Description

Technical Field

[0001] This utility model belongs to the technical field of stator lamination output device, and particularly relates to an automatic palletizing output device for sheet products. Background Technology

[0002] In industrial production fields such as motor manufacturing, stator laminations are key components, and the palletizing process is crucial. Stator laminations are typically manufactured using a stamping process and have a sheet-like structure. Efficient, precise, and automated palletizing methods are of significant importance for improving production efficiency, ensuring product quality, and reducing labor costs.

[0003] Currently, the most common stacking method for stamped sheet products (taking stator laminations as an example) is to use an upwardly tilting guide device. This guide device, relying on its unique tilting structure design, compresses and stacks the stator laminations upwards along the inclined direction under the combined action of their own gravity and the guiding force provided by the device. As the stator laminations are continuously stacked, the synergy of gravity and the guiding force allows them to gradually accumulate into a stack of a certain height.

[0004] However, this traditional palletizing method has many obvious drawbacks. Firstly, once the stator laminations have been stacked to a predetermined quantity, manual intervention is required to remove the stacked stator laminations from the guide device. After removal, they must be fitted onto a T-shaped fixture before the palletized product is output. This additional fixture-fitting step further increases the complexity and time cost of the operation, making the entire palletizing process cumbersome and time-consuming. Secondly, during manual operation, the alignment accuracy between the stator laminations is difficult to guarantee effectively, easily leading to stator lamination misalignment and offset. This not only affects the product's appearance quality but may also adversely impact subsequent assembly processes, reducing the overall performance and reliability of the product.

[0005] With the continuous development of industrial automation technology, the requirements for automation and intelligence in production processes are increasing. Traditional stator lamination palletizing methods based on guide devices are no longer sufficient to meet the demands of modern industrial production for high efficiency, precision, and automation. Therefore, developing a new type of automatic palletizing output device that can automatically complete stator lamination palletizing, achieve precise alignment during the palletizing process, reduce manual intervention, and improve production efficiency is of significant practical importance. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic palletizing and output device for sheet products, which automatically completes the palletizing of stator sheets, achieves precise alignment during the palletizing process, and then automatically outputs the product, thereby reducing manual intervention and improving production efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An automatic palletizing and output device for sheet products includes a base, on which a lifting frame with lifting function is vertically slidably connected. A turntable is rotatably connected to the top of the lifting frame. A palletizing fixture for palletizing multiple sheet products is movably supported on the turntable. A palletizing seat is provided above the turntable. A palletizing hole is vertically provided through the palletizing seat for the palletizing fixture to move in from bottom to top and for the sheet products to fall in from top to bottom. A side tapping block is provided on the palletizing seat at a side position opposite to the top entrance of the palletizing hole. The side tapping block is used to extend into the palletizing hole and tap the sheet products laterally, so that the sheet products gather in the included angle area of ​​the palletizing hole and are aligned.

[0009] As an improvement of the automatic palletizing output device for sheet products of this utility model, two positioning seats for switching palletizing fixtures are fixed at two positions on the turntable opposite to the same palletizing hole, and the positioning seats extend movably into the palletizing hole.

[0010] As an improvement of the automatic palletizing output device for sheet products of this utility model, the top of the positioning seat is provided with a positioning groove for positioning the palletizing fixture, and the palletizing fixture is magnetically connected to the positioning seat.

[0011] As an improvement of the automatic palletizing and output device for sheet products of this utility model, the lifting frame passes vertically through the machine base, a fixed cover is fixed to the top of the machine base, the palletizing seat is fixed inside the fixed cover and its entrance is exposed in the fixed cover, and the turntable is located between the fixed cover and the machine base and is partially exposed in the fixed cover.

[0012] As an improvement of the automatic palletizing and output device for sheet products of this utility model, a rack is vertically fixed on the lifting frame, and a gear is rotatably connected to the fixed plate inside the machine base, the gear meshing with the rack.

[0013] As an improvement of the automatic palletizing and output device for sheet products of this utility model, the feeding end of the machine base is provided with a conveyor line, the discharge end of the conveyor line is aligned with the entrance of the palletizing base, and the discharge end of the conveyor line is provided with a discharge wheel to transport the sheet products conveyed on the conveyor line into the palletizing hole.

