, and positioning heads 42 mounted on the positioning telescopic members and having semi-circular positioning surfaces. The two relatively arranged positioning heads and another water bucket 1 adjacent to the water bucket 1 position the water bucket 1 from three directions, so that the water bucket 1 is moved directly below the detection mechanism 5. Subsequently, the lifting telescopic member and the detection telescopic member act simultaneously, causing the bucket mouth and the leak detection valve to move towards each other, shortening the stroke where only the bucket mouth moves or only the leak detection valve moves. This not only shortens the overall movement time but also improves the action consistency of the leak detection valve. The lifting telescopic member 21 and the detection telescopic member 51 are fixed on the upper mounting plate 01, which can reduce the load during lifting and reduce energy consumption.

The shifting mechanism D3 shifts the row of water buckets 1 on the first conveyor mechanism D1 onto the support plate, and the positioning component D44 clamps each water bucket to move the water bucket below the visual detection probe D43 to complete the detection. After the shifting mechanism D3 resets, it shifts another group of water buckets 1, and the previous group of water buckets advances to the second conveyor mechanism D2 under the push of this group of water buckets 1 to complete an action cycle.

[0029] The shifting mechanism D3 includes a swing arm D31 rotatably connected at one end to the foreign object detection rack B0, a shift rod D32 connected to the other end of the swing arm D31 and arranged in the front-rear direction, and a shifting telescopic member D33 rotatably connected at one end to the foreign object detection rack B0 and rotatably connected to the middle of the swing arm at the other end.

[0033] The rotating mechanism 7 includes a base plate 71, a core column 72 mounted on the base plate 71, an upper disc 70 rotatably connected to the upper end of the core column 72, and a lower disc 73 rotatably connected to the lower end of the core column 72, a driving assembly 74 mounted on the base plate 71 for driving the lower disc 73 to rotate, a plurality of guide columns 75 connected between the upper disc 70 and the lower disc 73, and a plurality of sliding support frames 76 slidably mounted between two adjacent guide columns 75 and arranged in a ring shape around the core column 72; the rotating leak detection mechanism is fixed on the upper disc 70 and is arranged corresponding to each sliding support frame 76, and the guide columns 75 are distributed in a ring shape on the upper disc 70 with the axis of the core column 72 as the axis center line. The rotating leak detection mechanism includes a filling detection telescopic member 81 fixed on the upper disc 70 and corresponding to the sliding support frame 76, and a filling detection head 82 mounted on the filling detection telescopic member 81, such as Figure 8 As shown, the filling detection head 82 includes a leak detection section 83, an air valve 84 and an air pressure detector 85 installed on the leak detection section 83, a filling section 86 penetrated through the leak detection section 83, a water valve 87 installed on the filling section 86, and a filling reset spring 89 connected between the leak detection section 83 and the filling section 86 so that the two always have opposite movement trends. When the air valve 84 moves downward and is pressed and fitted with the water bucket 1, the air valve 84 opens to inflate the water bucket 1 and maintain the pressure for a period of time. If the air pressure detector 85 does not detect a drop in air pressure, there is no leakage. If a drop in air pressure is detected, there is a leakage. A workstation is formed between two adjacent guide pillars 75, and the three workstations are respectively a feeding workstation E, a discharge workstation F and a delivery workstation G.

[0034] The toggle mechanism includes an inlet plate 91 suspended above the conveyor belt, an inlet disk 92 arranged upstream of the feeding station E and located on one side of the conveyor belt, and an outlet disk 93 arranged downstream of the delivery station G and located on one side of the conveyor belt. The inlet plate 91 is provided with an arc-shaped inlet surface H and an outlet surface I, the inlet surface H is located upstream of the feeding station E, and the outlet surface I is located downstream of the delivery station G. The inlet disk 92 and the outlet disk 93 are provided with an arc-shaped toggle surface J, and the inlet disk 92 and the outlet disk 93 are transmission-connected to the drive assembly 74.

