Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging machinery technology, and in particular to a conveying device. Background Technology

[0002] Some existing blister pack machines on the market operate intermittently. The trays on the blister pack transfer conveyor are arranged in a 2x3 matrix pattern, with close spacing between rows and columns. However, subsequent processes require merging into a single-column conveyor (i.e., the conveyor mechanism has only a single tray in its width direction). This presents the challenge of how to achieve a straight-line spacing between the three trays while simultaneously creating a rapid 90° spacing to prevent the two rows of trays from colliding with the following trays. Existing merging conveyor devices mostly achieve this through curved turns, which is structurally complex, costly, and causes the trays to rotate, resulting in a change in their orientation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a conveying device with a simple structure, which can facilitate the merging and conveying of materials and increase the distance between two adjacent materials after merging.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A conveying device includes a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism connected sequentially. The conveying direction of the second conveying mechanism forms a 45° angle with the conveying direction of the first conveying mechanism, and the conveying direction of the third conveying mechanism forms a 45° angle with the conveying direction of the second conveying mechanism. The conveying direction of the third conveying mechanism is perpendicular to the conveying direction of the first conveying mechanism. Both the second and third conveying mechanisms include a drive roller, a transition roller, a first reversing member, a first tensioning roller, a second reversing member, and a conveyor belt. The transition roller is arranged parallel to the drive roller. The first reversing member and the second reversing member are arranged parallel to each other and form a 45° angle with the drive roller. The first tensioning roller is arranged perpendicular to the drive roller. The conveyor belt is sequentially wound around the drive roller, the transition roller, the first reversing member, the first tensioning roller, and the second reversing member. The first reversing member of the second conveying mechanism is located close to the first conveying mechanism, and the transition roller of the second conveying mechanism is located close to the first reversing member of the third conveying mechanism.

[0005] As a further improvement to the above technical solution: a second tensioning roller is also provided between the second reversing component and the driving roller.

[0006] As a further improvement to the above technical solution: the conveying device also includes a housing, on which a strip-shaped hole is provided. The two ends of the tensioning roller shafts of the first tensioning roller and the second tensioning roller are respectively disposed in one of the strip-shaped holes. An adjusting element for adjusting the position of the tensioning roller shaft in the strip-shaped hole is provided on one side of the strip-shaped hole.

[0007] As a further improvement to the above technical solution: the first reversing component is provided with multiple contact surfaces that contact the conveyor belt, and a transition fillet is provided between two adjacent contact surfaces.

[0008] As a further improvement to the above technical solution: the contact surface is a plane.

[0009] As a further improvement to the above technical solution: the first commutator and the second commutator are hollow square tubes, U-shaped grooves, or commutator bars with an L-shaped cross-section.

[0010] As a further improvement to the above technical solution: the transition roller includes an installation strip and multiple segments spaced apart along the length of the installation strip, a support shaft is inserted through the segment, bearings are provided between the two ends of the segment and the support shaft, and the installation strip is provided with support seats at both ends of the support shaft.

[0011] As a further improvement to the above technical solution: the support base is detachably connected to the mounting strip, and the support shaft is detachably connected to the support base.

[0012] As a further improvement to the above technical solution: the cross-section of the mounting strip is an L-shaped structure.

[0013] As a further improvement to the above technical solution: the third conveying mechanism is provided with a first baffle and a second baffle on both sides respectively. The first baffle is arranged along the conveying direction of the third conveying mechanism and extends towards the second conveying mechanism. Along the conveying direction of the third conveying mechanism, the distance between the second baffle and the third conveying mechanism gradually decreases.

[0014] Compared with the prior art, the advantages of this utility model are: The conveying device disclosed in this utility model uses a second conveying mechanism and a third conveying mechanism to form a 45° angle between the conveyor belt and the first conveying mechanism via a drive roller, a transition roller, a first reversing component, a second reversing component, and a first tensioning roller. The first reversing component of the second conveying mechanism is positioned close to the first conveying mechanism, and the transition roller of the second conveying mechanism is positioned close to the first reversing component of the third conveying mechanism (i.e., the angle of the second conveying mechanism aligns with the first conveying mechanism, and the angle of the third conveying mechanism aligns with the second conveying mechanism). When material is transferred from the first conveying mechanism to the second conveying mechanism, each column of material arrives at the second conveying mechanism sequentially and completes the first reversing conveying. When material is further transferred from the second conveying mechanism to the third conveying mechanism, adjacent rows of material are arranged along the conveying direction of the third conveying mechanism, thus arriving at the third conveying mechanism sequentially. The third conveying mechanism then separates the rows, completing the second reversing conveying, thus achieving confluence conveying. Compared to existing arc-shaped turning conveying mechanisms, the second and third conveying mechanisms in this utility model convey material in a fixed direction, preventing material rotation and ensuring consistent orientation. Furthermore, the structure is simpler and the cost is lower.

