Description

Technical Field

[0001] The invention relates to the field of automatic cleaning equipment, in particular to a container cleaning machine. Background Art

[0002] The automated cleaning of barrel containers has always been a difficult problem in the field of automated cleaning equipment. The main reasons are: first, barrel containers come in many types and sizes. Although it is not difficult to develop a single type of barrel cleaning equipment, the equipment is less applicable and does not meet actual needs; second, the barrel body of a barrel container has a certain depth, and barrel containers often have dead corners, grooves, and pouring mouths that are difficult to clean, making it difficult to clean thoroughly by conventional means; third, many barrel containers are still made of plastic and are relatively light in weight. During automated cleaning, they are prone to overturning and tipping due to high-pressure water, brush rotation, or wind, resulting in transport failures. Because barrel containers have various functions such as transport and storage, they are used in large quantities in daily life, and manual cleaning is very time-consuming and laborious. Summary of the invention

[0003] Therefore, in view of the above problems, the present invention proposes a novel container cleaning machine.

[0004] The present invention is implemented by the following technical solutions:

[0005] The present invention proposes a container cleaning machine, comprising a conveying device for conveying containers, wherein the conveying device is defined to have a conveying path, the conveying device has a carrying device for the container to be inverted with the container opening downward, and also includes at least one brushing area arranged on the container conveying path, in which at least one rotating brush for brushing the container is arranged around the container conveying path in the brushing area, and the brush is controlled by a driving device and can be relatively close to or away from the container on the conveying path, so that when the container is conveyed to the brushing area, the at least one brush is close to the container and performs rotational brushing on the container.

[0006] Among them, in order to improve the cleaning effect, the container cleaning machine also includes at least one rinsing area arranged on the container conveying path, and at least one liquid rotating nozzle that can be raised and lowered and controlled by a driving device is arranged in the rinsing area. The liquid rotating nozzle can be connected to liquid to rinse the inner and outer surfaces of the container.

[0007] Among them, in order to improve the cleaning effect, the container cleaning machine also includes at least one drying area arranged on the container conveying path, and the drying area is provided with at least one gas rotating nozzle that can be raised and lowered and controlled by a driving device. The gas rotating nozzle can be connected to gas to dry the inner and outer surfaces of the container.

[0008] In order to rinse and dry the container, the container cleaning machine further comprises at least one drying area arranged on the conveying path, wherein a drying device for drying the container is arranged around the container conveying path in the drying area.

[0009] Among them, in order not to affect the dried containers, increase the blowing area, and minimize the impact of the blown water droplets on the containers behind the conveying line, the drying device includes a hot air supply system, and a blowing device roughly facing the container. The blowing device is a roughly "V"-shaped wind knife, and its blowing direction is roughly from downstream to upstream of the conveying path, and at the same time biased to the left and / or right side of the conveying path.

[0010] In order to improve the cleaning degree and perform all-round cleaning, a top brush, a bottom brush and a side brush are respectively arranged above, below and on both sides of the container conveying path in the scrubbing area.

[0011] Among them, in order to improve the stability of cleaning by clamping the container, a first side brush and a second side brush are arranged on the left and right sides of the container conveying path in the brushing area. The first side brush has two side by side brushes, and the second side brush has one. The first side brush and the second side brush are roughly distributed in a triangle.

[0012] In order to further enhance the stability of the container during brushing, a positioning wheel is also provided in the brushing area. The positioning wheel is controlled by a driving device and can be relatively close to or away from the container on the conveying path, so that when the container enters the brushing area, the positioning wheel can abut against the outer surface of the container to limit the movement of the container.

[0013] Among them, in order to prevent the container from overturning or tipping over during the cleaning process and causing conveying failure, it also includes a height limiting device for pressing and limiting the top of the container. The height limiting device includes at least one pressure rod that extends approximately linearly on the conveying path and is located above the container. The pressure rod also has a height adjustment device, including a pressure rod swing arm connected to the pressure rod, the pressure rod swing arm is fixedly connected to a rotatable shaft and can swing with the rotation of the shaft, and an active swing arm is connected to the shaft. When the active swing arm swings, it drives the shaft to rotate, thereby driving the pressure rod swing arm to swing so that the pressure rod produces a height change to match the height of the container.

[0014] Among them, in order to prevent the container from turning over or tipping over during the cleaning process and causing conveying failure, it also includes a side limiting device for limiting the side of the container. The side limiting device is two rods that are relatively arranged on both sides of the barrel container conveying path and extend roughly linearly in the conveying direction. The spacing between the two side limiting devices is adjustable to match the width of the container, so as to limit the container between the two relatively arranged side limiting devices.

