[0001] The invention relates to the technical field of preform tipping equipment, and in particular to a cover bucket structure of a preform tipping machine with a blocking mechanism and a use method thereof. Background Art

[0002] In automated filling production lines such as bottled water, preforms and bottle caps and other accessories need to be continuously supplied to the production line. They are the core components of the preform tipping machine, which is usually composed of multiple tipping units to accommodate and flip the preforms. The shape and size of the tipping bucket are designed according to the specifications of the preforms to ensure that the preforms can be stably placed in the tipping bucket and flipped smoothly.

[0003] Among them, most of the above preforms are thin plastic products. When a large number of preforms are filled into the cover bucket, the preforms at the bottom will be dented due to the pressure of the top preforms, resulting in incomplete preforms and affecting the subsequent use of the preforms. In view of the above problems, the following solutions are proposed. Summary of the invention

[0008] Preferably, the limiting assembly further comprises a torsion spring 1 fixedly connected to the inner wall of the mounting hole, one end of the torsion spring 1 away from the mounting hole is fixedly connected to the inner wall of the right-angle groove, and a discharge assembly is fixedly connected to the side wall of the cover bucket. Before use, the mounting bracket is installed at the desired position, and when the external conveyor belt transfers the bottle blank to the inside of the cover bucket, the bottle blank falls from top to bottom inside the cover bucket, and when the falling bottle blank contacts the top of the rotating square plate, the weight of the bottle blank will force the rotating square plate to rotate downward with the torsion spring 1 as the center, presenting a Figure 5 In the middle G state, part of the preform will fall to the bottom of the cover.

[0009] Preferably, the discharge assembly includes an air pressure box connected to the side wall of the cover bucket, and five air pressure shrink tubes are connected to the side of the air pressure box near the inner wall of the cover bucket. One end of the five air pressure shrink tubes is fixedly connected to the top of the rotating plate. As the material at the bottom of the cover bucket increases, the bottle blanks at the bottom of the rotating plate will be at the bottom of the rotating square plate, thereby limiting the rotation of the rotating square plate, and the excess bottle blanks will stay at the top of the rotating plate, presenting a Figure 5 In the middle H state, during this process, the excess bottle blanks will stay on the top of the rotating plate, and the rotating plate provides most of the supporting force for the bottle blanks above itself. Through the application of the above components, the bottle blanks inside the cover bucket are divided into two layers to avoid excessive pressure on the bottom, which will cause the bottom bottle blanks to sag.

[0010] Preferably, the discharge assembly also includes a transmission pipe connected to the bottom of the air pressure box 1, the side wall of the transmission pipe is fixedly connected to the outer wall of the cover bucket, and the end of the transmission pipe away from the air pressure box 1 is connected to the air pressure box 2. By utilizing the above-mentioned feature that the bottle blanks are divided into upper and lower layers, a rotating frame and a limit plate are arranged inside the equipment. After the filling of the cover bucket is completed, the staff can turn on the power of the motor, and the motor drives the cover bucket to rotate through the driving column, so that the equipment can be Figure 2 The status changes to Figure 1 status.

[0011] Preferably, the discharge assembly also includes an air pressure shrinkage tube 2 which is connected through the air pressure shrinkage tube 2 near the inner wall of the cover bucket, the outer wall of the air pressure box 2 is fixedly connected to the inner wall of the through hole of the cover bucket, the end of the air pressure shrinkage tube 2 away from the air pressure shrinkage tube 2 is fixedly connected to a push plate, the side wall of the push plate is slidably connected to the inner wall of the cover bucket, the top of the cover bucket is fixedly connected to a buffer assembly, and as the angle of the cover bucket itself changes, the rotating plate is affected by gravity and will rotate with the rotating frame as the rotating plate, so that the rotating plate moves from Figure 7 Towards Figure 8 During this process, a gap will be formed between the rotating plate and the cover bucket, so that the preforms originally at the bottom of the cover bucket can flow out from the outlet of the cover bucket through the above gap. When the rotating plate does not swing, the preforms on the top of the rotating plate are affected by the tilt angle and flow out slowly. After the rotating plate completes the angle change, the gap between the rotating plate and the cover bucket also synchronously limits the speed of the bottle flowing out. Through the application of the above components, the speed and flow rate of the bottle preforms flowing out can be effectively controlled to avoid the internal bottle preforms flowing out at once after the equipment is tilted, causing the subsequent equipment to be blocked.