[0014] As an improvement of the automatic palletizing output device for sheet products of this utility model, there are two side-tapping blocks on the same palletizing base. The two side-tapping blocks are arranged vertically and are respectively located on the two side walls of the palletizing base that are adjacent to the top entrance of the palletizing hole, so that the tapping directions of the two side-tapping blocks are perpendicular to each other.

[0015] As an improvement of the automatic palletizing and output device for sheet products of this utility model, a U-shaped support fork is provided on the outer side of the end of the palletizing base away from the side block. The support fork is used to extend into the palletizing hole to support and transfer the sheet product to the palletizing fixture.

[0016] As an improvement of the automatic palletizing and output device for sheet products of this utility model, the palletizing base is provided with a support plate for extending into the palletizing hole to support the sheet product at the outer end of the palletizing base away from the side block, and the support plate and the support fork are distributed on two corresponding sides of the palletizing base.

[0017] As an improvement of the automatic palletizing and output device for sheet products of this utility model, the palletizing base is provided with a side pressure plate for extending into the palletizing hole to press the sheet product on the side. The side pressure plate is located between the side plate and the support fork and is close to the support fork.

[0018] Compared with existing technologies, the automatic palletizing and output device for sheet products of this utility model uses a lifting frame to control the lifting and lowering of the turntable, so that the palletizing fixture enters the palletizing hole of the palletizing base. After the stator sheets enter the palletizing hole, they are palletized on the palletizing fixture, automatically completing the stator sheet palletizing. The side tapping blocks are used to tap and align the sheet products, so that the sheet products gather in the angle area of ​​the palletizing hole, so as to achieve precise alignment during the palletizing process. Then, as the lifting frame descends, it exits the palletizing hole, and then as the turntable rotates out, the material is discharged, realizing automatic output. The entire device can reduce manual intervention and improve production efficiency. Attached Figure Description

Detailed Implementation

[0035] The embodiments of this utility model are described in detail below with reference to the accompanying drawings. The drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of this utility model.

[0036] Reference Figures 1 to 14An automatic palletizing and output device for sheet products includes a base 1, a turntable 3, and a lifting frame 2. The lifting frame 2 has a lifting function and is vertically slidably mounted on the base 1. The turntable 3 is rotatably mounted on the top of the lifting frame 2. A palletizing clamp 7 for palletizing multiple sheet products is movably supported on the turntable 3. A palletizing seat 5 is provided above the turntable 3. A palletizing hole 53 is vertically provided on the palletizing seat 5 for the palletizing clamp 7 to move in from bottom to top and for the sheet products to fall in from top to bottom. A side tapping block is provided on the side of the palletizing seat 5 opposite to the top entrance of the palletizing hole 53. The side tapping block is used to extend into the palletizing hole 53 and tap the sheet products laterally, so that the sheet products gather in the included angle area of ​​the palletizing hole 53 and are aligned.

[0037] Reference Figures 1 to 3 The feeding end (i.e., the Y-direction) of the machine base 1 is equipped with a conveyor line. In order to improve the production capacity, in this embodiment, the number of palletizing bases 5 is preferably two, and the number of conveyor lines is also preferably two. Each conveyor line is arranged along the Y-axis direction (i.e., the front-to-back direction). The discharge ends of the two conveyor lines are respectively aligned with the inlets of the two palletizing bases 5. Each conveyor line includes two front and rear transmission mechanisms 4. The two transmission mechanisms 4 are connected front and rear to form a long conveyor line. The structures of the front and rear transmission mechanisms 4 are basically the same. The specific structure of one of the transmission mechanisms 4 will be described below. Each transmission mechanism 4 includes a conveyor motor 42, a driving wheel 43, a conveyor belt 41, two idler wheels 44, and two driven wheels. The output end of the conveyor motor 42 drives the driving wheel 43 to rotate through belt drive. The two idler wheels 44 are spaced between the two driven wheels, and the driving wheel 43 is located between the two idler wheels. Directly below the position between 44, the conveyor belt 41 passes around the drive wheel 43, two idler wheels 44, and two driven wheels. The output end of the conveyor motor 42 drives the drive wheel 43 to rotate via belt drive. The drive wheel 43 drives the two driven wheels to rotate via the conveyor belt 41, thereby conveying sheet products. In order to allow the sheet products at the discharge end of the two conveyor lines to smoothly enter the stacking holes 53 of the two stacking seats 5, the discharge end of the conveyor belt 41 at the front end of each conveyor line is also equipped with a discharge wheel 45. The left and right ends of the discharge wheel 45 are rotatably connected to the baffle plates 411 on the left and right sides of the corresponding conveyor belt 41, respectively. There is a certain gap between the discharge wheel 45 and the driven wheel directly below and the conveyor belt 41 to allow a single sheet product to pass through. The rear ends of the two conveyor lines extend into the stamping machine to receive the sheet products formed by the stamping die (the stamping die forms two sheet products in one stamping).