[0015] The present invention has the following beneficial effects: the present invention can clean and dry containers of various sizes and types, and can place the container with its opening upside down on a conveying device, which is beneficial to cleaning the inside of the container and draining the water, and is superior to other upright or sideways cleaning methods; the container can be cleaned and dried in all directions without dead angles, and has excellent cleaning ability. The rotation speed and clamping force of the scrubbing brush can be flexibly adjusted, and can be adjusted according to containers of different sizes and types; the container can be limited according to containers of different sizes to prevent the container from tipping over or turning over during the cleaning process. In general, the container cleaning machine provided in this embodiment improves the degree of automation of container cleaning, enhances the flexibility of handling various containers, and has excellent cleaning effect, and has a high promotion value.

[0037] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0038] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0039] See also Figure 1-Figure 2As shown, as a preferred embodiment of the present invention, a container cleaning machine is provided, which is particularly suitable for cleaning barrel containers, including a conveying device whose conveying direction is the direction T shown in the figure, and arranged in sequence from upstream to downstream of the conveying path of the conveying device: a high-pressure spray chamber A1, a brush cleaning chamber B, a high-pressure spray chamber A2, a high-temperature rinsing and disinfection chamber C, a hot air circulation drying chamber D and an air pressure high-pressure blow-drying chamber E. As shown in the figure, the barrel 100 is transported from upstream to downstream of the conveying path of the conveying device, passing through each chamber in sequence to complete automatic cleaning. In this embodiment, the conveying device is two parallel conveying chains 2. In order to position, receive and transport barrel containers, the conveying device also has a positioning ring seat 1 for the container to be inverted with its opening downward, see Figure 3-Figure 5 As shown, the positioning ring seat 1 is arranged between two parallel conveying chains 2, including two concentrically arranged first and second rings 12 and 13 that are mutually sleeved, the first and second rings 12 and 13 are positioned by connection, and the first and second rings 12 and 13 are arranged on the same plane; in order to avoid interference with the positioning and receiving of barrel containers, the connecting rod 11 is arranged below the first and second rings 12 and 13, and the connecting column 14 is perpendicular to the plane where the first and second rings 12 (or the second rings 13) are located; in order to increase the stability of the positioning ring seat 1 in receiving barrel containers, two connecting rods 11 are arranged in parallel, and the gap width between the two parallel connecting rods 11 is smaller than the minimum diameter of the second ring 13, so that the connecting rod 11 and the first and second rings 12 and 13 are all in the top view ( Figure 5 ) "intersect" and each has four connection points, which enhances the stability of the connection. However, in other embodiments, only one connecting rod 11 can be provided for connection; when two connecting rods 11 are provided, the connecting rod 11 can also have only two connection points with the second ring 13 (such as "tangent" in a top view).

[0040] The positioning ring seat 1 can be applied to containers of various types and sizes, such as Figure 6 The cylindrical barrel 100 with a narrow mouth is inserted upside down into the second ring 13 (or into the gap between the first ring 12 and the second ring 13, depending on the size of the barrel mouth 100a). The end face 100b of the barrel body abuts against the upper ends of the first ring 12 and the second ring 13 due to the weight of the barrel itself. Figure 7 The truncated cone-shaped barrel 200 is inserted with its barrel mouth 200a upside down into the second ring 13 (or into the gap between the first ring 12 and the second ring 13), and the truncated cone surface 200b of the barrel body rests on the second ring 13 (or the first ring 12) due to the weight of the barrel itself; Figure 8The truncated cone-shaped open barrel 300 is inverted and buckled with its barrel mouth 300a on the first ring 12 (when the barrel mouth 300a is small, it may also be buckled on the second ring 13), and the inner wall 300b of the barrel is pressed against the first ring 12 (or the second ring 13) due to the weight of the barrel itself. It should be noted that after the barrel container is placed on the positioning ring seat 1, since there is no circumferential limit, the barrel container can rotate freely.