[0012] Preferably, the buffer assembly includes a fixed frame fixedly connected to the top of the cover bucket, an end of the fixed frame away from the cover bucket is fixedly connected to an arc plate, and the inclined surface of the cover bucket is fixedly connected to a sliding track. Utilizing the characteristic of the angle change of the above-mentioned rotating plate, a discharge assembly is arranged inside the equipment. When the angle of the rotating plate changes, the rotating plate will squeeze the air pressure shrink tube one, so that the gas of the five air pressure shrink tubes one is transmitted to the inside of the air pressure box one and the air pressure shrink tube one, and finally enters the inside of the air pressure shrink tube two. As the gas inside the air pressure shrink tube two increases, the air pressure shrink tube two will extend, and the extended push plate will drive the push plate to move outward, and the outward-moving push plate will contact multiple bottle blanks. Through the application of the above-mentioned components, it is avoided that part of the bottle blanks are inside the cover bucket, causing material jamming inside the cover bucket.

[0014] Preferably, a spring 1 is fixedly connected to the side wall of the U-shaped slide, and one end of the spring 1 away from the U-shaped slide is fixedly connected to the end of the sliding track away from the fixed frame. By utilizing the above-mentioned characteristic that the cover bucket generates an inclination angle, a buffer component is arranged inside the device. When the cover bucket is tilted, as the center of gravity angle of the U-shaped slide changes, the device presents a Figure 10 At this time, the U-shaped slide will slide outward along the inner wall of the sliding track, and the U-shaped slide will drive the fixed rod and the square rotating plate to slide outward synchronously. When the square rotating plate is no longer in contact with the inclined surface of the cover bucket, the square rotating plate will swing downward with the connection point as the center, so that the square rotating plate moves from Figure 10 The state Z in the middle is changed to the state Y, and at this time, the bottle blanks flowing out of the cover bucket will first flow out along the arc surface of the arc plate and contact the side wall of the square rotating plate, and the square rotating plate will absorb the excess power of the bottle blanks flowing out, so that the bottle blanks fall downward through the gap between the arc plate and the square rotating plate. Through the application of the above components, it is avoided that the initial speed of the cover bucket flowing out of the cover bucket is too fast, resulting in the bottle blanks of the plastic products colliding with each other after falling, resulting in dents on the outer wall of the bottle blanks, affecting subsequent use.

[0015] A method for using a cover bucket structure of a preform tipping machine with a blocking mechanism comprises the following steps:

[0016] S1: Putting the preform into the cover: Before use, install the mounting bracket at the required position. When the external conveyor belt transfers the preform to the inside of the cover bucket, the preform falls from top to bottom inside the cover bucket;

[0017] S2: Protecting the preform: When the falling preform contacts the top of the rotating square plate, the weight of the preform will force the rotating square plate to rotate downward with torsion spring 1 as the center, and part of the preform will fall to the bottom of the cover bucket, and the excess preform will stay on the top of the rotating plate.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention aims to solve the problem that too many preforms will be stacked and cause the bottom preforms to be sunken. A blocking mechanism and a limiting assembly are arranged inside the device. Before use, the mounting bracket is installed at the desired position. When the external conveyor belt conveys the preforms to the inside of the cover bucket, the preforms fall from top to bottom inside the cover bucket. When the falling preforms contact the top of the rotating square plate, the weight of the preforms will force the rotating square plate to rotate downward with the torsion spring as the center, presenting the following situation: Figure 5 In the middle G state, part of the preform will fall to the bottom of the cover bucket, and as the material at the bottom of the cover bucket increases, the preform at the bottom of the rotating plate will be at the bottom of the rotating square plate, thereby limiting the rotation of the rotating square plate, and the excess preform will stay on the top of the rotating plate, showing as follows Figure 5 In the middle H state, during this process, the excess bottle blanks will stay on the top of the rotating plate, and the rotating plate provides most of the supporting force for the bottle blanks above itself. Through the application of the above components, the bottle blanks inside the cover bucket are divided into two layers to avoid excessive pressure on the bottom, which will cause the bottom bottle blanks to sag.

