Description

Technical Field

[0001] The utility model relates to the technical field of bread production equipment, in particular to an automatic bread bag turning and conveying device. Background Art

[0002] After the bread is produced, it needs to be packaged. For factory batch automated production, in order to save costs and improve efficiency, the bread will be placed in two rows, with eight or ten in each row, and then sealed in plastic bags at intervals. The plastic bags containing the bread are then placed in hollow plastic baskets, with two bags of bread in each plastic basket, and finally packed and transported.

[0003] Before packing, the bread model needs to be checked. The bread model is usually printed on one side of the plastic bag in the length direction. Therefore, when framing, the side with the bread model printed on it needs to be placed on the edge of the plastic basket. The two bags of bread in the same plastic basket have their sides with the model printed on them facing each other.

[0004] When the bread is automatically bagged and transported, the length of the plastic bag is consistent with the conveying direction of the conveyor, resulting in a mismatch between the side with the bread model and the position of the plastic basket. Therefore, when framing the bread, the worker needs to rotate the bread 90° forward and 90° backward in a cycle, which is not only labor-intensive and inefficient, but also prone to errors. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model discloses an automatic bread bag turning and conveying device.

[0006] The utility model provides a bread automatic bag turning and conveying device, comprising:

[0007] The first conveyor is used to convey the bagged bread, wherein the length direction of the bagged bread is parallel to the conveying direction of the first conveyor;

[0008] The second conveyor is arranged vertically with respect to the first conveyor, and the head end of the second conveyor is located directly below the tail end of the first conveyor;

[0009] A third conveyor, whose head end is adjacent to the tail end of the second conveyor, and the head end of the third conveyor is located below the tail end of the second conveyor, and the height difference is greater than the width of the bagged bread;

[0010] The suction cup is installed just above the center of the third conveyor and is driven by the driving assembly to achieve lifting and rotation. The bagged bread is rotated 180° for every bag of bread.

[0011] The conveying process of bagged bread is as follows: 1. After the bread is bagged, it is conveyed by the first conveyor with the arc surface facing upwards. The length direction of the bagged bread is parallel to the conveying direction of the first conveyor and is located at the center of the first conveyor; 2. When the bagged bread is conveyed to the tail end of the first conveyor, it falls to the head end of the second conveyor under the action of gravity and is turned over with its arc surface facing downwards; since the first conveyor and the second conveyor are perpendicular, when the bagged bread falls into the second conveyor, although the length direction of the bagged bread remains unchanged, relative to the second conveyor, the length direction of the bagged bread is arranged vertically to the conveying direction of the second conveyor; 3. When the bagged bread is conveyed to the tail end of the second conveyor, it falls to the head end of the third conveyor under the action of gravity and is turned over with its arc surface facing upwards; 4. When the bagged bread is conveyed to the bottom of the suction cup, the suction cup sequentially grabs the bagged bread, rises, rotates 180°, descends, and releases the bagged bread, and rotates the bagged bread 180° every time there is a bag of bread. The utility model realizes that the length direction of the bagged bread is automatically perpendicular to the conveying direction of the second conveyor through the conversion of the first conveyor and the second conveyor, and also makes every two bags of bagged bread form a group. The bagged bread in this group are arranged with the sides printed with models facing each other. The worker can directly grab a group of bread and put it directly in the plastic basket, which not only reduces the labor intensity but also improves the framing efficiency.

[0012] If the bagged bread falls directly from the first conveyor, part of it will be on the first conveyor and part of it will be in a falling state in which it is arranged vertically; when the bagged bread falls into the second conveyor, it will fold and be concentrated on one side of the second conveyor. The positioning accuracy is low, which is not conducive to the subsequent processes. Based on this, further improvements are made in that a first flip plate with the same height as the conveyor belt is provided on the outer side of the tail end of the first conveyor; one side of the first flip plate is set as a flip side, which forms an acute angle with the length direction of the bagged bread, and its inclination angle is configured as follows: when the bagged bread slides completely onto the first flip plate, the center of gravity of the bagged bread will leave the first flip plate and fall onto the second conveyor from the flip side.

