Description

Technical Field

[0001] The present application relates to the technical field of can conveying equipment, and in particular to a single-channel air conveying equipment for cans. Background Art

[0002] Since empty cans are relatively light, they are generally transported by air conveying lines, which are interspersed in various links of the can production line.

[0003] After screening or rejection, cans need to be transported in multiple rows or multiple routes into one route. In the process of converting to single-route transportation, it is necessary not only to reduce the occurrence of misalignment and falling of empty cans, but also to ensure the efficiency of the single-route passage of cans.

[0004] In the conveyor belt conveyor line, there are many types of single-channel conversion conveyor lines, which basically involve differential transportation. However, unlike the air conveyor line, the air conveyor line cannot change the conveying speed of different areas through different motors and other transmission structures. In addition, the air conveyor line itself is fast when conveying cans. When changing lanes, cans will collide, which will not only reduce the quality of the cans themselves, but also cause the cans to detach or overturn, thus affecting the transportation of the entire can air conveyor line.

[0005] Therefore, the existing air conveying line has the following problems in the conversion mode from multi-channel to single-channel cans:

[0006] The air conveying line has a high conveying speed. When the guide plate is used to change the width of the conveying path during the single-channel conversion process, the cans may collide, dent, or fall down.

[0007] It is difficult for pneumatic conveying lines to achieve segmented differential transmission and single-channel transportation like conveyor belts. Summary of the invention

[0008] In order to improve the defects of low efficiency in converting multi-channel can conveying to single-channel can conveying and easy collision or knocking of cans on the conveying line by air conveying lines, the present application provides a single-channel can air conveying equipment.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-6 This application is described in further detail.

[0046] The embodiment of the present application discloses a single-channel air conveying device for cans.

[0047] refer to Figure 1 and Figure 2The single-channel air conveying equipment for cans includes a machine body 1, a guide part 2, a channel plate 3 and a bellows 4. The guide part 2 is installed on the top of the machine body 1, for multiple cans to enter side by side from a vertical state and move out in a laid-down state, and the entrance of the guide part 2 is connected with the end of the can air conveying belt. There are two channel plates 3, which are arranged opposite to each other, installed on the machine body 1, and located directly below the guide part 2. The cans discharged from the bottom of the guide part 2 will move to the position between the two channel plates 3 and the end faces the channel plate 3 and abuts against the channel plate 3. A conveying path 31 is provided on the channel plate 3, and the conveying path 31 is an inverted "U" shape, that is, the U-shaped opening faces the horizontal direction. The conveying path 31 is divided into two horizontal parts, an upper and lower horizontal part and a bent end at the middle bend, and the conveying directions of the upper and lower parts are opposite. The upper half of the conveying path 31 is located at the top of the channel plate 3 and is located directly below the outlet of the guide part 2. The upper half of the conveying path 31 directly facing the guide part 2 occupies half of the opening below the guide part 2. The lower half of the conveying path 31 is located at the bottom of the channel plate 3. The conveying path 31 is used to convey the cans discharged from the guide part 2 downward in a single row. The channel plate 3 is provided with anti-slip plates 37 at the outer side of the bent end of the conveying path 31 and at the bottom of the lower half along the contour of the conveying path 31. The distance between the two anti-slip plates 37 is less than the height of the cans placed upright, thereby preventing the cans from escaping from the conveying plate area during the passage.

[0048] Combination Figure 2 and Figure 3 A first air hole 32 inclined toward the conveying direction of the conveying path 31 is provided on the channel plate 3 at a position directly opposite to the conveying path 31. The bellows 4 is installed on the body 1, located on both sides of the channel plate 3, and is connected to the fan air outlet duct arranged on the top of the body 1, and is used to blow air to the first air hole 32. In the middle of the channel plate 3, a plurality of second air holes 33 inclined upward are provided at a position above the conveying path 31 in the lower half. The bellows 4 is connected to the second air holes 33, and the cans between the upper and lower halves of the conveying path 31 are blown upward, and the cans are blown into the conveying path 31 in the upper half. A plurality of air holes 36 are provided in the middle of the channel plate 3, and are used to lead the airflow blown in between the channel plates 3 outward.