[0038] Reference Figure 1 and Figure 4The top of the base 1 is provided with a lifting hole 12. A fixed cover 11 is fixed on the top of the base 1. The upper end of the fixed cover 11 is box-shaped, and the lower end of the fixed cover 11 is U-shaped and partially located above the base 1. The palletizing seat 5 is fixed inside the upper end of the fixed cover 11 and its top entrance is exposed to the fixed cover 11. In this embodiment, two palletizing seats 5 are preferably arranged in a staggered manner (i.e., arranged along the diagonal line at the top of the fixed cover 11) to form two palletizing lines. The turntable 3 is located between the fixed cover 11 and the base 1 and is partially exposed to the fixed cover 11 so as to transport the sheet products palletized in the two palletizing seats 5 to the outside of the fixed cover 11.

[0039] Reference Figures 9 to 12 The two palletizing bases 5 have the same structure. The structure of one palletizing base 5 will be described below. Each palletizing base 5 includes a palletizing cylinder 51 and a base plate 52. The base plate 52 and the palletizing cylinder 51 are both fixed inside the fixing cover 11. The base plate 52 has a square bottom hole 521 in an annular shape. The base plate 52 is fixedly sleeved at the bottom outlet of the palletizing cylinder 51. The palletizing cylinder 51 is square cylindrical and its top and bottom are hollowed out. The inner hole of the palletizing cylinder 51 forms the palletizing hole 53 of the palletizing base 5. The top opening of the palletizing hole 53 is the inlet of the sheet product (i.e., stator sheet 8), and the bottom opening of the palletizing hole 53 is the outlet of the palletizing clamp 7 with the stator sheet 8.

[0040] Reference Figures 9 to 12In this invention, the number of side-tapping blocks on the same palletizing cylinder 51 is preferably two. Specifically, the two side-tapping blocks are a first side-tapping block 62 and a second side-tapping block 63. Both the first side-tapping block 62 and the second side-tapping block 63 are block-shaped. The first side-tapping block 62 and the second side-tapping block 63 are arranged perpendicularly and are respectively located on the two adjacent side walls of the palletizing base 5, directly opposite the top entrance of the palletizing hole 53. This ensures that the tapping directions of the first side-tapping block 62 and the second side-tapping block 63 are perpendicular to each other, thereby subjecting the sheet-like products to constraints in different directions during the palletizing process, making the palletizing more regular and stable. Side-tapping holes are provided on the two side walls at the top entrance of the palletizing hole 53 in two different directions. Specifically, the two side-tapping holes are a first side-tapping hole 511 and a second side-tapping hole 512. The first side-tapping hole 511 is located at the upper end of the rear side wall of the palletizing cylinder 51, and the second side-tapping hole 512 is located on the left side wall of the palletizing cylinder 51. At the upper end, a first side-tapping cylinder 621 and a second side-tapping cylinder 631 are fixed on the palletizing cylinder 51. The first side-tapping cylinder 621 is located behind the palletizing cylinder 51. The first side-tapping block 62 is fixed on the output shaft of the first side-tapping cylinder 621 and is opposite to the position of the first side-tapping hole 511. The initial state of the first side-tapping block 62 is preferably located inside the first side-tapping hole 511. The second side-tapping cylinder 631 is located on the left side of the palletizing cylinder 51. The second side-tapping block 63 is fixed on the output shaft of the second side-tapping cylinder 631 and is opposite to the position of the second side-tapping hole 512. The initial state of the second side-tapping block 63 is preferably located inside the second side-tapping hole 512. In order to prevent full material, a long strip-shaped detection hole 516 is provided at the upper end of the right side wall of the palletizing cylinder 51. A full material detection sensor 517 is provided on the right side of the palletizing cylinder 51. The position of the full material detection sensor 517 is opposite to the position of the detection hole 516.