[0013] In order to improve the installation strength of the first flip plate, a further design is: a bracket is installed at the upper end of the head end of the second conveyor; a rectangular frame is set on the top of the bracket; the first flip plate is installed on the inner side of the rectangular frame; the first flip plate is in a right-angled trapezoid, and its bottom side and the waist perpendicular to the bottom side are fixedly installed on one side of the rectangular frame, and the other waist is the flip side, which is spaced apart from the other side of the rectangular frame, thereby forming a drop hole, so that the bagged bread falls from the drop hole.

[0014] If one side of the rectangular frame is located close to the first conveyor, it is easy for the bagged bread to have difficulty sliding smoothly onto the first flip plate. Therefore, the position accuracy of the rectangular frame and the first conveyor is relatively high, and the position accuracy of the rectangular frame and the first flip plate is also relatively high, resulting in high processing difficulty and assembly difficulty. Based on this, further improvements are as follows: the bracket includes two U-shaped first legs and second legs with openings facing downward and symmetrically arranged; the first leg is located close to the head end of the second conveyor; the first leg and the second leg span both sides of the second conveyor, and the first connecting rod is connected to the top of the first leg and the second leg away from the first conveyor, and the second connecting rod is connected to the middle position of the first leg and the second leg close to the first conveyor, and the second connecting rod is located below the conveyor belt of the first conveyor; the longer bottom edge of the first flip plate is fixedly connected to the first connecting rod, the waist perpendicular to the bottom edge is fixedly connected to the second leg, and the shorter bottom edge is close to the tail end of the first conveyor.

[0015] When bagged bread falls directly from the second conveyor, it is easy to fall off the third conveyor and fall to the ground. Based on this, a further improvement is that a second flip plate is provided at the head end of the third conveyor; the second flip plate spans both sides of the tail of the second conveyor and is located near the tail end of the second conveyor.

[0016] Since bagged bread is easily cut by the outer side of the second turning plate, a further improvement is that the second turning plate is provided with a flange extending downward and forming an acute angle at one end away from the second conveyor.

[0017] In order to ensure that the bagged bread can be stably moved to the second flip plate, the installation position accuracy of the second flip plate is relatively high, thereby increasing the difficulty of installing the second flip plate. Based on this, further improvements are made in that: the second flip plate is arranged in an inclined manner, with its lower end close to the second conveyor and lower than the top of the upper conveyor belt of the second conveyor, and the drop is 5±1mm; the upper end of the second flip plate is 5±1mm higher than the top of the upper conveyor belt of the second conveyor. With this arrangement, the bagged bread can be stably moved to the second flip plate under the friction of the second conveyor; and the top of the second flip plate is higher than the second conveyor, so that the bagged bread will not fall from the second flip plate in advance under the action of gravity, thereby improving the position stability of the bagged bread falling into the third conveyor, and also improving the shape stability of the bagged bread when falling into the third conveyor.

[0018] The specific installation structure of the suction cup is as follows: a fixed frame is installed at the upper end of the third conveyor; a lifting cylinder, a rotating cylinder and a mounting plate are installed on the fixed frame; the mounting plate is arranged horizontally, and the suction cup is arranged in two rows in the width direction of the third conveyor and fixed at the lower end of the mounting plate; the driving end of the rotating cylinder is fixedly connected to the mounting plate, and is used to drive the mounting plate to rotate 180°; the piston rod of the lifting cylinder is vertically downward and is fixedly connected to the rotating cylinder, and is used to drive the rotating cylinder to lift and lower.

