Description

Technical Field

[0001] The utility model relates to the technical field of palletizing, and particularly relates to a palletizing device. Background Art

[0002] After the aluminum sheets are produced and formed, palletizing operation is crucial to ensure the convenience of storage and transportation. Currently, as the mainstream tool, the palletizer positions the aluminum sheets through the built-in blanking structure to achieve the stacking of aluminum sheets. At the same time, the receiving device uses its receiving tray to carry the aluminum sheets sliding down from the blanking port of the blanking structure, and then the aluminum sheets are uniformly packed and transported after accumulating into a stack. However, for oval sheets, due to the different lengths of the major axis and the minor axis, the traditional blanking structure has insufficient circumferential limiting ability, resulting in poor palletizing neatness of oval sheets.

[0003] To improve the palletizing neatness of oval sheets, we have actively explored and developed various improvement schemes in the early stage, as shown in the patent applications with publication numbers CN110615288A and CN111960164A. However, in practical applications, these improvement schemes still face the following technical problems: on the one hand, the structural design is relatively complex, increasing the manufacturing difficulty and cost, and is not user-friendly for users with strict cost control requirements; on the other hand, although the improvement of the blanking structure has improved the palletizing neatness of oval sheets to a certain extent, there are problems that oval sheets are prone to getting stuck in the blanking structure and aluminum sheets are easily scratched by the limiting rods, which has an adverse impact on production efficiency and product quality.

[0027] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention, rather than for limiting the protection scope of the present invention.

[0028] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0029] As Figures 1 to 5 shown, a palletizing device includes a frame 1, a top plate 2, multiple first limiting rods 301, and multiple second limiting rods 401. The top plate 2 is installed on the top of the frame 1. A blanking port 201 is provided on the top plate 2. Multiple first limiting rods 301 are respectively vertically arranged at the left front and right front of the blanking port 201. Multiple second limiting rods 401 are respectively vertically arranged at the left rear and right rear of the blanking port 201. The lower segments of the multiple second limiting rods 401 are vertical, and the upper segments of the multiple second limiting rods 401 are respectively inclined outward from bottom to top.

[0030] With the above technical solution, a plurality of first limiting rods 301 and a plurality of second limiting rods 401 form a limiting structure at the blanking port 201, which can position the sheets to be palletized, so as to promote neater palletizing of the sheets. In the above technical solution, by setting the upper section of the second limiting rod 401 to be inclined outward from bottom to top, the upper section of the second limiting rod 401 can play a role in guiding the sheets to be palletized to slide down. Especially when the sheets to be palletized are inclined, the edge of the higher side of the sheets to be palletized is supported on the upper section of the second limiting rod 401. Since the upper section of the second limiting rod 401 is inclined, the sheets to be palletized can smoothly slide down along the upper section of the second limiting rod 401 to the sheet receiving position. Since the upper sections of the plurality of second limiting rods 401 are respectively inclined outward from bottom to top, the upper ends of the second limiting rods 401 are more outward, which can reduce or even avoid the contact between the sheets to be palletized output on the conveyor belt 10 and the upper end surface and the edge of the upper end surface of the second limiting rod 401 during the falling process, thereby reducing or even avoiding the possibility of the sheets to be palletized being scratched by the upper end surface and the edge of the upper end surface of the second limiting rod 401. In the above technical solution, the lower sections of the plurality of second limiting rods 401 are vertical, and the vertical lower sections of the second limiting rods 401 can ensure the limiting of the sheets to be palletized and ensure the neatness of the palletizing of the sheets to be palletized.

[0031] As a preferred example, the upper sections of the plurality of second limiting rods 401 are respectively bent and extended outward from bottom to top. The bent and extended upper sections can better guide the sheets to be palletized to slide down and prevent the sheets to be palletized from being damaged. In specific implementation, the second limiting rod 401 can be bent from a straight rod.

[0032] In some embodiments, the circumferential positions and the radial positions of the plurality of first limiting rods 301 are adjustable, and the circumferential positions and the radial positions of the plurality of second limiting rods 401 are adjustable. The circumferential position refers to the position along the circumference of the blanking port 201, and the radial position refers to the position along the radius of the blanking port 201. By adjusting the positions of the plurality of first limiting rods 301 and the plurality of second limiting rods 401, sheets to be palletized with different sizes and shapes can be limited, which has the characteristic of a wide application range. For example, the positions of the plurality of first limiting rods 301 and the plurality of second limiting rods 401 can be adjusted to match circular aluminum sheets or elliptical aluminum sheets.

[0033] As a preferred solution, multiple arc-shaped tracks 202 are arranged around the blanking port 201. The lengths of the multiple arc-shaped tracks 202 extend along the circumferential direction of the blanking port 201. First connection seats 302 are fixedly connected to multiple first limiting rods 301 respectively, and second connection seats 402 are fixedly connected to multiple second limiting rods 401 respectively. The multiple first connection seats 302 and the multiple second connection seats 402 are connected to the top plate 2 through the multiple arc-shaped tracks 202. By using the multiple arc-shaped tracks 202, the circumferential positions of the multiple first limiting rods 301 and the circumferential positions of the multiple second limiting rods 401 can be adjusted. The above solution has the characteristics of simple structure and easy implementation. During specific implementation, the lower ends of the first limiting rods 301 are fixedly connected to the first connection seats 302 to form the first limiting member 3, and the lower ends of the second limiting rods 401 are fixedly connected to the second connection seats 402 to form the second limiting member 4.