[0041] See also Figure 2 , Fig. 9 and Fig.10 In order to prevent barrel containers from turning over or tipping over under the action of high-pressure water, brush rotation or wind during the cleaning process, resulting in conveying failure, a pressure rod 3 for limiting the barrel container in the height direction and side limit rods 4 are provided on the left and right sides of the conveying path, wherein:

[0042] Pressure rod 3: see Fig. 9 The pressure rod 3 is a rod member extending approximately linearly in the conveying direction of the conveying device (T direction in the figure). The pressure rod 3 is arranged above the barrel container and presses the barrel container downward by its own weight. Preferably, in order to enhance the stability of the pressing, the pressure rod 3 has two parallel branches. In order to facilitate the adjustment of the height of the pressure rod 3, the pressure rod 3 has a height adjustment component, including an active swing shaft 32, an active swing arm 31 and a linkage rod swing arm 33 fixedly connected to the active swing shaft 32 at both ends of the active swing shaft 32 (specifically, they can be fixedly connected by a key connection, interference fit or expansion connection, etc.), a pressure rod swing arm 35 is fixedly connected to the active swing shaft 32, and the linkage rod swing arm 33 is fixedly connected to the linkage rod 34, and the linkage rod 34 is additionally connected with multiple groups (two groups in this embodiment) of driven swing arms 36, and the driven swing arm 36 is also fixedly connected with the pressure rod swing arm 35. When the active swing arm 31 is swung, the active swing shaft 32 and the driven swing shaft 36 rotate to drive the pressure rod swing arm 35 to swing, so that the height of the pressure rod 3 connected to the pressure rod swing arm 35 changes. When the active swing arm 31 is fixed, the height of the pressure rod 3 is fixed, so the active swing arm 31 can be fixed by setting multiple blocks at different positions or other limiters, so as to flexibly adjust the height of the pressure rod 3. The active swing arm 31 can also be controlled by electric control to achieve the effect of automatic adjustment.

[0043] Side limit rod 4: The side limit rod 4 is a rod extending approximately linearly in the conveying direction of the conveying device (T direction in the figure). The side limit rod 4 is arranged on both sides of the conveying path of the barrel container. Fig.10 As shown, the two side limit rods 4 are close to each other to clamp the positioning barrel 100, completing the limit of the barrel 100. The side limit rods 4 are also adjustable, which can be as follows Fig.10As shown, the distance between the two oppositely disposed side limit rods 4 is controlled by the swing of the connecting rod 41, and the position of the side limit rod 4 can be fixed by locking at the rotation center 42 of the connecting rod 41. Similarly, the connecting rod 41 can also be set to be slidable, so as to control the distance between the two oppositely disposed side limit rods 4, such as replacing the original end of the connecting rod 41 at the rotation center 42 with a slider connected to a slide rail (the rotating pair becomes a sliding pair), and the slider can also be locked to fix the position of the side limit rod 4. By providing the side limit rod 4, the distance between the two side limit rods 4 can be adjusted according to containers of different sizes to perform side limiting. Similarly, the side limit rod 4 can also be automatically adjusted by electronic control.

[0044] The barrel 100 is steadily transferred to each cleaning process by the conveying chain 2, the positioning ring seat 1, the pressing rod 3 and the limiting rod 4, wherein:

[0045] High-pressure spray chamber A1: High-pressure spray chamber A1 is mainly used to flush the inner and outer surfaces of barrel containers. Fig.11 A high-pressure spray head 5 is arranged in the high-pressure spray chamber A1. To ensure that the barrel container is fully rinsed, there are several high-pressure spray heads 5 distributed on the left and right sides, above and below the conveying path of the barrel 100. The high-pressure spray head 5 arranged below the conveying path can spray into the inside of the barrel 100. Since the barrel 100 is inverted, the high-pressure spray head 5 can be arranged at the bottom of the barrel 100 to flush into the inside of the barrel 100. The water sprayed by the high-pressure spray head 5 then flows out of the barrel 100 by gravity, and at the same time takes away the dirt.