[0035] The driving assembly 74 includes a rotation detection motor 77, a first gear 78 coaxially and fixedly connected to the output shaft of the rotation detection motor 77, a dial-in shaft 79 coaxially fixed to the dial-in disk 92, a dial-out shaft 710 coaxially and fixedly connected to the dial-out disk 93, a second gear 711 connected to the dial-out shaft 710 and meshing with the first gear, a pulley group 712 connected between the dial-in shaft 79 and the dial-out shaft 710, a lining disk 713 sleeved on the lower end of the core shaft and coaxially and fixedly connected to the base disk 71, a gear ring 714 sleeved on the lining disk 713 and rotatably connected to the lining disk 713 through a bearing, a conversion rotating shaft 715 fixedly penetrating through the base disk 71, an upper gear 716 rotatably connected to the upper end of the conversion rotating shaft 715, and a lower gear 717 rotatably connected to the lower end of the conversion rotating shaft 715. The lower gear 717 meshes with the second gear 711, and the lower gear 717 meshes with the gear ring 714. When the rotation detection motor 77 rotates, it drives the first gear 78 to rotate. The first gear 78 drives the second gear 711 on the dial-out shaft 710 to rotate, and the dial-out disk 93 rotates accordingly. The dial-out shaft 710 drives the dial-in shaft 79 to rotate through the pulley group 712, and the dial-in disk 92 rotates accordingly. The second gear 711 drives the lower gear 717 to rotate, which in turn drives the upper gear 716 to rotate. The upper gear 716 drives the gear ring 714 to rotate, which in turn drives the core column 72, the upper disk 70, and the lower disk 73 to rotate together. On the lower disk 73 and at each working station, there are provided support frame sliding columns 718, and a coil spring 719 connecting the upper end of the support frame sliding column 718 and the sliding support frame 76. The inner side of the sliding support frame 76 is in sliding fit with the peripheral surface of the guide post 75 through an arc-shaped sliding plate. The outer side of the sliding support frame 76 is sleeved on the support frame sliding column 718. When the water bucket 1 is detected to have air leakage, the filling detection telescopic member 81 overcomes the pulling force of the coil spring and presses down the sliding support frame 76 to make the water bucket 1 enter the discharge station F, and the discharge station F is lower than the feeding station E and the discharging station G.

[0036] The detection telescopic member 51, the positioning telescopic member 41, the lifting telescopic member 21, the clamping telescopic member 35, the alignment telescopic member D442, and the shifting telescopic member D33, and the filling detection telescopic member 81 are cylinders or hydraulic cylinders.

[0037] The working principle of the detection system for the drinking water filling production line is as follows: After the water bucket 1 is conveyed by the conveyor belt to the feeding station E, the filling detection head 82 of the rotary leak detection mechanism first descends a certain distance for leak detection. If there is air leakage, the rotary leak detection mechanism continues to descend to press the water bucket 1 and the sliding support frame 76 where the water bucket 1 is located to the discharge height, and then the leaking water bucket 1 is pushed out by manual or other pushing parts. If there is no air leakage, after the water bucket 1 rotates past the discharge station F, the rotary leak detection mechanism continues to descend so that the filling section 86 presses against the leak detection section 83 and the water outlet formed on the circumferential surface of the filling section 86 is offset from the inner wall of the leak detection section 83, and then the water valve 87 is opened for filling. When it reaches the sending station G, the filling is completed. At this time, the conveyor belt sends the filled water bucket 1 to the next process. The water supply channel and the air supply channel on the filling detection head 82 are realized through the rotary joint 88 structure. The pipelines K1 on the air source and the water source are respectively connected to the pipeline K2 on the rotary joint 88 and the filling detection head 82. The pipelines K1 on the air source and the water source are coaxially and fixedly connected to the core column 71. The rotary joint 88 is installed on the upper disc 70. The rotary joint 88 can be a rotary joint produced by companies such as Shandong Hongsheng Machinery Manufacturing Co., Ltd.

[0038] The detection system for the drinking water filling production line includes a leak detection device, a foreign object detection device, and a multi-station rotary leak detection device. The leak detection device conveys the water bucket 1 to the first conveyor mechanism D1 of the foreign object detection device through the conveyor belt 6, and the second conveyor mechanism D2 of the foreign object detection device conveys the water bucket 1 to the conveyor belt C1 of the multi-station rotary leak detection device.
