Description

Technical Field

[0001] The utility model relates to the technical field of box turning mechanisms, in particular to a box turning machine. Background Art

[0002] When the finished boxes are unloaded from the assembly line to the box, they need to be flipped from a flat state to a vertical state, and arranged into rows. After placing enough boxes for a row, they can be packed. Traditionally, this process requires manual operation, at least one person is required to perform the flipping and placing actions, and another person is required to sort, place and pack. This process is cumbersome and labor-intensive, especially for production lines with high output, one person may be required to assist in placement. Each line requires 2-3 people, which is costly, and the consistency of manually operated items cannot be guaranteed. At present, there are some flipping devices on the market, some of which use manipulators to flip, and the equipment cost is high; there are simple flipping devices, but they cannot meet the flipping and placement of boxes of different sizes and relatively high heights, or the size of the whole machine is too large and occupies a large production space. Therefore, in view of this situation, how to efficiently perform flipping and placement operations on items of different sizes and specifications, while having a smaller equipment cost, is a problem that technicians in this field need to consider.

[0035] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0036] like Figure 1-6 As shown, a box turning machine includes a feeding assembly 2, a turning assembly 3 and a storage bin 4 which are sequentially arranged on a machine table 1. In this embodiment, the feeding assembly 2, the turning assembly 3 and the storage bin 4 are sequentially arranged in the direction of the article transmission; in other embodiments, the above mechanisms can be arranged in other ways according to actual needs.

[0037] like Figure 4 As shown, the loading assembly 2 can convey articles in a preset direction. In this embodiment, the loading assembly 2 includes a conveyor belt 21 and a first bracket 22. The conveyor belt 21 is arranged on the first bracket 22 and driven to rotate by a fourth driving device 23. The first bracket 22 is connected to the machine 1, which can be connected through the bar holes and bolts arranged on the first bracket 22 or the machine 1, or by arranging a lifting cylinder and a rotating cylinder between the first bracket 22 and the machine 1, or by adopting an adjustable structure to connect, so that the height and angle of the first bracket 22 on the machine 1 can be adjusted and fixed, and then the downward end of the conveyor belt 21 in the conveying direction can be adjusted to extend into the flip assembly 3. The height of the conveyor belt 21 and its pitch angle in the conveying direction can also be adjusted. When the article is conveyed to the flip assembly 3, its end can accurately contact with the bearing part 3111 and trigger the sensor on the bearing part 3111, and the flip assembly 3 performs the flipping action. The end face of the conveyor belt 21 that carries and conveys the article is lower than the upper end face of the baffle 5 to ensure that the baffle 5 effectively guides and limits the article on the conveyor belt 21. In other embodiments, the conveyor belt 21 may also be a conveyor roller or a conveyor wheel or other mechanism capable of conveying articles. In addition, the end of the baffle plate 5 at the upper end of the conveying direction of the loading assembly 2 may be set as an opening bent toward both ends, that is, when the article is conveyed from the previous process to the baffle plate position, if the conveying direction or posture of the article is slightly deflected, it can be automatically adjusted by sliding against the opening of the baffle plate; the setting of the opening can assist the article in automatically adjusting the posture of entering the baffle plate 5, so as to facilitate the subsequent flipping and storage actions.

[0038] like Figure 5As shown, the flip assembly 3 flips the articles conveyed by the loading assembly 2. The flip assembly 3 includes a flip wheel 31, and one or more flip blades 311 are arranged on the circumference of the flip wheel 31. The flip blade 311 includes a bearing portion 3111 and a forward push portion 3112. The bearing portion 3111 is close to the rear end of the travel path of the flip blade 311, and the forward push portion 3112 is close to the front end of the travel path of the flip blade 311. The bearing portion 3111 receives the articles conveyed by the loading assembly 2 and rotates with the flip wheel 31, while the forward push portion 3112 pushes the articles at the loading station 4a to move at least a distance of the height of the articles. The flip assembly 3 also includes a rotating shaft 32 connected to the flip wheel 31, and the rotating shaft 32 is connected to a first driving device 33; the first driving device 33 drives the flip wheel 31 to rotate through the rotating shaft 32.