[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Figures 1 to 6This illustration shows an embodiment of the conveying device of the present invention. The conveying device of this embodiment includes a first conveying mechanism 1, a second conveying mechanism 2, and a third conveying mechanism 3 connected sequentially. The conveying direction of the second conveying mechanism 2 forms a 45° angle with the conveying direction of the first conveying mechanism 1, and the conveying direction of the third conveying mechanism 3 forms a 45° angle with the conveying direction of the second conveying mechanism 2. The conveying direction of the third conveying mechanism 3 is perpendicular to the conveying direction of the first conveying mechanism 1. Both the second conveying mechanism 2 and the third conveying mechanism 3 include a drive roller 21 (i.e., capable of rotation), a transition roller 22, and a first reversing element 2. 3. A first tension roller 24, a second reversing element 25, and a conveyor belt 26 are included. A transition roller 22 is arranged parallel to the drive roller 21. The first reversing element 23 and the second reversing element 25 are arranged parallel to each other and form a 45° angle with the drive roller 21. The first tension roller 24 is arranged perpendicular to the drive roller 21. The conveyor belt 26 is sequentially wound around the drive roller 21, the transition roller 22, the first reversing element 23, the first tension roller 24, and the second reversing element 25. The first reversing element 23 of the second conveying mechanism 2 is located close to the first conveying mechanism 1, and the transition roller 22 of the second conveying mechanism 2 is located close to the first reversing element 23 of the third conveying mechanism 3. Preferably, the conveyor belt 26 of the second conveying mechanism 2 and the third conveying mechanism 3 is a knife-edge belt. Knife-edge belts are thin and highly flexible, suitable for conveying small-sized, thin materials. The first conveying mechanism 1 can be a common conveyor belt, plate chain, etc.

[0027] In this embodiment of the conveying device, the second conveying mechanism 2 and the third conveying mechanism 3 form a 45° angle on the conveyor belt 26 through the drive roller 21, transition roller 22, first reversing member 23, second reversing member 25, and first tensioning roller 24. The first reversing member 23 of the second conveying mechanism 2 is positioned close to the first conveying mechanism 1, and the transition roller 22 of the second conveying mechanism 2 is positioned close to the first reversing member 23 of the third conveying mechanism 3 (i.e., the angle of the second conveying mechanism 2 aligns with the first conveying mechanism 1, and the angle of the third conveying mechanism 3 aligns with the second conveying mechanism 2). See details [link to documentation]. Figure 1 and Figure 6When the material (in this embodiment, tray 5) is transferred from the first conveying mechanism 1 to the second conveying mechanism 2 (specifically, the conveyor belt 26 of the second conveying mechanism 2), each column of material arrives at the second conveying mechanism 2 sequentially and completes the first reversing conveying. When the material is further transferred from the second conveying mechanism 2 to the third conveying mechanism 3 (specifically, the conveyor belt 26 of the third conveying mechanism 3), adjacent rows of material are arranged along the conveying direction of the third conveying mechanism 3, thus arriving at the third conveying mechanism 3 sequentially. Then, the third conveying mechanism 3 separates the materials, completing the second reversing conveying, which can achieve confluence conveying. Compared with the existing arc-shaped turning conveying mechanism, the second conveying mechanism 2 and the third conveying mechanism 3 in this utility model convey materials in a fixed direction, so the material does not rotate, the orientation does not change, and the structure is simpler and the cost is lower.

[0028] See details Figure 2 and Figure 3 In this embodiment, a second tension roller 27 is also provided between the second reversing component 25 and the drive roller 21. Since the conveyor belt 26 reverses direction many times, the second tension roller 27 cooperates with the first tension roller 24 to keep the conveyor belt 26 in a taut state, thereby achieving stable operation. The structure is simple and reliable.