[0041] Reference Figures 9 to 12 Each palletizing cylinder 51 has a U-shaped fork 65 located on the outside of one end away from its two side blocks (i.e., the lower end of the palletizing cylinder 51). The fork 65 is inserted into the sleeve 71 of the palletizing clamp 7. The fork 65 is used to extend into the palletizing hole 53 to support and transfer sheet products onto the palletizing clamp 7. The fork 65 is specifically located on the left side of the palletizing cylinder 51. A fork cylinder 651 is fixed in front of the palletizing cylinder 51. The fork 65 is fixed on the output shaft of the fork cylinder 651. Two insertion holes 513 are provided on the side wall of the palletizing cylinder 51 near the fork 65 (i.e., the lower end of the left side wall of the palletizing cylinder 51) for the two ends of the opening of the fork 65 to pass through respectively.

[0042] Reference Figures 9 to 12To prevent the stator laminations 8 from falling off, each palletizing cylinder 51 is provided with a side pressure plate 6 for extending into the palletizing hole 53 to press the sheet-like products. The side pressure plate 6 is specifically L-shaped and located on the left side of the corresponding palletizing cylinder 51. On the same palletizing cylinder 51, the side pressure plate 6 is located between the two side blocks and the support fork 65 and close to the support fork 65. The side wall of the palletizing cylinder 51 near the corresponding side pressure plate 6 (i.e., the lower end of the left wall of the palletizing cylinder 51) is provided with a side pressure hole 514 for the side pressure plate 6 to pass through. A side pressure cylinder 61 is fixed on the left side of each palletizing cylinder 51, and the side pressure plate 6 is fixed on the output shaft of the corresponding side pressure cylinder 61.

[0043] Reference Figures 9 to 12 Each palletizing cylinder 51 has a support plate 64 on its outer side away from its two side blocks (i.e., the lower end of the palletizing cylinder 51) for extending into the palletizing hole 53 to support sheet products. On the same palletizing cylinder 51, the support plate 64 and the support fork 65 are distributed on two corresponding sides of the palletizing cylinder 51. In this embodiment, the support plate 64 is located on the right side of the corresponding palletizing cylinder 51. The support plate 64 is plate-shaped. The side wall of the palletizing cylinder 51 near the support plate 64 (i.e., the lower end of the right side wall of the palletizing cylinder 51) is provided with an insertion hole 515 for the support plate 64 to pass through. The insertion hole 515 is elongated. A support cylinder 641 is fixed on the front side wall of each palletizing cylinder 51. The support plate 64 is fixed on the output shaft on the right side of the support cylinder 641. On the same palletizing cylinder 51, the support cylinder 641 is located directly above the support fork cylinder 651.

[0044] Reference Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 11 and Figure 12 In this utility model, the same palletizing base 5 and the first side tapping block 62, the first side tapping cylinder 621, the second side tapping block 63, the second side tapping cylinder 631, the support fork 65, the support fork cylinder 651, the side pressure plate 6, the side pressure cylinder 61, the support plate 64, and the support cylinder 641 together constitute a palletizing device. The two palletizing devices are staggered front to back and left to right and are connected to two conveyor lines.

[0045] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The turntable 3 is rectangular and located directly below the two palletizing devices. Positioning seats for switching the palletizing clamps 7 are fixed at two positions opposite to the same palletizing hole 53 (i.e., the front and rear ends of the turntable 3). Since the two conveyor lines in this invention can respectively convey sheet products to the two palletizing holes 53, four positioning seats are fixed on the turntable 3. Specifically, the four positioning seats are two first positioning seats 31 and two second positioning seats 311. The two first positioning seats 31 are staggered and fixed at one end of the turntable 3 (i.e., the two first positioning seats 31 are diagonally positioned along one end of the turntable 3). The first positioning seat 311 and the second positioning seat 311 are fixed at the other end of the turntable 3 in a staggered manner (i.e., the two second positioning seats 311 are distributed along the diagonal of the other end of the turntable 3). The top of the first positioning seat 31 and the second positioning seat 311 are provided with a positioning groove 312 for positioning the palletizing fixture 7. The bottom of the positioning groove 312 is provided with a magnet so that the palletizing fixture 7 can be magnetically connected to the positioning seat. The two first positioning seats 31 and the two second positioning seats 311 can be moved into the two palletizing holes 53 as the turntable 3 is raised, so that the palletizing fixture 7 supported on the positioning seat can be raised into the corresponding palletizing hole 53.