[0034] Furthermore, the multiple arc-shaped tracks 202 are all arc-shaped holes. A first strip-shaped hole 303 with a length extending along the radial direction of the blanking port 201 is arranged on the first connection seat 302. The first strip-shaped hole 303 is connected to two arc-shaped tracks 202 respectively through two first bolts 8 and two nuts, so that the circumferential positions and radial positions of the multiple first limiting rods 301 are adjustable. A second strip-shaped hole 403 with a length extending along the radial direction of the blanking port 201 is arranged on the second connection seat 402. The second strip-shaped hole 403 is connected to two arc-shaped tracks 202 respectively through two second bolts 9 and two nuts, so that the circumferential positions and radial positions of the multiple second limiting rods 401 are adjustable. The above solution has the characteristics of simple structure and easy implementation.

[0035] In some embodiments, the palletizing device further includes an alignment assembly 5. The alignment assembly 5 includes a cylinder 501 with an output end facing forward, a transverse bracket 502 connected to the output end of the cylinder 501, and two pushing rods 503 respectively connected to the left and right parts of the transverse bracket 502. The cylinder 501 is installed on the top plate 2. The two pushing rods 503 are respectively vertically arranged at the left rear and right rear of the blanking port 201. The two pushing rods 503 are used to push forward the sheets to be palletized at the blanking port 201. By setting the alignment assembly 5 and using the pushing rods 503 of the alignment assembly 5 to push the sheets to be palletized at the blanking port 201, on the one hand, it can prevent the sheets to be palletized from getting stuck, and on the other hand, it can promote the alignment of the sheets to be palletized. As a preferred example, in order to better promote the alignment of the sheets to be palletized, the pushing rod 503 includes a core rod fixedly connected to the transverse bracket 502 at the lower end and multiple bearings sequentially sleeved on the core rod.

[0036] In some embodiments, the top ends of the two pushing rods 503 are of a conical structure with the tip facing upward. The conical structure can reduce the possibility of the top edges of the pushing rods 503 scratching the sheets to be palletized.

[0037] As a preferred example, a linear track 203 extending in the front-rear direction is provided on the top plate 2. The cylinder 501 is fixedly connected to the linear track 203 by bolts. When the bolts are loosened, the position of the cylinder 501 in the front-rear direction can be adjusted. When the bolts are tightened, the cylinder 501 can be fixedly connected to the linear track 203.

[0038] In some embodiments, the plurality of first limiting rods 301 and the plurality of second limiting rods 401 are all smooth rods with a circular cross-section. The use of smooth rods has the characteristics of simple structure and easy manufacturing. The smooth rods can be selected as smooth metal round rods.

[0039] In some embodiments, the plurality of first limiting rods 301 and the plurality of second limiting rods 401 are both located above the blanking port 201. During the process of the sheets to be palletized falling between the plurality of first limiting rods 301 and the plurality of second limiting rods 401, the sheets to be palletized can be aligned.

[0040] In some embodiments, the palletizing device includes four first limiting rods 301 and four second limiting rods 401. Two of the four first limiting rods 301 are arranged at the left front part of the blanking port 201 at left and right intervals, and the other two of the four first limiting rods 301 are arranged at the right front part of the blanking port 201 at left and right intervals. Two of the four second limiting rods 401 are arranged at the left rear part of the blanking port 201 at left and right intervals, and the other two of the four second limiting rods 401 are arranged at the right rear part of the blanking port 201 at left and right intervals. The four first limiting rods 301 and the four second limiting rods 401 can preferably limit the elliptical sheets. In particular, the four first limiting rods 301, the four second limiting rods 401 and the alignment assembly 5 are used in cooperation, which can basically meet the palletizing requirements of most elliptical sheets, and also has the characteristics of simple structure and easy manufacturing.

[0041] As a preferred example, the alignment assembly 5 has a left-right symmetric structure. The four first limiting rods 301 are arranged symmetrically left and right, and the four second limiting rods 401 are arranged symmetrically left and right.

[0042] In some embodiments, the palletizing device further includes a support plate 6, an electric lifting mechanism, and a receiving plate 701 for receiving the sheets to be palletized at the blanking port 201. The support plate 6 is located below the top plate 2. The support plate 6 is installed on the frame 1. The electric lifting mechanism is installed on the support plate 6, and the receiving plate 701 is installed at the top of the electric lifting mechanism. The electric lifting mechanism includes a motor 704, a roller screw, and a transmission mechanism. The transmission mechanism transmits power between the nut of the roller screw and the motor 704 to drive the screw 702 of the roller screw to lift. The receiving plate 701 is fixedly installed at the top end of the screw 702. In specific implementation, a housing 703 is fixedly installed on the support plate 6. The nut of the roller screw and the transmission mechanism can both be installed in the housing 703. The transmission mechanism can be a worm and worm gear mechanism, and the motor 704 can be fixedly installed on the support plate 6. With the above technical solution, the palletizing device is simple in overall structure and small in volume, and can meet the needs of users with strict cost control requirements and strict use site restrictions.

[0043] In specific implementation, the top plate 2 and the support plate 6 can be fixedly installed on the frame 1 by means of fasteners or welding.