[0039] Two or more turning wheels 31 are provided, and the distance between two adjacent turning wheels 31 is smaller than the width of the object.

[0040] In this embodiment, the rotating shaft 32 can be connected to the first driving device 33 through a reducer, and the first driving device 33 can be a device that can drive rotation, such as a servo motor. Two flip wheels 31 are provided, and the projections of the two flip wheels 31 along the axial direction of the rotating shaft 32 completely overlap to ensure the consistency of the two flip wheels 31, thereby ensuring stability when receiving and flipping objects; the two flip wheels 31 are arranged in parallel at the downstream end of the transmission direction of the feeding assembly 2. In other embodiments, other numbers of flip wheels 31 can be provided so that the bearing part 3111 can stably support objects when flipping. One end of the flip blade 311 is rotatably connected to the flip wheel 31, and the other end is provided with an arc-shaped long strip hole 3113, and a fastening device such as a bolt is connected to the flip blade 311 through the long strip hole 3113. The flip blade 311 is rotated and adjusted relative to the flip wheel 31, and the position of the flip blade 311 is adjusted by fixing the position of the bolt at the long strip hole 3113; of course, in the adjustment of the flip blade 311, the adjustment of all flip blades 311 is synchronized. A corresponding sensor (not shown) can be provided at the position of the bearing portion 3111 to trigger the operation of the first driving device 33. In this embodiment, four flip blades 311 are provided, and the first driving device 33 drives the flip wheel 31 to rotate 90° each time. In other embodiments, one, two, three or other numbers of flip blades 311 can also be provided, and the corresponding flip wheel 31 rotates at an angle of 360°, 180° or 120°, etc., and so on. It should be noted that if one flip blade 311 is provided, the 360° rotation of the flip wheel 31 needs to be completed before the next item is transferred to the flip assembly 3, otherwise it will interfere with the item.

[0041] It should also be noted that during the rotation of the flip wheel 31, the conveyor belt 21 is also continuously driven. The bearing portion 3111 is a plane, and each time it stops after rotation, it is perpendicular to the plane where the upper end surface of the conveyor belt 21 is located, so that when the object is conveyed to the bearing portion 3111, it can stably contact the bearing portion 3111; and the bearing portion 3111 is at a certain distance from the end of the downward end of the conveying stroke of the conveyor belt 21, so that when the end of the object contacts the bearing portion 3111, at least part of its area has completely separated from the conveyor belt 21, so as to avoid the conveyor belt 21 from interfering with the flipping action of the flip assembly 3. The forward pusher 3112 is convex relative to the flip blade 311, that is, on the path of the forward pusher 3112 rotating with the flip wheel 31, the distance between the connection between the forward pusher 3112 and the bearing part 3111 and the rotation axis is greater than the distance between other parts of the forward pusher 3112 and the axis of the rotating shaft 32, and the farther away from the connection with the bearing part 3111 on the forward pusher 3112, the smaller the distance between the forward pusher 3112 and the rotation axis of the rotating shaft 32. This arrangement allows the forward pusher 3112 to slide and press smoothly in the process of pushing the items on the platform 41, which can avoid scratches or punctures on the items, and can also prevent the items on the platform 41 away from the flip assembly 3 from falling over.

[0042] like Figure 2-3 As shown, the storage bin 4 is connected to the side of the flip assembly 3 away from the loading assembly 2, stores the flipped articles, and is provided with a loading station 4a. The storage bin 4 includes a platform 41 for carrying articles, and one end of the platform 41 close to the flip assembly 3 extends toward the flip assembly 3 to the loading station 4a, and a height-adjustable brush strip 42 is provided above the platform 41; when the flipped articles are placed on the platform 41, the upper end of the articles are in contact with the bristles at the lower end of the brush strip 42.

[0043] like Figure 6 As shown, the storage bin 4 also includes a material dividing assembly 43 arranged below the carrier 41, and the material dividing assembly 43 includes a fixedly arranged second driving device 431, a third driving device 432 connected to the second driving device 431, and the third driving device 432 is connected to a push plate 433; wherein, the driving movement direction of the second driving device 431 is the same as the movement direction of the object on the carrier 41; the third driving device 432 can drive the push plate 433 to move in the vertical direction.