[0046] Reference Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The lifting frame 2 is located at the bottom of the turntable 3. The lifting frame 2 vertically passes through the lifting hole 12 at the top of the base 1 (that is, the upper end of the lifting frame 2 extends outside the base 1, and the lower end of the lifting frame 2 is located inside the base 1). A rotary motor 32 is fixed inside the lifting frame 2. The output shaft at the top of the rotary motor 32 passes through the turntable 3 and is connected to the turntable 3. A rack 21 and two slide rails 22 are vertically fixed on the rear side wall of the lifting frame 2. The rack 21 is located between the two slide rails 22. The fixing plate 123 inside the base 1 is slidably set on the two slide rails 22. A lifting motor 121 is fixed on the back of the fixing plate 123. A gear 122 is rotatably connected to the fixing plate 123. The gear 122 is set at the output end of the lifting motor 121 and meshes with the rack 21.

[0047] Reference Figure 13 and Figure 14 The palletizing fixture 7 includes a base 72 and a sleeve 71. The base 72 is cubic and fits into the positioning groove 312 on the top of the positioning seat. The sleeve 71 is cylindrical and has a hollow top. The sleeve 71 is fixed to the top of the base 72 to form a T-shape. The entire palletizing fixture 7 can move up and down with the lifting action of the turntable 3.

[0048] Reference Figures 1 to 14 The working principle of the automatic palletizing and output device for sheet products of this utility model is as follows:

[0049] The stamping machine punches two sheet products in one pass (i.e., stator sheet 8, each stator sheet 8 is a ring-shaped sheet with a square outer edge and a round inner edge). The two stator sheets 8 fall onto two conveyor lines respectively. The two conveyor lines transport the two stator sheets 8 to the entrances at the top of the two stacking holes 53 respectively. Then the two stator sheets 8 fall from top to bottom into the two stacking holes 53 respectively.

[0050] As the stamping machine continues to punch, the punched stator pieces 8 continuously fall into the corresponding stacking holes 53 from the top opening of each stacking cylinder 51. In order to prevent the stator pieces 8 from falling, the support cylinder 641 on each stacking cylinder 51 drives the corresponding support plate 64 to move to the left and insert it from the insertion hole 515 into the stacking hole 53 of the stacking cylinder 51. The stator pieces 8 that fall into the two stacking holes 53 can then be stacked on the two support plates 64 respectively.

[0051] Two side-pressure cylinders 61 synchronously drive the corresponding side-pressure plates 6 to move to the right, inserting them from their respective side-pressure holes 514 into the stacking holes 53 of the corresponding stacking cylinder 51, pressing the stator plates 8 on the corresponding support plates 64 to position them. Then, two support fork cylinders 651 drive the corresponding support forks 65 to move to the right, with the two ends of the openings of the support forks 65 respectively inserting them from the corresponding two insertion holes 513 into the stacking holes 53 of the stacking cylinder 51. At this time, the support cylinder 641 first drives the support plate 64 to reset and exit, and then the side-pressure cylinder 61 drives the side-pressure plates 6 to reset and exit, so that the stator plates 8 in the stacking holes 53 can fall onto the support forks 65.

[0052] The lifting motor 121 drives the gear 122 to rotate, and the gear 122 drives the rack 21 and the turntable 3 to move upward together. The first positioning seat 31 located directly below the two stacking holes 53 and the empty stacking fixture 7 it carries move upward together with the turntable 3 until the two empty stacking fixtures 7 move upward into the two stacking holes 53 respectively. The sleeve 71 of the stacking fixture 7 passes through the opening of the support fork 65 and the inner hole of the multiple stator plates 8 on the support fork 65. The support fork cylinder 651 drives the support fork 65 to retract and reset, and the stator plates 8 on the support fork 65 can then be fitted onto the sleeve 71 of the stacking fixture 7.