[0020] (2) The present invention utilizes the above-mentioned feature that the finished bottle blanks are divided into two layers, an upper layer and an lower layer, and a rotating frame and a limit plate are arranged inside the equipment. After the filling of the cap bucket is completed, the staff can turn on the power of the motor, and the motor drives the cap bucket to rotate through the driving column, so that the equipment can be rotated. Figure 2 The status changes to Figure 1 As the angle of the cover bucket changes, the rotating plate is affected by gravity and rotates with the rotating frame as the rotating plate. Figure 7 Towards Figure 8 During this process, a gap will be formed between the rotating plate and the cover bucket, so that the preforms originally at the bottom of the cover bucket can flow out from the outlet of the cover bucket through the above gap. When the rotating plate does not swing, the preforms on the top of the rotating plate are affected by the tilt angle and flow out slowly. After the rotating plate completes the angle change, the gap between the rotating plate and the cover bucket also synchronously limits the speed of the bottle flowing out. Through the application of the above components, the speed and flow rate of the bottle preforms flowing out can be effectively controlled to avoid the internal bottle preforms flowing out at once after the equipment is tilted, causing the subsequent equipment to be blocked.

[0021] (3) The present invention utilizes the characteristic of the angle change of the above-mentioned rotating plate, and a discharge assembly is arranged inside the equipment. When the angle of the rotating plate changes, the rotating plate will squeeze the air pressure shrink tube 1, so that the gas of the five air pressure shrink tubes 1 is transmitted to the inside of the air pressure box 2 through the air pressure box 1 and the air pressure shrink tube 1, and finally enters the inside of the air pressure shrink tube 2. As the gas inside the air pressure shrink tube 2 increases, the air pressure shrink tube 2 will extend, and the extended push plate will drive the push plate to move outward, and the outward-moving push plate will contact multiple bottle blanks. Through the application of the above-mentioned assembly, it is avoided that part of the bottle blanks are inside the cover bucket, causing material jamming inside the cover bucket.

[0022] (4) The present invention utilizes the above-mentioned characteristic that the cover bucket generates an inclined angle, and a buffer component is arranged inside the device. When the cover bucket is tilted, as the angle of the center of gravity of the U-shaped slide changes, the following is presented: Figure 10 At this time, the U-shaped slide will slide outward along the inner wall of the sliding track, and the U-shaped slide will drive the fixed rod and the square rotating plate to slide outward synchronously. When the square rotating plate is no longer in contact with the inclined surface of the cover bucket, the square rotating plate will swing downward with the connection point as the center, so that the square rotating plate moves from Figure 10 The state Z in the middle is changed to the state Y, and at this time, the bottle blanks flowing out of the cover bucket will first flow out along the arc surface of the arc plate and contact the side wall of the square rotating plate, and the square rotating plate will absorb the excess power of the bottle blanks flowing out, so that the bottle blanks fall downward through the gap between the arc plate and the square rotating plate. Through the application of the above components, it is avoided that the initial speed of the cover bucket flowing out of the cover bucket is too fast, resulting in the bottle blanks of the plastic products colliding with each other after falling, resulting in dents on the outer wall of the bottle blanks, affecting subsequent use.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] For example, see Figure 1 - Figure 6 The present invention is a cover bucket structure of a preform tipping machine with a blocking mechanism, comprising a mounting bracket 1, a motor 11 is fixedly connected to the side wall of the mounting bracket 1, a driving column 12 is fixedly connected to the output shaft of the motor 11, and a cover bucket 13 is fixedly connected to the outer wall of the driving column 12;

[0039] The blocking mechanism 2 includes a rotating plate 21, a rotating frame 22 for limiting the turning direction of the rotating plate 21, a limit plate 23, and a limiting component 3 for controlling the feeding and discharging of the rotating plate 21;

[0040] The side wall of the rotating plate 21 is rotatably connected to the inner wall of the rotating frame 22 . A limiting plate 23 is fixedly connected to the inner wall of the rotating frame 22 . The top of the limiting plate 23 contacts the bottom of the rotating plate 21 .