[0029] See details Figure 2 In this embodiment, the conveying device further includes a housing 4, which has a strip-shaped hole 41. The two ends of the tension roller shafts 28 of the first tension roller 24 and the second tension roller 27 are respectively disposed in the strip-shaped hole 41. One side of the strip-shaped hole 41 is provided with an adjusting member 42 for adjusting the position of the tension roller shafts 28 in the strip-shaped hole 41. The adjusting member 42 can be, for example, a screw, a push rod, etc., which can push the tension roller shafts 28 to move in the strip-shaped hole 41, thereby realizing tension adjustment and preventing the conveyor belt 26 from running off-center.

[0030] Furthermore, in this embodiment, the first reversing member 23 is provided with multiple contact surfaces 231 that contact the conveyor belt 26, and a transition fillet 232 is provided between two adjacent contact surfaces 231. A portion of the bottom of the tray 5 is uneven. The transition fillet 232 between two adjacent contact surfaces 231 of the first reversing member 23 allows for a narrower gap at the transition points between the first conveying mechanism 1 and the second conveying mechanism 2, and between the second conveying mechanism 2 and the third conveying mechanism 3. This helps prevent the tray 5 from overturning or becoming clogged, achieving smooth transition conveying. The structure is simple and effective.

[0031] In a preferred embodiment, the contact surface 231 is a plane, which can increase the contact area between the first reversing member 23 and the conveyor belt 26, and help prevent the conveyor belt 26 from slipping along the length direction of the first reversing member 23.

[0032] Furthermore, in this embodiment, the first reversing member 23 and the second reversing member 25 are hollow square tubes, which facilitate the reversing of the conveyor belt 26, and are themselves high in strength and light in weight. The cross-section can be either square or rectangular.

[0033] Of course, in other embodiments, the first reversing member 23 and the second reversing member 25 may also be a U-shaped groove (equivalent to removing the side of the square tube that is not in contact with the conveyor belt 26), or a reversing bar with an L-shaped cross-section (equivalent to removing the side of the square tube that is not in contact with the conveyor belt 26 and further reducing one contact surface).

[0034] See details Figure 4 and Figure 5 In this embodiment, the transition roller 22 includes a mounting strip 221 and multiple segments 222 spaced apart along the length of the mounting strip 221. Support shafts 223 are threaded through the segments 222, and bearings 224 are provided between the two ends of each segment 222 and the support shafts 223. Support seats 225 are provided at both ends of the mounting strip 221 and the support shafts 223. For materials such as trays 5, the conveyor belt 26 is relatively wide, and the radius of the transition roller 22 is relatively small. Using multiple segments 222 allows the high tension of the conveyor belt 26 to be evenly distributed across multiple mounting seats 225, reducing the load on the small-sized support shafts 223 and bearings 224, which helps improve reliability and extend service life.

[0035] Furthermore, in this embodiment, the support base 225 is detachably connected to the mounting strip 221, and the support shaft 223 is detachably connected to the support base 225, for example, by means of bolts, screws, etc., to facilitate the inspection and maintenance of the transition roller 22.

[0036] As a preferred embodiment, the cross-section of the mounting strip 221 is L-shaped, which helps to improve the strength of the mounting strip 221 itself. At the same time, the horizontal part of the mounting strip 221 can be fixedly connected to the housing 4, while the vertical part is used to install the support base 225. They do not interfere with each other, and the structure is simple and effective.

[0037] See details Figure 1 In this embodiment, a first baffle 31 and a second baffle 32 are respectively provided on both sides of the third conveying mechanism 3. The first baffle 31 is arranged along the conveying direction of the third conveying mechanism 3 and extends towards the second conveying mechanism 2. Along the conveying direction of the third conveying mechanism 3, the distance between the second baffle 32 and the third conveying mechanism 3 gradually decreases. The first baffle 31 can guide the tray 5 on the second conveying mechanism 2 to be smoothly transferred to the third conveying mechanism 3, and the second baffle 32 can cooperate with the first baffle 31 to position the tray 5, so that the tray 5 is accurately positioned on the third conveying mechanism 3.

[0038] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