[0019] In order to ensure that the mounting plate is lightened and the load on the lifting cylinder and the rotating cylinder is reduced while ensuring the strength of the mounting plate, a further design is as follows: two symmetrically arranged U-shaped grooves are provided on the mounting plate, and the groove walls thereof extend in the width direction of the third conveyor; the suction cup is arranged on the groove wall of the U-shaped groove; and the width of the U-shaped groove increases gradually from the bottom to the end.

[0027] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0028] like Figure 1 As shown, the utility model discloses an automatic bread bag turning and conveying device, comprising a first conveyor 1, a second conveyor 2 and a third conveyor 3.

[0029] The bagged bread is conveyed from the head end of the first conveyor 1 to the tail end of the first conveyor 1, wherein the bread in the plastic bag is arranged in two rows, with five in each row. The length direction of the bagged bread is parallel to the conveying direction of the first conveyor 1, and the bagged bread is located at the center of the first conveyor 1.

[0030] The second conveyor 2 is L-shaped, and is composed of a starting section conveyor, a 90-degree corner conveyor, and a final section conveyor connected in sequence. The starting section conveyor is perpendicular to the first conveyor 1, and the tail end of the first conveyor 1 is against the side of the starting section conveyor. The head end of the starting section conveyor is located below the tail end of the first conveyor 1. A bracket 6 is installed at the upper end of the head end of the starting section conveyor, and a first flip plate 5 is installed on the bracket 6. The specific structure is as follows: Figure 2 As shown, the bracket 6 includes two U-shaped, downwardly opened, symmetrically arranged first legs 61 and second legs 62; the first legs 61 and second legs 62 span across both sides of the starting section conveyor, and the first legs 61 and second legs 62 are connected to the top of the end away from the first conveyor 1 with a first connecting rod 63, and the middle position of the first legs 61 and second legs 62 close to the first conveyor 1 is connected to the second connecting rod 64, and the second connecting rod 64 is located below the conveyor belt of the first conveyor 1; the first flip plate 5 is a right-angled trapezoid, and its longer bottom is fixedly connected to the first connecting rod 63, and the waist perpendicular to the bottom is fixedly connected to the second leg 62, and the shorter bottom is close to the tail end of the first conveyor 1. The first flip plate 5 is arranged horizontally, and its top is flush with the top of the conveyor belt on the upper part of the first conveyor 1. The other waist is set as the flip side 51, and a gap is set with the other side of the rectangular frame, so as to form a drop hole, so that the bagged bread falls from the flip side 51 into the drop hole and finally falls on the starting section conveyor. The tilt angle of the flip side 51 is configured such that when the bagged bread completely slides onto the first flip plate 5 , the center of gravity of the bagged bread will be separated from the first flip plate 5 and fall from the flip side 51 onto the second conveyor 2 .

[0031] The third conveyor 3 is in line with the last section conveyor, and the head end of the third conveyor 3 is located below the tail end of the last section conveyor. A support frame is installed at the head end of the third conveyor 3, and a cylindrical support rod is fixed to the top of the support frame by welding. The support rod is perpendicular to the conveying direction of the third conveyor 3. A second flip plate 7 is welded to the support rod. The second flip plate 7 spans across both sides of the tail of the second conveyor 2 and is located near the tail end of the second conveyor 2. Its specific structure is as follows: Figure 4 and Figure 5As shown, the second flip plate 7 is arranged in an inclined manner, with an angle of 15° with the horizontal plane. The lower end of the second flip plate 7 is close to the second conveyor 2, and a connecting plate extends vertically downward from the lower end, which is fixed to the side of the support rod close to the second conveyor 2 by welding. A guide edge 72 extends vertically downward from the upper end of the second flip plate 7, and a flange 71 that forms an acute angle with the second flip plate 7 extends downward from the guide edge 72. The lower end of the second flip plate 7 is lower than the top of the upper conveyor belt of the second conveyor 2, and the height difference is 5±1mm; the upper end of the second flip plate 7 is higher than the top of the upper conveyor belt of the second conveyor 2 by 5±1mm. With such a configuration, the bagged bread can be stably moved to the second flip plate 7 under the friction force of the second conveyor 2; and the top of the second flip plate 7 is higher than the second conveyor 2, so that the bagged bread will not fall from the second flip plate 7 in advance under the action of gravity, thereby improving the position stability of the bagged bread falling into the third conveyor 3, and also improving the shape stability of the bagged bread when falling into the third conveyor 3. The guide edge 72 can make the bagged bread fall obliquely downward, away from the head end of the third conveyor 3, and can stably fall on the third conveyor 3. The flange 71 can prevent the blade from cutting the plastic bag.