[0041] The limiting component 3 includes five through-hole grooves 31 opened on the top of the rotating plate 21, and a plurality of right-angle grooves 32 are opened at the bottom of the five through-hole grooves 31. A rotating square plate 33 is rotatably connected to the inner wall of the plurality of right-angle grooves 32, and mounting holes 35 are opened at both ends of the rotating square plate 33.

[0042] The limiting component 3 also includes a torsion spring 34 fixedly connected to the inner wall of the mounting hole 35, and one end of the torsion spring 34 away from the mounting hole 35 is fixedly connected to the inner wall of the right-angle groove 32. A discharge component 4 is fixedly connected to the side wall of the cover bucket 13. Before use, the mounting bracket 1 is installed at the desired position. When the external conveyor belt transfers the bottle blank to the inside of the cover bucket 13, the bottle blank falls from top to bottom in the cover bucket 13. When the falling bottle blank contacts the top of the rotating square plate 33, the weight of the bottle blank will force the rotating square plate 33 to rotate downward with the torsion spring 34 as the center, presenting the following Figure 5 In the middle G state, part of the preform will fall to the inner bottom of the cover hopper 13.

[0043] For example 2, please refer to Figure 7 - Fig.11 The present invention is a cover bucket structure of a preform tipping machine with a blocking mechanism. On the basis of the first embodiment, the discharge assembly 4 includes an air pressure box 41 connected to the side wall of the cover bucket 13. One side of the air pressure box 41 close to the inner wall of the cover bucket 13 is connected to five air pressure shrink tubes 42. One end of the five air pressure shrink tubes 42 is fixedly connected to the top of the rotating plate 21. As the material at the bottom of the cover bucket 13 increases, the bottle blanks at the bottom of the rotating plate 21 will be at the bottom of the rotating square plate 33, thereby limiting the rotation of the rotating square plate 33, and the excess bottle blanks will stay on the top of the rotating plate 21, presenting as shown in the figure. Figure 5 In the middle H state, during this process, the excess bottle blanks will stay on the top of the rotating plate 21, and the rotating plate 21 provides most of the supporting force for the bottle blanks above itself. Through the application of the above components, the bottle blanks inside the cover bucket 13 are divided into two layers to avoid excessive pressure on the bottom, which will cause the bottom bottle blanks to sag.

[0044] The discharge assembly 4 also includes a transmission pipe 43 connected to the bottom of the air pressure box 1 41, the side wall of the transmission pipe 43 is fixedly connected to the outer wall of the cover bucket 13, and the end of the transmission pipe 43 away from the air pressure box 1 41 is connected to the air pressure box 2 44. By utilizing the above-mentioned feature of dividing the preform into two layers, a rotating frame 22 and a limit plate 23 are arranged inside the equipment. After the filling of the cover bucket 13 is completed, the staff can turn on the power of the motor 11, and the motor 11 drives the cover bucket 13 to rotate through the driving column 12, so that the equipment can be turned on. Figure 2 The status changes to Figure 1 status.

[0045] The discharge assembly 4 also includes a second air pressure shrink tube 45 which is connected through the second air pressure shrink tube 45 near the inner wall of the cover bucket 13. The outer wall of the second air pressure box 44 is fixedly connected to the inner wall of the through hole of the cover bucket 13. The end of the second air pressure shrink tube 45 away from the second air pressure shrink tube 45 is fixedly connected to a push plate 46. The side wall of the push plate 46 is slidably connected to the inner wall of the cover bucket 13. The top of the cover bucket 13 is fixedly connected to a buffer assembly 5. As the angle of the cover bucket 13 changes, the rotating plate 21 is affected by gravity and rotates with the rotating frame 22 as the rotating plate 21, so that the rotating plate 21 moves from Figure 7 Towards Figure 8 During this process, a gap is formed between the rotating plate 21 and the cover bucket 13, so that the preforms originally at the bottom of the cover bucket 13 can flow out from the outlet of the cover bucket 13 through the above gap. When the rotating plate 21 is not swinging, the preforms on the top of the rotating plate 21 are affected by the tilt angle and flow out slowly. After the rotating plate 21 completes the angle change, the gap between the rotating plate 21 and the cover bucket 13 also synchronously limits the speed of the bottle flowing out. Through the application of the above components, the speed and flow rate of the bottle preforms flowing out can be effectively controlled to avoid the phenomenon that the internal preforms flow out at once after the equipment is tilted, causing blockage of subsequent equipment.