[0049] The cans on the air conveying line abut against each other and enter the guide part 2 side by side, and enter the conveying path 31 under the guidance of the guide part 2. After entering the upper part of the conveying path 31, the cans move in rows along the conveying path 31 under the action of the wind blown out by the first air hole 32. Some of the cans pass through the upper part of the conveying path 31 and enter the middle part of the U-shaped area of ​​the conveying path 31, and move upward under the action of the second air hole 33, and abut against the cans above, and then abut against the cans in the upper and lower areas of the upper part of the conveying path 31, thereby improving the efficiency and stability of the can replenishment in the conveying path 31, and also realizing the function of converting multiple routes to a single route on the can air conveying line, and ensuring the conveying efficiency of the cans.

[0050] refer to Figure 4 and Figure 5 The bellows 4 includes a conveying shell 41, a top blowing shell 42 and a connecting shell 43. The top blowing shell 42 and the conveying shell 41 are installed on the channel plate 3, and are located on the opposite side of the two channel plates 3. The conveying shell 41 is distributed along the conveying path 31 and covers the first air hole 32 therein. The top blowing shell 42 covers the second air hole 33 therein. The connecting shell 43 is installed on the body 1, and the connecting shell 43 is connected to the conveying shell 41. The connecting shell 43 is also connected to the top blowing shell 42, and is connected to the air outlet duct of the fan at the top of the body 1. A plurality of dampers 411 are slidably connected at the connection ports of the connecting shell 43 and the conveying shell 41 and the top blowing shell 42, and the connecting shell 43 is installed with a control component 5 for controlling the opening and closing degree of the damper 411. The air flow in the corresponding area is controlled by controlling the opening size of the corresponding damper 411 through the control component 5.

[0051] The control assembly 5 includes an adjusting screw 51 and a seesaw 52, ​​and strip holes are provided at both ends of the seesaw 52. The adjusting screw 51 is threadedly connected to the conveying housing 41, and the other end of the adjusting screw 51 is rotationally connected to the corresponding damper 411, and the axial direction of the adjusting screw 51 is parallel to the sliding direction of the damper 411 to which it is rotationally connected. The top of the damper 411 at the corner of the conveying housing 41 is sleeved and slidably connected to the end of the seesaw 52, ​​the middle of the seesaw 52 is rotationally connected to the conveying housing 41, the adjusting screw 51 is rotationally connected to the connecting housing 43, and the bottom end is sleeved and slidably connected to the other end of the seesaw 52. Then, the degree of opening of the corresponding damper 411 can be achieved by rotating the adjusting screw 51.

[0052] refer to Figure 2 and Figure 3, guide plates 6 are fixedly arranged on the opposite side walls of the two channel plates 3. The guide plates 6 are located on the side opposite to the conveying direction of the conveying path 31 directly below the guide portion 2, i.e., away from the bent end of the conveying path 31. The guide plates 6 are arranged obliquely toward the side wall of the bent end of the conveying path 31, so that the empty cans abutted thereon can move toward the middle of the channel plate 3. An inner inclined groove 61 is provided inwardly at the end of the inclined surface of the guide plate 6, and the second air hole 33 is located below the plane where the bottom end of the inclined surface of the channel plate 3 is located. The inner inclined groove 61 is also provided with a second air hole 33, wherein the second air hole 33 of the inner inclined groove 61 is arranged obliquely upward, and is used to blow the cans at the inner inclined groove 61 obliquely upward away from the inner inclined groove 61. Except for the second air holes 33 at the inner inclined groove 61, all of them are covered by the top blowing shell 42. The channel plate 3 is also provided with a sub-shell 34, which is adjacent to the top blowing shell 42, and the sub-shell 34 covers the second air holes 33 in the inner inclined groove 61 area. The auxiliary housing 34 is connected to the communication housing 43 and a damper 411 is provided at the connection point. The damper 411 is driven to open and close by the adjusting screw 51 .

[0053] A blow-off shell 62 is fixedly provided at the bottom of the guide plate 6 at the end of the inner chute 61, and the machine body 1 is also fixedly provided with a blow-off box 11, which is adjacent to the auxiliary shell 34. The blow-off box 11 is connected to the blow-off shell 62, and the connecting shell 43 is connected to the blow-off box 11. The air outlet of the blow-off shell 62 faces the same conveying direction as the conveying path 31 directly below the guide portion 2, that is, the same conveying direction as the upper half of the conveying path 31.