[0032] The upper end of the third conveyor 3 is equipped with a fixed frame 8; Figure 3 As shown, the fixed frame 8 is equipped with a lifting cylinder 81, a rotating cylinder 82, a mounting plate 83 and a suction cup 4; the mounting plate 83 is arranged horizontally, and the suction cup 4 is arranged in two rows spaced apart in the width direction of the third conveyor 3 and fixed to the lower end of the mounting plate 83; the driving end of the rotating cylinder 82 is fixedly connected to the mounting plate 83, and is used to drive the mounting plate 83 to rotate 180°; the piston rod of the lifting cylinder 81 is vertically downward and is fixedly connected to the rotating cylinder 82, and is used to drive the rotating cylinder 82 to rise and fall. The above arrangement is used to rotate the bagged bread 180° for each bag of bread.

[0033] The mounting plate 83 is provided with two symmetrically arranged U-shaped grooves 84, whose groove walls extend in the width direction of the third conveyor 3; the suction cup 4 is arranged on the groove wall of the U-shaped groove 84; the U-shaped groove 84 is trapezoidal, and its width increases from the bottom to the end. The setting of the U-shaped groove 84 is not only used to reduce the weight of the mounting plate 83 and reduce the load of the lifting cylinder 81 and the rotating cylinder 82, but also its trapezoidal structure design can ensure that the mounting plate 83 maintains sufficient strength.

[0034] The conveying process of bagged bread is as follows: 1. After the bread is bagged, it is conveyed through the first conveyor 1 with the arc surface facing upwards. The length direction of the bagged bread is parallel to the conveying direction of the first conveyor 1 and is located at the center of the first conveyor 1; 2. When the bagged bread is conveyed to the tail end of the first conveyor 1, it moves to the first flip plate 5 under the action of friction; when the bagged bread is completely moved to the first flip plate 5, its center of gravity is separated from the first flip plate 5, and it falls from the flip side 71 to the head end of the starting section conveyor under the action of gravity, and is turned over with its arc surface facing downwards; since the first conveyor 1 and the starting section conveyor are perpendicular, when When the bagged bread falls into the starting section conveyor, although the length direction of the bagged bread remains unchanged, relative to the starting section conveyor, the length direction of the bagged bread is arranged perpendicular to the conveying direction of the starting section conveyor; 3. When the bagged bread is conveyed to the tail end of the last section conveyor, it moves to the second flip plate under the action of friction, and falls to the head end of the third conveyor 3 under the action of gravity to achieve flipping, with its arc surface facing upward; 4. When the bagged bread is conveyed to the bottom of the suction cup 4, the suction cup 4 operates in sequence to grab the bagged bread, rise, rotate 180°, fall, and release the bagged bread, and rotates the bagged bread 180° every time a bag of bread is separated. The utility model realizes that the length direction of the bagged bread is automatically perpendicular to the conveying direction of the second conveyor 2 through the conversion of the first conveyor 1 and the second conveyor 2, and also makes every two bags of bagged bread form a group, and the sides of the bagged bread in this group with the model printed on them are arranged back to back. Workers can directly grab a group of bread and place it directly in the plastic basket, which not only reduces the labor intensity but also improves the framing efficiency.

[0035] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