[0046] The buffer assembly 5 includes a fixing frame 51 fixedly connected to the top of the cover bucket 13, and an arc-shaped plate 52 is fixedly connected to one end of the fixing frame 51 away from the cover bucket 13, and a sliding track 53 is fixedly connected to the inclined surface of the cover bucket 13. Taking advantage of the angle change of the rotating plate 21, a discharge assembly 4 is arranged inside the equipment. When the angle of the rotating plate 21 changes, the rotating plate 21 will squeeze the air pressure shrink tube 1 42, so that the gas of the five air pressure shrink tubes 1 42 is transmitted to the inside of the air pressure box 1 41 and the air pressure shrink tube 1 42, and finally enters the inside of the air pressure shrink tube 2 45. As the gas inside the air pressure shrink tube 2 45 increases, the air pressure shrink tube 2 45 will be extended, and the extended push plate 46 will drive the push plate 46 to move outward, and the outward push plate 46 will contact with multiple bottle blanks. Through the application of the above-mentioned components, it is avoided that part of the bottle blanks are inside the cover bucket 13, causing the material to be stuck inside the cover bucket 13.

[0047] A U-shaped slide 54 is slidably connected to the inner wall of the sliding track 53 , a plurality of fixing rods 55 are fixedly connected to the inner wall of the U-shaped slide 54 , and a square rotating plate 56 is rotatably connected to the other ends of the plurality of fixing rods 55 .

[0048] A spring 57 is fixedly connected to the side wall of the U-shaped slide 54. The end of the spring 57 away from the U-shaped slide 54 is fixedly connected to the end of the sliding track 53 away from the fixed frame 51. By utilizing the above-mentioned characteristic that the cover bucket 13 generates an inclined angle, a buffer component 5 is arranged inside the device. When the cover bucket 13 is tilted, as the center of gravity angle of the U-shaped slide 54 changes, it presents as follows Figure 10 At this time, the U-shaped slide 54 will slide outward along the inner wall of the sliding track 53, and the U-shaped slide 54 will drive the fixing rod 55 and the square rotating plate 56 to slide outward synchronously. When the square rotating plate 56 is no longer in contact with the inclined surface of the cover bucket 13, the square rotating plate 56 will swing downward with the connection point as the center, so that the square rotating plate 56 is moved from Figure 10 The state Z is changed to the state Y, and at this time, the preforms flowing out of the cover bucket 13 will first flow out along the arc surface of the arc plate 52 and contact the side wall of the square rotating plate 56, and the square rotating plate 56 will absorb the excess power of the preforms flowing out, so that the preforms fall downward through the gap between the arc plate 52 and the square rotating plate 56. Through the application of the above components, it is avoided that the initial speed of the cover bucket 13 flowing out of the cover bucket 13 is too fast, resulting in the collision of the preforms of the plastic products after falling, resulting in the dents on the outer wall of the preforms, affecting the subsequent use.

[0049] The method for using the cover bucket structure of the preform tipping machine includes the following steps:

[0050] S1: Putting in the preform: Before use, the mounting bracket 1 is mounted at the desired position, and when the external conveyor belt conveys the preform to the inside of the cover bucket 13, the preform falls from top to bottom in the cover bucket 13;

[0051] S2: Protecting the preforms: When the falling preforms come into contact with the top of the rotating square plate 33, the weight of the preforms will force the rotating square plate 33 to rotate downward around the torsion spring 1 34, and part of the preforms will fall to the bottom of the cover hopper 13, while the remaining preforms will stay on the top of the rotating plate 21.

[0052] A specific application of this embodiment is: before use, the mounting bracket 1 is mounted at a desired position, and when the external conveyor belt conveys the preform to the inside of the cover bucket 13, the preform falls from top to bottom in the cover bucket 13, and when the falling preform contacts the top of the rotating square plate 33, the weight of the preform forces the rotating square plate 33 to rotate downward with the torsion spring 1 34 as the center, presenting the following Figure 5In the middle G state, part of the preforms will fall to the bottom of the cover bucket 13, and as the material at the bottom of the cover bucket 13 increases, the preforms at the bottom of the rotating plate 21 will contact the bottom of the rotating square plate 33, thereby limiting the rotation of the rotating square plate 33, and the excess preforms will stay on the top of the rotating plate 21, presenting a Figure 5 In the middle H state, during this process, the excess bottle blanks will stay on the top of the rotating plate 21, and the rotating plate 21 provides most of the supporting force for the bottle blanks above itself. Through the application of the above components, the bottle blanks inside the cover bucket 13 are divided into two layers to avoid excessive pressure on the bottom, which will cause the bottom bottle blanks to sag.