[0054] The channel plate 3 is rotatably connected to a horizontally arranged rejection rod 35 at the bottom end of the inner inclined groove 61, and the rejection rod 35 is driven to rotate by a motor. The rejection rod 35 is located below the blow-off shell 62, and the distance between the rejection rod 35 and the top of the can in the lower conveying path 31 is not enough for the can to pass through, and the rejection rod 35 can move the abutted can toward the air outlet of the blow-off shell 62.

[0055] Some of the cans that fall from the upper conveying path 31 will abut against the guide plate 6 and move under the guidance of the inclined surface of the guide plate 6. The setting of the guide plate 6 can effectively reduce the probability of cans leaking from the other side of the channel plate 3, and gather the cans in the middle, so that the cans are pressed upward under the blowing of the second air hole 33, thereby achieving stable can replenishment. The setting of the inner chute 61 cooperates with the second air hole 33 in the area of ​​the blow-off shell 62 and the inner chute 61, so that no cans will stay in the area of ​​the inner chute 61. The setting of the rejection rotating rod 35 can remove the cans that are offset upward in the lower conveying path 31 from the conveying path 31 to the area of ​​the inner chute 61 by rotating, and blow them out of the inner chute 61 under the action of the blow-off shell 62 and the second air hole 33 of the inner chute 61. The setting of the inner chute 61 provides a temporary stay space for the cans raised by the rejection rotating rod 35 after peeling. This structure can cooperate with the upper part of the conveying path 31 so that the rejected cans can be lined up under the upper part of the conveying path 31 and re-entered into the conveying path 31 for conveyance, thereby improving the efficiency of high-speed and stable passage of cans after converting from multiple paths to a single path.

[0056] refer to Figure 6 The guide part 2 includes a first arc shell 21, a second arc shell 22 and a connecting rod 23. The first arc shell 21 and the second arc shell 22 are both installed on the top of the body 1, and the straight line where the arc center is located is collinear. There are multiple connecting rods 23, which are installed on the side walls of the first arc shell 21 and the second arc shell 22 at the same time to connect and reinforce the second arc shell 22 and the second arc shell 22. The top ends of the first arc shell 21 and the second arc shell 22 are both horizontally oriented, and the bottom ends are both vertically oriented. The cans can maintain a vertical state and enter between the first arc shell 21 and the second arc shell 22 side by side and maintain a laid-down state to enter the conveying path 31. The space between the first arc shell 21 and the second arc shell 22 is a guide section, and guide rail plates 211 are fixed on both sides of the first arc shell 21 and the second arc shell 22 in the guide section, which are used to abut against the side walls of the cans to prevent the cans from escaping from both sides of the guide section. The ends of the air delivery lines that enable multiple rows of cans to move together are connected to the horizontal ports of the first arc shell 21 and the second arc shell 22 to deliver the cans into the guide section.

[0057] The implementation principle of a single-channel air conveying device for cans in the embodiment of the present application is as follows: the cans are moved side by side from the air conveying line to the space between the first arc shell 21 and the second arc shell 22, and the cans are laid down to enter the upper half of the conveying path 31, wherein some of the cans fall below the upper half of the conveying path 31, and some of the cans move along the conveying path 31 under the action of the first air hole 32 in the conveying path 31. The cans that fall below the upper half of the conveying path 31 move upward under the action of the second air hole 33 and abut against the cans in the upper half of the conveying path 31, and squeeze into the conveying path 31 together with the cans in the guide part 2. The cans that move to the lower half of the conveying path 31 and deflect upward are peeled off from the inner chute 61 area after abutting against the rejection rotating rod 35, and move upward. This can achieve high-speed and stable operation of converting multiple cans into a single path, and automatically remove cans with offset positions to reduce the probability of can blockage, and automatically move the rejected cans to the lower part of the upper half of the conveying path 31 for can replenishment, thereby reducing the collision of cans during the single-path conversion process and improving the quality of the cans.

[0058] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