[0053] The palletizing jig 7, which is not fully fitted with stator plates 8, continues to move upward until it reaches the upper end of the palletizing hole 53. On each palletizing cylinder 51, the first side-tapping cylinder 621 drives the first side-tapping block 62 to extend into the palletizing hole 53 and tap the stator plates 8 on the palletizing jig 7 forward, causing the stator plates 8 on the palletizing jig 7 to move forward a short distance and align with the front side wall of the palletizing cylinder 51. At the same time, the second side-tapping cylinder 631 drives the second side-tapping block 63 to extend into the palletizing hole 53 and tap the stator plates 8 to the right, causing the stator plates 8 on the palletizing jig 7 to move to the right a short distance and align with the right side wall of the palletizing cylinder 51. At this time, the stator plates 8 on the palletizing jig 7 are gathered in the right front angle area of ​​the palletizing hole 53 (i.e., the angle area formed by the front side wall and the right side wall of the palletizing cylinder 51). The product can be aligned by utilizing the constraint effect of the corner of the palletizing hole 53 on the product position.

[0054] As the stamped stator pieces 8 are continuously fed onto the stacking fixture 7, the stacking fixture 7 also moves down continuously. Within the same stacking hole 53, the first side block 62 and the second side block 63 can continuously tap the stator pieces 8 that have fallen off from two different directions, so that these stator pieces 8 are aligned in time after falling off. This continues until the stacking fixture 7 on the two first positioning seats 31 is full of aligned stator pieces 8.

[0055] The lifting motor 121 drives the lifting frame 2 and the turntable 3 to move down through the gear and rack structure. All the positioning seats move down with the turntable 3, and the two stacking clamps 7, which are filled with stator plates 8, can move out of the two stacking holes 53 along with the two first positioning seats 31.

[0056] Two empty palletizing jigs 7 are placed on two second positioning seats 311 respectively. The rotary motor 32 drives the turntable 3 to rotate 180 degrees. The two second positioning seats 311 and the empty jigs they carry can then rotate to the position directly below the two palletizing holes 53. At the same time, the two first positioning seats 31 and the palletizing jigs 7 they carry, which are filled with stator plates 8, can rotate to the outside of the fixed cover 11 to discharge the material. This cycle continues.

[0057] This invention relates to a palletizing device. A palletizing hole 53 is vertically oriented through a palletizing base 5. A palletizing clamp 7 is installed within the palletizing hole 53. Sheet products are palletized using the palletizing clamp 7, and the products gradually move downwards as they are stacked. A side-tapping block is positioned on the palletizing base 5, directly opposite the top entrance of the palletizing hole 53. This side-tapping block taps the palletized products on the palletizing clamp 7. The constraint effect of the corner of the palletizing hole 53 on the product position causes the sheet products to gather in the included angle area formed by adjacent sides within the palletizing hole 53. This achieves neat alignment of the sheet products within the palletizing hole 53, significantly improving the palletizing accuracy. Simultaneously, it reduces manual operation, lowers reliance on manual labor, and improves production efficiency and palletizing quality. Furthermore, this device is highly flexible and can adapt to the palletizing needs of sheet products of different specifications and shapes.

[0058] This utility model discloses an automatic palletizing and output device for sheet products. The device utilizes a lifting frame 2 to control the lifting and lowering of a turntable 3, allowing the palletizing clamp 7 to enter the palletizing hole 53 of the palletizing base 5. After the stator sheets 8 enter the palletizing hole 53, they are palletized on the palletizing clamp 7, automatically completing the stator sheet palletizing. Side-tapping blocks are used to align the sheet products, causing them to gather in the angled area of ​​the palletizing hole 53 for precise alignment during palletizing. Then, as the lifting frame 2 descends and exits the palletizing hole 53, the sheet products are discharged as the turntable 3 rotates out, achieving automatic output. The entire device reduces manual intervention and improves production efficiency. This innovative design effectively solves the problems of low efficiency, poor alignment accuracy, and excessive manual intervention in traditional palletizing methods, providing a more efficient and precise solution for the automated palletizing of sheet products.

[0059] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