[0053] Taking advantage of the above-mentioned feature that the preforms are divided into two layers, a rotating frame 22 and a limit plate 23 are arranged inside the device. After the filling of the cover bucket 13 is completed, the staff can turn on the power of the motor 11. At this time, the motor 11 drives the cover bucket 13 to rotate through the driving column 12, so that the device can be rotated from Figure 2 The status changes to Figure 1 As the angle of the cover 13 changes, the rotating plate 21 is affected by gravity and rotates with the rotating frame 22, so that the rotating plate 21 changes from Figure 7 Towards Figure 8 During this process, a gap is formed between the rotating plate 21 and the cover bucket 13, so that the preforms originally at the bottom of the cover bucket 13 can flow out from the outlet of the cover bucket 13 through the above gap. When the rotating plate 21 is not swinging, the preforms on the top of the rotating plate 21 are affected by the tilt angle and flow out slowly. After the rotating plate 21 completes the angle change, the gap between the rotating plate 21 and the cover bucket 13 also synchronously limits the speed of the bottle flowing out. Through the application of the above components, the speed and flow rate of the bottle preforms flowing out can be effectively controlled to avoid the phenomenon that the internal preforms flow out at once after the equipment is tilted, causing blockage of subsequent equipment.

[0054] Taking advantage of the angle change of the rotating plate 21, a discharge assembly 4 is provided inside the equipment. When the angle of the rotating plate 21 changes, the rotating plate 21 will squeeze the air pressure shrink tube 1 42, so that the gas in the five air pressure shrink tubes 42 is transmitted to the inside of the air pressure box 1 41 and the air pressure shrink tube 1 42, and finally enters the inside of the air pressure shrink tube 2 45. As the gas inside the air pressure shrink tube 2 45 increases, the air pressure shrink tube 2 45 will extend, and the extended push plate 46 will drive the push plate 46 to move outward, and the outward-moving push plate 46 will contact with multiple bottle blanks. Through the application of the above-mentioned components, it is avoided that part of the bottle blanks are inside the cover bucket 13, causing material jamming inside the cover bucket 13.

[0055] Taking advantage of the above-mentioned characteristic that the cover bucket 13 has an inclined angle, a buffer assembly 5 is provided inside the device. When the cover bucket 13 is inclined, as the center of gravity angle of the U-shaped slide 54 changes, the following is presented: Figure 10 At this time, the U-shaped slide 54 will slide outward along the inner wall of the sliding track 53, and the U-shaped slide 54 will drive the fixing rod 55 and the square rotating plate 56 to slide outward synchronously, and at this time, the spring 1 57 will be pulled and accumulate mechanical power. When the square rotating plate 56 is no longer in contact with the inclined surface of the cover bucket 13, the square rotating plate 56 will swing downward with the connection point as the center, so that the square rotating plate 56 is moved from Figure 10 The state Z is changed to the state Y, and at this time, the preforms flowing out of the cover bucket 13 will first flow out along the arc surface of the arc plate 52 and contact the side wall of the square rotating plate 56, and the square rotating plate 56 will absorb the excess power of the preforms flowing out, so that the preforms fall downward through the gap between the arc plate 52 and the square rotating plate 56. Through the application of the above components, it is avoided that the initial speed of the cover bucket 13 flowing out of the cover bucket 13 is too fast, resulting in the collision of the preforms of the plastic products after falling, resulting in the dents on the outer wall of the preforms, affecting the subsequent use.

[0056] Among them, after the equipment completes the tipping, the motor 11 will drive the cover bucket 13 to reset, and as the angle is reset, the spring 1 57 will release the mechanical power to drive the U-shaped slide 54, the fixing rod 55, and the square rotating plate 56 to reset.