[0046] Brush cleaning chamber B: see Figure 12-14 The brush cleaning chamber B is provided with a first side brush 61 and a second side brush 62 on the left and right sides of the barrel 100 conveying path, and a top brush 63 and a bottom brush 64 are provided above and below the barrel 100 conveying path, respectively. The first side brush 61 and the second side brush 62 are used to brush the sides of the barrel 100, and the top brush 63 and the bottom brush 64 are used to brush the top and the bottom of the barrel 100, respectively. The first side brush 61, the second side brush 62, the top brush 63 and the bottom brush 64 are movable to be relatively close to or away from the barrel 100, as shown in the figure. Fig.13 As shown, the second side brush 62 has a rotating shaft 621 to drive the rotation of the second side brush 62. The rotating shaft 621 is connected to the driving shaft 622 by a bearing. The driving shaft 622 can rotate to drive the second side brush 62 to swing. The driving shaft 622 can also be configured to be movable to drive the second side brush 62 to move. Fig.14As shown, in the present embodiment, two groups of second side brushes 62 are provided, and both groups of second side brushes 62 are swingable to get closer to or away from the bucket 100, and one group of first side brushes 61 is provided, and the first side brush 61 can be moved forward and backward to get closer to or away from the bucket 100, and the first side brush 61 and the two groups of second side brushes 62 are roughly distributed in a triangle to enhance the stability of clamping the bucket 100 when scrubbing the bucket 100. The top brush 63 and the bottom brush 64 can also be configured to be movable up and down to get closer to or away from the bucket 100. In order to better position the bucket 100 and maintain the stability of the bucket 100 during scrubbing, positioning wheels 65 are further provided on both sides of the first side brush, and the positioning wheels 65 are also swingable (can be provided with a drive shaft like the second side brush 62, and its swinging motion is as shown in the figure). Fig.15 As shown). After the container cleaning and drying machine senses that the barrel 100 has entered the brush cleaning chamber B (obviously, a sensor can be set to sense the conveying position of the barrel 100), the first side brush 61, the second side brush 62, the top brush 63 and the bottom brush 64 are started to approach the clamping barrel 100, and the brushes are rotated to scrub the sides, top and bottom of the barrel 100. Since the positioning ring seat 1 does not have a circumferential limit on the barrel 100, the barrel 100 will also be driven by the brush to rotate during the process of brushing the barrel 100, thereby achieving an all-round scrubbing effect. In other embodiments, the first side brush 61 can also be replaced by two groups of brushes that swing close to the barrel 100, and the second side brush 62 can naturally also use a mobile movement mode, as long as the above-mentioned function of clamping the barrel container and scrubbing can be achieved. The rotation and movement of the brush are controllable, such as the commonly used motor to drive the rotation and movement of the brush, and the control of the rotation speed, swing and movement amount (i.e., the clamping force of the barrel container) or the brushing time of the brush by controlling the corresponding parameters of the motor are all obvious and achievable for those skilled in the art. In this embodiment, since the barrel 100 is inverted, the dirt scrubbed by the brush is not easy to enter the interior of the barrel 100.

[0047] High-pressure spray chamber A2: The structure of the high-pressure spray chamber A2 is the same as that of the high-pressure spray chamber A1. It is mainly used to rinse barrel containers again after they have been scrubbed to remove any residual substances that may have been scrubbed off.

[0048] High temperature rinsing and disinfection chamber C: High temperature rinsing and disinfection chamber C is mainly used to clean the inside of barrel containers. Figure 16-Figure 18An explosive rotary ejector 7 which can extend into the barrel 100 is provided in the high-temperature rinsing and disinfecting chamber C. The explosive rotary ejector 7 includes a columnar ejector body 77. A wide-angle nozzle 74 is provided on the ejector body 77 to scatter the liquid (or gas). A straight columnar nozzle 75 is also provided to eject the liquid (or gas). A rotating bearing 76 is provided at the lower end of the ejector body 77. During the ejection process of the ejector body 77, the ejector body 77 affected by the ejection reaction force rotates in the rotating bearing 76 by itself, thereby achieving a 360° all-round ejection effect. The explosive rotary ejector 7 is liftable. For example, in the present embodiment, two relatively arranged cylinders 73 can be used to control the lifting and lowering of the explosive rotary ejector 7. See FIG. Fig.17 , the explosive rotary ejector 7 is fixedly mounted on the mounting seat 71, and the mounting seat 71 is connected to the piston rods of the two cylinders 73. When the cylinder 73 is actuated, the explosive rotary ejector 7 can be driven to rise and fall. Of course, the cylinder 3 can also be replaced by other servo mechanisms, such as a linear stepping motor or a hydraulic cylinder. The explosive rotary ejector 7 that can be raised and lowered and can spray 360° in all directions can ensure a cleaning effect without dead angles. The explosive rotary ejector 7 is connected to high-temperature disinfectant water and / or clean water through the pipeline 72. The high-temperature disinfectant water is used to rinse the inside of the barrel 100 at high temperature, and the clean water is used to rinse the inside of the barrel 100. The implementation method includes but is not limited to: 1. The explosive rotary ejector 7 is connected to two passages of high-temperature disinfectant water and clean water at the same time. The valve of the high-temperature disinfectant water passage is first opened to spray the high-temperature disinfectant water, and then the clean water passage is opened (the high-temperature disinfectant water passage is closed at the same time) to rinse; 2. Two high-temperature rinsing and disinfection chambers C1 and C2 are provided, and the first chamber C1 only sprays high-temperature disinfectant water, and the second chamber C2 only sprays clean water. The explosive rotary ejector 7 can also be connected to gas to blow dry the inside of the barrel 100 (i.e., the air pressure high pressure blowing chamber E described below). In other embodiments, the explosive rotary ejector 7 can also be arranged outside the barrel container to clean any part of the barrel container (especially the dead corners, grooves and pouring mouths that are difficult to clean). Also, because the barrel 100 is inverted, the liquid ejected by the explosive rotary ejector 7 will not accumulate inside the barrel 100, but will flow out by itself under the influence of gravity, taking away the dirt.