[0044] A full material sensor (not shown) is disposed at one end of the carrier 41 away from the flip assembly 3 .

[0045] In this embodiment, the carrier 41 extends to the loading station 4a, and its extension part can be between the two flip wheels 31 or on both sides of the flip wheel 31. When the bearing part 3111 receives the article and rotates to the loading station 4a with the flip wheel 31, the end of the article is pushed against the extension part of the carrier 41, that is, the article is flipped and placed on the carrier 41 of the loading station 4a. When the flip wheel 31 rotates again, the forward push part 3112 contacts and pushes the article to move a certain distance on the carrier 41 to make way for the next article. In actual operation, when the forward push part 3112 pushes the article to move on the carrier 41, the contact position between the forward push part 3112 and the article changes, resulting in uneven force on the article, which is easy to fall over. Therefore, a brush strip 42 is provided above the carrier 41. When an object is pushed forward, its upper end surface contacts and connects with the brush at the lower end of the brush strip 42, which can support the object and prevent it from falling over without hindering the movement of the object.

[0046] It should be noted that when there are two or more objects on the carrier 41, the two objects collide with each other, and when the front pusher 3112 pushes the objects, the force on the objects is relatively stable and not easy to cause falling. Therefore, the length of the brush is at least greater than the width of one object to ensure the stability of the objects placed on the carrier 41. The height and position of the brush should be adjustable to suit objects of different sizes.

[0047] The full material sensor can be a photoelectric sensor or a contact sensor, and its position on the carrier 41 can be adjusted. Of course, it is not necessarily located directly above the carrier 41. Figure 1 As shown in the figure, the side of the carrier 41 away from the flipping assembly is connected to a workbench, so that more items can be arranged and placed each time; at this time, the full-fill sensor is set above the workbench. When the flipped items are placed one by one on the carrier 41 and pushed forward to the full-fill sensor for induction, it means that the items on the carrier 41 have reached the preset maximum number, and the loading assembly 2 and flipping assembly 3 should stop working. At this time, the operator or other mechanical devices will transfer the items placed on the carrier 41 to the packaging box or other processes.

[0048] In this embodiment, when the height of the object is too large and exceeds the maximum adjustable working height of the flip blade 311, the material dividing assembly 43 can be activated. Each time the flipping action is performed, the third driving device 432 pushes the push plate 433 to move upward when the material is placed on the carrier 41, and then the second driving device 431 drives the third driving device 432 and the push plate 433 to move, so that the push plate 433 pushes the object on the carrier 41 to move a certain distance away from the flip assembly 3; then the second driving device 431 and the third driving device 432 are reset in sequence. Through the operation of the material dividing assembly 43, the end of the carrier 41 close to the flip assembly 3 has a distance at least greater than the height of an object, so as to place the next flipped object.

[0049] The second driving device 431 and the third driving device 432 may be cylinders or driving modules or other devices capable of driving movement.

[0050] Baffles 5 are also provided on both sides of the feeding assembly 2, and one end of the baffles 5 on both sides extends to both sides of the flip assembly 3 and the storage bin 4, and the baffles 5 are at least partially higher than the feeding assembly 2 and the carrier 41. In this embodiment, the baffles 5 are set on the machine 1 through the second bracket 51. Among the baffles 5 on both sides, the position of at least one side of the baffles 5 should be adjustable. Specifically, the outer side of the baffle 5 is connected to the second bracket 51 through a guide rod 52 or other supporting device, and the distance between the baffles 5 on both sides is adjusted by adjusting the position of the guide rod 52 on the second bracket 51 to accommodate items of different widths.

[0051] In addition, it should be noted that the box turning machine also includes other mechanisms such as an electrical box and a control device. Figure 1 As shown, a mechanism for completing the article transfer can also be provided at the upper end of the feeding assembly 2, which can transfer the articles from the previous process to the conveyor belt 21 of the feeding assembly 2; an operating table can also be provided at the lower end of the storage bin 4 to assist in sorting or to extend the loading platform. The above are all prior arts and will not be described here in detail.

[0052] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