[0049] Hot air circulation drying chamber D: see Fig.19The hot air circulation drying chamber D is a chamber for drying the barrel 100. The hot air circulation drying chamber D is provided with a top wind knife 81 and a bottom wind knife 83 above and below the conveying path of the barrel 100, respectively. The hot air circulation drying chamber D is provided with side wind knives 82 on both sides of the conveying path of the barrel 100. The fan supplies circulating hot air, and the barrel 100 is gradually dried through the top wind knife 81, the bottom wind knife 83 and the side wind knife 82. The blowing direction of the wind knife is roughly from the downstream to the upstream of the conveying path to avoid blowing water droplets to the previous barrel 100 that has completed the drying work, and preferably, in this embodiment, the top wind knife 81 and the bottom wind knife 83 are V-shaped wind knives as shown in the figure (see Fig. 20 and Fig.21 ), the blowing angles of the top wind knife 81 and the bottom wind knife 83 are at a certain angle to the conveying direction of the barrel 100 (the T direction in the figure), so that the water drops on the barrel 100 are scattered as much as possible to the two sides of the conveying direction, while avoiding affecting the previous barrel 100 and minimizing the impact on the next barrel 100, which is conducive to improving the drying effect on the surface of barrel containers. At the same time, the design of the V-shaped wind knife can also effectively increase the blowing area. Multiple groups of top wind knives 81, bottom wind knives 83 and side wind knives 82 can be set.

[0050] Air pressure high-pressure drying chamber E: The air pressure high-pressure drying chamber E is provided with the same explosive rotary ejector 7 as that in the high-temperature rinsing and disinfection chamber C, except that the explosive rotary ejector 7 in the air pressure high-pressure drying chamber E is connected with compressed air (or other gases such as nitrogen) to fully dry the inside of the barrel 100. After being dried in the hot air circulation drying chamber D, the inside of the barrel container is fully dried in the air pressure high-pressure drying chamber E, so that the barrel container can be completely dried.

[0051] In other embodiments, the setting order and number of processes of the high-pressure spray chamber A1, the brush cleaning chamber B, the high-temperature rinsing and disinfection chamber C, the hot air circulation drying chamber D and the air pressure high-pressure blow-drying chamber E are not fixed. For example, in this embodiment, two cleaning processes of high-pressure spray chambers A1 and A2 are adopted. In other embodiments, several cleaning processes of the brush cleaning chamber B, several drying processes of the hot air circulation drying chamber D, and so on can be adopted.

[0052] In this embodiment, sensors for sensing the position of the container are provided in each chamber to facilitate the control of the operation of each chamber. Based on the above technical solution, it is easy for a person skilled in the art to realize the automatic cleaning effect of this embodiment by using electric control technology.

[0053] This embodiment uses a barrel-type container to illustrate the solution, which is only for the purpose of facilitating the understanding of the solution. In fact, the container cleaning and drying machine provided in this embodiment can also be used to clean other containers, such as basins, cans, etc.

[0054] The advantages of the container washing and drying machine provided in this embodiment are:

[0055] 1. Through the design of the positioning ring seat 1, various containers can be cleaned and dried, with strong adaptability, and the container can be inverted on the conveying device with its opening. The inverted container is conducive to cleaning the inside of the container and discharging water, which is better than other cleaning methods of placing it upright or lying on its side.

[0056] 2. Through the design of the liftable explosion rotary ejector 7, the container can be cleaned and dried in all directions without dead angles, and the cleaning ability is excellent.

[0057] 3. Through the design of the movable brush, the rotation speed and clamping force of the brush can be flexibly adjusted, and can be adjusted according to containers of different sizes and types.

[0058] 4. Through the design of the pressure rod 3 and the side limiting rod 4, they can be adjusted according to containers of different sizes, so as to limit the container and prevent the container from tipping over or turning over during the cleaning process.

[0059] 5. In general, the container cleaning and drying machine provided in this embodiment improves the automation level of container cleaning, enhances the flexibility of handling various containers, and has excellent cleaning effect and high promotion value.
